Description

Technical Field

[0001] The invention belongs to the field of door and window profile processing, in particular to a door and window profile sawing device and a sawing process. Background Art

[0002] Door and window profiles refer to the raw materials used to make doors and windows. Their types and characteristics directly affect the quality and performance of doors and windows. The main ones are aluminum alloy profiles, plastic steel profiles and fiberglass profiles.

[0003] Traditional door and window profiles are generally long strips. Before being processed into doors and windows, the long strips of profiles need to be cut into four sides of the doors and windows, and then the four sides are connected to each other into a rectangle to complete the basic frame of the doors and windows.

[0004] Traditional cutting devices generally use cutting workpieces to directly cut the profile to be processed. The cutting process requires clamping both ends of the profile to be processed, but excessive clamping can easily cause deformation of the hollow profile to be processed, and the cutting process is prone to vibration. The profile to be processed is relatively long, which can easily cause large vibration and noise in the profile to be processed at the entry end.

[0005] To this end, the present invention provides a door and window profile sawing device and a sawing process. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: a door and window profile sawing device described in the present invention comprises a processing box, a group of rotatable driving rollers are arranged at both ends and inside of the processing box, each group comprises two driving rollers symmetrical up and down, the profile to be processed passes through the two driving rollers, both ends of the processing box are provided with processing holes for passing the profile to be processed, a vertical rotatable saw blade is arranged inside the processing box, an adjustable seat with adjustable position is installed on one side of the saw blade, and an expandable filling bag is arranged on the inner side of the driving roller;

[0008] The profile to be processed is passed through the processing box, and at the same time, the profile to be processed passes through three sets of driving rollers. The cutting angle of the saw blade is controlled by the adjustment seat. Because both ends of the traditional door and window profiles have a cutting angle of 45 degrees, when the two profiles are vertically connected, the cutting angles of the two sections can be completely connected; then the adjustment seat drives the saw blade to sink, and the rotating saw blade first cuts off the profile to be processed, and then the adjustment seat and the saw blade rise, and then sink after adjusting the angle and position, cutting the profile to be processed, and cutting an equilateral triangle of waste from the entire profile to be processed. After that, the profile to be processed on the right end is transported outward by the driving roller on the right end, and the subsequent profile to be processed is transported to the right by the inside of the processing box and the driving roller on the left end. Since the upper and lower sides of the profile to be processed are different in shape, in order to ensure that the front and back of the doors and windows after splicing are the same, the method of cutting out equilateral triangles of waste is used, which is also the most material-saving method. At the same time, in order to ensure The stability of the profile to be processed during the cutting process, the driving roller presses the profile to be processed up and down at the beginning, and the rotating driving roller can control the horizontal movement of the profile to be processed. When the profile to be processed moves to the processing position, compressed air is added to the filling bag, so that the filling bag and the driving roller expand outward as a whole, thereby pressing the profile to be processed. At the same time, during the cutting process, the profile to be processed will vibrate. If a driving roller made of solid material is used to press the profile to be processed, the vibration generated can only be applied to the shaft of the driving roller and the driving member of the driving roller, resulting in a reduction in the service life of the driving roller, while the hollow filling bag can be properly squeezed to consume the energy generated by the vibration, thereby reducing the impact of long-term vibration on parts. Through this setting, a scientific and low-loss cutting processing method is guaranteed, and the cutting process of the profile to be processed is realized in a stable and orderly manner. While reducing the impact of vibration on the equipment, it also reduces the noise caused by vibration.

[0009] Preferably, an isolation plate is provided on the inner side of the processing box, and the isolation plate is arranged horizontally. A plurality of groups of hydraulic rods are fixedly connected to the bottom of the processing box, and each group includes two hydraulic rods. A support plate is fixedly connected between the top movable ends of the two hydraulic rods in each group, and the support plate penetrates the isolation plate. The waste materials that fall after cutting will fall onto the isolation plate. A material taking door is provided on one side of the processing box for taking out the waste materials inside. The support plate is lifted upward by the plurality of groups of hydraulic rods to support the bottom of the profile to be processed, thereby ensuring the horizontal processing state of the profile to be processed and further improving the processing quality.

