Description

High precision screw feeder

technical field

The utility model belongs to the technical field of feeders, in particular to a high-precision screw feeder.

Background technique

The screw feeder is a new generation product integrating steady flow conveying, weighing and quantitative control of powder materials; it is suitable for continuous metering and batching of powder materials in various industrial production environments, and is suitable for horizontal or inclined conveying powder , granular and small block materials.

In the process of weighing and feeding glass raw materials, an electric screw feeder is usually used. Some raw materials are in the order of 100 kilograms. The screw diameter and tooth pitch of the screw feeder affect the feeding condition. The material is fast but the precision is low, the diameter and the pitch are small, the feeding is slow but the precision is high.

Utility model content

In order to solve the above problems, the utility model decides to develop a high-precision screw feeder.

A high-precision screw feeder, comprising a bracket, a screw feeder 1, a screw feeder 2, the screw feeder 1 and the screw feeder 2 are installed on the bracket correspondingly up and down, the screw feeder 1 It includes a motor 1, a reducer 1, a feeder shell 1, a screw blade shaft 1, a feeding port 1, an outlet 1, and a feeding port. The screw feeder 2 includes a motor 2, a reducer 2, and a feeder. Shell 2, screw blade shaft 2, feeding port 2, outlet 2; the top of the bracket is provided with a sliding rail, the screw feeder 1 is installed on the upper end of the sliding rail, and the feeding port is set on the feeder casing The bottom end of the body 1; the feeding port corresponds to the feeding port 2 up and down; the diameter and the tooth pitch of the helical blade shaft 2 are smaller than the diameter and the tooth pitch of the helical blade shaft 1.

Further, it also includes an angle adjustment plate and a jack, one end of the angle adjustment plate is movably installed on the support frame of the bracket, the other end of the angle adjustment plate is installed on the top of the jack, and the second screw feeder is installed on the angle adjustment plate. upper end.

Further, the sliding rail includes an upper rail and a lower rail, and the upper rail and the lower rail are matched and arranged.

Further, a detachable sealing plate is installed on the discharge port.

How to use: (1) When the feeding amount is less than 90%, use the large diameter and large pitch of the screw feeder one; (2) When the feeding amount is higher than 90%, use the small diameter and small pitch of the screw feeder two Feeding; open the detachable sealing plate on the feeding port, put the material in the feeder shell 1 into the feeder shell 2, and move the screw feeder 1 to the On the other hand, when the material in the second shell of the feeder is about to be used up, the height of the angle adjustment plate is raised through the jack to help empty the material in the second shell of the feeder.

The beneficial effects obtained by the utility model are as follows: (1) The high-precision screw feeder designed and developed by us can not only use large-diameter and large-pitch feeding when the feeding amount is less than 90%, which ensures fast and efficient, and can After the feeding amount enters 90%, start feeding with small diameter and small pitch, which not only improves the feeding speed but also ensures the feeding accuracy; (2) The setting of the slide rail can move the position of the screw feeder 1 as required; (3) ) The setting of the angle adjustment plate can adjust the angle of the second screw feeder.
