Description

PTFE film wrap-up

Technical field

The utility model relates to PTFE film production equipment technologies, more particularly to a kind of PTFE film wrap-up.

Background technique

The fabric substrate of PTFE film material be glass fibre, it be as tetrafluoroethene it is aggregated made of macromolecule chemical combination Object has excellent chemical stability, corrosion resistance, sealing property, high lubrication, non-stickiness, electrical insulation and good anti-aging resistance to Power is used as engineering plastics, can be made into pipe, stick, band, plate, film etc., be generally used for the higher corrosion resistant pipe of performance requirement Road, container, pump, valve and radar processed, high frequency communications equipment, radio component parts etc., it is in the actual production process, existing to use PTFE membrane wrap-up cannot achieve the automatic winding of PTFE film material, can not flexibly be adjusted according to the size of PTFE film material Section can not adjust drawing volume Tensity size.

Utility model content

The technical problem to be solved by the utility model is in order to overcome the shortcomings in the prior art, the utility model mentions For a kind of PTFE film wrap-up.

The utility model solves its technical problem technical solution to be taken: a kind of PTFE film wrap-up, including Rack, winding component and adjusting component, the winding component includes bracket, wind-up roll and driven roller, and the wind-up roll both ends are equal Equipped with the bracket, the wind-up roll is connect with the holder pivots, and the driven roller is supported to be set on the wind-up roll side wall and be used In driving the wind-up roll to rotate along axis, the adjusting component includes elastic-friction plate and elastic element, the elastic-friction Plate is set to below the wind-up roll, and the elastic element is set between the bracket and rack for driving the wind-up roll separate The elastic-friction plate.

Rack is used to support winding component and adjusts component, and bracket is used to support wind-up roll and driven roller, and wind-up roll can be with Bearing is arranged by both ends to connect with holder pivots for winding PTFE film, driven roller, which is supported, to be set on wind-up roll side wall for passing through Frictional force drives wind-up roll to rotate along axis, and driven roller revolving speed is constant, and elastic element is used to support the wind-up roll on bracket, When the PTFE film wound on wind-up roll gradually becomes more, elastic element is gradually compressed, and wind-up roll moves closer to be set to below Elastic-friction plate, elastic-friction plate for contact with wind-up roll side wall to wind-up roll apply resistance, prevention wind-up roll along axis It rotates, the PTFE film weight wound on wind-up roll is bigger, and compressing elastic-friction plate benging amplitude is bigger, elastic-friction plate and winding The area of roller contact is more, and the resistance applied to wind-up roll is bigger, then wind-up roll velocity of rotation is slower, to control winding Roller winds the tension of PTFE film, to guarantee PTFE film volume, winding is uniform from inside to outside.

Further, the first friction portion cooperated with the driven roller, the wind-up roll right side are equipped on the left of the wind-up roll Equipped with the second friction portion cooperated with the elastic-friction plate.First friction portion be used for driven roller cooperate, when wind-up roll obtain Rotary force winds PTFE film, and the second friction portion is used to cooperate with elastic-friction plate, is wound according to PTFE film on wind-up roll How much control wind-up roll revolving speeds, thus control wind-up roll winding PTFE film tension, guarantee PTFE film volume winds from inside to outside Uniformly.

Further, motor is sequentially connected in the driven roller, the motor is set on the bracket.

The beneficial effects of the utility model are: a kind of PTFE film wrap-up provided by the utility model, using wind-up roll The size of frictional force between elastic-friction plate adjusts wind-up roll winding tension, guarantees that PTFE film is wound uniformly from inside to outside.

Specific embodiment

The utility model is described in detail presently in connection with attached drawing.This figure is simplified schematic diagram, only in a schematic way Illustrate the basic structure of the utility model, therefore it only shows composition related with the utility model.

In the present embodiment, elastic element 5 selects spring, and elastic-friction plate 6 selects rubber slab, as shown in Figure 1-3, this is practical A kind of novel PTFE film wrap-up, including rack 1, winding component and adjust component, the winding component include bracket 2, Wind-up roll 3 and driven roller 4,3 both ends of wind-up roll are equipped with the bracket 2, and the wind-up roll 3 passes through axis with the bracket 2 8 rotation connections are held, the driven roller 4, which is supported, to be set to for driving the wind-up roll 3 to rotate along axis on 3 side wall of wind-up roll, The adjusting component includes rubber slab and spring, and the rubber slab is set to 3 lower section of wind-up roll, and rubber board ends are using support Bar 9 is supported in rack 1, and the spring is set between the bracket 2 and rack 1 for driving the wind-up roll 3 far from described Elastic-friction plate 6, the spring one end and bracket 2 are welded to connect, and the spring other end and rack 1 are welded to connect.

It is equipped with the first friction portion cooperated with the driven roller 4 on the left of the wind-up roll 3, is equipped on the right side of the wind-up roll 3 With the second friction portion of rubber slab cooperation.

Motor 7 is sequentially connected in the driven roller 4, the motor 7 is set on the bracket 2.

Working principle:

Motor 7 starts, and 7 revolving speed of motor is constant, and motor 7 drives driven roller 4 to rotate, and driven roller 4, which is supported, is set to 3 side of wind-up roll On wall by frictional force drive wind-up roll 3 along axis rotate, start wind PTFE film, when the PTFE film wound on wind-up roll 3 by When gradual change is more, weight increases, and spring is gradually compressed, and wind-up roll 3 moves closer to rubber slab, when wind-up roll 3 sticks rubber slab, Rubber slab applies resistance to wind-up roll 3, slows down 3 rolling speed of wind-up roll, and the PTFE film weight wound on wind-up roll 3 is bigger, Oppress rubber slab bending amplitude it is bigger, the area that rubber slab is contacted with wind-up roll 3 is more, to wind-up roll 3 application resistance just Bigger, then 3 velocity of rotation of wind-up roll is slower, thus control wind-up roll 3 wind PTFE film tension, thus guarantee PTFE film volume by It is interior and wind outside uniformly.

It is enlightenment, through the above description, relevant work with the above-mentioned desirable embodiment according to the utility model Personnel can carry out various changes and amendments in without departing from the scope of the utility model completely.This item utility model Technical scope is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
