A kind of cloth tenter device
[technical field]
This utility model relates to the technical field of fabric process equipment, particularly a kind of cloth tenter device.
[background technology]
Cloth needs it is carried out tentering before dyeing, make it launch, owing to cloth realizes the conveying of distance under the traction of conveying roller, there will be gauffer, after repeatedly rolling, gauffer is difficult to eliminate, and in follow-up dyeing and finishing technology, fold place can produce trace, highly impacts the quality of fabric.Prior art is processed by tentering and eliminates gauffer.Existing tenter device includes roll shaft, and the surface of described roll shaft is flank, and described flank is divided into four districts, and the hand of spiral of adjacent Liang Ge district flank is contrary.When cloth moves along the surface of roll shaft and band action roller shaft do low-angle rotation, owing to roll shaft is driven, such cloth is more serious at the surface abrasion of roll shaft, and it arranges comparatively in disorder after carrying out tentering in entering into collecting cart, easily fold occurs again, needing operator that cloth is rearranged, the labor intensity of operator is big, and production efficiency is low.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, it is proposed to a kind of cloth tenter device, it is possible to reduces design on fabric surface abrasion, and reaches mechanical type arrangement, it is to avoid fold produces again, improves working (machining) efficiency.
For achieving the above object, the utility model proposes a kind of cloth tenter device, including frame, it is arranged on the upper cloth rewinder roll of frame top, the drive roll being connected with step motor drive and untwisting rod, described untwisting rod is positioned at below cloth rewinder roll, the diameter of described untwisting rod is gradually reduced to two ends by centre, it is provided with driven transition roller between described untwisting rod and drive roll, described driven transition roller is provided with the velocity sensor being connected with described motor, the side, lower section of described drive roll is provided with mean for the swing span that cloth passes through and reciprocally swings, the collecting cart for collecting cloth it is provided with bottom described swing span.
As preferably, described untwisting is excellent and is provided with secondary between driven transition roller flattens frame, and described secondary flattens in frame and is provided with mean for the gap that cloth passes through.
As preferably, described swing span and described frame pin joint, swing span is connected with pull lever, described pull lever is connected with by the moving block of oscillating motor eccentric drive.
As preferably, described swing span being sequentially provided with the first flattening bar and second and flattens bar, it is protruding in arc-shaped through bending that the first flattening bar and second flattens bar, and the protrusion direction that described first flattening bar and second flattens bar is contrary.
As preferably, described swing span top is provided with once fabric guide roll.
The beneficial effects of the utility model: this utility model utilizes the upper cloth rewinder roll of frame top to be introduced from eminence by cloth, cloth is launched through untwisting rod, velocity sensor sensing cloth transmission speed, and electric impulse signal is conveyed to motor by its adjustment untwisting rod speed, keep consistent with the transmission speed of cloth, make fabric that fold be less likely to occur, abrasion, cloth is neatly stacked to collecting cart by the swing span simultaneously utilizing reciprocally swinging, compared with prior art, this utility model reduces design on fabric surface abrasion, reach mechanical type arrangement, avoid fold again to produce, improve working (machining) efficiency.
Feature of the present utility model and advantage will be described in detail in conjunction with accompanying drawing by embodiment.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of untwisting rod in this utility model;
Fig. 3 is the structural representation that in this utility model, the first flattening bar and second flattens bar;
In figure: the upper cloth rewinder roll of 1-frame, 2-, 3-motor, 4-drive roll, 5-untwisting rod, the driven transition roller of 6-, 7-velocity sensor, 8-swing span, 9-collecting cart, 10-bis-times flatten frame, 11-pull lever, 12-oscillating motor, 13-moving blocks, 14-first flattens bar, 15-second flattens bar, 16-fabric guide roll.
[detailed description of the invention]
Consult Fig. 1, Fig. 2 and Fig. 3, this utility model includes frame 1, it is arranged on the upper cloth rewinder roll 2 at frame 1 top, the drive roll 4 and untwisting rod 5 that are connected is driven with motor 3, described untwisting rod 5 is positioned at below cloth rewinder roll 2, the diameter of described untwisting rod 5 is gradually reduced to two ends by centre, it is provided with driven transition roller 6 between described untwisting rod 5 and drive roll 4, described driven transition roller 6 is provided with the velocity sensor 7 being connected with described motor 3, the side, lower section of described drive roll 4 is provided with mean for the swing span 8 that cloth passes through and reciprocally swings, the collecting cart 9 for collecting cloth it is provided with bottom described swing span 8.After adopting such scheme, this utility model utilizes the upper cloth rewinder roll 2 at frame 1 top to be introduced from eminence by cloth, cloth is launched through untwisting rod 5, velocity sensor 7 senses cloth transmission speed, and electric impulse signal is conveyed to motor 3 by its adjustment untwisting rod 5 speed, keep consistent with the transmission speed of cloth, make fabric that fold be less likely to occur, abrasion, cloth is neatly stacked to collecting cart 9 by the swing span 8 simultaneously utilizing reciprocally swinging, compared with prior art, this utility model reduces design on fabric surface abrasion, reach mechanical type arrangement, avoid fold again to produce, improve working (machining) efficiency.
Concrete, it being provided with secondary between described untwisting rod 5 and driven transition roller 6 and flatten frame 10, described secondary flattens in frame 10 and is provided with mean for the gap that cloth passes through.Utilize secondary to flatten frame 10 and can be further ensured that flattening effect.
Concrete, described swing span 8 and described frame 1 pin joint, swing span 8 is connected with pull lever 11, described pull lever 11 is connected with by the moving block 13 of oscillating motor 12 eccentric drive.Swing span 8 is thus driven to do oscillating traverse motion.
Concrete, described swing span 8 is sequentially provided with the first flattening bar 14 and second and flattens bar 15, first flattening bar 14 and the second flattening bar 15 are protruding in arc-shaped through bending, and the protrusion direction of described first flattening bar 14 and the second flattening bar 15 is contrary, and described swing span 8 end is provided with a pair fabric guide roll 16.Cloth follows swing span 8 when doing reciprocally swinging, cloth can be played a supportive role by the first flattening bar 14 and the second flattening bar 15, avoid its recurrence fold, carry out mechanical type rearrangement, one manufacturing procedure can be directly entered down, eliminate the additional effort of operator, improve work efficiency, reducing production cost, result of use is good.
