Description

Technical Field

[0001] This invention relates to the field of metal surface treatment, and in particular to a transverse adaptive roller seat and roller changing car. Background Technology

[0002] After steel plates are manufactured, they are made into corresponding parts according to different usage requirements. However, before the steel plates are put into the manufacturing process, preparation time is always allowed. During this time, the steel plates will react with moisture and chemicals in the air, causing the surface material to peel off or rust. The earliest method to remove the rust layer was acid pickling, but this method is costly and polluting. Therefore, grinding equipment that removes rust by brushing the surface of the steel plate has emerged. This equipment uses brush rollers to physically grind the surface of the steel plate, improving the rust removal efficiency and reducing pollution, thus gaining acceptance. However, this equipment requires the brush rollers to contact the surface of the steel plate during grinding. With prolonged use, the polishing effect will decrease. Therefore, the brush roller needs to be placed on the roller changing trolley before being replaced with a new roller. Due to the large mass of the brush roller, it must be aligned with the guide mechanism between the clamping mechanism and the support device when it falls onto the support device to ensure that the support device receives the roller in place and avoid equipment damage caused by the brush roller deviating from the support device. However, during the alignment process, collisions between components will inevitably occur. When components collide, they will impact the support device in the vertical direction and also cause the support device to have a tendency to move horizontally. This tendency to move horizontally is equivalent to applying a lateral force to the support device during the guiding process, which causes many problems for the roller changing device during the roller changing process.

[0003] Firstly, vertical impacts will affect the structural strength and lifespan of the support device. Secondly, when a lateral force is applied to the support device, it will exert a lateral pulling effect, which is equivalent to a torsional effect on the bottom of the support device, causing it to tend to tip over. When the force of the guide mechanism is large, this torsional effect will cause the bottom of the support device to tilt. At this time, the bottom of the support device is not in a horizontal state. When the clamping roller mechanism places the brush roller on the support device, it may cause the brush roller and the support device to tip over simultaneously, creating a safety hazard during the roller changing process. Even if the brush roller is barely placed on the support device, the tilted side of the support device will still collide under the weight of the brush roller. After long-term use, the structural strength and lifespan of the entire support device will be affected. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a transversely adaptive roller seat. By setting a longitudinal elastic mechanism and a transverse elastic mechanism between the receiving mechanism and the fixing mechanism, the longitudinal elastic mechanism first allows the receiving mechanism to elastically float up and down, reducing the impact on the roller seat in the vertical direction; then, the transverse elastic mechanism allows the receiving mechanism to elastically displace in the transverse direction, thereby enabling the roller seat to adapt to the transverse force on the receiving mechanism. This not only improves the service life of the roller seat but also prevents the roller seat from tipping over.

[0005] Furthermore, a roller changing vehicle is provided, which arranges two transverse adaptive roller seats side by side, and places a new roller on the rear transverse adaptive roller seat, so that the roller clamping mechanism can cooperate with the guiding mechanism of the two front and rear transverse adaptive roller seats respectively, and quickly completes the replacement of the brush roller while ensuring the stability of the roller seats.

[0006] The technical solution of this invention is implemented as follows:

[0007] A lateral adaptive roller holder includes a fixing mechanism and a receiving mechanism. The receiving mechanism is positioned above the fixing mechanism and can cooperate with a vertically movable clamping roller mechanism to complete roller receiving. A lateral elastic mechanism and a longitudinal elastic mechanism are provided between the upper end of the fixing mechanism and the lower end of the receiving mechanism. The longitudinal elastic mechanism provides longitudinal elastic support to the receiving mechanism. A guiding mechanism is provided on the receiving mechanism. The lateral elastic mechanism can cause the receiving mechanism to generate a lateral elastic displacement in the corresponding direction when the guiding mechanism cooperates with the clamping roller mechanism, thereby allowing the roller holder to adapt to the lateral force generated when the guiding mechanism and the clamping roller mechanism cooperate.

[0008] Preferably, the lateral elastic mechanism includes two symmetrical lateral elastic components. Each lateral elastic component includes a cylindrical body and a lateral elastic wheel. The cylindrical body is positioned above the fixing mechanism, and the lateral elastic wheel is connected to the lower end of the receiving mechanism. On the outer wall of the cylindrical body in the front-back, left-right, and right-side directions, the left or right side wall is unoccupied, while on the other three sides of the cylindrical body, corresponding lateral elastic wheels abut against it. When the guiding mechanism cooperates with the clamping roller mechanism, the receiving mechanism is subjected to a lateral force, causing the corresponding lateral elastic wheel to abut against the cylindrical body and undergo elastic deformation, thereby generating a lateral elastic displacement in the corresponding direction. The lateral elastic components provide the receiving mechanism with a spatial margin for lateral elastic displacement. After the receiving mechanism is subjected to a lateral force, the lateral elastic components absorb the lateral force and form a lateral elastic support for the receiving mechanism, allowing the receiving mechanism to return to its lateral position.

