Description

A printing device for fabric manufacturing

Technical Field

The utility model relates to the technical field of cloth processing devices, in particular to a printing device for cloth manufacturing.

Background technique

Printing machines are widely used for printing processing of various materials. After development and improvement, the scope of application of printing machines is wider. Printing machines are also often used for printing and dyeing in traditional fabric processing and production. However, when printing fabrics, especially when using roller printing machines to ignite fabrics, the fixed position of the roller makes it impossible to adjust its height. The thickness of the fabrics to be printed is not uniform due to different production processes and production requirements. As a result, when printing through the printing roller, excessive pressure may damage the fabric, or too little pressure may lead to poor printing quality.

Detailed ways

The specific implementation of the utility model is further described in detail below with reference to Figures 1-6.

Embodiment 1, the technical solution is that when the utility model is in use, the provided printing roller 7 is rotatably mounted on the roller frame 5 through the roller shaft 6, and the roller frame 5 can be adjusted in height through the driving device 9, and the rotation of the screw 10 of the driving device 9 can drive the roller frame 5 to move vertically along the guide support device 4, so that the height of the roller frame 5 can be adjusted, and the printing roller 7 will also change in height with the roller frame 5, so that the height of the printing roller 7 is adjustable, and then the height of the printing roller 7 can be adjusted according to the processing requirements, and then the pressure between the printing roller 7 and the cloth is adjusted appropriately to ensure the printing quality. The provided guide support device 4 can not only limit the roller frame 5 to be adjusted only vertically under the drive of the driving device 9, but also increase the support capacity of the roller frame 5 by supporting, so as to maintain the stable operation of the printing roller 7. Further, the provided side support device further fixes and supports the roller frame 5 through the top screw 18 and the pressure plate 19 to ensure the stable operation of the printing roller 7. The utility model has a simple structure, is easy to use, and has strong practicality.

Embodiment 2, based on embodiment 1, specifically, when the utility model is in use, a conveyor belt 2 for conveying cloth is installed on the workbench 1, the cloth to be printed is placed on the conveyor belt 2, the cloth is made to run at a uniform speed with the conveyor belt 2, and the printing motor 8 is started to drive the roller shaft 6 on the roller frame 5 to rotate at a uniform speed, and then the printing roller 7 will also rotate at a uniform speed, when the conveyor belt 2 drives the cloth to pass through the printing roller 7 at a uniform speed, the rotating printing roller 7 can roll the cloth and complete the printing at the same time. In order to ensure the printing quality, it is necessary to adjust the height of the printing roller 7, so that the pressure of the printing roller 7 rolling the cloth is appropriate.

When adjusting the height of the printing roller 7, the stepper motor 11 of the driving device 9 is started to rotate forward. The stepper motor 11 on the frame 3 is a low-speed, high-torque motor. The low-speed operation of the stepper motor 11 facilitates real-time control of the height change of the roller frame 5. The high torque of the stepper motor 11 can prevent its output end from rotating and driving the screw 10 to rotate due to mechanical vibration and other reasons when it stops. The forward rotation of the stepper motor 11 will drive the screw 10 to rotate forward, and the forward rotation of the screw 10 will act on the roller frame 5 through the drive sleeve 12 and the connecting rod 13. The roller frame 5 is limited to move vertically through the guide sleeve 16 and the vertical shaft 15. Therefore, the forward rotation of the screw 10 will drive the roller frame 5 to move vertically downward through the drive sleeve 12 and the connecting rod 13. Correspondingly, starting the stepper motor 11 to reverse will drive the roller frame 5 to move vertically upward.

Embodiment 3, on the basis of embodiment 2, in order to ensure the stability of the roller frame 5 and thus the stable operation of the printing roller 7, a support spring 17 is provided on the support block 14 to support the guide sleeve 16, thereby increasing the stability of the roller frame 5. Furthermore, the provided top screw 18 (i.e., the bolt of the prior art) presses the roller frame 5 through the pressure plate 19 to further ensure the stability of the roller frame 5. When the height of the roller frame 5 is adjusted by the driving device 9, the top screw 18 should be rotated clockwise by the hand wheel 20 so that the top screw 18 drives the pressure plate 19 to separate from the roller frame 5, thereby facilitating the adjustment of the height of the roller frame 5. After the adjustment is completed, the top screw 18 is rotated counterclockwise so that the pressure plate 19 is close to the roller frame 5 again, thereby ensuring the stability of the roller frame 5.
