When the material arrives at the material sorting disc group 23, the cutting blade 232 is driven to rotate synchronously by the spiral extruding roller 22, and the material is extruded into the through hole on the corresponding cutting disc 231 by the cutting blade 232, thereby using the cutting blade 232 breaks the air bubbles contained in the material to avoid the air bubbles in the material causing deformity of the cut particles, ensuring the integrity of the cutting;

And when the material is extruded by the material distribution disc 24, the rotating motor drives the rotating shaft 73 to rotate, and the rotating shaft 73 rotates to drive the fixed disc 74, the cutter head 75 and the blade 76 to rotate synchronously, thereby utilizing the blade 76 to cut the extruded material to form particles At the same time, the water ring 72 sprays cooling water to cool down the material, helping the material to cool and solidify quickly;

When the knife bar 76 cuts the material, along with the rotation of the cutter head 75, the first tooth block 77 on the knife bar 76 meshes with the second tooth block 78 on the sleeve 79 to rotate, thereby driving the knife bar 76 to move along the cutter head.

Finally, the cut material particles are discharged from the discharge pipe 710 under the action of the water flow from the water ring 72 .

Please refer to Fig. 4 and Fig. 5, the inside of the second tooth block 78 is provided with a lubricating mechanism 8, and the lubricating mechanism 8 includes a pressure plate 81 movably connected to the contact surface of the second tooth block 78 and the first tooth block 77, so A seepage plate 82 is fixedly connected to the inside of the second tooth block 78, and a first spring 83 is fixedly connected between the seepage plate 82 and the pressure plate 81, and a unidirectional spring 83 is fixedly connected between the second tooth block 78 and the sleeve 79. Valve 84, an oil injection port 85 is opened on the left side of the second tooth block 78, and the inside of the sleeve 79 is filled with lubricating oil;

The elastic force of the first spring 83 is greater than the frictional force between the pressure plate 81 and the second tooth block 78, and the oil injection port 85 is provided with a pressure valve inside, and the pressure of the pressure valve is lower than that of the pressure plate 81 to compress to the second tooth block 78 hydraulic pressure generated internally.

Specifically, when the first tooth block 77 is in contact with the second tooth block 78, the first tooth block 77 and the second tooth block 78 will press each other to generate force, and the pressing plate 81 on the second tooth block 78 is subjected to the first tooth block 78.

Specifically, by opening the groove 86 on the inner wall of the cutting cover 71, and the end of the knife strip 76 stretches into the inside of the groove 86, since the right side of the collodion cotton 87 is attached to the right inner wall of the groove 86 in the initial state Therefore, the collodion removal 87 forms a clamping package on the knife strip 76, so that the knife strip 76 rubs against the collodion 87 when rotating, thereby utilizing the collodion removal 87 to scrape off the material adhered to the surface of the knife strip 76 to avoid The sharpness of the blade 76 is reduced due to the wrapping of the material. At the same time, the groove 86 is filled with the collodion remover 87, which can prevent the cut particles from falling into the groove 86 and hinder the rotation of the blade 76;

On this basis, when the blade 76 rotates through the groove 86, the blade 76 squeezes the glue removal cotton 87 at the contact position, so that the glue removal cotton 87 is squeezed and shrinks, so that the hollow volume on the left side of the cutting cover 71 is shrink, and then make the hollow pressure increase, use the pressure to extrude the lubricating oil in the hollow, after the lubricating oil is extruded, it is absorbed by the collodion 87, and with the rotation of the blade 76, the lubricating oil can be removed by the collodion 87 Apply evenly on the surface of the blade 76, realize the lubrication of the surface of the blade 76, reduce the adhesion between the blade 76 and the material, thereby reducing the occurrence of wire drawing, and when the lubricating oil in the hollow is reduced, the Under the action of the second spring 89, the pressure stabilizing plate 88 is moved to the direction of the collodion removal 87, so that the lubricating oil between the stabilizing plate 88 and the collodion 87 is always in a full state, ensuring that the hollow interior is filled with lubricating oil. The partial pressure is constant, so that the lubricating oil can be ejected stably after the collodion 87 is squeezed.

working principle

When the material arrives at the material sorting disc group 23, the cutting blade 232 is driven to rotate synchronously by the spiral extruding roller 22, and the material is extruded into the through hole on the corresponding cutting disc 231 by the cutting blade 232, thereby using the cutting blade 232 breaks the air bubbles contained in the material to avoid the air bubbles in the material causing deformity of the cut particles, ensuring the integrity of the cutting;

And when the material is extruded by the material distribution disc 24, the rotating motor drives the rotating shaft 73 to rotate, and the rotating shaft 73 rotates to drive the fixed disc 74, the cutter head 75 and the blade 76 to rotate synchronously, thereby utilizing the blade 76 to cut the extruded material to form particles At the same time, the water ring 72 sprays cooling water to cool down the material, helping the material to cool and solidify quickly;

When the knife bar 76 cuts the material, along with the rotation of the cutter head 75, the first tooth block 77 on the knife bar 76 meshes with the second tooth block 78 on the sleeve 79 to rotate, thereby driving the knife bar 76 to move along the cutter head. The outer side of 75 rotates so that the blade 76 is displaced when cutting the material, and sliding cutting is performed on the basis of the original pressure cutting, thereby reducing the force of the blade 76 on the material and making the blade 76 cut the material more easily. It avoids the deformation of the material under force, and ensures the flatness of the knife edge when the material is granulated. Finally, the cut material particles are discharged from the discharge pipe 710 under the action of the water jet from the water ring 72;

When the first tooth block 77 is in contact with the second tooth block 78, the first tooth block 77 and the second tooth block 78 will press each other to generate force, and the pressure plate 81 on the second tooth block 78 is pressed by the first tooth block 77 shrinks to the inside of the second tooth block 78 after being squeezed, so that the internal volume of the second tooth block 78 is reduced, thereby increasing the internal pressure of the second tooth block 78, and the lubricating oil inside the second tooth block 78 is sprayed through the pressure. The oil port 85 is extruded and sprayed on the surface of the blade 76, which realizes the lubrication of the surface of the blade 76, reduces the adhesion between the blade 76 and the material, thereby reducing the occurrence of wire drawing, and then acts as the first tooth block 77 is separated from the second tooth block 78, and the pressure plate 81 is pushed back under the action of the first spring 83, and the suction force is generated when the pressure plate 81 is reset, so that the lubricating oil inside the sleeve 79 is sucked into the inside of the second tooth block 78. The function of automatic material replenishment inside the second tooth block 78, it should be noted that since the second tooth block 78 and the sleeve 79 are connected through a one-way valve 84, the lubricating oil in the second tooth block 78 will not flow back to the Inside the sleeve 79.
