Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profiles, and more particularly to aluminum profile extrusion equipment. Background Art

[0002] The aluminum extrusion process first prepares the billet and heats it to around 400-500°C. A suitable die is then installed, and the heated billet is placed in the extrusion barrel. Pressure is applied through the extrusion rod to extrude it from the die hole. After extrusion, it is promptly cooled by air or water cooling, followed by stretching and straightening to improve deformation. Appropriate surface treatment methods such as anodizing and electrophoretic coating are then selected to improve performance.

[0003] In the current field of aluminum extrusion technology, the problem of residual impurities on the inner wall of the extrusion barrel has always been a key factor restricting production quality and efficiency. During the extrusion process, the interaction between the alloy billet and the inner wall of the extrusion barrel causes impurities such as metal debris and lubricant residue to adhere to the barrel wall. If these impurities are not cleaned in time, they will directly affect the surface quality and dimensional accuracy of the subsequent extruded profiles. In the existing technology, the inner wall is usually cleaned immediately after a single extrusion. Although this can ensure the extrusion effect, the frequent shutdown for cleaning not only interrupts the production process, but also significantly reduces equipment utilization and overall production efficiency, making it difficult to meet the modern industry's demand for efficient and continuous production.

[0013] The beneficial effects of the present invention compared with the prior art are: (1) When the top block and the aluminum cylinder of the present invention move toward the double-cavity cylinder, the spring 1 provides elastic force to move the slide bar 1 and the pressure plate 1 toward the double-cavity cylinder, so the push rod moves synchronously. At this stage, the gear 1 is engaged with the rack 1, and the gear 1 drives the rack 1 to rotate in the positive direction. The rack 1 drives the outer ring of the one-way bearing to rotate synchronously, and the inner ring of the one-way bearing also rotates. Then, the power is transmitted through the vertical rotation rod, the bevel gear 1, the bevel gear 2, the horizontal rotation rod, and the transmission mechanism 1 to rotate the double-cavity cylinder. When the gear 1 completely passes the rack 1, the double-cavity cylinder rotates 180 degrees. Therefore, the two extrusion chambers of the double-cavity cylinder are swapped, which is convenient for cleaning the extrusion chamber used last, and the entire production process does not stop, thereby improving production efficiency.

[0014] (2) When the top block and the aluminum cylinder of the present invention move toward the double-cavity cylinder, spring 2 provides elastic force, causing slide rod 2 to move toward the extrusion head. The pressure plate and the slide rod begin to contact each other, and the pressure plate drives the slide rod to move toward the double-cavity cylinder. The slide rod causes spring 3 to be inserted into the extrusion cavity below. At the same time, power is transmitted through pressure plate 2, and the motor drives slide seat 1 to rotate. Slide seat 1 drives slide rod to rotate, and slide rod drives spring 3 to rotate. Therefore, spring 3 cleans the extrusion cavity below, removing the residual material adhered to the inside of the extrusion cavity during the previous extrusion, thereby preventing the surface quality from being reduced during the next extrusion.

[0015] (3) The aluminum tube material of the present invention passes through the cleaning table, and the sliding rod drives the sliding seat 2 to rotate, which is transmitted through the transmission mechanism 3, driving the rotating shaft and the two guide wheels to rotate. The rotation directions of the two guide wheels are consistent, and the aluminum tube material contacts the two guide wheels. The guide wheels drive the aluminum tube material to rotate, and the aluminum tube material rotates on the grinding wheel, that is, the grinding wheel contacts the surface of the aluminum tube material, and grinds off the oxide layer on the surface of the aluminum tube material, thereby improving the quality of aluminum profile extrusion.

[0016] (4) The telescopic shaft of the hydraulic cylinder of the present invention contracts. When the lever on the push rod contacts the inclined groove, the top of the lever pushes the triangular block upward, and the triangular block moves upward synchronously with the connecting rod and rack 3. Spring 4 begins to contract, and the gear lever 2 extends above the gear lever 1. Spring 5 blocks all aluminum tubes except the bottom aluminum tube. At the same time, the connecting rod moves upward synchronously with rack 3, and the power is transmitted through gear 2, causing rack 2 and the frame to move downward. Therefore, all gear levers 1 retract to the lower position, and the bottom aluminum tube moves to the unloading platform. At this time, the telescopic shaft of the hydraulic cylinder is in a fully contracted state, so the loading of the aluminum tube is automatically completed, which facilitates operation and improves work efficiency.

