Description

Technical Field

[0001] The invention relates to the technical field of door and window components, in particular to a customized processing device for door and window components. Background Art

[0002] As is known to all, windows, in architecture, refer to openings built on walls or roofs to allow light or air to enter a room. Modern windows are composed of three parts: window frames, glass, and movable components (hinges, handles, pulleys, etc.). The window frame is responsible for supporting the main structure of the window, and the transparent part is attached to the window frame. The movable components are mainly made of metal materials. When manufacturing doors and windows, it is necessary to cut the aluminum alloy profiles of doors and windows. When cutting the aluminum alloy profiles of doors and windows, most of them are cut into a sharp shape with a 45-degree angle at the end to facilitate the subsequent assembly and transportation of the aluminum alloy profiles.

[0003] For example, the invention patent with publication number CN112091668B, publication date November 5, 2021, and name "A Door and Window Profile Cutting Equipment for Door and Window Production", discloses a door and window profile cutting equipment for door and window production, including a base, a cutting device and a positioning device, the cutting device is arranged on the base, the positioning device includes a first bracket, a first positioning wheel, a second bracket, a second positioning wheel, a third bracket, a third positioning wheel, a fourth bracket, a fourth positioning wheel, a first lifting device and a second lifting device, the first bracket and the first lifting device are arranged on one side of the base, the third bracket and the second lifting device are arranged on the other side of the base, the second bracket is installed on the first lifting device, the fourth bracket is installed on the second lifting device, the first positioning wheel is installed on the first bracket, the second positioning wheel is installed on the second bracket, the third positioning wheel is installed on the third bracket, the fourth positioning wheel is installed on the fourth bracket, the second positioning wheel is arranged above the first positioning wheel, and the fourth positioning wheel is located above the third positioning wheel. Compared with the prior art, the present invention can achieve stable positioning of the profile.

[0004] In the prior art (such as the above-mentioned patent), when cutting door and window profiles, most of them can only be cut horizontally. When the ends of the door and window profiles are cut into a 45-degree angle, they need to be manually cut again using a cutting tool, resulting in a waste of the door and window profiles. Even when the 45-degree angle is cut directly by the cutting tool, the rotation angle of the cutting knife needs to be adjusted by a motor, making the cutting of the door and window profiles complicated. Summary of the invention

[0005] The object of the present invention is to provide a door and window component custom processing device to solve the above-mentioned problems in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A door and window component custom processing device includes a cutting knife, the top end of the cutting knife is connected to a rotating roller, and the rotating roller is used to change the cutting angle of the cutting knife, and also includes:

[0008] The driven rotating unit includes a sleeve and a positioning rod. A serrated annular groove is provided on the outer wall of the rotating roller. The sleeve is sleeved on the outer side of the rotating roller. A positioning rod is provided on the inner wall of the sleeve. The positioning rod is installed in the serrated annular groove in a sliding manner. The sleeve is driven to change the cutting angle of the cutting knife through the rotating roller.

[0009] As mentioned above, the driven rotating unit also includes a supporting plate and an auxiliary frame. The supporting plate is arranged on the frame of the door and window component custom processing device. An auxiliary frame is arranged on the top of the supporting plate. A linear reciprocating motion mechanism is arranged on the auxiliary frame. A rotating roller is installed on the output end of the linear reciprocating motion mechanism in a rotationally matched manner through a propulsion shaft. The sleeve is fixedly installed on the side wall of the auxiliary frame.

[0010] As mentioned above, the angle between the cutting knife arranged at the bottom end of the rotating roller and the supporting plate is 45 degrees or 135 degrees.

[0011] As mentioned above, the serrated annular groove is an annular groove formed by connecting four identical arc surface spiral grooves and straight grooves to each other. The arc surface spiral groove is an arc groove extending simultaneously along the circumferential direction and the axial direction on the outer wall surface of the rotating roller. The straight groove is arranged parallel to the axis of the rotating roller. Any two adjacent arc surface spiral grooves are connected by straight grooves parallel to the axis of the rotating roller. Both ends of the straight groove exceed the two ends of the two arc surface spiral grooves. An arc surface protrusion is arranged at the intersection position of the straight groove and the bottom end of the arc surface spiral groove.

