DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution in the present application, the technical solution of the present utility model will be clearly and completely described below in conjunction with the drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present application. Example

[0024] like Figure 1-4As shown, a gold grinder of this embodiment includes a grinder housing 1, a drive motor 4, a polishing member 5, an air pump 14, a dust collecting box 3 and a controller 8. The grinder housing 1 is divided into an operating room 101 and an equipment room 107 by a partition 106. A dust collecting groove 103 and a negative pressure chamber 16 are provided at the bottom of the operating room 101. A partition net 104 is installed on the top of the dust collecting groove 103 and a notch is provided on one side thereof. An operating port 1011 is provided on one side of the operating room 101. The drive motor 4 is provided with a drive shaft 41 and is installed in the equipment room 107. The drive shaft 41 passes through the partition 106 and extends to the operating room 101. The polishing member 5 is placed in the operating room 101 and is connected to the drive shaft 41 in a transmission manner. The air pump 14 is installed in the equipment room 107 and connected to the negative pressure chamber 16; the dust box 3 is inserted into the dust collecting groove 103 through the notch, and at least one through hole 36 is opened on the side close to the negative pressure chamber 16, and at least one negative pressure hole 161 corresponding to the at least one through hole 36 is opened on the negative pressure chamber 16. The controller 8 is installed on the mill housing 1 and is electrically connected to the drive motor 4 and the air pump 14 respectively.

[0025] like Figure 1 and 2 As shown, the operating room 101 is provided with a side panel 102, and the side panel 102 is provided with an operating slot 1021. The operating slot 1021 can provide an operating space for the operator when performing gold polishing in the operating room 101.

[0026] The number of through holes can be 1, 2 or 3, etc., and correspondingly, the number of negative pressure holes can also be 1, 2 or 3, etc.

[0027] The vacuum pump 14 extracts the gas in the negative pressure chamber 16, so that the negative pressure chamber 16 forms a negative pressure, and then the negative pressure chamber 16 extracts the gas in the dust box 3 through the negative pressure hole 161 and the through hole 36 thereon, so that the dust box 3 forms a negative pressure, and the dust box 3 extracts the gas on the top. Therefore, the dust particles generated by polishing gold are acted downward by the negative pressure and are sucked into the dust box below the partition.

[0028] The controller 8 is used to control the operation of the drive motor 4 and the vacuum pump 14. It is understandable that the controller has a touch screen.

[0029] The controller 8 may be preset with gears of the drive motor 4, such as gear I, gear II, gear III, and gear IV, and the speed of the drive motor increases from gear I to gear IV. A suitable gear may be selected according to the grinding needs.

[0030] like Figure 1-3 As shown, a structure of a polishing member 5. The polishing member 5 includes a polishing head 51, a connecting end 52 and screws 53. The polishing head 51 is connected to the connecting end 52, and the connecting end 52 is provided with at least two screws 53; wherein the connecting end 52 is sleeved on the driving shaft 41, and the screws 53 are tightened, so that the connecting end 52 is fixedly connected to the driving shaft 41.

[0031] The polishing piece 5 is detachably mounted on the driving shaft through the connecting end and the screw, so that polishing pieces of different specifications can be easily replaced.

[0032] like Figure 1-3 As shown, one structural form of the polishing head is a conical structure. Of course, the structural shape of the polishing head can be not limited to this, but can also be a disc, a cylinder, and other structural shapes.

[0033] How polishing parts work:

[0034] The driving motor 4 is controlled by the controller 8 to work, and the driving motor 4 drives the driving shaft 41 to rotate, and the driving shaft 41 drives the polishing member 5 installed thereon to rotate.

[0035] In some embodiments of the present disclosure, a structure of a dust collecting box is provided. Figure 1 , 2 As shown in Figures 4 and 5, the dust collecting box 3 includes a box body 31, a baffle 32, a sealing gasket 34 and a handle 33. A dust collecting bag 35 is suspended in the box body 31, and at least one through hole 36 is opened on the side of the box body 31 close to the negative pressure chamber 16. The baffle 32 is installed at one end of the box body 31 and is used to buckle the notch. The sealing gasket is installed on one side of the baffle 32 close to the box body 31. The handle 33 is installed on the other side of the baffle 32.

[0036] The box body 31 is inserted into the dust collecting groove 103 through the notch of the dust collecting groove 103, and when the baffle 32 is inserted and covers the notch, the baffle 32 is connected to the mill housing 1 through the sealing gasket 34. When the vacuum pump 14 extracts the gas in the negative pressure chamber 16, the negative pressure chamber 16 extracts the gas in the box body 31 through the negative pressure hole 161 and the through hole 36, so that negative pressure is formed in the box body 31. At this time, under the action of atmospheric pressure, the baffle 32 is squeezed by the atmospheric pressure, and the baffle 32 squeezes the sealing gasket on the mill housing, thereby improving the airtightness between the baffle and the mill housing.