[0017] (5) The motor of the present invention drives the cutting disc to rotate, starts the electric cylinder, and the telescopic shaft of the electric cylinder extends. The telescopic shaft of the electric cylinder drives the moving seat to move downward. The telescopic shaft of the electric cylinder moves synchronously with the auxiliary plate, and the power is transmitted through spring six. The auxiliary plate moves downward synchronously with the guide rod, the pressure rod and the rack four, and then transmits power through gear three, so that the connecting shaft and the support frame rotate synchronously on the rotating seat. When the support frame rotates ninety degrees, the support frame contacts the baffle. At this time, the support frame no longer rotates, and the support frame contacts the aluminum profile. When the telescopic shaft of the electric cylinder continues to extend, the spring six begins to compress, and the support frame no longer rotates. The support frame holds the aluminum profile, which is convenient for the cutting disc to cut the aluminum profile, making the cutting more even. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In the present invention, unless otherwise specified, directions such as "up" and "down" are generally used with respect to the directions shown in the drawings, or with respect to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" are generally used with respect to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directions are not used to limit the present invention.

[0030] Example 1: Please refer to Figures 1-10 Structural schematic diagram, the present invention provides the following technical solutions: an aluminum profile extrusion equipment, including a frame 1, a discharge table 3 for placing an aluminum tube 2 is provided on the frame 1, a center table 4 is provided on the side of the aluminum tube 2 on the frame 1, a cleaning table 5 flush with the aluminum tube 2 is provided on the center table 4, a hydraulic cylinder 6 is provided on the frame 1, a top block 7 for driving the aluminum tube 2 to move is provided at the end of the telescopic shaft of the hydraulic cylinder 6, a double-cavity cylinder 8 is rotatably provided on the side of the cleaning table 5 on the frame 1, the double-cavity cylinder 8 is provided with two extrusion cavities 801 for limiting the aluminum tube 2, a tail table 9 is provided on the side of the double-cavity cylinder 8 on the frame 1, and an extrusion head 10 for extruding the aluminum tube 2 is provided on the tail table 9.

[0031] Specifically, the aluminum tube 2 is placed on the unloading table 3, and the hydraulic cylinder 6 is started to extend the telescopic shaft of the hydraulic cylinder 6. The telescopic shaft of the hydraulic cylinder 6 drives the top block 7 to move toward the double-cavity cylinder 8, so the top block 7 pushes the aluminum tube 2 along the unloading table 3 and the cleaning table 5 toward the double-cavity cylinder 8. The top block 7 pushes the aluminum tube 2 into the extrusion cavity 801, and the double-cavity cylinder 8 then passes through the extrusion head 10. The top block 7 applies extrusion force to the aluminum tube 2, and the extrusion cavity 801 limits the aluminum tube 2. What is extruded from the extrusion head 10 is the extruded aluminum profile.

[0032] A slide rod 11 is provided on the frame 1, and a pressure plate 12 in contact with the top block 7 is provided at one end of the slide rod 11. A spring 13 is provided on the outer sleeve of the slide rod 11, and the two ends of the spring 13 are respectively connected to the frame 1 and the pressure plate 12. A push rod 14 is provided at the other end of the slide rod 11, and the push rod 14 is slidably provided on the frame 1. A one-way drive device is provided between the push rod 14 and the rotating shaft of the double-chamber cylinder 8.

[0033] The one-way drive device includes a gear 15 fixed to the end of the push rod 14, and a rack 16 is provided on the side of the gear 15. The rack 16 is connected to the outer ring of the one-way bearing 17, and the inner ring of the one-way bearing 17 is connected to the vertical rotation rod 18. The vertical rotation rod 18 is rotatably arranged on the frame 1, and a bevel gear 1901 is provided on the vertical rotation rod 18. The side of the bevel gear 1901 is engaged with a bevel gear 2 1902, and the bevel gear 2 1902 is fixed to one end of the transverse rod 20, and the transverse rod 20 is rotatably arranged on the frame 1. A rotating wheel of the transmission mechanism 21 is fixed to the other end of the transverse rod 20, and the other rotating wheel of the transmission mechanism 21 is fixed on the rotating shaft of the double-cavity cylinder 8.

