Description

Technical Field

[0001] This utility model relates to the technical field of air column bag making machines, and in particular to a bag making machine for air column bags. Background Technology

[0002] Air column bags, also known as cushioning air column bags, are widely used in logistics packaging due to their excellent cushioning and shock absorption performance. In the hot pressing process of manufacturing air column bags in a bag-making machine, the telescopic frame in the hot pressing mechanism drives the hot pressing plate to complete the pressing action through the lifting rod, ensuring that the molten layer of the air column bag roll material is heated evenly. The hot pressing plate of the air column bag making machine is generally composed of multiple linearly arrayed ultrasonic heat-sealing plates. The distance between two ultrasonic heat-sealing plates is the width of a single air chamber on the air column bag after heat sealing. This width directly determines the air storage capacity and cushioning performance. Due to the wide variety of packaged goods, different cushioning scenarios sometimes require air chambers of different widths to meet different cushioning performance requirements. However, the hot pressing plate of the existing air column bag making machine is manually fixed, and the spacing between the linearly arrayed ultrasonic heat-sealing plates is adjusted. This is not only cumbersome to operate, but also makes it difficult to guarantee the equal spacing between two adjacent ultrasonic heat-sealing plates. Based on this, a bag-making machine for air column bags that can solve the above problems is proposed. Utility Model Content

[0003] To solve the technical problem of adjusting the spacing of ultrasonic heat-sealing plates, this utility model provides a bag-making machine for air column bags.

[0004] This utility model is achieved using the following technical solution: a bag-making machine for air column bags, including a worktable for the air column bag making machine. Multiple lifting rods are installed on the upper side of the worktable. The upper ends of the multiple lifting rods are connected to a pressing frame. Multiple secondary slide rails are fixedly connected to the lower side of the pressing frame. Multiple sliders are slidably connected to the multiple secondary slide rails. A pointer rod is fixedly connected to the lower side of each slider. An ultrasonic heat-sealing block is fixedly connected to the lower end of each pointer rod. A spacing adjustment mechanism is provided on one side of the pressing frame to simultaneously bring the multiple ultrasonic heat-sealing blocks closer or further apart at equal intervals.

[0005] As a further improvement to the above solution, the spacing adjustment mechanism includes a first slide rail fixedly connected to both sides of the pressing frame, a limit plate slidably connected between the two first slide rails, an array groove mechanism provided on the limit plate, and a limit plate driving mechanism for adjusting the stopping position of the limit plate provided on one side of the pressing frame.

[0006] As a further improvement to the above solution, the array slot mechanism includes multiple limiting slots opened on the limiting plate, and the multiple limiting slots are respectively paired with multiple pointer rods, with each pointer rod being movably connected to the inner side of the corresponding limiting slot.

[0007] As a further improvement to the above solution, the limiting plate driving mechanism includes a threaded sleeve fixedly connected to one side of the limiting plate, a threaded rod threaded onto the threaded sleeve, the threaded rod being rotatably connected to one side of the pressing frame, and an auxiliary rotating mechanism for rotating the threaded rod being provided at one end of the threaded rod.

[0008] As a further improvement to the above solution, the auxiliary rotation mechanism includes a handwheel fixedly connected to one end of the threaded rod.

[0009] As a further improvement to the above solution, when the handwheel is rotated clockwise, the threaded sleeve leaves the initial position, the limiting plate moves to one side along with the threaded sleeve, and multiple ultrasonic heat sealing blocks simultaneously diffuse and translate at equal intervals to both sides along the second slide rail, increasing the distance between two adjacent ultrasonic heat sealing blocks.

[0010] When the handwheel is rotated counterclockwise, the threaded sleeve moves in the opposite direction, and the limiting plate moves to the other side along with the threaded sleeve. The multiple ultrasonic heat sealing blocks move closer to the center at equal intervals along the second slide rail, and the distance between two adjacent ultrasonic heat sealing blocks becomes smaller.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a handwheel and multiple limiting slots on a limiting plate to push multiple ultrasonic heat sealing blocks to move closer or further away simultaneously. When processing air column bags of different sizes and needing to adjust the spacing between ultrasonic heat sealing blocks, it avoids the tediousness of manually setting the spacing of multiple ultrasonic heat sealing blocks one by one, achieving the advantages of simple spacing setting operation and convenient use.

