Abstract

This invention provides a configuration and usage method for an instantaneous sensing mechanism. By arranging a chain sensing module on the receiving roller module and utilizing the characteristic of the chain being taut when stressed and loose when unstressed, the chain sensing module can quickly sense and respond to gravity change signals on the receiving roller unit. This gravity change signal is then converted into a rotational motion signal via the chain, allowing timely feedback on changes in external force on the receiving roller unit. This rapidly triggers the sensing element, enabling the brush roller to be placed on the receiving roller unit and immediately begin the roller removal operation. This simplifies the brush roller replacement process and improves roller replacement efficiency.

Description

Technical Field

[0001] This invention relates to the field of metal surface treatment, and in particular to the configuration and usage method of an instantaneous sensing mechanism. 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 plates has emerged. This equipment uses brush rollers to physically grind the surface of the steel plates, improving the rust removal efficiency. This equipment is widely accepted due to its low efficiency and low pollution. However, during grinding, the brush roller needs to come into contact with the steel plate surface. After prolonged use, the grinding effect of the brush roller will decrease. Therefore, the brush roller needs to be placed on the roller changing trolley before being replaced with a new roller. When replacing the brush roller, the brush roller is usually held by the clamping mechanism on the rust removal machine. Then, the new roller is placed on the roller receiving unit of the roller changing trolley. After confirming that the brush roller is in place, a command is sent to the clamping mechanism to detach the brush roller from both ends of the clamping mechanism. However, determining whether the brush roller is in place on the roller receiving unit has become a problem that has troubled people.

[0003] For example, in the roller changing device patent with publication number CN216371699, such as in the patent... Figures 1-12 As shown, the roller receiving seat supporting the brush roller can move forward or backward on the guide rail along the length of the roller receiving seat under the drive of the roller changing drive assembly. However, since the roller receiving seat only serves to receive the brush roller, it is impossible to determine whether the brush roller is placed in place on the roller receiving seat. Therefore, when the brush roller falls onto the roller receiving seat, it is only possible to rely on visual observation or listening to the collision sound between the brush roller and the roller receiving unit to confirm that the brush roller and the roller receiving unit are roughly in contact before starting the roller removal operation. This method is time-consuming and laborious, and may also damage the brush roller or the roller receiving unit. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a configuration and usage method for an instantaneous sensing mechanism. By arranging a chain sensing module on the receiving roller module and utilizing the characteristic of the chain being taut when stressed and slack when unstressed, the chain sensing module can quickly sense and respond to gravity change signals on the receiving roller unit. This gravity change signal is then converted into a rotational motion signal via the chain, allowing timely feedback on changes in external force on the receiving roller unit. This rapidly triggers the sensing element, enabling the brush roller to be placed on the receiving roller unit and immediately begin the roller removal operation. This simplifies the brush roller replacement process and improves roller replacement efficiency.

[0005] The technical solution of this invention is implemented as follows: A method for configuring and using an instantaneous sensing mechanism, comprising: S1: Pre-set roller receiving module; The roller receiving module includes a fixed unit and a roller receiving unit. The roller receiving unit is positioned above the fixed unit. A compressed elastic component is provided between the roller receiving unit and the fixed unit. The elastic component then generates an upward supporting elastic force on the roller receiving unit. S2: Pre-set chain sensing module; the chain sensing module includes a mounting base and a sensing component, the sensing component includes a transmission base and a sensing element; the sensing element can receive the action signal of the transmission base rotating; one end of the transmission base is connected to a chain, the other end is hinged to the mounting base, and an elastic element is provided between the transmission base and the mounting base; S3: Preset clamping roller module; the clamping roller module holds the brush roller and can move freely; the clamping roller module can receive instructions from the sensing element to disengage the brush roller from the clamping roller module; S4: Module installation; Arrange the chain sensing module between the fixed unit and the roller receiving unit, and connect the mounting base and chain in the chain sensing module to the top of the fixed unit and the bottom of the roller receiving unit respectively, so that the chain is taut under the action of the supporting elastic force and drives the transmission seat to rotate upward, thereby causing the elastic component to undergo elastic deformation; S5: Component trigger; the clamping roller module clamps the brush roller and moves it to the top of the receiving roller unit for alignment, then moves it down to place the brush roller in the middle position of the receiving roller unit, causing the elastic component to be continuously compressed. At this time, the chain is instantly relaxed, causing the elastic component to release its deformation elastic force, driving the transmission seat to rotate downwards, and triggering the sensing element to send a command to the clamping roller module, causing the brush roller to disengage from the clamping roller module.

