[0006] Furthermore, the first clamping claw mechanism includes a clamping claw cylinder and two arc-shaped clamping claws, the clamping claws are installed on the working end of the clamping claw cylinder, the clamping claw cylinder drives the change of the relative distance between the two clamping claws to clamp and loosen the mesh sleeve, the clamping claw cylinder is installed on the frame through a bolt assembly, and the clamping claws are matched with the bottom of the mesh sleeve support after closing.

[0007] Furthermore, the first clamping claw mechanism and the second clamping claw mechanism have the same structure.

[0008] Furthermore, the cutting knife mechanism includes a cutting knife cylinder and a cutting knife, the cutting knife is installed on the working end of the cutting knife cylinder, and the claw cylinder drives the cutting knife to extend and retract to cut the mesh sleeve.

[0024] Figure 1 As shown, an uninterrupted pear netting device comprises a frame 1, a mobile frame 2, a net support 3, a net conveying mechanism 4, a placing plate 5, a lifting mechanism 6, a first claw mechanism 7, a cutting knife mechanism 8, a second claw mechanism 9 and a net 10. The mobile frame 2 is slidably connected to the vertical sliding rod of the frame 1, and at least one set of lifting mechanisms 6 is installed between the mobile frame 2 and the frame 1. The mobile frame 2 is arranged as a square frame, and the net support 3 is installed in the middle position of the square frame. The net conveying mechanism 4 is symmetrically installed on both sides of the net support 3. The gap between the net support 3 and the net conveying mechanism 4 is adapted to the thickness of the net 10. The placing plate 5 is installed at the cross center of the frame 1 and is located directly below the mobile frame 2. The upper and lower ends of the pears to be packaged on the placing plate 5 correspond to the first claw mechanism 7 and the second claw mechanism 9 respectively. The first claw mechanism 7 and the second claw mechanism 9 are installed on the frame 1, and the cutting knife mechanism 8 is installed on the frame 1 and is located below the first claw mechanism 7.

[0025] Specifically, refer to Figure 2 and Figure 4The first clamping jaw mechanism 7 includes a clamping jaw cylinder 701 and two arc-shaped clamping jaws 702. The clamping jaws 702 are installed on the working end of the clamping jaw cylinder 701. The clamping jaw cylinder 701 drives the relative distance between the two clamping jaws 702 to clamp and loosen the mesh sleeve 10. The clamping jaw cylinder 701 is installed on the frame 1 through a bolt assembly. After the clamping jaws 702 are closed, they match the bottom of the mesh sleeve support 3. The first clamping jaw mechanism 7 has the same structure as the second clamping jaw mechanism 9.

[0026] This embodiment can clamp the net 10 to facilitate the subsequent cutting operation of the cutting knife 802, while ensuring that the size of the net is consistent and can completely cover the outer surface of the pear while avoiding damage to the outer surface of the pear.

[0027] Specifically, refer to Figure 2 and Figure 5 The cutter mechanism 8 includes a cutter cylinder 801 and a cutter 802. The cutter 802 is installed on the working end of the cutter cylinder 801 by bolts. The claw cylinder 701 drives the cutter 802 to extend to cut the mesh 10. The first claw mechanism 7 is set 18cm-20cm above the storage plate 5, and the cutter mechanism 8 is located 20mm below the first claw mechanism 7.

[0028] The positions of the cutting knife mechanism 8 and the first clamping claw mechanism 7 of this embodiment are arranged reasonably, and no interference will occur during the net-wrapping operation.

[0029] Specifically, refer to Figure 3 The mesh support 3 includes a mesh support body 301 and a mesh expansion body 302. The mesh support body 301 is a spherical structure. The bottom end of the mesh support body 301 is connected to the mesh expansion body 302 through a smooth curved surface. The mesh expansion body 302 is a flexible barrel structure. The mesh expansion body 301 and the smooth curved surface are integrally formed, and the mesh support body 301 is buckled on the smooth curved surface.

[0030] In this embodiment, a hole is provided at the bottom end of the supporting net body 301, and the expanded net body 302 is inserted into the hole and adhered to the supporting net body 301 to form a smooth transition. When in use, the bottom of the net sleeve 10 is sleeved on the net sleeve support 3, and the net sleeve 10 is stretched open by the supporting net body 301 of the net sleeve support 3. The expanded net body 302 makes the net sleeve 10 in a taut state, which is conducive to cutting the net sleeve 10. At the same time, the cut net sleeve 10 will be tightly held on the surface of the pear due to retraction.

