Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, and in particular to an automatic dust removal blade holder for a circular die-cutting machine. Background Technology

[0002] Circular die-cutting machines are processing equipment used in the electronics, packaging, and leather industries. They cut various flexible materials through the high-speed rotation of the die roller, achieving high-precision and high-efficiency die-cutting operations. They occupy an important position in modern industrial production. During the die-cutting process, the material cutting generates a large amount of debris and dust. If not cleaned in time, it will not only affect the service life of the die roller, but also reduce the processing accuracy and quality of the product. Therefore, dust removal has become a key aspect of the operation of circular die-cutting machines.

[0003] Traditional dust removal methods for rotary die-cutting machines rely on manual periodic cleaning. Manual cleaning is not only inefficient and poses certain safety hazards, but it is also difficult to achieve real-time cleaning. To address the shortcomings of traditional dust removal methods, existing technologies have improved the dust removal device of rotary die-cutting machines by using a dust-adhesive cartridge. However, in actual use, when the stickiness of the dust-adhesive component decreases, the dust removal effect is greatly reduced, and it is impossible to replace it in time to maintain efficient dust removal, resulting in reduced production efficiency and affecting product quality stability. Therefore, an automatic dust removal blade holder for rotary die-cutting machines is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic dust removal blade holder for a circular die-cutting machine, aiming to improve the problem of the difficulty in quickly replacing the dust collection tube in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic dust removal blade holder for a rotary die-cutting machine, comprising a support, wherein a dust-adhesive mechanism is provided inside the support, an mounting plate is fixedly connected to the left side of the support, a cutting mechanism is provided on the top of the mounting plate, and a side plate is fixedly connected to the right side of the support, wherein a dust-collecting mechanism is provided on the top of the side plate. The dust-adhesive mechanism includes two through rings, the outer walls of which are rotatably connected to the inner wall of the bracket. A retaining ring is fixedly connected to the outer wall of the left through ring, and a retaining ring is fixedly connected to the outer walls of both through rings. A rotating assembly is provided between the adjacent two through rings, and the same sticking roller is rotatably connected to the adjacent side of the outer walls of the two through rings. A pressing assembly is provided on the right side of the outer wall of the bracket.

A vacuum hood is connected to the left side of the suction tube. A fan is fixedly connected to the inner wall of the suction tube. A dust collection box is fixedly connected to the top of the side plate. A turbulence-inducing component is provided inside the suction tube. The bottom of the suction tube is connected to the top of the dust collection box.

[0007] As a further description of the above technical solution: The cutting mechanism includes a servo motor, the bottom of which is fixedly connected to the top of the mounting plate. The output end of the servo motor is fixedly connected to a drive shaft, and a cutter roller is fixedly connected to the outer wall of the drive shaft. A transmission assembly is provided on the outside of the drive shaft.

[0008] As a further description of the above technical solution: The rotating assembly includes a rotating rod, the outer wall of which is slidably connected to the inner walls of two through rings, and multiple locking blocks are fixedly connected to the outer wall of the rotating rod. The outer wall of the sticky roller is provided with a locking groove.

[0009] As a further description of the above technical solution: The clamping assembly includes an isolation disc, the inner wall of which is rotatably connected to the outer wall of a rotating rod.

[0012] As a further description of the above technical solution: The inner wall of the second gear is fixedly connected to the outer wall of the left through ring.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when the cutting mechanism rotates, it can directly drive the left-side through-ring to rotate, and through the linkage of the rotating rod, the locking block and the locking groove, the power is transmitted to the sticking roller. The sticking roller can be operated without an additional power source, which simplifies the structure and reduces energy consumption. Through the sequential dust removal design of the dust collection mechanism and the sticking roller, the dust removal of the cutting roller is graded, which improves the dust removal effect. At the same time, when the sticking roller's stickiness decreases or too much dust affects the dust removal effect, the rotating rod can be pulled out from the inner wall of the through-ring to quickly replace the sticking roller.

