Description

Technical Field

[0001] This utility model relates to the technical field of PVC packaging film processing equipment, and in particular to a PVC packaging film edge cutting mechanism. Background Technology

[0002] A PVC packaging film trimming mechanism is a piece of equipment used in PVC film packaging production lines. Its main function is to cut PVC film to the required size, remove excess edge parts, and ensure that the packaging film is neat and aesthetically pleasing.

[0003] Currently, when trimming the edges of PVC packaging film, a traction device is generally used to pull the PVC packaging film to be trimmed, moving it on a positioning roller. A cutting blade above the positioning roller cuts the edges of the PVC packaging film as it passes. After cutting, the packaging film is collected by a winding roller. However, the waste material from the cut edges usually falls to the ground, requiring manual cleaning at regular intervals. Furthermore, because the waste material from the edges of PVC packaging film is lightweight, it is easily blown away, affecting the working environment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, and it includes: a mounting frame; a positioning roller, which is disposed on one side of the mounting frame; a cutting edge assembly, which is connected above the positioning roller; a collecting rod, which is connected to one side of the mounting frame; a first winding frame, which is connected to the mounting frame on one side and is provided with a first winding roller; and a second winding frame, which is connected to the mounting frame on one side and is provided with a second winding roller.

[0005] As a further description of the above technical solution: the edge cutting assembly includes a bidirectional lead screw, one end of which is connected to a drive motor, the drive motor is connected to a mounting bracket, a first drive block and a second drive block are connected on the bidirectional lead screw, and an edge cutting blade is connected below both the first drive block and the second drive block.

[0006] As a further description of the above technical solution: a mounting plate is connected to one side of the mounting frame, and one end of the material collecting rod is detachably connected to the mounting plate by bolts.

[0007] As a further description of the above technical solution: a baffle is provided at the end of the collecting rod away from the mounting plate.

[0008] As a further description of the above technical solution: a guide roller is provided on the mounting frame.

[0009] As a further description of the above technical solution: multiple material collecting rods are provided, and the material collecting rods are located below the positioning rollers.

[0010] As a further description of the above technical solution: the positioning roller is connected to the electric lifting rod below, and the electric lifting rod is detachably connected to the mounting frame through the base plate.

[0011] As a further description of the above technical solution: the connection between the first winding frame and the second winding frame and the mounting frame is detachable.

[0012] The above technical solution has the following advantages or beneficial effects:

[0013] This invention uses an edge-cutting assembly to cut the PVC packaging film on the positioning roller. The cut packaging film is then wound up by the first winding roller on the first winding frame. The excess material generated from the edge cutting can be attached downwards to the bottom of the collecting rod by the positioning roller. The excess material can then be wound up by the second winding roller on the second winding frame via the collecting rod for centralized collection. This eliminates the need for the excess material to scatter on the ground, improves the working environment, and increases the efficiency of the device. Attached Figure Description
