Description

Technical Field

[0001] This invention relates to the field of suede processing technology, and more particularly to a device and method for uniformly processing ultrafine fibers for suede. Background Technology

[0002] Suede is a type of imitation leather fabric made from microfiber through special processing. Its core process lies in fiber separation, which involves dissolving the "sea" component in the composite fibers through chemical reduction and physical rubbing, thereby releasing the fine "island" fibers and giving the fabric a soft and delicate feel. Currently, overflow processing equipment is commonly used in industry to process suede fibers for uniform separation. This equipment uses lifting rollers to drive the fabric, which is sewn into a ring shape, to circulate back and forth in the cylinder, and is combined with the spraying and rinsing of the treatment liquid, using chemical hydrolysis and fluid dynamics to achieve fiber separation.

[0003] However, existing suede splitting devices still have shortcomings in practical use. Traditional lifting rollers rely solely on simple physical wrapping angles to generate friction with the fabric. When processing thick or slippery suede, the lifting rollers are prone to relative sliding with the fabric, which not only reduces the fabric's circulation efficiency but also easily causes abrasions on the fabric surface, affecting the quality of the finished product. Secondly, existing equipment usually lacks an effective mechanically assisted kneading structure. The splitting process mainly relies on chemical soaking and liquid rinsing, resulting in slow splitting speed and difficulty in accurately controlling uniformity, which easily leads to incomplete local fiber opening or fiber adhesion. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art mentioned above, and to provide a device and method for uniformizing the splitting of ultrafine fibers for suede.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for uniformly splitting microfibers for suede includes a cylinder, a secondary cylinder connected to the surface of the cylinder via a circulation pipe, an outer cylinder connected to the top of the cylinder, a sealing cover on the top of the outer cylinder, a driving component installed inside the outer cylinder, a fabric lifting roller mounted on the surface of the driving component, a driven rod above the fabric lifting roller, and a rotating rod connected to the surface of the driven rod. Hollow blocks are provided on both ends of the driven rod. A sliding frame is slidably connected inside the hollow block. An adjusting bolt is connected to the bottom end of the sliding frame. Sliding rods are connected to both sides of the sliding frame. A sliding groove is opened on the surface of the hollow block to match the sliding rod.

[0006] Preferably, the driving component includes a motor fixedly installed on the inner wall of the outer cylinder and a driving rod connected to the output end of the motor. The fabric lifting roller is installed on the surface of the driving rod. An anti-slip strip is sleeved on the surface of the driving component. The other side of the anti-slip strip is sleeved on the surface of the driven rod. Anti-slip blocks adapted to the anti-slip strip are provided on the surfaces of both the driving component and the driven rod.

[0007] Preferably, the surface of the rotating rod is fitted with convex balls, which are evenly spaced.

[0008] Preferably, both sides of the inner wall of the outer cylinder are connected to a fixing plate, a connecting rod is connected to the surface of the fixing plate, the other end of the connecting rod is connected to a hollow tube, both sides of the hollow tube are slidably connected to a sliding rod, a connecting spring is connected to the side of the sliding rod closer to the inside of the hollow tube, both ends of the hollow tube are connected to a damping sleeve, the end of the sliding rod away from the hollow tube is connected to a connecting frame, and a pressure roller is sleeved inside the connecting frame.

[0009] Preferably, each group of hollow tubes has two tubes, which are connected by a crossbar. Each group of pressure rollers has two rollers, which are symmetrically arranged in the front and rear directions of the anti-slip strip.

[0010] Preferably, the end of the connecting spring away from the sliding rod is connected to the inside of the hollow tube, and the sliding rod is slidably connected to the inside of the damping sleeve.

[0011] Preferably, a support rod is connected to the surface of the fixing plate, the hollow block is connected to the end face of the support rod, a compression spring is connected to the top of the sliding frame, the top of the compression spring is connected to the top wall of the hollow block, and the adjusting bolt is threaded into the interior of the hollow block.

