Description

Technical Field

[0001] The present application relates to the technical field of roller equipment, and in particular to a roller device and a conveying device. Background Art

[0002] In the process of product production, conveyor belts are generally needed to transport products. When transporting products over long distances, the span of the conveyor belt is large, and there is a risk of the conveyor belt becoming loose. Therefore, the conveyor belt often needs to be tensioned. After tensioning, the load on the conveyor belt increases, which can easily cause damage to the conveyor belt's shaft bearings, leading to the risk of the conveyor belt being unable to transport products. Utility Model Content

[0003] In view of this, the present application provides a roller device, which supports the positioning column to rotate relative to the outside through a second bearing assembly, and supports the cylinder through the second bearing assembly, thereby improving the stability of the cylinder rotation through the two bearing assemblies, thereby achieving the effect of keeping the conveyor belt continuously transporting products.

[0004] The present application provides a roller device, comprising: a cylinder, an axis core, a first bearing assembly and a second bearing assembly. The cylinder is used to contact with a conveyor belt. The axis core is coaxially arranged with the cylinder and is arranged on the cylinder. At least part of the first bearing assembly is arranged in the cylinder, the first bearing assembly is located between the cylinder and the axis core, and the first bearing assembly is used to support the cylinder to rotate relative to the axis core. The second bearing assembly is connected to the axis core, and the second bearing assembly is used to contact with the outside world and support the axis core to rotate relative to the outside world.

[0005] The roller device of the above embodiment adopts the first bearing assembly to support the rotation of the cylinder relative to the shaft core, and the second bearing assembly to support the rotation of the shaft core relative to the outside world. When one of the first bearing assembly or the second bearing assembly is damaged, the remaining first bearing assembly or the second bearing assembly can continue to support the rotation of the cylinder, thereby improving the stability of the rotation of the cylinder and achieving the purpose of the cylinder supporting the conveyor belt to continuously transport products.

[0006] In some embodiments, the cylinder has two opposite ends; the first bearing assembly includes two ball bearings, one ball bearing is located at one end of the cylinder, and the other ball bearing is located at the other end of the cylinder, and each ball bearing is at least partially embedded in the cylinder.

[0007] In the above embodiment, when the two ends of a general roller are directly connected to the shaft core, the roller is easily damaged when the load on the roller is too large. Supporting the two ends of the cylinder by the first bearing assembly helps to improve the stability of the connection between the cylinder and the shaft core.

[0008] In some embodiments, the first bearing assembly further includes a support cylinder located between the two ball bearings, wherein the support cylinder is located in the cylinder body and sleeved on the shaft core.

[0009] In the above embodiment, supporting the cylinder body by the support cylinder helps to prevent the cylinder body from being damaged due to excessive force.

[0010] In some embodiments, the shaft core has two opposite ends; the second bearing assembly includes two eccentric bearings, one eccentric bearing is sleeved on one end of the shaft core, and the other eccentric bearing is sleeved on the other end of the shaft core, and each eccentric bearing is used to contact the outside world.

[0011] In the above embodiment, the eccentric bearing facilitates the adjustment of the axial direction of the cylinder relative to the driving roller, so that when the conveyor belt is installed, the position of the conveyor belt can be adjusted by adjusting the axial direction of the cylinder, and when the first bearing assembly is damaged, the risk of conveyor belt deviation can be reduced by adjusting the axial direction of the roller.

[0012] In some embodiments, the shaft core has two opposite ends. The roller device further comprises two bases, which are respectively located at two ends of the shaft core, and one base is fixedly connected to the second bearing assembly for supporting the shaft core through the second bearing assembly.

[0013] In the above embodiment, the drum device is installed and fixed by connecting the base to the outside world.

[0014] In some embodiments, in the axial direction of the cylinder, there is a gap between the base and the cylinder, and the first bearing assembly is partially located in the gap. The first bearing assembly also includes a first identification structure, which is located on the side of the first bearing assembly facing the radial direction.

[0015] In the above embodiment, during maintenance, the first identification structure in the gap is observed, thereby facilitating the determination of the rotation status of the first bearing assembly.

