Description

Technical Field

[0001] This utility model relates to the field of yarn dyeing technology, and in particular to a spandex yarn dyeing mechanism. Background Technology

[0002] During the dyeing process of spandex yarn, it is usually carried out in a sealed container. Specifically, the yarn sleeves to be dyed are fitted one by one onto a base with several feeding rods. After the yarn sleeves are positioned by elastic positioning components, the hoist lifts the middle rod and finally places them directly into the dyeing cylinder filled with dye liquor for sealed heating treatment.

[0003] For example, Chinese patent application number CN202322989267.5 discloses a yarn dyeing device, including a cylindrical body with an inner cavity; a yarn base, which is vertically and flexibly disposed at the bottom of the inner cavity; a positioning sleeve vertically disposed at the upper center of the yarn base; and several feeding rods vertically disposed on the upper side of the yarn base around the outer periphery of the positioning sleeve. This device can solve the problem that fixing yarn in existing dyeing devices is often complex, time-consuming, and inefficient. However, it still involves individually attaching yarn sleeves to the fixed feeding rods, i.e., after obtaining the yarn sleeves, they are inserted one by one from the inside out onto the base via the upper end of the feeding rods. For larger bases, the outer feeding rods can affect the process of attaching the yarn sleeves to the feeding rods in the middle position, and the efficiency of placing the yarn sleeves needs to be improved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a spandex yarn dyeing mechanism to solve the technical problem that the existing technology still involves attaching yarn sleeves one by one to each fixed feeding rod. That is, after obtaining the yarn sleeves, they are inserted one by one from the inside to the outside onto the base through the upper end of the feeding rod. For bases with larger sizes, the outer feeding rods will affect the process of attaching the yarn sleeves to the feeding rods in the middle position, and the placement efficiency of the yarn sleeves needs to be improved.

[0005] To achieve the above objectives, this utility model provides a spandex yarn dyeing mechanism, including a yarn base disposed within a dyeing cylinder, a hanging post at the center of the yarn base, and a plurality of feeding rods on the yarn base, each feeding rod having a yarn sleeve fitted onto it. The hanging post is a split-type structure. The dyeing mechanism further includes:

[0006] Pressure plates are provided on both sides of the yarn sleeve, and the pressure plates are adjustablely mounted on the feed rod;

[0007] A socket is provided at the lower end of the feeding rod, and the side end of the socket is extended.

[0008] Several plugs are provided on the yarn base, and the socket is inserted into the plugs;

[0009] A pressure ring that mates with the extended side end of the socket;

[0010] A drive unit for driving the pressure ring to move up and down.

[0011] Furthermore, both the upper and lower parts of the hoisting pile are cylindrical structures, and the upper and lower parts of the hoisting pile are connected by bolts. A guide groove is provided in the lower part of the hoisting pile.

[0012] Furthermore, the drive unit includes:

[0013] A C-shaped connecting rod is slidably disposed in the guide groove, and the lower end of the connecting rod is fixedly connected to the pressure ring;

[0014] Rotate the threaded rod located inside the hoisting pile; the threaded rod is threadedly connected to the middle of the connecting rod.

[0015] A handwheel is located at the top of the threaded rod.

[0016] Furthermore, the handwheel is positioned on the upper outer side of the hoisting pile, and an overflow port is provided at the bottom of the hoisting pile.

[0017] Furthermore, a lifting ring is hinged to the upper part of the pile, and the handwheel is positioned below the rotation path of the lifting ring.

[0018] Furthermore, the lower end of the yarn base is provided with a positioning groove, which corresponds to the inner bottom of the dyeing cylinder.

[0019] Furthermore, the pressure plate is adjustablely mounted on the feed rod via bolts, and the end face of the yarn sleeve abuts against the end face of the pressure plate.

[0020] Furthermore, the pressure plate has a double-layer structure with a horizontal gap in the middle, and a longitudinal opening is also provided around the pressure plate.

[0021] The beneficial effects of this utility model are as follows: In use, by detaching each feeding rod from the yarn base, and adopting an inclined angle that is more adaptable and convenient for the operator, the yarn sleeves and pressure plates for dyeing are alternately fitted onto the feeding rods in sequence. Then, the drive unit drives the pressure ring to abut against the extended side end of each socket, so that each feeding rod is positioned on the yarn base, thereby quickly completing the placement process of all yarn sleeves. This avoids the fixed outer feeding rods affecting the process of the middle feeding rods fitting the yarn sleeves, thus improving the placement efficiency of the yarn sleeves.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0032] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] The first aspect of this utility model proposes a dyeing mechanism for spandex yarn, such as... Figure 1-6 As shown, the dyeing mechanism includes a yarn base 1 housed within the dyeing cylinder, a hanging post 2 at the center of the yarn base 1, several feeding rods 3 on the yarn base 1, and yarn sleeves 4 sequentially fitted onto each feeding rod 3. The hanging post 2 is a split-type structure. The dyeing mechanism also includes:

[0034] Pressure plates 5 are located on both sides of the yarn sleeve 4, and the pressure plates 5 are adjustablely mounted on the feed rod 3;

[0035] A socket 6 is located at the lower end of the feeding rod 3, and the side end of the socket 6 is extended.

