Description

Technical Field

[0001] This utility model relates to the technical field of flatbed die-cutting machines, specifically to a semi-automatic flatbed die-cutting machine for cartons. Background Technology

[0002] Paper box die-cutting machines are post-press processing equipment used in the paper packaging and decoration industry. They are mainly used for die-cutting, creasing, and cold embossing of materials such as trademarks, paper boxes, and greeting cards. Their core function is to apply pressure using steel blades, steel wires, or templates to cut and shape cardboard, create markings, and imprint three-dimensional patterns. Flatbed die-cutting machines use a flat structure and come in vertical and horizontal types: vertical machines have a simpler structure but lower efficiency and are suitable for small-batch production, while horizontal machines are equipped with an automatic paper feeding system, offering higher safety and automation.

[0003] Chinese patent CN222698012U discloses a semi-automatic flatbed die-cutting machine for cardboard boxes. Specifically, it is a vertical flatbed die-cutting machine. The process involves placing the cardboard to be die-cut on a placement table. After placement, pulling the clamping plate upwards causes it to pull the connecting rod. The limiting plate at the bottom of the connecting rod moves upwards against the spring force. At this point, pushing the L-shaped block positions the clamping plate at the cardboard's clamping position. Releasing the clamping plate, under the spring force, allows it to hold the cardboard. Simultaneously, a hydraulic cylinder extends, pushing the die-cutting blade to move, thus die-cutting the cardboard. When bevel die-cutting is required, the drive motor operates, driving the drive gear to rotate. The drive gear, in turn, drives the driven gear, which in turn rotates the shaft and placement table. This rotation of the placement table moves the cardboard to the desired bevel die-cutting position, making it highly versatile.

[0004] In the above scheme, although the cardboard is die-cut using a die-cutting blade, the debris generated during the die-cutting process easily adheres to the blade edge, thus affecting the subsequent use of the die-cutting blade and reducing the die-cutting quality of the cardboard.

[0005] Therefore, this utility model provides a semi-automatic flatbed die-cutting machine for cardboard boxes to solve the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a semi-automatic flatbed die-cutting machine for cardboard boxes, which solves the problem that debris generated during the die-cutting process easily adheres to the blade of the die-cutting knife, thereby affecting the subsequent use of the die-cutting knife and reducing the die-cutting quality of the cardboard.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A semi-automatic flatbed die-cutting machine for cardboard boxes includes: A workbench is provided with a movable groove, and a placement seat is slidably connected in the movable groove. A paper placement template is installed on the placement seat.

[0008] The push component, located on the worktable, is used to switch the paper feeding template from the feeding position to the die-cutting position.

[0009] A bracket is installed on a workbench. A second hydraulic cylinder is mounted on the bracket. A lifting plate is fixedly connected to the telescopic end of the second hydraulic cylinder. An air jet seat and a die-cutting tool are mounted on the lifting plate. The air jet seat is connected to an external air pump, and the discharge end of the air jet seat is located at the die-cutting part of the die-cutting tool.

[0010] Preferably, the bottom surface of the workbench is fixedly connected to a support leg, and a collection box is placed under the workbench, with the collection box located below the die-cutting tool.

[0011] Preferably, the pushing component includes a first hydraulic cylinder mounted on the workbench, the telescopic end of the first hydraulic cylinder being fixedly connected to the placement seat.

[0012] Preferably, the inner wall of the moving groove is provided with a guide groove, and guide blocks are fixedly connected to both sides of the placement seat, and the guide blocks are slidably connected in the guide groove.

[0013] Preferably, the support includes a top plate, on which two sets of fixing rods are fixedly connected, and the bottom ends of the fixing rods are fixedly connected to the worktable. The second hydraulic cylinder is installed on the top plate, and the lifting plate is slidably connected to the fixing rods.

[0014] Preferably, the die-cutting part of the die-cutting tool has an opening, and the air jet seat is connected to the opening.

[0015] Preferably, the placement seat has a feeding groove and an installation groove, and the feeding groove and the installation groove are connected, and the paper placement template is installed in the installation groove.

[0016] Preferably, the workbench is provided with two sets of limiting blocks, each of which is equipped with a connecting bolt, and the limiting blocks are mounted on the placement seat by the connecting bolt.

[0017] The beneficial effects of this utility model are as follows: 1. By simultaneously setting the air jet seat and the die-cutting blade on the lifting plate, and connecting the openings at the air jet seat and the cutting edge of the die-cutting blade, and connecting the air jet seat to an external air pump, after the die-cutting operation is completed, high-pressure gas can be delivered through the air jet seat to the opening of the cutting edge of the die-cutting blade and sprayed out, directly blowing away the debris adhering to the cutting edge. This avoids problems such as blade blockage and reduced die-cutting accuracy caused by debris residue. It not only ensures the consistency and pass rate of cardboard die-cutting, but also reduces the blade wear caused by debris wear, and extends the service life of the die-cutting blade.

