Description

Technical Field

[0001] This invention relates to the field of injection molded part storage and conveying equipment, and in particular to a multi-layer stacked storage and conveying rack for gas detector injection molded parts. Background Technology

[0002] In the production process of injection-molded gas detector parts, the molded parts need to be placed on the surface of a support tray and stacked using a multi-layer stacking storage conveyor to facilitate downstream assembly processes. Currently, the traditional multi-layer stacking storage conveyor used in the industry only has a vertical limiting and protective structure for the support tray, which can only prevent the support tray from falling, but does not have a corresponding horizontal inter-layer positioning and retention structure.

[0003] After the injection molded parts are demolded, the surface of the parts is coated with release agent, resulting in an extremely low coefficient of friction. The inertial loads generated during the stacking and lifting of the support trays and the frequent start-ups and shutdowns of the equipment cause the parts to slide slightly off the surface of the support trays, leading to horizontal interlayer slippage of the entire support tray. While the magnitude of this slippage is small and difficult to detect in a single instance, it accumulates and amplifies during continuous multi-layer stacking cycles, eventually causing interlayer misalignment and stacking jamming. In severe cases, it can cause the support trays to slip and fall, forcing the equipment to stop for maintenance. This significantly reduces the efficiency of injection molded part stacking and storage, disrupting the continuity of the production line and the stability of storage. Summary of the Invention

[0004] The purpose of this application is to provide a multi-layer stacking storage and conveying rack for injection molded gas detector parts, which has the advantages of automatic multi-layer stacking guidance, self-conversion of lifting power and air pressure locking, pressure relief cycle protection, synchronous completion of lifting guidance and locking, and vertical support and horizontal inter-layer linkage locking. It achieves the effects of maintaining the horizontal inter-layer position of the bearing plate, reducing the risk of inter-layer slippage and misalignment, smooth multi-layer stacking action, and improving operational safety.

[0005] To achieve the above objectives, this application provides the following technical solution: a multi-layer stacking storage and conveying rack for injection molded gas detector parts, comprising: The storage and conveying frame includes a top material mechanism and a limiting mechanism disposed inside the storage and conveying frame. The storage and conveying frame includes a base frame, support legs, a limiting frame and a conveying port. The storage and conveying frame is provided with a plurality of bearing plates inside. The gas detector injection molded part body is placed inside the bearing plate. The bearing plate is provided with a guide structure for maintaining the horizontal interlayer position. The guide structure includes a rod fixedly connected to the top of the bearing plate and a sleeve sleeved outside the rod. A buffer airbag ring is fixedly connected to the top of the rod. A ball top rod is slidably inserted inside the sleeve. An abutment plate is fixedly connected to one end of the ball top rod. The abutment plate is located outside the rod. It also includes a displacement structure and a transmission structure. The displacement structure is disposed outside the socket and is used to drive the ball top rod to extend or retract radially along the socket so that the abutment plate abuts or releases the rod. The transmission structure is disposed outside the displacement structure and is used to convert the lifting power of the top material mechanism into the radial driving force of the displacement structure.

[0006] Preferably, the insertion rod is fixedly connected to the top of the carrier plate, and the insertion sleeve is fixedly connected to the bottom of the carrier plate, for guiding docking when two adjacent sets of carrier plates are stacked and stored. The abutment plate is arc-shaped, and a compression spring is fixedly connected between the end of the ball top rod away from the abutment plate and the outer wall of the sleeve. The compression spring is sleeved on the outside of the ball top rod.

[0007] Preferably, the displacement structure includes a sleeve fixedly connected to the outside of the insert and a piston ring slidably connected to the inside of the sleeve. A tension spring is fixedly connected between the top of the piston ring and the inner top wall of the sleeve. A displacement sleeve penetrating the sleeve is fixedly connected to the bottom of the piston ring. A wedge-shaped sleeve is fixedly connected to the bottom of the displacement sleeve. The wedge-shaped sleeve has a wedge-shaped surface inside and is located outside the ball top rod. A sealing gasket adapted to the displacement sleeve is fixedly connected inside the sleeve. The piston ring, the displacement sleeve, and the wedge-shaped sleeve are all slidably connected to the outside of the insert.

