Description

Technical Field

[0001] The utility model belongs to the technical field of postcard all-in-one machines, in particular to a paper feeding mechanism of the postcard all-in-one machine. Background Art

[0002] The all-in-one postcard machine is an integrated device for printing, stamping and delivery. It usually prints the pattern that tourists want on the postcard as needed, and then uses the stamping device to stamp the postcard with the exclusive stamp of the post office or tourist attraction. After completing the above operations, it is directly delivered to the all-in-one postcard machine. The postal system will mail and transport the delivered postcards.

[0003] The printing process requires the use of a printing device inside the postcard all-in-one machine to print postcards to form customized pattern information for tourists. During the printing process, most existing technologies directly use ordinary color printers as printing devices. This type of printing device directly uses its own paper feeding device as the main paper feeding mechanism, and lacks a paper feeding structure adapted for postcards. Since postcards are relatively thick and have a hard texture, ordinary paper feeding structures are not good at completing paper feeding operations, and paper jams are prone to occur. Utility Model Content

The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0030] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The present invention provides a paper feeding mechanism for a postcard all-in-one machine. Figure 1-Figure 7As shown, the paper feeding mechanism of the postcard all-in-one machine includes a support frame 100, a feed bin 200 and a pressure wheel assembly 300. The pressure wheel assembly 300 is arranged at one end of the feed bin 200. Both ends of the support frame 100 are connected to the inside of the postcard all-in-one machine. The support frame 100 is arranged above the printer 400 provided inside the postcard all-in-one machine.

[0032] The unloading bin 200 includes a bin assembly and a paper pickup guide plate 240 disposed on one side of the bin assembly. The pressure roller assembly 300 extends from the paper pickup guide plate 240 into the bin assembly and applies pressure to the postcards in the bin assembly. When paper feeding is required, the pressure roller assembly 300 rotates to push the postcards into the paper inlet 410 of the printer 400. The printed postcards exit the paper outlet 420 of the printer 400.

[0033] In the present application, the bin body assembly includes an outer plate 210, a pressing plate 220 and a bottom plate 230, and the pressing plate 220 and the bottom plate 230 are connected obliquely. The outer plate 210 is arranged on both sides of the pressing plate 220 and the bottom plate 230. The outer plate 210, the pressing plate 220 and the bottom plate 230 form a receiving slot with an open top structure. The pickup guide plate 240 is arranged on a side of the receiving slot away from the pressing plate 220. A feeding gap for accommodating postcards is provided between the pickup guide plate 240 and the bottom plate 230. The pressure wheel assembly 300 extends from the outer side of the pickup guide plate 240 into the receiving slot and pushes the postcards away from the receiving slot through the feeding gap.

[0034] As a preferred implementation manner in this embodiment, the bottom plate 230 is inclined to the support frame 100, and the bottom of the bottom plate 230 serves as a storage area for the power components of the pressure roller assembly 300; a connecting plate is provided at the end of the bottom plate 230 away from the pressing plate 220, and the connecting plate is vertically connected to the support frame 100, and the pressure roller assembly 300 is in contact and connected with the connection between the bottom plate 230 and the connecting plate;

[0035] The paper pickup guide plate 240 is disposed on a side of the bottom plate 230 away from the pressing plate 220. The feeding gap is located above the connection between the bottom plate 230 and the connecting plate. The paper pickup guide plate 240 is provided with a slot 241. The pressing wheel assembly 300 extends into the interior of the receiving groove through the slot 241.

[0036] The bottom plate 230 is tilted to the horizontal plane. In the initial state, the postcards are tilted and inserted between the pressing plate 220 and the paper guide plate 240 after being stacked. Figure 7As shown, the holding plate 220 and the pickup guide plate 240 provide support for the stacked postcards 500, while the bottom plate 230 provides support for the side edges of the postcards. As the printing progresses, the stacked postcards leave the receiving bin. Under the action of gravity, the postcards in the receiving bin continue to slide along the bottom plate 230 toward the pickup guide plate 240, ensuring that postcards are always present near the feeding gap.

[0037] In this embodiment, a receiving plate 260 is further provided on the outside of the pickup guide plate 240. Postcards emerging from the feed gap first touch the receiving plate 260, and then, under the action of the receiving plate 260, they are diverted and reach the guide plate 250. The guide plate 250 is connected to the paper outlet 420 of the printer 400.

[0038] As a preferred implementation in this embodiment, a paper color sensor bracket 270 is provided above the receiving plate 260. The paper color sensor bracket 270 detects whether there is a postcard in the printer 400 input port. If so, the paper feed motor 340 stops rotating. If not, the paper feed motor 340 continues rotating to transport the next postcard to the receiving plate 260.

[0039] The paper color sensor bracket 270 is a prior art device that mainly helps determine the condition of the printer 400 input port;

[0040] As a preferred embodiment of this embodiment, the pressure roller assembly 300 includes a pressure roller 310, a rotating shaft 320, a transmission wheel group, and a paper feeding motor 340; the paper feeding motor 340 is arranged between the bottom plate 230 and the support frame 100, and the pressure rollers 310 are arranged in two groups on the rotating shaft 320, and the rotating shaft 320 is assembled on the outer plate 210 through a bearing;

[0041] The rotating shaft wheel 331, the guide pulley 332 and the driving pulley 333 are provided. The rotating shaft wheel 331 is provided at one end of the rotating shaft 320, the guide pulley 332 is provided on the bottom plate 230, and the driving pulley 333 is provided on the paper feeding motor 340. The rotating shaft wheel 331, the guide pulley 332 and the driving pulley 333 are connected by a belt; the paper feeding motor 340 generates power to pull the rotating shaft wheel 331 to rotate.

[0042] When paper feeding is required, the paper feeding motor 340 drives the pressing wheel 310 to rotate and push the postcard pressed on the pressing wheel 310 out of the receiving slot; the pressing wheel 310 is a paper pressing wheel with a sawtooth structure, and the sawtooth structure is made of soft rubber material;
