It is listed between two stands, limits the mobile restriction plate of elastic volume, be hinged between the adjacent two stands and be pressed on elastic volume
On pressing plate, the regulating mechanism for adjusting platen pressure is provided on the pressing plate.But this elastic is put on assembly line
Contact of the winding apparatus due to elastic with let off roll be actually can not tension adjusting, that is to say that the pulling force of back segment has much,
Elastic just has much with the direct contact force of let off roll, and the fatigue strength of two such roller can be constant always, service life also base
Originally it maintains within the scope of one.But by the research of the applicant, the contact force of two rollers and elastic, energy are suitably converted
The enough service life for improving roller to a certain extent, thereby produces this patent.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of structures simply, can be improved the elastic of service life
Unreel guiding device.Which solve the shorter technical problems of existing elastic unwinding device service life.
To achieve the above object, the utility model uses following technical scheme: a kind of elastic unreels guiding device, including
Rack, interval are set to three or more guide rods in rack, are rotatably arranged in the mounting base at rack both ends, in the mounting base
It rotationally sets side by side there are two rotating roller, two rotating rollers are respectively arranged on the two sides of guide rod, are located at mounting base in the rack
The both ends of lower section are threaded with puller bolt respectively, and against the lower end of mounting base, the other end is stretched for one end of the puller bolt
Out outside rack, one end that the puller bolt stretches out outside rack is equipped with swing handle.
Further, each guide rod is U-shaped, and the both ends of each guide rod are inserted in rack.
Further, two free ends of each guide rod are equipped with thread segment, and each guide rod is perforated through rack, each guide rod
Thread segment on be located at rack upper and lower ends be respectively equipped with locking nut.
Further, the rotating roller includes the mandrel being rotatably arranged in rack, the sleeve being sheathed on outside mandrel, sets
In the self-lubricating engineering plastics ring for being used to support sleeve on mandrel.
Further, the graduated scale for being equipped with below mounting base and being used to indicate mounting base rotational angle is located in the rack.
By using preceding solution, the beneficial effects of the utility model are: this elastic, which unreels guiding device, passes through peace
Dress seat is rotatably arranged in rack, and the both ends in the rack below mounting base are threaded with hold out against spiral shell respectively
Bolt, one end of the puller bolt is against the lower end of mounting base, and the other end stretches out outside rack, and the puller bolt stretches out outside rack
One end be equipped with swing handle, may be implemented in this way mounting base rotation adjustment, thus to adjust the stress shape of two rotating rollers
Condition, such compartment is time-interleaved, and two rotating rollers can be made to obtain tired buffering, so that two rotating rollers of raising use the longevity
Life；Further, each guide rod is U-shaped, and the both ends of each guide rod are inserted in rack, and the strong of guide rod can be improved in this way
Degree, greatly improves its stability, decreases shake；Further, two free ends of each guide rod are equipped with screw thread
Section, each guide rod are perforated through rack, and the upper and lower ends that rack is located on the thread segment of each guide rod are respectively equipped with locking nut, this
Sample can make the stable connection of guide rod and rack greatly improve；Further, setting by self-lubricating engineering plastics ring
It sets, rotating effect can be improved, reducing dust impurity bring influences；It further, can be accurate by the setting of graduated scale
Rotational angle.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the right view of Fig. 1.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
With reference to Fig. 1, Fig. 2, the present embodiment provides a kind of elastics to unreel guiding device, including rack 1, interval are set to rack 1
On five guide rods 2, be rotatably arranged in the mounting base 3 at 1 both ends of rack, be rotationally equipped with side by side in the mounting base 3
Two rotating rollers 4, two rotating rollers 4 are respectively arranged on the two sides of guide rod 2, the both ends point of 3 lower section of mounting base are located in the rack 1
It is not threaded with puller bolt 5, against the lower end of mounting base 3, the other end stretches out outside rack 1 for one end of the puller bolt 5,
One end that the puller bolt 5 stretches out outside rack 1 is equipped with swing handle 51.Each guide rod 2 is U-shaped, and the both ends of each guide rod 2 are equal
It is inserted in rack 1.Two free ends of each guide rod 2 are equipped with thread segment 21, and each guide rod 2 is perforated through rack 1, each to be oriented to
