Description

Technical Field

[0001] This utility model relates to the field of fabric dyeing technology, and in particular to a preheating high-temperature dyeing machine. Background Technology

[0002] In the textile printing and dyeing industry, high-temperature dyeing is a common process used to evenly penetrate dye into the fiber to achieve the desired color effect.

[0003] However, in actual production, fabrics often face the problem of sudden temperature changes when entering a high-temperature dyeing machine. Because the dye liquor temperature inside the dyeing machine is high (usually above 100°C), while the initial temperature of the fabric is usually close to the ambient temperature (about 20-30°C), there is a significant temperature difference between the two. This temperature difference causes the fabric fibers to undergo drastic thermal stress changes in a short period of time, which may lead to damage to the fiber structure, such as reduced fiber strength, loss of elasticity, or surface roughness. In addition, sudden temperature changes can also affect the adsorption and diffusion rate of dyes, resulting in uneven dyeing and quality problems such as color difference, color spots, or dyeing defects.

[0004] These problems not only reduce the product qualification rate, but also increase production costs and waste resources. Therefore, how to effectively reduce the temperature difference when the fabric enters the high-temperature dyeing machine has become a technical problem that the textile printing and dyeing industry urgently needs to solve. To this end, we propose a preheating high-temperature dyeing machine. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides, for example Figures 1-5The preheating high-temperature dyeing machine shown includes a dyeing machine body 101, a fabric feeding mechanism, a hot air mechanism, a connecting mechanism, and a limiting mechanism. A feed trough 102 is provided on one side of the dyeing machine body 101. The fabric feeding mechanism is located on one side of the dyeing machine body 101 and guides the fabric into the dyeing machine body 101. The hot air mechanism is located between the fabric feeding mechanism and the dyeing machine body 101 and provides hot air into the fabric feeding mechanism. The connecting mechanism is located on the outer wall of the fabric feeding mechanism and blows the hot air from the fabric feeding mechanism onto the fabric. The limiting mechanism is located on the outer wall of the fabric feeding mechanism, allowing the fabric to enter the dyeing machine body 101 close to the fabric feeding mechanism. Then, through the cooperation of the hot air mechanism and the connecting mechanism, hot air is blown onto the fabric close to the fabric feeding mechanism, thereby preheating the fabric. This reduces the temperature difference between the fabric and the high-temperature dye liquor, avoiding fiber damage and uneven dyeing caused by sudden temperature changes, thus improving the dyeing effect of the fabric.

[0038] The fabric feeding mechanism includes a fixed cylinder 201 and a fixed plate 202. The fixed cylinder 201 is located on one side of the dyeing machine body 101, and the fixed plate 202 is symmetrically fixedly connected to the end of the fixed cylinder 201. One side of the fixed plate 202 is fixedly connected to the outer wall of the dyeing machine body 101. Guided by the fixed cylinder 201, the fabric passes through the feeding trough 102 and enters the dyeing machine body 101 through the fabric feeding mechanism.

[0039] The hot air mechanism includes a hot air blower 301 and a connecting pipe 302. The hot air blower 301 is installed on the outer wall of the dyeing machine body 101. One end of the connecting pipe 302 is connected to the output end of the hot air blower 301, and the other end of the connecting pipe 302 is fixedly inserted and connected to the front of the fixed cylinder 201. The hot air generated by the hot air blower 301 is blown into the fixed cylinder 201 through the connection of the connecting pipe 302. The hot air blower 301 is electrically connected to an external power supply through an external switch, which facilitates the operator to control the hot air blower 301 and improves the safety and convenience of the operation of the hot air blower 301.

[0040] The connecting mechanism includes a rotating pipe 401 and a connecting groove 403. The rotating pipe 401 is rotatably sleeved on the outer wall of the fixed cylinder 201. The outer wall of the rotating pipe 401 is provided with connecting holes 402. The connecting groove 403 is opened on the outer wall of the fixed cylinder 201. When the fabric passes through the fabric conveying mechanism, the fabric is in contact with the rotating pipe 401. With the cooperation of the limiting mechanism, the part of the fabric in contact with the rotating pipe 401 is opposite to the position of the connecting groove 403. At this time, the fabric passes around the outer wall of the rotating pipe 401, so that the hot air in the fixed cylinder 201 can be blown out to the fabric through the connecting groove 403 and the corresponding connecting holes 402, thereby preheating the fabric.

[0041] The outer wall of the fixed cylinder 201 has multiple ball holes 501 arranged in a ring array. A ball 502 is movably held on the outer wall of the ball hole 501. The inner wall of the rotating tube 401 has an annular groove. The outer wall of the ball 502 fits against the inner wall of the annular groove. By rotating the ball 502 in the ball hole 501 and limiting the ball 502 by the annular groove, the rotating tube 401 can rotate stably on the outer wall of the fixed cylinder 201, ensuring the stability of the communication mechanism.

[0042] The limiting mechanism includes a limiting roller 601, a fixed frame 602, a slider 603, and a spring 604. The outer wall of the limiting roller 601 is fitted against the outer wall of the rotating tube 401. The fixed frame 602 is fixedly connected to the outer wall of the fixed cylinder 201. The outer wall of the slider 603 is slidably connected to the inner wall of the fixed frame 602. The limiting roller 601 is rotatably connected between the two sliders 603. The spring 604 is located between the slider 603 and the inner wall of the fixed frame 602. The fabric first passes through the space between the limiting roller 601 on one side and the rotating tube 401, and then passes through the space between the rotating tube 401 and the limiting roller 601 at the top. Then the fabric enters the feed trough 102. This allows the fabric to fit against the outer wall of the rotating tube 401 between the two limiting rollers 601 during movement. This part also corresponds to the connecting groove 403, thus ensuring that hot air can be stably blown onto the fabric and ensuring the stability of the fabric preheating process.

[0043] The inner wall of the fixed frame 602 is fixedly connected to a limiting rod 701, and a spring 604 is sleeved on the outer wall of the limiting rod 701. The outer wall of the slider 603 is provided with a limiting hole 702. The outer wall of the limiting rod 701 and the inner wall of the limiting hole 702 are movably interlocked. Through the mutual limiting of the limiting rod 701 and the limiting hole 702, the slider 603 moves stably within the fixed frame 602, ensuring the stability of the limiting mechanism.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
