[0002] Fiberglass board is made of fiberglass and high heat-resistant composite materials. It has high mechanical and dielectric properties, good heat and moisture resistance, and good processability. It is widely used in machinery manufacturing, motors, PCBs, batteries and other fields.

[0003] The production of fiberglass boards involves steps such as raw material impregnation, compression molding, thermosetting, and post-molding treatment. During the compression process of fiberglass boards (such as PCBs or composite laminates), venting is a key step to ensure material density and avoid bubbles and delamination. The main raw material used in the production of fiberglass boards is resin, which has a gel point of 90-110°C. During the process of reaching the gel point, the resin can flow slowly, and the gas inside the resin can be discharged through the resin flow. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pressing device for the production of glass fiberboard that is easy to vent, so as to solve the problem of gas discharge from the resin mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing device for producing glass fiberboard that is easy to vent, comprising a base, a conveyor belt on the base, a pressing groove on the conveyor belt, a progressive heating mechanism inside the base below the pressing groove, pressing mechanism support frames on both sides of the conveyor belt, a segmented pressing mechanism on the pressing mechanism support frames, and a PLC controller on the pressing mechanism support frames, wherein the PLC controller is electrically connected to the progressive heating mechanism and the segmented pressing mechanism;

[0006] The progressive heating mechanism includes a heating plate, a heating switch, a first heating tube, a second heating tube, and a third heating tube. The heating plate is fixed below the conveyor belt, and the heating switch is fixed at the bottom of the heating plate. The first heating tube, the second heating tube, and the third heating tube are arranged sequentially inside the heating plate. The heating switch is electrically connected to the first heating tube, the second heating tube, and the third heating tube, and is also electrically connected to the PLC controller.

[0007] In a preferred embodiment of this invention, the segmented pressing mechanism includes a pressing electric cylinder, a temperature sensor, a connecting rod, and a pressing plate; the pressing electric cylinder is fixed on the pressing mechanism support frame, the pressing electric cylinder is electrically connected to the PLC controller, the output end of the pressing electric cylinder is fixedly connected to the connecting rod, the bottom of the connecting rod is fixedly connected to the pressing plate, the bottom of the pressing plate is embedded with a temperature sensor, and the temperature sensor is electrically connected to the PLC controller.

[0008] As a preferred embodiment of this invention, the pressing plate is provided with gas venting holes.

[0009] In a preferred embodiment of this invention, the first heating tube is arranged in an S-shape at the bottom of the heating plate, and a second heating tube and a third heating tube are fixed on both sides of the first heating tube, and the second heating tube and the third heating tube are both arranged in an S-shape and evenly distributed at the bottom of the heating plate.

[0010] As a preferred embodiment of this utility model, a drive servo motor mounting base is provided on one side of the conveyor belt, a drive servo motor is provided on the drive servo motor mounting base, a drive wheel is fixedly connected to the drive shaft of the drive servo motor, and the drive wheel is rotatably connected inside the conveyor belt.

[0011] As a preferred embodiment of this invention, anti-slip pads are provided on both sides of the bottom of the pressing groove, and the anti-slip pads are placed on the conveyor belt.

[0012] In a preferred embodiment of this invention, the bottom of the pressing groove is attached to the heating plate after it is placed on the conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention employs a progressive heating mechanism. A PLC controller activates the heating switch, which in turn controls the first heating element to heat the heating plate to 50°C. After heating for a period of time, the heating switch controls the second heating element to heat the heating plate to 80°C. After further heating for a period of time, the heating switch controls the third heating element to heat the heating plate to 120°C. This causes the resin to flow slowly as the temperature rises, allowing internal gases to escape as the resin flows.

[0015] This invention uses a temperature sensor at the bottom of the pressing plate. During the heating stage, the pressure of the pressing plate on the pressing groove is in the first stage (low pressure), which facilitates the flow of resin during the heating process and facilitates the discharge of gas. When the temperature rises to the resin gel point, the temperature sensor detects it and feeds back to the PLC controller. The PLC controller controls the pressing cylinder to pressurize, and the pressing plate presses the pressing groove to the second stage (high pressure), compacting the interlayer structure and completing the glass fiber board pressing process.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, this utility model provides a pressing device for producing glass fiberboard that is easy to vent, including a base 1, a conveyor belt 2 on the base 1, a pressing groove 3 on the conveyor belt 2, a progressive heating mechanism 4 inside the base 1 below the pressing groove 3, pressing mechanism support frames 5 on both sides of the conveyor belt 2, a segmented pressing mechanism 6 on the pressing mechanism support frame 5, and a PLC controller 7 on the pressing mechanism support frame 5. The PLC controller 7 is electrically connected to the progressive heating mechanism 4 and the segmented pressing mechanism 6.

