Description

Technical Field

[0001] This utility model relates to the field of solution metering technology, and in particular to an automatic solution metering and adding controller for intelligent factories. Background Technology

[0002] An automatic liquid metering device is an automated device used for the precise measurement and control of solution volume or flow rate. Relying on sensor detection, an intelligent control system, and actuators working in tandem, it can automatically complete the process of solution extraction, metering, transportation, or proportioning without manual operation. It is widely used in industries such as chemical, pharmaceutical, water treatment, and food processing. Its core advantages lie in improving metering accuracy, increasing production efficiency, and reducing human error, while also enabling continuous operation and data recording, ensuring the stability and traceability of the production process.

[0003] Most automatic solution metering devices currently on the market use pumping to achieve metering functions, but this method has significant limitations in practical applications. The pumping systems of these devices are typically preset with fixed capacity specifications, resulting in a narrow adjustment range and cumbersome operation, making it difficult to flexibly adjust the pumping volume according to actual working conditions. This problem leads to insufficient equipment versatility. When faced with metering tasks involving multiple specifications and batches, not only is it necessary to frequently replace parts or adjust the equipment, but insufficient adjustment precision may also affect metering accuracy, thereby reducing production efficiency, increasing operating costs, and failing to fully meet the diverse requirements of solution pumping metering work. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an automatic metering and adding controller for intelligent factories.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic metering and adding controller for intelligent factories, comprising a dispensing shell, wherein a dispensing hose is disposed inside the dispensing shell, a rotating seat is rotatably connected to the center of the dispensing shell, a through groove is formed on the surface of the rotating seat, and pressure wheels are disposed on both sides of the rotating seat. A rotating shaft is rotatably connected to the center of the pressure wheels, a threaded pin is slidably connected inside the through groove, and a linkage rod is rotatably connected to the outer wall of the threaded pin. The end of the linkage rod is rotatably connected to the rotating shaft, and the dispensing hose is pumped and metered by the rotation of the pressure wheels.

[0006] Preferably, the end of the threaded pin is threaded with a nut, and the end position of the linkage rod is locked by the threaded pin and the screw.

[0007] Preferably, a servo motor is provided on the outer wall of the ingredient container, and a base is fixedly connected to the bottom of the servo motor.

[0008] Preferably, the output end of the servo motor is equipped with a reducer housing, and the servo motor drives the rotating base to rotate through the reducer housing.

[0009] Preferably, the side of the ingredient container has two openings, and a pagoda connector is fixedly connected to the opening.

[0010] Preferably, the inner wall of the ingredient container is provided with an annular groove, and the ingredient hose is embedded inside the annular groove.

[0011] Preferably, a rubber pad is provided around the outer periphery of the pressure roller, and the rubber pad makes flexible pressure contact with the dispensing hose.

[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 equipment uses a servo motor and a reducer housing to regulate the rotation speed and record the number of rotations. Combined with the quantitative pumping characteristic of the pressure wheel per revolution, it achieves precise metering of solution addition, meeting the needs of refined production in smart factories. Furthermore, by adjusting the position of the threaded pin in the through-slot and using a linkage rod to change the radius of the pressure wheel's trajectory, it can adapt to dispensing hoses of different diameters. This allows it to handle diverse metering scenarios without replacing core components, resulting in wider adaptability.

[0014] 2. In this invention, the rubber pad around the outer periphery of the pressure wheel makes flexible contact with the dispensing hose, reducing damage from forced deformation. Combined with the annular groove inside the dispensing shell, this limits the hose's position and prevents it from dislodging from its working position. The base and shock-absorbing pad at the bottom of the servo motor effectively reduce equipment vibration and noise, improving operational stability. The optimized design of each component extends the overall lifespan of the equipment and its core parts, reducing maintenance costs. Attached Figure Description

[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 - Figure 4 As shown, this utility model provides an automatic solution metering and adding controller for intelligent factories, including a dispensing shell 4, a dispensing hose 3 inside the dispensing shell 4, a rotating seat 7 rotatably connected to the center of the dispensing shell 4, a through groove 11 on the surface of the rotating seat 7, pressure wheels 6 on both sides of the rotating seat 7, a rotating shaft 9 rotatably connected to the center of the pressure wheels 6, a threaded pin 10 slidably connected inside the through groove 11, a linkage rod 8 rotatably connected to the outer wall of the threaded pin 10, and the end of the linkage rod 8 rotatably connected to the rotating shaft 9. The dispensing hose 3 is pumped and metered by the rotation of the pressure wheels 6.

