Description

Technical Field

[0001] The invention belongs to the technical field of bubble bag packaging, in particular to a solvent-free composite aluminized film bubble bag packaging machine. Background Art

[0002] Aluminum film bubble bag is a composite packaging material that combines aluminum film and bubble film. It is mainly used for moisture-proof, heat-insulating, anti-static and buffering protection. Its structure is usually composed of an outer layer of aluminum film and an inner layer of bubble film. The aluminum film is made by vacuum-depositing an extremely thin metal aluminum layer on the surface of the plastic film. It has excellent gloss, high barrier properties and good heat reflection properties; the bubble film is blow-molded from polyethylene material, and is filled with uniform bubbles inside. It absorbs external impact force through the air cushioning principle to prevent the items inside from being damaged by vibration or extrusion. The solvent-free composite aluminum film bubble bag is an environmentally friendly packaging material produced by a solvent-free composite process on the basis of traditional aluminum film bubble bags, eliminating VOCs emissions and in line with the green packaging trend.

[0003] When using this type of bubble bag for packaging, the items to be packaged need to be placed in the unfolded bag body to ensure that the product is in contact with the bubble film layer to obtain cushioning protection, and then the high temperature and pressure generated by the heat sealing device are used to make the aluminum film at the bag opening tightly bonded to the bubble film to form a completely sealed packaging structure. However, in actual use, the bubble bag is usually rolled into a roller shape, and the bubble bag will gradually be consumed when the material is transported and packaged. The fixing structure of the traditional bubble bag winding roller lacks a convenient disassembly mechanism, and usually adopts bolt tightening or slot nesting. The operator needs to use tools such as wrenches and screwdrivers to repeatedly unscrew and disassemble. This process is time-consuming and labor-intensive, especially on a continuously operating production line. Frequent replacement of empty rolls significantly reduces packaging efficiency, so it needs to be improved and optimized. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 9 As shown, an embodiment of the present invention provides a solvent-free composite aluminized film bubble bag packaging machine, comprising a conveyor 1 and a packaging table 2, wherein the conveyor 1 is located on the left side of the packaging table 2, a conveyor belt 3 is provided at the bottom of the packaging table 2, a heating iron 5 is fixedly installed on the left wall of the packaging table 2, and a guide mechanism 4 is provided on the left and right sides of the heating iron 5, a heat sealing table 6 is fixedly installed in the middle of the packaging table 2, a cylinder 7 is fixedly installed on the top of the heat sealing table 6, the telescopic end of the cylinder 7 passes through the bottom of the heat sealing table 6 and is fixedly installed with a pressing plate 8, and a heat sealing head 9 is fixedly installed at the bottom of the pressing plate 8;

[0031] A rotating disk 11 is rotatably installed at the lower left of the packaging table 2, and a mounting roller 12 is fixedly installed on the front side of the rotating disk 11. A bidirectional screw 13 is rotatably installed inside the mounting roller 12. Guide grooves 15 are provided on the left and right sides of the outer surface of the mounting roller 12, and sliders 14 are movably installed on the front and back sides of the interior of the mounting roller 12. The two groups of sliders 14 are respectively threadedly connected to the front and back ends of the bidirectional screw 13, and the left and right ends of the two groups of sliders 14 are hinged with connecting rods 17, and one end of the left and right groups of connecting rods 17 is hinged with support plates 16. A winding drum 30 is provided on the outside of the mounting roller 12, and the two groups of support plates 16 fix the winding drum 30. A motor 18 is fixedly installed inside the rotating disk 11, and the output shaft of the motor 18 is fixedly connected to the bidirectional screw 13.