[0014] 2. In this utility model, a negative pressure airflow is formed inside the suction pipe by the fan, which enables the dust suction hood to suck up the dust on the surface and surrounding area of ​​the sticky roller under the action of negative pressure, thus achieving the initial collection of dust. The conical cylinder in the turbulence component increases the airflow speed and improves the dust conveying efficiency. At the same time, the dustproof plate can prevent dust from directly entering the fan and causing wear on the blades, thus extending its service life. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] See attached document Figure 1 Appendix Figure 2 and attached Figure 3This utility model provides an embodiment of an automatic dust removal blade holder for a circular die-cutting machine, including a support 1, which serves as the supporting foundation for the overall structure and provides an installation carrier and stable support for other components. The support 1 is equipped with a dust-adhesive mechanism 2 for adhering fine dust on the blade roller 403. A mounting plate 3 is fixedly connected to the left side of the support 1 to provide an installation surface for the cutting mechanism 4. The cutting mechanism 4 is installed on the top of the mounting plate 3 for completing the die-cutting operation of the material. A side plate 5 is fixedly connected to the right side of the support 1 to provide installation support for the dust-collecting mechanism 6. The dust-collecting mechanism 6 is installed on the top of the side plate 5 for collecting larger dust from the surface of the adhesive roller 205, reducing the workload of the dust-adhesive mechanism 2 and improving the overall dust removal efficiency. The dust-adhesive mechanism 2 includes two through-rings 201. The outer walls of both through-rings 201 are rotatably connected to the inner wall of the bracket 1. The through-rings 201 provide support and a base for the rotation of the adhesive roller 205, ensuring that the adhesive roller 205 can rotate flexibly. A retaining ring 202 is fixedly connected to the outer wall of the left through-ring 201. The retaining ring 202 serves as a limit to prevent axial displacement of the adhesive roller 205 during rotation. A retaining ring 203 is fixedly connected to the outer walls of both through-rings 201. The retaining ring 203 is used to limit the position of the through-rings 201 and ensure stable rotation of the through-rings 201. A rotating assembly 204 is provided between the adjacent through-rings 201. The rotating assembly 204 realizes the power transmission between the through-rings 201 and the adhesive roller 205, so that the rotation of the through-rings 201 can drive the adhesive roller 205 to rotate synchronously. The rotating assembly 204 includes a rotating rod 2041. The outer wall of the rotating rod 2041 is slidably connected to the inner wall of the two through-rings 201. The rotating rod 2041 serves as a connection between the two through-rings 201. The components 01 and the adhesive roller 205 ensure the stability and reliability of power transmission. Multiple locking blocks 2042 are fixedly connected to the outer wall of the rotating rod 2041. These locking blocks 2042 engage with the locking grooves 2043 on the outer wall of the adhesive roller 205, achieving the transmission connection between the rotating rod 2041 and the adhesive roller 205. This ensures that the adhesive roller 205 can rotate with the rotating rod 2041. The same adhesive roller 205 is rotatably connected to adjacent sides of the outer walls of the two through rings 201. The adhesive roller 205 utilizes its own adhesive properties... The adhesive roller 205 has a groove 2043 on its outer wall. The groove 2043 cooperates with the locking block 2042 on the rotating rod 2041 to realize the transmission connection between the adhesive roller 205 and the rotating rod 2041, ensuring that the adhesive roller 205 can rotate normally. A pressing component 206 is provided on the right side of the outer wall of the bracket 1. The pressing component 206 is used to adjust the pressure between the rotating rod 2041 and the bracket 1 to ensure that the position of the adhesive roller 205 is accurate. Specifically, the outer wall of the rotating rod 2041 is slidably connected to the inner wall of the two through rings 201, so that the locking block 2042 on the rotating rod 2041 corresponds to the inner wall of the through ring 201. Then, the sticking roller 205 is placed between the two through rings 201, so that the locking groove 2043 on the outer wall of the sticking roller 205 is aligned with the locking block 2042 on the rotating rod 2041. The rotating rod 2041 is passed through the two through rings 201 and the through rings 201 to ensure that the sticking roller 205 can rotate with the rotation of the through rings 201 and the rotating rod 2041. Then, the clamping assembly 206 is installed on the right side of the outer wall of the bracket 1. By adjusting the clamping assembly 206, the sticking roller 205 maintains a suitable position and pressure during rotation to ensure good contact with the cutter roller 403.

