Description

Technical Field

[0001] This utility model relates to the field of paper packaging processing technology, and in particular to a multi-directional automatic laminating device for paper. Background Technology

[0002] In the paper processing industry, lamination is a common surface treatment process used to improve the paper's water resistance, abrasion resistance, and aesthetics. Traditional lamination equipment is mostly designed for small paper rolls. When laminating large-diameter paper rolls (such as paper rolls with a diameter exceeding 1 meter), multiple segmented operations are required, resulting in slow lamination speed, low production efficiency, and difficulty in meeting the needs of mass production. Utility Model Content

[0003] The purpose of this invention is to provide an automatic multi-directional laminating device for raw paper, which has the effect of continuously laminating large-diameter paper tubes in multiple directions.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-directional automatic laminating device for base paper, including a base, a processing frame that slides horizontally on the base, a laminating frame that is rotatably connected to the processing frame, a laminating roller that is fixedly connected to one side of the laminating frame, a film roll that is rotated around the laminating roller, a driving device that drives the laminating frame to rotate is installed on the processing frame, and a steering component that pushes the paper roll to roll is installed on the base.

[0005] By adopting the above technical solution, the paper tube includes a hollow tube body and base paper wound around the hollow tube body. The paper tube to be coated is placed on the base. The paper tube itself has a certain weight. The film at the free end of the film roll is attached to the inner wall of the hollow tube body with adhesive tape. The coating frame is driven to rotate around the paper tube circumferentially by the driving device. The film attached to the paper tube pulls the film roll to rotate on the coating roller to continuously release the film, realizing circumferential coating of the paper tube. Then, the steering component pushes the paper tube forward until the uncoated part of the paper tube is directly opposite the film roll. The coating frame rotates and drives the film on the film roll to continuously wrap around the uncoated part of the paper tube, realizing multi-directional automatic coating of the paper tube, improving the coating speed, and thus improving production efficiency.

[0006] A further feature of this invention is that: a first limiting plate is fixed to the side of the processing frame near the coating roller; the steering assembly includes a limiting cylinder fixedly installed on the base; a second limiting plate is fixed to the output end of the limiting cylinder; the first limiting plate and the second limiting plate are respectively located on both sides of the paper tube; and an adjustment assembly for driving the processing frame to move horizontally is installed on the base.

[0007] By adopting the above technical solution, after the paper tube has been coated once, the adjusting component drives the processing frame and the first limiting plate to move horizontally on the base, so that the first limiting plate is spaced a distance from the paper tube. Then, the output end of the limiting cylinder extends and pushes the paper tube to move closer to the first limiting plate until it abuts against the first limiting plate at the bottom of the paper tube. The first limiting plate and the second limiting plate are located on both sides of the bottom of the paper tube to restrict the movement of the paper tube, so that the uncoated part of the paper tube is facing the film roll. The film roll continuously releases the film and winds it around the outside of the paper tube to perform the coating work, so that the paper tube orientation adjustment is automated, reducing manual intervention and labor intensity.

[0008] A further feature of this invention is that the driving device is a drive motor fixedly mounted on the top of the processing frame.

[0009] By adopting the above technical solution, the output end of the drive motor is connected to the laminating frame to drive the laminating frame to rotate, and the laminating speed is adjustable, thereby achieving efficient laminating work.

[0010] A further feature of this invention is that the adjustment assembly includes recessed grooves disposed on both sides of the base, an adjustment screw is rotatably connected in one recessed groove, and a guide rod is fixedly connected in the other recessed groove. A first slider threaded to the adjustment screw and sliding in the recessed groove is fixed on one side of the processing frame, and a second slider inserted into and sliding on the guide rod is fixed on the other side. An adjustment motor for driving the adjustment screw to rotate is fixedly installed on the base.

[0011] By adopting the above technical solution, when adjusting the direction of the paper tube, the adjusting motor is started to drive the adjusting screw to rotate, thereby the rotation of the adjusting screw drives the first slider, the second slider and the processing frame to move horizontally along the base. Thus, the processing frame and the first limiting plate move to reserve space for the paper tube to roll and turn. The output end of the limiting cylinder extends and pushes the paper tube to rotate towards the first limiting plate until the bottom of the paper tube abuts against the first limiting plate. The winding direction of the film relative to the paper tube is adjusted to achieve multi-directional film coating.

[0012] A further feature of this invention is that the base is fixed with third limiting plates located at both ends of the paper tube, parallel to the adjusting screw, and the first limiting plate, the second limiting plate, and the third limiting plates at both ends together restrict the paper tube from shifting.

[0013] By adopting the above technical solution, when the paper tube rolls and turns, the third limiting plates on both sides restrict the direction of the paper tube roller. At the same time, after the direction of the paper tube is adjusted, the first limiting plate, the second limiting plate and the third limiting plates at both ends work together with the weight of the paper tube to restrict the paper tube from shifting, prevent the paper tube from moving during lamination, and improve the stability of the lamination work.

[0014] A further feature of this invention is that the third limiting plate is vertically fixed with a mounting plate, and the mounting plate is threadedly connected with mounting bolts that extend into the base.

