Description

Technical Field

[0001] This utility model belongs to the field of metering feeder technology, specifically a high-efficiency metering feeder for nano-color paste. Background Technology

[0002] As a core piece of equipment specifically designed for the production of nano-color pastes, the high-efficiency metering feeder for nano-color pastes ensures the stability and consistency of the color paste ratio through high-precision metering and automated addition of powder raw materials. This plays a crucial role in the production of photoresist color pastes for LCD display panels—especially in achieving precise metering of red nano-color pastes to ensure the color purity and wide color gamut coverage of the display panels. This device typically includes a feed hopper, feeding rollers, metering units (such as sensors or metering pumps), and a dynamic control system. By optimizing powder dispersion and feeding uniformity, it controls the feeding error within an extremely low range.

[0003] Currently, existing high-efficiency metering feeders for nano-color pastes feed different materials through multiple storage bins. However, each material tends to aggregate individually, resulting in uneven feeding, which prolongs the subsequent mixing time and affects work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency metering feeder for nano-color pastes to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency metering feeder for nano pigments, comprising a storage bin, a guide pipe provided at the bottom of the storage bin, a metering pump installed between the guide pipe and the storage bin, and the metering pump being used to control the feeding amount; A dispersion box is provided at the bottom of the feed pipe. A perforated plate for dispersing the material to the surrounding area is movably connected inside the dispersion box. A dispersion mechanism for improving the uniformity of feeding is provided between the perforated plate and the dispersion box.

[0006] Preferably, the orifice plate is configured as a conical structure; the dispersion mechanism includes a guide frame welded to the top of the inner side of the dispersion box and a connecting column welded at equal angles to the top of the orifice plate, and the connecting column includes a column welded to the top of the orifice plate and a spherical guide block welded to the top of the column, and a guide plate is slidably connected to the bottom of the inner side of the guide frame.

[0007] Preferably, the bottom end of the guide plate is provided with an annular groove that forms a sliding structure with the connecting column, and the annular groove cooperates with the connecting column to make the guide plate move up and down synchronously with the perforated plate.

[0008] Preferably, a return spring is connected between the guide plate and the guide frame.

[0009] Preferably, the bottom end of the orifice plate is welded with guide posts at equal angles, and the inner side of the dispersion box is fixedly connected with a bracket, which includes an annular plate and an L-shaped rod welded at equal angles between the annular plate and the dispersion box.

[0010] Preferably, the top of the bracket is fixed with an inclined plate that matches the guide post at an equal angle.

[0011] Preferably, a servo motor connected to the top wall of the orifice plate is installed at the top of the dispersion box, and the servo motor is used to drive the orifice plate to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a cone-shaped perforated plate to disperse materials to the periphery, preventing accumulation in the center. The dispersing mechanism rotates the perforated plate while simultaneously vibrating it vertically, thus uniformly and quickly dispersing the materials to the periphery, achieving initial mixing. This also prevents materials from adhering and accumulating, which could cause blockages. This method can improve the uniformity of feeding, shorten the subsequent mixing time, and increase work efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a high-efficiency metering feeder for nano pigments, including a storage bin 1, a cover installed at the top of the storage bin 1 to prevent foreign matter from entering and contaminating the material, a guide pipe 2 provided at the bottom of the storage bin 1, and a metering pump 3 installed between the guide pipe 2 and the storage bin 1, the metering pump 3 being used to control the feeding amount. Specifically, the amount of material entering the feed pipe 2 from the storage bin 1 is controlled by the metering pump 3 in order to achieve efficient metering of the material.

[0017] exist Figure 1 , Figure 3 and Figure 6 In the middle: a dispersion box 4 is provided at the bottom of the feed pipe 2. The dispersion box 4 is movably connected to an orifice plate 5 for dispersing the material to the surrounding area. The orifice plate 5 is set as a conical structure.

[0018] Specifically, by setting the orifice plate 5 as a conical structure, the material falling onto the orifice plate 5 will naturally disperse along the inclined surface of the orifice plate 5 to the periphery due to gravity, avoiding accumulation in the center. At the same time, the through holes of the orifice plate 5 are used to disperse the material.

