Three-dimensional packing machine and sealing system thereof

Abstract

The invention discloses a three-dimensional packing machine and a sealing system thereof. Built-in heating pipes of an upper sealing film of a sealing system are in a dislocation distribution mode, thereby effectively compensating the phenomenon of uneven heat generation of a plate surface for the uneven arrangement of heating pipes. In the three-dimensional packing machine, the defective rate of sealing package is greatly reduced, the packing quality of products is greatly increased, the packing pass rate is increased, the unnecessary waste of film materials is avoided in production, and the production cost is reduced.

Description

【Technical field】 [0001] The invention relates to a forming mold for automatic forming and packaging of packaging materials, a sealing mold, and mechanical equipment capable of automatic packaging, coding and cutting of various products. 【Background technique】 [0002] In the prior art, products in various industries such as pharmaceuticals, health care products, food, cosmetics, and agricultural products need to be packaged. The packaging machine can heat-seal, pack, and count. And the forming machine can form various plastic film materials, such as PE, PP, PS, ABS, etc., into various beverage cups, convenient bowls (boxes), trays, preserved fruit covers, industrial and agricultural product packaging, and various Class plastic packaging containers, providing packaging machines with the above-mentioned product packaging containers. In the packaging production of products, the above-mentioned processes are relatively independent, the production efficiency is low, and it is ...

Problems solved by technology

[0003] In the prior art blister forming machine or sealing packaging machine, since the heating plate and the sealing upper mold are heated by the built-in heating rod, due to the arrangement of the heating rod, the distance between each area of ​​the working surface and the heating element is different, The temperature difference of each detection point on the working surface is relatively large, resulting in uneven preheating of the membrane material, resulting in poor molding and sealing

like Image 6 As shown, the heating plate in the prior art adopts the whole plate preheating method. After the heating plate closes the mold, the film material in the middle of the heating plate is heated, while the film material in the back is not heated, and it is heated in the previous step. There is a wrinkle between the membrane material and the heating membrane material in the next step. In fact, this wrinkle is caused by the edge of the whole heating plate.

During the sealing process, it is not 100% guaranteed that this wrinkle will be included in the sealing area. When the wrinkle in this area is just on the sealing edge of the packaging container and the upper film, the upper film will be sealed during sealing. The seal is pressed on the wrinkle, resulting in poor sealing or leakage, which seriously affects the production quality

Since the edge of the film material is not sealed during sealing, the upper film material and the lower film material are not sealed and pressed together, and the waste edge after the product is cut is very scattered, making it difficult to collect
