Description

Technical Field

[0002] In the glass bottle manufacturing industry, precise proportioning and uniform mixing of raw materials are crucial for ensuring product quality. Traditional glass bottle raw material mixing equipment generally suffers from insufficient quantitative accuracy, low mixing efficiency, and a lack of automation. On the one hand, the raw material storage and feeding process relies on manual intervention or simple vibration devices, which can easily lead to silo blockage and viscous raw materials sticking to the silo walls, resulting in uneven feeding and affecting the accuracy of subsequent proportioning. On the other hand, the mixing mechanism often uses a single spiral or simple stirring structure, which makes it difficult to guarantee the uniformity of mixing granular or powdery raw materials, and lacks control over the humidity and temperature of the raw materials. Residual moisture can easily lead to raw material clumping or chemical reactions, affecting the quality of the finished glass bottle. Utility Model Content

[0021] 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.

[0022] like Figure 1-3 As shown, this utility model provides an automatic quantitative feeding glass bottle raw material mixing device, including a frame 1, a raw material storage mechanism 3, a quantitative feeding mechanism 4, a mixing mechanism 2, a conveying pipeline 102, and an intelligent control system 101. The raw material storage mechanism 3 includes at least two independent hoppers 301, and a vibrating feeder 401 is provided at the bottom of each hopper 301. The quantitative feeding mechanism 4 includes a screw meter 402, a weighing sensor 406, and a first guide plate 403. The screw meter 402 is connected to the outlet of the vibrating feeder 401, the weighing sensor 406 is located below the screw meter 402, and the first guide plate 403 is installed obliquely at the discharge end of the screw meter 402.

[0023] This embodiment consists of a frame 1, a raw material storage mechanism 3, a quantitative feeding mechanism 4, a mixing mechanism 2, a conveying pipeline 102, and an intelligent control system 101. All parts work together to realize the automatic quantitative feeding and mixing of glass bottle raw materials.

[0024] The raw material storage mechanism 3 includes at least two independent hoppers 301 with a conical structure design. This structure facilitates the smooth downward flow of raw materials under their own weight, preventing accumulation within the hoppers 301. The inner walls of the hoppers 301 are coated with an anti-stick coating, effectively preventing sticky raw materials from adhering to the hopper walls and ensuring smooth flow of raw materials to the bottom of the hoppers 301. A vibrating feeder 401 installed at the bottom of each hopper 301 is connected to the hopper 301 via a spring bracket. The spring bracket serves two purposes: firstly, to dampen shocks and reduce the impact of the vibrating feeder 401 on the hopper 301 during operation; and secondly, to ensure stable operation of the vibrating feeder 401. When feeding is required, the vibrating feeder 401 begins to vibrate, uniformly and continuously conveying the raw materials in the hoppers 301 to the quantitative feeding mechanism 4.

[0025] The screw metering device 402 in the quantitative feeding mechanism 4 is connected to the outlet of the vibrating feeder 401. The screw metering device 402 includes a main screw shaft 404 and an auxiliary screw shaft 405. The diameter of the main screw shaft 404 is larger than that of the auxiliary screw shaft 405, and the two rotate in opposite directions. The main screw shaft 404 is responsible for receiving the raw material from the outlet of the vibrating feeder 401 and performing initial conveying. The auxiliary screw shaft 405 is located outside the main screw shaft 404 and further combs and pushes the raw material through reverse rotation. This design can improve the efficiency and uniformity of raw material conveying and avoid blockage or accumulation of raw material during the conveying process. A weighing sensor 406 installed below the screw metering device 402 weighs the conveyed raw material in real time. When the weighing sensor 406 detects that the weight of the raw material reaches the set quantitative value, it will transmit a signal to the PLC controller in the intelligent control system 101. The PLC controller then controls the vibrating feeder 401 to stop feeding and simultaneously controls the screw metering device 402 to continue working to convey the remaining raw material in the screw metering device 402. The first guide plate 403 (with an angle of 30°-60° with the horizontal plane) installed at the discharge end of the screw meter 402 can guide the quantitative raw material to flow smoothly from the discharge end of the screw meter 402 and enter the mixing mechanism 2 at a certain angle and speed.

