Description

Technical Field

[0001] The present invention relates to the technical field of carding machines, and particularly to a movable flat and a carding machine. Background Art

[0002] The function of the movable flat of a carding machine is mainly to comb, remove impurities, mix and remove most of the cotton knots, impurities and short fibers from the loosened loose fibers during the cleaning process. The gauge between the movable flat and the cylinder card clothing of the carding machine is very important for the quality of carding. In the existing production process, when we are doing small-batch production, making samples for customers or conducting production tests on a new batch of raw materials, a small carding machine is needed. The small carding machine also has structures such as a movable flat, a cylinder, and a licker-in. However, since the small carding machine is used for small-batch trial production and often needs to test various raw materials, the small carding machine needs to be frequently reconfigured. And reconfiguring the carding machine is very troublesome. Because the fiber thicknesses of various raw materials are different and the qualities of the raw materials are also different, it is necessary to adjust the lengths and densities of the needle teeth on the structures such as the movable flat, the cylinder, and the licker-in. Therefore, it is necessary to replace parts, especially the replacement of the movable flat. Because there are many strips of the movable flat, each strip of the movable flat needs to be disassembled and replaced, and sometimes even the card clothing on the flat needs to be replaced one by one.

[0003] Therefore, we need a carding machine that is convenient to reconfigure, and a movable flat that can adjust the density arrangement of the needle teeth and the carding length on the movable flat according to the type of raw material and the fiber thickness. In this way, it is not necessary to disassemble and replace each strip of the movable flat during reconfiguration, which can save a lot of time. Summary of the Invention

[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and the accompanying drawings.

[0028] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0029] Referring to Figures 1 - 10 , this embodiment provides a carding machine, including a movable flat 1, which is also connected to other structures in the carding machine. The movable flat 1 includes a keel 11, and the keel 11 plays a role in fixing and supporting the movable flat. A bottom plate 12 is provided at the bottom of the keel 11, and a receiving groove is formed at the bottom of the bottom plate 12. As Figure 2 shown, a horizontal slot is formed at the bottom of the bottom plate 12, and two extended clamping edges are formed on the left and right sides at the bottom of the bottom plate 12. A connecting member 13 is provided on the side of the bottom plate 12. Since there are multiple movable flats connected in a chain structure on the carding machine, the connecting member 13 here is a connecting and driving structure that needs to be connected in a chain; and, A cylinder 4 provided at the bottom of the movable flat 1, a licker-in 5 is provided on the side of the cylinder 4, and a doffer 6 is provided on the side of the cylinder 4 away from the licker-in 5. After the raw material is preliminarily opened and cleaned, it is fed into the carding machine by a feed roller. The feed roller rotates to evenly feed the fiber layer of the cotton bale into the area of the licker-in 5, and the surface of the licker-in 5 is equipped with card clothing.

[0030] A carding member 2 provided inside the keel 11, the carding member 2 includes a needle structure capable of adjusting the arrangement and carding depth. When the carding member 2 combs the raw material, it refines and separates the fibers, removes impurities such as cotton seeds and stone particles, and at the same time separates some short fibers that do not meet the production requirements, and, An adjusting member 3 provided on the side of the keel 11, the adjusting member 3 is connected to the carding member 2. When a changeover is required, the carding member 2 can be adjusted through the adjusting member 3, and the arrangement of the needles and the protruding length of the needles can be adjusted according to the type of raw material.

[0031] Further, a heat insulation layer 14 is provided at the bottom of the bottom plate 12, a contact plate 15 is provided at the bottom of the heat insulation layer 14, a needle outlet groove 16 is formed in the outer wall of the contact plate 15, the needle outlet groove 16 penetrates through the contact plate 15, and the needle outlet groove 16 is also formed in the outer wall of the heat insulation layer 14 and penetrates through the heat insulation layer 14. During the carding process, if the heat generated by the needles is directly conducted to the keel 11, it may cause the keel 11 to be deformed by heat, resulting in a decrease in carding quality.

