Description

Technical Field

[0001] This invention belongs to the field of screw processing technology and relates to a milling processing device, particularly a screw milling processing device for a masterbatch extruder. Background Technology

[0002] Screws are a common type of component in the mechanical field. The threads of screws are usually made by milling machines. When milling screws with existing technology, the common method is to fix both ends of the screw and rotate it, with a slide in the middle. The milling cutter slides on the slide to complete the milling process.

[0003] A search revealed a Chinese patent document disclosing a rapid screw milling device [Application No.: 201610866230.5; Publication No.: CN 106270823 A]. This rapid screw milling device, when milling a screw, fixes the screw using a clamping structure and passes it through a milling hole. The ball screw rotates, and because the ball screw pair is fixed, it drives the clamping structure to move linearly and slide on a fixed base. The linear motion of the clamping structure causes the milling cutter to move along the screw during the sliding process, allowing the milling cutter to mill the screw. Since the screw is only fixed by the clamping structure, there is no deformation due to forces at both ends. The ball screw pair converts rotational motion into linear motion, thus enabling the clamping structure to move linearly so that the milling cutter can complete the milling work. Furthermore, the ball screw pair can achieve micro-feed, resulting in accurate milling cutter positioning and high-quality screw milling.

[0004] Although this patent allows the fixture structure to move linearly so that the milling cutter can complete the milling work, and the ball screw pair can achieve micro-feed, thus ensuring accurate milling cutter positioning and high-quality milling of the screw, it is necessary to clean the surface debris in time when milling the screw. Otherwise, it will affect the machining accuracy, damage the equipment, and even bring safety hazards. This application cannot clean the debris on the screw surface during the milling process. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a screw milling device for a masterbatch extruder. The technical problem this invention aims to solve is: how to clean debris from the screw surface and process and recycle the debris.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A screw milling device for a masterbatch extruder includes a base, a mounting seat fixed on the base, and a processing frame fixed on the mounting seat. The processing frame has a processing cavity and a limit frame. A mounting arm is slidably connected to the base, and a drive frame is fixed to the top of the mounting arm. A drive disc is rotatably connected to the drive frame and fixedly connected to the limit frame. A limit arm is slidably connected to the limit frame, and a limit seat is fixed to one end of each limit arm and the limit frame. Each limit seat has a clamping component for clamping and fixing the workpiece. A drive component for controlling the extension of the limit arm is provided inside the limit arm. A scrap discharge port is provided in the mounting seat, the top of which connects to the processing cavity. A pair of scrap screws are rotatably connected to the scrap discharge port, and the mounting seat has a control mechanism for the two scrap screws. The screw is driven by a second drive assembly, and a blower frame is fixed on the processing frame. The blower frame has multiple blowing ports that connect to the processing chamber. Each blowing port has a fixed mounting bracket, and each mounting bracket is rotatably connected to a blowing impeller. The blower frame also contains a third drive assembly that controls the operation of each blowing impeller. A drive motor is fixed inside the drive frame, and the output shaft of the drive motor is coaxially fixedly connected to the drive disk. An external gear ring is rotatably connected inside the processing frame, and a pair of plug-in blocks are fixed on the external gear ring. The drive disk has a pair of plug-in slots, and each plug-in block is plugged into the corresponding plug-in slot. Both the second and third drive assemblies are poweredly connected to the external gear ring. An adjustment frame is slidably connected to the processing frame, and a milling frame is slidably mounted on the adjustment frame. A milling assembly is mounted on the milling frame.

[0008] The working principle of this invention is as follows: The workpiece is placed between two limiting seats. The extension of the limiting arms is controlled by a drive assembly, causing the two limiting seats to clamp and limit both ends of the workpiece. The limiting components on each limiting seat further secure the workpiece, preventing it from falling off during processing and improving overall operational stability. The workpiece is then milled by a milling assembly. Debris falling during processing enters the waste discharge port. After milling, a drive motor rotates the drive disc, which in turn drives the entire... The workpiece rotates, which throws out residual debris for cleaning. Because the connecting blocks engage with their corresponding slots, the drive disc synchronously drives the external gear ring to rotate. The external gear ring then drives drive assembly two and drive assembly three. Drive assembly two, in turn, drives each impeller to rotate, which in turn blows onto the workpiece, further improving the cleaning effect. Drive assembly three, through the rotation of the two crushing screws, processes the debris, ensuring it is crushed evenly and improving the subsequent recycling process.

