High-efficiency reciprocating die-cutting mechanism for die-cutting machine

Abstract

This utility model discloses a high-efficiency reciprocating die-cutting mechanism for a die-cutting machine, relating to the field of die-cutting machine technology. It includes a die-cutting table, a support frame fixedly connected to one side of the top of the die-cutting table, a sliding column inside the support frame, a driving structure at the top of the sliding column, a hollow seat fixedly connected to the outside of the sliding column, and an installation groove at the bottom of the sliding column. Square slots are formed on both sides of the installation groove. By rotating a throttle, a worm gear engages with a worm wheel, which drives a bidirectional screw to rotate inside the hollow seat. The bidirectional screw is threadedly connected to two sliding blocks, causing the two sliding blocks to move in opposite directions. The sliding blocks drive a Z-shaped rod and an L-shaped insert rod to move synchronously. The Z-shaped rod moves a limiting block away from the limiting slot, while the L-shaped insert rod moves out of the fixed slot, thereby releasing the blade from its fixation and facilitating blade disassembly and replacement.

Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a high-efficiency reciprocating die-cutting mechanism for a die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. Die-cutting machines use steel knives, hardware molds, or steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut printed materials or cardboard into a certain shape. They are important equipment for printing and packaging processing.

[0003] In the prior art, the high-efficiency die-cutting paper processing die-cutting machine with authorization announcement number CN217573119U has a reciprocating mechanism installed on the support frame, and two symmetrically distributed clamping mechanisms installed on the mounting frame. The clamping mechanism includes a threaded rod, a fixed block, an adjusting block, a limit ring, an electric push rod, and a pressure plate. The fixed block is movably sleeved on the outside of the threaded rod, and the adjusting block is threaded on the outside of the threaded rod. The bottom of the adjusting block is fixedly connected to the limit ring, and the bottom of the limit ring is fixedly connected to the electric push rod. The pressure plate is fixedly connected to the telescopic end of the electric push rod.

[0004] While the above solution offers many advantages, it also has the following drawbacks: when the blades need to be replaced after prolonged use, they cannot be disassembled, which increases the difficulty of blade replacement. In addition, adjusting the positions of the two pressure plates is not convenient enough, reducing the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency reciprocating die-cutting mechanism for a die-cutting machine, so as to solve the problem in the prior art that when the blade needs to be replaced after a long period of use, it cannot be disassembled, thus increasing the difficulty of blade replacement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency reciprocating die-cutting mechanism for a die-cutting machine, comprising a die-cutting table, a support frame fixedly connected to one side of the top of the die-cutting table, a sliding column provided inside the support frame, a driving structure provided at the top of the sliding column, a hollow seat fixedly connected to the outside of the sliding column, an installation groove provided at the bottom of the sliding column, square slots formed on both sides of the installation groove, an installation block provided inside the installation groove, a fixing groove provided on both sides of the installation block, a blade fixedly connected to the bottom of the installation block, a bidirectional screw rotatably connected inside the hollow seat, a worm gear fixedly connected to the outside of the bidirectional screw, a worm gear meshing with the outside of the worm gear, sliding blocks threadedly connected to both ends of the outside of the bidirectional screw, L-shaped inserts fixedly connected to the bottom of each of the two sliding blocks, one end of each of the two L-shaped inserts passing through the two square slots and extending into the two fixing grooves, a limiting structure provided between the two sliding blocks and the blade, and a clamping structure provided on the other side of the top of the die-cutting table.

[0007] Preferably, the driving structure includes a mounting base, which is fixedly connected to the top of the sliding column. A roller is installed inside the mounting base, and a cam is provided on the top of the roller. A motor is provided on one side of the cam, and the motor is fixedly connected to the top of the support frame. The output end of the motor is fixedly connected to the cam. The cam is driven to rotate by the motor, and the rotation of the cam reciprocates and compresses the roller, thereby pushing the sliding column to slide on the fixed plate, realizing the function of efficient reciprocating die-cutting.

[0008] Preferably, the driving structure further includes a spring, which is sleeved on the outside of the sliding column. The top end of the spring is fixedly connected to the mounting base, and the bottom end of the spring is fixedly connected to a fixing plate. The fixing plate is slidably connected to the outside of the sliding column, and both ends of the fixing plate are fixedly connected to the support frame. The spring plays a role in buffering and resetting during the driving process.

[0009] Preferably, both ends of the worm gear pass through the inner side of the hollow seat and are rotatably connected to the hollow seat. A throttle handle is installed at one end of the worm gear. A long groove is opened at the bottom of the hollow seat, and both L-shaped inserts pass through the two long grooves.

