Description

Technical Field

[0001] This utility model relates to automatic vegetable packaging equipment, specifically an automatic vegetable packaging machine. Background Technology

[0002] In traditional vegetable packaging processes, each step relies heavily on manual labor, such as manual bagging, sealing, weighing, and labeling. However, with the booming development of e-commerce and the continuous expansion of online vegetable sales, consumer demand for vegetables is increasing, posing numerous challenges to the traditional manual packaging model.

[0003] On the one hand, manual operation is inefficient and cannot handle a large number of vegetable packaging tasks in a short period of time. This often makes vegetable packaging a bottleneck in the entire supply chain, failing to meet the timeliness requirements of fast delivery and distribution. Moreover, long hours of repetitive manual labor can easily lead to fatigue, which may result in inconsistent packaging quality, such as loose seals or crooked labels, affecting the overall image of the product and the sales experience.

[0004] On the other hand, for fresh produce like vegetables, preservation is crucial. During packaging, if air circulation is poor inside the bag, the moisture produced by the vegetables' respiration cannot escape, easily accelerating spoilage and reducing their quality and shelf life. However, traditional manual packaging makes it difficult to ensure that each bag has adequate ventilation, and it lacks standardized and regulated operating procedures.

[0005] In view of the above problems, there is an urgent need for a vegetable packaging equipment with a high degree of automation, full functionality and the ability to ensure the freshness of vegetables, to replace the traditional manual packaging mode, improve the overall level of vegetable packaging, and meet the needs of market development. The automatic vegetable packaging machine of this utility model was developed based on this background. Utility Model Content

[0033] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] I. Working principle of this utility model:

[0035] This automatic vegetable packaging machine mainly includes several important components such as frame 1, feeding rack 2, photoelectric detection device 3, puncher 4, film feeding mechanism 5, bag maker 6, center sealing mechanism 7, end sealing mechanism 8, weighing platform 9, and labeling machine 10. All parts work together to realize the fully automated operation of vegetables from transportation to packaging, weighing, and labeling.

[0036] Frame 1: As the supporting structure of the entire packaging machine, it bears all other components, ensuring that each component can be stably installed and operate normally. It is equipped with a second conveyor belt 101 for further transporting the pre-packaged vegetable products during the packaging process. A linear guide rail 102 is also provided on the side to drive the sealing mechanism 7 up and down. The height of the sealing mechanism 7 can be precisely adjusted via the linear guide rail 102, enabling it to accurately seal packaging bags of different thicknesses and sizes, ensuring sealing quality.

[0037] The loading rack 2 is movably mounted on one side of the frame 1. It has a horizontal conveyor belt and two side guide conveyor belts above it, forming a U-shaped conveying structure. The two parallel side guide conveyor belts can stably transport vegetables, preventing irregularly shaped vegetables from getting stuck during transport. The bottom is equipped with self-locking casters 202, allowing for easy position adjustment of the loading rack 2 according to actual usage scenarios and movement during equipment maintenance and cleaning. Simultaneously, the self-locking function ensures that the loading rack 2 remains in a fixed position during normal equipment operation, preventing unauthorized movement that could affect vegetable transport and packaging operations.

[0038] The photoelectric detection device 3 consists of an arched frame 301 and a photoelectric sensor 302. The arched frame 301 is set on both sides of the two side guide conveyor belts 201, and has an installation groove on its inner side. The photoelectric sensor 302 is installed in the installation groove. When vegetables are conveyed on the side guide conveyor belts 201 and pass under the photoelectric detection device 3, the photoelectric sensor 302 uses the photoelectric principle to detect the length of the vegetables and transmits the detection signal to the control system according to the preset spacing requirements. This control system then controls the conveying speed or start / stop of the side guide conveyor belts 201 on the feeding rack 2, thereby controlling the conveying position of the vegetables according to the set spacing and preparing for the subsequent accurate and orderly packing of the vegetables into packaging bags.

[0039] Perforator 4: Located on one side of the film feeding mechanism 5, during the film feeding process, the perforator 4 can punch ventilation holes of a fixed diameter on the film according to a set rule. Its punching principle can be achieved through mechanical stamping, laser punching, or other methods, allowing the vegetables inside the packaging bag to communicate with the outside, maintaining ventilation, reducing moisture accumulation in the vegetables, and extending their shelf life.

[0040] Film feeding mechanism 5 includes multiple circular rollers 501 for mounting film rolls and a guide roller group 502 for guiding the film. The circular rollers 501 can easily mount film rolls of different specifications, and through the cooperation of multiple circular rollers 501, the film can be released and unfolded smoothly. The guide roller group 502 further guides the direction of the film, ensuring that the film enters the subsequent processing stages accurately, such as passing through the perforator 4 and the bag maker 6.

[0041] Bag maker 6: Located above the guide roller assembly 502, it includes a flat plate 601 and vertical plates 602 on both sides of the flat plate 601. The vertical plates 602 are inclined, forming an acute angle with the flat plate 601. The flat plate 601 and the two vertical plates 602 form a U-shaped channel structure. After passing through the guide roller assembly 502, the film enters the U-shaped channel structure of the bag maker 6. Under the action of the film's own flexibility and the subsequent pushing action of the vegetables, the film is gradually shaped into a shape suitable for vegetable packaging, laying the foundation for the subsequent sealing operation.

