Description

Technical Field

[0001] The utility model relates to a cardboard slitting mechanism. Background Art

[0002] A cardboard slitter is a device for slitting cardboard (it can also be called a grooving machine, the difference lies in whether it cuts through, so in terms of structure, it can be exactly the same as a cardboard grooving machine, just with a different name). The cardboard slitter includes a paper feeding device (a flying paper feeding device or other paper feeding devices), a cardboard conveying device, and a cardboard slitting device. The paper feeding device sends the cardboard to the cardboard conveying device, and the cardboard conveying device then sends the cardboard to the cardboard slitting device for slitting. The cardboard slitting device generally includes a cutter, a roller, a belt, and multiple tension rollers. The belt is wound around multiple tension rollers, and under the action of multiple tension rollers, the belt is partially pressed on the roller. The cardboard is conveyed over by the cardboard conveying mechanism and then enters between the belt and the roller. In this way, the cardboard is bent and attached to the roller under the action of the belt. The roller rotates driven by a power source, driving the cardboard and the belt to rotate together. The cutter is located on the side where the roller and the belt are attached. As the cardboard moves, the cutter slits (or grooves) the cardboard. However, some cardboard has poor quality and the cardboard pieces may stick together. When the paper feeding device feeds the paper, it may send multiple overlapping cardboard pieces to the cardboard conveying device, and the cardboard conveying device will send the overlapping cardboard pieces to the cardboard slitting device for slitting, which will cause problems in subsequent slitting: for example, the cardboard below cannot be slit, and even when it reaches the slitting knife, it may get stuck, resulting in the need to readjust the slitting knife, which is very inconvenient. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the utility model innovatively provides a cardboard slitter for preventing overlapping conveyance of cardboard.

[0004] This cardboard slitter for preventing overlapping conveyance of cardboard includes a paper feeding device and a cardboard conveying device, and is characterized in that: a cardboard separating mechanism and a cardboard overlapping detection mechanism are provided above the cardboard conveying device. The cardboard overlapping detection mechanism includes a photoelectric eye, and the cardboard separating mechanism includes a separating member for separating the overlapping cardboard; when the photoelectric eye detects cardboard overlapping, the paper feeding device can be controlled to stop feeding paper through a controller.

[0005] The separating member is a baffle plate, and there is a spacing between the baffle plate and the conveying surface of the cardboard conveying device that only allows one cardboard to pass through.

[0006] The cardboard overlapping detection mechanism includes a paper pressing wheel and a swing arm. The swing arm is rotatably arranged. The paper pressing wheel is connected to one end of the swing arm, and the photoelectric eye faces the other end of the swing arm.

[0007] The invention comprises a cardboard slitting mechanism, which comprises a slitting knife, a slitting roller and a plurality of guide rollers. The slitting roller is connected to a slitting power source for driving the slitting roller to rotate. A paper pressing belt is wound around the plurality of guide rollers. The paper pressing belt acts on the slitting roller. A paper inlet and a paper outlet are provided between the paper pressing belt and the slitting roller. The cardboard conveying device is located at the paper inlet.

[0008] According to the cardboard slitting machine for preventing cardboard overlapping conveying provided by the utility model, a cardboard separation mechanism and a cardboard overlap detection mechanism are arranged above the cardboard conveying device, so that when multiple overlapping cardboards are conveyed, separation can be achieved and the paper feeding device can be immediately controlled to stop feeding paper. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a three-dimensional diagram of the utility model;

[0010] Figure 2 for Figure 1 Sectional view in the AA direction;

[0011] Figure 3 It is a structural schematic diagram of the cardboard overlap detection mechanism. DETAILED DESCRIPTION

[0012] like Figure 1 As shown, the cardboard slitting machine for preventing cardboard from overlapping and conveying comprises a paper feeding device 1 and a cardboard conveying device 2. The paper feeding device 1 transfers the cardboards one by one to the cardboard conveying device 2, and the cardboard conveying device 2 conveys the cardboards to the cardboard slitting mechanism 3 for slitting. In order to solve the deficiencies in the prior art, the utility model is provided with a cardboard separation mechanism and a cardboard overlap detection mechanism above the cardboard conveying device 2. The cardboard overlap detection mechanism comprises a photoelectric eye (23), and the cardboard separation mechanism comprises a separation member for separating the overlapping cardboards. When the photoelectric eye detects that the cardboards overlap, the controller controls the paper feeding device 1 to stop feeding the paper. After the cardboards are separated, the paper feeding device 1 feeds the paper again. In this way, it is not necessary for workers to climb very high to separate the cardboards, thereby improving the stability of the equipment automation.

[0013] This separation member is a paper baffle 4, such as Figure 1 As shown, there is a gap between the paper stopper 4 and the conveying surface of the paperboard conveying device that allows only one paperboard to pass through. This separation member has a simple structure, and only needs to leave a gap between the paper stopper 4 and the conveying surface of the paperboard conveying device 2 that allows only one paperboard to pass through, so as to prevent multiple overlapping paperboards from entering the paperboard cutting mechanism 3.

[0014] like Figure 3As shown, the cardboard overlap detection mechanism includes a paper pressing wheel 21 and a swing arm 22. The swing arm 22 is rotatably arranged. The paper pressing wheel 21 is connected to one end of the swing arm 22, and the photoelectric eye 23 faces the other end of the swing arm 22. When the overlapped paperboard enters under the paper pressing wheel 21, the paperboard will cause the paper pressing wheel 21 to move upward, so that the swing arm 22 will swing, and the photoelectric eye 23 can detect the swing of the swing arm 22, thereby sending a signal to the controller, and the controller controls the paper feeding device 1 to stop feeding paper.

[0015] Finally, it is worth mentioning that this slitting machine includes a cardboard slitting mechanism 3, such as Figure 2 As shown, the cardboard slitting mechanism 3 includes a slitting knife 31, a slitting roller 30 and a plurality of guide rollers 33. The slitting roller 30 is connected to a slitting power source for driving the slitting roller 30. A paper pressing belt 32 is wound around the plurality of guide rollers 33. The paper pressing belt 32 acts on the slitting roller 30. A paper inlet 34 and a paper outlet 35 are provided between the paper pressing belt 32 and the slitting roller 30. The cardboard conveying device 2 is located at the paper inlet 34. Driven by the slitting power source, the slitting roller 30 rotates, and the cardboard enters from the feed port between the paper pressing belt 32 and the slitting roller 30. Under the pressure of the paper pressing belt 32, the cardboard is attached to the slitting roller 30. As the slitting roller 30 rotates, the slitting knife 31 slits the cardboard.
