Description

Technical Field

[0001] This utility model relates to the field of belt tensioners, and more particularly to tensioner assemblies for adjusting belt drives. Background Technology

[0002] The tensioner pulley is an important component in a belt drive system. It is mainly used to adjust the tension of the belt to ensure the normal operation of the belt drive. The tensioner pulley presses on the belt to change the wrap angle of the pulley or control the tension of the belt, thereby ensuring that the belt will not slip due to slack during operation.

[0003] Common tension pulleys are typically adjusted by springs or hydraulic pressure to regulate belt tension. However, they lack cleaning components and cannot clean both sides of the drive belt simultaneously, making it easy for debris to stick to the belt surface. When a belt with debris passes over the tension pulley, it can affect the normal operation of the pulley and even cause the belt to slip off, thus reducing the safety and practicality of the belt tension pulley.

[0004] Therefore, to address the lack of a cleaning component in the aforementioned tensioning pulley for adjusting belt drives, which prevents simultaneous cleaning of both sides of the transmission belt, a tensioning pulley assembly for belt drive adjustment can be designed. By rotating the adjusting rod, a bidirectional lead screw can be driven to rotate. When the bidirectional lead screw rotates, it will cause the two moving blocks inside the first adjusting seat to move closer together. The movement of the moving blocks will cause the two brush plates on their front sides to move synchronously. The movement of the brush plates will cause the brush heads on their lower sides to contact the upper and lower sides of the transmission belt, thereby achieving the effect of cleaning the sides of the transmission belt. Utility Model Content

[0005] To address the common issue that tension pulleys lack cleaning components and cannot simultaneously clean both sides of the drive belt, which easily leads to debris adhering to the belt surface, when the belt with debris passes over the tension pulley, it can affect the normal use of the tension pulley and even cause the belt to slip off, thus reducing the safety and practicality of the belt tension pulley.

Two brush plates are symmetrically connected to the front side of the moving blocks.

[0007] Preferably, rotating the adjusting rod can drive the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it will cause the two moving blocks inside the first adjusting seat to move closer to each other. The movement of the moving blocks will cause the two brush plates in front of them to move synchronously. The movement of the brush plates will cause the brush head on its lower side to contact the upper and lower sides of the transmission belt, thereby achieving the effect of cleaning the side of the transmission belt. At the same time, the movement of the brush plates will cause the two moving blocks inside the second adjusting seat to move outside the slide rod, so as to improve the stability of the brush plate movement.

[0008] Preferably, the front sides of the first mounting plate and the second mounting plate are symmetrically provided with two sliding grooves, and the inside of the sliding grooves is symmetrically provided with two limiting sliders.

[0009] Preferably, an electric telescopic rod is connected to the lower rear end of the limiting slider, and a support plate is installed on the lower rear end of the first mounting plate and the second mounting plate corresponding to the position of the electric telescopic rod. The bottom of the electric telescopic rod is connected to the top of the support plate.

[0010] Preferably, two connecting posts are symmetrically installed at the front ends of the two limiting sliders, and a tensioning wheel body is provided between the first mounting plate and the second mounting plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. Rotating the adjusting rod can drive the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it will cause the two moving blocks inside the first adjusting seat to move closer to each other. The movement of the moving blocks will cause the two brush plates in front of them to move synchronously. The movement of the brush plates will cause the brush head on the lower side to contact the upper and lower sides of the transmission belt, thereby achieving the effect of cleaning the side of the transmission belt. At the same time, the movement of the brush plates will cause the two moving blocks inside the second adjusting seat to move outside the slide rod, so as to improve the stability of the brush plate movement.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a tensioning pulley assembly for adjusting a belt drive, including a first mounting plate 1 and a second mounting plate 2; it also includes a first adjusting seat 3, a second adjusting seat 4, a moving groove 5, a limiting block 6, a moving block 7, a bidirectional lead screw 8, an adjusting rod 9, a sliding rod 10, and a brush plate 11. The first adjusting seat 3 and the second adjusting seat 4 are symmetrically mounted on the lower front side of the first mounting plate 1. The moving groove 5 is symmetrically opened on the inner side of the first adjusting seat 3 and the second adjusting seat 4. Four limiting blocks 6 are symmetrically arranged at the upper and lower ends inside the moving groove 5. Four moving blocks 7 are symmetrically connected to the outer side of the limiting blocks 6. The bidirectional lead screw 8 is arranged on the inner side of the first adjusting seat 3. The upper and lower ends of the bidirectional lead screw 8 are connected to the moving blocks 7 on the inner side of the first adjusting seat 3. The top of the first adjusting seat 3 is connected to the adjusting rod 9. The end passes through the first adjusting seat 3 and is connected to the bidirectional lead screw 8. The inner side of the second adjusting seat 4 is provided with a slide rod 10. The upper and lower ends of the slide rod 10 are connected to the moving block 7 inside the second adjusting seat 4. Two brush plates 11 are symmetrically connected to the front side of the moving block 7. By rotating the adjusting rod 9, the bidirectional lead screw 8 can be rotated. When the bidirectional lead screw 8 rotates, it will cause the two moving blocks 7 inside the first adjusting seat 3 to move closer to each other. The movement of the moving block 7 will cause the two brush plates 11 on its front side to move synchronously. The movement of the brush plate 11 will cause the brush head on its lower side to contact the upper and lower sides of the transmission belt 18, thereby achieving the effect of cleaning the side of the transmission belt 18. At the same time, the movement of the brush plate 11 will cause the two moving blocks 7 inside the second adjusting seat 4 to move outside the slide rod 10, so as to improve the stability of the brush plate 11 when it moves.

