Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a novel multifunctional cylinder and a straight combing machine using the cylinder. Background Art

[0002] Combing is the abbreviation of combing engineering or combing process, which refers to the further fine combing on the basis of the full combing of the fiber by the combing system. The tasks and purposes of combing are as follows: 1. Remove short fibers that do not meet the requirements of combed products; 2. Comb the fibers and improve their parallel straightness; 3. Remove various impurities in the fibers; 4. Improve the uniformity of combing. In the current textile industry, straight combing machines are usually used for combing.

[0003] The combing work of the straight combing machine mainly includes the following steps: first, the feeding mechanism feeds the fiber into the clamping mechanism, the clamping mechanism clamps the fiber to fix it and then moves forward, so that the longest fiber outside the jaws enters the stripping and separation mechanism, and then the clamping mechanism releases the clamped fiber and withdraws it backward. At this time, the combing needles fixed on the cylinder below the jaws rotate and insert into the fiber bundle at the jaws to comb the fibers and remove short fibers and debris in the fiber bundle. The cotton drop rate is closely related to the arrangement of the combing needles on the cylinder and other properties. Usually, the larger the area of ​​the combing needles on the cylinder and the denser the arrangement, the higher the cotton drop rate. The cotton drop rate refers to the ratio of the weight of the cotton drop to the weight of the fed raw material. The more cotton drop, the greater the amount of cotton used, the higher the relative cost, but the higher the yarn quality; conversely, the less cotton drop, the smaller the amount of cotton used, the lower the relative cost, but the worse the yarn quality. Therefore, in the combing stage, for the balance between cost and yarn quality, the cotton drop rate is generally maintained at 15%.

[0004] At present, most of the combing needles on the market are fixed, that is, the number, density and arrangement spacing of the combing needles on a cylinder are fixed, that is, a cylinder can usually only be used to comb one type of fiber. However, in the actual production process, there are many types of cotton, and the lengths of different cotton fibers are usually different. Using the same cylinder to comb cotton fibers of different lengths will lead to huge fluctuations in the cotton drop rate, and the production cost and yarn quality will also be greatly affected. In addition, the fixed combing needles do not have any buffering ability. Once they touch the harder debris in the fiber bundle, they are prone to wear and tear. Summary of the invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides a novel multifunctional cylinder and a straight combing machine using the same.

[0006] The technical solution of the present invention is as follows:

[0007] A novel multifunctional cylinder comprises a cylinder roller and a plurality of combing modules. The outer surface of the cylinder roller is provided with a plurality of mounting grooves, the mounting grooves are arranged parallel to the axis direction of the cylinder roller, and the combing modules are arranged in the mounting grooves.

[0008] Furthermore, the combing module includes a combing needle unit and a balancing unit, and the combing needle unit includes a combing needle base, the cross-sectional shape of the combing needle base and the shape of the mounting groove are both fan-shaped, and the central angle of the cross-sectional shape of the combing needle base is smaller than the central angle of the cross-sectional shape of the mounting groove, and the lower end of the combing needle base where the center of the circle is located is rotatably connected to the bottom of the mounting groove, and a plurality of combing needles are arranged on its upper side surface. However, when the combing needles are blocked by debris, the combing needle base can swing in the mounting groove in the opposite direction of the rotation of the cylinder roller, and the combing needle base cooperates with the mounting groove to enable the combing needle base to be slidably connected to the corresponding mounting groove. This design can facilitate the replacement of the combing needle base, and the sizes of the combing needles on different types of combing needle bases can be different. The shapes and spacing arrangements are also different. By changing the number of combing needle units installed on the cylinder roller, the area occupied by the combing needles on the surface of the cylinder roller can be changed, so that the cotton drop rate in the combing step is stably maintained at about 15%, and the combing needle base can swing in the installation groove in the opposite direction of the rotation of the cylinder roller, and can perform swing buffering to prevent the combing needles on the combing needle base from being worn and damaged by hard contact with hard debris. An elastic reset part is also provided on the side of the combing needle base away from the rotation direction of the cylinder roller. The combing needle base can squeeze the elastic reset part in the reverse direction when the cylinder roller rotates, and the elastic reset part can push the combing needle base to reset after it swings.

