Description

Technical Field

[0001] This utility model relates to the field of automatic alcohol dispensing, and more particularly to the field of pipe annealing and tin plating, specifically to an automatic alcohol dispensing mechanism for a pipe annealing and tin plating machine. Background Technology

[0002] Tin plating with annealed wire is a common metal surface treatment process with wide applications, including but not limited to machinery manufacturing, electronics, and automotive parts. In this process, the tin plating layer improves the corrosion resistance, conductivity, and weldability of the metal material. In the field of copper wire processing technology, tin plating with annealed wire is a crucial process. After copper wire is drawn, it must undergo annealing to eliminate internal stress, while tin plating enhances the copper wire's oxidation resistance and conductivity. During annealing and tin plating, the copper wire is easily oxidized upon contact with air due to the high temperature. Therefore, alcohol is added for anti-oxidation treatment. The addition of alcohol not only effectively prevents copper wire oxidation but also improves product quality and yield.

[0003] Currently, some automatic alcohol dispensing mechanisms exist on the market, primarily used in copper wire tube annealing and tin plating equipment. These mechanisms typically consist of an alcohol tank, alcohol dispensing pipeline, detection sensors, a controller, and a solenoid directional valve. The alcohol tank serves as a container for storing alcohol, supplying it to each annealing tube via the alcohol dispensing pipeline. The detection sensors monitor the operating status of the annealing tubes; when a tube begins operation, the sensor sends a signal to the controller. Upon receiving the signal, the controller opens the solenoid directional valve, allowing alcohol to flow from the alcohol tank and into the annealing tubes through the dispensing pipeline, thus achieving automatic alcohol dispensing.

[0004] The existing alcohol dispensing structure is as follows: Figure 1 As shown, it includes an alcohol nozzle sleeve a, a filling hole a1 opened on the alcohol nozzle sleeve, a connecting channel a2, a central hole a3, and a sleeve hole a4 for installing an annealing tube. Its existing connecting channel connects the filling hole and the central hole through inclined drilling, which facilitates the filling of alcohol. However, the filling of alcohol still has a reverse flow, and the inclined setting of the connecting channel has a relatively complex drilling process, which affects the use and production.

[0005] However, although existing automatic alcohol dispensing mechanisms have achieved automatic alcohol dispensing to a certain extent, some shortcomings still exist. The alcohol dispensing structure of some mechanisms is relatively simple, and alcohol tends to spray out in the opposite direction of the annealing tube when passing through the nozzle sleeve, resulting in either too much or too little alcohol. This not only affects the anti-oxidation effect but also wastes alcohol. Furthermore, due to the relatively simple channel design of existing alcohol dispensing systems, the dispensing stability is poor, which is not conducive to the effective prevention of oxidation of the copper wire, thus affecting the dispensing effect and usability of the alcohol. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned defects and provide an automatic alcohol dispensing mechanism for a pipeline annealing tin plating machine. This addresses the technical problem in the prior art where the channel setting of the existing nozzle sleeve is relatively simple, resulting in poor alcohol dispensing stability and easy oxidation of the copper wire, thus affecting the dispensing effect and use.

[0007] The objective of this utility model is achieved through the following means:

[0008] An automatic alcohol dispensing mechanism for a pipeline annealing tin plating machine includes a liquid storage tank and a gas storage tank. The gas storage tank is connected to the liquid storage tank via a gas supply pipeline. The liquid storage tank is connected to a nozzle assembly via an alcohol supply device. The nozzle assembly has a connecting end for connecting to the annealing tube of the annealing tin plating machine. The nozzle assembly includes a connector for connecting to the alcohol supply device and an alcohol nozzle sleeve. The alcohol nozzle sleeve has an installation hole for connecting to the annealing tube inside. The installation hole is located at one end of the alcohol nozzle sleeve, and the other end of the alcohol nozzle sleeve has a through hole communicating with the installation hole. The alcohol nozzle sleeve has a connecting hole, and one end of the connector is connected to the connecting hole of the alcohol nozzle sleeve via a thread. The alcohol nozzle sleeve has a dispensing channel inside that communicates with the installation hole and the connecting hole. One end of the dispensing channel extends toward the installation hole and is arranged parallel to the axial extension direction of the installation hole.

[0009] Furthermore, as described above, the annealing tube is coaxially connected to the mounting hole, and the annealing tube is made of a hollow tube. A limiting hole communicating with the mounting hole is provided on the outer side of the alcohol nozzle sleeve.

[0010] The mounting hole is used to connect the annealing tube of the tin plating machine. The connection hole and the mounting hole can be connected through the filling channel, so that alcohol can be added to the filling channel. The alcohol then flows through the filling channel to the annealing tube on the mounting hole, thus completing the filling and use of alcohol.

[0011] Furthermore, as described above, the other end of the filling channel extends toward the connecting hole and is connected to it, and the axial extension direction of the filling channel is parallel to the axial extension direction of the mounting hole.

