Description

Technical Field

[0001] This invention relates to the field of door and window profile cutting technology, specifically to a cutting device for door and window profiles. Background Technology

[0002] Window and door profiles are materials used to make window and door frames. They include various types such as aluminum alloy, PVC, and thermally broken aluminum. These profiles have regular shapes and good strength, sealing and decoration to meet the various functional requirements of windows and doors in buildings.

[0003] Cutting equipment for door and window profiles mainly includes CNC cutting equipment and manual cutting equipment. CNC cutting equipment, such as CNC saws, can precisely control the cutting size, angle, and speed through pre-programming. It has a high degree of automation and high cutting accuracy, and is suitable for large-scale, high-precision door and window profile cutting operations. Manual cutting equipment, such as hand saws, is simple to operate and highly flexible. It is mainly used for simple cutting of door and window profiles in small-batch production or on-site installation.

[0004] However, existing door and window profile cutting equipment still has the following drawbacks in the actual cutting and processing process:

[0005] Firstly, there is the challenge of handling metal dust. When cutting door and window profiles, a large amount of metal dust is inevitably generated. Currently, external vacuum cleaners are commonly used to collect this dust using negative pressure suction. However, in practice, this method has obvious drawbacks. During the cutting process, metal dust will splash in all directions due to centrifugal force. Since the negative pressure suction range of the vacuum cleaner is relatively fixed and limited, it is often powerless to handle those metal fragments that have splashed into the surrounding area. This results in a large amount of metal dust remaining in the working environment, making it impossible to achieve thorough cleaning. Both the collection efficiency and the final collection effect are unsatisfactory. In the long run, this will also have an adverse impact on the air quality in the workplace and the normal operation of equipment.

[0006] Secondly, noise pollution is a serious hazard. During the cutting operation, extremely loud noise is generated. The intensity of this noise often exceeds the comfort range that the human body can tolerate. When exposed to such a high-decibel noise environment for a long time, workers may experience physical discomfort symptoms such as tinnitus and hearing loss. At the same time, it may also cause psychological problems such as difficulty concentrating and increased mental stress, which greatly interferes with the workers' work status, reduces work efficiency, and brings great obstacles and troubles to the actual operation process of the entire cutting and processing. It may even lead to safety accidents due to worker operation errors caused by noise.

[0007] Thirdly, there is the risk of high temperature in the cutting blade. As the cutting work continues, the cutting blade will generate a lot of heat due to the intense friction between the cutting blade and the door and window profiles for a long time. This causes the cutting blade to heat up rapidly and reach a high temperature. The high temperature environment will change the metal structure of the cutting blade, resulting in a decrease in its hardness and toughness. The blade will also be more prone to wear, deformation, or even chipping. This will not only greatly reduce the sharpness of the cutting blade and affect the cutting accuracy and quality, but also significantly shorten the service life of the cutting blade and increase the cost of frequent cutting blade replacement for enterprises.

[0008] Fourth, static electricity triggers a chain of problems. During the cutting process, existing cutting equipment lacks an effective static electricity elimination mechanism. Static electricity generated on the profile surface will attract surrounding metal dust, causing the metal dust to adhere tightly to the profile surface. The negative pressure suction of ordinary vacuum cleaners is difficult to overcome the static attraction force and cannot effectively clean the static attracted metal dust. This not only damages the original smooth and beautiful surface of the profile, affecting the appearance quality and decorative effect of the product, but may also cause secondary pollution due to dust falling off during subsequent processing, assembly and use, bringing many inconveniences and potential quality hazards to actual production and product application.

[0009] Fifth, there is a lack of tool monitoring methods. Existing door and window profile cutting equipment generally lacks tool monitoring devices during the cutting process. When the tool gradually wears down during long-term cutting work, operators can only rely on experience and visual inspection to judge, or stop the machine and use professional measuring tools for inspection. This manual monitoring method has many drawbacks. On the one hand, manual judgment is prone to errors and oversights, making it difficult to detect minor wear of the tool in time. On the other hand, stopping the machine for inspection will interrupt the production process, reduce production efficiency, and increase production costs. Moreover, in the absence of real-time monitoring, if the tool wear is severe and not detected in time, it may lead to quality problems such as inaccurate cutting dimensions and rough profile cutting surfaces. In severe cases, it may also damage the cutting equipment and door and window profiles, causing unnecessary economic losses and production delays for enterprises. Summary of the Invention

[0017] Preferably, the outer wall of the dust collection box is equipped with an audible and visual alarm and a controller, and the other outer wall of the dust collection box is connected to a sliding door by a pin.

