[0022] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0023] Example 1, reference Figure 1-Figure 5A material unloading device for aluminum profile cutting equipment comprises a cutting table 1, a conveyor belt 2 is arranged on the outer wall of one side of the cutting table 1, and a support plate 5 is fixedly connected to the outer wall of the other side of the cutting table 1, an aluminum profile 3 is placed on the cutting table 1 and the conveyor belt 2, and a cutting mechanism is arranged on the top of the cutting table 1, and fixing mechanisms are arranged on both sides of the cutting mechanism, a U-shaped frame 19 is slidably connected to the outer wall of the top of the support plate 5, and an electric push rod 3 18 is fixedly connected between the U-shaped frame 19 and the outer wall of the cutting table 1, vertical plates 22 are fixedly connected to the inner walls of both ends of the U-shaped frame 19, and the middle outer walls of the two vertical plates 22 away from the electric push rod 3 18 are fixed. A receiving box 20 is connected, two rotating shafts 24 are connected to the rotating wheel between the two vertical plates 22, and a driving motor 21 is set at one end of one of the rotating shafts 24, and a telescopic mechanism is set in each of the two receiving boxes 20, and a rotating shaft 24 is also set between the two telescopic mechanisms. The outer walls of the three rotating shafts 24 are sleeved with the same grinding belt 23, and the aluminum profile 3 is transported by the conveyor belt 2 to the cutting table 1. When it reaches a certain length, the conveyor belt 2 stops running. At this time, the fixing mechanisms on both sides of the cutting mechanism start to run, so that the fixing mechanism fixes the aluminum profile 3, and then the cutting mechanism starts to work to cut the aluminum profile 3. The aluminum profile 3 is cut, and when the aluminum profile 3 is cut, the electric push rod 3 18 is started to move the U-shaped frame 19 on the support plate 5 toward the cutting table 1. At the same time, the telescopic mechanism in the receiving box 1 20 is controlled to make the grinding belt 23 set on the three rotating shafts 24 in a taut state become loose. As the U-shaped frame 19 continues to move, the loosened grinding belt 23 will contact the cut end of the aluminum profile 3 until the loosened grinding belt 23 wraps the cut end of the aluminum profile 3, and then the telescopic mechanism is controlled again to make the grinding belt 23 taut. At this time, the grinding belt 23 still wraps the aluminum profile 3. The cut end is wrapped, and then the driving motor 21 drives the rotating shaft 24 connected thereto to rotate, which can make the grinding belt 23 move, so that the moving grinding belt 23 can grind the cut part of the aluminum profile 3 to remove the burrs generated during cutting, and no manual trimming is required, thereby avoiding accidental injury by burrs during manual handling. When the grinding is completed, the aluminum profile 3 is also cut, and then the fixing mechanism no longer fixes the aluminum profile 3. At this time, the cut aluminum profile 3 is transported, and the conveyor belt 2 continues to convey the aluminum profile 3 above it, and the above operation is repeated to complete the cutting of the aluminum profile 3.

The magnetic force generated by the electromagnet 25 after being energized repel the magnetic plate 27, and one of the rotating shafts 24 is rotatably connected between the two telescopic plates 28. Since the magnetic force generated by the electromagnet 25 after being energized repel the magnetic plate 27, the electromagnet 25 can be energized. The magnetic plate 27 is enough to stretch the connecting spring 26 away from the electromagnet 25, and the telescopic plate 28 extends out of the containing box 20 to a longer length. If the current input into the electromagnet 25 is reduced, the magnetic force generated by the electromagnet 25 will be reduced. Under the action of the rebound force of the connecting spring 26, the magnetic plate 27 will approach the electromagnet 25, thereby shortening the length of the telescopic plate 28 extending out of the containing box 20. At this time, the taut grinding belt 23 becomes loose, and the current input into the electromagnet 25 is increased, so that the magnetic force generated by it will become larger, so that the length of the telescopic plate 28 extending out of the containing box 20 will become longer again, thereby making the loose grinding belt 23 become taut.

