Description
Technical Field
The invention relates to the technical field of fruit packaging, in particular to a fruit net cover opening component and fruit packaging equipment.
Background
In recent years, with the improvement of the living standard of people, the demand and the yield of fruits are increased, however, in the transportation process of the fruits, the conditions of collision, extrusion and the like can occur, and the fruits are damaged.
At present, in order to reduce damage to fruits caused by collision, extrusion and other conditions in the transportation process, the fruits are usually packaged in a bagging mode, and specifically, a foaming net is usually sleeved on the surface of the fruits to protect the foaming net, so that the damage rate of the fruits is reduced.
When fruit is packed, two packing modes, namely manual bagging and machine bagging, are generally included. The manual bagging method is characterized in that a foaming net is manually expanded, fruits are stuffed into the foaming net or the foaming net is sleeved on the fruits, so that the fruits are wrapped by the foaming net, however, the manual bagging method is low in efficiency and high in labor cost, and is difficult to be suitable for bagging large-scale fruits;
meanwhile, the machine bagging is used for automatically bagging, the automation degree is high, the labor cost can be greatly reduced, and the fruit packaging efficiency can be improved.
However, although the use of machine bagging can greatly improve the packaging efficiency, the inventor finds that, in the process of bagging by using a machine at present, the defects exist, in particular:
the packaging machine used at present usually struts one end or two ends of a foaming net when the foaming net is expanded, and the expanded degree of the end part of the foaming net is usually larger than or equal to the maximum cross-sectional area of the fruit, so that the fruit enters the foaming net through the end part of the foaming net, for example, in the chinese patent with the application number CN 202250111561.3, a net sleeve expanding claw pushes a net sleeve pressing block to move in the same direction while expanding a fruit net sleeve; after the fruit is positioned, the upper end of the fruit net sleeve is opened to form a proper opening and is acted by a second compression spring, the second compression spring presses the net sleeve guide plate and the fruit net sleeve to the vertical part of the net sleeve opening hook, at the moment, the lifting mechanism moves downwards to reset, the lock tongue group and the buckle are locked, the net sleeve opening hook keeps an outward extrusion opening state, and fruit dropping is conveniently carried out at a fruit dropping station in the later stage; and in the Chinese patent with the application number CN201611125016.0, when the conical barrel is jacked up, the nylon idler wheel and the conical barrel jointly act to transport the continuous net sleeve sleeved on the conical barrel down to be sleeved on the four supporting rods, when the length of the net sleeve reaches the length required by wrapping fruits, the four supporting rods are lowered through the rotation of the first cam, and then the net sleeve falls and is sleeved on the fruits on the conveying belt.
The net sleeves in the two patents are opened in a manner that one end or two ends of the net sleeve are opened to a greater degree before bagging so that fruits can be put into the foaming net. However, the currently used foam net is usually made of polyethylene material, and in the process of expanding the foam net, the speeds of the foam net recovering deformation when the foam net is expanded for a long time and the foam net is expanded for a short time are different, wherein the speed of the foam net recovering deformation when the foam net is expanded for a long time is slower; before the fruits fall into the foaming net, the opening degree of one end of the foaming net is close to that of the middle of the foaming net, and the foaming net is opened in advance so that the fruits fall into the foaming net, so that one end of the foaming net and the middle of the foaming net are in an opened state for a long time, the difference between the cross sections of the opened end of the foaming net and the middle of the foaming net is reduced, in a short time after the fruits are bagged, a certain time is required for the foaming net to recover and deform, so that the fruits are easy to move towards the opened end of the foaming net and even to be separated from the opened end of the foaming net, particularly, when the fruits are transported in a short time after being bagged, the difference between the opened end of the foaming net and the cross section of the middle of the foaming net is still small, and when the foaming net on the fruits is driven to move by the movement of adjacent fruits, the foaming net is easier to be separated from the fruits, and therefore the fruit protection of the foaming net is not facilitated.