[0009] Preferably, the upper and lower ends of the longitudinal elastic mechanism are hinged to the lower part of the receiving mechanism and the upper part of the fixed mechanism, respectively. When the guide mechanism cooperates with the clamping roller mechanism, the upper and lower ends of the longitudinal elastic mechanism rotate, causing the receiving mechanism to deflect longitudinally. This causes the transverse elastic wheel in the corresponding direction to abut against the cylindrical body and undergo elastic deformation, thereby forming a deflection elastic support force on the receiving mechanism. The hinged design of the longitudinal elastic mechanism allows the receiving mechanism to move laterally or deflect vertically naturally when subjected to transverse forces, avoiding deformation and breakage at the connection between the longitudinal elastic mechanism and the receiving mechanism. After deflection, the receiving mechanism can be restored to a horizontal state again using the elastic support force of the transverse elastic component, thereby preventing the receiving mechanism from tipping over on the fixed mechanism.

[0010] Preferably, the guide assembly includes left and right guide assemblies and front and rear guide assemblies. The left and right guide assemblies and the front and rear guide assemblies are symmetrically arranged between the clamping roller mechanism and the receiving mechanism. The left and right guide assemblies and the front and rear guide assemblies all use a component contact surface pressing cooperation method to make the receiving mechanism produce lateral elastic displacement. The component contact surface pressing guide cooperation method can make the clamping roller mechanism and the receiving mechanism gradually align, avoiding collision and scratching of components during the guide cooperation.

[0011] Preferably, the left and right guide components include a guide support with a Y-shaped groove disposed on the receiving mechanism and a circumferentially rotatable guide post disposed on the clamping roller mechanism. The opening of the Y-shaped groove is connected to the top of the guide support, thereby forming two symmetrical inclined surfaces on the guide support. The guide post contacts and rotates with the inclined surfaces, thereby guiding the guide post to the lower part of the Y-shaped groove and causing the transverse elastic wheel at the lower end of the receiving mechanism to undergo elastic deformation in the left and right directions, so that the receiving mechanism produces elastic displacement in the left and right directions; thereby aligning the receiving mechanism and the clamping roller mechanism in the left and right directions.

[0012] Preferably, the front and rear guide assembly includes an elastic swing wheel and a guide plate. The elastic swing wheel is mounted on the receiving mechanism and can elastically deflect back and forth relative to the receiving mechanism. The guide plate is mounted on the clamping roller mechanism and has a guide slope. The guide slope, through pressing and engaging with the elastic swing wheel, causes the elastic swing wheel to rotate and elastically deflect, thereby causing the transverse elastic wheel at the lower end of the receiving mechanism to elastically deform, thus causing the receiving mechanism to produce elastic displacement in the front and rear direction. The elastic deflection function of the elastic swing wheel can cause the transverse force generated by the receiving mechanism to align the receiving mechanism and the clamping roller mechanism in the front and rear direction.

[0013] Preferably, the guide slope of the guide plate extends upward and intersects with the vertical plane of the guide plate. The lower end of the vertical plane contracts inward and downward, thus forming a supporting slope on the guide plate. While the elastic swing wheel in the front-back direction cooperates with the guide slope for guidance, the guide column in the left-right direction presses against the slope on the Y-shaped slot, causing the receiving mechanism to generate elastic displacement in the left-right direction. At this time, the elastic swing wheel simultaneously contacts the vertical plane and the supporting slope and stops rotating. Under the drive of the receiving mechanism, it slides relative to the guide plate in the left-right direction. The vertical plane and the supporting slope provide two support points for the elastic swing wheel, so that after the elastic swing wheel stops rotating, it is only subjected to the frictional force of sliding in the left-right direction, avoiding damage to the elastic swing wheel structure caused by the oblique resultant force.

[0014] Preferably, a leveling mechanism is symmetrically provided at four diagonal positions between the clamping roller mechanism and the receiving mechanism. The leveling mechanism includes a top block and a top column respectively provided on the clamping roller mechanism and the receiving mechanism. When the receiving mechanism deflects horizontally, the clamping roller mechanism continues to descend until the top block in the leveling mechanism and the top column at the corresponding position abut against each other, thereby restoring the receiving mechanism to a horizontal state. Through the leveling process at the four diagonal positions, the receiving mechanism can further eliminate the longitudinal or lateral offset, and return the receiving mechanism to its initial horizontal state.

[0015] Preferably, the longitudinal elastic mechanism is symmetrically arranged between the upper end of the fixing mechanism and the lower end of the receiving mechanism. The elastic mechanism is in a compressed state under the action of the tension member, thereby generating an upward pre-tightening support elastic force on the receiving mechanism, so that the receiving mechanism remains in a horizontal state. Under the support of the pre-tightening support elastic force, the receiving mechanism can stably maintain a horizontal state and is not easily disturbed and will not sway up and down.