[0018] 2. By providing a feeding slot connected to the mounting slot in the placement seat, and placing a collection box under the worktable corresponding to the die-cutting position, the die-cutting debris can fall directly into the collection box through the feeding slot, avoiding debris accumulation on the worktable surface or in the gaps of the equipment. This maintains a clean working environment and facilitates the unified recycling and processing of debris. The first hydraulic cylinder in the pushing component can directly drive the placement seat to slide in the moving slot, eliminating the need for manual handling or adjustment of the placement seat position. This reduces manual operation steps and improves the turnover efficiency of a single die-cutting operation, making it particularly suitable for batch processing needs in semi-automatic production scenarios.

[0024] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0025] A semi-automatic flatbed die-cutting machine for cardboard boxes includes a worktable 1, a pushing component, and a support.

[0026] The workbench 1 is provided with a moving groove 4, and a placement seat 6 is slidably connected in the moving groove 4. A paper placement template 10 is installed on the placement seat 6.

[0027] The placement seat 6 can move inside the moving groove 4, so that the placement seat 6 has two work positions on the worktable 1, namely the feeding position and the die-cutting position. When the carton is die-cut, the carton needs to be placed on the paper feeding template 10.

[0028] In this embodiment, the placement seat 6 is provided with a feeding groove 8 and an installation groove 9, and the feeding groove 8 and the installation groove 9 are connected. The paper template 10 is installed in the installation groove 9.

[0029] The paper placement template 10 can be fixed in the mounting slot 9 with bolts. When the carton placed on the paper placement template 10 is finished with die cutting, the resulting debris will fall through the feeding slot 8 and fall below the worktable 1.

[0030] The push component is set on the workbench 1 and is used to switch the paper feeding template 10 from the feeding position to the die-cutting position by the placement seat 6.

[0031] In this embodiment, the pushing component includes a first hydraulic cylinder 15 mounted on the workbench 1, and the telescopic end of the first hydraulic cylinder 15 is fixedly connected to the placement seat 6.

[0032] The position of the placement seat 6 is switched by moving the placement seat 6 inside the moving groove 4 through the extension and retraction end of the first hydraulic cylinder 15.

[0033] To improve the stability of the placement seat 6 during the die-cutting process, a guide groove 5 is provided on the inner wall of the moving groove 4, and guide blocks 7 are fixedly connected to both sides of the placement seat 6, and the guide blocks 7 are slidably connected in the guide groove 5.

[0034] When the placement seat 6 moves within the moving groove 4, it causes the guide block 7 to slide inside the guide groove 5. The impact force generated during the die-cutting of the carton on the placement seat 6 is distributed to the worktable 1 through the guide block 7 and the guide groove 5.

[0035] The extension end of the second hydraulic cylinder 16 is fixedly connected to a lifting plate 17. The lifting plate 17 is equipped with an air jet seat 18 and a die-cutting cutter 19. The air jet seat 18 is connected to an external air pump, and the discharge end of the air jet seat 18 is located at the die-cutting part of the die-cutting cutter 19. The die-cutting part of the die-cutting cutter 19 has an opening, and the air jet seat 18 is connected to the opening.

[0036] The jet seat 18 can be adaptively adjusted according to the number of die-cutting parts on the die-cutting cutter 19. That is, a single jet seat 18 is aligned with a single die-cutting part, and adjacent jet seats 18 can be connected through air pipes. The die-cutting part of the die-cutting cutter 19 is a cutting edge. The die-cutting part on the die-cutting cutter 19 is inserted into the through groove on the paper feeding template 10 to complete the die-cutting of the paperboard. After the die-cutting is completed, the air pump delivers high-pressure gas to the jet seat 18 and sprays it out through the opening of the die-cutting part, thereby blowing the debris off the die-cutting part and preventing the debris from sticking to the die-cutting part.

[0037] The bracket is installed on the workbench 1, and a second hydraulic cylinder 16 is installed on the bracket. The bracket includes a top plate 13, and two sets of fixing rods 14 are fixedly connected to the top plate 13. The bottom end of the fixing rods 14 is fixedly connected to the workbench 1. The second hydraulic cylinder 16 is installed on the top plate 13, and the lifting plate 17 is slidably connected to the fixing rods 14.

[0038] The bottom surface of the workbench 1 is fixedly connected to the support leg 2. A collection box 3 is placed under the workbench 1, and the collection box 3 is located below the die-cutting cutter 19. The collection box 3 is used to collect the debris generated by die-cutting.

[0039] Two sets of limiting blocks 11 are provided on the workbench 1. Each of the two limiting blocks 11 is equipped with a connecting bolt 12, and the limiting blocks 11 are installed on the placement seat 6 through the connecting bolt 12. The limiting blocks 11 are L-shaped, and the corners of the four limiting blocks 11 can form a rectangular structure. The four sides of the carton are placed inside the rectangular structure, and the edges of the carton are attached to the limiting blocks 11, which can position the carton board to be die-cut.
