[0020] like Figures 1-10 As shown, a raw material crushing device for tile production includes a frame 1 and a crusher 3 fixedly installed above the frame 1. The crusher 3 crushes the raw materials for tile production through its internal crushing rollers, and a row of magnetic bars 2 are arranged below the crusher 3. When the crushed powder falls through the outlet of the crusher 3, the magnetic bars 2 can absorb the metal particles in the powder. Figure 1-Figure 3 As shown, connecting rods 6 are provided on both sides of the frame 1, and the plurality of magnetic rods 2 are connected to the connecting rods 6 through connecting frames 7. In actual use, the plurality of magnetic rods 2 are divided into two groups, Figure 1 and Figure 2 As can be seen in the figure, one group of magnetic bars 2 is located below the outlet of the crusher 3, while the other group of magnetic bars 2 is located outside the crusher 3.

[0021] In order to drive the magnetic rod 2 to rotate and uniformly adsorb the metal particles, a first rack 12 is provided below the connecting rod 6. The first rack 12 and the connecting rod 6 are fixedly connected by a fixing rod, which is located at the end position of the first rack 12 and the connecting rod 6. Figure 2 As shown, a rotating shaft 9 is provided below the first rack 12, and a driving gear engaged with the first rack 12 is fixedly sleeved on the outer side of the rotating shaft 9. The engagement between the driving gear and the first rack 12 can drive multiple magnetic rods 2 to move back and forth. Furthermore, a circular shaft 201 is fixedly provided at both end faces of the magnetic rod 2, and a slider 16 that cooperates with the circular shaft 201 is clamped on the connecting frame 7. Figure 6 As shown, the circular shaft 201 passes through the slider 16 and rotates with it through the bearing, Figure 6 、 Figure 11 As shown, the circular shaft 201 passes through one end of the slider 16 and is fixedly sleeved with a driven gear 14. The driven gear 14 is located on the outside of the connecting rod 6 and can fit with the connecting rod 6. Figure 2 、 Figure 5 As shown, a second rack 15 meshing with the driven gear 14 is arranged below the frame 1. In actual use, when the connecting rod 6 drives the multiple magnetic bars 2 to move back and forth left and right, the engagement between the driven gear 14 and the second rack 15 can drive the magnetic bars 2 to rotate, which is conducive to uniformly adsorbing the metal particles on the outer surface of the magnetic bars 2.

[0022] In order to process the metal particles adsorbed on the magnetic rod 2, this solution provides a material frame 5 on the frame 1 and at both sides below the crusher 3. An adsorption unit 4 is installed in the material frame 5. The adsorption unit 4 can be an electromagnetic rod with stronger magnetic force than the magnetic rod 2. A resistance component that cooperates with the circular shaft 201 is provided on the outside of the material frame 5 and at the front and rear ends. In actual use, when more metal particles are adsorbed on the surface of the magnetic rod 2, the overall gravity of the magnetic rod 2 will increase, thereby causing the magnetic rod 2 and the slider 16 to move downward relative to the connecting frame 7, so that the circular shaft 201 can contact the resistance component during the horizontal movement, so that the slider 16 can move out of the connecting frame 7, and the magnetic rod 2 falls between the two resistance components and close to the adsorption unit 4 in the material frame 5, which is conducive to cleaning the metal particles on the magnetic rod 2.

[0023] like Figures 1-10 As shown, the blocking assembly includes a connecting plate 13 and a base 1302 provided on the side of the connecting plate 13 close to the material frame 5. The base 1302 is a U-shaped structure. A blocking rod 1301 is provided at one end of the top of the base 1302. The blocking rod 1301 can rotate relative to the base 1302 and the blocking rod 1301 and the base 1302 are elastically connected. When the blocking rod 1301 is not affected by external force, the blocking rod 1301 can be aligned with the base 1302. Figure 2-Figure 3 、 Figure 8 As shown, a cantilever 10 is fixedly mounted on the frame 1, and a guide block 19 is elastically connected to the cantilever 10, and the connecting plate 13 is fixedly connected to the guide block 19. Figure 9As shown, a card block 21 is elastically connected to the end face of one end of the base 1302 close to the baffle rod 1301, and a card slot that cooperates with the card block 21 is opened on the bottom end face of the baffle rod 1301. When the baffle rod 1301 is aligned with the base 1302, the card block 21 can be inserted into the card slot. A magnetic block 20 is slidably provided on the inner side surface of the base 1302, and a pull rope 22 is fixedly provided between the magnetic block 20 and the card block 21. The pull rope 22 passes through the base 1302 and slides with it. When the round shaft 201 abuts the baffle rod 1301 and falls to the base 1302, the pull rope 22 can be pulled by the attraction between the round shaft 201 and the magnetic block 20, thereby pulling one end of the card block 21 out of the slot. Of course, the round shaft 201 here is made of iron, so that there is magnetic attraction between the round shaft 201 and the magnetic block 20.

