Technical Field

[0001] This utility model relates to the field of vegetable packaging technology, and in particular to a plastic wrapping device for carrot packaging. Background Technology

[0002] Carrot packaging design is a comprehensive process, encompassing not only product protection and display but also brand image building and the integration of environmental protection concepts. High-quality carrot packaging first uses environmentally friendly, biodegradable, or recyclable materials, such as paper and biodegradable plastics, to reduce environmental burden and respond to the call for sustainable development. In terms of packaging structure, shock-proof and pressure-resistant designs are employed, such as internal foam netting, bubble wrap, or dividers, to ensure that the carrots are not crushed during transportation and storage, maintaining their crisp, juicy texture and intact appearance. To maintain freshness, the packaging may also include an internal preservation bag or use a ventilated design to regulate humidity and oxygen levels inside the packaging, slowing down moisture loss and nutrient depletion. Furthermore, the packaging will clearly label product information, including place of origin, production date, shelf life, storage recommendations, and consumption methods, making it easy for consumers to understand and store the carrots correctly.

[0003] Wrapping carrots in plastic wrap is a practical and efficient way to preserve their freshness. Utilizing the airtight nature of plastic wrap, it effectively locks in the carrots' moisture and freshness, preventing the intrusion of external air and bacteria, thus extending their shelf life. At the same time, the transparent or semi-transparent plastic wrap allows the carrots' vibrant color and plump shape to be clearly displayed, attracting consumers' attention. This packaging method is simple, quick, relatively low-cost, and easy to carry and store, making it a widely adopted carrot packaging solution in the market.

[0004] When packaging carrots, it is necessary to use plastic wrap to ensure their freshness. However, in the traditional method of packaging carrots with plastic wrap, manual wrapping is usually required. This method is not only time-consuming and labor-intensive, but also greatly reduces the tightness of the plastic wrap around the carrots, making it extremely inconvenient. Therefore, there is an urgent need for a plastic wrap wrapping device for carrot packaging to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a plastic wrap wrapping device for carrot packaging, which solves the problem that in the prior art, when packaging carrots with plastic wrap, manual wrapping is usually used, which is not only time-consuming and labor-intensive, but also greatly reduces the tightness of the plastic wrap wrapping on the carrots.

[0023] To make the objectives, technical solutions, and advantages 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.

[0024] Reference Figure 1-6A carrot packaging plastic wrapping device includes a frame 1. A drive motor 15 is bolted to one side of the frame 1, and a rotating rod 16 is rotatably connected to one side of the frame 1. A carrier plate 2 is fixedly connected to one end of the rotating rod 16, and an mounting sleeve 3 is fixedly connected off-center for mounting a plastic wrapping roller 4. A docking sleeve 7 is rotatably connected to the center of the carrier plate 2 via a rotating shaft for initial positioning of the carrot. The carrier plate 2 serves as the execution platform for the entire wrapping action, ensuring that the plastic wrap can be wrapped evenly and tightly. On the carrot, the other end of the rotating rod 16 passes through the side wall of the frame 1 and is connected to the output shaft of the drive motor 15. A mounting sleeve 3 is fixedly connected to the bearing disk 2 off-center, and is detachably connected to one end of the plastic wrapping roller 4, facilitating the replacement of plastic wrapping rollers of different specifications or types. A plastic wrapping roller 4 is provided on one side of the bearing disk 2, wrapped with plastic wrap 20, serving as the direct source of the plastic wrap. The plastic wrapping roller 4 is connected to the bearing disk 2 via the mounting sleeve 3 and rotates with the rotation of the bearing disk, achieving continuous supply and wrapping of the plastic wrap. One end of the plastic wrapping roller 4 is detachably connected to the mounting sleeve 3. A docking sleeve 7 is rotatably connected to the center of the bearing plate 2 via a rotating shaft. A bearing sleeve 9 is provided on one side of the docking sleeve 7. Arc-shaped clamping plates 17 are elastically connected to both sides of the inner side of one end of the bearing sleeve 9. These plates adapt to carrots of different diameters through elastic deformation and tightly clamp the carrots to ensure that they do not shake or fall off during the wrapping process. A connecting plate 10 is fixedly connected to the other end of the bearing sleeve 9, and a side plate 8 is fixedly connected to one side of the frame 1. A cylinder 11 is fixedly connected to one side of the side plate 8 by bolts, and the output shaft of the cylinder 11 passes through the side plate 8 and is fixedly connected to one side of the connecting plate 10. A plastic wrap 20 is wound on the plastic wrap wrapping roller 4, and a deformable wrapping rope 21 is embedded on the plastic wrap 20. The deformable wrapping rope 21 increases the friction between the plastic wrap and the carrot through its deformation ability, which improves the tightness and stability of the wrapping. At the same time, the deformable wrapping rope 21 can also adapt to the irregular shape of the carrot, ensuring that the plastic wrap can be tightly attached to the surface of the carrot.

[0025] Furthermore, a support frame 12 is slidably connected to the bottom inner side of the frame 1, and the support frame 12 is located at the bottom of the support sleeve 9. The support frame 12 can move synchronously with the movement of the support sleeve 9, providing an additional support platform for the carrot, ensuring the stability of the carrot during the winding process, and facilitating the collection of any possible plastic wrap debris, keeping the working environment clean, thus achieving the effect of improving packaging stability and maintaining the working environment.

