Description

Technical Field

[0001] This utility model relates to the field of material handling and automation equipment technology, specifically a zircon sand quantitative batching and dispensing device. Background Technology

[0002] In industrial production, with the expanding applications of zircon sand, the accuracy and efficiency of its batching and dispensing processes have become crucial factors affecting product quality. Due to its high specific gravity, poor flowability, and tendency to clump, zircon sand places higher demands on the design of dispensing and metering devices in automated batching systems. To meet the needs of different application scenarios, zircon sand often requires precise proportioning with other trace components, further posing challenges to the functionality and completeness of the batching system.

[0003] A search revealed a concrete aggregate batching system with patent number CN111452221B. This system, by incorporating a receiving and distributing device, a weighing and feeding mechanism, and a mixer, utilizes a combination of a rotating hopper and a suspended weighing device to achieve automatic distribution and metered delivery of different aggregate materials. However, this solution is primarily designed for concrete aggregates with larger particles and better flowability. For zircon sand, which has a high specific gravity, poor flowability, and is prone to agglomeration, its distribution structure struggles to guarantee accurate metering and smooth feeding in practical applications, easily leading to material blockage or significant metering errors.

[0004] Furthermore, the system does not involve precise control over trace additives, and zircon sand often needs to be compounded with other trace components in certain specific applications, thus limiting its applicability.

[0005] Therefore, based on the above problems, the existing technology needs to be further improved to meet the actual needs of zircon sand batching and packaging. Utility Model Content

[0030] 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.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0033] like Figures 1 to 5 As shown, this embodiment provides a zircon sand quantitative batching and dispensing device, including: a support frame 1 for supporting components; a vibrating feeding module 2, disposed above the support frame 1 for vibrating the zircon sand to move forward; a dispensing and metering unit 3, disposed below the vibrating feeding module 2 and above the support frame 1 for dispensing the zircon sand; a trace addition component 4, located on one side of the dispensing and metering unit 3 and above the support frame 1 for mixing trace components with the zircon sand; and a dispensing and output mechanism 5, consisting of two sets connected to one side of the trace addition component 4.

[0034] In this embodiment, the dispensing and metering unit 3 and the micro-addition component 4 constitute a zircon sand quantitative dispensing and packaging device according to this application.

[0035] It should be noted that the support frame 1 is composed of multiple sets of aluminum alloy profiles, and the connection between each module adopts a standardized bolt hole design, which facilitates the independent installation and maintenance of each functional module. The support frame 1 supports each functional module, the vibrating feeding module 2 causes the zircon sand to flow forward through high-frequency vibration, the dispensing and metering unit 3 evenly distributes and accurately weighs the material, the micro-addition component 4 adds and mixes the trace components in proportion, and the dispensing and output mechanism 5 completes the final material dispensing.

[0036] In addition, in this embodiment, zircon sand raw material is first poured onto the vibrating plate 21, and then the vibration driver 22 is started. The vibration driver 22 generates high-frequency vibration and transmits it to the vibrating plate 21. The zircon sand will move smoothly to one side through the vibration of the vibrating plate 21. At the same time, the damping spring 23 and the spring plate 24 provide damping.

[0037] Specifically, the vibration feeding module 2 includes: a vibration plate 21, which is mounted on the support frame 1; a vibration driver 22, which is fixed to the bottom of the vibration plate 21; two sets of shock-absorbing damping springs 23, one end of which is connected to the bottom of the vibration plate 21 and the other end of which is connected to the support frame 1; and a spring plate 24, which is located at the center of the bottom of the vibration plate 21.

[0038] In this embodiment, the upper surface of the vibrating plate 21 is coated with a polytetrafluoroethylene coating, which significantly reduces the friction between the zircon sand and the upper surface, avoiding the clogging problem caused by poor flowability. The vibration driver 22 generates high-frequency vibration, and the vibrating plate 21 transmits the vibration to the zircon sand. The damping spring 23 reduces the transmission of vibration to the support frame 1, and the spring plate 24 enhances the vibration stability, ensuring smooth material flow. Example

[0039] Based on Example 1, zircon sand then enters the rotating distribution plate 33 from one side of the vibrating plate 21. When the weight sensor (not shown in the figure) senses that the zircon sand has reached the preset weight, the controller (not shown in the figure) will start the drive motor 32. The output of the drive motor 32 drives the rotating distribution plate 33 to rotate. The centrifugal force generated by the rotation of the rotating distribution plate 33 will throw the zircon sand to the discharge ports on both sides of the distribution bucket 31. The zircon sand will then enter the conveying pipe 34 from the discharge port.

[0040] Specifically, the material dispensing and metering unit 3 includes: a dispensing hopper 31, which is mounted on the support frame 1; a drive motor 32, which is mounted inside the dispensing hopper 31; a rotating dispensing disc 33, which is rotatably mounted inside the dispensing hopper 31 and whose bottom is connected to the output end of the drive motor 32; and two sets of conveying pipes 34, which are respectively connected to the outer walls of both sides of the dispensing hopper 31.

[0041] As a preferred embodiment, the ceramic anti-stick coating on the surface of the rotating dispensing disc 33 effectively reduces the adhesion of zircon sand, ensuring that the disc surface remains clean after each dispensing operation. The drive motor 32 drives the rotating dispensing disc 33 to rotate, evenly distributing the zircon sand entering the dispensing hopper 31 to the conveying pipe 34, achieving continuous and stable material conveying.