[0009] The drive assembly includes a control screw rotatably connected inside the limit arm and a servo motor fixed inside the limit arm. The output shaft of the servo motor is coaxially fixedly connected to the control screw, and the control screw is threadedly connected to the limit frame.

[0010] With the above structure, a servo motor can drive the control screw to rotate, and the rotation of the control screw will drive the limit arm to move, thereby adjusting the extension of the limit arm and achieving the clamping effect on the workpiece.

[0011] The clamping assembly includes a pair of clamping arms slidably connected within each limiting seat, and a bidirectional lead screw rotatably connected within each limiting seat. A transmission gear 1 is coaxially fixedly connected to each bidirectional lead screw. A servo motor 2 is fixed within each limiting seat. The output shaft of each servo motor 2 is coaxially fixedly connected to a transmission gear 2. Each transmission gear 2 meshes with a corresponding transmission gear 1. The bottom end of each pair of clamping arms is threaded to the threaded section of the corresponding bidirectional lead screw, and anti-slip pads are fixed to the opposite surfaces of the top ends of each pair of clamping arms.

[0012] With the above structure, the second servo motor can drive the second transmission gear to rotate, which in turn drives the corresponding first transmission gear to rotate. The rotation of the first transmission gear will then drive the bidirectional lead screw to rotate, which in turn will drive the corresponding clamping arm to perform a clamping action, thereby achieving further clamping of the workpiece end.

[0013] The second drive assembly includes a drive gear 1 rotatably connected within the mounting base, and a drive bevel gear 1 coaxially fixedly connected to the drive gear 1. A pair of reciprocating screws are rotatably connected within the mounting base, and a drive bevel gear 2 is coaxially fixedly connected to each reciprocating screw. Each drive bevel gear 2 meshes with the drive bevel gear 1. A movable block is threaded onto each reciprocating screw, and a gear rack is fixed to the bottom of each movable block. A pair of control gears are rotatably connected within the mounting base, and each control gear is coaxially fixedly connected to a corresponding crushing screw. Each control gear meshes with a corresponding gear rack, and the drive gear 1 meshes with an external gear ring.

[0014] With the above structure, the external gear ring drives the first drive gear to rotate. The rotation of the first drive gear drives the first drive bevel gear to rotate, which in turn drives the corresponding second drive bevel gear to rotate. The rotation of the second drive bevel gear drives the corresponding reciprocating screw to rotate. The rotation of the reciprocating screw drives the movable block to move back and forth. During the movement of the movable block, the rack moves synchronously. During the reciprocating left and right movement of the rack, the control gear rotates back and forth, further realizing the alternating forward and backward movement of the two crushing screws. This can "loosen" the material block, smooth the material peak, reduce bridging and dead zones, stabilize the conveying, and reduce the risk of jamming.

[0015] The drive assembly includes a drive wheel rotatably connected inside the blower frame, multiple guide grooves arranged in a ring on the drive wheel, a toothed block slidably connected in each guide groove, a push spring fixed between each toothed block and the bottom of the corresponding guide groove, and each toothed block meshing with an outer gear ring. A drive worm gear is rotatably connected inside each mounting bracket, and each drive worm gear is coaxially fixedly connected to a corresponding blowing impeller. A drive worm is rotatably connected inside the blower frame, meshing with each drive worm gear, and the drive worm can only rotate in one direction. The drive worm is coaxially fixedly connected to the drive wheel. Dustproof nets are fixed at both ends of each blowing port.

[0016] With the above structure, the meshing of the external gear ring and the gear block causes the external gear ring to rotate, which in turn drives the drive wheel to rotate. The drive wheel then drives the drive worm to rotate, which in turn drives multiple drive worm wheels to rotate synchronously. Each drive worm wheel then drives a corresponding blowing impeller to perform the blowing operation. The drive worm is restricted to unidirectional rotation, meaning that normal blowing can only be achieved when the external gear ring rotates in the direction that the blowing impeller can blow onto the workpiece. When the external gear ring rotates in the opposite direction, the gear block retracts due to the simultaneous restriction of the drive worm and the external gear ring, thus disengaging from the external gear ring.

[0017] The milling assembly includes a servo motor three fixed inside the milling frame, a milling cutter head coaxially fixedly connected to the output shaft of the servo motor three, a drive screw one rotatably connected inside the adjustment frame, the drive screw one being threadedly connected to the milling frame, and a servo motor four fixed on the adjustment frame, the output shaft of the servo motor four being coaxially fixedly connected to the drive screw one.

