Description

Technical Field

[0001] This invention relates to the field of napping machines, and more particularly to a multi-roller coordinated napping machine for suede napping and its usage method. Background Technology

[0002] Suede, a fabric known for its soft touch, delicate appearance, and excellent performance, is widely used in clothing, home décor, and automotive interiors. As market demands for suede product quality continue to rise, the uniformity, density, length consistency, and loft of the fabric's nap have become core indicators determining product grade. The napping process, a crucial step in suede production, directly impacts the final product's texture and market competitiveness.

[0003] With the advancement of the intelligent and efficient development trend in the textile industry, existing napping equipment can no longer meet the high-quality and high-capacity production needs of suede products.

[0004] Traditional napping machines are not efficient enough, and the fabric is prone to falling off and wrinkling under the high-speed rotation of the napping rollers. At the same time, they cannot effectively collect and process the lint generated during napping. Summary of the Invention

[0005] Purpose of the Invention: The purpose of this invention is to provide a multi-roller collaborative raising machine for suede raising. By optimizing the arrangement structure and collaborative control mechanism of multiple raising rollers, the raising efficiency of suede fabric is improved, meeting the market demand for high-quality suede products. This solves the problems of low efficiency and unstable raising quality of traditional single-roller and double-roller raising machines, as well as the easy shedding and wrinkling of fabrics under high-speed rotation of the raising rollers. It ensures the dimensional stability and appearance of suede fabric, further enhancing the market competitiveness of the product. Another purpose of this invention is to provide a multi-roller collaborative raising machine for suede raising that, while achieving efficient and high-quality raising, integrates a lint collection and treatment function. By setting targeted lint adsorption at corresponding positions of the raising mechanism, it effectively collects the lint generated during the raising process, avoiding lint accumulation that affects the stability of equipment operation and fabric cleanliness, reducing lint fly, improving the production environment, and reducing the process cost of subsequent fabric cleaning. This aligns with the intelligent and efficient development trend of the textile industry and makes up for the shortcomings of existing raising equipment in lint treatment.

[0016] Furthermore, two fixing blocks are fixedly connected to the lower sides of both sides of the clamping plate, and racks are fixedly connected to the lower and upper sides of the opposite sides of the two fixing blocks.

[0017] Furthermore, a handle three is provided on the front surface of the clamping plate located in front of the discharge port. An elastic airbag is fixedly connected to the inner side of the handle three. A notch is opened on the rear surface of the clamping plate located in front of the discharge port. A pneumatic telescopic tube is fixedly connected to the rear surface of the handle three and the inner side of the notch. The pneumatic telescopic tube and the notch are rotatably connected by a rotating shaft. A limit plate is fixedly connected to the rear end of the pneumatic telescopic tube. Multiple springs two are fixedly connected between the limit plate and the notch. An air exchange tube is fixedly connected between the pneumatic telescopic tube and the elastic airbag.

[0018] According to another aspect of the present invention, a method for using a multi-roller synergistic napping machine for suede napping is provided, comprising the following steps:

[0019] S1. Equipment Preparation: The operator opens the box door 2 through handle 2, places the appropriate lint collection bag directly below the discharge port, ensuring that the opening of the collection bag completely covers the discharge port, then closes the box door 2, and checks whether the protective cover is tightly engaged with the outer side of the toothed ring on the left side of the machine box; at the same time, the operator holds the handle 3 on the clamping plate in front of the discharge port, pulls the clamping plate forward, the clamping plate slides along the slide rod and stretches the spring 1, the front clamping plate drives the rack to move through the fixing block 2, the rack meshes with the gear 2 and drives the rear clamping plate to slide backward, increasing the distance between the two clamping plates, press the elastic airbag to inflate the pneumatic telescopic tube, so that the limiting plate disengages from the notch, rotate handle 3 to let the limiting plate block between the discharge port and the clamping plate, put the opening of the collection bag on the outside of the discharge port, rotate handle 3 to reset, the limiting plate retracts to the notch under the action of spring 2, release handle 3, spring 1 retracts and drives the clamping plate to clamp the opening of the collection bag;

