Description

Technical Field

[0001] The utility model relates to an improved utility model of honeycomb paper core processing equipment, in particular to a cross-cutting mechanism of the honeycomb paper core processing equipment. Background Art

[0002] The core board is composed of multiple core papers. The core board is sent to the cross-cutting station. The cross-cutting mechanism cuts the core board into core strips, which are then composited and compacted to form a continuous honeycomb core.

[0003] The upper blade of the core board cross-cutting mechanism is installed on the blade holder, which is driven by the crank slider mechanism to rise and fall on the linear guide rail to achieve high-speed cutting. The bite point of the upper and lower blades of the existing cross-cutting mechanism is far away from the force point of the blade holder on the guide rail and is not at the same height. This can easily lead to two problems during cutting. First, the upper blade may give way, resulting in uneven cuts on the paper core strips. Figure 1 As shown, the paper core strips typically have beveled cuts. After the paper core strips are laminated and compacted, the surface of the honeycomb core needs to be rolled and polished to smooth the bevels before being laminated with the face paper to form honeycomb paperboard. Secondly, the linear guide's ball bearings can become stuck, shortening the guide's service life. Summary of the Invention

[0004] In view of the technical problems existing in the background technology, the technical problem solved by the present invention is to provide a cross-cutting mechanism of a honeycomb paper core processing equipment with good cutting effect and long service life.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: the cross-cutting mechanism of the honeycomb paper core processing equipment is characterized by comprising an upper knife component and a guide component,

[0006] The upper knife component includes an upper knife seat and an upper knife installed on the upper knife seat;

[0007] The guide component includes a vertically arranged guide member and a sliding member slidably arranged on the guide member. The upper knife seat is connected to the sliding member or the upper knife seat and the sliding member are an integral structure. Both ends of the guide member are installed on the frame. The lower end of the guide member is not higher than the cutting height, and the height of the stop end of the sliding member moving downward along the guide member is not higher than the cutting height.

[0008] The stop ends of the guide member and the sliding member of the utility model move downward, and the force point moves downward. When the upper knife seat moves downward through the sliding member and the guide member, the upper knife and the lower knife engage and cut. The cutting force of the upper knife is supported by the guide member, which solves the problem of the upper knife giving way. The paper core strips after cutting are smooth, and the honeycomb paper core does not need to be polished, which greatly improves the quality of the honeycomb paper core. At the same time, it also improves the service life of the upper knife and the service life of the guide member and the sliding member.