[0009] Furthermore, the balancing unit includes a plurality of balancing bars, the transverse cross-sectional shape of the balancing bars is the same as the transverse cross-sectional shape of the mounting groove, the weight of the balancing bars is the same as the weight of the comb needle base, and the balancing bars are fixedly installed in the mounting groove where the comb needle base is not installed, so as to balance the weight of the comb needle base.

[0010] As described above, a new type of multifunctional cylinder, the combing needle base is composed of a plurality of transversely arranged combing needle blocks, a plurality of combing needles are arranged on the outer surface of the combing needle blocks, and the combing needle base adopts a modular design composed of combing needle blocks, so that each combing needle block can move independently.

[0011] Furthermore, a fixed shaft is provided in the middle of several of the combing needle blocks and passes through the fixed shaft, which is arranged parallel to the axis direction of the cylinder roller, and the combing needle blocks are rotatably connected to the fixed shaft, and the fixed shaft can fix and connect several fixed blocks in series.

[0012] Furthermore, closed cover plates are movably connected at both ends of the cylinder roller, and fixing holes are provided on the closed cover plates at relative positions to the fixed shaft, and the fixing holes can accommodate the two ends of the fixed shaft for insertion and fixing, thereby fixing the two ends of the fixed shaft, and a pulley is provided on the side of the closed cover plate away from the cylinder roller, and the pulley can be driven and connected to the output shaft of the driving motor through a belt.

[0013] Furthermore, a movably connected sealing plate is provided at the opening on the outward side of the mounting groove, the combing needle can extend through the sealing plate, the length of the sealing plate is greater than the length of the mounting groove, and its two ends can extend from both ends of the mounting groove, and a plurality of sealing grooves are provided on the side of the closing cover plate facing the cylinder roller, the shape of the sealing grooves matches the cross-sectional shape of the sealing plate, and the two ends of the sealing plate can be inserted into the sealing grooves for fixation.

[0014] As described above, a new type of multifunctional cylinder, the transverse cross-section of the combing needle block is fan-shaped, and the central angle of the transverse cross-section of the combing needle block is 10-20 degrees smaller than the central angle of the transverse cross-section of the mounting groove, thereby ensuring that there is sufficient space between the combing needle block and the side wall of the mounting groove to allow the combing needle block to perform buffering swing in the mounting groove.

[0015] Furthermore, the elastic return member is a spring sheet fixed on the side of the comb needle block facing the side wall of the installation groove, and the shape of the spring sheet includes an arc. When the spring sheet is compressed and deformed, a reaction force opposite to the swinging direction of the comb needle block is generated, thereby pushing the comb needle block to return to its original default position in the installation groove.

[0016] As described above, in a novel multifunctional cylinder, both ends of the balance bar are provided with raised positioning buttons at relative positions of the fixing holes of the closed cover plate, and the shape of the positioning buttons matches the shape of the fixing holes, so that the closed cover plate can also fix the balance bar installed in the mounting groove.

[0017] Furthermore, the sealing plate installed at the opening of the mounting groove in which the combing base is installed is a first sealing plate, and the first sealing plate is provided with a combing needle hole at a position relative to the combing needle, and the combing needle hole is in the shape of a long strip and can accommodate the combing needle to move therein, and the sealing plate installed at the opening of the mounting groove in which the balancing bar is installed is a second sealing plate, and the second sealing plate can prevent the combed fibers or debris from entering the mounting groove.

[0018] A straight combing machine comprises the novel multifunctional cylinder as described above.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention discloses a novel multifunctional cylinder and a straight combing machine using the same. The cylinder can freely replace and use the combing needle base according to the demand, thereby changing the area occupied by the combing needle on the cylinder roller, so that when combing fiber bundles of different fiber lengths, the cotton drop rate can be kept at 15% as much as possible, ensuring the balance between production cost and yarn quality;

[0021] 2. The present invention relates to a novel multifunctional cylinder and a straight combing machine using the same. The cylinder roller of the cylinder is provided with a plurality of mounting grooves, and a combing needle block with a plurality of combing needles fixed thereon is movably connected in the mounting grooves. When the combing needles touch hard debris, the combing needle blocks can swing independently in the mounting grooves, which effectively buffers the collision between the combing needles and the debris while not affecting the combing of the fiber bundle by the combing needles on other combing needle blocks.

