Description

Technical Field

[0001] This utility model relates to the field of PU synthetic leather technology, and in particular to a PU synthetic leather texturing device. Background Technology

[0002] In the modern leather processing industry, PU synthetic leather has become one of the main artificial leather materials due to its excellent performance and wide application. PU synthetic leather has good abrasion resistance, softness and environmental protection, and is widely used in the manufacture of clothing, footwear, car seats, furniture and other decorative products. However, PU synthetic leather often needs to be enhanced in appearance and texture through some specific processes during production. One of the most common processing techniques is the texturing process.

[0003] The texturing process primarily uses a special suction effect to create a fine texture or raised / recessed effect on the surface of PU synthetic leather. This process not only enhances the aesthetics and feel of the synthetic leather but also increases its wear resistance and pressure resistance to a certain extent, further improving the competitiveness of PU synthetic leather in the market. The quality of the texturing effect directly affects the product's appearance quality and market value; therefore, how to improve the effectiveness of the texturing process has become a key technical issue in the processing of PU synthetic leather.

[0004] Traditional texturing equipment typically uses a combination of texturing rollers and a vacuum system to adhere PU synthetic leather to the roller surface using suction, thereby creating a texture on the leather surface. However, existing texturing equipment generally suffers from several problems that affect its working efficiency, texturing effect, and stability. These problems manifest in the following aspects:

[0005] 1. Uneven airflow on the texturing roller

[0006] In existing texturing equipment, the surface of the texturing roller is often only partially covered by PU synthetic leather, leaving air leakage in the uncovered areas. This results in unstable air pressure inside the roller. Consequently, the suction power of the roller is affected, and the strength and uniformity of the texturing decrease, failing to achieve the desired texture effect.

[0007] 2. Insufficient suction

[0008] In traditional texturing equipment, the airflow is not concentrated on the part of the texturing roller not covered by PU synthetic leather, resulting in weak suction or even insufficient suction. As a result, the texture effect is unclear and the quality is inconsistent.

[0009] 3. High equipment energy consumption

[0010] To maintain the suction effect of the texturing roller, traditional equipment usually needs to provide a strong airflow, resulting in high energy consumption. At the same time, due to airflow leakage, the system's energy efficiency is further reduced, causing energy waste.

[0011] 4. Inconsistent texture effects

[0012] Because of the different types and qualities of PU synthetic leather, traditional texturing equipment often produces different texture effects when processing different materials. This inconsistency makes it difficult to maintain consistent product quality, affecting production efficiency and the quality of the final product.

[0013] Therefore, it is essential to invent a PU synthetic leather texturing device. Utility Model Content

[0014] To address the aforementioned technical problems, this utility model provides a PU synthetic leather texturing device, which solves the issues of uneven airflow in the texturing roller, insufficient suction due to air pressure leakage, and deviations in texture effect that still exist in existing PU synthetic leather texturing devices. The PU synthetic leather texturing device includes a support frame, a power structure, a texturing roller, an extension bracket, a guide roller, PU synthetic leather, a support plate, and a pressing auxiliary structure. The power structure is fixedly installed at one end of the support frame, and the texturing roller is rotatably installed inside the support frame, connected to the output shaft of the power structure. The extension bracket is fixedly installed on the outside of the support frame, and the guide roller is rotatably installed inside the extension bracket. The PU synthetic leather passes around the texturing roller and between the two sets of guide rollers. The support plate is fixedly installed on the top of the support frame, and the pressing auxiliary structure is fixedly installed inside the support plate.

[0015] The support frame includes a support base plate, side support frames, sliding clearance grooves, positioning frames, and vent sealing structures. The side support frames are fixedly installed at both ends of the surface of the support base plate, and the sliding clearance grooves are respectively opened inside the two sets of side support frames. The positioning frames are fixedly installed on the outside of the side support frames, and the vent sealing structures are fixedly installed on the inside of the positioning frames.

