Technical Field

The invention relates to the technical field of mechanical equipment, in particular to a roller, a cam mechanism and a bottle blowing machine.

Background

The cam mechanism has wide application in the mechanical field, for example, in a bottle blowing machine, by designing the shape of a cam curved surface and adopting a roller to move along the surface of the cam curved surface, the periodic reciprocating motion of a specific mechanism can be realized, so that a blow-molded bottle blank can be accurately and quickly conveyed from a previous station to a next station. The standard bearing is usually adopted as the roller to contact with the cam curved surface, and the standard bearing moves at high speed at different accelerated speeds on the cam curved surface due to the fact that the standard bearing outer ring is made of steel, so that the surface of the cam curved surface needs to have certain hardness, and the cam curved surface needs to be coated with lubricating grease to reduce friction between the roller and the cam curved surface. At present, the matching structure of the cam and the standard bearing has the defects of high processing difficulty and high processing cost of the cam, and lubricating grease is easy to splash when the cam mechanism works, so that the aseptic requirement cannot be met.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the word "over" a first feature or feature in a second feature may include the word "over" or "over" the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under" a second feature may include a first feature that is directly under and obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 to 3, the roller of this embodiment includes a bearing 1 and a plastic-coated layer 2, a plurality of grooves 100 are provided on an outer ring 11 of the bearing 1, the plastic-coated layer 2 is injection-molded and wraps up on the surface of the outer ring 11, the plastic-coated layer 2 includes a body 21 and a flange 22, the body 21 is attached to an arc surface 111 of the outer ring 11, the flange 22 is located on a side surface 112 of the outer ring 11, and the flange 22 is perpendicular to the body 21 and extends toward the center direction of the bearing 1.

The roller of this embodiment is through setting up plastic-coated layer 2 on bearing 1's outer lane 11, makes the roller obtain good wear-resisting and shock resistance, makes the cam with the roller complex of this embodiment need not to have higher surface hardness, has reduced the processing cost of cam. By selecting proper injection molding materials, the friction coefficient between the roller and the cam can be greatly reduced, so that lubricating grease is saved, and the maintenance difficulty and the use cost are reduced.

Preferably, the groove 100 is disposed on the arc surface 111, and the body 21 is partially embedded in the groove 100. Because the arc surface 111 has a large surface area, the difficulty of machining the groove 100 on the arc surface 111 is low. In other embodiments, the side surface 112 is also provided with a groove 100 to increase the adhesion of the plastic-coated layer 2 on the bearing 1.

Preferably, the grooves 100 are intermittently disposed or form a closed curve on the surface of the outer race 11. The groove 100 may be provided as a plurality of grooves independent of each other, or may be provided in a continuous form. As shown in fig. 2, the groove 100 of the present embodiment forms a closed curve on the arc surface 111, so that the portion of the plastic-coated layer 2 embedded in the groove 100 is located at different positions in the width direction of the plastic-coated layer 2, and thus the plastic-coated layer 2 and the outer ring 11 cannot move relatively, so that the plastic-coated layer 2 and the bearing 1 are combined more tightly, and the abrasion caused by the friction between the plastic-coated layer 2 and the outer ring 11 is prevented.

In some embodiments, the grooves 100 form two parallel rings on the surface of the outer ring 11. As shown in fig. 4 and 5, the number of the grooves 100 is two and the grooves are arranged in parallel to each other, and two parallel circular rings are formed on the surface of the outer ring 11. The grooves 100 are arranged twice or more, so that the firm degree of the plastic-coated layer 2 attached to the bearing 1 can be greatly improved.

In other embodiments, as shown in fig. 6 and 7, the number of the grooves 100 is two, the two grooves 100 are disposed in a non-parallel manner, and the two grooves 100 form a closed curve, so that the plastic-coated layer 2 and the bearing 1 are more tightly combined.

In some embodiments, as shown in fig. 8, the grooves 100 are open along the axial direction of the bearing 1, so that relative movement between the plastic-coated layer 2 and the outer ring 11 is well prevented.

Specifically, the groove 100 penetrates through the surface of the outer ring 11, and the opening ends on both sides of the groove 100 are located on the side surface 112 of the outer ring 11, so that the part of the plastic-coated layer 2 embedded in the groove 100 penetrates through the arc surface 111 of the outer ring 11, and has a larger contact area, so that the plastic-coated layer 2 is more firmly attached to the outer ring 11.

Further, a plurality of grooves 100 are disposed parallel to each other. The grooves 100 in this embodiment are machined on the surface of the outer ring 11 by a milling process, and the grooves 100 are parallel to each other, so that each groove 100 can be machined without changing the milling angle, and the machining difficulty of the grooves 100 is reduced.

The embodiment of the invention also provides a cam mechanism which comprises the roller of any one of the embodiments, so that the surface hardness of the cam in the cam mechanism of the embodiment has no special requirement, the processing cost of the cam is reduced, and the plastic-coated layer 2 has lower hardness and certain elasticity, so that the rigid collision between the roller and the cam is avoided, and the service life of the cam mechanism is prolonged. The plastic coating layer 2 can also greatly reduce the friction coefficient between the roller and the cam by selecting proper materials, so that lubricating grease is saved in the cam mechanism of the embodiment, and the maintenance difficulty and the use cost are reduced.

The embodiment of the invention also provides a bottle blowing machine which comprises the cam mechanism of the embodiment, so that the bottle blowing machine has the characteristics of low cost and convenience in use. The aseptic requirement of the bottle blowing machine can be well met by omitting the lubricating grease of the cam mechanism.

The cam mechanism of the embodiment of the invention can also be used in other mechanical equipment comprising the cam mechanism, and is not limited to the bottle blowing machine of the embodiment.
