Description

Technical Field

[0001] The utility model relates to the technical field of insulating core rod production, in particular to a device that effectively solves the whitening of a resin-impregnated insulating core rod. Background Art

[0002] The production of insulating core rods is mainly divided into two processes: injection process and dipping process. Since the injection process is difficult to achieve when producing core rods above φ50, the dipping process is currently used more in the production of large-diameter insulating core rods. However, in the autumn and winter seasons, the ambient temperature is low and the distance from the dipping pool to the mold entrance is approximately 1.5-2 meters. This distance is too long, and the temperature of the glass fiber after impregnation at the mold entrance is too low. At this time, the production of core rods is prone to whitening and internal cracks. The existing technology usually avoids the above problems by using air conditioning heating in an independent space. Not only is the cost high, but it is also difficult to reach the required temperature inside the wire harness in the autumn and winter seasons, and the whitening problem still exists, so further improvement is needed. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a device that effectively solves the problem of whitening of a resin-impregnated insulating core rod.

[0004] The purpose of the utility model is achieved through the following technical solutions: a device for effectively solving the whitening of the dipping insulating core rod, comprising a dipping tank, a roller, and a mold, wherein the roller is located in the dipping tank, and is characterized in that a support rod, a plurality of yarn dividing rods, and a preheating cylinder are arranged on the dipping tank, wherein the yarn dividing rods are fixedly connected to the support rods at horizontal intervals, the preheating cylinder is located between the yarn dividing rods and the mold, the preheating cylinder is arranged horizontally, and a heating channel is arranged in the preheating cylinder.

[0005] Furthermore, the preheating tube is a tubular structure, and a heating wire is provided on the inner wall of the preheating tube.

[0006] Furthermore, the support rod is provided with a thread, and the support rod is provided with a height adjustment assembly, and the height adjustment assembly includes a first fixing ring, a second fixing ring, a first adjusting nut, and a second adjusting nut. The first fixing ring and the second fixing ring are perpendicular to each other and fixedly connected. The first fixing ring is mounted on the yarn dividing rod, and the second fixing ring, the first adjusting nut, and the second adjusting nut are all mounted on the support rod. The second fixing ring is located between the first adjusting nut and the second adjusting nut.

[0007] Furthermore, a glue receiving plate is arranged in the preheating cylinder, and the glue receiving plate is arranged at an angle, and the glue receiving plate extends from the bottom of the mold to the opening of the glue dipping pool.

[0008] Furthermore, the yarn separation rod is a round rod made of chrome-plated or stainless steel.

[0009] The utility model has the following advantages:

[0010] By setting the yarn separation rod and the preheating cylinder, the yarn separation rod can separate the impregnated glass fiber, so that the external heat source can be easily radiated to the inside of the glass fiber, solving the problem of external heat and internal coolness, making the temperature of the glass fiber entering the mold uniform, and avoiding the phenomenon of whitening and internal cracks of the core rod; at the same time, the yarn separation rod props up the glass fiber, increases the tension, and the tightening of the glass fiber bundle is more conducive to the occurrence of impregnation; at the same time, the horizontal setting of the yarn separation rod can horizontally layer the glass fiber, and the excess glue will not flow directly into the glue receiving tray but flow from the upper glass fiber to the lower glass fiber, achieving the purpose of multiple impregnation; through the setting of the layered preheating structure, the yield rate of large-diameter core rods in the impregnation process is increased from the original 70-75% to 95-98%, greatly improving the product yield rate.

The roller shaft 2 is located in the dipped glue pool 1. The roller shaft 2 is used to press the glass fiber into the glue solution to complete the infiltration. The two support rods 7 are threaded rod structures. The two support rods 7 are vertically welded to the sides of the dipped glue pool 1 respectively. The five yarn dividing rods 8 are horizontally spaced and fixedly connected to the support rods 7. The five yarn dividing rods are made of chrome-plated rods. Five height adjustment components are installed on each support rod 7. The height adjustment components include a first fixing ring 9, a second fixing ring 10, a first adjusting nut 11, and a second adjusting nut 12. The first fixing ring 9 and the second fixing ring 10 are perpendicular to each other and welded. The first fixing ring 9 is mounted on the yarn dividing rod 8. The first fixing ring 9 is rotatably connected to the yarn dividing rod 8. The second fixing ring 10, the first fixing ring 11 and the second fixing ring 12 are rotatably connected to each other. The first adjusting nut 11 and the second adjusting nut 12 are both mounted on the support rod 7, and the second fixing ring 10 is located between the first adjusting nut 11 and the second adjusting nut 12.