[0024] Reference Figure 6-Figure 7 As shown, an opening for the slider 16 to move out is provided on one side of the connecting frame 7, and a limit plate 18 is hinged at the opening, and the limit plate 18 is elastically matched with the connecting frame 7. The slider 16 is elastically connected to a limit block 1601 at the side away from the opening, and a limit groove 702 that cooperates with the limit block 1601 is provided on the inner wall of the connecting frame 7. The end of the limit block 1601 located inside the limit groove 702 is a spherical structure. When a large amount of metal particles are adsorbed on the surface of the magnetic rod 2, the limit block 1601 can be moved out of the limit groove 702, so that the slider 16 is aligned with the opening on the connecting frame 7.

[0025] In actual use, the engagement of the driving gear and the first rack 12 can drive multiple magnetic rods 2 to move back and forth left and right. When the material crushed by the crusher 3 falls, it will pass between two adjacent magnetic rods 2, and the magnetic rod 2 can adsorb the metal particles in the powder. The cooperation between the driven gear 14 and the second rack 15 can drive the magnetic rod 2 to rotate, so that the metal particles can be evenly adsorbed on the outer surface of the magnetic rod 2. When the surface of the magnetic rod 2 adsorbs more metal particles, the slider 16 can overcome the force between the limit block 1601 and the limit groove 702 and move downward, the slider 16 can be aligned with the opening of the connecting frame 7, and the circular shaft 201 on the magnetic rod 2 can be aligned with the blocking rod 1301 in the process of moving with the connecting rod 6. Contact, specifically, when the sunken magnetic rod 2 is moved out from the bottom of the crusher 3, the circular shaft 201 on the magnetic rod 2 can contact with the blocking rod 1301. Since the blocking rod 1301 is locked on the base 1302 through the cooperation of the card block 21 and the card slot, the blocking of the circular shaft 201 by the blocking rod 1301 allows the slider 16 connected to the circular shaft 201 to be guided out from the opening on the connecting frame 7, so that the magnetic rod 2 can fall along the blocking rod 1301. When the circular shaft 201 falls on the base 1302, the magnetic rod 2 stops moving downward, so that the magnetic rod 2 is in the material frame 5 and close to the electromagnetic rod. Since the magnetic force of the electromagnetic rod is greater than the magnetic force of the magnetic rod 2, the electromagnetic rod can adsorb the metal particles on the surface of the magnetic rod 2 to itself; When the round shaft 201 falls onto the base 1302, the suction force between the round shaft 201 and the magnetic block 20 can pull the pull rope 22, and the pull rope 22 can pull one end of the card block 21 out of the slot, so that the blocking rod 1301 can be unlocked from the base 1302 and be in a free rotation state. Therefore, when multiple magnetic rods 2 sink due to a large number of metal particles adsorbed on the surface, only the first magnetic rod 2 that passes through the blocking rod 1301 can fall onto the base 1302, and the remaining sinking magnetic rods 2 can only fall onto the base 1302 when they pass the blocking rod 1301 next time.

[0026] In summary, this device can introduce the sinking magnetic rod 2 into the material frame 5 through the provided resistance component, so that the metal particles adsorbed on the surface of the magnetic rod 2 are processed by the electromagnetic rod.

[0027] In addition, in actual use, a conveyor belt can be arranged below the frame 1, and the conveyor belt is arranged perpendicular to the frame 1, so that the material passing through the magnetic rod 2 can fall onto the conveyor belt.

[0028] like Figures 1-10As shown, in order to connect the connecting frame 7 with the connecting rod 6, this solution is fixed with a T-shaped slide 704 on one side of the connecting frame 7 close to the connecting rod 6 and at positions on both sides. The slide 704 passes through the connecting rod 6 and slides with it. The slide 704 is elastically connected to a protrusion 24 on the side away from the connecting frame 7. The top surface of one end of the protrusion 24 extending out of the slide 704 is provided with a slope 2401. A through groove is provided on the connecting rod 6 for the slide 704 to pass through, and a groove 601 that cooperates with the protrusion 24 is provided on the inner wall of the through groove. In the initial state, one end of the protrusion 24 with the slope 2401 is in the groove 601. Through this structure, the connecting frame 7 can be snapped into connection with the connecting rod 6.

[0029] A traction rope 23 is fixedly arranged between the top surface of the limit plate 18 and the protrusion 24. The traction rope 23 passes through the slide bar 704 and the connecting frame 7 and slides with the two. When the blocking rod 1301 blocks the movement of the circular shaft 201 so that the slider 16 is guided out of the opening, the limit plate 18 can be squeezed toward the horizontal direction by the slider 16, thereby tightening the traction rope 23, so that one end of the protrusion 24 moves out of the groove 601, so that the connecting frame 7 can move downward relative to the connecting rod 6.

