Description

Technical Field

[0001] This utility model relates to the technical field of trademark tape production equipment, and in particular to a trademark tape raw material dyeing device. Background Technology

[0002] Label tape is a type of textile used to display trademarks or product information on clothing, shoes, bags, packaging tapes, and other products. It requires a dyeing process during its production.

[0003] The prior art, such as the invention patent with publication number CN118390260A entitled "Integrated Washing and Dyeing Equipment and Method for Polyester Trademark Strips", includes a base, on which a washing tank, a drying tank and a dyeing tank are sequentially installed in sequence. A door panel is movably installed at the front of the drying tank. A circulation structure is provided on the upper part of the washing tank. The circulation structure includes two first fixed seats and two second fixed seats, which are symmetrically installed on the upper part of the washing tank. A first rotating drum is rotatably connected between the two first fixed seats.

[0004] Although the above-mentioned device can clean the raw materials, in actual use, because the raw materials are continuous long strips, they need to be continuously wound up and down inside the equipment, which is cumbersome. In addition, the existing dyeing equipment can only perform one dyeing per process. The pigment and fiber are weakly bonded in a single dyeing, resulting in low color fastness indicators such as lightfastness and wash fastness, and a short service life. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the present invention provides a dyeing device for trademark tape raw materials, which solves the technical problems mentioned in the background art regarding the cumbersome installation of raw materials and poor color fastness of existing dyeing devices.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A dyeing device for trademark strip raw materials includes a dyeing tank, a first dyeing chamber and a second dyeing chamber are provided in the dyeing tank, a coagulation chamber is provided between the first dyeing chamber and the second dyeing chamber, the bottoms of the first dyeing chamber and the second dyeing chamber are connected, tensioning components for tensioning the raw materials are provided on the first dyeing chamber and the second dyeing chamber, a first motor for simultaneously driving the first tensioning component and the second tensioning component is provided on the dyeing tank, a plurality of hot pressure rollers for heat treatment of the upper and lower surfaces of the raw materials are rotatably provided in the coagulation chamber, a solidifying component is also provided at the bottom of the inner side of the coagulation chamber, a swirling component is provided at the connection between the first dyeing chamber and the second dyeing chamber, and a second motor for simultaneously driving the solidifying component and the swirling component is provided at the bottom of the dyeing chamber.

[0008] Working principle:

[0009] This device is a dyeing device for trademark tape raw materials, mainly used for dyeing trademark tape raw materials.

[0010] During installation, the raw material is simply passed through the first dyeing chamber, the coagulation chamber, and the second dyeing chamber in sequence, and finally extends out from the second dyeing chamber and is connected to the subsequent drying device or tightening device. When passing through the coagulation chamber, the raw material only needs to be wrapped around two hot pressure rollers. After that, the first click is operated to make the tensioning component drive the raw material passing through the first dyeing chamber and the second dyeing chamber to press downward, so that the raw material comes into contact with the dye in the first dyeing chamber and the second dyeing chamber for dyeing.

[0011] In use, the raw material is first dyed in the first dyeing chamber, then extends out of the first dyeing chamber and into the coagulation chamber. The dye penetrates further into the raw material through the hot press rollers and coagulating elements in the coagulation chamber. It then extends out of the coagulation chamber and enters the second dyeing chamber for secondary dyeing, and finally extends out of the second dyeing chamber.

[0012] Beneficial effects achieved:

[0013] First, it is equipped with a first dyeing chamber and a second dyeing chamber, which allows the raw materials to be dyed twice, preventing the dye on the raw materials from fading and increasing the service life of the label tape.

[0014] Secondly, it is equipped with a condensation chamber, which can effectively further combine the raw materials and dyes, making it easier to dye the raw materials again in the future and improving the service life of the product.

[0015] Third, it is equipped with a tensioning element, which can effectively tighten the passing raw materials. This not only facilitates installation by the staff, but also effectively brings the raw materials into contact with the dye for dyeing.

[0016] Secondary dyeing can strengthen the bond between dye and fabric, enhance color fastness indicators such as lightfastness and wash fastness, and improve the product's lifespan. Secondary dyeing can also adjust the fabric's brightness, saturation, and other visual characteristics, creating a richer and more elegant visual effect. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example:

[0025] Reference Figures 1-5 This utility model relates to a dyeing device for trademark strips, comprising a dyeing tank 1, a first dyeing chamber 2 and a second dyeing chamber 3 within the dyeing tank 1, a coagulation chamber 4 between the first dyeing chamber 2 and the second dyeing chamber 3, and bottom connections between the first dyeing chamber 2 and the second dyeing chamber 3. The first dyeing chamber 2 and the second dyeing chamber 3 are equipped with tensioning components for tightening the raw material, such as... Figure 1 and Figure 2 As shown, the tensioning component includes two fixed frames 8, two screws 9, two mounting sleeves 10, and two tension rollers 11. The two fixed frames 8 are respectively fixed to the top of the first dyeing chamber 2 and the second dyeing chamber 3. The two screws 9 are rotatably mounted on the two fixed frames 8, with their bottoms pointing vertically downwards and rotatably connected to the bottoms of the first dyeing chamber 2 and the second dyeing chamber 3, respectively. The first dyeing chamber 2 and the second dyeing chamber 3 are each provided with two vertical grooves 12. The two mounting sleeves 10 are slidably mounted in the two grooves 12 and threaded onto the two screws 9. The two tension rollers 11 are rotatably mounted on the two mounting sleeves 10. The dyeing tank 1 is equipped with a first motor 6 for simultaneously driving the first and second tensioning components. Figure 3As shown, a first pulley 13 is provided between the output end of the first motor 6 and one of the screws 9, and a first belt 14 is fitted onto the two first pulleys 13. A second pulley 15 is provided between the output end of the first motor 6 and the other screw 9, and a second belt 16 is fitted onto the two second pulleys 15. This arrangement can effectively drive the first pulleys 13 and 15 to rotate via the first motor 6. When the first pulleys 13 and 15 rotate, they will drive the two screws 9 to rotate via the first belt 14 and the second belt 16, and cause the mounting sleeve 10 and the tension roller 11 located on the screws 9 to move vertically along the screws 9.

