[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] This embodiment provides an engraving mechanism, such as Figure 1 As shown, the engraving mechanism includes a main body 1 and an engraving assembly 2. The main body 1 has a U-shaped cross-section and includes a base plate 11 and two baffles 12 spaced apart on the base plate 11. The main body 1 is provided with a central shaft 3, and one end of the central shaft 3 is fixedly connected to one baffle 12, and the other end of the central shaft 3 is fixedly connected to the other baffle 12. The engraving assembly 2 includes an engraving wheel 21, which is sleeved on the central shaft 3 and rotatably connected to the central shaft 3. The engraving wheel 21 is disposed between the two baffles 12.

[0042] Two baffles 12 are used to fix the central shaft 3 to form a bridge structure, thereby providing space to accommodate the engraving wheel 21 while ensuring the stability of the engraving wheel 21 between the two baffles 12. Multiple engraved characters 212 are spaced apart on the outer circumference of the engraving wheel 21. The engraved characters 212 can be individual blocks fixed to the outer circumference of the engraving wheel 21, or they can be directly engraved on the outer circumference of the engraving wheel 21. The engraving wheel 21 can rotate around the central shaft 3. Different angles of the engraving wheel 21 relative to the central shaft 3 result in different markings during engraving, thus distinguishing and organizing products produced in batches.

[0043] Preferably, the engraving assembly 2 includes multiple engraving wheels 21, and all multiple engraving wheels 21 are rotatably mounted on the central shaft 3. The engraving mechanism has an engraving direction. The operator can rotate the multiple engraving wheels 21 to adjust the normal of the engraved character 212 to be engraved on each engraving wheel 21 to be consistent with the engraving direction. When the engraving mechanism moves along the engraving direction and comes into contact with the surface of the product, the required mark can be engraved on the surface of the product.

[0044] like Figure 2 and Figure 3 As shown, in order to maintain the stability of the engraving wheel 21 during product engraving, the main body 1 is provided with a locking member 4, one end of which is rotatably connected to the main body 1. Each engraving wheel 21 has multiple slots 211 on its inner sidewall, and these slots 211 correspond one-to-one with multiple engraved characters 212 on the outer circumference of the engraving wheel 21. The locking member 4 can engage with the slots 211 of the engraving wheel 21 to lock its position. The engraved characters 212 can be numbers, letters, or other forms of characters.

[0045] It is worth noting that, for ease of adjustment, the multiple engraved characters 212 and multiple slots 211 on the engraving wheel 21 are evenly spaced, allowing the locking member 4 to simultaneously engage with one slot 211 of all the engraving wheels 21 at the same position to lock the position of all the engraving wheels 21. Furthermore, the slots 211 of the engraving wheels 21 correspond one-to-one with the engraved characters 212, and the position of the locking member 4 engaging with the slots 211 of the engraving wheels 21 does not change. As the engraving wheels 21 rotate, the locking member 4 can selectively engage with each slot 211 to lock the character corresponding to that slot 211 in a position where engraving can be performed. The locking member 4 is rotatably connected to the main body 1 via a rotating shaft 41.

[0046] like Figure 4 and Figure 5 As shown, the inner surface of the engraving wheel 21 is provided with multiple limiting protrusions 213 at intervals, and each of the multiple limiting protrusions 213 slides against the outer peripheral surface of the central shaft 3, forming a groove 211 between every two adjacent limiting protrusions 213. By using the multiple limiting protrusions 213 to slide against the outer peripheral surface of the central shaft 3, only relative rotation exists between the engraving wheel 21 and the central shaft 3, ensuring the stability of the engraving wheel 21 when engraving the product.

[0047] like Figure 4 and Figure 5 As shown, to facilitate operation of the locking element 4, the engraving mechanism also includes an unlocking component 5. The unlocking component 5 includes an unlocking element 51, which is movably positioned on the main body 1 to have an initial position and an unlocked position; as shown... Figure 4 As shown, when the unlocking component 51 is in the initial position, the locking component 4 can engage with the slot 211 to lock the engraved wheel 21, as shown. Figure 5 As shown, when the unlocking member 51 is in the unlocked position, the unlocking member 51 drives the locking member 4 to rotate so that the locking member 4 disengages from the slot 211.

[0048] The unlocking component 5 can lock or unlock the engraving wheel 21. The locking component 4 can be engaged in any slot 211 of the engraving wheel 21, thereby fixing the engraving wheel 21 at the required angle for engraving, ensuring stability during the engraving process. The operator can drive the locking component 4 to rotate by moving the unlocking component 51, causing the locking component 4 to disengage from the slot 211, so that the operator can rotate the engraving wheel 21 for adjustment. After adjustment, the locking component 4 can be re-engaged into the corresponding slot 211 of the engraving wheel 21.

[0049] The engraving mechanism can unlock the engraving wheel 21 by operating the unlocking component 51 with one hand, allowing the operator to adjust the engraving wheel 21 by one person, which improves production efficiency and reduces labor costs.

