Description

Technical Field

[0001] The utility model relates to the technical field of filter element production, and particularly relates to a pressing wheel limiting mechanism. Background Art

[0002] The pleated paper is an important part of the filter element. Affected by materials and the paper folding mechanism, there are mostly errors in the wave crests of the pleated paper. At present, a spring pressing mechanism is mostly used to flatten the protruding wave crests. However, limited by the errors of the wave crests of the pleated paper, it is difficult to adjust the spring pressure according to the wave crests. That is, when the adjustment position is too high, the spring pressing wheel cannot contact the pleated paper and cannot play a limiting role. When the adjustment position is low, some pleated paper just contacts the roller, but the higher pleated paper will be deformed. Only when the deformation of the pleated paper reaches a certain degree can the spring be compressed. In this way, it is always in a state of insufficient pressure or overpressure, and operators need to continuously debug.

[0003] Therefore, aiming at the deficiencies of the existing technology, it is necessary to design a pressing wheel limiting mechanism to solve the above problems. Summary of the Utility Model

[0004] In order to overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a pressing wheel limiting mechanism.

[0005] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a pressing wheel limiting mechanism, including a fixing plate, the bottom side of the fixing plate is connected with a pressing wheel group arranged along the feeding direction through a floating component, and the pressing wheel group is configured to be able to press against the wave crests of the pleated paper by its own weight.

[0006] The preferred technical solution is: the floating component is composed of n + 1 rotating shaft pins and n connecting pieces. The n + 1 rotating shaft pins are rotatably arranged on the fixing plate at equal intervals along the front - rear feeding direction. The n connecting pieces are connected to the first n rotating shaft pins in one - to - one correspondence. Each connecting piece is rotatably provided with a pressing wheel, and the n pressing wheels form the pressing wheel group.

[0007] The preferred technical solution is: the connecting piece is configured as a T - shaped structure and includes a pressing wheel connecting part, and pin connecting parts and limiting parts on both the front and rear sides of the pressing wheel connecting part. The pin connecting part is sleeved on the rotating shaft pin and fixedly connected to the rotating shaft pin, and the pressing wheel is rotatably arranged on the pressing wheel connecting part.

[0008] The preferred technical solution is: define two adjacent connecting pieces in the front - rear direction as the first connecting piece and the second connecting piece, and the limiting part of the first connecting piece abuts against the pin connecting part of the second connecting piece.

The bottom side of the fixing plate 1 is connected with a pressing wheel group 3 arranged along the feeding direction through a floating assembly 2. The pressing wheel group 3 is configured to be able to press against the peak of the pleated paper by its own weight.

[0018] As Figure 1 shown, in an exemplary embodiment of the present utility model, the floating assembly 2 is composed of n + 1 rotating shaft pins 21 and n connecting pieces 22. The n + 1 rotating shaft pins 21 are rotatably arranged on the fixing plate 1 at equal intervals along the front-back feeding direction. The n connecting pieces 22 are connected to the first n rotating shaft pins 21 in one-to-one correspondence. Each connecting piece 22 is rotatably provided with a pressing wheel 31. The n pressing wheels 31 form the pressing wheel group 3. It should be noted that there is one more rotating shaft pin 21 than the connecting piece 22, which is used to limit the last connecting piece 22 to ensure that the pressing wheel group 3 is horizontally arranged.

The pin connecting portion 222 is sleeved on the rotating shaft pin 21 and fixedly connected to the rotating shaft pin 21. The pressing wheel 31 is rotatably arranged on the pressing wheel connecting portion 221.

[0020] As Figure 1 shown, in an exemplary embodiment of the present utility model, two adjacent connecting pieces 22 in the front and back are defined as the first connecting piece and the second connecting piece. The limiting portion of the first connecting piece abuts against the pin connecting portion of the second connecting piece.

[0021] As Figure 1 shown, in an exemplary embodiment of the present utility model, the pressing wheel 31 is made of stainless steel material so that it can press flat the protruding peak of the pleated paper by its own weight.