[0020] S2. Pressure roller height adjustment: Start the electric push rod through the controller, and adjust the extension length of the output end of the electric push rod according to the thickness of the suede fabric to be processed. The electric push rod pushes the concave part to move along the extension direction of the guide rod, and drives the pressure roller inside the concave part to move synchronously until the distance between the lower surface of the pressure roller and the conveying plane inside the machine box is adapted to the fabric thickness. Then turn off the electric push rod.

[0021] S3. Fabric threading: The operator holds one end of the suede fabric to be processed and inserts it into the machine box through the feed chute on the front surface of the box door. The fabric end is then passed through the front limit roller, the bottom of the pressing roller and between the napping tooth roller, and the rear limit roller in sequence, and finally out through the discharge chute on the rear surface of the machine box. During the process, the fabric surface is kept flat and without wrinkles or deviations, and the fabric is in full contact with the surface of the napping tooth roller.

[0022] S4. Equipment Start-up and Operation: Start the motor and fan in sequence. The motor drives the turntable to rotate. The turntable drives multiple fuzzing toothed rollers to move in a circular motion around the central axis of the turntable through the rotating shaft. At the same time, the gear 1 at the left end of the fuzzing toothed roller meshes with the toothed ring. The gear 1 rolls along the inner side of the toothed ring, driving the fuzzing toothed roller to rotate itself, realizing multi-roller fuzzing. After the fan starts, a negative pressure environment is formed inside the machine box. The fuzz generated by fuzzing is sucked into the collection funnel under the action of airflow and falls into the collection bag through the discharge port, completing the fuzzing operation and fuzz collection.

[0023] Beneficial effects: This device, through the coordinated operation of multiple sets of napping toothed rollers, not only makes circular motion around the central axis with the turntable driven by the motor when the turntable rotates, but also achieves its own rotation through the meshing of gears and toothed rings, forming a multi-dimensional and all-round napping action. Compared with traditional single-roller or double-roller napping machines, it greatly increases the contact area with suede fabric and the napping frequency, effectively improving napping efficiency and meeting the needs of high-capacity production.

[0024] Meanwhile, the multi-roller coordinated operation mode can make the force on the fabric surface pile more uniform, avoid excessive or insufficient local puffing, ensure the uniformity, density and length of the pile, help improve the appearance and quality of suede fabric, and meet the market's requirements for high-quality suede products.

[0025] The device features a dual-protection structure consisting of a limiting roller and an adjustable-height pressure roller. The limiting roller guides and limits the suede fabric during transport, preventing it from shifting during high-speed napping. The pressure roller's height can be precisely adjusted according to the fabric thickness via an electric push rod, consistently applying stable and appropriate pressure. Combined with the guide rod's stable guidance of the pressure roller's movement, this effectively prevents the fabric from slipping or wrinkling due to the pulling force generated by the high-speed rotation of the napping roller. This design ensures the dimensional stability of the fabric during processing and reduces the defect rate caused by fabric misalignment and wrinkles, thus lowering production losses.

[0026] The device integrates a targeted lint collection system. After the fan starts, a negative pressure environment is created inside the casing, quickly drawing lint generated during the napping process into the collection funnel. The lint then falls into the collection bag through the discharge port, preventing lint accumulation inside the equipment from affecting operational stability and reducing lint fly, thus improving the environmental quality of the production workshop. Furthermore, the collection bag is quickly clamped and fixed using a combination of clamping plates, springs, racks, and gears. Installation and replacement require no additional tools, making operation convenient and effectively preventing the collection bag from falling off under airflow. This ensures thorough lint collection, reducing the cost of subsequent fabric cleaning processes and aligning with the textile industry's trend towards high-efficiency, low-cost production.

