Description

Technical Field

[0001] This invention relates to the technical field of copper wire production, and specifically to an annealing and coating machine for producing soft copper wire. Background Technology

[0002] Soft copper wire is a conductor made of multiple strands of conductive solid metal wires with a diameter of less than 1 mm twisted together. Soft copper wire has strong fatigue resistance (resistance to transverse breakage). The wire needs to be bent frequently to produce corresponding curvature changes, so the fatigue resistance of the wire is very high.

[0003] Soft copper wire annealing is a process that involves heating and cooling to rearrange the grains inside the copper wire, correcting the tensile hardening and deformation caused by grain misalignment during processing. This improves the flexibility and ductility of the copper wire, reduces internal stress, and helps improve its conductivity and service life.

[0004] In existing production workshops, water cooling is mostly used when cooling copper wires. However, most cooling methods involve placing the wires in a cooling box. When a natural gas stove head plate horizontally heats multiple sets of soft copper wires, black slag is easily produced after the soft copper wires are burned. Annealing and painting machines lack a mechanism to clean and maintain the black slag on the surface of the copper wires, which affects the gloss of the soft copper wires and makes it inconvenient to quickly remove the black slag from the surface of the soft copper wires.

[0005] 2. At the same time, during the cleaning process of soft copper wires of different diameters, it is difficult for the cleaning mechanism itself to adjust the cleaning range and spacing according to the size and quantity of the wires, which affects the efficiency and quality of wire cleaning.

[0006] 3. Furthermore, during the copper wire painting process, the quality characteristics of various enameled wires are different, but the enameled wires themselves possess four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Existing painting machines lack auxiliary operations for drying the paint to improve the drying and processing efficiency of the wires. Summary of the Invention

[0007] The purpose of this invention is to provide an annealing and coating machine for producing soft copper wire, so as to solve the above-mentioned defects caused by the prior art.

[0008] An annealing and painting machine for producing soft copper wire includes a receiving roller, a paint dropper, and a liquid injection pump. An annealing shell is located on one side of the receiving roller, and an unfolding roller is located on the other side of the annealing shell. A cleaning mechanism is located inside the annealing shell to remove black slag and other deposits from the surface of the annealed wire, facilitating subsequent painting operations. A drying mechanism is located at one end of the outer side of the annealing shell to dry the paint sprayed onto the wire surface, shortening the paint drying time. A paint delivery pipe is located at the top of the annealing shell, and paint spray nozzles are evenly spaced at the bottom end of the paint delivery pipe. Natural gas burner plates are evenly distributed inside the annealing shell.

[0009] Preferably, the cleaning mechanism includes a cleaning plate, an adjusting spring, an adjusting screw, a locking nut, a ball screw, and two cleaning plates. The bottom end of the first cleaning plate has rectangularly distributed adjusting springs, and the bottom end of the first cleaning plate is provided with an adjusting screw. The bottom end of the adjusting screw is connected to the two cleaning plates. The outer side of the adjusting screw is threaded with a locking nut, and the middle part of the first cleaning plate is connected to a ball screw.

[0010] Preferably, both the cleaning plate and the bottom of the liquid storage tank are provided with leakage holes.

[0011] Preferably, the ball screw is connected to the output end of the servo motor via a fan blade disk connected to one side.

[0012] Preferably, the drying mechanism includes a drying chamber, an air supply duct, an aluminum heat-absorbing plate, a fan blade plate, and a threaded joint. A servo motor is installed on the outside of the drying chamber, and an aluminum heat-absorbing plate is installed inside the drying chamber. An annealing shell is connected through the aluminum heat-absorbing plate, and a fan blade plate is installed inside the aluminum heat-absorbing plate. A threaded joint is connected through the other side of the aluminum heat-absorbing plate, and the other side of the threaded joint is connected to the annealing shell. The other end of the air supply duct is connected through the annealing shell.

[0013] Preferably, the threaded joint is connected to one side of the annealing shell through an air supply duct connected to one side, and the air supply duct and the paint removal tray are parallel to each other.

[0014] Preferably, both the annealed shell and the outer side of the heat-insulating gypsum board are provided with outlet holes, and the other side of the annealed shell is provided with inlet holes.

[0015] Preferably, the paint removal tray is disposed inside the annealing shell, the width of the paint removal tray is smaller than the width of the annealing shell, and two sets of staggered guide rollers are provided on one side of the annealing shell.

