Description

Technical Field

[0001] This utility model relates to the field of heat sealing technology, and in particular to a high-strength heat sealing component for an automatic packaging machine based on PLC. Background Technology

[0002] Heat sealing is a process that achieves sealing by heating materials to a viscous state and then applying pressure to bond them together. It is widely used in packaging, waterproof products and other fields. When PLCs are used for automatic packaging, the opening needs to be heat-sealed.

[0003] The existing high-strength heat-sealing components of PLC automatic packaging machines require placing the open PLC on the support table surface first, and then pressing the opening of the PLC with a downward heating plate to heat-seal the opening.

[0004] However, batch heat sealing can cause wrinkles at the PLC opening, resulting in poor sealing and air leakage, thus reducing PLC packaging efficiency. Therefore, this invention proposes a high-strength heat sealing component for an automatic packaging machine based on a PLC. Utility Model Content

[0005] The purpose of this invention is to address the problem in the background technology that wrinkles occur at the opening position of the PLC during batch heat sealing, which leads to poor sealing at the opening position of the PLC during heat sealing, resulting in air leakage and low PLC packaging efficiency. The invention proposes a high-strength heat sealing component for an automatic packaging machine based on PLC.

[0006] The technical solution of this utility model: a high-strength heat sealing component for an automatic packaging machine based on PLC, including a sealing platform, a pressing block above the sealing platform, a base platform fixedly connected to the bottom of the sealing platform, a bonding wheel abutting the top of the sealing platform, a rack on one side of the bonding wheel, a gear meshing on one side of the rack, a threaded rod fixedly connected inside the gear, and the threaded rod rotatably connected inside the pressing block;

[0007] The threaded rod is rotatably connected to the top of the base plate at the end away from the lower pressure block. A sliding rod is slidably connected inside the lower pressure block at a position away from the base plate. The end of the sliding rod away from the lower pressure block is fixedly connected to the top of the base plate.

[0008] The bonding wheel is rotatably connected to a support frame, and a positioning frame is provided on the outside of the support frame. The positioning frame is fixedly connected to one side of the rack, and a connecting mechanism is provided between the positioning frame and the support frame.

[0009] Optionally, a slide rail is slidably connected to the bottom of the rack, and a positioning platform is fixedly connected to the bottom of the slide rail, with the positioning platform fixedly connected to the top of the encapsulation platform.

[0010] Optionally, the connecting mechanism includes a spring, which is fixedly connected to the top of the support frame, and the end of the spring away from the support frame is fixedly connected to the bottom of the positioning frame.

[0011] Optionally, the support frame is C-shaped, the positioning frame is L-shaped, and the spring has a telescopic mechanism inside.

[0012] Optionally, the telescopic mechanism includes a telescopic rod, which is fixedly connected to the support frame and the positioning frame on opposite sides, and the telescopic rod is disposed inside the spring.

[0013] Optionally, a limiting slide rod is fixedly connected to the support frame near the spring, and the limiting slide rod is slidably connected inside the spring.

[0014] Optionally, there are two limiting slide rods arranged symmetrically, and the limiting slide rods are arranged in a "T" shape.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] This invention employs a pressing block that presses down onto the encapsulation platform for heat sealing.

This gear, in turn, drives the bonding wheel to roll and flatten the PLC opening position placed on the encapsulation platform. This allows the pressing block to be pressed against the encapsulation platform for heat sealing, increasing the flattening effect of the PLC opening position and improving the PLC's encapsulation effect.

[0029] Example

[0030] like Figure 1 and Figure 3As shown, the high-strength heat-sealing component of the automatic packaging machine based on PLC proposed in this utility model includes a sealing platform 1, a pressing block 2 above the sealing platform 1, the pressing block 2 pressing down to the sealing platform 1 to seal the PLC, a base platform 3 fixedly connected to the bottom of the sealing platform 1, and a bonding wheel 4 abutting the top of the sealing platform 1. The bonding wheel 4 can flatten the sealing position of the PLC. A rack 7 is provided on one side of the bonding wheel 4, and a gear 6 meshes on one side of the rack 7. The rotation of the gear 6 can drive the rack 7 to move. A threaded rod 5 is fixedly connected inside the gear 6. The threaded rod 5 is rotatably connected inside the pressing block 2. The pressing block 2 pressing down will drive the threaded rod 5 to rotate, thus the threaded rod 5 will drive the gear 6 to rotate. The threaded rod 5 is rotatably connected to the top of the base platform 3 at the end away from the lower pressure block 2. The threaded rod 5 rotates more stably at the top of the base platform 3. A sliding rod 9 is slidably connected inside the lower pressure block 2 at the position away from the base platform 3. The sliding rod 9 can restrict the lower pressure block 2. The end of the sliding rod 9 away from the lower pressure block 2 is fixedly connected to the top of the base platform 3. A support frame 12 is rotatably connected to the outside of the contact wheel 4. The contact wheel 4 can rotate with the support frame 12. A positioning frame 10 is provided outside the support frame 12. The positioning frame 10 is fixedly connected to one side of the rack 7. The rack 7 can drive the positioning frame 10 to move, thereby allowing the positioning frame 10 to drive the support frame 12 to move. A connecting mechanism is provided between the positioning frame 10 and the support frame 12.

