Description

Technical Field

[0001] This utility model relates to the technical field of cutting wire processing equipment, and in particular to a rewinding machine with a sharpened blade. Background Technology

[0002] Diamond wire is a high-performance cutting tool with a metal wire base and diamond microparticles fixed to its surface through electroplating or chemical deposition. Due to its high cutting efficiency, high precision, and low wear, it is widely used in precision machining, semiconductors, photovoltaics, and other fields.

[0003] During the processing of diamond wire, the diamond wire obtained after electroplating or chemical deposition is generally wound onto a spool. However, if the following situations occur, the diamond wire needs to be rewound (i.e., re-wound) before it can be shipped to the customer: ① Defects such as wire piling occur during the winding of the diamond wire, resulting in the product appearance not meeting the customer's requirements; ② The serrations of the diamond wire are not sharp and cannot achieve the best cutting state, so it needs to be sharpened.

[0004] However, due to the less-than-ideal structural configuration of current rewinding equipment, problems such as generally poor winding quality and low grinding and sharpening efficiency are common when rewinding diamond wire. As a result, the production needs of diamond wire cannot be met satisfactorily.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a rewinding machine with a sharpening function. Its structure is reasonable, novel and simple, with high winding quality, good grinding consistency and high grinding efficiency, which well meets the production needs of rope and has very good practicality.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a blade-opening and rewinding machine, comprising:

[0008] The base is provided with two working chambers spaced apart and arranged side by side along a first horizontal direction and two mounting plates spanning above the two working chambers respectively; each of the working chambers is provided with a lifting mechanism;

[0009] The winding device is configured in two sets, each corresponding to one of the two working chambers. One set of the winding device is used to release the yarn, and the other set is used to rewind the yarn. Each set of the winding device is equipped with a spool drive mechanism, a lead-wire mechanism, and a yarn position adjustment mechanism. The spool drive mechanism includes a main pin and a secondary pin spaced apart and opposite to each other in the working chamber along the first horizontal direction, a drive unit A capable of driving the main pin to rotate, and a drive unit B capable of driving the secondary pin to move closer to or away from the main pin. That is, when the lifting mechanism lifts the winding wheel placed on it to a set height position, the drive unit B and the drive unit A can work together to make the main pin and the secondary pin clamp the winding wheel and drive the winding wheel to rotate. The lead-wire mechanism and the yarn position adjustment mechanism are respectively mounted on the corresponding mounting plate frame. The lead-wire mechanism has multiple winding wires. The system includes first guide wheels arranged at preset path intervals, with at least one first guide wheel capable of position adjustment to regulate the tension of the cable. The cable posture adjustment mechanism comprises an adjustment component and a linear drive module. The adjustment component includes a bracket with a threading hole at the bottom, an angle sensor mounted on the bottom of the bracket, and second guide wheels and two third guide wheels movably mounted on the bracket. The second guide wheel is positioned close to the threading hole, and the two third guide wheels are arranged side-by-side above the second guide wheel, with a gap between them for the cable to pass through. The angle sensor senses the swing angle of the second or third guide wheel. The linear drive module is connected to the bracket and drives the entire adjustment component to reciprocate along a first horizontal direction, thereby adjusting the cable segment located between the threading hole and the winding wheel to a preset posture.

[0010] A sharpening device is installed between the two sets of winding devices to sharpen the wire on both sides.

[0011] As a further improvement of this utility model, the two opposing sides of the main ejector pin and the secondary ejector pin are both annular disk surfaces, and the annular disk surface is provided with a planar central region and an inclined surface region extending radially outward from the periphery of the central region.

[0012] As a further improvement of this utility model, in each group of winding devices, the main ejector pin is rotatably mounted on the machine base via a rotating shaft, and the auxiliary ejector pin is mounted on the machine base via a sliding rotating component;

[0013] The drive unit A is provided with a servo motor positioned on the base, two synchronous pulleys respectively fixedly sleeved on the output shaft of the servo motor and the rotating shaft, and a synchronous belt wound around the two synchronous pulleys; the drive unit B is provided with a drive cylinder positioned on the base, the piston rod of the drive cylinder is connected to the sliding rotating component, and can drive the sliding rotating component and the auxiliary ejector pin to reciprocate along the first horizontal direction.

[0014] As a further improvement of this utility model, in each group of winding devices, the rope position adjustment mechanism is located below the lead wire mechanism and close to the winding wheel built into the working chamber.

