[0034] There are two fixed frames 2 and two belt surface limiting frames 3, which are symmetrically arranged on both sides of the upper end of the flat belt conveyor frame 1, and the belt surface limiting frames 3 are "L" shaped.

[0035] The opposite surfaces of the two second brackets 7 are rotatably connected with a cleaning roller 16, and a plurality of cleaning bristles 17 are evenly and fixedly connected to the surface of the cleaning roller 16. The end of the cleaning bristles 17 close to the flat belt conveyor 4 is in contact with the flat belt conveyor 4. The cleaning roller 16 rotates through the second bracket 7 on the rear side and is fixedly connected with a first pulley 18. The interior of the flat belt conveyor 4 is rotatably connected with a conveyor belt drive shaft 19, which rotates through the corresponding fixed frame 2 and is fixedly connected with a second pulley 20. The surfaces of the first pulley 18 and the conveyor belt drive shaft 19 are transmission-connected with a belt 21.

[0036] The inner wall of the flat belt conveyor frame 1 is rotatably connected with a plurality of first conveyor belt guide rollers 8, which are in contact with the belt surface of the flat belt conveyor 4; two first brackets 6 are fixedly connected at symmetrical positions on the surface of the flat belt conveyor frame 1; two second conveyor belt guide rollers 9 are rotatably connected to the opposite surfaces of the two first brackets 6, which are in contact with the belt surface of the flat belt conveyor 4; third conveyor belt guide rollers 10 are rotatably connected to the opposite surfaces of the two first brackets 6, which are in contact with the belt surface of the flat belt conveyor 4; a first driving motor 11 is fixedly connected to the surface of the front first bracket 6; a rotating shaft 12 is rotatably connected to the opposite surfaces of the two first brackets 6; two connecting frames 13 are fixedly connected to the surface of the two connecting frames 13; tensioning rollers 14 are rotatably connected to the insides of the two connecting frames 13; through grooves 15 are provided on the surfaces of the two first brackets 6, and the two tensioning rollers 14 are slidably connected to the two through grooves 15.

[0037] When using the flat belt conveyor, first place the product to be conveyed on the surface of the flat belt conveyor 4, and the flat belt conveyor frame 1 starts the flat belt conveyor 4 to convey the product. In the process of the flat belt conveyor 4 conveying the product, the conveyor belt driving shaft 19 will drive the second pulley 20 to rotate, and the second pulley 20 drives the belt 21 to rotate, and the belt 21 drives the first pulley 18 and the cleaning roller 16 to rotate, and the cleaning roller 16 drives the cleaning brush 17 to rotate to clean the belt surface of the flat belt conveyor 4. Through the connection of the belt 21, the cleaning roller 16 and the flat belt conveyor 4 have the same rotation direction, and the cleaning roller 16 and the flat belt conveyor 4 are arranged up and down so that the contact position between the cleaning brush 17 and the flat belt conveyor 4 rotates relatively, so that the cleaning brush 17 can clean the belt surface of the flat belt conveyor 4, improve the cleanliness of the flat belt conveyor 4, and prevent the flat belt conveyor 4 from accumulating dust during long-term use, causing the dust on the surface of the flat belt conveyor 4 to adhere to the surface of the product, thereby affecting the quality of the product and improving the quality of the product.

[0038] By using the first conveyor belt guide roller 8, the second conveyor belt guide roller 9, and the third conveyor belt guide roller 10, it is convenient to guide the belt surface of the flat belt conveyor 4. At the same time, the first drive motor 11 is started to drive the rotating shaft 12 and the connecting frame 13 to rotate. The connecting frame 13 drives the tensioning roller 14 to slide on the inner wall of the corresponding through groove 15. The belt surface of the flat belt conveyor 4 is tensioned by the tensioning roller 14 to ensure that the flat belt conveyor 4 has a high tension, increase the friction between the belt surface of the flat belt conveyor 4 and the driving roller, prevent the flat belt conveyor 4 from slipping when conveying products, ensure that the flat belt conveyor 4 has a good conveying force, reduce the dynamic load in the conveyor belt, make the conveyor run more smoothly, and improve the stability of the flat belt conveyor 4 during operation.

