[0001] This invention relates to the field of packaging machine technology, and in particular to a packaging device for a packaging machine. Background Technology

[0002] After small electronic components are manufactured, they are typically arranged on a conveyor belt for easy storage, transportation, and retrieval. This conveyor belt is then rolled into a roll. Before use, the roll is cut into sheets as needed, stacked, and then sealed in packaging film and placed in a container for supply. Currently, many factories still use manual cutting and packaging of the conveyor belt, a method that is inefficient and labor-intensive. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a packaging device for a packaging machine, which, combined with the conveying device configured in the packaging machine, enables fully automated production.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The hot cutter is mounted on the side wall of the clearance groove. The pre-compression component is located in the clearance groove. The two ends of the first elastic component are respectively connected to the pre-compression component and the cutter mounting plate.

[0009] When the hot cutting blade assembly approaches the heat sealing platform, the pre-compression member contacts the heat sealing platform before the hot cutting blade.

[0010] Preferably, the packaging apparatus further includes a coating plate; the coating plate can be close to or away from the heat sealing platform;

[0011] One side of the heating plate is provided with a second opening that communicates with the clearance groove. The hot cutting blade is arranged in a U-shape around the side wall of the clearance groove. The rubber-coated pressure plate extends into the clearance groove through the second opening.

[0012] Preferably, the pre-compression component includes a sliding rod that passes through the cutter mounting plate and can slide up and down relative to the cutter mounting plate, and a membrane pressure plate connected to the sliding rod. The membrane pressure plate is U-shaped. The first elastic member is fitted onto the sliding rod, and the two ends of the first elastic member abut against the membrane pressure plate and the cutter mounting plate, respectively.

[0027] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0028] like Figures 1 to 7 As shown, a packaging device for a packaging machine includes a packaging film guiding mechanism 1, a hot cutting blade assembly 2, and a heat sealing platform 3; the packaging film guiding mechanism 1 includes a fixing frame 11 and a plurality of guide rods 12 mounted on the fixing frame 11; the heat sealing platform 3 is opposite to the hot cutting blade assembly 2 and spaced apart, and the hot cutting blade assembly 2 can move closer to and further away from the heat sealing platform 3;

[0029] The guide rod 12 is used to guide the movement of the packaging film. The packaging film moves along the guide rod 12 to form a packaging film moving belt. The hot cutting knife assembly 2 and the heat sealing platform 3 are located on one side of the packaging film moving belt.

[0030] In this embodiment, the packaging device for the packaging machine, during operation, has guide rods 12 arranged and installed on the fixed frame 11. The packaging film moves along the guide rods 12 to form a packaging film moving belt. One side of the packaging film moving belt is the hot cutting blade assembly 2 and the heat sealing platform 3, and the other side is a conveying device configured in the packaging machine. The conveying device pushes the product to be packaged onto the heat sealing platform 3. When pushing the product, a portion of the packaging film moving belt is also pushed onto the heat sealing platform 3. At this time, the pushed portion of the packaging film moving belt wraps around the product to be packaged. Then, the hot cutting blade assembly 2 approaches the heat sealing platform 3 and cuts off the portion of the packaging film wrapped around the product. At this time, the packaging film moving belt returns to its original position, and a rectangular-like groove is cut out in the middle of the packaging film moving belt. Through the push-in design, the product to be packaged is wrapped by the packaging film during movement, achieving automated wrapping. Combined with the cutting action of the hot cutting blade assembly 2, automated packaging is achieved.

[0031] In this embodiment, the hot cutting blade assembly 2 includes a cutting blade mounting plate 21, a heating plate 22, a hot cutting blade 23, a pre-compression member 24, and a first elastic member 25;

[0032] The heating plate 22 and the pre-compression member 24 are both mounted on the cutter mounting plate 21. The heating plate 22 is provided with a relief groove 26. The hot cutter 23 is mounted on the side wall of the relief groove 26. The pre-compression member 24 is located in the relief groove 26. The two ends of the first elastic member 25 are respectively connected to the pre-compression member 24 and the cutter mounting plate 21.

[0033] When the hot cutting blade assembly 2 approaches the heat sealing platform 3, the pre-compression member 24 contacts the heat sealing platform 3 before the hot cutting blade 23.

[0034] During the hot cutting process, the packaging machine's conveying device moves the product to be packaged to the upper side of the heat sealing platform 3 and then exits. The hot cutting blade assembly 2 is driven by a cylinder to move down and engage with the heat sealing platform 3. During engagement, the pre-compression member 24 abuts against the packaging film located on the side of the product to be packaged before the hot cutting blade 23. When the pre-compression member 24 moves, the first elastic member 25 is compressed, so that the pre-compression member 24 has downward pressure and vertical floating space. After the pre-compression member 24 is in place, the hot cutting blade 23 begins to move down relative to the pre-compression member 24 and finally cuts the packaging film located on the side of the product to be packaged, completing the hot cutting action.

