Description

Technical Field

[0001] This utility model relates to the field of textile fabric production, specifically a desizing device for textile fabric production. Background Technology

[0002] Desizing refers to the removal of sizing agents (such as starch, polyvinyl alcohol PVA, carboxymethyl cellulose CMC, etc.) applied to textile fabrics during the weaving process through chemical, biological, or physical methods, in order to restore the fabric's softness and permeability. Textile desizing is an important step in textile processing, aiming to remove sizing agents (such as starch, PVA, etc.) added during the weaving process to facilitate subsequent dyeing, printing, and other processes.

[0003] In existing desizing processes for textile fabrics, decomposition products of the sizing agent, fiber debris, or other impurities may accumulate in the desizing solution, affecting the penetration and reaction of the desizing agent, resulting in turbidity and reduced desizing efficiency. Therefore, a new technical solution needs to be designed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a desizing device for textile fabric production. This device solves the technical problem that during the current desizing of textile fabrics, decomposition products of sizing agents, fiber debris or other impurities may accumulate in the desizing liquid, thereby affecting the penetration and reaction of the desizing agent, making the desizing liquid turbid and reducing the desizing efficiency.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a desizing device for textile fabric production, including a desizing box and a circulating filtration mechanism. The circulating filtration mechanism is set at the bottom of the desizing box. A partition is installed in the inner cavity of the desizing box. A perforation is opened on the partition. Guide rollers and cleaning rollers are respectively installed in the desizing box on both sides of the partition.

[0006] The circulating filtration mechanism includes two conduits installed inside the desizing tank and a filter box installed at the bottom of the desizing tank. The two conduits are respectively positioned on the upper and lower sides of the guide roller. One end of the filter box is connected to the bottom end of the desizing tank via an inlet pipe. One end of the inner cavity of the filter box is connected to a connecting pipe, and the other end of the connecting pipe is connected to a circulating pump. The outlet end of the circulating pump is connected to a circulating pipe, and the other end of the circulating pipe is connected to a U-shaped pipe. Both ends of the U-shaped pipe are connected to the two conduits. One end of each of the two conduits is connected to multiple nozzles. Filter plates are installed at an angle inside the filter box.

[0007] Preferably, a desizing agent inlet pipe is connected to the outside of the circulation pipe, and a desizing agent storage pipe is provided at one end of the desizing agent inlet pipe. A connecting flange is installed at one end of the desizing agent storage pipe and one end of the desizing agent inlet pipe. A piston is slidably connected to the inner cavity of the desizing agent storage pipe, and a cylinder is installed at the end of the desizing agent storage pipe away from the connecting flange. The driving end of the cylinder slides through the desizing agent storage pipe and is connected to the piston.

[0008] Preferably, the bottom of the filter box is provided with a discharge port, the bottom of the discharge port is connected to a rectangular discharge pipe, a feeding roller is rotatably connected to the rectangular discharge pipe through a rotating shaft, a storage trough is provided at both ends of the feeding roller, a drive motor is installed at one end of the outer side of the rectangular discharge pipe, the drive end of the drive motor is connected to the rotating shaft on the feeding roller, and a vibration motor is installed at the top of the filter box.

[0009] Preferably, a sealing gasket is connected to the outer side of the feeding roller. The sealing gasket is elastic and is arranged in contact with the inner wall of the rectangular discharge pipe.

[0010] Preferably, guide plates are inclinedly connected to both sides of the inner cavity of the discharge port, and the lowest ends of the two guide plates correspond to the two sides of the opening end of the storage tank, respectively.

[0011] Preferably, a one-way valve is installed in the desizing agent inlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a circulating pump, a filter box, a filter plate, a connecting pipe, an inlet pipe, a circulation pipe, a conduit, and a nozzle. By starting the circulating pump, the desizing agent and impurities generated during fabric desizing are drawn into the filter box. The filter plate then separates the desizing agent from the impurities. The filtered desizing agent is then sprayed into the desizing box through the nozzle, ensuring the cleanliness of the desizing agent within the box. This prevents the accumulation of sizing decomposition products, fiber debris, or other impurities in the desizing solution, which could affect the penetration and reaction of the desizing agent and reduce desizing efficiency. Simultaneously, the filtered desizing agent is sprayed out through the nozzle, allowing it to flow and circulate within the desizing box, thereby improving the effect and efficiency of desizing textile fabrics.

