Description

Technical Field

[0001] This utility model relates to an improved invention of a bag packaging machine, and more particularly to an improved invention of an ultrasonic sealing mechanism for a bag packaging machine. Background Technology

[0002] Existing pre-packaged bag machines generally use resistance heating heat sealing mechanisms, which have the following drawbacks: reliance on continuous high-temperature heat conduction results in low efficiency and high energy consumption; they are prone to damaging heat-sensitive materials (such as PET and biodegradable films); the sealing pass rate is ≤90%; and there is a risk of air leakage. This invention aims to improve ultrasonic sealing equipment to be suitable for pre-packaged bag machines, achieving seamless sealing and bag feeding, reducing vibration loss, and ensuring packaging quality and efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an ultrasonic sealing mechanism for a bag packaging machine.

Its features include: a column, a carrier at the upper end of the column, an ultrasonic generator, a transducer, a welding head, a pressing mold, and a control system on the carrier; the welding head is connected to the transducer, and the transducer is connected to the ultrasonic generator; the transducer is mounted on a first mounting base, and the pressing mold is mounted on a second mounting base; the first and second mounting bases are movably mounted on a linear guide rail; the first and second mounting bases are respectively equipped with a first cylinder and a second cylinder; the corresponding welding head is welded to the pressing mold; and air nozzles are respectively mounted above and below the welding head, corresponding to the sealing of the packaging bag; the first cylinder, the second cylinder, and the air nozzles are connected to an air source and equipped with a solenoid valve, which is connected to the control system.

[0005] The carrier includes a base plate, a left side plate, a right side plate, a rear side plate, a front baffle, and an upper cover plate that form an installation cavity. An opening is provided on the front side of the installation cavity, and the corresponding welding head and pressure mold work outside the opening.

[0006] The ultrasonic generator is located at the upper end of the upper cover plate, and a pad is provided between the ultrasonic generator and the upper cover plate.

[0007] A fan is provided on the inner side of the rear panel, and the fan corresponds to the transducer.

[0009] The beneficial effect of this utility model is that the improved ultrasonic sealing mechanism of the bag packaging machine is connected to the outer circumference of the turntable of the bag packaging machine. The control system controls the first cylinder and the second cylinder, which in turn drives the welding head and the pressure mold to seal the packaged bags in real time and quickly, reducing the loss of air vibration and ensuring packaging quality and packaging efficiency.

[0013] Figure 3 This is a diagram showing the combination of this utility model and the turntable. Detailed Implementation

[0014] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-3 The ultrasonic sealing mechanism of the bag packaging machine is located at the sealing station on the outer periphery of the turntable of the bag packaging machine. It includes a column 1, with a carrier 2 at the upper end of the column 1. The carrier 2 houses an ultrasonic generator 3, a transducer 4, a welding head 5, a pressing mold 6, and a control system. The welding head 5 is connected to the transducer 4, and the transducer 4 is connected to the ultrasonic generator 3. The transducer 4 is mounted on a first mounting base 7, and the pressing mold 6 is mounted on a second mounting base 8. The first mounting base 7 and the second mounting base 8 are connected. The slider is movable on the linear guide rail 9, and the first mounting base 7 and the second mounting base 8 are respectively equipped with the first cylinder 10 and the second cylinder 11. The corresponding welding head 5 is welded to the mold 6, and the welding head 5 is equipped with the air blowing nozzle 12 above and below it. The air blowing nozzle 12 is arranged at an angle to seal the packaging bag. The first cylinder 10, the second cylinder 11 and the air blowing nozzle 12 are connected to an air source and are equipped with a solenoid valve 13. The solenoid valve 13 is connected to the control system, which is preferably a PLC.

[0015] The working principle of this utility model is as follows: the ultrasonic generator 3 serves as the power supply module, adjusting the transmission power and frequency to ensure stable transmission of vibration energy to the welding area. The transducer 4 converts electrical energy into high-frequency mechanical vibration. The welding head 5 transmits ultrasonic energy to the sealing area. The pressure mold 6, in conjunction with the welding head 5, generates heat through contact friction to seal the packaging bag. The welding head 5 and the pressure mold 6 move towards each other along the linear guide rail 9, respectively, with the first mounting base 7 and the second mounting base 8, driven by the first cylinder 10 and the second cylinder 11, to weld together. After the packaging bag is sealed, the air nozzle 12 rapidly cools and solidifies the hot-pressed packaging bag seal. The air source for the first cylinder 10, the second cylinder 11, and the air nozzle 12 is supplied by the control system controlled by the solenoid valve 13.

[0016] As a further improved specific implementation, the carrier 2 includes a base plate 14, a left side plate 15, a right side plate 16, a rear side plate 17, a front baffle 18, and an upper cover plate 19 that form an installation cavity. The installation cavity has an opening on the front side, and the corresponding welding head 5 and the pressure mold 6 work outside the opening to cooperate with the sealing of the packaging bag. The transducer 4, the first mounting seat 7, the first cylinder 10, the solenoid valve 13, etc. are set inside the installation cavity, the pressure mold 6, the second mounting seat 8, the second cylinder 11 are set outside the installation cavity, and the linear guide rail 9 is set on the inner side of the upper cover plate 19, spanning the inside and outside of the installation cavity.

[0017] As a further improved specific implementation, the ultrasonic generator 3 is disposed on the upper end of the upper cover plate 19, and a pad 20 is provided between the ultrasonic generator 3 and the upper cover plate, the pad serving a fixing function.

[0018] As a further improved specific implementation, a fan 21 is provided on the inner side of the rear panel 17. The fan 21 corresponds to the transducer and dissipates heat from the mounting cavity to reduce the temperature of the equipment's working environment.

[0019] As a further improvement, the sealing action of the sealing mechanism is connected with the bag transfer action of the bag-feeding packaging machine to reduce the vibration loss of the sealing mechanism.

[0020] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
