Embodiment 1

[0031] see Figure 1-Figure 4 , the present invention is used for the cold pressing machine that foamed plastics is carried out cold pressing briquetting comprises 3, is arranged on 3 and is used for conveying the feeding mechanism 1 of foamed plastics after crushing and is used for conveying to feeding mechanism 1 The cold-pressing briquetting mechanism 2 that the foamed plastic that comes over carries out cold-pressing.

[0032] see Figure 1-Figure 4The cold pressing briquetting mechanism 2 includes a compression chamber 2-1, a pressure applying plate 2-2 arranged on the compression chamber 2-1, and a device for driving the pressure applying plate 2-2 to complete the cold pressing action. A pressure driving mechanism 2-3, wherein the compression chamber 2-1 is provided with a transition chamber 4 at a position corresponding to the feeding mechanism 1, and the transition chamber 4 is an inverted funnel shape, wherein the The end with a smaller diameter in the transition ch...

Embodiment 2

[0041] see Figure 5 and Figure 6 , the difference between this embodiment and Embodiment 1 is that: there are two groups of helical blades in the first helical pushing mechanism 1-1 above, and the rotation directions of the two groups of helical blades are opposite, and one group of helical blades is arranged at One side of the intersecting section of the first screw pushing mechanism 1-1 and the second screw pushing mechanism 1-2, and another group of helical blades are arranged on the other side of the intersecting section, between the two groups of helical blades The intersecting section of is the blanking space without helical blades. Through the above setting, it has the following advantages:

[0042] (1), be conducive to reasonable layout, reduce the volume of cold press machine of the present invention.

[0043] (2), since the feed port of the first screw pushing mechanism 1-1 is connected with the discharge port of the buffer transition bin, the second screw pushi...

Abstract

The invention discloses a cold press for cold pressing and briquetting of foamed plastic. The cold press comprises a rack, a feeding mechanism and a cold pressing and briquetting mechanism. The cold pressing and briquetting mechanism comprises a compression cavity, a pressure applying plate and a pressure applying driving mechanism. A transition cavity is formed in a position, corresponding to thefeeding mechanism, of the compression cavity. One side of the transition cavity communicates with a discharging port of the feeding mechanism, and the other side of the transition cavity communicateswith a feeding port of the compression cavity. The cold pressing and briquetting mechanism further comprises an opening and closing mechanism used for closing or opening the feeding port of the compression cavity. The opening and closing mechanism comprises a blocking plate arranged on the pressure applying plate, and the blocking plate synchronously acts in the movement direction of the pressureapplying plate. When the pressure applying driving mechanism drives the pressure applying plate to compress the foamed plastic, the blocking plate synchronously moves along with the pressure applyingplate and blocks the feeding port in the compression cavity. The cold press is relatively high in cold pressing speed and efficiency, and the phenomena of machine jamming and the like are not likelyto happen.

Description

technical field [0001] The invention relates to a plastic recovery device, in particular to a cold press for cold pressing and briquetting foamed plastics. Background technique [0002] Foamed plastics, such as EPS, XPS and EPP, have good properties such as heat insulation, sound insulation, rigidity, good cushioning performance during impact, corrosion resistance, and low density. They are widely used in product packaging, heat insulation, sound insulation, impact resistance, etc. occasion. However, after use, foamed plastics need to be recycled. If they are discarded at will, they will easily become detritused in the environment. If these detritused foamed plastics flow into the sea with the rivers or remain in the soil, it will cause "white plastic". pollute". [0003] In the process of recycling foamed plastics, although the used foamed plastics have a high recycling value, due to their low density, they take up a lot of space during the collection process, making thei...
