Description

Corrugated pad corrugated cardboard manufacturing apparatus {Manufacturing device of corrugated paper}

The present invention relates to an apparatus for producing cardboard.

In particular, the present invention relates to a corrugated corrugated cardboard manufacturing apparatus of an improved function which is provided for product packaging for safe transportation and storage of various high-precision electronic products and the like and has an environmentally friendly nature.

In general, styrofoam, which has low weight and is excellent in processability and cushioning, is mainly adopted to package articles to be transported and stored while being protected from climate change such as external impact or moisture. As the external form is processed to fit the external shape and tightly fixed in a separate packing box, the built-in product is provided to be protected from external shocks, foreign substances, and moisture. It has also been proposed to provide a foamed plastic wrapping paper in which a plurality of air layers are formed closely to be protected by wrapping the corresponding product.

However, each product packaging material is a primary target of the regulation recommended to reduce the production and use of each country due to the non-environmental nature of the product packaging material, and a new packaging material is urgently required to replace it.

In other words, each product packaging material has a unique characteristic of synthetic resin, which makes it difficult to dispose and recycle and has high manufacturing and molding costs. .

Corrugated cardboard structure is interwoven with corrugated cores that are bent in a sine or non-signal shape between the upper and lower base sheets of paper, and is very light overall, environmentally friendly, and recycled after use. It is obvious that this is a viable alternative to the synthetic resin packaging material.

However, in order for the above packing material to have sufficient buffering and to protect the internal items from the surrounding moisture and foreign matter safely, the height width of the corrugated core will have to be remarkably enlarged. When the wrinkles of the core core are bent or pressed by an external impact, the original purpose of the function cannot be exhibited at all.

In order to overcome this problem, a structure of stacking a plurality of corrugated sheets is inevitably adopted, but the lamination work is not only inconvenient but also adds another corrugated cardboard to the finished corrugated cardboard. Due to the space and cushioning is blocked by the upper and lower base sheets, it causes a failure in the function of the predetermined function, the workability is also poor, accompanied by many difficulties in the processing of curved surfaces or corners.

As described above, as the number of stacked sheets increases as the base sheets are placed between each corrugated core, the weight is increased, and the water-soluble bond applied is excessively required, so a new alternative method for packaging is required.

Therefore, in order to solve the above problem, the present invention has been conceived of a corrugated pad system for winding a corrugated cardboard on a semi-finished product in which a corrugated core is formed on a base sheet of one side in a circular and elliptical shape.

Corrugated corrugated cardboard manufacturing apparatus of the present invention can manufacture a wide variety of sizes, thicknesses, widths and shapes freely in a short time according to the characteristics of the desired product, freely curved or edged with excellent buffering and easy processing, and beautiful appearance First of all, the object of the present invention is to provide the usefulness that the external impact is distributed and absorbed evenly by the present invention wound in a multi-layered form, thereby significantly increasing the stability of the embedded product.

The present invention provided for achieving the above object is a plurality of transporting rollers rotatably installed on a support frame so that a series of wound first base sheet can be released and supplied sequentially, and the position facing the first base sheet. And a plurality of transport rollers which are also rotatably mounted on the frame so that the rolled up sheet of paper can be sequentially unwound and fed in the longitudinal direction to bend the supplied paper into a sine or non-signal corrugated core shape. After forming the outer periphery of the core in the form of a core core, the forming roller is driven by a separate power generating means, and the protruding wrinkle portion of the original paper processed and supplied in the form of the core core is contacted and applied near the forming roller The adhesive filled into the first base sheet and the wrinkles to which the adhesive is applied are closely related to each other. And a pressure roller provided in the shaping roller and the opposite position so that the adhesive is incorporated, the first processing means including a take-up roller in order to recover the corrugated subjected to the pressure roller; After taking out and mounting the corrugated paper wound through the first processing means, the sheet is wound in a circular shape so that the wrinkles face inwardly with a predetermined thickness and width, and the corrugated corrugated wound wound is applied in contact with the filled adhesive of the base sheet. A second processing means adapted to be closely attached to the outer surface to be cut; Third processing means for press-pressing the molded cardboard into a required cross-sectional shape by winding it to a predetermined thickness through the second processing means; And connecting and assembling each corrugated pad corrugated cardboard passed through the third processing means so as to be suitable for transporting the product, and the fourth processing means for finishing cutting is sequentially provided.

