Description

Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding machine with a dust removal function. Background Art

[0002] A grinding machine is a device used to grind and polish workpieces during the production process. It can modify the appearance of the product to avoid problems such as burrs that affect the product's effect.

[0003] In the prior art, since the grinding machine grinds the product little by little, a large amount of dust will be generated. If the dust is not removed, the production workshop will be filled with dust, which will affect the health of the workers and cause damage to the equipment. Therefore, it is necessary to add a dust removal function to the grinding machine. Utility Model Content

[0004] The utility model aims to solve the above technical problems and provides a grinding machine with a dust removal function.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a grinding machine with a dust removal function, comprising a dust removal box, a dust suction sleeve is fixedly connected to one side of the outside of the dust removal box, the dust suction sleeve is communicated with the lower end of the dust removal box, a grinding disc is rotatably connected to the inside of the dust removal box, a plurality of No. 2 baffles are fixedly connected to the inside of the dust removal box at equal intervals, a negative pressure fan is provided on the top of the dust removal box, a discharge port is opened at the bottom of the dust removal box, and a No. 3 baffle is provided on the dust removal box at the position of the discharge port.

[0006] As a preferred technical solution of the utility model, the air inlet end of the negative pressure fan is connected to the top of the dust removal box, and the air inlet end of the negative pressure fan is provided with a dustproof net located inside the dust removal box.

[0007] As a preferred technical solution of the utility model, the bottom of the dust removal box is provided with an inclined surface inclined toward the discharge port.

[0008] As a preferred technical solution of the utility model, a baffle No. 1 is fixedly connected to the inner wall of the upper section of the dust collection sleeve.

[0009] As a preferred technical solution of the utility model, a discharge hopper is fixedly connected to the outer wall of the dust removal box at the discharge port, a No. 2 magnet is fixedly connected to the bottom of the No. 3 baffle near the discharge port, and a No. 1 magnet is fixedly connected to the position of the dust removal box relative to the No. 2 magnet, and the magnetism of the No. 1 magnet and the No. 2 magnet on the side close to each other is the same.

[0010] The utility model has the following advantages: the grinding machine is provided with a dust removal box. When the grinding disc rotates rapidly to grind the product, the dust removal box draws out air through the negative pressure fan to create negative pressure, and absorbs the dust produced by grinding through the dust suction sleeve to avoid dust diffusion. After the dust enters the dust removal box, it hits the No. 2 baffle plate of the elder brother under the action of inertia, avoiding direct excessive impact on the filter screen of the negative pressure fan and causing damage. When the filter screen of the negative pressure fan is blocked, the suction force on the dust is reduced, and the dust falls on the inclined surface at the bottom and is discharged from the discharge port, avoiding excessive dust in the dust removal box.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] Please refer to Figure 1-3 The utility model is a grinding machine with a dust removal function, comprising a dust removal box 1, a dust suction sleeve 2 is fixedly connected to one side of the outside of the dust removal box 1, the dust suction sleeve 2 is communicated with the lower end of the dust removal box 1, a grinding disc 3 is rotatably connected to the inside of the dust removal box 2, a plurality of No. 2 baffles 6 are equidistantly fixedly connected to the inside of the dust removal box 1, a negative pressure fan 5 is provided on the top of the dust removal box 1, a discharge port 9 is opened at the bottom of the dust removal box 1, and a No. 3 baffle 10 is provided at the position of the discharge port 9 of the dust removal box 1.

[0019] The air inlet end of the negative pressure fan 5 is connected to the top of the dust removal box 1, and a dust-proof net is provided at the air inlet end of the negative pressure fan 5 and inside the dust removal box 1. A slope 7 inclined toward the discharge port 9 is provided at the bottom of the dust removal box 1. The upper inner wall of the dust suction cover 2 is fixedly connected to the No. 1 baffle 4. After being blocked by the No. 1 baffle 4, it cannot be sprayed out and is captured by the dust suction cover 2 and sucked into the dust removal box 1 again. The outer wall of the dust removal box 1 and the position of the discharge port 9 are fixedly connected with a discharge hopper 8. The bottom of the No. 3 baffle 10 close to the discharge port 9 is fixedly connected with the No. 2 magnet 12. The position of the dust removal box 1 relative to the No. 2 magnet 12 is fixedly connected with the No. 1 magnet 11. The magnetism of the No. 1 magnet 11 and the No. 2 magnet 12 on the side close to each other is the same. The internal air pressure of the dust removal box 1 is restored, and the reverse thrust of the No. 1 magnet 11 and the No. 2 magnet 12 pushes the No. 3 baffle 10 away from the discharge port 9, thereby opening the discharge port 9.

[0020] Specifically, when the utility model is used, the negative pressure fan 5 is turned on, and the air inlet pipe of the negative pressure fan 5 draws out the air in the dust removal box 1, so that negative pressure is formed in the dust removal box 1. At this time, the outside air quickly flows into the dust removal box 1 from the dust collection sleeve 2 and the discharge port 9. When the thrust force received by the third baffle 10 is greater than the repulsive force of the two magnets, the third baffle 10 closes the discharge port 9.

[0021] When the workpiece is ground with the grinding disc 3, a large amount of dust is generated. The dust enters the dust collection sleeve 2 under the action of centrifugal force, and enters the dust collection box 1 through suction. A small part of the dust flows out from the top of the dust collection sleeve 2 under the action of centrifugal force, but cannot be ejected after being blocked by the first baffle 4, and is captured by the dust collection sleeve 2 and sucked into the dust collection box 1 again.

[0022] The dust entering the dust removal box 1 will rush to the top of the dust removal box 1 under the action of suction and inertia. After being blocked by multiple No. 2 baffles 6, the speed of the dust reaching the filter screen of the negative pressure fan 5 is reduced, thereby avoiding damage to the filter screen of the negative pressure fan 5.

[0023] As the equipment runs for a longer time, the filter screen of the negative pressure fan 5 is gradually clogged. At this time, the suction force of the dust collection sleeve 2 is reduced. After stopping the grinding, the negative pressure fan 5 is turned off. The dust slides down the No. 2 baffle 6 and the inclined plane 7 to the position of the discharge port 9 under the action of its own weight. At this time, due to the recovery of the air pressure inside the dust removal box 1, the reverse thrust of the No. 1 magnet 11 and the No. 2 magnet 12 pushes the No. 3 baffle 10 away from the discharge port 9. After the discharge port 9 is opened, the dust is discharged through the discharge hopper 8 to avoid excessive dust inside the dust removal box 1.

[0024] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0025] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
