Description

Technical Field

[0001] This utility model belongs to the field of composite material processing equipment, specifically an automatic foam board bonding device based on infrared temperature sensing. Background Technology

[0002] In the manufacturing process of composite materials such as wind turbine blade core materials, a layer of backing fiber cloth needs to be hot-pressed and bonded to one side of the foam board to enhance its structural strength and facilitate subsequent deep groove processing on the other side of the foam board. Otherwise, if the bottom of the groove is only 2mm thick after deep groove cutting, the entire foam board is prone to breakage. Existing technology typically uses a bonding machine with rollers for this operation. The rollers have a certain temperature, which is manually set by the operator on the touch screen control panel of the control box. The temperature of the rollers can activate the hot melt adhesive layer on the back of the backing fiber cloth, melting it and achieving a firm bond with the foam board surface under the pressure of the rollers. Therefore, the surface temperature of the rollers is a key process parameter that directly determines the bonding effect.

[0003] However, the actual surface temperature of the rollers in existing fabric bonding machines cannot be accurately and in real-time monitored. The touchscreen control panel only sets the theoretical temperature, and due to seasonal changes, ambient temperature, and other factors, the actual surface temperature of the rollers often deviates from the set temperature. For example, in winter when the ambient temperature is low, even if the set temperature is 175℃, the actual surface temperature of the rollers may gradually drop to 155℃ or even lower after a period of operation due to increased heat loss. However, because the actual surface temperature of the rollers is detected manually using a handheld infrared thermometer at regular intervals (e.g., every 4 hours), there is a monitoring blind spot of several hours between the temperature drop and the next inspection. During this blind spot, the equipment is actually operating continuously at substandard low temperatures, directly causing a large number of foam boards to fail to bond properly due to insufficient bonding temperature, and this problem cannot be detected and adjusted in time. Furthermore, the handheld infrared thermometer method itself is subject to subjective influences from the measurement distance and location selection, resulting in insufficient representativeness of the measurement results and failing to reflect the continuous and true state of the roller temperature during production. This results in the temperature of the fabric bonding process being in a passive state that is imprecise and uncontrollable for a long time, which in turn causes the fabric bonding effect of foam boards to be unstable. This leads to a batch of quality defects such as poor adhesion due to excessively low temperature or scorching of the boards due to excessively high temperature, making it difficult to guarantee the yield rate. Utility Model Content

[0004] The present invention aims to provide an automatic fabric bonding device for foam boards based on infrared temperature sensing, in order to solve the problem in the prior art where the actual temperature monitoring of the rollers is inaccurate and not real-time, which leads to unstable fabric bonding quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic foam board bonding device based on infrared temperature sensing includes a control box, a frame, a conveying mechanism mounted on the frame, a fabric unwinding mechanism for unwinding the backing fiber fabric, and a heating and pressurizing mechanism for hot pressing the foam board after it has been backed with fabric. The heating and pressurizing mechanism includes a heating roller. Both the conveying mechanism and the heating roller are driven to rotate by a power component, which is electrically connected to the control box. An infrared temperature sensing device for measuring the surface temperature of the heating roller is mounted on the frame near the heating roller. The infrared temperature sensing device includes an infrared temperature sensor and a temperature display screen that are electrically connected. The signal output terminal of the infrared temperature sensor is communicatively connected to the signal input terminal of the control box.

[0006] As a limitation of this utility model: the surface of the heating roller is covered with Teflon cloth.

[0007] As a further limitation of this utility model: the heating and pressurizing mechanism also includes a pressure roller rotatably mounted on the frame, the pressure roller being located downstream of the heating roller along the conveying direction of the foam board; the pressure roller is driven to rotate by a pressure roller power component, the pressure roller power component being electrically connected to the control box; the pressure roller and the heating roller rotate at the same speed, and the lowest point of the pressure roller and the lowest point of the heating roller are at the same height.

[0008] As a further limitation of this utility model: the distance between the lowest point of the heating roller and the conveying mechanism is less than the thickness of the foam board.

