Description

Technical Field

[0001] This utility model relates to the field of cashmere combing machines, specifically a cashmere combing device with a self-cleaning function. Background Technology

[0002] Cashmere carding machines achieve efficient fiber processing through the synergistic action of rollers, cylinder rollers, doffer rollers, and needle rollers. Rollers control fiber feeding, while needle rollers rotate at high speed to break down fiber bundles and remove impurities, forming a stripping zone with the cylinder rollers for initial carding. The cylinder rollers then finely card, straighten, and mix the fibers, forming a cohesion zone with the doffer rollers. The doffer rollers cohede the fibers into a uniform layer for output. Through speed ratios, needle tooth configurations, and relative motion, each roller achieves gradual fiber carding, impurity removal, and uniform web formation, ensuring carding quality and efficiency.

[0003] In existing cashmere carding machines, un-carded cashmere enters the machine and passes through rollers, cylinder rollers, doffer rollers, and needle rollers. Due to the different speed ratios of these rollers, the cashmere is carded. However, a problem exists in actual use: specifically, the rollers at the feeding end are only responsible for feeding and have difficulty opening up relatively concentrated cashmere. This results in the need for repeated carding of concentrated cashmere to achieve an effective carding effect, which undoubtedly reduces the carding machine's adaptability to relatively concentrated cashmere and reduces the carding efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a cashmere combing machine combing device with self-cleaning function, so as to solve the technical problem of insufficient opening of the rollers in the existing cashmere combing machine leading to reduced combing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cashmere combing machine with self-cleaning function, comprising a main body and a combing assembly, wherein the combing assembly includes a cylinder roller, a roller roller, and a doffer roller, and an opening mechanism is provided above the roller roller for opening up the accumulated cashmere, wherein the opening mechanism includes an opening roller, and a plurality of needle teeth are uniformly fixed on the surface of the opening roller, and a longitudinal adjustment mechanism is provided between the two ends of the opening roller and the main body of the device for adjusting the distance between the roller roller and the opening roller.

[0006] By adopting the above technical solution, the uniform needle teeth on the surface of the spreading roller pre-open the concentrated cashmere, effectively breaking the entanglement structure between fibers and reducing the resistance of subsequent combing; at the same time, the longitudinal adjustment mechanism dynamically adjusts the distance between the roller and the spreading roller, so that the equipment can adapt to cashmere raw materials with different impurity content and fiber length and thickness.

[0007] Furthermore, the longitudinal adjustment mechanism includes a mounting frame, on the inner side of which a slider is longitudinally engaged and slidable, and both ends of the opening roller are rotatably connected to the slider via bearing seats.

[0008] By adopting the above technical solution, the linear motion stability of the opening roller during the adjustment process is ensured, and the skew friction between the needle teeth and the roller surface is avoided.

[0009] Furthermore, an adjusting screw is threaded onto the mounting frame, and the end of the adjusting screw is rotatably connected to the slider.

[0010] By adopting the above technical solution, the distance between the roller and the opening roller can be adjusted, and the operator can quickly adjust the parameters while the equipment is stopped.

[0011] Furthermore, a self-cleaning mechanism is installed below the doffer roller. The self-cleaning mechanism includes several flaps, and gaps are formed between adjacent flaps to allow for the discharge of debris.

[0012] By adopting the above technical solution, the self-cleaning mechanism uses a flap structure, which utilizes the gap between the flaps to automatically discharge impurities, thus avoiding the problem of easy clogging.

[0013] Furthermore, a horizontal receiving plate is installed on the lower inner side of the main body of the device to receive debris falling from the self-cleaning mechanism.

[0014] By adopting the above technical solution, the receiving plate ensures that the impurities discharged by the self-cleaning mechanism can be collected in a targeted manner, avoiding them from scattering into the combing area and causing secondary pollution.

[0015] Furthermore, several needle rollers are provided on the outer side of the cylinder roller, and a receiving frame is installed on one side of the main body of the device. A conveyor belt is installed inside the receiving frame to discharge the combed cashmere.

