DETAILED DESCRIPTION

[0050] In order to better understand the technical solutions, the technical solutions of the embodiments of the present application will be described in detail below through the figures and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0051] In the operation of the drawing frame 200, a large amount of flying dust 300 is generated, and when the flying dust 300 accumulates into a pile and falls into the sliver 400, yarn defects are formed. In order to avoid the formation of yarn defects, a cleaning device is usually provided for cleaning. The currently commonly used method requires the cleaning device to contact the roller, for example, a velvet belt, a steel rod, a scraper, etc. However, the above-mentioned contact cleaning method will cause wear of the cleaning device and the roller, reduce the service life of the cleaning device and the roller, and the friction between the cleaning device and the roller will generate heat, which is not easy to dissipate, affecting the normal operation of the roller. In order to solve the above problems.

[0052] As shown in Figures 1 to 6 , according to a first aspect of an embodiment of the present application, a roller structure 110 is provided, which comprises a roller; a cleaning assembly 120 located on the side of the roller, used to cause airflow changes at the surface of the roller to blow the flying dust 300 on the surface of the roller; and a dust suction assembly 130 used to suck the flying dust 300 blown by the cleaning assembly 120.

[0053] It can be understood that the cleaning device 100 provided by the embodiment of the present application is provided with a roller structure 110, a cleaning assembly 120 and a dust suction assembly 130. The roller structure 110 includes a roller, which holds the sliver 400 for processing. The cleaning assembly 120 is arranged on the side of the roller. When cleaning is performed, the cleaning assembly 120 can cause airflow changes at the surface of the roller, thereby blowing the flying dust 300 on the surface of the roller, avoiding the flying dust 300 from accumulating into a pile and falling into the sliver 400 to form yarn defects, and improving the quality of the sliver 400. Moreover, the cleaning assembly 120 only needs to cause airflow changes at the surface of the roller to make the flying dust 300 leave the surface of the roller, without the need for contact, thereby avoiding scratching between the cleaning assembly 120 and the roller, causing wear of the cleaning assembly 120 and the roller, and prolonging the service life of the cleaning assembly 120 and the roller. The dust suction assembly 130 is used to suck the flying dust 300 blown by the cleaning assembly 120, so as to collect the flying dust 300 and avoid the flying dust 300 from falling back, thereby improving the cleaning reliability.

[0054] It can be understood that the cleaning assembly 120 can cause the flow rate of the airflow at the surface of the roller to change, thereby forming a pressure difference at the surface of the roller to draw the flying dust 300 away from the surface of the roller and move with the airflow until the flying dust 300 is sucked into the dust suction assembly 130.

[0055] In some examples, as shown in Figure 1 , the cleaning assembly 120 comprises a cleaning piece located on the side of the roller, and a driving piece, the cleaning piece being connected to the driving piece, and the driving piece being used to drive the cleaning piece to cause airflow changes at the surface of the roller.

[0056] It can be understood that the cleaning assembly 120 is provided with a cleaning piece and a driving piece, wherein the cleaning piece is located at the peripheral side of the roller, and the driving piece drives the cleaning piece to cause the airflow at the surface of the roller to change, so as to form a pressure difference on the surface of the roller to pull the flying dust 300 away from the surface of the roller.

[0057] For example, the cleaning piece can be a fan structure, which can be installed at the peripheral side of the roller, such as the upper side, the lower side, or the left and right sides of the roller. The driving piece is a driving motor, and the fan structure is connected to the output shaft of the driving motor. The driving motor drives the fan structure to rotate, so as to blow the flying dust 300 away from the surface of the roller.

[0058] In some examples, as shown in Figures 3 to 6 The cleaning roller 121 includes a fixed piece 1211 connected to the roller structure 110, a fixed shaft 1212 fixedly connected to the fixed piece 1211, and a rotating piece 1213 arranged around the hub motor 122. When the hub motor 122 drives the rotating piece 1213 to rotate, the rotating piece 1213 causes the airflow at the surface of the roller to change.

