[0043] The deviation detection device includes a first deviation detection and adjustment electric cylinder 33 and a second deviation detection and adjustment electric cylinder 34 symmetrically arranged with respect to the first deviation detection and adjustment electric cylinder 33.

[0044] In this embodiment, the offset of the fabric during the detection process can be detected in real time by means of the first offset measurement light curtain 37 and the second offset measurement light curtain 38. When the offset is large, it is convenient for the staff to make timely adjustments. The first offset detection adjustment electric cylinder 33 and the second offset detection adjustment electric cylinder 34 can adjust the distance between the first offset detection frame 35 and the second offset detection frame 36, thereby realizing the offset detection of fabrics of different widths and improving the applicability of the equipment.

[0045] In this embodiment, the distance detection sensor, adjusting electric hydraulic cylinder, guiding adjusting hydraulic cylinder, pressure sensor, visual inspection camera, deviation detection adjusting electric hydraulic cylinder, and deviation measurement light curtain are all connected to an external computer detection and control system. The actions of the corresponding electric hydraulic cylinders can be controlled by this control system. This is an existing technical solution and will not be described in detail here.

[0046] Working principle: The fabric is placed between the first guide roller 16 and the first docking roller 18, and between the second guide roller 17 and the second docking roller 19. The distance between the first limit block 4 and the second limit block 5 is adjusted by the first adjusting electric cylinder 7, the second adjusting scheduling cylinder and the first distance detection sensor 6, so that the distance between them matches the width of the fabric. The distance between the third limit block 11 and the fourth limit block 12 is adjusted by the third adjusting electric cylinder 14, the fourth adjusting scheduling cylinder and the second distance detection sensor 13, so that the distance between them matches the width of the fabric. At this time, the fabric is limited between the first limit block 4 and the second limit block 5, and between the third limit block 11 and the fourth limit block 12.

[0047] During the adjustment process, each adjusting electric cylinder moves synchronously, and before and after adjustment, the first limit block 4 is aligned with the third limit block 11, and the second limit block 5 is aligned with the fourth limit block 12.

[0048] After the fabric is positioned, the first guide adjustment cylinder 24 is activated to drive the first docking roller 18 downward, so that the first docking roller 18 presses against the fabric surface with a certain pressure. The second guide adjustment cylinder 25 is activated to drive the second docking roller 19 downward, so that the second docking roller 19 presses against the fabric surface with a certain pressure. This operation can generate a guide friction force between the fabric and the corresponding roller.

[0049] The first deviation detection and adjustment electric cylinder 33 is activated, which drives the first deviation detection frame 35 to move backward, so that the front edge of the fabric is between the first deviation measurement light curtains 37. The second deviation detection and adjustment electric cylinder 34 is activated, which drives the second deviation detection frame 36 to move forward, so that the rear edge of the fabric is between the second deviation measurement light curtains 38, thus realizing the deviation adjustment operation.

[0050] The conveyor motor 28 is then started to guide the fabric forward. When it passes the first visual inspection camera 31 and the second visual inspection camera 32, the inspection is completed and the fabric is marked by the external computer detection and control system.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
