Description

Technical Field

[0001] This application relates to the field of bag making machine technology, specifically to a self-adhesive sealing ribbon bonding device for a bag making machine. Background Technology

[0002] In the plastic bag manufacturing industry, bag making machines are one of the key pieces of equipment for improving production efficiency and reducing costs. However, in the traditional bag making process, the sealing process generally relies on manual operation or simple semi-automatic mechanical devices.

[0003] First, manual sealing is not only labor-intensive but also requires highly skilled operators. Since the sealing quality largely depends on the operator's proficiency and experience, it is difficult to guarantee the consistency and stability of the sealing. At the same time, manual sealing is relatively slow and cannot meet the needs of large-scale, high-efficiency production. Second, although semi-automatic sealing machines reduce the intensity of manual labor to some extent, their degree of automation is limited and still requires manual assistance for positioning and calibration. This not only increases the complexity of operation but also makes it easy for human factors to cause problems such as sealing position deviation and weak adhesion. Especially when making plastic bags with self-adhesive seals, the sealing quality is difficult to guarantee effectively due to the lack of precise positioning devices and control mechanisms. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Please see Figure 1 , Figure 2 and Figure 3 The self-adhesive sealing ribbon bonding device of the bag making machine in this embodiment includes a processing frame 1, and a conveying mechanism 2 is provided at the right end of the processing frame 1.

[0042] The conveying mechanism 2 includes two conveying plates 201, with a drive roller 202 rotatably connected between the two conveying plates 201 and multiple driven rollers 203 rotatably connected between the two conveying plates 201. The drive roller 202 and the driven rollers 203 are arranged at equal distances. Through the above arrangement, the purpose of conveying product bags can be achieved. Each driven roller 203 and the rear end of the drive roller 202 are fixedly connected to a pulley 7. The multiple pulleys 7 are connected by belt drive. Through the arrangement of the pulleys 7 and the belt, the synchronous rotation of the drive roller 202 and the driven roller 203 can be achieved. A motor 12 is installed on the front of the foremost conveying plate 201. The output end of the motor 12 is fixedly connected to one end of the drive roller 202. Through the arrangement of the motor 12, the rotation of the drive roller 202 can be powered.

[0043] Please see Figure 1 , Figure 2 and Figure 4 The front of the conveyor plate 201 is equipped with a control host 13. The control host 13 can control the electrical components. The left side of the conveyor mechanism 2 is equipped with a positioning mechanism 3.

[0044] The positioning mechanism 3 includes a positioning frame 301. Photoelectric sensors 302 are installed on both the front and back of the positioning frame 301. A laser rangefinder 303 is installed on the inner top wall of the positioning frame 301. The photoelectric sensors 302 are installed on both sides of the conveyor belt to detect the edge of the bag. The laser rangefinder 303 is fixed on the positioning frame 301 to accurately measure the front end position of the bag.

[0045] The positioning mechanism 3 is equipped with an adhesive applicator 4 on its left side.

[0046] Please see Figure 1 , Figure 2 and Figure 5 The glue application mechanism 4 includes a glue application frame 401, a glue tank 402 fixedly installed at the top of the glue application frame 401, an adjustment rail 403 fixedly connected to one side of the glue application frame 401, a glue gun 404 slidably connected to the outer surface of the adjustment rail 403, a pump body 406 at the bottom of the glue tank 402, the input end of the pump body 406 fixedly connected to the bottom of the glue tank 402, and a hose 407 fixedly connected to the output end of the pump body 406. The other end of the hose 407 is fixedly connected to the glue gun 404. With the above configuration, glue can be applied to the surface of the bag, which facilitates the subsequent bonding of ribbons. An upwardly inclined replenishment tube 8 is fixedly connected to the top of the outer surface of the glue tank 402, which allows the user to replenish the glue. A heater 9 is fixedly installed on the outer surface of the glue tank 402, which heats the glue.

[0047] Please see Figure 1 , Figure 2 and Figure 6 The upper surface of the adjustment rail 403 is provided with a set of fixing holes 14. The fixing holes 14 make it easy for the user to adjust and fix the glue gun 404. The left end of the glue application mechanism 4 is provided with a tape supply mechanism 5.

[0048] The tape supply mechanism 5 includes a tape supply frame 501, and a tape supply shaft 502 and a set of guide wheels 503 are rotatably connected to the front of the tape supply frame 501. With the above arrangement, the purpose of continuously supplying tape can be achieved.

