Description

A kind of geomembrane wrap-up

The utility model relates to the wrap-up of a kind of geomembrane (thick plastic film).

Different with the wrap-up of in the past plastic sheeting is, geomembrane is because the thickness of film big (between 0.1 to 2mm), and therefore, the weight per unit area that exists film is big, and the stiffening rolling power of film requires big, and film is not easy to roll up folded defective in the wrapup procedure.

The geomembrane wrap-up that provides a kind of rolling power suitable is provided first purpose of the present utility model.

Second purpose of the present utility model provides geomembrane in wrapup procedure, before and after the motion of film keeps in the rolling overall process synchronously, with the geomembrane wrap-up of speed operation.

First purpose of the present utility model is achieved in that a kind of geomembrane wrap-up, it comprises that transfer member (1) is connected with crosscut parts (3) through paper web dispensing parts (2), center winding device (6), it is characterized in that: roller (4), (5) horizontal parallel setting, coiler (6) places the top between roller (4), (5); Coiler (6) is connected through attaching parts with oil cylinder (8), and the platen bracket gripping member (9) of coiler (6) is arranged in the central authorities of the film volume (7) of rolling.The height ascending velocity of the holder (9) that the elevated height speed of platen bracket gripping member (9) designs oil cylinder (8) in advance according to specified film travel line speed oil-feed speed decision is caused through attaching parts jacking effect.

The utility model can be perfect like this: any one is power operated active rolling part in the platen bracket gripping member (9) of roller (4), (5) and center winding device (6).

In the transfer member (1), be that some registration rollers (10a) of connecting band are staggered with dancer roll (10b) with the geomembrane.

Between transfer member (1) and coiler (6), establish the synchronous tension pick-up spare (12) of band film motion rate sensor, between device (12) and coiler (6), establish the geomembrane operation drive roller sets (13) of carrying out geomembrane kinematic velocity synchro control.

Device (12) is the synchronous tension pick-up of lever, establishes to make the one-way movement control piece (21) that geomembrane can not inverse motion between transfer member (1) and device (12).

The exit of the storage paper web tube groove (22) of parts (2) be provided with band antiparallel motion simultaneously radius arm (14), (15) go out paper web function unit (16).

The staplers (17) with geomembrane and paper web stitching is established in coiler (6) outside.

Behind coiler (6), establish and be installed in can roll up the supporting (20) of (7) and swing a control shelves arm (23) by parallel mobile geomembrane on the pedestal (18).

Establish and can roll up (7) setting parts (24) by upper and lower mobile film in the top of film volume (7), its setting arm can vertical pressing film volume (7) downwards.

According to the needs of different purposes, the thickness requirement of geomembrane is inequality, and the paper web in roller (4), (5) and the center winding device (6) drives holder (9) can be designed to active or passive respectively; When film is thin, roller (4) or (5) can be designed to actv. and holder (9) is separated with paper web, be as the criterion can successfully drive the operation of film volume; When geomembrane is thicker, roller (4) and (5) can be designed to simultaneously actv. or the platen bracket gripping member (9) of parts (6) is designed to actv., to increase operation propulsive effort to film.The needs that increase as the thickness of film also can be designed to the platen bracket gripping member (9) of roller (4), (5) and center winding device (6) active drive simultaneously, to increase rolling power, avoid simultaneously making propulsive effort inhomogeneous, cause the geomembrane distortion owing to single roller drives; Can be in actual design with roller (4), (5) and the platen bracket gripping member (9) of center winding (6) both be designed to simultaneously can active drive, also can be converted to passive type in case of necessity, when roller (4), (5) and center winding (6) be the active drive formula the time, roller (4), (5) drive membrane is with the command speed rolling, make holder (9) simultaneously also drive membrane with identical linear velocity rolling, then the linear velocity control structure must be set, for example: the DC machine that the drive motor of center winding pipe (6) is changed into belt tension control, when film volume (7) diameter increases, if its cireular frequency that is driven in rotation is constant, then the linear velocity of film rolling must increase, the propulsive effort that causes thus spurring film increases, the load of the DC machine of belt tension control increases, thereby make the tension control mechanism control rev down of this motor, make the spin velocity of film volume (7) drop to its film rolling linear velocity and roller (4), (5) the essentially identical state of surperficial rotational line speed, so just energy self-equalizing roller (4), (5) and holder (9) three to the driven in synchronism of film volume (7).(this principle is equally applicable to have only holder, and (9) are the structure of actuator.) roller (4), (5) and center winding (6) are all or part of in case of necessity also can break away from power driven and change passive state into; Registration roller (10a) is for being fixedly mounted on the frame, and dancer roll (10b) is movable lifting (with geomembrane for hanging film); Staggered effect is that when the cutting knife of infeed set-up (3) switched the film volume (7) that has been rolled up, when having one section of short duration time rolling parts to suspend rolling, dancer roll (10b) descended simultaneously, stores the film body that continuous constant speed is sent here between them.Tension pick-up spare (12) detects through its film running velocity with when the preceding film running velocity of transfer member (1) is inequality synchronously, center processor through synchronous controller (13) is handled, two rollers of geomembrane operation roller group (13) are adjusted the running velocity that passes through the film between them on one's own initiative, make it identical with the running velocity of film on the transfer member (1).Device (12) is in suspension status, when film operation appearance is unusual, the gravity that occurs roller (10b) is easily carried on film is unusual with device (12) and is produced the fault of wrong control signal, control piece (21) is owing to (for example: reverse stop barb) be equipped with reverse chocking construction on its roller, so can effectively prevent the film inverse motion, thereby overcome above-mentioned defective.When carrying on the radius arm (14), discharge paper web and place the reservation position of film rolling by getting the core arm, meanwhile arm (15) descending block after paper web make it not be released simultaneously.Radius arm (14) on the function unit (16), (15) are when resetting simultaneously, and arm (14) blocks a back paper web that puts down by moving on the arm (15), the dispensing operation of going round and beginning again and finishing paper web.Because geotechnological thickness, as utilize holder (9) (entering its urgent clamping) to rotate when cooperating rolling from the two ends of paper web, " skidding " phenomenon appears between geomembrane and the paper web easily, can hammer into clip nail with staplers (17) in the outside of geomembrane is one with film and paper web stitching, overcomes " skidding " phenomenon.Regaining holder (9) after film volume (7) is rolled up makes it outwards slip into supporting (20), under the swing guiding of swing arm (23), steadily place the recess of accepting of supporting (20), at this moment accepting (20) and arm (23) along pedestal (18) guide rail moves backward, break away from crosscut parts (3) position, cutting knife on the crosscut parts (3) starts, and will cut off at the film on the volume of the film on the supporting (20).In the process of film volume (7) volume film, the setting arm of parts (24) rides on the film volume (7) with specified pressure, and corresponding the moving up along with the increase of film coil diameter rolled up (7) owing to rolling pulling force greatly be out of shape to the rated pressure of film volume (7) to avoid film but remain.

The utility model, is realized both suitably having increased the rolling propulsive effort according to the characteristics of geotechnological thickness owing to adopted special rolling parts effectively, makes the rolling propulsive effort even again; Cooperate storage film roller group (11) structure, realized uninterruptedly carrying out continuously of wrapup procedure; Cooperate the structure of the geomembrane operation drive roller sets (13) of sensing part (12) and synchro control to realize that the running velocity of complete machine film is synchronous; Cooperate other structure perfect to the automatic winding function of this special thick film of geomembrane.
