Description

Technical Field

[0001] This invention relates to a process for processing enameled wire, and more particularly to a process and apparatus for treating copper wire for enameled wire. Background Technology

[0002] In the production process of enameled wire, the copper wire needs to be drawn by a drawing machine, and its surface is lubricated with drawing oil during the drawing process. This results in a certain amount of copper powder and drawing oil adhering to the surface of the copper wire after drawing. In order to prevent the copper powder and drawing oil from hindering the subsequent coating process, manufacturers now clean the copper wire before it enters the enameling machine.

[0003] Based on the above, existing methods for cleaning copper wires involve wiping the surface of the copper wire with felt. This involves passing the copper wire horizontally between two layers of felt, with the felt layers adhering to the wire under pressure, causing copper powder and drawing oil on the wire's surface to adhere to the felt layers. However, this structure has a drawback: after prolonged use, a large amount of copper powder and drawing oil accumulates on the felt at the contact points with the copper wire. This makes it impossible to remove the copper powder and drawing oil during subsequent use, and it also causes even more copper powder and drawing oil to adhere to the copper wire. Its cleaning stability is relatively poor, and it requires frequent replacement of the felt by operators.

[0004] Therefore, there is a need for a treatment device that can improve the cleaning effect on copper wires. Summary of the Invention

[0005] The purpose of this invention is to provide a copper wire treatment process for enameled wire. This process improves the cleaning effect on the copper wire; it also provides a treatment apparatus capable of circulating and filtering the cleaning solution and automatically replacing the filter membrane.

[0006] The technical solution of this invention: a copper wire processing technology for enameled wire, comprising the following steps: ① The copper wire is drawn into wires, and the surface of the copper wire is lubricated with drawing oil during the drawing process to obtain copper wire A; ②The surface of copper wire A is sprayed with cleaning solution to remove copper powder and drawing oil adhering to the surface of copper wire A, thereby obtaining copper wire B; ③ Anneal the B copper wire to obtain the finished copper wire; In step ②, the cleaning solution is filtered by a filtration mechanism after spraying, and the filtered cleaning solution is re-sprayed onto the copper wire surface by a circulating spraying mechanism.

[0007] The processing apparatus used in the aforementioned copper wire processing technology for enameled wire includes a cleaning chamber. A wire routing channel for copper wires to pass through is formed in the middle of the cleaning chamber. A circulating spray mechanism is provided above the wire routing channel, and a filtration mechanism located inside the cleaning chamber is provided below the wire routing channel. A water collection tank is formed in the cleaning chamber below the filtration mechanism, and one side of the water collection tank is connected to the circulating spray mechanism via a return water pipe. The filtration mechanism includes a filter membrane layer. One end of the filter membrane layer extends horizontally to the outside of the cleaning chamber and is connected to a membrane exit roller. A tensioning mechanism is connected to the outside of the membrane exit roller, and the other end of the filter membrane layer extends to the outside of the cleaning chamber and is connected to a membrane drawing mechanism. The film extraction mechanism is used to extract the filter membrane layer on the film output roller; The film-dispensing roller is used to rotate and dispense film as the film-drawing mechanism draws it out; The tensioning mechanism is used to apply a torque to the film exit roller opposite to the direction of film exit rotation, so as to keep the filter membrane layer in a taut state.

[0008] In the aforementioned processing device, a guide roller is provided between the cleaning chamber and the film exit roller. Both ends of the guide roller and the film exit roller are rotatably connected to mounting frames, and the guide roller and the film exit roller are staggered vertically along the height direction.

[0009] In the aforementioned processing device, the film-drawing mechanism includes two film-drawing rollers distributed vertically. The two film-drawing rollers are respectively attached to the upper and lower surfaces of the filter membrane layer. The two film-drawing rollers are connected to each other by gears, and a drive motor is externally connected to one of the film-drawing rollers.

