[0002] In the packaging industry, the double-layer bonding process for packaging bags is crucial to product quality. Previous technologies had many shortcomings.

[0003] When traditional packaging bags are double-layered and bonded, it is difficult to accurately position the packaging bags, resulting in large deviations in the bonding position, poor product consistency, and high defect rate. Moreover, packaging bags of different materials and thicknesses lack compatibility, which limits the versatility of the equipment.

[0004] During transportation, packaging bags are prone to shifting and colliding with components, affecting product quality. In the heating and pressing process, due to the lack of effective preheating, the materials do not fuse well and the adhesion is not strong, making the packaging bags easy to break. In addition, the equipment structure design is poor, it occupies a lot of space, the maintenance and replacement of parts are inconvenient, there is a lot of manual operation, resulting in low production efficiency and high costs. This patent aims to solve these problems and improve the production level of the packaging industry.

[0005] This invention can improve the quality and effectiveness of packaging bags during the bonding process. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-layer adhesive device for preventing packaging bags from sticking together, comprising: a bracket, two conveyor belts installed inside the bracket, a positioning frame nested on the outer surface of the bracket, limit plates installed at both ends of the inner side of the bracket, two cylinders installed on the upper end of the positioning frame, a baffle and a heating plate respectively installed on the two cylinders, a pressing plate is provided between the two conveyor belts, and the bottom of the pressing plate is installed inside the bracket;

[0008] Several electric telescopic rods are installed on the inner side of the limiting plate. One end of each electric telescopic rod is connected to the inner side of the bracket. The upper end of the pressing plate is on the same horizontal plane as the upper end of the conveyor belt. The limiting plate is located above the conveyor belt. The heating plate is located at the front end of the baffle. The pressing plate and the heating plate are positioned opposite each other.

[0009] A further preferred embodiment: grooves are provided at both ends of the inner side of the bracket, one end of the electric telescopic rod is connected to the inner wall of the groove by bolts, and the limiting plate can be embedded inside the groove.

[0010] A further preferred embodiment: each of the limiting plates has a ball bearing embedded in its bottom, the bottom of the ball bearing protruding from the bottom of the limiting plate, the ball bearing and the limiting plate being movably connected, and the outer surface of the ball bearing contacting the upper end of the conveyor belt.

[0011] A further preferred embodiment: the heating plate and the cylinder output end are detachably connected, an adjustment plate is provided on one side of the baffle, an adjustment threaded rod is threadedly connected to the outer side of the baffle, and the baffle and the adjustment threaded rod are threadedly connected.

[0014] A further preferred embodiment: a support column is fixedly installed at the bottom of the pressing plate, and the bottom of the support column is fixedly installed inside the bracket.

[0015] Beneficial effects:

[0016] 1. By setting a limiting plate, which is connected to the bracket via an inner electric telescopic rod, the limiting plate's height is adjustable. It can flexibly adjust its position according to the specifications of different packaging bags to achieve precise positioning. The ball bearings embedded at the bottom of the limiting plate greatly optimize its contact mode with the conveyor belt. When transporting the packaging bags, the rolling of the ball bearings transforms the original sliding friction into rolling friction, significantly reducing the frictional resistance between the two. This not only allows the packaging bags to move more smoothly and stably on the conveyor belt, effectively avoiding problems such as packaging bag damage or transportation difficulties caused by excessive friction, but also greatly reduces the wear of the conveyor belt and the limiting plate itself, extending their service life. At the same time, when not in operation, the limiting plate can be embedded in the grooves at both ends of the inner side of the bracket, avoiding occupying too much space and making the overall structure of the equipment more compact. It is very suitable for production environments with limited space and provides space guarantee for efficient production.

[0017] 2. By incorporating a pressing plate, the double-layered portion of the packaging bag is ensured to be evenly stressed during the pressing process. This feature effectively reduces adhesion defects caused by uneven pressing, significantly improves the quality and effect of the bonding, greatly enhances the strength of the packaging bag, and reduces the risk of damage due to weak bonding. The ball bearings embedded at both ends of the bottom of the pressing plate can rotate flexibly during the pressing action, converting the sliding friction between the pressing plate and the conveyor belt into rolling friction, greatly reducing friction. This not only extends the service life of the pressing plate and the conveyor belt but also reduces energy consumption during equipment operation. In addition, the pressing plate is stably installed inside the support frame by support columns. This structural design gives it excellent stability during operation, enabling it to withstand greater pressure and ensuring smooth pressing operations, providing a solid guarantee for high-quality bonding work.

