[0011] The present application also provides a control method for a high-efficiency heating oven for automobile carpets, wherein a plurality of temperature detection devices are further provided in the heating box, and the temperature detection devices are used to detect the temperatures at different positions in the heating box. The control method comprises the following steps: S1, the heating box detects whether a staff member inputs a material loading request, and if so, the telescopic cylinder at the top of the door panel is retracted, and the door panel rises and opens under the action of the traction member, otherwise, the detection continues; S2. The staff assembles the transfer frame and the opening of the heating box so that the fabric support of the material layer matches the position of the loading support in the heating plate, so that the fabric in the material layer can be pushed into the heating box; S3. The staff pushes the fabrics in the material layer onto the heating plate in the heating box, and at the same time, the telescopic cylinder on the top of the door panel pushes the door panel to control its closing; S4, setting the working temperature in the heating box to W, and starting the heating plate in the heating box to heat up, and turning on the fan and shutter in the temperature control device to disturb the heating box, and setting the working time of the heating plate and the temperature control device to T.

Conversely, if 0.5W<X<1.5W, it is determined that the current heating temperature is normal and the device continues to operate for T2 time. S7. After the T2 time period, the telescopic cylinder opens the door panel to dissipate heat inside the box. The heat dissipation time is T3. After the T3 time period, the staff pulls the fabric in the heating plate along the feeding bracket and the fabric bracket back to the transfer frame to complete the heating of the carpet.

[0012] By adopting the above technical scheme, the beneficial effects are as follows: 1. By providing a heating box in the device, and the heating box is provided with several layers of heat insulation layers, the heating and forming of multiple pieces of fabrics can be achieved at the same time, and the heat insulation layer is provided with a heating plate, and the fabric is placed on the heating plate and heated. At the same time, during the heating process, a temperature control device is provided on both sides of the box, and the temperature control device includes a fan and a shutter, so that during the heating production of the fabric, the fan and the shutter cooperate to form an irregular turbulence on the inside of the heating box, so that the hotter air flow in the heating box near the heating plate area is blown to other positions in the heating box, so that the temperature in the heating box remains basically consistent, and the speed of temperature increase in the heating box is also accelerated. In addition, door panels are provided on both sides of the heating box, and the inner side of the door panel and the surface of the heating plate are provided with a structure for heat preservation, so that the temperature inside the heating box decreases slowly after heating, and the heat preservation effect is good. At the same time, the hot air in the heating box can be discharged through the exhaust valve, the overall use effect is good, and the processing cost is low.

[0013] 2. Furthermore, the temperature control device includes a plurality of fans arranged on the left and right sides of the heating box, shutters arranged on the fans, and exhaust valves arranged on the shutters and on the top of the heating box, the exhaust valve is connected to the ventilation duct, and in the process of heating and temperature rising control of the heating box, the shutters in the heating box are swung irregularly by the guide motor, so that the wind blown into the heating box by the fan is irregularly turbulent in the heating box, so that the temperature inside the heating box rises quickly, and at the same time, the temperature at various places inside the heating box is evenly set, reducing the temperature difference at different positions, so that the fabric in the heating box is heated evenly during the heating process, the qualified rate of the finished product is high, and the processing effect is good.

[0014] 3. At the same time, in order to facilitate the transportation of fabrics and the loading of fabrics on the heating plate, the loading mechanism includes loading brackets arranged at both ends of the heating plate and a transfer frame arranged at the opening, the transfer frame is provided with a plurality of material storage layers, the fabrics are placed on the material storage layers and can slide on the material storage layers, fabric brackets are also provided on both sides of the material storage layers, the positions of the fabric brackets match the positions of the loading brackets, the fabric brackets are provided with a fabric frame for placing fabrics, the fabric frame is arranged on the fabric bracket and can be pushed into the heating box along the fabric bracket, the overall processing is convenient, and at the same time, no manual handling is required during the loading process, the staff only needs to push or pull the fabric frame directly into or out of the oven through a three-foot hook, the distance between the staff and the heating box is far, which effectively prevents the staff from being injured by high temperature, and at the same time, universal wheels are provided at the bottom of the transfer frame, so that the transfer frame can move quickly on the ground, thereby speeding up production efficiency.