[0010] In the aforementioned processing device, the tensioning mechanism includes a friction sleeve rotatably connected to the film exit roller, a counterweight frame connected to the outside of the friction sleeve, a counterweight block connected to the counterweight frame, and a limiting block fixedly connected to the mounting frame on one side of the counterweight frame. The limiting block is used to limit the rotation of the counterweight frame.

[0011] In the aforementioned processing device, there are two friction sleeves, which are respectively arranged on the left and right sides of the filter membrane layer. Each friction sleeve is connected to a counterweight frame on its outer side. The two counterweight frames are connected to each other by a connecting rod. The counterweight is detachably connected to the connecting rod.

[0012] In the aforementioned processing device, the friction sleeve includes two clamping blocks when separated. The two clamping blocks are connected to each other by bolts on both sides. An arc-shaped friction surface is formed in the middle of each clamping block. The friction surface and the film output roller are in close contact with each other, and a gap is left between the two clamping blocks.

[0013] In the aforementioned processing device, the circulating spray mechanism includes multiple spray pipes spaced apart above the wire routing channel along the direction of the copper wire routing. Each spray pipe has multiple nozzles spaced apart at its bottom. One end of each spray pipe is connected to the others via a water distribution pipe, and the outside of the water distribution pipe is connected to a return water pipe via a circulating pump.

[0014] In the aforementioned processing device, the cleaning chamber is provided with guide rods on both the front and rear sides along the copper wire routing direction, and several guide wheels that cooperate with the copper wire are rotatably connected to the guide rods.

[0015] Compared with the prior art, the present invention has the following characteristics: (1) The present invention sprays the surface of the copper wire before annealing, so that the cleaning liquid can remove the copper powder and drawing oil adhering to the surface of the copper wire after spraying, thereby improving the subsequent coating effect of the copper wire; by circulating and filtering the cleaning liquid and spraying it, the cleaning effect of the cleaning liquid can be effectively guaranteed during the recycling process, and the accumulation of copper powder and drawing oil in the cleaning liquid can be avoided, thus affecting its cleaning stability. (2) Based on the above, by limiting the structure of the processing device, when the copper powder and drawing oil on the surface of the filter membrane layer accumulate excessively and affect its filtration effect and permeability, the membrane extraction mechanism can extract the filter membrane layer wound on the membrane exit roller, thereby realizing the automatic replacement of the filter membrane layer. (3) By limiting the structure of the tensioning mechanism, after the filter membrane layer is extracted, the counterweight frame can apply a torque opposite to the direction of rotation of the membrane roller, so that the membrane roller rotates in the opposite direction under the action of the torque and tensions the filter membrane layer, thereby effectively avoiding the excessive extension, drooping or flipping of the filter membrane layer caused by the rotational inertia of the membrane roller or the gravity of the cleaning liquid, thus ensuring the filtration stability of the filter membrane layer. (4) By limiting the connection structure of the friction sleeve, the operator can also adjust the friction between the friction sleeve and the film discharge roller by bolts, so that the film discharge roller can stably drive the friction sleeve to rotate when rotating to discharge material, and form relative rotation with the friction sleeve after the friction sleeve rotates to the position, thereby ensuring the film discharge stability of the film discharge roller. Therefore, the present invention can improve the cleaning effect on copper wires and realize the circulation filtration of cleaning solution and automatic replacement of filter membrane.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0019] Example 1. The copper wire processing technology for enameled wire includes the following steps: ① The copper wire is drawn into wires, and the surface of the copper wire is lubricated with drawing oil during the drawing process to obtain copper wire A; ② The surface of copper wire A is sprayed with a cleaning solution, specifically deionized water, to remove copper powder and drawing oil adhering to the surface of copper wire A, thereby obtaining copper wire B; ③ Anneal the B copper wire to obtain the finished copper wire; In step ②, the cleaning solution is filtered by a filtration mechanism after spraying, and the filtered cleaning solution is re-sprayed onto the surface of the copper wire by a circulating spraying mechanism.

