For a long time, this type of land has been difficult to effectively utilize and develop. The use of salt-alkali-resistant membrane materials can significantly improve the saline-alkali land environment, increasing soil temperature, maintaining optimal moisture conditions, and improving soil fertility.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0030] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0032] See also Figure 2 、 Figure 5 As shown, the utility model is a tensioning adjustment part and a tensioning adjustment device for preparing and winding salt-alkali resistant film, comprising a winding table 1, a winding device 2 is provided on the top of the winding table 1, and a guide mechanism 3 is provided on the inner wall of the winding device 2. An adjustment groove 4 is opened on the top of the winding table 1, and a driving device 5 is provided on the top of the winding table 1. The inner wall of the adjusting groove 4 is slidably connected with a displacement component 6, and the output end of the driving device 5 is engaged with the displacement component 6. The inner wall of the displacement component 6 is slidably connected with a tensioning part 7, and a lifting device 8 is provided on the outer surface of the winding table 1. The output end of the lifting device 8 passes through the tensioning part 7 and is threadedly connected to it, and a guide rod 9 is fixedly connected to one side of the tensioning part 7.

[0033] When the salt-alkali resistant film needs to be wound up, the winding device 2 is set up on the top of the winding platform 1, and the film is pulled so that it extends along the bottom of the guide rod 9, passes the top surface of the tensioning member 7, and then extends to the bottom of the guide mechanism 3 and is wrapped around the outer surface of the winding device 2. Then, the winding device 2 is started to wind up the film. When the film becomes loose during the winding process, the driving device 5 can be started to make the displacement component 6 move along the inside of the adjustment groove 4 away from the winding device 2. At this time, the displacement component 6 drives the tensioning member 7 on the top to move together. At the same time, the lifting device 8 starts to drive the tensioning member 7 to move along the inner side of the displacement component 6, so that it moves upward or downward until the film is supported in a flat state and stops, so that the film is no longer loose and wrinkled and is in a normal winding state.

[0034] The utility model places the tensioning member 7 on the inner side of the displacement assembly 6, and cooperates with the guide rod 9 to provide a certain support height and tension during the film winding and conveying process. During the winding process, the displacement assembly 6 is driven by the driving device 5 to drive the tensioning member 7 to move laterally along the adjustment groove 4, and the lifting device 8 drives the tensioning member 7 to rise and fall. The support height and the lateral support distance of the film during winding can be adjusted simultaneously on one side of the guide mechanism 3, thereby providing an efficient and convenient tension adjustment effect when winding the salt-alkali resistant film, making it less likely to have wrinkles and unevenness during winding that affect the winding process, thereby improving the winding and forming quality of the salt-alkali resistant film.

[0035] In one embodiment, for the above-mentioned winding device 2, the winding device 2 includes a support frame 201, a winding roller 202 is inserted into the inner wall of the support frame 201, and one end of the winding roller 202 is threadedly connected to a reel 203.

[0036] The winding roller 202 is inserted into the inner wall of the support frame 201 and connected to the end of the reel 203. The motor, transmission belt and other components can drive the reel 203 to drive the winding roller 202 to rotate, thereby providing driving force for the winding of the film, so that the film has a self-winding effect.

[0038] By passing the adjustment rod 301 through the support frame 201 and connecting it with the support plate 302, when necessary, the guide roller 303 can be rotated and displaced by rotating the adjustment rod 301 at a position close to the winding roller 202, thereby adjusting its support angle and providing an auxiliary adjustment effect of the support tension at a position close to the winding position to prevent the film from wrinkling at the winding position.

[0039] In one embodiment, the driving device 5 includes a driving motor 501 , an output end of the driving motor 501 is fixedly connected to an output shaft 502 , and an outer surface of the output shaft 502 is fixedly connected to a first gear 503 and a second gear 504 ;

[0040] The displacement assembly 6 includes a displacement tooth plate 601, and a top plate 602 is fixedly installed on the top of the displacement tooth plate 601. There are two sets of displacement tooth plates 601 and top plates 602. The first gear 503 and the second gear 504 are respectively engaged with the two sets of displacement tooth plates 601.

