Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1The utility model provides an embodiment: a polymer geomembrane unwinding device, including a table board 1, the four corners of the bottom end of the table board 1 are fixedly connected to table legs, the top of the table board 1 is fixedly connected to a plurality of support blocks 2, the table board 1 here provides support for the support blocks 2, the tops of the two left support blocks 2 are provided with film rolls 3, the front end of the left front support block 2 is fixedly connected to a bottom block 4, the support blocks 2 here provide stable support for the film roll 3, so that it is stable when unwinding.

[0025] Reference Figure 1-Figure 2 The top right side of the bottom block 4 is fixedly connected with a telescopic column 5, and the top of the telescopic column 5 is rotatably connected with a long shaft 6. The telescopic column 5 here will drive the long shaft 6 to move up and down when telescoping, and the bottom end of the long shaft 6 is fixedly connected with a short rod, and a spring 7 is sleeved on the outside of the short rod, so that the bottom end of the short rod is fixedly connected with a pressing block 8. The spring 7 here squeezes the pressing block 8 and the film roll 3 more tightly, which is not easy to cause false alarm, and the inner wall of the bottom end of the pressing block 8 is in contact with the outside of the film roll 3.

[0026] Reference Figure 1-Figure 2 One end of a spring 7 is fixedly connected to the bottom end of a long axis 6, and the other end of a spring 7 is fixedly connected to the top of a pressing block 8. The long axis 6 and the pressing block 8 here provide stable support for the spring 7, so that it operates smoothly. The top of the telescopic column 5 is rotatably connected to a short axis 9, and the left front end of the long axis 6 is fixedly connected to the right side of the short axis 9. The left bottom end of the short axis 9 is fixedly connected to a long rod 10, and the short axis 9 here provides a stable supporting force for the long rod 10.

[0027] Reference Figure 1-Figure 2 The bottom end of the long rod 10 contacts the top end of the alarm 11, and the alarm 11 is fixedly connected to the top left side of the bottom block 4. When the film roll 3 is about to be unwound, the long rod 10 contacts the alarm 11, thereby providing the staff with an opportunity to replace it. The top end of the table board 1 is fixedly connected to a roll control assembly, which includes a support frame 12. The bottom end of the support frame 12 is fixedly connected to the top end of the table board 1. The roll control assembly here is used to control the stretching of the film roll 3. Turntables 13 are fixedly connected to the front and rear ends of the inner wall of the support frame 12.

[0028] Reference Figure 1 and Figure 3 A roller 14 is rotatably connected to the adjacent side of the two turntables 13, and a stretching rod 15 is arranged at the top of the two right support blocks 2. The roller 14 and the stretching rod 15 here are used to stretch the geomembrane to prevent wrinkles. A pressing component is fixedly connected to the right side of the top of the table top 1, and the pressing component includes a bottom box 16. The pressing component here is used to further press the unrolled geomembrane to prevent it from wrinkling due to factors such as friction. Two grooves 17 are provided inside the bottom box 16, and a plurality of springs 18 are arranged inside the grooves 17.

[0029] Reference Figure 3 The multiple springs 18 here make the extrusion tighter and further enhance the stretching and pressing effect on the geomembrane. The inner wall of the groove 17 is slidably connected with a splint 19. One end of the spring 18 is fixedly connected to one side of the inner wall of the groove 17, and the other end of the spring 18 is fixedly connected to one side of the splint 19. The groove 17 and the splint 19 here provide a stable operating space for the spring 18, so that it can be smoothly extended and retracted. The outside of the splint 19 is fixedly connected to a limiting block 20.

[0030] Reference Figure 3 The outer part of the limit block 20 is slidably connected to the inner wall of the groove 17, and the adjacent sides of the two clamping plates 19 are fixedly connected with rubber pads 21. The rubber pads 21 here are used to directly contact the geomembrane. At the same time, due to the special nature of its material, the damage of the geomembrane caused by excessive extrusion is avoided. The adjacent sides of the two rubber pads 21 are in contact.

[0031] Working principle: When using this device, the staff can first place the film roll 3 on the top of the two support blocks 2 on the left side of the table 1, and then pull out one end of the film roll 3, pass it through the top of the roller 14 between the two turntables 13, and the support frame 12 here plays a supporting role, and then pass it through the bottom end of the stretching rod 15, and finally pass it through the middle of the bottom box 16. At this time, start the device to start unwinding the geomembrane. During unwinding, as the film roll 3 gradually decreases, its thickness also decreases.

[0032] At this time, the telescopic column 5 on the bottom block 4 will drop, and at the same time, the long rod 10 under the long axis 6 and the short axis 9 will also drop. The spring 7 here is to make the pressing block 8 fit more closely with the membrane roll 3, with higher accuracy and less prone to false alarms. When the geomembrane on the membrane roll 3 is about to be unwound, the long rod 10 drops to the bottom and touches the alarm 11. At this time, the alarm 11 will sound an alarm to remind the staff that it needs to be replaced in time.

[0033] When the geomembrane on the membrane roll 3 passes through the bottom box 16, the spring 2 18 will cause the rubber pad 21 to press the geomembrane under the action of the clamping plate 19 and the groove 17 to prevent it from wrinkling. At the same time, the limit block 20 here also limits the range of the clamping plate 19.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
