Description

Technical Field

[0001] The utility model relates to the technical field of tin bar grinding, in particular to a tin bar grinding dust reduction device. Background Art

[0002] Tin bar is a product of solder. Before the tin bar is made into a finished product, the edges and corners at both ends are sharp when it is taken out of the mold. In addition, due to the fine workmanship of the mold, some slag will be attached to the tin bar. Therefore, some grinding devices are often used to grind the edges and slag to facilitate subsequent processing.

[0003] Tin bar grinding produces debris and dust, which will enter the air with the high-speed rotation of the grinding device, causing damage to the respiratory system and eyes of the workers. The traditional way is to use a vacuum cleaner to suck out the debris and dust generated by grinding. However, grinding will produce some relatively large debris, which will not be directly suspended in the air. To remove such particles, it is necessary to overcome a large gravity, which increases the energy consumption of the vacuum cleaner. At the same time, due to the large particle size, the dust extraction device is more likely to be blocked, so the dust reduction work lacks economy and practicality. In view of this, we propose a tin bar grinding dust reduction device. Utility Model Content

[0004] The purpose of the embodiment of the utility model is to provide a tin bar grinding dust reduction device, which solves the problem that the debris and dust generated during the grinding of the tin bar cannot be processed economically and effectively.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tin bar grinding dust reduction device comprises a support mechanism, on which a protective cover assembly and a dust reduction mechanism are respectively arranged;

[0007] Among them, the supporting mechanism includes a supporting frame and a fixing ring fixedly connected to the top of the supporting frame, a plurality of supporting rods are rotatably connected to the inner circumferential wall of the fixing ring, a fixing shell is arranged at the center of the fixing ring, and one end of the supporting rod away from the fixing ring is rotatably connected to the fixing shell.

[0008] Preferably, a collecting hopper is connected to the bottom of the fixing ring, a discharge pipe is formed at the bottom of the collecting hopper, and an end cover is detachably connected to the surface of the discharge pipe.

[0009] Preferably, the dust reduction mechanism includes a rotating tube, which is rotatably connected to the inner wall of the fixed shell and the inner wall of the collecting bucket respectively. The top end of the rotating tube passes through the fixed shell and is provided with a dust inlet hole, and the bottom end passes through the collecting bucket and is connected to a fan.

[0010] Preferably, the bottom end of the rotating tube is connected to a filter cartridge, a filter screen is connected inside the filter cartridge, and the bottom is connected to an input end of the fan through a pipeline.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Tin bars will generate a lot of debris and dust when grinding. The surface of the grinding piece is rough, and the debris and dust can easily enter the grooves on the surface of the grinding piece, making the surface of the grinding piece flat and affecting the grinding effect. In addition, fine particles entering the air will cause dust pollution, causing damage to the respiratory system and eyes of the workers.

[0027] See also Figure 1-Figure 5 The utility model provides a tin bar grinding dust reduction device, comprising a support mechanism 1, on which a protective cover assembly 2 and a dust reduction mechanism 3 are respectively arranged. The protective cover assembly 2 is used to cover the grinding area to prevent the debris and dust generated by grinding from diffusing out of the grinding area, thereby facilitating dust reduction. The dust reduction mechanism 3 is used to remove and reduce dust in the grinding area to ensure the cleanliness of the working environment.

[0028] Specifically, the support mechanism 1 includes a support frame 11 and a fixing ring 12 fixedly connected to the top of the support frame 11, and a plurality of support rods 13 are rotatably connected to the inner peripheral wall of the fixing ring 12. The plurality of support rods 13 are distributed in a circular array with the axis of the fixing ring 12 as the center, and the outer surface of the support rods 13 is arc-shaped, so that debris is not easy to remain on it. The support rods 13 can be rotated, and the debris attached to them falls naturally during the rotation process.

[0029] Furthermore, a fixed shell 14 is provided at the center of the fixed ring 12, and the ends of the plurality of support rods 13 away from the fixed ring 12 are all rotatably connected to the fixed shell 14, and the fixed shell 14 is used to support the other ends of the support rods 13. The fixed ring 12, the fixed shell 14 and the support rods 13 together constitute the table of the support mechanism 1, and a grinding device (not shown in the figure) is provided on the table. Compared with the traditional flat table, the table has a plurality of gaps distributed in a circular array, and the surface of the support rod 13 is arc-shaped, so that debris can fall by gravity, and by rotating the support rod 13, the debris attached to the table can be removed to ensure the cleanliness of the table.

[0030] A collecting bucket 15 is connected to the bottom of the fixing ring 12 for collecting fallen debris. A discharge pipe is formed at the bottom of the collecting bucket 15, and an end cover 16 is connected to the surface of the discharge pipe by threads or snaps, so that the end cover 16 can be removed easily to clean the debris in the collecting bucket 15.

