Description

Technical Field

[0001] This invention relates to the field of printing machine technology, and in particular to a three-roller lint-removing device before printing. Background Technology

[0002] Fabric surfaces generally have residual lint or lint, especially after friction from the rollers of the fabric feeder or the splitting rollers, resulting in even more lint on the surface. During the printing process, this lint can easily clog the mesh openings, causing the printed area to show through and affecting the printing quality. Moreover, the lint on the fabric adheres to the guide belt, reducing its stickiness and increasing the frequency of peeling and applying adhesive to the printing guide belt, which not only wastes time, but also requires the use of a lint removal device to remove the lint from the fabric surface.

[0003] Existing technologies typically involve wrapping adhesive tape around the rollers of the printing machine to remove lint and fibers from the fabric. However, once the tape is covered with lint, its adhesion decreases significantly, requiring the tape to be cut and rewound. This process is not only time-consuming but also poses certain risks, such as the risk of hands getting caught in the rollers and sustaining injuries. Therefore, there is an urgent need for a lint removal device that uses three rollers before printing. Summary of the Invention

[0004] Based on the technical problems in the background art, the present invention proposes a three-roller lint removal device before printing.

[0005] This invention proposes a three-roller lint-removing device for printing, comprising: a main frame with two rotatable fixed frames; a lint-removing roller rotatably mounted on the fixed frames; the lint-removing roller includes: a fixed cylinder rotatably mounted on the fixed frames via a support member; a limiting plate fixed to the end of the fixed cylinder at its center; a docking frame fixed to the side of the limiting plate; a prism cylinder with its two ends nested and fixed to the two docking frames respectively; a rolling cylinder movably fitted around the prism cylinder; multiple sliding frames disposed on the inner wall of the rolling cylinder; multiple small bearings penetrating the prism cylinder; a friction disc rotatably mounted in the prism cylinder via the small bearings; a friction spring movably penetrating the two friction discs, the deformation length of the friction spring changing to automatically adjust the elastic force; two fixed plates fixed to the two ends of the friction spring respectively; and a central rod with its end fixed to the center of the fixed plate.

[0006] Preferably, the main frame has two bearing seats 1 on its side, and a brush roller is rotatably mounted between the two bearing seats 1 via a support member. Three bearing seats 2 are fixed to the sides of the two fixed frames, and a lint roller is rotatably mounted between the bearing seats 2 via a support member. An adhesive roller is rotatably mounted on the main frame.

[0007] Preferably, the bottom of the main frame is provided with a cleaning tank and a glue tank, and the main frame is provided with multiple connecting pipes, wherein the ends of two connecting pipes are respectively connected to a cleaning pump and a glue pump, and the ends of the other two connecting pipes are respectively connected to a glue cylinder and a cleaning cylinder.

[0008] Preferably, a glue spraying tube is fixedly installed through the main frame, a drive component one is fixedly installed on the side of the main frame, a drive component two is fixedly installed on the side of the main frame, the power output end of the drive component two is fixed to the end of the glue application roller, a reducer is fixedly installed on the side of the main frame, and a handwheel is fixed to the input end of the bottom of the reducer.

[0009] Preferably, the end of the connecting pipe is connected to the inside of the spray tube, wherein the ends of the two connecting pipes are respectively connected to the bottom of the cleaning tank and the glue tank, and the output end of the reducer is fixed to the middle of one of the fixing brackets.

[0010] Preferably, the lint roller, glue spray tube, brush roller and glue coating roller are parallel in axis, the glue spray tube is located above the glue coating roller, the brush roller is located directly below one of the lint rollers, and the glue coating roller is rotatably mounted on the main frame.

[0011] Preferably, the prism tube is in the shape of an equilateral octagon, the docking frame is in the shape of an equilateral octagon, the shape of the prism tube and the shape of the docking frame are matched, and the two ends of the prism tube abut against the two limiting plates.

[0012] Preferably, one side of the sliding frame has an opening with a sliding groove, the fixed plate rests against the sliding groove of the sliding frame, the other side of the sliding frame is arc-shaped to match the inner wall of the rolling cylinder, the included angle between the friction springs is 45°, and the friction springs pass through the two friction plates.

[0013] Preferably, the axial direction of the friction spring is perpendicular to the axial direction of the prism cylinder, the friction spring is movable through the prism cylinder, the axial direction of the prism cylinder and the axial direction of the friction spring are intersected, and the sliding frame surrounds the inside of the rolling cylinder.

