Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass bending and tempering equipment, in particular to an elastic conveying roller. Background Art
[0002] The conveyor rollers of existing flexible-shaft bending and tempering equipment consist of a steel wire mandrel and a conveyor wheel attached to it. The steel wire mandrel is woven from multiple strands of fine steel wire and can be bent into any desired curve. The conveyor wheel and the steel wire mandrel are bonded together with a strong adhesive. However, because the steel wire mandrel is flexible but lacks elasticity and rigidity, it struggles to form a precise arc after bending. This results in an inaccurate curvature radius and large wave patterns in the resulting tempered glass. Furthermore, synchronous power transmission is also impossible. Furthermore, once the conveyor wheel and the steel wire mandrel are bonded together, they are difficult to separate, making replacement and maintenance difficult. Utility Model Content
[0003] To address the aforementioned technical issues, the present invention provides an elastic conveyor roller. By utilizing a high-quality spring steel core shaft and connecting a conveyor wheel to the core shaft through tensioning, the conveyor wheel can bend to the desired curve along with the core shaft and simultaneously rotate with the core shaft to convey curved glass. The core shaft exhibits excellent elasticity and rigidity, allowing precise bending to the desired radius of curvature and free extension to its original position upon removal of external forces. Furthermore, the conveyor wheel is easily installed and removed.
[0004] In order to achieve the above technical purpose, the technical solution adopted is: an elastic conveyor roller, including a spring steel core shaft and a plurality of conveying wheels fixed on the spring steel core shaft, the conveying wheel consists of a main wheel body, a pressure cover, a bolt and a tensioning ring, the main wheel body is sleeved on the spring steel core shaft, a two-stage stepped hole is opened at the center of the main wheel body, the first-stage stepped end face of the two-stage stepped hole is opened with threaded holes evenly distributed along the circumference, a tensioning ring with a clearance fit sleeved on the spring steel core shaft is installed in the space between the second-stage step of the two-stage stepped hole and the spring steel core shaft, the inner surface of the tensioning ring is a cylindrical surface, and the outer surface is a torus or a conical surface, The pressure cover is sleeved on the spring steel core shaft. The pressure cover consists of an end cover that matches the first step and a boss protruding from one side of the end cover. The outer wall of the boss matches the side of the second step. The end of the inner wall of the boss is a conical surface that shrinks from the outside to the inside. The end cover is provided with a bolt hole that matches the threaded hole. The pressure cover is installed in the two-step hole. The boss extends between the tensioning ring and the side of the second step. As the bolt is inserted into the bolt hole and the threaded hole, the pressure cover is locked. The conical surface of the boss presses the tensioning ring, causing the tensioning ring to shrink and connect with the spring steel core shaft, so that the conveying wheel is driven to rotate when the spring steel core shaft rotates.
[0005] Furthermore, the tensioning ring is an open-loop structure.
[0006] Furthermore, the diameter of the spring steel core shaft is preferably between 4 and 8 mm.
[0007] The beneficial effects of the utility model are:
[0008] This utility model features an elastic conveyor roller that can be used in applications requiring curved roller conveyance, primarily in the field of glass bending and tempering equipment. The elastic mandrel employed in this utility model exhibits excellent torsional rigidity and arc-forming accuracy, contributing to improved product quality in bent and tempered glass, resulting in smoother, more precise curvatures and superior surface optical quality. The tensioning connection between the conveyor roller and the elastic mandrel is reliable and resists loosening, making the conveyor roller easily removable and removable, allowing for easy replacement and adjustment.
[0009] The tensioning ring is designed as an open-loop structure, which is convenient for production and installation, and can also better cooperate and connect with the elastic core shaft when shrinking. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following provides preferred embodiments of the utility model in conjunction with the accompanying drawings to illustrate the technical solution of the utility model in detail. Here, the corresponding drawings will be provided to illustrate the utility model in detail. It should be noted that the preferred embodiments described herein are only for the purpose of illustrating and explaining the utility model and are not intended to limit or restrict the utility model.