[0018] Preferably, a cylinder is provided on the top of the monitoring box, a guide plate is provided at the bottom of the inner cavity of the monitoring box, a connecting frame is slidably connected inside the guide plate, rubber pads are provided on the outer walls of both sides of the connecting frame, and multiple rubber pads are in contact with the outer walls of both sides of the monitoring box. A dust particle analysis sensor is also provided on the outer wall of the monitoring box, and a dust pump is provided at the bottom of the monitoring box. A dust suction hose is connected to the output end of the dust pump, and the end of the dust suction hose is connected to the outer wall of the dust collection box.

[0019] Preferably, a second suction pipe is provided on the top of each of the multiple dust collection boxes, and the ends of the first suction pipe and the second suction pipe are respectively connected to the outer wall of the monitoring box.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: During cutting, the electric push rod three can be activated to start working. It can push the cutting assembly carrying the protective part to slowly descend. During the descent, the protective soundproof box in the protective part will gradually approach and contact the door and window profile. At this time, the cutting motor will start and rotate at high speed. Driven by the cutting motor, the cutting blade can perform cutting operations on the profile. During the cutting process, as the cutting blade continues to penetrate into the profile, the telescopic frame below the protective soundproof box will slowly retract into the protective soundproof box under the resistance of the surface of the profile. In this way, the debris generated by the cutting blade during the cutting of the profile will be sealed in the limited space between the protective soundproof box and the support frame one. This unique design effectively blocks the metal debris that may fly, greatly reducing the situation of metal debris flying everywhere, so that the metal debris can be concentrated in a relatively enclosed space, thus bringing great convenience to the subsequent vacuuming work.

[0021] Because the cutting position is effectively enclosed by the protective soundproof box and support frame, it not only plays a good role in controlling metal debris, but also achieves significant results in noise control. During the cutting process, the intense friction between the cutting blade and the door and window profiles will generate a lot of harsh noise. The enclosed structure composed of the protective soundproof box and support frame can effectively block the transmission path of the noise and limit the noise to a small range, thereby greatly reducing the discomfort and harm caused to the staff by excessive noise, creating a relatively quiet and comfortable working environment for the staff, and improving the comfort and safety of the work.

[0022] Secondly, in the process of cutting door and window profiles, in order to effectively solve the problem of high temperature generated by the cutting blade due to long-term operation, the device introduces cooling vortex tube technology. External compressed gas is injected into multiple cooling vortex tubes 1 and 2. The multiple cooling vortex tubes 1 and 2 can convert the airflow into cold air. This cold air is then guided to multiple exhaust boxes, air outlet guide shell 1 and multiple air outlet guide shell 2 respectively. Through these guiding components, the cold air can be guided to the bottom and top of the door and window profiles, directly acting on the contact area between the cutting blade and the door and window profiles. This all-round cold air blowing method can efficiently absorb the heat generated during the cutting process, effectively reduce the temperature of the cutting blade, thereby significantly extending the service life of the blade, reducing the frequency of blade replacement due to high temperature, reducing production costs, and improving the continuity and stability of production.

[0023] Furthermore, while cooling the cutting tools with cold air, the device also integrates an electrostatic elimination function. The cold air blown towards the top of the window / door profile interacts with the electrostatic elimination rods installed inside the fixed cylinder. These rods release a large number of positive and negative ions, which, in conjunction with the cold air, neutralize the static charge on the profile surface, effectively eliminating static electricity. Similarly, the cold air blown towards the bottom of the window / door profile also eliminates static electricity as it passes through multiple electrostatic elimination rods. This design, which simultaneously eliminates static electricity during cooling, effectively solves the problem of static electricity on the profile surface during cutting. This design avoids surface contamination and quality degradation of profiles caused by electrostatic adsorption of metal dust. Furthermore, the airflow can further clean the metal dust adhering to the surface of the door and window profiles during the blowing process, peeling the metal dust off the profile surface and moving it with the airflow. Finally, under the suction of the dust pump, the airflow carrying the metal dust is orderly transferred into the dust collection box, which facilitates unified cleaning and treatment later. This integrated design further improves the cleanliness of door and window profiles after cutting, making the profile surface smoother and cleaner, significantly improving its appearance quality and meeting higher standards of production and processing requirements.