[0013] 2. This utility model indirectly controls the distance between each ultrasonic heat-sealing block by opening multiple specially arranged limiting grooves on the limiting plate. Under the action of each pointer rod being held by the limiting groove, this method has the advantage of more precise control of the distance between two adjacent ultrasonic heat-sealing blocks, and has high wear resistance. After long-term use, the air stored in each air chamber of the manufactured air column bag can still be relatively balanced and stable. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Example:

[0022] Please combine Figures 1-3 This embodiment of a bag making machine for air column bags includes an air column bag making machine workbench 1. The air column bag making machine is a mature existing technology. Other core key components and equipment installed on its workbench are not within the scope of protection of this patent. Multiple lifting rods 3 are installed on the upper side of the air column bag making machine workbench 1. Four of the lifting rods 3 can push a pressing frame 4 up and down. In this embodiment, the lifting rods 3 are pneumatic lifting rods.

[0023] Please combine Figure 4 As shown, the upper ends of the four lifting rods 3 are connected to a pressing frame 4. The lower side of the pressing frame 4 is fixedly connected to two slide rails 12. Multiple sliders 14 are slidably connected to the two slide rails 12. In this embodiment, there are a total of eight sliders 14. The eight sliders 14 can correspond to an air column bag product with seven air chambers. In other embodiments, if an air column bag product with a different number of air chambers needs to be produced, different numbers of sliders 14 can be set according to the situation.

[0024] Please combine Figure 4 As shown, a pointer rod 15 is fixedly connected to the lower side of each slider 14, and an ultrasonic heat sealing block 2 is fixedly connected to the lower end of each pointer rod 15. Each ultrasonic heat sealing block 2 is electrically connected to an external power source. A spacing adjustment mechanism is provided on one side of the pressing frame 4 to make the eight ultrasonic heat sealing blocks 2 move closer or further away from each other at equal intervals.

[0025] Please combine Figure 3As shown, the spacing adjustment mechanism includes a first slide rail 11 fixedly connected to both sides of the pressing frame 4, a limit plate 6 slidably connected between the two first slide rails 11, an array groove mechanism on the limit plate 6, and a limit plate drive mechanism for adjusting the stopping position of the limit plate 6 on one side of the pressing frame 4.

[0026] Please combine Figure 4 As shown, the array groove mechanism includes eight limiting grooves 13 opened on the limiting plate 6. It should be noted that when the limiting plate 6 moves back and forth along the direction of the threaded rod 8, the limiting plate 6 can stop at any position. At this time, the distance between two adjacent ultrasonic heat sealing blocks 2 is equal.

[0027] Please combine Figure 4 As shown, eight limiting slots 13 and eight pointer rods 15 are respectively paired and set, and each pointer rod 15 is movably connected to the inner side of the corresponding limiting slot 13.

[0028] Please combine Figure 2 As shown, the limiting plate driving mechanism includes a threaded sleeve 7 fixedly connected to one side of the limiting plate 6, a threaded rod 8 threadedly connected to the threaded sleeve 7, the threaded rod 8 being rotatably connected to one side of the pressing frame 4, and an auxiliary rotating mechanism for rotating the threaded rod 8 being provided at one end of the threaded rod 8.

[0029] Please combine Figure 2 As shown, the auxiliary rotation mechanism includes a handwheel 5 fixedly connected to one end of the threaded rod 8. A rocker arm is provided on the handwheel 5, and the effect of saving effort is achieved by rotating the handwheel 5.

[0030] When the handwheel 5 is turned clockwise, the threaded sleeve 7 leaves the initial position, the limiting plate 6 moves to one side along the threaded sleeve 7, and multiple ultrasonic heat sealing blocks 2 simultaneously spread and translate to both sides at equal intervals along the second slide rail 12, and the distance between two adjacent ultrasonic heat sealing blocks 2 increases.

[0031] When the handwheel 5 rotates counterclockwise, the threaded sleeve 7 moves in the opposite direction, and the limiting plate 6 moves to the other side along the threaded sleeve 7. Multiple ultrasonic heat sealing blocks 2 move towards the center at equal intervals along the second slide rail 12, and the distance between two adjacent ultrasonic heat sealing blocks 2 becomes smaller.

[0032] The implementation principle of a bag-making machine for air column bags in this application embodiment is as follows: When it is necessary to adjust the distance between two adjacent ultrasonic heat-sealing blocks 2, the threaded rod 8 is rotated by the handwheel 5, which drives the threaded sleeve 7 to move back and forth. At this time, under the limit of the first slide rail 11, the threaded sleeve 7 can drive the limiting plate 6 to move back and forth. When the limiting plate 6 moves back and forth, the limiting groove 13 opened on the limiting plate 6 can drive each ultrasonic heat-sealing block 2 to move through the pointer rod 15 inside it, thereby driving multiple ultrasonic heat-sealing blocks 2 to move closer or further away from each other at the same time.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
