[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] The embodiment of the utility model discloses a precision weighing feeder.

[0025] The utility model provides Figure 1-4The precision weighing feeder shown in the figure includes a box body 1, a hopper 2 is fixedly connected to the side wall of the box body 1, a feeding auger device 3 is fixedly connected to the side wall cavity of the box body 1, the side wall of the hopper 2 corresponds to the bottom feed port position of the feeding auger device 3 through an opening, a storage bin 4 is fixedly connected to the top of the cavity of the box body 1, the side wall of the storage bin 4 corresponds to the top discharge port position of the feeding auger device 3 through an opening, an electric valve 5 is fixedly connected to the bottom of the storage bin 4, a counterweight bin 6 is fixedly connected to the bottom of the electric valve 5, a support plate 7 is rotatably connected between the side walls of the cavity of the counterweight bin 6, a first electric push rod 8 is rotatably connected to the bottom of the cavity of the box body 1, the other end of the first electric push rod 8 is rotatably connected to the other end of the bottom of the support plate 7, a weighing sensor 9 is fixedly connected to the top of the weighing sensor 9, a weighing bucket 10 is fixedly connected, and the side wall of the support plate 7 is slidably connected to a stopper through a limit mechanism. The plate 11 and the side wall of the box body 1 are fixedly connected with a control module 12, and the bottom of the counterweight bin 6 is fixedly connected with a feeding pipe 13. By using the set upper hopper 2, the material is poured into the upper hopper 2 and falls into the feeding auger device 3, and is transported to the cavity of the storage bin 4 through the feeding auger device 3. The control module 12 controls the electric valve 5 to discharge the material, and the material falls into the weighing bucket 10 and is weighed by the weighing sensor 9. When the required weight is reached, the control module 12 controls the electric valve 5 to close, and the first electric push rod 8 is retracted to pull the support plate 7 to rotate downward, so that the weighing bucket 10 is tilted, and the material is discharged by opening the limit mechanism. The fallen material is discharged from the feeding pipe 13 through the opening at the bottom of the counterweight bin 6, and is fed and filled through the feeding pipe 13, thereby solving the problem that the existing weighing feeder easily causes powdered materials to splash, and cannot accurately feed the material, and is prone to overfeeding or insufficient feeding and fails to achieve the expected effect.

[0026] In order to limit the material in the weighing bucket 10 during weighing, Figure 1-4 As shown, the limiting mechanism includes a second electric push rod 14, a connecting block 15 and a first slide 16. The side wall of the support plate 7 is fixedly connected to the second electric push rod 14, and one end of the second electric push rod 14 is fixedly connected to the connecting block 15. The side wall of one end of the weighing bucket 10 is slidably connected to the two ends of the baffle 11 by opening a first slide 16. The side wall of the connecting block 15 is fixedly connected to the side wall of the baffle 11. The baffle 11 set in the first slide 16 is used to limit the material in the weighing bucket 10 during weighing. During discharge, the second electric push rod 14 is retracted downward to drive the baffle 11 to slide downward in the first slide 16, so that the material loses the limit and automatically slides out.

[0027] In order to facilitate the feeding of the container, Figure 1As shown, a placement port 17 is opened at one end of the side wall of the box body 1, and a third electric push rod 18 is fixedly connected to the bottom cavity. One end of the third electric push rod 18 passes through the side wall of the box body 1 and is fixedly connected to a placement plate 19. The placement plate 19 corresponds to the position of the filling pipe 13. The third electric push rod 18 is used to push the placement plate 19 up and down, so that containers of different sizes on the top of the placement plate 19 are close to the filling pipe 13, and the material is prevented from splashing out by cooperating with the filling pipe 13.

[0029] In order to avoid the accumulation of dust when the filling pipe 13 is not used, Figure 1 and 2 As shown, the side walls at both ends of the box body 1 are slidably connected with dust shields 22 through the second sliding openings 21. The dust shields 22 arranged at the second sliding openings 21 at both ends are slid and closed to protect the filling pipe 13 when not in use, thereby avoiding dust accumulation in the filling pipe 13 when not in use.

[0030] Finally, in order to facilitate moving to other work areas, such as Figure 1 As shown, a plurality of universal wheels 23 are fixedly connected to the bottom of the box body 1, and the plurality of universal wheels 23 are provided to facilitate movement to other working areas.

[0031] Working principle:

[0032] When in use, the material is poured into the upper hopper 2 and dropped into the feeding auger device 3. The container for storing the material is placed on the top of the placement plate 19 in the placement port 17. The placement plate 19 is pushed up and down by the third electric push rod 18, so that the containers of different sizes on the top of the placement plate 19 are close to the feeding pipe 13. The material is prevented from splashing out by cooperating with the feeding pipe 13. The material is transported to the storage bin 4 cavity through the feeding auger device 3, and the electric valve 5 is controlled by the control module 12 to discharge the material. The material falls into the weighing bucket 10 and is weighed by the weighing sensor 9 to reach the required weight. When measuring, the control module 12 controls the electric valve 5 to close, and the first electric push rod 8 is retracted to pull the support plate 7 to rotate downward, so that the weighing bucket 10 is tilted, and the second electric push rod 14 is retracted downward to drive the baffle 11 to slide downward in the first slide 16, so that the material loses the limit and automatically slides out, and the fallen material is discharged from the feeding pipe 13 through the opening at the bottom of the counterweight bin 6, and the material is fed and filled through the feeding pipe 13, thereby solving the problem that the existing weighing feeder easily causes powdered materials to splash, and cannot accurately feed the materials, and is prone to overfeeding or insufficient feeding and fails to achieve the expected effect.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
