Description

Tube needle counting and feeding device

Technical Field

The utility model relates to a pipe needle packing field, concretely relates to reinforced counting assembly that is arranged in the pipe needle letter sorting packing process of acupunture needle.

Background

The acupuncture needles are small and small, and in the packaging process, the acupuncture needles need to be firstly packed into the tube sleeves to form tube needles, then the tube needles are sorted, and finally the tube needles are packed into boxes or bags according to a certain number. In the sorting process of the tube needles, the arrangement and counting of the tube needles are very difficult, feeding, counting and packaging are realized only by manpower, the production efficiency is low, and errors are easy to occur.

In order to overcome the defects of manual sorting, the applicant has developed a sorting wheel to replace manual sorting of the tube pins. A plurality of needle grooves are evenly distributed on the circumferential surface of the sorting wheel in parallel, and the size and the shape of each needle groove correspond to the corresponding tube needle. During feeding, the pipe needles fall into the needle grooves one by one and correspond to the needle grooves one by one, and the pipe needles are driven to rotate through the rotation of the sorting wheel and fall out in order to finish sorting and discharging. This prior art has overcome the problem that traditional manual sorting is inefficient, can promote letter sorting speed by a wide margin, but nevertheless has following not enoughly: in the actual working process of the sorting wheel, the discharge speed of the tube needles is adjusted by controlling the rotating speed of the sorting wheel so as to control the discharge quantity of the tube needles in units; however, the error caused by counting only by the rotating speed of the sorting wheel is large because whether the trough of the sorting wheel is empty or overloaded cannot be judged, and even if the counting is verified by weighing after sorting, the error of actual weighing and counting is large because the weight of a single tube needle is small.

Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
