Embodiment 1

[0036] The product adopts a cup product, including a cup body 29, three first accommodating cavities 30 arranged on the outer wall of the cup body 29, and a sealing cover 31 arranged on the outer wall of the cup body 29 and used for sealing the first accommodating cavities 30 .

[0037] A method of recycling and sorting plastic products that relies on built-in structures, the specific steps are as follows:

[0038] 1) When designing the product, add a built-in structure inside the product; during the production process of the product, inject different color dyes into the built-in structure according to the recycling characteristics of the product material, and seal the built-in structure;

[0039] 2) Recycle the waste products of the above-mentioned products after use, and clean and dry them;

[0040] 3) Put the waste products into the feeding hopper of the dyeing pulverizer, and the waste products fall into the corresponding crushing channels of different sizes along the par...

Embodiment 2

[0049] The product adopts a box product, including a box body 32, a second accommodating cavity 33 arranged around and at the bottom of the box body 32, and a sealing plug 34 arranged around and at the bottom of the box body 32 and used for sealing the second accommodating cavity 33 There are four second accommodating cavities 33 at the bottom of the box body 32, which are centrally symmetrically distributed, and each of the four side walls of the box body 32 has a second accommodating cavity 33, which are centrally symmetrically distributed .

[0050] The dyeing pulverizer includes a shell, a feeding hopper 1 arranged on the top of the casing, a partition plate 2 arranged below the feeding hopper 1, a group of crushing passages arranged on the periphery of the partition plate 2, and a group of crushing channels arranged under the partition plate 2 and extending The cutting device in the crushing channel, the crushing channel adopts a ring structure and is provided with three ...

Abstract

The invention discloses a method for recycling plastic products by virtue of a built-in structure. The method for recycling plastic products by virtue of the built-in structure comprises the followingsteps that 1) when the product is designed, a built-in structure is added into the product; and coloring agents with different colors are injected in the built-in structure in the product productionprocess according to the product material recovery characteristic, and sealing processing is carried out on the built-in structure; 2) the waste products are recycled after the products are used, andcleaning and drying is carried out; and 3) the waste products are put into a feeding hopper of a dyeing pulverizer, the waste products fall into corresponding crushing channels with different sizes along the partition plates and is cut by the cutting device, when the cutting device is cut into the built-in structure filled with the coloring agent, and the dyeing agent can be sprayed out of the built-in structure to dye the waste products. The method has the beneficial effects that the built-in structure is not prone to being worn in use, so that the product recovery and classification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of recycling and sorting waste plastic products, and specifically relates to a method for recycling and sorting plastic products by means of a built-in structure. Background technique [0002] The recycling of plastic waste has always been an important issue in environmental protection. However, most plastic products are not designed with recycling in mind. Instead, after the product is designed, it is processed on the product, such as attaching an electronic identification label. However, this kind of treatment can only be done on the surface of the product, which will affect the appearance of the product. At the same time, it is easy to be damaged during use, making it impossible to identify the type of plastic during recycling. Therefore, the present invention proposes a method for recycling and sorting plastic products relying on built-in structures. The above-mentioned problems are avoided by the bui...
