Description

Technical Field

[0001] The utility model relates to the field of metal surface treatment, in particular to a guiding mechanism. Background Art

[0002] After the production of steel plates is completed, they will be made into corresponding parts according to different usage requirements. However, before the steel plates are put into the production process, preparation time for processing the steel plates must always be reserved. During this period of time, the steel plates will react with moisture and chemicals in the air, causing the surface material of the steel plates to peel off or rust. In order to remove the rust layer, the existing environmental protection equipment is a grinding equipment that removes rust by grinding the surface of the steel plates. This equipment physically grinds the surface of the steel plates by installing brush rollers, which improves the rust removal efficiency of the steel plates and reduces pollution. However, this equipment requires the brush roller to contact the surface of the steel plates during grinding. After long-term use, the grinding effect of the brush roller will decrease. Therefore, the brush roller needs to be placed on the roller changing operation vehicle and replaced with a new roller. During the brush roller replacement process, the steel plate needs to be ground. The clamping roller mechanism on the equipment moves down with the old brush roller and places the brush roller on the roller seat of the roller changing vehicle; however, due to equipment errors, the clamping roller mechanism and the roller changing vehicle cannot be completely 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, resulting in frequent collisions between the brush roller and the roller changing vehicle parts 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 vehicle. The existing improvement plan is to design a guide wheel on the roller changing vehicle that receives the brush roller, wherein the guide wheel is made of flexible material. When the falling position of the brush roller deviates, the end of the brush roller is squeezed against the guide wheel, and the impact force of the brush roller on the roller changing vehicle is absorbed by the deformation of the guide wheel itself, but such a design has defects.

[0003] For example, in the patent for the roll changing device in publication number CN216371699, as in the patent Fig.10 As shown, a supporting member, that is, a rotatable guide wheel, is arranged above the roller changing device. During the process of supporting the brush roller, even if the center position of the brush roller does not fall exactly in the middle of the two guide wheels, the guide wheel can be used to carry out the rotation to guide the brush roller, so that the brush roller rolls back to the center position of the roller seat; although this can reduce the impact of the brush roller on the roller changing vehicle, it is equivalent to forcibly adding the impact force of the brush roller to the guide wheel. Therefore, the guide wheel will be damaged after absorbing the impact many times. If the guide wheel is replaced frequently, the precise positioning of the roller changing device will also be affected. Therefore, although this guiding method avoids the rigid collision between the brush roller and the roller changing vehicle, its guiding effect is not ideal. Summary of the invention

[0004] In order to solve the above-mentioned technical problems, the purpose of the utility model is to provide a guiding mechanism, which is arranged between an active mechanism and a driven mechanism, and includes a first guide member and a second guide member for guiding through the inclined surface extrusion cooperation of the components, so that the driven mechanism can be horizontally moved by the horizontal force generated by the inclined surface extrusion to achieve alignment of the active mechanism, thereby improving the guiding efficiency, avoiding collision between components on the active mechanism and the driven mechanism, and increasing the service life of each component.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A guide mechanism is symmetrically arranged between an active mechanism and a driven mechanism, and comprises a first guide member and a second guide member, wherein a guide groove is provided on the first guide member, and an opening above the guide groove extends outwardly above the first guide member, thereby forming two symmetrical inclined surfaces above the first guide member; when the active mechanism cooperates with the driven mechanism, the horizontal force generated by the second guide member and the inclined surface of the guide groove squeezing into the guide groove can drive the driven mechanism to align the position of the active mechanism along the horizontal direction.

[0007] Preferably, the first guide member is arranged on the driven mechanism, and the second guide member is arranged on the active mechanism. When the second guide member is squeezed and matched with the inclined surface of the guide groove, the inclined surface of the first guide member is subjected to the horizontal force exerted by the second guide member, so that the driven mechanism has a horizontal movement tendency and gradually aligns with the active mechanism; the first guide member moves synchronously with the driven mechanism and gradually approaches the second guide member until the second guide member falls into the guide groove, thereby smoothly completing the guiding process.

[0008] Preferably, the first guide member is connected to the active mechanism, and the second guide member is connected to the driven mechanism. When the second guide member is squeezed into fit with the inclined surface of the guide groove, the second guide member is subjected to the horizontal force exerted by the inclined surface, so that the driven mechanism has a tendency to move horizontally and gradually aligns with the active mechanism; the second guide member moves synchronously with the driven mechanism and gradually approaches the first guide member until the second guide member falls into the guide groove, thereby smoothly completing the guiding process.

[0009] Preferably, the first guide member is a plate connected to the active mechanism or the driven mechanism, and the guide groove is arranged on the first guide member along the thickness direction of the plate; the structure of the plate itself is simple and reliable, while ensuring the structural strength of the guide member itself.

