Description

Technical Field

[0001] This application relates to the technical field of leather punching processing equipment, and more specifically, to a roller-type leather punching processing device. Background Technology

[0002] Leather punching technology is widely used in processing ventilation holes, decorative holes, and positioning holes in leather shoes, hats, bags, clothing, automotive interiors, and home furnishings. Currently, mainstream punching equipment in the industry adopts a vertical reciprocating punching structure, relying on a cylinder or servo motor to drive the punching cutter up and down to complete the punching. This type of structure is an intermittent punching method and has inherent structural defects.

[0003] First, traditional stamping punching has a reciprocating impact stroke, and the mechanical action has a speed limit, so the punching frequency cannot be further increased, making it difficult to adapt to the continuous production needs of high-speed production lines. Second, high-frequency impact operation has large vibration and high noise, and the tool is prone to loosening, displacement and wear. The punched finished products are very prone to defects such as burrs, tears, indentations and hole position displacement. Moreover, most existing punching tools are single-row or double-row structures, which result in a small number of punches per batch, low processing efficiency, and difficulty in ensuring production efficiency and product yield.

[0004] In conclusion, how to improve the production efficiency of leather punching is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a roller-type leather punching processing equipment to effectively improve the production efficiency of leather punching processing.

An embodiment of this application discloses a roller-type leather punching processing device.

[0036] The core of this application is to provide a roller-type leather punching processing device.

[0037] Please refer to Figure 1 and Figure 2 .

[0038] The roller-type leather punching processing equipment provided in this application includes a frame 1 and a rolling punching mechanism. A horizontally arranged placement table 11 is mounted on the top of the frame 1. The placement table 11 is used to lay and support the leather material 5 to be processed. The surface of the placement table 11 is kept flat and smooth, and it can be adapted to the flat placement and continuous conveying of sheet leather 5 and roll leather 5. Conveyor rollers are provided on the frame 1 and at both ends of the placement table 11. The conveyor rollers are used to control the movement of the leather 5, so that the leather 5 can move laterally, thereby ensuring that different positions of the leather 5 are within the processing area of ​​the rolling punching mechanism.

[0039] The rolling punching mechanism is arranged above the table 11 and is used to perform continuous punching operations on the leather 5 laid flat. The rolling punching mechanism includes a moving frame 2, processing rollers 3 and several processing tools 4.

[0040] The movable frame 2 and the frame 1 are connected by a sliding rail and slider structure to achieve relative sliding assembly. The frame 1 is equipped with an electric slide table for driving the movable frame 2 to move. The sliding direction of the movable frame 2 is parallel to the table surface of the placement table 11 and can move along the conveying direction of the leather 5.

[0041] The processing roller 3 is rotatably mounted on the movable frame 2. The rotation axis of the processing roller 3 is parallel to the surface of the placement table 11 and perpendicular to the movement direction of the movable frame 2. Multiple processing tools 4 are evenly fixedly mounted on the surface of the processing roller 3. The end of the processing tool 4 away from the processing roller 3 is the processing end, which can directly and closely contact the surface of the leather 5 laid flat on the placement table 11. The punching operation of the leather 5 is completed by the rolling and pressing of the roller. In the specific implementation process, a circular cutting edge is provided at the end of each processing tool 4, that is, a single contact between a single processing tool 4 and the leather 5 can form a circular hole in the leather 5.

[0042] During one movement of the moving frame 2, the processing roller 3 rolls multiple times, and each processing tool 4 punches the leather 5 multiple times. The efficiency is much higher than the single-hole processing mode of vertical reciprocating stamping. Moreover, the roller's operation process is without impact, vibration, or noise. It can be adapted to continuous feeding of leather 5 rolls and high-speed processing without interruption, thus improving the overall processing efficiency of the production line.

[0043] The roller-type leather punching equipment provided in this application will now be described in more detail with reference to the accompanying drawings and specific embodiments.

[0044] In one specific implementation, reference is made to... Figures 2-5 .

