DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] Example:

[0028] like Figure 1 - Figure 5 As shown, the present invention provides a technical solution of a raw material mixing device for producing plastic products:

[0029] As shown in the figure, a raw material mixing device for producing plastic products, the structure of which includes a mixing tank body 1, a support frame 2 for supporting the mixing tank body 1, a feed port 3 located on the upper surface of the mixing tank body 1, a stirring structure 4 arranged inside the mixing tank body 1, a discharge port 5 arranged at the lower part of the front surface of the mixing tank body 1 and a transmission motor 6 located on the lower surface of the mixing tank body 1 and connected to the stirring structure 4, the stirring structure 4 includes a stirring rod 41 which is vertically arranged and the end of which is matched with the transmission motor 6, an upper stirring plate 42 located at the top end of the stirring rod 41 and a scraping mechanism 43 located at the lower part of the stirring rod 41 and in contact with the lower part of the mixing tank body 1, the scraping mechanism 43 includes a matching frame 431, two star gears 432 which are symmetrically installed inside the matching frame 431, and a gear 432 located inside the matching frame 431. A shaft sleeve 433 in the middle that meshes with the movable frame 431 through a star gear 432, a positioning sleeve frame 434 having three pieces that are evenly and equidistantly installed on the outer surface of the movable frame 431, a slide slot frame 435 opened in the positioning sleeve frame 434, a slider 436 located in the slide slot frame 435, a limit spring 437 arranged in the slide slot frame 435 and connected to the slider 436, a movable plate 438 with one end extending into the slide slot frame 435 and connected to the slider 436, an arc plate 439 arranged at the other end of the movable plate 438, a matching strip 4310 arranged on the surface of the arc plate 439 and installed toward one side of the movable plate 438, a spring ring 4311 arranged on the other side of the arc plate 439 and a scraper strip 4312 located on the lower surface of the positioning sleeve frame 434 and in contact with the lower wall of the mixing tank body 1.

[0030] The shaft sleeve 433 is fitted with the end of the stirring rod 41 and moves synchronously during operation.

[0031] The interior of the positioning sleeve 434 is a hollow structure and cooperates with the movable plate 438 to facilitate the scraping of the sinking raw materials during the rotation process.

[0032] There are five spring rings 4311 which are evenly and equidistantly arranged, which is beneficial for scraping off the raw materials attached to the lower surface of the mixing tank body under the contact and dynamic elasticity of the spring rings.

[0033] The length of the scraper bar 4312 is smaller than the inner radius of the mixing tank body 1, and the end thereof is in contact with the inner wall of the mixing tank body 1, which is conducive to rotary scraping of the raw materials that sink to the bottom.

[0034] The matching strip 4310, the spring ring 4311 and the scraping strip 4312 are all made of smooth stainless steel, so as to prevent the materials that have sunk to the bottom from adhering to the surface again after being scraped by these three components.

[0035] The transmission motor 6 is provided with a control switch.

[0036] The specific implementation principle is as follows: the raw materials of the plastic products to be mixed are poured into the mixing tank body 1 through the feed port 3, and the transmission motor 6 is turned on to make the stirring rod 41 connected thereto rotate, thereby stirring the raw materials in the mixing tank body 1 to mix them with each other. Since the shaft sleeve 433 cooperates with the stirring rod 41, it rotates synchronously with it. The matching frame 431 rotates in the opposite direction under the interaction of the star gear 432 and the shaft sleeve 433. Under the rotation of the matching frame 431, the movable plate 438 is thrown out from the inside of the positioning sleeve frame 434 to the outside, so that the arc plate 439 and the spring ring 4311 contact the inner wall of the mixing tank body 1, thereby having a scratching effect on the raw materials attached to the inner wall, and under the action of the spring ring 4311's own elasticity, the raw materials attached to its surface can be shaken off;

[0037] The scraper bar 4312 rotates synchronously with the positioning sleeve frame 434 under the rotation action, thereby scraping the raw materials on the lower surface of the mixing tank body 1. When the scraping mechanism and the stirring rod move in the opposite direction, the scraped raw materials are turbulently mixed, thereby achieving uniform and effective mixing of the raw materials.

[0038] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
