Profile cutting machine is suitable for construction, hardware, petrochemical, mechanical metallurgy and water and electricity installation industries. Profile cutting machine is a common equipment that can cut metal square flat tubes, square flat steel, I-beams, channel steel, carbon steel, tubes and other materials. Before cutting the profile, you need to mark the cutting line on the profile, then move the profile so that the cutting line is aligned with the cutting knife of the cutting machine, and then use the cutting knife to cut the profile.

[0003] A Chinese patent with application number 201811506807.7 in the related technology proposes a cutting machine, which includes a reflux connecting frame, a support leg, a cutting platform, a driving device and a cutting knife. The reflux connecting frame includes a reflux plate, a front sealing plate and a rear sealing plate. The middle part of the reflux plate is bent downward to form a reflux part with a front opening and a rear opening. The two sides of the reflux plate are bent sequentially to form a connecting part. A vertical pole is provided on the connecting part close to the rear opening. The front sealing plate is provided on the front side of the reflux part to close the front opening, and the rear sealing plate is provided on the rear side of the reflux part to close the rear opening; the support legs are detachably connected to the four corners of the reflux plate through a mounting plate provided at the top of the connecting part; the cutting platform is mounted on the front sealing plate and the rear sealing plate through a sliding device; the driving device is connected to the vertical pole through a rotating shaft, and a travel limit device is provided between the vertical pole and the driving device; the cutting knife is connected to the output end of the driving device.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when cutting the profile, the cutting line must first be manually marked on the surface of the profile, and then the profile is placed on the cutting platform. The cutting platform drives the profile to move towards the cutting knife through a sliding device. In order to achieve precise cutting, it is often necessary to repeatedly adjust the position of the profile by observing the position of the cutting line so that the cutting line on the profile is aligned with the cutting knife. This process consumes a lot of time, affecting the efficiency of batch cutting production of profiles. Summary of the invention

[0005] In order to improve the problem of low efficiency in batch cutting production of profiles, the present application provides a precise cutting machine for oblique sections of profiles.

[0006] The present application provides a profile oblique section precision cutting machine adopts the following technical solution:

[0007] A machine for accurately cutting the oblique cross-section of a profile, comprising a cutting platform, a cutting knife arranged on the cutting platform and a driving device for driving the cutting knife to cut the profile, the cutting platform comprising a marking portion and a cutting portion, a marking device for marking a cutting line is arranged at the marking portion on the cutting platform, the driving device and the cutting knife are both located at the cutting portion, an identification system for identifying the cutting line is arranged at the cutting portion on the cutting platform, and an adjustment device for adjusting the position of the profile is arranged on the cutting platform.

[0008] By adopting the above technical solution, when cutting profiles in batches, it is only necessary to place the profiles on the marking part of the cutting platform, and the marking device automatically marks the cutting line on the profiles. Then the adjustment device transfers the profiles marked with the cutting lines to the cutting part of the cutting platform, and the recognition system automatically recognizes the cutting lines on the profiles, so as to achieve the effect of quickly aligning the cutting lines with the cutting knife. Finally, the driving device is started, and the driving device drives the cutting knife to cut the profiles along the cutting lines. The above structural design of a precise cutting machine for oblique sections of profiles can realize automatic marking of cutting lines and quickly align the cutting lines with the cutting knife, thereby improving the production efficiency of batch cutting of profiles.

[0009] Optionally, the marking device includes a support frame mounted on the cutting platform, a marking head movably arranged on the support frame, and a transfer mechanism located on the support frame and used to drive the marking head to mark the profile, and the support frame is provided with a storage box for providing photosensitive paint to the marking head.

[0010] By adopting the above technical solution, when it is necessary to mark the cutting line on the profile, it is only necessary to first place the profile on the marking part of the cutting platform and start the transfer mechanism. The transfer mechanism drives the marking head to mark the cutting line on the profile according to the cutting size. When the marking head moves, the photosensitive paint in the material storage box is coated on the profile through the marking head to form the cutting line, thereby achieving the purpose of automatic marking of the cutting line. By automatically marking the cutting line on the profile instead of manually marking the cutting line, the production efficiency of batch cutting of the profile can be improved.

[0011] Optionally, a positioning mechanism for positioning the profile is provided on the cutting platform, the positioning mechanism is located on a side of the marking device away from the cutting knife, and the transfer mechanism is electrically connected to the positioning mechanism.

