Description

Technical Field

[0001] This invention relates to the field of metal surface treatment, and particularly to a floating roller seat and its application. Background Technology

[0002] After steel plates are produced, 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 required. During this time, the steel plates will react with moisture and chemicals in the air, causing the surface material of the steel plates to peel off or rust. The earliest method to remove the rust layer was to pickle the surface of the steel plates, but this method is costly and polluting. Therefore, grinding equipment that removes rust by brushing the surface of the steel plates has emerged. This equipment uses brush rollers to physically grind the surface of the steel plates, which improves the efficiency of rust removal and reduces pollution, and has therefore been well received. However, this equipment requires the brush rollers to contact the surface of the steel plates during grinding. After long-term use, the grinding effect of the brush rollers will also decrease. Therefore, the brush rollers need to be placed on the roller changing car for replacement with new rollers. However, due to the large mass of the brush rollers, they are prone to impact with the support device when they fall onto the support device, which can damage the brush rollers or the support device. The roller seats on the existing roller changing devices do not take these problems into account.

[0003] For example, in the roller changing device patent with publication number CN216371699, such as in the patent... Figures 1-12 As shown, the support seat for the brush roller can move forward or backward along the guide rail along the length of the support seat under the drive of the roller changing drive assembly. However, no buffer mechanism is set under the support seat. When the brush roller falls onto the support seat, the component that contacts the lower end of the brush roller is the support member 43, which is a guide wheel. Although the guide wheel itself has a certain elastic deformation capacity, it is not enough to produce a corresponding buffering effect on the falling brush roller. Under the gravity impact of a large mass brush roller, the guide wheel is likely to deform or even break. Even if the strength of the guide wheel is sufficient to support the brush roller, the rigid support seat design will inevitably cause the brush roller to elastically bounce on the support seat when the brush roller is placed on it, causing impact on the brush roller and the support seat, affecting the service life of the support seat and the brush roller. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a floating roller seat. By hinged an elastic support mechanism in a compressed state between the support mechanism and the fixing mechanism, the elastic support mechanism is further compressed when the brush roller falls onto the support mechanism. Simultaneously, the upper and lower ends of the elastic support mechanism rotate to form a floating support for the brush roller. This absorbs the impact of the brush roller's gravity and prevents the brush roller from bouncing on the support mechanism, thereby reducing noise and improving the service life of both the brush roller and the support mechanism.

[0005] Furthermore, a floating roller seat application is provided. By arranging two supporting mechanisms side by side on a fixed mechanism and setting an elastic support mechanism therein, the floating support effect of the floating roller seat is used to cooperate with the clamping roller mechanism to complete the unloading and clamping of the roller, avoiding direct collision or impact between the brush roller and the supporting mechanism, making the entire roller changing process both safe and efficient.

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

[0007] A floating roller seat includes a fixing mechanism and a supporting mechanism. The supporting mechanism is mounted on the fixing mechanism and can support the brush roller. An elastic support mechanism is provided between the upper end of the fixing mechanism and the lower end of the supporting mechanism. The upper and lower ends of the elastic support mechanism are respectively hinged to the supporting mechanism and the fixing mechanism. The elastic support mechanism is in a compressed state, thereby generating an upward supporting force on the supporting mechanism. A deflection support mechanism is provided between the fixing mechanism and the supporting mechanism. The deflection support mechanism can form elastic support when the supporting mechanism deflects relative to the horizontal plane.

[0008] The roller holder has a stable state and a floating state. When the roller holder is in the stable state, the support mechanism remains unloaded, and the supporting force generated by the elastic support mechanism keeps the support mechanism horizontal. When the brush roller is placed on the support mechanism, the elastic support mechanism is further compressed, and the upper and lower ends of the elastic support mechanism rotate, causing the support mechanism to deflect relative to the horizontal plane, and the deflection support mechanism provides elastic support to the support mechanism. At this time, the roller holder is in the floating state. When the brush roller is removed from the support mechanism, the elastic support mechanism returns to the initial compressed state and generates supporting force again, causing the support mechanism to return to the horizontal state. At this time, the roller holder switches back to the stable state.

[0009] Preferably, the fixing mechanism remains fixed in the vertical direction, but can move freely relative to the ground in the front-back direction; this facilitates the movement of the supporting mechanism to the designated position for brush roller support.

