Description

A cashmere fiber combing device Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a cashmere fiber combing device. Background Technology

[0002] Currently, cashmere fiber combing equipment generally consists of a feeding machine, an opening mechanism, a de-coating mechanism, and a sorting and finishing mechanism connected in sequence. The existing opening mechanism comprises a feeding roller, a licker-in roller, a cylinder, and a doffer. Fibers are first fed in by the feeding roller, then initially combed by the licker-in roller, then finely combed by the cylinder, and finally, the doffer condenses the fibers on the cylinder surface into a fiber layer. The existing de-coating mechanism generally uses a multi-stage de-coating assembly composed of de-coating rollers; a small number use a dust cage-type fiber sorting device. However, regardless of the de-coating mechanism used, the existing opening mechanism has poor adaptability and struggles to create favorable conditions for subsequent de-coating and cashmere retention.

[0003] Existing dust cage type fiber combing devices have a feed plate positioned below the feed rollers, using a reverse feeding method through the cooperation of the feed plate and the feed rollers. This feeding method causes significant damage to cashmere fibers. Furthermore, dust cage type fiber combing devices are typically configured in multiple units, further increasing the damage to cashmere fibers and resulting in a short fiber content exceeding 25%.

[0004] Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0005] The purpose of this utility model is to provide a cashmere fiber combing device, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted is as follows:

[0006] A cashmere fiber combing device includes a wool feeder at the beginning and a combing machine at the end. An opening mechanism and a de-coarsening mechanism are provided between the wool feeder and the combing machine. The opening mechanism includes a primary opening unit and a secondary opening unit. The de-coarsening mechanism includes at least three sets of dust cage-type de-coarsening units connected in sequence.

[0007] The primary opening unit includes a first feed roller, a first licker roller, a breast cylinder, a first transfer roller, and a large cylinder connected in sequence. The breast cylinder is provided with two sets of opening roller assemblies spaced apart in the circumferential direction, and the large cylinder is provided with three sets of opening roller assemblies installed in the circumferential direction.

[0008] The secondary opening unit includes a second transfer roller, a coarse cylinder, a doffer, and a cutter connected in sequence. The second transfer roller is used to connect the large cylinder and the coarse cylinder. A doffer cleaning structure is installed on the top of the doffer, and at least one first support roller is provided below the cutter.

[0009] The dust cage type decoction unit includes a second idler roller, a second feed roller, a second licker roller and a dust cage connected in sequence. The first idler roller is connected to the second idler roller. A cotton feeding plate is provided above the second feed roller. The inner side of the cotton feeding plate is arc-shaped and is fitted with the second feed roller with a gap.

[0010] Preferably, the dust cage type coarsening unit has six groups.

[0011] Preferably, the opening roller assembly includes a work roller and a stripping roller.

[0012] Preferably, the doffer cleaning structure includes a cleaning roller shaft with several brush bundles on its surface. Both ends of the cleaning roller shaft are equipped with seated bearings, each seated bearing is equipped with a U-shaped bracket, and the bottom of the seated bearing is connected to the inner bottom wall of the U-shaped bracket by a spring. The left side of the seated bearing is slidably connected to the inner left wall of the U-shaped bracket, and the right side of the seated bearing is slidably connected to the inner right wall of the U-shaped bracket. Both U-shaped brackets are fixedly installed on the secondary opening unit frame. Each U-shaped bracket is provided with a pressing component above it for pressing down on the seated bearing and making the brush bundles contact the doffer.

[0013] Preferably, the pressing assembly includes a cam, which is rotatably mounted on the frame of the secondary opening unit. The cam is provided with a handle and an L-shaped locking rod. By rotating the cam with the handle, the protrusion of the cam can press down on the bearing seat and cause the bearing seat to move downward. The end of the L-shaped locking rod can be locked in a slot provided on the side wall of the U-shaped bracket to prevent the cam from rotating back.

[0014] Preferably, the pressing assembly includes a horizontal plate, which is fixedly installed at the top opening of the U-shaped bracket. The horizontal plate is provided with a set screw, which can be turned to move the bearing seat downward.

[0015] Preferably, there are two first idlers, and the two first idlers and the second idler in the adjacent dust cage type decoction unit form a V-shaped structure.

[0016] Preferably, the diameter of the chest cylinder roller is 500mm, the diameter of the large cylinder roller is 700mm, and the diameter of the coarse-rolling cylinder roller is 250mm.