[0006] Preferably, the elastic element is a tension spring, with its two ends connected to the mounting base and the transmission base respectively. In step S4, when the transmission base rotates upward, the elastic element undergoes elastic tensile deformation, thereby storing tensile elastic force for the transmission base to rotate in the opposite direction.

[0007] Preferably, the elastic element is a torsion spring concentrically hinged to the transmission seat, with the torsion arms at both ends of the torsion spring hooked onto the mounting seat and the transmission seat respectively; in step S4, the transmission seat rotates upward, causing the elastic element to undergo elastic torsional deformation; thereby storing torsional elastic force for the transmission seat to rotate in the opposite direction.

[0008] Preferably, the clamping roller module includes a stationary unit and a moving unit. The moving unit can slide along the brush roller axis to allow the brush roller to be positioned or disengaged on the clamping roller module. In step S5, the sensing element sends a sliding command to the moving unit to move the moving unit away from the brush roller shaft end, thereby disengaging the brush roller from the clamping roller module. The timing of the disengagement operation can be precisely controlled by using the control command of the sensing element.

[0009] Preferably, in step S4, the mounting base and chain in the chain-type sensing module are fixed to the fixing unit and the receiving roller unit respectively by means of threaded connection; so that the chain-type sensing mechanism can be easily disassembled and assembled on the roller changing module.

[0010] Preferably, in step S4, at least two chain sensing modules are symmetrically arranged between the fixed unit and the receiving roller unit; in step S5, when all the sensing elements in all the chain sensing modules are triggered, the sensing elements will send a command to the clamping roller module to disengage the brush roller from the clamping roller module; thus, the response of the sensing elements can be used to determine whether the brush roller is in the middle position on the receiving roller unit.

[0011] Preferably, the elastic components are symmetrically arranged between the fixed unit and the receiving roller unit, and the upper and lower ends of the elastic components are respectively hinged to the lower part of the receiving roller unit and the upper part of the fixed unit. In step S5, when the elastic components are continuously compressed, the upper and lower ends of the elastic components rotate, which drives the receiving roller unit and the brush roller to rotate horizontally. If the brush roller is not positioned correctly, the elastic component on one side will be subjected to excessive force. The hinge design can make the elastic component adapt to the position of the brush roller, avoiding damage to the elastic component due to excessive force.

[0012] Preferably, a symmetrical torsional support unit is provided between the fixing unit and the receiving roller unit. The torsional support unit includes a column and an elastic wheel, with the elastic wheel connected to the lower end of the receiving roller unit. On the outer wall of the column 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 column, there are corresponding elastic wheels abutting against it. In step S5, when the receiving roller unit and the brush roller undergo horizontal torsion, the corresponding elastic wheel presses against the outer wall of the column, thereby generating a torsional support elastic force on the receiving roller unit, restoring the receiving roller unit and the brush roller to a horizontal state. This protects the elastic component and keeps the brush roller and the receiving roller unit in a horizontal state, preventing the receiving roller module from tipping over.

[0013] Preferably, the receiving roller unit includes a base and a receiving roller seat disposed above the base. The base is provided with a center telescopic component, which is connected to the lower part of the receiving roller seat. The center telescopic component can extend and retract in the left and right direction, causing the receiving roller seat to slide left and right relative to the base. In step S1, the center telescopic component extends or retracts, causing the receiving roller seat to slide to the middle position of the base. This ensures that the receiving roller seat on the receiving roller unit is in a centered state, preventing the center of gravity of the receiving roller module from shifting when receiving the brush roller.

[0014] Preferably, the upper end of the base is symmetrically provided with guide rollers extending in the left and right directions, and the receiving roller seat roller is provided with a guide groove below it; in step S5, when the receiving roller unit and the brush roller are horizontally twisted, and the elastic wheel in the corresponding direction is pressed against the outer wall of the column, the guide groove cooperates with the guide roller, so that the receiving roller seat roller slides relative to the base in the left and right directions and returns to the middle position of the base; thereby, all the sensing components can be triggered at the middle position of the receiving roller unit, so that the sensing element can smoothly send the roller removal command to the moving unit.