[0010] Preferably, the deflection support mechanism is symmetrically arranged between the fixed mechanism and the support mechanism. The deflection support mechanism includes a cylindrical body and elastic reset wheels, with the elastic reset wheels connected to the lower end of the support mechanism. On the outer wall surface 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, there are corresponding elastic reset wheels abutting against it. When the roller seat is in a floating state, the support mechanism deflects relative to the horizontal plane, and the corresponding elastic reset wheels undergo elastic deformation, generating a deflection support force on the support mechanism, causing the deflected support mechanism to return to a horizontal position. This prevents the brush roller from tipping over due to excessive deflection of the support mechanism.

[0011] Preferably, the support mechanism includes a support seat and a base, with the support seat arranged above the base. The support seat can receive the brush roller and can slide relative to the base in the left-right direction, thereby facilitating the adjustment of the position of the support seat so that it is in the center position of the support mechanism when receiving the brush roller.

[0012] Preferably, the support is provided with a guide groove below and a guide rail extending in the left and right direction on the base. The guide groove and the guide rail cooperate to allow the support to slide in the left and right direction on the base. The cooperation between the guide groove and the guide rail makes the support slide more smoothly and avoids the problem of jamming between the support and the base.

[0013] Preferably, the base is provided with a roller telescopic component, which can extend or retract in the left and right directions; the roller telescopic component is connected to the lower part of the support seat and can drive the support seat to slide in the left and right directions; by utilizing the extension and retraction of the roller telescopic component, the position of the support seat can be quickly adjusted, saving the time of adjusting the position of the support seat.

[0014] Preferably, the roller seat has at least two elastic support mechanisms symmetrically arranged on the side between the fixing mechanism and the supporting mechanism in the left-right direction; this makes the elastic support mechanism provide more uniform elastic support and buffering effect on the supporting mechanism.

[0015] Preferably, at least two chains are symmetrically arranged between the supporting mechanism and the fixing mechanism. When the roller seat is in a stable state, the chains are kept taut under the supporting elastic force generated by the elastic support mechanism. When the roller seat is in a floating state, the chains switch to a relaxed state. By utilizing the change of gravity, the chains present different tension states. By judging the tension state of each chain, it can be confirmed whether the brush roller is placed in place on the supporting mechanism.

[0016] Preferably, the fixing mechanism is provided with at least one switch assembly, which includes a rotating seat and a switch element c; at least one chain connecting the supporting mechanism and the fixing mechanism is hinged at the bottom to the rotating seat; an elastic element is provided between the rotating seat and the fixing mechanism, and when the chain is in a relaxed state, the elastic element undergoes elastic deformation, causing the rotating seat to rotate downward, thereby triggering the switch element c; by utilizing the characteristic of the chain being taut under force and instantly relaxed when no force is applied, it is connected to the rotating seat, thereby making the triggering process of the switch element more sensitive.

[0017] This further provides an application of a floating roller seat, including:

[0018] S1: Pre-place the new roller; arrange the two support mechanisms side by side on the fixed mechanism, and set the elastic support mechanism between the upper end of the fixed mechanism and the lower end of the two support mechanisms; then place the new brush roller on the rear support mechanism in advance, and make the fixed mechanism move to the unloading position of the clamping roller mechanism.

[0019] S2: Floating unloading roller; The clamping roller mechanism clamps the old brush roller and places it on the support mechanism, which further compresses the elastic support mechanism. The upper and lower ends of the elastic support mechanism rotate, which at the same time drives the support mechanism to deflect along the horizontal plane, so that the old brush roller floats on the support mechanism first and then gradually becomes stable on the support mechanism.

[0020] S3: Roller reset; The fixed mechanism moves forward to the roller loading station, the unloaded roller clamping mechanism moves down to clamp the new brush roller and disengage it from the support mechanism. At this time, the elastic support mechanism resets and generates support elasticity, causing the support mechanism to return to a horizontal state.

[0021] Preferably, in step S3, before the clamping roller completely leaves the supporting mechanism, the compression of the elastic support mechanism continues to decrease, and the released restoring force causes the supporting mechanism to press against the new brush roller upward, thereby forming a following support for the new brush roller; thus providing support force for the brush roller during roller loading, making it easier for the clamping roller mechanism to clamp the new brush roller.

