DETAILED DESCRIPTION

[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 in 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-Figure 4 As shown, the utility model provides the following technical solutions:

[0022] A precision automatic quantitative weighing machine, characterized in that: it comprises a weighing piece for weighing, and a feeding piece for conveying materials along a preset path is arranged above the weighing piece;

[0023] The feeding part includes a material guide box 3, a second discharge pipe 11 and a first discharge pipe 10 are fixedly connected to the bottom of the material guide box 3, and a material guide cavity 4 is formed on the top of the material guide box 3, a second feeder 12 and a first feeder 13 are respectively installed on the second discharge pipe 11 and the first discharge pipe 10, and a material receiving funnel 14 is fixedly connected below the second feeder 12 and the first feeder 13.

[0024] Through the above technical solution, when personnel need to perform weighing work, they add the materials to be weighed into the material guide box 3. After the products are added, the container is placed on the weighing piece, the required product weight is set, the weighing piece is started, and the materials are guided by the material guide cavity 4 on the material guide box 3, so that the materials enter the second discharge pipe 11 and the first discharge pipe 10 respectively, and the materials are guided by the second discharge pipe 11 and the first discharge pipe 10, so that the materials are transported to the second feeder 12 and the first feeder 13, and the second feeder 12 and the first feeder 13 are connected. The second feeder 12 and the first feeder 13 work at the same time, and the product enters the receiving funnel 14, and the material is guided by the receiving funnel 14 to fall into the container. The weight of the material is recorded and judged by the weighing piece, so as to judge the opening and closing of the second feeder 12 and the first feeder 13. When the weight value received by the weighing piece is 98% of the set value, the second feeder 12 is automatically powered off, and the first feeder 13 continues to run. At this time, the first feeder 13 only works in micro-motion. When the weight reaches 100%, the first feeder 13 stops working, and one cycle is completed when it stops.

[0025] Specifically, in one embodiment, regarding the above-mentioned weighing device:

[0026] like Figure 1-Figure 3 As shown, the weighing piece includes a weighing platform 1 , one side of the weighing platform 1 is fixedly connected to a support frame 2 , and a free end of the support frame 2 is fixedly connected to one side of a material guide box 3 .

[0027] In this embodiment, after the container is placed on the weighing platform 1, the weighing platform 1 is subjected to a taring operation, and after the material falls into the container, the material can be weighed.

[0028] In order to facilitate the automatic operation of the second feeder 12 and the first feeder 13, as Figure 1-Figure 2 As shown, two optical fiber sensors 5 are symmetrically installed on the top of the material guide box 3. When material is added into the material guide box 3 and the optical fiber sensor 5 senses the presence of material, the second feeder 12 and the first feeder 13 work simultaneously.

[0029] When the material guide cavity 4 is conveying materials, in order to improve the material conveying efficiency, as Figure 1-Figure 2 As shown, the interior of the material guiding cavity 4 is inclined downward from the inner wall to the middle position to form a material guiding slope 15.

[0030] When the loading hopper 6 conveys materials, in order to improve the conveying efficiency, as Figure 1-Figure 3As shown, a loading funnel 6 is fixedly connected to the top of the material guide box 3, and the top of the loading funnel 6 is opened to form a material storage cavity 9;

[0031] The interior of the storage chamber 9 is rotatably connected with an auger 8 .

[0032] In this embodiment, when personnel need to add materials, the materials are added to the storage chamber 9 at the top of the loading funnel 6. When personnel need to weigh the materials, the auger 8 is rotated to drive the materials to move inside the loading funnel 6 until the materials are discharged through the loading funnel 6 and fall into the material guide chamber 4 inside the material guide box 3.

[0033] How to rotate the auger 8? Figure 1-Figure 3 As shown, a motor 7 is fixedly connected to the top of the charging hopper 6 , and an output end of the motor 7 is connected to an auger 8 .

[0034] In this embodiment, when the auger 8 needs to be driven to rotate, the motor 7 is operated, and then the motor 7 drives the auger 8 to rotate, thereby conveying the material.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
