Description

Technical Field

[0001] This application relates to the technical field of dyeing machinery, and in particular to a yarn dyeing machine. Background Technology

[0002] A yarn dyeing machine is a device used to dye yarn. Its core function is to dye different fiber materials through specific processes and equipment.

[0003] In related technologies, one can refer to the Chinese utility model patent with authorization announcement number CN221956327U, which discloses a high-quality anti-pilling yarn dyeing machine, including a dyeing box, four support columns arranged in a matrix array fixedly connected to the lower end of the dyeing box, a first mounting plate fixedly connected to one side of the upper end of the dyeing box, a lead screw rotatably connected to the lower end of the first mounting plate, a placement plate being threaded onto the outside of the lead screw, and a motor fixedly connected to the upper end of the first mounting plate.

[0004] However, in actual use, the dyeing machine described above has a problem: the lead screw is installed inside the dyeing box and exposed. When the yarn is dyed by the dye liquor in the dyeing box, the dye liquor will carry some dust, fiber debris and other objects out of the yarn. These objects mix with the grease and residual pigments in the dye liquor to form impurities. These impurities can easily adhere to the lead screw, which will have an adverse effect on the transmission effect of the lead screw. This makes it very inconvenient for the staff to clean the lead screw frequently, and the structural design is not reasonable. Utility Model Content

[0005] In order to reduce the contamination of transmission components by impurities in the dye bath, improve the stability of equipment operation, and reduce the cleaning frequency, this application provides a yarn dyeing machine.

[0006] This application provides a yarn dyeing machine, which adopts the following technical solution:

[0007] A yarn dyeing machine includes a frame and a dyeing barrel mounted on the frame. Yarn is placed in the dyeing barrel for dyeing. A dye liquor tank, filled with dye liquor, is mounted on the frame to one side of the dyeing barrel. A liquor adding device is mounted on the frame to add dye liquor from the dye liquor tank into the dyeing barrel. A placement platform is provided inside the dyeing barrel, with its top height higher than the dye liquor level in the dyeing barrel. A mounting frame is placed on the placement platform, and a connecting component is provided on the mounting frame. A yarn frame is detachably connected to the mounting frame via the connecting component. Yarn is wound around the yarn frame, which is immersed in the dye liquor in the dyeing barrel. A lifting mechanism is provided on the placement platform to control the lifting and lowering of the mounting frame placed on the placement platform.

[0008] By adopting the above technical solution, a placement platform is installed inside the dyeing tank, with the height of the platform set above the dye liquor level. The mounting frame is placed on the platform and then raised and lowered by a lifting mechanism. This avoids direct immersion of the mounting frame and lifting mechanism by the dye liquor, reduces the probability of impurities adhering to the lifting mechanism and causing contamination to the transmission components, and ensures stable equipment operation. Furthermore, by detachably connecting the yarn rack and the mounting frame, it is convenient to replace the yarn rolls without having to move the entire mounting frame out of the dyeing tank, greatly improving work convenience and efficiency.

[0009] Optionally, the connection component includes:

[0010] A connecting rod, one end of which is mounted on the mounting frame, and the other end of which extends vertically downward to below the surface of the dye solution in the dyeing tank;

[0011] A connecting ring is disposed at the bottom end of the connecting rod;

[0012] A plurality of connecting hooks are provided, and the plurality of connecting hooks are evenly distributed on the connecting ring, and the yarn frame is hung on the connecting hooks.

[0013] By adopting the above technical solution, the connection hooks and the yarn rack are coordinated to make the installation and disassembly of the yarn rack more convenient. Moreover, the multiple hooks are evenly distributed to ensure that the yarn rack is subjected to balanced force and is not easy to shake during the dyeing process.

[0014] Optionally, the lifting mechanism is provided in two sets, with the two sets of lifting mechanisms located on both sides of the mounting frame in the horizontal direction, and the lifting mechanism includes:

[0015] The lifting block has a vertical sliding groove on the surface of the placement platform. The lifting block is slidably installed on the sliding groove, and the top of the lifting block abuts against the bottom of the mounting frame.

[0016] A lifting rack, wherein the lifting rack is mounted on the lifting block;

[0017] A lifting gear is rotatably mounted on a placement platform and located in a sliding groove, and the lifting gear meshes with a lifting rack;

[0018] A lifting motor is installed outside the dyeing barrel, and its output shaft extends into the sliding groove and is connected to the lifting gear.

[0019] By adopting the above technical solution, the lifting motor starts and drives the lifting gear to rotate. The rotation of the lifting gear drives the lifting rack to move, the movement of the lifting rack drives the lifting block to move, and the movement of the lifting block drives the mounting frame to move. Thus, the lifting and lowering of the mounting frame is achieved by controlling the lifting motor. The two sets of lifting mechanisms operate synchronously, making the lifting and lowering of the mounting frame more stable. The lifting motor is located outside the dyeing vat to avoid contact with the dye liquor and reduce the impact of impurities on the motor. The gear and rack transmission has high precision and can accurately control the lifting height of the yarn rack.