[0019] See attached document Figure 1 Appendix Figure 2 and attached Figure 4 The vacuuming mechanism 6 includes a suction pipe 601, the outer wall of which is fixedly connected to the inner wall of the bracket 1. The suction pipe 601 serves as a channel for airflow and dust transport, providing a flow path for the vacuuming process. A vacuum hood 602 is connected to the left side of the suction pipe 601, increasing the vacuuming area and enabling more effective collection of dust from the surface and surrounding area of ​​the sticky roller 205. A fan 603 is fixedly connected to the inner wall of the suction pipe 601, providing power to create a negative pressure airflow within the suction pipe 601, driving dust into the vacuuming mechanism 6. A dust collection box 604 is fixedly connected to the top of the side plate 5, storing the collected dust and achieving separation and storage of dust from the airflow. The bottom of the suction pipe 601... The suction pipe 601 is connected to the top of the dust collection box 604. This connection structure allows the airflow carrying dust to smoothly enter the dust collection box 604. The suction pipe 601 is equipped with a turbulence component 605. The turbulence component 605 optimizes the airflow state, improves the dust conveying efficiency and protects the fan 603. The turbulence component 605 includes a conical cylinder 6051. The outer wall of the conical cylinder 6051 is fixedly connected to the inner wall of the suction pipe 601. The conical cylinder 6051 accelerates the airflow speed by narrowing the channel cross-section, which enhances the dust entrainment capacity. The inner wall of the suction pipe 601 is fixedly connected to a dustproof plate 6052. The dustproof plate 6052 blocks dust from directly entering the fan 603, reduces the wear of dust on the fan 603 and extends its service life. Specifically, when this device is working, the fan 603 starts to form a negative pressure airflow in the suction pipe 601. The dust suction hood 602, which is connected to the left side of the suction pipe 601, is located near the sticky roller 205 on the inner wall of the bracket 1. Under the action of negative pressure, the dust on the surface and around the sticky roller 205 is sucked in. After the dust enters the suction pipe 601 with the airflow, the conical cylinder 6051 of the turbulence component 605 narrows the airflow channel due to its conical structure, which speeds up the airflow, improves the dust conveying efficiency, and prevents deposition. At the same time, the dustproof plate 6052 on the inner wall of the suction pipe 601 blocks the dust from entering the fan 603 and protects the blades of the fan 603. The accelerated airflow carries the dust around the dustproof plate 6052 and enters the dust collection box 604 at the top of the side plate 5 along the suction pipe 601. The dust settles in the dust collection box 604 under the action of gravity, thus achieving separation from the airflow.

[0020] See attached document Figure 2 Appendix Figure 3 and attached Figure 5 The cutting mechanism 4 includes a servo motor 401, the bottom of which is fixedly connected to the top of the mounting plate 3. The servo motor 401 serves as a power source, providing stable and adjustable power output to the entire cutting mechanism 4. A transmission shaft 402 is fixedly connected to the output end of the servo motor 401, transmitting the power from the servo motor 401 to drive the cutter roller 403 and transmission assembly 404. The cutter roller 403 is fixedly connected to the outer wall of the transmission shaft 402, cutting the material through rotation. A transmission assembly 404 is provided on the outside of the transmission shaft 402, transmitting the power from the transmission shaft 402 to the dust-adhesive mechanism 2, achieving reasonable power distribution and transmission. The transmission assembly 404 includes a first gear 4041, the inner wall of which is fixedly connected to the outer wall of the transmission shaft 402, and a second gear 4042 meshing with the outer wall of the first gear 4041. The inner wall of gear 2 4042 is fixedly connected to the outer wall of the left through ring 201. Gear 2 4042 cooperates with gear 1 4041 to transmit power to the left through ring 201, driving the dust sticking mechanism 2 to run, so that the left through ring 201 can rotate under the drive of gear 2 4042, thereby driving the sticking roller 205 to work. The pressing assembly 206 includes an isolation disk 2061. The inner wall of the isolation disk 2061 is rotatably connected to the outer wall of the rotating rod 2041. The isolation disk 2061 plays the role of isolation and support, reducing the direct friction between the bracket 1 and the screw ring 2063. Multiple balls 2062 are rotatably connected to the inner wall of the isolation disk 2061. The balls 2062 further reduce the rotational resistance between the isolation disk 2061 and the rotating rod 2041, making the rotating rod 2041 rotate more smoothly. The right end of the rotating rod 2041 is threadedly connected to the screw ring 2063. The screw ring 2063 is threadedly connected to adjust the position of the rotating rod 2041. Specifically, when the rotary die-cutting machine is working, the cutting mechanism 4 acts as the power core to drive the dust removal process. After the servo motor 401 starts, its output end drives the transmission shaft 402 to rotate. The cutter roller 403, which is fixedly connected to the outer wall of the transmission shaft 402, rotates accordingly to perform the die-cutting task. At the same time, the transmission component 404 outside the transmission shaft 402 plays a transmission role. Gear 1 4041 is fixed to the outer wall of the transmission shaft 402 and meshes with gear 2 4042. Gear 2 4042 is fixed to the outer wall of the left through-ring 201. When the transmission shaft 402 rotates, the meshing of gear 1 4041 and gear 2 4042 drives the left through-ring 201. Rotating, the left-side through-ring 201, with the help of the rotating component 204, causes the sticking roller 205 to rotate, so as to remove dust from the cutter roller 403. The clamping component 206 ensures the installation of the sticking roller 205 is secure. The inner wall of the isolation disc 2061 is rotatably connected to the outer wall of the rotating rod 2041. Multiple balls 2062 are installed on the inner wall of the isolation disc 2061 to reduce rotational friction. The screw ring 2063 is threadedly connected to the right end of the rotating rod 2041. By screwing the screw ring 2063, the position of the isolation disc 2061 is adjusted, thereby changing the pressure between the rotating rod 2041 and the bracket 1, ensuring that the sticking roller 205 can tightly adhere to the cutter roller 403, effectively removing dust and improving the dust removal effect.