[0031] See also Figure 1-Figure 5A new type of multifunctional cylinder includes a cylinder roller 1 and a plurality of combing modules 2. The outer surface of the cylinder roller 1 is provided with a plurality of mounting grooves 11, and the mounting grooves 11 are arranged parallel to the axis direction of the cylinder roller 1, and the combing modules are arranged in the mounting grooves.

[0032] Furthermore, the combing module 2 includes a combing needle unit 21 and a balancing unit 22. The combing needle unit 21 includes a combing needle base 211. The cross-sectional shape of the combing needle base 211 and the shape of the mounting groove 11 are both fan-shaped, and the center angle of the cross-sectional area of ​​the combing needle base 211 is smaller than the center angle of the cross-sectional area of ​​the mounting groove 11. The lower end of the combing needle base 211 where the center of the circle is located is rotatably connected to the bottom of the mounting groove 11, and a plurality of combing needles 213 are arranged on the upper side surface. When the combing needles 213 touch the debris, When blocked, the combing needle base 211 can swing in the installation groove 11 in the opposite direction of the rotation of the cylinder roller 1. The combing needle base 211 cooperates with the installation groove 11 to enable the combing needle base 211 to be slidably connected in the corresponding installation groove 11. This design can facilitate the replacement of the combing needle base 211. The size, shape and spacing arrangement of the combing needles 213 on the combing needle base 211 of different models of combing needle units 21 are also different. The installation can be selected according to the type of cotton and fiber length required. Different combing needle units 21 can also change the area occupied by the combing needles 213 on the surface of the cylinder roller 1 by changing the number of combing needle units 21 installed on the cylinder roller 1, so that the cotton drop rate in the combing step is stably maintained at about 15%, ensuring the balance between production cost and yarn quality in the cotton textile process. When the combing needles 213 touch harder debris in the fiber bundle during the combing process, the combing needle base 211 can swing in the opposite direction of the rotation of the cylinder roller 1 under the action of resistance to perform buffering, thereby preventing the combing needles 213 on the combing needle base 211 from being worn and damaged by hard contact with hard debris. An elastic reset member is also provided on the side of the combing needle base 211 away from the rotation direction of the cylinder roller 1. After the combing needle base 211 swings, the reset member can generate resistance to the combing needle base 211 through the elasticity generated by being compressed, so that the combing needle base 211 is reset to the default position, thereby not affecting the subsequent combing of the fiber bundle.

[0033] For further information, see Figure 2 and Figure 5 The balancing unit 22 includes a plurality of balancing bars 221, the transverse cross-sectional shape of the balancing bars 221 is the same as the transverse cross-sectional shape of the mounting groove 11, the weight of the balancing bars 221 is the same as the weight of the combing needle base 211, and the balancing bars 221 are fixedly installed in the mounting groove 11 where the combing needle base 211 is not installed, so as to balance the weight of the combing needle base 211, avoid eccentricity of the cylinder roller 1 during rotation, and prevent excessive wear caused by eccentricity.

[0034] See also Figure 4 The combing needle base 211 is composed of a plurality of transversely arranged combing needle blocks 212, and a plurality of combing needles 213 are arranged on the outer surface of the combing needle block 212. The combing needle base 211 adopts a modular design composed of the combing needle blocks 212, so that each combing needle block 212 can move independently, reducing the influence of the overall weight of the combing needle base 211 on the movement of the combing needle block 212. When the combing needle 213 on a certain combing needle block 212 touches the debris in the limiting cluster, only the combing needle block 212 can be swung in the installation groove 11, which further improves the buffering capacity of the combing needle unit 21 and further protects the combing needle 213 with a relatively fragile structure.