[0019] exist Figure 3 , Figure 4 and Figure 6 In the middle: A dispersion mechanism 6 is provided between the orifice plate 5 and the dispersion box 4 to improve the uniformity of feeding. The dispersion mechanism 6 includes a guide frame 602 welded to the top of the inner side of the dispersion box 4 and a connecting column 606 welded at an equal angle to the top of the orifice plate 5. The connecting column 606 includes a column welded to the top of the orifice plate 5 and a spherical guide block welded to the top of the column. A guide plate 603 is slidably connected to the bottom of the inner side of the guide frame 602. The bottom of the guide plate 603 has an annular groove 605 that forms a sliding structure with the connecting column 606. The annular groove 605 cooperates with the connecting column 606 to make the guide plate 603 move up and down synchronously with the orifice plate 5.

[0020] Specifically, since the perforated plate 5 and the guide plate 603 are slidably connected through the annular groove 605 and the connecting column 606, when the servo motor 601 is working, the output end of the servo motor 601 drives the perforated plate 5 to rotate, so that the centrifugal force generated by the rotation can make the material evenly disperse to the surrounding area, thus achieving the initial mixing of the material.

[0021] exist Figure 3 , Figure 4 and Figure 6 In the middle: A return spring 604 is connected between the guide plate 603 and the guide frame 602. The return spring 604 is used to keep the guide post 609 and the inclined plate 608 in a tight state at all times.

[0022] Specifically, the return spring 604 can keep the guide post 609 and the inclined plate 608 in a constant state of contact.

[0023] exist Figure 1 , Figure 3 , Figure 5 and Figure 6 In the middle: a guide post 609 is welded at the bottom of the orifice plate 5 at equal angles. A bracket 607 is fixedly connected to the inner side of the dispersion box 4. The bracket 607 includes an annular plate and an L-shaped rod welded at equal angles between the annular plate and the dispersion box 4. An inclined plate 608 matching the guide post 609 is fixed at equal angles at the top of the bracket 607. When the guide post 609 slides along the inclined surface of the inclined plate 608, the guide post 609 can move in the vertical direction.

[0024] Specifically, during the rotation of the orifice plate 5, the guide post 609 at the bottom of the orifice plate 5 slides along the inclined surface of the inclined plate 608. Since the guide plate 603 and the guide frame 602 are elastically connected by the return spring 604, the orifice plate 5 can reciprocate vertically during the contact and separation of the guide post 609 and the inclined plate 608. This can accelerate the sliding of materials and prevent materials from adhering and accumulating, thus preventing blockage. This method can shorten the subsequent mixing time and improve work efficiency.

[0025] exist Figure 2 , Figure 3 and Figure 6 In the middle: A servo motor 601 is installed at the top of the dispersion box 4 and is connected to the top wall of the orifice plate 5. The servo motor 601 is used to drive the orifice plate 5 to rotate.

[0026] Specifically, when the servo motor 601 is working, the output end of the servo motor 601 drives the perforated plate 5 to rotate.

[0027] In use, the metering pump 3 controls the amount of material entering the feed pipe 2 from the storage bin 1. Then, a fixed amount of material enters the dispersion box 4 through the feed pipe 2 and falls onto the perforated plate 5. The material falling onto the perforated plate 5 will naturally disperse along the slope of the perforated plate 5 due to gravity, and the through holes of the perforated plate 5 will also help disperse the material. At the same time, the servo motor 601 is started, so that the output end of the servo motor 601 drives the perforated plate 5 to rotate, so that the centrifugal force generated by the rotation can evenly disperse the material to the surrounding area, achieving the initial mixing of the material. During this process, the guide column 609 at the bottom of the perforated plate 5 slides along the slope of the inclined plate 608. Through the elastic action between the guide plate 603 and the guide frame 602, the perforated plate 5 can be vertically shaken during the contact and separation of the guide column 609 and the inclined plate 608, which can accelerate the sliding of the material and prevent the material from adhering and accumulating, causing blockage. Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
