[0028] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only a part of the embodiments of the present application, not all the embodiments.

[0030] Combination Figure 1 And Figure 2 As shown in the drawings, the production equipment of the pultruded plate provided by the embodiment of the present application includes a pultruded plate production device 1, a winding device 2, a cutting device 3 and an online detection device 4.

[0031] The pultrusion plate production device 1 is used for producing the pultrusion plate 5. The winding device 2 is used for winding the pultrusion plate 5 output by the pultrusion plate production device 1. The cutting device 3 is arranged between the pultrusion plate production device 1 and the winding device 2 and is used for cutting the pultrusion plate 5. The pultrusion plate production device 1 can be a conventional device used for producing the pultrusion plate 5. The winding device 2 can also be a conventional device used for winding the pultrusion plate 5 and is connected with the output end of the pultrusion plate 5 to wind the pultrusion plate 5 output by the pultrusion plate production device 1 in a rotating state. The cutting device 3 can also be a conventional device used for cutting the pultrusion plate 5. When the length of the pultrusion plate 5 wound on the winding device 2 reaches the design requirement, the pultrusion plate 5 is cut by the cutting device 3 to disconnect the production line, the winding disc on the winding device 2 is replaced, and the winding of the pultrusion plate 5 is continued. That is, the pultrusion plate production device 1, the winding device 2 and the cutting device 3 are not limited in the present application and are not the protection points of the present application.

[0032] The online detection device 4 is arranged between the pultrusion plate production device 1 and the cutting device 3. The online detection device 4 includes a rack 41 and a detection member 42 arranged on the rack 41. The detection member 42 is electrically connected with a controller, so that the detection member 42 can feed back the detection result to the controller. The detection member 42 is used for detecting whether the passing pultrusion plate 5 has defects. The controller can change the working parameters of the pultrusion plate production device 1 according to the detection result of the detection member 42, so that the pultrusion plate 5 output by the pultrusion plate production device 1 meets the design requirement. The working parameters include the shutdown of the pultrusion plate production device 1, the conveying speed of the pultrusion plate 5, the fiber content in the raw material, the working temperature, etc. The cutting device 3 can cut the defective part of the pultrusion plate 5 during the running of the pultrusion plate 5, so as to avoid that the pultrusion plate 5 with defects is mixed into the qualified products.

[0033] The working process of the pultrusion plate production equipment of the present application is as follows:

[0034] The pultrusion plate production device 1 produces the pultrusion plate 5 and continuously conveys the produced pultrusion plate 5 towards the winding device 2. The end of the pultrusion plate 5 is connected with the winding disc on the winding device 2, so that the pultrusion plate 5 is wound on the winding disc under the rotation of the winding disc and the conveying action of the pultrusion plate production device 1. When the pultrusion plate 5 wound on the winding disc reaches the preset size, the cutting device 3 works to cut the pultrusion plate 5 at the cutting position. The winding disc continues to wind until the disconnected pultrusion plate 5 is completely wound, and the empty winding disc is replaced. The pultrusion plate 5 is continuously produced and conveyed towards the winding device 2. At this time, the disconnected end of the pultrusion plate 5 can be manually introduced into the new winding disc, and the pultrusion plate 5 is continuously wound by the winding disc.

[0035] The online detection device 4 detects the quality of the pultruded plate 5 in real time during the winding process. When the online detection device 4 detects a defect in the pultruded plate 5, the online detection device 4 feeds back the detected defect information to the controller. The controller analyzes the cause of the defect according to the received defect information and changes the corresponding working parameters of the pultruded plate production device 1, so that the pultruded plate 5 produced by the pultruded plate production device 1 meets the requirements. At the same time, the controller controls the cutting time of the cutting device 3 according to the defect information to cut off the part of the pultruded plate 5 with defects. For example, when the defective part is a small section, the controller can calculate the time when the pultruded plate 5 moves to the position of the cutting device 3 according to the conveying speed of the pultruded plate 5, so that the cutting device 3 cuts the pultruded plate 5 for the first time at the front end of the defect position, and cuts the pultruded plate 5 for the second time when the tail end of the pultruded plate 5 with defects moves to the side of the cutting device 3 away from the online detection device 4, so as to cut off the defective part of the pultruded plate 5. The cutting device 3 cuts off the pultruded plate 5 at 300 mm away from both ends of the defective part of the pultruded plate 5, ensuring that the pultruded plate 5 wound by the winding device 2 completely meets the production requirements. At this time, a new winding disc is replaced, and the worker stretches the end of the qualified pultruded plate 5 into the winding disc to be wound by the winding disc, and continues the corresponding work. When the defective part is a large section, the controller can send a stop working signal, and the pultruded plate production device 1 stops producing the pultruded plate 5 after receiving the stop working signal, avoiding further waste of materials.

[0036] For example, when a crack is detected on the surface of the pultruded plate 5, the controller can analyze the cause of the crack according to the different types of cracks (length, depth, gap of the crack, etc.). For example, the production speed is too fast, and the product cannot be fully solidified; for example, the working temperature is too low, causing the product to shrink too fast; or the fiber content is too low. The controller can send a signal to adjust the corresponding working parameters according to the corresponding type of crack, such as sending a signal to the pultruded plate production device 1 to reduce the production speed or increase the feeding end temperature, increase the post-solidification temperature, and as much as possible control the resin content under the condition that the process allows. The pultruded plate production device changes the corresponding parameters after receiving the corresponding adjustment signal, so that the pultruded plate 5 produced meets the requirements.

