Description

Technical Field

[0001] This invention relates to the field of rabbit fur processing technology, specifically to a rabbit fur combing and suction transfer device. Background Technology

[0002] Rabbit hair is woven from the very fine downy hairs at the base of rabbit fur. Rabbit hair fibers are fine, have a strong downy feel, and have neat and smooth surface scales. It combines the softness of cashmere and the smoothness of silk. In addition, rabbit hair fibers have a porous medullary cavity layer, so they are warmer than cashmere and have better moisture absorption and breathability than other natural fiber yarns (wool yarns). They also have skin-care properties.

[0003] The raw rabbit down harvested from farms contains many impurities, including rabbit down, rabbit hair, dust, weeds, and some skin. Therefore, it is necessary to extract the rabbit down from the raw down. Combing is one step in the extraction process. Combing involves separating and combing, and it is generally done by combing the raw down with the teeth of the combing rollers.

[0004] Because a single combing process is insufficient to effectively separate impurities from rabbit hair and to properly comb the rabbit hair fibers, multiple combing processes are required in actual production. Production lines typically use multiple combing machines connected end to end, resulting in complex equipment, large footprint, and high production costs. Furthermore, current technology does not provide a way to adjust the density of the combing roller teeth during multiple combing processes.

[0005] Before the raw fleece is combed, the fibers and impurities are tightly intertwined. If it is combed with extremely dense combing rollers from the beginning, the fibers will easily break, affecting the quality of the rabbit fleece. Summary of the Invention

[0006] This invention provides a rabbit down combing and suction transfer device, which features adjustable combing roller tooth density that maintains equal spacing. It works in conjunction with a recycling and circulation device to perform multi-stage combing of the rabbit down, from sparse to dense tooth density. Furthermore, it utilizes a pre-combing mechanism to improve the combing effect and the quality of the finished rabbit down product. This also increases production efficiency and reduces production costs. It solves the problems mentioned in the background art, where existing technologies require multiple combing processes for rabbit down, production lines typically use multiple combing machines connected end-to-end, resulting in complex equipment, large footprint, high production costs, and the inability to adjust the combing roller tooth density during multiple combing processes, leading to easy breakage of the down fibers and affecting the quality of the rabbit down.

[0021] As an optional solution of the rabbit fur combing and suction transfer device of the present invention, the second pre-combing mechanism further includes two turntables rotatably disposed on the third housing, and a first connecting rod is disposed on the two turntables, and the combing tooth plate is rotatably disposed on the first connecting rod.

[0022] The comb tooth plate is provided with a second connecting rod, the third housing is provided with a guide groove, the second connecting rod is slidably disposed in the guide groove, the third housing is provided with a fourth motor, and the output shaft of the fourth motor is connected to one of the turntables.

[0023] The present invention has the following beneficial effects:

[0024] 1. Compared with traditional combing equipment that requires multiple combing machines for multiple combing operations, this rabbit down combing and transfer device uses a conveyor belt to transport rabbit down, which is then combed by the combing mechanism. After one combing operation, the down is collected and circulated by a collection and circulation mechanism, and then the conveyor belt is used for subsequent combing operations multiple times.

[0025] First, the raw wool is placed into the feed port at the top of the second housing and fed onto the conveyor belt. During the conveying process, the second motor drives the combing roller and several combing roller teeth to rotate at high speed in the opposite direction to the conveyor belt to comb and remove impurities and short fibers from the raw wool.

[0026] The rabbit hair, after being combed once, is then conveyed by a conveyor belt into a circulating pipe, where a pneumatic conveying device returns the rabbit hair to the feeding port of the second housing, thus saving the area occupied by the device and reducing production costs.

[0027] 2. Unlike traditional combing equipment where the spacing between the combing roller teeth is fixed, the spacing between the combing roller teeth in this device is adjustable. Initially, the down fibers and impurities are tightly intertwined; using the densest combing roller teeth at this stage can easily cause the down fibers to break.