[0039] Due to the long-term use of the flat belt conveyor 4 and the change in the position of the products when placed on the surface of the flat belt conveyor 4, the friction between the belt surface of the flat belt conveyor 4 and the driving roller changes, which makes the transmission relationship between the front and rear sides of the flat belt conveyor 4 change, which can easily cause the flat belt conveyor 4 to deviate. When conveying products, it is easy to cause the products to deviate, causing some products to spill and resulting in product waste.

[0040] The belt surface of the flat belt conveyor 4 is limited by the belt surface limiting frame 3 and the conveyor belt correcting block 25, so that the flat belt conveyor 4 can be corrected in time when the belt skin of the flat belt conveyor 4 deviates. The fixed block 5 is limited by the belt surface limiting frame 3. When the flat belt conveyor 4 deviates, the fixed block 5 can be limited, so that the fixed block 5 can be reset in time under the guidance of the belt surface limiting frame 3. When the flat belt conveyor 4 deviates, the flat belt conveyor 4 can be corrected to its original position by the conveyor belt correcting block 25. The second drive motor 22 is started to drive the bidirectional threaded rod 23 to rotate, and the bidirectional threaded rod 23 drives the conveyor belt correcting block 25 to move to both sides, so that the conveyor belt correcting block 25 contacts the fixed block 5, and the fixed block 5 is squeezed by the conveyor belt correcting block 25, so that the fixed block 5 returns to its original position, and the flat belt conveyor 4 is corrected. The circular arc chamfer of the conveyor belt correcting block 25 is convenient for guiding the fixed block 5.

[0041] Deviation will cause the conveyor to run unstably, affecting the speed and efficiency of material transportation. Deviation correction can ensure the stable operation of the conveyor, improve the speed and efficiency of product transportation, and thus improve the overall production efficiency. At the same time, deviation will cause the friction between the conveyor belt and components such as the frame and rollers to increase, accelerating the wear and aging of the conveyor belt, and may even tear the conveyor belt. Deviation will also increase the load and wear of other equipment. Deviation correction can reduce this friction and wear, and extend the service life of the conveyor belt and related equipment.

[0042] Furthermore, by using the belt surface limit frame 3 and the conveyor belt correction block 25, it is convenient to correct the deviated flat belt conveyor 4 to prevent some products from spilling from the flat belt conveyor 4 and causing product waste. The correction can ensure the stable operation of the conveyor, improve the speed and efficiency of product transportation, thereby improving the overall production efficiency. At the same time, the correction can reduce friction and wear with the frame, extend the service life of the conveyor belt and related equipment, and enhance the practicality of the device.

[0043] By sliding and rotating the tensioning roller 14 on the inner wall of the through groove 15, the belt surface of the flat belt conveyor 4 can be tensioned, the friction between the flat belt conveyor 4 and the belt driving roller can be increased, the stability of the flat belt conveyor 4 during operation can be improved, the transportation of products can be facilitated, and the dynamic load in the conveyor belt can be reduced, so that the operation of the conveyor is more stable, and the stability of the flat belt conveyor 4 during operation can be improved.

[0044] By rotating the cleaning bristles 17, it is convenient to clean the belt surface of the flat belt conveyor 4, thereby improving the cleanliness of the flat belt conveyor 4 and preventing the flat belt conveyor 4 from accumulating dust during long-term use, causing the dust on the surface of the flat belt conveyor 4 to adhere to the surface of the product, thereby affecting the quality of the product and improving the quality of the product.

