Abstract
The invention discloses a paper cover integrated forming process, which is characterized in that: the method comprises the following forming steps of firstly, preparing round paper; prepressing the circular paper to form a cover surface and a paper ring which are connected, wherein the cover surface is an arc-shaped cover surface which is bulged upwards; pressing the arc cover surface for the second time, forming a sunken part in the middle of the arc cover surface, forming a clamping groove between the side wall of the sunken part and the paper ring, and buckling the clamping groove with a roll opening at the upper end of the paper container in a matching manner; step four, forming a reinforcing structure at the lower end of the paper ring; and fifthly, discharging finished products. The invention adopts paper to rapidly form, saves materials and has stable structure of the manufactured paper cover.
Description
Technical Field
The invention relates to an improved invention in the field of paper cover forming, in particular to an improved invention of a paper cover integral forming process.
Background
In the prior art, the paper cover comprises a paper ring and a cover surface which are formed in a split mode, the paper ring and the cover surface are overlapped to form the clamping groove, the upper end of the corresponding paper ring is inwards folded to form an overlapping part, the overlapping part is connected with the outer edge of the cover surface, a sunken part is formed in the middle of the cover surface in a pressing mode, and the clamping groove is formed between the side wall of the sunken part and the paper ring.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide an integrated forming process of the paper cover, which is rapid in forming and saves materials.
In order to solve the technical problems, the invention is realized by adopting the following technical scheme: the paper cover integrated forming process is characterized in that: the method comprises the following forming steps of firstly, preparing round paper; prepressing the circular paper to form a cover surface and a paper ring which are connected, wherein the cover surface is an arc-shaped cover surface which is bulged upwards; pressing the arc cover surface for the second time, forming a sunken part in the middle of the arc cover surface, forming a clamping groove between the side wall of the sunken part and the paper ring, and buckling the clamping groove in a matched manner with the roll opening at the upper end of the paper container; step four, forming a reinforcing structure at the lower end of the paper ring; and fifthly, discharging finished products.
The reinforcing structure is formed by heating, inward folding and knurling the lower end of the paper ring in sequence.
The reinforcing structure is formed by heating and outward curling the lower end of the paper ring in sequence.
After the paper ring is heated, the cover surface corresponding to the upper side of the clamping groove is leveled by mould pressing.
The circular paper is formed by unreeling and punching roll paper.
The bottom of the sunken part is a flat bottom.
The improved paper cover integrated forming process has the advantages that the improved paper cover integrated forming process adopts one-step paper forming, reduces waste generation, saves materials, forms the arc-shaped cover surface and the paper ring through prepressing, forms a sunken part on the arc-shaped cover surface through two-step pressing forming, and ensures the forming effect; meanwhile, the lower end of the paper ring is formed with a reinforcing structure such as a curled edge or a folded bottom, and the overall structural strength of the paper cover is improved.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
FIG. 1 is a first process flow diagram of the present invention.
FIG. 2 is a second process flow diagram of the present invention.
Detailed Description
The drawings show the structure of the invention, and the details thereof are further described below with reference to the drawings. In the embodiment, referring to fig. 1 and fig. 2, the paper cover integrated forming process includes the following forming steps, step one, preparing circular paper; secondly, prepressing the circular paper through a nest edge die, and forming a cover surface and a paper ring which are connected, wherein the cover surface is an arc cover surface which is bulged upwards; pressing the arc cover surface for the second time, forming a sunken part in the middle of the arc cover surface, forming a clamping groove between the side wall of the sunken part and the paper ring, and buckling the clamping groove with a roll opening at the upper end of the paper container in a matching manner; step four, forming a reinforcing structure at the lower end of the paper ring; and fifthly, discharging finished products, wherein the finished products can be conveyed out by a conveying belt.
As a further improved specific implementation manner, referring to fig. 1, the reinforcing structure is formed by heating, folding the bottom inwards and knurling the lower end of the paper ring in sequence, and specifically, the lower end of the paper ring is heated and softened by hot air, then folded by the bottom folding mold inwards, and then knurled by the knurling mold to be attached to the paper ring.
As a further improved specific implementation manner, referring to fig. 2, the reinforcing structure is that the lower end of the paper ring is sequentially subjected to heating and outer hemming molding, and specifically, the lower end of the paper ring is heated and softened by hot air and then subjected to outer hemming molding by a hemming mold.
As a specific implementation mode of further improvement, after the paper ring is heated, the cover surface corresponding to the upper side of the clamping groove is flattened through mould pressing, the integral strength of the paper cover is enhanced, and the sequence of flattening, external curling, internal folding bottom and knurling forming can be changed.
As a specific embodiment of further improvement, the circular paper is formed by unreeling and punching roll paper, specifically, the roll paper is unreeled to a punching die, and the circular paper is formed by punching the punching die.
As a specific implementation mode of further improvement, the bottom of the sunken part is flat, so that the side wall of the sunken part is uniformly supported, and the buckling effect of the clamping groove is guaranteed.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
