Description

Technical Field

[0001] This utility model relates to a surface treatment device, specifically a surface treatment device for a loudspeaker T-iron, and belongs to the technical field of surface treatment devices. Background Technology

[0002] The speaker's T-iron is the core magnetic conductor in the speaker's magnetic circuit system. T-shaped, it is mounted at the bottom of the speaker frame, forming a closed magnetic circuit with the magnet and washer. Its core function is to concentrate the magnetic field into the magnetic gap, improving magnetic field utilization and speaker sensitivity, and providing stable power for the voice coil vibration. During production, a sandblasting device is often used for surface treatment to remove surface impurities, improve surface adhesion, and optimize magnetic circuit contact. Sandblasting ensures the T-iron achieves the required surface cleanliness and roughness, guaranteeing the structural stability of the magnetic circuit system and improving magnetic field utilization, indirectly enhancing the speaker's sensitivity and lifespan.

[0003] However, traditional sandblasting equipment typically transports the T-iron to the sandblasting chamber via a conveyor when sandblasting the surface of a speaker. Multiple spray guns inside the chamber mix abrasive with compressed air to form a high-speed jet that impacts the T-iron surface, achieving the effects of rust removal, deburring, and surface roughening. After sandblasting, the T-irons are usually directly transported to the end of the conveyor and picked up manually one by one or dropped directly into a turnover box. Because the platform is high, direct dropping can easily cause the T-irons to deform or scratch. Moreover, manual picking is inefficient. In addition, abrasive residue remains on the surface of the sandblasted T-irons, which can easily slip onto the ground when picked up manually, making it difficult to clean and lacking flexibility. Utility Model Content

[0004] The purpose of this invention is to provide a surface treatment device for speaker T-irons to solve the above-mentioned problems. By installing an inclined filter screen at the end of the conveyor and an air blowing strip above the filter screen, it is easy to blow away the abrasive residue on the T-irons. The lifting and lowering of the tray and the storage box are controlled by a screw, so that the sandblasted T-irons can be stored in the storage box. This solves the problem that the T-irons may fall directly and be deformed and damaged due to the high platform.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a surface treatment device for a speaker T-iron, comprising a sandblasting machine body, a feeding structure on the sandblasting machine body, the feeding structure including guide rods, two guide rods fixedly connected to the end of the sandblasting machine body, a bracket slidably connected between the two guide rods, a lead screw parallel to the two guide rods, a threaded connection between the bracket and the lead screw, a storage box engaged on the bracket, a mounting frame above the bracket, the mounting frame fixedly connected to the sandblasting machine body, an air blowing strip fixedly connected to the top of the mounting frame, a filter screen fixedly connected to the inner side of the mounting frame, the top of the filter screen abutting against the sandblasting machine body, and the bottom of the filter screen abutting against the storage box.

[0007] Preferably, a storage box is provided below the filter screen, the storage box is engaged with the inner side of the mounting bracket, the bottom surface of the storage box is slidably connected to the mounting plate, and the outer surface of the storage box abuts against the storage box.

[0008] Preferably, a knob is threaded to the outer end of the bracket, and the end of the knob abuts against the storage box.

[0009] Preferably, the air blowing strip has an inclined groove inside, and an interface is fixedly connected to the end of the air blowing strip. One end of the interface is connected to the inclined groove, and the other end of the interface is connected to an external air source.

[0010] Preferably, the end face of the mounting bracket is trapezoidal, and the cross-section of the storage box is U-shaped.

[0011] Preferably, the bracket has an "L" shaped cross-section, and the knob has a "T" shaped cross-section.

[0012] Preferably, the sandblasting machine body is equipped with a recycling structure, the recycling structure includes a first recycling hopper, the first recycling hopper is fixedly connected to the center of the sandblasting machine body, a separator is fixedly connected to the bottom of the first recycling hopper, and second recycling hoppers are fixedly connected to both sides of the sandblasting machine body.

[0013] Preferably, the two second recovery hoppers are arranged symmetrically, and the bottoms of the two second recovery hoppers are fixedly connected to the separator through recovery pipes.