[0009] As a further limitation of this utility model, it also includes a temperature circulation control mechanism for heating the heating roller. The temperature circulation control mechanism includes a heat-conducting oil tank, a first heat-conducting oil pipe, and a second heat-conducting oil pipe. The heating roller has a hollow cavity inside. The output end of the heat-conducting oil tank is connected to one end of the heating roller through the first heat-conducting oil pipe, and the other end of the heating roller is connected back to the input end of the heat-conducting oil tank through the second heat-conducting oil pipe, forming a closed loop. The heat-conducting oil tank is electrically connected to the control box, and the output oil temperature of the heat-conducting oil tank is set and controlled by the control box.

[0010] As a further limitation of this utility model, it also includes an electric heating mechanism for heating the heating roller. The heating roller has a solid structure, and the heating element of the electric heating mechanism is embedded inside the heating roller. The electric heating mechanism is electrically connected to the control box, and the heating power of the heating element is set and controlled by the control box.

[0011] As another limitation of this utility model, it also includes an automatic cutting mechanism for cutting the continuous backing fiber cloth between adjacent foam boards. The automatic cutting mechanism includes two parallel fixed guide rails fixed on the frame and spanning the conveying mechanism; it also includes a sliding crossbeam disposed between the two fixed guide rails. The sliding crossbeam is slidably connected to the two fixed guide rails through a first slider, and the direction of movement of the sliding crossbeam on the fixed guide rails is perpendicular to the direction of foam board conveying. A cutting component is provided on the sliding crossbeam. The cutting component is slidably connected to the sliding crossbeam via a second slider. The moving direction of the cutting component is along the length direction of the sliding crossbeam. The sliding beam is driven by the first driving component to move along the fixed guide rail, and the cutting component is driven by the second driving component to move along the sliding beam. Both the first and second driving components are electrically connected to the control box. The control box controls the moving speed and trajectory of the sliding beam and the cutting component. The movement path of the cutting component is synchronized with the feeding of the foam board to complete the cutting of the backing fiber cloth between adjacent foam boards in a cyclical manner.

[0012] As a further limitation of this utility model: the cutting part is a double-edged cutting scissors.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: This invention features an infrared temperature sensor mounted on the frame near the heating roller to measure its surface temperature. The signal output of the infrared temperature sensor is communicatively connected to the signal input of the control box. The infrared temperature sensor enables continuous, non-contact, online real-time monitoring of the heating roller's surface temperature. When the surface temperature falls below the set temperature, the infrared temperature sensor sends a feedback signal to the control box, which then controls the temperature circulation control mechanism or the electric heating mechanism to continue heating the heating roller, increasing its temperature and ensuring that the fabric bonding process always occurs within the optimal temperature range, thereby improving product consistency and yield.

[0014] In summary, this invention enables real-time and accurate monitoring of the surface temperature of the heating roller, thereby improving the quality of fabric application. This invention is applicable to all scenarios where fabric needs to be applied to boards. Attached Figure Description

Detailed Implementation

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and do not constitute a limitation thereof.

[0019] The directional terms or positional relationships such as "left," "right," "front," and "back" used in the embodiments are based on the drawings in this utility model specification. Figure 2 The orientation relationships are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the content protected by this utility model.

[0020] like Figures 1 to 7 As shown, this embodiment includes a control box 1, a frame 2, a conveying mechanism mounted on the frame 2, a fabric unwinding mechanism 3 for unwinding the backing fiber cloth 17, and a heating and pressurizing mechanism for hot-pressing the foam board 4 after fabric covering. The heating and pressurizing mechanism includes a heating roller 5. Both the conveying mechanism and the heating roller 5 are driven to rotate by a power component, which is electrically connected to the control box 1. Specifically, the conveying mechanism includes a conveyor roller and a conveyor belt 6 mounted on the conveyor roller. The conveyor belt 6 is used to convey the foam board 4. The power component uses existing servo motors. The heating roller 5 and the conveyor roller in the conveying mechanism are each driven to rotate by a servo motor. The two servo motors have the same speed but opposite directions. The servo motors are controlled by the control box 1 to start, stop, and adjust their speed. This part is prior art.