[0010] Preferably, an adjustment cabinet is fixedly connected to the top of the processing box, and a moving seat is slidably connected to the top of the adjustment cabinet, a hydraulic rod three is connected between the adjustment cabinet and the moving seat, a servo motor one is fixedly connected to the bottom of the moving seat, a hydraulic rod two is fixedly connected to the bottom of the servo motor one, and the bottom of the hydraulic rod two is fixedly connected to the adjustment seat, and a servo motor two for driving the saw blade to rotate is installed in the adjustment seat, and the hydraulic rod two and the adjustment seat are driven to rotate by the servo motor one, so as to adjust the cutting angle of the saw blade, and the lifting and cutting process of the saw blade is adjusted by extending and shortening the hydraulic rod two, and the translation of the moving seat is controlled by the hydraulic rod three, so as to adjust the position of the saw blade horizontally, so as to achieve the effect of the saw blade cutting the profile to be processed at the specified position.

[0011] Preferably, a driving motor for driving the driving roller to rotate is installed at one end of the driving roller, and an inclined electric telescopic rod is fixedly connected to the top of the processing box. Support arms for adjusting the position of the driving roller are provided at both ends of the driving roller. The driving motor drives the driving roller to rotate, and the support arm can adjust the distance between two driving rollers in the same group. In this way, when processing profiles to be processed of different thicknesses, the distance between the two driving rollers can be adjusted, and the profile to be processed can be firmly clamped in the middle and used for transportation and fixation. When fixing, the inclined electric telescopic rod is extended to press the profile to be processed from the right end above the support plate, and an elastic pad is fixed to the end of the electric telescopic rod to reduce rigid contact with the profile to be processed.

[0012] Preferably, the interior of the driving roller is hollow, and the driving roller includes a center rod, the filling bag is wrapped around the outside of the center rod, the outside of the center rod is a protective layer, the protective layer is made of elastic material, the driving motor is connected to one end of the center rod, the material of the protective layer can be hard rubber, which is deformable, but the force required for deformation is large, which is much greater than the force required for the filling bag. As the filling bag expands, the protective layer is squeezed outward, and the protective layer squeezes the profile to be processed. With this arrangement, the expansion amplitude is always within a controllable range, and excessive expansion will not cause extrusion and deformation of the profile to be processed, and the filling bag is evenly stressed, not easy to break or leak.

[0013] Preferably, a micro air pump is fixedly connected to the other end of the center rod, and a three-way solenoid valve is connected to the output end of the micro air pump. A channel for transmitting air is opened inside the center rod, and a plurality of valve valves connected to the filling bag are installed on the surface of the center rod. During the rotation of the driving roller, the three-way solenoid valve can be remotely controlled. When it is necessary to fix the profile to be processed, the three-way solenoid valve connects the micro air pump and the filling bag, and at the same time, the micro air pump is turned on to fill air into the filling bag, so that the driving roller expands and presses the profile to be processed. When the profile to be processed needs to be moved, the micro air pump is remotely controlled to be closed, and at the same time, the three-way solenoid valve connects the outside world and the filling bag to relieve part of the internal pressure, thereby reducing the force of the driving roller pressing the profile to be processed, so that the profile to be processed can move normally.

[0014] Preferably, the support arm is arranged in an arc shape, one end of the support arm is fixedly connected with a rotating shaft, the rotating shaft is sleeved on the outside of the center rod, and the other end of the support arm is rotatably connected to the processing box. The support arm is used to support both sides of the center rod. The setting of the rotating shaft allows the center rod to rotate normally while being supported.

[0015] Preferably, there are two support arms at one end of the driving roller close to the driving motor, and a connecting rod is fixedly connected between the two support arms. A motor box for driving the two connecting rods to rotate synchronously is provided on one side of the connecting rod. In order to facilitate the adjustment of the spacing between the two driving rollers, the stepper motor in the motor box can simultaneously drive the two connecting rods in the same group to rotate in opposite directions at the same time, so that the two driving rollers can be controlled to open or merge at the same time, thereby controlling the spacing between the two driving rollers, so as to adapt to various widths of profiles to be processed.

