A transmission mechanism 4 for driving the transmission of the net sleeve conveying group is installed outside the conveying frame 2. The net sleeve conveying assembly 3 is driven to operate through the transmission mechanism 4, and the automatic conveyance of the net sleeve is realized through the net sleeve conveying assembly 3.

[0039] A net sleeve cutting mechanism 5 is installed on the frame 1 and at the bottom of the conveying frame 2. The net sleeve conveyed by the net sleeve conveying assembly 3 can be cut by the net sleeve cutting mechanism 5 to cut the net sleeve into a uniform length.

[0040] As Figure 2 and Figure 4 shown, the net sleeve conveying assembly 3 includes a plurality of core molds 301. The plurality of core molds 301 are arranged and installed inside the conveying frame 2. A first material conveying roller group 302 and a second material conveying roller group 303 are penetrated through the core molds 301. The first material conveying roller group 302 is located above the second material conveying roller group 303 and is arranged at an angle and staggered with the second material conveying roller group 303. The first material conveying roller group 302, the second material conveying roller group 303, and the core molds 301 jointly form a space for clamping and conveying the net sleeve. Specifically, the net sleeve is sleeved outside the core molds 301 and is between the core molds 301 and the first material conveying roller group 302 and the second material conveying roller group 303. In this embodiment, the first material conveying roller group 302 and the second material conveying roller group 303 are arranged at 90°, so that the net sleeve can be clamped and conveyed in four directions around the circumference at the same time.

[0041] One end of the first material conveying roller group 302 and the second material conveying roller group 303 is rotatably installed on the conveying frame 2, and the other end penetrates through the side wall of the conveying frame 2 and is in transmission connection with the transmission mechanism 4. In this embodiment, there are four core molds 301, one group of the first material conveying roller group 302, and the first material conveying roller group 302 sequentially passes through the four core molds 301. There are four groups of the second material conveying roller group 303, and each group of the second material conveying roller group 303 respectively passes through one core mold 301. At the same time, one end of one group of the first material conveying roller group 302 and four groups of the second material conveying roller group 303 penetrates through the side wall of the conveying frame 2 and is in transmission connection with the transmission mechanism 4. The transmission mechanism 4 drives one group of the first material conveying roller group 302 and four groups of the second material conveying roller group 303 to rotate synchronously. The first material conveying roller group 302 and the second material conveying roller group 303 act together with the core mold 301 to realize the clamping and conveying of the mesh sleeve.

[0042] As Figure 4 shown, the core mold 301 is provided with a first arc-shaped groove 3011 corresponding to the first material conveying roller group 302 and a second arc-shaped groove 3012 corresponding to the second material conveying roller group 303. The first arc-shaped groove 3011 is arranged corresponding to the first material conveying roller group 302 and is adapted to it. The mesh sleeve is sleeved between the first arc-shaped groove 3011 and the first material conveying roller group 302. The second arc-shaped groove 3012 is arranged corresponding to the second material conveying roller group 303 and is adapted to it. The mesh sleeve is simultaneously sleeved between the second arc-shaped groove 3012 and the second material conveying roller group 303.

[0043] One end of the core mold 301 close to the mesh sleeve expanding mechanism 6 is provided with a mesh sleeve expanding part 3013, and the diameter dimension of the mesh sleeve expanding part 3013 is larger than the diameter dimension of the core mold 301. The mesh sleeve can be pre-expanded by a certain size through the mesh sleeve expanding part 3013, which is convenient for the insertion of the mesh sleeve expanding mechanism 6. One end of the core mold 301 far from the mesh sleeve expanding mechanism 6 is provided with a guiding part 3014, and the diameter dimension of the guiding part 3014 is smaller than the diameter dimension of the core mold 301. By setting the guiding part 3014, it is convenient to sleeved the mesh sleeve on the core mold 301.

[0044] As Figure 2 shown, the roller bodies of the first material conveying roller group 302 and the second material conveying roller group 303 are both provided with threads for increasing the friction force with the mesh sleeve. By setting the threads, the friction force between the first material conveying roller group 302 and the second material conveying roller group 303 and the mesh sleeve is increased, making the conveying of the mesh sleeve smoother.