[0016] By adopting the above technical solution, multiple sets of needle rollers form a multi-stage combing system, which achieves progressive opening and combing of fibers through different combinations of needle tooth densities, thereby improving the combing precision.

[0017] Furthermore, a guide roller is installed on the side of the doffer roller near the receiving frame, a pressure roller is rotatably installed above the side of the receiving frame near the guide roller, and an unwinding roller is installed on the other side of the main body of the device.

[0018] By adopting the above technical solution, the fiber layer maintains constant tension during the export process through the clamping action of the export roller and the pressure roller, thus preventing loosening or breakage.

[0019] In summary, the present invention has the following main advantages:

[0020] This invention utilizes an opening mechanism. After cashmere is fed into the rollers via the unwinding roller, it first contacts the opening mechanism. The evenly distributed needle teeth on the surface of the opening roller pre-open the concentrated cashmere, directly breaking the entanglement knots between fibers and significantly reducing the combing resistance of the subsequent combing components.

[0021] This invention uses a longitudinal adjustment mechanism to adjust the distance between the roller and the opening roller, so that the pre-opening strength is adapted to raw materials with different fiber lengths and impurity contents, avoiding fiber breakage caused by excessive opening and improving the environmental applicability of the opening mechanism.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example

[0028] A cashmere combing machine with self-cleaning function, such as Figure 1-4As shown, the device includes a main body 1 and a combing assembly 3. The combing assembly 3 includes a cylinder roller 301, a roller roller 302, and a doffer roller 303. Above the roller roller 302, there is a spreading mechanism 5 for loosening the piled cashmere. The spreading mechanism 5 includes a spreading roller 501. The surface of the spreading roller 501 is uniformly fixed with a number of needle teeth. The two ends of the spreading roller 501 are provided with a longitudinal adjustment mechanism between them and the main body 1 to adjust the distance between the roller roller 302 and the spreading roller 501. The uniform needle teeth on the surface of the spreading roller 501 pre-loosen the concentrated cashmere, effectively breaking the entanglement structure between fibers and reducing the resistance of subsequent combing. At the same time, the distance between the roller roller and the spreading roller is dynamically adjusted by the longitudinal adjustment mechanism, so that the equipment can adapt to cashmere raw materials with different impurity contents, fiber lengths and thicknesses, significantly reducing the number of repeated fiber combing, improving combing efficiency, and avoiding fiber breakage caused by over-combing, thus ensuring the length and quality of cashmere.

[0029] See Figure 1 , Figure 2 The longitudinal adjustment mechanism includes a mounting frame 504, with a slider 502 longitudinally engaged and sliding inside the mounting frame 504. The two ends of the spreading roller 501 are rotatably connected to the slider 502 via bearing seats 503, ensuring the linear motion stability of the spreading roller 501 during the adjustment process and preventing skewed friction between the needle teeth and the roller surface. At the same time, the rotatable connection between the slider 502 and the bearing seat 503 allows the spreading roller 501 to rotate flexibly even when subjected to fiber resistance, reducing mechanical wear. This structure makes adjustment easier to maintain, improves adjustment accuracy, and extends the service life of the equipment.

[0030] See Figure 1 , Figure 2 An adjusting screw 505 is threaded onto the mounting frame 504. The end of the adjusting screw 505 is rotatably connected to the slider 502, which realizes the adjustment of the distance between the roller roller 302 and the opening roller 501. The operator can quickly adjust the parameters while the equipment is stopped. At the same time, the self-locking characteristic of the thread ensures the stability of the distance after adjustment, avoids parameter drift caused by vibration, improves the adaptability of the equipment to different batches of cashmere, and significantly shortens the process debugging cycle. Example

[0031] See Figure 3 , Figure 4 Below the doffer roller 303, a self-cleaning mechanism 4 is installed. The self-cleaning mechanism 4 includes several flaps 401, and gaps 402 are formed between adjacent flaps 401 for the discharge of impurities. The self-cleaning mechanism 4 adopts the flap 401 structure and uses the gaps 402 between the flaps 401 to realize the automatic discharge of impurities, avoiding the problem of easy clogging. At the same time, the synergistic effect between the surface of the flaps 401 and the doffer needle teeth can further peel off impurities attached to the fibers, thereby improving the impurity removal efficiency, reducing the frequency of manual cleaning, and significantly improving the continuous operation capability of the equipment.

