Description

Technical Field

[0001] This invention relates to the field of metal surface treatment technology, and in particular to a brush roller changing machine and its application. Background Technology

[0002] Steel plates, also known as strips, are rolled up and stored after production, commonly known as steel coils. Steel coils are then sent to corresponding product manufacturing plants to be made into corresponding parts according to different usage requirements. During the period between the strip entering the processing plant and being cut, the strip reacts with moisture and chemicals in the air, causing the surface material to peel off or rust. In order to remove the rust layer, the existing technology usually uses brush rollers installed in steel plate grinding equipment to physically grind the surface of the strip. However, this equipment requires the brush rollers to contact the surface of the steel plate during grinding. After long-term use, the grinding effect of the brush rollers will also decrease. Therefore, the brush rollers need to be placed on a roller changing car for replacement with new rollers.

[0003] For example, in the patent for a roller changing vehicle with announcement number CN110842728, the lower end of the working beam is equipped with bearing seat one and bearing seat two, and the working brush roller is installed between the two bearing seats. The working beam and the two bearing seats can be regarded as a roller clamping mechanism, where bearing seat one can be regarded as a sliding seat and bearing seat two can be regarded as a fixed seat. When changing rollers, the base of the roller changing support device extends into the steel plate surface rust removal machine along the roller changing track. The lifting motor drives the lifting mechanism to operate, causing the working beam to descend and the scale-breaking roller to fall on the roller seat of the roller changing support device. At this time, the sliding seat moves outward along the bearing seat slide rail, causing one end of the scale-breaking roller to disengage from the sliding seat. Then, the upper beam is driven to slide, causing the other end of the scale-breaking roller to disengage from the fixed seat. Although this roller changing method can remove the old brush roller, it still has defects.

[0004] After the roller changing car enters the steel plate grinding equipment, it can only passively wait for the sliding seat and the fixed seat to move and disengage from the end of the brush roller in sequence, resulting in low roller changing efficiency.

[0005] The brush roller has roller shafts at both ends, with sliding seats and fixed seats clamping the corresponding roller shafts. Due to error, the brush roller cannot remain perfectly horizontal after being placed on the roller changing trolley. When the sliding seat detaches from one end of the brush roller, the detached end will tilt downwards due to gravity. Since the brush roller is no longer horizontal, when the working beam is driven to move the fixed seat, the roller shaft inside the fixed seat will jam, damaging the brush roller and the fixed seat. Once jamming occurs, manual assistance is required to remove the brush roller, which increases the cost and difficulty of roller changing. At the same time, the roller changing environment inside the steel plate grinding equipment is harsh, often spraying iron filings and sewage, making manual assistance difficult and time-consuming, which also affects the efficiency of roller changing and subsequent steel plate grinding. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the purpose of this invention is to provide a brush roller changing cart. The linkage input unit on the brush roller changing cart can respond to the driving force provided by the sliding seat on the roller clamping mechanism. Through the speed change unit connected between the linkage input unit and the power output unit, the roller seat can switch from the receiving area to the moving buffer area at a speed less than that of the linkage input unit, so as to avoid the brush roller getting stuck and the shaft head deformed when it is removed, thereby reducing the difficulty and cost of changing the roller.

[0007] This leads to the application of a brush roller changing cart, which can be driven into the brush grinding equipment for roller changing. This allows the brush roller to disengage from the clamping mechanism in one go, eliminating the need for manual assistance during roller changing, thus improving roller changing efficiency and the efficiency of subsequent steel plate grinding.

[0008] The technical solution of this invention is implemented as follows:

[0009] A brush roller changing machine includes:

[0010] The base can move along its own length; along the length of the base, there are successively divided into a support area and a movement buffer area.

[0011] The roller seat is set in the receiving area and is slidably connected to the upper end of the base along its own length.

[0012] The speed transmission mechanism is set in the moving buffer area. The speed transmission mechanism includes a linkage input part that can slide along the length direction of the base by pushing or hooking, and a power output part connected to the roller seat. A speed transmission unit is connected between the linkage input part and the power output part so that the sliding speed of the power output part is less than the sliding speed of the linkage input part.

[0013] The linkage input unit can slide in response to external driving force, and through the speed change transmission mechanism, it links the roller seat, so that the roller seat slides from the receiving area to the moving buffer area at a speed less than that of the linkage input unit.

