Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to an edge trimming device for corrugated cardboard processing. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made of at least one layer of corrugated paper and one layer of linerboard bonded together. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. It is made by pulping straw pulp and waste paper to make a paperboard similar to yellow cardboard, which is then mechanically rolled into a corrugated shape. Finally, it is bonded to the linerboard with adhesives such as sodium silicate. After the corrugated cardboard processing plant completes the multi-layer corrugated cardboard composite processing, it needs to be crimped and cut according to the shape and size of the carton so that the cardboard can be further processed into cartons.

[0003] Existing edge trimming devices for corrugated cardboard processing typically only have a single straight trimming or circumferential trimming function. When a carton needs to be trimmed in both straight and circumferential directions, two separate devices are required, which affects the processing efficiency of the carton. Therefore, we propose an edge trimming device for corrugated cardboard processing. Utility Model Content

The surface of the lead screw 7 is threaded with a threaded block 8. The top of the threaded block 8 is fixedly connected to one end of the support frame 5. The guide rod 2 is installed inside the guide groove 9 on the other side. The threaded block 8 slidably connected to the surface of the guide rod 2 is fixedly connected to the other end of the support frame 5.

[0023] Two symmetrical guide grooves 9 are opened on the top of the base 1 to install guide rod 2 and lead screw 7 respectively. Guide rod 2 is connected to one end of support frame 5 through threaded block 8, and lead screw 7 is connected to the other end of support frame 5 through threaded block 8. The lead screw 7 is driven to rotate by motor 10 outside the base 1. The lead screw 7 drives threaded block 8 and support frame 5 to move laterally in the guide groove 9. Support frame 5 drives disc 3 and cutter head 15 to move laterally to perform straight trimming of corrugated cardboard.

[0024] Based on the aforementioned scheme, the adjustment assembly includes a second lead screw 11, a second threaded block 12, a slide groove 13, and a rocker arm 14.

A negative pressure is formed inside the limiting hole 16, which adsorbs the corrugated cardboard onto the surface of the base 1, realizing the limiting and fixing of the corrugated cardboard. Then, according to the trimming requirements of the corrugated cardboard, when straight trimming of the corrugated cardboard is required, the cutter head 15 is first adjusted to above the trimming position. Then, the electric lifting rod 4 is started to control the cutter head 15 to move downward. Subsequently, the motor 10 is started to drive the lead screw 7 to rotate. The lead screw 7 drives the threaded block 8 and the support frame 5 in the guide groove 9. Laterally, the support frame 5 drives the disc 3 and the cutter head 15 to move laterally, performing straight-line trimming on the corrugated cardboard. When circumferential trimming is required, the rocker arm 14 outside the disc 3 is rotated according to the outer diameter of the corrugated cardboard, driving the lead screw 11 to rotate. The lead screw 11 drives the threaded block 12 and the cutter head 15 to slide in the groove 13, adjusting the distance between the cutter head 15 and the center of the disc 3 so that the cutter head 15 is located at the edge of the corrugated cardboard. Then, the electric lifting rod 4 is started to control the cutter head 15 to move downward. Subsequently, the motor 6 is started to drive the disc 3 and the cutter head 15 to move in a circular motion, performing circumferential trimming on the corrugated cardboard. Both straight-line and circumferential trimming of the corrugated cardboard can be performed, resulting in higher processing efficiency.