[0022] The principle of the present invention, which adopts the above technical solution, is as follows:

[0023] The present invention first provides a floating roller seat, which is a compressed elastic support mechanism hinged between the support mechanism and the fixing mechanism. When the brush roller falls onto the support mechanism, the elastic support mechanism is further compressed, and at the same time, the upper and lower ends of the elastic support mechanism rotate to form a floating support for the brush roller.

[0024] Furthermore, a floating roller seat application is provided, in which two supporting mechanisms are arranged side by side on a fixed mechanism, and an elastic support mechanism is set therein. The floating support effect of the floating roller seat is used to cooperate with the clamping mechanism to complete the unloading and clamping of the roller.

[0025] The beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0026] The elastic support mechanism in the floating roller seat buffers the impact force of the brush roller through elastic deformation when the support mechanism supports the brush roller. It can also rotate up and down, causing the support mechanism to deflect slightly, so that the brush roller will not bounce upwards. This minimizes the impact between the brush roller and the support mechanism and protects the structural strength of the brush roller and roller seat from being affected.

[0027] In the application of floating roller seats, the roller clamping mechanism works in conjunction with the floating roller seat so that the floating roller seat can buffer and dampen the brush roller during the process of unloading the brush roller and clamping the new brush roller, thereby reducing the noise generated by the brush roller impact and making the entire roller changing process safe and efficient.

Detailed Implementation

[0057] 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.

[0058] 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.

[0059] 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.

[0060] The specific implementation methods of this invention are as follows:

[0061] like Figure 1-28As shown, this embodiment provides a floating roller seat, which is typically used in steel plate brushing equipment located within a frame. The equipment has a steel plate brushing area s. When the upper brush roller is replaced in the side roller changing channel of the steel plate brushing area s, the floating roller seat in this embodiment can provide buffering and shock absorption. The roller seat includes a fixing mechanism 2 and a supporting mechanism 3. The supporting mechanism 3 is disposed on the fixing mechanism 2 and can support the brush roller 4. Specifically, the supporting mechanism 3 includes a supporting seat 31 and a base 32. The supporting seat 31 is arranged above the base 32 and can support the brush roller 4. In order to allow the supporting seat 31 to be smoothly adjusted in position when supporting the brush roller 4 and to be in the center position of the base 32, a guide groove 316 is provided below the supporting seat 31, and a guide rail 321 extending in the left and right direction is provided on the base 32. The guide groove 316 cooperates with the guide rail 321 so that the supporting seat 31 can slide in the left and right direction on the base 32. It can slide relative to the base 32 in the left and right directions.

[0062] Furthermore, to improve the adjustment speed, given that the support 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 support 31 via the T-shaped head of the sliding rod 313, allowing the position of the support 31 to be controlled by the roller telescopic component 323. A stroke limiting seat 317 is provided at a corresponding position below the support 31. When the roller telescopic component 322 extends, the guide groove 316 below the support 31 engages with the guide rail 321 on the base 32, causing the support 31 to slide left and right. The cylinder bottom of the roller telescopic component 322 abuts against the stroke limiting seat 317, keeping the support 31 in place.

[0063] like Figure 17-21 As shown, a moving fixing mechanism 2 is provided below the base 32. The fixing mechanism 2 remains fixed in the vertical direction and can move freely relative to the ground in the front-back direction. The fixing mechanism 2 includes a frame-shaped walking chassis 21. Pulleys are provided on the left and right sides of the walking chassis 21. A motor is provided at the rear of the walking chassis 21. The motor and the connecting mechanism drive the pulleys to move the fixing mechanism 2 on the slide rail a. In order to keep the direction of the fixing mechanism 2 of the new support unchanged during movement, a slide rail a is also provided on the ground. The slide rail a separates the new 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 support deflecting.

[0064] In order to prevent the brush roller 4 from colliding or bouncing with the support 31 when it is placed on the support 31, an elastic support mechanism 22 is provided between the upper end of the fixing mechanism 2 and the lower end of the support mechanism 3. At least two elastic support mechanisms 22 are symmetrically arranged on the side between the fixing mechanism 2 and the support mechanism 3 in the left-right direction, so that each position of the support mechanism 3 can achieve a buffering effect.

