[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, a putty powder rapid proportioning device includes a mixing tank 1, and a plurality of raw material metering and discharging mechanisms 2 are fixedly connected to the upper side of the mixing tank 1. When the raw materials enter the raw material metering and discharging mechanisms 2, the raw materials can be transported into the interior of the mixing tank 1 by the raw material metering and discharging mechanisms 2, thereby improving the efficiency of raw material proportioning;

[0023] The lower end of the mixing tank 1 is fixedly connected with a discharge pipe, and a valve is fixedly connected to the discharge pipe.

[0024] Among them, one structure of the raw material metering and unloading mechanism 2 is a raw material tank fixedly connected to the upper side of the stirring tank 1, and the lower end of the raw material tank and the upper end of the stirring tank 1 are connected by a connecting pipe. The raw material inside the raw material tank can automatically fall into the stirring tank 1 through the connecting pipe under the action of gravity. An electromagnetic valve is installed on the connecting pipe to achieve the purpose of controlling whether the raw material inside the connecting pipe can be unloaded. A weighing device is also installed inside the raw material tank to weigh the raw material inside the raw material tank. A controller is fixedly connected to the outside of the raw material tank. The weighing device and the electromagnetic valve are electrically connected to the controller. When unloading, the raw material inside the raw material tank is weighed by the weighing device. When the raw material inside the raw material tank is reduced to a set amount, the controller controls the electromagnetic valve to close.

[0025] The raw material metering and unloading mechanism 2 can also be a metering feeder for putty powder production disclosed in Chinese patent publication number CN 209155773 U.

[0026] The core of this technical solution is that the upper end of the mixing tank 1 is fixedly connected to a servo motor 3, and the output end of the servo motor 3 is rotatably connected to a rotating shaft 4 located at the center of the mixing tank 1. The outer side of the rotating shaft 4 is equipped with multiple stirring elements with electrically adjustable heights. At this time, when the raw material metering and feeding mechanism 2 feeds the inside of the mixing tank 1, the height of the stirring element can be adjusted according to the height of the raw material inside the mixing tank 1, so that the stirring element is always located inside the raw material to stir the raw material.

[0027] The height adjustment method of the stirring element can be adjusted independently by multiple vertical moving devices, or can be adjusted as a whole by one vertical moving device. In this technical solution, the electric push rod 12 is preferably used as the vertical moving device to adjust the multiple stirring elements as a whole;

[0028] like Figure 1-3As shown, the stirring piece at the bottom is fixedly connected to the outside of the rotating shaft 4, and the other stirring pieces are vertically slidably connected to the outside of the rotating shaft 4. A return spring 14 is fixedly connected between two adjacent stirring pieces, and an electric push rod 12 is fixedly connected to the upper side of the mixing tank 1. The piston rod of the electric push rod 12 is fixedly connected to a pressure plate 13 located on the upper side of multiple stirring pieces. The pressure plate 13 is vertically slidably connected to the outside of the rotating shaft 4. At this time, the pressure plate 13 can be driven to move by starting the electric push rod 12. When the pressure plate 13 moves downward, it will press down on multiple stirring pieces to lower the height of the stirring pieces. When the electric push rod 12 drives the pressure plate 13 to move upward, the stirring piece will move upward under the elastic force of the return spring 14, so that the height of the stirring piece can be electrically adjusted.

[0029] Specifically, the stirring member includes a sliding ring body 5 that is vertically slidably connected to the outside of the rotating shaft 4. A locking screw is threadedly connected to the sliding ring body 5 at the bottom. When the locking screw and the rotating shaft 4 are abutted, the sliding ring body 5 at the bottom and the rotating shaft 4 can be fixed together. The outside of the sliding ring body 5 is equipped with a rotating drive group and a stirring piece. The stirring piece is rotatably connected to the outside of the sliding ring body 5, and the rotating drive group and the stirring piece are transmission-connected. At this time, by driving the stirring piece to revolve on the rotating shaft 4 while driving the stirring piece to rotate on its own through the rotating drive group, the stirring effect of the stirring piece on the proportioning of the raw materials can be effectively improved.

[0030] Among them, such as Figure 2-4 As shown, the outer side of the sliding ring body 5 is rotatably connected to two stirring blades, and the stirring blade includes a rotating rod 6 rotatably connected to one side of the sliding ring body 5 and arranged horizontally. The rotating rod 6 is transmission-connected to the rotating drive group, and a spiral blade 7 is fixedly connected to the outer side of the rotating rod 6. When the rotating rod 6 rotates, the spiral blade 7 is driven to rotate, and the two spiral blades 7 can be symmetrically arranged, so that the two spiral blades 7 can drive the raw materials to move in opposite directions, thereby better stirring the raw materials.

[0031] like Figure 2-4 As shown, the rotary drive group includes a rotating frame 9 rotatably connected to the outside of the sliding ring body 5 and located at the lower side of the spiral piece 7. The outer side of the rotating frame 9 is fixedly connected to an annular piece 10, and the outer side of the annular piece 10 is fixedly connected to a slider 11. A slide groove is provided on the inner wall of the mixing tank 1, and the slider 11 is vertically slidably connected to the inside of the slide groove, so that the annular piece 10 can move up and down synchronously with the sliding ring body 5 as much as possible, and cannot rotate. The end of the rotating rod 6 away from the sliding ring body 5 is fixedly connected to the runner 8 located on the upper side of the annular piece 10. When the sliding ring body 5 drives the runner 8 to revolve, the runner 8 will move on the annular piece 10, and the runner 8 will rotate when it moves, inputting rotational kinetic energy to the rotating rod 6 and the spiral piece 7.

[0032] Here, the height of the raw materials inside the mixing tank 1 can be measured by an infrared distance measuring device, or a vertical transparent observation window can be provided on the side wall of the mixing tank 1 for direct observation.

[0033] The working principle of this utility model is:

[0034] The raw materials are fed into the mixing tank 1 through multiple raw material metering and feeding mechanisms 2, and then the electric push rod 12 is activated according to the height of the raw materials in the mixing tank 1 to adjust the height of the multiple stirring elements so that the stirring elements are always located inside the raw materials;

[0035] After the height adjustment of the stirring element is completed, the servo motor 3 is started to drive the stirring element to rotate and stir the raw materials.

[0036] In summary, this technical solution adjusts the heights of multiple stirring elements according to the feed amount of raw materials so that the stirring elements are always located inside the raw materials. All stirring elements can be used to stir the raw materials, thereby improving the efficiency of raw material proportioning and stirring.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
