Description

Technical Field

[0001] The invention relates to the technical field of blade disc cleaning, and in particular to a blade disc cleaning machine. Background Art

[0002] In the PCB industry, CNC drilling machines are key production equipment, and the cutter head is an important component. The cutter head is generally made of ABS plastic, which has certain strength and durability. It is mainly used to fix and support the drill bit, ensuring the stability and accuracy of the drill bit during work, thereby ensuring the quality and accuracy of PCB drilling.

[0003] With the demand for the new drill bit think tank system, a large number of existing old cutter discs need to be coded. The coding position is in the 54mm×10mm area near the handle of the cutter disc edge. The original life control was done manually with paint pens, which made the position to be coded dirty.

[0004] Therefore, it is necessary to clean the coded position to remove the original mark. One of the existing cleaning methods is to use solvents (such as oil water) to manually wipe off the dirt. However, this solvent is not only toxic and harmful to people's health, but also extremely flammable and poses a safety hazard. In addition, the cleaning method of using solvents to wipe off has other disadvantages, such as the difficulty in controlling the amount of solvent used. Too much solvent will dissolve the base plastic of the blade disc and affect the structure of the blade disc. Too little solvent will not be able to quickly remove the paint pen marks, resulting in low cleaning efficiency. If the solvent cleaning method is automated according to this idea, it will still face problems such as environmental exhaust ventilation, explosion-proof electrical equipment, and sewage treatment after improvement. The cost is high and the implementation is difficult. Therefore, a cleaning method is needed to solve the problems of high cleaning difficulty, high degree of danger, and high degree of cleaning pollution in the existing cleaning method.

[0011] Furthermore, the number of the connecting seats and the number of the optical axes are both two, the two connecting seats and the two optical axes are respectively located on both sides of the vertical extension direction of the conveyor belt, and the opposite side edges of the pressure plate are respectively movably connected to the two optical axes.

[0012] Furthermore, a plurality of pressure members are protruding from a surface of one side of the pressure plate facing the conveyor belt, and the plurality of pressure members are located on the surface of the pressure plate and are spaced apart along a direction perpendicular to the extension direction of the conveyor belt. Ends of the pressure members are abutted against the surface of the cutter disc, and an escape space is formed between two adjacent pressure members, and the escape space is used for the drill shank of the cutter disc to pass through.

[0013] Furthermore, an inclined surface is provided at a side edge corner of the pressing member along the extending direction of the conveyor belt, and the inclined surface is inclined toward the center of the pressing member.

[0024] like Figures 1 to 6 As shown, the present application provides a cutter disc cleaning machine 1, which is used for cleaning a cutter disc 200. The cutter disc cleaning machine 1 includes: Conveyor belt 10, conveyor belt 10 is used for conveying the cutter disc 200; A pressure plate assembly 20, the pressure plate assembly 20 is movably connected to the top of the conveyor belt 10, and the pressure plate assembly 20 can move in a direction close to or away from the conveyor belt 10 to press against or disengage from the cutter disc 200; The polishing assembly 30 is mounted on the pressure plate 25. The polishing assembly 30 includes a first driving member 31 and a polishing member 33. The polishing member 33 is located above the conveyor belt 10. 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 blade disc 200. The movement of the pressure plate assembly 20 drives the movement of the polishing assembly 30. The dust suction assembly 40 is located above the polishing piece 33 , and the dust suction port of the dust suction assembly 40 is arranged toward the polishing piece 33 .

[0025] The cutter disc cleaning machine 1 includes a conveyor belt 10, a pressure plate assembly 20, a polishing assembly 30 and a dust collection assembly 40. The conveyor belt 10 is responsible for conveying the cutter disc 200 and is a basic component for realizing an automated cleaning process; the pressure plate assembly 20 can move and press against or detach from the cutter disc 200 to ensure that the position of the cutter disc 200 is stable during cleaning and ensure the accuracy of cleaning; the polishing assembly 30 is installed on the pressure plate 25, and its first driving member 31 drives the polishing member 33 to rotate to realize the cleaning function, and cleans the coding position of the cutter disc 200 to avoid damage to other parts of the cutter disc 200; the dust collection assembly 40 is located above the polishing member 33, and the dust collection port faces the polishing member 33, which can promptly suck away the debris generated by cleaning to prevent pollution and equipment failure. These components work together to form the core architecture of the cutter disc cleaning machine 1.

