Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a packaging machine cutting device. Background Technology

[0002] Packaging machines are a type of equipment used for food packaging and product packaging. Some packaging machines first package the entire product and then cut it into pieces. For example, in the packaging of circuit boards, multiple circuit boards are first encapsulated in bubble wrap, and then the packaged bubble wrap is cut into pieces. During the cutting process, both horizontal and vertical cuts are required. Therefore, a long operating table is set at the rear of the packaging machine to cut the products, which causes the packaging machine to occupy a large part of the production area. Utility Model Content

[0003] The technical problem this utility model aims to solve is to address the shortcomings of the existing technology by providing a packaging machine cutting device. To solve the above technical problem, the technical solution adopted by this utility model is:

[0004] A packaging machine slitting device includes a worktable. Rodless cylinders are mounted on both sides of the worktable, and sliders are mounted on the rodless cylinders. A gantry support connects the sliders. A second rodless cylinder is mounted on the side of the gantry support, and sliders are mounted on the second rodless cylinder. A cylinder mounting plate is mounted on the slider, and a cylinder is mounted on the cylinder mounting plate. A tool holder plate is connected to the piston end of the cylinder. A mounting hole is machined on one side of the tool holder plate, and a bearing is installed in the mounting hole. A rotating shaft passes between the bearings. A gear is mounted on the upper end of the rotating shaft, and a blade is mounted on the lower end of the rotating shaft. A motor bracket is mounted on the side of the rotating shaft, and a motor is mounted on the motor bracket. A gear is connected to the output shaft of the motor, and gears mesh with each other.

[0005] Furthermore, a guide groove is machined on the upper side of the rotating shaft, a support is provided on the tool holder plate, a threaded hole is machined on the support, a corrugated screw is connected in the threaded hole, the steel ball of the corrugated screw is inserted into the guide groove, positioning holes are machined at both ends of the guide groove, and an arc-shaped transition section is provided between the positioning hole and the guide groove.

[0006] Furthermore, the worktable is a negative pressure worktable.

[0007] Furthermore, the cylinder is a dual-axis guided cylinder.

[0008] Furthermore, the lower end of the rotating shaft is machined with a mounting groove, into which the blade is inserted, and the blade is locked in place by screws on the side of the mounting groove.

[0009] Compared with the prior art, the packaging machine slitting device of this utility model can achieve both vertical and horizontal slitting on the same workbench by driving the blades on the rotating shaft with a motor, thus shortening the length of the equipment and making the equipment structure simpler.

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0015] like Figures 1-3 As shown, a packaging machine slitting device includes a worktable 1. Rodless cylinders 2 are mounted on both sides of the worktable 1. A slider 1 is mounted on each rodless cylinder 2. A gantry support 3 connects the sliders 1. A rodless cylinder 4 is mounted on the side of the gantry support 3. A slider 2 is mounted on the slider 4. A cylinder fixing plate is mounted on the slider 2. A cylinder 5 is mounted on the cylinder fixing plate. A tool support plate 6 is connected to the piston end of the cylinder 5. A mounting hole (stepped hole) is machined on one side of the tool support plate 6. Bearings 7 are mounted at both ends of the mounting hole. A rotating shaft 8 passes between the bearings 7. A gear 9 is mounted on the upper end of the rotating shaft 8 via a key block. A blade 10 is mounted on the lower end of the rotating shaft 8. A mounting groove is machined on the lower end of the rotating shaft 8, into which the blade 10 is inserted. The blade 10 is locked in place by screws on the side of the mounting groove. A motor support is mounted on the side of the rotating shaft 8. A motor 11 is mounted on the motor support. A gear 2 is connected to the output shaft of the motor 11. Gear 1 and gear 2 mesh.

[0016] In this embodiment, the workbench 1 is a negative pressure workbench. The negative pressure on the surface of the negative pressure workbench adsorbs the packaging bag when cutting and packaging products. The piston end of the cylinder 5 extends and retracts to control the downward movement of the blade 10. In this embodiment, the cylinder 5 is a dual-axis guide cylinder. Then, the rodless cylinder 2 and the rodless cylinder 4 work to achieve longitudinal cutting. Then, the motor 11 drives the rotating shaft 8 to rotate, so that the blade rotates.

[0017] A guide groove 12 is machined on the upper side of the rotating shaft 8. A support is provided on the tool holder plate 6, and a threaded hole is machined on the support. A corrugated screw 13 is connected in the threaded hole. The steel ball of the corrugated screw 13 is inserted into the guide groove 12. In this embodiment, the length of the guide groove 12 is one-quarter of the circumference of the rotating shaft 8. Positioning holes 14 are machined at both ends of the guide groove 12. When the steel ball of the corrugated screw 13 is inserted into different positioning holes 14, the blade 10 on the rotating shaft 8 rotates 90°. Then, it works through rodless cylinder 2 and rodless cylinder 4 to achieve cross-cutting.

[0018] An arc-shaped transition section 15 is provided between the positioning hole 14 and the guide groove 12. By providing the arc-shaped transition section 15, the steel ball at the end of the wave screw 13 can easily disengage from the positioning hole 14 when the motor 11 is driven.

[0019] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
