Description

Inflation film manufacturing machine change of lap receiving mechanism

[technical field]

The utility model relates to a kind of inflation film manufacturing machine, is specifically related to a kind of change of lap receiving mechanism of inflation film manufacturing machine.

[background technology]

Inflation film manufacturing machine is an equipment of producing plastic sheeting specially, and plastic sheeting expects that from blowing out to be molded into to become volume will carry out rolling through receiving mechanism.The inflation film manufacturing machine receiving mechanism of prior art, after collecting shaft is received full coiled strip volume, generally need manual work to take off this collecting shaft after; New collecting shaft is changed in manual work again, and said process all is to adopt manual work, and production efficiency is low; Labour intensity is big, so our company has designed a kind of change of lap receiving mechanism that can realize automatic change of lap; Though improved operating efficiency, complex structure; In addition, the pneumatic shearing device that during change of lap film is cut off will rotate owing to drive the Rodless cylinder of fly cutter cut-out; And inlet end is fixed, thus the method that adopts be, when the air inlet of the Rodless cylinder that rotates arrives and during the secured in alignment inlet end; Fixedly extend into air inlet before the inlet suction port of inlet end, so Rodless cylinder is connected source of the gas drive fly cutter film is cut off, inlet suction port withdraws from the air inlet of Rodless cylinder then; Rodless cylinder is able to rotate once more, and the disadvantage of said structure is, the Rodless cylinder air inlet and fixedly the inlet suction port of inlet end be difficult to aim at; To also having on time gas leakage in various degree; Gas leakage is serious or do not have aligning all can cause the Rodless cylinder akinesia, and fly cutter can't cut off film, can only shut down processing; The functional reliability of pneumatic shearing device is not high, and the change of lap rewinding can not be carried out smoothly.

[summary of the invention]

In view of the deficiency that background technology exists, the purpose of the utility model aims to provide a kind of simple in structure, can realize that the change of lap rewinding is full-automatic, the inflation film manufacturing machine change of lap receiving mechanism of pneumatic shearing device reliable operation.

The utility model is implemented through following technical scheme:

Inflation film manufacturing machine change of lap receiving mechanism comprises frame, rolling roller, winding motor and pneumatic shearing device, and the rolling roller is located at rotationally on the frame and is driven by winding motor; It is characterized in that: inflation film manufacturing machine change of lap receiving mechanism also includes roll-switching device; Roll-switching device comprises change of lap swivel plate and positioning disk, and the change of lap swivel plate is slidingly connected on rolling roller axle, and the rotation of change of lap swivel plate is by driven by motor; The outer rim of change of lap swivel plate is provided with stationary jaw and movable jaw; Movable jaw and change of lap swivel plate are articulated and connected, and movable jaw is provided with positioning roller, and positioning roller is by the rolling of leading of the spigot surface of positioning disk; The spigot surface of positioning disk has breach, and positioning disk fixedly installs; When the spigot surface rolling of positioning roller and positioning disk contacted, positioning roller formed fixed support to movable jaw, and when the rotation of change of lap swivel plate, movable jaw and stationary jaw transmit from depositing station collecting shaft together to the rolling station.

Technique scheme is simple in structure, and its operation principle is, when the collecting shaft A at the rolling station receives full coiled strip volume; PLC instruction driven by motor change of lap swivel plate rotates forward, and after the change of lap swivel plate turned an angle, positioning roller began to contact with the spigot surface rolling of positioning disk; So positioning roller forms fixed support to movable jaw, form draw-in groove between movable jaw and the stationary jaw, through draw-in groove will the collecting shaft B that does not carry out rewinding that deposits station be sent to the rolling roller directly over; Collecting shaft B is because the gravity effect is pressed on the rolling roller, and pneumatic shearing device cuts off the film that connects collecting shaft A simultaneously, along with the continuous rotation of rolling roller; Film begins on collecting shaft B, to carry out rolling, and then, driven by motor change of lap swivel plate continues to rotate forward; Movable jaw and stationary jaw will just transmit to the rolling station at the collecting shaft B of rolling together, and meanwhile, the collecting shaft A that receives full material volume is seen off at the rolling station stays the room; Near the rolling station time, the positioning roller disengaging contacts with the positioning disk spigot surface, and movable jaw stirs backward; After collecting shaft B is placed into the rolling station smoothly; The change of lap swivel plate is got back to original position, thereby realizes full automatic change of lap rewinding, enhances productivity.

Said pneumatic shearing device comprises fly cutter, Rodless cylinder and gas circuit assembly, and fly cutter is promoted film is carried out horizontal cut-out by Rodless cylinder, and Rodless cylinder is installed on the said change of lap swivel plate; The gas circuit assembly comprises interior cover, overcoat, end cap and end cap seal, and interior cover is located on the said rolling roller axle rotationally, outside overlapping in overcoat is located at rotationally; Overcoat is fixedly connected with the change of lap swivel plate, between the overcoat, between interior overcoat, forms the toroidal cavity of sealing in end cap and end cap seal are located at; Put in said and be provided with air inlet, air inlet is fixed, and puts outward and is provided with the gas outlet; Rotate with Rodless cylinder the gas outlet, and air inlet, gas outlet are connected through toroidal cavity.

The pneumatic shearing device of said structure; Through the setting of gas circuit assembly, air inlet is fixed, so just docking with the fixing inlet suction port of inlet end reliably, air inlet is connected; Then rotate with Rodless cylinder the gas outlet; Be connected so the gas outlet also can be docked with the air admission hole of Rodless cylinder reliably, just do not have misalignment and aim at the gas leakage problem, and gas circuit assembly sealing itself is reliable like this; So greatly improved the functional reliability of pneumatic shearing device, guaranteed carrying out smoothly of change of lap rewinding.
