Embodiment Construction

[0028] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0029] The present invention simplifies these complex processes to only use two pieces of double-sided adhesive tape to install on one side of the dividing line 211, and utilize the contact during winding to connect the front and rear units naturally. When unwinding, the circular rotation force is also automatically used to separate the double-sided adhesive tape and the release film 13 at the tangent point of the circumference, so that the double-sided adhesive tape on the two units is separated. When unwinding, the separation directions of the two double-sided adhesive tapes at the circumferential tangent point are opposite, so the single release film 13 can be eas...

Abstract

The invention provides an automatic packaging roll for crops and a manufacturing method of the automatic packaging roll. The packaging roll comprises inner-layer double-faced adhesive tape wound on the outer side of a winding drum; a release film arranged on the outer side of the inner-layer double-faced adhesive tape; and outer-layer double-faced adhesive tape arranged on the outer side of the release film. The release film is bonded with the outer surface of the inner-layer double-faced adhesive tape and is not bonded with the inner surface of the outer-layer double-faced adhesive tape, easy-to-tear lines formed by different punched holes are arranged between the double-faced adhesive tape and the release film which belong to different units, and base materials of the front unit and the rear unit are PE films. According to the automatic packaging roll for the crops and the manufacturing method of the automatic packaging roll, separation of different units and automatic exposure of a sealing rubber surface can be achieved under the condition that no additional structures of buckles or bridges are added, so that crop bundles are wrapped.

Description

technical field [0001] The invention relates to the technical field of agricultural product packaging, in particular to an automatic packaging roll for agricultural products and a manufacturing method thereof. Background technique [0002] This technology is a supplement to the utility model patent "an agricultural packaging film and its automatic production system" (patent number: 202020647408.9), mainly adding a new technology of bonding the tail of the packaging roll. The existing technology and process is to divide hundreds of meters of plastic film into more than 20 pieces, and each piece wraps a crop into a roll with a diameter of more than 200 centimeters, and the width of the roll film is about 2.7 meters. The corresponding harvesting machine is the automatic harvesting machine of John Deere in the United States and similar large-scale harvesting machines. When encountering a separation signal, it can automatically brake the supply film roll, keep the crop packing ro...
