Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a cotton carding machine. Background Art

[0002] The carding machine is a professional processing equipment for the spinning and carding process. Its working principle is to open, comb and remove impurities from the cotton (fiber) rolls sent from the previous process or the cotton (chemical fiber) layer supplied by the cotton box, so that all the curly block-shaped cotton bundles (or cotton blocks) become basically straight single fibers. In this process, impurities, short fibers and cotton knots in the cotton layer are removed, and then the stripping rollers and the upper and lower crushing rollers 3 transfer and aggregate the carded cotton web into strips. According to the requirements of the type and quality of the spinning, the output of a single domestic carding machine now ranges from 40kg / h to 120kg / h.

[0003] Crushing roller and scraper plate are important working parts inside the carding machine. Crushing roller is a pair of smooth rollers with the same diameter and set up and down at a certain angle. Spiral grooves are opened on the smooth rollers according to certain size requirements. According to the installation position, the crushing roller set at the bottom is called the lower crushing roller 3, and the crushing roller set at the top is called the upper crushing roller 2. In the carding process, the process distance refers to the distance between the outer surfaces of different parts in the equipment, such as Figure 1 The gap between the middle and lower crushing roller 3 and the upper crushing roller 2 is called the process gauge of the crushing roller. This process gauge can be adjusted within a certain range according to the type and output of the spinning. The scraper plate is used in conjunction with the crushing roller. Depending on the installation position, the upper scraper plate 1 is called the upper scraper plate 1, and the lower scraper plate 4 is called the lower scraper plate 4.

[0004] In the prior art, the lower scraper plate 4 and the lower crushing roller 3 are tightly fitted together under a certain preload, and the upper scraper plate 1 and the upper crushing roller 2 are tightly fitted together under a certain preload. There is a certain gap between the lower crushing roller 3 and the upper crushing roller 2 (the gap is professionally called the process gauge, and the process gauge value is usually 0.175-0.25 mm). When the carding machine is working, the lower crushing roller 3 and the upper crushing roller 2 rotate synchronously and at high speed in opposite directions to transfer the cotton web from the stripping roller. During the cotton web output process, due to the interaction between the lower crushing roller 3, the upper crushing roller 2 and the cotton web in stripping, squeezing, and transfer output, the roller surfaces of the lower crushing roller 3 and the upper crushing roller 2 are often covered with some cotton webs, short fibers, dust, impurities, etc. that have not been transferred away. These substances need to be removed by the action of the lower scraper plate 4 and the upper scraper plate 1. When there are a lot of sticky coatings on the surfaces of the lower crushing roller 3 and the upper crushing roller 2, flowers will accumulate between the scraper plate and the crushing rollers.

[0005] The lint accumulation between the lower scraper plate 4 and the lower crushing roller 3 of the carding machine is related to factors such as the output of the carding machine and the varieties spun (e.g., the sugar content of cotton fibers, the fiber characteristics of chemical fibers). The triangular area 5 between the lower crushing roller 3 and the lower scraper plate 4 is prone to accumulate short fibers, dust, etc. When the carding machine is working, lint and dust often accumulate in the triangular area 5 between the lower crushing roller 3 and the lower scraper plate 4. During the high-speed rotation of the lower crushing roller 3, some of this accumulated lint and dust will re-enter the cotton web, resulting in an increase in the number of yarn defects in the corresponding yarn and affecting the yarn quality.

[0006] To ensure the cleaning power of the lower scraper plate 4, the lower scraper plate 4 and the lower crushing roller 3 are closely attached under a certain pre-tightening force, and the adhering substances on the surface of the lower crushing roller 3 are removed through the scraping action of the lower scraper plate 4. When the carding machine is working, the lower scraper plate 4 and the lower crushing roller 3 rub violently for a long time, frequently causing severe wear of the lower scraper plate 4 and shortening the service life of the scraper plate; due to the long-term friction, the pre-tightening force of the lower scraper plate 4 attached to the lower crushing roller 3 will become loose, so the maintenance worker needs to regularly check and adjust the gap and pre-tightening force between the lower scraper plate 4 and the lower crushing roller 3.

[0007] When the carding machine is working, due to the close contact and violent friction between the lower scraper plate 4 and the lower crushing roller 3, the temperature of the lower crushing roller 3 rises relatively high. The relatively high temperature will cause a certain amount of deformation of the crushing roller, thereby affecting the stability of the process gauge between the upper and lower crushing rollers 3 and the transfer of the cotton web. The unsmooth transfer of the cotton web causes stop due to breakage, affecting the normal operation of the carding machine.

