Detailed description of the invention
According to Fig. 1-3, the utility model embodiment is described below, present embodiment is a kind of application example being applicable to the type plate mechanism of impact printer.
As depicted in figs. 1 and 2, type plate mechanism is made up of printer body framework 1, cam 2, camshaft 3, type plate fork 4, type plate guide rail 5, type plate mounting bracket 6, type plate assembly 7, extension spring 8, limiting bracket 9, screw 10, bearing pin 11 etc.The relative two sides of framework 1 are passed at the two ends of camshaft 3, and type plate fork 4 and type plate guide rail 5 are arranged at the both sides of framework 1; Cam 2 be arranged at respectively camshaft 3 two ends and with the end thereof contacts of type plate fork 4; Type plate mounting bracket 6 two ends are provided with tenon, are arranged in the chute of type plate guide rail 5 of two sides respectively; Type plate mounting bracket 6 two ends are contacted with printer body framework 1 by extension spring; Type plate assembly 7 two ends are arranged on type plate mounting bracket 6 by screw 10, and bearing pin 11 is arranged on type plate assembly 7, and are positioned at the chute of limiting bracket 9.
When type plate assembly 7 needs installation, replacing, maintenance, can realize completing fast by screw 10.
During work, when type plate needs to move downward, camshaft 3 starts to rotate, the cam 2 being arranged at camshaft 3 two ends is driven to start to rotate, type plate fork 4 one end contacts with cam 2 and starts to swing, type plate fork 4 other end contacts with type plate mounting bracket 6, drive type plate mounting bracket 6 and the type plate assembly 7 arranged by screw 10 thereon along be arranged at framework 1 both sides type plate guide rail 5 chute in move downward, and be limited to and be arranged on bearing pin 11 on type plate assembly 7 in the chute of limiting bracket 9, do not move left and right, extension spring 8 is simultaneously in extended state.When type plate needs to move upward, camshaft 3 rotates backward, the cam 2 being arranged at camshaft 3 two ends is driven to start to rotate, type plate fork 4 gets back to initial position, type plate mounting bracket 6 and the type plate assembly 7 arranged by screw 10 thereon under the effect of extension spring 8 along be arranged at framework 1 both sides type plate guide rail 5 chute in move upward, extension spring 8 completes reset, and type plate mechanism has once moved up and down.
Because type plate mounting bracket 6 is connected with framework 1 by extension spring 8, so when the thick difference of paper, type plate mounting bracket 6 can realize self-movement with the two ends of the type plate assembly 7 arranged thereon by screw 10, and can not move left and right under the bearing pin 11 be arranged on type plate assembly 7 with the effect of limiting bracket 9, and can rotate around bearing pin 11.
The utility model, by type plate assembly mould blocking being manufactured and designed, reduces design and manufacture cost, is convenient to install, change and maintenance; Type plate assembly two ends can realize self-movement, for the paper printing different-thickness, and the better effects if of printing; Type plate assembly is in motion process all the time under limiting bracket effect, and can not move left and right, printing precision is better.