[0010] Preferably, the thickness of the first guide member is in the range of 5 mm to 10 mm; the thickness of the first guide member is controlled within a reasonable range so that the second guide member has sufficient supporting area when in contact with the inclined surface.

[0011] Preferably, a support portion is provided on the active mechanism or the driven mechanism, and the second guide member is a cylindrical member which is sleeved on the support portion and can rotate circumferentially; the sleeved second guide member can rotate to make the guiding process smoother and is also convenient for disassembly and assembly with the support portion.

[0012] Preferably, the width of the guide groove below the inclined surface is greater than the diameter of the second guide member, and the difference between the guide groove width and the second guide member diameter is in the range of 1mm-3mm; so that the second guide member can slide smoothly after entering the guide groove without the guide being stuck.

[0013] Preferably, the second guide member is pressed and fitted with the inclined surface of the guide groove while the second guide member rotates close to the inclined surface so that the second guide member rolls into the guide groove along the inclined surface; the second guide member is pressed and contacted with the inclined surface while also rolling on the inclined surface, making the guiding process smoother.

[0014] Preferably, the active mechanism is a clamping roller mechanism that clamps the brush roller and can move up and down, and the driven mechanism is a supporting mechanism that supports the brush roller. When the second guide member is squeezed and fitted with the inclined surface above the guide groove, the supporting mechanism moves in the horizontal direction and gradually aligns with the clamping roller mechanism; before the brush roller falls onto the supporting mechanism, the brush roller and the supporting mechanism are aligned through the guide mechanism to avoid interference and collision between the brush roller and the supporting mechanism.

[0015] The principle of the utility model using the above technical solution is:

[0016] The utility model provides a guiding mechanism, which relies on a first guiding member and a second guiding member for guiding by means of inclined surface extrusion of a component, so that a driven mechanism can be horizontally moved by a horizontal force generated by the inclined surface extrusion, so as to realize alignment of an active mechanism.

[0017] The beneficial effects of the utility model using the above technical solution are:

[0018] The symmetrical inclined surface above the guide groove is equivalent to the transition surface of the component contact guide, so that the second guide member can smoothly perform the extrusion guiding process when in contact with the inclined surface, and the component will not be damaged due to direct collision, thereby improving the service life of the guide mechanism.

[0019] The horizontal force component generated by the second guide member when it contacts and extrude the inclined surface is used as the driving force for the driven mechanism to align its position, so that the driven mechanism itself moves in the corresponding direction, making the alignment process between the driven mechanism and the active mechanism accurate and efficient.

Implementation

[0050] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0051] The utility model provides specific implementation methods as follows:

[0052] Example 1: Figure 1-28aAs shown, the present embodiment provides a guiding mechanism, which is symmetrically arranged between the active mechanism and the driven mechanism. For the convenience of explanation, the active mechanism in the present embodiment is configured as a clamping roller mechanism 1 that clamps the brush roller 4 and can move up and down on the steel plate brushing area s in the steel plate brushing equipment in the frame, and the driven mechanism is a supporting mechanism 3 that receives the brush roller 4. The guiding mechanism is arranged in the left and right directions of the supporting mechanism 3 and the clamping roller mechanism 1. Therefore, the guiding mechanism is a left and right guiding component of the supporting mechanism 3 and the clamping roller mechanism 1, which includes a first guide member 35 and a second guide member 107. The first guide member 35 is provided with a guiding groove 352, and the upper opening of the guide groove 352 extends outward on the first guide member 35, thereby forming two symmetrical inclined surfaces 351 above the first guide member 35; when the active mechanism cooperates with the driven mechanism, the horizontal force generated by the second guide member 107 and the inclined surface 351 of the guide groove 352 that squeezes into the guide groove 352 can drive the driven mechanism to align the position of the active mechanism along the horizontal direction.

[0053] like Figure 1-10 As shown, the roller clamping mechanism 1 is controlled by a driving element and can slide in the up, down, left and right directions; the driving element (not shown) is usually a controlled hydraulic component, and its working principle can refer to the specific structure of the lifting motor 135, the angler 136, the connecting shaft 137 and the lifting mechanism 138 in the patent with the announcement number CN211103286, which will not be repeated here; the roller clamping mechanism 1 includes a stationary mechanism 102 and a sliding mechanism 101, and an axially fixed and circumferentially rotating old brush roller 4a is provided between the stationary mechanism 102 and the sliding mechanism 101, and the axial direction of the old brush roller 4a is the left and right direction; the sliding mechanism 101 can slide in the left and right direction to install the old brush roller 4a in place or disengage it on the roller clamping mechanism 1; the stationary mechanism 102 and the sliding mechanism 101 are equivalent to the bearing seat of the old brush roller 4a, and the left end of the bearing seat is the stationary mechanism 102 that does not move. A motor is connected to the left end of the mechanism 102, and the motor drives the components in the walking mechanism to make the old brush roller 4a 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 an air cylinder or an oil cylinder, and the sliding position of the sliding bearing seat can be controlled by controlling the extension and contraction of the air cylinder or the oil cylinder, and the left and right sliding of the sliding mechanism 101 is controlled. The sliding mechanism 101 is controlled by a control unit (not shown), for example, the control unit can be a master controller; only when the control unit sends an instruction, the oil cylinder or air cylinder in the sliding mechanism 101 will pull the bearing seat to slide, and 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, and when the sliding mechanism 101 slides to the right, the right end of the old brush roller 4a loses the support point for circumferential rotation, thereby causing the old brush roller 4a to escape from the clamping roller mechanism 1.

