DETAILED DESCRIPTION

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] like Figure 1 As shown, the present application provides an extrusion granulator mixing and feeding device, comprising an extrusion granulator 1, which is arranged in a plastic processing plant and is used to extrude plastic particles. At the same time, an opening is provided at the top of the extrusion granulator 1, and a feeding component 2 is provided at the opening;

[0027] like Figure 2-Figure 4As shown, the feeding assembly 2 includes a connecting frame 21, which is fixedly mounted on one side of the extrusion granulator 1. At the same time, a hopper 22 is fixedly mounted on the top of the connecting frame 21. A partition 23 is provided inside the hopper 22. The partition 23 divides the interior of the hopper 22 into two groups of feeding areas. At the same time, two groups of discharge ports 24 are provided at the bottom of the hopper 22. The discharge ports 24 correspond to one group of feeding areas respectively. When feeding is required, if only one type of plastic particles is required for current production, one of the feeding areas can be selected for filling. If different types of plastic particles need to be mixed, different materials can be added to the two feeding areas at the same time. Due to the presence of the partition 23, the materials in different feeding areas will not mix with each other.

[0028] At the same time, a proportioning component 3 is provided at the bottom of the hopper 22. The proportioning component 3 includes a connecting plate 31. The connecting plate 31 is provided with two sets of feed ports 311 adapted to the positions of the discharge ports 24. At the same time, two sets of proportioning boxes 32 are provided at the bottom of the connecting plate 31. The proportioning boxes 32 are used to receive different materials entering the hopper 22. At the same time, in order to make the falling of the materials smoother, part of the position inside the proportioning boxes 32 is set as an inclined surface. When the materials fall, they will roll down along the inclined surface.

[0029] A clamping column 33 is provided at the bottom of the proportioning box 32. A chute is provided in the clamping column 33, and a baffle 35 is slidably installed in the chute. The baffle 35 is used to block the material in the proportioning box 32.

[0030] A transparent observation window 4 is provided on the outside of the proportioning box 32, and a scale mark 41 is provided on the observation window 4. The scale mark 41 is used for the staff to observe the quantity and status of the materials in the proportioning box 32 in real time;

[0031] At the same time, a cylinder 34 is provided on the connecting frame 21 on one side of the proportioning box 32. The output end of the cylinder 34 is connected to the baffle 35 to control the opening and closing of the baffle 35, and a weighing sensor 36 is provided at the bottom of the two groups of proportioning boxes 32. The weighing sensor 36 has a receiving head, and the receiving head is connected to the bottom of the proportioning box 32. The weighing sensor 36 is used to weigh the materials stored in the proportioning box 32 to confirm the weight of different materials in the proportioning box 32.

[0032] like Figure 2 、 Figure 5 As shown, a pre-mixing box 5 is provided at the bottom of the two groups of proportioning boxes 32. The top of the pre-mixing box 5 is connected to the bottom of the two groups of proportioning boxes 32. At the same time, two groups of motors 51 are fixedly installed on both sides of the pre-mixing box 5, and a distribution wheel 52 is fixedly installed on the output end of the motor 51. The distribution wheel 52 is suitable for rotating under the drive of the motor 51, and the distribution wheel 52 has multiple groups of blades.

[0033] When adding materials, the materials will fall directly from the proportioning box 32 into the pre-mixing box 5. At this time, the materials will first contact the two sets of distribution wheels 52 in the pre-mixing box 5 and be broken up by the rotation of the distribution wheels 52, making them more evenly distributed. The two sets of broken materials will then be reassembled and enter the extrusion granulator 1 from the bottom of the pre-mixing box 5, preventing the materials from entering and avoiding local excessive concentration, thereby improving the granulation effect.

[0034] To sum up, when adding materials is required, different types of materials are first passed through the hopper 22 into the two groups of proportioning boxes 32 respectively, and then the weighing sensor 36 and the observation window 4 are set, so that the staff can more accurately control the amount of materials entering the pre-mixing box 5. At the same time, through the design of the pre-mixing box 5, the material reaches a better mixed state before entering the extrusion granulator 1, reducing the mixing burden inside the extrusion granulator 1, which is conducive to improving the overall production efficiency.

[0035] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
