Abstract

The utility model relates to a drawing instrument, which comprises a holder and a rolling barrel. The paper can be fixed on the rolling barrel by magnetic strips or stickers, and the rolling barrel is driven by a motor to rotate, which realizes the motion of paper in one direction corresponding to a pen. The drawing instrument not only can draw pictures, but also can engrave pictures when provided with engraving tools. The utility model not only has high repeat accuracy, but also has the advantages of simple structure, easy fabrication, small size and low cost.

Description

Drawing instrument

The utility model relates to a kind of plotter.

At present, commercially available plotter mainly contains two kinds.A kind of is flat bed plotter, and paper is fixed on the flat board, and penholder is by moving on the upper and lower two-layer slideway that is cross of two Electric Machine Control.The shortcoming of this plotter is both direction guide rail mechanism complexity, and the required precision height is made difficulty, and cost is also high.Another kind of plotter is a pinch-roller plotter, and paper is pressed on the guide wheel by contact roller, and an Electric Machine Control guide wheel rotates, and drives paper and moves around, and another driven by motor penholder moves on guide rail.The shortcoming of this plotter is very high to the quality requirement of paper, can not realize fricton-tightly fully when rubbing paper with the hands, and repeatable accuracy is low.

Task of the present utility model provides a kind of plotter, can overcome the deficiency and the low shortcoming of pinch-roller plotter precision of mechanism's complexity of flat bed plotter existence.

Task of the present utility model realizes by following measure: this plotter has clamper and reel, and paper is fixed on the reel.

The utility model has the advantages that:

1, compare with flat bed plotter, because penholder mobile the rotation by reel in one direction replaces, simple in structure, easy to manufacture, volume is little, and cost is low.

2, compare with pinch-roller plotter, do not need contact roller, do not have paper changing of the relative positions problem, the repeatable accuracy height.

Fig. 1 is the structural representation of a kind of embodiment of the utility model.

Fig. 2 is the structural representation of the another kind of embodiment of the utility model.

Fig. 3 is the structural representation of another embodiment of the utility model.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Plotter shown in Figure 1 has comprised a clamper 4, clamper 4 is under the drive of motor, realize moving of a direction, paper is fixed on the reel 8, fixed with Magnetic strip or adhesive sticker, can drive reel 8 by stepper motor or servomotor and rotate, realize that paper is with respect to clamper 4 moving on another direction.

Plotter shown in Figure 2 has guide rail 1, and the

clamper

4 and 6 that can all be in the operating position along 2, two of the walkers that guide rail 1 moves is contained on the walker 2, with movable connection the between the walker 2.The control device that is used to control between the

clamper

4,6 conversion by

magnet

3 and 5 and relative back-moving spring form, magnet and back-moving spring all are contained on the walker 2.When magnet 3 energisings, attract clamper 4, at this moment clamper 4 falls, and begins to draw.During with other one-pen, clamper 4 is set back at need under the effect of its back-moving spring, the frame 2 that is movably walking again makes clamper 6 to drawing position, and magnet 5 energisings attract clamper 6, and clamper 6 falls, and begins to draw.Above-mentioned

magnet

3,5 and relative back-moving spring also can be installed in respectively on clamper 4 and 6.Paper is fixed on the reel 8, is rotated by driven by motor reel 8, realizes that paper is with respect to clamper moving on another direction.Above-mentioned clamper also can be more than two.

Plotter shown in Figure 3 is to be provided with a control stick 7 that parallels with guide rail 1 with Fig. 2 difference more,

magnet

3 and 5 and relative back-moving spring, all be arranged on control stick 7 one ends, be used for controlling the rotation of control stick 7 both directions, thereby realized the conversion between the clamper.

Fig. 2, plotter shown in Figure 3 not only have the above-mentioned advantage of the utility model, but also has following advantage: because of the clamper more than two or two all is in the operating position, at a distance of a very short segment distance,, the change-fountain pen operation just can realize so only needing clamper to move a very short segment distance; There is not complicated change-fountain pen mechanism, the high problem of no change-fountain pen fault rate, simple in structure, reliable operation, cost is low.

Clamper in the utility model can be used to dress pen and draws or be used for adorning icking tool and carry out needle drawing.

Claims

1, a kind of plotter comprises clamper, it is characterized in that, also comprises: reel (8), paper are fixed on the reel (8).

2, plotter according to claim 1 is characterized in that: above-mentioned clamper can be more than two or two, is in the operating position simultaneously.
