Description

Technical Field

[0001] This utility model belongs to the field of fiber pretreatment technology, and particularly relates to a burr breaking or removal device related to carding machines or other pretreatment machinery, specifically a cashmere fabric impurity cleaning device. Background Technology

[0002] Cashmere combing is a technique used to separate coarse hair, dander, and other impurities to obtain dehaired cashmere for spinning. In existing technologies, coarse hair, dead hair, and dander are generally separated by mechanical combing.

[0003] In the prior art, the above-mentioned impurities are generally removed through a combing stage. For example, CN219824473U discloses a cashmere combing and impurity removal device. The device uses the rotation of the combing roller to break up the cashmere by the combing teeth on the combing roller and the slicing teeth on the conveyor belt, separating the impurity particles in the cashmere. The impurity particles are guided downward through the through holes on the conveyor belt and into the dust removal component through the air outlet screw to remove the impurities.

[0004] However, the aforementioned device cannot further process the already combed cashmere. In some scenarios where the quality of the fabric is required to be high, such as baby products, the remaining impurities are often quite small and can easily cause skin irritation when they adhere to the cashmere clothing, thus reducing the quality of the clothing. Utility Model Content

[0005] The purpose of this invention is to provide a cashmere fabric impurity cleaning device, which further reduces residual impurities in cashmere by setting a lever with impurity removal holes after combing.

[0006] The technical solution adopted by this utility model to solve the above problems is: a cashmere fabric impurity cleaning device, including a transmission unit, a combing unit, and a flattening unit, wherein the flattening unit is located downstream of the combing unit along the transmission direction of the transmission unit; the transmission unit includes a support and a conveyor belt mounted on the support; the combing unit includes a feeding housing and a combing roller located in the feeding housing; the flattening unit includes a lever assembly, the lever assembly includes a lever mounting plate and a plurality of levers mounted on the end face of the lever mounting plate; The lever has a lever cavity inside, and the lever has several impurity removal holes that communicate with the lever cavity. The lever cavity is connected to the air intake device.

[0007] A further preferred technical solution is that: the lever mounting plate has a mounting plate cavity, the mounting plate cavity is connected to several lever cavities, and the air intake device is also connected to the mounting plate cavity.

[0008] A further preferred technical solution includes a filter unit, which includes a filter housing and a fan hole and a dust suction hole. The filter unit also includes a dust suction component, which includes a dust suction pipe installed in the dust suction hole, a dust suction hood installed at the inlet of the dust suction pipe, and a dust suction fan installed in the fan hole.

[0009] A further preferred technical solution is that the suction device is a dust removal pipe that is connected to the suction pipe and the cavity of the mounting plate.

[0010] A further preferred technical solution is that the lever is equipped with several sieve plates.

[0011] A further preferred technical solution is that the impurity removal hole is set on the screen plate, and the lever cavity extends to the screen plate.

[0012] A further preferred technical solution is that the feed housing includes a front panel, a back panel and two side panels, the bottom of the front panel is provided with a discharge port, the bottom of the back panel is provided with a feed port, and the bottom opening of the discharge port is open.

[0013] A further preferred technical solution is that the lever mounting plate is located on the upper side of the discharge port.

[0014] A further preferred technical solution is that the lever assembly further includes a lifting screw rotatably connected to the upper end of the lever mounting plate, a screw mounting plate disposed on the front panel and located at the upper end of the lever mounting plate, and a lifting screw hole disposed on the screw mounting plate for screwing the lifting screw.

[0015] A further preferred technical solution is that the lever assembly also includes a guide rod hole disposed on the lead screw mounting plate, and a guide rod disposed on the upper end of the lever mounting plate and passing through the guide rod hole.

[0016] In summary, this utility model has the following advantages: 1. This utility model, by setting a flattening unit after combing, utilizes the impurity removal hole and suction device on the lever to effectively remove residual fine impurities from cashmere, significantly reducing the impurity content. Compared with the prior art that removes impurities during the combing stage, its removal effect is more significant, further improving the quality of cashmere. For sensitive applications, by reducing impurity residue, it avoids skin irritation caused by impurities adhering to clothing, thereby improving product comfort and overall quality.

