A plurality of support plates are fixedly connected to the bottom of the bottom plate. The beneficial effects are as follows: If the plastic is not fixed during the cutting process, other parts except the cutting area may be damaged during the cutting process. In this device, through the arrangement of structures such as a fixing plate, before cutting, the plastic sheet is placed on the bottom plate. By rotating the threaded column, the connecting rod is used to push the fixing plates to approach each other, thereby fixing the plastic sheet. With this design, the distance between the fixing plates is adjustable, so that the device can be applicable to the cutting of sheets of different sizes. After the sheet is fixed, the knife plate is lowered by the handle, and the plastic is cut by the cutting knife on the knife plate. The waste generated during the cutting process falls below the bottom plate through the cutting groove, and there will be no situation of splashing everywhere, which is convenient for the collection and sorting of waste.

[0021] For this specific embodiment, the fixing frame 102 is fixedly connected to the working table 101 and is located above the working table 101. The two placing plates 103 are fixedly connected to the fixing frame 102 and are located above the fixing frame 102.

Each set of limiting members includes an adjusting mechanism 104, a sliding block 105, a connecting frame 106, a plurality of rotating rods 107, and a plurality of guiding rollers 108. The adjusting mechanism 104 is threadedly connected to the placing plate 103 and penetrates through the placing plate 103. The sliding block 105 is detachably connected to the adjusting mechanism 104 and is located inside the adjusting mechanism 104.

The material is placed above the conveying member, and the anti-deviation assembly clamps and limits the material, thereby adjusting the conveying angle of the material. After the guiding roller 108 contacts the material, it rotates outside the rotating rod 107, preventing the material from shifting during conveying and effectively avoiding friction between the material and the guiding roller 108. The cutting member performs a cutting operation on the conveyed material. This method can effectively solve the problems that the material needs to be manually pushed by the operator and there is a risk of friction damage to the material during pushing.

[0026] Using a cutting device for plastic PVC processing in this embodiment, by setting the fixed frame 102, two placement plates 103, the anti-deviation component and the drive component, when specifically in use, the connection frame 106 is connected to the adjustment mechanism 104 through the sliding block 105, the adjustment mechanism 104 is adjusted according to the size of the material, so that the connection frame 106 pushes the guide roller 108 to adjust the operation position. Place the plastic material above the conveyor belt. The conveyor motor 115 drives the drive roller 116 to rotate, and drives the rolling roller 117 to rotate accordingly through the conveyor belt 118. The conveyor belt 118 conveys the material. The drive rod 111 drives the moving block 112 to move, and the connecting block 113 drives the adjusting plate 114 to clamp the material, thereby straightening the conveying direction of the material. When the material passes through the guide roller 108, the guide roller 108 rotates on the outside of the rotating rod 107, preventing the material from deviating during transportation and effectively avoiding friction between the material and the guide roller 108. The material is conveyed into the extension frame 119, and the cylinder 120 pushes the cutting knife 121 downward, so that the cutting knife 121 cuts the material. In this way, the conveying and cutting operations of the plastic material can be automatically completed, and friction between the material and the equipment during transportation can be effectively avoided, preventing damage to the plastic material due to friction.
