Abstract
The utility model discloses a tensioner, including support (5) of two parallels, being equipped with extend the wheel base (1) and the wheel base (2) that extends down on two spinal branch frame (5) respectively, go up the wheel base (1) that extends and take turns base (2) with extension down and all lean out, just two bases are parallel to each other, the wheel base (2) that extends is down gone up and is installed down the wheel (3) that extends through the axle, and it has T shape upset (4) to go up to link on the wheel base (1) that extends, and install on last extensions wheel base (1) at T shape upset (4 a) both ends on same straight line, and the other end links has balancing weight (6), and the tip of balancing weight (6) is equipped with the extension and takes turns (7), go up the to extend wheel (7) and wheel (3) the parallel that extends down, and go up the wheel (7) that extends and can press after through upset (4) upset on (3) are taken turns in the extension under. The utility model discloses pull forward when tensile at the film, can be need not artifical inspection with the film tensioning automatically, great saving the labour.
Description
Technical field
The utility model relates to a kind of tightening device, is mainly used in film tensioning.
Background technology
Film is in the process of rolling or cutting, need film tensioning, otherwise normal rolling or cutting can be affected, and do not have good method can carry out tensioning to it at present, need to check film at set intervals, then want timely tensioning to even up if find that there is fold, the labour intensity of workman is larger.
Utility model content
The utility model in order to solve current thin film rolling or cutting time easy fold problem, for herein is provided a kind of tightening device, comprise two parallel supports 5, wherein a support 5 is provided with the wheel base 1 that extends, another root support 5 is provided with lower extension wheel base 2, it is all outward-dipping that base 2 is taken turns in described upper extension wheel base 1 and lower extension, and two bases are parallel to each other; Described lower extension wheel base 2 is provided with extension wheel 3 by axle, the described upper wheel base 1 that extends is connected with the flip piece 4 of a T-shaped, described T-shaped flip piece 4 two ends are on the same line arranged on extends on wheel base 1, the end of the other end is connected with clump weight 6, the end of clump weight 6 is provided with extension wheel 7, described upper extension wheel 7 is parallel with lower extension wheel 3, and upper extension wheel 7 can be pressed on lower extension wheel 3 after being overturn by flip piece 4.
The utility model tightening device, described upper extension wheel 7 and lower extension wheel 3 are made by rubber.
The beneficial effects of the utility model are:
The utility model only needs the both sides being arranged on film, by film as on lower extension wheel, again the upset of upper extension wheel is pressed on lower extension wheel, because two wheels that extend are outward-dipping, therefore when film is stretched to front haulage, film can be tensioned automatically, without the need to hand inspection, has saved labour power greatly.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the upper schematic diagram of taking turns when not overturning that extends;
Fig. 2 is that the upper wheel that extends is turned to the lower schematic diagram extended when taking turns upper.
Detailed description of the invention
All features disclosed in this specification sheets, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification sheets, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
Tightening device as depicted in figs. 1 and 2, comprise two parallel supports 5, wherein a support 5 is provided with the wheel base 1 that extends, and another root support 5 is provided with lower extensions and takes turns base 2, it is all outward-dipping that base 2 is taken turns in described upper extension wheel base 1 and lower extension, and two bases are parallel to each other; Described lower extension wheel base 2 is provided with extension wheel 3 by axle, the described upper wheel base 1 that extends is connected with the flip piece 4 of a T-shaped, described T-shaped flip piece 4 two ends are on the same line arranged on extends on wheel base 1, the end of the other end is connected with clump weight 6, the end of clump weight 6 is provided with extension wheel 7, described upper extension wheel 7 is parallel with lower extension wheel 3, and upper extension wheel 7 can be pressed on lower extension wheel 3 after being overturn by flip piece 4, described upper extension wheel 7 and lower extension wheel 3 are made by rubber.
The utility model only needs the both sides being arranged on film, by film as on lower extension wheel, again the upset of upper extension wheel is pressed on lower extension wheel, because two wheels that extend are outward-dipping, therefore when film is stretched to front haulage, film can be tensioned automatically, without the need to hand inspection, has saved labour power greatly.
The utility model is not limited to aforesaid detailed description of the invention.The utility model expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
