Description

Technical Field

[0001] This application relates to the field of fabric production equipment, and in particular to a napping machine. Background Technology

[0002] In the textile fabric processing industry, napping machines are key equipment for achieving napping on the fabric surface, improving its feel and warmth, and playing an irreplaceable role, especially in the production of plush polyester blended elastic blankets. Plush polyester blended elastic blankets combine the softness and fluffiness of plush, the abrasion resistance and durability of polyester, and the easy recovery properties of elastic materials, making them a popular product in the market due to their excellent comprehensive performance.

[0003] Existing napping machines mainly include a frame, a drive unit, and a napping roller assembly. The surface of the napping roller is fixed with metal needle cloth or polymer bristles.

[0004] Regarding the aforementioned technologies, after prolonged use, lint tends to adhere to the surface of the lint roller. Typically, the lint on the surface of the lint roller is cleaned manually. However, the lint easily gets tangled in the bristles on the surface of the lint roller, making manual cleaning inconvenient and time-consuming, which in turn affects work efficiency. Utility Model Content

[0005] To facilitate the cleaning of lint from the rotating rollers and brush assembly and improve work efficiency, this application provides a lint-removing machine.

[0006] The brushing machine provided in this application adopts the following technical solution: A napping machine includes a frame with two rotating rollers connected to it. The two rotating rollers are spaced apart by a gap for fabric to pass through. Each rotating roller is connected to a rotating component that drives the rollers to rotate. An installation cavity is provided within each rotating roller. Several brush groups are connected to each rotating roller, each brush group including several first brushes. One end of each first brush is for contacting the fabric, and the other end of each first brush passes through the inner wall of the installation cavity. The first brushes are slidably connected to the rotating rollers. A moving component is provided within the installation cavity, which drives the first brushes to slide and connect to the rotating rollers and causes the outer wall of the rotating rollers to push the napping material away from the first brushes.

[0007] By adopting the above technical solution, during use, the rotating component drives the rotating roller to rotate, and the first brush pulls the fabric to create a rough texture. When the lint sticks to the first brush, the moving component drives the first brush to move along the rotating roller, causing the outer wall of the rotating roller to push the lint on the first brush away from the first brush. This makes it easier to manually clean the lint on the surface of the rotating roller, thereby reducing cleaning time and improving work efficiency.

[0008] Optionally, the moving component includes a connecting block and a pushing block. The connecting block is connected to the bristle assembly and slides along the length of the first brush to engage with the rotating roller. The pushing block slides along the length of the rotating roller to engage with the rotating roller. One end of the connecting block is provided with a first guide surface, which is used to guide the movement of the connecting block and adjust the length of the first brush outside the rotating roller. The first guide surface is in contact with the pushing block. One end of the connecting block and the pushing block are connected by a limiting member, which is used to prevent the connecting block from disengaging from the pushing block. The rotating roller is connected to a driving member, which is used to drive the pushing block to move and drive the pushing block to push the connecting block to slide and engage with the rotating roller.

[0009] By adopting the above technical solution, during the brushing process, the first brush is located outside the rotating roller. When the first brush is covered with lint, the driving component drives the pushing block to move along the length direction of the rotating roller. The pushing block contacts the first guide surface of the connecting block. Guided by the first guide surface, the pushing block pushes the connecting block to slide along the length direction of the first brush inside the rotating roller, thereby causing the first brush to slide along the length direction of the first brush inside the rotating roller. This reduces the length of the first brush outside the rotating roller, thereby causing the outer wall of the rotating roller to push the lint on the surface of the first brush, thus facilitating the cleaning of the first brush.

[0010] Optionally, the limiting component is a dovetail block, which is connected to the side of the connecting block with a first guide surface. The length direction of the dovetail block is consistent with the extension direction of the first guide surface. The pushing block has a dovetail groove on the side near the connecting block. The depth direction of the dovetail groove is consistent with the length direction of the dovetail block. The dovetail block slides and fits in the dovetail groove.

[0011] By adopting the above technical solution, during use, the dovetail block slides in the dovetail groove, thereby minimizing the cavity where the connecting block and the pushing block separate, and enabling the connecting block to move stably in a predetermined direction.

[0012] Optionally, a movable block is connected to one end of the rotating roller, and the frame has a movable hole. The movable block slides into the movable hole, and a drive assembly is connected inside the movable hole. The drive assembly is used to drive the two movable blocks to move and adjust the distance between the two rotating rollers.

[0013] By adopting the above technical solution, when the thickness of the fabric being brushed is different, the drive component drives the moving block to move, thereby adjusting the distance between the two rotating rollers to adapt to fabrics of different thicknesses and improve the applicability of the brushing machine to different fabrics.

[0014] Optionally, the drive assembly includes a threaded rod and a first motor. The threaded rod is rotatably connected to the moving hole, and the output shaft of the first motor is connected to one end of the threaded rod. The threaded rod includes a positive thread section and a negative thread section. One of the moving blocks is threaded onto the positive thread section, and the other moving block is threaded onto the negative thread section.

