Double-vacuum-box foam breaker

Abstract

The invention relates to a double-vacuum-box foam breaker. The double-vacuum-box foam breaker is characterized by comprising a rack, conveying lines and foam breaking units, wherein the conveying lines and the foam breaking units are arranged on the rack; the at least three conveying lines are arranged, and each conveying line transversely extends and is vertically distributed on the rack at intervals; the foam breaking units are in one-to-one correspondence with the conveying lines, the foam breaking units are divided into vacuum foam breaking units and rolling foam breaking units, and the atleast two vacuum foam breaking units are arranged; each vacuum bubble breaking unit comprises a vacuum box located above the corresponding conveying line and a lifting mechanism for driving the vacuum box to lift; and each rolling foam breaking unit comprises at least two rolling foam breaking assemblies distributed in the length direction of the corresponding conveying line at intervals, each rolling foam breaking assembly comprises a lower end rolling wheel part arranged on the corresponding conveying line and an upper end rolling wheel part correspondingly arranged above the lower end rolling wheel part, and gaps forming rolling channels are formed between the upper end rolling wheel parts and the lower end rolling wheel parts. The foam breaker has the advantages of being wide in application range, high in working efficiency and capable of completely opening foam and avoiding product fracturing.

Description

technical field [0001] The invention relates to the field of foam breaking machines, in particular to a double vacuum box foam breaking machine. Background technique [0002] When the production of automobile foam products is completed, due to the characteristics of the products in production, there are a large number of airtight gas groups in the foam products after demoulding and foaming, which makes the product texture hard and lacks elasticity. Therefore, it is necessary to perform foam breaking treatment on the foamed product, so that the foam pores inside the foamed product are broken and communicated, so that the foamed product is breathable and its elasticity is increased, and at the same time, the air permeability of the product is increased. The most commonly used foam breaking method in the prior art is physical foam breaking. Physical foam breaking generally uses vacuuming or extrusion to break bubbles, while existing devices mostly use a single method of vacuum ...

AI Technical Summary

Problems solved by technology

The most commonly used foam breaking method in the prior art is physical foam breaking. Physical foam breaking generally uses vacuuming or extrusion to break bubbles, while existing devices mostly use a single method of vacuum breaking or rolling foam breaking. And because some automotive foam products, such as some seat cushions, have a metal skeleton, only the vacuum bursting method can be used to achieve the foam breaking effect.

Furthermore, the existing mechanical rolling and foam breaking are prone to incomplete foam opening or fracturing products.

Therefore, the existing equipment cannot be well applied to the production of various foam products at the same time
