Description

Technical Field

[0001] This utility model relates to the technical field of yarn processing equipment, specifically to a yarn sizing device. Background Technology

[0002] Yarn sizing is an important process for enhancing yarn strength and improving weaving performance. It involves applying sizing agent to the yarn surface to form a protective layer, reducing friction, increasing abrasion resistance, and improving weaving efficiency. Its core functions are: 1. Enhancing abrasion resistance: The sizing agent adheres to the yarn surface to form a protective layer, reducing wear on warp yarns during weaving and lowering the breakage rate; 2. Improving weavability: It improves the elasticity and conformability of warp yarns, avoiding problems such as yarn skipping and pattern skipping caused by tangling, making it easier for warp yarns to pass through the heddle and reed teeth of the loom; 3. Maintaining stable tension: By enhancing the breaking strength and elongation at break of the yarn, it ensures that the warp yarns can withstand repeated stretching and compression during weaving without easily breaking. Therefore, yarn sizing is a very important process.

[0003] Existing yarn sizing is generally carried out by sizing devices, such as the sizing device for preventing yarn overlap disclosed in CN210558607U, which sizing is carried out by passing the yarn into the sizing material in the sizing tank. However, the length of the yarn immersed in the sizing material cannot be adjusted by this device, and the excess sizing material on the yarn cannot be removed after the yarn comes out of the sizing material, which affects the subsequent drying efficiency. Utility Model Content

[0004] The present invention provides a yarn sizing device to solve the above-mentioned technical problems. The device can adjust the length of the yarn immersed in the sizing material, and can squeeze out the excess sizing material from the yarn through a squeezing device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model for a yarn sizing device is as follows:

[0006] The device includes a sizing tank, on which two transmission mechanisms are slidably connected laterally. Each transmission mechanism includes a movable panel, a lower transmission frame, and an upper extrusion frame. Multiple sets of longitudinally arranged transmission rollers are connected to the lower transmission frame. A pressure rod is connected to the upper extrusion frame. An extrusion device for pressing yarn into sizing is installed on the pressure rod. The movable panel is slidably connected above the sizing tank and is also connected to a limiting device for self-limitation. A filter box is placed in the center of the movable panel. The extrusion device is located directly above the filter box. A guide roller is also connected to the side of the sizing tank.

[0007] The extrusion device includes a rotating connecting rod; both ends of the rotating connecting rod are connected to a first vertical screw; both first vertical screws are vertically slidably connected to the pressure rod, and the upper ends of the first vertical screws are threaded through the pressure rod and connected to a limit block; a spring is placed between the limit block and the pressure rod; an extrusion roller corresponding to the conduction roller group is rotatably connected to the rotating connecting rod, and each conduction roller group is provided with a corresponding extrusion roller.

[0008] The pressure rod is connected to a set of limiting rings corresponding to the extrusion rollers; the set of limiting rings includes two limiting rings located on both sides of the extrusion rollers respectively.

[0009] The slurry tank is connected to two transverse sliding rods on both the front and rear sides; the movable panel is placed on the two transverse sliding rods and can slide laterally along the two transverse sliding rods; the limiting device includes two limiting plates corresponding to the two transverse sliding rods respectively; four second vertical screws are connected to the limiting plates; the upper ends of the four second vertical screws are threaded through the movable panel and connected to locking nuts; the transverse sliding rods are located between the movable panel and the limiting plates.

[0010] The lower transmission frame is connected to two fixed rods arranged vertically below it; the transmission roller group includes an upper guide roller and a lower guide roller; the upper guide roller and the lower guide roller are respectively rotatably connected to the two fixed rods.

[0011] The upper ends of both sides of the lower transmission frame are connected to third threaded connecting rods; the upper ends of both third threaded connecting rods pass through the movable panel and are threadedly connected to limit caps.

[0012] The lower transmission frame is connected to nine sets of longitudinally equidistant transmission rollers, and nine extrusion rollers are rotatably connected to the corresponding rotating connecting rods. Nine sets of limiting rings are connected to the corresponding pressure rods.

[0013] The technical effects that this utility model can achieve are:

[0014] 1. This utility model has two transmission mechanisms that are laterally slidably connected on the sizing tank. The yarn is transmitted through the transmission roller group below the two transmission mechanisms and thus immersed in the sizing. Therefore, by adjusting the distance between the two transmission mechanisms, the length of the yarn immersed in the sizing can be adjusted, thereby adjusting the sizing effect of the yarn.

[0015] 2. In this invention, after the yarn comes out of the sizing agent, the pressure bar above the transmission mechanism and the extrusion device press the yarn to remove excess sizing agent and speed up the drying efficiency of the subsequent yarn; while the squeezed-out excess sizing agent falls into the filter box, and after being filtered by the filter box, it flows back into the sizing agent tank.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] See Figures 1 to 6 .

