Description

Technical Field

[0001] This utility model relates to the field of numbering machines, and in particular to an automatic numbering machine that can be rotated to zero and hidden. Background Technology

[0002] Automatic numbering machines are one of the most commonly used manual printing tools for document and paper coding. Almost all automatic numbering machines on the market operate on the principle of pressing down on a handle to move a pawl, which in turn moves the number wheels. Each press advances one position, or several presses advance one position. Currently, after using an automatic numbering machine, resetting the number wheels relies entirely on manual operation using a hand or a dial tool to rotate each wheel sequentially. Due to the complex structure of automatic numbering machines and the limited space for manipulating the number wheels, this process is time-consuming and prone to errors. For example, if a document starts at 0001 and ends at page 6666, after using the numbering machine, it's necessary to use a tool to rotate the units digit 6 back to 0, the tens digit 6 back to 0, the hundreds digit 6 back to 0, and so on. Each time, this requires a significant amount of time to rotate all the number wheels back to their initial 0 position, making the operation quite cumbersome.

[0003] Chinese Patent Publication No. CN209971927U discloses a hand-typed number printer with a reset function and a number wheel sinking function. The hand-typed number printer includes a printer body, a number wheel, and a main shaft. A protrusion is movably provided on the main shaft in the radial direction. Using this technical solution, the number wheel can be reset by rotating the main shaft.

[0004] However, the above technical solution has the following drawbacks: the protruding part is not easy to assemble between the spring hole and the number wheel, which affects the assembly efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic numbering machine that can be rotated to zero and hidden. This facilitates the assembly of the unit digit wheel, the recessable digit wheel, the positioning claw, and the one-way rotating ring. It can zero multiple number wheels by rotating the shaft, making the operation simple and convenient for the recessable digit wheel to be lowered.

[0006] The technical solution of this utility model is an automatic numbering machine that can be rotated to zero and hidden, including a numbering machine body, a rotating shaft mounted on the numbering machine body, and multiple number wheels equidistantly mounted on the rotating shaft; the multiple number wheels include a unit digit wheel for printing the unit digit and other retractable number wheels for printing other digits; a groove is provided on the outer circumference of the rotating shaft, and a one-way rotating ring corresponding to each of the multiple number wheels is fitted on the rotating shaft; the retractable number wheels have a mounting groove on one side of their axial direction. The number wheel has a through-hole along the axial direction. The inner side of the through-hole has an inwardly protruding insertion platform that fits into the slot. A V-shaped positioning claw is rotatably mounted on the number wheel. When the insertion platform is inserted into the slot, one end of the positioning claw is located on the outer circumference of the one-way rotating ring, and the corresponding number wheel is recessed upward. When the insertion platform is removed from the slot, one end of the positioning claw abuts against the outer circumference of the one-way rotating ring, and the other end abuts against the inner circumference of the mounting groove. The corresponding number wheel is at the same height as the unit number wheel.

[0007] Preferably, the positioning claw is an elastic element, and the outer circumferential surface of the one-way rotating ring has a locking tooth for pushing one end of the inner side of the positioning claw.

[0008] Preferably, the strip hole includes a straight channel and two semicircular channels respectively connected to both ends of the straight channel. The semicircular channels are adapted to the circumferential surface contour of the rotating shaft, and the insertion platform is located inside one of the semicircular channels.

[0009] Preferably, the numbering machine body includes a latch and a latch spring that elastically presses against the outside of the latch and the outside of multiple number wheels. A positioning disk is fitted on the rotating shaft. The outer peripheral surface of the positioning disk has a flat part and a groove for the latch to extend into. When the latch extends into the groove, the flat part is located at the bottom of the positioning disk, and the insertion part of the recessable number wheel is located outside the slot and is inserted into the slot when the recessable number wheel is pressed.

[0010] Preferably, the axial side surface of the unit digit wheel has a second mounting groove, the unit digit wheel has a circular hole that runs through the axial direction, and the positioning claw is located inside the first mounting groove or the second mounting groove.

