Description

Technical Field

[0001] This utility model relates to the field of denim production technology, and in particular to an auxiliary dyeing device for denim production. Background Technology

[0002] Jeans are durable and dirt-resistant. They initially appeared in the public eye as workwear, but now they are gradually becoming popular in the field of casual wear. Moreover, people's demand for the fashionable appearance of jeans is increasing day by day. Since the colors of ordinary jeans are relatively limited, they are spray-dyed during the production process to enrich the colors of jeans.

[0003] Currently, dyeing jeans requires manual operation by holding the dyeing machine and moving it up and down over the jeans. However, the dye has a pungent odor and contains harmful substances. The ventilation system inside the factory is ineffective, affecting the work experience and health of the workers. Furthermore, the processing height is currently fixed, requiring users to squat down to dye the lower part of the jeans. This repeated squatting and standing up over a long period of time results in a heavy workload for the workers and affects processing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary spray dyeing device for denim production.

[0005] An embodiment of this utility model provides an auxiliary dyeing device for denim production, comprising:

[0006] A base is provided, with a processing cabinet fixedly connected to its upper surface. A lifting assembly, an exhaust assembly, and a processing assembly are installed on the processing cabinet. A placement device is installed on the lifting assembly. The processing assembly includes a fixed shell fixedly connected to the side wall of the processing cabinet, with an exhaust pipe connected to the fixed shell. Multiple connecting frames slide through the fixed shell, and activated carbon plates are fixedly installed on the inner walls of each connecting frame. Multiple fixing components are installed on the upper surface of the fixed shell, each corresponding to one of the connecting frames. Each fixing component includes a connecting shell fixedly connected to the fixed shell, with a sliding plate slidably connected inside the connecting shell. A locking block is fixedly connected to the sliding plate. Multiple springs are fixedly connected to the inner wall of the connecting shell, and the sliding plate is fixedly connected to the springs.

A slot is formed on the side wall of the connecting frame, matching the slot and the locking block, which is wedge-shaped. The exhaust assembly is installed on the fixed shell.

[0007] Furthermore, the lifting assembly includes two lifting slots respectively opened on the two side walls of the processing cabinet, and a lifting plate is slidably connected in both lifting slots. A threaded rod is rotatably connected to the inner wall of one of the lifting slots, and the threaded rod threaded through the lifting plate. A servo motor is fixedly connected to the upper end face of the processing cabinet, and the rotating end of the servo motor is fixedly connected to the threaded rod. A rotating disk is rotatably connected to the lower end face of the lifting plate, and the placement device is installed on the rotating disk. A rotating assembly is installed on the processing cabinet.

[0008] Furthermore, the rotating assembly includes a splined shaft rotatably connected to the inner wall of the processing cabinet, the splined shaft passing through a lifting plate, a rotating gear rotatably connected to the upper surface of the lifting plate, the rotating gear meshing with the splined shaft, a first sprocket fixedly connected to the upper surface of the rotating gear, a second sprocket rotatably connected to the upper surface of the lifting plate, the second sprocket fixedly connected to a rotating disk, and a chain drive between the first sprocket and the second sprocket. A handle is fixedly connected to the lower surface of the splined shaft.

[0009] Furthermore, the air extraction assembly includes multiple connecting pipes installed on the processing cabinet, multiple air collection hoods are fixedly installed on the inner wall of the processing cabinet, the multiple air collection hoods are installed on the multiple connecting pipes, and the multiple connecting pipes are connected to a common air supply pipe. A variable frequency fan is fixedly installed on the side wall of the processing cabinet, the air intake end of the variable frequency fan is connected to the air supply pipe, and the air outlet end of the variable frequency fan is connected to the fixed shell.

[0010] Furthermore, a bracket is fixedly connected to the upper surface of the lifting plate, and the chain slides on the bracket.

