Description

Technical Field

[0001] This utility model relates to the field of quantity statistics technology, and in particular to an automatic metering device for glass ball raw materials. Background Technology

[0002] The production process of glass beads typically includes main steps such as raw material preparation, mixing, melting, shaping, and annealing. First, based on the performance requirements of the glass beads, main raw materials such as quartz sand, soda ash, and limestone, as well as auxiliary raw materials such as clarifying agents and colorants, are selected and screened and crushed to ensure that the particle size and purity of the raw materials meet production requirements. Then, the various raw materials are precisely weighed and thoroughly mixed in a specific ratio to form a homogeneous mixture. Next, the mixture is placed in a high-temperature furnace for melting, allowing it to reach a certain temperature and viscosity to form a homogeneous molten glass. Finally, using specialized shaping equipment, the molten glass is shaped into glass beads.

[0003] However, traditional methods of metering raw materials for glass beads are limited by their technical capabilities and equipment structure, making it difficult to achieve rapid and orderly material transport. When faced with a large volume of raw material metering, the transport process is often chaotic and disorganized, with poor coordination between various stages, resulting in extremely slow metering speed and very low overall efficiency. Moreover, traditional methods lack precision in controlling the quantity of raw materials transported each time, and are easily affected by various factors such as material accumulation and uneven friction, leading to deviations in the transport volume. Consequently, the final metering results fail to meet the stringent production requirements for precise proportions of glass bead raw materials, seriously affecting the production quality and stability of glass beads. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic metering device for glass ball raw materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic metering device for glass ball raw materials, comprising a first positioning seat and a second positioning seat, wherein a metering cone rod is rotatably connected between the first positioning seat and the second positioning seat. The metering cone rod is a conical column with one end thicker than the other. The surface of the metering cone rod is provided with threaded grooves with gradually changing pitch. The spacing of the threaded grooves near the thick end of the metering cone rod increases, and the spacing of the threaded grooves near the thin end of the metering cone rod decreases. An encoder motor is installed on the outside of the second positioning seat. The output end of the encoder motor drives the metering cone rod to rotate through a belt mechanism, and the raw material is transported from the thin end to the thick end of the metering cone rod.

[0006] Preferably, a positioning frame is installed at the bottom of the first positioning seat and the second positioning seat, and a conveyor belt is provided on the upper surface of the positioning frame.

[0007] Preferably, limit frames are installed at equal intervals on the upper surface of the positioning frame, and the raw material passes through the inside of the limit frames.

[0008] Preferably, a limiting post is inserted at the corner of the limiting frame.

[0009] Preferably, the outer surface of the metering cone is coated with a lubricating coating, and fans are installed on both sides of the conveyor belt.

[0010] Preferably, a plastic film is installed on the outer wall of the limiting post, and the limiting post is used for guiding the conveying of raw materials.

[0011] Preferably, both the first positioning seat and the second positioning seat are threadedly connected to the first positioning seat by screws.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the special conical design of the measuring cone and the threaded groove with gradually changing pitch, combined with the counting function of the encoder motor, achieve precise quantity measurement of regularly shaped raw materials. The structural change of the measuring cone from the thin end to the thick end allows the raw materials to be arranged sequentially and transported at stable intervals. The encoder motor accurately records the number of rotations, delivering one raw material per rotation, greatly improving the accuracy and efficiency of measurement and meeting the production requirements for precise proportioning of glass ball raw materials.

[0014] 2. This utility model incorporates auxiliary structures such as a positioning frame, a limiting frame, limiting posts, and lubricating coating. The limiting frame and limiting posts effectively restrict the position of the raw materials during transportation, preventing them from detaching from the conveyor belt and ensuring conveying stability. The plastic film on the outside of the limiting posts serves as a dust and windproof barrier, preventing external factors from interfering with the raw materials. The lubricating coating applied to the outside of the metering cone reduces friction between the raw materials and the cone, preventing blockages and ensuring a smooth and stable metering and feeding process, thus improving the reliability of the equipment.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-4 As shown, this utility model provides an automatic metering device for glass ball raw materials, including a first positioning seat 3 and a second positioning seat 5. A metering cone rod 4 is rotatably connected between the first positioning seat 3 and the second positioning seat 5. The metering cone rod 4 is a conical column that is thicker at one end and thinner at the other. The surface of the metering cone rod 4 is provided with threaded grooves with gradually changing pitch. The spacing of the threaded grooves increases near the thick end of the metering cone rod 4 and decreases near the thin end of the metering cone rod 4. An encoder motor 6 is installed on the outside of the second positioning seat 5. The output end of the encoder motor 6 drives the metering cone rod 4 to rotate through a belt mechanism, and the raw material is transported from the thin end to the thick end of the metering cone rod 4.