[0026] In actual operation, first place the cutter disc 200 to be cleaned at the starting end of the conveyor belt 10, start the conveyor belt 10, and the conveyor belt 10 starts to run to transport the cutter disc 200 to the cleaning area. At this time, the pressure plate assembly 20 moves, causing the pressure plate 25 to drop and press against the cutter disc 200 to fix the position of the cutter disc 200. Next, the first drive member 31 drives the polishing member 33 to rotate at high speed to clean the coding area of ​​the cutter disc 200, and the dust collection assembly 40 works synchronously to absorb the debris generated by cleaning. After cleaning is completed, the pressure plate assembly 20 releases the cutter disc 200, and the conveyor belt 10 sends the cleaned cutter disc 200 out of the cleaning area. The cutter disc 200 can be taken out of the conveyor belt 10 manually or by a feeding mechanism.

[0027] Optionally, a rubber conveyor belt 10 can be used, which has good flexibility and wear resistance and can adapt to long-term conveying work of the cutter disc 200. In addition, the conveyor belt 10 can be driven by a motor, and the motor power can be selected according to the load capacity and running speed requirements of the conveyor belt 10. The motor is connected to the driving shaft of the conveyor belt 10 through a speed reduction device to achieve stable power transmission and ensure that the conveyor belt 10 runs at a suitable speed.

[0028] Optionally, the pressure plate assembly 20 may be a combination of a spring and a pressure plate 25 , or a combination of the optical axis 23 and the pressure plate 25 , or a combination of a slide rail slider and the pressure plate 25 .

[0029] Optionally, the first driving member 31 can be a DC motor or an AC variable frequency motor. The DC motor is easy to adjust the speed and can meet different cleaning requirements; the AC variable frequency motor has the advantages of energy saving and stable operation. The motor is connected to the polishing member 33 through a belt drive or a coupling to ensure high efficiency of power transmission.

[0030] Optionally, the dust collection assembly 40 includes a dust collector and a dust collection duct. The dust collector can be an industrial-grade cyclone vacuum cleaner or a bag vacuum cleaner. The cyclone vacuum cleaner has a good separation effect on larger particles of debris and can quickly suck most of the debris into the dust collection bucket; the bag vacuum cleaner has a better filtering effect on fine dust and can ensure that the exhausted air is clean and pollution-free. The dust collection duct is made of plastic or metal, such as PVC plastic or galvanized steel pipe. The diameter of the dust collection duct is between 30 and 50 mm, and the interior must be smooth to reduce airflow resistance and ensure that the debris can be smoothly sucked into the vacuum cleaner. The shape of the dust suction port can be circular or rectangular, and it needs to be designed according to the size and shape of the polishing part 33 to ensure that the dust suction port can cover the polishing area and effectively suck away the generated debris.

[0031] Optionally, the dust collection component 40 can also be an electrostatic dust collection component 40, which uses the principle of electrostatic adsorption to set an electrostatic field in the dust collection pipe, so that the debris is charged when passing through and adsorbed on the electrode plate. This dust collection method has a better collection effect on fine dust and light debris, and can effectively improve the dust collection efficiency and the quality of air purification.

[0032] Optionally, the dust suction assembly 40 can also be a water curtain dust suction assembly 40. By setting a water curtain near the dust suction port, when the debris is sucked in, it is first washed by the water curtain, the dust and debris are brought into the water, and then the sewage is discharged and processed through the water circulation system. The water curtain dust suction can effectively capture and collect a large amount of dust and debris, and can also play a role in cooling and fire prevention.

[0033] Furthermore, the conveyor belt 10 is provided with a plurality of baffles 11, which are connected to the conveyor belt 10 along an extension direction perpendicular to the conveyor belt 10, and the plurality of baffles 11 are arranged at intervals, and a accommodating space is formed between two adjacent baffles 11, and a accommodating space is used to place a cutter disc 200.

