Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sealing bushing structure, and in particular to a multi-purpose sealing, dustproof, and paper-dustproof rotating wheel structure. Background Technology
[0002] During the processing of paper or other paper-based products, the edges are cut and shaped, resulting in a significant amount of paper scraps and dust accumulating in the processing environment and on the paper surface. These impurities are attracted to rotating structures, causing them to adhere and create damping at bearing locations or transmission connections. This severely impacts the operating efficiency of the processing equipment and can even lead to localized overheating, affecting normal operation. Currently, existing dustproof structures have poor overall sealing, often only effectively expelling contaminants and facilitating cleaning, but also requiring frequent and labor-intensive maintenance, failing to meet the demands of long-term processing use. Utility Model Content
[0003] The purpose of this utility model is to provide a multi-purpose sealing, dustproof, and paper-dustproof rotating wheel structure, which solves the technical problem that the overall sealing performance of the existing rotating wheel structure is poor and cannot effectively prevent dust and paper dust from entering. It achieves the technical effect of improving the sealing effect between the rotating wheel and the rotating shaft and effectively preventing dust and paper dust from entering.
[0004] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:
[0005] A multi-purpose sealed dustproof and paper scrap-proof rotary wheel structure includes a shaft seat and a guide seat. The shaft seat is cylindrical in shape, with a keyway on its inner wall along the axis of the shaft seat for transmission connection with a rotating shaft. Limiting grooves are provided at the upper and lower ends of the shaft seat. The limiting grooves are annular in shape and located on the outer side of the shaft seat. The guide seat has annular limiting protrusions inside for insertion and fixation with the limiting grooves. The guide seat has a threaded hole on its inner side, and a bolt is connected inside the threaded hole and fixed to the shaft seat. The guide seat is used to contact the processed paper and transmit power.
[0006] As an improvement, the bearing seat is made of metal, and there are four keyways that are equally spaced around the bearing seat axis. The guide seat is semi-circular in shape and is spliced along the limiting groove to form a disc. The guide seats are fixed by limiting pins, which can limit the diameter change of the bearing seat and ensure the sealing effect of the connection between the bearing seat and the bearing.
[0007] As an improvement, a mounting plate is sleeved on the outer side of the bearing seat. The mounting plate is set close to the guide seat and has a mounting groove and threaded hole on its inner side for detachable connection with the guide seat. An accessory connecting plate is provided on the mounting plate away from the guide seat. The accessory connecting plates are located on both ends of the mounting plate in the axial direction and are fixed in series by bolts. The accessory connecting plates have grooves for installing accessories, and the accessories can be connected and fixed by bolts.
[0008] The beneficial effects of this utility model are as follows: by setting the bearing seat structure, it can be fully matched with the bearing for connection and assembly. At the same time, the fixing of the guide seat can further limit the overall deformation of the bearing seat after long-term use, ensuring the sealing connection and transmission effect with the rotating shaft. By combining with the mounting plate and other structures, it can facilitate the installation of different accessories and achieve multi-purpose use. Attached Figure Description

[0013] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0014] like Figure 1 and Figure 2As shown, a multi-purpose sealed dustproof and paper scrap-proof rotary wheel structure includes a shaft seat 1 and a guide seat 2. The shaft seat 1 is cylindrical in shape, with a keyway on its inner wall along the axis of the shaft seat 1 for transmission connection with a rotating shaft. Limiting grooves 4, which are annular in shape and located on the outer side of the shaft seat 1, are provided at both the upper and lower ends of the shaft seat 1. The guide seat 2 has annular limiting protrusions inside for insertion and fixation with the limiting grooves 4. A threaded hole 3 is located on the inner side of the guide seat 2, and a bolt is connected inside the threaded hole 3 to fix it to the shaft seat 1. The guide seat 2 is used to contact and transmit power to the processed paper. The inner and outer surfaces of the shaft seat 1 are polished. The machining error at the keyway of the shaft seat 1 is ±0.05mm. The outer edge of the guide seat 2 is inclined towards the center, and its overall cross-sectional shape is triangular, which can fully adapt to the paper guiding requirements.
[0015] The bearing seat 1 is made of metal. It has four keyways, evenly spaced around the axis of bearing seat 1. The guide seat 2 is semi-circular in shape, joined together along the limiting groove 4 to form a disc. The guide seats 2 are secured with limiting pins to restrict changes in the diameter of bearing seat 1 and ensure a tight seal between bearing seat 1 and the bearing. The guide seat 2 is made of hard alloy with a wear-resistant and rust-proof coating, allowing it to fully cooperate with the rotating shaft for transport operations.
[0016] When in use, the guide seat 2 can be spliced on the outside of the bearing seat 1 and then fixedly connected by bolts; during installation, the bearing seat 1 can be sleeved on the outside of the rotating shaft, and the limiting groove 4 on one side can be fully matched with the rotating shaft to limit and fix it. During the rotation of the rotating shaft, the deformation of the bearing seat 1 will be limited by the guide seat 2, so as to achieve a tight fit connection with the bearing.
[0017] like Figure 3 As shown, a mounting plate 5 is sleeved and connected to the outer side of the bearing seat 1. The mounting plate 5 is set close to the guide seat 2, and its inner side has a mounting groove and threaded hole for detachable connection with the guide seat 2. An accessory connecting plate 6 is provided on the mounting plate 5 away from the guide seat 2. The accessory connecting plates 6 are located on both end faces of the mounting plate 5 in the axial direction and are fixed in series by bolts. The accessory connecting plates 6 have grooves for installing accessories, which can be connected and fixed by bolts. When installing accessories, it is necessary to ensure that the side close to the mounting plate 5 has a wall surface with a corresponding curvature to achieve full contact and fit with the wall surface of the mounting plate 5, and then tighten it with bolts for use.
[0018] When in use, after clamping and connecting on one side of the mounting plate 5, the accessory connecting plate 6 can be added at the corresponding position. First, assemble the accessory connecting plate 6 on one side and then install the accessory accordingly. Then, install the accessory connecting plate 6 on the other side and tighten the bolts.
[0019] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