[0011] Preferably, when the round hole and the semicircular channel where the insertion platform is located in the strip hole are coaxial, the recessable character wheel belonging to the strip hole is recessed upwards and downwards; when the round hole and the other semicircular channel in the strip hole are coaxial, the recessable character wheel belonging to the strip hole is at the same height as the unit character wheel.

[0012] Preferably, a knob is threaded onto the outer end of the shaft.

[0013] Compared with existing technologies, this utility model has the following beneficial technical effects: It facilitates the assembly of parts and allows the rotating shaft to be driven by rotating a knob, thus enabling the zeroing of multiple number wheels, making operation simple. Furthermore, after zeroing multiple number wheels, simply slightly moving the recessed wheel in a predetermined direction and then pressing it down adjusts it to an upward-downward-sinking state. This simple and convenient sinking operation enables true natural number encoding. Attached Figure Description

[0016] like Figures 1-9 As shown in the figure, the automatic numbering machine that can be rotated to zero and hidden in this embodiment includes a numbering machine body, a rotating shaft 14 installed on the numbering machine body, and a plurality of number wheels installed at equal intervals on the rotating shaft 14.

[0017] The multiple number wheels include a units digit wheel 22 for printing the units digit and several recessable number wheels 19 for printing other digits. A knob 18 is threaded to the outer end of a rotating shaft 14. Rotating the knob 18 drives the rotating shaft 14 to rotate, thus resetting the multiple number wheels to zero. The knob 18 has anti-slip texture to increase friction during manual operation. A slot 141 is provided on the outer circumference of the rotating shaft 14, and a one-way rotating ring 21 corresponding to each of the number wheels is fitted onto the shaft 14. One axial groove 190 is provided on the axial side surface of each recessable number wheel 19, and the recessable number wheel 19 has a through-hole 191. The inner side of the through-hole 191 has an inwardly protruding insertion platform 192 that fits into the slot 141. A V-shaped positioning claw 20 is rotatably mounted on each number wheel, specifically through a cylindrical boss on the number wheel, with the mounting position located in the middle of the positioning claw 20. When the insert plate 192 is inserted into the slot 141, one end of the inner side of the positioning claw 20 is located on the outer periphery of the one-way rotating ring 21, and the corresponding recessable character wheel 19 is recessed upwards. When the insert plate 192 is removed from the slot 141, one end of the inner side of the positioning claw 20 abuts against the outer periphery of the one-way rotating ring 21, and the outer end abuts against the inner periphery of the mounting groove 190. The corresponding recessable character wheel 19 is at the same height as the unit character wheel 22. At this time, the recessable character wheel 19 is not in an upward or downward recessed state, but is in a state for printing codes.

[0018] The positioning claw 20 is an elastic element, and the outer circumferential surface of the one-way rotating ring 21 has a locking tooth portion for pushing one end of the inner side of the positioning claw 20. When the numbering machine is not being zeroed, i.e., when the numbering machine is in normal use, the number wheel rotates to switch the bottom number for printing. The number wheel drives the positioning claw 20 to rotate. Due to its elasticity, the inner end of the positioning claw 20 will pass over the locking tooth portion and will not be blocked by the one-way rotating ring 21. However, when zeroing multiple number wheels in the numbering machine, the rotating shaft 14 is rotated in the same direction as the number wheels during normal use. The rotating shaft 14 drives the positioning claw 20 to rotate, and the locking tooth portion can be used to push the positioning claw 20, indirectly driving the number wheel to rotate. Since the locking teeth on the multiple one-way rotating rings 21 are distributed in the same direction, the multiple one-way rotating rings 21 can be used to push the multiple number wheels until the numbers on the outer circumferential surface are in the same position, and the final zeroing is achieved when the "0" position on the number wheel is adjusted to face downwards.

[0019] like Figure 6 and Figure 7 As shown, the strip-shaped hole 191 includes a straight channel and two semicircular channels respectively connected to both ends of the straight channel. The semicircular channels are adapted to the circumferential surface contour of the rotating shaft 14, and the insertion platform 192 is located inside one of the semicircular channels. Both the insertion platform 192 and the slot 141 are inclined.