[0034] Specifically, the conveyor belt 10 is provided with a plurality of baffles 11, and the baffles 11 are connected in a direction perpendicular to the extending direction of the conveyor belt 10, and are arranged at intervals to form a receiving space for placing the cutter disc 200. This structural design enables the cutter disc 200 to be orderly separated and fixed during the conveying process, preventing the cutter disc 200 from displacement or collision during the conveying process, further ensuring the stability and accuracy of the conveying of the cutter disc 200, and compared with the conveyor belt 10 without baffles 11, it can better adapt to the automated process of cleaning the cutter disc 200, thereby improving the reliability and working efficiency of the cleaning machine.

[0035] Optionally, the baffle 11 can be made of plastic or rubber. The plastic baffle 11, such as ABS plastic, has certain strength and toughness and is not easy to deform; the rubber baffle 11 has better buffering performance and can prevent the blade 200 from being damaged when it collides with the baffle 11. The thickness of the baffle 11 is between 3 and 8 mm, and the height is determined according to the thickness of the blade 200, which is generally 10 to 20 mm higher than the thickness of the blade 200, to ensure that the blade 200 is stably placed in the accommodation space and will not fall out.

[0036] Optionally, the baffle 11 is fixed to the conveyor belt 10 by welding, riveting or bolting. The welding method is firm but not easy to disassemble; the riveting method is relatively simple, but the connection strength is slightly weaker; the bolt connection is easy to install and maintain, and can be selected according to actual needs. The distance between adjacent baffles 11 is determined according to the diameter of the cutter disc 200, and is generally 5 to 10 mm larger than the diameter of the cutter disc 200, to ensure that the cutter disc 200 can be smoothly placed in the accommodation space and will not be too loose to cause shaking.

[0037] Furthermore, the conveyor belt 10 is a circulating baffle conveyor belt.

[0038] In this embodiment, the conveyor belt 10 has a circulating structure so that the conveyor belt 10 can 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 and reduces equipment downtime. It is a further optimization and improvement of the function of the conveyor belt 10 and enhances the practicability of the cleaning machine in batch cutter disc 200 cleaning operations.

[0039] Furthermore, the circulating baffle conveyor belt includes a driving wheel and a tensioning device. The driving wheel is made of metal material, such as carbon steel or stainless steel, and the surface is quenched to improve hardness and wear resistance. The driving wheel is installed on the equipment frame through a bearing. The bearing uses a deep groove ball bearing, which can withstand certain radial and axial loads to ensure that the driving wheel rotates flexibly. The tensioning device can adopt a screw-type tensioning device or a weight-type tensioning device. The screw-type tensioning device adjusts the tension of the conveyor belt 10 by rotating the screw, which is easy to operate and has high adjustment accuracy; the weight-type tensioning device uses the gravity of the weight to automatically maintain the tension of the conveyor belt 10, and has high reliability. The tensioning device is installed on the driven wheel side of the conveyor belt 10. According to the length and operation of the conveyor belt 10, the tensioning force is reasonably adjusted to ensure that the conveyor belt 10 does not become loose or deviate during the circulation operation.

[0040] Optionally, the conveyor belt 10 can also be a chain conveyor belt, using a metal chain as a transmission component, and a special tray is installed on the chain to place the cutter disc 200. The tray can be connected to the chain links by welding or bolts to ensure stability. The advantage of this structure is that it has a strong load-bearing capacity and is suitable for heavier cutter discs 200 or working in harsh environments, such as where there is a lot of dust and debris that may affect the normal operation of the rubber conveyor belt 10. Compared with the belt conveyor 10, the chain conveyor belt has a longer service life, but it may generate louder noise and needs to be equipped with appropriate noise reduction measures, such as installing a soundproof cover or using a special chain lubrication method to reduce noise.

[0041] Optionally, the conveyor belt 10 can also be a magnetic conveyor belt, with magnetic materials embedded on the surface or inside of the conveyor belt 10, and the cutter disc 200 is made of a material that can be attracted by magnetism or has a magnetic attachment installed at the bottom. During the conveying process, the cutter disc 200 is adsorbed on the conveyor belt 10 by magnetic force, and no additional baffle 11 is required to fix it. The advantage of this design is that it can simplify the structure, reduce the number of components, and reduce equipment costs and maintenance difficulties. However, it has certain requirements on the material of the cutter disc 200, and the magnetic strength needs to be precisely controlled to ensure that the cutter disc 200 can be stably adsorbed and easily removed from the conveyor belt 10.