[0012] As mentioned above, a groove is provided on the inner wall of the sleeve, the positioning round rod is installed in the groove in a sliding fit manner, and the positioning round rod and the inner wall of the groove are connected by a tightening spring.

[0013] As mentioned above, a clamping ring plate is arranged on the outer side of the bottom end of the rotating roller, and four sleeve rods are evenly installed on the bottom end of the clamping ring plate along its circumferential direction, and clamping rods are installed in the four sleeve rods by means of sliding fit, and the top ends of the four clamping rods and the inner walls of the sleeve rods are connected by auxiliary springs, and clamping blocks are arranged on the bottom ends of the four clamping rods, and anti-slip pads are arranged on the bottom ends of the four clamping blocks.

[0017] As mentioned above, a baffle is provided at the end of the inclined discharge plate away from the collecting barrel.

[0018] The beneficial effects of the present invention are as follows: the door and window profiles are cut by a cutting knife, the cutting knife directly cuts the door and window profiles at an angle of 45 degrees, and when continuing to cut the door and window profiles, it is necessary to change the cutting angle of the cutting knife on the door and window profiles. In the process of the rotating roller sliding in the sleeve, since the positioning round rod is slidably arranged in the serrated annular groove, when the rotating roller slides in the sleeve, the rotating roller rotates 90 degrees to change the cutting angle of the cutting knife, so that the two ends of the door and window profiles are cut into an angle of 45 degrees, so that the door and window profiles as a whole are isosceles trapezoidal.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 13As shown, an embodiment of the present invention provides a customized processing device for door and window components, including a cutting knife 1, a rotating roller 11 is connected to the top end of the cutting knife 1, and the rotating roller 11 is used to change the cutting angle of the cutting knife 1. It also includes a driven rotating unit 2, which includes a sleeve 21 and a positioning rod 22. A serrated annular groove 12 is opened on the outer wall of the rotating roller 11, and the sleeve 21 is sleeved on the outer side of the rotating roller 11. A positioning rod 22 is arranged on the inner wall of the sleeve 21, and the positioning rod 22 is installed in the serrated annular groove 12 in a sliding fit manner, and the sleeve 21 is driven to change the cutting angle of the cutting knife 1 through the rotating roller 11.

[0037] Specifically, the door and window profile is conveyed to the bottom end of the cutting knife 1 by a conveying device or manually, and the rotating roller 11 is driven to slide toward its bottom end in the sleeve 21. During the downward sliding process of the rotating roller 11 in the sleeve 21, the positioning rod 22 slides along the trajectory of the serrated annular groove 12. Since the position of the positioning rod 22 remains unchanged, the serrated annular groove 12 on the rotating roller 11 rotates under the tight action of the positioning rod 22, so that the rotating roller 11 rotates to a suitable cutting angle (that is, the angle between the cutting knife 1 and the supporting plate 23 is 45 degrees, and the cutting knife 1 cuts the end of the door and window profile into 45 degrees. The reason for this is that the most common end angle of the door and window profile in the industry is 45 degrees. However, this angle is determined by the shape of the serrated annular groove 12 during processing. Obviously, for customized products, different serrated annular grooves 12 can be obtained by replacing a rotating roller 11. The end angle of the cutting knife 1 is set to the end angle of the cutting knife 1, so that the cutting knife 1 can stably cut the door and window profile. After the cutting knife 1 completes the cutting operation on the door and window profile, the rotating roller 11 is driven to slide to the initial position toward its top end in the sleeve 21 (that is, the cutting knife 1 moves to the topmost cutting position). In the process of the rotating roller 11 sliding to the initial position toward its top end in the sleeve 21, the rotating roller 11 will not rotate in the sleeve 21, and the door and window profile will continue to be conveyed, and the rotating roller 11 is driven to slide to its bottom end in the sleeve 21. After the rotating roller 11 moves in the sleeve 21, the rotating roller 11 drives the cutting knife 1 to rotate to a suitable angle (that is, the angle between the cutting knife 1 and the supporting plate 23 is 135 degrees, and the cutting knife 1 cuts the end of the door and window profile into 45 degrees). By repeating the above operation, the door and window profile can be continuously cut, and the door and window profile can be cut into an isosceles trapezoidal shape, which is convenient for the subsequent assembly and installation of the door and window profile.

