[0032] like Figures 1-12 The bellows winding drum shown includes a generally cylindrical inner cylinder 5, which is hollow and has a first chuck 1 and a second chuck 2 fixedly connected to both ends. The distance between the first chuck 1 and the second chuck 2 is uniform and is usually 1.1 to 1.25 times the maximum outer diameter of the bellows. The inner wall of the inner cylinder 5 has a protruding inner clamping plate 501. One end face of the first chuck 1 has a rear clamping ring 106, which fits perfectly into the inner cylinder 5. The edge of the rear clamping ring 106 has a rear clamping groove 107 for engaging with the inner clamping plate 501. On the other hand, one end of the second chuck 2 also has a front clamping ring 201 with the same structure as the rear clamping ring 106, which fits perfectly into the inner cylinder 5. The edge of the front clamping ring 201 has a front clamping groove 202 for engaging with the inner clamping plate 501. In this way, the first chuck 1 and the second chuck 2 cannot rotate relative to the inner cylinder 5.

[0033] In order for the winding drum to obtain power from the output end of the drive mechanism, the other end of the first chuck 1 facing away from the inner cylinder 5 has a coaxial end shaft 101. The end of the end shaft 101 has a connecting plate 102 with a larger diameter. The connecting plate 102 has a connecting hole 105 located outside the end shaft 101. There are several connecting holes 105, which are equidistantly arranged around the axis of the end shaft 101, for bolts and other connecting parts to pass through and fix the connecting plate 102 to the output end of the drive mechanism.

[0034] The coaxial spline shaft 103 is fixedly connected to the center of the first chuck 1, and the through spline hole 203 is formed in the center of the second chuck 2. The end of the spline shaft 103 is fixedly connected to the limiting cover 3 through the constraint part 4 and the spline hole 203. Specifically, the limiting cover 3 includes a central disc 301, the edge of the disc 301 has a pressing ring 302, the end surface of the pressing ring 302 directly contacts the end surface of the second chuck 2, and the disc 301 is opposite to the end surface of the second chuck 2 and is provided with a spline groove 304, which is inserted into the end of the spline shaft 103. The end surface of the disc 301 away from the second chuck 2 is provided with a through hole 303 communicating with the spline groove 304. The end of the spline shaft 103 is provided with an internal screw hole 104. The specific structure of the constraint part 4 includes a screw rod 401, which is screwed into the internal screw hole 104 through the through hole 303. One end of the screw rod 401 has an end cap 402, which is usually a regular hexagonal prism, facilitating engagement with a wrench tool to achieve convenient disassembly and assembly.

[0035] The inner cylinder 5 is provided with a recess groove 502 extending inwardly to the inside of the clamping plate 501, which can accommodate the end of the corrugated pipe. The inner wall of the recess groove 502 has an embedded cylinder 503, the end of the corrugated pipe is sleeved outside the embedded cylinder 503, the embedded cylinder 503 is completely located in the recess groove 502, and the farthest end of the embedded cylinder 503 does not exceed the range surrounded by the recess groove 502. The axis of the embedded cylinder 503 is perpendicular to the axis of the inner cylinder 5, the extension direction of the embedded cylinder 503 is parallel to the tangent line of the connecting line of the center of the front clamping ring 201 and the embedded cylinder 503 at the edge of the front clamping ring 201, so that the corrugated pipe beyond the recess groove 502 can continue to extend along the tangent direction of the embedded cylinder 503. The outer side of the embedded cylinder 503 is provided with a friction groove 504, which is annular and collinear with the axis of the embedded cylinder 503, can increase the contact friction force between the embedded cylinder and the end of the corrugated pipe, and can reduce the probability of loosening.

[0036] Working principle: when in use, the end of the corrugated pipe is sleeved outside the embedded cylinder 503, and then the driver drives the winding drum to rotate the inner cylinder 5 in the direction opposite to the extension direction of the embedded cylinder 503, so that the corrugated pipe can be smoothly wound outside the inner cylinder 5, until the subsequent wound corrugated pipe presses the end of the corrugated pipe inserted into the embedded cylinder 503, so as to increase the winding force, and the stacked corrugated pipes can be further pressed tightly and will not loosen.

[0037] The foregoing describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-described embodiments, and the above-described embodiments and descriptions in the specification are only the principles of the present application.
