Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing steaming box technology, specifically to a continuous tight guide roller steaming box for fabric printing and dyeing. Background Technology

[0002] Fabric dyeing and finishing, also known as finishing and finishing, is a processing method that encompasses pretreatment, dyeing, printing, finishing, washing, and more. In fabric dyeing and finishing, steaming ovens are used for setting the color. These ovens utilize the heat and humidity of steam to allow dyes to penetrate the fibers more effectively, achieving uniform dyeing. Simultaneously, steam also helps to set the shape of the textiles, maintaining their dimensional stability.

[0003] There are two types of steaming boxes. One type uses a special rack to place the fabric on, and then the rack is pushed into the steaming box for shaping. The other type is continuous, where the fabric is fed into the steaming box, especially the horizontal steaming box, by a special conveyor. The fabric is steam-shaped as it moves through the steaming box. This type of steaming box requires tension rollers to adjust the tension of the fabric during conveying. Especially under the principle of thermal expansion and contraction, the tension adjustment range of the tension rollers will be greater than the tension range at room temperature. Currently, the tension rollers are mostly adjusted by springs. However, as the springs are continuously compressed, the rebound force is also greater, making it impossible to output a balanced and stable tension force. Utility Model Content

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A continuous tension roller steamer for fabric printing and dyeing includes a box body. Multiple guide rollers and multiple tension rollers are installed at the top and bottom of the box body, respectively. Each tension roller has a bearing seat two at both ends. A vertical rod is fixedly installed at the bottom of the bearing seat two. A sleeve is fixedly installed on the outside of the vertical rod. The vertical rod is partially fitted into the sleeve. Dense permanent magnets two are evenly installed on the inner wall of the sleeve. Dense permanent magnets one are evenly installed on the outer wall of the vertical rod. Permanent magnets one and two are like-pole repulsive.

[0006] Furthermore, a second fixing beam is fixedly installed on the inner wall of the box corresponding to the second bearing seat. The second bearing seat is located above the second fixing beam, and a fixing seat is fixedly installed on the top of the second fixing beam directly opposite the second bearing seat. The sleeve is installed on the fixing seat directly opposite the position of the upright. The second fixing beam provides support and fixation for the fixing seat, making the sleeve independent and staggered, thus meeting the requirements for the vertical movement of the upright.

[0007] Furthermore, fabric inlets and outlets are pre-set on the left and right sides near the top of the housing. Each guide roller has a bearing seat at both ends, and a fixing beam is fixedly installed on the inner wall of the housing corresponding to the bearing seat. The bearing seat and the fixing beam are fixedly installed. The guide rollers are fixed and are responsible for guiding the printed fabric. The printed fabric must pass through the guide rollers when entering and exiting the housing.

[0008] Furthermore, a main steam input pipe is installed on the top of the housing, and two branch steam input pipes are fixedly connected to the bottom of the main steam input pipe. The branch steam input pipes are connected to the inside of the housing, and the printed and dyed fabric passes through the guide rollers and tension rollers inside the housing and enters and exits the housing through the fabric inlet and outlet on both sides of the housing. The use of an independent steam equipment for steam supply input meets the centralized production needs of the factory.

[0009] Furthermore, multiple steam output nozzles facing the printed fabric are installed on the front and rear inner walls of the housing. Fixing frames are fixedly installed on the front and rear outer walls of the housing corresponding to the positions of the respective steam output nozzles. Two steam input branch pipes extend to the corresponding fixing frames, and diffuser covers are fixedly installed between the fixing frames and the steam input branch pipes. The steam output nozzles are connected to the diffuser covers. The main steam input pipe, steam input branch pipes, and steam output nozzles work together to form a decentralized steam input, which can accelerate the diffusion of steam within the housing and help ensure the steam temperature and concentration at various locations within the housing.

[0010] Furthermore, the nozzles of the steam output nozzles on the front and rear inner walls of the housing are respectively angled towards both sides of the printed and dyed fabric. This angled blowing method ensures that the steam can directly contact the printed and dyed fabric, which can accelerate the setting speed.

[0011] Furthermore, a water-guiding slope is pre-set at the bottom of the box body, and a water collection trough is pre-set at the bottom of the slope. A drain pipe is fixedly installed on the rear side of the box body corresponding to the water collection trough, and a valve is installed on the drain pipe. The water-guiding slope can collect condensed water droplets, which are then periodically discharged through the drain pipe to prevent water accumulation inside the box body.

