Description

Technical Field

[0001] The utility model relates to the technical field of cloth printing and dyeing, in particular to a dyeing vat for cloth printing and dyeing. Background Art

[0002] The dye vats commonly used for fabric printing and dyeing can be made of stainless steel, ceramic or plastic. These materials are resistant to corrosion, high temperatures and chemicals, making them suitable for use in environments with dyes and chemicals. Dye vats are usually designed as stainless steel cylinders or squares with appropriate capacity to accommodate the required amount of fabric. During the dyeing process, the fabric is immersed in the dye vat and comes into contact with the dye and other chemicals to achieve the desired dyeing effect.

[0003] When using the existing dyeing vat for printing and dyeing fabrics, the fabric to be printed and dyed is usually placed in the dyeing vat as a whole, and the hydraulic cylinder is used to continuously expand and contract to squeeze and release the fabric, so that the dye is fully immersed in the fabric, and the fabric is taken out as a whole after a period of time. However, in actual printing and dyeing operations, it is found that since the dye contains multiple components, when the fabric is pressed down as a whole, not only is it easy to form wrinkles on the fabric, but the solid components in the dye are gathered under the fabric, and most of the solid components in the dye are attached to the lower side of the fabric, resulting in a large color difference in the fabric after printing and dyeing. For this reason, we propose a dyeing vat for printing and dyeing fabrics. Utility Model Content

[0027] The vertical groove is used to limit the adjustment direction of the cloth extrusion assembly. In addition, the driving assembly serves as a power input to control the rolling roller 6 in the cloth extrusion assembly to maintain a horizontal state and move up and down;

[0028] A dye spraying assembly is installed between the inner walls of the dyeing cylinder 1 and is located above the upper transmission roller 3 at the middle position;

[0029] A dye stirring assembly, which is installed at the outer end of the printing and dyeing cylinder 1 and extends into the interior of the printing and dyeing cylinder 1;

[0030] Under the joint action of the dye spraying component and the dye stirring component, the dye used for printing and dyeing in the printing and dyeing cylinder 1 can be continuously stirred and extracted, so that the dye is prevented from precipitating during the circulation process, thereby ensuring the uniformity of the cloth during printing and dyeing;

[0031] Both ends of the inner wall of the dyeing cylinder 1 are fixed with symmetrically arranged fixing bars 18 with an L-shaped cross section, and a lead-out roller 19 is rotatably arranged between the side walls of the fixing bars 18;

[0032] Under the action of the lead-out roller 19, the moving direction of the cloth located at the two ends of the inner side of the printing and dyeing cylinder 1 is conveniently changed, and the cloth is led out from the inner side of the printing and dyeing cylinder 1 to be rolled up or other operations are performed on it.

[0033] Furthermore, the cloth extrusion assembly includes a synchronous screw 4 rotatably arranged in the vertical groove, and the top of the synchronous screw 4 is fixedly connected to a transmission rod 7 extending to the top of the printing and dyeing cylinder 1, and the outer circumference of the synchronous screw 4 is rotatably connected to a sliding block 5 that can slide up and down in accordance with the vertical groove, and a rolling roller 6 is rotatably arranged between the side walls of the sliding block 5, and the spacing between the rolling roller 6 and the upper transmission roller 3 can be changed after moving up and down under the action of the synchronous screw 4 and the sliding block 5.

[0034] The external threads of the synchronous screws 4 on both sides of the same cloth extrusion assembly rotate in opposite directions, so that when the driving assembly simultaneously controls the synchronous screws 4 in the cloth extrusion assembly to rotate, the sliding block 5 keeps the same moving direction and moves simultaneously, so as to control the rolling roller 6 to move up and down in a horizontal state.

[0035] Furthermore, the driving assembly includes a transmission frame 14 fixed between the tops of the printing and dyeing cylinders 1, a synchronous motor 13 is fitted and installed on the surface of the transmission frame 14, a fourth bevel gear 12 is sleeved on the end of the output shaft of the synchronous motor 13, a synchronous rod 10 is rotatably arranged inside the transmission frame 14 through a bearing seat, a third bevel gear 11 is sleeved on the outer periphery of the middle part of the synchronous rod 10 and is transmission-connected to the fourth bevel gear 12, and second bevel gears 9 are sleeved on both ends of the synchronous rod 10, the second bevel gear 9 is meshed and transmitted with a first bevel gear 8 sleeved on the outer periphery of the cloth extrusion assembly, and the first bevel gear 8 is sleeved and fixed on the end of the transmission rod 7.

Therefore, combined with the opposite rotation directions of the external threads of the synchronous screws 4 on both sides in the same cloth extrusion assembly, the rolling roller 6 can be controlled to move horizontally up and down, and the distance between the rolling roller 6 and the upper transmission roller 3 thereunder can be changed. As a result, when the cloth passes through the upper transmission roller 3 and the rolling roller 6, it can be squeezed by the rolling roller 6 and the upper transmission roller 3 to squeeze out the dye pre-immersed in the cloth, and then the dye is repeatedly immersed in the cloth, and the printing and dyeing effect is ensured by multiple immersion of the dye.

The wheel 11 controls the rotation of the synchronous rod 10, and the synchronous rod 10 then controls the rotation of the transmission rod 7 through the meshing transmission of the second bevel gear 9 at both ends and the first bevel gear 8. The transmission rod 7 drives the corresponding synchronous screw 4 to rotate, causing the sliding block 5 to move simultaneously when the synchronous screw 4 rotates, thereby driving the rolling roller 6 to move downward, and the cloth passing through the upper transmission roller 3 is squeezed between the rolling roller 6 and the upper transmission roller 3. At the same time, the output shaft of the stirring motor 21 drives the pulley 22, the disc 23 and the stirring rod 24 to rotate through the gear belt, so as to stir and mix the dye in the printing and dyeing cylinder 1 to prevent the dye from precipitating.
