[0002] The spinning process mainly spins the semi-finished roving obtained in the roving process into spun yarn with yarn count that meets the requirements. As an important process in the textile process, the quality of spun yarn directly affects the performance of yarn and fabric. The spun yarn roller in the spun yarn equipment has an important influence on the quality of spun yarn. Figure 1 The existing spinning roller 100 generally includes a roller shaft 101, and roller skins 102 are wrapped at both ends of the roller shaft 101, wherein the roller skins 102 and the roller shaft 101 can rotate relative to each other. During the drafting process of the yarn, impurities and short fibers in the sliver are also easily attached to the surface of the roller skin, and when accumulated to a certain extent, it is easy to affect the quality of the spinning. Therefore, the spinning roller needs to be cleaned in time to ensure the yarn quality and the normal operation of the spinning equipment.

[0003] At present, the spun yarn rollers of most textile factories are basically cleaned manually after being removed, but manual cleaning is time-consuming and laborious, and it is also easy to be incompletely cleaned. Moreover, the cleaning devices of the spun yarn rollers are mostly to support the spun yarn rollers through flat belts for transmission, and the spun yarn rollers are cleaned by brushing tools during the cleaning process, but there is friction between the spun yarn rollers and the flat belts, which makes the spun yarn rollers difficult to rotate and incompletely cleaned. In view of this problem, it is necessary to propose an automatic cleaning device for spun yarn rollers to improve the cleaning degree and efficiency, reduce labor costs and ensure the quality of spun yarn.

[0004] Therefore, the prior art still needs to be improved and developed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model provides an automatic cleaning device for a spun yarn roller. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] Reference Figure 2-Figure 3, the arrow direction in the figure indicates the forward direction of the roving roller 100, the utility model provides an automatic cleaning device for roving rollers, comprising a rolling feed channel 1 and a conveyor belt 2, the conveyor belt 2 is provided with a plurality of grippers 21 matched with the roller shaft 101 in the middle of the roving roller 100, the bottom surface at the end of the rolling feed channel 1 is provided with an avoidance groove 11 for the grippers 21 to pass through and grab the roving roller 100, the grippers 21 on the starting section of the conveyor belt 2 are in the avoidance groove 11 and matched with the roving roller 100 at the end of the rolling feed channel 1, and a brush 3 acting on the roving roller 100 is provided above the conveyor belt 2. Among them, the rolling feed channel 1, the conveyor belt 2 and the brush 3 can be installed on a frame (not shown in the figure).

[0027] The working principle of the automatic cleaning device of the roving roller 100 is as follows: the roving roller 100 is fed through a rolling feed channel 1; an avoidance groove 11 is provided on the bottom surface at the end of the rolling feed channel 1 for a gripper 21 to pass through and grab the roving roller 100; a gripper 21 is provided on the conveyor belt 2 to cooperate with a roller shaft 101 in the middle of the roving roller 100; the gripper 21 at the starting section grabs the roller shaft 101 in the middle of the roving roller 100 when passing through the avoidance groove 11; the roving roller 100 on the conveyor belt 2 can be cleaned by the brush 3 arranged above the conveyor belt 2 during the cleaning process.

[0028] The automatic cleaning device for the spun yarn roller 100 provided by the utility model can grab the roller shaft 101 in the middle of the spun yarn roller 100 by the gripper 21 when passing through the avoidance groove 11, so that the roller skin 102 of the spun yarn roller 100 can be kept suspended during the cleaning process, and can be easily affected by the brush 3 to rotate during cleaning, thereby improving the cleaning degree of the spun yarn roller 100. The device can automatically clean the spun yarn roller 100, which can save manpower and greatly improve the cleaning efficiency.

