Technical Field

The utility model belongs to pipe fitting production field, concretely relates to tubular product packagine machine's wrapping bag conveyer.

Background

The pipe extrusion line comprises an extrusion main machine, an extrusion die, a cooling water tank, a tractor, a cutting machine, a pipe packaging machine and the like. The quality of the outer package of the product affects the quality of the product. When traditional packagine machine was in the operation, when packagine machine stop work back, the last tray of packagine machine still can be because self inertia reason continues to rotate a section distance, causes the wrapping bag material extravagant and influences the packing effect to tubular product when packagine machine next time is worked.

Currently, in response to this drawback of the conventional packaging machines, devices are designed to brake the trays on the packaging machine to stop when the packaging machine stops bagging. The bag storage device of the existing pipe bagging packaging machine is characterized in that a brake device is arranged beside a discharged specification roll, when a bagging mechanism pulls a bag, a cylinder acts to loosen a brake pad and a bag disc through a fulcrum, when the bagging mechanism does not pull the bag, the cylinder cancels the action, and the brake pad presses the bag disc through the fulcrum to brake the bag disc. The device adopts the cylinder as a driving component to drive the brake block to compress the bag disc, and controls the cylinder to move in an electric signal mode. However, the electrical signal transmission is delayed and electrical elements are introduced, so that the electrical elements are easy to break down, the control of the device is disturbed, the control effect is influenced, and even the electrical elements or the air cylinder are damaged, so that the service life is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome the mode control cylinder motion of adopting the signal of telecommunication among the above-mentioned prior art, signal of telecommunication transmission has the delay, introduces the easy problem that breaks down of electrical components. The packaging bag conveying device of the pipe packaging machine is characterized in that the tray is controlled to rotate or be static through a mechanical transmission structure, the device is simple in structure, other electrical elements are not required to be introduced, signal delay is avoided, the mechanical structure is stable in operation and not prone to failure, and the service life is longer.

The utility model adopts the technical proposal that: a packaging bag conveying device of a pipe packaging machine comprises a rack, a tray, a guide rod, a bag sleeving mechanism, a support, an elastic part, a pressure rod and a guide rod.
