The two steel wires 228 pass through the corresponding limiting rollers, support rollers and inner rollers and are then fixed on the moving plate 25.

[0024] A sliding groove 229 is formed in the top of the mounting plate 21. The blanking piece comprises a sliding seat 230 slidably arranged inside the sliding groove 229 and a toothed strip 234 fixed on the inner wall of the groove 23. A reduction motor 235 is fixed on the top of the sliding seat 230. A gear 236 is fixed on one end of the output shaft of the reduction motor 235. The gear 236 is engaged with the toothed strip 234. A side hinged pushing arm 237 is fixed on the sliding seat 230. The side hinged pushing arm 237 can be regarded as a fixed arm rod and two hinged arms hinged on both sides of one end of the arm rod. When moving towards the moving plate 25, the two hinged arms will not be deflected. When moving in the opposite direction, the two hinged arms will be deflected due to the obstruction of the object.

[0025] The bottom of the moving plate 25 is provided with two insertion slots 247, and the mounting plate 21 is provided with two symmetrical inner cavities 238, and the inner sides of the two inner cavities 238 are provided with connecting grooves 239, one end of the connecting groove 239 is communicated with the slot body 23, the positioning member is provided with two, and the two positioning members are respectively arranged in the two inner cavities 238 and the two connecting grooves 239, the positioning member comprises an inclined column 246 sliding on the inner side of the inner cavity 238, the inclined surface of the inclined column 246 faces the direction of the moving plate 25, the inclined column 246 is provided with an inclined groove two 240, and the one end of the inclined column 246 and the inner cavity 238 are fixedly connected with a limiting spring 241, when the limiting spring 241 is at the original length, the one end of the inclined column 246 is above the mounting plate 21, the positioning member further comprises a pushing rod 242 sliding on the inner side of the connecting groove 239 and an inclined rod 243 fixed on the inner side of the connecting groove 239, when the limiting spring 241 is at the original length, one end of the pushing rod 242 faces the downward end of the opening of the inclined groove two 240, one end of the pushing rod 242 is fixedly connected with a groove rod 244, and the groove rod 244 is slidingly connected with a plate body 245, and the plate body 245 slides on the inclined rod 243.

[0026] In use: when the box containing dangerous chemicals is pushed to the mounting plate 21, the box pushes the moving plate 25 to move, and the moving plate 25 drives the gravity strip 26 to slide along the inclined sliding rod 24 to the higher end through the connecting plate 28, until the box moves the moving plate 25 to the position of the inclined column 246, and the inclined column 246 is extruded into the inner cavity 238 and extrudes the limiting spring 241, then under the reaction force of the limiting spring 241, the one end of the inclined column 246 is pushed into the corresponding insertion slot 247 at the bottom of the moving plate 25 to fix the position of the moving plate 25, at the same time, when the moving plate 25 moves, under the change of the position of the steel wire rope 228, the hollow rod 225 moves downward, until the pressing plate 226 presses on the top of the box to assist in limiting the box, if the pressing plate 226 still moves after contacting the top of the box, the pressing plate 226 and the hollow rod 225 will not be displaced under the limitation of the box, but the gravity plate 227 will slide downward in the hollow rod 225 and continue to pull the steel wire rope 228, so that the steel wire rope 228 always maintains a taut state, avoiding the relaxation of the steel wire rope 228 affecting the operation of other structures.

[0027] The moving plate 25 moves to the position of the connecting arm 224 when it is pushed by the box, and the connecting arm 224 moves with the driving of the driving plate 232, and the C-shaped frame 222 slides along the slide rail 220 with the driving of the connecting arm 224, so that the penetrating rod 223 slides in the inclined hollow plate 221, and the inclined hollow plate 221 and the sliding box 210 move upward, and the sliding box 210 moves upward with the limiting plate 211, and the limiting plate 211 blocked by the bottom of the box cannot move to the top of the mounting plate 21, so that the relative sliding of the sliding box 210 and the limiting plate 211 is generated and the reset spring 212 is pressed, and the limiting plate 211 not covered by the box is pushed to the top of the mounting plate 21, and one of the limiting plates 211 corresponding to the size of the box is tightly attached to the edge of the box to block the box; If the four-sided inclined limiting strip 218 in the limiting plate 211 tightly attached to the edge of the box is located at one side of the box, it will not move out of the moving box 215, and the four-sided inclined limiting strip 218 in the limiting plate 211 close to the corner of the edge of the box will be pushed out of the moving box 215 by the reset of the inner spring 217, and the inclined surface close to the corners of the two sides of the box will press the small spring 219 under the pushing of the box, so that the four-sided inclined limiting strip 218 and the other four-sided inclined limiting strips 218 located at the two sides of the box slide a little to the two sides of the box respectively, so that the four-sided inclined limiting strip 218 can be clamped at the two sides of the box, and the automatic stabilization of the box of various sizes can be realized.

[0028] After the box is stabilized, it is sent to the stacking position under the moving of the moving frame 1, and then the deceleration motor 235 is started to drive the gear 236 to rotate, and the gear 236 drives the sliding seat 230 to slide along the sliding groove 229 under the meshing of the toothed strip 234, and the sliding seat 230 drives the side hinged pushing arm 237 to move, and the side hinged pushing arm 237 first contacts and pushes the two plate bodies 245, and the two plate bodies 245 slide downward on the inclined rod 243 when being pushed, and slide downward in the slot rod 244 and drive the pushing rod 242 to move through the slot rod 244, and the pushing rod 242 translates in the connecting slot 239 and enters the inclined slot two 240, so as to drive the inclined column 246 downward to be separated from the insertion slot 247 to release the limiting of the moving plate 25, and the plate body 245 slides downward along the inclined rod 243 to reduce the position and will not hinder the movement of the side hinged pushing arm 237, and the inclined column 246, the pushing rod 242 and the plate body 245 are reset after the moving plate 25 is pushed away from the position of the inclined column 246; When the side hinged push arm 237 moves as described above, its one end will be inserted into the inclined slot 233 on the push plate 232 through the slot of the hollow plate 231, and the push plate 232 will move upward under the continuous insertion, and the push plate 232 will enter the hollow plate 231 and no longer be at the same height as the associated arm 224, so that the limit of the associated arm 224 is released. After the limit of the associated arm 224 is released, the sliding box 210 will slide downward under its own gravity, thereby driving the limit plate 211 to move to the position where the top surface of the mounting plate 21 is flat. At this time, the limit in front of the box is released, and under the continuous operation of the reduction motor 235, the side hinged push arm 237 will push the moving plate 25 to move, and the moving plate 25 will push the box to the stacking position. At the same time, after the box moves away from the mounting plate 21, the moving plate 25 will always remain in the original state without the box being pushed to the position on the mounting plate 21 under the gravity of the gravity strip 26 and the inclined guide of the inclined slide rod 24. Then the reduction motor 235 reverses to the original position away from the moving plate 25, and when the side hinged push arm 237 passes through the plate body 245, the two hinged arms will be deflected by the plate body 245, so that the side hinged push arm 237 will not be hindered when it is reset.
