Description

Technical Field

[0001] This invention relates to the field of engraving equipment technology, and in particular to a multi-character engraving equipment. Background Technology

[0002] Mold engraving refers to stamping marks such as production date, batch number, or company logo onto a product. Taking the production date mold as an example, the mold needs to be adjusted accordingly as the production date changes.

[0003] Existing engraving equipment adjusts the type mold by controlling it with a motor. Due to the limited size of the engraving equipment, it can only engrave some short type molds. If the number of type molds to be engraved is increased, the number of motors needs to be increased. The overall structure becomes larger, which is not convenient for installation and maintenance, and greatly increases the cost.

[0004] Therefore, there is an urgent need for a multi-character engraving device to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-character engraving device that allows for the addition of more character characters without increasing the number of motors, thus avoiding an excessively large overall structure that would cause inconvenience in installation and maintenance.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A multi-character engraving device is provided, comprising: a base; a first transmission device mounted on the base, the first transmission device including a rack, a first gear and a first driving member, the rack being connected to the base, the first gear meshing with the rack, and the first gear being fixedly connected to the output shaft of the first driving member; a second transmission device connected to the first transmission device, and the first transmission device being capable of driving the second transmission device to move along a first direction, the second transmission device including an adjusting member; and a character mold device including a plurality of character mold units arranged along the first direction, the adjusting member being capable of adjusting any one of the character mold units along the first direction.

[0008] As an alternative to a multi-character engraving device, the second transmission device further includes a second driving member, which can drive the adjusting member to adjust the character unit.

[0009] As an optional solution for a multi-character engraving device, the character mold device further includes a transmission component, which includes a plurality of second gears arranged along the first direction. The plurality of second gears are arranged in a one-to-one correspondence with the plurality of character mold units. The adjusting component is an adjusting gear, which can mesh with any one of the second gears to adjust the corresponding character mold unit.

[0010] As an optional solution for multi-character engraving equipment, each character unit includes a third gear and a character mold piece, the third gear and the character mold piece are fixedly connected, and each third gear is meshed with the corresponding second gear.

[0011] As an optional solution for a multi-character engraving device, the multi-character engraving device also includes multiple limiting components, which are connected one-to-one to multiple second gears.

[0012] As an optional solution for a multi-character engraving device, the limiting component includes a limiting member and an elastic member connected to the limiting member. The limiting member abuts against any one of the tooth slots of the second gear to prevent the second gear from rotating.

[0013] As an alternative to a multi-character engraving device, the second transmission device further includes a transmission body, through which the first transmission device and the second transmission device are connected.

[0014] As an alternative solution for a multi-character engraving device, the multi-character engraving device further includes a support frame, which is connected to the base, and the character mold device is mounted on the support frame.

[0015] As an alternative to a multi-character engraving device, the support frame includes a connecting shaft arranged along a first direction, and the transmission body is connected to the connecting shaft.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings, not all of them.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] like Figures 1 to 3 As shown, the multi-character engraving equipment of this embodiment includes a base 1, a first transmission device 2, a second transmission device 3, and a character mold device 4. The first transmission device 2 is mounted on the base 1 and includes a rack 21, a first gear 22, and a first drive member 23. The rack 21 is connected to the base 1, the first gear 22 meshes with the rack 21, and the first gear 22 is fixedly connected to the output shaft of the first drive member 23. The second transmission device 3 is connected to the first transmission device 2, and the first transmission device 2 can drive the second transmission device 3 to move along a first direction. The second transmission device 3 includes an adjusting member 31. The character mold device 4 includes multiple character mold units 41 arranged along the first direction. The adjusting member 31 can adjust any one of the character mold units 41 along the first direction. The first transmission device 2 can drive the adjusting member 31 to move along the first direction, thereby enabling the adjusting member 31 to adjust any one of the character mold units 41 along the first direction. When adding character mold units 41, there is no need to increase the number of motors, avoiding an increase in the overall structure of the multi-character engraving equipment, which would cause inconvenience in installation and maintenance, and reducing production costs.

[0034] like Figure 2 As shown, the rack 21 is arranged along the first direction. When it is necessary to adjust the character pattern of the character pattern unit 41, the first driving member 23 drives the first gear 22 to rotate. The first gear 22 meshes with the rack 21, thereby driving the second transmission device 3 to move along the first direction. This allows the adjusting member 31 to adjust any one of the character pattern units 41 along the first direction. When the number of character pattern units 41 is increased along the first direction, there is no need to increase the number of motors; the adjustment of the character pattern units 41 can be satisfied simply by adjusting the adjusting member 31. The multi-character pattern engraving equipment of this embodiment has a simple structure, is easy to install and maintain, and can achieve high-precision positioning by driving the adjusting member 31 through the first gear 22 and the rack 21.

[0035] It is worth noting that in this embodiment, the first driving component 23 is a servo motor, which has high control precision. In other embodiments, the first driving component 23 may also be a stepper motor, a hydraulic pump, a hydraulic cylinder, etc., and no specific limitation is made here.

[0036] Furthermore, the character mold device 4 also includes a transmission assembly 42, which includes multiple second gears 421 arranged along a first direction and a transmission shaft 422. The multiple second gears 421 are all connected to the transmission shaft 422, and each of the multiple second gears 421 corresponds one-to-one with a multiple character mold unit 41. The adjusting member 31 is an adjusting gear, which can mesh with any one of the second gears 421 to adjust the corresponding character mold unit 41. By rotating the adjusting gear, the second gears 421 are driven to rotate, causing the character mold unit 41 to be adjusted to the desired character. The adjustment of each character mold unit 41 can be achieved through the adjusting gear.

