Description

Technical Field

[0001] This invention relates to the field of die-cutting machine technology, and more particularly to a collection device for a roll paper die-cutting machine. Background Technology

[0002] A die-cutting machine is a machine that cuts materials according to a fixed template. Also called a die-cutting machine or CNC punching machine, it primarily relies on a die-cutting blade to apply pressure to the material being cut. It is 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 materials, and mobile phone pads. The die-cutting machine utilizes steel blades, metal molds, and steel wire (or a template carved from steel plate) to apply pressure through a printing plate, cutting printed materials or cardboard into specific shapes. It is an important piece of equipment for post-printing packaging processing. Its principle is that within a fixed mold, the applied pressure causes compression deformation or breakage of the printed paper at the stress points.

[0003] The products of the die-cutting machine are divided into finished products and waste. After die-cutting, the finished products and waste should be collected separately. Due to the difference in cutting force or material, the finished products may sometimes be attached to the waste, causing them to mix together and resulting in waste. Therefore, it is necessary to separate them manually. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings in the prior art by providing a collection device for a roll paper die-cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design a collection device for a roll paper die-cutting machine, including a paper winding wheel for winding and collecting the die-cut paper rolls, the paper winding wheel being mounted on a drive unit, a demolding part for removing the die-cut finished products being provided above the drive unit, and a collection part for collecting the die-cut finished products being mounted on the drive unit, the collection part being arranged opposite to the demolding part.

[0007] Furthermore, the paper winding wheel includes a wheel body, a drive shaft is coaxially mounted on the wheel body, the drive shaft is equipped with a matching motor for providing power, and limit blocks are provided at both ends of the drive shaft.

[0008] Furthermore, the circumferential wall of the wheel body is provided with a plurality of long grooves for inserting the die-cut paper tube, and the wheel body is provided with a fan-shaped groove axially connected to the long grooves, and a drive wheel is provided in the fan-shaped groove for assisting and pressing the die-cut paper tube.

[0009] Furthermore, the drive unit includes a base plate, which is a square plate structure, with a frame for loading the paper winding wheel on top of it, and a groove for mounting the paper winding wheel on the frame.

[0010] Furthermore, the frame is provided with a pushing part on the outside for easy removal of the paper roller, and the pushing part is installed on the upper end face of the base plate.

[0011] Furthermore, the pushing unit includes a motor for providing power. The motor is mounted on the upper surface of the base plate via a bracket. A bolt is installed at the output end of the motor. A fixing sleeve is installed at the end of the bolt away from the motor. The fixing sleeve is fixedly installed on the upper surface of the base plate. A pushing frame is threaded onto the bolt. One side of the pushing frame is in contact with the outer wall of the frame.

[0012] Furthermore, the lower part of the push frame has a double-layer structure with a gap between the two layers, and the push frame is mounted on bolts through the double-layer position.

[0013] Furthermore, the demolding part includes an outer box, which is provided with a partition. The partition has multiple openings, and a fan is installed at each opening. A conical bucket for concentrating airflow is provided on the end face of the partition away from the fan. A sliding plate A and a sliding plate B are provided on the side of the outer box away from the collection part.

[0014] Furthermore, the air outlet of the conical bucket is connected to a flexible hose, and the end of the hose away from the conical bucket is mounted on a movable frame. The outer casing is provided with a slide rail, and the movable frame is mounted on the slide rail.

[0015] Furthermore, the collecting part includes a collecting box, with a collecting port at one end of the collecting box near the demolding part and a discharging port at the other end of the collecting box away from the demolding part, the discharging port being located at the lower part of the collecting box.

[0016] The collection device for a roll paper die-cutting machine proposed in this invention has the following advantages:

[0017] In this invention, a paper winding wheel is used to roll and collect the waste paper tubes after die-cutting. Since the collected paper winding wheel is relatively heavy, the pushing part of this device can be used to disassemble the collected paper winding wheel.

[0018] In this invention, the die-cut finished product can be removed from the paper tube and guided to the collection section through the demolding part. During the demolding process, the airflow can be adjusted by adjusting the air intake of the fan to adapt to paper tubes of different hardness.

[0019] This invention can adjust the direction of the airflow, allowing the air to act directly on the finished product, making demolding more precise. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0032] This application discloses a collection device for a roll paper die-cutting machine, combined with Figure 1As shown, it includes a paper winding wheel 1 for winding and collecting the die-cut paper tubes. The paper winding wheel 1 is cylindrical in shape. The paper winding wheel 1 is mounted on a drive unit 2. A demolding part 3 for removing the die-cut finished products is provided above the drive unit 2. A collection part 4 for collecting the die-cut finished products is mounted on the drive unit 2. The collection part 4 is arranged opposite to the demolding part 3.

[0033] Combination Figure 2 and Figure 3 As shown, the paper winding wheel 1 includes a wheel body 13, which is cylindrical and made of cast iron. Its outer wall is covered with a coating layer to increase friction. The coating layer is made of rubber or silicone. A drive shaft 11 is coaxially mounted on the wheel body 13 and is connected by a key. The drive shaft 11 can drive the wheel body 13 to rotate. The drive shaft 11 is equipped with a matching motor to provide power. Limit blocks 12 are provided at both ends of the drive shaft 11. The size of the limit blocks 12 is larger than the size of the drive shaft 11.

