TECHNICAL FIELD
[0001] The present application relates to the technical field of cutter cleaning, and in particular to a cutter cleaning machine. BACKGROUND
[0002] In the PCB industry, as a key production equipment, the cutter is an important component of the numerical control drilling machine. The cutter is generally made of ABS plastic and has certain strength and durability, mainly used for fixing and supporting the drill needle to ensure the stability and accuracy of the drill needle during work, thereby ensuring the quality and precision of PCB drilling.
[0003] With the demand of the new drill needle intelligence system, the existing large number of old cutters need to be coded. The coding position is located at the edge of the cutter close to the cutter handle, a 54mm*10mm area. When the original life control is used, the position needs to be coded by artificial marking with a paint pen, which makes the position to be coded dirty.
[0004] Therefore, the position to be coded needs to be cleaned to remove the original mark. One of the existing cleaning methods is to use a solvent (such as open oil water) to manually remove dirt, but such a solvent is not only toxic and harmful to personnel health, but also highly flammable, which poses a safety hazard. Moreover, the cleaning method using solvent also has other disadvantages, such as the solvent dosage is difficult to control, too much solvent will dissolve the base plastic of the cutter, affecting the structure of the cutter, and too little solvent cannot quickly remove the paint pen marks, resulting in low cleaning efficiency. If the solvent cleaning method is automated according to this idea, the improved method still needs to face the problems of environmental exhaust, electrical equipment explosion-proof, sewage treatment, etc., which is high in cost and difficult to implement. Therefore, a cleaning method is needed to solve the problems of high cleaning difficulty, high danger level and high cleaning pollution level in the existing cleaning method. SUMMARY

[0036] As shown in Figures 1 to 6 Fig. 1, the present application provides a cutter cleaning machine 1 for cleaning a cutter 200, which comprises:
[0037] A conveyor belt 10, which is used for conveying the cutter 200;
[0038] A pressing plate assembly 20, which is movably connected above the conveyor belt 10, and can move towards or away from the conveyor belt 10 to press or release the cutter 200;
[0039] A polishing assembly 30 is mounted on the pressing plate 25, and the polishing assembly 30 comprises a first driving member 31 and a polishing member 33. The polishing member 33 is located above the conveying belt 10, and the first driving member 31 is drivingly connected to the polishing member 33 to drive the polishing member 33 to rotate. The polishing member 33 is used to clean the cutter head 200. The pressing plate assembly 20 moves to drive the polishing assembly 30 to move.
[0040] A dust suction assembly 40 is located above the polishing member 33, and a dust suction port of the dust suction assembly 40 is arranged to face the polishing member 33.
[0041] The cutter head cleaning machine 1 comprises the conveying belt 10, the pressing plate assembly 20, the polishing assembly 30 and the dust suction assembly 40. The conveying belt 10 is responsible for conveying the cutter head 200 and is a basic component for realizing an automatic cleaning process. The pressing plate assembly 20 can be moved to press against or be separated from the cutter head 200, so as to ensure that the cutter head 200 is stable in position during cleaning and to ensure the accuracy of cleaning. The polishing assembly 30 is mounted on the pressing plate 25. The first driving member 31 drives the polishing member 33 to rotate to realize a cleaning function. The polishing assembly 30 is used to clean the code assignment position of the cutter head 200 and avoids damaging other parts of the cutter head 200. The dust suction assembly 40 is located above the polishing member 33, and a dust suction port of the dust suction assembly 40 is arranged to face the polishing member 33. The dust suction assembly 40 can timely suck away debris generated during cleaning, so as to prevent pollution and equipment failure. These components work cooperatively to constitute the core architecture of the cutter head cleaning machine 1.
[0042] In actual operation, first, the cutter head 200 to be cleaned is placed at the starting end of the conveying belt 10. The conveying belt 10 is started to run and convey the cutter head 200 to the cleaning area. At this time, the pressing plate assembly 20 is moved to lower the pressing plate 25 to press against the cutter head 200 and fix the position of the cutter head 200. Then, the first driving member 31 drives the polishing member 33 to rotate at a high speed to clean the code assignment area of the cutter head 200. The dust suction assembly 40 works synchronously to suck away debris generated during cleaning. After cleaning is completed, the pressing plate assembly 20 releases the cutter head 200, and the conveying belt 10 sends the cleaned cutter head 200 out of the cleaning area. The cutter head 200 can be taken out of the conveying belt 10 by manual operation or a feeding mechanism.