[0014] Preferably, the linkage input part is a vertical plate that is easy to push or hook, and the power output part is a horizontal plate. The vertical plate and the horizontal plate are arranged at intervals in the moving buffer area of ​​the base along the width direction of the base. The speed change unit includes an input rack and an output rack that can slide on the base. A speed change component is connected between the input rack and the output rack. The speed change component includes a rotating shaft that can rotate along its own axis, an input gear and an output gear connected to both ends of the rotating shaft. The outer diameter of the input gear is larger than the outer diameter of the output gear, and the input gear and the output gear mesh with the input rack and the output rack, respectively. The vertical plate is connected to the input rack, and the horizontal plate is connected between the output rack and the roller seat. The cooperation between the vertical plate and the horizontal plate and the gear and rack structure is simple and efficient, which can effectively link the roller seat and reduce the moving speed of the roller seat.

[0015] Preferably, the system also includes a connecting plate that slides along the length of the base, with both the vertical plate and the input rack mounted on the connecting plate. Both the connecting plate and the horizontal plate are slidably connected to the base, allowing the input rack and the output rack to slide along the length of the base. The connecting plate can provide a slidable mounting carrier for the vertical plate and the input rack, allowing the vertical plate to be indirectly connected to the input rack.

[0016] Preferably, along the width direction of the base, the connecting plate extends towards the middle of the base and forms an ear plate. A drive adjustment component is connected to the base and is connected to the ear plate. The drive adjustment component can slide the roller seat through its own extension and retraction to adjust the position of the roller seat in the receiving area. The drive adjustment component can drive the roller seat to slide and adjust the position of the roller seat in the receiving area, making the roller changing process more precise and efficient.

[0017] Preferably, the driving adjustment component is a cylinder, which includes a cylinder body and a telescopic rod that extends and retracts within the cylinder body. The cylinder body is connected to the base, and the telescopic rod is connected to the ear plate. The cylinder can extend and retract quickly, so that the roller seat and the clamping roller mechanism can be quickly aligned.

[0018] Preferably, the cylinder body is directly or indirectly hinged to the base, and the telescopic rod is directly or indirectly hinged to the ear plate; to prevent the telescopic rod from jamming during extension and retraction.

[0019] Preferably, the base is symmetrically provided with a first guide rail extending along the length of the base. The first guide rail passes through the receiving area and the moving buffer area, and the roller seat, connecting plate and cross plate are all slidably connected to the first guide rail. The first guide rail also provides sliding guidance for the roller seat, connecting plate and cross plate. The layout is reasonable and the structure is compact.

[0020] Preferably, a second guide rail corresponding to the ear plate is provided in the middle of the base. The second guide rail is located in the moving buffer area and extends along the length of the base. The ear plate is slidably connected to the second guide rail. The second guide rail provides sliding guidance for the ear plate, so that the connecting plate and the ear plate are connected as a whole have dual guidance, avoiding the torsional effect of the driving adjustment component on the connecting plate when the ear plate is in action.

[0021] Preferably, the roller holder includes a base and support seats at both ends of the base for supporting the ends of the working brush roller. Each support seat includes a receiving surface with its upper end facing the working brush roller. The receiving surface has multiple inwardly recessed mounting holes, each containing a buffer element that protrudes from the receiving surface and can elastically expand and contract. The buffer element can press against the end of the working brush roller and elastically contract within the mounting holes, thus providing elastic cushioning for the working brush roller. This prevents excessive weight of the working brush roller from impacting the support seat, causing deformation of the working brush roller or the support seat, and makes the roller changing process smoother.

[0022] This leads to an application of a brush roller changing machine, comprising the following steps:

[0023] S1: Control the brush roller changing carriage to enter the brush grinding equipment and align the roller seat with the roller clamping mechanism inside the brush grinding equipment;

[0024] S2: Control the clamping roller mechanism to descend along the initial position and place the working brush roller on the roller seat. Then control the sliding seat to slide away from the end of the working brush roller. The roller seat is linked to slide from the receiving area to the moving buffer area through the speed transmission mechanism, so that the sliding seat and the fixed seat are disengaged from both ends of the working brush roller.