[0037] For another example, when a blue stripe-shaped color difference is detected on the surface of the pultruded plate 5, it is identified that the defect is rich in resin, and the controller can analyze the cause of the rich resin: including uneven distribution of fibers and solidified glue blocks at the inlet of the mold (the orientation of the fibers is changed when the fibers enter the mold, causing the local fiber content to be low, and then causing the rich resin to appear). At this time, the controller can send a stop working signal according to the obtained defect information, and the pultruded plate production device 1 stops working after receiving the stop working signal. The worker can perform corresponding work to eliminate the defect.

[0038] Of course, there are many types of defects of the pultrusion plate 5, the controller can identify the type of defect according to the specific defect characteristics and analyze the cause, and further give the solution, which is not described one by one here.

[0039] The controller can obtain the cause of the defect in various ways according to the detected defect type, for example, the controller can be inputted with the conventional defect type and the cause of the type of defect. Further, when the controller receives the defect type fed back by the online detection device 4, the cause of the type of defect can be obtained to issue corresponding work instructions to adjust the working parameters of the pultrusion plate production device 1. This comparison method is a conventional technology, and therefore, it is not described in detail here. In addition, the controller can also determine whether the part of the pultrusion plate 5 needs to be cut off according to the type and degree of the defect to avoid waste of the pultrusion plate 5.

[0040] The production equipment of the pultrusion plate 5 provided by the application includes an online detection device 4, which can detect the defect of the pultrusion plate 5 in real time through the online detection device 4, which includes real-time detection of surface defects of the pultrusion plate 5 and can immediately and continuously detect internal defects of the pultrusion plate 5 that cannot be seen by the naked eye, and the working parameters of the pultrusion plate production device 1 are adjusted by the controller according to the detection results to avoid producing a large number of defective products, save material cost, and the detection method does not require manual intervention, which reduces labor cost, and the detection process does not need to stop, which avoids affecting the production efficiency.

[0041] In some other embodiments, as shown in Figure 2 The online detection device 4 further includes a code spraying member 43 for marking the defect position of the pultrusion plate 5. In this design, the code spraying member 43 marks the defect position of the pultrusion plate 5, which facilitates the workers to accurately find the defect position of the pultrusion plate 5 to detect the irregular defects and quickly analyze the defect causes.

[0042] Further optimization, the code spraying member 43 is arranged on one side of the detection member 42 facing the moving direction of the pultrusion plate 5. In this design, the detection member 42 can detect the pultrusion plate 5 during movement, and when the detection member 42 detects that the corresponding position of the pultrusion plate 5 has a defect, the pultrusion plate 5 continues to move forward to the position of the code spraying member 43, and then the code spraying member 43 can mark the defect position.

[0043] Further optimization, the code spraying member 43 is above the pultrusion plate 5 to spray the mark above the pultrusion plate 5, which is convenient for the workers to observe.

[0044] As shown in Figure 2As shown, the rack 41 is provided with an opening 411 through which the pultrusion plate 5 can pass. In this design, the pultrusion plate 5 can pass from the rack 41 to ensure that the pultrusion plate 5 is conveyed in a straight line, ensuring the conveying effect.

[0045] In some embodiments, the detection member 42 comprises an ultrasonic phased array detection device, and the pultrusion plate 5 passes through the ultrasonic phased array detection device to enable detection of the pultrusion plate 5 by the ultrasonic phased array detection device. The ultrasonic phased array technology is a mature technology, and the pultrusion plate 5 can be detected by the ultrasonic phased array detection device, which is not described in detail here. It can be understood that the detection member 42 can also use other devices that can detect surface defects and internal defects of the pultrusion plate 5.

[0046] The pultrusion plate 5 production equipment of the present application also comprises a display terminal for presenting the detection results of the detection member 42. So that the staff can intuitively understand the production situation of the pultrusion plate 5, and make corresponding preparations. In addition, the defect types of the pultrusion plate 5 detected by the online detection device 4 and the defect output reasons obtained by the controller can be presented on the display terminal to facilitate the staff to understand the production situation.

[0047] The display terminal can also present the working parameters of the pultrusion plate production device 1 and can operate the display terminal to adjust the working parameters of the pultrusion plate production device 1. Further, the working parameters of the pultrusion plate production device 1 can be actively adjusted through the display terminal, so that the production of the pultrusion plate 5 meets the demand, and the convenience of operation is increased.

[0048] As shown in Figure 1 The pultrusion plate production device 1 comprises a traction machine 11, and the online detection device 4 is arranged between the traction machine 11 and the cutting device 3. The traction machine 11 can convey the pultrusion plate 5 produced by the pultrusion plate production device 1 towards the direction of the winding device 2, so that after the pultrusion plate 5 is cut by the cutting device 3, the traction machine 11 can continue to convey the pultrusion plate 5 towards the direction of the winding device 2, so that the free end of the pultrusion plate 5 can be wound on the winding disc of the winding device 2, and the winding operation can continue.