[0020] Optionally, the top of the lifting block is provided with a snap-fit ​​groove, and the mounting bracket engages with the snap-fit ​​groove.

[0021] By adopting the above technical solution, the snap-fit ​​connection enhances the connection stability between the mounting frame and the lifting block, preventing the mounting frame from shifting or falling off during the lifting process and improving the safety of equipment operation.

[0022] Optionally, a soft sealing pad is provided on the side of the lifting block, and a magnetic buckle is provided at the bottom of the soft sealing pad. A magnet is provided on the surface of the placement platform located on the side of the lifting block, and the magnet and the magnetic buckle attract each other.

[0023] By adopting the above technical solutions, the soft sealing gasket can reduce the seepage of dye into the sliding groove and prevent the lifting gear and lifting rack from being contaminated by impurities; the magnetic buckle and the magnetic block's adsorption effect further enhance the sealing effect, while improving the tightness of the connection between the lifting block and the placement platform.

[0024] Optionally, a lid is rotatably mounted on the dyeing barrel, which covers the upper opening of the dyeing barrel. A control component is provided on the dyeing barrel to drive the lid to rotate.

[0025] By adopting the above technical solution, the control component realizes the automatic opening and closing of the barrel lid without manual operation, saving manpower; the barrel lid can reduce the evaporation of dye liquor, while preventing external impurities from entering the dyeing barrel and ensuring the purity of the dye liquor.

[0026] Optionally, the control component includes:

[0027] A rotating shaft is rotatably mounted on the outer wall of the dyeing tank;

[0028] The control panel is mounted on the rotating shaft and one end is connected to the bucket lid.

[0029] A control cylinder is rotatably mounted on the outer wall of the dyeing barrel;

[0030] A control lever, which is rotatably mounted on a control panel and connected to the piston rod of a control cylinder.

[0031] By adopting the above technical solution, the control cylinder is started to drive the control rod to move, the control rod to move, the control rod to move, the control plate to rotate around the shaft, and the rotation of the control plate to move the lid. Thus, the opening and closing of the lid is achieved by controlling the control cylinder.

[0032] Optionally, the bucket lid is provided with an elastic sealing ring, which abuts against the surface of the placement platform.

[0033] By adopting the above technical solution, the elastic sealing ring enhances the sealing performance between the barrel lid and the dyeing barrel, further reducing dye liquor evaporation and external pollution. On the other hand, it also protects the mounting frame and the opening of the sliding trough, reducing the probability of dye liquor entering the sliding trough. At the same time, the elastic sealing ring can also play a buffering role when the barrel lid is closed, reducing noise and component wear.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By installing a placement platform inside the dyeing tank and setting the height of the placement platform to be higher than the surface of the dye liquor, the mounting frame is placed on the placement platform and then raised and lowered by the lifting mechanism. This avoids the dye liquor directly immersing the mounting frame and lifting mechanism, reduces the probability of impurities adhering to the lifting mechanism and thus contaminating the transmission components, and ensures the stable operation of the equipment.

[0036] 2. By detachably connecting the yarn rack and the mounting frame, it is easy to replace the yarn rolls without having to move the entire mounting frame out of the dyeing tank, which greatly improves the convenience and efficiency of the work.

[0037] 3. By controlling the cylinder to start, the control lever moves, which in turn moves the control plate around the pivot. The rotation of the control plate moves the lid, thus controlling the cylinder to open and close the lid. Attached Figure Description

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0044] This application discloses a yarn dyeing machine.

[0045] Reference Figure 1 and Figure 2 The yarn dyeing machine includes a frame 1, on which a dyeing tank 11 and a dye liquor tank 12 are fixed. The dye liquor tank 12 supplies dye liquor to the dyeing tank 11 through a liquor adding device 13 (such as a pump and pipes). A placement platform 14 is fixedly installed on the inner wall of the dyeing tank 11, and the upper surface of the placement platform 14 is higher than the dye liquor level. A mounting frame 15 is placed on the upper surface of the placement platform 14. A connecting component 2 is provided on the mounting frame 15, and a yarn frame 16 is detachably connected to the mounting frame 15 through the connecting component 2. The yarn is wound on the yarn frame 16, and the yarn frame 16 is completely immersed in the dye liquor. Two sets of lifting mechanisms 3 are provided on the placement platform 14 for driving the mounting frame 15 to rise and fall.

