Description

Grinder with dust extraction device

technical field

The utility model relates to a machine for metal surface treatment, in particular to a polishing machine with a dust removal device.

Background technique

Sander, also known as belt machine or polishing machine, is a processing machine for grinding and polishing the surface of metal or other materials. The main structure of the currently used belt sander includes a machine base. The driving wheel driven by the motor and the driven wheel are installed on the frame. When working, the high-speed rotation of the driving wheel drives the abrasive belt to perform high-speed cutting movement, and the dust that occurs during the processing is removed by a dust removal device. Most of the devices are composed of several grinding machines sharing one main pipe, and the dust is discharged centrally by one main machine. No matter how many machines are turned on, the main machine must run, which increases the operating cost of the equipment. The negative pressure formed during work is used to suck away the dust, but the dust generated during processing has a high linear velocity, so it is difficult to be sucked away by the negative pressure formed by the draft, and the dust removal effect is difficult to guarantee.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a polishing machine with cost saving, convenient adjustment and good dust removal effect.

The technical scheme that the utility model solves its technical problem adopts is:

A polishing machine with a dust removal device, which includes a base, a main shaft arranged on the base and driven by a motor, a driving wheel is installed on the main shaft, and a driven wheel is also arranged on the frame. The driving wheel passes through the abrasive belt and the driven wheel The driving wheel is connected, and a dust collection device is installed on the frame. The dust collection device includes a dust collection cover that can accommodate the driving wheel and the driven wheel. A processing port and one or more water nozzles are provided at the dust collection cover near the abrasive belt. , the lower part of the dust collection hood is provided with an air guide groove, the opening on one side of the air guide groove leads to the processing port, the opening on the other side leads to the water baffle, the other end of the water baffle leads to the air outlet, the bottom of the dust collection hood With drainage device.

The beneficial effects of the utility model are: this design is provided with a water spray nozzle on the dust collection hood, and through the combined action of water curtain formed in the dust collection hood and negative pressure ventilation, the dust can be effectively collected to achieve purification Dust removal effect, the water mixed with dust can be recycled after being filtered, and the airflow can remove the water droplets trapped in the air when passing through the water baffle, so that the air discharged from the outside will not overflow with water droplets. In addition, the dust removal design of this design The device is independently installed on the grinder and adopts a separate control method, which can save operating costs and will not be affected when it needs to be moved or adjusted.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a structural representation of the utility model.

Detailed ways

With reference to Fig. 1, a kind of grinder with dust removal device, its main structure has organic base 1, the main shaft 11 that is movably installed on the base and driven by the motor, on the main shaft 11 drive wheel 12 is housed, under the drive of motor, The main shaft 11 drives the driving wheel 12 to rotate at a high speed, and a driven wheel 13 is also arranged on the frame. The driving wheel 12 is connected with the driven wheel 13 through an abrasive belt 14, and the driving wheel 12 is driven to cover the driving wheel 12 and the driven wheel during work. The abrasive belt 14 on the 13 rotates at a high speed to grind and cut the workpiece. A dust collection device 2 is arranged on the frame. The dust collection device has a dust collection cover 21 installed on the machine base. 12. The driven wheel 13 and the abrasive belt 14 are accommodated inside, and the outer panel of the dust collection cover is provided with an openable movable door 28 at a position corresponding to the abrasive belt, which can be used to replace the abrasive belt or clean the inside of the dust collection cover. There is a processing port 22 on the cover close to the driving wheel, and the workpiece is processed from the processing port and the abrasive belt. The left and right sides of the dust collection cover are respectively provided with water nozzles 23, the left water nozzle is arranged at the bottom of the processing port, and the right spray nozzle The water nozzle can be installed on the upper part of the other side plate of the dust collection hood corresponding to the processing port. When spraying water, the water nozzles opposite to the left and right can form a cross water curtain. The water guide plate 27 tending to the air guide groove, the lower part of the dust collection cover is provided with the air guide groove 24, the air guide groove of this design is an arc-shaped channel made of multiple curved plates, and the bottom of the curved plate at the bottom is between the lowest point and the bottom. There is a narrow gap between them. The front opening of the air guide groove leads to the processing port, and the opening at the rear end leads to the water baffle 25. The water baffle is composed of multi-layer wave-shaped plates with a certain gap. The space formed by the gap between the plates It is an upward curved air flow channel, the other end of the water retaining plate can lead to the air outlet 26, and the bottom part of the dust collection cover is provided with a drain port 31 connected with a water tank 32 with a filter screen.

During work, the parts are ground and cut by the abrasive belt at high speed in the processing port. During this process, a large amount of dust and particles are produced. When they meet the cross water curtain, some of them are mixed with water and taken away, and pass through the air guide groove in the dust collection hood. When fully mixed to achieve the dust collection effect, the water mixed with a large amount of dust is discharged into the water tank 32 below along the drain outlet at the bottom of the dust collection hood, and is recycled and reused after being filtered by the filter screen arranged in the water tank, while the air flow path passes through the air guide After the groove 24, it enters in the water retaining plate 25, and the water droplets mixed in the air can be removed when passing through the water retaining plate 25, so that the air discharged from the outside world overflows without water droplets.

The dust removal device of this design is independently installed on the polishing machine, and works simultaneously with the polishing machine in a separate control mode, which can save operating costs, and will not be affected when the equipment needs to be moved or adjusted, avoiding the trouble of modification and disassembly , the dust removal device of the utility model can be widely used in the supporting equipment of the new type of grinding machine, and it is relatively easy to modify the old equipment in use. This design is not only suitable for single-head grinding machines with only one set of abrasive belt grinding mechanisms , and is also suitable for double-headed grinders with belt grinding mechanisms arranged symmetrically on both sides.