[0010] Preferably, the limiting structure includes two limiting grooves, which are respectively opened on both sides inside the support frame. A square slide cylinder is slidably arranged inside each of the two limiting grooves. A connecting block is fixedly connected to both the front and rear sides of the square slide cylinder. Both connecting blocks are fixedly connected to the hollow seat. A limiting block is slidably connected inside each of the two square slide cylinders. A sliding groove is opened at the top of the square slide cylinder. A Z-shaped rod is fixedly connected to the top of the limiting block. The Z-shaped rod is arranged inside the sliding groove. The top end of the Z-shaped rod passes through the long groove and is fixedly connected to the sliding block.

[0011] Preferably, the limiting structure further includes two limiting slots, which are respectively opened at both ends of the blade, and two limiting blocks are respectively disposed inside the two limiting slots. The setting of the limiting slots further enhances the limiting effect on the blade. When the limiting blocks cooperate with the limiting slots, the blade can be fixed more stably, preventing the blade from shaking or shifting during the die-cutting process and ensuring the die-cutting quality.

[0012] Preferably, the clamping structure includes a mounting frame, which is fixedly connected to the other side of the top of the support frame. A convex groove is provided at the top of the inside of the mounting frame. A double-acting screw is rotatably connected inside the convex groove. A worm gear is fixedly connected to the outside of the double-acting screw. A worm is meshed with the outside of the worm gear. Both ends of the worm pass through the inside of the convex groove and are rotatably connected to the mounting frame. A throttle handle is installed at one end of the worm. Both ends of the double-acting screw are threaded with convex blocks.

[0013] Preferably, the clamping structure further includes two sliding frames, both of which are slidably connected to the outside of the mounting bracket. The two sliding frames are respectively fixedly connected to two convex blocks. A hydraulic cylinder is fixedly connected to the bottom of each sliding frame. A pressure plate is fixedly connected to the telescopic end of the hydraulic cylinder. Two limiting posts are fixedly connected to the top of the pressure plate. The tops of the two limiting posts penetrate the sliding frame and are slidably connected to it.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application involves rotating a throttle, which engages a worm gear and a worm wheel. The worm wheel drives a double-acting screw to rotate inside the hollow seat. The double-acting screw is threadedly connected to two sliding blocks. The two sliding blocks move in opposite directions, causing the Z-shaped rod and the L-shaped insert to move synchronously. The Z-shaped rod then moves the limiting block away from the limiting slot, while the L-shaped insert moves out of the fixing slot, thereby releasing the blade from its fixation and facilitating disassembly and replacement.

[0016] 2. This application uses the output end of the motor to drive the cam to rotate. The rotation of the cam reciprocates and compresses the roller, thereby pushing the sliding column to slide on the fixed plate. The spring plays a role in buffering and resetting in this process, ensuring that the sliding column can reciprocate smoothly, thereby driving the blade to perform die-cutting operation and realizing the function of efficient reciprocating die-cutting.

[0017] 3. This application utilizes the rotation of the second throttle, which engages the second worm gear with the second worm wheel. The second worm wheel drives the second bidirectional screw to rotate on the mounting frame. The rotation of the second bidirectional screw causes the two convex blocks to move closer or further apart, thereby causing the two sliding frames to slide on the outside of the mounting frame. This allows for adjustment of the pressure plate position so that the two pressure plates can accommodate papers of different widths. Activating the hydraulic cylinder allows for the extension and retraction of the hydraulic cylinder to control the up and down movement of the pressure plate, thereby achieving the pressing or releasing of the die-cutting material.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for a high-efficiency reciprocating die-cutting mechanism for a die-cutting machine, including a die-cutting table 1, a support frame 2 fixedly connected to one side of the top of the die-cutting table 1, a sliding column 3 provided inside the support frame 2, a driving structure provided at the top of the sliding column 3, a hollow seat 9 fixedly connected to the outside of the sliding column 3, an installation groove 14 opened at the bottom of the sliding column 3, square slots formed on both sides of the installation groove 14, an installation block 11 provided inside the installation groove 14, a fixing groove 12 opened on both sides of the installation block 11, a blade 10 fixedly connected to the bottom of the installation block 11, a bidirectional screw 15 rotatably connected inside the hollow seat 9, and a worm gear fixedly connected to the outside of the bidirectional screw 15. The outer side of the worm gear 21 is meshed with a worm 22. Both ends of the worm 22 pass through the inner side of the hollow seat 9 and are rotatably connected to the hollow seat 9. A throttle is installed at one end of the worm 22. Both ends of the double screw 15 are threaded with sliding blocks 16. The bottom of each sliding block 16 is fixedly connected with an L-shaped insert 20. The bottom of the hollow seat 9 has a long groove 900. The two L-shaped inserts 20 pass through the two long grooves 900. One end of each L-shaped insert 20 passes through two square slots and extends into the two fixed slots 12. A limiting structure is provided between the two sliding blocks 16 and the blade 10. A clamping structure is provided on the other side of the top of the die-cutting table 1.

