Description

Technical Field

[0001] This invention relates to the field of intelligent sorting technology, and in particular to a vibrating feed hopper for an electromagnetic vibrator in a color sorter. Background Technology

[0002] Color sorters are devices that automatically separate materials based on differences in color, shape, texture, and other characteristics using photoelectric detection technology. They are widely used in agricultural and industrial products. The vibrating feeder is a key component of the color sorter, which uniformly, regularly, and continuously transports lumpy or granular materials from the hopper or bin to the receiving device, facilitating material identification and sorting.

[0003] In related technologies, the bucket of electromagnetic vibrator is mostly made of stainless steel plates spliced ​​and welded together, which has a complex processing technology and poor processing consistency;

[0004] The current process for the feeding hopper of electromagnetic vibrators mainly involves the cutting, bending, welding, grinding, and surface treatment of stainless steel. The bending process can introduce dimensional tolerances, the welding method can cause deformation of the hopper, and the welding skills of the personnel can make it difficult to ensure consistency in the size and position of the weld. Moreover, the welding process can produce weld scars and weld marks on the inner and outer surfaces of the hopper, resulting in differences among multiple vibrating hoppers on the same equipment, which will ultimately affect the inconsistency of the vibrator's working frequency and amplitude.

[0005] Multiple electromagnetic vibrating feeders typically operate in parallel on a single color sorter, using the same set frequency and duty cycle. This can lead to inconsistencies in the feed rates between them. Overfeeding causes the material to be conveyed to the chute or material identification zone before it is fully dispersed, affecting the sorting effect. Underfeeding reduces production capacity and impacts the color sorter's efficiency. Summary of the Invention

[0006] To address the technical problems mentioned above, the present invention provides a vibrating feed hopper for an electromagnetic vibrator in a color sorter.

The locking component can lock and fix the first column, the anti-loosening component can maintain the locked state of the first column, and the unlocking component can release the locking state of the anti-loosening component on the first column.

[0012] As a further improvement to the above solution, the second connecting plate is provided with a first slot through which the first column can be axially inserted.

[0013] As a further improvement to the above solution, the locking assembly includes a second column rotatably inserted into the first connecting plate. One end of the second column has a second slot into which the first column can be inserted. The second slot has a spiral-shaped limiting groove axially formed in its groove wall. A limiting block is provided on the outer peripheral side wall of the first column, which slides and engages with the limiting groove. The limiting groove has an entrance near the opening of the second slot, allowing the limiting block to enter the limiting groove. A first locking rod is concentrically provided at one end of the first column. A first locking groove is formed in the second slot, which threadedly engages with the first locking rod.

[0014] As a further improvement to the above solution, the anti-loosening component includes a ratchet that is sleeved and fixed to the outer periphery of the second column, and the first connecting plate is provided with a pawl that cooperates with the ratchet.

[0015] As a further improvement to the above solution, the end of the pawl away from the adjacent ratchet extends to form a pressure-bearing section, and a fixing plate is provided on the first connecting plate.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] Example 1

[0035] Please combine Figures 1 to 9 The vibrating feed hopper of the color sorter electromagnetic vibrator includes a hopper 1 with an open end and an internal chute (not marked), a base 2 located below the hopper 1, and a vibrating device. After the material falls into the chute of the hopper 1, it will be completely dispersed by vibration and can be conveyed through the opening to the corresponding chute of the material identification area for subsequent sorting operations.

[0036] Two first connecting plates 8 are inclinedly arranged at the bottom of the bucket body 1. Each first connecting plate 8 is elastically supported on the base 2 by a spring 32. A vibration device is set on the base 2, which can drive the bucket body 1 to vibrate continuously. The bottom of the base 2 is connected to a base plate (not shown) by a vibration isolation spring 6.

[0037] The bottom of the bucket body 1 has reinforcing ribs 7 perpendicular to the first connecting plate 8. The bucket body 1, reinforcing ribs 7, and the first connecting plate 8 are integrally die-cast, which simplifies the manufacturing of the bucket body 1, reduces production costs, and ensures consistency across multiple production batches. The die-cast bucket body 1 is easy to surface treat, achieving a very smooth surface roughness. In this embodiment, the bucket body 1 can be made of aluminum, which effectively reduces its own weight and energy loss during vibration compared to traditional steel structures.

[0038] The vibration device includes an electromagnetic coil 4 and an armature 5 that are electromagnetically attracted to each other. The armature 5 is installed on a first connecting plate 8 located on the side away from the opening of the hopper 1, and the electromagnetic coil 4 is installed on the base 2.

[0039] In this embodiment, by using a die-cast bucket body 1, the connection method between the bucket body 1 and the armature 5 can be changed, eliminating the intermediate adapter and screw connection, reducing the risk of fatigue damage to the connectors and screws, enhancing the stability of vibration transmission, and effectively strengthening the structural strength of the bucket body 1 itself. Compared with the previous bending and welding structure, it reduces the risk of fatigue cracking of the bucket body 1.

[0040] In order to improve the stability of the connection between the spring 32 and the bucket 1 and the ease of disassembly and assembly, and to prevent the spring 32 from separating from the first connecting plate 8 when the bucket 1 is vibrating, in this embodiment the spring 32 is fixed to the base 2 on the bottom side and a rigid second connecting plate 3 is integrally provided on the top side. The second connecting plate 3 and the corresponding first connecting plate 8 are detachably connected by a locking device.

[0041] Specifically, the locking device includes a first column 10, a locking component, an anti-loosening component, and an unlocking component. The first column 10 is disposed on the second connecting plate 3, and the locking component, anti-loosening component, and unlocking component are all disposed on the first connecting plate 8. The locking component can lock and fix the first column 10, the anti-loosening component can maintain the locked state of the first column 10, and the unlocking component can release the locking state of the anti-loosening component on the first column 10.

