Automatic magnetic strip passing machine

Abstract

The invention discloses an automatic magnetic strip passing machine. The automatic magnetic strip passing machine comprises a rack and a magnetic strip tractor, wherein the magnetic strip tractor is positioned on the rack, a magnetic strip passes through a guide rod, a pressing wheel and the magnetic strip tractor in sequence, the magnetic strip tractor comprises two conveying machines respectively including an upper conveying machine positioned on the top and a lower conveying machine positioned at the bottom, an upper guide groove is formed in one surface, which is opposite to the lower conveying machine, of the upper conveying machine, a lower guide groove which is opposite to the upper guide groove is formed in the lower conveying machine, a conveying belt of the upper conveying machine is arranged in the upper guide groove, a conveying belt of the lower conveying machine is arranged in the lower guide groove, the magnetic strip is positioned in a gap formed by the conveying belts of the upper conveying machine and the lower conveying machine and is clamped to move forward by the conveying belts of the upper conveying machine and the lower conveying machine, and the gap is positioned in the upper guide groove or the lower guide groove. According to the automatic magnetic strip passing machine, whether the magnetic force of the magnetic strip is qualified can be automatically detected, the traction of the magnetic strip does not slip, the cutting length of the magnetic strip is accurate, the qualified rate of products is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of sealing strip production equipment, in particular to an automatic magnetic strip threading machine. Background technique [0002] In the production of refrigerators and freezers, sealing strips are required, and magnetic strips need to be inserted into the sealing strips to achieve a better sealing effect. The magnetic strip threading machine is to penetrate the magnetic strips into the sealing strips. The existing The magnetic strip traction equipment is driven by a chain. The magnetic strip is adsorbed on the chain by its own magnetic force, and the chain advances to drive the magnetic strip to advance. The existing transmission method is prone to slipping, Due to hysteresis and other phenomena, the magnetic strip cannot meet the cutting size requirements, and the reject rate of door seals is too high, resulting in excessive production costs. Contents of the invention [0003] Aiming at the problems ...
