This system addresses the uneven treatment results and difficulty in precisely controlling treatment parameters of some traditional pretreatment methods mentioned in the background art, which results in suboptimal bonding between the fabric and the coating, impacting the quality and service life of the artificial leather. Furthermore, existing pretreatment systems suffer from low automation levels, a high level of manual labor, and low production efficiency.

[0016] The nozzle in the pretreatment liquid applying mechanism adopts an adjustable design, and the angle and spraying range of the nozzle can be adjusted according to the width of the base fabric and the treatment requirements to ensure that the pretreatment liquid evenly covers the surface of the base fabric.

[0017] The heating and drying device is arranged after the pretreatment liquid applying device, and is used to heat and dry the base cloth sprayed with the pretreatment liquid, and ensure that the base cloth is dried at an appropriate temperature to avoid affecting the pretreatment effect due to too high or too low temperature.

[0040] like Figure 1 As shown, a drying chamber 41 is provided in the mounting frame 1, and the drying chamber 41 also includes a top plate and four vertical plates fixed on the four sides of the top plate. Two of the opposite vertical plates of the drying chamber 41 are also provided with through holes for the base cloth to pass through.

[0042] The second electric telescopic rod 44 is set to change the distance between the blowing plate 43 and the base cloth, thereby adjusting the wind force blown by the blowing plate 43 to the base cloth, ensuring that the base cloth is dried at an appropriate temperature and avoiding the pretreatment effect being affected by too high or too low temperature.

[0043] Working principle:

[0044] When in use, the base fabric roll to be treated is placed on the winding roller 2 of the mounting frame 1, and the winding roller 2 drives the base fabric at a steady speed through the pre-treatment liquid applying mechanism and the heating and drying mechanism in sequence (the device is also externally connected to a mechanism for driving the cloth roll to move, driving the cloth roll to pass through the guide rod 3, the adjusting roller 4, the winding roller 2, the liquid adding chamber 23, the drying chamber 41 in sequence, and then move out of the mounting frame 1);

[0045] The specific working process in the liquid adding chamber 23 is as follows: the third motor 25 is started, and the output end of the third motor 25 drives the third transmission shaft 26 to rotate. The rotation of the third transmission shaft 26 drives the third movable block 27 to move vertically, thereby adjusting the height of the nozzle 40; the fourth motor 30 is started, and the output end of the fourth motor 30 drives the fourth transmission shaft 31 to rotate. The rotation of the fourth transmission shaft 31 drives the first gear 32 to rotate. The rotation of the first gear 32 causes the auxiliary block 29 to rotate around the inner ring 28, thereby adjusting the angle between the nozzle 40 and the base fabric; the fifth motor 33 is started, and the output end of the fifth motor 33 drives the fifth transmission shaft 34 to rotate. The rotation of the fifth transmission shaft 34 drives the second gear 35 to rotate. The rotation of the second gear 35 drives the third gear 37 meshing with it to rotate. The rotation of the third gear 37 drives the countershaft 36 and the fixed block 38 to rotate, thereby changing the direction of the nozzle 40. The above three operations are used in combination or adjusted separately, so that the nozzle 40 can better ensure that the pretreatment liquid evenly covers the surface of the base fabric.

[0046] The specific working process in the drying chamber 41 is as follows: start the second electric telescopic rod 44 to adjust the height of the blowing plate 43, and then the hot air flow passes through the air inlet pipe 42 and the blowing plate 43, and flows into the drying chamber 41 from the ventilation holes on the blowing plate 43.

[0047] During this period, the correction mechanism installed on the path of the base cloth can correct the position of the base cloth to ensure that the base cloth remains in a straight state during the operation. The specific operation is as follows: the first electric telescopic rod 5 is started, and the telescopic end of the first electric telescopic rod 5 drives the corresponding movable plate 7 to move, thereby limiting the end of the rolled cloth to adjust the position of the rolled cloth. At the same time, the telescopic rod 6 follows the corresponding first electric telescopic rod 5 to extend and retract, to cooperate with the operation of the first electric telescopic rod 5, and maintain the stability of the corresponding movable plate 7 during the movement;

[0048] When the tension is abnormal, the tension control mechanism installed on the path of the base cloth will make corresponding adjustments to the base cloth so that the base cloth always maintains appropriate tension to prevent wrinkles or stretching deformation of the base cloth during processing. The specific operations are as follows: start the second motor 18, and the output end of the second motor 18 drives the second transmission shaft 21 to rotate. The rotation of the second transmission shaft 21 drives the second bevel gear 22 to rotate. The rotation of the second bevel gear 22 drives the first bevel gear 20 to rotate. The rotation of the first bevel gear 20 drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the first moving block 13 to move vertically, thereby driving the adjusting roller 4 to adjust the height. At the same time, the second moving block 45 follows the movement of the adjusting roller 4 and moves vertically on the slide bar 15.
