Description
Technical field
The utility model relates to printing and bag making manufacturing machine fields, more particularly, to a kind of idler roller hold-down devices.
Background technique
Traditional idler roller hold-down devices are when encountering power failure or the emergency cases such as production line breaks down, due to a lack of electric power
It supports, so that cylinder loses gas to make idler roller cause the production product on idler roller to be subjected to displacement due to sinking from recurrence,
Therefore it will increase unnecessary workload.
Utility model content
The utility model is to solve the problems, such as that idler roller from recurrence because sinking under the emergency case set forth above arrived, thus
A kind of idler roller hold-down devices, including device noumenon are provided, described device ontology includes idler roller one, idler roller two and support
Frame, the idler roller one are mutually fixed by shaft with support frame, and the idler roller two is connected by connecting bracket with idler roller one
It connects, cylinder is provided on support frame as described above, the lower end of the cylinder is provided with pneumatic jack, one end phase of the pneumatic jack and idler roller two
Connection, one end of the idler roller one is provided with pull rod, tension spring, the other end of the tension spring and support is fixed on the pull rod
Frame is connected.
The beneficial effects of the utility model are: the structure design of the utility model is reasonable, can occur in power failure or production line
It effectively prevents idler roller from sinking because of self weight when failure, is subjected to displacement the production product on idler roller.
Detailed description of the invention
The utility model will illustrate by example and with reference to the appended drawing, in which:
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the side structure schematic view of the utility model；
In figure: 1, device noumenon；2, tension spring；3, idler roller one；4, idler roller two；5, connecting bracket；6, cylinder；7, it draws
Bar；8, pneumatic jack；9, support frame；10, shaft.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
Any feature of this specification, unless specifically stated, can be equivalent by other or substitution with similar purpose it is special
Sign is replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics.
A kind of idler roller hold-down devices as shown in Figure 1, including device noumenon 1, described device ontology 1 include idler roller one
3, idler roller 24 and support frame 9, the idler roller 1 are fixed by shaft 10 and 9 phase of support frame, and the idler roller 24 passes through
Connecting bracket 5 is connected with idler roller 1, and cylinder 6 is provided on support frame as described above 9, and the lower end of the cylinder 6 is provided with pneumatic jack
8, the pneumatic jack 8 is connected with one end of idler roller 24, and one end of the idler roller 1 is provided with pull rod 7, on the pull rod 7
It is fixed with tension spring 2, the other end of the tension spring 2 is connected with support frame 9.
In use, the setting of connecting bracket 5 can make idler roller 1 and idler roller 24 synchronizes running, described
The setting of cylinder 6, which can control pneumatic jack 8, makes idler roller carry out lift or pushing according to demand, and the setting of the tension spring 2 can be drawn
Firmly there is a phenomenon where sink for idler roller under emergency cases to prevent from having a power failure etc. for idler roller 1.
The beneficial effects of the utility model are: the structure design of the utility model is reasonable, can occur in power failure or production line
It effectively prevents idler roller from sinking because of self weight when failure, is subjected to displacement the production product on idler roller.
The utility model is not limited to specific embodiment above-mentioned.The utility model expands to any in this specification
The new feature of middle disclosure or any new combination, and disclose any new method or process the step of or any new group
It closes.