[0015] By adopting the above technical solution, the mounting plate and the third limiting plate are installed on the base by mounting bolts, so that the position of the third limiting plate can be adjusted according to the axial length of the paper tube.

[0016] A further feature of this invention is that the film-coating frame is fixed with a fourth limiting plate and a fixing plate located at the upper and lower ends of the film-coating roller, respectively. The bottom end of the film-coating roller is fixedly connected to the fixing plate. The fourth limiting plate is provided with an insertion hole for the upper end of the film-coating roller to pass through. The lower end surface of the fourth limiting plate is in contact with the upper end surface of the film roll.

[0017] By adopting the above technical solution, during the lamination process, the paper tube rotates and pulls the film roll to continuously rotate relative to the lamination roller to release the film through the already covered film. The fourth limiting plate prevents the film roll from moving up and down during the rotation and film release, thus improving the stability of the lamination process.

[0018] A further feature of this invention is that: adjusting plates are fixed on both sides of the fourth limiting plate, and adjusting bolts that extend into the film-coating frame are threadedly connected to the adjusting plates.

[0019] By adopting the above technical solution, the adjusting plate and the fourth limiting plate can be removed from the laminating frame by adjusting the bolts, thereby removing the used film roll from the laminating roller and replacing it with a new film roll. The fourth limiting plate can move up and down relative to the laminating roller through the insertion hole, so that the bottom end of the fourth limiting plate can be in contact with the top end of the film roll regardless of the size of the film roll, preventing the film roll from moving up and down. At the same time, the fourth limiting plate provides a certain clamping force to the film roll, so that the film released between the paper tube and the film roll has a certain tension, and the film can better cover the paper tube, improving the tightness of the film bonding.

[0020] The beneficial effects of this utility model are as follows: the film at the free end of the film roll is adhered to the inner wall of the hollow cylinder by adhesive tape. The film roll is rotated around the paper roll by the driving device. The film adhered to the paper roll pulls the film roll to rotate on the film rolling roller to continuously release the film, thereby realizing circumferential film covering of the paper roll. Then, the steering component pushes the paper roll forward until the uncovered part of the paper roll is directly opposite the film roll. The film rolling roller rotates and drives the film on the film roll to continuously wrap around the uncovered part of the paper roll, thereby realizing multi-directional automatic film covering of the paper roll, improving the film covering speed, and thus improving production efficiency.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example 1: A multi-directional automatic laminating device for base paper, such as... Figure 1As shown, the system includes a base 1, a processing frame 2 that slides horizontally on the base 1, a laminating frame 3 that is rotatably connected to the processing frame 2, a laminating roller 4 that is fixedly connected to one side of the laminating frame 3, and a film roll 5 that rotates around the laminating roller 4. A drive device for rotating the laminating frame 3 is installed on the processing frame 2. A steering assembly 6 for pushing the paper roll 5 is installed on the base 1. The paper roll includes a hollow cylinder and base paper wound around the outside of the hollow cylinder. The paper roll to be laminated is placed on the base 1. The paper roll itself has a certain weight. The film at the free end of the film roll 5 is adhered to the inner wall of the hollow cylinder using adhesive tape, or to the base paper using low-tack, removable adhesive tape. The drive device then... The moving laminating frame 3 rotates around the paper tube circumferentially. The film adhered to the paper tube pulls the film roll 5 to rotate on the laminating roller 4 to continuously release the film, realizing circumferential lamination of the paper tube (this circumferential lamination direction is from the circular end face of the paper tube as the starting point, along the radial-axial-radial-axial direction of the paper tube to close one or several times with the starting point). Then, the steering component 6 pushes the paper tube forward (during which the laminating frame 3 can stop and wait or continue to rotate and laminate) until the unlaminated part of the paper tube is directly opposite the film roll 5. The rotation of the laminating frame 3 drives the film on the film roll 5 to continuously wrap around the unlaminated part of the paper tube, realizing multi-directional automatic lamination of the paper tube, improving the lamination speed, and thus improving production efficiency.

[0029] like Figure 1 , 3 As shown, a first limiting plate 7 is fixed to the side of the processing frame 2 near the coating roller 4. The steering assembly 6 includes a limiting cylinder 61 fixedly mounted on the base 1. A second limiting plate 62 is fixed to the output end of the limiting cylinder 61. The first limiting plate 7 and the second limiting plate 62 are located on both sides of the paper tube, respectively. An adjusting assembly 8 is installed on the base 1 to drive the processing frame 2 to move horizontally. After the paper tube has completed one round of coating, the adjusting assembly 8 drives the processing frame 2 and the first limiting plate 7 to move horizontally on the base 1, so that there is a certain distance between the first limiting plate 7 and the paper tube. The distance is less than or equal to the width of the film on the film roll 5, so that the adjacent films on the paper roll can be tightly covered. Then, the output end of the limiting cylinder 61 extends and pushes the paper roll to move towards the first limiting plate 7 until it abuts against the first limiting plate 7 at the bottom of the paper roll. The first limiting plate 7 and the second limiting plate 62 are located on both sides of the bottom of the paper roll to restrict the movement of the paper roll, so that the uncoated part of the paper roll is facing the film roll 5. The film roll 5 continuously releases the film and wraps it around the outside of the paper roll to perform the coating work, so that the paper roll orientation adjustment is automated, reducing manual intervention and reducing labor intensity.

