Description

Technical Field

[0001] This utility model relates to embossing equipment, specifically to an adjustable embossing mechanism. Background Technology

[0002] An embossing mechanism is used to imprint desired information, such as production date and batch number, onto a substrate. Its structure mainly includes an imprinting roller and a pressure roller. An imprinting block is mounted on the imprinting roller. The substrate is pressed through the pressure roller and imprinting roller to obtain the desired information. In traditional embossing mechanisms, the pressure roller is usually fixed. During actual use, significant friction is generated between the substrate and the pressure roller on the side where they are pressed together, easily causing wear to the substrate. Furthermore, the distance between the pressure roller and the imprinting roller is often fixed, making it impossible to adjust the imprinting depth during actual use, resulting in poor flexibility. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide an adjustable embossing mechanism for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] An adjustable printing mechanism includes a printing wheel and a pressure wheel that are fitted together. An printing block is mounted on the printing wheel. The printing wheel is connected to a first rotating shaft, which is driven by a first motor. The pressure wheel is mounted on a second rotating shaft. A first gear is connected to the first rotating shaft, and a second gear meshing with the first gear is connected to the second rotating shaft. The first rotating shaft is movably mounted on a mounting base, and the second rotating shaft is mounted on a first lifting seat. The first lifting seat is connected to a lifting adjustment assembly, and a locking assembly is provided corresponding to the first lifting seat.

[0006] The first lifting seat is provided with a guide post, and the lifting adjustment assembly includes an adjusting bolt rotatably disposed on the first lifting seat. An adjusting block is screwed onto the adjusting bolt. The adjusting block is slidably disposed in a guide groove on the first lifting seat, and one end of the adjusting bolt abuts against the mounting base.

[0007] The first lifting seat extends with a first clamping block and a second clamping block. The locking assembly includes a locking bolt, which passes through the first clamping block and is screwed to the second clamping block. The first and second clamping blocks can hold the side wall of the guide column.

[0008] The mounting base is connected to the second lifting base, the second lifting base is movably mounted on the movable frame and connected to the lifting drive assembly, and the movable frame is connected to the movable drive assembly.

[0009] The lifting drive assembly includes a second motor, the output end of which is connected to a lifting drive screw. The lifting drive screw is screwed to a second lifting seat, and a guide assembly is provided corresponding to the second lifting seat.

[0010] The moving drive assembly includes a third motor, the output end of which is connected to a moving drive screw. The moving drive screw is screwed to a moving frame, and a guide assembly is provided corresponding to the moving frame.

[0011] The adjustable printing mechanism described above uses a gear set to drive the first and second rotating shafts to rotate synchronously, which can effectively reduce friction between the substrate and the pressure roller, prevent the substrate from being worn during printing, and ensure printing quality. In addition, by driving the first lifting seat to lift slightly, the distance between the pressure roller and the printing roller can be adjusted, thereby adjusting the printing depth and adapting to substrates of different thicknesses, effectively improving its flexibility of use. Moreover, this slight distance adjustment will not affect the gear transmission between the first and second rotating shafts, allowing the equipment to operate normally. Attached Figure Description

[0017] As shown in the figure, the adjustable printing mechanism disclosed in this utility model includes a printing wheel 3 and a pressure wheel 1 that are configured to cooperate. The printing wheel 3 is provided with a printing block 2. The printing wheel 3 is connected to a first rotating shaft 5. The first rotating shaft 5 is connected to a first motor 9 for transmission. The pressure wheel 1 is provided on a second rotating shaft 4. A first gear 27 is connected to the first rotating shaft 5. A second gear 26 that meshes with the first gear 27 is connected to the second rotating shaft 4. The first rotating shaft 5 is movably mounted on a mounting base 8. The second rotating shaft 4 is mounted on a first lifting base 6. The first lifting base 6 is connected to a lifting adjustment component. A locking component is provided corresponding to the first lifting base 6.

