Coiler
Technical field:
The present invention relates to the textile dyeing machinery apparatus field, specifically is a kind of in clot processes such as cloth, can avoid the cloth surface wrinkling, thereby guarantees the coiler of yardage roll quality.
Background technology:
As everyone knows, coiler is the final terminal of manufacturing lines such as knitted fabric, film, weaving cloth, and the product after it is mainly finished production carries out clot.At present, the rolling inflatable axle that coiler of the prior art generally comprises frame, be rotatably connected with frame, be connected be used for driving the winding motor of rolling inflatable axle rotation on the frame and be used for production finished after the conveyer that transmits of product, conveyer is positioned at frame one side.Surface wrinkling phenomenon occur because of being subjected to pulling force for fear of elasticity cloth in the clot process, coiler of the prior art also is connected with a spreading roll that the cloth surface can be flattened on frame, and this spreading roll is positioned at rolling inflatable axle one side.During work, need the cloth of clot at first to pass to spreading roll by conveyer, after flattening the cloth surface, spreading roll is delivered on the rolling inflatable axle then, meanwhile, rolling inflatable axle can begin rotation under the drive of winding motor, and constantly with the cloth clot to rolling inflatable axle, finally finish whole clot process.Though the prior art coiler can flatten the cloth surface under the effect of spreading roll, but, because spreading roll of the prior art all is to be fixedly mounted on the frame usually, in other words, the central axis of the central axis of spreading roll and rolling inflatable axle has a segment distance, and the cloth after being flattened by spreading roll the surface wrinkling phenomenon still can occur during through this segment distance, therefore causes the yardage roll unfairness after the clot, thereby influences the clot quality.
Summary of the invention:
The technical problem to be solved in the present invention is, provides a kind of and can avoid the cloth surface wrinkling in cloth clot process, thereby guarantee the coiler of yardage roll quality.
Technical solution of the present invention is, a kind of coiler with following structure is provided: it comprises frame, spreading roll, the rolling inflatable axle that is rotatably connected with frame, be connected and be used for driving the winding motor of rolling inflatable axle rotation and the conveyer that is used to transmit cloth on the frame, conveyer is positioned at frame one side, spreading roll is positioned at rolling inflatable axle one side, wherein, it also comprises the spreading roll support, guide rail, left rail support and right rail brackets, left rail support and right rail brackets all are connected on the frame, guide rail is connected between left rail support and the right rail brackets, spreading roll is rotatably connected on the spreading roll support, and the spreading roll support is connected on the guide rail slidably.
Coiler of the present invention wherein, is connected with extension spring between spreading roll support and the left rail support.
After adopting above structure, compared with prior art, coiler of the present invention has the following advantages: because spreading roll is rotatably connected on the spreading roll support, and the spreading roll support can horizontally slip at the effect lower edge of cloth friction force guide rail, in other words, when rolling inflatable axle has just begun clot, spreading roll can abut against under the effect of cloth friction force near the rolling inflatable axle, promptly slide into the guide rail high order end, and when the cloth diameter on the rolling inflatable axle constantly increases, spreading roll then can slowly move right at the effect lower edge of cloth friction force guide rail, therefore, coiler of the present invention is in whole clot process, spreading roll can both be close near the rolling inflatable axle, thereby guaranteed that the cloth surface can be involved in rolling inflatable axle immediately after being flattened by spreading roll, effectively avoided the cloth surface wrinkling phenomenon that causes because of distance relation, guaranteed the yardage roll quality after the clot.
Description of drawings:
Accompanying drawing is the structural representation of coiler of the present invention.
The specific embodiment:
Below in conjunction with the drawings and specific embodiments coiler of the present invention is described further:
As shown in drawings, in this specific embodiment, coiler of the present invention comprises frame 13, rolling inflatable axle 1, spreading roll 2, spreading roll support 4, guide rail 3, left rail support 15, right rail brackets 5, be connected and be used for driving the winding motor 12 of rolling inflatable axle 1 rotation and the conveyer that is used to transmit cloth 10 on the frame 13, the two ends of rolling inflatable axle 1 are rotatably connected on the frame 13, be connected with driving band 14 between rolling inflatable axle 1 and the winding motor 12, spreading roll 2, spreading roll support 4, guide rail 3, left rail support 15 and right rail brackets 5 all are positioned at the right side of rolling inflatable axle 1, left rail support 15 and right rail brackets 5 all are connected on the frame 13, guide rail 3 is connected between left rail support 15 and the right rail brackets 5, in other words, the left end of guide rail 3 is connected on the left rail support 15, its right-hand member is connected on the right rail brackets 5, spreading roll 2 is rotatably connected on the spreading roll support 4, spreading roll support 4 is connected on the guide rail 3 slidably, be connected with the 3rd hold-down roller 17 on frame 13 right side walls, conveyer is positioned at frame 13 right sides, conveyer specifically comprises transfer station 11 and is rotatably connected to first hold-down roller 9 on the transfer station 11, jockey pulley 8, transition roller 16 and second hold-down roller, 18, the second hold-down rollers 18 are positioned on the left side wall of transfer station 11.Be connected with tension pick-up (not shown), automatic tension controller 7 and frequency-variable controller 6 between jockey pulley 8 and the winding motor 12, tension pick-up one end is connected with jockey pulley 8, the other end is connected with automatic tension controller 7 one ends, automatic tension controller 7 other ends are connected with frequency-variable controller 6 one ends, and frequency-variable controller 6 other ends are connected with winding motor 12.In this specific embodiment, be connected with an extension spring 19 between spreading roll support 4 and the left rail support 15, being provided with of extension spring 19 can guarantee that spreading roll 2 abuts against near the rolling inflatable axle 1 all the time.
Principle of work of the present invention is: after connecting the power supply of winding motor 12, winding motor 12 begins rotation, driving band 14 is delivered to the rotary torque of winding motor 12 on the rolling inflatable axle 1, at this moment, rolling inflatable axle 1 beginning circumference rotates, spreading roll 2 arrives guide rail 3 high order ends in the friction force effect lower slider of cloth 10, and along with the cloth diameter on the rolling inflatable axle 1 constantly increases, 2 of spreading rolls can slowly move right at the friction force effect lower edge of cloth 10 guide rail 3.In the clot process, transmission of pressure when tension pick-up can pass through jockey pulleys 8 with cloth 10 is given automatic tension controller 7, automatic tension controller 7 passes to signal frequency-variable controller 6 after having analyzed data again, and final signal is passed to winding motor 12, and rely on this signal to control the rotating speed of winding motor 12 by frequency-variable controller 6.
