Description

Technical Field

[0001] This utility model relates to the field of composite material processing technology, specifically to a double-sided coating device for composite materials. Background Technology

[0002] The reference patent title is: A Double-Sided Coating Device for Composite Materials (Authorization Announcement No.: CN220531943U, Authorization Announcement Date: 2024.02.27). It includes a placement box with coating material poured into its bottom. A guide plate is horizontally fixedly connected inside the placement box, positioned above the coating material. Rollers are sequentially mounted on both sides of the top of the front and back of the placement box's inner cavity, rotating vertically. A PVC membrane is drivenly connected to one side of the upper and lower sets of rollers that are close to each other. Multiple sets of boxes are sequentially fixedly connected on both sides of the center of the top of the front and back of the placement box's inner cavity, rotating vertically. An auxiliary mixing component is provided inside the placement box. This auxiliary mixing component facilitates stirring the coating material, turning the lower layer of coating to the upper layer. Combined with a second stirring blade, this ensures more thorough mixing. The multi-directional mixing method facilitates thorough and uniform mixing of the coating material, preventing sedimentation or agglomeration during use, which could affect the coating effect on the PVC membrane.

[0003] Based on the above document, composite materials have been widely used in aerospace, automobile manufacturing, construction engineering and other fields due to their excellent comprehensive properties. In the production and processing of composite materials, in order to improve their surface properties (such as corrosion resistance, wear resistance, aesthetics, etc.), it is usually necessary to coat their surface.

[0004] Currently, most existing composite material coating devices adopt a single-sided coating method, which requires flipping the composite material to complete double-sided coating. This is not only cumbersome to operate, but also reduces production efficiency. Although there are some double-sided coating devices, the nozzle positions of these devices are mostly fixed and cannot be flexibly adjusted according to the size of the composite material, resulting in uneven coating and paint waste. Therefore, this utility model provides a double-sided coating device for composite materials. Utility Model Content

Symmetrical nozzles 316 are fixedly connected to both sides of the moving blocks 315 and the adjustment blocks 314 respectively. The nozzles 316 are connected to each other via flexible hoses.

[0029] Linkage component 32 is located on the rear side of moving block 315 and adjusting block 314, and is used to realize equidistant adjustment of the positions of multiple sets of moving blocks 315;

[0030] The spraying assembly 33 is located on both sides of the coating box 2 and is used to perform the coating operation.

[0034] Adjustment 313 rotates inside the equipment frame 311;

[0035] The uppermost movable block 315 is fixedly connected to the upper inner wall of the equipment rack 311;

[0036] By setting spraying mechanisms 3 on both sides of the coating box 2, each spraying mechanism 3 is equipped with multiple nozzles 316, which can achieve simultaneous coating of both sides of the composite material without flipping it over, greatly improving the coating efficiency. Through the set adjustment component 31 and linkage component 32, the adjustment motor 312 drives the adjustment screw 313 to rotate, which can move the adjustment block 314. Then, through the linkage component 32, multiple sets of moving blocks 315 move synchronously and equidistantly, thereby realizing flexible adjustment of the nozzle position, which can adapt to composite materials of different sizes and ensure coating uniformity.

[0037] In this embodiment, the inner wall of the equipment frame 311 is fixedly connected with symmetrical limiting rods 4, and the surfaces of the limiting rods 4 are slidably connected to the interior of the moving block 315 and the adjusting block 314 respectively.

[0038] The limiting rod 4 is used to slide and limit the moving block 315 and the adjusting block 314.

[0039] In this embodiment, the linkage assembly 32 includes a linkage rod 321 and a connecting rod 322 rotatably mounted on the rear side of the adjusting block 314.

For example, one end of the rotating rod 323 on the rear side of the first set of moving blocks 315 is rotatably connected to one end of the rotating rod 324 on the rear side of the second set of moving blocks 315.

[0041] In this embodiment, the spraying assembly 33 includes a storage tank 331 installed on both sides of the coating box 2. The top of the storage tank 331 is fixedly connected to a pump 332 through a connecting pipe. The top of the pump 332 is fixedly connected to a guide pipe 333. One end of the guide pipe 333 extends into the interior of the coating box 2 and is fixedly connected to one end of the spray nozzle 316.

[0042] Pump 332 is a diaphragm metering pump equipped with a variable frequency motor, and the output pressure can be adjusted via the control panel;

[0043] In this embodiment, a symmetrical infrared laser sensor 5 is fixedly connected to the inner wall of the coating box 2 and to one side of the nozzle 316. A feed slot 6 is opened on the surface of the coating box 2, and a laser rangefinder 7 is installed at the bottom inside the feed slot 6.

[0044] Infrared laser sensor 5 uses a diffuse reflection sensor;

[0045] Laser rangefinder 7 is a triangular reflective laser rangefinder;

[0046] In this embodiment, a control panel 8 is installed on one side of the coating box 2. The control panel 8 is connected to the infrared laser sensor 5, the laser rangefinder 7, the overhead conveyor 1, the regulating motor 312, and the pump 332.

[0047] The control panel 8 adopts a PLC control system and is equipped with a 7-inch touch screen. It can display equipment operating parameters (conveying speed, spraying pressure, nozzle position, etc.) and supports manual / automatic mode switching. The panel has a built-in relay module to realize the switching control of each actuator. It is equipped with an emergency stop button and status indicator lights.

[0048] By incorporating an infrared laser sensor 5, a laser rangefinder sensor 7, and a control panel 8, the position and size of the composite material can be automatically detected. Based on the detection results, the position of the nozzle 316, the conveying speed, and the spraying parameters can be automatically adjusted, thus achieving automated control of the coating process and improving coating quality and production efficiency.

[0049] Furthermore, any content not described in detail in this specification is prior art known to those skilled in the art.

[0050] In use, the composite material to be coated is suspended on the overhead conveyor 1. The overhead conveyor 1 transports the composite material through the feed trough 6 into the coating box 2. When the composite material enters the feed trough 6, the laser range sensor 7 detects its size and transmits the signal to the control panel 8. The control panel 8 controls the adjustment motor 312 to start according to the detected size information. The adjustment motor 312 drives the adjustment screw 313 to rotate. The adjustment screw 313 drives the adjustment block 314 to move along the limit rod 4. The adjustment block 314 drives multiple sets of moving blocks 315 to move synchronously and equidistantly through the linkage component 32, thereby adjusting the position of the nozzle 316 to match the size of the composite material.

[0051] When the infrared laser sensor 5 detects that the composite material has reached the spraying position of the nozzle 316, it transmits a signal to the control panel 8. The control panel 8 controls the pump 332 to start. The pump 332 transports the paint in the storage tank 331 to the nozzle 316 through the connecting pipe and the guide pipe 333. The nozzle 316 sprays the paint onto both sides of the composite material, achieving simultaneous coating on both sides. During the coating process, the control panel 8 adjusts the running speed of the overhead conveyor 1 and the working status of the pump 332 in real time according to the preset program and the detected signal to ensure the coating quality. After the coating is completed, the overhead conveyor 1 transports the composite material out of the coating box 2.
