[0028] Please refer to Figures 1-4As shown, the air conditioner filter paper core drilling device provided by the embodiment of the application comprises a workbench 1, a drilling device 2 and a filter paper tray 3 are arranged on the workbench 1, and the filter paper tray 3 is arranged below the drilling device 2; the drilling device 2 comprises a controller 21, a starting switch 22, a cutter die mechanism 23, an extension mechanism 24 and a rotating mechanism 25, the starting switch 22 is connected to the controller 21, the controller 21 is connected to the cutter die mechanism 23, the rotating mechanism 25 is connected to the extension mechanism 24, the extension mechanism 24 is connected to the cutter die mechanism 23, and the rotating mechanism 25 is used to drive the extension mechanism 24 to move downward or upward when rotating, so that the cutter die mechanism 23 moves in the direction away from or close to the filter paper tray 3 in the height direction; the filter paper tray 3 comprises a fixed bottom support 31 and a movable tray 32, the size of the movable tray 32 is smaller than the size of the fixed bottom support 31, the movable tray 32 is embedded in the fixed bottom support 31, and the movable tray 32 can move in the fixed bottom support 31.

[0029] The drilling device provided by the embodiment comprises the workbench 1, the drilling device 2 and the filter paper tray 3 arranged on the workbench 1, the filter paper tray 3 is used to support the air conditioner filter paper and provides the air conditioner filter paper with the functions of auxiliary fixing and positioning during drilling, so as to avoid the air conditioner filter paper from moving randomly, and the drilling device 2 is used to drill the air conditioner filter paper supported in the filter paper tray 3; wherein the filter paper tray 3 comprises the fixed bottom support 31 and the movable tray 32, the size of the movable tray 32 is smaller than the size of the fixed bottom support 31, the movable tray 32 is embedded in the fixed bottom support 31, and the movable tray 32 can move in the fixed bottom support 31, that is, the filter paper tray 3 is composed of two components, the installation position of the fixed bottom support 31 is fixed and does not change, and the fixed bottom support 31 plays a supporting role, the movable tray 32 is placed on the fixed bottom support 31 and can move in the fixed bottom support 31, therefore, after the drilling device 2 drills the air conditioner filter paper on the movable tray 32, the movable tray 32 only needs to be moved left and right on the fixed bottom support 31, and then the drilling device 2 can be operated again to drill another position of the air conditioner filter paper, without the need of taking up and placing the air conditioner filter paper again, which reduces manual operation and ensures more accurate drilling position.

[0030] The workbench 1 serves as the foundation of the entire device, providing a stable support environment to ensure stability and accuracy during drilling operations. The drilling equipment 2 and filter paper tray 3 are arranged reasonably on the workbench 1, making the operation smooth and efficient. As the "brain" of the entire drilling equipment 2, the controller 21 is responsible for receiving instructions, processing data, and controlling the coordinated work of other components. The user sends instructions to the controller 21 by starting the switch 22, starting or stopping the drilling operation. The cutter mechanism 23 is the component that directly performs the drilling operation, and its shape and size are designed according to the required hole diameter. The telescopic mechanism 24 connects the cutter mechanism 23 and the rotating mechanism 25, responsible for adjusting the position of the cutter mechanism 23 in the height direction, so that it can accurately contact the filter paper. The rotating mechanism 25 drives the telescopic mechanism 24 and the cutter mechanism 23 to move downward or upward through its rotary motion, thereby realizing the drilling operation on the filter paper. Not only does it improve the accuracy of drilling, but it also makes the operation more flexible and efficient. As the support part of the filter paper tray 3, the fixed base 31 provides a stable placement environment to ensure that the filter paper does not move or deform during drilling. The movable tray 32 is smaller than the fixed base 31 and can be embedded in the fixed base 31 and freely moved, so that the user can easily adjust the position of the filter paper to adapt to different drilling needs. At the same time, the movable tray 32 can be easily removed and replaced, improving work efficiency.

