Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, and in particular to a belt roller device. Background Technology

[0002] Belt conveyors are the primary conveying equipment in tobacco processing, used to transport materials between different stages. For example, after tobacco leaves are processed by the main equipment, they fall onto the belt conveyor and are transported to the next stage by the belt's rotation. Different processing equipment is spaced apart, and some stages require long-distance transport of tobacco leaves. For belt conveyors used for long-distance transport, idlers are installed on the bottom surface of the belt to prevent collapse in the middle area. However, existing idlers have a large contact area with the belt, leading to severe wear on the belt over extended periods of operation, affecting its conveying capacity and service life.

[0003] Therefore, there is an urgent need for a belt idler device to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a belt idler device that can solve the problem that the existing idler has a large contact area with the belt, and the belt will wear out severely as the belt conveyor runs for a long time, affecting the belt's conveying capacity and service life.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A belt idler assembly is mounted on two spaced-apart supports of a belt conveyor, the belt idler assembly comprising:

[0007] The roller shaft is mounted on two supports, and the two supports are used to fix both ends of the roller shaft to the two supports respectively.

[0008] A roller and a bearing, wherein the roller and the roller shaft are connected by the bearing; the surface of the roller is provided with a plurality of grooves spaced apart;

[0009] Multiple nylon rings are provided, with each nylon ring corresponding to a groove, and each nylon ring has at least one mounting hole on its outer periphery.

[0010] A locking element that abuts against the groove after passing through the mounting hole.

[0011] As a preferred technical solution for the belt idler device, the nylon ring has three mounting holes spaced apart on its outer periphery.

[0012] As a preferred technical solution for the belt idler device, the belt idler device further includes a threaded sleeve, which is fixedly placed in the mounting hole.

[0013] As a preferred technical solution for the belt idler device, the threaded sleeve is made of steel.

[0014] As a preferred technical solution for the belt idler device, both ends of the roller shaft are provided with fixing areas, the fixing member is placed in the fixing area, the fixing member includes two nuts, the nuts are threadedly connected to the fixing area, the two nuts are respectively located on both sides of the side wall of the bracket, and both are in contact with the side wall of the bracket.

[0015] As a preferred technical solution for the belt idler device, the fixing component further includes a washer, which is placed between the nut and the side wall of the bracket.

[0016] As a preferred technical solution for the belt idler device, the bearing is provided in two parts, and the roller shaft also includes a main body area and two assembly areas. The main body area is located in the middle area of ​​the roller shaft, and the assembly area is located between the main body area and the fixed area. The diameter of the assembly area is smaller than the diameter of the main body area, and the two bearings are respectively placed in the two assembly areas.

[0017] As a preferred technical solution for the belt idler device, the roller includes a first circular hole, a second circular hole, and a third circular hole that are connected to each other.

[0018] As a preferred technical solution for the belt idler device, a positioning groove is provided on the side of the assembly area away from the main body area. The belt idler device also includes a clamp, which is placed in the positioning groove and fits against the inner ring of the bearing.

[0019] As a preferred technical solution for the belt idler device, the depth of the groove is 3mm.

[0020] The beneficial effects of this utility model are as follows:

[0021] The belt idler device provided by this utility model uses multiple nylon rings spaced apart on the roller to support the belt, reducing the contact area between the belt and the idler device. This effectively reduces belt wear after long-term operation, ensuring conveying capacity while extending belt life. Multiple grooves are provided on the outer circumference of the roller, with the nylon rings corresponding to these grooves. Locking components pass through the mounting holes of the nylon rings and abut against the grooves. When the belt runs, it drives the nylon rings to rotate, generating friction between the locking components and the groove surfaces. Therefore, the nylon rings and the roller rotate synchronously during belt operation. Since the locking components are partially placed within the grooves, they restrict the nylon rings, reducing the range of misalignment during belt rotation. In other words, the grooves correct the misalignment of the nylon rings, ensuring smooth belt rotation. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0034] like Figures 1 to 4As shown in the illustration, this embodiment provides a belt idler device, mounted on two supports spaced apart on a belt conveyor, used to support the belt in the belt conveyor and prevent the middle area of ​​the belt from collapsing. The belt idler device includes a roller shaft 1, two fixing members 2, a roller 3, bearings 4, multiple nylon rings 5, and locking components. The roller shaft 1 is mounted on the two supports, and the two fixing members 2 are used to fix both ends of the roller shaft 1 to the two supports respectively. The roller 3 and the roller shaft 1 are connected by the bearings 4, allowing the roller 3 to rotate relative to the roller shaft 1. Multiple grooves 31 are provided on the surface of the roller 3, and multiple nylon rings 5 ​​are placed corresponding to the multiple grooves 31. By fitting multiple nylon rings 5 ​​around the outer circumference of the roller shaft 1, the nylon rings 5 ​​support the belt, reducing the contact area between the belt and the belt idler device, reducing the wear of the belt after long-term operation, ensuring the belt conveying capacity while extending the belt's service life. At least one mounting hole 51 is provided on the outer periphery of the nylon ring 5. After the locking member passes through the mounting hole 51, it abuts against the groove 31. The locking member installs the nylon ring 5 into the groove 31. When the belt runs, it will drive the nylon ring 5 to rotate. At this time, the locking member passing through the nylon ring 5 and the bottom surface of the groove 31 generate friction. Therefore, when the belt runs, the nylon ring 5 and the roller 3 will rotate synchronously. Since the locking member is partially placed in the groove 31, it can restrict the nylon ring 5 and reduce the range of the nylon ring 5's deviation during the belt's rotation. That is, the setting of the groove 31 can play a corrective role for the nylon ring 5 and ensure the smoothness of the belt's rotation.

