Preparing device of blockboard

Abstract

The invention belongs to the technical field of heat preservation material machining equipment and relates to a device which manufactures a color steel blockboard with an on-line composite extruded sheet as core materials. A feeder of the device is communicated with an extruding machine. A compressed air pump is respectively communicated with the feeder, an on-line hair side machine, an edge milling slotting integrated machine and a first horizontal cutter. The extruding machine is connected with a cooling support through a first traction machine. The on-line hair side machine, the edge milling slotting integrated machine, the first horizontal cutter, a manpower composite feeder, a steel sheet uncoiler, a steel sheet necking machine, a color steel sheet composite machine and a second horizontal cutter are connected in sequence through a second traction machine. A line hanger is fixed arranged above the steel sheet uncoiler and the steel sheet necking machine. The color steel blockboard manufactured by the device is smooth in board shape, cold loss and air leakage phenomena are removed, heat preservation effect is good, whole equipment is easy to assemble and convenient to mount, and product quality is good.

Description

Technical field: [0001] The invention belongs to the technical field of thermal insulation material processing equipment, and relates to a device for manufacturing color steel sandwich panels with an online composite extruded board as a core material, in particular to a sandwich panel preparation device. Background technique: [0002] At present, the demand for sandwich panels in the domestic market has been increasing every year. With the rapid development of the cold chain logistics industry, the investment and construction of cold storage is at an all-time high. The market demand has given birth to the development of insulation, refrigeration materials and other related industries. The board is the necessary material for the insulation of the new prefabricated cold storage maintenance system. The sandwich panel is composed of two layers of formed metal panels (or other material panels) and a polymer heat insulation core that is directly foamed and cured in the middle of t...

AI Technical Summary

Problems solved by technology

The sandwich panel is composed of two layers of formed metal panels (or other material panels) and a polymer heat insulation core that is directly foamed and cured in the middle of the panels. The sandwich panel has the characteristics of light weight, high efficiency, thermal insulation and easy installation. and other characteristics, it is widely used in cold storage insulation layer and other fields; the production process of traditional sandwich panels is mostly made of extruded board core materials by extruded board production lines, and then the core materials are cooled and then sent to the color steel composite production line for color For the production of steel sandwich panels, the two production lines are independent in time and space, and due to the traditional production process of extruded panels, the air in the cells of extruded panels cannot be cooled immediately after production, and tends to expand after a period of expansion. Because of stability, it is difficult to closely combine the two when processing with the color steel panel, especially after the color steel plate is composited at both sides of the edge, due to the continuous expansion and contraction of the extruded board, the color steel plate cannot be just joined with the extruded board , leading to a certain degree of distortion in the plate shape, causing the male and female grooves of the color steel sandwich panel to be unable to be effectively inserted during installation, and gaps and other phenomena appear, resulting in cold bridges and cold running phenomena in these parts, which is not conducive to the insulation of the cold storage
