[0033] See also Figure 1 - Figure 6 A pneumatic lifting door structure for a stack type coating machine comprises a feed box 1, a closing plate 2 and a connecting component 3. A feed port 11 is arranged on the feed box 1. A fixing plate 4 is arranged on one side of the closing plate 2. A transverse cylinder 5 for pushing the closing plate 2 to close the feed port 11 is arranged on the fixing plate 4. The closing plate 2 is used to block the feed port 11, thereby evacuating the feed box 1. In order to better seal the feed port 11, an installation groove connected end to end is provided around the feed port 11. A rubber sealing ring 12 is arranged in the installation groove. The transverse cylinder 5 pushes the closing plate 2. The rubber sealing ring 12 is pressed to achieve better sealing. The two sides of the fixed plate 4 are connected with longitudinal cylinders 6. The longitudinal cylinders 6 are detachably connected to the fixed plate 4. A handle is fixed on the fixed plate 4. After the fixed plate 4 is disassembled from the longitudinal cylinder 6, it can be easily removed by the handle. The connecting component 3 includes a connecting block 31 fixed to the output end of the transverse cylinder 5 and a plug-in 32 fixed to the closing plate 2. The connecting block 31 is provided with a slot 311 for the plug-in 32 to be longitudinally inserted. By inserting the plug-in 32 into the slot 311, the closing plate 2 is supported and the connection is convenient. The longitudinal cylinder 6 is specifically a rodless cylinder. The rodless cylinder drives the fixed plate 4 to move downward to prevent the fixed plate 4 and the closing plate 2 from falling from a high place, and the downward movement is convenient for repairing or replacing the fixed plate 4 and the closing plate 2. The longitudinal length of the closing plate 2 is greater than the longitudinal length of the fixed plate 4, so that the upper side of the closing plate 2 is higher than the upper end of the closing plate, which is convenient for handholding, and thus convenient for installation and removal.

[0034] The connecting block 31 and the transverse cylinder 5 are respectively located on both sides of the fixed plate 4. The plug-in 32 includes a limiting portion 321 and an inserting portion 322. The top of the inserting portion 322 is fixed to the limiting portion 321. The limiting portion 321 is fixed to the closing plate 2 by screws. The transverse length of the limiting portion 321 is greater than the transverse length of the inserting portion 322. The top of the connecting block 31 supports the limiting portion 321. The limiting portion 321 is provided with an abutting portion 323 on one side facing the fixed plate 4. The limiting strips 33 are fixed on both sides of the fixed plate 4 facing the closing plate 2. The limiting strips 33 are used to limit the closing plate 2, so that the inserting portion 322 can be inserted into the slot 311. Specifically, the limiting strips 33 are in contact with the side of the limiting portion 321, thereby achieving the effect of limiting the closing plate 2. A plurality of transverse cylinders 5 are provided on the fixed plate 4. The connecting component 3 corresponds to the transverse cylinder 5 one by one. In this application, there are four transverse cylinders 5, which are respectively located at the four corners of the fixed plate 4. There are also four connecting components 3, which makes the closing plate 2 more stable.

[0035] A limiting rod 34 passing through the fixed plate 4 is threadedly connected to the closing plate 2, and a guide cylinder 35 passing through the fixed plate 4 is installed on the fixed plate 4. A circular through hole 351 is opened on the guide cylinder 35. The limiting rod 34 is circular, one end of which is connected to a threaded connection part, and the other end is fixed with a polygonal piece that is easy to rotate, so that the threaded connection part is connected to the closing plate 2. Four guide cylinders 35 are also provided. The four guide cylinders 35 guide the four limiting rods 34, and then guide the closing plate 2, further increasing the stability of the closing plate 2, and the limiting rods 34 fix the closing plate 2 longitudinally.

[0036] Both the fixed plate 4 and the closing plate 2 are provided with observation holes 7 , and transparent glass is installed in the observation hole 7 on the closing plate 2 , through which the internal conditions of the feed box 1 can be observed.

[0037] In practice, when feeding is needed, the extended end of the horizontal cylinder 5 moves, pulling the connecting component 3 to move, and the connecting component 3 makes the closing plate 2 move away from the feed port 11 horizontally to prevent friction with the feed port 11, and then the longitudinal cylinder 6 makes the fixed plate 4 and the closing plate 2 move down to expose the feed port 11, which is convenient for feeding. After the fixed plate 4 and the closing plate 2 move down, when the closing plate 2 needs to be repaired or replaced, the limit rod 34 is rotated to separate it from the closing plate 2. When all the limit rods 34 are separated, the closing plate 2 can be moved up. At this time, the limit part 321 is supported by the connecting block 31 to prevent the closing plate 2 from falling. Then, the part of the closing plate 2 that is higher than the fixed plate 4 is pinched to move the closing plate 2 upward. When the insertion part 322 leaves the slot 311, it moves toward the feed port 11 again to prevent the lower limit part 321 from colliding with the upper connecting block 31, and finally the closing plate 2 is moved up. When installing, first place the closing plate 2 between the fixed plate 4 and the feed port 11. When the plug-in 32 is located between the two longitudinal connecting blocks 31, move the closing plate 2 horizontally toward the fixed plate 4, so that the two limiting parts 321 are respectively in contact with the limiting strips 33 on the corresponding sides until the abutting part 323 abuts against the fixed plate 4. At this time, the inserting part 322 and the slot 311 correspond in the longitudinal direction, and the closing plate 2 is moved down until it is supported. Then, the limiting rod 34 passes through the guide cylinder 35 and is threadedly connected to the closing plate 2. When the fixed plate 4 and the closing plate 2 need to be removed together, it is only necessary to separate the fixed plate 4 from the longitudinal cylinder 6.

[0038] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
