Description

Technical Field

[0001] This application relates to the field of flatbed printing machines, and more particularly to a fabric feeding device for a flatbed printing machine. Background Technology

[0002] Rayon fabric, also known as viscose fiber fabric, is made from natural wood pulp through chemical processing. It combines the breathability and moisture absorption of natural fibers with the drape and crispness of chemical fibers, offering a soft, skin-friendly feel and vibrant colors. It is widely used in the production of various garments and home textiles. In the finishing stage of rayon fabric, flatbed printing machines are key equipment for imbuing it with a rich variety of patterns and colors. Flatbed screen printing machines are the core equipment for textile fabric printing. They transfer dye to the fabric surface through the perforated structure of the flatbed screen to form precise and clear printed patterns. They are widely used in the printing processing of cotton, linen, chemical fiber and other fabrics.

[0003] Regarding the aforementioned technologies, impurities often adhere to the surface of the fabric. When these impurities enter the flatbed printing machine along with the fabric, they tend to adhere to the openwork patterns on the flatbed screen, preventing the dye from penetrating properly and resulting in pattern defects such as "broken patterns" and "missing colors," which affect the printing quality. Utility Model Content

[0004] In order to reduce impurities on the fabric surface and improve printing quality, this application provides a fabric feeding device for a flatbed printing machine.

[0005] The fabric feeding device for a flatbed screen printing machine provided in this application adopts the following technical solution: A fabric feeding device for a flatbed printing machine includes a frame, a cleaning brush, and a dust collection component. The frame is used to connect to the printing machine body. The cleaning brush and the dust collection component are distributed at intervals along the fabric transport direction. The cleaning brush is used to brush away impurities on the fabric surface, and the dust collection component is used to remove impurities from the fabric surface.

[0006] By adopting the above technical solution, during use, the fabric first passes through the cleaning brush and the dust collection component along the transport direction. The cleaning brush physically removes impurities from the surface of the fabric. When the fabric passes through the dust collection component, the dust collection component removes impurities and stubborn residues, thereby minimizing the possibility of impurities entering the printing machine with the fabric, thus improving the printing quality.

[0007] Optionally, the cleaning brush has connecting blocks at both ends, the frame has two connecting slots, one end of the connecting slot has a connecting port for inserting the connecting blocks, each connecting block is inserted into the frame through the connecting slot, and the frame is connected to a locking component, the locking component is used to lock the connecting blocks in the connecting slot.

[0008] By adopting the above technical solution, when in use, the connecting block is inserted into the connecting slot to achieve quick positioning and installation of the cleaning brush. The locking component fixes the connecting block in the connecting slot, minimizing the risk of displacement of the cleaning brush due to vibration during operation. When disassembling the cleaning brush, the locking component unlocks the connecting block from the connecting slot, thereby improving the ease of disassembly and assembly of the cleaning brush.

[0009] Optionally, the locking assembly includes an opening / closing plate and a rotating component. The opening / closing plate is used to open or close the connection port. One end of the opening / closing plate is rotatably connected to the frame. The rotating component is used to drive the opening / closing plate to rotate and cause the opening / closing plate to cover or move away from the connection port.

[0010] By adopting the above technical solution, when in use, the rotating component drives the opening and closing plate to rotate and cover the connection port, which can prevent the connecting block from coming out of the connection groove. When it is necessary to disassemble the cleaning brush, the rotating component drives the opening and closing plate away from the connection port, and the connecting block can be removed. This facilitates the disassembly and assembly of the cleaning brush, and makes it easier to clean and replace the cleaning brush.

[0011] Optionally, the rotating component includes a mounting rod, a rotating rod, and a movable plate. The mounting rod is connected to one end of the opening and closing plate. The end of the mounting rod away from the closing plate is hinged to the rotating rod. The end of the rotating rod away from the mounting rod is hinged to the movable plate. The movable plate is slidably fitted to the frame. The cleaning brush is equipped with a driving component, which is used to drive the movable plate to move and drive the rotating rod and the opening and closing plate to rotate.

[0012] By adopting the above technical solution, when disassembling the cleaning brush, the driving component drives the moving plate to slide along the frame, the moving plate drives one end of the rotating rod, and then drives the mounting rod to rotate. The mounting rod drives the opening and closing plate to rotate around the rotation point, thereby facilitating the disassembly of the cleaning brush.

