Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically to an automatic waste removal device for cardboard box die-cutting machines. Background Technology

[0002] In the carton production process, the die-cutting process is a key step that determines the forming accuracy and appearance quality of the carton. Its core is to cut the cardboard into a specific structure according to the preset shape using a die-cutting machine. Commonly used die-cutting equipment includes flatbed die-cutting machines, rotary die-cutting machines, and rotary die-cutting machines. Among them, the flatbed die-cutting machine uses a waste removal needle and a waste removal plate in combination. By inserting the waste removal needle into the waste removal hole, the waste material is pushed out or hooked out, thereby removing the waste material after the carton is die-cut. The spacing of the waste removal needles is mostly fixed, which cannot be flexibly adjusted according to the size and distribution of the waste removal holes of different sizes of carton die-cutting plates, reducing the adaptability of the waste removal needles. Secondly, the waste removal mechanism of the removal device and the die-cutting machine frame use traditional connection methods such as bolts, which makes the disassembly and installation process cumbersome and reduces the efficiency of disassembly and installation of the waste removal mechanism. Utility Model Content

[0003] To address the issues of the inability to flexibly adjust the size and distribution of waste removal holes according to different specifications of carton die-cutting plates, and the problem of fixing the fixing frame to the waste removal mechanism with bolts, the purpose of this utility model is to provide an automatic waste removal device for carton die-cutting machines.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: an automatic waste removal device for a carton die-cutting machine, comprising a waste removal mechanism, wherein the waste removal mechanism includes a fixed frame on a waste removal plate and several sets of upper waste removal needles, each set consisting of two upper waste removal needles; the top of the waste removal plate has several waste removal holes; and an adjustment mechanism is provided at the top of every two upper waste removal needles, the adjustment mechanism being used to adjust the spacing between every two upper waste removal needles; the adjustment mechanism includes a U-shaped support frame, inside which two horizontal frames are fixedly installed, the two horizontal frames being located at the top and bottom respectively; a screw is rotatably installed in the middle of the horizontal frame, and a moving block is threadedly connected to the outer side of the screw.

Detailed Implementation

[0019] 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.

[0020] Example: Figure 1-9As shown, this utility model provides an automatic waste removal device for a carton die-cutting machine, including a waste removal mechanism 1. The waste removal mechanism 1 includes a fixed frame 12 on a waste removal plate 11 and several sets of upper waste removal needles 13. Each set of upper waste removal needles 13 consists of two needles. The top of the waste removal plate 11 is provided with several waste removal holes. The top of every two upper waste removal needles 13 is provided with an adjustment mechanism 2. The adjustment mechanism 2 is used to adjust the spacing between every two upper waste removal needles 13. The adjustment mechanism 2 includes a U-shaped support frame 20. Two crossbeams 21 are fixedly installed inside the support frame 20. The two crossbeams 21 are located at the top and bottom respectively. A screw 22 is rotatably installed in the middle of the crossbeam 21. A moving block 23 is threadedly connected to the outside of the screw 22. A connecting rod 24 is rotatably installed on both sides of the moving block 23. A slider 25 is rotatably installed at the end of the connecting rod 24 away from the moving block 23. The slider 25 is slidably connected to the lower crossbeam 21. A needle seat 26 is fixedly installed at the bottom of the slider 25. A through groove is opened at the bottom of the needle seat 26 to cooperate with the upper cleaning waste needle 13. The needle seat 26 and the upper cleaning waste needle 13 are connected by bolts. A locking mechanism 3 is fixedly installed at the top of the screw 22, and the locking mechanism 3 is used to fix the screw 22. A quick-release mechanism 4 is fixedly installed at the top of the support frame 20. The quick-release mechanism 4 is used to install the support frame 20 on the upper fixed frame 12. By setting the adjustment mechanism 2, the rotation of the screw 22 drives the moving block 23 to move. During the movement of the moving block 23, the connecting rod 24 pushes the slider 25 to slide along the lower cross frame 21 to both sides or to the middle. The slider 25 drives the upper cleaning needle 13 of the needle seat 26 to move to both sides or to the middle. Thus, the distance between the two upper cleaning needles 13 can be adjusted according to the size of the cleaning hole on the cleaning plate 11, which improves the adaptability of the cleaning needle. In actual use, a lower fixed frame and a lower cleaning needle are also provided below the cleaning plate 11. This lower fixed frame and lower cleaning needle correspond to the upper fixed frame 12 and the upper cleaning needle 13 and have the same structure. The upper fixed frame 12, the lower fixed frame, and the cleaning plate 11 are all installed on the carton die-cutting machine.

[0021] The quick-release mechanism 4 includes a support rod 40, which is fixedly connected to the support frame 20. A support block 41 is fixedly installed at the top of the support rod 40. Springs 42 are fixedly installed on both sides of the support block 41. A push block 43 is fixedly installed on the side of the springs 42 away from the support block 41. An insert rod 44 is fixedly installed on the side of the push block 43 away from the springs 42. Several fixing rods 45 are fixedly installed at the bottom of the upper fixing frame 12. The fixing rods 45 are perpendicular to the waste cleaning holes. The bottom ends of the fixing rods 45 are... A through slot 2 is provided, and a slot 46 for use with the insertion rod 44 is provided through the bottom of the fixing rod 45; by setting a quick release mechanism 4, the insertion rod 44 and the spring 2 42 cooperate to allow the insertion rod 44 to be inserted into or disengaged from the slot 46 of the fixing rod 45, thereby realizing the quick installation and disassembly between the support frame 20 and the upper fixing frame 12, so that the waste removal mechanism 1 can be used on other upper fixing frames 12 (the upper fixing frame 12 and the waste removal plate 11 are replaced with the corresponding ones at the same time).