[0018] 3. By incorporating a baffle connected to a cylinder on the positioning frame, when the packaging bag is transported to the designated position, the cylinder rapidly pushes the baffle downwards, precisely blocking the packaging bag and stopping it in the accurate position. This provides a stable and reliable operating foundation for subsequent heating and pressing processes. This precise positioning function ensures the accuracy of the bonding position each time, greatly improving product consistency and quality stability, and effectively reducing the defect rate. Simultaneously, an adjustment plate is provided on one side of the baffle. The position of the adjustment plate can be flexibly adjusted via an adjusting threaded rod extending through the outer side. When the adjusting threaded rod is rotated, based on the threaded transmission principle, the adjustment plate can be moved horizontally, thereby adjusting the baffle position. This design allows the equipment to easily adapt to the positioning requirements of packaging bags of different sizes, significantly enhancing the equipment's versatility and adaptability, broadening its application range, and providing strong support for diverse production needs.

[0019] 4. This double-layer adhesive device for packaging bags incorporates a limiting plate and other structures. The limiting plate's position is flexibly adjusted via an electric telescopic rod for precise positioning. Bottom ball bearings reduce friction, extend component life, and save space. The arc-shaped design at both ends of the pressing plate ensures uniform pressing and improves adhesive quality. Ball bearings further reduce friction. Support columns ensure stable operation. The baffle and cylinder work together to achieve precise positioning, improving product consistency. The adjustable threaded rod allows for position adjustment, enhancing the device's versatility for packaging bags of different sizes. Together, these features ensure efficient and high-quality operation of the device. Attached Figure Description

[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0028] Please see Figure 1-6 In this embodiment of the present invention, a double-layer adhesive device for preventing packaging bags from sticking together includes: a support 1, two conveyor belts 2 installed inside the support 1, a positioning frame 3 nested on the outer surface of the support 1, a limit plate 4 installed at both ends of the inner side of the support 1, two cylinders 5 installed on the upper end of the positioning frame 3, a baffle 501 and a heating plate 502 respectively installed on the two cylinders 5, a pressing plate 6 is provided between the two conveyor belts 2, and the bottom of the pressing plate 6 is installed inside the support 1; a plurality of electric telescopic rods 401 are installed inside the limit plate 4, one end of the electric telescopic rod 401 is connected to the inner side of the support 1, the upper end of the pressing plate 6 is on the same horizontal plane as the upper end of the conveyor belt 2, the limit plate 4 is located above the conveyor belt 2, the heating plate 502 is located at the front end of the baffle 501, and the pressing plate 6 and the heating plate 502 are positioned correspondingly.

[0029] The packaging bag requiring double-layer bonding is placed on two conveyor belts 2. A limiting plate 4 is adjusted according to the bag's specifications to restrict its position during transport. The conveyor belts 2 rotate, moving the bag forward to prepare for the bonding operation. When the bag reaches the designated position, a cylinder 5 on the positioning frame 3 pushes a baffle 501 down, stopping the bag in the correct position for precise positioning and accurate bonding. After positioning by the baffle 501, another cylinder 5 pushes a heating plate 502 down, heating the area to be bonded to a temperature conducive to bonding, preparing for pressing. The cylinder 5 continues to lower the heating plate 502 until it overlaps with the pressing plate 6, which then presses the heated double layers of the bag together tightly. After pressing, the cylinder 5 retracts the heating plate 502 back to its initial position, and the conveyor belts 2 continue rotating. The packaging bag feeding device, which forms an adhesive layer, preheats the packaging bag using a heating plate 502, allowing the materials to fuse better during pressing. This improves the strength of the double-layer adhesion and reduces problems such as packaging bag breakage caused by weak adhesion. The positioning frame 3, cylinder 5, and baffle 501 accurately position the packaging bag, ensuring accurate positioning each time the adhesive is applied, thus improving product consistency and quality stability. This device can adapt to the double-layer adhesion needs of packaging bags of different materials and thicknesses by adjusting parameters such as the speed of the conveyor belt 2, the temperature of the heating plate 502, and the pressure of the pressing plate 6. It has strong versatility and adaptability. The various components in the device work in coordination through an electrical control system, realizing an automated process from packaging bag transportation, positioning, heating to pressing. This reduces manual operation, improves production efficiency, and lowers labor costs. The limiting plate 4 prevents the packaging bag from shifting during transportation, providing limitation and protection for the packaging bag, and also avoids damage caused by collisions between the packaging bag and other components.

