Description

Technical Field

[0001] The invention relates to the technical field of rolling equipment, and in particular to a composite geomembrane rolling equipment and a rolling method. Background Art

[0002] The composite geomembrane rolling equipment is a key equipment in the geomembrane production line. It has the characteristics of high automation, compact structure, flexible adjustment, durability and reliability. It can automatically complete the rolling process and ensure that the membrane is flat and firm, which is of great significance to improving production efficiency and product quality.

[0003] The patent with publication number CN217534813U discloses a geomembrane winding device, including a support frame and a driving clamping roller, a pressure roller mechanism and a winding mechanism fixed on the support frame in sequence along the geomembrane winding direction. The winding mechanism can fit the geomembrane and the winding paper roller tightly together, which helps the geomembrane winding work and improves the geomembrane winding efficiency.

[0004] During the winding process, although traditional winding equipment is equipped with a tension roller to adjust the tension, it still has the problem of being unable to automatically adjust the position of the winding roller according to the film thickness in real time. This limitation is particularly obvious after the equipment has been running for a long time, which will lead to a decrease in the tension control accuracy, thereby affecting the flatness of the film surface. In addition, during the roll changing process of existing non-stop winding equipment, it is generally necessary to use external power equipment to adjust the position of the two winding rollers on the disc. This design not only makes the equipment structure cumbersome, but also takes up a large space.

[0024] S1. First, before the winding work starts, the film body is pulled to the outside of the winding roller in the winding device located below, and the winding motor of the winding roller is started to drive it to rotate;

[0025] S2. As the winding roller rotates, the thickness of the film rolled up outside the winding roller gradually increases; the film then presses against the film pressing roller in the shrinking mechanism, and the overall position of the film pressing roller gradually moves downward;

[0026] S3, after the film pressing roller moves downward, the position of the movable bracket starts to move downward, and then the position of the movable tooth plate moves downward, and conflicts with the shaft gear in the transmission mechanism, thereby driving the shaft gear on the upper rotating shaft to rotate;

[0027] S4, after the rotating shaft located at the top rotates, the pulley at its end rotates, and after the power is transmitted through the transmission belt, the rotating shaft located at the bottom is driven to rotate;

[0029] S6, when the movable frame plate at the bottom moves toward the locking device 400 at the bottom, the pressing block contacts with the outrigger rods in one set of the locking devices, thereby driving the movable slider to move, and then driving the locking block to move inside the storage slot through the connecting rope;

[0030] S7, at this time, the locking block is separated from the insert block in the upper winding device, and the upper winding device as a whole is moved away from the upper locking device 400 and moved to the rear end of the fixed frame plate under the elastic force of the first pressure spring in the contraction mechanism;

[0031] S8, as the plug-in block on the outer side wall of the convex box in the winding device at the bottom enters the inside of the insertion hole, it cooperates with the locking block in another set of locking devices to fix the position of the plug-in block, so that the position of the winding device at the bottom remains fixed after the rolled film is taken down;

[0032] S9. Subsequently, the external operator starts the membrane separation device, and the membrane separation device immediately presses the membrane toward the winding roller in the winding device located above;

[0033] S10, then, the film separation device cuts the film with the internal cutting knife, and cooperates with the internal film guide roller to attach the film to the outside of the winding roller in the winding device located above;

[0034] S11, at this time, start the winding motor in the winding device located above, so as to continue the film winding operation and restore the position of the film separation device;

[0035] S12. After that, after the winding roller in the winding device below has finished winding up the cut part of the film, the winding motor is turned off and the film is taken out from the winding roller.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The composite geomembrane winding equipment and winding method, as the thickness of the membrane body on the winding roller in the winding device located below increases, the overall position of the winding device located below can be changed through the cooperation of the contraction mechanism and the transmission mechanism, ensuring that the surface tension of the membrane body is constant during the winding process, and avoiding the surface flatness of the membrane body being affected, thereby ensuring the winding quality.

[0038] 2. The composite geomembrane winding equipment and winding method, when the winding device located at the bottom moves as a whole to the front end inside the fixed frame plate, the pressure block can drive the change of the structure inside one group of locking devices, and the winding device located at the top is automatically moved to the position corresponding to the membrane separation device under the elastic force of the internal first pressure spring. The switching of the winding device and the cutting and connection of the membrane are automatically completed without stopping the machine. The symmetrically arranged winding devices shrink the use space of the traditional non-stop winding devices, save external power equipment, and have a simpler structure.

