Description

Technical Field

[0001] This utility model relates to the technical field of conveyors, and in particular to a belt conveyor roller. Background Technology

[0002] As a key material conveying equipment in many fields such as industrial production and logistics transportation, the performance of the roller, the core component of the belt conveyor, plays a decisive role in the overall conveying efficiency and stability.

[0003] However, traditional designs lack sufficient flexibility in adjusting roller position and controlling tension. Most rollers are fixed in position after installation, making real-time adjustment impossible based on the actual operating conditions of the conveyor belt. When the conveyor belt becomes loose due to prolonged use or experiences uneven tension due to different operating conditions, it is difficult to adjust the tension by easily changing the roller position. Slippage easily occurs between the conveyor belt and the rollers, not only reducing conveying efficiency but also accelerating wear on both, increasing equipment maintenance frequency and costs. Frequent downtime for repairs can also cause production interruptions, resulting in economic losses for the company. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a belt conveyor roller that is easy to adjust tension, increases conveying efficiency and service life.

[0005] This utility model discloses a belt conveyor roller, comprising:

[0006] The installation mechanism is independently and fixedly installed.

[0007] Two mounting brackets are symmetrically installed at both ends of the mounting mechanism, and the mounting brackets are provided with inner grooves;

[0008] Two movable parts are respectively set in the inner grooves of two mounting brackets, and the movable parts are slidably installed along the length of the inner grooves. The movable parts are provided with support shafts.

[0009] The roller body has mounting shafts at both ends, and the axes of the two mounting shafts coincide. The two mounting shafts are coaxially installed with two support shafts.

[0010] Two adjustment mechanisms are installed on two mounting brackets respectively, and the adjustment mechanisms are installed in conjunction with the moving parts. The adjustment mechanisms are used to adjust the position of the moving parts in the groove of the mounting bracket.

[0011] Furthermore, the regulatory body includes:

[0012] The threaded rod is rotatably mounted on the mounting bracket at one end, and the axis of rotation of the threaded rod is parallel to the movement trajectory of the moving part. The threaded rod is installed in the threaded inner hole of the moving part, and an extension post is provided at the other end of the threaded rod.

[0013] The transmission component is rotatably mounted on the mounting bracket, and the transmission component is coaxially mounted with the threaded rod. The extension column is installed in the through hole of the transmission component, and the extension column rotates synchronously with the transmission component. The transmission component is slidably mounted along the length of the extension column.

[0014] The connector is coaxially mounted on the extension column, and the connector is located in the inner cavity of the transmission component;

[0015] The spring has its two ends connected to the inner walls of the connecting component and the transmission component, respectively.

[0016] Two limit mechanisms are installed on two mounting brackets. The limit mechanisms are used to limit the rotation of the transmission components.

[0017] As a preferred option, the limiting mechanism includes:

[0018] The limit seat is installed in the inner groove of the mounting bracket, and the limit seat is coaxially installed with the transmission component. The limit seat is provided with a group of positioning holes.

[0026] As a preferred option, the base is provided with a keyway hole.

[0027] Furthermore, the mounting shaft and the support shaft are slidably mounted along their long sections, and the support shaft is provided with a chamfer.

[0028] This design incorporates a belt conveyor roller with an independently fixed mounting mechanism that provides robust support for the entire roller system, ensuring operational stability.

[0036] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0037] This utility model relates to a belt conveyor roller, such as Figures 1 to 6 As shown, it includes:

[0038] Mounting mechanism 1 is independently and fixedly installed to support the entire roller system;

[0039] Two mounting brackets 2 are symmetrically installed at both ends of the mounting mechanism 1. The mounting brackets 2 are provided with inner grooves, and the length direction of the inner grooves is perpendicular to the axis of the roller.

[0040] Two movable parts 3 are respectively set in the inner grooves of two mounting brackets 2, and the movable parts 3 are slidably installed along the length of the inner groove. A support shaft 4 is provided on the movable parts 3.

[0041] The roller body 5 has mounting shafts 6 at both ends, and the axes of the two mounting shafts 6 coincide. The two mounting shafts 6 are coaxially mounted with the two support shafts 4, so that the roller body 5 can rotate freely on the support shafts 4. The surface of the roller body 5 is covered with rubber or other wear-resistant materials to increase friction and extend service life.

