Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box production technology, and in particular to a cardboard paperboard coating feeding and guiding mechanism for cardboard box production. Background Technology
[0002] In the modern packaging industry, cardboard boxes are an indispensable packaging material, widely used in logistics, e-commerce, food, pharmaceuticals and many other fields. To improve the performance of cardboard boxes, such as waterproofing, moisture resistance, wear resistance and aesthetics, lamination technology plays a key role in cardboard box production. By covering the surface of the cardboard with a layer of plastic film, not only can the durability of the cardboard box be enhanced and its service life extended, but the appearance of the cardboard box can also be made more exquisite, improving the overall packaging grade of the product and meeting the diverse packaging needs of different customers.
[0003] The cardboard lamination process in carton production typically includes the following steps: First, the cardboard to be laminated and the lamination roll are placed on the corresponding feeding devices. The cardboard feeding device is responsible for conveying the cardboard to the processing area at a certain speed and in a certain order, while the lamination roll is unfolded by the lamination feeding device so that the film can be conveyed out flat. When the cardboard and the lamination roll arrive at the lamination station, the lamination roll is tightly bonded to the cardboard by heating and pressurizing, thus completing the lamination operation.
[0004] In existing technologies, most feeding and guiding mechanisms lack good adaptability and adjustment capabilities when laminating paperboard of different specifications and types. When dealing with paperboard of different sizes and thicknesses, most guiding mechanisms cannot be flexibly adjusted according to the specific conditions of the paperboard, which can easily lead to positional deviations during the conveying process, thus affecting the accuracy and quality of lamination. Since the specifications and materials of the laminating rolls may vary, existing guiding mechanisms cannot guarantee a good fit between the laminating roll and the paperboard during the conveying process, resulting in increased scrap rates, increased production costs, and reduced production efficiency. Therefore, we urgently need a feeding and guiding mechanism for paperboard lamination in carton production to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problems of lack of adaptability and adjustability of the guiding mechanism in the prior art, and the incompatibility between the lamination and the carton, and to propose a paperboard lamination feeding guiding mechanism for carton production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cardboard laminating and feeding guide mechanism for carton production includes a conveyor belt driven by a drive device and a laminating device installed on the conveyor belt. It also includes: a stand fixedly connected to the middle of the conveyor belt; two sets of sliders slidably connected to the stand; a clamping plate for measuring the width of the laminating roll fixedly connected to one side of each slider near the laminating device; a bracket fixedly connected to the other end of the slider; a guide wheel for positioning the side of the cardboard rotatably connected to the end of the bracket; and a guide roller raised and lowered on the bracket. When the guide roller abuts against a carton on the conveyor belt, a guiding zone is formed.
[0008] In order to allow for the measurement of cardboard dimensions, preferably, a drive motor is fixedly connected to the upright frame, and a bidirectional screw is rotatably connected to the upright frame, with the end of the bidirectional screw fixedly connected to the output end of the drive motor. Two sets of sliders are respectively threadedly connected to the two ends of the bidirectional screw. A guide rod is fixedly connected to the upright frame, and the two sets of sliders are slidably connected to the guide rod. When the drive motor is working, the two sets of sliders move closer to or further away from each other.
[0009] To determine the size of the coated roll, preferably, each of the clamping plates is fixedly installed with a bonding plate. When the two sets of clamping plates approach each other, the bonding plate is bonded to the side of the coated roll.
[0010] In order to position the cardboard, preferably, the end of the bracket is provided with a placement groove, and at least two sets of connecting rods are installed equidistantly in the placement groove along the length of the conveyor belt, and the guide wheel is rotatably connected to the connecting rod. When the brackets on the slider approach each other, the guide wheel abuts against the side of the cardboard.
[0011] In order to guide the cardboard, preferably, an electric push rod is fixedly connected to the support via a connecting frame, and a placement plate is fixedly connected to the output end of the electric push rod. At least two sets of rotating grooves are opened on the placement plate along the length of the conveyor belt, and the end of the guide roller is rotatably connected in the rotating groove. When the electric push rod is working, the placement plate and the guide roller rise or fall.
[0012] To provide friction, the guide roller is preferably made of polyurethane rubber.
[0013] Compared with the prior art, this utility model provides a feeding and guiding mechanism for cardboard lamination in carton production, which has the following advantages:
[0014] 1. The cardboard laminating feeding and guiding mechanism for this carton production uses a drive motor to drive two sets of sliders on a bidirectional screw to move relative to each other. When the clamping plate is in contact with both sides of the laminating roll, the required cardboard size can be determined. When the slider is positioned, the gap between the supports is the required cardboard size, thus avoiding the situation where the cardboard and the laminating roll have size deviations, resulting in poor processing efficiency.
[0015] 2. This cardboard laminating feeding and guiding mechanism for carton production, through the setting of guide wheels and guide rollers, allows two sets of sliders to be positioned when the clamping plate determines the size of the laminating roll. The gap between the two sets of supports and the required cardboard position are determined. The operator only needs to place the cardboard on the conveyor belt, and the conveyor belt will move the cardboard. The two sides of the cardboard will contact the guide wheels, thereby achieving the alignment of the cardboard. With the action of the electric push rod, the guide roller is brought into contact with the surface of the cardboard. While guiding, it also provides leveling of the cardboard, thus avoiding the situation where the cardboard and the laminating roll are mismatched. It also improves the adaptability and adjustability of the guiding mechanism.