[0014] Preferably, the friction disc has a spiral sliding hole in the opening, the friction spring spirally passes through the friction disc, the shape of the friction spring matches the sliding hole, and the friction disc surrounds the inside of the rolling cylinder.

[0015] The beneficial effects of this invention are as follows:

[0016] The glue spray nozzle sprays glue onto the coating roller. The glue is continuously sprayed onto the coating roller and the fabric, eliminating the need for frequent tape replacements. When the lint roller becomes too sticky due to excessive lint buildup, the printing worker rotates a handwheel to drive a reducer, which in turn rotates the three lint rollers. This causes the lint rollers to rotate to the cleaning station directly above the brush roller. The brush roller, driven by a drive unit, rotates, which in turn drives the lint roller to rotate, cleaning away impurities. During the rotation, one lint roller is always at each of the three stations, alternating between them. Residual glue on the coating roller falls into the glue tank and can then flow into the glue container for reuse, allowing for a cycle of application.

[0017] The friction spring spirally passes through the two friction discs, with the middle of the friction spring located inside the prism tube. The two ends of the friction spring are outside the prism tube and can be compressed to generate elastic force. When the ends of the friction spring are subjected to pressure, they deform to generate elastic force. The central rod moves with the rotation of the friction discs, while the friction spring slides spirally in the sliding hole of the friction discs, causing the friction discs to rotate in the middle of the small bearing. The position of the friction spring can be changed by changing the position of the friction discs, changing the length of the friction spring outside the prism tube, and changing the elastic force generated after the friction spring deforms. It can adaptively generate elastic force according to the pressure of the fabric on the rolling drum, and has the advantage of adaptive elastic force. Attached Figure Description

[0028] Reference Figures 1 to 9 A three-roller lint-removing device for printing includes: a main frame 1, on which two rotatable fixed frames 4 are provided; the fixed frames 4 are Y-shaped, and three lint-removing rollers 7 are rotatably arranged between the two fixed frames 4; the lint-removing rollers 7 are rotatably arranged on the fixed frames 4.

[0029] In this invention, the lint roller 7 includes: a fixed cylinder 71, which is rotatably mounted on a fixed frame 4 via a support member; the support member is a bearing member 72, which is a roller bearing that can be made by private customization or purchased on the market. The bearing member 72 is sleeved on the fixed cylinder 71 and is sleeved in the middle of the bearing seat 6, so that the fixed cylinder 71 can rotate in the middle of the bearing seat 6.

[0030] In this invention, a limiting disk 73 is fixed to the end of a fixing cylinder 71 in the middle; the fixing cylinder 71 is rotatably mounted in a fixing frame 4; a docking frame 74 is fixed to the side of the limiting disk 73; a prism cylinder 78 is nested and fixed at both ends to two docking frames 74 respectively; a rolling cylinder 76 is movably sleeved around the prism cylinder 78; the rolling cylinder 76 is located between the two limiting disks 73, and the rolling cylinder 76 can be misaligned with the limiting disks 73, so that the friction spring 711 slides in the friction disk 710.

[0031] In this invention, multiple sliding frames 77 are disposed on the inner wall of the rolling cylinder 76; the sliding frames 77 abut against the inner wall of the rolling cylinder 76; multiple small bearings 79 pass through the prism cylinder 78; a friction disc 710 is rotatably disposed in the prism cylinder 78 via the small bearings 79; the small bearings 79 can be obtained by purchasing from the market or by private customization, allowing the friction disc 710 to rotate in the prism cylinder 78; and a friction spring 711 is movably inserted through two friction springs. In the disc 710; when the friction disc 710 rotates, the friction spring 711 moves in the spiral sliding hole of the friction disc 710, which can change the deformation length of the friction spring 711. The deformation length of the friction spring 711 changes, and the elastic force is automatically adjusted; fixed disc 712, two fixed discs 712 are respectively fixed at both ends of the friction spring 711; center rod 75, the end of the center rod 75 is fixed in the middle of the fixed disc 712; the axis of the center rod 75 coincides with the axis of the two friction springs 711.

