1. The machine adopts a left-right push-pull structure; the mounting parts can be adjusted according to needs, suitable for left-handed or right-handed operation; 2, the machine adjusts and positions the height of the rear main frame. The rear main beam is adjusted up and down according to the height of the substrate by adjusting the post screw. The up and down adjustment range is 200 mm. It can print cylindrical and conical products with a diameter of 170 mm.3. The printing frame of the substrate is designed to move forward and backward, and the three fixed aluminum strips at the bottom are directly installed on the base. The aluminum strip can move 290 mm from side to side; Positioning bracket mounting strip. The three mounting strips can be moved left and right as needed, and they are locked in 19 U-shaped holes at the front and back of the base (each hole is 15 mm apart) to ensure accurate positioning of the mounting strips.Displacement of the mounting bar: Loosen the two screws of the mounting bar, push the mounting bar to the rear of the machine to the long hole, move the mounting bar to the left and right, and then move the mounting bar to the fixed U-shaped slot, tighten the two screws Positioning is complete.4, three sets of substrates are used to place the rollers, which are metal bearing rollers (diameter 19 mm); nylon bearing rollers (diameter 25 mm); plastic bearing rollers (diameter 50 mm), which can be replaced by users as needed. Three rollers can be installed on the main frame and the accessory frame.4 additional mounting brackets, remove the bearings on the original main mounting bracket, and directly fix the additional mounting bracket on the main mounting with screws, mainly used for the printing of conical products. The additional mounting bracket can be moved up and down by 20 mm.