[0012] Furthermore, the drain pipe between the valve and the housing has an opening at its top, where an arc-shaped cover is placed. Multiple filter screens are fixedly installed on the concave surface of the arc-shaped cover, with the mesh size of the screens increasing sequentially from the housing towards the valve. A handle is fixedly installed at the center of the top of the arc-shaped cover, and pipe clips are fitted onto the drain pipe on both sides of the handle. The filter screens block lint, fabric fibers, and debris. The increasing mesh size of the multiple screens disperses the blocking amount from each screen, preventing blockage caused by concentrated buildup on the first screen, extending the cleaning interval, and reducing maintenance frequency.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the principle of attraction between opposite magnetic fields and repulsion between like magnetic fields to support the tensioning roller. When the tensioning roller is tensioned, the supporting force output by the permanent magnet is relatively balanced and stable, so that the tensioning roller outputs a relatively balanced and stable tension force on the printed and dyed fabric at different positions.

[0015] 2. In this utility model, by angled steam output nozzles toward both sides of the printed and dyed fabric, steam can be directly sprayed onto both sides of the printed and dyed fabric when input, which can accelerate the fabric setting.

[0016] 3. In this utility model, the combination of a water guide ramp, a water collection trough, and a drain pipe can quickly and easily collect and drain condensed water droplets inside the box, effectively preventing water accumulation inside the box.

[0017] 4. In this utility model, by setting a filter screen on the drain pipe, the thread ends, fabric fibers and debris in the discharged water can be blocked and filtered, and it is fixed by the arc-shaped cover plate, which facilitates cleaning and replacement. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] This application provides a continuous tension roller steamer for fabric printing and dyeing, mainly solving the problem that the spring tension rollers in current steamers cannot output a balanced and stable tension force, and provides the following technical solution, which will be combined with... Figure 1 - Figure 6 Please provide a detailed explanation:

[0027] A continuous tension roller steamer for fabric printing and dyeing includes a box body 1. Fabric inlet and outlet 26 are preset on the left and right sides near the top. Multiple guide rollers 7 and multiple tension rollers 8 are installed in the box body 1 near the top and bottom. Each guide roller 7 has a bearing seat 9 installed at both ends. A fixing beam 10 is fixedly installed on the inner wall of the box body 1 corresponding to the bearing seat 9. The bearing seat 9 and the fixing beam 10 are fixedly installed.

[0028] Each tension roller 8 has a bearing seat 2 11 installed at both ends. A fixing beam 2 14 is fixedly installed on the inner wall of the housing 1 corresponding to the bearing seat 2 11. The bearing seat 2 11 is located above the fixing beam 2 14. A vertical rod 12 is fixedly installed at the bottom of the bearing seat 2 11. A fixing seat 13 is fixedly installed at the top of the fixing beam 2 14 directly opposite the bearing seat 2 11. A sleeve 15 is fixedly installed on the fixing seat 13 directly opposite the vertical rod 12. The vertical rod 12 is partially fitted into the sleeve 15. Dense permanent magnets 2 17 are evenly installed on the inner wall of the sleeve 15. Dense permanent magnets 16 are evenly installed on the outer wall of the vertical rod 12. Permanent magnets 16 and permanent magnets 2 17 are close to each other. Permanent magnets 16 and permanent magnets 2 17 repel each other because of their similar polarity.

[0029] A steam input main pipe 2 is installed on the top of the box 1. Two steam input branch pipes 3 are fixedly connected to the bottom of the steam input main pipe 2. The steam input branch pipes 3 are connected to the inside of the box 1. The printed and dyed fabric 27 enters and exits the box 1 through the fabric inlet and outlet 26 on both sides of the box 1. The printed and dyed fabric 27 simultaneously passes through the guide roller 7 and tension roller 8 inside the box 1.

[0030] This steaming box is a steaming box without a conveyor mechanism. It is used in conjunction with an existing fabric conveyor. First, the printed and dyed fabric 27 is extended into the box 1 through the fabric inlet and outlet 26 on one side of the box 1. Then, it passes through the guide roller 7 on the upper side and the tension roller 8 on the lower side of the box 1 in sequence. Then, it is output to the fabric conveyor through the fabric inlet and outlet 26 on the other side of the box 1. The steam input main pipe 2 is connected to the existing steam equipment. The steam is input into the box 1 through the steam input main pipe 2 and the steam input branch pipe 3. The steam can then come into contact with the printed and dyed fabric 27 for steam setting.