[0021] Working Principle: When the rotary die-cutting machine is running, the cutting mechanism 4 starts to rotate, which drives the left through-ring 201 to rotate. Since the two through-rings 201 are connected by the rotating assembly 204, the outer wall of the rotating rod 2041 in the rotating assembly 204 is slidably connected to the inner wall of the two through-rings 201. Multiple locking blocks 2042 fixedly connected to the rotating rod 2041 cooperate with the locking grooves 2043 on the outer wall of the sticking roller 205. Therefore, the rotation of the left through-ring 201 will drive the sticking roller 205 to rotate through the linkage of the rotating rod 2041, the locking blocks 2042, and the locking grooves 2043. During the rotation of the sticking roller 205, the larger dust particles on the surface of the sticking roller 205 are first sucked away by the dust suction mechanism 6, initially reducing the amount of dust on the surface of the sticking roller 205 and reducing the sticking roller's viscosity. After initial dust collection, the rotating sticky roller 205 continues to move, its surface contacting the cutter roller 403. Due to its adhesiveness, the sticky roller 205 can remove fine dust from the cutter roller 403, thus achieving dust removal and ensuring the cleanliness of the cutter roller 403, improving the working quality of the die-cutting machine. When the sticky roller 205 has been used for a period of time and its adhesiveness decreases or excessive dust on its surface affects the dust removal effect, the connection structure between the sticky roller 205 and the through ring 201 allows the sticky roller 205 to be easily removed and replaced. The rotating rod 2041 is pulled out from the inner wall of the through ring 201, and the locking block 2042 is disengaged from the locking slot 2043, so that the sticky roller 205 can be removed and replaced with a new sticky roller 205, maintaining the dust removal performance of the dust removal cutter holder. Furthermore, during operation, the fan 603 starts, creating a negative pressure airflow inside the suction pipe 601. The suction hood 602, located on the left side of the suction pipe 601 on the inner wall of the bracket 1 and connected to the suction hood 602, is close to the sticky roller 205. Under the action of negative pressure, the dust on and around the sticky roller 205 is sucked into the suction hood 602. The sucked-in dust enters the suction pipe 601 with the airflow. At this time, the conical structure of the conical cylinder 6051 in the turbulence assembly 605 causes the channel to gradually narrow as the airflow passes through. According to the principles of fluid mechanics, the airflow velocity is increased, and the high-speed airflow can more effectively carry the dust forward. To improve dust conveying efficiency and prevent dust from accumulating inside the suction tube 601, the dustproof plate 6052 fixedly connected to the inner wall of the suction tube 601 blocks dust from directly entering the fan 603, preventing dust from causing wear on the blades of the fan 603, effectively protecting the fan 603 and extending its service life. The dust is carried by the airflow accelerated by the conical tube 6051, bypasses the dustproof plate 6052, and continues to move downward along the suction tube 601, finally entering the dust collection box 604 fixedly connected to the top of the side plate 5. In the dust collection box 604, the dust settles due to gravity and separates from the airflow.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
