[0002] Net bags are a common packaging material and are widely used in the packaging and transportation of various items. Items packaged in net bags include but are not limited to fruits (such as oranges, tangerines), vegetables, seeds, small items, etc. Net bags can provide certain protection for the items inside to prevent damage during transportation. The mesh structure allows air circulation, which helps to maintain the freshness of fruits and vegetables. Net bags are usually equipped with handles or ropes for easy carrying, making transportation more convenient. Many net bag materials are durable and reusable, which helps reduce the waste of packaging materials. Compared with traditional packaging materials, net bags are less expensive and can save packaging costs.

[0021] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] See also Figures 1 to 7 The embodiment of the utility model discloses a bundling and labeling device for net bag packaging, which mainly includes a frame 1, a blanking device 2, a labeling machine 3, a guide roller group 302, a power device, a power knife and a binding device. The frame 1 is fixedly arranged and adopts a frame structure, which can withstand various forces and vibrations generated during the packaging process. The blanking device 2 is located at the top of the frame 1 and is used to put pre-prepared materials (such as fruits, vegetables, etc.) into the net bag. The design of the blanking device 2 ensures that the materials can fall into the net bag accurately and quickly, preparing for the subsequent packaging process.

[0023] A marking machine 3 is installed on the frame 1 for conveying and printing label paper. A label tray 301 is provided on the upper part of the marking machine 3 for storing the label paper to be printed. A guide roller group 302 is provided below the label tray 301. The guide roller group 302 includes a power roller and a clamping roller. The two work together to ensure that the label paper can be conveyed smoothly and continuously. The power device provides power to the guide roller group 302. The conveying motor is used as the power source. By controlling the speed and direction of the motor, the conveying speed of the label paper can be accurately adjusted, which is convenient for accurate labeling each time. The power knife is arranged below the guide roller group 302 and is used to cut the label paper. The power knife includes a cutting cylinder 303 and a blade. The blade is slidably arranged inside the guide block 304. The front end of the guide block 304 is provided with a through slot for guiding the label paper to pass through. When the label paper reaches the specified position, the cutting cylinder 303 drives the blade to move quickly to cut the label paper. After cutting, the blade resets and the guide roller group 302 transports the next label paper to the specified position inside the specified auxiliary. When the seal is squeezed, the bottom of the label paper is pressed between the seal and the net bag to achieve the labeling effect.

[0024] The binding device is arranged below the marking machine 3, and is used to bundle and seal the net bag containing the material. The binding device includes a pushing rack 101, a V-shaped plate and a sealer. The pushing rack 101 is used to push the net bag to the V-shaped plate. The design of the V-shaped plate allows the net bag to gradually shrink and fix its shape. The sealer is located at the bottom of the V-shaped plate and is used to wrap the seal around the opening of the net bag and fix it. The sealer includes a fixing block, a chute, a material tray 4, a conveying wheel 404, an extrusion head 402 and a sealing device. And driving motor 401, the fixed block is installed on the frame 1, and a slide groove is provided on its side. The material tray 4 is used to store the seal. The seal extends into the slide groove through the conveying wheel 404. The seal is provided with two simultaneous conveyings. The extrusion head 402 is slidably set inside the slide groove, and its tail is connected to the driving motor 401. When the seal reaches the specified position, the driving motor 401 drives the extrusion head 402 to move forward, and the seal is tightly wrapped around the net bag. The end of the extrusion head 402 is provided with a push block 4021 and The cutting knife 4021 is provided with two forming grooves 4022 on the pushing block 4021, and the auxiliary block 403 is provided on the opposite side of the forming groove 4022. The auxiliary block 403 is provided with an auxiliary groove, and two auxiliary grooves are arranged opposite to the forming groove 4022. The pushing block 4021 moves to cut the seal that penetrates into the inside of the slide groove. At the same time, the forming groove 4022 prevents the seal from falling. The pushing block 4021 continues to move in the direction of the auxiliary block 403. After the pushing block 4021 and the auxiliary block 403 are buckled, the seal is wrapped around the outer side of the net bag and deformed and tightened to ensure that the seal can be firmly fixed on the net bag. During the movement of the pushing block 4021, the upper seal tightens the bottom of the label paper on the net bag. At the same time, the cutter is used to cut the net bag between the two seals, completing the sealing process, so that the lower seal serves as the seal of the upper part of the lower net bag, and the upper seal and label paper serve as the bottom of the next net bag for sealing. The working process is continuous and fast, which greatly improves the efficiency of sealing and labeling the net bag and ensures the use effect.

[0025] In actual operation, the material is first loaded into the net bag through the blanking device 2, the marking machine 3 prints the label paper according to the preset label information, and the label paper is cut and transported to the inside of the binding device through the guide roller group 302 and the power knife. Then, the pushing rack 101 in the binding device pushes the net bag to the V-shaped plate for shrinkage and fixing the shape, the sealer wraps the seal around the opening of the net bag and fixes it, and the cutter cuts the excess net bag material to complete the entire packaging process. It has the advantages of high degree of automation, high packaging efficiency and good continuity, and can significantly improve the production efficiency and product quality of net bag packaging.