[0038] Furthermore, the driven rotating unit 2 also includes a support plate 23 and an auxiliary frame 24. The support plate 23 is arranged on the frame of the door and window component custom processing device. The auxiliary frame 24 is arranged on the top of the support plate 23. The auxiliary frame 24 is provided with a linear reciprocating motion mechanism 25. The output end of the linear reciprocating motion mechanism 25 is installed with a rotating roller 11 through a propulsion shaft 26 in a rotationally matched manner. The sleeve 21 is fixedly installed on the side wall of the auxiliary frame 24. Specifically, when the rotating roller 11 slides in the sleeve 21, the position of the sleeve 21 needs to remain unchanged, so that the rotating roller 11 will not affect the position of the positioning rod 22 when performing reciprocating motion. The linear reciprocating motion mechanism 25 provides power for the rotating roller 11 to slide in the sleeve 21, and is preferably a cylinder or an electric push rod. Other linear reciprocating motion mechanisms 25 may also be used.

[0039] Furthermore, the angle between the cutting knife 1 arranged at the bottom end of the rotating roller 11 and the support plate 23 is 45 degrees or 135 degrees. In essence, the angle between the cutting knife 1 and the conveying track of the long door and window profile is 45 degrees or 135 degrees. Specifically, when the door and window profile is being conveyed, the door and window profile is conveyed parallel to the support plate 23. When the door and window profile is conveyed to the bottom end of the cutting knife 1, the angle between the cutting knife 1 and the door and window profile needs to be 45 degrees or 135 degrees. In this way, the cutting angle of the cutting knife 1 on the door and window profile is sharp at 45 degrees, and the cutting knife 1 needs to change the cutting angle when cutting the door and window profile next time, otherwise the door and window profile will be cut into a parallelogram shape, which needs to be re-cut later, which is more troublesome and causes waste of materials.

[0040] Preferably, two symmetrical plates 13 are installed at the bottom of the rotating roller 11, and the angle between the plates 13 and the support plate 23 is 45 degrees or 135 degrees. A cutting motor 14 is installed on the plate 13 located on one side of the bottom of the rotating roller 11, and a block 15 is installed at the output end of the cutting motor 14. A first annular plate 16 is arranged on the block 15. A driven disc 17 is installed in a rotationally matched manner on the plate 13 located on the other side of the bottom of the rotating roller 11. A square groove 18 is opened at the center of the driven disc 17. A plug rod 19 is installed in the square groove 18 in a slidingly matched manner, and the plug rod 19 and the block 15 plug-in matching, the part of the plug rod 19 located inside the square groove 18 and close to the side of the block 15 is installed with a reset plate 110, the reset plate 110 and the side wall of the square groove 18 away from the block 15 are connected by a reset spring 111, the part of the plug rod 19 close to the block 15 is installed with a second annular plate 112, the first annular plate 16 and the side wall of the second annular plate 112 close to each other are both installed with anti-slip rings 113, the block 15 is sleeved with a cutting blade 116, and the two anti-slip rings 113 are pressed against the outer wall of the cutting blade 116, and the end of the plug rod 19 away from the block 15 The threaded rod 117 is installed on the outer wall of the driven disc 17. Specifically, when the cutting disc 116 needs to be replaced, the operator uses a tool to screw the threaded rod 117 out of the driven disc 17, and then pulls the insertion rod 19 out of the block 15. At this time, the reset spring 111 is in a compressed state, and the cutting disc 116 is taken out from the block 15, and then the cutting disc 116 to be replaced is placed on the block 15, so that the cutting disc 116 is pressed against the first annular plate 16, and then the tension on the insertion rod 19 is released. Under the rebound effect of the reset spring 111, the insertion rod 19 is reinserted into the block 15. , so that the insertion rod 19 and the block 15 are plugged into each other, and at this time, the anti-slip ring 113 on the first annular plate 16 and the second annular plate 112 is pressed against the outer wall of the cutting blade 116 to prevent the cutting blade 116 from swinging during rotation. At this time, tighten the positioning threaded rod 117, fix the insertion rod 19 on the driven disc 17, and replace the cutting blade 116. Since the cutting blade 116 is installed on the block 15, when the cutting motor 14 drives the block 15 to rotate, the block 15 drives the cutting blade 116 to cut the door and window profiles, and the cutting blade 116 can be conveniently replaced.

