Description

Technical Field

[0001] This utility model belongs to the technical field of printing and dyeing equipment, and in particular relates to an overflow cylinder fabric discharge device for printing and dyeing. Background Technology

[0002] Dyeing and finishing, also known as printing and finishing, is a processing method that encompasses pretreatment, dyeing, printing, finishing, washing, and more. An overflow tank is an important device used in fabric dyeing environments. After dyeing and finishing, the fabric needs to be pulled out by a fabric ejection device. To prevent the removal of large amounts of dye and water, the fabric ejection device typically performs a squeezing and drainage operation.

[0003] Patent application CN201921179989.1 discloses an overflow cylinder fabric dispensing device for dyeing and printing, comprising a base plate, a fabric pressing box fixedly connected to the top left side of the base plate, a fixing frame fixedly connected to the top right side of the base plate, a rotating shaft fixedly connected inside the fabric pressing box, and a rotating cylinder fixedly connected to the outer surface of the rotating shaft. This utility model relates to the technical field of fabric dispensing devices for dyeing and printing. This overflow cylinder fabric dispensing device for dyeing and printing straightens the fabric using a first guide roller and a second guide roller. The rotation of the rotating shaft and the rotating cylinder drives the arc-shaped protrusion to rotate, causing the arc-shaped protrusion to squeeze the fabric. Combined with absorbent cotton, a connecting pipe, and a recycling box, excess dye moisture on the fabric surface is removed, effectively preventing dye and moisture from splashing or dripping onto the workshop floor. Simultaneously, keyways and key blocks are used to press the fabric, and sleeves and pressure blocks are used to fix the key blocks, quickly fixing and dispensing the fabric. The operation is simple and has high safety performance.

[0004] Existing technologies can use components such as wash cotton to shield and collect splashed dye, but there are still shortcomings: First, when the existing fabric extrusion device extrudes dye onto the fabric, the outer surface of the extrusion roller is prone to sticking with lint from the fabric surface. If the lint is not cleaned during the long-term extrusion process, it will easily affect the flatness of the outer surface of the extrusion roller, thereby affecting the extrusion operation of the extrusion roller on the fabric. At the same time, when extruding fabrics of different colors, it is easy to cause problems such as color bleeding. Secondly, when the fabric is pulled out from inside the overflow cylinder after dyeing, the fabric is not flat enough. If the fabric is not stretched and wrinkle-removed, the dye recovery rate will be low when the fabric is subsequently conveyed to the extrusion roller for the dye to be squeezed out. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this invention provides an overflow cylinder fabric discharge device for printing and dyeing. Through the arrangement of components such as a first scraper, a cleaning brush, and a second scraper, this invention can remove lint from the outer surface of the first extrusion roller while simultaneously tracking and removing lint from the outer circumference of the second extrusion roller without affecting its vertical position adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric discharge device for an overflow cylinder used in printing and dyeing, comprising a frame, wherein a first extrusion roller is rotatably arranged inside the frame, characterized in that a second extrusion roller is rotatably arranged above the first extrusion roller inside the frame, a first guide plate is obliquely arranged below the first extrusion roller inside the frame, a second scraper is arranged on one side of the first extrusion roller on the oblique end face of the first guide plate, the blade of the second scraper slides against the outer circular surface of the first extrusion roller, and a first L-shaped baffle is arranged on one side of the second extrusion roller inside the frame, a first scraper is fixedly arranged on the inner side wall of the first L-shaped baffle, the blade of the first scraper slides against the outer circular surface of the second extrusion roller.

[0007] Optionally, the second scraper has multiple first filter holes on its side wall near the first guide plate, and multiple third filter holes are provided at both ends of the first scraper near the inner side wall of the frame.

[0008] Optionally, sliding grooves are provided on both sides of the second extrusion roller on the side wall of the frame. A slider is slidably disposed inside each sliding groove. Each slider is rotatably connected to one end of its adjacent second extrusion roller. A threaded rod is rotatably connected to the upper end face of each slider. The top of each threaded rod passes through the frame and is threadedly connected to the side wall of the frame.

[0009] Optionally, connecting baffles are provided on both sides of the first L-shaped baffle, and each connecting baffle is fixedly connected to the upper end face of its adjacent slider.