[0015] The principle of the present invention, which adopts the above technical solution, is as follows: This invention provides a configuration and usage method for an instantaneous sensing mechanism. By arranging a chain sensing module on a roller receiving module and utilizing the characteristics of the chain being taut when stressed and loose when stressed, the chain sensing module can quickly sense and respond to gravity change signals on the roller receiving unit. The gravity change signal is then converted into a rotational motion signal through the chain, allowing timely feedback on changes in external force on the roller receiving unit, thereby rapidly triggering the sensing element.

[0016] The beneficial effects of the present invention, which adopts the above technical solution, are as follows: This method can accurately transmit the gravity change signal of the brush roller on the receiving roller module to the clamping roller module through the transmission of the chain sensing module, thereby determining the timing of roller removal. Compared with using manual control of the roller removal process, this method is simpler to operate and improves the roller removal efficiency.

[0017] 2. This method relies on the chain sensing module to detect or transmit signals about the change in gravity of the brush roller on the receiving roller module. Compared with visual inspection or sound inspection, this method avoids collisions between the brush roller and the receiving roller module, thus protecting them from damage caused by mutual impact.

Implementation

[0019] 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.

[0020] The specific embodiments of the present invention are as follows: like Figure 1-29 As shown, this embodiment provides a method for configuring and using an instantaneous sensing mechanism. This method is typically used during the replacement of brush roller 4, which includes an old brush roller 4a and a new brush roller 4b, both of the same size and specifications. In this embodiment, the process of receiving the old brush roller 4a during the replacement of brush roller 4 will be used for illustration. The method includes: S1: Pre-set roller receiving module; The roller receiving module includes a fixed unit 2 and a roller receiving unit 3. The roller receiving unit 3 is positioned above the fixed unit 2. A compressed elastic component 22 is provided between the roller receiving unit 3 and the fixed unit 2. To ensure stable support of the roller receiving unit 3, the elastic component 22 is symmetrically arranged between the roller receiving unit 3 and the fixed unit 2. The compressed elastic component 22 will generate an upward supporting elastic force on the roller receiving unit 3. Specifically, the roller receiving unit 3 includes a base 32 and a roller receiving seat 31 positioned above the base 32. A center telescopic component 322 is provided on the base 32. The center telescopic component 322 is connected to the lower part of the roller receiving seat 31. The center telescopic component 322 can extend and retract in the left and right direction, causing the roller receiving seat 31 to slide left and right relative to the base 32. Typically, a cylinder is used. The central telescopic component 322 is equipped with a sliding rod 323, which can extend or retract in the left and right directions. The central telescopic component 322 is connected to the T-shaped connecting sleeve 315 provided below the roller receiving seat 31 through the T-shaped head of the sliding rod 313, so that the position of the roller receiving seat 31 is controlled by the central telescopic component 323. A stroke limiting seat 317 is provided at the corresponding position below the roller receiving seat 31. When the central telescopic component 322 extends, it drives the roller receiving seat 31 to slide in the left and right directions. The cylinder bottom of the central telescopic component 322 abuts against the stroke limiting seat 317 to limit the movement, so that the roller receiving seat 31 slides to the middle position of the base 32, so that the old brush roller 4a can accurately fall on the middle position of the roller receiving seat 31, avoiding the center of gravity of the roller receiving module 3 from shifting when receiving the old brush roller 4a.

[0021] like Figure 17-21 As shown, the fixed unit 2 remains fixed in the vertical direction and can move freely relative to the ground in the front-back direction. The fixed unit 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 fixed unit 2 on the slide rail a. In order to keep the direction of the fixed unit 2 of the new roller seat unchanged during movement, a slide rail a is also provided on the ground. The slide rail a separates the new roller seat from the ground, so that the fixed unit 2 can move forward more smoothly on the slide rail a without worrying about the new roller seat deflecting.

