[ detailed description ] embodiments
Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the utility model discloses, including the printer storehouse body, its characterized in that: the printer storehouse body is including beating printer head, profiled sheeting, locking bolt, damping telescopic link, base plate, bottom dog and printer storehouse body lower part casing, the fixed bottom dog that is equipped with on the casing of printer storehouse body lower part, the base plate passes through the screw rod and connects in printer storehouse body department, set up the hole that supplies the bottom dog to walk on the base plate, the profiled sheeting is installed to the base plate top, the profiled sheeting passes through the damping telescopic link and sets up in the base plate upper end. The damping telescopic rod comprises a fixing bolt, a spring, a damping telescopic rod inner rod, a damping telescopic rod outer rod and a locking bolt, the damping telescopic rod inner rod is sleeved with the damping telescopic rod outer rod, the spring is sleeved at the upper end of the damping telescopic rod inner rod, one end of the damping telescopic rod inner rod penetrates through the forming plate and is placed above the forming plate, the damping telescopic rod inner rod penetrates through one end of the forming plate and is provided with the fixing bolt, and the fixing bolt and the spring are matched with each other to fix the forming plate through friction force of the fixing bolt and the spring; the locking bolt is arranged at the outer rod of the damping telescopic rod and used for limiting the relative movement of the outer rod of the damping telescopic rod and the inner rod of the damping telescopic rod. The diameter of the bolt hole of the forming plate is slightly larger than that of the fixing bolt, so that corresponding compensation can be realized when the forming plate is inclined and is not parallel to the fixing bolt, the forming plate is not deformed, the inner rod of the damping telescopic rod and the outer rod of the damping telescopic rod can stretch out and draw back in a certain range, and resistance exists, and the resistance is slightly larger than the gravity of the forming plate.
Before the printing platform is leveled, the locking bolt 103 is manually unscrewed anticlockwise, and then an instruction for starting leveling is given to the control panel through a screen or other modes. The printing platform is lowered to the lowest position in the leveling process,
wherein the bottom block 106 can pass through the hole on the base plate 105 to lift the forming plate 102 upward until the damping telescopic rod 104 is extended to the longest state. The XY motor then moves the print head 101 above the first leveling point and the Z-axis motor moves the print platform up slowly to the Z0 position, as shown in fig. 1-3. Since the print head nozzle restricts the movement of the shaping plate 102, the damping telescoping rod 104 is compressed to the appropriate length, which is 0 distance from the nozzle on the print head 101 to the shaping plate. So that the first point is leveled. And then the Z axis descends for a certain distance, the printing head 101 moves to a second leveling point, the Z axis motor drives the printing platform to move upwards to Z0, the leveling of the second point is completed, and the leveling mode of the third point is the same as that of the first and second leveling points. More than three points can determine a plane, and when the distances between the three leveling points and the nozzle are all 0, the forming plate 102 on the printing platform is parallel relative to the XY motion plane. Thus, the entire leveling process is completed, and the locking bolt 103 is manually tightened clockwise.
Fig. 5 is a schematic view of the damping telescopic rod of the present invention, which is only for describing one embodiment of the present invention, and is not limited to this structure. The damping telescopic rod comprises a fixing bolt 201, a spring 202, a damping telescopic rod inner rod 203, a damping telescopic rod outer rod 204 and a locking bolt 205. The fixing bolt 201 and the spring 202 are mutually matched to fix the forming plate 102 through the friction force thereof. The diameter of the bolt hole of the forming plate 102 is slightly larger than that of the fixing bolt 201, so that when the forming plate 102 is inclined and is not parallel to the fixing bolt 201, corresponding compensation can be carried out, and the forming plate 102 is not deformed. The damping telescopic rod inner rod 203 and the damping telescopic rod outer rod 204 can be stretched and retracted within a certain range to form resistance, and the resistance is slightly larger than the gravity of the forming plate. The locking bolt 205 can be used for jacking the damping telescopic rod, so that the length change of the damping telescopic rod is limited.
