[0024] The first motor 6 is fixedly installed on the right side of the chassis 1, and the synchronous shaft 7 is rotatably installed in the molding table 4, and the synchronous shaft 7 is fixedly connected to the discharging turntable 3 and the feeding turntable 5. The discharging turntable 3 and the feeding turntable 5 are driven to flip by the synchronous shaft 7 to adjust the vertical or horizontal state of the raw material sheet in the chassis 1, so that the state of the raw material sheet can be adjusted according to the needs of cutting, molding and cutting.

[0025] The driving traction roller group 8 and the limiting roller group 9 are respectively installed on the discharging turntable 3 and the feeding turntable 5. It is worth mentioning that the driving traction roller group 8 and the limiting roller group 9 are both composed of two roller units rotating in opposite directions. The traction roller group 8 pulls the raw material sheet so that the raw material sheet can be conveyed step by step in the chassis 1, and the limiting roller group 9 can flexibly clamp and limit the raw material sheet conveyed in a linear manner to avoid the deviation of the raw material sheet.

[0026] In the second part, a second motor 10 and a load frame 12 are fixedly installed at the front side of the chassis 1, and a punching table 11 corresponding to the load frame 12 and used to resist the raw material sheet is fixedly installed at the rear side of the chassis 1.

[0027] The wedge drive rod 15 is slidably mounted on the chassis 1; The strong spring 17 is fixedly installed on the load frame 12, and the wedge follower rod 18 is slidably mounted in the load frame 12. Under the elastic force of the strong spring 17, the wedge follower rod 18 actively squeezes the wedge driving rod 15.

[0028] The moving frame 19 is fixedly mounted on the wedge driving rod 15 .

[0029] The cutting end 20 is fixedly mounted on the movable frame 19, and a cutting groove 21 is opened in the punching table 11. The cutting end 20 continuously applies pressure to the raw material sheet during contact with the cutting groove 21. However, because the cutting end 20 is an incompletely sealed structure, the cut pieces are always connected to the raw material sheet.

[0030] The third part, a third motor 22 is fixedly installed at the rear side of the chassis 1, and a molding mechanism driven by the third motor 22 for punching and molding the raw material sheet is arranged on the chassis 1.

[0031] The lifting frame 24 is slidably mounted on the outer wall of the chassis 1 , and a vertical slot for slidingly fitting the lifting frame 24 is vertically opened on the outer wall of the chassis 1 to provide a guiding and limiting function for the vertically lifting lifting frame 24 .

[0032] The Y-shaped traction frame 26 is slidably mounted on the top of the chassis 1 , and the Y-shaped traction frame 26 is fixedly connected to the lifting frame 24 .

[0033] The extension bracket 27 is integrally connected to the chassis 1, and the boost angle plate 28 is axially mounted on the extension bracket 27. Figure 5 , Attachment Figure 6 With attached Fig. 9 The boost angle plate 28 is a right-angle plate structure. By applying pressure to the boost angle plate 28, the boost angle plate 28 is tilted and deflected toward the inclined groove 32, thereby squeezing the raw material sheet fragments corresponding to the inclined groove 32, so that the fragments are deflected with the raw material sheet as a fulcrum, forming a Fig.11 The right-angle bent plate structure.

[0034] The inclined groove 32 is inclinedly provided at the top of the shaping table 4.

[0035] Fourthly, a driving cylinder 33 is fixedly installed at the top of the chassis 1, and a cutting mechanism driven by the driving cylinder 33 for cutting the raw material sheet at the discharge port 202 is provided on the chassis 1. The cutting mechanism consists of a driving wedge 34, a return spring 35 fixedly connected thereto, and a driven wedge 36 movably abutted against the driving wedge 34, and a cutting end 37: Specifically refer to the attached Figure 5 to the attached Fig.10 The driving wedge 34 is fixedly connected to the output end of the driving cylinder 33, and the driving wedge 34 is slidably installed at the top of the chassis 1.

[0036] The return spring 35 is fixedly installed in the chassis 1. The driven wedge 36 is slidably installed on the right side wall of the chassis 1 where the discharge port 202 is opened. A vertical groove for vertically installing the return spring 35 and the driven wedge 36 is opened in the right side wall of the chassis 1. When the driven wedge 36 is squeezed by the driving wedge 34, it drives the cutting end 37 to move vertically downward to cut the raw material sheet.

[0037] The cutting end 37 is fixedly installed on the driven wedge 36.

[0038] Specifically refer to the attached Figure 7 , a first connecting rod 16 is pin-connected between the moving nut 14 and the wedge head driving rod 15. Under the limiting action of the first connecting rod 16, the moving nut 14 moves linearly back and forth along with the ball screw 13. The cutting end 20 and the cutting groove 21 are in a matching C-shaped structure, so that when the cutting end 20 contacts the cutting groove 21, the raw material sheet is incompletely cut to ensure that the broken material is always connected to the raw material sheet.

[0039] A second connecting rod 25 with an eccentric setting is pin-connected to the traction turntable 23, and the second connecting rod 25 is pin-connected to the lifting frame 24.

[0040] A support spring 29 is fixedly installed in the pressure increasing angle plate 28, and a slider 30 slidably sleeved on the pressure increasing angle plate 28 is welded on the support spring 29. A third connecting rod 31 is pin-connected between the slider 30 and the Y-shaped traction frame 26.

[0041] It should be noted that the specific model specifications of the first motor 6, the second motor 10, the third motor 22 and the driving cylinder 33 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated here.

