Description

Technical Field

[0001] The present invention relates to the technical field of cotton carding machines, in particular to a movable cover plate and a cotton carding machine. Background Art

[0002] The main function of the movable cover of the carding machine is to comb, remove impurities, mix and remove most of the cotton knots, impurities and short fibers during the cleaning process. The distance between the movable cover and the cylinder card clothing of the carding machine is very important for the quality of carding. In the existing production process, we need to use a small carding machine when we are doing small batch production, making samples for customers or doing production tests on a new batch of raw materials. The small carding machine also has structures such as movable covers, cylinders, and taker-in rollers. However, since small carding machines are used for small batch trial production and often need to test a variety of raw materials, small carding machines need to be frequently changed, and changing the carding machine is very troublesome because the fiber thickness of a variety of raw materials is different and the quality of the raw materials is also different. Therefore, the length and density of the needle teeth on the movable cover, cylinder, taker-in roller and other structures need to be adjusted. Therefore, parts need to be replaced, especially the replacement of the movable cover, because there are many movable covers, and each movable cover needs to be disassembled and replaced, and sometimes even the card clothing on the cover needs to be replaced one by one.

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0031] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled 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 rather as the meanings of the terms and the overall description of the present invention.

[0032] Reference Figures 1 to 10 The present embodiment provides a carding machine, including a movable cover 1, which is also connected to other structures in the carding machine. The movable cover 1 includes a keel 11, which plays a role in fixing and supporting the movable cover. A bottom plate 12 is provided at the bottom of the keel 11, and a receiving groove is provided at the bottom of the bottom plate 12. Figure 2 As shown, a horizontal groove is formed at the bottom of the bottom plate 12, and two extending clamping edges are formed on the left and right sides of the bottom of the bottom plate 12. A connecting member 13 is provided on the side of the bottom plate 12. Because there are multiple movable cover plates connected to form a chain structure on the carding machine, the connecting member 13 here is a connecting transmission structure that needs to be chain-connected; and,

[0033] A cylinder 4 is arranged at the bottom of the movable cover 1, and a licker-in roller 5 is arranged on the side of the cylinder 4. A doffer 6 is arranged on the side of the cylinder 4 away from the licker-in roller 5. After preliminary opening and impurity removal, the raw material is fed into the carding machine through the cotton feeding roller. The cotton feeding roller rotates to evenly feed the fiber layer of the cotton roll into the licker-in roller 5 area. The surface of the licker-in roller 5 is equipped with a card cloth.

[0034] The combing needle component 2 is arranged inside the keel 11. The combing needle component 2 includes a needle structure that can adjust the arrangement and combing depth. When combing the raw materials, the combing needle component 2 refines and separates the fibers, removes impurities such as cotton seeds and stones, and separates some short fibers that do not meet production requirements, and

[0035] An adjusting member 3 is provided on the side of the keel 11 and is connected to the combing needle member 2. When a change of shape is required, the combing needle member 2 can be adjusted by the adjusting member 3 to adjust the arrangement of the needles and the extension length of the needles according to the type of raw material.

[0036] Furthermore, a heat insulation layer 14 is provided at the bottom of the base plate 12, and a contact plate 15 is provided at the bottom of the heat insulation layer 14. A needle outlet groove 16 is provided on the outer wall of the contact plate 15, and the needle outlet groove 16 passes through the contact plate 15. A needle outlet groove 16 is also provided on the outer wall of the heat insulation layer 14, and the needle outlet groove 16 passes through the heat insulation layer 14. If the heat generated by the needle during the combing process is directly conducted to the keel 11, the keel 11 may be deformed by heat, resulting in a decrease in the combing quality.

[0037] Usage process: When combing the raw fiber, the raw material is fed into the carding machine through the cotton feeding roller after preliminary opening and impurity removal. The cotton feeding roller rotates to feed the fiber layer of the cotton roll evenly into the licker-in roller 5 area. The surface of the licker-in roller 5 is equipped with a needle cloth, which performs preliminary opening and combing of the fibers. The cylinder 4 combs the fibers more finely. The movable cover 1 reciprocates on the surface of the cylinder 4, closely cooperating with the cylinder 4 needle cloth to comb the fibers finely and 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 needle from being transferred to the keel 11, thereby preventing the keel 11 from expanding and deforming due to heat. When the carding raw material is replaced, such as replacing thicker fibers with thinner fibers, the combing needle component 2 can be adjusted by the adjusting component 3 to adjust the arrangement of the needles and the extension length of the needles according to the raw material.