[0029] In a specific embodiment of the utility model, the gripper 21 is fixed on the conveyor belt 2 through the lifting arm 22, and the gripper 21 is a "C"-shaped gripper. The gripper 21 can be set as a mechanical hand with a sensor, which performs a gripping action when passing through the avoidance groove 11 and automatically releases when running to the discharge position of the conveyor belt 2, but such a mechanical gripper also needs to be provided with another power source at the gripper 21, and the design is complicated. The utility model sets the gripper 21 in a "C" shape, so that the "C" gripper on the starting section can hook the roller shaft 101 of the spun yarn roller 100 at the end of the rolling feed channel 1 when passing through the avoidance groove 11. At the same time, this shape can also ensure that the spun yarn roller 100 is in the gripper 21 for cleaning during horizontal operation. When the "C" gripper is turned downward with the conveyor belt 2, the spun yarn roller 100 can also be separated from the gripper 21 from the "C"-shaped opening. The automatic gripping and releasing of the spun yarn roller 100 can be achieved through simple shape matching, which is efficient and durable. Among them, the gripper 21 can be fixed on the conveyor belt 2 at equal intervals, and can be fixed on the conveyor belt 2 specifically by a lifting arm 22. The lifting arm 22 can be a cylindrical metal rod, and the gripper 21 is connected and fixed on the conveyor belt 2. During the cleaning process, the roller shaft 101 of the roving roller 100 may also rotate. The gripper 21 is fixed by the lifting arm 22 to reduce the direct impact of the cleaning process on the conveyor belt 2, thereby ensuring that the cleaning process runs for a long time.

[0030] In a specific embodiment of the present invention, the opening angle of the "C" type gripper is 90°-120°, and the opening direction is at an angle of 30°-60° with the traveling direction of the "C" type gripper. The opening of the "C" type gripper faces the traveling direction of the spun yarn roller 100. By controlling the opening direction and angle of the "C" type gripper, it is ensured that the spun yarn roller 100 can be grasped, and the spun yarn roller 100 will not be separated from the "C" type gripper during the cleaning process, and the spun yarn roller 100 can also be separated from it when the conveyor belt 2 is turned downward.

[0031] In a specific embodiment of the utility model, cleaning baffles 23 may also be provided on both sides of the conveyor belt 2. The cleaning baffles 23 may be installed on the frame to further ensure that the cleaned spun yarn roller 100 on the conveyor belt 2 does not separate from the gripper 21.

[0032] In a specific embodiment of the present invention, the rolling feed channel 1 can be in the shape of a slide so that the roving roller 100 can roll and feed. The rolling speed of the roving roller 100 can be controlled by adjusting the inclination angle of the rolling feed channel 1 to facilitate coordination with the cleaning speed.

[0033] In a specific embodiment of the utility model, a blocking portion 12 is provided at the end of the rolling feed channel 1 to limit the free rolling of the roving roller 100. The width of the blocking portion 12 is the same as the width of the roller skin 102 of the roving roller 100. The height of the blocking portion 12 is not greater than the diameter of the roller skin 102 and not less than the radius of the roller skin 102. The blocking portion 12 is parallel to the roving roller 100, specifically parallel to the roving roller 100 rolling down in the rolling feed channel 1, perpendicular to the advancing direction of the roving roller 100, and arranged horizontally. The feeding speed of the roving roller 100 can be coordinated with the running speed of the conveyor belt 2, so that the roving roller 100 passing through the rolling feed channel 1 just falls on the gripper 21 at the starting section of the conveyor belt 2, but due to the inertia of rolling, it is easy to affect the conveyor belt 2, and the shape of the gripper 21 is also easy to deform over a long period of time. The utility model sets a blocking portion 12 to limit the free rolling of the roving roller 100, and the roving roller 100 is grabbed by the gripper 21 in the rolling feed channel 1 in a stationary state, which is more efficient and easy to adjust the speed coordination. Moreover, through the shape setting of the utility model, the roving roller 100 after stopping can be perpendicular to the forward direction of the roving roller 100 and maintain a horizontal horizontal setting, which is easier to be grabbed by the running gripper 21. Since the starting section of the conveyor belt 2 passes through the avoidance groove 11 of the rolling feed channel 1, and the blocking portion 12 is set at the end of the rolling feed channel 1, by controlling the height of the blocking portion 12, it can be ensured that the roving roller 100 will not roll out of the rolling feed channel 1 while not interfering with the conveyor belt 2.

[0034] In a specific embodiment of the utility model, baffles 13 are provided on both sides of the rolling feed channel 1, and the bottom plate of the rolling feed channel 1 has the same width as the spun yarn roller 100, and the baffles 13 can be installed on the frame. By providing the baffles 13 and the bottom plate with the same width as the spun yarn roller 100, after the spun yarn roller 100 is stopped by the blocking part 12, it can ensure that the spun yarn rollers 100 that have rolled down one after another can also be arranged in order, which is conducive to the gripper 21 to grab.