[0037] Furthermore, the second transmission device 3 also includes a second driving member 32, which can drive the adjusting member 31 to rotate, thereby adjusting the character module unit 41. After the second driving member 32 drives the adjusting gear to rotate, the adjusting gear meshes with the second gear 421, resulting in high transmission accuracy and enabling high-precision adjustment, while maintaining a simple structure. In this embodiment, the second driving member 32 is a servo motor, which offers high control accuracy. In other embodiments, the second driving member 32 can also be a stepper motor, a hydraulic pump, a hydraulic cylinder, etc., and is not specifically limited here.

[0038] Preferably, each character mold unit 41 includes a third gear 411 and a character mold piece 412, the third gear 411 and the character mold piece 412 are fixedly connected, and each third gear 411 is meshed with a corresponding second gear 421. Figure 2 and Figure 3 As shown, characters are engraved on the circumference of the character mold piece 412. The character mold piece 412 is fixedly connected to the third gear 411. As the second gear 421 rotates, it will drive the third gear 411 and the character mold piece 412 to rotate circumferentially, thereby adjusting the character mold piece 412 to the character to be engraved.

[0039] More preferably, the number of characters on the character mold piece 412 is the same as the number of teeth on the third gear 411, resulting in higher positioning accuracy of the character mold piece 412 and enabling more precise adjustment to the required character. In this embodiment, the number of character mold units 41 can be increased or different character mold pieces 412 can be replaced according to the content to be engraved.

[0040] Furthermore, the multi-character engraving device also includes multiple limiting components 5, which are connected one-to-one with multiple second gears 421. The limiting components 5 can restrict the rotation of the second gears 421, thereby restricting the rotation of the third gear 411 and preventing the character mold piece 412 from rotating during the engraving process, which would affect the engraving effect.

[0041] Preferably, the limiting component 5 includes a limiting member 51 and an elastic member 52 connected to the limiting member 51. The limiting member 51 abuts against any one tooth groove of the second gear 421 to prevent the second gear 421 from rotating. Figure 3 As shown, when replacing the character mold piece 412, the rotation of the adjusting member 31 drives the second gear 421 to rotate. When the second gear 421 rotates, it compresses the elastic member 52. Specifically, the tooth tip of the second gear 421 contacts the limiting member 51, causing the elastic member 52 to be compressed. When the elastic member 52 is compressed, the limiting member 51 has no limiting function, and the character mold piece 412 can be adjusted for the engraved content. When the character mold piece 412 is adjusted to engrave the character, the elastic member 52 changes from a compressed state to an elastic state, causing the limiting member 51 to abut against the tooth groove of the second gear 421, preventing the second gear 421 from rotating abnormally when the character mold piece 412 is in use or working state, thus achieving the limiting effect.

[0042] In this embodiment, the limiting component 5 also includes a headless screw 53, which is connected to the elastic element 52. On the one hand, the headless screw 53 can limit the position of the elastic element 52 and prevent the elastic element 52 from popping outward due to excessive elasticity; on the other hand, the headless screw 53 can be screwed into the threaded hole during use, so that the overall appearance of the multi-character engraving device is flat and beautiful.

[0043] Preferably, one end of the limiting member 51 is arc-shaped, which can better abut against the tooth groove of the second gear 421.

[0044] In this embodiment, the elastic element 52 can be a spring. In other embodiments, the elastic element 52 can also be an elastic sheet, etc., and no specific limitation is made here.

[0045] Furthermore, the second transmission device 3 also includes a transmission body 33, through which the first transmission device 2 and the second transmission device 3 are connected. Specifically, the transmission body 33 is provided with a first through hole, through which a first driving member 23 passes and is connected to a first gear 22. During the transmission process between the first gear 22 and the rack 21, the transmission body 33 is driven to move along a first direction. The transmission body 33 is also provided with a second through hole, through which a second driving member 32 passes and is connected to an adjusting member 31. During the movement of the transmission body 33 along the first direction, it can drive the second driving member 32 and the adjusting member 31 to move along the first direction, thereby enabling the adjusting member 31 to adjust the character module unit 41 along the first direction.

[0046] Preferably, the multi-character engraving equipment further includes a support frame 6, which is connected to the base 1, and the character engraving device 4 is mounted on the support frame 6. Figure 1As shown, in this embodiment, the support frame 6 consists of two parallel support plates, with the typeface device 4 mounted between them, facilitating its maintenance and assembly. In this embodiment, the support frame 6 is detachably connected to the base 1.

[0047] Preferably, the support frame 6 includes a connecting shaft 61 arranged along the first direction, and the transmission body 33 is connected to the connecting shaft 61. Specifically, the transmission body 33 is provided with a third through hole, and the transmission body 33 is sleeved on the connecting shaft 61 through the third through hole, so that the movement of the transmission body 33 along the first direction is more stable.

[0048] In this embodiment, the multi-character engraving device also includes a limit sensor 7, which is mounted on the base 1 to prevent the first transmission device 2 from overtraveling. The limit sensor 7 can detect the movement position of the first gear 22 and whether the first gear 22 has reached a specific position or position range, thus preventing the first gear 22 from overtraveling and colliding.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
