Technical Field

[0001] This utility model relates to the field of paperboard composite equipment technology, and more specifically, to a corrugated paperboard production composite device. Background Technology

[0002] Corrugated board lamination refers to the process of bonding at least one layer of corrugated core paper (commonly known as "corrugated paper") to one or more layers of cardboard (boxboard) using adhesives to form a multi-layer composite material. Due to its unique structure, this material possesses high mechanical strength and excellent cushioning properties, and is widely used in the field of commodity packaging.

[0003] Currently, in the lamination of corrugated cardboard, the rolling motion of the pressure rollers creates downward pressure in localized areas of the cardboard, causing other areas to warp and deform, which can affect the overall product quality.

[0004] To address the aforementioned issues, this application proposes a corrugated cardboard production composite device. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated cardboard production composite device to solve the problem that the pressure rollers in the prior art can easily cause the cardboard to warp and deform.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0011] Preferably, a telescopic support rod is fixed between the slide block and the side of the roller press frame, and an elastic connecting member with equal spacing is fixed between the slide block and the pressure plate. The slide block has a slide track inside, with the opening located on the side close to the roller press frame.

[0012] Preferably, an X-shaped cross plate is provided below the support plate of the roller press frame and between the main roller body. A rotating shaft fixedly connected to the lower surface of the support plate of the roller press frame is rotatably installed at the center of the X-shaped cross plate, and a slider rotatably connected to the slide rail is installed at the end of the X-shaped cross plate.

[0013] Preferably, an electric push rod is fixed on the lower surface of the support plate of the roller press frame, located inside an angle of the X-shaped cross plate, and the movable end of the electric push rod is provided with a push block, one end of which is tapered.

[0014] Preferably, a connecting rod is rotatably mounted on the upper end of the push block, and a support cylinder is rotatably mounted below one end of the connecting rod. The support cylinder and the push block form a clamping space for the rod body of the X-shaped cross plate.

[0015] Preferably, the pressure plate has side plates extending from its left and right ends, and the pressure plate and the side plates have square grooves inside.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] A corrugated cardboard laminating apparatus is provided to improve the quality of cardboard lamination. By setting movable and adjustable secondary pressure rollers 63 on the front and rear sides of the main roller body, and detachably installing rollers 72 at both ends, the secondary pressure rollers 63 can press the cardboard during the main roller pressing operation, thereby avoiding the cardboard warping during the rolling lamination. At the same time, by using four rollers 72 to press against the two sides of the cardboard, the upper cardboard can be clamped and fixed, preventing the problem of skewing caused by the flow of adhesive during the rolling operation.

[0032] In some embodiments, the specific structure of the corrugated cardboard production composite device is as follows: Figure 1-5 As shown, it includes a fixed base 1 and a fixed frame 2 above it;

[0033] Among them, the lower end of the fixed frame 2 is equipped with a movable seat 3 through a screw or ball screw drive, and the lower end of the movable seat 3 is fixedly equipped with a roller pressing frame 4 through a hydraulic lifting mechanism. The main roller body for pressing corrugated cardboard is installed inside the lower end of the roller pressing frame 4.

[0034] Furthermore, positioning units 5 are symmetrically installed on the front and rear sides of the upper surface of the workbench of the fixed base 1. The upper surface of the positioning unit 5 is marked with scales to assist in positioning the corrugated cardboard, and adjacent positioning units 5 can slide close to or away from each other at the same time.

[0035] It should be noted that the movement of the positioning unit 5 can be achieved by a bidirectional ball screw, which is a conventional technical means in this field and will not be described in detail here.

[0036] Please see Figure 2 and Figure 4-5 The roller press frame 4 has symmetrically arranged sliding blocks 61 on the front and rear sides, which are hollow box structures.

[0037] Among them, the slide block 61 has a slide rail 611 on the side near the roller press frame 4;

[0038] Furthermore, an X-shaped cross plate 81 is rotatably mounted on the lower surface of the support plate of the roller press frame 4, and a rotating shaft 811 is rotatably mounted at the intersection center of the X-shaped cross plate 81. The upper end of the rotating shaft 811 is fixedly connected to the roller press frame 4 for suspending and supporting the X-shaped cross plate 81.

[0039] Furthermore, both ends of the two rods of the X-shaped cross plate 81 are rotatably mounted with sliders 812, which are slidably mounted inside the slide rail 611;

[0040] In addition, a plate structure extends upward from the side of the slide block 61 away from the roller press frame 4, and multiple telescopic support rods 65 are fixedly installed between the plate structure and the front and rear sides of the roller press frame 4.

[0041] It is understandable that the X-shaped structure of the X-type cross plate 81, through the sliding connection between the slider 812 and the slide rail 611, can drive the slide block 61 to move closer to or away from the roller press frame 4.

