Embodiment 1

[0017] The production method of the drawing sheet in this embodiment uses PP board 1 as the base material, and adopts a high-temperature die-cutting method to process and manufacture. The die-cutting machine and the mold are all made of high-temperature-resistant materials. To 120 ℃ ~ 135 ℃, spread the PP board 1 on the lower die table of the die-cutting machine, and the upper die moves from top to bottom to the lower die to cut. The contact time between the upper die cutter and the PP board 1 is 0.5 seconds. Then the upper mold is retracted upwards, and the PP board 1 on the table of the lower mold forms a drawing picture with smooth sides and a hollowed-out pattern 2 required by the design shape. Cut into the specifications of length 268mm, width 250mm, the pattern position is centered, and the surrounding deviation ≤ 2mm single-piece drawing sheet, and finally pack it. Hollow pattern 2 has different patterns formed in each drawing sheet, such as figure 1 shown.

Abstract

The invention discloses a production method for a drawing sheet. The drawing sheet is processed and produced by adopting a high-temperature die cutting method. The production method takes a PP (Polypropylene) sheet as a base material and comprises the following specific steps: raising the temperature of an upper die-cutting rule to 120 to 135DEG C; flattening the PP sheet on a lower die tabletop of a die-cutting machine; enabling an upper die to downwards move from top to bottom for cutting; enabling the contact time of the upper die-cutting rule and the PP sheet to be 0.4 to 0.6 seconds, and then forcing the upper die to upwards retract, and forming the drawing sheet with smooth side surface and hollow-out patterns required by design shape on the PP sheet on the lower die tabletop. According to the production method disclosed by the invention, the processing temperature for die cutting is designed to be 120 to 135DEG C, so that products produced at the temperature of 120 to 135DEG C are flat in appearance and smooth in side surface and reach an ideal state; a die-cutting machine platform and a product die are replaced with high-temperature resisting materials, so the problem of deformation caused by expansion with heat and contraction with cold is avoided; potential hazards that the appearance of the products is influenced and the skin of a user is scratched due to the fact that the edges of patterns on a PP sheet outer frame and inner sides are rough and barbed due to adopting the conventional stamping method are eliminated; the process is simple and reasonable; the produced drawing sheet is attractive and smooth in appearance and safe and environment-friendly in use.

Description

technical field [0001] The invention relates to a drawing stationery, in particular to a method for making a drawing sheet, which is suitable for intellectual development such as drawing of children and adolescents. Background technique [0002] Children are the future of the motherland, and they need to learn certain knowledge during their growth. Painting is the second language in the process of children's growth. Through painting, children can give full play to their imagination and stimulate their potential. Books, picture albums and other school supplies are processed through the printing industry. At present, the drawing pictures used for children's intelligence development on the market are generally processed by normal temperature stamping processing methods, and there are common phenomena such as lack of materials, shrinkage, rough edges and barbs on the outer frame of the drawing picture and the inner pattern, which is not only serious. It affects the appearance ...