[0042] A first pressing plate 17 is provided at one end of the first column 10 to complete the pressing operation of the first column 10.

[0043] The second connecting plate 3 has a first slot 9 for the first column 10 to pass through axially. The first slot 9 has a docking groove 31 on the side facing the groove of the first connecting plate 8 for the second column 11 to be inserted into, and the second column 11 can rotate relative to the first column 10 in the docking groove 31.

[0044] The locking assembly includes a second column 11 rotatably inserted into the first connecting plate 8. One end of the second column 11 has a second slot 12 into which the first column 10 can be inserted. The second slot 12 has a spiral-shaped limiting groove 14 axially formed in the groove wall. The outer peripheral side wall of the first column 10 is provided with a limiting block 13 that slides and engages with the limiting groove 14. The limiting groove 14 has an entrance near the opening of the second slot 12 for the limiting block 13 to enter the limiting groove 14. A first locking rod 15 is concentrically provided at one end of the first column 10. A first locking groove 16 is formed in the second slot 12 that is threadedly engaged with the first locking rod 15.

[0045] The anti-loosening component includes a ratchet 18 sleeved and fixed to the outer periphery of the second column 11, and a pawl 19 that engages with the ratchet 18 is provided on the first connecting plate 8. The pawl 19 is inserted into the plate body of the first connecting plate 8 via a coil spring and a spool. When the coil spring is in a non-deformed state, the pawl 19 is in contact with the ratchet 18. In this embodiment, the ratchet 18 and pawl 19 are configured to allow the second column 11 to rotate only when the first column 10 is inserted into the second slot 12.

[0046] The end of the pawl 19 away from the adjacent ratchet 18 extends to form a pressure-bearing section (not shown). A fixing plate 20 is provided on the first connecting plate 8. A pressure rod 21 that is elastically inserted into the fixing plate 20 and engages with the pressure-bearing contact and compression is provided.

[0047] A second pressing plate 22 is provided at the top of the pressing rod 21, and a return spring 23 is sleeved on the outside of the pressing rod 21. The two ends of the return spring 23 are respectively connected to the second pressing plate 22 and the fixing plate 20.

[0048] The assembly steps of the second connecting plate 3 and the first connecting plate 8 on the reed 32 in this embodiment are as follows:

[0049] S1. Bring the spring 32 and the second connecting plate 3 together close to the first connecting plate 8, so that one end of the second column 11 enters the docking groove 31, and completes the pre-positioning between the second connecting plate 3 and the first connecting plate 8 on the spring 32.

[0050] S2. The first column 10, together with the first locking rod 15, is inserted into the second slot 12 through the first slot 9. This causes the limiting block 13 to enter the limiting groove 14 through the inlet. As the first column 10 moves axially, it rubs and compresses the spiral-shaped limiting groove 14, forcing the second column 11 to rotate unidirectionally. When the first locking rod 15 moves to the first locking groove 16, it engages with the first locking groove 16 through its own axial movement and the rotation of the second column 11, thus achieving a threaded lock-on connection between the second mating plate 3 on the spring 32 and the first connecting plate 8. The presence of the ratchet 18 and pawl 19 ensures that the second connecting plate 3 and the first connecting plate 8 remain locked in place.

[0051] The disassembly steps for the second connecting plate 3 on the reed 32 and the first connecting plate 8 in this embodiment are as follows:

[0052] The pressure bar 21 is pressed down by the second pressing plate 22 to squeeze the pressure section, forcing the pawl 19 to deflect away from the ratchet 18. At this time, the second column 11 can rotate in the opposite direction and be pulled outward from the first column 10, that is, the locking state between the second connecting plate 3 and the first connecting plate 8 on the spring 32 is released.

[0053] Example 2

[0054] Please combine Figures 1 to 10 This embodiment is an improvement on embodiment 1. To further improve the connection stability between the second connecting plate 3 and the first connecting plate 8 on the spring 32, a roller 24 is installed in the second connecting plate 3. Part of the roller 24 extends into the docking groove 31 and can contact the outer peripheral side wall of the second column 11 extending into the docking groove 31. A rotating shaft 25 is concentrically fixed on the roller 24. A worm gear 26 is fixed at one end of the rotating shaft 25. A worm 27 that cooperates with the worm gear 26 is rotatably arranged in the second connecting plate 3. A cylinder 28 is fixed at the centripetal end of the worm 27. A second locking rod 29 is threaded into the centripetal end of the cylinder 28. A limit plate (not shown) is provided in the second connecting plate 3. A through hole (not shown) is opened on the limit plate. A limit sleeve (not shown) that can move along the axial direction of the through hole is slidably engaged in the limit hole. The limit sleeve is sleeved and fixed on the outer peripheral side wall of the second locking rod 29. A second locking groove 30 is provided on the outer periphery of the first column 10 to engage with the second locking rod 29.

[0055] The working principle of this embodiment is as follows:

[0056] When the second column 11 extends into the mating groove 31 and rotates within it, it drives the roller 24, the rotating shaft 25, and the worm gear 26 to rotate. The worm gear 26 drives the worm 27 and the cylinder 28 to rotate, causing the cylinder 28 and the second locking rod 29 to engage with each other through the threads. Under the combined limiting action of the through hole of the limiting plate and the limiting sleeve, the second locking rod 29 is forced to extend axially from the cylinder 28 to be inserted into the second locking groove 30, thus further fixing the first column 10 and further improving the connection stability between the second connecting plate 3 and the first connecting plate 8 on the spring 32.

[0057] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
