[0002] After the grey cloth, gauze or finished cloth is continuously output from the production line, it needs to be rolled up through processes such as cloth pressing and winding. The function of the cloth press is to flatten the continuously output cloth. During the flattening process, wrinkles are easily generated at the corners, so it is necessary to use an air blower to blow air from the center line to the edge of the cloth to eliminate wrinkles and smooth the edge of the cloth.

[0003] At present, the above edge blowing operations are still done manually, and the labor productivity is low. Summary of the invention

[0020] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings.

[0021] Embodiment 1

[0022] like Figure 1 , Figure 2It can be seen that the automatic edge blowing device with adjustable direction of this embodiment includes a slider 2 movably connected to the crossbeam 1 of the cloth press, and a positioning ring 20 and a guide rod 21 are welded on the outer side of the slider 2, and the guide rod 21 is arranged on the central axis of the positioning ring 20; it also includes a compression spring 3 and a guide cylinder 4 which are sequentially sleeved on the guide rod 21, the root of the guide cylinder 4 is set as a retaining ring 40, and its free end is set as a bayonet 41, and a nozzle 5 is clamped in the bayonet 41, and the nozzle 5 is connected to the compressed air source through a hose 6; the automatic edge blowing device with adjustable direction also includes an end cover 7, a through hole matching the guide cylinder 4 is opened in the center of the end cover 7, the aperture of the through hole is smaller than the diameter of the retaining ring 40, and the end cover 7 is threadedly connected to the positioning ring 20.

[0023] In this embodiment, the cross beam 1 of the cloth press machine is a steel box beam with a rectangular cross section. The cross section of the slider 2 is a "7"-shaped structure, and the deadweight is reduced as much as possible under the premise of meeting the motion coordination with the steel box beam.

[0024] Assembly process: First, slightly compress the bayonet 41 at the free end of the guide tube 4 to allow it to pass through the through hole of the end cover 7. The retaining ring 40 is restricted by the through hole, and the guide tube 4 will not be separated from the end cover 7. Then, the compression spring 3 is mounted on the guide rod 21, and the guide tube 4 is also mounted on the guide rod 21. The end cover 7 is aligned with the positioning ring 20. The operator presses the end cover 7 and rotates it to make the two threadedly connected. Then, the nozzle 5 is fixed in the bayonet 41, and the hose 6 is ventilated.

[0025] Operation process: Figure 2 It can be seen that the cloth 10 is horizontally arranged under the crossbeam 1 of the cloth press through the frame, guide rollers and other devices, and is passed continuously. The position of the slider 2 is adjusted according to the width of the cloth, and then the guide cylinder 4 is pressed to separate the retaining ring 40 from the inner surface of the end cover 7, and then the guide cylinder 4 is rotated so that the nozzle 5 obtains a suitable angle. The operator releases the guide cylinder 4, the retaining ring 40 contacts the end cover 7, the compression spring 3 is tightened, and the angle of the nozzle 5 is fixed. The cloth 10 moves continuously, and the nozzle 5 continues to spray air, blowing the edge of the cloth 10 with a strong airflow from the center line to the edge direction, so as to eliminate wrinkles and make the edge of the cloth smooth.

[0026] Embodiment 2

[0027] On the basis of the first embodiment, this embodiment adds an automatic positioning function of the slider 2 .

[0028] like Figure 3 , Figure 4 It can be seen that the slider 2 is connected to the crossbeam 1 via two rollers 22 under its upper end cover, and a motor 8 is fixedly provided on the slider 2 , and the main shaft of the motor 8 is transmission-connected to one of the rollers 22 .

[0029] It also includes an inner photoelectric sensor 9 and an outer photoelectric sensor 9' fixed to the slider 2 through a bracket, wherein the detection direction of the inner photoelectric sensor 9 and the outer photoelectric sensor 9' faces downward, and a controller connected to the motor 8 and the photoelectric sensor.

[0030] In this embodiment, the purpose of setting the inner photoelectric sensor 9 and the outer photoelectric sensor 9' is: A. Automatically and accurately controlling the position of the slider 2 according to the width of the cloth; B. During the operation, if wrinkles appear on the edge of the cloth, the system automatically jumps the horizontal position of the slider 2, thereby adjusting the horizontal position of the nozzle 5 to achieve real-time monitoring.

[0031] Device initialization process:

[0032] First, the operator presets the detection distance of the photoelectric sensor according to the requirements of the workstation; presets the distance between the inner photoelectric sensor 9 and the outer photoelectric sensor 9', and presets the distance between the inner photoelectric sensor 9 and the slider 2. Manually adjust the angle of the nozzle 5. With the midpoint of the beam 1 as the reference, move the slider 2 and the attached mechanism to the far end of the beam 1. Then the system is powered on, the cloth 10 starts to move, and the nozzle 5 starts to blow air.

[0033] In an ideal state, in the vertical projection direction, the edge of the cloth 10 is located directly below the inner photoelectric sensor 9, and the reflection of the cloth 10 enables the inner photoelectric sensor 9 to obtain a feedback signal, while the outer photoelectric sensor 9' is located outside the edge of the cloth 10 and therefore cannot obtain a feedback signal. For ease of description, the photoelectric sensor obtaining a feedback signal is marked as state 1, and the photoelectric sensor not obtaining a feedback signal is marked as state 0. That is, the inner photoelectric sensor 9 and the outer photoelectric sensor 9' have four states: inner 1, inner 0, outer 1, and outer 0.

[0034] Find the ideal workstation during operation as follows:

[0035] When the inner position is 0 and the outer position is 0, the controller gives a signal, the motor 8 works, and the slider 2 moves toward the near end; this situation mainly occurs during the system initialization process.

[0036] When the inner 1 and outer 1 are, the controller gives a signal, the motor 8 works, and the slider 2 moves to the far end; this situation may occur when the motor 8 moves too much; in addition, if wrinkles appear on the edge of the cloth, the width of the cloth will be reduced, which will also cause this situation. The above situations will be monitored and correction signals will be given.

[0037] When the inner position is 1 and the outer position is 0, the slide block 2 is in the ideal position. At this time, the motor 8 does not work, and the slide block 2 is positioned in situ.

[0038] The above control systems can firstly achieve the system initialization function, and secondly, during normal operation, the above control systems are all monitored online to ensure that they are always in the ideal working position.

[0039] The specific implementation methods of the present invention include but are not limited to the above-mentioned embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and modifications according to the present invention, but still fall within the protection scope of the present invention.
