Description

Technical Field

[0001] This utility model belongs to the field of float technology, specifically a new type of float. Background Technology

[0002] A float ring is a precision ring-shaped component used to assist in the slitting process of tobacco sheets (such as cigarette paper, tobacco film, tobacco sheets, etc.). Its design and function directly serve the stability, accuracy, and material protection of the slitting process. The slitting wheel needs to accurately slit the continuously fed tobacco materials (such as cigarette paper, film) into a set width during high-speed operation. The float ring is usually installed on the outer ring of the slitting wheel or at the position where it mates with the blade. Through its ring structure, it forms a slight radial pressure on the edge of the material, ensuring that the material remains flat and without deviation during slitting, and avoiding dimensional deviations in the slitting due to material relaxation.

[0003] Existing float rings have certain drawbacks in use. They consist of an inner ring, an outer ring, and connecting rubber. During use, the connecting rubber is constantly exposed to slight temperature and humidity changes and friction in the tobacco processing environment, making it prone to aging, decreased elasticity, and inability to effectively buffer the relative movement between the inner and outer rings. This can even lead to cracking, affecting the stability of the float's clamping force on the cigarette. The connecting rubber is usually bonded to the inner and outer rings through adhesion or mechanical fixation. If the bonding process is poor or subjected to prolonged tearing, it may detach, resulting in a loose float structure that cannot properly adjust the cigarette position, reducing the float's effectiveness and failing to meet user needs. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a novel float ring.

[0005] A novel float ring includes: an inner float ring and an outer float ring disposed outside the inner float ring; the inner float ring is provided with an elastic connector detachable from the outer float ring; the inner side of the outer float ring is provided with limiting protrusions connected to the elastic connectors in a circular array; wherein, the number of elastic connectors is set to 6 or 8, and the elastic connectors are respectively installed on the inner float ring and the outer float ring by a number of fastening bolts.

[0006] As a further embodiment of this utility model: the inner ring of the float ring is provided with a first connecting hole corresponding to the elastic connector; the limiting protrusion is provided with a second connecting hole aligned with the first connecting hole, and a plurality of fastening bolts are respectively matched with the first connecting hole and the second connecting hole.

[0007] As a further embodiment of this utility model: the elastic connector has an arc-shaped strip structure; the two ends of the elastic connector are respectively provided with through holes aligned with the first connecting hole and the second connecting hole, and the fastening bolt can pass through the through holes and then be installed in the first connecting hole or the second connecting hole.

[0008] As a further embodiment of this utility model: the upper and lower end faces of the elastic connector are respectively attached to one side of the inner ring and the outer ring of the float, so that the inner ring, the elastic connector and the outer ring of the float are arranged in sequence.

[0009] As a further aspect of this utility model: the inner upper and lower end faces of the outer ring of the float are provided with guide slopes that connect to the limiting protrusions. The guide slopes serve as a buffer transition. When the outer ring of the float is subjected to force, the slopes disperse the stress between the limiting protrusions and the outer ring of the float, avoiding local wear or breakage caused by right-angle connections. The outer side of the outer ring of the float is provided with a notch. The height of the limiting protrusions is smaller than the height of the middle part of the outer ring of the float. The outer ring of the float is provided with a first mounting hole arranged in a circular array. The shrunk design of the limiting protrusions reduces the contact area to reduce friction, and the guide slopes disperse stress, so that the outer ring of the float remains stable under high-speed or stress conditions.

[0010] As a further embodiment of this utility model: the contact edges of the elastic connector are rounded and polished; both ends of the elastic connector are semi-circular; the elastic connector is made of carbon fiber.

[0011] As a further embodiment of this utility model: the limiting protrusion is rounded; the limiting protrusion is set as a semi-circular arc protrusion; the end dimension of the elastic connector is smaller than the dimension of the limiting protrusion.

[0012] As a further aspect of this utility model: the rounded polishing of the contact edges of the elastic connector reduces stress concentration when engaging with the limiting protrusion, thus reducing material wear caused by long-term friction. The semi-circular structure at both ends of the elastic connector forms an arc surface that fits snugly with the semi-circular arc of the limiting protrusion. Compared to a right-angle structure, the contact area is more uniform, and pressure can be dispersed during radial limiting. This is especially suitable for high-strength, low-elongation materials like carbon fiber, preventing localized breakage. The characteristics of carbon fiber material balance rigidity and lightweight. Its strength can meet the stress requirements of high-frequency cutting operations, while its low density reduces the overall inertia of the float ring and improves stability during high-speed rotation. The semi-circular protrusion and rounded corner treatment of the limiting protrusion complement the semi-circular shape at the ends of the elastic connector. During assembly, the arc surface provides natural guidance, reducing alignment difficulty. The rounded corner design further eliminates stress concentration points, adapting to the rigid contact scenario between carbon fiber and the metal outer ring.