[0015] 4. Furthermore, in the process of heating the fabric in the above-mentioned oven, in order to improve the processing accuracy and prevent temperature changes from affecting the qualified rate of the product, in the process of processing the fabric in the heating box, a temperature detection device is set at multiple positions of the heating box, and the temperature detection device is used to detect the temperature of each position in the heating box, so that the specific temperature at each position in the box can be easily detected to prevent the uneven heating of the fabric due to different temperatures in the box from affecting the qualified rate of the finished product. Specifically, by setting the heating temperature of the fabric to W, in the process of heating the inside of the heating box, the air temperature near the heating plate in the heating box rises faster, and the temperature of the rest of the parts rises slower. The longer the heating time, the greater the temperature difference in the heating box. The fan and the shutter make the fans on both sides blow against each other, so that irregular turbulence is formed in the oven, and the air with higher temperature in the heating box exchanges heat with the air with lower temperature in the heating box, so that the temperature difference between various parts in the deheating box is smaller, and at the same time, the overall temperature rise in the heating box can be accelerated, thereby improving The efficiency of production is improved. Furthermore, in order to prevent the temperature in the heating box from being too high, thereby affecting the effect of the finished product, after the heating box is heated, in order to prevent the temperature in the heating box from being too high or too low, thereby affecting the qualified rate of the product, the temperatures detected by each temperature detection device are averaged. If the measured average value is greater than 1.5W, it is judged that the current temperature in the heating box is too high. At this time, it is necessary to dissipate heat inside the heating box. The door panels on both sides of the heating box are opened so that the hotter air inside the heating box is exchanged with the colder air outside the heating box, so that the temperature inside the heating box can drop quickly to prevent the fabric from being burned. At the same time, in the process of cooling the inside of the heating box, the temperature detection device can further detect the average temperature in the heating box. If the average temperature in the heating box is less than 0.5W, it is judged that the current temperature inside the heating box is too low, and the door panels on both sides of the heating box are closed and continue to heat. The above scheme can effectively avoid temperature changes in the heating box, thereby improving the qualified rate of processed products and processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] At the same time, in order to facilitate the transportation of fabrics and the loading of fabrics on the heating plate 7, the loading mechanism 10 includes loading brackets 101 arranged at both ends of the heating plate 7 and a transfer frame 102 arranged at the opening 4, and the transfer frame 102 is provided with a plurality of material storage layers 103, and the fabrics are placed on the material storage layers 103 and can slide on the material storage layers 103.

If the temperatures of W1, W2, W3, and W4 are similar, it is determined that the temperature difference in the heating box 2 is small, and the average value of the current temperature in the heating box 2 is recorded as X. Otherwise, it is determined that the temperature distribution in the heating box 2 is uneven, and the heating box 2 continues to be heated. S6. Compare X and W. If X≤0.5W, it is determined that the current temperature in the heating box 2 is too low to meet the heating demand of the car carpet. The heating plate 7 and the control device continue to work for T1 time and then detect again. If X≥1.5W, it is determined that the current temperature in the heating box 2 is too high.

Specifically, by setting the heating temperature of the fabric to W, in the process of heating the inside of the heating box 2, the air temperature near the heating plate 7 in the heating box 2 rises faster, and the temperature of the rest of the parts rises slower. The longer the heating time, the greater the temperature difference in the heating box 2. The fan 91 and the shutter 92 make the fans 91 on both sides blow against each other, so that irregular turbulence is formed in the oven, and the air with higher temperature in the heating box 2 exchanges heat with the air with lower temperature in the heating box 2, so that the temperature difference between various parts in the deheating box is smaller, and at the same time, the overall temperature rise in the heating box 2 can be accelerated, thereby improving the production efficiency. Furthermore, in order to prevent the temperature in the heating box 2 from being too high, thereby affecting the effect of the finished product, after the heating box 2 is heated, in order to prevent the temperature in the heating box 2 from being too high or too low, thereby affecting the qualified rate of the product, the temperatures detected by each temperature detection device are averaged. If the measured average value is greater than 1.5W, it is determined that the current temperature in the heating box 2 is too high. At this time, the heat inside the heating box 2 needs to be dissipated. The door panels 5 on both sides of the heating box 2 are opened, so that the hotter air inside the heating box 2 is separated from the heating box 2. The cooler air from the outside is exchanged, so that the temperature inside the heating box 2 can drop quickly to prevent the fabric from being burned. At the same time, in the process of cooling the inside of the heating box 2, the temperature detection device can further detect the average temperature inside the heating box 2. If the average temperature inside the heating box 2 is less than 0.5W, it is judged that the current temperature inside the heating box 2 is too low, and the door panels 5 on both sides of the heating box 2 are closed and heating continues. The above scheme can effectively avoid temperature changes in the heating box 2, thereby improving the qualified rate of finished products and the processing efficiency.

