The utility model discloses a distance-adjustable
cantilever type automatic box nailing
machine which comprises a conveying belt, a
portal frame is fixedly installed on the outer wall of the conveying belt, a
hydraulic cylinder is fixedly installed in the center of the top in the
portal frame, a box body is arranged at the lower end of the
hydraulic cylinder, a
threaded rod is arranged at the position, close to the bottom, in the box body, and the
threaded rod is connected with the
portal frame. A motor is fixedly installed at the position, close to the center, of the top in the box body, and the motor is fixedly connected with an output shaft through the output end on one side of the motor. According to the distance-adjustable
cantilever type automatic box nailing
machine, through the design of a
threaded rod, a motor, a transmission wheel, a guide rod, a guide block, threaded plates, an extension rod, a pointer and scale marks, the motor drives the threaded rod to rotate, synchronous movement of the two threaded plates on the threaded rod is achieved according to the threaded connection principle, then the distance between the two nailing devices is accurately adjusted, and the nailing efficiency is improved. The transmission mode is stable and reliable, the adjusting precision is high, and the accuracy of nailing operation is ensured.
