Description
Technical Field
[0001] This utility model belongs to the field of coil technology, specifically relating to a coil device for interconnecting the ends of tube segments. Background Technology
[0002] Roll materials are used in a wide range of fields, such as die-cutting, slitting, laminating, rewinding, printing, bonding, labeling, winding, automatic packaging sealing, and sealing equipment for milk tea machines, all of which require the collection of rolled edges or waste. Currently, in production, paper tubes or plastic tubes are used to collect rolled edge waste, which is then wrapped around the tubes. However, this method makes it inconvenient to separate the rolled edge waste, affecting its secondary utilization and resulting in resource waste.
[0003] In the prior art, CN111517172B discloses an expansion device. In this design, the expansion tube body includes two or more arc-shaped components, and the positioning of the expansion tube body during expansion and contraction is achieved between adjacent arc-shaped components through movable blocks and movable grooves. In actual production, as the number of arc-shaped components increases, the width of the arc-shaped components also becomes narrower. Furthermore, the movable groove, being a through-groove structure, affects the structural strength of the arc-shaped components.
[0004] Therefore, it is necessary to design a segment end interconnection winding device that has reliable structural strength and can achieve limiting. Utility Model Content
[0005] To address the aforementioned problems in the existing technology, this solution provides a segment end interconnection type winding device.
[0006] The technical solution adopted in this utility model is as follows:
[0007] A segment end interconnection type winding device, comprising:
[0008] Central axis;
[0009] The fixed truncated cone is coaxially fixed on the central axis;
[0010] The movable cone is coaxially mounted on the central axis and can slide along the central axis, with the small end of the movable cone facing the small end of the fixed cone.
[0011] The unit tube segment has one end abutting against the conical surface of the intermediate truncated cone and the other end abutting against the conical surface of the movable truncated cone; both ends of the unit tube segment are provided with interconnecting hooks and interconnecting grooves; the interconnecting hooks extend laterally into the interconnecting grooves of adjacent unit tube segments; the interconnecting hooks can move in the interconnecting grooves to change the distance between adjacent unit tube segments; several unit tube segments are arranged in a ring around the central axis.
[0012] The elastic ring connects all the unit segments and brings them together towards the central axis.
[0013] As an alternative or supplement to the above structure: the interconnecting hook is L-shaped or T-shaped, and the shape of the interconnecting groove matches the interconnecting hook and its movement path.
[0014] As an alternative or supplement to the above structure: the unit tube is an integrally formed structure and is elongated; the interconnecting hook is integrally connected to the unit tube, the interconnecting hook is located at the end edge of the unit tube and extends to the end of the adjacent unit tube.
[0015] As an alternative or supplement to the above structure: the interconnecting groove is a groove structure formed on the end face of the unit tube segment.
[0016] As an alternative or supplement to the above structure: the interconnecting hook is L-shaped, the interconnecting hook includes a hook head and a hook shank, the hook head is connected to the end of the hook shank away from the unit tube segment, and the hook shank is arc-shaped.
[0017] As an alternative or supplement to the above structure: the unit segment is a multi-component combination structure, including a long strip-shaped segment body, with end connecting blocks detachably connected to both ends of the segment body, the interconnecting hook is located on the side of the end connecting block, and the two are integrated, with the interconnecting hook extending to the end connecting block of the adjacent unit segment.
[0018] As an alternative or supplement to the above structure: the interconnecting groove is a groove structure formed on the end face of the end connecting block, and the interconnecting groove is located at the end of the end connecting block facing the tube body.
[0019] As an alternative or supplement to the above structure: the interconnecting hook is T-shaped, the interconnecting hook includes a hook head and a hook shank, the hook head is connected to the end of the hook shank away from the unit tube segment, and the hook shank is arc-shaped.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. In this solution, since the interconnecting grooves and interconnecting hooks are located at the ends of the unit tube segments, they will not form through grooves on the unit tube segments. Even when the number of unit tube segments increases and the width becomes narrower, the structural strength of the unit tube segments can still be guaranteed. At the same time, the mutual cooperation of the interconnecting grooves and interconnecting hooks can also be used to achieve limiting.
[0022] 2. At the same time, since the interconnecting grooves and interconnecting hooks are located at the ends of the unit segments, the assembly difficulty when connecting the interconnecting grooves and interconnecting hooks is reduced. No through grooves are set on the unit segments, which effectively ensures the structural strength when the unit segments are made of aluminum alloy or plastic materials. Attached Figure Description

