Abstract
The invention discloses a printer carriage guiding mechanism which comprises an upper cross beam guide rail and a lower cross beam guide rail parallel to each other; a carriage is connected between the upper and the lower cross beam guide rails; a carriage spring support and a limiting slide block are mounted at the top of the carriage, and respectively positioned on the front side and the rear side of the upper cross beam guide rail; the carriage spring support can enable the upper cross beam guide rail to apply a counterforce on the upper part of the carriage to cause the lower part of the carriage to be clung to the lower cross beam guide rail, so that when the carriage does a reciprocating motion along the upper and the lower cross beam guide rails, the lower part of the carriage is clung to the lower cross beam guide rail, without deviation, and the printing precision and the printing quality are ensured, and meanwhile, the carriage spring support can absorb the vibration of the carriage during the horizontal reciprocating motion. Therefore, the motion of the cutter carriage is more stable.
Description
Technical field
The present invention relates to a kind of equipment of printer, particularly a kind of ink-jet printer word car guiding mechanism.
Background technology
As everyone knows, the word car lower end of ink-jet printer is provided with nozzle, and under the driving of drive unit, make lateral reciprocating displacement along guide rod, nozzle, under the control of program, constantly carries out inkjet printing to printing paper, thus completes print job, when word car moves along guide rail as shift reciprocately, easily because of the impact of vibrations or external force, guide rail can not be close to and move, thus cause printing effect undesirable.
Summary of the invention
In order to solve existing the problems referred to above, the object of the present invention is to provide a kind of structure can ensure simply again the printer carriage guiding mechanism of printing effect.
The present invention is the technical scheme that its technical problem of solution adopts:
A kind of printer carriage guiding mechanism, comprise be parallel to each other upper, sill guide rail, on, word car is connected and installed with between sill guide rail, described word roof is provided with word car spring frame and position limiting slide block, and word car spring frame and position limiting slide block lay respectively at the side, front and back of entablature guide rail, above-mentioned word car spring frame can allow entablature guide rail produce the anti-power of work to word car top, word car bottom is made to be close to sill guide rail, thus order is to word car along upper, when sill guide rail reciprocatingly moves and moves, sill guide rail is close in word car bottom can not there is shift phenomenon, ensure print quality.
Further, the number of described word car spring frame is two, and two word car spring framves are arranged on the left and right sides of end position in word roof respectively, simultaneously, position limiting slide block is arranged on the centre position of two word car spring framves and is arranged on the rear end of word roof, the left and right sides that two above-mentioned word car spring framves are arranged on word roof respectively can make word car held stationary in lateral reciprocating displacement motion length of run, the phenomenon that twists because of word car left and right unbalance stress can not occur, and position limiting slide block can ensure that word car does not depart from entablature guide rail simultaneously.
Further again, the bottom of described word car offer with sill guide rail with the use of guide-track groove, above-mentioned guide-track groove can make the lateral reciprocating displacement motion more freely cunning of word car, can ensure that word car can not come off from upper and lower beam guideway simultaneously.
Further, described word car spring frame is made up of guide runner on fixed support of the fixed support be fixedly connected on word car, eye-splice and the Compress Spring be arranged between fixed support and guide runner, above-mentioned Compress Spring can attract word car to do the vibrations in lateral reciprocating displacement motion process along upper and lower beam guideway, and prevent word car from producing stuck phenomenon because the active force between entablature guide rail is excessive, thus it is more smooth that word car is run.
The invention has the beneficial effects as follows: because word car is mounted on, under be parallel to each other upper, between sill guide rail, and word car top applies elastic force by two word car spring framves to entablature guide rail, thus make the top of entablature guide rail to word car produce a reaction force, this reaction force makes the guide-track groove of word car bottom be close to sill guide rail backward, therefore word car is along upper, sill guide rail is done to remain in shift reciprocately motion process and is close to sill guide rail, thus make the nozzle be mounted on bottom word car that front and back skew or chattering can not occur, thus guarantee print quality, adopt between word car and entablature guide rail simultaneously word car spring frame with the use of, the vibrations in word car traverse motion process can be absorbed, word car and upper can be avoided simultaneously, the stuck phenomenon that active force between sill guide rail is excessive and occur, the lateral reciprocating displacement of word car is moved more smooth.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is overall structure schematic diagram of the present invention;
Fig. 2 is word bassinet structure schematic diagram of the present invention;
Fig. 3 is word car spring shelf structure schematic diagram of the present invention.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, a kind of printer carriage guiding mechanism, the first on a printer good upper and lower upper, lower horizontal direction guiding rail 1,2 be parallel to each other of fixed installation.
Further, process the word car 3 that can be mounted between upper and lower beam guideway 1,2, then, process the guide-track groove 33 be used in combination with lower cross slide way 2 in the bottom of word car 3.
Further again, two symmetrical fixed supports 310 are processed in the left and right sides of word car 3 top middle-end, and then process can the guide runner 311 of eye-splice on fixed support 310, finally Compress Spring 312 is arranged between fixed support 310 and guide runner 311 and forms word car spring frame 31, Compress Spring 312 makes guide runner 311 relatively can make front and back relative disPlacement motion by fixed support 310 under force, the number of above-mentioned word car spring frame 31 is preferably two, certainly selects other numbers also passable.
Further, word car 3 top rear processes the position limiting slide block 32 that is positioned at two spring support 31 centre positions.
Further, word car 3 is arranged between upper and lower beam guideway 1,2, and make sill guide rail 2 rabbet inside the guide-track groove 33 of word car 3, simultaneously two word car spring framves 31 at word car 3 top and position limiting slide block 32 lay respectively at the side, front and back of entablature guide rail 1.
When word car 3 is along upper, sill guide rail 1, 2 do lateral reciprocating displacement motion time, word car spring frame 31 pairs of entablature guide rails 1 at word car 3 top have the elastic force of compression, thus make the top of entablature guide rail 1 pair of word car 3 have an opposition, make the guide-track groove 33 of word car 3 bottom tightly can touch sill guide rail 2, thus when making word car 3 do lateral reciprocating displacement motion, skew or chattering before and after the nozzle be mounted on bottom word car 3 can not occur, ensure printing precision and quality, simultaneously word car spring frame 31 vibrations that word car 3 can also be attracted to do in lateral reciprocating displacement motion process, thus it is more steady to make the lateral reciprocating displacement of word car 3 move, and word car spring frame 31 can also avoid word car 3 with upper, sill guide rail 1, the stuck phenomenon that active force between 2 is excessive and occur.
The foregoing is only preferred embodiments of the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
