Description

Technical Field

[0001] The utility model belongs to the technical field of color sorter feed hoppers, in particular to an anti-blocking mechanism for a color sorter feed hopper. Background Art

[0002] A color sorter uses photoelectric detection technology to automatically separate dissimilar particles from granular materials based on differences in their optical properties. It is a non-destructive sorting device used for quality inspection and grading of bulk materials. It is widely used in the grain, food, pigment, and chemical industries. It is highly effective in separating challenging impurities and specialty materials such as recycled plastic flakes, plastic granules, corn, various beans, various types of rice, minerals, chili peppers, Sichuan peppercorns, garlic, melon seeds, raisins, seeds, traditional Chinese medicine, dried shrimp, dried small shrimp, anchovies, glass, metal, and homochromic rods.

[0003] During the process of color sorting, a feed hopper is often needed to put the materials into the color sorter so that the color sorter can perform color sorting.

[0004] At present, the feed hopper of the color sorter in the existing technology is usually a hollow feed shell. When color sorting grain materials such as rice and corn, since the materials are continuously fed into the feed hopper, when too much material is fed, the material particles are squeezed against each other and easily piled up in the feed hopper, causing blockage. In addition, there is no auxiliary mechanism inside the feed hopper to break up and guide the accumulated materials, making it impossible to continuously and stably transport the materials into the color sorter, affecting the color sorting progress of the materials and the use effect of the color sorter.

[0005] In response to the above problems, we propose an anti-blocking mechanism for the feed hopper of a color sorter. Utility Model Content

Two rotating rods are arranged inside the feed hopper body for relative rotation, and a cam is provided on the rotating rod, which cooperates with the vibrating plate. The rear end of the rotating rod passes through the rear surface of the feed hopper body, and the left and right parts of the rotating rods located outside the feed hopper body are respectively provided with a driving gear and a driven gear, and the driving gear is meshed with the driven gear. A vibrating mechanism is provided on the lower side of the inside of the feed hopper body, and a knocking mechanism is provided on the left and right sides of the outside of the feed hopper body. A transmission assembly is provided between the rear end of the rotating rod and the knocking mechanism.

[0008] The vibrating mechanism includes a first vibrating rod, a movable groove, a guide rod, a cross rod, a longitudinal rod, a second vibrating rod and a second spring. Several of the first vibrating rods are relatively fixed on the side of the two vibration plates away from the first spring. The two movable grooves are relatively opened on the left and right sides of the inner wall of the feed hopper body. The guide rod is fixed inside the movable groove. The cross rod is movably mounted on the guide rod. The ends of the two cross rods close to each other are fixedly connected to the longitudinal rod. Several of the second vibrating rods are fixed on the upward side of the longitudinal rod.

[0009] The cross bar is arranged directly below the cam, and the cam and the cross bar cooperate with each other. The second spring is sleeved on the outside of the guide rod, and the two ends of the second spring are respectively connected to the cross bar and the bottom of the inner wall of the movable groove. The bottom of the movable groove is an inclined structure.

[0010] The knocking mechanism includes a support shaft, a disc, a movable plate, a third spring, a piston rod and a hammer head. The two support shafts are respectively arranged on the left and right sides of the feed hopper body. The disc is arranged on the support shaft. A movable cavity is opened on one side of the inner part of the disc. The movable plate is movably arranged inside the movable cavity. The piston rod and the disc are slidably matched, and the inner end of the piston rod extends into the movable cavity and is fixedly connected to the movable plate.

The support shaft rotates with the fixed plate. The two pulleys are respectively arranged on the rotating rod and the support shaft. The transmission belt is arranged between the two pulleys.

[0012] Two limit rods are relatively fixed inside the movable cavity, and the limit rods pass through the movable plate. The movable plate slides with the limit rods. A servo motor is installed on the rear surface of the feed hopper body through a mounting frame, and the output end of the servo motor is connected to the rear end of the rotating rod on the left.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model facilitates the synchronous and opposite rotation of the two rotating rods through the meshing action of the driving gear and the driven gear, thereby driving the cam to rotate. When the raised portion of the cam approaches the vibrating plate, the movable end of the vibrating plate is lifted upward under the hinged action of the vibrating plate and the inner wall of the feed hopper body. When the raised portion of the cam moves away from the vibrating plate, the vibrating plate is pulled back to its initial position in combination with the elastic action of the first spring, thereby achieving the effect of beating and vibrating the material put into the feed hopper body.

