[0056] Further comprising two pushing frames 26, the top of each of which is horizontally provided with a pushing cylinder 27, and the piston rods of the two pushing cylinders 27 are connected with the first pushing rod 13 and the second pushing rod 14 respectively.

[0057] The top of the transmission trolley 7 is vertically provided with a support plate 28 on both sides, and the inner side of the support plate 28 is parallelly provided with a plurality of support bars 29, and an open upward cover-shaped material receiving frame 30 is horizontally arranged between the opposite two support bars 29, and the bottom of the material receiving frame 30 is porous for supporting the material to be dried.

[0058] The hot air circulation oven provided by the utility model, when the material is dried by hot air, firstly, the material is placed on the transmission trolley 7, and then the transmission trolley 7 is sent into the oven body 1 through the upstream end material passing port 2, and at the same time, the hot air in the hot air inlet pipe 3 is blown into the heated hot air by the air blower (for example, the outside of the hot air inlet pipe 3 is connected with the electric air blower), so that the hot air can act on the material to be dried from top to bottom; at the same time, the hot air in the first oven body 1 flows into the second oven body 1 after passing through the first hot air transmission pipe 4, and the material to be dried in the second oven body 1 is dried; and after drying, the hot air enters the next oven body 1 through the hot air transmission pipe 4, and finally is discharged outward through the hot air outlet pipe 5; during the whole drying process, the transmission trolley 7 is also movable, so that the same transmission trolley 7 can be dried by hot air when passing through each oven body 1, so that better drying effect can be achieved, and the hot air is consumed to a sufficient degree because it is used for drying multiple materials, so the energy waste is small, so that the energy consumption required for drying the same material is low.

[0059] In another embodiment, the direction of the hot air is opposite to the direction of the transmission trolley 7, that is, the transmission trolley 7 enters the oven body 1 from the downstream end material passing port 2 and finally moves out of the oven body 1 from the upstream end material passing port 2; in this way, when the material is relatively high in humidity, the hot air with relatively low temperature and relatively high humidity is used for drying (compared with the material, the hot air has relatively low humidity and high temperature, so it still has drying effect); and as the material continues to move, the temperature of the hot air acting on the material is higher and the humidity is lower, and finally the material can reach the required dryness. When the transmission trolley 7 enters the oven body 1, it can be considered as preheating and pre-drying by using excess heat, so that the method can also reduce energy consumption under the premise of drying the material to the required dryness.

[0060] Wherein the active power of the transmission trolley 7 on the transmission rail 6 and the return rail 10 is the first push rod 13 and the second push rod 14; that is, during drying, the first push rod 13 pushes the transmission trolley 7 on the first active rail 11 to the transmission rail 6, and in the pushing process, the pushed transmission trolley 7 collides with the transmission trolley 7 on the transmission rail 6 and pushes the transmission trolley 7 a certain distance; at the same time, the transmission trolleys 7 on the transmission rail 6 are sequentially attached, so that under the action of the pushing force of the first push rod 13, all the transmission trolleys 7 on the transmission rail 6 can move forward by a distance of the width of a transmission trolley 7. At this time, not only is the position of all the transmission trolleys 7 in the oven body 1 adjusted, but also the transmission trolley 7 at the end of the transmission rail 6 (which has completed drying) is pushed to the second active rail 12.

[0061] Then the second motor 21 and the second screw rod 22 drive the second translation seat 20 to move, and move the transmission trolley 7 that has completed drying to the unloading anti-falling plate 25. At this time, the transmission trolley 7 is limited by the second anti-falling plate 24 and the unloading anti-falling plate 25 on both sides, so the position can be stably maintained. Workers can manually take down the drying completed receiving frame from the support plate 28 and place a new material receiving frame 30 to be dried.

[0062] After the new material receiving frame 30 to be dried is placed, the second motor 21 and the second screw rod 22 move the second active rail 12 to the state of being butt-jointed with the end of the return rail 10. Then the second push rod 14 pushes the transmission trolley 7, and at the same time, all the transmission trolleys 7 on the return rail 10 are to be dried. Therefore, the second push rod 14 pushes the transmission trolley 7 on the return rail 10, and at the same time, the transmission trolley 7 at the end of the return rail 10 is pushed to the first active rail 11 that is butt-jointed with the return rail 10.

[0063] Then the first motor 17 and the first screw rod 18 move the first translation seat 16 and the first translation rail 15 to the end of the transmission rail 6, so as to form a cycle and realize efficient drying of the material. Moreover, when the hot air enters the oven body 1 through the hot air inlet pipe 3 or the hot air transmission pipe 4, it will first be affected by the air distribution plate 9. Since the air distribution plate 9 is porous, it can divide the hot air and make the hot air act uniformly on the material to be dried, thereby ensuring the drying effect.

[0064] The above description is only a description of the preferred embodiment of the present application, and does not limit the scope of the present application in any way. Any modification or modification of the above disclosure by a person skilled in the art belongs to the protection scope of the claims.