[0032] Usage process: When carding raw material fibers, after preliminary loosening and impurity removal, the raw materials are fed into the carding machine by the feed roller. The feed roller rotates to evenly feed the fiber layer of the cotton bale into the area of the licker-in 5. The surface of the licker-in 5 is equipped with card clothing, and the card clothing performs preliminary loosening and carding on the fibers. The cylinder 4 performs more meticulous carding on the fibers. The movable flat 1 reciprocates on the surface of the cylinder 4 and closely cooperates with the card clothing of the cylinder 4 to perform meticulous carding on the fibers and can further remove fine impurities in the fibers. The doffer 6 condenses the fiber layer into a fiber web with a certain thickness and uniformity. The fiber web is then stripped off by the stripping device and enters the subsequent forming process. The heat insulation layer 14 can prevent the heat of the needles from being transferred to the keel 11, thereby preventing the keel 11 from expanding and deforming due to heat. When the carding raw materials are changed, such as changing from coarser fibers to finer fibers, the card needle member 2 can be adjusted by the adjusting member 3, and the arrangement of the needles and the protruding length of the needles can be adjusted according to the raw materials.

[0033] Example 2, referring to Figures 1 - 10 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment specifically illustrates the structure of the card needle member 2 and explains how to adjust the arrangement and protruding length of the needles. Among them, the card needle member 2 includes a cage structure 21, and the number of cage structures 21 is multiple. A carding needle structure 22 is arranged inside the cage structure 21. In the cage structure 21, the number of carding needle structures 22 is multiple. During the carding process, the cage structure 21 will always ensure that the carding needles are in a vertical state of carding the raw materials. A sliding frame structure 23 is arranged on the side of the cage structure 21, and the sliding frame structure 23 is connected to the carding needle structure 22. As Figure 4 shown, the sliding frame structure 23 can slide up and down on the outer wall of the cage structure 21, and at the same time drive the carding needle structure 22 to rise or fall together, so as to adjust the protruding length of the needles.

[0034] Further, the cage structure 21 includes a fixing frame 211 arranged on the top of the bottom plate 12. The bottom of the fixing frame 211 is fixedly connected to the bottom plate 12. A sliding groove 212 is formed on the side of the fixing frame 211. The number of fixing frames 211 is multiple, and multiple sliding grooves 212 are formed on the same fixing frame 211. As Figure 4As shown, preferably, the angles of the sliding grooves 212 formed on each fixing frame 211 are not necessarily the same. In the figure, the sliding grooves 212 formed on the first row of fixing frames 211 facing the audience are vertical, and the sliding grooves 212 formed on the second row of fixing frames 211 are inclined. It can be set that the sliding grooves 212 of the odd rows are vertical and the sliding grooves 212 of the even rows are inclined, and the carding needle structures 22 of the odd rows and the carding needle structures 22 of the even rows are arranged staggeredly in the direction towards the audience. Thus, the arrangement of the needles is as Figure 7 shown. At this time, as shown in the figure, the density of the needles in the advancing direction of the fibers to be carded in the moving direction is relatively dense. If the holding frame structure 21 moves downward to drive the carding needle structure 22 to move downward, the carding needles of the odd rows will not change in the horizontal position, while the carding needles of the even rows will move horizontally towards the carding needles of the odd rows under the action of the inclined sliding grooves 212 until the carding needle structures 22 on the even-row fixing frames 211 and the carding needle structures 22 on the odd-row fixing frames 211 completely coincide horizontally. At this time, the arrangement of the needles will be as Figure 8 shown. The density of the needles in the advancing direction of the fibers to be carded becomes relatively loose. Of course, the above situation is on the premise that the inclination directions of all the sliding grooves 212 of the even rows are set to be the same.

[0035] Furthermore, a partition plate 213 is provided on the side surface of the fixing frame 211. A longitudinal sliding groove 214 is formed on the side of the fixing frame 211 away from the partition plate 213. The partition plate 213 is fixedly connected to the fixing frame 211. There is an accommodating space between the partition plate 213 and the fixing frame 211. The carding needle structure 22 includes a carding needle body 221 provided on the side surface of the fixing frame 211. The carding needle body 221 is arranged between the fixing frame 211 and the partition plate 213. A slider 222 is provided at the top of the carding needle body 221. The slider 222 is arranged inside the sliding groove 212. The slider 222 can slide up and down on the sliding groove 212, driving the carding needle body 221 to rise or fall, as Figure 3 shown. The carding needle body 221 extending out under the contact plate 15 is the needle segment for carding the raw material. When the carding needle body 221 rises, the carding needle body 221 extending out under the contact plate 15 becomes shorter, and the length of the needles for carding the raw material naturally becomes shorter. On the contrary, when the carding needle body 221 descends, the length of the needles for carding the raw material will become longer, that is, the depth of the needles extending into the raw material becomes deeper. A holding sleeve 223 is sleeved on the outer wall of the carding needle body 221. A protection plate 224 is provided at the bottom of the holding sleeve 223. The length of the protection plate 224 is greater than the length of the needle outlet groove 16, as Figure 4As shown, the holding sleeve 223 is sleeved on the outer wall of the carding needle body 221. The holding sleeve 223 is fixedly connected to the protection plate 224. The protection plate 224 can slide on the bottom plate 12. When the carding needle body 221 rises or falls on the bottom plate 12, or undergoes lateral sliding, the holding sleeve 223 will always maintain the vertical carding state of the carding needle body 221.