[0065] The upper and lower ends of the elastic support mechanism 22 are hinged to the support mechanism 3 and the fixing mechanism 2, respectively; and the elastic support mechanism 22 is in a compressed state. Due to the gravity transmission of the brush roller 4 to the elastic support mechanism 22, an upward supporting elastic force is generated on the support mechanism 3.

[0066] Specifically, both the base 32 and the fixing mechanism 2 are equipped with hinge seats 221. The elastic support mechanism 22 includes multiple elastic support cylinders. Each 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 traveling 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 brush roller 4a is pressed down, the elastic element 222 is usually multiple and parallel. The disc springs are stacked and close together. The gravity of the support mechanism 3 makes the disc springs tightly locked between the support block 228 and the support rod 227, so that the support block 228 generates an upward preload, forming a stable support effect on the support chassis 32 and the support seat 31. When the old brush roller 4a is placed on the support seat 31 in front, the upper and lower ends of the elastic support cylinder rotate. At the same time, the pressure transmitted by the old brush roller 4a causes the disc spring to undergo elastic deformation, forming a buffering and shock absorption effect in the vertical direction and the axial direction of the old brush roller 4a, thereby reducing the impact of the old brush roller 4a on the support mechanism 3 and ensuring that the old brush roller 4a will not jump when it is removed.

[0067] Furthermore, since the old brush roller 4a cannot be absolutely placed in the center of the support 31 when it is placed on the front support 31, the support mechanism 3 will inevitably deflect slightly. If the base 32 and the traveling chassis 21 are rigidly connected, that is, welded or threaded, the connection will inevitably be affected by the stress generated by the deflection. After repeated occurrences, the connection may crack or break. Therefore, the upper and lower ends of the elastic support cylinder are designed to be hinged. The hinged design can also meet and support the falling old brush roller 4a, so that the entire support mechanism 3 can provide floating support for the old brush roller 4a while protecting the support mechanism 3 and the fixing mechanism 2 to the greatest extent.

[0068] 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.

[0069] The roller seat has a stable state and a floating state. When the roller seat is in the stable state, the support mechanism 3 remains unloaded, and the support force generated by the elastic support mechanism 22 keeps the support mechanism 3 horizontal. When the brush roller 4 is placed on the support mechanism 3, the elastic support mechanism 22 is further compressed, and the upper and lower ends of the elastic support mechanism 22 rotate, causing the support mechanism 3 to deflect slightly relative to the horizontal plane. At this time, the roller seat is in the floating state. When the brush roller 4 is removed from the support mechanism 3, the elastic support mechanism 22 returns to the initial compressed state and generates support force again, causing the support mechanism 3 to return to the horizontal state. At this time, the roller seat switches back to the stable state.

[0070] Specifically, such as Figure 12-16 As shown, to avoid the swaying problem caused by excessive deflection angle of the support mechanism 3, two deflection support mechanisms are symmetrically arranged on the left and right sides above the fixed mechanism 2. The deflection support mechanism includes a column 24 and an elastic reset wheel 34. The elastic reset wheel 34 is connected to the base 32 at the lower end of the support mechanism 3. In the outer wall surface of the column 24 in the front-back and left-right directions, the left or right wall surface is empty. On the other three wall surfaces of the column 24, there are corresponding elastic reset wheels 34 that abut against it. When the guide slope 104 and the elastic swing wheel 33 are pressed together, the base 32 will generate a movement tendency in the front-back direction, and drive the elastic reset wheel 34 to generate elastic deformation. It is equivalent to the elastic reset wheel 34 absorbing the excess deflection force and forming an elastic support effect on the base 32, so that the support seat 31 and the brush roller 4 return to the horizontal state again, and prevent the brush roller 4 from tipping over on the support mechanism 3.

[0071] Furthermore, such as Figure 16As shown, the elastic reset 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. In addition to providing reverse support elastic force to the base 32, the elastic reset wheel 34 can also use the good elasticity of the mold spring or disc spring to generate elastic force on the base 32 in the front-back and left-right directions, so that the base 32 is fixed in the front-back and left-right directions, so as to install the base 31 and the elastic support mechanism 22.

