[0002] Tags of cloth and the like are mostly applied to clothing. The cutting process of the ultrasonic slicing machine for the tag is as follows: First, the unwinding device unwinds the tag strip wound on the tag roll and assembles the tag strip between the driving roller and the driven roller; the motor drives the driving roller to rotate to realize the transmission of the tag strip by the driving roller; the feeding device conveys the tag strip conveyed by the driving roller to the ultrasonic cutting device, and the ultrasonic cutting device cuts the tag strip, thereby obtaining one section of tag after another.

[0003] In the prior art, the speed of the driving roller for conveying the tag strip does not match the speed of the ultrasonic cutting device for cutting the tag strip, which easily causes the tag strip between the driving roller and the feeding device to gather together, and then it is easy to stack the tag strips together, resulting in wrinkles in the local area of the tag strip and unable to ensure the flatness of the tag.

[0041] An ultrasonic slicing machine with reliable feeding, as Figures 1 to 3 shown, successively includes an unwinding device 10, a feeding device 20, an ultrasonic cutting knife device 30, and a discharging device 40 along the driving direction of the label strip. A controller is connected between the unwinding device 10 and the ultrasonic cutting knife device 30.

[0042] As Figure 1 、 Figure 2 and Figure 4As shown, the unwinding device 10 includes a material rack 11, a material unwinding reel 12, a driving roller 13, a driven roller 14, and a material unwinding motor 15. Among them, the material unwinding reel 12 is rotatably assembled on the material rack 11 and is used to place the label roll. The material unwinding reel 12, the driving roller 13, and the driven roller 14 are arranged in parallel. The driving roller 13 and the driven roller 14 are distributed downstream of the material unwinding reel 12, and the driven roller 14 is arranged adjacent to the driving roller 13. The material unwinding motor 15 is assembled on the material rack 11, and its driving end is connected to the driving roller 13 to drive the material unwinding reel 12 to rotate. The unwinding device 10 uses the friction between the driving roller 13 and the driven roller 14 to convey the label strip, so as to realize the unwinding of the label roll and convey the label strip wound on the label roll to the feeding device 20.

[0043] Further, as Figures 4 to 7 shown, the driven roller 14 includes a support seat 141, a pressure roller 142, and a fixing bolt 143. Specifically, the support seat 141 is rotatably assembled on the material rack 11. The pressure roller 142 is hinged to one end of the support seat 141 away from the material rack 11. An axial connection hole is opened at the center of the support seat 141. An axial hole is opened at the center of the pressure roller 142. The fixing bolt 143 passes through the axial hole and is threadedly connected to the axial connection hole. After replacing the new label roll, unscrew the fixing bolt 143, swing the pressure roller 142 to the side away from the driving roller 13; place the label strip wound on the new label roll between the driving roller 13 and the driven roller 14, and then swing the pressure roller 142 back to its original position in the reverse direction so that the driving roller 13 and the driven roller 14 are arranged in parallel; finally, pass the fixing bolt 143 through the axial hole and threadedly connect it to the axial connection hole so that the driven roller 14 always maintains a parallel state with the driving roller 13. This structure reduces the difficulty of inserting the label strip between the driven roller 14 and the driving roller 13 and effectively avoids the label strip from wrinkling during the insertion process.

[0044] As Figures 1 to 8As shown in the figure, the feeding device 20 is arranged downstream of the driving roller 13 and includes a feeding table 21, a stop bar 22, a guiding bar 23, a pressing plate 24 and two retaining bars 25. The feeding table 21 is located downstream of the unwinding rack 11. The stop bar 22, the guiding bar 23 and the driving roller 13 are arranged in parallel. The stop bar 22 is installed at the starting side of the feeding table 21 and is used to prevent the label strip between the guiding bar 23 and the driving roller 13 from turning over and stacking, resulting in wrinkles in the local area of the label strip. The guiding bar 23 is installed on the feeding table 21 and is located above the stop bar 22. The pressing plate 24 is arranged downstream of the guiding bar 23 and is detachably installed on the top of the feeding table 21. The pressing plate 24 extends along the width direction of the label strip. In this embodiment, the label strip transmitted by the friction between the driving roller 13 and the driven roller 14 first passes through the notch on the stop bar 22 from bottom to top, then bypasses from the top of the guiding bar 23, and flows to between the feeding table 21 and the pressing plate 24. The pressing plate 24 presses the label strip below it flat. The retaining bars 25 are arranged downstream of the pressing plate 24 and are assembled on the top of the feeding table 21. The two retaining bars 25 are distributed on both sides of the label strip, thereby effectively limiting both sides of the label strip.

[0045] In this embodiment, the feeding table 21 is placed on the ground, and the unwinding rack 11 is fixed at the starting end of the feeding table 21.

[0046] In this embodiment, connection protrusions are respectively arranged at both ends of the bottom of the pressing plate 24, and connection grooves are arranged on the feeding table 21. The positions of the connection protrusions are matched with the positions of the connection grooves. The pressing plate 24 is detachably connected to the feeding table 21 through the cooperation of the connection protrusions and the connection grooves. A handle is arranged on the top of the pressing plate 24 for the staff to pick up and place the pressing plate 24.

