Description

Technical Field

[0001] This utility model relates to the field of packaging carton production technology, specifically a cutting device for producing fruit packaging cartons. Background Technology

[0002] Fruit packaging cartons are typically made of sturdy materials to protect the fruit from damage during transportation and storage. Common fruit packaging cartons primarily use corrugated cardboard. The corrugated cardboard is cut to specified dimensions, then folded and assembled into boxes or other packaging forms as needed, with the edges secured with glue, tape, or staples. After cutting, the corrugated cardboard is scattered throughout the work area, increasing the risk of damage from being squeezed or bumped by other objects, especially at the edges and corners, which are prone to curling or tearing, affecting subsequent packaging processes. Furthermore, the varying sizes of the packaging cartons and the inflexible stacking methods for different sizes during the collection process after cutting can lead to mutual compression of the cardboard, potentially causing edge damage, deformation, or even breakage, affecting subsequent use and product quality. To address these issues, the inventor proposes a cutting device for fruit packaging carton production. Utility Model Content

[0003] To address the issues of centralized stacking of cut cardboard and stacking of cardboard of different specifications, the purpose of this utility model is to provide a cutting device for the production of fruit packaging cartons.

[0035] The base 1 has two symmetrically distributed grooves 703, and the slider 702 slides in the grooves 703.

[0036] By adopting the above technical solution, the movable frame 701 moves under the guidance of the slider 702 and the slide groove 703.

[0037] Guide blocks 405 are fixedly provided on both sides of the lifting tool holder 401. Guide frames 406 are slidably provided on the outer wall of the guide blocks 405, and the guide frames 406 are fixedly installed on the inner wall of the top frame 3.

[0038] By adopting the above technical solution, the lifting tool holder 401 can move up and down under the guidance of the guide block 405 and the guide frame 406.

[0039] The cutting workbench 2 is equipped with a baffle 8 that works in conjunction with the palletizing positioning component 7 on the side near the palletizing spacing adjustment component 6.

[0040] By adopting the above technical solution, the baffle 8 can be slidably inserted into the cutting workbench 2.

[0041] Working principle: First, the corrugated cardboard needed for fruit packaging cartons is placed on the cutting worktable 2. An external feeding device pushes the cardboard forward at equal intervals. Each forward movement of the cardboard causes the control motor 407 to drive the crankshaft 403 to rotate one revolution. During rotation, the crankshaft 403, through the connecting rod 404 and the lifting blade holder 401, drives the cutting blade 402 to move up and down once under the guidance of the guide block 405 and the guide frame 406. The lifting blade holder 401, moving up and down once, works in conjunction with the cutting worktable 2 to cut the corrugated cardboard. The cut cardboard falls to the top of the base 1 under the limit of the baffle 8. Then, the first electric cylinder 506 and the second electric cylinder 704 are activated. Figure 5 As shown, the drive end of the first electric cylinder 506 pushes the right palletizing plate 501 to move. During the movement, the right palletizing plate 501 drives the left palletizing plate 501 to move synchronously in the opposite direction under the action of the drive rod 505 and the rotating plate 504. Under the action of the guide ring 507 and the guide rod 508, the two palletizing plates 501 move closer to each other, so that the two adjusting plates 603 are in contact with the two ends of the corrugated cardboard, thus aligning the corrugated cardboard laterally. The drive end of the second electric cylinder 704 extends and pushes the moving frame 701 to move under the guidance of the slider 702 and the slide groove 703. The movement of the moving frame 701 pushes the aligned corrugated cardboard to move towards the baffle 8, so that the ends of the corrugated cardboard are in contact with the baffle 8. After contacting and aligning, when it is necessary to remove the stacked corrugated cardboard, simply pull the baffle 8 out of the cutting table 2. If it is necessary to adjust the stacking spacing, simply turn the handle 606 manually. The rotation of the handle 606 drives the lead screw 601 to rotate. Under the action of the screw ring 602, the lead screw 601 pushes the adjusting plate 603 to move under the guidance of the guide post 604 and stretches the spring 605. The tension of the spring 605 on the adjusting plate 603 is much smaller than the torque between the lead screw 601 and the screw ring 602. The spring 605 only plays a buffering role during the movement and does not affect the adjusting plate 603. The stacking spacing can be adjusted by adjusting the position of the two adjusting plates 603.

[0042] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
