Embodiment 1

[0052] In order to reduce the difficulty of folding, our solution is to reduce the width of the upper plane or lower plane connecting part of the part that needs to be folded after cutting, that is, the length of the folding line. The section of the corrugated plate at the cutting position of the lower plane is as follows Figure 5 As shown, the folded top view is as follows Figure 6 shown. From Figure 5 It can be seen that the lower plane and the slope surface of the lower plane cutting position are completely cut off, and the upper plane is cut by 2 / 3, leaving a 1 / 3 width of the upper plane connecting part, so the difficulty in the folding process is probably reduced to that of the comparative example 2 1 / 3 of. The shape of the folded honeycomb is not significantly different from that of Comparative Example 2, except that the width of the upper and lower plane connecting parts that have not been disconnected from the upper and lower surfaces is reduced. After heat setti...

Embodiment 2

[0064]In this example, the direction of the corrugated plate is different from that of Embodiment 1, where the direction of the grooves of the corrugated plate is perpendicular to the length direction of the material. The production of corrugated board can still be carried out by hot pressing plastic film with rollers, but the direction of the protrusion on the roller is not the circumferential direction, but the axial extension. The two rollers are like gears meshing with each other. After the plastic film passes through the roller, the corrugated board The upper plane, the slope surface, and the lower plane are produced one by one in sequence.

[0065] The running direction of the corrugated sheet, such as Figure 14 shown. During dislocation cutting, the upper and lower pressing blocks clamp the material, causing the upper and lower planes to bend and deform; the upper and lower pressing blocks move forward with the clamped corrugated plate, and the upper and lower blades ...

Abstract

The invention relates to a plastic honeycomb. A corrugated plate with an upper plane, a lower plane and a slope surface are adopted as a raw material, and the plastic honeycomb is folded after staggering cutting. The plastic honeycomb is characterized in that a cutting part of the upper plane comprises the upper plane, the slope surface and a part of the lower plane, the rest of the other part ofthe lower plane serves as a folding connecting part, the cutting part of the lower plane cutting part comprises a lower plane, a slope surface and a part of the upper plane, and the rest of the otherpart of the upper plane serves as a folding connecting part. Compared with the prior art, the cutting amplitude is larger, and the follow-up folding is easier. By the adopted means, the corrugated plate is mainly deformed by pressing blocks, and the plane to be partially cut is changed into the curved surface of the ridge shape and the shape of the inverted ridge, so that partial cutting is easy to realize.

Description

technical field [0001] The invention relates to a plastic honeycomb and its production method and device. Background technique [0002] Honeycomb material has a hollow structure, so it is widely used in occasions that require light weight, such as aircraft, motor vehicles, auto parts, compartment panels of vans, various packaging materials, etc. [0003] The materials of honeycomb materials are also various, such as aluminum honeycomb, aramid honeycomb, paper honeycomb and so on. In the early days, auto parts mostly used paper honeycombs. Because paper honeycombs are made of waste paper, they are prone to odor problems, so now they tend to be replaced by plastic honeycombs. [0004] There are two main production processes of plastic honeycomb, one is round tube honeycomb and the other is folded honeycomb. [0005] The production process of the round tube honeycomb is relatively complicated. First, a certain length of round tube needs to be produced, and the surface of the ...