[0043] Optionally, the conveying belt 10 can be made of rubber material, which has good flexibility and wear resistance and can adapt to long-time conveying work of the cutter head 200. In addition, the conveying belt 10 can be driven by a motor. The power of the motor can be selected according to the load capacity and running speed requirement of the conveying belt 10. The motor is connected to the driving shaft of the conveying belt 10 through a speed reduction device to realize stable power transmission and ensure that the conveying belt 10 runs at a suitable speed.
[0044] Optionally, the pressing plate assembly 20 can be a combination of a spring and the pressing plate 25, a combination of the optical shaft 23 and the pressing plate 25, or a combination of a sliding rail and a sliding block and the pressing plate 25.
[0045] Optionally, the first drive unit 31 can be a DC motor or an AC variable frequency motor. DC motors offer convenient speed adjustment to meet various cleaning needs; AC variable frequency motors, on the other hand, have the advantages of energy saving and stable operation. The motor is connected to the polishing part 33 via belt drive or a coupling to ensure efficient power transmission.
[0046] Optionally, the vacuuming assembly 40 includes a vacuum cleaner and a vacuum pipe. The vacuum cleaner can be an industrial-grade cyclone vacuum cleaner or a bag vacuum cleaner. Cyclone vacuum cleaners are effective at separating larger particles of debris, quickly sucking most of the debris into the dust collection bin; bag vacuum cleaners are better at filtering fine dust, ensuring that the exhaust air is clean and unpolluted. The vacuum pipe is made of plastic or metal, such as PVC plastic or galvanized steel pipe. The diameter of the vacuum pipe is between 30 and 50 mm, and it must be smooth internally to reduce airflow resistance and ensure that debris can be smoothly sucked into the vacuum cleaner. The shape of the suction port can be circular or rectangular, and needs to be designed according to the size and shape of the polished part 33 to ensure that the suction port can cover the polishing area and effectively remove the generated debris.
[0047] Optionally, the dust collection component 40 can also be an electrostatic dust collection component 40, which utilizes the principle of electrostatic adsorption to set up an electrostatic field inside the dust collection pipe, causing debris to become charged as it passes through and be adsorbed onto the electrode plates. This dust collection method is more effective at collecting fine dust and lightweight debris, and can effectively improve dust collection efficiency and air quality.
[0048] Optionally, the vacuuming assembly 40 can also be a water curtain vacuuming assembly 40. By setting a water curtain near the vacuum port, when debris is sucked in, it is first washed by the water curtain, carrying dust and debris into the water. Then, the wastewater is discharged and treated through a water circulation system. Water curtain vacuuming can effectively capture and collect large amounts of dust and debris, while also playing a role in cooling and fire prevention.
[0049] Furthermore, the conveyor belt 10 is provided with a plurality of baffles 11, which are connected to the conveyor belt 10 along a direction perpendicular to the extension of the conveyor belt 10. The plurality of baffles 11 are spaced apart, and a receiving space is formed between two adjacent baffles 11. The receiving space is used to place a cutter head 200.
[0050] Specifically, the conveyor belt 10 is provided with multiple baffles 11, which are connected along a direction perpendicular to the extension of the conveyor belt 10 and spaced apart to form a receiving space for placing the cutter disc 200. This structural design allows the cutter disc 200 to be orderly separated and fixed during the conveying process, preventing displacement or collision of the cutter disc 200 during transport, and further ensuring the stability and accuracy of the cutter disc 200 transport. Compared with a conveyor belt 10 without baffles 11, it can better adapt to the automated process of cleaning the cutter disc 200, improving the reliability and working efficiency of the cleaning machine.
[0051] Optionally, the baffle 11 can be made of plastic or rubber. Plastic baffles 11, such as ABS plastic, have a certain strength and toughness and are not easily deformed; rubber baffles 11 have better cushioning performance and can prevent damage to the cutter head 200 when it collides with the baffle 11. The thickness of the baffle 11 is between 3 and 8 mm, and its height is determined according to the thickness of the cutter head 200, generally 10 to 20 mm higher than the thickness of the cutter head 200, ensuring that the cutter head 200 is stably placed within the receiving space and will not fall out.