[0020] The numbering machine body includes a latch 11 and a latch spring 12 that is elastically pressed on the outside of the latch 11 and the outside of multiple number wheels. A positioning disk 17 is fitted on the rotating shaft 14. The outer peripheral surface of the positioning disk 17 has a flat part and a groove for the latch 11 to extend into. When the latch 11 extends into the groove, the flat part is located at the bottom of the positioning disk 17, and the insertion part 192 of the recessable character wheel 19 is located outside the slot 141. When the recessable character wheel 19 is pressed, the insertion part 192 is inserted into the slot 141. That is to say, when the protrusion of the latch 11 extends into the groove, the user can know the state of the positioning disk 17 at this time. At this time, the insertion part 192 is located outside the slot 141 and is slightly misaligned. The user only needs to slightly move the recessable character wheel 19 in the predetermined direction, and then press the recessable character wheel 19 with the dial tool to insert the insertion part 192 into the slot 141, thereby adjusting the recessable character wheel 19 to the upward and downward state. The latch spring 12 presses on the latch 11, the latch 11 presses on the groove of the positioning plate 17, and the latch 11 also presses on the retractable character wheel 19. The insertion part 192 of the retractable character wheel 19 applies a certain pressure to the rotating shaft 14 at the slot 141. When the retractable character wheel 19 is not activated, the insertion part 192 of the retractable character wheel 19 will not move out of the slot 141 and will not release the upward and downward state.

[0021] When all number wheels are reset to zero (e.g., to 0000) and all recessable number wheels 19 are adjusted to their upward or downward position, this numbering machine will start from 1 instead of 0001 when printing codes. It can achieve true natural number encoding, printing numbers in the order of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, ..., 9999, instead of 0001, 0002, ..., 9999.

[0022] The unit digit wheel 22 has a mounting groove 220 on one side of its axial direction. For example... Figure 8 As shown, the unit character wheel 22 has a circular hole 221 extending axially. The positioning claw 20 is located inside either mounting groove one 190 or mounting groove two 220. When the circular hole 221 is coaxial with the semicircular channel where the insertion platform portion 192 of the strip hole 191 is located, the recessable character wheel 19 belonging to the strip hole 191 is recessed upwards and downwards. When the circular hole 221 is coaxial with another semicircular channel in the strip hole 191, the recessable character wheel 19 belonging to the strip hole 191 is at the same height as the unit character wheel 22. Both the recessable character wheel 19 and the unit character wheel 22 are in use and can be used for printing codes.

[0023] This embodiment facilitates the assembly of components such as the units digit wheel 22, the recessable digit wheel 19, the positioning claw 20, and the one-way rotating ring 21. The rotating shaft 14 can be rotated by rotating the knob 18, thus enabling the zeroing of multiple number wheels, making operation simple. Furthermore, after zeroing multiple number wheels, the zeroing status is known through the positioning plate 17. At this point, simply slightly move the recessable digit wheel 19 in a predetermined direction, and then press it down to insert the insertion plate 192 into the slot 141, thereby adjusting the recessable digit wheel 19 to an upward-downward-downward state. The downward-downward operation is simple and convenient, enabling true natural number encoding starting from code 1.

[0024] For the numbering machine body in this embodiment, the numbering machine body also includes a handwheel 1, a handle spring clip 2, a handle spring 3, a shell 4, a handle frame 5, a support frame 6, an ink cartridge connector 7, an ink cartridge 8, a moving claw frame 9, a moving claw mechanism 10, a stop frame 13, a double gear 15, and a triple gear 16. The connection relationship between the above parts is all prior art in the field of numbering machines, and the usage is also known to those skilled in the art of numbering machines. For reference, see the automatic numbering machine with rotatable rapid zeroing and automatic sinking and hiding disclosed in patent publication number CN222845067U and the hand-typed numbering machine with reset function and number wheel sinking function disclosed in CN209971927U. The rotating shaft 14 is rotatably mounted on the handle frame 5.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
