Description

Technical Field

[0001] This utility model belongs to the field of extruded board processing technology, and in particular, it is a device for online embossing on the surface of extruded board. Background Technology

[0002] Extruded polystyrene (XPS) boards are materials formed by continuous extrusion foaming using a special process. During the production of XPS boards, embossing equipment is required for embossing. Existing embossing equipment uses modular extrusion molding, which involves feeding, extrusion, and unloading. However, current embossing devices lack heating capabilities and are directly exposed to the outdoor environment, affecting the embossing effect.

[0003] A search revealed a Chinese patent document (authorization announcement number CN217531872U) entitled "An Embossing Device for Extruded Polystyrene (XPS) Boards." This device includes a horizontally mounted frame with a conveyor belt. A rotatable embossing roller is positioned above the conveyor belt. Multiple protruding pressing blocks are evenly spaced on the outer surface of the embossing roller. Shaft seats are symmetrically located on both sides of the top of the mounting frame. The embossing roller is rotatably mounted on the two shaft seats. Multiple feeding components are radially distributed outwards from the shaft. This invention utilizes a cooperating conveyor belt, shaft seats, and embossing roller. The conveyor belt continuously supplies XPS boards to the embossing roller, and the rotating embossing roller presses the moving XPS boards, thus enabling continuous embossing of the XPS boards and solving the problem of existing embossing equipment being unable to continuously emboss XPS boards. However, the embossing device described in this patent lacks heating capabilities and is directly exposed to the outdoor environment, which may affect the embossing effect. Utility Model Content

[0004] The purpose of this invention is to provide an online embossing device for the surface of extruded polystyrene boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an online embossing device for the surface of extruded polystyrene (XPS) boards, comprising:

[0006] Insulation frame;

[0007] The adjustment component is embedded in the top of the insulation frame. The bottom of the adjustment component is connected to the upper lifting lug. The inner wall of the upper lifting lug is rotatably connected to the embossing roller for online embossing of the surface of the extruded board and the limiting roller for limiting position via a rotating shaft.

[0008] Multiple lower lifting lugs are fixedly connected to the top of the insulation frame. The inner walls of the multiple lower lifting lugs are rotatably connected to conveyor rollers via rotating shafts. The outer circumferences of the multiple conveyor rollers are driven by a conveyor belt for conveying the extruded board.

[0009] The heating box is installed on top of the insulation frame. The inner wall of the heating box is equipped with a heat-resistant fan and multiple heating tubes. The heating box is connected to the insulation frame through multiple vent pipes. The inner wall of the insulation frame is equipped with multiple temperature sensors.

[0010] As a preferred embodiment, the regulating component includes:

[0011] Vertical electric actuator, embedded in the top of the insulation frame;

[0012] An adjusting plate is fixedly connected to the bottom end of the moving part of the vertical electric actuator. A hollow plate is sleeved around the outer periphery of the adjusting plate, and the hollow plate is connected and fixed to the upper lifting lug.

[0013] As a preferred embodiment, a pressure sensor is installed at the bottom of the adjustment plate, and a spring connects the measuring part of the pressure sensor to the upper lifting lug.

[0014] As a preferred embodiment, a speed-regulating motor that provides power to the rotating shaft is installed on the outer periphery of both the upper lifting lug and one of the lower lifting lugs, and the two speed-regulating motors rotate at the same speed.

[0015] As a preferred embodiment, multiple limiting frames are embedded in the top of the insulation frame, and the inner cavity of the limiting frames is provided with partition plates for separating the space.

[0016] As a preferred embodiment, the side of the limiting frame is provided with a threaded channel, and the threaded channel is threadedly connected to a clamping threaded rod for fixing the partition plate.

[0017] As a preferred embodiment, the inner wall of the insulation frame is equipped with multiple cameras for recording.

