Abstract
The utility model relates to a plastic film tensioning device which comprises a bracket, wherein the bracket is provided with transmission rollers for conveying plastic films; a tension rod is arranged below the bracket and is provided with two tensioning wheels; the plastic films bypass the tensioning wheel at the bottom of the tension rod in S shape from the tail end of the bracket, then turn back around the transmission roller on the bracket, then bypass the second tensioning wheel on the tension rod, and then are conveyed by the transmission rollers. The tension rod is movably chained on the bracket by a pin shaft, and at least three transmission rollers are provided. Compared with the prior art, the plastic film tensioning device has the advantages that the structure is simple, the tensile force of the plastic films can be regulated automatically, breaking or blocking of the plastic films is avoided, and the product quality and production efficiency are ensured.
Description
Technical field
The utility model relates to a kind of printing device, especially relates to a kind of plastic film printing device.
Background technology
Plastic film generally all the situation that degree of tightness differs can occur in transmission course, be easy to make plastic film to draw bad or fold like this, has a strong impact on the quality of plastic film.In order to address this is that, some technical personnels can install and fix bar and draw back plastic film on machine, prevent that plastic film from crossing pine or tension, and still, this fixed link can't be movable, therefore cause plastic film card film phenomenon to occur sometimes, cause the damage of plastic film.
Summary of the invention
The utility model technical matters to be solved provides a kind of plastic film tightening device that can automatic guidance plastic film degree of tension.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme.
This plastic film tightening device comprises support, and support is provided with the live roll that is used for the plastic film transmission; The below is provided with tension rail, and said tension rail is provided with two tension wheels, and plastic film is downward from the terminal live roll of support; The S-shaped tension wheel of walking around the tension rail bottommost; Unrolled then live roll on the support is then walked around second tension wheel on the tension rail, more then through the live roll transmission.
For degree of tension that can the automatic guidance plastic film, further, said tension rail through the bearing pin active link on support.
In order to guarantee that plastic film transmits continuously, more further, said live roll has three at least.
Compared with prior art, the usefulness of the utility model is: this plastic film tensioning device structure is simple, and tension force size that can the automatically regulating plastic film prevents that disconnected film or card film phenomenon from appearring in plastic film, guarantees product design and production efficiency.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model plastic film tensioning device structure scheme drawing.
Among the figure: 1, support; 2, live roll; 3, bearing pin; 4, tension rail; 5, tension wheel;
6, plastic film.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
A kind of plastic film tightening device shown in Figure 1 comprises support 1, and support 1 is provided with the live roll 2 that is used for plastic film 6 transmission, and said live roll 2 has three at least, can guarantee that plastic film 6 transmits continuously; Said support 1 below is provided with tension rail 4; Said tension rail 4 is provided with two tension wheels 5; Plastic film 6 is downward from the live roll 2 of support 1 end, the S-shaped tension wheel 5 of walking around tension rail 4 bottommosts, the live roll 2 on the support 1 that unrolled then; Then walk around second tension wheel 5 on the tension rail 4 again, then through live roll 2 transmission.
For degree of tension that can automatic guidance plastic film 6, said tension rail 4 through bearing pin 3 active links on support 1.
This plastic film tensioning device structure is simple, and tension force size that can automatically regulating plastic film 6 prevents that disconnected film or card film phenomenon from appearring in plastic film 6, guarantees product design and production efficiency
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