[0023] The specific settings and functions of this embodiment are described below. This device is used to measure the quantity of regularly shaped raw materials. The raw materials are placed on the upper surface of the conveyor belt 1 and transported by the conveyor belt 1 to the measuring cone 4. The raw materials first come into contact with the thinner end of the measuring cone 4 and accumulate at the thinner end of the measuring cone 4 to await transport. As the raw materials continue to be transported forward, the outer diameter of the measuring cone 4 gradually increases, allowing it to fit the surface of the raw materials. At this time, the side gap of the measuring cone 4 can only allow one raw material to pass through. Then, the threaded groove on the outer side of the measuring cone 4 gradually widens, extending the length through which a single raw material passes, and also ensuring that the raw materials are transported normally under a larger thread pitch. At this time, each rotation of the measuring cone 4 can transport a single raw material to the other end, making it easier to count the quantity. At the same time, the encoder motor 6 has a counting capability, and the number of rotations of the measuring cone 4 can also be known through the feedback value of the driver, thereby achieving the measurement effect.

[0024] Example 2: Figure 1 and Figure 2As shown, positioning frames 2 are installed at the bottom of the first positioning seat 3 and the second positioning seat 5, and a conveyor belt 1 is provided on the upper surface of the positioning frame 2. Limiting frames 7 are installed at equal intervals on the upper surface of the positioning frame 2, and the raw material passes through the inside of the limiting frames 7. Limiting posts 8 are inserted at the corner positions of the limiting frames 7. The outer surface of the metering cone rod 4 is coated with lubricating paint, and fans are provided on both sides of the conveyor belt 1. A plastic film is installed on the outer wall of the limiting post 8, and the limiting post 8 is used for guiding the conveying of the raw material. The first positioning seat 3 and the second positioning seat 5 are both threadedly connected to the first positioning seat 3 by screws.

[0025] The overall effect of this embodiment is as follows: In order to limit the quantitative transportation of raw materials under the dual action of conveyor belt 1 and metering cone 4, and at the same time to prevent the raw materials from being detached from conveyor belt 1 due to the limiting effect of metering cone 4, limiting frames 7 are set on the outside of positioning frame 2. Multiple limiting frames 7 are connected to each other by limiting posts 8. The limiting posts 8 are located at one end of metering cone 4 to ensure normal contact between raw materials and metering cone 4. The four limiting posts 8 on the outside limit the raw materials. The installation of plastic film can also achieve dust and wind protection on the outside, preventing the raw materials from detaching from the limiting position. The outer wall of metering cone 4 is coated with lubricating paint to reduce the frictional resistance between raw materials and metering cone 4, ensuring normal passage of raw materials and avoiding blockage problems during metering and feeding.

[0026] The method of use and working principle of this device: First, the raw materials with regular shapes are placed on the conveyor belt 1. The conveyor belt 1 drives the raw materials to the metering cone 4. The raw materials first arrive at the narrow end of the metering cone 4 and accumulate there to wait for subsequent transportation.

[0027] Secondly, as the raw material continues to move forward, the outer diameter of the metering cone rod 4 gradually increases, and its side gap is reduced to allow only one raw material to pass through, so that the raw materials are arranged in sequence, creating conditions for subsequent individual metering.

[0028] Then, the outer threaded groove of the metering cone 4 gradually widens, extending the length through which a single material passes and ensuring its normal conveying under large thread pitch. The encoder motor 6 drives the metering cone 4 to rotate via a belt mechanism, transporting one material to the other end with each revolution. Using the counting capability of the encoder motor 6 and the feedback value from the driver, the number of revolutions of the metering cone 4 is counted, thus completing the measurement of the quantity of materials.

[0029] Finally, the limiting frame 7 and limiting post 8 on the positioning frame 2 limit the raw material to prevent it from falling off the conveyor belt 1. The plastic film on the outside of some of the limiting posts 8 is dustproof and windproof. The lubricating coating on the outer surface of the metering cone rod 4 reduces frictional resistance, avoids raw material blockage, and ensures the smooth passage of raw materials and the smooth metering and feeding.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
