A Safe Nail Roller

Abstract

Currently, movable parts in a coil nail device of a coil nail machine can not be installed in a protecting cover, and the phenomenon that operators are hurt frequently occurs. According to the safe coil nail device of the coil nail machine, non-universal elements such as a duplex slide cylinder support, a bearing support, a speed reduction motor support, the protecting cover, a coupler and a coil nail shaft are manufactured through universal elements such as a duplex slide cylinder, a direct-current speed reduction motor, a constant-current drive circuit of the direct-current speed reduction motor and a bearing, then the safe coil nail device which is simple in structure, stable in running, small in size, capable of producing high-quality coil nails and free of hurting the operators can be assembled, and the safe coil nail device is used for replacing conventional coil nail devices which are widely used at present.

Description

technical field [0001] The invention relates to a nail curler on a nail curler. technical background [0002] The nail coiler on the nail coiler has two kinds of structures at present, and one of them is to adopt sliding platform structure (China Taiwan), and another kind is to adopt hollow shaft cylinder structure (China mainland). [0003] The nail coiler with a sliding platform structure is composed of a cylinder, a dovetail sliding platform, a small deceleration AC motor, a pulley and a belt, a nail coiling shaft, a small deceleration AC motor and a belt pulley bracket, a nail coiling shaft bracket and a nail coiler baffle plate; The cylinder block, the lower end of the dovetail sliding platform, and the baffle plate of the nail curler are fixedly installed on the nail rolling machine body; the piston in the cylinder is connected with the upper end of the dovetail sliding platform through the piston shaft; the small deceleration AC motor, the pulley bracket and the nail ...

AI Technical Summary

Problems solved by technology

The main disadvantages of this type of nail coiler are: 1. The driving motor is fixedly installed on the movable platform through the belt pulley. At the same time, in order to ensure the stability of the nail coil shaft, the nail coil shaft support must be provided, resulting in many parts installed on the sliding platform. The size is large, the center of gravity is high, and the protective cover cannot be installed, so the safety of the operation cannot be guaranteed; 2. Because there are many parts installed on the sliding platform, the volume is large, the center of gravity is high, and the sliding platform is pushed by the cylinder at one end, resulting in the nail roll shaft Poor stability and large vibration, resulting in poor coil quality; 3. If you need to adjust the size of the nail, you can only adjust the distance between the baffle plate of the nail coiler and the sliding platform, which makes the adjustment inconvenient; 4. The sliding platform The stroke is fixed, and the empty stroke is too large when processing small nails, which will affect the stability and working efficiency of the ring nail shaft.

The main disadvantages of this type of nailer are: 1. Because the workpiece is pushed out of the nail shaft by the cylinder through the nail removal process, it is easy to cause the phenomenon of beating hands; The relative movement of the hollow disc is prone to pinching fingers; 3. During the nail rolling process, the rotational speed of the nail shaft changes greatly. In order to prevent the AC motor from burning out at low speed, a belt drive must be installed to cause the drive The torque is unstable and insufficient, and wastes energy; 4. In addition to the rotational movement between the shaft stud shaft and the hollow shaft of the cylinder, there is also a relative movement from left to right. Therefore, it is impossible to install a bearing that fixes the shaft stud shaft in the hollow shaft of the cylinder. The nail shaft is severely worn in the hollow shaft of the cylinder, which not only wastes energy, reduces the service life of the nailer, but also increases the vibration of the nail shaft, resulting in low quality nails
