[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Figures 1 to 5 As shown, this embodiment proposes a raw material grinding device for circulating resin preparation, including a device body 1, a feeding funnel 2 and a telescopic cylinder 5. The outer wall of the top of the device body 1 is installed with a feeding funnel 2, the inner wall of the device body 1 is symmetrically provided with an active cavity 4, and a grinding cavity 12 is provided below the feeding funnel 2. The inner wall of the active cavity 4 is symmetrically provided with a telescopic cylinder 5, and the output end of the telescopic cylinder 5 is connected with a pressing plate 6. The outer walls on both sides of the pressing plate 6 are symmetrically welded and have a push rod 7. A transmission shaft 8 is hingedly connected to one side of the push rod 7, and a grinding roller 9 is fixedly installed on the side of the transmission shaft 8 away from the push rod 7. The inner walls on both sides of the grinding cavity 12 are symmetrically provided with limiting grooves 13, and a discharge port 10 is provided below the grinding cavity 12. The outer wall on one side of the device body 1 is installed with a driving motor 3, and a discharge port 17 is provided on the side of the device body 1 away from the driving motor 3.

[0027] In this embodiment, the cross section of the limiting groove 13 is an annular movable groove, and the convex body provided at one end of the transmission shaft 8 matches the limiting groove 13 .

[0028] In this embodiment, the cross section of the feed opening 10 is trapezoidal, and the feed opening 10 is communicated with the grinding chamber 12 .

[0029] In this embodiment, tooth blocks are provided on the outer walls of the grinding rollers 9 , and there are intervals between the grinding rollers 9 .

[0030] Specific examples Figure 1 、 Figure 2 and Figure 4 As shown, when this structure is used, the raw materials prepared from the resin are transported to the top of the grinding roller 9 through the feed funnel 2, and the telescopic cylinder 5 is started. The telescopic cylinder 5 pushes and pulls the pressing plate 6 to drive the push rod 7 to move horizontally. Since the transmission shaft 8 is limited by the limiting groove 13, the transmission shaft 8 moves along the limiting groove 13 in a circular trajectory, and the propulsion groove 18 drives the grinding roller 9 to rotate. The large pieces of solid raw materials that fall are crushed and ground by the rotation of the grinding rollers 9 on both sides. The ground raw materials fall into the inside of the mixing drum 14 through the discharge port 10, and the rotating shaft 11 is driven to rotate by the driving motor 3. The blade 16 is driven by the rotating shaft 11 to hinge and perform secondary cutting and crushing on the raw materials. This structure can improve the raw material grinding efficiency and fully crush and grind the raw materials at the same time.

[0031] Example 2: A propulsion groove 18 is provided below the discharge port 10 , and the driving shaft of the driving motor 3 passes through the inner wall of the device body 1 and is connected to the rotating shaft 11 .

[0032] In this embodiment, the propulsion groove 18 is conical, and one end of the propulsion groove 18 away from the driving motor 3 is communicated with the discharge port 17 .

[0033] In this embodiment, the rotating shaft 11 is located at the center of the propulsion groove 18 , and a thread 15 is installed on the outer wall of the rotating shaft 11 , and the thread 15 fits the inner wall of the propulsion groove 18 .

[0034] In this embodiment, the propulsion groove 18 is located just below the grinding chamber 12 , and a mixing drum 14 is installed thereon. Blades 16 are evenly spaced at the front end of the rotating shaft 11 .

[0035] Specific examples Figure 1 、 Figure 3 and Figure 5 As shown, when this structure is used, after the resin raw material is ground, the drive motor 3 is started and the shaft 11 is driven by the drive motor 3 to rotate, and the shaft 11 is used to drive the thread 15 to rotate. Since the propulsion groove 18 is a tapered structure and the thread 15 fits the inner wall of the propulsion groove 18, the thread 15 is rotated along the trajectory of the propulsion groove 18 to push the raw material from one end to the other end, and then discharged through the discharge port 17 for unified collection. This structure is simple to operate and convenient for collecting and processing pigments after grinding.

[0036] Working principle: When grinding the resin raw material, the raw material is placed into the interior of the device body 1 through the feed funnel 2, so that the raw material falls above the grinding roller 9, and the telescopic cylinder 5 is started. The push rod 7 is pressed by the telescopic cylinder 5 and pushed by the pressing plate 6 to drive the transmission shaft 8 to move. Due to the limiting effect of the limiting groove 13 of the transmission shaft 8, one end of the transmission shaft 8 moves in a circular trajectory with the center position of the grinding roller 9 as the axis, and the other end of the transmission shaft 8 drives the grinding roller 9 to rotate, grinding and crushing the raw material in the middle, and the crushed raw material falls into the mixing drum 14 through the discharge port 10. The drive motor 3 is started and driven by the drive motor 3 to rotate. The rotating shaft 11 drives the thread 15 and the blade 16 to rotate, and the raw material is cut and crushed by the blade 16. After the raw material is thoroughly ground and crushed, the raw material is pushed by the thread 15 to move along the trajectory of the propulsion groove 18, and then the ground raw material is discharged from the discharge port 17 for unified collection. This structure can improve the grinding and crushing efficiency and uniformly transport and collect the ground raw materials.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