[0016] Preferably, one end of the injection pump is located on the outside of the annealing shell, and the output end of the injection pump is connected to one end of the storage tank.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. When the gas stove head plate is heated and annealed with multiple sets of soft copper wires, the heat generated is absorbed by the aluminum heat-absorbing plate set on one side. At the same time, the fan blade plate accelerates the air flow speed and injects the heated air into the interior of the annealing shell to heat the annealed wire. The surface of the copper wire is evenly sprayed with varnish and the varnish on the surface of the copper wire is dried with high temperature air, which shortens the drying time of the varnish on the surface of the copper wire.

[0019] 2. Hold the locking nut on the adjusting screw and adjust the height of the locking nut. When the distance between the first and second cleaning plates is shortened, adjust the length of the adjusting spring and adjust the force used for cleaning the cotton. Precisely control the distance between the first and second cleaning plates according to the diameter of the wire to avoid excessive cleaning force, which would affect the efficiency of material cleaning. Then use the ball screw to drive the first and second cleaning plates to move laterally to clean multiple groups of copper wires.

[0020] 3. When the ball screw drives the first and second cleaning plates to move, the cotton blocks set at the bottom of the first and second cleaning plates are used to clean the copper wires. This makes it convenient to clean copper wires of different diameters, improves the efficiency of cleaning dirt from the surface of the copper wires, and cools and dries the surface of the copper wires, thus improving the efficiency of cleaning after annealing.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 1 to 8 As shown, an annealing and painting machine for producing soft copper wire includes a receiving roller 1, a paint dropper 15, and a liquid injection pump 16. An annealing shell 2 is provided on one side of the receiving roller 1, and an unfolding roller 6 is provided on the other side of the annealing shell 2. A cleaning mechanism 8 is provided inside the annealing shell 2 to clean the black slag and other attachments on the surface of the annealed wire, facilitating subsequent painting operations. A drying mechanism 9 is provided at one end of the outer side of the annealing shell 2 to dry the paint sprayed on the surface of the wire, shortening the paint drying time. A paint delivery pipe 3 is provided at the top of the annealing shell 2, and a paint spraying head 14 is provided at equal intervals at the bottom of the paint delivery pipe 3. Natural gas burner heads 7 are distributed at equal intervals inside the annealing shell 2.

[0033] In this embodiment, the cleaning mechanism 8 includes a cleaning plate 81, an adjusting spring 82, an adjusting screw 83, a locking nut 84, a ball screw 85, and two cleaning plates 86. The adjusting spring 82 is rectangularly distributed at the bottom end of the cleaning plate 81. The adjusting screw 83 is provided at the bottom end of the cleaning plate 81. The two cleaning plates 86 are connected through the bottom end of the adjusting screw 83. The locking nut 84 is threadedly connected to the outer side of the adjusting screw 83. The ball screw 85 is connected through the middle of the cleaning plate 81. The cleaning plate 81 is moved laterally by the ball screw 85, and the cleaning plate 81 is dynamically controlled.

[0034] In this embodiment, both the cleaning plate 81 and the liquid storage tank 12 have through-holes 87 at their bottom ends. Liquid is evenly introduced through the through-holes 87 to cool and clean the surface of the copper wire.

[0035] In this embodiment, the ball screw 85 is connected to the output end of the servo motor 4 via a fan blade disk 94 connected to one side. The servo motor 4 drives the ball screw 85 to rotate, and the ball screw 85 drives a cleaning plate 81 to move repeatedly to cool the wire.

[0036] In this embodiment, the drying mechanism 9 includes a drying chamber 91, an air supply duct 92, an aluminum heat-absorbing plate 93, a fan blade plate 94, and a threaded connector 95. A servo motor 4 is installed on the outside of the drying chamber 91. An aluminum heat-absorbing plate 93 is installed inside the drying chamber 91. An annealing shell 2 is connected through the aluminum heat-absorbing plate 93. A fan blade plate 94 is installed inside the aluminum heat-absorbing plate 93. A threaded connector 95 is connected through the other side of the aluminum heat-absorbing plate 93. An annealing shell is connected through the other end of the air supply duct 92. The aluminum heat-absorbing plate 93 absorbs heat and heats and circulates the air.

