Abstract
Description
Technical Field
[0001] This utility model relates to the field of brushing device technology, and more specifically, it relates to a brushing device for peach skin velvet. Background Technology
[0002] Peach skin fabric is a type of imitation leather fabric. The surface of the fabric has a layer of fluff, which is a short and dense layer of fluff formed on the surface of the fabric by a brushing device through mechanical friction.
[0003] Common napping devices include napping rollers and several drive rollers that move the fabric. Common materials for napping rollers include carbon fiber and corundum. However, the napping rollers usually cover the entire roller, resulting in the fabric being completely covered with fuzz after napping. Traditional napping devices cannot be used if only a section of the fabric needs to be napped, thus reducing the applicability of the napping device.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a peach skin velvet brushing device.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A peach skin velvet brushing device includes several conveying rollers and a brushing roller located between adjacent conveying rollers. Several brushing parts 1 and several brushing parts 2 are alternately arranged on the outer peripheral wall of the brushing roller. The brushing parts 2 are detachably connected to the outer peripheral wall of the brushing roller. The brushing parts 1 and 2 are respectively composed of several sandpaper 1 and several sandpaper 2. The grit of the several sandpaper 2 gradually decreases from the closer to the brushing roller to the farther away from the brushing roller. A sliding space is opened in the brushing roller. Several push rods that abut against the several sandpaper 2 are connected in the sliding space. Several sliding pieces are arranged on the outer peripheral wall of the conveying roller. The distance between the sliding pieces and the outer peripheral wall of the conveying roller is changed by telescopic members.
[0007] The present invention is further configured such that: a through hole is provided through the sandpaper 2 located in the middle layer and the innermost layer, and the push rod extends into the through hole to push out the outermost layer of sandpaper 2; a through hole is provided on the innermost layer of sandpaper 2, and the push rod extends into the through hole to push out the middle layer of sandpaper 2.
[0008] The present invention is further configured such that both ends of the first and second sandpapers are fixedly connected by Velcro, and the push rod abuts against the rough side of the second sandpaper with the Velcro fixed thereto.
[0009] The present invention is further configured such that: a locking block is fixedly connected to the bottom surface of a plurality of the push rods, and a locking groove for fixing the locking block is provided on the inner bottom surface of the grinding roller, wherein the frictional force between the locking block and the inner wall of the locking groove is greater than the centrifugal force when the grinding roller rotates.
[0010] The present invention is further configured such that: the telescopic component is an airbag, a plurality of sliding pieces are fixedly connected to the outer peripheral wall of the airbag, and an active space is provided between adjacent sliding pieces.
[0011] The present invention is further configured such that: a suction tube for changing the diameter of the airbag is provided inside the airbag, and the end of the suction tube away from the airbag is connected to an air compressor.
[0012] In summary, this utility model has the following beneficial effects: by using several detachably connected abrasive parts two, only abrasive part one on the abrasive roller can contact the fabric, allowing the fabric passing through the abrasive roller to form spaced strip-shaped nap, thereby increasing the applicability of the abrasive device. Since the grit of several sandpapers one and several sandpapers two is different, nap of different lengths can be formed on the fabric. When both sandpapers one and two are removed by one layer, the distance between the fabric and the abrasive roller will increase. At this time, the diameter of the conveyor roller can be reduced by reducing the gas in the airbag, and the distance between the fabric and the abrasive roller can be reduced by the action of the conveyor roller, ensuring stable contact between the fabric and abrasive parts one and two.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0019] A peach skin brushing device, such as Figures 1-4As shown, the device includes a conveyor roller 1 and a napping roller 2 located between adjacent conveyor rollers 1. Both conveyor rollers 1 and napping roller 2 are driven by a motor. Several sliding pieces 6 are provided on the outer peripheral wall of the conveyor roller 1. The distance between the sliding pieces 6 and the outer peripheral wall of the conveyor roller 1 is changed by a telescopic member 10. Fabric is transferred through adjacent conveyor rollers 1, and the fabric is wrapped around the sliding pieces 6. Therefore, changing the distance between the sliding pieces 6 and the outer peripheral wall of the conveyor roller 1 changes the distance between the fabric and the napping roller 2. The telescopic member 10 is configured as an airbag, and the sliding pieces 6 are fixedly connected to the outer peripheral wall of the airbag. Therefore, the fabric is transferred through the airbag. The contraction or expansion of the airbag can change the distance between the sliding plate 6 and the conveying roller 1. There is a space between adjacent sliding plates 6 so that when the airbag is contracted to its minimum diameter, the sides of the sliding plates 6 that are close to each other will not collide. The airbag is equipped with several suction tubes 11 for changing the diameter of the airbag. The end of the suction tube 11 away from the airbag is connected to an air compressor. The increase and decrease of the gas in the airbag is realized by the combination of the air compressor and the solenoid valve. That is, the air compressor provides the air source so that the gas can enter the airbag through the suction tube 11. Then, the solenoid valve is energized to start releasing gas to expel the air in the airbag.
[0020] The outer peripheral wall of the abrasive roller 2 is alternately provided with several abrasive parts 1 and several abrasive parts 2. The end faces of abrasive parts 1 and adjacent abrasive parts 2 abut each other to avoid the situation where the connection between abrasive parts 1 and abrasive parts 2 cannot contact the fabric. Several abrasive parts 2 are detachably connected to the outer peripheral wall of the abrasive roller 2. After removing the abrasive parts 2, the fabric passing through the abrasive roller 2 can only contact several abrasive parts 2, which can form spaced strip-shaped pile on the fabric. In actual use, the number of abrasive parts 2 fixed on the abrasive roller 2 can be increased or decreased as needed, thereby controlling the width of the strip-shaped pile formed on the fabric and ensuring the versatility of the device.
