Abstract
The utility model provides a synchronizer of printer die wheel and a varying speed packaging film, wherein the diameter of a rubber-covered roll is equal to the diameter of a die wheel with dies, an angle surge generator is connected with the rubber-covered roll, the angle surge generator is a rotating pattern surge generator, the die is driven by a stepping motor coaxially, the stepping motor is connected with a power source of the stepping motor by power wires, the power source of the stepping motor is connected with the angle surge generator by an output power wire, the rotating angle of a pulse which is outputted by the angle surge generator is equal to an equivalent weight of angle which is rotated by the stepping motor. The structure guarantees that the rubber-covered roll and the die wheel have the same speeds, that is to say, the speed of the packaging film is equal to the speed of the die wheel external diameter with dies, thereby guarantying that clear words are printed by printers, and the flaws of fuzziness, shift words and trailing and the like are avoided.
Description
Affiliated technical field:
The utility model relates to the wrapping machine code printer, especially code printer character wheel linear velocity and speed-variable packing membrane synchronous device.
Background technology:
In the prior art, technique known is the friction-type code printer that still uses in enterprise, this code printer is that the rubber roll that drives packaging film contacts with character wheel, rubber roll drives character wheel and rotates, make the linear velocity of character wheel and the speed synchronization of packaging film, but when the spacing of packaging film typewriting is longer, just character wheel need be lifted the disengaging rubber roll, putting down character wheel again when needs are typewrited contacts with rubber roll, because packaging film is operation continuously, so the character wheel of code printer will constantly lift, put down and put down, lift continuous handling, this just makes rising of code printer character wheel, descending mechanism damages soon, make code printer come out of action ability, this is the existing in prior technology weak point.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, and provide a kind of code printer character wheel linear velocity and speed-variable packing membrane synchronous device technical scheme, this scheme adopts the rubber roll of code printer and the equal diameters of character wheel, rubber roll connects the corner impulse deviser, the character wheel step motor drive of code printer, the rotation of the output control step motor of corner impulse deviser, because the equal diameters of rubber roll and character wheel, rubber roll rotates an angle, the output of corner impulse deviser is just controlled character wheel and is rotated an identical angle, drive the rubber roll rotating speed of packaging film and the synchronization of character wheel like this, just the linear velocity of the running velocity of packaging film and character wheel is synchronous, no matter how the running velocity of packaging film changes, the linear velocity of character wheel and then changes too.
This programme is realized by following technical measures: include on frame and the frame rubber roll that drives packaging film and for the character wheel of character code, the characteristics of this programme are described top roller diameter and the character wheel equal diameters that contains the character code height, corner impulse deviser of the coaxial connection of rubber roll, and character wheel is by the stepping motor coaxial drive; The power supply wire joint is arranged between stepping motor and the driving source for step motor, there is output cable to be connected between driving source for step motor and the corner impulse deviser, the corner of a pulse of described corner impulse deviser output equals the corner that stepping motor rotates an equivalent.The concrete characteristics of this programme also have, and described corner impulse deviser is the rotating grating impulse deviser that adopts.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, top roller diameter and the character wheel equal diameters that contains the character code height, and corner impulse deviser of the coaxial connection of rubber roll, the corner impulse deviser of this device is the rotating grating impulse deviser that adopts.Character wheel then is by the stepping motor coaxial drive.Stepping motor is powered by driving source for step motor, as the driving source for step motor of exporting to of the rotating grating impulse deviser of corner impulse deviser.The corner of a pulse of rotating grating impulse deviser output equals the corner that stepping motor rotates an equivalent.This structure, when not beating coded signal, character wheel does not rotate, and when occurring beating coded signal, character wheel and rubber roll rotate synchronously, and character wheel does not have other action.Owing to do not need moving up and down of character wheel, therefore just there is not the descending mechanism that rises of character wheel, so the code printer long-time running can not occur because of moving of character wheel makes the out-of-action disadvantage of code printer yet, this has just prolonged the work life of code printer.In addition, because the rotating speed of rubber roll and the synchronization of character wheel, just the running velocity of packaging film is synchronous with the linear velocity of character wheel external diameter that contains the character code height, and it is clear that this can guarantee that code printer is beaten the character code of sign indicating number, can not occur that the handwriting is blurred and defectives such as hangover and print position drift.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is frame, and 2 is output cable, and 3 is the corner impulse deviser, and 4 is character wheel, and 5 is rubber roll, and 6 is character code, and 7 is packaging film, and 8 is stepping motor, and 9 is driving source for step motor.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, code printer character wheel linear velocity and speed-variable packing membrane synchronous device, include that frame (1) and frame (1) go up to drive the rubber roll (5) of packaging film (7) and for the character wheel (4) of character code (6), the described rubber roll of this programme (5) diameter and character wheel (4) equal diameters that contains character code (6) height, rubber roll (a 5) corner impulse deviser of coaxial connection (3), the corner impulse deviser (3) of this programme are the rotating grating impulse devisers that adopts.Character wheel (4) is then by stepping motor (8) coaxial drive.Between stepping motor (8) and the driving source for step motor (9) the power supply wire joint is arranged, there is output cable (2) to be connected between driving source for step motor (9) and the corner impulse deviser (3), described rotating grating impulse deviser as corner impulse deviser (3), the corner of a pulse of output equals the corner that stepping motor (8) rotates an equivalent.
