Description

Technical Field

[0001] The utility model relates to the technical field of mechanical transmission in the printing industry, in particular to a printing stable variable pitch transmission mechanism. Background Art

[0002] The printing equipment in the edge banding industry is assembled by rubber wheels, plate rollers, idler rollers, scrapers, gears and sprockets. The ink transfers the pattern of the plate roller to the rubber wheel through the plate roller, and the rubber wheel prints the pattern on the surface of the product through extrusion with the product.

[0003] At present, the traditional printing equipment is driven by sprockets or gears. Since the diameter of the printing rubber wheel is variable from 203 mm to 207 mm, the gear clearances are inconsistent, resulting in large jitters of the gears during the printing process due to clearance problems. Moreover, since the gear tooth speed ratio is a fixed value and the diameter of the printing rubber wheel is variable, there is forced slippage between the printing rubber wheel and the plate roller during the equipment transmission process, with large internal stresses, resulting in serious pulling and deformation of the pattern, and causing the whole equipment to vibrate, resulting in slippage and short durability of the printing rubber wheel. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages in the prior art that the transmission speed ratio and the printing speed ratio cannot be made consistent, and the vibration phenomenon occurring during the transmission process cannot be eliminated, resulting in a reduced service life of the printing rubber wheel and affecting the printing effect, and to propose a printing stable variable pitch transmission mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A printing stable variable pitch transmission mechanism, comprising:

[0007] A first frame, on one side of the first frame, a second frame is slidably arranged. On one side of the first frame, a main drive component is embedded. Inside the first frame, a printing plate roller is rotatably arranged on the inner ring of the main drive component. One end of the printing plate roller extending to the outside of the first frame through the inner ring of the main drive component is fixedly provided with a main drive hard wheel. On both sides of the inner wall of the second frame, the same connecting rod is rotatably arranged. A printing rubber wheel is fixedly arranged on the outside of the connecting rod. And one end of the connecting rod located outside the second frame is fixedly provided with a driven transmission rubber wheel. The main drive hard wheel and the driven transmission rubber wheel can be disengaged from transmission. On one side of the first frame, an upper mounting motor base is fixedly provided. On one side of the upper mounting motor base, a transmission motor is fixedly provided. The transmission motor is fixedly connected with the main drive hard wheel through a speed reducer.

[0008] In a possible design, on both sides of the inner wall of the first frame, above the printing plate roller, a plate roller scraper component is adjustably arranged. On both sides of the inner wall of the second frame, above the printing rubber wheel, a rubber wheel scraper component is adjustably arranged.

[0009] In a possible design, a driven top cone component is embedded on one side of the first frame, and the top cone of the driven top cone component can be disengaged from the top engagement with the printing plate roller.

[0010] In a possible design, the same rubber wheel sliding component is rotatably arranged on both sides of the second frame, and the rubber wheel sliding component can adjust the distance between the first frame and the second frame.

[0011] In a possible design, the printing plate roller and the driving hard wheel have the same diameter, and the driving hard wheel is a steel wheel.

[0012] In a possible design, the diameter of the driven transmission rubber wheel is larger than the maximum diameter of the printing rubber wheel, and the driven transmission rubber wheel is a soft wheel.

[0013] In this application, when starting to use, first, according to the thickness and width of the printing material, adjust the distance between the first frame and the second frame by adjusting the rubber wheel sliding component to ensure that the pressure between the printing plate roller and the printing rubber wheel is appropriate, and at the same time ensure that the pressure between the driven transmission rubber wheel and the driving hard wheel in contact is appropriate so that transmission can occur between the two. Subsequently, adjust the positions of the plate roller scraper component and the rubber wheel scraper component so that they can effectively scrape off the excess ink on the surfaces of the printing plate roller and the printing rubber wheel. Then, check whether the driven top cone component is in the correct position and be prepared to engage with the printing plate roller when needed to adjust its position or apply pressure;

[0014] Then, connect the device to the power supply and start the drive motor. The motor drives the driving hard wheel to rotate through the reducer. The rotational power of the driving hard wheel is transmitted to the printing plate roller through the driving component. While the driving hard wheel rotates, it also drives the driven transmission rubber wheel in transmission with it to rotate. While the driven transmission rubber wheel rotates, it drives the printing rubber wheel to rotate through the connecting rod. The surface of the printing plate roller is evenly coated with ink. The plate roller scraper component is responsible for scraping off the excess ink to ensure that only the pattern part retains the ink. When the printing plate roller rotates, the pattern on it is transferred to the printing rubber wheel through the ink, and then the printing rubber wheel prints the pattern on the material. The rubber wheel scraper component is used to clean the excess ink on the surface of the printing rubber wheel to maintain the printing quality;

[0015] During use, by adjusting the extrusion deformation amount between the driven transmission rubber wheel and the driving hard wheel, the transmission speed ratio and the printing speed ratio are made consistent to achieve variable-distance transmission. Moreover, the transmission is a soft surface contact, eliminating the vibration phenomenon that occurs during transmission, making the driven transmission rubber wheel have a longer service life and making the printing effect better.

[0016] The utility model has the following beneficial effects:

[0017] In the present utility model, through the arrangement of the driven transmission rubber wheel and the driving transmission hard wheel, the motor drives the driving transmission hard wheel to rotate through a speed reducer. While the driving transmission hard wheel rotates, it also drives the driven transmission rubber wheel in transmission with it to rotate. During use, the extrusion deformation amount between the driven transmission rubber wheel and the driving transmission hard wheel is used to achieve the same transmission speed ratio and printing speed ratio, realizing variable pitch transmission. Moreover, the transmission is a soft surface contact, eliminating the vibration phenomenon that occurs during the transmission process, making the service life of the driven transmission rubber wheel longer and the printing effect better.

[0018] In the present utility model, through the arrangement of the rubber wheel sliding component, according to the needs of the material thickness or printing effect, the distance between the first frame and the second frame can be changed at any time by adjusting the rubber wheel sliding component, accurately controlling the pressure between the printing plate roller and the printing rubber wheel, thereby optimizing the printing quality, reducing material waste, and improving the overall production efficiency.

[0019] In the present utility model, through the arrangement of the driven transmission rubber wheel and the driving transmission hard wheel, the extrusion deformation amount of the driven transmission rubber wheel is used to achieve the same transmission speed ratio and printing speed ratio. Moreover, the transmission is a soft surface contact, eliminating the vibration phenomenon that occurs during the transmission process, making the service life of the printing rubber wheel longer and the printing effect better.

Similarly, on both sides of the inner wall of the second frame 13 above the printing rubber roller 9, a rubber roller scraping component 6 is adjustably installed to clean the printing rubber roller 9.
