The parts not mentioned in the circular knitting machine are all in the prior art, and are not described in detail herein.

The utility model is that the top of the memorial arch 200 is fixedly connected with the foundation of the top ring 400, the memorial arch 200, the top ring 400 and the upper door ring 600 are fixedly connected with the top of the top ring 400 or the memorial arch 200 through the upper door ring 600, so that the memorial arch 200, the top ring 400 and the upper door ring 600 are integrally formed, the vibration generated by the shuttle motion of the upper door ring 600 can be transmitted to the memorial arch 200, and the bottom of the memorial arch 200 is fixedly connected with the chassis 100, therefore, a part of vibration can be transmitted to the chassis 100, and the energy of a part of vibration is consumed in the long-distance transmission process; secondly, the top ring 400 is designed to comprise a first ring body 401 extending radially and a second ring body 402 extending axially, the top end of the second ring body 402 is connected with the inner ring of the first ring body 401 into a whole, proper sizes are selected for B1 and H, the large size of the second ring body 402 in the axial direction is utilized to obtain higher structural strength, vibration can be uniformly dispersed through the circular ring structure of the second ring body 402, the inner ring of the first ring body 401 is not easy to deform, the thickness B1 of the first ring body 401 is utilized to obtain higher structural strength in the radial direction, therefore, the outer ring of the first ring body 401 is not easy to deform, at the moment, the upper roller 701 is hoisted on the first ring body 401, the stability of the upper roller 701 can be ensured, the condition that the upper roller and the lower roller jump are difficult to occur is ensured, the heald belt 700 is tensioned by the upper roller 701, and the knitting quality is guaranteed. B1 is also not too large, typically not more than 30mm, in view of cost.

The radial thickness of the second ring body 402 is B2, so that the second ring body 402 has enough strength in the radial direction, the influence of centrifugal force generated by the circular motion of the shuttle on the upper roller 701 can be reduced, B2 which is less than or equal to 8mm and less than or equal to 16mm, for example, B2=12 mm, can be reasonably selected, and B2 which is less than or equal to B1 can be simultaneously selected in order to save the material consumption and reduce the weight of the top ring after the enough strength is obtained.

Referring specifically to fig. 3, the upper roller 701 is mounted on the upper bracket 702, the radius of the upper roller 701 is R1, the upper bracket 702 is connected with the first ring body 401 through the connecting piece 703, the first ring body 401 is provided with a mounting through hole 403 for the connecting piece 703 to pass through, and the distance from the center of the mounting through hole 403 to the peripheral side surface of the first ring body 401 is L1, where R1 is less than or equal to L1 and less than or equal to 25mm. Firstly, L1 is larger than R1, so as to reduce the probability of dust falling onto the upper roller 701 when the dust falls under gravity, and secondly, L1 is not more than 25mm, for example, l1=16mm, so as to ensure that the upper roller 701 is not far away from the second ring 402, and the upper roller 701 is hoisted at a position with higher structural stability of the first ring 401. For a specific installation of the upper roller 701, reference is made to the prior art CN219032507U, which is not developed here.

The radial distance from the upper bracket 702 to the second ring body 402 is L2, and since the strength of the first ring body 401 from outside to inside is gradually increased, the closer the upper roller 701 is lifted to the second ring body 402, the better the anti-seismic effect is, and thus, 1mm < L2 < 5mm, for example, l2=3 mm, etc. can be selected.

In order to make the top ring 400 obtain a better supporting effect of the housing 200, the top end surface of the housing 200 can be abutted against the bottom surface of the first ring body 401, the inner side surface of the housing 200 can be abutted against the outer side surface of the second ring body 402, and the housing 200 can bear axial and radial vibration.

In the prior art, since the top ring 400 is formed by processing steel materials, the weight is large, in order to fix the top ring 400 above the upper door ring 600, the scheme of fixedly connecting the upper door ring 600 and the top ring 400 by adopting the supporting rods 800 is adopted, specifically, the supporting rods 800 are connected between the top ring 400 and the upper door ring 600, the number of the supporting rods 800 is more, generally 12 to 16, and because the top ends of the supporting rods 800 are connected, drilling processing is required on the top ring 400, the requirement on the accuracy of the drilling processing position of the top ring 400 is higher in order to ensure that the supporting rods 800 are uniformly stressed, the production cost is increased, and the installation time is wasted because the number is too much.

