Embodiment 1

[0047] The multi-channel temperature control step is five-channel temperature control, and the five-channel temperature control of the five channels includes a main channel and four auxiliary channels, and the cross-sectional shapes of the four sections of the auxiliary channels are as follows: Figure 4 As shown, the main channel forms an initial wrapping effect on the anchor chain, and the four auxiliary channels wrap the anchor chain passing through the main channel in all directions from the four sections.

Embodiment 2

[0049] The multi-channel temperature control step is four-channel temperature control, the four-channel temperature control in the four channels includes a main channel and three auxiliary channels, and the cross-sectional shapes of the three sections of the auxiliary channels are as follows: Figure 5 As shown, the main channel forms an initial wrapping effect on the anchor chain, and the three auxiliary channels wrap the anchor chain passing through the main channel from three sections in all directions.

Embodiment 3

[0051] The multi-channel temperature control step is three-channel temperature control, and the three-channel temperature control of the three channels includes a main channel and two auxiliary channels, and the cross-sectional shapes of the two sections of the auxiliary channel are as follows: Image 6 As shown, the main channel forms an initial wrapping effect on the anchor chain, and the two auxiliary channels respectively wrap the anchor chain passing through the main channel from two sections.

Abstract

The invention provides a one-time rapid prototyping method for plastic coating of an elevator balance compensation chain, comprising the following steps: compounding and mixing polymer materials; extruding and shearing the polymer materials; extruding and shearing the polymer materials Extruded and heated to form a viscous flow; the viscous flow polymer material enters the main channel to form an initial wrapping effect on the anchor chain; Wrapping and feeding to form a uniform wrapping layer; finally cooling and forming. The one-time rapid prototyping method of elevator balance compensation chain plastic coating provided by the present invention changes the traditional method of extruding and wrapping by multiple single-screw divisions and secondary heating, and adopts the method of one-time extrusion molding and one-time heating of a single screw, so that Avoiding the aging of polymer materials caused by repeated heating, prolonging the service life of polymer materials and elevator balance compensation chains; also greatly reducing the investment in manpower, equipment, energy and time.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a one-time rapid prototyping method for plastic coating of an elevator balance compensation chain. Background technique [0002] The elevator balance compensation chain is a component that balances the operation of the elevator. It is required to have the characteristics of large load, low operating noise, and weight per unit length. [0003] In the prior art, the preparation method of the elevator balance compensation chain usually includes the following methods: [0004] 1. It adopts electric welding anchor chain wrapped with PVC plastic, and is produced by extrusion molding. [0005] 2. Welded anchor chain is used to wrap rubber and fiber, and it is produced by molding rubber vulcanization. [0006] 3. Use a sisal rope in the middle of the electric welding anchor chain to eliminate the noise during the lifting process of the product. [0007] 4. Steel wire rope ...
