Problems solved by technology

The above-mentioned process has the following disadvantages: first, the end-to-end connection of long strips of fluororesin film will inevitably form a joint seam, and the edge will be unevenly stressed and easy to disengage, which requires high technology and affects the appearance; second, During the hemming process, wrinkles will inevitably form on the edge of the fluororesin-coated fabric. If it is a round fluororesin-coated fabric, there will be many wrinkles. These wrinkles waste fluororesin raw materials and affect the appearance of the product.

Embodiment 1

[0037] Example 1: Reference Figure 1 to Figure 5 As shown, the fluororesin seamless film sealing method in this embodiment includes the following steps:

[0038] ①Put the fluororesin raw material into the mold. The fluororesin raw material is added with a color agent with a mass percentage of 1-5%. The color agent is high temperature resistant and has the same color as the fluororesin coating base cloth. It can be obtained by one of the following methods: Cylinder 1, see figure 1 Shown:

[0039] The first one is to hold the pressure, demould, and finally sinter the molded casting. The nominal pressure of the hold is 200-300kg / cm 2 ;

[0040] The second type is mechanical injection;

[0041] The third type is mechanical vulcanization;

[0042] ② Cut the obtained cylindrical body 1 into a ring 3, the axial thickness of the ring 3 after cutting is 0.1-0.3 mm, and cut an annular gap 31 on the inner wall of the ring 3, see image 3 shown;

[0043] ③Cut the fluororesin coate...

Embodiment 2

[0047] Example 2: Reference Image 6 , Figure 7 with Figure 8 , the fluororesin seamless film edge sealing method in the present embodiment comprises the following steps:

[0048] ①Put the fluororesin raw material into the mold. The fluororesin raw material is added with a color agent with a mass percentage of 1-5%. The color agent is high temperature resistant and has the same color as the fluororesin coating base cloth 2. Get barrel 1:

[0049] The first one is to hold the pressure, demould, and finally sinter the molded casting. The nominal pressure of the hold is 200-300kg / cm 2 ;

[0050] The second type is mechanical injection;

[0051] The third type is mechanical vulcanization;

[0052] ② Cut the obtained cylindrical body 1 into a ring 3, the axial thickness of the ring 3 after cutting is 0.1-0.3 mm, see Image 6 shown;

[0053] ③Cut the fluororesin-coated base cloth 2 into a shape suitable for the ring 3, and then place the cut fluororesin-coated base cloth 2...

Abstract

A fluorine resin seamless film edge packaging method is characterized by including the following steps: 1, adding the fluorine resin raw material in a mold, obtaining a tubular body by one of the following modes: firstly, pressure maintaining, mold stripping and finally sintering the compression molding cast, secondly, mechanical injection; thirdly, mechanical sulfuration; 2, cutting the obtained tubular body into a ring, and cutting a ring crack on the inner wall of the ring; 3, cutting the fluorine resin coated backing into a shape adapting to the ring, and then inserting in the crack of the ring; 4, obtaining the seamless wrapped fluorine resin coated backing after heat pressing. Compared with the prior art, the advantages of the present invention lie in that: there is no connection seam after wrapping, the wrapping has uniform force and is difficult to come away, the invention has lower process requirements; simultaneously crumple will not occur, and the products has comparatively aesthetic overall appearance without seams, crumples and junctions.

Description

technical field [0001] The invention relates to a method for sealing and wrapping a seamless film, in particular to a method for sealing and wrapping a fluororesin seamless film. Background technique [0002] Most of the cooking utensils used in the cooking industry in European and American countries are fluororesin (Teflon) pans and non-stick pans that adopt metal product coatings. The use of natural gas or gas in cooking food heating is very easy to cause the bottom of the pot to be overheated and burn out the non-stick fluororesin coating (Teflon) to produce toxic gas, cause food poisoning, affect people's health, and be burned out The pot can not be reused to bring waste of resources and environmental impact. On the other hand, with the rapid development of baking household appliances, it is more convenient for people to cook food, such as microwave ovens, toaster ovens, electric ovens and so on. In order to achieve more hygienic, less time-saving, easier to clean, mor...