[0018] With the above structure, the milling cutter head can be rotated by servo motor three to realize milling work, and then the drive screw one can be rotated by servo motor four. After the drive screw one rotates, it will drive the milling head to move up and down, thereby controlling the milling depth.

[0019] A servo motor five is fixed inside the base, and a drive screw two is rotatably connected inside the base. The drive screw two is threadedly connected to the mounting arm, and the output shaft of the servo motor five is coaxially fixedly connected to the drive screw two.

[0020] With the above structure, the servo motor five drives the drive screw two to rotate. After the drive screw rotates, it will drive the mounting arm to move, thereby controlling the mounting arm to unfold or retract. After the mounting arm unfolds, the structure that fixes the workpiece can be extended from the machining cavity, improving the overall efficiency of workpiece assembly and disassembly. After the mounting arm retracts, it will drive the mounted workpiece into the machining cavity for milling.

[0021] The base has a waste material extrusion chamber, which is connected to the bottom end of the waste material discharge port. An extrusion screw is rotatably connected inside the waste material extrusion chamber. A servo motor is fixed inside the base, and the output shaft of the servo motor is coaxially fixedly connected to the extrusion screw. The base has a waste material outlet that connects to the waste material extrusion chamber.

[0022] With the above structure, the extrusion screw can be driven to rotate by the servo motor. After the extrusion screw rotates, it will drive the crushed debris to be extruded and conveyed. During the conveying process, the debris will be further crushed and sheared.

[0023] A servo motor 7 is fixed inside the processing frame, and a drive screw 3 is rotatably connected inside the processing frame. The drive screw 3 is threadedly connected to the adjustment frame, and the output shaft of the servo motor 7 is coaxially fixedly connected to the drive screw 3.

[0024] With the above structure, the control screw three can be rotated by the servo motor seven. After the control screw three rotates, it will drive the adjustment frame to move, and the movement of the adjustment frame will increase the milling range.

[0025] Compared with existing technologies, the screw milling processing device for natural masterbatch extruders has the following advantages:

[0026] 1. After milling, the drive motor drives the drive disk to rotate, which in turn drives the entire workpiece to rotate. The rotating workpiece throws out and cleans the residual debris.

[0027] 2. After milling, each impeller will blow on the workpiece after rotating, further improving the cleaning effect.

[0028] 3. After milling, the two crushing screws rotate after the drive component three operates, so that the debris can be crushed evenly and the effect of subsequent recycling is improved. Attached Figure Description

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] like Figures 1-9 As shown, a screw milling processing device for a masterbatch extruder includes a base 1, a mounting seat 2 fixed on the base 1, a processing frame 3 fixed on the mounting seat 2, a processing cavity 4 inside the processing frame 3, a limit frame 5 inside the processing frame 3, a mounting arm 6 slidably connected inside the base 1, a drive frame 7 fixed to the top of the mounting arm 6, a drive disc 8 rotatably connected to the drive frame 7, the drive disc 8 being fixedly connected to the limit frame 5, and a limit arm 9 slidably connected to the limit frame 5. A limit seat 10 is fixed to one end of the limit arm 9 and the limit frame 5, and each limit seat 10 is provided with a clamping component for clamping and fixing the workpiece. A drive component for controlling the extension degree of the limit arm 9 is provided inside the limit arm 9. A scrap discharge port 11 is opened inside the mounting seat 2, the top of the scrap discharge port 11 communicating with the processing cavity 4, and a pair of scrap screws 12 rotatably connected inside the scrap discharge port 11. A control mechanism for the operation of the two scrap screws 12 is provided inside the mounting seat 2. The second drive component is provided, and a blower frame 14 is fixed on the processing frame 3. The blower frame 14 has multiple blowing ports 15 that connect to the processing chamber 4. Each blowing port 15 has a fixed mounting frame 16. Each mounting frame 16 is rotatably connected to a blowing impeller 17. The blower frame 14 is provided with a third drive component that controls the operation of each blowing impeller 17. The drive frame 7 is provided with a drive motor 18. The output shaft of the drive motor 18 is coaxially fixedly connected to the drive disk 8. An external gear ring 19 is rotatably connected in the processing frame 3. A pair of plug-in blocks 20 are fixed on the external gear ring 19. A pair of plug-in slots 21 are provided on the drive disk 8. Each plug-in block 20 is plugged into the corresponding plug-in slot 21. The second and third drive components are both poweredly connected to the external gear ring 19. An adjustment frame 22 is slidably connected in the processing frame 3. A milling frame 23 is slidably mounted on the adjustment frame 22. A milling component is mounted on the milling frame 23.

