Description

Technical Field

[0001] This utility model belongs to the field of cashmere processing technology, and in particular relates to a cooling device for the feeding section of a cashmere combing machine. Background Technology

[0002] Cashmere combing is a crucial step in cashmere processing, aimed at separating impurities such as coarse hair and dander from cashmere to obtain pure cashmere fibers. During operation, the high-speed rotation of the combing rollers and the intense friction with the fibers generate a large amount of heat, causing a significant increase in the internal temperature of the equipment. Furthermore, the combing process produces a large amount of unwanted hair that needs to be removed.

[0003] High temperatures can have many adverse effects on the cashmere combing process: First, excessively high temperatures can damage cashmere fibers, making them brittle and losing elasticity, thus affecting the quality and value of the finished cashmere product. Second, in a high-temperature environment, the electrostatic effect on the surface of cashmere fibers will be enhanced, making the fibers more likely to entangle and stick to the equipment, which not only affects the combing efficiency but also increases the difficulty of cleaning and maintenance.

[0004] In the prior art, there are several publicly available technical solutions attempting to cool cashmere carding machines. For example, document CN222540944U discloses a cashmere carding machine feeding device, which uses a cooling treatment component inside the outer shell, including a telescopic cylinder, an inner cover, a cooling pipe, and dispersing air holes. This solution actively generates cold air through the cooling pipe and blows it downwards onto the cashmere to achieve cooling. Those skilled in the art believe that using a cooling pipe as a cold source requires a large amount of electrical energy, and the cooling system itself has a complex structure, increasing manufacturing costs and failure rates. Furthermore, this technical solution only focuses on cooling and does not integrate dust removal functionality; dust and lint accumulate inside the equipment, not only affecting the working environment but also potentially being blown back into the cashmere by the high-temperature airflow, causing secondary pollution. The entire top-down blowing method means the airflow mainly acts on the surface of the cashmere, making it difficult to penetrate the fiber layer for uniform and thorough cooling. Simultaneously, its airflow path is open, allowing cold air to easily dissipate, resulting in low energy utilization. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cooling device for the feeding section of a cashmere combing machine. This device can not only effectively reduce the temperature of cashmere fibers during the feeding and combing process, but also remove the generated dust simultaneously. It also has the advantages of low energy consumption, reasonable structure, and reliable operation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a cooling device for the feeding section of a cashmere combing machine, comprising a support base and an outer shell disposed on one side of the support base. On the other side of the support base is a double-outlet mechanism for cashmere fibers. Inside the outer casing behind the double-outlet mechanism are a collecting roller mechanism and a combing mechanism, which are then connected to the main body of the cashmere combing machine. A wind-cooled dust collection mechanism is located below the support base between the collecting roller mechanism and the carding mechanism.

The rear guide wheel is sleeved on the second rotating shaft, the second rotating shaft is fixed on the second bracket, and the second bracket and the guide are integrally formed; a pair of second limiting rods are also provided at the rear of the guide to restrict the movement of cashmere fibers.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-5 A cooling device for the feeding section of a cashmere carding machine includes a support base 1 and an outer casing 2 disposed on one side of the support base 1. A dual-outlet cashmere fiber mechanism 3 is disposed on the other side of the support base 1. A collecting roller mechanism 4 and a carding mechanism 5 are sequentially disposed within the outer casing 2 behind the dual-outlet mechanism 3, and finally connected to the main body of the cashmere carding machine. A wind-cooled dust collection mechanism 6 is disposed between the collecting roller mechanism 4 and the carding mechanism 5, located below the support base 1. The wind-cooled dust collection mechanism 6 cools and cleans the cashmere fibers passing through the outer casing 2. The dual-outlet mechanism 3 refers to the mechanism used to simultaneously place two cashmere feed rollers to achieve dual-path feeding.

[0019] In this embodiment, the dual-outlet mechanism 3 includes a front-end outlet wheel assembly 31 and a rear-end outlet wheel assembly 32. A cable feeding guide mechanism 33 is provided between the front-end outlet wheel assembly 31 and the rear-end outlet wheel assembly 32. The cable feeding guide mechanism 33 includes a second bracket 330 fixed on the base of the dual-outlet mechanism 3. A guide bracket 331 is provided on the second bracket 330, and a guide rail 332 is provided on the guide bracket 331. A second motor 333 is provided on the second bracket 330. The shaft of the second motor 333 is connected to a rotating rod 334 that is rotatably fixed inside the guide bracket 331. A guide member 335 is sleeved on the rotating rod 334 and the guide rail 332.

[0020] The guide member 335 has a front guide wheel 336, which guides the cashmere fibers from the front exit roller group 31 to the collecting roller mechanism 4. The front guide wheel 336 is sleeved on a first rotating shaft, which is fixed to a first bracket. The first bracket is integrally formed with the guide member 335. A pair of first limiting rods are also provided at the front of the guide member 335 to restrict the movement of cashmere fibers. The guide member 335 also has a rear guide wheel 337, which guides the cashmere fibers from the rear exit roller group 32 to the collecting roller mechanism 4. The rear guide wheel 337 is sleeved on a second rotating shaft, which is fixed to a second bracket. The second bracket is integrally formed with the guide member 335. A pair of second limiting rods are also provided at the rear of the guide member 335 to restrict the movement of cashmere fibers. Both guide wheels are used to guide the fibers from the front and rear exit roller groups 31 and 32, respectively. This design allows the two fibers to be laid evenly and smoothly onto the collecting roller 41, laying the foundation for subsequent uniform combing and cooling.

