In this case, the cloth inspecting machine also comprises a tension-maintaining mechanism for controlling and maintaining a constant tension on the cloth passing through the passage.

Specifically, the rack comprises a first support frame j1, a second support frame j2, a third support frame j3 and a fourth support frame j4 which are independently arranged, the first support frame j1, the second support frame j2, the third support frame j3 and the fourth support frame j4 are sequentially arranged at intervals in the horizontal direction, and the unwinding mechanism, the first detection unit, the second detection unit and the winding mechanism are respectively arranged on the first support frame j1, the second support frame j2, the third support frame j3 and the fourth support frame j 4.

In this example, the first detection unit includes a first cloth inspection plate 21 and a plurality of first guide rollers 22 for guiding cloth, which are arranged on a second support frame j2, the second detection unit includes a second cloth inspection plate 31 and a plurality of second guide rollers 32 for guiding cloth, which are arranged on a third support frame j3, and both the first cloth inspection plate 21 and the second cloth inspection plate 31 are light guide cloth inspection plates with adjustable brightness, so that the eye fatigue of staff can be reduced;

The first detection unit further comprises a first work platform t1 formed between the first support frame j1 and the second support frame j2 and used for people to stand for work, and the second detection unit further comprises a second work platform t2 formed between the second support frame j2 and the third support frame j3 and used for people to stand for work (standing areas for the people to stand are formed above the first work platform t1 and the second work platform t 2), wherein the first cloth inspecting plate 21 is higher than the second cloth inspecting plate 31, and the first work platform t1 is higher than the second work platform t 2; the height difference between the first cloth inspecting plate 21 and the second cloth inspecting plate 31, the first work platform t1 and the second work platform t2 is designed such that a section of the passageway between the first support frame j1 and the second support frame j2 can pass under the first work platform t1 and reach the first guide roller 22 at the bottom of the first inspection unit, then extend upward to the first guide roller 22 at the top of the first inspection unit via the first cloth inspecting plate 21, then pass over the standing area on the second work platform t2 to the second guide roller 32 at the top of the second inspection unit, then pass through the second cloth inspecting plate 31 and extend downward to the second guide roller 32 at the lower part of the second inspection unit, and then extend toward the winding mechanism. The layout of the first detection unit and the second detection unit and the extending direction of the channel provide a solid foundation for realizing double-sided cloth inspection and providing an operation field convenient for personnel operation of the cloth inspecting machine.

Further, the unwinding mechanism comprises an unwinding roller 12 arranged on the first support frame j1, a first driving mechanism 11 arranged on the first support frame j1 and used for driving the unwinding roller 12 to rotate and unwind, and a plurality of unwinding guide rollers 13 arranged on the first support frame j 1; the winding mechanism comprises a winding roller 42 arranged on a fourth support frame j4, a second driving mechanism 41 arranged on a fourth support frame j4 and used for driving the unwinding roller 12 to rotate and unwind, and a plurality of winding guide rollers 43 arranged on the fourth support frame j 4. The first driving mechanism 11 and the second driving mechanism 41 both comprise driving motors, and the power source of the cloth movement of the cloth pressing machine is only provided by the first driving mechanism 11 and the second driving mechanism 41, and no other driving device is arranged, so that the whole arrangement is convenient, and the cost is correspondingly lower.

the tension constant mechanism is arranged on the first support frame j 1; specifically, the tension constant mechanism includes a tension control roller 50 which is arranged to swing between two adjacent unwinding guide rollers 13 in the extending direction of the passage, and a driving assembly which tends to drive the tension control roller 50 to swing to increase the tension of the cloth, and the driving assembly includes a swing arm 51 which is rotatably arranged on a first support frame j1, a telescopic cylinder 52 (which may also be an elastic member or the like capable of providing a pushing force) which provides power for the swing arm 51 to swing, and a connecting rod 53 which is connected between the swing arm 51 and a power output shaft of the telescopic cylinder 52. The tension control roller 50 is arranged at the lower end part of the swing arm 51 in a way of rotating around the axis of the tension control roller, the middle part of the swing arm 51 is arranged on the first support frame j1 in a way of rotating, more than the middle part of the swing arm 51 forms a balance weight, in addition, the installation surface of the cylinder body of the telescopic cylinder 52 and the installation surface of the swing arm 51 are not in the same plane and are arranged in a staggered way, so when the swing arm 51 swings, the upper end of the swing arm 51 cannot impact the cylinder body of the telescopic cylinder 52, and the two do. One end of the connecting rod 53 is fixedly connected with the middle of the swing arm 51, the other end of the connecting rod is always in butt joint with the power output shaft of the telescopic cylinder 52 in a butting mode, how the power output shaft of the telescopic cylinder 52 is connected with the connecting rod 53 is not limited, the two can be connected through an elastic body or directly in butting mode, when the swing arm 51 swings to drive the connecting rod 53 to swing and rotate, the power output shaft of the telescopic cylinder 52 cannot interfere with the swinging and rotating of the connecting rod 53, in the embodiment, a large round hole is formed in the end portion of the power output shaft of the telescopic cylinder 52, a transmission shaft which is located in the horizontal direction and is perpendicular to the power output shaft of the telescopic cylinder 52 is connected to the end portion of the connecting rod 53, the transmission shaft is always in butting mode on the side wall of the.

As shown in fig. 2, the telescopic cylinder normally abuts against the connecting rod, that is, the telescopic cylinder has a tendency of pushing the swing arm to deflect leftward in the normal state, when the tension is too large, the cloth will pull the tension control roller, so that the swing arm deflects rightward and overcomes the pushing force of the telescopic cylinder, the power output shaft of the telescopic cylinder retracts, when the tension is small, the telescopic cylinder will push, and finally the swing arm deflects leftward, and the above "left" and "right" are based on fig. 2.

In conclusion, the constant-tension cloth inspecting machine can perform defect detection on the front side and the back side of the cloth on one detection production line through redesigning the integral structure, solves the problem that the defects on the back side of the high-gram-weight cloth cannot be eliminated, and performs accurate tension control by adopting the tension constant mechanism, so that the requirement of high-quality end faces is met. And through the change of structural configuration for the button such as opening of equipment stops, add speed reduction arranges the position more rationally, also provides comparatively humanized work place for the personnel, and personnel's operation no longer receives the place limitation, and it is more handy convenient to operate.

The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
