Description

Technical Field

[0001] The invention relates to an automatic fruit flexible mesh sleeve packaging device and a suspension core device, belonging to the technical field of fruit packaging equipment. Background Art

[0002] In fruit packaging, such as apples, pears and other similar shaped fruits, nets are often used. The nets are placed on the outside of the fruits to protect the fruits from being damaged by bumps during transportation. Especially for fruits such as apples, which have stalks, they are more likely to be damaged by bumps during transportation. At present, manual packaging is mainly used for net packaging, which has a large workload and low efficiency. Therefore, those skilled in the art are studying a device for realizing automatic packaging of fruit nets. Summary of the invention

[0003] Aiming at the problem of low automation of net sleeve packaging in the existing fruit packaging process, a fruit flexible mesh net sleeve automatic packaging equipment and a suspension core device are provided.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] A fruit flexible mesh net automatic packaging equipment, comprising a frame, a front fruit conveying transmission belt group installed on the frame, a fruit net packaging mechanism and a rear fruit packing group, characterized in that the fruit net packaging mechanism comprises a fruit straightening group and a net set group; the net set group comprises a net drum installed on the top of the frame, a suspension core assembly is installed below the net drum, a roller group is installed below the suspension core assembly, and an electric heating wire cutting device is installed below the roller group; the suspension core assembly comprises a conical suspension core body and an outer annular magnet sleeved outside the suspension core body, a flared skirt body is provided at the bottom of the suspension core body, the suspension core body is provided with an inlay cavity, and the annular magnet is inlaid in the inlay cavity; the roller group comprises a pair of rollers, the rollers are installed on the frame through roller shafts and bearing seats at both ends of the roller shafts, each of the two roller shafts has a gear, the two gears are meshed, and a motor B is installed at the end of one of the roller shafts; the rollers are located on both sides of the lower skirt of the suspension core body.

[0006] The net used in the present invention is a flexible shockproof net for fruits and vegetables, also known as pearl cotton net, foam net, EPE foam net, which has elastic properties and can be stretched and expanded externally within a certain elastic limit on the original basis. When expanding externally, the net will shrink due to its elastic properties. It is processed with new high-quality EPE pearl cotton materials, which is environmentally friendly and odorless, and the materials are safe and stable, and will not affect the quality of fruits and vegetables.

[0007] This kind of mesh has a mesh structure (Fig.15 ), the foaming rate is divided into two specifications of 1:40 and 1:50, respectively, two elastic limits of external expansion. The present invention adopts a mesh flexible foam net with a foaming rate of 1:40, which is used to prevent fruits, vegetables and other fragile items from being damaged due to collision during transportation, and plays a protective role. At the same time, it makes fruits and vegetables easier to transport and preserve, and more beautiful.

[0008] In the simulation force analysis diagram ( Fig.16 ), the motor exerts a downward force of 10N on the mesh, which can provide sufficient power for the mesh to change from a flat state to a circular state outside the suspended core.

[0009] The beneficial effects of the above technical solution are as follows: the above technical solution is aimed at the unsheared rolled net sleeve, and utilizes the principle of mutual repulsion between the two annular magnets (annular magnet and outer annular magnet) in the suspension core assembly. The annular magnet is placed in the suspension core body, and the suspension core body passes through the inner ring of the outer annular magnet, so that the repulsive force acts indirectly on the suspension core body, and the suspension effect of the suspension core body is achieved. The continuous rolled net sleeve is supported by the suspension core after passing through the suspension core, and the continuous transmission and cutting of the net sleeve are achieved through the roller group and the electric heating wire cutting device. The present invention solves the problems of low efficiency of the net sleeve processing steps and unsightly packaging in the process of netting apples, and innovatively applies the magnetic levitation principle to the assembly of fruit net sleeves.
