Description

A fruit net cover expansion component and fruit packaging equipment

technical field

The invention relates to the technical field of fruit packaging, in particular to a fruit net cover expansion component and fruit packaging equipment.

Background technique

In recent years, with the improvement of people's living standards, the demand and output of fruits are increasing. However, during the transportation of fruits, there will be collisions and extrusions, which will cause damage to the fruits.

At present, in order to reduce the damage caused by the collision and extrusion of the fruit during transportation, the fruit is usually packaged in a bagging manner. Specifically, a foam net is usually placed on the surface of the fruit to make the foam The net plays the role of protection, thereby reducing the damage rate of the fruit.

When packaging fruits, there are usually two packaging methods: manual bagging and machine bagging. Among them, manual bagging is artificially stretching the foam net, stuffing the fruit into the foam net or putting the foam net on the fruit, so that the foam net wraps the fruit. However, the artificial bagging method is inefficient , the labor cost is high, and it is difficult to apply to large-scale fruit bagging;

At the same time, machine bagging is the use of machines for automatic bagging, which has a high degree of automation, can greatly reduce labor costs, and can improve fruit packaging efficiency.

However, although the use of machine bagging can greatly improve the packaging efficiency, the inventors have found that there are still deficiencies in the current process of using machine bagging, specifically:

Currently used packaging machines usually stretch one or both ends of the foaming net when expanding the foaming net, and the degree to which the end of the foaming net is stretched is usually greater than or equal to the maximum cross-sectional area of the fruit. In order for the fruit to enter the foaming net through the end of the foaming net, as in the Chinese patent application number CN202111250561.3, the opening claws of the net sleeve also push the net sleeve pressing block in the same direction while stretching the fruit net sleeve Movement: After reaching the predetermined position, the upper end of the fruit net sleeve opens a suitable opening, and is acted by the second compression spring, the second compression spring presses the guide plate of the net sleeve and the fruit net sleeve to the vertical position of the opening claw of the net sleeve. At this time, the lifting mechanism moves down and resets, the lock tongue group and the buckle are locked, and the net cover is opened and the claws are kept in an outwardly squeezed and opened state, which is convenient for fruit dropping at the fruit dropping station in the later stage; and the application number is CN201611125016 In the Chinese patent of .0, when the cone is lifted, the nylon rollers and the cone work together to transport the continuous net sleeves on the cone down and put them on the four support rods. When the length of the net reaches the package When the length of the fruit is required, the rotation of the first cam will make the four supporting rods descend, and the net cover will fall and be placed on the fruit on the conveyor belt.

The way that the net cover in the above two patents is stretched is that before bagging, one or both ends of the net cover are stretched to a greater extent, so that the fruit can be put into the foaming net. However, the currently used foam nets are usually made of polyethylene material. In the process of the foam net being stretched, the foam net recovers when the foam net is stretched for a long time and the foam net is stretched for a short time. The speed of the foam net is different, and the deformation recovery speed of the foam net is relatively slow when the foam net is stretched for a long time; and before the fruit falls into the foam net, one end of the foam net and the middle part of the foam net are close to each other. And the foaming net is stretched in advance so that the fruit falls in, so that one end of the foaming net and the middle part of the foaming net are in a state of being stretched for a long time, which reduces the stretching of the foaming net. The cross-section gap between one end of the foam net and the middle part of the foam net, in a short period of time after the fruit bag is bagged, it takes a certain time for the foam net to recover from its deformation, making it easy for the fruit to move to the stretched end of the foam net or even move from the foam net. The stretched end of the foam net comes out, especially when the fruit is transported in a short period of time after bagging, the section of the stretched end of the foam net and the middle of the foam net is usually still at a small gap. In some cases, when the movement of adjacent fruits drives the foaming net on the fruit to move, it is easier to separate the foaming net from the fruit, which is not conducive to the protection of the fruit by the foaming net.

Therefore, based on the above problems, there is an urgent need to design a fruit net cover expansion component and fruit packaging equipment to reduce the probability of the foam net falling off the fruit, thereby improving the protective effect of the foam net on the fruit.