[0052] Optionally, the baffles 11 are fixed to the conveyor belt 10 by welding, riveting, or bolting. Welding provides a strong connection but is difficult to disassemble; riveting is relatively simple but the connection strength is slightly weaker; bolting facilitates installation and maintenance, and the choice can be made according to actual needs. The distance between adjacent baffles 11 is determined based on the diameter of the cutter head 200, and is generally 5-10 mm larger than the diameter of the cutter head 200 to ensure that the cutter head 200 can be smoothly placed into the accommodating space without being too loose and causing wobbling.
[0053] Furthermore, the conveyor belt 10 is a circulating baffle conveyor belt.
[0054] In this embodiment, the conveyor belt 10 has a circulating structure, which enables the conveyor belt 10 to run continuously. During the cleaning process of the cutter disc 200, when one cutter disc 200 is cleaned and sent out, a new cutter disc 200 can quickly enter the cleaning position without the need for frequent manual intervention to reposition the cutter disc 200. This greatly improves the continuity and efficiency of cleaning, reduces equipment downtime, and is a further optimization and improvement of the function of the conveyor belt 10, enhancing the practicality of the cleaning machine in batch cutter disc 200 cleaning operations.
[0055] Furthermore, the circulating baffle conveyor belt includes a drive wheel and a tensioning device. The drive wheel is made of metal, such as carbon steel or stainless steel, and its surface is hardened to improve hardness and wear resistance. The drive wheel is mounted on the equipment frame via bearings, specifically deep groove ball bearings, which can withstand certain radial and axial loads, ensuring flexible rotation of the drive wheel. The tensioning device can be a screw-type tensioning device or a counterweight-type tensioning device. The screw-type tensioning device adjusts the tension of the conveyor belt 10 by rotating the screw, which is convenient to operate and has high adjustment accuracy; the counterweight-type tensioning device automatically maintains the tension of the conveyor belt 10 using the weight of the counterweight, which has high reliability. The tensioning device is installed on one side of the driven wheel of the conveyor belt 10, and the tension is adjusted reasonably according to the length of the conveyor belt 10 and the running conditions to ensure that the conveyor belt 10 does not become loose or deviate during circulating operation.
[0056] Alternatively, the conveyor belt 10 can also be a chain conveyor belt, using a metal chain as the transmission component, with a specially designed tray mounted on the chain to hold the cutter head 200. The tray can be welded or bolted to the chain links to ensure stability. The advantage of this structure is its high load-bearing capacity, making it suitable for heavier cutter heads 200 or for operation in harsh environments, such as where dust or debris may affect the normal operation of the rubber conveyor belt 10. Compared to the belt conveyor belt 10, the chain conveyor belt has a longer service life, but may generate more noise, requiring appropriate noise reduction measures, such as installing soundproof covers or using special chain lubrication methods to reduce noise.
[0057] Alternatively, the conveyor belt 10 can also be a magnetic conveyor belt, with magnetic material embedded on its surface or inside. The cutter head 200 is made of a magnetically attractive material or has magnetic attachments installed at its bottom. During conveying, the cutter head 200 is magnetically attached to the conveyor belt 10 without the need for an additional baffle 11 for fixation. The advantage of this design is that it simplifies the structure, reduces the number of parts, and lowers equipment costs and maintenance difficulty. However, it places certain requirements on the material of the cutter head 200, and the magnetic strength needs to be precisely controlled to ensure that the cutter head 200 can be stably attached and easily removed from the conveyor belt 10.
[0058] Furthermore, polishing component 33 is a scouring pad polishing wheel.
[0059] In this embodiment, the scouring pad material has a certain abrasive and cleaning ability, and is relatively soft. When cleaning the paint pen marks on the marking position of the blade disc 200, it can effectively remove stains while avoiding excessive scratching or damage to the ABS plastic base of the blade disc 200, thus ensuring the structural integrity of the blade disc 200. Compared with other possible polishing materials, it better protects the blade disc 200 while satisfying the cleaning effect, making it a reasonable choice for cleaning the blade disc 200.
