During the unloading process, the tempered film edge material and the tempered film finished product are often mixed together. In this way, it is necessary to manually select and separate the tempered film edge material and the tempered film finished product later, which will increase the operation trouble.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0031] like Figure 1-5 As shown, in this embodiment, it includes a frame 1 and a workbench 2, the workbench 2 is fixed to the left side of the top end of the frame 1, a groove 7 is opened on the right side of the workbench 2, a die-cutting table 8 is fixed in the groove 7, four first adsorption chambers 9 are opened inside the workbench 2 and are all located outside the groove 7, a plurality of first adsorption holes 10 are opened around the right side of the workbench 2, a first vacuum adsorption assembly is provided on the left side of the workbench 2, the vacuum adsorption assembly includes a first vacuum pump 4, a vacuum pipe 5 and four suction pipes 6, the first vacuum pump 4 is fixed to the left wall inside the frame 1, the vacuum pipe 5 is connected to the vacuum port of the first vacuum pump 4, the suction pipes 6 are all connected to the right side of the vacuum pipe 5, and the four suction pipes 6 are connected to the four first adsorption chambers 9 one by one.

[0032] When the device is used to die-cut the tempered film material, the first vacuum pump 4 is started first. The first vacuum pump 4 will suck air through the vacuum pipe 5, the suction pipe 6, the first adsorption chamber 9 and the first adsorption hole 10, so that the tempered film material to be die-cut is attached to the right side of the workbench 2 and the die-cutting table 8. Combined with the work of the first vacuum adsorption component, that is, the first adsorption hole 10 will suck the tempered film material when sucking air, which is conducive to stably adsorbing the tempered film material on the right side of the workbench 2 and the die-cutting table 8, so as to perform die-cutting processing through the frame-type die-cutting knife 3.

[0033] like Figure 2 , 6 As shown in Figure 7, in this embodiment, a frame-type die-cutting knife 3 is provided on the right side of the die-cutting table 8, and spring return rods 12 are fixed on the periphery of the frame-type die-cutting knife 3. The left ends of the spring return rods 12 are connected to the limiting pressure plate 13. An adsorption table 11 is provided on the left end of the inner side of the frame-type die-cutting knife 3, and a hydraulic cylinder 21 is fixed on the right inner wall of the frame 1. The right side of the frame-type die-cutting knife 3 is connected to the power end of the hydraulic cylinder 21, and the spring return rod 14 is connected between the right side of the adsorption table 11 and the inner right wall of the frame-type die-cutting knife 3.

[0034] When the tempered film material is die-cut by the frame-type die-cutting knife 3, the extension of the hydraulic cylinder 21 drives the frame-type die-cutting knife 3 to the left and approach the die-cutting table 8. In this process, the limiting pressure plate 13 and the adsorption platform 11 will first press on the right side of the tempered film material, thereby pressing and limiting the tempered film material on the workbench 2 and the die-cutting table 8. When the frame-type die-cutting knife 3 continues to move to the left and enters the groove 7, the frame-type die-cutting knife 3 will cut the tempered film material. At the same time, the limiting pressure plate 13 will compress the spring return rod 12, and the adsorption platform 11 will compress the spring return rod 14 and the telescopic tube 16. Therefore, the tempered film material is flattened by the cooperation of the limiting pressure plate 13 and the adsorption platform 11, so as to avoid the occurrence of warping of the tempered film material during the die-cutting process, thereby effectively ensuring the quality of the finished tempered film after die-cutting.

[0035] like Figure 2-6 As shown, in this embodiment, the frame-type die-cutting knife 3 is provided with a second vacuum adsorption component, and the second vacuum adsorption component includes a second vacuum pump 15, a telescopic tube 16 and two spring return rods 14. The second vacuum pump 15 is fixed to the inner right wall of the frame-type die-cutting knife 3, and one end of the telescopic tube 16 is connected to the vacuum port of the second vacuum pump 15. A second adsorption cavity 17 is opened in the adsorption platform 11, and a plurality of second adsorption holes 18 communicating with the second adsorption cavity 17 are opened on the left side of the adsorption platform 11. The other end of the telescopic tube 16 is connected to the second adsorption cavity 17. The spring return rod 14 is connected between the right side of the adsorption platform 11 and the inner right wall of the frame-type die-cutting knife 3. A first material receiving box 19 is provided below the workbench 2, and a second material receiving box 20 is provided below the frame-type die-cutting knife 3.

[0036] After the tempered film material is die-cut, the tempered film edge material and the tempered film finished product are produced. Since the operation of the first vacuum adsorption component will make the first adsorption hole 10 inhale air, the tempered film edge material will be adsorbed on the right side of the workbench 2 by the first adsorption hole 10, and the second vacuum pump 15 works, and the second vacuum pump 15 inhales air through the telescopic tube 16, the second adsorption chamber 17 and the second adsorption hole 18. At this time, the second adsorption hole 18 adsorbs the die-cut tempered film finished product on the left side of the adsorption platform 11, and then the hydraulic cylinder 21 contracts and drives the frame-type die-cutting knife 3 to move to the right and reset. In this process, the tempered film edge material continues to be adsorbed on the right side of the workbench 2, and the tempered film finished product moves to the right with the adsorption platform 11, so the adsorption platform 11 moves with After the frame-type die-cutting knife 3 is away from the workbench 2, it is convenient to quickly separate the tempered film edge material from the tempered film finished product, and then the first vacuum pump 4 and the second vacuum pump 15 are turned off, and the first adsorption hole 10 no longer adsorbs the tempered film edge material on the side of the workbench 2, so the tempered film edge material will automatically fall into the first receiving box 19 for collection, and the second adsorption hole 18 no longer adsorbs the tempered film finished product, so the tempered film finished product will automatically fall into the second receiving box 20 for collection. In summary, it is convenient to quickly separate the tempered film edge material from the tempered film finished product and unload it, avoiding the mixing of the tempered film edge material and the tempered film finished product during the unloading process, thereby eliminating the need to manually select and separate the tempered film edge material and the tempered film finished product at a later stage. While unloading is convenient, it also effectively reduces the trouble of operation.

[0037] like Figure 3 , 6 As shown, in this embodiment, the distance between the outer wall of the die-cutting table 8 and the inner wall of the groove 7 is equal to the thickness of the frame-type die-cutting knife 3, the right side surface of the workbench 2 is flush with the right side surface of the die-cutting table 8, the adsorption table 11 extends to the left of the frame-type die-cutting knife 3, and the left side surface of the adsorption table 11 is flush with the left side surface of the limiting pressure plate 13.

[0038] Since the right side of the workbench 2 is flush with the right side of the die-cutting table 8, and the left side of the adsorption table 11 is flush with the left side of the limiting pressing plate 13, it is beneficial to ensure the flatness of the finished tempered film after die-cutting.

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementation schemes of the present invention. In addition, other implementation schemes are also included. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