[0054] Furthermore, the supporting mechanism 3 on the roller changing vehicle includes a base 32 and a supporting seat 31. The supporting seat 31 is arranged above the base. In order to make the sliding of the supporting seat 31 smoother, a guide rail 321 is provided above the base 32, and a guide groove 316 is provided below the supporting seat 31. The guide rail 321 cooperates with the guide groove 316 to enable the supporting seat 31 to slide relative to the base 32 along its own length direction.

[0055] Furthermore, a telescopic member 312 is provided above at least one end of the supporting seat 31, and the telescopic member 312 can be extended or retracted along its own length direction; in order to generate sufficient thrust to push the old brush roller 4a and the supporting seat 31, the telescopic member 312 is usually a hydraulic cylinder, and a telescopic rod 313 is provided in the hydraulic cylinder, and the telescopic rod 313 is extended or retracted along the length direction of the telescopic member 312; considering the spatial layout and the size of the old brush roller 4a, the telescopic range of the telescopic rod 313 along the length direction of the telescopic member 312 is set to 5cm-20cm.

[0056] 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 supporting seat 31, the control unit sends a command to the sliding mechanism 101 to slide to the right and disengage 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 why a sliding mechanism 101 is not set at the left end of the clamping roller mechanism 1 is that the stationary mechanism 102 at the left end is connected to a motor, and the motor drives the old brush roller 4a to rotate to grind the steel plate. Since the existence of the motor has occupied the axial space of the clamping roller mechanism 1, setting the left end of the clamping roller mechanism 1 as a sliding mechanism will make the axial structure of the clamping roller mechanism 1 bloated, and repeated sliding will also require frequent connection and disconnection of the motor and the old brush roller 4a. In order to ensure that the connection between the motor and the old brush roller 4a is well matched, a positioning mechanism must be added again, which is difficult to process. The degree, design difficulty and manufacturing cost will all rise linearly. Therefore, in order to disengage the left end of the old brush roller 4a, a telescopic member 312 is provided above at least one end of the supporting seat 31, and the telescopic rod 313 in the telescopic member 312 is extended to abut against the vertical plate at the end of the walking mechanism 101. At this time, the clamping roller mechanism 1 is in a stationary state. After being subjected to the abutment force of the telescopic rod 313, a reaction force will be generated on the supporting seat 31, and the supporting seat 31 will slide to the right along the guide rail 321 to disengage the left end of the old brush roller 4a. Moreover, since the telescopic member 312 is located above the end of the supporting seat 31 and is 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 force arm at the stuck position of the shaft end of the old brush roller 4a. Therefore, the stuck force is also small, and it is also easier to disengage the shaft end of the old brush roller 4a, and the roller seat will not tip over.

[0057] Furthermore, in order to enable the telescopic member 312 serving as a hydraulic cylinder to generate a telescopic force, hydraulic oil pipes are usually connected at both ends thereof. However, if the hydraulic oil pipes are exposed to the outside, they are prone to scratching against the clamping roller mechanism 1 when connecting the rollers, thereby affecting the working state of the telescopic member 312. Therefore, in order to protect the telescopic member 312 to work normally, a support 311 fixed on the supporting seat 31 is provided under the telescopic member 312. A hydraulic oil pipe connected to the head and tail ends of the telescopic member 312 is passed through the support 311. The hydraulic oil pipe is gathered inside by the support 311 to prevent the oil pipe from shaking during operation and to avoid interference and scratching with the clamping roller mechanism 1.

[0058] Furthermore, in order to make the sliding disengagement process of the support seat 31 and the old brush roller 4a on the base 32 smoother, the telescopic member 312 and the support are symmetrically arranged on the support seat 31. When the support seat 31 slides, the symmetrical telescopic member 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 can quickly and smoothly disengage from the clamping roller mechanism 1.