[0024] Furthermore, the device is equipped with a dust monitoring component during the collection of metal dust. When the airflow carrying metal dust passes through the guide plate, the guide plate changes the direction and speed of the airflow, allowing the airflow to pass more evenly through the monitoring area of ​​the dust particle analysis sensor. The dust particle analysis sensor uses high-precision laser diffraction or image recognition technology to monitor the size and shape of the metal dust in real time and quickly analyze key information such as particle size and shape. Once it detects that the dust particles are too large or irregularly shaped, it judges according to the pre-set logic that this may mean that the cutting tool is worn or the current cutting parameters are set incorrectly. At this time, the dust particle analysis sensor will quickly transmit the relevant data to the controller. After receiving the data, the controller will immediately activate the audible and visual alarm to issue an alarm signal, reminding the on-site staff to investigate and deal with the problem in time. In this way, it is possible to detect and take measures in the early stage of tool problems, effectively reducing further cutting damage to door and window profiles caused by improper tools or cutting parameters, and improving the product qualification rate and production quality.

[0035] Please see Figure 1-8 The present invention provides a technical solution:

[0036] A cutting device for door and window profiles includes a fixed base 100 and a control console 600. The bottom of the fixed base 100 is provided with a support foot 110. The outer wall of the control console 600 is provided with a high-voltage power supply 620 and a laser particle size analyzer 610. The bottom of the fixed base 100 is provided with a cooling vortex tube 120. The top of the fixed base 100 is provided with a clamping assembly, including a fixing plate 200. The outer wall of the rear of the fixed base 100 is provided with a fixing box 300. The outer wall of the fixing box 300 is provided with a lead screw motor 310. The output end of the lead screw motor 310 is connected to a lead screw.

[0037] It facilitates the use of a lead screw motor 310 to drive the cutting and support components for position adjustment;

[0038] A movable frame 320 is sleeved on the outer circumference of a lead screw. A support assembly is provided on the front outer wall of the movable frame 320. The support assembly includes a support frame 330, which extends to a fixed base 100. An electric push rod 350 is provided on the top of the movable frame 320. A descending frame 400 is connected to the output end of the electric push rod 350. A lead screw motor 410 is provided on the outer wall of the descending frame 400. A lead screw motor 410 is connected to the output end of the lead screw motor 410.

[0039] It facilitates the use of the lead screw motor 410 to drive the cutting assembly to cut the door and window profiles along the cutting line;

[0040] A cutting component is sleeved on the outer circumference of the lead screw. The cutting component includes a support frame 420. A protective component is fixedly connected to the outer wall of the support frame 420 by screws. The protective component includes a protective soundproof box 430. A dust collection component is set at the bottom of the fixed base 100. The dust collection component includes a dust collection box 500. A dust suction pump 547 is set on the outer wall in front of the dust collection box 500. A dust monitoring component is connected to the output end of the dust suction pump 547. The dust monitoring component includes a monitoring box 540.

[0041] Specifically, an electric push rod 210 is provided on the outer wall of the fixed plate 200. The output end of the electric push rod 210 is connected to a clamping frame 220. An electric push rod 230 is provided on the top of the clamping frame 220. The output end of the electric push rod 230 is connected to a clamping plate 240, which facilitates the cutting of door and window profiles.

