Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slitting equipment, and specifically relates to a new type of roller. Background Art
[0002] The roller is one of the important components in the slitting equipment and plays roles such as feeding, drafting, and output in textile machinery, and is widely used in mechanisms such as drafting, carding, and conveying. It usually consists of a metal shaft and two side-supported drums, and can control the winding or placement of materials through manual or automatic operations. The roller plays a role in supporting and guiding materials in the slitting equipment, enabling them to pass through the cutting mechanism smoothly for cutting. This design can ensure the stability of materials during the cutting process, thereby obtaining accurate cutting results.
[0003] The wire electrode cutting machine realizes cutting through the high-speed movement of the wire electrode driven by the wire roller. For large stone cutting machines, because the cutting workpieces are large, the rollers are not only large but also long. The traditional rollers have the following problems: 1. Reinforcing ribs are welded inside the roller, and the two end covers are also pressed in and then welded. In the case of a long and large roller structure, welding the internal reinforcing ribs and the two end covers will cause the overall deformation of the roller. The deformed roller is difficult to adjust the dynamic balance, and it is impossible to ensure the stability and accuracy of materials during the slitting process. 2. The rubber coating and grooving of the roller also require rubber coating and grooving equipment of matching length. If there is no equipment of matching length, it will be difficult to rubber coat and groove the roller with a long axial dimension, which brings inconvenience. 3. For rollers with a long axial dimension, the cutting wire ropes on the roller are in a row and contact its outer surface. When working, the surface of the roller is subjected to the tension of a long row of wire ropes and there is a risk of bending, which will affect the overall rigidity of the roller, resulting in uneven forces and cutting depths when the wire ropes guiding and supporting the roller cut the workpieces, seriously affecting the cutting quality and accuracy of the workpieces.
[0004] Therefore, a roller that can solve the above problems is needed. Summary of the Utility Model
[0005] Aiming at the defects of the prior art, the utility model proposes a new type of roller. The reinforcing ribs and the end covers at both ends are connected to the roller core through fasteners, avoiding the overall deformation of the roller caused by welding connection, ensuring the stability and accuracy of materials during the slitting process. The colloid structure of the roller adopts a segmented type, which is convenient for rubber coating and grooving, and is easy to install. Each section of the colloid structure adopts an inner metal sleeve and an outer colloid layer. The metal sleeve adopts a variable diameter design, and a ferrule is installed between adjacent metal sleeves, so that only the ferrule contacts the roller core after assembly, reducing the weight of the roller, reducing the deformation of the roller core, and improving the overall structural stiffness.
[0006] The present utility model provides a novel roller, which includes a roller core body, a colloidal structure coated on the outer circle of the roller core body, a plurality of reinforcing ribs arranged at intervals in the roller core body, and end caps buckled at both ends of the roller core body; the reinforcing ribs and the end caps are installed on the roller core body through fasteners.
[0007] Further, the colloidal structure is divided into an integral structure and a segmented structure; each section of the segmented structure of the colloidal structure is sequentially sleeved on the roller core body; the inner side of each section of the colloidal structure is divided into a straight cylinder structure and a cone structure.
[0008] Further, the colloidal structures of the straight cylinder structure and the cone structure both include a metal sleeve sleeved on the roller core body and a colloid coated on the outer surface of the metal sleeve; the metal sleeve of the straight cylinder structure is in contact with the outer surface of the roller core body, and the metal sleeve of the cone structure is arranged on the periphery of the roller core body.
[0009] Further, the colloidal structure of the straight cylinder structure further includes a first connecting key installed on the inner surface of the metal sleeve; a key groove for installing the first connecting key is provided on the outer surface of the roller core body, and the metal sleeve and the roller core body are connected through the first connecting key.
[0010] Further, the central hole of the metal sleeve of the colloidal structure of the cone structure is designed with a variable diameter, and its aperture is larger than the outer diameter of the roller core body.
[0011] Further, second trapezoidal holes are provided on the inner sides of both ends of the central hole of the metal sleeve, and the second trapezoidal holes of adjacent colloidal structures are connected to form an annular groove with a taper angle at both ends.
