Description

Technical Field

[0001] This application relates to the field of steel strip processing technology, and in particular to an ultra-thin sheet roll sanding equipment. Background Technology

[0002] In the modern ultra-thin steel strip processing industry, to meet the needs of different application scenarios, steel strips need to undergo various surface treatments before being made into products. Processes such as sandblasting, grinding, polishing, embossing, and chemical treatment are widely used. Among them, grinding treatment can give steel strips a unique texture and surface properties, and is therefore highly favored.

[0003] A typical ultra-thin sheet metal roll sanding machine's core structure includes the main body of the machine, along with a sanding belt, tension roller, polishing shaft, and bottom roller mounted on the main body. The sanding belt is wound around the tension roller and polishing shaft to form a sanding structure. The width of the sanding belt is smaller than the width of the steel strip, and the two sides of the sanding belt are equidistant from the two sides of the steel strip, thus achieving uniform sanding of the steel strip surface. During the sanding operation, the bottom roller acts as a guide, directing the steel strip along a predetermined path, allowing the steel strip to pass through the sanding belt and fully contact it to complete the sanding process. Finally, the sanded steel strip is output from the discharge port of the main body of the machine.

[0004] To facilitate the transportation and subsequent storage of steel strip, a take-up roller is often installed at the discharge port of the main equipment to take up the sanded steel strip and coil it into a roll. However, the take-up roller requires manual intervention during the coiling process. The steel strip needs to be guided to slowly wrap around the take-up roller once or even multiple times to achieve the initial connection between the take-up roller and the steel strip. The take-up process is cumbersome and affects processing efficiency. Summary of the Invention

[0005] To simplify the winding operation of the take-up roller, improve the processing efficiency of steel strip, and reduce manual intervention, this application provides an ultra-thin sheet roll sanding device.

[0006] The ultra-thin sheet roll sanding equipment provided in this application adopts the following technical solution: A sanding device for ultra-thin sheet rolls includes a main body and a mounting frame at the discharge port of the main body. A take-up roller is rotatably mounted on the mounting frame. A constraint groove is formed on the peripheral wall of the take-up roller, into which the end of a steel strip can extend. A fixed tooth is fixedly provided on one side wall of the constraint groove, and a movable groove is formed on the other side wall of the constraint groove. A movable tooth is slidably disposed in the movable groove. A movable mechanism is also provided inside the take-up roller to drive the movable tooth to slide. The movable tooth can abut against the fixed tooth and together clamp the steel strip extending into the constraint groove.

[0007] By adopting the above technical solution, when winding the sanded steel strip, the end of the steel strip is guided and inserted into the constraint groove on the circumferential wall of the winding roller. Then, the movable mechanism is activated, which drives the movable teeth in the movable groove to slide, so that the movable teeth abut against the fixed teeth and together firmly clamp the end of the steel strip that extends into the constraint groove. At this time, the winding roller can directly start to rotate and wind the steel strip, without the need for manual guidance to slowly wind the steel strip around the winding roller multiple times to achieve the initial connection. This simplifies the winding operation process of the winding roller, improves the processing efficiency of the steel strip, and reduces manual intervention.

[0008] Preferably, the mounting frame includes a fixed frame and a movable frame. The fixed frame is fixedly connected to the main body of the equipment, and the movable frame is slidably connected to the main body of the equipment along a direction close to or away from the fixed frame. An electric cylinder is provided on the main body of the equipment to drive the movable frame to slide. A docking plate is rotatably provided on the side of the movable frame close to the fixed frame. The take-up roller is located between the movable frame and the fixed frame. The axis of the docking plate coincides with that of the take-up roller. One end of the take-up roller is rotatably connected to the fixed frame, and the other end of the take-up roller is docked with the docking plate. The take-up roller and the docking plate can be separated from each other.

[0009] By adopting the above technical solution, after the take-up roller completes the take-up of a steel strip, the electric cylinder can be activated. The electric cylinder drives the movable frame to slide away from the fixed frame. At this time, the take-up roller and the docking plate separate from each other, and the take-up roller loses its constraint on the side close to the movable frame, so that the ultra-thin sheet roll can be removed from one side of the take-up roller, thus completing the disassembly of the ultra-thin sheet roll.

