Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of metering equipment, and specifically relates to a weight gain type metering equipment. BACKGROUND

[0002] The weight gain type batch batching system is a batching system commonly used in the powder industry, which is composed of a feeding mechanism, a weighing hopper, a weighing module and a control system. The feeding mechanism is controlled by the feedback signal of the weighing module. When the target weight is reached, the feeding mechanism stops working, and the batching work is completed. Generally speaking, for weight gain batch batching of multiple materials, one weighing hopper can be shared. Each material is fed to the weighing hopper through its own feeding mechanism. This method can meet the batching of multiple raw materials with one set of weighing system, thereby saving costs.

[0003] In the prior art, a multi-component weight gain type metering equipment (CN220583575U) is provided. When multiple materials are added for weighing and feeding, the second servo motor works, the second servo motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade to rotate. The stirring blade can mix the materials in the discharge pipe to improve the uniformity of the materials in the discharge pipe and reduce the mixing difficulty when adding materials. When the large hopper bin is discharged, the first servo motor works, the first servo motor drives the rotating disc to rotate, the rotating disc drives the arc-shaped teeth on it to rotate, and when the arc-shaped teeth are disengaged from the rack, the spring reset force pushes the limiting block, the limiting block pushes the square rod, and the rubber head at one end of the square rod knocks the sidewall of the large hopper bin to assist the discharge of the large hopper bin and ensure the discharge effect. However, in the prior art, the small hopper bin is located in the middle of the large hopper bin. When the main material with a heavy weight is poured into the large hopper bin, part of the main material may fall into the small hopper bin. When the auxiliary material with a light weight is poured into the small hopper bin, part of the auxiliary material may also fall into the large hopper bin, which requires time to remove the wrong main material or auxiliary material, thereby affecting the normal use of the metering equipment.

[0004] Therefore, the skilled person in the art proposes a weight gain type metering equipment to solve the problems in the above background. UTILITY MODEL CONTENTS