[0041] Furthermore, the serrated annular groove 12 is an annular groove formed by connecting four identical cambered spiral grooves 121 and straight grooves 122 to each other. The cambered spiral groove 121 is an arc groove extending simultaneously along the circumferential direction and the axial direction on the outer wall surface of the rotating roller 11, that is, the starting and ending positions of the cambered spiral groove 121 are at different positions in the circumferential direction and the axial direction of the rotating roller 11, and the straight groove 122 is arranged parallel to the axis of the rotating roller 11. Any two adjacent cambered spiral grooves 121 are connected by the straight grooves 122 parallel to the axis of the rotating roller 11, and both ends of the straight grooves 122 exceed the two ends of the two cambered spiral grooves 121. As mentioned above, the adjacent ends of the adjacent cambered spiral grooves 121 are at different positions in the axial direction, so that the straight grooves 122 can be connected The two ends are connected, and an arc surface protrusion 123 is arranged at the intersection position between the straight groove 122 and the bottom end of the arc surface spiral groove 121 (the ends of the two arc surface spiral grooves 121, one is located at the upper end in the axial direction, that is, the vertical direction, and the other is located at the bottom end in the vertical direction). The arc surface protrusion 123 makes the straight groove 122 higher at the three-way intersection where the straight groove 122 and the bottom end of the arc surface spiral groove 121 are connected, while the common area of ​​the straight groove 122 and the arc surface spiral groove 121 and the area of ​​the arc surface spiral groove 121 are lower. Specifically, (1) when the linear reciprocating motion mechanism 25 drives the rotating roller 11 to slide toward the bottom end side in the sleeve 21, that is, the cutting knife 1 moves from the initial position (that is, the positioning rod 22 is located at the bottom end position of the straight groove 122 of the rotating roller 11) to the bottom end side of the straight groove 122 of the rotating roller 11. When the rotating roller 11 slides toward the bottom side thereof in the sleeve 21, the positioning rod 22 slides along the track of the serrated annular groove 12 on the rotating roller 11. When the positioning rod 22 slides from the straight groove 122 at the bottom end of the rotating roller 11 to the arc surface spiral groove 121, since the positioning rod 22 still tends to slide along the track of the straight groove 122, when the positioning rod 22 slides to the connection position between the straight groove 122 and the arc surface spiral groove 121, with the assistance of the arc surface protrusion 123 (due to the protrusion of the arc surface protrusion 123, there is a certain height difference between the arc surface protrusion 123 and the straight groove 122 at the bottom end of the rotating roller 11), the positioning rod 22 is pressed against the arc surface protrusion 123, and the arc surface protrusion 123 is pressed against the arc surface protrusion 123. 22 will not slide from the bottom end of the straight groove 122 located at the rotating roller 11 to the top end thereof), so that the positioning round rod 22 slides from the straight groove 122 to the arc surface spiral groove 121, and the positioning round rod 22 continues to slide from the arc surface spiral groove 121 to another straight groove 122 located at the top end of the rotating roller 11. During the sliding process in the arc surface spiral groove 121, since the position of the positioning round rod 22 remains unchanged, the rotating roller 11 rotates 90 degrees during the sliding process toward the bottom end of the sleeve 21. When the positioning round rod 22 slides into another straight groove 122, the cutting knife 1 at the bottom end of the rotating roller 11 is pressed against the door and window profile. When the positioning round rod 22 slides in the straight groove 122 located at the top end of the rotating roller 11, the cutting knife 1 performs a cutting operation on the door and window profile.(2) After the cutting knife 1 has finished cutting the door and window profile, the linear reciprocating motion mechanism 25 drives the rotating roller 11 to slide toward the top side in the sleeve 21. During the sliding process of the rotating roller 11 toward the top side in the sleeve 21, the positioning rod 22 slides from the straight groove 122 at the top of the rotating roller 11 through the arc-surface protrusion 123 to the straight groove 122 at the bottom of the rotating roller 11, so that when the rotating roller 11 slides toward the top side in the sleeve 21, the rotating roller 11 will not rotate, so that the cutting blade 116 will not rotate during the process of moving to the initial position (when the positioning rod 22 is located in the straight groove 122 at the bottom of the rotating roller 11) after the cutting is completed. ;

