[0001] This utility model relates to the field of shot blasting machines, specifically to a shot blasting machine steel shot recovery device and a shot blasting machine. Background Technology

[0002] Some aluminum alloy profiles require shot blasting before oxidation. This process facilitates the formation of an oxide film and the small pits created by shot blasting mask the metallic luster of the profile surface, resulting in a matte finish and preventing light pollution. However, after shot blasting, some steel shot is carried out of the aluminum alloy profile by the shot. Some manufacturers use specialized equipment to tilt and shake the profile to return the steel shot to the shot blasting machine. This method is inefficient, disrupts continuous production, and results in poor recycling. Utility Model Content

[0018] <Overall Structure>

[0019] like Figure 1-3 As shown, this utility model provides a shot blasting machine steel shot recovery device, which includes a shot blasting machine 100, a one-way door structure 200, a conveying mechanism 300, a steel shot interception device 400, and an aluminum alloy profile 500.

[0020] The shot blasting machine 100 includes a shot blasting chamber 101, a steel shot recovery inlet 102, a ramp 103, and a baffle 104.

[0021] The inner chamber 101 of the shot blasting machine is only shown in the figure. Its function is to allow the surface of the aluminum alloy profile 500 to be densely blasted by steel shot inside the shot blasting machine 100.

[0022] The steel shot recovery inlet 102 is rectangular and located on the lower right side of the shot blasting machine 100.

[0023] The ramp 103 is located on the right side of the steel shot recovery inlet 102. The proximal side of the ramp 103 is connected to the steel shot recovery inlet 102. The ramp 103 and the steel shot recovery inlet 102 are arranged at a predetermined angle to facilitate the recovery of steel shot.

[0024] The baffle 104 is located on the far end of the ramp 103 and is arranged parallel to the steel shot recovery inlet 102.

[0025] The one-way door structure 200 includes a one-way door 201, a "[" shaped structure 202, a connecting rod 203, a cylindrical structure 204, a cylindrical groove 205, and a horizontal block 206.

[0026] A one-way door 201 is positioned close to the left side of the shot blasting inlet 102, parallel to the baffle 104, to allow shot to be recycled into the shot blasting machine chamber 101 in one direction. A "["-shaped structure 202 is connected at one end to the one-way door 201 and at the other end to a connecting rod 203. A cylindrical structure 204 is connected below the connecting rod 203. Cylindrical grooves 205 are distributed on the upper left side of the horizontal block 206, into which the cylindrical structure 204 can be inserted. The diameter of the cylindrical grooves 205 is slightly larger than that of the cylindrical structure 204. The right side of the horizontal block 206 is perpendicular to and connected to the side wall 105 of the shot blasting machine 100.

[0027] Thus, the one-way door 201 can pivot and open the steel shot recovery inlet 102 when subjected to the impact force of steel shot rolling down from the ramp 103 via the pivot mechanism formed between the cylindrical structure 204 below the connecting rod 203 and the cylindrical groove 205 in the cross block 206.

[0028] The conveying mechanism 300 includes a support 301, a roller 302, and a drive roller 303. The roller 302 rests within an arcuate structure at the top of the support 301. The outer side of the roller 302 is a cylindrical drive roller 303. The aluminum alloy profile 500 can move on the conveying mechanism 300. Thus, the drive roller 303 is rotatably supported on the support 301 via the roller 302, conveying the aluminum alloy profile from the profile outlet 106 downstream after passing over the drive roller 303.

[0029] The profile outlet 106 of the shot blasting machine 100 is the outlet for the aluminum alloy profile 500 after shot blasting, and is located above the steel shot recovery inlet 102.

[0030] The steel shot interception device 400 includes sensing device I 401, sensing device II 402, upper electromagnetic device 403, and lower electromagnetic device 404.

[0031] Both sensor I 401 and sensor II 402 are photosensitive elements. When the photosensitive element emits a light beam, the light beam will be reflected back when the aluminum alloy profile 500 passes by. When the aluminum alloy profile 500 is not present, the light beam will not be reflected back.

[0032] The upper electromagnetic device 403 is positioned above the aluminum alloy profile 500 and at a short distance. From a vertical perspective, the upper electromagnetic device 403 is above the transmission roller 303 and between adjacent transmission rollers 303.

[0033] The lower electromagnetic device 404 consists of three parts: a lower electromagnetic side part 405, a lower electromagnetic side part 406, and a rotating shaft 407. The rotating shaft 407 is controlled by a servo motor, which allows the lower electromagnetic side part 405 and the lower electromagnetic side part 406 to interchange positions. Preferably, the lower electromagnetic side part 405 and the lower electromagnetic side part 406 are arranged on opposite sides of the rotating shaft 407. In order for the steel shot to fall smoothly onto the ramp 103 after power is cut off, during operation, the steel shot is attracted to the lower electromagnetic side part 405 above the lower electromagnetic device 404. After the aluminum alloy profile 500 passes through the induction device II 402, the rotating shaft 407 rotates 180°, rotating the lower electromagnetic side part 405 to the bottom. Then the lower electromagnetic device 404 is de-energized, and the steel shot falls onto the ramp 103.

[0034] From the perspective of vertical distribution, the lower electromagnetic device 404 is arranged below the transmission roller 303 and between adjacent transmission rollers 303.