[0021] The main improvement in this embodiment is as follows: 1. Install an infrared temperature sensing device; like Figure 1 , 4As shown in Figure 5, an infrared temperature sensing device for measuring the surface temperature of the heating roller 5 is installed on the frame 2 near the heating roller 5. The infrared temperature sensing device includes an infrared temperature sensor 7 and a temperature display screen 8, which are electrically connected. Both the infrared temperature sensor 7 and the temperature display screen 8 are existing structures. In this embodiment, a mounting plate 9 spanning the conveyor belt 6 is fixed on the frame 2. The infrared temperature sensor 7 is fixed on the mounting plate 9 with its probe facing the heating roller 5. The temperature display screen 8 is fixed on the frame 2 and is installed in a conspicuous and easily accessible position. In this embodiment, it is installed on the side of the frame 2. The temperature display screen 8 allows production personnel to easily view and record parameters such as time and temperature of the equipment. The infrared temperature sensor 7 is used to achieve continuous, non-contact, online real-time monitoring of the surface temperature of the heating roller 5. The signal output terminal of the infrared temperature sensor 7 is communicatively connected to the signal input terminal of the control box 1, and the infrared temperature sensor 7 can transmit the detected temperature signal to the PLC of the control box 1 in real time. When the surface temperature of the heating roller 5 is lower than the set temperature, the infrared temperature sensor 7 sends a feedback signal to the control box 1. The control box 1 then controls the temperature cycle control mechanism or the electric heating mechanism to continue heating the heating roller 5, thereby increasing the temperature of the heating roller 5 and ensuring that the fabric bonding process is always carried out within the optimal temperature range.

[0022] It should be noted that the heating structure of the heating roller 5 can be achieved in two ways: The first method utilizes a temperature circulation control mechanism, which is adopted in this embodiment. The temperature circulation control mechanism includes a heat transfer oil tank 10, a first heat transfer oil pipe, and a second heat transfer oil pipe (the first and second heat transfer oil pipes are not shown in the figure). The heating roller 5 has a hollow cavity inside. The output end of the heat transfer oil tank 10 is connected to one end of the heating roller 5 through the first heat transfer oil pipe, and the other end of the heating roller 5 is connected back to the input end of the heat transfer oil tank 10 through the second heat transfer oil pipe, forming a closed loop. The heat transfer oil tank 10 is electrically connected to the control box 1, and the output oil temperature of the heat transfer oil tank 10 is set and controlled by the control box 1.

[0023] The second method is to use an electric heating mechanism. The heating roller 5 is a solid structure. The heating element of the electric heating mechanism is embedded inside the heating roller 5. The electric heating mechanism is electrically connected to the control box 1. The heating power of the heating element is set and controlled by the control box 1.

[0024] Both of the above heating methods are existing technologies and will not be described in detail in this embodiment.

[0025] II. Install Teflon fabric; The surface of the heating roller 5 is covered with Teflon cloth, which is fixed to the surface of the heating roller 5 with high-temperature resistant tape. The Teflon cloth has a low coefficient of friction and has properties such as anti-sticking, corrosion resistance, flame retardancy, and insulation. The Teflon cloth can prevent dust from adhering to the surface of the heating roller 5 and also prevent the foam board 4 from being scorched by the heating roller 5.

