This type of equipment is widely used in many industries, such as food, chemical, pharmaceutical, agricultural materials, etc., and can meet the packaging needs with high weight requirements. With the development of packaging technology, weighing and packaging machines are an important part of it. The improvement of their degree of automation is of great significance to improving overall production efficiency and reducing labor costs. Existing weighing and packaging machines are prone to insufficient material feeding accuracy, which can easily lead to excessive feeding of packaging raw materials, and then exceed the weight of the package. Therefore, in response to this situation, a large-range weighing and packaging machine is proposed. Utility Model Content

The feeding belt delivers the packaged material to the weighing belt and the weighing belt delivers the packaged material to the discharge port for discharge. The feeding machine and the loading machine are conventional conveying equipment, and the power sources of conveyor belts such as the feeding belt and the weighing belt are conventional conveyor belt technologies, so they are not elaborated on. The large-range weighing packaging machine also has a control program and sensor for controlling the stop of the conveyor belt, so the technology is a common technology in this field, so it is not elaborated on.

[0005] Furthermore, the feeding belt consists of a fast feeding belt and a slow feeding belt, the fast feeding belt and the slow feeding belt are arranged in parallel and the width of the fast feeding belt is greater than the width of the slow feeding belt, and both the fast feeding belt and the slow feeding belt are used to feed the weighing belt.

[0006] Furthermore, a guide block is connected between the fast feed belt and the slow replenishment belt. The guide block is in the shape of a triangle with the tip of the guide block facing upward. The guide block guides and distributes the weighed raw materials falling from the feed port to the fast feed belt and the slow replenishment belt.

[0007] Furthermore, the weighing belt is composed of a conveyor belt and a belt scale. Four belt scales are provided and are respectively arranged at the bottom of the conveyor belt. The four belt scales are used to weigh the packaging materials conveyed to the conveyor belt. The conveyor belt and the belt scale constitute a conveyor belt with a weighing function. This technology is a conventional technology in this field, so the principle will not be described in detail.

[0008] The beneficial effects of the utility model are:

[0009] The weighing belt is fed by a fast feeding belt and a slow feeding belt. When the feeding speed reaches the preset value, the fast feeding belt stops feeding and the slow feeding belt starts feeding, thereby effectively preventing the packaging raw material from exceeding the preset packaging weight due to excessive feeding;

[0010] In order to ensure that the fast feed belt and the slow feeding belt can work better, by setting the width of the fast feed belt larger than the width of the slow feeding belt, this design can ensure that the fast feed belt is faster when feeding and the slow feeding belt is more accurate when feeding.
