DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-3 As shown, the embodiment of the utility model provides a die-cutting machine stripping device, comprising:

[0024] A base 1, four supporting rods 2 are fixedly connected to the base 1, the tops of the four supporting rods 2 are fixedly connected to a mounting plate 3, the bottom end of the mounting plate 3 is fixedly connected to a cylinder 4, a die-cutting table 5 is fixedly connected to the upper surface of the base 1, a groove is provided in the die-cutting table 5, a template 6 is fixedly connected to the output end of the cylinder, and two stripping components, the component includes a guide rod 7 fixedly connected to the base 1, a No. 1 slider 8 is slidably sleeved on the guide rod 7, a slide groove is provided on the upper surface of the base 1, a No. 2 slider 9 is slidably connected in the slide groove, a No. 1 connecting rod 10 is hinged to the bottom end of the No. 1 slider 8, the bottom end of the No. 1 connecting rod 10 is hinged to the upper surface of the No. 2 slider 9, a No. 2 connecting rod 11 is fixedly connected between the two No. 1 sliders 8, a No. 3 connecting rod 12 is fixedly connected to the side wall of the No. 2 connecting rod 11, and the No. 3 connecting rod is fixedly connected to the output end of the cylinder 4 away from the end of the No. 2 connecting rod 11, and the two stripping components are symmetrically arranged about the cylinder 4, so as to remove the waste on both sides of the die-cutting table 5;

[0025] When the air intake die-cutting is working, the processed material is placed on the die-cutting table 5, and the cylinder 4 is started to drive the template 6 to die-cut the material. At the same time, the output end of the cylinder 4 drives the No. 3 connecting rod 12 and the No. 2 connecting rod 11 to move downward, and the No. 2 connecting rod 11 drives the No. 1 slider 8 on both sides to move downward. The bottom end of the No. 1 slider 8 is hinged to the No. 1 connecting rod 10, and the bottom end of the No. 1 connecting rod 10 is hinged to the upper surface of the No. 2 slider 9. The No. 2 slider 9 is slidably connected to the upper surface of the base 1, so when the No. 1 slider 8 moves downward, it will drive the No. 2 slider 9 to slide along the direction of the slide groove. The height of the No. 2 slider 9 is less than the height of the die-cutting table 5, so when the template 6 moves downward for die-cutting, the movement of the No. 2 slider 9 will not affect the die-cutting work. When the die-cutting work is completed, the waste material falls to the surface of the base 1, and the cylinder 4 drives the template 6 to move upward. At this time, the No. 2 slider 9 will return to its original position, slide along the slide groove, and drive the waste material on the surface of the base 1 to achieve material stripping.

[0026] A feeding assembly is arranged in the groove and on the die-cutting table 5. The feeding assembly includes a rack 13 fixedly connected to the side wall of the second connecting rod 11 through a bracket. A gear 14 is rotatably connected to the upper surface of the die-cutting table 5 through the bracket. The rack 13 and the gear 14 are meshed with each other. Two rotating shafts 15 are rotatably connected to the side wall of the groove of the die-cutting table 5 through a bearing. A transmission wheel 16 is circumferentially fixedly connected to the two rotating shafts 15. A swing rod 17 is fixedly connected to the two rotating shafts 15. The two swing rods 17 are rotatably connected to a feeding plate 18. The gear 14 is fixedly connected to the transmission wheel 16 on the side away from the bracket. The three transmission wheels 16 are connected by belt transmission. The bearing between the gear 14 and the bracket adopts a one-way bearing. A pad is provided on the upper surface of the feeding plate 18. The pad is made of rubber. The number of tooth grooves on the rack 13 corresponds to the number of teeth on the gear 14.

[0027] When die-cutting is completed, the output end of the cylinder 4 moves upward, and drives the rack 13 to move upward through the bracket. The rack 13 and the gear 14 are meshed with each other. The bearing between the gear 14 and the bracket is a one-way bearing. When the rack 13 moves upward, it will drive the gear 14 to rotate. When the rack 13 moves downward, the gear 14 will not rotate. Therefore, when the rack 13 moves upward, the gear 14 rotates, thereby driving the transmission wheel 16 to rotate. The three rotating wheels 1 are connected by belt transmission, so the rotating shaft 15 and the two transmission wheels 16 in the groove will be driven to rotate, thereby driving the two swing rods 17 to rotate. The feeding plate 18 is rotatably connected to the two swing rods 17, so when the swing rod 17 rotates, the feeding plate 18 will perform a circular motion in a horizontal state, thereby realizing the delivery of the semi-finished product on the die-cutting table 5, and cooperating with the die-cutting work to be carried out synchronously, which is more efficient and convenient.

[0028] The detailed working process of the utility model is as follows:

[0029] When the air intake die-cutting is working, the processed material is placed on the die-cutting table 5, and the cylinder 4 is started to drive the template 6 to die-cut the material. At the same time, the output end of the cylinder 4 drives the No. 3 connecting rod 12 and the No. 2 connecting rod 11 to move downward, and the No. 2 connecting rod 11 drives the No. 1 slider 8 on both sides to move downward. The bottom end of the No. 1 slider 8 is hinged to the No. 1 connecting rod 10, and the bottom end of the No. 1 connecting rod 10 is hinged to the upper surface of the No. 2 slider 9. The No. 2 slider 9 is slidably connected to the upper surface of the base 1, so when the No. 1 slider 8 moves downward, it will drive the No. 2 slider 9 to slide along the direction of the slide groove. The height of the No. 2 slider 9 is less than the height of the die-cutting table 5, so when the template 6 moves downward for die-cutting, the movement of the No. 2 slider 9 will not affect the die-cutting work. When the die-cutting work is completed, the waste material falls to the surface of the base 1. At this time, the cylinder 4 drives the template 6 to move upward. At this time, the No. 2 slider 9 will return to its original position, slide along the slide groove, and drive the waste material on the surface of the base 1 to realize material stripping;

[0030] When die-cutting is completed, the output end of the cylinder 4 moves upward, and drives the rack 13 to move upward through the bracket. The rack 13 and the gear 14 are meshed with each other. The bearing between the gear 14 and the bracket is a one-way bearing. When the rack 13 moves upward, it will drive the gear 14 to rotate. When the rack 13 moves downward, the gear 14 will not rotate. Therefore, when the rack 13 moves upward, the gear 14 rotates, thereby driving the transmission wheel 16 to rotate. The three rotating wheels 1 are connected by belt transmission, so the rotating shaft 15 and the two transmission wheels 16 in the groove will be driven to rotate, thereby driving the two swing rods 17 to rotate. The feeding plate 18 is rotatably connected to the two swing rods 17, so when the swing rod 17 rotates, the feeding plate 18 will perform a circular motion in a horizontal state, thereby realizing the delivery of the semi-finished product on the die-cutting table 5, and cooperating with the die-cutting work to be carried out synchronously, which is more efficient and convenient.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