[0018] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0019] First, the device can accurately ensure the embossing quality of extruded polystyrene (XPS) boards, meeting diverse processing needs. A heat-resistant fan inside the heating chamber, working in conjunction with multiple heating tubes, delivers hot air into the insulation frame through a vent pipe. Simultaneously, a temperature sensor on the inner wall of the insulation frame monitors the internal temperature in real time, ensuring the XPS board is embossed within a suitable temperature environment, preventing embossing effects caused by improper temperature. Multiple limiting frames embedded at the top of the insulation frame contain partitions. By adjusting the position of these partitions within the limiting frames, a suitable processing space can be created according to the width of the XPS board, effectively limiting the board's movement and preventing it from shifting during processing, thus reducing energy loss. The threaded channels on the sides of the limiting frames connect to threaded rods that secure the partitions after their positions are determined, ensuring stable positioning.

[0020] Secondly, the equipment boasts excellent operational flexibility, adapting to the processing of extruded polystyrene (XPS) boards of different specifications. The vertical electric actuator in the adjustment assembly moves the adjustment plate, thereby adjusting the height of the upper lifting lugs and embossing rollers. Combined with pressure sensors monitoring the embossing pressure, it can precisely control the embossing force, resulting in uniform and clear embossing on the XPS board surface, significantly improving product quality. The speed-regulating motors on the outer periphery of the upper and lower lifting lugs can synchronously adjust their rotation speed, thereby controlling the running speed of the embossing rollers and conveyor rollers. This allows it to match the processing rhythm of XPS boards of different thicknesses and adjust processing efficiency according to production needs, greatly enhancing the equipment's applicability.

[0021] The online embossing device for the surface of extruded polystyrene board can perform heating and heat preservation to ensure the temperature of the embossing environment. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0032] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0033] The connection method can adopt existing methods such as bonding, welding, and bolting, depending on the actual needs. Techniques, methods and equipment known to those skilled in the art may not be discussed in detail. However, where appropriate, the techniques, methods and equipment should be regarded as part of the specification. The proportions of the components in the drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0034] Please see Figures 1 to 4 As shown, an online embossing device for the surface of extruded polystyrene (XPS) board is provided in this embodiment, which includes:

[0035] Insulation frame 1;

[0036] Adjustment component 2 is embedded in the top of insulation frame 1. The bottom end of adjustment component 2 is connected to upper lifting lug 3. The inner wall of upper lifting lug 3 is rotatably connected to embossing roller 18 for online embossing of the surface of extruded board and limiting roller 4 for limiting position via rotating shaft. A laser thickness gauge is set and installed on the discharge side of embossing roller 18 to detect the actual texture depth of board after embossing in real time.

[0037] Multiple lower lifting lugs 5 are fixedly connected to the top of the insulation frame 1. The inner walls of the multiple lower lifting lugs 5 are rotatably connected to conveyor rollers 6 via rotating shafts. The outer periphery of the multiple conveyor rollers 6 is driven by a conveyor belt 7 for conveying the extruded board.

[0038] A heating chamber 8 is installed at the top of the insulation frame 1. A heat-resistant fan 9 and multiple heating tubes 10 are installed on the inner wall of the heating chamber 8. The heating chamber 8 is connected to the insulation frame 1 through multiple ventilation pipes 11, with a flow guide structure installed at each ventilation pipe 11 to ensure uniform preheating and heating of the extruded polystyrene board. Multiple temperature sensors 12 are installed on the inner wall of the insulation frame 1. Multiple heating tubes 10 are preheated to begin heating, and the heat-resistant fan 9 is simultaneously activated. The heat-resistant fan 9 delivers hot air from the heating chamber 8 to the interior of the insulation frame 1 through the ventilation pipes 11, heating the extruded polystyrene board to be embossed within the insulation frame 1 and improving its plasticity. The multiple temperature sensors 12 installed on the inner wall of the insulation frame 1 monitor the temperature inside the insulation frame 1 in real time. When the temperature reaches the preset suitable embossing temperature (set according to the material of the extruded polystyrene board), the temperature sensors 12 provide feedback signals, allowing for appropriate adjustment of the power and number of heating tubes 10 to maintain a stable temperature inside the insulation frame 1.

