Problems solved by technology

At present, two methods are commonly used: 1. Use two sets of power drive devices to drive the continuous medium and single-sheet medium switching mechanism and the paper guide wheel lifting and pressure adjustment mechanism respectively. This method increases the cost due to the addition of a power source; 2. , Use the gear and rack mechanism to link the continuous medium and the single-sheet medium switching mechanism and the paper guide wheel lifting and pressure adjustment mechanism. This method requires a relatively large space

Embodiment Construction

[0014] As shown in Figure 1, it is a structural representation of the present invention. A device capable of automatically switching continuous media and single-sheet media in a printer, comprising a power drive device 1 and a continuous media tractor 15, the continuous medium tractor 15 has a tractor driving gear 14, wherein the tractor The driving gear 14 is a square shaft gear. In this technical solution, the power drive device 1 includes a motor 2, a reduction drive gear 3, a reduction gear 4, and an intermediate gear 5. The gear of the motor 2 meshes with the reduction drive gear 3, and the reduction drive gear 3 and the reduction gear The gear 4 is coaxially interlocked, the reduction gear 4 meshes with the intermediate gear 5, the intermediate gear 5 meshes with a switching driving gear 6, and the switching driving gear 6 is coaxially interlocking with a switching tooth-missing gear 7. A part of the circumference of the switching toothless gear 7 is provided with teeth...

Abstract

The invention discloses an apparatus which can automatically switch a continuous medium and a single page medium of a printer, comprising a power-driven device and a paper tractor of continuous medium. The utility model is characterized in that the central gear of the power-driven device meshes with a switching driving gear which moves together with a switching edentulous gear on the same shaft, partial circum of the switching edentulous gear is provided with tooth and meshes with the tooth of a switching arm changing gear, and clutches are installed on the switching arm changing gear; a status switching driving gear meshes with a rear friction roll gear and moves together with a status switching gear on the same shaft; the status switching gear meshes with driven gears of the paper tractor of the continuous medium; the switching arm gear is provided with a resetting spring. As the invention adopts the structure, the invention is characterized by low manufacturing cost and small coverage space, which can realize the automatic switch between the continuous medium and the single page medium of the printer.

Description

technical field [0001] The invention relates to a switching device capable of switching continuous media and single-sheet media of a printer, more specifically, relates to a device capable of automatically switching continuous media and single-sheet media of a printer. Background technique [0002] Most of the current dot matrix printers switch between continuous media and single-sheet media using manual switching. However, as customers have higher and higher requirements for dot matrix printers, different media must be processed in different states, even the same media must be switched to different states in different processes. This will inevitably require the switch between the continuous medium and the single-sheet medium of the dot matrix printer to develop in the direction of automation. This involves how to link the continuous medium and single-sheet medium switching mechanism of the dot matrix printer with the lifting mechanism of the paper guide wheel and the press...
