Description

Technical Field

[0001] The utility model relates to the technical field of carton production and cutting, in particular to a cutting device for carton production. Background Art

[0002] Cartons are packaging containers made of cardboard, which are widely used in the packaging and protection of goods. They have good cushioning, stiffness, impact resistance and pressure bearing, etc., covering almost all areas of goods that need packaging and protection. In the production process of cartons, cutting is a very important link. Generally, the cutting knife cuts the corresponding shape along the cutting line on the cardboard. However, when the number of cardboards to be cut is large, the cardboard is easy to move during the cutting process, resulting in differences in the cut shapes and low cutting accuracy. In addition, the existing cutting machine uses a sharper knife for cutting. The pressure is concentrated on the edge of the blade during cutting, resulting in excessive pressure at the edge of the blade, which will produce cutting burrs and easily generate dust.

[0025] The cutting operation is performed by the set workbench 1, the cardboard with cutting is stacked in the stacking area, and the stacked cardboard is cut in the cutting area. The cardboard is fixed by the set fixing device to prevent movement during cutting that affects the cutting accuracy. The side baffle limits the cardboard around, the pressing plate 11 fixes the cardboard from the top, and the hydraulic cylinder 14 can adjust the height of the pressing plate 11. The cardboard is cut by the set cutting device, and the moving device drives the ultrasonic cutting knife 22 to move and cut the cardboard. The bottom of the cardboard is supported by the set template 15, and the through hole opened on the template 15 is convenient for the ultrasonic cutting knife 22 to cut the cardboard

[0026] In some feasible embodiments, a handle 4 is provided on the left side wall of the push plate 3 to facilitate pushing and pulling the push plate 3 .

[0027] In some feasible embodiments, the side baffle includes a first baffle 5 and two second baffles 6, the first baffle 5 is fixedly arranged on the workbench 1, the two second baffles 6 are movably arranged at the two ends of the left side of the first baffle 5, and the second baffle 6 is controlled to move by a driving device, the driving device includes a bidirectional threaded rod 7, a mounting plate 8, two first sliders 9 and a motor 10, the mounting plate 8 and the motor 10 are fixedly arranged on the right side of the first baffle 5, one end of the bidirectional threaded rod 7 is rotatably connected to the mounting plate 8, the other end of the bidirectional threaded rod 7 is fixedly connected to the output end of the motor 10, the two first sliders 9 are sleeved at both ends of the bidirectional threaded rod 7, the first slider 9 is fixedly connected to the right end of the second baffle 6 through a connecting rod, and a slide groove for the connecting rod to move is provided on the first baffle 5. The motor 10 drives the bidirectional threaded rod 7 to rotate, driving the first slider 9 to move, because the first slider 9 is limited by the connecting rod, so that the first slider 9 does not rotate with the bidirectional threaded rod 7, and the two first sliders 9 move inward or outward at the same time with the rotation of the bidirectional threaded rod 7, thereby driving the two second baffles 6 to move, so as to adjust the distance between the two second baffles 6.

[0028] In some feasible embodiments, a pressure sensor 12 is embedded at the bottom of the pressing plate 11. The pressure sensor 12 records the pressure applied by the pressing plate 11 to the cardboard. When the pressure reaches a preset value, the pressing plate 11 is controlled to stop moving downward, so that the pressing plate 11 can fix the pile of cardboards, and the applied pressure is not enough to damage the cardboard.

[0029] In some feasible embodiments, the moving device includes a first electric guide rail 18, a second electric guide rail 19, a second slider 20 and a telescopic rod 21.

The first electric guide rail 18 and the second electric guide rail 19 work together, so that the ultrasonic cutting knife 22 can move freely to cut the cardboard.

[0030] When in use, the worker stacks the cardboards to be cut neatly in the stacking area. After stacking, the push plate 3 is pushed so that the push plate 3 drives the pile of cardboards into the cutting area. The push plate 3 moves to the right until the right side of the cardboard contacts the first baffle 5. Then the motor 10 is controlled to move the two second baffles 6 toward the middle at the same time until they contact the cardboard. Subsequently, the hydraulic cylinder 14 is controlled to drive the pressing plate 11 to move downward until the pressure sensor 12 detects that the pressure reaches the preset value. At this time, the pile of cardboards is fixed. Finally, the cutting device is started to make the ultrasonic cutting knife 22 cut the cardboard.
