Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Implementation Method 1:

[0036] like Figures 1-5 As shown, an automatic banding machine includes:

[0037] Conveying device for conveying stacked gypsum boards;

[0038] Packaging strip conveying device 4 is located on one side of the conveying device and is used to place and convey packaging strips;

[0039] The packaging strip clamping device 5 is located above the conveying device and is used to clamp one end of the packaging strip and pull it from one side of the conveying device to the other side;

[0040] The material pushing device 7 is lifted and positioned below the conveying device. It rises during material pushing to push the gypsum board.

[0041] The swing arm device 6 is rotatably mounted on the side of the conveying device, which can rotate and press the packaging strips conveyed from the packaging strip conveying device onto the side of the gypsum board.

[0042] Packaging strip pressing devices are installed on both sides of the conveying device to press the packaging strips against the sides of the gypsum board;

[0043] The glue spraying device is installed on the packaging strip conveying device or between the packaging strip conveying device 4 and the packaging strip clamping device 5, and is used to spray glue onto the surface of the packaging strip.

[0044] The conveying device includes a first conveyor 1, a second conveyor 2, and a third conveyor 38 arranged sequentially along the conveying direction of the gypsum board. In a specific embodiment of this application, the first conveyor 1, the second conveyor 2, and the third conveyor 3 are respectively a belt conveyor, a non-powered roller conveyor, and a belt conveyor. After production, the gypsum boards are stacked and enter the first conveyor 1. The packaging strip tray is placed at the packaging strip conveying device 4. The first conveyor 1 conveys the gypsum boards to the synchronous alignment device 3, which aligns the sides of the stacked gypsum boards. The aligned gypsum boards continue to be conveyed by the first conveyor 1 to a position close to the second conveyor 2. When the stacked gypsum boards reach the packaging strip clamping device 5, the packaging strip clamping device 5 pulls the movable end of the packaging strip from one side of the conveyor to the other side. The pushing device 7 rises and pushes the gypsum board to move, and the front side of the gypsum board contacts the packaging strip. As the pushing device 7 continues to push the gypsum board forward, it enters the packaging strip pressing device, which presses the packaging strip against the left and right sides of the gypsum board. When the pushing assembly 7 pushes the gypsum board from the first conveyor 1 through the second conveyor 2 and to the third conveyor 3, the packaging strip is cut, and at this point, the length of the packaging strip is exactly the length that wraps around the gypsum board. After the packaging strip is cut, the swing arm device 6 rotates the packaging strip and presses it onto the back side of the gypsum board, thus completing the gypsum board packaging process. This equipment integrates the alignment of the gypsum board and the application of the packaging strip into one process, reducing manual labor and improving production efficiency. After packaging is completed, the gypsum board is conveyed out by the third conveyor 38 for the next operation.

[0045] One end of the swing arm device 6 is oscillating around a rotating shaft 48 between the conveying device and the packaging strip conveying device 4. A suction cup 46 is fixedly installed on the side of the swing arm device 6 opposite to the conveying device, and the suction cup 46 is used to hold the packaging strip to prevent it from sagging. A transition roller 47 is provided at the movable end of the swing arm device 6, which is used to guide the packaging strip when the pushing device 7 pushes the gypsum board forward. The swing arm device 6 includes a swing arm fixing seat 24, a pushing cylinder 25 is fixedly installed on the swing arm fixing seat 24, a movable frame 26 is fixedly installed at the movable end of the pushing cylinder 25, a second connecting rod 27 is movably installed in the movable frame 26, a swing arm movable seat 28 is fixedly installed on the swing arm fixing seat 24, a swing arm 29 is rotatably installed at the swing arm movable seat 28, and a rotating shaft 48 is fixedly installed at the end of the second connecting rod 27 away from the movable frame 26. The rotating shaft 48 passes through the swing arm movable seat 28 and is fixedly connected to the swing arm 29. The swing arm 29 rotates around the rotating shaft 48.