[0060] Optionally, the scouring pad material can be nylon fiber, polyester fiber, etc. Different materials have different cleaning performance and abrasion resistance. Nylon fiber scouring pads have better abrasion resistance and are suitable for handling rougher stains; polyester fiber scouring pads are relatively soft and cause less damage to the surface of the blade 200. The choice can be made according to the material of the blade 200 and the degree of staining.
[0061] Alternatively, the scouring pad can be bonded to the polishing wheel hub using strong adhesive or mechanical fastening. For adhesive bonding, ensure the adhesive has sufficient bonding strength and temperature resistance to prevent the scouring pad from detaching during polishing. Mechanical fastening can be achieved by using slots or bolts on the hub to secure the scouring pad more firmly and facilitate replacement.
[0062] Alternatively, the polishing wheel hub can be made of aluminum alloy or engineering plastic. Aluminum alloy hubs have high strength and good heat dissipation, making them suitable for long-term high-speed operation; engineering plastic hubs are lower in cost and lighter in weight, making them more suitable for applications where high speed is not required.
[0063] Alternatively, in addition to scouring pad polishing wheels, you can also consider using sandpaper polishing wheels or fiber polishing wheels with different grits. For lighter paint pen marks, use finer grit sandpaper polishing wheels, such as 400-600 grit; for more stubborn stains, use fiber polishing wheels or coarser grit sandpaper polishing wheels, such as 200-400 grit. The polishing wheel diameter should be between 50 and 100 mm, and the thickness between 20 and 40 mm, selected according to the size and shape of the 200-grit area of the blade disc, ensuring complete coverage of the cleaning area with some allowance.
[0064] Optionally, the polishing assembly 30 can also be an ultrasonic polishing assembly, which uses an ultrasonic generator to produce high-frequency vibrations, converting electrical energy into mechanical energy through a transducer to drive a polishing tool (such as an ultrasonic vibrating head) for polishing. This polishing method is suitable for removing stubborn stains or fine oxide layers from the surface of the cutter head 200, and causes less damage to the cutter head 200. Compared with traditional rotary polishing, ultrasonic polishing can achieve better cleaning results without the use of chemical reagents, and is more environmentally friendly.
[0065] Optionally, the polishing assembly 30 can also be a laser polishing assembly, which uses a laser beam to scan and irradiate the surface of the cutter head 200. The high energy of the laser causes the stains to vaporize or ablate instantly, thereby achieving the cleaning purpose. Laser polishing has the advantages of high precision and non-contact operation, and will not cause mechanical damage to the surface of the cutter head 200. It is particularly suitable for cleaning the cutter head 200, which has extremely high requirements for surface roughness and precision.
[0066] Furthermore, the pressure plate assembly 20 includes a connecting seat 21, an optical axis 23, and a pressure plate 25. The connecting seat 21 is connected to the side of the conveyor belt 10. One end of the optical axis 23 is fixedly connected to the connecting seat 21 and extends vertically. The side of the pressure plate 25 is movably connected to the optical axis 23 and is located above the conveyor belt 10. The polishing assembly 30 is installed on the pressure plate 25. The pressure plate 25 moves along the extension direction of the optical axis 23 to approach or move away from the conveyor belt 10.
[0067] Specifically, the connecting seat 21 is connected to the side of the conveyor belt 10, one end of the optical shaft 23 is fixed to the connecting seat 21 and extends vertically, and the side of the pressure plate 25 is movably connected to the optical shaft 23 and is located above the conveyor belt 10. The pressure plate 25 can move along the optical shaft 23 according to its own gravity to achieve the pressing operation of the cutter disc 200, so that the pressure plate 25 continuously presses against different cutter discs 200. This structural design provides stable support and flexible movement for the pressure plate assembly 20, ensuring that the pressure plate 25 can accurately and reliably fix the cutter disc 200, ensuring that the cutter disc 200 will not shake or shift during the cleaning process, which is an important structural foundation for achieving cleaning precision.
[0068] Optionally, the connecting seat 21 and the optical shaft 23 can be connected by an interference fit or a key. If an interference fit is used, the interference amount can be between 0.02 and 0.05 mm, and assembly can be performed by hot fitting or cold pressing. Hot fitting involves heating the optical shaft 23 and inserting it into the hole of the connecting seat 21, achieving a tight fit after cooling. Cold pressing involves using a press to press the optical shaft 23 into the connecting seat 21; the pressure must be carefully controlled to prevent damage to both the connecting seat 21 and the optical shaft 23. If a key connection is used, a flat key or a semi-circular key can be selected. Flat keys are simple to manufacture and widely used; semi-circular keys are suitable for smaller shaft diameters.
