Description

Technical Field

[0001] This invention relates to the field of rubber roller surface polishing technology, specifically to a device and working method for polishing the surface of rubber rollers for spinning machines. Background Technology

[0002] Textile machine rubber rollers are key components with a metal core and an outer layer of elastic rubber. Their core function is to hold, stretch, transport, and control yarn or fiber, playing a crucial role in the uniformity, strength, and surface quality of textiles. During spinning, the rubber surface holds and stretches the yarn for a long time, causing the rubber layer to suffer from the following problems: surface wear and non-roundness; hardening and loss of elasticity; grooves and excessive bounce. Therefore, rubber grinding is to repair these problems and restore its roundness and smoothness.

[0003] The core of textile rubber roller polishing is graded grinding and ensuring concentricity and roughness. To ensure that the polishing effect meets industrial requirements, multiple process steps are required, such as: coarse grinding, cleaning brush surface to remove impurities, fine grinding, and dust removal roller to remove impurities again. However, the rubber rollers need to be frequently replaced during each coarse and fine grinding, which makes the rubber roller polishing process cumbersome and the working time too long. At the same time, the above operations need to be done manually, which is not only time-consuming and labor-intensive, resulting in poor work efficiency, but also increases the danger of this work. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device and method for grinding the surface of rubber rollers on spinning machines, which solves the problem that each rubber roller needs to be frequently replaced during coarse and fine grinding, resulting in a cumbersome rubber roller grinding process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a surface grinding device for a spinning machine rubber roller, comprising a worktable, on which a coarse grinding mechanism and a fine grinding mechanism for grinding the surface of the rubber roller are provided; further comprising: a switching component, the switching component comprising a switching shaft, a rotating rod slidably disposed on the switching shaft, and a clamping sleeve fixedly connected to the rotating rod, the clamping sleeve initially clamping the rubber roller; a dust-adhesive component, the dust-adhesive component comprising an arc-shaped panel, on which a dust-adhesive tape is disposed with its back attached, the rubber roller automatically rolling to remove dust when rotating on the arc-shaped panel; and a rubber-changing component, the rubber-changing component being responsible for changing the usage area of ​​the dust-adhesive tape at a set time. The system includes a replacement component; a roller removal component, which includes a pair of guide rods. When the pair of rotating rods rotate to the corresponding guide rods, they move away from each other, causing the polished rubber roller to fall off; a roller loading component, which includes a pair of hydraulic rods mounted on the worktable. The pair of hydraulic rods extend for a set time, causing a pair of clamping sleeves to come together, thus clamping the rubber roller; and a cleaning component, which includes a cleaning brush, responsible for cleaning surface impurities from the rough-polished rubber roller. The worktable is arranged in a circumferential path with a rough polishing area, a cleaning area, a fine polishing area, a dust-adhesive area, and a replacement area that the rubber roller needs to pass through in sequence, so that the rubber roller can complete all the polishing work and automatically load and unload.

[0006] Preferably, the switching component further includes a drive motor, the output end of which is fixedly connected to a drive shaft, the drive shaft being fixedly connected to the switching shaft, the bottom of which is provided with a first motor base fixedly connected to the top surface of the workbench, a limit strip being fixedly connected to the drive shaft, and a slot being provided on the rotating rod, the rotating rod being slidably connected to the limit strip through the slot.

[0007] Preferably, the adhesive tape includes an adhesive area and a non-adhesive area, and a shaping plate is fixedly connected to the curved panel to limit the non-adhesive area. The shaping plate ensures that the back of the adhesive tape is always in contact with the inner curved surface of the curved panel when it slides on the curved panel.

[0008] Preferably, the coarse grinding mechanism includes a first electric guide rail, a first slider sliding on the first electric guide rail, and a coarse grinding machine fixedly connected to the first slider; the fine grinding mechanism includes a second electric guide rail, a second slider sliding on the second electric guide rail, and a fine grinding machine fixedly connected to the second slider; a touch switch is provided on the worktable, and the touch switch is electrically connected to a controller.

[0009] Preferably, the adhesive changing component includes a feeding roller and a take-up roller. A stepper motor is fixedly connected to the end of the take-up roller, and a support frame is rotatably connected to the end of the feeding roller. The two ends of the adhesive tape are respectively wrapped around the outer walls of the feeding roller and the take-up roller. The stepper motor is electrically connected to the controller.