[0012] By adopting the above technical solution, before marking the cutting line on the profile, the profile needs to be positioned on the marking part of the cutting platform. The positioning mechanism identifies the position and size of the profile and transmits the signal of the size and position of the profile to the transfer mechanism. The transfer mechanism calculates and sets the movement trajectory of the marking head according to the size and position of the profile and the cutting size of the profile. Then the transfer mechanism drives the cutting knife to move according to the designed trajectory, and then automatically marks the cutting line on the profile. This process can improve the efficiency of marking the cutting line of the profile, thereby improving the production efficiency of batch cutting of profiles.

[0013] Optionally, a cutting groove is provided on the cutting platform at the cutting portion, and the cutting knife is slidably arranged in the cutting groove. The driving device includes a translation mechanism for driving the cutting knife to slide in the cutting groove and a rotation mechanism for driving the cutting knife to rotate for cutting. The translation mechanism is located on the cutting platform, and the rotation mechanism is located on the translation mechanism.

[0014] By adopting the above technical solution, the adjusting device transfers the profile marked with the cutting line to the cutting part of the cutting platform so that the cutting line is aligned with the cutting groove, and then starts the rotating mechanism, which drives the cutting knife to rotate. At the same time, the translation mechanism is started, which drives the rotating cutting knife to slide in the cutting groove, so that the cutting knife can quickly and stably cut the profile along the cutting line.

[0015] Optionally, a support plate corresponding to the cutting groove is mounted on the cutting platform, and the recognition system includes a light-sensing recognition module located on the support plate and an analysis and processing module electrically connected to the light-sensing recognition module, and the analysis and processing module is electrically connected to the adjustment device.

[0016] By adopting the above technical solution, the support plate sets up the photosensitive recognition module above the cutting groove, and the adjustment device transmits the profile marked with the cutting line to the cutting part of the cutting platform. The analysis and processing module drives the adjustment device to start and stop according to the recognition of the cutting line on the profile by the photosensitive recognition module, thereby automatically adjusting the position of the profile, so that the cutting line on the profile is quickly aligned with the cutting knife, thereby improving the production efficiency of batch cutting of profiles.

[0017] Optionally, the adjusting device includes a clamping mechanism for clamping the profile and a linear drive mechanism for driving the clamping mechanism to move toward / away from the cutting knife, and the linear drive mechanism is electrically connected to the analysis and processing module.

[0018] By adopting the above technical solution, the profile is first placed on the cutting platform, and then the clamp mechanism is used to stably clamp the profile. When the marking device completes marking the cutting line on the profile, the linear drive mechanism is started. The linear drive mechanism drives the profile to move in the direction close to the cutting knife through the clamp mechanism. The analysis and processing module drives the linear drive mechanism to start and stop according to the recognition of the cutting line on the profile by the light sensing recognition module, thereby automatically adjusting the position of the profile, so that the cutting line on the profile is quickly aligned with the cutting knife, thereby improving the production efficiency of batch cutting of profiles.

[0019] Optionally, the clamp mechanism includes a clamping portion and a connecting rod connected to the clamping portion, and one end of the connecting rod away from the clamping portion is connected to the linear drive mechanism.

[0020] By adopting the above technical solution, the linear drive mechanism is connected to the clamping part through a connecting rod. The clamping part is first used to clamp the profile, and then the linear drive mechanism is started. The linear drive mechanism drives the clamping part and the profile to move in a direction close to the cutting knife through the connecting rod, thereby achieving the purpose of quickly driving the profile to a specified position and cutting.

[0021] Optionally, two connecting rods are provided, and both of the two connecting rods are hinged to the clamping portion; and two groups of linear drive mechanisms are provided, and the two groups of linear drive mechanisms are respectively hinged to the two connecting rods.

[0022] By adopting the above technical solution, the two sets of linear drive mechanisms drive the two connecting rods to move respectively, so that the clamping part pushes the profile to move in the direction close to the cutting knife. When the profile needs to be beveled, it is only necessary to control the operating speed / time of the two sets of linear drive mechanisms to adjust the movement stroke of the two connecting rods. Since the two sets of linear drive mechanisms are hinged to the clamping part through the two connecting rods, the clamping part can rotate while sliding horizontally on the cutting platform, thereby adjusting the cutting angle of the cutting knife to the profile, thereby realizing multi-angle bevel cutting of the profile.

