Problems solved by technology

In addition, the sheet is heated and foamed while being rolled up in the vertical foaming furnace. The height of the vertical foaming furnace will make the sheet immediately come out of the outlet of the vertical foaming furnace after foaming, and the degree of cooling is not enough.
At the same time, in order to ensure the heating time and degree of the sheet in the vertical foaming furnace, the winding speed of the sheet is low, which also leads to low production capacity of the equipment

Embodiment Construction

[0026] The following are specific embodiments of the present invention, and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] A vertical foaming equipment, such as figure 1 As shown, it includes a furnace body 100, a heating field arranged in the furnace body 100, and a roller set 200 for sending the sheet to be foamed into the furnace body 100 for foaming and winding the foamed sheet The furnace body 100 includes a horizontal preheating furnace 110 and a vertical foaming furnace 120 in sequence.

[0028] Under the power of the roller group 200, the sheet to be foamed is preheated sequentially through the horizontal preheating furnace 110, enters the vertical foaming furnace 120 for foaming, and is wound up to obtain a finished product. Wherein, the speed of the roller set 200 determines the productivity efficiency of the equipment.

Abstract

The invention relates to the technical field of foaming furnaces, in particular to vertical foaming equipment. The vertical foaming equipment comprises a furnace body, a heating field formed in the furnace body and a roll set, wherein the roll set is used for sending a to-be-foamed sheet into the furnace body to be foamed and rolling up the foamed sheet; the furnace body sequentially comprises a horizontal preheating furnace and a vertical foaming furnace; the height of the vertical foaming furnace is 6-10 m, and the vertical foaming furnace comprises a first foaming section connected with thedischarging end of the horizontal preheating furnace; and the heating field comprises a high-temperature heating field formed in the first foaming section. The effects of high efficiency and energy conservation are achieved by increasing the height of the vertical foaming furnace.

Description

technical field [0001] The invention relates to the technical field of foaming furnaces, in particular to a vertical foaming equipment. Background technique [0002] Polyolefin plastics have a wide range of applications, have good physical, chemical and mechanical properties, good toughness, flexibility and cushioning properties, and have properties such as electrical insulation and heat insulation. They are widely used in packaging, chemical industry, construction and other fields. Polyolefin foams are widely used and one of the first foams to be successfully produced. [0003] At present, the cross-linked polyolefin foaming process is mainly to first knead and granulate the polyolefin raw materials and various additives, add them to the extruder for plasticization, and obtain a polyolefin master sheet with all components mixed uniformly, and then through foaming Furnace for foaming. There are two main types of foaming furnaces in general use. One is to use the horizontal...
