Description

Technical Field

[0001] This invention relates to the field of heat sealing machines, and is specifically titled "Heat Sealing Machine for Heat Shrink Wrapping Film of Batteries". Background Technology

[0002] Heat shrink tubing is a specially designed heat shrink sleeve made of polyolefin material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive.

[0025] Please see Figure 1-8This invention provides a technical solution: a heat-sealing machine for heat-shrinkable outer wrapping of batteries, comprising a base 1, a support column 2 fixedly installed above the base 1, a base plate 3 provided on the rear side of the support column 2, a first cylinder 4 fixedly installed above the base plate 3, a first air rod 5 slidably connected to the inner side of the first cylinder 4, a rack plate 6 fixedly installed on the front side of the first air rod 5, a bearing block 7 fixedly installed above the base plate 3, an adapter rod 9 provided on the inner side of the bearing block 7, and an adapter gear 8 fixedly installed on the right side of the adapter rod 9, the adapter gear 8 and the rack plate... 6. The components are interconnected. An adjusting gear 10 is fixedly installed on the left side of the adapter rod 9. An mounting plate 11 is fixedly installed on the top of the base plate 3. A left toothed plate 12 is slidably connected to the left side of the mounting plate 11, and a right toothed plate 13 is slidably connected to the left side of the mounting plate 11. The adjusting gear 10 is between and meshes with the left toothed plate 12 and the right toothed plate 13. A first growth rod 14 is fixedly installed on the top of the left toothed plate 12, a second growth rod 15 is fixedly installed on the top of the right toothed plate 13, and a third growth rod 16 is fixedly installed on the top of the support column 2. An upper horizontal plate 17 is fixedly installed above the first growth rod 14, and a lower horizontal plate 18 is fixedly installed above the second growth rod 15. Both the upper horizontal plate 17 and the lower horizontal plate 18 are slidably connected to the third growth rod 16. After the first cylinder 4 is started, it drives the first internal air rod 5 to push outward, thereby driving the rack plate 6 forward. At this time, the adapter gear 8 meshing with it will be driven to rotate counterclockwise. The adapter gear 8 drives the adjusting gear 10 to rotate counterclockwise in the same way through the adapter rod 9. At this time, the left gear plate 12 meshing with the adjusting gear 10 will... The right toothed plate 13, which meshes with the adjusting gear 10, will slide downwards, and the left toothed plate 12 will drive the upper horizontal plate 17 to slide downwards on the third horizontal plate 16 through the first extension rod 14. Similarly, the right toothed plate 13 will drive the lower horizontal plate 18 to slide upwards on the third horizontal plate 16 through the second extension rod 15. This achieves the closing effect of the upper horizontal plate 17 and the lower horizontal plate 18 by controlling the single first cylinder 4. The closing efficiency is high, the manufacturing cost is reduced, and the closing speed can be changed by replacing the first cylinder 4 in the later stage. It is highly practical.

[0026] A sealing machine 19 is slidably connected to the lower part of the upper horizontal plate 17. A first buffer rod 23 is provided above the upper sealing machine 19, and a first buffer block 22 is provided above the first buffer rod 23. The first buffer rod 23 is slidably connected to the upper horizontal plate 17, and the first buffer block 22 is connected to the upper horizontal plate 17. A sealing machine 20 is slidably connected to the upper part of the lower horizontal plate 18, and a second buffer block 24 is provided below the lower sealing machine 20. The second buffer block 24 is fixedly connected to the lower horizontal plate 18. A first heat dissipation hole 21 is provided on the outer side of the upper sealing machine 19. When the battery 54 is below the upper sealing machine 19 and is covered with a heat sealing film, heat sealing begins. The upper sealing machine 19 is moved downward by the upper horizontal plate 17. The lower sealing machine 20 is moved upward by the lower horizontal plate 18. After the upper sealing machine 19 comes into contact with the lower sealing machine 20, the first buffer block 22 and the second buffer block 24 cooperate to counteract the thrust of the upper horizontal plate 17 and the lower horizontal plate 18. This prevents the first cylinder 4 from failing to stop in time after the upper sealing machine 19 comes into contact with the lower sealing machine 20, which could damage components such as the adapter gear 8. Subsequently, the upper sealing machine 19 and the lower sealing machine 20 start heating to perform heat sealing operation on the battery 54 and heat sealing film clamped inside. Excess heat will be discharged from the first heat dissipation hole 21 to prevent the temperature from getting too high. After the heat sealing is completed, timely heat dissipation treatment is performed inside to achieve a wrap-around heat sealing effect. The heat sealing efficiency is high, and the heat sealing shape will not deviate, making it practical.

