Description

Technical Field

[0001] The present application relates to the field of fabric printing, and in particular to a pre-processing device for fabric printing. Background Art

[0002] The original cloth or grey cloth contains a lot of impurities, oils, dirt, etc. In order to remove impurities and improve the quality of the fabric, pre-treatment must be carried out before dyeing, printing and finishing. Good pre-treatment of the fabric is the basis and guarantee for subsequent processes. Before printing, the fabric needs to be sprayed with pre-treatment liquid.

[0003] When the fabric is sprayed with the pretreatment liquid, due to the wrinkles on the fabric, it is difficult to spray the pretreatment liquid on the wrinkles, and the pretreatment liquid is unevenly distributed on the fabric, thereby affecting the subsequent printing effect of the fabric. Utility Model Content

[0004] In order to solve the problem that wrinkles exist on the cloth, the wrinkles are difficult to spray when spraying the pretreatment liquid, and the uneven distribution of the pretreatment liquid affects the subsequent printing of the cloth, the present application provides a pretreatment device for cloth printing.

The edge-pulled cloth is expanded by the expanding roller, and the expanded cloth is transported to the spraying mechanism to be sprayed with pretreatment liquid. After being treated by the edge-pulling mechanism and the expanding roller, there are fewer wrinkles on the cloth, and the pretreatment liquid is evenly distributed on the cloth.

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application embodiment discloses a pre-processing device for fabric printing, referring to Figure 1 , including a frame 1, on which a plurality of cloth guide rollers 11 are arranged, and the cloth guide rollers 11 are distributed parallel to each other. A hair suction component 2 is arranged on one side of the frame 1, and the cloth is wound around the cloth guide rollers 11 and is sucked by the hair suction component 2.

[0034] Reference Figure 1 and Figure 2 A wrinkle removal component is arranged on one side of the hair suction component 2 on the frame 1, and the wrinkle removal component includes a drawing mechanism 3 and an expansion roller 4. The drawing mechanism 3 is arranged on the frame 1 and is located on both sides of the cloth width direction. The drawing is performed by the drawing mechanisms 3 on both sides to reduce wrinkles on the cloth.

[0035] Reference Figure 1 and Figure 2 The expansion roller 4 is rotatably mounted on the frame 1 and is located on one side of the edge stretching mechanism 3. The edge stretched fabric is expanded by the expansion roller 4. A spray mechanism 5 is provided on the frame 1 on one side of the expansion roller 4. The fabric is transported to the spray mechanism 5 for spraying of the pretreatment liquid. The fabric treated by the edge stretching mechanism 3 and the expansion roller 4 has fewer wrinkles, and the pretreatment liquid is evenly distributed on the fabric.

[0036] Reference Figure 1 and Figure 2 The hair suction assembly 2 includes a bristle rod 21 and a suction mechanism 22. A collecting cover 12 is arranged on one side of the frame 1 along the width direction of the frame 1. The bristle rod 21 is arranged in the collecting cover 12 and distributed along the length direction of the collecting cover 12. Two bristle rods 21 are arranged and are opposite to each other up and down, and the cloth passes through the two bristle rods 21.

[0037] Reference Figure 1 and Figure 2The suction mechanism 22 includes a suction box 221 and a suction fan 222. The suction box 221 is connected to the collection cover 12 through an air duct 223. The suction fan 222 is arranged on the inner side of the suction box 221. When the cloth is transported, the brush rod 21 brushes off impurities such as hair scraps on the cloth, and the impurities fall to the inner side of the collection cover 12. The suction fan 222 rotates and sucks impurities such as hair scraps in the collection cover 12 into the suction box 221 through the air duct 223 for collection, thereby reducing the amount of impurities on the cloth.

[0038] Reference Figure 3 The edge-pulling mechanism 3 includes an edge-pulling roller 31 and a mounting frame 32. A mounting plate 13 is arranged on the frame 1 at one side of the collecting cover 12. The mounting plate 13 is distributed along the width direction of the frame 1. A sliding groove 131 is opened on the mounting plate 13 along the length direction of the mounting plate 13. The mounting frame 32 is slidably installed in the sliding groove 131 of the mounting plate 13. A locking bolt 321 is arranged on the mounting frame 32. The edge-pulling roller 31 is rotatably installed on the mounting frame 32. The downward side of the edge-pulling roller 31 is tightly fitted against one side of the cloth. Two edge-pulling rollers 31 are arranged and are located at the upper and lower sides of the cloth. The side edges of the cloth are pressed by the upper and lower edge-pulling rollers 31, so that the side edges of the cloth are not easy to deviate. At the same time, the edge-pulling rollers 31 on both sides pull the cloth to reduce wrinkles on the cloth. When pulling the edges of cloths of different widths, the sliding mounting frame 32 drives the edge-pulling rollers 31 to move, and the mounting frame 32 is locked by the locking bolts 321 to adjust the position of the edge-pulling rollers 31 to be suitable for cloth operations of different widths.

[0039] Reference Figure 3 The edge-pulling roller 31 is provided with a thread 311. The threads 311 on the edge-pulling rollers 31 on both sides in the width direction of the cloth are wound in opposite directions. The edge-pulling rollers 31 on both sides pull the cloth. The threads 311 on the edge-pulling roller 31 increase the friction between the edge-pulling roller 31 and the cloth. At the same time, the threads 311 wound in opposite directions on both sides pull the two sides of the cloth to the opposite directions, which has a better wrinkle removal effect on the cloth.

[0040] Reference Figure 2 and Figure 3 There are two expanding rollers 4 and they are parallel to each other. The cloth is wound around the two expanding rollers 4 in sequence for expanding operation. The diameter of the cross section of the expanding rollers 4 gradually decreases from the middle to both ends. The cloth expands from the middle to both sides, and the wrinkles on the cloth are further reduced, so the wrinkle removal effect of the cloth is better.

[0041] Reference Figure 2 and Figure 4, mounting grooves 14 are vertically arranged at opposite sides of the frame 1, sliding blocks 15 are slidably installed at the mounting grooves 14 of the frame 1, both ends of the widening roller 4 are rotatably connected with the sliding blocks 15, and a spring 16 is arranged at the mounting grooves 14 of the frame 1, and one end of the spring 16 is connected with one side of the sliding block 15. When the cloth is widened and the widening roller 4 is tightened, the sliding blocks 15 at both ends of the widening roller 4 push the spring 16 to compress, and the widening roller 4 is elastically pressed to reduce the probability of damaging the cloth.

[0042] Reference Figure 3 The spray mechanism 5 includes a spray pipe 51 and a spray head 52. The spray pipe 51 is arranged on the frame 1 and is located at one side of the expansion roller 4. The spray pipe 51 is distributed along the width direction of the frame 1. The spray head 52 is arranged on the spray pipe 51. There are several spray heads 52 and they are arranged along the length direction of the spray pipe 51. The cloth is sprayed with the pretreatment liquid through the spray heads 52 on the spray pipe 51, and the pretreatment liquid is evenly distributed on the cloth.

[0043] The implementation principle of a pre-treatment device for fabric printing in an embodiment of the present application is as follows: after the fabric is brushed by the brush rod 21 on the inner side of the collecting cover 12, it is edged by the edge-drawing rollers 31 on both sides, the edge-drawn fabric is transported to two expanding rollers 4 for expansion, and the expanded fabric is transported to the spray pipe 51 for spraying the pre-treatment liquid.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
