Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, specifically to a decorative panel preparation device. Background Technology

[0002] Hydrogen peroxide foamed gypsum decorative boards, with their lightweight, excellent sound insulation and thermal insulation properties, and environmentally friendly raw materials, have been widely used in architectural decoration scenarios such as residential interior partitions, commercial space ceilings, and high-end interior feature walls. Compared to traditional gypsum boards, hydrogen peroxide foamed gypsum decorative boards utilize the microbubbles generated by the decomposition of hydrogen peroxide to form a porous structure, which not only reduces the weight of the board but also significantly improves its heat insulation and sound absorption capabilities, making it an important development direction for green building decorative materials. However, the unique foaming mechanism of hydrogen peroxide foamed gypsum and the brittle nature of gypsum substrate place stringent requirements on its preparation equipment. Existing decorative panel preparation equipment generally suffers from the following technical defects when adapted to the production of hydrogen peroxide foamed gypsum: First, the temperature control precision is insufficient and the foaming stability is poor. Existing devices mostly use a single electric heating plate to locally heat the mold, which lacks a uniform heat conduction and temperature feedback mechanism, resulting in poor heating effect and thus affecting the molding effect of the decorative board. Second, the demolding mechanism is poorly designed, which makes the sheet material easy to damage. The demolding mechanism of the existing equipment mostly adopts single-cylinder ejection or manual prying: when single-cylinder ejection, the sheet material is subjected to concentrated force, which is prone to "corner cracking"; manual prying can easily cause scratches and deformation on the surface of the sheet material, affecting the appearance of the decorative surface. Although some equipment is equipped with multiple sets of ejector rods, the ejector rods rise and fall asynchronously, resulting in uneven force on the bottom of the sheet material, which is prone to internal micro-cracks and reduces the long-term stability of the sheet material.

[0003] Therefore, it is necessary to redesign and modify the equipment for preparing decorative panels to effectively prevent poor molding results and difficulty in demolding. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a decorative panel preparation device with the advantages of good molding effect and easy demolding.

[0010] As a preferred embodiment of this invention, a temperature detector is provided inside the heating cavity.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model employs a base plate, guide rod, and top plate to form a stable frame. An electric telescopic rod drives a movable plate to slide precisely along the guide rod, allowing the upper forming mold to be placed into the lower forming mold. The first electric heating plate, in conjunction with the second electric heating plate and heat-conducting oil within the heating cavity of the lower forming mold, can uniformly and fully heat the decorative panel material, ensuring the quality of the decorative panel molding.

The lower forming mold 6 includes a forming cavity 10 and a heating cavity 11. Openings 12 are provided at the four corners of the bottom of the inner wall of the forming cavity 10. A support plate 14 is provided below the lower forming mold 6. Top rods 15 are fixedly connected to the four corners of the top of the support plate 14.

A second electric heating plate 13 is fixedly connected to both sides of the inner wall. The heating chamber 11 is filled with heat-conducting oil.

In actual use, a retractable protective sleeve is fitted on the surface of the threaded rod. The retractable protective sleeve can prevent debris from adhering to the surface of the threaded rod.

The contents not described in detail in this specification are the prior art known to those skilled in the art and will not be described in detail in this application.

[0017] refer to Figure 1The drive mechanism includes a slide rail 16 fixedly connected to the top of the base plate 1. Slider 17 is slidably connected to both sides inside the slide rail 16. A connecting rod 18 is hinged to the top of the slider 17. The end of the connecting rod 18 away from the slider 17 is hinged to the bottom of the support plate 14. A threaded rod with positive and negative threads is rotatably connected inside the slide rail 16. The threaded rod with positive and negative threads is threadedly connected to the slider 17. A servo motor 19 is fixedly connected to the right side of the slide rail 16. The output end of the servo motor 19 is fixedly connected to the threaded rod with positive and negative threads.

[0018] As a technical optimization of this utility model, in the drive mechanism, the slide rail 16 provides a stable sliding track for the slider 17. When the servo motor 19 drives the forward and reverse threaded rod to rotate, it can drive the sliders 17 on both sides to move synchronously in opposite directions, thereby pushing the support plate 14 to rise and fall smoothly through the connecting rod 18. This transmission method has high transmission precision, which can ensure that the support plate 14 drives the ejector rod 15 to eject the decorative plate at a uniform speed and stably, avoiding deformation or damage to the decorative plate due to uneven force during the ejection process. At the same time, the stable drive of the servo motor 19 can realize the automated control of the demolding process, reduce human operation errors, improve demolding efficiency, ensure the consistency of each demolding process, and further improve the overall production stability of the device.

[0019] refer to Figure 1 The slide rail 16 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the slide rail 16, while the inner ring of the bearing is fixedly connected to the threaded rod.

[0020] As a technical optimization of this utility model, the bearing fixed inside the slide rail 16 effectively reduces the frictional resistance between the threaded rod and the slide rail 16 during rotation, making the threaded rod rotate more smoothly, reducing wear between components, and extending the service life of the threaded rod and the slide rail 16. The bearing also ensures that the threaded rod maintains stable coaxiality during rotation, preventing uneven movement of the slider 17 due to rotational deviation. This ensures the stability of the connecting rod 18 when pushing the support plate 14 up and down, prevents positional deviation of the ejector rod 15 during demolding, guarantees the demolding quality of the decorative panel, and maintains long-term stable operation of the drive mechanism.

