The present disclosure provides a film cutting method, a film cutting device, a composite film, a backlight module and a display device. The film material cutting method includes: using a cutting tool provided with a viscous material to cut a composite film that includes at least two laminated optical films, with the viscous material on the cutting tool being transferred to a cutting end surface of the composite film during cutting; and, curing the viscous material on the cutting end surface.

The present invention relates to an electrode sheet cutting apparatus including an upper cutter and a lower cutter configured to apply force to opposite surfaces of an electrode sheet while moving at the same speed, wherein the electrode sheet is cut from one side to the other side, whereby deformation of the electrode sheet is prevented and generation of foreign matter is reduced, and an electrode sheet cutting method using the same.

The present technology relates to an apparatus for cutting an electrode of a battery, and the apparatus includes: an all-in-one cutting cartridge module including an upper knife and a lower knife; and a cradle where the all-in-one cutting cartridge module is mounted.

Herein, the all-in-one cutting cartridge module includes a module frame and an upper knife holding unit which fixes and supports the upper knife and is supported in a manner that is vertically slidable on the module frame, and the lower knife is coupled to a lower portion of the module frame to face the upper knife.

The assembly work is very simple in the electrode cutting apparatus of the present invention. Further, since the upper knife and the lower knife are installed at the module cartridge, it is possible to quantitatively adjust the clearance and straightness of the upper knife and the lower knife in advance.

A cutter device, comprising: a first blade including a first cutting edge extending in a first direction; a second blade including a second cutting edge extending in a second direction; and a guide portion provided at a position anterior to the second blade in the second direction, wherein the second blade moves in the second direction to cut a recording medium while leaving a part thereof uncut, and when the second blade is located posterior, in the second direction, to a position where the second blade cuts the recording medium, at least a part of the guide portion is located to protrude farther in the first direction than the first cutting edge, or located at a same position as the first cutting edge.

A tape detection mechanism including a first pivoting member provided to pivot about a detection pivoting shaft, a second pivoting member linked, to be configured to pivot, to a pivot linking portion provided on the first pivoting member, a pivoting contact section with which the second pivoting member comes into contact when the first pivoting member and the second pivoting member pivot in a first pivoting direction about the detection pivoting shaft as the tape, which is fed thereto, comes into contact with the first pivoting member, and a sensor which detects the second pivoting member which comes into contact with the pivoting contact section.

A cutter for cutting a linear element includes a support frame, a pair of blade holders disposed opposite to each other and movably disposed on the support frame, a pair of blades facing each other and each disposed on one of the pair of blade holders, a pair of holding blocks facing each other and each disposed on one of the pair of blade holders, and a driving device disposed on the support frame. The driving device drives the pair of blade holders to move synchronously in a direction approaching each other or a direction separating away from each other. The pair of holding blocks clamp the linear element and the pair of blades cut off the linear element clamped by the pair of holding blocks while the pair of blade holders move synchronously in the direction approaching each other.

A cutter includes a base, a first blade arranged perpendicularly on the base, a second blade arranged on the base, and a third blade arranged on the base. The second blade is parallel to the first blade along a length direction and forms a first included angle with the base. The third blade is located on a side of the second blade away from the first blade. The third blade is parallel to the first blade along the length direction and forms a second included angle with the base. The second blade and the third blade are not parallel in the width direction. Cutting edges of the first blade, the second blade, and the third blade are in a same plane.

The present disclosure provides a film cutting method, a film cutting device, a composite film, a backlight module and a display device. The film material cutting method includes: using a cutting tool provided with a viscous material to cut a composite film that includes at least two laminated optical films, with the viscous material on the cutting tool being transferred to a cutting end surface of the composite film during cutting; and, curing the viscous material on the cutting end surface.

A cutting unit in a packaging machine for separating a series of finished packages containing a predetermined number of products from a continuous packaging or bundle advancing on a conveyor, comprising a frame, which supports a pair of side cutting blades and a pair of upper cutting and lower cutting blades arranged facing four sides of the continuous bundle, wherein the two pairs of blades can be alternately moved forward and backward between a rest position separated from the continuous bundle, and an engagement position on the continuous bundle containing groups of the products arranged on two flanked rows and wrapped in a film of extendable plastic material, each pair of blades being driven in an alternating forward and backward movement for engagement with and disengagement from the continuous bundle by a double crank actuated by a single motor.

A cutter for cutting a linear element includes a support frame, a pair of blade holders disposed opposite to each other and movably disposed on the support frame, a pair of blades facing each other and each disposed on one of the pair of blade holders, a pair of holding blocks facing each other and each disposed on one of the pair of blade holders, and a driving device disposed on the support frame. The driving device drives the pair of blade holders to move synchronously in a direction approaching each other or a direction separating away from each other. The pair of holding blocks clamp the linear element and the pair of blades cut off the linear element clamped by the pair of holding blocks while the pair of blade holders move synchronously in the direction approaching each other.
