An elastic guide mechanism

Abstract

This invention provides an elastic guiding mechanism, including guide plates and an elastic deflection mechanism respectively disposed on an active mechanism and a driven mechanism. The elastic deflection mechanism is provided with a guide wheel, which can generate elastic deflection on the elastic deflection mechanism. The guide plate is provided with a first guiding inclined surface. When the active mechanism and the driven mechanism cooperate, the first guiding inclined surface and the annular outer wall surface of the guide wheel are pressed to generate a horizontal force. At this time, the guide wheel rotates and undergoes elastic deflection on the elastic deflection mechanism, thereby gradually transmitting the generated horizontal force to the driven mechanism, causing the driven mechanism to move to a position aligned with the active mechanism. The horizontal force is generated by the pressing cooperation between the guide wheel on the elastic swing mechanism and the guide plate. At the same time, the horizontal force is gradually transmitted to the driven mechanism through the rotation and elastic deflection process of the guide wheel, enabling the driven mechanism to align with the active mechanism, avoiding collisions between the components of the active mechanism and the driven mechanism, and improving the service life of the guide wheel.

Description

Technical Field

[0001] This invention relates to the field of metal surface treatment, and in particular to an elastic guiding 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. To remove the rust layer, existing environmental protection equipment uses grinding equipment to remove rust by brushing the surface of the steel plates. This equipment improves the rust removal efficiency and reduces pollution by physically grinding the surface of the steel plates with brush rollers. However, this equipment requires the brush rollers to contact the surface of the steel plates during grinding. After prolonged use, the grinding effect of the brush rollers will decrease. Therefore, the brush rollers need to be placed on a roller replacement cart for replacement with new rollers. During the brush roller replacement process, the steel plates need to be ground. The clamping mechanism on the equipment lowers the old brush roller and places it on the roller seat of the roller changing trolley. However, due to equipment errors, the clamping mechanism and the roller changing trolley cannot be perfectly aligned during the roller changing operation. Therefore, although the roller changing process can proceed normally most of the time, there is always a slight deviation in the alignment position, which often causes the brush roller to collide with the roller changing trolley components during the roller changing process. If the deviation is large, it may also cause the brush roller to fall off and roll on the roller changing trolley. The existing improvement solution is to design guide wheels on the roller changing trolley that receives the brush roller. The guide wheels are made of flexible material. When the brush roller falls off the correct position, the end of the brush roller is squeezed against the guide wheel. The deformation of the guide wheel itself absorbs the impact force of the brush roller on the roller changing trolley. However, this design has defects.

[0003] For example, in the patent for a roller changing device published in CN216371699, such as the one in the patent... Figure 10 As shown, a support component, namely a rotatable guide wheel, is installed above the roller changing device. During the process of supporting the brush roller, even if the center position of the brush roller is not exactly in the middle of the two guide wheels, the guide wheels can still guide the brush roller to roll back to the center position of the roller seat. Although this can reduce the impact of the brush roller on the roller changing carriage, when the brush roller contacts the guide wheel, since the guide wheel itself does not have a corresponding buffer structure, it can only absorb the impact force of the collision between the brush roller and the guide wheel through the deformation of its own material. After absorbing the impact multiple times, the guide wheel will inevitably experience surface wear and structural deformation. If the guide wheel is frequently replaced, it will affect the accuracy positioning of the roller changing device. Therefore, although this guiding method avoids rigid collision between the brush roller and the roller changing carriage, it cannot guarantee the structural strength of the roller seat and will also reduce the service life of the guide wheel during the guiding process. Its guiding effect is not ideal and cannot meet the guiding requirements in the roller changing process. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide an elastic guiding mechanism. This mechanism generates a horizontal force through the pressing and engaging between the guide wheel and the guide plate on the elastic swing mechanism. Simultaneously, the horizontal force is gradually transmitted to the driven mechanism through the rotation and elastic deflection of the guide wheel. This enables the driven mechanism to align with the driving mechanism, avoiding collisions between components on the driving and driven mechanisms and extending the service life of the guide wheel.

