Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board processing, in particular to a stable shearing machine. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of wavy core paper interlayer (commonly known as "corrugated paper", "corrugated core paper", "corrugated paper core", "corrugated base paper") and a layer of cardboard (also known as "box board", "box board"). It has high mechanical strength and can withstand collisions and falls during transportation. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard and the structure of the carton itself.

[0003] During the processing of corrugated cardboard, it is necessary to cut it with a shearing machine. Chinese patent publication number CN219310219U, publication time 20230707, discloses a stable shearing machine, including a workbench, a cutting machine and a stabilizing device. The surface of the workbench is fixedly connected to the cutting machine, and the longitudinal section of the cutting machine is rectangular. The stabilizing device is arranged on the surface of the cutting machine. The stabilizing device includes a supporting bar, which is fixedly connected to the surface of the cutting machine. The longitudinal section of the supporting bar is long strip-shaped. A placing bar is placed on the surface of the supporting bar. The longitudinal section of the placing bar is long strip-shaped. The placing bar is in contact with the surface of the cutting machine, and a positioning rod is slidably connected to the inner surface of the placing bar.

[0004] Most of the existing shearing machines mentioned above directly mount a cutter assembly on a conveying assembly, and the cardboard is cut by vertically reciprocating movement of the cutter. In specific implementation, there are mostly limit assemblies at the outer side of the cardboard. When the cutter contacts the cardboard and completes the cardboard cutting, the cardboard is easily offset or lifted due to uneven force, resulting in an uneven cut. Therefore, a corresponding stable shearing machine is urgently needed to solve the above problem. Utility Model Content

A top frame is fixedly installed between the two groups of book search support seats, a push cylinder is fixedly installed on the top of the top frame, a tool is fixedly connected to the output end of the push cylinder through a connecting seat, a convex piece is fixedly installed on the outer wall of the connecting seat, and a positioning component for positioning a paperboard is arranged at the bottom of the convex piece.

[0008] Preferably, a mounting frame is fixedly mounted on the inner surface wall of the horizontal end of the top frame, a sliding sleeve is fixedly connected to the outer surface wall of the connecting seat via a fixing plate, and the inner surface wall of the sliding sleeve is slidably connected to the outer surface wall of the vertical end of the mounting frame.

[0009] Preferably, the positioning assembly includes a pressure seat, the protruding piece and the connecting seat are integrally formed, and a spring is fixedly installed between the pressure seat and the protruding piece.

[0010] Preferably, a shock absorber is penetrated through the inner surface wall of the spring, the bottom of the shock absorber is fixedly connected to the pressure seat, and the output end of the shock absorber is fixedly connected to the protruding piece.

[0012] Preferably, a fixing frame is fixedly installed at the bottom of the vertical end of the top frame, and a connecting piece is integrally formed on the outer wall of the fixing frame, and the connecting piece is fixedly connected to the support seat through a fastening rod.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0014] 1. In the present application, the spacing between the two groups of conveying components is set, which does not affect the conveying of the cardboard while providing vertical activity space for the tool. The output end of the push cylinder drives the tool to move downward through the connecting seat. The connecting seat is linked to the spring pressure seat through the convex piece. The pressure seat first contacts the outer wall of the cardboard and is placed on the outside of the area to be cut. Then the connecting seat and the tool continue to move downward, the spring is compressed, and the pressure seat completes the positioning of the cardboard until the tool completes the cutting of the cardboard. In this way, the deviation of the cardboard during the cutting process is limited by the two groups of pressure seats, which ensures the stable progress of the cutting process, thereby improving the stability of the shearing machine.
