[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a hopper structure of an anti-blocking powder coating production equipment, including a bracket 1, a hopper 2 is fixedly installed on the bracket 1 through a support rod, a motor 3 is fixedly installed on one side of the bracket 1, a rotating rod 4 is rotatably arranged at the bottom of the hopper 2 at the discharge position, and evenly distributed scattering rollers 5 are fixedly installed on the rotating rod 4, the output shaft end of the motor 3 is fixedly installed with one end of the scattering roller 5, a slideway 6 is opened on the scattering roller 5, a spring 7 is arranged in the slideway 6, a weight block 8 is slidably arranged in the slideway 6, and both ends of the spring 7 are fixedly installed with the scattering roller 5 and the weight block 8 respectively, a movable rod 9 is slidably arranged on the slideway 6 and fixedly installed with the weight block 8, and a rubber block 10 is fixedly installed on one end of the movable rod 9 close to the inner wall of the hopper 2.

[0022] First, after the paint production equipment conveys the powder paint into the hopper 2, the motor 3 starts to work, and the output shaft of the motor 3 is fixedly connected to one end of the scattering roller 5. Therefore, the rotation of the motor 3 will drive the rotating rod 4 and the scattering roller 5 to rotate at the discharge point in the hopper 2, which can effectively scatter and stir the powder paint to prevent it from agglomerating or clogging. A slide 6 is provided on the scattering roller 5, and a spring 7, a weight block 8 and a movable rod 9 are installed in the slide 6 to increase the rotation power of the output shaft of the motor 3. When the scattering roller 5 rotates, the weight block 8 and the movable rod 9 are acted upon by centrifugal force to pull the spring 7 in the slide 6 to slide toward the side wall of the hopper 2, so that the rubber block 10 fits tightly against the inner wall of the hopper 2 to further prevent the occurrence of blockage. The anti-blocking design of the hopper 2 structure of the powder coating production equipment can effectively avoid the occurrence of blockage when the hopper 2 conveys powder coating, significantly improves the fluency and efficiency of the production process, reduces production interruptions caused by blockage, thereby ensuring the stability of coating production and having strong practicality.

[0023] The diameter of the movable rod 9 is adapted to the diameter of the slide 6. The end of the scattering roller 5 is located on the slide 6 and is provided with a sealing rubber ring, which fits the surface of the movable rod 9. The sealing rubber ring can prevent the powder coating from entering the slide 6 and affecting the sliding of the movable rod 9.

[0024] The two sides of the hopper 2 are set as inclined surfaces, and the side of the rubber block 10 close to the inclined surface of the inner wall of the hopper 2 is set as an arc edge; since the two sides of the hopper 2 are designed as inclined surfaces, the side of the rubber block 10 close to the inclined surface of the inner wall of the hopper 2 is set as an arc edge, which enables the rubber block 10 to better fit the inclined surface to scrape and break up the paint. When the breaking roller 5 rotates, the rubber block 10 moves up and down along the inclined surface to effectively scrape off the paint attached to the inner wall of the hopper 2.

[0025] A feeding pipe 11 is fixedly installed on the bracket 1, and a feeding port 12 and a feeding port 13 are provided on the feeding pipe 11. The feeding port 12 is connected to the discharge point at the bottom of the hopper 2. A cross bar 14 is rotatably installed in the feeding pipe 11, and a spiral blade 15 is fixedly installed on the cross bar 14. A driving member 16 is provided on the bracket 1, and the driving member 16 includes a driving wheel 161 fixedly installed on the output shaft of the motor 3, a driven wheel 162 rotatably arranged on the bracket 1, and a belt 163 sleeved on the driving wheel 161 and the driven wheel 162. One end of the cross bar 14 is fixedly installed on the middle part of the driven wheel 162; The feed pipe 11 fixedly installed on the frame 1 is connected to the discharge point at the bottom of the hopper 2. When the paint flows out from the bottom of the hopper 2, it enters the feed pipe 11. A spiral blade 15 is fixed on the cross bar 14 rotatably arranged in the feed pipe 11. The spiral blade 15 rotates under the drive of the driving member 16 to push the paint forward along the feed pipe 11. The driving member 16 is composed of a driving wheel 161 on the output shaft of the motor 3, a driven wheel 162 on the bracket 1, and a belt 163 arranged therebetween. One end of the cross bar 14 is fixedly installed on the middle part of the driven wheel 162, so the rotation of the motor 3 can simultaneously drive the scattering roller 5 and the spiral blade 15 to rotate.

[0026] A collecting box 17 is slidably arranged on the bracket 1, and the box opening of the collecting box 17 is opposite to the discharge port 13; the collecting box 17 slidably arranged on the bracket 1 is used to collect the paint flowing out of the discharge port 13 of the feeding pipe 11. When the collecting box 17 is full, it can be conveniently slid out to collect and process the paint.

[0027] Working principle:

[0028] First, after the paint production equipment conveys the powder paint into the hopper 2, the motor 3 starts to work, and the output shaft of the motor 3 is fixedly connected to one end of the scattering roller 5, so the rotation of the motor 3 drives the rotating rod 4 and the scattering roller 5 to rotate at the discharge point in the hopper 2, which can effectively scatter and stir the powder paint to prevent it from agglomerating or clogging;

[0029] A slideway 6 is provided on the scattering roller 5, and a spring 7, a weight block 8 and a movable rod 9 are installed in the slideway 6, which can increase the rotation power of the output shaft of the motor 3. When the scattering roller 5 rotates, the weight block 8 and the movable rod 9 are acted upon by the centrifugal force to pull the spring 7 in the slideway 6 to slide toward the side wall of the hopper 2, so that the rubber block 10 is closely fitted to the inner wall of the hopper 2 and moves. Since the two sides of the hopper 2 are designed as inclined surfaces, the side of the rubber block 10 close to the inclined surface of the inner wall of the hopper 2 is set as an arc edge, which enables the rubber block 10 to better fit the inclined surface to scrape and scatter the paint. When the scattering roller 5 rotates, the rubber block 10 moves up and down along the inclined surface, effectively scraping off the paint attached to the inner wall of the hopper 2, and further preventing the occurrence of blockage;

[0030] At the same time, the feed pipe 11 fixedly installed on the bracket 1 is connected to the discharge point at the bottom of the hopper 2. When the paint flows out from the bottom of the hopper 2, it enters the feed pipe 11. A spiral blade 15 is fixed on the cross bar 14 rotatably arranged in the feed pipe 11. The spiral blade 15 rotates under the drive of the driving member 16 to push the paint forward along the feed pipe 11. The driving member 16 is composed of a driving wheel 161 on the output shaft of the motor 3, a driven wheel 162 on the bracket 1, and a belt 163 sleeved therebetween. One end of the cross bar 14 is fixedly installed with the middle part of the driven wheel 162, so the rotation of the motor 3 can simultaneously drive the scattering roller 5 and the spiral blade 15 to rotate;

[0031] Finally, the collecting box 17 slidably arranged on the bracket 1 is used to collect the paint flowing out from the discharge port 13 of the conveying pipe 11. When the collecting box 17 is full, it can be conveniently slid out to collect and process the paint.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
