Description

Cutting device for paper pulp molding product

Technical Field

The utility model relates to a pulp moulding product production technical field especially relates to a cutting device for pulp moulding product.

Background

At present, with the increase of environmental awareness, more and more pulp molded products are applied to packaging. But the production of the paper holder needs a certain draft angle to produce, so that the gap between the lower part of the inner package and the outer package is increased, and the swing is increased; the edges of the paper supports are not neat, the edges can be neat and beautiful only by trimming, but more than or equal to 0.8mm needs to be left when the paper supports are vertically cut, and the paper supports are more difficult to be matched with the upper part of an outer package in order! Sometimes, the paper support is required to be subjected to a side cutting process, so that the gap position between the paper support and the outer package is saved, and the cut can be tidy. That is to cross cut the paper! Unlike the habitually placing paper on a chopping board, the paper is vertically acted by a blade to cut off the pulp molding product.

As more applications are made to the inner wrapper, the aesthetic appearance is also considered! Therefore, the side cutting process is increased from 10% to 35% in this year, and the number of side cutting dies and special machines is increased.

In the production of pulp moulding, the straight cut product generally has 90 deg. flanged edge, and the product can be placed on the profile modeling (the profile modeling is also a bearing chopping block), and the general and ordinary machine can be used to drive the knife edge to make it move up and down, and when the force is acted on the paper support which is supported on the chopping block, the paper can be cut off! The special mold is not necessary, and the model is general!

Because the paper product is soft, the side surface can deform when being stressed greatly; therefore, when the paper is cut off laterally, the paper is generally put in firstly, then the profiling is closed to be positioned and supported in the inner part, and then the lower machine table and the fixed die are driven to move forwards, backwards, leftwards and rightwards or circularly by the pushing of the oil cylinder, the air cylinder or the cam, so that the right-angled cutting edge on the outer frame of the die and the inner profiling act to cut off the side surface of the paper.

The following is an analysis of the conventional practice:

1. the machine is required to be moved down and can move back and forth, left and right or circularly. The general paper-plastic factories of the machines do not have! Few manufacturers!

2. The machine has complex action and low production efficiency!

3. Due to the different shapes of the paper support products, a special mold is required. However, such molds have few manufacturers and are difficult to make! Long time!

4. The special side cutting die has complex structure, difficult maintenance and high price!

In conclusion, equipment and special molds need to be purchased newly, the cost is high, the time is long, and the production efficiency is low, so most paper-plastic product factories do not connect side-cutting paper support products at the present stage.