[0042] The functional principle of the present invention can be described through the following operation modes: First, place the raw material sheet to be processed at the positions of the traction roller group 8 and the limit roller group 9. Use the traction roller group 8 to traction the raw material sheet to move vertically into the chassis 1 until the raw material sheet contacts the stamping table 11. It should be noted that the traction roller group 8 is equipped with a driving motor, and the two roller monomers are provided with meshing transmission gears. Under the active traction of the traction roller group 8, the raw material sheet moves linearly; Secondly, control the second motor 10 to start. The output end of the second motor 10 drives the ball screw 13 to rotate. The moving nut 14 drives the two wedge head driving rods 15 to move in the opposite direction through the first connecting rod 16 to act on the wedge head driven rod 18 and the strong spring 17. The wedge head driven rod 18 drives the cutting end 20 to move through the moving frame 19. The cutting end 20 presses the raw material sheet corresponding to the cutting groove 21. After cutting, the cutting end 20 resets, so that two uncompletely cut scraps are formed on the raw material sheet; Thirdly, control the first motor 6 to start. The output end of the first motor 6 drives the discharge turntable 3 and the feed turntable 5 to rotate 90° through the synchronous rotating shaft 7, so that the cut raw material sheet is horizontally placed on the shaping table 4. The vertically placed raw material sheet is convenient to fit on the stamping table 11, while the horizontally placed raw material sheet is convenient to fit on the shaping table 4; Then, control the third motor 22 to start. The output end of the third motor 22 drives the traction turntable 23 to rotate. The traction turntable 23 traction the lifting frame 24 to lift vertically through the second connecting rod 25. The lifting frame 24 synchronously lifts inside the top of the chassis 1 through the Y-shaped traction frame 26. The Y-shaped traction frame 26 presses the support spring 29 and the slider 30, so that the pressurizing angle plate 28 deflects with the extension bracket 27 as the fulcrum, and squeezes the scraps cut from the raw material sheet into the inclined groove 32. After forming, the pressurizing angle plate 28 resets. Under the dual action of the pressurizing angle plate 28 and the shaping table 4, the scraps on the raw material sheet are completely deformed; Finally, the traction roller group 8 and the limit roller group 9 drive the cut and shaped raw material sheet to move towards the discharge port 202. Control the driving cylinder 33 to start. The driving cylinder 33 drives the driving wedge block 34 to move to press the driven wedge block 36 and the return spring 35, so that the driven wedge block 36 drives the cutting end 37 to move vertically downward to cut the raw material sheet. After cutting, a lid lifter is formed. Control the first motor 6 to start to reset the raw material sheet to the vertical state.

[0043] It should be noted that: On the one hand, the cutting end 20 performs a U-shaped cutting on the raw material sheet to facilitate the formation of scraps that are still connected to the raw material sheet but can be independently bent; On the other hand, the pressurizing angle plate 28 presses the cut scraps in the inclined groove 32 to facilitate bending and shaping the scraps in the inclined groove 32.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

9. A method for processing a capping device according to claim 8, characterized in that: The method includes the following steps: Step S1, place the raw material sheet to be processed at the positions of the traction roller group (8) and the limit roller group (9), use the traction roller group (8) to traction the raw material sheet to move vertically into the chassis (1) until the raw material sheet contacts the stamping table (11); Step S2, control the second motor (10) to start. The output end of the second motor (10) drives the ball screw (13) to rotate. The moving nut (14) drives two wedge driving rods (15) to move in the opposite direction through the first connecting rod (16), so as to act on the wedge driven rod (18) and the strong spring (17). The wedge driven rod (18) drives the cutting end (20) to move through the moving frame (19). The cutting end (20) presses the raw material sheet corresponding to the cutting groove (21) for cutting, and then the cutting end (20) resets after cutting; Step S3, control the first motor (6) to start. The output end of the first motor (6) drives the discharging turntable (3) and the feeding turntable (5) to rotate 90° through the synchronous rotating shaft (7), so that the cut raw material sheet is horizontally placed on the shaping table (4); Step S4, control the third motor (22) to start. The output end of the third motor (22) drives the traction turntable (23) to rotate. The traction turntable (23) pulls the lifting frame (24) to move vertically through the second connecting rod (25). The lifting frame (24) synchronously moves up and down inside the top end of the chassis (1) through the Y-shaped traction frame (26). The Y-shaped traction frame (26) squeezes the support spring (29) and the slider (30) through the third connecting rod (31), so that the pressurizing angle plate (28) deflects with the extension bracket (27) as the fulcrum, and squeezes the scraps cut from the raw material sheet into the inclined groove (32). After forming, the pressurizing angle plate (28) resets; Step S5, the traction roller group (8) and the limiting roller group (9) drive the raw material sheet after cutting and shaping to move towards the discharging port (202). Control the driving cylinder (33) to start. The driving cylinder (33) drives the driving wedge block (34) to move to squeeze the driven wedge block (36) and the return spring (35), so that the driven wedge block (36) drives the cutting end (37) to move vertically downward to cut the raw material sheet. After cutting, a lid lifter is formed. Control the first motor (6) to start to reset the raw material sheet to the vertical state.

10. A method for processing a lid opener according to claim 9, characterized in that: In the step S2, the cutting end (20) performs a U-shaped cutting on the raw material sheet. In the step S4, the pressurizing angle plate (28) squeezes the scraps formed by cutting in the inclined groove (32).
