Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 - Fig. 9 The present invention provides a technical solution, which specifically includes the following embodiments: Embodiment 1: A multi-station cutting device for door and window profiles comprises a frame 1, on which a conveying station 2, a cutting station 3 and a discharge station 4 are installed, wherein the conveying station 2 is used for conveying the profile 10 before cutting, the cutting station 3 is used for positioning, clamping and cutting the profile 10, and the discharge station 4 is used for conveying the profile 10 after cutting; The cutting station 3 includes a loading and unloading mechanism 30, a positioning assembly 31, a clamping assembly 32 and a cutting assembly 33. The loading and unloading mechanism 30 includes a rotating disk 301, and the rotating disk 301 is driven by an intermittent rotating motor 302. A plurality of support rods 303 are fixed on the rotating disk 301, and a plurality of placement frames 304 are fixed between the support rods 303. The placement frames 304 can place the profile 10, and the outer contour of the placement frames 304 is a trapezoid; The placement frame 304 is equipped with a hooking mechanism 5, and the hooking mechanism 5 hooks the profile 10 and puts it into the placement frame 304. The profile 10 in the placement frame 304 is confined at the center of the placement frame 304 by the positioning component 31 and the clamping component 32. The cutting component 33 is installed on the top of the frame 1, and the cutting component 33 is used to cut the profile 10 in the placement frame 304. The intermittent rotating motor 302 is connected to the control module.

[0020] The present invention arranges a conveying station 2, a cutting station 3 and an unloading station 4 to make the processing process orderly and improve production efficiency. In addition, the cutting station 3 can realize the loading of the profile 10 before cutting, the clamping and positioning during cutting, and the unloading of the profile 10 after cutting, thereby replacing manual labor, continuous cutting, and improving the processing efficiency of door and window profiles.

[0021] As a further explanation of this embodiment, the conveying station 2 and the unloading station 4 are respectively arranged on both sides of the two placement frames 304 in the horizontal direction, and the conveying station 2 and the unloading station 4 are sprocket conveyors. The sprocket conveyors are linked and controlled with the intermittent rotating motor 302 through the PLC program, and the sprocket conveyors intermittently transport the profiles 10, which cooperates with the intermittent rotation of the intermittent rotating motor 302.

[0022] Among them, the transport shaft of the sprocket conveyor is as follows Figure 2 As shown, the middle is discontinuous, which makes it easier for the hooking mechanism 5 to hook the profile 10.

[0023] The cutting assembly 33 includes a hydraulic pump 71 and a saw blade cutter 72, and the output end of the hydraulic pump 71 is fixedly connected to the saw blade cutter 72. The output end of the hydraulic pump 71 descends to drive the saw blade cutter 72 to descend, and saws the profile 10. After the sawing is completed, the output end of the hydraulic pump 71 drives the saw blade cutter 72 to rise and reset. The initial position of the saw blade cutter 72 is located above the placement frame 304. After resetting, it does not affect the continued rotation of the placement frame 304. The cutting assembly 33 is symmetrically arranged in two groups, because the profile 10 is mostly cut at both ends. And the cutting assembly 33 is installed on the frame 1 through a slewing bearing, and can rotate a certain angle to meet the cutting requirements.

[0024] The intermittent rotating motor 302 controls the rotating disk to rotate 301, and the angle of each rotation is the angle between the center of one placement frame 304 and the center of another placement frame 304. The time interval of the rotation is slightly greater than the time it takes for the saw blade cutting machine 72 to cut the profile 10 once.

[0025] The bottom of the placing frame 304 is provided with two symmetrical material dropping openings 80, and a special-shaped funnel 81 is arranged below the material dropping openings 80. The special-shaped funnel 81 is fixedly connected to a collecting box 82, and the collecting box 82 is fixed to the frame 1. The present invention is cut by a saw blade cutting machine 72, and the material dropping openings 80 can, on the one hand, cut through the profile 10, and on the other hand, allow the cut waste to enter the special-shaped funnel 81 and then enter the collecting box 82, thereby separating the profile 10 from the waste.