[0069] Optionally, the connecting seat 21 can be made of a metal material, such as aluminum alloy, which is lightweight and high-strength. Furthermore, the connecting seat 21 can be L-shaped, with one bottom side fixed to a mounting bracket on the side of the conveyor belt 10 by bolts. The mounting bracket can be welded to the equipment frame to ensure a stable connection. The vertical side is connected to the optical shaft 23, and the connection method can be an interference fit or a keyed connection to ensure that the optical shaft 23 does not undergo relative displacement during operation.
[0070] Optionally, the optical axis 23 is made of stainless steel with a diameter between 15 and 25 mm and its surface is finely ground to ensure that the pressure plate 25 moves smoothly and with high precision on the optical axis 23.
[0071] Optionally, the pressure plate 25 can be made of engineering plastic or aluminum alloy. Engineering plastic has a certain degree of elasticity, which can better protect the surface of the cutter head 200, while aluminum alloy has higher strength. The thickness of the pressure plate 25 is between 10 and 20 mm, and its shape is rectangular. Its area should be able to cover most of the upper surface of the cutter head 200 to ensure effective pressure on the cutter head 200.
[0072] Optionally, the pressure plate assembly 20 can also be a hydraulically driven pressure plate assembly, using a hydraulic cylinder to drive the pressure plate 25 instead of the mechanical structure of the optical shaft 23 and connecting seat 21. The cylinder body of the hydraulic cylinder is fixed to the equipment frame, and the piston rod is connected to the pressure plate 25. Power is provided by the hydraulic system to control the lifting and lowering of the pressure plate 25. Hydraulic drive can provide greater pressure and is suitable for situations requiring stronger fixing force, such as when cleaning larger or harder material cutter heads 200. Compared with mechanical structures, the response speed of hydraulic systems may be slower, but this can be improved by optimizing the hydraulic circuit and selecting appropriate hydraulic components. At the same time, it is necessary to add hydraulic oil filtration and cooling devices to ensure stable system operation and extend the service life of hydraulic components.
[0073] Optionally, the pressure plate assembly 20 can also be an elastic pressure plate assembly, with the pressure plate 25 made of an elastic material such as rubber or spring steel sheet, possessing a certain degree of elastic deformation capability. When the pressure plate 25 contacts the cutter head 200, it relies on elastic deformation to adapt to the slight unevenness of the cutter head 200 surface, providing uniform pressure. This structure can reduce the risk of damage to the cutter head 200 surface, and is especially suitable for cleaning cutter heads 200 with high surface precision requirements. However, the durability of the elastic pressure plate 25 may be relatively poor, requiring regular inspection and replacement to ensure its cleaning effect and stability.
[0074] Furthermore, there are two connecting seats 21 and two optical axes 23. The two connecting seats 21 and the two optical axes 23 are located on both sides of the vertical extension direction of the conveyor belt 10, and the opposite sides of the pressure plate 25 are movably connected to the two optical axes 23.
[0075] In this embodiment, two connecting seats 21 and two optical axes 23 are set, located on opposite sides of the vertical extension direction of the conveyor belt 10. The pressure plate 25 is movably connected to the two optical axes 23 on opposite sides. This symmetrical structural design further enhances the stability and balance of the pressure plate 25's movement, making the pressure plate 25 more evenly stressed when pressing against the cutter disc 200. This ensures the horizontal force balance of the cutter disc 200, preventing it from shifting or tilting, and reducing the risk of deformation or damage due to uneven force. Furthermore, it better adapts to cutter discs 200 of different sizes and weights, improving the cleaning machine's compatibility with various cutter discs 200 and the consistency of cleaning results.
[0076] Furthermore, in terms of equipment installation and commissioning, the symmetrical layout facilitates the determination of the relative positions of each component, reducing installation difficulty. Through precise machining and assembly processes, the positional accuracy of the two connecting seats 21 and the optical axis 23 is ensured to be within ±0.1 mm, enabling the pressure plate 25 to move accurately on the optical axis 23 and press against the cutter head 200, thereby improving the overall performance and reliability of the equipment.
