Description

Technical Field

[0001] This utility model relates to the field of air column bag production technology, and in particular to a cutting device for air column bag production. Background Technology

[0002] Air column bags are a new type of cushioning packaging material made from nylon co-extruded film and PE film through a heat-sealing process, filling the interior with air to form independent air columns. They possess excellent flexibility and cushioning properties, effectively protecting fragile items such as electronic products, glassware, and ceramics from collisions and vibrations during transportation. Compared to traditional foam and sponge packaging, they are more environmentally friendly and reusable.

[0003] Cutting is a crucial step in the production of air column bags. Products of different sizes and shapes require corresponding air column bags for packaging. Cutting allows continuously produced air column bag film to be processed into customized sizes that meet actual needs. Traditional air column bag cutting equipment needs to work in conjunction with transportation equipment to cut the air column bags during transportation. However, cutting and transportation are independent of each other. If an error occurs in the coordination between the two steps, it will lead to errors in the cutting dimensions of subsequent air column bags. Moreover, this error is not easy to detect. That is, when a cutting dimension problem is discovered, the equipment is still running, resulting in the production of a large amount of waste air column bags.

[0004] Based on this, a cutting device for the production of air column bags is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting device for the production of air column bags in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device for producing air column bags includes a limiting frame, a lifting plate slidably connected to the limiting frame, a blade connected to the lower end of the lifting plate, a rotary motor connected to the limiting frame via a motor frame, a rotating wheel connected to the output end of the rotary motor, a lever connected to the outer side of the rotating wheel, a bevel gear I connected to the lower end of the rotating wheel, a conveying roller disposed below the bevel gear I, a bevel gear II connected to one end of the conveying roller, and a transmission mechanism for driving the lifting plate to move up and down connected between the rotating wheel and the limiting frame.

[0008] Preferably, the transmission mechanism includes a slide, a connecting frame is connected to the slide, a slider is slidably connected to the slide, a slide rod is connected to the slider, and the slide rod is slidably connected to the lifting plate.

[0009] Preferably, there are two conveying rollers, which are rotatably connected to the connecting frame.

[0010] Preferably, the connecting frame is connected to the lower end of the limiting frame by a support column.

[0011] Preferably, the lifting plate has an inclined groove, and the slide rod is slidably connected to the inclined groove.

[0012] Preferably, a limiting piece is connected to the outside of the slider, vertical rods are connected to the upper and lower ends of the slider, a sliding groove is provided on the slide frame, and the vertical rods are slidably connected to the sliding groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application uses a rotating wheel and a lever connected to the outside of the rotating wheel to make the slider move horizontally. Combined with the gravity of the lifting plate, the blade can fall freely. Then, under the action of the lever, the lifting plate is raised, thereby enabling the blade to accurately cut the air column bag.

[0015] 2. This application adopts a bevel gear structure, in which bevel gear one and bevel gear two mesh with each other, so that the cutting and transportation of the air column bag are driven by the same rotary motor, which can effectively ensure stable coordination between cutting and transportation and avoid errors in cutting dimensions.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A cutting device for producing air column bags includes a limiting frame 1, a lifting plate 11 slidably connected to the limiting frame 1, and a blade 14 connected to the lower end of the lifting plate 11. When the blade 14 falls, it can cut the air column bag above the bottom end of the limiting frame 1. After cutting, the blade 14 immediately moves upward. The limiting frame 1 is connected to a rotary motor 3 through a motor frame 2. When air column bag cutting is required, only the rotary motor 3 needs to be started. The output end of the rotary motor 3 is connected to a rotating wheel 4, and a lever 5 is connected to the outside of the rotating wheel 4. The number of levers 5 is related to the number of times the lifting plate 11 moves up and down once during one rotation of the rotating wheel 4. A bevel gear 6 is connected to the lower end of the rotating wheel 4, and a conveying roller 9 is set below the bevel gear 6. One end of the conveying roller 9 is connected to a bevel gear 13. A transmission mechanism for driving the lifting plate 11 to move up and down is connected between the rotating wheel 4 and the limiting frame 1.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the transmission mechanism includes a slide 10, a connecting frame 7 connected to the slide 10, a slider 16 slidably connected to the slide 10, a slider rod 18 connected to the slider 16, and the slider rod 18 slidably connected to the lifting plate 11. When the slider 16 slides on the slide 10, the slider rod 18 also slides on the lifting plate 11.

[0025] Specifically, such as Figure 2 As shown, there are two conveying rollers 9, which are rotatably connected to the connecting frame 7. The air column bag is held between the conveying rollers 9, and can drive the air column bag to move when the conveying rollers 9 rotate.

[0026] Specifically, such as Figure 2 As shown, the connecting frame 7 is connected to the lower end of the limiting frame 1 by a support column 8, which improves the stability of the equipment structure.

[0027] Specifically, such as Figure 3 As shown, the lifting plate 11 has an inclined groove 12, and the slide rod 18 is slidably connected to the inclined groove 12. The inclination direction of the inclined groove 12 is related to the movement direction of the slider 16 after being moved by the lever 5. That is, when the slider 16 is moved by the lever 5, the lifting plate 11 will rise in height.

[0028] Specifically, such as Figure 3 As shown, a limiting piece 17 is connected to the outside of the slider 16, and vertical rods 19 are connected to the upper and lower ends of the slider 16. A slide groove 15 is provided on the slide frame 10, and the vertical rod 19 is slidably connected to the slide groove 15. By setting the limiting piece 17 and the vertical rod 19, the stability of the horizontal sliding of the slider 16 structure is improved, and the slider 16 structure is prevented from rotating under the action of the lever 5, ensuring that it can only move horizontally.

[0029] In summary, the cutting equipment for producing air column bags provided in this embodiment can transport the air column bags through the conveyor roller 9 when cutting the air column bags. The rotary motor 3 is started, and the rotary motor 3 drives the rotary wheel 4 and the bevel gear 6 to rotate. Since the bevel gear 6 can drive the conveyor roller 9 to rotate through the meshing bevel gear 13 when rotating, the conveyor roller 9 can transport the air column bag held in the middle to the cutting position.

[0030] When the rotating wheel 4 rotates, the lever 5 can move the slider 16 to slide on the carriage 10. When the slider 16 slides, the sliding rod 18 can drive the lifting plate 11 to rise. When the lifting plate 11 rises to the highest point, the lever 5 will separate from the slider 16 due to rotation. At this time, the lifting plate 11 will drop in height under the action of gravity, and work with the blade 14 to complete the cutting of the air column bag. When the next lever 5 contacts the slider 16, the lifting plate 11 will repeat the operation of rising in height and then falling freely to complete the cutting of the air column bag of a fixed length.

[0031] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