[0039] Adjustment component 2 includes:

[0040] A vertical electric actuator 21 is embedded in the top of the insulation frame 1;

[0041] An adjusting plate 22 is fixedly connected to the bottom end of the moving part of the vertical electric push rod 21. A hollow plate 23 is sleeved around the outer periphery of the adjusting plate 22. The hollow plate 23 is fixedly connected to the upper lifting lug 3. A pressure sensor 24 is installed at the bottom end of the adjusting plate 22. A spring 25 is connected between the measuring part of the pressure sensor 24 and the upper lifting lug 3. When the vertical electric push rod 21 (embedded in the top of the insulation frame 1) is started, the moving part of the vertical electric push rod 21 drives the fixedly connected adjusting plate 22 to move. The adjusting plate 22 slides in the hollow plate 23. At the same time, the pressure sensor 24 installed at the bottom end of the adjusting plate 22 monitors the pressure change of the spring 25 between the adjusting plate 22 and the upper lifting lug 3 in real time. When the pressure detected by the pressure sensor 24 reaches the preset value (corresponding to the required embossing depth), the vertical electric push rod 21 stops running. At this time, the height position of the embossing roller 18 is fixed, and the embossing conditions are met.

[0042] Both the upper lifting lug 3 and one of the lower lifting lugs 5 are equipped with speed-regulating motors 13 that provide power to the rotating shaft. The two speed-regulating motors 13 have the same speed. When the speed-regulating motor 13 installed on the outer periphery of the upper lifting lug 3 (with the same speed as the speed-regulating motor 13 at the lower lifting lug 5) is started, the motor drives the embossing roller 18 connected to the inner wall of the upper lifting lug 3 through the rotating shaft to rotate. As the extruded board is continuously conveyed to the area below the embossing roller 18 by the conveyor belt 7, the rotating embossing roller 18 performs online embossing on the heated surface of the extruded board to form a preset pattern.

[0043] The two speed-regulating motors 13 can also be replaced with a single motor linkage structure for synchronous transmission, and can adapt to the adjustment of the vertical electric actuator 21. A precision planetary reducer is added between the speed-regulating motor 13 and the rotating shaft to reduce the output speed and increase the torque, while buffering impact loads. High-hardness bearings (such as high-chromium iron material) are selected to improve the bearing's wear resistance and service life.

[0044] To reduce heat loss, multiple limiting frames 14 are embedded in the top of the insulation frame 1. The inner cavity of the limiting frame 14 is provided with a partition plate 15 for separating the space. The side of the limiting frame 14 has a threaded channel, and the threaded channel is threadedly connected to a clamping threaded rod 16 for fixing the partition plate 15. After loosening the clamping threaded rod 16 in the threaded channel on the side of the limiting frame 14 and moving the partition plate 15 to a suitable position, the clamping threaded rod 16 is tightened to fix the partition plate 15, thereby reducing heat loss. Multiple cameras 17 for recording are installed on the inner wall of the insulation frame 1.

[0045] All structures in this application undergo regular cleaning and maintenance to ensure cleanliness and safe use. Furthermore, since they operate in heated environments, all structures and instruments undergo heat-resistant treatment to ensure safe use.

[0046] Build an intelligent monitoring and early warning platform:

[0047] Expanded monitoring parameters: Added roller temperature sensor (to monitor embossing roller temperature), motor current sensor (to monitor load fluctuations), and vibration sensor (to monitor equipment operating stability).

[0048] AI visual inspection is introduced: using images captured by camera 17, deep learning algorithms are used to identify defects such as blurred textures, misalignment, and incompleteness in real time. Once the standard is exceeded, an audible and visual alarm is triggered and the equipment is suspended.