[0016] The downward pressing auxiliary structure includes a drive push rod, a movable seat, a support roller, and a contact pad. The drive push rod is fixedly installed above the support plate, and its telescopic rod extends downward through the support plate. The movable seat is fixedly installed below the telescopic rod of the drive push rod and slidably installed inside the sliding clearance groove. The support roller is rotatably installed inside the two sets of movable seats, and the contact pad is wrapped around the surface of the support roller.

[0017] After passing around the texturing roller and through the guide roller, the PU synthetic leather forms a teardrop-shaped bend; the PU synthetic leather wraps 2 / 3 of the surface of the texturing roller by bending.

[0018] The support frame is a stainless steel metal bracket, and the pore sealing structure is also made of stainless steel. The inner side of this pore sealing structure has a groove with an arc consistent with the texture roller. The pore sealing structure covers 1 / 3 of the texture roller not covered by PU synthetic leather. There is a 1mm gap between the pore sealing structure and the texture roller, serving the following functions: ① Structural support: The support frame is the main load-bearing structure of the equipment, providing stability and physical support for the entire device. It fixes the various parts of the equipment together, ensuring that the components do not shift or get damaged during operation. The support frame is typically made of sturdy materials with sufficient strength to support the weight of the power structure, texture roller, guide roller, and other components; ② Prevention of airflow leakage: When the texture roller is working, it generates suction through internal pores, such as those not covered by the pore sealing structure. The pore-sealing structure prevents airflow leakage by covering the pores of the texturing roller that are not covered by PU synthetic leather. Airflow leakage can cause fluctuations in the low-pressure area within the equipment, thereby reducing the texturing effect. Therefore, the pore-sealing structure can effectively ensure the concentration of airflow and the stability of suction on the texturing roller. ③ Enhanced texturing effect: The suction generated by the texturing roller is through pores, while PU synthetic leather only covers a portion of the surface of the texturing roller. The pore-sealing structure effectively avoids airflow leakage in the uncovered area by sealing the 1 / 3 of pores on the texturing roller that are not covered, ensuring that the suction is concentrated on the part covered by PU synthetic leather, thereby enhancing the texturing effect and enabling the PU synthetic leather to better absorb and texture.

[0019] The support roller inside the pressure-assisted structure is a cylindrical hollow roller, and the contact pad is a soft silicone sleeve. This support roller can reciprocate vertically with the support of a drive push rod, moving close to the PU synthetic leather on the surface of the texturing roller. This has the following effects: ① Enhancing contact pressure: By applying appropriate pressure, the pressure-assisted structure allows the PU synthetic leather to make closer contact with the surface of the texturing roller. This contact pressure helps enhance the adhesion of the texturing roller to the PU synthetic leather, thereby achieving a clearer and more uniform texture effect. Especially in the part where the PU synthetic leather does not completely cover the texturing roller, appropriate pressure can allow the PU synthetic leather to better adhere to the surface of the texturing roller, improving the texturing effect; ② Preventing PU synthetic leather from slipping or wrinkling: During the texturing process, the PU synthetic leather may slip or wrinkle due to airflow, especially without sufficient pressure. The downward pressure auxiliary structure applies appropriate pressure to prevent PU synthetic leather from sliding or wrinkling on the texturing roller, ensuring its stability and improving the accuracy and consistency of the texture; ③ Optimize the adsorption effect of the texturing roller: The pressure provided by the downward pressure auxiliary structure can enhance the adsorption effect of the texturing roller surface on the PU synthetic leather. Especially when there may be gaps or incomplete adhesion between the PU synthetic leather and the texturing roller, appropriate downward pressure can ensure that the PU synthetic leather is in close contact with the texturing roller, thereby increasing the attraction of the texturing roller to the PU synthetic leather and making the texture formation more accurate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The support frame of this utility model has the following functions: ① Structural support: The support frame is the main load-bearing structure of the equipment, providing stability and physical support for the entire equipment.