[0026] like Figure 1 As shown, the coagulation chamber 4 is equipped with several hot pressure rollers 29 for heat treatment of the upper and lower surfaces of the raw material. This arrangement can increase the contact temperature between the raw material and the dye, thereby accelerating the penetration and adsorption speed of the dye in the raw material. The higher temperature can increase the movement speed and diffusion coefficient of the dye molecules, promoting the dye to migrate into the fabric more quickly.

[0027] like Figure 1 As shown, a second motor 7 is installed at the bottom of the dyeing tank, and a coagulation device is also installed at the bottom of the inner side of the coagulation tank 4. The coagulation device includes two guide vanes 17 and several fan blades 18. The two guide vanes 17 are fixed inside the coagulation tank 4 and located on both sides of the raw material. The tops of the two guide vanes 17 are provided with arc-shaped air guide edges 20, which allows some air force to be blown towards the upper surface of the raw material, improving the degree of bonding between the upper surface of the raw material and the dye. A rotating shaft 19 is fixed at the output end of the second motor 7. The rotating shaft 19 passes through the dyeing tank 1 and the coagulation tank 4 in sequence and extends into the coagulation tank 4. Several fan blades 18 are evenly fixed at one end of the rotating shaft 19 that extends into the coagulation tank 4. An isolation net 21 is provided inside the coagulation tank 4 and above the fan blades 18. Several ventilation holes 22 for conveying hot air are opened on the side wall of the coagulation tank 4 and below the isolation net 21. These ventilation holes 22 can be connected to the external drying device.

[0028] like Figure 1 As shown, a swirling element is provided at the connection between the first dyeing chamber 2 and the second dyeing chamber 3. The swirling element includes a fixed sleeve 23 and several rotating plates 24. The fixed sleeve 23 is fixed on the rotating shaft 19 and located between the dyeing tank 1 and the coagulation chamber 4. The several rotating plates 24 are evenly fixed on the fixed sleeve 23. This arrangement allows the fixed sleeve 23 and rotating plates 24 to rotate simultaneously within the dyeing tank 1 when the second motor 7 drives the fan blades 18 to rotate, thus keeping the dye in the dyeing tank 1 flowing and preventing sedimentation.

[0029] like Figure 1 and Figure 5As shown, a cleaning component for removing excess dye from raw materials is provided between the first dyeing tank 2 and the coagulation tank 4. The cleaning component includes a mounting frame 25, two cleaning rollers 26, a lifting frame 27, and several lifting cylinders 28. The mounting frame 25 is fixed to the dyeing tank 1 and located between the first dyeing tank 2 and the coagulation tank 4. One cleaning roller 26 is rotatably mounted on the mounting frame 25, and the other cleaning roller 26 is rotatably mounted on the lifting frame 27, with the two cleaning rollers corresponding to each other. Several lifting cylinders 28 are fixed to the top of the mounting frame 25, with their extension and retraction ends pointing vertically downwards and fixedly connected to the top of the lifting frame 27. This arrangement facilitates the installation of raw materials when the lifting cylinders 28 are raised. It is worth noting that this device also includes multiple transfer rollers, with the raw materials located above these rollers for transport and conveying.

[0030] Working principle:

[0031] During installation, the raw material is simply passed sequentially through the first dyeing chamber 2, the coagulation chamber 4, and the second dyeing chamber 3, finally exiting from the second dyeing chamber 3 and connecting to the subsequent drying or tightening device. When passing through the coagulation chamber 4, the raw material only needs to be wrapped around the two hot press rollers 29, making installation convenient. After installation, the first motor 6 is operated to drive the first pulley 13 and the second pulley 15 to rotate. When the first pulley 13 and the second pulley 15 rotate, the first belt 14 and the second belt 16 drive the two screws 9 to rotate, causing the mounting sleeve 10 and the tension roller 11 located on the screws 9 to move vertically along the screws 9, causing the raw material passing through the first dyeing chamber 2 and the second dyeing chamber 3 to be pressed downwards, so that the raw material comes into contact with the dye in the first dyeing chamber 2 and the second dyeing chamber 3 for dyeing. At the same time, several lifting cylinders 28 are operated to drive the lifting frame 27 and one of the cleaning rollers 26 to move to the other cleaning roller 26, so that the raw material is located between the two cleaning rollers 26.

[0032] In use, the raw material is first dyed in the first dyeing chamber 2, then extends out of the first dyeing chamber 2 and into the coagulation chamber 4. When it passes through the hot pressure roller 29 in the coagulation chamber 4, the second motor 7 is turned on and drives the fan blade 18 to rotate. Hot air is delivered into the coagulation chamber 4 through the external drying device, so that the raw material passing through the coagulation chamber 4 is further combined with the dye. Then it enters the second dyeing chamber 3 for secondary dyeing, and finally extends out of the second dyeing chamber 3.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
