Quantitative feeding device for pearl packing line

Abstract

The invention discloses a quantitative material conveying device for a pearl packaging production line and belongs to the technical field of material conveying. The quantitative material conveying device comprises a rack, a control system, an extending-and-contracting air cylinder, a slide block, a rotating shaft, a rotating vane, a discharging pipe, an arc-shaped quantitative pipe, a spiral material conveying pipe and a material box. The control system is mounted at the right side of the rack. The rotating shaft is connected to the upper end of the control system. The rotating vane is connected to the upper end of the rotating shaft and matched with an open groove of the arc-shaped quantitative pipe. The lower end of the arc-shaped quantitative pipe is connected with the upper end of thedischarging pipe. The upper end of the arc-shaped quantitative pipe is connected with the lower end of the spiral material conveying pipe. The upper end of the spiral material conveying pipe is connected with the material box. The extending-and-contracting air cylinder is arranged at the left side of the rack. The slide block is arranged at the upper end of the extending-and-contracting air cylinder. An oil inlet pipe and an oil outlet pipe are arranged at the right side of the extending-and-contracting air cylinder and connected with the control system. The quantitative material conveying device has the beneficial effects of being reasonable in structure, precise in quantification, fast and convenient in material conveying, small in occupied area and applicable to the production line.

Description

technical field [0001] The invention relates to a quantitative feeding device for a pearl packaging assembly line, which belongs to the technical field of material transportation. Background technique [0002] The Chinese patent with publication number CN204872803 disclosed a quantitative feeding device on December 16, 2015. Wherein, a valve chamber is arranged on the feeding pipe, and a rotating assembly is arranged in the valve chamber, including a rotating shaft and a plurality of rotating blades fixed on the rotating shaft, and the plurality of rotating blades divide the valve chamber into a plurality of storage spaces with equal volumes. By turning the rotating blade, the material storage space filled with material turns downward, and the material is delivered through the feeding pipe at the lower end of the valve chamber, and at the same time, the adjacent empty material storage space rotates to the position of the previous valve chamber and is filled with material.

Problems solved by technology

[0005] The problem with the above-mentioned device is that the device automatically falls into the drop hole through the pearl during the rotation of the disc. In the actual production process, the efficiency of automatic induction is low, and it is easy for the pearl to block the drop hole or the plectrum. Another disadvantage is that if the device wants to improve the efficiency of automatic induction, it must replace the large disc and its supporting parts, resulting in the entire device being too large and occupying a large area, which is not suitable for use on pearl packaging lines.