The suction cup assembly 1 includes a first suction cup 3 and a second suction cup 4, the first suction cup 3 and the second suction cup 4 are used to absorb the outer surface of the foaming net 5, and the foaming net 5 and the second suction cup The outer surface corresponding to a suction cup 3 and the outer surface corresponding to the second suction cup 4 on the foam net 5 are opposite to each other, and are the first suction cup 3 and the second suction cup that move backwards from each other. The suction cup 4 is used to stretch the foam net 5, so that the foam net 5 forms an opening;

The brace assembly 2 includes two opposite braces 6, the braces 6 are used to extend into the opening and stretch the foam mesh 5 from the inner side of the foam mesh 5;

The upper, middle and lower parts of the brace 6 are sequentially the upper part 7 of the brace 7, the middle part 8 of the brace and the lower part 9 of the brace, the width of the upper part 7 of the brace is smaller than the width of the middle part 8 of the brace, and the The width of the part farther away from the middle part 8 of the brace on the upper part 7 of the brace is smaller; the width of the lower part 9 of the brace is smaller than the width of the middle part 8 of the brace, and the distance between the lower part 9 of the brace The farther part of the middle part 8 of the support plate is, the smaller its width is;

And the brace 6 is a concave structure, the inside of the brace 6 is a concave surface 10, and the outside of the brace 6 is a convex surface 11, when the brace 6 stretches the foam net 5, the The convex surface 11 faces the inner surface of the foam net 5 .

In this application, the expansion assembly includes a suction cup assembly 1 and a stretcher assembly 2, while the first suction cup 3 and the second suction cup 4 on the suction cup assembly 1 stretch the foam net 5 from the outer side of the foam net 5, so that The foam net 5 forms an opening so that the subsequent strut 6 can extend into the foam net 5 from the opening. The upper, middle and lower parts of the strut 6 in this application are the upper 7 of the strut, the middle 8 of the strut and the strut The lower part 9, and the width of the upper part 7 of the support plate is smaller than the width of the middle part 8 of the support plate. width, and the part of the lower part 9 of the brace 9 that is farther away from the middle part 8 of the brace is smaller in width, so that the upper and lower ends of the brace 6 are pointed or arc-shaped, on the one hand, it is convenient for the brace 6 to extend from the opening. On the other hand, when the two struts 6 extend into the foaming net 5 and stretch the foaming net 5, because the middle part 8 of the struts is wider, the foaming net 5 is in the braced position. When in the open state, the deformation of the middle part is the largest, and the deformation of the two ends of the foaming net 5 is the smallest; at the same time, the stretching plate 6 is a concave structure. The distance between them is greater than the distance between the lower parts 9 of the two braces and the distance between the upper parts 7 of the two braces, so that the corresponding cross-sectional area of the foam net 5 when stretched by the upper part 7 of the brace is smaller than that of the foam net 5. 5 corresponds to the cross-sectional area when stretched by the middle part 8 of the stretcher, and the cross-sectional area corresponding to the foam net 5 when stretched by the lower part 9 of the stretcher is smaller than that corresponding to the foam net 5 when stretched by the middle part 8 of the stretcher The cross-sectional area of the time, so as to further make the two ends of the expanded foam net 5 close up; in the process of fruit bagging, the fruit gradually enters the two support plates from the area between the lower parts 9 of the two support plates 6, at this time, due to the distance between the two braces 6, the part of the foam net 5 that is not in contact with the brace 6 is prone to deformation, so that the corresponding brace on the foam net 5 can The cross-sectional area formed by the part of the lower part 9 of the plate is smaller. When the foam net 5 is stretched, the degree of stretching of the part corresponding to the lower part 9 of the stretcher plate on the foam net 5 can be reduced. During the process of entering the fruit, the part of the foam net 5 that is not in contact with the stretcher 6 can be deformed to the surface of the fruit. At the same time, because the stretcher 6 has a concave structure and the width difference , so that the middle part 8 of the stretching plate can greatly reduce the probability of the stretched foam net 5 sliding relative to the stretching plate 6, thereby preventing the foaming net 5 from falling out of the stretching plate 6 during the process of inserting the fruit, and It is easy to deform the end of the corresponding support plate lower part 9 on the foam net 5, so that the foam net 5 can be placed on the fruit more quickly and stably, and the support plate 6 can be removed from the foam net more quickly and stably. 5 is taken out in the middle. In this application, there is a large difference in the degree of stretching between the middle part of the foaming net 5 and the two ends, so that the degree of stretching the middle part of the foaming net 5 is relatively large. At the same time, the supporting plate middle part 8 can improve the static firmness of the foaming net 5 relative to the supporting plate 6, so that the bagging of the fruit can be completed more quickly and firmly, and the expansion of the expanded foaming net 5 in the bagging process can be achieved. The time when deformation takes place is shorter, and it is easy to make the foaming net 5 recover from deformation after stretching in a short period of time, so that it is easier to cover the fruit at the two ends of the foaming net 5 that is placed on the fruit, thereby improving Improve the firmness when foaming net 5 is set on fruit, thereby improved the protective effect of foaming net 5 to fruit.
