Description

Technical Field

[0001] The present application relates to the field of devices for producing yarn-dyed fabrics, and in particular to a sizing machine for producing yarn-dyed fabrics. Background Art

[0002] A sizing machine is a device used for sizing cotton or cotton-type chemical fiber blended yarn. The existing Chinese utility model patent with authorization announcement number CN203451837U discloses a sizing machine, including a frame, a sizing tank and an oven. The frame is fixed with a sizing tank, a sizing roller is provided on the sizing tank, and front pressure rollers and rear pressure rollers are provided on both sides of the sizing roller. An oven is also provided on the frame, and a temperature detector is provided in the oven. The temperature detector controls a fan provided below the oven. A motor frame is provided below the frame, and two motors are provided on the motor frame.

[0003] In the process of sizing the yarn-dyed fabric, the slurry in the slurry tank needs to be heated to keep the slurry at a suitable temperature. As the slurry in the slurry tank gradually decreases, the slurry attached to the inner wall of the slurry tank is easily dried on the inner wall of the slurry tank due to the influence of heating. The dried slurry is easy to drop residue into the slurry, and then the slurry roller may cover the residue on the yarn-dyed fabric, which has an adverse effect on the quality of the finished product of the yarn-dyed fabric. Summary of the invention

[0004] In order to reduce the adverse effects on the quality of finished yarn-dyed fabric products, the present application provides a sizing machine for yarn-dyed fabric production.

[0005] The present application provides a sizing machine for color-dyed fabric production using the following technical solution:

[0006] A sizing machine for producing yarn-dyed fabrics, comprising a sizing tank, a sizing roller is installed in the sizing tank, the lowest point of the sizing roller is submerged in the sizing material, a ring-shaped scraper is slidably connected in the sizing tank, each inner side wall of the sizing tank is in contact with the scraper, and a driving component for driving the scraper to move in a height direction is installed in the sizing tank;

[0007] Both sides of the pulp roller are provided with filter boxes fixed with scrapers, and no filter holes are provided on the two short side walls of the filter box. The scrapers and the filter box are both higher than the slurry liquid level. The pulp tank is provided with a sealing box corresponding to the filter box one by one and located below the filter box, and both ends of the sealing box are open. A supporting spring corresponding to the sealing box is connected to the pulp tank, and the upper end of the supporting spring is connected to the sealing box.

[0008] A sealing plate is slidably connected to one side of each of the two long sides of the filter box, and a sealing plate in contact with the upper surface of the sealing box is connected to the top of the sealing plate. A transmission member is also provided under the sealing box, which converts the force of the filter box moving downward into a force that pulls the sealing plate to slide along the width direction of the sealing box.

[0009] By adopting the above technical scheme, when it is necessary to clean the solidified slurry on the side wall of the slurry tank, the operator starts the driving assembly, so that the scraper drives the filter box to move downward, and the filter box is moved into the sealing box. In the process of the filter box moving downward, the transmission member works to pull the two sealing plates towards each other until the sealing plates abut against the corresponding side walls of the filter box, and at the same time, the sealing plate seals the gap between the sealing box and the long side walls of the filter box; as the filter box continues to move, the filter box pushes the sealing box and the sealing plate to move downward, and the supporting spring is compressed while the sealing box moves. When the sealing plate is lower than the liquid level, the upper slurry flows into the filter box, and at the same time, the slurry brings the residue floating on the surface into the filter box.

[0010] The operator controls the driving assembly to move the scraper and the filter box upward, while the supporting spring recovers its deformation and pushes the sealing box and the sealing plate upward. When the sealing box returns to its initial position, as the filter box continues to move upward, the transmission member drives the two sealing plates to move away from the filter box. At this time, the slurry in the filter box flows out, and the residue in the slurry remains in the filter box, thereby reducing the occurrence of filter residue adhering to the yarn-dyed fabric and reducing the adverse effects on the quality of the finished yarn-dyed fabric. When the scraper and the filter box move to their initial positions, the sealing box, the sealing plate and the blocking plate all return to their initial positions.

[0011] Optionally, a pointed tip is provided at the lower end of the scraper.

[0012] By adopting the above technical solution, the scraper can better scrape off the slurry dried on the side wall of the slurry tank.

[0013] Optionally, a T-shaped slider is fixedly connected to the outer wall of the scraper, and a slide groove adapted to the slider is opened on the inner wall of the slurry groove. The length direction of the slide groove is arranged along the height direction of the slurry groove, and each slider is slidably inserted in the corresponding slide groove.

[0014] By adopting the above technical solution, the sliding block cooperates with the sliding groove to make the scraper and the pulp groove slide and cooperate.

