Description

Technical Field

[0001] This utility model relates to a processing device for printing and dyeing fabrics, belonging to the field of fabric printing and dyeing technology. Background Technology

[0002] In the textile printing and dyeing industry, uniform dyeing and processing efficiency are key indicators for measuring equipment performance.

[0003] To ensure the coloring effect, the dyeing solution is usually heated. The temperature of the dyeing solution determines the dyeing effect. Traditional dyeing equipment usually uses a static dyeing tank. The heating element in the dyeing tank is usually arranged at the bottom of the tank. This makes the temperature difference between the upper and lower layers of the dyeing solution large. The dyeing solution is prone to uneven dyeing due to uneven temperature distribution and dye precipitation, which affects the quality of the finished product.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a processing device for printing and dyeing fabrics. It solves the problem that in the prior art, traditional printing and dyeing equipment usually adopts a static dyeing tank, and the heating element in the dyeing tank is usually arranged at the bottom of the tank. This makes the temperature difference between the upper and lower layers of the printing and dyeing liquid large, and the printing and dyeing liquid is prone to uneven dyeing due to uneven temperature distribution and dye precipitation, which affects the quality of the finished product.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: A processing device for printing and dyeing fabric includes a dyeing box, with an inlet and an outlet for fabric communicating with the inside of the dyeing box on opposite sides. A fabric body is placed on the dyeing box, and a printing and dyeing liquid is placed inside the dyeing box. Two rotating shafts are rotatably connected to the inner walls of opposite sides of the dyeing box. Support arms are fixedly connected to the rotating shafts, and a support shaft is fixedly connected between the two support arms. A rotating cylinder is rotatably connected to the support shaft, and a support block is placed on the rotating cylinder. A support groove is opened through the support block, and the rotating cylinder passes through the support groove. Multiple water-spraying plates are placed on the support block. A driving mechanism is provided on the dyeing box, which can drive the support block to move up and down reciprocally. A dyeing mechanism is provided on the support block, which can spray the printing and dyeing liquid in the dyeing box onto the fabric body.

[0007] By adopting the above technical solution, when in use, the drive mechanism is activated, which drives the support block to move up and down reciprocally. During the up-and-down reciprocating movement of the support block, the water-dispensing plate is simultaneously driven to move up and down reciprocally. During the up-and-down movement of the water-dispensing plate, the dyeing liquid in the dyeing box is displaced up and down, thereby increasing the convection of the dyeing liquid in the dyeing box, increasing the uniformity of the dyeing liquid, so that the temperature of the dyeing liquid is uniform, reducing the temperature difference between the upper and lower layers of the dyeing liquid, and thus improving the dyeing effect on the fabric.

[0008] The present invention is further configured such that: multiple second rotating rods are rotatably connected between the inner walls of opposite sides of the dyeing box, and extrusion rollers are fixedly installed on the second rotating rods. The extrusion rollers are arranged in pairs. Multiple first rotating rods are rotatably connected between the inner walls of opposite sides of the dyeing box, and multiple guide rollers are fixedly installed on the first rotating rods.

[0009] By adopting the above technical solution, during use, the fabric body enters the dyeing box through the inlet, then passes between the corresponding paired guide rollers and squeeze rollers, and finally passes through the outlet through the outside of the dyeing box. The guide rollers guide the fabric body into the dyeing solution, while the fabric body is squeezed between the paired squeeze rollers, squeezing out the dyeing solution. On the one hand, after the fabric body is reintroduced into the dyeing solution, it can absorb more water again, thereby improving the uniformity of dyeing. On the other hand, the horizontal squeezing of the fabric body by the squeeze rollers facilitates the subsequent drying work after dyeing.

[0010] This utility model is further configured as follows: the driving mechanism includes a motor fixedly installed on one side of the dyeing box; one end of any rotating shaft away from the support block extends through the outside of the dyeing box and is poweredly connected to the output end of the motor; the ends of any two rotating shafts away from the support arm extend through the outside of the dyeing box and are each fixedly connected to a synchronous pulley; a synchronous belt drives between the two synchronous pulleys. Multiple fixing rods are fixedly connected to the support block; a connecting rod is fixedly connected to the end of each fixing rod away from the support block; multiple crossbars are fixedly connected to the connecting rods; a water-dispensing plate is fixedly connected to the end of each crossbar away from the connecting rod. Mounting blocks are fixedly connected to both ends of the connecting rods; multiple guide rods penetrating the mounting blocks are fixedly connected inside the dyeing box.

