Description

Technical Field

[0001] The utility model relates to the technical field of plastic weaving, in particular to a circular loom. Background Art

[0002] In the existing plastic circular loom, in order to realize the suspended operation of the shuttle, that is, the shuttle does not contact the lower surface of the upper door ring and the upper surface of the lower door ring during operation, the lower surface of the upper door ring and the upper surface of the lower door ring are both set to be planes, the door ring assembly is set around the size ring, the shuttle is slidably installed between the upper door ring and the lower door ring, and the shuttle cooperates with the size ring through the shuttle arm.

[0003] For example, the structure of the door ring assembly is disclosed in Chinese patent Nos. CN201811023233.8 and CN201810035693.6. The door ring assembly is located on the inner side of the shuttle running track and no limiting structure is set. When static, the shuttle is loosely installed in the track. The smaller the size ring is, the longer the shuttle arm is extended, and the more unstable it is. Once the warp and weft are broken, it will cause the flying shuttle phenomenon. When the shuttle body loses or reduces the outward centrifugal force when it stops slowly, the shuttle body will shift inward, and the entanglement of the warp and weft will forcefully pull the shuttle body out and cause the flying shuttle.

[0007] As a preferred technical solution of the utility model, the shuttle also includes a shuttle wheel, which is rotatably installed on the upper and lower sides of the shuttle. When the shuttle rotates along the door ring assembly, the shuttle wheel is always limited to the inner side of the annular flange or a plurality of blocking members.

[0008] As a preferred technical solution of the present utility model, a wheel groove for installing a shuttle wheel is provided on one side of the shuttle facing away from the roller assembly or the roller. There is a gap between the shuttle wheel and the annular flange or the blocking member. When the outside of the shuttle disengages from the rolling track, the shuttle wheel directly contacts the annular flange or the blocking member.

[0009] As a preferred technical solution of the present utility model, the lower surface of the upper door ring and the upper surface of the lower door ring are radial planes.

[0010] As a preferred technical solution of the present utility model, the lower surface of the upper door ring includes an upper flat runway for the shuttle wheel to roll on and an ascending step surface for installing the upper end of the roller assembly or the roller; the upper surface of the lower door ring includes a lower flat runway for the shuttle wheel to roll on and a descending step surface for installing the lower end of the roller assembly or the roller.

[0011] As a preferred technical solution of the present utility model, the annular flange is integrally formed on the inner ring side of the upper door ring or the lower door ring.

[0015] In summary, the beneficial effects of the present utility model are as follows: By providing an annular flange or arranging a plurality of blocking members at intervals, the shuttle can be prevented from being thrown out or pulled out, thus avoiding the phenomenon of flying shuttle. Since the shuttle is loosely installed in the door ring assembly, during normal weaving, the outer side of the shuttle contacts the rolling track, so the shuttle wheel will not contact the annular flange or several blocking members, which can prevent wear on the inner side of the annular flange or several blocking members, and the shuttle runs more smoothly. Once the phenomenon of broken warp or weft occurs, when the machine stops and runs slowly and the outward centrifugal force of the shuttle body is lost or reduced, the shuttle wheel contacts the inner side of the annular flange or several blocking members, and will not be pulled out, thus avoiding the phenomenon of flying shuttle.

Detailed Embodiment

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model.

[0028] The following describes the specific embodiments of the present utility model with reference to the drawings.

[0029] As Figures 1 to 10 shown, a circular loom includes a door ring assembly 1 and a shuttle 2 located on a frame. The door ring assembly 1 includes an upper door ring 3 and a lower door ring 4. A roller assembly 5 or rollers (not shown in the figure) are arranged between the upper door ring 3 and the lower door ring 4. A plurality of roller assemblies 5 or a plurality of rollers are arranged along the circumferential direction of the door ring assembly 1. The plurality of roller assemblies 5 or the plurality of rollers form a rolling track for the shuttle 2 to run. The shuttle 2 is longitudinally limited between the upper door ring 3 and the lower door ring 4, and the outer side of the shuttle 2 corresponds to the rolling track. An annular flange 6 or a plurality of blocking members 7 are arranged on the inner - circle side of the running track of the shuttle 2 on the upper door ring 3 or the lower door ring 4. The annular flange 6 or the plurality of blocking members 7 are used to limit the shuttle 2 from disengaging from the door ring assembly 1 when rotating.

