[0016] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0017] This application provides a thermoplastic composite molding machine that can perform single-layer, double-layer, and triple-layer composites on different substrates and materials, achieving multiple uses in one machine, effectively improving production efficiency, shortening the length of the production line, reducing the floor space occupied by the production line, and saving costs.

[0018] like Figure 1 As shown, the thermoplastic composite molding machine 100 includes: a frame 10, a preheating mechanism 20, a primary composite mechanism 30, a gap adjustment mechanism 40, a secondary composite mechanism 50, and a control device (not shown in the figure).

[0019] like Figure 1 , 2As shown, the preheating mechanism 20 includes an electromagnetic heating roller 1 extending along its axis in a left-right direction and a pair of water-cooled bearing seats 2 arranged opposite each other on the left and right sides. The pair of water-cooled bearing seats 2 are fixedly installed on the top of the frame 10. After the electromagnetic heating roller 1 is energized, the roller surface temperature rises, which can preheat the high-temperature resistant substrate, allowing the temperature of the high-temperature resistant substrate to rise rapidly to the process temperature, thereby strengthening its bonding strength with the composite layer. A temperature control probe (not shown in the figure) connected to the control device is provided at the electromagnetic heating roller 1. The temperature control probe is used to detect the roller surface temperature of the electromagnetic heating roller 1 and transmits the detected temperature to the control device in real time. The control device is connected to the electromagnetic heating roller 1 and can control the temperature of the electromagnetic heating roller 1 based on the roller surface temperature transmitted by the temperature control probe to ensure that the roller surface temperature of the electromagnetic heating roller 1 is maintained within the required process temperature range.

[0020] Each water-cooled bearing housing 2 is equipped with a bearing, and the two ends of the electromagnetic heating roller 1 are respectively inserted into the bearings of a pair of water-cooled bearing housings 2, so that it can be rotatably mounted on the frame around its own axis.

[0021] like Figure 3 As shown, each of the pair of water-cooled bearing housings 2 has a water-cooling channel for cooling water to pass through. Each water-cooled bearing housing 2 includes an upper bearing housing 21 and a lower bearing housing 22 that cooperate with each other. The water-cooling channel includes a first flow channel 23 on the upper bearing housing 21 and a second flow channel 24 on the lower bearing housing 22. The first flow channel 23 and the second flow channel 24 are independent of each other. The first flow channel 23 has a first inlet 231 and a first outlet 232 on the upper bearing housing 21. The second flow channel 24 has a second inlet 241 and a second outlet 242 on the lower bearing housing 22. The first inlet 231, the first outlet 232, the second inlet 241 and the second outlet 242 are all connected to an external water-cooling source. The water-cooling source supplies cooling water to the upper bearing housing 21 and the lower bearing housing 22 through the first inlet 231 and the second inlet 241. After passing through the first flow channel 23 and the second flow channel 24, the cooling water is discharged from the water-cooled bearing housing 2 through the first outlet 232 and the second outlet 242. Cooling water cools the water-cooled bearing housing 2 and the bearing installed inside the water-cooled bearing housing 2, preventing the high temperature of the electromagnetic heating roller 1 from damaging the bearing and extending the service life of the bearing.

[0022] The water-cooled bearing housing 2 has a bearing cavity 25 for accommodating the bearing. A first flow channel 23 and a second flow channel 24 surround the bearing cavity 25 to improve the cooling efficiency and cooling effect of the bearing inside the bearing cavity 25.

[0023] like Figure 1 , 2 As shown, the primary composite mechanism 30 includes a first composite roller 3 parallel to the electromagnetic heating roller 1 and located behind the electromagnetic heating roller 1, and a first opening and closing assembly 4 connected to the first composite roller 3 in a transmission manner. The first opening and closing assembly 4 is used to drive the first composite roller 3 to move back and forth in the front-back direction.