[0023] Optionally, the clamping portion includes an abutment plate connected to the connecting rod and clamping plates respectively located at both ends of the abutment plate, the abutment plate and the two clamping plates together form a clamping area for clamping the profile, the clamping plate is slidably arranged on the abutment plate, and a power member for driving the clamping plate to slide is arranged on the abutment plate, and the power member is electrically connected to the transfer mechanism.

[0024] By adopting the above technical solution, the profile is placed in the clamping area, and then the power piece is started, which drives the clamping plate to slide on the abutment plate, so that the profile is quickly clamped between the two clamping plates. The transfer mechanism can calculate the size of the profile along the arrangement direction of the two clamping plates by identifying the distance between the two clamping plates, which further facilitates the transfer mechanism to calculate and set the movement trajectory of the marking head according to the size and position of the profile and the cutting size of the profile. At the same time, the clamping plate is slidably arranged on the abutment plate, so that the clamping part can effectively clamp profiles of different sizes, thereby improving the versatility of the clamping part.

[0025] Optionally, the positioning mechanism includes a connecting frame mounted on the cutting platform, a push plate movably arranged on the connecting frame, and a driving assembly for driving the push plate to push the profile to slide toward the abutment plate, and the driving assembly is located on the connecting frame.

[0026] By adopting the above technical solution, the profile is placed in the clamping area, and then the driving assembly is started. The driving assembly drives the push plate to move on the connecting frame, and the moving push plate pushes the profile to move in the direction close to the abutment plate, so that the end face of the profile away from the push plate abuts against the abutment plate, thereby limiting the position of the profile in the direction perpendicular to the abutment plate. At the same time, the transfer mechanism can calculate the size of the profile in the direction perpendicular to the abutment plate by identifying the distance between the abutment plate and the push plate, which further facilitates the transfer mechanism to calculate and set the movement trajectory of the marking head according to the size and position of the profile and the cutting size of the profile.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. When cutting profiles in batches, you only need to place the profiles on the marking part of the cutting platform. The marking device will automatically mark the cutting line on the profiles. Then the adjustment device will transfer the profiles marked with the cutting line to the cutting part of the cutting platform. The recognition system will automatically recognize the cutting line on the profiles to achieve the effect of quickly aligning the cutting line with the cutting knife. Finally, the driving device will be started, and the driving device will drive the cutting knife to cut the profiles along the cutting line, thereby improving the production efficiency of batch cutting of profiles.

[0029] 2. The positioning mechanism identifies the position and size of the profile and transmits the signal of the size and position of the profile to the transfer mechanism. The transfer mechanism calculates and sets the movement trajectory of the marking head according to the size and position of the profile and the cutting size of the profile. Then the transfer mechanism drives the cutting knife to move according to the designed trajectory, and then automatically marks the cutting line on the profile. This process can improve the efficiency of marking the cutting line of the profile, thereby improving the production efficiency of batch cutting of profiles;

[0030] 3. The two sets of linear drive mechanisms drive the two connecting rods to move respectively, so that the clamping part pushes the profile to move in the direction close to the cutting knife. When the profile needs to be beveled, it is only necessary to control the operating speed / time of the two sets of linear drive mechanisms to adjust the movement stroke of the two connecting rods. Since the two sets of linear drive mechanisms are hinged to the clamping part through the two connecting rods, the clamping part can slide horizontally on the cutting platform and rotate at the same time, thereby adjusting the cutting angle of the cutting knife to the profile, thereby realizing multi-angle bevel cutting of the profile.

[0047] The following is combined with Figure 1-7 This application is described in further detail.

[0048] The present application embodiment discloses a profile oblique section precision cutting machine. Figure 1 and Figure 2 A profile oblique section precision cutting machine includes a cutting platform 2, a cutting knife 1 arranged on the cutting platform 2, and a driving device 3 for driving the cutting knife 1 to cut the profile. The cutting platform 2 includes a marking part 21 and a cutting part 22. The marking part 21 and the cutting part 22 are arranged along the length direction of the cutting platform 2, and the profile is transported along the length direction of the cutting platform 2 on the cutting platform 2. A marking device 4 for marking a cutting line is arranged at the marking part 21 on the cutting platform 2, the driving device 3 and the cutting knife 1 are both located at the cutting part 22, an identification system 5 for identifying a cutting line is arranged at the cutting part 22 on the cutting platform 2, and an adjustment device 6 for adjusting the position of the profile is arranged at the marking part 21 on the cutting platform 2.

