Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in figures 1-4, the present invention comprises two upright posts 102, a mixing head 103, a mixing head moving track 106, a moving trolley 112, a motor 104 and a belt. The bottom of the two upright posts 102 is provided with a groove and a sliding groove, and the sliding groove is positioned at the bottom of the groove. The sliding grooves are supported on sliding rails 105, and the sliding rails 105 at the bottoms of the two upright posts 102 are parallel and arranged at two sides of the laminating machine. A rack 118 is arranged on the side wall of the sliding rail 105; the side wall of the groove is provided with a driving motor 117, an output shaft of the driving motor 117 is provided with a gear 116, and the gear 116 is meshed with a rack 118. The driving motor 117 can drive the upright post 102 to move along the slide rail 105.
The mixing head moving rail 105 is mounted on the two vertical posts 102 at both ends thereof, respectively. The moving trolley 112 and the motor 104 are arranged on the mixing head moving track 106; the motor 104 is installed at one end of the mixing head moving track 106, the output shaft of the motor 104 is provided with a driving pulley 110, the other end of the mixing head moving track 106 is provided with a driven pulley 115, and two ends of the belt are respectively connected with two ends of the moving trolley 112 to form a closed ring shape.
