A kind of production method of U-shaped pin pier
Technical field
The present invention relates to a kind of U-shaped pin pier, be specifically related to a kind of production method of U-shaped pin pier, belong to field of packaging material.
Background technology
U-shaped pin pier is a base part conventional in packaging material, in transport and keeping process, product is played to effective protection and supporting role. Traditional production method be by manual operation, sheet paper is bent into U-shaped, troublesome poeration, efficiency is low, human input is large, and the quality of pin pier is uneven.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to overcome the defect of prior art, the production method of the U-shaped pin pier that a kind of efficiency is high, of fine quality and stable is provided.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A production method for U-shaped pin pier, comprises the following steps:
(1), cross cutting: cop tube paper is die-cut to the specification needing;
(2), gluing: by the wherein one side gluing of cop tube paper good step (1) cross cutting;
(3), gummed: by overlapping cop tube paper good step (2) the gluing required number of plies, the formation semi-finished product of being glued to;
(4), compressing: the semi-finished product of step (3) to be placed between two board pressing plates of forming machine, forming jig is close to semi-finished product under the effect of forming cylinder, board pressing plate changes to parallel to each other by the herringbone of original state under the effect of pressing plate cylinder, between distance equate with the distance from bottom of original state, forming jig continues motion, semi-finished product are depressed into moulding table top, make U-shaped pin pier finished product, distance when its bottom size is parallel to each other by board pressing plate determines.
Further, in abovementioned steps (2), adopt roller bearing band glue method to cop tube paper gluing.
Further, the semi-finished product in abovementioned steps (3) are formed by 10 overlapping gummeds of cop tube paper.
Usefulness of the present invention is: the production method of U-shaped pin pier of the present invention, and efficiency is high, and human input is few, and good product quality and stable, has greatly saved production cost and has improved yield.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, the production method of a kind of U-shaped pin pier of the present invention, comprises following four steps: (1), cross cutting: the specification that cop tube paper is die-cut to needs; (2), gluing: by the wherein one side gluing of cop tube paper good step (1) cross cutting; (3), gummed: be glued to the required number of plies by overlapping cop tube paper good step (2) gluing, form semi-finished product 4, its end face and bottom surface are not all to be with glue; (4), compressing: as shown in Figures 3 to 5, the semi-finished product 4 of step (3) are placed between two board pressing plates 1 of forming machine, forming jig 2 is close to semi-finished product 4 under the effect of forming cylinder 3, board pressing plate 1 changes to parallel to each other by initial herringbone under the effect of pressing plate cylinder 5, between distance equate with the distance from bottom of initial position, forming jig 2 continues motion, semi-finished product 4 are depressed into moulding table top 6, make U-shaped pin pier finished product, distance when its bottom size is parallel to each other by board pressing plate 1 determines.
As shown in Figure 2, in the present invention, adopt roller bearing band glue method to cop tube paper 9 gluings. Specifically, a pair of roller bearing 7 is setting up and down, and cop tube paper 9 is sidelong in the middle of roller bearing 7 from one, wherein, below, the Lower Half of that roller bearing 7 immerses in packing element 8, so, after roller bearing 7 rotates, the wherein one side of cop tube paper 9, by gluing, is transmitted out from the opposite side of roller bearing 7 simultaneously.
Preferred as one, semi-finished product 4 are formed by 10 overlapping gummeds of cop tube paper 9, can ensure to reach requirement of strength, are convenient to again compressing. So, the production method of U-shaped pin pier of the present invention can be produced the U-shaped pin pier that quality is good and stable efficiently.
More than show and described general principle of the present invention, principal character and advantage. The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