[0026] III. Pressure Roller 11; To ensure a stronger bond between the backing fiber cloth 17 and the foam board 4 after initial hot pressing by the heated rollers 5, such as... Figure 3 As shown, this embodiment adds a pressure roller 11 to the heating and pressurizing mechanism. The pressure roller 11 is rotatably mounted on the frame 2 via bearing seats at both ends (not shown in the figure). In this embodiment, three pressure rollers 11 are provided, arranged in parallel, with their axial direction parallel to that of the heating roller 5. The pressure rollers 11 are located downstream of the heating roller 5 along the conveying direction of the foam board 4 (from front to back). The foam board 4 first passes through the heating roller 5 for primary heat melting and initial pressurization, and then enters the area of ​​the pressure rollers 11 for secondary pressing, ensuring the stability of the adhesion. The pressure rollers 11 are driven to rotate by a pressure roller power component. Specifically, the pressure roller power component uses an existing servo motor. The three pressure rollers 11 are synchronously driven by the servo motor, gears, and chains. A gear is fixedly fitted at one end of each of the three pressure rollers 11, and the chain is fitted onto the three gears. The servo motor drives one of the pressure rollers 11 to rotate, and the chains enable the three pressure rollers 11 to rotate synchronously. This driving method is existing technology and will not be described in detail here.

[0027] The pressure roller power component is electrically connected to the control box 1; the control box 1 controls the power component and the pressure roller power component to rotate at the same speed, so that the pressure roller 11 and the heating roller 5 rotate at the same speed. The lowest point of the pressure roller 11 and the lowest point of the heating roller 5 are at the same height, which ensures that the foam board 4 can smoothly and evenly contact the pressure roller 11 and the heating roller 5 simultaneously and bear the pressure during horizontal conveying, avoiding the problem of warping or uneven force on the foam board 4 due to inconsistent height.

[0028] In order to apply effective pressure to the foam board 4, the vertical distance between the lowest point of the heating roller 5 and the conveying mechanism is less than the thickness of the foam board 4. In this embodiment, the vertical distance between the lowest point of the heating roller 5 and the bearing surface of the conveying mechanism (i.e., the upper surface of the conveyor belt 6) is 5 mm less than the thickness of the foam board 4.

[0029] IV. Automatic cutting mechanism; This embodiment also includes an automatic cutting mechanism for cutting the continuous backing fiber cloth 17 between adjacent foam boards 4.

[0030] like Figure 2 , 3As shown in Figures 4, 6, and 7, the automatic cutting mechanism includes two parallel fixed guide rails 12 fixed to the frame 2 and spanning the conveying mechanism. Two vertical plates 13 are fixed to the upright plate 201 of the frame 2, spanning above the conveying mechanism, and each vertical plate 13 has a fixed guide rail 12 fixed to it. The extending direction of the fixed guide rails 12 is perpendicular to the conveying direction of the foam board 4; in other words, the fixed guide rails 12 extend in the left and right directions, and the foam board 4 is conveyed from front to back. A cover plate 18 is fixedly connected above the two vertical plates 13, covering the automatic cutting mechanism and the three pressure rollers 11.

[0031] It also includes a sliding crossbeam 14 disposed between two fixed guide rails 12. Each end of the sliding crossbeam 14 is slidably connected to the fixed guide rail 12 via a first slider. The direction of movement of the sliding crossbeam 14 on the fixed guide rail 12 (left and right) is perpendicular to the conveying direction of the foam board 4 (front and back). The sliding crossbeam 14 is driven to move along the fixed guide rail 12 by a first driving component. Specifically, the first driving component includes a motor, a pulley mechanism, and a lead screw. A lead screw is rotatably mounted on both the front and rear vertical plates 13 via a lead screw seat. The input ends of the two lead screws are each connected to the same motor output shaft via a pulley mechanism. Each lead screw is threaded with a first slider. The method of using a first driving component to achieve linear movement of the first slider is existing technology; neither the first driving component nor the first slider is shown in the figure. In use, the motor rotates, driving the two lead screws to rotate synchronously. Under the threaded engagement, the first slider can only move linearly along the axis of the lead screw, causing the sliding crossbeam 14 to move in the left and right directions.

[0032] A cutting element 15 is mounted on the sliding beam 14. The cutting element 15 is slidably connected to the sliding beam 14 via a second slider. The cutting element 15 moves along the length of the sliding beam 14, that is, it moves in the forward and backward directions. The cutting element 15 is driven to move along the sliding beam 14 by a second driving member, which is an electric push rod fixed to one end of the sliding beam 14. The electric push rod can also push the cutting element 15 to move in the forward and backward directions while moving with the sliding beam 14. The electric push rod and the second slider are not shown in the figure.

