Description

Technical Field

[0001] This utility model relates to the field of cable material mixing technology, and more specifically, to a metering device for mixing cable materials. Background Technology

[0002] Currently, most cable insulation materials are mainly composed of various types of materials such as rubber, plastic, and nylon. Cable insulation materials can be divided into thermoplastic and thermosetting cable materials, and their proportioning methods are different. When making thermoplastic cable materials, liquid plasticizers and stabilizers are needed to improve the performance of the cable.

[0003] In Chinese utility model patents, such as CN215849034U, this utility model discloses a mixing device for accurately measuring cable insulation material. This utility model is equipped with a mixing box, a second motor, and a metering box. During the mixing process, the telescopic block is adjusted to reach the required proportion and height. The cover is opened, and the material falls onto the top of the metering plate. The mixing presses the spring, causing the metering plate to move downward. When the lever plate touches the button, the cover is closed. The button pushes one end of the lever plate upward, and the other end of the lever plate presses the semicircular block downward, causing the semicircular opening to open. The material falls from the semicircular opening into the mixing box, achieving the effect of accurate measurement.

[0004] However, when the above technology is used, when the lever plate touches the button, the screw rod driven by the second motor reverses to close the cover. When the cover closes, it cannot quickly stop the material from falling, causing some material to still fall into the metering box during the closing process, resulting in a difference in the metering result. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a metering device for mixing cable materials. The technical problem to be solved by this utility model is that when the baffle is closed, it cannot quickly stop the falling of raw materials, resulting in some raw materials still falling into the metering box during the closing process of the baffle, resulting in a difference in the metering result.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A metering device for mixing cable materials includes a mixing cylinder, a stirring mechanism installed inside the mixing cylinder, a discharge pipe fixed to the bottom surface of the mixing cylinder, multiple metering barrels symmetrically fixed to and connected to the top surface of the mixing cylinder, multiple storage boxes symmetrically installed on the outer side of the mixing cylinder, each metering barrel being connected to a corresponding storage box via a feed pipe, a discharge pipe fixed to the bottom end of each metering barrel, a first solenoid valve installed on each feed pipe, a second solenoid valve installed on each discharge pipe, a threaded seat slidably connected to the top surface of each metering barrel, each metering barrel driving the threaded seat to slide up and down via a driving mechanism, a piston fixedly installed on the bottom surface of each threaded seat via multiple push rods, and each piston being slidably connected to the inner wall of the corresponding threaded seat, and a metering mechanism installed on the outer side of each metering barrel.

[0008] like Figure 1-4 As shown, the specific implementation method is as follows: by setting up a metering barrel, a piston, a first solenoid valve, a second solenoid valve, a feed pipe, and a discharge pipe, the alternating closing and opening of the first and second solenoid valves, in conjunction with the sliding of the piston, allows the raw material in the feed pipe to be drawn into the metering barrel through the feed pipe, and the raw material to be pushed into the mixing cylinder by the sliding of the piston. During this process, the alternating closing and opening of the first and second solenoid valves prevents the raw material in the storage tank from sliding into the metering barrel due to gravity, thereby achieving accurate metering.

[0009] In a preferred embodiment, each of the metering mechanisms includes a metering plate, and each metering plate is fixedly installed on the outside of the metering barrel. A plurality of electric telescopic rods are symmetrically installed on the top surface of the mixing barrel. An indicator strip is fixedly installed on the outside of the extension end of each electric telescopic rod, and each indicator strip is slidably connected inside the metering plate. A top plate is fixedly installed at the top end of the extension end of each electric telescopic rod. A button is installed at the bottom end of each top plate. An extrusion rod is fixedly installed on the top surface of each threaded seat, and each button is located directly above the extrusion rod at the corresponding position.

[0010] In a preferred embodiment, each of the drive mechanisms includes a second motor, and each second motor is fixedly mounted on the top surface of the metering barrel at the corresponding position. The output shaft of each second motor is connected to a threaded rod, and each threaded rod is threadedly connected to a threaded seat at the corresponding position.

[0011] In a preferred embodiment, the stirring mechanism includes a first motor, which is fixedly mounted on the top surface of the mixing cylinder. The output shaft of the first motor passes through the mixing cylinder and is fitted with a stirring rod. Multiple stirring shafts are fixedly mounted on the outer side of the stirring rod.

[0012] In a preferred embodiment, a baffle is fixedly installed at the top of each threaded rod, and the diameter of each baffle is greater than the diameter of the threaded rod.

[0013] In a preferred embodiment, each of the metering plates has a scale bar on its outer side, and a support is fixedly installed on the bottom surface of the mixing cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a first solenoid valve, a second solenoid valve, a piston, a threaded rod, a threaded seat, etc., realizes that the rotation of the threaded rod drives the threaded seat to push the piston to slide. With the alternating opening and closing of the first solenoid valve and the second solenoid valve, the raw material in the storage box is drawn into the metering barrel and pushed into the mixing cylinder by the sliding piston. During this process, the raw material will not enter the metering barrel due to gravity during the closing and opening of the first solenoid valve, thus ensuring the accuracy of the metering.

[0016] 2. This utility model, by setting up devices such as an electric telescopic rod, an indicator strip, and a metering plate, realizes that the electric telescopic rod drives the indicator strip to slide on the metering plate, and the scale on the metering plate can be used to determine the amount of raw material injected into the metering barrel, thereby achieving the purpose of accurate measurement.