[0016] In some embodiments, the second bearing assembly passes through the base. The second bearing assembly further comprises a second identification structure, which is located at one end of the second bearing assembly away from the cylinder in the axial direction and extends in the radial direction of the second bearing assembly.

[0017] In the above embodiment, during maintenance, the second identification structure is observed through the base, thereby facilitating the determination of the rotation condition of the second bearing assembly.

[0018] In some embodiments, the cylinder has two opposite ends, each of which is provided with a shoulder, each shoulder extending from the surface of the cylinder to the outside of the cylinder in the radial direction of the cylinder, and a positioning space for accommodating at least a part of the conveyor belt is formed between the two shoulders in the axial direction.

[0019] In the above embodiment, the conveyor belt is restricted within the positioning space by the shaft shoulder, thereby reducing the risk of conveyor belt deviation.

[0020] In some embodiments, the height of the shoulder in the radial direction of the cylinder is less than the thickness of the conveyor belt.

[0021] In the above embodiment, the height of the shaft shoulder is smaller than the thickness of the conveyor belt, so as to reduce the risk of the shaft shoulder contacting the product on the conveyor belt.

[0022] A conveying device comprises a driver, a driving roller, a conveyor belt and the above-mentioned roller device, wherein the driver is drivingly connected to the driving roller, the driving roller is parallel to the cylinder body and is arranged at intervals, and the conveyor belt bypasses the driving roller and the cylinder body and contacts the driving roller and the cylinder body.

[0023] In the above embodiment, the roller device is used to help improve the tension of the conveyor belt and the stability of the conveyor belt carrying the product, thereby improving the stability of the conveyor belt conveying the product, and compared with setting up a tensioning mechanism, it can reduce the resistance of the tensioning roller of the tensioning mechanism.

[0050] The terms "first", "second", etc. can only distinguish different objects and cannot be understood as indicating or implying relative importance or implying the quantity, specific order or primary and secondary relationship of the indicated technical features.

[0051] It should be recognized that the dimensions of the structures shown in the drawings are given for better understanding and more convenient description, and the present application is not limited to the dimensions shown in the drawings. In order to make the present application clear, elements not related to the description are omitted from the details of this specification.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0053] The present application discloses a roller device comprising: a cylinder, an axis core, a first bearing assembly and a second bearing assembly. The cylinder is used to contact with a conveyor belt. The axis core is coaxially arranged with the cylinder and is arranged on the cylinder. At least part of the first bearing assembly is arranged in the cylinder, the first bearing assembly is located between the cylinder and the axis core, and the first bearing assembly is used to support the cylinder to rotate relative to the axis core. The second bearing assembly is connected to the axis core, and the second bearing assembly is used to contact with the outside and support the axis core to rotate relative to the outside.

[0054] The roller device of the above embodiment adopts the first bearing assembly to support the cylinder to rotate relative to the shaft core, and the second bearing assembly to support the shaft core to rotate relative to the outside world. When one of the first bearing assembly or the second bearing assembly is damaged, the remaining first bearing assembly or the second bearing assembly can continue to support the rotation of the cylinder, thereby improving the stability of the rotation of the cylinder and achieving the purpose of the cylinder supporting the conveyor belt to continuously transport products.

[0055] Some embodiments of the present application will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0056] See also Figure 1 and Figure 2 A conveying device 10 is used to convey a product (not shown), and the conveying device 10 includes a driver 11, a driving roller 12, a conveyor belt 14, and a roller device 13. The roller device 13 includes a cylinder 131. The driver 11 is drivingly connected to the driving roller 12, the driving roller 12 is parallel to the cylinder 131 and is spaced apart, and the conveyor belt 14 bypasses the driving roller 12 and the cylinder 131 and contacts the driving roller 12 and the cylinder 131.