[0030] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.
[0031] Example 1
[0032] like Figures 1 to 2 As shown, this embodiment designs a segment end interconnected winding device, including a central shaft 1, a movable cone 2, a unit segment 3, a fixed cone 4, an elastic ring, and other components.
[0033] The central shaft 1 adopts a circular long rod structure, and keyways can be set on the side wall of the central shaft 1. The central shaft 1 can be a solid shaft or a hollow tube.
[0034] The fixed cone 4 has a conical structure. Several grooves are provided on the conical surface of the fixed cone 4. The extension line of the grooves is located on the center line of the fixed cone 4. The number of grooves is equal to or less than the number of unit tube segments 3. The small end of the fixed cone 4 faces the unit tube segment 3. The fixed cone 4 is coaxially fixed on the central shaft 1. The fixed cone 4 can be fixed by key connection.
[0035] The movable cone 2 has a conical structure and is coaxially mounted on the central axis 1. It can slide along the central axis 1. Several grooves are provided on the conical surface of the movable cone 2. The extension line of the grooves is located on the center line of the movable cone 2. The number of grooves is equal to or less than the number of unit tube segments 3. The small end of the movable cone 2 faces the unit tube segment 3, that is, the small end of the movable cone 2 faces the small end of the fixed cone 4.
[0036] Each unit segment 3 is elongated, and several unit segments 3 are arranged around the outer periphery of the central axis 1, forming a ring around the central axis 1. One end of each unit segment 3 abuts against the conical surface of the central truncated cone, and the other end abuts against the conical surface of the movable truncated cone 2. Inner protrusions are provided at both ends of each unit segment 3, and these protrusions slide into grooves on the conical surfaces of the fixed truncated cone 4 and the movable truncated cone 2, respectively. This allows the ends of the unit segments 3 to slide along the grooves, thereby continuously converging or expanding.
[0037] Interconnecting hooks 31 and interconnecting grooves 34 are provided at both ends of each unit tube segment 3. The interconnecting hooks 31 can be L-shaped or T-shaped, and the shape of the interconnecting grooves 34 matches the interconnecting hooks 31 and their movement paths, thereby restricting the relative movement between unit tube segments 3 by utilizing the interaction between the interconnecting grooves 34 and the interconnecting hooks 31. The interconnecting hooks 31 extend laterally into the interconnecting grooves 34 of adjacent unit tube segments 3; the interconnecting hooks 31 can move within the interconnecting grooves 34 to change the distance between adjacent unit tube segments 3; several unit tube segments 3 are arranged in a ring around the central axis 1. The extension direction of the interconnecting hooks 31 is the same as the ring distribution direction of the unit tube segments 3.
[0038] The elastic ring can be a spring ring or an elastic rubber ring. The elastic ring connects all the unit tube segments 3 and brings the unit tube segments 3 together towards the central axis 1. Hooks 36 are provided on the inner side of both ends of the unit tube segments 3. The elastic ring is hooked onto the hooks 36, thereby providing a radial pulling force that brings the unit tube segments 3 together inward.
[0039] A clamp 5 is fitted onto the central shaft 1. After the position of the clamp 5 is fixed, the clamp 5 abuts against the end face of the movable cone 2 to restrict the movement of the movable cone 2.
[0040] like Figure 1 and Figure 2 As shown, each unit tube segment 3 can adopt an integrally formed structure; that is: the inner protrusion is located at the end of the corresponding unit tube segment 3 and is connected to the corresponding unit tube segment 3 as a whole; the interconnecting hook 31 is set as a whole with the corresponding unit tube segment 3, the interconnecting hook 31 is located at the end edge of the unit tube segment 3 and extends to the end of the adjacent unit tube segment 3; the hook 36 is also set as a whole with the unit tube segment 3; the interconnecting groove 34 is a groove structure formed on the end face of the unit tube segment 3.

The extension line of the grooves is located on the center line of the fixed cone 4. The number of grooves is equal to or less than the number of unit tube segments 3. The small end of the fixed cone 4 faces the unit tube segment 3. The fixed cone 4 is coaxially fixed on the central shaft 1. The fixed cone 4 can be fixed by key connection.
[0046] The movable cone 2 has a conical structure and is coaxially mounted on the central axis 1. It can slide along the central axis 1. Several grooves are provided on the conical surface of the movable cone 2. The extension line of the grooves is located on the center line of the movable cone 2. The number of grooves is equal to or less than the number of unit tube segments 3.

[0047] Each unit segment 3 is elongated, with several unit segments 3 arranged around the outer periphery of the central axis 1, forming a ring around the central axis 1. One end of each unit segment 3 abuts against the conical surface of the central truncated cone 4, and the other end abuts against the conical surface of the movable truncated cone 2. Some unit segments 3 have inner protrusions at both ends, which slide in engagement with grooves on the conical surfaces of the fixed truncated cone 4 and the movable truncated cone 2, respectively. Other unit segments 3 have curved inclined surfaces at both ends, which engage with the conical surfaces of the fixed truncated cone 4 and the movable truncated cone 2, respectively. This allows the ends of the unit segments 3 to slide along the grooves, thus continuously converging or expanding.
[0048] Interconnecting hooks 31 and interconnecting grooves 34 are provided at both ends of each unit tube segment 3. The interconnecting hooks 31 can be L-shaped or T-shaped, and the shape of the interconnecting grooves 34 matches the interconnecting hooks 31 and their movement paths, thereby restricting the relative movement between unit tube segments 3 by utilizing the interaction between the interconnecting grooves 34 and the interconnecting hooks 31. The interconnecting hooks 31 extend laterally into the interconnecting grooves 34 of adjacent unit tube segments 3; the interconnecting hooks 31 can move within the interconnecting grooves 34 to change the distance between adjacent unit tube segments 3; several unit tube segments 3 are arranged in a ring around the central axis 1. The extension direction of the interconnecting hooks 31 is the same as the ring distribution direction of the unit tube segments 3.

[0050] A clamp 5 is fitted onto the central shaft 1. After the position of the clamp 5 is fixed, the clamp 5 abuts against the end face of the movable cone 2 to restrict the movement of the movable cone 2.
[0051] like Figure 3-5 As shown, each unit segment 3 is a multi-component combination structure, and each unit segment 3 includes components such as the segment body 32 and the end connecting block 33.
[0052] The main body 32 of the tube segment is elongated and has threaded holes at both ends.
[0053] An end connecting block 33 is provided at the end of the segment body 32. An arc groove 35 and a screw hole are provided on the end connecting block 33. The arc groove 35 is used for the installation of the elastic ring, and the screw hole is used for the bolt to pass through so as to fix the bolt between the end connecting block 33 and the segment body 32. An end connecting block 33 is detachably connected to each end of the segment body 32.
[0054] The interconnecting hook 31 is located on the side of the end connecting block 33 and the two are integrated.
