Description

TECHNICAL FIELD

[0001] The utility model relates to printing and packaging edge cutting technical field, concretely is an edge cutter for printing and packaging. BACKGROUND

[0002] Printing and packaging refers to a way of printing text and design elements on packaging materials through various printing techniques. The edge cutter for printing and packaging is a device used in the printing and packaging industry, mainly for cutting and edge processing of printed matter or packaging materials.

[0003] As disclosed in Chinese patent CN214191934U, the double extension shaft motor can drive the first rotating rod and the second rotating rod to rotate. The first taper gear and the second taper gear cooperate, and the third taper gear and the fourth taper gear cooperate to drive the first screw rod and the second screw rod to rotate, so that the moving table and the moving plate move synchronously. Workers do not need to adjust the position of the edge cutter and the moving table separately, which improves efficiency and accuracy. The pressure roller can fix the packaging material and improve the stability during edge cutting.

[0004] For this structure, although it can cut the edges of printing and packaging, the edge cutter will wear out after long-term use, resulting in poor cutting accuracy. The edge cutter of this structure is not easy to replace, so we propose an edge cutter for printing and packaging that can quickly replace the edge cutter to improve the cutting effect.

[0014] 1. The edge cutter for printing and packaging is composed of a disassembly and assembly assembly. In the printing and packaging process, the excess material needs to be cut, the knife handle and the edge cutter are pushed by the hydraulic cylinder to cut the material, and the edge cutter needs to be replaced after being used for a long time. At this time, the pressing plate is pressed, the pressing plate drives the pressing plate to move downward, the end of the pressing plate is in contact with the inclined surface of the sleeve, the sleeve slides on the outer wall of the fixed plate, and the spring is compressed. At this time, the sleeve drives the hook fixedly installed at the bottom to slide, the hook is no longer connected with the clamping groove on the outer wall of the edge cutter, and the edge cutter can be replaced. When the edge cutter and the knife handle are disassembled, the pressing plate is not pressed, and the sleeve is reset under the elasticity of the spring. The end of the pressing plate is in contact with the inclined surface of the sleeve, the pressing plate is reset, and when a new edge cutter needs to be installed, the clamping groove on the outer wall of the edge cutter is aligned with the hook, the inner wall of the clamping groove is in contact with the inclined surface of the end of the hook, the hook drives the sleeve to slide, the sleeve compresses the spring, the hook is not pressed when the hook is completely connected with the clamping groove, the spring resets the sleeve and the hook, and the hook is disconnected with the clamping groove.