[0026] The mixing mechanism 2 includes a conveying chamber 202, at least two double-helix mixing chambers 201 disposed on the conveying chamber 202, a second guide plate 203, and a heating and dehumidifying device 204. The top of each double-helix mixing chamber 201 is connected to a first guide plate 403, and the double-helix mixing chambers 201 are connected to each other through a conveying pipe 102. The second guide plate 203 is spirally distributed along the inner wall of the double-helix mixing chamber 201. The heating and dehumidifying device 204 includes a hot air generator and an annular air duct 206, which is arranged around the middle of the double-helix mixing chamber 201.

[0027] The conveying chamber 202 of the mixing mechanism 2 is equipped with at least two double-helix stirring chambers 201. Each double-helix stirring chamber 201 is connected to a first guide plate 403 at its top, through which the raw material enters the double-helix stirring chamber 201. The double-helix stirring chamber 201 has an inverted frustum-cone structure, which facilitates good flow circulation of the raw material during stirring, improving the mixing effect. The second guide plate 203 (with a helix angle of 45°-60°) spirally distributed along the inner wall of the double-helix stirring chamber 201 guides the raw material to move spirally along the inner wall of the stirring chamber during operation, causing the material to continuously tumble up and down and inside and outside the stirring chamber, achieving thorough mixing. The heating and dehumidifying device 204 includes a hot air generator and an annular air duct 206. The annular air duct 206 surrounds the center of the double-helix mixing chamber 201. Hot air generated by the hot air generator is evenly delivered to the center of the mixing chamber through the annular air duct 206 to heat and dehumidify the raw materials in the mixing chamber. This effectively removes moisture and impurities from the raw materials, ensuring that the raw materials are in a suitable humidity and temperature environment during the mixing process, thus improving the mixing quality. The double-helix mixing chambers 201 are connected by a conveying pipe 102. The conveying pipe 102 is a flexible corrugated pipe with guide spiral blades on its inner wall. Both ends of the corrugated pipe are connected to the quantitative feeding mechanism 4 and the mixing mechanism 2 respectively via quick connectors. The guide spiral blades guide the raw materials to flow smoothly within the conveying pipe 102. The design of the flexible corrugated pipe and quick connectors facilitates the installation and disassembly of the pipe. After the raw materials are initially mixed in one double-helix mixing chamber 201, they can enter the next double-helix mixing chamber 201 through the conveying pipe 102 for further mixing, further improving the uniformity of the mixture. The quick-release discharge valve 205 at the bottom of the double helix mixing chamber 201 is connected to the mixing chamber via a flange. After the raw materials are mixed, the discharge valve 205 is opened, and the mixed raw materials can be discharged from the bottom of the mixing chamber.

[0028] Furthermore, the hopper 301 has a conical structure, and its inner wall is coated with an anti-stick coating. The vibrating feeder 401 is connected to the bottom of the hopper 301 via a spring bracket. The conical structure and anti-stick coating of the hopper 301 effectively prevent raw materials from clogging and sticking within it, ensuring a continuous and stable supply of raw materials to the quantitative feeding mechanism 4. The vibrating feeder 401 is mounted via a spring bracket, reducing the impact of vibration on the hopper 301, ensuring the stability of the feeding process, and avoiding inaccurate subsequent quantitative feeding due to uneven feeding.

[0029] Furthermore, the spiral meter 402 includes a main spiral shaft 404 and an auxiliary spiral shaft 405. The diameter of the main spiral shaft 404 is larger than that of the auxiliary spiral shaft 405, and the two rotate in opposite directions. The angle between the first guide plate 403 and the horizontal plane is 30°-60°.

[0030] The first guide plate 403 is installed at an angle of 30°-60°, which can reasonably guide the quantitative raw materials into the mixing mechanism 2, avoid the accumulation or splashing of raw materials at the discharge end, and ensure that the raw materials enter the subsequent mixing process accurately and smoothly.