[0010] Preferably, the guide rod includes an inclined surface and a flat surface, and a U-shaped plate is fixedly connected to the bottom of the guide rod. The U-shaped plate is fixedly connected to the workbench. When the rotating rod rotates downward and touches the inclined surface, it moves outward passively. A first ramp plate for unloading is provided below the workbench.

[0011] Preferably, the roller loading component includes a second ramp plate for feeding material, the second ramp plate is provided with a parallel section and a sloping section for storing at least one rubber roller during operation, and an arc-shaped baffle is fixedly connected to the end of the second ramp plate.

[0012] Preferably, a buffer component is provided at the end of the first ramp slab. The buffer component includes a brake plate, a damping rod fixedly connected to the brake plate, and a buffer plate fixedly connected to the damping rod. A pressure sensor is provided on the brake plate.

[0013] Preferably, both the coarse grinding mechanism and the fine grinding mechanism include a geared motor and a second motor base fixedly connected to the bottom of the geared motor. The output end of the geared motor is fixedly connected to a linkage shaft. The end of the linkage shaft is provided with multiple drive rods. The end of each drive rod is provided with an electromagnet and an elastic element. The end of the rubber roller is provided with a drive groove adapted to the drive rod.

[0014] A method for operating a surface grinding and repair device for a spinning machine rubber roller, applied to the aforementioned surface grinding and repair device for a spinning machine rubber roller, comprises the following steps:

[0015] The first electric guide rail, the second electric guide rail, the geared motor, the coarse grinding machine and the fine grinding machine are turned on in sequence to start coarse grinding of the new rubber roller and fine grinding of the rubber roller that has been coarsely ground.

[0016] After the fine grinding mill contacts the touch switch, the stepper motor starts to rotate the take-up roller to replace the dust-adhesive belt in the usage area;

[0017] After the rubber roller finishes adhering to the dust, it touches the guide rod, causing a pair of rotating rods to separate, and the rubber roller that has finished adhering to the dust will fall automatically.

[0018] When the rubber roller rolls to the end on the first ramp, it squeezes the pressure sensor, causing the hydraulic rod to start and, through the rotating rod, to put the rotating sleeve into the end of the new rubber roller;

[0019] The drive motor rotates the four rubber rollers, which on the one hand realizes the switching of each rubber roller zone, and on the other hand, it rotates the new rubber roller to the coarse grinding zone. Under the action of the elastic element, the drive rod enters the drive groove, and the reduction motor starts to drive the new rubber roller to rotate and perform coarse grinding. This process is repeated.

[0020] This invention provides a device and method for grinding the surface of rubber rollers in spinning machines. It offers the following advantages:

[0021] 1. This invention, by setting a switching component, uses a rotating rod and a clamping sleeve to rotate the rubber rollers, so that each rubber roller can pass through the coarse grinding area, cleaning area, fine grinding area, dust accumulation area and replacement area in sequence along a circumferential path, so that different rubber rollers can perform different tasks at the same time, saving time and improving work efficiency.

[0022] 2. This invention, by setting up an arc panel, a dust-adhesive tape, and a shaping plate, uses a blank dust-adhesive tape roll, which can be shaped by the shaping plate to keep it in an arc shape. This is beneficial for the rubber roller to roll and adhere to dust, thus automatically completing the final dust-adhesive work of the rubber roller when the rubber roller exchange work area is reached, saving time and effort.

[0023] 3. This invention replaces the entire usable area of ​​the adhesive tape by setting a touch switch and a take-up roller, with a stepper motor controlling the number of rotations of the take-up roller. This ensures that the adhesive area on the arc panel is fresh every time a new adhesive roller is used for dust removal. Moreover, the adhesive area replacement time is just right, occurring after the fine grinding machine has finished grinding the adhesive roller. This is because the fine grinding process contaminates the adhesive area, and replacing the adhesive at this time ensures that the adhesive area remains clean.

[0024] 4. This invention achieves automatic detachment of rubber rollers by setting up roller disassembly and roller loading components, using only guide rods. Through the cooperation of hydraulic rods and pressure sensors, a new rubber roller is automatically loaded for each falling rubber roller, and the front and rear working connections are tight. Furthermore, through the structural design of the second ramp plate, it is ensured that the rubber roller to be ground can be automatically replenished under the action of gravity, and even if the rubber roller rotates, it will not be affected.

