Description

Technical Field

[0001] This utility model relates to the field of rubber rollers, and in particular to a rubber roller balance detection device. Background Technology

[0002] Rubber rollers are cylindrical key components made by vulcanizing and bonding metal (such as steel or aluminum) core shafts covered with an elastic rubber layer (natural rubber, nitrile rubber, silicone rubber, etc.). They are widely used in industrial production lines such as printing, papermaking, leather, plastics, and textiles. In order to eliminate mass imbalance during rotation and ensure the stability of equipment operation and product processing accuracy, rubber rollers must undergo dynamic balancing tests before leaving the factory, thereby reducing production safety risks. For dynamic balancing tests of some hard rubber rollers, a balancing machine is often used. Some balancing machines use a drive belt to drive the roller to rotate. That is, the drive belt covers the outer surface of the roller and forms a tight contact to achieve power transmission. However, during the roller loading before testing and the roller unloading after testing, the drive belt needs to be removed separately to avoid it being fitted on the roller surface and hindering the loading and unloading operation. Regarding the aforementioned technologies, the inventors have discovered the following problems: First, the process of "disassembling the drive belt, hoisting the roller, and reinstalling the drive belt" must be repeated for each roller being inspected, which not only increases operational redundancy and reduces work efficiency, but also significantly extends the inspection cycle of a single roller; Second, the drive belt has elastic tension after being tensioned by the tensioning mechanism, and during disassembly, it is prone to sudden rebound due to the release of tension, which may cause the operator's hand to be pinched by the belt or tensioning components, posing a safety hazard. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a rubber roller balance testing device that eliminates the need to repeatedly perform the processes of disassembling the drive belt, hoisting the roller, and reinstalling the drive belt, thereby improving work efficiency and reducing the testing cycle of a single roller; at the same time, it reduces the safety hazards for workers.

[0004] To solve the above-mentioned technical problems, the present invention provides a rubber roller balancing detection device, comprising: a base and a balancing machine body connected to one side thereof. The top of the base is symmetrically provided with support assemblies, and a drive mechanism for driving the rubber roller to rotate is provided between the support assemblies. Rolling support seats are respectively installed on opposite sides of the support assemblies. The device also includes a linear guide mechanism. Both the support assemblies and the drive mechanism are slidably mounted on the base via the linear guide mechanism, enabling position adjustment along the length of the base. The drive mechanism includes a mounting frame and arc-shaped arms hinged to its top two sides. Several guide wheels are respectively installed on one side of each arc-shaped arm, and a mounting bracket is installed below one of the arc-shaped arms. The mounting frame includes a tensioning wheel assembly, and a drive wheel assembly mounted on the mounting frame is located below the other arc-shaped arm. Several guide wheels are provided between the tensioning wheel assembly and the drive wheel assembly. A connecting plate is provided on the top of the mounting frame, and guide wheels are provided at both ends of one side of the connecting plate. The axis of the guide wheels is coplanar with the axis of the guide wheels at the end of the arc-shaped arm. The mounting frame also includes an annular drive belt, which is sequentially wound around the guide wheels, guide wheels, guide wheels, tensioning wheel assembly, and drive wheel assembly to form a closed transmission structure. The outer side of the annular drive belt is in contact with the outer circular surface of the rubber roller. Telescopic rod assemblies are provided on both sides of the mounting frame, and the telescopic rod assemblies drive the corresponding arc-shaped arms to swing.

[0005] By adopting the above technical solution, the base provides stable support for the entire equipment, ensuring no shaking during the testing process. The balancing machine body, as the core testing unit, enables accurate acquisition and analysis of the imbalance of the rubber roller. The support base assembly is symmetrically arranged on the top of the base to provide positioning support for both ends of the rubber roller's spindle. The rolling support base is installed on the opposite side of the support base assembly to further assist in supporting the roller and reduce its frictional resistance during rotation. The two work together to achieve stable placement and smooth rotation of the roller, avoiding testing errors caused by unstable support. At the same time, it provides stable conditions for the subsequent drive mechanism and roller's contact transmission. Both the support base assembly and the drive mechanism are slidably set on the base through a linear guide mechanism, and their positions can be flexibly adjusted along the length of the base to adapt to rubber rollers of different lengths. Guide wheel one, guide wheel two, guide wheel three, tension wheel assembly, and drive wheel assembly work together. The same mechanism guides the annular drive belt to form a closed and stable transmission path, preventing the drive belt from shifting or falling off during movement. Furthermore, the tensioning wheel assembly adjusts the tension of the annular drive belt, ensuring close contact between the drive belt and the outer surface of the roller and the drive wheel assembly. The drive wheel assembly then rotates to drive the annular drive belt, achieving the roller rotation required for balanced testing. The telescopic rod assembly extends and retracts, driving the two arc-shaped arms to swing around the hinge point, thereby controlling the position of the guide wheel at the top of the arc-shaped arm. This switches between the contact and separation states of the annular drive belt and the outer surface of the rubber roller, solving the problem of repeated disassembly of the drive belt in traditional equipment. Before testing, the telescopic rod assembly extends to push the arc-shaped arms to swing, causing the drive belt to contact the roller. After testing, the telescopic rod retracts, causing the arc-shaped arms to reset, and the drive belt automatically detaches from the roller, allowing for direct roller hoisting without manual disassembly of the drive belt.