[0032] See Figure 3 , Figure 4 A horizontal receiving plate 2 is installed on the lower inner side of the main body 1 of the device to receive debris falling from the self-cleaning mechanism 4. The receiving plate 2 ensures that the impurities discharged from the self-cleaning mechanism 4 can be collected in a directional manner to avoid scattering to the combing area and causing secondary pollution. At the same time, the surface of the receiving plate 2 adopts an inclined flow guiding structure, which facilitates the centralized cleaning of impurities, improves the cleanliness of the workshop environment, reduces the impurity content of fibers, and effectively ensures the purity of the finished cashmere.

[0033] See Figure 1 , Figure 2 Several needle rollers 304 are arranged on the outer side of the cylinder roller 301. A receiving frame 306 is installed on one side of the main body 1. A conveyor belt is installed inside the receiving frame 306 to discharge the combed cashmere. Multiple sets of needle rollers 304 form a multi-stage combing system. By combining different needle tooth densities, the fibers are gradually opened and combed, improving the fineness of combing. At the same time, the conveyor belt built into the receiving frame 306 works in synergy with the needle rollers 304 to enable the combed cashmere to be discharged automatically and continuously, thereby improving the uniformity of cashmere combing, increasing the output per unit time, and achieving efficient and continuous production.

[0034] See Figure 1 , Figure 2 A doffer roller 303 is installed on the side of the receiving frame 306 near the doffer roller 303, and a pressure roller 308 is rotatably installed above the side of the receiving frame 306 near the doffer roller 305. An unwinding roller 307 is installed on the other side of the main body 1. Through the clamping action of the doffer roller 305 and the pressure roller 308, the fiber layer maintains constant tension during the export process, avoiding loosening or breakage. At the same time, the synchronous operation of the unwinding roller 307 realizes the continuous winding output of the fiber layer. The integration of this system reduces the cashmere export damage rate, improves the uniformity of the finished product roll, and significantly improves the processing efficiency of subsequent processes.

[0035] The implementation principle of this embodiment is as follows: After the cashmere is fed into the main body 1 of the device by the unwinding roller 307 through the roller 302, it first contacts the newly added opening mechanism 5. The needles evenly distributed on the surface of the opening roller 501 pre-open the concentrated cashmere. The distance between its two ends and the roller 302 is dynamically adjusted by the longitudinal adjustment mechanism to adapt to different fiber thicknesses and improve the opening efficiency. The pre-treated cashmere enters the combing assembly 3. The cylinder roller 301 and the outer needle roller 304 achieve fine combing through the speed ratio difference. The doffer roller 303 condenses the combed fibers into a uniform layer. During this process, the self-cleaning mechanism 4 below the doffer roller 303 automatically removes impurities through the gap 402 of the flip plate 401 to avoid excessive accumulation of impurities. The impurities are collected by the horizontal receiving plate 2 to avoid fiber damage. Finally, the doffer roller 303, through the cooperation of the guide roller 305 and the pressure roller 308, transports the fiber layer to the conveyor belt of the receiving frame 306.

[0036] In this embodiment, the spreading roller 501 is powered by an external motor to achieve effective power distribution and improve the opening effect on the cashmere. The spreading roller 501, also known as a fabric spreading roller or wrinkle-removing roller, has mounting plates on it that move laterally as it rotates, thus effectively opening the cashmere. Its structural principle is well-known in the mechanical field, therefore the inventor will not elaborate further here.
