The main frame is provided with a cloth feeding frame 1, a cloth feeding roller is arranged on the cloth feeding frame and is rotatably connected with the cloth feeding frame, a checking main roller is rotatably connected with the main frame, and a checking auxiliary roller is rotatably connected with the main frame. The cloth roller both ends all are equipped with roller seat 32, are equipped with the roller hole with cloth roller tip adaptation on the roller seat, and cloth roller one end stretches into the roller downthehole of a roller seat, and the cloth roller other end stretches into the roller downthehole of another roller seat, cloth roller and roller seat normal running fit, cloth roller axis level, the roller seat passes through the screw and is connected with the winding stand.

The cloth enters from the cloth feeding frame, passes through the cloth clamping and conveying part, sequentially bypasses the upper part of the inspection main roller, passes above the inspection main flat plate (clings to the top surface of the inspection main flat plate), bypasses the upper part of the inspection auxiliary roller and is finally wound to the cloth roller. The cloth pinch portion can clamp the cloth and enable the cloth to advance, the cloth rubs with the two cloth feeding rollers when passing between the two cloth feeding rollers, one cloth feeding roller rotates actively and provides power, the other progressive roller rotates passively, and the two progressive rollers rotate in opposite directions, so that the cloth can be driven to advance continuously, and the effects of guiding and keeping stable feeding are achieved. The cloth continuously advances, so an operator can continuously check the quality of the cloth (observe whether the warps and the wefts are missing or not, whether the surface is damaged or not and the like), and the cloth roller at the rear part can automatically wind the checked cloth to form a roll, so that the cloth roller is favorable for collection and subsequent use (after the cloth is wound, the cloth roller is directly dismounted). A plurality of LED fluorescent tubes can directly provide illumination for the cloth (inspection position is exactly the inspection hole, it is best not less than the cloth width to need to pay attention to the inspection hole width, so can ensure by the cloth section of inspection can be shone by the light source completely, otherwise will appear the cloth edge by the condition that inspection owner's flat board blocked, be unfavorable for observing the inspection). The operator can put on by the main frame, and the cloth of direct observation through the inspection hole (interior illumination structure shines from the cloth back, and the operator openly observes from the cloth), and owing to not light sources such as traditional fluorescent lamp, but utilize the LED light source, the illumination that has ensured the inspection position is more even, does benefit to and observes and inspect. Moreover, since only the inspection hole can transmit light, the other parts of the cloth except the section right above the inspection hole are dark (the back surface is not glossy), so the invention has small interference to an operator and is beneficial to the operator to focus attention to observe and inspect. If the cloth is wrinkled, the adjusting cylinder can drive the steam iron to move downwards, so that the steam iron is in contact with the cloth, the cloth is ironed in the advancing process of the cloth, and the cloth is enabled to be relatively flat before reaching the inspection position.

The winding transition roller can be selectively used, and the cloth can smoothly advance as long as the proper tension degree of the cloth can be ensured.

