Abstract
The utility model relates to a film rolling and expanding shaft device, in particular to a mechanical film rolling and expanding shaft device. The mechanical film rolling and expanding shaft device comprises a thrusting device and a scroll connected with the thrusting device, wherein the inside of the scroll is provided with a central shaft; the central shaft is provided with two annular bosses; the upper end and the lower end of each annular boss are connected with mechanical expansion pins; the tail end of the scroll is provided with a shaft plug; the tail end of the central shaft is connected with a return spring; and the return spring is supported against the shaft plug. The mechanical film rolling and expanding shaft device disclosed by the utility model has the advantages of reasonable structure, convenience in use and good economic benefit, the fixing effect is good due to the fact that a pipe core is ejected from inside to outside by the expansion pin, and the manpower cost is lowered due to automatic action.
Description
Technical field
The utility model relates to a kind of film volume swelling shaft device, is specifically related to a kind of mechanical type film volume swelling shaft device.
Background technology
Need film is twisted on tube core in the film production process.Due to certain space being arranged between tube core and spool, to rotate for guaranteeing that tube core can be synchronizeed with rotating shaft, traditional mode is to hammer into chock between tube core and spool, choke tube core by chock, this fixed form working strength is large, and easily skids, fixing weak effect, tube core is easily destroyed.
The utility model content
According to the deficiency in above technology, the technical problems to be solved in the utility model is: a kind of good fixing effect is provided, implements mechanical type film volume swelling shaft device easily.
The mechanical type film volume swelling shaft device that the utility model provides, comprise head into device with the spool that heads into device and be connected, center shaft is installed in spool, two annular boss are installed on center shaft, the two ends up and down of annular boss connect the mechanical type expansion pin, and the end of spool is provided with the axle plug; The center the tip of the axis connects retracing spring, and retracing spring withstands on axle beyond the Great Wall.
The pin face of described mechanical type expansion pin leans out spool, and the bottom surface of expansion pin is provided with two indents, and a side of two indents is the inclined-plane, and two annular boss insert respectively in these two indents.
Described mechanical type expansion pin is four, is evenly distributed on spool, and the bottom of two relative mechanical type expansion pins connects by spring.
The beneficial effect that the utility model has is, and is rational in infrastructure, easy to use, outwards withstands tube core by expansion pin by inside, good fixing effect, and be auto-action, reduce human cost, have good economic benefit.
Description of drawings
Fig. 1 is the utility model structural representation;
In figure: 1, head into device; 2, spool; 3, center shaft; 4, mechanical type expansion pin; 5, annular boss; 6, retracing spring; 7, axle plug; 8, spring; 9, indent.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Mechanical type film volume swelling shaft device as shown in Figure 1, comprise head into device 1 with the spool 2 that heads into device 1 and be connected, center shaft 3 is installed in spool 2, two annular boss 5 are installed on center shaft 3, the two ends up and down of annular boss 5 connect mechanical type expansion pin 4, and the end of spool 2 is provided with axle plug 7; The end of center shaft 3 connects retracing spring 6, and retracing spring 6 withstands on axle plug 7.The pin face of mechanical type expansion pin 4 leans out spool 2, and the side that the bottom surface of expansion pin is provided with 9, two indents 9 of two indents is the inclined-plane, and two annular boss 5 insert respectively in these two indents 9.
Mechanical type expansion pin 4 is four, is evenly distributed on spool, and the bottom of two relative mechanical type expansion pins connects by spring 8.
During use, head into device 1 center shaft 3 is inwardly pressed on the top, center shaft 3 overcomes the elastic force of retracing spring 6, drives annular boss 5 and moves inward.And then annular boss 5 moves along the inclined-plane mechanical type expansion pin 4 outwards ejected, and tube core is withstood, and completes the volume membrane process.The volume film heads into device 1 after completing and lets out power, also completes under spring 8 pulls and resets in the mechanical type expansion pin 4 that resets of center shaft 3 under the effect of retracing spring 6, and loosening the taking off of tube core gets final product.
Claims (3)
