Description

Technical Field

[0001] This utility model relates to the technical field of quantitative feeding devices, and more specifically, to a quantitative feeding device for the production of barium-zinc stabilizers. Background Technology

[0002] The quantitative feeding device for zinc stabilizer production is a device specifically designed to control the amount of raw materials added during the zinc stabilizer production process.

[0003] In existing technologies, such as the document with publication number CN222586426U, a feeding device for the production of calcium-zinc stabilizers is disclosed. In this device, a metering wheel is rotated by a third motor to feed hydrotalcite into the groove of the metering wheel through the feeding port. When the groove containing hydrotalcite rotates to the notch at the bottom of the shell, the hydrotalcite is discharged from the notch at the bottom of the shell under its own gravity and enters the mixing box to mix with the stabilizer. However, in the production process, we found that some raw materials would adhere to the groove of the metering wheel during the feeding process, resulting in a large deviation in the feeding amount. Utility Model Content

[0004] This invention proposes a quantitative feeding device for the production of barium-zinc stabilizers, which ensures that the raw materials in the quantitative tank are completely discharged each time, thus solving the problem of feeding deviation caused by residue.

[0005] The technical solution of this utility model is as follows: a quantitative feeding device for the production of barium-zinc stabilizer, comprising an installation sleeve, a rotating sleeve rotatably connected to the inner wall of the installation sleeve, a plurality of quantitative grooves formed on the outer peripheral wall of the rotating sleeve, a sealing cap fixedly connected to the end of the installation sleeve, a support plate fixedly connected to the side of the sealing cap facing the rotating sleeve, a driving assembly installed on the inner wall of the installation sleeve, a sliding rod slidably connected to the inner wall of the support plate, an impact ball fixedly connected to the bottom of the sliding rod, a spring sleeved on the outer wall of the sliding rod, a limit ring fixedly connected to the outer wall of the sliding rod, and a protruding tooth fixedly connected to the outer wall of the sliding rod. The driving assembly is used to drive the protruding tooth to move.

[0006] Furthermore, one end of the spring is fixedly connected to the support plate, and the other end of the spring is fixedly connected to the impact ball.

[0007] Furthermore, the drive assembly includes an output shaft, one end of which is rotatably connected to a mounting sleeve, and the other end of which is rotatably connected to a sealing cover.

[0008] Furthermore, a shaft bracket is fixedly connected to the outer wall of the output shaft, the end of the shaft bracket is fixedly connected to the rotating sleeve, and a dial wheel is fixedly connected to the outer wall of the output shaft. When the dial wheel rotates, it drives the convex tooth to move.

[0009] Furthermore, the drive assembly also includes a stepper motor, the output end of which is fixedly connected to the output shaft.

[0010] Furthermore, a feed inlet is fixedly connected to the top of the mounting sleeve, and a discharge outlet is fixedly connected to the bottom of the mounting sleeve.

[0011] Furthermore, the outer walls at both ends of the rotating sleeve protrude outward to form annular flanges, which are rotatably connected to the inner wall of the mounting sleeve.

[0012] Furthermore, the inner wall of the mounting sleeve is provided with two sealing rings, which slide in contact with the annular groove on the outer peripheral wall of the rotating sleeve, forming a seal between the sealing rings and the rotating sleeve.

[0013] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0014] 1. The drive assembly drives the actuating wheel to periodically push the slide bar, causing the impact ball to strike the rotating sleeve under the action of the spring. The vibration generated by the impact can effectively remove the raw material attached to the metering tank, ensuring that the raw material in the metering tank is completely discharged each time it is fed, thus solving the problem of feeding deviation caused by residue.

[0015] 2. The sealing ring and the groove of the rotating sleeve slide to seal, preventing raw materials from leaking from the gap between the rotating sleeve and the mounting sleeve, thus avoiding raw material waste and equipment contamination. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] like Figures 1-4 As shown, a quantitative feeding device for the production of barium-zinc stabilizer includes an installation sleeve 1, a rotating sleeve 7 rotatably connected to the inner wall of the installation sleeve 1, a plurality of quantitative grooves 10 opened on the outer peripheral wall of the rotating sleeve 7, a sealing cover 2 fixedly connected to the end of the installation sleeve 1, a support plate 12 fixedly connected to the side of the sealing cover 2 facing the rotating sleeve 7, a driving assembly installed on the inner wall of the installation sleeve 1, a slide rod 13 slidably connected to the inner wall of the support plate 12, an impact ball 16 fixedly connected to the bottom of the slide rod 13, a spring 15 sleeved on the outer wall of the slide rod 13, a limit ring 14 fixedly connected to the outer wall of the slide rod 13, and a protruding tooth 18 fixedly connected to the outer wall of the slide rod 13. The driving assembly is used to drive the protruding tooth 18 to move. One end of the spring 15 is fixedly connected to the support plate 12, and the other end of the spring 15 is fixedly connected to the impact ball 16.

