Problems solved by technology
Facts and experiments show that the sieve mold is only suitable for the processing of low concentration and thin pulp molded products
Because the sieve mold is not easy to release, it cannot be used for the processing of honeycomb paperboard with high concentration and abnormal thickness.
In addition, the sieve mold cannot realize continuous production

Embodiment Construction
[0022] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing thereof
[0023] like figure 1 , 2 In the shown embodiment of the device, the main frame is formed by connecting the frame 2 in the pulp dehydration area and the frame 1 in the honeycomb forming area, and the two frames are bounded by the dotted line a-a in the figure. The ring main frame is provided with an endless net type endless conveyor belt 3 supported by tension rollers 4 at both ends of the main frame and its guide rollers, and the main frame is provided with guide rails (not shown) supporting the two sides of the conveyor belt.
[0024] The right end of the main frame shown in the figure is the beginning of the device, which is provided with a bucket-shaped headbox 6 connected to the pulping device, and the headbox is provided with a pulp overflow port 5 that is conducive to stable pulp input. The frame 2 in the pulp dehydration area is equipped with an endl...

The invention relates to a honeycomb continuous shaping device of mould honeycomb paper plate in wet pulping process and relative mould. The inventive circulate protrusion section and circulate transmission band are one-time dewater section, whose distance between pulp outlets are smaller than inlets, the honeycomb shaping area is arranged with secondary dewater section, hydraulic device and bandmould formed by coupled press rollers, the surface of mould is uniformly distributed with honeycomb simulated hexagon protrusions, and the band contains stainless steel woven network liner. The invention, based on high-density ultra-weight constant wet paper plate, uses circulate band mould and protruding device to realize honeycomb continuous shaping of wet paper plate, which can improve qualityand realize environment friend or the like.
Description
technical field [0001] The invention belongs to pulp molding machinery, in particular to a honeycomb continuous molding device for wet processing pulp molding honeycomb paperboard. It constitutes a wet processing pulp molded honeycomb paperboard production line. The honeycomb paperboard processed by this forming device can become the basic material for making wood substitute honeycomb trays, honeycomb paperboard heavy-duty packaging boxes, building decorative panels and light walls after subsequent processes such as cutting, drying, and compounding. Background technique [0002] As we all know, pulp molded honeycomb paperboard is superior to honeycomb paperboard in main technical indicators such as compressive strength, bending strength, moisture resistance and water resistance. However, the existing production equipment cannot meet the needs of high-quality, environment-friendly, high-strength, high-load and continuous production of pulp-molded honeycomb paperboard. The ma...