[0016] Preferably, an integration plate is provided at one end of the connecting rod away from the driving roller, and four rotating rods are fixedly connected to the integration plate, and four mutually meshing gears are fixedly connected to the ends of the rotating rods, and two gears located at the upper and lower ends of the four gears are respectively fixedly connected to the two connecting rods, and a worm wheel is fixedly connected to the outer side of one of the rotating rods located in the middle position among the four rotating rods, and a worm is fixedly connected to the output end of the motor box, and the worm is meshed with the worm wheel. As the stepping motor in the motor box drives the worm to rotate, the worm wheel is driven to rotate. Since the four gears are meshed with each other, when one gear rotates, the two gears located at the upper and lower ends will rotate synchronously in the opposite direction. This not only achieves the effect of controlling the distance between the two driving rollers, but also the worm gear has self-locking ability, and the gear cannot drive the worm to rotate in the opposite direction. In addition, the self-locking ability of the stepping motor itself ensures that the support arm and the driving roller will not be offset during the processing.

[0017] A door and window profile sawing process, which is applicable to the door and window profile sawing device described above, and specifically comprises:

[0018] S1: The profile to be processed is passed through the processing box, and at the same time, the profile to be processed passes through three sets of driving rollers, and the servo motor 1 drives the hydraulic rod 2 and the adjustment seat to rotate, thereby adjusting the cutting angle of the saw blade, and the lifting and cutting process of the saw blade is adjusted by the extension and contraction of the hydraulic rod 2, and the translation of the moving seat is controlled by the hydraulic rod 3, thereby adjusting the position of the saw blade horizontally;

[0019] S2: The adjustment seat drives the saw blade to sink, and the rotating saw blade first cuts the profile to be processed, and then the adjustment seat and the saw blade rise, and then sink after adjusting the angle and position, cutting the profile to be processed, and cutting out an equilateral triangle of waste from the entire profile to be processed;

[0020] S3: The rotating driving roller can control the horizontal movement of the profile to be processed. When the profile to be processed moves to the processing position, compressed air is added to the filling bag, so that the filling bag and the driving roller expand outward as a whole, thereby pressing the profile to be processed. When the cutting is completed, the air in the filling bag is released to allow the profile to be processed to be transported normally;

[0021] S4: As the stepper motor in the motor box drives the worm to rotate, it drives the worm wheel to rotate. Since the four gears are meshed with each other, when one gear rotates, the two gears at the upper and lower ends will rotate synchronously in the opposite direction.

[0022] S5: The synchronous counter-rotation of the two gears at the upper and lower ends will drive the two connecting rods to rotate in the opposite direction at the same time, so that the two driving rollers can be controlled to open or merge at the same time, thereby controlling the distance between the two driving rollers to adapt to various widths of profiles to be processed.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The door and window profile sawing device and sawing process described in the present invention drives the saw blade to sink through the adjusting seat, and the rotating saw blade first cuts off the profile to be processed, and then the adjusting seat and the saw blade rise, and sink again after adjusting the angle and position, to cut the profile to be processed, and cut an equilateral triangle of waste from the entire profile to be processed, and then the profile to be processed at the right end is transported outward by the driving roller at the right end, and the subsequent profile to be processed is transported to the right by the inside of the processing box and the driving roller at the left end. Since the upper and lower surfaces of the profile to be processed are different in shape, in order to ensure that the front and back of the spliced ​​doors and windows are the same, a method of cutting out equilateral triangles of waste is used, which is also the most material-saving method. At the same time, in order to ensure the stability of the profile to be processed during the cutting process, the driving roller presses the profile to be processed up and down at the beginning, and the rotating driving roller The horizontal movement of the profile to be processed can be controlled. When the profile to be processed moves to the processing position, compressed air is added to the filling bag so that the filling bag and the driving roller expand outward as a whole, thereby pressing the profile to be processed. At the same time, during the cutting process, the profile to be processed will vibrate. If a driving roller made of solid material is used to press the profile to be processed, the vibration generated can only be applied to the shaft of the driving roller and the driving member of the driving roller, resulting in a reduced service life of the driving roller. The hollow filling bag can be properly squeezed to consume the energy generated by the vibration, thereby reducing the impact of long-term vibration on parts. Through this setting, a scientific and low-loss cutting processing method is guaranteed, and the cutting process of the profile to be processed is realized in a stable and orderly manner. While reducing the impact of vibration on the equipment, it also reduces the noise caused by vibration.

The translation of the moving seat is controlled by the hydraulic rod 3 to adjust the position of the saw blade horizontally, thereby achieving the effect of the saw blade cutting the profile to be processed at the specified position.

DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figures 1 to 6 As shown, a door and window profile sawing device according to an embodiment of the present invention comprises a processing box 1, a group of rotatable driving rollers 5 are arranged at both ends and inside of the processing box 1, each group comprises two driving rollers 5 symmetrically arranged up and down, a profile 4 to be processed passes through between the two driving rollers 5, both ends of the processing box 1 are provided with processing holes for passing through the profile 4 to be processed, a vertical rotatable saw blade 8 is arranged inside the processing box 1, an adjustable seat 10 of adjustable position is installed on one side of the saw blade 8, and an expandable filling bag 24 is arranged inside the driving roller 5;

[0037] The profile 4 to be processed that needs to be cut is passed through the processing box 1, and the profile 4 to be processed passes through three sets of driving rollers 5 at the same time. The cutting angle of the saw blade 8 is controlled by the adjusting seat 10. Because the two ends of the traditional door and window profiles are both cut at a 45-degree angle, when the two profiles are vertically connected, the cutting angles of the two sections can be completely connected; then the adjusting seat 10 drives the saw blade 8 to sink, and the rotating saw blade 8 first cuts off the profile 4 to be processed, and then the adjusting seat 10 and the saw blade 8 rise, and then sink after adjusting the angle and position, cut the profile 4 to be processed, and cut an equilateral triangle of waste from the entire profile 4 to be processed, and then the profile 4 to be processed at the right end is transported outward by the driving roller 5 at the right end, and the subsequent profile 4 to be processed is transported to the right by the inside of the processing box 1 and the driving roller 5 at the left end. Since the upper and lower surfaces of the profile 4 to be processed are different in shape, in order to ensure that the front and back of the doors and windows after splicing are the same, a method of cutting out equilateral triangles of waste is used, which is also the most material-saving method. At the same time, in order to ensure During the cutting process, the stability of the profile 4 to be processed is ensured by the driving roller 5 which initially presses the profile 4 to be processed up and down. The rotating driving roller 5 can control the horizontal movement of the profile 4 to be processed. When the profile 4 to be processed moves to the processing position, compressed air is added to the filling capsule 24 so that the filling capsule 24 and the driving roller 5 expand outward as a whole, thereby pressing the profile 4 to be processed. At the same time, during the cutting process, the profile 4 to be processed will vibrate. If a driving roller 5 made of solid material is used to press the profile 4 to be processed, the vibration generated can only be applied to the shaft of the driving roller 5 and the driving member of the driving roller 5, resulting in a reduction in the service life of the driving roller 5. The hollow filling capsule 24 can be properly squeezed to consume the energy generated by the vibration, thereby reducing the impact of long-term vibration on parts. Through this arrangement, a scientific and low-loss cutting processing method is guaranteed, and the cutting process of the profile 4 to be processed is realized in a stable and orderly manner. While reducing the impact of vibration on the equipment, the noise caused by vibration is also reduced.

[0038] An isolation plate 7 is provided inside the processing box 1, and the isolation plate 7 is arranged horizontally. A plurality of groups of hydraulic rods 6 are fixedly connected to the bottom of the processing box 1, and each group includes two hydraulic rods 6. A support plate 25 is fixedly connected between the top moving ends of the two hydraulic rods 6 in each group, and the support plate 25 passes through the isolation plate 7.

[0039] During operation, the waste materials that fall after cutting will fall onto the isolation plate 7. A material taking door is provided on one side of the processing box 1 for taking out the waste materials inside. The support plate 25 is lifted upward by multiple sets of hydraulic rods 6 to support the bottom of the profile 4 to be processed, thereby ensuring the horizontal processing state of the profile 4 to be processed and further improving the processing quality.

[0040] The top of the processing box 1 is fixedly connected with an adjustment cabinet 2, the top of the adjustment cabinet 2 is slidably connected with a moving seat 3, a hydraulic rod three is connected between the adjustment cabinet 2 and the moving seat 3, a servo motor 12 is fixedly connected to the bottom of the moving seat 3, a hydraulic rod two 11 is fixedly connected to the bottom of the servo motor 12, the bottom of the hydraulic rod two 11 is fixedly connected to the adjustment seat 10, and a servo motor two for driving the saw blade 8 to rotate is installed in the adjustment seat 10;

[0041] During operation, the servo motor 12 drives the hydraulic rod 2 11 and the adjustment seat 10 to rotate, thereby adjusting the cutting angle of the saw blade 8. The lifting and lowering cutting process of the saw blade 8 is adjusted by extending and shortening the hydraulic rod 2 11. The translation of the moving seat 3 is controlled by the hydraulic rod 3 to horizontally adjust the position of the saw blade 8, thereby achieving the effect of the saw blade 8 cutting the profile 4 to be processed at the specified position.

