Description

Technical Field

[0001] The invention relates to the field of paper box processing, and in particular to a laminating device for processing packaging paper boxes. Background Art

[0002] After corrugated cardboard is folded, it becomes a packaging carton. During the processing of packaging carton, it is necessary to cover the corrugated cardboard with plastic film to achieve the purpose of waterproofing and aesthetics. However, during the production, transportation and storage of corrugated cardboard, especially three-layer or more-layer corrugated cardboard, since it is a common item of low value and has a certain ability to resist impact, in most cases, manufacturers will only put multi-layer corrugated cardboard into transport boxes for transportation without adding special protection. Therefore, some multi-layer corrugated cardboard may suffer from collision and impact during transportation. In addition, multi-layer corrugated cardboard is continuously packed during the production process. When the strips are divided into multiple pieces according to the size of use, the cutting position may fall on the trough of the wavy corrugated paper. After cutting, the face paper or the inner paper opposite the trough will be suspended, lacking the support of the core paper, and there is a certain space between the face paper and the inner paper to allow deformation; eventually, the edge of the face paper or the inner paper will be slightly bent toward the core paper, causing the roller to not completely fit the curved edge of the cardboard when pressing the plastic film coated with glue on the cardboard, which makes the pressure of the roller on the curved edge of the cardboard small, and the roller cannot press the plastic film tightly against the curved edge of the cardboard, thus affecting the laminating quality of the cardboard. If repairs are made later, although the number of cardboards with this problem is small, the processing process is more troublesome due to the small area to be processed. On the other hand, the corrugated cardboard itself is not damaged, and direct disposal will cause a waste of resources. Summary of the invention

[0003] In order to overcome the disadvantages that the pressing roller cannot completely fit the curved edge of the cardboard during the laminating process, thereby making the pressing force of the pressing roller on the curved edge of the cardboard small and the pressing roller cannot fit the plastic film tightly to the curved edge of the cardboard, thereby affecting the laminating quality of the cardboard, the present invention provides a laminating device for packaging paper box processing.

[0004] The technical solution of the present invention is: a laminating device for processing packaging paper boxes, including a laminating machine; also including guide rails, moving blocks, fixed plates, supporting plates, electric push rods I, connecting plates, elastic sheets, electromagnets, electric suction cups, conversion components and positioning correctors; the laminating machine is connected to a plurality of guide rails; each guide rail is slidably connected to a plurality of moving blocks; all moving blocks located on the same guide rail are fixedly connected to a fixed plate; all fixed plates are commonly fixedly connected to a supporting plate; each fixed plate is fixedly connected to a plurality of electric push rods I; the telescopic ends of all electric push rods I located on the same fixed plate are commonly fixedly connected to a connecting plate; each connecting plate is connected to an elastic sheet; each elastic sheet is provided with a magnetic metal sheet; each connecting plate is fixedly connected to an electromagnet, and the electromagnet is located below the magnetic metal sheet; the supporting plate is fixedly connected to an electric suction cup; the fixed plate is connected to a conversion component for adapting to different sizes of cardboard bodies; the conversion component is connected to a positioning corrector for positioning and correcting the cardboard body.

[0005] As a further preferred solution, the elastic sheet is provided with an arc-shaped edge portion.

[0006] As a further preferred solution, the surface of the elastic sheet is smooth.

[0007] As a further preferred solution, there are several electric suction cups, and the electric suction cups are distributed in a rectangular shape.

[0008] As a further preferred embodiment, a heater is installed in the pressure roller.

[0009] As a further preferred solution, the surface of the supporting plate is smooth.

[0010] As a further preferred scheme, the transformation component includes a U-shaped plate and a rectangular plate; two fixed plates are commonly fixed with the U-shaped plate, and there are two U-shaped plates in total, distributed at both ends of the fixed plates; each U-shaped plate has two rectangular grooves; each rectangular groove on the U-shaped plate is slidably connected to a rectangular plate, and a power structure that can drive itself to move is provided on the rectangular plate.

[0011] As a further preferred solution, the positioning corrector includes an electric push rod II and a positioning block; each rectangular plate is provided with a number of slide grooves; each slide groove is slidably connected to an electric push rod II via a slider, and a power structure is provided on the slider; a positioning block is fixed to the telescopic end of each electric push rod II.