[0030] In this embodiment of the utility model, grooves 101 are provided at both ends of the inner side of the bracket 1. One end of the electric telescopic rod 401 is connected to the inner wall of the groove 101 by bolts, and the limiting plate 4 can be embedded in the groove 101. A ball bearing 402 is embedded in the bottom of the limiting plate 4. The bottom of the ball bearing 402 protrudes from the bottom end of the limiting plate 4. The ball bearing 402 and the limiting plate 4 are movably connected, and the outer surface of the ball bearing 402 contacts the upper end of the conveyor belt 2.

[0031] The grooves 101 formed at both ends of the inner side of the bracket 1 provide installation positions for the electric telescopic rod 401. One end of the electric telescopic rod 401 is fixed to the inner wall of the groove 101 with bolts, which ensures the stability and reliability of the electric telescopic rod 401 during operation. When it is necessary to limit the packaging bag, the electric telescopic rod 401 is used to limit the packaging bag. The limiting plate 4 can be embedded inside the groove 101. When not in use, the limiting plate 4 can be stored in the groove 101 to avoid occupying too much space. When transporting the packaging bag, the limiting plate 4 extends out of the groove 101 to limit the packaging bag. The function is to prevent the packaging bag from shifting on the conveyor belt 2. A ball bearing 402 embedded in the bottom of the limiting plate 4 is movably connected to the limiting plate 4. When the conveyor belt 2 rotates and moves the packaging bag, the ball bearing 402 can rotate flexibly at the bottom of the limiting plate 4. Since the bottom of the ball bearing 402 protrudes from the bottom of the limiting plate 4 and contacts the upper end of the conveyor belt 2, the rolling of the ball bearing 402 reduces the frictional resistance between the limiting plate 4 and the conveyor belt 2 while limiting the packaging bag, allowing the packaging bag to move more smoothly on the conveyor belt 2. The electric telescopic rod 401 is connected to the inner wall of the groove 101 by bolts. This connection method makes the installation and disassembly of the electric telescopic rod 401 convenient, facilitating later maintenance and replacement, and improving the maintainability of the equipment. The design of the limiting plate 4 being embedded in the groove 101 allows the limiting plate 4 to be stored when not in use, reducing the space occupied by the device and making the entire structure of the equipment more compact. It is suitable for production environments with limited space. The setting of the limiting plate 4 can effectively limit the movement range of the packaging bag on the conveyor belt 2, prevent the packaging bag from deviating, and ensure the positional accuracy of the packaging bag during transportation and processing, thereby improving product quality and production efficiency. The presence of the ball bearing 402 changes the friction between the limiting plate 4 and the conveyor belt 2 from sliding friction to rolling friction, greatly reducing frictional resistance. This not only reduces the wear of the conveyor belt 2 and the limiting plate 4, extending their service life, but also reduces the energy consumption during equipment operation and improves energy utilization efficiency. Since the ball bearing 402 can rotate flexibly, it does not obstruct the normal transportation of the packaging bag while limiting it, ensuring that the packaging bag can move smoothly and steadily on the conveyor belt 2, avoiding problems such as damage to the packaging bag or poor transportation due to excessive friction.

[0032] In this embodiment of the utility model, the heating plate 502 and the output end of the cylinder 5 are detachably connected. An adjustment plate 503 is provided on one side of the baffle 501. An adjustment threaded rod 504 is threadedly connected to the outer side of the baffle 501. The baffle 501 and the adjustment threaded rod 504 are threadedly connected. A bearing 505 is embedded in the inner side of the adjustment plate 503. One end of the adjustment threaded rod 504 can be fixedly installed inside the bearing 505. The two ends of the pressing plate 6 are arc-shaped. A second ball bearing 601 is embedded in the bottom of both ends of the pressing plate 6. The bottom of the second ball bearing 601 protrudes from the bottom end of the pressing plate 6. The second ball bearing 601 is movably connected to the pressing plate 6, and the outer surface of the second ball bearing 601 contacts the upper end of the conveyor belt 2. A support column 602 is fixedly installed at the bottom of the pressing plate 6. The bottom of the support column 602 is fixedly installed inside the bracket 1.

