[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Example: See Figures 1 to 7 According to an embodiment of the utility model, a technical solution is provided: a material stirring device with a scraper spiral mixing type stirring rod group, comprising: a main frame body 1, a stirring container and a stirring rod group, wherein a feed port 2 is provided on the top of the main frame body 1; the stirring container is fixedly installed in the main frame body 1, comprising a stirring bin body 3, a bin door 4, a hinge 5 and a control cylinder 6, the feed port 2 is connected to the stirring bin body 3, the bin door 4 is hinged to the bottom of the stirring bin body 3 through the hinge 5, and the bin door 4 is controlled to open and close by the control cylinder 6 installed in the stirring bin body 3; the stirring rod group comprises a reduction motor 7, a shaft 8, an inner spiral blade 9 and a plurality of outer scrapers 10, the shaft 8 is rotatably connected in the stirring bin body 3 and driven by the reduction motor 7 fixed on the main frame body 1, the inner spiral blade 9 is fixed to the shaft 8, and the plurality of outer scrapers 10 are spaced apart along the axial direction of the shaft 8, each outer scraper 10 has a scraper end and a rod end, the rod end is fixed to the shaft 8, and the scraper end scrapes the material in the counterclockwise direction.
[0030] By using the material stirring device with the above-mentioned scraper spiral mixing stirring rod group, the material to be mixed can be put into the stirring bin body 3 along the feed inlet 2, and the shaft 8 is driven to rotate by the reduction motor 7, thereby driving the inner spiral blade 9 and multiple outer scrapers 10 to rotate counterclockwise, so that the inner spiral blade 9 drives the material in the stirring bin body 3 to move axially during the stirring process, and the material is quickly mixed by multiple outer scrapers 10, which solves the problem in the prior art that it is difficult to drive the material to move axially and mix and stir during the stirring process, and the stirring is uneven.
[0031] In this embodiment, in order to improve the mixing uniformity and prevent the material from piling up in a certain direction, two outer scrapers 10 adjacent to each other along the axial direction of the shaft 8 are arranged in an eight-shaped structure, so that during the stirring process, the outer scrapers 10 can stir the material more evenly.
[0032] In this embodiment, in order to facilitate the simultaneous feeding of different materials, a first collecting hopper 11 and a second collecting hopper 12 are provided at the feed inlet 2 on the top of the frame.
[0033] In this embodiment, a weighing bin 13 is further provided between the mixing bin and the feed port 2 in the main frame body 1. The material can enter the weighing bin 13 along the first collecting hopper 11 and the second collecting hopper 12, and be weighed and measured in the weighing bin 13. After the proportioning is completed, the material enters the mixing container. It should be noted that most of the existing mixing devices are provided with a weighing bin 13, which is generally composed of a weighing sensor and a bin door 4 whose opening and closing is controlled by a cylinder. This is a prior art, so it will not be described in detail here.
[0034] In the present embodiment, in order to prevent the material from falling directly into the weighing bin 13 along the feed port 2 and affecting the weighing and measurement of the weighing bin 13, a buffer bin 14 is provided in the main frame body 1, and the shape of the buffer bin 14 is set to be funnel-shaped, with its larger opening end facing and connected to the feed port 2, and its smaller opening end facing and connected to the weighing bin 13. In the process of the material falling into the weighing bin 13 along the feed port 2, most of the material can first fall into the buffer bin 14. In the process of the material contacting with the buffer bin 14, most of the gravity is buffered. Then the material falls into the weighing bin 13 along the smaller end of the buffer bin 14 to prevent the material from affecting the weighing and measurement of the weighing bin 13 when falling.
[0035] In this embodiment, a temporary storage barrel 15 and a suction box 16 are fixedly installed at the bottom of the main frame 1. The stirred material can be temporarily accumulated in the temporary storage barrel 15 and then sucked away through the suction box 16. The suction box 16 can be a suction box 16 directly purchased on the market. This is the existing technology, so it will not be described here.
[0036] In this embodiment, a polyfluoroethylene sleeve 17 is installed at the rotation connection between the shaft 8 and the mixing bin body 3. The polyfluoroethylene sleeve 17 has good high temperature resistance and a very low friction coefficient, which can reduce the wear of mechanical parts and energy consumption.
[0037] Working principle: different materials are poured into the first collecting hopper 11 and the second collecting hopper 12. Different materials are buffered by the buffer bin 14 and then fall into the weighing bin 13 for weighing and metering. After the proportioning is completed, they fall into the mixing bin body 3 from the top of the mixing container. The reduction motor 7 is started by the program control. The reduction motor 7 drives the shaft 8 to rotate counterclockwise to stir the materials. The materials tumble during the stirring process and are mixed along the axial movement of the shaft 8. In addition, the two groups of adjacent scrapers are in an eight-shaped structure, so that the materials will not accumulate in a certain direction. In this way, the mixing efficiency is greatly improved and the mixing effect is better. After the stirring and mixing is complete, the control cylinder 6 below the mixing bin body 3 drives the bin door 4 to open, and the materials fall into the buffer barrel and are then sucked away through the suction box 16.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
