[0036] Example:

[0037] See also Figure 1The bottom surface imprinting device in a preferred embodiment of the present invention includes a steel belt 1, a drive assembly 2, a first connecting member 3, a second connecting member 4, and a control assembly 5. The steel belt 1 may be printed with a pattern to be imprinted onto the material to be imprinted. The material to be imprinted may pass over the surface of the steel belt 1, and during this process, the pattern on the steel belt 1 is imprinted onto the bottom surface of the material to be imprinted. A glue dispensing member 9 may also be positioned above the steel belt to dispense UV glue required for subsequent processes onto the surface of the steel belt 1. This allows the material to be subsequently imprinted to be coated with the UV glue as it passes over the steel belt 1, facilitating subsequent curing.

[0038] Specifically, in the preferred embodiment, the two ends of the steel belt 1 are respectively connected to the first connecting member 3 and the second connecting member 4, the driving component 2 is connected to the first connecting member 3, the driving component 2 can drive the first connecting member 3 to rotate, the first connecting member 3 drives the steel belt 1 to move, and the steel belt 1 drives the second connecting member 4 to rotate.

[0039] It is understandable that in specific implementation, the drive component 2 can be a motor, such as Figure 1 As shown, in the preferred embodiment, the drive assembly 2 includes a right-angle reducer 201 and a servo motor 202, which provide power to the first connector 3. The motor's output shaft is connected to the first connector 3. When the motor is running, it drives the first connector 3 to rotate. The steel strip 1 is in a cyclical operation. The first and second connectors 3 and 4 are located at either end of the steel strip 1 to support the strip. The steel strip 1 circulates back and forth between the first and second connectors 3 and 4, achieving repeated imprinting.

[0040] In the preferred embodiment, the first connecting member 3 is a driving wheel and the second connecting member 4 is a driven wheel. This arrangement facilitates rotation under the drive assembly 2, and at the same time can better connect with the steel belt 1 and drive the steel belt 1 to circulate.

[0041] Furthermore, in a preferred embodiment, both the first connecting member 3 and the second connecting member 4 are provided with a limit member, and the steel belt 1 is provided with a limit hole 101 corresponding to the limit member, and the limit member can pass through the limit hole 101. In a specific implementation, the limit member can be a pin, and a plurality of pins are provided and evenly distributed on the surface of the driving wheel and the driven wheel at the same intervals. The limit holes 101 are also provided corresponding to the pins at the same intervals. In this way, when the first connecting member 3 and the second connecting member 4 move, the pins thereon pass through the limit holes 101 in sequence, so that the cooperation between the pins and the limit holes 101 is similar to the meshing between gears. The running accuracy of the steel belt 1 can be controlled by limiting, and at the same time, slippage between the steel belt 1 and the wheels can be eliminated.

[0042] Furthermore, in a preferred embodiment, the control component 5 is connected to the second connecting member 4, and the control component 5 can control the rotation of the second connecting member 4. It is understandable that the control component 5 uses existing mature technology and can control the second connecting member 4 to drive the force on both sides of the steel belt 1 to be uniform, and no excessive restrictions are made here. In specific implementation, the control component 5 includes a driving member 501 and a screw module 502. The driving member 501 drives the screw module 502 to move. The screw module 502 is connected to the second connecting member 4. The driving member 501 can also use a servo motor. In this way, the screw module 502 can be adjusted by the driving member 501 to adjust the second connecting member 4, and then the force on the steel belt 1 can be adjusted.

[0043] In the preferred embodiment, two control components 5 are provided and connected to both sides of the second connecting member 4. The two control components 5 can adjust the left and right sides of the second connecting member 4 and make the force exerted on the steel strip 1 uniform, thereby controlling the error of the steel strip 1.

[0044] In addition, a bottom surface imprinting device in a preferred embodiment further includes a host computer, a first detection member 6, and a second detection member 7, wherein the first detection member 6, the second detection member 7, the drive assembly 2, and the control assembly 5 are electrically connected to the host computer. It is understood that the host computer can use existing mature technology, and it can control the drive assembly 2 and the control assembly 5 while receiving and analyzing data from the first detection member 6 and the second detection member 7, without any excessive restrictions. At the same time, the host computer can control the control assembly 5 to adopt a torque mode during operation, which can ensure uniform force on both sides and thus control the operation error of the steel strip 1.

[0045] In the preferred embodiment, the first detection member 6 is connected to the first connecting member 3, and the second detection member 7 is connected to the second connecting member 4. The first detection member 6 and the second detection member 7 detect the running position of the steel strip 1 and transmit the detection data to the host computer. In this way, the real-time position data of the steel strip 1 can be detected and adjusted in the host computer as needed, and the drive assembly 2 can be adjusted by the host computer to adjust the operation of the steel strip 1.

[0046] In a preferred embodiment, both the first detection member 6 and the second detection member 7 are encoders. The first detection member 6 is frictionally connected to the first connecting member 3, and the second detection member 7 is frictionally connected to the second connecting member 4. The external encoders connected by friction can monitor the running position of the steel strip 1 in real time through encoder position feedback.

[0047] Preferably, if Figure 1As shown, in a preferred embodiment, the steel strip 1 includes a first surface 102 and a second surface 103, and a support member 8 is provided between the first surface 102 and the second surface 103. In specific implementation, the support member 8 can be a support roller. It can be understood that, as described above, the steel strip 1 is a belt-shaped object connected head to tail. In order to better connect with the first connecting member 3 and the second connecting member 4, it usually has two surfaces, namely the first surface 102 and the second surface 103. There is a large gap between the two surfaces due to the presence of the first connecting member 3 and the second connecting member 4. When one surface is above the other surface, due to the influence of gravity, the surface will sag, thereby affecting the embossing effect. Therefore, providing a support member 8 between the two surfaces to support the surface can ensure a good embossing effect during the embossing process. In order to achieve a better embossing effect, multiple support members 8 can be provided.

[0048] The bottom surface stamping device in this utility model controls the force applied to the steel strip, thereby minimizing strip errors. A stopper, in conjunction with a stopper hole, controls the strip's running accuracy and eliminates slippage between the strip and the wheel, resulting in a superior stamping effect. A host computer and encoder are also included to provide real-time control of the strip's movement, ensuring a controllable stamping process. Furthermore, a support member supports the stamping surface of the steel strip, further enhancing the stamping effect.

[0049] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