[0013] Optionally, the driving component includes a rotating shaft, a first gear, and a rack. There are two racks, each rack is connected to a moving plate, and the two racks are respectively located on both sides of the first gear. The first gear is connected to the rotating shaft, and the rotating shaft is rotatably connected to the frame. The racks mesh with the first gear.

[0014] By adopting the above technical solution, when in use, rotating the shaft drives the first gear to rotate, and the first gear simultaneously drives the racks on both sides to move in opposite directions synchronously, thereby driving the moving plates on both sides to slide synchronously, which facilitates the disassembly of the cleaning brush and improves work efficiency.

[0015] Optionally, the connecting block is connected to a first magnetic block, and the inner wall of the connecting groove is connected to a second magnetic block. When the connecting block approaches the inner wall of the connecting groove, the first magnetic block and the second magnetic block attract each other.

[0016] By adopting the above technical solution, when the connecting block is inserted into the connecting groove, the first magnetic block and the second magnetic block attract each other, so that the connecting block is stably connected to the inner wall of the connecting groove, minimizing the shaking caused by the gap when the cleaning brush is working. At the same time, the cleaning brush can be temporarily fixed in case the locking component fails, preventing it from falling out, thereby improving the installation reliability of the cleaning brush.

[0017] Optionally, the vacuuming assembly includes a vacuum hood and an air pump. The opening of the vacuum hood faces the fabric, and the vacuum hood is connected to an air extraction pipe. The other end of the air extraction pipe is connected to the air pump.

[0018] By adopting the above technical solution, when the fabric passes through the dust collection hood, the air pump starts to generate negative pressure, and the dust collection hood sucks in the impurities on the surface of the fabric through the opening, thereby further reducing the impurities on the surface of the fabric and improving the printing effect.

[0019] Optionally, a scraper is connected to one end of the dust hood near the fabric. One end of the scraper is used to contact the fabric and to guide impurities into the dust hood.

[0020] By adopting the above technical solution, when in use, the scraper contacts the fabric surface, scraping up stubborn impurities stuck in the gaps of the fabric texture, while confining the scraped impurities within the opening of the vacuum hood, making it easy for negative pressure to quickly remove them and improving the cleaning effect of the vacuum hood on the fabric.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the fabric first passes through the cleaning brush and the dust collection component along the transport direction. The cleaning brush physically removes impurities from the surface of the fabric. When the fabric passes through the dust collection component, the dust collection component removes impurities and stubborn residues, thereby minimizing the possibility of impurities entering the printing machine with the fabric, thus improving the printing quality. 2. When the fabric passes through the vacuum hood, the air pump starts to generate negative pressure. The vacuum hood sucks in impurities from the fabric surface through the opening, thereby further reducing impurities on the fabric surface and improving the printing effect. 3. When in use, insert the connecting block into the connecting slot to quickly position and install the cleaning brush. The locking component fixes the connecting block in the connecting slot to minimize displacement of the cleaning brush due to vibration during operation. When disassembling the cleaning brush, the locking component unlocks the connecting block from the connecting slot, thereby improving the ease of disassembly and assembly of the cleaning brush.

The depth of the connecting grooves 110 is aligned with the vertical direction, and one end of the connecting grooves 110 has a connecting port 111 for the connecting blocks 210 to pass through. Each connecting block 210 is inserted into the frame 100 through the connecting grooves 110. A first magnetic block 211 is embedded in the end of the connecting block 210 closest to the fabric, and a second magnetic block 112 is embedded in the inner wall of the connecting groove 110 closest to the fabric. When the connecting block 210 approaches the inner wall of the connecting groove 110, the first magnetic block 211 and the second magnetic block 112 attract each other.

[0032] Reference Figure 3 and Figure 4 A locking assembly 300 is provided on one side of the connecting slot 110. The locking assembly 300 includes an opening / closing plate 310 and a rotating member 320. One end of the opening / closing plate 310 is rotatably connected to the frame 100. In use, the opening / closing plate 310 covers the connecting port 111, and the rotating member 320 is used to drive the opening / closing plate 310 to rotate and drive the opening / closing plate 310 to cover or move away from the connecting port 111.