[0031] Meanwhile, the existing fabric conveyor transports the dyed fabric 27 to form a continuous steam treatment. The dyed fabric 27 inside the housing 1 is affected by the conveying pressure of the fabric conveyor and internal thermal expansion. When the fabric becomes longer, the upward pulling force of the dyed fabric 27 on the tension roller 8 weakens. Simultaneously, due to the weight of the tension roller 8, after the permanent magnet 16 overcomes the repulsive force of each layer of permanent magnet 17, the upright rod 12 moves downward within the sleeve 15, thus tightening the dyed fabric 27. When the fabric becomes shorter, due to the upward pulling effect of the fabric, the tension roller 8 moves upward, and after the permanent magnet 16 continues to overcome the repulsive force of each layer of permanent magnet 17, the upright rod 12 moves upward within the sleeve 15, tightening the dyed fabric 27 again. Because... The number of repulsions between permanent magnet 16 and permanent magnet 17 is always the same. Therefore, no matter what height the upright 12 is at, the repulsion force between them remains stable. When permanent magnet 16 moves and breaks through each layer of permanent magnet 17, the maximum resistance is also maintained within a certain range, thus making the tension output of tension roller 8 stable and balanced. Considering the steam temperature of the dyeing fabric 27, both permanent magnet 16 and permanent magnet 17 are neodymium iron boron magnets with a Curie temperature usually between 310℃ and 400℃. For 28UH to 35UH grades, the temperature does not exceed 160℃; for 28EH to 35EH grades, the temperature does not exceed 180℃. Alternatively, samarium cobalt magnets with higher maximum operating temperatures can be used to increase costs.

[0032] In some embodiments, multiple steam output nozzles 6 facing the dyed fabric 27 are installed on the front and rear inner walls of the housing 1. The nozzles of the steam output nozzles 6 on the front and rear inner walls are respectively obliquely arranged towards the two sides of the dyed fabric 27. Fixing frames 5 are fixedly installed on the front and rear outer walls of the housing 1 corresponding to the positions of the front and rear steam output nozzles 6. Two steam input branch pipes 3 extend to the fixing frames 5 at the corresponding positions. A diffuser hood 4 is fixedly installed between the fixing frames 5 at the corresponding positions and the steam input branch pipes 3. The steam output nozzles 6 are connected to the diffuser hood 4.

[0033] The steam in the steam input branch pipe 3 is diffused by the diffuser hood 4 and then sprayed from each steam output nozzle 6 onto the printed fabric 27 inside the box 1. Since the front and rear steam output nozzles 6 are respectively facing the two sides of the printed fabric 27, steam can be sprayed directly onto both sides of the printed fabric 27 for rapid shaping.

[0034] In some embodiments, a water guiding slope 20 is pre-set at the bottom of the box body 1, a water collection trough 21 is pre-set at the bottom of the water guiding slope 20, a drain pipe 18 is fixedly installed on the rear side of the box body 1 corresponding to the position of the water collection trough 21, and a pipe valve 19 is installed on the drain pipe 18.

[0035] When steam condenses into water droplets inside the housing 1, the water droplets will eventually collect at the bottom of the housing 1. The water guide ramp 20 can guide the water droplets into the water collection tank 21 for collection. Then, the pipe valve 19 can be opened periodically to drain the internal water.

[0036] In some embodiments, the top of the drain pipe 18 between the valve 19 and the housing 1 is open, and an arc-shaped cover plate 22 is placed at the opening. The arc-shaped cover plate 22 is set to half the circumference of the drain pipe 18. Multiple filter screens 23 are fixedly installed on the arc-shaped concave surface of the arc-shaped cover plate 22. The mesh count of the multiple filter screens 23 increases sequentially from the housing 1 towards the valve 19. A handle 25 is fixedly installed at the middle position of the top of the arc-shaped cover plate 22. Pipe buckles 24 are fitted on the arc-shaped cover plates 22 and the drain pipe 18 on both sides of the handle 25.

[0037] The filter screen 23 blocks and filters fabric fibers, thread ends, and debris in the discharged water. After draining the water periodically, open the pipe buckle 24 and then remove the arc-shaped cover plate 22 from the handle 25. Clean the filtered material on the filter screen 23 and put it back or replace it with a new one. The arc-shaped cover plate 22 is sealed at the contact points with the drain pipe 18 to prevent water leakage.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