[0012] Further, it further includes a plurality of ferrules; both ends of the cross section of the ferrule have a taper angle, and each ferrule is sleeved on the roller core body at intervals and is located in the corresponding annular groove, and the ferrules are respectively connected to the side walls of the metal sleeve and the roller core body.
[0013] Further, a plurality of grooves for installing steel wires are provided on the surface of the colloid, and the segmented structure of the colloidal structure is divided according to the length of the grooved part on the surface of the colloid, or divided in an equal division form.
[0014] Further, the ferrule has a central hole matching the outer diameter of the roller core body, and only the inner wall of the ferrule is in contact with the outer surface of the roller core body.
[0015] Further, the ferrule and the roller core body are connected by a key, and the ferrule and the metal sleeve are connected by screws.
[0016] The beneficial effects of the present utility model are:
[0017] First, compared with the traditional method of fixing the reinforcing rib and the end cap to the roller core by welding, the reinforcing rib and the end cap of the present utility model are connected to the roller core by threads, solving the problem of deformation of the overall structure of the roller caused by welding. This structure can adjust the dynamic balance of the roller by adjusting the weight of the reinforcing ribs at different positions inside the roller core or replacing the weight of the end caps at both ends of the roller core, avoiding the phenomenon of dynamic imbalance during the rotation of the roller, enabling the roller to rotate smoothly, and thus ensuring the stability and accuracy of the material during the slitting process;
[0018] Second, in the preferred implementation, compared with the traditional integral colloid structure, the segmented colloid structure of the present utility model solves the problem of difficult grooving of the colloid structure due to the excessive length of the roller. At the same time, during the use of the roller, it can be replaced according to the wear condition of each section, saving the manufacturing cost of workpiece cutting and facilitating disassembly and assembly;
[0019] Third, in the preferred implementation, when the metal sleeve of the present utility model adopts a straight cylinder structure, adjacent colloid structures are connected by pins, and each section of the colloid structure is connected to the roller core by keys, preventing the sleeved colloid structure from rotating axially along the roller core;
[0020] Fourth, in the preferred implementation, when the metal sleeve of the present utility model adopts a conical structure, the ferrule is installed on the roller core and locked with the metal sleeve as a whole by fasteners. The central hole diameter of the metal sleeve is larger than the outer diameter of the roller core, so that the metal sleeve is non-contact connected to the roller core, and the whole roller forms a double-layer structure of tube-in-tube, reducing the weight of the roller. When the roller bears the bending moment of the wire rope, the force is transmitted from the inclined surfaces on both sides of the second trapezoidal hole to the ferrule, and the ferrule bears the tensile force of the wire rope. By installing reinforcing ribs at this contact part, the anti-bending moment ability of the roller core is further improved, reducing the deformation of the roller core and improving the rigidity of the whole roller.

[0036] Embodiment 1
[0037] Refer to the attached instructions Figures 1-3 The present utility model describes a new type of roller, including a roller core 1, a colloid structure 2 wrapped around the outer ring of the roller core 1, a plurality of reinforcing ribs 3 spaced in the roller core 1, and end caps 5 buckled at both ends of the roller core 1. The reinforcing ribs 3 and the end caps 5 are installed on the roller core 1 through a first fastener 4.
[0038] Specifically, a plurality of threaded holes are provided on the wall surface and the thick wall parts at both ends of the roller core 1. The reinforcing rib 3 is a disc matching the inner diameter of the roller core 1. A plurality of threaded holes corresponding to the wall surface of the roller core 1 are provided around the reinforcing rib 3. The corresponding first fastener 4 penetrates through the threaded holes of the reinforcing rib 3 and the wall surface of the roller core 1 to install the reinforcing rib 3 in the roller core 1. Through holes corresponding to the threaded holes at both ends of the roller core 1 are provided on the end cap 5. The corresponding first fastener 4 penetrates through the through holes of the end cap 5 and the threaded holes at both ends of the roller core 1 to install the end cap 5 at both ends of the roller core 1.