[0016] Preferably, the tensioning element is a chain located beside the longitudinal elastic mechanism. The two ends of the chain are connected to the receiving mechanism and the fixing mechanism respectively and are always kept taut, thereby keeping the longitudinal elastic mechanism in a compressed state. The chain can keep the longitudinal elastic mechanism in a compressed state, thereby providing a stable pre-tightening support force for the receiving mechanism.

[0017] Furthermore, a roller changing car is provided, including two transverse adaptive roller seats arranged side by side in a front-to-back direction. The receiving mechanism of the front roller seat remains unloaded, while the receiving mechanism of the rear roller seat is equipped with a new roller.

[0018] Preferably, the fixing mechanisms of the two lateral adaptive roller seats are connected to form a chassis, which can drive the lateral adaptive roller seats to move in the front-to-back direction. After the clamping roller mechanism cooperates with the guide mechanism on the front lateral adaptive roller seat to complete the old roller receiving, the chassis moves forward, aligning the rear lateral adaptive roller seat with the clamping roller mechanism, and then the clamping roller mechanism cooperates with the guide mechanism on the rear lateral adaptive roller seat again to complete the clamping of the new roller. This avoids the influence of lateral force on the roller seats during the roller changing process and also improves the efficiency of roller changing.

[0019] The principle of the present invention, which adopts the above technical solution, is as follows:

[0020] The present invention first provides a transversely adaptive roller seat, which sets a longitudinal elastic mechanism and a transverse elastic mechanism between the receiving mechanism and the fixing mechanism. The longitudinal elastic mechanism is first used to make the receiving mechanism elastically float up and down, and the transverse elastic mechanism is used to make the receiving mechanism elastically displace in the transverse direction, so that the roller seat can adapt to the transverse force on the receiving mechanism.

[0021] Furthermore, a roller changing car is provided, which arranges two transverse adaptive roller seats side by side and places a new roller on the rear transverse adaptive roller seat, so that the roller clamping mechanism can cooperate with the guide mechanism of the two front and rear transverse adaptive roller seats to complete the quick roller change.

[0022] The beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0023] The longitudinal elastic mechanism reduces the impact on the roller seat in the vertical direction; the transverse elastic mechanism allows the receiving mechanism to generate transverse elastic displacement and absorbs the transverse force generated by the cooperation of the clamping mechanism and the guiding mechanism, so that the roller seat remains stable, which not only prevents the roller seat from overturning, but also protects the structural strength of the roller seat and improves the service life of the roller seat.

[0024] In the roll changing car, the lateral adaptive roll holder can absorb lateral forces, making the replacement of old rolls and the clamping of new rolls safe and smooth, improving the efficiency of roll changing and further enhancing the safety of the entire roll changing process.

[0056] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0057] In the description of this invention, the term "at least one" means one or more, unless otherwise expressly defined. The terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0059] The specific implementation methods of this invention are as follows:

[0060] like Figure 1-2 As shown in Figure 9, this embodiment provides a lateral adaptive roller seat, which is typically used in steel plate grinding equipment located within a frame. The equipment has a steel plate grinding area s. When the upper brush roller is replaced in the roller changing channel on the side of the steel plate grinding area s, the lateral adaptive roller seat in this embodiment can prevent the roller seat from tipping over while simultaneously completing the replacement of the brush roller 4. The roller seat includes a fixing mechanism 2 and a receiving mechanism 3. The receiving mechanism 3 is positioned above the fixing mechanism 2 and can cooperate with the vertically movable clamping roller mechanism 1 to complete the roller receiving. A lateral elastic mechanism and a longitudinal elastic mechanism 22 are provided between the upper end of the fixing mechanism 2 and the lower end of the receiving mechanism 3. The longitudinal elastic mechanism 22 provides longitudinal elastic support to the receiving mechanism 3. A guiding mechanism is provided on the receiving mechanism 3. The lateral elastic mechanism can cause the receiving mechanism 3 to generate a lateral elastic displacement in the corresponding direction when the guiding mechanism cooperates with the clamping roller mechanism 1, thereby allowing the roller seat to adapt to the lateral force generated when the guiding mechanism and the clamping roller mechanism 1 cooperate.

[0061] In order to reduce the impact of the clamping roller mechanism 1 on the receiving mechanism 3 in the vertical direction when the clamping roller mechanism 1 contacts and cooperates with the guiding mechanism, a longitudinal elastic mechanism 22 is provided between the upper end of the fixed mechanism 2 and the lower end of the receiving mechanism 3. At least two longitudinal elastic mechanisms 22 are symmetrically arranged on the side between the fixed mechanism 2 and the receiving mechanism 3 in the left and right directions, so that each position of the receiving mechanism 3 can achieve the effect of shock absorption and buffering.

