Description

Synchronous non-woven fabric compounded machine unwinding device

Technical field

The utility model relates to a kind of synchronous non-woven fabric compounded machine unwinding device.

Background technology

When in existing technology, if non-woven fabric compounded machine unreels asynchronous all right cause the tension force of two-layer nonwoven or internal stress inconsistent, can cause like this having after compound the generation of the phenomenons such as unfairness, fold.In order to ensure two asynchronous motors that synchronously often adopt that unreel, control respectively two mandrels, then regulate motor synchronous, because motor individuality exists certain difference, be difficult to reach rotating speed in full accord, Complete Synchronization in the time of therefore cannot guaranteeing to unreel.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of synchronous non-woven fabric compounded machine unwinding device, uses a motor to control two mandrels simultaneously, guarantees the true synchronization of mandrel.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: synchronous non-woven fabric compounded machine unwinding device, comprise supporting frame, upper driven member, lower driven member, upper mandrel body, lower mandrel body, driving tooth wheel body and motor, on described, lower driven member structure is identical, parallel interval arranges, on described, lower driven member all has center shaft, described upper driven member is body, described body one end is closed end, described center shaft is positioned at described closed end outside, described center shaft is fixed on support frame as described above body, on described, lower driven physical efficiency is rotated centered by described center shaft, on described body lateral surface, there is a circle external tooth,

Described upper and lower mandrel body is connected with described upper and lower driven member detouchable respectively;

Described driving gear body is positioned between described upper and lower driven member, described driving tooth wheel body respectively with described upper and lower driven member on external tooth engagement, rotating shaft on described motor and described driving tooth wheel body are fixed, described in described driven by motor, driving tooth wheel body rotates, and described motor is fixed on support frame as described above body.

Preferably, described upper and lower mandrel body structure is identical, and the lateral surface of described upper mandrel body one end has one section of external spline teeth;

Described upper driven member inwall has the inner spline gear with described external spline teeth adaptation, and described inside and outside spline tooth engagement makes described upper mandrel body be connected with described upper driven member detouchable.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, only use a motor just can control two mandrels simultaneously, eliminated mechanical error, guarantee the precise synchronization unreeling.

Accompanying drawing explanation

Fig. 1 is that integral structure master of the present utility model looks schematic diagram;

Fig. 2 is upper driven member structural representation;

Fig. 3 is upper mandrel body structure schematic diagram;

In figure: 1-supporting frame; 2-motor; 3-machine shaft; The upper driven member of 4-; Driven member under 5-; The upper mandrel body of 6-; Mandrel body under 7-; 8-driving tooth wheel body; 9-external tooth; 10-center shaft; 11-inner spline gear; 12-external spline teeth.

The specific embodiment

As shown in the figure, the utility model provides a kind of synchronous non-woven fabric compounded machine unwinding device, comprise supporting frame 1, upper driven member, lower driven member 4, 5, upper mandrel body, lower mandrel body 6, 7, driving tooth wheel body 8 and motor 2, on, lower driven member 4, 5 structures are identical, parallel interval arranges, on, lower driven member 4, 5 all have center shaft 10, upper driven member 4 is body, body one end is closed end, center shaft 10 is positioned at closed end outside, center shaft 10 is fixed on supporting frame 1, on, lower driven member 4, 5 can rotate centered by center shaft 10, on body lateral surface, there is a circle external tooth 9,

Upper and lower mandrel body 6,7 is connected with upper and lower driven member 4,5 detouchables respectively;

Driving tooth wheel body 8 is between upper and lower driven member 4,5, driving tooth wheel body 8 respectively with upper and lower driven member 4,5 on external tooth 9 engagement, rotating shaft 3 on motor 2 is fixing with driving tooth wheel body 8, and motor 2 drives driving tooth wheel body 8 to rotate, and motor 2 is fixed on supporting frame 1.

Upper and lower mandrel body 6,7 with the concrete annexation of upper and lower driven member 4,5 is: upper and lower mandrel body 6,7 structures are identical, and the lateral surface of upper mandrel body 6 one end has one section of external spline teeth 12;

Upper driven member 4 inwalls have the inner spline gear 11 with external spline teeth 12 adaptations, and inside and outside spline tooth 11,12 engagements make mandrel body 6 be connected with upper driven member 4 detouchables.

The working process of this example: motor 2 rotates and makes 8 rotations of driving tooth wheel body, thereby drive upper and lower driven tooth wheel body 4,5 to rotate, because inside and outside spline tooth 11,12 engagements are synchronously rotated upper and lower mandrel body 6,7, with this, guarantee that a motor controls upper and lower mandrel body 6,7 simultaneously and synchronously unreel, guaranteed the precise synchronization unreeling.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