[0041] The workpiece can be placed between two limiting seats 10. The extension of the limiting arm 9 is controlled by the drive component, so that the two limiting seats 10 clamp and limit both ends of the workpiece. Then, the limiting components on each limiting seat 10 further fix the workpiece to prevent it from falling off during processing and improve the overall operational stability. The workpiece is then milled by the milling component. The debris that falls off during processing will enter the debris drop outlet 11. After milling is completed, the drive motor 18 drives the drive disk 8 to rotate, and the rotation of the drive disk 8 will drive the entire workpiece to rotate. The workpiece is rotated to remove residual debris. Since the plug-in blocks 20 are engaged with the corresponding plug-in slots 21, the drive disc 8 synchronously drives the outer gear ring 19 to rotate. The outer gear ring 19 drives the second and third drive components to operate. After the second drive component operates, it drives each blowing impeller 17 to rotate. Each blowing impeller 17 blows the workpiece, further improving the cleaning effect. Then, after the third drive component operates, the two crushing screws 12 rotate to process the debris, so that the debris can be crushed evenly, improving the effect of subsequent recycling.

[0042] The drive assembly includes a control screw 24 rotatably connected inside the limit arm 9 and a servo motor 25 fixed inside the limit arm 9. The output shaft of the servo motor 25 is coaxially fixedly connected to the control screw 24, and the control screw 24 is threadedly connected to the limit frame 5.

[0043] With the above structure, the control screw 24 can be rotated by the servo motor 25. After the control screw 24 rotates, it will drive the limit arm 9 to move, thereby adjusting the extension degree of the limit arm 9 and achieving the clamping effect on the workpiece.

[0044] The clamping assembly includes a pair of clamping arms 26 slidably connected within each limit seat 10, a bidirectional lead screw 27 rotatably connected within each limit seat 10, a transmission gear 28 coaxially fixedly connected to each bidirectional lead screw 27, a servo motor 29 fixedly fixed within each limit seat 10, a transmission gear 30 coaxially fixedly connected to the output shaft of each servo motor 29, each transmission gear 30 meshing with the corresponding transmission gear 28, the bottom end of each pair of clamping arms 26 being threadedly connected to the threaded section of the corresponding bidirectional lead screw 27, and anti-slip pads 31 fixedly on the opposite surfaces of the top ends of each pair of clamping arms 26.

[0045] With the above structure, the servo motor 29 drives the transmission gear 30 to rotate, the transmission gear 30 drives the corresponding transmission gear 28 to rotate, the transmission gear 28 rotates and drives the bidirectional lead screw 27 to rotate, the bidirectional lead screw 27 rotates and drives the corresponding clamping arm 26 to perform clamping action, thereby realizing further clamping action on the end of the workpiece.

[0046] The second drive assembly includes a drive gear 32 rotatably connected within the mounting base 2, a drive bevel gear 33 coaxially fixedly connected to the drive gear 32, a pair of reciprocating screws 34 rotatably connected within the mounting base 2, a drive bevel gear 35 coaxially fixedly connected to each reciprocating screw 34, each drive bevel gear 35 meshing with the drive bevel gear 33, a movable block 36 threadedly connected to each reciprocating screw 34, a rack 37 fixedly attached to the bottom of each movable block 36, a pair of control gears 38 rotatably connected within the mounting base 2, each control gear 38 coaxially fixedly connected to the corresponding crushing screw 12, and each control gear 38 meshing with the corresponding rack 37, and the drive gear 32 meshing with the outer gear ring 19.

[0047] With the above structure, the external gear ring 19 drives the drive gear 32 to rotate. After the drive gear 32 rotates, it drives the drive bevel gear 33 to rotate. After the drive bevel gear 33 rotates, it drives the corresponding drive bevel gear 35 to rotate. After the drive bevel gear 35 rotates, it drives the corresponding reciprocating screw 34 to rotate. After the reciprocating screw 34 rotates, it drives the movable block 36 to move back and forth. During the movement of the movable block 36, it drives the rack 37 to move synchronously. During the reciprocating left and right movement of the rack 37, it drives the control gear 38 to rotate back and forth. This further realizes the reciprocating alternation of the two crushing screws 12 forward and backward, which can "loosen" the material block, smooth the material peak, reduce bridging and dead zone phenomena, stabilize the conveying, and reduce the risk of jamming.