[0006] In a preferred embodiment, the present invention can be further configured as follows: the support assembly includes a movable seat and a U-shaped plate connected to one of its top sides, a support plate is connected to the other top side of the movable seat, a horizontal plate is connected to the same side of the U-shaped plate and the support plate, a roller is installed on the horizontal plate, a U-shaped protective frame is installed on the U-shaped plate by means of a pin, a laser displacement sensor is installed on one side of the closed end of the U-shaped protective frame, and a vibration sensing component is installed on the other side; The vibration sensing component includes a U-shaped cover, an L-shaped guide block slidably connected inside the U-shaped cover, a sensing wheel installed at the bottom end of the L-shaped guide block, a vibration sensor connected to the sensing wheel installed at one bottom side of the L-shaped guide block, a limit groove formed on the L-shaped guide block, a limit rod passing through the U-shaped cover, and one end of the limit rod located in the limit groove. One end of the opening of the U-shaped protective frame is provided with an integrally formed wedge-shaped positioning block, and a positioning opening is provided on the wedge-shaped positioning block. One side of the support plate is provided with an integrally formed positioning plate. A positioning groove matching the wedge-shaped positioning block is provided between the support plate and the positioning plate. A limit handle is threadedly connected to the positioning plate, and one end of the limit handle is located in the positioning opening.

[0007] By adopting the above technical solution, the roller contacts the outer circular surface of the rubber roller end, and the auxiliary rolling support seat realizes the rotational guidance of the roller. During the detection process, the U-shaped protective frame is hinged to the U-shaped plate by a pin and can be rotated around the pin to realize opening and closing. The laser displacement sensor is installed on one side of the closed end of the protective frame. Using a non-contact measurement method, it is aligned with the outer circular surface of the rubber roller and collects the radial runout data of the roller during rotation in real time. It is converted into an electrical signal and fed back to the main body of the balancing machine. In addition, the L-shaped guide block is slidably connected to the U-shaped cover, and the sensing wheel is installed at its bottom end and in close contact with the outer circular surface of the roller. When the roller rotates, it drives the sensing wheel to rotate synchronously and transmits the vibration to the vibration sensor. The limiting groove and the limiting rod cooperate to limit the sliding trajectory of the L-shaped guide block, ensuring that the sensing wheel is always in contact with the roller surface and preventing it from detaching due to vibration. The system uses a combination of mechanical contact and vibration sensing to accurately collect vibration frequency and amplitude data during roller rotation. This provides crucial information for analyzing the location and magnitude of imbalance in the balancing machine, preventing data distortion due to poor contact and improving the equipment's reliability. Furthermore, the wedge-shaped positioning block at the open end of the U-shaped protective frame matches the positioning groove on the support plate. When the protective frame is closed, the wedge-shaped positioning block inserts into the positioning groove for initial positioning. The positioning plate and support plate are integrally formed, and the limit handle is threaded onto the positioning plate. After tightening, one end of the handle is embedded in the positioning port of the wedge-shaped positioning block, locking the protective frame in place. This prevents the protective frame from loosening due to equipment vibration during testing. Disassembly is simple; just unscrew the limit handle in the opposite direction to open the protective frame. This convenient operation balances structural stability with efficient testing procedures.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the linear guide mechanism includes mounting plates respectively mounted on the support base assembly and the drive mechanism, a servo motor connected to the mounting plate, a drive gear connected to the output shaft of the servo motor, and a rack connected to the base, the drive gear meshing with the rack, sliding grooves respectively opened on the top two sides of the base, and sliders slidably connected to the sliding grooves respectively installed on the bottom two sides of the support base assembly and the drive mechanism.

