DETAILED DESCRIPTION

[0034] The utility model will be described clearly and completely in combination with examples.

[0035] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the utility model are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0036] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set", "connected", etc. should be understood broadly. For example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or connected through an intermediate medium, or the internal communication of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] Referring to the drawings​Figures 1-10 The diagram shows a seamless winding shaft structure, including a shaft 1, wherein the shaft 1 includes a drive body 2 and a sleeve body 3. In use, the shaft 1 is mounted on the winding machine through the drive body 2, and the winding machine drives the entire shaft 1 to rotate. A limiting sleeve 4 is provided at the joint of the shaft 1 and the drive body 2 and the sleeve body 3.

[0038] The shaft 1 is equipped with a drive mechanism and a support mechanism. The drive mechanism includes a push rod 7, which is inserted into the shaft 1. During use, one end of the push rod 7 is connected to the hydraulic cylinder on the winding machine. The hydraulic cylinder controls the push rod 7 to extend and retract back and forth inside the shaft 1. A drive head 9 is fitted on the other end of the push rod 7. Three drive claws 10 are provided around one end of the drive head 9. A fixing nut 11 is provided at one end of the push rod 7 to fix the drive head 9 and prevent the drive head 9 from slipping off the push rod 7.

[0039] Furthermore, the assembly 3 has a slide groove 12 along its length at the position of the drive head 9. Each slide groove 12 has a pull bar 8, and the pull bar 8 has a first lifting part 81 with a right-angled triangular structure at equal intervals. When in use, the pull bar 8 is driven to slide along the slide groove 12 by the front and rear extension and retraction of the push rod 7.

[0040] The support mechanism includes a first support plate 5 and a second support plate 6, wherein the first support plate 5 and the second support plate 6 are arranged at intervals around the circumference of the suit body 3, and there are three of each. One end of the first support plate 5 and the second support plate 6 is placed inside the limiting sleeve 4. The limiting sleeve 4 is used to limit the radius of the virtual circle in which the first support plate 5 and the second support plate 6 are located when they are opened.

[0041] See appendix Figure 7 As shown, the first support plate 5 has a figure-eight shaped first fitting part 51 on both sides along the length direction, and the second support plate 6 has a second fitting part 61 on both sides that cooperates with the first fitting part 51. The second fitting part 61 overlaps the first fitting part 51.

[0042] The first support plate 5 is symmetrically provided with a second lifting part 52 at the position corresponding to the first lifting part 81. See attached diagram. Figure 9 As shown, when the top rod 7 pulls the pull bar 8 back, the first lifting part 81 acts on the second lifting part 52 to push the first support plate 5 outward. At the same time as the first support plate 5 is pushed outward, the first fitting part 51 acts on the second fitting part 61 to push the second support plate 6 outward simultaneously. This achieves seamless diameter change when the first support plate 5 and the second support plate 6 expand outward, avoiding the problem of gaps forming between the first support plate 5 and the second support plate 6, which cannot provide effective structural support for the paper tube 17.

[0043] Further, the second support plate 6 is provided with a plurality of avoiding blocks 62 equidistantly on one side close to the sleeving body 3, and the sleeving body 3 is provided with avoiding holes 13 corresponding to the positions of the avoiding blocks 62, and the second support plate 6 and the sleeving body 3 are provided with a pullback mechanism through the avoiding holes 13, wherein the pullback mechanism comprises a guide rod 14 and an elastic member 15, one end of the guide rod 14 is connected to the sleeving body 3, the guide rod 14 is sleeved in the elastic member 15, the elastic member 15 is specifically a tension spring, the other end of the guide rod 14 is provided with a limiting ring 16 and is connected with the elastic member 15, and the avoiding blocks 62 are provided with clamping parts for limiting the limiting ring 16, as shown in the accompanying drawings. Figure 8 When the second support plate 6 is lifted up through the first support plate 5, the second support plate 6 will stretch the elastic member 15 through the limiting ring 16, when the jacking rod 7 is extended, the first jacking part 81 removes the jacking effect on the first support plate 5, at this time the second support plate 6 will shrink inward under the reverse pulling force of the elastic member 15, at this time the avoiding blocks 62 will just fall into the avoiding holes 13;

[0044] Therefore, when the first support plate 5 and the second support plate 6 are expanded, the seamless expansion of the first support plate 5 and the second support plate 6 is realized through the cooperation of the jacking rod 7, the pull strip 8, the first jacking part 81 and the second jacking part 52, and then the seamless contraction of the first support plate 5 and the second support plate 6 is realized under the action of the elastic member 15, thereby avoiding the problem that the first support plate 5 and the second support plate 6 cannot support the sleeved paper tube 17 due to the gap generated when the first support plate 5 and the second support plate 6 are expanded;

[0045] Further, in order to make the expansion of the first support plate 5 and the second support plate 6 more smooth and reduce the abrasion between the first jacking part 81 and the second jacking part 52, the first support plate 5 is provided with an oil injection hole 53 at the position of the second jacking part 52, and lubricating oil is injected between the first jacking part 81 and the second jacking part 52 through the oil injection hole 53.

[0046] In use, as shown in the accompanying drawings, Figure 11 Firstly, the jacking rod 7 is extended to drive the pull strip 8 to slide forward along the sliding groove 12, when the pull strip 8 slides forward, the first support plate 5 shrinks inward under the elastic pressure of the second support plate 6, until the radius of the virtual circle where the first support plate 5 and the second support plate 6 are located is smaller than the radius of the paper tube 17, and then the paper tube 17 is sleeved on the first support plate 5 and the second support plate 6, and then the jacking rod 7 is pulled back, at this time the first support plate 5 is linked with the second support plate 6 under the cooperation of the first jacking part 81 and the second jacking part 52, and the first support plate 5 is jacked out, until the side walls of the first support plate 5 and the second support plate 6 completely adhere to the inner wall of the paper tube 17, at this time there is no gap between the first support plate 5 and the second support plate 6, which can effectively support any position inside the paper tube 17, avoid the deformation of the paper tube 17 under the pressure of the aluminum tape, and ensure sufficient strength for the winding of the aluminum tape.

[0047] The above merely describes a preferred embodiment of the present application, and is not intended to limit the protection scope of the present application. Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
