Description

Technical Field

[0001] This utility model relates to the field of bamboo chopsticks packaging technology, and in particular to a packaging film installation structure for a bamboo chopsticks packaging machine. Background Technology

[0002] In automated bamboo chopstick packaging equipment, the installation and conveying of the packaging film rolls directly affect packaging quality and production efficiency. (Reference) Figure 4 Existing automatic packaging equipment for bamboo chopsticks typically includes a mounting base 1 for the packaging film roll 8, a bamboo chopstick material bin 12, and a sealing structure 13. After the packaging film strip 11 unfolds from the packaging film roll 8, it passes through the outlet of the bamboo chopstick material bin 12. The bamboo chopsticks then exit from the bamboo chopstick material bin 12 and enter the sealing structure 13 together with the packaging film strip 11 to complete the heat sealing. The packaging film roll 8 is generally fixed to the equipment support using a rotating mounting method. Limiting baffles are installed on both sides of the inlet of the sealing structure 13 to constrain the edges of the film roll and prevent axial displacement during the sealing process. However, different specifications of bamboo chopsticks require packaging film rolls of different widths (e.g., 20mm, 30mm, 40mm, etc.), and variations in the film roll width can cause a shift in its center position. In the prior art, the packaging film roll 8 limiting structure of the packaging film roll installation structure is usually fixed, which cannot adapt to the center position offset of film rolls of different widths. This causes the center line of the film roll to be unable to be precisely aligned with the feed port of the sealing structure. When the center of the film roll is not aligned with the conveying path, the packaging film belt is prone to skewing or wrinkling during the conveying process. This problem is especially obvious during high-speed packaging. Utility Model Content

[0003] This invention addresses the issue that existing packaging film roll installation structures cannot adapt to the center position offset of film rolls of different widths. It proposes a packaging film installation structure for bamboo chopsticks packaging machines, which features an adjustable design for the position of the packaging film roll, allowing it to align with the feed inlet of the sealing structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A packaging film mounting structure for a bamboo chopsticks packaging machine includes a mounting base and a fixed mounting rod.