[0062] like Figure 18-22 As shown, specifically, the longitudinal elastic mechanism 22 is an elastic support cylinder. The elastic support cylinder includes an earring 225 that is hinged to both hinge seats 221. The earring 325 below the base 32 is locked to the cylindrical outer shell 223 by a nut 226. A support block 228 is fixed inside the outer shell 223. The support block 228 and the earring above the chassis 21 are connected by a strut 227. An elastic element 222 is sleeved on the outer wall of the strut 227. In order to absorb the impact load generated when the old roller 4a is pressed down, the elastic element 222 is usually a number of disc springs stacked side by side and close together. The tension of the chain 231 makes the disc springs tightly locked between the support block 228 and the strut 227, so that the support block 228 generates an upward preload, forming a stable support effect for the bearing mechanism 3.

[0063] Furthermore, such as Figure 21As shown, to prevent wear caused by frequent contact between the support block 228 and the disc spring, a bushing 229 is provided between the support block 228 and the disc spring. When the disc spring abuts against the support block 228, the bushing 229 can be a copper sleeve with low hardness, which can act as a buffer to prevent direct contact between the disc spring and the support block 228. The worn bushing 229 can also be directly replaced, thus avoiding wear problems and saving maintenance costs. In order to minimize wear caused by component contact, an oil nozzle 224 is provided on the outer shell 223. When maintaining the elastic support cylinder, lubricating oil can be added to the oil nozzle 224 to minimize component wear during the extension and retraction of the elastic support cylinder, thereby making the operation of the elastic support cylinder smoother.

[0064] like Figure 16 As shown, the lateral elastic mechanism includes two symmetrical lateral elastic components. Each lateral elastic component includes a cylindrical body 24 and a lateral elastic wheel 34. The cylindrical body 24 is positioned above the fixed mechanism 2, and the lateral elastic wheel 34 is connected to the lower end of the receiving mechanism 3. On the outer wall of the cylindrical body 24 in the front-back, left-right, and right-side directions, the left or right side wall is unoccupied. On the other three sides of the cylindrical body 24, there are corresponding lateral elastic wheels 34 that abut against it. This allows the receiving mechanism 3 to be subjected to a lateral force when the guide mechanism cooperates with the clamping roller mechanism 1. The lateral elastic components cause the corresponding lateral elastic wheel 34 to abut against the cylindrical body 24 and undergo elastic deformation, thereby generating a lateral elastic displacement in the corresponding direction. The lateral elastic components allow the receiving mechanism 3 to move elastically in all lateral directions, meaning the receiving mechanism 3 has a lateral elastic displacement margin. After the receiving mechanism 3 is subjected to a lateral force, the lateral elastic components absorb the lateral force and provide lateral elastic support to the receiving mechanism 3, allowing the receiving mechanism 3 to return to its lateral position.

[0065] Furthermore, the transverse elastic wheel 34 includes a buffer base 346 installed below the base 32. A buffer assembly is connected to the buffer base 346 by screws. The buffer assembly includes a buffer seat 343 and a rotating wheel 341. The rotating wheel 341 is hinged to the buffer seat 343 by a third pin 342. An elastic buffer element 345 is provided between the buffer seat 343 and the buffer base 346. When a large external force is applied to the rotating wheel 341, in order to enable the elastic buffer element 345 to provide sufficient rebound force, the elastic buffer element 345 is usually a mold spring or disc spring made of metal material.

[0066] like Figure 1-10As shown, the clamping roller mechanism 1 is controlled by a drive element and can slide and translate in the up, down, left, and right directions. The drive element (not shown) is usually a controlled hydraulic component, such as a hydraulic cylinder or a hydraulic pump. The clamping roller mechanism 1 includes a stationary mechanism 102 and a sliding mechanism 101. An old roller 4a is axially fixed and circumferentially rotated between the stationary mechanism 102 and the sliding mechanism 101. The axis of the old roller 4a is in the left and right direction. The sliding mechanism 101 can slide in the left and right direction to install or disengage the old roller 4a on the clamping roller mechanism 1.

[0067] Furthermore, the stationary mechanism 102 and the sliding mechanism 101 are equivalent to the bearing seat of the old roller 4a. The left end of the bearing seat is the stationary mechanism 102, which is stationary and does not move. A motor is connected to the left end of the stationary mechanism 102. The motor drives the components in the fixed mechanism, so that the old roller 4a can rotate circumferentially, thereby brushing the surface of the steel plate. The sliding mechanism 101 at the right end of the bearing seat is a sliding bearing seat controlled by a cylinder or a hydraulic cylinder. The sliding position of the sliding bearing seat can be controlled by controlling the extension and retraction of the cylinder or hydraulic cylinder. The left and right sliding of the sliding mechanism 101 is controlled by a control unit (not shown). For example, the control unit can be a master controller. Only when the control unit sends a command will the hydraulic cylinder or cylinder in the sliding mechanism 101 pull the bearing seat to slide. When the sliding mechanism 101 slides to the right end of the old roller 4a, the left and right ends of the old roller 4a are clamped. When the sliding mechanism 101 slides to the right, the right end of the old roller 4a loses its support point for circumferential rotation, thereby causing the old roller 4a to disengage from the clamping roller mechanism 1.