[0039] During installation, the reinforcing rib 3 and the end cap 5 are sequentially installed on the roller core 1, and then the colloid structure 2 is wrapped around the periphery of the roller core 1.
[0040] The reinforcing rib 3 and the end cap 5 are provided with a mutually penetrating central hole for installation on the rotating shaft of a multi-wire cutting machine.
[0041] Adopting the structure of this embodiment, compared with the traditional method of fixing the reinforcing rib and the end cap to the roller core by welding, the reinforcing rib and the end cap of the present utility model are threadedly connected to the roller core, solving the problem of deformation of the overall structure of the roller caused by welding. This structure can adjust the dynamic balance of the roller by adjusting the weight of the reinforcing ribs at different positions inside the roller core or replacing the weight of the end caps at both ends of the roller core, avoiding the phenomenon of dynamic imbalance during the rotation of the roller, enabling the roller to rotate smoothly, and thus ensuring the stability and accuracy of the material during the slitting process.
[0042] Embodiment 2
[0043] Refer to the attached instructions Figures 4-7 This embodiment includes all the structures of Embodiment 1, and the colloid structure 2 adopts a segmented structure. The inner side of each segment of the colloid structure 2 is a straight cylinder structure. The segmented colloid structures 2 are sequentially sleeved on the roller core 1. The end caps 5 are installed at both ends of the roller core 1 and the colloid structure 2. The two ends of the sleeved colloid structures 2 are pressed by the end caps 5, so that the adjacent colloid structures 2 are closely fitted.
[0044] Preferably, one end of each segment of the colloid structure 2 is provided with a pin, and the other end is provided with a pin hole. Each segment of the colloid structure 2 extends from the end with the pin into the end with the pin hole of the adjacent colloid structure 2 and is sequentially sleeved. The pins and the pin holes are arranged along the axial direction of the colloid structure 2.
[0045] In one implementation, each section of the colloid structure 2 is integrally formed of hard plastic.
[0046] In another implementation, each section of the colloid structure 2 adopts a multi-layer combined structure, including a metal sleeve 20 sleeved on the outer surface of the roller core 1, a colloid 21 coated on the outer surface of the metal sleeve 20, and a first connecting key 22 installed on the inner surface of the metal sleeve 20.
[0047] The first connecting key 22 is installed on the inner surface of the metal sleeve 20 through a fastener. The first connecting key 22 is a strip structure and its length matches the axial dimension of each section of the colloid structure 2. A keyway for installing the first connecting key 22 is provided on the roller core 1, and the keyway on the roller core 1 axially penetrates the outer surface of the roller core 1, so that all the first connecting keys 22 of the sleeved colloid structures 2 are embedded in the keyway of the roller core 1 to prevent the colloid structure 2 from rotating.
[0048] A channel for the steel wire rope is provided on the surface of the colloid 21. There are various ways to segment the colloid structure 2. In one implementation, the colloid structure 2 is equally divided, which is applicable to the case where the colloid structure 2 is fully grooved. In another implementation, the colloid structure 2 is segmented according to the length of the grooved part on the surface of the colloid structure 2, and the colloid structure 2 is segmented into a grooved part and an ungrooved part. Both of these methods can open the parts that need to be grooved in advance and then assemble them, which is convenient for segmented installation of the roller.
[0049] Adopting the structure of this embodiment, compared with the traditional integral colloid structure, the segmented colloid structure of the present utility model solves the problem of difficult grooving of the colloid structure due to the excessive length of the roller. At the same time, during the use of the roller, it can be replaced according to the wear condition of each section, saving the cutting and manufacturing cost of the workpiece and being convenient for disassembly and assembly; adjacent colloid structures are connected by pins, and each section of the colloid structure and the roller core are connected by keys to prevent the sleeved colloid structure from rotating axially along the roller core.
