[0027] When in use, the polyurethane raw material is poured into the inner cavity of the upper part of the grinding barrel 3. Under the action of the grinding component 4, the polyurethane raw material slowly and evenly passes through the grinding channel between the grinding barrel 3 and the grinding component 4, so that the polyurethane raw material is ground under the action of the grinding barrel 3 and the grinding component 4, and the ground polyurethane raw material is discharged through the discharge pipe 2 at the bottom.
[0028] like Figure 2-Figure 7 As shown, the grinding assembly 4 includes a fixed block 41, the lower surface of the fixed block 41 is fixedly connected to the upper surface of the support frame 5, the outer wall of the lower part of the fixed block 41 is movably sleeved with the inner cavity of the lower part of the grinding barrel 3, the outer wall of the middle part of the fixed block 41 is movably sleeved with an annular grinding block 43, the upper surface of the outer side of the annular grinding block 43 is fixedly connected with a grinding block 42, the inner wall of the grinding block 42 is movably sleeved with the outer wall of the upper part of the fixed block 41, the outer walls of the annular grinding block 43 and the grinding block 42 are movably sleeved with a grinding base 31, and the outer wall of the grinding base 31 is fixedly connected with the inner cavity of the upper part of the grinding barrel 3;
[0029] Through the action of the grinding block 42 and the grinding base 31, the polyurethane raw material is initially ground while moving downward. After the initial grinding, the polyurethane raw material continues to move downward to between the annular grinding block 43 and the inner wall of the lower part of the grinding base 31. Since the outer side of the annular grinding block 43 is arc-shaped, the polyurethane raw material can be further ground, so that the polyurethane raw material can be better ground, thereby improving the quality.
[0030] The grinding block 42 is conical in shape, the inner wall of the grinding base 31 matches the inner wall of the grinding block 42 and the annular grinding block 43, and the distance between the outer wall of the grinding block 42 and the annular grinding block 43 and the inner wall of the grinding base 31 decreases gradually;
[0031] Since the grinding block 42 is conical in shape, the contact time between the polyurethane raw material and the grinding block 42 and the grinding base 31 can be increased without affecting the continued downward movement, and since the distance between the outer wall of the grinding block 42 and the annular grinding block 43 and the inner wall of the grinding base 31 decreases, the polyurethane raw material can be gradually ground under rapid rotation, thereby increasing the grinding speed and improving the grinding quality.
[0032] A plurality of steel balls 49 are distributed in an annular array on the outer wall of the upper and lower parts of the grinding block 42 away from the grinding base 31, and the outer wall of the steel balls 49 is rotatably connected to the inner cavity of the upper part of the fixed block 41;
[0033] Through the action of the steel balls 49 , the grinding block 42 , driven by the annular grinding block 43 , can stably and rapidly rotate between the grinding base 31 and the fixed block 41 , thereby ensuring uniform grinding.
[0034] The inner cavities on the upper and lower sides of the annular grinding block 43 are slidably connected with annular sealing slide plates 410, and the opposite surfaces of the two annular sealing slide plates 410 are fixedly connected to the outer wall of the middle part of the fixed block 41 respectively;

[0038] The inner cavity in the middle of the fixed block 41 is fixedly connected with a motor 48, and the output end of the motor 48 is fixedly connected with a bevel gear 47. The lower surface of the outer wall of the bevel gear 47 is meshed with an annular bevel gear 46. The outer wall of the annular bevel gear 46 is movably sleeved with the inner cavity in the middle of the fixed block 41, and the lower surface of the annular bevel gear 46 is fixedly connected with the upper surface of the slide rail 1 44.
[0039] By starting the motor 48, the bevel gear 47 is rotated, thereby driving the annular bevel gear 46 to rotate. Through the action of the annular bevel gear 46, the slide rail 1 44 is rotated rapidly under the action of the slide rail 2 45, so that the annular grinding block 43 and the grinding block 42 are rotated rapidly under the action of the steel ball 49. Through the action of the annular grinding block 43, the grinding block 42 and the grinding base 31, the polyurethane raw material is ground.
[0040] The working principle of the utility model is as follows: when in use, the polyurethane raw material is poured into the inner cavity of the upper part of the grinding barrel 3, and then the motor 48 is started to rotate the bevel gear 47, thereby driving the annular bevel gear 46 to rotate, and the slide rail 1 44 is rapidly rotated under the action of the slide rail 2 45 through the action of the annular bevel gear 46, so that the annular grinding block 43 and the grinding block 42 are rapidly rotated under the action of the steel ball 49, and at this time, under the action of the upper part of the fixed block 41, the polyurethane raw material is slowly and evenly passed through the grinding channel between the grinding base 31 and the grinding block 42, and through the action of the grinding block 42 and the grinding base 31, the polyurethane raw material is initially ground when moving downward, and the polyurethane raw material after the initial grinding continues to move downward to between the annular grinding block 43 and the inner wall of the lower part of the grinding base 31, and because the outer side of the annular grinding block 43 is arc-shaped, the polyurethane raw material can be further ground, and the ground polyurethane raw material is discharged through the discharge pipe 2 at the bottom.