[0010] Preferably, the take-up roller includes a rotating disk, a connecting rod, a base column, outer arc plates, and a carriage. The rotating disk is rotatably connected to a fixed frame. The base column is located on the side of the rotating disk away from the fixed frame, and the axis of the base column coincides with the rotation axis of the rotating disk. The base column and the rotating disk are fixedly connected by the connecting rod. The base column has several grooves spaced apart and symmetrically arranged in the circumferential direction. The grooves are opened along the radial direction of the base column. One end of the carriage slides in the groove, and the other end of the carriage passes through the peripheral wall of the base column. Several outer arc plates are provided, each corresponding to a carriage. The outer arc plates are fixedly connected to the other end of the carriages. All the outer arc plates are symmetrical about the axis of the base column. The outer walls of all the outer arc plates together form the peripheral wall of the take-up roller. A gap is left between adjacent outer arc plates for the outer arc plates to move. The take-up roller is also provided with a sliding component for driving the carriage to slide.

[0011] By adopting the above technical solution, when it is necessary to disassemble the ultra-thin sheet roll after winding, the sliding assembly is activated to drive the carriage to slide along the slide groove towards the axis of the base column, causing the outer arc plates to retract inward synchronously. Because there is a movable gap between adjacent outer arc plates, the outer arc plates can move towards the axis, reducing the diameter of the winding roller's peripheral wall, which consists of all the outer arc plates, and creating a gap with the inner wall of the ultra-thin sheet roll. At this point, the ultra-thin sheet roll can be separated from the winding roller more easily, without the need for forced disassembly by overcoming the friction between the sheet roll and the roller body, as is required with traditional winding rollers. This further simplifies the unloading process and improves work efficiency.

[0012] Preferably, the sliding assembly includes a movable ring, a connecting rod, and a pushing member. A set of movable rings are symmetrically arranged on both sides of the base column, and the axis of the movable ring coincides with that of the base column. Several connecting rods are spaced apart and symmetrically arranged in the circumferential direction of the movable rings. Each connecting rod on the movable ring corresponds to a slide. The connecting rod is inclined between the movable ring and the slide. One end of the connecting rod is hinged to the side wall of the slide, and the other end of the connecting rod is hinged to the movable ring. The pushing member is used to drive the movable ring to move in a direction closer to or away from the base column.

[0013] By adopting the above technical solution, when it is necessary to adjust the outer diameter of the take-up roller, the pusher drives the movable ring to move along the axis of the base column. Since the connecting rod is inclined and its two ends are respectively hinged to the movable ring and the carriage, the axial movement of the movable ring is converted into the radial sliding of the carriage through the connecting rod. When the movable ring moves closer to the base column, the connecting rod pushes the carriage to expand outward, increasing the outer diameter of the take-up roller composed of the outer arc plate; conversely, when the movable ring moves away from the base column, the carriage contracts inward, decreasing the outer diameter of the take-up roller. This facilitates the simultaneous synchronous movement of all carriages.

[0014] Preferably, a guide rod parallel to the axis is fixedly installed on the side wall of the base column, and a guide groove penetrating both ends of the movable ring is provided, with the guide rod slidingly engaging with the guide groove.

[0015] By adopting the above technical solution, the sliding cooperation between the guide rod and the guide groove provides guidance for the movement of the movable ring along the axis of the base column. When the pusher drives the movable ring to move, the guide rod and the guide groove restrict the radial displacement and rotation of the movable ring, ensuring that the movable ring always moves in a straight line along the axis of the base column, thus ensuring the synchronicity and stability of the expansion or contraction process of the outer arc plate.

[0016] Preferably, the pusher includes a mandrel, the axis of which coincides with the axis of the base column. The mandrel passes through the base column and the rotating disk, and extends out from the side of the fixed frame away from the movable frame. The mandrel is rotatably connected to the base column and the rotating disk. The movable ring is sleeved on the mandrel. The mandrel has a set of threaded segments with equal pitch and opposite directions. One of the threaded segments engages with one of the movable rings, and the other threaded segment engages with another movable ring.

