Description

A kind of roll wrapper adopting entire volume film to pack

Technical field

The present invention relates to facial tissue packer mechanical field, is more particularly a kind of roll wrapper adopting entire volume film to pack.

Background technology

The features such as facial tissue packer replaces Traditional Man packaging, has speed fast, packaging neat appearance, had both saved manpower and had turn improved production efficiency.But with the quickening pace of modern life, people are also increasing to the demand of paper handkerchief, especially paper in reel, be that people's life requirement amount is maximum; The requirement of people to paper in reel is not only the quality of paper, also to the appearance package of paper in reel, certain requirement is housed.In order to meet the demand of people, packaging efficiency and the Accuracy of Packaging of paper in reel just must be improved.

State Intellectual Property Office was on February 22nd, 2006, disclosing a publication number is CN1736801A, name is called the patent of invention of " a kind of materials packing machine ", a kind of materials packing machine of this patent of invention, comprise the shaping sealing device of film feeder, feed arrangement and packaging film, described film feeder comprises all film mechanisms; The shaping sealing device of described packaging film comprises the packaging film supporting plate be located on support, and this supporting plate is provided with the material through hole that shape and size all match with material to be packaged; With the packaging film former be located at above packaging film supporting plate material through hole; With the material location clamping part be located at above packaging film former and material propulsion component, the running direction of material location clamping part and material propulsion component is perpendicular; With hand and is packed for the seal plate of seal material bottom surface packaging film in the one group of material bottom surface be between packaging film former and material clamping part; And one material can be delivered to below packaging film supporting plate material location clamping part material jacking parts.

This patent of invention first packaging film is cut into block by certain specification size, then the packaging film of well cutting is delivered on the through hole of supporting plate, then by jacking parts, material is pushed to clamping part place, material location, in the process pushed, material passes through through hole, and by the packaging film jack-up on through hole, pass through material channel, packaging film is made to be coated on material end face and two ends, when material is transported to clamping part place, material location, material clamps by material location clamping part, then pack hand and packing box heat-seal is carried out to the packaging film of material bottom surface, again pin forming is carried out to material both sides afterwards, complete the packaging of whole material.

There is following problem in above-mentioned a kind of material packing machine of the prior art:

1, be all first entire volume film is cut into individual film to the packaging of the materials such as paper handkerchief in prior art, then the corresponding single material of individual film is packed, this manner of packing is that packaging process is lost time, and packaging efficiency is low discontinuously solely to single material package.

2, the paper handkerchief manner of packing of prior art, the corresponding single material package of individual film, is difficult to locate packaging film, pattern on packaging film or decorative pattern can not be navigated on the specific position of material, make in subsequent packages process, there is skew in pattern or decorative pattern, it is attractive in appearance that impact is packed.

3, existing manner of packing adopts material jacking or the mode that falls in film former, this manner of packing has certain requirement to package speed, jacking or the whereabouts of packing materials can not exceed setting speed, after exceeding setting speed, this kind of manner of packing can not ensure the regularity of material, can not pack the precision of packaging film packing materials, be unfavorable for improving packaging efficiency, packaging efficiency is low simultaneously.