[0008] In summary, how to effectively solve the problem that the triangular area formed by the lower scraper plate, the lower base and the lower crushing roller is prone to lint and dust accumulation is an urgent problem that needs to be solved by those skilled in the art at present. Utility Model Content

[0009] The purpose of the present utility model is to provide a carding machine, which effectively solves the problem that the triangular area formed by the lower scraper plate, the lower base and the lower crushing roller is prone to lint and dust accumulation.

[0010] To solve the above technical problems, the present utility model provides the following technical solutions:

[0011] A carding machine includes a lower crushing roller and an upper crushing roller installed on a frame, a lower scraper plate and an upper scraper plate respectively arranged outside the lower crushing roller and the upper crushing roller through a lower base and an upper base. The lower scraper plate and the lower base are both arranged directly below the lower crushing roller. The length direction of the lower scraper plate is the same as the length direction of the lower crushing roller. The lower scraper plate is along the vertical direction, the lower scraper plate is non-contact with the lower crushing roller, and there is a set process gauge between the upper surface of the lower scraper plate and the surface of the lower crushing roller.

[0012] Preferably, the extension line of the lower scraper plate passes through the center of the lower crushing roller.

[0013] Preferably, the lower base is detachably connected to the lower scraper plate, and the length of the lower scraper plate connected to the lower base is adjustable.

[0014] Preferably, vertical long slots are provided on the mating surface of the lower base, round holes are provided on the lower scraper plate, and the lower base and the lower scraper plate are connected by bolts, and the bolts can move along the vertical long slots.

[0015] Preferably, the mating surface of the lower base is in the vertical direction, the lower scraper plate is in contact with the mating surface of the lower base, and the height of the lower scraper plate in contact with the mating surface is one-third to one-half of the total height of the lower scraper plate.

[0016] Preferably, the lower base and the lower scraper plate are provided with matching concave and convex vertical ribs on the mating surface.

[0017] Preferably, a bracket is provided at the lower end of the mating surface of the lower base, a convex rib along the length direction of the lower scraper plate is connected to the bracket, a groove matching the convex rib is provided on the lower surface of the lower scraper plate, the groove is stuck on the convex rib, and the lower scraper plate is attached to the mating surface, and the convex rib is connected to the bracket for lifting and lowering.

[0018] Preferably, the lowest surface of the lower crushing roller is parallel to the highest surface of the lower scraper plate, and a translation adjustment device for controlling the parallel lifting and lowering of the convex rib is further included.

[0019] Preferably, the translation adjustment device includes:

[0020] A first distance sensor for detecting the distance between the first end of the convex rib and the lowest surface of the first end of the lower crushing roller;

[0021] A second distance sensor for detecting the distance between the second end of the convex rib and the lowest surface of the second end of the lower crushing roller;

[0022] A translation adjustment mechanism connected to both the first distance sensor and the second distance sensor for controlling the distance detected by the first distance sensor to be equal to the distance detected by the second distance sensor.

[0023] Preferably, the lower base is rotationally connected to the frame, the rotation axis of the lower base is parallel to the rotation axis of the lower crushing roller, and the carding machine further includes an angle adjustment device for controlling the mating surface of the lower base to be in the vertical direction during operation.

[0024] The cotton carding machine provided by the utility model has a certain process spacing between the lower crushing roller and the upper crushing roller. When the cotton carding machine is working, the lower crushing roller and the upper crushing roller rotate synchronously and at high speed in opposite directions to transfer and output the cotton web from the cotton stripping roller. The lower scraper plate and the upper scraper plate are respectively arranged on the outer sides of the lower crushing roller and the upper crushing roller through the lower base and the upper base. These materials need to be removed by the action of the lower scraper plate and the upper scraper plate to avoid the accumulation of flowers between the scraper plate and the crushing roller when there are many sticky coatings on the surfaces of the lower crushing roller and the upper crushing roller.

