[0028] First, see Figure 1 、 Figure 2 and Figure 3 , the specific structure of the flat splint 2 is as follows:

[0029] The flat splint 2 includes a sliding hole 201, an upper splint 202, a lower splint 203, an adjusting bolt 204, a nut 205, a slide 206 and an extrusion spring 207. The two sets of sliding holes 201 are respectively opened at the front and rear ends of the top of the support frame 1. The upper splint 202 is slidably connected to the inner side of the sliding hole 201, and the lower splint 203 is slidably connected to the inner side of the sliding hole 201 and is located below the upper splint 202. The two sets of sliding holes 201 are used to facilitate the upper splint 202 to move upward. And the sliding of the lower splint 203, two sets of adjusting bolts 204 are fixedly connected to the front and rear ends of the top of the upper splint 202, the nut 205 is threadedly connected to the top of the adjusting bolt 204, and two sets of slides 206 are respectively fixedly connected to the front and rear ends of the bottom of the lower splint 203, the extrusion spring 207 is sleeved on the inner side of the slide 206, and a slide groove 7 is opened at the top of the support frame 1 and at the position of the slide 206, and the slide 206 is slidably connected to the inner side of the slide groove 7.

[0030] During use of the present invention, the nut 205 is first rotated to adjust the upper splint 202 upwards by adjusting the bolt 204, so that the distance between the upper splint 202 and the lower splint 203 is increased, and the plastic tarpaulin is then passed between the upper splint 202 and the lower splint 203, and the nut 205 is then rotated to move the upper splint 202 downwards, so that the upper splint 202 and the lower splint 203 press the plastic tarpaulin, so that the surface of the plastic tarpaulin remains flat when it is rolled up. When the winding drum 305 rolls up the plastic tarpaulin, the two groups of slides 206 support the lower splint 203, and the two groups of slides 206 can slide on the inner side of the slide groove 7, and under the action of the extrusion spring 207, the lower splint 203 maintains elasticity, so that the plastic tarpaulin is pressurized and stabilized and remains smooth when it is rolled up.

[0031] Also, see Figure 1 、 Figure 2 and Figure 4 The specific structure of the winding component 3 is as follows:

[0032] The winding assembly 3 includes a fixed foot 301, a circular groove 302, a rotating head 303, a clamping joint 304 and a winding drum 305. The two groups of fixed feet 301 are fixedly connected to the front and rear ends of the top of the support frame 1 respectively. The circular groove 302 is opened at the top of the fixed foot 301, and the rotating head 303 is rotatably connected to the inside of the circular groove 302. The fixed foot 301 can support the rotating head 303, and the central axis of the rotating head 303 passes through the fixed foot 301 and is rotatably connected to the support frame 1. The clamping joint 304 is clamped to the end of the rotating head 303 away from the support frame 1. The top of the fixed foot 301 is rotatably connected with a top cover to ensure the stability of the connection between the clamping joint 304 and the rotating head 303. The rotating head 303 is used to drive the clamping joint 304 to rotate. The winding drum 305 is clamped between the two groups of clamping joints 304, and the two groups of clamping joints 304 are used to drive the winding drum 305 to rotate.

[0033] Among them, see Figure 2 and Figure 4 A card slot 8 is provided on the surface of the rotating head 303, and a card block 9 is fixedly connected to the back of the card joint 304. The card block 9 is adapted for use with the card slot 8. The card block 9 is engaged with the card slot 8 to ensure that the rotating head 303 can smoothly drive the card joint 304 to rotate. A number of anti-slip teeth 10 are evenly distributed on the outside of the card joint 304. The anti-slip teeth 10 are adapted for use with the winding drum 305. The anti-slip teeth 10 are sleeved on the inner side of the winding drum 305, so that the winding drum 305 is firmly connected to the card joint 304, and can rotate smoothly when the plastic tarpaulin is rolled up.

[0034] For further information, see Figure 1 and Figure 2 The bottom of the support frame 1 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to a pulley group 12. The top of the pulley group 12 is fixedly connected to the rotating head 303. The motor 11 can drive the pulley group 12 to operate. When the pulley group 12 operates, it drives the rotating head 303 to rotate. When the rotating head 303 rotates, it drives the card joint 304 to rotate. The rotation of the card joint 304 drives the winding drum 305 to reel in the plastic tarpaulin.

[0035] For further information, see Figure 1 、 Figure 2 and Figure 5The baffle 5 is a U-shaped plate. The left end of the baffle 5 is slidably connected to the support frame 1 through the first slide rod 13, and the right end of the baffle 5 is slidably connected to the support frame 1 through the second slide rod 14. The left end of the baffle 5 is higher than the gap between the upper splint 202 and the lower splint 203, and the right end of the baffle 5 is higher than the fixed foot 301, ensuring that the plastic tarpaulin is always located between the two sets of baffles 5 when rolling up, preventing the plastic tarpaulin from deflecting when rolling up.

[0036] The working process of this utility model:

[0037] When the utility model is in use, first clamp the two sets of clamping joints 304 to the front and rear ends of the winding drum 305, then clamp the clamping block 9 on the back of the clamping joint 304 to the clamping groove 8 on the surface of the rotating head 303, close the top cover of the fixed foot 301, rotate the nut 205 to adjust the upper clamping plate 202 upwards through the adjusting bolt 204, so that the distance between the upper clamping plate 202 and the lower clamping plate 203 is increased, and then the plastic tarpaulin is passed through between the upper clamping plate 202 and the lower clamping plate 203, and then the hand crank 6 is rotated. The hand crank 6 drives the bidirectional screw rod 4 to rotate, thereby driving the two sets of baffles 5 to slide towards each other, so that the baffles 5 can guard the two sides of plastic tarpaulins of different widths and can always keep the plastic tarpaulin in the middle position of the winding drum 305 to prevent the plastic tarpaulin from deflecting. The upper and lower clamping plates 202 and 203 are fixed to the outside of the winding drum 305, and the nut 205 is rotated to move the upper clamping plate 202 downward, so that the upper and lower clamping plates 202 and 203 press the plastic tarpaulin, so that the surface of the plastic tarpaulin is kept flat when winding. The motor 11 is started again, and the motor 11 drives the pulley group 12 to run. When the pulley group 12 runs, it drives the rotating head 303 to rotate. When the rotating head 303 rotates, it drives the card joint 304 to rotate. The card joint 304 rotates, thereby driving the winding drum 305 to wind the plastic tarpaulin. When the winding drum 305 winds the plastic tarpaulin, the two sets of slides 206 can slide on the inner side of the slide groove 7, and under the action of the extrusion spring 207, the lower clamping plate 203 maintains elasticity, so that the plastic tarpaulin is under pressure and stable, and wrinkles will not be generated during winding and the winding can be kept smooth.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
