Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-6 , the present invention provides a technical solution: a grinding device for producing high thermal conductivity and heat dissipation solder resist ink, including:

[0041] A cylinder body 1, with a feed inlet 2 and a slag discharge port 3 provided at its end, and a discharge port 4 is opened on the side wall of the cylinder body 1;

[0043] A filter cylinder 7, which is fixedly connected inside the cylinder body 1, and a finished product bin 8 is formed between the filter cylinder 7 and the inner wall of the cylinder body 1, and the discharge port 4 communicates with the finished product bin 8;

[0044] A flexible swing cooling and stirring mechanism 9, which is arranged inside the cylinder body 1 and connected to the rotating shaft 5, and the flexible swing cooling and stirring mechanism 9 communicates with the two collecting grooves 6;

[0045] A cooling coil 10, which is arranged inside the finished product bin 8 and wound around the filter cylinder 7;

[0046] A driving motor 11, which is fixedly connected to the end of the cylinder body 1, and the driving motor 11 is connected to and drives the rotating shaft 5;

[0047] The flexible swing cooling and stirring mechanism 9 includes multiple flexible cooling tubes 91, multiple sets of buffer traction mechanisms 92, multiple sets of magnetic swing mechanisms 93, and a flexible driving mechanism 94. The multiple flexible cooling tubes 91 are arranged in an annular array along the axis of the rotating shaft 5. The opposite ends of the flexible cooling tubes 91 are respectively connected to the two manifolds 6. The multiple sets of buffer traction mechanisms 92 are arranged in a straight line and slidably connected to the rotating shaft 5. The multiple sets of magnetic swing mechanisms 93 are arranged on the multiple flexible cooling tubes 91 and the filter cylinder 7, and the multiple sets of magnetic swing mechanisms 93 are arranged in a straight line. The buffer traction mechanism 92 is located between two adjacent sets of magnetic swing mechanisms 93. The flexible driving mechanism 94 is installed on the rotating shaft 5, and the flexible driving mechanism 94 is connected to the multiple flexible cooling tubes 91. The coolant flows into the multiple flexible cooling tubes 91 from one of the manifolds 6. After the multiple flexible cooling tubes 91 come into contact with the mixture in the cylinder 1, the heat is transferred to the coolant. The heat-absorbed coolant converges into the other manifold 6 and is discharged, achieving the effect of uniform cooling. The multiple sets of magnetic swing mechanisms 93 and the flexible driving mechanism 94 act on the multiple flexible cooling tubes 91 from different directions, causing the multiple flexible cooling tubes 91 to swing during rotation, thereby dispersing the agglomerated mixture and making the zirconia beads collide violently with each other, so as to enhance the grinding effect and improve the grinding efficiency. The multiple sets of buffer traction mechanisms 92 can adapt to the multi-directional swing of the flexible cooling tubes 91 while buffering and traction the multiple flexible cooling tubes 91;

[0048] The buffer traction mechanism 92 includes a sliding sleeve 921 and multiple hydraulic buffers 922. The sliding sleeve 921 is slidably connected to the rotating shaft 5. The multiple hydraulic buffers 922 are fixedly connected to the sliding sleeve 921. The multiple flexible cooling tubes 91 respectively pass through the ends of the multiple hydraulic buffers 922. The sliding sleeve 921 is on the rotating shaft 5, enabling the hydraulic buffers 922 to adapt to the axial swing while traction the flexible cooling tubes 91. The telescoping of the hydraulic buffers 922 enables the hydraulic buffers 922 to adapt to the radial swing while traction the flexible cooling tubes 91, ensuring the stability of the structure;

[0049] An annular chute 12 is formed on the rotating shaft 5. A support ring 13 is arranged on the sliding sleeve 921. The support ring 13 is slidably connected to the annular chute 12, ensuring the smooth sliding of the sliding sleeve 921 and also being able to limit the swinging and sliding of the sliding sleeve 921;

[0050] The magnetic swing mechanism 93 includes a plurality of first magnetic blocks 931 and a plurality of second magnetic blocks 932. The plurality of first magnetic blocks 931 are respectively connected to a plurality of flexible cooling tubes 91, and the plurality of second magnetic blocks 932 are connected to the filter cartridge 7. The first magnetic blocks 931 magnetically adsorb the second magnetic blocks 932. While the rotating shaft 5 drives the plurality of flexible cooling tubes 91 to rotate, the first magnetic blocks 931 and the second magnetic blocks 932 are alternately adsorbed, causing the positions of the flexible cooling tubes 91 to change, so that different positions inside the cylinder 1 can be stirred, and the stirring effect is uniform.