[0010] Optionally, multiple cleaning brushes are provided on the adjacent end faces of the first L-shaped baffle and the vertical plate.

[0011] Optionally, a first guide roller is rotatably disposed on one side of the first extrusion roller inside the frame, a second guide roller is rotatably disposed between the first guide roller and the first extrusion roller inside the frame, two crossbars are disposed between the first guide roller and the second guide roller inside the frame, and multiple swing plates are rotatably disposed between the two crossbars.

[0012] Optionally, a wiper blade is rotatably arranged above the multiple swing plates inside the frame, the lower end of the wiper blade abuts against the outer circular surface of the second guide roller, a horizontal plate is arranged above the wiper blade inside the frame, and multiple elastic telescopic rods are rotatably connected between the wiper blade and the horizontal plate.

[0013] Optionally, the lower inclined surface of the wiper blade is provided with a plurality of guide grooves, and a water storage tank is fixedly provided below the plurality of guide grooves on the lower inclined surface of the wiper blade, and a plurality of second protrusions are provided on the lower end surface of the water storage tank.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) By setting up components such as the first scraper, the cleaning brush and the second scraper, this utility model can scrape off the lint on the outer surface of the first extrusion roller, and can also track and scrape off the lint on the outer surface of the second extrusion roller without affecting the vertical position adjustment of the second extrusion roller. It can also remove lint from the upper and lower surfaces of the fabric after extrusion, which can improve the water squeezing efficiency and avoid the problem of lint color bleeding, thus improving the production quality of the fabric. (2) By setting up components such as the swing plate, the squeegee and the second guide roller, this utility model can stretch and remove wrinkles from the fabric after it is pulled out by the overflow cylinder, so that when the fabric enters the first extrusion roller and the second extrusion roller for extrusion, the extrusion contact between the fabric and the first extrusion roller and the second extrusion roller is closer, thereby making the recovery rate of dye in the fabric higher.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1:

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, a fabric discharge device for an overflow cylinder used in printing and dyeing includes a frame 10. One side port of the frame 10 abuts against the fabric discharge port of the overflow cylinder, facilitating the return of the dye to the overflow cylinder during subsequent extrusion of the dyeing agent from the fabric. A first extrusion roller 11 is rotatably mounted inside the frame 10. An asynchronous motor is fixedly mounted on one side of the first extrusion roller 11 on the outer wall of the frame 10. The output end of the asynchronous motor passes through the frame 10 and is fixedly connected to one side of the first extrusion roller 11. A second extrusion roller 12 is rotatably mounted above the first extrusion roller 11 inside the frame 10. When the fabric is extruded, the fabric passes through the first extrusion roller. Between the first extrusion roller 11 and the second extrusion roller 12, the output end of the asynchronous motor drives the first extrusion roller 11 to rotate. The fabric is squeezed by the mutual movement between the first extrusion roller 11 and the second extrusion roller 12, and the fabric is transported horizontally. Excess dye contained in the fabric can also be squeezed out. Below the first extrusion roller 11, inside the frame 10, a first guide plate 13 is inclinedly arranged. Excess dye produced by the extrusion of the fabric by the first extrusion roller 11 and the second extrusion roller 12 drips onto the inclined end face of the first guide plate 13. The dye can be returned to the interior of the overflow tank by the inclined flow of the first guide plate 13.

[0019] Furthermore, such as Figure 3As shown, a second scraper 22 is provided on one side of the first extrusion roller 11 on the inclined end face of the first guide plate 13. The blade of the second scraper 22 slides against the outer circular surface of the first extrusion roller 11. With the second scraper 22 in place, when the first extrusion roller 11 rotates and extrudes the fabric, the blade of the second scraper 22 can scrape off the fabric lint adhering to the outer circular surface of the first extrusion roller 11. The lint and dye generated by scraping fall into the storage space formed by the frame 10, the first guide plate 13 and the second scraper 22, which is convenient for timely cleaning later. A first L-shaped baffle 17 is provided on one side of the second extrusion roller 12 inside the frame 10. A first scraper 19 is fixedly provided on the inner wall of the first L-shaped baffle 17. The blade of the first scraper 19 slides against the outer surface of the second extrusion roller 12. The first scraper 19 can also scrape off the lint adhering to the outer surface when the second extrusion roller 12 rotates and extrudes the fabric. At the same time, the scraped lint and dye are stored in the storage space formed by the frame 10, the first scraper 19, and the first L-shaped baffle 17. Timely scraping off the lint and dye adhering to the outer surface of the first extrusion roller 11 and the second extrusion roller 12 can ensure the cleanliness of the outer surface of the first extrusion roller 11 and the second extrusion roller 12, improve the extrusion effect of the first extrusion roller 11 and the second extrusion roller 12 on the fabric, and also prevent lint of different colors from adhering to the end face of different colored fabrics, causing color bleeding, thereby effectively improving the quality of the output fabric.

