AI Technical Summary
In existing printing and dyeing technologies, the fabric may not be fully dyed in certain areas due to overlapping and surface impurities, which affects the dyeing effect.
Design a fabric turning roller assembly for printing and dyeing, including two rotating shafts and two turntables. The clamping rollers form a gap for the fabric to pass through. The clamping rollers are composed of fixed and sliding rollers. The sliding rollers slide in the groove to change the gap. The limiting component restricts the sliding range. The surface of the clamping rollers has ridges to increase friction, ensuring fabric turning and debris shaking off.
By turning the fabric over and shaking off debris, the dye is fully contacted with the fabric, improving the dyeing effect, reducing slippage, and extending the life of the roller assembly.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing and dyeing equipment, and more specifically, it relates to a printing and dyeing fabric turning roller assembly. Background Technology
[0002] Printing and dyeing is one of the common processing methods for fabrics. By using dyes, the color of the fabric is changed to create different visual effects to meet the needs of users. One method of printing and dyeing is to pre-treat the fabric and then immerse it in the dye solution. After the dye solution penetrates the interior of the fabric, the fabric is fixed to complete the dyeing process. However, when dyeing the fabric by soaking alone, the fabric may not be fully dyed in some areas due to overlapping or uncleaned impurities on the fabric surface. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing and dyeing fabric turning roller assembly.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing and dyeing fabric turning roller assembly, comprising two rotating shafts, two turntables between the two rotating shafts, and four clamping rods between the two turntables. The clamping rods are arranged in pairs, and a gap is formed between each pair of clamping rods for the fabric to pass through. The two pairs of clamping rods are symmetrically arranged on both sides of the turntable.
[0005] The present invention is further configured such that each set of clamping rollers consists of a fixed roller and a sliding roller, wherein the sliding roller is slidably connected to the turntable to change the size of the gap.
[0006] The present invention is further configured such that: a groove is provided on the turntable, the two ends of the sliding roller are slidably connected in the groove, and a limiting member is provided in the groove to restrict the sliding of the sliding roller.
[0007] The present invention is further configured such that: the limiting member is slidably connected to the end of the slide groove near the fixed roller, and when the fixed roller and the limiting member are respectively located at the two ends of the sliding roller, the limiting member abuts against the sliding roller.
[0008] The present invention is further configured such that: the number of grooves on any of the turntables is two, and the ends of the two sliding rollers are located in different grooves respectively.
[0009] The present invention is further configured such that: the surface of the clamping rod is formed with a plurality of protruding ridges, and the protruding ridges are arranged in a circumferential array on the surface of the clamping rod.
[0010] In summary, this utility model has the following beneficial effects: the fabric located between the clamping rollers is driven by the clamping rollers, forcing the fabric to turn over, avoiding fabric stacking, and at the same time, it can also shake off some residual debris, ensuring full contact between the fabric and the dye, improving the dyeing effect. When the sliding roller slides along the chute away from the fixed roller, the width of the gap increases, making it easier to guide the fabric through. Attached Figure Description

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0015] Example: A printing and dyeing fabric turning roller assembly, such as Figure 1 , Figure 2 As shown, the device includes two rotating shafts 1. The surface of each shaft 1 has a keyway for connection to a power source. Two turntables 2 are positioned between the two shafts 1, each turntable 2 connected to one of the two shafts 1. The turntables 2 and shafts 1 are connected by bolts. Four clamping rollers 3 are positioned between the two turntables 2, arranged in pairs. Each pair of clamping rollers 3 forms a gap for the fabric to pass through. The two pairs of clamping rollers 3 are symmetrically arranged on both sides of the turntables 2. During printing and dyeing, the fabric passes through these two gaps. An external power source drives the rotating shafts 1 to rotate back and forth, such as by rotating the motor in both directions, causing the turntables 2 to rotate. The clamping rollers 3 move in a bidirectional circular motion. At this time, the fabric located between the clamping rollers 3 is driven by the clamping rollers 3, which forces the fabric to turn over, avoids the fabric from piling up, and can also shake off some residual debris, ensuring that the fabric and dye are in full contact and improving the dyeing effect. The surface of the clamping rollers 3 is formed with several protruding ridges 8, which are arranged in a circular array on the surface of the clamping rollers 3. The protruding ridges 8 are integrally formed with the clamping rollers 3. In this embodiment, each clamping roller 3 has eight protruding ridges 8. The protruding ridges 8 increase the friction between the guide roller and the fabric and reduce slippage between the fabric and the guide roller.
[0016] like Figure 1 , Figure 2As shown, each set of clamping rollers 3 consists of a fixed roller 4 and a sliding roller 5. The fixed roller 4 is rotatably connected to the turntable 2, and the sliding roller 5 is slidably connected to the turntable 2 to change the gap size. The turntable 2 has a groove 6, and the two ends of the sliding roller 5 are slidably connected in the groove 6. The groove 6 is used to guide the sliding of the sliding roller 5. In a set of clamping rollers 3, when the sliding roller 5 slides along the groove 6 away from the fixed roller 4, the gap width increases, making it easier to guide the fabric through. The groove 6 is provided with a limiting member 7 to restrict the sliding of the sliding roller 5. The limiting member 7 is slidably connected to the end of the groove 6 near the fixed roller 4. When the fixed roller 4 and the limiting member 7 are respectively located in the groove 6, the gap width increases, making it easier to guide the fabric through. When the moving roller 5 is at both ends, the limiting member 7 abuts against the sliding roller 5. At this time, the limiting member 7 protrudes, which restricts the sliding range of the sliding roller 5 in the groove 6, thereby ensuring that the gap width is small, so that the fabric can rotate with the turntable 2. When the limiting member 7 retracts into the turntable 2, the groove 6 is unobstructed, and the sliding roller 5 can be slid to expand the gap. There are two grooves 6 on any turntable 2, and the ends of the two sliding rollers 5 are located in different grooves 6. The minimum distance between the two grooves 6 on the same turntable 2 is greater than the diameter of the sliding roller 5. The segmented grooves 6 avoid collisions between the two sliding rollers 5, ensuring the service life of the roller group as a whole.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
