[0002] Food dispensing machines are widely used mechanical equipment in the food industry. They automate the material dispensing process, eliminating the need for manual weighing or distributing of materials, significantly reducing manual operation time and workload. They can continuously dispense materials according to preset parameters, significantly improving production continuity and efficiency, making them particularly suitable for large-scale food production enterprises. Furthermore, thanks to their precise metering and dispensing system, food dispensing machines can accurately dispense large quantities of materials in a short time.

[0003] Weight-based food dispensing machines are a type of food dispensing machine that uses high-precision weight sensors to measure the weight of food. During operation, food enters the dispensing container, and when the preset weight value is reached, the sensor sends a signal to stop feeding. It boasts high dispensing accuracy and is suitable for many types of food.

[0004] However, for materials that are prone to clumping or have uneven particle size, accumulation or uneven distribution often occurs when they enter the discharge mechanism of existing weight-based food packaging machines, affecting the accuracy of subsequent dispensing. Therefore, there is an urgent need to develop an automatic weighing and dispensing machine to solve the above problems. Utility Model Content

[0040] Referring to Figures 1 to 7The embodiment discloses an automatic weighing and separating machine which is used for separating materials with specific weight. The automatic weighing and separating machine comprises a material receiving part 7, a shell assembly 1, a separating structure arranged in the inner cavity of the shell assembly 1, a control mechanism 8, a discharging mechanism 2 electrically connected with the control mechanism 8, a weighing mechanism 3 and a separating mechanism 4. The control mechanism 8 is fixed in the shell assembly 1. The discharging mechanism 2 comprises a discharging groove 21 and a spiral vibration assembly connected with the discharging groove 21. The control mechanism 8 can control the rotation frequency of the spiral vibration assembly of the discharging mechanism 2. The discharging groove 21 is provided with a first outlet 211. The weighing mechanism 3 comprises a weighing machine 31 and a weighing container 32 connected with the weighing machine 31 and used for weighing the materials. The first outlet 211 of the discharging groove 21 is arranged above the inlet 322 of the weighing container 32, so that the materials falling from the discharging groove 21 can enter the weighing container 32 from the inlet 322. The blocking plate 42 of the separating mechanism 4 is movably arranged at the second outlet 321 of the weighing container 32, so that the second outlet 321 of the weighing container 32 can be blocked or opened.

[0041] Specifically, the spiral vibration assembly comprises a speed reducer 221, a spiral blade 222 and a vibration spring 223. The center of the spiral blade 222 is sleeved on a rotating shaft 2221. The speed reducer 221 is arranged outside the discharging groove 21. The rotating output shaft 2211 of the speed reducer 221 penetrates through the hole in the side of the discharging groove 21 and is inserted into the inner cavity of the discharging groove 21. The rotating output shaft 2211 is fixedly connected with the rotating shaft 2221. The vibration spring 223 is arranged on the blade 2222 of the spiral blade 222. One end of the vibration spring 223 is fixedly connected with the rotating output shaft 2211.

[0042] In the embodiment, when the speed reducer 221 is started, the rotating shaft 2221 connected with the speed reducer 221 is rotated. Since the center of the spiral blade 222 is sleeved on the rotating shaft 2221, the rotation of the rotating shaft 2221 drives the spiral blade 222 to rotate. During the rotation of the spiral blade 222, the spiral blade 222 pushes the materials to move along the spiral direction of the spiral blade 222. At the same time, the vibration spring 223 arranged on the blade 2222 of the spiral blade 222 vibrates with the rotation of the spiral blade 222. The vibration is transmitted to the spiral blade 222 and the materials in contact with the spiral blade 222, so that the materials are vibrated while being pushed to move by the spiral blade 222.

[0043] In this embodiment, the vibration generated by the vibration spring 223 can effectively prevent the material from being blocked on the spiral blade 222 or during the conveying process. For materials that are prone to caking or have uneven particles, vibration can keep them in a loose state, ensuring that the material can move smoothly along the spiral blade 222, thereby ensuring the continuity and stability of the material conveying. Vibration can make the material more evenly distributed on the spiral blade 222 before entering the material distribution area, avoiding the accumulation or uneven distribution of the material. In this way, during the material distribution, the material can be distributed more accurately according to the preset distribution amount, improving the accuracy and consistency of the material distribution.