[0015] By adopting the above technical solution, the first motor drives the threaded rod to rotate, thereby causing the moving block to slide and fit into the moving hole, and driving the two moving blocks to move closer or further away from each other, thereby adjusting the distance between the two rotating rollers to adapt to fabrics of different thicknesses.

[0016] Optionally, the movable block is connected to a dust suction hood, the opening of which faces the rotating roller, and the dust suction hood is connected to an air pump.

[0017] By adopting the above technical solution, when the brushing machine is working, the air pump starts to generate suction from the dust hood, which can remove impurities such as lint and dust generated during the brushing process near the rotating roller, reducing the impact of impurities on the brushing effect and equipment operation.

[0018] Optionally, the dust hood is rotatably connected to a guide plate, one end of which is used to contact the rotating roller. The guide plate is used to guide lint into the dust hood. The dust hood is connected to a rotating assembly, which is used to drive the guide plate to rotate and move the guide plate away from the rotating roller.

[0019] By adopting the above technical solution, when cleaning lint, the moving component drives the first brush to move and embed the first brush into the rotating roller. The rotating component drives the guide plate to rotate, so that one end of the guide plate is attached to the surface of the rotating roller. When the rotating component drives the rotating roller to rotate, the lint on the surface of the rotating roller is guided to the opening of the dust collection hood, improving the lint collection efficiency. After cleaning is completed, the rotating component drives the guide plate to rotate and drives the guide plate away from the rotating roller, thereby minimizing interference between the guide plate and the first brush.

[0020] Optionally, the rotating assembly includes a first cylinder, a connecting rod, and a rotating rod. The first cylinder is connected to the dust collection hood. One end of the connecting rod is hinged to the piston rod of the first cylinder, and the other end of the connecting rod is hinged to one end of the rotating rod. The other end of the rotating rod is connected to a guide plate.

[0021] By adopting the above technical solution, the piston rod of the first cylinder extends and retracts, driving the connecting rod to move. The connecting rod drives the rotating rod to rotate, and the rotating rod drives the guide plate to rotate. No manual operation is required, further saving operation time and improving work efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. In use, the rotating component drives the rotating roller to rotate, and the first brush pulls the fabric to create a rough texture. When the lint sticks to the first brush, the moving component drives the first brush to move along the rotating roller, so that the outer wall of the rotating roller pushes the lint on the first brush away from the first brush. This makes it easier to manually clean the lint on the surface of the rotating roller, thereby reducing cleaning time and improving work efficiency. 2. When the first brush is covered with lint, the driving component drives the pushing block to move along the length of the rotating roller. The pushing block contacts the first guide surface of the connecting block. Guided by the first guide surface, the pushing block pushes the connecting block to slide along the length of the first brush inside the rotating roller, thereby driving the first brush to slide along the length of the first brush inside the rotating roller, which facilitates the cleaning of the first brush. 3. The first motor drives the threaded rod to rotate, which in turn drives the moving block to slide and fit into the moving hole, and drives the two moving blocks to move closer or further apart, thereby adjusting the distance between the two rotating rollers to accommodate fabrics of different thicknesses.

[0037] Reference Figure 2 and Figure 3A driving component is connected to the rotating roller 200, which drives the pushing blocks 420 to move along the length of the rotating roller 200. The driving component is a second cylinder 600, which is connected to one end of the rotating roller 200. The length of the second cylinder 600 is aligned with the length of the rotating roller 200, and the piston rod of the second cylinder 600 passes through the inner wall of one end of the mounting cavity 230. The piston rod of the second cylinder 600 is connected to a moving rod 610, which is aligned with the length of the rotating roller 200. The second cylinder 600 drives the moving rod 610 to slide and engage with the mounting cavity 230 along the length of the rotating roller 200. Several pushing blocks 420 are connected to the periphery of the moving rod 610, and the pushing blocks 420 are distributed at equal angular intervals along the circumference of the rotating roller 200 on the moving rod 610. During roughening, the connecting block 410 is located at the end of the pushing block 420 away from the moving rod 610. The second cylinder 600 drives the moving rod 610 to move, which causes the pushing block 420 to push the connecting block 410 to move, thereby causing the first brush 320 to move radially along the rotating roller 200, thus facilitating the cleaning of lint.

[0040] The implementation principle of a napping machine according to an embodiment of this application is as follows: a second motor 220 drives a rotating roller 200 to rotate, causing the brush assembly 300 to nap the fabric. When faced with different napping depth requirements for different fabrics, a second cylinder 600 drives a moving rod 610 to move along the length of the rotating roller 200. A pushing block 420 moves along the moving rod 610, pushing the connecting block 410. Guided by the first guide surface 411, the connecting block 410 moves along the length of the first brush 320. At the same time, a dovetail block 412 slides and engages in the dovetail groove 422. The connecting block 410 drives the mounting plate 310 to move, thereby changing the length of the first brush 320 outside the rotating roller 200, thus facilitating adaptation to the napping depth requirements of different fabrics.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
