Description

Technical Field

[0001] This utility model relates to the field of belt conveyor manufacturing technology, and more specifically, to an energy-saving belt conveyor roller support structure. Background Technology

[0002] A belt conveyor is a mechanical device that continuously transports materials via a ring belt. It is widely used in industries such as mining, ports, and building materials. The body of a belt conveyor is usually equipped with rollers and tension regulating rollers. The rollers, as key transmission components, not only support the belt but also transmit driving force. The tension regulating rollers automatically compensate for belt slack through an elastic mechanism to ensure stable operation of the conveying system. The tension regulating rollers are in long-term frictional contact with the belt, making them prone to becoming accumulation points for dust and impurities.

[0003] Due to the dusty working environment and material residue on the belt surface, fine particles will continuously adhere to the adjusting roller during rotation. These accumulated impurities will reduce the friction coefficient of the roller surface, leading to an increase in belt slippage rate and a decrease in transmission efficiency. More seriously, hard particles can easily scratch the belt surface, accelerate belt wear, and shorten the service life of the equipment. Traditional manual cleaning methods have problems such as downtime affecting production and untimely cleaning. On the other hand, existing automatic cleaning devices installed on the conveyor body often require an additional power source, which not only increases energy consumption, but their complex structure also reduces system reliability. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving belt conveyor roller support structure to solve the problems mentioned in the background art.

[0005] Traditional manual cleaning of tension regulating rollers has problems such as downtime affecting production and untimely cleaning, while existing automatic cleaning devices installed on the conveyor body often require an additional power source.

[0006] To address the above problems, this utility model aims to provide an energy-saving belt conveyor roller support structure, including an assembly frame. A roller bracket for mounting three rollers is fixedly installed on the top of the assembly frame. A roller frame is slidably mounted on the lower side of the assembly frame. An adjusting roller is rotatably mounted on the roller frame. An elastic adjustment mechanism is provided between the roller frame and the assembly frame. Mounting frames are fixedly connected to both sides of the roller frame, and these mounting frames are connected to the interior of the roller frame. Synchronous pulleys are rotatably mounted inside the mounting frames. A synchronous belt drives two of the synchronous pulleys. A cleaning component is provided on the outer side of the synchronous belt, located above the adjusting roller. A transmission component is provided between the adjusting roller and one of the synchronous pulleys. When the adjusting roller rotates, it drives the corresponding synchronous pulley to rotate via the transmission component, causing the synchronous belt to drive the cleaning component to move along the axis of the adjusting roller. The cleaning component, now below the synchronous belt, cleans the circumferential sidewalls of the adjusting roller.

[0007] As a further improvement to this technical solution, the transmission assembly includes a gearbox fixedly mounted on the outer wall of the roller frame. The input shaft of the gearbox is coaxially and fixedly connected to the adjusting roller via a coupling. The input shaft of the gearbox is coaxially and fixedly connected to a drive wheel.

[0008] As a further improvement to this technical solution, the transmission assembly also includes a sealing cover fixedly installed on the outer wall of the roller frame. A rotating shaft is rotatably installed inside the sealing cover. The end of the rotating shaft away from the roller frame rotatably passes through the sealing cover and is coaxially fixedly connected to a driven wheel. A transmission belt drives the driven wheel and the driving wheel.

[0009] As a further improvement to this technical solution, a driving bevel gear is coaxially fixedly connected to the rotating shaft, and a driven bevel gear is coaxially fixedly connected to the axle of one of the synchronous pulleys through the mounting frame. The driven bevel gear meshes with the driving bevel gear.

[0010] As a further improvement to this technical solution, the cleaning component includes several rubber frames integrally formed on the outer side wall of the timing belt. A sponge is fixedly connected inside the rubber frame by Velcro. When the sponge rotates with the timing belt to below the timing belt, the lower side wall of the sponge slides into contact with the top of the adjusting roller.

[0011] As a further improvement to this technical solution, a limiting frame is fixedly installed inside the roller frame. The lower side wall of the limiting frame slides in contact with the bottom side inside the synchronous belt. Two stop bars are symmetrically fixedly connected to the lower side wall of the limiting frame. The sides of the two stop bars that are close to each other slide in contact with the two sides of the synchronous belt.

[0012] As a further improvement to this technical solution, the elastic adjustment mechanism includes four slide rods that are respectively vertically fixed at the four corners of the upper side wall of the roller frame. The upper end of each slide rod slides through the top of the assembly frame and is threaded with a nut.

