During the grinding process, the ground parts need to be cooled and lubricated by spraying water. The existing grinding devices lack a structure that can effectively block water mist. The sprayed water mist can easily splash onto the surface of the product and remain on the product. For products with high cleanliness requirements, water mist can cause product contamination and lead to product defects. Utility Model Content

[0003] The purpose of the utility model is to provide a non-splashing grinding device, which can effectively prevent water mist from splashing onto the product surface during the grinding process, thereby improving the cleanliness and quality of the product.

[0004] A splash-free grinding device comprises a main body, a grinding wheel, an air knife assembly, and a water spray assembly, wherein the main body has a cavity inside, the grinding wheel is rotatably arranged in the cavity, a grinding port is provided on the front side of the cavity, the air knife assembly comprises two air knives arranged opposite to the grinding port, the air outlets of the air knives are inclined toward the cavity, a gap is formed between the two air knives for the product to be processed to slide through and contact the grinding wheel, the surface of the air knife close to the grinding port is recessed inward to form a recessed portion, a shielding convex edge is provided on one side of the recessed portion, the outer periphery of the grinding wheel extends into the recessed portion and is located between the two shielding convex edges, the water spray assembly is provided at both ends of the grinding port, the main body is provided with an air suction unit connected to the cavity, the air suction unit is used to generate negative pressure in the cavity to suck water mist into and discharge the cavity.

[0005] In the above technical solution, a grinding wheel is arranged in a cavity, and two opposing air knives are provided at the grinding opening. The product to be ground can be extended into the gap between the two air knives and contact the grinding wheel for grinding. The air knives blow air on both surfaces of the product through high-pressure airflow, forming an airflow gap between the inside and outside of the cavity. The airflow gap can change the direction of the water mist movement, blowing the water mist into the cavity to prevent the water mist from splashing onto the surface of the external product. At the same time, the high-pressure airflow can also blow water droplets remaining on the edge of the product into the cavity, ensuring the cleanliness of the product surface. The main body is provided with an air suction unit connected to the cavity. The air suction unit can inhale air so that the air pressure inside the cavity is lower than the external air pressure. Combined with the airflow blown by the air knife, a high-suction high-speed air duct is formed, so that the water mist is sucked into the cavity under the action of negative pressure and discharged from the air suction unit, further preventing the water mist from splashing outside the cavity and ensuring the cleanliness of the product surface.

[0006] Furthermore, the air suction unit includes side air suction ports arranged on both sides of the grinding wheel in a radial direction, and a bottom air suction port arranged below the grinding wheel.

[0007] In the above technical solution, the side air intakes are located on opposite sides of the grinding wheel. During grinding, the centrifugal force of the grinding wheel will throw water to both sides of the grinding position. The side air intakes can effectively absorb this part of the water mist, improving the effect of preventing water mist from splashing. The bottom air intake can absorb the running water, thereby quickly draining the water in the cavity.

[0008] Furthermore, the side air intake port is opposite to the outer peripheral surface of the grinding wheel.

[0009] In the above technical solution, the side air intake port is opposite to the outer peripheral surface of the grinding wheel, which can more accurately and quickly absorb the water thrown out by the grinding wheel, thereby improving the water absorption effect.

[0010] Furthermore, the wind knife is provided with a plurality of waist-shaped holes, and the wind knife is in contact with the main body through a connecting piece passing through the waist-shaped holes. The wind knife can slide along the length direction of the waist-shaped holes to adjust the width of the gap.

[0011] In the above technical solution, the air knife can be abutted against the main body via a connector, ensuring the sealing of the cavity. The waist-shaped hole allows the position of the air knife to be adjusted. Adjusting the position of the air knife changes the width of the gap. This not only adapts to products of different thicknesses, improving the applicability of the grinding equipment, but also allows the gap to match the thickness of the products, reducing the area where water can splash out of the cavity.

[0012] Furthermore, the water outlet of the water spray assembly is located in the recessed portion.

[0013] In the above technical solution, the water spray assembly is arranged in the recessed portion, which can make the water spray position closer to the outside of the cavity relative to the grinding position, so that the water spray angle can be directed toward the inside of the cavity, further preventing water from splashing out of the cavity.

[0014] Furthermore, a partition is provided in the cavity, and the partition includes an arc-shaped portion, and the arc-shaped portion is close to the outer periphery of the grinding wheel.

[0015] In the above technical solution, by providing a partition, and arranging the partition at the arc portion close to the outer periphery of the grinding wheel, the volume of the cavity can be reduced, which facilitates the formation of negative pressure in the suction unit and improves the water absorption efficiency.

[0016] Furthermore, the water spray assembly includes at least two water outlets, and at least two of the water outlets are inclined toward the inner side of the cavity.