[0030] Further, refer to Figures 6-11 As shown, the top of the connecting frame 7 and one side close to the connecting rod 6 extends outward to form a boss 703, and the outer side of the boss 703 is elastically connected to the pressure rod 25. Specifically, a circular hole is opened on the boss 703 to slide with the pressure rod 25. A first spring is fixed between the inner end surface of the circular hole and the pressure rod 25. Figures 1-6 、 Figure 10 As shown, a side plate 8 is provided on the top of the connecting rod 6, and the above-mentioned first rack 12 is fixedly connected to the side plate 8. The outer side surface of the boss 703 can contact the side of the side plate 8 close to the magnetic rod 2. The inner side surface of the side plate 8 and the position close to the middle protrude outward to form a protrusion 801, and both sides of the protrusion 801 are slopes 8011. The slope 8011 is located at the outer side of the crusher 3. When the magnetic rod 2 moves toward the direction close to the crusher 3, the pressure rod 25 can cooperate with the slope 8011, thereby driving the connecting frame 7 to move upward relative to the connecting rod 6. Specifically, combined with Figure 6 、 Figure 10 As shown, the top of the slope 8011 is set as an inclined extrusion surface 8012. When the pressure rod 25 moves to the top of the slope 8011, the pressure rod 25 can move out of the slope 8011 and be located on the inner side of the protrusion 801.

[0031] Reference Figure 6 As shown, a notch 701 is provided on one side of the connecting frame 7 and located above the limiting plate 18 , and the notch 701 is aligned with the slider 16 in the vertical plane; According to the above description, when the connecting rod 6 drives the magnetic rod 2 to move in the direction away from the crusher 3, the sinking suction rod can fall between the two bases 1302, and when the slider 16 is guided out from the opening on the connecting frame 7, it can drive the limit plate 18 to deflect in the horizontal direction, thereby pulling one end of the protrusion 24 out of the groove 601 through the traction rope 23, so that the connecting frames 7 at both ends of the sinking magnetic rod 2 can move downward relative to the connecting rod 6 until the boss 703 contacts the connecting rod 6, and when the connecting rod 6 drives the magnetic rod 2 to move in the direction close to the crusher 3, the fallen connecting frame 7 can move to the side of the magnetic rod 2 between the two bases 1302, so that the slider 16 on the circular shaft 201 can return to the connecting frame 7 from the slot 701, so that the connecting frame 7 can drive the magnetic rod 2 between the two bases 1302 to move synchronously. When the pressure rod 25 moves to the slope 8011, the pressure rod 25 can move upward along the slope 8011, thereby driving the connecting frame 7 to move upward synchronously. When the limit block 1601 on the slider 16 is aligned with the limit groove 702 on the connecting frame 7, the slider 16 can be re-engaged with the connecting frame 7. When the pressure rod 25 continues to move upward along the slope 8011 and finally moves out of the slope 8011 from the extrusion surface 8012, the connecting frame 7 can move upward to the initial position and be re-locked with the connecting rod 6 through the cooperation of the protrusion 24 and the groove 601. In the process of the connecting frame 7 moving upward, the inclined surface 2401 on the protrusion 24 can contact the connecting rod 6, so that the protrusion 24 can be compressed into the slide bar 704. When the protrusion 24 is aligned with the groove 601, the protrusion 24 can pop out and be inserted into the groove 601.

[0032] To sum up, this device cooperates with the protrusion 24 and the groove 601, so that when the magnetic bar 2 falls between the two bases 1302, the connecting frame 7 connected to the magnetic bar 2 will also move downward relative to the connecting rod 6, so that the notch 701 on the connecting frame 7 can be aligned with the slider 16. Subsequently, when the connecting rod 6 drives the magnetic bar 2 to approach the crusher 3, the slider 16 can re-enter the connecting frame 7, so that the magnetic bar 2 that falls between the two bases 1302 can return to its initial position.

[0033] Reference Figure 3-Figure 4 As shown, transmission teeth are provided at the top and bottom of the first rack 12. When the magnetic rod 2 falls between the two bases 1302, the driven gear 14 at the end of the magnetic rod 2 can engage with the first rack 12. Therefore, during the movement of the first rack 12, the magnetic rod 2 between the two bases 1302 can be driven to rotate, which is beneficial to the processing of metal particles on the surface of the magnetic rod 2.

[0034] like Figures 1-10As shown, the material frame 5 is fixed to the ground by a column. In actual use, the electromagnetic rod can be rotatably installed in the material frame 5.

Since it is a mature technical means in the mechanical field, the specific installation method of the electromagnetic rod and the method of driving the electromagnetic rod to rotate are not described in detail here.

[0035] There are rotatable suspension rods at both ends of the rotating shaft 9, and the suspension rods are fixedly connected to the frame 1. Specifically, a servo motor connected to the rotating shaft 9 is installed on the frame 1 to drive the rotating shaft 9 to rotate forward and reverse. The side panel 8 is fixedly connected to the frame 1 through an L-shaped support rod.
