Abstract:
A machine for fusing plastic plates, comprising:a frame (10) having a front end and a rear end,a movable table (20) mounted to the front end of the frame and movable along a longitudinal direction of the frame, the movable table (20) having an underside,a rear compressing device (40, 42) mounted behind the movable table (20) for clamping a first plastic plate (50) with a rear end face (51),a front compressing plate (23) movable in a vertical direction, the front compressing plate and the movable table together clamping a second plastic plate (60) with a front end face (61),a fusion blade (36) for fusing the front end face of the second plastic plate with the rear end face of the first plastic plate,the front compressing plate (23) further including a fixed seat (231) mounted thereon, a cylinder (232) being attached to the fixed seat (231) and having a piston rod (233), a guide plate (234) being secured to the piston rod (233) to move therewith, the guide plate (234) being movable in a horizontal direction upon actuation of the cylinder (232) to abut against the rear end face of the second plastic plate before fusion of the first plastic plate and the second plastic plate, thereby adjusting position of the rear end face (51) of the first plastic plate (50), and further comprising:two spaced screw driving devices (21) secured to the underside of the movable table,two screw rods (211) each having a first end fixed to the frame and a second threaded end coupled to an associated said screw driving device (21),means (24) for driving the screw driving devices (21) to urge the movable table (20) to move along the longitudinal direction of the frame when the first plastic plate (50) and the second plastic plate (60) are tightly clamped, such that the front end face (61) of the second plastic plate (60) and the rear end face (51) of the first plastic plate (50) are in a tight contact before fusion by the fusion blade (36).
