[0006] According to the above technical solution, the side of the fixing claws close to each other is set as an arc surface, and the fixing claws are in contact with the lifting plate. By setting one side of the fixing claws as an arc surface, it is convenient to grab the valve.

[0007] According to the above technical solution, the protrusion is in contact with the lifting plate, and a reset spring is fixedly installed between the connecting rod and the L-shaped plate. This arrangement has the effect of centering the valve, avoiding the inability to complete the stacking of the valve due to the displacement of the valve position.

[0008] According to the above technical solution, the buffer device includes an inclined block, a moving block, a long rod, a square plate, gas cylinder 1, gas cylinder 2, a short plate, a short rod, a splint, a contact plate, a spring and a slider. The storage box is provided with movable grooves on the left and right sides. The gas cylinder 1 is fixedly installed on the left and right sides of the storage box. The square plate is slidably installed inside the gas cylinder 1. The long rod is fixedly installed on the top of the square plate. The long rod slides through the top of the gas cylinder 1. The moving block is fixedly installed on the top of the long rod. The inclined block is slidably installed on the side of the moving block close to the storage box.

By setting the fixing device, the valves are wrapped by the inflated rubber blocks after they are stacked, so as to prevent the stacked valves from moving inside the storage box.

[0012] According to the above technical solution, a reset spring four is fixedly installed between the movable plate and the gas cylinder three, the movable rod is in contact with the connecting plate, and the movable rod is in contact with the cover plate. The movable plate is reset by setting the reset spring four, and the roller is controlled by the contact between the movable rod and the connecting plate.

[0013] A method for using a stacking device for facilitating valve placement includes the following steps: Step 1: The staff manually moves the valve to the lifting plate, turns on the power, and moves the fixed claws. After the fixed claws fix the valve, the staff confirms again that the fixed claws clamp the valve; Step 2: After confirming that the valve is clamped, start the power device, which drives the lifting plate to move, and the movement of the lifting plate drives the valve to move upward, so that the lifting plate drives the valve to move to the top port of the storage box; Step 3: After the staff confirms that the lifting plate is flush with the top port of the storage box, the electric push rod is started, and the electric push rod pushes the push plate to move, so that the valve moves. When the valve moves to the top of the storage box, the staff confirms that the valve position is correct and releases the clamping of the fixed claw on the valve, and the valve enters the storage box; Step 4: After the staff confirms that the valve position is correct and releases the clamping of the fixed claw on the valve, the valve falls into the storage box, the valve is stacked inside, and the cover is closed to complete the stacking of the valve.

[0014] The present invention provides a stacking device that is convenient for placing valves. It has the following beneficial effects: (1) In the invention, the power device is started, so that the power device drives the lifting plate to rise, and at the same time the fixed claw clamps the valve, so that the valve will not be moved by force when it rises and cause it to fall. After the valve is clamped, the lifting plate rises, and the lifting plate rises and contacts the protrusion. The lifting plate continues to rise, causing the protrusion to move. The movement of the protrusion drives the connecting rod to move, and the movement of the connecting rod drives the positioning plate to move. When the lifting plate continues to rise and does not contact the protrusion, the protrusion, the connecting rod and the positioning rod are reset by the elastic force of the reset spring sheet, so that the positioning rod is reset. The positioning rod is reset and contacts the valve. The reset of the positioning rod pushes the valve to the center position, thereby preventing the valve from being improperly positioned and unable to enter the storage box.

[0015] (2) In the present invention, when the valve falls into the storage box, the valve contacts the inclined surface block, so that the valve drives the inclined surface block to move downward, and the downward movement of the inclined surface block drives the moving block to move, thereby controlling the speed at which the valve descends and avoiding collision caused by the valve descending too fast, thereby causing damage to the valve surface. The movement of the moving block drives the long rod to move, and the movement of the long rod drives the square plate to move. The movement of the square plate squeezes the gas inside the first gas cylinder. The gas inside the first gas cylinder flows into the second gas cylinder through the first conduit, thereby moving the short plate. The movement of the short plate drives the movement of the short rod. The movement of the short rod drives the movement of the clamping plate. The movement of the clamping plate drives the movement of the contact plate. The contact plate moves and contacts with the valve. The friction force generated by the contact of the contact plate with the valve causes the valve to slowly descend, thereby completing the stacking of the valves.

[0016] (3) In the invention, the cover is closed and the cover rotates to drive the moving rod to move. The movement of the moving rod drives the moving plate to move. The movement of the moving plate squeezes the gas inside the gas cylinder three. The squeezed gas enters the rubber block through the conduit two. The gas enters the rubber block and inflates the rubber block. The expanded rubber block wraps the valve to prevent the stacked valves from moving inside the storage box and prevents the valves from colliding with each other during movement, causing damage to the valve surface. At the same time, when the moving block moves, the movement of the moving block drives the movable rod to move. The movable rod moves and contacts the connecting plate. The movable rod continues to move to move the connecting plate. The movement of the connecting plate drives the stop rod to move. The movement of the stop rod releases the limit on the roller, allowing the invention to move freely. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The top of the inclined plane block 501 is set as an inclined plane, and a reset spring 1 is fixedly installed between the inclined plane block 501 and the moving block 502, and a reset spring 2 is fixedly installed between the moving block 502 and the gas cylinder 1 505.

[0026] A method for using a stacking device for facilitating valve placement includes the following steps: Step 1: The staff manually moves the valve onto the lifting plate 403, turns on the power, and moves the fixing claw 407. After the fixing claw 407 fixes the valve, the staff confirms again that the fixing claw 407 clamps the valve; Step 2: After confirming that the valve is clamped, start the power device 402, the power device 402 drives the lifting plate 403 to move, the lifting plate 403 moves and drives the valve to move upward, so that the lifting plate 403 drives the valve to move to the top port of the storage box 2; Step 3: After the staff confirms that the lifting plate 403 is flush with the top port of the storage box 2, the electric push rod 405 is started, and the electric push rod 405 pushes the push plate 406 to move, so that the valve moves.

[0027] When the embodiment is working, when the valves need to be stacked, the worker places the valves on the top of the lifting plate 403, the power device 402 is started, so that the power device 402 drives the lifting plate 403 to rise, and at the same time the fixed claw 407 clamps the valve. After the valve is clamped, the lifting plate 403 rises, and the lifting plate 403 rises and contacts the protrusion 410. The lifting plate 403 continues to rise, so that the protrusion 410 moves. The movement of the protrusion 410 drives the connecting rod 409 to move. The movement of the connecting rod 409 drives the positioning plate 411 to move. When the lifting plate 403 continues to rise and does not contact the protrusion 410, the positioning plate 411 moves. When in contact, the protrusion 410, the connecting rod 409 and the positioning plate 411 are reset by the elastic force of the reset spring sheet, so that the positioning plate 411 is reset and contacts the valve. When the lifting plate 403 rises to be flush with the top of the storage box 2, the electric push rod 405 is started and the free end of the electric push rod 405 is extended.
