Plotter paper holder with automatically feeding central shaft

Abstract

The invention relates to a paper holder with a central shaft driven by a motor to rotate, in particular to an auxiliary paper holder of a plotter. The paper holder comprises a paper-feeding holder, a control holder and a control circuit, wherein a paper roll is mounted on the central shaft of the paper holder, both ends of a central shaft are arranged on pulleys of two pulley seats, a central shaft coupler is spliced with a motor coupler, the central shaft is driven by the motor to rotate, the other end of the central shaft is fixed by a movable positioning seat, two positioning blocks take the action of adjusting the position of the paper roll, paper is conveyed to the plotter for drawing through paper-bearing rods of the control holder, a magnet control rod is mounted between the two paper-bearing rods and used for pulling and putting the paper in a spacing groove of two panels, and two magnetic switches are mounted at one side of either panel and generate control action with the control rod magnet so that the motor is controlled by the circuit to meet the paper feeding requirement of the plotter in drawing. The paper holder controls the motor by adopting the match between the control rod magnet and the magnetic switches and has the advantages of automatic paper roll feeding, load bearing, plotter load lightening, service life prolonging and reduction of paper tube waste.

Description

technical field [0001] The invention relates to an auxiliary paper holder for a plotter. The paper holder is driven by a circuit-controlled motor to serve as a paper holder for automatically following in and out of paper. Background technique [0002] A plotter is a computer that draws a picture and then transmits the data to the plotter through a connecting transmission line, and then the plotter draws the picture on paper. The drawing paper of the plotter is made of paper or roll paper, which can be loaded A detachable shaft is installed behind the paper plotter frame, first remove the shaft, then pass the shaft through the center paper tube hole of the roll paper, and then install the roll paper mounted on the shaft onto the plotter frame together , when plotting, the plotter motor drives the reel shaft to output the paper for plotting, realizing the process of plotting. For the roll paper frame on the traditional plotter, (1) the roll paper frame on the original plotter...

AI Technical Summary

Problems solved by technology

For the roll paper rack on the traditional plotter, (1) the roll paper rack on the original plotter needs to be loaded and unloaded from the rack frequently, which is easy to damage the parts

(2) The roll paper frame on the original plotter is relatively small in terms of load, and only smaller roll paper can be used, resulting in long-term waste of paper rolls and economic losses

(3) The roll paper frame on the original plotter will cause damage to the components of the plotter body on the load, shortening the life of the plotter

(4) The roll paper rack on the original plotter is relatively high, which brings troubles for loading and unloading
