Description

Technical Field

[0001] This utility model relates to the field of processing devices, and in particular to a device for smoothing the surface of anti-pilling nylon staple fibers. Background Technology

[0002] Nylon staple fiber is widely used in the textile industry due to its high strength and abrasion resistance. However, ordinary nylon staple fiber has microscopic protrusions and fuzz on its surface. During wear and use, the fibers are prone to entanglement and friction, resulting in severe pilling. This greatly affects the appearance and quality of the fabric, shortens its service life, and limits the further expansion of nylon staple fiber in the high-end textile market. To solve this problem, a special surface treatment device has been designed.

[0003] In existing technologies, during high-speed friction processing, the intense relative motion between the device and the wool felt surface directly affects the fiber layer. When the frictional force exceeds the fiber bonding strength, microscopic peeling occurs on the fiber surface. These detached fiber fragments are lifted by centrifugal force, forming fiber dust suspended in the processing area. As the processing time increases, the detached fibers gradually deposit on the wool felt surface. On the one hand, fiber accumulation alters the original morphology of the material surface, forming an uneven soft layer at the friction interface, resulting in a reduced actual contact area. On the other hand, the lifted fiber dust penetrates the transmission components and guide rail system of the device, forming fiber clumps in the gaps between moving parts. This directly leads to a stepwise decrease in friction efficiency. To address the efficiency degradation problem, current production processes typically involve shutdown for cleaning, which results in the entire production line stagnating during downtime, causing a direct loss of unit capacity. Therefore, it is necessary to improve the anti-pilling nylon staple fiber surface smoothing device to solve the above problems. Utility Model Content

[0004] To overcome the problem that fiber shedding during high-speed friction forms micro-dust, which deposits and alters the morphology of wool felt, reduces the contact area and affects the cleaning effect, and seriously affects work efficiency when cleaning is done while the machine is stopped.

[0005] The technical solution of this utility model is as follows: an anti-pilling nylon staple fiber surface smoothing treatment device, including a device body, a support base fixedly connected to the device body, a first fixed seat fixedly connected to the device body, a first threaded rod rotatably connected to the first fixed seat, a first knob fixedly connected to one end of the first threaded rod, a connecting seat threadedly connected to the first threaded rod, a first push rod body fixedly connected to the connecting seat, a fixed plate fixedly connected to one end of the first push rod body, a sliding rack fixedly connected to the fixed plate, a first gear meshing with the sliding rack, a rotating bracket fixedly connected to the first gear, a wool felt body disposed on the rotating bracket, an ink coating roller body disposed on the device body, a drive assembly disposed on the connecting seat, and a dust collection assembly disposed on the device body. The connecting seat is slidably connected to the first fixed seat, the sliding rack is slidably connected to the connecting seat, and the rotating bracket is rotatably connected to the connecting seat. Rotating the first knob drives the first threaded rod to rotate. When the first threaded rod rotates, it adjusts the movement of the connecting seat. The first push rod body works to push the fixed plate and the sliding rack to move. When the sliding rack moves, it adjusts the rotation of the rotating bracket and the wool felt body by cooperating with the first gear.

[0006] Preferably, the first fixed seat has a limiting groove at the relative position of the first threaded rod, and the first threaded rod is rotatably connected to the groove.

[0007] Preferably, the connecting seat has a limiting groove at the relative position of the rotating bracket, and the rotating bracket is rotatably connected to the groove.

[0008] Preferably, the connecting seat has a limiting groove at the relative position of the sliding rack, and the sliding rack is slidably connected to the groove.

[0009] Preferably, the drive assembly includes a first motor fixedly connected to the connecting seat, a rotating shaft fixedly connected to the output end of the first motor, a second gear fixedly connected to one end of the rotating shaft, a third gear meshing with the second gear, and the third gear fixedly connected to the felt body. The first motor is used to drive the rotating shaft to rotate, and when the rotating shaft rotates, it drives the third gear to rotate through the second gear.

[0010] Preferably, the rotating bracket has a through groove inside, and the rotating shaft passes through the through groove and is fixedly connected between the second gear and the first motor.

[0011] Preferably, the dust collection assembly includes a dust collection port fixedly connected to the connecting seat, a first connecting pipe fixedly connected to the dust collection port, a fixed outer casing fixedly connected to the main body of the device, a second connecting pipe fixedly connected between the fixed outer casing and the first connecting pipe, a sliding plate slidably connected to the fixed outer casing, a pre-filter plate disposed on the sliding plate, a dust filter plate disposed on the sliding plate, an activated carbon filter plate disposed on the sliding plate, and a centrifugal fan body fixedly connected to the fixed outer casing.

