Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering, and in particular to a rubber conveyor belt tension adjustment device. Background Technology

[0002] In modern industrial production, rubber conveyor belts, as a highly efficient and reliable continuous material conveying equipment, are widely used in many industries such as mining, ports, power, chemical industry, and food processing. They can transport various bulk materials and packaged goods from one location to another in a continuous and stable manner, greatly improving production efficiency and reducing labor costs and labor intensity. They are an indispensable and important component of modern industrial automated production processes.

[0003] Existing methods for adjusting the tension of rubber conveyor belts typically involve manually rotating a screw to move an adjusting roller, thereby changing the tension. However, this method lacks precise quantitative control, and operators often rely on experience to roughly judge the tension, making it difficult to achieve accurate tension adjustment. Furthermore, during conveyor belt operation, factors such as material impact, vibration, and the equipment's own operation can cause the screw to loosen, leading to changes in the position of the adjusting roller and consequently altering the conveyor belt tension.

[0004] Therefore, it is necessary to design a rubber conveyor belt tension adjustment device that can precisely adjust the tension and lock the screw to prevent accidental contact with the screw or movement of the adjustment roller due to wear and loosening of the screw. Utility Model Content

[0005] To overcome the shortcomings of existing rubber conveyor belt tension adjustment methods, which rely on operators' experience to roughly judge the tension, making precise adjustment difficult, and the fact that during conveyor belt operation, factors such as material impact, vibration, and equipment operation can cause the screw to loosen, leading to changes in the position of the adjusting roller and consequently altering the conveyor belt tension, this invention provides a rubber conveyor belt tension adjustment device that can precisely adjust the tension and lock the screw to prevent accidental screw contact or movement of the adjusting roller due to screw wear and loosening.

[0006] The technical solution of this utility model is: a rubber conveyor belt tension adjustment device, including a base frame, a conveyor belt, a mounting frame, a motor, a drive roller, a transmission component, a driven wheel, and an adjustment component. The drive roller is rotatably connected to the upper left part of the base frame, and the driven wheel is rotatably connected to the upper right part of the base frame. The conveyor belt is wound between the driven wheel and the drive roller. The mounting frame is connected to the lower left side of the base frame, and the motor is connected to the upper side of the mounting frame. A transmission component is provided between the motor output shaft and the drive roller. An adjustment component that can accurately adjust the tension and prevent loosening is provided at the front of the base frame.

[0007] Optionally, the transmission assembly includes pulleys and a flat belt, with pulleys connected to both the motor output shaft and the drive roller, and a flat belt wound between the pulleys.

[0008] Optionally, it also includes an adjustment assembly, which includes a first fixed frame, a screw, a scale rod, a connecting frame, a connecting shaft, an adjusting roller, and a locking nut. The first fixed frame is connected to both the front and rear sides of the base frame. The screw is threadedly connected to the front first fixed frame. The scale rod is connected to the first fixed frame. The connecting frame is slidably connected to the lower part of the scale rod. The screw is rotatably connected to the adjacent connecting frame. The connecting shaft is connected between the lower parts of the connecting frames. The connecting shaft is slidably connected to the first fixed frame. The adjusting roller is rotatably connected to the connecting shaft. The adjusting roller is in contact with the conveyor belt. Locking nuts are threadedly connected to both the front and rear parts of the connecting shaft. The locking nuts are in contact with the adjacent first fixed frame.

[0009] Optionally, it also includes a knob, which is connected to the upper side of the screw.

[0010] Optionally, the knob is textured for a non-slip grip.

[0011] Optionally, it also includes a second fixed frame, a cleaning roller, and springs. Two second fixed frames are connected to the connecting shaft. A connecting member is slidably provided between the lower parts of the second fixed frames. A cleaning roller is rotatably connected to the connecting member. The cleaning roller contacts the conveyor belt. Two springs are connected between the second fixed frame and the connecting member.

[0012] The beneficial effects of this utility model are: 1. This utility model moves the screw downward, which drives the adjusting roller downward. The adjustment is made according to the distance the connecting frame moves on the scale rod. Then, the locking nut is rotated and tightened so that the locking nut contacts the first fixed frame for locking. This achieves the effect of accurately adjusting the tension and locking the screw to prevent accidental contact with the screw or movement of the adjusting roller due to wear and loosening of the screw.