[0048] The drive assembly includes a drive wheel 39 rotatably connected inside the blower frame 14, and multiple guide grooves 40 arranged in a ring on the drive wheel 39. Each guide groove 40 is slidably connected to a toothed block 41, and a push spring 42 is fixed between each toothed block 41 and the bottom of the corresponding guide groove 40. Each toothed block 41 meshes with an outer gear ring 19. Each mounting bracket 16 is rotatably connected to a drive worm gear 43, and each drive worm gear 43 is coaxially fixedly connected to a corresponding blowing impeller 17. A drive worm 44 is rotatably connected inside the blower frame 14, and the drive worm 44 meshes with each drive worm gear 43. The drive worm 44 can only rotate in one direction and is coaxially fixedly connected to the drive wheel 39. Dustproof nets 45 are fixed at both ends of each blowing port 15.

[0049] With the above structure, the meshing of the external gear ring 19 and the gear block 41 causes the external gear ring 19 to rotate, which in turn drives the drive wheel 39 to rotate. The drive wheel 39 then drives the drive worm 44 to rotate, which in turn drives multiple drive worm wheels 43 to rotate synchronously. Each drive worm wheel 43 then drives the corresponding blowing impeller 17 to perform blowing work. The drive worm 44 is restricted to unidirectional rotation, meaning that normal blowing work can only be achieved when the external gear ring 19 rotates in the direction that allows the blowing impeller 17 to blow on the workpiece. When the external gear ring 19 rotates in the opposite direction, the gear block 41 retracts due to the simultaneous restriction of the drive worm 44 and the external gear ring 19, thus disengaging from the meshing state with the external gear ring 19.

[0050] The milling assembly includes a servo motor 46 fixed inside the milling frame 23, a milling cutter disc 47 coaxially fixedly connected to the output shaft of the servo motor 46, a drive screw 48 rotatably connected inside the adjusting frame 22, the drive screw 48 being threadedly connected to the milling frame 23, and a servo motor 49 fixed on the adjusting frame 22, the output shaft of the servo motor 49 being coaxially fixedly connected to the drive screw 48.

[0051] With the above structure, the milling cutter head 47 can be rotated by the servo motor 3 46 to realize the milling work, and the drive screw 48 can be rotated by the servo motor 49. After the drive screw 48 rotates, it will drive the milling frame 23 to move up and down, thereby controlling the milling depth.

[0052] A servo motor 50 is fixed inside the base 1, and a drive screw 51 is rotatably connected inside the base 1. The drive screw 51 is threadedly connected to the mounting arm 6, and the output shaft of the servo motor 50 is coaxially fixedly connected to the drive screw 51.

[0053] With the above structure, the servo motor 50 drives the drive screw 2 51 to rotate. After the drive screw rotates, it will drive the mounting arm 6 to move, thereby controlling the mounting arm 6 to unfold or retract. After the mounting arm 6 unfolds, the structure that fixes the workpiece can be extended from the machining cavity 4, improving the overall efficiency of workpiece assembly and disassembly. After the mounting arm 6 retracts, it will drive the installed workpiece into the machining cavity 4 for milling.

[0054] The base 1 has a waste material extrusion chamber 52, which is connected to the bottom end of the waste material drop outlet 11. An extrusion screw 53 is rotatably connected inside the waste material extrusion chamber 52. A servo motor 6 54 is fixed inside the base 1. The output shaft of the servo motor 6 54 is coaxially fixedly connected to the extrusion screw 53. The base 1 has a waste material outlet 55 that connects to the waste material extrusion chamber 52.

[0055] With the above structure, the extrusion screw 53 can be rotated by the servo motor 6 54. After the extrusion screw 53 rotates, it will drive the crushed debris to be extruded and conveyed. During the conveying process, the debris will be further crushed and sheared.

[0056] A servo motor 7 56 is fixed inside the processing frame 3. A drive screw 3 57 is rotatably connected inside the processing frame 3. The drive screw 3 57 is threadedly connected to the adjustment frame 22, and the output shaft of the servo motor 7 56 is coaxially fixedly connected to the drive screw 3 57.

[0057] Using the above structure, the control screw 24 can be rotated by the servo motor 756. After the control screw 24 rotates, it will drive the adjustment frame 22 to move. After the adjustment frame 22 moves, the milling range will be increased.