[0032] When it is necessary to use solvent-free composite aluminized film bubble bags to package materials, the staff first places the reel 30 for reeling in this type of bubble bag on the mounting roller 12, and then starts the motor 18. The operation of the motor 18 will drive the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 will drive the two sets of sliders 14 threadedly connected thereto to move. Furthermore, since the threads at the front and rear ends of the bidirectional screw 13 are opened in opposite directions, the two sets of sliders 14 are synchronously displaced inwardly along the guide groove 15. When the distance between the two sets of sliders 14 is shortened, since it is inconvenient to fix the length of the connecting rod 17, the connecting rod 17 will extend outward, and further the two sets of support plates 16 will move inwardly along the reel. The inner walls of 30 fit together to complete the fixation of the winding drum 30, and then the staff unfolds the bubble bag and lays it on the packaging table 2. At this time, the sealing part of the bubble bag will pass between the guide rollers of the two sets of guide mechanisms 4 in sequence, and when the bubble bag passes through the heated soldering iron 5, the top of the bubble bag will be heated and sealed. After the material is guided by the conveyor 1 and the feed plate 21 and transported to the conveyor belt 3, the material will enter the interior of the bubble bag and be further transported to the heat sealing table 6. At this time, the staff starts the cylinder 7 through the main control switch, so that the pressure plate 8 drives the heat sealing head 9 to move downward, thereby heat-sealing the bubble bag and cooperating with the cutter 10 to cut it. Finally, the bubble bag wraps the material and completes the packaging.

[0033] The bidirectional screw 13 is rotated by the operation of motor 18, and the distance between the two sets of sliders 14 is further shortened, so that the two sets of support plates 16 expand outward to fix the mounting roller 12. The gear 19 is controlled by the operation of motor 20 to rotate the rotating disk 11 to complete the rolling and unrolling of the bubble bag. Compared with the traditional device, the device can conveniently and quickly take and place the winding drum 30, making the disassembly and assembly of the winding drum 30 quick, further improving the packaging efficiency, saving time and effort.

[0034] Among them, the outer wall of the rotating disk 11 is provided with teeth, and a gear 19 is rotatably installed inside the packaging table 2. The gear 19 and the rotating disk 11 are engaged with each other. A motor 20 is fixedly installed inside the packaging table 2, and the output shaft of the motor 20 is fixedly connected to the gear 19.

[0035] When the material is being conveyed, the staff starts the motor 2 20 , and the operation of the motor 2 20 drives the gear 19 to rotate. The gear 19 and the rotating disk 11 engage with each other, so that the rotating disk 11 drives the installation roller 12 to rotate, thereby unwinding the bubble bag.

[0036] The threads at the front and rear ends of the bidirectional screw 13 are opened in opposite directions and have the same pitch. The two sets of sliders 14 are both slidably installed inside the guide groove 15.

[0037] Since the threads at the front and rear ends of the bidirectional screw 13 are opened in opposite directions, when the bidirectional screw 13 rotates, the two sets of sliders 14 move inwardly along the guide groove 15 synchronously.

[0038] Among them, a feed plate 21 is fixedly installed on the left side of the packaging table 2, and the feed plate 21 is used to connect with the materials on the conveyor 1.

[0039] The feed plate 21 is used to receive materials and to unfold the bubble bags.

[0040] Among them, a control groove 22 is opened inside the feed plate 21, and sliding plates 23 are slidably installed on the front and rear sides of the control groove 22. A gear 25 is rotatably installed in the middle of the control groove 22. Racks 24 are fixedly installed on the opposite sides of the two groups of sliding plates 23. The two groups of racks 24 are engaged with gear 25. Two groups of limiting grooves 26 are opened on the right side of the control groove 22. One end of the two groups of sliding plates 23 passes through the limiting groove 26 and is fixedly installed with a guide plate 27. A threaded rod 29 is rotatably installed on the front side of the feed plate 21. One end of the threaded rod 29 passes through the front sliding plate 23, and the threaded rod 29 and the front sliding plate 23 are threadedly connected.

[0041] When the feed plate 21 guides the material, the staff can adjust the spacing between the two sets of guide plates 27 according to the size of the material. The staff rotates the threaded rod 29, and the rotation of the threaded rod 29 drives the sliding plate 23 threadedly connected to it to move. However, the two sets of sliding plates 23 are provided with racks 24 on the opposite side, and the two sets of racks 24 are engaged with gear 2 25, so that the two sets of sliding plates 23 will move inward synchronously. Through this synchronous displacement, it can be ensured that the material is located in the middle of the two sets of guide plates 27. When the spacing between the two sets of guide plates 27 becomes smaller, the risk of material displacement during transportation can be reduced.

