Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of papermaking, in particular to a guide roller shaft head anti-winding safety device. Background Art
[0002] When the paper machine is feeding paper, a large number of paper strips will fall on the shaft head of the guide roller. Due to the narrow, hot and high position, it is difficult to handle during the normal operation of the paper machine. As a result, more and more paper strips will be entangled on the shaft head. In the high temperature environment and the rotation of the guide roller itself, it is easy to cause spontaneous combustion. In addition, during the normal operation of the paper machine, the paper guide rope 7 may suddenly break due to wear and tear (such as Figure 1 As shown in the figure, the broken paper guide rope will be entangled on the step of the shaft head 92 of the guide roller 91 under the original inertia of movement, and then the paper guide rope will be melted at high temperature after the rotation friction to form a rubber block attached to the guide roller shaft head 92 and the bearing seat 8, which is extremely difficult to clean, and it is easy to cause accelerated wear of the shaft head, shorten the service life of the guide roller, and cause unplanned downtime.
[0003] In view of the above technical problems, the utility model proposes a new technical solution, which can prevent the paper strip and the paper guide rope from being wound around the shaft head of the guide roller. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a guide roller shaft head anti-winding safety device, aiming to solve the technical problem in the prior art that paper strips or broken paper guide ropes are easily entangled on the guide roller shaft head during the operation of the paper machine.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A guide roller shaft head anti-winding safety device comprises a flat plate, both ends of which are respectively connected with an arc plate, a fan-shaped plate is arranged upward on the rear side of the flat plate, and at least one connecting strip is arranged downward on the front side of the flat plate, and each connecting strip is respectively provided with a through hole.
[0007] Furthermore, in the guide roller shaft head anti-winding safety device, the flat plate is a rectangular plate, and the two arc-shaped plates are symmetrically arranged.
[0008] Furthermore, in the guide roller shaft head anti-winding safety device, in the projection of a plane parallel to the sector plate, the outer edge of the sector plate and the outer edges of the two arc plates are located on the same arc.
[0009] Furthermore, in the guide roller shaft head anti-winding safety device, in the projection of a plane parallel to the sector plate, the arc formed by the outer edge of the sector plate and the outer edges of the two arc-shaped plates is 180 degrees.
[0010] Furthermore, in the guide roller shaft head anti-winding safety device, the flat plate and the two arc-shaped plates are integrally formed.
[0011] Furthermore, in the guide roller shaft head anti-winding safety device, two connecting strips are arranged downward on the front side of the flat plate.
[0012] Beneficial effect: The utility model provides a guide roller shaft head anti-winding safety device. Compared with the prior art, the flat plate, arc plate and fan-shaped plate can have a good shielding effect on the guide roller shaft head, thereby preventing paper strips or broken paper guide ropes from being entangled on the guide roller shaft head during the operation of the paper machine, avoiding unplanned shutdowns and ensuring continuous production.

[0018] The utility model provides a guide roller shaft head anti-winding safety device. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0019] See also Figures 2 to 5 The utility model provides a guide roller shaft head anti-winding safety device. The attached drawings are only used to explain the structural principle and are not proportional to the actual product.
[0020] The guide roller shaft head anti-winding safety device comprises a flat plate 1, with an arc plate 2 connected to both ends of the flat plate, a fan-shaped plate 3 is arranged upward on the rear side of the flat plate, and at least one connecting strip 4 is arranged downward on the front side of the flat plate, and each connecting strip is provided with a through hole 40.
[0021] During actual assembly, align the through hole of the connecting strip with the corresponding connecting hole on the end cover 81 of the bearing seat 8, and screw in the bolt 82. It can be observed from the attached drawings that the connection between the connecting strip and the bearing seat of the guide roller shaft head 92 utilizes the original connecting hole on the bearing seat 8 of the guide roller shaft head 92, without opening a new connecting hole, and does not affect the normal installation of the end cover of the bearing seat.
[0022] Preferably, the flat plate is a rectangular plate, and the two arc-shaped plates are symmetrically arranged, which makes the production of the flat plate and the arc-shaped plate simpler.
[0023] Preferably, in the projection of a plane parallel to the sector plate (ie: Figure 5 The outer edges of the fan-shaped plate and the outer edges of the two arc plates are located on the same arc. This arrangement enables the outer edges of the fan-shaped plate and the outer edges of the two arc plates to better fit the corresponding guide rollers, thereby improving the anti-winding effect.
[0024] Preferably, in the projection of a plane parallel to the sector plate, the arc formed by the outer edge of the sector plate and the outer edges of the two arc-shaped plates is 180 degrees.
[0025] Preferably, the flat plate and the two curved plates are integrally formed.
[0026] Preferably, two connecting strips are arranged downward on the front side of the flat plate, which makes the connection between the guide roller shaft head anti-winding device and the corresponding guide roller shaft head bearing seat more stable.
[0027] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
