Description

Technical Field

[0001] The utility model belongs to the technical field of die-cutting machines, and in particular relates to a die-cutting machine sorting structure and a die-cutting machine. Background Art

[0002] Die-cutting is the process of forming specific parts and components from raw materials through precision machining and cutting according to predetermined shapes. Die-cutting is achieved through processes such as compounding, die-cutting, rejecting defective products, and slicing. Among them, rejecting defective products is very important in the whole process. Existing paper processing die-cutting machines mostly use air blowing devices to reject defective products. Each time the air blowing device blows, it can only blow off one defective product from the main material belt and reject it. When multiple defective products appear quickly and continuously on the main material belt of a high-speed die-cutting machine, the air blowing device with low rejection efficiency is likely to cause defective products to be missed, resulting in uncontrollable product quality and the easy production of defective products.

DETAILED DESCRIPTION

[0021] Combined with reference Figure 1-4 The present embodiment provides a high-speed die-cutting machine, including a first main material belt 51, a second main material belt 53, a defective product detection device 6, a controller, a die-cutting machine sorting structure, and a waste conveyor belt 7 for receiving defective products on the sorting flap 3. Paper products 8 are transported from the first main material belt 51 to the second main material belt 53. The defective product detection device 6 is a CCD camera. The defective product detection device 6 is arranged above the first main material belt 51 and is electrically connected to the controller to detect defective products. The controller is electrically connected to the drive motor 11 to control the drive motor 11 to rotate a specific angle, thereby rotating the sorting flap 3 in the die-cutting machine sorting structure to the feeding side of the waste conveyor belt 7.

[0022] In this embodiment, the die-cutting machine sorting structure is as follows Figure 1-3As shown, it includes a turntable drive structure, a connecting rod transmission structure and a sorting flap 3. The turntable drive structure includes a drive motor 11 fixed to the die-cutting machine frame 4 and a turntable 15 fixedly connected to the output shaft 113 of the drive motor 11, wherein the drive motor 11 is a servo motor. The connecting rod transmission structure includes a connecting rod 21 and a rotating bracket 23. One end of the connecting rod 21 is rotatably connected to the turntable transmission shaft 151 protruding from the turntable 15 through a rotating pair 1 25. The other end of the connecting rod 21 extends a connecting rod transmission shaft 211. The connecting rod transmission shaft 211 is rotatably connected to the upper half of the rotating bracket 23 through a rotating pair 27. One end of the sorting flap 3 is rotatably connected to the lower half of the rotating bracket 23 through a rotating pair 3 29. The other end of the sorting flap 3 is rotatably connected to the die-cutting machine frame 4 through a rotating pair 4 31. The sorting flap 3 is connected so that it can rotate relative to the die-cutting machine frame 4 under the drive of the connecting rod 21. The sorting flap 3 is located between the first main material belt 51 and the second main material belt 53, which are in the same conveying direction and independent of each other. The end of the sorting flap 3 connected to the die-cutting machine frame 4 receives the products conveyed by the first main material belt 51. The spacing between the first main material belt 51 and the second main material belt 53 and the length of the sorting flap 3 are set to match the length of the paper products 8, in order to ensure that the sorting flap 3 will not mislead the qualified paper products 8 to the waste conveyor belt 7. In addition, when the defective product detection device 6 does not detect defective products on the first main material belt 51, the sorting flap 3 rotates to be in the same plane as the first main material belt 51 and the second main material belt 53.

[0023] In this embodiment, the first rotating pair 25, the second rotating pair 27, the third rotating pair 29 and the fourth rotating pair 31 are all rolling bearing type rotating pairs. The rotation axis of the turntable 15, the rotation axis of the rotatable connection between the turntable 15 and the connecting rod 21, the rotation axis of the rotatable connection between the connecting rod 21 and the rotating bracket 23, the rotation axis of the rotatable connection between the rotating bracket 23 and the sorting flap 3, and the rotation axis of the rotatable connection between the sorting flap 3 and the die-cutting machine frame 4 are all parallel to each other.

[0024] The defective product sorting principle of the high-speed die-cutting machine of this embodiment is that the CCD camera (i.e., the defective product detection device 6) sends the defective product data on the first main material belt 51 detected to the controller, and the controller controls the output shaft 113 of the servo motor (i.e., the drive motor 11) to rotate half a circle counterclockwise according to the received defective product data, so that the turntable 15 moves from Figure 1 Turn counterclockwise to the indicated position Figure 4 In the position shown, the turntable drive shaft 151 drives the connecting rod 21 to move, and then the connecting rod 21 drives the sorting flap 3 to move from Figure 1 Rotate the position shown to Figure 4In the position shown, the sorting flap 3 rotates to the feeding side of the waste conveyor belt 7, and guides the defective products to the waste conveyor belt 7 for removal. When the paper products 8 on the first main material belt 51 detected by the CCD camera have no defective products, the controller controls the output shaft 113 of the servo motor to continue to rotate half a circle counterclockwise according to the received paper product data, so that the turntable 15 moves from Figure 4 Turn counterclockwise to reset the position shown Figure 1 In the position shown, qualified paper products 8 are transported from the first main material belt 51 to the second main material belt 53 via the sorting flap 3 .

[0025] In other embodiments, a separate sorting conveyor belt may be provided on the sorting flap 3, and the conveying direction of the sorting conveyor belt may be consistent with the first main material belt 51 and the second main material belt 53, so as to speed up the conveyance of defective products on the sorting flap 3 and improve the overall sorting efficiency.

[0026] In other embodiments, the rotatable connection between the connecting rod 21 and the rotating bracket 23, the rotatable connection between the rotating bracket 23 and the sorting flap 3, and the rotatable connection between the sorting flap 3 and the die-cutting machine frame 4 can also be hinged. The defective product detection device 6 can also be a Lingyun optical detection instrument.

[0027] In other embodiments, an air blowing device for blowing defective products to the waste conveyor belt 7 may be further provided between the second main material belt 53 and the sorting flap 3. When the defective product detection device 6 detects that only a single defective product appears non-continuously on the first main material belt 51, the controller only needs to control the air blowing device to blow the single defective product to the waste conveyor belt 7 without rotating the sorting flap 3, which is conducive to saving defective product sorting costs.

[0028] The die-cutter sorting structure and die-cutter of the utility model realize the sorting and rejection of defective products on the die-cutter through mechanical transmission among a driving motor, a turntable, a connecting rod, a rotating bracket and a sorting flap. Compared with the existing air blowing device, the defective product sorting and rejection effect is better. When multiple defective products appear quickly and continuously on the main material belt, the defective products can be effectively avoided from being missed, the product quality can be better controlled, the yield rate can be improved, and the structure is simple and easy to maintain.
