Description

Technical Field

[0001] The utility model relates to the field of polishing of hardware accessories, and specifically relates to a polishing device for hardware accessories. Background Technique

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical actions to reduce the surface roughness of a workpiece to obtain a bright and flat surface. It is a finishing process that uses a polishing tool and abrasive particles or other polishing media to process the surface of the workpiece. Hardware accessories refer to machine parts or components made of hardware, as well as some small hardware products, such as hinges, hinges, gaskets, pin rods, etc. When processing hardware accessories, it is necessary to polish their surfaces to improve the flatness and brightness of the surface. In traditional hardware accessory polishing equipment, when polishing for a long time, heat will be generated due to the friction between the polishing belt and the accessory. When the temperature of the polishing belt itself is too high, it will not only affect the polishing effect but also affect the service life.

[0003] To solve the above problems, we propose a polishing device for hardware accessories, which is improved for the deficiencies of the existing technology. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the existing technology and provide a polishing device for hardware accessories. To solve the above technical problems, the utility model provides the following technical solutions:

[0005] A polishing device for hardware accessories of the utility model includes a feeding frame. A plurality of rollers are arranged inside the frame of the feeding frame. A vertical plate is also fixed on the side wall of the back of the feeding frame. A rotating rod and a rotating cylinder are connected to the vertical plate through bearings. An electric motor, an air inlet pipe and a duct fan are also fixed on the side of the back of the vertical plate. A driving roller is fixedly connected to the front end of the rotating rod. The output shaft of the electric motor is fixedly connected to the back end of the rotating rod. A hollow roller is fixedly and hermetically communicated with the front end of the rotating cylinder. A polishing belt is sleeved between the driving roller and the hollow roller. The bottom end of the air inlet pipe is inserted into the port on the back of the rotating cylinder, and the upper end of the air inlet pipe is connected to the duct fan. A tensioning mechanism is also arranged on the vertical plate. The tensioning mechanism includes a support plate, a guide rod, a clamping frame, a pressing roller, an adjusting screw and a spring. A support plate is fixed on the front of the vertical plate. Two retractable guide rods are inserted into the support plate. A clamping frame is fixed at the end of the guide rod pointing to the polishing belt. A rotatable pressing roller is arranged inside the clamping frame. An adjusting screw is also threadedly connected to the center of the support plate. A spring is also sleeved on the guide rod.

[0006] Preferably, a plurality of blowing holes are evenly arranged on the hollow roller.

[0007] Preferably, a controller is further provided on the front surface of the vertical plate, and the controller is electrically connected to the motor and the duct fan.

A vertical plate 3 is further fixed on the side wall of the back surface of the feeding frame 1. A rotating rod 4 and a rotating cylinder 5 are connected to the vertical plate 3 through bearings. A motor 9, an air inlet pipe 10 and a pipe blower 11 are further fixed on the side edge of the back surface of the vertical plate 3. The end of the front surface of the rotating rod 4 is fixedly connected with a driving roller 6. The output shaft of the motor 9 is fixedly connected to the end of the back surface of the rotating rod 4. The end of the front surface of the rotating cylinder 5 is fixedly and hermetically communicated with a hollow roller 7. A polishing belt 8 is sleeved between the driving roller 6 and the hollow roller 7. The bottom end of the air inlet pipe 10 is inserted into the port on the back surface of the rotating cylinder 5, and the upper end of the air inlet pipe 10 is connected to the pipe blower 11. A tensioning mechanism is further arranged on the vertical plate 3. The tensioning mechanism includes a support plate 12, a guide rod 13, a clamping frame 14, a squeezing roller 15, an adjusting screw 16 and a spring 17. A support plate 12 is fixed on the front surface of the vertical plate 3. Two slidable guide rods 13 are inserted into the support plate 12. A clamping frame 14 is fixed at one end of the guide rod 13 pointing to the polishing belt 8. A rotatable squeezing roller 15 is arranged inside the clamping frame 14. An adjusting screw 16 is further threadedly connected to the center of the support plate 12. A spring 17 is further sleeved on the guide rod 13, forming the overall structure of the polishing device for hardware fittings. By combining the pipe blower 11, the air inlet pipe 10 and the rotating cylinder 5, air is continuously blown into the hollow roller 7, and the heat on the hollow roller 7 is taken away by the continuous blowing, so that the hollow roller 7 can be quickly cooled. At the same time, the blowing air will also be blown onto the polishing belt 8 through the air blowing holes 18 to blow and dissipate heat from the polishing belt, accelerating the heat dissipation speed of the polishing belt.

[0022] In this embodiment, a plurality of air blowing holes 18 are uniformly arranged on the hollow roller 7, which are used to blow away the heat on the hollow roller 7 and can also blow and dissipate heat from the polishing belt 8.

[0023] In this embodiment, a controller 19 is further arranged on the front surface of the vertical plate 3. The controller 19 is electrically connected to the motor 9 and the pipe blower 11, facilitating the control of the operation of the device.

[0024] In this embodiment, a rubber ring 20 is sleeved and fixed on the rotating roller 2, which can tightly hold the hardware fittings below the hollow roller 7, enabling the hardware fittings to be in close contact with the polishing belt 8 and improving the polishing effect.

[0025] In this embodiment, a sealing ring 21 is fixed on the inner wall of the back port of the rotating cylinder 5, and the bottom end of the air inlet pipe 10 is inserted into the sealing ring 21 to enhance the sealing performance.

[0026] In this embodiment, the pressing roller 15 is directly opposite to the polishing belt 8, facilitating the pressing of the polishing belt 8 to adjust its tightness.

[0027] In this embodiment, the hollow roller 7 is located directly above the material conveying frame 1 to ensure that the hardware fittings can be pushed by the rotating roller 2 below the hollow roller 7.

[0028] Principle and advantages of the present utility model: Connect the controller 19 to the power supply to supply power to the motor 9 and the duct fan 11. Rotate the adjusting screw 16 inward or outward to adjust the tightness of the polishing belt 8. Then turn on the motor 9 and the duct fan 11. The motor 9 drives the driving roller 6 to rotate clockwise at a high speed. The driving roller 6 drives the polishing belt 8 to rotate at a high speed against the hollow roller 7. The duct fan 11 continuously sends air into the air inlet pipe 10, and the air is then sent to the hollow roller 7 through the rotating cylinder 5. Finally, it is blown out from the air blowing holes 18 on the hollow roller 7. The blown air can not only take away the heat on the hollow roller 7 but also be blown onto the polishing belt 8 to dissipate heat by blowing on the polishing belt 8. Then place the hardware fittings on the rotating roller 2 on the left side of the material conveying frame 1, and then push the hardware fittings under the hollow roller 7. When the polishing belt 8 comes into contact with the hardware fittings, the surface of the hardware fittings can be polished. This polishing device for hardware fittings can dissipate heat by blowing on the polishing belt 8, accelerate the heat dissipation speed of the polishing belt 8, is beneficial to extending the continuous polishing time and service life, and can also ensure good polishing effect.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