[0022] It secures the various parts of the equipment together, ensuring that the components do not shift or become damaged during operation. The support frame is typically made of robust materials with sufficient strength to support the weight of the power structure, the texturing roller, the guide roller, and other components; ② Prevents airflow leakage: When the texturing roller is in operation, it generates suction through internal pores, such as areas not covered by the pore sealing structure. The pore sealing structure prevents airflow leakage by covering the pores of the texturing roller not covered by PU synthetic leather. Airflow leakage can cause fluctuations in low-pressure areas within the equipment, thereby reducing the texturing effect. Therefore, the pore sealing structure effectively ensures the concentration of airflow and the stability of suction on the texturing roller; ③ Enhances the texturing effect: The suction generated by the texturing roller is through pores, while PU synthetic leather only covers a portion of the roller's surface. The pore sealing structure effectively prevents airflow leakage in the uncovered areas by sealing the remaining 1 / 3 of the pores, ensuring that suction is concentrated on the portion covered by the PU synthetic leather, thus enhancing the texturing effect and allowing the PU synthetic leather to better adhere and texture.

[0023] 2. The downward pressure auxiliary structure of this utility model has the following functions: ① Enhances contact pressure:

[0024] The pressure-assisted structure applies appropriate pressure to ensure closer contact between the PU synthetic leather and the surface of the texturing roller. This contact pressure enhances the roller's adhesion to the PU synthetic leather, resulting in a clearer and more uniform texture. Especially in areas where the PU synthetic leather doesn't completely cover the roller, appropriate pressure allows for better adhesion, improving the texturing effect. Secondly, it prevents the PU synthetic leather from sliding or wrinkling: During texturing, the PU synthetic leather may slide or wrinkle due to airflow, especially without sufficient pressure. The pressure-assisted structure prevents this by applying appropriate pressure, ensuring stability and improving texture accuracy and consistency. Thirdly, it optimizes the roller's adhesion: the pressure provided by the pressure-assisted structure strengthens the roller's adhesion to the PU synthetic leather. Especially when gaps or incomplete adhesion exist between the PU synthetic leather and the roller, appropriate pressure ensures close contact, increasing the roller's attraction and resulting in more precise texture formation.

[0033] This utility model provides a PU synthetic leather texturing device, comprising a support frame 1, a power structure 2, a texturing roller 3, an extension bracket 4, a guide roller 5, PU synthetic leather 6, a support plate 7, and a pressing auxiliary structure 8, wherein: the power structure 2 is fixedly installed at one end of the support frame 1, and the texturing roller 3 is rotatably installed inside the support frame 1, the texturing roller 3 being connected to the output shaft of the power structure 2; the extension bracket 4 is fixedly installed on the outside of the support frame 1, and the guide roller 5 is rotatably installed inside the extension bracket 4, the PU synthetic leather 6 passing around the texturing roller 3 and passing between the two sets of guide rollers 5; the support plate 7 is fixedly installed on the top of the support frame 1, and the pressing auxiliary structure 8 is fixedly installed inside the support plate 7.

[0034] The support frame 1 includes a support base plate 11, side support frames 12, sliding clearance grooves 13, positioning frames 14, and vent sealing structures 15. The side support frames 12 are fixedly installed at both ends of the surface of the support base plate 11, and the sliding clearance grooves 13 are respectively opened inside the two sets of side support frames 12. The positioning frames 14 are fixedly installed on the outside of the side support frames 12, and the vent sealing structures 15 are fixedly installed on the inside of the positioning frames 14.

[0035] The downward pressing auxiliary structure 8 includes a drive push rod 81, a movable seat 82, a support roller 83, and a contact pad 84. The drive push rod 81 is fixedly installed above the support plate 7, and the telescopic rod of the drive push rod 81 extends downward through the support plate 7.

The support roller 83 is rotatably installed inside the two sets of movable seats 82, and the contact pad 84 wraps around the surface of the support roller 83.

[0036] After passing around the texturing roller 3 and through the guide roller 5, the PU synthetic leather 6 forms a teardrop-shaped bend; the PU synthetic leather 6 wraps 2 / 3 of the surface of the texturing roller 3 by bending.