[0008] Preferably, the sleeve is fixedly connected to a pressure relief pipe, and the initial position of the piston ring is located above the pressure relief pipe; When the piston ring moves downward under the transmission structure, the piston ring drives the displacement sleeve and the wedge sleeve to move downward. The wedge sleeve drives the ball top rod and the abutment plate to move into the insert sleeve, thereby achieving the external limiting of the insert rod by the abutment plate.

[0009] Preferably, the transmission structure includes a corrugated guide plate fixedly connected to the inner wall of the limiting frame and a piston cylinder fixedly connected to the outside of the sleeve. A stop plate is slidably connected inside the piston cylinder, and a reciprocating rod passing through the piston cylinder is fixedly connected to the outside of the stop plate. The end of the reciprocating rod away from the stop plate slides against the corrugated surface of the corrugated guide plate. As the sleeve rises along with the insert and the bearing plate, the reciprocating rod slides along the wave surface of the wave-shaped guide plate, thereby driving the plug plate to perform horizontal reciprocating motion inside the piston cylinder. A return spring is fixedly connected between the stopper plate and the inner wall of the piston cylinder. Check valves are fixedly connected to both the upper and lower sides of the piston cylinder. An air supply pipe is fixedly connected between the inside of the top check valve and the sleeve. An air inlet pipe is fixedly connected to the outside of the bottom check valve. The connection between the air supply pipe and the sleeve is located above the initial position of the piston ring.

[0010] Preferably, when the piston ring is displaced to the connection between the pressure relief pipe and the sleeve, the air pressure inside the sleeve above the piston ring is relieved through the pressure relief pipe, thereby causing the tension spring to drive the piston ring to reset, causing the wedge sleeve to release the ball top rod, thus achieving cyclic protection when the multiple layers of the bearing plates are stacked from bottom to top.

[0011] Preferably, the top material mechanism includes a fixed frame fixedly connected to the bottom of the base frame and an electric telescopic cylinder fixedly installed at the bottom of the fixed frame. A top plate is fixedly connected to the output end of the electric telescopic cylinder. The top plate is located at the bottom of the bearing plate and is used to lift the bearing plate upward. When the bearing plate rises, it drives the guide structure to cooperate with the transmission structure, thereby transmitting the lifting power of the top material mechanism to the transmission structure.

[0012] Preferably, there are four sets of support legs, which are fixedly connected to the bottom of the base frame in a rectangular shape. There are also four sets of limiting frames, which are fixedly connected to the top of the base frame in a rectangular shape. Multiple sets of bearing plates are slidably connected to the inside of the limiting frames, and the inside of the limiting frames is provided with a conveying port for conveying the bearing plates.

[0013] Preferably, the base frame is provided with a limiting mechanism on its exterior for supporting and limiting the bottom of the lowest bearing plate. The limiting mechanism is located between adjacent limiting frames. The limiting mechanism includes a first hinge seat and a fixed seat fixedly connected to the exterior of the base frame. An electric push rod is hingedly installed inside the first hinge seat. A blocking block is rotatably connected inside the fixed seat. A second hinge seat is fixedly connected to the output end of the electric push rod. The second hinge seat and the blocking block are rotatably connected.

[0014] Preferably, the angle of the blocking block around the fixed seat is adjusted by extending and retracting the output end of the electric push rod, thereby supporting or moving the carrier plate for transport. When the electric push rod drives the blocking block to rotate to the supporting position, the blocking block limits the bottom of the bearing plate. When the electric push rod drives the blocking block to rotate to the yielding position, the bearing plate can be conveyed along the conveying port.

