Detailed Description

A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The spring grinding feeding device shown in fig. 1 comprises a feeding roller 1, a guide device 2 and a beat device 3 which are communicated in sequence; the feeding roller is respectively provided with a feeding port 11 and a discharging port 12 at two axial ends, the feeding port and the discharging port are connected through an obliquely arranged V-shaped track 13, and a vibration motor 14 is arranged on the lower end face of one side, close to the discharging port, of the V-shaped track; the guide device adopts a plurality of feeding hoses 21 connected with the discharge hole, and outlets of the feeding hoses are vertically downward; the metronome enables the springs to fall into the grinding mechanism 4 in an orderly manner.

The springs are easy to wind due to the pitch, the spring feeding efficiency is greatly influenced, the winding of the springs is reduced by the vibration effect of the vibration motor 14, and in order to better guide and disperse the spring conveying and avoid the spring accumulation and blockage, the blowing device 22 is arranged at the inlet of the feeding hose; and an empty material alarm device 23 is also arranged outside the body of the feeding hose, and when no spring is used for conveying in the hose for a long time, an alarm is given.

The grinding mechanism 4 according to the preferred embodiment includes a first grinding wheel 41, a grinding disc 42, and a second grinding wheel 43 coaxially arranged in the vertical direction, and the grinding disc is uniformly provided with a plurality of through holes 44 for placing springs in the radial direction. In order to ensure the precision and the efficiency of feeding, the grinding disc is provided with a positioning pin 45, the grinding disc can stop after rotating for a fixed angle according to the frequency of the beat device 3, the beat device controls a group of springs to fall into the through holes after stopping every time, and the diameter of each through hole is 0.4-0.5mm larger than the outer diameter of each spring. During grinding, the rotating directions of the first grinding wheel and the second grinding wheel are consistent and opposite to the rotation direction of the grinding disc, and the spring grinding efficiency is greatly accelerated by grinding the two surfaces simultaneously.

In a specific use, the springs enter from the feeding port 11 of the feeding roller through the V-shaped track 13, then slide into the guide device 2 through the V-shaped track and under the action of the vibrating motor, and then vertically and downwards enter the beating device 3 through the feeding hose, and then the grinding disc stops after rotating for a certain angle according to the frequency of the beating device, and the beating device conveys a group of springs into the through holes 44 of the grinding disc, and the operation is repeated until the through holes on the grinding disc are filled with the springs.

The preferred embodiment the metronome in be provided with two bolts about, go up the bolt and insert the spring of metronome when the spring will pay off in the middle of, lower bolt withdraws from the metronome again and makes the spring of bottommost fall into the mill downthehole, lower bolt returns earlier to the metronome after the pay-off, goes up the bolt and withdraws from the metronome to this operation of relapseing makes the spring get into the mill in an orderly manner.

The above-mentioned embodiments are only to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
