Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a self-heating grinding device. Background Art

[0002] A head refers to a component used to seal the end of a container to isolate the internal and external media. During the processing of the head, the head needs to be polished. Currently, a flap wheel is commonly used as a polishing head to polish the head. First, the flap wheel is installed at the end of the rotating shaft of the polishing mechanism. A mounting plate is fixed on the mounting frame of the polishing mechanism. The height of the mounting plate extends to above the mounting frame. A through hole connected to the rotating shaft is opened in the center of the extended portion of the mounting plate. A pulley is installed on the rotating shaft inside the flap wheel, and a pulley is also installed on the output shaft of the drive motor. The two pulleys are driven by a belt. The drive motor is started, and the pulley on the rotating shaft is driven by the belt to rotate, thereby driving the rotating shaft to rotate, so as to drive the flap wheel to rotate to polish the head. However, the flap wheel generates a lot of heat due to long-term operation. If the temperature is not reduced and the heat is not dissipated in time, it is likely to cause the blades or cloth (the material on the flap wheel) to burn, causing damage to the flap wheel and posing a safety hazard.

[0016] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] like Figure 1-3 As shown, a self-heating grinding device proposed in this embodiment includes a rotating shaft 1, one end of which is equipped with a flap wheel 2 for grinding the head, the other end is rotatably connected to the rotating hole of the extension part of the mounting plate 2, and a pulley 4 is also installed in the middle part, and also includes a heat dissipation structure. The heat dissipation structure includes a plurality of air inlet holes 5 opened on the extension part of the mounting plate 3, and the plurality of air inlet holes 5 are arranged at intervals along the circumference of the rotating hole. Cold air is blown to the flap wheel 2 through the plurality of air inlet holes 5 to cool it down.

[0018] In this way, by providing a plurality of air inlet holes 5 on the extended part of the mounting plate 3, when the flap wheel 2 rotates at high speed, cold air is blown to the flap wheel 2 through the plurality of air inlet holes 5 to cool it down, thereby timely cooling and dissipating the heat of the flap wheel 2, thereby avoiding the flap wheel from being overheated, causing the blades or cloth (the material on the flap wheel) to burn, causing damage to the flap wheel, and also causing safety hazards, thereby extending the service life of the flap wheel.

[0019] Furthermore, if Figure 2 and Figure 3 As shown, the heat dissipation structure also includes a heat dissipation plate 6 fixed on the side of the pulley 4 close to the mounting plate 3. A mounting hole is provided in the center of the heat dissipation plate 6 for the rotating shaft 1 to pass through. A plurality of heat dissipation grooves 7 are opened along the circumference of the side of the heat dissipation plate 6 close to the mounting plate 3. When the flap wheel 2 rotates, the heat dissipation plate 6 also rotates at high speed. At this time, centrifugal force is generated between the heat dissipation plate 6 and the mounting plate 3, and heat is discharged through the heat dissipation grooves 7.

[0020] The servo motor 8 drives the pulley at the output end to rotate, and then drives the pulley 4 on the rotating shaft 1 to rotate through the belt, so as to drive the flap wheel 2 to rotate. At this time, the cold air blows to the center of the flap wheel 2 through multiple air inlet holes 5. At the same time, the heat generated by the flap wheel 2 is guided out by the heat dissipation groove 7, and the hot air is discharged to dissipate the heat of the flap wheel 2. The cooling of the cold air and the heat dissipation of the heat dissipation groove 7 are carried out at the same time, which can dissipate the heat and cool the flap wheel 2 in a timely and rapid manner, avoiding the problem that the flap wheel temperature is too high, causing the blades or cloth (the material on the flap wheel) to burn, causing damage to the flap wheel.

[0021] Furthermore, in order to simplify the processing technology and enhance the structural stability, the heat sink 6 and the pulley 4 are configured as an integrated structure.

[0022] Among them, Figure 3 As shown, the heat dissipation groove 7 is configured as a rectangular groove radially penetrating the heat dissipation plate 6, which can discharge heat to the maximum extent.

[0023] In this embodiment, in order to make the extended portion of the mounting plate 3 better match the heat dissipation plate 6, the upper end of the extended portion of the mounting plate 3 is configured as an arc-shaped structure.
