Description

Technical Field

[0001] This utility model relates to the field of heat sealing technology, and in particular to a heat sealing control device for automatic packaging machines. Background Technology

[0002] Automatic packaging machines, as indispensable equipment in modern industrial production, are automated packaging devices integrating mechanical, electronic, pneumatic, and photoelectric detection technologies. They can automatically complete a series of packaging processes such as material metering, filling, sealing, printing, and labeling according to preset programs, greatly improving packaging efficiency and quality stability. Depending on the packaging process, automatic packaging machines can be divided into various types, such as filling packaging machines, sealing packaging machines, wrapping packaging machines, and strapping packaging machines, and are widely used in many industries such as food, pharmaceuticals, chemicals, and daily necessities. Existing automatic packaging machines typically use cylinders or electric push rods to directly apply heat-sealing pressure to the heat-sealing block. While this direct pressure application method can achieve basic heat-sealing, the output pressure of the cylinders or electric push rods is difficult to control precisely and flexibly. When encountering packaging bags of different materials and thicknesses, excessive pressure can easily occur, causing the packaging bag to break during the heat-sealing process. This not only wastes packaging materials but also reduces packaging efficiency, increases production costs, and affects the product's sealing performance and packaging quality. Therefore, this utility model proposes a heat-sealing control device for automatic packaging machines. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where cylinders or electric push rods are used to directly apply heat-sealing pressure to the hot press block. While this direct pressure application method can achieve basic heat-sealing, it is difficult to achieve precise and flexible control of the output pressure of the cylinders or electric push rods during operation. When encountering packaging bags of different materials and thicknesses, excessive pressure can easily occur, causing the packaging bags to break during the heat-sealing process. This not only wastes packaging materials but also reduces packaging efficiency, increases production costs, and affects the sealing and packaging quality of the product. Therefore, this invention proposes a heat-sealing control device for automatic packaging machines.

[0004] The technical solution of this utility model: A heat-sealing control device for an automatic packaging machine includes: a base, on the upper surface of which two conveying components for conveying packaging bags are fixedly installed; a frame fixedly installed on the upper surface of the base, and the frame is located between the conveying components; an electric push rod is fixedly installed on the upper surface of the frame, the output end of the electric push rod passes through the frame and extends to connect to a fixed plate; a heat-pressing component for heat sealing is provided on the fixed plate; a lower heat-pressing plate is provided between the conveying components, the lower heat-pressing plate is fixedly connected to the frame, and the lower heat-pressing plate is located directly below the fixed plate.

[0005] Optionally, the hot pressing assembly includes a connecting plate, an upper hot pressing plate is fixedly disposed on the bottom surface of the connecting plate, and a set of first connecting seats are fixedly disposed on both sides of the connecting plate, a linkage rod is rotatably connected to the first connecting seat, and a second connecting seat is rotatably connected to one end of the linkage rod.

[0006] Optionally, the hot pressing assembly further includes a set of fixed frames fixedly disposed on both sides of the electric push rod, a threaded rod rotatably disposed between the fixed frames, a threaded sleeve block threadedly sleeved on the outer wall of the threaded rod, a sleeve block movably sleeved on the outer wall of the threaded rod, the sleeve block being fixedly connected to the fixed frame, a spring sleeved on the outer wall of the threaded rod, one end of the spring being fixedly connected to the threaded sleeve block, and the other end of the spring being fixedly connected to the sleeve block.

[0007] Optionally, the frame has grooves on both sides, and a slider is slidably disposed inside the groove, the slider being fixedly connected to the fixing plate.

[0008] Optionally, the bottom surface of the fixing plate is provided with a guide groove, and a guide block is slidably disposed inside the guide groove, the guide block being fixedly connected to the connecting plate.

[0009] Optionally, the threaded socket block and the socket block are configured with an "H" shaped structure.

[0010] Optionally, one end of the threaded rod passes through the fixed frame and extends to be connected to a rotating cap.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention utilizes the structure of a threaded rod, a threaded sleeve block, a sleeve block, and a spring in a hot-pressing assembly. When the electric push rod drives the hot-pressing assembly to press down, the threaded rod can be adjusted by rotating the rotating cap to change the position of the threaded sleeve block, thereby adjusting the compression degree of the spring. This effectively controls the heat-sealing pressure, allowing the hot-pressing assembly to apply appropriate pressure according to actual needs when contacting packaging bags of different materials and thicknesses. This prevents the packaging bags from being crushed due to excessive pressure, effectively reducing waste of packaging materials, improving packaging efficiency, and lowering production costs.

[0013] Furthermore, the sliding engagement structure between the guide groove on the bottom surface of the fixed plate and the guide block on the connecting plate achieves a precise and stable vertical guiding effect for the hot-pressing assembly. During the heat-sealing process driven by the electric push rod, the guide block slides along the guide groove, effectively limiting the lateral displacement of the hot-pressing assembly. This ensures precise alignment between the upper and lower hot-pressing plates, preventing misalignment that could lead to heat-sealing position deviations or uneven stress. This significantly improves the accuracy and quality of the heat-sealing process, while also enhancing the stability of the hot-pressing assembly during operation and extending the equipment's service life.