[0021] Furthermore, in this embodiment, both the front-end reel assembly 31 and the rear-end reel assembly 32 are equipped with independent power support mechanisms and braking mechanisms 38. The power support mechanism includes a power motor 34 fixed to the base of the dual-reel mechanism 3, and a pair of brackets 35 fixed to the base of the dual-reel mechanism 3. Each bracket 35 contains a rotating shaft 36 for loading and unloading the reel. A cylinder 37 for controlling the extension and retraction of the rotating shaft 36 is located on the bracket 35 furthest from the power motor 34. The power support mechanism uses the cylinder 37 to control the extension and retraction of the rotating shaft 36 within one side of the bracket 35, making the installation and removal of the reel very convenient.

[0022] The braking mechanism 38 includes a brake bracket 380 fixed between a pair of brackets 35. A brake cylinder 381 is mounted on the brake bracket 380. The extension rod of the brake cylinder 381 is connected to a transmission rod 382. The transmission rod 382 is rotatably fixed to the bracket 35, and the other end of the transmission rod 382 is connected to a brake disc 383. The brake disc 383 is rotatably connected to a first rotating rod 384 fixed to the base of the double-outlet mechanism 3. This braking mechanism 38, through the brake cylinder 381 pushing the transmission rod 382, ​​causes the brake disc 383 to actuate, achieving rapid braking of the rotating shaft, thereby precisely controlling the feeding tension and preventing yarn loosening.

[0023] In this embodiment, after the cashmere fibers are drawn out from the double-outlet mechanism 3, they enter the interior of the outer casing 2 and first pass through the collecting roller mechanism 4. The collecting roller mechanism 4 includes a collecting roller 41, whose two ends are supported by bearing seats 42, which are fixedly installed at the top of the telescopic rod of the lifting cylinder 43. By controlling the lifting cylinder 43, the height of the collecting roller 41 can be adjusted as a whole, thereby performing preliminary bundling and thickness control on the passing fiber layer.

[0024] The fibers then enter the carding mechanism 5. The carding mechanism 5 includes a carding roller 51 with at least two rows of teeth on its outer surface, the teeth being used to open and card the fibers. Both ends of the carding roller 51 are fixed to a carding support 52 located on the support base 1 via bearing seats, with one end of the carding roller 51 connected to a servo motor 53. The carding mechanism 5 also includes an auxiliary carding plate 54, which is mounted on an auxiliary support 55. The auxiliary support 55 is fixed by a pair of displacement cylinders 56, which are fixed to the support base 1. The auxiliary support 55 has a dust guide groove 57 that guides dust into the air-cooled dust collection mechanism 6. The displacement cylinders 56 allow for precise adjustment of the distance between the auxiliary carding plate 54 and the carding roller 51 to accommodate the carding requirements of different fibers.

[0025] In this embodiment, the air-cooled dust collection mechanism 6 includes a blower 61 fixed to the lower surface of the support base 1. A pipe 62 is connected to the blower 61, and a funnel component 63 is provided on the side of the pipe 62. The inlet of the funnel component 63 communicates with the inside of the outer casing 2 through a through hole opened on the support base 1. One end of the pipe 62 is connected to a storage tank 64. The blower removes heat and dust located inside the outer casing, and the dust is stored in the storage tank for periodic unified treatment.

[0026] The working principle of the air-cooled dust collection mechanism 6 is as follows: when the blower 61 is working, a strong negative pressure is generated in the pipe 62. The suction force generated by this negative pressure draws in the high-temperature air from inside the outer casing 2, especially the area of ​​the combing mechanism 5, along with dust and short fibers generated during the combing process, through the funnel part 63. The dust-laden hot air is transported along the pipe 62 and finally enters the storage tank 64. The dust settles in the storage tank and is periodically and uniformly treated, while the air is discharged. This process continuously removes heat from the inside of the equipment, achieving efficient air-cooling and cooling, while simultaneously completing dust collection and cleaning. The dust guide groove 57 effectively guides the dust combed off the fibers and accumulated near the auxiliary combing plate 54 to the suction port of the air-cooled dust collection mechanism 6, which is located near the top of the funnel part 63, greatly improving the efficiency and accuracy of dust removal.

[0027] The workflow of the entire technical solution is as follows: Two rolls of cashmere fibers are respectively installed on the shafts 36 of the front-end output roller group 31 and the rear-end output roller group 32. After the equipment is started, the dual output mechanism 3 begins to release the fibers, and the guide component 335 of the output guide mechanism 33 begins to reciprocate, guiding the two fibers alternately or synchronously to the collecting roller mechanism 4. After the fibers are bundled by the collecting roller 41, they enter the carding mechanism 5, where they are opened and carded by the carding roller 51 and the auxiliary carding plate 54. At the same time, the air-cooled dust collection mechanism 6 also starts to work. The high temperature and dust generated by carding are sucked downwards, guided by the dust guide groove 57 and collected by the funnel component 63, and enter the pipe 62. The dust is captured in the storage tank 64, and the hot air is discharged, thereby achieving continuous cooling and cleaning. Finally, the clean cashmere fibers after cooling and preliminary carding are transported to the main body of the cashmere carding machine for subsequent carding.