[0042] Furthermore, the polishing member 33 is a scouring pad polishing wheel.

[0043] In this embodiment, the scouring pad material has certain grinding and cleaning capabilities and is relatively soft. When cleaning the paint pen marks at the coding position of the blade disc 200, it can not only effectively remove stains, but also avoid excessive scratches or damage to the ABS plastic base of the blade disc 200, thereby ensuring the structural integrity of the blade disc 200. Compared with other possible polishing materials, it better protects the blade disc 200 while meeting the cleaning effect, and is a reasonable choice suitable for the cleaning scenario of the blade disc 200.

[0044] Optionally, the material of the scouring pad: nylon fiber, polyester fiber and other materials can be used. Different materials of scouring pads have different cleaning performance and wear resistance. Nylon fiber scouring pads have good wear resistance and are suitable for handling relatively rough stains; polyester fiber scouring pads are relatively soft and cause less damage to the surface of the blade disc 200. You can choose according to the material of the blade disc 200 and the stain situation.

[0045] Optionally, the scouring pad and the polishing wheel hub can be bonded by strong glue or mechanical fixing. In the case of glue bonding, it is necessary to ensure that the glue has sufficient bonding strength and temperature resistance to prevent the scouring pad from falling off during the polishing process; the mechanical fixing method can be to set a slot or bolt on the hub to make the scouring pad more firmly fixed and easy to replace.

[0046] Optionally, the polishing wheel hub can be made of aluminum alloy or engineering plastic. Aluminum alloy hubs have high strength and good heat dissipation, and are suitable for long-term high-speed operation; engineering plastic hubs have low cost and light weight, and are more suitable for occasions where the speed requirements are not high.

[0047] Optionally, in addition to the scouring pad polishing wheel, you can also consider using sandpaper polishing wheels or fiber polishing wheels of different grits. For lighter paint pen marks, you can use a finer grit sandpaper polishing wheel, such as 400~600 mesh; for more stubborn stains, use a fiber polishing wheel or a coarser grit sandpaper polishing wheel, such as 200~400 mesh. The polishing wheel has a diameter of 50~100 mm and a thickness of 20~40 mm. It is selected according to the size and shape of the coding area of ​​the knife disc 200 to ensure that it can fully cover the cleaning area with a certain margin.

[0048] Optionally, the polishing assembly 30 can also be an ultrasonic polishing assembly, which uses an ultrasonic generator to generate high-frequency vibration, converts electrical energy into mechanical energy through a transducer, and drives a polishing tool (such as an ultrasonic vibration head) for polishing. This polishing method is suitable for removing stubborn stains or fine oxide layers on 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 effects without using chemical reagents, and is more environmentally friendly.

[0049] Optionally, the polishing assembly 30 may also be a laser polishing assembly, which uses a laser beam to scan and irradiate the surface of the cutter head 200, and uses the high energy of the laser to instantly vaporize or ablate the stains, thereby achieving the purpose of cleaning. Laser polishing has the advantages of high precision and non-contact, and will not cause mechanical damage to the surface of the cutter head 200, and is particularly suitable for cleaning the cutter head 200 that has extremely high requirements for surface roughness and precision.

[0050] 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 in the vertical direction. 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, and the pressure plate 25 moves along the extension direction of the optical axis 23 to approach or move away from the conveyor belt 10.

[0051] Specifically, the connection seat 21 is connected to the side of the conveyor belt 10, one end of the optical axis 23 is fixed to the connection 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, and the pressure plate 25 can move along the optical axis 23 according to its own gravity to achieve the pressing operation on the cutter disc 200, so that the pressure plate 25 continuously presses 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 move during the cleaning process, and is an important structural basis for achieving cleaning accuracy.

[0052] Optionally, the connection seat 21 and the optical axis 23 can be connected by interference fit or key connection. If interference fit connection is adopted, the interference amount can be between 0.02 and 0.05 mm, and hot fitting or cold pressing can be adopted during assembly. Hot fitting is to heat the optical axis 23 and insert it into the hole of the connection seat 21, and achieve a tight fit after cooling; cold pressing is to use a press to press the optical axis 23 into the connection seat 21, and the pressure needs to be controlled to prevent damage to the connection seat 21 and the optical axis 23. If a key connection is adopted, the key can be a flat key or a semicircular key. Flat keys are simple to manufacture and widely used; semicircular keys are suitable for situations with smaller shaft diameters.