[0017] By adopting the above technical solution, when it is necessary to adjust the outer diameter of the take-up roller, the spindle is rotated. The rotation of the spindle will cause the two movable rings on both sides to move synchronously in opposite directions along the axis of the base column, thereby controlling the synchronous reverse movement of the two movable rings at the same time.

[0018] Preferably, one of the outer arc plates is a first arc plate, and the remaining outer arc plates are second arc plates. The constraint groove, movable groove, and movable teeth are all provided on the first arc plate. A drive groove communicating with the movable groove is opened on the inner side of the first arc plate. The movable mechanism includes a first gear, a first rack, and a power component. The first gear is rotatably disposed in the drive groove. The first rack is integrally formed on the movable teeth. The first gear and the first rack mesh with each other. The power component is used to drive the first gear to rotate.

[0019] By adopting the above technical solution, when it is necessary to fix the end of the steel strip, the power component drives the first gear to rotate. Through the meshing transmission between the first gear and the first rack, the rotational motion of the first gear is converted into the sliding motion of the movable teeth, so that the movable teeth move towards the fixed teeth, thereby achieving reliable clamping of the end of the steel strip.

[0020] Preferably, the power assembly includes a driving pulley, a driven pulley, a transmission belt, a second gear, and a second rack. The second rack is fixed to the side wall of the base column and is parallel to the opening direction of the slide groove. The second gear is rotatably connected to the side wall of the carriage and meshes with the second rack. The driving pulley is coaxially fixed with the second gear, and the driven pulley is coaxially fixed with the first gear. The transmission belt is configured to drive between the driving pulley and the driven pulley. One end of the transmission belt is sleeved on the driving pulley, and the other end of the transmission belt is sleeved on the driven pulley.

[0021] By adopting the above technical solution, when the sliding assembly drives the carriage to slide radially along the slide groove, the second gear, which is rotatably connected to the carriage, will be forced to rotate due to its meshing with the second rack fixed to the base column. Since the driving pulley is coaxially fixed with the second gear, the rotation of the second gear will synchronously drive the first gear to rotate through the transmission chain of the driving pulley, transmission belt, and driven pulley. The first gear meshes with the first rack of the movable teeth, ultimately realizing the automatic sliding of the movable teeth. In this way, when the carriage slides outward, the diameter of the winding roller's peripheral wall increases, and at the same time, through the transmission of the second gear, driving pulley, transmission belt, driven pulley, first gear, and first rack, the movable teeth approach the fixed teeth, automatically clamping the end of the steel strip. Conversely, when it is necessary to disassemble the ultra-thin sheet roll, the carriage slides inward, the diameter of the winding roller's peripheral wall decreases, and at the same time, the movable teeth loosen from the fixed teeth to facilitate the disassembly of the ultra-thin sheet roll.

[0022] Preferably, the docking plate has a docking hole on the end face near the fixed frame, and the connecting rod is inserted into the docking hole and abuts against the docking hole.

[0023] By adopting the above technical solution, when the movable frame approaches the fixed frame under the drive of the electric cylinder, the connecting rod is inserted into the docking hole and abuts against the inner wall of the docking hole, so that the other end of the winding roller is rigidly connected to the docking plate through the connecting rod, ensuring that the axis of the winding roller remains coaxial with the docking plate during rotation, minimizing shaking or deviation, thereby ensuring the balance and stability of the steel strip winding.

[0024] Preferably, a drive sprocket and a driven sprocket are rotatably mounted on the fixed frame. The driven sprocket is coaxially fixed to the rotating disk. A transmission chain is provided between the drive sprocket and the driven sprocket. One end of the transmission chain meshes with the drive sprocket, and the other end of the transmission chain meshes with the driven sprocket. A motor is mounted on the fixed frame, and the drive shaft of the motor is coaxially fixed to the drive sprocket.

