[0028] Referring to Figs. 1-3 , the driving device of hollow heating adsorption pipe includes platform 1, adsorption pipe 2, driving roller 3, driving assembly 4 and transmission assembly 5.Driving assembly 4 is used as a power output unit, and its output end is connected with driving shaft 6 and transmission assembly 5 respectively.Driving shaft 6 not only bears the function of power transmission, but also is externally sleeved with driving roller 3, and driving roller 3 can rotate under the driving of power to provide basic power support for the operation of the device.Transmission assembly 5 is responsible for further transmitting power to adsorption pipe 2, so that adsorption pipe 2 can complete the corresponding work task.

[0029] Specifically, the transmission assembly 5 is responsible for accurately transmitting power to the adsorption pipe 2, wherein the first driving synchronous pulley 511 of the first synchronous belt assembly 51 is arranged on the driving shaft 6 and connected with the first driven synchronous pulley 512 through the first synchronous belt 513; one end of the transmission shaft 524 of the second synchronous belt assembly 52 is connected with the first driven synchronous pulley 512, and the other end is connected with the second driving synchronous pulley 521, the second driving synchronous pulley 521 is connected with the second driven synchronous pulley 522 through the second synchronous belt 523, and finally the second driven synchronous pulley 522 is connected with the adsorption pipe 2, so that the adsorption pipe 2 can smoothly complete the corresponding work task.

[0030] The output end of the driving assembly 4 is connected with the driving shaft 6 and the transmission assembly 5, the outer part of the driving shaft 6 is sleeved with the driving roller 3, and the transmission assembly 5 is connected with the adsorption pipe 2.

[0031] Specifically, the adsorption pipe 2 is installed at the front end of the platform 1, which is beneficial to the adsorption operation of the material film; the driving roller 3 is arranged at the rear end of the platform 1, which cooperates with the adsorption pipe 2 to realize the conveying function of the material film.

[0032] The front and rear layout design of the adsorption pipe 2 and the driving roller 3 and the cooperative matching of each transmission assembly make the adsorption pipe accurately adsorb the material film, the driving roller synchronously complete the conveying action, the cooperation precision between the two is high, the position accuracy of the material film in the conveying process is guaranteed, and the printing precision and quality are improved.

[0033] The transmission assembly 5 includes a first synchronous belt assembly 51 and a second synchronous belt assembly 52. The first synchronous belt assembly 51 includes a first driving synchronous pulley 511, a first driven synchronous pulley 512 and a first synchronous belt 513, the first driving synchronous pulley 511 is arranged on the driving shaft 6, and the first driving synchronous pulley 511 is connected with the first driven synchronous pulley 512 through the first synchronous belt 513.

[0034] The second synchronous belt assembly 52 includes a transmission shaft 524, a second driving synchronous pulley 521, a second driven synchronous pulley 522 and a second synchronous belt 523, one end of the transmission shaft 524 is connected with the first driven synchronous pulley 512, the other end of the transmission shaft 524 is connected with the second driving synchronous pulley 521, the second driving synchronous pulley 521 is connected with the second driven synchronous pulley 522 through the second synchronous belt 523, and the second driven synchronous pulley 522 is connected with the adsorption pipe 2.

[0035] Specifically, the transmission mode of adopting a multi-stage synchronous belt assembly, combined with precise component connection, can ensure the stability and efficiency of power transmission during the transmission process, keep the material film conveying speed stable, avoid problems such as material film shaking and jamming caused by unstable power transmission, and effectively improve the continuity and reliability of the printing process.

[0036] In actual operation, the transmission assembly exhibits excellent performance. During the material film conveying process, the conveying speed fluctuation of the material film can be stably controlled, greatly improving the stability of the material film conveying. At the same time, due to the optimized design of the transmission components, the noise during device operation is greatly reduced compared to traditional equipment, creating a quieter working environment and significantly improving the performance and reliability of the entire equipment, laying a solid foundation for high-quality digital printing.

