Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 , figure 2 and image 3 As shown, the present invention includes a pre-exposure machine 1, and also includes a box body 3 arranged on the outer wall of the pre-examination machine. The upper end surface of the box body 3 is not closed, and the bottom of the box body 3 is provided with a metal filter screen 4, and A strengthened glass 2 is provided at the junction of the outer wall of the engine relative to the box body 3 . The box body 3 in this embodiment is a rectangular structure.

[0013] Compared with the prior art, it is not only simple in structure and strong in practicability, but also through the setting of the metal filter 4, it is easy to pass through the top of the box body 3, and observe the situation in the pre-blowing machine through the tempered glass 2, and grasp it at any time The pre-expanded state of the foam.

Abstract

The invention relates to a foam product pre-expander, and in particular relates to an intermittent pre-expander observation device. The intermittent pre-expander observation device comprises a pre-expander and is characterized by also comprising a box body which is arranged on the outer wall of the pre-expander, wherein the upper end surface of the box body is unsealed; a metal filter screen is arranged at the bottom of the box body; tempered glass is arranged at a joint between the outer wall of the pre-expander and the box body. Compared with the prior art, the intermittent pre-expander observation device is simple in structure and high in practicality; by the adoption of the metal filter screen, the internal situation of the pre-expander can be easily observed, and the pre-expansion state of foam plastic is mastered at any time.

Description

technical field [0001] The invention relates to a foam product pre-expansion machine, in particular to an intermittent pre-expansion machine observation device. Background technique [0002] Styrofoam packaging boxes or packaging pads have the characteristics of light weight and good shock resistance, and are widely used in medical, food, electromechanical, instrumentation and hardware, as well as daily product packaging. The processing of EPS foam plastics is to put EPS raw material particles into the film cavity, use steam input to foam, and then pass water in the mold to cool, so that the foam product is separated from the metal mold, and then pass water and compressed air to demould while opening the mold. The structure of the traditional foam pre-expansion machine is unreasonable. The internal foam pre-expansion state and internal capacity cannot be observed, and the pre-expansion effect is difficult to grasp. Contents of the invention [0003] In order to overcome t...