[0014] 2. This utility model combines a discharge port, a rectangular discharge pipe, a guide plate, a feeding roller, a drive motor, a vibration motor, a storage tank, and a sealing gasket. After the filter plate filters the desizing products, fiber debris, or other impurities in the desizing agent, the vibration motor is activated to drive the filter box and filter plate to vibrate. This vibration dislodges the desizing products, fiber debris, or other impurities adsorbed on the filter plate. The guide plate then guides the desizing products, fiber debris, or other impurities through the discharge port into the storage tank. The drive motor is then activated to rotate the feeding roller, causing the opening of the storage tank to face downwards, automatically discharging the desizing products, fiber debris, or other impurities from the filter box. Because the sealing gasket increases the sealing between the feeding roller and the inner wall of the rectangular discharge pipe, the desizing products, fiber debris, or other impurities can be discharged without stopping filtration, thereby improving the efficiency of the desizing agent filtration.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A desizing device for textile fabric production, see [link to example]. Figures 1 to 5The system includes a desizing tank 1 and a circulating filtration mechanism 2. The circulating filtration mechanism 2 is located at the bottom of the desizing tank 1. A partition 11 is installed inside the desizing tank 1, and a perforation 12 is formed on the partition 11. Guide rollers 14 and washing rollers 13 are respectively installed inside the desizing tank 1 on both sides of the partition 11. The circulating filtration mechanism 2 includes two conduits 27 installed inside the desizing tank 1 and a filter box 21 installed at the bottom of the desizing tank 1. The two conduits 27 are respectively placed on the upper and lower sides of the guide rollers 14. One end of the filter box 21 is connected to the bottom end of the desizing tank 1 by an inlet pipe 22. One end of the inner cavity of the filter box 21 is connected to a connecting pipe 24. The other end of the connecting pipe 24 is connected to a circulating pump 23. The outlet end of the circulating pump 23 is connected to a circulating pipe 25. The other end of the circulating pipe 25 is connected to a U-shaped pipe 26, and the U-shaped pipe 26... Both ends of the pipe 26 are connected to the two conduits 27 respectively. One end of each of the two conduits 27 is connected to multiple nozzles 28. The filter box 21 is installed at an angle with filter plates 29. During operation, the desizing agent in the desizing box 1 and the impurities generated during the desizing of the fabric are drawn into the filter box 21 by starting the circulation pump 23. Then, the desizing agent and impurities are separated by the filter plates 29. The filtered desizing agent is then sprayed into the desizing box 1 through the nozzles 28, thereby ensuring the cleanliness of the desizing agent in the desizing box 1. This avoids the accumulation of sizing decomposition products, fiber debris or other impurities in the desizing liquid, which may affect the penetration and reaction of the desizing agent and reduce the desizing efficiency. At the same time, the filtered desizing agent is sprayed out through the nozzles 28, allowing the desizing agent in the desizing box 1 to flow and circulate within the desizing box 1, thereby improving the effect and efficiency of desizing the textile fabric.

[0023] For details, see Figure 2 and Figure 4 The outer side of the circulation pipe 25 is connected to the desizing agent inlet pipe 4. One end of the desizing agent inlet pipe 4 is provided with a desizing agent storage pipe 42. Both the desizing agent storage pipe 42 and the desizing agent inlet pipe 4 are equipped with connecting flanges 45. The inner cavity of the desizing agent storage pipe 42 is slidably connected to a piston 43. The end of the desizing agent storage pipe 42 away from the connecting flange 45 is equipped with a cylinder 44. The driving end of the cylinder 44 slides through the desizing agent storage pipe 42 and is connected to the piston 43. A one-way valve 41 is installed in the desizing agent inlet pipe 4. When the desizing agent in the desizing tank 1 decreases or its concentration decreases, the desizing agent storage pipe 42, which stores the desizing agent, is connected to the desizing agent inlet pipe 4 through the connecting flange 45. Then, the cylinder 44 is activated to push the piston 43 to move, thereby pressurizing the one-way valve 41 to open and add the desizing agent into the desizing tank 1 along with the circulating desizing agent. This facilitates the replenishment of the desizing agent and ensures the desizing effect of the textile fabric.

[0024] Further, see Figure 3 and Figure 5The filter box 21 has a discharge port 36 at its bottom, and a rectangular discharge pipe 3 is connected to the bottom of the discharge port 36. A feed roller 32 is rotatably connected to the rectangular discharge pipe 3 via a rotating shaft. Both ends of the feed roller 32 have storage troughs 33. A drive motor 31 is installed at one end of the outer side of the rectangular discharge pipe 3, and the drive end of the drive motor 31 is connected to the rotating shaft on the feed roller 32. A vibration motor 210 is installed at the top of the filter box 21. A sealing gasket 34 is connected to the outer side of the feed roller 32. The sealing gasket 34 is elastic and is in contact with the inner wall of the rectangular discharge pipe 3. Guide plates 35 are inclinedly connected to both sides of the inner cavity of the discharge port 36. The lowest points of the two guide plates 35 correspond to the two sides of the opening end of the storage trough 33, respectively. When the filter plate 2 9. After filtering the desizing products, fiber debris, or other impurities in the desizing agent, the vibration motor 210 is started to drive the filter box 21 and filter plate 29 to vibrate. The desizing products, fiber debris, or other impurities adsorbed on the filter plate 29 are vibrated off the filter plate 29 and then passed through the guide plate 35 into the storage tank 33 through the discharge port 36. Then, the drive motor 31 is started to drive the feed roller 32 to rotate, and the opening of the storage tank 33 faces downward to automatically discharge the desizing products, fiber debris, or other impurities from the filter box 21. Since the sealing gasket 34 increases the sealing between the feed roller 32 and the inner wall of the rectangular discharge pipe 3, the desizing products, fiber debris, or other impurities can be discharged without stopping the filtration, thereby improving the filtration efficiency of the desizing agent.
