[0008] The principle and effect of the technical solution are as follows:

[0009] When trimming the film, first place the film on the telescopic plate component, then move the two movable seats by the second drive component, and then expand or contract the telescopic plate component, so that the burrs on both sides of the film are located outside the telescopic plate component, then fix the film by the clamping component, and then drive the telescopic plate component to move towards the cutter by the first drive component. During the process of the telescopic plate component carrying the film passing through the cutter, the cutter cuts the burrs protruding from both sides of the telescopic plate component, thereby completing the trimming of the film.

[0010] Through the above arrangement, the device can be applied to films of different sizes by expanding or contracting the telescopic plate component by moving the movable seats. The cutter is arranged on the side of the two movable seats away from each other, which can trim the film during the movement of the telescopic plate component. This simplifies the operation steps and allows trimming of both sides of the film at one time, thereby improving the work efficiency of trimming the film.

[0011] In the utility model, both sides of the cutter are provided with knife edges.

[0012] The principle and effect of the technical solution are as follows:

[0013] After the telescopic plate component carrying the film completely passes through the cutter, the staff can take down the trimmed film and install the next film to be trimmed, or take down the trimmed film and adjust the distance between the two movable seats again, then rotate the trimmed film by 90° and fix it on the top of the telescopic plate component again, then drive the telescopic plate component to reset by the first drive component, and complete the trimming work again.

[0014] Through the above arrangement, the film fixed on the top of the telescopic plate component can be trimmed again during the resetting of the telescopic plate component, thereby further improving the work efficiency of trimming the film by the device.

[0015] In the utility model, the telescopic plate assembly includes base plate and moving plate, two groups are symmetrically arranged on the both sides of base plate, the top of movable seat is provided with sliding slot along first direction, the bottom of two moving plates is respectively slidably embedded in corresponding sliding slot, the both sides of the top of base plate are respectively provided with a plurality of clamping grooves, the side of two moving plates close to each other is fixedly provided with comb plate, the comb teeth of each comb plate are respectively slidably inserted in corresponding clamping groove.

[0016] In the utility model, the both ends of the top of two moving plates are respectively fixedly provided with electric push rod, the clamping assembly includes pressing plate movably arranged above two moving plates, the both ends of the bottom of two pressing plates are respectively fixedly connected with the output end of corresponding electric push rod.

[0017] The principle and effect of the technical scheme are as follows:

[0018] In the initial state, two moving plates are respectively located close to base plate, when second drive assembly drives two movable seats to move away from base plate, two movable seats respectively pull corresponding moving plate to move away from base plate, the comb teeth of comb plate respectively slide along the length direction of clamping groove, then extend electric push rod, make pressing plate separate from moving plate, then place the adhesive film to be trimmed to the appropriate position on the top of telescopic plate assembly, finally contract electric push rod until pressing plate and moving plate clamp the adhesive film.

[0019] Through the above setting, the purpose that clamping assembly fixes adhesive film is achieved, and the purpose that telescopic plate assembly is extended or contracted by moving movable seat is achieved, by setting comb plate, the deformation of adhesive film caused by downward collapse can be avoided, and the trimming quality is further improved.

[0020] In the utility model, the top of workbench is provided with first recess along first direction, the bottom of base plate is fixedly provided with first connecting block, the first drive assembly includes threaded rod rotatably arranged in first recess, and first guide rod fixedly arranged in first recess on the both sides of threaded rod, first connecting block is sleeved on threaded rod and slidably sleeved on two first guide rods, and the side wall of workbench is fixedly provided with first motor in transmission connection with threaded rod.

[0021] In the utility model, the top of workbench is provided with second recess on the both sides of first recess, the bottom of two movable seats is respectively fixedly provided with second connecting block, the second drive assembly includes bidirectional screw rotatably inserted in two second recesses, and second guide rod fixedly arranged in two second recesses on the both sides of bidirectional screw, two second connecting blocks are symmetrically sleeved on the positive and negative threaded segments of bidirectional screw and are respectively slidably sleeved on corresponding second guide rods, and the side wall of workbench is fixedly provided with second motor in transmission connection with bidirectional screw.

[0022] The principle and effect of the technical scheme are as follows:

[0023] Because the first guide rod and the second guide rod respectively restrict the rotation of the first connecting block and the second connecting block, when the threaded rod rotates, the first connecting block and the base plate move with the rotation of the threaded rod. When the base plate moves, the slot drives the comb plate and the moving plate to move. When the bidirectional screw rotates, the two second connecting blocks and the corresponding movable seats move closer to or further away from each other with the rotation of the bidirectional screw.

[0024] The above configuration achieves the goal of enabling the first drive component to move the telescopic plate component and the second drive component to move the two movable seats.

[0025] In this invention, a material collection tray is fixedly installed on the bottom of each of the two movable seats on the side furthest from each other, below the cutter. This arrangement allows for the collection of burrs cut off, reducing the workload of workers collecting waste and preventing waste from falling into the first or second groove, thus ensuring smooth operation of the device.
