Description

Technical Field

[0001] The invention relates to the technical field of ironing machines, in particular to a novel four-roller ironing machine. Background Art

[0002] At present, two-roller or three-roller ironing machines are commonly used. When ironing one side of the fabric, the gloss effect can only be processed in one direction. The workload and efficiency of the ironing machine are not fully utilized, and the best output efficiency cannot be achieved. In the case of double-sided ironing of fabrics, the fabric can only be ironed on one side, turned over manually, and then the back of the fabric is ironed, which greatly increases production time and labor costs. Multiple ironing causes cumulative errors, and the ironing quality and appearance texture are poor.

[0003] The traditional cloth-supporting belt clutch device and cloth-supporting belt deviation correction device are used in the ironing machine. The cloth-supporting belt clutch device includes a synchronous connection plate arranged on both sides of the fixed roller and the swing roller. The synchronous connection plate is hinged with a clutch cylinder. The clutch cylinder pushes the cloth-supporting belt to make a clutch movement relative to the ironing roller. The shaft end of the clutch cylinder is hinged with a synchronous roller through a crankshaft. The shaft end of the synchronous roller is provided with a limit link. The limit link rotates synchronously with the synchronous roller. The free end of the limit link rotates continuously and contacts the shaft end of the reducer. The shaft end of the reducer is telescopic to push the limit link to rotate at a small angle, which in turn drives the limit link to fine-tune the displacement, and finally achieves the distance adjustment between the cloth-supporting belt and the ironing roller. The entire cloth-supporting belt clutch device is complicated to operate, has a large movement stroke, occupies a large amount of space, has high requirements for component matching accuracy, and has high installation costs.

[0004] The existing ironing machine includes a fixed roller, a swing roller, a correction roller and a cloth support belt wound therebetween. Correction components are provided on both sides of the correction roller, and tensioning components are provided on both sides of the swing roller. The tensioning component and the correction component cooperate with each other, and the offset displacement is sensed in real time by a sensor. The correction roller is driven by the correction component to make fine adjustments for correction. However, the whole device occupies a large space and has a complex structure. During the manufacturing process, the accuracy standards of the coordination of various components are increased, and the probability of error in correction is high, which cannot meet the correction requirements.

[0005] During the ironing process, multiple ironing rollers generate a large amount of high-temperature oil smoke. The top suction hood can only effectively and timely suck the oil smoke generated by the ironing rollers close to the top suction hood, which is sucked out in a timely and rapid manner by the top suction hood. However, the oil smoke generated by the ironing rollers far from the top suction hood during the ironing process cannot be effectively removed. The ironing machine is also equipped with a side suction hood, which is provided with a long strip suction port along the bottom of the hood body. Through one or both sides of the suction, a large amount of oil smoke generated during the ironing process of the ironing rollers is unevenly sucked, resulting in uneven surface temperature of the ironing roller body, affecting the ironing effect of the fabric. At the same time, the internal temperature of the ironing machine is increased, the heat dissipation efficiency is low, a large amount of heat and smoke are generated during the operation, and the high-temperature oil smoke seriously fumes the fabric.

[0060] Example 2

[0061] The cloth is threaded before ironing. After threading, the cloth needs to be ironed. The cloth support belt clutch device is used to adjust the relative position of the cloth and the ironing roller.

[0062] A hinge hole 333 is provided on the plate body of the synchronous connecting plate 303 of the cloth-supporting belt clutch device 3, which is close to the swing roller. The cylinder shaft end of the clutch cylinder 302 is hinged to the synchronous connecting plate through the hinge hole. The clutch cylinder shaft drives the swing roller to rotate and swing around the center of the fixed roller.

[0063] The gauge adjustment mechanism 1 comprises a gauge roller 101, a gauge motor 102 is provided at one end of the gauge roller body, an angle sensor 103 is provided at the end of the gauge roller body, the gauge motor shaft is coaxially arranged with the gauge roller, an eccentric ring plate 104 is provided on the gauge roller body, a first fixing hole is provided on the flange of the eccentric ring plate, a U-shaped positioning block is provided at the bottom of the clutch cylinder body, second fixing holes are penetrated on the two side plates of the U-shaped positioning block, the first fixing hole and the second fixing hole are connected through a fixing shaft 141, and the angle interval formed by the reciprocating rotation of the gauge motor corresponds to the gauge size formed by the rotation of the gauge roller.

[0064] Angle sensor 103 is installed at the end of the gauge roller body to monitor the rotation angle of the gauge roller in real time and adjust it reliably and accurately. The gauge motor is coaxially arranged with the gauge roller, and the gauge motor drives the rotation of the eccentric ring plate to accurately adjust the rotation angle of the gauge roller, thereby realizing accurate control of the gauge size.

[0065] The cloth passes through the ironing gap along the gauge adjustment mechanism 1 for ironing. The ironing gap is automatically and accurately adjusted according to the thickness or texture of the cloth through the cooperation of the clutch cylinder 302 and the gauge adjustment mechanism 1.

[0066] Before the ironing machine is started, the clutch motor drives the synchronous connection plate to rotate away from the ironing roller, driving the swing roller to rotate along the fixed roller, the cloth support belt is away from the ironing roller, and the ironing gap is increased.

[0067] The meshing gear assembly includes a large gear 612 and a small gear 611 meshed with each other, the large gear is keyed to the end of the fixed roller shaft, the small gear 611 is keyed to the end of the angle roller shaft, an angle cylinder is also provided at the end of the angle roller shaft, the end of the angle cylinder is perpendicular to the angle roller shaft, an arc groove 17 is provided along the outer ring direction of the large gear on the frame corresponding to the angle roller shaft, and the angle roller reciprocates along the arc groove.

When the gauge motor rotates to the ironing gap corresponding to the thickness of the fabric, the gauge motor stops rotating. The eccentric ring plate drives the swing roller 301 to swing, effectively adjusting the ironing gap, thereby controlling the contact pressure of the fabric during the ironing process, and obtaining uniform heating during the ironing process.

[0070] After ironing is completed, the clutch motor drives the synchronous connecting plate to rotate away from the ironing roller, driving the swing roller to rotate along the fixed roller, and the cloth support belt moves away from the ironing roller. The ironing gap becomes larger, and the fabric is moved out for next use.
