Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a flexographic composite cooling device which is convenient for position adjustment. Background Art

[0002] Most of the inks used in modern printing machines are UV drying inks, that is, after printing, they are solidified by strong ultraviolet rays and printed on paper or film materials. In modern printing machines, UV lamps are generally used to dry the ink after each printing. Because the power of modern UV lamps is relatively large, they not only emit strong light, but also high heat, which instantly heats the paper or film material to a very high temperature when it passes through. This is beneficial for ink drying, but it is a great harm to paper or film materials, because the tension of paper or film materials will change after heating, that is, under the same traction, the degree of stretching of paper or film materials is also different, which is not conducive to subsequent processing, so the dried paper or film materials need to be cooled in time.

[0003] Among the existing patents, the Chinese patent document with application number 201711413568.6 discloses a composite roller synchronous cooling structure of a composite machine, comprising: a frame, a first bearing seat symmetrically arranged at the front and rear ends of the frame, a rotating shaft rotatably arranged between the two bearing seats, a composite roller supported on the outside of the rotating shaft by a fixed frame, a cavity penetrating between the composite roller and the rotating shaft, the rear end of the rotating shaft extending out of the first bearing seat and connected to the motor shaft of the first servo reduction motor, the first servo reduction motor fixedly arranged on the frame, a bearing rotatably arranged on the first rotating shaft between the first bearing seat at the front end of the frame and the composite roller, a first driven gear arranged on the outer side of the bearing outer ring of the bearing, a drive motor arranged at the rear end of the frame, a first driving gear meshing with the first driven gear arranged on the motor shaft of the drive motor, and a sleeve arranged at the rear end of the bearing outer ring of the bearing. Although this patent document realizes the simultaneous cooling of the composite material during the process of the composite roller pressing the composite material, it does not have the characteristic of facilitating the adjustment of the composite position.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a flexographic composite cooling device which is easy to adjust the position.

[0008] Furthermore, the rotation drive mechanism includes a mounting seat mounted on the seat body, a motor mounted on the mounting seat, a driving wheel mounted on the output shaft of the motor, a driven wheel mounted on the cooling roller, and a transmission belt mounted outside the driving wheel and the driven wheel.

[0009] Furthermore, the rotation drive mechanism also includes a tensioning wheel and a limiting wheel which are rotationally connected to the outer side wall of the seat body respectively, the tensioning wheel rolls against the inner side wall of the transmission belt, and the limiting wheel rolls against the outer side wall of the transmission belt.

Both ends of the shaft rod are respectively inserted into the corresponding side mounting grooves of the shaft seat, and the end of the adjusting bolt is rotatably connected to the end of the shaft rod.

[0011] Furthermore, mounting grooves are provided in the middle of both side plates of the base body, and both ends of the UV dryer are located in the corresponding mounting grooves.

[0012] The beneficial effects of the utility model are as follows: in actual application, the printed material is dried by passing through the guide roller of the part, and the substrate after passing through the guide roller of the part is overlapped with the dried material and passes through the composite gap.

[0020] In actual application, the printed material (such as paper or film material, etc.) is passed through the guide roller 3 and then through the UV dryer 2 for UV light drying and curing. The substrate after passing through the guide roller 3 is overlapped with the UV light dried and cured material and passes through the composite gap. In this process, the cooling roller 4 cools the UV light dried and cured material, and the rotating drive mechanism 7 drives the cooling roller 4 to rotate. The rotating cooling roller 4 cooperates with the composite pressing roller 6 to composite the substrate and the material together. When the utility model is assembled, the sliding rod of the external machine slides through multiple movable bearings 10, and multiple support bearings 8 roll against the support plate of the external machine, so that the utility model can be adjusted relative to the external machine. The position adjustment is convenient and flexible, so that the composite position can be adjusted according to the actual situation to meet the needs of different usage scenarios.

[0021] In this embodiment, the rotation drive mechanism 7 includes a mounting seat 11 mounted on the seat body 1, a motor 12 mounted on the mounting seat 11, a driving wheel 13 mounted on the output shaft of the motor 12, a driven wheel 14 mounted on the cooling roller 4, and a transmission belt 15 mounted outside the driving wheel 13 and the driven wheel 14. The driving wheel 13 is located in the mounting seat 11; specifically, the support bearing 8 is located on the outside of the transmission belt 15 and is staggered, so that the transmission belt 15 and the support bearing 8 can work normally without interfering with each other. In actual application, the motor 12 drives the driving wheel 13 to rotate, and the rotating driving wheel 13 drives the cooling roller 4 to rotate under the cooperation of the transmission belt 15 and the driven wheel 14.
