Description

Technical Field

[0001] The invention relates to the technical field of color sorting optical limiting mechanisms, in particular to a color sorting optical limiting mechanism for a dry and wet dual-purpose color sorter. Background Art

[0002] A color sorter is a device that can automatically sort out different-colored particles in granular materials by using photoelectric detection technology based on the differences in the optical properties of the materials. That is, the color sorting optical structures such as the light source, photoelectric sensor, background plate and signal processing equipment are fixedly installed on the color sorter through a limiting mechanism, so that malignant impurities such as plastic, glass, metal, and same-color rods in grain can be sorted. Among them, the dry and wet dual-purpose color sorter is a type of color sorter, which means that it has the function of color sorting and screening dry and wet materials.

[0003] At present, the use effect of the existing color sorting optical limit mechanism is relatively simple. The single driving color sorting optical equipment is limited and fixed on the color sorter, so that the position of the light source and the photoelectric sensor is fixed, which is not convenient for adjusting the fixed position according to the size of the material. When facing larger or smaller materials, it is easy to have recognition obstruction and unclear recognition, which makes the recognition not sufficient and comprehensive, and the material is easy to gather during transportation. When the light source and the photoelectric sensor are limited and fixed, it is easy for some materials to touch the light source and the photoelectric sensor during the falling recognition process, thereby affecting the work of the light source and the photoelectric sensor. In addition, during the sorting and unloading process, the backlight panel at the bottom is prone to the phenomenon that the material adheres to and stays on its surface, so that the light reflection of the light source is blocked and affected, causing the brightness to be affected, thereby interfering with the color sorting work.

[0037] like Figure 3-Figure 6As shown, a pair of connection mechanisms 15 each include a pair of docking frames 1501, and the ends of the pair of docking frames 1501 that are far away from each other are in contact with the opposite sides of the screw rod movable sleeve seat 1403 and the sliding sleeve block 1406 respectively. The inner walls of the pair of docking frames 1501 are rotatably connected with a threaded rod 1502, and one end of the threaded rod 1502 is fixedly connected with a rotating round block 1503.

The outer walls of the two pairs of fixing bolts 1509 are threadedly connected with fixing nuts 15010, and the ends of the two pairs of fixing nuts 15010 that are close to each other are fixedly connected to the ends of the movable sleeve seat 1403 of the screw rod and the sliding sleeve block 1406 that are away from each other. By docking the first mounting hole 1507 and the second mounting hole 1508, in conjunction with the fixing bolt 1509 and the fixing nut 15010, the connecting block 1505 can be driven to be connected and fixed to the screw rod movable sleeve 1403 and the sliding sleeve block 1406 respectively, thereby driving multiple photoelectric sensor bodies 7 and a pair of lighting light sources 8 to be limited and fixed inside the connecting frame 5. In actual use, the first mounting hole 1507 and the second mounting hole 1508 are generally preset holes drilled in advance, and often a certain position deviation will occur during the docking process. At this time, rotating the threaded rod 1502 can drive the connecting block 1505 to move and adjust the position of the first mounting hole 1507, so as to drive the first mounting hole 1507 and the second mounting hole 1508 to be accurately docked, thereby ensuring the fixed installation of the connecting block 1505.

[0038] like Figure 1 , Figure 7 and Fig. 9As shown, the material dispersing mechanism 16 includes a pair of cams 1601, and the ends of the pair of cams 1601 that are close to each other are fixedly connected to the front output end of the dual-axis motor 403 and the rotating shaft on the rear end of the conveying roller 401 on the left side, respectively.

The materials on the conveyor belt 402 tend to gather together during the conveying process. A pair of cams 1601 rotate under the drive of the dual-axis motor 403. After the convex end of the cam 1601 is squeezed, the non-convex end contacts the T-shaped plate 1602. The pair of T-shaped plates 1602 drive the multiple dispersion plate frames 1608 to move to the left through the multiple L-shaped plates 1603 and the reciprocating sleeve block 1605, and scatter the materials along the top of the conveyor belt 402 to disperse the materials, reduce the aggregation of the materials, and avoid interference with subsequent color sorting.

[0039] like Fig. 9 As shown, the internal spacing of the plurality of dispersion plate racks 1608 decreases from left to right, and the end of the dispersion plate rack 1608 close to the support plate 2 is set in a triangular shape. By setting the end of the dispersion plate rack 1608 close to the support plate 2 in a triangular shape, the sharp end can be used to disperse the material, and the internal spacing of the plurality of dispersion plate racks 1608 decreases from left to right, the gathered material can be dispersed layer by layer, so that the material can be dispersed more fully and comprehensively.