[0028] The limiting structure includes two limiting grooves 200, which are respectively opened on both sides inside the support frame 2. A square slide cylinder 18 is slidably arranged inside each of the two limiting grooves 200. A connecting block 19 is fixedly connected to both the front and rear sides of the square slide cylinder 18. Both connecting blocks 19 are fixedly connected to the hollow seat 9. A limiting block 170 is slidably connected inside each of the two square slide cylinders 18. A slide groove 180 is opened at the top of the square slide cylinder 18. A Z-shaped rod 17 is fixedly connected to the top of the limiting block 170. The Z-shaped rod 17 is arranged inside the slide groove 180. The top end of the Z-shaped rod 17 passes through the long groove 900 and is fixedly connected to the slide block 16. The limiting structure also includes two limiting slots 13, which are respectively opened at both ends of the blade 10. The two limiting blocks 170 are respectively arranged inside the two limiting slots 13.

[0029] Specifically, when the throttle is turned, the worm gear 22 meshes with the worm wheel 21. The worm wheel 21 drives the double-acting screw 15 to rotate inside the hollow seat 9. The double-acting screw 15 is threadedly connected to two sliding blocks 16. The two sliding blocks 16 move in opposite directions. The sliding blocks 16 drive the Z-shaped rod 17 and the L-shaped insert rod 20 to move synchronously. The Z-shaped rod 17 drives the limiting block 170 away from the limiting slot 13, while the L-shaped insert rod 20 moves out of the fixing slot 12, thereby releasing the blade 10 from fixation and making it easier for personnel to disassemble and replace the blade 10.

[0030] Example: Figure 1 As shown, the drive structure includes a mounting base 6, which is fixedly connected to the top of the sliding column 3. A roller 7 is installed inside the mounting base 6, and a cam 8 is provided on the top of the roller 7. A motor is provided on one side of the cam 8, and the motor is fixedly connected to the top of the support frame 2. The output end of the motor is fixedly connected to the cam 8. The drive structure also includes a spring 5, which is sleeved on the outside of the sliding column 3. The top of the spring 5 is fixedly connected to the mounting base 6, and a fixing plate 4 is fixedly connected to the bottom of the spring 5. The fixing plate 4 is slidably connected to the outside of the sliding column 3, and both ends of the fixing plate 4 are fixedly connected to the support frame 2.

[0031] Specifically, the motor is started. The specific motor model is not limited, but is compatible with the equipment. The output end of the motor drives the cam 8 to rotate. The rotation of the cam 8 presses the roller 7 back and forth, thereby pushing the sliding column 3 to slide on the fixed plate 4. The spring 5 plays a role in buffering and resetting in this process, ensuring that the sliding column 3 can move back and forth smoothly, thereby driving the blade 10 to perform die-cutting operations and realizing the function of efficient reciprocating die-cutting.

[0032] Example: Figure 1 , Figure 6 and Figure 7 As shown, the clamping structure includes a mounting frame 23, which is fixedly connected to the other side of the top of the support frame 2. A convex groove 24 is provided at the top of the mounting frame 23. A double-acting screw 25 is rotatably connected inside the convex groove 24. A worm gear 26 is fixedly connected to the outside of the double-acting screw 25. A worm 27 is meshed with the outside of the worm gear 26. Both ends of the worm 27 pass through the inside of the convex groove 24 and are rotatably connected to the mounting frame 23. A throttle handle 2 is installed at one end of the worm 27. Both ends of the double-acting screw 25 are threadedly connected to convex blocks 28. The clamping structure also includes two sliding frames 29, which are slidably connected to the outside of the mounting frame 23. The two sliding frames 29 are fixedly connected to the two convex blocks 28 respectively. A hydraulic cylinder 30 is fixedly connected to the bottom of the sliding frame 29. A pressure plate 31 is fixedly connected to the telescopic end of the hydraulic cylinder 30. Two limiting posts 32 are fixedly connected to the top of the pressure plate 31. The tops of the two limiting posts 32 pass through the sliding frame 29 and are slidably connected to the sliding frame 29.

[0033] Specifically, rotating the second throttle engages the second worm gear 27 with the second worm wheel 26. The second worm wheel 26 drives the second bidirectional screw 25 to rotate on the mounting frame 23. The rotation of the second bidirectional screw 25 causes the two convex blocks 28 to move closer or further apart, thereby causing the two sliding frames 29 to slide on the outside of the mounting frame 23, thus adjusting the position of the pressure plate 31 so that the two pressure plates 31 can accommodate papers of different widths. Activating the hydraulic cylinder 30 allows the extension and retraction of the hydraulic cylinder 30 to control the up and down movement of the pressure plate 31, thereby pressing or releasing the die-cutting material.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