[0026] Furthermore, sliders 13 are fixedly connected to both sides of the bottom of the support frame 12, and both sliders 13 are slidably connected to the bottom inner side of the frame 1 through the sliding groove 14. The sliding cooperation between the sliders 13 and the sliding groove 14 enables the support frame 12 to move smoothly and steadily within the frame 1, reducing frictional resistance, improving the operating efficiency of the equipment, and ensuring the positioning accuracy of the support frame 12, thereby improving the smoothness of equipment operation and the accuracy of positioning.

[0027] Furthermore, one end of the rotating rod 16 passes through the side wall of the frame 1 via a bearing sleeve, and the connection between the output shaft of the cylinder 11 and the side plate 8 is a sliding connection. The use of the bearing sleeve reduces wear and noise when the rotating rod 16 rotates, and improves the smoothness of rotation. The sliding connection between the output shaft of the cylinder 11 and the side plate 8 makes the cylinder 11 more flexible when pushing the bearing sleeve 9, adapting to the packaging needs of carrots of different sizes, and achieving the effect of enhancing the durability and flexibility of the equipment.

[0028] Furthermore, a threaded rod 5 is provided on one side of the top of the mounting sleeve 3, and threaded grooves 6 that cooperate with the threaded rod 5 are opened on one side of the mounting sleeve 3 and one end of the plastic wrap wrapping roller 4. The operator can rotate the threaded rod 5 to screw it into or out of the threaded groove 6, thereby easily realizing the detachable connection between the plastic wrap wrapping roller 4 and the mounting sleeve 3. This facilitates the replacement of plastic wrap wrapping rollers 4 of different specifications or types, improves the versatility and maintenance convenience of the equipment, and achieves the effect of simplifying the replacement process and improving the versatility of the equipment.

[0029] Furthermore, support rods 18 are fixedly connected to the opposite sides of the two arc-shaped clamping plates 17, and one end of each support rod 18 penetrates the side wall of the bearing sleeve 9. Tension springs 19 are fitted on the extended ends of the two support rods 18. One end of each support rod 18 is elastically connected to the outer wall of the bearing sleeve 9 through the tension springs 19. The elastic force of the tension springs 19 allows the arc-shaped clamping plates 17 to clamp the carrot tightly and evenly, maintaining a good clamping effect even when the size of the carrot changes. At the same time, the guiding effect of the support rods 18 ensures the accuracy of the clamping direction of the arc-shaped clamping plates 17, thereby improving the clamping stability and adaptability.

[0030] In summary:

[0031] The operator first inserts one end of the carrot to be wrapped with plastic wrap 20 into the connecting sleeve 7, ensuring the carrot end is slightly inserted for stable support. Next, the cylinder 11 is activated, its output shaft driving the bearing sleeve 9 and the elastically connected arc-shaped clamping plates 17 on both sides of the inner side towards the carrot via the connecting plate 10, until one end of the bearing sleeve 9 is tightly fitted onto the other end of the carrot. At this point, the arc-shaped clamping plates 17, under the elastic force of the tension spring 19, firmly hold the carrot, ensuring it does not wobble or fall off. Then, the operator manually drags the starting end of the plastic wrap 20 on the plastic wrap wrapping roller 4 and wraps it around the carrot once, while the deformable wrapping rope 21 embedded in the plastic wrap 20 enhances the stability of the initial wrapping. After preparation, the drive motor 15 is activated, which drives the bearing plate 2 to rotate via the rotating rod 16, thereby driving the mounting sleeve 3 and the plastic wrap wrapping roller 4 on it to move in a circular motion around the carrot, achieving automatic continuous wrapping of the plastic wrap. During this process, the carrier frame 12, which is slidably connected to the bottom inner side of the frame 1, provides an additional support platform for the carrot, ensuring stability and facilitating the collection of plastic wrap debris. As the carrier tray 2 continues to rotate, the plastic wrap 20 is evenly and tightly wrapped around the surface of the carrot. After wrapping, the cylinder 11 is activated again, causing the carrier sleeve 9, along with the arc-shaped clamp 17, to detach from the carrot, allowing the operator to easily remove the packaged carrot. The entire process is continuous and efficient, and can continuously complete the plastic wrap wrapping of multiple carrots. The cooperation between the connecting sleeve 7 and the bearing sleeve 9, along with the design of the arc-shaped clamping plate 17 and the tension spring 19, ensures stable clamping of carrots during the winding process, improving packaging accuracy and stability. The transmission structure of the drive motor 15, rotating rod 16, and bearing plate 2 enables automatic continuous winding of the cling film, greatly improving packaging efficiency. The use of bearing sleeves reduces wear and noise during rotation, improving the durability of the equipment. The sliding connection between the output shaft of cylinder 11 and the side plate 8 enhances the flexibility of the equipment, adapting to the packaging needs of carrots of different sizes. The design of the bearing frame 12, slider 13, and groove 14 not only provides additional support for the carrots but also facilitates cleaning and maintenance. The detachable connection design of the threaded rod 5 and threaded groove 6 simplifies the replacement process of the cling film winding roller 4, improving the versatility and maintenance convenience of the equipment.
