Description

Technical Field

[0001] This utility model relates to the technical field of ceramic blank preparation equipment, specifically to a quantitative feeding device for a cement bonding machine used in the production of suspension insulators. Background Technology

[0002] In the production process of suspension insulators, cement bonding is a process to make the cement more compact. The cement bonding machine is the equipment to complete this process. By putting in the binder and using vibration, the binder vibrates and vents air, resulting in good cement molding effect.

[0003] There are still some unresolved technical problems in the existing equipment for feeding materials to the bonding machine. For example, in terms of quantitative control, most devices rely on manual experience to judge the amount of material to be fed, lacking precise metering methods. This results in a large error in the amount of cement fed each time, making it difficult to ensure the consistency of the cement ratio during the bonding process, and thus affecting the bonding quality of the insulators. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a quantitative feeding device for a cement bonding machine used in the production of suspension insulators. The device includes a storage silo, a feeding hopper mounted on the top of the silo, and a feeding pipe connected to the bottom of the silo, with a first on / off valve installed on the feeding pipe. A metering silo is located below the storage silo, with a metering hopper mounted on the top of the metering silo, directly below the feeding pipe. A conveying shaft is rotatably connected inside the metering silo, with helical blades fixed to its outer surface. One end of the conveying shaft extends outside the metering silo and is connected to a reduction motor. A receiving plate is fixed to the bottom of the metering silo, and a main base is located below the receiving plate. A pressure-sensitive weighing device is mounted on the top of the main base, and the receiving plate rests on the pressure-sensitive weighing device. A feeding pipe is connected to the end of the metering silo furthest from the reduction motor, with a second on / off valve installed on the feeding pipe.

[0005] Furthermore, the first opening and closing valve, the second opening and closing valve, the geared motor, and the pressure-sensitive weighing device are electrically connected.

[0006] Furthermore, a drive motor is installed on the top of the storage silo, and the output end of the drive motor is connected to a rotating shaft that extends into the storage silo. A connecting rod is fixed to the outer side of the rotating shaft, and a scraper is fixed to the other end of the connecting rod. The scraper contacts the inner wall of the storage silo.

[0007] Furthermore, the connecting rod is set at a downward angle.

[0008] Furthermore, a water inlet pipe is installed on the top of the storage silo, and the water inlet pipe is connected to the inside of the storage silo.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. By monitoring the weight of the metering bin in real time through a pressure-sensitive weighing device, and linking it with the first and second opening and closing valves and the geared motor, quantitative conveying of cement materials is achieved. Compared with the traditional method of manually judging the amount of material to be dispensed, this device can control the dispensing error within a small range, ensuring that the amount of cement dispensed each time is basically consistent and adjustable, thus guaranteeing the accuracy of the cement ratio during the cement bonding process of suspension insulators.

[0011] 2. The scraper device inside the storage silo can promptly remove cement material adhering to the silo wall, preventing material scaling and blockage, and ensuring the normal flow and continuous discharge of materials within the silo. Simultaneously, through the coordination of the water inlet pipe and various on / off valves, rapid cleaning of the storage silo and metering chamber is achieved. Attached Figure Description

Figure 1 As shown, the system includes a storage silo 1, a material feed hopper 2 installed on top of the storage silo 1, a feeding pipe 3 connected to the bottom of the storage silo 1, and a first on / off valve 4 installed on the feeding pipe 3; a metering silo 5 is located below the storage silo 1, and a metering feed hopper 6 is installed on top of the metering silo 5, directly below the feeding pipe 3; a conveying shaft 7 is rotatably connected inside the metering silo 5, and a spiral blade 8 is fixed to the outer side of the conveying shaft 7; one end of the conveying shaft 7 extends outside the metering silo 5. A geared motor 9 is connected to a conveyor shaft 7. A receiving plate 10 is fixed at the bottom of the metering chamber 5. A main base 12 is set below the receiving plate 10. A pressure-sensitive weighing device 11 is installed on the top of the main base 12. The receiving plate 10 is placed on the pressure-sensitive weighing device 11. A discharge pipe 13 is connected to the end of the metering chamber 5 away from the geared motor 9. A second opening and closing valve 14 is installed on the discharge pipe 13. The first opening and closing valve 4, the second opening and closing valve 14, the geared motor 9 and the pressure-sensitive weighing device 11 are electrically connected.