[0025] S3: Raise the clamping roller mechanism, and then control the roller changing car and the working brush roller 4 placed on the roller changing car to drive out of the brushing equipment in the opposite direction.

[0026] Preferably, there are two more steps before step S1:

[0027] S1a: Arrange two brush roller changing carriages side by side on the upper end of a traveling mechanism that can move back and forth; and place a new working brush roller on the roller seat of the rear brush roller changing carriage;

[0028] S1b: Control the traveling mechanism to travel in the front-to-back direction to the predetermined roller changing position, so that the unloaded brush roller changing trolley on the front side is aligned with the brush grinding equipment.

[0029] After step S3, there are three more steps:

[0030] S4: Control the traveling mechanism to travel in the front-back direction so that the brush roller changing car on the rear side is aligned with the brush grinding equipment. Then control the brush roller changing car on the rear side loaded with the new working brush roller to drive into the brush grinding equipment in the left-right direction and align the roller seat and the new working brush roller on the roller seat with the clamping roller mechanism.

[0031] S5; Lower the clamping roller mechanism to align the sliding seat and the fixed seat with the corresponding ends of the new working brush roller. Then control the sliding seat to slide in the direction close to the end of the new working brush roller so that the sliding seat and the end of the new working brush roller are in place. After that, continue to slide the sliding seat in the direction close to the end of the new working brush roller and drive the roller seat to slide so that the other end of the new working brush roller is in place with the fixed seat.

[0032] S6: The control clamping mechanism holding the new working brush roller returns to its initial position; the two side-by-side brush roller changing carriages eliminate the time required to load the new working brush roller onto the roller holder, allowing the new working brush roller to be quickly replaced onto the clamping mechanism after the working brush roller is removed, further improving the efficiency of roller changing.

[0033] The beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0034] This invention provides a brush roller changing machine and its application, which, compared with the prior art:

[0035] 1. When the brush roller changing trolley enters the brush grinding equipment, the sliding seat can provide driving force to the linkage input unit when it disengages from the end of the brush roller. This allows the roller seat to move synchronously with the falling working brush roller and the sliding seat, and switch from the receiving area on the base to the moving buffer area. This allows both ends of the working brush roller to disengage from the clamping roller mechanism together, preventing the shaft end of the working brush roller from deforming due to the tilt of the working brush roller, and improving the efficiency of roller changing.

[0036] 2. Both ends of the working brush roller disengage from the clamping roller mechanism at the same time, so that there is no jamming between the working brush roller and the clamping roller mechanism. Therefore, no manual assistance is required for roller replacement, which further improves the efficiency of roller replacement and reduces the cost of roller replacement.

Detailed Implementation

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The specific implementation of this invention is as follows:

[0054] like Figure 1-6 As shown, the present invention provides a brush roller changing cart, comprising:

[0055] The base 23 can move along its own length; along the length of the base 23, the base 23 is divided into a receiving area 231 and a moving buffer area 232.

[0056] Roller seat 21a is disposed within the receiving area 231, and roller seat 21a is slidably connected to the upper end of base 23 along its own length direction;

[0057] The speed transmission mechanism 25 is disposed in the moving buffer area 232. The speed transmission mechanism 25 includes a linkage input part that can slide along the length direction of the base 23 by pushing or hooking, and a power output part connected to the roller seat 21a. A speed transmission unit is connected between the linkage input part and the power output part so that the sliding speed of the power output part is less than the sliding speed of the linkage input part.

[0058] The linkage input unit can slide in response to external driving force, and through the speed transmission mechanism 25, it links the roller seat 21a, causing the roller seat 21a to slide from the receiving area 231 to the moving buffer area 232 at a speed less than that of the linkage input unit.

[0059] Furthermore, the brush roller changing cart can change rollers inside the steel plate grinding brush equipment. The grinding brush equipment has a roller clamping mechanism 1, which includes a sliding seat 13 and a fixed seat 11 that clamp the two ends of the working brush roller 4. The specific structure and principle of the roller clamping mechanism 1 can be found in the roller changing cart patent with announcement number CN110842728, and will not be repeated here.