[0017] Preferably, a dust cage cleaning roller is installed on the side of the dust cage away from the second needle roller and at a lower position. The surface of the dust cage cleaning roller is provided with elastic paddles along the axial direction. There are at least two elastic paddles, which are arranged at intervals along the circumference. When the dust cage cleaning roller is rotated, the outer edge of the elastic paddles contacts the dust cage and is used to peel off the lint attached to the surface of the dust cage.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model discloses a cashmere fiber combing device. The opening mechanism adopts a two-stage opening process. The first-stage opening unit performs two openings, and the second-stage opening unit performs one opening. The opening and combing effect is greatly improved, creating more favorable conditions for subsequent coarse removal and cashmere retention.

[0020] The dust cage-type decoupling unit adopts a forward feeding method. Cashmere fibers are fed in between the second feed roller and the feed plate, and then continue forward from the bottom of the second licker-in roller. The second feed roller and the second licker-in roller rotate in opposite directions. Compared with the existing feeding structure, the fiber transfer angle is smoother, which can reduce fiber breakage caused by reverse feeding and reduce the short fiber content. Even with six sets of dust cage-type decoupling units stacked, the reduction can reach about 10%. In addition, a dust cage cleaning roller is provided to clean the short fibers attached to the dust cage cylinder and prevent them from being sucked into the vent holes, causing blockage and affecting air suction.

[0021] The doffer is equipped with a doffer cleaning structure on top, which can automatically clean the residual fibers on the doffer without manual cleaning, saving time and effort and greatly improving work efficiency. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] As shown in Figure 1, a preferred embodiment of the present invention provides a cashmere fiber combing device, which includes a feeding machine, an opening mechanism A, a decoking mechanism B and a combing machine connected in sequence. The opening mechanism includes a primary opening unit a1 and a secondary opening unit a2. The decoking mechanism includes at least three sets of dust cage type decoking units b connected in sequence. In this embodiment, six sets of dust cage type decoking units b are preferably used.

[0033] The feeding machine and the combing machine both use existing technologies, which will not be described in detail in this embodiment.

[0034] As shown in Figure 2, the primary opening unit a1 includes a first feed roller 1, a first licker roller 2 mounted on one side of the first feed roller 1, a chest cylinder 3 mounted on the side of the first licker roller 2 away from the first feed roller 1, two sets of opening roller assemblies spaced apart around the chest cylinder 3, a first transfer roller 4 mounted on the side of the chest cylinder 3 away from the first licker roller 2, a large cylinder 5 mounted on the side of the first transfer roller 4 away from the chest cylinder 3, and three sets of opening roller assemblies mounted around the large cylinder 5. The opening roller assemblies on the chest cylinder 3 and the large cylinder 5 have the same structure, both including a work roller 6 and a stripping roller 7.

[0035] After being fed by the wool feeder and the first feeding roller 1, the cashmere fibers are first pre-carded by the first carding roller 2 to improve the subsequent opening effect. Then, they are opened by the chest cylinder 3, and then transferred to the large cylinder 5 by the first transfer roller 4 for another opening treatment.

[0036] Furthermore, the diameter of the breast cylinder is 500mm, and the diameter of the large cylinder is 700mm.

[0037] As shown in Figure 3, the secondary opening unit a2 includes a second transfer roller 8. A spun cylinder 9 is installed on one side of the second transfer roller 8. The second transfer roller 8 is used to connect the large cylinder 5 and the spun cylinder 9. The interaction between the second transfer roller 8 and the spun cylinder 9 performs an opening process on the cashmere fibers. A doffer 10 is installed on the side of the spun cylinder 9 away from the second transfer roller 8 to transfer the cashmere fibers on the spun cylinder 9 to the doffer 10. A cutter 11 is installed on the side of the doffer 10 away from the spun cylinder 9 to cut the cashmere fibers on the doffer 10. At least two first support rollers 12 are provided below the cutter 11. In this embodiment, two first support rollers are provided. The first support rollers 12 are smooth rollers used to assist in guiding the cut cashmere fibers into the next process.

[0038] Furthermore, the diameter of the coarse cylinder roller is 250mm.

[0039] In this embodiment, the cashmere fibers undergo two opening processes through the primary opening unit a1, and then one opening process through the secondary opening unit a2. Compared with the existing opening mechanism, the opening effect is greatly improved, creating more favorable conditions for subsequent decoction and cashmere retention.