[0042] A driving motor 14 for driving the driving roller 5 to rotate is installed at one end of the driving roller 5, an inclined electric telescopic rod 9 is fixed to the top of the processing box 1, and support arms 15 for adjusting the position of the driving roller 5 are arranged at both ends of the driving roller 5;

[0043] During operation, the driving motor 14 drives the driving roller 5 to rotate, and the support arm 15 can adjust the distance between the two driving rollers 5 in the same group. In this way, when processing the profiles 4 to be processed of different thicknesses, the distance between the two driving rollers 5 can be adjusted, and the profile 4 to be processed can be firmly clamped in the middle and used for transportation and fixation. When fixing, the inclined electric telescopic rod 9 is extended to press the profile 4 to be processed from the right end above the support plate 25. An elastic pad is fixed to the end of the electric telescopic rod 9 to reduce the rigid contact with the profile 4 to be processed.

[0044] The interior of the driving roller 5 is hollow, and the driving roller 5 includes a central rod 23, and the filling capsule 24 is wrapped around the outer side of the central rod 23. The outer side of the central rod 23 is a protective layer, and the protective layer is made of elastic material. The driving motor 14 is connected to one end of the central rod 23;

[0045] During operation, the material of the protective layer can be hard rubber, which is deformable, but the force required for deformation is large, which is much greater than the force required for the filling capsule 24. As the filling capsule 24 expands, the protective layer is squeezed outward, and the protective layer squeezes the profile 4 to be processed. This setting keeps the expansion amplitude within a controllable range and will not cause excessive expansion to cause the profile 4 to be squeezed and deformed. In addition, the filling capsule 24 is evenly stressed and is not easy to break or leak.

[0046] The other end of the central rod 23 is fixedly connected to a micro air pump 13, the output end of the micro air pump 13 is connected to a three-way solenoid valve, a channel for transmitting air is provided inside the central rod 23, and a plurality of valve valves connected to the filling bag 24 are installed on the surface of the central rod 23;

[0047] During operation, during the rotation of the driving roller 5, the three-way solenoid valve can be remotely controlled. When it is necessary to fix the profile 4 to be processed, the three-way solenoid valve connects the micro air pump 13 and the filling bag 24, and at the same time, the micro air pump 13 is turned on to fill air into the filling bag 24, so that the driving roller 5 expands and presses the profile 4 to be processed. When the profile 4 to be processed needs to be moved, the micro air pump 13 is remotely controlled to be closed, and at the same time, the three-way solenoid valve connects the outside world and the filling bag 24 to relieve part of the internal pressure, thereby reducing the force of the driving roller 5 pressing the profile 4 to be processed, so that the profile 4 to be processed can move normally.

[0048] The support arm 15 is arranged in an arc shape, one end of the support arm 15 is fixedly connected with a rotating shaft 20, the rotating shaft 20 is sleeved on the outside of the center rod 23, and the other end of the support arm 15 is rotatably connected to the processing box 1;

[0049] During operation, the support arm 15 is used to support both sides of the center rod 23. The setting of the rotating shaft 20 allows the center rod 23 to rotate normally while being supported.

[0050] The driving roller 5 has two support arms 15 at one end close to the driving motor 14, a connecting rod 16 is fixedly connected between the two support arms 15, and a motor box 18 is provided on one side of the connecting rod 16 for driving the two connecting rods 16 to rotate synchronously;

[0051] During operation, in order to facilitate the adjustment of the distance between the two driving rollers 5, the stepper motor in the motor box 18 can simultaneously drive the two connecting rods 16 in the same group to rotate in opposite directions at the same time, so that the two driving rollers 5 can be controlled to open or merge at the same time, thereby controlling the distance between the two driving rollers 5, so as to adapt to various widths of the profiles 4 to be processed.

[0052] An integration plate 19 is provided at one end of the linkage rod 16 away from the driving roller 5, and four rotating rods 26 are fixedly connected to the integration plate 19. Four mutually meshing gears 17 are fixedly connected to the ends of the rotating rods 26. Two gears 17 located at the upper and lower ends of the four gears 17 are respectively fixedly connected to two linkage rods 16. A worm gear 21 is fixedly connected to the outer side of one rotating rod 26 located in the middle position of the four rotating rods 26. A worm 22 is fixedly connected to the output end of the motor box 18, and the worm 22 meshes with the worm gear 21.