[0026] During operation: the rotating disk 301 is circular and can be divided into four areas. The left side is the loading area, which is used to hook the profile 10 on the conveying station 2 into the placement frame 304 through the hooking mechanism 5; the top is the cutting area, when the placement frame 304 rotates to the bottom, the saw blade cutting machine 72 in the cutting assembly 33 is driven down by the hydraulic pump 71 to cut the profile 10, the right side is the unloading area, and the cut profile 10 slides from the placement frame 304 to the unloading station 4; the bottom is the transition area, and the placement frame 304 is unloaded. Prepare for loading; when the placement frame 304 rotates from the loading area to the top cutting area, the profile 10 is hooked into the placement frame 304 by the hooking mechanism 5, and the positioning component 31 and the clamping component 32 move the center of the profile 10 from the surrounding directions of the profile 10 to the center position in the placement frame 304, and the profile 10 is clamped and positioned. When the profile 10 rotates from the top cutting area to the unloading area on the right, the positioning component 31 and the clamping component 32 are reset, the clamping of the profile 10 is cancelled, and the profile 10 slides to the unloading station 4.

[0027] As a further explanation of this embodiment, refer to Figure 1~Figure 4 The hooking mechanism 5 includes a first connecting rod 51, one end of which overlaps the surface of the convex ring 50, and the convex ring 50 is fixed to the frame 1. The other end of the first connecting rod 51 is fixed to the first rotating shaft 52. The first rotating shaft 52 is connected to the side wall of the placement frame 304 by a bearing. Two hook plates 53 are fixed on the first rotating shaft 52. One end of the first return spring 54 is fixed on the first rotating shaft 52. The other end of the first return spring 54 is fixed to the side wall of the placement frame 304. Two opening grooves 55 are provided on the placement frame 304, and the two hook plates 53 rotate through the opening grooves 55.

[0028] When working, the loading and unloading mechanism 30 is started, and the rotating disk 301 rotates. When the idle placement frame 304 at the bottom rotates to the left horizontal position, the first connecting rod 51 gradually rotates from the concave surface of the convex ring 50 to the convex surface, which drives the first rotating shaft 52 to swing upward, so that the two hook plates 53 lift the profile 10 on the conveying station 2, and the profile 10 slides along the inner wall of the placement frame 304 to the bottom; When the first connecting rod 51 moves to the transition point from the convex surface of the convex ring 50 to the concave surface, it is reset under the traction of the first reset spring 54 . At this time, the cut profile 10 slides along the hook plate 53 to the unloading station 4 .

[0029] The present invention provides a hooking mechanism 5, and controls the hook plate 53 to hook the profile 10 into the placement frame 304 through the convex ring 50, thereby improving the degree of automation and replacing manual loading.

[0030] As a further explanation of this embodiment, refer to Figure 7~Figure 9The positioning assembly 31 includes a pressing plate 3001, and the pressing plate 3001 moves along the through hole 3010, and the through hole 3010 is opened on the bottom surface of the placement frame 304. The pressing plate 3001 is fixed to one end of the second connecting rod 3002, and the other end of the second connecting rod 3002 is fixed to the first slider 3003. The first slider 3003 moves along the first guide rail 3004, and the first guide rail 3004 is fixed to the placement frame 304. The first slider 3003 is fixed to one end of the second spring 3005, and the other end of the second spring 3005 is fixed to the placement frame 304. The second connecting rod 3002 is fixedly connected to the first rack 3006, and the first rack 3006 is meshed with the first gear 3007. The first gear 3007 is connected to the bearing of the placement frame 304, and the first gear 3007 is also meshed with the second rack 3008 and the third rack 3009, the second rack 3008 and the third rack 3009 are respectively located on the upper side and the lower side of the first gear 3007, the second rack 3008 and the third rack 3009 are respectively installed on two sets of positioning kits, the two sets of positioning kits are symmetrically arranged about the first gear 3007, the positioning kit includes a first guide rod 3101, the two first guide rods 3101 are respectively fixed to the second rack 3008 and the third rack 3009, the first guide rod 3101 moves along the second guide rail 3106, the second guide rail 3106 is fixed to the placement frame 304, the first guide rod 3101 is fixed with a limit plate 3103, the limit plate 3103 can pass through the guide hole 3104 opened in the placement frame 304 and overlap with the profile 10.