[0045] Specifically, multiple processing tools 4 are arranged in a multi-ring circular array on the surface of the processing roller 3. Each ring of processing tools 4 is evenly distributed around the circumference of the processing roller 3, and the processing tools 4 of adjacent rings are staggered around the circumference of the processing roller 3. This arrangement ensures that adjacent rows of holes formed in a single processing operation are also staggered, increasing the uniformity of perforation on the surface of the leather 5.

[0046] In this embodiment, four rings of machining tools 4 are arranged on the machining roller 3, with 28 machining tools 4 in each ring.

[0047] Based on any of the above embodiments, refer to Figures 1-5 .

[0048] Specifically, the movable frame 2 is equipped with a first driver 22, and a lifting block 23 is slidably mounted on it. The sliding direction of the lifting block 23 is perpendicular to the surface of the placement table 11, realizing vertical lifting adjustment. The processing roller 3 is rotatably connected to the lifting block 23. The first driver 22 drives the lifting block 23 to rise and fall vertically, which can precisely adjust the distance between the processing roller 3 and the surface of the placement table 11, as well as control whether the processing tool 4 and the leather 5 are in contact.

[0049] In actual processing, the pressing height of the processing roller 3 can be flexibly adjusted according to the differences in thickness and hardness of different leathers 5, to adapt to the punching processing of different materials such as thin flexible leather 5 and thick hard leather 5, ensuring consistent punching depth and regular hole shape.

[0050] Based on this, an adjusting block 21 is slidably mounted on the movable frame 2. The sliding direction of the adjusting block 21 is parallel to the table surface of the placement platform 11 and perpendicular to the moving direction of the movable frame 2. The first driver 22 is mounted on the adjusting block 21, and the lifting block 23 is vertically slidably connected to the adjusting block 21. By sliding the adjusting block 21 horizontally, the lifting block 23 and the processing roller 3 can be driven to change their lateral position as a whole, so as to adjust the processing position of the processing tool 4 on the leather 5 and adapt to the punching processing requirements of different width areas of the leather 5.

[0051] The movable frame 2 is equipped with a controller (not shown in the figure) for controlling the movement of the adjusting block 21. The controller can be an electric slide or a chain drive system, etc.

[0052] Furthermore, a second driver 24 and a reset switch 25 are mounted on the lifting block 23. The second driver 24 can drive the machining roller 3 to rotate, and the reset switch 25 is used to detect the circumferential angle position of the machining roller 3.

[0053] After the moving frame 2 carries the processing roller 3 for one processing stroke, the lifting block 23 moves to separate the processing tool 4 from the leather 5. Then, the adjusting block 21 moves laterally to change the position of the processing roller 3 along the width direction of the leather 5. At the same time, the moving frame 2 returns to the initial position. Under the feedback adjustment of the reset switch 25, the second driver 24 makes the processing roller 3 rotate to the initial angle. Then, the lifting block 23 descends to make the processing tool 4 contact the leather 5 again and start the next processing stroke.

[0054] This ensures that the punching position of the processing tool 4 in each stroke is accurately aligned, and that the position of each row of holes formed on the leather 5 is consistent with the position of the holes processed in the previous stroke, thus avoiding problems such as misaligned holes and uneven punching caused by the rotation of the roller.

[0055] In the specific implementation process, the first driver 22 is a motor and a lead screw installed on the adjusting block 21. The lifting block 23 is threadedly connected to the lead screw, and the adjusting block 21 is provided with a vertical guide rail for the sliding engagement of the lifting block 23. The second driver 24 is a drive motor 241 and a synchronous belt 242 installed in the lifting block 23. The drive motor 241 outputs torque to the processing roller 3 through the synchronous belt 242. The second driver 24 only works during the lifting and resetting of the processing roller 3. When punching the leather 5, the second driver 24 is not activated. At this time, the processing roller 3 only rotates passively by the friction between the processing tool 4 and the leather 5, thereby improving the consistency between the rotational speed of the processing roller 3 and the moving speed of the moving frame 2 relative to the leather 5.

[0056] Based on any of the above embodiments, refer to Figure 4 and Figure 6 .

[0057] Specifically, the machining tool 4 is in the shape of a cylindrical tube and adopts an integrated carbide tool structure. The cutting edge of the machining tool 4 is set at the end away from the machining roller 3. The cutting edge is circular and the tip of the cutting edge faces the radial direction of the machining roller 3, so that regular circular punches can be processed, which is suitable for the mainstream circular ventilation hole processing needs in the industry.