[0025] By adopting the above technical solution, the motor drives the active sprocket to rotate, and the active sprocket drives the driven sprocket to rotate synchronously through the transmission chain. Since the driven sprocket is fixed coaxially with the rotating disk, it drives the winding roller to rotate as a whole to achieve the winding of the steel strip.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting constraint grooves, fixed teeth, movable grooves, movable teeth, and movable mechanisms, the initial connection can be achieved without manual guidance of the steel strip to slowly wrap around the take-up roller multiple times, simplifying the take-up roller's winding operation process, improving the processing efficiency of the steel strip, and reducing manual intervention; 2. By setting up a rotating disk, connecting rod, base column, outer arc plate, slide, slide groove, sliding assembly, movable ring, connecting rod, pusher, and mandrel, the outer wall of the take-up roller is easily retracted, so as to facilitate the unloading of the completed ultra-thin sheet roll from the take-up roller and reduce the friction between the inner wall of the ultra-thin sheet roll and the outer wall of the take-up roller during the unloading process; 3. By setting up a first gear, a first rack, a driving pulley, a driven pulley, a transmission belt, a second gear, and a second rack, the radial movement of the carriage is converted into the clamping action of the movable teeth. No additional power source is required, so that when it is necessary to disassemble the ultra-thin sheet roll, the carriage slides inward, the outer wall of the winding roller retracts inward, and at the same time the movable teeth move away from the fixed teeth to release the end of the steel strip, so as to disassemble the ultra-thin sheet roll.

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0035] This application discloses an ultra-thin sheet roll sanding device. (Refer to...) Figure 1 and Figure 2 The equipment includes a main body 1, a mounting frame 12, and a winding roller 2. The mounting frame 12 is located at the discharge port 11 of the main body 1, from which the steel strip that has undergone sandblasting is output. The winding roller 2 is rotatably mounted on the mounting frame 12 and can wind up the steel strip exiting from the discharge port 11 of the main body 1, facilitating the subsequent transportation and storage of the ultra-thin steel strip.

[0036] Reference Figure 3 and Figure 4A constraint groove 2111 is provided on the peripheral wall of the take-up roller 2. The constraint groove 2111 is opened along the axial direction of the take-up roller 2 and passes through both ends of the take-up roller 2. The end of the steel strip can be inserted into the constraint groove 2111. A fixed tooth 2112 is fixedly provided on one side wall of the constraint groove 2111, and a movable groove 2113 is provided on the other side wall of the constraint groove 2111. A movable tooth 2114 is slidably provided in the movable groove 2113. The movable tooth 2114 can move closer to or further away from the fixed tooth 2112.

[0037] Reference Figure 4 and Figure 7 The take-up roller 2 is also equipped with a movable mechanism 3 for driving the movable teeth 2114 to slide. The movable teeth 2114 can abut against the fixed teeth 2112 and together clamp the steel strip that extends into the constraint groove 2111. When the end of the guide steel strip extends into the constraint groove 2111, the movable mechanism 3 drives the movable teeth 2114 in the movable groove 2113 to slide, so that the movable teeth 2114 abut against the fixed teeth 2112 and together firmly clamp the end of the steel strip that extends into the constraint groove 2111. At this time, the take-up roller 2 can directly start rotating to take up the steel strip.

[0038] To facilitate the disassembly of the rolled-up ultra-thin sheet coil, refer to... Figure 2 The mounting frame 12 includes a fixed frame 121 and a movable frame 122. The fixed frame 121 is fixedly connected to the equipment body 1, and the movable frame 122 is slidably connected to the equipment body 1 in a direction close to or away from the fixed frame 121. An electric cylinder 14 is fixedly installed on the equipment body 1, and the output end of the electric cylinder 14 is fixedly connected to the movable frame 122. The electric cylinder 14 is used to drive the movable frame 122 to slide. A docking plate 123 is rotatably installed on the side of the movable frame 122 close to the fixed frame 121. The take-up roller 2 is located between the movable frame 122 and the fixed frame 121. The axis of the docking plate 123 coincides with that of the take-up roller 2. One end of the take-up roller 2 is rotatably connected to the fixed frame 121, and the other end of the take-up roller 2 is docked with the docking plate 123. The take-up roller 2 and the docking plate 123 can be separated from each other. After the take-up roller 2 completes the take-up of an ultra-thin sheet roll, the electric cylinder 14 drives the movable frame 122 to slide away from the fixed frame 121. At this time, the take-up roller 2 separates from the docking plate 123, and the take-up roller 2 loses its constraint on the side close to the movable frame 122, so that the ultra-thin sheet roll can be removed from one side of the take-up roller 2, thus completing the disassembly of the ultra-thin sheet roll.