After being filtered by the filter screen, the abrasive falls into the storage box below, avoiding the problem of the abrasive falling directly to the ground and being inconvenient to clean. The cleaned T-iron falls directly into the storage box. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6As shown, a speaker T-iron surface treatment device includes a sandblasting machine body 1. The sandblasting machine body 1 has a feeding structure 3, which includes guide rods 301. Two guide rods 301 are fixedly connected to the ends of the sandblasting machine body 1. A bracket 302 is slidably connected between the two guide rods 301. A lead screw 304 parallel to the guide rods 301 is provided between them. The bracket 302 is threadedly connected to the lead screw 304. A storage box 305 is engaged on the bracket 302. A mounting bracket 307 is provided above the bracket 302 and is fixedly connected to the sandblasting machine body 1. An air blowing strip 310 is fixedly connected to the top of the mounting bracket 307. An inclined groove 31 is formed inside the air blowing strip 310. 1. An interface 312 is fixedly connected to the end of the air blowing strip 310. One end of the interface 312 is connected to the inclined groove 311, and the other end of the interface 312 is connected to an external air source. A filter screen 308 is fixedly connected to the inner side of the mounting bracket 307. The top of the filter screen 308 abuts against the sandblasting machine body 1, and the bottom of the filter screen 308 abuts against the storage box 305. A mounting plate 313 is fixedly connected to one end of the sandblasting machine body 1 near the guide rod 301. Both guide rods 301 are fixedly connected to the mounting plate 313. A motor 303 is located below the bracket 302. The motor 303 is fixedly connected to the sandblasting machine body 1. One end of the lead screw 304 is fixedly connected to the output shaft of the motor 303. The other end of 4 is rotatably connected to the mounting plate 313. A storage box 309 is provided below the filter screen 308. The storage box 309 is engaged with the inner side of the mounting bracket 307. The bottom surface of the storage box 309 is slidably connected to the mounting plate 313. The outer surface of the storage box 309 abuts against the collection box 305. After being sandblasted, the T-iron enters the area of ​​the mounting bracket 307 from the discharge end. The air blowing strip 310 sprays air outward through the inclined groove 311 and blows away the residual abrasive on the surface of the T-iron. After being filtered by the filter screen 308, the abrasive falls into the storage box 309 below, avoiding the problem of the abrasive falling directly to the ground and being inconvenient to clean. The cleaned T-iron falls directly into the collection box 305. The outer end of the bracket 302 is threadedly connected to... Knob 306, the end of knob 306 abuts against storage box 305, mounting bracket 307 has a trapezoidal end face, storage box 309 has a "U" shaped cross-section, bracket 302 has an "L" shaped cross-section, and knob 306 has a "T" shaped cross-section. Start motor 303, so that its output shaft drives lead screw 304 to rotate. Because bracket 302 is threadedly connected to lead screw 304 and slides along guide rod 301, the height of bracket 302 can be adjusted so that the bottom of storage box 305 on bracket 302 fits against the bottom of filter screen 308. Finally, tighten knob 306 to fix the position of storage box 305, thereby avoiding the problem of T-iron deformation or damage due to the high platform during material unloading.

[0024] As a technical optimization of this utility model, a recovery structure 2 is installed on the sandblasting machine body 1. The recovery structure 2 includes a first recovery hopper 201, which is fixedly connected to the center of the sandblasting machine body 1. A separator 202 is fixedly connected to the bottom of the first recovery hopper 201. Second recovery hoppers 203 are fixedly connected to both sides of the sandblasting machine body 1. The two second recovery hoppers 203 are symmetrically arranged. The bottoms of the two second recovery hoppers 203 are fixedly connected to the separator 202 through a recovery pipe 204. During the sandblasting process, the first recovery hopper 201 collects the mixture in the central area of ​​the sandblasting machine body 1, and the two second recovery hoppers 203 collect the mixture in the edge area. The mixtures collected by both are transported to the separator 202 through the recovery pipe 204 for separation. The separated abrasive can be recycled.

[0025] In use, first clean the residual impurities inside the sandblasting machine body 1 and check the condition of vulnerable parts such as nozzles and sand pipes of its sandblasting components. Then, add suitable abrasive to the equipment. Next, connect the interface 312 to the external air source to ensure that the air blowing strip 310 can spray air normally through the internal inclined groove 311. Then, start the motor 303 so that its output shaft drives the lead screw 304 to rotate. Since the bracket 302 is threadedly connected to the lead screw 304 and slides along the guide rod 301, the height of the bracket 302 can be adjusted so that the bottom of the storage box 305 on the bracket 302 fits against the bottom of the filter screen 308. Finally, tighten the knob 306 to fix the position of the storage box 305, thereby avoiding the problem of deformation or damage to the T-iron due to the high platform during material unloading. Then, the surface of the T-iron can be sandblasted. After starting the equipment, place the T-iron on its conveyor from the feed end of the sandblasting machine body 1. At this time, the T-iron is conveyed... The machine conveys the material to the sandblasting chamber, where multiple sets of spray guns mix the abrasive with compressed air to form a high-speed jet stream that impacts the T-iron surface, achieving rust removal, deburring, and surface roughening. After sandblasting, the T-iron enters the area of ​​the mounting frame 307 from the discharge end. The air blowing strip 310 sprays air outward through the inclined groove 311 and blows away the residual abrasive on the T-iron surface. The abrasive is filtered by the filter screen 308 and falls into the storage box 309 below, avoiding the problem of abrasive falling directly to the ground and being inconvenient to clean. The cleaned T-iron falls directly into the collection box 305. At the same time, for the mixture of abrasive and dust generated by sandblasting, during the sandblasting process, the first recovery hopper 201 collects the mixture in the central area of ​​the sandblasting machine body 1, and the second recovery hoppers 203 on both sides collect the mixture in the edge area. The mixture collected by both is conveyed to the separator 202 through the recovery pipe 204 for separation. The separated abrasive can be recycled.

[0026] After use, turn off the equipment and external air supply, loosen knob 306, remove storage box 305 from bracket 302 and pour out the processed T-iron, then pull out storage box 309 from the inside of mounting bracket 307 along mounting plate 313, clean the residual abrasive in the box, and finally check whether there is any blockage in the first recovery hopper 201, separator 202, second recovery hopper 203 and recovery pipe 204, and ensure that there is no debris left in each structure for the next use.