[0017] In summary, this utility model is simple to operate and can achieve accurate measurement and injection of raw materials. At the same time, when the raw materials pass through the first solenoid valve, the closing and opening of the first solenoid valve prevents the raw materials from entering the metering tank due to gravity, thus ensuring the accuracy of measurement.

Detailed Implementation

[0023] 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.

[0024] Reference Figure 1-4 A metering device for mixing cable materials includes a mixing cylinder 1, a stirring mechanism installed inside the mixing cylinder 1, a discharge pipe 3 fixed and connected to the bottom surface of the mixing cylinder 1, multiple metering barrels 5 symmetrically fixed and connected to the top surface of the mixing cylinder 1, multiple storage boxes 4 symmetrically installed on the outside of the mixing cylinder 1, each metering barrel 5 being connected to a corresponding storage box 4 via a feed pipe 9, each metering barrel 5 having a fixed and connected discharge pipe 10 at its bottom end, each feed pipe 9 having a first solenoid valve 11 installed on it, each discharge pipe 10 having a second solenoid valve 12 installed on it, each metering barrel 5 having a threaded seat 15 slidably connected to its top surface, each metering barrel 5 having its threaded seat 15 driven to slide up and down by a driving mechanism, each threaded seat 15 having a piston 24 fixedly installed on its bottom surface via multiple push rods 14, and each piston 24 being slidably connected to the inner wall of the corresponding threaded seat 15, and each metering barrel 5 having a metering mechanism installed on its outside.

[0025] like Figure 1-4 As shown, the specific implementation method is as follows: by setting up a metering tank 5, a piston 24, a first solenoid valve 11, a second solenoid valve 12, a feed pipe 9, and a discharge pipe 10, the alternating closing and opening of the first solenoid valve 11 and the second solenoid valve 12, in conjunction with the sliding of the piston 24, allows the raw material in the feed pipe 3 to be drawn into the metering tank 5 through the feed pipe 9, and the raw material to be pushed into the mixing cylinder 1 by the sliding of the piston 24. During this process, the alternating closing and opening of the first solenoid valve 11 and the second solenoid valve 12 prevents the raw material in the storage tank 4 from sliding into the metering tank 5 due to gravity, thereby achieving accurate metering.

[0026] Each metering mechanism includes a metering plate 21, and each metering plate 21 is fixedly installed on the outside of the metering barrel 5. Multiple electric telescopic rods 19 are symmetrically installed on the top surface of the mixing barrel 1. An indicator strip 20 is fixedly installed on the outside of the extension end of each electric telescopic rod 19, and each indicator strip 20 is slidably connected inside the metering plate 21. A top plate 22 is fixedly installed at the top of the extension end of each electric telescopic rod 19, and a button 23 is installed at the bottom of each top plate 22. A pressing rod 16 is fixedly installed on the top surface of each threaded seat 15, and each button 23 is located directly above the corresponding pressing rod 16. It is worth noting that the button 23 can control the forward and reverse rotation of the second motor 13. The indicator strip 20 points to the outside of the metering plate 21, making it easy to observe and extend the precise position of the electric telescopic rod 19, thereby facilitating accurate measurement.

[0027] Each drive mechanism includes a second motor 13, and each second motor 13 is fixedly installed on the top surface of the corresponding metering barrel 5. The output shaft of each second motor 13 is connected to a threaded rod 17, and each threaded rod 17 is threadedly connected to a corresponding threaded seat 15. The rotation of the threaded rod 17 can drive the threaded seat 15 to slide. It is worth noting that multiple push rods 14 pass through the metering barrel 5, and the multiple push rods 14 limit the threaded seat 15, preventing it from rotating.

[0028] The stirring mechanism includes a first motor 6, which is fixedly installed on the top surface of the mixing cylinder 1. The output shaft of the first motor 6 passes through the mixing cylinder 1 and is equipped with a stirring rod 7. Multiple stirring shafts 8 are fixedly installed on the outside of the stirring rod 7.

[0029] Each threaded rod 17 has a baffle 18 fixedly installed at its top end, and the diameter of each baffle 18 is greater than the diameter of the threaded rod 17. The baffle 18 limits the threaded rod 17 so that it cannot be dislodged from the threaded rod 17.

[0030] Each measuring plate 21 has a scale strip on its outer side, and a support base 2 is fixedly installed on the bottom surface of the mixing cylinder 1.

[0031] In use, this invention first starts by activating the first motor 6 to rotate the stirring rod 7 and the stirring shaft 8, thereby rotating the raw materials in the mixing drum 1. Simultaneously, the electric telescopic rod 19 can be activated to move. The indicator strip 20, which is fixedly installed at the extension end of the electric telescopic rod 19, slides within the metering plate 21, allowing for precise adjustment of the raw material injection amount. Once adjusted, the second motor 13 can be activated to rotate the threaded rod 17. The rotation of the threaded rod 17 causes the threaded seat 15 to slide, thereby pulling the piston 24 within the metering drum 5 via the push rod 14. At this time, the second solenoid valve 12 is closed, and the first solenoid valve 11 is open. The piston 24 then slides upward through the feed pipe 9 to draw raw materials from the storage box 4 and into the metering drum 5. Simultaneously, when the threaded seat 15 slides upward, the pressing rod 16 presses the button 23, at which point the first solenoid valve 11 closes, the second solenoid valve 12 opens, and the second motor 13 reverses direction. This causes the piston 24 to slide downward, pushing the material into the mixing drum 1 to participate in the mixing process, thus achieving precise metering of the cable material.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