[0034] When the outer ring of one-way bearing 17 rotates forward, its inner ring also rotates forward simultaneously. When the outer ring of one-way bearing 17 rotates backward, its inner ring stops rotating. Transmission mechanism 1 21 consists of two rotating wheels and a transmission belt, which is wrapped around both wheels. When one transmission wheel rotates, power is transmitted through the transmission belt, driving the other transmission wheel to rotate.

[0035] Specifically, when the telescopic shaft of the hydraulic cylinder 6 is in the telescopic state, the top block 7 contacts the pressure plate 12, and the spring 13 is in the compressed state. At this time, the gear 15 and the rack 16 are in the separated state. When the telescopic shaft of the hydraulic cylinder 6 is extended and the aluminum cylinder 2 has not yet been inserted into the extrusion chamber 801, the spring 13 provides elastic force to move the slide rod 11 and the pressure plate 12 toward the direction of the double-chamber cylinder 8, so the push rod 14 moves synchronously, the gear 15 is engaged with the rack 16, and the gear 15 drives the rack 16 to rotate in the forward direction, and the rack 16 drives the outer ring of the one-way bearing 17 to rotate synchronously, and the inner ring of the one-way bearing 17 also rotates, and then the power is transmitted through the vertical rotation rod 18, the bevel gear 1901, the bevel gear 2 1902, the horizontal rotation rod 20, and the transmission mechanism 21 to rotate the double-chamber cylinder 8. When the gear 15 completely passes the rack 16, the double-chamber cylinder 8 rotates 180 degrees, so the two extrusion chambers 801 of the double-chamber cylinder 8 are swapped, so that the last used extrusion chamber 801 can be cleaned. When the telescopic shaft of the hydraulic cylinder 6 contracts, the gear 15 is meshed with the rack 16 again, and the gear 15 drives the rack 16 to rotate in the opposite direction, so the double-chamber cylinder 8 is no longer driven to rotate.

[0036] The frame 1 is provided with a motor 22, and a sliding seat 24 is provided on the frame 1 for rotation. The two transmission wheels of the transmission mechanism 23 are respectively installed on the end of the rotating shaft of the motor 22 and the sliding seat 24. The transmission mechanism 23 has the same working principle as the transmission mechanism 1 21. A sliding rod 25 is provided on the sliding seat 24 for sliding. A sliding rod 26 is provided on the frame 1 above the hydraulic cylinder 6. One end of the sliding rod 26 is provided with a pressure plate 27 for contacting the top block 7. The outer sleeve of 26 is provided with a spring 28, and the two ends of the spring 28 are respectively connected to the pressure plate 27 and the frame 1. The other end of the slide rod 26 is provided with a pressure plate 29 for driving the sliding rod 25. The frame 1 is provided with a spring seat 30 for inserting the sliding rod 25. The outer sleeve of the sliding rod 25 is provided with a spring 31, and the two ends of the spring 31 are respectively in contact with the spring seat 30 and the frustum in the middle of the sliding rod 25. The end of the sliding rod 25 is provided with a cleaning head 32 for cleaning the extrusion cavity 801.

[0037] Specifically, when the telescopic shaft of hydraulic cylinder 6 is in the telescopic position, top block 7 contacts pressure plate 27, spring 28 is compressed, and pressure plate 29 is separated from the end of sliding rod 25. When the telescopic shaft of hydraulic cylinder 6 extends and the dual-chamber barrel 8 rotates, spring 28 provides elastic force, causing sliding rod 26 to move toward extrusion head 10. Pressure plate 29 and sliding rod 25 begin to contact each other, driving sliding rod 25 toward dual-chamber barrel 8. Sliding rod 25 inserts spring 31 into the extrusion chamber 801 below. Power is transmitted through pressure plate 27, and motor 22 drives sliding seat 1 24 to rotate. Sliding seat 1 24 drives sliding rod 25 to rotate, which in turn drives spring 31. Therefore, spring 31 cleans the extrusion chamber 801 below, removing residual material adhered to the interior of the extrusion chamber 801 from the previous extrusion, thereby preventing surface degradation during the next extrusion.

