Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0029] Reference Figures 1 to 5 The device in this embodiment consists of three main parts: an online wiping roller assembly 1, a wiping roller lifting platform assembly 2, and a wiping roller support assembly 3. The design of the online wiping roller assembly 1 is not the focus of this application; for details, please refer to patent CN223113666U. Its specific structure will not be described in detail here. The cooperation relationship between the other components is as follows:

[0030] 1. Coordination between the wiping roller lifting platform assembly 2 and the machine frame

[0031] Rodless cylinder 21: There are 4 sets in total, which are fixed on the frame. Their sliders are connected to the base plate 26 of the lifting platform and are responsible for driving the entire wiping roller assembly to rise and fall.

[0032] Lifting platform base plate 26: As the core load-bearing structure, it moves up and down through a rodless cylinder to support the wiping roller base plate 23.

[0033] 2. The fit between the wiping roller base plate 23 and the lifting platform base plate 26

[0034] Rolling bearing 27: Installed at the bottom of the wiping roller base plate 23 via rolling bearing pin 28, allowing the wiping roller base plate to slide horizontally on the lifting platform base plate, reducing frictional resistance.

[0035] Cam bearing 25: Installed on both sides of the lifting platform base plate 26, it cooperates with the guide structure of the wiping roller base plate 23 to ensure accurate guidance during movement.

[0036] Push cylinder 210: Fixed to one end of the lifting platform base plate 26, the cylinder mounting plate at the end of the piston rod contacts the edge of the wiping roller base plate 23, providing initial thrust to assist the movement of the wiping roller assembly.

[0037] Pin 24: Used to fix the bottom plate 23 of the wiping roller and the bottom plate 26 of the lifting platform to prevent displacement during operation.

[0038] 3. The fit between the online wiping roller assembly 1 and the wiping roller base plate 23

[0039] The online wiping roller assembly 1 is directly installed on the wiping roller base plate 23, and moves up, down and horizontally together with the wiping roller base plate.

[0040] When changing the nonwoven fabric, the wiping roller assembly can be pulled out as a whole onto the support assembly 3 to ensure sufficient operating space.

[0041] 4. Coordination between the wiping roller support assembly 3 and the wiping roller lifting platform assembly 2

[0042] Support frame base 31: Fixed on one side of the frame, used to support the wiping roller assembly pulled out from the lifting platform.

[0043] Guide plate 22: Installed on the support frame base 31, it cooperates with the cam bearing 25 of the wiping roller base plate 23 to ensure that the wiping roller assembly slides smoothly into the support frame.

[0044] Tank chain 33: Connects the lower support bracket 32 ​​of the tank chain to the support frame base and the upper support bracket 34 of the tank chain to the online wiping roller assembly, used to protect the cable or air pipe and ensure that the line is not damaged during movement.

[0045] 5. Work Process

[0046] When the nonwoven fabric of the wiping roller assembly needs to be replaced, the four rodless cylinders in the lifting assembly first lower the wiping roller assembly to the same height as the wiping roller support base. At this time, the pins fixing the wiping roller base plate to the lifting platform base plate are loosened. Cylinder 210 extends and pushes the wiping roller assembly out part of its length. Then, the wiping roller assembly is manually pulled onto the wiping roller support assembly, and the wiping roller base plate is fixed to the support frame base with pins. The replacement of the nonwoven fabric roll then begins. After replacement, the pins fixing the wiping roller base plate to the support frame base are loosened again. Under the action of the rolling bearings on the wiping roller base plate, the wiping roller assembly is pushed onto the lifting platform assembly along the guide plates on both sides and the cam bearings. Then, the pins are used to complete the positioning of the wiping roller base plate and the lifting platform base plate. Finally, the lifting platform rises to the working position, thus completing the replacement of the nonwoven fabric on the wiping roller.

[0047] It should be noted that the above description is merely a preferred application example of this utility model and is not intended to limit the scope of protection of this utility model. All technical solutions employing equivalent substitutions or equivalent transformations are within the scope of protection of this utility model.