[0019] The storage bin 1 stores materials, the hopper 2 is used for feeding materials, the feeding pipe 3 and the first on / off valve 4 control the material to be conveyed to the metering bin 5; the metering bin 5 receives materials through the metering hopper 6, the conveying shaft 7 and the spiral blade 8 realize the material conveying under the drive of the geared motor 9, the pressure-sensitive weighing device 11 works with the receiving plate 10 and the main base 12 to measure the weight, the discharge pipe 13 and the second on / off valve 14 control the discharge, and the components are electrically connected to realize automatic linkage.

[0020] like Figure 1 and Figure 2As shown, in this embodiment, a drive motor 15 is installed on the top of the storage silo 1. The output end of the drive motor 15 is connected to a rotating shaft 16 that extends into the storage silo 1. A connecting rod 17 is fixed to the outer side of the rotating shaft 16. The connecting rod 17 is inclined downwards, and a scraper 18 is fixed to the other end of the connecting rod 17. The scraper 18 contacts the inner wall of the storage silo 1. The drive motor 15 can drive the rotating shaft 16, the connecting rod 17, and the scraper 18 to rotate. The scraper 18 contacts the inner wall of the storage silo 1, scraping off the cement material adhering to the silo wall, effectively preventing cement from scaling and adhering to the inner wall of the storage silo 1, and ensuring the flowability of materials in the storage silo 1.

[0021] In this embodiment, a water inlet pipe 19 is installed on the top of the storage silo 1, and the water inlet pipe 19 is connected to the inside of the storage silo 1. The water inlet pipe 19 is connected to the inside of the storage silo 1 and is used to deliver clean water into the storage silo 1 to facilitate rinsing and cleaning of the storage silo 1. With the help of the first on / off valve 4, water can be introduced into the metering chamber 5 for simultaneous cleaning.

[0022] The working principle of this utility model is as follows:

[0023] Cement is added to the storage silo 1 through the feed hopper 2. When it is necessary to feed to the metering silo 5, the first on / off valve 4 is opened, and the cement in the storage silo 1, under the action of gravity, enters the metering silo feed hopper 6 above the metering silo 5 through the feed pipe 3, and then falls into the metering silo 5. During this process, the pressure-sensitive weighing device 11 senses the weight changes of the receiving plate 10 and the metering silo 5 in real time.

[0024] As cement continues to enter the metering hopper 5, the weight sensed by the pressure-sensitive weighing device 11 gradually increases. When the weight change reaches a preset value, the pressure-sensitive weighing device 11 transmits a signal to the control system, which then issues a command to close the first on / off valve 4, stopping the material from the storage hopper 1 to the metering hopper 5. At this point, the amount of cement in the metering hopper 5 reaches the set discharge amount.

[0025] After the first valve 4 closes, the control system issues a command to open the second valve 14 and simultaneously starts the geared motor 9. The output shaft of the geared motor 9 drives the conveyor shaft 7 to rotate, and the spiral blades 8 on the outer side of the conveyor shaft 7 rotate accordingly. The rotation of the spiral blades 8 pushes the cement in the metering bin 5 to be conveyed to the feed pipe 13, which is located above the feed end of the bonding machine. During the cement conveying process, the pressure-sensitive weighing device 11 continuously senses the weight of the metering bin 5. When the weight returns to the initial value, it indicates that all the cement in the metering bin 5 has been conveyed. The pressure-sensitive weighing device 11 transmits a signal to the control system, and the control system issues a command to close the second valve 14, stopping the feeding and completing one quantitative feeding process.

[0026] When cleaning of storage silo 1 and metering silo 5 is required, clean water is supplied to storage silo 1 through water inlet pipe 19. The clean water rinses the walls of storage silo 1. The drive motor 15 is then started, causing the rotating shaft 16 to rotate. The rotating shaft 16, via connecting rod 17, causes the scraper 18 to rotate against the inner wall of storage silo 1, scraping off material adhering to the walls and enhancing the cleaning effect. The first on / off valve 4 is opened, allowing the cleaning water in storage silo 1, along with the scraped material, to flow into metering silo 5 for rinsing. Finally, the second on / off valve 14 is opened to drain the cleaning water from metering silo 5, completing the entire cleaning process.

[0027] During production, the start time and frequency of the drive motor 15 can be set according to the actual situation. The drive motor 15 is started at a set time, which drives the rotating shaft 16, connecting rod 17 and scraper 18 to rotate. The scraper 18 contacts the inner wall of the storage silo 1 and scrapes off the cement material adhering to the silo wall, preventing cement from scaling and sticking to the inner wall of the storage silo 1, and ensuring the flowability of the material in the storage silo 1 and the smoothness of the material discharge.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
