Description

Technical Field

[0001] The present invention relates to the technical field of textile heating, and specifically to an energy-saving heater structure with air inlet preheating. Background Art

[0002] Textiles are products processed by textile processing. They include yarns, woven fabrics, knitted fabrics, braided fabrics, etc. They are divided into two major categories: shuttle-woven fabrics and knitted fabrics. China is one of the earliest countries in the world to produce textiles, and the main production areas are Tongxiang, Zhejiang, Qinghe, Hebei, etc. Textile fabrics are divided into two categories according to the weaving method: weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics are often made of low-elastic polyester filaments, profiled polyester filaments, nylon filaments, cotton yarns, wool yarns, etc., and are woven on various weft knitting machines using flat stitch, modified flat stitch, rib flat stitch, double rib flat stitch, jacquard stitch, terry stitch, etc. The correct stacking method for textiles is to choose a place that is conducive to ventilation and fire prevention. All-cotton fabrics are best placed in a well-ventilated place, such as the place closest to the door and window. A door width of one meter is a conventional door width. 6 to 7 rolls are placed in a row. The second layer is placed horizontally longitudinally, and the quantity must be the same as the bottom layer. The third layer is still placed horizontally, with the same quantity, and so on. Before mass production of textiles, test production is required to test the overall performance of the textiles. There is a water washing step, and after water washing, heating and drying are required. Conventional heaters are not designed specifically for such application scenarios. Most of them do not have an air inlet preheating stage, resulting in sudden temperature differences when the water-washed textiles enter the heater for heating, causing damage to the textiles, being unable to effectively test the performance of the textiles themselves, being unable to adjust according to the size of the textiles, having a single and non-adjustable overall structure, and using manual operation for feeding and discharging, resulting in low overall efficiency. For this reason, we propose an energy-saving heater structure with air inlet preheating to solve the above problems. Summary of the Invention

[0042] Working principle:

[0043] During use, when the heating and drying are not started, the third motor 44 starts to drive the third gear 46 to rotate. The third gear 46 drives the third rack 43 to rise. The third rack 43 drives the sealing plate 42 to rise to open the entrance and exit 12. The fourth cylinder 62 pushes the adjusting assembly 5 and the heating assembly 6 to move slowly back and forth. The heating rod 638 stands vertically inside the outer cover 1 according to gravity. The heating rod 638 starts to heat at a low temperature. When the heating rod 638 moves, it preheats the inside of the outer cover 1 to maintain a low heat temperature inside the entire outer cover 1. The external fan performs air exchange and odor removal to maintain the ventilation inside the entire outer cover 1. When starting, the production equipment places the washed and cut fabric in the storage frame. The manipulator places the storage frame on the first rotating plate 26. The first motor 223 starts to drive the first gear 224 to rotate. The first gear 224 drives the first rack 222 to move. The first rack 222 drives the first moving frame 22 to move into the outer cover 1. After the first moving frame 22 reaches above the third moving frame 33, it stops. The second cylinder 25 starts to push the first push wheel 251 to rise and lift the first rotating plate 26, making the first rotating plate 26 tilt by 5°. The first cylinder 23 drives the lifting frame 24 and the first rotating plate 26 to descend. When one end of the storage frame touches the third moving frame 33, it stops. The second cylinder 25 drives the first push wheel 251 to descend, making the first rotating plate 26 slowly level. The storage frame slowly contacts the third moving frame 33, effectively preventing the fabric from wrinkling and warping.

[0044] When the stacking height of the storage frame is not high, the fourth cylinder 62 starts to push the adjustment component 5 and the heating component 6 to move to the center of the outer cover 1. The second motor 323 starts to drive the second gear 324 to rotate. The second gear 324 drives the second rack 322 to move. The second rack 322 drives the second moving frame 32 to move. The second moving frame 32 drives the third moving frame 33 to move below the heating component 6. The sealing plate 42 descends to close the entrance and exit 12. The fourth motor 532 starts to drive the first lead screw 531 to rotate. The first lead screw 531 drives the second push rod 54 to move. The second push runner 543 pushes the heating rod 638 to rotate. When the heating rod 638 is horizontal, it stops. The heating rod 638 starts to heat at a high temperature. When the heating rod 638 heats horizontally, the area is large, improving the heating effect. After heating is completed, the sealing plate 42 is opened. The third moving frame 33 and the lifting frame 24 move out of the outer cover 1 together. Then the first cylinder 23 starts to push the lifting frame 24 to rise. The first rotating plate 26 lifts the storage frame. The third moving frame 33 moves back into the outer cover 1. The manipulator takes away the storage frame;

[0045] When the stacking height of the storage frame is extremely high or when the stacking height of the storage frame meets the standard, the fourth cylinder 62 starts to push the adjustment component 5 and the heating component 6 to move to the center of the outer cover 1. The third cylinder 55 starts to push the push rod 551 forward. The push rod 551 drives the second push column 553 forward. The second push column 553 drives the first push column 521 forward through the push rod 551. The first push column 521 pushes the rotating rod 635 to rotate. The movable bracket 51 tilts and rises to push the rotating rod 635 to the horizontal position and then stops. The baffle 636 prevents the heating rod 638 from rotating in the reverse direction and provides support for the heating rod 638, making the heating rod 638 also in a horizontal state. The second motor 323 starts to drive the second gear 324 to rotate. The second gear 324 drives the second rack 322 to move. The second rack 322 drives the second moving frame 32 to move. The second moving frame 32 drives the third moving frame 33 to move below the heating component 6. The sealing plate 42 descends to close the entrance and exit 12. The heating rod 638 starts to heat at a high temperature. When the heating rod 638 heats horizontally, the area is large, improving the heating effect. After heating is completed, the sealing plate 42 is opened. The third moving frame 33 and the lifting frame 24 move out of the outer cover 1 together. Then the first cylinder 23 starts to push the lifting frame 24 to rise. The first rotating plate 26 lifts the storage frame. The third moving frame 33 moves back into the outer cover 1. The manipulator takes away the storage frame.