[0039] To reduce the frictional resistance between the take-up roller 2 and the ultra-thin sheet roll during disassembly, refer to... Figure 2 , Figure 3 and Figure 5The take-up roller 2 includes a rotating disk 22, a connecting rod 23, a base column 24, an outer arc plate 21, and a carriage 25. The rotating disk 22 is rotatably connected to the fixed frame 121 on the side closer to the movable frame 122. The base column 24 is located on the side of the rotating disk 22 away from the fixed frame 121, and the axis of the base column 24 coincides with the rotation axis of the rotating disk 22. The base column 24 and the rotating disk 22 are fixedly connected by the connecting rod 23. In this embodiment, four common connecting rods 23 are symmetrically and fixedly arranged along the circumference of the base column 24. One end of the common connecting rod 23 is fixed to the rotating disk 22, and the middle part of the common connecting rod 23 passes through the base column 24 and is fixedly connected to the base column 24. The docking disk 123 has docking holes 1231 on the end face near the fixed frame 121. The docking holes 1231 correspond one-to-one with the common connecting rods 23. The other end of the common connecting rod 23 is inserted into the docking hole 1231 and abuts against the side wall and end wall of the docking hole 1231, thereby realizing the separation and docking of the winding roller 2 and the docking disk 123.

[0040] Reference Figure 3 and Figure 5 The base column 24 is provided with a plurality of sliding grooves 241 spaced apart and symmetrically in the circumferential direction. In this embodiment, four sliding grooves 241 are provided. The sliding grooves 241 are opened along the radial direction of the base column 24 and penetrate the end wall of the base column 24. One end of the slide 25 slides in the sliding groove 241, and the other end of the slide 25 penetrates the circumferential wall of the base column 24. A plurality of outer arc plates 21 are provided and correspond one-to-one with the slide 25. The outer arc plates 21 are fixedly connected to the other end of the slide 25. All the outer arc plates 21 are symmetrical about the axis of the base column 24. The outer walls of all the outer arc plates 21 together form the circumferential wall of the take-up roller 2. A gap is left between adjacent outer arc plates 21 for the outer arc plates 21 to move. Specifically, one of the outer arc plates 21 is the first arc plate 211, and the remaining outer arc plates 21 are the second arc plates 212. The constraint groove 2111, the movable groove 2113, and the movable tooth 2114 are all provided on the first arc plate 211.

[0041] Reference Figure 3The take-up roller 2 is also equipped with a sliding assembly 4 for driving the carriage 25 to slide. The sliding assembly 4 includes a movable ring 41, a connecting rod 42, and a pushing member. A set of movable rings 41 are symmetrically arranged on both sides of the base column 24, and the axis of the movable rings 41 coincides with that of the base column 24. Several connecting rods 42 are spaced apart and symmetrically arranged in the circumferential direction of the movable rings 41, and each connecting rod 42 on the movable ring 41 corresponds one-to-one with the carriage 25. The connecting rods 42 are inclined between the movable rings 41 and the carriage 25. One end of the connecting rod 42 is hinged to the side wall of the carriage 25, and the other end of the connecting rod 42 is hinged to the movable ring 41. The movable ring 41 can move in a direction close to or away from the base column 24. Specifically, a guide rod 242 parallel to the axis is fixedly arranged on the side wall of the base column 24, and a guide groove 411 penetrating both ends of the movable ring 41 is opened, and the guide rod 242 slides in engagement with the guide groove 411. In this embodiment, four guide rods 242 are symmetrically arranged in the circumferential direction of the base column 24, and four guide grooves 411 are opened on the movable ring 41. The guide rods 242 and the guide grooves 411 correspond one-to-one. The guide rods 242 are inserted into the corresponding guide grooves 411 to guide the movement of the movable ring 41.

[0042] Reference Figure 3 and Figure 5 The pusher is used to drive the movable ring 41 to move in a direction closer to or away from the base column 24. The pusher includes a spindle 43, the axis of which coincides with the axis of the base column 24. The spindle 43 passes through the base column 24 and the rotating disk 22, and extends out from the side of the fixed frame 121 away from the movable frame 122. The end face of the spindle 43 extending out of the fixed frame 121 has a hole for inserting a hex screwdriver to facilitate independent rotation of the spindle 43. The spindle 43 is rotatably connected to the base column 24 and the rotating disk 22. The movable ring 41 is sleeved on the spindle 43. The spindle 43 has a set of threaded segments 421 with equal pitch and opposite directions. One threaded segment 421 is threadedly engaged with one movable ring 41, and the other threaded segment 421 is threadedly engaged with another movable ring 41.

