A continuous production method and equipment for polyurethane sandwich panels with eccentric locks

Abstract

The invention discloses a method and equipment for continuous production of a polyurethane sandwich panel with eccentric lock catches and belongs to the technical field of manufacturing of polyurethane sandwich panels. The continuous production method comprises the following steps: (1), utilizing a molding machine to form the shapes of slots in the two sides of an upper plate and a lower plate; (2) calculating a distance between the adjacent eccentric lock catches, and processing bayonets in positions, in which the eccentric lock catches need to be installed, of the lower plate according to the distance; (3), respectively fixing male heads and female heads of the eccentric lock catches at the left side and the right side of the lower plate through the bayonets; (4), continuously and uniformly injecting a polyurethane foaming material between the upper plate and the lower plate, and carrying out compound molding on the upper plate, the lower plate and the polyurethane foaming material; (5) cutting the compounded sandwich panel. According to the invention, the continuous production of the polyurethane sandwich panel with the eccentric lock catches is realized, the production efficiency and the product quality are improved, and the non-stop production of the same length of polyurethane sandwich panels with the eccentric lock catches in the consistent positions and the non-stop production of different lengths of polyurethane sandwich panels are realized.

Description

technical field [0001] The invention relates to a production method and equipment of polyurethane sandwich panels, more specifically, to a continuous production method and equipment of polyurethane sandwich panels with eccentric locks for cold storage. Background technique [0002] At present, the domestically produced polyurethane color steel sandwich panels with eccentric locks are mainly manufactured by non-continuous production of laminating machines. When producing polyurethane color-steel sandwich panels with eccentric locks, it is necessary to fix the eccentric locks on the surrounding modules of the laminator table, and place the color steel plates rolled over the edges on the upper and lower sides, and place them between the upper and lower color steel plates. Polyurethane small squares are used to support the upper color steel plate, and at the same time ensure that there is enough space between the upper and lower color steel plates, and then enter the laminator, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the disadvantages of the existing polyurethane sandwich panels with eccentric locks, such as low production efficiency, large product quality differences, easy dislocation of eccentric locks and poor joint ability during production, and to provide an eccentric lock The continuous production method and equipment of polyurethane sandwich panels with buckles adopt the technical scheme of the present invention to realize the continuous production of polyurethane sandwich panels with eccentric locks, improve production efficiency and product quality, and simultaneously realize the same length The position of the eccentric lock of the polyurethane sandwich panel is consistent, which is convenient for joint installation. In addition, it also realizes the non-stop production of polyurethane sandwich panels of different lengths. The maximum length of a single polyurethane sandwich panel is not limited by the equipment
