Strip cutter for polytetrafluoroethylene sealing tape for thread sealing

Abstract

The invention discloses a strip cutter for polytetrafluoroethylene sealing tape for thread sealing. The strip cutter comprises a rack, a motor, a speed reducer, a decoiling device, tension rollers, a cutting device and a coiling device. The cutting device is arranged between the decoiling device and the coiling device. The decoiling device, the tension rollers, the cutting device and the coiling device are arranged on the rack. The tension rollers are arranged on the two sides of the cutting device. The coiling device comprises an upper coiling device body and a lower coiling device body, wherein the upper coiling device body and the lower coiling device body are used for containing tape winding cylinders. The sealing tape passing through the cutting device conducts cylinder winding through the upper coiling device body and the lower coiling device body. The motor drives the coiling device to rotate. The speed reducer is connected between the motor and the coiling device. The strip cutter has the beneficial effects that the strip cutter for the polytetrafluoroethylene sealing tape cuts original wide sealing tape into sealing tape which is narrow in upper part and lower part in a spaced manner, cylinder winding is carried out, the production efficiency can be improved, and the sealing tape can be prevented from being drawn and deformed.

Description

technical field [0001] The invention belongs to the field of fluoroplastic production, and in particular relates to a polytetrafluoroethylene raw tape cutting machine for thread sealing. Background technique [0002] PTFE tape for thread sealing (hereinafter referred to as raw tape) is an auxiliary product commonly used in daily life or industry. It is used for the joints of pipe fittings and thread seals to enhance the airtightness of pipe joints. It is a novel and ideal sealing material. It is widely used in water treatment, natural gas, chemical industry, plastics, electronic engineering and other fields due to its non-toxic, odorless, excellent sealing, insulation and corrosion resistance. In the production process of the raw material tape, it is necessary to cut the wide-width raw material tape into a narrow-width raw material tape, which is more suitable for daily use, but the existing cutting equipment cannot meet the requirements. After cutting, it is easy to pull t...

AI Technical Summary

Problems solved by technology

In the production process of the raw material tape, it is necessary to cut the wide-width raw material tape into narrow-width raw material tape, which is more suitable for daily use, but the existing cutting equipment cannot meet the requirements.

After cutting, it is easy to pull the raw material tape during the winding process, resulting in uneven width of the raw material tape, which affects the use
