Description

Technical Field

[0001] This utility model relates to the field of office equipment technology, specifically an automatic document page numbering machine. Background Technology

[0002] In the fields of archives management, bookbinding and document organization, it is a routine practice to stamp consecutive page numbers on paper documents;

[0003] Currently, the widely used page number machines mainly include two types: manual dial type and automatic increment type. They have the following drawbacks: the zeroing operation is inconvenient. Most devices lack a fast synchronous zeroing mechanism. When zeroing, each number wheel needs to be reset one by one, which is time-consuming and labor-intensive. In addition, the numbers are easily misaligned due to misoperation during the reset process. It is difficult to dial individually. When it is necessary to randomly set specific page numbers (such as skipping numbers or supplementing numbers), the existing devices are difficult to adjust the position of individual number wheels accurately and conveniently without affecting adjacent number wheels, resulting in poor flexibility. Utility Model Content

[0004] The purpose of this invention is to provide an automatic document page numbering machine with independent number wheel for precise adjustment and efficient synchronous zeroing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic document page numbering machine, comprising a body, a mounting frame slidably disposed inside the body, a rotating shaft rotatably disposed at the bottom of the mounting frame, a ratchet disc fixedly disposed on the surface of the rotating shaft, a numbering wheel rotatably disposed on the outer side of the ratchet disc, a transmission gear fixedly disposed on one side of the numbering wheel, a mounting plate fixedly disposed on the top of the back of the mounting frame, a mounting groove disposed at the bottom of the mounting plate, and a transmission gear rotatably disposed inside the mounting groove and meshing with the transmission gear.

[0006] A further feature of this invention is that a slide rail is fixedly provided on the side wall of the machine body, and a slide block that is slidably connected to the slide rail is fixedly provided on one side of the mounting bracket.

[0007] A further feature of this invention is that: a guide rod is fixedly provided at the top of the mounting bracket and slidably connected to the top of the machine body; a pressing handle is fixedly provided at the top of the guide rod; and a return spring sleeved on the outside of the guide rod is installed between the pressing handle and the top of the machine body.

[0008] A further feature of this invention is that a guide groove corresponding to the rotating shaft is provided on one side of the machine body, and a knob is installed at one end of the rotating shaft through the guide groove.

[0009] A further feature of this invention is that the number wheel has a rotating groove in the middle that rotates with the ratchet disc, the inner side of the rotating groove has a locking groove, and the surface of the ratchet disc has elastic locking teeth.

[0010] A further feature of this invention is that: the surface of the number wheel is provided with ten evenly spaced positioning grooves; a positioning rod is slidably provided at the bottom of the mounting plate; a positioning ball is fixedly provided at the end of the positioning rod near the number wheel; the positioning ball is made of metal; a limiting plate is fixedly provided at the end of the positioning rod away from the number wheel; and a return spring is provided between the limiting plate and the back of the machine body, sleeved on the outside of the positioning rod.

[0011] A further feature of this invention is that a second guide groove is provided on the back of the body, and the second guide groove corresponds to the position of the mounting plate.

[0012] In summary, this utility model has the following beneficial effects: The independent number wheel allows for precise adjustment, with the transmission gear directly meshing with the transmission gear plate of the number wheel. This allows for independent control of the rotation of any number wheel, enabling users to quickly and accurately set non-continuous page numbers (such as skipped or supplementary numbers) without disassembling or linking other wheel sets, significantly improving operational flexibility. Efficient synchronous zeroing is achieved by driving all number wheels synchronously through a ratchet disc, allowing all number wheels to be zeroed in a single operation, completely eliminating the need for individual wheel resets and effectively avoiding the risk of misalignment caused by manual operation. The elastic teeth of the ratchet disc and the grooves of the number wheels form a one-way meshing mechanism, ensuring precise driving of the number wheels when the rotating shaft rotates in the forward direction and automatic disengagement when rotating in the reverse direction. This design completely eliminates the possibility of unexpected retraction of high-position number wheels, ensuring the absolute accuracy of page number setting. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0020] Please see Figures 1-5 In this embodiment of the present invention, an automatic document page numbering machine includes a body 1. A mounting frame 2 is slidably disposed inside the body 1. A rotating shaft 202 is rotatably disposed at the bottom of the mounting frame 2. A pawl disc 208 is fixedly disposed on the surface of the rotating shaft 202. A number wheel 204 is rotatably disposed on the outer side of the pawl disc 208. Rotating the rotating shaft 202 drives the pawl disc 208 to rotate synchronously. With the cooperation of the pawl disc 208 and the number wheel 204, the number wheel 204 is driven to rotate, achieving synchronous zeroing. Reverse rotation of the rotating shaft 202 is not permitted. The number wheel 204 is driven to rotate. A transmission gear 2010 is fixedly provided on one side of the number wheel 204. A mounting plate 4 is fixedly provided on the top of the back of the mounting bracket 2. A mounting groove 405 is provided at the bottom of the mounting plate 4. A transmission gear 406 is rotatably provided inside the mounting groove 405 and meshes with the transmission gear 2010. When the transmission gear 406 rotates, it can drive the number wheel 204 fixedly connected to the transmission gear 2010 to rotate. The rotation of the number wheel 204 can be controlled independently to realize individual dialing and thus randomly select numbers.