[0059] Furthermore, if the telescopic member 312 has only one supporting point at the end of the supporting seat 31, the telescopic rod 313 therein will inevitably produce a torsional effect on the supporting point due to gravity when extending, causing the telescopic member 312 to swing up and down. Therefore, a support member R is provided above the opposite end where the support 311 and the supporting seat 31 are fixed. The support member R is connected to the cylinder body of the telescopic member 312 and supports the head position of the telescopic member 312. Thereby, two supporting points are formed for the telescopic member 312, so that the telescopic member 312 can be stably supported during operation, thereby avoiding the telescopic member 312 from swinging up and down.

[0060] like Fig.26 As shown, the supporting seat 31 includes a bottom plate 319 and an end plate W, and the end plates W are symmetrically arranged at both ends of the supporting seat 31 in the length direction thereof. The end plates W are support plates for receiving the axial ends of the old brush roller 4a. A vertical plate 318 symmetrically arranged along the width direction of the supporting seat 31 is provided between the two symmetrical end plates W, and lightening holes K are symmetrically provided on the bottom plate 319 and the vertical plates 318 to reduce the weight of the roller seat; this not only ensures the structural strength of the roller seat, but also reduces the weight of the entire supporting seat 31, and is also easier to slide on the base 32; the bottom plate 319, the end plate W, and the vertical plates 318 constitute a box-type accommodating area that can accommodate the brush roller 4 and is open at the top; thereby, when the old brush roller 4a falls on the supporting seat 31, it can remain horizontally fixed and will not roll or fall out of the supporting seat 31.

[0061] Furthermore, in order 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, and the reinforcing rib plate Q is symmetrically arranged on the inner and outer sides of the box-type accommodating area to form a 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 supporting seat 31, and the L-shaped fixing blocks 314 are limiting members for limiting the brush roller 4 along the length direction of the supporting seat 31; when the old brush roller 4a falls on the supporting seat 31, the L-shaped fixing block 314 clamps it between the two ends of the supporting seat 31 to prevent the old brush roller 4a from rolling and falling off on the supporting seat 31.

[0062] like Fig.18 As shown, in order to enable the supporting seat 31 to quickly stay in place before being connected to the old brush roller 4a, a positioning telescopic member 312 is provided above the base 32. The positioning telescopic member 312 is a cylinder, and a positioning telescopic rod 313 is provided in the cylinder. The head of the positioning telescopic member 312 is connected to the bottom of the supporting seat 31, and can drive the supporting seat 31 to slide along its own length direction and stay in place; and in order to limit the excessive sliding of the positioning telescopic rod 313, a limit seat 317 is provided under the supporting seat 31. When the positioning telescopic rod 313 drives the supporting seat 31 to slide into place along its own length direction, the limit seat 317 abuts against the tail of the cylinder of the positioning telescopic member 312, thereby limiting the supporting seat 31 from continuing to slide.

[0063] Furthermore, in order to prevent the positioning telescopic member 312 from occupying the space of the roller seat, the positioning telescopic member 312 is arranged between the top of the base 32 and the bottom of the supporting seat 31, so that it is covered by the supporting seat 31, and in order to enable the positioning telescopic member 313 and the supporting seat 31 to achieve the effect of quick disassembly and assembly, the head of the positioning telescopic rod 313 is arranged as a T-shaped structure; a T-shaped connecting sleeve 315 is provided at a corresponding position below the supporting seat 31, and the T-shaped structure is plugged into the T-shaped connecting sleeve 315, so that the head of the positioning telescopic member 312 is connected to the supporting seat 31 together; through this plug-in matching design, the connection between the supporting seat 31 and the positioning telescopic member 312 is more convenient and quick, and the effect of easy disassembly and assembly also makes the positioning telescopic member 312 convenient for later maintenance and repair.

[0064] like Figure 17-21 As shown, a walking mechanism 2 that can move forward is provided under the base 32, the walking mechanism 2 remains fixed in the vertical direction, and can move freely relative to the ground in the front and rear directions, the walking mechanism 2 includes a frame-type 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, and the pulley is driven by the motor and the connecting mechanism to drive the walking mechanism 2 to slide on the slide rail a; in order to keep the walking mechanism 2 of the new supporting seat unchanged in direction during travel, a slide rail a is also provided on the ground, the slide rail a separates the new supporting seat from the ground, so that the walking mechanism 2 can move forward more smoothly on the slide rail a, and there is no need to worry about the problem of direction deflection of the new supporting seat.

[0065] like Fig.17 As shown, in order to keep the walking chassis 21 fixed during the unloading roller guiding and clamping roller guiding, a positioning structure is provided between the walking mechanism 2 and the ground, and the positioning structure includes a limit telescopic member 211 and a positioning seat d. The limit telescopic member 211 is arranged on the walking chassis 21 of the walking mechanism 2 and can be extended and retracted up and down. The limit telescopic member 211 is usually a cylinder, and a limit telescopic rod 212 is arranged inside it. The head of the limit telescopic rod 212 is V-shaped. The positioning seat d is fixed on the ground and a V-shaped groove is provided on the top. In the unloading roller guiding and clamping roller guiding steps, when the walking mechanism 2 needs to stop, the head of the limit telescopic rod 212 is stuck in the V-shaped groove to keep the walking mechanism 2 fixed front and back.