[0031] The above-mentioned workbench 1 includes a support frame 11 and a connecting rod 12, the connecting rod 12 is installed on the support frame 11, and the drilling equipment 2 and the filter paper tray 3 are arranged on the connecting rod 12. The support frame 11 serves as the foundation of the entire workbench 1, providing sufficient stability and load-bearing capacity. It ensures that the drilling equipment 2 and the filter paper tray 3 will not tip over or deform during installation and use due to weight or operating force. In addition, the support frame 11 can also be designed to be adjustable in height to adapt to different height requirements. The connecting rod 12 connects the drilling equipment 2 and the filter paper tray 3 together to form a whole working unit, reducing the complexity of operating each component separately. The drilling equipment 2 is fixed on the support frame 11 through the connecting rod 12, ensuring its stability and accuracy during operation. The filter paper tray 3 is also fixed on the support frame 11 through the connecting rod 12, used to place the air conditioner filter paper to be processed. The design of the movable tray 32 should facilitate the quick placement and removal of the filter paper, while ensuring the stability and positioning accuracy of the filter paper during drilling.

[0032] As a preferred embodiment, the rotating mechanism 25 comprises a rotating disc 251, a rotating shaft (not shown) and a transmission assembly (not shown), the rotating disc 251 is connected to one end of the rotating shaft, the other end of the rotating shaft is connected to the transmission assembly, and the transmission assembly is connected to the die mechanism 23. The rotating disc 251 is the starting part of the rotating mechanism 25, which can be manually driven or driven by a motor, and mainly functions to transmit the rotary motion to the rotating shaft. The rotating shaft is a key component in the rotating mechanism 25, which is responsible for transmitting the rotary motion on the rotating disc 251 to the transmission assembly, and the other end of the rotating shaft is connected to the transmission assembly, which also needs to ensure the synchronous transmission of the rotary motion. The transmission assembly is responsible for converting the rotary motion on the rotating shaft into a form suitable for the movement of the die mechanism 23, which can be gear transmission, belt transmission, chain transmission, worm transmission, etc. After the rotating disc 251 is driven to rotate, the rotary motion is transmitted to the transmission assembly through the rotating shaft, and the transmission assembly converts the motion into a form suitable for the die mechanism 23.

[0033] Further, the movable tray 32 comprises a first blocking strip 321, a second blocking strip 322 and a bottom plate 323, the first blocking strip 321 is located on one side of the bottom plate 323 consistent with the width direction of the fixed bottom support 31, the second blocking strip 322 is located on the other side of the bottom plate 323 consistent with the width direction of the fixed bottom support 31, the length of the first blocking strip 321 and the second blocking strip 322 is equal, and consistent with the inner width of the fixed bottom support 31, and the movable tray 32 can move in the length direction of the fixed bottom support 31. It should be noted that the first blocking strip 321 and the second blocking strip 322 are consistent with the length of the fixed bottom support 31, which does not mean that the length of the first blocking strip 321 and the second blocking strip 322 is the same as the inner width of the fixed bottom support 31, but means that the three are matched, so that the inner width of the fixed bottom support 31 is not much longer than the length of the first blocking strip 321 and the second blocking strip 322, and it is also enough for the first blocking strip 321 and the second blocking strip 322 to move in the length direction of the fixed bottom support 31.

[0034] In the above, as the main part of the movable tray 32, the bottom plate 323 carries the filter paper to be drilled and provides a flat and stable support surface. The first and second stoppers 321 and 322 are located on both sides of the bottom plate 323, respectively, and are consistent with the width direction of the fixed bottom support 31, ensuring the stability of the movable tray 32 in the fixed bottom support 31, preventing it from tipping or deviating during movement. The length of the first and second stoppers 321 and 322 is equal to the inner width of the fixed bottom support 31, not only enhancing the stability of the movable tray 32, but also ensuring that the movable tray 32 can move smoothly in the fixed bottom support 31 without being hindered. The presence of the stoppers also plays a limiting and positioning role, preventing the tray from moving out of the range of the fixed bottom support 31 during movement, thereby ensuring the safety and accuracy of the operation, effectively avoiding inaccurate drilling positions and low precision affecting the use effect of the filter paper. By adding the first and second stoppers 321 and 322, the design of the movable tray 32 is further improved, not only improving the stability and mobility of the tray, but also ensuring the accuracy and safety of the operation. Users can easily adjust the position of the tray according to actual needs to adapt to different drilling needs. Moreover, by adding the first and second stoppers 321 and 322, the overall stiffness of the movable tray 32 is improved, making it better resist deformation and vibration during drilling, thereby ensuring the accuracy of drilling and the quality of the filter paper. The design of the stoppers effectively prevents the tray from tipping and deviating during movement or use, avoiding equipment damage or operational accidents caused by unstable trays, and improving the overall safety of the operation. The matching design of the stoppers with the inner width of the fixed bottom support 31 ensures smooth movement of the tray in the fixed bottom support 31, reducing resistance and friction during movement, and improving operational efficiency. Through reasonable limiting design, the tray can accurately stay at the predetermined position, providing a stable support surface for drilling operations, ensuring the accuracy and consistency of drilling.

