Description

Technical Field

[0001] This application relates to the field of flux processing technology, and more specifically, to a quantitative feeding device for flux processing. Background Technology

[0002] Flux is a chemical substance that helps and promotes the welding process in welding, while also providing protection and preventing oxidation reactions. Fluxes can be classified as solid, liquid, and gas, and their functions include removing oxides and reducing the surface tension of the materials being welded.

[0003] After searching, it was found that application number CN202220504895.2, entitled "A Quantitative Feeding Device for Lead-Free Flux Processing," addresses the problem that manual addition of raw materials is required during the production of lead-free flux. However, workers are prone to fatigue after repeated additions, affecting the efficiency of material addition. The device addresses this issue by using a rotating rod to drive a roller, which in turn drives an open receiving trough. When the receiving trough rotates to its lower end, an arc-shaped sealing block rotates downwards under the pressure of the raw material, causing the material to fall into the receiving trough through the notch. As the roller continues to rotate, it rotates the arc-shaped sealing block back, blocking the opening. When the roller drives the receiving trough downwards, the receiving trough drops the raw material into the discharge pipe and into the processing box for processing, thus avoiding the fatigue caused by repeated material additions by workers.

[0004] However, in actual use, since the volume of the receiving tank is fixed, it is impossible to adjust the amount of material fed each time when it is necessary to increase or decrease the amount of material fed each time, which is inconvenient to adjust. Further improvements can be made. At the same time, since the flux is mostly granular or powdered, the raw materials are prone to bridging and are difficult to fall stably into the receiving tank, affecting the stability of feeding. Further improvements can also be made.

[0005] To address the aforementioned problems, this application provides a quantitative feeding device for flux processing. Utility Model Content

[0006] The quantitative feeding device for flux processing provided in this application adopts the following technical solution:

[0007] A quantitative feeding device for flux processing includes a feeding tank and a base plate. The base plate is fixedly installed inside the feeding tank, and a stepper motor is fixedly installed on the bottom surface of the base plate. A shaft is installed at the output end of the stepper motor. An outer cylinder is fixedly connected to the outer wall of the shaft via a connecting rod, and the bottom surface of the outer cylinder slides against the top surface of the base plate. An inner cylinder is slidably inserted into the outer cylinder, and a circular plate is fixedly installed on the top surface of the inner cylinder. A lifting plate is slidably connected inside the feeding tank, and an annular groove is integrally connected to the bottom surface of the lifting plate. The edge of the circular plate is inserted into the annular groove and rotatably connected to the annular groove. A handle screw is rotatably connected to the top surface of the circular plate via a rotating connecting seat, and the handle screw passes through the top surface of the feeding tank and is threadedly connected to the feeding tank. A feed inlet is opened through the surface of the lifting plate, a discharge outlet is opened through the surface of the base plate, and a top opening is opened on the surface of the circular plate directly above the inner cylinder. A vibration motor is fixedly installed on the side wall of the feeding tank.

[0008] The above technical solution facilitates changing the feeding volume and allows for quantitative feeding.

[0009] Furthermore, the centers of the discharge port and the inlet are on the same circular cross-section as the center of the top opening, and the included angle between the discharge port and the inlet is 180°.

[0010] The above technical solution facilitates the feeding of raw materials into and out of the inner cylinder.

[0011] Furthermore, the outer cylinder and the inner cylinder are arranged in multiple sets at equal angles along the shaft, and the outer wall of the inner cylinder slides against the inner wall of the outer cylinder.

[0012] The above technical solution facilitates the lifting and adjustment of the inner cylinder, and makes it easy to change the internal volume of the inner and outer cylinders.

[0013] Furthermore, the top surface of the feeding tank is provided with a feeding port, which is located above the inlet.

[0014] The above technical solution makes it easier for staff to add raw materials.

[0015] Furthermore, the edge of the lifting plate slides against the inner wall of the feeding tank, and the bottom of the feeding tank has a funnel-shaped structure.