[0046] The movable end of the cylinder 25 pushes the movable frame 26 to move. During the movement of the movable frame 26, one end of the second connecting rod 27 rotates and moves within the movable frame 26, while the other end of the second connecting rod 27 rotates within the swing arm movable seat 28, causing the swing arm 29 to rotate at the swing arm movable seat 28, thus swinging the swing arm 29. The suction cup 46 is a vacuum suction cup and is fixedly installed on the side of the swing arm opposite to the conveying device. When the packaging strip is wrapped around the side of the gypsum board, the vacuum suction cup is used to prevent the packaging strip from sagging and to adsorb it onto the side wall of the swing arm 11 to prevent the packaging strip from deforming. The transition roller 47 is installed at the end of the swing arm 29. When the pushing device 7 pushes the gypsum board forward, the transition roller 47 contacts the surface of the packaging strip and guides the packaging strip.

[0047] The packaging strip pressing device includes a mounting frame 30 disposed on the outside of the conveying device, a pressing frame 31 disposed on the mounting frame 30, and a plurality of evenly distributed pressing rollers 32 rotatably disposed on the side wall of the pressing frame 31.

[0048] The automatic banding machine also includes a synchronous alignment device 3, which is located at the first conveying device 1. The synchronous alignment device includes two symmetrically arranged mounting seats 9, and a mounting plate 10 is fixedly arranged between the two mounting seats 9. A swing arm 11 is rotatably arranged at the bottom of the mounting plate 10. A first connecting rod 12 is rotatably arranged at both ends of the swing arm 11. A slide block 13 is rotatably arranged at the ends of the two first connecting rods 12 away from the swing arm 11. A guide rail 14 is fixedly arranged between the two mounting seats 9. A slider 15 corresponding to the slide block 13 is slidably arranged on the guide rail 14. The slider 15 is fixedly connected to the slide block 13.

[0049] When the stacked plasterboards are conveyed to the synchronous alignment device 3, the rotation of the swing arm 11 drives the first connecting rod 12 to move, and the first connecting rod 12 drives the slide block 13 to move. As the swing arm 11 rotates continuously, it pulls the slide block 13 to move relative to or away from each other. When the slide block 13 moves relative to each other, it abuts against the side of the plasterboard, realizing the alignment process of the side of the plasterboard. There are two driving methods for the rotation of the swing arm 11. The first is to set a motor at the swing arm 11, and the motor drives the swing arm 11 to rotate to achieve alignment. The second is to set a cylinder at one side of the slide block 13. When the cylinder pushes one side of the slide block 13 to move, it drives the other side of the slide block 13 to move in the same direction or in the opposite direction to achieve alignment. This invention can use either driving method to achieve the same result.

[0050] The packaging strip conveying device 4 includes a base frame 16, on which a packaging strip placement turntable 17 and a packaging strip conveying guide assembly are rotatably mounted. The packaging strip conveying guide assembly includes at least one guide roller and / or two cooperating guide rollers and / or a cooperating guide roller and guide plate. The packaging strip conveying guide assembly is arranged along the packaging strip conveying direction and is located between the packaging strip placement turntable 17 and the conveying device. A baffle plate 45 is also provided on the side of the packaging strip conveying guide assembly near the conveying device. The packaging strip passes through the baffle plate 45. A cutter 44 is provided at the baffle plate 45 to cut the packaging paper that passes through the baffle plate 45.

[0051] The base frame is equipped with at least two packaging strip placement turntables 17 and at least two sets of packaging strip conveying guide assemblies. A sliding guide rail is provided at the bottom of the base frame, which moves along the conveying direction of the conveying device. This packaging strip conveying device can transport packaging strips to designated positions via the sliding guide rail, achieving automatic strip changing. After one roll of packaging strip is used up, it can quickly switch to another roll, improving work efficiency.

