Description

Technical Field

[0001] This utility model relates to the field of rice packaging technology, specifically to a rice packaging sealing device. Background Technology

[0002] Rice packaging sealing equipment is a key piece of machinery used in the rice processing and packaging process. Its main function is to fill rice into packaging bags and then seal them to ensure the freshness and quality of the rice are maintained. Rice packaging sealing equipment typically includes a conveyor system for transporting processed rice from one part of the production line to the packaging area. This is usually a system with a conveyor belt that automatically feeds the rice to the packaging machine. Secondly, the sealing machine is responsible for sealing the opening of the packaging bag, using different working principles such as heat sealing, cold sealing, and ultrasonic sealing.

[0003] A search revealed that patent application number 202420483935.9 discloses a rice packaging sealing device, including a base, a heating element, a sealing assembly, and a control knob. By setting a second fixed block and a second heating element with variable positions within the sealing assembly, the sealing assembly automatically adapts to packaging bags of different sizes. This solves the problem that existing sealing devices often struggle to adapt to irregularly shaped or varying thicknesses of packaging bags due to the fixed position of the heating strip, thus limiting the device's applicability. This rice packaging sealing device, by adapting to the shape of rice packaging bags, provides high flexibility, efficiency, and quality control, helping rice producers improve production efficiency, reduce costs, and ensure product consistency and quality.

[0004] The aforementioned application documents achieve the corresponding heat sealing of rice bags through the setting of various components. However, during the rice sealing process, the bag containing rice needs to be placed in a vacuum machine, and the heat sealing component inside the machine is used to efficiently seal the rice bag. However, during this process, the rice bag needs to be manually smoothed to ensure the squareness of the rice bag after vacuuming, so as to facilitate subsequent handling and stacking. However, the effect of manual smoothing is limited, and the automation efficiency is low. Once an error occurs, the remedial operation is cumbersome, resulting in low practicality.

[0005] Therefore, we propose a rice packaging sealing device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rice packaging sealing device that solves the problem of poor product quality after vacuuming due to the need for manual adjustment of the rice bag thickness in existing devices.

[0013] The pad can be adjusted to adjust the height of the rice bag, ensuring that the bag opening is centered on the lower support plate. This guarantees that the seal is always in the middle of the rice bag, ensuring the quality of the rice bag after vacuuming.

[0014] As a preferred embodiment of this utility model, the vacuum frame at the top of the vacuum chamber base is assembled with the chamber cover via a hinge shaft, and a sealing strip frame is assembled at the bottom edge of the chamber cover, and the chamber cover is pressed onto the top edge of the vacuum frame via the sealing strip frame.

[0015] The lid is designed for easy opening and closing, while the sealing strip ensures a good seal and quality during subsequent vacuuming.

The power module is connected to the lower heat sealing strip base and the upper heat sealing strip base, and the lower heat sealing strip base and the upper heat sealing strip base include a motor reciprocating drive mechanism and a hot pressing plate.

[0017] This utility model provides a rice packaging sealing device. It has the following beneficial effects:

[0018] This rice packaging sealing equipment, through the arrangement of various components inside the vacuum frame and lid, can use an electric cylinder assembly to drive the lower support plate and the upper pressure plate to move vertically, thereby adjusting the distance between them.