[0016] The above technical solution facilitates centralized material discharge.

[0017] Furthermore, a guide rod is vertically fixedly installed on the top surface of the lifting plate, and the guide rod passes through the top surface of the feeding tank and is slidably connected to the top surface of the feeding tank.

[0018] The above technical solutions facilitate the improvement of the stability of the lifting platform.

[0019] Furthermore, the stepper motor, shaft, circular plate, annular groove, lifting plate, and feeding tank are arranged coaxially, and the stepping angle of the stepper motor is equal to the included angle of the outer cylinder.

[0020] The above technical solutions facilitate the improvement of rotational stability.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] A stepper motor drives the outer and inner cylinders to rotate for quantitative feeding. During flux processing, the flux raw material is placed in the internal space of the feeding tank above the lifting plate. The flux enters one of the inner cylinders through the inlet and top hole. At this time, the opening at the bottom of the inner cylinder is closed by the bottom plate. The flux fills the inner cylinder under the vibration of the vibrating motor. Then, the stepper motor drives the shaft to rotate, which drives the outer and inner cylinders to rotate through the connecting rod until the inner cylinder filled with raw material rotates to align with the outlet. The raw material in the inner cylinder flows out of the feeding tank through the outlet, completing the quantitative feeding. The operator can turn the handle screw to drive the lifting plate to rise and fall, thereby moving the inner cylinder upward, thus changing the volume of the inner and outer cylinders, and thus changing the volume of each quantitative feeding. This facilitates adjustment and improves the convenience and flexibility of use, as well as work efficiency.

[0023] The high-frequency vibration of the vibrating motor drives the high-frequency vibration of the outer wall of the feeding tank. Through the vibration transmission effect, the raw materials are dispersed by vibration, avoiding the bridging effect, improving the efficiency of the raw materials passing through the feed inlet, thereby improving the stability of feeding and improving work efficiency.

[0033] Example:

[0034] This application discloses a quantitative feeding device for flux processing. Please refer to [link to relevant documentation]. Figure 1 and Figure 4The system includes a feeding tank 1 and a base plate 11. The base plate 11 is fixedly installed inside the feeding tank 1, and a stepper motor 17 is fixedly installed on the bottom surface of the base plate 11. A shaft 12 is installed at the output end of the stepper motor 17, which is a common drive structure. An outer cylinder 13 is fixedly connected to the outer wall of the shaft 12 through a connecting rod 16, and the bottom surface of the outer cylinder 13 slides against the top surface of the base plate 11 to prevent material leakage. An inner cylinder 14 is slidably inserted into the outer cylinder 13, and a circular plate 4 is fixedly installed on the top surface of the inner cylinder 14. The feeding tank 1 slides inside the inner cylinder 1. A lifting plate 2 is connected, and an annular groove 3 is integrally connected to the bottom surface of the lifting plate 2. The edge of the circular plate 4 is inserted into the annular groove 3 and rotatedly connected to the annular groove 3, which facilitates the up and down movement of the circular plate 4 with the annular groove 3 without affecting the rotation of the circular plate 4. The top surface of the circular plate 4 is rotatably connected to a handle screw 9 through a rotating connecting seat, and the handle screw 9 passes through the top surface of the feeding tank 1 and is threadedly connected to the feeding tank 1. A feed inlet 6 is provided through the surface of the lifting plate 2, and a discharge outlet 15 is provided through the surface of the bottom plate 11. The surface of the circular plate 4 is... A top opening 5 is provided directly above the inner cylinder 14. A vibration motor 7 is fixedly installed on the side wall of the feeding tank 1. During the flux processing, the flux raw material is placed in the internal space of the feeding tank 1 above the lifting plate 2. The flux enters one of the inner cylinders 14 through the inlet 6 and the top opening. At this time, the opening below the inner cylinder 14 is closed by the bottom plate 11. The flux fills the inner cylinder 14 under the vibration of the vibration motor 7. Subsequently, the stepper motor 17 drives the shaft 12 to rotate, which drives the connecting rod 16 to rotate the shaft 12. The outer cylinder 13 and the inner cylinder 14 rotate until the inner cylinder 14, filled with raw materials, rotates to align with the discharge port 15. The raw materials in the inner cylinder 14 then flow out of the feeding tank 1 through the discharge port 15, completing the quantitative feeding. The operator can rotate the handle screw 9 to drive the lifting plate 2 to rise and fall, thereby moving the inner cylinder 14 upward, thus changing the volume of the inner cylinder 14 and the outer cylinder 13, and thus changing the volume of each quantitative feeding. This facilitates adjustment and improves the convenience and flexibility of use, thereby increasing work efficiency.