[0012] Preferably, a fixed frame is connected to the surface of the slide rod, two slide rods are provided and symmetrically arranged on both sides of the fixed frame, a damping ring is connected to the surface of the slide rod, the damping ring is slidably connected inside the slide groove, and the driven rod is rotatably connected inside the fixed frame.

[0013] Preferably, the front and rear ends of the driven rod are rotatably connected to the interiors of two sliding frames, respectively.

[0014] The present invention also provides a method for using the device for homogenizing and splitting microfibers for suede, comprising the following steps: Step 1: Sew the suede fabric to be processed into a ring and place it on the surface of the fabric lifting roller; close the sealing cover to seal the cylinder. Step 2: Adjust the bolts to control the displacement of the sliding frame within the hollow block, thereby adjusting the distance between the driven rod and the fabric lifting roller, so that the compression spring generates appropriate pressure to adjust the friction force on the fabric, and completes the filament homogenization process in conjunction with the treatment liquid delivered by the auxiliary cylinder through the circulation pipe. Step 3: Start the drive unit. The drive rod drives the fabric lifting roller to rotate, and the anti-slip belt drives the driven rod and rotating rod to rotate synchronously. The cooperation between the fabric lifting roller and the driven rod drives the fabric to move in a cycle. At the same time, the convex balls on the surface of the rotating rod beat and rub the moving fabric.

[0015] Compared with the prior art, the present invention provides a device and method for homogenizing the microfiber of suede, which has the following beneficial effects: 1. The suede fabric microfiber splitting and homogenization treatment device adds a rotating rod inside the outer cylinder to assist the fabric lifting roller in driving the fabric to move in a circular motion. The fabric is clamped between the two rollers by a double roller linkage structure. The fabric is moved by physical contact, thereby avoiding the fabric slippage phenomenon caused by insufficient friction due to the lifting roller alone. At the same time, it also greatly reduces the risk of fabric abrasion or breakage caused by relative sliding.

[0016] 2. The suede fabric uses a microfiber splitting and homogenization treatment device. By setting a pressure roller on the transmission path of the anti-slip belt, the pressure roller is continuously pressed against and tightened by the elastic thrust of the connecting spring. This ensures that the anti-slip belt remains taut during long-term high-speed operation, effectively avoiding transmission slippage caused by belt slack.

[0017] 3. The suede fabric uses a microfiber splitting and homogenization treatment device. The distance between the rotating rod and the lifting roller is adjusted by manually rotating the adjusting bolt. During this adjustment process, the damping ring fixed on the surface of the slide rod slides inside the groove on the surface of the hollow block. The friction generated between the damping ring and the groove limits the moving speed and shaking of the fixed frame. This frictional resistance not only improves the stability of the adjustment process, but also ensures the accuracy of the driven rod height adjustment, making the distance between the rotating rod and the lifting roller more precise.

A sliding frame 73 is slidably connected inside the hollow block 72. An adjusting bolt 75 is connected to the bottom end of the sliding frame 73. Sliding rods 77 are connected to both sides of the sliding frame 73. A sliding groove 76 is opened on the surface of the hollow block 72 to slide in accordance with the sliding rod 77.

[0023] Reference Figures 2-4 A device for uniformly splitting microfibers for suede fabric includes a drive unit 51 comprising a motor fixedly installed on the inner wall of an outer cylinder 41 and a drive rod connected to the motor output end. A fabric lifting roller 52 is mounted on the surface of the drive rod. An anti-slip strip 53 is sleeved on the surface of the drive unit 51, and the other side of the anti-slip strip 53 is sleeved on the surface of a driven rod 54. Anti-slip blocks adapted to the anti-slip strip 53 are provided on the surfaces of both the drive unit 51 and the driven rod 54. While the motor drives the fabric lifting roller 52 to rotate, the anti-slip strip 53 drives the driven rod 54 and the rotating rod 55 above to rotate synchronously. The surface of the rotating rod 55 is equipped with convex balls 56, which are evenly spaced and used to physically beat the passing fabric.