[0011] By adopting the above technical solution, when in use, starting the motor drives the rotating shaft connected to it to rotate. During the rotation of the rotating shaft, the support arm rotates axially. During the rotation of the support arm, the support shaft and the rotating cylinder rotate axially around the rotating shaft. During the axial rotation of the rotating cylinder around the rotating shaft, it slides in the support groove and drives the support block to move up and down. In turn, it drives the fixed rod fixed on the support block to move up and down. The fixed rod drives the connecting rod and the crossbar and water-dispensing plate fixed on the connecting rod to move up and down. During the up and down movement of the crossbar and water-dispensing plate, the dyeing liquor in the dyeing box is mixed, thereby improving the convection of the dyeing liquor, making the heating of the dyeing liquor more uniform, and improving the uniformity of the dyeing liquor. This improves the quality of the dyeing of the fabric and increases the practicality of the fabric processing device.

[0012] In this design, the guide rod slides through the mounting block to limit the movement of the connecting rod, ensuring that the connecting rod can only move up and down, preventing it from swaying in other directions, and thus improving the stability of the fabric printing and dyeing processing device.

[0013] The present invention is further configured as follows: the dyeing mechanism includes a fixed arm fixedly installed on the support block and on the side away from the fixed rod; two mounting shafts are rotatably connected to the inner walls of opposite sides of the dyeing box; a positioning tube is fixedly connected between the two mounting shafts; a sliding arm is fixedly connected to the positioning tube; a telescopic arm is slidably connected inside the sliding arm; the end of the telescopic arm away from the positioning tube extends through the sliding arm and is rotatably connected to the end of the fixed arm away from the support block; multiple nozzles are fixedly installed on the positioning tube; a fixed tube communicating with the inside of the positioning tube is fixedly connected to the positioning tube; the ends of any two mounting shafts extend through the outside of the dyeing box and are fixedly connected to a linkage gear; the two linkage gears are meshed together.

[0014] By adopting the above technical solution, a pump is installed inside the dyeing box. The pump is submerged in the dyeing solution, and a metal hose is fixedly connected to the pump's output end. The end of the metal hose away from the pump is fixedly connected to a fixed pipe, and the metal hose and the fixed pipe are internally connected. The positioning pipe, mounting shaft, and nozzle are all located above the surface of the dyeing solution. When the pump is started, it injects the dyeing solution from the dyeing box into the positioning pipe through the metal hose and the fixed pipe, and then sprays it onto the upper and lower surfaces of the fabric through the nozzle. This allows for a second dyeing of the upper and lower surfaces of the fabric, preventing incomplete dyeing and improving the uniformity of the dyeing process.

[0015] When the starter motor drives the support block to move up and down reciprocally, the support block simultaneously drives the fixed arm to move up and down reciprocally. During the up and down movement of the fixed arm, the telescopic arm and the sliding arm reciprocate axially around the mounting shaft. This process simultaneously drives the telescopic arm to slide within the sliding arm, and the sliding arm simultaneously drives the mounting shaft, positioning tube, and nozzle to rotate axially around the mounting shaft. The nozzle reciprocates to spray and dye the upper and lower surfaces of the fabric body, which can increase the dyeing range of the fabric body, thereby increasing the uniformity of the dyeing of the fabric body, and thus improving the dyeing quality of the fabric body. This, in turn, improves the processing quality of the fabric by the dyeing and printing equipment.

[0016] Furthermore, in this solution, a single motor can drive the nozzle to rotate back and forth to spray and dye the upper and lower surfaces of the fabric body. At the same time, it can also drive the water-repellent plate to move up and down to mix the dyeing liquid. This is more energy-efficient and increases the practicality and environmental friendliness of the dyed fabric.

[0017] The beneficial effects of this utility model are as follows: When the motor is started, it drives the rotating shaft connected to it to rotate. During the rotation of the rotating shaft, the support arm rotates axially. During the rotation of the support arm, the support shaft and the rotating cylinder rotate axially around the rotating shaft. During the axial rotation of the rotating cylinder around the rotating shaft, it slides in the support groove and drives the support block to move up and down. In turn, it drives the fixed rod fixed on the support block to move up and down. The fixed rod drives the connecting rod and the crossbar and water-dispensing plate fixed on the connecting rod to move up and down. During the up and down movement of the crossbar and water-dispensing plate, the dyeing liquor in the dyeing box is mixed, thereby improving the convection of the dyeing liquor, making the heating of the dyeing liquor more uniform, and improving the uniformity of the dyeing liquor. This improves the quality of the dyeing of the fabric and increases the practicality of the fabric processing device. Attached Figure Description

[0025] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following details... Figures 1 to 5 As shown, this utility model is further illustrated.