[0012] Preferably, three sliding plates are provided, all three sliding plates are slidably connected to the fixed outer casing, and the pre-filter plate, dust filter plate and activated carbon filter plate are respectively set on the three pre-filter plates.

[0013] The beneficial effects of this utility model are: 1. When the processing effect of one set of wool felt bodies decreases during use, the first push rod body drives the rotating bracket and wool felt body to flip over, and another set of wool felt bodies takes over the first set of wool felt bodies to continue the processing work. The other set is simultaneously cleaned by the dust collection component. The wool felt can be cleaned without stopping the machine, avoiding production line stagnation caused by cleaning a single set, greatly reducing downtime loss, significantly increasing the processing volume per unit time, ensuring the continuity and stability of the production process, and improving unit productivity.

[0014] 2. In actual processing, by rotating the first knob to adjust the height of the connecting seat, the wool felt body and other components can be raised and lowered synchronously, flexibly adjusting the relative distance between it and the anti-pilling nylon short fibers to be treated. This allows it to adapt to fiber materials of different thicknesses and specifications, ensuring that the wool felt contacts the fiber surface with appropriate pressure, guaranteeing consistent treatment results, and expanding the applicability of the equipment.

[0015] 3. Through layered filtration, a step-by-step purification process from coarse to fine is achieved, significantly improving the filtration efficiency for micro-dust in the processing area. This ensures higher air cleanliness and minimizes the impact on the environment and surrounding workers. The three filter layers are set on three sliding plates and can be individually disassembled and replaced. When a filter layer reaches saturation, there is no need to replace the entire filter structure. This makes cleaning and maintenance more convenient, shortens maintenance time, reduces downtime caused by maintenance, and indirectly improves the continuous operation capability of the equipment.

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please see Figure 1 - Figure 6This utility model provides an embodiment of an anti-pilling nylon staple fiber surface smoothing treatment device, including a device body 1, and further including a support base 4 fixedly connected to the device body 1, a first fixed seat 21 fixedly connected to the device body 1, a first threaded rod 22 rotatably connected to the first fixed seat 21, a first knob 23 fixedly connected to one end of the first threaded rod 22, a connecting seat 24 threadedly connected to the first threaded rod 22, a first push rod body 25 fixedly connected to the connecting seat 24, a fixed plate 26 fixedly connected to one end of the first push rod body 25, a sliding rack 27 fixedly connected to the fixed plate 26, a first gear 28 meshing with the sliding rack 27, a rotating bracket 29 fixedly connected to the first gear 28, and a mounting bracket 29 disposed on the first gear 28. The rotating bracket 29 comprises a felt body 210, an ink application roller body 215, a drive assembly, and a dust collection assembly. The drive assembly is slidably connected to the first fixed seat 21, and the sliding rack 27 is slidably connected to the drive assembly 24. The rotating bracket 29 is rotatably connected to the drive assembly 24. Rotating the first knob 23 drives the first threaded rod 22 to rotate. When the first threaded rod 22 rotates, it adjusts the movement of the drive assembly 24. The first push rod body 25 pushes the fixed plate 26 and the sliding rack 27 to move. When the sliding rack 27 moves, it adjusts the rotation of the rotating bracket 29 and the felt body 210 by cooperating with the first gear 28. When the device is running, the first knob 23 is rotated first. Button 23 drives the first threaded rod 22 to rotate within the groove of the first fixed seat 21. Since the first threaded rod 22 is threadedly connected to the connecting seat 24, and the connecting seat 24 is slidably connected to the first fixed seat 21, the rotation of the first threaded rod 22 will drive the connecting seat 24 to move along the length direction of the first fixed seat 21, thereby adjusting the overall position of the connecting seat 24 and its connected components to adapt to different processing requirements. During the processing, the drive assembly starts and drives the wool felt body 210 to rotate through the transmission, polishing the surface of the nylon short fiber. After the fiber thread passes through the ink coating roller body 215, due to the affinity between the thread surface and the silicone oil, the oil film on the roller surface will be evenly transferred to the thread surface, forming a layer of continuous coating. The coating process continues to reduce the surface friction coefficient of the yarn, improve anti-pilling properties, and ensure coating stability. When the wool felt body 210 has been processed for a long time and its surface is covered with a lot of fiber particles, affecting the processing effect, the first push rod body 25 is activated, pushing the fixed plate 26 to move. The fixed plate 26 drives the sliding rack 27 to slide in the groove of the connecting seat 24. The sliding rack 27 meshes with the first gear 28, driving the first gear 28 to rotate. This causes the rotating bracket 29 to flip in the rotating groove of the connecting seat 24. At this time, another set of wool felt bodies 210 set on the rotating bracket 29 flips to the working position, replacing the previous set of wool felt bodies 210 with a lot of fiber particles attached, ready to continue the surface smoothing treatment of nylon staple fibers.After alternation, the vacuuming components work synchronously to vacuum up dust, debris, and other impurities on the first set of felt bodies 210 after replacement.

