Description

Technical Field

[0001] The present invention relates to the technical field of sandblasting equipment, and specifically relates to a trimming mechanism for the surface of aluminum profiles and a trimming method therefor. Background Art

[0002] During the production and processing of aluminum profiles, the surfaces of some aluminum profiles are trimmed as needed. The trimming includes grinding, polishing, and sandblasting processes. Among them, the purpose of sandblasting is to improve the physical properties of the surface of aluminum profiles to facilitate subsequent coating operations on the surface of aluminum profiles.

[0003] During the sandblasting process, first, the aluminum profiles are cleaned to remove impurities and oil stains on the surface. Then, the aluminum profiles are placed on the sandblasting equipment. After the staff transports the aluminum profiles into the equipment, sandblasting work is carried out. Before sandblasting, it is necessary to adjust the sandblasting equipment, such as sandblasting air pressure, sandblasting distance, and sandblasting angle. After the adjustment is completed, sandblasting operations can be started. After sandblasting, the aluminum profiles are taken out and then subsequent spraying treatment is carried out.

[0004] In the prior art, when transporting aluminum profiles into the sandblasting equipment for sandblasting, since most aluminum profiles are square structures, only the surface can be sandblasted during operation. After the surface facing the spraying head is sandblasted, the staff takes out the aluminum profile and flips it, and then puts it into the sandblaster again for secondary sandblasting. This taking out and putting in increases the sandblasting steps. And during sandblasting, it is necessary for the staff to transport the aluminum profiles into the sandblaster. However, for a large number of trimming operations, the staff cannot transport multiple groups of aluminum profiles at the same time. Moreover, during large-scale sandblasting operations, if the aluminum profiles are stuck together, it will also affect the trimming quality of the aluminum profiles, resulting in a reduction in work efficiency and an increase in the labor intensity of the staff. After both sides are sandblasted, the staff also needs to clean the abrasive residues on the surface of the aluminum profiles and finally stack them. Summary of the Invention

[0022] A method for finishing the surface of aluminum profiles includes the following steps:

[0023] S1. First, place the workpiece body on the supporting bars in sequence, and then drive the conveying lead screw to drive the supporting bars to reach the feeding rollers. During the conveying process, the supporting bars slowly descend, and during the descending process, the workpiece body is received by the feeding rollers. Then drive the feeding rollers to rotate to convey the workpiece body into the sandblasting chamber for sandblasting.

[0024] S2. When the workpiece body is conveyed by the feeding rollers, it will reach the limiting plates. After being regularized by the limiting plates, the workpiece body enters the sandblasting chamber. After sandblasting by the sandblasting device, the linear motor drives the flipping chamber to descend. Use the flipping plates to clamp and flip the workpiece body, and then perform sandblasting on the other side.

[0025] S3. After sandblasting, convey the workpiece body out by the sandblasting rollers, and then reach the discharging plate. Then clamp and fix the workpiece body by the clamping plates, and then drive the telescopic cylinder to raise the discharging plate to make the discharging plate inclined with the workpiece body. After inclination, the abrasive remaining on the surface of the workpiece body will slide to the waste opening and finally reach the waste box for collection.

[0026] Advantages of the present invention:

[0027] (1) In the present invention, the workpiece bodies are placed on the supporting bars in groups, and then the conveying screw rod is driven to rotate. When rotating, the conveying screw rod will drive the two conveying blocks to move towards the feeding rollers on the feeding rack. During the movement, the tensioning strip on the side wall of the supporting bar will contact the inclined plate on the side wall of the feeding rack. The inclined plate is arranged from high to low, and at the same time, the tensioning strip is arranged below the inclined plate. When the tensioning strip contacts the inclined plate, the tensioning strip will be squeezed by the inclined plate. As the conveying block moves, the tensioning strip will drive the supporting bar to continuously descend, and at the same time, squeeze the sliding column and the telescopic spring. During the descent of the supporting bar, the workpiece body will also descend. Finally, the supporting bar will descend below the feeding rollers. At this time, the workpiece body is received by the feeding rollers, and then the feeding rollers are driven to convey the workpiece body into the sandblasting chamber.