One end of the steel wire rope (53) is connected to the door panel (5), and the other end is provided with a traction member (54). The traction member (54) is used to tighten the steel wire and cooperate with the telescopic cylinder (6) to complete the opening and closing of the door panel (5).

7. The high-efficiency heating oven for automobile carpet fabric according to claim 1, characterized in that: The portion of the door panel (5) disposed on the inner side of the heating box (2) is also provided with a heat-insulating coating, the surface of the heating plate (7) is provided with a heat-insulating layer (3), and a fixed sheet metal is provided outside the heat-insulating layer (3).

8. A control method for a high-efficiency heating oven for automotive carpet fabrics applicable to any one of claims 1 to 7, characterized in that: The heating box (2) is also provided with a plurality of temperature detection devices, and the temperature detection devices are used to detect the temperature at different positions in the heating box (2). The control method comprises the following steps: S1, the heating box (2) detects whether the staff inputs a material loading request, and if so, the telescopic cylinder (6) at the top of the door panel (5) is retracted, and the door panel (5) is lifted up and opened under the action of the traction member (54); otherwise, the detection is continued; S2. The staff assembles the transfer frame (102) and the opening (4) of the heating box (2) so that the fabric support (104) of the material storage layer (103) matches the position of the material loading support (101) in the heating plate (7), so that the fabric in the material storage layer (103) can be pushed into the heating box (2); S3, the staff pushes the fabric in the material layer (103) onto the heating plate (7) in the heating box (2), and at the same time the telescopic cylinder (6) on the top of the door panel (5) pushes the door panel (5) to control its closing; S4, setting the working temperature in the heating box (2) to W, and at the same time starting the heating plate (7) in the heating box (2) to increase the temperature, and at the same time turning on the fan (91) and the shutter (92) in the temperature control device (9) to disturb the flow in the heating box (2), and setting the working time of the heating plate (7) and the temperature control device (9) to T. After the T time period, the temperature detection device detects that the temperatures at various positions in the heating box (2) are W1, W2, W3, and W4 respectively; S5, the heating box (2) compares the temperatures at various positions. If the temperatures W1, W2, W3, and W4 are similar, it is determined that the temperature difference in the heating box (2) is small, and the average value of the current temperature in the heating box (2) is recorded as X. Otherwise, it is determined that the temperature distribution in the heating box (2) is uneven, and the heating box (2) continues to be heated. S6, comparing X and W. If X≤0.5W, it is determined that the temperature in the current heating box (2) is too low to meet the heating demand of the car carpet. The heating plate (7) and the control device continue to work for T1 time and then detect again. If X≥1.5W, it is determined that the temperature in the current heating box (2) is too high. The heating plate (7) stops heating. At the same time, the telescopic cylinder (6) controls the door panel (5) to open to dissipate heat inside the heat dissipation box. On the contrary, if 0.5W<X<1.5W, it is determined that the current heating temperature is normal. The device continues to operate for T2 time. S7. After the T2 time period, the telescopic cylinder (6) opens the door panel (5) to dissipate heat inside the box. The heat dissipation time is T3. After the T3 time period, the staff pulls the fabric in the heating plate (7) back to the transfer frame (102) along the loading bracket (101) and the fabric bracket (104), thereby completing the heating of the carpet.