[0025] 5. This invention allows for free switching between the five working areas of the entire device by setting up touch switches, pressure sensors, and electromagnets, without human intervention. When performing multiple operations on the rubber rollers, the switching is carried out in an orderly manner according to its own logic, and the working areas do not interfere with each other. This enables multiple rubber rollers to automatically complete feeding, coarse grinding, cleaning, fine grinding, dust removal, and unloading, resulting in a high degree of automation and making it faster and more convenient to use.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see the appendix Figure 1 -Appendix Figure 5This invention provides a device for grinding the surface of a spinning machine rubber roller, including a worktable 1, on which a coarse grinding mechanism 2 and a fine grinding mechanism 3 are provided for grinding the surface of the rubber roller. It also includes: a switching component 4, which includes a switching shaft 41, a rotating rod 42 slidably disposed on the switching shaft 41, and a clamping sleeve 43 fixedly connected to the rotating rod 42, the clamping sleeve 43 initially clamping the rubber roller; a dust-adhesive component 5, which includes an arc panel 51, on which a dust-adhesive tape 52 is disposed, the back of which adheres to the arc panel 51, automatically rolling to remove dust when the rubber roller rotates on the arc panel 51; and a rubber-replacing component 6, which is responsible for replacing the area of ​​the dust-adhesive tape 52 at a set time. The roller removal component 7 includes a pair of guide rods 71. When the pair of rotating rods 42 rotate to the corresponding guide rods 71, they move away from each other, causing the polished rubber roller to fall off. The roller loading component 8 includes a pair of hydraulic rods 81 set on the worktable 1. The pair of hydraulic rods 81 extend for a set time to drive a pair of clamping sleeves 43 to move closer together, completing the clamping of the rubber roller. The cleaning component 9 includes a cleaning brush, which is responsible for cleaning the surface impurities of the rubber roller after coarse grinding. The worktable 1 is set with a coarse grinding area a, a cleaning area b, a fine grinding area c, a dust-adhesive area d, and a replacement area e that the rubber roller needs to pass through in sequence according to a circumferential path, so that the rubber roller can complete all the grinding work and automatically load and unload.

[0038] The bottom of the worktable 1 is fixedly connected to the support frame 17. The worktable 1 has a U-shaped structure and a movable groove is opened on it, so that the rubber roller can rotate and change areas in the movable groove; the coarse grinding area a corresponds to the working area of ​​the coarse grinding mechanism 2, the cleaning area b is the working area of ​​the cleaning component 9, the fine grinding area c is the working area of ​​the fine grinding machine 3, the dust-adhesive area d is the area where the dust-adhesive component 5 is located, and the replacement area e is the working area of ​​the roller disassembly component 7 and the roller assembly component 8.

[0039] Preferably, the cleaning component 9 includes a swing motor and a rotating motor. The swing motor is fixedly connected to the cleaning brush, and the output end of the rotating motor is fixedly connected to a friction wheel wrapped with an elastic bladder. The elastic bladder uses the friction force brought by the elastic positive pressure to rotate the rubber roller at a set angle. During the swinging process, the cleaning brush cleans the impurities on the rubber roller. Since the cleaning component 9 is in the prior art, only this one embodiment is provided here. Any mechanism or solution that can clean debris from the coarsely ground rubber roller can replace the embodiment provided in this solution.

[0040] Please see the appendix Figure 3 The coarse grinding mechanism 2 includes a first electric guide rail 21, a first slider 22 sliding on the first electric guide rail 21, and a coarse grinding machine 23 fixedly connected to the first slider. The fine grinding mechanism 3 includes a second electric guide rail 31, a second slider 32 sliding on the second electric guide rail 31, and a fine grinding machine 33 fixedly connected to the second slider. A touch switch 48 is provided on the worktable 1, and the touch switch 48 is electrically connected to a controller.

[0041] The first electric guide rail 21 and the second electric guide rail 31 are detachably connected to the worktable 1. The coarse grinding machine 23 includes a drive source and a coarse grinding disc connected to the drive source. Similarly, the fine grinding machine 33 includes a drive source and a fine grinding disc.