[0066] In this embodiment, the unused new brush roller 4b is placed in advance on the supporting seat 31 at the rear; the old brush roller 4a and the new brush roller 4b have the same specifications and sizes. When the two are placed on the supporting seat 31, both ends of them will limit the movement trend in the left and right directions with the L-shaped fixing blocks 314 correspondingly arranged on the supporting seat 31. The only difference is that the old brush roller 4a is an old roller used in the steel plate grinding brushing area s, and the mechanisms for receiving the old brush roller 4a and the new brush roller 4b are the vacant supporting seat 31 on the front side and the rear supporting seat 31 respectively. A telescopic member 312 is provided on the left side of the vacant supporting seat 31. The telescopic member 312 is usually an oil cylinder. A telescopic rod 313 is arranged in the telescopic member 312, and the telescopic rod 313 can be moved along The telescopic rod 313 is extended or retracted in the left and right directions, and is an auxiliary component for the left end of the old brush roller 4a to disengage from the stationary mechanism 102; on the supporting seat 31 on the rear side of which the new brush roller 4b is installed, the telescopic member 313 does not participate in the roller installation process, so the rear supporting seat 31 may not be installed with the telescopic member 31, but in this embodiment, in order to ensure the versatility of the supporting mechanism 2 in the new supporting seat, and to facilitate the maintenance and management of the supporting mechanism 2, the rear supporting seat 31 has the same configuration as the vacant supporting seat 31 on the front side, that is, in this embodiment, the rear supporting seat 31 and the vacant supporting seat 31 on the front side can both receive the old brush roller 4a and the new brush roller 4b, and can work normally even if the positions are swapped.

[0067] like Figure 7-8 As shown, the roller clamping process utilizes the driving element to control the roller clamping mechanism 1 to retract upward, and to move the walking mechanism 2 forward, and then to control the roller clamping mechanism 1 to move downward to the left and right sides of the new brush roller 4b, and then to control the sliding mechanism 101 to retract to the left, so that the right end and the left end of the new brush roller 4b are respectively clamped into the sliding mechanism 101 and the stationary mechanism 102.

[0068] Furthermore, the limiting telescopic member 211 is controlled by a receiving unit (not shown), which may be a sub-controller. When the walking mechanism 2 needs to slide to load the roller, the telescopic rod 313 of the telescopic member 312 on the supporting seat 31 with the old brush roller 4a installed in front is retracted, and a detection element e is provided on the protective tube seat 311 at the side of the telescopic rod 313. By utilizing the contact and 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 walking mechanism 2; when the telescopic rod 313 is retracted, the rod head will trigger 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 causing the walking mechanism 2 to move forward.

[0069] In order to prevent the brush roller 4 from colliding up and down or jumping relative to the supporting seat 31 when it is placed on the supporting seat 31, an elastic supporting mechanism 22 is provided between the upper end of the traveling mechanism 2 and the lower end of the supporting mechanism 3, and at least two elastic supporting mechanisms 22 on the roller seat are symmetrically arranged at the side positions between the traveling mechanism 2 and the supporting mechanism 3 in the left-right direction, so that each position of the supporting mechanism 3 can achieve a buffering effect; the upper and lower ends of the elastic supporting mechanism 22 are respectively hinged to the supporting mechanism 3 and the traveling mechanism 2; and the elastic supporting mechanism 22 is in a compressed state, and the brush roller 4 transmits the gravity to the elastic supporting mechanism 22, thereby generating an upward supporting elastic force on the supporting mechanism 3.

[0070] Specifically, the base 32 and the walking mechanism 2 are both provided with an articulated seat 221, the elastic support mechanism 22 includes a plurality of elastic support cylinders, the elastic support cylinders include earrings 225 articulated on two articulated seats 221, the earrings 325 below the base 32 are locked by nuts 226 and a cylindrical shell 223, a support block 228 is fixed inside the shell 223, the support block 228 and the earrings above the walking chassis 21 are connected by a support rod 227, an elastic member 222 is sleeved on the outer wall of the support rod 227, in order to be able to greatly absorb the impact load generated when the old brush roller 4a is pressed down, the elastic member 222 is usually a plurality of and The disc springs are stacked and close together, and the gravity of the supporting mechanism 3 makes the disc springs tightly stuck between the support block 228 and the strut 227, so that the support block 228 generates an upward pre-tightening force, forming a stable supporting effect on the support chassis 32 and the supporting seat 31; when the old brush roller 4a is placed on the supporting seat 31 in the front, the upper and lower ends of the elastic support cylinder rotate, and 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-absorbing 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 supporting mechanism 3, ensuring that the old brush roller 4a will not jump when it is removed.

