Washing powder plastic bag manufacturing machine

Abstract

The invention discloses a washing powder plastic bag manufacturing machine and relates to the field of plastic machinery. The washing powder plastic bag manufacturing machine comprises a case; a motor is disposed at one end of the case and connected with a runner; the runner is connected with a pulling roller through a belt; a charging rack is disposed at the upper end of the case and connected with a feed roller; a length adjusting rod is disposed beside the feed roller; an electromagnetic heater is disposed beside the length adjusting rod; a cutter is arranged beside the electromagnetic heater; the pulling roller is disposed beside the cutter; the pulling roller is connected with a discharging device through a belt; the electromagnetic heater comprises an upper electromagnetic induction heating roller and a lower electromagnetic induction heating roller which are symmetrical, the electromagnetic heater makes the heating rollers to be self-heated by means of an electromagnetic induction principle, and advantages of low heat loss, short pre-heating time and energy and electricity saving are achieved. The washing powder plastic bag manufacturing machine is reasonable in structure, practical, convenient and suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the field of plastic machinery, in particular to a plastic bag manufacturing machine for washing powder. Background technique [0002] Plastic bags are widely used in food packaging, daily chemical products packaging and other fields. Plastic bags generally use a bag making machine. During the bag making process, the plastic film is heated and eagerly cut. The heating method of ordinary bag making machines is through resistance The wire generates heat, and the heat is transferred to the heating roller through contact conduction, and then transferred to the plastic film through the heating roller, but most of the heat in this heating method is lost to the air, and there is heat conduction loss, which leads to an increase in operating temperature and low power density. , the preheating time is slow, the power consumption is high, and the heating time and heating temperature cannot be guaranteed. A bag making machine with applic...

[0002] Plastic bags are widely used in food packaging, daily chemical products packaging and other fields. Plastic bags generally use a bag making machine. During the bag making process, the plastic film is heated and eagerly cut. The heating method of ordinary bag making machines is through resistance The wire generates heat, and the heat is transferred to the heating roller through contact conduction, and then transferred to the plastic film through the heating roller, but most of the heat in this heating method is lost to the air, and there is heat conduction loss, which leads to an increase in operating temperature and low power density. , the preheating time is slow, the power consumption is high, and the heating time and heating temperature cannot be guaranteed. A bag making machine with application number 200620137706.3 has cooling holes on its heating device, which can dissipate heat better during work, but Still can't solve the problem of low power density of heating device, slow warm-up time, high power consumption, and can't guarantee heating time and heating temperature