[0031] During operation, when the hooking mechanism 5 causes the profile 10 to slide into the placement frame 304, the center of the profile 10 needs to be moved to the center of the placement frame 304 before cutting to facilitate positioning and cutting. The profile 10 will fall onto the pressing plate 3001, and the deadweight of the profile 10 will cause the pressing plate 3001 to drop below the surface of the placement frame 304, so that the bottom surface of the profile 10 fits with the bottom surface of the placement frame 304. The weight of each profile 10 is substantially the same, so the pressing plate 3001 drops a certain distance, driving the first rack 3006 to drop, causing the first gear 3007 to rotate counterclockwise, thereby causing the second rack 3008 and the third rack 3009 to retract, causing the first guide rod 3101 to retract, thereby causing two symmetrical limiting plates 3103 to overlap with the profile 10, and the limiting plates 3103 push the profile 10 until its width center coincides with the width center of the placement frame 304 and clamps it; After the cutting is completed, the waste materials on both sides fall into the blanking opening 80, and the overall weight of the profile 10 changes, so the pressing plate 3001 rises back and the two limiting plates 3103 open, allowing the profile 10 to slide down.

[0032] The limiting plate 3103 is connected to a wheel 3105 on a bearing, and the end surface of the wheel 3105 is parallel to the bottom surface of the placement frame 304. The limiting plate 3103 pushes the profile 10 to coincide with the width center of the placement frame 304 and clamps the profile 10, and the profile 10 can also move in the length direction of the profile 10.

[0033] As a further explanation of this embodiment, refer to Figure 5~Figure 6 The clamping assembly 32 includes a lead screw 601, which is connected to the placement frame 304 through a bearing, one end of the lead screw 601 is coaxially fixed with the second gear 602, and the second gear 602 can intermittently mesh with the first arc-shaped rack 603 and the second arc-shaped rack 604 respectively, the first arc-shaped rack 603 and the second arc-shaped rack 604 are respectively fixed on the first ring 605 and the second ring 606, the first ring 605 and the second ring 606 are fixed to the frame 1, and the other end of the lead screw 601 The guide sleeve 608 is connected to the guide rail 609, the guide rail 609 is fixed to the placement frame 304, the guide sleeve 608 is connected to the guide rail 609, the guide rail 609 is fixed to the placement frame 304, the guide sleeve 608 is fixed to one end of the bending rod 610, the other end of the bending rod 610 is fixed to the push plate 612 through the long hole 611, the long hole 611 is provided on the bottom surface of the placement frame 304, and the push plate 612 can overlap with the profile 10; The two groups of clamping assemblies 32 are symmetrically arranged about the center of the placement frame 304 .

[0034] The first arc-shaped rack 603 and the second arc-shaped rack 604 are respectively located at the bottom and the top of the second gear 602, so that the meshing positions are different, so that the second gear 602 can rotate in the forward and reverse directions.

[0035] The first arc-shaped rack 603 and the second arc-shaped rack 604 have the same number of teeth, ensuring that the lead screw 601 rotates the same number of times.

[0036] When working, the positioning assembly 31 pushes the profile 10 to the point where its width center coincides with the width center of the placement frame 304 and is clamped, while the placement frame 304 rotates from the left horizontal position to the original position of the other placement frame 304, the second gear 602 engages with the first arc-shaped rack 603, the second gear 602 rotates clockwise, the lead screw 601 rotates, and drives the guide sleeve 608 to move to the limit block 607, so that the bending rod 610 drives the push plate 612 to overlap the side of the profile 10, until the two push plates 612 push the profile 10 to the point where its length center coincides with the length center of the placement frame 304 and is clamped, at which time the second gear 602 disengages from the first arc-shaped rack 603 and no longer rotates; After the cutting at the top is completed, the placement frame 304 at the top rotates clockwise. During this process, the second gear 602 engages with the second arc-shaped rack 604, and the second gear 602 rotates counterclockwise, and the guide sleeve 608 is reset, driving the push plate 612 to separate from the profile 10, and no longer clamping, so that the profile 10 slides to the unloading station 4.