[0011] Furthermore, a protective shell is fixedly connected to the upper surface of the processing cabinet, and the protective shell is matched with the servo motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. When workers are performing the spray dyeing work, the variable frequency fan starts to work, and the gas generated by the dye is absorbed into the fixed shell through the gas collection hood. The activated carbon plate adsorbs and discharges the odor and harmful impurities in the gas, which not only promotes the uniform distribution and rapid drying of the dye, but also helps to reduce the residue of harmful substances and ensure the safety of the processing environment.

[0014] 2. When the activated carbon plate needs to be replaced, the user can pull the lever and then pull the connecting bracket to remove the connecting bracket, which makes it easy for the user to install and remove the activated carbon plate and improves the portability of the device.

[0015] 3. After the user finishes dyeing the upper part of the jeans, the servo motor starts working, causing the lifting plate to rise, which raises the height of the lower part of the jeans, making it easier for the user to dye and improving the portability of the device.

The side wall of the connecting frame 4 has a slot that matches the locking block 7. The locking block 7 is wedge-shaped. The air extraction component is installed on the fixing shell 3.

[0023] The lifting assembly includes two lifting slots respectively opened on the two side walls of the processing cabinet 2. A lifting plate 9 is slidably connected in both lifting slots. A threaded rod 10 is rotatably connected to the inner wall of one of the lifting slots. The threaded rod 10 is threaded through the lifting plate 9. A servo motor 11 is fixedly connected to the upper end face of the processing cabinet 2. A protective shell is fixedly connected to the upper end face of the processing cabinet 2. The protective shell matches the servo motor 11 to prevent the servo motor 11 from being damaged by external interference.

A placement device 12 is installed on the rotating disk. A rotating assembly is installed on the processing cabinet 2.

[0024] The rotating assembly includes a splined shaft 13 rotatably connected to the inner wall of the processing cabinet 2. The splined shaft 13 passes through the lifting plate 9. A rotating gear 14 is rotatably connected to the upper end face of the lifting plate 9. The rotating gear 14 and the splined shaft 13 mesh with each other. A first sprocket is fixedly connected to the upper end face of the rotating gear 14. A second sprocket is rotatably connected to the upper end face of the lifting plate 9. The second sprocket is fixedly connected to the rotating disk. The first sprocket and the second sprocket are driven by a chain 15. A handle 16 is fixedly connected to the lower end face of the splined shaft 13. A bracket 20 is fixedly connected to the upper end face of the lifting plate 9. The chain 15 slides on the bracket 20.

It will not be elaborated here. The air intake end of the variable frequency fan 19 is connected to the air supply pipe, and the air outlet end of the variable frequency fan 19 is connected to the fixed shell 3.

[0026] The detailed working process of this utility model is as follows:

[0027] First, the user places the jeans on the placement device 12, followed by the dyeing process. During dyeing, the variable frequency fan 19 starts working, drawing the dye-generated gas into the fixed housing 3 through the gas collection hood 18. The activated carbon plate 5 inside the fixed housing 3 adsorbs odors and harmful impurities from the gas. The treated gas is then discharged through the exhaust pipe, ensuring air circulation within the processing cabinet 2. This not only promotes uniform dye distribution and rapid drying but also helps reduce harmful residues, ensuring a safe processing environment. When the activated carbon plate 5 needs to be replaced, the user pulls the lever, the spring 8 retracts, and the locking block 7 can be removed from the slot on the connecting frame 4. Then, pulling the connecting frame 4 allows it to be pulled out, facilitating the installation and removal of the activated carbon plate 5 and improving the portability of the device. After the user finishes dyeing the upper part of the jeans, the servo motor 11 starts working, and the threaded rod 10 starts rotating, which raises the lifting plate 9, increasing the height of the lower part of the jeans for easier dyeing and improving the portability of the device. Furthermore, by rotating the handle 16, the user can rotate the rotating disk through the cooperation of the spline shaft 13, rotating gear 14, first sprocket, second sprocket, and chain 15, thereby rotating the jeans and allowing the user to adjust the dyeing surface of the jeans, further improving the portability of the device.