[0030] When the door ring assembly 1 is provided with the structure of the annular flange 6, in this embodiment, only the upper door ring 3 can be provided with the annular flange 6, or only the lower door ring 4 can be provided with the annular flange 6, or both the upper door ring 3 and the lower door ring 4 can be provided with the annular flange 6 at the same time; when the door ring assembly 1 is provided with the structure of a plurality of blocking members 7, in this embodiment, only the upper door ring 3 can be provided with a plurality of blocking members 7, or only the lower door ring 4 can be provided with a plurality of blocking members 7, or both the upper door ring 3 and the lower door ring 4 can be provided with a plurality of blocking members 7 at the same time.

[0031] By setting an annular flange 6 or setting multiple blocking members 7 at intervals, the shuttle 2 can be prevented from being pulled out and causing the flying shuttle phenomenon. Since the shuttle 2 is loosely installed in the door ring assembly 1, during normal weaving, the outer side of the shuttle 2 contacts the rolling track, so the shuttle wheel 8 will not contact the annular flange 6 or several blocking members 7, which can avoid wear on the inner side of the annular flange 6 or several blocking members 7, and the shuttle 2 can run more smoothly. Once the warp and weft threads are broken, the shuttle body loses or reduces the outward centrifugal force when it stops slowly, and the shuttle wheel 8 contacts the inner side of the annular flange 6 or several blocking members 7, and will not be pulled out, thereby avoiding the flying shuttle phenomenon.

[0032] A notch 26 is provided on the annular flange 6, which is adapted to the shape of the shuttle 2 so that it can enter the door ring assembly 1; or, among the multiple blocking members 7 arranged at intervals, at least one of the adjacent two blocking members 7 forms an installation channel 27 for the shuttle to enter the door ring assembly 1, and the spacing between the remaining blocking members 7 is smaller than that of the shuttle 2. In this way, there is no need to disassemble, and both schemes can be directly installed from the notch 26 or the installation channel 27. Even if there is a notch 26 or an installation channel 27, the flying shuttle phenomenon can be solved, and the probability of the shuttle 2 being thrown out of the notch 26 / installation channel 27 is very low and can be almost ignored.

[0033] The shuttle 2 also includes a shuttle wheel 8, which is rotatably installed on the upper and lower sides of the shuttle 2. When the shuttle 2 rotates along the door ring assembly 1, the shuttle wheel 8 is always limited to the inner side of the annular flange 6 or a plurality of blocking members 7. A wheel groove 9 for installing the shuttle wheel 8 is provided on the side of the shuttle 2 facing away from the drum assembly 5 or the roller. There is a gap between the shuttle wheel 8 and the annular flange 6 or the blocking member 7. When the outer side of the shuttle 2 leaves the rolling track, the shuttle wheel 8 directly contacts the annular flange 6 or the blocking member 7.

[0034] like Figure 2 As shown, the lower surface of the upper door ring 3 and the upper surface of the lower door ring 4 are radial planes 10. Alternatively, in another case, as Figure 3 , 4 As shown, the lower surface of the upper door ring 3 includes an upper plane runway 11 for the shuttle wheel 8 to roll and a rising step surface 12 for the upper end of the roller assembly 5 or the roller to be installed; the upper surface of the lower door ring 4 includes a lower plane runway 13 for the shuttle wheel 8 to roll and a sinking step surface 14 for the lower end of the roller assembly 5 or the roller to be installed.

