DETAILED DESCRIPTION

[0027] The present disclosure will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

[0028] In order to make the drawing simple, only the parts related to the disclosure are shown in each figure, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some figures, only one of the parts with the same structure or function is shown, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0029] In this paper, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0030] In the present disclosure, unless otherwise specified and limited, the "upper" or "lower" of the first feature to the second feature can include the direct contact of the first and second features, or the contact of the first and second features through another feature between them. Moreover, the "upper", "upper" and "upper" of the first feature to the second feature include the vertical and oblique above of the first feature to the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-4 As shown, it illustrates an electrostatic sorting machine for cleaning plastic sheets according to an embodiment of the present disclosure, including: a pair of base frames 1 and a feed box 2, the feed box 2 being fixed on the base frames 1;

[0034] Crushing component 4 is installed inside the feed box 2;

[0035] Separation component 3 is located inside the feed box 2;

[0036] Electrostatic purification component 5 is installed on the feed box 2;

[0037] The separation component 3 includes several inner frames 3-1, all of which are fixed to the inner surface of the feed box 2. A cleaning port 3-2 is provided on the side surface of the feed box 2. A flip cover 3-3 is rotatably connected to the cleaning port 3-2 through a pin. A handle 3-4 is provided on the surface of the flip cover 3-3.

[0038] In some examples, to achieve the effect of separating the rubber, a separation component 3 is designed. Multiple inner frames 3-1 are set inside the feed box 2, with gaps between them. The inner frames 3-1 can hold the rubber and separate it from the plastic. A cleaning port 3-2 is opened on one side of the feed box 2. The cleaning port 3-2 is located at the inner frame 3-1. The rubber on the inner frame 3-1 can be cleaned at the cleaning port 3-2. An outwardly opening flip cover 3-3 is installed inside the cleaning port 3-2. The surface of the flip cover 3-3 is provided with a handle 3-4, which can be operated to open the flip cover 3-3 outward.

[0039] like Figures 1-4 As shown, this embodiment proposes a crushing component 4 including a pair of crushing rollers 4-1, both of which are rotatably connected inside the feed box 2. One end of the crushing roller 4-1 is provided with a transmission gear 4-2, and one of the crushing rollers 4-1 is controlled to rotate by a motor.

[0040] In some examples, in order to achieve the effect of crushing plastic, a crushing component 4 is designed, in which two crushing rollers 4-1 are rotatably connected inside the feed box 2. One of the crushing rollers 4-1 is controlled to rotate by a motor. Both crushing rollers 4-1 are provided with a transmission gear 4-2 at one end, which can make the two crushing rollers 4-1 rotate synchronously.

[0041] like Figures 1-4 As shown, the electrostatic impurity removal component 5 includes a conveyor belt 5-1, which is arranged between the base frames 1. A bottom cover 5-2 is provided on the side surface of the feed box 2. The lower end face of the bottom cover 5-2 is slidably attached to the surface of the conveyor belt 5-1. Rectangular openings 5-3 are provided on both sides of the bottom cover 5-2. Baffles 5-4 are rotatably connected to both sides of the bottom cover 5-2 through pins. A connecting frame 5-5 is provided on the side surface of the base frame 1. A telescopic cylinder 5-6 is rotatably connected to the connecting frame 5-5 through pins. Several electrostatic frames 5-7 are provided on the side surface of the baffles 5-4. An electrostatic generator 5-8 is provided on the side surface of the base frame 1.

[0042] In some examples, to achieve the effect of separating metal particles by electrostatics, an electrostatic impurity removal component 5 is designed. A conveyor belt 5-1 is set in the frame to transport plastic outwards. A bottom cover 5-2 is set on the side surface of the feed box 2. The bottom of the bottom cover 5-2 slides against the surface of the conveyor belt 5-1, which can keep the plastic inside the bottom cover 5-2 and transport it outwards. Rectangular openings 5-3 are opened on both sides of the bottom cover 5-2. A baffle 5-4 is rotatably connected to the outside by a pin. A connecting frame 5-5 is set on one side of the base frame 1. A telescopic cylinder 5-6 is connected between the connecting frame 5-5 and the baffle 5-4. The telescopic cylinder 5-6 can pull the baffle 5-4 outwards to open the rectangular openings 5-3. An electrostatic frame 5-7 is set on the side surface of the baffle 5-4. An electrostatic generator 5-8 is set on the outside of the base frame 1 to generate static electricity in the electrostatic frame 5-7. The metal can be attracted to the electrostatic frame 5-7 by static electricity. The electrostatic frame 5-7 can be removed and cleaned by flipping it outwards through the baffle 5-4.

[0043] For example, such as Figure 1 As shown, the bottom cover 5-2 has an overall door-shaped structure.

[0044] In some examples, the gate-shaped structure gives the bottom cover 5-2 a shielding effect, keeping the plastic inside.

[0045] For example, such as Figure 1 As shown, the conveyor belt 5-1 is made of insulated rubber.

[0046] In some examples, the rubber material structure is used to prevent the conveyor belt 5-1 from generating static electricity that attracts metal, making cleaning inconvenient.

[0047] For example, such as Figure 4As shown, the cross-section of the inner frame 3-1 has a triangular structure.

[0048] In some examples, the triangular structure increases the opening size between the intervals, allowing the plastic sheets to slide in and making them easier to separate, thus preventing plastic from piling up on the inner frame 3-1.

[0049] When processing is required, the recycled plastic is put into the feed box 2, and the crushing roller 4-1 is started to crush the plastic sheets. The crushed plastic falls onto the inner frame 3-1, and the plastic is separated downwards through the intervals. The rubber will not be crushed and is larger in size, so it will get stuck on the bracket. The flip cover 3-3 can be opened to clean the rubber on the inner frame 3-1 at the cleaning port 3-2. The crushed plastic falls onto the conveyor belt 5-1 and is conveyed outwards. The electrostatic generator 5-8 is started to generate static electricity in the electrostatic frame 5-7. The static electricity attracts metal particles to the surface. After a certain amount is attracted, the telescopic cylinder 5-6 is started to open the baffle 5-4 outwards. After opening, the electrostatic frame 5-7 can be cleaned.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