[0045] As Figures 1-3As shown, the transmission mechanism 4 includes a reduction motor 401 installed on the frame 1, the reduction motor 401 is provided with a first output shaft 402 and a second output shaft 403, the first output shaft 402 is provided with a first driving wheel 404, the first feed roller group 302 is provided with a first driven wheel 405 corresponding to the first driving wheel 404, the first driving wheel 404 and the first driven wheel 405 are connected by a first transmission belt 406, thereby, the first driving wheel 404 drives the first driven wheel 405 to rotate synchronously through the first transmission belt 406, and the first driven wheel 405 drives the first feed roller group 302 to rotate synchronously;

[0046] A second driving wheel 407 is mounted on the second output shaft 403, and a second driven wheel 408 corresponding to the second driving wheel 407 is disposed on the second feed roller group 303. The second driving wheel 407 and the second driven wheel 408 are connected to each other through a second transmission belt 409, whereby the second driving wheel 407 drives the second driven wheel 408 to rotate through the second transmission belt 409, and the second driven wheel 408 drives the second feed roller group 303 to rotate synchronously, so that the first feed roller group 302 and the second feed roller group 303 synchronously convey the mesh sleeve;

[0047] In addition, guide wheels 410 are disposed between the first driving wheel 404 and the first driven wheel 405 and between the second driving wheel 407 and the second driven wheel 408 , and the first transmission belt 406 and the second transmission belt 409 are both wound around the guide wheels 410 .

[0048] like Figures 1-2 As shown, a first guide roller group 7 and a second guide roller group 8 are also installed on the top of the conveying frame 2. The first guide roller group 7 is located above the second guide roller group 8 and is staggered with the second guide roller group 8 at an angle. The first guide roller group 7 and the second guide roller group 8 are both rotatably installed on the conveying frame 2. In this embodiment, the first guide roller group 7 and the second guide roller group 8 are set at 90°, thereby achieving comprehensive guiding and limiting of the mesh sleeve in the horizontal direction. Since the first guide roller group 7 and the second guide roller group 8 are both rotatably installed on the conveying frame 2, the mesh sleeve is transported more smoothly. When in use, the mesh sleeve passes through the first guide roller group 7 and the second guide roller group 8 in turn, and is sleeved on the core 301, and is transported downward under the drive of the first feed roller group 302 and the second feed roller group 303.

[0049] like Figures 2-3 and Figure 5As shown in the figure, the net sleeve cutting mechanism 5 includes a movable rod 501 slidably mounted on the frame 1. Specifically, the movable rod 501 is slidably mounted on a guide block, and the guide block is mounted on the frame 1. Insulating and heat-insulating blocks 502 are mounted on the movable rod 501. An electric heating wire 503 for thermally cutting the net sleeve is provided between the insulating and heat-insulating blocks 502 and near the net sleeve conveying assembly 3. Both ends of the electric heating wire 503 are connected with conductive joints 504, and the conductive joints 504 are connected to an external control circuit;

[0050] One end of each of the two movable rods 501 is connected with a connecting rod 505. A first pushing device 506 is provided between the connecting rod 505 and the frame 1. In this embodiment, the first pushing device 506 can be a cylinder. The first pushing device 506 is mounted on the frame 1, and the piston rod of the first pushing device 506 is connected with the connecting rod 505. When the external control circuit is switched on, the electric heating wire 503 generates heat, and under the push of the first pushing device 506, thermal cutting of the net sleeve is realized.

[0051] As Figures 2-3 and Figures 5-6 shown in the figure, the net sleeve spreading mechanism 6 includes a moving frame 601. The moving frame 601 is movably mounted on the frame 1 through a lifting assembly 602. The moving frame 601 can move up and down on the frame 1 through the lifting assembly 602. Oppositely arranged support rods 603 are movably mounted on the moving frame 601. A number of oppositely arranged spreading pieces 604 are arranged on the two support rods 603. The spreading pieces 604 are arranged corresponding to the net sleeve conveying assembly 3. The net sleeve conveyed by the net sleeve conveying assembly 3 can be spread by the oppositely arranged spreading pieces 604. Cooperating with the lifting assembly 602 to drive the moving frame 601 to move up and down, the net sleeve can be sleeved on the fruits conveyed on the fruit conveying line, realizing the functions of automatically spreading the net sleeve and sleeving the net.