[0028] (2) When one side of the workpiece body is sandblasted, the linear motor drives the telescopic rod to descend, so that the flipping chamber descends to be parallel to the workpiece body. Subsequently, the connecting screw rod is driven to rotate, and the two flipping plates are driven by the connecting screw rod to clamp the workpiece body. Then, the flipping motor drives the flipping chamber to rotate to flip the workpiece body for sandblasting on the other side. At the same time, the number of linear motors is the same as that of the limiting plates, and linear motors are arranged at both ends of the sandblasting chamber, and the two ends of the workpiece body can be clamped and flipped simultaneously. And the connecting screw rods are all driven by motors, and the motors are not shown in the figure. Through the setting of the linear motor, the workpiece body can be quickly flipped, which is convenient for comprehensive sandblasting of the workpiece body.

[0029] (3) After the sandblasting work is completed, the sandblasting roller conveys the workpiece body out of the sandblasting chamber and reaches the discharge plate. The discharge plate receives the workpiece body. Subsequently, the fixed screw rod in the fixed chamber rotates, and when rotating, it drives the clamping plate to clamp and fix the workpiece body. The working mode of the clamping plate and the fixed screw rod is the same as that of the front limiting plate. After clamping the workpiece body, the telescopic cylinder is started to lift the discharge plate, so that the discharge plate is inclined with the workpiece body. After tilting, the residual sand and impurities on the workpiece body will slide to the waste outlet and reach the waste box. Through the setting of the discharge base and the discharge plate, the residual abrasive on the workpiece body can be quickly removed. Description of the Drawings

Detailed Description of the Invention

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figures 1 - 12 As shown, the present application provides a trimming mechanism for the surface of aluminum profiles, including a sandblasting chamber 1 and a workpiece body 3: It further includes:

[0046] A feeding mechanism 2, arranged on one side of the sandblasting chamber 1, for feeding the workpiece body 3;

[0047] A conveying mechanism 4, connected to the feeding mechanism 2, for conveying the workpiece body 3 to the feeding mechanism 2 for feeding;

[0048] A discharging mechanism 5, arranged at the other end of the sandblasting chamber 1, for discharging the workpiece body 3;

[0049] A limiting mechanism 6, arranged between the feeding mechanism 2 and the sandblasting chamber 1, for limiting the workpiece body 3;

[0050] A flipping mechanism 9, arranged inside the sandblasting chamber 1, for flipping the workpiece body 3;

[0051] A sandblaster 11 is fixedly connected to the top of the sandblasting chamber 1; a sandblasting roller 12 is rotatably connected to the side wall of the sandblasting chamber 1; the sandblasting roller 12 is arranged below the sandblaster 11; a blanking plate 13 and a diversion plate 14 are fixedly connected to the side wall of the sandblasting chamber 1; the diversion plate 14 is arranged below the blanking plate 13; a collection chamber 16 is fixedly connected to the bottom of the sandblasting chamber 1; curtain doors 15 are arranged on both sides of the sandblasting chamber 1;

[0052] During operation, in the prior art, when transporting aluminum profiles into the sandblasting equipment for sandblasting, since most aluminum profiles have a square structure, only the surface can be sandblasted during operation. After the side facing the spraying head is sandblasted, the staff will take out the aluminum profile and turn it over, and then put it into the sandblaster again for secondary sandblasting. This taking out and putting in increases the sandblasting steps. And during sandblasting, the staff needs to transport the aluminum profiles into the sandblaster. However, for a large number of trimming operations, the staff cannot transport multiple groups of aluminum profiles at the same time. Moreover, during large-scale sandblasting operations, if the aluminum profiles are stuck together, it will also affect the trimming quality of the aluminum profiles, resulting in a decrease in work efficiency and an increase in the workload of the staff. After both sides are sandblasted, the staff also needs to clean the abrasive residues on the surface of the aluminum profiles and finally stack them. To prevent such incidents from occurring, first, place the workpiece body 3 on the conveying mechanism 4, then use the conveying mechanism 4 to transport the workpiece body 3 to the feeding mechanism 2, and then the feeding mechanism 2 transports the workpiece body 3 into the sandblasting chamber 1. During transportation, the workpiece body 3 is also limited and regularized by the limiting mechanism 6. When the workpiece body 3 enters the sandblasting chamber 1, start the sandblaster 11 in the sandblasting chamber 1 to perform sandblasting on the workpiece body 3. During the sandblasting operation, the sprayed sand will fall on the lower blanking plate 13 below, and then fall onto the lower guide plate 14, and slide towards the lower collection bin 16 through the diversion of the guide plate 14. The sand in the collection bin 16 can be filtered and then reused. Among them, the door curtains 15 on both sides of the sandblasting chamber 1 are made of soft materials, which facilitate the entry and exit of the workpiece body 3 and prevent the internal sand and gravel from flying out.