[0031] Specifically, refer to Figure 1The net sleeve conveying mechanism 4 includes a roller 401, a coupling 402 and a motor 403. The motor 403 is installed on the mobile frame 2. One end of the roller 401 is connected to the motor 403 through the coupling 402, and the other end of the roller 401 is rotatably installed on the mobile frame 2. The roller 401 is cylindrical with a concave middle, and the concave part of the roller 401 is consistent with the outer wall of the supporting net body 301. When packaging, the net sleeve 10 is clamped between the roller 401 and the supporting net body 301 and moves downward with the rotation of the roller 401. Thereby, the contact area between the roller 401 and the net sleeve 10 can be increased, so that the pressure between the roller 401 and the net sleeve 10 is reduced, and the net sleeve 10 is prevented from being damaged due to the movement of the two.

[0032] In this embodiment, the mesh sleeve conveying mechanism 4 drives the two rollers 401 to rotate in opposite directions, so that the mesh sleeve 10 passes through the gap between the mesh sleeve support 3 and the mesh sleeve conveying mechanism 4, ensuring that the mesh sleeve 10 moves downward under the clamping action of the mesh sleeve support 3 and the rollers 401 to ensure uninterrupted input of the mesh sleeve 10.

[0033] Specifically, refer to Figure 1 The lifting mechanism 6 includes a lifting motor, a screw rod 601 and a slider 602. The lifting motor and the screw rod 601 are installed on the slide bar on one side of the frame 1. The slider 602 is threadedly connected to the screw rod 601. The slider 602 is connected to the moving frame 2. When the lifting motor is started, the screw rod 601 is driven to rotate, thereby driving the slider 602 and the moving frame 2 to move up and down.

[0034] The lifting mechanism 6 in this embodiment can be replaced by a hydraulic cylinder, an electric telescopic rod or other device that can achieve a telescopic effect.

[0035] The action process of the present invention is as follows:

[0036] First, the worker places the pears on the storage plate 5, and the movable frame is located about 20 mm above the pears. The bottom of the net sleeve 10 is mounted on the net sleeve support 3. The net sleeve 10 is opened by the supporting net body 301 of the net sleeve support 3, and the net sleeve conveying mechanism 4 is driven. The net sleeve 10 passes through the gap between the net sleeve support 3 and the net sleeve conveying mechanism 4, and moves downward under the support of the net sleeve conveying mechanism 4 until it passes through the bottom 10 mm of the expanded net body 302 of the net sleeve support 3, thereby realizing uninterrupted conveyance of the net sleeve 10.

[0037] At this time, the arc-shaped claws of the first claw mechanism 7 and the second claw mechanism 9 are both in the open state, and the movable frame 2 is driven downward by the lifting mechanism 6, so that the mesh support 3, the mesh conveying mechanism 4 and the mesh 10 are moved down 180 mm as a whole, ensuring that the bottom of the mesh 10 moves to the bottom of the storage plate 5 uninterruptedly, the claws of the second claw mechanism 9 are closed, and the mesh 10 is tightly clamped to the bottom of the storage plate 5, and the claws of the first claw mechanism 7 are closed, and the mesh 10 is tightly clamped to the bottom of the mesh support 3.

[0038] At the same time, the lifting mechanism 6 is driven to move up 180 mm. During this process, it is necessary to ensure that the linear speed of the net sleeve conveying mechanism 4 conveying the net sleeve 10 downward is the same as the linear speed of the lifting mechanism 6 driving upward to ensure that the net sleeve 10 does not move uninterruptedly.

[0039] Drive the cutter mechanism 8, the working end of the cutter cylinder 801 extends and drives the cutter 802 to cut the net sleeve 10. The first claw mechanism 7 and the second claw mechanism 9 are opened at the same time, and the cut net sleeve 10 is tightly held on the pear due to elasticity, and the net is completed, and the pears covered with the net sleeve 10 are taken out.

[0040] At this point, the device returns to the ready state, ready for the next pear netting job.

[0041] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
