Description

Technical Field

[0001] This utility model relates to the field of edge sealing device technology, and in particular to an adjustable hot melt edge sealing device based on packaging design. Background Technology

[0002] In the modern packaging industry, sealing devices for bag-making machines are one of the key pieces of equipment in the production of various bag products such as plastic bags, self-sealing bags, and food bags. These devices process raw materials into bags of a predetermined shape through a series of automated processes, including cutting and heat-sealing of plastic rolls. They are widely used in various industries such as food, daily chemicals, and pharmaceuticals, playing a vital role in ensuring product safety, extending shelf life, and enhancing the aesthetics of packaging.

[0003] Traditional hot-melt sealing devices rely primarily on hot-melt technology, where heating elements locally melt the sealing material, followed by pressure to bond the materials together and seal the bag. However, a key issue in this process is the increasing demand for packaging bags of different sizes and shapes due to market diversification. Existing hot-melt sealing devices struggle to keep up with this demand. Specifically, traditional devices are often designed for fixed sizes or offer only limited adjustment ranges. This necessitates significant time spent on mechanical adjustments or changing specialized molds when switching between different bag sizes, resulting in inefficiency, increased production costs, and downtime.

[0004] Therefore, there is a need to provide an adjustable hot melt sealing device based on packaging design. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable hot melt sealing device based on packaging design to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable hot melt sealing device based on packaging design, comprising:

[0007] A support base is provided with a mounting shell. An opening is provided on one side of the mounting shell. A cylinder is mounted on the side of the mounting shell corresponding to the opening. The cylinder is connected to a connecting plate via a piston rod. A mounting plate is provided on the side of the connecting plate away from the cylinder. Two upper heating blocks are mounted on the side of the mounting plate away from the cylinder. The two upper heating blocks are arranged in parallel. A cutter is mounted on the mounting plate between the two upper heating blocks. Two lower heating blocks are mounted on the side of the mounting shell corresponding to the opening. The two lower heating blocks are arranged opposite to the two upper heating blocks and are respectively arranged on the two sides of the opening.

[0008] An adjustment assembly includes a dual-axis motor, a bidirectional screw, a limiting plate, and a telescopic guide rod. The dual-axis motor is housed within a mounting housing. The output end of the dual-axis motor is provided with a bidirectional screw. The two ends of the bidirectional screw away from the dual-axis motor are respectively connected to the limiting plates via threads. The two limiting plates are mounted on a support base. Each of the two limiting plates is provided with a telescopic guide rod assembly at its end away from the bidirectional screw. The telescopic guide rod assembly is correspondingly connected to the limiting plate.

[0009] Furthermore, a receiving plate extends from the side of the support base near the lower heating block;

[0010] A guide rail is provided on the side of the mounting plate away from the mounting shell. Two sliders are slidably arranged in the guide rail, and the two sliders are arranged opposite each other. A fixed rod is provided through each slider, and the fixed rod extends toward the receiving plate.

[0011] Furthermore, a spring is fitted onto the fixed rod.

[0012] Furthermore, the bottom of the fixed rod is provided with an anti-slip pad.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a dual-axis motor to drive a bidirectional screw to rotate, which in turn drives the limiting plate to move along the axial direction of the bidirectional screw. The distance between the two limiting plates can be flexibly adjusted according to the width of different packaging bags. This design can adapt to packaging of various sizes and specifications, and at the same time ensures that the packaging bag is always in the correct position during transportation, effectively preventing the packaging bag from shifting during transportation.