[0053] As Figures 6 - 9 shown, the feeding mechanism 2 includes a feeding frame 21; a feeding roller 22 is rotatably connected to the side wall of the feeding frame 21; multiple groups of the feeding rollers 22 are provided; a sloping plate 211 is also fixedly connected to the side wall of the feeding frame 21; the conveying mechanism 4 includes a conveying bin 41; multiple groups of the conveying bins 41 are provided; the conveying bin 41 is fixedly connected to the side wall of the feeding frame 21; a conveying lead screw 42 is rotatably connected in the conveying bin 41; a conveying block 43 is threadedly connected to the conveying lead screw 42; two groups of the conveying blocks 43 are provided; a telescopic tube 44 is fixedly connected to the conveying block 43; a telescopic spring 441 is fixedly connected in the telescopic tube 44; one end of the telescopic spring 441 away from the conveying tube is fixedly connected to a sliding column 442; the sliding column 442 is slidably arranged in the telescopic tube 44; one end of the sliding column 442 away from the telescopic spring 441 is fixedly connected to a supporting strip 45; the supporting strip 45 is arranged higher than the feeding roller 22; the workpiece body 3 is placed on the supporting strip 45; a tensioning strip 47 is fixedly connected to the side wall of the supporting strip 45; the tensioning strip 47 is located below the sloping plate 211;

[0054] During operation, the workpiece bodies 3 are placed on the supporting bars 45 in groups, and then the conveying lead screw 42 is driven to rotate. When rotating, the conveying lead screw 42 will drive the two groups of conveying blocks 43 to move towards the feeding rollers 22 on the feeding rack 21. During the movement, the tensioning strip 47 on the side wall of the supporting bar 45 will contact the inclined plate 211 on the side wall of the feeding rack 21. The inclined plate 211 is arranged from high to low, and at the same time, the tensioning strip 47 is arranged below the inclined plate 211. When the tensioning strip 47 contacts the inclined plate 211, the tensioning strip 47 will be squeezed by the inclined plate 211. As the conveying block 43 moves, the tensioning strip 47 will drive the supporting bar 45 to continuously descend, and at the same time, squeeze the sliding column 442 and the telescopic spring 441. During the descent of the supporting bar 45, the workpiece body 3 will also descend. Finally, the supporting bar 45 will descend below the feeding roller 22. At this time, the workpiece body 3 is received by the feeding roller 22, and then the feeding roller 22 is driven to convey the workpiece body 3 into the sandblasting chamber 1. After the feeding roller 22 conveys the workpiece body 3 into the sandblasting chamber 1, the conveying lead screw 42 is driven to reverse. After reversing, it will drive the conveying block 43 and the supporting bar 45 away from the feeding roller 22. During the separation process, the tensioning strip 47 slowly moves away from the inclined plate 211, thereby releasing the pressure generated by the inclined plate 211 on the tensioning strip 47, causing the supporting bar 45 to rise, and then the workpiece body 3 is placed on the supporting bar 45 again.

