Description

Technical Field

[0001] The present invention relates to the technical field of corrugated paper production, and in particular to a corrugated board drying and shaping device and production line. Background Art

[0002] Corrugated board has good shock absorption, lightness and low cost due to its unique structure, and is widely used in the packaging field, especially in protecting products with arcs such as sofa armrests, plastic pipes, etc. The strength of corrugated board mainly comes from its wavy corrugated core paper. This structure increases the thickness and moment of inertia of the board, thereby improving its compressive and bending resistance. In actual applications, due to the anti-bending characteristics of flat corrugated board, it is impossible to directly press and produce corrugated board with arcs. Therefore, when using corrugated board to package products with arcs such as plastic pipes, it is usually only possible to temporarily bend the flat corrugated board to adapt to the shape of the product. Although this temporary bending method can solve the problem temporarily, it will damage the internal structure of the corrugated paper, resulting in damage to the corrugation shape and the adhesion between layers, and thus reducing the overall strength and protection ability of the corrugated board.

[0020] The gluing assembly for placing includes a first receiving plate 101, a second receiving plate 102, a fixed plate 103, a supporting plate 106, a clamping strip 111, a placing plate 112 and a gluing strip 113; the first receiving plate 101 is fixedly connected to the left part of the fixed seat 1; two receiving grooves 10101 are provided on the first receiving plate 101; each receiving groove 10101 is slidably connected with a supporting plate 106; a gluing strip 113 is provided on the right part of each supporting plate 106; the second receiving plate 102 is fixedly connected to the right part of the fixed seat 1; a receiving groove 10101 is provided in the second receiving plate 102; the placing plate 112 is slidably connected in the receiving groove 10101; the fixed plate 103 is fixedly connected to the fixed seat 1; two second sliding grooves 10301 are provided on the fixed plate 103; the second sliding grooves 10301 are I-shaped, and two clamping strips 111 are slidably connected in each second sliding groove 10301.

[0021] The limiting component includes a second movable slider 108 and a second fixed roller 109; two first slide grooves 2001 are provided on the connecting plate 2; each first slide groove 2001 is slidably connected to the second movable slider 108; each second movable slider 108 is provided with a slide groove, and each slide groove is slidably connected to the second fixed roller 109.

[0022] The pressing roller 4 has a built-in electric heating wire, which heats the pressing roller 4 to quickly dry the glue coated on the corrugated core paper 200, thereby accelerating the solidification speed of the glue, so that the corrugated core paper 200 is quickly bonded to the surface paper 100.

[0023] The surface of the curved plate 3 is smooth to prevent the curved plate 3 from damaging the facial paper 100 when the facial paper 100 is fixed on the curved plate 3 to make corrugated paperboard.

[0024] When a factory produces corrugated cardboard, it usually designs arc-shaped cardboard to reduce damage when the flat cardboard 100 bends. Before producing the arc-shaped corrugated cardboard, the support plate 106 in the lower accommodation groove 10101 of the first storage plate 101 slides out to the right, and the placement plate 112 in the accommodation groove 10101 of the second storage plate 102 slides out to the left. The output end of the first driving member 110 moves outward, driving the moving plate 105 fixed thereto and other parts thereon to move backward. At this time, all the pressing rollers 4 are on the same horizontal line, and the two clamping strips 111 of the second chute 10301 are separated from each other.