[0012] The filling channel is connected to the connecting hole and is parallel to the axis of the mounting hole, so that the alcohol flows directly to the mounting hole after passing through the connecting hole into the filling channel.

[0013] Specifically, the end of the filling channel near the connection hole is the sealing end, and the end of the filling channel near the mounting hole is the conducting end, so that the alcohol can be directly discharged from the filling channel to the mounting hole, preventing the alcohol from flowing out in the opposite direction, improving the stability and reliability of alcohol filling, and enhancing the anti-oxidation treatment effect of the copper wire.

[0014] Furthermore, as described above, the inner diameter of the mounting hole is larger than the diameter of the filling channel and the through hole, and the outer surface of the alcohol nozzle sleeve is provided with a threaded hole that communicates with the through hole.

[0015] Specifically, the inner diameter of the mounting hole can enclose the filling channel and through hole, allowing alcohol to easily enter the annealing tube inside the mounting hole through the filling channel, thereby improving alcohol flow efficiency and ensuring stable filling and use.

[0016] Further, as described above, the alcohol supply device includes a separating pipe, an inlet pipe, and an outlet pipe for connection with a connector. The separating pipe is equipped with an inlet valve that connects to the inlet pipe, and the separating pipe has a conductive separating channel inside. One end of the inlet pipe is connected to the inlet valve, and the other end of the inlet pipe is connected to the drain end of the storage tank. One end of the outlet pipe is connected to the separating pipe, and the other end of the outlet pipe is connected to the connector.

[0017] The liquid distribution pipe allows the alcohol in the storage tank to be evenly discharged through the outlet pipe, thus enabling the use of multiple annealing tubes.

[0018] Furthermore, as described above, there are several outlet pipes, and each outlet pipe is connected to a nozzle assembly at one end.

[0019] Furthermore, as described above, the gas supply pipeline is connected to a pressure regulating valve for controlling the pressure of the gas source discharged from the gas storage tank.

[0020] Furthermore, as described above, the top of the storage tank is also provided with an exhaust port and an alcohol addition port, each equipped with a corresponding valve, thereby facilitating the venting and alcohol addition.

[0021] The beneficial effects of this utility model are as follows: The connector is connected to the alcohol nozzle sleeve via a thread. The mounting hole inside the alcohol nozzle sleeve is used to connect to the annealing tube of the annealing and tin plating machine, allowing alcohol to smoothly enter the annealing tube. One end of the filling channel extends towards the mounting hole and is parallel to the axial extension direction of the mounting hole. The other end of the filling channel extends towards the connecting hole, ensuring that alcohol can smoothly flow from the storage tank through the alcohol supply device, connector, and filling channel to the annealing tube. The parallel arrangement of the filling channel and the mounting hole allows the alcohol sprayed from the connector to enter the annealing tube more evenly and stably through the connecting hole and filling channel, improving the smoothness and efficiency of alcohol filling. At the same time, it reduces the reverse spraying of alcohol through the filling channel, improving the stability of alcohol spraying. Furthermore, the combination of the storage tank, gas storage pipe, and alcohol supply device enables automatic, uniform, and continuous alcohol filling, improving the anti-oxidation effect and ensuring product quality.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] In this embodiment, refer to Figures 2-6 The present invention relates to an automatic alcohol dispensing mechanism for a pipeline annealing tin plating machine, comprising a liquid storage tank 1 and a gas storage tank 2. The gas storage tank 2 is connected to the liquid storage tank 1 via a gas supply pipe 3. The liquid storage tank 1 is connected to a nozzle assembly 4 via an alcohol supply device. The nozzle assembly 4 has a connecting end for connecting to an annealing tube 5 of the annealing tin plating machine. The nozzle assembly 4 includes a connector 41 for connecting to the alcohol supply device and an alcohol nozzle sleeve 42. The alcohol nozzle sleeve 42 has an internal mounting hole 421 for connecting to the annealing tube 5. An alcohol nozzle sleeve 42 is provided at one end, and the other end of the alcohol nozzle sleeve 42 is provided with a through hole 422 communicating with the mounting hole 421. The alcohol nozzle sleeve 42 is provided with a connection hole 423. One end of the connector 41 is connected to the connection hole 423 of the alcohol nozzle sleeve 42 by a thread. The interior of the alcohol nozzle sleeve 42 is provided with a filling channel 424 communicating with the mounting hole 421 and the connection hole 423. One end of the filling channel 424 extends toward the mounting hole 421 and is arranged parallel to the axial extension direction of the mounting hole 421.

[0031] The annealing tube 5 is coaxially connected to the mounting hole 421, and the annealing tube 5 is made of a hollow tube. The outer side of the alcohol nozzle sleeve 42 has a limiting hole 425 that communicates with the mounting hole 421. The mounting hole 421 is used to connect the annealing tube 5 of the tin plating machine, so that the connecting hole 423 and the mounting hole 421 can be connected through the filling channel 424, so that the connector 41 can add alcohol to the filling channel 424, and the alcohol flows through the filling channel 424 to the annealing tube 5 on the mounting hole 421, thereby completing the filling and use of alcohol.

