Description

Power transmission mechanism of centrifugal feeder

This creation relates to a power transmission mechanism of a feeder, especially a power transmission mechanism that can drive two mechanisms to rotate and feed materials through a single power unit.

When the material manufacturing industry wants to transfer a large number of semi-finished blanks that have not been formed to the next processing station or equipment of the production line for processing, they are usually conveyed through the vibrating feeder; however, the prior art vibrating feeder is roughly divided into Vibrating feeder and centrifugal feeder, which mainly use the principle of vibration to move the transported parts, the transmission process will produce high decibel noise, which is easy to cause hearing damage to the workers in the field. The feeder is rotated by a turntable to transport the material to the track for centrifugal force to produce the feed. The existing centrifugal feeder, as disclosed in the Taiwan invention patent certificate number I546239 (as shown in Figure 1), the case The feature is that the double motor drives the turntable and the feed tray respectively, and generates a rotating centrifugal force for feeding.

However, using dual motors to drive the turntable and feed tray separately results in higher costs, and the rotation speed of the turntable and feed tray must be adjusted individually. Slowly adjust the two motors to achieve the desired speed. One hand adjusts the motor of the turntable, while the other hand adjusts the motor of the feed tray, and it is not easy to operate and adjust, and it is still plagued by the convenience of adjustment; secondly, the use of dual motors to drive the rotation, which consumes more power when the electric load is loaded, and the configuration It is also relatively complicated, so it is easy to cause cost increase and large energy consumption, so the traditional centrifugal feeder adopts a dual motor configuration The design does not meet the current economic requirements.

The purpose of this creation is to provide a power transmission mechanism used in a centrifugal feeder, which mainly uses a single motor to connect the throwing tray and the feeding tray through the transmission assembly, which can drive the throwing tray and the feeding tray to produce the same direction of rotation and different Rotation speed, so that the material is sent to the feed tray by the swing of the feed tray, and then the feed tray is inclined downward, so that the material will be fed against the surrounding material wall to reduce the noise and noise in the feeding process. Reduce costs and improve operational efficiency.

In order to achieve the above-mentioned creative purpose, the power transmission mechanism of the feeder disclosed in this creation mainly includes a feed tray group, a throwing tray group, a surrounding material wall, a transmission component and a power unit; wherein the feed tray group is located at A main body includes a main body, the main body is a cylindrical structure with a receiving space, and a material rail extends outward from the top edge of the cylinder, and the material rail is set to a downward tilting type; The throwing tray group has a throwing tray, which is obliquely arranged in the receiving space of the feeding tray group, and the outer edge part of the top of the throwing tray is adjacent to the placing rail of the feeding tray group, and is convex at the lower edge of the tray surface A drive shaft is extended and rotates synchronously with the material throwing disc; a surrounding material wall is looped outside the material placing rail of the material feeding disc group and forms a gap with the material placing rail, and a material discharging track is arranged at the tangent end of the material placing rail; The transmission assembly includes a first annular chain horizontally arranged at the bottom of the cylinder structure of the feeding tray group, and a first gear disc arranged on the lower edge transmission shaft of the throwing tray of the throwing tray group; the power unit, and The drive shaft at the lower end of the throwing plate is arranged in parallel, including a motor and a second gear plate fixed on the rotating shaft of the motor and connected to the first ring chain at the bottom of the feeding plate set at an oblique angle and connected to the drive shaft at the lower end of the throwing plate A gear disc and the second ring chain of the pinion disc on the motor shaft are connected and configured through the transmission component and the power unit, which can drive the feed disc group and the throw disc group to rotate in the same direction.

Among them, the first gear plate on the motor shaft can also be replaced by a helical gear, whereby Engage the first endless chain at the bottom of the feed tray group to provide power to drive the feed tray to rotate.

Wherein, the outer edge of the second gear disc on the rotating shaft of the motor forms an inclination structure that is horizontally meshed with the first endless chain at the bottom of the feed tray group, which is enough to match the rotation of the feed tray.

The technical core of this creation lies in the design of the transmission mechanism. How to use a single motor to connect the throwing tray and the feeding tray through the transmission component, and drive the throwing tray and the feeding tray to produce different speeds of rotation. When the spinning tray rotates, it will be shifted to the top, and then sent to the feeding rail of the feeding tray group, and through the downward tilting of the feeding rail, the material keeps sliding against the surrounding wall and is rotated by the feeding rail Drive it to the discharge track in order to complete the feeding moving parts, and according to this, the staff only needs to adjust the speed of a single motor, and the diameter of the gear disc is used to control the difference between the rotation speed of the throwing disc and the feeding disc, thereby reducing costs and improving Operational efficiency.