[0036] Furthermore, the sliding frame structure 23 includes a connecting slide plate 231 disposed on the side of the fixed frame 211. Guide rods 232 are provided on the side of the connecting slide plate 231. The number of guide rods 232 is multiple. Transverse chutes 233 are formed inside the guide rods 232. One end of the slider 222 away from the fixed frame 211 is disposed inside the transverse chute 233. Thus, when the connecting slide plate 231 rises or falls, it will drive the guide rods 232 to rise or fall together, and the slider 222 will also drive the carding needle body 221 and the guide rods 232 to rise or fall together. As Figure 5 shown, the connecting slide plate 231 is connected to the slider 222 in each carding needle structure 22 through the guide rods 232. When the connecting slide plate 231 rises, it will drive all the carding needle bodies 221 to rise, shortening the length of the needles during carding. When the connecting slide plate 231 descends, it will drive all the carding needle bodies 221 to descend, lengthening the length of the needles during carding, that is, the carding depth. A clamping plate 234 is provided on the side of the guide rod 232. One end of the clamping plate 234 away from the connecting slide plate 231 is disposed inside the longitudinal chute 214. As Figure 5 shown, the clamping plate 234 can slide up and down inside the longitudinal chute 214.

[0037] During use: When conducting trial production or raw material tests using a small carding machine, the raw materials that are frequently replaced may include fine fibers such as silk. Such finer fibers require shorter needles to protect the fibers, and at the same time, the carding density of the needles needs to be denser to ensure the carding quality. Therefore, at this time, the connecting slide plate 231 is at a relatively high position on the fixed frame 211, and the length of the carding needle body 221 extending out to contact the bottom of the plate 15 is shorter. At this time, the carding needle bodies 221 on the odd-numbered rows of the fixed frame 211 and the carding needle bodies 221 on the even-numbered rows of the fixed frame 211 are arranged in an interleaved manner. As Figure 7 shown, the density of the comb teeth of the raw materials in the forward direction is denser. When coarser fibers such as hemp need to be carded, longer needles with a smaller density are required. Thus, the connecting slide plate 231 descends, and the carding needles on the even-numbered rows will move laterally towards the carding needles on the odd-numbered rows under the action of the inclined sliding grooves 212 until the carding needle structures 22 on the even-numbered rows of the fixed frame 211 and the carding needle structures 22 on the odd-numbered rows of the fixed frame 211 completely overlap laterally. At this time, the arrangement of the needles will be as Figure 8As shown, at this time, the length of the carding needle body 221 extending out to contact the plate 15 becomes longer, and the density of the comb teeth of the raw material in the advancing direction also becomes smaller. The present invention can adjust the arrangement and length of the carding needles according to different raw materials, and can simultaneously adjust the length and relative density, making the mold change convenient.

[0038] Embodiment 3, refer to Figures 1 - 10 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment illustrates how to use the adjusting member 3 to arrange and specifically adjust the carding needle member 2. Specifically, the adjusting member 3 includes a housing 31 arranged above the bottom plate 12. A guiding sliding plate 32 is arranged inside the housing 31. A first elastic member 33 is arranged on the side of the guiding sliding plate 32. One end of the first elastic member 33 away from the guiding sliding plate 32 is connected to the inner wall of the housing 31. The first elastic member 33 is in a compressed state. A guiding groove 34 is formed on the outer wall of the guiding sliding plate 32, and a pressing structure 35 is arranged on the side of the guiding sliding plate 32.

[0039] Furthermore, the pressing structure 35 includes a button 351 arranged on the top of the housing 31. A connecting rod 352 is arranged at the bottom of the button 351. One end of the connecting rod 352 away from the guiding sliding plate 32 is connected to the connecting sliding plate 231. Pressing the button 351 will drive the connecting rod 352 and the connecting sliding plate 231 to slide downward together. One end of the connecting rod 352 away from the connecting sliding plate 231 extends into the guiding groove 34. A pressing plate 353 is arranged on the side of the connecting rod 352. A second elastic member 354 is arranged at the bottom of the pressing plate 353. The second elastic member 354 is in a compressed state, and the bottom of the second elastic member 354 is connected to the bottom plate 12.

