Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a feeding guide auxiliary mechanism. Background Technology

[0002] Traditional feeding methods often rely on manual operation, where materials are manually fed into the machine. This method is inefficient, labor-intensive, and has high labor costs.

[0003] The public account is " CN115339677A A Chinese invention patent discloses a card packaging machine, which includes a sheet unwinding roller and a film unwinding roller. A heating component and a thermoforming component are arranged sequentially on one side of the film unwinding roller. A first tension swing roller is provided between the sheet unwinding component and the creasing mold. A first detection probe is provided between the creasing mold and the horizontal and vertical sealing molds. A second tension swing roller, a film feeding wheel, and a second detection probe are arranged sequentially between the film unwinding component and the horizontal and vertical sealing molds.

[0004] However, the aforementioned card packaging machine still has the following drawbacks:

[0005] The first tension roller and the second tension roller can only achieve feeding at a single angle. They cannot change the feeding angle according to production needs, cannot meet various production requirements, and have poor adaptability.

[0006] Secondly, the tension roller is relatively simple and cannot achieve long-distance material conveying and precise control, resulting in low efficiency when processing large rolls of material and easy to cause unstable material tension.

[0007] Third, the design of the film material feeding wheel is relatively simple and cannot adapt to film materials of different thicknesses and materials. As a result, the film material is prone to wrinkles or damage during high-speed production, which affects the appearance and sealing of the packaging.

[0008] Fourth, the overall structure is relatively complex, making maintenance and cleaning more difficult, which increases the labor intensity of operators and also affects production efficiency and the service life of the machine.

[0009] Therefore, it is necessary to improve these technical issues. Utility Model Content

The fixed guide roller is fixed on the fixed plate, the rotating guide roller is rotatably fixed on the fixed plate, the fixed plate is provided with a guide slide rail, and the movable guide roller is fixedly set on the guide slide rail.

[0012] By adopting the above technical solution, the feeding and guiding auxiliary mechanism can be adjusted according to the width and shape of the material, realizing multi-angle and multi-tension conveying of the material, thus improving the adaptability and flexibility of the feeding and guiding auxiliary mechanism. In addition, the guiding device can easily adjust the position and direction of the guide rollers, simplifying the adjustment process. Furthermore, the position of the moving guide roller and the angle of the rotating guide roller can be adjusted independently, making maintenance and replacement of parts more convenient, reducing maintenance time and costs.

Simultaneously, the second limiting sleeve and the rotating fixed sleeve enhance the structural stability, ensuring the feeding stability of the rotary guide roller under high-speed or heavy-load conditions. The second rotating sleeve can adjust the feeding angle to adapt to different production needs, simplifying maintenance and component replacement and reducing downtime. Furthermore, the adaptability of the guiding device is enhanced, enabling it to accommodate a wider range of material types and sizes, improving the adaptability and versatility of the feeding and guiding auxiliary mechanism, thus increasing production efficiency and reducing costs.

The threaded connection design allows for easy adjustment of the tightening force of the support nut, reducing wear and extending the service life of the fastener. At the same time, the detachable design of the fastener simplifies the maintenance and inspection process, reducing maintenance costs and time.

[0021] The aforementioned feeding guide auxiliary mechanism can be further configured as follows: the material placement device includes a material fixing roller and a placement disc. A rotating threaded sleeve is fitted around the outer periphery of the material placement device. The placement disc is located at one end of the rotating threaded sleeve near the fixing plate.
