[0026] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present application and with reference to the accompanying drawings.

[0027] As Figure 1-2 shown, a mixing and feeding device for modified plastic particles includes: a mixing assembly 1, a feeding assembly 2, and a connecting pipe 3; the feeding assembly 2 provides different plastic particle raw materials for the mixing assembly 1 through the connecting pipe 3;

[0028] The mixing component 1 includes: a cylindrical bin 101, a conical bin 102, and an upper cover 103. The conical bin 102 is arranged at the lower part of the cylindrical bin 101, and the upper cover 103 is arranged at the upper part of the cylindrical bin 101. A mixing motor 104 and a first feed inlet 106 are arranged on the upper surface of the upper cover 103. The first feed inlet 106 is communicated with the connecting pipe 3. The output end of the mixing motor 104 extends below the upper cover 103 and is fixedly connected with a rotating shaft 105 through a coupling 113. The rotating shaft 105 is successively provided with a first mixing plate 108 and a second mixing plate 109 from top to bottom. A first discharge port 107 is opened at the lower end of the conical bin 102. The arrangement of the first mixing plate 108 and the second mixing plate 109 can increase the moving distance of plastic particles during the falling process and improve the uniformity of mixing of different plastic particles. And by driving the first mixing plate 108 and the second mixing plate 109 to rotate through the mixing motor 104, the mixing rods 110 on the mixing plates can mix different plastic particles in the circumferential direction, further ensuring the uniformity of mixing of different plastic particles by the mixing component.

[0029] As Figure 2-3 shown, the first mixing plate 108 and the second mixing plate 109 are two symmetrically arranged conical plates. The sides with smaller diameters of the two conical plates are adjacent. A plurality of mixing rods 110 are respectively arranged on the upper surfaces of the first mixing plate 108 and the second mixing plate 109. Sleeves 111 are respectively arranged in the middle parts of the first mixing plate 108 and the second mixing plate 109. The sleeves 111 are used to cooperate with the rotating shaft 105. A plurality of second discharge ports 112 are opened at the lower part of the first mixing plate 108. Through the shape setting of the first mixing plate 108 and the second mixing plate 109, plastic particles can move by their own weight to form vertical movement, and collide with the mixing rods 110 during the movement for preliminary mixing. Driving the mixing plates to rotate by the mixing motor 104 can further mix the plastic particles, ensuring the uniformity of mixing of different plastic particles.

[0030] As Figure 2 shown, the first feed inlet 106 is located above the first mixing plate 108, facilitating the falling of plastic particles into the first mixing plate 108. The edge of the second mixing plate 109 is spaced from the inner wall of the cylindrical bin 101. The mixed plastic particles enter the conical bin 102 through the space and then enter the downstream processing equipment from the first discharge port 107 below the conical bin 102.

[0031] As Figure 4 shown, the feeding component 2 includes: a weighing bin 201, a feeding bin 202, and a plurality of feeding valves 204;

[0032] The feed bin 202 is arranged above the weighing bin 201. A plurality of second feed inlets 203 are formed in the upper side wall of the feed bin 202. A feed valve 204 is correspondingly arranged at each second feed inlet 203. A feed pipe 205 is arranged above the feed valve 204. The feed pipe 205 is used for connecting the plastic particle raw material bin. A third discharge outlet 209 is arranged at the lower part of the weighing bin 201. The third discharge outlet 209 is used for communicating with the connecting pipe 3. A weighing assembly is arranged inside the weighing bin 201. The feeding of different plastic particles is realized by opening and closing the feed valve 204.

[0033] As Figure 4 shown, the weighing assembly includes: a turning plate 206, a load plate 208, a turning motor 207 and a controller. The inner cavity of the weighing bin 201 is spherical. The turning plate 206 is rotatably connected to the middle of the weighing bin 201. A turning motor 207 is fixedly connected to one side of the weighing bin 201. The turning motor 207 is used to drive the turning plate 206 to turn; a load plate 208 is arranged on the upper surface of the turning plate 206. A pressure sensor is arranged between the load plate 208 and the turning plate 206;

[0034] The controller is electrically connected to the turning motor 207, the pressure sensor and a plurality of feed valves 204 respectively.

[0035] Working principle: The user can read the reading of the pressure sensor through an external display device. After the feed valve 204 is opened, the plastic particles fall onto the load plate 208 inside the weighing bin 201. The weight of the plastic particles is obtained by the pressure sensor and displayed through the external display device; First, according to the ratio of different plastic particles, determine the weight of different plastic particles in each portion of the raw material. By adjusting the opening time of the feed valve 204, the plastic particles of corresponding weight are put in. After adjusting the opening time required for each feed valve 204, the feeding assembly 2 can realize the quantitative feeding of different plastic particles. The above adjustment process is carried out through the controller;

[0036] Specific working steps: First, the turning plate 206 is in a horizontal state, and the upper and lower parts of the weighing bin 201 are separated. The controller controls the corresponding feed valve 204 to open for a set time. Different plastic particles enter the weighing bin 201. After all the feed valves 204 have finished feeding, the turning motor 207 drives the turning plate 206 to turn. The plastic particles enter the mixing assembly through the connecting pipe 3 for mixing and are conveyed to the downstream processing equipment.

[0037] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