[0042] Among them, an electric push rod 82 is fixedly installed on the lower surface of the support plate of the roller press frame 4, located inside the included angle on one side of the X-shaped cross plate 81;

[0043] Furthermore, a push block 821 is fixedly installed on the movable end of the electric push rod 82, and one end of the push block 821 has a tapered structure, with its tapered surface fitting against the X-shaped cross plate 81;

[0044] It is understandable that the extension movement of the electric push rod 82 can push the X-shaped cross plate 81 through the push block 821 to expand it to the front and rear sides, thereby driving the slide 61 away from the roller press frame 4.

[0045] Among them, a connecting rod 822 is rotatably installed inside the push block 821, and its upper plate is located above the push block 821 and spans the X-shaped cross plate 81. A support cylinder 8221 is rotatably installed below one end of the upper plate of the connecting rod 822.

[0046] It should be noted that the connecting rod 822 and the support cylinder 8221 are symmetrically arranged on both sides of the push block 821;

[0047] It is understandable that the combination of push block 821 and support cylinder 8221 forms a dynamic clamping on a single rod of X-shaped cross plate 81, which can pull the two rods of X-shaped cross plate 81 closer to each other when the electric push rod 82 retracts, thereby driving slide 61 closer to roller frame 4.

[0048] Among them, the slide 61 is equipped with a pressure plate 62 that can move up and down through the elastic connecting parts 64 arranged at equal intervals below. The lower end of the pressure plate 62 is rotatably equipped with a secondary pressure roller 63, and the lower edge of the secondary pressure roller 63 is at the same height as the lower edge of the main body below the roller press frame 4.

[0049] It should be noted that the elastic connector 64 is preferably a spring telescopic rod structure, which is a conventional technical means in this field and will not be described in detail here.

[0050] Please see Figure 2-3 Side plates 621 extend from both the left and right ends of the pressure plate 62. Both the pressure plate 62 and the side plates 621 have square grooves 622 that extend through the front and back directions.

[0051] The side guard unit 7 includes a fixed base 1 and a roller 72;

[0052] The locking post 71 is a square column structure that can be inserted into the inside of the square groove 622. A protruding structure made of elastic silicone rubber is fixedly installed on the outer side of one end of the locking post 71 to hold the locking post 71 against one end of the square groove 622.

[0053] Furthermore, a bracket 712 is fixedly installed at the other end of the locking post 71;

[0054] Furthermore, the roller 72 is divided into upper and lower parts. The upper part is a vertical pole structure, and the lower part is rotatably mounted on the outside of the vertical pole.

[0055] In addition, a movable block 721 is rotatably installed on the outer side of the upper end of the upright, and a spring rod 722 is fixedly installed between the movable block 721 and the bracket 712 to drive the roller 72 closer to the corrugated cardboard.

[0056] It is understandable that after inserting the card post 71 into the inside of the square groove 622, the roller 72 is macroscopically positioned. Then, the spring rod 722 can drive the roller 72 to abut against the two sides of the corrugated cardboard, thereby avoiding the problem of the upper cardboard being skewed due to the flow of the internal adhesive during roll lamination.

[0057] It should be noted that the side baffle units 7 are symmetrically distributed at the left and right ends of the slide 61, and the slide 61 is symmetrically distributed on the front and rear sides of the roller press frame 4. Therefore, the side baffle units 7 symmetrically clamp the corrugated cardboard in four areas, further ensuring the stability of the upper cardboard position.

[0058] Some publicly available information describes the specific usage methods of corrugated cardboard production laminating equipment as follows:

[0059] S1. Under normal conditions, the two rods of the X-shaped cross plate 81 are combined and stored under the support plate of the roller press frame 4. At this time, the auxiliary pressure roller 63 is close to the main roller under the roller press frame 4, which is the minimum distance between the slide 61 and the roller press frame 4.

[0060] S2. Before the roller pressing operation, adjust the distance between the slide block 61 and the roller pressing frame 4 as needed. Through the extension movement of the electric push rod 82, drive the push block 821 to push the X-shaped cross plate 81, so that the combined rods expand in the forward and backward direction, thereby making the slider 812 slide inside the slide rail 611. Then, the telescopic support rod 65 supports the slide block 61, so that the slide block 61 slides away from the roller pressing frame 4 in the forward and backward direction, thereby achieving the effect of expanding the distance.

[0061] Conversely, by retracting the electric push rod 82, the push block 821 and the support cylinder 8221 clamp the X-shaped cross plate 81 rod body, causing the expanded X-shaped cross plate 81 to merge in the opposite direction, thus achieving the effect of reducing the gap.

[0062] S3. Further, adjust the installation position of the side baffle unit 7 according to the size of the corrugated cardboard;

[0063] S4. Insert the locking pin 71 into the inside of the square groove 622, so that the elastic stop 711 passes through the square groove 622 and abuts against the other side surface of the pressure plate 62, thereby coarsely positioning the roller 72.

[0064] S5. The spring rod 722, which is fixedly installed between the bracket 712 and the movable block 721, can drive the roller 72 to approach the corrugated cardboard. Then, the four rollers 72 distributed on the front and rear sides and the two ends of the roller press frame 4 form a symmetrical clamp on the upper corrugated cardboard, so as to keep its position stable and prevent it from shifting during the roller press lamination operation due to the influence of the glue.