[0024] The first opening and closing assembly 4 includes a pair of first sliding bearing seats 41 arranged opposite each other on the left and right and a pair of first opening and closing cylinders 42. Each first opening and closing cylinder 42 is drivenly connected to the first sliding bearing seat 41 on the corresponding side to drive the first sliding bearing seat 41 to move relative to the frame 10 in the front-back direction. The two ends of the first composite roller 3 are respectively engaged with the pair of first sliding bearing seats 41. The first composite roller 3 is mounted on the frame 10 so that it can rotate around its own axis and move in the front-back direction through the pair of first sliding bearing seats 41.

[0025] A pair of first opening and closing hydraulic cylinders 42 are signal-connected to the control device to drive the first sliding bearing seat 41 to move under the command of the control device, thereby driving the first composite roller 3 to move closer to or away from the electromagnetic heating roller 1.

[0026] A gap adjustment mechanism 40 is installed between the electromagnetic heating roller 1 and the first composite roller 3. The gap adjustment mechanism 40 is used to adjust the size of the roller surface gap between the electromagnetic heating roller 1 and the first composite roller 3. The gap adjustment mechanism 40 includes a fine adjuster 401, a top block 402, and an adjusting screw 403. The fine adjuster 401 is installed on the water-cooled bearing seat 2, the top block 402 is installed on the first sliding bearing seat 41, and the adjusting screw 403 is connected to the fine adjuster 401. When the operator rotates the adjusting screw 403, the fine adjuster 401 and the top block 402 cooperate to fine adjust the roller surface gap between the electromagnetic heating roller 1 and the first composite roller 3, and precisely control the size of the roller surface gap, thereby enabling precise control of the thickness of the sheet laminated between the electromagnetic heating roller 1 and the first composite roller 3.

[0027] The secondary composite mechanism 50 is located behind the first composite roller 3 and includes a second composite roller 5 and a third composite roller 6 arranged vertically opposite each other, and a second opening and closing assembly 7 that is drively connected to the third composite roller 6. Both the second composite roller 5 and the third composite roller 6 are parallel to the electromagnetic heating roller 1 and can be rotatably mounted on the frame 10 around their own axis. The second opening and closing assembly 7 is used to drive the third composite roller 6 to move back and forth in the vertical direction to move closer to or away from the second composite roller 5.

[0028] The second opening / closing assembly 7 includes a pair of second sliding bearing seats 71 arranged opposite each other, a pair of fixed bearing seats 72 arranged opposite each other, and a pair of second opening / closing cylinders 73. Each second opening / closing cylinder 73 is drivenly connected to the second sliding bearing seat 71 on the corresponding side to drive the second sliding bearing seat 71 to move back and forth in the vertical direction relative to the frame 10. The two ends of the second composite roller 5 are respectively engaged with the pair of fixed bearing seats 72, which are fixedly mounted on the frame 10. The second composite roller 5 is rotatably mounted on the frame 10 around its own axis via the pair of fixed bearing seats 72. The two ends of the third composite roller 6 are respectively engaged with the pair of second sliding bearing seats 71, and it is mounted on the frame 10 so that it can both rotate around its own axis and move vertically via the pair of second sliding bearing seats 71. A pair of second opening and closing hydraulic cylinders 73 are connected to the control device via signal, and drive the third composite roller 6 to move closer to or away from the second composite roller 5 under the command of the control device.

[0029] A pressure digital display (not shown in the figure) is installed between the second composite roller 5 and the third composite roller 6 and is connected to the control device. The pressure digital display is used to detect the pressure between the second composite roller 5 and the third composite roller 6 in real time and feed the detected pressure back to the control device. The control device controls the operation of the second opening and closing cylinder 73 according to the feedback pressure, thereby accurately controlling the gap between the second composite roller 5 and the third composite roller 6.

[0030] The thermoplastic composite molding machine 100 also includes four servo motors 60, which are connected to the control device. The four servo motors 60 are respectively connected to the electromagnetic heating roller 1, the first composite roller 3, the second composite roller 5, and the third composite roller 6. Under the control of the control device, the corresponding rollers are synchronously driven to rotate around their own axis, and the electromagnetic heating roller 1, the first composite roller 3, the second composite roller 5, and the third composite roller 6 rotate at the same linear speed to ensure constant tension conveying of the composite sheet.