[0025] During the production process of corrugated cardboard, the pre-bent face paper 100 is placed on the placement plate 112, and its two ends are respectively placed between the two clamping strips 111. At the same time, the corrugated core paper 200 is placed on the support plate 106. During production, first, the first electric slider 10401 drives the connecting plate 2 and the parts thereon to move to directly below the placement plate 112, driving the two clamping strips 111 to move closer to each other to clamp the face paper 100 on the placement plate 112. Subsequently, the placement plate 112 is driven to move into the second storage plate 102, and the clamping strips 111 are driven to move downward along the second chute 10301, driving the face paper 100 to move downward. At the same time, the second moving slider 108 drives the second fixed roller 109 to move along the first chute 2001 in the direction close to the first driving member 110. The face paper 100 is clamped by the clamping strips 111 and driven to move downward until the face paper 100 is initially attached to the arc-shaped plate 3. At this time, the clamping strips 111 release the face paper 100. At the same time, the second moving slider 108 drives the second fixed roller 109 to approach and attach to the face paper 100 attached to the arc-shaped plate 3. When the second fixed roller 109 is about to fix the face paper 100, the clamping strips 111 move upward along the second chute 10301. At this time, the second fixed roller 109 is in contact with the face paper 100. Subsequently, the second fixed roller 109 is driven to move downward along the chute on the second moving slider 108, driving the face paper 100 to move downward until it is completely attached to the arc-shaped plate 3.

[0026] Subsequently, the first electric slider 10401 drives the connecting plate 2 and the parts thereon to move to the lower side of the support plate 106, and the first driving member 110 drives the moving plate 105 to move in the direction close to the support plate 106, driving the pressing rollers 4 to approach the corrugated core paper 200 on the support plate 106, so that the pressing rollers 4 are as Figure 1As shown, at the crests and troughs on the upper and lower sides of the corrugated core paper 200, the support plate 106 located above the first storage plate 101 is driven to move out to the right and cover the corrugated core paper 200. By adjusting the spacing of the pressing rollers 4, the crests and troughs on the corrugated core paper 200 are evenly distributed, avoiding the problem that the crests and troughs of the corrugated core paper 200 inside the corrugated cardboard are unevenly distributed when producing curved corrugated cardboard, resulting in an unstable structure of the curved corrugated cardboard. Subsequently, the glue application strip 113 is driven to apply glue, and the two support plates 106 are moved into the accommodation groove 10101. During the movement, the glue application strip 113 quickly applies glue to the crests and troughs on both sides of the corrugated core paper 200. Compared with the existing method of bonding corrugated cardboard, which can only apply glue to one side where the corrugated core paper 200 is attached to the face paper 100, in the present invention, when the two support plates 106 move into the accommodation groove 10101, the glue application strip 113 quickly applies glue to both sides of the corrugated core paper 200, greatly saving the glue application time.

[0027] After the corrugated core paper 200 is coated with glue, the support plate 106 is also located inside the first storage plate 101. At this time, the pressing rollers 4 are driven to move downward along the moving slide bar 107, and at the same time, the pressing rollers 4 are adjusted to adapt to the curvature of the bending arc plate 3, and the corrugated core paper 200 is adjusted into a curved shape and attached to the face paper 100, as Figure 3 shown. By pressing the glue-coated part of the corrugated core paper 200 with the pressing rollers 4, the troughs of the corrugated core paper 200 are completely attached to the face paper 100. At the same time, the pressing rollers 4 are heated to quickly dry the glue at the crests of the corrugated core paper 200, so that the corrugated core paper 200 is quickly bonded to the face paper 100. Subsequently, the above steps are repeated to attach the face paper 100 to the corrugated core paper 200, and layer by layer stacking is carried out, and finally the production of the curved corrugated cardboard is completed. The production of the curved corrugated cardboard is completed, avoiding the situation in the prior art where curved corrugated cardboard cannot be produced and only flat corrugated cardboard can be temporarily bent, resulting in damage to the internal structure of the corrugated cardboard, damage to the corrugation shape and interlayer bonding, and reduction of the strength and protection ability of the corrugated cardboard.

[0028] Embodiment 2 On the basis of Embodiment 1, as Figure 5 and Figure 6 shown, it further includes a third driving member 204 and a cutting block 205; a third driving member 204 is arranged on the connecting plate 2, and the third driving member 204 is an electric push rod; the output end of the third driving member 204 is rotatably connected to a cutting block 205, and the cutting block 205 is connected to the third driving member 204 through an electric rotating shaft; cutting needles 20501 are arranged on the cutting block 205.