[0025] As a further solution in the present invention, the cutting mechanism includes a mounting frame 4, an electric push rod 29 is installed on the top of the mounting frame 4, and the telescopic end of the electric push rod 29 is fixedly connected to a drive motor 11, and the output shaft end of the drive motor 11 is fixedly connected to a cutting blade 10. A controller 12 is provided on the outer wall of the mounting frame 4. The drive motor 11 rotates the cutting blade 10, and the cutting blade 10 is moved up and down by the electric push rod 29, thereby completing the cutting work of the aluminum profile 3.

[0026] As a further solution in the present invention, the fixing mechanism includes a fixing plate 8, which is fixedly connected to the mounting frame 4, and an electric push rod 7 is fixedly connected to the bottom outer wall of the fixing plate 8, and a pressing plate 6 is fixedly connected to the telescopic ends of the electric push rod 7. The fixing plate 8 is moved downward by the electric push rod 7 until it contacts the surface of the aluminum profile 3, thereby completing the fixation of the aluminum profile 3 and avoiding shaking of the aluminum profile 3 during the cutting process.

[0027] As a further solution in the present invention, a material drop port 15 is provided on the outer wall of the top of the cutting table 1, and a collecting chamber 16 is connected below the material drop port 15, a collecting bucket 13 is slidably connected to the bottom of the collecting chamber 16, a triangular plate 14 is fixedly connected inside the collecting chamber 16, and a plurality of air holes are provided on the outer wall of the triangular plate 14, fans 17 are provided on the outer walls on both sides of the bottom of the triangular plate 14, when cutting, the fan 17 at the bottom of the triangular plate 14 is started, so that the waste chips generated when the cutting blade 10 cuts the aluminum profile 3 are sucked into the material drop port 15, and finally fall into the collecting bucket 13 along the triangular plate 14, so as to avoid the waste chips flying around in the working environment and endangering the human body, and at the same time facilitate the subsequent disposal of the waste chips.

[0028] Working principle: The aluminum profile 3 is conveyed by the conveyor belt 2 and conveyed to the cutting table 1. When it reaches a certain length, the conveyor belt 2 stops running. At this time, the fixing mechanisms on both sides of the cutting mechanism start to run, so that the fixing mechanism aluminum profile 3 is fixed, and then the cutting mechanism starts to work to cut the aluminum profile 3. When the aluminum profile 3 is cut, the electric push rod 3 18 is started to move the U-shaped frame 19 on the support plate 5 toward the cutting table 1, and after the electromagnet 25 is energized, the magnetic plate 27 can stretch the connecting spring 26 away from the electric The magnet 25 makes the telescopic plate 28 extend longer from the receiving box 20, so that the grinding belt 23 is in a taut state, and then the current input into the electromagnet 25 becomes smaller, so that the magnetic force generated by the electromagnet 25 becomes smaller, and under the action of the rebound force of the connecting spring 26, the magnetic plate 27 will approach the electromagnet 25, so that the length of the telescopic plate 28 extending out of the receiving box 20 is shortened, and the taut grinding belt 23 becomes loose, so that the taut grinding belt 23 set on the three rotating shafts 24 becomes loose. As the frame 19 continues to move, the loosened grinding belt 23 will contact the cut end of the aluminum profile 3 until the loosened grinding belt 23 wraps the cut end of the aluminum profile 3, and then the current input to the electromagnet 1 25 is increased to increase the magnetic force generated by it, so that the length of the telescopic plate 1 28 extending out of the receiving box 1 20 will be extended again, so that the loosened grinding belt 23 becomes taut. At this time, the grinding belt 23 still wraps the cut end of the aluminum profile 3, and then the driving motor 21 drives the rotating shaft connected to it. 24 rotates to move the grinding belt 23, so that the moving grinding belt 23 can grind the cut portion of the aluminum profile 3 to remove burrs generated during cutting without manual trimming, thereby avoiding accidental injury by burrs during manual handling. When the grinding is completed, the aluminum profile 3 is also cut, and then the fixing mechanism no longer fixes the aluminum profile 3. At this time, the cut aluminum profile 3 is transferred, and the conveyor belt 2 continues to convey the aluminum profile 3 above it, and the above operation is repeated to complete the cutting of the aluminum profile 3.

