[0025] like Figure 1-7 As shown, a front scoring knife holder that can move forward and backward is installed on the front plate 351, and the front scoring knife holder drives the front scoring knife 31 to move forward and backward, and at the same time, the up and down movement of the front plate 351 drives the up and down movement of the front scoring knife 31. The left and right movement of the milling frame 33 drives the left and right movement of the front plate 351, and then drives the left and right movement of the front scoring knife 31. Through the movement of the milling frame 33, the front plate 351 and the front scoring knife holder, the front scoring knife 31 can respectively achieve three-axis movement in the horizontal, longitudinal and up and down directions.

After the milling is completed, the rear scoring cutter 32 is used to score the required position of the rear end surface of the profile, thereby determining the subsequent processing position. In this embodiment, the left end surface of the second milling cutter seat 342 is provided with another rear scoring cutter 32 that can move up and down and can move forward and backward.

[0026] like Figure 1-8As shown, a positioning device 6 is provided between the milling device 3 and the sawing device 4.

In this embodiment, the transverse rollers 61 include three, two of which are arranged in parallel on the left and right sides and located at the lower side of the profile channel, and one is located at the upper side of the profile channel. While fixing the upper and lower positions of the profile, the two transverse rollers 61 support and prevent the profile from tilting, further ensuring the stability of the profile in the profile channel. At the same time, the transverse rollers 61 and the longitudinal rollers can rotate along the axis. When the profile needs to move, the fixing block is loosened to reduce the friction of the profile when it moves horizontally, facilitating the movement of the profile.

[0027] like Figure 1-7As shown, the sawing device 4 includes a saw blade 41 that can move up and down to cut the profile on the workbench 42, and the saw blade 41 can rotate along the vertical axis to change the cutting direction. A sliding seat 43 is provided at the front end of the workbench 42, and a moving seat 44 that can move up and down is installed on the sliding seat 43. A saw blade seat 45 is installed at the rear end of the moving seat 44, and the saw blade seat 45 is installed with the saw blade 41 and a motor that drives the saw blade 41 to rotate. The saw blade seat 45 and the moving seat 44 are rotatably connected through a rotating shaft. In this embodiment, a gear box is installed at the upper end of the moving seat, and a gear is mounted on the rotating shaft. The gear in the gear box is meshed with the gear on the rotating shaft for transmission. The input gear in the gear box is driven to rotate by a servo motor, and then the rotating shaft is driven to rotate in the connecting hole at the rear end of the moving seat 44, thereby changing the angle of the saw blade seat 45. In other embodiments, a gear rack meshing method can be adopted, through the meshing of the rack and the rotating shaft gear, the gear is driven to move by a cylinder or an electric push rod, and then the gear rack meshing drives the rotating shaft gear to rotate, and then the rotating shaft rotates to change the angle of the saw blade seat 45. After the angle of the saw blade seat 45 is changed, the cutting angle of the saw blade 41 changes. When the saw blade 41 moves downward for cutting, it can cut the end faces of the profiles at different angles, which increases the applicability of the equipment and improves production efficiency. A cutting groove 46 for avoiding the saw blade 41 is provided on the workbench 42, and a clamping device 5 for clamping and positioning the profile is provided on the workbench 42. Two fixed pulley sets 48 are provided at the top of the sliding seat 43, and the two fixed pulley seats are arranged in parallel on the left and right, respectively located on the left and right parts of the sliding seat 43. A counterweight block 47 that can slide up and down is installed on the front end surface of the sliding seat 43. A vertically arranged guide rail is installed on the front end surface of the sliding seat 43, and the guide rail includes two rails, which are respectively located on the left and right parts of the counterweight block 47. The counterweight 47 is driven by a driving device to slide up and down along the guide rail. The fixed pulley group 48 includes two fixed pulleys, and the two fixed pulleys are respectively at the front end and the rear end of the sliding seat 43, and the two fixed pulleys are located above the moving seat 44 and above the counterweight 47. The moving seat 44 and the counterweight 47 are linked by two connecting ropes, and each connecting rope passes around two fixed pulleys of a set of fixed pulley groups 48, and each connecting rope changes direction twice through the fixed pulley. The two groups of fixed pulley groups 48 arranged on the left and right ensure that the force on the left and right sides is uniform when the saw blade 41 is pulled, and the stability of the saw blade 41 when it moves downward is ensured, and the vertical downward movement of the saw blade 41 is ensured. By adopting the method of two fixed pulleys, the force direction is changed twice, and the position of the saw blade 41 is changed up and down by moving the position of the counterweight 47. At the same time, compared with only one fixed pulley and the inclined traction of the connecting rope, the connecting rope in this embodiment is pulled vertically, so that the connecting rope is evenly stressed, damage to the connecting rope is avoided, the sliding is smoother, and the power output is reduced. While ensuring the position accuracy of the saw blade 41, the service life of the sawing device 4 is guaranteed, and the economic benefits are improved.

[0028] like Figure 1-7As shown, the clamping device 5 includes a baffle plate installed on the workbench 42 and a clamping frame 52 installed on the frame 1. The clamping frame 52 is provided with a clamping seat 53 that can move left and right. The clamping seat 53 is provided with a clamping block 51 that is inclined and can move in an inclined direction. The end face of the clamping block 51 is parallel to the front and rear end faces of the profile, and the bottom end face of the clamping face fits with the workbench 42. When the clamping block 51 moves forward at an angle, the front end face of the clamping block 51 fits the rear end face of the profile, and the baffle plate fits the front end face of the profile. The clamping block 51 and the baffle plate play a clamping role together, ensuring the stability of the profile during sawing and the quality of the processed product. When the clamping block 51 moves backward at an angle, the clamping is released, and the profile can continue to move horizontally left and right in the profile channel.

[0029] like Figure 1-7 As shown, when the loading clamping device 21 moves the milled profile to the left into the sawing device 4, the position of the profile is determined by the marking on the profile, and then the clamping device 5 clamps the position, and the profile is positioned by the clamping device 5 and the positioning device 6. According to the needs of the profile, the saw blade seat 45 is driven to rotate by the driving device, and the relative angle between the saw blade 41 and the profile changes. After rotating to the required angle, the counterweight block 47 moves upward, the connecting rope pulls the movable seat 44 downward through the fixed pulley, and the saw blade 41 cuts the profile downward. After the cutting is completed, the counterweight block 47 moves downward, the connecting rope pulls the movable seat 44 upward through the fixed pulley, and then drives the saw blade 41 to move upward. Since the saw blade 41 can flexibly change the angle, the end faces of the profile at different angles can be processed, thereby increasing the adaptability of the equipment.

[0030] like Figure 1 , 2 As shown, the discharging device 7 includes a plurality of longitudinal transmission belts that can be arranged on the frame 1, and the plurality of transmission belts can support a plurality of profiles. Different numbers of transmission belts can support profiles of different lengths, thereby improving the adaptability of the profiles. When the profile processing is completed, the processed profile moves to the left and then falls onto the discharging device 7. As the transmission belt drives the processed profile to move backward, a plurality of processed profiles can be stored and transported in the discharging device 7, thereby improving the processing efficiency.