[0035] From a front-to-back distribution perspective, the upper electromagnetic device 403 and the lower electromagnetic device 404 are arranged in two pairs, alternating with each other, along the upstream and downstream directions of the conveying mechanism 300. However, this is not a limitation; one or more pairs or multiple pairs may also be arranged.

[0036] The sensing device I401 is installed at the profile outlet 106 of the shot blasting machine 100, on the lateral side of the conveying mechanism 300, and on the same horizontal plane as the aluminum alloy profile 500.

[0037] The sensing device II 402 is located downstream of the second lower electromagnetic device 404, on the transverse side of the conveying mechanism 300, and on the same horizontal plane as the aluminum alloy profile 500.

[0038] There are two sets of upper electromagnetic devices 403 and two sets of lower electromagnetic devices 404. When the first set of upper electromagnetic devices 403 and lower electromagnetic devices 404 cannot completely attract the steel shot, the second set of upper electromagnetic devices 403 and lower electromagnetic devices 404 downstream will play a supplementary role. Figure 2 As shown, the upper electromagnetic device 403 and the lower electromagnetic device 404 are generally elongated, and their extension range covers all the aluminum alloy profiles 500 that are conveyed side by side on the conveying mechanism 300.

[0039] Thus, according to this utility model, a shot blasting machine shot recovery device is provided for recovering shot from aluminum alloy profiles 500 conveyed downstream from the shot blasting machine via a conveying mechanism 300. The device includes: sensing devices I 401 and II 402 respectively disposed on the upstream and downstream sides of the conveying mechanism 300 for sensing the head and tail ends of the aluminum alloy profiles 500; an upper electromagnetic device 403 and a lower electromagnetic device 404 respectively disposed on the upper and lower sides of the conveying mechanism 300 between adjacent transmission rollers 303 of the corresponding conveying mechanism 300; the lower electromagnetic device 404 includes a lower electromagnetic side portion 405 and a lower electromagnetic side portion 406 connected via a rotating shaft 407 and capable of being swapped in position by rotating the rotating shaft 407; when energized, the upper electromagnetic device 403 and the lower electromagnetic side portion 405 and the lower electromagnetic side portion 406 can attract the shot carried by the aluminum alloy profiles 500.

[0040] <Example>

[0041] from Figure 1 See, each set of upper electromagnetic devices 403 and lower electromagnetic devices 404 are arranged in a front-to-back manner, with a distance of 500-600mm between them to prevent electromagnetic interference. The bottom of the upper electromagnetic device 403 is 20-30mm away from the top of the aluminum alloy profile 500, and the top of the lower electromagnetic device 404 is 15-20mm away from the bottom of the aluminum alloy profile 500.

[0042] from Figure 3 See, the sensor I 401 and sensor II 402 are located on the side of the profile, with a distance of 200-300mm between them.

[0043] The slope 103 has an inclination angle of 15°-16°, with the side closer to the baffle 104 being higher and the side closer to the steel shot recovery inlet 102 being lower.

[0044] The baffle 104 has a height of 500 (±5) mm and a thickness of 20 (±1) mm.

[0045] The one-way gate structure 200 only allows steel shot to enter the shot blasting machine chamber from the ramp 103, preventing steel shot from exiting the shot blasting machine chamber 101. The steel shot recovery inlet 102 is 200 (±1) mm high. The one-way gate 201 is 300 (±1) mm high and 5 (±0.5) mm thick, completely covering the side of the steel shot recovery inlet 102 closest to the shot blasting machine chamber 101. The cylindrical structure 204 has a diameter of 20 (±0.05) mm. The cylindrical groove 205 has a diameter of 21 (±0.05) mm and an arc angle of 120°-125°.

[0046] <Action Example>

[0047] After the aluminum alloy profile 500 exits the shot blasting machine 100, it is conveyed forward by the conveying mechanism 300. The end of the aluminum alloy profile 500 is first sensed by the sensing device I 401. After the control system receives the signal, it energizes the upper electromagnetic device 403 and the lower electromagnetic device 404. As the aluminum alloy profile 500 passes through, the steel shot carried out from the surface of the aluminum alloy profile 500 and the steel shot inside the cavity are affected by the magnetic field. The steel shot on the surface will be attracted to the upper electromagnetic device 403 and the lower electromagnetic device 404; the steel shot inside the cavity will also be affected by the magnetic field and stay below the upper electromagnetic device 403 or above the lower electromagnetic device 404, and will not move forward with the aluminum alloy profile 500. After the tail end of the aluminum alloy profile 500 is removed from the magnetic field, the steel shot will be further attracted by the upper electromagnetic device 403 and the lower electromagnetic device 404.

[0048] When the tail end of the aluminum alloy profile 500 moves out of the sensing range of the sensing device II 402, the upper electromagnetic device 403 is de-energized, and the captured steel shot falls onto the ramp 103; the lower electromagnetic device 404 first rotates 180° around the rotating shaft 407, and then is de-energized, and the captured steel shot falls onto the ramp 103. These steel shots roll down the ramp 103 to the steel shot recovery inlet 102, pass through the one-way door 201 mechanism, and return to the shot blasting machine chamber 101.

[0049] This process is repeated to recover the steel shot.

[0050] The above examples illustrate the paired upper electromagnetic device 403 and lower electromagnetic device 404, but are not limited thereto. In addition to the upstream pair, one can also be provided separately or individually on the downstream side.
