[0001] The utility model belongs to the technical field of cast polyethylene films, and in particular relates to a clamping and traction device for cast polyethylene films. Background Art

[0002] Cast polyethylene film is a commonly used packaging material. When packaging products, it is necessary to first pull out a sufficiently long section of film from the film roll so that it can completely cover the product, then cut it horizontally, and proceed with other processes.

[0003] At present, during the use of existing cast polyethylene films, it is usually necessary to use a clamp to clamp the end of the film and cooperate with a moving mechanism to achieve the above-mentioned traction work. However, when the clamp clamps the end of the film, the clamp may cause a dent in the part clamped by the clamp due to excessive clamping force or a small clamping area, thereby affecting subsequent use. Utility Model Content

[0004] The utility model aims to provide a clamping and traction device for cast polyethylene film, aiming to solve the problem in the prior art that during the use of the existing cast polyethylene film, it is usually necessary to use a clamping claw to clamp the end of the film and cooperate with a moving mechanism to achieve the above-mentioned traction work, but when the clamping claw clamps the end of the film, the clamping force is too large or the clamping area is too small, resulting in a concave situation in the part clamped by the clamping claw, thereby affecting the subsequent use.

[0005] To achieve the above object, the utility model provides the following technical solution: A clamping and pulling device for cast polyethylene film, comprising a bottom plate, a mounting frame connected to the top of the bottom plate, an electric telescopic rod installed on the top of the mounting frame, and a connecting plate connected to the output end of the electric telescopic rod;

[0006] The top of the connecting plate is connected to a guide rod, the surface of the connecting plate is penetrated by two connecting rods, one end of the two connecting rods is connected to a clamping plate, one end of the two connecting rods is connected to a limiting block, and the outer wall of the connecting rod is sleeved with a spring.

[0007] As a preferred embodiment of the clamping and traction device for cast polyethylene film of the utility model, the two connecting rods are symmetrically distributed.

[0008] As a preferred embodiment of the clamping and traction device for cast polyethylene film of the utility model, the spring is located between the connecting plate and the clamping plate.

[0009] As a preferred clamping and traction device for cast polyethylene film of the utility model, the clamping plate forms an elastic structure through a connecting rod, a limit block, a spring and a connecting plate.

[0010] As a preferred clamping and traction device for cast polyethylene film of the utility model, a first convex block is arranged at the bottom of the clamping plate, and a second convex block is arranged at the top of the bottom plate.

[0011] As a preferred embodiment of the clamping and traction device for cast polyethylene film of the utility model, the second protrusion is located directly below the first protrusion.

[0012] As a preferred embodiment of the clamping and traction device for cast polyethylene film of the utility model, one end of the two mounting seats is provided with a mounting hole.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting one end of the cast polyethylene film between the bottom plate and the clamping plate, and then starting the electric telescopic rod to drive the connecting plate, the bottom of the clamping plate will gradually contact the cast polyethylene film, and as the connecting plate is continuously pressed down, the elastic structure between the clamping plate and the connecting plate can play a buffering role, thereby avoiding the occurrence of local depression caused by excessive clamping force or too small clamping area.

[0015] 2. By setting the wavy first and second protrusions, when the clamping plate and the bottom plate clamp one end of the cast polyethylene film, the clamping area can be effectively increased, thereby avoiding the falling off of the cast polyethylene film when the moving mechanism is used to pull the cast polyethylene film, thereby improving stability.