[0030] like Figure 2 As shown, the driving device is a drive motor 9 fixedly installed on the top of the processing frame 2. The output end of the drive motor 9 is connected to the laminating frame 3 to drive the laminating frame 3 to rotate. The laminating speed is adjustable. When laminating begins, the speed of the laminating frame 3 can be transitioned from low speed to slightly higher speed. When the laminating work is about to end, the speed of the laminating frame 3 can be transitioned from slightly higher speed to low speed to achieve efficient and stable laminating work.

[0031] like Figure 1 , 3 As shown, the adjustment assembly 8 includes recessed grooves 81 disposed on both sides of the base 1. An adjustment screw 82 is rotatably connected in one recessed groove 81, and a guide rod 83 is fixedly connected in the other recessed groove 81. A first slider 84, threaded to the adjustment screw 82 and sliding in the recessed groove 81, is fixed on one side of the processing frame 2, and a second slider 85, inserted into and sliding on the guide rod 83, is fixed on the other side. An adjustment motor 86, which drives the adjustment screw 82 to rotate, is fixedly installed on the base 1. When adjusting the direction of the paper tube, the adjustment motor 86 is started to drive the adjustment screw 82 to rotate, thereby adjusting the screw. 82 rotates, causing the first slider 84, the second slider 85 and the processing frame 2 to move horizontally along the base 1, thereby moving the processing frame 2 and the first limiting plate 7 to reserve space for the paper tube to roll and turn (during this period, because the paper tube has a certain weight, the paper tube does not move, and when the processing frame 2 drives the film coating frame 3 to move, the paper tube will still pull the film roll 5 to rotate and release the film, but the released film will still be wound on the paper tube later). The output end of the limiting cylinder 61 extends and pushes the paper tube to rotate towards the first limiting plate 7 until the bottom of the paper tube abuts against the first limiting plate 7, adjusting the winding direction of the film relative to the paper tube.

[0032] like Figure 3 As shown, the base 1 is fixed with third limiting plates 10 located at both ends of the paper tube, parallel to the adjusting screw 82. The first limiting plate 7, the second limiting plate 62 and the third limiting plates 10 at both ends together restrict the paper tube from shifting. When the paper tube rolls and turns, the third limiting plates 10 on both sides restrict the direction of the paper tube roller, so that the paper tube can only move in a direction parallel to the moving direction of the processing frame 2. At the same time, after the direction of the paper tube is adjusted, the first limiting plate 7, the second limiting plate 62 and the third limiting plates 10 at both ends, together with the weight of the paper tube, restrict the paper tube from shifting, prevent the paper tube from moving during lamination, and improve the stability of the lamination work.

[0033] like Figure 3 As shown, the third limiting plate 10 is vertically fixed with a mounting plate 11. The mounting plate 11 is threaded with a mounting bolt 12 that extends into the base 1. The mounting plate 11 and the third limiting plate 10 are mounted on the base 1 by the mounting bolt 12, so that the position of the third limiting plate 10 can be adjusted according to the axial length of the paper tube.

[0034] like Figure 2 As shown, the laminating frame 3 is fixed with a fourth limiting plate 13 and a fixing plate 14 located at the upper and lower ends of the laminating roller 4, respectively. The bottom end of the laminating roller 4 is fixedly connected to the fixing plate 14. The fourth limiting plate 13 is provided with an insertion hole 15 for the upper end of the laminating roller 4 to pass through. The lower end face of the fourth limiting plate 13 is in contact with the upper end face of the film roll 5, so that when the laminating is working, the paper tube rotates and pulls the film roll 5 to continuously rotate relative to the laminating roller 4 to release the film through the film that has been covered. The fourth limiting plate 13 prevents the film roll 5 from moving up and down when rotating to release the film.

[0035] like Figure 4 As shown, adjusting plates 16 are fixed on both sides of the fourth limiting plate 13. Adjusting plates 16 are threadedly connected to adjusting bolts 17 that extend into the laminating frame 3. The adjusting plates 16 and the fourth limiting plate 13 can be removed from the laminating frame 3 by adjusting bolts 17, thereby removing the used film roll 5 from the laminating roller 4 and replacing it with a new film roll 5. The fourth limiting plate 13 can move up and down relative to the laminating roller 4 through the insertion hole 15, so that the bottom surface of the fourth limiting plate 13 can be in contact with the upper surface of the film roll 5 regardless of the size of the film roll 5 to prevent the film roll 5 from moving up and down. At the same time, the fourth limiting plate 13 provides a certain clamping force to the film roll 5 (but this clamping force cannot pull the paper tube or cause the film released between the paper tube and the film roll 5 to break when the processing frame 2 and the laminating frame 3 move), so that the film released between the paper tube and the film roll 5 has a certain tension, and the film can better cover the paper tube, improving the tightness of the film material bonding.
