Abstract

The invention provides a fully-closed pipeline sheet of an air jet loom, which comprises a pipeline sheet, wherein the pipeline sheet comprises an arc flaky supporting rod; two ends of the flaky supporting rod are fixed between an upper cross beam and a lower cross beam; an upper elastic sheet and a lower elastic sheet are arranged at the two ends of the flaky supporting rod respectively; magnets are arranged at the other ends of the upper elastic sheet and the lower elastic sheet, and are contacted on one side of the middle of the flaky supporting rod; a first arc elastic sheet and a second arc elastic sheet for being propped against the upper elastic sheet and the lower elastic sheet respectively are arranged in the middle of the flaky supporting rod; arc openings of the first arc elastic sheet and the second arc elastic sheet are opposite; warps passing through the pipeline sheet are interweaved to form a shed; magnetic guide rollers with the same magnetic poles as the magnets are arranged on the upper side and the lower side of the shed respectively. According to the invention, an open weft passage on the traditional pipeline sheet can be closed by the upper elastic sheet and the lower elastic sheet to enable airflow inside the weft passage to be less prone to diffusing, so that the picking is further and more precise.

Example Embodiment

[0017] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0018] refer to figure 1 , in this embodiment, the air-jet loom fully-enclosed pipe sheet includes a pipe sheet, and the pipe sheet includes an arc-shaped sheet-like strut 100, and the two ends of the sheet-like strut 100 are fixed on the upper beam 510 and the Between the lower crossbeams 520, the two ends of the sheet-like strut 100 are respectively provided with an upper elastic piece 210 and a lower elastic piece 220, and the other ends of the upper elastic piece 210 and the lower elastic piece 220 are provided with a magnet and are placed on the sheet-like strut. One side of the middle part of 100 is in contact with each other, and the middle part of the sheet-shaped support rod 100 is provided with a first arc-shaped elastic piece 310 and a second arc-shaped elastic piece 320 respectively resisting the upper elastic piece 210 and the lower elastic piece 220, the first The arc openings of the arc-shaped shrapnel 310 and the second arc-shaped shrapnel 320 are oppositely arranged, and the warp threads 21, 22 passing through the pipe sheet are interwoven into a shed, and the upper and lower sides of the shed are provided with magnetic poles with the same magnetic poles as the magnets. Guide rollers 410,420.

[0019] In the air-jet loom fully-enclosed pipe piece mentioned above, the contacting end surface of the upper elastic piece 210 and the lower elastic piece 220 is covered with a flexible material, and the flexible material can better seal the first arc-shaped elastic piece 310 and the second curved elastic piece 310. The weft channel surrounded by the arc-shaped shrapnel 320.

[0020] refer to image 3 , the magnetic guide rollers 410, 420 include bar magnets 411 arranged radially inside, the magnetic guide rollers 410, 420 are driven by a control motor, and the control motor drives the magnetic guide rollers 410, 420 to rotate, which can be controlled The orientation of the magnetic guide rollers 410, 420 relative to the magnetic poles of the magnets, see figure 1 , when the duct sheet is weft-picked, the repelling force of the magnetic guide rollers 410, 420 to the upper elastic piece 210 and the lower elastic piece 220 is reduced or the upper elastic piece 210 and the lower elastic piece 220 are attracted, see figure 2 , when the duct piece is beating up, the repulsive force of the magnetic guide rollers 410, 420 increases, so that the upper elastic piece 210 and the lower elastic piece 220 are separated and opened under the influence of the repulsive force.

[0021] In the air-jet loom fully-enclosed duct piece mentioned above, the middle parts of the first arc-shaped shrapnel 410 and the second arc-shaped shrapnel 420 are made of memory titanium. Due to the outstanding recovery of deformation performance of memory titanium, the entire structure is well improved. reliability.

[0022] The working mode of the above air-jet loom fully enclosed pipe piece:

[0023] refer to figure 1 , the weft channel surrounded by the first arc-shaped elastic piece 310 and the second arc-shaped elastic piece 320 is closed by the contacting upper elastic piece 210 and the lower elastic piece 220, see figure 1 , when the pipe sheet is weft picking, since the upper elastic piece 210 and the lower elastic piece 220 are far away from the magnetic guide rollers 410, 420, the magnetic guide rollers 410, 420 are aligned with the upper elastic piece 210 and the lower elastic piece 220 The repulsive force becomes smaller, and the upper elastic piece 210 and the lower elastic piece 220 are in a state of contact, refer to figure 2 , when the pipe sheet is beating up, the upper elastic piece 210 and the lower elastic piece 220 are close to the magnetic guide rollers 410, 420, and the repelling force of the magnetic guide rollers 410, 420 increases, so that the upper elastic piece 210 And the lower elastic sheet 220 is separated and opened under the influence of the repulsive force, and the weft thread 10 performs the beating-up operation.

[0024] The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. scope.
