Description

Technical Field

[0001] This utility model belongs to the field of film coating machine technology, and particularly relates to an elastic shock absorption structure for a film pressing wheel. Background Technology

[0002] A laminating machine is a device used to apply protective film to the surface of a product, commonly used in packaging, printing, and the production of some electronic products. It uses heat and pressure to cover the product surface with a film, providing protection against dust, moisture, and scratches. Laminating machines are generally divided into two types: cold laminating machines and hot laminating machines.

[0003] The pressure roller, also known as the pressure roller or hot roller, is the core component of the mulching machine. It is directly responsible for applying continuous and uniform pressure to the film covering the land surface, ensuring that the film is firmly and smoothly bonded to the land.

[0004] Existing film-pressing machines' pressing rollers, due to contact with uneven ground, are often subjected to significant impacts and vibrations during use. This not only causes wear on the pressing rollers themselves, reducing their service life, but may also affect the film-pressing effect. To solve this problem, this utility model proposes an elastic shock-absorbing structure for the pressing rollers. Utility Model Content

[0005] The purpose of this invention is to provide an elastic shock-absorbing structure for a pressure roller to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic damping structure for a pressure roller, comprising a carrier plate, pressure rollers symmetrically arranged on both sides of the carrier plate, a mounting block provided on the bottom surface of the carrier plate, a rotating shaft passing through the mounting block and penetrating the pressure rollers, a cylinder provided in the middle of the top surface of the carrier plate, a U-shaped frame provided inside the cylinder, the two sides of the U-shaped frame being connected to the inner wall of the cylinder by a rod shaft, and a first damping spring symmetrically arranged between the bottom surface of the U-shaped frame and the bottom surface of the cylinder.

[0007] Preferably, a frame is provided above the U-shaped frame, and a connecting block is provided between the bottom surface of the U-shaped frame and the frame. The two sides of the connecting block are connected to the inner wall of the U-shaped frame by a rod shaft.

[0008] Preferably, wheels are symmetrically arranged on both sides of the vehicle frame.

[0009] Preferably, the top surface of the carrier plate is symmetrically provided with auxiliary elastic damping components on both sides of the cylinder.

[0010] Preferably, the auxiliary elastic damping assembly includes a sleeve, the top of which is connected to the bottom surface of the vehicle frame, and a through hole is formed on the bottom surface of the sleeve. The inner diameter of the through hole is smaller than the inner diameter of the sleeve. A connecting rod passes through the through hole, the bottom of which is connected to the top surface of the carrier plate, and a second damping spring is provided at the top of the connecting rod inside the sleeve.

[0011] Preferably, the second damping spring is sleeved on the connecting rod, and the top two sides of the connecting rod are symmetrically provided with limiting blocks. The top surface of the second damping spring abuts against the bottom surface of the limiting block, and the bottom surface of the second damping spring abuts against the inner bottom surface of the sleeve.

[0012] This utility model has at least the following beneficial effects:

[0013] This utility model provides an elastic damping structure for a pressure roller. By setting a first damping spring and an auxiliary elastic damping component on the bottom surface of a U-shaped frame, the pressure roller is elastically buffered, which not only ensures the pressure effect but also reduces the wear of the pressure roller and improves its service life.