[0026] like Figures 1 to 3 As shown, this utility model is a processing device for printing and dyeing fabrics, including a dyeing box 1. The dyeing box 1 is hollow inside. An inlet 3 and an outlet 4, communicating with the interior of the dyeing box 1, are respectively opened on opposite sides of the dyeing box 1. A fabric body 5 is mounted on the dyeing box 1, and the fabric body 5 penetrates the dyeing box 1 through the inlet 3 and the outlet 4. A printing and dyeing solution is provided inside the dyeing box 1, covering the fabric body 5. Two rotating shafts 10 are rotatably connected to the inner walls of opposite sides of the dyeing box 1. Support arms 11 are fixedly connected to the rotating shafts 10, and a support shaft 1 is fixedly connected between the two support arms 11. 2. The support shaft 12 is fixedly connected to the end of the support arm 11 away from the rotating shaft 10. A rotating cylinder 13 is rotatably connected to the support shaft 12. A support block 14 is provided on the rotating cylinder 13. A support groove 15 is provided through the support block 14. The rotating cylinder 13 slides through the support groove 15. Multiple water-repelling plates 23 are provided on the support block 14. A driving mechanism is provided on the dyeing box 1. The driving mechanism can drive the support block 14 to move up and down reciprocally. A dyeing mechanism is provided on the support block 14. The dyeing mechanism can spray the dyeing liquid in the dyeing box 1 onto the fabric body 5.

[0027] When in use, the drive mechanism is activated, which drives the support block 14 to move up and down reciprocally. During the up and down reciprocating movement of the support block 14, the water-dispensing plate 23 is simultaneously driven to move up and down reciprocally. During the up and down movement of the water-dispensing plate 23, the dyeing liquid in the dyeing box 1 is displaced up and down, thereby increasing the convection of the dyeing liquid in the dyeing box 1, increasing the uniformity of the dyeing liquid, so that the temperature of the dyeing liquid is uniform, reducing the temperature difference between the upper and lower layers of the dyeing liquid, and thus improving the dyeing effect on the fabric.

[0028] like Figures 1 to 2 As shown, multiple second rotating rods 9 are rotatably connected between the inner walls of opposite sides of the dyeing box 1. Squeezing rollers 7 are fixedly installed on the second rotating rods 9. The squeezing rollers 7 are arranged in pairs. Multiple first rotating rods 8 are rotatably connected between the inner walls of opposite sides of the dyeing box 1. Multiple guide rollers 6 are fixedly installed on the first rotating rods 8. The guide rollers 6 are also arranged in pairs.

[0029] In use, the fabric body 5 enters the dyeing box 1 through the inlet 3, then passes between the corresponding paired guide rollers 6 and squeeze rollers 7, and finally passes through the outlet 4 through the outside of the dyeing box 1. The guide rollers 6 guide the fabric body 5 into the dyeing solution, while the fabric body 5 is squeezed between the paired squeeze rollers 7, squeezing out the dyeing solution. On the one hand, after the fabric body 5 is reintroduced into the dyeing solution, it can absorb more water again, thereby improving the uniformity of dyeing. On the other hand, the horizontal squeezing of the fabric body 5 by the squeeze rollers 7 facilitates the subsequent drying work after dyeing.

[0030] like Figures 4 to 5 As shown, the drive mechanism includes a motor 24 fixedly installed on one side of the dyeing box 1. One end of any rotating shaft 10 away from the support block 14 extends through the outside of the dyeing box 1 and is poweredly connected to the output end of the motor 24. The ends of any two rotating shafts 10 away from the support arm 11 extend through the outside of the dyeing box 1 and are fixedly connected to synchronous pulleys 17. A synchronous belt 18 is connected between the two synchronous pulleys 17. A support frame 2 for supporting the dyeing box 1 is fixedly connected to the lower side of the dyeing box 1.

[0031] like Figure 3 As shown, a plurality of fixing rods 16 are fixedly connected to the support block 14. A connecting rod 20 is fixedly connected to one end of the fixing rod 16 away from the support block 14. A plurality of crossbars 25 are fixedly connected to the connecting rod 20. A water-spraying plate 23 is fixedly connected to the end of the crossbar 25 away from the connecting rod 20.

[0032] like Figure 3 As shown, mounting blocks 21 are fixedly connected to both ends of the connecting rod 20, and multiple guide rods 22 that slide through the mounting blocks 21 are fixedly connected inside the dyeing box 1.

[0033] In this design, an installation cavity is provided between the lower surface and the bottom wall of the dyeing box 1. A heating component is installed inside the installation cavity. A temperature sensor is installed inside the dyeing box 1. A control panel is installed on the outside of the dyeing box 1. The control panel is electrically connected to the temperature sensor and the heating component. The heating component includes an electric heating wire, etc. The heating component is used to heat the dyeing solution inside the dyeing box 1.