[0025] The lower scraper plate is installed on the lower base. The length direction of the lower scraper plate is the same as that of the lower crushing roller. The two ends of the lower base are fixed to the left and right cotton stripping roller wall panels through a rotating shaft. The lower scraper plate and the lower base are arranged together under the lower crushing roller. The lower scraper plate is non-contacting with the lower crushing roller. There is a set process spacing between the upper surface of the lower scraper plate and the surface of the lower crushing roller. The height of the lower scraper plate can be adjusted upward or downward within a certain range. There is basically no narrow "triangle area" in the area formed by the lower scraper plate, the lower base and the lower crushing roller in the vertical direction. The release of space allows the airflow driven by the high-speed rotation of the lower crushing roller to be fully released, and no turbulence will be generated in the area, and no flower or dust will be accumulated during the production process.

[0026] The cotton combing machine provided by the utility model has the positions of the lower crushing roller, the upper crushing roller and other related parts remaining unchanged, the relative working positions of the lower scraper plate, the lower base and the lower crushing roller are optimized, and the lower scraper plate and the lower crushing roller are changed to a non-contact structure. By optimizing the structure, the space formed by the lower scraper plate, the lower base and the lower crushing roller is released. When the cotton combing machine is working, the airflow driven by the high-speed rotation of the lower crushing roller can be completely released, and no turbulence will be generated in the regional position. Since there is a process spacing between the lower scraper plate and the lower crushing roller, and the lower scraper plate is placed vertically, the lower scraper plate can effectively isolate the airflow problem caused by the high-speed rotation of the lower crushing roller, and also clean the surface of the lower crushing roller. A small amount of cotton nets, short fibers, dust, impurities and other materials cleaned by the lower scraper plate fall to the bottom plate of the cotton combing machine under the action of gravity. A certain process distance is maintained between the lower scraper plate and the lower crushing roller. The lower crushing roller rotates without contacting the lower scraper plate, so the damage rate of the lower scraper plate is reduced, and the service life of the lower scraper plate is increased; there is no need to adjust or check the preload force, which reduces the labor intensity of workers; the lower crushing roller does not have temperature rise due to friction, which reduces the temperature rise of the lower crushing roller.

[0032] The core of the present invention is to provide a carding machine, which effectively solves the problem that the triangular area formed by the lower scraper plate, the lower base and the lower crushing roller is prone to lint accumulation and dust accumulation.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] Please refer to Figure 2 , Figure 2 It is a schematic diagram of the structure of the carding machine provided by a specific embodiment of the present invention.

[0035] In a specific implementation mode, the carding machine provided by the present invention includes a lower crushing roller 3 and an upper crushing roller 2 installed on a frame, a lower scraper plate 4 and an upper scraper plate 1 respectively arranged outside the lower crushing roller 3 and the upper crushing roller 2 through a lower base 6 and an upper base. The lower scraper plate 4 and the lower base 6 are both arranged directly below the lower crushing roller 3. The length direction of the lower scraper plate 4 is the same as the length direction of the lower crushing roller 3. The lower scraper plate 4 is along the vertical direction. The lower scraper plate 4 is non-contact with the lower crushing roller 3. There is a set process gap between the upper surface of the lower scraper plate 4 and the surface of the lower crushing roller 3.

[0036] In the above structure, the carding machine includes a lower crushing roller 3, an upper crushing roller 2, a lower base 6, an upper base, a lower scraper plate 4, and an upper scraper plate 1. There is a certain process gap between the lower crushing roller 3 and the upper crushing roller 2, and generally, the value of this process gap is 0.175 - 0.25 mm. When the carding machine is working, the lower crushing roller 3 and the upper crushing roller 2 rotate synchronously and at high speed towards each other to transfer and output the cotton web from the doffer roller. Rotating towards each other means that two objects move towards each other's directions respectively, and their rotation directions are opposite. During the output process of the cotton web, due to the interactions such as stripping, squeezing, and transfer output between the lower crushing roller 3, the upper crushing roller 2, and the cotton web, some substances such as untransferred cotton web, short fibers, dust, and impurities often adhere to the roller surfaces of the lower crushing roller 3 and the upper crushing roller 2. The lower scraper plate 4 and the upper scraper plate 1 are respectively arranged outside the lower crushing roller 3 and the upper crushing roller 2 through the lower base 6 and the upper base, and these substances need to be removed under the action of the lower scraper plate 4 and the upper scraper plate 1 to avoid the accumulation of lint between the scraper plate and the crushing roller when there is a lot of adhesion on the roller surfaces of the lower crushing roller 3 and the upper crushing roller 2. Among them, since the upper crushing roller 2 is in contact with the doffer roller, during operation, the airflow will be transferred away by the doffer roller. Therefore, the upper scraper plate 1 and the upper crushing roller 2 can be closely attached together under the action of a certain pre-tightening force. Although there is a triangular area between the upper scraper plate 1 and the upper crushing roller 2, no lint accumulation occurs.