[0052] The packaging strip conveying and guiding assembly includes a first guide roller 18 and a second guide roller 19, wherein the second guide roller 19 is located closer to the conveying device, and there is one first guide roller 18. The first guide roller 18 is located closer to the packaging strip placement turntable. The first guide roller 18 can limit and guide the packaging strip wrapped around it from its side. There are two second guide rollers 19, one of which is driven by a cylinder. A baffle plate 45 is provided between the first guide roller 18 and the conveying device. A cutter 44 is provided at the baffle plate 45. The cutter 44 cuts the packaging paper that passes through the baffle plate 45. The packaging strip passes through the baffle plate 45. A cutter baffle is provided on one side of the baffle plate 45. The packaging strip passes through the channel formed by the cutter baffle and the baffle plate 45. The cutter 44 cooperates with the cutter baffle to cut the packaging strip. The disc-shaped packaging strip is placed on the packaging strip placement turntable 17. The movable end of the packaging strip wraps around the first guide roller 18 and passes through the space between two second guide rollers 19 (one of the second guide rollers 19 is connected to a cylinder, which can clamp the packaging strip or open it to allow the packaging strip to pass through. After the packaging strip is cut, the cylinder drives one of the second guide rollers to move, so that the two second guide rollers are pushed by the cylinder to press the packaging strip tightly to prevent the packaging strip from shrinking back) and passes through the channel formed by the cutter baffle and the baffle plate 45. At the channel exit, the end of the packaging strip is clamped by the packaging strip clamping device 5. The packaging strip is guided by the first guide roller 18 and the second guide roller 19. As the packaging strip clamping device 5 clamps the packaging strip and pulls it, it drives the packaging strip placement turntable 17 to rotate to realize the packaging strip feeding process. An optical fiber amplifier is set at the baffle plate 45. When the optical fiber amplifier sensor detects the color mark, the length of the packaging strip is determined by the position of the color mark, and the cutter 44 cuts it, so that the length of the packaging strip is exactly the length that wraps around the plasterboard.

[0053] Preferably, a guide roller or guide plate may be provided between the first guide roller 18 and the second guide roller 19. Specifically, the guide roller and the guide plate may cooperate, or the guide roller and the guide roller may cooperate, and they may be respectively provided between the first guide roller 18 and the second guide roller 19. The cooperation of the first guide roller 18, the guide roller and the guide plate, the cooperation of the guide roller and the guide roller, and the second guide roller 19 form a conveying channel for the packaging strip. The direction of the conveying channel is opposite to the bending direction of the packaging strip.

[0054] The packaging strip clamping device 5 includes a truss 20, one end of which is provided with a drive motor 21. The drive motor 21 is located on the side of the truss 20 away from the packaging strip conveying device 4. A clamping gripper base 23 is movably arranged on the truss 20, and a clamping gripper 23 is fixedly arranged on the clamping gripper base 23. The drive motor 21 drives the clamping gripper base 233 to move along the setting direction of the truss 20, so as to pull the packaging strip from one side of the conveying device to the other side.

[0055] The pushing device 7 includes a pushing base 23, and pressing blocks are respectively provided at both ends of the pushing base 23. The pressing blocks include a first pressing block 34 and a second pressing block 35. When pushing the material, the first pressing block 34 and the second pressing block 35 rise, and the second pressing block 35 translates relative to the first pressing block 34 to achieve alignment and pressing of the gypsum board. After that, the pushing base 23 drives the first pressing block 34 and the second pressing block 35 to translate and push the gypsum board at the conveying device. When the pushing is completed, the first pressing block 34 and the second pressing block 35 fall, and the pushing base 23 drives the pressing blocks to translate in the opposite direction to the pushing direction at the conveying device. The pusher base 23 is movably mounted within the conveying device. A first drive cylinder 36 and a second drive cylinder 37 are mounted on the pusher base 23. Both the first drive cylinder 36 and the second drive cylinder 37 are lifting drive cylinders. The first drive cylinder 36 drives the first pressing block 34 to move vertically up and down, and the second drive cylinder 37 drives the second pressing block 35 to move vertically up and down. A translation drive cylinder is mounted on the second pressing block 35, which drives the second pressing block 35 to move relative to or away from the first pressing block 34. The first pressing block 34 and the second pressing block 35 can move synchronously; that is, when the pusher base 23 translates to push material or returns to the first conveying device 1 after pushing material, it drives the first pressing block 34 and the second pressing block 35 to move synchronously. Alternatively, the first pressing block 34 and the second pressing block 35 can move relative to each other; that is, the translation drive cylinder drives the second pressing block 35 to move horizontally towards the first pressing block 34 to press the gypsum board firmly. When material pushing is required, the first clamping block 34 and the second clamping block 35 rise and the translation drive cylinder pushes the second clamping block 35 to move relative to the first clamping block 34 to clamp the gypsum board. As the base 23 moves to the conveying device, the gypsum board moves to realize the material pushing process. After the material pushing is completed, the translation drive cylinder pushes the second clamping block 34 to move in the opposite direction to the second clamping block 35 and moves to the conveying device. The material pushing device rises-pushes and moves to the conveying device-falls and moves to the conveying device, thus realizing the continuity of the material pushing process.

