[0002] A circular loom refers to an industrial device for weaving tubular fabrics. In the existing plastic circular loom, a roller assembly is arranged between the upper door ring and the lower door ring to form a rolling track for the shuttle to run. The warp threads pass through the door ring assembly, and the shuttle runs at a high speed along the inner circle of the door ring assembly to make a circular motion, realizing the cross-weaving of the warp threads and the weft threads.

[0003] The function of the shuttle in the plastic circular loom is to thread the weft threads. It is an important part of the circular loom and is extremely easy to be damaged. It requires light weight and wear resistance. The shuttle board of the existing shuttle is usually integrally formed of aluminum, and the shuttle wheel is usually arranged on the shuttle board and drives the shuttle board to rotate at a high speed. The shuttle wheel usually includes a bearing and an external plastic part. Since the shuttle wheel rotates rapidly during the high-speed movement of the shuttle, a large amount of heat is generated. Therefore, the outer layer of the existing shuttle wheel usually selects high-temperature-resistant nitrile materials, but its disadvantage is that it is not wear-resistant and its service life is short. Therefore, it is necessary to stop the machine frequently to replace the shuttle wheel, which is time-consuming and laborious and greatly increases the production cost. Summary of the Utility Model

[0026] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings:

[0027] Consisting of Figure 1 Combined with Figures 2-6 As shown in the figure, a shuttle wheel includes:

[0028] An outer ring 1 for fitting with the frame of a circular loom;

[0029] A bearing 2 provided on a shuttle plate 4 and used to support the rotation of the outer ring 1;

[0030] A connecting member 3 for connecting the outer ring 1 and the bearing 2, and a heat dissipation portion is provided on the connecting member 3. The beneficial effect of the present utility model is that a heat dissipation portion is provided on the shuttle wheel, which can dissipate heat from the shuttle wheel moving at high speed. The structure is simple and the service life of the product is prolonged. The present utility model also has the advantages of simple structure, convenient assembly, reliable operation and long service life. Usually, the heat dissipation part is a groove or a hole. In this way, during the movement of the shuttle plate and the rotation of the shuttle wheel, the air flow can dissipate heat through the hole or the groove, taking away the heat on the outer ring, and at the same time, the material can be reduced and the production cost can be lowered. Of course, heat dissipation can also be achieved by setting heat dissipation ribs and other methods.

[0031] The heat dissipation portion is a heat dissipation hole 31, and there are multiple heat dissipation holes 31, and different heat dissipation holes 31 are circumferentially provided on the connecting member 3. Specifically, the heat dissipation holes 31 are circular, square, triangular, elliptical and / or polygonal. Of course, in the actual production process, usually the heat dissipation holes are equidistantly arranged, which is convenient for processing. Of course, they can also be non-equidistantly arranged. Usually, circles can be selected, such as the structure of the shuttle wheel in Embodiment 1 (attached Figure 2 shown), of course, in the actual production process, it can also be achieved by using a combination of different hole shapes.

[0032] The heat dissipation holes 31 are strip-shaped and are circumferentially evenly distributed on the connecting member. Such as the structure of the shuttle wheel in Embodiment 2 (attached Figure 3 shown). The hole shapes in Embodiment 1 and Embodiment 2 are convenient for processing and the strength of the connecting member is high, which is the preferred way of the present utility model. Of course, it can also be achieved by using a combination of different hole shapes or by using a non-equidistant method.

[0033] The heat dissipation portion includes heat dissipation holes 31 and heat dissipation grooves 32. There are multiple heat dissipation holes 31, and the heat dissipation grooves 32 are arranged to communicate with different heat dissipation holes 31. Such as the structure of the shuttle wheel in Embodiment 3 (attached Figure 4 shown). Embodiment 3 is further provided with a heat dissipation groove compared with Embodiment 1. This groove can quickly take away the heat on the inner and outer sides of the connecting member, play a reliable role in dissipating heat from the outer ring and the bearing, and prolong the service life of the product.

[0034] The connecting member 3 is provided with a plurality of connecting parts 33, and heat dissipation holes 31 are formed between the connected connecting parts 33. The side surface of the connecting member is recessed inward to form a heat dissipation groove 32. Figure 5 As shown in the figure, in the fourth embodiment, a larger hollow heat dissipation hole is formed, and a heat dissipation groove is provided at the same time. The groove can quickly take away the heat inside and outside the connector, and reliably dissipate heat for the outer ring and the bearing, thereby extending the service life of the product. The heat dissipation hole is larger, which is more conducive to air circulation and has a good heat dissipation effect. In addition, such a structure makes the connection block in the shape of an "I" character, which enhances the connection strength at the connection block, reduces the overall volume and weight of the product, and reduces the production cost.

[0035] The plurality of connecting parts 33 are arranged in layers, and the projections of the connecting parts 33 of different layers in the axial direction of the connecting member 3 are arranged in the heat dissipation holes 31 formed by the connecting parts 33 of other layers. Figure 6 As shown), in the fifth embodiment, a larger hollowing is used to form a heat dissipation hole, and a heat dissipation groove is provided at the same time. The groove can quickly take away the heat inside and outside the connecting piece, and reliably dissipate heat for the outer ring and the bearing, thereby extending the service life of the product. The heat dissipation hole is larger, which is more conducive to air circulation and has a good heat dissipation effect. In addition, such a structure makes the connecting block in an "I" shape, which enhances the connection strength at the connecting block, reduces the overall volume and weight of the product, and reduces the production cost. At the same time, the connecting parts of different layers make the product strong and reduce the production cost. In addition, the projection of the connecting part is arranged in the heat dissipation hole formed by the connecting parts of other layers, so that the airflow can quickly take away the heat on the connecting part and the connecting piece when it flows through, thereby increasing the contact area. The drawings of the utility model provide a two-layer connecting part, but in fact, three or four layers or even more layers can be provided. Of course, in practice, it is also possible to use staggered connecting layers to form heat dissipation grooves and / or heat dissipation holes.

[0036] The heat dissipation part includes a heat dissipation groove 32, which is provided on two sides of the connector 3. Not shown in the figure, the heat dissipation groove can be in the form of a countersunk hole, and heat dissipation grooves are provided on both sides to increase the contact area of ​​the air. Another way is that the heat dissipation grooves on both sides of the connector can be partially connected.

[0037] The outer ring 1 is integrally formed of polyurethane, and the connector 3 is integrally formed of metal. The wear-resistant property of polyurethane is utilized to extend the service life of the product, and the heat dissipation is reliably performed through the heat dissipation part, which greatly extends the service life of the product. In the actual production process, the connector is usually made of metal such as iron or aluminum.