[0009] By adopting the above technical solution, the servo motor provides a controllable power source for position adjustment, and achieves precise control of speed and direction according to the control signal, and drives the drive gear to rotate. Since the rack is fixed on the base and the two are meshed, it can provide precise power for the linear movement of the support assembly and the drive mechanism on the base. In addition, the sliding grooves symmetrically opened on both sides of the top of the base form a sliding fit with the sliders installed on both sides of the bottom of the support assembly and the drive mechanism. The sliders are embedded in the sliding grooves and can slide along the length of the groove, which forcibly limits the movement trajectory of the support assembly and the drive mechanism, effectively ensuring that the support assembly and the drive mechanism only move along the length of the base, and avoiding lateral offset or torsion during the adjustment process.

[0010] In a preferred embodiment, the present invention can be further configured such that: the telescopic rod assembly includes hinge seats respectively mounted on the side wall of the arc-shaped arm and on the side of the mounting frame; the hinge seats on the mounting frame are connected to an electric push rod via a pin; one end of the electric push rod is connected to a hinge joint; and the hinge joint is connected to the corresponding hinge seat via a pin.

[0011] The above-mentioned technical solution features connection and adaptation characteristics: the hinge seats are respectively installed on the side wall of the arc-shaped arm and the side of the mounting frame, serving as the connection fulcrum between the telescopic rod assembly and the arc-shaped arm and mounting frame, and achieving rotatable connection through pins. The hinge seats, electric push rods, and hinge joints cooperate to construct a stable and flexible power transmission link. When it is necessary to fit the drive belt, the electric push rod extends, pushing the arc-shaped arm to swing upward around the hinge point of the mounting frame through the hinge joint, driving the top guide wheel to move synchronously, so that the annular drive belt fits tightly against the outer surface of the roller; after the test is completed, the electric push rod retracts, pulling the arc-shaped arm downward to reset, and the drive belt automatically disengages from the roller, which not only solves the cumbersome disassembly of the traditional drive belt, but also reduces safety hazards.

[0012] In a preferred embodiment, the present invention can be further configured such that: the drive wheel assembly includes a drive motor mounted on a mounting bracket, the output shaft of the drive motor is connected to a belt drive wheel, and the belt drive wheel is in rolling contact with an annular drive belt.

[0013] By adopting the above technical solution, the belt drive wheel rotates synchronously with the motor, and its outer surface rolls in contact with the annular drive belt. The rotational power of the motor is transmitted to the annular drive belt through friction. When the equipment starts testing, the drive motor rotates at a preset speed, which drives the belt drive wheel to rotate synchronously. The belt drive wheel drives the annular drive belt to circulate along the trajectory defined by the guide wheel through friction, and finally drives the rubber roller that is in contact with it to rotate.

[0014] In a preferred embodiment, the present invention can be further configured such that: the tensioning wheel assembly includes a side plate, an electric cylinder is mounted on the side plate, the extended end of the electric cylinder is connected to a U-shaped seat, a tensioning pulley is mounted inside the U-shaped seat, and the tensioning pulley is in rolling contact with the annular drive belt.

[0015] By adopting the above technical solution, the electric cylinder drives the U-shaped seat and tension pulley to move through the linear telescopic motion of its extended end, thereby adjusting the tension of the annular drive belt. Compared with the traditional manually adjusted tensioning mechanism, the automatic adjustment of the electric cylinder not only improves operating efficiency but also compensates for the elastic deformation of the drive belt in real time during long-term use, maintaining stable tension and ensuring the continuous and reliable operation of the transmission system. The U-shaped seat connects the extended end of the electric cylinder to the tension pulley, and the tension pulley is rotatably mounted in the U-groove through a pin, forming a power system of "electric cylinder, U-shaped seat, and tension pulley". The transmission link ensures coaxiality during rotation and prevents pulley misalignment and drive belt deviation caused by unilateral force. During operation, the electric cylinder pushes the U-shaped seat and tension pulley to move according to preset parameters, applying stable pressure to the annular drive belt. This ensures that the drive belt is tightly fitted with the belt drive pulley and guide pulleys of the drive wheel assembly. During the testing process, the electric cylinder can monitor the tension of the drive belt in real time and compensate for elastic deformation through slight expansion and contraction to maintain constant tension. This prevents damage to the drive belt due to sudden tension changes when switching states, further improving the safety and service life of the transmission system.