[0072] like Figure 11 As shown, the guiding effect of the clamping roller mechanism 1 and the supporting mechanism 3 in the left and right directions is achieved as follows: the left and right guide members are guide seats 35 with Y-shaped grooves 351. The opening of the Y-shaped grooves 351 is connected to the top of the guide seat 35, thus forming two symmetrical inclined surfaces on the guide seat 35. The clamping roller mechanism 1 is provided with circumferentially rotatable guide posts 104 at corresponding positions. When the clamping roller mechanism 1 carries the old brush roller 4a down to the supporting seat 31, the guide posts 104 contact the inclined surfaces and rotate, squeezing... The pressure causes the support 31 to slide in the left and right direction. To make the sliding process smoother, a guide groove 316 is provided below the support 31, and a guide rail 321 extending in the left and right direction is provided on the base 32. When the guide post 104 contacts the inclined surface and rotates, the base 32 drives the elastic reset wheel 34 to abut against the cylindrical body 24 and undergo elastic deformation, thereby guiding the guide post 104 to the bottom of the Y-shaped groove 351, so that the old brush roller 4a on the clamping roller mechanism 1 is aligned with the support 31 in the left and right directions.

[0073] like Figure 13 As shown, in order to ensure that the clamping roller mechanism 1 continues to slide down stably after being aligned with the support seat 31, guide support plates 105 are symmetrically arranged on the front and rear sides of the clamping roller mechanism 1. At the position close to the guide support plate 105, the base 32 is also provided with an elastic swing wheel 33. When the clamping roller mechanism 1 is aligned with the support seat 31, the guide support plate 105 contacts the elastic swing wheel 33, providing a stable sliding support point for the clamping roller mechanism 1 to move down, so that the clamping roller mechanism 1 can move smoothly to the designated position.

[0074] like Figure 11As shown, due to inherent errors in the equipment, this alignment is not absolute. Therefore, a guide assembly is needed to cooperate with the clamping roller mechanism 1 for guidance. The support 31 is aligned with the old brush roller 4a on the clamping roller mechanism 1 in the front-to-back direction by the drive of the roller telescopic member 322. The front and rear guide members are elastic swing wheels 33, which can be elastically deflected relative to the support 31. The clamping roller mechanism 1 is provided with a guide block 103 at the corresponding position. The guide block 103 is provided with a guide slope 104. When the clamping roller mechanism 1 carries the old brush roller 4a down to the support 31, the guide slope 104 and the elastic swing wheel 33 are pressed together, causing the elastic swing wheel 33 to rotate and be elastically deflected, thereby aligning the old brush roller 4a on the clamping roller mechanism 1 with the support 31 in the front-to-back direction.

[0075] Furthermore, such as Figure 23-25 As 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 block 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 block 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°.

[0076] like Figure 17As shown, in order to keep the traveling chassis 21 fixed during the unloading roller guidance and clamping roller guidance, 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 traveling 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 guidance and clamping roller guidance 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.

[0077] like Figure 18-27 As shown, the extended roller telescopic member 322 is in an unloaded exhaust state and no longer controls the sliding process of the support seat 31. This is because when the old brush roller 4a falls onto the support seat 31, the telescopic member 312 contacts the fixing mechanism and drives the support seat 31 to disengage to the right. If the roller telescopic member 323 still maintains the load control state when disengaging, it will inevitably generate unnecessary interference force on the support seat 31, which will have a negative impact on the unloading process.

[0078] like Figure 15 As shown, in order to prevent the clamping roller mechanism 1 from moving downwards and aligning with the left and right sides of the support seat 31, and thus to avoid misalignment between the clamping roller mechanism 1 and the support seat 31 during roller replacement, a limiting structure is provided between the base 3 and the clamping roller mechanism 1. The limiting structure includes a limiting block 106 and a top column 36. The limiting block 106 is located on the clamping roller mechanism 1, and the top column 36 is located on the base 32. When the clamping roller mechanism 1 controls the old brush roller 4a to align with the support seat 31 and place it on the support seat 31, the limiting block 106 and the top column 36 abut against each other. The area of ​​the end face of the block-shaped limiting block 106 that contacts the top column 36 is larger than the area of ​​the upper end face of the top column 36, so that the limiting block 106 and the top column 36 can fully contact each other and prevent the clamping roller mechanism 1 from moving downwards.

