Description

Technical Field

[0001] This invention relates to the field of hot air circulation devices, and specifically to a hot air circulation device for fabric feeding and baking processes. Background Technology

[0002] The hot air circulation device is used to dry fabrics to achieve the specified fabric moisture regain. Cotton greige fabrics and fabrics coming off water-jet looms tend to have high moisture regain, making them prone to mildew. They must be dried before storage or transportation. The fabric drying machine uses a steam-filled drying cylinder to dry the fabric, and the moisture regain of the greige fabric is controlled by increasing or decreasing the steam pressure.

[0003] Chinese invention patent CN108895781A, entitled "A Hot Air Circulating Drying Device," describes a device that uses a left-hand adjusting rod to move up and down, causing multiple sets of left-hand rotating rods to swing synchronously around multiple sets of left-front rotating shafts. This causes multiple sets of left-hand baffles to rotate synchronously in the same direction, allowing the opening between the left-hand baffles to be adjusted according to the rotation angle. Simultaneously, by moving left and right adjusting rods up and down, multiple sets of right-hand rotating rods can swing synchronously around multiple sets of right-front rotating shafts, causing multiple sets of right-hand baffles to rotate synchronously in the same direction. This allows the opening between the right-hand baffles to be adjusted according to the rotation angle, thus allowing air to enter the working chamber. The hot air drying airflow can be adjusted to different drying intensities according to the actual situation of the workpiece, reducing usage limitations. Multiple sets of workpieces can be placed on multiple racks, and multiple sets of left and right sliders slide within multiple grooves. Combined with the elasticity of multiple left and right support springs, multiple sets of workpieces can be clamped between multiple left and right clamping plates, improving the stability of the workpieces on the drying trays and enhancing its reliability. Furthermore, the two sets of left and two sets of right rollers at the bottom of the drying cart allow it to easily cross the height difference between the bottom inner wall of the loading / unloading port and the outside ground, facilitating entry into the working chamber and improving practicality.

[0004] The above-mentioned device has some shortcomings in use. It is not convenient to adjust the position of the air outlet, it is not convenient for the hot air in the hot air circulation box to flow evenly to bake the fabric, and it is inconvenient to adjust and use, which affects the drying efficiency of the device and the adjustment capability of the device. Therefore, a hot air circulation device for fabric baking processing that can solve the above problems is proposed. Summary of the Invention

The limiting rod 88 is inserted into the limiting hole 82 and is slidably installed through the inner wall of the storage groove 84 near the limiting groove 83. An operating plate 87 is fixedly installed on the side of the limiting rod 88 away from the limiting groove 83. A second spring 85 is fixedly installed on the side of the operating plate 87 away from the limiting rod 88. The second spring 85 serves to elastically reset the limiting rod 88. The end of the second spring 85 away from the operating plate 87 is fixedly installed on the inner wall of the storage groove 84. A guide rod 86 is slidably installed on the operating plate 87. The two ends of the guide rod 86 are fixedly installed on the inner wall of the storage groove 84. The guide rod 86 serves to guide and stabilize the operating plate 87. When using the device, first pull the operating plate 87, so that the operating plate 87 drives the limiting rod 88 to retract into the storage groove 84. At the same time, the limiting rod 88 is pulled out from the limiting groove 83. Simultaneously, the operating plate 87 slides on the guide rod 86 to compress the second spring 85, so that the second spring 85 is in a compressed state. Then, cover the cover plate 2, so that the cover plate 2 drives the limiting block 81 to be inserted into the limiting groove 83. Then, release the operating plate 87, so that the operating plate 87 drives the limiting rod 88 to be inserted into the limiting hole 82 under the elastic force of the second spring 85. This facilitates the limiting and fixing of the cover plate 2, making installation and disassembly convenient, which helps to improve the safety and stability of the device and improves the efficiency of device disassembly.

[0041] The working principle of this invention is as follows: When using the device, first pull the clamping plate 95, causing it to slide within the elastic groove 91. Simultaneously, the clamping plate 95 compresses the third spring 96, placing it in a compressed state. At the same time, the clamping plate 95 drives the slider 94 to slide within the slide groove 92, and the slider 94 slides on the slide rod 93. Then, the fabric is passed through the inlet and laid flat on the preheating plate 97. Next, the temperature controller 98 is activated to heat the preheating plate 97. Finally, the clamping plate is released. Holding plate 95, while simultaneously pressing the fabric onto preheating plate 97 under the elastic force of third spring 96, then the fabric passes through second winding rod 4 and first winding rod 3 in an inverted "S" shape, and is pulled out from the fabric outlet. Then, operating plate 87 is pulled, causing limiting rod 88 to retract into receiving groove 84, and simultaneously pulling limiting rod 88 out of limiting groove 83. At the same time, operating plate 87 slides on guide rod 86 to press second spring 85, so that second spring 85 is under pressure. In the retracted state, cover plate 2 is then closed, simultaneously causing cover plate 2 to drive the limiting block 81 into the limiting groove 83. Then, operating plate 87 is released, causing operating plate 87 to drive limiting rod 88 into limiting hole 82 under the elastic force of second spring 85, facilitating the limiting and fixing of cover plate 2. Then, electric telescopic rod 713 is activated, causing electric telescopic rod 713 to drive arc plate 714 to press rotating roller 711, while rotating roller 711 drives mounting plate 710 to press stabilizing rod 78 and first spring 79. Simultaneously, the stabilizing rod 78 slides on the cover plate 2, the first spring 79 is compressed, the rotating roller 711 squeezes and clamps the fabric, the motor 77 is started, and the output end of the motor 77 drives the reciprocating screw 72 to rotate. The reciprocating screw 72 drives the adjusting block 73 to slide in the adjusting groove 71. The adjusting block 73 slides on the balance rod 75, and the adjusting block 73 drives the air outlet rod 74 to move up and down in the hot air circulation box 1, so as to adjust the position of the air outlet rod 74.