[0031] A guide roller 8 is provided on the front side of the gap between the second composite roller 5 and the third composite roller 6. The guide roller 8 is rotatably mounted on the frame 10 around its own axis and is parallel to the electromagnetic heating roller 1. The guide roller 8 is used to guide the upstream conveyed sheet to the gap between the second composite roller 5 and the third composite roller 6, to guide the conveyed sheet and prevent the sheet from being damaged.

[0032] A moving mechanism 70 is provided at the bottom of the frame 10. The moving mechanism 70 includes a moving guide rail 11 extending in the front-to-back direction, a plurality of moving wheels 12 rotatably mounted on the frame 10, and a drive motor 13 that is pulsatorically connected to the moving wheels 12. The moving wheels 12 cooperate with the moving guide rail 11 to roll back and forth along the moving guide rail 11. The drive motor 13 drives the moving wheels 12 to roll, so that the moving mechanism 70 can drive the frame 10 and the mechanism mounted on the frame 10 to move back and forth in the front-to-back direction. The moving mechanism 70 adjusts the position of the thermoplastic composite molding machine 100 below the extrusion die according to different composite conditions.

[0033] like Figure 1 As shown, during the high-temperature resistant substrate lamination process, the substrate is unwound and pulled to the thermoplastic composite molding machine 100 by the front unwinding mechanism. The substrate is rapidly heated to the process temperature by the electromagnetic heating roller. The extruder above the thermoplastic composite molding machine 100 extrudes the material flow downwards, which is poured onto the substrate. Simultaneously, the first composite roller 3 and the electromagnetic heating roller 1 press together to perform a first lamination. After the first lamination, the sheet is guided by the guide roller 8 and enters between the second composite roller 5 and the third composite roller 6. The third composite roller 6 presses together with the second composite roller 5 to perform a second lamination, increasing the lamination strength and leveling the sheet after the second lamination. At the same time, the pressure digital display between the second composite roller 5 and the third composite roller 6 provides real-time feedback to the control device on the pressure between the two rollers. The control device controls the second opening and closing cylinder 73 to adjust the gap between the second composite roller 5 and the third composite roller 6 based on the feedback pressure.

[0034] After being preheated by the electromagnetic heating roller, the high-temperature resistant substrate can enhance the composite strength with the composite layer. The two-stage composite process of the thermoplastic composite molding machine 100 further enhances the composite strength and flatness, effectively reducing production steps and the floor space occupied by the equipment.

[0035] like Figure 4 As shown, during single-layer coating, the electromagnetic heating roller 1 and the first composite roller 3 are separated, and the extruder above extrudes the material flow downwards. The material flow directly coats the surface of the first composite roller 3, and is then transported via the guide roller 8 to the space between the second composite roller 5 and the third composite roller 6. The second composite roller 5 and the third composite roller 6 press together to flatten and shape the sheet. At the same time, the pressure digital display between the second composite roller 5 and the third composite roller 6 provides real-time feedback to the control device on the pressure between the two rollers. The control device controls the second opening and closing cylinder 73 to adjust the gap between the second composite roller 5 and the third composite roller 6 based on the feedback pressure.

[0036] like Figure 5As shown, during the three-layer composite process, the substrate and the first composite sheet are composited once between the electromagnetic heating roller 1 and the first composite roller 3. The sheet after the first composite and the second composite sheet are composited a second time between the second composite roller 5 and the third composite roller 6. At this time, the substrate, the first composite sheet and the second composite sheet are composited into a three-layer sheet.

[0037] This application enables the composite of different substrates and materials into single-layer, double-layer, and triple-layer composites using a single thermoplastic composite molding machine 100, reducing manufacturers' investment in different types of composite equipment, saving production costs, and reducing the floor space required for the production line.
