In some embodiments, the flexible composite tube manufacturing apparatus 100 may include a base 110, a spindle 120, and a winding frame 130. The main shaft 120 is rotatably disposed on the base 110, and the winding frame 130 is fixed to the main shaft 120. The base 110 can be used to support the spindle 120 such that the center of rotation of the spindle 120 remains stable when rotated. In some embodiments, the base 110 may support one end of the spindle 120, or the base 110 may support both ends of the spindle 120. In some embodiments, a motor is disposed in the base 110, and the motor may drive the spindle 120 to rotate through a transmission mechanism. The transmission mechanism may include a chain transmission, a belt transmission, a gear transmission, or the like. In some embodiments, the base 110 may be fixed to the ground by casting, or placed on the ground.

In some embodiments, the spindle 120 may include a hollow passage through which a pipe to be wound can pass. The hollow passage may be a through circular hole coaxial with the main shaft 120. The hollow passage of the main shaft 120 can support and limit the portion of the pipe passing therethrough so that the pipe is maintained as tubular as possible. In some embodiments, the conduit passing through the hollow passage may not rotate with the spindle 120 as it rotates about its own axis. In some embodiments, the spindle 120 is removably coupled to the base 110, and the spindle 120 having hollow tubes of different diameters may be replaced as needed to accommodate the manufacture of tubes of different diameters.

In some embodiments, the detachable consumable rack 140 is provided on the winding rack 130, and the consumable rack 140 is used for mounting the strip or wire. The winding frame 130 may be used to support the consumable rack 140. When the spindle 120 rotates, the winding frame 130 can rotate synchronously with the spindle, so as to drive the consumable rack 140 to rotate synchronously with the spindle. In some embodiments, the strip or wire on the consumable rack 140 can be directed to the pipe, and the strip or wire on the consumable rack 140 can be wound onto the pipe surface as the spindle 120 rotates the winding rack 130.

In the working process of the flexible composite pipe manufacturing equipment, a tractor can be used for continuously drawing the pipe to be wound out of the hollow channel at a preset speed. In the process that the pipeline is pulled, the main shaft 120 drives the winding frame 130 and the consumable frame 140 to synchronously rotate, and the strips or wires on the consumable frame 140 can be sequentially wound on the outer surface of the pulled pipeline. In some embodiments, the pipe may be pulled at a constant speed and the spindle 120 may also rotate at a constant speed. In some embodiments, the density of the strip or wire wrap can be controlled by controlling the speed at which the pipe is pulled and/or the rotational speed of the spindle 120. In some embodiments, a certain pressure may be applied to the strip or wire to maintain the strip or wire in a tensioned state so that the strip or wire can be tightly wound around the outer surface of the pipe. In some embodiments, the angle between the strip or wire and the pipe axis may be controlled to adjust the shape of the strip or wire wound on the pipe outer surface. In some embodiments, the angle between the strip or wire and the axis of the pipeline can be 50-60 degrees, and by controlling the angle, the upper layer of material can completely cover the surface of the lower layer, so that high-strength matching between layers is realized, and the strength and toughness of the pipeline are improved.

In some embodiments, the spindle support 150 may be independent of the base 110 (as shown in FIG. 1). In some embodiments, the spindle support 150 may be connected to the base 110 or integrally formed with the base 110, so that the relative position of the spindle support 150 and the base 110 remains stable, and the spindle support 150 and the base 110 can be conveniently installed as a whole.

In some embodiments, the spindle support 150 may be configured to be a set height to maintain the spindle level. In some embodiments, the spindle support 150 may be configured to be liftable. When there is a height difference in the installation site, the heights of both ends of the main shaft 120 can be controlled to be the same by adjusting the height of the main shaft support frame 150. Or the height of the spindle support 150 may be adjusted as desired to change the angle between the center of rotation of the spindle 120 and the horizontal plane. In some embodiments, the spindle support 150 may be designed in a structure with a top end having a smaller area than a bottom end, and a bottom end having a smaller area, so as to maintain stability of the spindle support 150. In some embodiments, the top end of the spindle support 150 may be designed as a semi-cylindrical concave having the same diameter as the spindle 120, and the semi-cylindrical concave is used to limit the spindle 120, so as to prevent the spindle 120 from being separated from the spindle support 150, which is beneficial to further improving the stability of the spindle 120. In some embodiments, at least two rollers, balls or needles may be provided on the top surface of the spindle support frame 150 for supporting the spindle 120. When the spindle 120 rotates, the spindle 120 forms rolling friction with the roller, the ball or the needle roller, and abrasion of the spindle 120 can be reduced.

For another example, the connecting shaft 142 may be disposed within the connecting rod or integrally formed with the connecting rod.