[0017] 2. This utility model utilizes the coordinated operation of the lever cavity, the mounting plate cavity, and the filter unit to centrally filter and process impurities after they are sucked in, preventing impurities from flying away or re-contaminating cashmere and improving cleaning efficiency. 3. The lever of this utility model is equipped with a sieve plate, and the impurity removal hole is located on the sieve plate, which can better separate and capture tiny impurities and enhance the cleaning effect; 4. The lever assembly of this utility model is equipped with a lifting screw and a guide rod, which allows for adjustment of the lever height to adapt to different cashmere thicknesses or processing needs, and optimizes the impurity cleaning process.

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0034] Reference Appendix Figure 1-13 First, this embodiment describes the specific form of a cashmere combing machine used in cashmere processing, to which the cashmere fabric impurity cleaning device is applied. This cashmere combing machine includes: The machine consists of a drive unit, a combing unit, a filtering unit, and a flattening unit. The drive unit provides power and transmits motion, driving the entire machine. It controls the feeding speed of the raw materials, the coordinated operation of each working part, and the final product output. The combing unit performs core processing on the cashmere raw materials. Using a high-speed rotating cylinder with fine combing needles and a relatively stationary working panel with combing needles, it opens, combs, and separates the fibers, breaking down tangled cashmere bundles into individual fibers. It also separates and removes as much coarse hair, dander, and plant impurities as possible from the cashmere. The filtering unit removes short fibers, loose hairs, dust, and other fine impurities separated during the combing process. It typically uses airflow or a filter structure to collect and remove the separated waste, ensuring the cleanliness of the processing area and product quality. The flattening unit further processes the loose fiber web from the combing unit to improve its quality.

[0035] The transmission unit includes a support frame 1, a conveyor belt 2 mounted on the support frame 1, conveyor teeth 201 on the inner side of the conveyor belt 2, a conveyor roller 3 meshing with the conveyor teeth 201 via conveyor roller teeth 301, a conveyor roller shaft 302 mounted on the conveyor roller 3, and a transmission motor 4 connected to the conveyor roller shaft 302 via a rotor. The support frame 1 supports and fixes the entire transmission unit, ensuring that each component operates stably in the correct position. The conveyor belt 2 carries and transports the cashmere raw materials to be processed, serving as the main conveying device for inputting, conveying, and outputting the raw materials through each working unit. The conveyor teeth 201 are located on the inner side of the conveyor belt 2 and mesh with the conveyor roller teeth 301 to transmit power. These teeth ensure that the conveyor belt 2 is precisely pulled by the conveyor roller 3, preventing slippage and ensuring that the conveyor belt speed is consistent with the driving force. The transmission motor 4 provides rotational power, serving as the power source for the entire transmission unit. Its rotor directly drives the conveyor roller shaft 302, thereby driving the conveyor roller 3 to rotate and ultimately drive the conveyor belt 2.

