[0070] The consolidation device 130 is composed of a plurality of consolidation units 140. The plurality of consolidation units 140 are arranged in a ring around the traveling direction of the thermoplastic composite pipe 10, so that a composite channel 131 as described above is formed at the center of the ring. Among them, the length direction of the consolidation unit 140 is the traveling direction of the thermoplastic composite pipe 10. Refer to Figure 3 and Figure 9 , a plurality of support teeth 123 are provided on the inner side of the support ring 122. The plurality of support teeth 123 are arranged at intervals along the circumferential direction of the support ring 122. The consolidation unit 140 is arranged between two adjacent support teeth 123. In other words, the support teeth 123 form a pair to clamp and fix the consolidation unit 140.
[0071] Refer to Figure 5 and Figure 6 , the consolidation unit 140 includes two side plates 141, and the two side plates 141 are arranged at intervals. At least two guide rollers 147 are arranged between the two side plates 141, and the guide rollers 147 are rotatably connected between the two side plates 141.

The side of the ring-shaped flexible belt 148 opposite to the contact surface of the temperature control device 144 and the ring-shaped flexible belt 148 is configured as a pressing surface 151. The ring-shaped flexible belt 148 can be a steel belt, a belt, a nylon belt, a rubber belt, a polyvinyl chloride belt, etc. Exemplarily, the ring-shaped flexible belt 148 in this embodiment is a steel belt.
[0072] For example Figure 6The shown setting has four guide rollers 147, which are divided into two first guide rollers 147A and two second guide rollers 147B. Among them, the connection line between the axes of the two first guide rollers 147A is parallel to the central axis of the composite channel 131. The two second guide rollers 147B are arranged at intervals from the two first guide rollers 147A, and the connection line between the two second guide rollers 147B is offset from the connection line between the two first guide rollers 147A along the width direction of the consolidation unit 140. As a preferred embodiment, the connection line between the two second guide rollers 147B is parallel to the connection line between the two first guide rollers 147A. It can be understood that the second guide roller 147B can function as a tensioning roller. The pressing surface 151 is located between the contact portions of the annular flexible belt 148 and the two first guide rollers 147A. The first guide roller 147A and the second guide roller 147B are radially spaced apart from the composite channel 131, and the distance between the two first guide rollers 147A is greater than the distance between the two second guide rollers 147B.
[0073] Reference Figure 6 , the temperature adjusting device 144 includes a heating part 145 and a cooling part 146. The heating part 145 and the cooling part 146 are in contact with the annular flexible belt 148. Among them, the side surface of the annular flexible belt 148 that is opposite to the contact surface between the heating part 145 and the annular flexible belt 148 is constructed as a hot pressing surface 151A, and the side surface of the annular flexible belt 148 that is opposite to the contact surface between the cooling part 146 and the annular flexible belt 148 is constructed as a cold pressing surface 151B.

As a form of implementation, the heating part 145 and the cooling part 146 can be constructed as plate-shaped and clamped between two side plates 141, and they are separated by a heat insulation plate 150 therebetween.
[0075] The consolidation unit 140 further includes a first driving device 149. The first driving device 149 is arranged on the side plate 141, and the output shaft of the first driving device 149 is connected to one of at least two guide rollers 147.

For example Figure 5 and Figure 6 as shown, the output shaft of the first driving device 149 can be connected to the second guide roller 147B. The first driving device 149 can be a driving motor.
[0076] The consolidation unit 140 further includes a fixing plate 142, which is connected between the two side plates 141 and is fixed relative to the side plates 141. The position of the temperature regulating device 144 can be changed relative to the side plates 141. Specifically, an elastic member 143 is connected between the fixing plate 142 and the temperature regulating device 144. The elastic member 143 is used to apply an elastic force towards the pressing surface 151 to the temperature regulating device 144, so that the temperature regulating device 144 can continuously extrude the annular flexible belt 148, and then the pressing surface 151 of the annular flexible belt 148 can continuously apply pressure to the thermoplastic composite pipe 10. Thus, the thermoplastic composite pipe 10 can be heated and melted and cooled and consolidated under continuous pressure, making the composite bonding of the winding layer more firm. The elastic member 143 can be a spring or a rubber member, etc. In this embodiment, the elastic member 143 is configured as a compression spring.
[0077] As an implementation form, the composite device 100 further has a rotating assembly, and the rotating assembly can act on the consolidation device 130 to enable the consolidation device 130 to rotate axially. Such rotation can, for example, stagger the adjacent consolidation units by rotation when two or more composite devices are used in combination, so that the downstream pressing surface is staggered from the upstream pressing surface, improving the uniformity of pipe composite and also avoiding pressing ridges on the pipe.
[0078] Specifically, referring to Figure 7 、 Figure 8 and Figure 9 , the frame 120 is further provided with a bearing 125. The outer ring of the bearing 125 is connected to the periphery of the through hole 121, and the inner ring of the bearing 125 is connected to the support ring 122, so that the support ring 122 can rotate relative to the frame 120, and thus the support ring 122 drives the consolidation device 130 to rotate together.
[0079] The rotating assembly includes a transmission device 124 and a second driving device 126. The transmission device 124 is connected to the outer periphery of the support ring 122. The second driving device 126 is disposed on the base 110, and the output shaft of the second driving device 126 is connected to the rotating shaft of the transmission device 124, so that the transmission device 124 can rotate under the drive of the second driving device 126, and then drive the support ring 122 and the consolidation device 130 on the support ring 122 to rotate synchronously.
[0080] As an implementation form, the transmission device 124 can be an annular member with a toothed structure on its outer periphery. The output end 127 of the second driving device 126 has a toothed portion, and the toothed portion is meshed and linked with the toothed structure of the transmission device 124. As an example, the second driving device 126 can be a servo motor.
[0081] The second aspect of the present application provides a production system. The production system includes at least two composite devices 100 of the first aspect described above. The at least two composite devices 100 are arranged in series, and along the traveling direction of the thermoplastic composite pipe 10, the projections of the consolidation units 140 of the at least two composite devices 100 on the radial section of the consolidation device 130 do not overlap. Specifically, by adjusting the rotation angle of the output end 127 of the second driving device 126 on the two composite devices 100, the consolidation units 140 of the two composite devices 100 are staggered along the conveying direction of the pipe material.
[0082] According to the production system of the present application, more than two composite devices 100 are used in combination, and the consolidation units 140 are staggered, which further improves the uniformity of pipe material composite and can also avoid pressing out ridge lines on the pipe material.