[0031] For further details, please refer to Figures 2 to 4 The rack 7 is slidably connected to a slide rail 15 at its bottom, which supports the rack 7 to slide on its top. A positioning platform 16 is fixedly connected to the bottom of the slide rail 15 and is fixedly connected to the top of the encapsulation platform 1. The positioning platform 16 can support the slide rail 15. An extension opening 8 is provided near the bottom platform 3 of the positioning platform 16. The end of the PLC can pass through the extension opening 8. The extension opening 8 is the same length as the encapsulation platform 1 and can pass through the encapsulation platform 1. The connecting mechanism includes a spring 11, which is fixedly connected to the top of the support frame 12 and can extend and retract at the support frame 12. The end of the spring 11 away from the support frame 12 is fixedly connected to the bottom of the positioning frame 10 and can extend and retract at the positioning frame 10 and the support frame 12.

[0032] For further details, please refer to Figure 3 and Figure 4The support frame 12 is C-shaped, which facilitates the rotation of the contact wheel 4. The positioning frame 10 is L-shaped, and its structure does not affect the movement of the support frame 12 and the contact wheel 4. The spring 11 has a telescopic mechanism inside, which includes a telescopic rod 13. The telescopic rod 13 is fixedly connected to the opposite side of the support frame 12 and the positioning frame 10. The telescopic rod 13 can block the spring 11 from extending or retracting. The telescopic rod 13 is located inside the spring 11. The support frame 12 is fixedly connected to a limiting slide rod 14 near the spring 11. The limiting slide rod 14 can restrict the support frame 12. The limiting slide rod 14 is slidably connected inside the spring 11. There are two limiting slide rods 14 arranged symmetrically. The symmetrical structure of the limiting slide rod 14 can prevent the support frame 12 from rotating. The limiting slide rod 14 is T-shaped, and its structure can prevent it from detaching from the positioning frame 10.

[0033] In this embodiment, during encapsulation, the PLC is placed on the encapsulation platform 1, with one end of the PLC protruding from the outlet 8. At this time, the pressure block 2 can be pressed down to perform heat sealing. When the pressure block 2 is pressed down, it will drive the threaded rod 5 to rotate at one end of the base platform 3. In this way, the threaded rod 5 will drive the gear 6 to rotate, thereby causing the rack 7 to move. When the rack 7 moves, it can drive the bonding wheel 4 to slide along the top of the encapsulation platform 1. In this way, the encapsulation platform 1 can roll and flatten the part of the PLC that needs to be heat sealed.

[0034] The bonding wheel 4 is supported by the support frame 12, allowing it to rotate on the top of the packaging platform 1. The support frame 12 slides inside the positioning frame 10 via the limiting slide rod 14, allowing the bonding wheel 4 to adapt to PLCs of different thicknesses. The positioning frame 10 is connected to the rack 7, so it can move with the movement of the rack 7. The spring 11 and the telescopic rod 13 can push the support frame 12, causing the support frame 12 to drive the bonding wheel 4 to slide on the top of the packaging platform 1. In this way, the bonding wheel 4 ensures the compression and bonding effect with the PLC.

[0035] When the rack 7 moves, the movement position of the rack 7 is restricted by the slide rail 15, and the slide rail 15 is supported by the positioning table 16 to ensure that the threaded rod 5 does not move, and to ensure that the rack 7 slides more stably on the top of the slide rail 15. When the lower pressure block 2 is pressed down, in order to avoid the lower pressure block 2 from breaking at the connection position due to excessive stress, the movement of the lower pressure block 2 can be restricted by the sliding rod 9.

[0036] It should be noted that this device uses a pressing block 2 to press down onto the encapsulation platform 1 for heat sealing. The pressing block 2 will drive the threaded rod 5 to rotate, which in turn drives the gear 6 to rotate. In this way, the gear 6 can drive the bonding wheel 4 to roll and flatten the PLC opening position placed on the encapsulation platform 1, thereby pressing the pressing block 2 against the encapsulation platform 1 for heat sealing. This increases the flattening effect of the PLC opening position and improves the encapsulation effect of the PLC.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
