[0027] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0028] Embodiment 1:

[0029] This embodiment introduces the specific structure of a feeding mechanism for ceramic powder production with a crushing structure. Specifically, refer to Figures 1 - 5 as shown, it includes a crushing roller 1 and an adjusting crushing cylinder 3 (horizontally arranged on one side of the crushing roller 1, and the axes of the two are parallel). Both ends of the crushing roller 1 are processed with driving roller shafts 7. A driven roller shaft 5 is arranged inside the adjusting crushing cylinder 3. The driven roller shaft 5 includes a transmission shaft column 501. Both ends of the transmission shaft column 501 are provided with linkage shaft columns 503. One end of each of the two linkage shaft columns 503 is provided with a driving shaft column 502. The surface of the linkage shaft column 503 is processed with a reciprocating spiral groove 11;

[0030] AsFigure 3 and Figure 4 As shown in Figure 4 , a controlled seat 12 is slidably connected inside the reciprocating spiral groove 11. A sliding seat 13 is provided at the bottom of the controlled seat 12. Connecting rods 14 are machined at the bottoms of both ends of the sliding seat 13, and sliding rods 15 are provided inside both ends of the sliding seat 13;

[0031] Among them, one end of each of the two connecting rods 14 at the bottom of one sliding seat 13 is fixedly machined with the inner wall of the adjusting crushing cylinder 3. By controlling the rotation of the linkage shaft column 503 and with the cooperation of the reciprocating spiral groove 11 and the controlled seat 12, the linkage shaft column 503 can control the sliding seat 13 to reciprocate outside the two sliding rods 15. Since the driven roller shaft 5 and the adjusting crushing cylinder 3 are coaxially arranged, the sliding seat 13 can be used to control the two connecting rods 14 to drive the adjusting crushing cylinder 3 to reciprocate outside the driven roller shaft 5, facilitating the cooperation between the crushing roller 1 and the adjusting crushing cylinder 3 (during the rotation of the crushing roller 1, due to the characteristic that the adjusting crushing cylinder 3 is fixedly installed by the two sliding rods 15, it can only move). The ceramic is roll-pressed and crushed, and at the same time, the adjusting crushing cylinder 3 reciprocates along the axial direction on one side of the crushing roller 1 to friction-crush the ceramic, so as to avoid incomplete crushing of local ceramics;

[0032] Secondly, in order to facilitate the rotation of the crushing roller 1, the rotation of the driven roller shaft 5 can be synchronously controlled to drive the adjusting crushing cylinder 3 to reciprocate along its axial direction. As shown in Figure 1 , Figure 3 and Figure 5 , a controlled gear 8 is assembled and connected to the middle of one driving roller shaft 7. Driving belt wheels 16 are assembled and connected to the outside of one end of one driving roller shaft 7 and the outside of one end of a transmission shaft column 501. A plurality of transmission belts 6 are connected in a transmission manner between the outside of the two driving belt wheels 16. By connecting the controlled gear 8 to the motor using a gear, when the motor works, with the cooperation of the gear and the controlled gear 8, the driving roller shaft 7 is driven to rotate, so that the two driving belt wheels 16 rotate synchronously under the drive of the plurality of transmission belts 6 (one driving belt wheel 16 is fixed to the outside of one driving roller shaft 7, and the other driving belt wheel 16 is fixed to the outside of the driven roller shaft 5), thereby providing power for the rotation of the driven roller shaft 5; Figure 1 、 Figure 3 and Figure 5 Furthermore, in order to facilitate the connection and fixation of the transmission shaft column 501, the linkage shaft column 503 and the drive shaft column 502. As shown in Figure 4 and Figure 5 ,

[0033] As shown in Figure 4 and Figure 5 , Figure 4 and Figure 5As shown, connection sleeves 10 are integrally formed on both ends of the drive shaft column 501 and the outside of one end of the drive shaft column 502. Connection shafts 17 are integrally formed on both ends of the linkage shaft column 503. By inserting the connection shafts 17 into the inside of the connection sleeves 10, after pinning pins inside the connection shafts 17 and the connection sleeves 10, one end of the linkage shaft column 503 can be fixed to one end of the drive shaft column 502, and the other end of the linkage shaft column 503 can be fixed to the drive shaft column 501, realizing the overall assembly work of the driven roller shaft 5.