Example 2: the basic structure of this embodiment is the same as that of embodiment 1, except that, as shown in fig. 2 to 5, two self-adjusting mechanisms 5 and at least one adjusting transition roller are arranged between the main frame and the winding frame, the two self-adjusting mechanisms are symmetrically arranged along a symmetry plane, the axis of the inspection main roller is perpendicular to the symmetry plane, the self-adjusting mechanism comprises an adjusting frame 51, a cloth-shifting wheel 52, a blower, an air-guiding impeller 55, an air suction pipe 53 arranged on the adjusting frame, and a cloth-guiding flat plate 54 for attaching to the bottom surface of the cloth to support the cloth, and the axis of the cloth-shifting wheel is horizontal and perpendicular to the axis of the inspection main roller; in a self-adjusting mechanism: the cloth poking wheel comprises a wheel body 521 and a plurality of elastic poking sheets 522 used for poking the cloth on the cloth guide flat plate to enable the cloth on the cloth guide flat plate to move towards the direction far away from the symmetrical plane, the elastic poking sheets are fixed on the peripheral surface of the wheel body and are uniformly distributed along the circumferential direction of the wheel body, the axis of the cloth poking wheel is parallel to the elastic poking sheets, the cloth guide flat plate is provided with air suction holes 541 which penetrate through the upper and lower plate surfaces of the cloth guide flat plate, each air suction pipe comprises a first air pipe 531 which is vertically arranged, a second air pipe 532 which is horizontally arranged and a third air pipe 533 which is horizontally arranged, the upper end of the first air pipe is communicated with the air suction holes, the lower end of the first air pipe is communicated with the inlet of the second air pipe, the outlet of the second air pipe is communicated with the inlet of the third air pipe, the axis of the third air pipe is parallel to the axis of the cloth poking wheel, a blower is arranged in the first air pipe, the blowing direction of the first air pipe is from the upper end to the lower end of the first air pipe, and an air guide impeller is arranged in the third air pipe, the air guide impeller can rotate relative to the third air pipe, the air guide direction of the air guide impeller is from an inlet of the third air pipe to an outlet of the third air pipe, the rotation axis of the air guide impeller is overlapped with the axis of the third air pipe, a driving belt pulley 561 coaxially connected with the air guide impeller is arranged in the third air pipe, a driven belt pulley 562 coaxially connected with the cloth poking wheel is arranged on the cloth poking wheel, the axis of the driving belt pulley is parallel to the axis of the driven belt pulley, a driving belt 563 with a closed head and tail bypasses the driving belt pulley and the driven belt pulley, and the driving belt penetrates through the pipe wall of the third air pipe; two cloth wheels in two self-adjusting mechanism are dialled soon to opposite, and the lowest of adjusting the transition roller is less than and leads dull and stereotyped top surface of cloth, and the lowest of adjusting the transition roller is less than and examines the lowest of auxiliary roll, adjusts transition roller axis level. The wind guide impeller can rotate relative to the third air pipe in various forms, such as: a fixing ring fixed with the third air pipe is arranged in the third air pipe, an axle coaxially connected with the air guide impeller is arranged on the air guide impeller, and the axle is rotatably connected with the fixing ring. The cloth is driven by various cloth guide structures (such as a cloth feeding roller) to advance before being wound to the cloth roller, and in the embodiment, the cloth needs to bypass the bottom of the adjusting transition roller and then pass through the top surface of the cloth guide flat plate after bypassing the inspection auxiliary roller, and then enters the winding frame (finally reaches the cloth roller). When the fabric is furled and rolled, the situation that the deviation of the fabric is too much can be avoided, at the moment, if the fabric is continuously rolled, the finally formed fabric roll is uneven and has serious wrinkles, and even the fabric is pulled and damaged due to the fact that the tension of two sides is too asymmetric when the fabric is rolled. In this embodiment, the fabric is passed through two symmetrical self-adjusting mechanisms before being rolled, and the fabric is advanced against the fabric guide plate. Two sides of the cloth are respectively positioned above the two air suction holes, but the two air suction holes are not completely covered. Under the action of the air guide machine, air is sucked from the air suction hole and is discharged after passing through the first air pipe, the second air pipe and the third air pipe. In the process, the air guide impeller is blown by air flow, the cloth poking wheels are driven to rotate by the driving belt wheel, the transmission belt and the driven belt wheel, so that the elastic pieces on the cloth poking wheels can continuously poke cloth, and the poking forces provided by the two cloth poking wheels are just opposite due to the fact that the rotating directions of the two cloth poking wheels are opposite (the technical scheme is recorded in the technical scheme, in a self-adjusting mechanism, the cloth poking wheels comprise wheel bodies and a plurality of elastic poking pieces used for poking the cloth on the cloth guide flat plate to enable the cloth on the cloth guide flat plate to move towards the direction far away from the symmetrical plane, so in the visual angle of figure 4, the cloth poking wheel on the left side rotates clockwise, and the cloth poking wheel on the right side rotates anticlockwise).