[0035] The annular flange 6 is integrally formed on the inner ring side of the upper door ring 3 or the lower door ring 4. The inner connection between the annular flange 6 and the upper door ring 3 or the lower door ring 4 is transitioned through a rounded corner 15 and the rounded corner 15 is adapted to the shuttle wheel 8. The function of the annular flange 6 is to limit the shuttle wheel 8 on the shuttle 2. The rounded corner 15 of the shuttle wheel 8 is similar to the annular convex rounded corner 15, and the shuttle wheel 8 will not get stuck when rolling in contact with the flange.

[0036] like Figure 7As shown, the blocking member 7 is an arc-shaped baffle integrally formed on the inner ring side of the upper door ring 3 or the lower door ring 4. This is an extended solution. The connection between the arc-shaped baffle and the inner side of the upper door ring 3 or the lower door ring 4 is transitioned through a fillet 15 (not shown in the figure) and the fillet 15 is adapted to the arc surface of the shuttle wheel 8. A plurality of arc-shaped baffles are provided and are evenly distributed along the circumferential direction. The function of the arc-shaped baffle is to limit the shuttle wheel 8 on the shuttle 2. The fillet 15 of the shuttle wheel 8 is similar to the inner fillet 15 of the arc-shaped baffle. The shuttle wheel 8 will not get stuck when rolling in contact with the arc-shaped baffle. The distance between two adjacent arc-shaped baffles is less than 1 / 2 of the length of the shuttle 2, and is not limited to this width. The gap is controlled according to actual conditions. It is necessary to ensure that the shuttle 2 will not separate from the door ring assembly 1 during operation, and the shuttle wheel 8 will not deviate.

[0037] It also includes a size ring 16 arranged on the frame and located at the center of the door ring assembly 1, and a circular track 17 is directly or indirectly formed on the outer periphery of the size ring 16. A triangular shuttle arm 18 for installing the shuttle 2 is arranged between the door ring assembly 1 and the size ring 16, and the inner end of the triangular shuttle arm 18 has a guide wheel 19 that rotates along the path of the circular track 17. In this embodiment, anti-slip inclined surfaces 20 or anti-slip arc surfaces are arranged on the upper and lower sides of the circular track 17.

[0038] It also includes a core shaft 21 for fixing the roller assembly 5, and the two ends of the core shaft 21 are respectively connected to the upper door ring 3 and the lower door ring 4. The core shaft 21 is provided with at least one group of roller assemblies 5, and the roller assembly 5 includes an upper dust cover 22, a lower dust cover 23, a rotating member 24 and a rubber ring 25. The rotating member 24 is sleeved on the outside of the core shaft 21, and the rotating member is a hollow roller or a bearing. The rubber ring 25 is sleeved on the outside of the rotating member 24. The upper dust cover 22 is located above the rotating member 24 and is positioned on the upper door ring 3. The lower dust cover 23 is located below the rotating member 24 and is positioned on the lower door ring 4. The upper dust cover 22 and the lower dust cover 23 will The rotating member 24 is axially positioned, the outer diameter of the upper dust cover 22 is equal to the outer diameter of the rotating member 24, and the outer diameter of the lower dust cover 23 is equal to the outer diameter of the rotating member 24; when the roller (not shown in the figure) is adopted, the upper and lower ends of the roller are rotatably installed on the upper door ring 3 and the lower door ring 4, and a rubber ring 25 can be set on the outer side of the roller; if only one set of roller assemblies 5 is set on a core shaft 21, it is necessary to ensure that the length of the roller assembly 5 is equal to the length between the upper door ring 3 and the lower door ring 4; if multiple sets of roller assemblies 5 are set, the length of the multiple sets of roller assemblies 5 after stacking is equal to the distance between the upper door ring 3 and the lower door ring 4, such as Figure 2 As shown, in this embodiment, two groups are preferably set.
