Specific Embodiment

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:

[0017] As Figure 1-2As shown in the figure, an automatic weighing device for powder coatings includes a base 1. Above the base 1, there is a hopper 2. Below the hopper 2, there is a cylinder 3. The cylinder 3 is placed on a platform scale 4. Below the platform scale 4, there is a lifting mechanism 5 for driving the platform scale 4 to rise and fall. On both sides of the hopper 2, there are positioning mechanisms 6 for positioning the cylinder 3. In the present utility model, the lifting mechanism 5 is used to drive the platform scale 4 to rise and fall, and the platform scale 4 further drives the cylinder 3 to rise and fall. When discharging materials, the cylinder 3 is controlled to rise, and the platform scale 4 weighs the materials in the cylinder 3. When not discharging materials, the cylinder 3 is controlled to fall. The precise positioning of the cylinder 3 is achieved through the positioning mechanism 6, so that the cylinder 3 can just be directly below the hopper 2, ensuring the accuracy of the weighing result.

[0018] Specifically, the positioning mechanism 6 includes a fixing plate 61, a positioning plate 62 and an arc plate 63. The fixing plate 61 is arranged on both sides of the cylinder 3. The positioning plate 62 is arranged at the lower part of the fixing plate 61. The positioning plate 62 is inclined outward from top to bottom. The fixing plate 61 is connected to the cylinder 3 through the arc plate 63. The functions of the positioning plate 62 are as follows: First, when the cylinder 3 rises, it plays a certain guiding role in the movement of the cylinder 3, so that the cylinder 3 will not deviate from the outlet of the hopper 2. Second, since the two positioning plates 62 are respectively inclined outward, when used in cooperation with the hopper 2, they cover the cylinder 3, thereby reducing the impurities entering the cylinder 3.

[0019] During the rising process of the cylinder 3, it is easy to touch the fixing plate 61, and at this time, inaccurate weighing will occur. To reduce the occurrence of this phenomenon, vibration motors 7 are respectively installed on the fixing plates 61 on both sides of the cylinder 3 in the present utility model. When the vibration motors 7 are turned on, the vibration of the vibration motors 7 can separate the fixing plate 61 from the cylinder 3. At the same time, the vibration motors 7 also have the function of accelerating the discharging of materials.

[0020] Furthermore, the lifting mechanism 5 includes a pneumatic cylinder 51 and a support plate 52. The pneumatic cylinder 51 is fixed on a bracket. The piston rod of the pneumatic cylinder 51 is fixed to the support plate 52. The platform scale 4 is arranged on this support plate 52.

[0021] Furthermore, at least two guiding components 8 are arranged between the base 1 and the support plate 52. Specifically, the guiding component 8 includes a guiding rod 81 and a guiding sleeve 82. The lower end of the guiding sleeve 82 is fixed to the base 1. The upper end of the guiding sleeve 82 is sleeved with the guiding rod 81. The upper end of the guiding rod 81 is fixed to the support plate 52. The design of the guiding component 8 enables the support plate 52 to rise and fall stably, thus ensuring the accuracy of weighing.

[0022] Further, an installation hole 53 is provided on the support plate 52, and the fixing column 41 at the bottom of the platform scale 4 is arranged in the installation hole 53, realizing the fixation of the platform scale 4.

[0023] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above-described embodiments and descriptions in the specification are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and all these changes and improvements fall within the scope of the present invention claimed.
