Further, in order to enable the axial movement of the gate to be smoother, the bottom end of the gate is provided with at least two pulleys 7, and a sliding rail 8 matched with the pulleys 7 is arranged below the gate.

Meanwhile, one side of the gear box 2 is connected with a first air cylinder 5 through a connecting block 4, an output shaft of the first air cylinder 5 is connected with the connecting block 4, when the first air cylinder 5 stretches radially, the connecting block 4 can drive the whole gear box 2 and the driving motor 3 to move radially, so that the screw rod 1 drives the gate to move radially in the direction perpendicular to the screw rod 1, namely, in the radial direction of the equipment cavity, the gate and the equipment cavity are compressed or relaxed. Further, the connection block 4 is provided with a plurality of long holes 41, the top end of the equipment cavity connected with the gate is provided with a limit block 42, the limit block 42 is provided with limit posts 43 matched with the plurality of long holes 41, each limit post 43 passes through the long hole 41 at a corresponding position, namely, the telescopic distance of the first air cylinder 5 limits the length of the hole of the long hole 41, on one hand, excessive telescopic of the first air cylinder 5 is avoided, so that the connection between the gate and the equipment cavity is too tight or too loose; on the other hand, the first cylinder 5 can be prevented from generating axial shaking, and the connection between the gate and the equipment cavity is prevented from being influenced.

Further, two sides of the gate are provided with an automatic aligning assembly 9, the automatic aligning assembly 9 comprises a fixing piece 91 and a movable piece 92, a groove 911 is formed in the fixing piece 91 from bottom to top, one end of the movable piece 92 is provided with a protruding block 921 embedded into the groove 911, the top end of the protruding block 921 is in an arc design, and the other end of the movable piece 92 is provided with a supporting piece 93 extending to the bottom end of the gate.