[0031] The main screw shaft 404 and auxiliary screw shaft 405 of the screw meter 402 rotate in opposite directions, enabling efficient and uniform delivery of raw materials. Combined with real-time monitoring by the weighing sensor 406 below, accurate measurement of the raw materials is achieved. When the set quantitative value is reached, the intelligent control system 101 promptly controls the feeding and metering equipment to ensure minimal weight error for each feeding, improve the mixing accuracy of the raw materials, and thus guarantee the quality stability of the glass bottle raw material mixture.

[0032] Furthermore, the double-helix stirring chamber 201 has an inverted frustum-shaped structure, and the helix angle of the second guide plate 203 is 45°-60°. The air outlet of the hot air generator delivers air evenly to the center of the stirring chamber through the annular air duct 206. The inverted frustum-shaped structure of the double-helix stirring chamber 201 and the second guide plate 203 (helix angle 45°-60°) on the inner wall work together to create a complex helical motion trajectory for the raw materials during stirring, increasing the contact area and mixing opportunities between the materials, and significantly improving mixing efficiency and uniformity. Whether the raw materials are granular or powdery, they can be fully mixed under the action of double-helix stirring and the guide plate, meeting the requirements for high-quality mixing of raw materials for glass bottles.

[0033] Furthermore, the intelligent control system 101 includes a PLC controller, a touch screen, and a sensor group. The sensor group includes a weighing sensor 406, a temperature sensor, a humidity sensor, and a fault alarm module. The PLC controller is electrically connected to the vibrating feeder 401, the screw metering device 402, the double screw mixing chamber 201, and the heating and dehumidification device 204, respectively. The fault alarm module is signal-connected to the sensor group.

[0034] The intelligent control system 101 includes a PLC controller, a touch screen, and a sensor group. The weighing sensor 406 in the sensor group monitors the weight of the raw materials in real time during the quantitative feeding process; the temperature and humidity sensors monitor the temperature and humidity within the mixing mechanism 2; and the fault alarm module monitors the working status of each component in real time. The PLC controller is electrically connected to the vibrating feeder 401, the screw metering device 402, the double-helix mixing chamber 201, and the heating and dehumidifying device 204, receiving signals from the sensor group and controlling each component according to preset programs and parameters. For example, it controls the start and stop of the vibrating feeder 401 and the screw metering device 402 based on the signal from the weighing sensor 406, and adjusts the working status of the heating and dehumidifying device 204 based on the signals from the temperature and humidity sensors. The touch screen provides a human-machine interface for operators, allowing them to set parameters such as the quantitative value of the raw materials, mixing time, and heating temperature, while simultaneously viewing the equipment's working status and various monitoring data. When the fault alarm module detects an abnormality in the equipment, it will promptly issue an alarm signal, facilitating timely troubleshooting and handling by the operator.

[0035] Furthermore, a quick-release discharge valve 205 is installed at the bottom of the double-helix mixing chamber 201, and the discharge valve 205 is connected to the mixing chamber via a flange. The quick-release discharge valve 205 at the bottom of the double-helix mixing chamber 201 is connected via a flange, and the conveying pipe 102 uses a flexible corrugated pipe and quick couplings. These designs make the equipment more convenient and quick to maintain and clean. When it is necessary to clean the inside of the mixing chamber or to inspect the discharge valve 205 and the conveying pipe 102, the relevant components can be quickly disassembled, improving the maintenance efficiency of the equipment and reducing maintenance time and costs.

[0036] Furthermore, the conveying pipe 102 is a flexible corrugated pipe with guide spiral blades installed on its inner wall. Both ends of the corrugated pipe are connected to the quantitative feeding mechanism 4 and the mixing mechanism 2 respectively via quick-connect couplings. The flexible corrugated pipe and guide spiral blade design of the conveying pipe 102 not only accommodates slight vibrations and displacements during equipment operation, avoiding pipe damage caused by rigid connections, but also ensures stable flow of the raw materials during transport. Simultaneously, the use of quick-connect couplings facilitates the connection and disassembly of the pipe to the quantitative feeding mechanism 4 and the mixing mechanism 2, simplifying equipment installation and layout adjustments, and improving the equipment's flexibility and applicability.