[0022] refer to Figure 1-2The progressive heating mechanism 4 includes a heating plate 401, a heating switch 402, a first heating tube 403, a second heating tube 404, and a third heating tube 405. The heating plate 401 is fixed below the conveyor belt 2, and the heating switch 402 is fixed at the bottom of the heating plate 401. The first heating tube 403, the second heating tube 404, and the third heating tube 405 are sequentially distributed inside the heating plate 401. The heating switch 402 is electrically connected to the first heating tube 403, the second heating tube 404, and the third heating tube 405, and is also electrically connected to the PLC controller 7. The first heating tube 403 is arranged in an S-shape at the bottom of the heating plate 401. The second heating tube 404 and the third heating tube 405 are fixed on both sides of the first heating tube 403, and the second heating tube 404 and the third heating tube 405 are both arranged in an S-shape and evenly distributed at the bottom of the heating plate 401.

[0023] By installing a progressive heating mechanism 4, the PLC controller 7 controls the heating switch 402 to start, which in turn controls the first heating tube 403 to heat the heating plate 401 to 50°C. After heating for a period of time, the heating switch 402 controls the second heating tube 404 to heat the heating plate 401 to 80°C. After continuing to heat for a period of time, the heating switch 402 controls the third heating tube 405 to heat the heating plate 401 to 120°C, so that the resin flows slowly as the temperature rises, and the internal gas is discharged as the resin flows.

[0024] refer to Figure 1 The segmented pressing mechanism 6 includes a pressing electric cylinder 601, a temperature sensor 602, a connecting rod 603, and a pressing plate 604. The pressing electric cylinder 601 is fixed on the pressing mechanism support frame 5 and is electrically connected to the PLC controller 7. The output end of the pressing electric cylinder 601 is fixedly connected to the connecting rod 603, and the bottom of the connecting rod 603 is fixed to the pressing plate 604. The bottom of the pressing plate 604 is embedded with the temperature sensor 602, and the temperature sensor 602 is electrically connected to the PLC controller 7.

[0025] During the heating stage, the pressure of the pressing plate 604 on the pressing groove 3 is in the first stage (low pressure) through the temperature sensor 602 at the bottom of the pressing plate 604. This facilitates the flow of resin during the heating process and the discharge of gas. When the temperature rises to the resin gel point, the temperature sensor 602 detects the temperature and sends feedback to the PLC controller 7. The PLC controller 7 controls the pressing cylinder 601 to pressurize, and the pressing plate 604 pressurizes the pressing groove 3 to the second stage (high pressure), compacting the interlayer structure and completing the glass fiber board pressing process.

[0026] The working principle and usage process of this utility model are as follows: Raw material (resin) is introduced into the pressing tank 3, which is placed on the conveyor belt 2. As the drive servo motor 202 starts, the pressing tank 3 is fed below the segmented pressing mechanism 6. The PLC controller 7 controls the drive servo motor 202 to stop working, and the progressive heating mechanism 4 starts. The raw material (resin) reaches its gel point at 90-110°C. The heating switch 402 is activated, controlling the first heating tube 403 to heat the heating plate 401 to 50°C. The first heating tubes 403 are S-shaped and distributed at the bottom of the heating plate 401 to ensure more uniform heating. After heating for a period of time, the heating switch 402 controls the second heating tube 404 to heat the heating plate 401 to 80°C. After continuing heating for a period of time, the heating switch 402 controls the third heating tube 405 to heat... The heating plate 401 is heated to 120°C, causing the resin to flow slowly as the temperature rises. As the resin flows, the internal gas is expelled. During the heating stage, the pressure of the pressing plate 604 on the pressing tank 3 is in the first stage (low pressure), which facilitates the flow of the resin during the heating process and the expulsion of gas. When the temperature rises to the resin gel point, the temperature sensor 602 detects it and feeds back to the PLC controller 7. The PLC controller 7 controls the pressing cylinder 601 to pressurize, and the pressing plate 604 pressurizes the pressing tank 3 to the second stage (high pressure), compacting the interlayer structure. Gas venting holes 605 are opened on the pressing plate 604 to help the gas escape. After the pressing process is completed, the PLC controller 7 controls the drive servo motor 202 to start and push the pressing tank 3 out.
