The movement of the first movable plate 1302 can drive the first piston 1306 to move. When the first movable plate 1302 and the first piston 1306 move under the extension of the electric telescopic rod 1301, the second piston 1310 moves upward under the action of oil pressure, thereby driving the blowing pipe 8 to move upward. When the first movable plate 1302 and the first piston 1306 move under the contraction of the electric telescopic rod 1301, the second piston 1310 and the blowing pipe 8 move downward.

[0034] In this embodiment, Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a slide groove 1402 is provided on the top of the bracket 1401, and slots 1403 are symmetrically provided on both sides of the slide groove 1402. The slots 1403 are evenly spaced on both sides of the slide groove 1402. The bracket 1404 is slidably connected to the slide groove 1402, and both sides of the bracket 1404 are penetrated by extrusion rods 1405. The outer end of the extrusion rod 1405 is fixed with a pressing block 1406. A pull rope 1407 is fixed in the bracket 1404, and the pull rope 1407 passes through the two extrusion rods 1405 and is connected to the moving column 1408. The moving column 1408 is pulled by The extension spring 1409 is connected to the inside of the bracket 1404, and an extrusion block 1410 is fixed to the bottom of the movable column 1408. When installing the bracket 1404, it is necessary to pinch the two pressing blocks 1406. The extrusion rod 1405 moves with the pressing block 1406 and squeezes the pull rope 1407. The movable column 1408 and the extrusion block 1410 move upward under the pulling action of the pull rope 1407. After the bracket 1404 is installed, the two pressing blocks 1406 can be released, and the movable column 1408 and the extrusion block 1410 automatically rebound under the action of the extension spring 1409.

[0035] In this embodiment, Figure 4 、 Figure 6 and Figure 7As shown, a channel 1411 is opened on the bracket 1404, and the two sides of the channel 1411 are symmetrically slidably connected to the limit blocks 1412. The limit blocks 1412 are connected to the bracket 1404 through the first compression spring 1413. The extrusion block 1410 is located between the two limit blocks 1412. The outer end surface of the limit block 1412 is fixed with a card block 1414. The card block 1414 is connected to one of the card slots 1403. When the two pressing blocks 1406 are pinched, the moving column 1408 And the extrusion block 1410 moves up, the limit block 1412 shrinks into the channel 1411 under the action of the first compression spring 1413, and the bracket 1404 is extended into the slide groove 1402 and slid back and forth to adjust the position of the bracket 1404, then the two pressing blocks 1406 are released, the moving column 1408 and the extrusion block 1410 bounce down, the extrusion block 1410 squeezes the two limit blocks 1412 to move, and the card block 1414 is locked in the corresponding card slot 1403, which is convenient for locking the bracket 1404.

[0036] In this embodiment, Figure 2 、 Figure 4 and Figure 5 As shown, the bracket 1401 is connected to the inner bottom of the drying chamber body 1 through the second compression spring 1415, and a third piston 1417 is fixed to the bottom of the bracket 1401, and a third oil cylinder 1416 is fixed to the bottom of the groove 3. The third piston 1417 is slidably connected in the third oil cylinder 1416, and the second compression spring 1415 supports the bracket 1401. After the pulp molded product is placed on the bracket 1404, the bracket 1401 sinks under the weight, and the third piston 1417 moves downward and presses out the hydraulic oil in the third oil cylinder 1416.

At the same time, the movement of the first movable plate 1302 drives the first piston 1306 to move, and the second piston 1310 moves upward under the action of oil pressure, and the blowing duct 8 moves upward. The staff enters the main body 1 of the air drying chamber. Multiple brackets 1404 can be installed on each bracket 1401. When installing the bracket 1404 It is necessary to pinch the two pressing blocks 1406, and the squeezing rod 1405 moves with the pressing block 1406. The moving column 1408 and the squeezing block 1410 move upward under the pulling action of the pull rope 1407, and the limit block 1412 automatically retracts into the channel 1411. After the bracket 1404 is placed into the slide groove 1402 and the position of the bracket 1404 is adjusted, the two pressing blocks 1406 are released, and the moving column 1408 and the squeezing block 1410 automatically bounce down and push open the two limit blocks 1412, and the card block 1414 is locked into the corresponding The brackets 1401 are arranged in the slots 1403, thereby locking the brackets 1404. Every two brackets 1401 are set as a group. A row of pulp molded products can be placed on each group of brackets 1401. Every four brackets 1404 support one pulp molded product. When placing the pulp molded products, the crossbars on the pulp molded products can be placed on the brackets 1404. In the process of placing the pulp molded products, the brackets 1401 sink under the weight, the third piston 1417 moves downward, the fourth piston 1420, the second movable plate 1421 and the seal 1422 move upward and Open the air blowing port 9, place the pulp molded products, and then leave the drying chamber main body 1. The electric telescopic rod 1301 contracts to drive the first movable plate 1302 to move, and the two revolving doors 2 rotate and close. At the same time, the blowing duct 8 moves down and closes to the pulp molded products. Then the adjustable hot air blower 6 is put into operation, and the blowing duct 8 and the air blowing port 9 blow hot air downward to dry the pulp molded products. The wind speed of the adjustable hot air blower 6 is adjustable, and the exhaust fan 11 can be used to exhaust air. The drained liquid flows into the groove 3, and the liquid can be discharged after opening the drain valve 5.