[0035] Further, the movable tray 32 further comprises a third blocking strip (not shown) and a fourth blocking strip (not shown), the third blocking strip is arranged on one side of the length direction of the bottom tray 323, and the fourth blocking strip is arranged on the other side of the length direction of the bottom tray 323, that is, the third blocking strip and the fourth blocking strip are arranged vertically with the first blocking strip 321 and the second blocking strip 322. The first blocking strip 321, the third blocking strip, the second blocking strip 322 and the fourth blocking strip are sequentially enclosed to form the enclosing wall of the bottom tray 323. The first blocking strip 321, the third blocking strip, the second blocking strip 322 and the fourth blocking strip are sequentially enclosed to form the enclosing wall of the bottom tray 323, which greatly enhances the overall structural integrity and stability of the movable tray 32, effectively resists external impact and vibration, and protects the filter paper in the movable tray 32 from being damaged. The existence of the enclosing wall also prevents the filter paper from sliding or shifting due to vibration or improper operation during drilling, ensuring the accuracy of drilling and the quality of the filter paper. The enclosing wall effectively isolates the inside of the tray from the outside space, avoiding the splashing of debris or liquid generated during drilling, and protecting the safety of the operator. At the same time, the design of the enclosing wall structure makes the inside of the tray more flat and closed, reducing the accumulation of dirt and debris.

[0036] As a preferred structure, two through holes 3231 are arranged on the bottom tray 323, and the straight line connected by the two through holes 3231 is parallel to the third blocking strip, that is, perpendicular to the first blocking strip 321 and the second blocking strip 322. By positioning and fixing through the through holes 3231, the assembly process between the movable tray 32 and the fixed bottom tray 31 can be greatly simplified, and the assembly efficiency and accuracy can be improved. Further, the fixed bottom tray 31 is provided with a plurality of protrusions (not shown), the number of the protrusions is greater than or equal to the number of the through holes 3231, and when the bottom tray 323 moves to the left or right along the width direction of the fixed bottom tray 31, the two through holes 3231 and two protrusions are one-to-one position corresponding, at this time the cutter die mechanism 23 and one of the through holes 3231 are position corresponding.

[0037] When the chassis 323 moves to the left or right along the width direction of the fixed base 31, the two through holes 3231 can one-to-one correspond to the two protruding positions, ensuring the stability and accuracy of the chassis 323 during movement, avoiding operation errors caused by position deviation. The cooperation between the protrusions and the through holes 3231 can serve as a simple fixing mechanism to prevent the chassis 323 from moving or shaking during drilling, and this fixing method is simple and effective, without the need for additional fasteners or locking devices. The number of protrusions is greater than or equal to the number of through holes 3231, and the chassis 323 can move in the width direction to multiple different positions on the fixed base 31, so that the chassis 323 can adapt to different drilling needs and equipment configurations, improving the flexibility and adaptability of the system. The explicit correspondence between the protrusions and the through holes 3231 helps to reduce the possibility of misoperation, and when operating, the worker can clearly see whether the chassis 323 has been correctly aligned with the protrusions, thereby avoiding operation errors caused by position deviation. When the two through holes 3231 of the chassis 323 correspond one-to-one to the two protrusions, the die mechanism 23 corresponds to the upper and lower positions of one of the through holes 3231, ensuring the accurate position of the die mechanism 23 during drilling, improving the accuracy and efficiency of drilling. By ensuring the accurate correspondence between the die mechanism 23 and the through holes 3231, this design helps to reduce drilling errors caused by position deviation.

