Abstract
The utility model discloses a kind of plastic-box packaging machine, comprise closing device, described closing device limit is provided with mouth expanding apparatus, described mouth expanding apparatus comprises pair of support rods, and described strut bar is distributed in for sealing plastic bag both sides, before plastic bag sealing, described strut bar enters after in plastic bag along plastic bag opening, respectively to two lateral movements of plastic bag, the both sides of supporting plastic bag, make plastic bag top tighten not fold; Wrapping machine of the present utility model achieves in plastic bag sealing process, and sack is in tight state all the time, avoids sack to produce dislocation, fold, improves packaging quality.
Description
Technical field
The utility model relates to a kind of wrapping machine, specifically a kind of company's volume plastic-box packaging machine that continuously, automatically can carry out packing.
Background technology
Packaging product relates to the every aspect of daily life, the melon seeds eaten at ordinary times, peanut, the clothing bought, the major parts such as the article of post office mailing all adopt packaging bag independent packaging, shopping online such as prevailing at present, clothing adopts plastic bag to pack mostly, then pays express delivery and transports.
When packing plastic bag, there is a very large problem is seal often to there is fold, and the existence of sealing fold drastically influence the quality of packaging.The major cause that sealing exists fold is: be filled with article because plastic bag is in-built, plastic bag is no longer smooth, when enclosed mechanism seals it; sealing often can produce fold, affects the attractive in appearance of plastic bag packaging, time serious; fold is comparatively large, can not seal completely, cause packaging quality.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of plastic-box packaging machine, and the sealing of this wrapping machine to plastic bag is attractive in appearance, can not produce fold.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of plastic-box packaging machine, comprise closing device, described closing device limit is provided with mouth expanding apparatus, described mouth expanding apparatus comprises pair of support rods, and described strut bar is distributed in for sealing plastic bag both sides, before plastic bag sealing, described strut bar enters after in plastic bag along plastic bag opening, respectively to two lateral movements of plastic bag, the both sides of supporting plastic bag, make plastic bag top tighten not fold.
Described strut bar is arranged on cylinder, and cylinder drives strut bar to swing and enters in plastic bag along plastic bag opening, and the both sides of supporting plastic bag.
The strut bar of mouth expanding apparatus enters after in plastic bag along plastic bag opening, and strut bar is respectively to two lateral movements of plastic bag, and the both sides of supporting plastic bag, make plastic bag top tighten not fold.
Strut bar enters after in plastic bag, enters the length of the strut bar of plastic bag opening no more than seal location line, otherwise will affect sealing operation.
Two rear flank of they sup-port plastic bag, plastic bag top is tightened does not have fold, and now the closing device of wrapping machine carries out sealing operation to the opening part of plastic bag, and like this, sealing would not occur buckling problems.
Wrapping machine of the present utility model achieves in plastic bag sealing process, and sack is in tight state all the time, avoids sack to produce dislocation, fold, improves packaging quality.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Embodiment 1
Individual plastic bag is sealed: arrange mouth expanding apparatus on the closing device limit of wrapping machine, mouth expanding apparatus comprises pair of support rods 20, and strut bar 20 drives swing by cylinder 19.Strut bar 20 is distributed in for sealing plastic bag both sides, the specifically both sides of plastic bag opening, and before plastic bag sealing, strut bar 20 enters after in plastic bag along plastic bag opening, respectively to two lateral movements of plastic bag in plastic bag opening, and the both sides of supporting plastic bag.
Strut bar 20 enters after in plastic bag, and the length entering the strut bar 20 of plastic bag opening, no more than seal location line 30, makes plastic bag top tighten not fold.
Two rear flank of they sup-port plastic bag, plastic bag top is tightened does not have fold, and now the closing device of wrapping machine carries out sealing operation to the opening part of plastic bag, and like this, sealing would not occur buckling problems.
Embodiment 2
Seal connecting volume plastic bag: same, arrange mouth expanding apparatus on the closing device limit of wrapping machine, mouth expanding apparatus comprises pair of support rods, and strut bar is swung by air cylinder driven.Strut bar is distributed in for sealing plastic bag both sides, the specifically both sides of plastic bag opening, before to a plastic bag sealing on company's volume plastic bag, strut bar enters after in plastic bag along the tear line 31 of plastic bag, respectively to two lateral movements of plastic bag in plastic bag opening, the both sides of supporting plastic bag.
Strut bar 20 enters after in plastic bag, and the length entering the strut bar 20 of plastic bag opening, no more than seal location line 30, makes plastic bag top tighten not fold, makes plastic bag top tighten not fold.
Two rear flank of they sup-port plastic bag, plastic bag top is tightened does not have fold, and now the closing device of wrapping machine carries out sealing operation to the opening part of plastic bag, and like this, sealing would not occur buckling problems.
Above-described embodiment limits the utility model never in any form, and the technical scheme that the mode that every employing is equal to replacement or equivalent transformation obtains all drops in protection domain of the present utility model.