Detailed Implementation

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example: An adjustable hot melt sealing device based on packaging design, such as Figures 1-5As shown, the device includes a support base 1, a mounting shell 2, a cylinder 3, a connecting plate 4, a mounting plate 5, an upper heating block 501, a cutter 6, a lower heating block 7, a dual-axis motor 8, a bidirectional screw 9, a limiting plate 10, a telescopic guide rod 11, a guide rail 12, a slider 13, a fixed rod 14, a spring 15, and a receiving plate 16. The support base 1 serves as the basic support structure for the entire device, supporting components such as the mounting shell 2 and providing a stable platform for the device. The top of the support base 1 is connected to the mounting shell 2, which is used to install and accommodate the various functional components of the device. The interior of the mounting shell 2 has an opening for the packaging bag to pass through, providing space for the conveying and sealing operations of the packaging bag. The opening faces the upper heating block 501, the cutter 6, and the lower heating block 7. On one side, a cylinder 3 is vertically mounted downwards at the center of the top of the mounting shell 2. The piston rod of the cylinder 3 is connected to a connecting plate 4, and the bottom of the connecting plate 4 is connected to a mounting plate 5. Upper heating blocks 501 are symmetrically mounted on the bottom of the mounting plate 5. A cutter 6 is installed between two upper heating blocks 501 at the center of the mounting plate 5. The cutter 6 is used to cut the sealed packaging bag, separating it from the packaging bag material to form an independent packaging bag. Lower heating blocks 7 are symmetrically mounted on the lower front side of the mounting shell 2, corresponding to the lower position of the upper heating blocks 501. The upper heating blocks 501 and lower heating blocks 7 are located in front of the opening of the mounting shell 2. During operation, the upper heating blocks 501 and lower heating blocks 7 cooperate to heat the packaging bag passing through the mounting shell 2. The packaging bag with the opening is heat-sealed. A dual-axis motor 8 is horizontally installed at the center of the mounting shell 2. The output shaft of the dual-axis motor 8 is connected to a bidirectional screw 9. Two limit plates 10 are threaded to both ends of the bidirectional screw 9. The limit plates 10 are used to limit the packaging bag passing through the opening of the mounting shell 2. Both limit plates 10 are located at the top of the support base 1. Telescopic guide rod assemblies are symmetrically connected to the side walls of the limit plates 10 inside the mounting shell 2. The telescopic guide rod assemblies are used to guide and support the movement of the limit plates 10, ensuring the stability and accuracy of the movement of the limit plates 10. Each telescopic guide rod assembly can include two telescopic guide rods. Every two telescopic guide rods are arranged in parallel and are aligned with the limit plates 1 on the same side. The end of the mounting plate 5 furthest from the dual-axis motor 8 is connected to a guide rail 12 on the side furthest from the mounting shell 2. The direction of the guide rail 12 is the same as the direction of the cutter 6. Two sliders 13 are slidably connected to the guide rail 12, and the two sliders 13 can slide relative to each other on the guide rail 12. The sliders 13 have sliding holes, and a fixed rod 14 slides in the sliding holes. The fixed rod 14 plays a certain role in buffering and positioning during the sealing process to ensure the quality of the sealing. The fixed rod 14 extends along the downward pressing direction of the mounting plate 5. An anti-slip pad 17 is provided on the end of the fixed rod 14 furthest from the cylinder 3. The anti-slip pad 17 is mainly used to increase the friction between the fixed rod 14 and the packaging bag to play an anti-slip role. In addition, a spring 15 is sleeved on the fixed rod 14.A spring 15 is fitted onto the end of the fixed rod 14 between the anti-slip pad 17 and the slider 13. The spring 15 provides cushioning force during sealing to reduce the impact of uneven bag thickness or unstable movement on the sealing effect. Additionally, a receiving plate 16 extends from the support base 1 below the fixed rod. The receiving plate 16 receives the sealed and cut bags for easy collection and processing.

[0023] The working principle of this application is as follows: When the hot-melt sealing device is needed, the packaging bag to be sealed is first arranged to ensure that the opening direction of the packaging bag is consistent, which facilitates the conveying and sealing operation. Then, the position of the limiting plate 10 is adjusted according to the size of the packaging bag, and the dual-axis motor 8 is started. The output shaft of the dual-axis motor 8 drives the bidirectional screw 9 to rotate. Since the left and right ends of the bidirectional screw 9 are connected to the limiting plate 10 by threads, the limiting plate 10 will move along the axial direction of the bidirectional screw 9 under the rotation of the bidirectional screw 9. According to the width of the packaging bag, the distance between the two limiting plates 10 is adjusted so that the packaging bag can pass smoothly through the opening of the mounting shell 2 and will not deviate during the conveying process. When the limiting plate 10 moves, the telescopic guide rod 11 provides guidance and support to ensure the stability and accuracy of the movement of the limiting plate 10. The position of the fixed rod 14 is adjusted according to the size of the packaging bag. The fixed rod 14 on the slider 13 is manually slid left and right to adapt the position of the fixed rod 14 to the sealing position of the packaging bag. The fixed rod 14 plays a certain role in buffering and positioning during the edge sealing process. By adjusting its position, the quality of edge sealing can be guaranteed.

[0024] The open end of the packaging bag is placed into the opening of the mounting shell 2, positioning the bag between the upper heating block 501 and the lower heating block 7, with both sides of the bag tightly against the limiting plate 10. The piston rod of the cylinder 3 extends downwards, causing the connecting plate 4 and the mounting plate 5 to move downwards. The upper heating block 501 and the cutter 6 at the bottom of the mounting plate 5 move downwards together with the mounting plate 5, ensuring full contact and engagement between the upper heating block 501 and the lower heating block 7 to perform heat-sealing of the packaging bag.

[0025] After the sealing is completed, the cutter 6 continues to move downwards, cutting the sealed packaging bag to separate it into individual bags. During the sealing process, the fixing rod 14 contacts the packaging bag to fix it in place, while the spring 15 provides cushioning force to reduce the impact of uneven packaging bag thickness or unstable movement on the sealing effect.

[0026] After the sealing and cutting are completed, the piston rod of cylinder 3 retracts upward, causing the connecting plate 4 and mounting plate 5 to move upward. The upper heating block 501 and the cutter 6 leave the packaging bag, and then the sealed and cut packaging bag can be taken out from the opening of the mounting shell 2.

[0027] Repeat the above steps to complete the heat-sealing process for the next packaging bag.

[0028] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