[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model effectively improves the adaptability and adjustability of the guiding mechanism, avoids dimensional deviations between the film and the cardboard, and thus improves production efficiency.

[0024] Example:
[0025] Reference Figures 1-4 A cardboard laminating and feeding guide mechanism for carton production includes a conveyor belt 1 driven by a drive device and a laminating device 2 mounted on the conveyor belt 1. The conveyor belt 1, driven by the drive device, moves the cardboard to the laminating device 2 for the laminating process. During processing, the laminating roll is mounted on the laminating device 2, and lamination is performed as the cardboard passes through the laminating device 2. The mechanism also includes: a stand 3 fixedly connected to the middle of the conveyor belt 1; two sets of sliders 4 slidably connected to the stand 3; a clamping plate 5 for measuring the width of the laminating roll fixedly connected to the side of the sliders 4 closest to the laminating device 2; a drive motor 9 fixedly connected to the stand 3; and a bidirectional screw 10 rotatably connected to the stand 3. The end of the screw 10 is fixedly connected to the output end of the drive motor 9. Two sets of sliders 4 are threadedly connected to the two ends of the bidirectional screw 10. A guide rod 11 is fixedly connected to the upright 3. The two sets of sliders 4 are slidably connected to the guide rod 11. When the drive motor 9 works, the two sets of sliders 4 move closer or further away from each other. A bonding plate 17 is fixedly installed on each clamping plate 5. When the two sets of clamping plates 5 move closer to each other, the bonding plate 17 is bonded to the side of the laminated roll. Here, the drive motor 9 drives the two sets of sliders 4 on the bidirectional screw 10 to move relative to each other. When the clamping plate 5 is bonded to both sides of the laminated roll, the required cardboard size can be determined, avoiding the situation where the cardboard and the laminated roll have a size deviation, resulting in poor processing efficiency.
[0026] A bracket 6 is fixedly connected to the other end of the slider 4. A guide wheel 7 for positioning the side of the cardboard is rotatably connected to the end of the bracket 6. A guide roller 8 is also mounted on the bracket 6. The guide roller 8 is made of polyurethane rubber. Here, the polyurethane rubber has sufficient friction to move the cardboard while maintaining a smooth surface, preventing scratches. It has excellent wear resistance, a long service life, and good elasticity, adapting to slight unevenness in the cardboard. When the guide roller 8 abuts against the carton on the conveyor belt 1, a guiding area is formed. A placement groove 12 is provided at the end of the bracket 6, and at least two sets of connecting rods 13 are equidistantly installed in the placement groove 12 along the length of the conveyor belt 1. The guide wheel 7 is rotatably connected to the connecting rod 13. When the brackets 6 on the slider 4 approach each other, the guide wheel 7 abuts against the side of the cardboard. An electric push rod 14 is fixedly connected to the bracket 6 via a connecting frame. A placement plate 15 is fixedly connected to the output end of the electric push rod 14. At least two sets of rotating grooves 16 are provided on the placement plate 15 along the length of the conveyor belt 1, and the end of the guide roller 8 is rotatably connected to... Inside the rotating slot 16, when the electric push rod 14 is working, the placement plate 15 and guide roller 8 rise or fall. Here, when the clamping plate 5 determines the size of the laminating roll, the two sets of sliders 4 are positioned, and the gap between the two sets of brackets 6 and the required cardboard position are determined. The operator only needs to place the cardboard on the conveyor belt 1, and the cardboard will move through the cooperation of the conveyor belt 1. The two sides of the cardboard will contact the guide wheels 7, thereby achieving the alignment of the cardboard. With the cooperation of the electric push rod 14, the guide roller 8 is brought into contact with the surface of the cardboard. While guiding, it also provides leveling of the cardboard, thereby avoiding the situation where the cardboard and the laminating roll size are not compatible, and improving the adaptability and adjustability of the guiding mechanism.
[0027] In this invention, after the operator installs the laminating roll onto the laminating equipment 2, the operator starts the drive motor 9. The drive motor 9 drives the bidirectional screw 10 to rotate, causing the two sliders 4 to move closer to each other. When the bonding plate 17 on the clamping plate 5 contacts both sides of the laminating roll, the drive motor 9 stops running, positioning the sliders 4. Due to the positioning of the sliders 4, the gap between the supports 6 on the sliders 4 and the size of the cardboard that can be processed are determined. At this time, the operator can place the cardboard sequentially on the conveyor belt 1. Driven by the conveyor belt 1, the cardboard moves. When the cardboard contacts the guide wheel 7, it will be aligned under the action of the guide wheel 7. The electric push rod 14 drives the placement plate 15 to move downward, so that the guide roller 8 abuts against the surface of the cardboard. Driven by the conveyor belt 1, the cardboard enters the laminating equipment 2 along the guide path for lamination.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