[0027] A heightening column 25 is fixedly installed above the base 1. A second cylinder 26 is fixedly installed on the rear side of the heightening column 25. A second air rod 27 is slidably connected inside the second cylinder 26. A conveying ring 28 is fixedly installed on the inner side of the second air rod 27. A power wheel 29 is provided inside the conveying ring 28. A rotary cutting table 30 is fixedly installed on the front side of the conveying ring 28. A telescopic cutting blade 31 is provided inside the rotary cutting table 30. When the battery 54 is below the upper sealing machine 19, the second cylinder 26 drives the internal second air rod 27 to move forward. Then, the power wheel 29 inside the conveying ring 28 starts to rotate. The heat sealing film is inserted into the conveying ring 28, and a conveying rod is provided inside the heat sealing film for support. This conveying rod is inside the conveying ring 28 and fits against the power wheel 29. The power wheel 29 is provided with a spring inside the conveying ring 28, which can press and displace slightly inward within the conveying ring 28, thereby causing the outer side of the conveying rod to be heat sealed. When the film is being cut, the power wheel 29 can move inward to allow the heat-sealing film to be smoothly fitted onto the top of the conveyor rod. An internal spring causes the power wheel 29 to rotate, propelling the heat-sealing film forward. After the second air rod 27 brings the entire assembly into contact with one end of the battery 54, the power wheel 29 rotates. Since the internal conveyor rod is in contact with the battery 54 and cannot be propelled by the power wheel 29, the heat-sealing film is propelled forward by the power wheel 29, transferring from the conveyor rod to the battery 54. When the top of the heat-sealing film exceeds the battery 54, the power wheel 29 stops rotating. Subsequently, the rotating cutting table 30 rotates, driving the telescopic cutting blade 31 extending from the rotating cutting table 30 to quickly cut the heat-sealing film. The heat-sealing film is internally supported by the conveyor rod and is not subjected to excessive deformation during cutting. Then, the second cylinder 26 retracts via the second air rod 27 to return the entire assembly to its original position, thus achieving automatic fitting and cutting of the heat-sealing film, making it highly practical.

[0028] A support frame 32 is fixedly installed on the top of the base 1. A drive sprocket 33 is fixedly installed on the top of the support frame 32. A chain 34 is engaged on the outer side of the drive sprocket 33. A driven sprocket 51 is connected to the bearing on the inner side of the support frame 32. The chain 34 and the driven sprocket 51 are engaged with each other. A fork plate 35 is fixedly installed inside the chain 34. A battery 54 is placed on the top of the fork plate 35. When the drive sprocket 33 rotates, the driven sprocket 51 is driven to rotate through the chain 34. At the same time, the battery 54 will be placed on the fork plate 35 before and after heat sealing to achieve the effect of transportation.

[0029] A collection chamber 38 is fixedly installed on the top of the support frame 32. A push plate 39 is spring-connected to one side of the collection chamber 38. A rotating rod 36 is connected to the top of the support frame 32 by a bearing. A chuck 37 is provided on the outer side of the rotating rod 36. A power chain 52 is engaged on one side of the rotating rod 36. The power chain 52 is engaged with the outer side of the driven sprocket 51. When the driven sprocket 51 rotates, it will drive the rotating rod 36 to rotate together through the power chain 52. When the rotating rod 36 rotates, the chuck 37 on the rotating rod 36 will rotate accordingly. A battery 54 will be locked between the two chucks of the chuck 37. When the battery 54 is placed in the collection chamber 38 and pushed to the left by the push plate 39 to make it level with each other, it will be locked by the rotating chuck 37 and driven to the lower side of the collection chamber 38 and then fall onto the fork plate 35. This achieves the transportation of the battery 54 after heat sealing and the placement of the battery 54 before heat sealing through a power sprocket 33, thereby reducing errors in the subsequent heat sealing operation.

[0030] A third cylinder 40 is fixedly installed above the base 1. A third air rod 41 is slidably connected inside the third cylinder 40. A processing plate 53 is fixedly installed above the third air rod 41. A motor 42 is fixedly installed above the processing plate 53. A first gear 43 is fixedly installed at the power end of the motor 42. A second gear 44 and a third gear 45 are connected to the lower bearing of the processing plate 53. The first gear 43 and the second gear 44 are meshed with each other. The second gear 44 and the third gear 45 are meshed with each other. A first moving wheel 46 is arranged above the second gear 44. A second moving wheel 47 is arranged above the third gear 45. A push column 49 is arranged inside the first moving wheel 46 and the second moving wheel 47. A limit turntable assembly 48 is arranged above the processing plate 53. The push column 49 is arranged between the limit turntable assemblies 48. A suction head 50 is located on the front side of the push column 49. 2. The rotation of the first gear 43 drives the second gear 44 and the third gear 45 to rotate, causing the first moving wheel 46 and the second moving wheel 47 above to rotate together with the second gear 44 and the third gear 45. This causes the push column 49 held on the inner side to extend forward. Then, the air pump inside the push column 49 starts and sucks up the battery 54 on the fork plate 35 through the suction head 50. Then, the third cylinder 40 starts and drives the third air rod 41 to extend upward, thereby lifting the processing plate 53. When the battery 54 reaches the designated position, the third cylinder 40 stops, and the motor 42 continues to rotate, driving the battery 54 into the upper sealing machine 19 and the lower sealing machine 20. Then, the battery 54 is heat-sealed. After the heat sealing is completed, the third cylinder 40 and the motor 42 work together to put the battery 54 back on the fork plate 35, and then wait for the next battery 54. This achieves the effect of changing the position of the battery 54 and sending it to the heat sealing machine, which is practical.