[0028] Therefore, during the first combing operation of this device, the teeth of the combing rollers are relatively far apart. However, during subsequent second and subsequent combing operations, the operation of a third motor causes several threaded segments with a pitch that changes in an arithmetic sequence to rotate. This causes the teeth of the combing rollers on the left and right sides to move closer to the middle part of the combing rollers. During this process, the spacing between the teeth of the combing rollers remains equal, ensuring that the combing of the rabbit wool is uniform.

[0029] 3. In this rabbit down combing and suction transfer device, while the second motor drives the combing roller to rotate, the first and second gears drive the cleaning roller to rotate at a faster speed opposite to the combing roller. This cleans the short down and impurities adhering to the combing roller, which are then thrown upwards and discharged outside the first housing under the suction of the fan. This prevents the combing roller and its teeth from being affected by increased load from adhering materials.

[0030] 4. Before the actual combing, the rabbit down combing and suction transfer device includes two pre-combing steps. When the rabbit down enters the second housing, it is first screened on the filter plate by a vibrating motor to remove some impurities, and then dispersed by vibration to facilitate subsequent combing. The rabbit down then falls onto the conveyor belt and is continuously scraped and combed by the combing tooth plate driven by a fourth motor. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] In the existing technology, the combing of rabbit hair requires multiple processes and the equipment used is relatively complex. Generally, multiple combing machines are needed, which occupy a large area and have high production costs. Moreover, the density of the combing roller teeth 304 on the combing roller 302 is fixed. If the raw hair is combed with a relatively dense combing roller teeth 304 from the beginning, it is easy to cause the rabbit hair fibers to break and affect the quality of the rabbit hair. Therefore, Example 1 is proposed.

[0040] Please see Figures 1-5 A rabbit fur combing and suction transfer device includes a base 1, a conveying mechanism 2 on the base 1 for conveying materials, the conveying mechanism 2 includes two conveying rollers 201 rotatably mounted on the base 1, a conveyor belt 202 on the two conveying rollers 201, a first motor 203 on the base 1, and the output shaft of the first motor 203 is connected to one of the conveying rollers 201.

[0041] A combing mechanism 3 is provided on the base 1 for multi-stage combing of materials. The combing mechanism 3 includes a first housing 301 provided on the base 1, a combing roller 302 rotatably provided on the first housing 301, and a second motor 303 provided on the base 1, and the output shaft of the second motor 303 is connected to the first housing 301.

[0042] A plurality of combing roller teeth 304 are slidably arranged on the combing roller 302, and the plurality of combing roller teeth 304 are equidistantly arranged. A lead screw 305 is rotatably arranged inside the combing roller 302. The lead screw 305 includes a plurality of threaded sections 306. Each of the plurality of combing roller teeth 304 is provided with a nut 307, and the plurality of nut 307 are respectively threadedly connected to the plurality of threaded sections 306.

[0043] Several threaded segments 306 are symmetrically divided into two groups based on the central axis of the combing roller 302. The threaded directions of several threaded segments 306 in each group are the same, and the pitch increases from the outside to the inside of the combing roller 302 in an arithmetic sequence. The threaded directions of the two groups of threaded segments 306 are opposite.

[0044] The combing mechanism 3 also includes a third motor 308 disposed on the first housing 301, and the output shaft of the third motor 308 is connected to the combing roller 302. Two limiting pieces 309 are disposed on each of the several threaded sections 306.

[0045] In this embodiment: Two conveyor rollers 201 are installed in a front-to-back rotation. The two conveyor rollers 201 are driven by a conveyor belt 202, which is used to transport materials. A first motor 203 is installed on the base 1. The first motor 203 runs at low speed, which drives the conveyor roller 201 located on the front side to rotate, thereby driving the conveyor belt 202 to move the rabbit fur backward.

[0046] A first housing 301 is installed on the base 1. The two ends of the combing roller 302 are rotatably installed on the inner walls of the left and right sides of the first housing 301. Several combing roller teeth 304 are slidably installed on the combing roller 302. The several combing roller teeth 304 are evenly distributed to ensure that the combing of rabbit hair is uniform.

