Abstract

The invention relates to a printer. The printer comprises a base on which a guide rail and a tray longitudinally moving relative to the base along the guide rail are arranged, the upside position of the tray is provided with a printing unit, and the base is provided with a dismountable conversion rack on which at least a pair of parallel roller wheels or rollers rotated by the rolling friction force generated by the surface of the tray when the tray longitudinally moves are arranged. When the conversion rack is not mounted, placing an object on the tray and printing on the plane can be realized; when the conversion rack is mounted, a columnar surface object is placed on the roller wheels or the rollers of the conversion rack, and the friction force generated by moving tray and the roller wheels or the rollers drives the roller wheels or the rollers to rotate, and further drives the columnar printed object to rotate so as to print pictures and texts on the columnar surface line by line. Compared with the prior art, no matter printing on the plane or the columnar surface, the problem that a component for placing the printed object runs unstably does not appear, so that the printer can control the printing quality better.

Summary of the invention

The purpose of this invention is to provide a kind of not only can the printing but also can be at the printer of face of cylinder printing on the plane.

For achieving the above object, printer of the present invention comprises base, the pallet that guide rail is set on the base and vertically moves along the relative base of guide rail, in the pallet top position print unit is set also on the described base, also be provided with on the described base and removably change frame, be provided with on the described conversion frame that at least one pair of is parallel to each other, can be when pallet vertically moves produce with tray surface that force of rolling friction drives and with respect to the roller or the roller of conversion frame rotation.

Be provided for regulating the screw feed screw apparatus of roller or roller spacing on the above-mentioned described conversion frame, the wheel shaft of described roller or roller is arranged on the screw; The end of described leading screw is provided with adjusting knob; Described base is provided with the strip hole that vertical direction extends, and the limited post that stretch out described conversion frame both sides drops in the strip hole; Described roller or roller are dismountable being arranged on the described conversion frame; Described print unit base is relatively regulated at vertical direction.

The present invention removably changes frame owing to being provided with on base, therefore except can being implemented in, the state that the conversion frame is not installed places object on the pallet printing on its plane, can also be under the state that the conversion frame is installed, on the roller of changing frame or roller, place face of cylinder object, the dependence pallet moves the frictional force drives roller and the roller that produce with roller or roller and rotates, and further driven the face of cylinder and be printed the rotation of object, thereby make the shower nozzle of print unit on the face of cylinder of face of cylinder object, print picture and text line by line.

Compared with prior art, when printing in the plane, because pallet vertically moves along guide rail, it is stable moving, the problem that wanders off of having avoided the prior art plane to print; Again owing to the conversion frame is mounted on the base, roller or roller are mounted on the conversion frame, therefore the operation of roller also is stable, no matter be to print on the plane or print in a word on the face of cylinder, the problem of the parts fluctuation of service of printing objects can not occur placing, improve control performance print quality.

Fig. 2 is the structural representation that Fig. 1 removes candle and print unit;

Fig. 3 is a conversion frame part-structure schematic diagram of the present invention.

The specific embodiment

As shown in Figure 1, printer of the present invention comprises base 1, guide rail 2 is set on the base 1, pallet 3 can vertically move at the driving lower edge of stepper motor (not shown) guide rail 2 relative bases 1, print unit 4 is set above pallet 2 on the base 1, have the printhead 5 that can move back and forth at left and right directions on the print unit 4, also be provided with on the base 1 and removably change frame 6, on the conversion frame 6 left and right sides is set and is symmetrical arranged two pair rollers 7 that are parallel to each other, roller 7 can be when pallet 3 vertically moves and pallet 3 surfaces produce force of rolling frictions and rotate with respect to conversion frame 6 under driving, the wheel shaft of roller 7 by the bearing (not shown) with change frame 6 and connect; Print unit 4 base 1 is relatively regulated at vertical direction.

As shown in Figure 2, base 1 is provided with vertically the strip hole 10 that extends, and the limited post 11 that stretch out conversion frame 6 both sides drops in the strip hole 10, in order to the horizontal motion of restriction conversion frame 6; Roller 7 dismountable being arranged on the conversion frame 6; When this structure made replaceable greater or lesser roller 7, the height of the relative pallet 3 of conversion frame 6 varied in size with roller 7 and different, and 10 of strip holes have guaranteed that it is freely that conversion frame 6 is highly regulated.

As shown in Figure 3, be provided for regulating the screw feed screw apparatus of roller 7 distance between axles on the conversion frame 6, the wheel shaft of roller is arranged on the screw 12; The end of leading screw 13 is provided with adjusting knob 14; When needing to regulate the distance between axles of roller 7, can get final product like this by screwing knob 14 with receipts.

In general, print unit 4 all is arranged to relatively base and is regulated at vertical direction.

During actual the use, printer of the present invention has two kinds of user modes, a kind of is that the conversion frame is not installed in the state on the printer, can place the object that has the plane this moment on pallet, candle as the quadrangular shape, start printer, then pallet can drive candle stepping in a longitudinal direction, printhead on the print unit moves back and forth simultaneously, on a plane of candle, print picture and text line by line, for adapting to the object that is printed of different sizes, it is adjustable on vertical height that print unit is set up with respect to base, can transfer to optimum distance so that its printhead specifically is printed body surface, obtains optimal printing quality and picture effect, this is the content of prior art flat-panel printer technology, repeats no more; Another kind of state is, the conversion frame is installed on the printer base, at this moment, can at least two pair rollers or a pair of roller, place columniform object, columned as shown in Figure 1 candle 8, start printer, then vertical stepping of pallet move and roller or roller between the frictional force drives roller that produces or roller stepping rotate, the cylindric candle stepping that the rotation of roller or roller drives again on it is rotated, with its while, the printhead of print unit moves back and forth, line by line on the top, the face of cylinder of cylindrical candle or print picture and text fully.

When the diameter of candle is excessive or too small, can realize printing by one of two kinds of ways or their combination, a kind of is adjusting knob 14, changes the distance between axles between the roller 7; Change the roller 7 of greater or lesser diameter besides.

Pallet normally forms guiding sliding connection relation with base, and specifically, pallet is normally under the driving of printer stepper motor, along the respective slide slots longitudinal sliding motion on the base.

Need not speak more, printer will link to control with computer usually, and computer can be external PC, also can be built-in embedded-type ARM machine.Roller of the present invention and roller do not have essential distinction, and constantly extension then is called described roller to the roller of both sides shown in Figure 1 until becoming one to the centre.
