Description
Technical Field
[0001] This utility model relates to the field of flame retardant production technology, and more specifically, to a vacuum packaging machine for halogen-free flame retardants. Background Technology
[0002] Halogen-free flame retardants are non-toxic, non-corrosive, and environmentally friendly flame-retardant materials with low smoke emission, high oxygen index, and excellent flame retardancy. They are primarily used for flame-retardant treatment of wires and cables, and can also be used for fire protection of electronic components and precision instruments. Furthermore, halogen-free flame retardants can be applied to the insulation layers of automotive wiring harnesses, fireproof and thermal insulation systems in building materials, wiring connections in household appliances, and the connecting wires between computer motherboards and monitors, demonstrating their wide range of applications.
[0003] Although halogen-free flame retardants have good flame retardant properties, during transportation, oxygen in the air will come into contact with the flame retardant and cause an oxidation reaction, which will reduce its flame retardant effect. In addition, moisture and impurities in the outside air will also affect the quality of the flame retardant. Therefore, vacuum packaging is required.
[0004] Currently, vacuum packaging machines use a vacuum pump to extract air from the packaging bag to create a vacuum. Once the set vacuum level is reached, the control system shuts off the vacuum pump and sends a signal to activate the heat-sealing mechanism, which heat-seals the opening of the packaging bag. However, before heat-sealing, workers fix the packaging bag containing flame retardant onto the packaging machine. Due to gravity, the flame retardant powder tends to accumulate at the bottom of the bag, making vacuum packaging bulky. The flame retardant needs to be evenly distributed inside the bag, thus requiring improvement and optimization. Utility Model Content

[0009] As a preferred technical solution of this utility model, a fixing plate is fixedly installed on one side of each of the two sets of heat insulation bases, and a fixing rod is fixedly installed on both the left and right sides of each of the two sets of fixing plates.
[0010] As a preferred embodiment of this utility model, a movable block is movably sleeved inside the fixed rod, and a pressure roller is rotatably installed between the two sets of movable blocks.
[0011] In a preferred embodiment of this invention, the moving block and the fixed rod are elastically connected by a first spring, the pressure roller and the fixed plate abut against each other, and the pressure roller is used to fix the packaging bag.
[0012] As a preferred embodiment of this utility model, a guide rod is fixedly installed inside the limiting groove, and the guide rod and the vibration plate are movably connected.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] like Figures 1 to 7 As shown, this utility model provides a vacuum packaging machine for halogen-free flame retardants, including a machine body 1, a packaging platform 2 fixedly installed on the top of the machine body 1, a vacuum sealing cover 3 provided on the top of the packaging platform 2, and a support platform 4 provided on both the left and right sides of the top of the packaging platform 2.
[0030] Heat-insulating bases 5 are fixedly installed on both the front and rear sides of the bearing platform 4. A vibration chamber 11 is opened inside the body 1. Limiting grooves 13 are opened on both the front and rear sides of the vibration chamber 11. A vibration plate 12 is movably installed inside the limiting groove 13. A connecting block 16 is fixedly installed at the bottom of the vibration plate 12. A first vibration rod 17 is rotatably installed inside the vibration chamber 11. A second vibration rod 19 is rotatably installed inside the vibration chamber 11. A rotating rod 18 is rotatably installed inside the connecting block 16. One end of the second vibration rod 19 passes through the rotating rod 18 and is fixedly connected to the first vibration rod 17. A first motor 20 is fixedly installed on the outer wall of the body 1. The output shaft of the first motor 20 passes through the inside of the vibration chamber 11 and is fixedly connected to the second vibration rod 19.