[0034] Combination Figure 3 As shown, the circumferential wall of the wheel body 13 is provided with a plurality of long grooves 14 for inserting the die-cut paper tube. The length of the long groove 14 is not less than the width of the paper tube. The wheel body 13 is provided with a fan-shaped groove 15 axially connected to the long groove 14. Each long groove 14 is provided with a plurality of fan-shaped grooves 15 connected to it. A drive wheel 16 is provided in the fan-shaped groove 15 to assist and press the die-cut paper tube. A matching motor is provided on the drive wheel 16. The drive wheel 16 is made of rubber. By using the drive wheel 16, when the die-cut paper tube is inserted into the long groove 14, the rotation of the drive wheel 16 can make the die-cut paper tube go deeper into the long groove 14, and the friction of the drive wheel 16 when it rotates can fix the die-cut paper tube inserted into the long groove 14. Example 2

[0035] Based on Example 1, combined with Figure 4 As shown, in this embodiment, the drive unit 2 includes a base plate 21 placed on the ground and fixed to the ground by bolts or concrete. The base plate 21 is a square plate structure, and a frame 22 for loading the paper winding wheel 1 is provided on the top of the base plate. The frame 22 is provided with a groove 23 for installing the paper winding wheel 1. The groove 23 is long and narrow, with one end penetrating through the frame 22. The other end of the groove 23 is provided with an arc-shaped groove for loading the drive shaft 11 and for fixing the position of the drive shaft 11. The size of the arc-shaped groove is not less than the diameter of the drive shaft 11.

[0036] The frame 22 is provided with a pushing part 24 for facilitating the removal of the paper winding wheel 1. The pushing part 24 is installed on the upper end surface of the base plate 21 and is arranged along the direction of the groove 23.

[0037] Combination Figure 5 As shown, the pushing unit 24 includes a motor 241 for providing power. The motor 241 is mounted on the upper surface of the base plate 21 via a bracket. A bolt 242 is installed at the output end of the motor 241. To fix the bolt 242 and prevent it from swinging, a fixing sleeve 244 is installed at the end of the bolt 242 away from the motor 241. The bolt 242 can rotate freely on the fixing sleeve 244. The fixing sleeve 244 is fixedly installed on the upper surface of the base plate 21. A pushing frame 243 is threaded onto the bolt 242. One side of the pushing frame 243 contacts the outer wall of the frame 22. The contact between the pusher 243 and the frame 22 prevents the pusher 243 from rotating during movement, ensuring that the pusher 243 can only move in a straight line along the bolt 242. The rotation of the bolt 242, through the threaded connection, drives the pusher 243 to move, causing the pusher 243 to push out the paper winding wheel 1 in the groove 23. During the pushing process, the pusher 243 contacts the limiting blocks 12 set at both ends of the drive shaft 11. To facilitate the pushing out of the paper winding wheel 1, the upper end of the pusher 243 is inclined. Through the contact of the inclined surface with the limiting block 12, the paper winding wheel 1 can be easily pushed out from the arc-shaped groove on the groove 23.

[0038] To improve the stability of the push frame 243's movement, the lower part of the push frame 243 has a double-layer structure with a gap between the two layers. The push frame 243 is mounted on the bolt 242 through the double-layer position. The double-layer structure of the push frame 243 allows the two layers of the push frame to support each other, preventing tilting when the push frame 243 is under force, thus making the push frame 243 more stable. Example 3

[0039] Based on Example 2, combined with Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the demolding part 3 includes an outer box 31, which is a square frame structure. A partition 35 is provided in the middle of the outer box 31. The partition 35 has multiple openings, and a fan 34 is installed at each opening. A conical bucket 36 for concentrating airflow is provided on the end face of the partition 35 away from the fan 34. The conical bucket 36 can concentrate the airflow emitted by the fan 34, making the airflow more concentrated and stronger, and blowing it onto the die-cut paper tube to blow out the die-cut finished product. A sliding plate A32 and a sliding plate B33 are provided on the side of the outer box 31 away from the collection part 4. The sliding plates A32 and B33 cooperate to close the outer box 31. By sliding the sliding plates A32 and B33 against each other, the air intake area of ​​the outer box 31 can be adjusted, thereby adjusting the airflow of the fan 34.

[0040] To facilitate adjustment of the blowing position, a flexible hose 37 is connected to the air outlet end of the conical bucket 36. The length of the flexible hose 37 is greater than the distance from the air outlet end of the conical bucket 36 to the edge of the outer casing 31. The end of the flexible hose 37 away from the conical bucket 36 is installed on the movable frame 38. The installation method is a transition fit or adhesive bonding. A slide rail 39 is provided on the outer casing 31. The slide rail 39 is elongated. The movable frame 38 is installed on the slide rail 39 and can slide freely on the slide rail 39. The blowing position can be adjusted by sliding the movable frame 38. Example 4

[0041] Based on Example 3, combined with Figure 9 and Figure 10 As shown, in this embodiment, the collecting part 4 includes a collecting box 41. The collecting box 41 is provided with a collecting port 42 at one end near the demolding part 3. The collecting port 42 is opposite to the demolding part 3 and the size of the collecting port is larger than the size of the demolding part 3. The collecting box 41 is provided with a discharge port 43 at the other end away from the demolding part 3. The discharge port 43 is located at the lower part of the collecting box 41. Through the collecting port 42 and the discharge port 43, the finished product blown down by the hose 37 can fall into the collecting port 42. At the same time, under the action of the wind force, the finished product is discharged from the discharge port 43. The space inside the collecting box 41 can effectively reduce the wind force blown out from the hose 37. In order to prevent the collecting box 41 from damaging the paper tube, the upper end of the collecting box 41 is provided with an arc-shaped chamfer.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
