Close the film machine
The present invention relates generally to the package packing machine field, relates in particular to a kind of film machine that closes that is used for the plastic film packing.
The chemical of plastic film packaging product such as ham sausage, quick-frozen food and other liquid state, paste article, high medium viscosity normally carries out on the film machine that can produces closing, and closes the film machine and is made up of the equipment of multi-platform combined action; When producing; Plastic film carries out crimping through the collar former, and is bonding firmly by the glue spreading apparatus gluing behind the crimping, then carries out can; Be delivered to rotation shutoff device cut-outs of checking card of checking card by film conveying device again after the can, thus the whole production of completion from the plastic film to the finished product.
There are shortcomings such as complicated operation, preparation and operating cost height in the existing film machine that closes, and its structure and layout remain further to be optimized, and are embodied in the following aspects.
1, existingly closes the device for squeezing glue complex structure in the film machine; Cost of manufacture is high: at first, the gum outlet of device for squeezing glue (screw rod gelatin extrusion machine) through a joint heat-preserving hose with go out adhesive dispenser and link to each other, the length of heat-preserving hose is approximately 1200mm; And it has special requirements of making, and cost of manufacture is higher; Be fixed on the up-down mechanism and go out adhesive dispenser; When gluing; Up-down mechanism drives out adhesive dispenser and moves downward and carry out gluing, and the plastic squeeze mouth that goes out adhesive dispenser for ease inserts in the film and carries out gluing, also is provided with a cover and colludes the film that film mechanism is located at volume on the passage and collude out; When gluing not, the up-down mechanism upward movement makes the plastic squeeze mouth away from passage and since gluing during with gluing not the plastic squeeze action all can not stop; Can only speed be slowed down; Otherwise the plastic squeeze mouth is stopped up, and this just also need be provided with and connect gluing mechanism, and the existing gluing mechanism that connects connects glue through a cover rotating mechanism driving upset; Its structure is comparatively complicated, has increased productive costs and debugging difficulty.
2, material is driven by two synchronous tape drive mechanisms in the existing clapper die spotting press, and two synchronous tape drive mechanisms only drive through an electric machine control, its complex structure, and easy break-down, installation and debug difficulties, running noises is big, is prone to jump tooth, and stabilization of equipment performance is bad.
3, existingly close the moulding device inefficiency in the film machine: existing to close the moulding wheel that is used for moulding in the film machine be columniform; The passage top of fitting with moulding wheel is scabbled makes it to have facet, carries out moulding through plane contact moulding wheel then, yet; For the charging machine of minor diameter, there is a bigger difficult problem always; Be exactly how to improve production capacity, and the bottleneck that improves production capacity is exactly the size and the length of passage internal diameter, the size that is limited by powder stick itself because of the external diameter and the collar former of passage; Under the situation that external diameter can not strengthen, only add large diameter and just might improve production capacity; But it is thick that the aforementioned moulding mode that passage top is scabbled causes the tube wall of passage to do so that the top of passage when being scabbled the tube wall body can not cut and worn, be exactly to make the internal diameter of passage littler and do thick tube wall under the external diameter unmodified prerequisite with regard to the result; The carrying capacity that this has just influenced the can material greatly also greatly reduces the production capacity and the production efficiency of closing the film machine.
4, include collar former and passage in the existing building mortion that closes the film machine, but collar former and passage be separately fixed on the riser, install and change and need operate one by one, the installing and replacing inconvenience, efficient is not high.
5, the existing film conveying device that closes the film machine and the rotation speed synchronization device of checking card between the shutoff device is to drive the eccentric wheel rotation that is fixed on the S. A. through the swing arm rotating mechanism; Variation through distance between sensor sensing and the eccentric wheel comes feedback speed again; The swing arm rotating mechanism whenever rotates to an angle, and the distance between eccentric wheel and the sensor has certain variation, and there is the slower shortcoming of speed of response in the eccentric reforming unit of this kind; When carrying out high-speed production, its synchronous effect is bad.
6, in addition; Close in the manufacturing line of film can existing, connect film machine, automatic deviation rectifying device, close the film machine basically along the linear sequence layout, the device space takies very big; It is bigger with the spacing of closing the film machine to connect the film machine, and inconvenient operating personal carries out control operation simultaneously to two equipment.
