Detailed Description

The structure of the present invention will be further described by way of examples with reference to the accompanying drawings. It is to be understood that this embodiment is illustrative and not restrictive.

A plotter suitable for high humidity environment, please refer to fig. 1-5, which is characterized in that: comprises a plotter body, a dehumidification base and a humidity control system;

the plotter body includes body shell 1, installs printing function module and drawing control system in the body shell. The body shell is generally formed by connecting a plurality of shell pieces, and sealing strips are adopted at the connecting parts to realize a full-sealing design. The bottom end of the body shell is an open end. A drawer stretching type roll paper storage bin 2 is arranged on one side of the body shell, roll paper is installed conveniently after the roll paper storage bin is opened, and the roll paper storage bin can be attached to the body shell after the roll paper storage bin is closed to form a sealing effect. A paper outlet is arranged on the side of the body shell, the paper outlet is arranged above the roll paper storage bin, and a paper outlet cover plate 3 which can be opened and closed is arranged at the position of the paper outlet. The paper outlet cover is connected with the body shell through a hinge, and the motor of the paper outlet cover controls the opening and closing of the paper outlet cover plate. The specific control structure refers to the switch control structure of the vent cover. When the plotter worked, exit cover opened, guaranteed that the paper of printing the completion can be smooth send out. Sealing rubber strips are arranged between the edges of the four edges of the paper outlet cover plate and the matching parts of the paper outlet, so that the paper outlet cover plate is in sealing contact with the body shell in a closed state.

The dehumidification base 4 comprises a base shell 4.1, the upper end of the base shell is an open end, a longitudinal clapboard is arranged in the base shell and divides the inner cavity of the base shell into an outer air dehumidification piece installation cavity and an inner air dehumidification piece installation cavity. The drying filter element 4.4 is arranged in the outer air dehumidifying element mounting cavity, the plurality of fan sets 4.3 are longitudinally arranged at the upper end of the drying filter element, an air inlet is arranged on the wall of the base shell corresponding to the outer air dehumidifying element mounting cavity, the air inlet is aligned with the side surface of the drying filter element, and an openable vent cover 4.2 is arranged at the position of the air inlet. The vent cover is connected to the base shell through a hinge and drives the motor 4.6 to control the switch through the vent cover. Specifically, motor gear 4.7 is installed on the ventilation port cover driving motor, the motor gear is meshed with gear wheel 4.8, one end of connecting rod 4.13 is connected with first rotating shaft 4.14 on the gear wheel, the other end is connected with second rotating shaft 4.12 on the ventilation port cover, and the ventilation port cover is connected on the base shell through hinge 4.10 and can rotate around the hinge. When the motor drives the bull gear to rotate rightwards, the connecting rod pushes the vent cover to be opened, when the motor drives the bull gear to rotate leftwards, the connecting rod pulls the vent cover to be closed, the vent cover is provided with a sensor contact 4.11, the sensor is fixed inside the base shell to be 4.9, and the switch state of the door can be detected through the sensor. Sealing rubber strips are arranged between the four edges of the vent cover and the matching part of the air inlet, so that the vent cover is in sealing contact with the body shell in a closed state. A semiconductor condensation dehumidifier 4.5 is arranged in the inner air dehumidifying part mounting cavity, and a drain pipe of the semiconductor condensation dehumidifier extends out through a pipe hole arranged on the base shell. The semiconductor condensate dehumidifier is not limited to the two shown in the drawings.

The dehumidification pedestal mounting is in the below of plotter body, butt joint and be provided with the sealing strip about base shell and the body shell constitutes the plotter shell, the inside airtight space that forms of plotter shell.

The air inlet on the dehumidification base is arranged on one side opposite to the paper outlet of the plotter body.

Above-mentioned fan assembly is used for to the inside air that supplies with of plotter, when needs are to supply dry air in the plotter, control flap lid motor opens the flap, and drive fan assembly is rotatory, and the air gets into by the air intake, and inside the dry back entering plotter of drying filter core dehumidification, the inside malleation that forms of plotter. Above-mentioned semiconductor condensation dehumidifier is used for keeping the inside humidity of plotter stable, prevents that humidity is too high, and the water that the condensation formed passes through outside the drain pipe discharge plotter.

The humidity control system is integrated on a plate of the plotting control system, is used for keeping the humidity in the plotter stable, and is provided with an external humidity sensor and an internal humidity sensor (not shown in the attached drawing), wherein the internal humidity sensor is used for detecting the air humidity in the plotter when the plotter is in standby and controlling the working state of the semiconductor condensation dehumidifier through the humidity control system; the external humidity sensor is used for detecting the air humidity outside the plotter when the plotter works, and controlling the switch device of the vent cover and the working state of the fan set through the humidity control system. The humidity control system counts the service life of the dry filter element by recording the environment humidity and the dehumidification working time, ensures the timely replacement of the filter element and ensures the dehumidification effect. The specific process is as follows:

when the plotter standby state, when detecting the inside humidity transducer humidity of plotter when too high, humidity control system starts semiconductor condensation dehumidifier, reduces the inside humidity of plotter.

When the plotter is ready to print, the humidity control system reads the external humidity sensor of the plotter, and when the external humidity is not higher than RH 60%, the paper outlet cover is opened, and the plotter normally enters a printing state; when outside humidity is higher than RH 60%, start the dehumidification procedure, open vent flap earlier, start fan group, treat inside dry back air admission plotter for the inside air of plotter forms the positive pressure for the outside, open out the paper flap this moment, the plotter gets into normal printing flow, keep inside the plotter positive pressure prevent that humid air from getting into the plotter, treat to print the end and close out the paper flap earlier, close fan group and vent flap in order again, get into standby state again.

Although the embodiments of the present invention and the accompanying drawings are disclosed for illustrative purposes, those skilled in the art will appreciate that: various substitutions, changes and modifications are possible without departing from the spirit of the invention and the scope of the appended claims, and therefore the scope of the invention is not limited to the disclosure of the embodiments and the accompanying drawings.
