Quantitative particle material feeding system

Abstract

The invention discloses a quantitative particle material feeding system. The quantitative particle material feeding system comprises a stock bin, a feeding mechanism, a supplementing mechanism, a metering device and a control device. The discharging port of the stock bin is fixedly connected with the feeding port of the feeding mechanism. The feeding mechanism comprises an upper material blocking plate, a lower material blocking plate, an adjustable material blocking plate, an inclined discharging slide way and a flow adjusting mechanism on the discharging slide way, wherein the upper material blocking plate, the lower material blocking plate and the adjustable material blocking plate are arranged in the feeding channel. The flow adjusting mechanism comprises a material baffle and a motor drive mechanism of the material baffle, and the material baffle can be moved in a stepless mode. A mini-type electromagnetic vibration feeder is adopted in the supplementing mechanism and used for accurate feeding, and the feeding port of the mini-type electromagnetic vibration feeder is formed in the discharging slide way of the feeding mechanism. The metering device is a hopper-shaped metering scale, and a scale body of the hopper-shaped metering scale is provided with an independent landing support. A PLC is adopted in the control device. The quantitative particle material feeding system is suitable for moderate and small quantitative feeding of particle materials and particle materials not suitable for being extruded, and the working efficiency and the weighing precision are high. High adaptability is achieved for the size and the ration of the material particles.

Description

technical field [0001] The invention relates to the technical field of automatic quantitative packaging, in particular to a quantitative feeding system for granular materials. Background technique [0002] At present, the quantitative feeding device of granular materials mainly adopts various vibrating feeders, belt conveyors, screw feeders, multi-head computer combination scales, etc. For small and medium quantitative packaging, such as quantitative packaging of about 2 to 6kg, vibration feeding Either the precision is low or the speed is slow; belt conveyors and screw feeders often have low precision; although multi-head computer combination scales have high precision and fast speed, they are expensive and bulky, and are suitable for large quantities of materials that do not change frequently.

Problems solved by technology

[0002] At present, the quantitative feeding device of granular materials mainly adopts various vibrating feeders, belt conveyors, screw feeders, multi-head computer combination scales, etc. For small and medium quantitative packaging, such as quantitative packaging of about 2 to 6kg, vibration feeding Either the precision is low or the speed is slow; belt conveyors and screw feeders often have low precision; although multi-head computer combination scales have high precision and fast speed, they are expensive and bulky, and are suitable for large quantities of materials that do not change frequently. Package

In addition, for granular materials that are not suitable for extrusion, such as shells, metal parts, and seeds, feeding devices with material gates or extrusion mechanisms cannot be used directly. For example, quantitative packaging is required in the production of aluminum shells of electrolytic capacitors. The packaging requirements are: the quantification range is generally 2.0-6.5kg, the accuracy is better than ±0.2%, and the speed is 4-6 packs / min; due to the variety of products, the output varies from time to time, and the quantity may vary each time. Therefore, this It is also required that a single packaging machine has better adaptability, but there is no suitable equipment on the market. At present, the quantitative packaging of aluminum shells of electrolytic capacitors is completely carried out manually. Due to the long working hours, the labor intensity of workers is high, and the measurement The uncertainty of accuracy is large, which directly affects the reputation and economic benefits of the enterprise
