Multi-stage racking machine

Abstract

The invention discloses a multi-stage racking machine which comprises an enclosure, a weighing hopper and a main vibration hopper, wherein a material hopper and a feeding channel are arranged on the main vibration hopper; the multistage racking machine further comprises at least one secondary vibration hopper; the secondary vibration hopper comprises a material hopper and a feeding channel; an outlet of the feeding channel of a first secondary vibration hopper is positioned on the material hopper of the main vibration hopper; and an outlet of the feeding channel of a next secondary vibration hopper is positioned on the material hopper of the first secondary vibration hopper. A plurality of vibration hoppers are designed in the multi-stage racking machine disclosed by the invention and are enabled to have 2-N grades, so that fewer materials fall into the weighing hopper by vibration each time and further the condition that the weighted materials are overweight is effectively avoided. The multi-stage racking machine is very convenient and is especially suitable for racking processes of products such as tea, powder, granules, strips and packaged foods and hardware.

Description

Technical field [0001] The invention belongs to the technical field of packaging machinery, and specifically relates to a multi-stage packaging machine. Background technique [0002] At present, most of the tea sold in the market is mainly in exquisite small packaging, which is convenient for people to buy, carry and store. In the early days, manual weighing was mainly used. The weighing instrument was used to weigh it and then packaged. This was not only time-consuming, labor-intensive, and efficient. Low, and the measurement accuracy is not high. For this reason, after research and development and design by researchers, there are now a variety of tea dispensing machines on the market, most of which are mainly used for dispensing tea, and can also be used for dispensing other items. Most of the existing dispensing machines include vibrating buckets, Weighing hopper and control system. When the material is put into the vibrating hopper and the rated weight is set, the vibrating ...

Problems solved by technology

[0002] At present, most of the teas sold on the market are in exquisite small packages, which are convenient for people to buy, carry and store. In the early days, manual weighing was mainly used, and packaging was done after weighing with weighing instruments, which was not only time-consuming, laborious and efficient. low, and the measurement accuracy is not high

For this reason, through researcher's research and development design, various tea packing machines have appeared on the market today, mostly mainly for packing tea, and can also be used for packing other items. Weighing hopper and control system, when the material is put into the vibrating hopper and the rated weight is set, the vibrating hopper vibrates and feeds to the weighing hopper. When the material in the weighing hopper reaches the rated weight, the vibrating hopper continues to vibrate and feed, and the vibrating hopper The material in the feeding channel vibrates into the weighing hopper, but the feeding channel has a certain width, and a lot of material will fall into each vibration, resulting in overweight materials in the weighing hopper. If the feeding channel is set very narrow, it may The above situation can be alleviated, but the overweight phenomenon cannot be completely avoided, and the narrow feeding channel is not conducive to the rapid passage of materials and reduces work efficiency. so much inconvenience