[0037] In this embodiment, the threaded connector 95 is connected to one side of the annealing shell 2 through an air supply pipe 92 connected to one side. The air supply pipe 92 and the paint removal tray 15 are parallel to each other. The heated air is circulated and introduced through the air supply pipe 92 to accelerate the drying speed of the paint.

[0038] In this embodiment, both the annealed shell 2 and the heat-insulating gypsum board 10 have through-holes 13 on their outer sides, and the other side of the annealed shell 2 has an inlet hole 5. Liquid is injected into the cotton block through the through-holes 13, and the cotton block is used to clean the copper wire.

[0039] In this embodiment, the paint removal tray 15 is disposed inside the annealing shell 2. The width of the paint removal tray 15 is smaller than the width of the annealing shell 2. Two sets of staggered guide rollers 11 are provided on one side of the annealing shell 2. The guide rollers 11 are used to guide the wire and prevent multiple sets of wires from tangling together.

[0040] In this embodiment, one end of the injection pump 16 is located on the outside of the annealing shell 2, and the output end of the injection pump 16 is connected to one end of the liquid storage tank 12. Cooling liquid is injected through the injection pump 16 to cool the surface of the wire.

[0041] In practical applications, this annealing and coating machine used for the production of soft copper wire includes the following tasks:

[0042] Step 1: The operator first fixes multiple sets of soft copper wires to the outside of the unfolding roller 6 in sequence, and then inserts the soft copper wires into the inlet holes 5 opened on the outside of the annealing shell 2 and the inlet holes 5 opened on the outside of the heat insulation gypsum board 10 in sequence. Then, the guide roller 11 set on one side guides the soft copper wires so that the soft copper wires and the paint spray head 14 are set parallel to each other. Then, the tail end of the soft copper wires is wound and connected to the outside of the collecting roller 1. The collecting roller 1 is used to wind and connect multiple sets of soft copper wires to collect the soft copper wires.

[0043] Step 2: The operator fixes the cleaning sponge or cotton into cotton blocks on the outside of the first cleaning plate 81 and the second cleaning plate 86 respectively, so that the cleaning cotton block on the first cleaning plate 81 is in contact with the soft copper wire. At the same time, the operator holds the locking nut 84 on the adjusting screw 83 and adjusts the height of the locking nut 84. When the distance between the first cleaning plate 81 and the second cleaning plate 86 is shortened, the length of the adjusting spring 82 is adjusted. The four sets of adjusting springs 82 are used to position the connection between the first cleaning plate 81 and the second cleaning plate 86, so that the cleaning cotton block at the bottom of the second cleaning plate 86 is in contact with the soft copper wire.

[0044] Step 3: At the same time, the injection pump 16 is connected to one end of the storage tank 12. After the soft copper wire is heated by the natural gas burner 7, the heated part is stretched and moved by the receiving roller 1 to the cleaning cotton block set on the first cleaning plate 81 and the second cleaning plate 86. The inside of the storage tank 12 contains internally added coolant and alum. The liquid is introduced into the cotton block through the leakage hole 87. The moisture inside the cotton block is used to repeatedly clean the heat and black slag on the surface of the copper wire.

[0045] Step 4: At this time, the receiving roller 1 is in a stationary state. Turn on the servo motor 4 and use the servo motor 4 to drive the ball screw 85 to rotate. Use the ball screw 85 to drive the first cleaning plate 81 and the second cleaning plate 86 to move laterally. During the lateral movement of the first cleaning plate 81 and the second cleaning plate 86, the surface of the copper wire is annealed. The annealed copper wire is then passed through the heat-insulating gypsum board 10 and guided to the paint spray head 14 set below the paint supply pipe 3.

[0046] Step 5: The spray head 14 sprays and cleans the surface of the copper wire, thereby performing anti-corrosion treatment on the metal surface. At the same time, the servo motor 4 drives the fan blade disk 94 to rotate, thereby accelerating the air flow speed inside the aluminum heat absorption disk 93. The heated air is continuously injected into the annealing shell 2 through the threaded joint 95 and the air supply pipe 92 on one side, thereby heating the surface of the wire and accelerating the drying speed of the paint on the surface of the wire. The collection roller 1 is opened to collect the enameled wire.

[0047] Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or equivalent to the scope of this invention are included in this invention.