[0022] Specifically, both the base 32 and the fixing unit 2 are equipped with hinge seats 221. The elastic component 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 walking chassis 21 are connected by a support rod 227. An elastic element 222 is sleeved on the outer wall of the support rod 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, stacked and close together, are held tightly between the support block 228 and the support rod 227 by the gravity of the receiving roller unit 3. This generates an upward preload on the support block 228, providing stable support for the base 32 and the receiving roller seat 31. When the old brush roller 4a is placed on the receiving roller 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, creating a buffering and shock-absorbing effect in the vertical direction and along the axis of the old brush roller 4a. This reduces the impact of the old brush roller 4a on the receiving roller unit 3, ensuring that the old brush roller 4a will not jump when it is removed.

[0023] like Figure 21 As 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 and make the operation of the elastic support cylinder smoother.

[0024] S2: Pre-installed chain sensing module; the chain sensing module includes a mounting base 234 and a sensing component, the sensing component includes a transmission base 232 and a sensing element c; the sensing element c can receive the action signal of the transmission base 232 rotating; one end of the transmission base 232 is connected to a chain 231, the other end is hinged to the mounting base 234, and an elastic element 233 is provided between the transmission base 232 and the mounting base 234; Specifically, the chain 231 is made of at least two metal rings connected in series; the chain made of metal rings has sufficient structural strength, and this chain structure design can switch from a taut state to a relaxed state relatively quickly, so that the transmission seat 232 can transmit the action signal to the sensing element c more quickly.

[0025] Furthermore, in order to prevent the spring element 233 from disengaging due to excessive rotation of the transmission seat 232, after the transmission seat 232 rotates in the opposite direction and triggers the sensing element c, the transmission seat 232 abuts against the bottom of the mounting seat 234, restricting the transmission seat 232 from continuing to rotate.

[0026] Furthermore, during the rotation of the transmission seat 232, in order to enhance the transmission effect of the transmission seat 232, a rotating plate 236 is fixed at one end of the transmission seat 232 near the sensing element c. The design of the rotating plate 236 makes the torque arm of the transmission seat 232 longer. When the transmission seat 232 drives the rotating plate 236 to rotate in the opposite direction, the rotation action signal of the transmission seat 232 can be amplified and fed back to the sensing element c. In order to maintain the stability of the sensing element c, a fixed bracket 235 is provided on the side of the mounting base 234, and the sensing element c is set above the bracket 235.

[0027] S3: Preset clamping roller module 1; the clamping roller module 1 holds the brush roller 4 and can move freely; the clamping roller module 1 can receive instructions from the sensing element c to disengage the brush roller 4 from the clamping roller module 1; specifically, the clamping roller module 1 includes a stationary unit 102 and a moving unit 101. The moving unit 101 can slide along the axial direction of the brush roller 4 to make the brush roller 4 enter or disengage from the clamping roller module 1. The sliding timing of the moving unit 101 is controlled by the sensing element c. When the sensing element c sends a sliding instruction to the moving unit 101, the moving unit 101 will slide away from the end of the brush roller 4 to disengage the brush roller 4 from the clamping roller module 1.

[0028] Specifically, the clamping roller module 1 is controlled by a drive element and can slide horizontally in the up, down, left, and right directions. The drive 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 module 1 includes a moving unit 102 and a sliding mechanism 101. An old brush roller 4a is axially fixed and circumferentially rotating between the moving unit 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 module 1.

[0029] Furthermore, the moving unit 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 moving unit 102, and a motor is connected to the left end of the moving unit 102. The motor drives the components in the stationary unit, allowing the old brush roller 4a to 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 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 the cylinder. It is controlled by a control unit (not shown), such as a master controller. Only when the sensing element c sends a command to the control unit will the oil cylinder or air 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 roller module 1.

[0030] S4: Module installation; The chain sensing module 23 is arranged between the fixed unit 2 and the roller receiving unit 3, and the mounting base 234 and chain 231 in the chain sensing module are respectively connected to the upper part of the fixed unit 2 and the lower part of the roller receiving unit 3. The fixing method is a threaded connection, so that the chain sensing module 23 can be easily disassembled, installed and repaired on the roller receiving module 1.

[0031] Specifically, such as Figure 17-27 As shown, since the chain sensing module 23 can only detect the change in gravity at one location, in order to confirm that the old brush roller 4a has not deviated from the center of gravity position on the receiving roller unit 3, at least two chain sensing modules 23 are symmetrically arranged between the fixed unit 2 and the receiving roller unit 3. Only when the old brush roller 4a is placed in the middle position of the receiving roller unit 3 will the entire center of gravity of the receiving roller unit 3 not shift significantly. In other words, only when all the chain sensing modules 23 are triggered can it be proven that the old brush roller 4a has not deviated from the predetermined drop position.