[0053] Optionally, the connection seat 21 can be made of metal materials, such as aluminum alloy, which has the characteristics of light weight and high strength. Further, the connection seat 21 can be L-shaped, with one side of the bottom fixed to the mounting bracket on the side of the conveyor belt 10 by bolts, and the mounting bracket can be welded to the equipment frame to ensure the stability of the connection; one side of the vertical part is connected to the optical axis 23, and the connection method can be interference fit or key connection to ensure that the optical axis 23 will not be relatively displaced during operation.

[0054] Optionally, the optical axis 23 is made of stainless steel with a diameter between 15 and 25 mm, and the surface is finely ground to ensure that the pressing plate 25 moves smoothly and with high precision on the optical axis 23 .

[0055] Optionally, the pressure plate 25 can be made of engineering plastic or aluminum alloy. The engineering plastic has a certain elasticity and can better protect the surface of the cutter disc 200, while the aluminum alloy has higher strength. The thickness of the pressure plate 25 is between 10 and 20 mm, and the shape is rectangular. Its area should be able to cover most of the upper surface of the cutter disc 200 to ensure effective pressure on the cutter disc 200.

[0056] Optionally, the pressure plate assembly 20 can also be a hydraulically driven pressure plate assembly, using a hydraulic cylinder to replace the mechanical structure of the optical axis 23 and the connecting seat 21 to drive the pressure plate 25. 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 where stronger fixing force is required, such as when cleaning a larger or harder cutter disc 200. Compared with the mechanical structure, the response speed of the hydraulic system may be slower, but it can be improved by optimizing the hydraulic circuit and selecting suitable hydraulic components. At the same time, it is necessary to add a filter and cooling device for the hydraulic oil to ensure the stable operation of the system and extend the service life of the hydraulic components.

[0057] Optionally, the pressure plate assembly 20 can also be an elastic pressure plate assembly, and the pressure plate 25 is made of an elastic material such as rubber or spring steel sheet, and has a certain elastic deformation ability. When the pressure plate 25 contacts the cutter disc 200, it relies on elastic deformation to adapt to the slight unevenness of the surface of the cutter disc 200 and provide uniform pressure. This structure can reduce the risk of damage to the surface of the cutter disc 200, and is particularly suitable for cleaning cutter discs 200 with high surface accuracy requirements. However, the durability of the elastic pressure plate 25 may be relatively poor, and it needs to be regularly inspected and replaced to ensure its cleaning effect and stability.

[0058] Furthermore, there are two connecting seats 21 and two optical axes 23 , which are respectively located on both sides of the vertical extension direction of the conveyor belt 10 , and the opposite side edges of the pressure plate 25 are movably connected to the two optical axes 23 .

[0059] In this embodiment, the number of the connecting seat 21 and the optical axis 23 is set to two, and they are respectively located on both sides of the vertical extension direction of the conveyor belt 10, and the two opposite sides of the pressure plate 25 are respectively movably connected to the two optical axes 23. This symmetrical structural design further enhances the stability and balance of the movement of the pressure plate 25, so that the pressure plate 25 is subjected to more uniform force when pressing against the cutter disc 200, ensuring the force balance of the cutter disc 200 in the horizontal direction, avoiding the cutter disc 200 from being offset or tilted, and reducing the risk of deformation or damage of the cutter disc 200 due to uneven force. It can also better adapt to cutter discs 200 of different sizes and weights, improving the compatibility of the cleaning machine with a variety of cutter discs 200 and the consistency of the cleaning effect.

[0060] Furthermore, in terms of equipment installation and commissioning, the symmetrical layout facilitates the determination of the relative position relationship of each component, reducing the difficulty of installation. Through precise machining and assembly processes, the position accuracy of the two connecting seats 21 and the optical axis 23 is ensured to be within ±0.1 mm, so that the pressing plate 25 can accurately move on the optical axis 23 and press the cutter disc 200, thereby improving the overall performance and reliability of the equipment.