[0033] Reference Figure 3 and Figure 4 The rotating component 320 includes a mounting rod 321, a rotating rod 322, and a movable plate 323. The mounting rod 321 is connected to the end of the opening / closing plate 310 that connects to the frame 100. One end of the mounting rod 321 is fixedly connected to the opening / closing plate 310 along its length, and the other end of the mounting rod 321 is hinged to the rotating rod 322. The end of the rotating rod 322 away from the mounting rod 321 is hinged to the movable plate 323. The length direction of the movable plate 323 is consistent with the length direction of the cleaning brush 200, and the movable plate 323 slides along its length to engage with the frame 100. A driving component 400 is provided on the side of the cleaning brush 200 away from the fabric. The driving component 400 is connected to the frame 100 and is used to drive the movable plate 323 to move along its length. Two movable plates 323 on one cleaning brush 200 are driven by one driving component 400.

[0034] Reference Figure 1 and Figure 4The driving component 400 includes a rotating shaft 410, a first gear 420, and a rack 430. The length direction of the rotating shaft 410 is aligned with the vertical direction, and the rotating shaft 410 is rotatably connected to the frame 100. The first gear 420 is connected to the rotating shaft 410, and the central axis of the first gear 420 is collinear with the central axis of the rotating shaft 410. A handle 411 is connected to the end of the rotating shaft 410 away from the first gear 420. The first gear 420 is located between two movable plates 323. There are two racks 430, and the length direction of the racks 430 is aligned with the length direction of the cleaning brush 200. Each rack 430 is connected to a movable plate 323, and the two racks 430 are located on both sides of the first gear 420, and the racks 430 mesh with the first gear 420. When disassembling the cleaning brush 200, the rotating shaft 410 is rotated to drive the first gear 420 to rotate, which in turn drives the two racks 430 to move and drives the moving plate 323 to move. The moving plate 323 moves and drives the rotating rod 322 to move. The rotating rod 322 drives the mounting rod 321 and the opening and closing plate 310 to rotate, thereby facilitating the opening of the connection port 111 and facilitating the disassembly of the cleaning brush 200.

[0035] Reference Figure 1 and Figure 5 The frame 100 is connected to a dust collection assembly 500. The cleaning brush 200 and the dust collection assembly 500 are sequentially spaced along the fabric transport direction. The dust collection assembly 500 includes a dust collection hood 510 and an air pump 520. The length of the dust collection hood 510 is aligned with the width of the fabric. Two dust collection hoods 510 are provided, spaced vertically apart, with gaps between them for the fabric to pass through. The openings of the dust collection hoods 510 face the fabric. A scraper 511 is connected to the end of the dust collection hood 510 closest to the fabric, and the scraper 511 is located at the end of the dust collection hood 510 furthest from the cleaning brush 200. One end of the scraper 511 is connected to the dust collection hood 510, and the other end of the scraper 511 is inclined towards the cleaning brush 200.

A filter plate 531 is installed inside the collection box 530, vertically positioned, and its periphery is connected to the inner wall of the collection box 530. When the fabric passes through the dust collection hoods 510, the dust collection hoods 510 remove impurities from the fabric surface, thereby further reducing impurities and improving printing quality. The implementation principle of the fabric feeding device of a flatbed printing machine according to an embodiment of this application is as follows: During use, the fabric passes sequentially through the cleaning brush 200 and the dust suction component 500. The cleaning brush 200 and the dust suction component 500 clean the surface of the fabric, thereby reducing impurities on the fabric surface and improving the printing effect. When impurities adhere to the cleaning brush 200, the handle 411 is turned, thereby driving the rotating shaft 410 to rotate, and the first gear 420 follows the rotating shaft 410 to rotate. The first gear 420 drives the two racks 430 to move, and the moving plate 323 follows the racks 430 to move. The moving plate 323 drives the rotating rod 322 to move, and the rotating rod 322 drives the mounting rod 321 and the opening and closing plate 310 to rotate, thereby facilitating the opening of the connection port 111, thereby facilitating the removal of the connecting block 210 from the connecting groove 110, and facilitating the cleaning and replacement of the cleaning brush 200.