[0059] It can be understood that the cleaning piece can be a cleaning roller 121. Specifically, the cleaning roller 121 is provided with a fixed piece 1211, a fixed shaft 1212, and a rotating piece 1213. The fixed piece 1211 can be fixedly connected to the roller structure 110, and the fixed piece 1211 is provided with a through hole through which the fixed shaft 1212 passes, and the fixed piece 1211 can limit the rotational freedom of the fixed shaft 1212. The driving piece can be a hub motor 122, which is sleeved on the fixed shaft 1212. The hub motor 122 and the fixed shaft 1212 do not rotate relative to each other, only the outer ring rotates, and the rotating piece 1213 is arranged around the hub motor 122. When the hub motor 122 drives the rotating piece 1213 to rotate, the rotation of the rotating piece 1213 can change the airflow speed at the surface of the roller, so as to pull the flying dust 300 away from the surface of the roller to clean the roller. The use of the hub motor 122 eliminates the need for additional transmission components such as belts and gears, and eliminates the need for the fixed shaft 1212 to rotate, thereby eliminating the need for additional bearings, simplifying the structure, and reducing maintenance difficulty and probability.

[0060] For example, the fixed piece 1211 can be a fixed block and a bolt, wherein the fixed block is provided with a through hole through which the fixed shaft 1212 passes, and the fixed block is provided with a threaded hole into which the bolt is screwed and abuts against the fixed shaft 1212 to limit the rotational freedom of the fixed shaft 1212.

[0061] In some examples, as shown inFigures 3 to 6 As shown, the rotating member 1213 is a rubber sleeve, and a plurality of protrusions are formed on the surface of the rubber sleeve, and recesses are formed between adjacent protrusions. Alternatively, the rotating member 1213 is a blade 1214.

[0062] It can be understood that the rotation of the rotating member 1213 can cause the airflow at the surface of the roller to change. The rotating member 1213 can be a rubber sleeve, and a plurality of protrusions can be formed on the surface of the rubber sleeve, and recesses can be formed between each two adjacent protrusions. When the rubber sleeve rotates, the airflow velocity at the surface of the roller can change, thereby attracting the fly dust 300 to separate from the surface of the roller. The rubber sleeve can be made of soft rubber material to avoid hard contact when the protrusions touch the roller, thereby preventing the rotating member 1213 and the roller from being damaged and improving the reliability. The rotating member 1213 can also be a blade 1214. A plurality of blades 1214 are distributed at intervals on the outer side of the hub motor 122. When the hub motor 122 rotates, the blades 1214 can be driven to rotate, thereby causing the airflow velocity at the surface of the roller to change, thereby attracting the fly dust 300 to separate from the surface of the roller.

[0063] For example, the plurality of blades 1214 can be connected by a rubber sleeve, and the rubber sleeve can be sleeved on the hub motor 122. Alternatively, the plurality of blades 1214 can be bonded to the outer side of the hub motor 122 by means of adhesive. The blades 1214 or the protrusions can be arranged in the form of inclined threads.

[0064] In some examples, the cleaning device 100 further includes a rotating speed detection member for detecting the rotating speed information of the hub motor 122, and a controller connected to the rotating speed detection member and the hub motor 122, respectively, for adjusting the rotating speed of the hub motor 122 to be within a desired rotating speed range according to the rotating speed information of the hub motor 122 sent by the rotating speed detection member.

[0065] It can be understood that the cleaning device 100 further includes a rotating speed detection member and a controller. The rotating speed detection member is used to detect the rotating speed information of the hub motor 122, and the controller can be electrically connected to the rotating speed detection member and the hub motor 122, respectively. When the cleaning device 100 performs cleaning work, the hub motor 122 rotates, and the rotating speed information of the hub motor 122 detected by the rotating speed detection member is sent to the controller. The controller adjusts the rotating speed of the hub motor 122 according to the rotating speed information, so that the rotating speed is within a desired rotating speed range. This avoids the rotating speed of the hub motor 122 being too slow, which cannot blow all the fly dust 300 on the surface of the roller, and also avoids the rotating speed of the hub motor 122 being too fast, which blows the cotton strip 400 on the roller, thereby affecting the normal work of the roller. This ensures that the rotating member 1213 can stably and reliably blow the fly dust 300 on the surface of the roller.