[0053] During operation, as the stepper motor in the motor box 18 drives the worm 22 to rotate, it drives the worm wheel 21 to rotate. Since the four gears 17 are meshed with each other, when one gear 17 rotates, the two gears 17 at the upper and lower ends will rotate synchronously in the opposite direction. This not only achieves the effect of controlling the distance between the two driving rollers 5, but also the worm wheel 21 and worm 22 have self-locking ability. The gear 17 cannot drive the worm 22 to rotate in the opposite direction. Combined with the self-locking ability of the stepper motor itself, it is ensured that the support arm 15 and the driving roller 5 will not be displaced during the processing.

[0054] A door and window profile sawing process, which is applicable to the door and window profile sawing device described above, and specifically comprises:

[0055] S1: The profile 4 to be processed is passed through the processing box 1, and the profile 4 is passed through three sets of driving rollers 5. The servo motor 12 drives the hydraulic rod 2 11 and the adjustment seat 10 to rotate, thereby adjusting the cutting angle of the saw blade 8. The lifting and lowering cutting process of the saw blade 8 is adjusted by extending and shortening the hydraulic rod 2 11. The translation of the moving seat 3 is controlled by the hydraulic rod 3, thereby adjusting the position of the saw blade 8 horizontally.

[0056] S2: The adjusting seat 10 drives the saw blade 8 to sink, and the rotating saw blade 8 first cuts the profile 4 to be processed, and then the adjusting seat 10 and the saw blade 8 rise, and then sink after adjusting the angle and position, to cut the profile 4 to be processed, and cut an equilateral triangle of waste from the entire profile 4 to be processed;

[0057] S3: The rotating driving roller 5 can control the horizontal movement of the profile 4 to be processed. When the profile 4 to be processed moves to the processing position, compressed air is added to the filling bag 24, so that the filling bag 24 and the driving roller 5 expand outward as a whole, thereby pressing the profile 4 to be processed. When the cutting is completed, the air in the filling bag 24 is released, so that the profile 4 to be processed can be transported normally.

[0058] S4: As the stepper motor in the motor box 18 drives the worm 22 to rotate, the worm wheel 21 is driven to rotate. Since the four gears 17 are meshed with each other, when one gear 17 rotates, the two gears 17 at the upper and lower ends will rotate synchronously in opposite directions.

[0059] S5: The two gears 17 at the upper and lower ends will rotate synchronously in opposite directions and drive the two connecting rods 16 in the same group to rotate in opposite directions at the same time, so that the two driving rollers 5 can be controlled to open or merge at the same time, thereby controlling the distance between the two driving rollers 5 to adapt to various widths of the profiles 4 to be processed.

[0060] During operation, the profile 4 to be processed that needs to be cut passes through the processing box 1, and the profile 4 to be processed passes through three sets of driving rollers 5. The cutting angle of the saw blade 8 is controlled by the adjusting seat 10. Because the two ends of the traditional door and window profiles are both cut at a 45-degree angle, the cutting angles of the two sections can be completely butted when the two profiles are vertically connected; then the adjusting seat 10 drives the saw blade 8 to sink, and the rotating saw blade 8 first cuts off the profile 4 to be processed, and then the adjusting seat 10 and the saw blade 8 rise, and then sink after adjusting the angle and position, cutting the profile 4 to be processed, and cutting an equilateral triangle of waste from the entire profile 4 to be processed, and then the profile 4 to be processed at the right end is transported outward by the driving roller 5 at the right end, and the subsequent profile 4 to be processed is transported to the right by the inside of the processing box 1 and the driving roller 5 at the left end. Since the upper and lower surfaces of the profile 4 to be processed are different in shape, in order to ensure that the front and back of the doors and windows after splicing are the same, a method of cutting out equilateral triangles of waste is used, which is also the most material-saving method, and at the same time, in order to ensure To ensure the stability of the profile 4 to be processed during the cutting process, the driving roller 5 initially presses the profile 4 to be processed up and down, and the rotating driving roller 5 can control the horizontal movement of the profile 4 to be processed. When the profile 4 to be processed moves to the processing position, compressed air is added to the filling capsule 24, so that the filling capsule 24 and the driving roller 5 expand outward as a whole, thereby pressing the profile 4 to be processed. At the same time, during the cutting process, the profile 4 to be processed will vibrate. If a driving roller 5 made of solid material is used to press the profile 4 to be processed, the vibration generated can only be applied to the shaft of the driving roller 5 and the driving member of the driving roller 5, resulting in a reduction in the service life of the driving roller 5. The hollow filling capsule 24 can be properly squeezed to consume the energy generated by the vibration, thereby reducing the impact of long-term vibration on parts. Through this setting, a scientific and low-loss cutting processing method is guaranteed, and the cutting process of the profile 4 to be processed is realized in a stable and orderly manner. While reducing the impact of vibration on the equipment, the noise caused by vibration is also reduced.

