[0002] Most of the feeding mechanisms used in existing technologies use vibration plates, in which the vibration plate automatically and orderly arranges the disordered steel parts according to the vibration, and undergoes a series of track screening or posture changes during the rising process. The parts can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing. Its working purpose is to automatically and orderly arrange the disordered workpieces through vibration, and accurately transport them to the next process, which is used for product arrangement, selection, inspection, counting and packaging, etc. It is a necessary feeding machine for industrial automation machinery and is widely used in light industrial machinery, hardware industry, plastic connectors, fitness equipment and other manufacturing industries.

[0003] There are many types of such vibration plates on the market today, which can basically meet people's needs, but there are still certain problems. The existing vibration plates of this type use vibration to discharge materials when in use, so it is difficult to avoid generating large noises. In addition, the vibration discharge efficiency is slow, the feeding is unstable, the oily product slips, and the material cannot be loaded, and high-speed feeding cannot be achieved; in addition, the vibration discharge is easy to scratch the product and damage the fed product. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the utility model aims to provide a feeder with low feeding noise, fast feeding speed, high efficiency, and no vibration of the feeding workpiece.

[0005] To achieve the above-mentioned purpose, the utility model is a new centrifugal disc feeder, comprising a frame, an inner disc and an outer disc arranged on the frame, the outer disc is provided with a containing space for accommodating an external workpiece, the inner disc is placed in the containing space, the frame is provided with a first driving mechanism and a second driving mechanism, the first driving mechanism drives the inner disc, the inner disc is connected to the frame via the first driving mechanism, the second driving mechanism drives the outer disc, the outer disc is connected to the frame via the second driving mechanism; an output outer edge is arranged at the end edge of the outer disc; the external workpiece is placed on the inner disc, the first driving mechanism drives the inner disc to rotate, the workpiece moves to the output outer edge under the action of centrifugal force, the second driving mechanism drives the outer disc to rotate, and sends the workpiece out of the feeder. The utility model drives the workpiece on the inner disc to perform centrifugal motion through the rotation of the inner disc, the workpiece moves to the output outer edge under the action of centrifugal force, reduces the noise generated during the feeding process, realizes high-speed feeding, and improves production efficiency; at the same time, the workpiece feeding does not need to experience vibration, which solves the problem of damage to the workpiece due to vibration.

[0006] Furthermore, the inner disk is tilted relative to the outer disk, the central axis of the inner disk forms an angle with the central axis of the outer disk, and the upper end surface of the inner disk is flush with the output outer edge. When the inner disk rotates, the workpiece moves to the upper end surface of the inner disk under the action of centrifugal force, and the workpiece located on the upper end surface is transported to the output outer edge under the action of centrifugal force. The inner disk is tilted relative to the outer disk so that the workpiece located at other positions falls onto the inner disk under the action of gravity, so that the workpieces are neatly arranged on the output outer edge.

[0007] Furthermore, the angle between the center axis of the inner disk and the center axis of the outer disk is in the range of 5°-10°. The larger the inclination angle of the inner disk, that is, the larger the angle between the center axis of the inner disk and the center axis of the outer disk, the more workpieces can be stored at the lowest point of the inner disk, and the fewer workpieces are transported to the outer edge of the output; the smaller the angle, the fewer workpieces can be stored at the lowest point of the inner disk, and the more workpieces are transported to the outer edge of the output, which is easy to cause workpiece accumulation. Therefore, the angle range between the center axis of the inner disk and the center axis of the outer disk is selected according to actual conditions.

[0008] Furthermore, the first driving mechanism includes a first motor and a first transmission shaft. The first motor is mounted on the frame, and the output end of the first motor is connected to the inner disk via the first transmission shaft. The rotation speed of the inner disk is controlled by the first motor to adapt to the centrifugal force required by different workpieces. The first transmission shaft increases the stability of the movement and avoids large vibrations, thereby solving the problem of damage to the workpiece due to vibration.

[0009] Furthermore, the second driving mechanism includes a second motor, a second transmission shaft and a transmission assembly. The second motor is mounted on the frame. The output end of the second motor is connected to the second transmission shaft via the transmission assembly. The second transmission shaft is connected to the outer disk. The rotation speed of the outer disk is controlled by the first motor, thereby adjusting the rotation speed of the outer disk and the speed of the material discharge. The second transmission shaft increases the stability of the movement and avoids large vibrations, thereby solving the problem of damage to the workpiece due to vibration.

[0010] Furthermore, the second transmission shaft is provided with a through hole, the first transmission shaft passes through the through hole and is fixedly connected to the inner disk, and the second transmission shaft is connected to the first transmission shaft via a bearing. The first transmission shaft and the second transmission shaft are made into an integrated structure, which saves equipment space and reduces equipment costs.

[0011] Furthermore, the transmission assembly includes a first synchronous wheel connected to the output end of the second motor, a second synchronous wheel and a synchronous belt, the second synchronous wheel is fixedly connected to the outer disk, and the second synchronous wheel is connected to the second transmission shaft via a bearing. The synchronous wheel adopts the gear transmission principle, and the gear tooth design can ensure a precise transmission ratio, making the transmission process more stable and reliable; at the same time, the synchronous belt can play a certain role in shock absorption and noise reduction during the transmission process, reducing the vibration and noise during the mechanical transmission process.

[0012] Furthermore, the outer disk is provided with a guide fixture, which is used to screen the workpieces on the outer edge of the output and sort the workpieces and transport them to the external conveyor belt. The guide fixture between the outer disk and the external conveyor line is designed according to the size, height and motion trajectory of the workpiece, which can improve the conveying efficiency of the workpiece and guide the workpiece to the queue on the conveyor line.

[0013] Furthermore, the inner disk and the outer disk are made of high molecular weight polyethylene. High molecular weight polyethylene has high strength and rigidity, and low density to avoid scratching the workpiece. Due to its high molecular weight and chain structure, high molecular weight polyethylene has good wear resistance and fatigue resistance, which increases the service life.

[0014] Furthermore, a conical disk is provided on the side of the inner disk away from the outer disk, so that the workpiece can be kept in circumferential motion close to the outer circumferential surface during rotation, thereby increasing the stability of the workpiece movement on the inner disk and preventing the workpiece from passing directly through the center of the inner disk.

[0015] The beneficial effects of the utility model are as follows: the utility model drives the workpiece on the inner disk to perform centrifugal motion through the rotation of the inner disk, and the workpiece moves to the outer edge of the output under the action of centrifugal force, thereby reducing the noise generated during the feeding process, achieving high-speed feeding, and improving production efficiency; at the same time, the workpiece does not need to experience vibration when feeding, thus solving the problem of damage to the workpiece due to vibration; when the inner disk rotates, the workpiece moves to the upper end surface of the inner disk under the action of centrifugal force, and the workpiece located on the upper end surface is transported to the outer edge of the output under the action of centrifugal force, and the inner disk is inclined relative to the outer disk so that the workpiece located at other positions falls onto the inner disk under the action of gravity, so that the workpiece is neatly arranged on the outer edge of the output; The first transmission shaft and the second transmission shaft are made into an integrated structure, which saves equipment space and reduces equipment costs. The bearing increases the stability of movement and avoids large vibrations, solving the problem of workpiece damage due to vibration.