[0046] Reference Figure 2 The connecting assembly 2 includes a connecting rod 21, a connecting ring 22, and connecting hooks 23. One end of the connecting rod 21 is fixed to the bottom of the mounting frame 15, and the other end extends vertically downward to below the surface of the dye liquor. The connecting ring 22 is fixedly installed at the bottom end of the connecting rod 21. Several connecting hooks 23 are provided, and the several connecting hooks 23 are evenly distributed on the outer wall of the connecting ring 22. The yarn frame 16 is hung on the connecting hooks 23.

[0047] Reference Figure 2 and Figure 3Two sets of lifting mechanisms 3 are located on opposite sides of the mounting frame 15 in the horizontal direction. Each set of lifting mechanisms 3 includes a lifting block 31, a lifting rack 32, a lifting gear 33, and a lifting motor 34. A vertical sliding groove 17 is provided on the surface of the placement platform 14, and the lifting block 31 is slidably installed in the sliding groove 17. A snap-fit ​​groove 35 is provided on the top of the lifting block 31, and the mounting frame 15 is snap-fitted into the snap-fit ​​groove 35 located on the top of the lifting block 31. The lifting rack 32 is fixedly installed on the outer wall of the lifting block 31. The lifting gear 33 is rotatably installed in the sliding groove 17 and meshes with the lifting rack 32. The lifting motor 34 is fixedly installed on the outer wall of the dyeing barrel 11, and its output shaft extends into the sliding groove 17 and is connected to the lifting gear 33.

[0048] Reference Figure 2 The lifting motor 34 starts, driving the lifting gear 33 to rotate. The rotation of the lifting gear 33 drives the lifting rack 32 to move, which in turn drives the lifting block 31 to move. The movement of the lifting block 31 then drives the mounting frame 15 to move, thus achieving the lifting and lowering of the mounting frame 15 by controlling the lifting motor 34. The two lifting mechanisms 3 operate synchronously, making the lifting and lowering of the mounting frame 15 more stable. The lifting motor 34 is located outside the dyeing tank 11 to avoid contact with the dye liquor, reducing the impact of impurities on the lifting motor 34. The gear and rack transmission has high precision, allowing for accurate control of the lifting height of the yarn frame 16.

[0049] Reference Figure 2 and Figure 3 A soft sealing pad 36 is fixedly installed on the top of the lifting block 31 near the side wall of the lifting block 31. A magnetic buckle 37 is installed at the bottom of the soft sealing pad 36. A magnet 38 is provided at the corresponding position of the placement platform 14. The magnetic buckle 37 and the magnet 38 are attracted to each other, thereby enhancing the sealing of the sliding groove 17 and preventing the dye liquid from seeping in.

[0050] Reference Figure 1 and Figure 2 A control component 4 is provided on the dyeing barrel 11, and a barrel lid 18 is rotatably mounted on the dyeing barrel 11 via the control component 4. An elastic sealing ring is fixedly installed at the bottom of the barrel lid 18. When the barrel lid 18 closes the upper opening of the dyeing barrel 11, the elastic sealing ring abuts against the surface of the placement platform 14.

[0051] Reference Figure 1 and Figure 4The control assembly 4 includes a rotating shaft 41, a control plate 42, a control cylinder 43, and a control rod 44. The rotating shaft 41 is rotatably mounted on the outer wall of the dyeing barrel 11. The control plate 42 is fixedly mounted on the rotating shaft 41, with one end connected to the surface of the barrel lid 18. The control cylinder 43 is rotatably mounted on the outer wall of the dyeing barrel 11. The control rod 44 is rotatably mounted on the control plate 42 and connected to the piston rod of the control cylinder 43. When the control cylinder 43 is activated, it drives the control rod 44 to move. The movement of the control rod 44, in turn, drives the control plate 42 to rotate around the rotating shaft 41. The rotation of the control plate 42 drives the barrel lid 18 to move, thus realizing the opening and closing of the barrel lid 18 by controlling the control cylinder 43.

[0052] The working principle of this application embodiment is as follows:

[0053] During dyeing, the yarn is wound onto the yarn holder 16, and the yarn holder 16 is hung on the connecting ring 22 via the connecting hook 23. The lifting motor 34 is started, and the lifting gear 33 drives the lifting rack 32 to move downwards. The lifting block 31 descends accordingly, and the mounting frame 15 and yarn holder 16 move downwards synchronously until the yarn holder 16 is completely submerged in the dye solution. The bucket lid 18 is closed. After dyeing is complete, the lifting mechanism 3 lifts the mounting frame 15, detaching the yarn holder 16 from the dye solution. The bucket lid 18 can then be opened to remove the yarn holder 16. This completes the yarn dyeing process. Furthermore, it avoids direct immersion of the mounting frame 15 and lifting mechanism 3 by the dye solution, reducing the probability of impurities adhering to the lifting mechanism 3 and contaminating the transmission components, thus ensuring stable equipment operation.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
