Description

Technical Field

[0001] This utility model relates to the field of leather base fabric processing technology, specifically to a lint removal device for leather base fabric processing. Background Technology

[0002] As a key substrate in the production of artificial and synthetic leather, the surface quality of leather base fabric directly affects the yield rate and final product quality of subsequent coating, embossing, and other processes. During the weaving and finishing of leather base fabric, a large amount of loose, disordered fuzz inevitably forms on the fiber surface. If this fuzz is not removed, it will form defects during the coating stage, leading to uneven coating, reduced adhesion, and affecting the appearance, feel, and physical properties (such as tear resistance and abrasion resistance) of the leather products.

[0003] Currently, the industry typically uses methods such as mechanical beating, negative pressure suction, or single-pass adhesive roller cleaning to remove lint from leather base fabrics. Mechanical beating has limited removal efficiency and may cause physical damage to the base fabric; negative pressure suction is ineffective at removing tightly adhered or fine lint and consumes a lot of energy; while single adhesive roller cleaning can remove some loose lint, the removal rate often fails to meet the process requirements of high-end products (e.g., removal rate below 85%) for lint that is firmly bonded to the base fabric or has a random orientation, requiring repeated processing and affecting production efficiency.

[0004] In addition, existing equipment generally suffers from poor adaptability and cannot automatically adjust the optimal distance between the cleaning components and the fabric surface according to changes in the thickness of the leather base fabric. For leather base fabrics of different weights or varieties, frequent machine stops and manual adjustments are required, which reduces the continuity and automation level of the production line.

[0005] Therefore, developing an automated device that can efficiently, adaptively, and collaboratively remove fuzz from the surface of leather base fabrics, and adapt to different production conditions and base fabric specifications, has become an urgent need to improve the quality and production efficiency of leather base fabric products.

[0034] Compared with the prior art, the present invention provides a lint removal device for processing leather base fabric, which has the following beneficial effects:

[0035] 1. This lint removal device for leather base fabric processing integrates three cleaning processes: electrostatic lint removal, adhesive roller brushing, and positive and negative pressure dust removal. This forms a synergistic cleaning process. Through the electrostatic effect generated by the lint removal mechanism, the originally flat or messy lint is oriented and erected, exposing the lint to be cleaned. The high-speed rotating brushing mechanism then adheres to and peels off the erected lint over a large area, effectively removing about 90% of the surface lint and completing the main cleaning task. Finally, the dust removal mechanism uses a unique combination of positive pressure blowing and negative pressure adsorption to thoroughly remove residual lint, especially the fine lint that has been blown up and is floating. This multi-technology linkage significantly improves the lint removal rate of leather base fabric and effectively reduces energy consumption.

[0036] 2. This lint removal device for leather base fabric processing, through the ingenious design of the stabilizing component at the end of the device, using tension springs and moving blocks, ensures that the stabilizing roller always fits tightly against the surface of the leather base fabric roll whose diameter continuously increases during winding. This guarantees stable tension and smooth conveying of the leather base fabric during the winding process, avoids the impact of fabric surface shaking on the cleaning effect, and also ensures a smooth connection between the cleaning section and the winding section.

[0037] 3. This lint removal device for processing leather base fabrics allows for flexible adjustment of the overall height of the processing components via an electric push rod. This enables key components such as the cleaning roller and dust collection trough to quickly adapt to leather base fabrics of different thicknesses, maintaining the optimal working distance and improving the equipment's versatility and production flexibility. Simultaneously, the linkage mechanism drives the cleaning roller and dust removal mechanism to operate synchronously, effectively reducing energy consumption and equipment manufacturing costs. Furthermore, the control mechanism can drive the entire processing component to move along the width of the leather base fabric, achieving comprehensive cleaning of the fabric surface or targeted cleaning of specific areas.

[0050] 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.

[0051] Example 1

[0052] Please see Figures 1-7 As shown, the lint removal device for processing leather base fabric proposed in this embodiment includes a platform assembly 1. The platform assembly 1 includes a platform plate 11 that provides planar support. On both sides of the platform plate 11, there are symmetrically arranged stabilizing side plates 12 with the same length and perpendicular downward. The stabilizing side plates 12 are fixed to the upper part of the external rectangular bracket by bolts, thereby ensuring the stability of the device.

[0053] Both ends of the platform component 1 are equipped with stabilizing components 2. Each stabilizing component 2 includes two sets of adjusting mechanisms 21 symmetrically arranged at one end of the platform plate 11 to ensure stable conveying of the leather base fabric, and a roller mechanism 22 arranged between the two adjusting mechanisms 21 to fit the leather base fabric for conveying.

[0054] Each adjustment mechanism 21 includes an extension plate 211 at one end of a stabilizing side plate 12, and an adjustment groove 212 is provided on the side of the extension plate 211.

[0055] The adjustment mechanism 21 also includes a right-angle plate 213 fixed at one end of the extension plate 211. The right-angle plate 213 is perpendicular to the extension plate 211. A round hole is provided on the vertical surface of the right-angle plate 213. The tail end of the support rod 214 is threaded into the round hole. At the same time, a moving block 215 is movably sleeved on the side of the support rod 214.

