Description

Technical Field

[0001] The utility model relates to the technical field of seals, in particular to an angle seal for a roller. Background Art

[0002] Seals are important components widely used in the engineering field. Their main function is to seal and protect various mechanical equipment and devices.

[0003] In glass fiber weaving, the fibers are placed on corresponding cylinders, which are then placed on rollers. In actual operation, the cylinders need to rotate independently of the rollers for weaving. Although existing seals used on rotating parts such as rollers have certain sealing properties, they are in contact with both the cylinder and the rollers at the same time. Therefore, when the cylinder rotates, additional resistance is added, which affects the actual operation of the cylinder and is not conducive to actual use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a roller angle seal to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a roller angle seal, comprising: a rubber component and a positioning sleeve, the rubber component comprising four sealing rings, a conical ring is fixedly installed on the side of the sealing ring, a limiting block is fixedly installed on the positioning sleeve, the side of the sealing ring away from the conical ring is in contact with the limiting block, the taper of the conical ring is set inward, and the edge of the conical ring connected to the sealing ring is larger than the edge of the conical ring away from the sealing ring.

[0006] Preferably, a roller shaft is arranged inside the positioning sleeve, and a through hole for passing the roller shaft is also opened on the positioning sleeve, and the through hole has a taper.

[0007] Preferably, the fitting relationship between the rubber component and the positioning sleeve is a transition fit, and the fitting relationship between the positioning sleeve and the roller shaft is an interference fit.

[0008] Preferably, the sealing rings are connected to each other via a conical ring, and the sealing rings are provided with through holes matching with the conical rings.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The roller angle seal is provided by setting a rubber component composed of four sealing rings, and then the rubber component is sleeved on a positioning sleeve, and the position of the positioning sleeve is limited on the roller shaft, wherein the matching relationship between the sealing ring and the positioning sleeve is a transitional match, so that the rubber component composed of the four sealing rings can rotate independently of the positioning sleeve, and then the rubber component is spliced ​​with the cylinder, and at the same time, the taper of the conical ring can ensure the concentricity of the rubber component composed of the four sealing rings, thereby ensuring the sealing of the seal composed of the sealing ring and the positioning sleeve, and can also reduce the rotational resistance caused by the entire seal, thereby ensuring the smoothness of the glass fiber weaving cylinder and ensuring the efficiency of the glass fiber weaving of the entire equipment.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 A roller angle seal comprises: a rubber assembly and a positioning sleeve 2, the rubber assembly comprises four sealing rings 1, a conical ring 11 is fixedly mounted on the side of the sealing ring 1, a limiting block 21 is fixedly mounted on the positioning sleeve 2, the side of the sealing ring 1 away from the conical ring 11 contacts the limiting block 21, the taper of the conical ring 11 is set inward, and the edge where the conical ring 11 is connected to the sealing ring 1 is larger than the edge where the conical ring 11 is away from the sealing ring 1, the sealing rings 1 are connected to each other through the conical ring 11, and the sealing ring 1 is provided with a through hole matched with the conical ring 11 to ensure the sealing of the rubber assembly composed of the four sealing rings 1 to meet the actual sealing requirements.

[0017] A roller shaft 3 is arranged inside the positioning sleeve 2. A through hole 22 for passing the roller shaft 3 is also provided on the positioning sleeve 2. The through hole 22 has a taper. The fitting relationship between the rubber component and the positioning sleeve 2 is a transition fit. The design of the tapered through hole 22 can make the fitting relationship between the positioning sleeve 2 and the roller shaft 3 an interference fit, thereby improving the tightness of the connection between the positioning sleeve 2 and the roller shaft 3, thereby ensuring that the position of the positioning sleeve 2 itself will not be offset after the roller shaft 3 runs.

[0018] Working principle: a rubber assembly composed of four sealing rings 1 is set, and then the rubber assembly is sleeved on the positioning sleeve 2. The limit block 21 fixed on the positioning sleeve 2 can limit the position of the rubber assembly to a reasonable assembly position. By utilizing the tapered through hole 22 inside the positioning sleeve 2 and the fact that the positioning sleeve 2 is made of elastic material, the matching relationship between the positioning sleeve 2 and the roller shaft 3 can be an interference fit, and the position of the positioning sleeve 2 is limited on the roller shaft 3. A tapered ring 11 is set on the sealing ring 1, so that the matching relationship between the sealing ring 1 and the positioning sleeve 2 is a transition fit. Therefore, the rubber assembly composed of four sealing rings 1 can rotate independently of the positioning sleeve 2, and then the rubber assembly is spliced ​​with the cylinder. At the same time, the taper of the tapered ring 11 can ensure the concentricity of the rubber assembly composed of the four sealing rings 1, thereby ensuring the sealing of the seal composed of the sealing ring 1 and the positioning sleeve 2, and reducing the rotational resistance caused by the entire seal.
