Automatic fruit packaging machine

Abstract

The invention discloses an automatic fruit packaging machine, which comprises a frame. The frame is provided with a storage mechanism, a feeding mechanism, a cutting mechanism and a fruit dischargingmechanism. The feeding mechanism transfers a net bag stored by the storage mechanism to a packaging position. The net bag is opened at the packaging position. The fruit discharging mechanism transfersfruit to the packaging position and puts the fruit into the net bag. The cutting mechanism cuts off the net bag and fruit packaging is completed. The storage mechanism comprises a foam net bag tray and an air expansion support shaft which is coaxially fixed to the foam net bag tray. The air expansion support shaft provides driving force through a worm gear reducer. A discharge port of the foam net bag tray is sequentially provided with a tension shaft assembly and a guide shaft assembly from top to bottom. The automatic fruit packaging machine can realize automatic operation of fruit net bagpackaging, improve packaging efficiency, and reduce human resource costs, and has a wide range of application prospects in the field of fruit packaging.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to an automatic fruit packaging machine, in particular to an automatic fruit packaging machine packed with foam net bags. Background technique [0002] The foam mesh bag refers to the mesh bag that is cut into segments using polyethylene extruded foam mesh and then fitted around the fruit to protect the transportation safety of the fruit and improve the appearance of the fruit. Existing netting operations on fruits mostly rely on manual work. Because the surface of the fruit is crisp and tender, it is difficult to control the strength during the manual netting process, which may easily cause the surface of the fruit to be damaged by external forces. At the same time, in the peak season of fruit ripening, the manual netting operation will bring greater labor intensity, increase labor costs, and relatively low efficiency, resulting in an increase in fruit production costs and even...

Problems solved by technology

[0003] Chinese patent (Application No. 201721914810.3) discloses a foam hot-cut sealing and cutting packaging machine for fruit packaging. The refueling and packaging efficiency of this device are too low; the foam net of the device clamps the top opening of the foam net through the chuck, and It is fixed in the middle of the lifting seat, and the center of the lifting seat is provided with a fruit-throwing hole, in which the fruit-throwing hole corresponds to the opening position of the upper end of the foam net bag

Although this packaging machine has solved the problem of low processing efficiency due to the inconvenience of disassembly and refueling caused by continuous packaging, it still has shortcomings: when the single-layer film is bent into a cylindrical film, there is a large Inconvenience and uncertainty. At the same time, there may be multiple plastic seals during the plastic sealing of the side opening, resulting in the problem that the plastic seal of the side opening cannot be effectively sealed or leaked; at the same time, there is no buffer device in the entire path of the fruit packaging, which will cause the fruit from After falling in the air, it penetrates the sealed film bag and causes some damage to the fruit