[0042] Please see the appendix Figure 3 and attached Figure 5 Both the coarse grinding mechanism 2 and the fine grinding mechanism 3 include a geared motor 14 and a second motor base 15 fixedly connected to the bottom of the geared motor 14. The output end of the geared motor 14 is fixedly connected to a linkage shaft 16. The end of the linkage shaft 16 is provided with multiple drive rods 18. The end of the drive rod 18 is provided with an electromagnet and an elastic element. The end of the rubber roller is provided with a drive groove adapted to the drive rod 18.

[0043] A hollow disc is provided at the end of the linkage shaft 16. The inner wall of the hollow disc is fixedly connected to the electromagnet. The drive rod 18 is slidably connected inside the hollow disc. The drive rod 18 is fixedly connected to the inner wall of the hollow disc by an elastic element, which is a return spring. Initially, the drive rod 18 is inserted into the drive groove to ensure that the power of the reduction motor 14 can be smoothly transmitted to the rubber roller, so that the rubber roller rotates slowly to cooperate with the grinding work of the coarse grinding machine 23 and the fine grinding machine 33. Each time the zone is changed, the controller is used to activate the electromagnet, and the drive rod 18 retracts, so that the drive rod 18 is disengaged from the drive groove.

[0044] Initially, the first electric guide rail 21 moves with the coarse grinding disc, and the rubber roller rotates slowly. The speed of the coarse grinding disc is adjustable, and the slow rotation of the rubber roller can achieve full-area grinding. After grinding is completed, the first electric guide rail 21 closes, and the coarse grinding machine 23 stops working. At the same time, the second electric guide rail 31 moves with the fine grinding disc to perform fine grinding on the rubber roller. Depending on the actual situation, the coarse grinding machine 23 moves faster, while the fine grinding machine 33 moves slower. Therefore, the machine waits for the fine grinding machine 33 to finish its work before changing areas. Specifically, when the fine grinding machine 33 moves to the end, it will press the touch switch 48. The touch switch 48 will drive the subsequent rubber changing component 6 to work through the controller.

[0045] Please see the appendix Figure 1 -Appendix Figure 4 The switching component 4 also includes a drive motor 44. The output end of the drive motor 44 is fixedly connected to a drive shaft 45. The drive shaft 45 is fixedly connected to the switching shaft 41. The bottom of the drive motor 44 is provided with a first motor base 46 fixedly connected to the top surface of the workbench 1. A limit strip 47 is fixedly connected to the drive shaft 45. A slot is provided on the rotating rod 42. The rotating rod 42 is slidably connected to the limit strip 47 through the slot.

[0046] The drive motor 44 rotates the switching shaft 41, and rotates 90 degrees each time. In this case, four rubber rollers work simultaneously in different work positions. Each time they rotate, the limit bar 47 rotates the rotating rod 42, completing the switching of different rubber rollers between work areas.

[0047] Please see the appendix Figure 6 -Appendix Figure 8 The dust-adhesive tape 52 includes an adhesive area 521 and a non-adhesive area 522. A shaping plate 53 is fixedly connected to the curved panel 51 to limit the non-adhesive area 522. The shaping plate 53 is responsible for ensuring that the back of the dust-adhesive tape 52 is always in contact with the inner curved surface of the curved panel 51 when it slides on the curved panel 51.

[0048] The adhesive tape 52 can be an edge-free tape, also known as an edge-free tape. Its structure consists of a substrate, an adhesive coating in the middle, and blank sides. The substrate can be one of three types: PET, PP, or cloth. Low-tack or medium-tack PET transparent or matte edge-free tape is selected. It can adhere to micro powder without damaging the adhesive surface. According to the above requirements, one of the following can be purchased from the market: wide edge-free adhesive tape rolls, large rolls of adhesive tape with single-sided adhesive-free adhesive, industrial adhesive tape rolls with a handle edge, 30cm, 40cm, or 50cm adhesive tape rolls, etc. It is preferred to use adhesive tape rolls of a set length.

[0049] The blank areas on both sides are the non-adhesive areas 522. The non-adhesive areas 522 have no adhesive properties and are contained within the plastic sheet, allowing the entire dust-adhesive strip 52 to be molded into an arc shape.

[0050] Please see the appendix Figure 7 -Appendix Figure 8 The adhesive changing component 6 includes a feeding roller 61 and a take-up roller 62. A stepper motor 63 is fixedly connected to the end of the take-up roller 62, and a support frame 64 is rotatably connected to the end of the feeding roller 61. The two ends of the adhesive tape 52 are respectively wrapped around the outer walls of the feeding roller 61 and the take-up roller 62. The stepper motor 63 is electrically connected to the controller.