[0066] The wheel hub motor 122 can be controlled to adjust the speed and run at a constant speed after the speed is adjusted. The wheel hub motor 122 can be a direct current motor, which can be controlled by a programmable logic controller (PLC) analog module. The alternating current motor can be controlled by a PLC frequency converter or a servo driver. The controller can also be provided with a touch screen, which can display the current speed of the wheel hub motor 122 and other operating parameters. The cleaning assembly 120 can be automatically operated or controlled by the staff. The staff can click the control button of the touch screen to adjust the speed of the wheel hub motor 122 and the operation of the dust suction assembly 130. The synchronous operation of the cleaning assembly 120 and the dust suction assembly 130 can ensure that the flying dust 300 blown up by the cleaning assembly 120 can be sucked into the dust suction assembly 130 in time, thereby ensuring the cleaning reliability.

[0067] In some examples, the cleaning member is a pipe body, the pipe body is arranged on the roller and connected to the dust suction assembly 130; and the driving member is a fan connected to the pipe body and used to suck the flying dust 300 on the surface of the roller into the dust suction assembly 130.

[0068] It can be understood that the cleaning member can be a pipe body, the length of the pipe body is greater than or equal to the length of the roller, so that the pipe body can be arranged on the roller, and the pipe body can be connected to the dust suction assembly 130. In this case, the driving member can be a fan, which can change the air flow speed of the pipe body to form a negative pressure on the surface of the roller, so as to suck the flying dust 300 on the surface of the roller into the dust suction assembly 130.

[0069] It can be understood that the specific cleaning member can be selected according to the actual production situation on site to ensure that the installation position of the cleaning member and the way of removing the flying dust 300 adapt to the production and improve the applicability.

[0070] In some examples, as shown in Figure 1 and Figure 2 The roller structure 110 includes a seat body 113, the roller includes a first roller 111 and a second roller 112, the first roller 111 and the second roller 112 are both rotationally connected to the seat body 113, the first roller 111 is located above the second roller 112, and the first roller 111 and the second roller 112 cooperate to clamp the cotton strip 400; and a rocker 114 connected to the seat body 113 and used to abut against the first roller 111 to apply pressure to the roller.

[0071] It can be understood that the roller structure 110 is further provided with a seat body 113 and a rocker 114. Specifically, the roller is provided with a first roller 111 and a second roller 112, and the first roller 111 is located above the second roller 112. The first roller 111 and the second roller 112 are matched with each other to clamp the sliver 400, and the first roller 111 and the second roller 112 rotate synchronously to pull the sliver 400, improve the internal structure of the sliver 400, improve the long piece uniformity of the sliver 400, reduce the weight unevenness, straighten the fibers of the sliver 400, and reduce the hook. The first roller 111 and the second roller 112 are rotatably connected to the seat body 113, and the seat body 113 plays a supporting role. The rocker 114 is connected to the seat body 113 and located above the first roller 111. It can move towards the first roller 111. In the case that the pressure of the first roller 111 and the second roller 112 on the sliver 400 is lower than the ideal pressure range, the rocker 114 can be adjusted to abut against the first roller 111 and apply pressure to the first roller 111, thereby increasing the pressure on the sliver 400, so that the pressure falls within the ideal pressure range. In the case that the pressure of the first roller 111 and the second roller 112 on the sliver 400 exceeds the ideal pressure range, the rocker 114 can be adjusted to move away from the first roller 111 to reduce the pressure on the sliver 400, so that the pressure falls within the ideal pressure range.

[0072] It can be understood that the number of the first roller 111 and the second roller 112 can be multiple. Specifically, the number and position of the first roller 111 and the second roller 112 can be determined according to the pulling route of the sliver 400. For example, when the number of the first roller 111 and the second roller 112 is equal, and the position of the first roller 111 and the second roller 112 is relative, the sliver 400 can be clamped in the same plane, and the sliver 400 can be pulled in a straight line. When the number of the first roller 111 and the second roller 112 is different, the sliver 400 can be pulled in a curve, and additional friction is generated, thereby improving the control of the fiber movement of the sliver 400. At the same time, the number and position of the cleaning member can be determined according to the specific roller arrangement mode to meet various production modes and improve the applicability.

