Description

Technical Field

[0001] This application relates to the field of printing and dyeing equipment, and in particular to a dyeing machine with good extrusion dewatering effect. Background Technology

[0002] The development of short-process, low-water dyeing technology for polyester fabrics requires the use of dyeing machines. Dyeing machines are used to dye fabrics and have the characteristics of uniform dyeing and minimal damage to the dyed material.

[0003] Currently, Chinese utility model patent CN211471861U discloses an extrusion dewatering polyester dyeing machine, including a housing with an inlet and an outlet. An extrusion device and a filter device located below the extrusion device are located at the outlet. The filter device includes a support frame and a filter plate slidably connected to the support frame, and the filter plate is detachably connected to the housing. This utility model effectively reduces the re-entry of fabric impurities into the dye liquor.

[0004] The fabric may wrinkle during the conveying process. When the wrinkled fabric enters the extrusion device, creases will appear on the fabric, and the roll of fabric will be uneven, resulting in poor overall quality of the fabric roll. Utility Model Content

[0005] To reduce wrinkling of the fabric before it enters the extrusion device, this application provides a dyeing machine with good extrusion dewatering effect.

[0006] This application provides a dyeing machine with good extrusion dewatering effect, which adopts the following technical solution:

[0007] A dyeing machine with good extrusion dewatering effect includes a dyeing tank, an extrusion device, and a spreading device. The spreading device includes a spreading roller, a drive motor, several spreading components, and a drive component. The spreading roller is rotatably connected to the inner wall of the dyeing tank. The several spreading components are divided into two groups, which are distributed along the length of the spreading roller. Several spreading components in the same spreading group are distributed circumferentially along the spreading roller. Each spreading component includes a spreading belt, a matching wheel, and a driving wheel. The matching wheel and the driving wheel are distributed along the length of the spreading roller and are rotatably connected to the spreading roller. The spreading belt is sleeved on the matching wheel and the driving wheel. The drive component is used to drive the fabric in contact with the spreading belt to move away from the centerline of the spreading roller.

[0008] By adopting the above technical solution, the unfolding device is used to unfold the fabric entering the extrusion device, reducing the wrinkles of the fabric; during the conveying process, the fabric roll passes around the unfolding roller, the drive motor drives the unfolding roller to rotate, during the rotation the fabric will come into contact with the spreading belt, the drive component will drive the spreading belt to rotate, the spreading belt will drive the fabric to move away from the center line position of the unfolding roller, several spreading components are divided into two spreading groups, the two spreading groups are distributed along the length direction of the unfolding roller, the two spreading groups drive the fabric to move in opposite directions, the fabric is subjected to force at both ends along the width direction of the fabric, and the fabric unfolds flat.

[0009] Optionally, the driving component includes several worm gears, several worm shafts, several gears, and two gear rings. The worm gears correspond one-to-one with the driving wheel. The length of the worm shaft is parallel to the length direction of the unfolding roller. The worm shaft is rotatably connected to the unfolding roller and meshes with the worm gears. The gears correspond one-to-one with the worm shafts and are disposed on the worm shafts. The two gear rings correspond to the two ends of the unfolding roller respectively. The gear rings are disposed on the inner side wall of the dyeing tank and mesh with the gears.

[0010] By adopting the above technical solution, when the drive motor drives the unfolding roller to rotate, the unfolding roller rotates relative to the gear ring. The gear on the unfolding roller moves relative to the gear ring, the gear rotates, the gear drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the drive wheel to rotate, and the drive wheel and the mating wheel drive the expansion belt to rotate. The expansion belt will drive the fabric to move along the width direction of the fabric. The worm wheel and worm have a self-locking effect. When the drive motor does not drive the expansion component to rotate, the expansion belt will not move arbitrarily, and the wrinkle smoothing effect of the fabric is better. The unfolding roller can be driven to rotate and several expansion components can be moved by the drive motor alone, which is in line with the concept of green environmental protection.

[0011] Optionally, the spreading roller has a cavity inside and a flow hole for the dyeing liquid to flow through.

[0012] By adopting the above technical solution, since the fabric will retain dye liquor when it is taken out of the dyeing pool, when the fabric is flattened and is pressed by the unfolding roller, the dye liquor inside the fabric will flow out. Some of the dye liquor will carry lint. The flow hole can allow the lint to enter the cavity, reducing the secondary pollution of the dye in the dyeing pool by the lint.

[0013] Optionally, the unfolding roller has a placement groove for placing the radial expansion belt, the placement groove is connected to the cavity, the mating wheel is shuttle-shaped, the radial expansion belt is located in the placement groove, and the radial expansion belt is attached to the outer wall of the unfolding roller.

[0014] By adopting the above technical solution, the expansion belt, the mating wheel, and the driving wheel are all located in the placement groove, and the mating wheel is shuttle-shaped, so that the expansion belt can be flush with the outer wall of the unfolding roller, so that the unfolding roller remains cylindrical and the fabric can better fit the unfolding roller.

[0015] Optionally, the radial expansion band is provided with clearance holes for the dye to pass through.

[0016] By adopting the above technical solution, during the fabric unfolding process, the dye in the fabric will also enter the cavity inside the unfolding roller through the avoidance hole, and the lint in the dye will also enter the unfolding roller through the avoidance hole, reducing the secondary pollution of the dye bath by lint.

[0017] Optionally, the placement slot may be provided with a plurality of support bars for supporting the radial expansion strip.

[0018] By adopting the above technical solution, the support strip supports the expansion belt, allowing the expansion belt to better fit the outer wall of the unfolding roller. The support strip also reduces the deformation of the expansion belt and extends its service life.

[0019] Optionally, the extrusion device includes an extrusion roller, a moving roller, an extrusion cylinder, and an extrusion motor. The extrusion roller is rotatably connected to the side wall of the dyeing tank, and the moving roller is slidably connected to the side wall of the dyeing tank in a direction close to or away from the extrusion roller. The extrusion motor drives the extrusion roller to rotate, and the extrusion cylinder is used to drive the moving roller to move.

[0020] By adopting the above technical solution, when the fabric enters the extrusion device, the extrusion cylinder drives the moving roller to abut against the extrusion roller, the extrusion motor drives the extrusion roller to rotate, and the extrusion roller and the moving roller press against the fabric, and the dye in the fabric is squeezed out. The extrusion device has a simple structure and is easy to operate.

[0021] Optionally, both the extrusion roller and the moving roller are coated with a rubber layer.

[0022] By adopting the above technical solution, the rubber layer can better adhere to the fabric, increase the contact area between the extrusion roller, the moving roller and the fabric, and achieve a better extrusion effect for the fabric dye.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The unfolding device is used to unfold the fabric before the dye is extruded, thereby reducing wrinkles in the fabric;

[0025] 2. The flow holes inside the spreading roller and the clearance holes on the spreading belt are used to reduce the secondary entry of lint from the fabric into the dyeing bath;

[0026] 3. The extrusion device is used to compress the fabric to reduce the amount of dye remaining in the fabric. Attached Figure Description