[0023] Please see Figures 1-4 In this embodiment, two symmetrical grooves 12 are formed on the front sides of the first mounting plate 1 and the second mounting plate 2, and two limiting sliders 13 are symmetrically arranged inside the grooves 12. The limiting sliders 13 can move up and down at the upper ends of the first mounting plate 1 and the second mounting plate 2 through the grooves 12. An electric telescopic rod 14 is connected to the lower rear end of the limiting slider 13. A support plate 15 is installed at the lower rear end of the first mounting plate 1 and the second mounting plate 2 corresponding to the position of the electric telescopic rod 14. The bottom of the electric telescopic rod 14 is connected to the top of the support plate 15. The support plate 15 can be used to control the electric telescopic rod. The bottom of the 14 is supported, and the electric telescopic rod 14 can drive the limiting slider 13 to move up and down inside the slide groove 12. Two connecting columns 16 are symmetrically installed at the front ends of the two limiting sliders 13. A tension wheel body 17 is provided between the first mounting plate 1 and the second mounting plate 2. The two connecting columns 16 are connected to the front and rear sides of the tension wheel body 17. The connecting columns 16 can drive the limiting slider 13 to move synchronously with the tension wheel body 17. When the tension wheel body 17 moves upward, it will increase the tension of the transmission belt 18, thereby preventing the transmission belt 18 from slipping due to slack during operation.

[0024] Please see Figures 1-4 In this embodiment, a transmission belt 18 is provided on the upper side of the tensioning wheel body 17. A main transmission wheel 19 is provided on the inner left end of the transmission belt 18, and a secondary transmission wheel 20 is provided on the inner right end of the transmission belt 18. The transmission belt 18 can be driven to perform transmission work through the main transmission wheel 19 and the secondary transmission wheel 20. Limiting grooves are opened on the left and right sides inside the slide groove 12. The left and right ends of the limiting slider 13 are slidably connected to the slide groove 12 through the limiting grooves. By inserting the two ends of the limiting slider 13 into the limiting grooves, the stability of the movement of the limiting slider 13 can be improved. Two brush plates 11 are located on the upper and lower sides of the transmission belt 18, and the brush plates 11 are components made of nylon material. The two brush plates 11 can clean the upper and lower sides of the transmission belt 18 at the same time. Moreover, the brush plates 11 made of nylon material can make them more wear-resistant and more elastic.

[0025] During operation, the main drive wheel 19 and the auxiliary drive wheel 20 drive the drive belt 18 for transmission. Simultaneously, the support plate 15 supports the bottom of the electric telescopic rod 14. The electric telescopic rod 14 drives the limiting slider 13 to move up and down within the slide groove 12. When the limiting slider 13 moves, it causes the connecting column 16 and the tension wheel body 17 to move synchronously. When the tension wheel body 17 moves upward, it increases the tension of the drive belt 18, thus preventing the drive belt 18 from slipping due to slack during operation. Rotating the adjusting rod 9 can drive the bidirectional lead screw 8 to rotate. When the bidirectional lead screw 8 rotates, it will cause the two moving blocks 7 on the inner side of the first adjusting seat 3 to move closer to each other. The movement of the moving blocks 7 will cause the two brush plates 11 on their front side to move synchronously. The movement of the brush plates 11 will cause the brush head on its lower side to contact the upper and lower sides of the transmission belt 18, thereby achieving the effect of cleaning the side of the transmission belt 18. At the same time, the movement of the brush plates 11 will cause the two moving blocks 7 on the inner side of the second adjusting seat 4 to move outside the slide rod 10, so as to improve the stability of the brush plates 11 when they move.

[0026] Through the above steps, rotating the adjusting rod 9 can drive the bidirectional lead screw 8 to rotate. When the bidirectional lead screw 8 rotates, it will drive the two moving blocks 7 inside the first adjusting seat 3 to move closer to each other. The movement of the moving blocks 7 will drive the two brush plates 11 on their front side to move synchronously. The movement of the brush plates 11 will cause the brush head on its lower side to contact the upper and lower sides of the transmission belt 18, thereby achieving the effect of cleaning the sides of the transmission belt 18. At the same time, the movement of the brush plates 11 will drive the two moving blocks 7 inside the second adjusting seat 4 to move outside the slide rod 10, thereby improving the stability of the movement of the brush plates 11. This solves the problem of common tensioning pulleys, which are usually adjusted by springs or hydraulic pressure to adjust the height of the tensioning pulley. They can adjust the belt tension, but lack cleaning components and cannot clean both sides of the transmission belt 18 at the same time. This can easily cause debris to stick to the surface of the belt. When the belt with debris passes through the tensioning pulley, it will affect the normal use of the tensioning pulley and may even cause the belt to slip, thereby reducing the safety and practicality of the belt tensioning pulley.
