Description

Agricultural packaging film and automatic production system thereof

Technical Field

The utility model relates to an agricultural product field especially relates to an agricultural packaging film and automatic production system thereof.

Background

The prior art is the Zlock patented technology of tamplastic corporation, israel. The technique is to divide a 500 m long plastic film into 24 pieces, each of which is wrapped with a crop into cylindrical rolls having a diameter of 60-230 cm and a width of about 2.7 m. The corresponding harvesting machine is an automatic harvesting machine of john diel, usa, and when a separation signal is met, the feeding film roll can be automatically braked, the crop packaging roll does not break the connecting buckle of the film, and then the film is automatically input to manufacture a new packaging roll, as shown in fig. 1, when the machine is used and crops are packaged, the front and rear units 1 and 2 of the packaging film are separated after braking at 10, and are adhered to two fractures 4 by using a Z buckle 3. The simple version also makes complex Z buckles as V-shaped interfaces.

The original technique cuts off the film, then bonds the Z button on two fracture, winds up the connected film, and then makes the next joint. Multiple joints are required for one product. The z-button is designed skillfully, has good adhesive force and enables the membrane to be normally conveyed, but can be easily disconnected after the signal collecting machine brakes. Because the shape of its knot is Z or V-arrangement, the direction of power is outwards stretched, and the adhesion was very tight when pulling force was not big at ordinary times, but when the pulling force increased to certain dynamics, must break off, so the viscosity of gluing can be very big, and the reliability is very good. Besides the sticking, the button also has the function of tightly wrapping the crop roll, namely, the glue remained on the film is needed to tightly stick the tail end of the crop roll.

This technique has a number of significant drawbacks:

1. the manufacturing procedure is complex, and the film is required to be cut and then adhered; the process flow generally comprises the following steps:

1) cutting the packaging film at the waist blocking angle of 90 degrees;

2) the unit 1 is folded back by 180 degrees (length 200mm), and then the unit is clamped by a mold and folded back;

3) the Z-shaped button is stuck on the folded film of 200mm of the unit 1, the button and the folded film are aligned by a mould, and the Z-shaped button is slowly pressed down and stuck tightly;

4) because the lower buckle is provided with glue, the unit 2 is rolled forward, the unit 2 moves 200mm to cover and stick on the Z buckle, the unit 1 keeps still, and the unit 2 is dragged to be suspended and aligned in the air;

5) the tail end of the Z button is reversely folded by 180 degrees, is stuck on the upper end of the unit 2, and is inserted, buckled and reversely folded to stick the unit 2, so that the mechanization is difficult;

6) the Z buckle is reversely paved into a whole and is slowly rolled into a product scroll, and the buckle must be unfolded in the packing direction along the packing direction during packing, so that the buckle can be smoothly unfolded on the harvester. This step is troublesome when the film is too soft and is not shaped, and the press is corrected after the mold is clamped.

The prior art production flow is very difficult to realize each step mechanically in production. Therefore, the current imitators in China are finished manually, which is time-consuming, slow in speed and low in yield. Several other steps, except the first step of cutting the film, are difficult to automate instead of manually. Since the film is nearly 3 meters wide and very thin, it is difficult to shape. And in the step 2, the folding back needs to be carried out by clamping with a mould;

2. glue is brushed on a production line to pollute the production line, and the operation site is difficult to clean;

3. the production speed is slow, and the efficiency is low;

4. the product percent of pass is low.

All the above operations are time consuming and require high mechanization.

Therefore, it is necessary to provide a technique for producing and using a crop packaging film.