[0042] In this embodiment, the movement stroke of the rotating roller 11 corresponding to the cutting operation stroke of the cutting knife 1 is the process of the positioning round rod 22 moving from the intersection of the straight groove 122 and the top of the arc spiral groove 121 (at this time the cutting knife abuts against the door and window profile) to the top of the straight groove 122.

[0043] Furthermore, a groove 27 is provided on the inner wall of the sleeve 21, and the positioning rod 22 is installed in the groove 27 in a sliding fit manner. The positioning rod 22 and the inner wall of the groove 27 are connected by a tightening spring 28. Specifically, when the rotating roller 11 slides toward the top side in the sleeve 21, the positioning rod 22 slides from the straight groove 122 at the top of the rotating roller 11 through the arc-surface protrusion 123 to the straight groove 122 at the bottom of the rotating roller 11. Due to a certain height difference between the arc-surface protrusion 123 and the straight groove 122 at the bottom of the rotating roller 11, the positioning rod 22 passes through the straight groove 122 at the bottom of the rotating roller 11. The arc-surface protrusion 123 needs to shrink to a certain extent. Under the expansion and contraction action of the clamping spring 28, the positioning rod 22 will retract into the groove 27 when passing the arc-surface protrusion 123. When the rotating roller 11 slides toward its bottom end in the sleeve 21, when the positioning rod 22 passes the arc-surface protrusion 123, due to the clamping action of the clamping spring 28, the positioning rod 22 will not slide from the straight groove 122 at the bottom end of the rotating roller 11 to the straight groove 122 at the top end, but will slide from the straight groove 122 to the arc-surface spiral groove 121, so that the positioning rod 22 can slide more stably in the serrated annular groove 12.

[0044] Furthermore, a tightening ring plate 29 is provided on the outer side of the bottom end of the rotating roller 11, and four sleeve rods 210 are evenly installed on the bottom end of the tightening ring plate 29 along its circumferential direction, and tightening rods 211 are installed in the four sleeve rods 210 by sliding fit, and the top ends of the four tightening rods 211 and the inner wall of the sleeve rod 210 are connected by auxiliary springs 212, and tightening blocks 213 are provided on the bottom ends of the four tightening rods 211, and anti-locking blocks 213 are provided on the bottom ends of the four tightening blocks 213. The sliding pad 214 is specifically, (1) when the rotating roller 11 slides toward the bottom side of the sleeve 21, the rotating roller 11 drives the four sleeve rods 210 to move toward the bottom of the sleeve 21. When the positioning round rod 22 slides in the straight groove 122 located at the top of the rotating roller 11 and before the cutting knife 1 performs a cutting operation on the door and window profile, due to the tightening effect of the auxiliary spring 212, the tightening rod 211 drives the tightening block 213 and the anti-slip pad 214 to press against the door and window profile. When the rotating roller 11 continues to drive the cutting knife 1 to slide toward the bottom end of the sleeve 21, the pressure of the pressing block 213 and the anti-skid pad 214 pressing against the top surface of the door and window profile increases under the expansion and contraction action of the auxiliary spring 212, so that the pressing block 213 and the anti-skid pad 214 are more stably positioned on the door and window profile, preventing the door and window profile from being displaced when the cutting knife 1 cuts the door and window profile, thereby ensuring the stability of the cutting of the door and window profile; (2) when the rotating roller 11 slides toward the top end of the sleeve 21, the rotating roller 11 does not rotate, so that the rotating roller 11 does not drive the four sleeve rods 210 to rotate, and when the rotating roller 11 slides toward the bottom end of the sleeve 21, the rotating roller 11 drives the four sleeve rods 210 to rotate, so that the pressing blocks 213 and the anti-skid pads 214 on two of the sleeve rods 210 (that is, the two sleeve rods 210 parallel to the support plate 23) are pressed against the door and window profile.