[0047] Further, in order to adapt to label strips of different widths, the retaining bars 25 are slidably assembled on the feeding table 21, and long strip holes 251 are formed in the retaining bars 25. Locking screws 252 are assembled in the long strip holes 251. The long strip holes 251 extend along the width direction of the label strip. The locking screws 252 pass through the long strip holes 251 and are threadedly connected to the feeding table 21. When the position of the retaining bar 25 needs to be adjusted, loosen the locking screw 252, adjust the position of the retaining bar 25, and after the position is adjusted, tighten the locking screw 252 to fasten the retaining bar 25 on the feeding table 21.

[0048] Further, as Figure 8 shown, two limiting sliding sleeves 26 are arranged on the guiding bar 23. The limiting sliding sleeves 26 are slidably assembled on the guiding bar 23 and are distributed on both sides of the label strip, thereby effectively limiting both sides of the label strip. Tightening screws are arranged on the limiting sliding sleeves 26. The limiting sliding sleeves 26 are tightly fixed to the guiding bar 23 through the tightening screws. When the position of the limiting sliding sleeve 26 needs to be adjusted, loosen the tightening screw, adjust the position of the limiting sliding sleeve 26, and after the position is adjusted, tighten the tightening screw.

[0049] As shown Figures 1 to 3 in the figure, the ultrasonic cutter device 30 is arranged downstream of the stop bar 25 and sequentially includes a sensor 31, a feeding roller 32, a feeding motor, an ultrasonic cutter 33 and a baffle 34 along the conveying direction of the label strip. The sensor 31 is installed on the feeding port side of the ultrasonic cutter 33 and above the feeding table 21, and is used to monitor the identification points on the label strip on the feeding table 21 in real time. The feeding roller 32 is arranged downstream of the sensor 31 and assembled at the feeding port of the ultrasonic cutter 33, and is used to convey the label strip below the sensor 31 so that the label strip flows to the ultrasonic cutter 33. The driving end of the feeding motor is connected to the feeding roller 32 and is used to drive the feeding roller 32 to rotate. The ultrasonic cutter 33 is used to cut the label strip into sections of labels. The baffle 34 is arranged in the upper middle part of the discharge port of the ultrasonic cutter 33 to prevent the labels discharged from the discharge port of the ultrasonic cutter 33 from rising upward and avoid the labels from scattering everywhere.

[0050] In this embodiment, the sensor 31 is a vision sensor.

[0051] Among them, the sensor 31, the feeding motor, the ultrasonic cutter 33 and the unwinding motor 15 are respectively connected to the controller. Specifically, the sensor 31 detects the identification points on the label strip on the feeding table 21 and transmits the monitored signal to the controller; the controller analyzes according to the received signal and controls the ultrasonic slicing machine to feed or slice according to the specific position of the identification points on the label strip. When the controller controls the ultrasonic slicing machine to slice, the controller controls the feeding motor and the unwinding motor 15 to stop running and controls the ultrasonic cutter 33 to work to cut the label strip. When the controller controls the ultrasonic slicing machine to feed, the controller controls the feeding motor and the unwinding motor 15 to run and controls the ultrasonic cutter 33 to stop working. The controller synchronously controls the feeding motor, the ultrasonic cutter 33 and the unwinding motor 15 to ensure that the ultrasonic slicing machine works continuously without interruption, thereby ensuring that the label strip between the feeding device 20 and the unwinding device 10 will not accumulate together.

[0052] As shown Figures 1 to 3 in the figure, the discharging device 40 is arranged at the discharging port of the ultrasonic cutter 33 and sequentially includes a conveyor belt 41, a guide chute 42 and a receiving frame 43 along the conveying direction of the label. The conveyor belt 41 is arranged at the discharging port of the ultrasonic cutter 33. The guide chute 42 is arranged at the end of the conveyor belt 41. In this embodiment, the end of the guide chute 42 is arranged to incline downward. The receiving frame 43 is placed below the end of the guide chute 42 and is used to receive the labels discharged from the guide chute 42.

[0053] Furthermore, the receiving frame 43 is made of metal with good electrical conductivity, which can effectively eliminate the static electricity on the labels and avoid the labels from adsorbing dust during storage.

[0054] Further, the material guiding chute 42 can also be made of a metal with good electrical conductivity to eliminate static electricity on the labels.

[0055] Further, the discharging device 40 further includes a weight sensing device and a warning device. The weight sensing device is disposed at the bottom of the material receiving frame 43 for monitoring the weight of the material receiving frame 43. The weight sensing device and the warning device are respectively connected to the controller. The weight sensing device transmits the monitored signal to the controller, and the controller determines whether the material receiving frame 43 is full of labels according to the received signal. If the controller determines that the material receiving frame 43 is full of labels, then the controller controls the warning device to give a warning to prompt the staff to replace the empty material receiving frame 43.
