[0018] Combined with Figures 1 to 3 As shown, a rolling sealing and trimming device includes a transverse sealing part 1 and a longitudinal sealing part 2. The transverse sealing part 1 includes ultrasonic welding rollers 10 and a pressure roller 11 that roll towards each other. A plurality of mounting grooves 12 are provided on the outer periphery of the pressure roller 11. A pressure block 3 is detachably provided in the mounting groove 12. A transverse cutting edge 31 is provided at the top of the pressure block 3. Transverse pressing surfaces 32 are respectively provided on both sides of the transverse cutting edge 31. A transverse pressing gap 100 is provided between the ultrasonic welding rollers 10 and the pressure roller 11.

[0019] A wedge-shaped positioning part 33 is provided on the side of the pressure block 3 away from the transverse cutting edge 31. A wedge-shaped groove 120 is provided at a position corresponding to the wedge-shaped positioning part 33 in the mounting groove 12. A mounting hole 30 is provided on the other side of the transverse cutting edge 31. A bolt 4 is inserted through the mounting hole 30, and the bolt 4 presses the pressure block 3 tightly in the mounting groove 12 of the pressure roller 11.

[0020] The longitudinal sealing part 2 includes ultrasonic welding pads 20 and a pressure plate 21 that roll towards each other. A longitudinal cutting edge 211 is provided on the outer periphery of the pressure plate 21. Longitudinal pressing surfaces 212 are respectively provided on both sides of the longitudinal cutting edge 211. A longitudinal pressing gap 200 is provided between the ultrasonic welding pads 20 and the pressure plate 21.

[0021] In use, the ultrasonic welding roller 10 and the ultrasonic welding pad 20 are respectively connected to transducers. The transducers convert the high-frequency alternating current generated by the set ultrasonic generator into vibrations of the same frequency, and then drive the ultrasonic welding roller 10 and the ultrasonic welding pad 20 to vibrate respectively. Ultrasonic welding and cutting are carried out simultaneously. The frequency used by the ultrasonic generator can be in the range of 20 kHz to 45 kHz, and the power can be in the range of 100 watts to 300 watts. The longitudinal connection of the packaging bag combined into a cylindrical shape is passed through the longitudinal crimping gap 200. In the longitudinal sealing part 2, the pressing plate 21 in the radial direction presses towards the side of the ultrasonic welding pad 20. The vibration of the ultrasonic welding pad 20 is transmitted to the pressing plate 21, causing high-frequency vibration at the sealing part of the packaging bag, so that the temperature of the bag mouth rises and melts and adheres, and the longitudinal edge of the package is cut through the set longitudinal cutting edge 211.

[0022] In the transverse sealing part 1, the ultrasonic welding roller 10 transmits high-frequency vibration to the bag mouth of the packaging bag clamped by the ultrasonic welding roller 10 and the pressing roller 11, causing high-frequency vibration at the sealing part of the packaging bag, so that the temperature of the bag mouth rises and melts and adheres, and the cutting of the package is achieved through the set transverse cutting edge 31. When it is necessary to intercept packaging bags of different lengths and sizes, the distance can be adjusted by adjusting the number of the pressing blocks 3 in the pressing roller 11; when disassembling the pressing block 3, only the bolts 4 on one side need to be disassembled, and the reliable fixation of the pressing block 3 is achieved through the cooperation of the bolts 4 and the wedge-shaped positioning part 33. The cooperation between the longitudinal sealing part 2 and the transverse sealing part 1 realizes continuous welding of the bag mouth of the packaging bag, which not only reduces the production cost without preheating, but also reduces the probability of powder leakage at the bag mouth and improves the welding quality of the seal.
