Abstract
The utility model relates to the flat-plate printer element field, and aims at overcoming the shortcomings in the prior art and providing a differential elevating mechanism with fast reaction velocity and high working efficiency for the flat-plate printer. The structure of the utility model comprises at least two elevating screws for supporting a printer rack and drive gears used for synchronizing the elevating distance of the screws. The screws are arranged under the printer rack, and are interconnected through the drive gears. The improved structure lies in a high speed driving device and a low speed driving device which drive the screws to elevate. The design is provided with two driving devices with different speed. The driving displacement of the high speed driving device is larger than the driving displacement of the low speed driving device when rotating every lap. When the flat-plate of the printer needs to elevate in a large displacement, the high speed driving device is used to drive the elevating of the printer rack which supports the printing-plate. When the flat-plate of the printer needs to adjust the displacement in high-precision, the low speed driving device is used to drive.

Technical field
The utility model relates to flat-panel printer member field, say so more specifically a kind of can the flexible modulation printing frame flat-panel printer differential elevating mechanism of height.
Technical background
Existing flat-panel printer mainly supports the lifting of printing frame by motor-driven, adopt the mode that drives with speed, for reaching the precision of control, it is very little that motor rotates the distance that every circle printing frame moves, therefore this structure printer reaction speed is slow, and operating efficiency is low.
On the other hand, existing flat-panel printer all adopts the control mode of motor-driven full-automation, manually can't intervene the work of printer, so the work of printer is very inflexible, underaction.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, provides that a kind of reaction speed is fast, the flat-panel printer differential elevating mechanism of high efficiency.
Its further purpose is to increase manual mode, realizes the manual control of the dull and stereotyped lifting of printer.
The utility model is achieved through the following technical solutions its purpose.
A kind of flat-panel printer differential elevating mechanism of the utility model design, comprise at least two elevating screws that are used to support printing frame, the transmission mechanism that is used for synchronous screw mandrel lifting distance, screw mandrel is installed in the printing frame below, interconnects by transmission mechanism, and the structure of its improvement is to be provided with high-speed driving device and the driven at low speed device that drives the screw mandrel lifting.The design is provided with two drive units that speed is different, and the high-speed driving device rotates the drive displacement of every circle greater than the driven at low speed device.When printer is dull and stereotyped when needing big displacement lifting, adopt the high-speed driving device to drive to support and print dull and stereotyped printing frame lifting, when the printer flat board needs high accuracy to regulate displacement, adopt the driven at low speed device to drive.This employing high-speed driving device carries out coarse positioning, and the mode that the driven at low speed device carries out precision positioning improves the locating speed of printer flat board greatly, increases work efficiency.
The type of drive that the design's high-speed driving device or driven at low speed device can adopt manual driving device or Vidacare corp or both to combine makes type of drive versatile and flexible, and humanized to printer control, efficient is higher.
Described high-speed driving device comprises first drive rod and hinge wheel, and first drive rod passes the hinge wheel center of circle and is used to drive hinge wheel; Described driven at low speed device comprises second drive rod and minor sprocket, and second drive rod passes the minor sprocket center of circle and is used to drive minor sprocket; Described hinge wheel and minor sprocket by chain be installed in transmission mechanism on two be connected by movable sprocket.Described first drive rod and second drive rod can adopt manual handle to drive or adopt motor-driven, adopt big or small sprocket diameter difference and the mode of realization differential driving, simple and stable structure, and cost is low.
For improving the stability of elevating mechanism, elevating mechanism comprises three elevating screws, and transmission mechanism is the T font and connects three elevating screws, adopts determine a stability plane at 3, has improved stability of structure and support performance greatly.
The transmission mechanism of T font comprises that an end drives the drive rod of top elevating screw, the drive rod other end by synchronizing wheel and synchronously band drive two elevating screws arranged side by side, describedly be installed on the drive rod by movable sprocket.Synchronously with on can further be provided with the anxiety wheel that is used to adjust synchronous band degree of tightness.
The utility model has two kinds of drives structure that actuating speed is different with precision simultaneously, has improved the speed of the dull and stereotyped location of printer greatly.Adopt manual control mode, improve the flexible of the dull and stereotyped location of printer greatly, thereby further improve printing effect, and make that control is humanized.That realizes is simple in structure, and stability is high, and cost is low, and maintenance and maintenance are all very convenient.With respect to prior art, the design has substantive distinguishing features and progress.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of flat-panel printer differential elevating mechanism as shown in Figure 1, comprise three elevating screws 11,12 and 13, three screw mandrels are triangularly arranged, a screw mandrel 11 is installed on the support 21, two other screw mandrel 12 and 13 is installed on the support 22 side by side, and the top of screw mandrel is used to support the printing frame (not shown).The transmission device that is used between synchronous screw mandrel 11,12 and 13 is the T font, as shown in the figure, comprises drive rod 31 and two synchronizing wheel devices 32 and 33, the synchronizing wheel device by synchronizing wheel and synchronously band constitute.Drive rod 31 1 ends are used to drive screw mandrel 11, the other end by synchronizing wheel device 32 and 33 and two other screw mandrel 12 and 13 carry out synchronously.When drive rod 31 changes, can drive screw mandrel 11 and rise or descend, drive screw mandrel 12 and 13 synchronous runnings simultaneously, thereby realized the adjusting of whole printing frame lifting.
The utility model also is provided with a high-speed driving device and a driven at low speed device, and as shown in the figure, the high-speed driving device comprises that first drive rod 42 and hinge wheel 41, the first drive rods 42 pass hinge wheel 41 centers of circle and are used to drive hinge wheel 41; The driven at low speed device comprises that second drive rod 52 and minor sprocket 51, the second drive rods 52 pass minor sprocket 51 centers of circle and are used to drive minor sprocket 51; Described hinge wheel 41 girths are five times of minor sprocket 51, by chain 61 be installed in drive rod 31 on two be connected by movable sprocket 62.The other end of first, second drive rod 42,52 can pass through handle drives, adopts manual mode to regulate, and perhaps by motor-driven, adopts automatic mode to regulate, or the mode that combines of dual mode.As shown in the figure, when driving 41 rotations of first drive rod, 42 drive hinge wheels, the distance that screw mandrel 11,12 and 13 moves is bigger, and the printing frame lifting is fast, can realize the quick location of printing frame.When driving 51 rotations of second drive rod, 52 drive minor sprockets, the distance that screw mandrel 11,12 and 13 moves is less, and the printing frame lifting is slow, can realize the accurate location of printing frame.