[0018] Furthermore, a guide post 11 is provided on the first lifting seat 6. The lifting adjustment assembly includes an adjusting bolt 20 rotatably mounted on the first lifting seat 6, and an adjusting block 21 screwed onto the adjusting bolt 20. The adjusting block 21 is slidably mounted in the guide groove 22 on the first lifting seat 6, and one end of the adjusting bolt 20 abuts against the mounting base 8. Using the above technical solution, by controlling the rotation of the adjusting bolt 20, the adjusting block 21 can be driven to move. The adjusting block 21 will abut against the first lifting seat 6, thereby driving the first lifting seat 6 to rise or fall under the guidance of the guide post 11, adjusting the height of the pressure roller 1, and thus realizing the adjustment of the distance between the pressure roller 1 and the printing roller 3.

[0019] Furthermore, a first clamping block 18 and a second clamping block 23 extend from the first lifting seat 6. The locking assembly includes a locking bolt 19, which passes through the first clamping block 18 and is screwed to the second clamping block 23. The first and second clamping blocks can grip the side wall of the guide post 11. Using the above technical solution, tightening the locking bolt 19 can drive the first and second clamping blocks to grip the side wall of the guide post 11, using friction to lock the first lifting seat 6 and restrict its lifting. By unscrewing the locking bolt 19, the first and second clamping blocks can be released from the guide post 11, thereby adjusting the height of the first lifting seat 6.

[0020] Furthermore, the mounting base 8 is connected to the second lifting seat 10. Specifically, the mounting base 8 is connected to the gearbox 7, which is connected to the outer housing of the second motor 13. The outer housing of the second motor 13 is fixed to the second lifting seat 10, thus enabling the mounting base 8 to be installed on the second lifting seat 10. The second lifting seat 10 is movably mounted on the movable frame 17 and connected to the lifting drive assembly. The movable frame 17 is connected to the movable drive assembly. Specifically, the lifting drive assembly includes the second motor 13. The output end of the second motor 13 is connected to the lifting drive screw 12, which is screwed to the second lifting seat 10. A guide assembly is provided corresponding to the second lifting seat. The guide assembly is a guide post 11 that passes through the second lifting seat 10 and is connected to the outer housing of the second motor 13. By controlling the second motor 13 to drive the lifting drive screw 12 to rotate, the second lifting seat 10 can be driven to rise and fall under the guidance of the guide post 11, thereby adjusting the overall height of the embossing wheel assembly. The movable drive assembly includes a third motor 25, the output of which is connected to a movable drive screw 24. The movable drive screw 24 is screwed to a movable frame 17. A guide assembly is provided corresponding to the movable frame 17, including a slide block 15 connected to the movable frame 17. A slide rail 16 that cooperates with the slide block 15 is provided on the fixed frame 14. By controlling the third motor 25 to drive the movable drive screw 24 to rotate, the movable frame 17 can be moved under the guidance of the slide rail 16, thereby adjusting the overall horizontal position of the pressure roller assembly. Of course, in addition to the above structure, the lifting drive assembly and the movable drive assembly can also adopt common linear drive structures such as linear motors, gear and rack structures, sprocket and chain structures, and synchronous belt structures.

[0021] The working principle of this utility model is as follows: the printing substrate passes between the pressure roller 1 and the printing roller 3, and at this time, the first motor 9 drives the first rotating shaft 5 and the first gear 27 to rotate. The first gear 27 drives the second gear 26 and the second rotating shaft 4 to rotate, so as to realize the synchronous rotation of the pressure roller 1 and the printing roller 3, thereby cooperating to perform printing processing on the printing substrate; when it is necessary to adjust the printing depth, the lifting adjustment component is controlled to drive the first lifting seat 6 to lift slightly, thereby adjusting the distance between the pressure roller 1 and the printing roller 3, and realizing the adjustment of the printing depth.

[0022] This invention utilizes a gear train to drive the first and second rotating shafts, enabling synchronous rotation of the pressure roller and the printing roller. This effectively reduces friction between the substrate and the pressure roller, preventing wear on the substrate during printing and ensuring printing quality. Furthermore, by slightly raising and lowering the first lifting seat, the distance between the pressure roller and the printing roller can be adjusted, thereby regulating the printing depth and adapting to substrates of different thicknesses. This significantly enhances the flexibility of its use. Moreover, this slight distance adjustment does not affect the gear transmission between the first and second rotating shafts, ensuring normal operation of the equipment.
