Technical Field

[0001] This utility model relates to the technical field of napping equipment, specifically a napping equipment for wet napping process of leather-based fabric. Background Technology

[0002] The wet napping process for leather base fabric is a technique that uses mechanical force to create a nap on the surface of the leather base fabric. This process typically includes multiple steps such as rinsing, dyeing, washing, dehydration, rolling, opening, napping, and setting. The napping step is the core step; it uses napping equipment to treat the leather base fabric, creating a fuzzy surface that improves its softness, warmth, and aesthetics.

[0003] This application focuses on researching and improving the napping equipment in the wet napping process of leather-based fabrics. In the existing technology, the core component of the napping equipment is the napping roller. The napping roller applies high-speed friction or stretch to the fabric, making the nap more obvious and dense. This step can adjust the length and density of the nap to achieve the desired effect. However, the existing napping rollers cannot be quickly replaced as needed. Quick roller replacement can quickly switch production modes, saving time each time the napping roller is replaced and improving production efficiency. Therefore, an improved napping equipment specifically for the wet napping process of leather-based fabrics is needed to address this issue. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a special napping equipment for wet napping process of leather base fabric, including a fixed plate 1. A connecting sleeve 2 is movably arranged on the lower surface of the fixed plate 1 through a bearing. A napping roller 3 is arranged between the connecting sleeves 2. A quick-release mechanism is arranged between the napping roller 3 and the connecting sleeve 2. The quick-release mechanism includes a fixed rod 4, a movable rod 5, an annular groove 6, a groove 7, a locking ball 8, a compression sleeve 9, and a notch 10. Fixed rods 4 are fixedly arranged at both ends of the napping roller 3. A movable rod 5 is movably sleeved on the outer surface of the fixed rod 4. An annular groove 6 is opened on the outer surface of the movable rod 5. Several grooves 7 are evenly opened inside the connecting sleeve 2. The locking ball 8 is movably placed inside the grooves 7. A compression sleeve 9 is sleeved on the outer surface of the connecting sleeve 2. A notch 10 is opened on the inner side wall of the compression sleeve 9.

[0023] A spring 11 is fitted between the surface of the connecting sleeve 2 and the extrusion sleeve 9. The spring 11 can automatically push the extrusion sleeve 9 to reset, so that the notch 10 on the surface of the extrusion sleeve 9 and the engaging ball 8 are misaligned.

[0024] A limiting block 12 is fixedly provided at one end of the fixed rod 4. The limiting block 12 can prevent the movable rod 5 from detaching from the outer surface of the fixed rod 4.

[0025] A transmission block 13 is fixedly installed at one end of the movable rod 5, and a transmission groove 14 is provided inside the connecting sleeve 2. When the movable rod 5 is inserted into the connecting sleeve 2, the transmission block 13 will be inserted into the transmission groove 14. Thus, when the connecting sleeve 2 rotates, it can drive the movable rod 5, the fixed rod 4, and the brushing roller 3 to rotate together.

[0026] A reducer 15 is fixedly installed on one side of the fixed plate 1, and a motor 16 is fixedly installed on the upper end of the reducer 15. The power output shaft of the motor 16 is connected to the connecting sleeve 2 through the reducer 15. The motor 16 can drive the connecting sleeve 2 to rotate, thereby driving the napping roller 3 to rotate. The surface of the napping roller 3 is generally provided with steel needles or hooks. When the napping roller 3 rotates, it can hook, comb or cut the fibers, thus achieving the napping effect.

[0027] Guide rollers 17 are movably mounted on both sides of the upper end of the fixed plate 1 via rotating shafts. The guide rollers 17 allow the fabric that needs to be napped to pass through the lower end of the napping roller 3, so that the napping operation can be performed when the napping roller 3 rotates.

[0028] Working principle: When using this device for the napping process, the fabric passes through the lower end of the napping roller 3 via the guide roller. The surface of the napping roller 3 is usually equipped with steel needles or hooks. When the roller rotates, these steel needles or hooks will hook, comb, or cut the fabric fibers, thereby achieving the napping effect.

[0029] As the device is used, when it is necessary to change to different specifications of the brushing roller 3, this device is equipped with a quick-release structure for rapid replacement. For example... Figure 5 The image shows the installation view of the brushing roller 3. For disassembly, simply pull the compression sleeve 9 first, aligning its surface notch 10 with the engaging ball 8, providing space for the engaging ball 8 to move up and down. Then, pull the movable rod 5 forcefully, causing it to retract on the surface of the fixed rod 4. At this time, the annular groove 6 will compress the engaging ball 8, causing it to retract into the groove 7, thereby releasing the restriction on the annular groove 6. Afterwards, the movable rod 5 can be pulled out of the connecting sleeve 2. The operation on the other side is the same, thus easily completing the disassembly of the brushing roller 3; the process is simple and quick.

[0030] When installing the brushed roller 3, first pull the extrusion sleeve 9 so that its surface notch 10 aligns with the engaging ball 8, providing space for the engaging ball 8 to move. Next, align the brushed roller 3 with the connecting sleeve 2 and pull the movable rod 5 into the connecting sleeve 2. Then, release the extrusion sleeve 9; under the action of the spring 11, the extrusion sleeve 9 will return to its original position and push the engaging ball 8 into the annular groove 6, thus completing the limiting and fixing of the brushed roller 3. Furthermore, during the insertion of the movable rod 5 into the connecting sleeve 2, the transmission block 13 will also be inserted into the transmission groove 14, realizing the power connection of the device. Thus, when the connecting sleeve 2 rotates, it can drive the movable rod 5, the fixed rod 4, and the brushed roller 3 to rotate together. Therefore, the installation process of the brushed roller 3 in this device is also simple and quick.
