Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for putty. Background Art

[0002] Atomic putty, commonly known as putty, also known as unsaturated polyester resin putty, is a new type of filling material with rapid development. It can adhere well to the surface of objects and will not crack during the drying process. Atomic putty is a polymer material composed of two parts: main putty and curing agent. The main putty is mostly composed of unsaturated polyester resin and filler, and the curing agent is generally composed of initiator and plasticizer, which plays the role of initiating polymerization and enhancing performance. In the process of producing atomic putty, the atomic putty raw materials are generally mixed through an atomic putty raw material stirring device.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 In this embodiment, a mixing device for atomic putty includes a mixing tank 1. The top of the mixing tank 1 is provided with a mixing mechanism 2 for mixing and cleaning the atomic putty. The upper surface of the mixing mechanism 2 is provided with a proportioning mechanism 3 for automatically proportioning the atomic putty.

[0025] See also Figures 2 to 3 The bottom wall of the connecting frame 23 is fixed with a mixing motor 24, and the outer side of the output shaft of the mixing motor 24 is fixed with a stirring shaft 25. The outer side of the stirring shaft 25 is fixed with two stirring blades 26 facing in opposite directions. When the mixing motor 24 is started, the stirring shaft 25 is driven to rotate by its output shaft, and the two stirring blades 26 facing in opposite directions on the stirring shaft 25 rotate to mix the atomic ash in the tank. A cleaning component 27 is provided on the lower surface of the tank cover 21 to clean the stirring shaft 25 and the stirring blades 26.

[0026] The cleaning assembly 27 includes a cleaning frame 271 fixed to the lower surface of the tank cover 21, and cleaning air pipes 272 are fixed to the inner walls of the front and rear sides of the cleaning frame 271, and the opposite sides of the two cleaning air pipes 272 are connected to downward-inclined air knife nozzles 273. The air is transported to the cleaning air pipes 272 through the air inlet pipe 275 and the diverter pipe 274. High-pressure air is ejected from the two air knife nozzles 273 to form two air knives for cleaning the atomic ash slurry on the stirring shaft 25 and the stirring blade 26. A diverter pipe 274 is connected between the opposite sides of the two cleaning air pipes 272, and the outer side of the diverter pipe 274 is connected to the air inlet pipe 275, and the end of the air inlet pipe 275 away from the diverter pipe 274 is connected to the air pump 276. When the atomic ash raw materials are mixed in the mixing tank 1, the mixing motor 24 is stopped and the air pump 276 is started to generate high-pressure air.

[0027] In this embodiment, a controller is provided on the upper surface of the tank cover 21, a handle is fixed on the upper surface of the connecting frame 23, a sliding hole is provided in the middle of the upper surface of the tank cover 21, and the stirring shaft 25 is slidably connected along the inner wall of the sliding hole, the length of the air knife nozzle 273 is greater than the length of the stirring blade 26, and four positioning holes are provided on the lower surface of the connecting frame 23, and the connecting frame 23 is connected to the outside of the four positioning columns 22 through the four positioning holes. Use the handle to manually lift the mixing motor 24 and the stirring shaft 25. As the lifting height changes, the stirring shaft 25 and the stirring blade 26 pass through two air knives, and the attached atomic ash slurry is blown off by high-pressure air. The blown-off atomic ash slurry falls into the mixing tank 1, achieving the purpose of quick and effective cleaning without wasting the slurry.