[0056] When the gypsum board moves between the first conveying device 1 and the second conveying device 2, the first pressing block 34, under the action of the first driving cylinder 36, rises from the bottom of the first conveying device 1 and extends to press and limit the packaging strip on one side of the gypsum board, thereby aligning the sides of the gypsum board. The second pressing block 35, under the action of the second driving cylinder 37, contacts and presses the side of the gypsum board away from the first pressing block 34. A cylinder is fixedly installed at the bottom of the pusher base 33. The cylinder drives the pusher base 33 to move horizontally between the first conveying device 1 and the second conveying device 2. When the gypsum board is conveyed to the front stop device 8, the first pressing block 34 and the second pressing block 35 descend to the bottom under the action of the first driving cylinder 36 and the second driving cylinder 37, and move as the cylinder drives the pusher base 23 to move. During the material pushing process, the first drive cylinder 36 drives the first clamping block 34 to rise vertically, and the second drive cylinder 37 drives the second clamping block 35 to rise vertically. A translational push cylinder then pushes the second clamping block 35 to move horizontally relative to the first clamping block 34, achieving alignment and clamping of the gypsum board. Afterward, the material pushing base 23 drives the first clamping block 34 and the second clamping block 35 to translate and push the gypsum board at the conveying device (i.e., during material pushing, the material pushing device pushes the gypsum board from the first conveying device 1 through the second conveying device). When the material pushing is completed, the first driving cylinder 36 drives the first pressing block 34 to descend, and the second driving cylinder 37 drives the second pressing block 35 to descend. The material pushing base 23 drives the first pressing block 34 and the second pressing block 35 to translate in the opposite direction to the material pushing direction at the conveying device (that is, after the material pushing is completed, the material pushing device moves from the third conveying device 3 to the first conveying device 1). The material pushing device performs the upward-material pushing translation-descending-translation movement, realizing the continuity of the material pushing process.

[0057] The automatic stripping machine also includes a front baffle device 8, which includes a bracket 39. A drive cylinder 40 is fixedly mounted on the bracket 39, and a front baffle 41 is fixedly mounted on the movable end of the drive cylinder 40. The front baffle 41 is vertically adjustable between the conveying device and the bracket 39. The second conveying device 2 conveys the gypsum board to the third conveying device 38. The drive cylinder 40 drives the front baffle 41 to rise and fall at the bracket 39. When it descends and comes into contact with the surface of the third conveying device 38, the front baffle 41 blocks the gypsum board. The glue spraying device includes a glue sprayer and a glue spraying head. The glue spraying head is connected to the glue sprayer. The glue sprayer is located at the conveying device, and the glue spraying head is positioned between the packaging strip conveying device and the conveying device. The glue spraying head sprays a spiral-shaped glue, forming an area. The glue in this area is sprayed in the middle of the entire strip bag. The glue is a pressure-sensitive adhesive. When the packaging strip pressing device applies pressure to it, it makes it stick more firmly. A receiving device is installed below the entire glue spraying mechanism. Since the glue is irregular, some glue will fall down due to gravity during the oblique glue spraying process. The receiving device is used to catch the spilled glue.
