Since the foam temporary storage box 3 and the foam box need to be the same size to ensure that the foam box is in the same position in the foam temporary storage box 3 every time, a high degree of alignment is required to put the foam box into the foam temporary storage box 3, and at the same time, under the action of the arc surface, the foam box can gradually enter the center position of the foam temporary storage box 3, so that the foam box can be easily put into the foam temporary storage box 3 and be located in the same position in the foam temporary storage box 3 every time.

[0029] refer to Figures 2 to 4 The foam box placement platform is located at the shorter end, and a conveyor belt groove is provided on the other side of the mounting base 1. A conveyor belt 5 is provided in the conveyor belt groove. The conveyor belt 5 is externally connected. A coating is placed on the conveyor belt 5, and the conveyor belt 5 faces the foam box placement platform. A mounting groove located at the lower end of the foam placement platform 2 is provided on the mounting base 1. The mounting groove is located between the conveyor belt 5 and the foam placement platform 2. A driving mechanism that reciprocates in the mounting groove is provided in the mounting groove. A first cylinder 10 is vertically fixedly connected to the driving structure, and a bearing platform 9 is fixedly connected to the top of the first cylinder 10. The size of the bearing platform 9 is larger than the through groove at the lower end of the foam temporary storage box 3. At the same time, the bearing platform 9 is shaped like a convex block with a center The raised part is matched with the through groove at the lower end of the foam temporary storage box 3, and the driving mechanism drives the supporting platform 9 to reciprocate between the lower end of the foam box placement platform and the conveyor belt 5; a cutting mechanism is installed on the mounting base 1 located on one side of the conveyor belt 5, and the film is cut by the cutting mechanism. After cutting, the film will fall onto the supporting platform 9, and a U-shaped cavity is opened at the upper end of the supporting platform 9. A U-shaped rubber block 13 is slidably connected in the U-shaped cavity. The U-shaped rubber block 13 and the U-shaped cavity are connected by a plurality of evenly distributed springs. The U-shaped rubber block 13 and the U-shaped groove face the conveyor belt 5. Through the cooperation of the spring and the U-shaped rubber block 13, a buffering effect is provided when the supporting platform 9 contacts the bottom surface of the foam temporary storage box 3.

[0030] The cutting mechanism includes a second cylinder 8 horizontally fixedly connected to the mounting base 1, the output end of the second cylinder 8 is fixedly connected to the mounting base 6, the lower end of the mounting base 6 is threadedly connected to a slitting knife 14, the cutting edge of the slitting knife 14 faces the conveyor belt 5, and there are two guard plates 7 fixedly connected to the mounting base 6 close to one end of the conveyor belt 5, the two guard plates 7 are respectively located on both sides of the conveyor belt 5, and the two guard plates 7 are slidably connected to the mounting base 1, and reinforcing ribs are also provided on the upper ends of the guard plates 7 and the mounting base 6 to improve the connection stability. The slitting knife 14 can cut off the film as the second cylinder 8 moves, and the guard plates 7 can limit the cut film and guide the cut film to fall onto the carrier plate.

[0031] The driving structure includes a threaded rod 11 rotatably connected in the mounting groove, and a bidirectional motor 4 for driving the threaded rod 11 is fixedly connected to the mounting base 1, the output end of the bidirectional motor 4 passes through the mounting base 1 and is rotatably connected to the threaded rod 11, a connecting block 12 is slidably connected in the mounting groove, T-shaped sliders are provided at both ends of the connecting block 12, a sliding groove adapted to the T-shaped slider is provided in the mounting groove, the connecting block 12 is slidably connected in the mounting groove through the T-shaped slider and the sliding groove, the connecting block 12 is threadedly connected to the threaded rod 11, and the top of the connecting block 12 is fixedly connected to the base of the first cylinder 10. Since the connecting block 12 is limited by the T-shaped slider, the connecting block 12 can only move along the direction of the sliding groove, and the connecting block 12 is threadedly connected to the threaded rod 11, and when the driving motor rotates, it drives the threaded rod 11 to rotate, and the rotation of the threaded rod 11 causes the connecting block 12 to move along the direction of the sliding groove.

[0032] The cutting mechanism, the driving mechanism, the conveyor belt 5 and the first cylinder 10 are all controlled and coordinated by the PLC electronic control system. The cutting mechanism peels the coating off onto the supporting platform 9 through the cutting knife. The supporting platform 9 is moved to the lower end of the foam placement platform 2 through the driving mechanism. The coating is squeezed to the bottom end of the foam temporary storage box 3 through the first cylinder 10, thereby improving the service life of the foam box, improving the pressure-bearing capacity and load-bearing capacity of the foam box, and making the foam box more stable and reliable when in use.

[0033] Working principle: when laminating and pasting the bottom of the foam box, the foam box is placed in the foam temporary storage box 3, and the second cylinder 8 drives the cutting knife to cut the film. After cutting, the second cylinder 8 is retracted to prevent obstruction of the conveyor belt 5 to drive the movement of the film. After the cutting is completed, the conveyor belt 5 moves, driving the subsequent film to move and supplement to the vacant position after the lack. The cut film falls onto the carrier due to the movement of the belt. While the conveyor belt 5 moves, the bidirectional motor 4 drives the threaded rod 11 to rotate, thereby driving the carrier 9 to move to the bottom of the foam temporary storage box 3. After the film is pasted to the bottom end of the foam box by the first cylinder 10, the first cylinder 10 is reset, and the bidirectional motor 4 reverses to return the first cylinder 10 to the lower end of the conveyor belt 5. Repeat the above process to realize the reciprocating work of pasting the film on the bottom of the foam box.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