[0015] As a further improvement of this utility model, in each group of winding devices, the lead wire mechanism is further provided with a position adjustment drive unit. The position adjustment drive unit is provided with a drive motor fixedly mounted on the mounting plate frame and a transmission rod positioned and connected to the output shaft of the drive motor. A first guide wheel is rotatably mounted on the transmission rod. In addition, the remaining first guide wheels that are not installed and cooperated with the transmission rod are rotatably mounted on the mounting plate frame respectively.

[0016] As a further improvement of this utility model, the sharpening device includes a mounting frame, multiple lower guide grinding components, multiple upper guide grinding components, a lifting drive mechanism, and an air blowing mechanism. The mounting frame is positioned between two mounting plates. Multiple lower guide grinding components are spaced apart at the lower part of the mounting frame along the first horizontal direction. Each lower guide grinding component has a lower guide rod for winding a wire and a lower sharpening block for sharpening the wire, and the upper surfaces of the multiple lower sharpening blocks are flush. Multiple upper guide grinding components are spaced apart from the multiple lower guide grinding components along the first horizontal direction. Above, each of the multiple upper guide grinding components is provided with an upper guide rod for winding the rope and an upper sharpening block for grinding and sharpening the rope. The lower end faces of the multiple upper sharpening blocks are flush. Furthermore, the multiple upper guide grinding components can also move downward relative to the multiple lower guide grinding components under the drive of the lifting drive mechanism, so that the lower end faces of the multiple upper sharpening blocks and the upper end faces of the multiple lower sharpening blocks respectively contact the surface of the rope, thereby achieving double-sided grinding and sharpening of the rope. The air blowing mechanism can blow and sweep the rope passing between the lower end face of the upper sharpening block and the upper end face of the lower sharpening block.

[0017] The beneficial effects of this utility model are: ① The overall structural design of the rewinding machine described in this utility model is reasonable, novel, and concise. The various devices / mechanisms are organically coordinated and highly integrated, achieving the following: adaptive correction and automatic tension adjustment functions during winding, significantly improving winding quality; and double-sided sharpening during grinding, significantly improving grinding consistency and efficiency. This effectively meets the production needs of wires (such as diamond wire) and has excellent practicality. ② In the rewinding machine, both sets of winding devices can rotate in both directions, meaning each set can be used for both unwinding and rewinding, significantly improving the processing flexibility of the rewinding machine.

[0026] The preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] This embodiment provides a rewinding and sharpening machine for automating the rewinding and double-sided sharpening of wires (including but not limited to diamond wire).

[0029] Please see the appendix Figure 1 To be continued Figure 6 As shown, the implementation structure of the rewinding machine with sharpening blade provided in this embodiment is as follows: it includes a base 1, a winding device 2, and a sharpening device 3. The winding device 2 is configured in two groups and installed at intervals on the base 1. One group of the winding device 2 is used to release the wire (i.e., to perform the wire release operation), and the other group is used to rewind the wire (i.e., to perform the wire take-up operation). Each group of the winding device 2 is equipped with a wheel drive mechanism, a wire guide mechanism, and a wire position adjustment mechanism. The wheel drive mechanism is used to receive and drive the winding wheel 20 to rotate (understandably, the winding wheel 20 is a conventional I-beam wheel). The wire guide mechanism is... There are multiple first guide wheels 21 for winding the rope and arranged at intervals according to a preset routing path, and at least one of the first guide wheels 21 can be adjusted in position to achieve real-time adjustment of the rope tension and ensure smooth rope routing; the rope posture adjustment mechanism can adjust the rope segment in the initial stage of unwinding or the pre-winding stage to a preset posture to correct the rope posture and significantly improve the routing and winding quality of the rope; the sharpening device 3 is set between the two sets of winding devices 2 to perform double-sided sharpening of the rope, which significantly improves the quality and efficiency of sharpening.

[0030] Explanation: The “initial stage of releasing the line from the reel” mentioned above refers to the initial stage after the line leaves the reel 20; the “pre-winding stage of the line” mentioned above refers to the preparation stage before the line is wound onto the reel 20.

[0031] The following provides a detailed description of the specific structure of the blade-sharpening and rewinding machine described in this application.

[0032] First, regarding the winding device 2.