[0061] Furthermore, a plurality of pressure members 251 are protruding from the surface of the pressure plate 25 on one side facing the conveyor belt 10. The plurality of pressure members 251 are located on the surface of the pressure plate 25 and are spaced apart along a direction perpendicular to the extension direction of the conveyor belt 10. Ends of the pressure members 251 are pressed against the surface of the cutter disc 200. An escape space is formed between two adjacent pressure members 251. The escape space is used for the drill shank 201 of the cutter disc 200 to pass through.

[0062] Specifically, a plurality of pressing members 251 are convexly provided on the surface of the pressure plate 25 facing the conveyor belt 10. These pressing members 251 are arranged at intervals, and their ends press against the surface of the cutter disc 200, and an escape space is formed between adjacent pressing members 251 for the drill shank 201 of the cutter disc 200 to pass through. This design cleverly solves the problem of space escape of the drill shank 201 of the cutter disc 200 while ensuring the fixation of the cutter disc 200, preventing damage to the drill shank 201 during the pressing process, ensuring that the overall structure of the cutter disc 200 is not affected, further optimizing the fixing method of the pressure plate assembly 20 to the cutter disc 200, and improving the safety and reliability of the cleaning operation.

[0063] Optionally, the pressing member 251 may be made of rubber or silicone material, which has good elasticity and wear resistance and can provide sufficient friction when pressing against the surface of the cutter disc 200 without scratching the cutter disc 200 .

[0064] Optionally, the end of the pressing member 251 may be hemispherical or arc-shaped, and this shape can better fit the surface of the cutter disc 200, increase the contact area, and improve the pressing effect.

[0065] 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, and is generally between 30 and 50 mm, to ensure that the drill shank 201 can smoothly pass through the avoidance space and other parts of the cutter head 200 can be effectively pressed.

[0066] Optionally, the shape of the avoidance space should match the shape of the drill handle 201 of the cutter head 200, and can be circular, oval or rectangular. For a circular drill handle 201, the diameter of the avoidance space should be 5 to 10 mm larger than the diameter of the drill handle 201; for an oval or rectangular drill handle 201, the length and width of the avoidance space should be 5 to 10 mm larger than the length and width of the drill handle 201, respectively, to ensure that the drill handle 201 will not be obstructed when the pressure plate 25 presses against the cutter head 200, and to avoid affecting the fixing effect of the cutter head 200 due to the excessive size of the avoidance space.

[0067] Furthermore, an inclined surface is provided at a corner of the side edge of the pressing member 251 along the extending direction of the conveyor belt 10 , and the inclined surface is inclined toward the center of the pressing member 251 .

[0068] Specifically, an inclined surface is provided at the corner of the side edge of the pressing member 251 along the extending direction of the conveyor belt 10, and the inclined surface is inclined toward the center of the pressing member 251. The inclined surface is provided mainly to guide the cutter disc 200 to enter the pressing position better during the pressing process, reduce the collision and friction between the cutter disc 200 and the pressing member 251, and enable the pressing member 251 to fit the surface of the cutter disc 200 more closely, thereby 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 enables the cutter disc 200 to slide smoothly between the pressing members 251, thereby avoiding jamming due to angle problems. This design enables the pressing member 251 to transition more smoothly when in contact with the cutter disc 200, reduces stress concentration points, better fits the surface of the cutter disc 200, further enhances the fixing effect of the cutter disc 200, and reduces the risk of damage to the surface of the cutter disc 200. It is an optimization and improvement of the structure of the pressing member 251, thereby improving the overall performance of the cleaning machine.

[0069] Optionally, the angle of the inclined surface can be between 30 and 60 degrees, and can be adjusted according to the thickness of the blade disc 200 and the speed of entering under the pressure plate 25. If the blade disc 200 is thicker or the speed of entering is faster, the angle of the inclined surface can be appropriately increased; otherwise, the angle can be reduced. The height of the inclined surface is between 3 and 5 mm, and gradually transitions from the edge of the pressing member 251 to the center, ensuring that the blade disc 200 can smoothly transition to the pressing position when contacting the inclined surface.

[0070] Furthermore, the blade cleaning machine 1 also includes a switch valve, which is electrically connected to the conveyor belt 10 and the first driving member 31, and the switch valve controls the opening or closing of the conveyor belt 10 and the first driving member 31 at the same time.