[0049] Data visualization: Integrate all monitoring data into the touch screen to generate equipment operation curves and production reports, providing data support for process optimization.

[0050] The heat-resistant fan 9, heating tube 10, temperature sensor 12, speed-regulating motor 13, camera 17, vertical electric actuator 21, and pressure sensor 24 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. In order to facilitate the inspection, maintenance, and parts replacement of the device, the parts inside a single device are usually from the same manufacturer and of the same model, function, and batch. Therefore, even if there is a certain difference between two or more electrical control devices, the synchronous movement of the electrical control devices can still be maintained under the action of the controller. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this utility model.

[0051] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology.

[0052] Working principle

[0053] Device initialization and preparation for extruded board positioning

[0054] Adjust the position of the partition plate 15 according to the size of the extruded board: loosen the threaded rod 16 in the threaded channel on the side of the limit frame 14, move the partition plate 15 to the appropriate position, and then tighten the threaded rod 16 to fix the partition plate 15, thereby reducing heat dissipation.

[0055] XPS board conveyor start

[0056] Start the speed-regulating motor 13 installed on the outer periphery of the lower lifting lug 5. The motor drives the conveyor roller 6 connected to the inner wall of the lower lifting lug 5 through the rotating shaft to rotate. When multiple conveyor rollers 6 rotate synchronously, the conveyor belt 7 that drives the outer periphery together starts to run.

[0057] The extruded polystyrene board to be embossed is placed at the input end of the conveyor belt 7. Driven by the conveyor belt 7, the extruded polystyrene board is conveyed along the limiting space formed by the partition plate 15 in the limiting frame 14 towards the embossing roller 18 and the limiting roller 4. At this time, the limiting roller 4 can initially limit the vertical movement of the extruded polystyrene board to prevent it from moving up and down during conveying.

[0058] Embossing pressure adjustment and embossing preparation

[0059] According to the required embossing depth of the extruded polystyrene board, the pressure of the embossing roller 18 on the extruded polystyrene board is adjusted by adjusting component 2: the vertical electric push rod 21 (embedded and installed at the top of the insulation frame 1) is started, and the moving part of the vertical electric push rod 21 drives the fixedly connected adjusting plate 22 to move. The adjusting plate 22 slides in the hollow plate 23. At the same time, the pressure sensor 24 installed at the bottom of the adjusting plate 22 monitors the pressure change of the spring 25 between it and the upper lifting lug 3 in real time. When the pressure detected by the pressure sensor 24 reaches the preset value (corresponding to the required embossing depth), the vertical electric push rod 21 stops running. At this time, the height position of the embossing roller 18 is fixed, and the embossing conditions are met.

[0060] Extruded polystyrene board heating and online embossing

[0061] Multiple heating tubes 10 are pre-activated to start heating, and at the same time, the heat-resistant fan 9 is activated. The heat-resistant fan 9 delivers hot air from the heating box 8 to the inside of the insulation frame 1 through multiple ventilation pipes 11 to heat the extruded board to be embossed inside the insulation frame 1, thereby improving the plasticity of the extruded board.

[0062] Multiple temperature sensors 12 installed on the inner wall of the insulation frame 1 monitor the temperature inside the insulation frame 1 in real time. When the temperature reaches the preset suitable temperature for embossing (set according to the material of the extruded board), the temperature sensor 12 sends a signal, which can be used to adjust the power and number of heating tubes 10 to maintain the temperature inside the insulation frame 1 stable.

[0063] Start the speed-regulating motor 13 (with the same speed as the speed-regulating motor 13 at the lower lifting lug 5) installed on the outer periphery of the upper lifting lug 3. The motor drives the embossing roller 18 connected to the inner wall of the upper lifting lug 3 via a rotating shaft to rotate. As the extruded board is continuously transported to the area below the embossing roller 18 by the conveyor belt 7, the rotating embossing roller 18 performs online embossing on the heated surface of the extruded board to form a preset pattern.