[0031] As one embodiment, the protective cover assembly 2 includes a fixed cover 21 fixedly connected to the top of the fixed ring 12, and the surface of the fixed cover 21 is rotatably connected to the movable cover 22. Specifically, an annular groove is provided on the outer surface of the fixed cover 21, and the top of the movable cover 22 is embedded in the annular groove and rotatably connected to the annular groove. Both the fixed cover 21 and the movable cover 22 are provided with openings. When in use, the movable cover 22 can be rotated to adjust the angle of the opening on the movable cover 22. When the two openings overlap, a loading and unloading port is formed, which is convenient for users to load and unload. When the two openings do not overlap, the grinding area can be closed, so that the debris and dust generated by grinding are limited to a certain range, which is convenient for dust reduction treatment. The fixed cover 21 and the movable cover 22 are both made of transparent materials, such as acrylic, glass, etc., so that the staff can observe the grinding situation.

[0032] As an embodiment, the dust reduction mechanism 3 includes a rotating tube 31, which is rotatably connected to the inner wall of the fixed shell 14 and the inner wall of the collecting bucket 15, respectively. The top of the rotating tube 31 passes through the fixed shell 14 and is provided with a plurality of dust inlet holes, and the bottom of the rotating tube 31 passes through the collecting bucket 15 and is connected to a fan 33. The fan 33 rotates to generate negative pressure, and the dust suspended in the air in the grinding area is sucked to achieve the purpose of dust reduction.

[0033] Furthermore, the bottom end of the rotating tube 31 is connected to a filter cartridge 32, a filter screen 34 is connected inside the filter cartridge 32, and the bottom is connected to the input end of the fan 33 through a pipeline. Dust can be collected and filtered through the filter cartridge 32 and the filter screen 34. The top end of the filter cartridge 32 is rotatably connected to the rotating tube 31 to avoid motion interference, and the bottom end of the filter cartridge 32 is threaded or clamped to the pipeline to facilitate disassembly of the filter cartridge 32.

[0034] As an embodiment, the tin bar grinding and dust reduction device further includes a transmission mechanism 4 for driving the rotating tube 31 and the support rod 13 to rotate.

[0035] See also Figure 3 The transmission mechanism 4 includes a lifting frame 46 fixedly connected to the support frame 11, a motor 45 is fixedly installed on the top of the lifting frame 46, a driving gear 44 is fixedly connected to the output end of the motor 45, a reduction gear 43 is meshed on the surface of the driving gear 44, and the axis of the reduction gear 43 is fixedly connected to the surface of the rotating tube 31. The diameter of the reduction gear 43 is larger than the diameter of the driving gear 44, and the driving gear 44 drives the reduction gear 43 to rotate, which can achieve the purpose of deceleration, thereby preventing the rotating tube 31 from rotating too fast.

[0036] See also Figure 4 The transmission mechanism 4 also includes a first bevel gear 41 fixedly connected to the surface of the rotating tube 31, and a second bevel gear 42 is fixedly connected to one end of each of the plurality of support rods 13, and each of the plurality of second bevel gears 42 is meshed with the first bevel gear 41. When the rotating tube 31 rotates, the first bevel gear 41 can synchronously drive the plurality of second bevel gears 42 to rotate, thereby simultaneously driving the plurality of support rods 13 to rotate, so that the portion of the support rod 13 with debris attached faces downward, thereby promoting the debris to fall off.

[0037] When the tin bar grinding dust reduction device of the utility model is used, the movable cover 22 is rotated so that the opening on the movable cover 22 overlaps with the opening on the fixed cover 21, and then the material is loaded. After loading, the movable cover 22 is continued to be rotated so that the two openings do not overlap, and then the grinding area is closed. During grinding, the grinding situation can be observed through the transparent fixed cover 21 and the movable cover 22. The debris generated by grinding will fall into the collection bucket 15 under the action of gravity, a small amount of debris will fall on the support rod 13, and fine dust will be suspended in the air in the grinding area.

[0038] Starting the motor 45 can drive the driving gear 44 to rotate, and the driving gear 44 drives the rotating tube 31 to rotate through the reduction gear 43. The rotating tube 31 drives multiple second bevel gears 42 to rotate through the first bevel gear 41, and then drives multiple support rods 13 to rotate at the same time, changing the angle of the support rods 13 and promoting the falling of debris attached to the support rods 13. Starting the fan 33 will generate negative pressure, and then the dust suspended in the grinding area will be sucked into the filter cartridge 32 through the dust inlet hole at the top of the rotating tube 31. The filter cartridge 32 and the filter net 34 can collect and filter the dust, and the filtered gas will be discharged into the air again through the fan 33.