[0043] Reference Figure 3 When the ultrathin sheet roll needs to be disassembled, the mandrel 43 is driven to rotate relative to the take-up roller 2. The rotation of the mandrel 43 forces the movable rings 41 on both sides of the base column 24 away from the base column 24. The movable rings 41 pull one end of all the connecting rods 42 connected to them, making all the connecting rods 42 more horizontal. All the carriages 25 retract inward, and all the outer arc plates 21 (the first arc plate 211 and all the second arc plates 212) move closer to the center of the base column 24. The outer wall of the take-up roller 2 contracts less, and the gap between the outer wall of the take-up roller 2 and the inner wall of the ultrathin sheet roll increases. This reduces the frictional resistance between the take-up roller 2 and the ultrathin sheet roll during disassembly.

[0044] To facilitate moving the movable tooth 2114 closer to or further away from the fixed tooth 2112, refer to Figure 7The inner side of the first arc plate 211 has a drive groove 2115 that connects to the movable groove 2113. The movable mechanism 3 includes a first gear 32, a first rack 31, and a power component 33. The first gear 32 is rotatably disposed in the drive groove 2115, and the first rack 31 is integrally formed on the movable teeth 2114. The first gear 32 and the first rack 31 mesh with each other. The power component 33 is used to drive the first gear 32 to rotate.

[0045] Reference Figure 5 and Figure 7 Specifically, the power assembly 33 includes a driving pulley 331, a driven pulley 332, a transmission belt 333, a second gear 334, and a second rack 335. The second rack 335 is fixed on the side wall of the base column 24 and is parallel to the opening direction of the groove 241 where the slide 25 connected to the first arc plate 211 is located. The second gear 334 is rotatably connected to the side wall of the slide 25 corresponding to the first arc plate 211. The second gear 334 and the second rack 335 mesh with each other. The driving pulley 331 and the second gear 334 are coaxially fixed. The driven pulley 332 and the first gear 32 are coaxially fixed through the same rotating shaft. The transmission belt 333 is configured to drive between the driving pulley 331 and the driven pulley 332. One end of the transmission belt 333 is sleeved on the driving pulley 331, and the other end of the transmission belt 333 is sleeved on the driven pulley 332.

[0046] When the slide 25 moves radially outward along the slide groove 241, the second gear 334, which is rotatably connected to the slide 25, will be forced to rotate clockwise due to meshing with the second rack 335 fixed to the base column 24. The rotation of the second gear 334 will synchronously drive the first gear 32 to rotate clockwise through the transmission chain 1213 of the driving pulley 331, the transmission belt 333 and the driven pulley 332. The first gear 32 meshes with the first rack 31 of the movable tooth 2114, and finally realizes the automatic sliding of the movable tooth 2114, so that the movable tooth 2114 approaches the fixed tooth 2112. Conversely, when the carriage 25 moves radially inward along the slide groove 241, the circumferential wall of the take-up roller 2 contracts. At the same time, through the transmission of the second gear 334, the driving pulley 331, the transmission belt 333, the driven pulley 332, the first gear 32, and the first rack 31, the movable tooth 2114 moves away from the fixed tooth 2112, automatically releasing the end of the steel strip. In this way, while releasing the inner wall of the ultra-thin sheet roll, the end of the steel strip is released at the same time, further realizing the rapid disassembly of the ultra-thin sheet roll.

[0047] To facilitate the rotation of the take-up roller 2 and the winding of the steel strip, refer to... Figure 2A drive sprocket 1211 and a driven sprocket 1212 are rotatably mounted on the fixed frame 121. The driven sprocket 1212 is coaxially fixed to the rotating disk 22. A transmission chain 1213 is provided between the drive sprocket 1211 and the driven sprocket 1212, with one end of the transmission chain 1213 meshing with the drive sprocket 1211 and the other end meshing with the driven sprocket 1212. A motor 1214 is mounted on the fixed frame 121, and the drive shaft of the motor 1214 is coaxially fixed to the drive sprocket 1211. The motor 1214 drives the drive sprocket 1211 to rotate, and through the transmission chain 1213 drives the driven sprocket 1212 to rotate, thereby driving the rotating disk 22 to rotate, thus driving the take-up roller 2 to rotate and wind up the steel strip. The motor 1214 is a servo motor.