[0015] In summary, the present invention has the following beneficial effects: 1. In this invention, after the insert rod of the guide structure is inserted into the insert sleeve, the piston ring inside the sleeve of the displacement structure is driven to move downward by air pressure, which drives the displacement sleeve and the wedge sleeve to move downward. The wedge surface of the wedge sleeve pushes the ball top rod and the abutment plate to move radially inward and press against the insert rod, thereby maintaining the horizontal interlayer position of the bearing disk, preventing the bearing disk from shifting when the stacked storage is frequently started and stopped, and improving the positioning accuracy and operational safety of multi-layer stacking.

[0016] 2. In this invention, the sleeve is fixed to the inner wall of the limiting frame by a wave-shaped guide plate. When the sleeve rises with the bearing plate, the reciprocating rod slides along the wave surface, driving the plug plate to move horizontally back and forth in the piston cylinder. Air is supplied to the sleeve through the check valve and the air supply pipe, driving the piston ring to move downward. The lifting power of the top material mechanism is automatically converted into radial locking force, reducing the risk of interlayer slippage and misalignment caused by start-stop inertia.

[0017] 3. In this invention, when the piston ring moves down to the point where the pressure relief pipe connects with the sleeve, the air pressure above the piston ring in the sleeve is relieved through the pressure relief pipe. The tension spring drives the piston ring to reset, the wedge sleeve loosens the ball top rod, and the compressed spring resets the ball top rod. Thus, when the multi-layer bearing plates are stacked from bottom to top, automatic unlocking and cyclic protection are implemented to avoid overload damage and improve the reliability of continuous operation of the equipment.

[0018] 4. In this invention, the top plate is driven by an electric telescopic cylinder to lift multiple sets of bearing plates upward in sequence. The bearing plates drive the inserts and sleeves to rise. The sleeves drive the reciprocating rod of the transmission structure to slide along the wave-shaped guide plate. At the same time, the insert rod of the guide structure is inserted into the upper insert, so that the lifting, guiding and locking are completed simultaneously, ensuring the continuity of multi-layer stacking and improving storage and transportation efficiency.

[0019] 5. In this invention, when the electric push rod of the limiting mechanism drives the blocking block to rotate to the supporting position, it forms a limit on the bottom of the lowest bearing plate; at the same time, the insertion rod of the guide structure connects with the insertion sleeve, and the piston ring of the displacement structure is driven to move down by the air pressure of the transmission structure, which drives the wedge sleeve to lock the ball top rod, thereby realizing the linkage locking of the interlayer positioning when the bearing plates are stacked and stored, and improving the operational safety.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example: Please refer to Figures 1 to 7 The diagram illustrates a multi-layer stacking storage and conveying rack for gas detector injection molded parts. It includes a storage and conveying rack body 1, a top-feeding mechanism 2 disposed inside the storage and conveying rack body 1, and a limiting mechanism 3. The storage and conveying rack body 1 includes a base frame 11, support legs 12, a limiting frame 13, and a conveying port 14. Multiple carrier trays 4 are disposed inside the storage and conveying rack body 1, and the gas detector injection molded part body 5 is placed inside the carrier trays 4. A guide structure 6 for maintaining horizontal inter-layer position is disposed outside the carrier trays 4. The rack also includes a displacement structure 7 and a transmission structure 8. The displacement structure 7 is disposed outside a sleeve 63 and is used to drive a ball joint rod 64 to extend or retract radially along the sleeve 63, so that an abutment plate 65 abuts against or releases the ball joint rod 61. An input device for conveying the carrier trays 4 to the surface of the top-feeding mechanism 2 is disposed outside the storage and conveying rack body 1.

[0025] The lifting mechanism 2 lifts the carrier plate 4 upwards, and the carrier plate 4 drives the guide structure 6 to dock with the upper carrier plate 4. The displacement structure 7, driven by the transmission structure 8, radially locks the guide structure 6, realizing multi-layer stacking storage. With the linkage of the guide structure 6, the displacement structure 7 and the transmission structure 8, the horizontal inter-layer position of the carrier plate 4 is maintained, preventing the carrier plate 4 from shifting when the stacking storage is frequently started and stopped, thus improving the positioning accuracy and operational safety of multi-layer stacking.