[0060] Furthermore, the steel plate grinding equipment is pre-installed with a track 15, and rollers 33 are arranged on both sides of the base 23. A roller shaft 32 is connected between the two rollers 33. The roller shaft 32 is driven by a power mechanism 3, which includes a motor 31. The motor is connected to a transmission device, and the transmission device is transmitted to the roller shaft 32 through a chain 34. The power mechanism 3 can drive the rollers 33 to rotate on the track 15, so that the base 23 moves forward or backward along its own length. For its specific structure, please refer to the roller changing car patent CN110842728, which will not be described in detail here.

[0061] Furthermore, such as Figure 8-11As shown, the linkage input part is a vertical plate 24 that is easy to push or hook, and the power output part is a horizontal plate 258. The vertical plate 24 and the horizontal plate 258 are arranged at intervals in the moving buffer area 232 of the base 23 along the width direction of the base 23. The transmission unit includes an input rack 251 and an output rack 255 that can slide on the base 23. A transmission component is connected between the input rack 251 and the output rack 255. The transmission component includes a rotating shaft 252 that can rotate along its own axis, an input gear 253 and an output gear 254 connected to both ends of the rotating shaft 252. Wheel 254 and shaft 252 are connected to a rotating support 256; the outer diameter of input gear 253 is larger than the outer diameter of output gear 254, and input gear 253 and output gear 254 mesh with input rack 251 and output rack 255 respectively; vertical plate 24 is connected to input rack 251, and horizontal plate 258 is connected between output rack 255 and roller seat 21a; the cooperation between vertical plate 24 and horizontal plate 258 and gear rack structure is simple and efficient, which can effectively link roller seat 21a and reduce the moving speed of roller seat 21a.

[0062] Furthermore, as is well known, for a rotating part, the linear velocity is equal to the product of the angular velocity and the radius of the part. In the speed transmission mechanism 25, the input gear 253 and the output gear 254 are connected to the same rotating shaft 252, so their angular velocities are the same. Then, the radii of the input gear 253 and the output gear 254 are made different to produce a differential transmission effect, thereby achieving the linkage and differential effect between the vertical plate 24 and the roller seat 21a.

[0063] Furthermore, considering the actual speed ratio of the input gear 253 and the output gear 254, the ratio of the outer diameter of the output gear 254 to the outer diameter of the input gear 253 is in the range of 1:4 to 1:2; this ratio range can make the linkage speed of the sliding seat 13 to the roller seat 21a moderate, making the roller changing process smoother.

[0064] Furthermore, such as Figure 11 As shown, the rotating support 256 provides a mounting carrier and rotational support for the rotating shaft 252. The rotating support 256 includes a support 256b and a rotating connecting seat 256a connected to the support 256b. The support 256b is mounted on the base 23, and the rotating shaft 252 is rotatably connected to the rotating connecting seat 256a along its own axis.

[0065] Furthermore, the rotating connecting seat 256a is provided with a central hole a that connects the two sides of the rotating connecting seat 256a. The rotating shaft 252 is rotatably connected in the central hole a along its own axis, and the outer diameters of the input gear 253 and the output gear 254 are both larger than the outer diameter of the rotating shaft 252. In order to facilitate the installation and adjustment of the speed ratio of the input gear 253 and the output gear 254, at least one of the input gear 253 and the output gear 254 is detachably connected to the rotating shaft 252, so that at least one end of the rotating shaft 252 can pass through the central hole a and be installed on the rotating connecting seat 256a.

[0066] Furthermore, the input gear 253 has a large outer diameter and a large mass. If it were integrally molded onto the rotating shaft 252, installation would be difficult. Moreover, the large-diameter input gear 253 is expensive, and if it is damaged, the entire rotating shaft 252 and the input gear 253 would need to be replaced together. Therefore, in this mechanism, the input gear 253 is detachably connected to the rotating shaft 252, while the output gear 254 is integrally molded with the rotating shaft 252. This facilitates the disassembly and replacement of the input gear 252 and reduces the maintenance cost of the mechanism.

[0067] Furthermore, in order to make the rotation of the shaft 252 smoother, the rotating connecting seat 256a is a cylindrical structure with open ends, and the rotating connecting seat 256a has symmetrical mating holes b at both ends inside, the diameter of the mating hole b is larger than the diameter of the central hole a; an axially fixed bearing 2561 is installed in the mating hole b, and the shaft 252 passes through the bearing 2561.