The first processing means 10 requires the most basic and largest production equipment for the manufacture of corrugated cardboard, and the reliability of the finished product packaging material will be determined mostly through the first processing means 10.

Firstly, the first base sheet 1 of a rolled sheet of rolled shape is laid down and then sequentially released to be supplied at an arbitrary speed (the speed control driven by the control panel can be variably adjusted). A plurality of feed rollers 2 are pivotally mounted on the frame A so that a first roll of the rolled base paper 3 is positioned at the position facing the first base sheet 1. A plurality of transport rollers 4 are also provided on the support frame A so as to be rotatable so that they can be sequentially unwound and supplied at the same driving ratio as in (1). Since wrinkles are processed to be integrated in 1) to form a corrugated core, it is generally desired to maintain a winding rate of about 1.6 times that of the first base sheet 1.

The supplied base paper 3 is bent in the form of a corrugated core as described above, so that the shape of the sine or non-signal folds 3a can be maintained, and for this purpose, the outer periphery of the longitudinal direction is formed into a corrugated core. The roller (5) is built up to be driven by a separate power generating means, the base paper (3) can be processed in the form of a continuous corrugated (3a) by being in close contact with the molding roller (5) and a separate pressure roller. In addition, the water-soluble adhesive (6a) to the frame storage box (6) near the forming roller (5) as shown in Fig. 2 (a) so that the top protruding surface of the core core can be applied while contacting (passing) during transportation. It is filled in a predetermined cycle through the supply nozzle from the outside, through which the first base sheet (1) and the corrugated paper base (3) to which the adhesive is applied are respectively closely bonded to each other and integrated. Could be sufficiently achieved by the pressure roller 7 at a position opposite to the forming roller (5).

The semi-finished corrugated cardboard 8 in which the corrugated core is formed is thus caught and recovered by a separate winding roller 9 through a plurality of transfer rollers to finish the first processing means 10.

FIG. 3 shows a second processing means that is addressed to the first processing means, and withdraws and mounts a semi-finished corrugated cardboard 8 wound in a roll shape through the first processing means 10 to be appropriate as necessary. It draws the length and wound (wound) circular and elliptical shapes so that the portion of the wrinkles 3a is inwardly inwardly with a predetermined thickness and width, and the wrinkles 3a of the corrugated core to be wound are filled in the lower end thereof. The second processing means which is closely attached to the outer surface of the rear part of the first base sheet 1 which is coated and continuously applied and is in contact with each other and is fixed so as not to be released freely. 20) is to be provided in a subsequent process, taking into account the shape of the product to be taken out and packaged by the cut cardboard 21, which is wound to a predetermined thickness through the second processing means (20) The third processing means 30 is press-pressed in order to form a required cross-sectional shape such as one (c) according to the shape of the product, and the third processing means (as shown in the embodiment of FIG. 4). The fourth processing means 40 is finally prepared by connecting and assembling each cardboard 21 passed through 30 into a required shape to suit the transportation of the product, and then finishing cutting work. Slotted packaging materials for carrying related parts may be provided in various ways.

Therefore, the present invention can freely manufacture a cardboard packaging material suitable for the characteristics of the product in a fast process, excellent cushioning and workability, freely curved or edged treatment, improve the appearance and at the same time the external impact is multilayered Due to the structural properties wound in shape, it is useful in the industry that it is properly dispersed and absorbed to double the stability of the embedded product when used as a product packaging material.