[0041] By starting the driving motor 501, the output shaft 502 drives the first gear 503 and the second gear 504 to rotate synchronously, and at the same time drives the two sets of displacement gear plates 601 to move along the inside of the adjustment slot 4, thereby causing the top plate 602 to drive the tensioning member 7 to move synchronously.

[0042] Through the cooperation of the two sets of displacement tooth plates 601 and the first gear 503 and the second gear 504, a stable displacement driving force can be provided for the top plate 602, so that the top plate 602 can provide a stable displacement support effect for the tensioning member 7 when moving, while changing the support distance and the supporting tensioning force.

[0044] The two groups of sliders 702 are respectively slidably connected to the inner walls of the two groups of top plates 602. When the displacement top plate 602 moves, the tensioning roller 701 is driven to synchronously move laterally. At the same time, after the lifting device 8 is started, the threaded sleeve 703 is driven to move and drive the slider 702 to move along the inner wall of the top plate 602 to adjust the support height of the tensioning roller 701.

[0045] In one embodiment, for the above-mentioned lifting device 8, the lifting device 8 includes a lifting motor 801, and the output end of the lifting motor 801 is fixedly connected to a threaded shaft 802, and the threaded shaft 802 passes through and is threadedly connected to the inside of the threaded sleeve 703.

[0046] When the lifting motor 801 is started, it drives the threaded shaft 802 to rotate and drives the threaded sleeve 703 to move in its vertical direction, thereby driving the slider 702 to slide along the inner wall of the top plate 602, and at the same time changing the height of the tensioning roller 701. When the top plate 602 moves laterally, the height of the tensioning roller 701 can be changed synchronously to achieve the effect of quickly adjusting the tension of the salt-alkali resistant membrane support.

[0047] In one embodiment, for the top plate 602 , the outer surface of the top plate 602 is fixedly connected to the side plate 603 , and the guide rod 9 is fixedly connected to the inner wall of the side plate 603 .

[0048] By supporting the guide rod 9 on the inner wall of the side plate 603, an initial guide function can be provided for the output of the salt-alkali resistant film on one side of the tensioning roller 701, so that the film has a conveying path restriction function when being conveyed and wound.

[0049] In one embodiment, for the winding platform 1 , a closed box 10 is fixedly installed on the top of the winding platform 1 , and the closed box 10 is located outside the output shaft 502 .

[0050] The sealing box 10 is located outside the output shaft 502 to form an enclosed sealing effect, thereby reducing the noise transmission effect when the output shaft 502, the first gear 503 and the second gear 504 are in operation.

[0051] Through the above technical solution, 1. By placing the tensioning member 7 on the inner side of the displacement assembly 6, and cooperating with the guide rod 9 to provide a certain support height and tension during the film winding and conveying process, during the winding process, the displacement assembly 6 is driven by the driving device 5 to drive the tensioning member 7 to move laterally along the adjustment groove 4, and the lifting device 8 is cooperated to drive the tensioning member 7 to move up and down, the support height and the lateral support distance of the film during winding can be adjusted simultaneously on one side of the guide mechanism 3, thereby providing an efficient and convenient tension adjustment effect for the salt-alkali resistant film during winding, making it less likely to have wrinkles and unevenness during winding that affect the winding process, thereby improving the winding and forming quality of the salt-alkali resistant film; 2. By using two sets of displacement tooth plates 60 1, in cooperation with the first gear 503 and the second gear 504, a stable displacement driving force can be provided for the top plate 602, so that the top plate 602 can provide a stable displacement support effect for the tensioning member 7 when moving, and at the same time, the support distance is changed, and the support tensioning force changes synchronously; when the lifting motor 801 is started, the threaded shaft 802 is driven to rotate and drive the threaded sleeve 703 to move along its vertical direction, thereby driving the slider 702 to slide along the inner wall of the top plate 602, and at the same time, the height of the tensioning roller 701 is changed, so that the height of the tensioning roller 701 can be changed synchronously when the top plate 602 is displaced horizontally, so as to achieve the effect of quickly adjusting the support tension of the salt-alkali resistant membrane.