[0047] A second motor 303 is installed on the first housing 301. The second motor 303 drives the combing roller 302 and several combing roller teeth 304 to rotate, and the direction of rotation is opposite to the conveying direction of the conveyor belt 202. The rotation speed is much greater than the conveying speed of the conveyor belt 202. The rabbit wool conveyed on the conveyor belt 202 is combed by the rotation of the several combing roller teeth 304.

[0048] Furthermore, since several combing rollers 304 are slidably installed, their spacing density is adjustable. Similar to combing hair, in the raw down, the down, hair, and impurities are tightly entangled together. In this case, using dense combing rollers 304 to comb can easily lead to the breakage of the down fibers.

[0049] Therefore, when combing rabbit hair for the first time, a larger interval can be used. After the first combing is completed, the rabbit hair is collected and put back on the conveyor belt 202 for transportation. When combing for the second time, the spacing of several combing roller teeth 304 is adjusted to be denser, and then the spacing is gradually reduced in the subsequent combing.

[0050] In order to adjust the spacing of several combing roller teeth 304 in an equidistant manner to ensure uniform combing of rabbit hair, a lead screw 305 is rotatably installed on the left inner wall of the combing roller 302, and a third motor 308 is installed on the right inner wall. The output shaft of the third motor 308 is coaxially fixed with the lead screw 305.

[0051] First, the lead screw 305 is divided into left and right parts, each consisting of several threaded segments 306. On the left side of the lead screw 305, the pitch of the threaded segments 306 increases in an arithmetic progression from the center of the lead screw 305 to the left. On the right side of the lead screw 305, the pitch of the threaded segments 306 increases in an arithmetic progression from the center of the lead screw 305 to the right. The thread directions of the threaded segments 306 on both sides are opposite. Nuts 307 are installed in the middle of several combing roller teeth 304, and these nuts 307 are threaded onto the threaded segments 306 respectively.

[0052] Since the lead screw 305 is a single-start lead screw, its pitch lead is equidistant. That is, when several thread segments 306 rotate the same number of times, the movement distance of several thread nuts 307 follows an arithmetic progression. Therefore, the distance between several thread nuts 307 and several combing roller teeth 304 in a set remains equidistantly varied. Combining the left and right parts of the lead screw 305, when the third motor 308 operates, the effect is that the several combing roller teeth 304 are divided into two parts around the central axis of the combing roller 302. The several combing roller teeth 304 move from the left and right sides towards the middle part of the combing roller 302, maintaining equidistant variation during the approach process. At this time, the several combing roller teeth 304 slide along the combing roller 302, thus acting as a limit, allowing the several combing roller teeth 304 to maintain displacement in the left and right directions.

[0053] Similarly, when the third motor 308 rotates in the reverse direction, several combing roller teeth 304 expand to the left and right sides from the central axis of the combing roller 302, maintaining equidistant changes during the expansion process. After adjustment, the third motor 308 stops rotating, and the self-locking property between the lead screw 305 and the lead nut 307 fixes the position of the several combing roller teeth 304.

[0054] Two limiting pieces 309 are installed on each threaded section 306. The two limiting pieces 309 are located on the left and right sides of the nut 307 respectively, and play a limiting role to prevent some nut 307 and some combing roller teeth 304 from displacing beyond the limit and colliding together.

[0055] It should be further explained that during combing, the combing roller 302 is generally used to comb the rabbit wool conveyed in the opposite direction. For example, in the prior art document 1CN202120966431.9, a cashmere combing machine combing tooth hair removal device, the cashmere is conveyed by a conveyor belt, and a combing shaft is installed above the conveyor belt for combing. In this invention, a conveyor belt 202 is also used to convey the cashmere. A suitable conveying equipment can be selected according to actual needs to convey the rabbit wool, and it is also driven by a motor to rotate in the opposite direction to the combing roller 302, which does not affect the technical solution of this invention.