[0012] As a further preferred solution, a rubber pad is provided on the surface of the positioning block that contacts the paperboard body.

[0013] As a further preferred solution, the elastic sheet is detachably connected.

[0014] The present invention has the following advantages: the present invention controls the electromagnet to be powered off, so that the elastic sheet expands outward under the action of the rebound force, the bending degree is reduced, and the curved edge of the paperboard body is stretched from the inside to the outside. By manufacturing or adjusting the normal posture of the elastic sheet, the normal expanded posture is made to be a horizontal posture, thereby achieving continuous support for the curved edge of the paperboard body.

[0015] The present invention provides a plurality of electric suction cups, and the electric suction cups are distributed in a rectangular shape, so that the electric suction cups can adsorb and fix the four diagonal corners of the cardboard body. Compared with directly adsorbing the middle position of the cardboard body to fix it, a better fixing effect can be obtained, so that the four diagonal corners of the cardboard body remain stable.

[0016] The present invention can increase expansion adaptability by replacing detachable elastic sheets with different bending degrees and elastic coefficients. When faced with a variety of corrugated cardboards with large differences in thickness and number of corrugated layers, it is impossible to rely on one elastic sheet to adapt to all types. The elastic sheet can be set to a detachable connection so that it can be adaptively replaced according to different requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The laminating machine includes a fixed seat 1, a cylinder 2, a mounting plate 3, a pressure roller 4, a reeling roller 5, a rubber roller 6, a glue box 7 and a camera 9; the fixed seat 1 is bolted to the guide rail 101; the fixed seat 1 is bolted to two cylinders 2; each of the telescopic ends of the cylinder 2 is fixedly connected to a mounting plate 3; the surface of the fixed seat 1 is provided with a track rod which guides the mounting plate 3 to slide and supports the mounting plate 3; the two mounting plates 3 are connected to the pressure roller 4 for common rotation; the two mounting plates 3 are connected to the reeling roller 5 for common rotation; the two mounting plates 3 are connected to the glue roller 6 for common rotation; the two mounting plates 3 are fixedly connected to the glue box 7, and the glue box 7 is in contact with the rubber roller 6; a number of cameras 9 are fixedly connected to the fixed seat 1.

[0030] The elastic sheet 107 has an arc-shaped edge portion 1072 .

[0031] The surface of the elastic sheet 107 is smooth, which reduces the friction force when the elastic sheet 107 enters the inner side of the curved edge of the paperboard body 8 .

[0032] There are a plurality of electric suction cups 109 , and the electric suction cups 109 are distributed in a rectangular shape.

[0033] A heater is installed inside the pressure roller 4.

[0034] The surface of the supporting plate 104 is smooth, which reduces the friction force when the paperboard body 8 is pushed onto the supporting plate 104 .

[0035] When in use, the factory workers need to classify the two types of corrugated cardboards with and without bending at the edges through visual inspection. The corrugated cardboards without bending are coated normally, while the small number of corrugated cardboards with bending are coated using the present invention. First, the external infusion pump is connected to the glue box 7, and then the plastic film on the unwinding roller 5 is manually pulled out, bypassed by the rubber roller 6, and then wound around the pressure roller 4, so that the plastic film is tightened under the joint action of the unwinding roller 5, the rubber roller 6 and the pressure roller 4; then, the defective cardboard body 8 to be coated is manually placed on the supporting plate 104, with the side to be coated facing up and the side that may be deformed facing the direction of the fixing seat 1. The positioning corrector pushes the side of the middle paper in the multi-layer corrugated cardboard that is fixed by the corrugation and difficult to deform. The position of the cardboard body 8 is corrected in this way so that the cardboard body 8 is aligned with the plastic film on the pressure roller 4. After the correction is completed, the positioning corrector is actively hidden to avoid hindering the operation of other mechanisms. Then, the electric suction cup 109 is controlled to adsorb the cardboard body 8 on the supporting plate 104 for fixing. The initial electromagnet 108 is energized, and the magnetic attraction of the magnetic metal sheet 1071 causes the elastic sheet 107 to bend downward into a curved shape. The elastic sheet 107 accumulates elastic force at this time. Then, according to the direction of the edge where the problem occurs, the corresponding electric push rod Ⅰ105 is controlled to drive the corresponding connecting plate 106, the elastic sheet 107 and the electromagnet 108 to move toward the direction of the cardboard body 8 until the bent elastic sheet 107 extends into the inner side of the bent edge of the cardboard body 8, as shown in FIG. Figure 6 shown.