[0038] Example 2, reference Figures 1 to 10 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment specifically describes the structure of the combing needle component 2 and explains how to adjust the arrangement and extension length of the needles. The combing needle component 2 includes a retaining frame structure 21. The number of retaining frame structures 21 is multiple. A combing needle structure 22 is arranged inside the retaining frame structure 21. In the retaining frame structure 21, the number of combing needle structures 22 is multiple. During the combing process, the retaining frame structure 21 will always ensure that the combing needles are in a vertical state of combing the raw materials. A sliding frame structure 23 is provided on the side of the retaining frame structure 21. The sliding frame structure 23 is connected to the combing needle structure 22, as shown in FIG. Figure 4 As shown, the sliding frame structure 23 can slide up and down the outer wall of the retaining frame structure 21, and at the same time, it can move up or down with the combing needle structure 22, thereby adjusting the extension length of the needle.

[0039] Furthermore, the retaining frame structure 21 includes a fixing frame 211 provided on the top of the bottom plate 12, the bottom of the fixing frame 211 is fixedly connected to the bottom plate 12, and a sliding groove 212 is provided on the side of the fixing frame 211. There are multiple fixing frames 211, and multiple sliding grooves 212 are provided on the same fixing frame 211. Figure 4As shown, preferably, the angles of the sliding grooves 212 opened on each fixing frame 211 are not necessarily the same. In the figure, the sliding grooves 212 opened on the first row of fixing frames 211 facing the audience are vertical, and the sliding grooves 212 opened on the second row of fixing frames 211 are oblique. It can be set that the sliding grooves 212 in odd rows are vertical, and the sliding grooves 212 in even rows are oblique, and the combing needle structures 22 in odd rows and the combing needle structures 22 in even rows are staggered in the direction toward the audience, so the arrangement of the needles is as follows Figure 7 As shown, at this time, the density of the needles in the forward direction of the fibers to be combed in the moving direction in the figure is relatively dense, and if the retaining frame structure 21 moves downward to drive the combing needle structure 22 to move downward, the combing needles in the odd rows will not change in the lateral position, while the combing needles in the even rows will move laterally toward the combing needles in the odd rows under the action of the oblique sliding grooves 212, until the combing needle structures 22 on the even rows of fixed frames 211 and the combing needle structures 22 on the odd rows of fixed frames 211 completely overlap in the lateral direction. At this time, the arrangement of the needles will be as follows Figure 8 As shown, the density of the needles of the fibers to be combed becomes looser in the forward direction. Of course, the above situation is based on the premise that the inclination directions of the sliding grooves 212 of all even-numbered rows are set to be consistent.

[0040] Furthermore, a partition 213 is provided on the side of the fixing frame 211, and a longitudinal slide groove 214 is opened on the side of the fixing frame 211 away from the partition 213. The partition 213 is fixedly connected to the fixing frame 211, and there is an accommodating space between the partition 213 and the fixing frame 211. The combing needle structure 22 includes a combing needle body 221 arranged on the side of the fixing frame 211, and the combing needle body 221 is arranged between the fixing frame 211 and the partition 213. A slider 222 is provided on the top of the combing needle body 221, and the slider 222 is arranged inside the sliding groove 212. The slider 222 can slide up and down the sliding groove 212, and the combing needle body 221 rises or falls, as shown in FIG. Figure 3 As shown, the combing needle body 221 extending from under the contact plate 15 is a needle segment for combing the raw material. When the combing needle body 221 rises, the combing needle body 221 extending from under the contact plate 15 becomes shorter, and the length of the needle for combing the raw material naturally becomes shorter. Conversely, when the combing needle body 221 descends, the length of the needle for combing the raw material will become longer, that is, the depth of the needle inserted into the raw material becomes deeper. The outer wall of the combing needle body 221 is provided with a retaining sleeve 223, and the bottom of the retaining sleeve 223 is provided with a protective plate 224. The length of the protective plate 224 is greater than the length of the needle outlet groove 16, as shown in FIG. Figure 4As shown, the retaining sleeve 223 is sleeved on the outer wall of the combing needle body 221, and the retaining sleeve 223 is fixedly connected to the protective plate 224. The protective plate 224 can slide on the base plate 12. When the combing needle body 221 rises or falls on the base plate 12, or slides horizontally, the retaining sleeve 223 will always maintain the vertical combing state of the combing needle body 221.

