Soft bag tearing machine

Abstract

The invention discloses a novel soft bag tearing machine which comprises a base and a shell. The shell is fixed to the base, and guide frames, a traction frame and a bag tearing frame are sequentially arranged on the base in parallel. Guide wheels are arranged on the guide frames. A traction wheel, a traction pressing wheel and a traction motor are arranged on the traction frame. A bag tearing wheel, a bag tearing pressing wheel and a bag tearing motor are arranged on the bag tearing frame. A switch, a traction wheel speed regulating knob, a traction wheel speed regulating meter, a bag tearing wheel speed regulating knob and a bag tearing wheel speed regulating meter are arranged on the shell. The traction motor is connected with the switch, the traction wheel speed regulating knob and the traction wheel speed regulating meter through wires. The bag tearing motor is connected with the switch, the traction wheel speed regulating meter, the bag tearing wheel speed regulating knob and the bag tearing wheel speed regulating meter through wires. A traction belt is arranged between a one-way wheel and the bag tearing wheel in a sleeving mode, and the traction wheel can drive the bag tearing wheel through the one-way wheel and the traction belt to enable the linear speed of the edge of the bag tearing wheel not to be lower than that of the edge of the traction wheel.

Description

technical field [0001] The invention relates to the technical field of cutting production and processing of soft plastic products with half-cut openings, in particular to a soft bag tearing machine. Background technique [0002] At present, in order to improve the production efficiency of continuous printing, soft plastic bag packaging adopts the method of pre-cutting a soft plastic bag with a half-cut opening, so as to realize the continuity of production, but this soft plastic bag with a half-cut opening is produced separately. At the same time, it is often used to manually tear open the half-cut opening to make a single soft plastic bag and then produce it. This method greatly increases labor costs and reduces production efficiency. The reasonable body size is very large plus the disadvantages of high price, complicated operation and high energy consumption, and the effect is not ideal. On the other hand, there are many defects in the way of using the bracket to guide th...

[0002] At present, in order to improve the production efficiency of continuous printing, soft plastic bag packaging adopts the method of pre-cutting a soft plastic bag with a half-cut opening, so as to realize the continuity of production, but this soft plastic bag with a half-cut opening is produced separately. At the same time, it is often used to manually tear open the half-cut opening to make a single soft plastic bag and then produce it. This method greatly increases labor costs and reduces production efficiency. The reasonable size is large, and the price is expensive, the operation is complicated, and the energy consumption is high, and the effect is not ideal.

On the other hand, there are many defects in the way of using the bracket to guide the advance. If the bracket is not smooth enough, or the plastic paper is too thin, it is easy to form wrinkles on the bracket, which will cause blockage.

On the other hand, the traditional frame for transporting bags is fixed and cannot be adjusted in speed, so the pulling force provided is constant and the applicability is reduced
