Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a cable core covering molding device. Background Art

[0002] The cable core overmolding device is an important cable manufacturing equipment. Its main function is to coat and mold the cable core to ensure the cable's electrical conductivity, mechanical strength and corrosion resistance. Through this device, the cable core can be coated at high speed, high efficiency and precision, which can improve production efficiency and reduce production costs. At the same time, it can reduce labor costs and improve production safety. In addition, the cable core overmolding device is also flexible and has a wide range of applications. It can meet the production needs of cables of different types and specifications. In general, the cable core overmolding device is of great significance in the cable manufacturing industry. It can improve production efficiency, reduce production costs, improve the performance and quality of cables, and meet the growing market demand.

[0003] The existing overmolding device overmoldes the cable core by passing it through a coating bin filled with insulating rubber. To prevent the core wire of the cable core from shifting during overmolding, a guide mechanism is provided at both ends of the coating bin. However, the following problems still exist in actual operation:

[0004] 1. During production, the outer surface of the cable core may be uneven. When the insulating glue is coated on the outside of the cable core, the outer surface of the cable after overmolding may be uneven, thereby affecting the quality of the finished cable. At the same time, when the insulating glue is coated on the outside of the cable core, the outer surface of the cable after molding may be uneven due to uneven feeding.

[0005] 2. Due to the different sizes of cable cores, when using the device to feed the cable cores, the guide mechanism needs to be adjusted according to the diameter of the cable core, thereby improving the versatility of the device. Utility Model Content