[0024] The metering groove 10 of the rotating sleeve 7 enables the metering of raw materials, and the drive component drives it to rotate to complete the feeding.

[0025] The impact ball 16 periodically impacts the rotating sleeve 7 under the action of the spring 15 and the drive assembly, and removes the raw material attached to the metering tank 10 through vibration, thus solving the problem of feed deviation caused by raw material residue in traditional devices.

[0026] like Figure 1 and Figure 2 As shown, the drive assembly includes an output shaft 6, one end of which is rotatably connected to the mounting sleeve 1, and the other end is rotatably connected to the sealing cover 2. A shaft bracket 11 is fixedly connected to the outer wall of the output shaft 6, and the end of the shaft bracket 11 is fixedly connected to the rotating sleeve 7. A dial wheel 17 is fixedly connected to the outer wall of the output shaft 6. When the dial wheel 17 rotates, it drives the tooth 18 to move. The drive assembly also includes a stepper motor 5, the output end of which is fixedly connected to the output shaft 6. A feed port 3 is fixedly connected to the top of the mounting sleeve 1, and a discharge port 4 is fixedly connected to the bottom of the mounting sleeve 1.

[0027] The output shaft 6 synchronously drives the rotating sleeve 7 and the actuating wheel 17 through the shaft bracket 11, ensuring that the feeding action of the rotating sleeve 7 and the cleaning action of the impact ball 16 are coordinated, avoiding untimely cleaning caused by the misalignment of their rhythms.

[0028] The control of stepper motor 5 and the angle of rotation of stepper motor 5 are control methods that are already disclosed in the prior art, and will not be elaborated on here.

[0029] like Figure 2 and Figure 3 As shown, the outer walls at both ends of the rotating sleeve 7 protrude outward to form annular flanges 9, which are rotatably connected to the inner wall of the mounting sleeve 1.

[0030] The flange 9 increases the contact area between the rotating sleeve 7 and the mounting sleeve 1, improves the stability of the rotating sleeve 7 when it rotates, prevents the quantitative groove 10 from being misaligned with the feed port 3 and the discharge port 4 due to radial shaking, and ensures the consistency of the feeding amount.

[0031] The annular flange structure reduces the friction area between the rotating sleeve 7 and the mounting sleeve 1, thus reducing wear.

[0032] like Figure 2 As shown, two sealing rings 8 are embedded in the inner wall of the mounting sleeve 1. The sealing rings 8 slide in contact with the annular groove on the outer peripheral wall of the rotating sleeve 7, and a seal is formed between the sealing rings 8 and the rotating sleeve 7.

[0033] The sealing ring 8 and the groove of the rotating sleeve 7 form a sliding seal to prevent raw materials from leaking from the gap between the rotating sleeve 7 and the mounting sleeve 1, thus avoiding material waste and equipment contamination.

[0034] Working principle: The raw material enters the mounting sleeve 1 from the feed port 3 and falls into the metering groove 10 of the rotating sleeve 7.

[0035] The stepper motor 5 of the drive component drives the output shaft 6 to rotate, and the shaft frame 11 synchronously drives the rotating sleeve 7 to rotate inside the mounting sleeve 1. When the quantitative trough 10 rotates with the rotating sleeve 7 to the discharge port 4, the raw material in the trough is discharged under the action of gravity, thus realizing quantitative feeding.

[0036] While the rotating sleeve 7 is rotating, the actuating wheel 17 on the output shaft 6 rotates synchronously. When the actuating wheel 17 contacts the tooth 18 on the slide bar 13, it pushes the slide bar 13 to slide upward along the support plate 12 and compresses the spring 15.

[0037] When the actuating wheel 17 disengages from the tooth 18, the spring 15 resets and pushes the slide bar 13 downward, causing the impact ball 16 at the bottom to strike the outer wall of the rotating sleeve 7. The vibration generated by the impact causes the raw material attached to the metering tank 10 to fall off, ensuring that the raw material is completely discharged.

[0038] The sealing ring 8 and the flange 9 of the rotating sleeve 7 cooperate to ensure the internal sealing of the mounting sleeve 1 and prevent raw material leakage. The rotation accuracy of the rotating sleeve 7 is guaranteed by the cooperation between the mounting sleeve 1 and the flange 9, ensuring that the quantitative groove 10 is precisely connected with the feed inlet 3 and the discharge outlet 4, thereby improving the accuracy of the feeding amount.

[0039] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