[0056] Example 2

[0057] Since several combing roller teeth 304 are adjustable, there are gaps between them, which need to be sealed. Otherwise, the rabbit hair will be rolled into the combing roller 302. Therefore, Example 2 is proposed.

[0058] This embodiment is an improvement upon embodiment 1. Please refer to the following description. Figures 2-5 The combing mechanism 3 also includes several first connecting rings 310 and several second connecting rings 311, which are respectively connected to several combing roller teeth 304.

[0059] In this embodiment: except for the rightmost combing roller tooth 304, each combing roller tooth 304 has a second connecting ring 311 installed on its left end and a first connecting ring 310 installed on its right end. The right end of the first connecting ring 310 is an annular opening. The relationship between adjacent first connecting rings 310 and second connecting rings 311 is that the second connecting ring 311 is slidably installed in the opening at the right end of the first connecting ring 310 and maintains a good seal.

[0060] The left and right inner walls of the combing roller 302 are configured with the same opening as the right end of the first connecting ring 310. The second connecting ring 311 at the left end of the leftmost combing roller tooth 304 is slidably installed on the left inner wall of the combing roller 302. The left and right ends of the rightmost combing roller tooth 304 are both fixed with the second connecting ring 311, and the second connecting ring 311 at its right end is slidably installed on the right inner wall of the combing roller 302.

[0061] This ensures that the combing roller teeth 304 remain sealed together without gaps, whether they are moving towards the center of the combing roller 302 or expanding to the left and right sides, preventing rabbit hair from getting into the combing roller 302.

[0062] Example 3

[0063] In order to collect the rabbit wool that has been combed once by the combing mechanism 3 and circulate it back to the conveyor belt 202 for secondary and multiple combing, Example 3 is proposed.

[0064] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-2 The base 1 is provided with a collection and circulation mechanism 4 for collecting the material on the conveying roller 201 and sending it back to the conveying roller 201 to achieve multi-stage combing. The collection and circulation mechanism 4 includes a circulation pipe 401 provided on the base 1.

[0065] One end of the circulation pipe 401 is located at the tail end of the conveying roller 201, and the circulation pipe 401 is equipped with a pneumatic conveying device 402 and a discharge valve 403.

[0066] In this embodiment: a circulation pipe 401 is installed on the base 1. One end of the circulation pipe 401 is located at the tail end of the conveyor belt 202 and is used to catch the rabbit fur falling from the conveyor belt 202, while the other end of the circulation pipe 401 leads to the head end of the conveyor belt 202.

[0067] A pneumatic conveying device 402, such as a blower, is installed on the circulation pipe 401. The pneumatic conveying device 402 transports the rabbit wool collected in the circulation pipe 401 to the conveyor belt 202. The discharge valve 403 is used to remove the collected rabbit wool from the circulation pipe 401 after the final multiple combing stages, completing the final processing. At this point, the pneumatic conveying device 402 should be stopped.

[0068] Example 4

[0069] After a long period of operation, the combing roller 302 and several combing roller teeth 304 will inevitably have short fibers, impurities, etc. adhering to their surfaces, which will increase the load and make it difficult to continue combing. Therefore, Example 4 is proposed.

[0070] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-3 The first housing 301 is provided with a cleaning mechanism 5 for transferring impurities swept out of the material by a number of combing roller teeth 304 by air suction. The cleaning mechanism 5 includes a cleaning roller 501 rotatably disposed on the first housing 301.

[0071] The cleaning mechanism 5 also includes a first gear 502 disposed on the cleaning roller 501, and a second gear 503 disposed on the combing roller 302. The first gear 502 meshes with the second gear 503, and the transmission ratio between the second gear 503 and the first gear 502 is greater than one.

[0072] The cleaning mechanism 5 also includes a suction fan 504 mounted on the first housing 301. The suction port of the suction fan 504 is aligned with the cleaning roller 501, and a discharge pipe 505 is provided at the exhaust port of the suction fan 504.

