Oppositely-openable type polyester yarn insulated casing braiding machine heating and setting device

Abstract

The invention relates to an oppositely-openable type polyester yarn insulated casing braiding machine heating and setting device. The device includes a base, a rack, yarn shafts and a heating and setting device; the rack is fixed at the upper part of the base; the base is provided with the yarn shafts and reels; the top of the rack is provided with a casing leading-out wheel; the rack is providedwith the heating and setting device above the yarn shafts; the heating and setting device is an automatically oppositely-openable type heating and sizing device and includes two semicircular heating sleeves; the rear parts of the semicircular heating sleeves are fixedly provided with moving seats; the moving seats are mounted on a screw rod driven by a servo motor in a meshed manner; and the moving seat mounted on the two semicircular heating sleeves are oppositely meshed to the screw rod; the servo motor drives the two semicircular heating sleeves to perform relative opening and closing operation; and the servo motor and the screw rod are mounted on a horizontal frame that is laterally fixed above the reels. The structural design of the device of the invention is scientific and reasonable. With the device adopted, the wall thickness of polyester yarn insulated casings can be uniform, and the pipe diameters of the polyester yarn insulated casings can be consistent, and the production and use of the polyester yarn insulated casings by end users can be effectively ensured.

Description

technical field [0001] The invention belongs to the field of processing equipment for fiber insulated wires and cables, in particular to a heating and setting device for a split-type polyester wire insulating sleeve braiding machine. Background technique [0002] Polyester wire insulating braided sleeve is an insulating protective layer tightly wrapped around the metal wire, which can insulate and withstand voltage and protect the metal wire bundle. In order to ensure the normal use of the polyester wire insulating braided sleeve, the finished product must have good flatness and uniform pipe diameter; therefore, it is necessary to heat and shape the sleeve after the polyester wire braiding process. [0003] At present, the commonly used heating and setting method is to heat and shape the braided sleeve separately in the subsequent process of weaving, that is, weave the polyester silk insulating braided sleeve first, and then make it pass through a flat (vertical) heating jac...

AI Technical Summary

Problems solved by technology

Since the finished product of the braided sleeve is continuous and the length is very long, the heating sleeve is required to have a certain height, which causes disadvantages such as the heating sleeve occupies a large space, is difficult to manufacture and assemble, and has high production costs.

Moreover, the quality of the polyester wire insulating braided sleeve treated by this heating and shaping method is difficult to guarantee, and its diameter is often inconsistent, which affects the processing and use of end users.

[0004] The existing split-type heating and setting device installed on the frame has a simple structure and needs to be opened and closed manually, which has the problems of inconvenient operation and low degree of automation, and there are safety hazards in manually opening and closing the heating jacket. When the temperature of the heating jacket is too high, it is easy to cause a safety accident