[0079] Based on the structural features of the novel floating roller seat in this embodiment, the floating support effect can be achieved through the cooperation of the clamping mechanism 1 and the roller seat during both unloading and clamping of the new roller. Therefore, based on the structure of the floating roller seat, an application of the floating roller seat is further provided, including:

[0080] S1: Pre-position a new roller; arrange two supporting mechanisms 3 side by side on the fixed mechanism 2, and set elastic support mechanisms 22 between the upper end of the fixed mechanism 2 and the lower ends of the two supporting mechanisms 3; then pre-position a new brush roller 4b on the rear supporting mechanism 3, and move the fixed mechanism 2 to the unloading position of the clamping roller mechanism 1; specifically, as Figure 12As shown, the support mechanism 3 is installed above the fixed mechanism 2, and the fixed mechanism 2 can drive the support mechanism 3 to move forward; the support seat 31 on the front support mechanism 3 is empty, and the support seat 31 on the rear support mechanism 3 is equipped with a new brush roller 4b; the left end of the empty support seat 31 is provided with a telescopic member 312, and the two telescopic members 312 are symmetrically arranged on the left end of the support seat 31. The telescopic members 312 can extend or retract in the left and right directions.

[0081] 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.

[0082] S2: Floating unloading roller; such as Figure 1-10 As shown, the clamping roller mechanism 1 clamps the old brush roller 4a and places the old brush roller 4a on the support mechanism 3, which further compresses the elastic support mechanism 22. The upper and lower ends of the elastic support mechanism 22 rotate, which at the same time drives the support mechanism 3 to deflect slightly along the horizontal plane, so that the old brush roller 4a floats on the support mechanism 3 first, and then gradually becomes stable on the support mechanism 3.

[0083] Specifically, the clamping roller mechanism 1 is controlled by a driving element and can slide and translate in the up, down, left, and right directions. The driving element (not shown) is usually a controlled hydraulic component. Its working principle can be referred to the specific structure of the lifting motor 135, the corner device 136, the connecting shaft 137, and the lifting mechanism 138 in the patent announcement number CN211103286, which will not be repeated here. The clamping roller mechanism 1 includes a stationary mechanism 102 and a sliding mechanism 101. An old brush roller 4a is axially fixed and circumferentially rotated between the stationary mechanism 102 and the sliding mechanism 101. The axis of the old brush 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 brush roller 4a on the clamping roller mechanism 1.

[0084] Furthermore, the stationary mechanism 102 and the sliding mechanism 101 are equivalent to the bearing seat of the old brush roller 4a. The left end of the bearing seat is the stationary mechanism 102, which 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 brush 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. 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 brush roller 4a, the left and right ends of the old brush roller 4a are clamped. When the sliding mechanism 101 slides to the right, the right end of the old brush roller 4a loses its support point for circumferential rotation, thereby causing the old brush roller 4a to disengage from the clamping mechanism 1.

[0085] like Figure 18-22 As shown, to make the floating support between the base 32 on the support mechanism 3 and the traveling chassis 21 more stable, at least two chains 231 are connected between the base 32 and the traveling chassis 21 of the support mechanism 3. The elastic support mechanism 22 generates an upward preload in the compressed state, and the chains 231 remain taut under the support elastic force generated by the elastic support mechanism 22. In the unloading step, when the old brush roller 4a is placed on the support 31, the disc spring in the elastic support mechanism 22 is compressed, and the chains 231 switch to the relaxed state. In the loading step, when the new brush roller 4b is removed from the support 31, the chains 231 switch back to the taut state. By judging the tension of the chains 231, it is possible to better determine whether the brush roller 4 is placed in place on the support 31.

[0086] Furthermore, such as Figure 22As shown, the tension and relaxation states of chain 321 are switched instantaneously under the condition of gravity change. Utilizing this characteristic, it can have a control function similar to a switching device; that is, at least one switching assembly 23 can be set on the traveling chassis of the fixed mechanism 2. The switching assembly 23 includes a rotating seat 232 and a switching element c. The switching element c is set on a bracket 235 next to the rotating seat 232. Among the chains 231 connecting the support chassis 32 of the supporting mechanism 3 and the traveling chassis 21 of the fixed mechanism 2, at least one chain 231 is hinged to the rotating seat 232 at its lower end. The rotating seat 232 is hinged to the mounting base 234 of the traveling chassis 21. The rotating seat 2323 has a forward-extending rotating piece 236. An elastic element 233 is provided between the rotating seat 232 and the fixed mechanism 2. The elastic element 233 can be hooked between the rotating seat 232 and the traveling chassis 2. The tension spring between 1 can also be a torsion spring hinged between the rotating seat 232 and the traveling chassis 21. During the unloading process, 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 101 slide to the right, so that the right end of the old brush roller 4a disengages from the sliding mechanism 101, and the remaining unloading operations are carried out successively. When loading the roller, the state of the chain 231 will only change after the new brush roller 4b is clamped and disengaged from the support seat 31. Therefore, although the support mechanism 3 for placing the new brush roller 4b at the rear is configured the same as the support mechanism 3 at the front, this is only to consider the universality between the support mechanisms 3. The chain 231 and the switching assembly 23 do not participate in the control of the sliding mechanism 101 again during the loading process.