[0036] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Example

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, a multi-roller synergistic napping machine for suede napping and its usage method are provided, including a machine housing 1, a motor 2 fixedly connected to the right side of the machine housing 1, a turntable 3 fixedly connected to the left end of the output shaft of the motor 2 inside the machine housing 1, and multiple napping toothed rollers 4 rotatably connected to the left side of the turntable 3 via a rotating shaft.

[0039] A turntable 2 5 is embedded on the left side of the housing 1. The turntable 2 5 is rotatably connected to the housing 1 via a rotating shaft. The left end of the central shaft of the napping toothed roller 4 extends through to the left side of the turntable 2 5 and is fixedly connected to a gear 1 6. A toothed ring 7 is fixedly connected to the left side of the housing 1 and outside the turntable 2 5. The outer side wall of the gear 1 6 meshes with the inner side wall of the toothed ring 7. Limiting rollers 8 are rotatably connected to the front and rear of the housing 1 via rotating shafts.

[0040] Inside the casing 1, a collecting funnel 9 is fixedly connected below the two limiting rollers 8. The bottom of the collecting funnel 9 is integrally formed with a discharge port 10.

[0041] A fan 11 is embedded and fixed on the lower right side of the chassis 1;

[0042] A door 12 is rotatably connected to the front surface of the chassis 1 via a hinge. A handle 13 is fixedly connected to the right side of the front surface of the door 12. A feed chute 14 is opened below the front surface of the door 12.

[0043] A discharge chute 15 is provided on the rear surface of the chassis 1 and behind the feed chute 14;

[0044] A second door 16 is hinged to the lower front surface of the chassis 1, and a second handle 17 is fixedly connected to the right side of the front surface of the second door 16.

[0045] Before actually starting the multi-roller synergistic napping machine for suede napping, the preliminary preparation work of the equipment must be completed first. First, the operator should open the box door 2 16 through handle 2 17, place the appropriate lint collection bag directly below the discharge port 10, and ensure that the opening of the collection bag completely covers the discharge port 10 to avoid lint leakage. Then close the box door 2 16 and check whether the protective cover 18 is tightly engaged with the outer side of the toothed ring 7 on the left side of the machine box 1.

[0046] Next, the electric push rod 19 is started by the controller. The extension length of the output end of the electric push rod 19 is adjusted according to the thickness of the suede fabric to be processed. The electric push rod 19 pushes the concave part 20 to move downward along the extension direction of the guide rod 22, which drives the pressure roller 21 inside the concave part 20 to move downward synchronously until the distance between the lower surface of the pressure roller 21 and the conveying plane inside the machine box 1 matches the fabric thickness, so as to ensure that a stable and appropriate pressure can be formed on the suede fabric during the subsequent napping process. Then the electric push rod 19 is turned off.

[0047] After completing the above preparations, the operator holds one end of the suede fabric to be processed and inserts it into the machine housing 1 through the feed chute 14 on the front surface of the door 12. The fabric end is then passed sequentially through the area above the front limiting roller 8, below the pressing roller 21, between the napping toothed roller 4, and above the rear limiting roller 8, finally exiting through the discharge chute 15 on the rear surface of the machine housing 1. During this process, it is essential to ensure that the fabric surface is flat, without wrinkles or misalignment, and to ensure full contact between the fabric and the surface of the napping toothed roller 4, laying the foundation for subsequent uniform napping.

[0048] Motor 2 and fan 11 are started in sequence, and the equipment enters the normal napping operation state. Motor 2 drives turntable 3 to rotate. Turntable 3 drives multiple napping toothed rollers 4 to rotate around the central axis of turntable 3 via a rotating shaft. At the same time, gear 6 at the left end of napping toothed roller 4 meshes with toothed ring 7 on the left side of the machine box 1. During the rotation, gear 6 rolls along the inner side of toothed ring 7, driving the napping toothed roller 4 to rotate itself, realizing the multi-roller coordinated napping process on the surface of suede fabric. After the fan 11 is started, a negative pressure environment is formed inside the machine box 1. The hair generated during the napping process is sucked into the collection funnel 9 under the action of airflow and falls into the collection bag below through the discharge port 10, completing the collection of hair.

