Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 - 5 shown, an embodiment of a high-speed die-cutting machine with automatic feeding and positioning provided in this embodiment.

[0025] A high-speed die-cutting machine with automatic feeding and positioning, including a die-cutting machine body 1. A unwind feeding roller 2 and a rewind feeding roller 3 are respectively arranged on both sides of the die-cutting machine body 1. A positioning mechanism 4 is arranged on the die-cutting machine body 1. The positioning mechanism 4 includes a fixed frame 5 fixedly installed on the die-cutting machine body 1. A bidirectional lead screw 6 is movably installed inside the fixed frame 5. A motor connected to the bidirectional lead screw 6 is fixedly installed on one side of the fixed frame 5. Two moving blocks 7 are symmetrically and movably installed on the bidirectional lead screw 6. A support frame 8 is fixedly installed on the top of the moving block 7. A positioning block 9 is fixedly installed on the inner wall of the support frame 8. Two rollers 10 are arranged on one side of the positioning block 9. Through the setting of the positioning mechanism 4, materials with different width specifications can be corrected and limited. Before feeding the die-cutting material on the unwind feeding roller 2, first pull one end of the material and connect it to the rewind feeding roller 3. At this time, the material is between the two support frames 8. Then start the motor to drive the bidirectional lead screw 6 to rotate, and it drives the two support frames 8 to move through the moving blocks 7 until the positioning blocks 9 on the inner walls of the two support frames 8 fit on both sides of the material, which not only corrects and limits the material but also positions it in the feeding direction. And the two rollers 10 in the support frame 8 press on the surface of the material, assisting the positioning block 9 to position and preventing wrinkles from occurring during feeding. Subsequently, start the unwind feeding roller 2 and the rewind feeding roller 3 to feed the material, so that the material is accurately positioned and conveyed on the die-cutting machine body 1, effectively avoiding deviation in the feeding position of the material and preventing the quality of die-cutting from being affected.

[0026] As Figures 1 - 5 shown, a rubber pad 11 is fixedly sleeved on the roller 10. Two electric telescopic rods 12 are symmetrically installed inside the support frame 8. A fixed block 13 connected to the output end of the electric telescopic rod 12 is fixedly installed on the roller 10. Two support plates 14 are symmetrically installed on one side of the unwind feeding roller 2. A cleaning brush 15 is arranged between the two support plates 14. Through the setting of the rubber pad 11, the friction force on the surface of the roller 10 can be increased, the pressing force of the roller 10 on the material can be improved, and at the same time, the material can be protected from wear. Through the setting of the electric telescopic rod 12 and the fixed block 13, start the electric telescopic rod 12 to make its output end stretch and retract, and the distance between the two rollers 10 can be adjusted to facilitate the use of materials with different thicknesses. Through the setting of the support plate 14 and the cleaning brush 15, after the material is placed on the unwind feeding roller 2, the cleaning brush 15 fits on the surface of the material, and the cleaning brush 15 can clean the surface of the material during the feeding process.

[0027] As Figure 1 、 Figure 4 and Figure 5As shown in the figure, a chute 16 is formed in the support plate 14. A support block 17 connected to the cleaning brush 15 is slidably installed inside the chute 16. A first spring 18 connected to the chute 16 is fixedly installed on one side of the support block 17. Two second springs 19 are symmetrically installed inside the support block 17. One end of the second spring 19 is fixedly installed with a clamping rod 20. Clamping blocks 21 are fixedly installed on both sides of the cleaning brush 15. A plurality of limiting grooves engaged with the clamping rod 20 are formed in the clamping blocks 21. One end of the clamping rod 20 is arc-shaped. Through the arrangement of the chute 16, the support block 17 and the first spring 18, since the support block 17 is connected to the cleaning brush 15 and the support block 17 slides in the chute 16, the cleaning brush 15 can move between the two support plates 14. Also, because a first spring 18 is connected between the support block 17 and the chute 16, the cleaning brush 15 can achieve the function of gradually moving, so as to facilitate continuous contact with the material on the unwinding and feeding roller 2 as the feeding of the material decreases, to ensure continuous cleaning. Through the arrangement of the second spring 19, the clamping rod 20 and the clamping block 21, the cleaning brush 15 and the support block 17 are connected through the contact of the clamping rod 20 and the clamping block 21. The clamping rod 20 is supported by the second spring 19 and one end is clamped in the limiting groove in the clamping block 21 to fix the cleaning brush 15 installed on the two support blocks 17 and improve its firmness. At the same time, one end of the clamping rod 20 is arc-shaped, so that the clamping blocks 21 on both sides of the cleaning brush 15 can easily squeeze the clamping rod 20 to make it contract and separate from the limiting groove, thus facilitating the disassembly and replacement of the cleaning brush 15.

[0028] In this embodiment, as Figures 1 - 5 shown, the working process of a high-speed die-cutting machine with automatic feeding and positioning provided in this embodiment is as follows:

[0029] Before feeding the die-cutting material on the unwinding and feeding roller 2, first pull one end of the material and connect it to the winding and feeding roller 3. At this time, the material is between the two support frames 8. Then start the motor to drive the bidirectional lead screw 6 to rotate, so that it drives the two support frames 8 to move through the moving block 7 until the positioning blocks 9 on the inner walls of the two support frames 8 are attached to both sides of the material, which not only corrects and limits the material but also plays a role in positioning in the feeding direction. And the two rollers 10 in the support frame 8 press on the surface of the material to assist the positioning block 9 in positioning and prevent wrinkles from occurring during feeding. Subsequently, start the unwinding and feeding roller 2 and the winding and feeding roller 3 to feed the material, so that the material is accurately positioned and conveyed on the die-cutting machine body 1, effectively avoiding deviation in the feeding position of the material.

[0030] In summary, in this embodiment, for a high-speed die-cutting machine with automatic feeding and positioning according to this embodiment, through the setting of the rubber pad 11, the friction force on the surface of the roller 10 can be increased, the pressing force of the roller 10 on the material can be enhanced, and at the same time, the material can be protected from wear. Through the setting of the electric telescopic rod 12 and the fixed block 13, when the electric telescopic rod 12 is started to make its output end extend and retract, the distance between the two rollers 10 can be adjusted to conveniently adapt to materials of different thicknesses. Through the setting of the support plate 14 and the cleaning brush 15, after the material is placed on the unwind feeding roller 2, the cleaning brush 15 adheres to the surface of the material, and the cleaning brush 15 can clean the surface of the material during the feeding process. Through the setting of the chute 16, the support block 17 and the first spring 18, since the support block 17 is connected to the cleaning brush 15 and the support block 17 slides in the chute 16, the cleaning brush 15 can move between the two support plates 14. Also, because a first spring 18 is connected between the support block 17 and the chute 16, the cleaning brush 15 can realize the function of gradually moving, so as to conveniently keep adhering to the material on the unwind feeding roller 2 as it is fed, to ensure continuous cleaning. Through the setting of the second spring 19, the clamping rod 20 and the clamping block 21, the cleaning brush 15 and the support block 17 are connected through the contact of the clamping rod 20 and the clamping block 21. The clamping rod 20 is supported by the second spring 19 and one end of it is clamped in the limiting groove in the clamping block 21 to fix the cleaning brush 15 installed on the two support blocks 17 and improve its firmness. At the same time, one end of the clamping rod 20 is set to be arc-shaped, so that the clamping blocks 21 on both sides of the cleaning brush 15 can conveniently squeeze the clamping rod 20 to make it contract and separate from the limiting groove, thus facilitating the disassembly and replacement of the cleaning brush 15.