[0035] In this embodiment, a bolt is used as the locking component. The bolt has an internal thread in the mounting hole 51 and an external thread. When the operator assembles the bolt, the external and internal threads are screwed together, and the bottom of the bolt abuts against the groove 31. In this way, the bolt can be locked to the mounting hole 51, further improving the stability of the nylon ring 5 assembly.

[0036] For example, three mounting holes 51 are provided at intervals on the outer periphery of the nylon ring 5. This allows the nylon ring 5 to be more securely mounted on the outer periphery of the roller 3, while also ensuring that the nylon ring 5 is subjected to uniform force when the belt drives it to rotate. Of course, four, five, or more mounting holes 51 can also be provided at intervals on the outer periphery of the nylon ring 5, and no specific limitation is made here.

[0037] In this embodiment, the belt idler device also includes a threaded sleeve, which is placed inside the mounting hole 51. The threaded sleeve is an internally threaded fastener suitable for threaded connections. It is screwed into and tightened within the mounting hole 51, forming a standard internal thread. The threaded sleeve further enhances the connection strength between the locking element and the nylon ring 5, improves the stability of the connection, and consequently enhances the stability of the contact between the locking element and the groove 31, enabling the nylon ring 5 and the roller 3 to rotate synchronously and smoothly during belt operation. Simultaneously, the threaded sleeve also disperses the stress acting on the nylon ring 5, thereby extending its service life.

[0038] Furthermore, the threaded sleeve is made of steel, which has higher strength and better stability than plastic, allowing the locking component to be securely assembled with the nylon ring 5.

[0039] For example, both ends of the roller shaft 1 are provided with fixing areas 11, and the fixing member 2 is placed in the fixing area 11. The fixing member 2 includes two nuts 21, which are threadedly connected to the fixing areas 11. That is, both ends of the fixing areas 11 of the roller shaft 1 are threaded, and the two nuts 21 are threaded to each other with the threads on one side of the roller shaft 1. The two nuts 21 are located on both sides of the side wall of the support and are in contact with the side wall of the support. The setting of the two nuts 21 can make the roller shaft 1 more securely connected to the support, and thus more securely mounted on the two supports, avoiding the problem of the roller shaft 1 falling off when the belt is running. Furthermore, a washer 22 is provided on the side of the nut 21 that is in contact with the side wall of the support. That is, a washer 22 is provided between the nut 21 and the side wall of the support. The setting of the washer 22 can prevent the nut 21 from scratching the side wall of the support, and at the same time, the washer 22 can also reduce the risk of the nut 21 loosening, improving the safety of the belt idler device.

[0040] In this embodiment, two bearings 4 are provided. The roller shaft 1 also includes a main body area 13 and two assembly areas 12. The main body area 13 is located in the middle region of the roller shaft 1, and the assembly areas 12 are located between the main body area 13 and the fixed area 11. The diameter of the assembly area 12 is smaller than the diameter of the main body area 13. The two bearings 4 are respectively placed in the two assembly areas 12, which makes it easier for workers to assemble the bearings 4. Setting bearings 4 at both ends of the roller shaft 1 makes the assembly between the roller shaft 1 and the roller 3 more stable and the rotation of the roller 3 smoother. At the same time, the end face between the assembly area 12 and the main body area 13 can fit with the inner ring of the bearing 4, making the design of the roller shaft 1 more reasonable. Furthermore, the roller 3 includes a first circular hole, a second circular hole, and a third circular hole that are connected. The diameter of the first circular hole and the third circular hole is larger than the diameter of the second circular hole. The two bearings 4 are respectively placed in the first circular hole and the third circular hole, which makes it easier for workers to assemble the two bearings 4 and improves the rationality of the belt idler device design.

[0041] In the assembly area 12, a positioning groove 121 is provided on the side opposite to the main body area 13. The belt roller device also includes a clamp (not shown in the figure). The clamp is placed in the positioning groove 121 and is in contact with the inner ring of the bearing 4. The inner ring of the bearing 4 is in contact with the end face between the assembly area 12 and the main body area 13 on one side and with the clamp on the other side. This can prevent the inner ring of the bearing 4 from moving, realize the smooth rotation of the bearing 4, and thus improve the smoothness of the rotation of the roller 3.

[0042] Preferably, a dustproof retaining ring is embedded between the inner and outer rings of the bearing 4. The dustproof retaining ring prevents external dust from entering the rollers of the bearing 4, thereby extending the service life of the bearing 4. However, the dustproof retaining ring is a conventional industrial part and is not within the scope of protection of this utility model.

[0043] In this embodiment, the depth of the groove 31 is 3mm. If the groove 31 is too shallow, the risk of the locking component falling out of the groove 31 will increase, and the problem of the nylon ring 5 swaying after the belt has been running for a long time cannot be effectively solved. If the groove 31 is too deep, a longer bolt needs to be used to ensure that the locking component can abut against the groove 31 after passing through the mounting hole 51. Compared with conventional bolts, longer bolts are more expensive, which will increase the manufacturing cost of the belt idler device. Setting the groove 31 to a depth of 3mm not only significantly reduces the risk of the locking component falling out, but also allows the use of conventional bolts for the locking component, saving the manufacturing cost of the belt idler device.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