[0020] This embodiment sprays a cleaning solution onto the surface of the drawn copper wire, washing away copper powder and drawing oil adhering to the surface, thereby improving the subsequent coating effect. Filtering and circulating the cleaning solution ensures its cleanliness during reuse, preventing copper powder and drawing oil from contaminating the solution and reducing its cleaning effectiveness.

[0021] Example 2. Processing apparatus, configured as follows Figure 1 As shown, the processing device is used to spray copper wire A in Example 1 to remove copper powder and drawing oil adhering to the surface of copper wire A, and to filter the cleaning solution after spraying, thereby realizing the function of circulating spraying of cleaning solution. The processing device includes a cleaning chamber 1, with a wiring channel formed in the middle of the cleaning chamber 1 for copper wires to pass through. A circulating spray mechanism is provided above the wiring channel, and a filter mechanism is provided below the wiring channel inside the cleaning chamber 1. A water collection tank 2 is formed below the filter mechanism in the cleaning chamber 1, and one side of the water collection tank 2 is connected to the circulating spray mechanism via a return water pipe. The filter mechanism includes a filter membrane layer 3, which can be a water-permeable and oil-repellent PTFE membrane. One end of the filter membrane layer 3 extends horizontally to the outside of the cleaning chamber 1 and is wound on a membrane cylinder. The membrane cylinder is sleeved on the membrane exit roller 4 and fixedly connected to the membrane exit roller 4. A tensioning mechanism is connected to the outside of the membrane exit roller 4. The other end of the filter membrane layer 3 extends to the outside of the cleaning chamber 1 and is connected to a membrane drawing mechanism. The film extraction mechanism is used to extract the filter membrane layer 3 on the film output roller 4; The film-exiting roller 4 is used to rotate and expel film as the film-drawing mechanism draws it out; The tensioning mechanism is used to apply a torque to the film exit roller 4 opposite to the direction of film exit rotation, so as to keep the filter membrane layer 3 in a taut state.

[0022] The two side walls of the cleaning chamber 1 are provided with support plates located on the filter membrane layer 3. The support plates are used to support the two side edges of the filter membrane layer 3.

[0023] A guide roller 5 is provided between the cleaning chamber 1 and the film exit roller 4. Both ends of the guide roller 5 and the film exit roller 4 are rotatably connected to the mounting frame 6. The guide roller 5 and the film exit roller 4 are staggered vertically along the height direction. After the filter membrane layer 3 extends out from the film exit roller 4, it passes through the guide roller 5 and enters the cleaning chamber 1. Thus, the guide roller 5 and the film drawing mechanism limit the height of the filter membrane layer 3 from both sides of the cleaning chamber 1, so that the filter membrane layer 3 remains horizontal in the cleaning chamber 1.

[0024] The guide roller 5 is externally connected to an encoder. The guide roller 5 can detect the number of rotations of the guide roller 5 each time the membrane is discharged, thereby controlling the replacement length of the filter membrane layer 3. Based on this, the manufacturer can replace the filter membrane layer 3 periodically by setting a preset replacement frequency, or manually control the replacement of the filter membrane layer 3 by observing the actual filtration status of the filter membrane layer 3.

[0025] The film-drawing mechanism includes two film-drawing rollers 7 arranged vertically. The two film-drawing rollers 7 are respectively attached to the upper and lower surfaces of the filter membrane layer 3. The two film-drawing rollers 7 are connected to each other by gears. One of the film-drawing rollers 7 is externally connected to a drive motor. When working, the two film-drawing rollers 7 rotate in opposite directions to drive the filter membrane layer 3 in the cleaning chamber 1 to move towards the film-drawing rollers 7, thereby realizing the film-drawing function.

[0026] A collection box is located below the membrane extraction mechanism. After the filter membrane layer 3 is extracted, it naturally falls into the collection box, and the collection box is cleaned regularly by the operators.

