Description

Technical Field

[0001] The utility model relates to the technical field of automatic cutting, and more specifically, to an automatic cutting machine for producing PVC thin plates. Background Art

[0002] PVC board is a board made of polyvinyl chloride as raw material. It is a vacuum blister film used for surface packaging of various panels and is used in many industries such as building materials, packaging, and medicine. PVC board has the characteristics of long service life, waterproof and moisture-proof, easy installation and low price. With the rapid development of society, the demand for PVC board in the market is increasing. Cutting has also become an extremely important step in the production process of PVC board.

[0003] For PVC board cutting, some PVC board cutting machines in factories are mostly composed of a frame, a blade, a drive motor, etc. The PVC board is placed on the frame, and then the drive motor is turned on to drive the blade to cut the PVC board once. This type of device cannot perform the same cutting continuously, resulting in low cutting efficiency and cannot guarantee the same cutting accuracy. In order to solve the shortcomings of the existing technology, we propose an automatic cutting machine for PVC sheet production. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides an automatic cutting assembly, including a mounting bracket, and starts a No. 1 motor to drive two first gears to rotate, so that the connecting column and the connecting rod rotate at the same time, and then drives the bearing to rotate. At this time, the two cutting knives move relative to each other, and the limit bolt moves up and down under the fixed block through the U-shaped piece to ensure that the cutting knives will not deviate. With the above structure, the cutting action is completed through the relative movement of the two cutting knives, and continuous and equal cutting is realized. Moreover, the cutting length can be changed by changing the rotation speed of the No. 1 motor.

[0014] The utility model starts the second motor by setting up a feeding guide component, including a limit block. As the two second gears mesh with each other, the rollers are driven to rotate relative to each other. By utilizing the above structure, the feeding process is realized through the relative movement of the two rollers. By setting the guide plates, the material transmission path is realized and the cutting guide is completed between the guide plates. The automatic feeding greatly reduces the danger of mechanical operation to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The two cutting knives 36 are symmetrically arranged and kept on the same vertical line, and the two cutting knives 36 move relative to each other through the cooperation of the two first gears 37;

[0028] The cutting action is accomplished by the relative movement of the two cutting knives 36 .
