Detailed Description
Referring to fig. 1 and 2, the utility model relates to a punching plate assembly of an improved plastic bag punching machine, which comprises a punching plate 2, a cover body 1, a supporting plate 13 and a driving device, wherein two round holes 12 for placing the round punching plate 2 are arranged on the upper surface of the cover body 1, and the supporting plate 13 is arranged below the cover body 1, and the supporting plate 13 is fixed with a frame 9; a driving device is arranged below the supporting plate 13, and is characterized in that the cover body 1 is arranged on the frame 9 through a two-dimensional sliding mechanism, and the driving device drives the cover body 1 to do circular motion on a horizontal plane; an inner peripheral tooth 11 is provided on the inner peripheral edge of the circular hole 12; an outer peripheral tooth 21 corresponding to the inner peripheral tooth 11 is provided on the outer periphery of the circular punch plate 2, and the diameter of the tip outline of the outer peripheral tooth 21 is slightly smaller than the diameter of the tip outline of the inner peripheral tooth 11.
The driving device comprises a motor 10, an output shaft 101 of the motor 10 is connected with one end of a crank 3, and the other end of the crank 3 is rotatably connected with the cover body 1 (such as through a bearing) through an eccentric shaft 4. In the middle of the support plate 13, an eccentric shaft rotation hole 14 is provided, which leaves room for the rotation of the eccentric shaft 4 (therefore, the radius of the eccentric shaft rotation hole 14 should be larger than the length of the crank 3).
The two-dimensional sliding mechanism comprises a transverse shaft 5, transverse sliding blocks 6, a longitudinal shaft 7 and longitudinal sliding blocks 8, two ends of the two mutually parallel transverse shafts 5 are supported on a frame 9, and the transverse sliding blocks 6 are slidably arranged on the transverse shafts 5; two ends of the longitudinal shaft 7 are connected between a corresponding pair of transverse sliding blocks 6, a longitudinal sliding block 8 is slidably arranged on the longitudinal shaft 7, and the two longitudinal shafts 7 are parallel to each other; the underside of the cover 1 is fixed on a longitudinal slide 8.