[0037] The lower scraper plate 4 is installed on the lower base 6. The length direction of the lower scraper plate 4 is the same as the length direction of the lower crushing roller 3. Both ends of the lower base 6 are fixed on the left and right doffer roller wallboards through rotating shafts. The lower scraper plate 4 and the lower base 6 are arranged together below the lower crushing roller 3. The lower scraper plate 4 is non-contact with the lower crushing roller 3. There is a set process gap between the upper surface of the lower scraper plate 4 and the surface of the lower crushing roller 3. The height position of the lower scraper plate 4 can be adjusted upward or downward within a certain range. During normal production, the minimum process gap between the upper surface of the lower scraper plate 4 and the surface of the lower crushing roller 3 can be 0.1 - 0.125 mm, which can not only clean the lower crushing roller 3 thoroughly but also avoid lint accumulation.

[0038] The lower scraper plate 4 is along the vertical direction. The area 7 formed among the lower base 6 and the lower crushing roller 3 basically has no narrow "triangular area". The release of the space enables the airflow driven by the high-speed rotation of the lower crushing roller 3 to be completely released, and no turbulent flow will be generated at the position of the area 7, and no lint or dust accumulation will occur during the production process.

[0039] In the carding machine provided by the present utility model, the positions of relevant components such as the lower crushing roller 3 and the upper crushing roller 2 remain unchanged, and the relative working positions of the lower scraper plate 4 and the lower base 6 with respect to the lower crushing roller 3 are optimized, and the lower scraper plate 4 and the lower crushing roller 3 are changed to a non-contact structure. By optimizing the structure, the space of the area 7 formed among the lower scraper plate 4, the lower base 6, and the lower crushing roller 3 is released. Compared with the original technology Figure 1In the triangular area 5, the present utility model Figure 2 When the carding machine is working in area 7, the airflow driven by the high-speed rotation of the lower crushing roller 3 can be completely released, and no turbulence will be generated at the position of area 7. Since there is a process gap between the lower scraper plate 4 and the lower crushing roller 3, and at the same time the lower scraper plate 4 is vertically placed, the lower scraper plate 4 not only effectively isolates the airflow problem brought by the high-speed rotation of the lower crushing roller 3, but also cleans the surface of the lower crushing roller 3. A little cotton web, short fibers, dust, impurities and other substances cleaned by the lower scraper plate 4 fall onto the bottom plate of the carding machine under the action of gravity. A certain process gap is maintained between the lower scraper plate 4 and the lower crushing roller 3, and the lower crushing roller 3 does not contact the lower scraper plate 4 during rotation, so the damage rate of the lower scraper plate 4 is reduced, and the service life of the lower scraper plate 4 is increased; there is no need to adjust and check the pre-tightening force, which reduces the labor intensity of workers; the lower crushing roller 3 does not have temperature rise due to friction, and the temperature rise of the lower crushing roller 3 is reduced.

[0040] Based on the above various specific embodiments, the extension line of the lower scraper plate 4 passes through the center of the circle of the lower crushing roller 3. In other words, the lower scraper plate 4 is located directly below the vertical diameter of the lower crushing roller 3, that is, directly below the lowest point of the lower crushing roller 3. At this time, when the process gap between the lower scraper plate 4 and the lower crushing roller 3 is the same, the length of the lower scraper plate 4 is the smallest, and this position is the position where the lower scraper plate 4 is closest to the lower crushing roller 3. Even if the lower scraper plate 4 rotates by an angle relative to the vertical plane, the lower scraper plate 4 will not contact any surface of the lower crushing roller 3, avoiding mutual interference between the lower scraper plate 4 and the lower crushing roller 3.

[0041] Based on the above various specific embodiments, the lower base 6 is detachably connected to the lower scraper plate 4, and the length of the lower scraper plate 4 connected to the lower base 6 is adjustable.

[0042] In one embodiment, the lower scraper plate 4 is made of wear-resistant material, such as a plastic plate or a rubber plate. When the lower scraper plate 4 is severely worn or deformed, the lower scraper plate 4 can be detached from the lower base 6 for replacement. The process gap between the upper surface of the lower scraper plate 4 and the surface of the lower crushing roller 3 can be adjusted by the length of the lower scraper plate 4 connected to the lower base 6. The process gap is stepless adjustment, with high adjustment accuracy and convenient adjustment.