[0013] As a further improvement to this technical solution, a return spring sleeved on the slide rod is provided between the bottom side of the assembly frame and the upper side wall of the roller frame. The return spring is used to push the roller frame to move vertically downward.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. The energy-saving belt conveyor roller support structure, when the belt drives the adjusting roller to rotate, the rotating adjusting roller drives the synchronous belt to move through the drive transmission component. At the same time, the limit frame constrains the movement trajectory of the synchronous belt, so that the sponge fixed on the synchronous belt can wipe the surface of the rotating adjusting roller with stable pressure. This design allows the sponge to move along the axis of the adjusting roller when it rotates, so that the sponge can wipe the surface of the adjusting roller. Through continuous wiping, the sponge can wipe the entire circumference of the adjusting roller, ensuring that there is not too much dust and impurities on the adjusting roller, thereby maintaining the efficient and stable operation of the belt drive system.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 and Figure 3 As shown, the purpose of this embodiment is to provide an energy-saving belt conveyor roller support structure, including an assembly frame 1. In use, the assembly frame 1 is vertically fixed on the conveyor bracket by bolts. Multiple assembly frames 1 are arranged in a horizontal array to form a stable support base. The top of the assembly frame 1 is fixedly installed with a roller bracket 11 for installing three rollers. When the three rollers are rotated and installed on the roller bracket 11, the three rollers are arranged in a U-shape with an outward opening. When the belt is installed on the rollers, the top side of the belt contacts the circumferential sidewalls of all rollers and passes through the bottom of the assembly frame 1, so that the belt forms a trough-shaped structure with a low middle and high sides under the constraint of the rollers, effectively preventing the conveyed material from slipping off from both sides.

[0035] To maintain the belt's continuous tension, a roller frame 2 is slidably mounted on the lower side of the mounting frame 1. An adjusting roller 3 is rotatably mounted on the roller frame 2. The belt passes under the adjusting roller 3. An elastic adjusting mechanism 4 is provided between the roller frame 2 and the mounting frame 1. The elastic adjusting mechanism 4 is used to push the roller frame 2 to move vertically downward, so that the bottom of the adjusting roller 3 is in close contact with the inner bottom side of the belt. This ensures sufficient friction between the belt and the roller and the adjusting roller 3. This design ensures that the roller connected to the external power source can efficiently drive the belt, reduce slippage, reduce energy loss, and allow the moving belt to drive the adjusting roller 3 to rotate through friction with it, reducing mutual wear between the adjusting roller 3 and the belt due to slippage.

[0036] The structure of the elastic adjustment mechanism 4 is described in detail below, with reference to... Figure 2 The elastic adjustment mechanism 4 includes four slide rods 41, which are respectively vertically fixed at the four corners of the upper side wall of the roller frame 2. The upper end of the slide rod 41 slides through the top of the assembly frame 1 and is threaded with a nut 42. The nut 42 is used to prevent the slide rod 41 from separating from the assembly frame 1, thus preventing the assembly frame 1 from becoming disconnected from the roller frame 2. A return spring 43 is provided inside the bottom side of the assembly frame 1 between the bottom side and the upper side wall of the roller frame 2, which is sleeved on the slide rod 41. The return spring 43 is used to push the roller frame 2 to move vertically downward. When the belt passes under the adjusting roller 3, the return spring 43 continuously applies a downward elastic force, causing the roller frame 2 to move downward. The roller frame 2 drives the adjusting roller 3 to apply downward pressure to the bottom side of the belt, while the belt also applies pressure to the adjusting roller 3. At this time, the return spring 43 is also compressed by the taut belt (the belt is taut when it is first installed). When the belt becomes loose due to long-term use, the pressure of the belt on the adjusting roller 3 decreases. At this time, the return spring 43 pushes the adjusting roller 3 to move downward (the return spring 43 is selected to be a spring that can push the belt to move), automatically compensating for the tension loss caused by the loose belt, so that the belt has a downward convex shape, thereby maintaining the belt's taut state and realizing the automatic tensioning of the belt.

[0037] To clean dust and impurities from the circumferential sidewall of adjusting roller 3, refer to... Figure 5 Mounting frames 5 are fixedly connected to both sides of the roller frame 2, and the mounting frames 5 are connected to the inside of the roller frame 2. A synchronous pulley 6 is rotatably mounted inside the mounting frame 5. The two synchronous pulleys 6 are connected by the same synchronous belt 7. A cleaning component 9 is provided on the outside of the synchronous belt 7. The cleaning component 9 is located above the adjusting roller 3. A transmission component 8 is provided between the adjusting roller 3 and one of the synchronous pulleys 6.

