Technical Field

[0001] The invention relates to the technical field of fabric processing, in particular to a uniform sizing device and a sizing process for textile fabrics. Background Art

[0002] During the processing and production of textile fabrics, they are subject to high tension and friction, making them prone to breakage. To reduce warp breakage, improve weaving efficiency, and enhance the quality of the fabric, textile fabrics require sizing. Sizing enhances fiber adhesion and forms a strong film on the yarn surface, making the yarn dense and smooth.

[0003] In the prior art (publication number: CN118390257A), a sizing device is disclosed, specifically a uniform sizing device for textile fabrics, including a support frame, wherein the support frame is provided with two groups, a sizing roller is provided between the support frames, a first mounting plate is fixedly connected to one side of the support frame of one group, a motor is fixedly connected to the top of the first mounting plate, a rotating rod is fixedly connected to the output end of the motor, each feeding brush is evenly covered with raw material through a diverter box, and then the raw material is evenly applied to the sizing roller, and then scraped flat by a first coating plate and a second coating plate so that the raw material is evenly applied to the sizing roller, and finally uniformly sizing is performed by the sizing roller. Under this method, there is still a problem. At the beginning or end, because the sizing is not enough to fill the feeding brush, the feeding roller will not be evenly sizing.

[0018] As a further solution of the present invention: wherein, the spring coefficient of the return spring is smaller than the spring coefficient of the fixed spring.

[0019] As a further solution of the present invention: wherein, the blocking plate includes a flat plate parallel to the bottom of the material storage bin, a connecting plate embedded in the discharge hole is fixedly installed below the flat plate, a sizing roller is rotatably connected below the connecting plate, and support columns are fixedly installed on both sides of the bottom of the flat plate.

[0020] As a further solution of the present invention: wherein, right-angled sides a are provided on both sides of the bottom of the connecting plate, which are in contact with the discharge hole, and the two sides of the connecting plate are designed in an S-shape to form a triangular pre-storage space b between the discharge hole; when the discharge hole is closed, the right-angled side a is in contact with the bottom side of the discharge hole, and the bottom of the right-angled side a is designed with an arc-shaped side c.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The sizing device in this embodiment provides steam through a steam output device, which enters the interior of the drive drum through a connecting pipe and then is discharged through the air vents to contact the surface of the textile fabric.

[0023] 2. The sizing device in this embodiment pours slurry into the material storage bin, and the slurry flows along the conical material storage bin to the bottom and gathers at the bottom. The weight of the gathered slurry gradually increases, and then the force acting on the blocking plate will become larger, and the blocking plate will be pressed to move downward to open the discharge hole. At the same time, due to the increase in the overall weight of the material storage bin, the whole will also move downward on the guide rod to approach the transmission roller and the textile fabric wrapped on the transmission roller; thereby achieving the effect of uniform sizing if there is too little slurry in the initial or final stage.

[0024] 3. The sizing process in this embodiment achieves uniform sizing by passing the textile fabric over a steam-discharging transmission drum and then sizing the fabric with a feed mechanism located above the transmission drum. This eliminates the problem of uneven sizing caused by insufficient sizing at the initial and final stages, thereby saving sizing material and improving the efficiency of textile sizing.

[0037] See also Figure 1, which is a schematic diagram of the overall structure of this embodiment, the sizing device includes a support frame 10, internally connected to a set of relatively rotating drive rollers 20. The support frame 10 is provided with adjustment mechanisms 30 on both sides of the drive rollers 20 in the discharge and feed directions, and a feed mechanism 40 for conveying slurry is also provided above the support frame 10. In this embodiment, the sizing process is completed on the textile fabric by passing the textile fabric through the adjustment mechanism 30 and the drive rollers 20 and under the action of the feed mechanism 40.

[0038] like Figure 2 As shown, the right side of the transmission roller 20 is the feed port, and the left side is the discharge port. The textile fabric enters the interior of the support frame 10 through the feed port and contacts the transmission roller 20 below. After contact, it turns upward and contacts the transmission roller 20 above, and then is discharged through the discharge port on the left. On this basis, the rotation directions of the upper and lower transmission rollers 20 are arranged relative to each other, with the lower transmission roller 20 rotating clockwise and the upper transmission roller 20 rotating counterclockwise. As the transmission rollers 20 rotate, the textile fabric can also be transported from right to left through the sizing device.