[0051] When the touch switch 48 is pressed, the adhesive needs to be replaced. The previously used adhesive tape 52, which still has debris adhering to it from the fine grinding, is replaced at the same time. At this time, the stepper motor 63 rotates a set number of times according to the controller. Since the radius also decreases as the layers shrink, the controller needs to strictly control the number of rotations of the take-up roller 62. Then, all the adhesive tape 52 on the arc panel 51 is replaced.

[0052] Subsequently, the rotating rod 42 carries the finely ground rubber roller and rolls it in the adhesive area 521 of the adhesive layer. Because the adhesive area 521 is sticky, the rubber roller will also rotate as it follows the rotating rod 42, which will stick to the surface and achieve the purpose of further cleaning the rubber roller.

[0053] Please see the appendix Figure 9The guide rod 71 includes an inclined surface 711 and a flat surface 712. A U-shaped plate 72 is fixedly connected to the bottom of the guide rod 71. The U-shaped plate 72 is fixedly connected to the workbench 1. When the rotating rod 42 rotates downward and touches the inclined surface 711, it moves outward passively. A first ramp plate 73 for unloading is provided below the workbench 1.

[0054] The inclined section 711 is tilted upwards, with one end close to the inner side of the rotating rod 42 and the other end gradually moving away from the inner side of the rotating rod 42. When the rotating rod 42 rotates to the inclined section 711, it is subjected to outward squeezing force, causing the rotating rod 42 to rotate and slide at the same time. Finally, the clamped rubber roller separates from the corresponding pair of rotating rods 42. Under the action of gravity, the rubber roller falls on the first ramp plate 73 and slides down the ramp.

[0055] The roller loading component 8 includes a second ramp plate 82 for feeding materials. The second ramp plate 82 is provided with a sloping part and a parallel part for storing at least one rubber roller during operation. An arc-shaped baffle 83 is fixedly connected to the end of the second ramp plate 82.

[0056] The top surface of the hydraulic rod 81 is detachably mounted on the bottom surface of the workbench 1. The end of the hydraulic rod 81 abuts against the outer side of the rotating rod 42. When the hydraulic rod 81 is started, it pushes the rotating rod 42 to move and puts the clamping sleeve 43 on both ends of the rubber roller. Then the rotating rod 42 rotates and takes the first rubber roller away. Although it also pushes the subsequent rubber roller, after the rubber roller is taken away, the subsequent rubber roller pushes the front rubber roller to rotate under the action of gravity until the second rubber roller comes to the position of the arc baffle 83 and waits to be fed later.

[0057] Please see the appendix Figure 9 A buffer component is provided at the end of the first ramp 73. The buffer component includes a brake plate 10, a damping rod 11 fixedly connected to the brake plate 10, and a buffer plate 12 fixedly connected to the damping rod 11. A pressure sensor 13 is provided on the brake plate 10.

[0058] Pressure sensor 13 can detect pressure, so that when the rubber roller rolls down, it comes into contact with the pressure sensor 13 through the buffer plate 12, indicating that a rubber roller has detached from the equipment and needs to be fed. At this time, the controller will open the hydraulic rod 81 to bring the new rubber roller into the device, ready to start the work in each zone. At the same time, if the person is not near the machine for a short period of time, multiple rubber rollers will be parked on the first ramp plate 73, and the value of pressure sensor 13 will gradually increase. When it increases to a certain number, an alarm can be set to remind the staff to remove the polished rubber roller.

[0059] The detailed working principle is as follows:

[0060] Pre-cycle stage: First, place the first rubber roller and begin coarse grinding. After coarse grinding is completed, manually turn on the drive motor 44, then turn on the hydraulic rod 81 to install the second rubber roller. Then, while coarse grinding the second rubber roller, clean the first rubber roller. Turn on the drive motor 44 again to install the third rubber roller. Rotate the rotating rod 42 again to begin fine grinding of the first rubber roller. After fine grinding is completed, the fine grinding machine 33 presses the touch switch 48. The touch switch 48 will drive the subsequent rubber changing component 6 to work through the controller. At this point, automatic cycling can begin.