[0035] In a specific embodiment of the utility model, a cleaning nozzle 31 is arranged above the conveyor belt 2 to shoot at the spun yarn roller 100. According to the forward direction of the spun yarn roller 100, the cleaning nozzle 31 is arranged before the brush 3. The cleaning nozzle 31 can be installed on the frame or on the cleaning baffle 23. The cleaning agent and water are sprayed out by the cleaning nozzle 31 to wet the roller skin 102 surface of the spun yarn roller 100, and then the roller skin 102 surface is brushed and cleaned by the brush 3. Among them, the number of brushes 3 can be set to multiple, and the number of cleaning nozzles 31 can also be set according to actual conditions. Specifically, only one cleaning nozzle 31 can be set before the first brush 3, or a cleaning nozzle 31 can be set before each brush 3.

[0036] In a specific embodiment of the utility model, according to the advancing direction of the spun yarn roller 100, a rinsing device 32 is provided above the conveyor belt 2 to spray toward the spun yarn roller 100. The rinsing device 32 is provided after the brush 3 provided last. The rinsing device 32 can be installed on the frame or on the cleaning baffle 23. After cleaning by the cleaning nozzle 31 and the brush 3, the cleaning agent that may remain on the spun yarn roller 100 is cleaned by spraying water through the rinsing device 32 to avoid corrosion of the spun yarn roller 100 by the residual cleaning agent.

[0037] In a specific embodiment of the present invention, the brush 3 is a round brush. The round brush can be installed on the frame or on the cleaning baffle 23. The cleaning method of the round brush is simple and easy to set or adjust. The round brush can be set in parallel with the spun yarn roller 100, and the spun yarn roller 100 can be brushed by simply rotating it.

[0038] In some specific embodiments, before the spun yarn roller 100 is affected by the round brush during the cleaning stage, the roller skin 102 of the spun yarn roller 100 generally does not rotate. At this time, the cleaning nozzle 31 set above the conveyor belt 2 can only spray to a part of the roller skin 102. At this time, the wetting and moistening degree of the roller is not thorough, which affects the cleaning efficiency. In addition, as the conveyor belt 2 runs, the spun yarn roller 100 is affected by the friction of the first set round brush and starts to rotate for cleaning. However, due to the large speed difference between the spun yarn roller 100 and the continuously running round brush, especially the part of the spun yarn roller 100 that is not wetted, the first set round brush wears faster, and the friction and jamming between them are also easy to affect the smooth operation of the conveyor belt 2. If the spray flow rate of the first set cleaning nozzle 31 is increased, and the roller skin 102 is rotated by spraying to deal with it, a large amount of wastewater is likely to be generated.

[0039] To solve this problem, in a preferred embodiment of the utility model, a synchronous belt 34 for driving a pressure roller shaft 33 and a round brush to rotate is arranged above the conveyor belt 2, and the pressure roller shaft 33 acts on the roller skin 102 of the spun yarn roller 100, and the rotation direction of the roller skin 102 of the spun yarn roller 100 is opposite to the rotation direction of the round brush. According to the forward direction of the spun yarn roller 100, the pressure roller shaft 33 is arranged before the cleaning nozzle 31 which is first arranged. Among them, the pressure roller shaft 33 and the synchronous belt 34 can be installed on the frame or on the cleaning baffle 23. Since the roving roller 100 is affected by the round brush and rotates during the forward movement, the rotation directions of the two are opposite. The utility model sets a pressure roller shaft 33 before the cleaning nozzle 31 that is first set. The pressure roller shaft 33 is driven by the synchronous belt 34 and the roller skin 102 that acts on the roving roller 100 rotates first. The roller skin 102 with residual rotation speed is wetted to a higher degree after being sprayed by the cleaning nozzle 31. Moreover, since the roller skin 102 already has a residual rotation speed in the opposite direction, the round brush is omitted from the process of accelerating the rotation of the roller skin 102 with an initial rotation speed of zero, thereby reducing unnecessary friction, which is beneficial to increasing the service life of the round brush that is first set, and also reducing the cleaning wear of the roving roller 100.

[0040] Among them, the cross-sectional shape of the pressure roller shaft 33 can be of different shapes, preferably circular, so that it can act on the roller skin 102 to rotate under the drive of the synchronous belt 34. The surface of the pressure roller shaft 33 can be made of a rough material, so that the roller skin 102 can be rotated by a slight contact with the roller skin 102. The degree of jamming during rotation acceleration is also lower than that of a round brush, and the durability is also higher.

