Description

Technical Field

[0001] This utility model relates to the field of film slitting equipment technology, and in particular to a plastic film production equipment with waste recycling function. Background Technology

[0002] Plastic film slitting and rewinding is a process in which a large roll of film is slitting longitudinally into several narrow strips of film according to the required size using a slitting machine, and then rewinding them into smaller rolls. Therefore, slitting and rewinding allows film specifications to be adapted to different production scenarios.

[0003] When slitting and rewinding film, if a large roll of film needs to be slit into different width specifications, the equipment needs to position the cutting line according to the target width. At this time, the difference between the original film width and the target width will be cut off as waste edge. Therefore, it is necessary to recycle the excess waste edge during the slitting operation. However, the traditional waste edge recycling uses a winding roller, which is difficult to control precisely. It is easy for the waste material to be wrapped too tightly or loosely, resulting in deformation or even breakage of the recycled waste material. The manual roller changing operation is frequent and inefficient. The recycling roller capacity is limited and multiple shutdowns are required for replacement, which affects the continuity of production. Utility Model Content

[0004] The purpose of this invention is to provide a plastic film production equipment with waste recycling capabilities, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic film production device with waste recycling function includes a gearbox and a negative pressure absorption box. An unwinding mechanism is provided on one side of the gearbox and the negative pressure absorption box, and a winding mechanism is provided on the other side. A slitting mechanism is provided between the gearbox and the negative pressure absorption box. A waste edge recycling mechanism is also provided between the gearbox and the negative pressure absorption box, located above the slitting mechanism. The waste edge recycling mechanism includes multiple collecting pipes, with each collecting pipe having two sides... Each of the two manifolds is fixedly installed with a connecting flange. Two adjacent connecting flanges are fixedly connected to each other. One side of the connecting flange of each of the two manifolds is also fixedly connected to the gear power box and the negative pressure absorption box respectively. The inner cavity of the manifold is connected to the inner cavity of the negative pressure absorption box. An installation seat is also fixedly installed on the outside of the two connecting flanges. An adjusting block is movably installed on one side of the installation seat. A lifting rod is fixedly installed at the bottom of the adjusting block. A carrier plate is fixedly installed at the bottom of the lifting rod. A recovery pipe is fixedly installed on the side of the carrier plate away from the lifting rod. A dial is movably installed inside the recovery pipe.

[0007] As a further preferred embodiment of this utility model, an interface is fixedly installed at the bottom of the collecting pipe. The tubular structure composed of multiple collecting pipes can realize the negative pressure suction force diversion generated by the negative pressure absorption box, thereby realizing the recycling of multiple film waste edges.

[0008] As a further preferred embodiment of this utility model, a first mounting groove is provided on one side of the mounting base, and guide grooves are provided on both sides of the first mounting groove. A second mounting groove is provided on the other side of the mounting base. The mounting base is inserted into two connecting flanges through the second mounting groove and fixed with bolts. The mounting base can provide a mounting carrier for the adjusting block, and the opening of the first mounting groove and the guide groove can adjust the installation angle of the adjusting block.

[0009] As a further preferred embodiment of this utility model, the adjusting block is inserted into the first mounting groove and fixed by a limiting bolt.

[0010] As a further preferred embodiment of this utility model, two bearings are fixedly installed inside the recycling tube. The bearings provide a mounting base for the dial wheel and enable the dial wheel to rotate. A guide plate is also fixedly installed inside the recycling tube below the bearings. The guide plate is obliquely arranged and can guide one end of the waste edge generated during film cutting into the space between the dial wheel and the recycling tube.

[0011] As a further preferred embodiment of this utility model, the dial wheel includes a rotating shaft, with multiple blades fixedly installed on the outer side of the rotating shaft. Multiple ball bearings are rotatably installed on the outer contour of the blades. The two ends of the rotating shaft are respectively rotatably installed in one of the bearings. The dial wheel rotates after being subjected to negative pressure suction transmitted by the negative pressure absorption box through the collection pipe and the recovery pipe, which can push the waste film edge introduced into the recovery pipe into the collection pipe, thus ensuring the stability of the waste film edge recovery.

