Description

Technical Field

[0001] This invention relates to the field of profile cutting technology, and more specifically to a cutting device for manufacturing integrated plastic sunshade energy-saving doors and windows. Background Technology

[0002] With the increasing demand for building energy conservation, integrated plastic shading energy-saving doors and windows require precise multi-angle cutting of plastic frames and metal shading components, but existing cutting devices have significant shortcomings:

[0003] Angle positioning is cumbersome: Switching between common angles such as 45° and 90° requires frequent changes of fixtures, which is time-consuming and the accuracy depends on manual operation. There is a lack of a quick positioning structure for the 45° reference angle.

[0004] Poor material compatibility: A single cooling and chip removal solution cannot accommodate both plastics (coolant is prone to deformation) and metals (air cooling is insufficient and saw blades wear out quickly).

[0005] Weak linkage: Cutting and waste, coolant recovery are controlled independently, requiring manual or additional equipment to open and close the collection door, and coolant is mostly discharged at once, resulting in serious waste;

[0006] Complex structure and high energy consumption: Some devices rely on additional motors and sensors to improve their functions, resulting in high energy consumption, many points of failure, and increased maintenance costs and downtime.

[0007] In summary, current cutting devices for manufacturing integrated plastic shading energy-saving doors and windows have significant shortcomings in terms of convenient angle positioning, material compatibility, mechanism linkage, and resource utilization. There is an urgent need for a cutting technology solution that can take into account multi-angle rapid positioning, material differentiation processing, linkage waste recycling, and energy saving, so as to meet the development needs of efficient, high-quality, and green manufacturing of such doors and windows.

[0017] The technical effects and advantages of this invention are as follows:

[0018] This invention features a linkage mechanism that drives the double-door switch via the lifting action of the cutting mechanism. The entire process relies on the mechanical transmission of a strip-shaped sliding block, a bidirectional rack and pinion, and a gear set, eliminating the need for additional power components such as motors and cylinders. This simplifies the device structure, reduces energy consumption, and avoids the risk of power component failure. Furthermore, the door opens during cutting to allow waste material and coolant to fall, while closing it during standby prevents foreign objects from entering the box, thus balancing functionality with tabletop cleanliness.

[0019] This invention addresses the low hardness of plastic profiles by using a cutting arm that sprays only compressed air. This air can remove the small amount of heat generated during cutting and blow away debris between the teeth. When cutting metal profiles, reverse pressure triggers a gas-liquid mixture spray, which precisely cools the metal and, combined with airflow, thoroughly washes away metal debris. This invention is suitable for cutting two core materials, extending the saw blade's lifespan by 50% and improving the stability of cutting quality by 40%.

[0020] This invention features a collection box where coolant, after initial filtration of metal debris through a built-in filter, flows back to the circulation pump via a return port. After being pressurized, it is then re-delivered to the cutting arm, achieving a 100% closed-loop circulation. Compared to traditional open-loop coolant usage, this reduces coolant waste by over 80%, avoids wastewater discharge, eliminates the need for additional wastewater treatment, meets green production standards in the door and window manufacturing industry, and lowers environmental compliance costs.

[0021] This invention features an X-shaped plate with adjacent plates fixed at a 45° angle, precisely matching the 45° bevel and 90° right-angle cut requirements of door and window profiles. Combined with four U-shaped positioning plates, it eliminates the need for frequent clamp changes; angle alignment can be achieved simply by fitting different plates together. This adapts to door and window profiles of varying thicknesses, reducing clamp adjustment time. Simultaneously, the U-shaped structure ensures that the profiles are clamped without deviation, and the cutting angle error is controlled within ±0.5°, guaranteeing splicing accuracy.

[0041] Working principle of the invention:

[0042] First, based on the target cutting angle of 45° or 90° for the profile to be cut, align the edge of the profile to be cut with the corresponding side of the X-shaped plate 102. When the target angle is 45°, place the profile into the inclined U-shaped positioning plate 1021, at which point the angle between the profile to be cut and the plate is 45°. When the target angle is 90°, place the profile into the horizontal U-shaped positioning plate 1021, making the profile to be cut perpendicular to any part of the X-shaped plate 102 at 90°. After aligning the angles, clamp and fix the profile using the U-shaped positioning plates 1021 on the upper surfaces of the four limbs of the X-shaped plate 102. The opening size of the U-shaped positioning plate 1021 is adapted to the thickness of common door and window profiles, allowing for stable positioning of profiles of different sizes without changing the clamps, ensuring no profile shift during the cutting process and guaranteeing the accuracy of the cutting angle.

[0043] When the operator pushes the cutting mechanism 2 to rotate downwards around the base 103 of the arched rotating block 203, the saw blade 2014 approaches the profile to be cut. The strip-shaped sliding block 2031 at the rear of the cutting mechanism 2 is lifted upwards along with the cutting mechanism 2. The sliding groove 2032 inside the strip-shaped sliding block 2031 slides and engages with the sliding rod 3011 of the linkage mechanism 3. The upward lifting of the sliding groove 2032 will drive the sliding rod 3011 to move upwards, which in turn will drive the bidirectional rack 301, which is fixedly connected to the sliding rod 3011, to move upwards. The two sides of the bidirectional rack 301 mesh with two large gears 302 respectively. The upward movement of the bidirectional rack 301... Two large gears 302 are driven to rotate synchronously around a short shaft 3021 at their center. Each large gear 302 is meshed with a small gear 303 on the other side. The rotation of the large gears 302 drives the small gears 303 to rotate in the opposite direction around a long shaft 3031 at their center. The long shaft 3031 is fixedly connected to the double door 101. The rotation of the small gears 303 drives the long shaft 3031 to rotate synchronously, thereby driving the double door 101 to flip down and open around the door shaft hole 105, so that the opening in the middle of the workbench 1 is open. The cutting debris and coolant can fall into the collection box 104 below through the opening.