[0016] In a preferred embodiment, the present invention can be further configured as follows: the rolling support includes a crossbar and a movable sleeve fitted on its surface, a vertical rod is mounted on the top of the movable sleeve, a side rod is rotatably connected to the vertical rod, a rotating bearing is mounted on one end of the side rod, the rotating bearing is in rolling contact with the end of the rubber roller, and locking handles are threadedly connected to the movable sleeve and the vertical rod respectively.

[0017] By adopting the above technical solution, the rolling support seat adjusts the position of the crossbar and movable sleeve, adapts the angle of the upright and side rods, and provides rolling support for the rotating bearing and locking fixation with the locking handle. When the rubber roller is hoisted to the inspection station, the position of the movable sleeve and the angle of the side rod are adjusted to make the rotating bearing fit tightly against the end of the roller and lock it. When the roller rotates for inspection, the rotating bearing rolls synchronously with the roller, which provides stable support and reduces friction interference.

[0018] In summary, this utility model includes at least one of the following beneficial technical effects of a rubber roller balance detection device: The arc-shaped arm is driven to swing by the telescopic rod assembly, realizing the automatic bonding and separation of the ring drive belt and the roller. This eliminates the repetitive processes of traditional drive belt disassembly, roller hoisting, and drive belt installation. In addition, the electric push rod extends before inspection to bond the drive belt, and retracts after inspection to separate it, eliminating the need for manual disassembly. This improves inspection efficiency and reduces safety hazards.

[0019] The drive motor precisely controls the speed and torque, and works in conjunction with the belt drive pulley to drive the ring drive belt to run stably, so that the rubber roller moves at a constant speed, avoiding the impact of speed fluctuations on the test results. During the rotation, the electric cylinder of the tensioning pulley assembly precisely adjusts the position of the tensioning pulley to ensure that the ring drive belt is always in a proper tension state, reducing transmission errors.

The hinge joint 493 is connected to the corresponding hinge seat 491 via a pin.

[0025] The base 1 provides stable support for the entire equipment, ensuring no shaking during the testing process. The balancing machine body 2 serves as the core testing unit, enabling accurate acquisition and analysis of the imbalance of the rubber roller. The support seat assembly 30 is symmetrically arranged on the top of the base 1 to provide positioning support for both ends of the rubber roller's spindle. The rolling support seat 50 is installed on the opposite side of the support seat assembly 30 to further assist in the support of the roller and reduce its frictional resistance during rotation. The two work together to achieve stable placement and smooth rotation of the roller, avoiding testing errors caused by unstable support.

Both the support seat assembly 30 and the drive mechanism 40 are slidably set on the base 1 through the linear guide mechanism 60, and their positions can be flexibly adjusted along the length of the base 1 to adapt to rubber rollers of different lengths. The guide wheel 1 43, guide wheel 2 46, guide wheel 3 48, tension wheel assembly 44, and drive wheel assembly 45 work together to guide the annular drive belt 4a to form a closed and stable transmission path, avoiding the annular drive belt 4a from moving... In case of deviation or detachment during movement, the tensioning wheel assembly 44 adjusts the tension of the annular drive belt 4a to ensure close contact between the drive belt and the outer surface of the roller and the drive wheel assembly 45. The drive wheel assembly 45 then rotates to drive the annular drive belt 4a, achieving the rotation of the roller required for balance detection. The extension and retraction of the electric push rod 492 drives the arc-shaped arm 42 to swing, achieving the engagement and disengagement of the annular drive belt 4a from the roller, completely replacing the tedious traditional manual disassembly of the drive belt and significantly improving work efficiency. Specifically, through the electric... The extension and retraction of the push rod 492 drives the two arc-shaped arms 42 to swing around the hinge point, thereby controlling the position of the guide wheel 43 at the top of the arc-shaped arm 42. This achieves the switching between the contact and separation states of the annular drive belt 4a and the outer surface of the rubber roller. Before the test, the electric push rod 492 extends to push the arc-shaped arm 42 to swing, so that the annular drive belt 4a is in contact with the roller. After the test is completed, the electric push rod 492 retracts to drive the arc-shaped arm 42 to reset, and the annular drive belt 4a is separated from the roller. The roller can be directly hoisted without the need for manual disassembly of the annular drive belt 4a.