[0024] Reference Figures 3-6A device for homogenizing and splitting microfibers for suede includes a cylinder 1. A secondary cylinder 2 is connected to the surface of the cylinder 1 via a circulation pipe 3. The cylinder 1 and outer cylinder 41 are preferably welded from SUS316L high-strength stainless steel to resist corrosion from the strong alkaline environment during the fiber splitting process and withstand high temperature and pressure. The outer cylinder 41 is connected to the top of the cylinder 1, and a sealing cover 42 is provided on the top of the outer cylinder 41. A drive component 51 is installed inside the outer cylinder 41, and a fabric lifting roller 52 is mounted on the surface of the drive component 51. The surface of the fabric lifting roller 52 is coated with a polyurethane wear-resistant coating to increase friction on the fabric while preventing wear on the microfiber material. The suede fabric has a driven rod 54 above the lifting roller 52, and a rotating rod 55 is connected to the surface of the driven rod 54. Furthermore, a fixing plate 61 is connected to both sides of the inner wall of the outer cylinder 41, and a connecting rod 62 is connected to the surface of the fixing plate 61. The other end of the connecting rod 62 is connected to a hollow tube 63. Sliding rods 64 are slidably connected to both sides inside the hollow tube 63. A connecting spring 65 is connected to the side of the sliding rod 64 closest to the inside of the hollow tube 63. Damping sleeves 66 are connected to both ends of the hollow tube 63. A connecting frame 67 is connected to the end of the sliding rod 64 away from the hollow tube 63. A pressure roller 68 is sleeved inside the connecting frame 67.

[0025] Two hollow tubes 63 are arranged in each group, connected by a crossbar 69 to maintain structural stability. Two pressure rollers 68 are arranged in each group, symmetrically positioned in the front and rear directions of the anti-slip belt 53. During operation, the two sliding rods 64, under the elastic force of the connecting spring 65, push the two pressure rollers 68 to keep them firmly in contact with the surface of the anti-slip belt 53. The elastic coefficient of the connecting spring 65 is calibrated according to the pre-tension of the anti-slip belt 53 to ensure normal transmission even when the friction coefficient of the anti-slip belt 53 decreases due to lubrication after the spraying is turned on. The mechanical thrust automatically compensates for the slack of the belt, keeping the anti-slip belt 53 taut.

[0026] The end of the connecting spring 65 away from the sliding rod 64 is connected to the inside of the hollow tube 63. The sliding rod 64 is slidably connected to the inside of the damping sleeve 66 to increase the smoothness of movement. In its natural state, the connecting spring 65 is in an energy storage state and uses its own elastic thrust to push the sliding rod 64 outward.

[0027] Reference Figures 7-8A device for homogenizing and splitting ultrafine fibers for suede includes a cylinder 1. A secondary cylinder 2 is connected to the surface of the cylinder 1 via a circulation pipe 3. The cylinder 1 and outer cylinder 41 are preferably welded from SUS316L high-strength stainless steel to resist corrosion from the strong alkaline environment during the fiber splitting process and withstand high temperature and pressure. The top of the cylinder 1 is connected to the outer cylinder 41, and a sealing cover 42 is provided on the top of the outer cylinder 41. A drive component 51 is installed inside the outer cylinder 41, and a lifting roller 52 is mounted on the surface of the drive component 51. The surface of the lifting roller 52 is coated with a polyurethane coating. The abrasion coating increases the friction on the fabric while preventing wear on the microfiber suede fabric. A driven rod 54 is provided above the lifting roller 52, and a rotating rod 55 is connected to the surface of the driven rod 54. Furthermore, a support rod 71 is connected to the surface of the fixed plate 61, and a hollow block 72 is connected to the end face of the support rod 71. A compression spring 74 is connected to the top of the sliding frame 73, and the top of the compression spring 74 is connected to the top wall of the hollow block 72. An adjusting bolt 75 is threaded into the inside of the hollow block 72 and also threaded into the bottom of the hollow block 72.

[0028] The surface of the slide rod 77 is connected to the fixed frame 79. There are two slide rods 77, which are symmetrically arranged on both sides of the fixed frame 79. The surface of the slide rod 77 is connected to the damping ring 78. The damping ring 78 is slidably connected to the inside of the slide groove 76. The frictional resistance of the damping ring 78 is used to eliminate the shaking gap during the adjustment process. The driven rod 54 is rotatably connected to the inside of the fixed frame 79.

