[0012] Preferably, a roller conveyor mechanism is rotatably mounted inside the support frame, and a protective shell is installed on the inner wall of the support frame, the protective shell being located outside the conveying component in the roller conveyor mechanism.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a pressure-adjustable carbon fiber plate pressing device, including a support frame 1, a control panel 12 installed on one side of the support frame 1, a pressure adjustment mechanism 2 provided at the upper end of the support frame 1, and a limit adjustment mechanism 3 provided on the inner side of the support frame 1.

[0024] The pressure regulating mechanism 2 includes two sets of support plates 21. Each set of support plates 21 has a concave seat 22 installed at its upper end. Each set of concave seats 22 has a cylinder 23 installed at its upper end. Each set of concave seats 22 has a bearing seat 24 inside. A rotating rod 25 is rotatably installed in the middle of each set of bearing seats 24. A pressure roller 26 is installed on the outer wall of the rotating rod 25. A pressure sensor 27 is installed on the outer wall of the rotating rod 25. The lower ends of the two sets of support plates 21 are fixed to the upper ends of the support frame 1. The protruding ends of the two sets of cylinders 23 pass through the upper ends of the two sets of concave seats 22 and are respectively fixed to the upper ends of the two sets of bearing seats 24. Each set of concave seats 22 has a guide rail 28 installed on its inner wall. Each set of guide rails 28 has a sliding seat 29 slidably installed on its outer wall. One end of each set of bearing seats 24 is respectively fixed to one end of each set of sliding seats 29. The two sets of cylinders 23 and pressure sensors 27 are all connected to the control panel 12 via signals.

[0025] A roller conveyor mechanism 11 is rotatably mounted inside the support frame 1, and a protective shell 13 is installed on the inner wall of the support frame 1. The protective shell 13 is located outside the conveying component in the roller conveyor mechanism 11.

[0026] The specific settings and functions of this embodiment are described below. The support frame 1 serves as the load-bearing foundation of the entire device and is made of high-strength alloy material to ensure structural stability during the pressing operation. A control panel 12 is integrated on one side of the support frame 12. The control panel 12 is equipped with a high-definition display screen and a touch operation area, which can display parameters such as pressing pressure and conveying speed in real time, and supports manual input of pressure threshold and adjustment of conveying rate.

[0027] The support frame 1 is equipped with a roller conveyor mechanism 11, which consists of multiple evenly distributed conveyor rollers connected by chain drive and driven by a servo motor (the motor is integrated inside the support frame 1). It can realize the smooth and continuous conveying of carbon fiber sheets. The conveying speed can be infinitely adjusted by the control panel 12 to adapt to the pressing requirements of carbon fiber sheets of different thicknesses.

[0028] In addition, a protective shell 13 is installed on the inner wall of the support frame 1. The protective shell 13 is made of wear-resistant plastic material and is located on the outside of the conveying component in the roller conveyor mechanism 11 in a semi-enclosed shape. It can prevent the debris generated during the pressing process from entering the conveying mechanism and affecting the operation, and can also prevent the operator from accidentally touching the rotating parts and causing safety hazards.

[0029] The pressure regulating mechanism 2 is the core component for achieving precise pressure control. It includes two sets of symmetrically distributed support plates 21. The two sets of support plates 21 are vertically fixed on both sides of the upper end of the support frame 1. Each of them has a concave seat 22 fastened to its upper end by bolts. The concave seat 22 is made of cast steel and has an internal accommodating space. A cylinder 23 is vertically installed at the center of the upper end face.

[0030] Both sets of concave seats 22 are equipped with bearing seats 24 inside. The bearing seats 24 adopt a split structure and have built-in high-precision ball bearings. A rotating rod 25 is rotatably installed in the middle of the two sets of bearing seats 24. The rotating rod 25 is made of high-strength alloy steel, and a pressing roller 26 is fixedly installed on its outer wall by a key connection. The surface of the pressing roller 26 is covered with a wear-resistant rubber layer. The hardness of the rubber layer can be selected according to the material of the carbon fiber plate, which can ensure that the pressing force is evenly transmitted and avoid scratching the surface of the carbon fiber plate.

[0031] A pressure sensor 27 is embedded in the outer wall of the rotating rod 25. The pressure sensor 27 is a strain gauge sensor that can detect the pressure value of the pressing roller 26 on the carbon fiber plate in real time and transmit the data to the control panel 12 in real time.

[0032] The lower ends of the two sets of support plates 21 are fixed to the upper ends of the support frame 1 by welding to ensure the overall stability of the pressure regulating mechanism 2. The protruding ends of the two sets of cylinders 23 pass through the upper center holes of the two sets of concave seats 22 and are rigidly connected to the upper ends of the two sets of bearing seats 24 through flanges respectively. When the cylinders 23 extend and retract, they can directly drive the bearing seats 24 to move up and down.

[0033] To ensure the moving accuracy of the bearing seat 24, guide rails 28 are vertically installed on the inner walls of both sets of concave seats 22. The guide rails 28 are linear slide rails, and slide blocks 29 are slidably installed on their outer walls. One end of each set of bearing seats 24 is fixedly connected to one end of each set of slide blocks 29 by bolts, so that the bearing seat 24 moves vertically back and forth along the guide rails 28 under the drive of the cylinder 23, avoiding lateral displacement of the pressing roller 26 and ensuring that the pressure application direction is perpendicular to the surface of the carbon fiber plate.