[0021] In this embodiment, preferably, a slide rail 101 is fixedly provided on the side wall of the body 1, and a slide block 201 that is slidably connected to the slide rail 101 is fixedly provided on one side of the mounting frame 2. The sliding cooperation between the slide block 201 and the slide rail 101 plays a guiding and limiting role in the movement of the mounting frame 2.

[0022] In this embodiment, preferably, the top end of the mounting frame 2 is fixedly provided with a guide rod 3 that is slidably connected to the top end of the machine body 1, and the top end of the guide rod 3 is fixedly provided with a pressing handle 301. A reset spring 302 sleeved on the outside of the guide rod 3 is installed between the pressing handle 301 and the top end of the machine body 1. After the number wheel 204 is adjusted, pressing down the pressing handle 301 drives the mounting frame 2 to move downward for printing, and the mounting frame 2 can be reset under the action of the reset spring 302.

[0023] In this embodiment, preferably, one side of the body 1 is provided with a guide groove 102 corresponding to the rotating shaft 202, so that the movement of the rotating shaft 202 is not interfered with when the mounting frame 2 moves. One end of the rotating shaft 202 passes through the guide groove 102 and is equipped with a knob 203. The knob 203 can be used to quickly drive the rotating shaft 202 to rotate.

[0024] In this embodiment, preferably, the number wheel 204 has a rotating groove 206 in the middle that rotates with the pawl disk 208, and a slot 207 is provided on the inner side of the rotating groove 206. The surface of the pawl disk 208 is provided with elastic teeth 209. The engagement between the elastic teeth 209 and the pawl disk 208 can drive the number wheel 204 to rotate unidirectionally with the pawl disk 208. Rotating the rotating shaft 202 in the opposite direction will not drive the number wheel 204 to rotate.

[0025] In this embodiment, preferably, the surface of the number wheel 204 is provided with ten evenly spaced positioning grooves 205, and the bottom of the mounting plate 4 is slidably provided with a positioning rod 401. A positioning ball 402 is fixedly provided at the end of the positioning rod 401 near the number wheel 204. The positioning ball 402 is made of metal. When the positioning ball 402 is inserted into the positioning groove 205, it limits the position of the number wheel 204 and can make a sound to remind the staff that it has been rotated into place. A limiting plate 403 is fixedly provided at the end of the positioning rod 401 away from the number wheel 204. A second return spring 404 is provided between the limiting plate 403 and the back of the machine body 1 and sleeved on the outside of the positioning rod 401. The elasticity of the second return spring 404 can automatically engage when the positioning groove 205 of the number wheel 204 corresponds to the positioning ball 402.

[0026] In this embodiment, preferably, the back of the body 1 is provided with a guide groove 2 103, which corresponds to the position of the mounting plate 4. When the mounting frame 2 moves, it will not interfere with the mounting plate 4 and plays a guiding role in the movement of the mounting frame 2.

[0027] When in use, the knob 203 drives the rotating shaft 202 to rotate in the forward direction, which drives the pawl disk 208 fixed on it to rotate synchronously. The elastic teeth 209 on the surface of the pawl disk 208 are embedded in the slots 207 of the number wheels 204, pushing all the number wheels 204 to return to zero synchronously. When the rotating shaft 202 rotates in the reverse direction, the elastic teeth 209 slide off along the inclined surface of the slots 207, and the number wheels 204 remain stationary to prevent the high-digit numbers from reverting.

[0028] An external tool (such as a screwdriver) rotates the transmission gear 406, which meshes with the transmission gear 2010 of the target number wheel 204, driving the individual number wheel 204 to rotate independently. The remaining undriven number wheels 204 remain stationary because the pawl 208 disengages from the slot 207, thus achieving non-continuous page number setting. During the rotation of the number wheel 204, the positioning groove 205 passes through the positioning ball 402. When the positioning groove 205 aligns with the positioning ball 402, the return spring 404 pushes... The moving positioning rod 401 causes the metal positioning ball 402 to instantly engage with the positioning groove 205, producing a crisp sound from the metal collision and a tactile sensation, doubly confirming that the number wheel has rotated into place; pressing down the pressing handle 301 causes the guide rod 3 and the mounting bracket 2 to move vertically downwards along the slide rail 101, and the number wheel 204, fixed to the bottom of the mounting bracket 2, contacts the paper to complete the page number printing. After releasing the pressing handle 301, the return spring 302 pushes the mounting bracket 2 to precisely return to its original position along the slide rail 101, ready for the next printing.

[0029] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