[0057] By supporting the conveyor belt 14 for reversing by rotating the stable cylinder 131, it is helpful to improve the stability of the conveyor belt 14 in conveying products. And when it is necessary to increase the tension of the conveyor belt 14 so that the conveyor belt 14, the driving roller 12 and the cylinder 131 are interference fit, the cylinder 131 can continue to rotate under the high load of the conveyor belt 14, which helps to increase the effective power of the driving roller 12 to drive the conveyor belt 14 to rotate, thereby reducing the slippage of the conveyor belt 14 and achieving the purpose of improving the stability of the conveyor belt 14 in conveying products, thereby improving the stability of the conveyor belt 14 in conveying products. And compared with the need to set up an additional tensioning mechanism, by directly increasing the tension of the conveyor belt 14 through the interference fit of the conveyor belt 14, the driving roller 12 and the cylinder 131, the resistance generated by the tensioning roller of the tensioning mechanism on the conveyor belt 14 can be reduced, which helps to reduce the load of the conveyor belt 14, thereby reducing the load of the cylinder 131, and further helping the cylinder 131 to be able to rotate continuously and stably.

[0058] It can be understood that when the setting of the tensioning mechanism is reduced, the load of the conveyor belt 14 is additionally increased. The continuous and stable rotation of the cylinder 131 can maintain the conveyor belt 14's ability to continuously and stably feed materials, which helps to improve the quality of the products conveyed by the conveyor belt 14, or helps to increase the pre-tensioning of the conveyor belt 14 to reduce the slippage of the conveyor belt 14, thereby helping to improve the working efficiency of the conveyor belt 14.

[0059] In some embodiments, the conveying device 10 further includes a bracket (not shown) for mounting the driver 11 , the driving roller 12 , and the roller device 13 .

[0060] In some embodiments, see Figure 2 and Figure 3 The roller device 13 further includes: a base 135, a shaft core 132, a first bearing assembly 133 and a second bearing assembly 134. The base 135 is fixedly connected to the bracket, and the shaft core 132 is coaxially arranged with the cylinder 131 and passes through the cylinder 131. At least part of the first bearing assembly 133 is arranged in the cylinder 131, and the first bearing assembly 133 is located between the cylinder 131 and the shaft core 132, and the first bearing assembly 133 and the cylinder 131 are interference fit. The second bearing assembly 134 is connected to the shaft core 132, and the second bearing assembly 134 is fixedly connected to the base 135 and is used to support the shaft core 132 to rotate relative to the base 135.

[0061] After the conveyor belt 14 passes around the cylinder 131, the first bearing assembly 133 supports the cylinder 131 to rotate relative to the shaft core 132, and the second bearing assembly 134 supports the shaft core 132 to rotate. When one of the first bearing assembly 133 or the second bearing assembly 134 is damaged, the remaining, normal first bearing assembly 133 or second bearing assembly 134 can continue to support the rotation of the cylinder 131, thereby improving the stability of the rotation of the cylinder 131 and reducing the risk of the cylinder 131 stopping, so as to achieve the purpose of the cylinder 131 supporting the conveyor belt 14 to continuously convey products.

[0062] In some embodiments, the first bearing assembly 133 is located at both ends of the cylinder 131. Generally, the two ends of the roller are directly connected to the shaft core 132. When the load of the roller is too large, the roller is easily damaged. The first bearing assembly 133 of the present application supports both ends of the cylinder 131. When the load of the cylinder 131 increases, it helps to improve the stability of the connection between the cylinder 131 and the shaft core 132, thereby achieving the purpose of the cylinder 131 supporting the movement of the conveyor belt 14 with greater tension.

[0063] In some embodiments, see Figure 3 and Figure 4The first bearing assembly 133 includes two ball bearings 1331, one ball bearing 1331 is located at one end of the cylinder 131, and the other ball bearing 1331 is located at the other end of the cylinder 131. The use of ball bearings 1331 with large load-bearing capacity helps to improve the stability of the first bearing assembly 133 in supporting the rotation of the cylinder 131.

[0064] In some embodiments, the outer circumferential surface of the ball bearing 1331 is in full contact with the cylinder 131 , thereby helping to increase the contact area between the cylinder 131 and the ball bearing 1331 .

[0065] In some embodiments, the number of ball bearings 1331 is three, four, or more, which helps to increase the contact area between the first bearing assembly 133 and the cylinder 131 .

[0066] In some embodiments, the first bearing assembly 133 also includes a support tube (not shown) located between the two ball bearings 1331. The support tube is located in the cylinder 131 and is sleeved on the shaft core 132. The support tube increases the contact area between the first bearing assembly 133 and the cylinder 131, and supports the middle part of the cylinder 131 to prevent the risk of damage to the cylinder 131 due to excessive force.