[0073] In some examples, as shown in Figure 1 and Figure 2 The dust suction assembly 130 includes a first dust suction pipeline 131 arranged at the top of the first roller 111, a second dust suction pipeline 132 arranged at the bottom of the second roller 112, a box body 133, the first dust suction pipeline 131 and the second dust suction pipeline 132 are connected to the box body 133 respectively, and a vacuum pump 134 arranged in the box body 133 is used to form negative pressure in the first dust suction pipeline 131 and the second dust suction pipeline 132.

[0074] It can be understood that the dust suction assembly 130 is provided with a first dust suction pipeline 131, a second dust suction pipeline 132, a box 133 and a vacuum pump 134. The first dust suction pipeline 131 and the second dust suction pipeline 132 are both communicated with the box 133, and the first dust suction pipeline 131 is arranged at the top of the first roller 111 to suck the flying dust 300 separated from the surface of the first roller 111 under the action of the cleaning piece into the box 133 for collection. The second dust suction pipeline 132 is arranged at the bottom of the second roller 112 to suck the flying dust 300 separated from the surface of the second roller 112 under the action of the cleaning piece into the box 133 for collection. The flying dust 300 is prevented from falling back to the first roller 111 or the second roller 112 to affect the processing of the cotton strip 400 and improve the reliability. The vacuum pump 134 can be arranged in the box 133 to form a negative pressure environment for the first dust suction pipeline 131 and the second dust suction pipeline 132 to provide power for the suction of the flying dust 300.

[0075] For example, a dust collection bag can be arranged in the box 133, and the flying dust 300 sucked in through the first dust suction pipeline 131 and the second dust suction pipeline 132 can fall into the dust collection bag. When the flying dust 300 in the dust collection bag is collected to a preset height, the dust collection bag can be taken out from the box 133 to process the flying dust 300 or replace a new dust collection bag, so as to facilitate the arrangement work.

[0076] In some examples, as shown in Figures 1 to 6 The cleaning piece includes a first cleaning piece and a second cleaning piece, wherein the first cleaning piece is connected to the cradle 114 and located between the first dust suction pipeline 131 and the first roller 111, and the second cleaning piece is connected to the seat body 113 and located between the second dust suction pipeline 132 and the second roller 112.

[0077] It can be understood that the cleaning piece can be provided with a first cleaning piece and a second cleaning piece. The first cleaning piece is connected to the cradle 114 to clean the flying dust 300 on the surface of the first roller 111, and the first cleaning piece is located between the first dust suction pipeline 131 and the first roller 111, so that the first dust suction pipeline 131 sucks in the flying dust 300 that is separated from the surface of the first roller 111 under the action of the first cleaning piece. The second cleaning piece is connected to the seat body 113 to clean the flying dust 300 on the surface of the second roller 112, and the second cleaning piece is located between the second dust suction pipeline 132 and the second roller 112, so that the second dust suction pipeline 132 sucks in the flying dust 300 that is separated from the surface of the second roller 112 under the action of the second cleaning piece. In this way, targeted cleaning work can be performed on the first roller 111 and the second roller 112, the reliability of removing the flying dust 300 is improved, and no additional installation position is required, the structure is simple, and the cost is reduced. Moreover, the lengths of the first dust suction pipeline 131 and the second dust suction pipeline 132 are reduced, the first dust suction pipeline 131 and the second dust suction pipeline 132 are prevented from interfering with the roller, and the layout is more reasonable.

[0078] It can be understood that the number of the first cleaning piece can be selected according to the number of the first roller 111, and the number of the second cleaning piece can be selected according to the number of the second roller 112, so as to ensure the cleaning effect. For example, the number of the first roller 111 is four, and the number of the first cleaning piece is three, so as to ensure that the flying dust 300 is removed from all the first rollers 111. The number of the second roller 112 is three, and the number of the second cleaning piece is three, so as to ensure that the flying dust 300 is removed from all the second rollers 112.

[0079] For example, the first cleaning piece and the second cleaning piece can both be a cleaning roller 121. Through rotation of the cleaning roller 121, the airflow velocity on the surface of the roller can be changed, so that the flying dust 300 is pulled away from the surface of the roller, thereby achieving cleaning of the roller. Moreover, the rotation directions of the cleaning rollers 121 are the same, so as to ensure the suction effect of the dust suction assembly 130 on the flying dust 300.

Therefore, the drawing frame 200 has all the beneficial effects of the cleaning device 100, which will not be described herein again.