[0056] The roller mechanism 22 includes a stabilizing roller 221. Both ends of the roller are provided with connecting buttons 222 that are slidably connected in the adjusting groove 212. At the same time, one end of the connecting button 222 is rotatably connected to the corresponding moving block 215 through a bearing. This allows the moving block 215 to move horizontally on the side of the support rod 214, thereby driving the stabilizing roller 221 to move simultaneously through the connecting button 222, but without restricting the rotation of the stabilizing roller 221.

[0057] A limit button 216 is fixed to the front end of the support rod 214. A tension spring 217 is movably sleeved on the side of the support rod 214. The two ends of the spring are fixed to the opposite surfaces of the right angle plate 213 and the moving block 215, respectively. The moving block 215 is attached to the limit button 216 at a set position. The tension spring 217 is used to pull the moving block 215 closer to the right angle plate 213, so that the stabilizing roller 221 is pressed against the outside of the wound leather base fabric. As the thickness of the wound leather base fabric gradually increases, the stabilizing roller 221 is in a state of continuous contact with the outside of the leather base fabric, and gradually generates a reverse displacement movement. At the same time, the tension spring 217 is stretched open until the connecting button 222 slides to the limit in the adjusting groove 212. The moving block 215 is attached to the side of the limit button 216. After the leather base fabric is completely released or removed, the tension spring 217 tightens and pulls the moving block 215, so that the stabilizing roller 221 returns to the initial position.

[0058] A roll assembly 3 for winding the leather base fabric is installed on the stabilizing assembly 2 at the tail end of the platform assembly 1. The roll assembly 3 includes a winding roller 31 rotatably connected between two extension plates 211 at either end of the platform plate 11. The winding roller 31 is used to wind the leather base fabric. A winding motor 32 is installed on the back of one of the extension plates 211. Its output end passes through the other side of the extension plate 211 and is fixed to one end of the winding roller 31. The output end of the winding motor 32 has a bidirectional rotation function. During operation, its output end drives the winding roller 31 to rotate, realizing the forward winding and reverse output of the leather base fabric.

[0059] A processing component 4 is movably connected to the platform component 1. The processing component 4 includes a support mechanism 41 for suspending and installing the workpiece and adjusting its height. The support mechanism 41 includes a flat plate 411 suspended above the platform plate 11 and a movable plate 412 with both ends vertically downward. Multiple synchronously operating electric push rods 413 are fixed on the opposite surface of the movable plate 412 and the flat plate 411. The height of the flat plate 411 is adjusted by the extension and retraction of the output end of the electric push rod 413, thereby setting the distance between the workpiece (mechanism) installed on the flat plate 411 and the leather base fabric on the platform plate 11, which can be adapted to leather base fabrics of different thicknesses.

[0060] Multiple functional mechanisms are installed on the support mechanism 41, namely:

[0061] The pile-up mechanism 42 for generating electrostatic adsorption function includes an electrostatic electrode plate 421 fixed at one end of the top of the flat plate 411 along its length, and a contact plate 422 fixed at one end of the bottom of the flat plate 411 along its length. The contact plate 422 is connected to the electrostatic electrode plate 421. The electrostatic electrode plate 421 is used to generate static electricity and feed it back to the contact plate 422. The contact plate 422 generates static electricity on the surface of the bottom leather base fabric in a non-contact state, causing the pile on the surface of the leather base fabric to stand up.

[0062] A brush mechanism 43 is used to adhere the lint on the surface of the leather base fabric. The brush mechanism 43 includes a roller brush groove 431 in the middle of the top of the flat plate 411 and opened along its length. A cleaning roller 432 is rotatably connected in the roller brush groove 431. When the cleaning roller 432 rotates, it adheres to the surface of the leather base fabric to adhere to and remove the upright lint, thereby achieving the removal of 90% of the lint on the surface of the leather base fabric.

[0063] The brushing mechanism 43 also includes scraping teeth 433 arranged on both sides inside the roller brush groove 431. The scraping teeth 433 are attached to the side of the cleaning roller 432. After the cleaning roller 432 sticks to the hair, it removes the hair from the surface of the roller by separating from the scraping teeth 433 above, so that the cleaning roller 432 can continue to operate.

[0064] The drive mechanism 44 for controlling the operation of the brush mechanism 43 includes a drive motor 441 fixed to one end of the top of the flat plate 411, a drive gear 442 fixed to the output end of the drive motor 441, and a transmission gear 443 fixed to one end of the cleaning roller 432. The drive gear 442 and the transmission gear 443 are meshed by a transmission toothed belt 444 on their sides. When the drive motor 441 is operating, its output end drives the drive gear 442 to rotate, and the meshing force of the transmission toothed belt 444 drives the transmission gear 443 to rotate, thereby causing the cleaning roller 432 to rotate.