[0044] When cutting, the servo motor 2055 is started. The rotation of the servo motor 2055 will drive the drive wheel 2053 to rotate. The rotation of the drive wheel 2053 will drive the driven wheel 2052 to rotate through the transmission belt 2054. The driven wheel 2052 will drive the cutting spindle 2013 to rotate. The rotation of the cutting spindle 2013 will drive the saw blade 2014 to rotate, thereby cutting the profile.

[0045] When cutting plastic profiles, due to the low hardness and low cutting resistance of plastic profiles, the reverse pressure generated by the saw blade 2014 on the cutting arm 202 during the cutting process is small. This pressure is insufficient to overcome the elastic force of the first spring 20222 at the rear end of the annular push rod 2022. The annular push rod 2022 maintains its initial position, and the limiting block 20221 at its front end is engaged in the limiting groove 20211 of the valve body 2021. The annular push rod 2022 does not push the control piston 2023 to move, and the control piston 2023 does not push the valve core 2024. As a result, the valve core 2024 will block the liquid inlet hole 20213 of the valve body 2021, and the coolant passage is in a closed state. At this time, the compressed air generated by the air compressor 501 of the air tank 5 first passes through the air outlet 5. 02 The air enters the first air inlet 20214 of the valve body 2021 through the hose, then enters the second air inlet 20241 of the valve core 2024, and then enters the internal chamber of the valve body 2021 through the air outlet 20232 of the control piston 2023. It is then delivered to the liquid outlet pipe 204 through the first sealing ring 2025 from the liquid outlet 20212 of the valve body 2021, and finally delivered to the nozzle 2041. The compressed air is directionally sprayed onto the surface of the saw blade 2014 through the nozzle 2041. On the one hand, it removes the small amount of heat generated by cutting plastic, avoiding local overheating of the saw blade 2014 and plastic adhesion. On the other hand, the airflow impact force blows away the plastic debris remaining between the teeth of the saw blade 2014, ensuring that the saw blade 2014 maintains its cutting sharpness.

[0046] When cutting metal profiles, due to the high hardness and cutting resistance of the metal profiles, the reverse pressure generated by the saw blade 2014 on the cutting arm 202 during the cutting process is relatively large. This pressure is greater than the elastic force of the first spring 20222 at the rear end of the annular push rod 2022. The valve body 2021 switches states: the reverse pressure pushes the annular push rod 2022 to move backward along the axial direction of the valve body 2021, compressing the first spring 20222. The rear end of the annular push rod 2022 then engages with the control piston 2023, synchronously pushing the control piston 2023 to move backward. The control piston 2023 pushes the valve core 2024 to move backward, thereby opening the coolant passage. The coolant from the coolant circulation pump 4 enters the hose through the outlet 401, then enters the second sealing ring 2026, and then enters the valve body 2021 through the inlet hole 20213. The coolant is then mixed with compressed air in the internal chamber of valve body 2021. Since the compressed air remains open, the compressed air and coolant mix in the internal chamber of valve body 2021 to form a gas-liquid mixture. The gas-liquid mixture flows out through the air outlet 20232 of control piston 2023, and then is transported to the liquid outlet pipe 204 through liquid outlet 20212. Finally, it is sprayed onto the cutting part of saw blade 2014 through nozzle 2041. The coolant acts directly on the contact point between saw blade 2014 and metal profile, quickly absorbing the large amount of heat generated by metal cutting, avoiding wear of saw blade 2014 due to overheating, and extending the service life of saw blade 2014. The impact force of the gas-liquid mixture is greater than that of compressed air alone, which can thoroughly wash away the metal debris remaining between the teeth of saw blade 2014, and push the debris along with the coolant to the opening in the middle of worktable 1 and fall into collection box 104.

[0047] After cutting is completed, the operator lifts the cutting mechanism 2 upwards, causing the cutting mechanism 2 to reset around the arched rotating block 203. The strip-shaped sliding block 2031 moves downwards as the cutting mechanism 2 moves upwards. The sliding groove 2032 moves downwards, causing the sliding rod 3011 to move downwards, which in turn causes the bidirectional rack 301 to slide downwards, thereby driving the large gear 302 and the small gear 303 to rotate in the opposite direction. The reverse rotation of the small gear 303 causes the long rotating shaft 3031 to rotate in the opposite direction, causing the double door 101 to flip upwards and close around the door shaft hole 105, sealing the opening in the middle of the workbench 1, preventing foreign objects from falling into the collection box 104 when not cutting, and keeping the upper surface of the workbench 1 clean.

[0048] Finally, the coolant in the collection box 104 will be filtered. The filtered coolant will enter the hose through the return port 1041 at the rear, and then enter the coolant circulation pump 4 through the inlet port 402. It can participate in the gas-liquid mixture injection of the next metal profile cutting to achieve zero waste circulation of coolant.

[0049] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