[0041] In a specific embodiment of the utility model, a dust collecting device 35 is provided below the conveyor belt 2, and the dust collecting device 35 can be installed on a frame. The dust collecting device 35 can be specifically provided below the working surface of the conveyor belt 2. The fibers, hairs or dirt brushed out can be removed in time by the negative pressure dust collecting device 35. The round brush rotates at a fast speed and is maintained for a long time. The dust collecting device 35 is provided below the conveyor belt 2 to reduce the risk of fibers or hairs being entangled on the round brush, which is conducive to maintaining the cleaning efficiency of the round brush.

[0042] In a specific embodiment of the utility model, the entrance of the rolling feed channel 1 is connected to the outlet of the spiral vibrating screening disc 5 through the second conveyor belt 4, and the entrance channel baffles 41 are arranged on both sides of the second conveyor belt 4. The second conveyor belt 4 and the entrance channel baffles 41 can be installed on the frame. In the utility model, the spiral vibrating screening disc 5 can be used to select the position of the spun yarn rollers 100 that need to be cleaned by vibration, and the spun yarn rollers 100 are evenly arranged along the spiral track and transported to the rolling feed channel 1 through the second conveyor belt 4.

[0043] In a specific embodiment of the utility model, a workpiece support plate 6 is provided on one side of the conveyor belt 2 relative to the rolling feed channel 1, a material box 7 is provided below the workpiece support plate 6, compressed air nozzles 71 are provided around the material box 7, and a hollow mesh is provided on the bottom plate of the material box 7 (not shown in the figure). The workpiece support plate 6 can be installed on a frame. After cleaning, the roving roller 100 detaches from the gripper 21 and falls into the material box 7 through the workpiece support plate 6, so as to prevent the roving roller 100 that detaches from the gripper 21 from hitting the gripper 21 below. Figure 4 The direction of the arrow in the figure indicates the forward direction of the roving roller 100. The workpiece support plate 6 can be set in a slide shape, and the bottom surface of the front end of the workpiece support plate 6 can be provided with a second avoidance groove 61 for the gripper 21 to pass through. In this way, the workpiece support plate 6 can ensure that the fallen roving roller 100 is caught in time and sent into the material box 7 while facilitating the gripper 21 to pass through.

[0044] In the present invention, the rinsed roving roller 100 has moisture on it, and the compressed air nozzle 71 arranged around the material box 7 is used to spray the roving roller 100 that falls into the material box 7 to remove the residual moisture on the roving roller 100, and the moisture is discharged through the hollow mesh arranged on the bottom plate of the material box 7, so as to avoid rust on the roving roller 100 and affect the roving quality. Among them, the compressed air nozzle 71 can be controlled by an induction switch, and the compressed air nozzle 71 is turned on after sensing that the roving roller 100 falls into the material box 7.

[0045] The working principle of the automatic cleaning device for spun yarn rollers provided by the utility model is as follows: the spun yarn rollers 100 that need to be cleaned are poured into the spiral vibrating screening plate 5, and after starting, the spun yarn rollers 100 are arranged evenly and sent to the entrance of the rolling feed channel 1 through the second conveyor belt 4. The spun yarn rollers 100 are fed through the slide-shaped rolling feed channel 1. After the spun yarn rollers 100 roll down, under the action of the end blocking portion 12, they can be perpendicular to the forward direction of the spun yarn rollers 100 and maintain a horizontal horizontal setting. The "C"-shaped gripper on the starting section of the conveyor belt 2 passes through the avoidance groove 11 of the rolling feed channel 1, and at the same time, the roller shaft 101 in the middle of the spun yarn roller 100 stopped at the end of the rolling feed channel 1 is grabbed. The spun yarn rollers 100 are cleaned in the gripper 21 as the conveyor belt 2 runs, and first pass through the pressure roller shaft At 33, the roller skin 102 of the roving roller 100 rotates, and the cleaning nozzle 31 sprays cleaning agent and water to wet the roving roller 100, and then cleans it through the action of the round brush. During the cleaning process, the dust suction device 35 removes the pollutants brushed out. After passing through the last round brush, the rinsing device 32 sprays and washes away the cleaning agent remaining on the roving roller 100. Then, in the process of the roving roller 100 turning downward with the conveyor belt 2, the roving roller 100 separates from the "C"-shaped gripper under the action of gravity, and the roving roller 100 falls from the opening of the "C"-shaped gripper into the workpiece support plate 6, and then falls into the material box 7. The moisture on the roving roller 100 is removed by the compressed air nozzle 71 around the material box 7, and the moisture is discharged through the hollow mesh of the bottom plate of the material box 7 to complete the cleaning.

[0046] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description, and all these improvements and changes should fall within the protection scope of the present invention.
