Description
Technical field
The utility model relates to a kind of multilayer complex films bag-making inner film tension control system.
Background technology
Existing multilayer complex films Bag Making Machine, is generally to adopt multiple discharging frames, and each discharging frame has two material volumes, after tension bracket, draws together bag.Due to the draftability different (inner membrance is thinner) of inner membrance and adventitia, inner membrance is than adventitia easier stretcher strain in the time drawing, after longitudinal sealing and horizontal sealing, inner membrance shrinks larger than adventitia, sack there will be fold, causes that heat seal strength is difficult to ensure, produces the problems such as bottom pour ladle.In order to address the above problem, the utility model provides a kind of multilayer complex films bag-making inner film tension control system, and this device can arbitrarily regulate the tension force of inner membrance within the specific limits.
Utility model content
In order to address the above problem, the utility model provides a kind of multilayer complex films bag-making inner film tension control system.
The utility model solves the technical scheme that its technical problem adopts:
A kind of multilayer complex films bag-making inner film tension control system, be arranged between tension bracket and discharging frame, comprise some inner membrance traction servomechanism installations and a control system, each inner membrance traction servomechanism installation draws two-layer inner membrance separately, and the hauling speed of each inner membrance traction servomechanism installation can control to adjust by control system.
Described each inner membrance traction servomechanism installation all comprises a frame, carry-over pinch rolls group and a servomotor, and carry-over pinch rolls are rotating to be arranged in frame, and driven by servomotor carry-over pinch rolls rotate, and inner membrance passes through in the middle of two carry-over pinch rolls.
The quantity of described inner membrance traction servomechanism installation is set to two, be respectively the first inner membrance traction servomechanism installation, the second inner membrance traction servomechanism installation, these two inner membrance traction servomechanism installations are arranged in order to tension bracket along discharging frame, the first inner membrance traction servomechanism installation is for drawing the innermost layer inner membrance of sack, the second inner membrance traction servomechanism installation is for drawing the inferior internal layer inner membrance of sack, innermost layer inner membrance after the first inner membrance traction servomechanism installation traction between twice internal layer inner membrance, and together with inferior internal layer inner membrance by the second inner membrance traction servomechanism installation.
The beneficial effects of the utility model are: adopt the utility model of said structure independently to draw every layer of inner membrance of multilayer complex films sack, by control system, the tension force of inner membrance is accurately controlled simultaneously, realize inner membrance and draw bag with less tension force together with adventitia, ensure the uniformity of interior adventitia stretcher strain, bag appearance looks elegant, heat seal strength is even.The utility model is simple in structure, can on traditional multilayer complex films Bag Making Machine basis, increase the utility model and can reach the effect that bag quality significantly promotes.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is principle schematic of the present utility model;
Fig. 3 is the schematic top plan view of Fig. 1.
Detailed description of the invention
With reference to Fig. 1～Fig. 3, the utility model is a kind of multilayer complex films bag-making inner film tension control system, be arranged between tension bracket 1 and discharging frame 2, comprise some inner membrance traction servomechanism installations and a control system, each inner membrance traction servomechanism installation draws two-layer inner membrance separately, and the hauling speed of each inner membrance traction servomechanism installation can control to adjust by control system.Each inner membrance traction servomechanism installation all comprises a frame, carry-over pinch rolls group and a servomotor, and carry-over pinch rolls are rotating to be arranged in frame, and driven by servomotor carry-over pinch rolls rotate, and inner membrance passes through in the middle of two carry-over pinch rolls.
Adopt the utility model of said structure independently to draw every layer of inner membrance of multilayer complex films sack, by control system, the tension force of inner membrance is accurately controlled simultaneously, realize inner membrance and draw bag with less tension force together with adventitia, ensure the uniformity of interior adventitia stretcher strain, bag appearance looks elegant, heat seal strength is even.The utility model is simple in structure, can on traditional multilayer complex films Bag Making Machine basis, increase the utility model and can reach the effect that bag quality significantly promotes.
As shown in the figure, in the present embodiment, because the sack of manufacturing is six layers of composite membrane sack, therefore the quantity of inner membrance traction servomechanism installation is set to two, be respectively the first inner membrance traction servomechanism installation 3, the second inner membrance traction servomechanism installation 4, these two inner membrance traction servomechanism installations are arranged in order to tension bracket 1 along discharging frame 2, the first inner membrance traction servomechanism installation 3 draws for the innermost layer inner membrance to sack, the second inner membrance traction servomechanism installation 4 draws for the inferior internal layer inner membrance to sack, discharging frame 2 includes two inner membrance discharging frames and an adventitia discharging frame, in the middle of adventitia discharging frame is positioned at, two inner membrance discharging frames are positioned at adventitia discharging frame both sides, two inner membrance discharging frames and an adventitia discharging frame are isosceles triangle and distribute, each discharging frame divides upper and lower two discharging rolls, totally 6 discharging rolls blowing simultaneously, film on two inner membrance discharging frames enters respectively the first inner membrance traction servomechanism installation 3, the second inner membrance traction servomechanism installation 4 through doubling-up device, innermost layer inner membrance after the first inner membrance traction servomechanism installation 3 tractions between twice internal layer inner membrance, and together with inferior internal layer inner membrance by the second inner membrance traction servomechanism installation 4.Be isosceles triangle distribute two inner membrance discharging frames and an adventitia discharging frame non-interference, change when film and use small-sized hand-operated fork truck, without hanging device; And space layout rationally significantly shortens complete machine length.
Above-described embodiment is preferred version of the present utility model, and the utility model also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and the modification that these are equal to or replace is all included in the scope that the application's claim sets.