[0049] As shown in the figure, a protective cover 18 is engaged on the left side of the chassis 1 and outside the toothed ring 7;

[0050] It provides protection for gear ring 7 and gear 6.

[0051] As shown in the figure, an electric push rod 19 is fixedly connected to the top of the chassis 1. The bottom end of the output end of the electric push rod 19 extends into the interior of the chassis 1 and is fixedly connected to a concave part 20. A pressure roller 21 is rotatably connected to the inner side of the concave part 20 via a rotating shaft. Guide rods 22 are fixedly connected to both sides of the upper surface of the concave part 20. The top end of the guide rod 22 extends into the top of the chassis 1 and is slidably connected to the chassis 1.

[0052] The electric push rod 19 can dynamically adjust the height of the pressure roller 21 according to the napping requirements of the suede fabric and the real-time processing status. When processing suede fabrics of different thicknesses, the controller sends a command to the electric push rod 19, and the output end of the electric push rod 19 extends and retracts to drive the concave part 20 to move up and down. The sliding cooperation between the guide rod 22 and the housing 1 provides stable guidance for the movement of the concave part 20, preventing the concave part 20 from deviating during the movement, ensuring that the pressure roller 21 always maintains a precise vertical alignment with the fabric, and ensuring consistent pressing effect on fabrics of different thicknesses.

[0053] As shown in the figure, a fixing block 23 is fixedly connected to the upper sides of the discharge port 10. A sliding rod 24 is fixedly connected to the front and rear surfaces of the fixing block 23. A clamping plate 25 is slidably connected to the outer side walls of the left and right opposite sliding rods 24. The opposite sides of the two clamping plates 25 are respectively attached to the front and rear surfaces of the discharge port 10. A spring 26 is fixedly connected between the fixing block 23 and the clamping plate 25 and located on the outside of the sliding rod 24.

[0054] Fixing blocks 27 are fixedly connected to the lower sides of both sides of the clamping plate 25. Racks 28 are fixedly connected to the lower and upper sides of the opposite sides of the two opposing fixing blocks 27. Gears 29 are rotatably connected to both sides of the discharge port 10 through a rotating shaft. The opposite sides of the two opposing racks 28 are meshed with the outer side of the gear 29.

[0055] A handle 30 is provided on the front surface of the clamping plate 25 located in front of the discharge port 10. An elastic airbag 31 is fixedly connected to the inner side of the handle 30. A notch 32 is provided on the rear surface of the clamping plate 25 located in front of the discharge port 10. A pneumatic telescopic tube 33 is fixedly connected to the rear surface of the handle 30 and the inner side of the notch 32. The pneumatic telescopic tube 33 and the notch 32 are rotatably connected by a rotating shaft. A limit plate 34 is fixedly connected to the rear end of the pneumatic telescopic tube 33. A plurality of springs 35 are fixedly connected between the limit plate 34 and the notch 32. An air exchange tube 36 is fixedly connected between the pneumatic telescopic tube 33 and the elastic airbag 31.

[0056] During the lint collection process, the connection stability between the collection bag and the discharge port 10 is crucial. When initially installing the collection bag, the operator can hold handle 30 and pull the clamping plate 25 located in front of the discharge port 10 forward. The clamping plate 25 slides forward along the slide bar 24, stretching the spring 26 between the fixing block 23 and the clamping plate 25. At the same time, the fixing blocks 27 on both sides of the front clamping plate 25 drive the two opposing racks 28 to move. The racks 28 mesh with the gears 29 on both sides of the discharge port 10, causing the rear clamping plate 25 to slide backward along the slide bar 24, increasing the distance between the two clamping plates 25. At this time, the opening of the collection bag is placed on the outside of the discharge port 10. The handle 30 is released, and the spring 26 contracts under its own elastic restoring force, pulling the two clamping plates 25 towards the discharge port 10 until the clamping plate 25 is tightly attached to the outside of the collection bag opening, realizing the quick clamping and fixing of the collection bag, preventing the collection bag opening from falling off or shifting under the airflow generated by the fan 11, and ensuring that all the lint falls into the collection bag.