[0033] Please continue to refer to the appendix. Figure 2 Appendix Figure 4 and attached Figure 6 As shown, in the winding device 2 described in this embodiment, the spool drive mechanism includes a main ejector pin 220, a secondary ejector pin 221, a drive unit A, and a drive unit B. The main ejector pin 220 and the secondary ejector pin 221 are spaced apart and arranged opposite to each other. The drive unit A can drive the main ejector pin 220 to rotate, and the drive unit B can drive the secondary ejector pin 221 to move closer to or away from the main ejector pin 220. Understandably, when the winding reel 20 with the wire wound on it (i.e., the fully loaded winding reel 20) or the unloaded winding reel 20 is placed between the main ejector pin 220 and the auxiliary ejector pin 221, the drive unit B drives the auxiliary ejector pin 221 to move closer to the main ejector pin 220, so that the auxiliary ejector pin 221 and the main ejector pin 220 cooperate to clamp the winding reel 20; subsequently, the drive unit A drives the main ejector pin 220 to rotate, and drives the winding reel 20 and the auxiliary ejector pin 221 to rotate accordingly, thereby realizing the wire feeding or winding operation.

[0034] Furthermore, in this embodiment, the main ejector pin 220 and the secondary ejector pin 221 are installed as follows: Please refer to the appendix. Figure 2 Appendix Figure 4 and attached Figure 6 As shown, the base 1 has two spaced and side-by-side working chambers 10. For ease of description, the side-by-side direction of the two working chambers 10 is defined as the first horizontal direction. The two sets of winding devices 2 correspond one-to-one with the two working chambers 10. Moreover, the main ejector pin 220 and the auxiliary ejector pin 221 in each set of winding devices 2 are spaced apart and opposite to each other in the working chamber 10 along the first horizontal direction. At the same time, the main ejector pin 220 can rotate around its center line, and the auxiliary ejector pin 221 can reciprocate along the first horizontal direction to move closer to or away from the main ejector pin 220.

[0035] Furthermore, in each winding device 2, the main ejector pin 220 is rotatably mounted on the base 1 via a rotating shaft, and the auxiliary ejector pin 221 is mounted on the base 1 via a sliding rotating component. Specifically: ① The rotating shaft is rotatably mounted on the base 1, with one end of the rotating shaft extending into the working chamber 10. The main ejector pin 220 is positioned and sleeved on one end of the rotating shaft. Furthermore, based on the I-beam structure of the winding wheel 20, one end of the rotating shaft can selectively extend slightly beyond the main ejector pin 220 (see appendix). Figure 4 (as shown), or retracted into the main ejector pin 220 (preferred method). Understandably, when one end of the rotating shaft slightly protrudes from the main ejector pin 220, it is required that the diameter of one end of the rotating shaft is smaller than the inner diameter of the winding wheel 20, so that one end of the rotating shaft can freely insert into or detach from the central hole of the winding wheel 20. ② The sliding rotating component can adopt the following implementation structure: it is provided with a slide rod and a rotating shaft A, the slide rod is able to reciprocate along the first horizontal direction and is inserted into the machine base 1 (e.g., a sliding hole is provided in the machine base 1 that extends along the first horizontal direction and is slidably connected to the slide rod), the rotating shaft A is rotatably connected to one end of the slide rod through a bearing, and the end of the rotating shaft A facing away from the slide rod extends into the working chamber 10, and the auxiliary ejector pin 221 is positioned and sleeved on one end of the rotating shaft A. Understandably, the movement of the slide bar enables the secondary ejector pin 221 to reciprocate along the first horizontal direction; the rotating shaft A enables the secondary ejector pin 221 to rotate together with the winding wheel 20 and the main ejector pin 220. Furthermore, since the winding wheel 20 adopts an I-beam structure, one end of the rotating shaft A can also slightly extend beyond the secondary ejector pin 221 (see appendix). Figure 6 As shown), or retracted into the secondary ejector pin 221 (preferred), and the diameter of one end of the rotating shaft A is also smaller than the inner diameter of the winding wheel 20.

[0036] Furthermore, based on the above-described mounting method of the main ejector pin 220 and the auxiliary ejector pin 221, in each group of winding devices 2, the drive unit A and the drive unit B can adopt the following implementation structure: Please refer to the appendix. Figure 4 and attached Figure 6 As shown, the drive unit A is provided with a servo motor 222 positioned on the base 1, two synchronous pulleys respectively fixedly sleeved on the output shaft of the servo motor 222 and the rotating shaft, and a synchronous belt 223 wound around the two synchronous pulleys; the drive unit B is provided with a drive cylinder 224 positioned on the base 1, the piston rod of the drive cylinder 224 is connected to the sliding rotating member (specifically connected to the slide rod), and can drive the sliding rotating member and the secondary ejector pin 221 to reciprocate along the first horizontal direction.