[0022] The locking mechanism 3 includes a gear 30, which is fixedly connected to a screw 22. Four evenly distributed annular fixing blocks 31 are provided on the outside of the gear 30. The fixing blocks 31 are fixedly connected to the lower inner surface of the support frame 20. A spring 32 is fixedly installed on the side of the fixing block 31 closest to the gear 30, and a locking block 33 that cooperates with the gear 30 is fixedly installed on the side of the spring 32 away from the fixing block 31. By setting up the locking mechanism 3, the rotation of the screw 22 drives the gear 30 to rotate. The gear 30 cooperates with the locking block 33, and under the elastic force of the spring 32, the locking block 33 always fits against the tooth groove of the gear 30, thus achieving rotation when the screw 22 is rotated and self-locking when the screw 22 is not rotated.

[0023] The second spring 42 has a telescopic rod 47 inside. One end of the telescopic rod 47 is fixedly connected to the push block 43, and the other end of the telescopic rod 47 is fixedly connected to the support block 41. By setting the telescopic rod 47, the second spring 42 is more stable when it retracts.

[0024] Each spring 32 has a stabilizing rod 34 inside. One end of the stabilizing rod 34 is fixedly connected to the locking block 33, and the stabilizing rod 34 is slidably connected to the fixing block 31. By setting the stabilizing rod 34, the spring 32 is more stable when it contracts, and at the same time, the stability of the locking block 33 when it moves is also increased.

[0025] A rotating wheel 27 is fixedly installed on the outer wall of the screw 22. Several trapezoidal anti-slip strips are fixedly installed on the outside of the rotating wheel 27. By setting the rotating wheel 27, it is easy to rotate the screw 22. At the same time, the design of the protective strips increases the friction between the hand and the rotating wheel 27, making it easier for the operator to rotate the rotating wheel 27 and drive the screw 22 to rotate.

[0026] Both sides of the support rod 40 are provided with slots 48 that cooperate with the push block 43; by providing slots 48, the push block 43 can move without being affected by the support rod 40.

[0027] An operating button is fixedly installed on the side of the push block 43 near the insertion rod 44; by setting the operating rod, it is easier to squeeze the push block 43 at the same time, drive the push block 43 to move, and move the insertion rod 44 away from the slot 46 on the fixed rod 45.

[0028] Working principle: In actual use, waste removal: When the die-cut cardboard is conveyed to the waste removal plate 11, the upper waste removal needle 13 is inserted downward into the waste removal hole, and the lower waste removal needle is pushed upward. The two work together to push or hook out the waste of the carton from the waste removal hole, thus completing the separation of waste from the finished cardboard and realizing the removal of waste from the carton. When it is necessary to adjust the distance between the two upper cleaning waste needles 13: the operator rotates the rotating wheel 27 to drive the screw 22 to rotate along the middle of the cross frame 21. The rotation of the screw 22 drives the moving block 23 to move. Then the connecting rod 24 pulls the slider 25 to slide along the lower cross frame 21, and drives the needle seat 26 and the upper cleaning waste needle 13 to move towards the middle. Alternatively, the connecting rod 24 pushes the slider 25 to slide along the lower cross frame 21, and drives the needle seat 26 and the upper cleaning waste needle 13 to move to both sides, thereby realizing the adjustment between the two upper cleaning waste needles 13. While the screw 22 is rotating, the gear 30 rotates synchronously. During the rotation of the gear 30, the teeth of the gear 30 press against the locking block 33, causing the locking block 33 to move away from the tooth groove of the gear 30. At the same time, the compression spring 32 contracts, and the stabilizing rod 34 slides along the fixed block 31 with the locking block 33. As the gear 30 continues to rotate, the locking block 33 continuously engages with different tooth grooves of the gear 30 under the action of the spring force. When the operator stops rotating the wheel 27, the screw 22 and the gear 30 stop rotating. Under the action of the spring 32, the locking block 33 is embedded in the current tooth groove of the gear 30, forming a mechanical self-locking mechanism, which prevents the screw 22 from rotating on its own. When it is necessary to assemble the support frame 20 with the upper fixed frame 12, firstly, the operator holds the support rod 40 and simultaneously squeezes the operating buttons on both sides of the support rod 40. When the operating buttons are squeezed, the push block 43 moves towards the middle, the spring 42 and the telescopic rod 47 retract, and the insertion rod 44 moves away from the slot 46 on the fixed rod 45. Then, the support rod 40 is inserted into the through groove 2 at the bottom of the fixed rod 45. When the support rod 40 can no longer be inserted into the fixed rod 45, the operator releases his hand. Under the rebound action of the spring 42, the corresponding push block 43 rebounds, and the insertion rod 44 is inserted into the slot 46, thereby fixing the support frame 20 and the components on the support frame 20 to the upper fixed frame 12. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