[0037] Further, the drive assembly 4 includes a drive motor 41 and a speed reducer 42. The drive motor 41 serves as a power source, and the high-speed rotating power output by it needs to be adjusted to meet the working requirements of the driving shaft 6, so the speed reducer 42 is connected. The speed reducer 42 can convert the high-speed, low-torque power output by the drive motor 41 into low-speed, high-torque power according to actual working requirements, and then stably transmit the power to the driving shaft 6 through the shaft coupling. This connection mode ensures the stability and reliability of power transmission, and can adapt to different working load requirements.

[0038] In addition, the drive assembly 4 also includes a drive mounting seat 43. One side of the drive mounting seat 43 is firmly connected and fixed to the rack, serving as a support and positioning the drive assembly 4 to ensure the stability of the entire drive system during operation; the other side connects the speed reducer 42, stably mounting the speed reducer 42 in the specified position, so that each part of the drive assembly 4 can work cooperatively.

[0039] Further, the adsorption pipe 2 includes a pipe body and a center rod, the center rod is arranged along the axial direction of the pipe body, and the center rod is arranged at the middle part of the pipe body. An annular cavity is formed between the pipe body and the center rod, and a separation part is arranged between the pipe body and the center rod. The separation part divides the annular cavity into a heating and drying cavity and a negative pressure adsorption cavity. The separation part is a rubber type partition plate. The good flexibility and sealing property of the rubber material can accurately separate the annular cavity into the heating and drying cavity and the negative pressure adsorption cavity, effectively prevent the airflow between the two cavities from interfering with each other, and ensure independent and efficient implementation of their respective functions.

[0040] The pipe body surface is provided with a through hole, and the through hole communicates the outside and the inside of the annular cavity. Specifically, the layout of the small holes of the through hole is optimized through fine fluid mechanics simulation. Through a large number of simulation calculations and actual tests, the best hole distribution and aperture parameters are determined. This optimized layout can ensure that the adsorption force is uniformly distributed on the surface of the pipe body, and the adsorption force can reach 30 N / m2 -1000N / m 2 , can precisely adsorb material film.

[0041] The working principle of the utility model is as follows: the drive is developed around power transmission, material film adsorption and conveying and ink drying, and each component cooperates to realize stable conveying and printing of material film in digital printing:

[0042] Power transmission: the drive assembly serves as a power source, and the drive motor 41 outputs power to the speed reducer 42. After the speed reducer 42 adjusts the rotating speed and torque, the power is transmitted to the driving shaft 6 through the shaft coupling. The driving shaft 6 rotates to drive the driving roller 3 outside the sleeve to rotate, and the first driving synchronous pulley 511 on the driving shaft 6 rotates synchronously, and the power is transmitted to the first driven synchronous pulley 512 through the first synchronous belt 513. The second driving synchronous pulley 521 is driven to rotate by the transmission shaft 524, and the second driven synchronous pulley 522 is driven by the second synchronous belt 523, and finally the power is transmitted to the adsorption pipe 2, realizing multi-stage stable transmission of power.

[0043] Material film adsorption and conveying: the adsorption pipe 2 is located at the front end of the platform 1, and the through holes on the surface of the pipe body are connected with the negative pressure adsorption cavity in the annular cavity. The micro suction pump in the negative pressure adsorption cavity works to generate a negative pressure of-10kPa--50kPa, so that the adsorption force is uniformly distributed on the surface of the pipe body (30N / m 2 -1000N / m 2 ), and the material film is precisely adsorbed to prevent offset and wrinkle. The driving roller 3 rotates at the rear end of the platform 1 and cooperates with the adsorption pipe 2 to realize stable conveying of the material film.

[0044] Ink drying: during the conveying process of the material film, the nano ceramic heating patch outside the center rod of the heating drying cavity plays a role. The power of the heating patch is 50W-500W and can be adjusted in sections, and can intelligently control the temperature in the range of 50℃-150℃ according to the printing speed and ink characteristics, so as to efficiently dry the ink on the material film. Compared with the traditional drying period, the drying period is shortened by 30%-50%, and the product quality and production efficiency are improved.
