Description

Technical Field

[0001] This utility model relates to the field of measuring tooling technology, specifically to an enameling machine for producing enameled wire with an function to remove excess paint. Background Technology

[0002] The copper core of the cable needs to be drawn multiple times to reach the predetermined wire diameter. After that, it needs to be coated with insulating varnish and then with outer layer of rubber. Before the varnish is applied, the cable core has already gone through the enameling machine and completed a long winding and unwinding process. The surface is covered with a lot of oil and dust. Therefore, before leaving the enameling machine and applying insulating varnish, the cable must be cleaned to remove oil and dust.

[0003] Enameling machines are essential equipment in the enameled wire industry for producing enameled wires. Their function is to uniformly coat the processed copper wires with a layer of insulating polyester varnish. The varnish used in the production process contains a large amount of thinner and organic solvents, mainly benzene, xylene, and cresol, which volatilize when the varnish film is heated and cured. Existing enameling machines for cable production have relatively fixed molds, which cannot be quickly changed according to the diameter of the cable to be processed. Therefore, we need to propose an enameling machine for producing enameled wires that can remove excess varnish. Utility Model Content

[0004] The purpose of this utility model is to provide an enameling machine for producing enameled wire with an function to remove excess paint. By using a positioning groove, a limiting block, a snap-fit ​​assembly, and a support rod in combination, the problems mentioned in the background art can be solved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an enameling machine for producing enameled wire with an function to remove excess paint, comprising a base, the base having an internal cavity, a washing tank, a drying component, a paint-applying tank, and a shaping mold arranged on one side of the cavity, the shaping mold having a mold core inside, a screw fixedly connected to the bottom of the shaping mold, the screw being threadedly connected to the inside of a support rod, a limit block fixedly connected to the bottom of the support rod, a positioning groove being formed on the inner bottom wall of the cavity inside the base, the limit block being engaged in the positioning groove, and several sets of grooves being formed on the inner wall of the positioning groove, each set of grooves having a corresponding limit component inside.

[0006] Preferably, each set of limiting components includes a limiting rod and a limiting spring. One end of each limiting spring is fixedly installed inside the groove, and the other end is fixedly connected to one end of the corresponding limiting rod.

[0007] Preferably, the outer side of the limiting block is provided with several sets of limiting grooves, which can be used in conjunction with the limiting rod.

[0008] Preferably, the cavity inside the base is provided with a number of sets of active rollers and driven rollers, and each set of active rollers and driven rollers is provided with an arc-shaped groove, in which a cable is held.

[0009] Preferably, the outer side of the base is provided with several sets of baffles, and the top of each set of baffles is provided with a corresponding grinding component. Each set of grinding components includes a motor, a transmission rod and a grinding block. The motor is mounted on the baffle, and the output end of the motor is fixedly connected to one end of the transmission rod through a coupling. The end of the transmission rod away from the motor is rotatably connected to the inside of the base and extends into the cavity inside the base. The end of the transmission rod located in the cavity inside the base is fixedly connected to one end of the grinding block.

[0010] Preferably, the drying assembly includes a support frame and a drying heating ring. One end of the support frame is fixedly connected to the inner bottom wall of the base cavity, and the other end is fixedly connected to the drying heating ring. A heating device is provided inside the drying heating ring.

[0011] Preferably, a fan is provided on the top of the base, an air inlet is provided on the base, the fan is connected to the cavity inside the base through the air inlet, and an air outlet is connected to the top of the fan.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model facilitates the disassembly of the limiting block by using a positioning groove, a recess, and a snap-fit ​​assembly, thereby enabling quick replacement of the forming mold. This allows for the replacement of different forming molds depending on the required cable diameter. Specifically, the limiting block and the positioning groove are relatively fixed by a snap-fit ​​assembly, i.e., by the cooperation of the recess, the limiting rod, and the limiting spring, thus enabling quick replacement of the forming mold.

[0014] 2. Through the design of the grinding component, this utility model can easily use a motor to drive the grinding block to grind the surface of the cable to be processed, preventing impurities such as oil stains that have not been cleaned from adhering to the cable to be processed, so that the cable surface is not easy to adhere to the paint during the subsequent painting process, resulting in substandard product quality.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an enameling machine for producing enameled wire with a function to remove excess paint, comprising a base 1, the base 1 having a cavity inside, a washing tank 2, a drying component, a paint-applying tank 11, and a shaping mold 15 arranged on one side of the cavity, the shaping mold 15 having a mold core inside, a screw fixedly connected to the bottom of the shaping mold 15, the screw being threadedly connected to the inside of a support rod 14, a limiting block 13 fixedly connected to the bottom of the support rod 14, a positioning groove 101 being formed on the inner bottom wall of the cavity inside the base 1, the limiting block 13 being engaged in the positioning groove 101, a plurality of sets of grooves 16 being formed on the inner wall of the positioning groove 101, each set of grooves 16 having a corresponding limiting component 17 inside, wherein each set of limiting components 17 includes a limiting rod and a limiting spring, one end of each set of limiting springs being fixedly installed inside the groove 16, and the other end being fixedly connected to one end of the corresponding limiting rod.