[0039] Furthermore, the interior of the drive drum 20 is hollow and has a number of evenly spaced air holes (not shown) on its surface. A connecting pipe 21 is provided on one side of the drive drum 20, and an external steam output device is provided on the connecting pipe 21. In this embodiment, steam is provided by the steam output device through the connecting pipe 21 into the interior of the drive drum 20, and then discharged through the air holes and contacts the surface of the textile fabric, providing hot steam treatment before and after sizing, which is beneficial to increase the temperature and wettability of the fabric surface and facilitate the subsequent full and even diffusion of the slurry on the fabric. In this embodiment, the two drive drums 20 are arranged in an upper and lower structure and rotate in opposite directions. This design can not only transport the textile fabric, but also provide the textile fabric with a maximum area wetting effect, so that it can maintain a better wetting effect before sizing.

[0040] like Figure 3 and Figure 4As shown, further, the adjustment mechanism 30 includes a fixed frame 31 fixedly mounted on the side of the support frame 10, and a group of mutually symmetrical fixed frames 31 are provided on one side of the support frame 10, a sliding groove 32 is provided inside the fixed frame 31, and two symmetrically distributed sliding blocks 33 are slidably connected inside the sliding groove 32, and a connecting spring 34 is provided between the two sliding blocks 33, and a guide roller 35 is rotatably connected between the sliding blocks 33 located inside two different fixed frames 31, and the two guide rollers 35 are combined to form a material port, the left side of the support frame 10 is the material outlet, and the right side of the support frame 10 is the material feed port. In order to better fit the fabric, an adjustment screw extending into the interior of the fixed frame 31 and connected to the sliding block 33 is provided on the upper and lower end surfaces of the fixed frame 31. By adjusting the adjustment screw, the distance between the two guide rollers 35 can be adjusted, thereby achieving a better fit for textile fabrics of different thicknesses.

[0041] The feeding mechanism 40 includes a guide rod 41 fixedly connected to the top of the support frame 10. A fixing plate 42 is slidably connected to the guide rod 41. The lower end of the fixing plate 42 is provided with a return spring 43 that is sleeved on the guide rod 41. A material storage bin 44 is fixedly installed between the two fixing plates 42. The bottom of the material storage bin 44 is provided with a discharge hole 45. In this embodiment, the slurry can be poured into the material storage bin 44 and then discharged from the discharge hole 45 in the material storage bin 44 to contact the textile fabric, thereby achieving the sizing operation of the textile fabric.

[0042] like Figure 5 As shown, the shape of the storage bin 44 is a conical design. The design of the conical storage bin 44 allows the slurry to enter the interior of the storage bin 44 more smoothly, and the slurry above the storage bin 44 can be discharged more quickly from the discharge hole 45. After the slurry is poured in, due to the weight of the slurry, the slurry inside the storage bin 44 increases, which drives the fixed plate 42 to slide downward on the guide rod 41, thereby squeezing the return spring 43. The return spring 43 has elastic potential energy. At this time, due to the downward movement of the storage bin 44, the distance between the lower end of the storage bin 44 and the transmission roller 20 is reduced, so that the distance between the lower end of the storage bin 44 and the textile fabric will become smaller. When the slurry in the storage bin 44 decreases, the storage bin 44 will move upward under the action of the elastic potential energy of the return spring 43, away from the transmission roller 20 and the textile fabric.