[0005] The technical solution of this invention is implemented as follows:

[0006] An elastic guiding mechanism is provided, which is symmetrically arranged in the front-back direction between an active mechanism and a driven mechanism that can cooperate with each other. The elastic guiding mechanism includes a guide plate and an elastic deflection mechanism respectively disposed on the active mechanism and the driven mechanism. The elastic deflection mechanism is provided with a circumferentially rotatable guide wheel. The guide wheel can generate elastic deflection on the elastic deflection mechanism under the compression of radial external force. The guide plate is provided with a first guiding inclined surface. When the active mechanism and the driven mechanism cooperate, the first guiding inclined surface is compressed against the annular outer wall surface of the guide wheel to generate a horizontal force. At this time, the guide wheel rotates and undergoes elastic deflection on the elastic deflection mechanism, thereby gradually transmitting the generated horizontal force to the driven mechanism, causing the driven mechanism to move to a position aligned with the active mechanism.

[0007] Preferably, the elastic deflection mechanism further includes a base and a swing arm. The guide wheel is hinged to the swing arm, and the swing arm is hinged to the base. An elastic telescopic member is provided between the swing arm and the base to provide elastic force for the elastic deflection of the guide wheel. The swing arm and the elastic telescopic member convert the deformation process of the guide wheel into the elastic deflection process of the swing arm, avoiding the damage caused by excessive deformation of the guide wheel when it is under force.

[0008] Preferably, when the guide wheel is not subjected to radial external force, the elastic telescopic member is in a compressed state between the swing arm and the base; the compressed elastic telescopic member will generate an elastic preload between the swing arm and the base, making the elastic swing effect of the elastic swing mechanism better.

[0009] Preferably, when the guide wheel is subjected to radial external force, the elastic telescopic component is further compressed, causing the guide wheel to undergo elastic deflection on the elastic deflection mechanism; the elastic force generated by further compression will gradually increase, so as to better adapt to the squeezing and matching effect between the guide plate and the guide wheel.

[0010] Preferably, the elastic guiding mechanism further includes reset supports symmetrically arranged on the active mechanism. The reset supports are arranged on opposite sides of the guide plate in the left-right direction. The corresponding position on the driven mechanism is also provided with an elastic deflection mechanism that interacts with the reset supports. When the first guide inclined surface is pressed against the annular outer wall of the guide wheel, the driven mechanism deflects on the horizontal plane. The reset supports can press against the guide wheel on the corresponding elastic deflection mechanism to generate a reset force, causing the driven mechanism to rotate in the opposite direction and return to the center. The cooperation between the guide plate and the elastic swing mechanism can determine the deviation distance between the positions of the active mechanism and the driven mechanism through the deflection distance of the driven mechanism. The reset supports can interact with the elastic swing mechanism to generate a return force on the driven mechanism, so that the driven mechanism moves back to the center while automatically correcting the deviation distance along the deviation direction and aligning with the active mechanism again.

[0011] Preferably, the reset support is a strip support plate symmetrically arranged on the active mechanism, and the thickness of the strip support plate is less than the thickness of the guide plate. When the first guide inclined surface is pressed against the annular outer wall of the guide wheel, the driven mechanism deflects on the horizontal plane, and the deflection distance of the driven mechanism is less than or equal to the thickness difference between the strip support plate and the guide plate. The thickness difference provides a deflection space margin for the driven mechanism to offset, so as to facilitate the measurement of the deviation distance between the active mechanism and the driven mechanism.

[0012] Preferably, the thickness difference between the guide plate and the strip support plate is between 1mm and 10mm.

[0013] Preferably, after the driven mechanism rotates in the opposite direction and returns to the center, the support plate and guide plate on the driving mechanism simultaneously compress the guide wheel on the elastic deflection mechanism at the corresponding position on the driven mechanism, thereby forming four cooperating support points between the driving mechanism and the driven mechanism; the four cooperating support points can provide stable support for the driving mechanism and the driven mechanism, so that the driving mechanism and the driven mechanism can cooperate smoothly.

[0014] Preferably, the outer plane above the first guide slope on the guide plate contracts downward and inward, thus forming a second guide slope on the outer plane of the guide plate. When the guide wheel rolls over the first guide slope, it will squeeze and cooperate with the second guide slope to generate a horizontal force, causing the guide wheel to rotate and further elastically deflect on the elastic deflection mechanism, thereby transmitting the horizontal force to the driven mechanism again, causing the driven mechanism to move again, so as to achieve secondary positioning of the driving mechanism. The action of the second guide slope and the elastic deflection mechanism enables the driving mechanism and the driven mechanism to perform secondary position correction, making the guiding effect more accurate and efficient.

