Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The utility model discloses simplify these complicated technologies into only installing in one side of cut-off rule 211 with two double faced adhesive tapes, two units around the contact natural connection when utilizing the preparation rolling. When unreeling, the double-faced adhesive tape and the release film 13 are automatically separated at the tangent point of the circumference by using the circumferential rotating force, so that the double-faced adhesive tapes on the two units are separated. When unreeling, the two double-sided adhesive tapes are separated in opposite directions at the circumferential tangent point, so that the single release film 13 can be easily separated. The old technology must use 180 degree reverse folding release film 13 because the separation is done in the same plane and the reverse shear resistance is large. The utility model discloses make the automatic simple process who pastes the tail and glue of completion, the material reduces, and efficiency improves.

The wrapping film of certain length is according to rubber coating film and the rolling of light film during the preparation to it is certain length's light film parcel crops earlier when launching, then the rubber coating film is wrapped up in the periphery tightly. As shown in fig. 1, the front unit 21 is an optical film, and the rear unit 22 is an adhesive film. The perforation line 211 is the separation line between the two films, and when the unwinding spool 111 is braked and the wrapping roll 32 continues to rotate, the perforation line 211 tears and the rear unit 22 separates from the front unit 21, which is the front film of the next package.

The inner double-sided adhesive tape 12 and the outer double-sided adhesive tape 14 are overlapped with a release film 13 therebetween, and the inner double-sided adhesive tape 12 may have a smaller area than the outer double-sided adhesive tape 14 because the outer double-sided adhesive tape 14 mainly functions as a package. The upper layer of the release film 13 is not separated from the shape and is stuck with the inner layer double faced adhesive tape 12. The lower layer of the release film 13 is separated from the outer layer double-sided adhesive tape 14 during unreeling and packaging. The outer double-sided adhesive tape 14 is stuck to the packaging film at the lower side. The double-sided adhesive tape structure is prefabricated into a roll shape and is vertically spread on a packaging film by 90 degrees when in use. When the double-sided adhesive tape is unfolded, the top layer of the glossy paper is uncovered, so that the adhesive surface of the inner-layer double-sided adhesive tape 12 is exposed. The preform is placed behind the perforation line 211 on the side of the unit 22, i.e. on the left, which will constitute the tail seal of the package.

And the contact point of the wound inner layer double-sided adhesive tape 12 and the front unit 21 after being wound on the winding drum 11 is stuck. Thus, the rear unit 22 and the front unit 21 are naturally and neatly connected at random when being wound and rotated. The prior art requires special connections and a plurality of programs. When more than 20 packaging films are continuously collected into a large roll, the product is manufactured. The roll has no Z button and no hole bridge in the prior art, particularly, 5 m tail joints are subtracted from the final axis, so that the material is greatly reduced, and the process is simple.

Since the rear unit 22 and the front unit 21 are randomly connected, the distance between the inner double-sided adhesive tape 12 on the front unit 21 of each packaging film and the perforation dividing line 211 is unequal, but the function of the product is not affected. The diameter of the finished roll is increased from 14 to 25 cm during manufacture, and the diameter of the reel 11 multiplied by the circumference ratio when the wrapped crop is unwound from the harvesting machine is the distance between the two pieces of double-sided adhesive of the film. The inner layer double-sided adhesive tape 12 only plays a role of covering on the pulling tail adhesive tape, and the covering is the release film 13. More than 20 double-sided adhesive joints are contained in a finished roll, which is a very round, straight cylinder because of its negligible thickness. The diameter of the final product is slightly smaller than that of the original product using the buckle or bridge technology, and the new technology can also be used as a packaging unit, so that the capacity of the new product is increased.

As shown in fig. 3, when the harvester wraps the crops, the wrapping film travels in the direction of wrapping the crops when the finished rolls are unwound. The double-sided adhesive tape buckle is naturally separated at the tangent point, where the release film 13 on the outer double-sided adhesive tape 14 is taken away by the inner double-sided adhesive tape 12, because the release film 13 is detached from the outer double-sided adhesive tape 14 and is not detached from the inner double-sided adhesive tape 12. 13 and 12 remain on the membrane. The glue surface of the outer layer double-sided adhesive tape 14 is exposed, and the crop roll 32 is stuck at the tail end after reaching the crop roll packet 32, so that a crop wrapping cycle is completed. After the film is torn at the perforated line 211, the inner double-sided adhesive 12 is left at the front end of the subsequent film to be ready for the next wrap to start. As shown in fig. 4.

The production process comprises the following steps:

1. stripping the glossy paper on the long strip of the outer layer double-sided adhesive tape 14, and coating the release film surface of the long strip of the release film 13 on the outer layer double-sided adhesive tape 14 to align;

2. laying an inner layer double-sided adhesive tape 12 on the non-release surface of the release film 13, and aligning;

3. a neat strip of the release film 13 is sandwiched between the two layers of double-sided adhesive tapes for winding, and the outer layer of double-sided adhesive tape 14 is positioned at the outer layer;

4. pausing at a workbench in the winding production process of the packaging film PE, punching an easy-to-tear line 211, wherein the winding direction is that the rear unit 22 flows to the front unit 21;

5. rolling a double-sided adhesive tape prefabricated roll 23 at the position, close to the easy-tearing line 211, of the rear unit 22, unreeling, peeling off the glossy paper from the outer-layer double-sided adhesive tape 14 at the moment, and sticking the adhesive surface and the rear unit 22 film;

6. stripping the glossy paper of the inner double-sided adhesive tape 12 on the upper layer to expose the adhesive surface;

7. rolling is started in the manufacturing process, and the direction is that the rear unit 22 flows to the front unit 21;

8. when the roll 11 is encountered, the inner double-sided tape 12 comes into contact with the front unit 21, and this contact point is a point after the film of the front unit 21 rotates one turn, and naturally sticks to the dead. The easy-to-tear line 211 is positioned between the inner double-sided adhesive tape 12 and the outer double-sided adhesive tape 14;

9. the successive production process is generally made up of more than 20 packing units, each unit consisting of two elementary films and a double-sided adhesive preform. Normally, the rear unit 22 is a light film, and the front unit 21 is a mucous membrane coated with glue, and the product is finished.

The main advantages of the technology are:

2. the separation lines between the two units do not need to be aligned accurately, and the production is simple;

3. all parts and materials are placed in the rear unit 22;

4. the two units are connected by natural force, and the two units are separated by natural rotation force without manufacture or guidance;

5. the two units are connected without positioning and random adhesion, and the high quality is achieved by a fuzzy production mode;

6. the material is reduced, the production time is shortened, and particularly, 5 meters of tail films of the film roll can be saved.

As shown in figure 5, when the work of wrapping crops is finished, the novel technology needs less than 20 buckles or bridges in production, the time is reduced, the connecting materials are less, the stock space is reduced, and the total cost is greatly reduced. Especially, the length of each roll of tail film is not required to be 5 meters, the width of each roll of tail film is 2.7 meters, and waste is reduced. Because the method is simple and easy to implement, the training and requirements of workers are reduced, and the efficiency is improved.

The above description is only for the preferred embodiment of the present invention, and not intended to limit the present invention in any way, and those skilled in the art can make various modifications, equivalent changes and modifications using the above-described technical content, all of which fall within the scope of the present invention.
