Description

Technical Field

[0001] This utility model relates to the field of fabric oxygen bleaching technology, specifically an oxygen bleaching treatment device for preparing high flame retardant blended fabrics. Background Technology

[0002] Oxygen bleaching is a fabric bleaching method that uses oxygen-containing bleaching agents such as hydrogen peroxide as its core. It achieves whitening by decomposing stain pigments with active oxygen. It has the characteristics of minimal fiber damage and stable whiteness. Its bleaching agents include hydrogen peroxide, sodium percarbonate, sodium perborate, etc. It needs to be accelerated by high temperature of 80-100℃ in an alkaline environment (pH 10-11). Oxygen bleaching is usually used in the production and processing of fabrics.

[0003] In the oxygen bleaching process, the fabric is usually immersed in the oxygen bleaching agent. After immersion, the internal structure of the fabric is relatively compact, resulting in low absorption efficiency of the oxygen bleaching agent, which makes oxygen bleaching take a long time. Therefore, this does not meet the current requirements. To address this, we propose an oxygen bleaching treatment device for the preparation of high flame retardant blended fabrics. Utility Model Content

[0004] The purpose of this invention is to provide an oxygen bleaching treatment device for the preparation of high flame retardant blended fabrics, in order to solve the problems mentioned in the background art, such as the fact that in the process of oxygen bleaching fabrics, the fabric is mostly immersed in the oxygen bleaching agent, the internal structure of the fabric is relatively compact after immersion, the absorption efficiency of the oxygen bleaching agent is low, and thus the oxygen bleaching takes a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oxygen bleaching treatment device for preparing high flame-retardant blended fabrics, comprising an oxygen bleaching chamber, a support plate fixed to the top of the oxygen bleaching chamber, two drive motors fixed to the upper surface of the support plate, transmission pulleys fixed to the outer sides of the output shafts of the two drive motors, two fixed frames fixed to the inner side of the oxygen bleaching chamber, two supporting shafts rotatably mounted between the two fixed frames, a rotating roller fixed to the outer side of the supporting shafts, multiple rotating contact plates fixed to the outer side of the rotating rollers, a rotating pulley fixed to the outer side of one end of the supporting shafts, and a transmission belt sleeved on the outer side of the rotating pulley and the transmission pulley.

[0006] Preferably, four sets of fabric transfer rollers are installed inside the oxygen bleaching box, with two fabric transfer rollers in each set, and the four sets of fabric transfer rollers are symmetrically distributed in an inverted trapezoidal shape.

[0007] Preferably, the two are located on the upper inner side of the oxygen drift chamber, and the other two are located on the inner side of the oxygen drift chamber near the bottom and below the two fixing brackets.

[0008] Preferably, the rotating contact plate has a T-shaped structure, and the end face of the rotating contact plate away from the end of the rotating roller is an arc-shaped surface.

[0009] Preferably, the rotating contact plate has multiple ball grooves on the end face of the arc-shaped surface, and contact balls are rotatably engaged inside the ball grooves.

[0010] Preferably, the rotating contact plates are arranged in a spiral array around the axis of the rotating roller on the outside of the rotating roller, and the spacing between adjacent rotating contact plates is the same.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In the oxygen bleaching process, this invention utilizes a drive motor, transmission pulley, transmission belt, and rotating pulley to drive rotating rollers and rotating contact plates to rotate. This causes the rotating contact plates on the outer sides of the two rotating rollers to rotate towards each other. During the rotation, the fabric immersed in the oxygen bleaching agent is rubbed and pulled to both sides, allowing the fabric to unfold and fully contact the oxygen bleaching agent, thereby improving the absorption efficiency of the oxygen bleaching agent and enhancing the oxygen bleaching effect of the fabric.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, an oxygen bleaching treatment device for preparing high flame-retardant blended fabric includes an oxygen bleaching chamber 1. A support plate 3 is fixed to the top of the oxygen bleaching chamber 1. Two drive motors 4 are fixed to the upper surface of the support plate 3. Transmission pulleys 5 are fixed to the outer sides of the output shafts of the two drive motors 4. Two fixed frames 7 are fixed to the inner side of the oxygen bleaching chamber 1. Two support shafts 9 are rotatably installed between the two fixed frames 7. A rotating roller 8 is fixed to the outer side of the support shaft 9. Multiple rotating contact plates 11 are fixed to the outer side of the rotating roller 8. A rotating pulley 10 is fixed to the outer side of one end of the support shaft 9. A transmission belt 6 is sleeved on the outer side of the rotating pulley 10 and the transmission pulley 5. The drive motors 4, transmission pulleys 5, and transmission belt 6 drive the rotating pulley 10, support shafts 9, and rotating roller 8 to rotate, causing the rotating contact plates 11 on the outer side of the rotating roller 8 to rotate towards the middle of the two rotating rollers 8. During the rotation, the rotating contact plates 11 rub against the fabric and pull it to both sides of the fabric, thereby expanding the gaps in the internal structure of the fabric and accelerating the absorption of oxygen bleaching agent by the fabric.

[0020] Four sets of fabric transfer rollers 2 are installed inside the oxygen bleaching box 1. Each set of fabric transfer rollers 2 has two rollers. The four sets of fabric transfer rollers 2 are symmetrically distributed in an inverted trapezoidal shape. Two of them are located on the upper inside of the oxygen bleaching box 1, and the other two are located on the inner side of the oxygen bleaching box 1 near the bottom and below the two fixed frames 7. The fabric to be oxygen bleached is transferred by the four sets of fabric transfer rollers 2, ensuring that the fabric is completely immersed in the oxygen bleaching agent.

[0021] The rotating contact plate 11 has a T-shaped structure, and the end face of the rotating contact plate 11 away from the end of the rotating roller 8 is an arc-shaped surface. The rotating contact plates 11 are arranged in a spiral array around the axis of the rotating roller 8 on the outside of the rotating roller 8, and the spacing between adjacent rotating contact plates 11 is the same.

[0022] The rotating contact plate 11 has multiple ball grooves on its arc-shaped end face. Contact balls 12 are rotatably engaged inside the ball grooves. The contact balls 12 engaged at the ends of the arc-shaped surface can reduce the damage to the fabric during the rotation of the rotating contact plate 11, ensuring the unfolding of the internal structure of the fabric while avoiding damage to the fabric.

[0023] Working principle: When performing oxygen bleaching on fabric, the oxygen bleaching agent is first added into the oxygen bleaching chamber 1, ensuring that the oxygen bleaching agent submerges the rotating roller 8. The fabric is then passed between the four sets of fabric transfer rollers 2 and transported through them. During transport, the fabric is submerged in the oxygen bleaching agent and positioned below the rotating roller 8. At this point, the two drive motors 4 are energized and started. The drive motors 4 then drive the rotating pulley 10 to rotate via the transmission pulley 5 and transmission belt 6. The two rotating pulleys 10 then drive the supporting shaft 9 and the rotating roller 8 to rotate in opposite directions. This causes the rotating contact plates 11 on the outer sides of the two rotating rollers 8 to rotate between them. The rotating contact plates 11 contact the fabric from the middle, generating frictional force to both sides, thereby widening the internal structural gaps of the fabric and accelerating the absorption of the oxygen bleaching agent. This ensures sufficient contact between the oxygen bleaching agent and the fabric, thus shortening the oxygen bleaching time and improving the oxygen bleaching efficiency.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