[0023] Furthermore, a plurality of limiting grooves 131 are provided on the outer side of the limiting block 13, and the limiting grooves 131 can be used in conjunction with the limiting rod.

[0024] In this embodiment, the spacing of the positioning grooves 101 is greater than the thickness of the limiting block 13, thereby ensuring that the limiting block 13 can be inserted into the positioning groove 101. The interior of the groove 16 can accommodate the limiting component 17. The diameter of the limiting groove 131 is greater than the diameter of the limiting rod included in the limiting component 7, thereby ensuring that the limiting rod can be inserted into the limiting groove 131. A threaded hole is provided on the support rod 14. A screw is fixedly connected to the bottom of the shaping mold 15. The screw can be threaded into the threaded hole on the support rod 14. A mold core is provided inside the shaping mold 15. The mold core is provided with a through hole. One end of the through hole has a larger opening and the other end has a smaller opening. One end of the shaping mold 15 is located above the paint tank 11. In summary, in actual use, the operator can press the support rod 14 to drive the limiting block 13 into the positioning groove 101. During the process, the limiting block 13 is subjected to force by squeezing the limiting rod and the limiting spring. When the limiting rod is aligned with the limiting groove 131, the limiting rod is inserted into the limiting groove 131 under the action of the limiting spring, thereby achieving relative fixation between the limiting block 13 and the positioning groove 101. When it is necessary to replace the shaping mold 15, the support rod 14 is pulled to move the limiting block 13 out of the positioning groove 101, and then the shaping mold 15 is rotated to make the screw at the bottom of the shaping mold 15 disengage from the support rod 14. Then the shaping mold 15 can be replaced. Since one end of the shaping mold 15 is located at the top of the paint tank 11, and the through hole opened on the mold core inside the shaping mold 15 is larger at one end and smaller at the other end, when the cable 6 passes through the shaping mold 15, the excess paint is removed by the shaping mold 15 and falls back into the paint tank 11, thereby facilitating the reuse of paint.

[0025] Furthermore, the cavity inside the base 1 is provided with several sets of active rollers 7 and driven rollers 8, and each set of active rollers 7 and driven rollers 8 is provided with an arc-shaped groove, in which a cable 6 is held.

[0026] Furthermore, the outer side of the base 1 is provided with several sets of baffles 4, and the top of each set of baffles 4 is provided with a corresponding grinding component 5. Each set of grinding components 5 includes a motor 51, a transmission rod 52 and a grinding block 53. The motor 51 is mounted on the baffle 4, and the output end of the motor 51 is fixedly connected to one end of the transmission rod 52 through a coupling. The end of the transmission rod 52 away from the motor 51 is rotatably connected to the inside of the base 1 and extends into the cavity inside the base 1. The end of the transmission rod 52 located in the cavity inside the base 1 is fixedly connected to one end of the grinding block 53.

[0027] Preferably, the drying assembly includes a support frame 9 and a drying heating ring 10. One end of the support frame 9 is fixedly connected to the inner bottom wall of the cavity of the base 1, and the other end is fixedly connected to the drying heating ring 10. A heating device is provided inside the drying heating ring.

[0028] It is worth noting that a fan 3 is provided on the top of the base 1, and an air inlet 32 ​​is provided on the base 1. The fan 3 is connected to the cavity inside the base 1 through the air inlet 32, and an air outlet 31 is connected to the top of the fan 3.

[0029] In this embodiment, in actual use, a filter device should also be installed on the top of the fan 3 to filter and purify the harmful gases generated during the drying process, which can reduce environmental pollution and effectively avoid harm to the health of workers. A through groove is provided in the center of the drying heating coil 10, and the diameter of the through groove is larger than the diameter of the cable 6, so that the cable 6 can pass through the through groove in the center of the drying heating coil. Three sets of support frames 9 and drying heating coils 10 are provided. A through hole is opened on the base 1, and the diameter of the through hole is larger than the diameter of the transmission rod 52, so as to ensure that the transmission rod 52 can be driven by the motor. Motor 51 drives the grinding block 53 to rotate around itself. There are two sets of grinding components, which are symmetrically arranged. In summary, in actual use, motor 51 can drive the grinding block 53 to rotate, thereby grinding the surface of cable 6. This facilitates the subsequent coating process on the surface of cable 6, increasing the adhesion of the paint on the surface of cable 6. The drying component can quickly dry the paint on the surface of cable 6, making it easier to collect cable 6 later. The fan 3 can collect and purify the harmful gases generated during the drying process of cable 6, reducing or minimizing pollution to workers and the environment.

[0030] It should be noted that the heating device, fan 3 and motor 51 inside the drying heating ring 10 are powered and operate, and the driving roller 7 and driven roller 8 are driven by external power devices such as motors so that they can rotate around their own center. These are all existing technologies and will not be elaborated here.

[0031] 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.