[0032] In this invention, two bearing seats 5 are provided on the side of the main frame 1. A brush roller 10 is rotatably provided between the two bearing seats 5 via a support member. The support member is a ball bearing and can be customized or purchased on the market. Three bearing seats 6 are fixed on the side of each of the two fixed frames 4. A lint roller 7 is rotatably provided between the multiple bearing seats 6 via a support member. The support member is a ball bearing and can be customized or purchased on the market, so that the lint roller 7 can rotate in the middle of the bearing seats 6.

[0033] In this invention, a cleaning tank 12 and an adhesive tank 13 are provided at the bottom of the main frame 1. A plurality of connecting pipes 14 are provided on the main frame 1. Two of the connecting pipes 14 are respectively connected to a cleaning pump 15 and an adhesive pump 16. The cleaning pump 15 delivers cleaning agent to the cleaning tank 12 through the connecting pipes 14. The adhesive pump 16 delivers adhesive to the spray pipe 9 through the connecting pipes 14. The bottom opening of the spray pipe 9 is provided with a nozzle. The adhesive is sprayed onto the fabric through the nozzle at the bottom of the spray pipe 9. The ends of the other two connecting pipes 14 are respectively connected to an adhesive cylinder 17 and a cleaning cylinder 18.

[0034] In this invention, a glue spraying tube 9 is fixedly installed through the main frame 1. A drive component 1 2 and a drive component 2 3 are fixedly installed on the side of the main frame 1. The drive components 1 2 and 2 3 are electric motors that can be purchased from the market or custom-made. The power output end of the drive component 1 2 is fixed to the brush roller 10, and the drive component 1 2 can drive the brush roller 10 to rotate. The power output end of the drive component 2 3 is fixed to the glue coating roller 11, so that the drive component 2 3 can drive the glue coating roller 11 to rotate. A reducer 19 is fixedly installed on the side of the main frame 1, and a handwheel 20 is fixed at the input end of the bottom of the reducer 19.

[0035] In this invention, the end of the connecting pipe 14 is connected to the inside of the spray pipe 9, and the ends of the two connecting pipes 14 are respectively connected to the bottom of the cleaning tank 12 and the glue tank 13. The output end of the reducer 19 is fixed in the middle of one of the fixing brackets 4. The handwheel 20 rotates to drive the input end of the reducer 19. The reducer 19 drives the lint roller 7 to rotate through the output end, and the lint roller 7 is applied to the lint roller.

[0036] In this invention, the axial directions of the lint roller 7, the glue spray tube 9, the brush roller 10, and the glue coating roller 11 are kept parallel. The glue spray tube 9 is located above the glue coating roller 11, and the brush roller 10 is located directly below one of the lint rollers 7. The glue coating roller 11 is rotatably mounted on the main frame 1. The printing worker rotates the handwheel 20 to drive the reducer 19 to rotate, thereby rotating the lint roller 7 and moving the lint roller 7 with glue to the lint-sticking station. When the lint roller 7 has too much lint attached and its stickiness decreases, the worker rotates the handwheel 20 to drive the reducer 19 to rotate, thereby rotating the lint roller 7 to the cleaning station. The brush roller 10 rotates under the drive of the drive component 2, and the brush roller 10 drives the lint roller 7 to rotate, cleaning away impurities and lint from the lint roller 7.

[0037] In this invention, the prism tube 78 is an equilateral octagon, and the docking frame 74 is an equilateral octagon. The shapes of the prism tube 78 and the docking frame 74 are matched. The two ends of the prism tube 78 abut against the two limiting plates 73. The docking frame 74 is inserted into the middle of the prism tube 78, fixing the docking frame 74 and the prism tube 78, so that the prism tube 78 is fixed between the two limiting plates 73, and the limiting plates 73, the docking frame 74 and the prism tube 78 rotate synchronously.

[0038] In this invention, a sliding groove is provided on one side of the sliding frame 77, and the fixed plate 712 abuts against the sliding groove of the sliding frame 77. The other side of the sliding frame 77 is arc-shaped and matches the inner wall of the rolling cylinder 76. Four friction springs 711 surround the sliding frame 77 with the axis as the center, and the included angle between the friction springs 711 is 45°. The friction springs 711 pass through the two friction plates 710. The fixed plate 712 can move in the sliding groove of the sliding frame 77, so that the rolling cylinder 76 can be directly fitted onto the eight sliding frames 77. The rolling cylinder 76 binds the eight sliding frames 77 to the outer periphery of the prism cylinder 78.