[0032] Furthermore, the reason why the elastic component 22 is in a compressed state is to ensure that it can generate an upward supporting elastic force on the receiving roller unit 3. The chain 231 is tightened under the action of the supporting elastic force and drives the transmission seat 232 to rotate upward, thereby causing the elastic component 233 to undergo elastic deformation. At the same time, in order to keep the supporting elastic force from existing, the chain 231, which is on the fixed unit 2 and is taut, is also pulling the receiving roller unit 3 to prevent the receiving roller unit 3 from resetting upward under the action of the supporting elastic force.

[0033] Furthermore, the function of the elastic element 233 is to provide sufficient rotational elastic force when the chain 231 is momentarily relaxed. Therefore, the elastic element 233 can be either a tension spring or a torsion spring. When the elastic element 233 is a tension spring, its two ends are connected to the mounting base 234 and the transmission base 232, respectively. When the chain 231 is momentarily relaxed, the transmission base 232 rotates upward, and the elastic element 233 undergoes elastic tensile deformation, thereby storing tensile elastic force for the reverse rotation of the transmission base. When the elastic element 233 is a torsion spring, it is concentrically hinged to the transmission base 232, and the torsion arms at both ends of the torsion spring are hooked onto the mounting base 234 and the transmission base 232, respectively. When the chain 231 is momentarily relaxed, the transmission base 232 rotates upward, causing the elastic element 233 to undergo elastic torsional deformation, thereby storing torsional elastic force for the reverse rotation of the transmission base.

[0034] S5: Trigger; The clamping roller module 1 clamps the brush roller 4 and moves it to the top of the receiving roller unit 3 for alignment, then moves it down to place the brush roller 4 in the middle position of the receiving roller unit 3, so that the elastic component 22 is continuously compressed. At this time, the chain 231 is instantly relaxed. At this time, the elastic components 233 in all chain sensing modules 23 release the deformation elastic force, drive the transmission seat 232 to rotate downward, and trigger the sensing element c to send a command to the clamping roller module 1, so that the brush roller 4 is disengaged from the clamping roller module 1.

[0035] Specifically, such as Figure 17-28As shown, the elastic component 22 is symmetrically arranged between the fixed unit 2 and the receiving roller unit 3, providing stable elastic support for all positions of the receiving roller unit 3. However, due to the inherent equipment error and the relatively large mass and volume of the old brush roller 4a, when the old brush roller 4a is not centered on the receiving roller unit, the entire receiving roller unit 3 will deflect to one side. If the elastic component 22 is simply fixed between the fixed unit 2 and the receiving roller unit 3, the elastic component 22 at the deflection position will be easily subjected to a huge torsional force. Prolonged exposure to such a force will cause excessive deformation of the entire elastic component 22, leading to its damage. Therefore, the upper and lower ends of the elastic component 22 are hinged to the lower part of the receiving roller unit 3 and the upper part of the fixed unit 2, respectively. When the old brush roller 4a and the receiving roller unit 3 deflect, the elastic component 22 is continuously compressed, causing the upper and lower ends of the elastic component 22 to rotate. This causes the receiving roller unit 3 and brush roller 4 to rotate horizontally. At this time, the elastic component 22 distributes the torsional force to the horizontal direction through hinge. In order to prevent the receiving roller unit 3 from tipping over, a left-right symmetrical torsion support unit is provided between the fixed unit 2 and the receiving roller unit 3. The torsion support unit includes a column 24 and an elastic wheel 34. The elastic wheel 34 is connected to the lower end of the receiving roller unit 3. On 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 wheels 34 that abut against it. When the receiving roller unit 3 and brush roller 4 rotate horizontally, the elastic wheel 34 in the corresponding direction is pressed against the outer wall surface of the column 24, thereby generating a torsional support elastic force on the receiving roller unit 3. The torsional support elastic force can be used to counteract the deflection force that would cause the receiving roller unit 3 to tip over, so that the receiving roller unit 3 and brush roller 4 return to a horizontal state.