[0050] like Figure 2 and Figure 3 As shown, the engraving mechanism also includes a locking elastic element 6, which is configured to drive the locking element 4 into the slot 211. When the unlocking element 51 leaves the unlocking position and moves to the initial position, the locking elastic element 6 can drive the locking element 4 to move back to the position where it can be engaged in the slot 211, and apply an elastic force to the locking element 4 to ensure that the locking element 4 can lock the engraving wheel 21 and ensure stability during the locking process.

[0051] like Figure 2 and Figure 3 As shown, the unlocking component 5 also includes a reset elastic element 52, which is configured to drive the unlocking element 51 from the unlocked position to the initial position. After the operator has adjusted the engraving wheel 21 to its correct position, the unlocking element 51 is released. The unlocking element 51 can then move from the unlocked position to the initial position under the drive of the reset elastic element 52. At this time, the unlocking element 51 no longer restricts the movement of the locking element 4, allowing the locking elastic element 6 to drive the locking element 4 to move back to the position where it can engage with the slot 211, thus simplifying the operator's operation steps.

[0052] Preferably, the main body 1 has a mounting hole, one end of which extends through to the surface of the main body 1 and is blocked by the sealing member 13. The reset elastic member 52 is disposed in the mounting hole, one end of which abuts against the sealing member 13, and the other end of which abuts against the unlocking member 51. This structure facilitates the installation and removal of the reset elastic member 52 and facilitates the machining of the main body 1, thereby reducing processing costs.

[0053] In some embodiments, the unlocking element 51 can be a button, which can drive the locking element 4 to rotate by pressing the button, thereby unlocking the engraved wheel 21.

[0054] like Figure 4 and Figure 5 As shown, the unlocking member 51 is provided with an unlocking ramp 511, which slides against the free end of the locking member 4. During the process of the unlocking member 51 moving from the initial position to the unlocked position, the unlocking ramp 511 drives the free end of the locking member 4 to move, so that the locking member 4 rotates and disengages from the slot 211. As the unlocking member 51 moves, the unlocking ramp 511 can change the transmission direction, thereby driving the locking member 4 to rotate, so that the locking member 4 disengages from the slot 211.

[0055] Preferably, the unlocking member 51 is provided with a retaining plane 512, which is connected to the unlocking inclined plane 511. The angle between the retaining plane 512 and the rotation plane of the locking member 4 is greater than the angle between the unlocking inclined plane 511 and the rotation plane of the locking member 4. When the unlocking member 51 is in the unlocked position, the free end of the unlocking member 51 abuts against the retaining plane 512. At this time, the force exerted by the locking member 4 on the unlocking member 51 through the retaining plane 512 is less than the force exerted by the locking member 4 on the unlocking member 51 through the unlocking inclined plane 511. This reduces the amount of retaining force that the operator needs to apply to the unlocking member 51 during the adjustment of the engraving wheel 21, thereby reducing the operator's workload.

[0056] Preferably, the retaining plane 512 is perpendicular to the rotation plane of the locking member 4. When the locking member 4 abuts against the retaining plane 512, the locking member 4 will not exert a force on the unlocking member 51 to drive the unlocking member 51 to move. This allows the operator to overcome the elastic force of the reset elastic member 52, minimizing the operator's workload and ensuring the stability of the position of the locking member 4 when adjusting the engraving wheel 21.

[0057] In this embodiment, the unlocking member 51 is fixedly connected to a sliding rod 53, and the main body 1 has a sliding groove 14, in which the sliding rod 53 is slidably disposed. The cooperation between the sliding rod 53 and the sliding groove 14 can guide the locking member, ensuring that the unlocking member 51 can only move in a preset direction, preventing the unlocking member 51 from being driven off course by the reaction force of the locking member 4 when interacting with the locking member 4, and ensuring that when the unlocking member 51 moves to the unlocking position, the locking member 4 can be completely disengaged from the slot 211.

[0058] Preferably, both ends of the slide rod 53 extend through the unlocking member 51, and the portions of the main body 1 located on opposite sides of the unlocking member 51 are provided with grooves 14. One end of the slide rod 53 is slidably disposed in the groove 14 on one side of the main body 1 located on the unlocking member 51, and the other end of the slide rod 53 is slidably disposed in the groove 14 on the other side of the main body 1 located on the unlocking member 51, so as to improve the stability of the main body 1 in guiding the unlocking member 51.

[0059] It is worth noting that both the locking element 4 and the central shaft 3 are located within the engraved wheel 21. For example... Figure 6 As shown, in order to avoid interference between the locking member 4 and the central shaft 3, the central shaft 3 is provided with a through groove 31, and the locking member 4 is rotatably disposed in the through groove 31; in order to make the structure of the engraving mechanism more compact, the central shaft 3 is provided with a relief groove 32, and the unlocking member 51 is slidably disposed in the relief groove 32.

[0060] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