[0042] The middle sealing mechanism 7 and the end sealing mechanism 8: The middle sealing mechanism 7 is located on one side of the frame 1. It heats and presses the two film edges that are stacked after the packaging bag is formed. The adhesive surface of the film is melted by heating, and then pressure is used to make them stick together tightly to achieve a seal on the side of the packaging bag. The end sealing mechanism 8 is located at the end of the frame 1. It is used to heat, press and cut the ends of the packaging bag. After the vegetables are put into the packaging bag, the two ends of the packaging bag are sealed. At the same time, the packaged vegetables are cut and separated from the subsequent film to ensure that each packaging bag is an independent and complete product.

[0043] Weighing platform 9: Equipped with a third conveyor belt 901, it receives packaged vegetable products and transports them to the weighing area for weight detection. Guide plates 11 are installed on both sides of the third conveyor belt 901. The guide plates 11 are mounted on the weighing platform 9 via two connecting rods 1101. The two connecting rods 1101 are rotatably connected, with one end of each rod 1101 rotatably mounted on the weighing platform 9, and the other end having an arc-shaped groove for sliding on the weighing platform 9. When the vegetable packaging bags arrive at the weighing platform 9, the guide plates 11 can be flexibly adjusted in position as needed through the ingenious connection structure of the connecting rods 1101, accurately positioning the packaging bags to the optimal weighing position and ensuring weighing stability.

[0044] Labeling machine 10: Located on one side of the weighing platform 9, after the vegetable packaging bags are weighed, the labeling machine 10 will print labels according to preset information such as vegetable variety, weight, place of origin, production date, shelf life, etc., and accurately affix the labels to the packaging bags, completing the last process of the entire vegetable packaging process, so that the packaged vegetable products have complete identification information, which is convenient for subsequent sales, transportation and management.

[0045] II. Implementation Method:

[0046] First, place the frame 1 on a flat, stable surface, ensuring its levelness meets requirements to provide a stable foundation for the subsequent installation of other components. Next, install the feeding rack 2, photoelectric detection device 3, film feeding mechanism 5, bag maker 6, center sealing mechanism 7, end sealing mechanism 8, weighing platform 9, and labeling machine 10 in sequence according to design requirements. During installation, it is crucial to ensure the accurate positioning of each component. For example, the arched frame 301 of the photoelectric detection device 3 must be symmetrically and horizontally installed on both sides of the two side guide conveyor belts 201. The center sealing mechanism 7 and end sealing mechanism 8 must be tightly fitted with the linear guide rail 102 to ensure smooth vertical movement.

[0047] After completing the installation of each component, the electrical wiring is connected. This includes correctly connecting various sensors such as photoelectric sensor 302, motors driving the conveyor belts, motors for the punching machine, and heating elements in the sealing mechanism 7 and end sealing mechanism 8 to the control system to ensure normal signal transmission. Simultaneously, the entire equipment is powered on and tested to check if each component can operate normally. For example, check if the side guide conveyor belt 201, the second conveyor belt 101, and the third conveyor belt 901 can rotate smoothly, if the photoelectric detection device 3 can accurately detect the length of the vegetables and provide feedback, and if the punching machine 4 can properly punch ventilation holes. Any problems encountered are promptly investigated and adjusted.

[0048] Vegetable feeding operation

[0049] The vegetables to be packaged are placed on the two side guide conveyor belts 201 of the feeding rack 2. The packaging machine is started, and the side guide conveyor belts 201 begin to operate, carrying the vegetables towards the photoelectric detection device 3. During the conveying process, even vegetables with irregular shapes can pass through smoothly through the two parallel side guide conveyor belts without jamming, ensuring the continuity of feeding.

[0050] Vegetable length detection and conveying control

[0051] When the vegetables are conveyed to the area below the photoelectric detection device 3, the photoelectric sensor 302 detects the length information of the vegetables in real time and transmits the signal to the control system. Based on the preset vegetable spacing requirements, the control system calculates the subsequent conveying speed of the side guide conveyor 201 or whether to pause, and then controls the side guide conveyor 201 to operate according to the corresponding rules, so that vegetables of different lengths can be conveyed sequentially to the corresponding positions above the film feeding mechanism 5 at the set spacing, ready for bagging.

[0052] Film processing and bag making

[0053] The film roll is installed on the circular roller 501 of the film feeding mechanism 5. After the film is released from the circular roller 501, it is guided by the guide roller group 502 and first passes through the position of the perforator 4. The perforator 4 punches air holes of a fixed diameter on the film according to the set frequency and position. Then the film enters the U-shaped channel structure of the bag maker 6. Under the push of the vegetables and the shaping action of the film itself, it gradually forms a shape suitable for vegetable packaging, waiting for the vegetables to be filled in.

[0054] Sealing and cutting operations

[0055] After the vegetables enter the pre-formed packaging bag, as the bag continues to move forward on the second conveyor belt 101, it first passes through the center sealing mechanism 7, where the overlapping film edges on both sides of the bag are heated and pressed together to complete the center seal of the bag. Next, the bag reaches the end sealing mechanism 8, where it also performs heating and pressing operations to seal the ends of the bag and simultaneously cuts and separates the packaged vegetables from the subsequent film. Thus, the packaging process for a complete packaged vegetable product is finished.

[0056] Weighing and Labeling

[0057] The packaged vegetable products are conveyed via the second conveyor belt 101 to the third conveyor belt 901 of the weighing platform 9. The weighing platform 9 detects the weight information of the vegetables and transmits it to the control system. Subsequently, the weighed vegetable bags continue to be conveyed forward on the third conveyor belt 901 to the labeling machine 10. The labeling machine 10 prints labels according to preset information and accurately affixes the labels to the packaging bags, thus completing the entire automatic packaging, weighing, and labeling process for the vegetables. The packaged vegetable products can then enter subsequent warehousing, transportation, and other stages for sale.

[0058] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
