Description

Technical Field

[0001] This utility model relates to the field of composite paper pressing technology, specifically to a composite paper pressing device. Background Technology

[0002] Composite paper is a type of processed paper made by laminating paper, paperboard and other materials (such as plastic, aluminum foil, cloth, etc.) together using adhesives. This material not only improves the appearance and strength of paper and paperboard, but more importantly, it enhances their properties such as water resistance, moisture resistance, oil resistance, air tightness and aroma retention. In addition, composite paper can also achieve properties such as heat sealing, light blocking and heat resistance. A pressing device is required during the processing of composite paper.

[0003] Traditional lamination devices lack reliable positioning mechanisms, which can easily lead to misalignment or wrinkles in multi-layered materials during lamination. This results in uneven edges of the composite paper and uneven interlayer adhesion, affecting product quality. The lamination force cannot be precisely controlled; excessive pressure can cause thin materials to crack, while insufficient pressure results in weak interlayer adhesion. Furthermore, the pressure is applied as a rigid impact without a buffer mechanism, further increasing the risk of material breakage. To address these issues, a lamination device for composite paper is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a composite paper pressing device, which solves the problems of existing traditional pressing devices lacking a reliable positioning mechanism, causing misalignment or wrinkles in multi-layered materials during pressing, resulting in uneven edges and uneven interlayer adhesion of the composite paper, affecting product quality, and the inability to accurately control the pressing force. Excessive pressure can easily cause thin materials to crack, while insufficient pressure results in weak interlayer adhesion. Furthermore, the pressure is applied as a rigid impact without a buffer mechanism, further increasing the risk of material damage.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a composite paper pressing device, including an operating table, with guide rods fixedly connected at the four corners of the upper surface of the operating table, pressing components installed above the four guide rods, movable guide rails fixedly connected on the left and right sides of the upper surface of the operating table, and a pressing platform slidably connected above the two sets of movable guide rails via sliding blocks, with several positioning holes opened on the left rear side of the upper surface of the pressing platform, and right-angle positioning blocks detachably connected above the pressing platform via the positioning holes, and two sets of positioning columns fixedly connected to the rear side of the pressing platform on the upper surface of the operating table.

[0006] Preferably, an installation groove is provided in the middle of the upper surface of the operating table, and an electric telescopic rod is fixedly connected inside the installation groove. The output end of the electric telescopic rod is fixedly connected to the rear side of the bottom surface of the pressing table through a connector.

[0007] Preferably, a timer is provided on the left side of the front side of the operating table, a force display is fixedly installed on the right side of the timer on the front side of the operating table, and a pressure switch is provided on the right side of the force display on the front side of the operating table.

[0008] Preferably, a start button is provided on the right side of the control panel, and an emergency stop button is fixedly installed on the front side of the control panel above the start button.

[0009] Preferably, the pressing assembly includes a fixing plate, which is fixedly connected above four guide rods. A lifting cylinder is fixedly connected to the upper center of the fixing plate, and an air source component is fixedly connected to the rear side of the upper surface of the fixing plate. The air source component is connected to the air inlet end of the lifting cylinder through a pipeline.

[0010] Preferably, the output end of the lifting cylinder passes through the bottom surface of the fixed plate and is fixedly connected to a movable plate. Guide sleeves are fixedly connected at the four corners of the movable plate, and the four guide sleeves are slidably connected to four guide rods respectively.

[0011] Preferably, the pressing assembly further includes a lower pressure plate, an anti-slip pad is fixedly connected to the bottom surface of the lower pressure plate, a pressure sensor is fixedly connected to the middle of the upper surface of the lower pressure plate, guide rods are fixedly connected to the four corners of the upper surface of the lower pressure plate, the four guide rods are slidably connected to the moving plate, and a prestressed spring is sleeved on the outer surface of each of the four guide rods. The upper end of the prestressed spring is fixedly connected to the bottom surface of the moving plate, and the lower end of the prestressed spring is fixedly connected to the top of the lower pressure plate.

[0012] Compared with the prior art, the advantages of this utility model are: 1. The pressing table of this utility model forms a "left-back" bidirectional positioning boundary by cooperating with the positioning column through the right-angle positioning block (the position can be adjusted through the positioning hole), ensuring that the placement deviation of the composite paper is ≤0.5mm, effectively avoiding interlayer offset or wrinkles, and improving the product qualification rate by more than 20% compared with the traditional product without positioning device. The pressing table moves smoothly in and out along the moving guide rail, and is driven by the electric telescopic rod to reduce the positioning error caused by manual pushing and pulling, further ensuring the positional stability of the composite paper during the pressing process.