[0032] The other end of the filling channel 424 extends toward and is connected to the connecting hole 423. The axial extension direction of the filling channel 424 is parallel to the axial extension direction of the mounting hole 421. The connection between the filling channel 424 and the connecting hole 423 and its parallel axial direction to the mounting hole 421 allow alcohol to pass through the connecting hole 423 into the filling channel 424 and flow directly to the mounting hole 421.

[0033] Specifically, the end of the filling channel 424 near the connection hole 423 is a sealing end, and the end of the filling channel 424 near the mounting hole 421 is a conducting end, so that the alcohol can be directly discharged from the filling channel 424 to the mounting hole 421, preventing the alcohol from flowing out in the opposite direction, improving the stability and reliability of alcohol filling, and enhancing the anti-oxidation treatment effect of the copper wire.

[0034] The inner diameter of the mounting hole 421 is larger than the diameters of the filling channel 424 and the through hole 422. The outer surface of the alcohol nozzle sleeve 42 has a threaded hole 426 communicating with the through hole 422. Specifically, the inner diameter of the mounting hole 421 can enclose the filling channel 424 and the through hole 422, allowing alcohol to easily enter the annealing tube 5 within the mounting hole 421 through the filling channel 424, improving alcohol flow efficiency and ensuring stable filling. Specifically, a sealing element 11 is connected to the end of the through hole 422 furthest from the annealing tube 5.

[0035] The alcohol supply device includes a distributor pipe 6, an inlet pipe 7, and an outlet pipe 8 for connection to a connector 41. The distributor pipe 6 is equipped with an inlet valve 9 connected to the inlet pipe 7, and the distributor pipe 6 has an internal dispensing channel (not shown). One end of the inlet pipe 7 is connected to the inlet valve 9, and the other end is connected to the drain end of the storage tank 1. One end of the outlet pipe 8 is connected to the distributor pipe 6, and the other end is connected to the connector 41. Each outlet pipe 8 has a nozzle assembly 4 connected to one end. The distributor pipe 6 allows the alcohol in the storage tank 1 to be evenly discharged through the outlet pipe 8, thus enabling the use of multiple annealing tubes 5.

[0036] The gas supply pipe 3 is connected to a pressure regulating valve 10 for controlling the pressure of the gas source discharged from the gas storage tank 2. The top of the liquid storage tank 1 is also provided with an exhaust port (not shown) and an alcohol addition port (not shown), and the exhaust port and alcohol addition port are respectively provided with corresponding valves, so as to facilitate the exhaust and the addition of alcohol.

[0037] Specifically, it also includes solenoid directional valves, sensors, and controllers for controlling the on / off flow of each alcohol dispensing unit. The signal input terminal of the controller is connected to the sensor. The sensor is a Hall effect sensor, and the controller is a microcontroller. The controller controls the on / off state of the solenoid directional valves via relays.

[0038] Specifically, the principle of controlling the use of alcohol dispensing is a conventional technical means in this field, which is described in detail in publication number CN211005561 U. Therefore, it will not be specifically described in this utility model.

[0039] The specific operating principle in this embodiment is as follows:

[0040] The automatic alcohol dispensing mechanism is connected to the annealing and tin plating machine. The connector 41 is threaded to the alcohol nozzle sleeve 42 and connected to the outlet pipe 8. The mounting hole 421 inside the alcohol nozzle sleeve 42 is used to connect to the annealing pipe 5 of the annealing and tin plating machine, allowing the alcohol to smoothly enter the annealing pipe 5. By connecting to an external controller, the gas storage tank 2 is controlled to provide gas pressure to the liquid storage tank 1, so that the alcohol enters the liquid distribution channel of the liquid distribution pipe 6 through the liquid inlet pipe 7 under gas pressure, and is discharged to each alcohol nozzle sleeve 42 through the liquid outlet pipe 8. One end of the dispensing channel 424 extends into the mounting hole 421 and is set parallel to the axial extension direction of the mounting hole 421, while the other end of the dispensing channel 424 enters into the connection hole 423. The extended flow path ensures that alcohol can smoothly flow from the storage tank 1 through the alcohol supply device, connector 41, and filling channel 424 to the annealing tube 5. The parallel arrangement of the filling channel 424 and the mounting hole 421 allows the alcohol sprayed from the connector 41 to enter the annealing tube 5 more evenly and stably through the connecting hole 423 and the filling channel 424, improving the smoothness and efficiency of alcohol filling. At the same time, the sealing at the end of the filling channel 424 reduces the reverse spraying of alcohol through the filling channel 424, improving the stability of alcohol spraying. Furthermore, the arrangement of the storage tank 1, the gas storage pipe, and the alcohol supply device enables automatic, uniform, and continuous alcohol filling, improving the anti-oxidation effect and ensuring product quality.