[0045] Preferably, a collecting barrel 215 is provided at the coaxial position of the lower end of the sleeve 21. Specifically, when the cutting knife 1 cuts the door and window profiles, the cutting knife 1 extends into the collecting barrel 215. Preferably, a negative pressure collection device can be provided in the collecting barrel 215 to perform negative pressure suction during cutting. The debris generated when the cutting knife 1 cuts the door and window profiles is collected through the collecting barrel 215 to prevent the debris of the door and window profiles from splashing.

[0046] Preferably, two pads 216 are symmetrically installed on the top of the collection barrel 215. Specifically, the pads 216 support the door and window profiles so that the door and window profiles are mounted on the two pads 216, and the cutting knife 1 cuts the door and window profiles from the part between the pads 216, so that the cutting knife 1 can extend into the collection barrel 215, and the pads 216 cooperate with the clamping block 213 and the anti-slip pad 214, so that the clamping block 213 and the anti-slip pad 214 clamp the door and window profiles on the pads 216, and the door and window profiles are stably positioned, which provides convenience for the cutting of the door and window profiles.

[0047] Preferably, a bevel discharge plate 217 is installed on the side of the collection barrel 215. Specifically, after the cutting of the door and window profiles is completed, the cut door and window profiles slide out from the bevel discharge plate 217, and the cut door and window profiles are collected.

[0048] Preferably, a baffle 218 is provided at the end of the inclined discharge plate 217 away from the collecting barrel 215. Specifically, after the cut door and window profiles slide out from the inclined discharge plate 217, they are blocked by the baffle 218, thereby reducing the safety hazard of the sharp end of the cut door and window profiles.