In some embodiments, as shown in fig. 1-3, the winding frame 130 further includes guide wheels 160, which may be provided on the winding frame body 131. The guide wheel 160 may be used to guide the strip 180 to the surface of the pipe 200. The direction of travel of the strip 180 can be controlled by the guide wheel 160, so that the strip 180 can avoid other structures (such as the winding frame body 131, the second flange 134, etc.) on the flexible composite tube manufacturing equipment, and the strip 180 is prevented from interfering with other structures.

The guide wheel 160 will be described in detail with reference to fig. 13. In some embodiments, a plurality of guide wheels 160 may be provided on the winding frame 130. As shown in fig. 13, the guide wheels 160 provided on the winding frame 130 may include a first guide wheel 161, a second guide wheel 162, a third guide wheel 163, and a fourth guide wheel 164.

In some embodiments, the first guide wheel 161 may be used to change the angle at which the strip 180 or wire 190 exits the first guide wheel 161, thereby changing the angle between the strip 180 or wire 190 and the pipe 200. The second guide wheel 162 may be used to change the angle at which the strip 180 or wire 190 is directed to the first guide wheel 161. In some embodiments, the second guide wheel 162 may cooperate with the first guide wheel 161 to provide tension to the strip 180 or wire 190. For example, by setting the spacing and position between the second guide wheel 162 and the first guide wheel 161, the friction of the two against the strip 180 or the wire 190 can be varied to adjust the tension of the strip 180 or the wire 190. In some embodiments, the third guide wheel 163 and the fourth guide wheel 164 may be used to initially guide the ribbon 180 exiting the reel 141 to ensure as smoothness as possible when the ribbon 180 exits the reel 141 to avoid damage to the ribbon 180 or the reel 141.

In some embodiments, as shown in connection with fig. 3 and 13, when the reel 141 is mounted on the winding frame 130, the strip 180 on the reel 141 may sequentially bypass the fourth guide wheel 164, the third guide wheel 163, the second guide wheel 162, and the first guide wheel 161, thereby being wound onto the surface of the pipe 200. In some embodiments, as shown in connection with fig. 9 and 13, when the wire wheel 144 and the wire wheel bracket 143 are mounted on the winding frame 130, the wire 190 on the wire wheel 144 may sequentially bypass the second guide wheel 162 and the first guide wheel 161, thereby being wound to the surface of the pipe 200.

In some embodiments, the first guide wheel 161 may be connected to the winding frame 130 by a telescopic mechanism; and/or the second guide wheel 162 may be connected with the winding frame 130 through the telescopic mechanism 171.

The telescopic mechanism 171 may adjust the distance between the guide wheel 160 (e.g., the first guide wheel 161 and/or the second guide wheel 162) and the winding frame 130 by its own telescopic motion. By adjusting the distance between the first guide wheel 161 and the winding frame 130, the angle of the strip 180 or the wire 190 after leaving the first guide wheel 161 can be changed, thereby adjusting the angle of the strip 180 or the wire 190 with the pipe 200. By adjusting the distance between the second guide wheel 162 and the winding frame 130, the angle at which the strip 180 or the wire 190 is guided to the first guide wheel 161 can be changed. By adjusting the distance between the first guide wheel 161 and/or the second guide wheel 162 and the winding frame 130, the distance and position between the second guide wheel 162 and the first guide wheel 161 can be changed, thereby changing the friction force of the two on the strip 180 or the wire 190 and further adjusting the tension of the strip 180 or the wire 190.

In some embodiments, the rotation angle of the rotation mechanism 172 to the first guide wheel 161 may range between 40 ° and 90 °.

In some embodiments, the rotation axis of the rotation mechanism 172 is parallel to the length direction of the rotation mechanism 172 and perpendicular to the rotation axis of the first guide wheel 161. The first guide wheel 161 may be provided at a free end of the rotation mechanism 172. In some embodiments, the rotating mechanism 172 may be further provided with a locking mechanism, and when the angle of the rotating mechanism 172 is adjusted, the rotating mechanism 172 is locked by using the locking mechanism, so that unnecessary changes of the angle of the first guiding wheel 161 can be avoided. In some embodiments, the rotation mechanism 172 may employ a rotatable damping shaft. Under the action of external force, the damping shaft can rotate, and after the external force is removed, the damping shaft can keep the rotated angle. In some embodiments, the rotation mechanism 172 may include a fixed portion that may be fixedly coupled with the winding frame 130 and a rotating portion rotatably coupled with the fixed portion.

In some embodiments, as shown in connection with fig. 14-15, the first guide wheel 161 may be coupled to the winding frame 130 by a rotation mechanism 172, and the second guide wheel 162 may be coupled to the winding frame 130 by a telescopic mechanism 171, such that the first guide wheel 161 can change angle by the rotation mechanism 172, and the second guide wheel 162 can change distance from the winding frame 130 by the telescopic mechanism.