[0036] Furthermore, such as Figure 16 As shown, the 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. In addition to providing a reverse support elastic force for the base 32, the elastic wheel 34 can also use the good rebound elasticity of the mold spring or disc spring to generate an 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 assembly 22.

[0037] Furthermore, the old brush roller 4a on the roller receiving unit 3, which has been restored to a horizontal state, must return to the middle position in order to trigger all the chain sensing modules 23. Therefore, guide rails 321 extending in the left and right directions are symmetrically provided on the upper end of the base 32, and guide grooves 316 are provided below the roller receiving seat 31. When the roller receiving unit 3 and the brush roller 4 are horizontally twisted, and the elastic wheel 34 in the corresponding direction is pressed against the outer wall of the column 24, the guide groove 316 cooperates with the guide rail 321 to make the roller receiving seat 31 slide in the left and right directions relative to the base 32 and return to the middle position of the base 32.

[0038] like Figure 13 As shown, in order to ensure that the clamping roller module 1 continues to slide down stably after being aligned with the receiving roller seat 31, guide support plates 105 are symmetrically arranged on the front and rear sides of the clamping roller module 1. At the position close to the guide support plate 105, the base 32 is also correspondingly provided with an elastic swing wheel 33. When the clamping roller module 1 is aligned with the receiving roller seat 31, the guide support plate 105 contacts the elastic swing wheel 33, providing a stable sliding support point for the clamping roller module 1 to move down, so that the clamping roller module 1 can move smoothly to the designated position.

[0039] like Figure 11 As shown, due to inherent errors in the equipment, this alignment is not absolute. Therefore, a guide assembly is required to cooperate with the clamping roller module 1 for guidance. The front and rear guide components are elastic swing wheels 33, which can elastically deflect back and forth relative to the receiving roller seat 31. The clamping roller module 1 is provided with a guide block 103 at the corresponding position, and the guide block 103 is provided with a guide slope 104. When the clamping roller module 1 carries the old brush roller 4a down to the receiving roller seat 31, the guide slope 104 and the elastic swing wheel 33 are pressed together, causing the elastic swing wheel 33 to rotate and elastically deflect, thereby aligning the old brush roller 4a on the clamping roller module 1 with the receiving roller seat 31.

[0040] like Figure 11 As shown, the guiding effect of the clamping roller module 1 and the receiving roller unit 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 seats 35, thus forming two symmetrical inclined surfaces on the guide seats 35. The clamping roller module 1 is provided with a circumferentially rotatable guide post 104 at the corresponding position. When the clamping roller module 1 carries the old brush roller 4a down to the receiving roller seat 31, the guide post 104 contacts the inclined surface and rotates. The squeezing force will cause the receiving roller seat 31 to slide in the left and right directions. In order to make the sliding process smoother, a guide groove 316 is provided below the receiving roller seat 31, and a guide rail 321 extending in the left and right directions is provided on the base 32. When the guide post 104 contacts the inclined surface and rotates, the elastic wheel 34 undergoes 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 module 1 is aligned with the receiving roller seat 31 in the left and right directions.

[0041] 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 module 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 typically made of rubber with good resilience. To enable the guide wheel 331 to rotate and generate elastic compression when squeezed by the fixed unit 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°.

[0042] like Figure 17 As 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 fixed unit 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 fixed unit 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 fixed unit 2 needs to stop, the head of the positioning telescopic rod 212 is inserted into the V-shaped groove, so that the fixed unit 2 remains fixed front and back.

[0043] Furthermore, the positioning telescopic component 211 is controlled by the receiving unit (not shown). The receiving unit can be a sub-controller. When the fixed unit 2 needs to slide to load the roller, the telescopic rod 313 of the telescopic component 312 on the roller receiving seat 31, which is equipped with the old brush roller 4a, 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 fixed unit 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 allowing the fixed unit 2 to move forward.

[0044] like Figure 18-27 As shown, the extended telescopic member 322 is in an unloaded exhaust state and no longer controls the sliding process of the roller receiving seat 31. This is because when the old brush roller 4a falls onto the roller receiving seat 31, the telescopic member 312 contacts the fixed unit and drives the roller receiving seat 31 to the right to disengage. If the telescopic member 323 still maintains the load control state when disengaging, it will inevitably generate unnecessary interference force on the roller receiving seat 31, which will have a negative impact on the unloading process.

