DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] A weighing device for powder coatings, comprising a storage barrel 2, wherein the upper side of the storage barrel 2 is fixedly connected to a motor 1, the output shaft of the motor 1 is fixedly connected to a circular tube 19, the upper side of the circular tube 19 is fixedly connected to an air outlet 18, a spiral blade 20 is fixedly arranged around the outer side of the lower part of the circular tube 19, the lower part of the storage barrel 2 is fixedly connected to a discharge pipe 3, the lower part of the spiral blade 20 is located in the discharge pipe 3, the side of the discharge pipe 3 is fixedly connected to a symmetrical rectangular tube 4, two slide plates 16 are respectively provided in the two rectangular tubes 4, a semicircular groove 17 is respectively provided in the middle of one side of the slide plate 16, the outer sides of the slide plates 16 are respectively fixedly connected to the telescopic shaft of a cylinder 5, and the cylinder body of the cylinder 5 is fixedly connected to the rectangular tube 4.

[0025] The lower part of the discharge pipe 3 is arranged in the sleeve 7, and the sleeve 7 is fixedly connected to the connecting rod 15, and the connecting rod 15 is fixedly connected to the sleeve 9. The lower part of the circular tube 19 is sleeved in the sleeve 9. The upper side of the sleeve 7 is fixedly connected to the telescopic shaft of the cylinder 2 6, and the cylinder body of the cylinder 2 6 is fixedly connected to the lower side of the rectangular tube 4.

[0026] An annular plate 8 is fixedly connected to the lower portion of the sleeve 7 .

[0027] A group of columns 10 are fixedly connected to the lower side of the storage barrel 2 , and the lower ends of the columns 10 are fixedly connected to the bottom plate 11 .

[0028] A weighing scale 12 is disposed on the upper side of the bottom plate 11 .

[0030] Working principle: put powder coating into the storage barrel 2 through the upper opening of the storage barrel 2, and thread the barrel cover 13 to the upper opening of the storage barrel 2. When it is necessary to pack and weigh, first put the storage barrel 14 on the weighing scale 12, start the cylinder 2 6, and the cylinder 2 6 drives the sleeve 7, the annular plate 8 and the sleeve 9 to move downward, the sleeve 7 moves along the discharge pipe 3, and the sleeve 9 moves along the circular tube 19, so that the annular plate 8 covers the upper opening of the storage barrel 14, so that the storage barrel 14 and the annular plate 8 form a closed space, close the cylinder 2 6, and then start the two cylinders 1 5, the slide plate 16 moves away from the circular tube 19, so that the discharge pipe 3 is in an open state, and then start the motor 1, the motor 1 drives the circular tube 19 and the spiral blade 20 to rotate, so that the powder coating continuously falls into the storage barrel 14. 4 and the annular plate 8 form a closed space. After the powder coating enters the material storage barrel 14, the powder coating occupies the space of the material storage barrel 14, and the air in the material storage barrel 14 will be squeezed out of the material storage barrel 14, and the air in the material storage barrel 14 is discharged through the sleeve 9, the circular tube 19, the air outlet 18 and the filter cotton 21.