[0027] Embodiment

[0028] As Figure 1 and Figure 2 As shown, the heat-sealing control device for an automatic packaging machine proposed by the present utility model includes: a base 1, and two conveying components 2 for conveying packaging bags are fixedly arranged on the upper surface of the base 1. The conveying components 2 include conveying rollers, conveying belts and motors, and can automatically convey the packaging belts.

[0029] Furthermore, a frame 3 is fixedly arranged on the upper surface of the base 1, and the frame 3 is arranged in a "冂" - shaped structure, which can provide stable support. Sliding grooves 8 are respectively opened on both sides of the frame 3, and sliders 9 are slidably arranged inside the sliding grooves 8, which can make the sliders 9 move stably according to the direction of the sliding grooves 8. The sliders 9 are fixedly connected to a fixing plate 5, which can guide the fixing plate 5 and make its movement more stable. And the frame 3 is located between the conveying components 2. An electric push rod 4 is fixedly installed on the upper surface of the frame 3. The output end of the electric push rod 4 penetrates through the frame 3 and extends to be connected with a fixing plate 5. The output end of the electric push rod 4 can push the fixing plate 5 to move stably vertically up and down. A guiding groove 10 is opened on the bottom surface of the fixing plate 5, and a guiding block 11 is slidably arranged inside the guiding groove 10. The guiding block 11 is fixedly connected to a connecting plate 61, thereby limiting the connecting plate 61 and ensuring the stability of the movement.

[0030] In addition, a lower hot pressing plate 7 is arranged between the conveying components 2, which can hot-press the lower side of the packaging bag. The lower hot pressing plate 7 is fixedly connected to the frame 3, and the lower hot pressing plate 7 is located directly below the fixing plate 5.

[0031] As Figure 3 and Figure 4 As shown, a hot-pressing assembly 6 for heat sealing is provided on the fixed plate 5. The hot-pressing assembly 6 includes a connecting plate 61. An upper hot-pressing plate 62 is fixedly provided on the bottom surface of the connecting plate 61, and the upper hot-pressing plate 62 is located directly above the lower hot-pressing plate 7, which can heat seal the packaging bag. A set of first connecting seats 63 are fixedly provided on both sides of the connecting plate 61. A linkage rod 64 is rotatably connected to the first connecting seat 63 through a shaft. One end of the linkage rod 64 is rotatably connected to a second connecting seat 65 through a shaft.

[0032] Furthermore, the hot press assembly 6 also includes a set of fixed frames 66 fixedly mounted on both sides of the electric push rod 4. A threaded rod 67 is rotatably mounted between the fixed frames 66 via bearings. One end of the threaded rod 67 passes through the fixed frame 66 and extends to be connected to a rotating cap 12, which facilitates the rotation of the threaded rod 67 by the rotating cap 12. A threaded sleeve block 68 is threadedly fitted onto the outer wall of the threaded rod 67, which allows the threaded sleeve block 68 to move stably through the threaded engagement. A sleeve block 69 is movably fitted onto the outer wall of the threaded rod 67. The threaded sleeve block 68 and the sleeve block 69 are set in an "H" shape, which allows them to slide and connect with the fixed frame 66, improving the stability of movement. The sleeve block 69 is fixedly connected to the fixed frame 66. A spring 610 is fitted onto the outer wall of the threaded rod 67. One end of the spring 610 is fixedly connected to the threaded sleeve block 68, and the other end of the spring 610 is fixedly connected to the sleeve block 69, which can adjust the pressure of the upper hot press plate 62 and prevent excessive pressure.

[0033] In this embodiment, when using the heat-sealing control device for an automatic packaging machine, the packaging bag is first placed on one of the conveying components 2 on the base 1, and the conveying component 2 drives the packaging bag forward. When the packaging bag moves into the frame 3 and is located above the lower heat-pressing plate 7 directly below the electric push rod 4, the conveying component 2 stops conveying.

[0034] At this time, if the packaging bag material and thickness are different, the operator can rotate the rotating cap 12 to drive the threaded rod 67 to rotate. Since the threaded rod 67 is threadedly connected to the threaded sleeve block 68, the threaded sleeve block 68 will move axially on the threaded rod 67, thereby changing the compression degree of the spring 610, and thus adjusting the pressure applied by the heat-sealing assembly 6 during heat sealing.

[0035] After the pressure adjustment is completed, the electric push rod 4 is activated, and its output end pushes the fixed plate 5 downward. During the downward movement of the fixed plate 5, the guide block 11 in the guide groove 10 on the bottom surface of the fixed plate 5 slides along the guide groove 10, providing precise and stable vertical guidance for the hot pressing assembly 6, ensuring that the hot pressing assembly 6 does not shift laterally when moving downward. The upper hot pressing plate 62 in the hot pressing assembly 6 gradually approaches the lower hot pressing plate 7. When it contacts the packaging bag, under the pressure adjusted by the spring 610, the upper hot pressing plate 62 and the lower hot pressing plate 7 heat-seal the packaging bag. After heat sealing is completed, the electric push rod 4 drives the hot pressing assembly 6 to move upward and reset, and the conveying assembly 2 is restarted to continue conveying the heat-sealed packaging bag.

[0036] 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.