[0068] Furthermore, such as Figure 1-10As shown, the sliding mechanism 101 in the roller clamping mechanism 1 is controlled by a control unit (not shown). When the old roller 4a is placed on the receiving seat 31, the control unit sends a command to the sliding mechanism 101 to slide to the right and disengage from the right end of the old roller 4a. At this time, the left end of the old roller 4a is still connected to the stationary mechanism 102. The reason for not setting a sliding mechanism 101 on the left end of the roller clamping mechanism 1 is that the stationary mechanism 102 on the left end is connected to a motor. The motor drives the old roller 4a to rotate and grind the steel plate. Since the presence of the motor already occupies the axial space of the roller clamping mechanism 1, making the left end of the roller clamping mechanism 1 a sliding mechanism would make the axial structure of the roller clamping mechanism 1 bulky. Repeated sliding will also cause the motor and the old roller 4a to frequently connect and disconnect. In order to ensure good fit at the connection between the motor and the old roller 4a, a positioning mechanism must be added again, which will increase the processing difficulty, design difficulty and manufacturing cost. Therefore, in order to disconnect the left end of the old roller 4a, a telescopic member 312 is symmetrically set at the left end of the receiving seat 31. The telescopic rod 313 inside the telescopic member 312 extends out and abuts against the vertical plate at the end of the fixing mechanism 101. At this time, the clamping roller mechanism 1 is in a stationary state. After being abutted by the telescopic rod 313, it will generate a reaction force on the receiving seat 31. The receiving seat 31 will slide to the right along the guide rail 321, disconnecting the left end of the old roller 4a.

[0069] Furthermore, such as Figure 27 As shown, in order to ensure that the telescopic component 312 can remain stable and not wobble when it extends, a protective pipe seat 311 is provided below the telescopic component 312. The protective pipe seat 311 has a hollow structure and a hydraulic oil pipe connected to the telescopic component 312 passes through it. A support plate is installed on the protective pipe seat 312, and the lower part of the extended end of the telescopic component 312 is fixed to the support plate so that the telescopic component 312 can be stably supported when it extends.

[0070] The receiving mechanism 3 includes a receiving seat 31 and a base 32. The receiving seat 31 is arranged above the base 32 and can receive the brush roller 4. In order to allow the receiving seat 31 to be smoothly adjusted in position when receiving the brush roller 4 and to be centered on the base 32, a guide groove 316 is provided below the receiving seat 31, and a guide rail 321 extending in the left-right direction is provided on the base 32. The guide groove 316 cooperates with the guide rail 321, allowing the receiving seat 31 to slide in the left-right direction on the base 32 and relative to the base 32 in the left-right direction.

[0071] Furthermore, to improve the adjustment speed, given that the receiving seat 31 can slide left and right, a roller telescopic component 322 is provided on the base 32, which is typically a cylinder. A sliding rod 323 is provided inside the roller telescopic component 322, which can extend or retract in the left and right directions. The roller telescopic component 322 is connected to a T-shaped connecting sleeve 315 located below the receiving seat 31 via the T-shaped head of the sliding rod 313, allowing the position of the receiving seat 31 to be controlled by the roller telescopic component 323. A stroke limiting seat 317 is provided at a corresponding position below the receiving seat 31. When the roller telescopic component 322 extends, the guide groove 316 below the receiving seat 31 engages with the guide rail 321 on the base 32, causing the receiving seat 31 to slide left and right. The cylinder bottom of the roller telescopic component 322 abuts against the stroke limiting seat 317, keeping the receiving seat 31 in place.

[0072] like Figure 18-22 As shown, since the cooperation of the clamping roller mechanism 1 and the guiding mechanism will inevitably cause the receiving mechanism 3 to undergo lateral displacement, in order to prevent the connection of the longitudinal support structure 22 from being pulled when the receiving mechanism 3 moves laterally elastically, the base 32 and the fixing mechanism 2 are both provided with hinge seats 221. The upper and lower ends of the longitudinal elastic mechanism 22 are respectively hinged to the hinge seats 221 below the receiving mechanism 3 and above the fixing mechanism 2. When the guiding mechanism cooperates with the clamping roller mechanism 1, the upper and lower ends of the longitudinal elastic mechanism 22 rotate, causing the receiving mechanism 3 to undergo lateral elastic displacement and longitudinal deflection at the same time. At this time, the lateral elastic wheel 34 in the corresponding direction abuts against the cylindrical body 24 and undergoes elastic deformation, so that the receiving mechanism 3 adapts to the lateral force while forming a deflection elastic support force on the receiving mechanism 3; thus preventing the receiving mechanism 3 from tipping over above the fixing mechanism 2.

