Description

Technical Field

[0001] The utility model relates to the field of numbering machines, in particular to an automatic numbering machine which can be rotated to quickly return to zero and automatically sink and hide. Background Art

[0002] The automatic numbering machine is the most commonly used manual code printing operation tool in document and paper coding. At present, the basic principle of almost all automatic numbering machines on the market is to press the handle to make the movable claw link to drive the code wheel to advance. Each press advances one position, or presses down several times to advance one position. At present, the reset of the code wheel after the automatic numbering machine is used can only rely on manual hands or tools such as dial sticks to dial each code wheel in turn. Due to the complex structure of the automatic numbering machine, the operation space for dialing the code wheel is small, it takes a long time and is easy to operate incorrectly. For example, a certain document starts from 00001 and ends at 09988 pages. After we use it, we need to use a tool to rotate the 8 in the ones position back to 0, the 8 in the tens position back to 0, the 9 in the hundreds position back to 0, and the 9 in the thousands position back to 0. Similarly, it takes a lot of time to dial all the code wheels back to the initial 0 position after each use.

In this embodiment, five sunken digit wheels 21 are schematically selected. According to the use requirements, other numbers of sunken digit wheels 21 may also be used.

[0025] like Figure 4 As shown, a slot 131 is axially arranged on the outer circumference of the rotating shaft 13, and a one-way rotating ring 20 corresponding to the sunken character wheel 21 is mounted on the rotating shaft 13, and the one-way rotating ring 20 has a slotted platform portion that is stuck in the slot 131. The one-way rotating ring 20 has an arc groove 201 on the upper part, and the one-way rotating ring 20 has an outer circumferential surface, and the arc groove 201 is depressed downward on the outer circumferential surface, and the sunken character wheel 21 has a long hole 210, and the long hole 210 includes a straight channel and two semicircular channels connected at both ends of the straight channel, and the semicircular channels are adapted to the outer circumferential surface contour of the rotating shaft 13. The upward direction of the long hole 210 is the same as the notch direction of the arc groove 201.

[0026] The sunken character wheel 21 is provided with a connecting column a212, and a positioning claw a19 whose end can abut against the arc groove 201 is rotatably provided on the sunken character wheel 21. When the end of the positioning claw a19 abuts against the arc groove 201, the sunken character wheel 21 slides upward on the rotating shaft 13 through the long strip hole 210, that is, it sinks upward. The connecting column a212 is connected to a special-shaped spring a22, which is an L-shaped strip spring. The outer end of the special-shaped spring a22 abuts against the side of the positioning claw a19 to ensure that the end of the positioning claw a19 abuts against the one-way rotating ring 20.

[0027] The sunken character wheel 21 has a mounting groove a211, and the positioning claw a19, the one-way rotating ring 20, the connecting column a212 and the special-shaped spring a22 are all located inside the mounting groove a211, making the structure compact and occupying little space.