[0040] Furthermore, the connecting rod 352 connected to the slider 222 will slide in the guiding groove 34. The guiding groove 34 is set in multiple sections to cope with several different types of raw materials, specifically: finer fibers, coarser fibers, and coarser fibers containing more impurities. Finer fibers require carding needles with a denser arrangement and a shorter length; coarser fibers require carding needles with a looser arrangement and a longer length; while coarser fibers containing more impurities require carding needles with a denser arrangement and a longer length to ensure the carding effect, such as Figure 6As shown, the guiding groove 34 includes a first inclined groove 341 provided on the outer wall of the guiding slide plate 32. A coarse fiber holding groove 342 is provided at the bottom of the first inclined groove 341. The coarse fiber holding groove 342 is horizontally arranged. A second inclined groove 343 is provided at the bottom of the coarse fiber holding groove 342. A multi-impurity holding groove 344 is provided at the bottom of the second inclined groove 343. The multi-impurity holding groove 344 is horizontally arranged. A third inclined groove 345 is formed at the bottom of the multi-impurity holding groove 344. A reset arc groove 346 is provided at the bottom of the third inclined groove 345. The top of the reset arc groove 346 is connected to the top of the first inclined groove 341. When the connecting rod 352 is at the top of the first inclined groove 341 in the figure, at this time, the connecting slide plate 231 is at a relatively high position on the fixed frame 211, and the length of the needle extending out of the bottom of the contact plate 15 is short. The overall arrangement of the needles is as Figure 7 shown. At this time, the needles are arranged densely and the carding length is short. At this time, it is suitable for carding finer fibers. When changing to coarser fibers, press the button 351 downward, driving the connecting rod 352 to slide downward along the first inclined groove 341. At this time, the guiding slide plate 32 will slide in the direction of the second elastic member 354, and the second elastic member 354 is compressed. When the connecting rod 352 contacts the coarse fiber holding groove 342, at this time, the connecting slide plate 231 drives the carding needle body 221 to extend downward by a certain distance, and the overall arrangement of the needles is as Figure 8 shown. At this time, the connecting rod 352 is in contact with the coarse fiber holding groove 342. Under the action of the second elastic member 354, the guiding slide plate 32 will slide a certain distance in the direction away from the second elastic member 354 until the connecting rod 352 is stuck at the connection between the second inclined groove 343 and the coarse fiber holding groove 342. This is the state required for carding coarser fibers. When changing to coarser fibers containing more impurities, press the button 351 again. The button 351 drives the connecting rod 352 to slide downward along the second inclined groove 343 together. When the connecting rod 352 contacts the multi-impurity holding groove 344, under the action of the second elastic member 354, the guiding slide plate 32 will rebound a certain distance, and the connecting rod 352 is stuck at the connection between the third inclined groove 345 and the multi-impurity holding groove 344. At this time, the carding needle body 221 has dropped another distance, and since the slider 222 will continue to slide downward in the sliding groove 212, the even-numbered carding needle bodies 221 will move away from the odd-numbered carding needle bodies 221 in the horizontal direction under the action of the sliding groove 212, and finally form as Figure 9In the shown arrangement, the carding needle bodies 221 return to a relatively dense arrangement state again. At this time, the carding needle bodies 221 extend deeper into the contact plate 15, which is suitable for carding coarser fibers containing more impurities. After the carding is completed, press the button 351 again, and the connecting rod 352 will continue to slide downward along the third inclined groove 345 until the connecting rod 352 contacts the reset arc groove 346. At this time, under the action of the first elastic member 33, the button 351 will rise and reset under the upward elastic force, and at the same time, under the action of the second elastic member 354, the guiding slide plate 32 will also slide and reset in the direction away from the second elastic member 354 until the connecting rod 352 returns to the uppermost position of the guiding groove 34. At this time, the connecting slide plate 231 also returns to the initial highest point, and the overall arrangement of the needles also returns to the state as Figure 7 shown.

[0041] Usage process: When the button 351 of the present invention is at the uppermost position, it is suitable for carding finer fibers. When coarser fibers are used, press the button 351 once to adjust the arrangement and extension length of the needles, making the needles denser in the movement direction of the fibers and increasing the carding length of the needles. When coarser fibers containing more impurities are used, press the button 351 again to make corresponding adjustments to the carding needle bodies 221 to make them suitable for the new raw materials. When finer fibers are used again, pressing the button 351 again can make the button 351 return to the uppermost position, and the arrangement of the needles also returns to the initial state.

[0042] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