[0049] Reference Figure 1 and Figure 2 A cutting groove 9 is provided on the cutting platform 2 at the cutting portion 22. The cutting groove 9 is arranged along the width direction of the cutting platform 2. The cutting knife 1 is inserted into the cutting groove 9, and the cutting knife 1 is arranged to slide along the length direction of the cutting groove 9. The driving device 3 includes a translation mechanism 31 for driving the cutting knife 1 to slide in the cutting groove 9 and a rotation mechanism 32 for driving the cutting knife 1 to rotate and cut. The translation mechanism 31 can be an electric push rod or a lead screw pair.

[0050] In the embodiment of the present application, the translation mechanism 31 is configured as a screw pair, the screw pair is located in the cutting platform 2, the screw pair includes a screw rod, a threaded seat and a motor, the screw rod is connected to the side wall of the cutting platform 2 in a rotational manner along the width direction of the cutting platform 2; the motor is fixedly connected to the cutting platform 2 by screws, and the output end of the motor is coaxially fixedly connected to one end of the screw rod; the threaded seat is threadedly sleeved on the screw rod. The rotating mechanism 32 is also located in the cutting platform 2, the rotating mechanism 32 includes a rotating motor and a connecting plate, the connecting plate stably mounts the rotating motor on the threaded seat, and the cutting knife 1 is rotatably connected to the connecting plate, the cutting knife 1 is disc-shaped, and the output end of the rotating motor is coaxially fixedly connected to the cutting knife 1.

[0051] When the profile needs to be cut, it is only necessary to align the cutting line of the profile with the cutting groove 9, and then start the rotating mechanism 32, which drives the cutting knife 1 to rotate, and at the same time start the translation mechanism 31, which drives the rotating cutting knife 1 to slide in the cutting groove 9, so that the cutting knife 1 can cut the profile quickly and stably along the cutting line.

[0052] In order to improve the cutting quality of the profile, it is often necessary to manually move the profile repeatedly to align the cutting line with the cutting knife 1. This process takes a long time. In order to improve the rapid advancement and positioning of the profile, the present application uses an adjustment device 6 to quickly adjust the position of the profile on the cutting platform 2. Figure 3 and Figure 4 The adjusting device 6 is located at the marking portion 21 of the cutting platform 2. The adjusting device 6 includes a clamping mechanism 61 for clamping the profile and a linear driving mechanism 62 for driving the clamping mechanism 61 to move toward / away from the cutting knife 1. The clamping mechanism 61 stably clamps the profile, and the linear driving mechanism 62 drives the profile to move toward the cutting knife 1 through the clamping mechanism 61, thereby quickly advancing the profile for positioning.

[0053] Reference Figure 4 and Figure 5 The clamp mechanism 61 includes a clamping portion 611 and a connecting rod 612 connected to the clamping portion 611. The clamping portion 611 includes an abutting plate 6111 connected to the connecting rod 612 and clamping plates 6112 respectively located at both ends of the abutting plate 6111. The abutting plate 6111 is arranged along the width direction of the cutting platform 2. The two clamping plates 6112 are vertically arranged on the end surface of the abutting plate 6111 close to the cutting blade 1. The abutting plate 6111 and the two clamping plates 6112 together form a clamping area for clamping the profile. In order to achieve rapid clamping of the profile, in the embodiment of the present application, one clamping plate 6112 is vertically fixed to the abutting plate 6111, and the other clamping plate 6112 is slidably connected to the abutting plate 6111 along the length direction of the abutting plate 6111. A power piece 11 for driving the clamping plate 6112 to slide is provided at one end of the abutment plate 6111. The power piece 11 is configured as an electric push rod. The electric push rod pushes one clamping plate 6112 to move toward / away from the other clamping plate 6112, so that the profile located in the clamping area is stably clamped between the two clamping plates 6112.

[0054] Reference Figure 4 and Figure 5The linear drive mechanism 62 and the connecting rod 612 are both located on the side of the abutment plate 6111 away from the cutting knife 1. The linear drive mechanism 62 can be an electric push rod drive assembly 73 or a cylinder drive assembly 73. In the embodiment of the present application, the linear drive mechanism 62 is configured as a cylinder drive assembly 73. The cylinder drive assembly 73 includes a cylinder and a mounting frame. The cylinder body of the cylinder is installed on the cutting platform 2 through the mounting frame. The output end of the cylinder is hinged to one end of the connecting rod 612, and the other end of the connecting rod 612 is hinged to the abutment plate 6111. The hinged rods at the hinged ends of the connecting rod 612 are parallel to each other and are both perpendicular to the cutting platform 2.

