Description

Technical Field

[0001] The utility model belongs to the technical field of embossing, and in particular relates to an embossing device for processing microfiber leather. Background Art

[0002] Microfiber leather, also known as ultrafine fiber polyurethane synthetic leather, is the third generation of artificial leather, following PVC and PU synthetic leather. Its base fabric is made from ultrafine fibers processed through a non-woven process, perfectly simulating the structure of natural leather. As a result, it possesses many superior properties not found in ordinary artificial leather. Its structure is closer to the natural fibers of genuine leather, and in some cases, even surpasses it. During the processing of microfiber leather, embossing is often performed to enhance its aesthetics and feel.

[0003] Currently, microfiber leather is mostly embossed using an integrated embossing roller. However, the surface texture of the embossing roller will suffer significant wear and tear over time. Once damaged, the entire embossing roller must be replaced. Existing embossing rollers require multiple people to install or remove, affecting production efficiency.

[0004] A Chinese utility model with authorization announcement number CN 221142182 U discloses an embossing device for processing microfiber leather, and the utility model relates to the technical field of embossing. The embossing device for processing microfiber leather is characterized in that the knob is turned to drive the first bevel gear to rotate, which in turn drives the second bevel gear to rotate the screw, thereby causing the slider to drive the limit seat to slide along the through slot, so that the left end of the limit seat is disengaged from the right end of the outer roller and the outer side of the engaging block, thereby releasing the limit fixation of the outer roller and the inner roller. The inner roller is rotated to disengage the protrusion at its right end from the inner side of the engaging block, thereby facilitating the disassembly and assembly of the outer roller. The limit slot is aligned with the limit bar, and the outer roller is slidably sleeved on the outer side of the inner roller until the left end of the outer roller is in contact with the limit ring. The inner roller is rotated to engage the protrusion at its right end with the engaging block, thereby achieving quick installation of the outer roller. The knob is then turned to drive the limit seat to slide leftward, so that the engaging block is sleeved on the inner side of the limit seat. At the same time, the left end of the limit seat abuts against the right end of the outer roller, thereby achieving the limit fixation of the outer roller. However, the device is very inconvenient during installation and disassembly. Utility Model Content

[0022] Example 1:

[0023] like Figure 1-Figure 7 As shown, the utility model provides an embossing device for processing microfiber leather, including a base plate 1 and a roller 2. The roller 2 is fixedly mounted with an outer roller 3. The base plate 1 is fixedly mounted with a bearing assembly 5 via a fastener 4. The bearing assembly 5 is movably mounted with a telescopic roller 7. The telescopic roller 7 is fixedly mounted with a gear 8. The telescopic roller 7 is provided with a clamping block 9, a receiving hole 10, and a flange 11. The base plate 1 is fixedly mounted with a drive motor 13 via a support 12. The drive motor 13 is driven and connected to the telescopic roller 7 via a screw 14. Sleeves 15 are provided at both ends of the roller 2, and the sleeve 15 is provided with a clamping groove 16. The roller 2 is provided with a concave hole 17, and a ball bearing 18 is movably mounted in the concave hole 17. An annular handle 19 is provided at both ends of the roller 2. The outer roller 3 is provided with a fixing ring 20, and the fixing ring 20 is fixedly connected to the roller 2 via a bolt 21.

[0024] The cam 14 is provided with a plurality of guide wheels 16, 17 and 18, and the guide wheels 17 are provided with guide wheels 19, 10 and 11. The guide wheels 18 are provided with guide wheels 11, 12 and 13, and the guide wheels 18 are provided with guide wheels 14.

[0025] When disassembling the present invention, two workers are required to hold the two ends of the roller 2 respectively, start the drive motor 13, drive the telescopic roller 7 to retract through the screw rod 14, and pull the telescopic roller 7 out of the sleeve 15 to complete the disassembly process of the roller 2.