[0037] For further details, please refer to the appendix. Figure 4 and attached Figure 6 As shown, both the main ejector pin 220 and the auxiliary ejector pin 221 adopt a circular disc structure. Correspondingly, the two opposing sides of the main ejector pin 220 and the auxiliary ejector pin 221 are circular disc surfaces, and each circular disc surface has a planar central region and a sloping region extending radially outward from the periphery of the central region. Based on the above structure of the main ejector pin 220 and the auxiliary ejector pin 221, the main ejector pin 220 and the auxiliary ejector pin 221 can cooperate to clamp winding wheels 20 of different sizes, giving the winding wheel drive mechanism excellent compatibility and versatility.

[0038] In addition, to enable the placement of the winding wheel 20 between the main ejector pin 220 and the auxiliary ejector pin 221, or to remove the winding wheel 20, this embodiment also provides a lifting mechanism capable of driving the winding wheel 20 to move up and down within each working chamber 10. For details, please refer to the appendix. Figure 4 and attached Figure 6 As shown, the lifting mechanism includes a carrier 40 and a lifting cylinder 41. The carrier 40 includes a carrier body 400 and a limiting block 401 fixedly disposed on the top surface of the carrier body 400 to support and limit the winding wheel 20. The lifting cylinder 41 is connected to the carrier 40 and can drive the carrier 40 to move up and down. Understandably, the working principle of the lifting mechanism is as follows: taking the winding device 2 performing a wire feeding (or winding) operation as an example, when a person or a robot places the fully loaded (or unloaded) winding wheel 20 onto the carrier 40, the lifting cylinder 41 operates, lifting the winding wheel 20 to a set height position. After the auxiliary ejector pin 221, driven by the drive unit B, cooperates with the main ejector pin 220 to clamp the winding wheel 20, the lifting cylinder 41 drives the carrier 40 to reset. When the winding wheel 20 is in an unloaded (or fully loaded) state, the lifting cylinder 41 drives the carrier 40 to rise until the carrier 40 abuts against the winding wheel 20. After the auxiliary ejector pin 221 separates from the winding wheel 20 under the drive of the drive unit B, the lifting cylinder 41 drives the carrier 40 and the winding wheel 20 to descend together (understandably, because one end of the rotating shaft extends slightly beyond the main ejector pin 220, and combined with the configuration of the limiting block 401, one end of the rotating shaft will not affect the descent of the winding wheel 20), so that the unloaded (or fully loaded) winding wheel 20 can be transferred away manually or by a robot.

[0039] Please continue to refer to the appendix. Figure 2 Appendix Figure 4 To be continued Figure 6As shown, in the winding device 2 described in this embodiment, the installation method of the lead wire mechanism and the rope position adjustment mechanism is as follows: the base 1 is also provided with two mounting plates 11 respectively spanning above the two working chambers 10; the lead wire mechanism and the rope position adjustment mechanism in each group of winding devices 2 are respectively installed on the corresponding mounting plates 11, and the rope position adjustment mechanism is located below the lead wire mechanism and close to the winding wheel 20 built into the working chamber 10, so as to realize the adjustment of the position of the rope segment in the initial stage of unwinding or the pre-winding stage.