[0034] By adopting the above technical solution:

[0035] In the above design, a motor with a gear on the rotating shaft is used to control the rotation of the controlled gear 8. With the help of the controlled gear 8, the driving roller shaft 7 is controlled to drive the crushing roller 1 to rotate, so that the driving roller shaft 7 connected by two driving pulleys 16 and multiple transmission belts 6 drives the driven roller shaft 5 to rotate. Since the driven roller shaft 5 is composed of a drive shaft column 501, two linkage shaft columns 503, and two drive shaft columns 502, a controlled seat 12 is arranged inside the reciprocating spiral groove 11 machined on the surface of the linkage shaft column 503. When the driven roller shaft 5 is in a rotating state, the controlled seat 12 reciprocates along the axis direction of the linkage shaft column 503 inside the reciprocating spiral groove 11 (the controlled seat 12 slides outside the two slide bars 15 through the slide seat 13 and maintains a moving state), thereby driving the adjusting crushing cylinder 3 at one end of the two connecting rods 14 on the surface of the slide seat 13 to reciprocate along the axis direction. In this state, the crushing roller 1 rolls and cooperates with the adjusting crushing cylinder 3 to roll and crush the ceramic, and the adjusting crushing cylinder 3 moves and frictions to crush the ceramic, which is beneficial to improving the powder grinding coverage rate of the ceramic, avoiding incomplete powder grinding, and there is no need to screen the ceramic powder that does not reach the final fineness, thus achieving the effect of cost saving.

[0036] Embodiment 2:

[0037] Based on Embodiment 1, this embodiment introduces the specific structures of the crushing roller 1 and the adjusting crushing cylinder 3, as Figure 1 and Figure 2 shown, the same feed frame 4 is arranged outside the crushing roller 1 and the adjusting crushing cylinder 3;

[0038] Among them, by passing both ends of the two slide bars 15 on one slide seat 13 through the inside of the feed frame 4 and respectively screwing nuts at both ends of the slide bars 15, the slide bars 15 can be fixed to the feed frame 4, the slide seat 13 is erected outside the two slide bars 15, and in the form of the fixed setting of the slide bars 15, the controlled seat 12 is supported to be controlled by the rotating linkage shaft column 503 (based on the cooperation of the reciprocating spiral groove 11 and the controlled seat 12), driving the slide seat 13 to reciprocate outside the two slide bars 15;

[0039] Secondly, in order to avoid being blocked by the inner walls at both ends of the feeding frame 4 during the process of adjusting the reciprocating movement of the crushing cylinder 3 along its axial direction, as Figure 2 shown, movable annular grooves 9 are machined at the inner walls at both ends of the feeding frame 4. The length of the adjusting crushing cylinder 3 is longer than that of the crushing roller 1. By enabling the adjusting crushing cylinder 3 to reciprocate along the axis, its two ends are respectively movably connected to the interiors of the two movable annular grooves 9, which can ensure that there is sufficient movable space during the process of the adjusting crushing cylinder 3 cooperating with the crushing roller 1 to crush ceramics;

[0040] Furthermore, in order to enable the ceramic material to be ground to accurately fall between the crushing roller 1 and the adjusting crushing cylinder 3 for grinding, as Figure 1 shown, a cover plate 2 is assembled and connected to the inner side of the top of the feeding frame 4. By enabling the cover plate 2 to cover the tops of the crushing roller 1 and the adjusting crushing cylinder 3 and exposing the surface of the contact area between the crushing roller 1 and the adjusting crushing cylinder 3, the tops on both sides of the cover plate 2 are machined into inclined surfaces, which can guide the raw materials to the center and fall between the two crushing rollers 1 when the raw materials fall on the top of the cover plate 2.

[0041] By adopting the above technical solutions:

[0042] The above design assembles the cover plate 2 on the inner side of the top of the feeding frame 4, and the tops on both sides of the cover plate 2 are machined into inclined surfaces and are in a state of covering the tops of the crushing roller 1 and the adjusting crushing cylinder 3. When materials are put into the inner side of the top of the feeding frame 4, with the guidance of the inclined surfaces, the materials gather towards the center and fall between the crushing roller 1 and the adjusting crushing cylinder 3, and thus are ground into powder by the crushing roller 1 and the adjusting crushing cylinder 3, which is beneficial to avoiding the materials from falling into the bottom through the gaps between the inner wall of the feeding frame 4 and the crushing roller 1 and the adjusting crushing cylinder 3, affecting the grinding effect.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