[0051] The flexible driving mechanism 94 includes a first support plate 941, a second support plate 942 and an annular airbag 943. The first support plate 941, the second support plate 942 and the annular airbag 943 are all fixedly connected to the rotating shaft 5. The annular airbag 943 is located between the first support plate 941 and the second support plate 942. The first support plate 941 and the second support plate 942 both extend to the inner wall of the cylinder 1. A plurality of flexible cooling tubes 91 respectively pass through the first support plate 941, the annular airbag 943 and the second support plate 942. The plurality of flexible cooling tubes 91 are fixedly connected to the annular airbag 943 and the second support plate 942. A vacuum pump 14 is provided at the end of the cylinder 1. The annular airbag 943 is communicated with the vacuum pump 14 through a solenoid valve. Under the control of the solenoid valve, the vacuum pump 14 repeatedly fills and discharges the annular airbag 943. During the deflation process of the annular airbag 943, it will contract, and the contracting annular airbag 943 pulls the plurality of flexible cooling tubes 91, causing the flexible cooling tubes 91 to be straightened and their positions to change, so that different positions inside the cylinder 1 can be stirred, and the stirring effect is uniform.

[0052] Pulley 15 is provided on both the rotating shaft 5 and the output end of the driving motor 11, and the two pulleys 15 are connected by a synchronous belt 16, which is convenient for the driving connection of the driving motor 11 to the rotating shaft 5.

[0053] Both opposite ends of the cooling coil 10 extend to the outside of the cylinder 1, which is convenient for connecting the cooling circulation system.

[0054] Working principle: First, open the feed inlet 2 to inject zirconia beads and the ink to be ground into the barrel body. The two ends of the cooling coil 10 are connected to the cooling circulation system. The coolant enters the cooling coil 10 to take away the heat in the finished product bin 8. The collecting grooves 6 at both ends of the rotating shaft 5 are connected to the cooling circulation system. The coolant enters the flexible cooling pipe 91 to take away the heat in the cylinder body 1, making the cooling of the device sufficient and the cooling efficiency high. Secondly, the driving motor 11 rotates. Under the driving action of the belt pulley 15 and the synchronous belt 16, the rotating shaft 5 rotates at a high speed. Multiple flexible cooling pipes 91, multiple first magnetic blocks 931 connected to the flexible cooling pipes 91, the first support plate 941, the second support plate 942 and the annular airbag 943 will all rotate accordingly. The first magnetic blocks 931 and the second magnetic blocks 932 are alternately adsorbed to cause the position change of the flexible cooling pipe 91. Under the control of the solenoid valve, the vacuum pump 14 repeatedly fills and discharges the annular airbag 943. During the deflation process of the annular airbag 943, it will contract. The contracting annular airbag 943 pulls multiple flexible cooling pipes 91, making the flexible cooling pipes 91 straighten and produce position changes, so as to stir different positions in the cylinder body 1, make the multiple flexible cooling pipes 91 swing during rotation, and then disperse the agglomerated mixture and cause the zirconia beads to violently collide with each other to enhance the grinding effect. Then, the sliding sleeve 921 is on the rotating shaft 5, so that the oil pressure buffer 922 adapts to the axial swing while pulling the flexible cooling pipe 91. The telescopic movement of the oil pressure buffer 922 enables the oil pressure buffer 922 to adapt to the radial swing while pulling the flexible cooling pipe 91. Finally, the ink enters the finished product bin 8 under the filtering action of the filter cylinder 7. Open the discharge port 4 for unified discharging and open the slag discharge port 3 for unified slag discharge.