[0040] Furthermore, in each group of winding devices 2, the preferred implementation structure of the rope posture adjustment mechanism is as follows: Please refer to the appendix. Figure 2 Appendix Figure 4 and attached Figure 5As shown, the rope posture adjustment mechanism includes an adjustment component 23 and a linear drive module 24. The adjustment component 23 includes a bracket 231 with a threading hole 230 at the bottom, an angle sensor 232 disposed on the bottom of the bracket 231, and a second guide wheel 233 and two third guide wheels 234, each movably mounted on the bracket 231. The second guide wheel 233 is close to the threading hole 230, and the two third guide wheels 234 are arranged side-by-side above the second guide wheel 233, with a gap between the two third guide wheels 234 for the rope to pass through. Understandably, when the rope moves, the rope presses on one of the third guide wheels 234, and the other... The third guide wheel 234 rotates, while the other third guide wheel 234 does not rotate. Furthermore, the second guide wheel 233 and the two third guide wheels 234, while rotating around their own centerline, also exhibit a slight oscillation characteristic. The angle sensor 232 is used to sense the oscillation angle of the second guide wheel 233 (or the third guide wheel 234). The linear drive module 24 (preferably an electric cylinder) is connected to the bracket 231 and can drive the adjustment assembly 23 to reciprocate along the first horizontal direction, thereby adjusting the rope segment located between the threading hole 230 and the winding wheel 20 to a preset position. Understandably, the working principle of the rope position adjustment mechanism is as follows: For ease of description, the winding device 2 for the unwinding operation is defined as winding device A, and the winding device 2 for the winding operation is defined as winding device B. At that time, the rope path is as follows: the rope on the fully loaded winding wheel 20 passes through the thread hole 230, the second guide wheel 233, the third guide wheel 234 and multiple first guide wheels 21 in the winding device A, the sharpening device 3, and multiple first guide wheels 21, third guide wheels 234, second guide wheels 233 and thread hole 230 in the winding device B, and then enters the unloaded winding wheel 20. The angle sensors 232 in winding device A and winding device B respectively monitor the swing angle of the corresponding second guide wheel 233 in real time and transmit it to the PLC controller. The PLC controller calculates the moving speed of the two adjustment components 23 according to the swing angle of the second guide wheel 233, the wire speed, and the working parameters of the electric cylinder (such as motor speed). By controlling the movement of the adjustment components 23, the position and posture of the wire segment (i.e., the wire segment in the initial stage of unwinding or the pre-winding stage) located between the wire hole 230 and the winding wheel 20 are adjusted, thereby correcting the wire path. That is, the adaptive correction effect is achieved, which significantly improves the winding quality.

[0041] Furthermore, in each set of adjustment components 23, the installation method of the second guide wheel 233 and the third guide wheel 234 is as follows: Please refer to the appendix. Figure 5 As shown, a shaft A extending along a first horizontal direction and a shaft B extending along a second horizontal direction are mounted on the bracket 231, the second horizontal direction being perpendicular to the first horizontal direction. The second guide wheel 233 is fitted onto the shaft A with a clearance, and two stop rings A are also positioned on the shaft A, respectively located on both sides of the axial direction of the second guide wheel 233, to stop and limit the second guide wheel 233 in the first horizontal direction; it can be understood that by controlling the gap / distance between the stop rings A and the second guide wheel 233, the second guide wheel 233 can be driven to swing slightly on the shaft A under the pull of the rope. The third guide wheel 234 is fitted onto the shaft B with a gap, and two stop rings B are also positioned on the shaft B, respectively located on both sides of the axial direction of the third guide wheel 234, to stop and limit the third guide wheel 234 in the second horizontal direction; it can also be understood that by controlling the gap / distance between the stop rings B and the third guide wheel 234, the third guide wheel 234 can be driven to swing slightly on the shaft B under the pull of the rope.

[0042] Furthermore, in each set of adjustment components 23, the extension of the center line of the thread hole 230 passes through the gap between the two third guide wheels 234 to meet the requirements for cable routing.

[0043] Furthermore, in each group of the winding devices 2, the lead-in mechanism is also equipped with a position adjustment drive unit. Please refer to the appendix for details. Figure 4 and attached Figure 6 As shown, the position adjustment drive unit includes a drive motor 25 fixedly mounted on the mounting plate 11 and a transmission rod 26 positioned and connected to the output shaft of the drive motor 25. A first guide wheel 21 is rotatably mounted on the transmission rod 26. That is, the position adjustment drive unit can drive the first guide wheel 21 to swing, thereby adjusting the position of the first guide wheel 21 to regulate the tension of the rope. Furthermore, the remaining first guide wheels 21 not mounted to the transmission rod 26 are rotatably mounted on the mounting plate 11.

[0044] Furthermore, depending on the equipment design requirements, the position adjustment drive unit can be configured to be at least one.

[0045] Next, regarding the aforementioned blade-sharpening device 3.