[0061] Post-loop phase:

[0062] Working process of coarse grinding zone a: The first electric guide rail 21 moves the coarse grinding disc, and the rubber roller rotates slowly under the action of the reduction motor 14, drive rod 18 and drive groove. The speed of the coarse grinding disc can be adjusted according to the requirements. The slow rotation of the rubber roller can achieve full-area grinding. After grinding is completed, the first electric guide rail 21 closes and the coarse grinding machine 23 stops working.

[0063] Working process in cleaning area b: The cleaning brush follows the oscillation to clean the rubber roller, achieving the final cleaning work;

[0064] Working process of fine grinding zone c: The second electric guide rail 31 moves with the fine grinding disc to fine grind the rubber roller. The fine grinding machine 33 moves gradually until it reaches the end, and then presses the touch switch 48. The touch switch 48 will drive the subsequent rubber changing component 6 to work through the controller.

[0065] The three working areas are switched by rotating rod 42. However, after rotating rod 42 stops, each area performs its own work simultaneously without interfering with the others. The area stops automatically when the work is completed. The timing of the rotation is when the fine grinding mill 33 and the touch switch 48 are pressed.

[0066] Working process of the dust-adhesive zone d: After receiving the controller signal, the stepper motor 63 automatically starts, the take-up roller 62 rotates accordingly, and the number of rotations is strictly controlled, while the release roller 61 rotates passively, starting to pull the unused part of the dust-adhesive belt 52 onto the arc panel 51, and finally replacing all the dust-adhesive belts 52 on the arc panel 51; the rotating rod 42 carries the rubber roller that has just been finely ground, and rolls it in the rubber area 521 of the adhesive layer belt. Because the rubber area 521 has its own stickiness, the rubber roller will also rotate itself when it rotates with the rotating rod 42, sticking dust to the surface and achieving the purpose of cleaning the rubber roller.

[0067] The working process of changing area e: When the rotating rod 42 rotates to the inclined surface 711, it is subjected to outward squeezing force, causing the rotating rod 42 to rotate and slide at the same time. Finally, the clamped rubber roller separates from the corresponding pair of rotating rods 42. Under the action of gravity, the rubber roller falls on the first ramp plate 73 and slides down the ramp. When the rubber roller rolls down, it contacts the pressure sensor 13 through the buffer plate 12, indicating that one rubber roller has been detached from the equipment and needs to be fed. At this time, the controller will activate the hydraulic rod 81. After the hydraulic rod 81 is activated, it pushes the rotating rod 42 to move and put the clamping sleeve 43 on both ends of the rubber roller. Then the rotating rod 42 rotates and takes away the first rubber roller. After the rubber roller is taken away, the subsequent rubber roller pushes the previous rubber roller to rotate under the action of gravity until the second rubber roller comes to the position of the arc baffle 83, waiting to be fed.

[0068] A method for operating a surface grinding and repair device for a spinning machine rubber roller, applied to the aforementioned surface grinding and repair device for a spinning machine rubber roller, comprises the following steps:

[0069] First, place the rubber rollers on the second ramp plate 82 and stack multiple rollers continuously. Then, turn on the hydraulic rod 81 to complete the installation of the rubber rollers and rotate them to the position of the rough grinding machine 23. After the rough grinding work is completed, rotate the rotating rod 42 and grind the second and third rubber rollers in the same way, and start the self-circulation working mode smoothly.

[0070] The first electric guide rail 21, the second electric guide rail 31, the geared motor 14, the coarse grinding machine 23 and the fine grinding machine 33 are turned on in sequence to start coarse grinding of the new rubber roller and fine grinding of the rubber roller after coarse grinding.

[0071] After the fine grinding mill 33 contacts the touch switch 48, the stepper motor 63 starts to rotate the take-up roller 62 to replace the use area of ​​the dust-adhesive belt 52;

[0072] After the rubber roller finishes adhering to the dust, it touches the guide rod 71, causing the pair of rotating rods 42 to separate, and the rubber roller that has finished adhering to the dust will fall automatically.

[0073] When the rubber roller rolls to the end on the first ramp 73, it squeezes the pressure sensor 13, causing the hydraulic rod 81 to start and, through the rotating rod 42, to put the rotating sleeve into the end of the new rubber roller.

[0074] The drive motor 44 drives the four rubber rollers to rotate, which on the one hand realizes the switching of each rubber roller zone, and on the other hand drives the new rubber roller to rotate to the coarse grinding zone a.