[0068] Furthermore, the axial positioning of bearing 2561 is achieved as follows: bearing 2561 includes an inner ring 2561b and an outer ring 2561a; both ends of the rotating connecting seat 256a are connected to end caps 2562 that seal the openings of the rotating connecting seat 256a, and the end caps 2562 seal the openings to prevent dust; the inner side of the outer ring 2561a is tightly against the bottom of the mating hole b, and the outer side of the outer ring 2561a is abutted by the end caps 2562, thereby restricting the axial movement of bearing 2561.

[0069] Furthermore, the axial positioning of the input gear 253 is achieved as follows: an axial positioning assembly is also installed on one end of the shaft 252 that connects to the input gear 253. The axial positioning assembly includes a pressure plate 2564 and a spacer 2563 connected to the outer wall of the shaft 252. The spacer 2563 abuts against the inner end face of the input gear 253. The pressure plate 2564 is connected to the corresponding end of the shaft 252 by screws and abuts against the outer end face of the input gear 253, so that the input gear 253 remains axially fixed.

[0070] Furthermore, the axial positioning of the rotating shaft 252 is achieved as follows: the rotating shaft 252 includes a body 2521 and a connecting section 2522 connected to one end of the body 2521. The outer diameter of the connecting section 2522 is larger than the outer diameter of the body 2521. The output gear 254 is integrally formed on the outer end of the connecting section 2522. The inner end face of the connecting section 2522 abuts against the inner ring 2561b of the bearing near the output gear 254. The opposite end of the spacer 2563 that abuts against the input gear 253 passes through the end cover 2562 and abuts against the inner ring 2561b of the bearing near the input gear 253, thereby restricting the axial movement of the rotating shaft 252. By using the connecting end 2522 at one end of the rotating shaft 252 to abut against the inner ring 2561b of the bearing, and the spacer 2563 at the other end of the rotating shaft 252 to abut against both the inner ring 2561b of the bearing and the input gear 253, the axial positioning of the input gear 253 and the rotating shaft 252 is achieved. The structure is simple and the design is ingenious.

[0071] like Figure 8-9 As shown, the input rack 251 and output rack 255 need to slide along the length of the base 23. However, directly sliding the two racks onto the base 23 would cause wear between the racks and the base 23, affecting the accuracy and structural strength of the racks. Therefore, the base 23 has a connecting plate 257 and a horizontal plate 258 that slide along the length of the roller seat 21a. The input rack 251 and the vertical plate 24 are both connected to the connecting plate 257, and the output rack 255 is connected to the horizontal plate 258. The connecting plate 257 and the horizontal plate 258 are both slidably connected to the base 23, allowing the input rack 251 and output rack 255 to slide along the length of the base 23. The connecting plate 257 can provide a sliding mounting carrier for the vertical plate 24 and the input rack 251, allowing the vertical plate 24 and the input rack 255 to slide together. 51. Indirect connection; when the vertical plate 24 responds to the pushing or hooking driving force provided by the sliding seat 13, the connecting plate 257 drives the input rack 251 to slide and drives the rotating shaft 252 to rotate, thereby causing the horizontal plate 258 to drive the output rack 255 to slide in the same direction as the input rack 251 at a second speed less than the first speed; the connecting plate 257 is the mounting carrier of the input rack 251 and the second linkage component, and the horizontal plate 258 is the mounting carrier of the output rack 255, and also the intermediate carrier connecting the output rack 255 and the roller seat 21a; both the connecting plate 257 and the horizontal plate 258 are slidably connected to the base 23, which can not only ensure the linkage effect of the sliding seat 13 on the roller seat 21a, but also provide support for the corresponding rack, without the need for the two racks to be directly slidably connected to the base 23.

[0072] Furthermore, such as Figure 9As shown, the base 23 is a frame structure consisting of two long horizontal beams and two short vertical beams. The base 23 is symmetrically provided with a first guide rail 28 extending along the length of the base 23. The roller seat 21a, ear plate 257, and flat plate 258 are all slidably connected to the first guide rail 28. The first guide rail 28 can provide sliding guidance for each sliding component. The layout is reasonable and the structure is compact.

