[0015] For example, Figure 1 and 2As shown, the automatic opening adjustment device comprises a rack (not shown), a first swing shaft 1, a second swing shaft 2, a first uncoiling support 3, a second uncoiling support 4, a first uncoiling plate 5, a second uncoiling plate 6, a controller 7, a first servo motor 8, a second servo motor 9, a first eccentric adjustment mechanism and a second eccentric adjustment mechanism, the first swing shaft 1 and the second swing shaft 2 are arranged on the rack, the first uncoiling support 3 is rotatably arranged on the first swing shaft 1, the second uncoiling support 4 is rotatably arranged on the second swing shaft 2, the first uncoiling plate 5 is arranged on the first uncoiling support 3, the second uncoiling plate 6 is arranged on the second uncoiling support 4, a cloth gap for passing cloth is formed between the first uncoiling plate 5 and the second uncoiling plate 6, the first servo motor 8 drives the first uncoiling support 3 to swing through the first eccentric adjustment mechanism, the second servo motor 9 drives the second uncoiling support 4 to swing through the second eccentric adjustment mechanism, and the controller 7 is signal connected with the first servo motor 8 and the second servo motor 9.

[0016] The first eccentric adjustment mechanism comprises a first adjustment rotating shaft 10, a first eccentric shaft sleeve 11 and a first connecting rod 12, the first servo motor 8 drives the first adjustment rotating shaft 10 to rotate, the upper end of the first connecting rod 12 is rotatably connected with the first uncoiling support 3, and the lower end is rotatably connected with the first adjustment rotating shaft 10 through the first eccentric shaft sleeve 11, the second eccentric adjustment mechanism comprises a second adjustment rotating shaft 13, a second eccentric shaft sleeve 14 and a second connecting rod 15, the second servo motor 9 drives the second adjustment rotating shaft 13 to rotate, the upper end of the second connecting rod 15 is rotatably connected with the second uncoiling support 4, and the lower end is rotatably connected with the second adjustment rotating shaft 13 through the second eccentric shaft sleeve 14. The adjustment mode of the eccentric adjustment mechanism is introduced by taking the adjustment of the first uncoiling plate 5 as an example: the first adjustment rotating shaft 10 is driven to rotate by the first servo motor 8, the inner ring of the first eccentric shaft sleeve 11 is fixedly matched with the first adjustment rotating shaft 10, the outer ring is rotatably matched with the first connecting rod 12, the inner and outer rings of the first eccentric shaft sleeve 11 are different in shaft center, so that the first connecting rod 12 can be driven to move up and down in the rotating process of the first eccentric shaft sleeve 11, thereby driving the first uncoiling support 3 to swing along the first swing shaft 1, so as to drive the first uncoiling plate 5 to move, so as to achieve the purpose of adjusting the opening.

[0017] The first eccentric adjusting mechanism further comprises a first speed reducer 16, and the first servo motor 8 is connected with the first adjusting rotating shaft 10 through the first speed reducer 16; and the second eccentric adjusting mechanism further comprises a second speed reducer 17, and the second servo motor 9 is connected with the second adjusting rotating shaft 13 through the second speed reducer 17. The first speed reducer 16 and the second speed reducer 17 are fixedly arranged on the frame, the speed reducers reduce the transmission speed of the servo motors, so that the purpose of accurate control is achieved, power is converted to the first adjusting rotating shaft 10 and the second adjusting rotating shaft 13, the first adjusting rotating shaft 10 and the second adjusting rotating shaft 13 are driven to rotate, and then the opening gap of the delating plate is adjusted.

[0018] The self-locking structure of the transmission system can have the following implementation manners:

[0019] The first speed reducer 16 and the second speed reducer 17 are internally provided with a worm gear structure. When the servo motor is not working, the worm gear structure is used to realize self-locking, so that the gap of the delating plate is fixed.

The brake clutch is additionally arranged on the motor body of the servo motor, the brake clutch is provided with a brake clutch coil, when the motor is normally operated by being powered, the brake clutch coil is also powered, electromagnetic force is generated to overcome the spring force to open the brake clutch, and the motor can be freely rotated; when the motor is powered off, the brake clutch coil loses power, the spring force makes the brake clutch tightly hold the motor shaft, the motor shaft is prevented from rotating, and the self-locking function is realized.

[0021] The first servo motor 8 and the second servo motor 9 are provided with an electromagnetic clutch. The electromagnetic clutch is arranged between the servo motor and the first speed reducer 16 and the second speed reducer 17, when the motor needs to rotate, the electromagnetic clutch is powered, the motor is connected with the load, and the motor can drive the load to rotate; when the motor stops rotating and needs to be self-locked, the electromagnetic clutch is powered off, the power transmission between the motor and the load is cut off, and meanwhile, the braking component of the electromagnetic clutch plays a role to lock the load shaft, and the self-locking is realized.
