Description

(1) Technical field

[0002] The invention belongs to the technical field of packaging carton processing, and in particular relates to a carton precision forming mechanism. (2) Background Technology

[0004] Packaging cartons are extremely widely used in the field of cargo packaging and transportation. The processing of packaging cartons requires processes such as die-cutting, waste removal, and gluing. After the cardboard is die-cut and waste removed, it needs to be glued together. During the gluing and gluing process, uneven bonding is prone to occur, resulting in uneven die-cuts on both sides of the gluing mouth, with one side having a wide die-cut and the other side having a narrow die-cut. This causes the gluing cardboard to tilt, seriously affecting the quality of the cardboard. After the adhesive dries, the folded cardboard tilts, causing the carton to have quality problems such as misalignment. Our company's patent, application number 2023216008347, announcement date 2023.11.28, titled "A Precision Carton Forming Device," uses a support plate cylinder to drive two support plates to open, so as to support the two die-cuts of the gluing mouth to the same width. This adds an extra process and is inefficient. (III) Summary of the Invention

(V) Specific implementation methods

[0029] The accompanying drawings illustrate a specific embodiment of the present invention. This embodiment comprises a conveyor belt 1 mounted on a frame. A front baffle 2, which can be raised and lowered, is located above the front of the conveyor belt 1. A push plate 3, located above the rear of the conveyor belt 1, is located above the rear of the conveyor belt 1. A liftable pressure plate 4, located between the front baffle 2 and the push plate 3, is provided. A support block 5, which can pass through the pressure plate 4, is provided on the pressure plate 4. A suction cup 6 is mounted on the end of the pressure plate 4. The suction cup 6 is mounted on the bottom of a suction cup cylinder 7, which is fixed to the pressure plate 4.

[0030] The top of the pressure plate 4 is mounted on the output end of the pressure plate cylinder 8. The support block 5 is mounted below the support block mounting base 9. The support block mounting base 9 is mounted on the support block mounting base slider 10. The support block mounting base slider 10 is mounted on the side of the pressure plate cylinder 8 and is fixed to the top of the pressure plate 4. An adjusting bolt 11 is installed on the top of the support block mounting base slider 10. A screw 12 is mounted on the side of the support block mounting base slider 10. Two stoppers 13 are mounted on the screw 12 and located on both sides of the support block 5. The two stoppers 13 are fixed to the screw 12 by nuts 14, allowing the support block 5 to move along the support block mounting base 9.

[0031] The front baffle 2 is fixed to the output end of the front baffle cylinder 16 through the front baffle fixing plate 15, and the front baffle cylinder 16 is installed on the front baffle slider 17. A limit rod 18 is installed on the front baffle fixing plate 15.

[0032] The push plate 3 is hinged to the bottom of the swing cylinder 20 via the swing arm 19. The top of the swing cylinder 20 is clamped on the front and rear slide rails 22 via the swing cylinder slider 21. The swing cylinder slider 21 is fixed to the front and rear slide rails 22 via the swing cylinder slider locking bolts 23. The top of the pressure plate cylinder 8 is clamped on the front and rear slide rails 22 via the pressure plate cylinder slider 24. The pressure plate cylinder slider 24 is fixed to the front and rear slide rails 22 via the pressure plate cylinder slider locking bolts 25.

[0033] A compression belt 26 is provided on the outside of the conveyor belt 1. A sponge block 27 is provided on the lower surface of the pressing plate 4.

[0034] With the carton precision forming mechanism of the present invention, cardboard 28, which has undergone die-cutting, waste removal, and gluing, is placed on the conveyor belt 1. Both sides of the cardboard 28 are pressed against the conveyor belt 1 by the compression belts 26. As the conveyor belt 1 and the compression belt 26 rotate, the cardboard 28 is driven forward. When the cardboard 28 moves below the front baffle 2, the front baffle cylinder 16 is activated to drive the front baffle fixing plate 15 downward, thereby driving the front baffle 2 to move down above the conveyor belt 1 to block the front end of the cardboard 28. The swing cylinder 20 is activated, and its piston rod moves downward. The front end of the piston rod of the swing cylinder 20 is a rack, which drives the gear to rotate during the downward movement. The gear rotation drives the swing arm 19 to rotate, thereby driving the push plate 3 to rotate above the conveyor belt 1. During the rotation of the push plate 3, the cardboard 28 is pushed forward and aligned, and together with the front baffle 2, the cardboard 28 is clamped. The suction cup cylinder 7 is activated, driving the suction cup 6 downward until it adheres to the cardboard 28. The suction cup cylinder 7 then moves the suction cup 6 upward a short distance, raising the upper portion of the cardboard 28 upward. This allows the support block 5 to extend into the two die cuts 29, thus stretching the two inclined die cuts 29 to equal widths, making the bonded edges flush with the outer edges of the cardboard 28. The bonded edges are not completely bonded, so there is no damage to the cardboard 28. The two pressure plate cylinders 8 are activated, driving the pressure plate 4 downward to press on the top of the cardboard 28. The pressure plate 4 moves downward through the support block mounting block slider 10, driving the support block mounting block 9 and the support block 5 downward. Simultaneously, the suction cup 6 releases the cardboard 28, flattening it. Finally, as the pressure plate 4 presses down onto the cardboard 28, the two ends of the bonded edges of the cardboard 28 are flush. The support block 5 passes through the long hole in the pressure plate 4 and extends into the die cuts 29 of the cardboard 28, completing the spreading action. After the expansion is complete, the pressure plate 4 and support block 5 move upward. Simultaneously, the push plate 3 rotates upward, the front baffle 2 moves upward, and the conveyor belt 1 and the pressure belt 26 continue to rotate, feeding the cardboard 28 to the next process. The support block mounting block slider 10 moves along the guide rail on the surface of the pressure plate cylinder 6. The downward movement of the support block mounting block slider 10 drives the adjustment bolt 11 downward. The adjustment bolt 11 can be used to adjust the length of the support block 5 extending into the die cut 29. The front baffle slider 17 is fixed to the frame and can move left and right along the frame to adjust the left and right position of the front baffle 2, thereby adapting to the needs of different cardboards 29. When the front baffle 2 moves upward, the limit rod 18 prevents the front baffle fixing plate 15 from rebounding excessively. The swing cylinder slider 21 can move back and forth along the front and rear slide rails 22, thereby adjusting the front and rear position of the push plate 3 and the distance between the push plate 3 and the front baffle 2 to accommodate cardboards 28 of different widths. Similarly, the two pressing plate cylinder sliders 24 can also move forward and backward along the front and rear slide rails 22, thereby adjusting the front and rear positions of the two pressing plates 4 and the two support blocks 5 so that they are just above the two die cuts 29 of the cardboard 28.A slider is mounted on top of the support block 5, which slides along a track below the support block mounting seat 9, thereby enabling the support block 5 to move laterally along the support block mounting seat 9. After loosening the two nuts 14 and allowing the two stoppers 13 to drive the support block 5 to the desired lateral position, the two nuts 14 can be tightened. This allows the support block 5 to change in the lateral position of the die-cut 29 of the cardboard 28. When the pressure plate 4 moves downward to press the cardboard 28, a sponge block 27 is provided below the pressure plate 4. The sponge block 27 positions the cardboard 29 without pressing too tightly and protects the surface of the cardboard 28 from being scratched, thereby allowing the support block 5 to smoothly and quickly complete the opening of the die-cut 29.
