Description
Technical field
The utility model relates to printer, especially relates to a kind of moving blade device for mini-printer cut paper.
Background technology
There are some shortcomings in the existing moving blade device for mini-printer cut paper: 1) can beat during moving knife motion, cut paper position cannot ensure in the same horizontal line, causes fracture sideslip along the line, causes cut paper precision to reduce; 2) cannot realize entirely cutting and hemisection function on same a slice cutting knife, need 2 cutting knife and corresponding 2 sets of transmission mechanism could be realized entirely cutting and hemisection function respectively, cause structure more complicated, cost is higher.
Summary of the invention
The purpose of this utility model is to provide when can prevent moving knife from moving beats, and ensures cut paper position in the same horizontal line; Same cutting knife can realize entirely cut a kind of moving blade device for mini-printer cut paper with hemisection function.
The utility model adopts following technical scheme:
For a moving blade device for mini-printer cut paper, be provided with cap, motor, worm-gears, cutting blade, cutting blade fixed head, moving blade device and installing plate; Motor, worm-gears, cutting blade, cutting blade fixed head and moving blade device are located in cap, and installing plate is located at bottom cap; Cap is connected and composed through securing member by upper cover plate and lower cover, and motor output shaft is connected with worm screw, and worm-wheel shaft central hole is set on projection set by upper cover plate, and cutting blade is buckled on cutting blade fixed head, and lower cover is located on installing plate; Described moving blade device is provided with slide block, moving knife limiting plate and spring, described moving knife fixed head is provided with caulking groove, moving knife limiting plate is pressed on moving knife fixed head, moving knife limiting plate two ends are connected through securing member and lower cover, slide block to be located in moving knife fixed head caulking groove and to be slidably matched with described caulking groove, set by slide block and worm gear, biasing post touches, and both ends of the spring respectively hook is embedded on slide block and moving knife fixed head.
Described both ends of the spring respectively hook is embedded in circular hole set by slip front and in circular hole set by moving knife fixed head.
Set by described slide block and worm gear, biasing post touches, and preferably biasing post side set by slide block side and worm gear touches.
Compared with the prior art, the utility model tool has the following advantages:
Because moving blade device is also provided with moving knife limiting plate and spring, moving knife limiting plate is connected on lower cover through securing member, limiting plate front end and securing member joint face in necessarily press down angle and with cutting knife fixed head interference fit, there is elastic deformation in limiting plate front end, during the motion of cutting knife cut paper, limiting plate front end elastic recoil applies the downforce of normal direction to cutting knife, thus realizes controlling dynamic cutting knife normal direction motion; Worm gear wheel drives biasing post revolution, biasing post and slide block touch is with movable slider level moving, slide block has reaction force to eccentric wheel under spring force effect, power is applied to eccentric wheel and namely tangential force value is applied to worm gear, the back lash of worm gear and worm screw can be reduced, when worm screw is rotated, the worm gear energy very first time makes a response, and can improve the reaction speed of cutting knife; The rotating of structure worm and gear all can take cutting knife motion to; (provide and how to realize controlling set slide block on moving knife fixed head, how controlling the motion of moving knife normal direction.) as can be seen here, the utility model can realize beating when preventing moving knife from moving, ensure cut paper position in the same horizontal line, the accuracy of cut paper distance can be improved; And same cutting knife realizing entirely cut and hemisection function.

Detailed description of the invention
See Fig. 1 ~ 5, the present embodiment is provided with cap (comprising upper cover plate 1 and lower cover 7), motor 2, worm-gears (comprising worm screw 31 and worm gear 32), cutting blade 6, cutting blade fixed head 4, moving blade device and installing plate 8.Motor 2, worm-gears, cutting blade 6, cutting blade fixed head 4 and moving blade device are located in cap, and installing plate 8 is located at bottom cap.Cap is connected and composed through securing member by upper cover plate 1 and lower cover 7, and motor 2 output shaft is connected with worm screw 31, and worm gear 32 axle center hole is set on projection set by upper cover plate 1, and cutting blade 6 is buckled on cutting blade fixed head 4, and lower cover 7 is located on installing plate; Described moving blade device is provided with slide block 11, moving knife limiting plate 9 and spring 10, and described moving knife fixed head 4 is provided with caulking groove, and moving knife limiting plate 9 is pressed on moving knife fixed head 4, described moving knife limiting plate front end 91 and convex closure 41 interference fit set by moving knife fixed head.Moving knife limiting plate 9 two ends are connected through securing member 5 and lower cover 7, slide block 11 to be located in moving knife fixed head 4 caulking groove and to be slidably matched with described caulking groove, slide block 11 touches with biasing post 321 set by worm gear, is with movable slider 11 to slide in moving knife fixed head 4 caulking groove when biasing post 321 rotates set by worm gear.Spring 10 two ends respectively hook are embedded in small sircle hole 110 set by slide block 11 front end and in small sircle hole 410 set by moving knife fixed head 4.At moving knife limiting plate front end 91 elastic recoil, the downforce of normal direction is applied to cutting knife, thus realize controlling dynamic cutting knife normal direction motion.