[0017] In the above technical solution, the water outlet of the water spray assembly is provided with at least two water outlets, which can improve the cooling efficiency and make the cooling range more comprehensive. The water outlets are inclined toward the inside of the cavity, which can make the water spray toward the inside of the cavity and reduce the possibility of water splashing out of the cavity.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: a grinding wheel is arranged in a cavity, and two opposite air knives are arranged at the grinding port. The product to be ground can be extended into the gap between the two air knives and contacted with the grinding wheel for grinding. The air knives blow air on both surfaces of the product through high-pressure airflow, forming an airflow gap between the inside and outside of the cavity. The airflow gap can change the direction of the water mist movement, blowing the water mist into the cavity to prevent the water mist from splashing onto the surface of the external product. At the same time, the high-pressure airflow can also blow water droplets remaining on the edge of the product into the cavity, ensuring the cleanliness of the product surface. The main body is provided with an air suction unit connected to the cavity. The air suction unit can inhale air so that the air pressure inside the cavity is lower than the external air pressure. Combined with the airflow blown by the air knife, a high-suction high-speed air duct is formed, so that the water mist is sucked into the cavity under the action of negative pressure and discharged from the air suction unit, further preventing the water mist from splashing outside the cavity and ensuring the cleanliness of the product surface.

DETAILED DESCRIPTION

[0026] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein.

[0027] Please refer to Figures 1 to 5 In a preferred embodiment, the splash-free grinding device of the present invention mainly includes a main body 1, a grinding wheel 2, a wind knife 31 assembly 3, and a water spray assembly 4. The main body 1 has a cavity 11 inside, the grinding wheel 2 is rotatably arranged in the cavity 11, and a grinding port is provided on the front side of the cavity 11. The wind knife 31 assembly 3 includes two wind knives 31 arranged opposite to the grinding port, and a gap 314 is formed between the two wind knives 31 for the product 6 to be processed to slide through and contact the grinding wheel 2. The water spray assembly 4 is provided at at least one end of the grinding port. The main body 1 is provided with an air suction unit 5 connected to the cavity 11. The air suction unit 5 is used to generate negative pressure in the cavity 11 to suck water mist into and discharge it from the cavity 11.

[0028] The cavity 11 is located within the main body 1 and communicates with the outside only through the gap 314 between the two air blades 31. This ensures the sealing of the cavity 11, prevents water mist from splashing to the outside, and facilitates the formation of negative pressure in the suction unit 5. The grinding wheel 2 is disposed within the cavity 11. As will be understood, the grinding wheel 2 is connected to an external rotary drive device, which drives the grinding wheel 2 to rotate, thereby performing grinding. The rotary drive device can be an existing rotary drive device.

[0029] Two air knives 31 are arranged opposite to each other at the grinding mouth. The air knives 31 can be high-pressure air knives 31. The product 6 to be ground can be extended into the gap 314 between the two air knives 31 and contact with the grinding wheel 2 for grinding. The air knives 31 blow air on both surfaces of the product 6 through high-pressure airflow, forming an airflow gap between the inside and outside of the cavity 11. The airflow gap can change the direction of movement of the water mist and blow the water mist into the inside of the cavity 11 to prevent the water mist from splashing onto the surface of the external product 6. At the same time, the high-pressure airflow can also blow the water droplets remaining on the edge of the product 6 into the cavity 11 to ensure the cleanliness of the surface of the product 6.

[0030] The main body 1 is provided with an air suction unit 5 connected to the cavity 11. The air suction unit 5 can inhale air so that the air pressure inside the cavity 11 is lower than the external air pressure. Combined with the air flow blown out by the wind knife 31, a high-suction and high-speed air duct is formed, so that the water mist is sucked into the cavity 11 under the action of negative pressure and discharged from the air suction unit 5, further preventing the water mist from splashing to the outside of the cavity 11 and ensuring the cleanliness of the surface of the product 6.

[0031] Please refer to Figure 3The air intake unit 5 includes side air intake ports 51 disposed on opposite radial sides of the grinding wheel 2, and a bottom air intake port 52 disposed below the grinding wheel 2. Both the side air intake ports 51 and the bottom air intake port 52 are connected to an external negative pressure device. The side air intake ports 51 are disposed on opposite sides of the grinding wheel 2. During grinding, the centrifugal force of the grinding wheel 2 will throw water to both sides of the grinding position. This water mist can be effectively sucked in through the side air intake ports 51, thereby improving the effect of preventing water mist from splashing.

