Spiral conveying mesh chain

Abstract

A spiral conveying mesh chain which pertains to the field of conveying equipment includes a conveying mesh chain main body. The edge of the inner side of the conveying mesh chain main body is uniformly provided with passive teeth. The passive teeth are used to engage with driving teeth on the outer periphery of a rotating drum for driving the conveying mesh chain main body to rotate. The contact surface of the passive tooth and the driving tooth is one item selected from a group consisting of an inclined surface, an arc-shaped surface, a V-shaped contact surface, and a T-shaped contact surface, so that the force direction between the passive tooth and the driving tooth is inwardly deviated relative to the rotation direction of the conveying mesh chain.

Claims

1. A spiral conveying mesh chain, comprising: a conveying mesh chain main body; wherein an edge of an inner side of the conveying mesh chain main body is uniformly provided with passive teeth; the passive teeth engage with driving teeth on an outer periphery of a rotary drum for driving the conveying chain mesh main body to rotate, wherein there is no gap between a top end of the passive teeth and a surface adjacent the driving teeth; and each contact surface between the passive tooth and the driving tooth is selected from a group consisting of an inclined surface, an arc-shaped surface, a V-shaped contact surface, and a T-shaped contact surface, so that a force direction between the passive tooth and the driving tooth is inwardly deviated relative to a rotation direction of the conveying mesh chain main body, when the conveying mesh chain body has a tightening force on the rotary drum, the passive teeth of the conveying mesh chain body do not separate and do not detach from the driving teeth of the rotary drum to provide the conveying mesh chain body to rotate with the rotary drum continuously.

2. The spiral conveying mesh chain according to claim 1, wherein the contact surface between the passive tooth and the driving tooth is the T-shaped contact surface.

DETAILED DESCRIPTION

First Embodiment

(8) As shown in FIGS. 1 and 2, the present invention includes a conveying mesh chain 1 and a rotary drum 2. The edge of the inner side of the conveying mesh chain 1 is uniformly provided with passive teeth 4. The outer periphery of the rotary drum 2 is provided with driving teeth 3 that are engaged with the passive teeth 4. The contact surface between the driving tooth 3 and passive tooth 4 is an arc-shaped surface, and the concave arc of the arc-shaped surface is arranged on the passive tooth 4.

Second Embodiment

(10) As shown in FIG. 3, the structure of the second embodiment is basically the same as the structure of the first embodiment. The difference is that the contact surface between driving tooth 5 and the passive tooth 6 is an arc-shaped surface, and the concave arc of the arc-shaped surface is provided on the driving teeth 5.

(11) In this embodiment, the force direction c between the driving tooth 5 and passive tooth 6 is inwardly deviated relative to the rotation direction d of the conveying mesh chain 1, so that when the tightening force of the conveying mesh chain is relatively small, passive teeth 6 of the conveying mesh chain will not separate and detach from the driving teeth 5 on the rotary drum, and the conveying mesh chain can rotate with the rotary drum, accordingly.

Third Embodiment

(12) As shown in FIG. 4, the structure of the third embodiment is basically the same as the structure of the first embodiment. The difference is that the contact surface between driving tooth 7 and passive tooth 8 is an inclined surface inclined towards the side along the rotation direction.

(13) In this embodiment, the force direction e between the driving tooth 7 and the passive tooth 8 is inwardly deviated relative to the rotation direction f of the conveying mesh chain 1, so that when the tightening force of the conveying mesh chain is relatively small, the passive tooth 8 of the conveying mesh chain will not separate and detach from the driving tooth 7 of the rotary drum, and the conveying mesh chain can rotate with the rotary drum, accordingly.

Fourth Embodiment

(14) As shown in FIG. 5, the structure of the fourth embodiment is basically the same as the structure of the first embodiment. The difference is that the contact surface between driving tooth 9 and passive tooth 10 is a V-shaped surface.

(15) In this embodiment, the force direction g between driving tooth 9 and passive tooth 10 is inwardly deviated relative to the rotation direction h of conveying mesh chain 1, so that when the tightening force of the conveying mesh chain is relatively small, the passive teeth 10 of the conveying mesh chain will not separate and detach from the driving tooth 9 on the rotary drum, and the conveying mesh chain can rotate with the rotary drum, accordingly.

Fifth Embodiment

(16) As shown in FIG. 6, the structure of the fifth embodiment is basically the same as the structure of the first embodiment. The difference is that the contact surface between driving tooth 11 and passive tooth 12 is a T-shaped surface.

(17) In this embodiment, the force direction x between the driving tooth 11 and passive tooth 12 is inwardly deviated relative to the rotation direction y of conveying mesh chain 1, so that when the tightening force of the conveying mesh chain is relatively small, the passive tooth 12 of the conveying mesh chain will not separate and detach from the driving tooth 11 on the rotary drum, and the conveying mesh chain can rotate with the rotary drum, accordingly.

(18) The above-mentioned embodiments are described by taking counterclockwise rotation cooperation of the conveying mesh chain and rotary drum as examples. The principle of clockwise rotations are the same, so they will not be repeated hereinafter.