[0036] The combing unit includes a feed housing 5, which includes a front panel 503, a back panel 505, and two side panels 504. The bottom of the front panel 503 is provided with a discharge port 501, and the bottom of the back panel 505 is provided with a feed port 506. The bottom opening of the discharge port 501 is open. The side panels 504 are provided with combing roller holes 502. The combing unit also includes a combing roller 6, which is provided with a plurality of comb teeth 601. The side of the combing roller 6 is provided with a combing roller shaft 602, which is installed in the combing roller hole 502. The feed housing 5 forms a semi-enclosed guide channel and working chamber. It is responsible for safely and smoothly guiding the cashmere raw material to be combed from the feed inlet 506 to the combing working area. It can also perform preliminary collection and restraint on the raw material before it enters the combing area to prevent the raw material from scattering and ensure continuous and uniform feeding. The internal design helps guide airflow or contain the small amount of loose or short fibers generated during the feeding process to prevent them from splashing everywhere. It can also provide a mounting base and necessary space sealing for other internal or adjacent components. The front panel 503, back panel 505, two side panels 504, and a top plate if necessary, together form the main body of the feed housing 5. The function of the combing roller 6 is to pre-comb and convey the cashmere entering the feed housing 5. It uses the comb teeth 601 to tear large pieces of raw material, initially separating entangled fibers. The gaps between the comb teeth intercept large particles of impurities such as grass clippings. The rotation direction pushes the raw material toward the discharge port 501. The comb teeth 601 are designed in the shape of needles or serrations, directly contacting the cashmere raw material to perform opening, impurity removal, and pushing actions. The combing roller shaft 602 passes through the main body of the combing roller, transmits the driving torque, and is embedded at both ends in the combing roller holes 502 of the side panel 504.

[0037] Two combing rollers 6 are provided. The combing unit also includes sprockets 603 respectively mounted on the two combing roller shafts 602, chains 604 meshing with the two sprockets 603 respectively, and a combing motor fixedly connected to either combing roller shaft 602 via a rotor. Using two combing rollers 6 increases the pretreatment area and further improves the uniformity of raw material opening. The sprockets 603 are fixed to the ends of the combing roller shafts 602 and mesh with the double sprockets 603 via chains 604, forming a closed transmission ring that accurately transmits power and prevents slippage. The combing motor, as the power source, outputs torque through the rotor and can drive both combing rollers 6 to rotate simultaneously by connecting only one combing roller shaft 602. Furthermore, the two sprockets 603 have the same number of teeth, which forces the two combing rollers 6 to rotate synchronously at the same speed. Furthermore, the two sprockets 603 have different numbers of teeth, which can force the two combing rollers 6 to rotate at different speeds, enabling differential processing of raw materials. For example, the combing roller 6 closer to the front panel 503 rotates at a higher speed than the combing roller 6 closer to the back panel 505, which increases the pulling force.

[0038] The filtration unit includes a filter housing 7 with a sliding groove 704; a filter plate 8 with several filter holes 801 and a sliding block 802 installed in the sliding groove 704 on its side; and a vibration unit with an elastic rod 9 disposed inside the filter housing 7 and between the filter plate 8. The filter housing 7 forms the main frame and airflow channel of the filtration unit, providing installation space for the filter plate 8 and guiding the airflow containing impurities. Except for necessary pore structures, the filter housing 7 is essentially a sealed structure, but typically does not require an airtight rating; it only needs to prevent fiber and dust leakage and meet industrial dust removal standards. The sliding groove 704 is located on the upper and lower inner sides of the filter housing 7 to guide the sliding block 802 of the filter plate 8 to slide within it. The high-frequency micro-motion mechanism shakes impurities adhering to the filter plate 8 into the filter housing 7, allowing the filter plate 8 to quickly reset and improving the vibration effect.

[0039] The elastic rod 9 includes an outer tube 901 that sleeves the inner push rod 902, and a return spring 903 disposed in the outer tube 901 for pushing the inner push rod 902 outward. The outer tube 901 provides rigid support and a guide rail for the inner push rod 902, and the return spring 903 stores the energy when the inner push rod 902 retracts into the outer tube 901, and releases the energy to return the inner push rod 902 to its original position after the external pressure is removed.

[0040] The filter housing 7 is also equipped with a fan hole 701 and a dust suction hole 702. The filter unit also includes a dust suction component 11, which includes a dust suction pipe 1101 installed in the dust suction hole 702, a dust suction hood 1102 located at the inlet of the dust suction pipe 1101, and a dust suction fan 12 installed in the fan hole 701. The fan hole 701 is a dedicated interface for installing the dust suction fan 12, located on the clean airflow side of the filter housing 7, and the dust suction fan 12 is sealed to the fan hole 701. The dust suction hole 702 is located on the dust-laden airflow side of the filter housing 7 and is used to connect the dust suction pipe 1101. The dust suction hood 1102 is installed at the outer end of the dust suction pipe 1101 and is located in the feed housing 5. When the raw material is loosened by the combing roller, it uses negative pressure to adsorb the flying dust, short fibers, grass clippings, and other light impurities into the filter housing 7. Furthermore, the filter housing 7 is also equipped with a door, which can be opened to clean the impurities filtered in the filter housing 7.

