Description

Technical Field

[0001] The utility model relates to the technical field of PVC sheet production, and particularly relates to a collecting device for preventing breakage of PVC sheets during extrusion. Background Art

[0002] PVC sheet is a plastic sheet made of polyvinyl chloride, which has high hardness, wear resistance, chemical corrosion resistance, fire retardancy and excellent electrical insulation performance. It is widely used in the fields of construction, advertising, packaging, electronic appliances, etc. There are both rigid ones for building and industrial parts, and soft ones for packaging and hoses, etc. PVC sheet has good processing performance and can be recycled, and it is a multi-functional environmental protection material.

[0003] The Chinese patent discloses a conveying device for preventing breakage of PVC sheets during extrusion (publication number: CN220428449U). This device realizes the shearing of scraps at the corners of PVC sheets through structures such as the first conveyor belt body, the first motor, the threaded column, the fixing plate, the telescopic rod, the roller box, the positioning roller, etc. During the conveying process, the sheets are placed neatly without manual straightening, improving the conveying effect. However, the above device still has the following problems:

[0004] The above device conveys PVC sheets through a conveyor belt. When the PVC sheets deviate too much during the conveying process, the end side of the PVC sheet may directly hit the roller box, resulting in damage to the PVC sheet. Moreover, the deviation correction devices on both sides of the conveyor belt of the above device are respectively controlled by two motors, which are not easy to adjust synchronously by the motors. As a result, the PVC sheets are not easy to be centered on the conveyor belt, and the structure driven by two motors has a high cost. In addition, although the above device winds up the PVC sheets through a winding shaft, which facilitates the collection of PVC sheets by the operator, it is rather troublesome when the PVC sheets are separated from the winding shaft.

A conveyor belt 102 is installed in the middle of the first base 101 and below the rotating roller 104. The deviation rectifying mechanism 2 further includes a second base 201. The second bases 201 are distributed on both sides of the conveyor belt 102. A top frame 202 is fixedly installed on the tops of the two second bases 201 on both sides. The middle of the top frame 202 extends above the conveyor belt 102. One side of the top of the top frame 202 is fixedly installed with the motor 203. The output shaft of the motor 203 is fixedly connected to a second screw rod 204. Threads are respectively arranged on both sides of the surface of the second screw rod 204, and the threads on both sides of the surface of the second screw rod 204 are in opposite directions.

When the end of the sheet passes the inner side of the rotating plate 211, it is pushed by the deflection correction wheel 212 to be centered. After the sheet enters under the support plate 111, the motor 103 drives the rotating roller 104 and the side support plate 111 to rotate. After the end of the sheet is bound to the surface of the support plate 111, the sheet is gradually wound and rolled on the surface of the support plate 111.
