[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] like Figure 1-Figure 3 As shown, the material weighing system includes a cache unit, a weighing unit, a memory unit and a conveying unit, and the cache unit, weighing unit, memory unit and conveying unit are arranged in sequence from top to bottom on the support frame 1. The material passes through the loading assembly and falls into the weighing unit through the cache unit. The weighing unit weighs the material and then falls into the memory unit. The memory unit is used to distribute the material to the conveying unit. The bottle to be filled is located at the outlet end of the conveying unit. The material enters the bottle to be filled through the conveying unit. A plurality of rollers 5 are installed under the support frame 1. The support frame 1 can slide relatively through the rollers 5. The cache unit is used to cache the material to be filled and then falls into the weighing unit to weigh the material. The memory unit is a storage device from the bottom of the material to the conveying unit. After the material in the plurality of memory units is balanced, it is uniformly lowered to the conveying unit for filling so as to meet the filling weight requirements. At the same time, the buffer unit, weighing unit and memory unit can be used to continuously and quantitatively weigh and fill the material.

[0022] In order to meet the needs of counterweight filling of multiple units, the cache unit includes multiple cache buckets 2, the weighing unit includes multiple weighing buckets 3, and the memory unit includes multiple memory buckets 4. A cache bucket 2 and a memory bucket 4 are respectively set at both ends of each weighing bucket 3. The structures of the cache bucket 2, weighing bucket 3 and memory bucket 4 are the same and are all funnel-shaped structures.

[0023] The small mouth ends of the buffer bucket 2, weighing bucket 3 and memory bucket 4 are respectively provided with a plug plate, and a first linear module is installed at one end of each plug plate, and the first linear module is fixedly installed on the support frame 1. The plug plate is used to open and close the passage of the small mouth end so that the material can be transported in the buffer bucket 2, weighing bucket 3, memory bucket 4 and conveying unit. A torque sensor is installed on the first linear module below the weighing bucket 3. The torque sensor is used to detect the quality of the material in the weighing bucket 3 and transmit it to the controller. During implementation, if the two plug plates of the weighing bucket 3 and the memory bucket 4 are respectively in the closed state, the external material conveying device corresponding to this route stops rotating to prevent excessive storage of material in the buffer bucket 2, causing poor filling line.

[0024] A conveying unit is arranged below the memory unit, and the conveying unit includes a first belt 61. The first belt 61 is equipped with a driving wheel and a driven wheel. The driving wheel and the driven wheel rotate synchronously through the first belt 61. One end of the driving wheel is connected to the output end of the first motor. The first motor is fixedly mounted on the support frame 1. A discharge hopper 62 is arranged at one end of the first belt 61. The bottle to be filled is located below the discharge hopper 62. The first motor is used to drive the driving wheel and the driven wheel to rotate, thereby realizing the transfer of materials into the bottle to be filled.

[0025] In order to improve the filling efficiency, the conveying unit includes two first belts 61 arranged in opposite directions, and a first belt 61 is arranged on both sides of the discharge hopper 62, and each first belt 61 is arranged at an angle. The discharge hopper 62 is located below each first belt 61. The same conveying unit includes two discharge hoppers 62, and the two discharge hoppers 62 are arranged parallel to each other. A discharge swing hopper 63 is provided on the support frame 1, and the discharge swing hopper 63 is located above each first belt 61. The outlet end of the discharge swing hopper 63 can swing above each discharge hopper 62, and the discharge swing hopper 63 is used to distribute the material into a discharge hopper 62.

[0026] A first support rod and a second support rod are respectively provided on the unloading swing bucket 63, a second linear module 64 is installed on the support frame 1, a first baffle 65 is provided on the second linear module 64, a second baffle 66 is installed on the movable end of the second linear module 64, and an opening groove 67 is respectively provided on the first baffle 65 and the second baffle 66. The first support rod and the second support rod are respectively located in an opening groove 67. The second linear module 64 can push the second baffle 66 to slide linearly, so that the second support rod moves in an arc along the axis of the first support rod, and the opening groove 67 is used for the second support rod to move in the vertical direction.

[0027] A photoelectric sensor 68 is installed on the second linear module 64. The photoelectric sensor 68 is used to detect whether there is material in the discharge hopper 62 or whether there is material blockage in the discharge hopper 62. The photoelectric sensor 68 is a prior art. The signal of the photoelectric sensor 68 is connected to the controller. When the material enters the discharge hopper 62 through the first belt 61, the photoelectric sensor 68 can detect the presence of the material and transmit the signal to the controller so that the controller can record the completion of filling.

[0028] The control method of this embodiment is controlled by a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. This article is mainly used to protect mechanical devices. The control method and circuit connection are not explained in detail in this article.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