[0055] As Figures 3 - 5 shown, the limiting mechanism 6 includes a limiting base 61; the limiting base 61 is fixedly connected to the side wall of the sandblasting chamber 1; the limiting base 61 is located between the sandblasting chamber 1 and the feeding rack 21; a lead screw one 611 and a lead screw two 612 are rotatably connected in the limiting base 61; the ends of the lead screw one 611 and the lead screw two 612 away from the limiting base 61 are fixedly connected with a connecting block 613; the connecting block 613 is rotatably arranged in the limiting base 61; a hexagonal notch 6131 is formed in the connecting block 613; a hexagonal column 614 is slidably arranged in the hexagonal notch 6131; a pulling plate 615 is fixedly connected to the bottom of the hexagonal column 614; movable blocks 63 are threadedly connected to the lead screw one 611 and the lead screw two 612; multiple groups of movable blocks 63 are provided; a limiting plate 64 is rotatably connected to the movable block 63; the end of the limiting plate 64 away from the movable block 63 is rotatably arranged on the limiting base 61; driving handles 62 are rotatably connected to both ends of the limiting base 61; the output ends of the driving handles 62 are fixedly connected to the input ends of the lead screw one 611 and the lead screw two 612; the limiting plate 64 is arranged below the curtain 15;

[0056] During operation, after the workpiece body 3 is conveyed to the limit base 61 by the feeding roller 22, it will be regularized by the limit plates 64 on the limit base 61. The limit plates 64 are arranged in pairs, with multiple groups, arranged in a triangular shape. The end with the larger opening faces the feeding frame 21, and the end with the smaller opening faces the sandblasting chamber 1. Before sandblasting, the limit plates 64 are adjusted first. During adjustment, the operator rotates the driving handle 62, which drives the rotation of the first screw rod 611 and the second screw rod 612 inside the limit base 61. When the first screw rod 611 and the second screw rod 612 rotate, they drive the movement of the movable block 63 connected by threads. The limit plates 64 are connected to the movable block 63, and the movable block 63 is consistent with the limit plates 64, arranged in pairs. When the first screw rod 611 and the second screw rod 612 rotate, they will drive the mirror movement of the movable blocks 63 arranged in pairs, thereby controlling the opening size of the two groups of limit plates 64. The opening size is determined according to the size of the workpiece body 3, and the limit plates 64 can be adjusted separately. For example, when two workpiece bodies 3 of different sizes are placed on the feeding roller 22, the operator will separate the hexagonal column 614 in the connecting block 613 from the other group of connecting blocks 613 through the pull plate 615. After separation, when rotating one group of driving handles 62, it will not be able to drive the movement of the limit plates 64 on the other half. Only the limit plates 64 can be adjusted through the driving handles 62 on the other half. When it is necessary to drive them simultaneously, then connect the hexagonal column 614 with the two groups of connecting blocks 613. After the opening size is adjusted, when the feeding roller 22 conveys the workpiece body 3, the workpiece body 3 will be guided by the limit plates 64 and thus enter the sandblasting chamber 1 regularly for sandblasting work.

[0057] As Figure 2 and Figure 12 As shown, the flipping mechanism 9 includes a linear motor 91; the linear motor 91 is fixedly connected to the inner wall of the sandblasting chamber 1; multiple groups of the linear motors 91 are provided and are arranged corresponding to the limit plates 64; one end of the linear motor 91 is slidably provided with a telescopic rod 92; the end of the telescopic rod 92 away from the linear motor 91 is fixedly connected to a rotating motor 93; the side wall of the rotating motor 93 is rotatably connected to a flipping chamber 94; a connecting screw rod 95 is rotatably connected inside the flipping chamber 94; a flipping plate 96 is threadedly connected to the connecting screw rod 95; two groups of the flipping plates 96 are provided;

[0058] During operation, when sandblasting on one side of the workpiece body 3 is completed, the linear motor 91 drives the telescopic rod 92 to descend, causing the flipping bin 94 to descend to be parallel to the workpiece body 3. Subsequently, the connecting lead screw 95 is driven to rotate, and the two groups of flipping plates 96 are driven by the connecting lead screw 95 to clamp the workpiece body 3. Then, the flipping bin 94 is driven to rotate by the flipping motor, causing the workpiece body 3 to flip for sandblasting on the other side. At the same time, the number of linear motors 91 is the same as that of the limit plates 64, and linear motors 91 are provided at both ends of the sandblasting bin 1, enabling clamping and flipping of both ends of the workpiece body 3 simultaneously. Moreover, the connecting lead screws 95 are all driven by motors, and the motors are not shown in the figure. Through the setting of the linear motor 91, the workpiece body 3 can be quickly flipped, facilitating full sandblasting of the workpiece body 3.