[0013] 2. This utility model uses a spring to keep the cleaning roller close to the conveyor belt. When the motor is started, the drive roller is driven to rotate through the pulley and flat belt on the transmission component. This causes the conveyor belt, driven wheel and adjusting roller to rotate, which in turn causes the cleaning roller to rotate. The cleaning roller cleans the surface of the conveyor belt, thus achieving the goal of cleaning the conveyor belt while transporting materials, and avoiding the accumulation of impurities on the conveyor belt that would affect the conveying effect.

Detailed Implementation

[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] A rubber conveyor belt tension adjustment device, such as Figures 1-3 As shown, it includes a base frame 1, a conveyor belt 2, a mounting frame 3, a motor 4, a drive roller 5, a transmission assembly 6, a driven wheel 7, and an adjustment assembly. The drive roller 5 is rotatably connected to the upper left of the base frame 1, and the driven wheel 7 is rotatably connected to the upper right of the base frame 1. The conveyor belt 2 is wound between the driven wheel 7 and the drive roller 5. The mounting frame 3 is connected to the lower left of the base frame 1, and the motor 4 is connected to the upper side of the mounting frame 3. The transmission assembly 6 is provided between the output shaft of the motor 4 and the drive roller 5. An adjustment assembly is provided at the front of the base frame 1.

[0021] like Figures 1-3 As shown, the transmission assembly 6 includes pulleys and a flat belt. The output shaft of the motor 4 and the drive roller 5 are both connected to pulleys, and a flat belt is wound between the pulleys.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, it also includes an adjustment assembly, which includes a first fixed frame 8, a screw 9, a knob 10, a scale rod 11, a connecting frame 12, a connecting shaft 13, an adjusting roller 131, and a locking nut 14. The base frame 1 is connected to the first fixed frame 8 on both the front and rear sides. The screw 9 is threadedly connected to the first fixed frame 8 at the front. The knob 10 is connected to the upper side of the screw 9. The knob 10 has anti-slip texture for easy gripping. The scale rod 11 is connected to the first fixed frame 8. The connecting frame 12 is slidably connected to the lower part of the scale rod 11. The screw 9 is rotatably connected to the adjacent connecting frame 12. The connecting shaft 13 is connected between the lower parts of the connecting frames 12. The connecting shaft 13 is slidably connected to the first fixed frame 8. The adjusting roller 131 is rotatably connected to the connecting shaft 13. The adjusting roller 131 is in contact with the conveyor belt 2. The locking nut 14 is threadedly connected to both the front and rear parts of the connecting shaft 13. The locking nut 14 is in contact with the adjacent first fixed frame 8.

[0023] like Figure 4 As shown, it also includes a second fixed frame 15, a cleaning roller 16 and a spring 17. Two second fixed frames 15 are connected to the connecting shaft 13.

[0024] When using this device, first place the base frame 1 in the material conveying area, then hold and rotate the knob 10 to move the screw 9 downwards under the action of the thread, driving the connecting frame 12 and the adjusting roller 131 downwards, causing the connecting shaft 13 to move downwards on the first fixed frame 8. Adjust the adjusting roller 131 according to the distance the connecting frame 12 moves on the scale bar 11. The greater the downward movement of the adjusting roller 131, the greater the tension of the conveyor belt 2. After adjustment, connect the locking nut 14 to the connecting shaft 13, and then rotate and tighten the locking nut 14 so that the locking nut 14 contacts the first fixed frame 8 for locking, thereby enabling precise adjustment of the tension and allowing for adjustment of the screw 9. Locking is performed to prevent accidental contact with screw 9 or movement of adjusting roller 131 due to wear and loosening of screw 9. As the second fixing frame 15 moves downward, it drives cleaning roller 16 downward. Spring 17 makes cleaning roller 16 stick to conveyor belt 2. Then, motor 4 on mounting frame 3 is started, driving pulley to rotate. Through pulley on transmission assembly 6 and flat belt transmission, driving drive roller 5 to rotate, causing conveyor belt 2, driven pulley 7 and adjusting roller 131 to rotate, causing cleaning roller 16 to rotate. Cleaning roller 16 cleans the surface of conveyor belt 2, thereby cleaning conveyor belt 2 while transporting materials, and preventing impurities from sticking to conveyor belt 2 and affecting the conveying.