[0034] In use, the motor 24 is started, which drives the rotating shaft 10 connected to it to rotate. During the rotation of the rotating shaft 10, the support arm 11 rotates axially. During the rotation of the support arm 11, the support shaft 12 and the rotating cylinder 13 rotate axially around the rotating shaft 10. During the axial rotation around the rotating shaft 10, the rotating cylinder 13 slides in the support groove 15 and drives the support block 14 to move up and down. In turn, it drives the fixed rod 16 fixed on the support block 14 to move up and down. The fixed rod 16 drives the connecting rod 20 and the crossbar 25 and the water-dispensing plate 23 fixed on the connecting rod 20 to move up and down. During the up and down movement of the crossbar 25 and the water-dispensing plate 23, the printing and dyeing liquor in the dyeing box 1 is mixed up and down, thereby improving the convection of the printing and dyeing liquor, making the heating of the printing and dyeing liquor more uniform, and improving the uniformity of the printing and dyeing liquor. This improves the printing and dyeing quality of the fabric body 5 and increases the practicality of the printing and dyeing fabric processing device.

[0035] In this design, the guide rod 22 slides through the mounting block 21 to limit the connecting rod 20, so that the connecting rod 20 can only move up and down, preventing the connecting rod 20 from shaking in other directions, thereby improving the stability of the fabric printing and dyeing processing device.

[0036] like Figures 2 to 4 As shown, the dyeing mechanism includes a fixed arm 28 fixedly installed on the support block 14 and on the side away from the fixed rod 16. Two mounting shafts 31 are rotatably connected to the inner walls of opposite sides of the dyeing box 1. A positioning tube 30 is fixedly connected between the two mounting shafts 31. A sliding arm 26 is fixedly connected to the positioning tube 30. A telescopic arm 27 is slidably connected inside the sliding arm 26. The end of the telescopic arm 27 away from the positioning tube 30 extends through the sliding arm 26 and is rotatably connected to the end of the fixed arm 28 away from the support block 14. Multiple nozzles 32 are fixedly installed on the positioning tube 30. The head 32 is internally connected to the positioning tube 30. A fixed tube 19, which is internally connected to the positioning tube 30, is fixedly connected to the positioning tube 30. The ends of any two mounting shafts 31 extend out of the outside of the dyeing box 1 and are fixedly connected to a linkage gear 29. The two linkage gears 29 are meshed together. A pump is installed inside the dyeing box 1. The pump is submerged in the dyeing solution. A metal hose is fixedly connected to the output end of the pump. The end of the metal hose away from the pump is fixedly connected to the fixed tube 19. The metal hose is internally connected to the fixed tube 19. The positioning tube 30, mounting shafts 31, and nozzle 32 are all located above the surface of the dyeing solution.

[0037] Start the pump, and the pump will inject the dyeing liquid in the dyeing box 1 into the positioning tube 30 through the metal hose and the fixed tube 19, and spray it on the upper and lower surfaces of the fabric body 5 through the nozzle 32, thereby re-dyeing the upper and lower surfaces of the fabric body 5. This can prevent the fabric body 5 from being dyed incompletely, thereby improving the uniformity of dyeing the fabric body 5.

[0038] When the starting motor 24 drives the support block 14 to move up and down reciprocally, the support block 14 simultaneously drives the fixed arm 28 to move up and down reciprocally. During the up and down movement of the fixed arm 28, the telescopic arm 27 and the sliding arm 26 reciprocate axially around the mounting shaft 31. During this process, the telescopic arm 27 slides within the sliding arm 26, and the sliding arm 26 simultaneously drives the mounting shaft 31, the positioning tube 30, and the nozzle 32 to rotate axially around the mounting shaft 31. The nozzle 32 reciprocates to spray and dye the upper and lower surfaces of the fabric body 5, which can increase the re-dyeing range of the fabric body 5, thereby improving the uniformity of dyeing the fabric body 5, and thus improving the dyeing quality of the fabric body 5, thereby improving the processing quality of the fabric by the dyeing and printing equipment.

[0039] Furthermore, in this solution, a single motor 24 can drive the nozzle 32 to reciprocate and spray the upper and lower surfaces of the fabric body 5 for printing and dyeing. At the same time, it can also drive the water-spraying plate 23 to move up and down to mix the printing and dyeing liquid. This is more energy-efficient and increases the practicality and environmental friendliness of the printed and dyed fabric.

[0040] In this design, the fabric body 5 is tensioned when it passes through the dyeing box 1, and the tension force on the fabric body 5 is relatively large. This prevents the fabric body 5 from violently swaying inside the dyeing box 1 during the up-and-down movement of the water-repelling plate 23.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