[0028] See also Figure 4 In order to automatically proportion the atomic putty, the proportioning mechanism 3 in this embodiment includes a feed pipe 31 connected to the upper surface of the tank cover 21, a guide hopper 32 is fixed on the upper surface of the feed pipe 31, a flip plate 33 is hinged on the left side of the guide hopper 32, an electric push rod 34 is fixed on the upper surface of the tank cover 21, an electronic scale 35 is fixed in the middle of the upper surface of the flip plate 33, and a measuring tray 36 is fixed on the upper surface of the electronic scale 35. The atomic putty raw material is placed on the measuring tray 36 and accurately weighed using the electronic scale 35 to ensure the accurate amount of the required raw material. The tank cover 2 1 is connected to the right side of the upper surface thereof, and a flow valve 38 is fixed on the outside of the water adding pipe 37. The required mixing ratio information is input to the controller so as to control the amount of raw materials and water added during the mixing process. The top end of the water adding pipe 37 is connected to an external faucet to guide the water flow through the flow valve 38 into the mixing tank 1. The flow valve 38 controls the amount of water added according to the ratio. After the raw materials and water are added to the mixing tank 1, the mixing mechanism 2 is started again, so that the mixing motor 24 drives the stirring shaft 25 and the stirring blade 26 to rotate, thereby mixing the putty.

[0029] In this embodiment, a bracket is fixed to the left side of the lower surface of the flip plate 33, and a rotating shaft is rotatably connected between the front and rear inner walls of the bracket through a bearing. The outer side of the output shaft of the electric push rod 34 is fixed to the rotating shaft. After weighing is completed, the electric push rod 34 is started to extend its output shaft, raising one side of the flip plate 33 so that the ash raw material is poured into the guide hopper 32. The ash raw material enters the mixing tank 1 through the guide hopper 32 and the feed pipe 31 and is ready for mixing. A horizontal limit frame is fixed to the upper surface of the tank cover 21 and below the flip plate 33. The horizontal limit frame supports the flip plate 33 to ensure that the measuring tray 36 is placed horizontally for accurate weighing.

[0030] The working principle of the above embodiment is:

[0031] (1) Connect the tank cover 21 of the mixing mechanism 2 to the top of the mixing tank 1 through threads, ensure that the tank cover 21 is fixed and stable, ensure that the four positioning posts 22 on the tank cover 21 are in the correct position, plug the connecting frame 23 into the outside of the positioning posts 22, start the mixing motor 24, and drive the stirring shaft 25 to rotate through its output shaft. The two stirring blades 26 on the stirring shaft 25 rotate in opposite directions to mix the atomic ash in the tank. When the atomic ash raw materials are mixed in the mixing tank 1, stop the mixing motor 24 and start the air pump 276 to generate high-pressure air. The air is transported to the cleaning air pipe 272 through the air inlet pipe 275 and the diversion pipe 274. The high-pressure air is ejected from the two air knife nozzles 273 to form two air knives for cleaning the atomic putty on the stirring shaft 25 and the stirring blades 26. The mixing motor 24 and the stirring shaft 25 are manually lifted using the handle. As the lifting height changes, the stirring shaft 25 and the stirring blades 26 pass through the two air knives, and the attached atomic putty is blown off by the high-pressure air. The blown-off atomic putty falls into the mixing tank 1, achieving the purpose of quick and effective cleaning without wasting the slurry.

[0032] (2) Place the ash raw material on the metering tray 36 and use the electronic scale 35 to accurately weigh it to ensure the accurate amount of the required raw material. The horizontal limit frame supports the flip plate 33 to ensure that the metering tray 36 is placed horizontally for accurate weighing. After weighing is completed, start the electric push rod 34 to extend its output shaft and raise one side of the flip plate 33 to pour the ash raw material into the guide hopper 32. The ash raw material enters the mixing tank 1 through the guide hopper 32 and the feed pipe 31 and is ready to be mixed. Input the required mixing ratio information into the controller to control the amount of raw material and water added during the mixing process. Connect the top of the water adding pipe 37 to the external faucet to guide the water flow through the flow valve 38 into the mixing tank 1. The flow valve 38 controls the amount of water added according to the ratio. After the raw material and water are added to the mixing tank 1, start the mixing mechanism 2 again to make the mixing motor 24 drive the stirring shaft 25 and the stirring blade 26 to rotate to mix the ash.
