[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] like Figure 1-Figure 3 As shown, the material weighing system includes a weighing unit and a conveying unit respectively arranged on a support frame, and the weighing unit is located above the conveying unit, and a plurality of rollers are installed under the support frame. The support frame can slide relatively through the rollers, and the conveying unit includes a first belt. The first belt is equipped with a driving wheel and a driven wheel. The driving wheel and the driven wheel rotate synchronously through the first belt, and one end of the driving wheel is connected to the output end of the first motor. The first motor is fixedly installed on the support frame, and a discharge hopper is provided at one end of the first belt. The support frame can slide relatively through the rollers so as to move the weighing system to the working position, which is convenient for on-site adjustment, and the material can be accurately conveyed to the filling position through the conveying unit, thereby improving the filling quality and efficiency of the product.

[0023] The weighing unit includes a cache unit, a weighing unit and a memory unit, and the cache unit, the weighing unit, the memory unit and the conveying unit are arranged in sequence from top to bottom on the support frame. 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. Multiple rollers are installed under the support frame, and the support frame can slide relatively through the rollers. 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 multiple memory units is weighed, it is uniformly lowered to the conveying unit for filling to meet the filling weight requirements. At the same time, the buffer unit, the weighing unit and the memory unit can be used to continuously and quantitatively weigh and fill the material.

[0024] In order to meet the needs of counterweight filling of multiple units, the cache unit includes multiple cache buckets, the weighing unit includes multiple weighing buckets, and the memory unit includes multiple memory buckets. A cache bucket and a memory bucket are respectively set at both ends of each weighing bucket. The structures of the cache bucket, weighing bucket and memory bucket are the same and are all funnel-shaped structures.

[0025] The small mouth ends of the buffer bucket, weighing bucket and memory bucket are respectively provided with a plug plate, and a first linear module is installed at one end of each plug plate. The first linear module is fixedly installed on the support frame. 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, weighing bucket, memory bucket and conveying unit. A torque sensor is installed on the first linear module below the weighing bucket. The torque sensor is used to detect the quality of the material in the weighing bucket and transmit it to the controller. During implementation, if the two plug plates of the weighing bucket and the memory bucket are respectively in the closed state, the external material conveying device corresponding to this route stops rotating to avoid excessive storage of material in the buffer bucket, which causes a blocked filling line.

[0026] A conveying unit is arranged below the memory unit, and in order to improve the filling efficiency, the conveying unit includes two first belts arranged opposite to each other, a first belt is arranged on both sides of the discharge hopper, and each first belt is arranged at an angle, and the discharge hopper is located below each first belt. The same conveying unit includes two discharge hoppers, and the two discharge hoppers are arranged parallel to each other. A discharge swing hopper is arranged on the support frame, and the discharge swing hopper is located above each first belt. The outlet end of the discharge swing hopper can swing above each discharge hopper, and the discharge swing hopper is used to distribute the material into a discharge hopper.

[0027] A first support rod and a second support rod are respectively provided on the unloading swing bucket, a second linear module is installed on the support frame, a first baffle is provided on the second linear module, a second baffle is installed on the movable end of the second linear module, open grooves are respectively provided on the first baffle and the second baffle, the first support rod and the second support rod are respectively located in an open groove; the second linear module can push the second baffle to slide linearly, so that the second support rod moves in an arc along the axis of the first support rod, and the open groove is used for the second support rod to move in the vertical direction.

[0028] A photoelectric sensor is installed on the second linear module. The photoelectric sensor is used to detect whether there is material in the discharge hopper. The photoelectric sensor is an existing technology. The photoelectric sensor signal is connected to the controller. When the material enters the discharge hopper through the first belt, the photoelectric sensor can detect the presence of the material and transmit the signal to the controller so that the controller can record the completion of filling.

[0029] 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.

[0030] 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.
