A packaging machine for a bag opening mechanism of a zipper bag

Abstract

This utility model belongs to the field of packaging machine technology, and in particular to a bag opening mechanism for zipper bags in a packaging machine. It includes a first zipper seat, with a lifting guide shaft and a mini cylinder fixedly mounted on the top. A linear bearing is mounted on the surface of the lifting guide shaft. The lifting guide shaft and the mini cylinder are fixedly mounted with a cylinder push plate and a suspension bracket via a pneumatic rod at the output end. When a packaging bag is conveyed to this station, a suction cup opens the bag. The mini cylinder drives a zipper lever to insert into the bag opening. An ultra-thin cylinder extends, causing two inner and outer zipper levers to press the bag openings on both sides against the lower baffle. Two linkage guide rods insert into the inner and outer sliding blocks of the bag opening mechanism. Simultaneously, the inner and outer levers push the zipper bag open along with the opening sliders and sliding blocks. After reaching a specified distance, the ultra-thin cylinder retracts, driving the inner levers to engage and release the bag opening. The bag is then lifted back to its initial position by the mini cylinder, facilitating the opening of the zipper bag and increasing the ease of use of the device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2 This utility model provides the following technical solution: a bag opening mechanism for a packaging machine for zipper bags, including a first zipper seat 14, a lifting guide shaft 15 and a mini cylinder 18 fixedly mounted on the top of the first zipper seat 14, a linear bearing 16 mounted on the surface of the lifting guide shaft 15, a cylinder push plate 11 and a suspension bracket 7 fixedly mounted on the lifting guide shaft 15 and the mini cylinder 18 through a pneumatic rod at the output end, a slide rail support 4 fixedly mounted on the bottom of the cylinder push plate 11, an electric slide rail 1 fixedly mounted on the surface of the slide rail support 4, a push-pull slider 12 slidably mounted on the surface of the electric slide rail 1, a second sliding plate 21 fixedly mounted on the bottom of the push-pull slider 12, and a second sliding plate 21 mounted on the surface of the push-pull slider 12. There is a sliding bearing 20, and an ultra-thin cylinder 10 is set above the sliding bearing 20. A linkage guide rod 3 is fixedly installed on the top of the second sliding plate 21. The ultra-thin cylinder 10 is fixedly installed with a fisheye connector 5 through the air rod at the output end. A zipper lever 13 is slidably installed inside the electric slide rail 1. A first slider plate 2 is installed on one side of the surface of the push-pull slider 12. A cylinder retaining ring 19 is installed on one side of the first slider plate 2. A movable rod 24 is set on the lower side of the zipper lever 13. A moving block 23 is movably installed on the surface of the movable rod 24. A sliding block 22 and a movable block 25 are fixedly installed on the left and right sides of the surface of the movable rod 24, respectively. A clamping assembly 26 is installed on the right end of the movable rod 24.

[0020] This device is installed at the top of the bag opening mechanism and is used to open zipper bags. When the equipment is working, a trolley traction device transports the packaged bag to this station. The bag opening suction cup opens a gap in the bag, and a mini cylinder 18 drives the zipper lever 13 to insert into the bag opening. An ultra-thin cylinder 10 extends, causing the inner and outer zipper levers 13 to press the bag openings on both sides against the lower baffle. Two inner and outer linkage guide rods 3 insert into the inner and outer sliding blocks of the bag opening mechanism. Simultaneously, the inner and outer zipper levers 13 push the zipper bag open along with the opening slider and sliding block 22. Once the bag has been pushed open to a specified distance, the ultra-thin cylinder 10... The retraction drive engages the internal paddle to loosen the bag opening, and then, with the mini cylinder 18, it is raised to the initial position to facilitate opening the zippered bag, increasing the ease of use of the device. The cylinder connector 8 allows for easy connection between the zipper pull 13 and the fisheye connector 5, thus facilitating control of the zipper pull 13's movement via the ultra-thin cylinder 10. The cylinder support 6 and cylinder pin 9 allow the ultra-thin cylinder 10 to be mounted on the surface of the sliding bearing 20, ensuring the stability of the ultra-thin cylinder 10. The ease of installation is facilitated by the placement of mounting screws and connecting holes, allowing for easy connection and fixation between the second zipper seat 17 and the first zipper seat 14. The mounting holes also facilitate the installation and fixation of the second zipper seat 17 to the wall, making it easy to install the device in a suitable location. The presence of three mounting holes ensures the device's secure and reliable installation, as does the presence of three connecting holes, guaranteeing the reliability and secureness of the connection between the first zipper seat 14 and the second zipper seat 17. This contributes to the device's practicality and functionality. The rust-proof paint coating on the surfaces of the first zipper seat 14, second zipper seat 17, zipper lever 13, push-pull slider 12, second sliding plate 21, first slider plate 2, slide rail support 4, suspension bracket 7, and cylinder push plate 11 prevents rusting and extends the device's lifespan. The curved shape of the zipper lever 13 allows for easier opening of the zipper bag. All electrical components in this device are powered by an external power source.

[0021] In one aspect of this embodiment, the arrangement of mounting screws and connecting holes facilitates the connection and fixation of the second zipper seat 17 and the first zipper seat 14. The arrangement of mounting holes facilitates the installation and fixation of the second zipper seat 17 to the wall, thereby making it easier to install the device in a suitable position. Furthermore, the presence of three mounting holes ensures the firmness and reliability of the device's installation. Additionally, the presence of three connecting holes ensures the reliability and firmness of the connection between the first zipper seat 14 and the second zipper seat 17, which is beneficial for ensuring the practicality and functionality of the device.

[0022] In one aspect of this embodiment, the setting of the cylinder connector 8 facilitates the installation and connection of the zipper lever 13 and the fisheye connector 5, thus making it easy to control the movement of the zipper lever 13 by the ultra-thin cylinder 10. The setting of the cylinder support 6 and the cylinder pin 9 facilitates the installation of the ultra-thin cylinder 10 on the surface of the sliding bearing 20 by the cylinder support 6 and the cylinder pin 9, which helps to ensure the ease of installation of the ultra-thin cylinder 10.

[0023] In one aspect of this embodiment, the anti-rust paint coating applied to the surfaces of the first zipper seat 14, the second zipper seat 17, the zipper lever 13, the push-pull slider 12, the second sliding plate 21, the first slider plate 2, the slide rail support 4, the suspension bracket 7, and the cylinder push plate 11 can prevent the device from rusting, thus extending its service life. Furthermore, since the zipper lever 13 is curved, it can more easily open the zipper bag.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
