Continuous dyeing machine

Abstract

This utility model discloses a continuous pad dyeing machine, including a dyeing tank containing dye solution. A dyeing roller is positioned below the dyeing tank, and two rollers arranged side-by-side are positioned above the tank. Fabric passes through the dyeing rollers and exits through the gap between the two rollers. A scraper is positioned on the side of the roller away from the gap, and a flexible scraper is positioned at the end of the scraper, abutting against the surface of the roller. A recovery tank is positioned below the scraper, and a filter screen is positioned at the bottom of the recovery tank. This utility model, by setting a scraper on the outside of the rollers, removes residual liquid and lint from the roller surface, ensuring the cleanliness of the side of the roller in contact with the fabric and guaranteeing the pad dyeing effect. The scraped liquid flows into the recovery tank, where the filter screen separates the lint, and the remaining liquid flows back into the dyeing tank.

Description

Technical Field

[0001] This utility model relates to the technical field of dyeing equipment, and in particular to the technical field of continuous dyeing machines. Background Technology

[0002] A continuous pad dyeing machine briefly immerses the fabric in dye liquor, then uses rollers to press the fabric, squeezing the dye liquor into the gaps in the fabric structure and removing excess dye liquor, so that the dye is evenly distributed on the fabric. Then, through processes such as steaming and baking, the dye and fiber are fully combined to achieve the dyeing purpose.

[0003] When using existing continuous dyeing machines, the liquid remaining on the surface of the rollers can affect the uniformity of the fabric's pick-up rate, resulting in different liquid absorption on both sides of the fabric and color differences between the left and right sides. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a continuous dyeing machine that can solve the above problems.

[0005] To achieve the above objectives, this utility model proposes a continuous dyeing machine, including an immersion tank containing a dye solution. An immersion roller is positioned below the immersion tank, and two rollers arranged side-by-side are positioned above the immersion tank. Fabric passes through the immersion rollers and exits through the gap between the two rollers. A scraper is positioned on the side of the roller away from the gap, and a flexible scraper is positioned at the end of the scraper, abutting against the surface of the roller. A recovery tank is positioned below the scraper, and a filter screen is positioned at the bottom of the recovery tank.

[0006] Preferably, the scraper plate has a guiding slope on the side near the flexible scraper, and the guiding slope is inclined toward the recycling tank.

[0007] Preferably, a spray pipe is provided above the scraper, the spray pipe is connected to a liquid inlet pipe, a liquid outlet pump is provided on the liquid inlet pipe, and a plurality of liquid outlet heads are provided on the side of the spray pipe facing the roller, the liquid outlet heads are inclined downward.

[0008] Preferably, the liquid outlet is a duckbill nozzle.

[0009] Preferably, the two scraper blades are arranged symmetrically in a figure-eight shape.

[0010] The beneficial effects of this utility model are as follows: By setting a scraper on the outside of the roller, the scraper removes residual liquid and lint from the roller surface, ensuring the cleanliness of the side of the roller that contacts the fabric and ensuring the dyeing effect; the scraped liquid flows into the recycling tank, the filter screen separates the lint, and the remaining liquid flows back into the dyeing tank; the spray pipe sprays and washes the roller surface to wash away the attached lint or impurities, avoiding any residue on the roller.

[0011] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a top view of the present invention; Figure 3 This is a schematic diagram of the scraper of this utility model.

[0013] In the diagram: 1. Dyeing tank; 2. Dyeing roller; 3. Roller; 4. Scraper; 5. Recovery tank; 6. Spray pipe; 7. Liquid inlet pipe; 8. Liquid outlet head; 41. Guide slope. Detailed Implementation

[0014] See Figure 1 , Figure 2 , Figure 3 A continuous dyeing machine includes an immersion tank 1 containing a dye solution. An immersion roller 2 is located below the immersion tank 1, and two rollers 3 arranged side by side are located above the immersion tank 1. After passing through the immersion rollers 2, the fabric exits through the gap between the two rollers 3. A scraper plate 4 is located on the side of the roller 3 away from the gap, and a flexible scraper is located at the end of the scraper plate 4. The flexible scraper abuts against the surface of the roller 3. A recovery tank 5 is located below the scraper plate 4, and a filter screen is located at the bottom of the recovery tank 5.

[0015] The scraper plate 4 is provided with a guide slope 41 on the side near the flexible scraper, and the guide slope 41 is inclined toward the recycling tank 5.

[0016] The two scraper blades are symmetrically arranged in a figure-eight shape.

[0017] To further enhance the cleaning effect, a spray pipe 6 is provided above the scraper 4. The spray pipe 6 is connected to a liquid inlet pipe 7. A liquid outlet pump is provided on the liquid inlet pipe 7. Several liquid outlet heads 8 are provided on the side of the spray pipe 6 facing the roller 3. The liquid outlet heads 8 are inclined downward.

[0018] The liquid outlet head 8 is a duckbill nozzle.

[0019] The inlet end of the inlet pipe 7 is set in the dyeing tank and equipped with a filter device. The outlet pump draws the filtered dye liquor into the spray pipe and sprays it onto the surface of the roller through the outlet head to rinse the roller. The rinsing liquid flows into the recovery tank along the scraper and flows back to the dyeing tank after filtration. The cleaning effect is good.

[0020] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
