Description

Technical Field

[0001] The present invention relates to the technical field of slack dyeing and finishing, and particularly to a short-process slack dyeing and finishing process for pure cotton knitted fabrics. Background Art

[0002] Dyeing and finishing refers to the process mainly involving chemical treatment of textile materials (fibers, yarns, and fabrics), and is also commonly referred to as printing and dyeing in modern times. Together with spinning, weaving, or knitting production, dyeing and finishing form the entire process of textile production. Dyeing and finishing include pretreatment, dyeing, printing, and finishing;

[0003] In the prior art, after the fabric is dyed, it inevitably contains a large amount of moisture. Therefore, the dyed fabric needs to be centrifugally dehydrated before the shaping process. When dehydrating the fabric, centrifugation is mostly used for processing;

[0004] However, after the drum dehydrates the fabric for a long time, dye will adhere to the inside of the drum. Directly rinsing with clean water is very wasteful of water resources, and it is difficult to clean the inside of the drum thoroughly with clean water. Summary of the Invention

[0005] The purpose of the present invention is to provide a short-process slack dyeing and finishing process for pure cotton knitted fabrics to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A short-process slack dyeing and finishing process for pure cotton knitted fabrics, including:

[0007] Step 1: Dehydration. After the pure cotton knitted fabric is dyed and finished, it needs to be dehydrated. Place the pure cotton knitted fabric in the drum. The rotating component is connected to the connecting shaft, and the rotating component drives the drum to rotate to dehydrate the pure cotton knitted fabric;

[0008] Step 2: Pushing. Fill water into the water inlet, the water enters the first inner groove, and the water in the first inner groove enters the second inner groove through the through hole. Push the plug-in block through the air cylinder so that the plug-in block is inserted into the plug-in groove, and the extension ring rises. During the rising process of the extension ring, the water in the first inner groove and the second inner groove cleans the inner wall of the drum;

[0009] Step 3: Cleaning. During the rising process of the extension ring, the brush rises together with the extension ring, and the end of the brush abuts against the inner wall of the drum, so that the brush brushes the inside of the drum;

[0010] Step 4: Fixing. When the extension ring is at the bottom of the drum, screw the screw rod so that the fixing block moves, the fixing block is inserted into the through groove, and the teeth on the surface of the fixing block mesh with the card slots on the surface of the through groove to fix the position of the extension ring.

[0011] Preferably, through holes are formed on the surface of the drum. There are multiple groups of through holes, and the multiple groups of through holes are evenly distributed on the surface of the drum. A connecting shaft is arranged at the bottom of the drum, and the connecting shaft is connected to a rotating assembly. Through grooves are formed on the surface of the drum. There are two groups of through grooves, and the two groups of through grooves are symmetrically distributed on the surface of the drum.

[0012] Preferably, an extension ring is sleeved on the surface of the drum. An outer ring is arranged at the top of the extension ring. A plug-in groove is formed at the bottom of the extension ring. A water inlet is arranged at the top of the outer ring, and a water outlet is arranged at the bottom of the outer ring. A first inner groove is formed inside the outer ring.

[0013] Preferably, an inner plate is arranged inside the drum. A second inner groove is formed inside the inner plate. A brush is arranged in the second inner groove, and the end of the brush abuts against the inner wall of the drum. The outer ring and the inner plate are connected by a connecting plate.

[0014] Preferably, an extension plate is installed at the top of the outer ring. A screw rod is screwed in the extension plate. A fixing block is inserted at the end of the screw rod. The fixing block can rotate at the end of the screw rod and will not break away from the end of the screw rod. Tooth teeth are arranged on both sides of the surface of the fixing block.

[0015] Preferably, clamping grooves are formed on the bottom surface of the through groove. There are multiple groups of clamping grooves, and the multiple groups of clamping grooves are evenly distributed on the surface of the through groove.

[0016] Preferably, telescopic grooves are formed on the surface of the through groove. There are multiple groups of telescopic grooves, and the multiple groups of telescopic grooves are evenly distributed on the surface of the through groove. Telescopic blocks are inserted in the telescopic grooves.

[0017] Preferably, springs are arranged in the telescopic grooves. One end of each spring is connected to the inner wall of the telescopic groove, and the other end is connected to the end of the telescopic block. The end of the telescopic block is arc-shaped.

[0018] Preferably, a cylinder is arranged at the bottom of the drum. A plug-in block is arranged at the top of the cylinder. The plug-in block is arc-shaped. After the cylinder pushes the plug-in block to rise, the plug-in block is inserted into the plug-in groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] After the cotton knitted products proposed by the present invention are dyed and finished, dehydration is required. The cotton knitted products are placed in a drum. The rotating assembly is connected to a connecting shaft, and the rotating assembly drives the drum to rotate for dehydrating the cotton knitted products. Water is poured into the water inlet, and the water enters the first inner groove. The water in the first inner groove enters the second inner groove through the through hole. By pushing the plug block with a cylinder, the plug block is inserted into the insertion groove, and the extension ring rises. During the rising process of the extension ring, the water in the first inner groove and the second inner groove cleans the inner wall of the drum. During the rising process of the extension ring, the brush rises with the extension ring, and the end of the brush abuts against the inner wall of the drum, so that the brush brushes the inside of the drum. When the extension ring is located at the bottom of the drum, the screw is turned to move the fixing block. The fixing block is inserted into the through groove, and the teeth on the surface of the fixing block engage with the card slots on the surface of the through groove to fix the position of the extension ring. The inner wall of the drum is cleaned by the water in the first inner groove and the second inner groove, saving water resources and being able to clean the inner wall of the drum thoroughly.
