Abstract
The invention discloses a novel square-bottom paper bag forming method. The forming process comprises the following steps of 1 unwinding, 2 barrel forming, 3 impressing, 4 primary cutting off, 5 bottom opening, 6 bottom gluing, 7 secondary cutting off and 8 bottom combining. Paper barrels are kept integrally and continuously output before the bottom combining procedure, and therefore no conveying speed difference needs to be set for conveying speed of the paper barrels between the adjacent procedures. The conveying speed of the paper barrels in the process of impressing, primary cutting off, bottom opening, bottom gluing, secondary cutting off and bottom combining is set to be maximum, and the paper bag forming efficiency is greatly improved.
Description
Technical field
The present invention relates to paper bag and make field, be specifically related to a kind of paper bag forming method.
Background technology
As everyone knows, paper is a kind of resource of recyclable recycling.The raw material mainly string of papermaking, except containing except cellulose, hemicellulose, the large main component of lignin three in raw material, still has the component that other content are less, as resin, ash etc.In addition the auxiliary elements such as sodium sulphate are also had.Except string in paper, also need to add different fillers according to different paper wood.It is oil that normally used polybag makes raw material used by polyethylene, and oil has been our energy in short supply.By contrast, the raw materials for production of paper bag are trees, are a kind of renewable resources.The degradable itself had, the feature of recoverable have sticked green-ticket naturally.
In prior art, see Fig. 1, as shown in legend wherein, the making of paper bag mainly comprises following several steps:
(1), unreel, paper roll 110 is placed on paper frame, and paper roll 110 unreels, continuous print output raw material paper 111;
(2) cylinder is become, raw material paper 111 continuous print input Zhe Tong mechanism, raw material paper 111 carries out in folding position being folded into cylinder, continuous print exports the paper web flattened, and paper web comprises the paper web front surface A 121 at top layer, the paper web front B122 at bottom and is clipped in the paper web side 123 of the doubling between paper web front surface A 121 and paper web front B122;
(3) cut off, above-mentioned paper web continuous print input shut-off mechanism, paper web cuts off in off-position successively, exports some paper web sections 130;
(4) impression; Some paper web sections 130 input creasing mechanism successively, and paper web section 130 carries out impression at the first Indentation position 141 and the second Indentation position 142 successively, exports some bands paper web section 140 creasy successively;
(5) end is opened; Some bands paper web section 140 creasy inputs Kai Di mechanism successively, and some bands paper web section 140 creasy carries out out the end opening position, the end, exports some paper web sections 150 opening the end successively;
(6) bottom gluing, some paper web sections 150 opening the end input bottom gumming mechanism successively, and some paper web sections 150 opening the end carry out gluing in gluing position successively, export the paper web section 160 of some gluings;
(7) close the end, the paper web section 160 of some gluings inputs Zhe Di mechanism successively, and the paper web section 160 of some gluings is carried out at the bottom of conjunction in conjunction position, the end, exports the paper web section 170 at the bottom of some conjunctions;
(8) shaping, export several shaping paper bags 180 successively.
Raw material paper is successively through unreeling, become cylinder and export multiple independent paper web section successively after cutting off, each paper web section enters creasing mechanism successively, Kai Di mechanism, bottom gumming mechanism and Zhe Di mechanism, finally shaping, when cutting off, very close to each other between adjacent paper web section, in order to ensure follow-up impression, open the end, bottom gluing and close in end process, can not influence each other between adjacent paper web section, therefore follow-up impression, open the end, bottom gluing and close in end process, between adjacent operation, the transmission speed of paper web must arrange transmission speed difference, make to form gap between the paper web section of adjacent operation, impression, open the end, bottom gluing and the transmission speed of paper web of closing in end process must constantly increase progressively, like this, the speed of preceding processes must be reduced as far as possible, the paper bag efficiency of whole paper bag will be affected, in addition, multiple operation mechanism is set, and be generally greater than the length of paper web section due to the distance between adjacent operation, therefore need to arrange live-roller between adjacent operation, like this, the complicated integral structure of paper bag machine, difficult in maintenance.
Summary of the invention