[0029] The front and rear ends of the driven rod 54 are rotatably connected to the interiors of the two sliding frames 73, respectively.

[0030] In this invention, before starting the device, the operator first opens the sealing cover 42 and manually rotates the adjusting bolt 75 with a tool to make it rotate inside the hollow block 72, thereby driving the sliding frame 73 to slide up and down along the slide groove 76. Since the driven rod 54 is rotatably connected inside the sliding frame 73 and the rotating rod 55 is connected to the surface of the driven rod 54, the raising and lowering of the sliding frame 73 directly drives the height change of the driven rod 54 and the rotating rod 55, thereby precisely adjusting the distance between the rotating rod 55 and the lower lifting roller 52. While the operator adjusts the height of the driven rod 54, the driven rod 54 also drives the fixed frame 79 on the surface to move accordingly. At this time, the fixed frame 79 drives the sliding rods 77 on both sides to move, and the sliding rods 77 drive the damping ring 78 on the surface to slide inside the slide groove 76. The friction between the damping ring 78 and the slide groove 76 limits the moving speed of the fixed frame 79, making the adjustment of the height of the driven rod 54 more precise.

[0031] Afterwards, the operator sews the suede fabric to be processed into a ring shape from end to end, places it on the surface of the fabric lifting roller 52, and then closes the sealing cover 42 to create a closed high-temperature and high-pressure processing environment in the cylinder 1.

[0032] At this time, the operator starts the drive unit 51, and the drive rod drives the fabric lifting roller 52 to rotate, pulling the fabric to move in a circular motion within the cylinder 1; at the same time, the drive unit 51 drives the driven rod 54 and the rotating rod 55 above to rotate synchronously through the anti-slip belt 53; at the same time, the connecting spring 65 uses its own elasticity to continuously pull the sliding rod 64 inward, and due to the action of the damping sleeve 66, the sliding rod 64 moves steadily. The sliding rod 64 pulls the two pressure rollers 68 in the connecting frame 67, so that the two pressure rollers 68 abut against the surface of the anti-slip belt 53. Through the continuous thrust applied by the two pressure rollers 68, the anti-slip belt 53 is forced to remain taut at all times, ensuring the stable transmission of power between the drive unit 51 and the driven rod 54.

[0033] During the fabric circulation process, the operator adds treatment liquid into the sub-cylinder 2. At this time, the chemical treatment liquid in the sub-cylinder 2 is transported to the cylinder 1 through the circulation pipe 3 to impregnate and rinse the fabric. At the same time, the convex ball 56 on the surface of the rotating rod 55 rotates rapidly with the rod, and performs high-frequency beating and mechanical rubbing on the fabric passing through the gap between the rotating rod 55 and the lifting roller 52. Through physical rubbing combined with chemical reduction, the dissolution and stripping of the "sea" component in the island fiber is accelerated, thereby achieving efficient and uniform microfiber separation treatment.

[0034] A method for using a device for homogenizing and splitting microfibers for suede, comprising the following steps: Step 1: Sew the suede fabric to be processed into a ring and place it on the surface of the fabric lifting roller 52; close the sealing cover 42 to seal the cylinder 1. Step 2: Adjust the bolt 75 to control the displacement of the sliding frame 73 within the hollow block 72, thereby adjusting the distance between the driven rod 54 and the fabric lifting roller 52, so that the compression spring 74 generates appropriate pressure to adjust the friction force on the fabric, and complete the filament homogenization process in conjunction with the treatment liquid delivered by the auxiliary cylinder 2 through the circulation pipe 3. Step 3: Start the drive unit 51, drive the fabric lifting roller 52 to rotate through the drive rod, and drive the driven rod 54 and the rotating rod 55 to rotate synchronously through the anti-slip belt 53. The cooperation between the fabric lifting roller 52 and the driven rod 54 drives the fabric to move in a cycle. At the same time, the convex balls 56 on the surface of the rotating rod 55 beat and rub the moving fabric.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
