[0013] Beneficial effects Compared with the prior art, the present invention provides a conveying device for heat treatment of thin steel plates before coating, which has the following beneficial effects: 1. The heating furnace heats the thin steel plate to a certain temperature and then transports it to the insulation furnace. The furnace push plate pushes the thin steel plate into the insulation furnace. After the furnace push plate is moved out, the furnace sealing plate moves downward. When the furnace sealing plate completely seals the insulation furnace, the box push plate can move and push the thin steel plate to move. During the movement of the box push plate, the box sealing plate is driven to move to open the connecting slot. The box push plate pushes the heated thin steel plate into the insulation box. After the box push plate is moved out of the insulation box, the box sealing plate moves to completely seal the insulation box. When the insulation box is completely sealed, the furnace sealing plate can move to open the feed port of the insulation furnace. The insulation place and the feed place of the heated thin steel plate are separated to avoid frequent opening of the insulation equipment when multiple thin steel plates are insulated, which makes the temperature in the insulation unstable and reduces the insulation effect.

[0014] When the lifting rack is engaged with the lifting gear, the gear shifts back to its original position, and the discharging sealing plate moves to close the discharging port. When the lifting rack is engaged with the lifting gear, the gear shifts back to its original position, and the discharging sealing plate moves to close the discharging port. When the lifting rack is engaged with the lifting gear, the gear shifts back to its original position, and the discharging sealing plate moves to close the discharging port. When the lifting rack is engaged with the lifting gear, the gear shifts back to its original position, and the discharging sealing plate moves to close the discharging port. When the lifting rack is engaged with the lifting gear, the gear shifts back to its original position, and the discharging sealing plate moves to close the discharging port.

[0015] 3. The heated thin steel plate enters the insulation box. The four rotating support blocks located at the same height on the bottom of the connecting slot support the four corners of the thin steel plate. The transportation conveyor belt rotates to drive the thin steel plate downward, and the other four rotating support blocks are connected to the same height on the bottom of the slot to support the next thin steel plate entering the insulation box. This reciprocating process allows multiple thin steel plates to enter the insulation box for the insulation process.

The feeding assembly 2 includes a furnace body sealing plate 201, a box body sealing plate 202, a furnace body pushing plate 203 and a box body pushing plate 204. A feeding port is opened at one end of the holding furnace 101. The furnace body sealing plate 201 and the furnace body pushing plate 203 are both arranged at the feeding port. A connecting slot is opened on the side of the holding box 102. The box body sealing plate 202 is vertically slidably installed in the connecting slot. The box body pushing plate 204 is arranged in the holding box 102. The furnace body sealing plate 201 can move vertically to close the insulation furnace 101, the furnace body push plate 203 can move horizontally, the box body sealing plate 202 can move vertically to close the insulation box 102, and the box body push plate 204 can move horizontally; The heat-insulating discharging assembly 3 includes a plurality of heat-insulating transport units 4 and a discharging unit 5. The heat-insulating transport unit 4 includes a transport conveyor belt 401, a lifting rack 402 and a plurality of supporting mechanisms 6. The supporting mechanism 6 includes a rotating support block 601 and a rotating gear 602. The discharging unit 5 includes a discharging push plate 501 and a discharging sealing plate 502. A plurality of transport conveyor belts 401 are rotatably installed in the heat-insulating box 102. The lifting rack 402 is arranged on the side of the transport conveyor belt 401. A plurality of rotating support blocks 601 are arranged on the transport conveyor belt 401. A rotating gear 602 is arranged on the side of the rotating support block 601. The discharging push plate 501 is arranged below the transport conveyor belt 401. A discharging port is opened on the end face of the heat-insulating box 102, and the discharging sealing plate 502 is arranged at the discharging port. The transport conveyor belt 401 can rotate and drive the support mechanism 6 to move. When the rotating gear 602 moves and engages with the lifting rack 402, the rotating gear 602 drives the rotating support block 601 to rotate. When the rotating support block 601 rotates to a point where it cannot rotate, the rotating support block 601 can continue to move and drive the rotating gear 602 to move. The rotating gear 602 drives the lifting rack 402 to move. The movement of the lifting rack 402 can drive the gear sealing plate to move, and the discharge push plate 501 can move horizontally. When in use, the heating furnace 1 heats the thin steel plate to a certain temperature and then transports it to the insulation furnace 101. The furnace body push plate 203 pushes the thin steel plate into the insulation furnace 101. After the furnace body push plate 203 is moved out, the furnace body sealing plate 201 moves downward. When the furnace body sealing plate 201 completely seals the insulation furnace 101, the box body push plate 204 can move and push the thin steel plate to move. During the movement of the box body push plate 204, the box sealing plate 202 is driven to move, so that the connecting slot is opened, and the box body push plate 204 pushes the heated thin steel plate into the insulation furnace 101. The thin steel plate is pushed into the insulation box 102, and after the box pushing plate 204 moves out of the insulation box 102, the box sealing plate 202 moves to completely seal the insulation box 102. When the insulation box 102 is completely sealed, the furnace sealing plate 201 can be moved to open the feed port of the insulation furnace 101. The insulation area and the feed area of ​​the heated thin steel plate are separated to avoid frequent opening of the insulation equipment when multiple thin steel plates are being insulated, which makes the temperature in the insulation unstable and reduces the insulation effect. The heated thin steel plate enters the insulation box 102, and the four rotating support blocks 601 located at the same height of the bottom surface of the connecting slot support the four corners of the thin steel plate. The transportation conveyor 401 rotates to drive the thin steel plate to move downward, and the other four rotating support blocks 601 are connected to the same height of the bottom surface of the slot to support the next thin steel plate entering the insulation box 102.

During the rotation process, the transmission support block releases its support for the thin steel plate, and the thin steel plate falls to On the bottom surface of the inner wall of the insulation box 102, when the rotating support block 601 rotates to a position where it cannot rotate, the rotating gear 602 moves downward and drives the lifting rack 402 to move downward. The lifting rack 402 moves downward and drives the discharge sealing plate 502 to move downward, so that the discharge port is opened, and the discharge push plate 501 moves to push the thin steel plate out of the insulation box 102. When the thin steel plate that has completed the insulation process is moved out of the insulation box 102, the rotating gear 602 contacts the lifting rack 402, the lifting rack 402 moves back to its original position, and the discharge sealing plate moves to close the discharge port; the insulation process is performed on multiple thin steel plates at the same time, and the thin steel plates that have completed the process are pushed out of the insulation box 102 one by one, reducing the opening time of the discharge port of the insulation box 102 and ensuring the stability of the insulation effect.