[0026] Specifically, the top material mechanism 2 includes a fixed frame 21 fixedly connected to the bottom of the base frame 11 and an electric telescopic cylinder 22 fixedly installed at the bottom of the fixed frame 21. A top plate 23 is fixedly connected to the output end of the electric telescopic cylinder 22. The top plate 23 is located at the bottom of the bearing plate 4 and is used to lift the bearing plate 4 upward. When the bearing plate 4 rises, it drives the guide structure 6 to cooperate with the transmission structure 8, thereby transmitting the lifting power of the top material mechanism 2 to the transmission structure 8.

[0027] It should be noted that there are four sets of support legs 12, which are fixedly connected to the bottom of the base frame 11 in a rectangular shape. There are also four sets of limiting frames 13, which are fixedly connected to the top of the base frame 11 in a rectangular shape. Multiple sets of bearing plates 4 are slidably connected inside the limiting frames 13. The limiting frames 13 have conveying ports 14 for conveying the bearing plates 4. The four sets of support legs 12 are fixedly fixed to the bottom of the base frame 11 in a rectangular shape to form a stable support. The four sets of limiting frames 13 are fixedly fixed to the top of the base frame 11 in a rectangular shape to form a multi-layer storage space. The bearing plates 4 slide along the inside of the limiting frames 13 and are input through the conveying ports 14.

[0028] To achieve stable stacking and conveying of multiple-layer carrier trays, please refer to... Figure 1 , Figures 4 to 7 In one embodiment of this invention, the guide structure 6 includes a rod 61 fixedly connected to the top of the support plate 4 and a sleeve 63 fitted over the rod 61. A buffer airbag ring 62 is fixedly connected to the top of the rod 61. A ball-top rod 64 slides through the inside of the sleeve 63, and an abutment plate 65 is fixedly connected to one end of the ball-top rod 64, located outside the rod 61. When two adjacent support plates 4 are stacked, the rod 61 of the lower support plate 4 inserts into the sleeve 63 of the upper support plate 4. The buffer airbag ring 62 undergoes elastic deformation to reduce the mating gap. The ball-top rod 64 and the abutment plate 65 radially lock the rod 61 under the drive of the displacement structure 7. Through the mating cooperation between the rod 61 and the sleeve 63, rapid positioning and guidance of adjacent support plates 4 are achieved, the buffer airbag ring 62 buffers pressure, and stacking accuracy and stability are improved.

[0029] Specifically, the insertion rod 61 is fixedly connected to the top of the carrier plate 4, and the insertion sleeve 63 is fixedly connected to the bottom of the carrier plate 4. This is used to guide the docking and cooperation when two adjacent sets of carrier plates 4 are stacked and stored. The insertion rod 61 at the top of the lower carrier plate 4 is inserted into the insertion sleeve 63 at the bottom of the upper carrier plate 4 to guide the docking and cooperation of two adjacent sets of carrier plates 4.

[0030] It should be noted that the abutment plate 65 is arc-shaped, and a compression spring 66 is fixedly connected between the end of the ball top rod 64 away from the abutment plate 65 and the outer wall of the insert 63. The compression spring 66 is sleeved on the outside of the ball top rod 64. When the displacement structure 7 releases the ball top rod 64, the compression spring 66 pushes the ball top rod 64 and the abutment plate 65 to return to their original position outward, releasing the lock on the insert 61. When the displacement structure 7 pushes the ball top rod 64 inward, the abutment plate 65 overcomes the elastic force of the compression spring 66 and presses against the insert 61, improving the reliability of the lock and the efficiency of the release.