[0015] Preferably, the guide plates and elastic deflection mechanisms are symmetrically arranged at the four diagonal positions of the active mechanism and the driven mechanism. When the first guide inclined surface is pressed against the annular outer wall of the guide wheel, the driven mechanism is subjected to the horizontal force generated by the compression and moves in the horizontal direction to achieve the position alignment of the active mechanism. The guide plates at the four diagonal positions and the elastic swing mechanism are pressed together to make the driven mechanism directly generate horizontal displacement to achieve position alignment and improve the guiding efficiency.

[0016] Preferably, the active mechanism is a clamping mechanism for holding the brush roller, and the driven mechanism is a supporting mechanism for supporting the brush roller. The clamping mechanism can move up and down relative to the supporting mechanism and cooperate with the supporting mechanism. The supporting mechanism can be guided by an elastic guiding mechanism to achieve positional alignment with the clamping mechanism in order to complete the loading and unloading process of the brush roller. Before changing the roller, the supporting mechanism is aligned with the clamping mechanism through the elastic guiding mechanism to avoid collision of parts during the roller changing process and improve the service life of the clamping mechanism and the supporting mechanism.

[0017] The principle of the present invention, which adopts the above technical solution, is as follows:

[0018] The present invention provides an elastic guiding mechanism, which generates a horizontal force through the pressing cooperation between the guide wheel and the guide plate on the elastic swing mechanism. At the same time, the horizontal force is gradually transmitted to the driven mechanism through the rotation and elastic deflection process of the guide wheel, so that the driven mechanism can align with the driving mechanism.

[0019] The beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0020] The first guide slope on the guide plate allows the guide plate and the guide wheel to gradually press together, preventing the guide wheel from being subjected to instantaneous impact during the fit, which could cause excessive deformation of the guide wheel or damage to the contact surface, thus improving the service life of the guide wheel.

[0021] When the guide wheel is compressed by radial external force, the swing arm and elastic telescopic component on the elastic deflection mechanism enable the guide wheel to evenly transmit the compression force to the driven mechanism. While performing guiding coordination, it reduces the impact generated when the main mechanism and the driven mechanism cooperate. Attached Figure Description

Detailed Implementation

[0053] 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.

[0054] 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.

[0055] 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.

[0056] The specific implementation methods of this invention are as follows:

[0057] Example 1: Figure 1-28b As shown, this embodiment provides an elastic guiding mechanism, which is symmetrically arranged between the active mechanism and the driven mechanism. For ease of explanation, the active mechanism in this embodiment is configured as a clamping roller mechanism 1 that holds the brush roller 4 on the steel plate brushing area s within the frame of the steel plate brushing equipment and can move up and down. The driven mechanism is a support mechanism 3 that supports the brush roller 4. The elastic guiding mechanism is arranged in the front-back direction between the support mechanism 3 and the clamping roller mechanism 1. Therefore, the elastic guiding mechanism is the front-back guiding component between the support mechanism 3 and the clamping roller mechanism 1. The clamping roller mechanism 1 can move up and down relative to the support mechanism 3 and cooperate with the support mechanism 3. The support mechanism 3 can be aligned with the clamping roller mechanism 1 through the guidance of the elastic guiding mechanism to complete the loading and unloading process of the brush roller 4. This avoids collisions between components during the roller changing process and improves the service life of the clamping roller mechanism 1 and the support mechanism 3.

[0058] like Figure 11-28b As shown, the elastic guiding mechanism includes a guide plate 103 and an elastic deflection mechanism 33 respectively disposed on the clamping roller mechanism 1 and the supporting mechanism 3. The elastic deflection mechanism 33 is provided with a circumferentially rotatable guide wheel 331. Under the compression of radial external force, the guide wheel 331 can generate elastic deflection on the elastic deflection mechanism 33. The guide plate 103 is provided with a first guiding inclined surface 104. When the clamping roller mechanism 1 and the supporting mechanism 3 cooperate, the first guiding inclined surface 104 and the annular outer wall surface of the guide wheel 331 are compressed to generate a horizontal force. At this time, the guide wheel 331 rotates and undergoes elastic deflection on the elastic deflection mechanism 33, thereby gradually transmitting the generated horizontal force to the supporting mechanism 3, so that the supporting mechanism 3 moves to a position aligned with the clamping roller mechanism 1.