[0071] In this embodiment, a control component, a switch valve, is introduced, which is electrically connected to the conveyor belt 10 and the first drive member 31, and can control the opening or closing of the two at the same time. This design realizes the synchronous and coordinated control of the operation of the key components of the cleaning machine. The operator only needs to operate the switch valve to conveniently start or stop the conveying and polishing operations of the cutter disc 200, which simplifies the operation process, improves the convenience of operation and the ease of use of the equipment, and reduces the operational errors that may be caused by controlling different components separately. And it can control the closing of the conveyor belt 10 and the first drive member 31 at the same time, that is, the conveyor belt 10 and the polishing member 33 are turned off at the same time, so as to avoid the polishing member 33 from continuously polishing in one position and thus damaging the collective plastic of the cutter disc 200, thereby improving safety and intelligence.

[0072] Optionally, the switch valve can be an electromagnetic switch valve or a pneumatic switch valve. The electromagnetic switch valve has high control accuracy and fast response speed, and controls the opening and closing of the valve core through electrical signals; the pneumatic switch valve has the advantages of simple structure and high reliability, and uses compressed air to drive the valve core to move. The selection is based on the working environment and control requirements of the equipment. For example, in occasions with explosion-proof requirements, a pneumatic switch valve can be selected.

[0073] Control logic: The switch valve is connected to the control circuit of the conveyor belt 10 motor and the polishing assembly 30 motor. When the switch valve is opened, a start signal is sent to the conveyor belt 10 motor and the polishing assembly 30 motor at the same time, so that both start working at the same time; when the switch valve is closed, the power supply of the two motors is cut off at the same time, and the equipment stops running. Overload protection, short circuit protection and other functions can be set in the control circuit to ensure that the equipment can stop running safely under abnormal conditions, protecting the safety of the equipment and operators.

[0074] Furthermore, the cutter disc cleaning machine 1 also includes a sensor 50 and an electronic control device. The sensor 50 is arranged 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 cutter disc 200 is taken out from the conveyor belt 10.

[0075] In this embodiment, the sensor 50 is arranged at the end of the conveyor belt 10 and is electrically connected to the electric control device to detect whether the cutter disc 200 is removed from the conveyor belt 10. Through this monitoring mechanism, when the cutter disc 200 is not removed in time, the electric control device can take corresponding measures, such as suspending the operation of the equipment or issuing an alarm to prevent the subsequent cutter disc 200 from colliding with the cutter disc 200 that has not been removed or other accidents, thereby ensuring the safety and continuity of the operation of the equipment and effectively avoiding equipment failures, product damage and production accidents that may be caused by human negligence or improper operation.

[0076] Optionally, the sensor 50 may be an infrared sensor or a proximity sensor. The infrared sensor detects the presence of the cutter disc 200 by emitting and receiving infrared rays, and has the characteristics of high detection accuracy and sensitive response; the proximity sensor 50 detects the proximity of the metal cutter disc 200 by using the principle of electromagnetic induction, and has high reliability. The sensor 50 is installed on the bracket at the end of the conveyor belt 10, and the position should be adjusted to a height and angle that can accurately detect whether the cutter disc 200 has been taken away.

[0077] Optionally, the electric control device may adopt a programmable logic controller (PLC) or a single-chip microcomputer control system. PLC has the advantages of high reliability, convenient programming, strong scalability, etc. It can easily realize the acquisition and processing of the sensor 50 signal and control the operating state of the equipment according to the preset logic; the single-chip microcomputer control system is relatively low in cost and is more suitable for equipment with relatively simple functional requirements. The electric control device determines whether the cutter disc 200 has been removed based on the signal of the sensor 50. If the cutter disc 200 is not detected to be removed within the specified time (such as 10 to 30 seconds), an alarm signal, such as an audible and visual alarm, is issued, and the equipment can be controlled to suspend operation to prevent the subsequent cutter disc 200 from entering and causing a blockage or collision accident.

It should be pointed out that, for ordinary technicians in this field, the above technical features can be freely combined without departing from the concept of the present invention, and several deformations and improvements can be made, which all belong to the protection scope of the present invention.