As seen in conjunction with fig. 4 and 5, therefore, in order to reduce the number of the support bars 800, the support bars 800 include an upper connection portion 801 and at least two lower connection portions 802, the upper connection portion 801 is fixedly connected with the top ring 400, the upper end of the lower connection portion 802 is connected with the lower end of the upper connection portion 801, the lower end of the lower connection portion 802 is fixedly connected with the upper door ring 600, and the number of the support bars 800 is not more than 10. The support rods 800 are designed to have a structure comprising at least two lower connecting portions 802, each support rod 800 is fixedly connected with the upper door ring 600 by at least two lower connecting portions 802, which is equivalent to providing at least two points of force, so that all the support rods 800 can provide at least twice as many points of force as the support rods 800, vibration generated by shuttle motion is more uniformly distributed on the support rods 800, and therefore, under the condition that the number of the support rods 800 is not more than 10, the fixed connection between the top ring 400 and the upper door ring 600 can be realized, the structural stability of the upper door ring 600 is improved, the stable shuttle motion is facilitated, the number of the support rods 800 is effectively reduced, the production cost is reduced, and the assembly efficiency is improved.

In one embodiment, the lower connecting portion 802 is provided with two connecting portions 801 extending to two sides opposite to each other to form a Λ -shaped structure, and the two lower connecting portions 802 are fixedly connected with the upper door ring 600 to form a triangular structure, so that the structural stability is better. It will be appreciated that the two lower connection portions 802 may be formed in other common shapes such as a n-shaped structure or a n-shaped structure, where structural strength is satisfactory.

Because the circular knitting machine can generate larger vibration in the working process, under the premise of reducing the number of the supporting rods 800, in order to further improve the connection stability of the supporting rods 800 to the top ring 400 and the upper door ring 600, the lower end of the lower connecting part 802 can be designed to be close to the center of the upper door ring 600 relative to the upper end of the lower connecting part 802, and all the supporting rods 800 can form an annular inclined pulling effect so as to offset the vibration generated in the working process of the circular knitting machine, thereby reducing the influence of the vibration and improving the structural stability of the top ring 400 and the upper door ring 600.

For the convenience of the installation connection of the lower connection part 802 and the upper door ring 600, the connection pin 803 can be arranged at the bottom end of the lower connection part 802, the lower connection part 802 is fixedly connected with the upper door ring 600 through the connection pin 803, the connection pin 803 extends from outside to inside relative to the upper door ring 600, the connection pin 803 can be changed into a state in which a worker can stand and see, the connection pin 803 is installed without adopting the mode of bending down, squatting down and the like to change the body posture, the labor is saved, and the assembly efficiency is further improved.

In one embodiment, the support bar 800 may be provided with 6 or 8 support bars. In a smaller circular loom, a smaller number of 5 or 4 support rods 800 may be selected, and generally not less than 3 support rods are provided. It is understood that 7, 8, 9 or 10 support bars 800 may be provided for the number of support bars 800 to improve the support stability, for example, 8 support bars 800 are provided in fig. 5.

In order to allow the support bar 800 to uniformly distribute the force, the support bar 800 may be selected to be uniformly distributed in the circumferential direction of the top ring 400.

In the above embodiment, only one upper connection portion 801 is provided, so that the number of holes to be drilled on the top ring 400 is greatly reduced, and the assembly efficiency is very high. In some cases, two upper connection portions 801 are provided, and the support bar 800 is in an X-shape or H-shape, etc., so that the assembly efficiency can be improved, but the effect is not significant enough, so that it is not recommended to excessively increase the number of upper connection portions 801. In order to increase the supporting effect of the supporting bar 800, more lower connection portions 802 may be provided, and after the number of lower connection portions 802 is increased, the effect of improving the assembly efficiency is gradually reduced, so that it is not suggested to excessively increase the number of lower connection portions 802.

Specifically, the upper connection portion 801 may be fixedly connected to the second ring body 402, for example, an inner side surface of the second ring body 402, referring to fig. 4, so as to facilitate observation and assembly by a worker. Of course, may be attached to the outer side of the second ring body 402, as shown in fig. 5. Nor does it exclude that the upper connection 801 is fixedly connected to the first ring body 401.

In another embodiment, the upper connection portion 801 may be fixedly connected to the inner side surface of the housing 200, for example, as shown in fig. 2 and 3, the vibration of the upper door ring is directly transferred to the housing 200 by using the support rods 800, so as to reduce the influence on the top ring 400, and the number of the support rods 800 is equal to the number of the housing 200, for example, in a four-shuttle or eight-shuttle circular loom, the number of the housing 200 is generally 8, and in a six-shuttle circular loom, the number of the housing 200 is generally 6.

In addition to the preferred embodiments described above, other embodiments of the present utility model are also contemplated as falling within the scope of the claimed utility model, as well as all other embodiments that may be made by one of ordinary skill in the art without making any inventive effort based on the embodiments of the present utility model.