[0042] Specifically, the material dispensing and metering unit 3 includes: material dispensing bucket 31 with discharge ports on both sides of the upper end, and a top platform of rotating material dispensing disc 33 with a slope that slopes from the center to the outer periphery.

[0043] The sloping design at the top of the rotating material distribution plate 33 helps to distribute materials evenly, and the discharge ports on both sides of the upper end of the material distribution bucket 31 ensure that materials smoothly enter the conveying pipe 34, achieving efficient material distribution. Example

[0044] Based on Example 2, zircon sand enters the mixing chamber 47 from the conveying pipe 34. At the same time, the user can add trace additives from the feed inlet 45. Then, the servo motor 41 is started. The output end of the servo motor 41 drives the first bevel gear 42 to rotate. The first bevel gear 42 meshes with the second bevel gears 43 on both sides to rotate. The second bevel gears 43 are connected to the spiral blades 46 through the rotating rod. The spiral blades 46 rotate and stir the trace additives into the mixing chamber 47. Inside the mixing chamber 47, the zircon sand and trace additives are fully mixed together.

[0045] Specifically, the micro-addition component 4 includes: a servo motor 41, mounted on the support frame 1; a first bevel gear 42, connected to the output end of the servo motor 41; two sets of second bevel gears 43, meshing with the first bevel gear 42; two sets of micro-delivery pipes 44, located on both sides of the servo motor 41; two sets of feed inlets 45, located on the upper part of the micro-delivery pipes 44; two sets of spiral blades 46, one end of which is connected to the second bevel gear 43 and rotates inside the micro-delivery pipes 44; and two sets of mixing bins 47, with flanges fixed to the side of the micro-delivery pipes 44 away from the servo motor 41.

[0046] In this embodiment, the mixing bin 47 and the micro-transmission pipeline 44 are connected by a flange, and a sealing gasket is used to ensure that there is no leakage at the connection, thus ensuring the delivery accuracy of the micro-additive. The servo motor 41 drives the first bevel gear 42 to rotate, which in turn drives the second bevel gear 43 to rotate. The spiral blade 46 rotates in the micro-transmission pipeline 44, delivering the micro-component from the feed inlet 45 to the mixing bin 47 and mixing it with the main material.

[0047] Specifically, the bottom surface of the mixing hopper 47 is a slope that slopes from near the conveying pipe 34 to the discharge pipe 51, which is used to mix the materials and allow them to flow to the bottom discharge port.

[0048] In this embodiment, the internal ramp design of the mixing hopper 47 ensures that the mixed material flows smoothly to the bottom outlet, avoiding residue and blockage problems and ensuring smooth material output. Example

[0049] Based on Example 3, the final mixture flows out from the discharge pipe 51 into the dispensing funnel 52. The user places the container at the bottom of the discharge outlet 54 and controls the flow rate of the mixture by adjusting the opening size of the pneumatic valve 53.

[0050] Specifically, the dispensing output mechanism 5 includes: a discharge pipe 51, which is located on one side of the mixing silo 47 and connected to the discharge port at the bottom of the mixing silo 47; a dispensing funnel 52, which is located on the support frame 1 and below the discharge pipe 51; a pneumatic valve 53, which is located below the dispensing funnel 52 and is used to control the output speed of the material; and a discharge outlet 54, which is located at the bottom of the pneumatic valve 53.

[0051] With this setup, the mixed material enters the dispensing funnel 52 through the discharge pipe 51, the pneumatic valve 53 controls the material output speed, and the discharge outlet 54 guides the material into the target container to achieve stable dispensing.

[0052] It should also be understood that the vibration actuator 22, drive motor 32, servo motor 41, pneumatic valve 53, weight sensor and controller are all common knowledge in the field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0053] In actual use, zircon sand is first poured onto the vibrating plate 21, and then the vibration driver 22 is started. The vibration driver 22 generates high-frequency vibrations that are transmitted to the vibrating plate 21. The zircon sand will move smoothly to one side through the vibration of the vibrating plate 21, while the damping spring 23 and spring plate 24 provide shock absorption. Subsequently, the zircon sand enters the rotating distribution plate 33 from one side of the vibrating plate 21. When the weight sensor detects that the zircon sand has reached the preset weight, the controller will start the drive motor 32. The output of the drive motor 32 drives the rotating distribution plate 33 to rotate. The centrifugal force generated by the rotation of the rotating distribution plate 33 will throw the zircon sand to the discharge ports on both sides of the distribution bucket 31, and the zircon sand will then enter the conveying pipe 34 from the discharge ports. Zircon sand then enters the mixing chamber 47 through the conveying pipe 34. Simultaneously, the user can add trace additives through the inlet 45. The servo motor 41 is then activated, driving the first bevel gear 42 to rotate. The first bevel gear 42 meshes with the second bevel gears 43 on both sides, which rotate. The second bevel gears 43 are connected to the spiral blades 46 via a rotating rod. The spiral blades 46 rotate and agitate the trace additives into the mixing chamber 47, where the zircon sand and trace additives are thoroughly mixed. Finally, the mixture flows out through the outlet pipe 51 into the dispensing funnel 52. The user places the container at the bottom of the discharge outlet 54 and controls the flow rate of the mixture by adjusting the opening size of the pneumatic valve 53.

[0054] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
