Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This invention provides, for example Figure 1-14 The packaging mechanism for fastener packaging shown includes a mounting plate 1, a feeding cylinder 2 on the front side of the mounting plate 1, the feeding cylinder 2 being connected to the mounting plate 1 via a connecting rod 3, two heat-sealing plates 4 being provided between the feeding cylinder 2 and the mounting plate 1, the heat-sealing plates 4 being mounted on the mounting plate 1 via a first connecting frame 5, a first transverse heating block 6 and a second transverse heating block 7 being provided below the feeding cylinder 2, the first transverse heating block 6 and the second transverse heating block 7 being mounted on the mounting plate 1 via a second connecting frame 8, a drive frame 9 being mounted on the rear side of the mounting plate 1, the drive frame 9 being able to drive the heat-sealing plates 4, the first transverse heating block 6 and the second transverse heating block 7 to move synchronously, a feeding wheel 10 being provided below the heat-sealing plates 4, and a rotating frame 11 being mounted on the mounting plate 1.

[0020] The heat-sealing process of this device after packaging fasteners is as follows: Mounting plate 1 is installed on the front side of the fastener packaging machine. A roller wrapped with plastic film and a limiting device that pushes both ends of the plastic film inwards are installed on the upper part of the fastener packaging machine. The operator pulls the lower end of the plastic film downwards, causing it to wrap around the outside of the feeding cylinder 2. The two ends of the plastic film pass through the inside of the two heat-sealing plates 4 and fall between the two feeding rollers 10. The drive frame 9 drives the heat-sealing plates 4, the first transverse heating block 6, and the second transverse heating block 7 to move synchronously. This allows the two ends of the plastic film to be heat-sealed by the two heat-sealing plates 4, facilitating the formation of a cylindrical shape. Then, the two heat-sealing plates 4 are separated, and the rotating frame 11 drives the feeding rollers 10 to rotate, causing the plastic film to move downwards. When the lower end of the plastic film moves to the first transverse heating block 7... After the heating block 6 and the second transverse heating block 7 are positioned together, the heat sealing plate 4, the first transverse heating block 6, and the second transverse heating block 7 are moved synchronously and brought closer to each other by the drive frame 9. The two heat sealing plates 4 can then heat seal both ends of the plastic film, and the first transverse heating block 6 and the second transverse heating block 7 can heat seal the lower end of the plastic film. Then, the fasteners are added to the feed cylinder 2 by the fastener feeding device, followed by the plastic film. Then, the two heat sealing plates 4 are separated, and the first transverse heating block 6 and the second transverse heating block 7 are separated. Then, the feed wheel 10 is rotated by the rotating frame 11, which can continue to move the plastic film downward. Then, the heat sealing plate 4, the first transverse heating block 6, and the second transverse heating block 7 are moved synchronously by the drive frame 9, which facilitates the heat sealing of the plastic film and the separate placement of the fasteners.

One end of the first guide rod 14 passes through the first guide hole 13 and extends to the outside of the first movable block 12. A first stop block 15 is installed at the end of the first guide rod 14 located on the outside of the first movable block 12. A first telescopic spring 16 is fitted at the end of the first guide rod 14 located on the inside of the first movable block 12. A rotating plate 17 is installed at one end of the first movable block 12. Square openings 18 are opened on both sides of the upper end of the mounting plate 1. The rotating plate 17 extends from the square openings 18 to the rear side of the mounting plate 1. A fixing plate 19 is installed at the upper rear side of the mounting plate 1. The fixing plate 19 and the rotating plate 17 are rotatably connected by a pin structure 20. A fixing block 21 is installed at the upper rear side of the mounting plate 1. The rotating plate 17 is connected to the fixing block 21 by a return spring 22.

[0022] The process of installing the heat-sealing plate 4 by the first connecting frame 5 is as follows: the rotating plate 17 is connected to the fixed plate 19 through the pin structure 20, so that the first moving block 12 can be lifted. The first moving block 12 can lift the heat-sealing plate 4 through the first guide rod 14 and the first guide hole 13. The return spring 22 is located on the front side of the pin structure 20, so that the two heat-sealing plates 4 are in the open state under the elastic force of the return spring 22.

[0023] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Instruction manual attached Figure 7 Instruction manual attached Figure 8 Included with instruction manual Figure 11 A first connecting plate 23 is installed on one side surface of the first transverse heating block 6, and a knife groove 24 is opened on the inner side of the first transverse heating block 6.

A cutting knife 33 is provided on the inner side of the second transverse heating block 7. One end of the fixing rod 32 passes through the clearance opening 31 and connects to both ends of the cutting knife 33.

[0024] The process of the first transverse heating block 6 and the second transverse heating block 7 cutting the plastic film is as follows: Under normal conditions, the first transverse heating block 6 and the second transverse heating block 7 are in a separated state. When the drive frame 9 moves the first transverse heating block 6 and the second transverse heating block 7 closer, the second moving block 26 can be pushed. The second moving block 26 can push the second connecting plate 25 and the second transverse heating block 7 closer to the first transverse heating block 6 through the second telescopic spring 30. The second guide rod 28 and the second guide hole 27 can ensure the relative movement direction of the second transverse heating block 7 and the second moving block 26. When the first transverse heating block 6 contacts the second transverse heating block 7, the plastic film can be heat-sealed. Then the second moving block 26 continues to move, which can compress the second telescopic spring 30. Then the cutting blade 33 can be pushed into the blade groove 24 through the fixing rod 32, which can facilitate the cutting of the plastic film. Then the second moving block 26 returns to its original position. Under the elastic force of the second telescopic spring 30, the cutting blade 33 can be moved out of the blade groove 24.