[0015] The vibrating mechanism is used to vibrate the material inside the feed hopper body to achieve the effect of breaking up the material, avoiding mutual squeezing between material particles, causing the material particles to be stacked together and accumulated in the feed hopper, causing blockage. At the same time, under the action of the knocking mechanism, the outer wall of the feed hopper body is knocked to avoid the material from adhering to the inner wall of the feed hopper body, ensuring the material discharge effect, and solving the problem that the existing color sorter feed hopper does not have any auxiliary mechanism inside, which breaks up and guides the accumulated materials, making it impossible to continuously and stably transport the materials to the inside of the color sorter, affecting the color sorting progress of the materials and the use effect of the color sorter.

[0024] This specific embodiment is a color sorter feed hopper anti-blocking mechanism, such as Figure 1-Figure 7As shown, the anti-blocking mechanism for the feed hopper of the color sorter includes a feed hopper body 1, two vibration plates 2 are relatively hinged on the inner wall of the feed hopper body 1, and a plurality of first springs 3 are connected between the sides of the two vibration plates 2 that are away from each other and the inner wall of the feed hopper body 1. Two rotating rods 4 are arranged inside the feed hopper body 1 for relative rotation, and a cam 5 is provided on the rotating rod 4 to cooperate with the vibration plate 2. The rear end of the rotating rod 4 passes through the rear surface of the feed hopper body 1, and the left and right rotating rods 4 are located on the outside of the feed hopper body 1. The parts are respectively provided with a driving gear 6 and a driven gear 7, and the driving gear 6 is meshed with the driven gear 7. A vibration mechanism is provided on the lower side of the inside of the feed hopper body 1, and a knocking mechanism is provided on the left and right sides of the outside of the feed hopper body 1. A transmission assembly 22 is provided between the rear end of the rotating rod 4 and the knocking mechanism.

[0025] Through the meshing action of the driving gear 6 and the driven gear 7, it is easy to drive the two rotating rods 4 to rotate synchronously in opposite directions, thereby driving the cam 5 to rotate. When the raised portion of the cam 5 is close to the vibration plate 2, the movable end of the vibration plate 2 is lifted upward under the hinged action of the vibration plate 2 and the inner wall of the feed hopper body 1. When the raised portion of the cam 5 is away from the vibration plate 2, combined with the elastic action of the first spring 3, the vibration plate 2 is pulled back to its initial position, achieving the effect of slapping and vibrating the material put into the feed hopper body 1, ensuring the stable discharge of the material inside the feed hopper body 1, and avoiding the material from being blocked inside the feed hopper body 1.

[0026] The vibration mechanism includes a first vibrating rod 8, a movable groove 9, a guide rod 10, a cross bar 11, a longitudinal rod 12, a second vibrating rod 13 and a second spring 14. Several first vibrating rods 8 are relatively fixed on the side of the two vibration plates 2 away from the first spring 3. The two movable grooves 9 are relatively opened on the left and right sides of the inner wall of the feed hopper body 1. The guide rod 10 is fixed inside the movable groove 9. The cross bar 11 is movably sleeved on the guide rod 10. The ends of the two cross bars 11 close to each other are fixedly connected to the longitudinal rod 12. Several second vibrating rods 13 are fixed on the upward side of the longitudinal rod 12. The cross bar 11 is arranged directly below the cam 5. The cam 5 and the cross bar 11 cooperate with each other. The second spring 14 is sleeved on the outside of the guide rod 10, and the two ends of the second spring 14 are respectively connected to the cross bar 11 and the bottom of the inner wall of the movable groove 9. The bottom of the movable groove 9 is an inclined structure.

[0027] Through the reciprocating vibration of the vibration plate 2, the first vibrating rod 8 is driven to move synchronously to vibrate the material inside the feed hopper body 1. At the same time, the mutual cooperation between the cam 5 and the cross bar 11, combined with the sliding cooperation between the cross bar 11 and the guide rod 10, and the elastic action of the second spring 14, it is convenient to drive the longitudinal rod 12 to move up and down, and then drive the second vibrating rod 13 to move up and down, further vibrating the material inside the feed hopper body 1, ensuring the material discharge effect, avoiding mutual squeezing between material particles, and easily causing the material particles to be stacked together and accumulated in the feed hopper, causing blockage.

[0028] The knocking mechanism includes a support shaft 15, a disc 16, a movable plate 18, a third spring 19, a piston rod 20 and a hammer head 21. The two support shafts 15 are respectively arranged on the left and right sides of the feed hopper body 1, and the disc 16 is arranged on the support shaft 15. A movable cavity 17 is opened on one side of the inner part of the disc 16. The movable plate 18 is movably arranged inside the movable cavity 17. The piston rod 20 slides with the disc 16, and the inner end of the piston rod 20 extends into the movable cavity 17 and is fixedly connected to the movable plate 18. Several third springs 19 are connected between the side of the movable plate 18 away from the piston rod 20 and the inner wall of the movable cavity 17. The hammer head 21 is fixed to the outer end of the piston rod 20.