[0015] Optionally, a plurality of I-shaped sliding blocks are connected to the lower surface of the sealing plate, and sliding holes corresponding to the sliding blocks are opened on the lower surface of the sealing box. The length direction of the sliding holes is arranged along the width direction of the sealing box, and each slider is slidably inserted in the corresponding sliding hole.

[0016] By adopting the above technical solution, the sliding block cooperates with the sliding hole to enable the sealing plate to slide and cooperate with the sealing box.

[0017] Optionally, the transmission member includes a transmission block disposed between the two sealing plates, and the transmission block corresponds one-to-one to a sliding block on one of the sealing plates;

[0018] The sliding block is connected to a limit spring, which is fixed to the hole wall corresponding to the sliding hole, and the limit spring makes the sliding block and the sealing plate located at the edge of the sealing box;

[0019] The sliding block is hinged with an articulated rod, which is hinged with the corresponding transmission block. The lower surface of the filter box is fixedly connected with a push rod corresponding to the transmission block. The lower surface of the sealing box is provided with a hole for the push rod to pass through.

[0020] By adopting the above technical solution, when the filter box moves into the sealing box, when the filter box drives the push rod to move and contact with the transmission block, the push rod moves and pushes the transmission block and the corresponding end of the hinged rod to move downward. At this time, the support spring supports the sealing box to make the transmission block move downward to the sealing box. The transmission block moves and drives the hinged rod to move, so that the two hinged rods rotate away from the end of the transmission block toward each other. When the hinged rod rotates, it pulls the corresponding sliding block, sealing plate and blocking plate to move.

[0021] When the filter box moves upward, the support spring recovers its deformation and pushes the sealing box, sealing plate, blocking plate, transmission block and hinged rod to move upward as a whole. When the support spring returns to its initial state, the sealing box moves to its initial position. At this time, as the filter box continues to move upward, the limit spring gradually recovers its deformation and pushes the sliding block, sealing plate and blocking plate to move, so that the sealing plate is reset, and at the same time drives the hinged rod and the transmission block to reset.

[0022] Optionally, the filter box is provided with a guide member for guiding the sealing box.

[0023] By adopting the above technical solution, the guide member guides the sealing box so that the sealing box can remain aligned with the filter box.

[0024] Optionally, the guide member includes a guide rod fixedly connected to the lower surface of the filter box, the guide rod passes through the lower surface of the sealing box and is slidably plugged with the sealing box.

[0025] By adopting the above technical solution, the filter box cooperates with the guide rod to guide the sealing box, so that the sealing box can remain aligned with the filter box.

[0026] Optionally, the number of the guide rods corresponds to the transmission block one by one, and the guide rods pass through the transmission block and are slidably plugged with the transmission block.

[0027] By adopting the above technical solution, the guide rod guides the transmission block, thereby reducing the occurrence of transmission block deviation.

[0028] Optionally, a plurality of limit blocks are fixedly connected to the inner side wall of the transmission block, and a limit groove corresponding to the limit blocks is opened on the side wall of the guide rod. The length direction of the limit groove is arranged along the height direction of the pulp groove, and each limit block is slidably inserted in the corresponding limit groove.

[0029] By adopting the above technical solution, the limiting block cooperates with the limiting groove to limit the transmission block, thereby reducing the rotation of the transmission block and thus reducing the torsion and bending of the hinged rod.

[0030] Optionally, the driving assembly includes a hydraulic cylinder installed on the pulp trough, and a telescopic rod of the hydraulic cylinder is fixedly connected to the scraper.

[0031] By adopting the above technical solution, when the scraper needs to be moved along the height direction of the pulp tank, the operator controls the extension and retraction of the telescopic rod of the hydraulic cylinder, and the extension and retraction of the telescopic rod of the hydraulic cylinder drives the scraper to move.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. By setting the pulp tank, pulp roller, scraper, drive assembly, sealing box, sealing plate and transmission parts, the adverse effects on the quality of the finished yarn-dyed fabric can be reduced;

[0035] 3. By setting the guide rod, the sealing box and the filter box can be aligned. BRIEF DESCRIPTION OF THE DRAWINGS

The slider 22 cooperates with the slide groove 12 to make the scraper 2 and the pulp groove 1 slide together.

[0045] A driving component for driving the scraper 2 to move along the height direction of the pulp tank 1 is provided in the pulp tank 1. In this embodiment, the driving component is two hydraulic cylinders 3, and the two hydraulic cylinders 3 are respectively distributed on both sides of the pulp tank 1. The hydraulic cylinders 3 are installed on the pulp tank 1, and the telescopic rods of the hydraulic cylinders 3 are connected and fixed to the scraper 2; in other embodiments, the driving component can also be a screw motor module, and the slide of the screw motor module is connected and fixed to the scraper 2.

