Description

Technical Field

[0001] The utility model belongs to the technical field of engineering plastics, and particularly relates to a cutting device for processing engineering plastics. Background Art

[0002] Engineering plastics can be used as engineering materials and as plastics to replace metals in manufacturing machine parts. Engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used for a long time in harsh chemical and physical environments and can replace metals as engineering structural materials. However, they are more expensive and have lower production volumes. Engineering plastics can be divided into two categories: general engineering plastics and special engineering plastics. The former mainly includes five general-purpose engineering plastics: polyamide, polycarbonate, polyoxymethylene, modified polyphenylene ether and thermoplastic polyester; the latter mainly refers to engineering plastics with heat resistance of more than 150°C, and the main varieties include polyimide, polyphenylene sulfide, polysulfone, aromatic polyamide, polyarylate, polyphenylene ester, polyaryletherketone, liquid crystal polymer and fluororesin. In the production and processing of engineering plastics, it is necessary to cut the strip-shaped engineering plastics into granular form to facilitate the subsequent processing and use of the engineering plastics. However, at present, the engineering plastics are cut manually because the engineering plastics are loaded manually during cutting. The manual loading cannot control the loading speed of the engineering plastics, which easily leads to different sizes of the engineering plastics, resulting in uneven cutting of the engineering plastics and affecting the cutting effect of the engineering plastics. Therefore, a cutting device for engineering plastics processing is needed. Utility Model Content

[0010] Preferably, the number of the limiting pulleys is six, and the limiting pulleys are located inside the loading positioning plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The small electric push rod starts to drive the limiting pulley to move. The limiting pulley is against both sides of the engineering plastic and slightly squeezes the engineering plastic.
