Technical Field

[0001] This utility model relates to the field of idler roller technology, specifically to an idler roller and its support. Background Technology

[0002] The main function of the idler roller bracket is to provide stable support for the idler roller, ensuring its normal operation. Secondly, it can fix the position and angle of the idler roller to prevent it from moving or tilting. In existing technologies, the idler roller bracket and support are mostly fixedly welded together, making the angle between the idler rollers unadjustable. However, in different operating environments, operators often need to select bracket styles with different inclination angles, resulting in poor applicability of the device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an idler roller and its support, which has the advantages of being able to adjust the angle between multiple idler roller bodies according to different usage environments, and has high applicability. This solves the problem in existing technologies where different inclination bracket styles are required for different usage environments, resulting in poor applicability of the device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A roller and its support include a main body mechanism as the main body of the device. The main body mechanism includes a support a, two supports b, and a roller body. The bottom of the main body mechanism is provided with an adjustment mechanism for easy adjustment of the angle between adjacent roller bodies. The bottom of the main body mechanism is also provided with a balancing mechanism to facilitate stable transmission of the device. The adjustment mechanism includes fixed frames fixedly connected to both sides of the support a. A rotating shaft is rotatably connected inside each fixed frame. A rotating frame is fixedly connected to each of the two rotating shafts. A gear is rotatably connected to one side of each of the two fixed frames. A fixed plate is fixedly connected to one side of the support a. Electric telescopic rods are installed on both sides of the fixed plate. A connecting plate is fixedly connected to the movable end of each of the two electric telescopic rods. A locking block is fixedly connected to the opposite side of each of the two connecting plates. A synchronous pulley is fixedly connected to the other side of each of the two fixed frames. A synchronous belt is installed between the two synchronous pulleys. A rotating handle is fixedly connected to one side of one of the synchronous pulleys.

[0006] Preferably, the two ends of the rotating shaft pass through both sides of the fixed frame and are fixedly connected to the gear and the synchronous wheel, respectively, and the two rotating frames are respectively connected to the two brackets b.

[0007] Preferably, the balancing mechanism includes a base frame fixedly connected to the bottom of the support a, a through groove is provided on the bottom wall of the base frame, a screw is rotatably connected in the through groove, a sliding plate is threaded onto the screw, and a counterweight is installed on the sliding plate.

[0008] Preferably, the tube body and bearing housing of the idler roller are both made of polymer composite material, and a multi-stage sealing structure combining lip and labyrinth is adopted.

[0009] Preferably, each of the bracket a and the two brackets b has two connecting seats fixedly connected, and the multiple idler roller bodies are installed and connected to the multiple connecting seats.

[0010] Preferably, the two locking blocks can lock the two gears respectively, and a micro motor for driving the screw is installed on one side of the base frame.

[0011] By employing the above technical solution, this utility model provides an idler roller and its support, which has at least the following beneficial effects:

[0012] 1. This utility model enables the device to easily adjust the angle between multiple roller bodies by setting an adjustment mechanism. By rotating the handle, two synchronous pulleys rotate synchronously through the synchronous belt. Under the action of the rotating shaft, two gears rotate synchronously, thereby adjusting the included angle between the two supports b and the support a synchronously. When the angle is determined, two electric telescopic rods drive two connecting plates to move, so that two locking blocks fix the two gears, thereby fixing the angle and improving the applicability of the device.

[0013] 2. This utility model, by setting a balancing mechanism, enables the device to further enhance the stability of the support a. By driving the screw to rotate through a micro motor, the position of the slide plate is moved, so that the position of the counterweight can follow the slide plate. This allows the device to adaptively adjust the position of the counterweight according to the weight distribution of the object being transported on the roller body, ensuring the stability of the device during the transmission process.

[0021] 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.

[0022] In the prior art, the idler roller bracket and support are mostly fixedly welded, which makes it impossible to adjust the angle between the idlers. Therefore, workers need to select different bracket styles with different inclinations in different usage environments, resulting in poor applicability of the device. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing an idler roller and its bracket.

[0023] Example 1:

[0024] To facilitate the adjustment of the angle between the roller bodies 104, combined with Figures 1-4 As shown, a roller and its support are proposed. The main body 1 is set as the main body of the device. An adjustment mechanism 2 is set at the bottom of the main body 1. The adjustment mechanism 2 is used to easily adjust the angle between adjacent roller bodies 104. A balancing mechanism 3 is set at the bottom of the main body 1. The balancing mechanism 3 enables the device to transmit stably.