[0021] refer to Figure 1 Both sides of the front and back of the lower forming mold 6 are fixedly connected to sleeves 20. The inside of the sleeves 20 is slidably connected to a limit frame 21. The end of the limit frame 21 away from the sleeves 20 is fixedly connected to the support plate 14.

[0022] As a technical optimization of this utility model, the sleeves 20 on both sides of the front and back of the lower forming mold 6 cooperate with the limiting frame 21 to precisely restrict the movement direction of the support plate 14, so that the support plate 14 can only rise and fall smoothly in the vertical direction, avoiding horizontal deviation of the support plate 14 during the rising and falling process, improving the reliability and safety of the demolding process, and ensuring the overall operational stability of the device.

[0023] refer to Figure 1 The surface of the lower forming mold 6 is provided with a heat insulation layer.

[0024] As a technical optimization of this utility model, the heat insulation layer provided on the surface of the lower molding mold 6 can effectively prevent the heat in the heating cavity 11 from dissipating outward, reduce heat waste, improve the heating efficiency of the heating cavity 11, and reduce energy consumption.

[0025] refer to Figure 2 A temperature detector is installed inside the heating chamber 11.

[0026] As a technical optimization of this utility model, a temperature detector installed inside the heating chamber 11 can monitor the temperature changes within the heating chamber 11 in real time and promptly feed the temperature data back to the PLC controller of the device. Based on the information fed back by the temperature detector, the operator can precisely adjust the working state of the second electric heating plate 13 through the PLC controller to ensure that the temperature inside the heating chamber 11 is always maintained within the optimal range required for the molding of the decorative panel.

[0027] The working principle and usage process of this utility model are as follows: During use, the raw materials required for preparing the decorative panel are evenly placed into the molding cavity 10 of the lower molding mold 6 to ensure uniform distribution and avoid uneven thickness of the decorative panel after molding. Then, the PLC controller of the device is activated, first controlling the second electric heating plate 13 to start working. The second electric heating plate 13 heats the heat-conducting oil in the heating cavity 11, and the heat-conducting oil evenly transfers heat to the molding cavity 10. The temperature detector feeds back the temperature data in the heating cavity 11 to the controller in real time. Based on the feedback information, the operator adjusts the working state of the second electric heating plate 13 through the controller to maintain the temperature in the heating cavity 11 within the optimal range required for the molding of the decorative panel.

[0028] Once the required temperature is reached, the electric telescopic rod 4 is activated by the controller. The output end of the electric telescopic rod 4 drives the movable plate 5 to slide smoothly downward along the guide rod 2. The movable plate 5 drives the fixed plate 7 to move downward synchronously through the connecting rod. The first electric heating plate 8 at the bottom of the fixed plate 7 moves downward together with the fixed plate 7. The upper forming mold 9 at the bottom of the first electric heating plate 8 then enters the forming cavity 10 of the lower forming mold 6, pressurizing the raw material in the forming cavity 10. At the same time, the first electric heating plate 8 releases heat, which, together with the heat transferred by the heat transfer oil, fully and evenly heats the raw material, ensuring that the raw material can be completely formed. The top of the upper forming mold 9 has multiple evenly distributed ventilated micro-holes to maintain the pressure of the electric telescopic rod 4 and the heating state of the electric heating plate for a period of time, allowing the raw material to be formed in the forming cavity 10. During this process, the temperature is continuously monitored by a temperature detector to ensure temperature stability.

[0029] After the raw material is fully formed, the first electric heating plate 8 and the second electric heating plate 13 are turned off by the controller. After the temperature in the forming cavity 10 drops to a suitable demolding range, the upper forming mold 9 is adjusted to move upward, and then the servo motor 19 is started. The output end of the servo motor 19 drives the positive and negative threaded rods in the slide rail 16 to rotate. When the positive and negative threaded rods rotate, they drive the sliders 17 on both sides to move towards each other along the slide rail 16. The sliders 17 drive the hinged connecting rod 18 to push the support plate 14 upward. Under the push of the connecting rod 18, the support plate 14 moves smoothly upward along the limiting direction of the limiting frame 21. The top rod 15 at the top of the support plate 14 slides upward together with the support plate 14. The top rod 15 pushes the formed decorative plate out from the top of the forming cavity 10. After the decorative panel is completely detached from the molding cavity 10, the servo motor 19 is turned off, and the operator removes the ejected decorative panel. Then, the servo motor 19 is restarted to make the positive and negative thread rods rotate in opposite directions, causing the slider 17 to move in the opposite direction. The connecting rod 18 pulls the support plate 14 downward to reset, and the ejector rod 15 returns to its initial position along with the support plate 14. Finally, the molding cavity 10 of the lower molding mold 6 is cleaned to remove residual material debris, and the condition of each component is checked again to prepare for the next use of the device.
