[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model.

[0020] like Figure 1 As shown, this embodiment provides a cooling device for cooling products during the polishing process. The device includes a base 1 and a spraying device 3. The spraying device 3 includes an air source nozzle 31, a nozzle 32, and a polishing liquid suction pipe 33. The air source nozzle 31 includes a large-diameter section, a variable-diameter section, and a small-diameter section connected in sequence. The end of the large-diameter section is connected to a high-pressure air source (not shown in the figure). The nozzle 32 is connected to the end of the small-diameter section to spray polishing liquid. One end of the polishing liquid suction pipe 33 is connected to the small-diameter section, and the other end is connected to a polishing liquid container 6. A lifting mechanism 4 is provided on the base 1, and the nozzle 32 is mounted on the lifting mechanism 4. The lifting mechanism 4 is used to move the nozzle 32 up and down relative to the polishing device 2.

[0021] The cooling device in this embodiment includes a spraying device 3 designed according to Bernoulli's principle. This spraying device 3 utilizes changes in gas velocity to generate negative pressure for automatic spraying of polishing liquid. During operation, when the compressed gas in the high-pressure gas source passes through the diameter-changing section of the gas source nozzle 31, the gas velocity increases due to the change in pipe diameter. According to Bernoulli's principle, when the gas velocity increases, the pressure decreases, thus creating a negative pressure absorption zone at the diameter-changing section of the gas source nozzle 31. This allows the polishing liquid to be drawn from the polishing liquid container 6 into the gas source nozzle 31 and sprayed onto the polishing wheel 22 or the product surface along with the gas. On the surface, the sprayed polishing liquid is in the form of a mist and is sprayed evenly, which saves polishing liquid and makes it easier to clean the working environment. On the other hand, the base 1 is equipped with a lifting mechanism 4, which drives the nozzle 32 to move up and down, so that the polishing device 2 has sufficient operating space during the processing. The overall structure is simple and stable and reliable in use. Therefore, while the polishing device 2 polishes the product, the spraying device 3 can be used to spray polishing liquid on the product to cool it down in time, which can effectively avoid deformation or cracking caused by overheating of the product surface during the polishing process and improve the product yield.

[0022] In this embodiment, the gas source nozzle 31 is made of a soft material, such as a metal hose. This not only effectively reduces the flow resistance of the gas, but also meets the usage requirements of various layout methods.

[0023] To further improve the spraying effect of the polishing liquid, in this embodiment, the polishing liquid suction pipe 33 is preferably set at the position of the small diameter section of the air source nozzle 31 close to the variable diameter section of the air source nozzle 31.

[0024] In order to achieve the spraying and pausing of polishing fluid, this embodiment is equipped with a solenoid valve (not shown in the figure) on the air source nozzle 31. The solenoid valve controls the opening and closing of the high-pressure air source, thereby realizing the spraying and pausing of polishing fluid.

[0025] In order to adjust the spray volume of polishing liquid, a pressure regulating valve (not shown in the figure) is provided on the air source nozzle 31 in this embodiment. The pressure of the high-pressure air source is adjusted by the pressure regulating valve, thereby realizing the adjustment of the spray volume of polishing liquid.

[0026] In this embodiment, a one-way valve (not shown in the figure) is provided on the polishing liquid suction pipe 33. This configuration can prevent the polishing liquid in the polishing liquid suction pipe 33 from flowing back into the polishing liquid container 6 when the high-pressure air source is turned off, so that the polishing liquid can be sprayed in time when the high-pressure air source is turned on again, thereby improving work efficiency.

[0027] The lifting mechanism 4 in this embodiment includes a lifting drive 41 and a nozzle seat 42. The lifting drive 41 is mounted on the base 1, and the nozzle 32 is fixedly mounted on the nozzle seat 42. This configuration enables lifting-type spraying of polishing liquid, or when polishing liquid needs to be sprayed, the lifting drive 41 raises the nozzle 32, and when polishing liquid is not needed, the lifting drive 41 retracts the nozzle 32, thereby saving internal space of the cooling equipment and improving the space utilization rate of the equipment.

[0028] Preferably, the lifting drive component 41 is a telescopic cylinder, but an electric cylinder or a hydraulic cylinder can also be used, depending on the actual needs. This embodiment does not impose any restrictions on this.

[0029] To meet the usage needs of different products, this embodiment provides a position adjustment structure between the lifting drive component 41 and the base 1.

[0030] Specifically, the position adjustment structure includes an adjustment seat 51 and a locking bolt 52. The adjustment seat 51 is provided with an adjustment elongated hole, and the locking bolt 52 passes through the adjustment elongated hole and is threaded onto the base 1. The lifting drive component 41 is mounted on the adjustment seat 51. During adjustment, the position of the adjustment seat 51 can be adjusted by loosening the locking bolt 52, thereby realizing the position adjustment of the nozzle 32 to meet the usage requirements of different products.

[0031] In this embodiment, the nozzle holder 42 includes a base 421 connected to the lifting drive member 41 and a pressure plate 422 detachably connected to the base 421. The base 421 is provided with a nozzle mounting groove, and the nozzle 32 is fixed in the nozzle mounting groove by the pressure plate 422. Of course, the nozzle holder 42 can also adopt other structures that can fix the nozzle 32, and the specific design can be selected according to actual needs. This embodiment does not limit this.

[0032] The polishing device 2 in this embodiment includes a rotary drive 21 and a polishing wheel 22. The rotary drive 21 is mounted on the base 1, and the polishing wheel 22 is mounted on the rotary drive 21. The rotary drive 21 is used to drive the polishing wheel 22 to rotate, and the polishing wheel 22 is used to polish the product.

[0033] Preferably, the rotary drive 21 is a motor, and the polishing wheel 22 is mounted on the rotating shaft of the motor.

[0034] During operation, the rotary drive 21 drives the polishing wheel 22 to rotate and polish the product. At the same time, the air source nozzle 31 generates negative pressure through the change of gas flow rate, which draws the polishing liquid from the polishing liquid container 6 through the polishing liquid suction pipe 33. The drawn polishing liquid is then sprayed onto the product through the nozzle 32 to cool the product.

[0035] The above describes one embodiment of the cooling device of this utility model in detail. Many other embodiments are also described but will not be elaborated upon here. In summary, the cooling device of this utility model can promptly cool down products during polishing, solving the problem of deformation or cracking caused by overheating of the product surface during polishing, and improving product yield.

[0036] This utility model is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort shall fall within the protection scope of this utility model.