[0031] When packaging halogen-free flame retardants, the worker first fills the flame retardant product into the packaging bag. Due to gravity, the flame retardant accumulates at the bottom of the bag. The worker then places the bag containing the product inside the support platform 4, ensuring it is on top of the vibrating plate 12. Next, the worker lifts the pressure roller 9 upwards. At this time, the moving block 8 lifts upwards along the fixed rod 7, and the first spring 10 is compressed. The worker passes one end of the bag opening through the bottom of the pressure roller 9 and places it on top of the heat-insulating base 5. Then, the worker releases the pressure roller 9. The elastic potential energy of the first spring 10 drives the moving block 8 and the pressure roller 9 downwards, clamping the opening of the packaging bag. The worker then starts the first motor 20. The operation of the first motor 20 drives the second vibrating rod 19 to rotate. Since one end of the second vibrating rod 19 passes through the rotating rod 18 and is fixedly connected to the first vibrating rod 17, the second... The vibrating rod 19 and the first vibrating rod 17 synchronously drive the rotating rod 18 to move. However, the rotating rod 18 and the vibrating plate 12 are connected by the connecting block 16, and the moving path of the vibrating plate 12 is restricted by the limiting groove 13, so that the vibrating plate 12 can only move up and down. As the second vibrating rod 19 rotates, the vibrating plate 12 begins to vibrate, thereby dispersing the flame retardant inside the packaging bag at the top of the vibrating plate 12 and distributing it evenly inside the packaging bag. Then, the operator pulls the vacuum sealing cover 3 to seal the carrier platform 4 and controls the machine to perform vacuum suction. After suction is completed, the heat sealing mechanism inside the vacuum sealing cover 3 will seal the opening of the packaging bag to complete the packaging. It is worth noting that the heat sealing mechanism is built into the vacuum sealing cover 3 and is existing technology. The heat insulation base 5 is set to prevent the high temperature caused by heat sealing from damaging the carrier platform 4.
[0032] The elastic potential energy of the first spring 10 fixes the packaging bag to the pressure roller 9 and the fixed plate 6. The operation of the first motor 20 causes the second vibrating rod 19 and the first vibrating rod 17 to rotate synchronously. The further rotating rod 18 drives the vibrating plate 12 to move up and down along the guide rod 14, thereby dispersing the powder inside the packaging bag. Compared with traditional devices, this device can disperse the flame retardant product inside the packaging bag before the halogen-free flame retardant is packaged, so that it is evenly distributed inside the packaging bag, improving the packaging quality and reducing the workload of the staff.
[0033] The machine body 1 has a movable base plate 23 installed inside, and a lead screw 25 is rotatably installed inside the machine body 1. The lead screw 25 and the movable base plate 23 are threaded together. The four corners of the bottom of the movable base plate 23 are provided with casters 24. The machine body 1 has a transmission chamber 26 inside, and a worm gear 27 is rotatably installed inside the transmission chamber 26. The worm gear 27 and the lead screw 25 are fixedly connected.
[0034] During prolonged operation, dust and impurities accumulate inside the casters 24, impairing their mobility. Therefore, they are stored inside the body 1. When the body 1 needs to be moved or transported, the operator starts the second motor 28. The output shaft of the second motor 28 drives the worm gear 29 to rotate. The rotation of the worm gear 29 drives the worm wheel 27 to rotate, which in turn drives the lead screw 25 to rotate. The rotation of the lead screw 25 causes the movable base plate 23, which is threadedly connected to it, to move downwards. After the movable base plate 23 moves to the bottom, the four sets of casters 24 move to the bottom of the body 1 through the telescopic groove 22 and support the body 1.
[0035] By retracting the casters 24 into the interior of the machine body 1, the accumulation of impurities inside the casters 24 prevents movement malfunction. The operation of the second motor 28 causes the lead screw 25 to rotate, driving the movable base plate 23, which is threadedly connected to it, to move downward, further supporting the machine body 1 with the casters 24. Compared with traditional devices, this device not only protects the casters 24, but also reduces noise by providing shock absorption and anti-slip for the machine body 1 through the presence of four sets of anti-slip pads 21.
[0036] Among them, a fixing plate 6 is fixedly installed on one side of each of the two sets of heat insulation bases 5, and a fixing rod 7 is fixedly installed on both the left and right sides of each of the two sets of fixing plates 6.
[0037] The fixed rod 7 is responsible for guiding the moving block 8 to prevent the pressure roller 9 from shifting or becoming misaligned.