[0012] As a further preferred embodiment of this utility model, one end of the recycling tube is connected to the interface via a flexible tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by setting up a negative pressure absorption box and a waste edge recycling mechanism, the waste edges generated during film slitting and rewinding can be absorbed by the suction force of negative pressure without the need to control the tension of waste edge recycling or frequently replace the recycling roller. Therefore, the waste edge recycling efficiency can be effectively improved. In addition, a dial wheel is set in the recycling tube of the waste edge recycling mechanism, which can be rotated by the suction force of negative pressure. This, together with the guide plate, applies pressure to the film waste edges entering the recycling tube and rolls them into the collection tube, thereby improving the stability of waste edge recycling.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-5 As shown, this utility model provides a plastic film production equipment with waste recycling function, including a gear power box 1 and a negative pressure absorption box 2. An unwinding mechanism 3 is provided on one side of the gear power box 1 and the negative pressure absorption box 2, and a winding mechanism is provided on the other side. A slitting mechanism 4 is provided between the gear power box 1 and the negative pressure absorption box 2. A waste edge recycling mechanism 5 is also provided between the gear power box 1 and the negative pressure absorption box 2 above the slitting mechanism 4. The waste edge recycling mechanism 5 includes multiple collection pipes 6. Both sides are fixedly installed with connecting flanges 7, and two adjacent connecting flanges 7 are fixedly connected to each other. One side of the connecting flange 7 of the two manifolds 6 is also fixedly connected to the gear power box 1 and the negative pressure absorption box 2 respectively, and the inner cavity of the manifold 6 is connected to the inner cavity of the negative pressure absorption box 2. The outer side of the two connecting flanges 7 is also fixedly installed with mounting bases 8. An adjusting block 9 is movably installed on one side of the mounting base 8. A hanging rod 10 is fixedly installed at the bottom of the adjusting block 9. A carrier plate 11 is fixedly installed at the bottom of the hanging rod 10. A recovery pipe 12 is fixedly installed on the side of the carrier plate 11 away from the hanging rod 10. A dial 13 is movably installed inside the recovery pipe 12.

[0023] like Figures 2-3 As shown, a first mounting groove 15 is provided on one side of the mounting base 8, and guide grooves 16 are provided on both sides of the first mounting groove 15. A second mounting groove 18 is provided on the other side of the mounting base 8. The mounting base 8 is inserted into the two connecting flanges 7 through the second mounting groove 18 and fixed with bolts. The mounting base 8 can provide a mounting carrier for the adjusting block 9. The opening of the first mounting groove 15 and the guide groove 16 can adjust the installation angle of the adjusting block 9. The adjusting block 9 is inserted into the first mounting groove 15 and fixed by the limiting bolt 17.

[0024] like Figure 2 , Figures 4-5 As shown, two bearings 19 are fixedly installed inside the recycling tube 12. The bearings 19 provide a mounting base for the dial wheel 13 and enable the dial wheel 13 to rotate. A guide plate 20 is also fixedly installed inside the recycling tube 12 below the bearings 19. The guide plate 20 is obliquely arranged and can guide one end of the waste edge generated during film cutting into the space between the dial wheel 13 and the recycling tube 12. The dial wheel 13 includes a rotating shaft 21. Multiple blades 22 are fixedly installed on the outer side of the rotating shaft 21. Multiple balls 23 are rotatably installed on the outer contour of the blades 22. The two ends of the 21 are respectively rotatably installed in one of the bearings 19. The dial 13 rotates after being subjected to the negative pressure suction force transmitted by the negative pressure absorption box 2 through the collection pipe 6 and the recovery pipe 12. This pushes the waste film edge introduced into the recovery pipe 12 into the collection pipe 6, ensuring the stability of the waste film edge recovery. The bottom of the collection pipe 6 is fixedly installed with an interface 14. The tubular structure composed of multiple collection pipes 6 can realize the diversion of the negative pressure suction force generated by the negative pressure absorption box 2, thereby realizing the recovery of multiple waste film edges. One end of the recovery pipe 12 is connected to the interface 14 through a hose.

[0025] It should be noted that this utility model is a plastic film production equipment with waste recycling. During operation, the unwinding mechanism 3 releases the film, which is then cut by the slitting mechanism 4. The cut plastic film is then rewound by the winding mechanism. Waste edges are processed by the waste edge recycling mechanism 5. Multiple manifolds 6 are connected by connecting flanges 7, and their inner cavities are connected to the negative pressure absorption box 2. The negative pressure generated by the negative pressure absorption box 2 is transmitted to the recycling pipe 12 via the manifolds 6. One end of the waste edge can be placed at one end of the corresponding recycling pipe 12, thereby allowing the waste edge to pass through… The suction force generated by the negative pressure draws one end of the waste edge into the recycling pipe 12 via the guide plate 20. At this time, under the action of the negative pressure suction, the dial wheel 13 rotates. When its blade 22 rotates parallel to the port of the recycling pipe 12, several balls 23 on its outer contour come into contact with the inner wall of the recycling pipe 12, thereby pushing the waste edge to move towards the collection pipe 6. The balls 23 will then come into contact with the waste edge to ensure smooth transport of the waste edge. Afterward, the waste edge enters the collection pipe 6 through the recycling pipe 12 and the hose connected to the interface 14 and is finally introduced into the negative pressure absorption box 2 for collection.