[0045] Working principle: When using the flat belt conveyor, first place the product to be conveyed on the surface of the flat belt conveyor 4, and the flat belt conveyor frame 1 starts the flat belt conveyor 4 to convey the product. In the process of the flat belt conveyor 4 conveying the product, the conveyor belt drive shaft 19 will drive the second pulley 20 to rotate, and the second pulley 20 drives the belt 21 to rotate, and the belt 21 drives the first pulley 18 and the cleaning roller 16 to rotate, and the cleaning roller 16 drives the cleaning brush 17 to rotate to clean the belt surface of the flat belt conveyor 4. Through the connection of the belt 21, the cleaning roller 16 and the flat belt conveyor 4 have the same rotation direction, and the cleaning roller 16 and the flat belt conveyor 4 are arranged up and down so that the contact position between the cleaning brush 17 and the flat belt conveyor 4 rotates relatively, so that the cleaning brush 17 can clean the belt surface of the flat belt conveyor 4, improve the cleanliness of the flat belt conveyor 4, and prevent the flat belt conveyor 4 from accumulating dust during long-term use, causing the dust on the surface of the flat belt conveyor 4 to adhere to the surface of the product, thereby affecting the quality of the product and improving the quality of the product.

[0046] By using the first conveyor belt guide roller 8, the second conveyor belt guide roller 9, and the third conveyor belt guide roller 10, it is convenient to guide the belt surface of the flat belt conveyor 4. At the same time, the first drive motor 11 is started to drive the rotating shaft 12 and the connecting frame 13 to rotate. The connecting frame 13 drives the tensioning roller 14 to slide on the inner wall of the corresponding through groove 15. The belt surface of the flat belt conveyor 4 is tensioned by the tensioning roller 14 to ensure that the flat belt conveyor 4 has a high tension, increase the friction between the belt surface of the flat belt conveyor 4 and the driving roller, prevent the flat belt conveyor 4 from slipping when conveying products, ensure that the flat belt conveyor 4 has a good conveying force, reduce the dynamic load in the conveyor belt, make the conveyor run more smoothly, and improve the stability of the flat belt conveyor 4 during operation.

[0047] Due to the long-term use of the flat belt conveyor 4 and the change in the position of the products when placed on the surface of the flat belt conveyor 4, the friction between the belt surface of the flat belt conveyor 4 and the driving roller changes, which makes the transmission relationship between the front and rear sides of the flat belt conveyor 4 change, which can easily cause the flat belt conveyor 4 to deviate. When conveying products, it is easy to cause the products to deviate, causing some products to spill and resulting in product waste.

[0048] The belt surface of the flat belt conveyor 4 is limited by the belt surface limiting frame 3 and the conveyor belt correcting block 25, so that the flat belt conveyor 4 can be corrected in time when the belt skin of the flat belt conveyor 4 deviates. The fixed block 5 is limited by the belt surface limiting frame 3. When the flat belt conveyor 4 deviates, the fixed block 5 can be limited, so that the fixed block 5 can be reset in time under the guidance of the belt surface limiting frame 3. When the flat belt conveyor 4 deviates, the flat belt conveyor 4 can be corrected to its original position by the conveyor belt correcting block 25. The second drive motor 22 is started to drive the bidirectional threaded rod 23 to rotate, and the bidirectional threaded rod 23 drives the conveyor belt correcting block 25 to move to both sides, so that the conveyor belt correcting block 25 contacts the fixed block 5, and the fixed block 5 is squeezed by the conveyor belt correcting block 25, so that the fixed block 5 returns to its original position, and the flat belt conveyor 4 is corrected. The circular arc chamfer of the conveyor belt correcting block 25 is convenient for guiding the fixed block 5.

[0049] Deviation will cause the conveyor to run unstably, affecting the speed and efficiency of material transportation. Deviation correction can ensure the stable operation of the conveyor, improve the speed and efficiency of product transportation, and thus improve the overall production efficiency. At the same time, deviation will cause the friction between the conveyor belt and components such as the frame and rollers to increase, accelerating the wear and aging of the conveyor belt, and may even tear the conveyor belt. Deviation will also increase the load and wear of other equipment. Deviation correction can reduce this friction and wear, and extend the service life of the conveyor belt and related equipment.