[0059] As Figure 10 and Figure 11 shown, the discharging mechanism 5 includes a discharging base 51; a telescopic cylinder 512 and a hinged plate 513 are fixedly connected to the discharging base 51; one end of the telescopic cylinder 512 away from the discharging base 51 is fixedly connected to a discharging plate 52; one end of the discharging plate 52 away from the telescopic cylinder 512 is hinged to the hinged plate 513; a fixed bin 53 is fixedly connected to the discharging plate 52; a fixed lead screw 531 is rotatably connected inside the fixed bin 53; a clamping plate 532 is threadedly connected to the fixed lead screw 531; multiple groups of clamping plates 532 are provided and are arranged corresponding to the limit plates 64; a waste opening 511 is formed at the bottom of the discharging base 51; a waste bin 7 is provided below the waste opening 511.

[0060] During operation, after the sandblasting work is completed, the sandblasting roller 12 conveys the workpiece body 3 out of the sandblasting bin 1 and reaches the discharging plate 52. After being received by the discharging plate 52, the fixed lead screw 531 inside the fixed bin 53 rotates, and when rotating, it drives the clamping plate 532 to clamp and fix the workpiece body 3. The working mode of the clamping plate 532 and the fixed lead screw 531 is the same as that of the front limit plate 64. After clamping the workpiece body 3, the telescopic cylinder 512 is started to lift the discharging plate 52, making the discharging plate 52 inclined with the workpiece body 3. After inclination, the remaining sand and impurities on the workpiece body 3 will slide to the waste opening 511 and reach the waste bin 7. Through the setting of the discharging base 51 and the discharging plate 52, the abrasive remaining on the workpiece body 3 can be quickly removed.

[0061] As Figure 6 and Figure 10 shown, a conveying motor 46 is fixedly connected to the side wall of the conveying bin 41; the conveying lead screw 42 is driven by the conveying motor 46; a fixed motor 54 is fixedly connected to the side wall of the fixed bin 53; the fixed lead screw 531 is driven by the fixed motor 54.

[0062] During operation, the conveying motor 46 can convey the workpiece body 3 onto the feeding roller 22, and the fixing motor 54 drives the clamping plate 532 to fix the workpiece body 3.

[0063] As Figure 1 shown, a sand storage bin 8 is fixedly connected to the top of the sandblasting chamber 1; a sand inlet pipe 81 is fixedly connected to the sand storage bin 8;

[0064] During operation, the sand storage bin 8 can store sand and gravel, and materials can be fed into the sand storage bin 8 through the sand inlet pipe 81.

[0065] Please refer to Figures 1 - 12 shown, the present application provides a trimming method for the surface of aluminum profiles, including the following steps:

[0066] S1. First, place the workpiece body 3 on the supporting strip 45 in sequence, then drive the conveying lead screw 42 to drive the supporting strip 45 to reach the feeding roller 22. During the conveying process, the supporting strip 45 slowly descends, and the workpiece body 3 is received by the feeding roller 22 during the descending process. Then drive the feeding roller 22 to rotate to convey the workpiece body 3 into the sandblasting chamber 1 for sandblasting;

[0067] S2. When the workpiece body 3 is conveyed by the feeding roller 22, it will reach the limiting plate 64. After being regularized by the limiting plate 64, it enters the sandblasting chamber 1. After being sandblasted by the sandblasting device 11, the linear motor 91 drives the flipping chamber 94 to descend, clamps the workpiece body 3 with the flipping plate 96 and then flips it, and then performs sandblasting on the other side;

[0068] S3. After sandblasting, the workpiece body 3 is conveyed out by the sandblasting roller 12, then reaches the discharge plate 52, and then is clamped and fixed by the clamping plate 532. Then drive the telescopic cylinder 512 to raise the discharge plate 52 to make the discharge plate 52 inclined with the workpiece body 3. After inclination, the abrasive residues on the surface of the workpiece body 3 will slide to the waste outlet 511 and finally reach the waste box 7 for collection;