[0048] The implementation principle of the ultra-thin sheet roll sanding equipment in this application embodiment is as follows: During the process of coiling the steel strip, the constraint groove 2111 is oriented towards the discharge port 11. Then, a hex screwdriver is inserted into the insertion hole and rotated. At this time, the motor 1214 hinders the rotation of the drive sprocket 1211, and then hinders the rotation of the take-up roller 2 through the transmission chain 1213 and the driven sprocket 1212, so that the mandrel 43 and the take-up roller 2 rotate relative to each other. On the one hand, the mandrel 43 drives the movable ring 41 to approach the base column 24 through the threaded section 421. The movable ring 41 pushes one end of all the connecting rods 42 connected to it, and all the connecting rods 42 become more vertical. All the slides 25 extend outward, and all the outer arc plates 21 (including the first arc plate 211 and the second guard plate 212) extend outward until a smooth peripheral wall of the take-up roller 2 is formed. On the other hand, during the process of the first arc plate 211 extending outward, the constraint groove 2111 is fitted onto the steel strip extending into the discharge port 11, and the second gear Because of the engagement with the second rack 335 fixed to the base column 24, the second gear 334 is forced to rotate clockwise. The rotation of the second gear 334 will synchronously drive the first gear 32 to rotate clockwise through the transmission chain 1213 of the driving pulley 331, the transmission belt 333 and the driven pulley 332. The first gear 32 engages with the first rack 31 of the movable tooth 2114, and finally realizes the automatic sliding of the movable tooth 2114, so that the movable tooth 2114 approaches the fixed tooth 2112 and clamps and fixes the end of the steel strip. The motor 1214 drives the take-up roller 2 to rotate through the driving sprocket 1211, the transmission chain 1213 and the driven sprocket 1212, and the steel strip is wound into a coil on the take-up roller 2.

[0049] During the separation of the ultra-thin sheet roll from the take-up roller 2, the electric cylinder 14 is first activated. The output end of the electric cylinder 14 pushes the movable frame 122 to slide away from the fixed frame 121. As the movable frame 122 moves, the docking plate 123, which is rotatably connected to it, gradually separates from the take-up roller 2, causing the end of the take-up roller 2 near the movable frame 122 to lose its constraint, creating space for subsequent disassembly operations. Then, a hex screwdriver is inserted into the socket, and by rotating the screwdriver in the opposite direction, the mandrel 43 is driven to rotate relative to the take-up roller 2. The rotation of the mandrel 43 forces the movable ring 41 away from the base column 24. Firstly, this pulls one end of all the connecting rods 42 connected to it, making all the connecting rods 42 more horizontal. Driven by the connecting rod 42, all the carriages 25 retract inward, thereby causing the outer arc plates 21 (including the first arc plate 211 and all the second arc plates 212) fixedly connected to the carriages 25 to move closer to the center of the base column 24. Consequently, the outer wall of the take-up roller 2 contracts and decreases, increasing the gap between the outer wall of the take-up roller 2 and the inner wall of the ultra-thin sheet roll, thus reducing the frictional resistance between them. Secondly, as the carriages 25 move radially inward along the slide groove 241, the second gear 334, rotatably connected to the carriages 25, will rotate counterclockwise due to its meshing with the second rack 335 fixed to the base column 24. The rotation of the second gear 334, through the driving pulley 331, the transmission belt 333, and the driven pulley 332, synchronously drives the first gear 32 to rotate counterclockwise. The first gear 32 meshes with the first rack 31 of the movable tooth 2114, ultimately causing the movable tooth 2114 to move away from the fixed tooth 2112 and automatically release its grip on the end of the steel strip. In this way, the end of the steel strip is released at the same time as the inner wall of the ultra-thin sheet roll, further realizing the rapid disassembly of the ultra-thin sheet roll.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