[0073] The guiding assembly includes left and right guiding assemblies and front and rear guiding assemblies. These assemblies are symmetrically arranged between the clamping roller mechanism 1 and the receiving mechanism 3. The left and right guiding assemblies and the front and rear guiding assemblies all utilize a contact surface pressing mechanism to induce lateral elastic displacement in the receiving mechanism 3, gradually aligning it with the clamping roller mechanism 1. Specifically, as... Figure 11 As shown, the left and right guide components include a guide support 35 with a Y-shaped groove 351 mounted on the receiving mechanism 3 and a circumferentially rotatable guide post 107 mounted on the clamping roller mechanism 1. The opening of the Y-shaped groove 351 is connected to the top of the guide support 35, thereby forming two symmetrical inclined surfaces on the guide support 35. The guide post 107 contacts and rotates with the inclined surfaces, thereby guiding the guide post 107 to the lower part of the Y-shaped groove 351 and causing the transverse elastic wheel 34 at the lower end of the receiving mechanism 3 to undergo elastic deformation in the left and right directions. This allows the receiving mechanism 3 to align with the clamping roller mechanism 1 while generating elastic displacement in the left and right directions, enabling the receiving mechanism 3 to adapt to the transverse force in the left and right directions.

[0074] Furthermore, such as Figure 11-13 As shown, the front and rear guide components are symmetrically arranged on the front and rear sides of the roller seat. The front and rear guide components include an elastic swing wheel 33 and a guide plate 103. The elastic swing wheel 33 is arranged on the receiving mechanism 3 and can be elastically deflected in the front and rear relative to the receiving mechanism 3. The guide plate 103 is arranged on the clamping roller mechanism 1. The guide plate 103 is provided with a guide inclined surface 104. The guide inclined surface 104 is pressed and engaged with the elastic swing wheel 33, causing the elastic swing wheel 33 to rotate and be elastically deflected. This causes the transverse elastic wheel 34 at the lower end of the receiving mechanism 3 to undergo elastic deformation in the front and rear direction, so that the receiving mechanism 3 is aligned with the clamping roller mechanism 1 and generates elastic displacement in the front and rear direction, allowing the receiving mechanism 3 to adapt to the transverse force in the front and rear direction.

[0075] Furthermore, to prevent the receiving mechanism 3 from horizontally twisting when the guide plate 103 engages with the elastic swing wheel 33, guide support plates 105 are symmetrically arranged on the front and rear sides of the clamping roller mechanism 1. Near the guide support plates 105, the base 32 is also correspondingly provided with elastic swing wheels 33. When the guide plate 103 engages with the elastic swing wheel 33, the guide support plate 105 contacts the elastic swing wheel 33, providing a stable engagement support point for the downward movement of the clamping roller mechanism 1, allowing the clamping roller mechanism 1 to move smoothly up and down, thereby ensuring that the contact surface between the guide plate 103 and the elastic swing wheel 33 is continuously squeezed, completing the engagement between the clamping roller mechanism 1 and the receiving mechanism 3.

[0076] Furthermore, such as Figure 23-25As shown, conventional guide wheels rely on the elastic deformation of their own material for guidance. However, when the guide wheel is subjected to a large compressive load, the material itself may break. Therefore, in this embodiment, the guidance of the clamping roller mechanism 1 is mainly achieved through an elastic swing wheel 33. The elastic swing wheel 33 includes a rotating base 338 fixed on the base 32. A swing assembly is hinged to the rotating base 338 via a second pin 334. The swing assembly includes a swing seat 332. A rotatable guide wheel 331 is hinged to the swing seat 332 via a first pin 333. The guide wheel 331 is usually made of rubber with good resilience. In order for the guide wheel 331 to rotate and generate elastic compression when squeezed by the fixing mechanism 1, A connecting shaft 339 is fixed on the swing seat 332. The mounting plate 336 and the connecting shaft 339 are connected by bolts. On the outside of the bolts, an elastic telescopic member 337 in a compressed state is sleeved. The elastic telescopic member 337 is usually a mold spring or disc spring to cope with the large load generated by the extrusion force. A horizontal plate 335 is provided on the base 338. When the guide wheel 331 and the swing seat 332 are not squeezed by the guide plate 103, the swing seat 332 will abut against the horizontal plate 335. When the guide wheel 331 and the swing seat 332 are squeezed by the guide plate 103, the swing seat 332 and the guide wheel 331 will elastically swing relative to the base 338. The guide wheel 331 and the swing seat 332 have a swing angle b relative to the base 338. The swing angle b is usually 3°-10°.