[0023] The specific settings and functions of this embodiment are described below. During the intelligent factory generation, one end of the dispensing hose 3 is connected to the solution, and the other end is connected to the container where the solution needs to be added. The servo motor 1 drives the rotating seat 7 to rotate. The rotating seat 7 drives the outer rotating shaft 9 to rotate in a ring through the linkage rod 8. During the rotation of the rotating shaft 9, the dispensing hose 3 on the side wall is compressed, and pumping is performed according to the rotating shaft 9. Each rotation of the rotating shaft 9 pumps a metered amount of solution from the dispensing hose 3, realizing the function of metering while adding solution. The servo motor 1 is controlled to drive the rotating seat 7. The number of rotations controls the pumping capacity of the solution in the dispensing hose 3. To facilitate adjustment of the pumping capacity, dispensing hoses 3 with different diameters can be used for pumping and metering. To match and adapt to the pumping requirements of the dispensing hose 3, the end of the linkage rod 8 is designed to be movable and adjustable. By adjusting the position of the threaded pin 10 in the through groove 11, if the threaded pin 10 is pushed outward, the linkage rod 8 will pull the two pressure wheels 6 together towards the middle. If the threaded pin 10 is adjusted inward, the linkage rod 8 will push the two pressure wheels 6 outward. Adjusting the radius of the running trajectory of the pressure wheels 6 allows them to be adapted to the dispensing hose 3 for pumping and metering.

[0024] Example 2: Figure 1 and Figure 3 As shown, a nut is threaded to the end of the threaded pin 10, and the end position of the linkage rod 8 is locked by the threaded pin 10 and the screw. A servo motor 1 is provided on the outer wall of the dispensing shell 4, and a base 2 is fixedly connected to the bottom of the servo motor 1. A reducer housing 5 is installed at the output end of the servo motor 1, and the servo motor 1 drives the rotating seat 7 to rotate through the reducer housing 5.

[0025] The mixing tank 4 has two openings on its side, and a pagoda connector 12 is fixedly connected to each opening. An annular groove is formed on the inner wall of the mixing tank 4, and the mixing hose 3 is embedded inside the annular groove. A rubber pad is provided around the outer periphery of the pressure roller 6, allowing for flexible pressure contact between the rubber pad and the mixing hose 3.

[0026] The overall effect of this embodiment is as follows: a rubber pad is provided on the outside of the pressure wheel 6 to make it flexibly contact the dispensing hose 3, reducing the degree of forced deformation damage to the dispensing hose 3 and extending the service life of the parts; an annular groove is opened inside the dispensing shell 4 to limit the embedding position of the dispensing hose 3 and prevent it from detaching from the cavity; a base 2 is provided at the bottom of the servo motor 1, and a shock-absorbing pad is provided below the base 2 to reduce the vibration and noise of the equipment operation and improve the stability of the equipment operation; a reducer shell 5 is provided on the side of the dispensing shell 4, which has the function of adjusting the speed and recording the number of revolutions. By pre-setting the added capacity, the metering effect is achieved.

[0027] The device's operation and working principle are as follows: The servo motor 1 on the base 2 drives the rotating seat 7 inside the dispensing shell 4 to rotate via the reducer housing 5. The rotating seat 7 drives the linkage rod 8 through the threaded pin 10 in the through groove 11, which in turn pulls the rotating shafts 9 on both sides and the pressure roller 6 to make a circular motion. The pressure roller 6 flexibly compresses the dispensing hose 3 embedded in the annular groove of the dispensing shell 4 through the rubber pads on its outer periphery. The two ends of the dispensing hose 3 are connected to the solution and the target container respectively through the pagoda connectors 12 on the side of the dispensing shell 4. The pressure roller 6 pumps a quantitative amount of solution into the dispensing hose 3 every one revolution. The pumping capacity can be precisely controlled by controlling the number of revolutions of the rotating seat 7 driven by the servo motor 1. At the same time, the running trajectory radius of the pressure roller 6 can be changed by adjusting the position of the threaded pin 10 in the through groove 11 and by using the linkage rod 8, adapting to dispensing hoses 3 of different diameters to meet diverse metering needs.

[0028] 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.
