Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically an easy-to-install plastic idler roller for conveyor belts. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Idler rollers are an important component of conveyor belt systems, used to support the conveyor belt and reduce friction between the belt and the supporting structure.

[0003] Traditional idler roller installation methods are relatively complex, typically requiring tools for fixing, and are prone to positional deviations during installation, leading to unstable conveyor belt operation. Furthermore, the structure of traditional idlers is relatively simple, lacking effective limiting and fixing devices, which can cause the idlers to loosen or fall off during operation, affecting the normal operation of the conveyor belt. Therefore, there is an urgent need for an easy-to-install plastic idler roller for conveyor belts to solve these problems. Utility Model Content

After installation, the limiting mechanism 1 fixes the front end of the clamping plate 4, and the limiting mechanism 2 limits and fixes it on both sides of the clamping plate 4, thereby improving the fixing strength between the clamping plate 4 and the supporting sleeve 3, so as to install the roller body 2. The supporting sleeve 3 supports the roller body 2 to ensure its strength.

[0047] As one embodiment of this utility model, please refer to Figure 1 and Figure 2 The limiting mechanism includes:

[0048] The fixed threaded sleeve 5 is connected to the support sleeve 3;

[0049] Rotate the threaded sleeve 6 to connect it with the fixed threaded sleeve 5 via a thread;

[0050] Rotating sleeve 7 is rotatably connected to rotating threaded sleeve 6;

[0051] The connecting plate 8 is connected to the rotating sleeve 7 at one end and abuts against the clamping plate 4;

[0052] The abutment rod 9 is connected to the other end of the connecting plate 8 and engages with the slot 1.

[0053] In the initial state, the abutment rod 9 is not aligned with the mounting groove. After the clamping plate 4 and the support sleeve 3 are slidably abutted together, the rotating sleeve 7 is rotated, which in turn drives the abutment rod 9 to rotate, so that the abutment rod 9 is aligned with the first groove. The rotating threaded sleeve 6 is rotated, which drives the rotating sleeve 7 to move. The rotating sleeve 7 drives the abutment rod 9 to move, so that the abutment rod 9 is inserted into the first groove. The connecting plate 8 abuts against the clamping plate 4, thereby fixing the clamping plate 4.

[0054] As one embodiment of this utility model, please refer to Figures 1 to 4 The second limiting mechanism includes:

[0055] A fixing groove 10 is formed on the support sleeve 3. The fixing groove 10 and the second slot on the card plate 4 are located on the same horizontal line and are connected to each other.

[0056] The second fixing groove 20 is formed on the support sleeve 3. The second fixing groove 20 and the second slot on the card plate 4 are located on the same horizontal line and are connected to each other.

[0057] The inclined abutment plate 11 is slidably connected to the second slot and slidably engaged with the first fixed slot 10. The end of the inclined abutment plate 11 away from the support sleeve 3 is an inclined structure, and the end of the inclined structure abuts against the abutment rod 9.

[0058] The air groove 12 has one end connected to the inside of the fixed groove 10 and the other end connected to the inside of the fixed groove 20.

[0059] The spring-back assembly is located inside the fixing groove 10, with one end connected to the support sleeve 3 and the other end abutting against the inclined plate 11;

[0060] The snap-fit ​​assembly has one end connected to the spring-loaded assembly and the other end connected to the fixing slot 20.

[0061] The rebound assembly includes:

[0062] The fixing sleeve 13 is located inside the fixing groove 10 and is connected to the support sleeve 3;

[0063] The sliding rod 16 is slidably connected to the fixed sleeve 13;

[0064] The abutment plate 14 is connected to one end of the sliding rod 16 and abuts against the inclined abutment plate 11;

[0065] The elastic element 15 is connected at one end to the abutment plate 14 and at the other end to the fixing sleeve 13;

[0066] The snap-fit ​​assembly includes:

[0067] Piston 17 is connected to the other end of sliding rod 16 and is slidably engaged with fixed groove 10;

[0068] Piston 2 18 is located inside fixed groove 20 and is slidably engaged with it;

[0069] The lever 19 is connected to the piston 18 and engages with the slot 2.

[0070] During the insertion of the abutment rod 9 into the first slot, it presses the inclined abutment plate 11 to both sides. The inclined abutment plate 11 moves towards the side closer to the clamping plate 4. When the inclined abutment plate 11 moves to abut against the abutment plate 14, the inclined abutment plate 11 continues to move, pressing against the abutment plate 14. At the same time, the inclined abutment plate 11 moves to engage with the first fixing slot 10, fixing and limiting the clamping plate 4. The abutment plate 14 drives the sliding rod 16 to move, and the sliding rod 16 drives the piston 17 to move. The piston 17 compresses the air, causing the piston 2 18 to move. The piston 2 18 drives the clamping rod 19 to move, causing the clamping rod 19 to engage with the clamping plate 4, further limiting and fixing the clamping plate 4. The elastic element 15 ensures that the abutment plate 14 can return to its original position when the fixing is released. The elastic element 15 can be a spring, a sheet, etc.

[0071] The working principle of this utility model is as follows: In the initial state, the abutting rod 9 is not aligned with the mounting groove. When installing the roller body 2, after the clamping plate 4 and the supporting sleeve 3 are slidably abutted together, the rotating sleeve 7 is rotated, which in turn drives the abutting rod 9 to rotate, so that the abutting rod 9 is aligned with the first slot. The rotating threaded sleeve 6 is rotated, and the rotating threaded sleeve 6 drives the rotating sleeve 7 to move. The rotating sleeve 7 drives the abutting rod 9 to move, so that the abutting rod 9 is inserted into the first slot. The connecting plate 8 abuts against the clamping plate 4, thereby fixing the clamping plate 4. During the process of the abutting rod 9 being inserted into the first slot, it presses the inclined abutting plate to both sides. 11. The inclined abutment plate 11 moves towards the side closer to the clamping plate 4. When the inclined abutment plate 11 moves to abut against the abutment plate 14, the inclined abutment plate 11 continues to move and squeezes the abutment plate 14. At the same time, the inclined abutment plate 11 moves to engage with the fixing groove 10, fixing and limiting the clamping plate 4. The abutment plate 14 drives the sliding rod 16 to move. The sliding rod 16 drives the piston 17 to move. The piston 17 compresses the air, causing the piston 2 18 to move. The piston 2 18 drives the clamping rod 19 to move, causing the clamping rod 19 to engage with the clamping plate 4, further limiting and fixing the clamping plate 4.
