DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present disclosure are clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely some embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without making creative efforts shall fall within the protection scope of the present disclosure.

[0029] Referring to the figures, the present disclosure provides a technical solution, as shown in FIG. 1 to FIG. 7:

[0030] An embroidery clamping device includes an embroidery piece clamping main body 1 and a basic pedestal 2. The embroidery piece clamping main body 1 is assembled on the basic pedestal 2.

[0031] The embroidery piece clamping main body 1 includes an embroidery base 12, an embroidery rotating handle 11, a first clamping member 13, a second clamping member 14, a rotary clamping member 15, and a guide structure composed of a through mounting slot 17 and a protrusion 16. The embroidery rotating handle 11 is welded and fixed at a bottom of the embroidery base 12. A side surface of the embroidery base 12 is provided with the first clamping member 13 and the second clamping member 14 through bolts. The rotary clamping member 15 is movably connected to the embroidery base 12. The through mounting slot 17 is formed in a middle portion of the embroidery base 2. The protrusion 16 is integrally formed at a bottom of the first clamping member 13. The protrusion 16 is slidably assembled in the through mounting slot 17. The rotary clamping member 15 is welded with a rotary screw rod 18 which penetrates through the through mounting slot 17 and is threadedly connected to the first clamping member 13.

[0032] A cross section of the through mounting slot 17 is square-shaped and adapts to a "T" - shaped protrusion at the bottom of the first clamping member. This structure can play a role in guiding the sliding of the first clamping member 13, and limit detachment of the first clamping member 13 from the base, thus further improving the stability of the clamping assembly. An inner wall of the through mounting slot can be coated with a wear-resistant coating (such as a polytetrafluoroethylene coating) to reduce frictional resistance when the protrusion slides, so that it is smoother to adjust the first clamping member 13. Meanwhile, wear of components is reduced, and the service life of the device is prolonged.

[0033] By the adapting structure of the square-shaped through mounting slot 17 and the "T" - shaped protrusion, the detachment of the first clamping member 13 is limited. In conjunction with the friction between an embroidery surface and the clamping assemblies, the clamping assemblies cannot shift after adjustment, thus ensuring that the clamping distance can be stably maintained after adjustment, avoiding distance changes caused by vibration during embroidering, and effectively solving the problems of loose clamping and displacement of embroidery pieces in an existing embroidery frame. By testing, after the device clamps an embroidery piece, the displacement of the embroidery piece does not exceed 0.5 mm in case of repeated stitching of an embroidery needle. The displacement is much less than a displacement standard of 1 to 2 mm in the existing embroidery frame.

[0034] An extension direction of the through mounting slot 17 is consistent with an arrangement direction of the first clamping member 13 and the second clamping member 14.

[0035] A clamping surface of the rotary clamping member 15 is parallel to a clamping surface of the first clamping member 13.

[0036] The basic pedestal 2 is rotatably connected with a pedestal rotating handle 21. The threaded connection between the pedestal rotating handle 21 and the embroidery rotating handle 11 is detachable. An antiskid supporting leg made of a rubber material is adhered at a bottom of the basic pedestal 2.

[0037] The embroidery rotating handle 11 and a secondary rotary adjustment assembly of the basic pedestal ensure convenience of angle adjustment, and avoid slippage and looseness during the adjustment, so that an angle adjustment range of the device expands to any angle within 360. Compared with the adjustment range of the existing embroidery frame of 90 to 180, this adjustment range can meet operation needs of various stitching methods. An embroiderer does not need to frequently adjust the posture. This can reduce the shoulder and neck fatigue. According to trial feedback of a user, the fatigue caused by continuous embroidering for two hours is reduced by 40% compared with the fatigue caused by use of the traditional embroidery frame.

[0038] A positioning hole is formed in a position, corresponding to the second clamping member 14, on the embroidery base 12. A through hole is formed in the second clamping member 14. The second clamping member 14 is fixed to the embroidery base 12 by causing a bolt to sequentially penetrate through the through hole and the positioning hole.

[0039] Each of the above components can be mounted independently, so that the service life of the device is prolonged to more than five years. Meanwhile, the components employ a modularized design, so that when a component is damaged, there is no need to replace the entire device. This reduces the usage cost of a user and has high economy.

Assembling steps of the device in this embodiment

[0040] Step 1: Fix the embroidery rotating handle 11 to the bottom of the embroidery base 12 through threaded connection. After the connection is completed, confirm again to ensure that the rotating handle is not loose relative to the base.