[0043] like Figure 6 、 Figure 7 and Figure 8As shown, in order to further achieve uniform sizing of textile fabrics, a blanking component 46 is provided on the discharge hole 45, and the blanking component 46 includes a blocking plate 461 embedded in the discharge hole 45, and a guide rod 462 fixedly installed on the bottom of the material storage bin 44, and a slidable sliding sleeve 463 is sleeved on the guide rod 462, and the sliding sleeve 463 is fixedly connected to the top of the blocking plate 461 through a connecting rod 464, and a fixed spring 465 with one end fixedly connected to the sliding sleeve 463 is sleeved on the guide rod 462. In this embodiment, by pouring slurry into the storage bin 44, the slurry flows along the conical storage bin 44 to the bottom and gathers at the bottom. The weight of the accumulated slurry gradually increases, and the force acting on the blocking plate 461 becomes larger, which will press the blocking plate 461 to move downward to open the discharge hole 45. At the same time, due to the increase in the overall weight of the storage bin 44, the entire storage bin 44 will also move downward on the guide rod 41 to approach the transmission roller 20 and the textile fabric wrapped around the transmission roller 20; thereby achieving the effect of uniform sizing even if there is too little slurry at the initial or final stage. Direct discharge will result in the slurry not being evenly sizing the textile fabric. For example, at the initial stage, because the slurry has just been poured and the amount of slurry is too small, if it is directly discharged and contacts the fabric, the textile fabric will be unevenly sizing at the beginning, and at the final stage, because there is not much slurry left, the textile fabric at the tail end will also be unevenly sizing. However, in the device of the present application, only after a sufficient amount of slurry is poured into the interior of the silo 44 , the discharge hole 45 of the silo 44 will be opened, and the slurry will be applied to the textile fabric.

[0044] like Figure 9 and Figure 10 As shown above, the spring constant of the return spring 43 is smaller than the spring constant of the fixed spring 465. When slurry is poured into the hopper 44, the return spring 43 deforms first, causing the hopper 44 to move downward. When the weight of the slurry inside the hopper 44 reaches a certain level, the fixed spring 465 is further deformed, thereby opening the discharge hole 45. That is, after slurrying is completed, a certain amount of slurry will still remain inside the hopper 44. At this time, because the hopper 44 moves upward, the distance between the discharge hole 45 and the transmission drum 20 increases, making it easier to manually open the discharge hole 45 to discharge the remaining slurry and avoid wasting raw materials.

[0045] Specifically, the blocking plate 461 includes a flat plate 4611 parallel to the bottom of the material storage bin 44, and a connecting plate 4612 embedded in the discharge hole 45 is fixedly installed below the flat plate 4611. The bottom of the connecting plate 4612 is provided with right-angled sides a that fit with the discharge hole 45 on both sides, and the two sides of the connecting plate 4612 are designed in an eight-shaped shape to form a triangular pre-storage space b between the connecting plate 4612 and the discharge hole 45; when the discharge hole 45 is closed, the right-angled side a fits with the bottom side of the discharge hole 45. A sizing roller 4613 is rotatably connected to the bottom of the connecting plate 4612. In this embodiment, when the slurry is poured into the material storage bin 44, the slurry will first fill the gap downwards. After the bottom gap is filled, the slurry will continue to enter and exert pressure on the flat plate 4611. The portion of the connecting plate 4612 that contacts the discharge hole 45 is shaped like a figure eight, allowing the slurry to enter the triangular pre-storage space b. Once the right-angled side a is opened, the slurry pre-stored in the triangular pre-storage space b immediately enters the discharge hole 45 to sizing the textile fabric. This ensures uniform sizing even in the initial stage.

[0046] Furthermore, support columns 4614 are fixedly installed on both sides of the bottom of the flat plate 4611. As the weight of the slurry increases, the flat plate 4611 will be pressed downward and moved. After moving to a certain distance, the support columns 4614 will contact the bottom of the material storage bin 44, thereby preventing the flat plate 4611 from continuing to move downward.

[0047] Furthermore, the curved side c is designed below the right-angled side a. When the right-angled side a leaves the discharge hole 45, the slurry flows along the curved side c onto the surface of the sizing roller 4613 arranged below. As the textile fabric is transported, the sizing roller 4613 in contact with it rotates, thereby evenly sizing the slurry flowing from the sizing roller 4613 onto the textile fabric. During this process, the sizing roller 4613 receives the slurry from both sides, which plays a role in rapid sizing.

[0048] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