[0042] Furthermore, the support frame 330 has a groove 331 on its top, and springs 332 are installed at the bottom of the inner cavity of multiple grooves 331. The ends of multiple springs 332 are connected to exhaust boxes 333. The outer walls of multiple exhaust boxes 333 are provided with air supply pipes 335. Static eliminator rods 334 are installed inside multiple exhaust boxes 333. The outer walls of multiple exhaust boxes 333 are also provided with air supply pipes 335. The ends of multiple air supply pipes 335 are connected to the cooling exhaust end of multiple cooling vortex tubes 120.

[0043] In some embodiments, the principle of multiple cooling vortex tubes 120 and multiple cooling vortex tubes 441 is that compressed gas expands and accelerates through the nozzle and is tangentially injected into the vortex chamber to form a free vortex. Due to interlayer friction, the energy of the central part of the airflow is transferred to the outer layer airflow. The kinetic energy of the central airflow decreases and the temperature drops, while the kinetic energy of the outer layer airflow increases and is partially converted into heat energy. Then, the central layer airflow with a lower temperature is drawn out from one end through the central orifice plate to form a cold airflow, and the outer layer airflow with a higher temperature is drawn out from the other end through the control valve to form a hot airflow. Its structure mainly includes a nozzle that accelerates the gas expansion, a vortex chamber that forms a free vortex, a cold end pipe that draws out the cold airflow, a hot end pipe that draws out the hot airflow, and a hot end regulating valve that regulates the flow rate of the hot airflow. All of the above belong to the prior art.

[0044] In some embodiments, the static eliminator rod 334 and the static eliminator rod 442 are mainly composed of electrode needles and a shell. The principle is to use a high-voltage power supply 620 to apply voltage to the electrode needles, causing a corona discharge phenomenon at the tip of the electrode needles, releasing a large number of positive and negative ions. These ions will interact with the static charge in the cutting position environment under the traction of the cold air. Opposite charges attract each other, thereby neutralizing the static charge on the surface of the object and achieving the purpose of eliminating static electricity. The principle is existing technology. The control console 600 is mainly used to control the device.

[0045] Furthermore, the bottom of the support frame 330 is provided with a dust collection seat 336, the top of the dust collection seat 336 is provided with a dust collection port 337, and the outer wall of the dust collection seat 336 is also provided with a dust collection pipe 338, which facilitates the collection of metal dust generated by cutting the bottom of the door and window profiles.

[0046] Furthermore, a cutting motor 421 is installed on the outer wall of the support frame 420. The output end of the cutting motor 421 is connected to a mounting plate 422. A cutting blade 423 is fixedly connected to the outer wall of the mounting plate 422 with screws, which facilitates the cutting of door and window profiles.

[0047] It is worth noting that the protective soundproof box 430 is equipped with a dust collection box 450 on the top, and a fixed cylinder 440 is also provided on the outer wall of the protective soundproof box 430. The outer wall of the fixed cylinder 440 is equipped with a second cooling vortex tube 441, and the inner wall of the fixed cylinder 440 is equipped with a second static elimination rod 442. The outer wall of the movable frame 320 is also provided with a through-hole 340 that matches the fixed cylinder 440. The through-hole 340 facilitates the fixed cylinder 440 to pass through, reducing the impact of the second cooling vortex tube 441 on its cutting stroke.

[0048] It is worth noting that the top of the protective soundproof box 430 is slidably connected to a telescopic frame 460. The inner wall of the telescopic frame 460 is provided with an air outlet guide shell 1 470 and an air outlet guide shell 2 480. The outer walls of the air outlet guide shell 1 470 and the air outlet guide shell 2 480 are both provided with air inlet pipes 471. The ends of the multiple air inlet pipes 471 are connected to the outer wall of the fixed cylinder 440 to facilitate the delivery of cold air.

[0049] In some embodiments, the bottom of the telescopic frame 460 is also rotatably connected to a traction roller to facilitate rolling traction when cutting along the door and window profile.

[0050] In addition, the outer wall of the dust collection box 500 is equipped with an audible and visual alarm 510 and a controller 520, and the other outer wall of the dust collection box 500 is connected to a sliding door 530 by a pin.

[0051] In some embodiments: the audible and visual alarm 510 is prior art, and its dust particle analysis sensor 545, controller 520, laser particle size analyzer 610 and audible and visual alarm 510 are electrically connected in series to facilitate timely monitoring and alarm.

