[0002] In the rice packaging production industry, the efficiency and quality of the sealing process directly affect the storage safety and transportation reliability of the product. Existing rice packaging sealing devices generally suffer from the following shortcomings in practical applications: First, the lack of an effective limiting and guiding structure during transport makes the packaging bags prone to shifting or tipping, affecting the accuracy of the sealing position; second, the height of the heat-sealing plate is mostly fixed, making it difficult to flexibly adjust according to different packaging bag sizes, thus limiting the equipment's applicability; third, the adjustment method for the distance between the heat-sealing plate and the guide rollers is complex, failing to quickly adapt to the sealing needs of various packaging bag sizes, resulting in low production efficiency; fourth, the lack of a professional leveling and venting mechanism before sealing allows residual air inside the bag to easily cause uneven sealing and poor sealing effects.

[0003] To address the pain points of the existing technology, this utility model proposes a quantitative sealing device with a reasonable structural design, flexible adjustment, and multiple functions. Through the synergistic effect of multiple components, it effectively improves the efficiency and quality of rice packaging sealing and has significant practical value.

Detailed Implementation

[0032] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Reference Figure 1-5 A quantitative sealing device for rice packaging includes a support frame 1, a conveyor belt 11, two lifting seats 3, two sliding frames 32, two heat sealing plates 321 and two vertical plates 33.

[0034] The conveyor belt 11 is set on the support frame 1, and the two lifting seats 3 are slidably installed on the support frame 1. Two mounting blocks 302 are fixedly installed on the top side of the support frame 1, and electric cylinders 301 are fixedly installed on the two mounting blocks 302. The telescopic ends of the two electric cylinders 301 are respectively fixedly connected to the corresponding lifting seats 3, and the height of the lifting seats 3 can be adjusted as needed.

[0035] Two mounting plates 21 are slidably installed on the support frame 1. A strip plate 2 is fixedly installed on the side of the two mounting plates 21 that are close to each other. The side of the two strip plates 2 that are close to each other is provided with a mounting groove. Multiple guide rollers 201 are vertically rotatably installed in the two mounting grooves. A rectangular opening is provided on the two mounting plates 21. Two vertical plates 33 pass through the corresponding rectangular openings, which can provide support and guidance for the rice packaging bags on the conveyor belt 11 and prevent them from tipping over during the conveying process.

[0036] Two sliding frames 32 are slidably mounted on corresponding lifting seats 3 respectively. Two heat sealing plates 321 are fixedly mounted on the side of the two sliding frames 32 that are close to each other. Two vertical plates 33 are slidably mounted on corresponding sliding frames 32 and are located on both sides of the support frame 1 respectively. A dual-axis motor 331 is fixedly mounted on one side of the support frame 1. A second lead screw 332 is axially fixedly connected to each of the two output shafts of the dual-axis motor 331. The two second lead screws 332 are threadedly connected to the corresponding vertical plates 33 respectively. The distance between the two vertical plates 33 can be adjusted as needed, thereby realizing the adjustment of the distance between the two heat sealing plates 321 and the distance between the guide rollers 201 on both sides.

[0037] A fixing block is fixedly installed on the bottom side of each of the two mounting plates 21. A first screw rod 22 is rotatably installed on the side of each fixing block that is far apart from each other. The two first screw rods 22 are respectively threadedly connected to the corresponding vertical plates 33. An adjusting wheel is fixedly sleeved on the side of each first screw rod 22 that is far apart from each other, so as to facilitate the adjustment of the initial distance between the two strip plates 2, thereby adapting well to the limiting and guiding of packaging bags of different sizes.

[0038] Two support plates 31 are fixedly installed on the side of each of the two lifting seats 3 that are close to each other. A common rotating shaft 311 is rotatably mounted on the two support plates 31 on the same side. A second mounting plate 312 is fixedly mounted on the rotating shaft 311. Two fixing brackets 313 are slidably mounted on the second mounting plate 312. The two fixing brackets 313 on the same second mounting plate 312 are symmetrically arranged around the axis of the corresponding rotating shaft 311. A squeezing roller 314 is rotatably mounted on each of the two fixing brackets 313. A spring 315 is fixedly mounted on each of the two fixing brackets 313. Both springs 315 are connected to the second mounting plate 312. The two support plates 31 on the rear side are fixedly connected, and each of them is equipped with an adjusting motor 316. The output shafts of the two adjusting motors 316 are axially fixedly connected to the corresponding rotating shafts 311. They can control the two mounting plates 312 to drive the corresponding two fixed frames 313 to rotate, thereby controlling the squeezing rollers 314 on both sides to flatten the position of the rice packaging bag to be sealed and squeeze out some of the air in the packaging bag, so as to facilitate the sealing operation by the heat sealing plate 321. The adjusting motors 316 are servo motors, which can ensure the synchronicity and accuracy of the movement of the squeezing rollers 314 on both sides.

[0039] Specifically, in order to prevent the vertical plate 33 from disengaging from the sliding frame 32, a limit block is fixedly installed on the top side of the vertical plate 33.

[0040] Specifically, in order to ensure that the height of the conveyor belt 11 does not change due to its own weight when conveying rice packaging bags, thereby ensuring its stability, a pallet is fixedly installed on the support frame 1, and the pallet is in contact with the conveyor belt 11.

[0041] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0042] Working principle: First, the power is turned on. When the rice packaging bag is placed on the conveyor belt 11, the conveyor belt 11 moves the packaging bag forward. During this process, multiple guide rollers 201 on both sides support and guide the packaging bag to ensure that it remains stable during the conveying process and avoids tipping or deviation. At the same time, the electric cylinder 301 adjusts the height of the lifting seat 3 according to actual needs, so that the heat sealing plate 321 can adapt to packaging bags of different specifications.

[0043] When the rice packaging bag reaches between the two heat-sealing plates 321, the second lead screw 332, controlled by the dual-axis motor 331, drives the two vertical plates 33 to adjust the distance. This action simultaneously adjusts the distance between the heat-sealing plates 321 and between the guide rollers 201 on both sides. This design allows the device to flexibly handle packaging bags of different sizes and perform heat-sealing operations on packaging bags passing between the two heat-sealing plates 321, improving the applicability of the equipment. In addition, the first lead screw 22, with the cooperation of the fixed block, further fine-tunes the initial distance of the strip plate 2, thereby optimizing the guiding effect.

[0044] Before the sealing operation, when the packaging bag moves to the position between the two heat-sealing plates, the conveyor belt pauses slightly. At the same time, the servo motor drives the rotating shaft 311 to rotate, causing the mounting plate 312 to drive the fixing frame 313 to rotate. The squeezing roller 314 on the fixing frame 313 then smooths the packaging bag from bottom to top at the position to be sealed and squeezes out some of the air inside the bag. The function of the spring 315 is to ensure that the squeezing roller 314 is in close contact with the surface of the packaging bag and to provide a cushioning effect for the fixing frame 313, thereby improving the flatness and sealing effect of the sealing.

[0045] The presence of the pallet provides additional support for the conveyor belt 11, effectively preventing changes in the conveyor belt height caused by the weight of the packaging bag. This design ensures the stability of the entire conveying process, thereby improving the sealing accuracy and efficiency. Finally, the packaging bag, after the above steps, is sealed by the heat-sealing plate 321. The entire process is efficient and precise.

[0046] The present invention provides a detailed description of a quantitative sealing device for rice packaging. Specific embodiments have been used to illustrate the principle and implementation of the present invention. These embodiments are merely illustrative and are intended to aid in understanding the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
