DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] It is to be noted that the concepts of directions “left”, “right”, “up”, “down”, “front”, “back”, “inside” and “outside” in the following schemes are all relative directions and will not be listed one by one here.

[0022] An aluminum door frame cutting device, see Figure 1-Figure 4 , including a conveying assembly 1, a cutting assembly 2 and a material unloading rack 3 arranged in sequence. The conveying assembly 1 is a commonly used conveying device in the art. Due to the prior art, the specific structure is not described in detail here. A plurality of lateral conveyor belts 5 are arranged on one side of the conveying assembly 1. The conveying direction of the lateral conveyor belts 5 is perpendicular to the conveying direction of the conveying assembly 1.

[0023] The cutting assembly 2 includes a cutting table 21. A cutting cover 22 is provided on the cutting table 21. The cutting cover 22 is provided with matching openings at one end close to the conveying assembly 1 and at one end away from the conveying assembly 1 for the aluminum profile to pass through. A slide groove 23 is provided on the cutting table 21, and a high-speed rotating cutting knife 24 is slidably provided at the slide groove 23. A smoke collector 6 is connected to the upper side of the cutting cover 2 for collecting smoke generated when cutting the aluminum profile. The smoke collector 6 adopts an existing device, and due to the existing technology, the specific structure will not be described in detail here.

[0024] The cutting table 21 is hollow inside. A motor 26 and a rotating column 29 are slidably arranged in the cutting table 21, and the moving direction is the same as that of the cutting knife 24. A first rack 25 is arranged in the cutting table 21, and the moving direction is the same as that of the cutting knife 24. A first transmission rod 27 is arranged at the output end of the motor 26. A first gear 28 meshing with the first rack 25 is fixedly sleeved on the first transmission rod 27. A speed increasing housing 7 is arranged at the end of the first transmission rod 27. The speed increasing housing 7 is connected to the center of the cutting knife 24. A second gear 71 and a third gear 72 meshing with each other are rotatably arranged in the speed increasing housing 7. The radius of the second gear 71 is much larger than that of the third gear 72. The second gear 71 is connected to the first transmission rod 27, and the third gear 72 is connected to the center of the cutting knife 24. The center of the cutting knife 24 away from the cutting housing 7 is rotatably connected to the rotating column.

[0025] When the motor 26 is working, the first gear 28 rotates, thereby driving the cutting blade 24. The motor 26 moves and drives the cutting blade 24 to rotate. Since the second gear 71 and the third gear 72 are meshed, the output rate is amplified, so that the cutting blade 24 rotates at a high speed.

[0026] A second rack 31 is provided on the upper side of the side walls on both sides of the unloading rack 3. A limiting body 4 is provided at one end of the unloading rack 3 away from the cutting assembly 2. The limiting body 4 is hollow inside and open at the bottom. The limiting body 4 is slidably mounted on the unloading rack 3. A clamping cylinder 48 is provided on both sides of the limiting body 4. A pressing plate 47 connected to the clamping cylinder is provided in the limiting body 4, and a third rack 46 matching the second rack 31 is slidably provided. The pressing plate 47 is located directly above the third rack 46. Guide rods 49 are provided at both ends of the pressing plate 47. The guide rod 49 is provided through the limiting body 4. The operator can control the clamping cylinder 48 to stop clamping the second rack 31 according to actual needs, and manually move the limiting body 4 to roughly adjust the position of the limiting plate 41. When it moves to a suitable position, the clamping cylinder 48 is started, and the pressing plate 47 presses the third rack 46 tightly against the second rack 31, thereby fixing the position of the limiting body 4.

[0027] A telescopic cylinder 42 is provided at one end of the limiting body 4 close to the cutting assembly 2. A movable plate 43 is provided at the output end of the telescopic cylinder 42. The limiting plate 41 and the movable plate 43 are relatively parallel. Four screws 44 are provided on one side of the limiting plate 41 close to the movable plate 43. The limiting plate 41 is slidably sleeved on the four screws 44. Two adjusting nuts 45 are provided on the four screws 44 for threaded rotation. The two adjusting nuts 45 are respectively located on both sides of the movable plate 43 and abut against the movable plate 43. The position of the limiting plate 41 is finely adjusted by the telescopic cylinder 42, and the position of the limiting plate 41 is finely adjusted by changing the position of the adjusting nut 45.

[0028] After adjusting the position of the limiting plate 41, the lateral conveyor belt 6 delivers the aluminum profile to the conveying assembly 1. The conveying assembly 1 conveys the aluminum profile forward until it contacts the limiting plate 41. At this time, the cutting knife 24 moves to cut the aluminum profile, and the cut aluminum profile is the required door frame size aluminum profile. The worker only needs to take the cut aluminum profile out of the drop frame 3.

[0029] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above description or the technology or knowledge of the relevant field.
