Express bag packaging machine

Abstract

The invention discloses an express bag packaging machine. A conveying mechanism of the express bag packaging machine is arranged in the mode that a winding roller set is matched with a sensor, expressbags with a certain length can be pre-stored in the winding roller set, the position change of the winding roller set is sensed by the winding roller set, and feeding of a front-back mechanism is controlled; a sealing and cutting mechanism of the express bag packaging machine adjusts the separation position of a movable sealing and cutting piece and a fixed sealing and cutting piece and debugs the size of the sealing and cutting stroke through the arrangement of the sensor in an adjusting mechanism; a bag dragging mechanism is arranged to drag the express bags and objects, and damage to the objects and the express bags is avoided; and the production efficiency of the express bag packaging machine is guaranteed on the whole, and effective protection on materials is achieved.

Description

technical field [0001] The invention relates to the field of packaging machinery, in particular to an express bag packaging machine. Background technique [0002] In the prior art, the courier bag packaging machine is used to transport the courier bags that have been basically formed. The delivery mechanism of the courier bag packaging machine outputs a tube of courier bags individually and hangs them under the sealing and cutting mechanism. After the items are put in, the courier bag is sealed by the sealing and cutting mechanism, and the front and rear courier bags are torn apart by the sawtooth tear, and the courier falls down to complete the packaging. [0003] A tube of courier bags is placed at the input roller of the conveying mechanism. When discharging, the courier bag is wound around a number of winding rollers and output to the rubber roller group, and the rubber roller group clamps the courier bag for external output; The driving mechanism is set at each place t...

Problems solved by technology

[0004] The sealing and cutting mechanism seals by closing the two sealing and cutting parts. One sealing and cutting part is fixed and the other is movable. The existing method is that the movable sealing and cutting part needs to go back and forth to the maximum stroke every time it is sealed and cut. When placing items that are not so large When the separation distance is too large, it is not necessary. The maximum stroke back and forth increases the time required for the sealing and cutting process. When packaging large quantities of express delivery, the time spent each time is accumulated, and the overall time spent slows down the packaging efficiency.

[0005] Because it is necessary to adapt to the bagging of express bags of different specifications, the sealing and cutting mechanism is set to a certain height, so that when putting items into the express bag, the express bag will be pulled, which may cause the express bag to be uneven and affect the quality of sealing and cutting, or the express bag is jagged. After the tear is torn open, it will fall to a certain height. Even if the bottom is provided with a flexible material to undertake it, it will still be difficult to avoid damage to the items in the courier bag at a higher height.
