[0001] The present invention relates to the technical field of printing and stamping, and in particular to a channel switching device and a batch printing and forgery-proof stamping integrated machine. Background Art

[0002] In the traditional sense, printers, stamping machines, and scanners are all independent devices. When a user needs to scan and authenticate a document that has been signed and stamped by a customer and then stamp it, it is usually necessary to manually place the document that has been signed and stamped by the customer into the scanner for scanning and authentication, and then select the document pages that need to be stamped from the scanned and authenticated document and manually send them to the stamping machine to stamp the corresponding document pages. Later, in order to save floor space, reduce costs, and improve work efficiency, printers, stamping machines, and scanners are combined in a single housing to form a batch printing and forgery-proof stamping integrated machine that integrates printing, authentication, and stamping functions. However, in the existing batch printing and forgery-proof stamping integrated machines, the documents output by the printer and the scanner can only enter the stamping machine and then be transmitted out from the document output port communicated with the paper outlet of the stamping machine. For documents that do not require authentication and stamping, they still need to be printed separately by another printer, and the printer in the batch printing and forgery-proof stamping integrated machine cannot be effectively and fully utilized.

[0044] As Figure 1 and Figure 2 As shown, the channel switching device 100 according to the embodiment of the present invention includes an upper bracket 110, a lower bracket 120, and a support plate 130. The upper bracket 110 and the lower bracket 120 are in an L-shaped structure. The lower bracket 120 is sleeved outside the upper bracket 110. The left and right ends of the upper bracket 110 and the lower bracket 120 along their length directions are both supported by the vertically arranged support plate 130. The gap between the upper bracket 110 and the lower bracket 120 forms a channel for paper transmission. An oscillating member 111 that can swing relative to the upper bracket 110 is provided on the upper part of the upper bracket 110 along its length direction. One end of the main shaft of the oscillating member 111 is connected to an oscillating motor 113. The oscillating motor 113 drives the oscillating member 111 to swing, so that the oscillating member 111 connects different paper feeding channels to perform different channel switching.

[0045] As Figure 1 and Figure 2 As shown, in some specific embodiments of the present invention, upper support columns 118 are symmetrically arranged on the outer sides of both ends of the upper bracket 110 along its length direction. A lower support shaft 124 is provided on the lower bracket 120 along its length direction. The lower support shaft 124 is arranged parallel to and below the upper support column 118. The upper end of the support plate 130 is clamped with the upper support column 118, and the lower end is clamped with the lower support shaft 124.

A detection plate 119 is fixedly connected to the main shaft of the swinging member 111. The detection plate 119 swings together with the main shaft of the swinging member 111. The detection plate 119 is arranged outside the upper bracket 110. A monitoring device 150 for monitoring the swinging angle of the detection plate 119 is arranged on the upper bracket 110. In this embodiment, the monitoring device 150 is a commutation sensor. The swinging angle of the detection plate 119 is monitored through the commutation sensor, that is, the swinging angle of the swinging member 111 is detected, so as to determine the channel entrance connected by the swinging member 111.

[0047] Further, in this embodiment, the swinging member 111 is a plurality of grid bars arranged in parallel and evenly distributed on the main shaft of the swinging member 111. The plurality of grid bars are fixedly connected to the main shaft of the swinging member 111 by welding or interference connection. The number of grid bars and the distance between every two grid bars can be adjusted according to the width of the object entering the channel switching device 100 to adapt to objects of various width specifications. In other embodiments, the swinging member 111 can also be a swinging plate. Connecting columns are arranged on both sides of the swinging plate along the length direction of the upper bracket 110. One end of the connecting column on one side of the swinging plate passes through the upper bracket 110 and is connected to the rotating shaft of the swinging motor 113 through a first coupling 112.

The plurality of protrusions 114 are arranged along the length direction of the upper bracket 110 and towards the main shaft of the swinging member 111. The distance between every two protrusions 114 matches the width of the grid bar. During the swinging process of the grid bar, one end of it passes through between the protrusions 114 to avoid interference between the grid bar and the upper bracket 110 and affect the swinging angle of the grid bar. In the embodiment where the swinging member 111 is a swinging plate, the distance between the two protrusions 114 matches the length of the swinging plate.
