Abstract
The utility model is applied to the technical field of printing supplies and provides a printer control device. The printer control device comprises a roller shaft and a printing roller rotating around the roller shaft. A plurality of air suction holes are arranged on the roller wall of the printing roller, two ends of the air suction holes are respectively provided with air channels communicated with the peripheral surface of the printing roller and the inner cavity surface of the printing roller, plungers sliding along the axis of the air suction holes are respectively arranged in the air suction holes, and springs for pushing the plungers to the peripheral side of the printing roller are arranged between the plungers and the roller wall of the printing roller. According to the printer control device, a function of automatic paper absorption is achieved when paper is arranged on the surface of the roller in a vacuum absorption area through the plungers in the air suction holes, and a function of automatically sealing the air holes without paper is achieved, absorption control of paper of different sizes is achieved, printing faults caused by air leakage of the air suction holes is removed, and normal work of a printer is ensured.
Description
Technical field
The utility model relates to the printing consumables technical field, relates in particular to a kind of printer control device.
Background technology
The paper of printing is admitted to type drum, and shower nozzle carries out inkjet printing on mobile paper, and the paper after having printed is sent to paper arrangement platform again.But, the break-make that the suction hole of the setting above the type drum can not single or single control air, when antiquarian diminished, the suction hole on the type drum that can not be covered by paper can leak gas, and causes occurring print fault, the printer cisco unity malfunction.
The utility model content
The purpose of this utility model is to provide a kind of printer control device, and the printer that the prior art that is intended to solve provides makes suction hole produce gas leakage owing to antiquarian changes, cause occurring print fault, the problem of printer cisco unity malfunction.
The utility model is to realize like this, a kind of printer control device, printer control device comprises drum shaft and the type drum that rotates around described drum shaft, be provided with several suction holes in the described type drum barrel, described suction hole two ends are respectively equipped with the air flue that is communicated with type drum outer surface and type drum surface of internal cavity, be respectively equipped with the plunger that slides along the suction hole axis in the described suction hole, be provided with the spring of described plunger being pushed to the type drum outer circumferential side between described plunger and the described type drum barrel.
The printer control device that the utility model provides is by the plunger in the suction hole, automatic absorbing paper when realization has paper at vacuum suction district cylinder surface, the function of self-closed pore during without paper, reach the absorption and control to the different size paper, got rid of because the print fault that suction hole gas leakage causes guarantees the normal operation of printer.
Description of drawings
Fig. 1 is the structural representation of the printer control device that provides of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Fig. 1 shows the structural representation of the printer control device that the utility model provides, and for convenience of explanation, has only provided the part relevant with the utility model among the figure.
The concrete structure of printer control device is as described below:
Type drum 1 is around drum shaft 2 rotations, and drum shaft 2 is provided with the air intake passage that is communicated with type drum 1 inner chamber, makes the interior negative-pressure vacuum that forms of cavity of type drum 1.
Be arranged with uniformly several suction holes 3 on the barrel of type drum 1, described suction hole 3 two ends are respectively equipped with the air flue that is communicated with type drum outer surface and type drum surface of internal cavity, be respectively equipped with the plunger 4 that slides along suction hole 3 axis in the described suction hole 3, described plunger 4 is provided with the passage that is communicated with plunger 4 two ends, and described passage two-port departs from described air flue and is positioned at opening on described suction hole 3 inner surfaces, is provided with the spring of described plunger 4 being pushed to type drum 1 outer circumferential side between described plunger 4 and type drum 1 barrel.
When suction hole 3 is not blocked by paper, atmospheric pressure can overcome the elastic force of spring 5 and frictional force, the centrifugal force of plunger 4, plunger 4 is depressed, plunger 4 seals the gas port that suction hole 3 leads to type drum 1 inner chamber, the passageway shuts off of type drum 1 inner chamber being led to type drum 1 outer surface, automatically dying when realizing without paper; When suction hole 3 was blocked by paper, the air in the cavity between plunger 4 and the paper was sucked away by passage, all forms vacuum in the both sides cavity of plunger 4, and paper just is adsorbed on type drum 1 outer surface firmly, thereby automatically ventilates when having realized paper.
The printer control device that the utility model provides is by the plunger in the suction hole, automatic absorbing paper when realization has paper at vacuum suction district cylinder surface, the function of self-closed pore during without paper, reach the absorption and control to the different size paper, got rid of because the print fault that suction hole gas leakage causes guarantees the normal operation of printer.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