[0059] like Figure 1-10As shown, the clamping roller mechanism 1 is controlled by a drive element and can slide horizontally and vertically. The drive element (not shown) is usually a controlled hydraulic component. Its working principle can be found in the specific structure of the lifting motor 135, the angler 136, the connecting shaft 137, and the lifting mechanism 138 in the patent with publication number CN211103286, which will not be described in detail 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 rotating between the stationary mechanism 102 and the sliding mechanism 101. The axis of the old brush roller 4a is in the left-right direction. The sliding mechanism 101 can slide horizontally to install or disengage the old brush roller 4a on the clamping roller mechanism 1. The stationary mechanism 102 and the sliding mechanism 101 are equivalent to the bearing seats 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 mechanism 102. The motor drives the components in the walking mechanism, 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 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.

[0060] Furthermore, the support mechanism 3 on the roller changing car includes a base 32 and a support seat 31. The support seat 31 is located above the base. In order to make the sliding of the support seat 31 smoother, a guide rail 321 is provided above the base 32, and a guide groove 316 is provided below the support seat 31. The guide rail 321 and the guide groove 316 cooperate to allow the support seat 31 to slide relative to the base 32 along its own length direction.

[0061] Furthermore, a telescopic member 312 is provided above at least one end of the support 31. The telescopic member 312 can extend or retract along its own length. In order to generate sufficient thrust to push the old brush roller 4a and the support 31, the telescopic member 312 is usually a hydraulic cylinder. The hydraulic cylinder is provided with a telescopic rod 313, which extends or retracts along the length of the telescopic member 312. Considering the spatial layout and the size of the old brush roller 4a, the extension range of the telescopic rod 313 along the length of the telescopic member 312 is set to 5cm-20cm.

[0062] Furthermore, the sliding mechanism 101 in the clamping roller 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 clamping roller 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 clamping roller mechanism 1, setting the left end of the clamping roller mechanism 1 as a sliding mechanism would make the axial structure of the clamping roller mechanism 1 bulky. Repeated sliding would also require the motor and the old brush roller 4a to be frequently connected and disconnected. 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 is difficult to process. The complexity, design difficulty, and manufacturing cost will all increase dramatically. Therefore, in order to detach the left end of the old brush roller 4a, a telescopic member 312 is provided above at least one 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 traveling 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, detaching the left end of the old brush roller 4a. Since the telescopic member 312 is located above the end of the support 31 and closer to the end of the old brush roller 4a, even if the telescopic rod 313 of the telescopic member 312 pushes against the bearing seat, it will not generate a long lever arm at the stuck end of the old brush roller 4a shaft. Therefore, the stuck force is also small, and it is easier to detach the old brush roller 4a shaft end, without causing the roller seat to tip over.

[0063] Furthermore, in order for the telescopic component 312, which acts as a hydraulic cylinder, to generate telescopic force, hydraulic oil pipes are usually connected to both ends of it. However, if the hydraulic oil pipes are exposed, they are prone to rubbing against the clamping roller mechanism 1 when the rollers are connected, which will affect the working state of the telescopic component 312. Therefore, in order to protect the telescopic component 312 so that it can work normally, a support 311 fixed on the support seat 31 is provided below the telescopic component 312. The hydraulic oil pipes connected to the head and tail ends of the telescopic component 312 are passed through the support 311. The hydraulic oil pipes are retracted inside the support 311 to prevent the oil pipes from shaking during operation and to avoid interference and rubbing against the clamping roller mechanism 1.

[0064] Furthermore, to make the process of the support 31 and the old brush roller 4a sliding off the base 32 smoother, the telescopic component 312 and the support are symmetrically arranged on the support 31. When the support 31 slides, the symmetrical telescopic component 312 exerts force on both the front and rear sides at the same time, so that the shaft end of the old brush roller 4a quickly and smoothly disengages from the clamping roller mechanism 1.

[0065] Furthermore, if the telescopic component 312 only has one support point at the end of the support seat 31, then the telescopic rod 313 will inevitably generate a torsional effect on the support point due to gravity when it extends, causing the telescopic component 312 to sway up and down. Therefore, a support member R is provided above the opposite end of the support 311 and the support seat 31. The support member R is connected to the cylinder of the telescopic component 312 and provides support for the head of the telescopic component 312. This forms two support points for the telescopic component 312, so that the telescopic component 312 can be stably supported during operation, avoiding the situation where the telescopic component 312 sways up and down.

