[0026] For examples, please refer to the attached Figure 1-5 A polishing device for refrigeration copper pipes, comprising a polishing frame 10, the polishing frame 10 is a cavity structure, and a through slot 11 is provided at the middle end of the polishing frame 10, a copper pipe conveying mechanism 40 is installed in the through slot 11 area, a polishing mechanism 20 is installed on the top of the polishing frame 10, and the polishing mechanism 20 comprises a cylinder 21 installed on the top of the polishing frame 10, a wheel frame 24 installed on the output rod of the cylinder 21, a polishing wheel 23 installed at the bottom of the wheel frame 24, and a first motor 25 installed on one side of the wheel frame 24 and connected to the wheel center of the polishing wheel 23;

[0027] A negative pressure dust suction device 30 is installed at the inner bottom of the polishing table 10, and the negative pressure dust suction device 30 includes a dust guide plate 31 installed inside the polishing table 10 at the bottom area of ​​the through slot 11, and a negative pressure fan 32 installed at the bottom of the dust guide plate 31. The dust guide plate 31 is provided with a guide slot 34 with the top inclined toward the bottom center, and a collection bag 33 is installed between the bottom of the guide slot 34 and the negative pressure fan 32.

[0028] For details, please refer to the attached Figure 1 and attached Figure 2 The copper tube conveying mechanism 40 includes an L-shaped frame 41 installed at the bottom of both sides of the through slot 11 and two conveying shaft rollers 42 rotatably connected and installed in the L-shaped frame 41. The L-shaped frame 41 is a hollow structure. Two transmission wheels 43 connected to the two conveying shaft rollers 42 are installed in the L-shaped frame 41, a transmission belt 44 sleeved on the two transmission wheels 43, and a second motor 45 installed on the outside of the L-shaped frame 41 and connected to one of the transmission wheels 43;

[0029] In this embodiment, it should be noted that the electrical components of the device are electrically connected to a conventional PLC controller, and the two conveying shaft rollers 42 and the polishing wheel 23 have a certain inclination angle with the horizontal plane. The conveying shaft rollers 42 and the polishing wheel 23 are parallel to each other, so that the copper tube moves toward the other end along the conveying shaft rollers 42 during transportation. Through the operation of the second motor 45, in conjunction with the transmission of the transmission wheel 43 and the transmission belt 44, the refrigeration copper tube located on the conveying shaft roller 42 can be transported as the conveying shaft roller 42 rotates, and polishing is completed in conjunction with the polishing wheel 23.

[0030] For details, please refer to the attached Figure 3 and attached Figure 4 A lifting plate 22 is installed between the output rod of the cylinder 21 and the wheel frame 24, and sliders 26 are provided on both sides of the lifting plate 22. The inner walls of both sides of the polishing stand 10 are provided with slide grooves 14 adapted to the sliders 26;

[0031] In this embodiment, it should be noted that when the cylinder 21 is operating, the slider 26 on the side of the lifting plate 22 will slide in the slide groove 14, thereby increasing the stability of the polishing wheel 23 when it is lifted and lowered, making it easier for the polishing wheel 23 to polish the copper tube.

[0032] For details, please refer to the attached Figure 4 , two electrically controlled fans 50 are installed on the lifting plate 22, and the wind direction of the electrically controlled fans 50 is toward the bottom of the polishing stand 10;

[0033] In this embodiment, it should be noted that the wind blown by the electrically controlled fan 50 is directed toward one end of the negative pressure dust suction device 30 , so that the dust generated during polishing is blown into the guide slot 34 .

[0034] For details, please refer to the attached Figure 1 The bottom of both sides of the polishing stand 10 are both installed with a fixing seat 13, and the fixing seat 13 is provided with two positioning holes;

[0035] In this embodiment, it should be noted that by installing a positioning pin in the fixing hole on the fixing seat 13, the device can be fixed on the table.

[0036] Furthermore, a notch is provided at the front side of the polishing stand 10, and a closing door panel 12 is rotatably connected to the front side of the polishing stand 10 through a hinge;

[0037] A fan cover is provided on the outside of the negative pressure fan 32, and threaded sleeves 35 are rotatably connected and installed on the top and bottom of the collecting bag 33. The threaded sleeve 35 at the top is connected to the inside of the collecting bag 33, and the collecting bag 33 is connected to the bottom of the guide slot 34 and the top of the fan cover through two threaded sleeves 35 respectively through internal and external threads.

[0038] In the present embodiment, it should be noted that openings are arranged on the top and the bottom of the fan cover. The top opening is smaller and can be connected to the threaded sleeve 35, while the threaded sleeve 35 at the bottom of the collecting bag 33 is not interconnected with the collecting bag 33, thereby ensuring that the wind generated by the negative pressure fan 32 passes through the collecting bag 33, while the dust cannot pass through the collecting bag 33, thereby effectively collecting the dust generated during the polishing of the refrigeration copper tube; subsequently, after opening the closed door panel 12, the threaded sleeve 35 can be rotated to disassemble the collecting bag 33, and then the dust in the collecting bag 33 can be cleaned.

[0039] The specific operation mode of the utility model is as follows:

[0040] First, place the refrigeration copper tube on the conveying shaft roller 42, then start the cylinder 21 to operate to lower the polishing wheel 23, so that the bottom of the polishing wheel 23 contacts one end of the refrigeration copper tube, and then start the first motor 25 and the second motor 45. Through the operation of the second motor 45, in conjunction with the transmission of the transmission wheel 43 and the transmission belt 44, the refrigeration copper tube on the conveying shaft roller 42 can be transported as the conveying shaft roller 42 rotates, and the operation of the first motor 25 can enable the polishing wheel 23 to polish the copper tube. At the same time, the negative pressure fan 32 operates, and the suction force generated passes through the collection bag 33 to absorb the dust falling in the dust guide plate 31 area, so that the dust is sucked into the collection bag 33 for collection.

[0041] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
