A fan 16 is fixedly connected to the top surface of the combined oven 2. The combined oven 2 includes a surface drying oven 3 and an activation oven 4 arranged in sequence. The surface drying oven 3 and the activation oven 4 are separated by a metal partition 5. Heating wires 15 and temperature sensing devices are arranged on the inner tops of the surface drying oven 3 and the activation oven 4. The heating wires 15 are controlled by a single-chip microcomputer. Both sides of the combined oven 2 are closed by box doors 6 with adjustable heights. The box door 6 includes a symmetrically arranged connecting rod device 7 and a door panel 8. A slider 9 is fixedly connected to one side of the door panel 8. A slide rail 10 cooperating with the slider 9 is arranged in the combined oven 2. Limit grooves 11 are symmetrically arranged on both sides of the door panel 8. A first locking member 12 is arranged on the combined oven 2. The locking end of the first locking member 12 extends out of the limit groove 11. The connecting rod device 7 includes a first connecting rod 13 and a second connecting rod 14. The first connecting rod 13 is fixedly connected to the combined oven 2. The second connecting rod 14 is rotatably connected to the door panel 8. The first connecting rod 13 and the second connecting rod 14 are rotatably connected by a rotating shaft. A handle 25 is fixedly connected to the connection part of the second connecting rod 14 and the first connecting rod 13.

[0021] On both sides of the combined oven 2 and above the conveyor device 1, there are negative pressure dust suction covers 17 to prevent the saddle coating from getting dusty after watering and affecting the subsequent bonding effect.

[0022] The conveyor device 1 includes a frame 18. Inside the frame 18, there is a roller 19 driven by a motor, and a metal mesh conveyor belt 20 is sleeved on the roller 19.

[0023] Both ends of the roller 19 are slidably connected to the frame 18 through movable bearing seats. The top surface of the bearing seat is fixedly connected with a second locking member 24. There is a long hole 26 on the top surface of the frame 18 for the second locking member 24 to pass through. When installing or replacing the metal mesh conveyor belt 20, loosen the second locking member 24, push the roller 19 inward along the direction of the long hole 26, remove or put on the metal mesh conveyor belt 20, and then pull the roller 19 outward along the direction of the long hole 26 to ensure the tension of the metal mesh conveyor belt 20.

[0024] Above the frame 18 and below the top surface of the metal mesh conveyor belt 20, there is a metal plate 21 for strengthening support to prevent the saddle from sinking on the metal mesh conveyor belt 20, resulting in insufficient surface drying or activation and affecting the glue bonding quality.

[0025] Metal protection nets 22 are provided above and below the heating wire 15 to prevent impurities from floating into the combined oven 2 and affecting the operation of the heating wire 15.

[0026] The fan 16 includes a fan housing 27. There is a detachable air inlet housing 28 on the fan housing 27. The fan housing 27 and the air inlet housing 28 are connected by a hinge 32. A number of fan-shaped air inlet holes 29 are opened on the air inlet housing 28. An adjusting plate 30 is rotatably connected to the inner side of the air inlet housing 28. A filter screen 31 that fits the shape of the fan-shaped air inlet holes 29 is opened on the adjusting plate 30. A knob 33 for controlling the angle of the adjusting plate 30 is provided outside the air inlet housing 28. When the filter screen 31 coincides with the fan-shaped air inlet holes 29, the air intake volume is the largest. When the filter screen 31 is completely staggered from the fan-shaped air inlet holes 29, the fan-shaped air inlet holes 29 are closed. During use, according to different room temperatures, the air intake area of the fan-shaped air inlet holes 23 can be adjusted by rotating the adjusting plate 28 to change the air intake volume of the fan 16, so as to achieve the effect of adjusting the temperature inside the combined oven 2. When the room temperature is relatively high, reduce the air intake volume of the fan 16. When the room temperature is relatively low, increase the air intake volume of the fan 16. Specific embodiments

[0027] Adjust the spacing of the rotating rollers 19 to install and tension the metal mesh conveyor belt 20. Loosen the first locking member 12, pull the handle 14 to adapt to the heights of saddles of different models. When adjusted to the appropriate height, tighten the first locking member 12. Subsequently, the operator brushes the water-based glue on the surface of the saddle and places the saddle on the metal mesh conveyor belt 20. The saddle first enters the surface drying oven 3, the temperature of the surface drying oven 3 is 40 - 50 °C, and the water-based glue is dried in the surface drying oven 3 for 7 minutes. Then it enters the activation oven 4, the temperature of the activation oven 4 is 80 - 90 °C, and the water-based glue undergoes a temperature increase process in the activation oven 4 for 2 - 3 minutes to ensure that the glue reaches the best bonding effect after exiting the combined oven 2. After the saddle leaves the combined oven 2, the staff conducts the bonding work.

[0028] This design is ingenious. Through the combined oven, the work of evaporating moisture and enhancing the bonding effect of the water-based glue on the surface of the saddle is completed. Moreover, the height of the door panel can be adjusted through the connecting rod device to adapt to saddles of different models. In addition, a rotatable adjusting plate is provided at the air inlet of the fan, and the air intake volume can be adjusted according to the room temperature to ensure that the temperature in the combined oven does not change significantly, guaranteeing the heating effect of the combined oven. Also, the spacing of the rotating rollers can be adjusted to facilitate the installation or replacement of the metal mesh conveyor belt.

[0029] The utility model is not limited to the foregoing specific embodiments. The utility model extends to any new feature or any new combination disclosed in this specification, as well as any new method or process step or any new combination disclosed.