[0025] A yarn sizing device includes a sizing tank 1, with two transmission mechanisms slidably connected laterally to the sizing tank 1. Each transmission mechanism includes a movable panel 2, a lower transmission frame 3, and an upper extrusion frame 4. The lower transmission frame 3 is connected to multiple sets of longitudinally arranged transmission rollers; specifically, the lower transmission frame 3 has nine sets of longitudinally equidistantly arranged transmission rollers. The upper extrusion frame 4 is connected to a pressure rod 5, and the pressure rod 5 is equipped with an extrusion device for sizing the yarn. Specifically, the extrusion device includes a rotating connecting rod 11, with first vertical screws 12 connected to both ends of the rotating connecting rod 11. Both first vertical screws 12 are vertically slidably connected to the pressure rod 5. Furthermore, the upper ends of the first vertical screw 12 all pass through the pressure rod 5 and are threadedly connected to the limiting block 13. A spring 14 is placed between the limiting block 13 and the pressure rod 5. The rotating connecting rod 11 is rotatably connected to the extrusion roller 15 corresponding to the transmission roller group, and each transmission roller group is provided with a corresponding extrusion roller 15. Preferably, the pressure rod 5 is connected to the limiting ring group corresponding to the extrusion roller 15. The limiting ring group includes two limiting rings 16 located on both sides of the extrusion roller 15. More specifically, the rotating connecting rod 11 is rotatably connected to nine extrusion rollers 15, and the corresponding pressure rod 5 is connected to nine sets of limiting ring groups.

[0026] When the yarn passes through the extrusion device, it enters between the extrusion roller 15 and the pressure rod 5. The extrusion roller 15 and the pressure rod 5 squeeze out excess sizing material from the yarn, thereby accelerating the drying efficiency of the yarn in the subsequent drying process. Furthermore, the pressure of the extrusion roller 15 on the yarn can be adjusted by rotating the limiting block 13. When the distance between the limiting block 13 and the rotating connecting rod 11 is smaller, the spring 14 is compressed shorter, and the pressure of the extrusion roller 15 on the yarn is greater. Conversely, when the distance between the limiting block 13 and the rotating connecting rod 11 is larger, the pressure of the extrusion roller 15 on the yarn is smaller.

[0027] Preferably, a filter box 6 is placed in the middle of the movable panel 2 of this utility model, and the extrusion device is located directly above the filter box 6. After the excess sizing material in the yarn is squeezed out, the excess sizing material falls onto the filter box 6 and flows back into the sizing tank 1 for reuse after being filtered by the filter box 6.

[0028] The movable panel 2 is slidably connected to the top of the slurry tank 1, and a limiting device for limiting its own position is also connected to the movable panel 2. Specifically, the front and rear sides of the slurry tank 1 are connected to horizontal slide rods 21. The movable panel 2 is placed on the two horizontal slide rods 21 and can slide laterally along the two horizontal slide rods 21. The limiting device includes two limiting plates 22 that correspond to the two horizontal slide rods 21 respectively. Four second vertical screws 23 are connected to the limiting plates 22. The upper ends of the four second vertical screws 23 all pass through the movable panel 2 and are threaded with locking nuts 24. The horizontal slide rods 21 are located between the movable panel 2 and the limiting plates 22.

[0029] The transmission mechanism of this utility model is laterally slidably connected to two transverse slide rods 21 via a movable panel 2. Therefore, the distance between the two transmission mechanisms can be adjusted as needed. When the required distance is reached, the movable panel 2 is limited by tightening the locking nut 24 and utilizing the friction between the transverse slide rods 21, the movable panel 2, and the limiting plate 22. This utility model adjusts the length of the yarn immersed in the sizing by adjusting the distance between the two transmission mechanisms, thereby adjusting the sizing effect of the yarn.

[0030] More specifically, the lower transmission frame 3 is connected to two fixed rods 31 arranged vertically below it. The transmission roller group includes an upper guide roller 32 and a lower guide roller 33, which are rotatably connected to the two fixed rods 31 respectively. The upper ends of both sides of the lower transmission frame 3 are connected to third threaded connecting rods 41. The upper ends of the two third threaded connecting rods 41 pass through the movable panel 2 and are threaded to limit caps 42. The side of the slurry tank 1 is also connected to a guide roller 7. The lower transmission frame 3 of this utility model is detachably connected to the movable panel 2. When it needs to be disassembled, the lower transmission frame 3 can be removed by unscrewing the limit caps 42. Its disassembly is relatively convenient.

[0031] Instructions for use: The yarn of this invention is first introduced into the sizing tank 1 through the guide roller assembly of the two guide mechanisms. Specifically, the yarn passes between the upper guide roller 32 and the lower guide roller 33 (see reference). Figure 1 , 2 After the slurry is applied, it passes around the guide roller 7 and is guided to the extrusion device of the two transmission mechanisms. The extrusion device of the two transmission mechanisms extrudes the slurry to remove excess slurry. The excess slurry falls onto the filter box 6 and flows back into the slurry tank 1 for reuse after being filtered by the filter box 6.
