Description

Technical Field

[0001] The utility model relates to the technical field of edge material recovery, in particular to an edge material recovery mechanism for a PVC hard sheet production line. Background Art

[0002] Hard sheet, also known as film, is a sheet material used for blister packaging. The sheet with a thickness greater than 2mm is called a plate. Commonly used ones are: PET (polyethylene terephthalate) hard sheet, PVC (polyvinyl chloride) hard sheet, PS (polystyrene) hard sheet, and ABS (engineering plastic). PS hard sheet has low density, poor toughness, and is easy to burn. When it burns, it will produce styrene gas (a harmful gas), so it is generally used to produce various industrial blister trays. PVC hard sheet has moderate toughness and is not easy to burn. When it burns, it will produce chlorine gas, which has a certain impact on the environment. PVC is easy to heat-seal and can be sealed with a sealing machine and a high-frequency machine. It is the main raw material for the production of transparent blister products. PVC hard sheet needs to be cut during production to get the right size, and a lot of edge materials will be produced after cutting. If these edge materials are simply collected and placed, it will take up more space. Generally, they are manually compressed by staff, and the degree of manual compression is low. Moreover, when collecting edge materials, they cannot be collected quantitatively, which makes it inconvenient to maintain the compressed body shape.

[0003] And in the application document with publication number CN211334704U, a side material recovery mechanism of a PVC rigid sheet production line is mentioned. The device falls onto the receiving plate through the feed hopper, and the double-axis motor drives the fixed shaft to rotate, and the fixed shaft drives the second bevel gear to rotate, and the second bevel gear drives the first bevel gear meshing with it to rotate, and the first bevel gear drives the rotating shaft to rotate, and the rotating shaft drives the receiving plate to rotate. When the receiving plate rotates counterclockwise, it receives the material and puts the material on the guide block, and the side material slides from the guide block into the compression box. At the same time, the double-axis motor also drives the fourth bevel gear to rotate, and the fourth bevel gear drives the third bevel gear meshing with it to rotate, and the third bevel gear drives the threaded tube to rotate, and the rotation of the threaded tube drives the reciprocating screw rod up and down. The reciprocating screw drives the top plate to move, and the top plate drives the fixed column to move, and the fixed column drives the extrusion block to move up and down. The extrusion block extends into the compression box to compress the edge material, thereby realizing automatic compression and lifting. The compressed edge material is pushed out of the compression box by the push rod motor to drive the push plate, so that the received materials are equal, thereby ensuring the consistency of the size after compression. The whole device is not only convenient for quantitative material receiving, but also can compress automatically. The feeding and compression are realized by the same driving mechanism, which reduces the cost of the equipment and is suitable for market promotion. However, there are still certain defects that need to be optimized. The specific defects are as follows: Since the cut edge materials are of different sizes, the edge materials are not pre-treated inside the feed hopper and are easy to get stuck, reducing the processing efficiency.

[0004] Therefore, it is particularly important to design a side material recovery mechanism for a PVC rigid sheet production line to change the above technical defects and improve overall practicality. Utility Model Content