[0029] The transmission assembly 22 includes a pulley and a transmission belt. Two fixed plates 23 are fixed on the left and right surfaces of the feed hopper body 1. The support shaft 15 rotates with the fixed plate 23. The fixed plate 23 effectively supports the support shaft 15, thereby ensuring the stability and use effect of the knocking mechanism. The two pulleys are respectively arranged on the rotating rod 4 and the support shaft 15, and the transmission belt is arranged between the two pulleys.

[0030] There are two relatively fixed limit rods 24 inside the movable chamber 17. The limit rods 24 pass through the movable plate 18. The movable plate 18 slides with the limit rods 24, which effectively play a limiting and guiding role for the movable plate 18, ensuring the stability of the piston rod 20 when it extends outward from the movable chamber 17 and retracts into the movable chamber 17. A servo motor 25 is installed on the rear surface of the feed hopper body 1 through a mounting frame, and the output end of the servo motor 25 is connected to the rear end of the rotating rod 4 on the left.

[0031] Example:

[0032] During use, when the material to be color-sorted is put into the feed hopper body 1, the servo motor 25 is started, and the servo motor 25 drives the rotating rod 4 on the left to rotate. Under the meshing action of the driving gear 6 and the driven gear 7, the rotating rod 4 on the right is driven to rotate synchronously in the opposite direction. The rotation of the rotating rod 4 drives the cam 5 to rotate synchronously.

[0033] When the raised portion of the cam 5 approaches the vibration plate 2, the hinged connection between the vibration plate 2 and the inner wall of the feed hopper body 1 causes the movable end of the vibration plate 2 to lift upward, stretching the first spring 3. When the raised portion of the cam 5 moves away from the vibration plate 2, the elastic action of the first spring 3 pulls the vibration plate 2 back to its initial position, thereby driving the vibration plate 2 to vibrate and beat the material. At the same time, under the action of the vibration plate 2, the first vibrating rod 8 is driven to tamp the material inside the feed hopper body 1.

[0034] As the raised portion of the cam 5 moves away from the vibrating plate 2 and continues to rotate, when the raised portion of the cam 5 rotates to contact the cross bar 11, the cross bar 11 is squeezed downward under the sliding cooperation of the cross bar 11 and the guide rod 10, and the second spring 14 is compressed. Through the cross bars 11 on both sides, the longitudinal rod 12 is driven to move downward synchronously. When the cam 5 continues to rotate until the raised portion moves away from the cross bar 11, the cross bar 11 is pushed upward under the elastic action of the second spring 14, and combined with the longitudinal rod 12, the second vibrating rod 13 is driven upward to tamp the material inside the feed hopper body 1, thereby achieving the purpose of breaking up the material and avoiding mutual squeezing between material particles, so that the material particles are framed together and accumulated in the feed hopper, causing blockage, and the material cannot continuously and stably enter the color sorter.

[0035] The driving assembly 22 drives the support shafts 15 on both sides to rotate synchronously, and the rotation of the support shafts 15 drives the disc 16 to rotate. During the rotation of the disc 16, the hammer head 21 is driven to rotate until it contacts the outer wall of the feed hopper body 1, thereby achieving the purpose of striking the outer wall of the feed hopper body 1, preventing the material from adhering to the inner wall of the feed hopper body 1, ensuring the material discharge effect, and solving the problem that the feed hopper of the existing color sorter does not have any auxiliary mechanism inside, and the accumulated materials are broken up and guided, so that the materials cannot be continuously and stably transported to the inside of the color sorter, affecting the color sorting progress of the materials and the use effect of the color sorter;

[0036] As the disc 16 continues to rotate, the outer wall of the feed hopper body 1 has a limiting and blocking effect on the hammer head 21, causing the piston rod 20 to move toward the inside of the movable chamber 17, thereby driving the movable plate 18 to move along the direction of the limiting rod 24 toward the direction close to the support shaft 15, and compressing the third spring 19. When the disc 16 drives the hammer head 21 away from the feed hopper body 1, under the elastic action of the third spring 19, combined with the movable plate 18, the piston rod 20 is squeezed outward, thereby driving the hammer head 21 to move away from the support shaft 15, making it convenient to continue to knock on the outer wall of the feed hopper body 1.

[0037] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the servo motor 25 in the present invention is purchased on the market, and technical personnel in this field can install and use it according to requirements.