[0066] like Figure 26 As shown, the support 31 includes a base plate 319 and end plates W. The end plates W are symmetrically arranged at both ends of the support 31 along its length. The end plates W serve as support plates for receiving the shaft ends of the old brush roller 4a. Between the two symmetrical end plates W, there are vertical plates 318 symmetrically arranged along the width of the support 31. The base plate 319 and the vertical plates 318 are symmetrically provided with weight-reducing holes K to reduce the weight of the roller seat. This ensures the structural strength of the roller seat and reduces the weight of the entire support 31, making it easier to slide when the base 32 is in place. The base plate 319, end plates W, and vertical plates 318 form a box-shaped receiving area that can accommodate the brush roller 4 and has an opening at the top. This ensures that when the old brush roller 4a falls on the support 31, it can remain horizontally fixed and will not roll or fall off the support 31.

[0067] Furthermore, to ensure the structural strength of the roller seat, a reinforcing rib plate Q is connected between the end plate W and the bottom plate 319. The reinforcing rib plate Q is symmetrically arranged on the inner and outer sides of the box-shaped receiving area to provide stable support for the old brush roller 4a inside. The end plate W is symmetrically provided with L-shaped fixing blocks 314 along the width direction of the support seat 31. The L-shaped fixing blocks 314 are limiting components that restrict the brush roller 4a along the length direction of the support seat 31. When the old brush roller 4a falls on the support seat 31, the L-shaped fixing blocks 314 lock it between the two ends of the support seat 31 to prevent the old brush roller 4a from rolling off the support seat 31.

[0068] like Figure 18 As shown, in order to enable the support 31 to be quickly held in place before being connected to the old brush roller 4a, a positioning telescopic component 312 is provided above the base 32. The positioning telescopic component 312 is a cylinder, and a positioning telescopic rod 313 is provided inside the cylinder. The head of the positioning telescopic component 312 is connected to the lower part of the support 31 and can drive the support 31 to slide along its own length direction and hold it in place. In order to limit the excessive sliding of the positioning telescopic rod 313, a limiting seat 317 is provided below the support 31. When the positioning telescopic rod 313 drives the support 31 to slide along its own length direction into place, the limiting seat 317 abuts against the tail of the cylinder of the positioning telescopic component 312, limiting the support 31 from continuing to slide.

[0069] Furthermore, to avoid the positioning telescopic component 312 occupying the space of the roller seat, the positioning telescopic component 312 is positioned between the base 32 and the support 31, thus being covered by the support 31. To enable quick assembly and disassembly of the positioning telescopic component 313 and the support 31, the head of the positioning telescopic component 313 is designed with a T-shaped structure. A T-shaped connecting sleeve 315 is provided at the corresponding position below the support 31, and the T-shaped structure is inserted into the T-shaped connecting sleeve 315, so that the head of the positioning telescopic component 312 is connected to the support 31. This plug-in design makes the connection between the support 31 and the positioning telescopic component 312 more convenient and faster, and the ease of assembly and disassembly also makes the positioning telescopic component 312 easier to maintain and repair later.

[0070] like Figure 17-21 As shown, a forward-moving mechanism 2 is provided below the base 32. The moving mechanism 2 remains fixed in the vertical direction and can move freely relative to the ground in the front-back direction. The moving mechanism 2 includes a frame-shaped moving chassis 21. Pulleys are provided on the left and right sides of the moving chassis 21. A motor is provided at the rear of the moving chassis 21. The motor and the connecting mechanism drive the pulleys to move the moving mechanism 2 on the slide rail a. In order to keep the direction of the moving mechanism 2 of this new type of support unchanged during movement, a slide rail a is also provided on the ground. The slide rail a separates the new type of support from the ground, so that the moving mechanism 2 can move forward more smoothly on the slide rail a, without worrying about the new type of support deflecting.

[0071] like Figure 17 As shown, in order to keep the traveling chassis 21 fixed during unloading roller guidance and clamping roller guidance, a positioning structure is provided between the traveling mechanism 2 and the ground. The positioning structure includes a limiting telescopic component 211 and a positioning seat d. The limiting telescopic component 211 is set on the traveling chassis 21 of the traveling mechanism 2 and can extend and retract vertically. The limiting telescopic component 211 is usually a cylinder, and a limiting telescopic rod 212 is set inside it. The head of the limiting 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 traveling mechanism 2 needs to stop, the head of the limiting telescopic rod 212 is inserted into the V-shaped groove, so that the traveling mechanism 2 remains fixed front and back.

[0072] In this embodiment, the unused new brush roller 4b is placed on the rear support 31 in advance. The old brush roller 4a and the new brush roller 4b are the same size. When they are placed on the support 31, both ends of them are restricted to move in the left and right directions by the L-shaped fixing blocks 314 corresponding to the support 31. The only difference is that the old brush roller 4a is the 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. The telescopic component 312 is usually a hydraulic cylinder. The telescopic component 312 contains a telescopic rod 313, which can move along the... 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 2 in the new support seat and for the convenience of maintenance and management of the support mechanism 2, 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.