[0061] The cut waste will fall onto the isolation plate 7. A material taking door is provided on one side of the processing box 1 to take out the waste inside. The support plate 25 is lifted upward by multiple sets of hydraulic rods 6 to support the bottom of the profile 4 to be processed, thereby ensuring the horizontal processing state of the profile 4 to be processed, and further improving the processing quality.

[0062] The servo motor 12 drives the hydraulic rod 2 11 and the adjustment seat 10 to rotate, thereby adjusting the cutting angle of the saw blade 8. The hydraulic rod 2 11 is extended and shortened to adjust the lifting and cutting process of the saw blade 8. The hydraulic rod 3 controls the translation of the moving seat 3 to adjust the position of the saw blade 8 horizontally, thereby achieving the effect of the saw blade 8 cutting the profile 4 to be processed at the specified position.

[0063] The driving motor 14 drives the driving roller 5 to rotate, and the support arm 15 can adjust the distance between the two driving rollers 5 in the same group. In this way, when processing the profiles 4 to be processed of different thicknesses, the distance between the two driving rollers 5 can be adjusted, and the profiles 4 to be processed can be firmly clamped in the middle and used for transportation and fixing. When fixing, the inclined electric telescopic rod 9 is extended to press the profiles 4 to be processed from the right end above the support plate 25. The end of the electric telescopic rod 9 is fixed with an elastic pad to reduce the rigid contact with the profiles 4 to be processed;

[0064] The material of the protective layer can be hard rubber, which is deformable, but the force required for deformation is large, which is much greater than the force required for the filling capsule 24. As the filling capsule 24 expands, the protective layer is squeezed outward, and the protective layer squeezes the profile 4 to be processed. This arrangement keeps the expansion amplitude within a controllable range, and will not cause the profile 4 to be processed to be squeezed and deformed due to excessive expansion. In addition, the filling capsule 24 is evenly stressed, not easy to break or leak.

[0065] During the rotation of the driving roller 5, the three-way solenoid valve can be remotely controlled. When the profile 4 to be processed needs to be fixed, the three-way solenoid valve connects the micro air pump 13 and the filling capsule 24, and the micro air pump 13 is turned on to fill air into the filling capsule 24, so that the driving roller 5 expands to press the profile 4 to be processed. When the profile 4 to be processed needs to be moved, the micro air pump 13 is remotely controlled to be closed, and the three-way solenoid valve connects the outside world and the filling capsule 24 to relieve part of the internal pressure, thereby reducing the force of the driving roller 5 pressing the profile 4 to be processed, so that the profile 4 to be processed can move normally.

[0066] The support arm 15 is used to support both sides of the center rod 23. The setting of the rotating shaft 20 allows the center rod 23 to rotate normally while being supported;

[0067] In order to facilitate the adjustment of the spacing between the two driving rollers 5, the stepper motor in the motor box 18 can simultaneously drive the two linkage rods 16 in the same group to rotate in opposite directions at the same time, so that the two driving rollers 5 can be controlled to open or merge at the same time, thereby controlling the spacing between the two driving rollers 5, so as to adapt to various widths of the profiles 4 to be processed;

[0068] As the stepper motor in the motor box 18 drives the worm 22 to rotate, it also drives the worm wheel 21 to rotate. Since the four gears 17 are meshed with each other, when one gear 17 rotates, the two gears 17 at the upper and lower ends will rotate synchronously in the opposite direction. This not only achieves the effect of controlling the distance between the two driving rollers 5, but also the worm wheel 21 and worm 22 have self-locking ability. The gear 17 cannot drive the worm 22 to rotate in the opposite direction. Combined with the self-locking ability of the stepper motor itself, it is ensured that the support arm 15 and the driving roller 5 will not be displaced during the processing.