[0020] Furthermore, such as Figure 3 and Figure 7 As shown, the second scraper 22 has multiple first filter holes 23 on its side wall near the first guide plate 13, and the first scraper 19 has multiple third filter holes 39 at both ends near the inner side wall of the frame 10. The third filter holes 39 can filter the excess dye contained in the lint scraped off by the first scraper 19 from the outer surface of the second extrusion roller 12, and the dye flows along the inner side wall of the frame 10 through the multiple third filter holes 39 to the space between the vertical plate 20 and the second scraper 22. Then, with the multiple first filter holes 23, the excess dye contained in the lint between the vertical plate 20 and the second scraper 22 is precipitated, filtered and discharged, further increasing the dye recovery rate.

[0021] Furthermore, such as Figure 3 and Figure 4As shown, sliding grooves 14 are provided on both sides of the second extrusion roller 12 on the side walls of the frame 10, and a slider 15 is slidably disposed inside each sliding groove 14. Each slider 15 is rotatably connected to one end of its adjacent second extrusion roller 12. When extruding fabrics of different thicknesses, the vertical sliding adjustment of the second extrusion roller 12 can be achieved by adjusting the sliding of each slider 15 within the sliding groove 14. This, in turn, allows for adjustment of the width of the extrusion gap between the first extrusion roller 11 and the second extrusion roller 12, increasing the overall adaptability of the fabric output device. Each slider 15 has a threaded rod 16 rotatably connected to its upper end. The top of each threaded rod 16 passes through the frame 10 and is threadedly connected to the side wall of the frame 10. The bottom of the threaded rod 16 is rotatably connected to the slider 15 via a rotating connecting clip. When the threaded rod 16 is rotated, the threaded connection between the threaded rod 16 and the side wall of the frame 10 allows the slider 15 to slide up and down within the sliding groove 14, making the vertical movement adjustment of the second extrusion roller 12 more convenient. It should be noted that stainless steel is chosen to prevent the threaded rod 16 from rusting and corroding, and a dust cover can be installed externally to prevent dust and pigment from adhering to the threaded surface.

[0022] Furthermore, such as Figure 3 As shown, connecting baffles 18 are connected to both sides of the first L-shaped baffle 17. Each connecting baffle 18 is fixedly connected to the upper surface of its adjacent slider 15. The connecting baffles 18 can form a connection and fixation between the first L-shaped baffle 17 and the slider 15, ensuring that the first scraper 19 inside the first L-shaped baffle 17 tracks and scrapes away the lint on the outer surface of the second extrusion roller 12. When the second extrusion roller 12 is vertically moved and adjusted, the first L-shaped baffle 17 and the first scraper 19 and other components can be synchronously adjusted. At the same time, the connecting baffles 18 can also form a sealing barrier on the sliding groove 14, preventing the dye squeezed out of the fabric by the first extrusion roller 11 and the second extrusion roller 12 from flowing out of the device through the sliding groove 14, thus improving the practicality of the device.

[0023] Furthermore, such as Figure 3 As shown, multiple cleaning brushes 21 are provided on the adjacent end faces of the first L-shaped baffle 17 and the vertical plate 20. The multiple cleaning brushes 21 can clean the lint on the upper and lower end faces of the fabric after the fabric is squeezed out. The lint generated during cleaning needs to be cleaned by workers at regular intervals, which effectively increases the quality of the fabric.