[0073] Furthermore, after the roller changing carriage 2 enters the brush grinding equipment, the roller seat 21a may experience positional deviation, causing the roller seat 21a to fail to align with the roller clamping mechanism 1. Therefore, along the width direction of the roller seat 21a, the connecting plate 257 has an ear plate 259 extending towards the middle of the base 23. A drive adjustment component is connected to the base 23, and the drive adjustment component is connected to the ear plate 259. The drive adjustment component extends and retracts through the ear plate 259 and triggers the speed transmission mechanism 25 to drive the roller seat 21a to slide along its own length direction, so that the roller seat 21a aligns with the roller clamping mechanism 1. The drive adjustment component can drive the roller seat to slide and adjust the position of the roller seat in the receiving area, making the roller changing process more precise and efficient.

[0074] Furthermore, the ear plate 259 extending towards the middle of the base 23 forms a lever arm. Therefore, when the driving adjustment component acts on the ear plate 259, it will generate a torque on the connecting plate 257, which can easily cause the connecting plate 257 to jam with the first guide rail 28. To avoid this phenomenon, a second guide rail 27 corresponding to the ear plate 259 is provided in the middle of the base 23. The second guide rail 27 is located in the moving buffer area 232 and extends along the length of the base 23. The ear plate 259 is slidably connected to the second guide rail 27. The second guide rail 27 can provide sliding guidance for the ear plate 259, so that the connecting plate 257 and the ear plate 259, which are connected as a whole, have dual guidance and will not cause sliding jamming due to torsion.

[0075] Furthermore, such as Figure 9 As shown, to ensure roller changing efficiency, the driving adjustment component is a cylinder 26. The cylinder 26 includes a cylinder body 261 and a telescopic rod 262 that extends and retracts within the cylinder body 261. The cylinder body 261 is connected to the base 23, and the telescopic rod 262 is connected to the ear plate 259. The telescopic rod 262 extends and retracts within the cylinder body 261 and acts on the ear plate 259 to drive the roller seat 21a to slide along its own length until the roller seat 21a is vertically aligned with the roller clamping mechanism 1. The cylinder 26 can extend and retract quickly to quickly align the roller seat 21a with the roller clamping mechanism 1.

[0076] Furthermore, the cylinder body 261 is hinged to the base 23, and the telescopic rod 262 is hinged to the ear plate 259. The hinge can be direct or indirect. In this embodiment, the cylinder body 261 and the telescopic rod 262 are indirectly hinged. The base 23 is provided with a hinge seat 263, and a pin 263 passes through the cylinder body 262 and the hinge seat 263 to achieve the hinge. The ear plate 259 is connected to a corresponding rotating connecting seat, and the head of the telescopic rod 261 is hinged to the rotating connecting seat. When the telescopic rod 262 extends or retracts within the cylinder body 261, the cylinder body 261 and the telescopic rod 262 rotate to prevent the telescopic rod 262 from jamming during extension or retraction.

[0077] Furthermore, such as Figure 9 , Figure 12 As shown, the roller seat 21a includes a base 29 and support seats 21 at both ends of the base 29 for supporting the ends of the working brush roller 4. The support seat 21 includes a support surface 211 with its upper end facing the working brush roller 4. The support surface 211 is provided with a plurality of inwardly recessed mounting holes 218. The mounting holes 218 have buffer members 213 that protrude from the support surface 211 and can elastically expand and contract. The buffer members 213 abut against the end of the working brush roller 4 and generate elastic contraction within the mounting holes 218, thereby forming an elastic buffer for the working brush roller 4. This prevents the working brush roller 4 from impacting the support seat 21 due to excessive weight, causing deformation of the working brush roller 4 or the support seat 21, and making the roller changing process smoother.

[0078] Specifically, the elastic expansion and contraction of the buffer 213 is achieved as follows: the supporting surface 211 is arc-shaped, and along the arc-shaped extension direction, multiple mounting holes 218 are evenly distributed on the supporting surface 211, penetrating the support seat 21 in a direction perpendicular to the supporting surface 211. Each mounting hole 218 includes a large-diameter section 218a and a small-diameter section 218b that open downwards sequentially. A stepped surface 215 is formed at the junction of the large-diameter section 218a and the small-diameter section 218b. The outer diameter of the buffer 213 is... The outer diameter of the small diameter section 218b is matched; multiple disc springs 214 are sleeved on the buffer member 213, and one end of the buffer member 213 is connected to the cap body 212. The top of the cap body 212 protrudes upward from the support surface 211, and the multiple disc springs 214 are located between the bottom end of the cap body 212 and the step surface 215; when the specifications or weight of the working brush roller 4 are changed, the buffering force formed by the buffer member 213 on the working brush roller 4 can be changed by removing and installing the number of disc springs 214 sleeved on the buffer member 213.