[0055] To achieve multi-angle bevel cutting of profiles, refer to Figure 4 and Figure 5 There are two connecting rods 612 , both of which are hinged to the abutment plate 6111 of the clamping portion 611 . There are also two groups of linear drive mechanisms 62 , and the cylinders of the two groups of linear drive mechanisms 62 are hinged to the two connecting rods 612 , respectively.

[0056] The two sets of linear drive mechanisms 62 drive the two connecting rods 612 to move respectively, so that the clamping part 611 pushes the profile to move in the direction close to the cutting knife 1. When the profile needs to be beveled, it is only necessary to control the operating speed / time of the two sets of linear drive mechanisms 62 to adjust the movement stroke of the two connecting rods 612. Since the two sets of linear drive mechanisms 62 are hinged to the clamping part 611 through the two connecting rods 612, the clamping part 611 can slide linearly on the cutting platform 2 while also rotating, thereby adjusting the cutting angle of the cutting knife 1 to the profile, thereby realizing multi-angle bevel cutting of the profile.

[0057] Reference Figure 4 and Figure 5 The cutting platform 2 is provided with a positioning mechanism 7 for positioning the profile, and the positioning mechanism 7 is located at one side of the cutting platform 2, and the positioning mechanism 7 is located at the marking portion 21 of the cutting platform 2. The positioning mechanism 7 includes a connecting frame 71 mounted on the cutting platform 2, a push plate 72 movably arranged on the connecting frame 71, and a driving assembly 73 for driving the push plate 72 to push the profile to slide toward the direction close to the abutting plate 6111.

[0058] Reference Figure 4 and Figure 5The driving assembly 73 includes an electric cylinder and a servo motor. The cylinder body of the electric cylinder is fixed to the connecting frame 71 by screws. The piston rod of the electric cylinder is telescopically arranged along the length direction of the cutting platform 2. The servo motor is fixed to the piston rod of the electric cylinder through the motor seat, and the output shaft of the servo motor is arranged perpendicular to the cutting platform 2. One end of the push plate 72 is hinged on the motor seat and fixed to the output end of the servo motor. The other end of the push plate 72 rotates around the motor seat toward / away from the abutment plate 6111 under the drive of the servo motor. The rotating push plate 72 can push the profile to move toward the abutment plate 6111 and abut against the abutment plate 6111, thereby limiting the position of the profile along the length direction of the cutting platform 2. At the same time, the interaction of the two clamping plates 6112 realizes the position limitation of the profile along the width direction of the cutting platform 2.

[0059] After the profile is positioned and clamped, the marking device 4 marks the cutting line on the profile, referring to Figure 3 and Figure 6 The marking device 4 is located between the positioning mechanism 7 and the cutting knife 1. The marking device 4 includes a support frame 41 mounted on the cutting platform 2, a marking head 42 movably arranged on the support frame 41, and a transfer mechanism 43 located on the support frame 41 and used to drive the marking head 42 to mark the profile. The transfer mechanism 43 includes a first translation component 431, a second translation component 432 and a lifting component 433. The first translation component 431 and the second translation component 432 are both configured as a lead screw pair. The lifting component 433 includes a micro cylinder and a mounting seat. The first translation component 431 is installed on the support frame 41. The first translation component 431 can drive the marking head 42, the second translation component 432 and the lifting component 433 to slide along the width direction of the cutting platform 2; the second translation component 432 can drive the marking head 42 and the lifting component 433 to slide along the length direction of the cutting platform 2; the lifting component 433 can drive the marking head 42 to lift and slide along the direction perpendicular to the table surface of the cutting platform 2. The positioning mechanism 7 and the power member 11 are both electrically connected to the transfer mechanism 43 .

[0060] Reference Figure 3 and Figure 6 A material storage box 8 for providing photosensitive paint to the marking head 42 is provided on the support frame 41. The material storage box 8 is connected with the marking head 42 through a material guide pipe. The photosensitive paint in the material storage box 8 flows to the marking head 42 through the material guide pipe. The marking head 42 can automatically mark the cutting line of the profile under the drive of the transfer mechanism 43.