[0043] Based on the above various specific embodiments, vertical long holes are provided on the mating surface of the lower base 6, round holes are provided on the lower scraper plate 4, and the lower base 6 and the lower scraper plate 4 are connected by bolts, and the bolts can move along the vertical long holes. The height position of the lower scraper plate 4 connected to the lower base 6 is adjusted by the position of the bolts in the vertical long holes. The structure is simple, which is convenient for the connection and adjustment of the lower base 6 and the lower scraper plate 4.

[0044] Based on the above specific embodiments, the mating surface of the lower base 6 is in the vertical direction, the lower scraper plate 4 contacts the mating surface of the lower base 6, and the height at which the lower scraper plate 4 contacts the mating surface is one-third to one-half of the total height of the lower scraper plate 4.

[0045] In a specific embodiment, the lower scraper plate 4 is always in contact with the vertical mating surface of the lower base 6, that is, the supporting surface of the lower scraper plate 4 is in the vertical direction. The lower scraper plate 4 fitting the mating surface of the lower base 6 can also ensure that the lower scraper plate 4 is in the vertical direction, reducing the difficulty of adjusting the position and angle of the lower scraper plate 4.

[0046] The contact height between the lower scraper plate 4 and the mating surface is more than one-third of the height of the lower scraper plate 4. The supporting area of the mating surface for the lower scraper plate 4 is relatively large, reducing the shaking of the lower scraper plate 4 and improving the stability of the lower scraper plate 4. Optionally, the mating surface starts from the lower end of the lower scraper plate 4 to support the root of the lower scraper plate 4, strengthening the foundation stability of the lower scraper plate 4. And the contact height between the lower scraper plate 4 and the mating surface is less than one-half of the height of the lower scraper plate 4. The mating surface does not support the upper part of the lower scraper plate 4, having no influence on the adjustment of the upper part of the lower scraper plate 4 and the scraping of debris on the lower crushing roller 3.

[0047] Based on the above specific embodiments, the lower base 6 and the lower scraper plate 4 are provided with matching concave and convex vertical ribs on the mating surface.

[0048] In a specific embodiment, the mating surface of the lower base 6 is provided with concave vertical ribs, and the lower scraper plate 4 is provided with convex vertical ribs on the mating surface. The concave vertical ribs and the convex vertical ribs cooperate with each other. During the height adjustment process of the lower scraper plate 4, the concave vertical ribs and the convex vertical ribs have a vertical guiding effect on the lower scraper plate 4, preventing the left and right displacement of the lower base 6 and the lower scraper plate 4, eliminating the horizontal position adjustment process; and during the height adjustment, the mating surface of the lower base 6 always supports the lower scraper plate 4, without affecting the perpendicularity of the lower scraper plate 4 and without increasing the perpendicularity adjustment process.

[0049] Based on the above specific embodiments, a bracket is provided at the lower end of the mating surface of the lower base 6, and the lower scraper plate 4 abuts against the bracket. The bottom of the lower scraper plate 4 is supported by the bracket, preventing the lower scraper plate 4 from falling or slipping downward and maintaining the stability of the lower scraper plate 4.

[0050] Based on the above specific embodiments, a convex rib along the length direction of the lower scraper plate 4 is connected to the bracket, and a groove matching the convex rib is provided on the lower surface of the lower scraper plate 4. The groove is stuck on the convex rib, and the lower scraper plate 4 fits on the mating surface. The groove and the convex rib of the lower scraper plate 4 are clamped, ensuring that the bottom of the lower scraper plate 4 does not slip and the lower scraper plate 4 stably fits on the mating surface.

[0051] The convex rib is vertically and adjustably connected to the support, and the height of the convex rib can be adjusted to adapt to the height of the lower scraper plate 4, ensuring that the convex rib can always support the lower scraper plate 4.

[0052] On the basis of the above specific embodiments, the lowest surface of the lower crushing roller 3 is parallel to the highest surface of the lower scraper plate 4, and a translational adjustment device for controlling the parallel lifting of the convex rib is further included.