[0077] like Figure 11-2As shown in Figure 9, the clamping roller mechanism 1 engages with the front and rear guide components and the left and right guide components simultaneously during operation. This means that the receiving mechanism 3 is simultaneously subjected to lateral forces in both the left and right and front and rear directions. This causes the receiving mechanism 3 to generate elastic displacement in both the front and rear directions and in the left and right directions. However, if the elastic swing wheel 33 in the front and rear guide components is subjected to both rolling friction and sliding friction generated by the left and right movement of the receiving mechanism 3, the guide plate 103 will generate an oblique resultant force on the elastic swing wheel 33. This will make it difficult for the elastic swing wheel 33 to slide left and right on the guide plate 103, thus hindering the process of the receiving mechanism 3 generating lateral elastic displacement in the left and right directions. Therefore, in order to allow the guide plate 103 to slide left and right with the receiving mechanism 3 and to protect the structural strength of the elastic swing wheel 33, the guide slope 104 of the guide plate 103 extends upward and intersects with the vertical plane 109 of the guide plate 103. The lower end of the vertical plane 109 extends inward. The elastic swing wheel 33 contracts downwards, forming a support slope 108 on the guide plate 103. After the elastic swing wheel 33 is guided by the guide slope 104, the guide post 107 is pressed against the slope on the Y-shaped slot 351, causing the receiving mechanism 3 to produce elastic displacement in the left and right directions. At this time, the elastic swing wheel 33 simultaneously contacts the vertical plane 109 and the support slope 108 and stops rotating. The vertical plane 109 and the support slope 108 are tangent surfaces that simultaneously contact the elastic swing wheel 33. When the elastic swing wheel 33 rolls along the vertical plane 109, it suddenly contacts the support slope 108, which is equivalent to its rotation trend being blocked by the support slope 108. The elastic swing wheel 33, which stops rotating, will not generate rolling friction. At the same time, the vertical plane 109 and the support slope 108 provide the elastic swing wheel 33 with an upper support point J and a lower support point K in the vertical direction, respectively. These two support points make the elastic swing wheel 33 slide more smoothly in the left and right directions relative to the guide plate 103 under the drive of the receiving mechanism 3.

[0078] like Figure 15 As shown, although the lateral elastic mechanism can support the deflected receiving mechanism 3, the receiving mechanism 3 will inevitably still have a slight horizontal deflection after relying solely on the lateral elastic mechanism to restore the receiving mechanism 3 to a horizontal position. Therefore, a leveling mechanism is symmetrically provided at the four diagonal positions between the clamping roller mechanism 1 and the receiving mechanism 3. The leveling mechanism includes a top block 106 and a top column 36 respectively provided on the clamping roller mechanism 1 and the receiving mechanism 3. When the receiving mechanism 3 deflects horizontally, the clamping roller mechanism 1 continues to descend until the top block 106 in the leveling mechanism and the top column 36 at the corresponding position come into contact, thereby restoring the receiving mechanism 3 to a horizontal state.

[0079] To prevent the receiving mechanism 3 from swaying up and down on the longitudinal elastic mechanism 22, the longitudinal elastic mechanism 22 is symmetrically arranged between the upper end of the fixed mechanism 2 and the lower end of the receiving mechanism 3. The elastic mechanism 22 is in a compressed state under the action of the tension member, thereby generating an upward pre-tightening support force on the receiving mechanism 3, keeping the receiving mechanism 3 in a horizontal state. The tension member is a chain 231 arranged on the side of the longitudinal elastic mechanism 22. The two ends of the chain 231 are connected to the receiving mechanism 3 and the fixed mechanism 2 respectively and are always kept taut, so that the longitudinal elastic mechanism 22 is in a compressed state. The taut chain 231 can continuously tighten the receiving mechanism 3. When the receiving mechanism 3 needs to connect to the roller, the chain 231 will instantly relax, without interfering with the roller connection process.

[0080] Based on the lateral adaptive roller holder, a roller changing trolley is further provided, including two lateral adaptive roller holders arranged side by side in the front-rear direction. The receiving mechanism 3 of the front roller holder is kept unloaded, while the receiving mechanism 3 of the rear roller holder is equipped with a new roller 4b. The fixing mechanism 2 of the two roller holders is connected by screws or welding to form a chassis 21, which can drive the roller holders to move in the front-rear direction. After the roller clamping mechanism 1 cooperates with the guide mechanism on the front roller holder to receive the old roller 4a, the chassis 21 moves forward, aligning the rear roller holder with the roller clamping mechanism 1, and then the new roller 4b is clamped by the roller clamping mechanism 1 cooperating with the guide mechanism on the rear roller holder again. This avoids the influence of lateral force on the roller holders during the roller changing process and improves the efficiency of roller changing.

[0081] In this invention, the old roller 4a and the new roller 4b are of the same size. When they are placed on the receiving seat 31, both ends of them are restricted in their left and right directions by the fixing blocks 314 corresponding to those on the receiving seat 31. The only difference is that the old roller 4a is an old roller that has been used in the steel plate brushing area s, and the mechanisms for receiving the old roller 4a and the new roller 4b are the front empty receiving seat 31 and the rear receiving seat 31, respectively. The left side of the empty receiving seat 31 is provided with a telescopic component 312, which is usually a hydraulic cylinder. The telescopic component 312 contains a telescopic rod 313, which can extend or retract in the left and right directions. 3 is an auxiliary component for the left end of the old roller 4a to disengage from the stationary mechanism 102; on the receiving seat 31 on the rear side where the new roller 4b is installed, the telescopic component 313 does not participate in the roller loading process, so the rear receiving seat 31 may not be equipped with the telescopic component 31. However, in this embodiment, in order to ensure the universality of the receiving mechanism 2 in the new receiving seat and to facilitate the maintenance and management of the receiving mechanism 2, the rear receiving seat 31 is configured the same as the front empty receiving seat 31. That is to say, in this embodiment, both the rear receiving seat 31 and the front empty receiving seat 31 can receive the old roller 4a and the new roller 4b, and can work normally even if their positions are changed.