[0077] Furthermore, a plurality of pressing members 251 are protruding on the side surface of the pressure plate 25 facing the conveyor belt 10. The plurality of pressing members 251 are spaced apart on the surface of the pressure plate 25 along the direction perpendicular to the extension of the conveyor belt 10. The ends of the pressing members 251 abut against the surface of the cutter head 200. A clearance space is formed between two adjacent pressing members 251. The clearance space is used for the drill shank 201 of the cutter head 200 to pass through.
[0078] Specifically, the pressure plate 25 has multiple abutment members 251 protruding from its surface facing the conveyor belt 10. These abutment members 251 are spaced apart, with their ends abutting against the surface of the cutter head 200. A clearance space is formed between adjacent abutment members 251 to allow the drill shank 201 of the cutter head 200 to pass through. This design cleverly solves the space clearance problem for the drill shank 201 while ensuring the cutter head 200 is fixed, preventing damage to the drill shank 201 during the pressing process, ensuring the overall structure of the cutter head 200 is not affected, further optimizing the fixing method of the pressure plate assembly 20 for the cutter head 200, and improving the safety and reliability of the cleaning operation.
[0079] Optionally, the pressing element 251 may be made of rubber or silicone, which have good elasticity and wear resistance, and can provide sufficient friction when pressing against the surface of the cutter head 200 without scratching the cutter head 200.
[0080] Optionally, the end of the pressing member 251 can be hemispherical or arc-shaped. This shape can better fit the surface of the cutter head 200, increase the contact area, and improve the pressing effect.
[0081] Optionally, the spacing between adjacent pressing members 251 is determined according to the size and distribution of the drill shank 201 of the cutter head 200, generally between 30 and 50 mm, to ensure that the drill shank 201 can pass smoothly through the clearance space and that other parts of the cutter head 200 can be effectively pressed.
[0082] Optionally, the shape of the clearance space should match the shape of the drill shank 201 of the cutter head 200, and can be circular, elliptical, or rectangular. For a circular drill shank 201, the diameter of the clearance space should be 5-10 mm larger than the diameter of the drill shank 201; for an elliptical or rectangular drill shank 201, the length and width dimensions of the clearance space should be 5-10 mm larger than the length and width dimensions of the drill shank 201, respectively, to ensure that the drill shank 201 is not obstructed when the pressure plate 25 presses against the cutter head 200, and at the same time to avoid affecting the fixing effect of the cutter head 200 due to excessive clearance space.
[0083] Furthermore, the pressing member 251 has an inclined surface at the corner of its side edge along the extension direction of the conveyor belt 10, and the inclined surface is inclined toward the center of the pressing member 251.
[0084] Specifically, an inclined surface is provided at the corner of the side edge of the pressing member 251 along the extension direction of the conveyor belt 10, and the inclined surface is inclined towards the center of the pressing member 251. The inclined surface is mainly designed to guide the cutter disc 200 to better enter the pressing position during the pressing process, reduce the collision and friction between the cutter disc 200 and the pressing member 251, and at the same time allow the pressing member 251 to fit more tightly against the surface of the cutter disc 200, improving the stability of the fixation. When the cutter disc 200 enters under the pressure plate 25 under the push of the conveyor belt 10, the inclined surface allows the cutter disc 200 to slide smoothly between the pressing members 251, avoiding jamming due to angle issues. This design allows the pressing member 251 to transition more smoothly when in contact with the cutter disc 200, reducing stress concentration points, better fitting the surface of the cutter disc 200, further enhancing the fixing effect of the cutter disc 200, and reducing the risk of damage to the surface of the cutter disc 200. This is an optimization and improvement of the structure of the pressing member 251, improving the overall performance of the cleaning machine.
[0085] Optionally, the angle of the inclined surface can be between 30 and 60 degrees, adjusted according to the thickness of the cutter head 200 and the speed at which it enters below the pressure plate 25. If the cutter head 200 is thicker or the entry speed is faster, the angle of the inclined surface can be increased appropriately; conversely, the angle should be decreased. The height of the inclined surface is between 3 and 5 mm, gradually transitioning from the edge of the pressing member 251 towards the center, ensuring that the cutter head 200 can smoothly transition to the pressing position when it contacts the inclined surface.
