Description

Technical Field

[0001] The utility model belongs to the technical field of powder coating production, in particular to a combined high-speed mixing device. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigments, fillers and additives. It is different from ordinary solvent-based coatings and water-based coatings. Its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. In the production process of powder coating, a mixing device is required to mix and stir the raw materials.

[0003] The Chinese utility model patent currently announced as CN213078369U discloses an efficient mixing device for powder coating production and processing, including a mixing box, a motor is fixedly installed on the top of the mixing box, and three mixing shafts are fixedly installed on the outer surface of the motor output shaft. Powder coating and additives are added to the inside of the feed nozzle. When the powder coating is added, the powder coating slowly slides to the inner diameter of the mixing box through the guide plate to avoid the powder coating directly impacting the inside of the mixing box and avoiding the raising of a large amount of dust. Some of the dust will continue to float out through the feed nozzle. At this time, the dust overflowing around the feed nozzle is sucked into the inside of the suction pipe through the operation of the blower. At this time, the dust reaches the inside of the collection box through the suction pipe, the ring pipe and the air duct, and falls to the top of the slide plate, achieving the purpose of high practicality.

[0004] This patent only uses a simple mixing shaft to mix and stir the raw materials, and the mixing effect is poor. It takes a long time to complete the mixing process, which reduces the efficiency of raw material mixing. Utility Model Content

[0008] The above technical solution is adopted, by setting a shell, a mixing and stirring mechanism, a dust-proof mechanism and a discharge pipe. When in use, the raw materials are first added into the shell, and then the raw materials are efficiently mixed through the mixing and stirring mechanism.

Since the third gear is connected with the second gear through the through rod, the third gear can rotate. Since the fourth gear is meshed and connected with the third gear, the fourth gear can rotate, and then the rotating block and the stirring plate can be driven to rotate, that is, the stirring plate can revolve around the connecting rod and the fourth gear, which can make the stirring plate have a better stirring effect on the raw materials and achieve the effect of efficient mixing of the raw materials.

[0014] By adopting the above technical solution, by setting up an installation groove and a sealing gasket, when in use, the installation groove can install and fix the sealing gasket.

[0021] Furthermore: the lower surface of the shell is fixedly connected with support columns, the number of the support columns is four and they are arranged in a circle, and the lower ends of the support columns are provided with anti-slip pads.

[0022] By adopting the above technical solution, by setting the support column and the anti-skid pad, when in use, the support column can increase the ground clearance of the shell, and then the anti-skid pad can increase the friction between the support column and the ground, which can further improve the stability of the shell.

[0023] In summary, the present invention has the following beneficial effects:

[0024] By setting up a mixing and stirring mechanism, when in use, first turn on the motor so that the output shaft of the motor drives the connecting plate to rotate, and the rotating plate is connected to the connecting plate through the connecting rod, so that the connecting plate, connecting rod, rotating plate, mounting plate and stirring plate can rotate synchronously, so that the stirring plate can stir and mix the raw materials inside the shell. Then the first gear is set on the connecting rod, which can make the first gear rotate. Since the second gear is meshed with the first gear, the second gear can be rotated. Since the third gear is connected to the second gear through the through rod, the third gear can be rotated. Since the fourth gear is meshed with the third gear, the fourth gear can be rotated, and thus the rotating block and the stirring plate can be driven to rotate, that is, the stirring plate can revolve around the connecting rod and around the fourth gear, which can make the stirring plate have a better stirring effect on the raw materials and achieve the effect of efficient mixing of the raw materials.

[0025] By setting up a dust-proof mechanism, after the raw materials are added into the shell, the dust cover is fixed on the shell, and then the vacuum cleaner is turned on. The dust generated by the mixing of the raw materials is discharged into the vacuum cleaner through the connecting pipe, so as to prevent the dust generated by the mixing of the raw materials from diffusing into the air. By setting the dust cover and the shell separately in combination, the shell and the dust cover can be easily cleaned.

[0026] Based on the above improvements, the overall technical effect achieved by this device is to enable the stirring plate to revolve along two different center lines in the shell, which can improve the stirring efficiency of the stirring plate on the raw materials and thus achieve efficient mixing of the raw materials.
