The design can adopt a plurality of elevating screws to come the supporting elevation frame, the problem that the printing plane that causes for the screw mandrel lifting that prevents to exist in the prior art is asynchronous tilts, the quantity of elevating screw should be lacked as far as possible, in order to guarantee stability, this lifter assembly comprises former and later two elevating screws that distribute along the horizontal moving direction of crane with simultaneously.Move because crane also needs to drive the printing flat transverse, so elevating screw has the highest stability along the horizontal moving direction distribution of crane.
It is shaft joint that the utility model adopts the positive drive assembly, shaft joint is made of base and power transmission shaft that elevating screw is installed, the power transmission shaft two ends are provided with the screw thread with the elevating screw lower end engages, in base, be rotatably assorted with elevating screw, when wherein an elevating screw rotates, can drive another root elevating screw by power transmission shaft and rotate synchronously.Or power transmission shaft drives two or two and rotates synchronously with upper screw rod when rotating.
On the basis of above-mentioned lifter, the utility model has designed a kind of flat-panel printer elevating mechanism, comprise abase frame, crane and lifter, lifter is installed between abase frame and the crane, be the elevating screw and the drive motors that is used to drive elevating screw that described lifter comprises two or more supporting elevation framves, be provided with the positive drive assembly that is used for the transmission synchronous operation between the screw mandrel; Also be provided with the nested type slide rail between abase frame and the crane and connect, the nested type slide rail evenly is installed on the outer periphery of lifter.Regulate and stability for the high accuracy that guarantees lifting structure, the utility model increases support and the location that the nested type slide rail is used for whole crane, guarantees that in lifting process crane is in the state parallel with printhead.
Abase frame is connected by equally distributed four nested type slide rails with crane, the lifter assembly comprise be located in the middle of the crane, along former and later two elevating screws that the horizontal moving direction of crane distributes, the positive drive assembly adopts shaft joint equally.Adopt above-mentioned symmetrical structure to make the tool stability of lifting structure of printer, and the member that adopts is minimum, safeguards simple and convenient.
The utility model has following substantive distinguishing features and progress with respect to prior art.
Flat-panel printer lifter that the utility model is designed and lifting structure advantages of simple; member is few; main mating component can be made into integral structure; load-bearing is big, and simple installation has good synchronism; degree of regulation height, uniformity height and stable; guarantee print quality and protected printhead, and be convenient to maintenance management, improve the service life of printer.The design can also adopt automatic control and adjustment and manual adjustments, perhaps the multiple regulative mode of two kinds of combinations.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of flat-panel printer lifting structure as shown in Figure 1 comprises abase frame 1, crane 2 and lifter 3, and lifter 3 is installed between abase frame 1 and the crane 2.In conjunction with Fig. 2 as can be seen, abase frame 1 also further is connected by four nested type slide rails 4 that are evenly distributed on four corners with crane 2, and nested type slide rail 4 evenly is installed on the outer periphery of lifter 3.Nested type slide rail 4 one ends are fixedly mounted on the column of abase frame 1, and crane 2 is installed on the other end of two elevating screws 31 of lifter 3 and nested type slide rail 4.
As seen in Figure 3, lifter 3 comprises the elevating screw 31 of two supporting elevation framves 2 and is used to drive the drive motors 33 of elevating screw 31, and former and later two elevating screws 31 are located in the middle of the crane 2, along crane 2 horizontal moving directions distributions.The shaft joint of lifter 3 is made of base 32 and power transmission shaft 34 that elevating screw 31 is installed, and power transmission shaft 34 two ends are provided with the screw thread with elevating screw 31 lower end engages, is rotatably assorted with elevating screw 31 in base 32.Drive motors 33 drives power transmission shaft 34 and rotates, and power transmission shaft 34 drives two elevating screws 31 and rotates synchronously.
The structure of nested type slide rail 4 is three stage structure as shown in Figure 4, comprises the 3rd slide rail 43 that is used for supporting elevation frame 2, is used for fixing first slide rail 41 and second slide rail 42 that is used to be connected above-mentioned two ends slide rail on abase frame 1.Can slide relatively between first slide rail 41, second slide rail 42 and the 3rd slide rail 43.
In the process of regulating crane 2 rise and fall, by starting 34 rotations of drive motors 33 drive power transmission shafts, because power transmission shaft 34 is a rigidity, its two ends rotational synchronization, turning cylinder 34 can drive two elevating screws 31 and rotate rising or decline synchronously.The thread density that cooperates between turning cylinder 34 and the elevating screw 31 is big more, and density is high more, and then the precision that can regulate is just high more, and this point can be by simple machining realization.The rising of elevating screw 31 or decline can be supported the lifting of whole crane 2, layouts because the directions that two elevating screws 31 laterally move along crane 2 are in line, and be located on the middle position of crane 2, so have very high stability.Crane 2 stable on the other hand from the support of the 4 pairs of cranes 2 of nested type slide rail that are distributed on four corners, in the process of elevating screw 31 supporting elevation framves 2 liftings, nested type slide rail 4 can shorten along with elongation, plays the effect of stable support around crane 2.