[0071] Furthermore, when the old brush roller 4a is placed on the supporting seat 31 in the front, the old brush roller 4a cannot be absolutely placed in the center position of the supporting seat 31, so the supporting mechanism 3 will inevitably produce a slight deflection. If the base 32 and the walking 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 connections, the connection may crack or break. Therefore, the upper and lower ends of the elastic support cylinder are set to be hinged connections, and the hinged design can also form a accommodating and receiving effect on the falling old brush roller 4a, so that the entire supporting mechanism 3 can produce a floating support effect on the old brush roller 4a while protecting the supporting mechanism 3 and the walking mechanism 2 to the greatest extent.

[0072] Going further, Fig.21 As shown, in order to prevent the contact end faces of the support block 228 and the disc spring from wearing out due to frequent contact, a bushing 229 is provided between the support block 228 and the disc spring. When the disc spring and the support block 228 are in contact, the bushing 229 can be a copper sleeve with a relatively low hardness, which can be used as a buffer to prevent the disc spring from directly contacting the support block 228. The worn bushing 229 can also be directly replaced, which avoids the wear problem and saves maintenance costs. In order to minimize the wear caused by the contact between the parts, 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 the wear of the parts of the elastic support cylinder when it is extended or retracted, thereby making the working process of the elastic support cylinder smoother.

[0073] Specifically, if Figure 12-16 As shown, in order to avoid the shaking problem of the supporting mechanism 3 due to the excessive deflection angle, two deflection support mechanisms are symmetrically arranged on the left and right sides above the walking mechanism 2, and the deflection support mechanism includes a cylindrical body 24 and an elastic reset wheel 34, and the elastic reset wheel 34 is connected to the base 32 at the lower end of the supporting mechanism 3; in the outer wall surface of the cylindrical body 24 in the front, back, left and right directions, the left or right wall surface is in an empty state, and on the wall surfaces of the other three directions of the cylindrical body 24, there are corresponding elastic reset wheels 34 against it; when the guide inclined surface 104 is squeezed and matched with the elastic swing wheel 33, the base 32 generates a movement trend in the front and back directions, and drives the elastic reset wheel 34 to generate elastic deformation, which is equivalent to the elastic reset wheel 34 absorbing the excess deflection force and then forming an elastic support effect on the base 32, so that the supporting seat 31 and the brush roller 4 return to a horizontal state again, avoiding the brush roller 4 from tipping over on the supporting mechanism 3.

[0074] Further, if Fig.16As shown, the elastic reset wheel 34 includes a buffer base 346 installed under the base 32, and 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 on the buffer seat 343 by a third pin shaft 342, and an elastic buffer member 345 is provided between the buffer seat 343 and the buffer base 346. When a large external force acts on the rotating wheel 341, in order to enable the elastic buffer member 345 to provide sufficient rebound force, the elastic buffer member 345 is usually a mold spring or a disc spring of a metal material. In addition to providing reverse supporting elastic force for the base 32, the elastic reset wheel 34 can also use the good rebound elasticity of the mold spring or the disc spring to generate elastic force on the base 32 in the front, back, left and right directions, so that the base 32 remains fixed in the front, back, left and right directions, so as to facilitate the installation of the base 31 and the elastic support mechanism 22.

[0075] like Figure 11-28a As shown, the first guide member 35 is arranged on the clamping roller mechanism 1, and the second guide member 107 is arranged on the supporting mechanism 3. The first guide member 35 is a plate member, and the thickness of the first guide member 35 is controlled within a reasonable range of 5mm-10mm, so that the first guide member 35 has sufficient structural strength and the second guide member 107 has sufficient supporting area when in contact with the inclined surface 351. The guide groove 352 is arranged on the first guide member 35 along the thickness direction of the plate member; when the second guide member 107 is squeezed and matched with the inclined surface 351 of the guide groove 352, the inclined surface 351 of the first guide member 35 is subjected to the horizontal force exerted by the second guide member 107, so that the driven mechanism has a horizontal movement tendency and gradually aligns with the active mechanism.

[0076] Specifically, a support portion is provided on the clamping roller mechanism 1, and the support portion is a column fixed on the clamping roller mechanism 1, and the second guide member 107 is a cylindrical member that is sleeved on the support portion and can rotate circumferentially; the sleeved second guide member 107 can be rotated to make the guiding process smoother, and is also convenient for disassembly and assembly with the support portion; in order to allow the second guide member 107 to slide in the guide groove 352, the width of the guide groove 352 is set to be larger than the diameter of the second guide member 107, and the difference between the width of the guide groove 352 and the diameter of the second guide member 107 is in the range of 1mm-3mm; so that after the second guide member enters the guide groove 352, a clearance fit is formed with the guide groove 352, and the guide jamming phenomenon will not occur.

