Description

Technical Field

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

[0002] Crease notch cutting is an important process in carton production. It is used to pre-create predetermined bending points and notches on the cardboard to facilitate subsequent folding and forming. The existing carton production crease notch cutting usually places the cardboard directly on the cutting machine for cutting, and then moves the cardboard by the rollers on the cutting machine. However, the cutting machine may cause the cardboard to deviate when cutting, thereby affecting the quality of carton production and being relatively inconvenient.

[0003] Therefore, it is necessary to design a crease notch cutting device for carton production that can flatten and limit the cardboard to avoid deviation and bending of the cardboard during cutting, thereby improving the quality of carton production. Utility Model Content

[0004] In order to overcome the disadvantages of the existing crease notch cutting for carton production, in which the cutting machine may cause the cardboard to deflect when cutting the cardboard, thereby affecting the quality of carton production, which is relatively inconvenient, the utility model provides a crease notch cutting device for carton production that can flatten and limit the cardboard, avoid the cardboard from deflecting and bending when cutting, and improve the quality of carton production.

[0005] The technical solution is: a crease notch cutting device for carton production, including a base plate, a support frame, an extension plate, a cylinder, a cutter and a connecting piece. The upper rear side of the base plate is connected to the support frame, the front of the support frame is slidably connected to the extension plate, the lower side of the extension plate is connected to the cylinder, the cutter is sleeved on the telescopic end of the cylinder, and the upper part of the cutter is threadedly connected to the connecting piece.

[0006] Furthermore, it also includes a bolt, the front upper part of the support frame is threadedly connected with the bolt, and the bolt is in contact with the extension plate.

[0007] Furthermore, a knob is provided on the bolt.

[0008] Furthermore, it also includes a push plate and a first spring. The push plate is slidably connected to the cutter, and the first spring is connected between the left and right parts of the push plate and the cutter.

[0009] Furthermore, it also includes a baffle and a connecting rod. The rear part of the bottom plate is slidably connected to the left and right connecting rods, and the baffle is connected between the front sides of the connecting rods.

[0010] Furthermore, it also includes a fixing frame, a pressure plate and a second spring. The left and right sides of the bottom plate are connected to the front and rear fixing frames, and the pressure plates are slidably connected between the two adjacent fixing frames. The second spring is connected between the fixing frames and the adjacent pressure plates.

[0011] Beneficial effects: 1. The utility model places the cardboard on the bottom plate and slides it into the lower side of the pressure plate, so that the cardboard moves upward, the second spring is squeezed and contracted, and then pushes the connecting rod, driving the connecting rod to move forward, so that the baffle contacts the cardboard, and the cardboard is flattened and limited by the pressure plate and the baffle, thereby achieving the effect of flattening and limiting the cardboard, avoiding deviation and bending of the cardboard during cutting, and improving the quality of carton production.

[0012] 2. The utility model achieves the effect of being able to replace the cutter by putting different cutters on the telescopic end of the cylinder, docking the connecting piece with the cutter, and then rotating the connecting piece so that the connecting piece moves under the action of the thread, thereby fixing the cutter on the telescopic end of the cylinder, thereby adapting to different usage needs, being convenient to use, reducing equipment maintenance costs, and improving the flexibility of using the device.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0017] A crease notch cutting device for carton production, such as Figure 1 and Figure 2As shown, it includes a base plate 1, a support frame 2, an extension plate 3, a bolt 4, a cylinder 5, a cutter 6, a connecting piece 7, a push plate 8, a first spring 9, a baffle 10, a connecting rod 11, a fixing frame 12, a pressure plate 13 and a second spring 14. The upper rear side of the base plate 1 is connected to the support frame 2, the front of the support frame 2 is slidably connected to the extension plate 3, the upper front part of the support frame 2 is threadedly connected to the bolt 4, the bolt 4 is in contact with the extension plate 3, and a knob is provided on the bolt 4 for easy rotation. The lower side of the extension plate 3 is connected to the cylinder 5, and the telescopic end of the cylinder 5 A cutter 6 is sleeved on the top, a connector 7 is threadedly connected to the upper part of the cutter 6, a push plate 8 is slidably connected to the cutter 6, and a first spring 9 is connected between the left and right parts of the push plate 8 and the cutter 6, the rear part of the bottom plate 1 is slidably connected to the left and right connecting rods 11, a baffle 10 is connected between the front sides of the connecting rods 11, and the left and right sides of the bottom plate 1 are connected to the front and rear fixing frames 12, and a pressure plate 13 is slidably connected between the two adjacent fixing frames 12, and a second spring 14 is connected between the fixing frames 12 and the adjacent pressure plates 13.

[0018] When using this device, first place the bottom plate 1 on the crease notch cutting area for carton production, then place the cardboard on the bottom plate 1 and scratch it into the lower side of the pressure plate 13, so that the cardboard moves upward, the second spring 14 is squeezed and contracted, and then pushes the connecting rod 11, driving the connecting rod 11 to move forward, so that the baffle 10 contacts the cardboard, and the cardboard is flattened and limited by the pressure plate 13 and the baffle 10, so that the cardboard can be flattened and limited, avoiding the cardboard from deflecting and bending during cutting, thereby improving the quality of carton production, and then the knob can be turned to drive the bolt 4 to rotate, so that the bolt 4 moves upward under the action of the thread, so that the bolt 4 no longer contacts the extension plate 3, and then the extension plate 3 is adjusted to align the cutter 6 with the position to be cut, and then the cylinder 5 is started to drive the cutter 6 to move downward. The cutter 6 contacts the cardboard, so that the cut waste contacts the push plate 8, which moves upward, and the first spring 9 is squeezed and contracted. When the cutter 6 moves upward, the first spring 9 is restored, so that the push plate 8 moves and resets, so that the waste is pushed down. When different notches need to be cut, the connecting piece 7 can be rotated so that the connecting piece 7 moves under the action of the thread, so that the connecting piece 7 is separated from the cutter 6, and then a different cutter 6 is put on the telescopic end of the cylinder 5, and then the connecting piece 7 is connected to the cutter 6. Then the connecting piece 7 is rotated so that the connecting piece 7 moves under the action of the thread, and then the cutter 6 is fixed on the telescopic end of the cylinder 5, so that the cutter 6 can be replaced, which is convenient to adapt to different usage needs, easy to use, reduces equipment maintenance costs, and improves the flexibility of using the device.
