Embodiment Construction

[0023] In view of the prior art, in the manufacturing process of the heat-shrinkable tube, the online cutting of the expansion of the circular tube, the cutting under the existing conditions will cause air leakage, which will affect the stability of the expansion and ultimately affect the quality of the product. The invention designs a special sealing clip, which is placed on the round tube product just after the expansion mold when the heat-shrinkable tube is expanded, which can play a good sealing role, and can realize expansion while cutting, avoiding the expansion of the tube The air leakage problem during the cutting process improves the stability of the expansion and ensures the product quality.

[0024] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompan...

Abstract

The invention discloses a seal clamp. The seal clamp comprises an upper pressing plate, a lower pressing plate, a guide wheel and a pull buckle; one end of the lower pressing plate is in pivot joint with one end of the upper pressing plate, the guide wheel is connected with the lower pressing plate, and the pull buckle is arranged at the other rend of the upper pressing plate and used for being fixedly connected with the lower pressing plate; when a heat shrinkage pipe expands, the pipe is placed on a round pipe product just out of an expansion mold, through alternative use of two seal clamps, cutting can be carried out while the round pipe is expanded, for different specifications, a rotating screw cap at the end of a pull rod is adjusted, and the seal effect is adjusted.

Description

technical field [0001] The invention relates to the technical field of polymer material pipe manufacture, and in particular to a sealing clip. Background technique [0002] Expansion is the core process in the production process of heat shrinkable tubes. The irradiated semi-finished product is heated to a high elastic state, and then the product is expanded to the required size through the internal pressure method, vacuum method or internal pressure and vacuum combination method. [0003] At present, the commonly used expansion methods include circular tube expansion and flat tube expansion. When the circular tube is expanded, the interior of the semi-finished pipe needs to be inflated, and some products need to be cut while expanding. [0004] For the online cutting of circular tube expansion, the cutting under the existing conditions will cause air leakage, which will affect the stability of the expansion and ultimately affect the product quality.
