Description
Technical Field
[0001] This utility model relates to the field of paper laminating machine technology, and in particular to an automatic laminating device for a paper laminating machine. Background Technology
[0002] The laminating device of a paper laminating machine is a device that bonds paper and cardboard together by pressing. Before pressing, the paper is coated with glue. The laminating device uses two rollers to press the paper together, and the glue fixes the paper and cardboard together.
[0003] The utility model patent application publication number CN202322225814.2 belongs to the field of paper laminating machine technology, and in particular, is an automatic laminating device for a paper laminating machine. It includes a pressing roller, with symmetrically distributed limiting connecting rods fixedly connected to both sides of the pressing roller. Elastic telescopic rods are movably connected to the limiting connecting rods, and a fixing rod is fixedly connected to the top of each elastic telescopic rod. A pressure sensing mechanism is fixedly connected between the elastic telescopic rod and the fixing rod, and the pressure sensing mechanism is signal-connected to an external PC. The pressing roller is movably connected to a transmission mechanism through the limiting connecting rods. The limiting connecting rods facilitate connection with the elastic telescopic rods. The elastic telescopic rods undergo elastic deformation, thereby applying a pressing force to the paper. When paperboard of non-standard thickness is present, or when material accumulation occurs, the force on the pressure sensing mechanism differs, and the PC controls the paper laminating machine to pause operation, thus preventing the material accumulation from worsening or the outflow of non-standard products.
[0004] The aforementioned utility model cannot adjust the distance between the device and the drive roller to meet the composite processing requirements of paper of different thicknesses (such as face paper and corrugated cardboard), which increases the limitations of the device. Furthermore, the existing device uses hot melt adhesive, which is squeezed out and eventually sticks to the roller, making the rollers of different thicknesses and difficult to clean, ultimately affecting the quality of another batch of products. Utility Model Content
[0005] The purpose of this utility model is to provide an automatic laminating device for a paper mounting machine to solve at least one of the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic laminating device for a paper mounting machine, comprising an adjusting mechanism, with a heating mechanism at the bottom of the adjusting mechanism; the adjusting mechanism includes a drive assembly and two detection mechanisms; each of the two detection mechanisms includes a limit block, a threaded rod, an adjusting motor, a fixing frame, a bearing, a sliding component, a return spring, a sliding rod, a hollow component, a piezoresistive sensor, and two connecting blocks; the limit block is fixedly connected to the top of the threaded rod, the threaded rod passes through the two connecting blocks, the threaded rod is threadedly connected to the connecting block located at the top, and the threaded rod rotates with the connecting block located at the bottom. The connecting and adjusting motor is fixedly connected to the bottom of the connecting block located at the bottom. The bottom end of the threaded rod is fixedly connected to the output end of the adjusting motor. The two connecting blocks are respectively fixedly connected to the fixed frame and the rear end of the hollow part. The hollow part is placed between the fixed frames and is fixedly connected to the fixed frame. The bottom of the sliding part is fixedly connected to the top of the bearing fixed end. The sliding part passes through the bottom of the hollow part and can slide on the hollow part. The return spring is sleeved on the sliding rod, which passes through the inner wall of the hollow part and can slide on the hollow part. The top end of the return spring is fixedly connected to the hollow part, and the bottom end of the return spring is fixedly connected to the sliding part. The top is fixedly connected, and the piezoresistive sensor is fixedly connected to the inner wall of the hollow component. The piezoresistive sensor is located on the top of the sliding rod. The two detection mechanisms also include connecting plates, which are located between the two hollow components. The two ends of the connecting plates are fixedly connected to the opposite sides of the two hollow components. The two connecting components are fixedly connected to the bottom of the two fixed frames. The hollow roller is located at the bottom of the drive roller, and a flow port is provided between the hollow roller and the drive roller. The paper to be laminated, such as face paper and corrugated cardboard, passes through the flow port between the hollow roller and the drive roller. The initial distance between the two rollers is preset to be slightly larger than the standard paper thickness. If the paper thickness exceeds the preset range, the drive roller is squeezed by the paper and moves upward, driving the drive rod to rise synchronously. The bearings at both ends of the drive rod transmit the displacement to the sliding component. The sliding component slides upward along the inner wall of the hollow component and compresses the return spring. The sliding rod at the top of the sliding component contacts the piezoresistive sensor. The intelligent control panel detects the real-time pressure. The control panel has a built-in pressure threshold. When the real-time pressure exceeds the threshold, the intelligent control panel cuts off the power to the drive motor, and the staff checks the paper jam position. After cleaning, the electrical box is opened through the door panel, and the intelligent control panel starts the drive motor.
[0007] Preferably, the drive assembly includes a drive rod, a drive roller, a kit, a drive motor, a fixing component, and auxiliary components. The drive rod passes through the drive roller and is fixedly connected to it. The left end of the drive rod is fixedly connected to the output end of the drive motor. The kit is fitted onto the drive motor, and the drive motor and the kit are detachably connected. The bottom of the fixing component is fixedly connected to the top of the kit. The fixing component is positioned between the auxiliary components and is threadedly connected to them. Two adjusting motors are electrically connected to the intelligent control panel, a solid-state relay is electrically connected to the intelligent control panel, the drive motor is electrically connected to the intelligent control panel, and a piezoresistive sensor is electrically connected to the intelligent control panel. The auxiliary components are fixedly connected to the hollow component on the left side. The drive rod is positioned between two bearings, and its two ends are fixedly connected to the movable ends of the two bearings, respectively. The operator inputs the target thickness of the paper to be processed on the intelligent control panel. The intelligent control panel drives the threaded rod to rotate by adjusting the motor. The threaded rod engages with the threaded pair of the top connecting block, converting the rotational motion into linear motion, causing the hollow component to slide upward along the guide rail of the fixed frame. The hollow component is rigidly connected to the hollow roller through a connecting component, achieving precise adjustment of the roller spacing.
[0008] Preferably, the heating mechanism includes a heating connector, a hollow roller, a solid-state relay, an intelligent control panel, an electrical box, a door panel, a heating tube, and two connectors. The heating tube is installed inside the hollow roller. The two ends of the hollow roller are rotatably connected to the two connectors respectively.

The right end of the heating tube is connected to the heating connector. The heating connector is fixedly connected to the left side of the electrical box. The solid-state relay and the intelligent control panel are detachably connected to the inner wall of the electrical box. The heating connector is connected to the solid-state relay. The door panel is detachably connected to the electrical box. When production is completed or maintenance is required, the operator activates the heating tube inside the hollow roller by energizing the heating connector through the solid-state relay on the intelligent control panel. The heating element raises the surface temperature of the roller to above the melting point of the hot melt adhesive, softening the adhesive layer. The operator uses a special scraper to move along the roller axis to remove the melted adhesive residue. After cleaning, the system automatically shuts off the heating power and enters standby mode.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. In this utility model, when the paper thickness exceeds the preset range, the drive roller is pressed upward, causing the sliding part to compress the reset spring, triggering the piezoresistive sensor. When the pressure exceeds the threshold, the system automatically cuts off the power to the drive motor and stops the machine. The operator inputs the target paper thickness on the intelligent control panel, and the motor drives the threaded rod to rotate. The rotational motion is converted into linear motion through the threaded pair, causing the hollow part to slide along the guide rail and adjust the distance between the hollow roller and the drive roller. When production ends or maintenance is required, the start panel supplies power to the heating connector through a solid-state relay, activating the heating tube inside the hollow roller to heat up and soften the adhesive layer. After the adhesive residue is removed with a special scraper, the system automatically cuts off the power. Attached Figure Description