[0073] like 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 traveling 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.

[0074] Furthermore, the limiting telescopic component 211 is controlled by a receiving unit (not shown). The receiving unit can be a sub-controller. When the traveling 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 traveling 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 limiting telescopic rod 212 to retract and disengage from the positioning seat d, thereby allowing the traveling mechanism 2 to move forward.

[0075] To prevent the brush roller 4 from colliding or bouncing relative to the support 31 when placed on it, an elastic support mechanism 22 is provided between the upper end of the traveling 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 traveling 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. The upper and lower ends of the elastic support mechanism 22 are hinged to the support mechanism 3 and the traveling mechanism 2, respectively. 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.

[0076] Specifically, both the base 32 and the traveling 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.

[0077] 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 provides floating support for the old brush roller 4a while protecting the support mechanism 3 and the traveling mechanism 2 to the greatest extent.

[0078] 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.

[0079] 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 provided on the left and right sides above the walking mechanism 2. The deflection support mechanism includes a column 24 and an elastic return wheel 34. The elastic return 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 return wheels 34 that abut against it. When the first guide inclined surface 104 is pressed and engaged with the elastic swing mechanism 33, the base 32 generates a tendency to move in the front-back direction, and drives the elastic return wheel 34 to generate elastic deformation. It is equivalent to the elastic return 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, avoiding the brush roller 4 from tipping over on the support mechanism 3.

[0080] Furthermore, such as Figure 16 As 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 a reverse support elastic force for the base 32, the elastic reset wheel 34 can also use the good 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 support mechanism 22.

[0081] Furthermore, such as Figure 23-25As shown, guide wheels typically rely on the elastic deformation of their own material for guidance. However, when a guide wheel is subjected to a large compressive load, the material of the guide wheel itself may break. Therefore, in this embodiment, to ensure that the supporting mechanism 3 is subjected to uniform force, an elastic swing mechanism 33 is used. The elastic swing mechanism 33 includes a base 338 fixed on the base 32. A swing assembly is hinged to the base 338 via a second pin 334. The swing assembly includes a swing arm 332. A rotatable guide wheel 331 is hinged to the swing arm 332 via a first pin 333. The guide wheel 331 is usually made of rubber material with good resilience. In order for the guide wheel 331 to rotate and generate elastic compression when it is squeezed by the walking mechanism 1, the following measures are taken.

[0082] Furthermore, a connecting shaft 339 is fixed on the swing arm 332. The washer 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 arm 332 are not squeezed by the guide plate 103, the swing arm 332 will abut against the horizontal plate 335. When the guide wheel 331 and the swing arm 332 are squeezed by the guide plate 103, the swing arm 332 and the guide wheel 331 will elastically swing relative to the base 338. The guide wheel 331 and the swing arm 332 have a swing angle b relative to the base 338. The swing angle b is usually 3°-10°.

[0083] Furthermore, during the guiding process, the swing arm 332 and the elastic telescopic member 337 transform the deformation process of the guide wheel 331 into the elastic deflection process of the swing arm 332, avoiding damage caused by excessive deformation of the guide wheel 331 under force. When the guide wheel 331 is not subjected to radial external force, the elastic telescopic member 337 is in a compressed state between the swing arm 332 and the base 338. The compressed elastic telescopic member 337 will generate an elastic preload between the swing arm 332 and the base 338, making the elastic swing effect of the elastic swing mechanism better. When the guide wheel 331 is subjected to radial external force, the elastic telescopic member 337 is further compressed, causing the guide wheel 331 to undergo elastic deflection on the elastic deflection mechanism 33. The elastic force generated by further compression will gradually increase to better adapt to the squeezing fit effect between the guide plate 103 and the guide wheel 331.