[0035] Please see Figure 2 and Figure 3 The centers of the discharge port 15 and the feed port 6 are on the same circular cross section as the center of the top opening 5, and the included angle between the discharge port 15 and the feed port 6 is 180°. The top surface of the circular plate 4 blocks the feed port 6 during rotation to prevent raw materials from leaking to the outside of the outer cylinder 13.

[0036] Please see Figure 2 and Figure 3 Multiple sets of outer cylinder 13 and inner cylinder 14 are arranged at equal angles along shaft 12, and the outer wall of inner cylinder 14 slides against the inner wall of outer cylinder 13 to improve sliding stability.

[0037] Please see Figure 1 and Figure 4The top surface of the feeding tank 1 is provided with a feeding port 8, which is located above the inlet 6, so that the material can be piled up close to the inlet 6 when it is added, and the material can pass through the inlet 6.

[0038] Please see Figure 2 and Figure 3 The edge of the lifting plate 2 slides against the inner wall of the feeding tank 1, and the bottom of the feeding tank 1 has a funnel-shaped structure, which facilitates the centralized feeding of materials flowing out from the discharge port 15.

[0039] Please see Figure 2 and Figure 3 A guide rod 10 is vertically fixed on the top surface of the lifting plate 2, and the guide rod 10 passes through the top surface of the feeding tank 1 and is slidably connected to the top surface of the feeding tank 1. The guide rod 10 serves as a guide for the lifting of the lifting plate 2, thereby improving the stability of the movement of the lifting plate 2.

[0040] Please see Figure 2 and Figure 3 The stepper motor 17, shaft 12, circular plate 4, annular groove 3, lifting plate 2 and feeding tank 1 are arranged coaxially, and the stepping angle of the stepper motor 17 is equal to the included angle of the outer cylinder 13, which facilitates positioning and rotation.

[0041] The implementation principle of this embodiment is as follows: During use, in the flux processing process, the flux raw material is placed in the internal space of the feeding tank 1 above the lifting plate 2. The flux enters one of the inner cylinders 14 through the inlet 6 and the top hole. At this time, the opening below the inner cylinder 14 is closed by the bottom plate 11. The flux fills the inner cylinder 14 under the vibration of the vibration motor 7. Subsequently, the stepper motor 17 drives the shaft 12 to rotate, which drives the outer cylinder 13 and the inner cylinder 14 to rotate through the connecting rod 16 until the inner cylinder 14 filled with raw material rotates to be aligned with the outlet 15. Then, the raw material in the inner cylinder 14 flows out through the outlet 15. Feeding tank 1 completes quantitative feeding. The operator can rotate the handle screw 9 to drive the lifting plate 2 to rise and fall, thereby moving the inner cylinder 14 upward, thus changing the volume of the inner cylinder 14 and the outer cylinder 13, and thus changing the volume of each quantitative feeding. This facilitates adjustment and improves the convenience and flexibility of feeding, thereby increasing work efficiency. At the same time, the high-frequency vibration of the vibration motor 7 drives the outer wall of the feeding tank 1 to vibrate at high frequency. Through the vibration transmission effect, the raw materials are dispersed by vibration, avoiding the bridging effect and improving the efficiency of the raw materials passing through the feed inlet 6, thereby improving the stability of feeding and increasing work efficiency.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
