Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment one:
A kind of film line, with reference to Fig. 1, including film transmission mechanism, film transmission mechanism includes that the 1st, frame all rotates
The rotation roller 3 being arranged in frame 1 and strainer 4, wherein, rotating roller 3 has several, and the both sides up and down of strainer 4
All existing and rotating roller 3, after film 2 passes through strainer 4, strainer 4 carries out tensioning to film 2.
With reference to Fig. 1, Fig. 3 and Fig. 4, strainer 4 includes tensioning frame 41 and idler roller 42, and wherein, tensioning frame 41 rotates and sets
Put in frame 1, tensioning frame 41 be additionally provided with rotating shaft 7, idler roller 42 is provided with the rotation hole 421 coordinating with rotating shaft 7,
Rotate on the sidewall of rotation hole 421 and be provided with the ball 9 abutting with rotating shaft 7, and if being provided with on the outer ring surface of idler roller 42
Dry elastic bumps 8.After assembling up idler roller 42, the rotational plane of idler roller 42 is flat with the rotational plane of tensioning frame 41
OK.
Seeing figures.1.and.2, being additionally provided with abutting part 5 in frame 1, this abutting part 5 includes that being arranged on frame 1 opens relatively
The abutting block 51 that the chute 52 of tight frame 41 side and sliding are arranged in chute 52, wherein, the depth direction of chute 52 and tensioning
The rotational plane of frame 41 is vertical, abuts block 51 and regulating wheel lays respectively at the both sides of tensioning frame 41 and frame 1 hinged place, and abut
The upper surface of block 51 is provided with the fixing groove 511 coordinating with tensioning frame 41, is coated with elastic layer 6 on the inwall of fixing groove 511,
This elastic layer 6 can be made for elastomeric material.When tensioning frame 41 is fixed by needs, slide block abuts block 51, makes solid
Determine groove 511 and be positioned at the surface of tensioning frame 41, at this time tensioning frame 41 with the side of idler roller 42 sagging after, its opposite side meeting
Upwards moving, thus tensioning frame 41 offseting with the sidewall of fixing groove 511, at this time tensioning frame 41 just cannot rotate existing
As tensioning frame 41 also would not contact with film 2.
The course of work: with reference to Fig. 1, Fig. 2 and Fig. 4, during coiled film 2, first on lift tensioning frame 41, make tensioning frame
41 are positioned at the top abutting block 51, at this time slide against block 51 towards the direction back to chute 52, so that abutting on block 51
Fixing groove 511 be positioned at the surface of tensioning frame 41；Unclamping tensioning frame 41, at this time tensioning frame 41 has the side of idler roller 42
Owing to the gravity of himself rotates down, and the opposite side of tensioning frame 41 can upwards move, thus is connected to the interior of fixing groove 511
On wall.Then film 2 is sequentially passed through several transfer rollers, but owing to tensioning frame 41 is connected to abut on block 51, therefore this
When tensioning frame 41 cannot naturally droop the position of its minimum point, i.e. now exist between idler roller 42 and film 2 certain away from
From idler roller 42 does not have any tension to film 2, and has lacked the tension of idler roller 42, at this time at winding
Can be lighter when film 2.
And after winding film 2, first on lift tensioning frame 41 so that tensioning frame 41 departs from fixing groove 511, then will support
Connect block 51 to promote in chute 52, make abutting block 51 be entirely located in chute 52；Then tensioning frame 41, tensioning frame 41 meeting are unclamped
Owing to himself Action of Gravity Field naturally droops on film 2, thus complete the tensioning to film 2.
Embodiment two:
A kind of film line, with reference to Fig. 5 and Fig. 6, the present embodiment is with the difference of embodiment one: in the present embodiment
Abutting part 5 includes the thread groove 54 being arranged on relative tensioning frame 41 side of frame 1 and coordinates with thread groove 54 and can be with tensioning frame
The screw rod 53 that 41 offset, the depth direction of thread groove 54 is vertical with the rotational plane of tensioning frame 41, is provided with in thread groove 54
Elastic component, this elastic component is turriform spring 10, the two ends of turriform spring 10 respectively with chute 52 bottom and screw rod 53 offset.
During coiled film 2, it is only necessary to twist screw rod 53, screw rod 53 entirety is made to move out, so that screw rod
The part of 53 is positioned at tensioning frame 41, at this time unclamps tensioning frame 41, and tensioning frame 41 can offset with screw rod 53 such that it is able to effectively
Tensioning frame 41 of avoiding offset with film 2, and now turriform spring 10 is in compressive state, and it can produce one to screw rod 53
Thrust, thus prevent screw rod 53 from occurring rotating；And after winding film 2, then twist screw rod 53, make screw rod 53 and tensioning frame 41 points
From at this time tensioning frame 41 can naturally droop down, and idler roller 42 now can offset with film 2, thus realizes opening to film 2
Tightly.
This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model
The present embodiment can be made after reading this specification by field technique personnel as required does not has the modification of creative contribution, but
As long as all being protected by Patent Law in right of the present utility model.