[0038] When the belt is running, it drives the adjusting roller 3 to rotate through friction. The adjusting roller 3 drives the corresponding synchronous pulley 6 to rotate through the transmission component 8. The rotating synchronous pulley 6 drives the synchronous belt 7 to move, which in turn drives the cleaning component 9 to move along the axis of the adjusting roller 3. When the cleaning component 9 comes into contact with the side wall of the adjusting roller 3, the cleaning component 9 wipes the surface of the adjusting roller 3 and cleans the circumferential side wall of the adjusting roller 3. As the synchronous belt 7 drives the cleaning component 9 to move continuously, coupled with the rotation of the adjusting roller 3, the cleaning component 9 cleans the dust from the circumferential side wall of the adjusting roller 3, preventing excessive impurities from adhering to the adjusting roller 3 and affecting the friction between the adjusting roller 3 and the belt, thus avoiding slippage between the adjusting roller 3 and the belt.

[0039] The structure of transmission component 8 is described in detail below, with reference to... Figure 4 and Figure 6 The transmission assembly 8 includes a gearbox 82 fixedly mounted on the outer wall of the roller frame 2. The gearbox 82 can be a planetary gearbox of model PG16. The input shaft of the gearbox 82 is coaxially fixedly connected to the adjusting roller 3 via a coupling. The input shaft of the gearbox 82 is coaxially fixedly connected to the driving wheel 83. The transmission assembly 8 also includes a sealing cover 81 fixedly mounted on the outer wall of the roller frame 2. A rotating shaft 84 is rotatably mounted inside the sealing cover 81. The end of the rotating shaft 84 away from the roller frame 2 rotatably passes through the sealing cover 81 and is coaxially fixedly connected to a driven wheel 88. A transmission belt 85 is drivingly connected between the driven wheel 88 and the driving wheel 83. A driving bevel gear 86 is coaxially fixedly connected to the rotating shaft 84. The axle of one of the synchronous pulleys 6 rotatably passes through the mounting frame 5 and is coaxially fixedly connected to a driven bevel gear 87. The driven bevel gear 87 meshes with the driving bevel gear 86.

[0040] When the adjusting roller 3 rotates, it drives the input shaft of the gearbox 82 to rotate. The output shaft of the gearbox 82 rotates at an increased speed, which drives the drive wheel 83 to rotate. The gearbox 82's speed change principle is existing technology, so it will not be described in detail here. The drive wheel 83 drives the driven wheel 88 to rotate through the transmission belt 85, which in turn drives the drive bevel gear 86 to rotate through the rotating shaft 84. This drives the driven bevel gear 87 to rotate through the corresponding synchronous pulley 6, which in turn drives the synchronous belt 7 to rotate. The synchronous belt 7 drives the cleaning component 9 to move, thus achieving the cleaning effect of the cleaning component 9.

[0041] The structure of cleaning component 9 is described in detail below, please refer to... Figure 7 and Figure 8The cleaning component 9 includes several rubber frames 91 integrally formed on the outer wall of the timing belt 7. The inside of the rubber frame 91 is fixedly connected to a sponge 92 by Velcro. The rubber frame 91 restricts the displacement of the sponge 92. When one of the sponges 92 rotates with the timing belt 7 into the inside of one of the mounting frames 5, it is convenient for the operator to tear the sponge 92 out of the inside of the rubber frame 91 and then stick a new sponge 92 into the inside of the rubber frame 91, so as to facilitate the replacement of the sponge 92.

[0042] When several sponge wipers 92 rotate with the synchronous belt 7 and slide into contact with the top of the adjusting roller 3, the moving sponge wipers 92 can wipe the side wall of the adjusting roller 3. At the same time, the rotating adjusting roller 3 will also have an arc-shaped displacement relationship with the sponge wipers 92, so that the wiping trajectory of the sponge wipers 92 on the adjusting roller 3 forms a spiral shape. As the cleaning component 9 moves continuously with the synchronous belt 7, several sponge wipers 92 wipe the surface of the adjusting roller 3, so that the sponge wipers 92 can wipe the arc-shaped surface of the adjusting roller 3 thoroughly, preventing dust from accumulating on the surface of the adjusting roller 3 and ensuring the friction between the adjusting roller 3 and the belt.

[0043] Meanwhile, a limiting frame 12 is fixedly installed inside the roller frame 2. The lower side wall of the limiting frame 12 slides in contact with the bottom side inside the synchronous belt 7. When the sponge wiper 92 contacts the top of the adjusting roller 3, the limiting frame 12 prevents the sponge wiper 92 from moving upward, so that the sponge wiper 92 has enough pressure to wipe the adjusting roller 3, ensuring its cleaning effect on the adjusting roller 3. In addition, two baffles 121 are symmetrically fixedly connected to the lower side wall of the limiting frame 12. The side of the two baffles 121 that is close to each other slides in contact with the two sides of the synchronous belt 7 respectively. The two baffles 121 restrict the synchronous belt 7 from shifting, so that the sponge wiper 92 can move stably along the axial direction of the adjusting roller 3, ensuring that the sponge wiper 92 can thoroughly clean the circumferential side wall of the adjusting roller 3.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