[0036] Next, the electromagnet 108 is controlled to be de-energized, and then the elastic sheet 107 is expanded outward under the action of the rebound force, the degree of bending is reduced, and then the curved edge of the paperboard body 8 is stretched from the inside to the outside, and the normal posture of the elastic sheet 107 is manufactured or adjusted so that the normal expanded posture is a horizontal posture, thereby realizing continuous support for the curved edge of the paperboard body 8; then, the guide rail 101 is controlled to make the moving block 102 drive the fixed plate 103 and the components thereon to move toward the direction of the pressing roller 4 until they completely pass through the pressing roller 4 from below the pressing roller 4. When the paperboard body 8 contacts the plastic film on the lower side of the pressing roller 4, because the plastic film itself is composed of a base film carrying an attached film and a pasting film, and the pasting film itself is a piece of separate film surface on the base film, and the interval between adjacent attached films is 1 to 2 mm, it is necessary to control the pressing roller 4 to start to rotate in a concomitant manner, continuously rewind the base film and at the same time stick the pasting film to the surface of the paperboard body 8.

[0037] Before this, when conveying the plastic film, it is necessary to control the rotation of the rubber roller 6 and control the start of the external infusion pump to convey the glue into the glue box 7, and the glue in the glue box 7 is smeared on the rotating rubber roller 6, and the rubber roller 6 then applies the glue to the pasting film, ensuring that the pasting film surface that contacts the cardboard body 8 at the beginning is evenly coated with glue; because the curved edge of the cardboard body 8 is supported by the elastic sheet 107 in advance, the curved edge will also return to a horizontal state, so that the plastic film is tightly attached to the edge of the cardboard body 8, thereby improving the quality of the film and avoiding the need for secondary repair later.

[0038] The camera 9 is used to observe and detect whether a cardboard body 8 has been pressed and coated. After a cardboard body 8 has been pressed and coated, the processed cardboard body 8 is manually taken away, and the pressing roller 4 continues to rotate at a predetermined angle to allow the plastic film to continue to be pulled out by 1 to 2 mm to ensure that the end of the new film can be attached to the end of the new cardboard body 8 to be processed. Then, the guide rail 101 is controlled to allow the moving block 102 to drive the fixed plate 103 and the components thereon to move back to the initial position, and the next cardboard body 8 is manually placed and fixed on the supporting plate 104, and the above action process is repeated to complete the film application operation.

[0039] Since each elastic sheet 107 is provided with an arc-shaped edge portion 1072 and the elastic sheet 107 is polished relatively smoothly, if the elastic sheet 107 contacts the edge of the face paper or the inner paper when penetrating into the paperboard body 8, the arc-shaped edge portion 1072 is less likely to get stuck and push the edge of the face paper or the inner paper, causing the face paper or the inner paper to curl further inward.

[0040] Since there are several electric suction cups 109 and the electric suction cups 109 are distributed in a rectangular shape, the electric suction cups 109 can adsorb and fix the four diagonal corners of the cardboard body 8. Compared with directly adsorbing the middle position of the cardboard body 8 to fix it, a better fixing effect can be obtained, so that the four diagonal corners of the cardboard body 8 remain stable.

[0041] In addition, a heater is installed in the laminating machine pressure roller 4, and when the plastic film passes through the pressure roller 4, the pressure roller 4 is heated by the heater, and the pressure roller 4 transfers the heat to the plastic film, thereby preheating the plastic film, improving the laminating effect of the plastic film on the cardboard body 8, and improving the adhesion stability.