[0039] In this invention, the axial direction of the friction spring 711 is perpendicular to the axial direction of the prism cylinder 78. The friction spring 711 is movably inserted through the prism cylinder 78, and the axial direction of the prism cylinder 78 and the axial direction of the friction spring 711 are intersected. The sliding frame 77 surrounds the inside of the rolling cylinder 76. The friction disk 710 has an opening with a spiral sliding hole. The friction spring 711 spirally passes through the friction disk 710, and the shape of the friction spring 711 matches the sliding hole. The friction disk 710 surrounds the inside of the rolling cylinder 76 and can rotate on the prism cylinder 78 via a small bearing 79, allowing the friction spring 711 to pass through the prism cylinder 78. This prevents the friction spring 711 inside the prism cylinder 78 from being compressed by the two friction disks 710. Only the friction spring 711 located around the prism cylinder 78 can be compressed. The compressible length of the friction spring 711 can be changed, thereby adjusting the elastic force generated when the friction spring 711 deforms. The elastic force of the friction spring 711 can be adaptively adjusted. The central rod 75 moves through the middle of the friction disk 710. The friction spring 711, the central rod 75 and the fixed disk 712 are fixed. The friction disk 710 can slide on the central rod 75 to ensure that the friction disk 710 moves spirally along the axis of the central rod 75. When the friction disk 710 moves spirally along the friction spring 711, the friction disk 710 squeezes the friction spring 711 to produce deformation or bending, so that the direction of rotation of the friction disk 710 is always perpendicular to the axis of the friction spring 711.

[0040] In this invention, firstly, the device is placed in front of the printing host. The fabric passes through the printing machine and then passes around the glue coating roller 11 and the lint roller 7. The second drive component 3 drives the glue coating roller 11 to rotate. The rotation of the glue coating roller 11 causes the fabric to move on the lint roller 7. The glue pump 16 delivers glue into the glue spraying pipe 9 through the connecting pipe 14. The glue is sprayed onto the fabric and the glue coating roller 11 through the nozzle at the bottom of the glue spraying pipe 9, thus completing the glue coating station.

[0041] When removing lint, turn the handwheel 20. The handwheel 20 drives the reducer 19. The output end of the reducer 19 drives the fixed frame 4 to rotate, changing the position of the three lint rollers 7. One of the lint rollers 7 rotates to be directly above the brush roller 10. The cleaning pump 15 delivers the cleaning agent to the cleaning tank 12 through the connecting pipe 14. The drive component 2 drives the brush roller 10 to rotate. The brush roller 10 picks up the cleaning agent and rubs against the lint roller 7, brushing off the lint and cloth fibers from the surface of the lint roller 7.

[0042] In use, the fabric passes over the lint roller 7, causing it to rotate. The fabric passes over the rolling drum 76, and its pressure acts on the surface of the rolling drum 76. The position of the rolling drum 76 is misaligned with the prism cylinder 78. The pressure on the inner wall of the rolling drum 76 squeezes the friction spring 711. The friction spring 711 slides in the sliding hole of the two friction discs 710. During this process, the friction discs 710 move in the middle of the small bearing 79, and the position of the friction spring 711 changes relative to the prism cylinder 78. The length of the friction spring 711 extending out of the prism cylinder 78 changes, and the length of the friction spring 711 extending out of the prism cylinder 78 can deform. The elastic force generated by the friction spring 711 changes, thereby adaptively adjusting the elastic force of the friction spring 711 on the inner wall of the rolling drum 76, thus adjusting the pressure of the rolling drum 76 on the fabric.

[0043] The printing worker rotates the handwheel 20 to drive the reducer 19 to rotate the three lint rollers 7, moving the lint rollers 7 with glue to the lint-removing station. When the lint rollers 7 have too much lint and their stickiness decreases, the worker rotates the handwheel 20 to drive the reducer 19 to rotate the three lint rollers 7, moving them to the cleaning station. The brush roller 10 rotates under the drive of the drive component 2, driving the lint rollers 7 to rotate and cleaning the impurities off the lint rollers 7. During the rotation, one of the three lint rollers 7 will always be alternately positioned directly above the brush roller 10. The glue residue on the glue roller 11 falls into the glue tank 13 and can flow into the glue cylinder 17 for reuse, allowing for recycling.

[0044] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