[0077] Further, if Fig.11As shown, the guiding effect of the clamping roller mechanism 1 and the supporting mechanism 3 in the left and right directions is achieved in this way. Since the second guide member 107 can rotate around the supporting part in the circumferential direction, the second guide member 107 is pressed and matched with the inclined surface 351 of the guide groove 352, and the second guide member 107 rotates close to the inclined surface 351, so that the second guide member 107 rolls into the guide groove 352 along the inclined surface 351; compared with the sliding friction force generated by the single extrusion, the rolling friction force generated by the second guide member 107 contacting and extruding the inclined surface is smaller, so that the guiding process of the supporting mechanism 3 in aligning with the clamping roller mechanism 1 is smoother; when the second guide member 107 is pressed and matched with the inclined surface 351 of the guide groove 352, the supporting mechanism 3 moves in the horizontal direction, driving 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; so that before the brush roller 4 falls to the supporting mechanism 3, the brush roller 4 is aligned with the supporting mechanism 3 through the guiding mechanism to avoid interference and collision between the brush roller 4 and the supporting mechanism 3.

[0078] like Fig.11 As shown, due to the error of the equipment itself, this alignment is not absolute, so the supporting mechanism 3 is also required to cooperate with the clamping roller mechanism 1 in the front-to-back direction for guidance. The supporting seat 31 is driven by the positioning telescopic member 322 to keep it aligned with the old brush roller 4a on the clamping roller mechanism 1 in the front-to-back direction, and then guided by the front and rear guide components. Therefore, an elastic swing wheel 33 is arranged on the supporting mechanism 3, and the elastic swing wheel 33 can be elastically deflected back and forth relative to the supporting seat 31; the clamping roller mechanism 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 mechanism 1 carries the old brush roller 4a down to the supporting seat 31, the guide slope 104 is squeezed and matched with the elastic swing wheel 33, so that the elastic swing wheel 33 rotates and elastically deflects, so that the old brush roller 4a on the clamping roller mechanism 1 is aligned front and back with the supporting seat 31.

[0079] like Fig.13 As shown, in order to enable the clamping roller mechanism 1 to continue to slide downward stably after being aligned with the supporting seat 31, guide support plates 105 are symmetrically arranged on the front and rear sides of the clamping roller mechanism 1, and an elastic swing wheel 33 is correspondingly arranged on the base 32 near the guide support plate 105. When the clamping roller mechanism 1 is aligned with the supporting seat 31, the guide support plate 105 contacts the elastic swing wheel 33, providing a stable sliding support point for the clamping roller mechanism 1 to move downward, so that the clamping roller mechanism 1 can move smoothly to the specified position.

[0080] Further, if Figure 23-25As shown, when a conventional guide wheel is used for guiding, it relies on the elastic deformation of the material of the guide wheel itself to perform the guiding function. However, when the guide wheel is subjected to a large extrusion load, the material of the guide wheel itself may be broken. Therefore, in the present embodiment, the guiding of the clamping roller mechanism 1 is mainly achieved by 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 on the rotating base 338 through a second pin shaft 334. The swing assembly includes a swing seat 332. A rotatable guide wheel 331 is hinged on the swing seat 332 through a first pin shaft 333. The guide wheel 331 is usually made of a rubber material with good resilience. In order to enable the guide wheel 331 to rotate and generate elastic compression when it is squeezed by the walking mechanism 1, A connecting shaft 339 is fixed on the swing seat 332, and the gasket 336 and the connecting shaft 339 are connected by bolts. An elastic telescopic part 337 in a compressed state is sleeved on the outer side of the bolt. The elastic telescopic part 337 is usually a mold spring or a disc spring to cope with the larger load generated by the extrusion force; a cross 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 cross 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 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, and the swing angle b is usually 3°-10°.

[0081] like Figure 18-27 As shown, the extended positioning telescopic member 322 is in a no-load exhaust state and no longer controls the sliding process of the supporting seat 31. This is because when the old brush roller 4a falls onto the supporting seat 31, the telescopic member 312 contacts the walking mechanism and drives the supporting seat 31 to disengage to the right. When disengaging, if the positioning telescopic member 323 still maintains a load control state, it will inevitably generate excess interference force on the supporting seat 31, which will have a negative impact on the roller unloading process.

[0082] like Fig.15 As shown, in order to make the clamping roller mechanism 1 move down to align with the left and right sides of the supporting seat 31 and no longer move downward, so as to avoid the situation where the clamping roller mechanism 1 and the supporting seat 31 are misaligned up and down when changing the rollers, a limiting structure is provided between the base 3 and the clamping roller mechanism 1, and 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 be aligned with the supporting seat 31 and is placed on the supporting seat 31, the limiting block 106 and the top column 36 abut against each other, and the end surface area of ​​the block-shaped limiting block 106 that contacts the top column 36 is larger than the area of ​​the upper end surface of the top column 36, so that the limiting block 106 and the top column 36 can fully contact each other to prevent the clamping roller mechanism 1 from continuing to move downward.

