Description

Technical Field

[0001] This utility model relates to the field of fabric desizing equipment, and more particularly to a desizing device for fabric printing and dyeing. Background Technology

[0002] During the fabric weaving process, sizing agents (such as starch, polyvinyl alcohol, etc.) are usually applied to improve the strength and smoothness of the warp yarns. However, the sizing agents must be removed through a desizing process before printing and dyeing, otherwise it will affect the adsorption of dyes and the dyeing effect.

[0003] Desizing requires the fabric to be placed in the desizing agent for 2-6 hours. In order to ensure that the fabric and the desizing agent are in full contact, the fabric needs to be placed in batches and multiple guide rollers are set in the desizing tank. The fabric is passed through the guide rollers one by one, so that the fabric is spread out and soaked in the desizing tank. However, after the fabric is soaked and desized, it absorbs the desizing liquid and its weight increases significantly. It is difficult to remove the desized fabric from the desizing tank, which also hinders the transfer of the fabric to the desizing tank in the next stage, thus affecting the desizing efficiency of the fabric.

[0015] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please refer to Figures 1 to 3 As shown, a desizing device for fabric printing and dyeing according to the present invention includes an unwinding mechanism, a desizing tank 4, an output mechanism, and an unfolding mechanism. The upper part of one end of the desizing tank 4 is provided with a fabric inlet, and the upper part of the other end of the desizing tank 4 is provided with a fabric outlet. The unwinding mechanism is provided on the outside of the desizing tank 4 near the fabric inlet, and the output mechanism is provided on the outside of the desizing tank 4 near the fabric outlet. The unfolding mechanism is provided inside the desizing tank 4. The unfolding mechanism includes several sets of unfolding components 3, and several sets of unfolding components 3 are arranged alternately from left to right inside the desizing tank 4. The unfolding assembly 3 includes a linear drive 301, a movable frame 302, and a support roller 303. The movable frame 302 is movably connected to the interior of the desizing tank 4. One side of the linear drive 301 is connected to the exterior of the desizing tank 4, and the other side of the linear drive 301 is linearly driven connected to one side of the movable frame 302. The support roller 303 is rotatably connected to the other side of the movable frame 302.

[0017] The working principle of this utility model is as follows: In actual production and use, when desizing of the fabric 16 is required, the roll of fabric 16 can be first installed onto the unwinding mechanism for unwinding. Then, one end of the fabric 16 is introduced into the desizing tank 4 through the inlet and passes through the middle of the desizing tank 4, and then connected to the output mechanism. When desizing is required, desizing agent is added into the desizing tank 4. Then, several unfolding components 3 in the desizing tank 4 are operated, so that the linear drive 301 drives the support roller 303 through the moving frame 302. The fabric 16 moves within the desizing tank 4, causing it to unfold in a wave-like pattern with the cooperation of several support rollers 303. This increases the soaking area of ​​the fabric 16 within the desizing tank 4. After desizing is completed, the linear drive 301 can be activated to reset the support rollers 303. Subsequently, the output mechanism and the unwinding mechanism are activated simultaneously, causing the output mechanism to output the desizing fabric 16 outside the desizing device for cleaning and to introduce the fabric 16 that needs to be desizing into the desizing tank 4.

[0018] Furthermore, the unwinding mechanism includes an unwinding frame 2, a first rotation drive 15, and an unwinding roller 1. The lower part of the unwinding frame 2 is connected to the outer surface of the desizing tank 4, and the unwinding roller 1 is rotatably connected to the upper part of the unwinding frame 2. The first rotation drive 15 is drivenly connected to the unwinding roller 1.

[0019] As can be seen from the above description, when it is necessary to unwind the roll of fabric 16, the fabric 16 can be installed on the unwinding roller 1, and then the first rotation drive 15 is operated so that the first rotation drive 15 drives the fabric 16 to unwind through the unwinding roller 1, thereby allowing the fabric 16 to be input into the desizing tank 4 for desizing.

[0020] Furthermore, the output mechanism includes a drain box 17, two fabric conveying rollers 11, two meshing wheels 7, and a second rotation drive 5. The drain box 17 is connected to the outer surface of the desizing tank 4. Output ports 6 are provided on both sides of the drain box 17, and the fabric outlet is connected to the output ports 6. Two fabric conveying rollers 11 are rotatably connected inside the drain box 17. One fabric conveying roller 11 is positioned above the other fabric conveying roller 11, and a gap is provided between the fabric conveying rollers 11. One end of each fabric conveying roller 11 is provided with a meshing wheel 7, and the meshing wheels 7 mesh with each other. The second rotation drive 5 is rotatably driven connected to the other end of one of the fabric conveying rollers 11.

[0021] As can be seen from the above description, when the fabric 16 that needs to be desized is output, the fabric 16 passes through the gap between the conveying rollers 11, and the second rotation drive 5 is activated, causing the second rotation drive 5 to drive one conveying roller 11 to rotate. Then, one conveying roller 11 drives another conveying roller 11 to rotate through the meshing wheel 7. With the cooperation of the conveying rollers 11, the fabric 16 in the desizing tank 4 is discharged. At the same time as the discharge, the excess desizing agent of the fabric 16 is squeezed by the conveying rollers 11 and discharged into the drain box 17 for collection.

[0022] Furthermore, a drain outlet 9 is provided at the lower part of the drain box 17.

[0023] As can be seen from the above description, it is beneficial for the desizing agent in the drain box 17 to be discharged more effectively through the drain outlet 9.

[0024] Furthermore, it also includes a shut-off valve. The upper part of the desizing tank 4 is provided with a replenishing port 14, and the lower part of the desizing tank 4 is provided with a discharge port 12. The shut-off valve is provided inside the discharge port 12.

[0025] As can be seen from the above description, after the fabric 16 is installed, desizing agent can be added to the desizing tank 4 through the replenishment port 14. When it is necessary to discharge the desizing agent in the desizing tank 4, the shut-off valve can be opened to open the discharge port 12, so that the desizing agent can be discharged through the discharge port 12.

[0026] Furthermore, an operation port is provided in the middle of the deslurry tank 4, and a sealing door 13 is detachably connected to the operation port.

[0027] As can be seen from the above description, when it is necessary to install the fabric 16, the sealing door 13 on the operating port can be opened, so that the operator can better pass the fabric 16 through the operating port through the middle of the desizing tank 4 and connect it with the output mechanism. After the installation is completed, the operating port is closed through the sealing door 13, and then desizing agent is added into the desizing tank 4 through the replenishment port 14.

[0028] Furthermore, it also includes support feet 10, and several support feet 10 are fixedly connected to the bottom of the deslurry tank 4.

[0029] As can be seen from the above description, it is beneficial to make the device operate more stably and to better install the linear drive component 301.

[0030] Furthermore, it also includes a PLC controller 8, which is electrically connected to the unwinding mechanism, the output mechanism, and the unfolding mechanism.

[0031] As can be seen from the above description, it is beneficial to adjust the parameters of the desizing device through the PLC controller 8, and to make it more convenient for operators to operate the desizing device. Example 1