[0042] Furthermore, the supporting plate 104 is smoothly configured to reduce the friction force when the paperboard body 8 is pushed onto the supporting plate 104 , thereby reducing the resistance of the supporting plate 104 to the paperboard body 8 , making the calibration work smoother. Example

[0043] On the basis of Example 1, Figure 4 , Figure 5 and Figure 7As shown, the transformation component includes a U-shaped plate 201 and a rectangular plate 202; two fixed plates 103 are fixedly connected with the U-shaped plate 201, and there are two U-shaped plates 201 distributed at both ends of the fixed plates 103; each U-shaped plate 201 is provided with two rectangular grooves 2011; each rectangular groove 2011 on each U-shaped plate 201 is slidably connected with a rectangular plate 202, and a power structure that can drive itself to move is provided on the rectangular plate 202.

[0044] The positioning corrector includes an electric push rod II 203 and a positioning block 204; each rectangular plate 202 is provided with two slide grooves 2021; each slide groove 2021 is slidably connected with an electric push rod II 203 through a slider, and a power structure is provided on the slider; each telescopic end of each electric push rod II 203 is fixedly connected with a positioning block 204.

[0045] A rubber pad is provided on the surface of the positioning block 204 that contacts the paperboard body 8 .

[0046] In order to adapt to cardboard bodies 8 of different sizes and to improve the adaptability of the laminating equipment, the operating steps of the conversion component in Example 1 are as follows: when the length of the cardboard body 8 in the left-right direction is greater than the supporting plate 104, the two rectangular plates 202 are controlled to move back to back on the U-shaped plate 201 until the rectangular plates 202 are located at the end area of ​​the cardboard body 8, and then the rectangular plates 202 support the end area of ​​the cardboard body 8. Since the cardboard body 8 is a multi-layer plate with a corrugated structure, it has a greater bending resistance. Even if the cardboard body 8 in the area between the rectangular plates 202 and the supporting plate 104 is not supported at this time, it will not be bent by the pressing roller 4.

[0047] The operation steps of the positioning corrector in Example 1 are as follows: after the cardboard body 8 is placed on the surface of the supporting plate 104, at this time, the connecting plate 106, the elastic sheet 107 and the electromagnet 108 are located outside the two adjacent positioning blocks 204 and are not located between the two positioning blocks 204, so as to avoid hindering the positioning blocks 204 from playing a pushing and positioning role. Then, the two electric push rods II 203 are controlled to drive the corresponding positioning blocks 204 to move upward until the two positioning blocks 204 extend out of the surface of the rectangular plate 202. Then, the electric push rods II 203 are controlled to move upward. 03 surface electric wheel and other power structures, two electric push rods II 203 on the same rectangular plate 202 move closer to each other, so that the positioning block 204 squeezes and pushes the two ends of the paper in the cardboard body 8, and then the cardboard body 8 is accurately placed in the middle position of the supporting plate 104, so that the cardboard body 8 is aligned with the edge of the plastic film on the pressure roller 4, and then the electric push rod II 203 is controlled to drive the positioning block 204 to move downward and retract into the rectangular plate 202 without interfering with the work of the connecting plate 106, the elastic sheet 107 and the electromagnet 108.

[0048] When facing corrugated cardboards with different numbers of layers, the cylinder 2 can be adjusted to rise and fall, the mounting plate 3 can be controlled to slide on the guide column, and the height of the pressing roller 4 can be adjusted to adapt to the corrugated cardboards with different layers and thicknesses.

[0049] Since the two positioning blocks 204 on the same rectangular plate 202 are respectively provided with rubber pads on the facing sides, the squeezing damage to the edge of the cardboard body 8 when the positioning blocks 204 push the cardboard body 8 is reduced, thereby reducing the deformation effect on the edge of the cardboard body 8. Example

[0050] Based on the second embodiment, the elastic sheet 107 is detachably connected.

[0051] The expansion adaptability can be increased by replacing detachable elastic sheets 107 with different bending degrees and elastic coefficients. When faced with a variety of corrugated cardboards with large differences in thickness and number of corrugated layers, it is impossible to rely on one elastic sheet 107 to adapt to all types. The elastic sheet 107 can be set to a detachable connection so that it can be adaptively replaced according to different requirements.

These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention.