[0032] In this embodiment, the side air intake 51 is opposite to the outer circumference of the grinding wheel 2, thereby more accurately and quickly sucking in water thrown out by the grinding wheel 2, thereby improving the water absorption effect. The bottom air intake 52 is located below the projection of the grinding wheel 2 and can suck in water flowing out of the cavity 11, thereby quickly draining the water out of the cavity 11.

[0033] Please refer to Figure 4 The surface of the air knife 31 near the grinding opening is recessed inward to form a recessed portion 311. A shielding ridge 312 is provided on one side of the recessed portion 311. The recessed portions 311 of the two air knives 31 are symmetrically distributed on both sides of the gap 314. The outer periphery of the grinding wheel 2 extends into the recessed portion 311 and is located between the two shielding ridges 312. Exemplarily, the recessed portion 311 is open on one side near the gap 314, so that the recessed portion 311 is connected to the gap 314. A boss is formed around the recessed portion 311, and the surface of the boss is in close contact with the main body 1. The recessed portions 311 of the two air knives 31 cooperate to form a space protruding from the cavity 11. The grinding wheel 2 can extend into the space, so that the outer periphery of the grinding wheel 2 can be closer to the outside of the cavity 11, which is convenient for grinding the product 6. A shielding ridge 312 is provided on one side of the recessed portion 311 . When the grinding wheel 2 is located in the recessed portion 311 , the shielding ridge 312 can shield the grinding area from the upper and lower sides of the grinding wheel 2 to prevent water from splashing out.

[0034] In this embodiment, the water outlet of the water spray assembly 4 is located in the recessed portion 311. By arranging the water spray assembly 4 in the recessed portion 311, the water spraying position can be closer to the outside of the cavity 11 relative to the grinding position, so that the angle of the water spray can be directed toward the inside of the cavity 11, further preventing water from splashing out of the cavity 11.

[0035] The wind knife 31 is provided with a number of waist-shaped holes 313. The wind knife 31 is in contact with the main body 1 through a connector provided through the waist-shaped holes 313. The wind knife 31 can slide along the length direction of the waist-shaped holes 313 to adjust the width of the gap 314. Exemplarily, the connector can adopt an existing threaded connector, such as a screw. The main body 1 is provided with a threaded hole corresponding to the waist-shaped hole 313. The screw passes through the waist-shaped hole 131 and is threadedly connected to the main body 1. The wind knife 31 is in contact with the main body 1 through the connector, which can ensure the sealing of the cavity 11. By providing the waist-shaped holes 313, the position of the wind knife 31 is adjustable. Adjusting the position of the wind knife 31 can change the width of the gap 314. On the one hand, it can adapt to products 6 of different thicknesses and improve the applicability of the grinding equipment; on the other hand, it can match the thickness of the product 6 in the gap 314 and reduce the area where water can splash out of the cavity 11.

[0036] A partition 12 is provided within the cavity 11. The partition 12 includes an arcuate portion 121, which is located near the outer periphery of the grinding wheel 2. For example, both ends of the partition 12 are connected to the inner surfaces of the two sides of the cavity 11, and both ends of the partition 12 are located near the side suction port 51. The arcuate portion 121 is coaxial with the grinding wheel 2 and is located near the outer periphery of the grinding wheel 2. This reduces the volume of the cavity 11, facilitates the formation of negative pressure in the suction unit 5, and improves water absorption efficiency.

[0037] In this embodiment, two water spray assemblies 4 are provided, positioned opposite each other at either end of the grinding opening. Each water spray assembly 4 has at least two water outlets, which improves cooling efficiency and provides a more comprehensive cooling coverage. The water outlets are angled toward the interior of the cavity 11, directing water toward the interior and minimizing the risk of water splashing out of the cavity 11.

[0038] As a preferred embodiment, the air outlet of the wind knife 31 is tilted toward the cavity 11, so that the airflow forms an angle with the surface of the product 6, which is conducive to blowing the water droplets remaining on the edge of the product 6 into the cavity 11 and discharging them.

[0039] To facilitate understanding of this technical solution, the following describes its working principle, which includes the following steps:

[0040] S1, insert the edge of the product 6 to be ground into the gap 314 between the two air knives 31, and drive the product 6 to move in a direction parallel to the extension direction of the gap 314;

[0041] S2, grinding the edge to be ground of the product 6 by the grinding wheel 2;

[0042] S3, the water spraying component 4 sprays water to the grinding part;

[0043] S4, the two air knives 31 blow air to the two surfaces of the product 6 at the same time, with the blowing direction tilted toward the inside of the cavity 11;

[0044] S5 , generating negative pressure in the cavity 11 through the air suction unit 5 , sucking the water mist into the cavity 11 , and then discharging the water mist from the cavity 11 through the air suction unit 5 .