[0021] The first and second abrasive parts are each composed of several pieces of sandpaper 1 (3) and several pieces of sandpaper 2 (4). The two ends of sandpaper 1 (3) and sandpaper 2 (4) are fixed with Velcro. One end of sandpaper 1 (3) is concave downwards, while the other end is convex. The loop and hook sides of the Velcro are fixed to the top of the concave end and the bottom of the convex end, respectively. This increases the contact area at both ends of sandpaper 1 (3), ensuring fixing strength while keeping the surface of the rolled-up cylindrical sandpaper 1 (3) smooth and preventing it from bulging upwards due to the Velcro, thus ensuring full contact between sandpaper 1 (3) and the fabric. The grit of the sandpaper 1 (3) and sandpaper 2 (4) gradually decreases from the piece closer to the abrasive roller 2 to the piece farther away from the abrasive roller 2. Sandpaper 1 (3) and sandpaper 2 (4) in the same layer have the same grit, resulting in the same length of nap on the fabric, ensuring... To improve the quality of the napping, the higher the grit number of sandpaper 3, the smaller the abrasive grains on its surface. Using these small abrasive grains to scrape the fiber surface can create a fine nap on the fabric surface. Therefore, by changing sandpaper 3 and sandpaper 4 with different grit numbers, the desired napping effect can be achieved. After removing one layer of sandpaper 3 and sandpaper 4, the distance between the new layer of sandpaper 3 and sandpaper 4 and the fabric increases. If the thickness of sandpaper 3 is too large, the fabric may not be able to contact the new layer of sandpaper 3 and sandpaper 4. In this case, a portion of the gas in the airbag can be released through the solenoid valve, causing the sliding plate 6 to move the fabric, reducing the distance between the fabric and the napping roller 2. This reduces the time required to change the napping roller 2 and adjust the fabric height, thus increasing work efficiency.
[0022] The abrasive roller 2 has a sliding space inside, and a number of push rods 5 are connected within the sliding space to abut against a number of sandpapers 2 4. The number of push rods 5 is the same as the number of layers of sandpapers 2 4. If there are three layers of sandpapers 2 4 in the abrasive part 2, through holes 1 7 are simultaneously opened in the middle layer and the innermost layer of sandpapers 2 4, allowing one of the push rods 5 to extend into the through hole 1 7 and abut against the side of the sandpaper 2 4 with a protrusion. This allows the worker to apply a pushing force to one side of the sandpaper 2 4 through the push rod 5, causing the two ends of the sandpaper 2 4 to separate. The innermost layer of sandpapers 2 4 has a through hole 2, into which one of the push rods 5 can extend to separate the middle layer of sandpapers. The bottom surfaces of several push rods 5, which extend into different through holes 2 and 7, are connected. Therefore, pushing one push rod 5 can push out several sandpapers 2 4 on the sanding parts 2 at the same time, which speeds up the removal efficiency. Since the adjacent sandpapers 1 3 and sandpapers 2 4 are in contact with each other, and the surfaces of sandpapers 1 3 and sandpapers 2 4 are smooth, it is difficult to make the two ends of sandpaper 1 3 lose connection when sandpapers 1 3 and sandpapers 2 4 are in contact with each other. Therefore, after sandpapers 2 4 can be removed by pushing rod 5, the end face of sandpaper 1 3 will be exposed to the air. At this time, the worker can remove it along the end face of sandpaper 1 3.
[0023] Each of the push rods 5 has an integrally formed locking block 8 on its bottom surface. The inner bottom surface of the abrasive roller 2 has a locking groove 9 for fixing the locking block 8. When the sandpaper 2 4 does not need to be removed, the push rod 5 is fixed in the locking groove 9 by the locking block 8. At this time, the end of the push rod 5 away from the locking groove 9 still extends into the through hole 1 7 and through hole 2, but does not abut against the sandpaper 2 4. Since the friction between the outer peripheral wall of the locking block 8 and the inner wall of the locking groove 9 is greater than the centrifugal force when the abrasive roller 2 rotates, the locking block 8 will not come out of the locking groove 9 during the rotation of the abrasive roller 2. One end of the push rod 5 extends into the abrasive roller 2, which makes it convenient for the worker to apply a pushing force to make it slide upward. Since one end of the push rod 5 is located in the through hole 1 7 and through hole 2, the through hole 1 7 and through hole 2 can restrict and guide the movement direction of the push rod 5, so that the push rod 5 can stably apply a pushing force to one end of the sandpaper 2 4.
[0024] Working principle: When the entire fabric needs to be brushed, sandpaper 2 4 is not removed from the brushing roller 2, allowing several pieces of sandpaper 1 3 and several pieces of sandpaper 2 4 to fully contact the fabric and form a pile. During this process, the ejector rod 5 is fixed in the locking groove 9 by the locking block 8, preventing the ejector rod 5 from applying pushing force to the sandpaper 2 4 while the brushing roller 2 is rotating. If it is necessary to form spaced strips of pile on the fabric, the worker only needs to push the ejector rod 5, allowing the ejector rod 5 to apply force to the sandpaper 2 4. Apply a pushing force to one end to separate the two ends of sandpaper 2 4 and remove sandpaper 2 4. After removing sandpaper 2 4, the diameter of the abrasive part 2 is reduced, and the fabric cannot contact the abrasive part 2. Only the abrasive part 1 can form intermittent strip-shaped pile on the fabric. If it is necessary to change the length of the pile formed on the fabric, the outermost sandpaper 1 3 and sandpaper 2 4 can be removed at the same time. Then adjust the diameter of the air bladder on the conveyor roller 1 to make the conveyor roller 1 drive the fabric downward to ensure that the fabric contacts sandpaper 1 3 and sandpaper 2 4 again.