[0079] Furthermore, the other end of the buffer 213 protrudes through the through hole 218b, and the column of the buffer 213 protruding through the through hole 218b has a threaded section. In order to prevent the buffer 213 from coming out of the mounting hole 218, a first nut 216 is threadedly connected to the threaded section, and the first nut 216 abuts against the lower end of the support 21.

[0080] Furthermore, in addition to restricting the buffer 213, the first nut 216 can also make slight adjustments to the elasticity of the buffer 213. That is, by rotating the first nut 216, the length of the cap 212 protruding from the support surface 211 is changed, thereby adjusting the elasticity generated by the multiple disc springs 214.

[0081] Furthermore, when the working brush roller 4 is not in contact with the work roller, the first nut 216 abuts against the lower end of the support seat 21 and puts the multiple disc springs 214 in an elastic compression state, thereby providing elastic preload to the buffer 213.

[0082] Furthermore, the buffer member 213 is threadedly connected to a second nut 216a on its column body that protrudes from the through hole 218b. The end face of the second nut 216a abuts against the first nut 216 to prevent the first nut 216 from loosening. The first nut 216 and the second nut 216a form an opposing nut structure, thereby playing an anti-loosening role.

[0083] Furthermore, in order to have a transverse through hole on the threaded section near the second nut 216a, a cotter pin 217 is installed in the through hole to restrict the loosening of the second nut 216a; the cotter pin 217 can prevent the second nut 216a from loosening while preventing the second nut 216a from coming out of the threaded section.

[0084] Furthermore, the cap body 212 and the buffer component 213 are integrally formed; the integral forming method has good structural strength and is easy to assemble.

[0085] Furthermore, considering the range of variations in the specifications and weight of the working brush roller 4 in actual use, the number of disc springs 214 fitted on the buffer 213 ranges from 6 to 10.

[0086] like Figure 1-7 As shown, an application of a brush roller changing cart is provided, including the following steps:

[0087] S1: Control the brush roller changing carriage to enter the brush grinding equipment and align the roller seat 21a with the roller clamping mechanism 1 inside the brush grinding equipment;

[0088] S2: Control the clamping roller mechanism 1 to descend along the initial position and place the working brush roller 4 on the roller seat 21a. Then control the sliding seat 13 to slide in a direction away from the end of the working brush roller 4. And through the speed transmission mechanism 25, the roller seat 21a is linked to slide from the receiving area 231 to the moving buffer area 232, thereby causing the sliding seat 13 and the fixed seat 11 to disengage from both ends of the working brush roller 4.

[0089] S3: Raise the clamping roller mechanism 1, and then control the roller changing car and the working brush roller 4 placed on the roller changing car to drive out of the brushing equipment in the opposite direction.

[0090] Furthermore, the two ends of the working brush roller 4 are connected to the fixed seat 11 and the sliding seat 13 through a toothed structure. Taking the sliding seat 13 as an example, the sliding seat 13 is provided with an internal gear, and the end of the working brush roller 4 is provided with an external gear. The internal gear has long teeth and short teeth. For its specific structure, please refer to the gear meshing structure patent with announcement number CN211103283, which will not be described in detail here. Specifically, when the sliding seat 13 slides at a first speed, the roller seat 21a will slide in the same direction as the sliding seat 13 at a second speed less than the first speed. Therefore, when the sliding seat 13 slides and gradually disengages from one end of the working brush roller 4, The roller seat 21a also slides along with the working brush roller 4 and gradually disengages from the fixed seat 13. The disengagement process is carried out simultaneously. Since the sliding speed of the sliding seat 13 is fast and the sliding speed of the roller seat 21a is slow, the external gear on the sliding seat 13 disengages from the internal gear at one end of the working brush roller 4 first. At this time, most of the external gear at the other end of the working brush roller 4 has disengaged from the internal gear on the fixed seat 13. Therefore, the roller shaft of the working brush roller 4 will not deform. At this time, it is only necessary to continue to control the movement of the sliding seat 13, and the roller seat 21a and the working brush roller 4 on the roller seat 21a will disengage from the fixed seat 13, thereby realizing the unloading of the roller.

