[0016] Preferably, a tension roller is installed at the rear end of the inner cavity of the steaming box, and the tension roller is staggered in the upper and lower positions.

[0017] Preferably, a supporting base is provided at the lower end of the steaming box.

[0018] The color fixing method for a color fixing device for polyester fabric processing comprises the following steps:

[0019] Step 1: The polyester cloth enters the preheating and steaming stage: the preheated polyester cloth enters the steaming box, and the steaming device is turned on. Through the effects of high temperature and humidity, the dye molecules penetrate into the fibers of the polyester cloth and are fixed;

[0020] Step 2, processing of polyester cloth during steaming: During steaming, both sides of the polyester cloth pass over the guide wheel, the driving motor is turned on, and its output shaft drives the driving pulley to rotate on the one hand. Under the transmission of the first belt, the driven pulley equipped with the second sector gear rotates, and the outer gear ring of the second sector gear meshes with the tooth groove on one side of the inner side of the reciprocating lifting plate, and the lifting plate is driven to move toward the opening mechanism through the connecting arm. The positioning wheel in the lifting plate cooperates with the guide wheel to squeeze the two sides of the polyester cloth. As the lifting plate continues to descend, the friction between the positioning wheel, the guide wheel and the polyester cloth is further increased with the spring;

[0021] Step 3, realizing the formation of tension on both sides of the polyester cloth and steam penetration: on the other hand, the output shaft of the driving motor drives the driving shaft extending to the inside of the connecting plate to rotate, and the driving shaft is installed with a driving bevel gear at one end of the connecting plate, which drives the shaft on one side of the guide wheel to rotate under the meshing with the driven bevel gear, and cooperates with the second belt to form the synchronous rotation of the two guide wheels, and the opening mechanisms on both sides rotate in opposite directions, forming tension on both sides of the cloth, so that the spacing between the polyester filaments inside the cloth is increased, which is convenient for the rapid penetration of steam;

[0022] Step 4: Intermittent traction of fabric: When the output shaft of the driving motor rotates, it drives the first sector gear to rotate. The first sector gear drives the conveying tube to rotate to move the polyester fabric by meshing with the transmission gear. During the meshing of the first sector gear and the transmission gear, the second sector gear synchronously drives the reciprocating lifting plate to rise, so that the guide wheel and the positioning wheel are separated from both sides of the fabric to ensure smooth fabric transportation. Once the meshing ends, the polyester fabric stops in the steaming box. At this time, the second sector gear drives the reciprocating lifting plate to descend, and the guide wheel and the positioning wheel are in close contact with both sides of the fabric to form a pulling force, which effectively adjusts the spacing between polyester yarns inside the fabric.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention arranges an opening mechanism inside the steaming box, and the polyester cloth enters the preheating box from the cloth inlet, and enters the steaming box after being preheated. After the steaming device is turned on, the dye molecules penetrate into the fibers of the polyester cloth and are fixed by the action of high temperature and humidity. During the steaming process, both sides of the polyester cloth pass over the guide wheel, and the driving motor is turned on. On the one hand, its output shaft drives the active pulley to rotate, and drives the driven pulley equipped with the second sector gear to rotate under the transmission of the first belt. When the outer gear ring of the second sector gear meshes with the tooth groove on one side of the inner side of the reciprocating lifting plate, the lifting plate is driven to move toward the opening mechanism through the connecting arm, so that the positioning wheel in the lifting plate cooperates with the guide wheel to squeeze the two sides of the polyester cloth. As the lifting plate continues to descend, the spring further increases the positioning wheel, the guide wheel and the polyester cloth. The friction between the cloths, on the other hand, the output shaft drives the driving shaft extending to the inside of the connecting plate to rotate, and an active bevel gear is installed at one end of the connecting plate, which drives the shaft on one side of the guide wheel to rotate under the meshing with the driven bevel gear, and cooperates with the second belt to form the synchronous rotation of the two guide wheels, and the opening mechanisms on both sides rotate in opposite directions, forming tension on both sides of the cloth, so that the spacing between the polyester filaments inside the cloth is increased, which is convenient for the rapid penetration of steam, and realizes the efficient processing of polyester cloth from preheating to steaming. By utilizing the dual effects of the driving motor, tension is formed on both sides of the cloth, which effectively increases the spacing between the polyester filaments and accelerates the penetration efficiency of steam, thereby ensuring the color fixing effect while significantly improving the overall efficiency of cloth processing, and overcoming the problem that the color fixing effect and processing efficiency are difficult to achieve in the traditional steaming process.