[0052] In addition, a cylinder 541 is installed on the top of the monitoring box 540, a guide plate 542 is installed at the bottom of the inner cavity of the monitoring box 540, a connecting frame 543 is slidably connected inside the guide plate 542, rubber pads 544 are installed on the outer walls of both sides of the connecting frame 543, and multiple rubber pads 544 are in contact with the outer walls of both sides of the monitoring box 540. A dust particle analysis sensor 545 is also installed on the outer wall of the monitoring box 540, and a dust pump 546 is installed at the bottom of the monitoring box 540. A dust suction hose is connected to the output end of the dust pump 546, and the end of the dust suction hose is connected to the outer wall of the dust collection box 500.

[0053] In some embodiments, the dust particle analysis sensor 545 mainly consists of a light source, a detection cavity, a photodetector, and a signal processing circuit. Its principle is based on light scattering. The light source emits light that irradiates the dust particles, causing them to scatter. Because particles of different sizes have different scattering characteristics, larger particles scatter stronger light. The photodetector receives the scattered light and converts it into an electrical signal. After processing by the signal processing circuit, information such as particle size and concentration is obtained. This information is then compared with preset standard data in the laser particle size analyzer 610. For metal dust, when the cutting blade is worn, the size distribution of the generated metal dust particles differs from the normal situation. The proportion of larger particles or particles with specific abnormal sizes increases. By comparing the particle information detected by the dust particle analysis sensor 545 with the standard particle data under normal operating conditions, the degree of cutting blade wear can be determined, thereby reflecting whether the operating coefficient deviates from the normal range. This provides a basis for equipment maintenance and process adjustment. All of the above belong to the prior art.

[0054] In addition, multiple dust collection boxes 450 are equipped with a second dust collection pipe 451 on their tops, and the ends of the first dust collection pipe 338 and the second dust collection pipe 451 are respectively connected to the outer wall of the monitoring box 540.

[0055] In some embodiments, the cylinder 541 can be started by an external control console, thereby driving the connecting frame 543 carrying the rubber pad 544 to move down and clean the monitoring port of the dust particle analysis sensor 545. The cleaned dust can be transferred to the dust collection box 500 by a dust pump 546 for collection. The guide plate 542 can further reduce the direct adhesion of metal dust to the monitoring port of the dust particle analysis sensor 545 and its impact on monitoring. The cylinder 541 can be timed by the control console 600. The control console 600 is equipped with a PLC timer and is electrically connected to the cylinder 541, so that the dust particle analysis sensor 545 can be cleaned at regular intervals to achieve continuous monitoring. The device can be powered by an external conventional power supply.

[0056] The working principle of this invention is as follows: When cutting door and window profiles, the profiles are first placed stably between two clamping components. These components are driven by multiple electric push rods 210. Upon receiving a control command, the electric push rods 210 drive the two connected clamping frames 220 to move slowly until they are tightly fitted from both sides of the profile, achieving stable lateral clamping. After lateral clamping, to further ensure the stability of the profiles during cutting, multiple electric push rods 230 activate, pushing two clamping plates 240 to limit and fix the top of the profiles. Thus, the profiles are securely fixed on the cutting platform, effectively preventing displacement and shaking during cutting, greatly improving cutting accuracy and safety. Once the profiles are firmly fixed, the cutting process officially begins. The lead screw motor 310 serves as the power source for the lateral movement of the cutting components. Upon receiving a start signal, the cutting and support components can move under the drive of the lead screw motor 310. Once the material reaches the preset cutting position, the electric push rod 350 starts working, pushing the cutting assembly carrying the protective component to descend slowly. During the descent, the protective soundproof box 430 in the protective component gradually approaches and contacts the door and window profile. At this time, the cutting motor 421 starts and rotates at high speed. Driven by the cutting motor 421, the cutting blade can perform cutting operations on the profile. During the cutting process, as the cutting blade 423 continues to penetrate into the profile, the telescopic frame 460 below the protective soundproof box 430 will slowly retract into the protective soundproof box 430 due to the resistance of the surface of the profile. In this way, the debris generated by the cutting blade 423 during the cutting of the profile will be sealed in the limited space between the protective soundproof box 430 and the support frame 330. This unique design effectively blocks the possible flying metal debris, greatly reducing the situation of metal debris flying everywhere, and allowing the metal debris to be concentrated in a relatively enclosed space, thus bringing great convenience to the subsequent vacuuming work.