When the grinding belt 23 approaches the cutting part of the aluminum profile 3 and wraps it.

[0030] As a further solution in the present invention, a receiving box 32 is provided on both sides of the pressing roller 30, and the receiving boxes 32 are installed in the corresponding slots 29, an electromagnet 35 is provided on the inner wall of the bottom of the receiving box 32, and a telescopic plate 33 is slidably connected to the top of the receiving box 32, and the pressing roller 30 is rotatably connected between the two telescopic plates 33, so that the electromagnet 35 in the receiving box 32 is energized.

[0031] As a further solution in the present invention, the bottom end of the telescopic plate 2 33 is fixedly connected with a magnetic plate 2 31, and a connecting spring 2 34 is fixedly connected between the magnetic plate 2 31 and the electromagnet 2 35. The magnetic force generated by the electromagnet 2 35 after being energized repels the magnetic plate 2 31, and can cause the magnetic plate 2 31 to stretch the connecting spring 2 34 to move, thereby lengthening the telescopic plate 2 33 extending out of the accommodating box 2 32, and causing the pressing roller 30 to squeeze the grinding belt 23, so that the grinding belt 23 can be closely attached to the upper and lower surfaces of the cut part of the aluminum profile 3, avoiding the situation where dead corners cannot be polished, thereby greatly improving the grinding effect.

[0032] Working principle: When the grinding belt 23 approaches the cut part of the aluminum profile 3 and wraps it, the electromagnet 2 35 in the receiving box 2 32 is energized. The magnetic force generated by the electromagnet 2 35 after being energized repel the magnetic plate 2 31, so that the magnetic plate 2 31 can stretch the connecting spring 2 34 to move, thereby making the telescopic plate 2 33 extend out of the receiving box 2 32 longer, so that the pressing roller 30 squeezes the grinding belt 23, so that the grinding belt 23 can be closely attached to the upper and lower surfaces of the cut part of the aluminum profile 3, avoiding the situation where dead corners cannot be polished, and greatly improving the polishing effect.

When the grinding belt 23 moves for grinding, the rotating shaft 24 will rotate, so that the roller cleaning brush 40 can be rotated through the transmission belt 39. Because the roller cleaning brush 40 is in contact with the surface of the grinding belt 23, the roller cleaning brush 40 can clean the surface of the grinding belt 23, remove residual waste chips, and improve the grinding effect of the grinding belt 23.

[0034] As a further solution in the present invention, one side of the dust hood 36 is connected to a dust suction pipe 37, and a dust collector 38 is provided at one end of the dust suction pipe 37.

When the airflow flows, it absorbs the cleaned waste chips and cleans the roller cleaning brush 40 at the same time to avoid waste chips adhering to the roller cleaning brush 40, keep the roller cleaning brush 40 clean, and improve the cleaning effect.

[0035] Working principle: When the grinding belt 23 moves for grinding, the rotating shaft 24 will rotate, so that the roller cleaning brush 40 can rotate through the transmission belt 39. Since the roller cleaning brush 40 is in contact with the surface of the grinding belt 23, the roller cleaning brush 40 can clean the surface of the grinding belt 23, remove the residual waste chips, and improve the grinding effect of the grinding belt 23. At the same time, the vacuum cleaner 38 will start, and a huge suction force will be generated through the vacuum pipe 37, so that the airflow flows on the surface of the grinding belt 23 and the roller cleaning brush 40.