[0084] In this embodiment, the elastic guiding mechanism aligns the supporting mechanism 3 with the clamping roller mechanism 1 through two steps: a distance measurement step and a return-to-center step. During the distance measurement step, when the guide plate 103 presses against the guide wheel 331 on the elastic swing mechanism 33, the supporting mechanism 3 is not yet aligned with the clamping roller mechanism 1. Therefore, although the clamping roller mechanism 1 can smoothly cooperate with the supporting mechanism 3 through the contact guidance process of the guide plate 103 and the elastic deflection mechanism 33, the left end of the supporting mechanism 3 will still exhibit horizontal deflection. The deviation distance of the supporting mechanism 3 can be determined by the deflection distance of the supporting mechanism 3. After the distance measurement step is completed, the return-to-center step begins. Therefore, reset supports, namely strip support plates 105, are symmetrically arranged at the front and rear of the right end of the clamping roller mechanism 1. The thickness of 105 is less than that of guide plate 103; when the first guide inclined surface 104 is pressed against the annular outer wall of guide wheel 331, the driven mechanism deflects on the horizontal plane. The corresponding position on the support mechanism 3 is also provided with an elastic deflection mechanism 33 that acts with the reset support member. When the first guide inclined surface 104 is pressed against the annular outer wall of guide wheel 331, the driven mechanism deflects on the horizontal plane. The reset support member can press against the guide wheel 331 on the corresponding elastic deflection mechanism 33 to generate a reset elastic force, causing the driven mechanism to rotate in the opposite direction and return to the center. The strip support plate 105 can act with the elastic swing mechanism 33 to generate a return elastic force on the support mechanism 3, so that the support mechanism 3 moves back to the center while automatically correcting the deviation distance along the deviation direction and aligning with the clamping roller mechanism 1 again.

[0085] Furthermore, such as Figure 28a As shown, the deflection distance of the support mechanism 3 is less than or equal to the thickness difference between the strip support plate 105 and the guide plate 103; and the thickness difference between the guide plate 103 and the strip support plate 105 is in the range of 1mm-10mm. The thickness difference provides deflection space margin for the offset of the support mechanism 3, so as to make it easier to measure the deviation distance between the main clamping roller mechanism 1 and the support mechanism 3.

[0086] Furthermore, such as Figure 28b As shown, after the supporting mechanism 3 rotates in the reverse direction and returns to the center, the strip support plate 105 and the guide plate 103 simultaneously compress the guide wheel 331 on the corresponding position of the elastic deflection mechanism 33 on the driven mechanism, thereby forming four cooperation support points between the active mechanism and the driven mechanism. The four cooperation support points can provide stable support for the sliding cooperation between the clamping roller mechanism 1 and the supporting mechanism 3, so that the supporting mechanism 3 will not deflect or move significantly when cooperating with the clamping roller mechanism 1.

[0087] Furthermore, after being guided by the first guide slope 104 and the guide wheel 331, the supporting mechanism 3 is basically aligned with the clamping roller mechanism 1. However, in order to further reduce the positional deviation between the supporting mechanism 3 and the clamping roller mechanism 1, the outer plane above the first guide slope 104 on the guide plate 103 contracts downward and inward, thereby forming a second guide slope 108 on the outer plane of the guide plate 103. When the guide wheel 331 rolls over the first guide slope 104, it will squeeze and cooperate with the second guide slope 108 to generate a horizontal force, causing the guide wheel 331 to rotate and further elastically deflect on the elastic deflection mechanism 33, thereby transmitting the horizontal force to the driven mechanism again, causing the driven mechanism to move again, so as to achieve secondary positional alignment of the driving mechanism. In other words, the action of the second guide slope 108 and the elastic deflection mechanism 33 enables the supporting mechanism 3 to perform secondary positional correction on the clamping roller mechanism 1, making the guiding effect more accurate and efficient.

[0088] like Figure 11-27 As shown, the guide assembly in the left-right direction includes a guide support 35 and a rotating sleeve 107. The guide support 35 has a guide groove 352, and the opening above the guide groove 352 extends outward in the direction above the guide support 35, thereby forming two symmetrical inclined surfaces 351 above the guide support 35. The guide support 35 is set on the clamping roller mechanism 1, and the rotating sleeve 107 is set on the supporting mechanism 3. The guide groove 352 is set through the guide support 35 along the thickness direction of the plate. When the rotating sleeve 107 is pressed and engaged with the inclined surface 351 of the guide groove 352, the inclined surface 351 of the guide support 35 is subjected to the horizontal force applied by the rotating sleeve 107, causing the supporting mechanism 3 to have a horizontal movement tendency and gradually align with the clamping roller mechanism 1.

