The push rods 30 are inserted into the drying rack 26, and the push rods 30 are not fitted with the drying rack 26 and the third connecting rod 25. The upper ends of the push rods 30 extend to the interior of the drying rack 26. A second movable groove 20 is provided on one side of the drying box 1, and third movable grooves 21 are provided on both sides of the drying box 1. The second movable groove 20 is connected to the third movable groove 21 on the same side. The inner cavity of the second movable groove 20 is rotatably connected to a turntable 22. The rotating shaft of the turntable 22 passes through the outside of the drying box 1 and is fixedly connected to the second circular gear 19.

[0025] The working principle of the present invention is as follows: when in use, the staff pulls the first pull rope 5 to drive the upper first baffle plate 4 to rotate, so that when the staff waits for the foam packages in the drying system to be dried, multiple foam packages are arranged one by one and sent into the drying box 1 at one time, which reduces the waiting time of the drying system when the foam packages are loaded and unloaded, improves the drying efficiency of the foam packages, reduces the waiting time of the drying system, and saves energy. The foam packages arranged in a row at the upper end of the feed plate 3 slide together between the first baffle plate 4 and the drying box 1, and then the pulling of the first pull rope 5 is released to make the first baffle plate 4 return to its original position. The staff arranges a row of foam packages to be dried at the upper end of the feed plate 3 again, reducing the opening time of the first baffle plate 4 and the heat loss in the inner cavity of the preheating box 2. After starting the motor 16, the motor 16 drives the semi-gear 15 to rotate, so that the semi-gear 15 passes through the first circular gear 14 and the second circular gear 14. The belt group 13 and the first belt group 12 drive the rotating shaft 11 to rotate, so that the rotating shaft 11 reels in the second pull rope 9, so that the second pull rope 9 drives the second baffle 8 to move toward the inner cavity of the first moving groove 7, and then the foam packaging between the first baffle 4 and the drying box 1 slides through the connecting hole 6 into the drying box 1 for drying. The foam packaging dried in the drying box 1 falls from the other side of the drying box 1 into the preheating box 2. After the second baffle 8 rises to the top of the first moving groove 7, the first circular gear 14 and the half gear 15 are no longer engaged, and the pulling force on the second baffle 8 is lost. At this time, the second baffle 8 falls downward under the action of its own gravity, so that the inner cavity of the drying box 1 is sealed again, and the foam packaging is dried, so that the foam packaging in the drying box 1 can be loaded and unloaded by itself, which improves the loading and unloading speed of the foam packaging, reduces the waiting time of the drying system during operation, and improves the drying efficiency of the foam packaging.

[0026] The dried foam packaging dropped from the drying box 1 will drop to one end of the conveying belt set 17, and then the half gear 15 drives the second circular gear 19 to rotate, and the second circular gear 19 drives the conveying belt set 17 to rotate through the third belt set 18, and the foam packaging at the upper end of the conveying belt set 17 is transported to between the first baffle plate 4 and the drying box 1 and then taken out, thereby extending the retention time of the dried foam packaging in the preheating box 2, so that the residual heat on the dried foam packaging can be dissipated into the preheating box 2, and then dissipated to the upper end through the holes opened in the feed plate 3 to preheat the foam to be dried between the upper first baffle plate 4 and the drying box 1, and the preheating of the dried foam packaging can be utilized, so as to improve the drying efficiency of the foam packaging.

[0027] When the second circular gear 19 rotates, the turntable 22 is driven to rotate, so that the turntable 22 drives the second connecting rod 24 and the third connecting rod 25 to move through the first connecting rod 23, and the moving position of the third connecting rod 25 and the drying rack 26 is limited by the third moving groove 21, so that the foam package entering the drying box 1 through the connecting hole 6 will fall into the drying rack 26, and then the third connecting rod 25 drives the foam package to move in the inner cavity of the drying box 1 through the drying rack 26, and after the drying rack 26 is driven to the bottom end of the drying box 1 by the third connecting rod 25, one end of the drying rack 26 is lifted by the first pushing plate 29, so that the drying rack 26 rotates around the third connecting rod 25, which is convenient for the foam package in the drying rack 26 to enter and exit, so that the foam package can be automatically loaded and unloaded, thereby improving the drying efficiency of the foam package. After the third connecting rod 25 drives the drying rack 26 to move upward, the drying rack 26 loses the effect of the first pushing plate 29 and will return to its original position under the action of the reset spring 27, so that The position of the foam packaging in the drying rack 26 is stable, which prevents the foam packaging from falling when the drying rack 26 moves, so that a variety of foam packaging of different specifications can be placed in the drying rack 26, which is more practical. After the third connecting rod 25 drives the drying rack 26 to rise to the top, the drying rack 26 on one side of the drying box 1 is pushed by the second pushing plate 31 to seriously turn the third connecting rod 25 over, and then the foam packaging in the drying rack 26 on one side will fall into the drying rack 26 on the other side of the drying box 1. After that, the third connecting rod 25 and the drying rack 26 are driven to move downward, and the foam in the drying rack 26 on the other side of the drying box 1 falls to the upper end of the conveying belt group 17 through the connecting hole 6, and the drying rack 26 on one side of the drying box 1 is put into the foam packaging again for drying, so that the foam packaging moves up and down in the inner cavity of the drying box 1 for drying, and the drying effect is better. The push rod 30 can help the foam packaging in the drying rack 26 to fall out of the drying box 1, so as to ensure the smooth feeding and discharging of the foam packaging.
