Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air jet looms, in particular to a yarn clamp for air jet looms. Background Art
[0002] The air jet loom is a shuttleless loom that uses a jet airflow to pull the weft yarn through the shed. A yarn clamp is generally installed on the air jet loom to constrain the yarn.
[0003] However, after the existing yarn clamp is installed on the air-jet loom, when the yarn is located between the two clamping plates of the yarn clamp and is too close to the inner circle, the yarn will be rubbed by the stud and is more likely to break. When it is too close to the outer circle, the yarn will break away from the two clamping plates of the yarn clamp due to some vibration, causing the yarn to come off. Moreover, when the yarn tension suddenly increases, the yarn is prone to breakage. Utility Model Content
[0004] The utility model provides a yarn clamp for an air jet loom to solve the above technical deficiencies, which can prevent the yarn from being easily derailed and broken.
[0005] The utility model discloses a yarn clamp for an air jet loom, comprising a vertical mounting plate, a stud is horizontally arranged on the side of the mounting plate, two chucks are sleeved on the middle of the stud, nuts are arranged on the ends of the stud, thrust bearings and springs are sleeved on the studs between the chucks and the mounting plate and on the studs between the chucks and the nuts, the thrust bearings are abutted against the chucks, the springs are in a compressed state, yarn guide rings are arranged on the incoming material side and the feeding material side of the upper middle parts of the two chucks, and the yarn guide rings are connected to the mounting plate through a brittle connecting rod.
[0006] When the above technical solution is in use, the mounting plate is installed on the lower side of the air jet loom, and the yarn is led downward from the yarn rack on the upper side of the air jet loom, passes through the yarn guide ring on the incoming side of the chuck, the chuck and the yarn guide ring on the feeding side of the chuck in turn, and then is led upward into the air jet loom. The yarn is restricted between the chucks by the yarn guide ring, so that the yarn is not easy to fall off the chucks. When the yarn is transported, due to the setting of the thrust bearing, the chuck will rotate, and sliding friction will occur between the chuck and the yarn. The clamping force between the two chucks is adjusted by the nut, thereby adjusting the friction between the yarn and the chuck. When the yarn tension suddenly increases, the chuck rotates faster to prevent the yarn from breaking. If the tension mutation is large, the brittle connecting rod will break directly, and the yarn will fall off directly from the chuck to prevent the yarn from breaking.
[0007] Furthermore, in order to better control the breaking position of the brittle connecting rod, a groove is provided on the brittle connecting rod along the circumference, and when breaking occurs, the fracture point is located at the groove.
[0008] Furthermore, in order to break the fragile connecting rod with a smaller force, the groove is arranged at the end of the fragile connecting rod away from the yarn guide ring.
[0009] The utility model provides a jet loom yarn clamp, which has the beneficial effect of limiting the yarn between the chucks through the yarn guide ring, so that the yarn is not easy to fall off from the chuck during normal transportation, when the yarn tension suddenly increases, the chuck rotates faster to prevent the yarn from breaking, if the tension mutation is large, the brittle connecting rod breaks directly, and the yarn falls off directly from the chuck to prevent the yarn from breaking.

[0011] Figure 2 This is a schematic diagram of the structure of Example 1 of the utility model. DETAILED DESCRIPTION
[0012] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0013] Embodiment 1:
[0014] like Figure 1 , 2 As shown, the utility model discloses a yarn clamp for an air jet loom, comprising a vertical mounting plate 1, a stud 8 is horizontally arranged on the side of the mounting plate 1, two chucks 5 are sleeved on the middle part of the stud 8, a nut 7 is arranged on the end of the stud 8, a thrust bearing 6 and a spring 9 are sleeved on the stud 8 between the chuck 5 and the mounting plate 1 and on the stud 8 between the chuck 5 and the nut 7, the thrust bearing 6 is abutted against the chuck 5, the spring 9 is in a compressed state, a yarn guide ring 4 is arranged on the incoming material side and the feeding material side of the upper middle part of the two chucks 5, and the yarn guide ring 4 is connected to the mounting plate 1 through a brittle connecting rod 3.
[0015] When the above technical scheme is in use, the mounting plate 1 is installed on the lower side of the air jet loom, and the yarn is led downward from the yarn frame on the upper side of the air jet loom, passes through the yarn guide ring 4 on the incoming side of the chuck 5, the chuck 5 and the yarn guide ring 4 on the feeding side of the chuck 5 in turn, and then is led upward into the air jet loom. The yarn is restricted between the chucks 5 by the yarn guide ring 4, so that the yarn is not easy to fall off from the chuck 5. When the yarn is transported, due to the setting of the thrust bearing 6, the chuck 5 will rotate, and sliding friction will occur between the chuck 5 and the yarn. The clamping force between the two chucks 5 is adjusted by the nut 7, thereby adjusting the friction between the yarn and the chuck 5. When the yarn tension suddenly increases, the chuck 5 rotates faster to prevent the yarn from breaking. If the tension mutation is large, the brittle connecting rod 3 breaks directly, and the yarn falls directly off from the chuck 5 to prevent the yarn from breaking.
[0016] In order to better control the breaking position of the brittle connecting rod 3 , a groove 2 is provided on the brittle connecting rod 3 along the circumferential direction. When breaking occurs, the fracture point is located at the groove 2 .
[0017] In order to break the fragile connecting rod 3 with a smaller force, the groove 2 is arranged at the end of the fragile connecting rod 3 away from the yarn guide ring 4.
