DETAILED DESCRIPTION

[0029] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 As shown, a coating machine with coating premixing comprises a base 1, a sloping plate 11 is fixedly mounted on the top of the base 1, a mixing chamber 2 is slidably mounted on the top of the sloping plate 11, a feed pipe 201 is fixedly mounted on the top of the mixing chamber 2; a stirring mechanism is also included for premixing the coating; the stirring mechanism comprises two first pulleys 23, one of the first pulleys 23 is fixedly connected to the top of a second motor 232, the second motor 232 is fixedly mounted on the top of the mixing chamber 2, and the two first pulleys 23 are both rotatably mounted on the mixing chamber 2, the two first pulleys 23 are driven by the first belt 231, the bottoms of the two first pulleys 23 are fixedly connected with the connecting shaft 24, the outer surface of the connecting shaft 24 is fixedly installed with a stirring plate 241, one side of the stirring plate 241 is provided with a material passing hole 2411, the bottom of the first pulley 23 is fixedly installed with a guide plate 242, the inner wall of the mixing chamber 2 is slidably installed with a second scraper 34 and two first scrapers 325, the inner cavity of the mixing chamber 2 is fixedly installed with a feeding pipe 41, and one end of the feeding pipe 41 is fixedly connected with a nozzle 44.

[0031] Before the coating machine works, multiple coatings need to be pre-mixed. When the existing coating machine encounters a highly viscous coating during pre-mixing, it is easy to cause uneven mixing of the coatings. In addition, the through hole may cause uneven distribution of the coating due to centrifugal force during rotation, affecting the continuous suction efficiency of the extraction pipe.

[0032] When the present invention is in use, first, the paint is poured into the inner cavity of the mixing chamber 2 through the feeding pipe 201, and then the paint begins to be mixed. The output shaft of the second motor 232 drives the first pulley 23 to rotate. After the first belt 231 is driven, the two first pulleys 23 start to rotate, and the two first pulleys 23 respectively drive the two connecting shafts 24 to rotate. The two connecting shafts 24 drive the stirring plate 241 and the guide plate 242 to rotate. The guide plate 242 can stir the paint located at the bottom of the inner cavity of the base 1 to the upper part of the inner cavity of the base 1, and then the paint is stirred by the stirring plate 241. When the stirring plate 241 rotates, the paint will pass through the material hole 2411, which can make the stirring plate 241 rotate smoothly, and the stirring plate 241 will not be difficult to rotate due to excessive resistance of the paint. At the same time, the paint on the bottom wall of the base 1 can be cleaned by the first scraper 325 and the second scraper 34, which is conducive to stirring the paint through the guide plate 242 and the stirring plate 241 and stirring the paint more evenly.

[0033] Further, such as Figure 2 and Figure 3 As shown, four support rods 12 are fixedly installed on the top of the base 1, and the outer surfaces of two adjacent support rods 12 are fixedly connected with reinforcing plates 13. Four rollers 21 are rotatably installed on the bottom of the mixing chamber 2. Four slide grooves 111 are opened on the top of the inclined plate 11, and the four rollers 21 are rotatably installed on the inner surfaces of the four slide grooves 111 respectively.

[0034] A first motor 22 is fixedly installed at the bottom of the reinforcing plate 13, and a disc 221 is fixedly connected to the output shaft of the first motor 22. A cylinder 222 is eccentrically arranged on one side of the disc 221. A connecting rod 223 is rotatably connected to the outer surface of the cylinder 222, and the connecting rod 223 is rotatably installed on one side of the mixing chamber 2.

[0035] When the present invention is in use, the entire paint premixing machine is supported by the reinforcing plate 13 and the support rod 12. When the paint in the inner cavity of the mixing chamber 2 is stirred, the disc 221 is rotated by the output shaft of the first motor 22, and the disc 221 drives the cylinder 222 to perform eccentric movement. At the same time, the cylinder 222 drives the mixing chamber 2 to slide along the inclined plate 11 through the connecting rod 223. At this time, the roller 21 will slide on the inner surface of the slide groove 111. This can make the sliding of the mixing chamber 2 smoother and can also speed up the mixing of the paint in the inner cavity of the mixing chamber 2 by shaking the mixing chamber 2.

[0036] Further, such as Figure 5 As shown, two second pulleys 321 are rotatably installed on one side of the mixing chamber 2, and the two second pulleys 321 are driven by the second belt 32, one side of the second pulley 321 is fixedly connected to the third motor 3, and the third motor 3 is fixedly installed on one side of the mixing chamber 2, and one side of the second pulley 321 is fixedly connected to a worm 322, and the outer surface of the worm 322 is meshed with a worm wheel 323;

[0037] Two first reciprocating screw rods 324 are rotatably installed in the inner cavity of the mixing chamber 2, and the two first reciprocating screw rods 324 are fixedly connected, one of the first reciprocating screw rods 324 is fixedly installed on one side of the worm gear 323, and the two first scrapers 325 are respectively threadedly installed on the outer surfaces of the two first reciprocating screw rods 324;

[0038] A second reciprocating screw 33 is fixedly connected to one side of the other second pulley 321 , the second scraper 34 is threadedly mounted on the outer surface of the second reciprocating screw 33 , and a suction pipe 4 is fixedly mounted on the inner wall of the mixing chamber 2 .

