Embodiment 1

[0037] A production process of disposable paper spoons,

[0038] S1 paper feeding (feeding), the paper thickness is 1mm.

[0039] S2 cleaning and sterilization.

[0040] S3

[0041] a) Put the paper blank into the forming space of the stamping die of the spoon, wherein the corresponding part of the stamping die and the spoon holding part is the forming surface of the holding part, and the corresponding part of the stamping die and the handle part of the spoon is the forming surface of the holding part (using The upper and lower molds, the molding surface is the upper and lower inner cavity surfaces), the cavity surrounded by the forming surface of the receiving part is concave (corresponding to the convex surface of the upper cavity, and the concave surface of the lower cavity), the cavity surrounded by the forming surface of the handle part It is curved (corresponding to the convex surface of the upper chamber and the depression of the lower chamber surface), embossed protr...

Embodiment 2

[0045] The difference between Embodiment 2, Embodiment 3, Embodiment 4, Embodiment 5 and Embodiment 1 lies in the parameters of embossing protrusions. The relevant parameters are shown in Table 1.

Embodiment 6

[0047] like figure 2 The difference between the illustrated embodiment 6 and the embodiment 5 lies in that only several embossed protrusions are distributed on the forming surface of the receiving portion.

Abstract

The invention relates to the field of tableware, and discloses a disposable paper tableware production process. The disposable paper tableware production process comprises the step of stamping forming, and is characterized in that (a), a paper blank is placed in a forming space of a stamping die, the part of the stamping die, which corresponds to a tableware containing part, is a containing part forming surface, a cavity formed by enclosing the containing part forming surface is in a concave shape, and embossed protrusions are arranged on the containing part forming surface and extend to the edge of the containing part forming surface; and (b), the stamping die fully contacts with the paper blank to form a formed product. The disposable paper tableware production process is technically improved on the basis of the stamping forming process, the operation is simple, and a production line does not need to be greatly improved. The processed tableware is free of wrinkles and high in attractiveness, diners can use the tableware more comfortably due to the fact that linear creases protruding out of the surface do not exist, and meanwhile, the strength of the disposable paper tableware is enhanced.

Description

technical field [0001] The invention relates to the field of tableware, in particular to a production process for disposable paper tableware. Background technique [0002] With the acceleration of the pace of life, eating out and ordering takeaway meals have become the choice of many people, and the use of disposable tableware is also increasing. At present, the most common ones are disposable plastic tableware, which are mostly made of polymer materials such as polypropylene and polystyrene, as well as harmful fillers. When burned, a large amount of toxic gas will be released, and it will not rot even if it is buried underground for hundreds of years. , causing long-term serious harm to the environment, and harmful fillers are easily dissolved in food, affecting human health. [0003] Therefore, paper tableware has been researched and explored in the industry, hoping to find a substitute for disposable plastic tableware. Paper tableware has become an alternative to plastic...