[0038] The cutter mechanism 23 includes a motor, a drive shaft, a cutter head, and a cutter barrel 231. The motor is connected to the controller 21 and one end of the drive shaft, and the other end of the drive shaft is connected to the cutter head to drive the cutter head to rotate, and the cutter head is installed in the inner space of the cutter barrel 231. The cutter mechanism 23 is a key component in the drilling device, and its design and function are crucial to ensure the accuracy and efficiency of drilling. The cutter mechanism 23 includes a motor, a drive shaft, a cutter head, and a cutter barrel 231, which work together to complete the drilling operation. The motor is the power source of the cutter mechanism 23, providing the necessary torque and rotational speed to drive the drive shaft and cutter head to rotate. The motor is connected to the controller 21 and receives instructions from the controller 21 to start, stop, or adjust the rotational speed. At the same time, the output end of the motor is connected to one end of the drive shaft, transmitting power to the drive shaft. The drive shaft is a bridge connecting the motor and the cutter head, transmitting power from the motor to the cutter head to make it rotate. The drive shaft is usually designed as a rigid shaft to ensure stable power transmission. At the same time, one end is connected to the motor, and the other end is connected to the cutter head. The cutter head is the actual cutting tool in the drilling operation, and the cutter head is installed in the inner space of the cutter barrel 231 to ensure stable cutting of materials when rotating. The cutter head rotates under the drive of the drive shaft, generating enough cutting force to penetrate the material. The cutter barrel 231 is the protective shell and support structure of the cutter head, which ensures that the cutter head can stably cut materials when rotating and prevents debris from flying. The cutter barrel 231 is usually designed as a cylinder or a cone to adapt to different diameter drilling requirements. The inner space is used to install the cutter head and ensure that the cutter head does not interfere when rotating. When the controller 21 receives the drilling instruction, it sends a signal to the motor to start the motor. The motor starts to rotate and drives the drive shaft and cutter head to rotate.

[0039] Further, the drilling device 2 also comprises a paper pushing mechanism, which is arranged in the cutter barrel 231, and is used to push out the waste paper in the cutter barrel 231 after the cutting head cuts the air conditioner filter paper placed on the movable tray 32. The paper pushing mechanism is arranged inside the cutter barrel 231, for example, near the cutting head, which can ensure that the paper pushing mechanism can immediately contact the waste paper and push it out after the cutting head completes the cutting action. In an example, the paper pushing mechanism can comprise a push rod, a spring, a sliding rail, etc. working together to complete the function of pushing out the waste paper. When the cutting head rotates and cuts the air conditioner filter paper placed on the movable tray 32 under the instruction of the controller 21, waste paper will be generated during the cutting process and will be collected inside the cutter barrel 231. Once the cutting is completed, the paper pushing mechanism will be activated to contact the waste paper and push it to the outlet of the cutter barrel 231, and the waste paper will be pushed out of the cutter barrel 231 under the action of the paper pushing mechanism. The introduction of the paper pushing mechanism enables the drilling device 2 to automatically push out the waste paper after cutting the air conditioner filter paper, without the need for manual intervention, thereby improving the degree of automation of the device. By automatically pushing out the waste paper, the time for manual cleaning is reduced, and the operation efficiency of the device is improved. The waste paper is timely pushed out, avoiding accumulation in the working area, maintaining the cleanliness and safety of the working area. Automatically pushing out the waste paper reduces the downtime caused by cleaning the waste paper, and improves the utilization rate of the device.

[0040] As an improved embodiment based on the above, the paper pushing mechanism is a top rod 26, which is arranged in the cutter die mechanism 23, and one end of the top rod 26 extends into the cutter barrel 231, and when the cutter die mechanism 23 moves upward under the drive of the rotating disc 251, the top rod 26 pushes out the waste paper in the cutter barrel 231. The top rod 26 is designed as a long strip-shaped rod structure, and its material should be strong enough to withstand the pressure generated when the waste paper is pushed out, for example, steel material. Before the cutter die mechanism 23 starts to work, one end of the top rod 26 extends into the cutter barrel 231, but does not directly contact the waste paper. At this time, the waste paper is cut and left in the cutter barrel 231, and when the cutter die mechanism 23 moves upward under the drive of the rotating disc 251, since one end of the top rod 26 extends into the cutter barrel 231, it will contact the waste paper and push it out. As the top rod 26 continues to rise, the waste paper is gradually pushed out of the cutter barrel 231. Since the top rod 26 uses the upward movement of the cutter die mechanism 23 to push out the waste paper, it does not need an additional power source, thereby achieving efficient use of energy. The length of the top rod 26 should be moderate, which can ensure that it extends into the cutter barrel 231 to push out the waste paper, and also avoids interference with other parts of the cutter die mechanism 23.