[0060] Specifically, the longitudinal section of the fixed frame plate 110 is in a U shape, and square slots penetrating up and down are formed in the upper and lower horizontal plates.

When the film separating device 300 works, the cylinder drives the film separating device 300 to move up and down, and the cutting knife cuts the film body 500, and then the film body 500 is guided by the film guide rollers.

[0064] In this embodiment, as Figure 7-10 shown, the winding device 200 includes a moving mechanism 210, a winding motor 220 arranged outside the moving mechanism 210, a winding roller 230 rotating with the rotation of the output shaft of the winding motor 220, a shrinking mechanism 240 arranged below the winding roller 230, and a transmission mechanism 250 arranged below the shrinking mechanism 240;

[0065] Specifically, the moving mechanism 210 includes a moving frame plate 211, an outwardly convex box body 212 arranged on the bottom surface of the moving frame plate 211 with an open bottom, a plurality of insertion blocks 213 arranged on the outer side wall of the outwardly convex box body 212, a pressing block 214 arranged on the outer side wall of the moving frame plate 211, and two placement racks 215 arranged on the top horizontal plate of the moving frame plate 211.

[0066] Furthermore, the longitudinal cross-section of the movable frame plate 211 is L-shaped, a limiting slide groove 2110 is opened at the center position of the top surface of the movable frame plate 211, and plate surface grooves 2111 are opened on the top surface of the movable frame plate 211 on both sides of the limiting slide groove 2110.

[0068] In this embodiment, Figure 7-9 As shown, the contraction mechanism 240 includes a moving bracket 241, a film pressing roller 242 disposed inside the moving bracket 241, a moving tooth plate 243 that moves with the movement of the moving bracket 241, and a first pressure spring 245 disposed on the bottom surfaces of the left and right ends of the moving bracket 241;

[0069] Specifically, the winding motor 220 is fixedly connected to the outer side wall of the movable frame plate 211 by bolts, and the winding roller 230 is coaxially connected to the output shaft of the winding motor 220 .

[0070] Furthermore, the laminating roller 242 is rotatably connected to the inside of the movable bracket 241 , the movable tooth plate 243 is clamped and fixed on the bottom surface of the movable bracket 241 , and the movable tooth plate 243 is slidably connected to the inside of the limiting sliding groove 2110 .

[0071] Furthermore, the upper and lower ends of the first pressure spring 245 are respectively welded and fixed to the bottom surface of the movable bracket 241 and the top surface of the horizontal plate of the movable frame plate 211, and a limiting telescopic rod 244 is provided inside the first pressure spring 245. The upper and lower ends of the limiting telescopic rod 244 are respectively fixedly connected to the bottom surface of the movable bracket 241 and the top surface of the horizontal plate of the movable frame plate 211 by bolts.

[0072] Furthermore, after the winding motor 220 is started, the film body 500 is pulled to the outside of the winding roller 230. As the winding roller 230 rotates, the thickness of the film body 500 wound on the outside of the winding roller 230 gradually increases; the film body 500 then presses against the film pressing roller 242, and the overall position of the film pressing roller 242 begins to gradually move downward, driving the position of the movable bracket 241 to begin to move downward, and then driving the position of the movable tooth plate 243 to move downward.

[0073] In this embodiment, Fig.10As shown, the transmission mechanism 250 includes two upper and lower parallel rotating shafts 251 and a shaft gear 252 that rotates as the rotating shaft 251 rotates;

[0074] Specifically, the rotating shaft 251 located at the top is rotatably connected to the inside of the limiting bracket 150, and the left and right ends of the rotating shaft 251 located at the bottom are respectively rotatably connected to the inner walls of the left and right ends of the convex box body 212, and the shaft gear 252 is fixed to the outer wall of the rotating shaft 251 by a pin, the shaft gear 252 located at the top is meshed with the movable tooth plate 243, and the shaft gear 252 located at the bottom is meshed with the fixed tooth plate 130, and the left and right ends of the upper and lower rotating shafts 251 are fixedly connected with pulleys 253 by pins, the size of the upper pulley 253 is larger than the size of the lower pulley 253, and a transmission belt 254 is sleeved between the upper and lower sets of pulleys 253.