[0057] Because the cutting position is effectively enclosed by the protective soundproof box 430 and the support frame 330, it not only plays a good role in controlling metal debris, but also achieves significant results in noise control. During the cutting process, the intense friction between the cutting blade 423 and the door and window profiles will generate a lot of harsh noise. The enclosed structure composed of the protective soundproof box 430 and the support frame 330 can effectively block the transmission path of noise and limit the noise to a small range. This greatly reduces the discomfort and harm caused to the staff by excessive noise, creates a relatively quiet and comfortable working environment for the staff, improves the comfort and safety of the work, and thus helps to improve work efficiency and work quality.

[0058] Secondly, in the process of cutting door and window profiles, in order to effectively solve the problem of high temperature generated by the cutting blade due to long-term operation, the device innovatively introduces cooling vortex tube technology. External compressed gas is injected into multiple cooling vortex tubes 120 and 441. The multiple cooling vortex tubes 120 and 441 can convert the airflow into cold air. This cold air is then guided to multiple exhaust boxes 333, air outlet guide shell 470 and multiple air outlet guide shell 480 respectively. Through these guiding components, the cold air can be guided to the bottom and top of the door and window profiles, directly acting on the contact area between the cutting blade 423 and the door and window profiles. This all-round cold air blowing method can efficiently absorb the heat generated during the cutting process, effectively reduce the temperature of the cutting blade, thereby significantly extending the service life of the blade, reducing the frequency of blade replacement due to high temperature, reducing production costs, and improving the continuity and stability of production.

[0059] Furthermore, while cooling the cutting tool with cold air, the device also integrates an electrostatic elimination function. The cold air blown towards the top of the window / door profile interacts with the electrostatic elimination rods 442 installed inside the fixing cylinder 440. These rods release a large number of positive and negative ions, which, in conjunction with the cold air, neutralize the static charge on the profile surface, effectively eliminating static electricity. Similarly, the cold air blown towards the bottom of the window / door profile also eliminates static electricity as it passes through multiple electrostatic elimination rods 334. This design, which simultaneously eliminates static electricity during the cooling process, not only effectively solves the problem of static electricity on the profile surface during cutting. The design avoids surface contamination and quality degradation of the profiles caused by electrostatic adsorption of metal dust. Furthermore, the airflow can further clean the metal dust adhering to the surface of the door and window profiles, peeling the metal dust off the profile surface and moving it with the airflow. Finally, under the suction of the dust pump 546, the airflow carrying the metal dust is orderly transferred into the dust collection box 500 for easy unified cleaning and treatment later. This integrated design further improves the cleanliness of the door and window profiles after cutting, making the profile surface smoother and cleaner, significantly improving its appearance quality and meeting higher production and processing standards.

[0060] Furthermore, the device is equipped with a dust monitoring component during the collection of metal dust. When the airflow carrying metal dust passes through the guide plate, the guide plate changes the direction and speed of the airflow, allowing the airflow to pass more evenly through the monitoring area of ​​the dust particle analysis sensor 454. The dust particle analysis sensor 545 uses high-precision laser diffraction or image recognition technology to monitor the size and shape of the metal dust in real time and quickly analyze key information such as the size and shape of the dust particles. Once it detects that the dust particles are too large or irregularly shaped, according to the pre-set logic, this may mean that the cutting tool is worn or the current cutting parameters are set incorrectly. At this time, the dust particle analysis sensor 545 will quickly transmit the relevant data to the controller 520. After receiving the data, the controller 520 will immediately activate the audible and visual alarm 510 to issue an alarm signal, reminding on-site personnel to investigate and deal with the problem in time. In this way, the problem of the cutting tool can be detected and addressed in the early stage, effectively reducing further cutting damage to the door and window profiles caused by improper cutting tools or cutting parameters, and improving the product qualification rate and production quality.