[0089] Specifically, the clamping roller mechanism 1 is provided with a support part, which is a column fixed on the clamping roller mechanism 1. The rotating sleeve 107 is a cylindrical component that is sleeved on the support part and can rotate circumferentially. The sleeved rotating sleeve 107 can rotate, making the guiding process smoother and facilitating disassembly and assembly from the support part. In order to allow the rotating sleeve 107 to slide in the guide groove 352, the width of the guide groove 352 is set to be greater than the diameter of the rotating sleeve 107, and the difference between the width of the guide groove 352 and the diameter of the rotating sleeve 107 is in the range of 1mm-3mm. This ensures that after the rotating sleeve enters the guide groove 352, it forms a clearance fit with the guide groove 352, and the phenomenon of guidance jamming will not occur.

[0090] Furthermore, such as Figure 11As 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: Since the rotating sleeve 107 can rotate circumferentially around the support, while the rotating sleeve 107 is pressed against the inclined surface 351 of the guide groove 352, the rotating sleeve 107 rotates close to the inclined surface 351, causing the rotating sleeve 107 to roll into the guide groove 352 along the inclined surface 351. Compared with the sliding friction generated by the single pressing, the rolling friction generated by the contact pressing between the rotating sleeve 107 and the inclined surface is smaller, making the guiding process of the supporting mechanism 3 in aligning with the clamping roller mechanism 1 smoother. When the rotating sleeve 107 is pressed against the inclined surface 351 of the guide groove 352, the supporting mechanism 3 moves in the horizontal direction, causing the elastic reset wheel 34 to abut against the cylindrical body 24 and undergo elastic deformation, and gradually align with the clamping roller mechanism 1. This ensures that the brush roller 4 is aligned with the supporting mechanism 3 by the guiding mechanism before falling into the supporting mechanism 3, avoiding interference and collision between the brush roller 4 and the supporting mechanism 3.

[0091] like Figure 18-27 As shown, the extended positioning 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 traveling mechanism and drives the support seat 31 to disengage to the right. If the positioning 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.

[0092] 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.

[0093] like Figure 18-22As 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.

[0094] Furthermore, such as Figure 22 As 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 chassis of the traveling 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 traveling 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 traveling mechanism 2. The elastic element 233 can be hooked between the rotating seat 232 and the traveling chassis 21. 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.

[0095] As shown in Figure 8, 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 will offset part of the weight of the new brush roller 4b due to the upward release of the elastic force of the elastic support mechanism 22, 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.

[0096] Example 2: As Figure 29 As shown, the difference between this embodiment and Embodiment 1 is that, in order to prevent the supporting mechanism 3 from deflecting relative to the clamping roller mechanism 1 and instead align itself with the clamping roller mechanism 1 directly through horizontal movement, the original position of the strip support plate 105 on the clamping roller mechanism 1 is replaced by a guide plate 103. The guide plate 103 and the elastic deflection mechanism 33 are symmetrically arranged at the four diagonal positions of the clamping roller mechanism 1 and the supporting mechanism 3. When the first guide inclined surface 104 is pressed against the annular outer wall of the guide wheel 331, the supporting mechanism 3 no longer deflects, but is subjected to the horizontal force generated by the compression at the four sliding support points and moves in the horizontal direction to achieve the alignment of the clamping roller mechanism 1. At this time, the compression cooperation between the guide plate 103 at the four diagonal positions and the elastic swing mechanism 33 makes the horizontal movement of the supporting mechanism 3 more stable and improves the guiding efficiency.

[0097] 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.

The elastic guiding mechanism according to claim 4, characterized in that: After the driven mechanism rotates in the opposite direction and returns to the center, the strip support plate (105) and guide plate (103) on the driving mechanism simultaneously squeeze the guide wheel (331) on the elastic deflection mechanism (33) at the corresponding position on the driven mechanism, thereby forming four cooperating support points between the driving mechanism and the driven mechanism.

6. The elastic guiding mechanism according to claim 1, characterized in that: The guide plate (103) and the elastic deflection mechanism (33) are symmetrically arranged at the four diagonal positions of the active mechanism and the driven mechanism. When the first guide inclined surface (104) is pressed against the annular outer wall of the guide wheel (331), the driven mechanism is subjected to the horizontal force generated by the compression and moves in the horizontal direction to realize the position alignment of the active mechanism.

7. The elastic guiding mechanism according to claim 1, characterized in that: The active mechanism is a clamping mechanism (1) that clamps the brush roller (4), and the driven mechanism is a supporting mechanism (3) that supports the brush roller (4). The clamping mechanism (1) can move up and down relative to the supporting mechanism (3) and cooperate with the supporting mechanism (3). The supporting mechanism (3) can be guided by the elastic guiding mechanism to achieve position alignment with the clamping mechanism (1) in order to complete the loading and unloading process of the brush roller (4).