[0083] like Figure 18-22 As shown, in order to make the floating support between the base 32 on the supporting mechanism 3 and the walking chassis 21 more stable, at least two chains 231 are connected between the base 32 of the supporting mechanism 3 and the walking chassis 21, and the elastic supporting mechanism 22 generates an upward preload in a compressed state, and the chain 231 remains in a tensioned state under the action of the supporting elastic force generated by the elastic supporting mechanism 22; in the roller unloading step, when the old brush roller 4a is placed on the supporting seat 31, the disc spring in the elastic supporting mechanism 22 is compressed, and the chain 231 switches to a relaxed state, and in the roller loading step, when the new brush roller 4b is separated from the supporting seat 31, the chain 231 switches back to a tensioned state, and through the tightness of the chain 231, it can be better judged whether the brush roller 4 is placed in place on the supporting seat 31.

[0084] Further, if Fig. 22 As shown, the tensioned and relaxed states of the chain 321 are switched instantly under the premise of changes in gravity. By utilizing this characteristic, it can have a control function similar to that of a switch device; that is, at least one switch assembly 23 can be arranged on the traveling chassis of the traveling mechanism 2, and the switch assembly 23 includes a rotating seat 232 and a switch element c; the switch element c is arranged on a bracket 235 beside the rotating seat 232, and in the chains 231 connected between the supporting chassis 32 of the supporting mechanism 3 and the traveling chassis 21 of the traveling mechanism 2, at least one chain 231 is hinged at the bottom of the rotating seat 232; the rotating seat 232 is hinged on the mounting seat 234 of the traveling chassis 21, and the rotating seat 2323 is provided with a forward extending rotating sheet 236, and an elastic member 233 is arranged between the rotating seat 232 and the traveling mechanism 2, and the elastic member 233 can be hooked between the rotating seat 232 and the traveling chassis 2 1 can also be a torsion spring hinged between the rotating seat 232 and the walking chassis 21. During the roller unloading process, when the chain 231 is in a relaxed state, the elastic member 233 will undergo elastic deformation, driving the rotating seat 232 to rotate downward, and sending the action signal to the control unit through the switch element c. The control unit issues an instruction to make the sliding mechanism 101 slide to the right, so that the right end of the old brush roller 4a is disengaged from the sliding mechanism 101, and the remaining roller unloading operations are performed successively. During the roller loading, the state of the chain 231 will not change until the new brush roller 4b is clamped and separated from the supporting seat 31. Therefore, although the supporting mechanism 3 for placing the new brush roller 4b at the rear is configured the same as the supporting mechanism 3 at the front, this is only for consideration of the commonality between the supporting mechanisms 3, and the chain 231 and the switch assembly 23 therein do not participate in the control of the sliding mechanism 101 during the roller loading process again.

[0085] As shown in Figure 8, before the clamping roller mechanism 1 completely leaves the supporting mechanism 3 after clamping the new brush roller 4b, the clamping roller mechanism 1 slowly moves upward with the new brush roller 4b. At this time, the compression amount of the elastic supporting mechanism 22 continues to decrease, and the reset elastic force released makes the supporting seat 31 of the supporting mechanism 3 press upward against the new brush roller 4b, thereby forming a follow-up support for the new brush roller 4b. In other words, the supporting seat 31 is released upward due to the elastic force of the elastic supporting mechanism 22, which will offset part of the gravity of the new brush roller 4b, and play an auxiliary role in the clamping roller mechanism 1 to clamp the new roller 4b, making it more labor-saving for the clamping roller mechanism 1 to clamp the new brush roller 4b.

[0086] Example 2: Fig.28b As shown, the difference between this embodiment and embodiment 1 is that, according to the design considerations of different spatial layouts in the roller changing equipment, the first guide member 35 and the second guide member 107 can be swapped in installation position, the plate-shaped first guide member 35 is connected to the roller clamping mechanism 1, and the cylindrical second guide member 107 is connected to the supporting mechanism 3. The first guide member 35 is installed inverted so that the inclined surface 351 faces the second guide member 107 below. When the roller clamping mechanism 1 moves downward with the first guide member 35, the inclined surface 351 will actively squeeze and cooperate with the second guide member 107. The second guide member 107 is subjected to the horizontal force exerted by the inclined surface 351, so that the supporting mechanism 3 has a horizontal movement trend and gradually aligns with the roller clamping mechanism 1. In this way, the structural design scheme of swapping positions can also achieve the guiding effect in embodiment 1.
