[0034] With reference to Figure 2 and Figure 5 The driving assembly 5 comprises a driving rod 51, a limiting plate 52 and a sliding rod 53. The driving rod 51 is vertically arranged and in the shape of a rectangular rod, and is slidingly connected with the moving plate 423 in the vertical direction. A limiting slot 511 is formed in the driving rod 51, and the limiting slot 511 is a rectangular slot. A limiting clamping block 5111 is horizontally arranged in the limiting slot 511, and the limiting clamping block 5111 is in the shape of a rectangular block and is slidingly connected with the driving rod 51 in the length direction of the conveying belt 11.

[0037] When the moving plate 423 moves downward, the fourth spring 512 is in a compressed state. The moving plate 423 drives the driving rod 51 to move downward synchronously. After the driving rod 51 abuts against the blanking plate 22, the driving rod 51 extrudes the blanking plate 22, and the blanking plate 22 rotates. When the moving plate 423 moves to the mounting frame 2, the sliding rod 53 abuts against the mounting frame 2. The mounting frame 2 is extruded by the sliding rod 53. Under the action of the continuous downward pushing force of the moving plate 423, the sliding rod 53 slides along the horizontal direction towards the limiting block 5111. The sliding rod 53 extrudes the limiting block 5111. The limiting block 5111 slides into the limiting groove 511. The third spring 5112 is in a compressed state. The fourth spring 512 resets. The fourth spring 512 drives the limiting plate 52 to slide upward. The limiting plate 52 drives the driving rod 51 to slide synchronously. The bottom end of the driving rod 51 is separated from the blanking plate 22. The bottom surface of the pressing plate 424 completely contacts the surface of the fast food box and applies a uniform downward pressure, so that the pressing plate 424 easily stacks and compacts the fast food boxes entering the collecting box 3.

One side of the air bag 62 is flush with the side wall of the discharge port 21. The air bag 62 is hollow inside and filled with a liquid. The first connecting pipe 63 has a circular pipe shape and is fixedly communicated with the air bag 62 and the rodless cavity of the adjusting telescopic rod 61 at two ends. The first connecting pipe 63 is provided with a first one-way valve 631.

[0040] When the sliding rod 53 slides along the horizontal direction to the limiting block 5111, the distance between the first connecting plate 4231 and the second connecting plate 531 changes, so that the fifth spring 5311 is in a compressed state. When the moving plate 423 continues to move downward, the sliding rod 53 moves to the bottom of the mounting frame 2, the fifth spring 5311 is reset, the fifth spring 5311 pushes the sliding rod 53 to slide away from the limiting block 5111, the sliding rod 53 extrudes the air bag 62, the liquid in the air bag 62 is extruded and flows into the rod cavity of the adjusting telescopic rod 61 through the first one-way valve 631 in a one-way manner, the adjusting telescopic rod 61 is driven to stretch to lift the mounting height of the pressing telescopic rod 422. When the sliding rod 53 is disconnected with the air bag 62, the air bag 62 is reset, the liquid in the rod cavity of the limiting telescopic rod 71 flows into the air bag 62 in a one-way manner through the second one-way valve 721, and the movable end of the limiting telescopic rod 71 is retracted. When the lunch boxes in the collecting box 3 are stacked to a set height, the air bag 62 is extruded for many times, the liquid in the rod cavity of the limiting telescopic rod 71 gradually decreases, so that the movable end of the limiting telescopic rod 71 is retracted, the movable end of the limiting telescopic rod 71 is disconnected with the limiting hole 311, and the locking of the box door 31 is released. The box door 31 slides to close the collecting box 3 under the action of the second spring 251. When the collecting box 3 is replaced, the controller 24 controls the hydraulic pump 731 to work, the liquid in the rod cavity of the adjusting telescopic rod 61 flows into the rod cavity of the limiting telescopic rod 71 through the third connecting pipe 73, and the automatic locking of the box door 31 after the collecting box 3 is fully loaded and the reset of the limiting telescopic rod 71 after the empty box is replaced are realized.

[0041] The implementation principle of the plastic fast food box forming equipment in the embodiment of the application is as follows: After the collecting box 3 is mounted to the mounting frame 2, the operator slides the box door 31 to open the collecting box 3, the box door 31 extrudes the driving plate 25, the second spring 251 is in a compressed state, the controller 24 controls the hydraulic pump 731 to work, the liquid in the rod cavity of the adjusting telescopic rod 61 flows into the rod cavity of the limiting telescopic rod 71 through the third connecting pipe 73, and the movable end of the limiting telescopic rod 71 slides into the limiting hole 311.

[0042] When the shaped plastic fast food box is conveyed to the preset position by the conveying belt 11, the controller 24 controls the movable end of the pushing telescopic rod 411 to drive the pushing plate 412 to push the fast food box on the conveying belt 11 to the position of the discharge port 21; the pressing telescopic rod 422 is lowered synchronously under the instruction of the controller 24, and the fast food box falling into the collecting box 3 is applied with vertical pressure by the pressing plate 424.

[0043] During the lowering of the moving plate 423, the fourth spring 512 is in the compressed state, the moving plate 423 drives the driving rod 51 to be pressed synchronously, the driving rod 51 extrudes the lower plate 22, the lower plate 22 rotates, when the moving plate 423 moves to the position of the mounting frame 2, the sliding rod 53 abuts against the mounting frame 2, the mounting frame 2 and the sliding rod 53 are extruded, the sliding rod 53 slides along the horizontal direction towards the limiting block 5111, the fifth spring 5311 is in the compressed state, the sliding rod 53 extrudes the limiting block 5111, the limiting block 5111 slides into the limiting slot 511, the fourth spring 512 resets, and the fourth spring 512 drives the limiting plate 52 to slide upwards, the bottom end of the driving rod 51 is separated from the lower plate 22.

[0044] When the moving plate 423 continues to move downwards, the sliding rod 53 moves to the bottom of the mounting frame 2, the fifth spring 5311 resets, the fifth spring 5311 pushes the sliding rod 53 to extrude the air bag 62, the liquid in the air bag 62 flows into the rodless cavity of the adjusting telescopic rod 61, the adjusting telescopic rod 61 is driven to extend to lift the mounting height of the pressing telescopic rod 422. When the sliding rod 53 is separated from the air bag 62, the air bag 62 resets, the liquid in the rodless cavity of the limiting telescopic rod 71 flows into the air bag 62, the movable end of the limiting telescopic rod 71 retracts, when the fast food boxes in the collecting box 3 are stacked to the set height, the air bag 62 is extruded for many times, the liquid in the rodless cavity of the limiting telescopic rod 71 gradually decreases, the movable end of the limiting telescopic rod 71 is separated from the limiting hole 311, the locking of the box door 31 is released, the box door 31 slides to close the collecting box 3 under the action of the second spring 251, thereby completing the whole-process collecting operation of the fast food boxes.

[0045] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