[0042] By rotating the threaded rod 29 to control the synchronous displacement of the two groups of guide plates 27, the interval between the two groups of guide plates 27 is further shortened, so that the device can accurately guide materials of different volumes, avoiding the deviation of materials during transportation. In addition, the friction between the guide plates 27 and the materials is reduced by setting multiple groups of rotating wheels 28, eliminating the problem of material jamming and improving packaging efficiency.

[0043] The left sides of the two groups of guide plates 27 are in an "eight" shape, which is used to guide the materials. Multiple groups of rotating wheels 28 are rotatably installed inside the two groups of guide plates 27.

[0044] The left side of the guide plate 27 is designed in an eight-shaped manner to guide the material step by step, and the setting of the rotating wheel 28 can prevent the material from getting stuck.

[0045] Among them, four groups of telescopic rods 31 are provided at the bottom of the heat sealing table 6 , and the other ends of the four groups of telescopic rods 31 are fixedly connected to the four corners of the pressing plate 8 .

[0046] The arrangement of the four sets of telescopic rods 31 ensures that the pressing plate 8 and the heat sealing head 9 can stably move vertically downward.

[0047] Among them, sliding grooves 32 are opened on the front and back sides of the left side wall of the pressure plate 8, and a movable plate 34 is slidably installed inside the two groups of sliding grooves 32. One end of the movable plate 34 and the sliding groove 32 are elastically connected by a spring 33, and a pressure roller 35 is rotatably installed at the bottom of the movable plate 34.

[0048] When the heat sealing head 9 is heat-sealing the bubble bag downward, the pressure roller 35 will first abut against the bubble bag. As the material moves, the pressure roller 35 will squeeze out the air inside the bubble bag. When the material moves to the appropriate position, the pressure plate 8 and the heat sealing head 9 move downward. Furthermore, the pressure roller 35 will fix the heat sealing position through the elastic potential energy of the spring 33, ensuring the stability of the sealing and cutting of the heat sealing head 9 and the cutter 10.

[0049] The guidance of the four sets of telescopic rods 31 makes the heat sealing head 9 and the cutter 10 more stable when sealing and cutting the bubble bag. The elastic design of the pressure roller 35 enables the pressure roller 35 to reduce the air inside the bubble bag by squeezing, thereby avoiding the problem of excessive air in the bag after heat sealing and damage during transportation. In addition, when the heat sealing head 9 is heat sealing, the pressure roller 35 can fix the heat sealing area by abutting, thereby improving the packaging effect.

[0050] Among them, a cutter 10 is fixedly installed at the bottom of the heat sealing table 6, and the position of the cutter 10 corresponds to the heat sealing head 9, and the pressure roller 35 is located at the lower left of the heat sealing head 9.

[0051] Working principle and usage process:

[0052] When it is necessary to use solvent-free composite aluminized film bubble bags to package materials, the staff first places the reel 30 for reeling in this type of bubble bag on the mounting roller 12, and then starts the motor 18. The operation of the motor 18 will drive the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 will drive the two sets of sliders 14 threadedly connected thereto to move. Furthermore, since the threads at the front and rear ends of the bidirectional screw 13 are opened in opposite directions, the two sets of sliders 14 are synchronously displaced inwardly along the guide groove 15. When the distance between the two sets of sliders 14 is shortened, since it is inconvenient to fix the length of the connecting rod 17, the connecting rod 17 will extend outward, and further the two sets of support plates 16 will move inwardly along the reel. The inner walls of 30 fit together to complete the fixation of the winding drum 30, and then the staff unfolds the bubble bag and lays it on the packaging table 2. At this time, the sealing part of the bubble bag will pass between the guide rollers of the two sets of guide mechanisms 4 in sequence, and when the bubble bag passes through the heated soldering iron 5, the top of the bubble bag will be heated and sealed. After the material is guided by the conveyor 1 and the feed plate 21 and transported to the conveyor belt 3, the material will enter the interior of the bubble bag and be further transported to the heat sealing table 6. At this time, the staff starts the cylinder 7 through the main control switch, so that the pressure plate 8 drives the heat sealing head 9 to move downward, thereby heat-sealing the bubble bag and cooperating with the cutter 10 to cut it. Finally, the bubble bag wraps the material and completes the packaging.