[0040] The top of the doffer 10 is equipped with a doffer cleaning structure, as shown in Figure 4. The doffer cleaning structure includes a cleaning roller shaft 13, the surface of which is provided with several brush bundles. Both ends of the cleaning roller shaft 12 are respectively equipped with seated bearings 14. Each seated bearing 14 is equipped with a U-shaped bracket 15. The specific assembly structure is as follows: the seated bearing 14 is located inside the U-shaped bracket 15. The bottom of the seated bearing 14 is connected to the inner bottom wall of the U-shaped bracket 15 by a spring 16. The left side of the seated bearing 14 is slidably connected to the inner left wall of the U-shaped bracket 15, and the right side of the seated bearing 14 is slidably connected to the inner right wall of the U-shaped bracket 15. The above sliding connection adopts the method of groove and slider. Specifically, a vertical groove (not shown in the figure) is provided on the seated bearing 14, and a slider (not shown in the figure) is provided on the inner wall of the U-shaped bracket 15. The groove and the slider are slidably connected.

[0041] Both U-shaped brackets 15 are fixedly mounted on the secondary opening unit frame, and a pressing assembly is provided above each U-shaped bracket 15. The pressing assembly includes a cam 17, which is rotatably mounted on the secondary opening unit frame via a bearing. The cam 17 is provided with a handle 18 and an L-shaped locking rod 19. In this embodiment, rotating the handle 18 counterclockwise disengages the protrusion of the cam 17 from the top of the bearing 14, and the cleaning roller 13 is pushed upward by the spring 16, causing the brush bundle to disengage from the surface of the doffer 10. Rotating the handle 18 clockwise causes the protrusion of the cam 17 to interfere with the top of the bearing 14 and press the bearing 14 downward, causing the bearing 14 to move downward and compress the spring 16. At the same time, the brush bundle contacts the doffer 10. At this time, the end of the L-shaped locking rod 19 can be locked in the slot provided on the side wall of the U-shaped bracket 15 to prevent the cam 17 from rotating. In this state, rotating the cleaning roller shaft 13 can brush off the lint on the surface of the doffer 10 through the brush bundle.

[0042] This embodiment also provides a pressing assembly with another structure, specifically including a horizontal plate, which is fixedly installed at the top opening of the U-shaped bracket. The horizontal plate is provided with a set screw, which can be turned to move the bearing seat downward.

[0043] In addition, an openable cover 20 is installed on the top of the cleaning roller 13, which can be opened to maintain and clean the cleaning roller 13 when the machine is stopped.

[0044] As shown in Figure 5, the dust cage type decoupling unit b includes a second idler roller 21, which is a smooth roller. The second idler roller 21 is connected to the first idler roller 12. Specifically, the two first idler rollers 12 in the secondary opening unit a2 and the second idler roller 21 in the adjacent dust cage type decoupling unit form a V-shaped structure to better assist fiber transfer. A second feed roller 22 is installed on one side of the second idler roller 21. A second licker-in roller 23 is installed on the side of the second feed roller 22 away from the second idler roller 21. A dust cage 24 is installed on the side of the second licker-in roller 23 away from the second feed roller 22. A dust cage cleaning roller 25 is installed on the side of the dust cage 24 away from the second licker-in roller 23 and at a lower position.

[0045] The feeding plate 26 is located above the second feeding roller 22. The inner side of the feeding plate 26 is arc-shaped and is fitted with the second feeding roller 22 with a gap. The cashmere fibers are fed from between the second feeding roller 22 and the feeding plate 26 in a forward feeding manner, and then continue forward from the bottom of the second licker-in roller 23. The second feeding roller 22 and the second licker-in roller 23 rotate in opposite directions. Compared with the existing feeding structure, the fiber transfer angle is smoother, which can reduce fiber breakage caused by reverse feeding.

[0046] The specific structure and working principle of the dust cage 24 are based on existing technology and will not be described in detail here.

[0047] As shown in Figure 6, the surface of the dust cage cleaning roller 25 is provided with elastic paddles 27 along the axial direction. The specific material is rubber. There are at least two elastic paddles 27, which are arranged at intervals along the circumference. When the dust cage cleaning roller 25 is rotated, the outer edge of the elastic paddles 27 contacts the dust cage 24 and is used to peel off the lint attached to the surface of the dust cage 24.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