[0037] The support frame 1 is a stainless steel metal bracket, and the air hole sealing structure 15 is also a stainless steel metal structure. The inner side of the air hole sealing structure 15 has a groove with an arc consistent with the suction roller 3. The air hole sealing structure 15 covers 1 / 3 of the suction roller 3 that is not covered by PU synthetic leather 6. There is a 1mm gap between the air hole sealing structure 15 and the suction roller 3.

[0038] The support roller 83 inside the pressure auxiliary structure 8 is a cylindrical hollow roller, and the contact pad 84 is a soft silicone sleeve. The support roller 83 can reciprocate in the vertical direction with the support of the drive push rod 81, and is close to the PU synthetic leather 6 on the surface of the suction roller 3.

[0039] The advantages of this equipment compared to existing technologies are mainly reflected in the following aspects:

[0040] 1. Improves texturing effect and uniformity

[0041] The introduction of the pore sealing structure 15 effectively prevents airflow leakage in areas of the suction roller 3 not covered by PU synthetic leather 6, ensuring that the airflow is concentrated in the covered part. This design avoids the problem of low pressure rise inside the suction roller 3, which can significantly improve the suction force and ensure that the texture effect is more uniform and clear.

[0042] The downward pressure auxiliary structure 8 applies appropriate pressure to ensure that the PU synthetic leather 6 and the surface of the texturing roller 3 are in closer contact, further enhancing the adsorption force and the uniformity of the texture effect, avoiding material slippage or wrinkling, and improving the stability and quality of the texture processing.

[0043] 2. Optimize energy efficiency and reduce energy consumption

[0044] In the prior art, airflow may leak in the area not covered by the suction roller 3, causing the equipment to require additional energy to maintain low pressure, thereby increasing energy consumption. This equipment effectively seals unwanted airflow leakage through the air hole sealing structure 15, ensuring concentrated airflow and reducing the energy consumption of the equipment.

[0045] Because the suction force on the suction roller 3 is more concentrated and stable, the equipment does not require additional energy to compensate for airflow leakage or pressure unevenness, thus reducing energy consumption.

[0046] 3. Improve work efficiency

[0047] This equipment, through the uniform pressure provided by the downward pressure auxiliary structure 8, ensures that the PU synthetic leather 6 is in stable contact with the texturing roller 3, avoiding uneven texture caused by uneven pressure or slippage. This allows the equipment to process more material in a shorter time, thereby improving production efficiency.

[0048] The pore sealing structure 15 ensures the effectiveness of airflow, avoids suction fluctuations caused by airflow leakage, and further improves the processing speed and stability of the equipment.

[0049] 4. Enhance the adaptability and flexibility of the equipment.

[0050] The design of the downward pressure auxiliary structure 8 allows for flexible adjustment of the pressure to adapt to different types of PU synthetic leather 6 materials and texture requirements. This not only improves the applicability of the equipment but also maintains high stability and effectiveness under different production conditions.

[0051] By adjusting the pressure, this equipment can process a wider variety of materials to meet different production needs, increasing the equipment's versatility and flexibility.

[0052] 5. Reduce equipment damage and extend service life

[0053] In the design of this equipment, the pressure of the downward pressure auxiliary structure 8 can be precisely controlled, avoiding excessive pressure acting on the suction roller 3 and PU synthetic leather 6, thus reducing the problem of equipment damage or PU synthetic leather breakage caused by overpressure.

[0054] The use of the air hole sealing structure 15 also avoids overload of the suction roller 3 due to air leakage, reduces the burden on mechanical parts, and helps to extend the service life of the equipment.

[0055] 6. Reduce material waste during the production process

[0056] By ensuring close contact and effective adsorption between the PU synthetic leather 6 and the texturing roller 3, this equipment can avoid production waste caused by material slippage or unclear texture. This improves material utilization, reduces scrap rate, and minimizes waste of raw materials during the production process.

[0057] 7. Improve product quality and consistency

[0058] While ensuring the texturing effect, this equipment can achieve a more precise and consistent texture processing effect through the stable pressure of the downward pressure auxiliary structure 8 and the precise airflow control of the air hole sealing structure 15.