[0057] After pulling handle 30 forward, the elastic airbag 31 can be rotated to inflate the pneumatic telescopic tube 33, causing it to extend and push the limiting plate 34 out of the recess 32. Then, by rotating handle 30, the limiting plate 34 can be rotated. After releasing handle 30, the limiting plate 34 can block the discharge port 10 and the clamping plate 25 to form an obstruction, making it easier for the cloth bag to pass through. At this time, the operator does not need to keep pulling handle 30. After the cloth bag is installed, rotate handle 30 to reset. Under the pull of spring 2 35, the limiting plate 34 retracts into the recess 32 and no longer blocks. At this time, release handle 30. Under the pull of spring 1 26, the two clamping plates 25 can stably clamp the cloth bag.

[0058] When the lint in the collection bag accumulates to a certain amount and needs to be replaced, hold the handle 30 again and pull the clamping plate 25 to increase the distance between the clamping plates 25, then remove the collection bag full of lint.

[0059] According to another aspect of the present invention, a method for using a multi-roller synergistic napping machine for suede napping is provided, comprising the following steps:

[0060] S1. Equipment Preparation: The operator opens the door 16 using handle 17, places the appropriate lint collection bag directly below the discharge port 10, ensuring the bag opening completely covers the discharge port 10, then closes the door 16 and checks if the protective cover 18 is tightly engaged with the outer side of the toothed ring 7 on the left side of the casing 1. Simultaneously, the operator grasps handle 30 on the clamping plate 25 in front of the discharge port 10 and pulls the clamping plate 25 forward. The clamping plate 25 slides along the slide rod 24 and stretches the spring 26. The front clamping plate 25 moves the rack 28 via the fixing block 27. The rack 28 meshes with the gear 29, causing the rear clamping plate 25 to slide backward, increasing the distance between the two clamping plates 25. The operator presses the elastic airbag 31 to inflate the pneumatic telescopic tube 33, causing the limiting plate 34 to disengage from the notch 32. S1. Turn handle 30 to block the limit plate 34 between the discharge port 10 and the clamping plate 25. Place the collection bag opening on the outside of the discharge port 10. Turn handle 30 to reset. The limit plate 34 retracts to the notch 32 under the action of spring 2 35. Release handle 30. Spring 1 26 retracts and drives the clamping plate 25 to clamp the collection bag opening. S2. Adjust the height of the pressure roller: Start the electric push rod 19 through the controller. Adjust the extension length of the output end of the electric push rod 19 according to the thickness of the suede fabric to be processed. The electric push rod 19 pushes the concave part 20 to move along the extension direction of the guide rod 22, and drives the pressure roller 21 inside the concave part 20 to move synchronously until the distance between the lower surface of the pressure roller 21 and the conveying plane inside the machine box 1 matches the fabric thickness. Then turn off the electric push rod 19.

[0061] S3. Fabric threading: The operator holds one end of the suede fabric to be processed and inserts it into the machine box 1 through the feed groove 14 on the front surface of the box door 12. The fabric end is then passed through the front limit roller 8, the lower part of the pressing roller 21, between the napping tooth roller 4, and the rear limit roller 8 in sequence, and finally out through the discharge groove 15 on the rear surface of the machine box 1. During the process, the fabric surface is kept flat and without wrinkles or deviations, and the fabric is in full contact with the surface of the napping tooth roller 4.