[0050] Embodiment 3
[0051] Referring to the attached drawings of the specification Figures 8-11 , the same as Embodiment 2, this embodiment includes all the structures of Embodiment 1 ( Figure 8 the reinforcing rib 3 is not shown), and the colloid structure 2 adopts a segmented structure, the inner side of each section of the colloid structure 2 is a conical structure, and each section of the colloid structure 2 adopts a multi-layer combined structure.
[0052] The difference from Embodiment 2 is that in Embodiment 2, the metal sleeve 20 is sleeved on the outer surface of the roller core 1, and the metal sleeve 20 and the roller core 1 are key-connected. In this embodiment, the metal sleeve 20 is sleeved around the roller core 1 and does not contact the outer surface of the roller core 1, and the metal sleeve 20 and the roller core 1 are not key-connected.
[0053] Specifically, the central hole of the metal sleeve 20 has a variable diameter structure. A first circular hole 200 is provided in the middle section of the central hole of the metal sleeve 20. First trapezoidal holes 201 are provided at both ends of the first circular hole 200. The outer side of each first trapezoidal hole 201 is connected to a second circular hole 202, and the outer side of each second circular hole 202 is connected to a second trapezoidal hole 203. The short sides of the first trapezoidal holes 201 and the short sides of the second trapezoidal holes 203 are respectively located on both sides of the second circular hole 202. The two first trapezoidal holes 201, the two second circular holes 202, and the two second trapezoidal holes 203 are symmetrically arranged with respect to the central axis of the first circular hole 200 and the center line perpendicular to the central axis. The second trapezoidal holes 203 of adjacent colloid structures 2 are connected to form an annular groove with an outer cone angle. The central hole diameter of the metal sleeve 20 is larger than the outer diameter of the roller core 1. Further, the hole diameters of the first circular hole 200, the first trapezoidal hole 201, and the second circular hole 202 are all larger than the outer diameter of the roller core 1.
[0054] The roller of this embodiment further includes a plurality of ferrules 6. Both ends of the cross-section of the ferrule 6 have a taper angle, which is used to match the annular groove formed by the second trapezoidal holes 203 of adjacent colloid structures 2. Each ferrule 6 is sleeved on the roller core 1 at intervals and is located in the corresponding annular groove. The ferrules 6 are respectively connected to the side walls of the metal sleeve 20 and the roller core 1.
[0055] Further, a plurality of protruding annular grooves 10 are provided on the outer surface of the roller core 1. The lower half of the second connecting key 8 is embedded in the annular groove 10 and fixed by a fastener. A key groove matching the installation of the second connecting key 8 is provided on the inner surface of the ferrule 6. The ferrule 6 and the roller core 1 are connected by a key connection.
[0056] A plurality of threaded holes are opened on the inner sides of both ends of the metal sleeve 20. Further, the plurality of threaded holes are opened axially inward from the short sides of the second trapezoidal holes 203 and are arranged in an annular array around the second circular hole 202. The ferrule 6 has a central hole matching the outer diameter of the roller core 1. A through hole matching the threaded hole of the metal sleeve 20 is provided inside the taper angle of the ferrule 6. A corresponding second fastener 7 passes through the through hole of the ferrule 6 and the threaded hole of the metal sleeve 20 to connect the ferrule 6 and the metal sleeve 20 into one body.
[0057] With the structure of this embodiment, the colloid structure 2 of the roller adopts a segmented structure. The ferrule 6 is installed on the roller core 1 and locked with the metal sleeve 20 as a whole through fasteners. The central aperture of the metal sleeve 20 is larger than the outer diameter of the roller core 1, so that the metal sleeve 20 is connected to the roller core 1 in a non-contact manner. The whole roller forms a double-layer structure of a tube within a tube. When the roller bears the bending moment of the steel wire rope, the force is transmitted from the inclined surfaces on both sides of the second trapezoidal hole 203 to the ferrule 6, and the ferrule 6 bears the tension of the steel wire rope. In a preferred implementation, by installing a reinforcing rib 3 at this contact part, the bending moment resistance of the roller core 1 is further improved, and the rigidity of the whole roller is improved.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
