The installation position outside the weighing tube 405 has obvious advantages during maintenance and calibration operation. The technician does not need to face the complex environment inside the weighing tube 405 which may have residual material. The technician can easily check, debug, replace key components or perform re-calibration procedures on the weight sensor 404 outside. The load-bearing plate 101 is welded and installed at the bottom end of the storage hopper 1. The feed pipe 103 is communicated with the bottom end of the load-bearing plate 101.

[0023] Please refer to Figures 1-2 In this embodiment, the transmission assembly includes two groups of transmission tables 201 symmetrically arranged. The transmission belt 202 is installed between the two groups of transmission tables 201. The transmission motor 203 is installed outside the transmission table 201 near one end edge. The output end of the transmission motor 203 is connected with the transmission belt 202. The control table 210 is installed away from the transmission motor 203 of one group of transmission tables 201. The transmission belt 202 is a key component for connecting the two groups of transmission tables 201 and carrying the bottles to be injected. It can realize continuous and stable material conveying function. It can convey the bottles to be injected from one station to another station at a uniform speed and stable motion state through cooperation with the transmission motor 203, avoiding the start-stop impact that may occur in the traditional intermittent conveying mode, reducing the vibration and wear of the bottles to be injected and other related components, and ensuring the integrity and stability of the products during conveying, which helps to improve the product quality and production efficiency. Two groups of baffle plates 205 are installed at the top ends of the two groups of transmission tables 201. The observation window 206 is opened outside the baffle plate 205. The mounting column 207 is installed at the top end of the two groups of baffle plates 205. The industrial camera 209 and the power supply 208 are installed at both ends of the mounting column 207.

Two groups of second support columns 204 are symmetrically installed at the bottom ends of the two groups of transmission tables 201. The mounting column 207 provides a stable mounting position for the industrial camera 209 and the power supply 208. The industrial camera 209 located above the transmission table 201 can take pictures or monitor videos in real time for the passing bottles to be injected. It can capture detailed image information of the bottles by using its high-precision imaging capability.

[0024] Please refer to Figure 2 In the embodiment, the auxiliary positioning assembly comprises a mounting table 301, a pneumatic push rod 303 is mounted at the top end of the mounting table 301, a sheath is externally sleeved on the pneumatic push rod 303, a driving cylinder 305 is mounted on one side of the pneumatic push rod 303, the movable end of the driving cylinder 305 is connected with one end of the pneumatic push rod 303 through a universal joint located inside the sheath, the pneumatic push rod 303 plays a key role in directly acting on the bottle to be filled for positioning in the auxiliary positioning assembly, and it can accurately stretch and retract under the power provided by the driving cylinder 305, so as to apply a suitable pushing force on the bottle to be filled placed on the transmission belt 202, so that the bottle to be filled is accurately aligned with the filling nozzle 406 of the feeding and weighing assembly, one end of the pneumatic push rod 303 is fixedly mounted with an auxiliary clamping plate 304, a buffer pad is mounted on the inner side of the auxiliary clamping plate 304, and three-stage supporting columns 302 are welded and mounted at the bottom end of the mounting table 301, the buffer pad mounted on the inner side of the auxiliary clamping plate 304 can play a buffering and protecting role when the auxiliary clamping plate 304 contacts and clamps the bottle to be filled, because the material of the bottle to be filled of the solid beverage is various, some of which may be brittle and easy to break when clamped by external force, the buffer pad can effectively absorb and disperse the pressure applied by the auxiliary clamping plate 304, so as to avoid scratching the surface of the bottle or breaking the bottle due to excessive force.

[0025] In the process of working, first, the solid beverage raw materials are poured into the storage hopper 1, and the first support column 104 on both sides ensures its stable placement. The raw materials enter the feeding and weighing assembly through the guide groove 102 at the top of the feeding pipe 103. When production operation is needed, the transmission assembly is started, and the transmission motor 203 drives the transmission belt 202 to run between the two sets of transmission tables 201, conveying the bottles to be injected below the feeding and weighing assembly. In this process, the baffle 205 prevents the bottles from falling off, and the operator can check the bottle conveying through the observation window 206. The industrial camera 209 monitors the bottle status in real time under the power supply of the power supply 208 and feeds back the information to the control console 210. The control console 210 can control the transmission assembly to ensure accurate positioning of the bottles. Then, the auxiliary positioning assembly works, and the drive cylinder 305 drives the pneumatic push rod 303 through the universal joint to accurately position the bottles to be injected below the injection nozzle 406 under the protection of the buffer pad. At the same time, the feeding and weighing assembly starts the weighing process, and the feeding valve 402 is opened under the action of the electric controller 403. The solid beverage enters the weighing pipe 405 and further acts on the internal stress plate 401. The stress plate 401 deforms, and the weight sensor 404 on one side outside the weighing pipe 405 senses the weight change corresponding to the deformation of the stress plate 401 and transmits the signal to the control system. The control system controls the electric controller 403 according to the preset weight value, and then adjusts the opening of the feeding valve 402. When the preset weight is reached, the feeding valve 402 is closed to stop feeding. Finally, the solid beverage that has been accurately weighed is injected into the bottle to be injected through the injection nozzle 406, completing the weighing and injection process.

[0026] Through the above steps, first, the solid beverage raw materials are placed in the storage hopper 1. When the weighing and injection operation is needed, the transmission assembly is started to convey the bottles to be injected to the specified position, and the auxiliary positioning assembly on both sides starts to work to align the position of the injection nozzle 406. Then, the feeding valve 402 in the feeding and weighing assembly is opened, and the solid beverage in the storage hopper 1 enters the weighing pipe 405 under the action of gravity. As the solid beverage gradually enters the weighing pipe 405, the weight of the solid beverage acts on the stress plate 401, which deforms slightly due to stress. The control system accurately calculates the weight of the solid beverage entering the weighing pipe 405 according to the received electrical signal and compares it with the preset injection amount. When the preset injection weight is reached, the control system will quickly issue an instruction to close the feeding valve 402 and stop the feeding of the solid beverage. At this time, the solid beverage that has been accurately weighed will be accurately injected into the bottle to be injected below the injection nozzle 406 at the bottom of the weighing pipe 405 under the action of gravity, completing the weighing and injection process of the solid beverage.