[0061] When marking the cutting line on the profile, the profile is first placed in the clamping area, and then the driving assembly 73 is started. The driving assembly 73 pushes the profile to move in the direction close to the abutment plate 6111 through the push plate 72, so that the end face of the profile away from the push plate 72 abuts against the abutment plate 6111, thereby limiting the position of the profile in the direction perpendicular to the abutment plate 6111. The transfer mechanism 43 can calculate the size of the profile in the direction perpendicular to the abutment plate 6111 by identifying the distance between the abutment plate 6111 and the push plate 72. Then, the power member 11 is started, and the power member 11 drives the clamping plate 6112 to slide on the abutment plate 6111, so that the profile is quickly clamped between the two clamping plates 6112. The transfer mechanism 43 can calculate the size of the profile in the layout direction of the two clamping plates 6112 by identifying the distance between the two clamping plates 6112. At this time, the transfer mechanism 43 calculates and sets the movement trajectory of the marking head 42 according to the size and position of the profile and the cutting size of the profile. Finally, the transfer mechanism 43 is started, and the transfer mechanism 43 drives the marking head 42 to mark the cutting line on the profile. When the marking head 42 moves, the photosensitive paint in the storage box 8 is coated on the profile through the marking head 42 to form a cutting line, thereby achieving the purpose of automatically marking the cutting line.

[0062] After the cutting line of the profile is marked, in order to quickly align the cutting line with the cutting groove 9, refer to Figure 4 and Figure 7 A support plate 10 corresponding to the cutting groove 9 is mounted on the cutting platform 2, and the recognition system 5 includes a light-sensing recognition module 51 located on the support plate 10 and an analysis and processing module 52 electrically connected to the light-sensing recognition module 51. The light-sensing recognition module 51 is composed of a plurality of light-sensing detection heads, which are arranged along the length direction of the cutting groove 9, and the connection line formed by the plurality of light-sensing detection heads is aligned with the notch of the cutting groove 9. The light-sensing detection heads can recognize and detect the light-sensitive coating on the profile, and the analysis and processing module 52 can detect the length of the cutting line on the profile surface through the light-sensing recognition module 51, and the analysis and processing module 52 is electrically connected to the linear drive mechanism 62.

[0063] When driving the cutting line of the profile to align with the cutting groove 9, the two linear drive mechanisms 62 are first started. The two sets of linear drive mechanisms 62 drive the two connecting rods 612 to move respectively, so that the clamping part 611 pushes the profile to move in the direction close to the cutting knife 1. One end of the cutting line on the profile first moves to the cutting groove 9 and is detected by the light-sensing recognition module 51. At this time, the analysis and processing module 52 drives one linear drive mechanism 62 to stop working, and the other linear drive mechanism 62 continues to work, driving the profile to rotate on the cutting platform 2, so that the other end of the cutting line on the profile also moves to the cutting groove 9 and is detected by the light-sensing recognition module 51. Only when the light-sensing recognition module 51 detects that the length of the cutting line on the surface of the profile is consistent with the length of the cutting line marked by the marking head 42, the analysis and processing module 52 drives both linear drive mechanisms 62 to stop working, and the cutting line on the profile is aligned with the cutting groove 9.

[0064] The implementation principle of a machine for precisely cutting the oblique cross-section of a profile in an embodiment of the present application is as follows: first, place the profile in the clamping area, start the drive assembly 73 and the power piece 11 in sequence, and the profile is stably clamped and positioned on the cutting platform 2 under the drive of the drive assembly 73 and the power piece 11. At the same time, the transfer mechanism 43 can identify the position and size of the profile, and the transfer mechanism 43 calculates and sets the movement trajectory of the marking head 42 according to the size and position of the profile and the cutting size of the profile.

[0065] Then the transfer mechanism 43 is started, and the transfer mechanism 43 drives the marking head 42 to mark the cutting line on the profile. When the marking head 42 moves, the photosensitive paint in the storage box 8 is coated on the profile through the marking head 42 to form a cutting line, thereby achieving the purpose of automatically marking the cutting line.

[0066] After completing the marking of the cutting line of the profile, start the two linear drive mechanisms 62. The analysis and processing module 52 controls the start and stop of the two linear drive mechanisms 62 by detecting the length of the cutting line on the surface of the profile through the photosensitive recognition module 51. When the photosensitive recognition module 51 detects that the length of the cutting line on the surface of the profile is consistent with the length of the cutting line marked by the marking head 42, the analysis and processing module 52 drives the two linear drive mechanisms 62 to stop working. At this time, the cutting line on the profile is aligned with the cutting groove 9.

[0067] Finally, the driving device 3 is started, and the driving device 3 drives the cutting knife 1 to cut the profile quickly and stably along the cutting line.

[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