[0086] Furthermore, the blade cleaning machine 1 also includes a switching valve, which is electrically connected to the conveyor belt 10 and the first drive unit 31. The switching valve simultaneously controls the opening or closing of the conveyor belt 10 and the first drive unit 31.
[0087] In this embodiment, a switching valve is introduced as a control component, electrically connected to the conveyor belt 10 and the first drive unit 31, capable of simultaneously controlling their opening and closing. This design achieves synchronous and coordinated control of the operation of key components of the cleaning machine. Operators only need to operate the switching valve to easily start or stop the conveying and polishing operations of the blade disc 200, simplifying the operation process, improving operational convenience and ease of use of the equipment, and reducing operational errors that may occur due to controlling different components separately. Furthermore, it can simultaneously control the closing of the conveyor belt 10 and the first drive unit 31, that is, simultaneously shutting off the rotation of the conveyor belt 10 and the polishing component 33, preventing the polishing component 33 from continuously polishing in one position and thus damaging the overall plastic of the blade disc 200, improving safety and intelligence.
[0088] Optionally, the switching valve can be either an electromagnetic switching valve or a pneumatic switching valve. Electromagnetic switching valves offer high control precision and fast response, controlling the opening and closing of the valve core via electrical signals; pneumatic switching valves, on the other hand, have the advantages of simple structure and high reliability, using compressed air to drive the valve core. The choice depends on the equipment's working environment and control requirements; for example, in applications requiring explosion-proof protection, a pneumatic switching valve can be selected.
[0089] Control Logic: The switching valve is connected to the control circuits of the conveyor belt 10 motor and the polishing component 30 motor. When the switching valve opens, it simultaneously sends start signals to both the conveyor belt 10 motor and the polishing component 30 motor, causing them to start working at the same time. When the switching valve closes, it simultaneously cuts off the power to both motors, stopping the equipment operation. Overload protection and short-circuit protection functions can be set in the control circuit to ensure the equipment can safely stop operating under abnormal conditions, protecting the equipment and the safety of operators.
[0090] Furthermore, the blade cleaning machine 1 also includes a sensor 50 and an electronic control device. The sensor 50 is located at the end of the conveyor belt 10 and is electrically connected to the electronic control device. The sensor 50 is used to detect whether the blade 200 is removed from the conveyor belt 10.
[0091] In this embodiment, sensor 50 is located at the end of conveyor belt 10 and electrically connected to the electronic control device to detect whether the cutter head 200 has been removed from conveyor belt 10. Through this monitoring mechanism, when the cutter head 200 is not removed in time, the electronic control device can take corresponding measures, such as pausing equipment operation or issuing an alarm, to prevent subsequent cutter heads 200 from colliding with the unremoved cutter head 200 or other unexpected situations. This ensures the safety and continuity of equipment operation and effectively avoids equipment failures, product damage, and production accidents that may be caused by human negligence or improper operation.
[0092] Optionally, sensor 50 can be an infrared sensor or a proximity sensor. An infrared sensor detects the presence of the cutter head 200 by emitting and receiving infrared light, featuring high detection accuracy and rapid response; the proximity sensor 50 uses electromagnetic induction to detect the proximity of the metal cutter head 200, offering high reliability. Sensor 50 is mounted on a bracket at the end of the conveyor belt 10, and its position is adjusted to accurately detect whether the cutter head 200 has been removed at the correct height and angle.
[0093] Optionally, the electrical control device can employ a programmable logic controller (PLC) or a microcontroller control system. PLCs offer advantages such as high reliability, convenient programming, and strong expandability, enabling easy acquisition and processing of signals from sensor 50 and control of the equipment's operating status according to preset logic. Microcontroller control systems, on the other hand, are less expensive and more suitable for equipment with relatively simple functional requirements. The electrical control device determines whether the cutter head 200 has been removed based on the signal from sensor 50. If the cutter head 200 is not detected to have been removed within a specified time (e.g., 10-30 seconds), an alarm signal is issued, such as an audible and visual alarm, and the equipment can be paused to prevent subsequent cutter heads 200 from entering and causing blockages or collisions.

It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention.