[0073] In this embodiment: a cleaning roller 501 is rotatably mounted on the first housing 301, and the cleaning brush on the surface of the cleaning roller 501 contacts the combing roller 302. By rotating the cleaning roller 501 in the opposite direction to the combing roller 302, short fibers and impurities adhering to the combing roller 302 are swept off and thrown upwards at high speed. These are then sucked away by the suction fan 504 mounted on the first housing 301 and discharged through the discharge pipe 505.

[0074] To save on operating costs, a separate motor is not used. The cleaning roller 501 and the combing roller 302 are connected by a first gear 502 and a second gear 503. When the second motor 303 is running, it also drives the cleaning roller 501 to rotate. Since the diameter and number of teeth of the first gear 502 are smaller than those of the second gear 503, the rotational speed of the cleaning roller 501 is higher than that of the combing roller 302, which is beneficial for cleaning.

[0075] It should be noted that a scraper can be installed on the inner wall of the first housing 301 to form a sealed channel with the combing roller 302. For details, please refer to the setting of the "triangular dust removal knife" in the prior art document 1.

[0076] Example 5

[0077] Since some large particles and other impurities are difficult to clean by combing and also cause wear to the combing roller teeth 304, pre-combing is required before combing. Therefore, Example 5 is proposed.

[0078] This embodiment is an improvement upon embodiment 4. For details, please refer to [link / reference]. Figures 1-2 The base 1 is provided with a first pre-combing mechanism 6, which includes a second housing 601 provided on the base 1, and a filter plate 602 and a vibration motor 603 provided on the second housing 601.

[0079] The filter plate 602 divides the inner cavity of the second housing 601 into upper and lower chambers, with the upper chamber corresponding to the other end of the circulation pipe 401.

[0080] In this embodiment: a second housing 601 is installed on the base 1. The upper opening of the second housing 601 is aligned with the other end of the circulation pipe 401. The inner cavity of the second housing 601 is divided into upper and lower parts by the filter plate 602. Initially, the raw wool is put in through the upper opening of the second housing 601, and subsequently it is transported through the circulation pipe 401.

[0081] As the rabbit fur slides down the filter plate 602 under the action of gravity, it is vibrated and screened by the vibration motor 603 installed on the second housing 601 to remove some impurities, and at the same time, it can also break up large clumps of rabbit fur.

[0082] It should be noted that, in actual use, the second housing 601 can be fitted with a shock-absorbing structure.

[0083] Example 6

[0084] To further improve the pre-combing effect, Example 6 is proposed;

[0085] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figures 1-4 The base 1 is also provided with a second pre-combing mechanism 7, which includes a third housing 701 disposed on the base 1, and a combing tooth plate 702 disposed inside the third housing 701.

[0086] The second pre-combing mechanism 7 also includes two turntables 703 rotatably mounted on the third housing 701, and a first connecting rod 704 is mounted on the two turntables 703. The combing tooth plate 702 is rotatably mounted on the first connecting rod 704.

[0087] A second connecting rod 705 is provided on the comb tooth plate 702, and a guide groove 706 is provided on the third housing 701. The second connecting rod 705 is slidably disposed in the guide groove 706. A fourth motor 707 is provided on the third housing 701, and the output shaft of the fourth motor 707 is connected to one of the turntables 703.

[0088] In this embodiment: a third housing 701 is installed on the base 1, and turntables 703 are rotatably installed on the left and right inner walls of the third housing 701. A first connecting rod 704 is fixed between the two turntables 703, and a combing plate 702 is rotatably installed on the first connecting rod 704. A second connecting rod 705 fixed on the combing plate 702 slides along the guide groove 706.

[0089] When the fourth motor 707 drives the turntable 703 and the first connecting rod 704 to rotate, the combing plate 702 moves eccentrically along the trajectory of the guide groove 706, continuously scraping and combing the rabbit fur on the conveyor belt 202.

[0090] It should be noted that a conveyor belt can be used to connect the turntable 703 and the combing roller 302 for transmission, thus saving the need for a fourth motor 707.

[0091] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0092] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