[0049] Furthermore, a feed conveying unit 3 is also provided on the support plate 23, and the feed conveying unit 3 is used for intermittent feeding of materials of the same length. The feed conveying unit 3 includes a first roller 31 and a second roller 32, and the first roller 31 is mounted on the support plate 23 in a rotationally matched manner, and the second roller 32 is mounted on the support plate 23 at the bottom end of the first roller 31 in a rotationally matched manner, and the end of the top end of the second roller 32 is at the same height as the cushion block 216, and the edge on the outer wall of the first roller 31 is evenly provided with a plurality of driven blocks 33 along its circumferential direction, and a swing rod 34 is mounted at the center position of the first roller 31 in a rotationally matched manner, and a rotating rod 35 is mounted on the swing rod 34, and a positioning block 36 is mounted on the rotating rod 35. A propulsion block 38 is installed between the positioning block 36 and the swing rod 34 in a rotationally matched manner through a limiting shaft 37, and the propulsion block 38 and the driven block 33 cooperate with each other (the driven block 33 is located on the swing stroke of the propulsion block 38). An auxiliary round rod 39 is arranged on the outer wall of the support plate 23, and the rotating rod 35 and the auxiliary round rod 39 are connected by an assisting spring 310. A feeding motor 311 is installed on the support plate 23 at the bottom end of the auxiliary frame 24, and a feeding disc 312 is installed at the output end of the feeding motor 311. Three feeding rods 313 are evenly installed on the feeding disc 312 along its circumferential direction, and the feeding rod 313 and the rotating rod 35 cooperate with each other. The side wall of the support plate 23 on the side of the first rotating roller 31 away from the collecting barrel 215 is evenly A plurality of first conveying rollers 314 are provided, and the bottom end height of the first conveying rollers 314 is the same as the bottom end height of the first rotating roller 31. A plurality of second conveying rollers 315 are evenly provided on the side wall of the support plate 23 located on the side of the second rotating roller 32 away from the collecting bucket 215, and the top end height of the second conveying roller 315 is the same as the top end height of the second rotating roller 32. Specifically, when it is necessary to feed the door and window profiles, the staff will place the door and window profiles in the part between the first rotating roller 31 and the second rotating roller 32, start the feeding motor 311 to drive the feeding disc 312 to rotate, and the feeding disc 312 drives the three feeding rods 313 to rotate. In the process of the feeding disc 312 driving the three feeding rods 313 to rotate one circle: (1) when one of the feeding rods 3 When the feeding rod 313 rotates to the position of being in close contact with the rotating rod 35, and the feeding rod 313 continues to rotate clockwise, the feeding rod 313 drives the rotating rod 35 and the swing rod 34 to rotate counterclockwise around the first roller 31. When the rotating rod 35 drives the propulsion block 38 to move to the position of being in close contact with the driven block 33, the rotating rod 35 continues to drive the driven block 33 to rotate through the propulsion block 38 (because one side of the propulsion block 38 is in close contact with the side wall of the rotating rod 35 and the other side of the propulsion block 38 is in close contact with the driven block 33, the propulsion block 38 can drive the driven block 33 to rotate), so that the driven block 33 drives the first roller 31 to rotate counterclockwise. At this time, the assisting spring 310 is in a stretched state until one of the feeding rods 313 continues to rotate and disengages from the rotating rod 35.In the process before the separation, the rotating rod 35 drives the first roller 31 to rotate a certain angle through the pushing block 38 and the driven block 33. The rotation angle of the first roller 31 depends on the contact distance between the rotating rod 35 and the feeding rod 313. The longer the contact distance between the rotating rod 35 and the feeding rod 313, the greater the rotation angle of the first roller 31. The greater the rotation angle of the first roller 31, the longer the conveying length of the door and window profile by the first roller 31. (2) After one of the feeding rods 313 and the rotating rod 35 separate from each other, the rotating rod 35 no longer provides rotational power for the feeding rod 313. Under the rebound action of the assisting spring 310, the rotating rod 35 drives the swinging rod 34 to rotate to the initial position with the first roller 31 as the center. Since the pushing block 38 is not pressed against the rotating rod 35 at this time, the pushing block 3 When passing the position of the driven block 33, the push block 38 rotates around the limit shaft 37. Under the tight action of the driven block 33, since the push block 38 is not limited on the side away from the rotating rod 35, the push block 38 rotates around the limit shaft 37 to a position perpendicular to the driven block 33, and then rotates to a position nearly perpendicular to the rotating rod 35 (the push block 38 rotates to a position perpendicular to the rotating rod 35 under the action of gravity), so that the push block 38 will not provide rotational power for the driven block 33, so that the rotating rod 35 will not drive the first roller 31 to rotate during the rotation process. Repeat the above operation, so that when the three feeding rods 313 rotate, they can drive the first roller 31 to rotate a certain angle, so that the first roller 31 can feed the door and window profiles of the same length.

[0050] Preferably, the rotating rod 35 is preferably a telescopic rod, and a telescopic groove 316 is provided at the end of the rotating rod 35, and a driven rod 317 is installed in the telescopic groove 316 in a sliding manner, and a plurality of threaded holes 318 are evenly provided on the driven rod 317. Two auxiliary threaded rods 319 are installed on the outer wall of the telescopic groove 316 and the threaded hole 318 at the opposite end in a threaded manner, and the two auxiliary threaded rods 319 and the threaded holes 318 cooperate with each other. Specifically, by adjusting the contact distance between the feeding rod 313 and the rotating rod 35 during rotation, the rotation angle of the first roller 31 can be adjusted, and the feeding length of the door and window profile by the first roller 31 can be further adjusted. There are two ways of adjustment: one is to adjust the length of the three feeding rods 313; the other is to adjust the length of the three feeding rods 313; To adjust the length of the rotating rod 35, for a more convenient adjustment method, the length of the rotating rod 35 is adjusted. When it is necessary to adjust the length of the rotating rod 35, the staff uses a tool to screw the two auxiliary threaded rods 319 out of the threaded holes 318 on the driven rod 317 at the same time, adjust the position of the driven rod 317 in the telescopic slot 316, and adjust the extended length of the driven rod 317 in the telescopic slot 316, so as to adjust the combined length between the driven rod 317 and the rotating rod 35, so as to make the contact length of the feeding rod 313 with the driven rod 317 and the rotating rod 35, and then screw the two auxiliary threaded rods 319 into the threaded holes 318 on the driven rod 317 at the same time, so as to adjust the combined length between the driven rod 317 and the rotating rod 35, so as to adjust the conveying length of the first roller 31 to the door and window profile.