[0026] The process of installing the first transverse heating block 6 and the second transverse heating block 7 by the second connecting frame 8 is as follows: The third guide rod 35 passes through the first guide cylinder 34 and the second guide cylinder 36 and connects to the second moving block 26, which can limit the position of the first connecting plate 23, the second connecting plate 25, and the second moving block 26, thereby connecting the first transverse heating block 6 and the second transverse heating block 7 to the mounting plate 1.

When the rotating shaft 47 drives the two second cams 50 to rotate, it can move one end of the rotating plate 17.

[0028] The process of the drive frame 9 driving the heat-sealing plate 4, the first transverse heating block 6, and the second transverse heating block 7 to move synchronously is as follows: The first servo motor 46 is started to rotate, which drives the rotating shaft 47 to rotate. The rotating shaft 47 drives the first cam 49 and the second cam 50 to rotate. When the rotating shaft 47 drives the second cam 50 to rotate, when the protruding end of the second cam 50 rotates to one side of the rotating plate 17, it can push the rotating plate 17 to one side. Then, under the action of the pin structure 20, the other end of the rotating plate 17 can be driven by the first moving block 12 to bring the two heat-sealing plates 4 closer together and compress the return spring 22. When the non-protruding end of the second cam 50 rotates to one side of the rotating plate 17, it separates under the elastic force of the return spring 22. When the rotating shaft 47 drives the protruding end of the first cam 49 to rotate to one side of the first pushing plate 38, it can push the first pushing plate 38 to one side. The outer side pushes and drives the third guide rod 35 to move. The third guide rod 35 can drive the second moving block 26 to move.

When the protruding end of the other first cam 49 rotates to the side of the second push plate 42, the second push plate 42 can be pushed to one side and the fourth telescopic spring 44 can be pushed. When the second push plate 42 moves, the first transverse heating block 6 can be pushed by the fourth guide rod 43, so that the first transverse heating block 6 and the second transverse heating block 7 can be brought close together and heat-sealed on the plastic film. When the non-protruding end of the first cam 49 rotates to the side of the first push plate 38 and the second push plate 42, the first transverse heating block 6 and the second transverse heating block 7 can be separated under the elastic force of the third telescopic spring 40 and the fourth telescopic spring 44.

[0031] The process of the rotating frame 11 driving the feed wheel 10 to rotate is as follows: the second servo motor 59 is started to rotate, the second servo motor 59 can drive the second gear 64 to rotate, the second gear 64 meshes with a first gear 63, and the two first gears 63 also mesh, which can make the two first gears 63 rotate in opposite directions, and drive the two feed wheels 10 to rotate through the rotating rod 61, which can make the two feed wheels 10 rotate in opposite directions, and pull the plastic film downward.

[0032] Refer to the instruction manual appendix Figure 1 The outer side of the feed roller 10 is provided with friction grooves, which can increase the friction between the feed roller 10 and the plastic film, making it easier to move the plastic film downward.

[0033] Refer to the instruction manual appendix Figure 7 Instruction manual attached Figure 10 Instruction manual attached Figure 11 Included with instruction manual Figure 12The second fixed frame 58 includes a mounting frame 65 and a movable frame 66. The mounting frame 65 is fixedly mounted on the mounting plate 1. The fifth rolling bearing 62 on the rotating rod 61 near the second servo motor 59 is mounted on the mounting frame 65. The movable frame 66 has L-shaped limiting blocks 67 mounted on the mounting plate 1 above and below. The two ends of the movable frame 66 extend into the inside of the L-shaped limiting blocks 67. The fifth rolling bearing 62 on the rotating rod 61 away from the second servo motor 59 is mounted on the movable frame 66. The clearance hole 60 on the side away from the second servo motor 59 is elongated. The first gear 63 on the two rotating rods 61 can mesh and disengage. The movable frame 66 has a limiting frame 68 mounted on the mounting plate 1 on one side, which can limit the movable frame 66.

[0034] The process of separation and contact of the two feed rollers 10 is as follows: When it is necessary to feed plastic film, the moving frame 66 is pushed to one side by the limiting frame 68. At this time, the rotating rod 61 on the moving frame 66 is positioned close to the rotating rod 61 on the mounting frame 65. At this time, the two first gears 63 are in a meshing state, and the two feed rollers 10 are also in a contact position. When it is necessary for the operator to pull the plastic film downward, the limiting frame 68 is released. At this time, the rotating rod 61 on the moving frame 66 can move to the other side of the clearance hole 60. The L-shaped limiting block 67 can ensure the moving direction of the moving frame 66. At this time, the first gears 63 on the two rotating rods 61 are separated, and there is also a gap between the two feed rollers 10, which makes it convenient for the operator to pull the plastic film downward.

[0035] Refer to the instruction manual appendix Figure 11 Instruction manual attached Figure 12 Included with instruction manual Figure 14 The limiting frame 68 includes a connecting block 69 located on one side of the movable frame 66. The connecting block 69 is mounted on the mounting plate 1. A sixth rolling bearing 70 is mounted on the connecting block 69. A drive shaft 71 is installed inside the sixth rolling bearing 70. A circular hole 72 is opened on the mounting plate 1. One end of the drive shaft 71 passes through the circular hole 72 and extends to the front side of the mounting plate 1. A third cam 73 is mounted on the drive shaft 71. An arc-shaped groove 74 is opened on one side of the movable frame 66.

[0036] The process of limiting the movable frame 66 by the limiting frame 68 is as follows: The operator rotates the drive shaft 71. When the protruding end of the third cam 73 on the drive shaft 71 rotates to the side of the arc groove 74, the movable frame 66 can be moved closer to the mounting frame 65. When the non-protruding end of the third gear 73 on the drive shaft 71 rotates to the side of the arc groove 74, the movable frame 66 can be released.