[0075] Furthermore, after the position of the movable tooth plate 243 moves downward, it conflicts with the shaft gear 252 in the transmission mechanism 250, thereby driving the shaft gear 252 on the upper rotating shaft 251 to rotate. After the upper rotating shaft 251 rotates, the pulley 253 at its end rotates, and after the power is transmitted through the transmission belt 254, it drives the rotating shaft 251 located below to rotate. After the shaft gear 252 on the rotating shaft 251 located below rotates, it conflicts with the fixed tooth plate 130, thereby driving the convex box body 212 together with the movable frame plate 211 as a whole to move forward inside the fixed frame plate 110.

[0076] In this embodiment, Fig.11 As shown, the locking device 400 includes a locking block 410, a second pressure spring 420 disposed on the outer side wall of the locking block 410, a moving slider 430 disposed on the outer side of the fixed frame plate 110, and a connecting rope 450 connected between the locking block 410 and the moving slider 430;

[0077] Specifically, the locking block 410 is slidably connected to the inside of the storage groove 112, the left and right ends of the second pressure spring 420 are respectively welded and fixed to the outer wall of the locking block 410 and the inner wall of the storage groove 112, the movable slider 430 is slidably connected to the outer wall of the limiting bracket 150, and an extension rod 440 is integrally formed on the outer wall of the movable slider 430, and the two ends of the connecting rope 450 are respectively adhered to the outer wall of the locking block 410 and the outer wall of the movable slider 430.

[0078] Furthermore, when the movable frame plate 211 moves toward the front end, the pressing block 214 contacts with the extending rod 440 in one group of the locking devices 400, thereby driving the movable slider 430 to move, and then driving the locking block 410 to move inside the storage groove 112 through the connecting rope 450. At this time, the locking block 410 is separated from the insertion block 213 in the winding device 200 located above, and the winding device 200 located above is moved to the rear end of the fixed frame plate 110 as a whole under the elastic force of the first pressure spring 245 in the retraction mechanism 240.

[0081] S2. As the winding roller 230 rotates, the thickness of the film body 500 wound outside the winding roller 230 gradually increases; the film body 500 then presses against the film pressing roller 242 in the shrinking mechanism 240, and the overall position of the film pressing roller 242 gradually moves downward;

[0082] S3, after the film pressing roller 242 moves downward, the position of the movable bracket 241 starts to move downward, and then the position of the movable gear plate 243 moves downward, and contacts with the shaft gear 252 in the transmission mechanism 250, thereby driving the shaft gear 252 on the upper rotating shaft 251 to rotate;

[0083] S4, after the rotating shaft 251 at the top rotates, the pulley 253 at the end thereof rotates, and after the power is transmitted through the transmission belt 254, the rotating shaft 251 at the bottom is driven to rotate;

[0084] S5, the shaft gear 252 on the rotating shaft 251 at the bottom rotates with it and conflicts with the fixed tooth plate 130, thereby driving the convex box body 212 and the movable frame plate 211 to move as a whole inside the fixed frame plate 110 toward the locking device 400 at the bottom;

[0085] S6, when the movable frame plate 211 at the bottom moves toward the locking device 400 at the bottom, the pressing block 214 contacts with the outrigger rod 440 in one set of the locking devices 400, thereby driving the movable slider 430 to move, and then driving the locking block 410 to move inside the receiving groove 112 through the connecting rope 450;

[0086] S7, at this time, the locking block 410 is separated from the insert block 213 in the upper winding device 200, and the upper winding device 200 as a whole is moved away from the upper locking device 400 and moved to the rear end of the fixed frame plate 110 under the elastic force of the first pressure spring 245 in the retracting mechanism 240;

[0087] S8, after the insert block 213 on the outer side wall of the convex box body 212 in the winding device 200 at the bottom enters the interior of the insertion hole 113, the locking block 410 in another set of locking devices 400 is cooperated to fix the position of the insert block 213, so that the position of the winding device 200 at the bottom remains in a fixed state after the rolled film body 500 is taken down;

[0088] S9, then, the external operator starts the membrane separation device 300, and the membrane separation device 300 immediately presses the membrane 500 toward the winding roller 230 in the winding device 200 located above;

[0089] S10, then, the film separation device 300 cuts the film 500 by means of the internal cutting knife, and cooperates with the internal film guide roller to attach the film 500 to the outside of the winding roller 230 in the winding device 200 located above;

[0090] S11, at this time, the winding motor 220 in the winding device 200 located above is started, so as to continue the winding operation of the film 500 and restore the position of the film separation device 300;

[0091] S12 . After that, after the winding roller 230 in the winding device 200 at the bottom has finished winding up the cut part of the film 500 , the winding motor 220 is turned off, and the film 500 is taken out from the winding roller 230 .