[0031] To achieve inter-layer follow-up locking and avoid stacking offset issues, please refer to... Figure 1 , Figures 4 to 7 As one embodiment of this example, the displacement structure 7 includes a sleeve 71 fixedly connected to the outside of the insert 63 and a piston ring 72 slidably connected to the inside of the sleeve 71. A tension spring 73 is fixedly connected between the top of the piston ring 72 and the inner top wall of the sleeve 71. A displacement sleeve 74 penetrating the sleeve 71 is fixedly connected to the bottom of the piston ring 72. A wedge-shaped sleeve 75 is fixedly connected to the bottom of the displacement sleeve 74. A wedge-shaped surface is provided inside the wedge-shaped sleeve 75. The wedge-shaped sleeve 75 is located outside the ball top rod 64. A sealing gasket adapted to the displacement sleeve 74 is fixedly connected inside the sleeve 71. The piston ring 72, the displacement sleeve 74, and the wedge-shaped sleeve 75 are all slidably connected to the outside of the insert 63. When air pressure enters the space above piston ring 72 inside sleeve 71, it pushes piston ring 72 to move downward against the tension of tension spring 73. Piston ring 72 drives displacement sleeve 74 and wedge sleeve 75 downward. The wedge surface of wedge sleeve 75 pushes ball top rod 64 and abutment plate 65 to move radially inward to abut insertion rod 61, thereby maintaining the horizontal interlayer position of bearing plate 4 and preventing bearing plate 4 from shifting during frequent start-stop.

[0032] Specifically, a pressure relief pipe 76 is fixedly connected to the outside of the sleeve 71, and the piston ring 72 is initially positioned above the pressure relief pipe 76. With the piston ring 72 initially positioned above the pressure relief pipe 76, a sealed pressure chamber is formed above the piston ring 72 inside the sleeve 71. When the piston ring 72 moves down to the connection point of the pressure relief pipe 76, the pressure is discharged through the pressure relief pipe 76, achieving automatic limiting of the downward stroke of the piston ring 72 and pressure release. The structure is simple and reliable.

[0033] It should be noted that when the piston ring 72 moves downward under the transmission structure 8, the piston ring 72 drives the displacement sleeve 74 and the wedge sleeve 75 to move downward. The wedge sleeve 75 drives the ball top rod 64 and the abutment plate 65 to move into the insert sleeve 63, thereby achieving external limiting of the insert rod 61 by the abutment plate 65. The piston ring 72 moves downward under the pneumatic drive of the transmission structure 8, driving the displacement sleeve 74 and the wedge sleeve 75 downward. The wedge-shaped surface of the wedge sleeve 75 pushes the ball top rod 64 and the abutment plate 65 into the insert sleeve 63. The abutment plate 65 presses against the insert rod 61 to achieve radial limiting, thereby maintaining the horizontal interlayer position of the bearing plate 4 and improving the positioning accuracy of multi-layer stacking.

[0034] It is worth mentioning that when the piston ring 72 moves to the connection between the pressure relief pipe 76 and the sleeve 71, the air pressure inside the sleeve 71 above the piston ring 72 is released through the pressure relief pipe 76, thereby causing the tension spring 73 to drive the piston ring 72 to reset, and causing the wedge sleeve 75 to release the ball top rod 64, realizing cyclic protection when the multi-layer bearing plates 4 are stacked from bottom to top. When the piston ring 72 moves down to the connection between the pressure relief pipe 76 and the sleeve 71, the air pressure above the piston ring 72 is released through the pressure relief pipe 76, the tension spring 73 drives the piston ring 72 to reset and move upward, the wedge sleeve 75 releases the ball top rod 64, and the compression spring 66 resets the ball top rod 64 and the abutment plate 65, realizing automatic unlocking and cyclic protection when the multi-layer bearing plates 4 are stacked from bottom to top, avoiding the abutment plate 65 from seizing the insertion rod 61, and improving the reliability of continuous operation of the equipment.

[0035] To achieve the effect of linkage locking between lifting power and pneumatic pressure, please refer to... Figure 1 , Figures 4 to 7 In one embodiment of this invention, the transmission structure 8 is disposed outside the displacement structure 7 and is used to convert the lifting power of the top material mechanism 2 into the radial driving force of the displacement structure 7. The transmission structure 8 includes a corrugated guide plate 81 fixedly connected to the inner wall of the limiting frame 13 and a piston cylinder 82 fixedly connected to the outside of the sleeve 71. A stop plate 83 is slidably connected inside the piston cylinder 82, and a reciprocating rod 84 is fixedly connected to the outside of the stop plate 83, penetrating the piston cylinder 82. The end of the reciprocating rod 84 away from the stop plate 83 slides against the corrugated surface of the corrugated guide plate 81.