[0026] The support assembly 30 includes a movable base 31 and a U-shaped plate 32 connected to one of its top sides. A support plate 33 is connected to the other side of the top of the movable base 31. A horizontal plate 34 is connected to the same side of the U-shaped plate 32 and the support plate 33. Rollers 35 are mounted on the horizontal plate 34. A U-shaped protective frame 36 is mounted on the U-shaped plate 32 via a pin. A laser displacement sensor 37 is mounted on one side of the closed end of the U-shaped protective frame 36, and a vibration sensing assembly 38 is mounted on the other side. The vibration sensing assembly 38 includes a U-shaped cover 381. An L-shaped guide block 382 is slidably connected inside the U-shaped cover 381. A sensing wheel 383 is mounted at the bottom end of the L-shaped guide block 382. A vibration sensor 384 connected to the sensing wheel 383 is installed on one side of the bottom of 82. A limit groove 385 is opened on the L-shaped guide block 382. A limit rod 386 is passed through the U-shaped cover 381. One end of the limit rod 386 is located in the limit groove 385.

[0027] Laser displacement sensor 37 and vibration sensor 384 are electrically connected to the balancing machine body 2. Roller 35 contacts the outer surface of the rubber roller end. Auxiliary rolling support 50 guides the roller rotation. During the detection process, U-shaped protective frame 36 is hinged to U-shaped plate 32 by a pin and can be rotated around the pin to open and close. Laser displacement sensor 37 is installed on one side of the closed end of U-shaped protective frame 36. Using a non-contact measurement method, it is aligned with the outer surface of the rubber roller and collects the radial runout data during the roller rotation process in real time, converting it into an electrical signal and feeding it back to the balancing machine body 2. In addition, L-shaped guide block 382 is slidably connected to U-shaped cover 381. Sensing wheel 383 is installed at its bottom end and is in close contact with the outer surface of the roller. When the roller rotates, it drives the sensing wheel 383 to rotate synchronously, transmitting the vibration to vibration sensor 384. Limiting groove 385 cooperates with limiting rod 386 to limit the sliding trajectory of L-shaped guide block 382, ​​ensuring that sensing wheel 383 is always in contact with the roller surface. The surface is closely fitted to prevent contact loss due to vibration. Through mechanical contact and vibration sensing, the vibration frequency and amplitude data of the rotating roller are accurately collected. This provides the core basis for the analysis of the position and magnitude of the imbalance in the main body 2 of the balancing machine, avoiding data distortion due to poor contact and improving the reliability of the equipment. On the other hand, the wedge-shaped positioning block 39 at the open end of the U-shaped protective frame 36 matches the positioning groove 3c on the support plate 33. The U-shaped protective frame 36 is initially positioned by inserting the wedge-shaped positioning block 39 into the positioning groove 3c. The positioning plate 3b and the support plate 33 are integrally formed. The limit handle 3d is threaded to the positioning plate 3b, and after tightening, one end of it is embedded in the positioning port 3a of the wedge-shaped positioning block 39 to lock and fix the U-shaped protective frame 36. This prevents the U-shaped protective frame 36 from loosening due to equipment vibration during the testing process. Moreover, the U-shaped protective frame 36 can be opened by simply unscrewing the limit handle 3d in the opposite direction. The operation is convenient and takes into account both structural stability and the efficiency of the testing process.

Slide grooves 65 are respectively opened on the top two sides of the base 1. Slider blocks 66 are respectively installed on the bottom two sides of the support assembly 30 and the drive mechanism 40 and are slidably connected to the slide grooves 65.

[0029] The servo motor 62 drives the gear 63 and rack 64 to mesh and transmit the rotational motion into linear motion, realizing precise adjustment of the spacing of the support assembly 30 and the position of the drive mechanism 40. The slide 65 and the slider 66 cooperate to provide stable guidance for the motion, avoiding lateral offset or torsion during the adjustment process, and ensuring the coaxiality of the roller support and the accuracy of the drive fit.

[0030] The drive wheel assembly 45 includes a drive motor 451 mounted on a mounting bracket 41. The output shaft of the drive motor 451 is connected to a belt drive wheel 452, which is in rolling contact with the annular drive belt 4a. The tension wheel assembly 44 includes a side plate 441, on which an electric cylinder 442 is mounted. The extended end of the electric cylinder 442 is connected to a U-shaped seat 443, and a tension pulley 444 is installed inside the U-shaped seat 443. The tension pulley 444 is in rolling contact with the annular drive belt 4a.