[0040] like Figure 1 and Figure 7-Figure 8As shown, the lifting mechanism 17 includes a pair of pressing plates 1701 respectively fixedly connected to the opposite sides of a pair of T-shaped plates 1602, a pair of mounting frames 1 are respectively installed with a descending button 1702 and an ascending button 1703 at the ends away from each other, and two pairs of second electric telescopic rods 1606 located on the front and rear sides are respectively electrically connected to the pair of descending buttons 1702 and the ascending button 1703, a pair of reciprocating sleeves 1605 located in the middle position are fixedly connected to the top ends of the fixed rods 1704, and the outer walls of the fixed rods 1704 are fixedly connected to a pair of upper and lower limit blocks 1707, the outer walls of the pair of fixed rods 1704 are both sleeved with lifting sleeves 1705, and the outer walls of the pair of lifting sleeves 1705 and the bottom ends of the top plates 1607 are fixedly connected with connecting plates 1706. During the movement of the T-shaped plate 1602 and the multiple dispersion plate racks 1608 from right to left, a pair of pressing plates 1701 come into contact with the descending button 1702 on the right, so that the two pairs of second electric telescopic rods 1606 drive the top plate 1607 and the multiple dispersion plate racks 1608 to move downward and contact with the top of the conveyor belt 402, so as to facilitate the reverse forking and dispersing of the conveyed materials from left to right. During the movement of the T-shaped plate 1602 and the multiple dispersion plate racks 1608 from left to right, a pair of pressing plates 1701 come into contact with the ascending button 1703 on the left, and the two pairs of second electric telescopic rods 1606 drive the top plate 1607 and the multiple dispersion plate racks 1608 to move upward, away from the conveyor belt 402, to avoid interference with the transportation of materials.

[0041] like Figure 8 As shown, a pair of buffer pads 1708 are fixedly connected to the adjacent ends of the pair of limit blocks 1707, and the pair of buffer pads 1708 are sleeved on the outer wall of the fixed rod 1704, and the pair of buffer pads 1708 are respectively located at the top and bottom of the lifting sleeve 1705. Through the arrangement of the buffer pads 1708, when the lifting sleeve 1705 moves up and down and contacts with the pair of limit blocks 1707 respectively, it can play a buffering role and reduce the impact of the collision.

[0042] like Figure 1 and Fig. 9As shown, the descending collision mechanism 18 includes a baffle plate 1801 located at the top of the connecting frame 5, the right end of the connecting frame 5 is fixedly connected with an external plate 1802, and the external plate 1802 is connected to the baffle plate 1801 by screws, the top of the baffle plate 1801 is fixedly connected with a plurality of evenly distributed connecting bent rods 1803, and the left ends of the plurality of connecting bent rods 1803 are fixedly connected with collision balls 1804, and the bottom end of the top plate 1607 is in contact with the outer walls of the plurality of collision balls 1804. When the two pairs of second electric telescopic rods 1606 drive the top plate 1607 and the multiple dispersion plate racks 1608 to move downward, they will contact and collide with the multiple collision balls 1804, causing the top plate 1607 and the multiple dispersion plate racks 1608 to vibrate, so that when the multiple dispersion plate racks 1608 reversely disperse the gathered materials from right to left, the vibration effect is used to assist them, so as to quickly disperse the materials and enhance the use effect. Moreover, through the detachable screw connection, the baffle plate 1801 can be easily disassembled for easy use.

[0043] like Figure 1 and Fig.10 As shown, the collision shock mechanism 19 includes a pair of lower blocks 1901 respectively fixedly connected to the bottom ends of a pair of T-shaped plates 1602, the front and rear ends of the connecting frame 5 are fixedly connected with T-shaped rods 1902, and the outer walls of the pair of T-shaped rods 1902 are sleeved with translation sleeves 1903, the opposite sides of the lower blocks 1901 and the translation sleeves 1903 are fixedly connected with a pair of fixing plates, and a movable inclined rod 1905 is rotatably connected between the two pairs of fixing plates, the outer walls of the pair of T-shaped rods 1902 are sleeved with springs 1904, and the two ends of the springs 1904 are respectively fixedly connected to the opposite sides of the translation sleeves 1903 and the connecting frame 5, and the right ends of the pair of translation sleeves 1903 are fixedly connected with collision hammer rods 1906. Under the elastic restoring action of the spring 1904, when the T-shaped plate 1602 moves from right to left, the movable inclined rod 1905 pulls the translation sleeve 1903 toward the connecting frame 5, driving the collision hammer rod 1906 to contact and collide with the connecting frame 5, causing it to vibrate, so that the materials attached to a pair of inclined background plates 10 can fall off quickly, avoiding affecting the light reflection of the lighting source 8, ensuring the brightness in the color sorting working environment, avoiding interference with the color sorting work, and ensuring its working effect.