[0065] A dust removal mechanism 45 is used for dust and hair removal using positive and negative pressure. The dust removal mechanism 45 includes a dust collection groove 451 at one end of the bottom of a flat plate 411 and a dust collection groove 451 opened along its length. The dust collection groove 451 is connected to a roller brush groove 431. A dust blowing pipe 452 is fixed at one end between two movable plates 412 by a threaded connection. The top of the dust blowing pipe 452 has a linear air knife opening along its length. The dust blowing pipe 452 and the dust collection groove 451 are connected by a hose. When the dust blowing pipe 452 blows air outward (positive pressure), the air in the dust collection groove 451 is drawn away through the hose, thereby allowing the dust collection groove 451 to suck away the lint on the leather base fabric (negative pressure).

[0066] It should be further explained that the dust blowing pipe 452 is equipped with a filter and multiple sets of fan components. When the fan components rotate, they collect air into the dust blowing pipe 452 to form a positive pressure, which is then discharged from the air knife at the top and blown onto the leather base fabric. The collected air comes from the dust suction groove 451 and the connected roller brush groove 431 at the other end of the hose, which creates a negative pressure inside the two grooves to remove the lint from the surface of the leather base fabric. Before being discharged again through the hose into the dust blowing pipe 452, the air is filtered out by the filter components, and only the air is discharged.

[0067] The dust removal mechanism 45 also includes a limiting groove 453 opened along the length of the side of the stabilizing side plate 12. The dust blowing pipe 452 is slidably connected in the limiting groove 453. The diameter of the pipe body matches the width of the groove, which effectively supports the pipe body. At the same time, it ensures the stability of the pipe movement when the processing component 4 moves on the platform plate 11.

[0068] The linkage mechanism 46 for kinetic energy transmission includes an adjustment groove 461 symmetrically opened at one end between two movable plates 412. An electric telescopic rod 462 is fixed at one end of the adjustment groove 461, and a sliding button 463 is fixed at one end of the electric telescopic rod 462. The sliding button 463 is slidably connected in the adjustment groove 461, and an adjustment gear 464 is rotatably connected to one end of the sliding button 463. The output end of the electric telescopic rod 462 drives the sliding button 463 to slide in the adjustment groove 461, causing the adjustment gear 464 to move, thereby adjusting the tension of the linkage belt 468.

[0069] The linkage mechanism 46 also includes a rotating rod 465 fixed to one end of the cleaning roller 432. The rotating rod 465 passes through the side of the flat plate 411 and is fixed with a synchronous gear 466. When the synchronous gear 466 rotates, it drives the cleaning roller 432 to rotate through the rotating rod 465 to remove hair.

[0070] The linkage mechanism 46 also includes a rotating gear 467 that is rotatably connected to the fan shaft inside the dust blower 452. When the rotating gear 467 rotates, it drives the fan to rotate and collect air.

[0071] The adjusting gear 464, the synchronizing gear 466, and the rotating gear 467 are meshed with a linkage toothed belt 468 on their sides. When the rotating gear 467 rotates, the meshing force of the linkage toothed belt 468 drives the adjusting gear 464 and the synchronizing gear 466 to rotate simultaneously, thereby achieving synchronous operation of the two hair removal methods (hair removal by the cleaning roller 432 and positive and negative pressure hair removal).

[0072] The control mechanism 47, which controls the overall position of the processing component 4 for displacement adjustment, includes a control motor 471 fixed to one end of the moving plate 412. The output end of the control motor 471 has a bidirectional rotation function. Its output end passes through the moving plate 412 and is fixed to the shaft of the control gear 472. The control gear 472 meshes with the tooth profile at the bottom of the limiting slide groove 453. Thus, when the motor is running, the output end drives the control gear 472 to rotate, causing the processing component 4 to translate on the platform component 1, thereby adjusting the processing position.

[0073] The working principle of the lint removal device for leather base fabric processing proposed in this embodiment is as follows: During use, the leather base fabric is pulled so that its front end is fixed to the side of the take-up roller 31 and the leather base fabric is attached to the platform plate 11. At this time, the electric push rod 413 is controlled to move, so that the flat plate 411 moves down until the cleaning roller 432 is attached to the upper surface of the leather base fabric. At the same time, the output end of the electric telescopic rod 462 pulls the sliding button 463 to tighten the linkage toothed belt 468 engaged on the side, so that the toothed belt fully covers the three gears (the side of the adjusting gear 464, the synchronous gear 466, and the rotating gear 467). At this time, the take-up motor 32 is controlled to operate, driving the take-up roller 31 at low frequency. The machine rotates at a constant speed in the forward direction to wind up the leather base fabric. At the same time, it controls the operation of the pile-up mechanism 42, so that the static electrode plate 421 generates static electricity, which is then generated on the surface of the leather base fabric downward through the contact plate 422, causing the pile on the surface of the leather base fabric to stand upright. The drive mechanism 44 is controlled to operate, so that the drive motor 441 drives the cleaning roller 432 to stick to the upright pile, and the sticky pile is scraped off by the scraper teeth 433. The cleaning roller 432 continues to stick and remove the pile, removing 90% of the pile on the surface of the leather base fabric. At the same time, the positive and negative pressure technology of the dust blowing pipe 452 and the dust suction tank 451 is used to remove the remaining pile on the leather base fabric again by blowing from below and suctioning from above.

[0074] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