[0033] Both the first and second drive components are electrically connected to the control box 1. The PLC inside the control box 1 controls the start, stop, and speed of the first and second drive components, thereby controlling the moving speed and trajectory of the sliding beam 14 and the cutting component 15, ensuring that the movement path of the cutting component 15 is synchronized with the feeding of the foam board 4, so as to cyclically complete the cutting of the backing fiber cloth 17 between adjacent foam boards 4.

[0034] Description of the cutting trajectory: like Figure 6As shown, for ease of description, we define the X-axis and Y-axis directions. The X-axis direction is the left and right direction, and the Y-axis direction is the front and back direction.

[0035] Initial position: Cutting piece 15 is located at Figure 6 The starting point (point A) of the first path 19 shown in the figure.

[0036] First path 19 (synchronous cutting): When a string of foam boards 4 with continuous backing fiber cloth 17 is fed at a constant speed on the conveyor mechanism, the gap between the first and second boards at the front moves to below the cutting area and corresponds to point A. The control box 1 simultaneously controls the first and second drive components, so that the moving speed of the cutting piece 15 in the Y-axis direction is exactly the same as the feeding speed of the foam board 4. At the same time, the control box 1 controls the first drive component to work, so that the sliding beam 14 and the cutting piece 15 move together from left to right in the X-axis direction. The actual movement path of the cutting piece 15 is a diagonal straight line (i.e., the first path 19), and its Y-axis velocity is synchronized with that of the foam board 4, ensuring that the cutting piece 15 is "stationary" in the forward direction relative to the gap between the foam boards 4 at the moment of cutting, thereby achieving a vertical and flat cut of the backing fiber cloth 17 between the two foam boards 4. During this process, the cutting part 15 moves from point A to point B, completing one cutting operation. The first board separates from the second board, and the first board is unloaded by the conveyor belt 6.

[0037] Second path 20 (rapid traverse): After completing the cutting of the first path 19, the control box 1 controls the cutting part 15 to move rapidly along the sliding beam 14 (i.e., the Y-axis direction) to the starting point (i.e. point C) of the third path 21. The return speed is much greater than the feeding speed of the foam board 4 to ensure efficiency.

[0038] Third path 21 (reverse synchronous cutting): When the gap between the second and third boards moves to the cutting area (i.e., point C), a process similar to the first path 19 is repeated, but the sliding beam 14 and the cutting piece 15 move in the opposite direction to the first path 19, i.e., from right to left, while their speed in the Y-axis direction remains synchronized with the feed speed of the foam board 4. The actual movement path of the cutting piece 15 is also a diagonal straight line (third path 21). The cutting piece 15 moves from point C to point D, completing the cutting, separating the second and third boards, and the second board is unloaded.

[0039] Fourth path 22 (fast return): After the cutting is completed, the cut part 15 quickly returns to the initial position (i.e., point A) along the Y-axis, ready for the next loop.

[0040] In summary, the control box 1, through precise control, ensures that the movement trajectory of the cutting piece 15 forms a continuous cycle synchronized with the feed of the foam board 4 (first path 19 → second path 20 → third path 21 → fourth path 22 → first path 19 → ...). First path 19 and third path 21 are effective cutting paths, requiring strict synchronization between the blade and the foam board 4; second path 20 and fourth path 22 are return paths, requiring speed and efficiency. Through this structure, this embodiment achieves automatic, precise, and efficient cutting of the fiber cloth 17 backing between two adjacent foam boards 4 on a continuous production line, completely replacing manual operation.

[0041] To ensure that the cut part 15 can be cut in both the first path 19 and the third path 21, such as Figure 7 As shown, in this embodiment, the cutting component 15 is a double-edged cutting shear. The first path 19 utilizes one of the cutting edges 16 for cutting, and the third path 21 utilizes the other cutting edge 16 for cutting.
