Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1 to 2 The sealing device for packaging ice-boron powder in this embodiment includes a conveyor belt 1. Support feet 2 are provided on both the left and right sides of the lower surface of the conveyor belt 1. Several limiting frames 3 are provided on the outer side of the conveyor belt 1. A support frame 4 is fixed to the back of the conveyor belt 1 by bolts. A sealing component 5 is provided on the upper surface of the support frame 4. A filter component 6 is provided on the right side of the upper surface of the support frame 4. The limiting frames 3 are rubber frames that can deform.
[0019] Please see Figure 3In this embodiment, the sealing assembly 5 includes an electric push rod 501 fixed to the upper surface of the support frame 4. The outer side of the output shaft of the electric push rod 501 slides through the support frame 4 and extends into it. A rectangular frame 502 is fixed to the outer side of the output shaft of the electric push rod 501. A threaded rod 503 is rotatably connected to the inside of the rectangular frame 502 through a bearing. A motor 504 is fixed to the right side of the rectangular frame 502. The right side of the threaded rod 503 rotatably passes through the rectangular frame 502 and is fixedly connected to the outer side of the output shaft of the motor 504. Two moving blocks 505 are threadedly connected to the outer side of the threaded rod 503. A photoelectric sensor 506 is fixed to the lower surface of the rectangular frame 502. Connectors are provided on the lower surfaces of the moving blocks 505 on the left and right sides.
[0020] Specifically, the packaging bags containing ice-boron powder can be placed sequentially inside several limiting frames 3 with the sealed end facing upwards. By starting the equipment, the conveyor belt 1 transports the packaging bags to the right. When the packaging bags are transported to below the sealing assembly 5, the photoelectric sensor 506 detects the position of the packaging bags and sends a signal to the main controller. After receiving the signal from the photoelectric sensor 506, the main controller starts the electric push rod 501, the conveyor belt 1 stops transporting, and the output shaft of the electric push rod 501 extends downwards, driving the rectangular frame 502 to move downwards.
[0021] Specifically, the connector includes a connecting plate 507 fixed to the lower surface of the left and right movable blocks 505. A spring telescopic rod 508 is fixed to the opposite side of each of the left and right connecting plates 507. A mounting plate 509 is fixed to the opposite side of each of the left and right spring telescopic rods 508. A heating plate 510 is fixed to the opposite side of each of the left and right mounting plates 509. The left and right movable blocks 505 are slidably connected to the inside of the rectangular frame 502. Sliding openings are provided on the left and right sides of the lower surface of the rectangular frame 502. The left and right connecting plates 507 are slidably connected to the inside of the sliding openings on the left and right sides. The spring telescopic rod 508 includes a first sliding rod. A second sliding rod is slidably connected inside the first sliding rod. A spring is movably fitted on the outside of the first sliding rod.
[0022] It should be noted that after the heating plates 510 on both sides are lowered to the sealing position of the packaging bag, the motor 504 starts and drives the threaded rod 503 to rotate. The heating plates 510 on both sides move in opposite directions. When the heating plates 510 on both sides move to the sealing position of the packaging bag, the spring telescopic rods 508 on both sides are compressed, generating elastic force, so that the heating plates 510 are tightly attached to the packaging bag. The heating plates 510 are heated by electricity, and the sealing part of the packaging bag is hot-pressed, so that the sealing material of the packaging bag melts and sticks together, completing the sealing. After the sealing is completed, the output shaft of the electric push rod 501 retracts, driving the sealing assembly 5 to rise and reset. The motor 504 reverses, causing the two heating plates 510 to separate, and the conveyor belt 1 continues to transport the next packaging bag, repeating the above process.
[0023] It should be noted that the application of photoelectric sensor 506 enables automatic detection of the packaging bag position. Combined with electric push rod 501 and motor 504, the entire sealing process is automated, reducing manual intervention and improving production efficiency.
[0024] Please see Figure 4 In this embodiment, the filter assembly 6 includes a filter frame 601 fixed to the right side of the upper surface of the support frame 4. A guide bucket 602 is connected to the left side of the filter frame 601. An annular tube 603 is provided on the lower surface of the rectangular frame 502. Several air inlets are connected to the lower surface of the annular tube 603. A filter screen is fixed inside each of the several air inlets. The left side of the guide bucket 602 passes through the support frame 4 through a movable tube and is connected to the back of the annular tube 603. A fan 604 is fixed to the upper surface of the filter frame 601. The air inlet of the fan 604 is connected to the upper surface of the filter frame 601 through a pipe. The movable tube can deform, and its length can control the up and down movement of the heating plate 510. Several heating wires are provided inside the heating plate 510, which can make the heating plate 510 heat up.
[0025] Specifically, the filter assembly 6 also includes a sealing plate 605 fixed to the right side of the filter frame 601 by bolts. Limiting blocks 606 are fixed to the bottom and top walls of the inner cavity of the filter frame 601. An installation frame 607 is fixed to the right side of the upper and lower limiting blocks 606 by bolts. A rubber sealing ring is fixed to the outside of the installation frame 607. The outside of the rubber sealing ring is in contact with the inner peripheral wall of the filter frame 601. An activated carbon filter screen 608 is fixed inside the installation frame 607. The outer diameter of the rubber sealing ring is adapted to the inner diameter of the filter frame 601. The sealing plate 605 includes a circular plate. A rubber ring is fixed to the left side of the circular plate. The left side of the rubber ring abuts against the right side of the filter frame 601.
[0026] It should be noted that the exhaust gas generated during the sealing process is drawn into the filter frame 601 by the fan 604 through the annular pipe 603 and the air inlet. After being adsorbed and filtered by the activated carbon filter 608, harmful substances are removed and discharged, reducing pollution to the environment. The device is equipped with a main controller.
[0027] It should be noted that all electrical components appearing in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing publicly available power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
[0028] The working principle of the above embodiments is as follows: In use, the packaging bags containing the ice-boron powder can be placed sequentially inside several limiting frames 3 with the sealed ends facing upwards. By starting the equipment, the conveyor belt 1 transports the packaging bags to the right. When the packaging bag is transported to below the sealing assembly 5, the photoelectric sensor 506 detects the position of the packaging bag and sends a signal to the main controller. After receiving the signal from the photoelectric sensor 506, the main controller starts the electric push rod 501, the conveyor belt 1 stops transporting, and the output shaft of the electric push rod 501 extends downwards, driving the rectangular frame 502 to move downwards, causing the heating plates 510 on both sides to descend to the sealing position of the packaging bag. Then, the motor 504 starts, driving the threaded rod 503 to rotate, causing the heating plates 510 on both sides to move in opposite directions. When the heating plate 510 moves to the sealing position of the packaging bag, the spring telescopic rods 508 on both sides are compressed, generating elastic force, which makes the heating plate 510 fit tightly against the packaging bag. The heating plate 510 is heated by electricity, which heats the sealing part of the packaging bag, causing the sealing material of the packaging bag to melt and stick together, thus completing the sealing. After the sealing is completed, the output shaft of the electric push rod 501 retracts, driving the sealing assembly 5 to rise and reset. The motor 504 reverses, causing the two heating plates 510 to separate. The conveyor belt 1 continues to transport the next packaging bag, repeating the above process. The exhaust gas generated during the sealing process is drawn into the filter frame 601 by the fan 604 through the annular pipe 603 and the suction nozzle. After being adsorbed and filtered by the activated carbon filter screen 608, harmful substances are removed and discharged, reducing pollution to the environment.