[0027] The tensioning mechanism includes a friction sleeve 8 rotatably connected to the film exit roller 4, a counterweight frame 9 connected to the outside of the friction sleeve 8, a counterweight block 10 connected to the counterweight frame 9, and a limiting block 11 fixedly connected to the mounting frame 6 on one side of the counterweight frame 9. The limiting block 11 is used to limit the rotation of the counterweight frame 9 along the rotational film exit direction of the filter membrane layer 3.

[0028] There are two friction sleeves 8, which are respectively set on the left and right sides of the filter membrane layer 3. Each friction sleeve 8 is connected to a counterweight frame 9 on its outer side. The two counterweight frames 9 are connected to each other by a connecting rod 12. The counterweight block 10 is detachably connected to the connecting rod 12. The manufacturer can adjust the weight of the counterweight block 10 according to the actual tensioning effect, so that the counterweight frame 9 can drive the membrane roller 4 to rotate and tension under the action of gravity, without causing excessive elongation of the filter membrane layer 3.

[0029] The friction sleeve 8 includes two clamping blocks when separated. The two clamping blocks are connected to each other by bolts on both sides. An arc-shaped friction surface is formed in the middle of each clamping block. The friction surface and the film output roller 4 are in close contact with each other, and there is a gap between the two clamping blocks.

[0030] The counterweight frame 9 is arranged side by side on both sides of the friction sleeve 8. The two counterweight frames 9 and the friction sleeve 8 are connected to each other by counterweight bolts. One end of the counterweight frame 9 extends to the outside of the friction sleeve 8 and is detachably connected to the connecting rod 12.

[0031] The two ends of the connecting rod 12 pass through the counterweight frame 9 and are axially limited by the shaft retaining ring. The counterweight block 10 is sleeved on the connecting rod 12 and is axially limited on both sides by the limiting sleeve, thereby preventing the axial movement of the counterweight block 10.

[0032] The circulating spray mechanism includes multiple spray pipes 13 spaced apart above the wire routing channel along the direction of the copper wire routing. Each spray pipe 13 has multiple nozzles spaced apart at its bottom. One end of each spray pipe 13 is connected to the others via a water distribution pipe 14. The outside of the water distribution pipe 14 is connected to a return water pipe via a circulating pump.

[0033] The cleaning chamber 1 is provided with guide rods 15 on both the front and rear sides along the direction of the copper wire, and a number of guide wheels 16 that cooperate with the copper wire are rotatably connected to the guide rods 15.

[0034] In this embodiment, the copper wire passes horizontally through the cleaning chamber 1 under the guidance of the guide wheel 16, and the cleaning liquid is sprayed onto the surface of the copper wire by the spray pipe 13 above, thereby removing the copper powder and drawing oil adhering to the surface of the copper wire. After spraying, the cleaning liquid, along with the copper powder and drawing oil, falls onto the filter membrane layer 3. The cleaning liquid passes through the filter membrane layer 3 and falls into the water collection tank 2 below, while the copper powder and drawing oil are intercepted by the filter membrane layer 3, thereby achieving the filtration function of the cleaning liquid.

[0035] When the filter membrane layer 3 needs to be replaced, the extraction roller 7 extracts the filter membrane layer 3 by rotating, while the exit roller 4 rotates clockwise as the filter membrane layer 3 is extracted, thus achieving the membrane exit function. During the membrane exit roller 4's rotation, the friction sleeve 8 rotates synchronously with the exit roller 4 under frictional force until the counterweight 9 contacts the limiting block 11. Then, the exit roller 4 continues to rotate as the filter membrane layer 3 is extracted, while the friction sleeve 8 remains in its current position due to the obstruction of the limiting block 11, applying a counterclockwise torque to the exit roller 4. When the extraction roller 7 stops rotating, the exit roller 4 rotates counterclockwise under the torque of the friction sleeve 8 until the filter membrane layer 3 is completely flattened, thus achieving tensioning of the filter membrane layer 3. This coordination ensures that the filter membrane layer 3 remains continuously tensioned during operation, preventing sagging caused by the accumulation of cleaning liquid on its surface, thereby improving the filtration effect on the cleaning liquid.