[0038] The fixed rod 7 has a movable sleeve of a moving block 8 inside, and a pressure roller 9 is rotatably installed between the two sets of moving blocks 8.
[0039] The movable block 8 and the fixed rod 7 are elastically connected by a first spring 10, and the pressure roller 9 and the fixed plate 6 abut against each other. The pressure roller 9 is used to fix the packaging bag.
[0040] When the packaging bag is fixed, the pressure roller 9 clamps the packaging bag by the elastic potential energy of the first spring 10.
[0041] The guide rod 14 is fixedly installed inside the limiting groove 13, and the guide rod 14 and the vibration plate 12 are movably connected.
[0042] The guide rod 14 is provided with a second spring 15 on its outer wall. The vibrating plate 12 and the limiting groove 13 are elastically connected by the second spring 15, and the tops of the vibrating plate 12 and the limiting groove 13 abut against each other.
[0043] The limiting groove 13 and the guide rod 14 are responsible for the misalignment of the vibrating plate 12 and play a guiding role. After the vibrating plate 12 stops vibrating, the second spring 15 will drive the vibrating plate 12 to return to its original position.
[0044] Two sets of hinge rods 30 are rotatably installed on both the front and rear sides of the outer wall of the packaging platform 2, and the other end of each hinge rod 30 is rotatably connected to the vacuum sealing cover 3.
[0045] Anti-slip pads 21 are fixedly installed at the four corners of the bottom of the body 1, and telescopic grooves 22 are opened on the left and right sides of the bottom of the body 1.
[0046] Four sets of anti-slip pads 21 are used for shock absorption and anti-slip of the body 1.
[0047] The transmission chamber 26 contains a second motor 28, whose output shaft is fixedly connected to a worm gear 29. The worm gear 29 is rotatably mounted inside the transmission chamber 26 and is connected to a worm wheel 27.
[0048] The staff started the second motor 28. The output shaft of the second motor 28 drove the worm 29 to rotate. The rotation of the worm 29 drove the worm wheel 27 to rotate, and further drove the lead screw 25 to rotate.
[0049] Working principle and usage process of this utility model:
[0050] When packaging halogen-free flame retardants, the worker first fills the flame retardant product into the packaging bag. Due to gravity, the flame retardant accumulates at the bottom of the bag. The worker then places the bag containing the product inside the support platform 4, ensuring it is on top of the vibrating plate 12. Next, the worker lifts the pressure roller 9 upwards. At this time, the moving block 8 lifts upwards along the fixed rod 7, and the first spring 10 is compressed. The worker passes one end of the bag opening through the bottom of the pressure roller 9 and places it on top of the heat-insulating base 5. Then, the worker releases the pressure roller 9. The elastic potential energy of the first spring 10 drives the moving block 8 and the pressure roller 9 downwards, clamping the opening of the packaging bag. The worker then starts the first motor 20. The operation of the first motor 20 drives the second vibrating rod 19 to rotate. Since one end of the second vibrating rod 19 passes through the rotating rod 18 and is fixedly connected to the first vibrating rod 17, the second... The vibrating rod 19 and the first vibrating rod 17 synchronously drive the rotating rod 18 to move. However, the rotating rod 18 and the vibrating plate 12 are connected by the connecting block 16, and the moving path of the vibrating plate 12 is restricted by the limiting groove 13, so that the vibrating plate 12 can only move up and down. As the second vibrating rod 19 rotates, the vibrating plate 12 begins to vibrate, thereby dispersing the flame retardant inside the packaging bag at the top of the vibrating plate 12 and distributing it evenly inside the packaging bag. Then, the operator pulls the vacuum sealing cover 3 to seal the carrier platform 4 and controls the machine to perform vacuum suction. After suction is completed, the heat sealing mechanism inside the vacuum sealing cover 3 will seal the opening of the packaging bag to complete the packaging. It is worth noting that the heat sealing mechanism is built into the vacuum sealing cover 3 and is existing technology. The heat insulation base 5 is set to prevent the high temperature caused by heat sealing from damaging the carrier platform 4.