[0058] The working principle of this invention is as follows: The workpiece is placed between two limiting seats 10. A servo motor 25 drives a control screw 24 to rotate, which in turn moves the limiting arm 9, adjusting its extension and thus clamping the workpiece. A servo motor 29 drives a transmission gear 30 to rotate, which in turn drives a corresponding transmission gear 28 to rotate. This rotation of the transmission gear 28 then drives a bidirectional lead screw 27 to rotate, which in turn drives a corresponding clamping arm 26 to perform a clamping action, further clamping the end of the workpiece. Finally, a servo motor 50 drives a drive screw 51 to rotate, further clamping the workpiece. After rotation, the mounting arm 6 will move, and after the mounting arm 6 retracts, it will bring the mounted workpiece into the machining cavity 4 for milling. Servo motor 3 46 drives the milling cutter disc 47 to rotate, realizing the milling operation. Servo motor 49 then drives the drive screw 48 to rotate, which in turn moves the milling frame 23 up and down to adjust the milling depth. Servo motor 7 56 drives the adjusting screw 24 to rotate, which in turn moves the adjusting frame 22, increasing the milling range. After milling is completed, drive motor 18 drives the drive disk 8 to rotate, which in turn rotates the entire workpiece. The rotating workpiece removes residual debris, and because the insert blocks 20 are engaged with the corresponding insert slots 21, the drive disc 8 synchronously drives the external gear ring 19 to rotate. The external gear ring 19 drives the drive gear 32 to rotate, which in turn drives the drive bevel gear 33 to rotate. The drive bevel gear 33 then drives the corresponding drive bevel gear 35 to rotate, which in turn drives the corresponding reciprocating screw 34 to rotate. The reciprocating screw 34 then drives the movable block 36 to move back and forth. During the movement of the movable block 36, the rack 37 moves synchronously. During the reciprocating left and right movement of the rack 37, the control gear 38 reciprocates left and right. The rotation further enables the two crushing screws 12 to alternately advance and retract, which can "loosen" material plugs, smooth material peaks, reduce bridging and dead zones, stabilize conveying, and reduce the risk of jamming. The meshing of the external gear ring 19 and the toothed block 41 causes the external gear ring 19 to rotate, which in turn drives the drive wheel 39 to rotate. The drive wheel 39 then drives the drive worm 44 to rotate, which in turn drives multiple drive worm wheels 43 to rotate synchronously. Each drive worm wheel 43, upon rotation, drives the corresponding blowing impeller 17 to perform the blowing action. The rotation of the drive worm 44 is restricted to one direction only; that is, the blowing action of the blowing impeller 17 on the workpiece can only be achieved when the external gear ring 19 rotates in that direction.To achieve normal blowing operation, when the outer gear ring 19 rotates in the reverse direction, the tooth block 41 retracts due to the simultaneous restriction of the driving worm gear 44 and the outer gear ring 19, thus disengaging from the meshing state with the outer gear ring 19. After the debris is broken up, the electric gate 13 is opened, allowing the debris to fall into the debris extrusion chamber 52. The servo motor 54 drives the extrusion screw 53 to rotate, and the rotation of the extrusion screw 53 will drive the crushed debris to be extruded and conveyed. During the conveying process, the debris is further crushed and sheared.

[0059] In summary, by placing the workpiece between the two limiting seats 10, the extension of the limiting arm 9 is controlled by the drive component, thereby clamping and limiting both ends of the workpiece by the two limiting seats 10. The limiting components on each limiting seat 10 further secure the workpiece, preventing it from falling off during processing and improving overall operational stability. The workpiece is then milled by the milling component. During processing, debris falls into the debris dropper 11. After milling, the drive motor 18 drives the drive disk 8 to rotate, which in turn rotates the entire workpiece. The rotating mechanism removes residual debris from the workpiece by rotating it. Since the insertion blocks 20 are engaged with the corresponding insertion slots 21, the drive disc 8 synchronously drives the outer gear ring 19 to rotate. The outer gear ring 19 then drives drive assembly two and drive assembly three to operate. Drive assembly two, in turn, drives each blowing impeller 17 to rotate. Each blowing impeller 17 blows onto the workpiece, further improving the cleaning effect. Drive assembly three, through the rotation of the two crushing screws 12, processes the debris, ensuring uniform crushing and improving the subsequent recycling process.