[0041] Furthermore, the sliding frame structure 23 includes a connecting slide 231 arranged on the side of the fixed frame 211, and a guide rod 232 is arranged on the side of the connecting slide 231. There are multiple guide rods 232, and a horizontal slide groove 233 is opened inside the guide rod 232. The end of the slider 222 away from the fixed frame 211 is set inside the horizontal slide groove 233, so that the rising or falling of the connecting slide 231 will drive the guide rod 232 to rise or fall together, and the slider 222 will also bring the cotton combing needle body 221 and the guide rod 232 to rise or fall together. Figure 5 As shown, the connecting slide 231 is connected to the slider 222 in each combing needle structure 22 through the guide rod 232. When the connecting slide 231 rises, it will drive all the combing needle bodies 221 to rise, shortening the length of the combing needles. When the connecting slide 231 falls, it will drive all the combing needle bodies 221 to fall, lengthening the length of the combing needles, that is, the combing depth. A gusset plate 234 is provided on the side of the guide rod 232. The end of the gusset plate 234 away from the connecting slide 231 is provided inside the longitudinal slide groove 214, as shown in FIG. Figure 5 As shown, the pinch plate 234 can slide up and down in the longitudinal slide groove 214 .

[0042] Usage process: When using a small carding machine for trial production or raw material testing, the frequently replaced raw materials may contain fine fibers such as silk. Such fine fibers require shorter needles to protect the fibers. At the same time, the combing density of the needles needs to be denser to ensure the combing quality. Therefore, at this time, the connecting slide 231 is at a higher position on the fixed frame 211, and the length of the carding needle body 221 extending from the bottom of the contact plate 15 is shorter. At this time, the carding needle bodies 221 on the odd-numbered rows of fixed frames 211 are staggered with the carding needle bodies 221 on the even-numbered rows of fixed frames 211, as shown in FIG. Figure 7 As shown in FIG, the density of the comb teeth in the forward direction of the raw material is relatively dense, and when it is necessary to comb thicker fibers such as flax, the comb needles need to be longer and have a smaller density, so the connecting slide 231 descends, and the combing needles in the even-numbered rows move laterally toward the combing needles in the odd-numbered rows under the action of the oblique sliding groove 212, until the combing needle structures 22 on the even-numbered rows of the fixing frame 211 and the combing needle structures 22 on the odd-numbered rows of the fixing frame 211 completely overlap in the laterally. At this time, the arrangement of the needles will be as shown in FIG. Figure 8As shown, at this time, the length of the combing needle body 221 extending from the contact plate 15 becomes longer, and the density of the comb teeth in the forward direction of the raw material also becomes smaller. The present invention can adjust the arrangement and length of the combing needles according to different raw materials, and can adjust the length and relative density at the same time, making the change of type convenient.

[0043] Example 3, reference Figures 1 to 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 pre-arrange and specifically adjust the combing needle member 2. Specifically, the adjusting member 3 includes a shell 31 arranged above the bottom plate 12, and a guide slide 32 is provided inside the shell 31. A first elastic member 33 is provided on the side of the guide slide 32. The end of the first elastic member 33 away from the guide slide 32 is connected to the inner wall of the shell 31. The first elastic member 33 is in a compressed state. A guide groove 34 is provided on the outer wall of the guide slide 32, and a pressing structure 35 is provided on the side of the guide slide 32.