[0020] Please see Figure 1 - Figure 5In this embodiment, the first fixed seat 21 has a limiting groove at the relative position of the first threaded rod 22, and the first threaded rod 22 is rotatably connected to the groove. In this structure, the groove limits the first threaded rod 22, preventing it from shifting during rotation. Through the rotatable connection, the first threaded rod 22 can rotate stably around its own axis, providing a reliable rotational basis for adjusting the relative position between the first fixed seat 21 and the first threaded rod 22, ensuring the stability of the adjustment process. The connecting seat 24 has a limiting groove at the relative position of the rotating bracket 29, and the rotating bracket 29 is rotatably connected to the groove. The rotating groove constrains the rotation trajectory of the rotating bracket 29, preventing axial movement or deviation from the preset rotation center during rotation. The rotating connection allows the rotating bracket 29 to rotate flexibly within the groove's defined range, enabling multi-angle relative position adjustments between the connecting seat 24 and the rotating bracket 29, thus improving the device's adaptability under different working conditions. The connecting seat 24 has a limiting groove at the relative position of the sliding rack 27. The sliding rack 27 is slidably connected to the groove, which provides guidance and limits its movement trajectory, ensuring it can only move along the extension direction of the groove. The sliding mechanism allows for linear sliding, while the groove also supports the sliding rack 27, reducing wobbling during sliding and ensuring more stable and reliable meshing transmission between the sliding rack 27 and other components. The drive assembly includes a first motor 211 fixedly connected to the connecting seat 24, a rotating shaft 212 fixedly connected to the output end of the first motor 211, a second gear 213 fixedly connected to one end of the rotating shaft 212, and a third gear 214 meshing with the second gear 213. The third gear 214 is fixedly connected to the felt body 210. The first motor 211 drives the rotating shaft 212 to rotate, and the rotating shaft 212 rotates through the second gear 213. The first motor 211 provides power output to the second gear 213 via the rotating shaft 212. The gears then mesh to drive the third gear 214, which in turn drives the wool felt body 210 to rotate, thus enabling the wool felt body 210 to rotate actively. This provides power for the device's grinding and cleaning operations. The gear transmission features high efficiency and precise transmission ratio, ensuring stable and controllable rotation speed of the wool felt body 210. The rotating bracket 29 has a through slot inside, through which the rotating shaft 212 passes and is fixedly connected between the second gear 213 and the first motor 211. The through slot provides a passage for the rotating shaft 212 to pass through the rotating bracket 29, allowing it to transmit power from one side of the rotating bracket 29 to the second gear 213 on the other side without interfering with the structure of the rotating bracket 29. This avoids motion interference between the rotating shaft 212 and the rotating bracket 29, ensuring power transmission.

[0021] Please see Figure 2 , Figure 6 In this embodiment, the dust collection assembly includes a dust collection port 31 fixedly connected to the connecting seat 24, a first connecting pipe 32 fixedly connected to the dust collection port 31, a fixed outer casing 33 fixedly connected to the main body 1, a second connecting pipe 34 fixedly connected between the fixed outer casing 33 and the first connecting pipe 32, a sliding plate 35 slidably connected to the fixed outer casing 33, a pre-filter plate 36 disposed on the sliding plate 35, a dust filter plate 37 disposed on the sliding plate 35, an activated carbon filter plate 38 disposed on the sliding plate 35, and a centrifugal fan body 39 fixedly connected to the fixed outer casing 33. The dust collection port 31 is used to collect dust, debris, and other impurities generated during operation. The impurities are transported to the fixed outer casing 33 through the first connecting pipe 32 and the second connecting pipe 34. The centrifugal fan body 39 provides negative pressure suction, allowing the impurities to enter the fixed outer casing 33. The pre-filter plate 36 can first filter larger particles. The system performs preliminary filtration of particulate impurities, with dust filter plate 37 further filtering fine dust, and activated carbon filter plate 38 adsorbing odors and harmful gases in the air. The sliding connection between sliding plate 35 and fixed outer casing 33 facilitates the disassembly, cleaning, and replacement of the filter plates, ensuring the long-term effective operation of the dust collection assembly. There are three sliding plates 35, all slidably connected to the fixed outer casing 33. The pre-filter plate 36, dust filter plate 37, and activated carbon filter plate 38 are respectively installed on the three pre-filter plates 36. The independent arrangement of the three sliding plates 35 allows the pre-filter plate 36, dust filter plate 37, and activated carbon filter plate 38 to be installed and disassembled separately. When one filter plate needs maintenance or replacement, it is not necessary to disassemble the other filter plates, simplifying the maintenance process and avoiding mutual interference between different filter plates, ensuring that each filter plate can independently and efficiently perform its filtration function.