[0062] S4. Equipment Start-up and Operation: Start motor 2 and fan 11 in sequence. Motor 2 drives turntable 3 to rotate. Turntable 3 drives multiple fuzzing toothed rollers 4 to rotate around the central axis of turntable 3 via a rotating shaft. At the same time, gear 6 at the left end of fuzzing toothed roller 4 meshes with gear ring 7. Gear 6 rolls along the inner side of gear ring 7, driving fuzzing toothed roller 4 to rotate itself, realizing multi-roller fuzzing. After the fan 11 is started, a negative pressure environment is formed inside the casing 1. The fuzz generated by fuzzing is sucked into the collection funnel 9 under the action of airflow and falls into the collection bag through the discharge port 10, completing the fuzzing operation and fuzz collection.

[0063] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.

10. A method of using a multi-roller synergistic napping machine for suede napping, comprising the multi-roller synergistic napping machine for suede napping as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Equipment preparation: The operator opens the second door (16) through handle two (17), places the appropriate lint collection bag directly below the discharge port (10), and ensures that the opening of the collection bag completely covers the discharge port (10). Then, close the second door (16) and check whether the protective cover (18) is tightly engaged with the outer side of the toothed ring (7) on the left side of the machine box (1). At the same time, hold the third handle (30) on the clamping plate (25) in front of the discharge port (10), and pull the clamping plate (25) forward. The clamping plate (25) slides along the slide rod (24) and stretches the first spring (26). The front clamping plate (25) moves the rack (28) through the fixing block two (27). When the rack (28) and gear two (29) mesh, the rear clamping plate (25) slides backward, increasing the distance between the two clamping plates (25). Press the elastic airbag (31) to inflate the pneumatic telescopic tube (33), so that the limiting plate (34) disengages from the notch (32). Turn the handle three (30) to make the limiting plate (34) block between the discharge port (10) and the clamping plate (25), put the collection bag opening on the outside of the discharge port (10), turn the handle three (30) to reset, and the limiting plate (34) retracts to the notch (32) under the action of spring two (35). Release the handle three (30), and spring one (26) retracts to drive the clamping plate (25) to clamp the collection bag opening. S2, Adjustment of the height of the pressing roller: Start the electric push rod (19) through the controller, adjust the extension length of the output end of the electric push rod (19) according to the thickness of the suede fabric to be processed, the electric push rod (19) pushes the concave part (20) to move along the extension direction of the guide rod (22), and drives the pressing roller (21) inside the concave part (20) to move synchronously until the distance between the lower surface of the pressing roller (21) and the conveying plane inside the machine box (1) is adapted to the thickness of the fabric, and then turn off the electric push rod (19); S3. Fabric insertion: The operator holds one end of the suede fabric to be processed and inserts it into the machine box (1) through the feed groove (14) on the front surface of the box door (12). The fabric end is then passed through the front limiting roller (8), the pressing roller (21) below and between the napping tooth roller (4), and the rear limiting roller (8) in sequence, and finally out through the discharge groove (15) on the rear surface of the machine box (1). During the process, the fabric surface is kept flat and without wrinkles or deviations, and the fabric is in full contact with the surface of the napping tooth roller (4). S4. Equipment Start-up and Operation: Start the motor (2) and the fan (11) in sequence. The motor (2) drives the turntable (3) to rotate. The turntable (3) drives multiple fuzzing toothed rollers (4) to make circular motion around the central axis of the turntable (3) through the rotating shaft. At the same time, the gear (6) on the left end of the fuzzing toothed roller (4) meshes with the toothed ring (7). The gear (6) rolls along the inner side of the toothed ring (7) to drive the fuzzing toothed roller (4) to rotate itself, so as to realize multi-roller fuzzing. After the fan (11) is started, a negative pressure environment is formed inside the machine box (1). The fuzz generated by fuzzing is sucked into the collection funnel (9) under the action of airflow and falls into the collection bag through the discharge port (10), thus completing the fuzzing operation and fuzz collection.