[0031] The drive motor 451 transmits power to the annular drive belt 4a via the belt drive pulley 452. The drive motor, in conjunction with the guide pulley 43, guide pulley 46, guide pulley 48, and tension pulley 444, drives the rubber roller to be tested to rotate. Furthermore, during operation, the electric cylinder 442 moves the U-shaped seat 443 and the tension pulley 444 according to preset parameters, applying stable pressure to the annular drive belt 4a. This ensures that the annular drive belt 4a is tightly fitted with the belt drive pulley 452 and each guide pulley. During the testing process, the electric cylinder 442 can monitor the tension of the annular drive belt 4a in real time, compensating for elastic deformation with slight expansion and contraction to maintain constant tension and prevent damage to the annular drive belt 4a due to sudden tension changes during state switching.

[0033] The rolling support seat 50 is positioned by the crossbar 51 and the movable sleeve 52, and the angles of the upright 53 and the side rod 54 are adapted. The rolling support of the rotating bearing 55 and the locking handle 56 are used for locking and fixing. After the rubber roller is hoisted to the inspection station, the position of the movable sleeve 52 and the angle of the side rod 54 are adjusted to make the rotating bearing 55 fit tightly with the end of the roller and lock it. When the roller rotates for inspection, the rotating bearing 55 rolls synchronously with the roller, which not only provides stable support but also reduces friction interference. On the other hand, other sensors can also be installed on the rotating bearing 55 to further improve the detection accuracy of the roller dynamic balance.

[0034] The implementation principle of this embodiment is as follows: During use, the roller to be tested is hoisted onto the support assembly 30 using specialized equipment such as a crane. Before this, the servo motor 62 drives the gear 63 and rack 64 to mesh and transmit power, causing the movable seat 31 of the support assembly 30 to slide along the slide groove 65 of the base 1 until the distance between the two support assemblies 30 matches the length of the roller. At the same time, the U-shaped protective frame 36 and the arc-shaped arm 42 are in the open state. Subsequently, the rolling support 50 is manually fine-tuned: the locking handle 56 is released, and the movable sleeve 52 is slid along the crossbar 51 to adjust the lateral position. The moving side rod 54 is adapted to the roller end angle to align the rotating bearing 55 with the preset contact point at the roller end. The locking handle 56 is tightened to lock the position. After confirming that the roller is placed stably, the U-shaped protective frame 36 is flipped over, and the wedge-shaped positioning block 39 is inserted into the positioning groove 3c between the support plate 33 and the positioning plate 3b. The limit handle 3d is tightened so that one end of the limit handle 3d is embedded in the positioning port 3a, locking the U-shaped protective frame 36. Then, the electric push rod 492 extends and pushes the arc arm 42 to swing around the hinge point of the mounting frame 41 through the hinge joint 493, so that the annular drive belt 4a is in contact with the outside of the roller. The circular surfaces are tightly fitted together, and then the drive motor 451 drives the belt drive pulley 452 to rotate. Through the annular drive belt 4a, and in coordination with the guide pulley 43, guide pulley 46, guide pulley 48, and tension pulley 444, the rubber roller to be detected is rotated. At this time, the laser displacement sensor 37 is aligned with the outer circular surface of the roller. The sensing wheel 383 of the vibration sensing component 38 is in contact with the outer circular surface of the roller under the gravity of the L-shaped guide block 382. The laser displacement sensor 37 collects the radial runout data of the roller in real time, and the vibration sensor 384 is connected to the outer circular surface of the roller through the sensing wheel 383. 3. The frequency and amplitude of the roller rotation vibration are captured and transmitted synchronously to the balancing machine body 2. The balancing machine body 2 analyzes and calculates the roller imbalance and phase position. After the test is completed, the drive motor 451 stops, the electric push rod 492 retracts, driving the arc arm 42 to reset, and the annular drive belt 4a separates from the outer surface of the roller. The electric cylinder 442 of the tension wheel assembly 44 retracts, releasing the tension of the annular drive belt 4a. Then, the limit handle 3d is loosened, the U-shaped protective frame 36 is opened, and the tested roller is lifted off the work station by the hoisting equipment, thus completing the test operation.