[0045] like Figure 15 As shown, in order to prevent the clamping roller module 1 from moving downwards and aligning with the left and right sides of the receiving roller seat 31, thus avoiding misalignment between the clamping roller module 1 and the receiving roller seat 31 during roller replacement, a limiting structure is provided between the base 3 and the clamping roller module 1. The limiting structure includes a limiting block 106 and a top post 36. The limiting block 106 is located on the clamping roller module 1, and the top post 36 is located on the base 32. When the clamping roller module 1 controls the old brush roller 4a to align with the receiving roller seat 31 and places it on the receiving roller seat 31, the limiting block 106 and the top post 36 abut against each other. The area of ​​the end face of the block-shaped limiting block 106 that contacts the top post 36 is larger than the area of ​​the upper end face of the top post 36, so that the limiting block 106 and the top post 36 can fully contact each other and prevent the clamping roller module 1 from moving downwards.

[0046] like Figure 27 As shown, in order to make it easier for the old brush roller 4a to be removed from the clamping roller module 1, a telescopic component 312 is provided at the left end of the roller receiving seat 31. Two telescopic components 312 are symmetrically arranged at the left end of the roller receiving seat 31. The telescopic component 312 can extend or retract in the left and right directions. In order to keep the telescopic component 312 stable and not shake when it extends, a protective tube seat 311 is provided below the telescopic component 312. The protective tube seat 311 is 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 tube seat 312. The lower part of the extended end of the telescopic component 312 is fixed on the support plate so that the telescopic component 312 can be stably supported when it extends.

[0047] Furthermore, such as Figure 1-10As shown, the sliding mechanism 101 in the clamping roller module 1 is controlled by a control unit (not shown). When the old brush roller 4a is placed on the receiving roller 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 brush roller 4a. At this time, the left end of the old brush roller 4a is still connected to the moving unit 102. The reason for not setting a sliding mechanism 101 on the left end of the clamping roller module 1 is that the moving unit 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 clamping roller module 1, setting the left end of the clamping roller module 1 as a sliding mechanism would make the axial structure of the clamping roller module 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 component 312 is symmetrically set at the left end of the roller receiving seat 31. The telescopic rod 313 inside the telescopic component 312 extends out and abuts against the vertical plate at the end of the fixed unit 101. At this time, the clamping roller module 1 is in a stationary state. After being abutted by the telescopic rod 313, it will generate a reaction force on the roller receiving seat 31. The roller receiving seat 31 will slide to the right along the guide rail 321, disconnecting the left end of the old brush roller 4a.

[0048] Furthermore, in this invention, an unused new brush roller 4b is placed in advance on the rear receiving roller seat 31. The old brush roller 4a and the new brush roller 4b are the same size and specifications. When they are placed on the receiving roller seat 31, both ends of them are restricted from moving in the left and right directions by the corresponding fixing blocks 314 on the receiving roller seat 31. The only difference is that the old brush roller 4a is an old roller used in the steel plate brushing area s, and the mechanisms for receiving the old brush roller 4a and the new brush roller 4b are the front empty receiving roller seat 31 and the rear receiving roller seat 31, respectively. The left side of the empty receiving roller 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... 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 detach from the moving unit 102. On the roller receiving seat 31 with the new brush roller 4b installed at the rear, the telescopic component 313 does not participate in the roller installation process. Therefore, the rear roller receiving seat 31 may not be equipped with the telescopic component 31. However, in this embodiment, in order to ensure the universality of the roller receiving unit 2 in the new roller receiving seat and for the convenience of maintenance and management of the roller receiving unit 2, the rear roller receiving seat 31 is configured the same as the front empty roller receiving seat 31. That is to say, in this embodiment, both the rear roller receiving seat 31 and the front empty roller receiving seat 31 can receive the old brush roller 4a and the new brush roller 4b, and can work normally even if their positions are changed.

[0049] like Figure 7-8As shown, after the old brush roller 4a is removed, the clamping process of the new brush roller 4a is to use the driving element to control the clamping module 1 to move upward and the fixed unit 2 to move forward, and then control the clamping module 1 to move down to the left and right sides of the new brush roller 4b. After that, 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 moving unit 102. At this time, the chain sensing module 23 does not participate in the clamping process.