[0024] Furthermore, such as Figure 3 and Figure 6As shown, a first guide roller 26 is rotatably arranged inside the frame 10 on one side of the first extrusion roller 11. A second guide roller 38 is rotatably arranged inside the frame 10 between the first guide roller 26 and the first extrusion roller 11. The arrangement of the first guide roller 26 and the second guide roller 38 forms a guiding conveyor for the fabric, and also forms a horizontal support for the fabric between the first guide roller 26 and the second guide roller 38, which facilitates the subsequent stretching and wrinkle removal of the fabric.

[0025] Furthermore, such as Figure 3 and Figure 6 As shown, two crossbars 27 are arranged inside the frame 10 between the first guide roller 26 and the second guide roller 38. Multiple swing plates 28 are rotatably arranged between the two crossbars 27. The swing plates 28 are centered on the middle cross section of the crossbars 27. The swing plates 28 on both sides are evenly divided into two groups and rotate towards the inner side wall of their respective adjacent frames 10. Through the eccentric structure of the swing plates 28, a prying operation from the inside to the outside can be formed with the lower end face of the fabric during the rotation of the multiple swing plates 28. While stretching the fabric, it also shakes and removes excess dye on the fabric, improving the efficiency of the subsequent fabric entering between the first extrusion roller 11 and the second extrusion roller 12 for extrusion.

[0026] Furthermore, such as Figure 6 As shown, each swing plate 28 has multiple first protrusions 29 on one end of its arc surface. The multiple first protrusions 29 increase the efficiency of the swing plate 28 in moving the fabric to both sides, and at the same time improve the efficiency of stretching the fabric. Each swing plate 28 has a motor 30 fixedly installed on one side of the crossbar 27. The output end of each motor 30 passes through the crossbar 27 and is fixedly connected to the side wall of the swing plate 28 on one side. The motor 30 is a common servo motor, which is existing technology. The multiple motors 30 provide power for the rotation of the multiple swing plates 28. The exterior of the multiple motors 30 is detachably equipped with a waterproof cover 31 on the side wall of the crossbar 27. The multiple waterproof covers 31 form a sealed protection for the multiple motors 30, preventing the multiple motors 30 from coming into contact with the dye dripping during the fabric conveying process, which would cause damage to the motors 30.

[0027] Furthermore, such as Figure 1 and Figure 3As shown, a squeegee 32 is rotatably mounted above multiple swing plates 28 inside the frame 10. The lower end of the squeegee 32 abuts against the outer circular surface of the second guide roller 38. A horizontal plate 33 is mounted above the squeegee 32 inside the frame 10. Multiple elastic telescopic rods 34 are rotatably connected between the squeegee 32 and the horizontal plate 33. Through the elastic support of the inclined end face of the squeegee 32 by the multiple elastic telescopic rods 34, the bottom end of the squeegee 32 and the second guide roller 38 form a squeezing operation on the stretched fabric, thereby forming a squeezing and scraping treatment on the small wrinkles of the stretched fabric. At the same time, the setting of the guide groove 35 can also block the dyeing agent splashed when the multiple swing plates 28 move and shake the fabric, preventing the dyeing agent from splashing to the outside of the device and causing pollution, and increasing the dyeing agent recovery rate.

[0028] Furthermore, such as Figure 5 As shown, the inclined lower end face of the squeegee 32 is provided with multiple guide grooves 35. Below the multiple guide grooves 35, a water storage tank 36 is fixedly provided on the inclined lower end face of the squeegee 32. The multiple guide grooves 35 serve to guide the flow of dye adhering to the inclined lower end face of the squeegee 32. Together with the guide grooves 35, they form a collection and storage of dye adhering to the inclined lower end face of the squeegee 32, preventing the dye from dripping back onto the upper end face of the fabric. At the same time, the lower end face of the water storage tank 36 can further improve the wrinkle removal effect on the stretched fabric by squeezing with the outer circular surface of the second guide roller 38. The lower end face of the water storage tank 36 is provided with multiple second protrusions 37. The multiple second protrusions 37 increase the squeezing area between the water storage tank 36 and the second guide roller 38, thereby improving the wrinkle removal effect of the second guide roller 38 and the water storage tank 36 on the fabric.