[0036] Several plugs 7 are provided on the yarn base 1, and sockets 6 are inserted into the plugs 7;

[0037] A pressure ring 8 that mates with the extended side end of the socket 6;

[0038] A drive unit used to drive the pressure ring 8 to perform lifting and lowering actions.

[0039] In this embodiment, during use, the operator first removes each feeding rod 3 from the yarn base 1, then attaches the first pressure plate 5 from one end of the removed feeding rod 3 to the socket 6 at the other end. Then, using an angle that is more suitable and convenient for the operator, the operator alternately attaches the yarn sleeves 4 and pressure plates 5 to the feeding rod 3 in sequence until the last pressure plate 5 presses against the adjacent yarn sleeve 4. Then, the operator tightens each pressure plate 5 so that each yarn sleeve 4 on the feeding rod 3 is positioned.

[0040] After the pressure plates 5 are placed on all the feeding rods 3, the driving unit drives the pressure ring 8 to rise to a certain height so that each socket 6 is inserted into the corresponding plug 7 from the inside out. Finally, the driving unit drives the pressure ring 8 to fall until the lower end of the pressure ring 8 abuts against the extended side of each socket 6, so that each feeding rod 3 is positioned on the yarn base 1, thus completing the placement process of all the yarn sleeves 4. Finally, the external crane lifts the lifting pile 2 to place all the positioned yarn sleeves 4 into the dyeing cylinder filled with dye solution for dyeing treatment.

[0041] In this embodiment, as Figure 2 , Figure 3 , Figure 4 As shown, the upper and lower parts of the lifting pile 2 are both cylindrical structures, and the upper and lower parts of the lifting pile 2 are connected by bolts. The lower part of the lifting pile 2 is provided with a guide groove 9, which facilitates timely cleaning, maintenance or repair and replacement of the dyeing mechanism.

[0042] In this embodiment, as Figure 3 As shown, the drive unit includes:

[0043] The C-shaped connecting rod 10 is slidably disposed in the guide groove 9, and the lower end of the connecting rod 10 is fixedly connected to the pressure ring 8;

[0044] Rotate the threaded rod 11 located inside the lifting pile 2. The threaded rod 11 is threadedly connected to the middle of the connecting rod 10.

[0045] The handwheel 12 located at the top of the threaded rod 11 drives the threaded rod 11 to rotate within the lifting pile 2 by rotating the handwheel 12. Under the guidance of the guide groove 9, the connecting rod 10 can perform lifting and lowering actions, which in turn drives the pressure ring 8 connected at the lower end to lift and lower synchronously.

[0046] In this embodiment, as Figure 1 , Figure 2 As shown, the handwheel 12 is placed on the upper outer side of the pile 2, and the bottom of the pile 2 is provided with an overflow port.

[0047] In this embodiment, as Figure 3 As shown, a lifting ring 13 is hinged to the upper part of the pile 2, and a handwheel 12 is placed below the rotation path of the lifting ring 13. The external crane lifts the pile 2 through the lifting ring 13. Since the handwheel 12 is placed below the rotation path of the lifting ring 13, it avoids interference with the rotation of the lifting ring 13.

[0048] In this embodiment, as Figure 5 As shown, the lower end of the yarn base 1 is provided with a positioning groove 14, which corresponds to the inner bottom of the dyeing cylinder. This allows the yarn base 1 to be accurately positioned on the inner bottom of the dyeing cylinder, preventing the flow of dye liquor in the dyeing cylinder from causing the yarn base 1 to shake.

[0049] In this embodiment, as Figure 1 , Figure 6 As shown, the pressure plate 5 is adjustablely mounted on the feed rod 3 by bolts. The end face of the yarn sleeve 4 is pressed against the end face of the pressure plate 5. The fixed position of the pressure plate 5 on the feed rod 3 can be adjusted by tightening or loosening the bolts. Under the premise of ensuring that the end face of the yarn sleeve 4 is pressed tightly, it can adapt to various different models of yarn sleeves 4, and has greater versatility.

[0050] In this embodiment, as Figure 6 As shown, the pressure plate 5 has a double-layer structure and a horizontal gap 15 in the middle. The pressure plate 5 is also surrounded by longitudinal openings 16. The dye liquor in the dyeing cylinder can flow directly to the yarn sleeve 4 through the horizontal gap 15 and each longitudinal opening 16 to ensure the dyeing effect.
