Abstract

The utility model discloses a miniature printer machine core with a dustproof cover structure, which comprises a printer lead screw arranged between a left wall plate and a right wall plate, wherein a guide shaft connected on a character impression mechanism is arranged in a spiral groove arranged on the printer lead screw, and a lead screw dustproof cover used for covering the printer lead screw is arranged between the character impression mechanism and the printer lead screw. The product adopts the lead screw dustproof cover for preventing dust and fragments generated by printing paper and color strips in the printing process from entering the lead screw spiral groove, so the dustproof effect is reached, the friction between the lead screw spiral groove and the guide shaft is reduced, the service life of the lead screw is prolonged, and the reliability of the whole body is improved.

Description

A kind of microprinting machine core with dust cover structure
Technical field
The utility model relates to print-out unit, especially the microprinting machine core.
Background technology
With reference to Fig. 1, the word mechanism of car 3 of mini-printer is the axis of guide 31 of printer screw mandrel 2 drive installations on word mechanism of car 3 that is mounted on the left and right wallboard 11,12 at present, make the axis of guide 31 reciprocating in the helicla flute 21 of printer screw mandrel 2, to realize printing function; Its motion mode makes that the 21 pairs of axis of guides of helicla flute on the screw mandrel 2 produce a thrust forward, thereby realizes travelling forward of the axis of guide 31 mainly by screw mandrel 2 rotations.For reducing the friction of the screw mandrel helicla flute 21 and the axis of guide 31, can in screw mandrel helicla flute 21, be added with lubricating oil usually.Because screw mandrel 2 is in the side on the lower side of printhead, in the print procedure of mini-printer, printing paper and colour band produce the dust chip in meeting, and wherein part dust chip drops on the screw mandrel 2, and and then mix with lubricating oil, the increase of this type of impurity will reduce the lubricating quality of lubricating oil, thereby cause the helicla flute 21 of screw mandrel 2 and the frictional force of the axis of guide 31 to increase gradually, wearing and tearing are accelerated, when this situation further develops, it is stuck that word mechanism of car 3 can appear in movement, prints phenomena of the failure such as step-out.
According to statistics, the transmission problem of screw mandrel 2 is major reasons of the fault of the mini-printer that causes.If can improve the runnability of mini-printer screw mandrel 2, can improve the global reliability of mini-printer, also help reducing simultaneously the use cost of product.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of microprinting machine core with dust cover structure, the dust chip that this mechanism can reduce printing paper and colour band generation enters the screw mandrel helicla flute, play dustproof effect, effectively reduce the friction of the screw mandrel helicla flute and the axis of guide, improve the service life and the whole reliability of screw mandrel.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of microprinting machine core with dust cover structure, it comprises the printer screw mandrel that is installed between the left and right wallboard, be provided with the axis of guide that is connected on the word mechanism of car in the helicla flute on the described printer screw mandrel, be provided with the screw mandrel dust cover that is used for the override printer screw mandrel between described word mechanism of car and the printer screw mandrel;
As improvement of the technical scheme, described screw mandrel dust cover includes top board, has the slotted hole of the ccontaining word mechanism of car axis of guide on the top board, and described top board both sides are extended with the forward and backward side plate that is shelved on the printer engine base plate downwards;
As further improvement in the technical proposal, described top board two ends are extended with left and right the sheet that can be connected on the left and right wallboard.
The beneficial effects of the utility model are: the utility model adopts the screw mandrel dust cover to reduce the dust chip that printing paper and colour band produce in print procedure and enters the screw mandrel helicla flute, thereby play dustproof effect, reduce the friction of the screw mandrel helicla flute and the axis of guide, improve the service life and the whole reliability of screw mandrel.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of existing printer engine;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a screw mandrel dust cover structure schematic diagram of the present utility model.
The specific embodiment
With reference to Fig. 2, a kind of microprinting machine core with dust cover structure, it comprises the printer screw mandrel 2 that is installed between the left and right wallboard 11,12, be provided with the axis of guide 31 that is connected on the word mechanism of car 3 in the helicla flute 21 on the described printer screw mandrel 2, be provided with the screw mandrel dust cover 4 that is used for override printer screw mandrel 2 between described word mechanism of car 3 and the printer screw mandrel 2, the use of screw mandrel dust cover 4, effectively guaranteed in the microprinting machine core print procedure, reduce the dust chip and enter helicla flute 21, effectively reduced dust sticking and gather at helicla flute 21.
With reference to Fig. 3; the screw mandrel dust cover 4 that this product uses includes top board 41; have the slotted hole 411 of the ccontaining word mechanism of car axis of guide 31 on the top board 41; described top board 41 both sides be extended with downwards be shelved on the printer engine base plate 5 before; back side panel 42; for screw mandrel dust cover 4 is fixed on the printer engine; described top board 41 two ends are extended with can be bonding or be bolted to a left side; right wallboard 11; left side on 12; a right sheet 412; 413; certainly; according to actual needs; screw mandrel dust cover 4 also is not limited to above-mentioned technical scheme; can adopt other common technology types; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model in a word.
The utility model adopts screw mandrel dust cover 4 to reduce the dust chip that printing paper and colour band produce in print procedure and enters screw mandrel helicla flute 21, thereby play dustproof effect, reduce the friction of the screw mandrel helicla flute 21 and the axis of guide 31, improve the service life and the whole reliability of screw mandrel 2.