[0038] A sliding seat 2 33 is rotatably provided on the frame 1, and the sliding seat 2 33 forms a sliding fit with the sliding rod 25; a guide wheel 34 is rotatably provided on the central table 4 and on both sides of the cleaning table 5, and the rotating shaft of the guide wheel 34 is connected to the rotating shaft 35. The two rotating wheels of the transmission mechanism 3 36 are respectively connected to the rotating shaft 35 and the sliding seat 2 33. The working principle of the transmission mechanism 3 36 is consistent with the working principle of the transmission mechanism 1 21. Grinding wheels 37 for grinding the aluminum tube 2 are provided on both sides of the cleaning table 5.

[0039] Specifically, the sliding rod 25 drives the sliding seat 2 33 to rotate, which is transmitted through the transmission mechanism 3 36 to drive the rotating shaft 35 and the two guide wheels 34 to rotate. The rotation directions of the two guide wheels 34 are consistent. When the aluminum tube 2 passes through the cleaning table 5, the aluminum tube 2 contacts the two guide wheels 34, and the guide wheels 34 drive the aluminum tube 2 to rotate, and the aluminum tube 2 rotates on the grinding wheel 37, that is, the grinding wheel 37 contacts the surface of the aluminum tube 2, and grinds off the oxide layer on the surface of the aluminum tube 2, thereby improving the quality of aluminum profile extrusion.

[0040] An inclined plate 38 is connected to the side of the unloading platform 3 on the frame 1, and two baffle rods 39 are slidably provided on the unloading platform 3 and the inclined plate 38. The lower ends of all baffle rods 39 are commonly connected to a frame 40, and a rack 2 41 is connected to the frame 40. Two baffle rods 2 42 are also slidably provided above the baffle rod 1 39 on the inclined plate 38. The lower ends of the two baffle rods 2 42 are commonly connected to a connecting rod 43, and a spring 44 is connected between the connecting rod 43 and the frame 1. A rack 3 45 is provided on the connecting rod 43, and the rack 2 41 and the rack 3 45 are symmetrically arranged. The rack 2 41 and the rack 3 45 are commonly connected to a gear 2 46, and the gear 2 46 is rotatably provided on the frame 1.

[0041] A triangular block 47 is provided below the connecting rod 43, a bevel 4701 is provided on the right-angled side of the triangular block 47, and a bevel groove 4702 is provided on the beveled side of the triangular block 47. A shift rod 48 is slidingly provided on the push rod 14 to contact the triangular block 47, and a spring 49 is connected to the shift rod 48 and the push rod 14.

[0042] Specifically, multiple aluminum tubes 2 are placed on the sloping plate 38. When the telescopic shaft of the hydraulic cylinder 6 is in the telescopic position, the lever 48 on the push rod 14 is separated from the triangular block 47. At this point, all the first stoppers 39 are in the upper position, extending above the sloping plate 38 and the aluminum tubes 2, while the second stoppers 42 are in the lower position, below the upper surface of the first stoppers 39. Therefore, the aluminum tubes 2 on the sloping plate 38 contact the first stoppers 39 on the sloping plate 38. When the telescopic shaft of the hydraulic cylinder 6 extends and the push rod 14 moves synchronously, the lever 48 on the push rod 14 contacts the inclined surface 4701, the triangular block 47 does not move, and the lever 48 slides along the inclined surface 4701, i.e., the lever 48 slides toward the outside of the push rod 14, compressing the spring 5 49. After the lever 48 passes the triangular block 47, the spring 5 49 provides an elastic force, causing the lever 48 to return to its original position. The retraction shaft of hydraulic cylinder 6 retracts, and push rod 14 moves synchronously. The lever 48 on push rod 14 contacts the inclined slot 4702, and the top of lever 48 pushes upward against the triangular block 47. Triangular block 47 moves upward synchronously with connecting rod 43 and rack 3 45. Spring 44 begins to retract, and shift lever 2 42 extends above shift lever 1 39. Spring 5 49 blocks all aluminum tubes 2 except the bottom one. Simultaneously, connecting rod 43 moves upward synchronously with rack 3 45, transmitting power through gear 2 46, causing rack 2 41 and frame 40 to move downward. As a result, all shift levers 1 39 retract to the lower position, and the bottom aluminum tube 2 moves onto the unloading platform 3. At this point, the telescopic shaft of hydraulic cylinder 6 is fully retracted, automatically completing the loading of the aluminum tube 2, facilitating operation and improving work efficiency.