[0049] Please see Figure 1 , Figure 2 and Figure 7 The left side of the tape feeding mechanism 5 is provided with a pressing mechanism 6. The pressing mechanism 6 includes a pressing frame 601. A set of lower pressing rollers 602 are rotatably connected between the front and rear inner side walls of the pressing frame 601. A movable frame 603 is provided above the set of lower pressing rollers 602. A set of upper pressing rollers 604 are rotatably connected between the front and rear inner side walls of the movable frame 603. A cylinder 605 is fixedly installed at the top of the pressing frame 601. The output end of the cylinder 605 is fixedly connected to the lower pressing rollers 602. Through the setting of the upper pressing rollers 604 and the lower pressing rollers 602, the tape can be pressed onto the bag.

[0050] A testing frame 10 is fixedly installed on the left end of the processing frame 1, and a visual monitoring module 11 is installed on the top of the testing frame 10. The bonding quality can be detected by setting up the visual monitoring module.

[0051] The self-adhesive sealing ribbon bonding device of the bag-making machine in this embodiment, through its automated design, enables rapid conveying, precise positioning, gluing, ribbon feeding, and pressing of product bags, significantly improving production efficiency. Compared to manual sealing and semi-automatic sealing machinery, this device can greatly reduce manual operation, lower labor costs, and increase sealing speed to meet the needs of large-scale, high-efficiency production. It employs photoelectric sensor 302 and laser rangefinder 303 for precise positioning, ensuring the stability and accuracy of the bags during conveying. Simultaneously, the design of the gluing mechanism 4 and pressing mechanism 6 ensures that the ribbon is evenly and firmly bonded to the bag, avoiding problems such as sealing position deviation and weak bonding. This precise positioning and bonding mechanism makes the sealing quality more stable and reliable. By adding a visual monitoring module 11, this device can monitor the sealing quality in real time, promptly identifying and correcting potential problems. This intelligent monitoring method not only improves the controllability of the production process but also further ensures the stability and consistency of the sealing quality.

[0052] It should be noted that since multiple pulleys 7 are arranged linearly and connected by a belt drive, in order to increase the contact area between the pulleys 7 and the belt and enhance the belt tension and stability, a tensioning pulley needs to be added at an appropriate position on the belt. The design of the tensioning pulley can ensure that the belt maintains an appropriate tension during transmission, reduce slack and vibration, thereby improving the transmission efficiency and stability between the pulleys 7 and the belt.

[0053] The working principle of the above embodiment is as follows: First, the product bag is placed on the conveying mechanism 2, supported and conveyed by the active roller 202 and multiple driven rollers 203 between the two conveying plates 201. The active roller 202 is driven by the motor 12, which drives the driven rollers 203 to rotate synchronously through belt transmission, thereby achieving smooth conveying of the product bag. As the product bag is conveyed, the positioning mechanism 3 starts to work. The photoelectric sensors 302 on the front and back of the positioning frame 301 detect the edge of the bag to ensure the stability of the bag during the conveying process. At the same time, the laser rangefinder 303 on the inner top wall of the positioning frame 301 accurately measures the position of the front end of the bag, providing accurate positioning information for subsequent glue application and ribbon bonding. When the bag reaches the glue application mechanism 4, the pump body 406 delivers the glue liquid in the glue tank 402 to the glue gun 404 through the hose 407. The glue gun 404 slides on the adjusting rail 403 and applies glue evenly to the surface of the bag according to the preset glue application path. The fixing hole 14 on 403 allows the user to precisely adjust and fix the position of the glue gun 404 to ensure the accuracy and consistency of glue application. After glue application, the bag continues to be conveyed to the tape supply mechanism 5. The tape supply shaft 502 on the tape supply frame 501 releases the tape and guides it to adhere to the surface of the bag coated with glue through a set of guide wheels 503. Finally, the bag enters the pressing mechanism 6. The cylinder 605 drives the upper pressure roller 604 to descend, working together with the lower pressure roller 602 to press the tape tightly onto the bag. This design of the upper pressure roller 604 and the lower pressure roller 602 ensures a firm fit between the tape and the bag, avoiding problems such as seal position deviation and weak adhesion. The visual monitoring module 11 monitors the sealing quality in real time. Once a potential problem is detected, such as uneven sealing or tape deviation, an alarm will be issued immediately and the operator will be prompted to make adjustments. This intelligent monitoring method greatly improves the controllability of the production process and the stability of the sealing quality.