[0046] Filter boxes 4 are provided at both sides of the pulp roller 11 in the pulp tank 1. The length direction of the filter boxes 4 is arranged along the axial direction of the pulp roller 11. Filter holes are provided on the filter boxes 4, and no filter holes are provided on the two short side walls of the filter boxes 4. Connecting rods 41 are fixedly connected to the outer walls of the two filter boxes 4 that are away from each other, and the connecting rods 41 are fixed to the inner walls corresponding to the scraper 2. In the initial state, the hydraulic cylinder 3 makes the scraper 2 and the filter box 4 higher than the slurry surface.

[0047] Reference Figure 2 and Figure 4 A sealing box 5 corresponding to the filter box 4 and located below the filter box 4 is further provided in the slurry tank 1. The length directions of the sealing box 5 and the filter box 4 are consistent. The length of the sealing box 5 is greater than the length of the filter box 4, and the width of the sealing box 5 is also greater than the length of the filter box 4. Both ends of the sealing box 5 are open. A supporting spring 51 is provided below the sealing box 5 to support the sealing box 5. The upper end of the supporting spring 51 is fixed to the lower surface of the sealing box 5, and the lower end of the supporting spring 51 is fixed to the inner bottom wall of the slurry tank 1.

[0048] Reference Figure 4 and Figure 5A guide member 7 for guiding the sealing box 5 is also provided in the slurry tank 1. The guide member 7 includes a plurality of guide rods 71 ​​fixedly connected to the lower surface of the filter box 4. Each guide rod 71 penetrates the lower surface of the sealing box 5 and is slidably plugged with the sealing box 5. The guide rods 71 ​​cooperate with the filter box 4 to guide the sealing box 5 so that the sealing box 5 remains aligned with the filter box 4.

[0049] Reference Figure 4 and Figure 5 Two sealing plates 6 are provided in the sealing box 5, and the sealing plates 6 are fixedly connected to the sealing plates 6. The length direction of the sealing plates 61 is consistent with the length direction of the sealing plates 6. The two sealing plates 6 are located between the two sealing plates 61, and the lower surface of the sealing plate 61 contacts the upper surface of the two long side walls of the sealing box 5.

[0050] A plurality of I-shaped sliding blocks 62 are fixedly connected to the lower surfaces of the two sealing plates 6. The number of sliding blocks 62 on the two sealing plates 6 is the same. When the number of sliding blocks 62 on the sealing plate 6 is one, the sliding block 62 is located in the middle of the sealing plate 6. When the number of sliding blocks 62 on the sealing plate 6 is greater than one, all sliding blocks 62 on the sealing plate 6 are distributed along the length direction of the sealing plate 6. Sliding holes 52 corresponding to the sliding blocks 62 are provided on the bottom surface of the sealing box 5. The length direction of the sliding holes 52 is arranged along the width direction of the sealing box 5. Each sliding block 62 is slidably inserted in the corresponding sliding hole 52. The sliding block 62 cooperates with the sliding hole 52 to enable the sealing plate 6 and the sealing box 5 to slide together.

[0051] A transmission member 8 is provided below the sealing box 5 to convert the force of moving the filter box 4 into driving the two sealing plates 6 to move. The transmission member 8 includes a transmission block 81 arranged below the sealing box 5. The number of the transmission blocks 81 corresponds to the number of sliding blocks 62 on one of the sealing plates 6, and each guide rod 71 passes through the corresponding transmission block 81 and is slidably inserted.

[0052] The transmission member 8 also includes a hinged rod 82 connected to the sliding block 62, and the hinged rod 82 is located below the sealing box 5. The end of the hinged rod 82 away from the sliding block 62 is hinged to the corresponding transmission block 81. The lower surface of the filter box 4 is fixedly connected with a plurality of push rods 84 corresponding to the transmission block 81, and the lower surface of the sealing box 5 is provided with holes for the push rods 84 to pass through; the sides of the two opposite sliding blocks 62 close to each other are fixedly connected with a limit spring 83, and the end of the limit spring 83 away from the sliding block 62 is fixed to the hole wall corresponding to the end of the sliding hole 52.

[0053] In the initial state, the support spring 51 supports the transmission block 81 and the sealing box 5, and the upper surfaces of the sealing plate 61 and the sealing box 5 are both higher than the liquid level of the slurry; the limit spring 83 limits the sliding block 62 and the corresponding sealing plate 6, so that the two sealing plates 6 are respectively distributed on the two side edges of the sealing box 5, and the distance between the side walls of the two sealing plates 6 close to each other is greater than the external width of the filter box 4. At this time, the limit spring 83, the sliding block 62 and the hinged rod 82 cooperate to make the transmission block 81 contact with the lower surface of the sealing box 5.