When the cloth material distributing device works, the two air guide fans are started (the rotating speeds of the two air guide fans are the same), when the cloth material is slightly deviated, the ranges covered by the cloth material above the two air suction holes are basically the same, and therefore the air inlet calibers of the two air suction holes are basically the same. At this moment, under the effect of two air guide fans, the air flow velocity in the two suction pipes is the same, and the air guide impeller is blown by the air flow, so that the rotating speeds of the two air guide impellers are basically the same. Therefore, the rotating speeds of the two cloth poking wheels driven by the air guide impeller are basically consistent, the poking force of the elastic sheet on the air guide impeller to the cloth is basically consistent, the cloth can only slightly move back and forth in the left and right directions (the left and right directions are perpendicular to the cloth advancing direction on the cloth guide flat plate and are parallel to the horizontal plane) (so the cloth can slightly move back and forth), the poking of the cloth by the elastic sheet is not continuous, when the elastic sheet on one cloth poking wheel contacts the cloth, the elastic sheet on the other cloth poking wheel may not contact the cloth, however, for any cloth poking wheel, the time interval of the elastic sheet on the cloth poking wheel contacting the cloth is short, so the amplitude of the cloth moving back and forth is small), at the moment, the cloth can be considered to be in a qualified state (the cloth is in a range allowing deviation), and at the moment, the cloth can be normally rolled on the cloth roller.

When the cloth material has a larger deviation, the range covered by the cloth material above the two air suction holes is also larger (when the cloth material deviates to one side, the air suction hole on the side is covered more by the cloth material, and the air suction hole on the other side is covered less by the cloth material). At the moment, the air inlet volumes of the two air suction pipes are obviously different, so that the air flow velocities in the two air suction pipes are greatly different even if the rotating speeds of the air guide fans are the same, so that the rotating speeds of the two air guide impellers are different, and the rotating speeds of the two cloth poking wheels are different. The cloth is more to which side, the air inlet volume of the air suction pipe of the side is smaller, the rotating speed of the air guide impeller and the rotating speed of the cloth poking wheel of the side are smaller, otherwise, the rotating speed of the cloth poking wheel of the other side is larger, so the cloth can be poked to the other side by the cloth poking wheel of the other side on the whole, and the correction of the position of the cloth can be automatically realized. Once properly aligned, the fabric will again be in "acceptable condition" as previously described.

In a self-adjusting mechanism: and an air blowing nozzle used for blowing air to the cloth on the cloth guide flat plate is arranged beside the cloth guide flat plate, a connecting air pipe is arranged on the air blowing nozzle, one end of the connecting air pipe is communicated with the air blowing nozzle, the other end of the connecting air pipe is communicated with an outlet of a third air pipe, and the air blowing nozzle is fixed on the adjusting rack through a nozzle connecting rod. The air discharged from the outlet of the third air pipe is not directly discharged to the outside, but is blown to the cloth on the cloth guide flat plate through the connecting air pipe and the air blowing nozzle, so that impurities such as dust on the cloth can be blown away, the coiling quality is guaranteed, and the air flow utilization rate is improved. Generally, the soot blowing operation needs to be performed on only one side of the cloth, since most of the cloth is permeable to air. If the cloth is airtight, the blowing nozzle can be arranged at the bottom of the cloth at the inspection position according to requirements, and the blowing nozzle at the bottom of the cloth is communicated with the outlet of the third air pipe through an additional connecting air pipe.

In a self-adjusting mechanism: a plurality of adjusting transition belt wheels 564 are arranged on the adjusting frame, and the transmission belt bypasses all the adjusting transition belt wheels. The transition belt wheel can change the trend of the transmission belt and avoid the interference between the transmission belt and other structures. The arrangement position and the number of the transition pulleys can be determined according to the actual structure position and the requirement.

Two traverse devices which are symmetrically arranged along the symmetrical plane are arranged between the main frame and the winding frame, the traverse devices correspond to the self-adjusting mechanisms one by one, each traverse device comprises an electric slide rail and an electric slide block matched with the electric slide rail, the slidable direction of the electric slide block is vertical to the symmetrical plane, and in the traverse devices and the self-adjusting mechanisms which correspond to each other: the self-adjusting mechanism is arranged on the electric sliding block. When the width of the cloth to be detected is different from that of the cloth detected last time, the cloth inspection device can be adaptively adjusted, and only the two sliding blocks are required to slide to drive the two self-adjusting mechanisms to be close to or far away from each other so as to adjust the cloth to a proper position (the cloth can cover a part of the air suction hole but does not completely cover the air suction hole).