[0036] Specifically, when the sleeve 71 rises with the insert sleeve 63 and the bearing plate 4, the reciprocating rod 84 slides along the wave surface of the wave-shaped guide plate 81, thereby driving the plug plate 83 to perform horizontal reciprocating motion inside the piston cylinder 82; by the sleeve 71 rising with the insert sleeve 63 and the bearing plate 4, and the reciprocating rod 84 sliding along the wave surface of the wave-shaped guide plate 81, the plug plate 83 is driven to perform horizontal reciprocating motion inside the piston cylinder 82, thus realizing the pumping and air-pressing actions.

[0037] It should be noted that a return spring 85 is fixedly connected between the inner wall of the stopper plate 83 and the piston cylinder 82. Check valves 86 are fixedly connected to both the upper and lower sides of the piston cylinder 82. An air supply pipe 88 is fixedly connected between the inside of the top check valve 86 and the sleeve 71, and an air inlet pipe 87 is fixedly connected to the outside of the bottom check valve 86. The connection between the air supply pipe 88 and the sleeve 71 is located above the initial position of the piston ring 72. When the stopper plate 83 reciprocates horizontally, the return spring 85 assists the stopper plate 83 in resetting. Outside air enters the piston cylinder 82 through the air inlet pipe 87 and the bottom check valve 86, while compressed air enters the space above the piston ring 72 inside the sleeve 71 through the top check valve 86 and the air supply pipe 88, driving the piston ring 72 to move downwards. Through the unidirectional conduction of the check valve 86 and the assisted resetting of the return spring 85, continuous air supply drives the displacement structure 7, ensuring stable and reliable locking action.

[0038] To achieve vertical protection and transport clearance adaptation for the bearing plate 4, please refer to... Figures 1 to 4 In one embodiment of this invention, a limiting mechanism 3 is provided on the outside of the base frame 11 to support and limit the bottom of the lowest bearing plate 4. The limiting mechanism 3 is located between adjacent limiting frames 13. The limiting mechanism 3 includes a first hinge seat 31 and a fixed seat 33 fixedly connected to the outside of the base frame 11. An electric push rod 32 is hingedly installed inside the first hinge seat 31. A blocking block 34 is rotatably connected inside the fixed seat 33. A second hinge seat 35 is fixedly connected to the output end of the electric push rod 32. The second hinge seat 35 and the blocking block 34 are rotatably connected. By extending or retracting the output end of the electric push rod 32, the second hinge seat 35 drives the blocking block 34 to rotate around the fixed seat 33, thereby adjusting the angle of the blocking block 34.

[0039] Specifically, the angle of the blocking block 34 around the fixed base 33 is adjusted by extending and retracting the output end of the electric push rod 32, thereby supporting or allowing the carrier plate 4 to be conveyed. When the electric push rod 32 drives the blocking block 34 to rotate to the supporting position, the blocking block 34 limits the bottom of the carrier plate 4. When the electric push rod 32 drives the blocking block 34 to rotate to the yielding position, the carrier plate 4 can be conveyed along the conveying port 14. When the electric push rod 32 drives the blocking block 34 to rotate to the supporting position, the blocking block 34 limits the bottom of the lowest carrier plate 4 to prevent it from falling. When the electric push rod 32 drives the blocking block 34 to rotate to the yielding position, the carrier plates 4 are stacked upwards along the conveying port 14 for storage.

