In order to avoid the cover body entering into the mounting chamber 15, the isolation mesh plate 152 is fixedly installed at the opening of the mounting chamber 15.

[0045] In the process of drying the cover, the cover enters the drying cavity 12 through the feeding port 13 at the top of the drying box 1, and the cover will bounce or slide down along the guide plate 2 after falling on the guide plate 2. In this process, the cover will vibrate after falling on the guide plate 2, which will cause some water droplets attached to the cover to separate from the cover. After the water droplets separate, they fall on the water absorption pad 3 and are absorbed. At the same time, when the cover contacts the water absorption pad 3, the water droplets on the cover at the contact position between the cover and the water absorption pad 3 will also be absorbed by the water absorption pad 3. In combination with the high temperature effect of the heating device 151 in the drying cavity 12, the cover will be quickly dried, thereby reducing the occupied area of the drying equipment and improving the production efficiency of the aluminum plastic cover. At the same time, the setting of the water absorption pad 3 can also avoid damage to the cover after the cover hits the guide plate 2 as much as possible.

[0046] With reference to Figure 2 , in order to further optimize the drying effect, the plurality of guide plates 2 in the drying cavity 12 are arranged in two groups, and the two groups of guide plates 2 are arranged on the inner walls of the drying cavity 12 facing each other, and the plurality of guide plates 2 in the same group are uniformly and spacedly arranged from top to bottom, and the plurality of guide plates 2 in the two groups are alternately arranged.

Specifically, the driving mechanism 4 includes a roller 41 rotatably connected to the drying box 1, and a driving motor 42 fixedly connected to the drying box 1 and used to drive the roller 41 to rotate. The water absorption pad 3 is wound on the roller 41. With the continuous feeding of the cover into the drying box 1, the water absorption pad 3 in the drying box 1 will gradually be saturated with water. In this case, the driving motor 42 can be used to drive the water absorption pad 3 to rotate, so that the wet water absorption pad 3 in the drying box 1 is replaced, thereby improving the drying efficiency of the cover.

The guide plate 2 is fixed to the drying cavity 12 through the elastic member 21. The vibration of the guide plate 2 is excited after the cover body falls on the guide plate 2, and the vibration of the guide plate 2 also excites the vibration of the cover body, so as to accelerate the falling of the water drops on the cover body and speed up the drying of the cover body.

[0055] Referring to Figure 5 Further, a plurality of elastic members 34 are arranged between the leading end and the trailing end of the water absorption pad 3, and the elastic members 34 connect the leading end and the trailing end of the water absorption pad 3 together. In this way, when the guide plate 2 vibrates, the water absorption pad 3 will have a buffer space, thereby increasing the stability of the water absorption pad 3.

[0056] Referring to Figure 9Specifically, the water absorption pad 3 includes two splicing parts 33, for the convenience of description, the two splicing parts 33 are named as splicing part 33 one and splicing part 33 two, the two ends of the splicing part 33 are provided with a plurality of connecting holes 333, in order to increase the stability of the water absorption pad 3, the connecting holes 333 are provided to the reinforcing ribs 32.

At the same time, the length of the single splicing part 33 meets the normal working and use requirements of the water absorption pad 3 in the drying cavity 12.

[0057] When the water absorption pad 3 needs to be replaced, first ensure that one of the splicing parts 33 is completely located in the drying cavity 12 and the two ends are out of the drying cavity 12, and then the other splicing part 33 is separated from the working splicing part 33 for replacement. In this way, the uninterrupted operation of the drying equipment is ensured, and the replacement of the water absorption pad 3 is realized.

[0058] Referring to Figure 2 and Figure 10 , the drying box 1 is provided with two groups of drying equipment, and the two groups of drying equipment are respectively corresponding to the two water absorption pads 3.

[0059] The fan 82 can extract the air in the drying chamber 81 and the heat in the air to the drying chamber 81, and then discharge it through the air outlet. In this process, a hot air flow is formed in the drying chamber 81 to dry the humid water absorption pad 3 in the drying chamber 81, and the drying of the water absorption pad 3 in the drying chamber 81 is accelerated, and the waste heat utilization in the drying chamber 81 is realized. At the same time, a hot air flow is also formed in the drying cavity 12, which accelerates the drying efficiency of the cover in the drying cavity 12. At the same time, since the air flow in the drying cavity 12 is from bottom to top, the hot air flow in the drying cavity 12 collides with the movement track of the cover in the drying cavity 12, which accelerates the drying efficiency of the cover.

[0060] Referring to Figure 10 and Figure 11Further, the drying bin 8 comprises a base part 83 and two adjusting parts 85, the base part 83 is fixedly connected to the middle part of the drying bin 8, the two adjusting parts 85 are respectively arranged on the upper and lower sides of the base part 83, the adjusting part 85 is sleeved to the periphery of the base part 83, and the adjusting part 85 and the base part 83 are in sliding connection, and the fan 82 is installed to the adjusting part 85 at the bottom of the drying bin 8.

[0061] The side wall of the drying box 1 is vertically provided with a track 18, the adjusting part 85 is in sliding connection to the track 18, and the side of the two adjusting parts 85 away from each other, that is, the bottom and the top of the drying bin 8 are provided with a replacement window 851, and the replacement window 851 is provided with a detachably installed door plate 852, and the door plate 852 and the drying bin 8 are connected by screws or the like.

In addition, the high temperature in the drying cavity 12 and the airflow generated by the fan 82 will cause the cover to dry quickly. With the continuous feeding of the cover into the drying box 1, the water absorption pad 3 in the drying box 1 will gradually become saturated. When the humidity detector detects such a situation, it will feed back to the controller 7. The controller 7 can drive the water absorption pad 3 to rotate by driving the motor 42, and the water absorption pad 3 in the drying cavity 12 is rotated. When the water absorption pad 3 needs to be replaced, open the door plate 852 and make the adjusting part 85 of the drying bin 8 slide down, so that the roller 41 is separated from the adjusting part 85. At this time, the normal work of the drying bin 8. Then make sure that one of the spliced parts 33 is completely wrapped around the roller 41, then separate the spliced part 33 on the roller 41 from the spliced part 33 in the working state, and then replace the spliced part 33 on the roller 41.
