Hydraulic cold-pressed encryption equipment

Abstract

The invention relates to hydraulic cold-pressed encryption equipment, which has the characteristics of simple structure, convenience to use, environmental protection and safety. The hydraulic cold-pressed encryption equipment can prevent materials inside a discharge hole of a charging barrel from being plasticized, and comprises a grinding device and a feeding cylinder distributed in an enclosure from top to bottom successively. A threaded rod for transmitting the materials grinded by the grinding device out of the feeding cylinder is arranged inside the feeding cylinder. A discharge hole of the feeding cylinder is connected to a material inlet of a material-pressing cylinder. One end of the material-pressing cylinder is provided with a hydraulic cylinder and the other end of the material-pressing cylinder is an encrypted material outlet, wherein the encrypted material outlet is provided with a baffle for controlling opening or closing of the encrypted material outlet. A piston of the hydraulic cylinder is suitable to stretch into the material-pressing cylinder and press the materials to the encrypted material outlet. According to the hydraulic cold-pressed encryption equipment provided by the invention, the hydraulic cylinder is adopted to extrude the materials, and therefore the encryption of the materials is implemented; and during the process of encryption, the frictions caused by materials such as foamed plastics are reduced, so that phenomenons such as plasticization, smoking and the like do not generate. The hydraulic cold-pressed encryption equipment is convenient to use as well as environment-friendly and safe.

Description

technical field [0001] The invention relates to a hydraulic cold-press encryption machine, which is used for cold-press processing discarded foamed plastics and other materials that can be greatly compressed, so as to greatly reduce their volume and facilitate transportation. Background technique [0002] Expandable polystyrene (EPS), expandable polypropylene (EPP), expandable high-pressure polyethylene (EPE) and other foamed plastics have good heat insulation, sound insulation, shockproof and other properties, and their applications are becoming more and more extensive. The recycling of discarded foamed plastics can not only protect the environment and save energy, but also has good economic benefits. One of the current waste foam plastic processing methods is cold pressing. [0003] The existing cold-press encryption machine includes: a frame and a machine casing, the top of the machine casing is provided with a feed port, a crushing device is arranged in the machine casi...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the above-mentioned existing cold-pressing machines are: thermoplastic materials such as foamed plastics, under the action of the screw, tend to be plasticized and smoke at the discharge port of the barrel, thereby producing harmful gases and polluting In addition, once the cold press machine is shut down, the material in the discharge port of the barrel will solidify, and manual excavation is often used to remove the solidified material. This method is obviously time-consuming and laborious, and affects production efficiency.
