[0019] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0020] like Figures 1 to 6As shown, a raw material cutting device for bubble bag production according to this embodiment includes a conveying assembly 1 and a cutting assembly 2. The conveying assembly 1 includes a bracket 11, a driver 12, a connecting rod 13, a moving portion 14, a first cutter 15, and a second cutter 16. The driver 12 is mounted on the bracket 11, with two drivers 12 positioned opposite each other at opposite ends of the connecting rod 13. A telescopic rod 121 of the driver 12 is connected to the connecting rod 13, thereby driving the connecting rod 13 up and down through the telescopic rod 121. The driver 12 can be a pneumatic cylinder. The moving portion 14 is connected to the connecting rod 13, and the moving portion 14 is connected to a track 122 on the driver 12, so that the connecting rod 13 can drive the moving portion 14 to move vertically along the track 122. The first cutter 15 is positioned above the second cutter 16. The width of the first cutter 15 decreases from the first end 131 to the second end 132 of the connecting rod 13, so that the blade of the first cutter 15 is inclined relative to the second cutter 16. During cutting, the first and second cutters make point contact. The first tool 15 and the second tool 16 are provided with a heating tube 3, so that the tools can be heated by the heating tube 3 to improve the cutting effect. The heating tube 3 extends along the length direction of the first and second tools, which can make the tools heat up quickly. The heating tube 3 can be an electric heating tube. The conveying assembly 2 includes a roller 4, which is arranged between the brackets 11 and parallel to the first tool 15. In the above technical solution, the bubble bag material is introduced between the first and second tools by the roller 4, and the connecting rod 13 is driven downward by the driver 12, so that the moving part 14 drives the first tool 15 downward to cut the material. Since the width of the first tool 15 is gradually changed, it is easier to cut; in addition, the tool temperature can be increased by the heating tube 3, thereby improving the cutting effect. Through the above technical solution, it is possible to facilitate the cutting of raw materials and improve the cutting effect.

[0021] In this embodiment, the movable portion 14 has a coupling rod 17, and the connecting rod 13 is mounted on the coupling rod 17. The coupling rod 17 is mounted on a spring 18, which is located between the connecting rod 13 and the movable portion 14. When the movable portion 14 moves downward, the first cutter moves downward. When cutting, the force applied to the first cutter is transmitted to the spring 18 for buffering. The first cutter 15 is mounted on a cutter holder 18, and both ends of the cutter holder 18 are connected to the movable portion 14. This allows both sides of the cutter holder 18 to be driven by the movable portion 14 simultaneously, making its movement more stable.

[0022] In this embodiment, the roller 4 includes a main body 41, which is provided with a groove 42. A limiting assembly 5 is provided in the groove 42. The limiting assembly 5 can position the raw material, thereby facilitating the rolling discharge of the main body 41. The limiting assembly 5 includes an expansion portion 51, a movable portion 52, and a cover plate 53. The expansion portion 51 is provided in the groove 42, the movable portion 52 is provided above the expansion portion 51, and the cover plate 53 is provided on the movable portion 52. The movable portion 52 has a pressing member 521 and a mounting groove 522. The pressing member 521 is provided corresponding to the through hole 531 of the cover plate 53. The mounting groove 522 is provided with a spring 43, which abuts against the cover plate 53. Through the above technical solution, when the raw material roll 10 is sleeved on the main body 41, the expansion of the expansion portion 51 can push the movable portion 52 outward, driving the pressing member 521 to push out of the through hole 531, thereby pressing the raw material roll. The mounting groove 522 is provided with a screw hole 523. The locking member 6 passes through the cover plate 53 and the spring 43 and locks into the screw hole 523, thereby facilitating the positioning of the spring 43. The expansion portion 51 has an air cavity 511, which communicates with the air flow channel 411 of the main body 41. The air flow channel 411 is connected to an external air source device. The air source device extracts or delivers air, thereby controlling the deflation or inflation of the expansion portion 51. The groove 42 is strip-shaped and extends axially along the roller 4, thereby increasing the length of the limiter assembly 5 and increasing its contact area with the raw material roll.

[0023] The raw material cutting device for bubble bag production of this embodiment can facilitate cutting of raw materials and improve cutting effect; in addition, the raw material roll can be limited by the roller to facilitate the unwinding of the raw material roll.

[0024] It should be noted that the above preferred embodiments are merely illustrative of the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to fall within the scope of protection of the present invention.