[0082] like Figure 17-21As shown, pulleys are provided on the left and right sides of the chassis 21, and a motor is provided at the rear of the chassis 21. The motor and the connecting mechanism drive the pulleys to drive the fixing mechanism 2 to slide on the slide rail a. In order to keep the direction of the fixing mechanism 2 of the new type of support unchanged during movement, a slide rail a is also provided on the ground. The slide rail a separates the new type of support from the ground, so that the fixing mechanism 2 can move forward more smoothly on the slide rail a, without worrying about the new type of support deflecting.

[0083] like Figure 7-8 As shown, the process of clamping the new roller 4b is to use the driving element to control the clamping mechanism 1 to move upward and move the fixing mechanism 2 forward, then control the clamping mechanism 1 to move downward to the left and right sides of the new roller 4b, and then control the sliding mechanism 101 to move to the left, so that the right end and left end of the new roller 4b are respectively locked into the sliding mechanism 101 and the stationary mechanism 102.

[0084] like Figure 17 As shown, in order to keep the chassis 21 fixed during the unloading roller guide and clamping roller guide, a positioning structure is provided between the fixing mechanism 2 and the ground. The positioning structure includes a positioning telescopic component 211 and a positioning seat d. The positioning telescopic component 211 is set on the chassis 21 of the fixing mechanism 2 and can extend and retract vertically. The positioning telescopic component 211 is usually a cylinder, and a positioning telescopic rod 212 is set inside it. The head of the positioning telescopic rod 212 is V-shaped. The positioning seat d is fixed on the ground and has a V-shaped groove on the top. During the unloading roller guide and clamping roller guide steps, when the fixing mechanism 2 needs to stop, the head of the positioning telescopic rod 212 is inserted into the V-shaped groove, so that the fixing mechanism 2 remains fixed front and back.

[0085] like Figure 22As shown, when the old roller 4a is placed on the receiving seat 31, the disc spring in the longitudinal elastic mechanism 22 is compressed, and the chain 231 switches to the relaxed state. When the new roller 4b is removed from the receiving seat 31, the chain 231 switches back to the tensioned state. By controlling the tension of the chain 231, it is possible to better determine whether the brush roller 4 is properly placed on the receiving seat 31. The tension and relaxation states of the chain 321 are switched instantaneously under the condition of gravity change. Utilizing this characteristic, it can have a similar function to an open... The control function of the device can be implemented by setting at least one switch assembly 23 on the chassis of the fixed mechanism 2. The switch assembly 23 includes a rotating base 232 and a switching element c. The switching element c is set on a bracket 235 on the side of the rotating base 232. At least one chain 231 connecting the base 32 of the supporting mechanism 3 and the chassis 21 of the fixed mechanism 2 is hinged to the rotating base 232 at its lower part. The rotating base 232 is hinged to the mounting base 234 of the chassis 21. The rotating base 232 has a front... The extended rotating plate 236, the rotating seat 232 and the fixed mechanism 2 are provided with an elastic element 233. The elastic element 233 can be a tension spring hooked between the rotating seat 232 and the chassis 21, or a torsion spring hinged between the rotating seat 232 and the chassis 21. During the unloading of the roller, when the chain 231 is in a relaxed state, the elastic element 233 will undergo elastic deformation, causing the rotating seat 232 to rotate downwards. The action signal is sent to the control unit through the switching element c. The control unit issues a command to make the sliding mechanism 1 01 Slide to the right to disengage the right end of the old roller 4a from the sliding mechanism 101, and proceed with the remaining roller unloading operations. When loading the roller, the chain 231 will only change its state after the new roller 4b is clamped and disengaged from the receiving seat 31. Therefore, although the receiving mechanism 3 that places the new roller 4b at the rear is configured the same as the receiving mechanism 3 at the front, this is only to consider the commonality between the receiving mechanisms 3. The chain 231 and the switch assembly 23 do not participate in the control of the sliding mechanism 101 during the roller loading process.

[0086] Furthermore, the positioning telescopic component 211 is controlled by a receiving unit (not shown). The receiving unit can be a sub-controller. When the fixing mechanism 2 needs to slide to load the roller, the telescopic rod 313 of the telescopic component 312 on the receiving seat 31 with the old roller 4a mounted in front retracts. At the side of the telescopic rod 313, a detection element e is provided on the tube holder 311. By utilizing the contact cooperation between the telescopic rod 313 and the detection element e, the telescopic rod 313 can have the function of controlling the state of the fixing mechanism 2. When the telescopic rod 313 retracts, the rod head triggers the detection element e, and the detection element e will send an action signal to the receiving unit, causing the positioning telescopic rod 212 to retract and disengage from the positioning seat d, thereby causing the fixing mechanism 2 to move forward.

[0087] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