[0029] It further includes a fixed block 201, a second driving member 202 and a second electric slider 203; the fixed block 201 is fixedly connected to the connecting plate 2; a moving groove 20101 is formed on the fixed block 201; the second electric slider 203 is slidably connected to the moving groove 20101; the second electric slider 203 is fixedly connected to the third driving member 204; a plurality of second driving members 202 are fixedly connected to the fixed block 201, and the second driving members 202 are electric push rods; every two second driving members 202 form a group and are respectively located on the upper side, left side and right side of the fixed block 201; the output ends of all the second driving members 202 are fixedly connected to the arc-shaped plate 3.

[0030] The arc-shaped plate 3 is composed of a plurality of bent plates, and each bent plate is detachably connected. The bent plates can be removed to determine the parts of the corrugated paperboard that need to be cut to adapt to the cutting requirements of the corrugated paperboard.

[0031] It includes: A shaping device for processing the base paper into the corrugated core paper 200; A cutting device for cutting the made corrugated core paper 200 and the facing paper 100; A forming device for bending the cut facing paper 100 to a specific arc; A drying and shaping device for applying glue to the peaks and valleys of the corrugated core paper 200 and drying and shaping during the process of bonding the corrugated core paper 200 and the facing paper 100 to form a corrugated paperboard with an arc; The drying and shaping device includes: A placing and gluing assembly, on which the cut corrugated core paper 200 is placed and glued, and at the same time the bent and formed facing paper 100 is placed on the placing and gluing assembly; Convey the bent and formed facing paper 100 to the arc-shaped plate 3 through the placing and gluing assembly and fix the facing paper 100 through the limiting assembly; Fix the corrugated core paper 200 through the positioning assembly, place the corrugated core paper 200 on the facing paper 100 fixed on the arc-shaped plate 3, heat the corrugated core paper 200 through the positioning assembly, dry the glue on the corrugated core paper 200, and at the same time fix the corrugated core paper 200 on the facing paper 100 through the positioning assembly to complete the drying and shaping of the corrugated paperboard.

[0032] When packaging some products with protrusions, such as three-way plastic pipes, since there is a protrusion on the pipe, the corrugated cardboard needs to be temporarily cut with an opening when wrapping the product, so that the pipe with the protrusion can pass through the corrugated cardboard, thus achieving the complete packaging of the product. Therefore, a cutting block 205 and a cutting needle 20501 are provided. After the corrugated cardboard with a curvature is produced, the corrugated cardboard with a curvature is on the bending arc plate 3, and is driven to move towards the corrugated cardboard with a curvature through the output end of the third driving member 204, driving the cutting block 205 and the cutting needle 20501 to move towards the corrugated cardboard with a curvature. After the cutting needle 20501 passes through the corrugated cardboard with a curvature, the output end of the third driving member 204 stops moving. Subsequently, the electric rotating shaft is driven to drive the cutting block 205 to rotate. After the cutting block 205 rotates one circle, it drives the cutting needle 20501 to cut an opening in the corrugated cardboard with a curvature, avoiding the problem that when packaging a pipe with a protruding part, a temporary cut opening is required, and since the corrugated cardboard is in a curved arc shape, directly cutting the corrugated cardboard with a curvature may damage the curved arc shape and structure of the corrugated cardboard.

[0033] Furthermore, in order to meet the diverse requirements of different products for the curvature of the corrugated cardboard, the present invention specifically provides a second driving member 202. Before producing the corrugated cardboard with a curvature, without changing the mold, only the output end of the second driving member 202 is used to drive the bending arc plate 3 to deform, thereby adjusting the bending curvature of the bending arc plate 3. In this way, corrugated cardboard with different curvatures can be produced according to the specific requirements of customers to adapt to various products, ensuring that the corrugated cardboard can closely fit the surface of the product and provide effective protection.

[0034] The above embodiments are only used to illustrate the technical concept and features of the present invention, and their purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
