The implementation principle of the embodiment is as follows: when a worker needs to open the opening 111 of the drying chamber 11 and take and place materials, the limiting block 152 is unscrewed, the limiting rod 151 is rotated to be separated from the limiting groove 24 on the end cover 2, then the end cover 2 is pulled outwards until the first annular plate 21 completely moves to the outer side of the drying chamber 11, at this time, the sliding block 23 at the end part of the guide rod 22 moves to the part, close to the opening 111, of the guide groove 12 and enters the sliding groove 13, then the worker vertically moves the end cover 2 downwards through the sliding block 23 and the sliding groove 13, the height of the roller 35 at the hinged position of the first connecting rod 311 and the second connecting rod 331 is reduced while the roller 35 rotates to drive the sliding block 33 to vertically move upwards, the first spring 321 is stretched and the second spring 322 is extruded during the vertical upward movement of the sliding block 33, the positioning pin 41 is extruded by the arc-shaped guiding surface 411 at the end part of the positioning pin 41 and the third spring 43 is, until the sliding block 33 continues to move upwards and the positioning pin 41 automatically enters the inside of the positioning slot 332 under the action of the spring force of the spring three 43 to position the position of the sliding block 33, so that the sliding block 33 and the end cover 2 do not move any more. When the worker finishes taking and placing the materials in the drying chamber 11 and needs to seal the opening 111 of the drying chamber 11, one end of the positioning pin 41 far away from the positioning groove 332 is pulled to enable the end part to be separated from the positioning groove 332, the first spring 321 is in a stretching state and the second spring 322 is in a shrinking state, so that the sliding block 33 can vertically move downwards and drive the end cover 2 to move upwards, when the worker lifts the end cover 2 to the original height, the end cover 2 is pushed inwards to enable the annular convex block 211 to be embedded into the annular groove 1121, then the limiting rod 151 is rotated to enable the limiting rod to enter the limiting groove 24, and finally the limiting block 152 is screwed up to enable the end cover 2 to be closely attached to the side wall of the machine body 1.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by the embodiments, therefore: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