[0025] 2. The present invention is provided with a cloth traction mechanism. When the output shaft of the driving motor rotates, it not only drives the first sector gear to rotate, but also drives the conveying pipe to rotate to move the polyester cloth through meshing with the transmission gear. Moreover, during the meshing of the first sector gear and the transmission gear, the second sector gear synchronously drives the reciprocating lifting plate to rise, so that the guide wheel and the positioning wheel are separated from both sides of the cloth, thereby ensuring smooth conveying of the cloth. Once the meshing is completed, the polyester cloth is stationary in the steaming box. At this time, the second sector gear drives the reciprocating lifting plate to descend, and the guide wheel and the positioning wheel are in close contact with both sides of the cloth to form a pulling force, effectively adjusting the spacing between polyester filaments inside the cloth and promoting rapid steam penetration. This design not only ensures the continuous and stable conveying of the cloth, but also optimizes the steaming and color fixing effect.

[0026] 3. The present invention installs a preheating tube between the preheating box and the cooling box. When the color-fixed polyester cloth is moved out of the steaming box, its own temperature is relatively high. By turning on the air pump, external air is replenished from the outlet end of the cooling box. When the normal temperature air contacts the polyester cloth, heat exchange can be formed with it. On the one hand, the temperature of the polyester cloth is reduced, and on the other hand, the temperature of the air is increased. Under the negative pressure of the air pump, the heated air is transported to the preheating box to preheat the cloth moving inside. This not only improves the energy utilization efficiency, but also ensures the temperature control of the polyester cloth during the cooling and preheating process, further improving the color fixing effect and the overall processing efficiency.

10. The color fixing method for the color fixing device for polyester fabric processing according to claim 9, characterized in that: The steps include: Step 1: The polyester cloth enters the preheating and steaming stage: the preheated polyester cloth enters the steaming box (1), and the steaming device (21) is turned on. Through the effects of high temperature and humidity, the dye molecules penetrate into the fibers of the polyester cloth and are fixed; Step 2, processing of the polyester cloth during the steaming process: During the steaming process, both sides of the polyester cloth pass over the guide wheel (10), the drive motor (8) is turned on, and its output shaft drives the driving pulley (24) to rotate. Under the transmission of the first belt (26), the driven pulley (25) equipped with the second sector gear (30) rotates, and the outer tooth ring of the second sector gear (30) meshes with the tooth groove (29) on one side of the inner side of the reciprocating lifting plate (22), and the lifting plate (11) is driven to move toward the opening mechanism (9) through the connecting arm (14). The positioning wheel (36) in the lifting plate (11) cooperates with the guide wheel (10) to squeeze the two sides of the polyester cloth. As the lifting plate (11) continues to descend, the friction between the positioning wheel (36), the guide wheel (10) and the polyester cloth is further increased by the spring (37); Step 3, achieving the formation of tension on both sides of the polyester cloth and steam penetration: the output shaft of the driving motor (8) drives the driving shaft (23) extending to the inside of the connecting plate (31) to rotate, and the driving shaft (23) is installed with a driving bevel gear (32) at one end located inside the connecting plate (31). Under the meshing with the driven bevel gear (33), the shaft on one side of the guide wheel (10) is driven to rotate, and the second belt (34) is cooperated to form the two guide wheels (10) to rotate synchronously, and the opening mechanisms (9) on both sides rotate in opposite directions, so that tension is formed on both sides of the cloth, so that the spacing between the polyester filaments inside the cloth is increased, which is convenient for the rapid penetration of steam; Step 4, intermittent traction of the fabric: When the output shaft of the driving motor (8) rotates, the first sector gear (27) is driven to rotate. The first sector gear (27) drives the conveying tube (18) to rotate to move the polyester fabric by meshing with the transmission gear (28). During the meshing of the first sector gear (27) and the transmission gear (28), the second sector gear (30) synchronously drives the reciprocating lifting plate (22) to rise, so that the guide wheel (10) and the positioning wheel (36) are separated from both sides of the fabric to ensure smooth fabric transportation. Once the meshing is completed, the polyester fabric is stationary in the steaming box (1). At this time, the second sector gear (30) drives the reciprocating lifting plate (22) to descend, and the guide wheel (10) and the positioning wheel (36) are in close contact with both sides of the fabric to form a pulling force, which effectively adjusts the spacing between polyester yarns inside the fabric.