[0091] Furthermore, to improve roll changing efficiency, there are two additional steps before step S1:

[0092] S1a: Arrange two brush roller changing carriages side by side on the upper end of a traveling mechanism that can move back and forth; and place a new working brush roller 4a on the roller seat 21a of the rear brush roller changing carriage;

[0093] S1b: Control the traveling mechanism to travel in the front-to-back direction to the predetermined roller changing position, so that the unloaded brush roller changing trolley on the front side is aligned with the brush grinding equipment.

[0094] Before step S1, there are two more steps:

[0095] S1a: Arrange two brush roller changing carriages side by side on the upper end of a traveling mechanism that can move back and forth; and place a new working brush roller 4a on the roller seat 21a of the rear brush roller changing carriage;

[0096] S1b: Control the traveling mechanism to travel in the front-to-back direction to the predetermined roller changing position, so that the unloaded brush roller changing trolley on the front side is aligned with the brush grinding equipment.

[0097] After step S3, there are three more steps:

[0098] S4: Control the traveling mechanism to travel in the front-back direction so that the brush roller changing car on the rear side is aligned with the brush grinding equipment. Then control the brush roller changing car loaded with the new working brush roller 4a on the rear side to drive into the brush grinding equipment in the left-right direction and align the roller seat 21a and the new working brush roller 4a on the roller seat 21a with the clamping roller mechanism 1.

[0099] S5; Lower the clamping roller mechanism 1 so that the sliding seat 13 and the fixed seat 11 are aligned with the corresponding ends of the new working brush roller 4a. Then control the sliding seat 13 to slide in the direction close to the end of the new working brush roller 4a so that the sliding seat 13 and the end of the new working brush roller 4a are in place. Then, make the sliding seat 13 continue to slide in the direction close to the end of the new working brush roller 4a and drive the roller seat 21a to slide so that the other end of the new working brush roller 4a is in place with the fixed seat 11.

[0100] S6: The control clamping mechanism 1 holding the new working brush roller 4a is reset upward to the initial position; the two side-by-side brush roller changing carriages eliminate the time of loading the new working brush roller 4a on the roller seat 21a, so that after the working brush roller 4 is replaced, the new working brush roller 4a can be quickly replaced on the clamping mechanism 1, further improving the efficiency of roller changing.

[0101] Furthermore, such as Figure 1-7 As shown, the base 23 cannot move when unloading or replacing the roller, otherwise the roller seat 21a will shift. Therefore, the fixed seat 11 has a first limiting plate 12, and the base 23 has a second limiting plate 22. When the roller clamping mechanism 1 moves down from the initial working position, the first limiting plate 12 is on the side of the second limiting plate 22 facing the roller seat 21a. The first limiting plate 12 and the second limiting plate 22 are intersected and form a hooking action, so that the base 23 stays in the predetermined position to restrict the base 23 from moving backward out of the working brush roller 4 brushing device. When the roller clamping mechanism 1 moves up, the first limiting plate 12 and the second limiting plate 22 separate and are unlocked, so that the base 23 can move backward out of the working brush roller 4 brushing device. The intersecting first limiting plate 12 and second limiting plate 22 have a simple structure. When unloading the roller, the two can quickly form a hooking action to restrict the sliding of the base 23. After the roller is unloaded, the two can also quickly separate.

[0102] Furthermore, the sliding seat 13 has a hanging plate 14, which is used to provide driving force for the upright plate 24. When the clamping roller mechanism 1 moves down along the initial working position, the hanging plate 14 is on the side of the upright plate 24 facing the roller seat 21a, so that the hanging plate 14 and the upright plate 24 are staggered and form a hooking action on the upright plate 24, so that the sliding seat 13 can slide with the second linkage in a direction away from the working brush roller 4. When the clamping roller mechanism 1 moves up, the hanging plate 14 and the upright plate 24 separate to release the linkage. The structure of the staggered hanging plate 14 and the upright plate 24 is simple. When unloading the roller, the two can quickly form a hooking action and link together. After unloading the roller, the two can also quickly separate.

[0103] 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.
