Description

Technical Field

[0001] The utility model relates to an improvement of a roller, in particular to an improvement of the connection between a bearing and plastic. Background Art

[0002] The load-bearing rollers currently in use are made of a combination of bearings and plastics. In order to make the bearings and plastics wrap firmly, the outer ring surface of the bearing and the inner ring surface of the plastics are bonded together by adhesives. However, there are two problems. First, it is impossible to know whether the bearings and plastics are firmly bonded to each other, and it can only be done by random inspection. Second, after a period of use, the adhesive is prone to debonding at the joints, which will cause damage to the roller and make it unusable.

[0003] Generally speaking, we will choose adhesives with better durability and anti-aging properties, and before bonding, we will polish, clean and dry the bonding surfaces to ensure that they are free of oil, dust and other impurities, and to ensure that the bonding surfaces are clean and dry to improve the bonding effect.

[0004] However, this method makes the manufacturing process complicated and the cost relatively high. There is no way to achieve consistency in the bonding strength of all products, and it is impossible to inspect all of them. Long-term use often leads to roller debonding. Utility Model Content

[0005] In order to overcome the shortcoming that the rubber wheel of the existing roller is easy to debond, the utility model provides an anti-debonding roller.

[0006] The utility model solves the technical problem with the following technical solution: an anti-debonding roller, comprising a bearing and a rubber wheel located outside the outer ring of the bearing, a left ring frame and a right ring frame are provided between the bearing and the rubber wheel, the left ring frame comprises a left guard plate and a left insertion frame located outside the left guard plate, the left guard plate leans against the left side of the outer ring of the bearing; the right ring frame comprises a right guard plate and a right insertion frame located outside the right guard plate, the right guard plate leans against the right side of the outer ring of the bearing; the left insertion frame and the right insertion frame are provided with frame grooves; the rubber wheel is injection molded on the left ring frame and the right ring frame. The left ring frame and the right ring frame have the same size.

[0007] The structure of the left guard plate is optimized. The left guard plate is divided into two parts: a left vertical plate and a left horizontal plate. The left vertical plate leans against the left side of the bearing outer ring, and the left horizontal plate leans against the outer side of the bearing outer ring. The right guard plate is symmetrically arranged in the same way.

[0008] The structure of the left insertion frame is optimized, and the left insertion frame includes a left vertical ring frame and a left horizontal ring frame; the right insertion frame is symmetrically arranged in the same manner.

[0009] The anti-debonding force is further provided. The frame groove is located on the connection part of the left vertical ring frame and the left horizontal ring frame.

[0010] In order to increase the anti-debonding effect to a certain extent, the left insertion frame is provided with a protrusion on the edge.

[0011] Furthermore, the protrusion is located on one side of the frame groove on the left insertion frame.

[0012] Preferably, the skeleton groove is a hole groove.

[0013] Preferably, the bearing is a single ball bearing with a sealing ring.

[0014] A preferred embodiment of a skeleton groove is that the skeleton groove is evenly arranged on the left insertion skeleton.

[0015] In order to prevent the bearing from sticking during glue injection, the inner diameter of the rubber wheel side hole is larger than the inner diameter of the left guard plate.

[0016] The utility model is the same as the roller of the prior art when in use, and no further description is given here. When the roller is produced, the outer rubber wheel is integrally injection-molded on the left ring frame, the outer ring of the bearing, and the right ring frame.

[0017] The rubber wheel in this product is not glue, but various materials coated on the outside, including PU, PA, POM, ABS, PP, PE and other plastic materials.

[0018] The beneficial effects of the utility model are as follows: 1. The rubber wheel is integrally injection molded on the left ring frame, the outer ring of the bearing, and the right ring frame. The rubber wheel is firmly buckled on the outer ring of the bearing through structural force, and is locked by the left and right guard plates at the outer ring of the bearing where the force is concentrated, so that it has a higher resistance to degumming, so that the roller rolls more than 1 million times under the load greater than normal use before degumming occurs. It can be used on various load-bearing rollers, and the performance is improved by more than 2.5 times. 2. Frame grooves are provided on the left and right insertion frames of the rubber wheel, which improves the connection force between the rubber wheel and the frame, making it less likely to degumming. The frame adopts an I-shaped structure, which has higher strength and better anti-peeling effect. 3. The skeleton has two advantages. The left and right skeletons are riveted on the outer ring and side of the bearing, and the bearing is wrapped in the two skeletons. As long as the skeleton and the outer ring plastic part are debonded, the bearing will not run out; the skeleton ring, that is, the structure wrapped around the outer ring of the bearing is I-shaped, which greatly increases the strength of the skeleton. There are also evenly distributed skeleton grooves in the I-shaped structure. This design greatly enhances the bonding strength between the outer ring plastic and the skeleton, making debonding more difficult. 4. This anti-debonding roller does not contain any chemical glue, is safe and environmentally friendly, uses integrated injection molding to produce low costs, good consistency, and guaranteed products.