[0040] Working principle of the invention: During the standby and loading stages of the equipment, the limiting mechanism 3 provides vertical safety protection. The electric push rod 32 installed on the first hinge seat 31 on the outside of the base frame 11 drives the blocking block 34 to rotate to the support position through the second hinge seat 35, providing bottom support and limiting for the bottom support plate 4, preventing the support plate 4 from falling and shaking when the equipment starts and stops. When entering the stacking mode, the electric push rod 32 drives the blocking block 34 to switch to the yielding position, releasing the vertical limit, so that the support plate 4 can be smoothly lifted and displaced upwards, providing structural conditions for continuous cyclic stacking and storage. After the gas detector injection molded part body 5 is placed into the carrier plate 4, the carrier plate 4 is transported to the inside of the limiting frame 13 through the input device outside the storage and conveying frame 1; the top material mechanism 2 is started, and the electric telescopic cylinder 22 drives the top plate 23 to lift the bottom carrier plate 4 upward. The carrier plate 4 slides and rises along the inside of the limiting frame 13, and at the same time, it drives the bottom insert 63 and sleeve 71 to rise synchronously and enter the stacking station. When the carrier plate 4 rises to below the upper carrier plate 4, the insertion rod 61 at the top of the lower carrier plate 4 is inserted into the insertion sleeve 63 at the bottom of the upper carrier plate 4. The buffer airbag ring 62 at the top of the insertion rod 61 undergoes elastic deformation, reducing the fitting gap between the insertion rod 61 and the insertion sleeve 63, realizing the rapid docking and guiding of the two adjacent sets of carrier plates 4, ensuring the stacking alignment accuracy, and preventing the carrier plate 4 from shifting horizontally. As the sleeve 71 rises with the insert 63 and the bearing plate 4, the reciprocating rod 84 of the transmission structure 8 slides along the wave surface of the wave-shaped guide plate 81 on the inner wall of the limiting frame 13. Since the wave-shaped guide plate 81 extends a long distance along the height direction of the limiting frame 13, the reciprocating rod 84 will pass through the wave surface multiple times during the displacement of the bearing plate 4 from bottom to top, causing the plug plate 83 to make horizontal reciprocating motion inside the piston cylinder 82. Outside air enters the piston cylinder 82 through the air inlet pipe 87 and the bottom check valve 86, and compressed air enters the space above the piston ring 72 inside the sleeve 71 through the top check valve 86 and the air delivery pipe 88, realizing the cyclic conversion of lifting power to pneumatic power. Pneumatic pressure pushes piston ring 72 to move downward against the tension of spring 73. Piston ring 72 drives displacement sleeve 74 and wedge sleeve 75 downward. The wedge surface of wedge sleeve 75 pushes ball top rod 64 and abutment plate 65 to move radially inward into insert sleeve 63. Abutment plate 65 presses against insert rod 61, thereby maintaining the horizontal interlayer position of bearing disk 4, preventing bearing disk 4 from shifting when stacked storage is frequently started and stopped, and improving the positioning accuracy of multi-layer stacking. When the piston ring 72 is pushed down by the air pressure accumulated inside the sleeve 71 to the point where the pressure relief pipe 76 connects with the sleeve 71, the air pressure above the piston ring 72 inside the sleeve 71 is released through the pressure relief pipe 76. The tension spring 73 drives the piston ring 72 to reset and move upward. The wedge sleeve 75 releases the ball top rod 64, and the compression spring 66 causes the ball top rod 64 and the abutment plate 65 to reset outward, releasing the lock on the insertion rod 61. Since the wave-shaped guide plate 81 extends a long distance along the height direction of the limit frame 13, the bearing plate 4 will cycle through the above locking and unlocking process during the displacement from bottom to top, realizing automatic unlocking and cyclic protection when the multi-layer bearing plates 4 are stacked from bottom to top, avoiding overload damage. When the electric push rod 32 of the limiting mechanism 3 drives the blocking block 34 to rotate around the fixed base 33 to the supporting position, the blocking block 34 forms a limit on the bottom of the lowest bearing plate 4 to prevent it from falling. When output is required, the electric push rod 32 drives the blocking block 34 to rotate to the yielding position, and the bearing plate 4 is output along the conveying port 14 of the limiting frame 13, realizing the linkage locking of horizontal interlayer positioning and improving operational safety.