[0053] In practical applications, the convex rib moves translationally in the vertical direction, that is, the lifting heights of the left and right ends are equal, keeping the lowest surface of the lower crushing roller 3 parallel to the highest surface of the lower scraper plate 4. In the axial direction, the process gap between the lower crushing roller 3 and the lower scraper plate 4 is equal, preventing the lower scraper plate 4 from colliding with the lower crushing roller 3 or the lower scraper plate 4 being unable to scrape off the debris on the lower crushing roller 3 due to unequal distances between the lower scraper plate 4 and the lower crushing roller 3.

[0054] On the basis of the above specific embodiments, the translational adjustment device includes:

[0055] A first distance sensor for detecting the distance between the first end of the convex rib and the lowest surface of the first end of the lower crushing roller 3;

[0056] A second distance sensor for detecting the distance between the second end of the convex rib and the lowest surface of the second end of the lower crushing roller 3;

[0057] A translational adjustment mechanism connected to both the first distance sensor and the second distance sensor for controlling the distance detected by the first distance sensor to be equal to the distance detected by the second distance sensor.

[0058] In practical applications, the translational adjustment device may include a first distance sensor, a second distance sensor, and a translational adjustment mechanism. The first distance sensor is installed at the first end of the convex rib for detecting the distance between the first end of the convex rib and the lowest surface of the first end of the lower crushing roller 3. The second distance sensor is installed at the second end of the convex rib for detecting the distance between the second end of the convex rib and the lowest surface of the second end of the lower crushing roller 3. The first distance sensor and the second distance sensor send the detected distance information to the translational adjustment mechanism, and the translational adjustment mechanism compares the distance detected by the first distance sensor with the distance detected by the second distance sensor. When the distance detected by the first distance sensor is not equal to the distance detected by the second distance sensor, the distance detected by the first distance sensor is adjusted to be equal to the distance detected by the second distance sensor.

[0059] Specifically, when the distances detected by the first distance sensor and the second distance sensor are both within the set process gap range, keep the distance at one end unchanged and adjust the distance at the other end to make it equal to the distance at the end with the unchanged distance; when one of the distances detected by the first distance sensor and the second distance sensor is within the set process gap range and the other is not, adjust the end that is not within the set process gap range to make its distance equal to the end that is within the set process gap range; when the distances detected by the first distance sensor and the second distance sensor are both not within the set process gap range, first adjust one end to within the set process gap range, and then adjust the other end to be equal to the distance of the first end. Ensure that the distances between both ends of the lower scraper plate 4 and the lower crushing roller 3 are equal, avoiding the situation where one end is high and the other is low, causing the lower scraper plate 4 at the end with a small distance to collide with the lower crushing roller 3, and the lower scraper plate 4 at the end with a large distance cannot scrape off the debris on the lower crushing roller 3.

[0060] Based on each of the above specific embodiments, the lower base 6 is rotatably connected to the frame, the rotation axis of the lower base 6 is parallel to the rotation axis of the lower crushing roller 3, and the carding machine further includes an angle adjustment device for controlling the angle of the mating surface of the lower base 6 in the vertical direction during operation.

[0061] In practical applications, before work, the angle adjustment device rotates the lower base 6 outwards, the mating surface of the lower base 6 forms an obtuse angle with the horizontal plane, and the distance from the lower base 6 to the lower crushing roller 3 increases, facilitating the installation of the lower scraper plate 4. During the working state, the angle adjustment device adjusts the mating surface of the lower base 6 to be in the vertical direction, releasing the space of the area 7 formed among the lower scraper plate 4, the lower scraper plate 4 seat, and the lower crushing roller 3. No turbulence will occur in the area 7, effectively solving the problems of lint and dust accumulation between the lower scraper plate 4 and the lower crushing roller 3.

[0062] In a preferred embodiment, it further includes a distance adjustment device for controlling the process gap between the lowest point of the lower crushing roller 3 and the highest point of the lower scraper plate 4.

[0063] In a preferred embodiment, it further includes a position adjustment device for controlling the parallelism between the lowest surface of the lower crushing roller 3 and the highest surface of the lower scraper plate 4.

[0064] By adjusting the position of the lower scraper plate 4 and the process gap between the lowest point of the lower crushing roller 3 and the highest point of the lower scraper plate 4 through the distance adjustment device and the position adjustment device, the process gap between the lowest point of the lower crushing roller 3 and the highest point of the lower scraper plate 4 is more accurate, improving the quality of the yarn.

[0065] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts between the various embodiments, reference can be made to each other.

[0066] The above has introduced the carding machine provided by the present utility model in detail.
