Abstract

The invention relates to a bagging device used for bagging fruits with mesh bags. The bagging device comprises a clamping separating assembly, a bag supporting assembly, a lifting mechanism and a rack, the lifting mechanism and the clamping separating assembly are installed on the rack, the bag supporting assembly is arranged above the clamping separating assembly and is installed on the lifting mechanism, and the lifting mechanism can drive the bag supporting assembly to move up and down; and the bag supporting assembly comprises a bag supporting mechanism and a bag supporting driving mechanism, the bag supporting mechanism comprises bag supporting claws capable of opening and closing in parallel, the clamping separating assembly comprises a clamping separating mechanism, the clamping separating mechanism comprises clamping separating claws, the bag supporting claws and the clamping separating claws are evenly distributed along a circle, and the clamping separating claws and the bag supporting claws are staggered in the circumferential direction. The overall structure is simple, and the bagging efficiency is high; and stress is even during supporting or clamping separation of a net bag, and the net bag can be prevented from being damaged by supporting or clamping.

Description

technical field [0001] The invention relates to a bagging device, in particular to a bagging device for covering fruit with a net bag, and belongs to the field of fruit packaging machinery. Background technique [0002] In order to prevent the fruit from bumping during transportation, the fruit is protected by a foam net bag. The traditional fruit net bag packaging (such as apples, pears, pomegranates, etc.) is mostly packaged manually, and the packaging efficiency is extremely low. The fruit mesh bag has a mesh structure, has a certain degree of elasticity, is made of air bubbles, and has a certain friction force on the surface, and when the friction is too large, the air bubbles will be damaged, and even the mesh bag will be broken. [0003] In the prior art, fruit net bag packaging machines are continuously released, but these machines are generally complex in structure, or cannot be automated, and still need manual bag support. [0004] Now we have developed a fruit net...

Problems solved by technology

[0003] In the prior art, fruit net bag packaging machines are continuously introduced, but these machines generally have complex structures, or cannot be automated, and still need manual bag support

[0004] Now we have developed a fruit net bag support mechanism, which requires the manipulator to open the net bag and put it on the fruit. When the manipulator withdraws, the net bag needs to be left on the fruit, but when the manipulator withdraws, the net bag will easily follow the manipulator. To tear the fruit net bag, a mechanism is needed to remove the net bag, that is, the fruit net bag clipping mechanism, which is a very important part of the packaging line. The manipulator will open the net bag and cover the fruit with the net bag. Then the pinch-off mechanism is needed to clamp the mesh bag to prevent the mesh bag from leaving the fruit with the manipulator, resulting in packaging failure; if the pinch-off mechanism is too loose, it will not achieve the effect of clamping; if it is too tight, it will easily cause the fruit mesh bag to break; The fruit is placed on the pinching mechanism, and the bumping of the fruit should also be prevented

[0005] It is easy to think of the manipulator that opens the mesh bag as an umbrella structure. Since the claws that make up the umbrella structure are straight rods and are composed of one end hinged, it leads to a cone shape when stretched, although it is convenient to put the mesh bag on. However, because the movement process is oscillating, and the shrinkage state is conical, there is still the problem that the mesh bag is not easy to fit on the fruit, and the mesh bag is easy to slip forward due to the forward partial thrust during the stretching process. Once the stretching device is stretched into an inverted conical shape, the net bag will be difficult to disengage from the manipulator; in addition, the larger the contact area between the claws of the manipulator and the net bag, the greater the friction force on the net bag and the easier it is to be damaged