[0087] Furthermore, in this invention, an unused new brush roller 4b is placed in advance on the rear support 31. The old brush roller 4a and the new brush roller 4b are the same size and specifications. When they are placed on the support 31, both ends of them are restricted from moving in the left and right directions by the corresponding fixing blocks 314 on the support 31. The only difference is that the old brush roller 4a is an old roller used in the steel plate brushing area s. The mechanisms for supporting the old brush roller 4a and the new brush roller 4b are the front empty support 31 and the rear support 31, respectively. The left side of the empty support 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... Extending or retracting in the left and right directions, the telescopic rod 313 is an auxiliary component for the left end of the old brush roller 4a to disengage from the stationary mechanism 102. On the support seat 31 on the rear side where the new brush roller 4b is installed, the telescopic component 313 does not participate in the roller installation process. Therefore, the rear support seat 31 may not need to be equipped with the telescopic component 31. However, in this embodiment, in order to ensure the versatility of the support mechanism 3 in the new support seat and for the convenience of maintenance and management of the support mechanism 3, the rear support seat 31 is configured the same as the front empty support seat 31. That is to say, in this embodiment, both the rear support seat 31 and the front empty support seat 31 can support the old brush roller 4a and the new brush roller 4b, and can work normally even if their positions are changed.

[0088] Furthermore, such as Figure 1-10 As shown, the sliding mechanism 101 in the roller clamping mechanism 1 is controlled by a control unit (not shown). When the old brush roller 4a is placed on the support 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 brush roller 4a. At this time, the left end of the old brush 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 brush 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 brush roller 4a to frequently connect and disconnect. In order to ensure good fit at the connection between the motor and the old brush 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 brush roller 4a, a telescopic member 312 is symmetrically arranged at the left end of the support 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 support 31. The support 31 will slide to the right along the guide rail 321, disconnecting the left end of the old brush roller 4a.

[0089] S3: Roller clamping reset; the fixing mechanism 2 moves forward to the roller loading position, the unloaded roller clamping mechanism 1 moves down to clamp the new brush roller 4b and disengage it from the supporting mechanism 3. At this time, the elastic support mechanism 22 resets and generates a supporting elastic force, causing the supporting mechanism 3 to return to a horizontal state; specifically, as Figure 7-8 As shown, the roller clamping process is to use the driving element to control the roller clamping mechanism 1 to move upward and move the fixing mechanism 2 forward, then control the roller clamping mechanism 1 to move downward to the left and right sides of the new brush 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 brush roller 4b are respectively locked into the sliding mechanism 101 and the stationary mechanism 102.

[0090] 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 support seat 31 with the old brush roller 4a mounted in front retracts. At the side of the telescopic rod 313, a detection element e is provided on the tube seat 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.

[0091] As shown in Figure 8, in step S3, before the clamping roller mechanism 1 completely leaves the support mechanism 3 while holding the new brush roller 4b, the clamping roller mechanism 1 slowly moves the new brush roller 4b upward. At this time, the compression of the elastic support mechanism 22 continues to decrease, and the released restoring force causes the support seat 31 of the support mechanism 3 to press against the new brush roller 4b upward, thereby forming a following support for the new brush roller 4b. In other words, the support seat 31, due to the upward release of the elastic force of the elastic support mechanism 22, will offset part of the weight of the new brush roller 4b, which plays an auxiliary role in the clamping roller mechanism 1 clamping the new roller 4b, making it easier for the clamping roller mechanism 1 to clamp the new brush roller 4b.

[0092] 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.
