The specific embodiment

First sight is shown in Figure 1; Disclose the block diagram of the utility model preferred embodiment; And cooperate Fig. 2 to Fig. 4 to explain that the utility model transmits the tenslator of continuity glued membrane; Comprise a bearing 1, one preceding back-up roller 2, one a back back-up roller 3 and a compacting cylinder 4; This bearing 1 has two symmetrical

bogie side frame

1a, 1b, and the both-end of said

bogie side frame

1a, 1b forms an input end 11 and a mouth 12 of glued membrane 8 respectively, and said input end 11 is positioned on the mobile route of glued membrane 8 with mouth 12; Should before back-up roller 2 hub settings between the said bogie side frame 1a of

input end

11,1b; These back back-up roller 3 hub settings are between the said bogie side frame 1a of

mouth

12,1b; And compacting cylinder 4 is along the vertical direction active configuration in preceding back-up roller 2 and on the bearing 1 between the back-up roller 3 of back; And between said

bogie side frame

1a, 1b, cause compacting cylinder 4 to be positioned on the mobile route of glued membrane 8; In this enforcement, hub setting has the feed cylinder 5 of a glued membrane between the said bogie side frame 1a of

input end

11,1b more, and before making back-up roller 2 feed cylinder 5 with suppress between the cylinder 4, and bogie side frame 1a be provided with one can drive feed cylinder 5 motor 51.

In a concrete enforcement; For compacting cylinder 4 can between said

bogie side frame

1a, 1b, be moved along vertical direction is stable; Said bogie side frame 1a, the last corresponding position of 1b are provided with a guide rail 6 (cooperating Fig. 5 to shown in Figure 7) along vertical direction separately; This guide rail 6 is between preceding back-up roller 2 and back back-up roller 3; And the sliding slide 61 of establishing on the guide rail 6, an axostylus axostyle 41 hub settings of this compacting cylinder 4 are suppressed cylinder 4 along with said slide 61 slides along guide rail 6 toward vertical directions and make between said slide 61.In addition; The last active configuration of

bogie side frame

1a, 1b of these guide rail 6 nearly edge has a stop part 62; This stop part 62 is actually along the vertical direction that moves of compacting cylinder 4 and is slidedly arranged in the last sliding sleeve 63 of this

bogie side frame

1a, 1b, and makes stop part 62 can get involved and break away from the mobile route of slide 61, with backstop and discharge slide 61 and move; And stop part 62 tops have an ear 621, can stir ear 621 and move stop part 62 via staff.

In another concrete enforcement; For compacting cylinder 4 can during moving between said bogie side frame 1a, the 1b, be rolled; Said bogie side frame 1a, the last corresponding position of 1b separately along vertical direction be provided with one be parallel to guide rail 6 tooth bar 7 (cooperating Fig. 5) to shown in Figure 7; This tooth bar 7 is between preceding back-up roller 2 and back back-up roller 3; And engagement one gear 71 on the tooth bar 7, the axostylus axostyle 41 of this compacting cylinder 4 is fixed between the axle center of said gear 71, and makes compacting cylinder 4 along with said gear 71 rolls along vertical direction.In fact; Said bogie side frame 1a, the last corresponding position of 1b are provided with a bar shaped seat 60 along vertical direction separately; And bar shaped seat 60 is at back and front supporting cylinder 2, between 3, and this guide rail 6 is formed on the bar shaped seat 60, and this tooth bar 7 is located at bar shaped seat 60 sides; And axostylus axostyle 41 passes gear 71 axle center, and hub setting is on slide 61.

Form according to above-mentioned member; Can supply to implement according to this utility model; Can stir stop part 62 before using earlier and get involved the mobile route of slide 61, move, can become glued membrane 8 covers of cylindric kenel to organize on feed cylinder 5 (as shown in Figure 8) a bundle simultaneously with backstop slide 61; And driving feed cylinder 5 via motor 51 disengages glued membrane 8 toward mouth 12 directions from input end 11 continuously; And back-up roller 2, compacting cylinder 4 and back back-up roller 3 before the glued membrane 8 that disengages is continuously passed through in regular turn, make glued membrane 8 be set around before back-up roller 2 and back back-up roller 3 end faces, and be set around compacting cylinder 4 bottom surfaces; Subsequently; Stir the mobile route that stop part 62 breaks away from slide 61, move (as shown in Figure 9) to discharge slide 61 toward the below, and make compacting cylinder 4 press down glued membrane 8 with the mode of free-falling body and rolling; Cause the weight of glued membrane 8 loads compacting cylinder 4 and keep tensioned state, with the tension force of control glued membrane 8; During glued membrane 8 continuous transmissions, this compacting cylinder 4 can be accepted glued membrane 8 carryings and fluctuate with roll mode, impels glued membrane 8 to keep tensioned states.

In view of the above, this compacting cylinder 4 is with free-falling body form configuration, and possesses gravity compacting continuity glued membrane 8, can effectively control the tension force of said glued membrane 8, so promote said glued membrane 8 shape and area cut precision.

More than explanation is just illustrative as far as the utility model; And nonrestrictive, those of ordinary skills understand, under the situation of spirit that does not break away from claim and limited and scope; Can make many modifications, variation or equivalence, but all will fall within the protection domain of the utility model.