[0052] As Figures 2-3 and Figures 5-6 shown in the figure, both ends of the two support rods 603 are respectively slidably mounted on the moving frame 601 through sliding assemblies 605. First lead screw nuts 606 are also respectively mounted on the two support rods 603. First lead screws 607 with opposite thread directions are respectively inserted into the first lead screw nuts 606. Both ends of the first lead screw 607 are respectively rotatably mounted on the moving frame 601, and one end extends to the outside of the moving frame 601 and is connected with a synchronous motor 608. By driving the first lead screw 607 to rotate through the synchronous motor 608, since the thread directions on the first lead screw 607 are opposite, the two support rods 603 move towards or away from each other along the moving frame 601, and then drive the spreading pieces 604 to approach or move away from each other, facilitating the insertion of the net sleeve spreading mechanism 6 into the net sleeve and spreading the net sleeve;

[0053] In this embodiment, the sliding component 605 includes a slider and a guide rail. The slider is installed at the end of the support rod 603, the guide rail is installed on the moving frame 601, and the slider is slidably installed on the guide rail, thereby realizing the movement guidance of the support rod 603.

[0054] As Figures 2-3 and Figures 5-6 shown, the lifting component 602 includes connection blocks 6021 oppositely installed on the moving frame 601. A second lead screw 6022 is threadedly penetrated through the connection blocks 6021. One end of the second lead screw 6022 is rotatably installed at the top of the machine frame 1, and the other end is rotatably installed at the bottom of the machine frame 1. One end of the second lead screw 6022 penetrates through the machine frame 1 and is connected to a driving motor 6023;

[0055] A guide rod 6024 is also slidably penetrated through the connection blocks 6021. Both ends of the guide rod 6024 are installed at the top and bottom of the machine frame 1 respectively. By driving the driving motor 6023, the second lead screw 6022 can be driven to rotate. During the rotation of the second lead screw 6022, the connection blocks 6021 are driven to move axially along the guide rod 6024, thereby driving the moving frame 601 to move synchronously, and thus realizing the lifting movement of the mesh sleeve expanding mechanism 6.

[0056] For easy understanding, the working process of this embodiment is given below:

[0057] As Figures 1-6As shown, the fruit conveyor line conveys the fruit to the bottom of the frame 1, and then the reduction motor 401 of the transmission mechanism 4 runs, and the reduction motor 401 drives the first feed roller group 302 and the second feed roller group 303 to move synchronously through the first transmission belt 406 and the second transmission belt 409, and the first feed roller group 302 and the second feed roller group 303 work together with the core 301 to transport the mesh pre-mounted on the core 301 downward for a certain distance. Since the end of the core 301 close to the mesh opening mechanism 6 is provided with a mesh opening part 3013, the mesh can be pre-opened to a certain size through the mesh opening part 3013, so that the opening piece 604 of the mesh opening part 3013 can be inserted into the mesh, and then the first pushing device 506 extends, and pushes the movable rod 501 to move synchronously through the connecting rod 505, and the electric heating wire 503 installed on the movable rod 501 is energized to perform thermal cutting on the mesh. After the cutting is completed, the first pushing device 50 6 contracts to restore the electric heating wire 503 to its initial position. At the same time, the synchronous motor 608 of the net sleeve opening mechanism 6 runs synchronously. The synchronous motor 608 drives the two opening pieces 604 to move in the opposite direction through the first screw 607. The two opening pieces 604 completely open the net sleeve. After that, the driving motor 6023 of the lifting component 602 runs to drive the net sleeve opening mechanism 6 to move downward through the second screw 6022. After that, the synchronous motor 608 runs in the opposite direction to make the two opening pieces 604 move toward each other so that the opened net sleeve is sleeved on the fruit conveyed on the fruit conveying line. After that, the net sleeve opening mechanism 6 continues to move downward and makes the opening pieces 604 detach from the net sleeve. After that, the driving motor 6023 of the lifting component 602 runs in the opposite direction to drive the net sleeve opening mechanism 6 to return to its initial position. The fruit conveying line is intermittently conveyed to convey the netted fruit to the next process. After that, the above-mentioned actions are repeated to perform the netting action on the fruit conveyed again by the fruit conveying line.

[0058] In summary, the utility model provides a net conveying and net supporting device, which integrates net conveying, cutting and net supporting, realizes automatic net packaging of fruits, has high efficiency, and reduces labor costs and workload.
