Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to a leniency device for air jet looms. Background Art

[0002] The conventional assembly process of the hemming shaft is to use impact force to clamp the flat key at both ends of the hemming shaft. The power required for hemming is transmitted by the hemming shaft, so the assembly of the flat key that transmits power on the hemming shaft is particularly critical.

[0003] According to a disclosed air jet loom hemming shaft (publication number: CN216378592U), a support assembly is added in the above application. When the slider slides in the slide groove, the roller is compressed and shrinks inward under the action of the support spring. When the roller is located at the position of the clamping groove, the roller pops out under the action of the support spring, thereby forming a clamping connection. When the hemming shaft is rotating, it is more stable, and if it is replaced, it can be quickly replaced by pulling the first sliding sleeve, the second sliding sleeve and the third sliding sleeve with force, and the structure is simple. However, the device cannot fix the position of the roller during use, and the hemming shaft is easy to fall off during rotation; in view of this, we propose a hemming device for air jet looms.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a selvedge device for an air jet loom, comprising a selvedge shaft body 1, sleeves 2 are arranged on both sides of the selvedge shaft body 1, and the selvedge shaft body 1 is installed by pushing the sleeve 2 into the inside of the selvedge shaft body 1, a limiting groove 3 is provided on the inner wall of the selvedge shaft body 1, an installation groove 4 is provided on the sleeve 2, and an installation mechanism 5 is arranged inside the installation groove 4.

[0023] In this embodiment, an installation mechanism 5 is provided inside the installation groove 4. The roller 53 in the installation mechanism 5 is squeezed by the hemming shaft body 1, so that the roller 53 can drive the squeezing rod 51 to move into the inside of the installation groove 4 to release the limit, and then the elastic force of the supporting spring 52 is used to make the squeezing rod 51 drive the roller 53 to move into the inside of the limit groove 3 to facilitate the installation. At the same time, the slider 55 generates centrifugal force during the rotation process, which can make the slider 55 move in the direction of the bent plate 58 to squeeze one end of the bent plate 58, so that the limit rod 59 can be engaged with the inside of the slot 510, so that the position of the roller 53 can be fixed to prevent unstable installation.

[0024] The above-mentioned installation mechanism 5 includes an extrusion rod 51, which passes through the interior of the installation groove 4. A load-bearing spring 52 is sleeved on the outer wall of the extrusion rod 51, one end of the load-bearing spring 52 is fixedly connected to the inner wall of the installation groove 4, and the other end of the load-bearing spring 52 is fixedly connected to the outer wall of the extrusion rod 51. The elastic force of the load-bearing spring 52 can make the extrusion rod 51 drive the roller 53 to move into the interior of the limiting groove 3 to complete the installation. The end of the extrusion rod 51 is rotatably connected with the roller 53, and the roller 53 is partially located outside the installation groove 4. The roller 53 is squeezed by the hemming shaft body 1, so that the roller 53 can drive the extrusion rod 51 to move into the interior of the installation groove 4, which is convenient for installation. The inner wall of the installation groove 4 is fixedly connected to one end of the tension spring 54, and the other end of the tension spring 54 is fixedly connected to the slider 55. The body 1 drives the internal slider 55 to rotate to generate centrifugal force, which can make the slider 55 move in the direction of the bent plate 58 to squeeze one end of the bent plate 58. The slider 55 is slidably connected to the inner wall of the mounting groove 4, and a rotating rod 56 is rotatably connected to the inner wall of the mounting groove 4. The inner wall of the mounting groove 4 is fixedly penetrated by the bent plate 58, and a limiting rod 59 is fixedly installed on the outer wall of the bent plate 58. The limiting rod 59 is driven by the bent plate 58 to be engaged with the inside of the slot 510, so that the position of the roller 53 can be fixed to prevent the roller 53 from moving out of the limiting groove 3 during use of the device, resulting in unstable installation. The outer wall of the rotating rod 56 is fixedly connected to one end of the torsion spring 57, and the other end of the torsion spring 57 is elastically connected to the inner wall of the mounting groove 4. The roller 53 is provided with a slot 510, and the slots 510 are distributed in a circular array on the roller 53.

[0025] In this embodiment, during installation, the sliding sleeve 2 is pushed toward the inside of the hemming shaft body 1, and then the sliding sleeve 2 drives the roller 53 at the end of the extrusion rod 51 to move toward the hemming shaft body 1, and then the hemming shaft body 1 squeezes the roller 53, so that the roller 53 drives the extrusion rod 51 to move toward the inside of the installation groove 4, and then the elastic force of the bearing spring 52 is used to drive the extrusion rod 51 to move into the inside of the limit groove 3 to complete the installation. During use, the hemming shaft body 1 drives the internal slider 55 to rotate to generate centrifugal force, so that the slider 55 The roller 53 is moved in the direction of the bent plate 58, and then one end of the bent plate 58 is squeezed by the slider 55 to rotate the bent plate 58, and finally the limit rod 59 is driven by the other end of the bent plate 58 to engage into the interior of the slot 510, so that the position of the roller 53 is fixed, and the roller 53 is prevented from moving out of the limit slot 3 during use of the device, resulting in unstable installation. When the device stops being used, the elastic force of the tension spring 54 can reset the slider 55, and then the limit rod 59 is moved out of the interior of the slot 510 to release the limit, so as to facilitate disassembly.