[0044] Working principle: First, operate the rotating round block 1503 to drive the threaded rod 1502 to rotate, so that it drives the threaded rod 1502 to rotate, and the connecting block 1505 moves left and right under the rotation of the threaded rod 1502, driving the first mounting hole 1507 to adjust its position so as to accurately dock with the second mounting hole 1508. After the first mounting hole 1507 and the second mounting hole 1508 are docked, the rotating fixing bolt 1509 passes through the first mounting hole 1507 and the second mounting hole 1508 in turn, and is locked and fixed with the fixing nut 15010. The bottom connecting block 1505 is respectively connected and fixed with the screw rod movable sleeve 1403 and the sliding sleeve block 1406, thereby driving multiple photoelectric sensor bodies 7 and a pair of lighting sources 8. The limit is fixed inside the connection frame 5, and then the rotating motor 1404 drives the bidirectional screw 1402 to rotate, so that a pair of screw movable sleeves 1403 move toward or away from each other, and drives the multiple photoelectric sensor bodies 7 and a pair of lighting sources 8 on both sides to move toward or away from each other with the assistance of the sliding sleeve block 1406 and the sliding rod 1405. The spacing between the multiple photoelectric sensor bodies 7 on both sides is adjusted to a suitable distance according to the size of the material. At the same time, the lighting source 8 is driven to adjust to a suitable height through a pair of first electric telescopic rods 9. Then the material passes through the receiving hopper 3 and falls onto the conveyor belt 402. The dual-axis motor 403 cooperates with a pair of conveying rollers 401 to drive the conveyor belt 402 to move, so that the conveyor belt 402 drives the material to the connection frame 5. The material is conveyed in the same direction as the conveyor belt 402, and the pair of cams 1601 rotates under the drive of the dual-axis motor 403 and the conveying roller 401. When the convex ends of the pair of cams 1601 squeeze the pair of T-shaped plates 1602, the T-shaped plates 1602 and the multiple dispersion plate racks 1608 move from left to right. At this time, the pair of pressing plates 1701 contact the rising button 1703 on the left, and the two pairs of second electric telescopic rods 1606 drive the top plate 1607 and the multiple dispersion plate racks 1608 to move upward stably with the assistance of the lifting sleeve block 1705 and the fixing rod 1704, away from the conveyor belt 402, to avoid interfering with the conveying of materials. The convex ends of the pair of cams 1601 are separated from the pair of T-shaped plates 1602, and switched to the non-convex ends and the pair of T-shaped plates 1602. When in contact, the elastic return action of the spring 1904 drives the T-shaped plate 1602 and the multiple dispersion plate racks 1608 to move from right to left. At this time, a pair of pressing plates 1701 contacts the descending button 1702 on the right, so that the two pairs of second electric telescopic rods 1606 drive the top plate 1607 and the multiple dispersion plate racks 1608 to move downward stably with the assistance of the lifting sleeve block 1705 and the fixing rod 1704, and contact with the top of the conveyor belt 402, so as to reversely disperse the gathered materials in the process from left to right, and in the process of the top plate 1607 and the multiple dispersion plate racks 1608 moving downward, they contact and collide with the multiple collision balls 1804, so that the top plate 1607 and the multiple dispersion plate racks 1608 vibrate.When the multiple dispersion plates 1608 reversely disperse the gathered materials from right to left, the vibration effect is used to assist them, so as to quickly disperse the materials, and this is repeated to disperse the gathered materials. Next, the dispersed materials are transported and orderly fall into the connection frame 5. The photoelectric sensor body 7 uses the illumination light source 8 to illuminate the materials, collects data on the materials at the viewpoint position, and identifies and judges the quality of the collected materials through the signal processing terminal 20. In the process of the left and right movement of the T-shaped plate 1602, the movable inclined rod 1905 pulls a pair of translation sleeves 1903 to move toward or away from each other, driving the collision hammer rod 1906 to repeatedly contact and collide with the connection frame 5 to generate vibration, so that the materials attached to the pair of inclined background plates 10 can fall off quickly, avoiding the influence of the light reflection of the illumination light source 8, ensuring the brightness in the color sorting working environment, avoiding interference with the color sorting work, and ensuring its working effect. Then, the good and bad materials are respectively discharged into the corresponding areas of the partition material separation box 13 by the injection of gas through the spray valve 12.
