Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a suction-type dust collection device. Background Art

[0002] The abrasive belt polisher is different from the single-head manual polisher. The multi-head automatic polisher adopts a processing method in which the two working ends are fixed, the polishing mechanism moves along the center line of the workpiece, and the abrasive belt moves in contact with the surface of the workpiece.

[0003] When the round tube polishing mechanism is working, the dust of the workpiece and the sand belt debris produced by grinding are thrown outward along the radial direction of the polishing mechanism. Adding a protective cover to absorb dust around can simply solve the problem of single-head manual dust removal, but it cannot be handled for multi-head sand belt polishers. Because the multi-station polishing mechanism is working, the large workload of dust spreads all around. If it is not properly solved, it will not only cause serious dust pollution, but also directly reduce the service life of the equipment, and even cause serious safety accidents. For example, metal conductive dust accumulates on the electrical circuit and causes short circuit and leakage, which may damage the equipment at the least and threaten the safety of the operator at the worst.

[0004] The Chinese patent with publication number CN211517164U discloses an internal suction dust collection device for a multi-head abrasive belt polisher, which includes a fixed plate, on which a plurality of reducers are fixedly installed along the length direction, the output shaft of the reducer is a hollow structure and the top of the output shaft is connected to a rotating seat, the surface of the rotating seat is fixedly connected to a dust cover, and both sides of the dust cover are provided with through holes that match the abrasive belt grinding mechanism, and a dust collecting cover is fixedly installed at the bottom of the fixed plate, and the output shaft of the reducer connects its corresponding dust cover with the dust collecting cover, and the dust collecting cover is connected to a dust outlet, and the dust generated by the processing of the pipe fittings of the utility model is collected in a sealed state, which reduces the scattering of dust on the machine tool, keeps the overall cleanliness of the machine tool, reduces the pollution to the environment, makes the working environment cleaner, especially the transmission system and the electrical system, and increases the service life of the machine. In the above scheme, the reducer is arranged in the dust collecting cover, and the dust moves in the dust collecting cover. As a result, the dust can enter the interior of the reducer, thereby shortening the service life of the reducer. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1-3 As shown, a suction-type dust collection device of the utility model has a support seat 01 and a transmission assembly fixedly mounted on the support seat 01, one end of the transmission assembly is connected to a connecting seat 02, the connecting seat 02 is located above the support seat 01, the other end of the transmission assembly is connected to a driving assembly 07, the driving assembly 07 is located below the support seat 01, a dust collection hood 03 is arranged between the connecting seat 02 and the support seat 01, and the dust collection hood 03 is connected to the connecting seat 02. When the grinding mechanism on the connecting seat 02 is working, the generated dust enters the dust collection hood 03 through the connecting seat 02. It is discharged to the outside of the dust collection hood 03 through the exhaust fan. Since the driving assembly 07 is located outside the dust collection hood 03, when the dust enters the dust collection hood 03 from the connecting seat 02, the dust cannot enter the inside of the driving assembly 07, thereby improving the service life of the driving assembly 07.

[0024] like Figure 2As shown, the transmission assembly includes a lower fixed seat 04 fixedly mounted on the support seat 01, a connecting shaft 05 is rotatably mounted on the lower fixed seat 04 through a bearing, an upper fixed seat 06 is fixedly connected to the top of the connecting shaft 05, and the upper fixed seat 06 and the lower fixed seat 04 are spaced apart and rotatably connected to the top surface of the dust collecting hood 03. The transmission support 01 at the bottom end of the connecting shaft 05 is fixedly connected to the driving assembly 07. A connecting hole 14 is provided on the upper fixed seat 06, which passes through the connecting seat 02 and the dust collecting hood 03. When in use, dust generated by the grinding mechanism when working falls into the dust collecting hood 03 through the connecting hole 14.

[0025] like Figure 2-3 As shown, a dust outlet 08 and a mounting port 09 located on one side of the dust outlet 08 are provided on the bottom surface of the dust hood 03. The dust outlet 08 extends toward the support seat 01, and the mounting port 09 is covered on the lower fixing seat 04, so that the lower fixing seat 04 is located in the dust hood 03. A mounting ring 10 is provided at the mounting port 09, and a fastener passes through the mounting ring 10 and is fixedly connected to the support seat 01. Another way to connect the dust hood 03 and the support seat 01 is to directly fix the mounting port 09 to the support seat 01 by welding.

[0026] By arranging an exhaust fan on the dust outlet 08 , the dust generated when the grinding mechanism is working enters the dust suction hood 03 through the connecting hole 14 on the upper fixing seat 06 under the action of the exhaust fan and is then discharged through the dust outlet 08 .

[0027] like Figure 2 As shown, a transition hole 11 is provided on the top surface of the dust hood 03, and the upper fixing seat 06 is located in the transition hole 11. The transition hole 11 is covered with two symmetrically arranged sealing plates 12. The sealing plates 12 are fixedly installed with the top surface of the dust hood 03 by fasteners, and each sealing plate 12 is provided with a semicircular sealing hole. The sealing holes on the two sealing plates 12 are combined into a complete through hole 13, and the through hole 13 is adapted to the upper fixing seat 06. The diameter of the transition hole 11 is larger than the diameter of the upper fixing hole, which facilitates the installation of the dust hood 03 during the installation process. The design of the two sealing plates 12 prevents dust from overflowing from the transition hole 11.

[0028] A sealing groove 15 is provided on the outer circumferential rear surface of the upper fixing seat 06, and the inner diameter of the sealing groove 15 is adapted to the through hole 13, so that both sealing plates 12 are inserted into the sealing groove 15. The width of the sealing groove 15 is adapted to the thickness of the sealing plate 12. The matching mode of the sealing groove 15 and the sealing plate 12 further prevents the dust in the dust collecting shield 03 from overflowing through the gap between the transition port and the upper fixing seat 06.

[0029] Several transmission components are arranged on the support base 01, and each transmission component passes through the dust cover 03 and is fixedly connected to the corresponding connection base 02. A connection base 02 is fixedly installed on each connection base 02. A driving component 07 rotates on the support base 01 through the transmission component at the bottom of the support base 01.

[0030] like Figure 3 As shown, the driving assembly 07 includes the same number of reducers as the transmission assembly, and two adjacent reducers are connected via a transmission shaft.

[0031] like Figure 1-3 As shown, a cover 16 is fixedly installed on the connecting seat 02. The setting of the cover 16 prevents all dust generated when the grinding mechanism is working from entering the connecting seat 02, and also ensures that all dust can enter the dust collection cover 03.

[0032] The present application also provides a polishing machine, comprising the above-mentioned suction-type dust collection device.

[0033] It should be noted that, for the sake of clarity of description, the fasteners described in this application are any one of screws, bolts, and screws.

[0034] If the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
