Problems solved by technology
[0002] At present, most weighing and feeding devices use gravity drop or conveyor belt to transport raw materials into the hopper. Gravity drop transportation is limited by the height of the device, and the installation must have a height difference. Scattering; when feeding and weighing, they are all the same material, and it is impossible to mix and pack different kinds of raw materials, which increases the complexity of the production process

Embodiment Construction
[0015] In order to make the implementation technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.
[0016] Such as figure 1 as shown,
[0017] A method for controlling multi-component weighing and feeding, comprising a hopper 1 and a material suction device connected to the hopper 1, a weighing device 2, a multi-component feeding device and a valve 3, the material suction device, the weighing device, the multi-component Component feeding devices and valves are electrically connected to the control system, wherein:
[0018] The material suction device includes a suction port 4, which communicates with the external air suction device to form a negative air pressure in the hopper 1. The side end of the hopper 1 is provided with a suction port 5, and the suction port 5 is connected to multiple sets of tubes through a hose 6. The feed...

The invention provides a multi-component weighing feeding control method, wherein the method includes a hopper and a suction device, a weighing device, a multi-component sending device and a valve which are connected with the hopper. The suction device makes negative pressure generated in the hopper for material suction, avoids the sprinkling of raw materials, and alleviates the blockage of a conveying pipeline; the multi-component sending device realizes the simultaneous supply of different raw materials and realizes mixing of the raw materials while conveying. When the weight of a componentin the hopper reaches the system set value + / - the system error value, the feeding of a next component is automatically carried out; when a solenoid valve is opened frequently and the raw materials cannot be detected still or the weight of the raw materials entering the hopper is more than the sum of the system set value and the system error value, the feeding of a next component is automaticallycarried out. At the time, the system can automatically calculate, compensate and adjust the weight of other components to ensure that the proportion of the components in the hopper conforms to the system set value according to the weight information of the components entering the hopper and the proportion value set in the system.
Description
technical field [0001] The invention relates to the technical field of weighing and feeding, in particular to a method for controlling multi-component weighing and feeding. Background technique [0002] At present, most weighing and feeding devices use gravity drop or conveyor belt to transport raw materials into the hopper. Gravity drop transportation is limited by the height of the device, and the installation must have a height difference. Scattering; when feeding and weighing, they are all the same material, and it is impossible to mix and pack different kinds of raw materials, which increases the complexity of the production process. Contents of the invention [0003] The technical problem solved by the present invention is to provide a multi-component weighing and feeding control method to solve the problems raised in the above-mentioned background technology. [0004] The technical problem solved by the present invention is realized by the following technical solut...
