Description

Technical Field

[0001] This utility model relates to the field of plastic packaging sealing technology, and in particular to a plastic packaging sealing device. Background Technology

[0002] Plastic packaging bags are packaging bags made of plastic as raw material, used in the production of various daily necessities. They are widely used in daily life and industrial production, and sealing is also required during the plastic packaging process.

[0003] Existing plastic packaging sealing devices generally do not have limiting components for packaging bags being transported on the conveyor belt, which makes the packaging bags prone to shifting or falling during the sealing process, affecting subsequent sealing. Furthermore, there are no components to assist in moving the packaging bags to close the opening when sealing them, resulting in relatively loose openings and larger wrinkles when sealing the packaging bags later, reducing the practicality of the device.

[0004] Therefore, it is necessary to provide a plastic packaging sealing device to solve the above-mentioned technical problems. Utility Model Content

[0013] Preferably, the two U-shaped brackets are respectively fixedly connected to the base.

[0014] Preferably, one side of one of the U-shaped brackets is fixedly connected to the controller.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows: According to the size of the packaging bag to be sealed, the limiting module enables two limiting channels to limit the packaging bag, which can prevent the packaging bag from shifting during the sealing process.

[0036] The auxiliary moving closing module 1 includes two pairs of auxiliary pulleys 13, which are connected by corresponding auxiliary belts 14. The central shafts of the two pairs of auxiliary pulleys 13 pass through and are movably connected to the horizontal plate 3.

The output shaft of motor 11 is fixedly connected to the center of one of the gears 15. Motor 11 is fixedly connected to U-shaped connecting plate 12. U-shaped connecting plate 12 is fixedly connected to the horizontal plate 3.

[0037] The transport component 6 includes a transport bracket 62, which is fixedly connected to the base 7. A second motor 61 is fixedly connected to one side of the transport bracket 62. The output shaft of the second motor 61 passes through one side of the transport bracket 62. The end of the output shaft of the second motor 61 is fixedly connected to one of the transmission rollers of the transport component 6. The transport speed of the transport conveyor belt of the transport component 6 is the same as the transport speed of the auxiliary belt 14.

[0038] The limiting module 9 includes a lead screw groove 93, which is fixedly connected to the base 7. Two sliders 94 are provided within the lead screw groove 93. The upper sides of the two sliders 94 are respectively fixedly connected to corresponding L-shaped clamps 92. The two L-shaped clamps 92 are respectively fixedly connected to corresponding limiting channels 91. One end of a bidirectional lead screw 95 is movably connected to the inner two ends of the lead screw groove 93. The two ends of the bidirectional lead screw 95 are respectively provided with two sections of threads with opposite directions. The bidirectional lead screw 95 is threadedly connected to the corresponding sliders 94. One end of the bidirectional lead screw 95 passes through one end of the lead screw groove 93, and the end of the bidirectional lead screw 95 is fixedly connected to the center of a knob 96.

[0039] The two ends of the horizontal plate 3 are respectively fixedly connected to the corresponding U-shaped brackets 4.

[0040] The two U-shaped brackets 4 are respectively fixedly connected to the base 7.

[0041] The controller 8 is fixedly connected to one side of one of the U-shaped brackets 4.

[0042] The controller 8 is electrically connected to motor 11, motor 261, through-beam sensor 28 and electric push rod 22 respectively.

[0043] Working principle: First, place the packaging bag 5 to be sealed on the conveyor belt of the transport component 6, so that the upper opening of the packaging bag 5 is between the two auxiliary belts 14. According to the size of the packaging bag 5 to be sealed, turn the knob 96. The knob 96 drives the bidirectional lead screw 95 to rotate. The bidirectional lead screw 95 drives the corresponding slider 94 to slide. The two sliders 94 drive the limiting channel 91 to move through the L-shaped clamp 92, so that the two limiting channels 91 limit the packaging bag 5 and prevent the packaging bag 5 from shifting during the sealing process. At this time, stop turning the knob 96.

[0044] Next, controller 8 starts motor 2 61 and motor 1 11. Motor 2 61 drives the transport assembly 6, causing the conveyor belt of the transport assembly 6 to move the packaging bag 5. At this time, motor 2 11 drives one gear 15 to rotate, and one gear 15 meshes with another gear 15 to rotate. The two gears 15 drive two auxiliary pulleys 13 to rotate, and the two auxiliary pulleys 13 drive two other auxiliary pulleys 13 to rotate through auxiliary belts 14. The two auxiliary belts 14 assist the movement of the packaging bag 5, and can pinch and smooth the opening of the packaging bag 5 to reduce wrinkles at the opening of the packaging bag 5. When the packaging bag 5 moves between the two through-beam sensors 28, the light emitted by the through-beam sensors 28 is blocked. At this time, the packaging bag 5 is between the two heat-sealing plates 24, and the through-beam sensors 28 are blocked. Sensor 28 sends a signal to controller 8, causing controller 8 to shut down motor 21 and motor 11, and start electric push rod 22. The telescopic rod of electric push rod 22 retracts, causing connecting rod 21 to swing. The two connecting rods 21 respectively drive cross-shaped slider 26 to slide along cross-shaped groove 29, causing cross-shaped slider 26 to move L-shaped rod 23, through-beam sensor 28, heat sealing plate 24, etc., through connecting plate 25, so that the two heat sealing plates 24 seal the opening of packaging bag 5. At this time, the sealing operation of packaging bag 5 is completed. After sealing, controller 8 controls the telescopic rod of electric push rod 22 to extend, heat sealing plate 24 is removed from packaging bag 5, and starts control motor 21 and motor 11. Packaging bag 5 is moved out from the other end of the conveyor belt of transport component 6, completing the sealing operation.

[0045] Beneficial effects: Based on the size of the packaging bag 5 to be sealed, the limiting module 9 enables the two limiting channels 91 to limit the packaging bag 5, which can prevent the packaging bag 5 from shifting during the sealing process. The transportation module 6 transports the packaging bag, and the auxiliary moving closing module 1 enables the two auxiliary belts 14 to assist the movement of the packaging bag 5, which can pinch the opening of the packaging bag 5 to reduce the wrinkles at the opening of the packaging bag 5. When the packaging bag 5 moves between the two photoelectric sensors 28, the light emitted by the photoelectric sensors 28 is blocked, and finally the two heat sealing plates 24 seal the opening of the packaging bag 5.
