All possible water entry locations in the bowl: printing opacity section of thick bamboo 10 and initiative end cover 20, position department sets up sealing washer 70 between the driven end cover 30, support the pressure to sealing washer 70 terminal surface through bolt tensioning clamp ring 60, make the terminal surface of sealing washer 70 tightly support and push down initiative end cover 20 on the one hand, the interior terminal surface of driven end cover 30, the deformation that radial grow takes place for on the other hand sealing washer 70 atress expands the inner wall of tight printing opacity section of thick bamboo 10, can effectively realize the sealing of roller, prevent inside water gets into the roller, the convenience is dismantled in the installation simultaneously, reduced the risk that leads to printing opacity section of thick bamboo fracture because of stress. For the light-transmitting cylinder 10 made of acrylic pipes, the sealing performance cannot be solved by a sealant filling mode in the prior art because the pipe diameter and the pipe orifice shape of the acrylic pipes are easy to deform, and the sealing ring 70 is made of soft materials, so that the sealing ring 70 can deform along with the deformation of the light-transmitting cylinder 10, and the sealing effect is good; for the light-transmitting cylinder 10 made of glass tube, the sealing ring 70 is made of soft material because glass is fragile, and the sealing ring 70 not only can play a role in sealing, but also can play a role in buffering and protecting the glass light-transmitting cylinder 10. In addition, the utility model has a very important function, the sealing ring 70 can provide enough friction force to make the light transmission cylinder 10 and the driving end cover 20 rotate synchronously, so that the light transmission cylinder 10 and the driving and driven end covers 20 and 30 are not required to be connected by bolts in the radial direction, on one hand, the light transmission cylinder 10 is prevented from being damaged or deformed by stress, and the sealing ring 70 is further ensured to be balanced in stress and reliable in sealing in the circumferential direction; on the other hand, the whole transparent roller has no fragmentary parts when viewed from the outside, is convenient to disassemble and assemble and is attractive and elegant.

As shown in fig. 7, the clamp ring 60 includes an outer ring body 61 abutting against the end surface of the seal ring 70, the outer diameter of the outer ring body 61 is smaller than the outer diameter of the seal ring 70, it is ensured that the end surface of the outer ring body 61 is extruded just the end surface of the ring body of the seal ring 70, an annular connecting sleeve 62 is convexly arranged towards the middle of the inner ring surface of the outer ring body 61, the width of the connecting sleeve 62 is smaller than the width of the outer ring body 61, clamping blocks 63 are uniformly arranged on the end surface of one side of the connecting sleeve 62 close to the driving end cover 20 and the driven end cover 30 in the circumferential direction, corresponding clamping grooves c are arranged on the inner side end surfaces of the driving end cover 20 and the driven end cover 30, and holes d for bolts. The cooperation of joint piece 63 and joint groove c card rank limits clamp ring 60 and the rotation of owner, driven

end cover

20, 30, and then the bolt passes hole d and is connected clamp ring 60 and owner, driven

end cover

20, 30, the restriction both at the ascending relative displacement of axial.

In order to ensure reliable positioning and locking, the clamping blocks 63 are uniformly arranged at intervals in the circumferential direction of the connecting sleeve 62, and the clamping grooves c are correspondingly arranged at 3 positions on the driving end cover 20 and the driven end cover 30.

Referring to fig. 8, the outer diameter of the sealing ring 70 is matched with the inner diameter of the light-transmitting cylinder 10, the inner ring surface of the sealing ring 70 is a tapered surface 71, and tapered bosses b matched with the tapered surface 71 are arranged on the inner sides of the driving end cover 20 and the driven end cover 30. The inner conical surface 71 of the sealing ring 70 is sleeved on the periphery of the conical boss b, when the bolt is tightened, the pressing ring 60 extrudes the end surface of one side of the sealing ring 70 to generate deformation which is enlarged in the radial direction to expand the inner wall of the light transmission cylinder 10, and the end surface of the sealing ring 70, which is far away from the pressing ring 60, abuts against the end surfaces of the inner sides of the driving end cover 20 and the driven end cover 30, so that the sealing reliability is ensured.

The outer contours of the driving end cover 20 and the driven end cover 30 are circular and the driving end cover 20 and the driven end cover 30 are arranged in the same core, annular grooves a with notches arranged towards the driving end cover 20 and the driven end cover 30 are uniformly formed in the end faces, close to the light transmission cylinder 10, of the driving end cover 20 and the driven end cover 30, and two end portions of the light transmission cylinder 10 are inserted into the annular grooves a. The annular groove a can be used for fixing the light transmission cylinder 10 stably and conveniently, and can also play a role in supporting and shaping the pipe orifice of the light transmission cylinder 10, so that the deformation of the pipe orifice of the light transmission cylinder 10 is effectively prevented, the sealing reliability of the sealing ring 70 is ensured, and water flow is effectively prevented from entering the roller.

Considering that the fixing bracket 40 is located in the cavity of the light-transmitting cylinder 10, and the fixing bracket 40 needs to be fixed with the color selector, the light-transmitting cylinder 10 rotates with the driving and driven

end caps

20, 30. Therefore, it is preferable that a through hole is provided at the center of the driving and driven
