Description

Technical Field

[0001] This utility model relates to the technical field of packaging paper processing equipment, specifically a slitting device for packaging paper. Background Technology

[0002] In the production and processing of packaging paper, slitting is a crucial step. Traditional slitting devices still have many problems, which seriously affect the production efficiency and product quality of packaging paper. Therefore, developing a slitting device for packaging paper is of great significance for improving the production efficiency and product quality of packaging paper.

[0003] A slitting device for packaging paper, as described in reference announcement number CN212072089U, includes a machine frame. Support legs are fixedly installed at the four corners of the bottom of the machine frame. Two cooperating conveyor frames are fixedly welded to the left and right sides of the top of the machine frame. Conveying rollers are rotatably installed in the inner cavity of each conveyor frame. A motor is connected to the front side of the lower conveyor roller, extending through to the front side of the conveyor frame. A paper feeding table is located at the center of the top of the machine frame. During the slitting process of packaging paper, this device utilizes the elasticity of springs to press the pressure rollers against both sides of the paper cut, preventing the cut from bending or folding due to its own internal stress. This ensures the flatness of the slitting paper, facilitating subsequent processing, and guaranteeing a high yield rate, saving resources and improving production efficiency. However, while this device can be effectively applied, the cutting components are typically positioned in a designated area, making it difficult to rotate them, thus affecting the slitting efficiency of the packaging paper and frequently causing problems for users. Utility Model Content

[0004] The purpose of this utility model is to provide a slitting device for packaging paper, so as to solve the problem that although the device proposed in the background art can be applied well, the cutting component is usually set in a designated area, which makes it difficult to rotate the cutting component, thus affecting the slitting efficiency of the cutting component for packaging paper.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slitting device for packaging paper, comprising a frame, an unwinding roller rotatably mounted on the inner wall of one side of the frame, a first guide roller rotatably mounted on the inner wall of the frame above the unwinding roller, a lower roller rotatably mounted on the inner wall of the frame on one side of the first guide roller, a cutting roller above the lower roller, a plurality of cutting blades mounted on the outer wall of the cutting roller, slitting grooves provided on the outer wall of the lower roller below the cutting blades, a first transmission box located on the outer wall of one side of the frame at the position of the cutting roller, and a first motor mounted on the inner wall of one side of the frame below the lower roller. One end of the first motor extends into the interior of the first transmission box and is equipped with a first belt drive structure. The end of the first belt drive structure away from the first motor is connected to one end of the cutter roller. A first gear is fixed on the outer wall of one side of the cutter roller, and a second gear is fixed on the outer wall of the lower roller below the first gear. The second gear meshes with the first gear. A second transmission box is provided on the frame surface on one side of the first transmission box. A control panel is installed at the lower end of the surface of the second transmission box. The output terminal of the microcontroller inside the control panel is electrically connected to the input terminal of the first motor. Support feet are installed at the corner positions at the bottom of the frame.

[0006] Preferably, a lower pressure roller is rotatably mounted on the inner wall of the frame on the side of the lower roller away from the first guide roller, and an upper pressure roller is provided above the lower pressure roller. The arrangement of the lower pressure roller and the upper pressure roller is used to roll and flatten the packaging paper.

[0007] Preferably, both ends of the upper pressure roller are rotatably mounted with lifting seats, and the outer wall of the lifting seats is slidably connected to the inner wall of the frame. The lifting seats are provided to allow for the movable placement of the upper pressure roller.

[0008] Preferably, the top of the frame at the lifting seat position is equipped with a lifting drive component via a bracket. The input end of the lifting drive component is electrically connected to the output end of the microcontroller inside the control panel, and the bottom end of the lifting drive component is connected to the top end of the lifting seat. The lifting drive component is configured to drive the lifting seat to perform lifting operations.

[0009] Preferably, both ends of the cutter roller are rotatably mounted with a support frame, and the end of the support frame away from the cutter roller is connected to the top of the machine frame. The support frame is used to position the cutter roller.

[0010] Preferably, a second guide roller is rotatably mounted on the inner wall of the frame on the side of the upper pressure roller away from the cutter roller, and a take-up roller is rotatably mounted on the inner wall of the frame on the side of the second guide roller away from the upper pressure roller. The take-up roller is configured to wind and store the slit packaging paper.

[0011] Preferably, a second motor is installed on the inner wall of the frame below the take-up roller. The input end of the second motor is electrically connected to the output end of the microcontroller inside the control panel. One end of the second motor extends into the interior of the second transmission box and is provided with a second belt drive structure. The end of the second belt drive structure away from the second motor is connected to one end of the take-up roller. The second motor is configured to drive the second belt drive structure to operate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the slitting device for packaging paper not only ensures the slitting efficiency of the packaging paper during use, but also ensures the flatness of the packaging paper, and achieves the purpose of automating the slitting and winding of the packaging paper.

[0013] (1) The first belt drive structure is driven by the first motor to rotate, and the first belt drive structure drives the cutter roller to rotate. Because the first gear and the second gear mesh with each other, the cutter roller drives the lower roller to rotate in the opposite direction. When the packaging paper is inserted between the cutter roller and the lower roller, the rotating cutter will be in the slitting groove area to cut the packaging paper, thereby ensuring the slitting efficiency of the packaging paper when the slitting device is used.

[0014] (2) The lifting seat is driven to rise and fall by the lifting drive component, so that the lifting seat drives the upper pressure roller to rise and fall smoothly, thereby adjusting the distance between the upper pressure roller and the lower pressure roller. When the cut packaging paper is inserted between the upper pressure roller and the lower pressure roller, the upper pressure roller and the lower pressure roller will roll and flatten the cut packaging paper, thereby ensuring the flatness of the packaging paper.

[0015] (3) By winding the packaging paper to be cut onto the outer wall of the unwinding roller, one end of the packaging paper is guided by the first guide roller and passes through the upper part of the lower roller and the lower pressure roller. Then, the packaging paper is guided by the second guide roller and connected to the outer wall of the take-up roller. When the second motor drives the take-up roller to rotate through the second belt drive structure, the unwinding roller unwinds the packaging paper and the take-up roller takes the packaging paper back up, so that the packaging paper is cut into several parts by several cutters, thereby achieving the purpose of automatically cutting and winding the packaging paper.
