Description

Technical Field

[0001] The utility model belongs to the technical field of industrial dust removal equipment, and in particular relates to a baffle-type machine tool dust collecting cover. Background Art

[0002] Machine tools refer to equipment for manufacturing machines. Machine tools are generally divided into metal cutting machine tools, forging machine tools, woodworking machine tools, etc. There are many methods for processing accessories. In addition to cutting, there are also casting, forging, welding, stamping and extrusion. Among them, parts with higher requirements for precision and finer surface roughness generally need to be finally processed on machine tools. Therefore, machine tools play a major role in the construction of national economic modernization.

[0003] During the machining process of machine tools, metal cutting, polishing and other operations will generate a lot of dust. This dust not only affects the working environment and causes environmental pollution, but also may threaten the health of operators. Therefore, it is very important to effectively collect and control the dust generated by machine tools. At present, although various dust collection hoods have been applied to machine tools, there is still the problem that the use of dust collection hoods is not flexible enough, resulting in poor dust collection effect.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a baffle-type machine tool dust hood, comprising a negative pressure bellows, symmetrical guide rails are fixedly connected on both sides of the lower end of the negative pressure bellows, the guide rails are provided with guide grooves, a first slider and a second slider are provided in the guide grooves, an air inlet pipe is provided in the middle of the lower end of the negative pressure bellows, the air inlet pipe is connected to a transfer box, the rear end of the transfer box is connected to a dust collecting device, a dust removal box is fixedly provided on the upper end of the guide rail, an air outlet pipe is provided at the rear end of the negative pressure bellows, and the end of the air outlet pipe is connected to the dust removal box.

[0006] Furthermore, the negative pressure air box includes a front baffle, a partition, a negative fan, bolts, a rear baffle, and an air intake pipe. The partition is arranged on the inner side of the negative pressure air box, and the negative fan is fixedly arranged on the partition. The front baffle and the rear baffle are connected to the negative pressure air box by bolts.

[0007] Furthermore, the dust collecting device includes a reducer, a bellows, a dust collecting hood, and a dust collecting hose. The left end of the reducer is fixedly connected to the right end of the dust collecting hose, and the right end of the reducer is fixedly connected to the left end of the dust collecting hood through the bellows.

[0008] Furthermore, the dust removal box includes a cover, a filter, a dust collection drawer, a handle, and an air vent. The filter is arranged inside the dust removal box, the dust collection drawer is arranged at the lower end of the dust collection drawer, the dust collection drawer is provided with a handle, and the air vent is arranged at the right end of the dust removal box.

[0009] Furthermore, one end of the first sliding block is arranged in the guide groove, and the other end is sleeved with a dust collecting hose; one end of the second sliding block is arranged in the guide groove, and the other end is fixedly connected to the dust collecting hose.

[0010] The utility model has the following beneficial effects:

[0011] The baffle-type machine tool dust collecting cover is provided with a negative pressure bellows, a dust collecting device, a dust removal box, and a guide rail. When in use, the dust collecting device can move in the guide groove of the guide rail, and the dust collecting device can be moved to a corresponding position according to the position where the machine tool dust is generated, so that the dust is absorbed more accurately and the operation is flexible.

[0012] When in use, the negative fan of the negative pressure bellows quickly draws the air collected by the dust collecting device in the transfer box into the dust removal box, thereby forming negative pressure in the negative pressure bellows. Due to the change in the diameter of the reducer of the dust collecting device, the air outside the dust hood quickly flows through the dust hood and the bellows to the inside of the reducer, increasing the air flow rate and improving the dust removal efficiency.

An air outlet pipe 2 is arranged at the rear end of the negative pressure bellows 1, and the end of the air outlet pipe 2 is connected to the dust removal box 3.

[0022] Among them, the partition 102 is arranged on the inner side of the negative pressure wind box 1, and a negative fan 103 is fixedly arranged on the partition 102. The front baffle 101 and the rear baffle 105 are connected to the negative pressure wind box 1 through bolts 104. The negative fan 103 quickly draws the air collected by the dust collecting device 5 to the transfer box 6 to the dust removal box 3, so that negative pressure is formed in the negative pressure wind box 1; the left end of the reducer 501 is fixedly connected to the right end of the dust collecting hose 504, and the right end of the reducer 501 is fixedly connected to the left end of the dust collecting cover 503 through the bellows 502. The diameter of the reducer 501 changes, so that the air outside the dust collecting cover 503 quickly flows through the dust collecting cover 503 and the bellows 502 to the inside of the reducer, thereby increasing the air flow rate; the filter 30 2 is arranged inside the dust removal box 3, four groups of filters 302 are arranged to intercept dust, a dust collecting drawer 303 is arranged at the lower end inside the dust removal box 3, and a handle 304 is arranged on the dust collecting drawer 303 to facilitate regular cleaning of collected dust, and an air vent 305 is arranged at the right end of the dust removal box 3 to discharge dust-free air; one end of the first slider 8 is arranged in the guide groove 7, and the other end is sleeved with a dust collecting hose 504, one end of the second slider 9 is arranged in the guide groove 7, and the other end is fixedly connected to the dust collecting hose 504, so that the dust collecting device 5 can move in the guide groove 7 of the guide rail 4, and the dust collecting device 5 is moved to the corresponding position according to the position where the machine tool dust is generated, so that the dust is absorbed more accurately and the operation is flexible.

[0023] Working principle: Before use, first pull the dust hood 503 along the guide groove 7 of the guide rail 4, stop when it reaches the position where it needs to be used, and then start the negative blower 103 of the negative pressure bellows 1, the dust hood 503 sucks the air with dust into the bellows 502, and enters the reducer 501 through the bellows 502. The diameter of the reducer 501 changes from bottom to top, so that the air outside the dust hood 503 quickly flows through the dust hood 503 and the bellows 502 to the inside of the reducer, increasing the air flow rate, and the air quickly enters the dust collecting hose 504, and passes through the dust collecting hose Tube 504 reaches the transfer box 6, and the transfer box 6 is connected to the negative pressure bellows 1 through the air inlet pipe 106. The negative pressure bellows 1 is in a negative pressure state. The air in the transfer box 6 quickly enters the negative pressure bellows 1, and enters the dust removal box 3 through the air outlet pipe 2. After the dust passes through the filter 302, it is trapped and concentrated in the dust collecting drawer 303 at the bottom of the dust removal box 3. Dust-free air is discharged through the air vent 305. After the device is used for a long time, the dust collecting drawer 303 is pulled out through the handle 304 to clean the dust in the dust collecting drawer 303. The cleaning is convenient, the overall operation of the device is flexible, and the dust removal efficiency is high.