[0033] The heating plate 502 is detachably connected to the output end of the cylinder 5. When the heating plate 502 is damaged, needs to be replaced with a different specification, or requires maintenance, it can be easily and quickly removed from the output end of the cylinder 5. During normal operation, the cylinder 5 drives the heating plate 502 down to the area of ​​the packaging bag to be glued for heating. After heating, it rises back to its original position. The adjustment of the baffle 501 and the adjusting plate 503 is as follows: the adjusting threaded rod 504 on the outside of the baffle 501 is threadedly connected to the baffle 501. A bearing 505 is embedded inside the adjusting plate 503. One end of the adjusting threaded rod 504 is fixedly installed inside the bearing 505. When the adjusting threaded rod 504 is rotated... Due to the threaded transmission principle, the adjusting threaded rod 504 moves back and forth on the baffle 501, thereby pushing the adjusting plate 503 to move horizontally, thus adjusting the position of the baffle 501 to meet the positioning requirements of packaging bags of different sizes. The bottom of the pressing plate 6 is fixedly installed inside the bracket 1 by the support column 602. When the packaging bag needs to be pressed, the electric telescopic rod 401 located inside the limiting plate 4 extends, pushing the pressing plate 6 upward. The two ends of the pressing plate 6 are arc-shaped, and the ball bearings 601 embedded at the bottom of both ends are movably connected to the pressing plate 6. The bottom of the ball bearings 601 protrudes from the bottom of the pressing plate 6 and contacts the upper end of the conveyor belt 2. The ball bearings 601 can flexibly press during pressing. The flexible rotation reduces friction between the pressing plate 6 and the conveyor belt 2, making the pressing action smoother. After pressing, the electric telescopic rod 401 retracts, and the pressing plate 6 descends back to its initial position. The detachable connection design of the heating plate 502 makes maintenance and replacement of the heating plate 502 simple and easy, reducing equipment maintenance costs and downtime, and improving equipment efficiency. The position of the baffle 501 can be flexibly adjusted by adjusting the threaded rod 504 and the adjusting plate 503, which can adapt to the precise positioning of packaging bags of different sizes and specifications, enhancing the versatility and adaptability of the equipment and expanding its application range. The arc design at both ends of the pressing plate 6 can better fit the packaging bag. The edges are designed to ensure that the double-layered parts of the packaging bag are evenly stressed during pressing, improving the quality and effect of the bonding and reducing bonding defects caused by uneven pressing. The setting of the ball bearing 601 converts the sliding friction between the pressing plate 6 and the conveyor belt 2 into rolling friction, which greatly reduces friction, reduces wear on the pressing plate 6 and the conveyor belt 2, extends their service life, and also reduces energy consumption during equipment operation. The pressing plate 6 is fixedly installed on the inner side of the bracket 1 by the support column 602. This structural design ensures the stability of the pressing plate 6 during operation, can withstand greater pressure, ensures the smooth progress of the pressing operation, and improves the reliability and durability of the equipment.

[0034] Working principle: First, the packaging bag to be bonded is placed on the two conveyor belts 2 inside the support 1. After the conveyor belts 2 start, the packaging bag moves forward by friction. During this process, the limiting plates 4 at both ends of the inner side of the support 1 play a role. The limiting plates 4 are connected to the support 1 through the electric telescopic rod 401 on the inner side. The ball bearing 402 at the bottom of the limiting plates 4 contacts the conveyor belt 2. The electric telescopic rod 401 can adjust the position of the limiting plates 4 according to the size of the packaging bag. The ball bearing 402 reduces the friction between the limiting plates 4 and the conveyor belt 2, ensuring that the packaging bag is transported smoothly and does not deviate. When the packaging bag reaches the designated position, the cylinder 5 on the positioning frame 3 connected to the baffle 501 is activated, pushing the baffle 501 down to block the packaging bag and achieve precise positioning. Subsequently, another cylinder 5 connected to the heating plate 502 is activated, and the heating plate 502 is lowered to heat the part of the packaging bag to be bonded, so that the material reaches the temperature for easy bonding. After heating is completed, the heating plate 502 continues to descend until it overlaps with the pressing plate 6. At this time, the electric telescopic rod 401 inside the limiting plate 4 extends, pushing the pressing plate 6 upward to press the double-layer part of the heated packaging bag together, completing the bonding. After pressing is completed, the heating plate 502 rises and resets under the drive of the cylinder 5, and the conveyor belt 2 starts running again, sending out the bonded packaging bag. In addition, the heating plate 502 and the output end of the cylinder 5 are detachably connected for easy maintenance and replacement. The adjustment plate 503 on one side of the baffle 501 can be adjusted in position by adjusting the threaded rod 504 to accommodate packaging bags of different sizes. The two ends of the pressing plate 6 are arc-shaped, and the ball bearing 601 at the bottom reduces friction with the conveyor belt 2. It is fixed to the inside of the bracket 1 by the support column 602 to ensure stability during pressing. The entire device coordinates the components through the electrical control system to automatically complete the packaging bag transportation, positioning, heating and pressing process.
