Description

Technical Field

[0001] This utility model belongs to the technical field, specifically relating to a mid-section interconnected coiling device for 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 mid-section interconnected coil device for tube segments.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A mid-section interconnection type coil assembly for tube segments includes:

[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 segment abuts at one end with the conical surface of the intermediate frustum and at the other end with the conical surface of the movable frustum; L-shaped interconnecting hooks and L-shaped interconnecting grooves are respectively provided on two opposite sides in the middle of the unit segment; the interconnecting hooks extend beyond the unit segment they are located and into the interconnecting grooves of adjacent unit segments; the interconnecting hooks can move in the interconnecting grooves to change the distance between adjacent unit segments; several unit 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: a clearance groove is provided on the outer wall of the unit segment, and the clearance groove is connected to the interconnection groove; the interconnection hook can be assembled into the interconnection groove from the clearance groove.

[0014] As an alternative or supplement to the above structure: a stop block is embedded in the clearance groove, the outer surface of the stop block is flush with the outer wall of the unit tube segment; the side of the stop block abuts against the interconnecting hook to prevent the interconnecting hook from falling out of the interconnecting groove.

[0015] As an alternative or supplement to the above structure: there are multiple interconnecting hooks, and the hook heads of each interconnecting hook face the same direction, and the direction of the hook heads is parallel to the length direction of the unit tube segment; the interconnecting slots of two adjacent unit tube segments correspond one-to-one with the interconnecting hooks.

[0016] As an alternative or supplement to the above structure: an interconnecting hook and an interconnecting groove are provided at one-third of the length of the unit tube segment; an interconnecting hook and an interconnecting groove are also provided at two-thirds of the length of the unit tube segment.

[0017] As an alternative or supplement to the above structure: an inner protrusion is provided at both ends of each unit segment, and a groove that slides with the inner protrusion is provided on the conical surface of the movable cone and the fixed cone.

[0018] As an alternative or supplement to the above structure: hooks are provided on the inner sidewalls at both ends of the unit segment, and the hooks are connected to the elastic rings.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. In this scheme, since the interconnecting groove and interconnecting hook are set in the middle of the unit tube segment, a through groove will not be formed on the unit tube segment. Even after the number of unit tube segments increases and the width becomes narrower, the structural strength of the unit tube segment can still be guaranteed. Thus, the structural design can be used to improve the deformation resistance of the unit tube segment, thereby making up for the problem of weakened mechanical properties such as deformation resistance caused by the material used in the unit tube segment.

[0021] 2. At the same time, the mutual cooperation of the interconnecting groove and the interconnecting hook achieves the limiting function. The relative position of the two facilitates the positioning when the interconnecting groove and the interconnecting hook are connected. The operation path of different interconnecting hooks of different unit segments is short during installation. Attached Figure Description

[0026] 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.

[0027] Example 1

[0028] like Figures 1 to 2 As shown, this embodiment designs a coil winding device with interconnected sections in the middle of the tube segments, including components such as a central shaft 1, a movable cone 2, a unit tube segment 3, a fixed cone 4, and an elastic ring 5.

[0029] The central shaft 1 adopts a circular long rod structure, and a keyway 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.

[0030] 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.

[0031] 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 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.

[0032] Each unit segment 3 is elongated. Several unit segments 3 are arranged around the outer periphery of the central axis 1, forming a tubular structure with the central axis 1 as the center. 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. Inner protrusions 34 are provided at both ends of each unit segment 3, and these protrusions 34 slide in engagement with 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.

[0033] In the middle of the unit segment 3, L-shaped interconnecting hooks 33 and L-shaped interconnecting grooves 32 are respectively provided on two opposite sides in the width direction. The interconnecting groove 32 includes a first groove and a second groove that are perpendicular to each other, forming an L-shape. The width of the first groove is approximately equal to the width of the hook shank of the interconnecting hook 33, and the width of the second groove is approximately equal to the width of the hook head of the interconnecting hook 33. The first and second grooves have the same height. The width direction of the first and second grooves is consistent with the length direction of the unit segment 3. The height direction of the first and second grooves is consistent with the thickness direction (or inward / outward direction) of the unit segment 3. The length of the hook head is greater than the length of the second groove, allowing the interconnecting hook 33 to move within the second groove; the length direction of the interconnecting hook 33 is consistent with the width direction of the unit segment 3.

[0034] Multiple interconnecting hooks 33 can be arranged along the length of the unit tube segment 3, and the hook heads of each interconnecting hook 33 face the same direction. Furthermore, the direction of the hook heads is parallel to the length of the unit tube segment 3. The interconnecting slots 32 of two adjacent unit tube segments 3 correspond one-to-one with the interconnecting hooks 33.

[0035] Interconnecting hook 33 extends beyond the unit segment 3 it is located in and extends into the interconnecting groove 32 of the adjacent unit segment 3; the interconnecting hook 33 can move in the interconnecting groove 32 to change the distance between adjacent unit segments 3; several unit segments 3 are arranged in a ring around the central axis 1.

[0036] The elastic ring 5 can be a spring ring or an elastic rubber ring. The elastic ring 5 connects all the unit tube segments 3 and brings the unit tube segments 3 together towards the central axis 1. Hooks 35 are provided on the inner side at both ends of the unit tube segments 3. The elastic ring 5 is hooked onto the hooks 35, thereby providing a radial pulling force that brings the unit tube segments 3 together inward.

[0037] Furthermore, a clearance groove is formed on the outer wall of the unit segment 3, and the clearance groove communicates with the interconnecting groove 32; the interconnecting hook 33 can be assembled into the interconnecting groove 32 from the clearance groove. A stop block 31 is embedded in the clearance groove, and the outer surface of the stop block 31 is flush with the outer wall of the unit segment 3; the side of the stop block 31 abuts against the interconnecting hook 33 to prevent the interconnecting hook 33 from falling out of the interconnecting groove 32.

[0038] When there are only two interconnecting hooks 33 on the unit tube segment 3, one of them is located at one-third of the length direction of the unit tube segment 3, and the other is located at two-thirds of the length direction of the unit tube segment 3; at the same time, an interconnecting groove 32 is provided on the opposite side of the two interconnecting hooks 33.

[0039] An inner protrusion 34 is provided at both ends of each unit segment 3, and a groove that slides with the inner protrusion 34 is provided on the conical surface of the movable cone 2 and the fixed cone 4.

[0040] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