[0017] like Figure 1As shown, an elastic conveying roller includes a spring steel core shaft 1 and a plurality of conveying wheels 2 fixed on the spring steel core shaft 1. When the spring steel core shaft 1 is bent into a target curve, the conveying wheels 2 are displaced along with the core shaft. The spring steel core shaft 1 has good elasticity and rigidity. After bending the glass, it rebounds and drives the conveying wheels to convey the curved glass by rotating.
[0018] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, the conveying wheel 2 consists of a main wheel body 3, a pressure cover 4, a bolt 5 and a tension ring 6. The main wheel body 3 is used to support the glass for transmission and bending deformation. It is sleeved on the spring steel core shaft 1 with a clearance fit. The main body 3 is a circular ring structure. The center of the main wheel body 3 is provided with two-level stepped holes 301. The stepped hole on the outer side forms the first step 301-1, and the stepped hole on the inner side forms the second step 301-2. The end face of the first step 301-1 is provided with threaded holes 302 evenly distributed along the circumference. The second step 301-2 is provided with threaded holes 302 evenly distributed along the circumference. The space between the spring steel core shafts 1 is provided with a tensioning ring 6 which is loosely fitted on the spring steel core shaft 1. The inner surface of the tensioning ring 6 is a cylindrical surface, and the outer surface is a torus or a conical surface. The tensioning ring 6 is made of a material that can be compressed and deformed, such as rubber, steel wire, spring steel, etc., or the tensioning ring 6 has a structure with a shrinkage deformation amount, such as a notch, an opening, etc. The pressure cover 4 is loosely fitted on the spring steel core shaft 1. The pressure cover 4 is composed of an end cover 401 that matches the first step 301-1 and an end cover 401 that is provided on one side of the end cover 401. The outer wall of the end cover 401 is in contact with the side of the first step 301-1. The boss 402 can be set as an annular boss or a block-shaped boss arranged in an annular manner. The outer wall surface of the boss 402 matches the side surface of the second step 301-2. The end of the inner wall surface of the boss 402 is a conical surface that shrinks from the outside to the inside. The external direction refers to the direction of the main wheel body 3, and the internal direction refers to the direction of the end cover 401. The end cover 401 is provided with a bolt hole 401-1 that matches the threaded hole 302. The pressure cover 4 is installed Installed in the two-step hole 301, the boss 402 extends between the tensioning ring 6 and the side of the second step 301-2. As the bolt 5 is inserted into the bolt hole 401-1 and the threaded hole 302 to lock the gland 4, the conical surface of the boss 402 presses the tensioning ring 6, causing the tensioning ring 6 to shrink and connect with the spring steel core shaft 1, so that the conveying wheel 2 is driven to rotate when the spring steel core shaft 1 rotates. Conversely, if the conveying wheel 2 needs to be replaced, the bolt 5 is loosened, the tensioning ring 6 rebounds, and the spring steel core shaft 1 and the tensioning ring 6 are separated, and the conveying wheel can be replaced.
[0019] If the spring steel mandrel 1 is made of spring steel and undergoes a heat treatment process, it is cylindrical with a diameter within the range of 4-8 mm. The spring steel mandrel 1 within this range is elastic enough to return to its original position without breaking. This material of spring steel mandrel 1 is more resistant to high temperatures and wear, and has a longer service life.
[0020] The tensioning ring 6 is an open-loop structure and can be made of spring steel. The inner surface is a cylindrical surface or a conical surface. The diameter of the conical surface gradually decreases from the main wheel body to the pressure cover. The tensioning ring and the spring steel core shaft 1 are clearance-fitted, and the tolerance value of the clearance is +0.05 to +0.2 mm. The width of the cylindrical surface is 1 to 3 mm. This design allows for quick installation of the tensioning ring 6, is wear-resistant, easy to install, and has shrinkage.
[0021] The above are merely preferred embodiments of the present invention and are not intended to limit or restrict the present invention. Researchers or technicians in this field will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection claimed by the present invention.
