Description

Technical Field

[0001] This utility model relates to the field of corner cutting equipment technology, specifically a multi-station corner cutting machine for pearl cotton. Background Technology

[0002] Pearl cotton (EPE) is a material widely used in packaging, cushioning and other fields. Corner cutting is a key step in the production process. Traditional pearl cotton corner cutting machines are mostly single-station designs, requiring frequent manual loading and unloading, resulting in low production efficiency.

[0003] A search revealed a patent, CN211941052U, which discloses a multi-station corner-cutting machine for pearl cotton. The machine includes a frame; a processing area in the middle of the frame; guide rails on the frame above the processing area; two guide rails arranged symmetrically; multiple corner-cutting devices connected and controlled by transmission chains and connecting plates on the guide rails; a transmission rack cooperating with the corner-cutting devices on the inner side of the guide rails; a movable feeding plate on one side of the processing area; a material conveying device on the other side of the processing area; a material frame cooperating with the material conveying device on one side; and a control box on one side wall of the frame. This invention achieves the corner-cutting process of pearl cotton material through the coordinated movement control of the guide rails and corner-cutting devices, feeding by the feeding plate, and discharging by the material conveying device. Multiple corner-cutting devices operate synchronously, improving production efficiency, reducing product defect rates, and promoting enterprise development.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a process of cutting corners on EPE foam using several corner-cutting devices on the frame. However, in reality, due to the wide range of applications of EPE foam, its finished product is generally rectangular, requiring corner cutting according to packaging needs. All four corners of the EPE foam need to be cut. The aforementioned comparative document can only cut corners on smaller pieces of EPE foam, not larger pieces, thus reducing the applicability of this method. Therefore, there is an urgent need in the art to improve the multi-station corner-cutting machine for EPE foam to overcome the shortcomings of the existing technology. Utility Model Content

A moving disk 10 is fixedly installed at the lower output end of the fourth drive motor 14. A first sliding block 15 is fixedly installed at both ends of the moving frame 6. A first sliding groove 16 adapted to one end of the first sliding block 15 is opened at the lower part of the connecting seat 5. A first drive screw 17 with one end fixedly installed to the output end of the first drive motor 7 is rotatably connected in the first sliding groove 16. The first drive screw 17 passes through the first sliding block 15 and is threadedly connected to it. A second sliding block 18 is fixedly installed at both ends of the moving plate 8. A second sliding groove 19 adapted to the second sliding block 18 is opened on the opposite side wall inside the moving frame 6. A second drive screw 20 with one end fixedly installed to the output end of the second drive motor 9 is rotatably connected in the second sliding groove 19. The second drive screw 20 passes through the second sliding block 18 and is threadedly connected to it.

[0034] Specific implementation method in this embodiment: When it is necessary to chamfer the corners of the pearl cotton, if the area of ​​the pearl cotton is small, such as... Figure 1As shown, a piece of pearl cotton is placed in a set of positioning units. Simultaneously, several telescopic devices 3 are activated. The telescopic ends of the telescopic devices 3 drive the positioning plates 4 to move, and the positioning plates 4 clamp the pearl cotton in place. Two synchronous first drive motors 7 are activated. The output ends of the first drive motors 7 drive the first drive screw 17 to rotate. When the first drive screw 17 rotates, it drives the first sliding block 15 to slide within the first sliding groove 16. The two first sliding blocks 15 drive the moving frame 6 to move to the side of the clamped pearl cotton, with the moving disk 10 positioned directly above the pearl cotton. Two synchronous second drive motors 9 are activated. The output ends of the second drive motors 9 drive the second drive screw 20 to rotate. When the second drive screw 20 rotates, it drives the second sliding block 18 to move within the second sliding groove 19. Simultaneously, the second sliding block 18 moves, driving the moving plate 8 to move. The moving plate 8 drives the moving disk 10 to move downwards, and the moving disk 10 drives the corner-cutting blade 12 to move downwards, cutting the pearl cotton at different angles. While cutting the pearl cotton, the operator places another piece of pearl cotton that needs to be cut at different angles in another set of positioning units and clamps and fixes it with the positioning plate 4. Then, the moving frame 6 is moved again. By using at least two sets of positioning units, multi-station corner cutting of pearl cotton is achieved, improving the efficiency of corner cutting. At the same time, by turning on the fourth drive motor 14, the output end of the fourth drive motor 14 drives the moving disk 10 to rotate, which can adjust the position of several corner-cutting blades 12, enabling corner cutting of pearl cotton at different angles. When it is necessary to cut larger pieces of pearl cotton, such as... Figure 2 As shown, by removing two symmetrical fixing seats 2, a large piece of pearl cotton is clamped between multiple positioning units. The corresponding corner cutting blade 12 is removed, and the corners of the pearl cotton can be cut by the movable frame 6. With the above settings, corners can be cut on smaller pieces of pearl cotton as well as larger pieces of pearl cotton, thus improving the applicability of corner cutting pearl cotton.

[0037] The specific implementation method in this embodiment is as follows: By turning on the third drive motor 13, the output end of the third drive motor 13 drives one of the gears 22 to rotate. This gear 22 drives the ring gear 21 to rotate. When the ring gear 21 rotates, it drives several other gears 22 to rotate synchronously. The several gears 22 simultaneously drive the moving rack plate 11 to move. The moving rack plate 11 drives the corner cutting blade 12 to move. The position of several corner cutting blades 12 can be adjusted to adapt to different sizes of pearl cotton for corner cutting. By rotating the adjusting threaded rod 25, the adjusting threaded rod 25 drives the third sliding block 23 to move in the third sliding groove 24. The corner cutting blade 12 is fixedly installed on the side of the third sliding block 23 by fasteners and the first fixing block 27. When the third sliding block 23 moves, it drives the corner cutting blade 12 to move, adjusting the position of several corner cutting blades 12.
