Problems solved by technology

[0004] In order to solve the above-mentioned problems, the present invention provides a method for pretreatment of raw materials of plastic cling film, which can solve the problem that heating while stirring will cause plastic particles to start to undergo hot-melt treatment without sufficient mixing, which reduces the mixing efficiency, and due to stirring There are a large number of plastic particles in the liquid, and some plastic particles have not been fully melted, so that some residual particles are mixed in the hot melt after hot melting, resulting in the reduction of hot melt efficiency and other problems.

Embodiment Construction

[0036] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] Such as Figure 1 to Figure 7Shown, a kind of pretreatment method of raw material of plastic cling film, it has used a kind of hot-melt stirring equipment, and this hot-melt stirring equipment comprises frame body 1, annular heating plate 2, mixing hot-melt device 3, blowing device 4, stirring Device 5, using the above-mentioned hot-melt stirring equipment to pretreat the raw material of plastic cling film as follows:

[0038] S1. Quantification: Quantify different types of plastic particles sequentially, and put the quantified plastic particles into the installation frame 31...

Abstract

The invention provides a pretreatment method for raw materials of a plastic fresh-keeping film. A frame body, an annular heating plate, a mixed hot melting device, a blowing device and a stirring device are matched to complete the operation, and the method can solve the problems that plastic particles begin to perform hot melting treatment without thorough mixing due to the fact that stirring andheating are simultaneously performed during existing hot melting and stirring, the mixing efficiency is reduced, and a part of the plastic particles are not subjected to sufficient hot melting due toa large amount of stirred plastic particles, so that part of the residual particles are mixed in a hot melt fluid after hot melting, the hot melting efficiency is reduced and the like.

Description

technical field [0001] The invention relates to the technical field of plastic cling film treatment, in particular to a method for pretreatment of plastic cling film raw materials. Background technique [0002] Preservative film is a kind of plastic packaging product. It is widely used in food packaging fields such as microwave oven food heating, refrigerator food preservation, fresh and cooked food packaging, etc., in family life, supermarkets, hotels and restaurants, and industrial production. Hot-melt stirring is required in the processing of film raw materials. Traditional hot-melt stirring usually heats and stirs plastic particles at the same time, but this processing method often encounters some problems: [0003] Heating while stirring will cause the plastic particles to start heat-melting treatment without being fully mixed, which reduces the mixing efficiency, and due to the large number of plastic particles in the stirring, some plastic particles have not been full...