[0022] When the device is in operation, firstly, by rotating the first knob 23, the first threaded rod 22 is driven to rotate within the groove of the first fixed seat 21. Since the first threaded rod 22 is threadedly connected to the connecting seat 24, and the connecting seat 24 is slidably connected to the first fixed seat 21, the rotation of the first threaded rod 22 will drive the connecting seat 24 to move along the length direction of the first fixed seat 21, thereby adjusting the overall position of the connecting seat 24 and its connected components to adapt to different processing requirements. During the processing, the drive assembly is activated, and the first motor 211 fixed on the connecting seat 24 works to drive the rotating shaft 212 to rotate. The rotating shaft 212 passes through the through groove of the rotating bracket 29, and the second gear 213 at one end of it rotates with the rotating shaft 212. As the second gear 213 meshes with the third gear 214, it drives the third gear 214 to rotate. Since the third gear 214 is fixedly connected to the wool felt body 210, the wool felt body 210 rotates accordingly, polishing the surface of the nylon short fibers. After the fiber yarn passes through the ink coating roller body 215, the oil film on the roller surface is evenly transferred to the yarn surface due to the affinity between the yarn surface and the silicone oil, forming a continuous coating layer. This reduces the surface friction coefficient of the yarn, improves anti-pilling properties, and ensures coating stability. When the wool felt body 210 has been working for a long time and its surface has a lot of fiber particles attached, affecting the treatment effect, the first push rod body 25 starts working. The fixed plate 26 is pushed to move, causing the sliding rack 27 to slide within the groove of the connecting seat 24. The sliding rack 27 meshes with the first gear 28, driving the first gear 28 to rotate. This causes the rotating bracket 29 to flip within the rotating groove of the connecting seat 24. At this time, another set of wool felt bodies 210 mounted on the rotating bracket 29 flips to the working position, replacing the previous set of wool felt bodies 210 with more fiber particles attached, ready to continue the surface smoothing treatment of nylon short fibers. After the alternation, the dust collection components work synchronously, with the centrifugal fan body 39 providing negative pressure suction to collect dust, debris, and other impurities from the replaced first set of wool felt bodies 210. The dust passes through the connecting seat 24. The air enters through the suction port 31 on the 4th section and is transported to the fixed outer casing 33 via the first connecting pipe 32 and the second connecting pipe 34. Impurities are filtered and purified sequentially through the pre-filter plate 36, the dust filter plate 37, and the activated carbon filter plate 38 within the fixed outer casing 33. The pre-filter plate 36 filters larger particles, the dust filter plate 37 filters fine dust, and the activated carbon filter plate 38 adsorbs odors and harmful gases. The purified air is then discharged, while the filtered impurities remain on the filter plates. Three sliding plates 35 are installed on the pre-filter plate 36, the dust filter plate 37, and the activated carbon filter plate 38, respectively, and are slidably connected to the fixed outer casing 33, facilitating subsequent disassembly, cleaning, or replacement of the filter plates to ensure continuous suction performance.

[0023] Through the above steps, when the processing effect of one set of wool felt bodies 210 decreases during use, the first push rod body 25 drives the rotating bracket 29 to flip the wool felt body 210, and another set of wool felt bodies 210 replaces the first set of wool felt bodies 210 to continue the processing work. The other set is simultaneously dusted by the dust collection component, which solves the problem that fiber shedding during high-speed friction forms micro-dust, which deposits and changes the morphology of wool felt, reduces the contact area and affects the cleaning effect, and seriously affects work efficiency when the machine is stopped for cleaning.