[0013] 2. This utility model monitors the pressing force in real time through a pressure sensor and provides intuitive feedback through a force display. With the help of a pressure switch, the pressing pressure can be preset to ensure that the pressure is accurately matched to different materials, avoiding damage from overpressure or delamination from underpressure. The prestressed spring enables flexible application of pressure: in the initial stage, the material is initially pressed by the spring preload, and the pressure gradually increases as the moving plate descends, avoiding material breakage caused by rigid impact. It is especially suitable for brittle or thin composite materials and reduces the breakage rate of finished products. Attached Figure Description

Right-angle positioning blocks 9 are detachably connected to the pressing table 5 via the positioning holes 8. Two sets of positioning posts 10 are fixedly connected to the upper surface of the operating table 1 on the rear side of the pressing table 5. The guide rods 2 ensure the verticality of the pressing components 3 when they are raised and lowered. The moving guide rails 4 ensure the smooth movement of the pressing table 5. The cooperation between the positioning holes 8 and the right-angle positioning blocks 9 enables the rapid positioning of composite papers of different sizes. The positioning posts 10 further improve the reset accuracy of the pressing table 5. The overall structure provides a stable foundation and accurate positioning guarantee for the pressing of composite paper.

[0019] Specifically, an installation groove 6 is provided in the middle of the upper surface of the operating table 1. An electric telescopic rod 7 is fixedly connected inside the installation groove 6. The output end of the electric telescopic rod 7 is fixedly connected to the rear side of the bottom surface of the pressing table 5 through a connector. The electric telescopic rod 7 can stably drive the pressing table 5 to slide back and forth along the moving guide rail 4, realizing the precise switching between the material picking and placing position outside the pressing component 3 and the pressing position directly below.

[0023] Specifically, the output end of the lifting cylinder 302 passes through the bottom surface of the fixed plate 301 and is fixedly connected to the moving plate 304. Guide sleeves 305 are fixedly connected at the four corners of the moving plate 304. The four guide sleeves 305 are slidably connected to the four guide rods 2 respectively. The cooperation between the guide sleeves 305 and the guide rods 2 provides precise guidance for the lifting of the moving plate 304, ensuring that the moving plate 304 moves smoothly in the vertical direction, avoiding skewing during the pressing process, and ensuring that the lower pressure plate 306 applies uniform pressure to the composite paper.

[0024] Furthermore, the pressing assembly 3 also includes a lower pressing plate 306. An anti-slip pad 307 is fixedly connected to the bottom surface of the lower pressing plate 306. A pressure sensor 308 is fixedly connected to the center of the upper surface of the lower pressing plate 306. The pressure sensor 308 can be of model EVT-12C-SJTT.

[0025] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The specific implementation of this disclosure omits detailed descriptions of known functions and components. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of commercially available instruments. In addition, the air source, pipelines, and control system required for the cylinder are common knowledge known to those skilled in the art and will not be elaborated on here.

[0026] Working principle: Based on the size of the composite paper, select the appropriate positioning hole 8 on the pressing table 5, install the right-angle positioning block 9, set the pressing pressure through the pressure switch 13, set the pressing duration through the timer 11, ensure the air supply pressure of the lifting cylinder 302 is stable through the air source component 303, start the electric telescopic rod 7, its output end pulls the pressing table 5 to slide forward along the moving guide rail 4, extending to the outside of the pressing assembly 3, place the composite paper to be pressed (already coated with glue) on the pressing table 5, so that the left edge and rear edge of the composite paper are respectively attached to the two sides of the right-angle positioning block 9, and complete the positioning. The electric telescopic rod 7 extends, driving the pressing table 5 back to directly below the pressing assembly 3. At this time, the composite paper is directly below the lower pressure plate 306. The positioning column 10 helps to confirm that the position of the pressing table 5 is correct. Press the start button 14, the air source component 303 supplies air to the lifting cylinder 302, the cylinder output end pushes the moving plate 304 to slide downward along the guide rod 2, and the moving plate 304 slides downward. During descent, the lower pressure plate 306 first contacts the surface of the composite paper. At this time, the prestressed spring 310 provides a certain degree of prestress to press the composite paper first. As the moving plate 304 continues to descend, the prestressed spring 310 will gradually compress until the bottom surface of the moving plate 304 abuts against the upper surface of the pressure sensor 308. The moving plate 304 transmits the force to the lower pressure plate 306 through the pressure sensor 308 to press the composite paper. The pressure sensor 308 detects the pressing force in real time and transmits the data to the force display 12. When the pressure reaches the preset value, the lifting cylinder 302 stops descending and maintains the pressure. The timer 11 starts timing to ensure that the adhesive between the composite paper layers is fully cured. If the pressure fluctuates during this period, the lifting cylinder 302 automatically replenishes or vents air for fine adjustment. After the timing ends, the lifting cylinder 302 drives the moving plate 304 to rise, the lower pressure plate 306 disengages from the composite paper, and the prestressed spring 310 returns to its original length.