[0041] The filter housing 7 is also provided with a connecting rod hole 703. The vibration unit also includes a connecting rod assembly 10. The connecting rod assembly 10 includes a crank pin 1001 disposed on the filter plate 8, a first connecting rod 1002 slidably installed in the connecting rod hole 703, and a second connecting rod 1004 rotatably connected to the crank pin 1001 and the first connecting rod 1002. By reciprocatingly pushing and pulling the first connecting rod 1002, the filter plate 8 can be reciprocated through the second connecting rod 1004 and the crank pin 1001, achieving a high-frequency vibration effect on the filter plate 8.

[0042] The linkage assembly 10 also includes a linkage bracket 1003 that slidably connects to the first linkage 1002. The linkage bracket 1003 improves the stability of the reciprocating push-pull of the first linkage 1002.

[0043] The linkage assembly 10 also includes a cylinder 1008 whose movable end is connected to the first linkage 1002. The cylinder 1008, as a typical component for realizing push-pull actions, is connected to the outer end of the first linkage 1002 and can achieve a push-pull effect.

[0044] The linkage assembly 10 also includes a third linkage 1005 rotatably connected to the first linkage 1002, a fourth linkage 1006 rotatably connected to the third linkage 1005, and a linkage base plate 1007 disposed at the bottom end of the fourth linkage 1006. The combing unit also includes a cam 605 disposed on the combing roller shaft 602; the cam 605 abuts against the lower end of the linkage base plate 1007. The cam 605 converts the rotational motion of the combing roller 6 into the periodic reciprocating vibration of the filter plate 8, driving the filter plate 8 to achieve automatic unclogging. Specifically, the combing roller shaft 602 drives the cam 605 to rotate at a uniform speed, causing the cam 605 to periodically press the linkage base plate 1007 upward, then push the fourth linkage 1006 to move towards the first linkage 1002, and finally cause the filter plate 8 to generate reciprocating linear vibration. The above design ensures that the generation of impurities and the removal of the filter screen 8 are matched in real time, avoiding impurities remaining on the filter screen 8 for a long time.

[0045] The cashmere spreading unit includes a lever assembly 13, which includes a lever mounting plate 1302 located above the discharge port 501, several levers 1301 disposed on the lower end face of the lever mounting plate 1302, a lifting screw 1303 rotatably connected to the upper end of the lever mounting plate 1302, a screw mounting plate 1304 disposed on the front panel 503 and located above the lever mounting plate 1302, and a lifting screw hole disposed on the screw mounting plate 1304 for screwing the lifting screw 1303. The levers 1301 can spread the cashmere placed on the conveyor surface of the conveyor, thereby ensuring that the cashmere fibers are fully loosened and reducing fiber damage. By rotating the lifting screw 1303, the lever mounting plate 1302 is moved up and down in the vertical direction, so that the height position of the levers can be adjusted, thereby ensuring that the cashmere is completely spread out.

[0046] The lever assembly 13 also includes a guide rod hole provided on the lead screw mounting plate 1304, and a guide rod 1305 provided on the upper end of the lever mounting plate 1302 and passing through the guide rod hole.

[0047] The lever assembly 13 also includes a knob block 1306 disposed at the top of the lifting screw 1303.

[0048] The following is a more detailed introduction to the specific structure of the cashmere fabric impurity cleaning device.