[0043] The working principle of this embodiment is as follows: In the initial state, the telescopic shaft of hydraulic cylinder 6 is retracted. Ejector block 7 is in contact with pressure plate 12, spring 13 is compressed, and gear 15 is separated from rack 16. Ejector block 7 is in contact with pressure plate 27, spring 28 is compressed, and pressure plate 29 is separated from the end of sliding rod 25. Multiple aluminum tubes 2 are placed on sloping plate 38. The lever 48 on push rod 14 is separated from the triangular block 47. All stop bars 1 39 are in the upper position, extending above sloping plate 38 and the aluminum tubes 2. Stop bar 2 42 is in the lower position, below the upper surface of stop bar 1 39. Therefore, the aluminum tubes 2 on sloping plate 38 are in contact with stop bar 1 39 on sloping plate 38.

[0044] Start the hydraulic cylinder 6 to extend the telescopic shaft of the hydraulic cylinder 6, and the telescopic shaft of the hydraulic cylinder 6 drives the top block 7 to move toward the double-cavity cylinder 8, so the top block 7 pushes the aluminum tube 2 to move along the unloading table 3 and the cleaning table 5 toward the double-cavity cylinder 8. In the first stage of the movement of the top block 7 and the aluminum cylinder 2 toward the double-cavity cylinder 8, the spring 13 provides elastic force to move the slide bar 11 and the pressure plate 12 toward the double-cavity cylinder 8, so the push rod 14 moves synchronously. At this stage, the gear 15 is engaged with the rack 16, and the gear 15 drives the rack 16 to rotate in the forward direction. The rack 16 drives the outer ring of the one-way bearing 17 to rotate synchronously, and the inner ring of the one-way bearing 17 also rotates. The power is then transmitted through the vertical rotation rod 18, the bevel gear 1901, the bevel gear 2 1902, the horizontal rotation rod 20, and the transmission mechanism 21 to rotate the double-cavity cylinder 8. When the gear 15 completely passes the rack 16, the double-cavity cylinder 8 rotates 180 degrees, so the two extrusion chambers 801 of the double-cavity cylinder 8 are swapped, so that the last used extrusion chamber 801 can be cleaned. At the same time, at this stage, the lever 48 on the push rod 14 contacts the inclined surface 4701, the triangular block 47 does not move, and the lever 48 slides along the inclined surface 4701, that is, the lever 48 slides toward the outside of the push rod 14, and the spring five 49 is compressed. After the lever 48 passes the triangular block 47, the spring five 49 provides elastic force to restore the lever 48 to its original state.

[0045] During the second stage of movement of the top block 7 and the aluminum cylinder 2 toward the dual-cavity cylinder 8, spring 28 provides elastic force, causing slide rod 26 to move toward the extrusion head 10. The pressure plate 29 begins to contact the sliding rod 25, which drives the sliding rod 25 toward the dual-cavity cylinder 8. The sliding rod 25 inserts spring 31 into the lower extrusion cavity 801. Power is transmitted through pressure plate 27, and the motor 22 drives the sliding seat 1 24 to rotate. The sliding seat 1 24 drives the sliding rod 25 to rotate, and the sliding rod 25 drives the spring 31 to rotate. Therefore, spring 31 cleans the lower extrusion cavity 801, removing the residual material adhered to the interior of the extrusion cavity 801 from the previous extrusion, thereby preventing the surface quality from being degraded during the next extrusion. At the same time, during this stage, the aluminum tube 2 passes through the cleaning table 5, and the sliding rod 25 drives the sliding seat 2 33 to rotate, which is transmitted through the transmission mechanism 3 36, driving the rotating shaft 35 and the two guide wheels 34 to rotate. The rotation directions of the two guide wheels 34 are consistent, and the aluminum tube 2 contacts the two guide wheels 34. The guide wheels 34 drive the aluminum tube 2 to rotate, and the aluminum tube 2 rotates on the grinding wheel 37, that is, the grinding wheel 37 contacts the surface of the aluminum tube 2, grinding off the oxide layer on the surface of the aluminum tube 2, thereby improving the quality of the aluminum profile extrusion. In the third stage of the movement of the top block 7 and the aluminum tube 2 toward the double-cavity tube 8, the top block 7 pushes the aluminum tube 2 into the upper extrusion cavity 801, and the double-cavity tube 8 then passes through the extrusion head 10. The top block 7 applies extrusion force to the aluminum tube 2, and the extrusion cavity 801 limits the aluminum tube 2. What is extruded from the extrusion head 10 is the extruded aluminum profile.