[0025] To adapt the idler roller bracket to different operating environments, an adjustment mechanism 2 is proposed. This mechanism comprises fixed brackets 201 connected to both sides of bracket a101. Each fixed bracket 201 has a rotating shaft rotatably connected to it, and a rotating frame 202 is fixedly connected to each of the two rotating shafts. A gear 203 is rotatably connected to one side of each of the two fixed brackets 201. A fixed plate 206 is fixedly connected to one side of bracket a101. Electric telescopic rods 207 are installed on both sides of the fixed plate 206. Connecting plates 204 are fixedly connected to the movable ends of both electric telescopic rods 207. Locking blocks 205 are fixedly connected to the opposite sides of the two connecting plates 204. Synchronous pulleys 208 are fixedly connected to the other sides of each of the two fixed brackets 201. A synchronous belt 209 is installed between the two synchronous pulleys 208. A handle 210 is fixedly connected to one side of one synchronous pulley 208. The two ends of the rotating shaft pass through the two fixed brackets 201 respectively. The side is fixedly connected to gear 203 and synchronous pulley 208. Two rotating frames 202 are respectively connected to two brackets b102. Two locking blocks 205 can lock the two gears 203 respectively. The rotating frame 202 can be easily adjusted and rotated through the fixed frame 201 and the rotating shaft. By rotating the handle 210, the two synchronous pulleys 208 rotate synchronously through the synchronous belt 209. Under the action of the rotating shaft, the two gears 203 rotate synchronously, thereby adjusting the included angle between the two brackets b102 and the bracket a101 synchronously. When the angle is determined, the position of the two electric telescopic rods 207 is fixed by the fixed plate 206. The two electric telescopic rods 207 drive the two connecting plates 204 to move, so that the two locking blocks 205 fix the two gears 203, thereby fixing the angle. There is no need to change the style of the idler roller bracket, which improves the applicability of the device.

[0026] Example 2:

[0027] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, the roller bracket and the support are mostly fixedly welded, so the angle between the rollers cannot be adjusted. However, in different usage environments, the staff usually need to select different bracket styles with different inclinations, resulting in poor applicability of the device. Furthermore, when the rollers are transporting objects, if the two rollers on the bracket b102 bear different weights, the transportation process of the objects is less stable.

[0028] To ensure the stability of objects during transportation, combined with Figure 1 and Figure 2 as well as Figure 4As shown, a balancing mechanism 3 is proposed. A base frame 301 is fixedly connected to the bottom of the support a101. A through groove 302 is provided on the bottom wall of the base frame 301. A screw 303 is rotatably connected in the through groove 302. A slide plate 304 is threadedly connected to the screw 303. A counterweight 305 is installed on the slide plate 304. A micro motor for driving the screw 303 is installed on one side of the base frame 301. The micro motor drives the screw 303 to rotate, thereby causing the slide plate 304 to move through the through groove 302. This allows the position of the counterweight 305 to move with the slide plate 304. The device can adaptively adjust the position of the counterweight 305 according to the weight distribution of the object being transported on the roller body 104, ensuring the stability of the device during the transport process.

[0029] To facilitate the transportation of objects, a main structure 1 is proposed, comprising a mounting bracket a101, two brackets b102, and a roller body 104. Each bracket a101 and each bracket b102 has two connecting seats 103 fixedly connected to it. Multiple roller bodies 104 are connected to multiple connecting seats 103. The roller body 104 employs a multi-stage sealing structure combining lip and labyrinth sealing, making it difficult for water and dust to penetrate. Under the same conditions, its lifespan is more than twice that of a standard metal roller, it resists UV aging for more than 8 years, and its weight is about 1 / 3 lighter than a comparable metal roller. The tube has no metal lining, making handling and installation convenient, greatly reducing labor intensity, shortening maintenance time, and improving production efficiency. The tube body and bearing housing are made of high-strength, wear-resistant, and corrosion-resistant polymer composite materials, so they are neither corrosive nor wear-resistant. In belt conveyors with belt buckle connections, the belt... The contact noise between the buckle and the tube is about 15 decibels lower than that between the belt buckle and the metal tube, making the working environment more environmentally friendly. Its surface hardness is slightly higher than that of the belt and it is not abrasive. When the idler is rotating, the tube is worn away from the belt in a short time, thus protecting the belt. Its rotating parts are lightweight and the moment of inertia is half that of a standard metal idler. It requires less driving force, reduces the motor starting current, and makes braking easier. It saves tens of thousands to hundreds of thousands of kWh of electricity per kilometer of belt conveyor per year. After the rotating parts fail, the idler shaft can be recycled and reused because there are no welds. Other parts can also be recycled and reused. It will not generate sparks from wear with the belt buckle during operation, and it will not generate high temperatures from friction with the belt under working conditions where the idler is not rotating due to deformation of the conveyor frame. It can be used between -50℃ and 70℃, which greatly improves the service life of the idler body 104.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