[0035] Furthermore, a fixed shaft 214 is provided in the middle of several of the combing needle blocks 212, and the fixed shaft 214 is arranged parallel to the axial direction of the cylinder roller 1. The combing needle blocks 212 are rotatably connected to the fixed shaft 214, and the fixed shaft 214 can fix and connect several fixed blocks in series. When the combing needle base 211 needs to be replaced, the entire combing needle base 211 can be taken out from the mounting groove 11 through the fixed shaft 214, which facilitates the replacement of the combing needle base 211, so that the cylinder can meet the working requirements of the combing work, and the cotton drop rate of the combing machine can be maintained at about 15%.

[0036] For further information, see Figure 1 and Figure 3 The two ends of the cylinder roller 1 are movably connected with a closed cover plate 12, and the closed cover plate 12 is provided with a fixing hole 13 at a relative position of the fixed shaft 214. The fixing hole 13 can accommodate the two ends of the fixed shaft 214 to be inserted and fixed, thereby fixing the two ends of the fixed shaft 214 and sealing the two ends of all the mounting grooves 11.

[0037] Furthermore, a movably connected sealing plate is provided at the opening on the outward side of the mounting groove 11, and the combing needle 213 can extend through the sealing plate. The length of the sealing plate is greater than the length of the mounting groove 11, and its two ends can extend from the two ends of the mounting groove 11. The closing cover plate 12 is provided with a plurality of sealing grooves (14) on the side facing the cylinder roller 1. The shape of the sealing groove (14) matches the cross-sectional shape of the sealing plate, and the two ends of the sealing plate can be inserted into the sealing groove 14 for fixation. The setting of the sealing plate can seal the mounting groove 11 to prevent the combed fibers or debris from entering the mounting groove 11 during the combing process, thereby affecting the swing of the combing needle block 212 in the mounting groove 11.

[0038] See also Figure 2The transverse cross-section of the combing needle block 212 is also fan-shaped, and the central angle of the transverse cross-section of the combing needle block 212 is 10-20 degrees smaller than the central angle of the transverse cross-section of the mounting groove 11, thereby ensuring that there is sufficient space between the combing needle block 212 and the side wall of the mounting groove 11 to allow the combing needle block 212 to perform buffering swing in the mounting groove 11, ensuring soft contact between the combing needles 213 and debris in the fiber bundle.

[0039] For further information, see Figure 4 The elastic reset member is a spring sheet 215 fixed to the side of the combing needle block 212 facing the side wall of the installation groove 11. The shape of the spring sheet 215 includes an arc. When the combing needles 213 on the combing needle block 212 touch the debris in the fiber bundle, under the action of the resistance of the debris, the combing needle block 212 will swing in the installation groove 11 in the opposite direction of the rotation of the cylinder roller 1, so that a soft contact is formed between the combing needles 213 and the debris, thereby avoiding deformation or wear and tear of the combing needles 213. In this process, the corresponding spring sheet 215 will also be compressed and deformed, generating a reaction force in the opposite direction of the swinging direction of the combing needle block 212, thereby pushing the combing needle block 212 to return to its original default position in the installation groove 11.

[0040] Preferably, raised positioning buttons 222 are provided at both ends of the balancing bar 221 , and the shape of the positioning buttons 222 matches the shape of the fixing hole 13 , so that the closing cover 12 can also fix the balancing bar 221 installed in the installation groove 11 .

[0041] As a preference, see Figure 1 The sealing plate installed at the opening of the mounting groove 11 where the combing base is installed is a first sealing plate 23. The first sealing plate 23 is provided with a combing needle hole 25 at a position relative to the combing needle 213. The combing needle hole 25 is in the shape of a long strip and can accommodate the combing needle 213 to move therein. The sealing plate installed at the opening of the mounting groove 11 where the balancing bar 221 is installed is a second sealing plate 24. The second sealing plate 24 can seal the mounting groove 11 where the balancing bar 221 is located to prevent the combed fibers or debris from entering.