[0067] In other embodiments, the first bearing assembly 133 is two roller bearings (not shown). Figure 3 and Figure 4 In the axial direction of the cylinder 131, there is a gap (not shown) between the base 135 and the cylinder 131, a part of the ball bearing 1331 extends from the cylinder 131 into the gap, and the first bearing assembly 133 further includes a first identification structure 1332 provided on the outer circumferential surface of the ball bearing 1331. When inspecting, by observing the first identification structure 1332 in the gap along the radial direction, it is convenient to judge the rotation of the ball bearing 1331. When the first identification structure 1332 is stationary relative to the bracket, it indicates that the ball bearing 1331 normally supports the cylinder 131 to rotate relative to the bracket and the ball bearing 1331. When the first identification structure 1332 moves relative to the bracket, it indicates that the ball bearing 1331 is damaged and rotates relative to the bracket driven by the cylinder 131.

[0068] In some embodiments, see Figure 3 and Figure 5The second bearing assembly 134 includes two eccentric bearings 1341, one eccentric bearing 1341 is sleeved on one end of the shaft core 132, and the other eccentric bearing 1341 is sleeved on the other end of the shaft core 132, and each eccentric bearing 1341 is interference fit with the base 135. The eccentric bearings 1341 facilitate the axial adjustment of the cylinder 131 relative to the drive roller 12, so that when the conveyor belt 14 is installed, it is convenient to adjust the axial direction of the cylinder 131 so that the cylinder 131 and the drive roller 12 are parallel to each other, so that the conveyor belt 14 can convey products in a straight line. And when the first bearing assembly 133 is damaged, the risk of deviation of the conveyor belt 14 can be reduced by adjusting the axial direction of the cylinder 131 so that the cylinder 131 and the drive roller 12 are parallel to each other. In some embodiments, please refer to Figure 3 and Figure 5 Each base 135 is provided with a through hole 1351 for accommodating the eccentric bearing 1341. The second bearing assembly 134 also includes a second identification structure 1342 provided on the side of each eccentric bearing 1341 away from the cylinder 131, and the second identification structure 1342 extends along the radial direction of the eccentric bearing 1341. When inspecting, by observing the second identification structure 1342 in the gap, it is convenient to judge the rotation of the eccentric bearing 1341. When the second identification structure 1342 is stationary relative to the bracket, it means that the eccentric bearing 1341 normally supports the shaft core 132 to rotate relative to the bracket and the base 135. When the second identification structure 1342 moves relative to the bracket, it means that the eccentric bearing 1341 is damaged and rotates relative to the bracket driven by the shaft core 132.

[0069] In some embodiments, the first identification structure 1332 and the second identification structure 1342 are alternately arranged colors or alternately arranged reflective stickers, or the first identification structure 1332 and the second identification structure 1342 are alternately arranged color coatings or alternately arranged reflective coatings.

[0070] In some embodiments, the number of eccentric bearings 1341 at each end of the shaft core 132 is two or more, which helps to increase the contact area between the second bearing assembly 134 and the base 135 .

[0071] In other embodiments, the second bearing assembly 134 is two self-aligning bearings (not shown).

[0072] In some embodiments, see Figure 6, shoulders 1311 are respectively provided at both ends of the cylinder 131, each shoulder 1311 extends from the surface of the cylinder 131 to the outside of the cylinder 131 along the radial direction of the cylinder 131, and a positioning space 1312 for accommodating at least a part of the conveyor belt 14 is formed between the two shoulders 1311 along the axial direction of the cylinder 131. The conveyor belt 14 is restricted in the positioning space 1312 by the shoulders 1311, thereby reducing the risk of the conveyor belt 14 being deviated, which helps to improve the stability of the conveyor belt 14 in conveying products in a straight line.

[0073] In some embodiments, the height of the shoulder 1311 in the radial direction is smaller than the thickness of the conveyor belt 14 , so as to reduce the risk of the shoulder 1311 protruding from the bearing surface of the conveyor belt 14 and causing the shoulder 1311 to contact the products on the conveyor belt 14 .

[0074] In some embodiments, the driver 11 is an electric motor or a hydraulic motor.

[0075] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not intended to limit the present application. As long as they are within the essential scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