[0041] Step 2: Slide the T-shaped protrusion at the bottom of the first clamping member 13 into the through mounting slot 17 such that the first clamping member 13 can slide along a slot body.

[0042] Step 3: Fix the second clamping member at a preset position of the embroidery base (drill and tap the positioning hole in advance), to ensure that the arrangement direction of the second clamping member 14 and the first clamping member 13 is consistent with the extension direction of the through mounting slot 17.

[0043] Step 4: Connect the rotary screw rod 18 to the rotary clamping member 15 through threads, so that the rotary screw rod 18 rotates synchronously with the rotary clamping member. Then, threadedly connect the rotary screw rod 18 through the through mounting slot 17 to a threaded hole of the first clamping member 13, to complete assembling of the embroidery piece clamping main body 1.

[0044] Step 5: Detachably connect the pedestal rotating handle 21 of the basic pedestal to the embroidery rotating handle 11 through a bolt and a nut, to complete assembling of the entire device.

A clamping and debugging method of this embodiment

[0045] For an embroidery piece with a length less than 2 cm in an axial direction:

[0046] In a first step, the embroidery piece is placed between the cylinder 19 and the first clamping member 13, so that an end surface of the embroidery piece is parallel to an outer surface of the embroidery piece clamping main body 1. The embroidery piece is gently held with a hand to ensure that the embroidery piece is in a horizontal state.

[0047] In a second step, the rotary clamping member 15 is rotated clockwise to drive the rotary screw rod 18 to rotate. It is observed that the first clamping member 13 slides along the through mounting slot 17 toward the cylinder. In this case, the rotation is stopped. The embroidery piece is pulled gently with the hand to confirm that the embroidery piece is not loose.

[0048] In a third step, if it is found that the embroidery piece skews slightly, the rotary clamping member is finely adjusted (clockwise/counterclockwise rotation does not exceed 5). The rotary screw rod 18 is used to push the first clamping member 13 to finely adjust the position until the embroidery piece is accurately positioned.

[0049] For an embroidery piece with a length greater than 2 cm in the axial direction:

[0050] In a first step, the embroidery piece is placed between the first clamping member 13 and the second clamping member 14, so that an end surface of the embroidery piece is perpendicular to an outer surface of the embroidery piece clamping main body 1. The position of the embroidery piece is adjusted to ensure that the embroidery piece is in a vertical state.

[0051] In a second step, the rotary clamping member 15 is rotated anticlockwise to drive the first clamping member 13 to slide toward the second clamping member 14 until the embroidery piece is clamped. In this case, two ends of the embroidery piece are pressed with hands to confirm that the embroidery piece does not shake.

[0052] In a third step, if a fabric of the embroidery piece is a flexible material (such as silk), a layer of thin cotton cloth can be placed between each clamping member and the embroidery piece to avoid an excessive clamping force from damaging the fabric, while enhancing friction and improving clamping stability.

[0053] In summary, when an embroidery piece needs to be clamped, if a length of the embroidery piece in the axial direction is less than 2 cm, the embroidery piece is placed between the cylinder 19 and the first clamping member 13. The rotary clamping member 15 is rotated to drive the rotary screw rod 18 to rotate. Due to the threaded connection between the rotary screw rod 18 and the first clamping member 13, the first clamping member 13 slides along the through mounting slot 17 in a guided manner through the protrusion 16, and the rotary screw rod 18 can push the first clamping member 13 to approach the cylinder 19 while rotating, until the embroidery piece is clamped. In this case, the end surface of the embroidery piece is parallel to the outer surface of the embroidery rotating handle 11.

[0054] If the length of the embroidery piece in the axial direction is greater than 2 cm, the embroidery piece is placed between the first clamping member 13 and the second clamping member 14. By adjusting the position of the first clamping member 13, in conjunction with the second clamping member 14, the embroidery piece is clamped. In this case, the end surface of the embroidery piece is perpendicular to the outer surface of the embroidery piece clamping main body 1.

[0055] During the embroidering, the embroidery base 12 can be rotated by rotating the embroidery rotating handle 11, to adjust the angle of the embroidery piece. Or, the angle of the embroidery rotating handle 11 can be adjusted for the second time by rotating the pedestal rotating handle 21, to meet different embroidery operation requirements.

[0056] Although the embodiments of the present disclosure have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present disclosure. The scope of the present disclosure is defined by the accompanying claims and their equivalents.