[0069] During operation, first, the workpiece body 3 is successively placed on the supporting bars 45. Subsequently, the conveying lead screw 42 is driven to drive the supporting bars 45 to reach the feeding roller 22. During the conveying process, the supporting bars 45 slowly descend. During the descending process, the workpiece body 3 is received by the feeding roller 22. Subsequently, the feeding roller 22 is driven to rotate to convey the workpiece body 3 into the sandblasting chamber 1 for sandblasting. When the workpiece body 3 is conveyed by the feeding roller 22, it will reach the limiting plate 64. After being regularized by the limiting plate 64, the workpiece body 3 enters the sandblasting chamber 1. The sandblaster 11 performs sandblasting on it. After sandblasting is completed, the linear motor 91 drives the flipping chamber 94 to descend. The workpiece body 3 is clamped and flipped by the flipping plate 96, and then sandblasting on the other side is carried out. After sandblasting is completed, the workpiece body 3 is conveyed out by the sandblasting roller 12 and then reaches the discharging plate 52. Subsequently, the workpiece body 3 is clamped and fixed by the clamping plate 532. Then, the telescopic cylinder 512 is driven to raise the discharging plate 52, making the discharging plate 52 inclined with respect to the workpiece body 3. After inclination, the abrasive remaining on the surface of the workpiece body 3 will slide to the waste outlet 511 and finally reach the waste box 7 for collection.

[0070] The working principle of the present invention: First, the workpiece body 3 is successively placed on the supporting bars 45. Subsequently, the conveying lead screw 42 is driven to drive the supporting bars 45 to reach the feeding roller 22. During the conveying process, the supporting bars 45 slowly descend. During the descending process, the workpiece body 3 is received by the feeding roller 22. Subsequently, the feeding roller 22 is driven to rotate to convey the workpiece body 3 into the sandblasting chamber 1 for sandblasting. When the workpiece body 3 is conveyed by the feeding roller 22, it will reach the limiting plate 64. After being regularized by the limiting plate 64, the workpiece body 3 enters the sandblasting chamber 1. The sandblaster 11 performs sandblasting on it. After sandblasting is completed, the linear motor 91 drives the flipping chamber 94 to descend. The workpiece body 3 is clamped and flipped by the flipping plate 96, and then sandblasting on the other side is carried out. After sandblasting is completed, the workpiece body 3 is conveyed out by the sandblasting roller 12 and then reaches the discharging plate 52. Subsequently, the workpiece body 3 is clamped and fixed by the clamping plate 532. Then, the telescopic cylinder 512 is driven to raise the discharging plate 52, making the discharging plate 52 inclined with respect to the workpiece body 3. After inclination, the abrasive remaining on the surface of the workpiece body 3 will slide to the waste outlet 511 and finally reach the waste box 7 for collection.

[0071] Among them, the workpiece bodies 3 are placed on the supporting strips 45 group by group, and then the conveying lead screw 42 is driven to rotate. When rotating, the conveying lead screw 42 will drive the two conveying blocks 43 to move towards the feeding rollers 22 on the feeding frame 21. During the moving process, the tensioning strips 47 on the side wall of the supporting strip 45 will contact the inclined plate 211 on the side wall of the feeding frame 21. The inclined plate 211 is arranged from high to low, and at the same time, the tensioning strip 47 is arranged below the inclined plate 211. When the tensioning strip 47 contacts the inclined plate 211, the tensioning strip 47 will be squeezed by the inclined plate 211. As the conveying block 43 moves, the tensioning strip 47 will drive the supporting strip 45 to continuously descend, and at the same time, squeeze the sliding column 442 and the telescopic spring 441. During the descending process of the supporting strip 45, the workpiece body 3 will also descend. Finally, the supporting strip 45 will descend below the feeding roller 22. At this time, the workpiece body 3 is received by the feeding roller 22, and then the feeding roller 22 is driven to convey the workpiece body 3 into the sandblasting chamber 1. After the feeding roller 22 conveys the workpiece body 3 into the sandblasting chamber 1, the conveying lead screw 42 is driven to reverse. After reversing, it will drive the conveying block 43 and the supporting strip 45 to move away from the feeding roller 22. During the moving away process, the tensioning strip 47 slowly moves away from the inclined plate 211, thereby releasing the pressure generated by the inclined plate 211 on the tensioning strip 47, causing the supporting strip 45 to rise, and then the workpiece body 3 is placed on the supporting strip 45 again.

All equal changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