[0042] Two adjustment mechanisms 7 are respectively installed on two mounting brackets 2, and the adjustment mechanisms 7 are installed in conjunction with the moving parts 3. The adjustment mechanisms 7 are used to adjust the position of the moving parts 3 in the inner groove of the mounting bracket 2.

[0043] The working principle of this device is as follows:

[0044] During operation, the roller body 5 can rotate freely on the support shaft 4 through the cooperation of the mounting shaft 6 and the support shaft 4. When the conveyor belt is running, the roller body 5 rotates accordingly, driving the conveyor belt to run smoothly. Through the adjustment mechanism 7, the position of the moving part 3 in the inner groove can be adjusted, thereby changing the position of the roller body 5 to adjust the tension of the roller body 5.

[0045] The mounting mechanism 1 is independently fixed, providing stable support for the entire roller system and ensuring the stability of system operation. The mounting brackets 2, symmetrically installed at both ends of the mounting mechanism 1, have inner grooves that provide a specific track for the sliding of the moving part 3. The design of the inner groove length direction being perpendicular to the axis of the roller body 5 allows the moving part 3 to precisely affect the position of the roller body 5. The moving part 3 can slide along the length direction of the inner groove. Its support shaft 4 is coaxially installed with the mounting shaft of the roller body 5, enabling the roller body 5 to rotate freely on the support shaft 4. This ensures that the roller body 5 can smoothly follow the rotation when the conveyor belt is running, driving the conveyor belt to run smoothly. The surface of the roller body 5 is covered with rubber or other wear-resistant materials, which increases the friction between it and the conveyor belt, making the conveyor belt run more stably, and also extends the service life of the roller body 5, reducing replacement costs. The adjustment mechanism 7 works with the moving part 3 to adjust the position of the moving part 3 in the inner groove, thereby changing the position of the roller body 5 and realizing flexible adjustment of the roller tension to adapt to different working requirements and changes in working conditions, improving the working efficiency and adaptability of the belt conveyor.

[0046] As a preferred option, such as Figures 1 to 5 As shown, the adjustment mechanism 7 includes:

[0047] The threaded rod 71 is rotatably mounted on the mounting bracket 2 at one end, and the rotation axis of the threaded rod 71 is parallel to the movement trajectory of the moving part 3. The threaded rod 71 is installed in the threaded inner hole of the moving part 3, and the other end of the threaded rod 71 is provided with an extension post 72.

[0048] The transmission component 73 is rotatably mounted on the mounting bracket 2, and the transmission component 73 is coaxially mounted with the threaded rod 71. The extension column 72 is installed in the through hole of the transmission component 73, and the extension column 72 rotates synchronously with the transmission component 73. The transmission component 73 is slidably mounted along the length direction of the extension column 72.

[0049] The connector 74 is coaxially mounted on the extension column 72, and the connector 74 is located in the inner cavity of the transmission member 73;

[0050] Spring 75 has its two ends connected to the inner walls of connector 74 and transmission component 73, respectively;

[0051] Two limiting mechanisms 76 are installed on two mounting brackets 2. The limiting mechanisms 76 are used to limit the rotation of the transmission component 73.

[0052] The rotation axis of the threaded rod 71 is parallel to the movement trajectory of the moving part 3 and is installed in the threaded inner hole of the moving part 3. When the threaded rod 71 rotates, it can accurately convert the rotational motion into the linear motion of the moving part 3 along the inner groove, realizing the precise adjustment of the position of the roller body 5. The cooperation between the extension column 72 and the transmission part 73 allows the transmission part 73 to drive the extension column 72 to rotate synchronously and slide along its length. The limiting mechanism 76 limits the rotation of the transmission part 73, stabilizing the rotation process of the roller body 5 and preventing displacement. The setting of the connecting part 74 and the spring 75 provides the reset power after the relative displacement of the transmission part 73 and the extension part 72. The movement of the position of the transmission part 73 releases the rotation limit of the transmission part 73 by the limiting mechanism 76, increasing the convenience of adjusting the rotation of the threaded rod 71, while increasing the working stability and ensuring the smooth operation of the conveyor belt.

