Problems solved by technology

[0002] In the prior art, most of the paper cups and bowls used in large quantities now use plastic lids to match them, instead of green and environmentally friendly paper lids. The main reason is that paper lids are different from other materials. Soft in nature, not easy to shape
At present, the paper cover products in the domestic market are produced by using threaded tubes to roll up the paper cover sheet. In this way, the size, size and quality of the paper cover cannot be accurately grasped. The production process is complicated and the production equipment is very complicated. Many, high cost, not conducive to mass production

Embodiment Construction

[0011] The relevant details are further described below. The forming process of the circular paper cover includes the following forming steps: 1. Transfer the paper ring to the forming platform; 2. Fold the face paper, and then transfer the folded face paper to the paper ring on the forming platform 3. Fold the upper end of the paper circle inwardly so that the folded bottom of the paper circle covers the folded edge of the tissue paper; 4. Compound the folded edge of the tissue paper between the inner wall of the paper circle and the folded bottom; 5. Carry out indentation on the outer peripheral surface of the paper ring to form a water injection line; 6. Collect the formed paper cover.

[0012] The composite in step 4 adopts ultrasonic ironing or embossing ironing, and the corresponding paper circle and the face paper are provided with a film layer. When ultrasonic ironing or embossing ironing is used, the film layer between the composite parts is bonded .

Abstract

The invention discloses a round paper cover forming technology. The round paper cover forming technology is characterized by comprising the following forming steps that firstly, a paper ring is transmitted to a forming platform; secondly, a tissue is subjected to edge folding, and then the tissue obtained after edge folding is transmitted into the paper ring on the forming platform; thirdly, inward bottom folding is conducted on the upper end of the paper ring so that the folded bottom of the paper ring can wrap the folded edge of the tissue; fourthly, the folded edge of the tissue is compounded between the inner ring of the paper ring and the folded bottom; fifthly, indentation is conducted on the outer circumferential face of the paper ring, and a water injection line is formed; and sixthly, a formed paper cover is collected. The round paper cover forming technology is reasonable in technological step and fast and stable in forming.

Description

technical field [0001] The invention relates to an improved invention in the field of paper cover molding, in particular to an improved invention in a circular paper cover forming process. Background technique [0002] In the prior art, most of the paper cups and bowls used in large quantities are matched with plastic lids instead of green paper lids. The reason is that paper lids are different from other materials. The essence is soft and not easy to set. At present, the paper cover products in the domestic market are produced by using threaded tubes and rolling the mouth of the paper cover sheet. In this way, the size, size and quality of the paper cover cannot be accurately grasped, and the production process is complicated. Many, high cost, not conducive to mass production. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a stable and rapid round paper cover mol...