[0046] After the aluminum tube 2 is completely extruded, hydraulic cylinder 6 is activated in the reverse direction, causing its telescopic shaft to retract. When gear 15 re-engages with rack 16, gear 15 drives rack 16 in the reverse direction, thus no longer driving the dual-chamber cylinder 8. When lever 48 on push rod 14 contacts slanted slot 4702, the top of lever 48 pushes against triangular block 47 and moves upward. Triangular block 47 moves connecting rod 43 and rack 3 45 synchronously upward, causing spring 44 to contract, and shift lever 2 42 to extend above shift lever 1 39. Spring 5 49 blocks all aluminum tubes 2 except the bottommost one. At the same time, the connecting rod 43 moves upward synchronously with the rack three 45, and transmits power through the gear two 46, so that the rack two 41 and the frame 40 move downward, so all the blocking rods 39 are retracted to the lower position, so the aluminum tube 2 at the bottom moves to the unloading table 3. At this time, the telescopic shaft of the hydraulic cylinder 6 is in a completely retracted state, so the loading of the aluminum tube 2 is automatically completed, which is convenient for operation and improves work efficiency.

[0047] Example 2: Based on the specific example 1, the difference of this example is that: The tail stage 9 is provided with a cutting frame 50, the cutting frame 50 is provided with an electric cylinder 51, the telescopic shaft end of the electric cylinder 51 is provided with a moving seat 52, the moving seat 52 is provided with a motor 53, and the rotating shaft end of the motor 53 is provided with a cutting disc 54 for cutting aluminum.

[0048] A sub-plate 55 is provided on the telescopic shaft of the electric cylinder 51, and a guide rod 56 is slidably provided at the end of the sub-plate 55, and a pressure rod 57 is provided at the lower end of the guide rod 56. A spring six 58 is sleeved on the outer sleeve of the guide rod 56, and the two ends of the spring six 58 are respectively connected to the sub-plate 55 and the pressure rod 57. A rack four 59 is connected to the bottom of the pressure rod 57, and the rack four 59 is slidably provided on the frame 1. The side of the rack four 59 is engaged with a gear three 60, and the gear three 60 is fixed on the connecting shaft 61. Two swivel seats 62 are provided on the tail stage 9, and a support frame 63 for lifting aluminum materials is provided on the support frame 63 that rotates together. The connecting shaft 61 is connected to a rotating shaft of the swivel seat 62, and the connecting shaft 61 is also provided with a baffle 64 for blocking the support frame 63.

[0049] Specifically, when the aluminum profile extruded from the extrusion head 10 is long enough, the extrusion head 10 needs to be cut. The motor 53 drives the cutting disc 54 to rotate, starting the electric cylinder 51, and the telescopic shaft of the electric cylinder 51 extends. The telescopic shaft of the electric cylinder 51 drives the moving seat 52 to move downward. The telescopic shaft of the electric cylinder 51 moves synchronously with the auxiliary plate 55. The power is transmitted by the spring six 58. The auxiliary plate 55 moves downward synchronously with the guide rod 56, the pressure rod 57 and the rack four 59. The power is then transmitted by the gear three 60, so that the connecting shaft 61 and the support frame 63 rotate synchronously on the rotating seat 62. When the support frame 63 rotates 90 degrees, the support frame 63 contacts the baffle 64. At this time, the support frame 63 no longer rotates and contacts the aluminum profile. When the telescopic shaft of the electric cylinder 51 continues to extend, the spring six 58 begins to compress, and the support frame 63 no longer rotates. The support frame 63 holds the aluminum profile, making it easier for the cutting disc 54 to cut the aluminum profile, making the cut more even.

Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