[0054] When it is necessary to clean the solidified slurry on the inner wall of the slurry tank 1, the operator controls the hydraulic cylinder 3, and the hydraulic cylinder 3 pushes the scraper 2 and the filter box 4 to move downward. When the scraper 2 moves, the solidified slurry on the inner wall of the slurry tank 1 is scraped off, and the scraped solidified slurry forms residue, which floats on the surface of the slurry; the scraper 2 moves and drives the two filter boxes 4 and the push rod 84 to move into the corresponding sealing box 5.

[0055] When the push rod 84 moves to contact the transmission block 81, as the filter box 4 and the push rod 84 continue to move downward, the push rod 84 pushes the transmission block 81 and the corresponding end of the hinged rod 82 to move downward, thereby rotating the hinged rod 82, and the two hinged rods 82 move away from the end of the transmission block 81 toward each other; at the same time, the hinged rod 82 pulls the corresponding sliding block 62, sealing plate 6 and blocking plate 61 to move until the two sealing plates 6 are in contact with the corresponding side walls of the filter box 4. At this time, the two sealing plates 6 block the sealing box 5, and the blocking plate 61 blocks the gap between the two long side walls of the filter box 4 and the sealing box 5.

[0056] Reference Figure 4 and Figure 5 In order to reduce the bending and twisting of the hinge rod 82 caused by the rotation of the transmission block 81, a plurality of limit blocks 72 are fixedly connected to the inner side wall of the transmission block 81, and a limit groove 711 corresponding to the limit block 72 is opened on the side wall of the guide rod 71. The length direction of the limit groove 711 is arranged along the height direction of the pulp tank 1. The limit block 72 is slidably inserted in the corresponding limit groove 711. The limit block 72 cooperates with the limit groove 711 to limit the transmission block 81, thereby reducing the rotation of the transmission block 81.

[0057] As the scraper 2 continues to drive the filter box 4 to move downward, the filter box 4 pushes the sealing box 5 to move downward, and the sealing box 5 compresses the support spring 51 when moving; when the sealing plate 61 and the upper surface of the filter box 4 are moved below the liquid surface, the slurry on the upper liquid surface flows into the filter box 4, thereby bringing the residue floating on the liquid surface into the filter box 4; then the operator controls the hydraulic cylinder 3 to work, so that the scraper 2 drives the filter box 4 to move upward.

[0058] When the filter box 4 moves, the support spring 51 recovers its deformation and drives the sealing box 5 to move upward. When the support spring 51 recovers to its initial state, as the filter box 4 continues to move upward, the limit spring 83 recovers its deformation and pushes the corresponding sliding block 62, sealing plate 6, blocking plate 61 and the corresponding end of the hinged rod 82 to move, so that the two hinged rods 82 move upward near one end of the transmission block 81, thereby moving the transmission block 81 upward; when the push rod 84 is out of contact with the transmission block 81, the sealing plate 6, blocking plate 61, transmission block 81 and hinged rod 82 all return to their initial positions.

[0059] During the resetting process of the blocking plate 61, after the blocking plate 61 is out of contact with the filter box 4, the slurry in the filter box 4 flows out along the filter holes, and at the same time the filter box 4 filters the slurry, and the residue is retained in the filter box 4 for collection, thereby reducing the situation where the slurry contains residue, thereby reducing the possibility of the residue adhering to the yarn-dyed fabric, and reducing the adverse effect on the quality of the finished yarn-dyed fabric; the slurry flowing out of the filter box 4 flows back to the slurry tank 1 through the openings at both ends of the sealing box 5.

[0060] The implementation principle of a sizing machine for color-dyed fabric production in the embodiment of the present application is as follows: when it is necessary to clean the solidified slurry on the slurry tank 1, the operator controls the hydraulic cylinder 3 to operate so that the scraper 2 and the filter box 4 move downward. After the filter box 4 moves into the sealing box 5, as the filter box 4 continues to move, the push rod 84 pushes the transmission block 81 to move, so that the hinge rod 82 pulls the two sealing plates 6 to move until the sealing plate 6 abuts against the filter box 4. At this time, the scraper 2 drives the filter box 4 and the sealing box 5 to move downward, and the slurry and residue on the upper layer flow into the filter box 4; then the operator controls the hydraulic cylinder 3 to operate so that the scraper 2, the filter box 4 and the sealing box 5 move upward. During this process, the sealing plate 6 moves away from the filter box 4, the slurry in the filter box 4 flows out, and the residue remains in the filter box 4. When the filter box 4 returns to its initial position, the sealing box 5, the sealing plate 6 and the transmission block 81 all return to their initial positions.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
