Description

Continuous incising method on agricultural mulching film using tension spring and apparatus

The present invention relates to a method and apparatus for forming a continuous sheath of agricultural mulching film using a tension spring, and a device for cutting the mulching film at regular intervals without interrupting the supply of the mulching film produced in detail. It is about.

In general, mulching films are used in rural areas to help grow vegetables, grains and fruits that are planted in fields.

These mulching films cover the land where the crops are growing to protect the roots of the crops, maintain the temperature of the land, and prevent the soil from drying, pests, and weeds.

Figure 8 shows an example of a conventional mulching film, the conventionally produced mulching film punching a circular hole in the produced film, or just cover the ridges of the field where the crop is grown, the position when the crop grows I used a knife or hand to make an incision to take the crop out of the gap and help it grow.

However, as a disadvantage of the mulching film having a circular hole as shown in FIG. 8, the perforated area is wide, and not only crops but also weeds grow on the perforated surface, so that there is a disadvantage in that a separate weed removal operation is required.

In addition, there is a lot of problems in the case of the rural labor force, in which a man directly cuts the mulch film, which is not punched, in the field where the crop is grown.

In addition, the method of punching on the existing mulching film as described above has a disadvantage that a separate work that needs to be punched using a punching machine on the previously produced mulching film is required.

An object of the present invention for solving the above problems is to provide a method and an apparatus capable of cutting the mulching film while receiving the mulching film continuously in the same line as the mulching film production.

The purpose of the present invention as described above is to install the tension springs at both ends of the cutter device, so that each tension spring is moved up and down alternately according to the tension force that changes depending on the movement of the mulching film while the cutter device is lowered to stop the mulching film. It is achieved by providing a method and apparatus for producing a continuous mulching film and a continuously feeding mulching film during deformation without appearance deformation.
