A net cover is required to be coated outside a plurality of existing fruits such as apples and oranges so as to avoid fruit collision. However, the following problems exist in the fruit net packaging process:

1) the existing fruit feeding mechanism generally aims at round and similar round fruits, and when the fruit feeding mechanism is applied to oblong fruits, the fruit clamping phenomenon is caused frequently due to overlong fruit type length, so that the fruits are damaged and waste is caused.

2) The existing net sleeve cutting device is cut off by resistance wire hot melting, harmful gas can be generated when the net sleeve is fused at high temperature in the mode, the harm to human health is caused, and special protection is needed so as not to cause fire. Although some cutting methods adopt a blade cutting mode, the wear is fast and the service life is short.

3) The net sleeve is propped open in a large range in the length direction of the net sleeve when fruits are loaded, the original elasticity of the net sleeve is damaged, and even if the fruits are sleeved by the net sleeve, the fruits are easy to fall off in the subsequent loading and transportation processes, so that the purpose of protecting the fruits from being bruised by the net sleeve is lost.

4) The existing net sleeve packaging equipment is high in cost, is not suitable for small-batch packaging, still adopts manual packaging for the small-batch packaging, and is low in efficiency and high in labor intensity.

Patent "201920030577.5" a net cover fruit machine ", which is the preliminary idea of the applicant, the technology is not mature: 1) if the feeding mechanism adopts the conveying roller for conveying, the single conveying one by one cannot be ensured, and the uniform and vertical direction of the falling back cannot be ensured aiming at the oval fruits, so that the fruits are easy to clamp; 2) the net sleeve supporting device is used for the conveying and shearing mechanism, but the net sleeve supporting device cannot play a role in preliminarily propping the net sleeve, the net sleeve is pushed and passively propped by a spring in the rising process, the opening material port is single, active adjustment cannot be carried out, and the conveying and shearing mechanism cannot adapt to the use of fruits with different sizes and shapes. In addition, the spring can lose efficacy after a period of use, so that the net cover supporter loses the proper function. 3) The used driving devices are many, the energy consumption is large, only one material fruit can be packaged at one time, and the efficiency is low.

The invention relates to a fruit net sleeve efficient sleeving device and method, which have the following technical effects:

1) aiming at the oval fruits, the fruit feeding direction of the oval fruits can be changed, so that the oval fruits vertically pass through the fruit feeding port with the minimum diameter, and the fruit clamping is avoided; the cover plate always fixes the fruits in the fruit support when the fruit support is turned over, so that the fruits are prevented from rolling and falling randomly and are delivered accurately; because the device adopts the apron to press from both sides tightly, the opening size accessible reset spring round pin is adjusted between apron and the fruit support, the feeding of adaptable certain size within range fruit, can be fit for most fruit types simultaneously, has the commonality.

2) By adopting the supporting table and the net sleeve supporter, the fruit net sleeve can be in an open state during conveying, the fruit net sleeve can be conveniently sleeved on the net sleeve opening hook claw at the later stage, the fruit net sleeve can be directly clamped and tensioned, the upward movement stroke of the fruit net sleeve is accurately controlled, the net sleeve opening hook claw only opens the upper end part of the fruit net sleeve, most of the net sleeve for coating fruits is not expanded, the coating elasticity of the fruit net sleeve is ensured, and the fruit net sleeve is not easy to fall off in the subsequent packing and conveying processes; meanwhile, in the fruit net cover conveying process, the fruit net cover is clamped by the clamp and moves upwards together with the movable net cover support, and the fruit net cover is not excessively tensioned in the conveying process, so that the fruit net cover keeps the elasticity; in addition, by adopting a blade shearing mode, compared with resistance wire hot melting cutting, the cutting device is safer and more reliable and has no peculiar smell.

3) The diameter of the expanded net sleeve can be flexibly controlled by controlling the stroke of the grid; the length of the net cover can be controlled by adjusting the vertical distance between the cutter group and the station disc and the stroke of the ball screw. If the length of the net sleeve needs to be increased by 20 mm for packaging big fruits, three steps (1) are required: the whole cutter set is adjusted downwards by 20 mm. (2): and adjusting the zero position of the screw rod sliding table downwards by 20 mm. (3): the stroke of the screw rod sliding table is increased by 20 mm. The whole process is very convenient and fast.

4) The plurality of net sleeves can be driven to open the hook claws and open or close in a linkage manner through the grids, the connecting rods and the like, and meanwhile, the net sleeve pressing block is driven to act, so that the fruit net sleeves are clamped or loosened, the station disc is compact in structure, few in driving equipment and energy-saving.

5) Compared with the existing foreign equipment, the device has the advantages of low cost, greatly improved efficiency and reduced labor intensity compared with manual packaging. In addition, this application is more nimble on structural arrangement, and the equipment shown in this application figure 1 is small-size equipment, and 6 station dishes (every 3 station dishes are a set of, and 1 station dish opens the net cover, and 2 station dishes advance the effect, and 3 station dish unblocks) 2 station groups. Of course, the number of stations may be increased or decreased as required by the throughput. The design is 2 groups or 2 times of groups, and the maximum can be 20 groups. The equipment not only can be suitable for small-batch packaging, but also can enlarge the production capacity by increasing stations.

The fruit support 1.2 comprises an upper support plate and a lower support plate, the upper support plate is arc-shaped and made of flexible materials, and the upper support plate and the lower support plate are detachably connected. The upper supporting plate made of flexible materials can avoid damage when fruits fall down. Or the fruit support 1.2 can also be a simple supporting plate with an arc-shaped groove, and a layer of flexible sponge or flexible leather is added in the arc-shaped groove.

The working state and principle of the feeding mechanism 1 are as follows:

1) when a fruit needs to be fed, the first telescopic mechanism 1.5 extends out, and the cover plate 1.4 is opened to be turned upwards as shown in fig. 3.

2) As shown in fig. 4, the fruit is conveyed by the conveyor belt and enters the fruit tray 1.2, and then the first telescoping mechanism 1.5 retracts. Under the action of the return spring pin 1.6, the cover plate 1.4 is returned and pressed down on the fruit.

3) And as shown in fig. 5, the turnover mechanism 1.3 drives the fruit tray 1.2, the cover plate 1.4 and the like to integrally rotate for 90 degrees, so that the fruit tray 1.2, the cover plate 1.4 and the like are in a vertical state.