[0053] As a preferred option, such as Figures 1 to 5 As shown, the limiting mechanism 76 includes:

[0054] The limiting seat 76a is installed in the inner groove of the mounting bracket 2, and the limiting seat 76a is coaxially installed with the transmission component 73. The limiting seat 76a is provided with a positioning hole group, which is evenly distributed along the circumference of the limiting seat 76a.

[0055] The limiting pin 76b is installed on the outer wall of the transmission component 73, and the limiting pin 76b is connected to the positioning hole group of the limiting seat 76a to realize the rotation limit of the transmission component 73.

[0056] The limiting seat 76a is installed in the inner groove of the mounting frame 2 and is coaxial with the transmission component 73. The positioning holes evenly distributed along the circumference on it are precisely matched with the limiting pins 76b installed on the outer wall of the transmission component 73. During normal operation, the limiting pins 76b are inserted into the positioning holes, effectively preventing the transmission component 73 from rotating accidentally, thereby ensuring the stable position of the roller body 5 and preventing roller displacement caused by external force impact or equipment vibration during the operation of the conveyor belt, thus ensuring the smooth operation of the conveyor belt. When it is necessary to adjust the position of the roller body 5, simply drive the transmission component 73 to disengage the limiting pins 76b from the positioning holes, and the limiting can be easily released, allowing the threaded rod 71 to rotate freely, realizing the sliding of the moving part 3 and the adjustment of the roller position. The operation is simple and precise, ensuring the stability of the roller in daily operation and taking into account the flexibility during adjustment, significantly improving the working reliability and adaptability of the belt conveyor.

[0057] As a preferred option, such as Figures 1 to 5 As shown, the transmission component 73 is provided with a regular polygonal inner hole;

[0058] The regular polygonal inner hole facilitates operation with tools and facilitates the driving of the extension column 72, thereby improving the maintenance efficiency of the equipment.

[0059] As a preferred option, such as Figures 1 to 2 As shown, the installation mechanism 1 includes:

[0060] The base 11 has fasteners 12 symmetrically arranged at both ends, and the fasteners 12 are provided with threaded holes;

[0062] Two bolts 14 pass through the slots in the two mounting plates 13 respectively, and are installed by engaging with the threaded holes in the two fasteners 12;

[0063] The symmetrically arranged fixing parts 12 at both ends of the base 11, along with their threaded holes, provide a stable installation foundation for the entire mechanism, ensuring firm fixation under various working conditions. The two mounting plates 13 precisely match the assembly slots of the fixing parts 12, which not only facilitates the installation of the mounting frame 2 but also ensures the stability of the installation, enabling the mounting frame 2 to reliably support the roller-related components. The bolts 14 pass through the slots of the mounting plates 13 and engage with the threaded holes of the fixing parts 12 for installation. This connection method is simple to operate, easy to install and disassemble, and greatly improves the assembly and maintenance efficiency of the equipment.

[0064] As a preferred option, such as Figures 1 to 3 As shown, a guide rail 15 is provided on the mounting plate 13, and the guide rail 15 is slidably installed with the guide groove of the fixing member 12.

[0065] The cooperation between the guide rail 15 and the guide groove provides precise guidance for the installation of the mounting plate 13, enabling the mounting plate 13 to be quickly and accurately assembled with the fixing part 12, which significantly improves the installation efficiency. At the same time, during the operation of the equipment, this sliding installation structure can effectively constrain the position of the mounting plate 13, ensuring that it will not shift or shake, thereby ensuring the stability of the mounting frame 2 and the entire roller system.

[0066] As a preferred option, such as Figure 1 As shown, the base 11 is provided with a keyway hole;

[0067] The keyway design increases the flexibility of the installation method, enabling the equipment to better adapt to different working environments and installation conditions, and improving the versatility and reliability of the belt conveyor roller mounting mechanism.

[0068] As a preferred option, such as Figures 1 to 6 As shown, the mounting shaft 6 and the support shaft 4 are slidably mounted along the long section, and the support shaft 4 is provided with a chamfer;

[0069] The sliding installation method of the mounting shaft 6 and the support shaft 4 makes the installation and disassembly of the roller body 5 more convenient and efficient, enabling the rapid completion of equipment assembly and maintenance, effectively saving time and labor costs. The chamfer on the support shaft 4 plays a good guiding role when the mounting shaft 6 and the support shaft 4 are engaged, reducing the installation difficulty.

[0070] The belt conveyor roller of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.
