Description

Technical Field

[0001] The utility model relates to the technical field of PVC sheet processing, in particular to a PVC sheet cutting device. Background Art

[0002] VC sheets are often cut during the manufacturing and use process. The traditional cutting method is for workers to cut with a handheld cutting machine. During the cutting process, hand shaking can easily cause poor linearity of the cutting. At the same time, the sheet needs to be fixed during the cutting process, and the VC sheet needs to be transported and loaded.

[0003] For example, a PVC sheet cutting device disclosed in publication number CN216917942U can drive the clamping block to move upward by moving the connecting rod upward, so that the clamping block no longer limits the top of the conveying roller, and then the top of the conveying tube can be moved to the left through the hinge, thereby solving the problem that it is troublesome to reset the existing PVC sheet when it is fixed on the conveying roller.

[0004] However, the above-mentioned cutting structure is transported by conveyor rollers during loading. Since the VC sheet is prone to shaking when moving on the surface of the conveyor roller, the VC sheet is not in a centered state when it reaches the cutting point, thereby affecting the processing efficiency. In view of this, we propose a PVC sheet cutting device. Utility Model Content

[0005] The purpose of the utility model is to provide a PVC sheet cutting device to solve the problems raised in the above background technology.

[0006] The cam is provided with a U-shaped frame fixedly mounted on the upper end of the conveying structure, and slide grooves are provided on both sides of the upper end of the U-shaped frame, and slide grooves are provided on the inner wall of the slide grooves for sliding connection. Two groups of rotating rods are respectively rotatably connected to the two sides of the upper end of the conveying structure, and a sleeve is fixedly installed on the surface of the rotating rod, and a positioning plate is fixedly installed on the side wall of the sleeve. The upper end of the U-shaped frame is rotatably connected to the screw sleeve, and the connecting cylinder is threadedly connected to the screw surface. One end of the connecting rod is hinged on the two sides of the connecting cylinder, and the other end of the connecting rod is hinged on the side wall of the slider. A support rod passes through the lower end of the slider, and one end of the support rod contacts the side wall of the positioning plate. A support plate is fixedly installed on the surface of the other end of the support rod, and a buffer spring is wound around the surface of the support rod, and a pressing structure is provided inside the positioning plate.

[0007] Preferably, the clamping structure includes a directional cylinder penetrating the inner wall of the positioning plate, a moving rod is slidably connected inside the directional cylinder, a contact plate is fixedly installed on one end of the moving rod, a limiting plate is fixedly installed on the other end of the moving rod, a connecting block is slidably connected to the side wall of the positioning plate, a clamping plate is fixedly installed on the lower end of the connecting block, one end of the hinged rod is hinged to the upper end of the connecting block, the other end of the hinged rod is hinged to the side wall of the contact plate, a return spring is arranged on the surface of the moving rod, and the lower end of the limiting plate is fixedly connected to the upper end of the support rod.

[0008] Preferably, a guide groove is formed on the side wall of the positioning plate, one end of a guide rod is slidably connected to the inner wall of the guide groove, and the other end of the guide rod is fixedly connected to the side wall of the support rod.

[0009] Preferably, one end of the return spring is fixedly connected to the side wall of the directional cylinder, and the other end of the return spring is fixedly connected to the side wall of the contact plate.

[0010] Preferably, a handle is fixedly mounted on the upper end of the screw rod.

[0011] Preferably, the length of the slide groove is adapted to the moving trajectory of the support rod.

[0012] Compared with the prior art, the utility model provides a PVC sheet cutting device having the following features:

[0013] Beneficial effects:

[0014] 1. The PVC sheet cutting device is provided with a positioning structure so as to facilitate the positioning and protection of the PVC sheet during feeding. When the PVC sheet moves, its side wall will contact the positioning plate, so that it is positioned to expand outward. At the same time, the movement of the positioning plate will drive the support rod to move and stretch the buffer spring. The PVC sheet is positioned and moved by the elastic force of the buffer spring. The user can adjust the height of the connecting tube to adjust the initial position of the two sets of positioning plates, so as to avoid the VC sheet being not in a centered state when it reaches the cutting point later, thereby improving the processing efficiency.

[0015] 2. The PVC sheet cutting device is provided with a clamping structure so as to facilitate the clamping and fixing of the PVC sheet moved to the cutting table body. When the positioning plate drives the support rod to move, the support rod will drive the limit plate and the moving rod at its upper end to move. The movement of the moving rod drives the contact plate to move, and then drives the clamping plate to move downward to contact and fix with the upper end of the PVC sheet, thereby avoiding shaking during the subsequent PVC sheet cutting process.