[0037] It should be noted that when the dust bag on the dust collecting box needs to be cleaned, the polishing part stops processing and the air pump stops pumping. The baffle 32 is pulled by the handle 33, and the baffle 32 pulls the box body 31 out of the dust collecting groove, so that the dust bag can be cleaned.

[0038] In some embodiments of the present disclosure, an inclined plate 105 is additionally installed. The inclined plate 105 is installed on the edge of the top surface of the dust collecting trough 103.

[0039] The inclined plate 105 facilitates the particles falling thereon to be guided to the top of the partition net, and then fall from the partition net into the dust collecting box.

[0040] It should be noted that the inclined plate and the side of the operating chamber can be connected by an arc transition, which can reduce the accumulation of polishing waste such as dust, particles, gold powder residue, etc. at the connection between the inclined plate and the side of the operating chamber.

[0041] In some embodiments of the present disclosure, a connection structure between an air pump and a negative pressure chamber is provided, and an air extraction pipe 15 and an air supply pipe 13 are additionally installed. Figure 1 and 2 As shown, one end of the exhaust pipe 15 is connected to the exhaust end of the exhaust pump 14, and the other end is connected to the negative pressure chamber 16; one end of the air supply pipe 13 is connected to the air outlet end of the exhaust pump 14, and the other end extends out of the equipment room 107.

[0042] Working mode of vacuum pump:

[0043] The vacuum pump 14 is controlled by the controller 8 to extract the gas in the negative pressure chamber 16 through the vacuum pipe 15, so that the negative pressure chamber 16 forms a negative pressure; and the extracted gas is discharged into the air supply pipe 13, and the air supply pipe 13 then discharges the gas out of the mill casing.

[0044] In some embodiments of the present disclosure, in order to reduce the wind pressure discharged from the air supply pipe, a pressure reducing member 12 is additionally installed. The pressure reducing member 12 is placed in the equipment room 107, and its air outlet end is installed on the mill housing 1, and a screen 11 is installed on the air outlet end; the air supply pipe 13 is connected to the air inlet end of the pressure reducing member 12.

[0045] like Figure 1 , 2 As shown, one structure of the pressure reducing member 12 is a square horn structure. One end of the directional horn structure is a small diameter, and the other end is a large diameter. The small diameter end is connected to the air supply pipe 13, and the large diameter end is installed on the mill housing 1. When the air supply pipe 13 delivers gas into the pressure reducing member, the structure of the pressure reducing member increases and extends from the equipment room to the side of the mill housing, so that the gas pressure gradually decreases after entering it, achieving a pressure reduction effect.

[0046] In some embodiments of the present disclosure, in order to increase the brightness of the operating room, an additional lighting lamp 2 is installed. Figure 1 and 2 As shown, the operating room 101 is equipped with a lighting lamp 2. The lighting lamp 2 can be electrically connected to the controller 8, and the controller 8 can be used to control the lighting lamp on and off.

[0047] In some embodiments of the present disclosure, a power button 10 and an emergency stop button 9 are additionally installed. Figure 1 , 2 As shown, the power button 10 and the emergency stop button 9 are installed on the mill housing 1 near the operation port 1011; the power button 10 is electrically connected to the controller 8; the emergency stop button 9 is electrically connected to the drive motor 4 and the controller 8 respectively, and is used to control the drive motor 4 to stop suddenly.

[0048] The power button 10 is used to supply power to or cut off power to the controller 8 .

[0049] It should be noted that the emergency stop button 9 can be pressed in an emergency to cut off the power supply to the drive motor, causing the drive motor to stop urgently.

[0050] According to the above embodiments, the working mode of the utility model is as follows:

[0051] The driving motor 4 and the vacuum pump 14 are operated by the controller 8. The driving motor 4 drives the driving shaft 41 to rotate, and the driving shaft 41 drives the polishing part 5 to rotate. The vacuum pump 14 extracts the gas in the negative pressure chamber 16, so that the negative pressure chamber 16 forms a negative pressure. The negative pressure chamber 16 extracts the gas in the box body 31 of the dust collecting box 3 through the negative pressure hole 161 and the through hole 36, so that a negative pressure is formed in the box body 31. The box body 31 absorbs the gas on its top, so that a negative pressure is formed above the partition net, and the gas above the partition net is pumped to flow downward.

[0052] After the operator has taken protective measures, the gold to be polished is brought into contact with the polishing head 51 on the polishing piece 5, so that the polishing head polishes the surface of the gold. The dust and particles generated by the polishing are carried to the partition net 104 by the gas in the operating room, and then enter the box body 31 through the partition net 104, and are intercepted by the dust collecting bag 35 in the box body 31. The dust collecting bag collects the dust, particles, gold powder residue and other waste materials generated by polishing.

[0053] When the grinding is finished, the driving motor 4 and the vacuum pump 14 are stopped by the controller 8. The baffle 32 is pulled outward by the handgrip 33, and the baffle 32 drives the box body 31 to separate from the dust collecting groove 103, so that the dust collecting bag can be cleaned to recover the gold powder residue generated by grinding.

[0054] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