[0046] Please continue to refer to the appendix. Figure 2 and attached Figure 3As shown, the preferred implementation structure of the sharpening device 3 in this embodiment is as follows: it includes a mounting frame 30, multiple lower guide grinding components 31, multiple upper guide grinding components 32, a lifting drive mechanism 33, and an air blowing mechanism 34. The mounting frame 30 is positioned between two mounting plate frames 11. Multiple lower guide grinding components 31 are spaced apart at the lower part of the mounting frame 30 along the first horizontal direction. Each lower guide grinding component 31 has a lower guide rod 310 for winding a wire and a lower sharpening block 311 for sharpening the wire. The upper surfaces of the multiple lower sharpening blocks 311 are flush. Multiple upper guide grinding components 32 are spaced apart at the lower guide grinding components along the first horizontal direction. Above component 31, each of the multiple upper guide grinding components 32 is provided with an upper guide rod 320 for winding the rope and an upper sharpening block 321 for grinding and sharpening the rope. The lower end faces of the multiple upper sharpening blocks 321 are flush. Furthermore, the multiple upper guide grinding components 32 can also move downward relative to the multiple lower guide grinding components 31 under the drive of the lifting drive mechanism 33, so that the lower end faces of the multiple upper sharpening blocks 321 and the upper end faces of the multiple lower sharpening blocks 311 are in contact with the rope surface, thereby achieving double-sided grinding and sharpening of the rope. The air blowing mechanism 34 can blow and sweep the rope passing between the lower end face of the upper sharpening block 321 and the upper end face of the lower sharpening block 311. Understandably, during the winding of the cord, the cord flowing out of the winding device A generally needs to be wound multiple times around the upper guide rod 320 and the lower guide rod 310 before entering the winding device B to ensure the quality of the sharpening. During cord transmission, the upper sharpening block 321 and the lower sharpening block 311 can perform double-sided sharpening of the cord, resulting in high consistency. Furthermore, since the lower guide sharpening assembly 31 and the upper guide sharpening assembly 32 can provide four-corner support for the cord, vibrations during sharpening can be canceled out, ensuring that double-sided sharpening does not interfere with each other, resulting in high efficiency and high quality. In addition, during the sharpening process, the air blowing mechanism 34 starts working, blowing away the dust generated during the sharpening of the cord, ensuring the cleanliness of the cord after sharpening.

[0047] For further details, please refer to the appendix. Figure 3 As shown, each of the lower guide grinding components 31 is also provided with a lower base 312. The lower guide rod 310 extends along the second horizontal direction and is rotatably mounted on the lower base 312. The lower cutting block 311 is vertically and fixedly mounted on the lower base 312. In addition, the plurality of lower bases 312 are also fixedly connected to the lower part of the mounting frame 30 through a lower support plate 35.

[0048] Each of the upper guide grinding components 32 is further provided with an upper base 322. The upper guide rod 320 extends along the second horizontal direction and is rotatably mounted on the upper base 322. The upper sharpening block 321 is vertically and fixedly mounted on the upper base 322. In addition, the multiple upper bases 322 are also connected to the power output end of the lifting drive mechanism 33 through an upper support plate 36.

[0049] Furthermore, the number of the lower guide polishing component 31 and the upper guide polishing component 32 is not the same, and multiple lower guide polishing components 31 and multiple upper guide polishing components 32 are arranged alternately in sequence.

[0050] For further details, please refer to the appendix. Figure 3 As shown, the lifting drive mechanism 33 is equipped with an electric cylinder or a pneumatic cylinder; the air blowing mechanism 34 is equipped with an air nozzle 341 installed next to the mounting bracket 30 via a metal shaped flexible hose 340 (referring to a gooseneck tube). The air nozzle 341 has multiple air holes and is connected to an external air source. It is understood that the air blowing direction of the air nozzle 341 can be manually adjusted to meet the air blowing requirements for wire grinding and sharpening.

[0051] For further details, please refer to the appendix. Figure 3 As shown, this embodiment also includes a collection tank 37 for collecting dust. The installation of the collection tank 37 satisfies the following condition: multiple lower guide polishing components 31 and multiple upper guide polishing components 32 are all projected downwards into the collection tank 37.

[0052] In summary, ① the overall structural design of the rewinding machine described in this embodiment is reasonable, novel, and concise. The various devices / mechanisms work together organically and are highly compatible, effectively achieving: adaptive correction and automatic tension adjustment functions during winding, significantly improving winding quality; and double-sided sharpening during grinding, significantly improving grinding consistency and efficiency. This effectively meets the production needs of wires (such as diamond wire) and has excellent practicality. ② In the rewinding machine, both sets of winding devices can rotate in both directions, meaning each set can be used for both unwinding and rewinding, significantly improving the processing flexibility of the rewinding machine.
