Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of special-shaped reeds for looms, in particular to a special-shaped reed for a flat-weaving double-shaft loom. Background Art
[0002] A special-shaped reed for a flat weaving double-arrow loom is used to form the pile warp height of the supporting flat weaving double-arrow loom. The existing steel reeds are mainly of conventional 25-degree bending angle. When the pile warp length is determined in the form of a push needle, it will interfere with the push needle. All existing steel reeds on the market are not applicable. During weaving operation, the steel reed will collide with the push needle, making it difficult for the push needle to work normally, and eventually the woven cloth will be deformed or even the device will be damaged.
[0003] Based on this, a special-shaped reed for a flat weaving double-arrow loom is now provided, which can eliminate the disadvantage that the steel reed interferes with the pushing of the needle. Utility Model Content
[0004] The utility model aims to provide a special-shaped reed for a flat weaving double-shaft loom, so as to solve the problem that the push needle is difficult to work normally due to the collision of the steel reed.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A special-shaped reed for a flat-weaving double-arrow loom comprises a crossbeam, a fixed block is arranged at the other end of the crossbeam, a connecting block is arranged on the outer surface of the other end of the fixed block, a plurality of moving grooves are opened on the surface of the connecting block, a propulsion mechanism slides in the moving grooves, a push pin is arranged at the other end of the connecting block, and a limiting component is arranged on the surface of one end of the connecting block close to the push pin.
[0007] On the basis of the above technical solutions, the present invention also provides the following optional technical solutions:
[0008] In an optional solution: the propulsion mechanism includes a curved steel reed sliding in a moving groove, a first control block is provided at the lower end of the curved steel reed, a rotating shaft is fixedly connected between the first control blocks, a second control block is provided at the other end of the curved steel reed, and a connecting rod is provided between the second control blocks.
[0009] In an optional solution: the limiting component includes a hook fixed to one end of the connecting block, and the size of the hook matches the size of the curved reed.
[0010] In an optional solution: the outer surface of the curved reed is curved.
[0011] In an optional solution: the bending angle of the curved reed is 25°.
[0012] In an optional solution: a concave bend is provided in the middle of the curved reed.
[0013] In an optional solution: the reciprocating striking angle of the bent reed is less than 90°.
[0014] In an optional solution: height-fixing plates are provided on upper and lower surfaces of one end of the connection block close to the push pin.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] The utility model achieves the purpose of enabling the bent steel reed to avoid the push needle during the weaving operation by means of the concave bend on the surface of the bent steel reed. During the weaving process, the impact of the steel reed is very large, and a large impact force easily makes it difficult for the push needle to work. The concave bend can effectively protect the push needle, thereby increasing the service life of the device and increasing durability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Example 1
[0024] In one embodiment, Figure 1-Figure 4As shown, a special-shaped reed for a flat-woven double-arrow loom comprises a crossbeam 1, a fixed block 2 is arranged at the other end of the crossbeam 1, a connecting block 3 is arranged on the outer surface of the other end of the fixed block 2, a plurality of moving grooves 4 are opened on the surface of the connecting block 3, a propulsion mechanism 5 slides in the moving groove 4, a push pin 6 is arranged at the other end of the connecting block 3, a limiting component is arranged on the surface of one end of the connecting block 3 close to the push pin 6, and height-fixing plates 8 are arranged on the upper and lower surfaces of one end of the connecting block 3 close to the push pin 6 to limit the weaving angle during the manufacture of the flat-woven space cloth, prevent the warp and weft lines from being misaligned due to height mismatch during the weaving process, and ensure the quality of the finished textile products.
[0025] In one embodiment, Figure 2 and Figure 3 As shown, the propulsion mechanism 5 includes a curved steel reed 51 sliding in the moving groove 4, a first control block 52 is provided at the lower end of the curved steel reed 51, a rotating shaft 53 is fixedly connected between the first control blocks 52, a second control block 54 is provided at the other end of the curved steel reed 51, a connecting rod 55 is provided between the second control blocks 54, and a limiting component includes a hook 7 fixed to one end of the connecting block 3, the size of the hook 7 matches the size of the curved steel reed 51, the curved steel reed 51 rotates around the rotating shaft 53, and the surface of the curved steel reed 51 slides in the moving groove 4 at this time, and the pulled weft yarn is slapped toward the cloth outlet end to form a cloth surface with the warp yarn, and the hook 7 plays a role in limiting the reciprocating motion of the curved steel reed 51 to prevent the deformation of the woven cloth surface caused by excessive rotation and traction.
[0026] Example 2
[0027] The difference from Example 1 is that Figure 3 and Figure 4 As shown, the outer surface of the curved steel reed 51 is curved, the bending angle of the curved steel reed 51 is 25°, a concave bend 56 is provided in the middle of the curved steel reed 51, the reciprocating striking angle of the curved steel reed 51 is less than 90°, and the bending angle is designed to be 25° to ensure the stability of the interweaving of warp and weft yarns during the manufacturing process of the plain woven space cloth. During the weaving process, the curved steel reed 51 should frequently strike the weft yarn, and when it reaches an angle of 90 degrees, it cannot interfere with the operation of the push needle 6. The design of the curved bend further ensures that sufficient distance and position are reserved during normal weaving to ensure the smooth operation of the push needle 6.
[0028] The above embodiment discloses a special-shaped reed for a flat-woven double-arrow loom, in which the weaving angle during the manufacture of the flat-woven space cloth is limited to prevent the warp and weft lines from being misaligned due to height mismatch during the weaving process, thereby ensuring the quality of the finished textile product. The curved steel reed 51 rotates around the rotating shaft 53. At this time, the surface of the curved steel reed 51 slides in the moving groove 4, and the pulled weft yarn is slapped toward the cloth outlet end to form a cloth surface with the warp yarn. The hook 7 limits the reciprocating motion of the curved steel reed 51 to prevent excessive rotation and traction from causing deformation of the woven cloth surface. The bending angle is designed to be 25° to ensure the stability of the interweaving of the warp and weft yarns during the manufacture of the flat-woven space cloth. During the weaving process, the curved steel reed 51 needs to frequently slap the weft yarn. When it reaches an angle of 90 degrees, it cannot interfere with the operation of the push needle 6. The curved bending design further ensures that sufficient distance and position are reserved during normal weaving to ensure the smooth operation of the push needle 6.