[0049] Example 1 A cashmere fabric impurity cleaning device, comprising: The system includes a transmission unit, a combing unit, and a spreading unit, with the spreading unit located downstream of the combing unit along the transmission direction of the transmission unit. The transmission unit includes a support 1 and a conveyor belt 2 mounted on the support 1. The combing unit includes a feed housing 5 and combing rollers 6 located within the feed housing 5. The spreading unit includes a lever assembly 13, which includes a lever mounting plate 1302 and several levers 1301 mounted on the end face of the lever mounting plate 1302. Each lever 1301 has a lever cavity and several impurity removal holes 1308 communicating with the lever cavity. The lever cavity is connected to an air suction device. The support has four corner posts, which are reinforced by reinforcing bars. A top platform for mounting the conveyor belt 2 is located at the upper end of each corner post. The levers 1301 are evenly spaced along the extension direction of the lever mounting plate 1302. Multiple levers 1301 are evenly spaced along the extension direction of the lever mounting plate 1302 on the lever mounting plate 1302. They are used to process the combed cashmere. During the processing, the impurity removal holes 1308 will penetrate deep into the cashmere during the process of lever 1301. The impurities hidden deep in the cashmere are sucked out by the air suction device. The impurity removal holes 1308 are set very small. During the flat combing process of lever 1301, the cashmere fibers will move along the travel direction of the conveyor belt 2 and very few will enter the impurity removal holes 1308.

[0050] The lever mounting plate 1302 has a mounting plate cavity, which is connected to several lever cavities. The suction device is also connected to the mounting plate cavity. The lever cavities and the mounting plate cavity together form a whole, which facilitates the simultaneous adsorption of all the impurity removal holes 1308 by a single suction device.

[0051] The system also includes a filter unit, which comprises a filter housing 7 with a fan hole 701 and a suction hole 702. The filter unit further includes a suction component 11, which includes a suction pipe 1101 installed in the suction hole 702, a suction hood 1102 located at the inlet of the suction pipe 1101, and a suction fan 12 installed in the fan hole 701. The filter housing 7 is a welded housing made of stainless steel. Sealing rubber gaskets are provided at the fan hole 701 and the suction hole 702 to secure the suction fan 12 and the suction pipe 1101, respectively. The suction hood 1102 is a flared hood located at the bottom of the suction pipe 1101. The suction pipe 1101 can be a rigid or flexible pipe; if rigid, its shape needs to be adjusted to ensure proper connection with the suction hood 1102.

[0052] The suction device is a dust removal pipe 14 that communicates with the suction pipe 1101 and the cavity of the mounting plate. The dust removal pipe 14 is a flexible pipe with a certain degree of extension to facilitate height adjustment by the lever mounting plate 1302. The suction pipe 1101 has a hole on its side for airtight connection with the dust removal pipe 14, and the cavity of the mounting plate also has a hole for airtight connection with the suction pipe 1101.

[0053] The lever 1301 is equipped with several sieves 1307. The sieves 1307 are located at the bottom of the lever 1301 and can further comb the already combed cashmere.

[0054] Impurity removal holes 1308 are provided on the sieve plate 1307, and the lever cavity extends to the sieve plate 1307. The impurity removal holes 1308 are provided on the sieve plate 1307, which can penetrate further into the cashmere to remove impurities more deeply.

[0055] The feed housing 5 includes a front panel 503, a back panel 505, and two side panels 504. The bottom of the front panel 503 is provided with a discharge port 501, and the bottom of the back panel 505 is provided with a feed port 506. The bottom opening of the discharge port 501 is open. The open bottom opening means that the discharge port 501 forms a trough space with its top edge and two sides, which facilitates the direct flow of the combed cashmere from the discharge port 501 to the conveyor belt 2 without any obstruction.

[0056] The lever mounting plate 1302 is located on the upper side of the discharge port 501. The lever mounting plate 1302 is located on the upper side of the discharge port 501 so that the freshly combed cashmere immediately comes into contact with the lever mounting plate 1302, achieving flat discharge, and can be further flattened by the lever 1301.