[0039] When the present invention is in use, the output shaft of the third motor 3 drives the second pulley 321 to rotate. After the second belt 32 transmits the transmission, the two second pulleys 321 start to rotate, one of the second pulleys 321 drives the second reciprocating screw 33 to rotate, and the second reciprocating screw 33 further drives the second scraper 34 to slide back and forth along the inner wall of the mixing chamber 2 to scrape up the paint on the bottom wall of the mixing chamber 2, and the other second pulley 321 drives the worm 322 to rotate, and the worm wheel 323 can be driven to rotate through the meshing action of the worm 322 and the worm wheel 323, and the worm wheel 323 drives the two first reciprocating screws 324 to rotate, and the two first reciprocating screws 324 respectively drive the two first scrapers 325 to reciprocate, and the two first scrapers 325 cooperate with the second scraper 34 to scrape up the paint at the bottom of the inner cavity of the mixing chamber 2, so as to facilitate more uniform mixing of the paint.

[0040] Further, such as Figure 5 and Figure 6 As shown, the top of the suction pipe 4 is fixedly connected to a feeding pipe 41, one end of the feeding pipe 41 is fixedly connected to a pumping machine 42, the pumping machine 42 is fixedly installed on the top of the mixing chamber 2, and one side of the pumping machine 42 is fixedly connected to a discharge pipe 411;

[0041] The outer surface of the discharge pipe 411 is fixedly connected to a support plate 43 , a limiting groove 131 is provided on the top of the reinforcing plate 13 , the support plate 43 is slidably installed on the inner surface of the limiting groove 131 , and one end of the discharge pipe 411 is fixedly connected to a nozzle 44 .

[0042] When the present invention is in use, the feeder 42 sucks the paint out of the inner cavity of the mixing chamber 2 through the feed pipe 41 and the suction pipe 4, and then the paint is sprayed out through 411 and the nozzle 44. During operation, the staff holds 411 and points the nozzle 44 to the place where spraying is required to achieve the paint spraying work. When the first motor 22 drives the mixing chamber 2 to slide along the inclined plate 11, the feeder 42 will also slide with 411. In order to increase the stability of 411, 411 will slide on the inner surface of the limit groove 131 with the support plate 43. At the same time, fixing 411 by the support plate 43 can also avoid entanglement between 411 and the paint pre-mixing coating machine.

[0043] Working principle: first, the paint is transported to the inner cavity of the mixing chamber 2 through the feed pipe 201, and then the first pulley 23 is rotated by the output shaft of the second motor 232. After the transmission by the first belt 231, the two first pulleys 23 start to rotate, and the two first pulleys 23 respectively rotate with the two connecting shafts 24. The connecting shafts 24 rotate with the stirring plate 241 and the guide plate 242. The guide plate 242 can stir the paint at the bottom of the inner cavity of the mixing chamber 2 to the upper part of the inner cavity of the mixing chamber 2. The paint can be stirred and mixed by the stirring plate 241. At the same time, the disc 221 is rotated by the output shaft of the first motor 22. The disc 221 can drive the mixing chamber 2 to slide along the inclined plate 11 through the cylinder 222 and the connecting rod 223. This can make the mixing chamber 2 shake with the paint in the inner cavity, which is conducive to accelerating the stirring of the paint in the inner cavity of the mixing chamber 2.

[0044] The output shaft of the third motor 3 drives the second pulley 321 to rotate, and after the second belt 32 is driven, the two second pulleys 321 start to rotate, and one of the second pulleys 321 drives the second reciprocating screw 33 to rotate, so that the second reciprocating screw 33 can drive the second scraper 34 to reciprocate on the inner wall of the mixing chamber 2, and the other second pulley 321 is driven by the worm 322 and the worm wheel 323, so that the worm wheel 323 drives the two first reciprocating screws 324 to rotate, and the two first reciprocating screws 324 can drive the two first scrapers 325 to reciprocate on the inner wall of the mixing chamber 2, so as to scrape up the paint on the inner wall of the mixing chamber 2, and the cooperation between the first scraper 325 and the second scraper 34 can accelerate the flow of the paint in the inner cavity of the mixing chamber 2, which is conducive to accelerating the mixing of the paint, and after the mixing is completed, the pumping machine 42 extracts the paint in the inner cavity of the mixing chamber 2 through the feeding pipe 41 and the suction pipe 4, and finally the paint is sprayed out through the support plate 43 and the nozzle 44.