[0026] Example 2:

[0027] like Figure 1-Figure 7As shown, the utility model includes a base plate 1 and a roller 2, and the roller 2 is fixedly mounted with an outer roller 3. The base plate 1 is fixedly mounted with a bearing assembly 5 through a fastener 4, and the bearing assembly 5 is movably mounted with a telescopic roller 7, and the telescopic roller 7 is fixedly mounted with a gear 8. The telescopic roller 7 is provided with a clamping block 9, a receiving hole 10 and a flange 11. The receiving hole 10 is used to accommodate a screw 14, and the flange 11 can cooperate with the screw 14 to drive the telescopic roller 7 to move. The base plate 1 is fixedly mounted with a drive motor 13 through a support 12, and the drive motor 13 is driven to connect the telescopic roller 7 through the screw 14. Sleeves 15 are provided at both ends of the roller 2, and the sleeve 15 is provided with a card slot 16. In the processing of microfiber leather, the use of an embossing device is crucial. The outer roller 3 of the embossing device is used to engrave different patterns and emboss the leather. The utility model aims to improve the installation and disassembly efficiency of the roller 2. By adopting a telescopic roller 7 to connect with the roller 2, the installation and disassembly process can be greatly simplified. In actual operation, when installing the roller 2, two workers need to work together to lift the roller 2. The sleeves 15 at both ends of the roller 2 must be aligned with the adjacent retractable roller 7 to ensure a smooth connection. After starting the drive motor 13, the motor drives the retractable roller 7 into the sleeves 15 via the screw 14. The clamping block 9 of the retractable roller 7 tightly engages with the slot 16 in the sleeve 15, ensuring a stable connection between the retractable roller 7 and the roller 2. This allows for rapid installation of the roller 2, thereby improving production efficiency. Disassembly is equally simple. After grasping each end of the roller 2, the worker starts the drive motor 13, which drives the retractable roller 7 backwards via the screw 14. At this point, the retractable roller 7 is pulled out of the sleeves 15, completing the disassembly of the roller 2. Since the entire process requires only two workers, compared to previous methods that required the coordination of multiple personnel, labor costs are significantly reduced and operational flexibility is increased.

[0028] The roller shaft 2 of this utility model is provided with a recessed hole 17, in which a ball bearing 18 is movably mounted. The provision of ball bearing 18 facilitates the insertion and removal of the roller shaft 2, thereby improving installation efficiency. This design allows the outer roller 3 to slide smoothly into the roller shaft 2 during installation, facilitated by ball bearing 18. This makes the connection between the roller shaft 2 and the outer roller 3 faster and simpler, further optimizing the production process and saving production time. The outer roller 3 is provided with a retaining ring 20, which is fixed to the roller shaft 2 via bolts 21. This structure ensures that once the outer roller 3 is inserted into the roller shaft 2, it is secured to the roller shaft 2 via bolts 21. The bolt connection 21 prevents the outer roller 3 from slipping during the embossing process. The outer roller 3 is subjected to significant pressure and friction during operation, so a stable connection is crucial for ensuring effective embossing. Slipping of the outer roller 3 directly affects the depth and uniformity of the embossing, resulting in reduced quality of the microfiber leather product. During the embossing of microfiber leather, the stability of roller 2 is essential for ensuring product quality. A weak connection between outer roller 3 and roller 2 can cause displacement during the embossing process, resulting in unsatisfactory embossing results. This design, through the coordination of a retaining ring and bolts 21, strengthens the connection between outer roller 3 and roller 2, ensuring the aesthetics and feel of the microfiber leather product. In practice, operators can easily remove outer roller 3 by simply loosening bolts 21 when replacing roller 2. This design not only improves roller 2 maintenance efficiency but also reduces potential errors caused by manual docking.

[0029] The roller 2 of the present invention is provided with an annular handle 19 at each end. The provision of these annular handles 19 effectively improves the worker's grip during operation, ensuring a secure grip on both ends of the roller 2 during installation and removal. This enhanced grip stability reduces the risk of slippage or falling during installation and removal, improving work efficiency and safety. Replacing and maintaining the roller 2 is a common and important step in the processing of microfiber leather. When installing and removing the roller 2, operators often need to apply a certain amount of force to securely secure the roller 2 in the embossing device. The design of the annular handles 19 provides a more comfortable and convenient grip for workers. During operation, workers can apply more even force through the handles, reducing accidents caused by an unstable grip. The provision of the annular handles 19 also effectively distributes the pressure applied by workers to the roller 2 during operation. In traditional embossing devices, the roller 2 may lack sufficient gripping structure at both ends, making it difficult for workers to accurately apply force and maintain control during use. The design of the ring handle 19 allows workers to operate in a more natural posture. This humanized design not only improves the comfort of operation, but also effectively reduces the fatigue of workers caused by long-term operation.