[0057] The lever assembly 13 also includes a lifting screw 1303 rotatably connected to the upper end of the lever mounting plate 1302, a screw mounting plate 1304 mounted on the front panel 503 and located above the lever mounting plate 1302, and a lifting screw hole mounted on the screw mounting plate 1304 for screwing the lifting screw 1303. By rotating the lifting screw 1303, the height of the lever mounting plate 1302 can be adjusted to determine the thickness of the cashmere smoothing according to the amount of cashmere output. This prevents the smoothing effect from being too high or too low, which would cause some cashmere to spread onto the lever mounting plate 1302 during the smoothing process, resulting in a more messy appearance.

[0058] The lever assembly 13 also includes a guide rod hole on the lead screw mounting plate 1304, and a guide rod 1305 disposed on the upper end of the lever mounting plate 1302 and passing through the guide rod hole. The guide rod 1305 is a vertically arranged cylindrical rod with a smooth side surface, and generally one is provided on each side of the lead screw mounting plate 1304, so that the lead screw mounting plate 1304 can always maintain vertical movement under the adjustment of the lifting lead screw 1303.

[0059] In this embodiment, the method of using the cashmere fabric impurity cleaning device is as follows: 1. Rotate the lifting screw 1303, adjust the vertical position of the lever mounting plate 1302 and lever 1301, and guide rod 1305 to ensure vertical movement. Set the optimal height according to the thickness and density of cashmere output to ensure that the screen plate 1307 at the bottom of lever 1301 can effectively contact and comb the cashmere, while preventing cashmere from accumulating above the mounting plate 1302. 2. Turn on the conveyor belt 2 of the transmission unit, the combing roller 6 of the combing unit, and the dust suction fan 12 of the filter unit. After the dust suction fan 12 starts, it generates negative pressure at the dust suction hood 1102, and through the dust suction pipe 1101, the dust removal pipe 14, the mounting plate cavity and the lever cavity, it finally creates suction at the impurity removal holes 1308 on all levers 1301. 3. The cashmere that has been preliminarily combed is fed into the feed port 506 at the bottom of the back panel 505 of the feed housing 5. The cashmere is further broken up and combed by the high-speed rotating combing roller 6 in the feed housing 5, separating out some impurities. The combed cashmere falls onto the conveyor belt 2 below it through the discharge port 501 at the bottom of the front panel 503. 4. The conveyor belt 2 carries the combed cashmere and moves it along the transmission direction. The cashmere first passes under the lever mounting plate 1302 located above the discharge port 501, and is combed and flattened by multiple equally spaced levers 1301 installed at its lower end. The screen plate 1307 penetrates into the cashmere fiber layer for fine flattening. At the same time, the small impurity removal holes 1308 on the screen plate 1307 continuously draw in air, and the hidden or residual small impurities are drawn upward into the airflow system of the device through the lever cavity and the mounting plate cavity. Because the cashmere fibers are large in size and are subjected to forward force, very few are drawn into the impurity removal holes 1308.

[0060] 5. The air containing impurities drawn in through the impurity removal hole 1308 passes through the lever cavity and the mounting plate cavity; it flows into the dust removal pipe 14; then through the suction pipe 1101, it is captured by the horn-shaped suction hood 1102; finally, the suction fan 12 draws the airflow into the filter box 7. Impurities are collected in the filter box 7, and clean air is discharged or further processed.

[0061] In addition, the lever 1301 and the lever mounting plate 1302 are detachably mounted together, for example by using internal and external threaded connections, which facilitates the periodic cleaning of impurities remaining in the lever 1301 or the lever mounting plate 1302.

[0062] Furthermore, the same or similar element symbols are used as far as possible in the accompanying drawings and description to refer to the same or similar parts or steps. The drawings are presented in a simplified form and are not drawn to scale. For convenience and clarity only, directional terms such as top, bottom, front, back, left, right, front, back, upward, above, above, below, behind, and front may be used to refer to the drawings. These and similar directional terms should not be construed as limiting the scope of this disclosure in any way.