[0013] As a further embodiment of this utility model: the inner ring of the float is configured as a circular ring structure; the width of the inner ring of the float is greater than the end dimension of the elastic connector; the outer wall of the inner ring of the float is provided with a second mounting hole in a circular array.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) This utility model connects the inner and outer rings of the float ring with an elastic connector made of carbon fiber, avoiding the problems of decreased elasticity due to aging of the connecting rubber and the problem of weak connection of the connecting rubber. The inner and outer rings of the float ring and the elastic connector work together to evenly distribute the tension of the material, the centrifugal force of high-speed rotation and the contact pressure with the blade during the cutting process to the entire annular structure, avoiding deformation or breakage caused by local stress concentration. It works with the limiting protrusion and the guide slope to ensure the symmetry of the force on the float ring, reduce the eccentric vibration when the float ring rotates at high speed, and reduce the stress concentration when the elastic connector and the limiting protrusion work together. In addition, the elastic connector can be disassembled and replaced after a problem occurs, without replacing the entire float ring, which extends the service life of the float ring and reduces people's economic losses and improves the use effect of the float ring.

Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please see Figure 1 - Figure 5 This application provides a novel float ring, comprising: an inner float ring 1 and an outer float ring 2 disposed outside the inner float ring 1; the inner float ring 1 is provided with an elastic connector 3 detachable from the outer float ring 2; the inner side of the outer float ring 2 is provided with limiting protrusions 4 arranged in a circular array and connected to the elastic connectors 3; wherein, the number of elastic connectors 3 is set to 6 or 8, and the elastic connectors 3 are respectively installed on the inner float ring 1 and the outer float ring 2 by a number of fastening bolts.

[0025] In this embodiment, the original float ring is composed of an inner float ring 1, an outer float ring 2 and a connecting rubber 12. The elastic connector 3 is aligned with the inner float ring 1 and the outer float ring 2 respectively. The fastening bolts install one end of the elastic connector 3 on the inner float ring 1 and the fastening bolts install the other end of the elastic connector 3 on the limiting protrusion 4.

[0026] In this utility model, the inner ring 1 of the float ring is provided with a first connecting hole 5 corresponding to the elastic connector 3; the limiting protrusion 4 is provided with a second connecting hole 6 aligned with the first connecting hole 5, and a number of fastening bolts are respectively matched with the first connecting hole 5 and the second connecting hole 6.

[0027] In this embodiment, the fastening bolt installs one end of the elastic connector 3 into the first connecting hole 5 on the inner ring 1 of the float, and installs the other end of the elastic connector 3 into the limiting protrusion 4 through the fastening bolt, so that the fastening bolt is connected to the second connecting hole 6.

[0028] In this utility model, the elastic connector 3 has an arc-shaped strip structure; the two ends of the elastic connector 3 are respectively provided with through holes 7 aligned with the first connecting hole 5 and the second connecting hole 6, and the fastening bolt can pass through the through holes 7 and then be installed in the first connecting hole 5 or the second connecting hole 6.

[0029] In this utility model, the upper and lower end faces of the elastic connector 3 are respectively attached to one side of the inner ring 1 and the outer ring 2 of the float ring, so that the inner ring 1, the elastic connector 3 and the outer ring 2 of the float ring are arranged in sequence.

[0030] In this embodiment, the outer ring 2 of the float ring is placed on the lower side, the elastic connector 3 is placed above the outer ring 2 of the float ring and aligned with the limiting protrusion 4, one end of the elastic connector 3 is fixed with the limiting protrusion 4, the inner ring 1 of the float ring is placed above the elastic connector 3, the elastic connector 3 is aligned with the first connecting hole 5 on the inner ring 1 of the float ring, and the elastic connector 3 is fixed with the inner ring 1 of the float ring.

[0031] In this invention, the inner upper and lower end faces of the outer ring 2 of the float ring are provided with guide slopes 8 that connect to the limiting protrusions 4. The guide slopes 8 serve as a buffer transition. When the outer ring 2 of the float ring is subjected to force, the slopes disperse the stress between the limiting protrusions 4 and the outer ring 2 of the float ring, avoiding local wear or breakage caused by right-angle connection. The outer side of the outer ring 2 of the float ring is provided with a notch 9. The height of the limiting protrusions 4 is smaller than the height of the middle part of the outer ring 2 of the float ring. The outer ring 2 of the float ring is provided with first mounting holes 10 in a circular array. The short design of the limiting protrusions 4 reduces the contact area to reduce friction, and the guide slopes 8 disperse stress, so that the outer ring 2 of the float ring remains stable under high speed or stress conditions.

[0035] In this invention, the rounded polishing of the contact edge of the elastic connector 3 reduces stress concentration when it mates with the limiting protrusion 4, thus reducing material wear caused by long-term friction. The semi-circular structure at both ends of the elastic connector 3 forms an arc surface that fits snugly with the semi-circular arc of the limiting protrusion 4. Compared with a right-angle structure, the contact area is more uniform, which can disperse pressure during radial limiting. This is especially suitable for high-strength, low-elongation materials such as carbon fiber, avoiding local breakage. The characteristics of carbon fiber material are: it combines rigidity and lightweight. Its strength can meet the stress requirements of high-frequency cutting operations, while its low density can reduce the overall inertia of the float ring and improve stability during high-speed rotation. The semi-circular protrusion and rounded corner treatment of the limiting protrusion 4 complement each other with the semi-circular shape at the end of the elastic connector 3. During assembly, the arc surface provides natural guidance, reducing the difficulty of alignment. The rounded corner design further eliminates stress concentration points, adapting to the rigid contact scenario between carbon fiber and the metal outer ring.