[0035] In this embodiment, the packaging device further includes a coating plate 13; the coating plate 13 can be close to or away from the heat sealing platform 3;

[0036] The heating plate 22 has a second opening 27 on one side that communicates with the clearance groove 26. The hot cutting blade 23 is arranged in a U-shape around the side wall of the clearance groove 26. The rubber-coated pressure plate 13 extends into the clearance groove 26 through the second opening 27.

[0037] After the packaging machine's conveying device transfers the product to be packaged to the upper side of the heat-sealing platform 3, the cylinder drives the overlay pressure plate 13 to move down and press the product to be packaged, ensuring that the product remains stationary during the heat-cutting process. The U-shaped design of the second opening 27 and the heat-cutting blade 23 is because the front side of the product to be packaged does not need to be heat-cut. When the product pushes against the packaging film, the front side of the product directly abuts against the complete surface of the packaging film, meaning that the packaging film on the front side of the product is a complete surface. Therefore, only the left and right sides and the rear side of the product need to be heat-cut. At the same time, the design of the second opening 27 facilitates the insertion of the overlay pressure plate 13.

[0038] In this embodiment, the pre-compression member 24 includes a sliding rod 28 that passes through the cutter mounting plate 21 and can slide up and down relative to the cutter mounting plate 21, and a membrane pressure plate 29 connected to the sliding rod 28. The membrane pressure plate 29 is U-shaped. The first elastic member 25 is fitted onto the sliding rod 28, and the two ends of the first elastic member 25 abut against the membrane pressure plate 29 and the cutter mounting plate 21, respectively.

[0039] The membrane pressing plate 29 is configured in a U-shape to cooperate with the clearance groove 26 and the hot cutting blade 23. During hot cutting, the membrane pressing plate 29 abuts against the left and right sides and the rear side of the packaged product before the hot cutting blade 23, so that the pre-pressing position corresponds to the cutting position of the hot cutting blade 23.

[0040] In this embodiment, the packaging film guiding mechanism 1 further includes a packaging film support 14, a film delivery roll 15 and a film take-up roll 16 mounted on the packaging film support 14 and capable of rotation.

[0041] The packaging film support 14 is located on one side of the packaging film guide mechanism 1, and the film output roll 15 is located above the film take-up roll 16. The film output roll 15 is used to mount the packaging film roll, and the film take-up roll 16 is used to take up the packaging film whose middle part has been cut off. That is to say, the packaging film roll of the film output roll 15 is released by rotating, and the packaging film moves along the guide rod 12 and is finally recycled to the film take-up roll 16 to form a waste film roll.

[0042] In this embodiment, the packaging film guiding mechanism 1 further includes two tensioning components. Both tensioning components are installed on the fixed frame 11 and are respectively configured to cooperate with the film output roll 15 and the film take-up roll 16. The tensioning components include two swing rods 31 and a guide rod 32 with both ends connected to the two swing rods 31 respectively. The swing rods 31 are rotatably connected to the fixed frame 11.

[0043] Of the two tensioning components, one is installed at the upper end of the fixing frame 11, corresponding to the film delivery roll 15, and the other is installed at the lower end of the fixing frame 11, corresponding to the film take-up roll 16. During movement, the packaging film passes under the guide rod 32, while the swing rod 31 can swing freely. When the packaging film is pulled forward, the guide rod 32 swings upward to allow the packaging film to be pulled forward with sufficient length. When the packaging film loses tension, the guide rod 32 swings downward due to gravity, restoring the packaging film to its original tension and allowing it to continue moving forward.

[0044] In this embodiment, the packaging film guiding mechanism 1 further includes a limiting block 17; the limiting block 17 is located on one side of the tensioning assembly that is configured to cooperate with the film take-up roll 16, and the limiting block 17 can extend to prevent the swing rod 31 from moving.

[0045] The limiting block 17 is used to restrict the tensioning assembly installed at the lower end of the fixing frame 11. By extending the limiting block 17, the swing rod 31 is restricted, ensuring that the swing rod 31 remains fixed when the film take-up roll 16 rotates to collect waste film. This prevents the formation of tension when collecting waste film, which would cause the guide rod 32 to swing upward prematurely and affect the next normal tension adjustment.

[0046] In this embodiment, a linear module 4 is also included, which connects to the heat-sealing platform 3. The linear module 4 drives the heat-sealing platform 3 to move closer to and away from the hot-cutting blade assembly 2. The linear module 4 allows the heat-sealing platform 3 to reciprocate between the feeding device configured on the packaging machine and the hot-cutting blade assembly 2. When it moves below the hot-cutting blade assembly 2, it engages with the hot-cutting blade assembly 2 to complete the hot-cutting action. When it moves closer to the feeding device configured on the packaging machine, the feeding device removes the packaged product.
