Description

Technical Field

[0001] The utility model belongs to the technical field of money counting machines, and in particular relates to a money counting machine. Background Art

[0002] A money counter is a mechatronic device that automatically counts banknotes, usually with a counterfeit banknote identification function, and is a machine that counts and identifies counterfeit banknotes. The utility model patent with application number 202321521845.6 discloses a channel opening device for a money counter, which has a simple structure. When the back cover is opened, it can automatically drive the lower channel plate to rotate, and when the back cover is closed, it can fix the lower channel plate; it is convenient to open the shell to handle stuck banknotes and clean dust.

[0003] However, the above patent still has the following problems: (1) The rear cover and the lower channel plate are linked by a linkage rod. After multiple openings and closings, the linkage rod and the rear cover and / or the lower channel panel are prone to looseness, so that when the rear cover is opened and closed, the linkage rod cannot move along the predetermined route. The rear cover may get stuck during opening or closing, and the lower connecting plate may not move to the predetermined position as the rear cover opens and closes. Moreover, the linkage of the linkage rod may easily cause uneven force on both sides, affecting the opening and closing of the rear cover. (2) When the rear cover is closed, the rear cover and the housing are fixed by the locking groove and the locking fulcrum of the rear cover. As the number of times the rear cover is opened and closed increases, the fixing effect of the locking groove on the locking fulcrum of the rear cover gradually deteriorates. After the rear cover is opened and closed multiple times, the rear cover may not be closed and may open automatically when the money counting machine is used. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a banknote counting machine whose rear cover can be opened and closed more smoothly than that of the prior art.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a banknote counting machine, including a shell, a transmission channel is provided in the shell, an inspection port is provided on the shell, a back cover is provided on the inspection port, the back cover is rotatably connected to the shell by a rotating shaft, the back cover and the inspection port are relatively fixed by a locking part, the transmission channel includes a lower channel plate, the end of the lower channel plate away from the back cover is rotatably connected to the shell, the end of the lower channel plate facing the back cover is provided with a guide block, the back cover includes a connecting part extending into the interior of the shell, the connecting part is provided with an arc-shaped guide groove for the guide block to be embedded and slide; during the rotation of the back cover relative to the shell, the guide block slides in the guide groove along the extension direction of the guide groove.

[0006] By adopting the above scheme, the lower channel plate can rotate as the rear cover rotates through the cooperation of the guide groove and the guide block. Compared with the prior art, the lower channel plate and the rear cover of this embodiment are directly linked without the need for a linkage pull rod, so that the utility model will not have the rear cover stuck during opening or closing, the lower connecting plate not moving to the predetermined position as the rear cover opens and closes, etc.