[0044] Furthermore, the pressing structure 35 includes a button 351 arranged on the top of the shell 31, and a connecting rod 352 is provided at the bottom of the button 351. The end of the connecting rod 352 away from the guide slide 32 is connected to the connecting slide 231. Pressing the button 351 will drive the connecting rod 352 and the connecting slide 231 to slide downward together. The end of the connecting rod 352 away from the connecting slide 231 extends to the inside of the guide groove 34. A pressure plate 353 is provided on the side of the connecting rod 352, and a second elastic member 354 is provided at the bottom of the pressure 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.

[0045] Furthermore, the connecting rod 352 connected to the slider 222 will slide in the guide groove 34. The guide groove 34 is set to multiple sections in order to cope with several different types of raw materials, specifically: finer fibers, thicker fibers and thicker fibers with more impurities. The finer fibers require denser and shorter combing needles; the thicker fibers require looser and longer combing needles; and the thicker fibers with more impurities require denser and longer combing needles to ensure the combing effect. Figure 6As shown, the guide groove 34 includes a first inclined groove 341 arranged on the outer wall of the guide slide 32, and a coarse fiber holding groove 342 is provided at the bottom of the first inclined groove 341, and the coarse fiber holding groove 342 is arranged horizontally. A second inclined groove 343 is provided at the bottom of the coarse fiber holding groove 342, and a multi-impurity holding groove 344 is provided at the bottom of the second inclined groove 343. The multi-impurity holding groove 344 is arranged horizontally, and a third inclined groove 345 is provided 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, and 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, the connecting slide 231 is in a higher position on the fixing frame 211, and the length of the needle extending out of the bottom of the contact plate 15 is shorter. The overall arrangement of the needle is as shown in FIG. Figure 7 As shown, at this time, the needles are arranged more densely and the combing length is shorter, which is suitable for combing finer fibers. When switching to thicker fibers, the button 351 is pressed downward to drive the connecting rod 352 to slide downward along the first inclined groove 341. At this time, the guide slide 32 will slide in the direction of the second elastic member 354. The second elastic member 354 is compressed. When the connecting rod 352 contacts the coarse fiber holding groove 342, the connecting slide 231 drives the combing needle body 221 to extend downward for a section, and the overall arrangement of the needles is as shown in FIG. Figure 8 As shown, at this time, the connecting rod 352 is in contact with the coarse fiber holding groove 342, and under the action of the second elastic member 354, the guide slide 32 will slide a distance 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 combing thicker fibers. When switching to thicker fibers containing more impurities, press the button 351 again, and the button 351 will slide down along the second inclined groove 343 with the connecting rod 352. When the connecting rod 352 contacts the multi-impurity holding groove 344, the guide slide 32 will rebound a distance under the action of the second elastic member 354, 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 combing needle body 221 drops a distance again, and because the slider 222 continues to slide downward in the sliding groove 212, the combing needle bodies 221 in the even-numbered rows will move away from the combing needle bodies 221 in the odd-numbered rows in the horizontal direction under the action of the sliding groove 212, and finally form a Figure 9As shown in the arrangement, the combing needle body 221 has returned to a relatively dense arrangement state. At this time, the combing needle body 221 extends deeper from the contact plate 15, which is suitable for combing thicker fibers with more impurities. After the combing 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 due to the upward elastic force. At the same time, under the action of the second elastic member 354, the guide slide 32 will also slide and reset in the direction away from the second elastic member 354 until the connecting rod 352 returns to the top of the guide groove 34. At this time, the connecting slide 231 has also returned to its original higher point, and the overall arrangement of the needles has also returned to as shown. Figure 7 The situation shown.

[0046] Usage process: When the button 351 of the present invention is at the top, it can be used for combing thinner fibers. When it is changed to thicker fibers, pressing the button 351 can adjust the arrangement and extension length of the needles, so that the needles become transported in the movement direction of the fibers and the combing length of the needles becomes longer. When it is changed to thicker fibers containing more impurities, pressing the button 351 again can make corresponding adjustments to the combing needle body 221 to make it suitable for the new raw materials. When it is changed to thinner fibers again, pressing it again can make the button 351 return to the top and the arrangement of the needles return to the initial state.

[0047] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
