Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying, in particular to a paint machine with paint premixing function. Background Art

[0002] Paint spraying machine is also called spray gun. It is a machine that atomizes and sprays decorative paint onto the surface of a building. It can be divided into air spray and airless spray according to the working principle.

[0003] An air sprayer is a machine that uses compressed air to atomize the paint and spray it. There are two types of feeding methods: suction type and self-falling type. ① The suction type material tank is located below the spray gun, and compressed air is introduced from the tail of the gun. After the trigger is opened, the negative pressure generated by the high-speed airflow sucks the paint out of the material tank and sprays it out in a mist along with the airflow. It is suitable for spraying paint and other coatings, so it is also called a paint spray gun. ② The self-falling type material tank is located above the spray gun. The paint falls to the muzzle by its own weight and is sprayed out along with the compressed air (also called a bucket spray gun). It is suitable for spraying coatings containing solid particles;

[0004] Among them, the traditional suction type organic spraying method is accompanied by the reduction of paint in the material tank, and the paint liquid level in the material tank continues to drop. The difficulty of sucking the paint out of the material tank through the negative pressure generated by the high-speed airflow will gradually increase, so there will be difficulties in spraying. In addition, the traditional suction type organic spraying method does not pre-mix the paint, and the paint has the problem of uneven mixing, especially after long-term non-use and precipitation. The above two situations are not conducive to the normal spraying of the paint. Utility Model Content

[0010] Preferably, an air pump is installed at one end of the airflow channel and a nozzle is installed at the other end, and the output end of the air pump is connected to the input end of the nozzle through the airflow channel.

[0011] Preferably, a plurality of columns are installed between the lower bottom of the top seat and the upper top of the base, a push handle is fixedly installed at one end of the base, and universal wheels are installed at the four corners of the bottom end of the base.

[0012] The beneficial effects of the utility model are:

[0013] First, a paint pump is arranged in the air flow channel. The paint pump extracts the paint at the bottom of the inner cavity of the material tank through the extraction pipe and sprays it into the inner cavity of the air flow channel. After the air pump pressurizes the air flow channel, the liquid paint will be squeezed into a mist and finally sprayed out from the nozzle along with the air flow. The lowering of the paint level in the material tank will not cause difficulty in extracting the paint, resulting in inconvenience in paint spraying.

[0014] Then, a rotatable rotating tube is arranged in the material tank, and a plurality of stirring paddles are installed on the outer tube wall of the rotating tube. The rotating tube is driven to rotate by a motor and then the plurality of stirring paddles are driven to rotate, so that the paint in the material tank is pre-mixed in advance. After long-term non-use and precipitation, the paint can be ensured to be evenly mixed by stirring. What is more special is that the drawing tube is arranged in the inner tube wall of the rotating tube, and a plurality of through holes are formed in the outer tube wall of the rotating tube through the inner cavity. This enables the drawing tube to still draw the paint in the tank cavity of the material tank through the through holes during the rotation of the rotating tube, and has the characteristics of reasonable design and convenient use.

[0029] Working principle:

[0030] In the first step, the paint is continuously poured from the hopper 53. The paint impacts the roller strip 52 on the outer roller wall of the rotating roller 51 due to gravity, thereby driving the rotating roller 51 to rotate, so that the paint feeding is more uniform and stable. Finally, the paint enters the material tank 2 and the valve 55 is closed.

[0031] In the second step, the motor 4 is started again to drive the rotating tube 41 to rotate, and then drive the plurality of stirring paddles 43 to rotate, so as to pre-mix the coating in the material tank 2 in advance. After long-term non-use and precipitation, the coating can be evenly mixed by stirring. More particularly, the extraction pipe 32 is arranged in the inner tube wall of the rotating tube 41, and the outer tube wall of the rotating tube 41 penetrates the inner cavity to form a plurality of through holes 42, so that the extraction pipe 32 can still extract the coating in the tank cavity of the material tank 2 through the through holes 42 during the rotation of the rotating tube 41, and has the characteristics of reasonable design and convenient use.

After the air pump 33 pressurizes the air flow channel 3, the liquid paint will be squeezed into a mist, and finally sprayed out from the nozzle 34 accompanied by the air flow, so that the paint extraction will not be difficult due to the reduction of the paint liquid level in the material tank 2, and it will not cause inconvenience in paint spraying;

[0033] The fourth step is to push the entire coating machine to move by rolling the push handle 13 and the four universal wheels 14, so as to facilitate the mobile spraying of coatings over a large area.