[0051] Preferably, the top heights of the second rotating roller 32 and the second conveying roller 315 are set to be adjustable, and the height of the collecting bucket 215 or the pad 216 is also set to be adjustable, so as to ensure that the top heights of the second rotating roller 32 and the second conveying roller 315 are the same as the heights of the pad 216. Specifically, by adjusting the top heights of the second rotating roller 32 and the second conveying roller 315, the heights of the collecting bucket 215 or the pad 216, the cutting blade 116 can also be replaced, so as to realize cutting operations on door and window profiles of different widths.

[0052] Preferably, the abutting position of the pushing block 38 and the rotating rod 35 are connected by a tensioning spring 320. Specifically, when the pushing block 38 passes the position of the driven block 33, the pushing block 38 rotates around the limiting shaft 37. Under the abutting action of the driven block 33, the pushing block 38 first rotates to a position perpendicular to the driven block 33 with the limiting shaft 37 as the center (at this time, the tensioning spring 320 is in a stretched state), and then rotates to a position perpendicular to the rotating rod 35 (at this time, the pushing block 38 wants to separate from the driven block 33, and under the pulling action of the tensioning spring 320, the pushing block 38 rotates to a position perpendicular to the rotating rod 35), which can ensure that the pushing block 38 stably rotates to a position parallel to the driven block 33.

[0053] Preferably, a through slot 219 is provided on the side wall of the auxiliary frame 24, an L-shaped rod 220 is provided on the side wall of the propulsion shaft 26, the horizontal section of the L-shaped rod 220 is connected to the side wall of the propulsion shaft 26, a locking rod 221 is installed on the vertical section of the L-shaped rod 220 in a sliding sleeve manner, the locking rod 221 and the output shaft of the feeding motor 311 are used in conjunction with each other, the locking rod 221 and the vertical section of the L-shaped rod 220 are connected by a locking spring 222, specifically, the L-shaped rod 220 and the propulsion shaft 26 are connected. The L-shaped rod 220 is a horizontal section perpendicular to the axis of the feed shaft 26, and the L-shaped rod 220 is a vertical section parallel to the axis of the propulsion shaft 26. (1) When the linear reciprocating motion mechanism 25 drives the rotating roller 11 to slide toward the bottom end of the sleeve 21 through the propulsion shaft 26, that is, after the first roller 31 and the second roller 32 transport the door and window profile to the cutting position, the propulsion shaft 26 drives the L-shaped rod 220 to slide along the track of the through groove 219, and the L-shaped rod 220 drives the lock spring 222 to lock the door and window profile. The locking rod 221 is pressed against the outer wall of the output shaft of the feeding motor 311, so that the locking rod 221 positions the output end of the feeding motor 311, preventing the feeding disc 312 and the feeding rod 313 from rotating when the rotating roller 11 slides toward the bottom end in the sleeve 21, causing the cutting position of the door and window profile to change, thereby ensuring the stability of the cutting of the door and window profile; (2) when the linear reciprocating motion mechanism 25 drives the rotating roller 11 to slide toward the top end in the sleeve 21 through the propulsion shaft 26, the linear reciprocating motion mechanism 25 drives the rotating roller 11 to slide toward the top end in the sleeve 21. During the sliding process on one side, that is, after the cutting of the door and window profiles is completed, the propulsion shaft 26 drives the L-shaped rod 220 to slide along the trajectory of the through groove 219, and the L-shaped rod 220 drives the locking rod 221 to slide toward the side of the output shaft away from the feeding motor 311 through the locking spring 222, so that the locking rod 221 releases the positioning operation on the output end of the feeding motor 311, so that the feeding motor 311 can continue to drive the feeding disc 312 and the feeding rod 313 to rotate, and continue to feed the door and window profiles.