[0034] Both sets of cylinders 23 and pressure sensors 27 are connected to the control panel 12 via shielded cables to form a closed-loop control system: when the pressure value detected by the pressure sensor 27 is lower than the preset threshold of the control panel 12, the control panel 12 sends an extension command to the cylinder 23 to increase the downward pressure of the pressing roller 26; when the detected value is higher than the preset threshold, a contraction command is sent to reduce the downward pressure, thereby realizing automatic dynamic adjustment of the pressure.

[0035] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the limit adjustment mechanism 3 includes a baffle 32, and a fixing plate 31 is installed on the other side of the support frame 1. A telescopic rod 33 is installed at one end of each of the two fixing plates 31. A semi-circular hole 34 is opened through one end of the baffle 32. The baffle 32 is set inside the support frame 1. The extended ends of the two telescopic rods 33 pass through one end of the two fixing plates 31 and are fixed to one end of the baffle 32.

[0036] The overall effect of the embodiment is that the limit adjustment mechanism 3 is used to ensure that the carbon fiber plate does not shift laterally during the conveying and pressing process. It includes a baffle 32, a fixed plate 31 and a telescopic rod 33. Two sets of fixed plates 31 are symmetrically welded on the other side of the support frame 1. The fixed plate 31 is perpendicular to the support frame 1. A telescopic rod 33 is installed at the center of one end of the fixed plate 31. The telescopic rod 33 is an electric push rod.

[0037] The baffle 32 is made of high-strength transparent acrylic sheet, which makes it easy for operators to observe the alignment of the carbon fiber sheet. Multiple semi-circular holes 34 are opened through one end of the baffle (the hole diameter matches the diameter of the conveying roller of the roller conveying mechanism 11). When the baffle 32 moves, the semi-circular holes 34 can fit against the outer wall of the conveying roller to avoid obstructing the conveying process.

[0038] The baffle 32 is installed inside the support frame 1, above the roller conveyor mechanism 11. The extended ends of the two sets of telescopic rods 33 pass through the through holes at one end of the two sets of fixed plates 31 and are fixed to one end of the baffle 32 by threaded connection. The operator can control the telescopic rods 33 to extend and retract through the control panel 12, which drives the baffle 32 to move in the vertical direction of the carbon fiber plate conveying direction. With the help of the protective shell 13, the baffle 32 can be adjusted to limit the position of different carbon fiber plates.

[0039] The usage method and working principle of this device are as follows: First, the operator sets the parameters through the control panel 12, including inputting the preset pressing pressure threshold and the appropriate conveying speed of the roller conveyor mechanism 11 according to the thickness, material and other characteristics of the carbon fiber plate.

[0040] When the device is started, the roller conveyor mechanism 11 starts to operate under the drive of the servo motor. Multiple conveying rollers rotate synchronously through chain drive. At this time, the carbon fiber plate is placed at the input end of the roller conveyor mechanism 11. The carbon fiber plate moves smoothly to the position of the pressure regulating mechanism 2 under the drive of the conveying roller.

[0041] During the carbon fiber sheet conveying process, the limit adjustment mechanism 3 plays a role. The operator can control the extension and retraction of the two sets of telescopic rods 33 through the control panel 12. Since the extended end of the telescopic rod 33 is connected to the baffle 32, the baffle 32 will move in the direction perpendicular to the conveying direction of the carbon fiber sheet. According to the width of the carbon fiber sheet, the distance between the baffle 32 and the side wall of the protective shell 13 is adjusted so as to limit the two sides of the carbon fiber sheet. At the same time, the semi-circular hole 34 on the baffle 32 fits against the outer wall of the conveying roller, avoiding interference with the conveying process and ensuring that the carbon fiber sheet does not shift laterally during the conveying process and always maintains the correct conveying posture.

[0042] When the carbon fiber sheet is conveyed to the pressure roller 26 of the pressure regulating mechanism 2, the pressing operation begins. The cylinder 23 in the pressure regulating mechanism 2 receives the command from the control panel 12, and its extended end pushes the bearing seat 24 downward. Since one end of the bearing seat 24 is fixed to the slide 29, and the slide 29 slides on the guide rail 28, the bearing seat 24 is ensured to move smoothly in the vertical direction, thereby driving the rotating rod 25 and the pressure roller 26 to move downward synchronously until the pressure roller 26 contacts the surface of the carbon fiber sheet and applies pressure.

[0043] During the pressing process, the pressure sensor 27 on the outer wall of the rotating rod 25 detects the pressure value of the pressing roller 26 on the carbon fiber plate in real time, and transmits the detected pressure data to the control panel 12 through the shielded cable. The control panel 12 compares the real-time pressure value with the preset pressure threshold: if the real-time pressure value is lower than the preset threshold, the control panel 12 sends an extension command to the cylinder 23, the cylinder 23 continues to extend, pushing the pressing roller 26 to press down further, increasing the pressing pressure; if the real-time pressure value is higher than the preset threshold, the control panel 12 sends a contraction command to the cylinder 23, the cylinder 23 contracts, driving the pressing roller 26 to move upward, reducing the pressing pressure, thereby forming a closed-loop control to ensure that the pressing pressure is always maintained within the preset threshold range.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