[0058] The processing tool 4 has a through-type waste discharge channel 41 inside. One end of the waste discharge channel 41 is set at the center of the circular blade to guide the leather waste 5 generated by punching in real time. The other end of the waste discharge channel 41 can be opened on the side wall of the processing tool 4 and / or at the end facing the processing roller 3 to realize the rapid discharge of waste, avoid the accumulation of waste in the hole, and prevent the waste from squeezing and causing defects such as leather 5 indentation and hole deformation.

[0059] Based on the above embodiment, a first waste outlet 42 is opened on the side wall of the processing tool 4. The first waste outlet 42 is connected to the internal waste discharge channel 41. The first waste outlet 42 is located on the side wall opposite to the rotation direction of the processing roller 3. During the rolling punching process of the processing roller 3, the cutting edge penetrates the leather 5 as the roller rotates. The waste generated during punching enters the waste discharge channel 41 from the center of the cutting edge and can then be quickly discharged from the first waste outlet 42 on the rear side. The inertia of the roller rotation helps to improve the waste discharge efficiency, avoids waste residue clogging the channel, and ensures the continuous and stable operation of the punching operation.

[0060] In another embodiment, or based on the above embodiment, a second waste outlet 43 is provided at one end of the machining tool 4 facing the machining roller 3. The second waste outlet 43 is coaxially connected with the waste discharge channel 41, and the waste can also be discharged vertically upward from the second waste outlet 43 along the waste discharge channel 41, resulting in a better waste discharge effect.

[0061] Based on the above embodiments, such as Figure 4 and Figure 7 As shown, the processing roller 3 adopts a hollow structure, which includes a wheel core 31 and a wheel ring 32 that are coaxially fixed to each other. A hollow cavity is reserved between the wheel core 31 and the wheel ring 32 to form a waste discharge cavity 33. The waste discharge cavity 33 is connected to the external space through the two end faces of the processing roller 3.

[0062] The processing tool 4 is fixed to the surface of the wheel ring 32 by a detachable threaded connection or snap-fit ​​connection, which facilitates the replacement and maintenance of the tool after wear. In this embodiment, the end of the processing tool 4 is provided with an external thread, and the wheel ring 32 is provided with multiple threaded holes for the processing tool 4 to be screwed in. The threaded holes are through holes, so that after the two are connected, the second waste outlet 43 of the processing tool 4 can communicate with the waste discharge chamber 33. The waste generated by punching can enter the waste discharge chamber 33 through the waste discharge channel 41, and finally be discharged from the end face of the processing roller 3 to the outside, falling on the leather 5 or the table of the placement table 11.

[0063] To improve discharge efficiency and effectiveness, the circumferential surface of the wheel core 31 is designed as a slope that is high in the middle and low on both sides, thereby guiding the waste falling on the circumferential surface of the wheel core 31 outward and improving the waste discharge rate.

[0064] Based on any of the above embodiments, refer to Figure 8 and Figure 9 .

[0065] Specifically, the surface of the placement platform 11 is evenly provided with several adsorption holes 12, the axis of the adsorption holes 12 is vertical, the frame 1 is provided with adsorption pipes 13, and the adsorption pipes 13 are connected to a negative pressure fan (not shown in the figure), which can generate a continuous negative pressure suction inside the adsorption holes 12 when working.

[0066] A flexible, breathable mat 14 is laid on the surface of the placement table 11, completely covering the area of ​​the suction holes 12 on the surface of the placement table 11. When the leather 5 is laid flat on the surface of the breathable mat 14, the negative pressure suction can tightly adhere and fix the leather 5 to the upper surface of the breathable mat 14, effectively improving the problems of slippage, wrinkling, and lifting of the leather 5 during processing.

[0067] After the cutting edge of the processing tool 4 penetrates the leather 5, it inserts into the breathable pad 14. Since the breathable pad 14 is made of a flexible material, the cutting edge will not cause any damage to the breathable pad 14 that would affect its use. In this embodiment, the breathable pad 14 is made of breathable felt.

[0068] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
