[0039] Refer to Figure 1 , 2The elastic mechanism 3 comprises a semicircular column 301 fixedly connected to the surface of the fixed plate 208, a semicircular block 302 arranged in an annular array on one side surface of the semicircular column 301, an annular block 303 with one side inner wall abutting against the other side surface of the semicircular column 301, a movable cavity 304 arranged in the interior of the other side of the annular block 303, a pushing block 305 with two ends movably penetrating through the outer wall of one side of the annular block 303 and sliding in the interior of the movable cavity 304, a spring 306 with two ends fixedly connected to one side of the pushing block 305 and one side of the inner wall of the movable cavity 304, an auxiliary groove 307 symmetrically arranged in the two ends of one side of the pushing block 305, a fixed column 308 with two ends fixedly connected to the upper and lower surfaces of the movable cavity 304, a rotating block 309 with the middle part rotatably connected to the exterior of the fixed column 308, one end of the rotating block 309 clamped in the interior of the auxiliary groove 307, the other end of the rotating block 309 clamped in the interior of an auxiliary groove 312, a sliding column 310 with the outer wall movably penetrating through one side of the inner wall of one side of the annular block 303, a spring 311 with two ends fixedly connected to the middle part of the interior of the pushing block 305 and one end of the sliding column 310, and the auxiliary groove 312 symmetrically arranged on the two sides of the sliding column 310.

[0040] One end of a fixed column 313 is fixedly connected to the exterior of one side of the auxiliary groove 307 of the pushing block 305, the other side of the fixed column 313 is slidingly connected to the interior of a circular hole 314, the circular hole 314 is arranged in the inner wall of the annular block 303 and the movable cavity 304, one side of the middle part of an arc-shaped block 315 is fixedly connected to the other end of the sliding column 310, the other side of the arc-shaped block 315 abuts against one side surface of the semicircular column 301, a semicircular groove 316 is arranged on the other side of the arc-shaped block 315, the semicircular groove 316 is sleeved on the exterior of the semicircular block 302, one end of an abutting column 317 is fixedly connected to one side of the outer wall of the annular block 303, the other end of the abutting column 317 is slidingly connected and clamped in the interior of a sliding rail block 318, and the bottom of the sliding rail block 318 is fixedly connected to the upper surface of the workbench 1 and corresponds to the abutting column 317.

[0041] As the fixed plate 208 slides, the abutment 317 gradually moves towards the slide rail block 318 and inserts into the slide rail block 318. After the sliding block 202 is fixed by the pin, the semi-cylinder 301 is fixed by the connection between the fixed plate 208 and the sliding block 202. At this time, the operator squeezes one side of the annular block 303 and one side of the pushing block 305. Through the operator's squeeze, the spring 306 begins to contract simultaneously. One end of the rotating block 309 is restricted to rotate outside the fixed column 308 by the auxiliary groove 307. The other end of the rotating block 309 pushes the sliding column 310 towards the pushing block 305 through the auxiliary groove 312. At this time, the spring 311 begins to contract, and one side of the arc block 315 gradually stops abutting the semi-cylinder 301. When the semi-circular block 302 is no longer stuck inside the semi-circular groove 316, the height of the abutment 317 can be adjusted. By adjusting the height of the abutment 317, the tightness of the plastic film can be adjusted.

[0042] After the plastic film is adjusted, the operator manually releases the squeezed annular block 303 and push block 305. At this time, spring 1 306 and spring 2 311 reset the push block 305 through their own elasticity. With the reset of the arc block 315, the rotating block 309 begins to rotate outside the fixed column 1 308, resetting the sliding column 1 310. With the reset of the sliding column 1 310, the arc block 315 abuts against the surface of the semi-cylinder 301 again. The semi-circular groove 316 is fitted onto the outside of the semi-circular block 302, thus fixing the adjusted tension abutment 317.

[0043] Reference Figure 1 , 3 The guiding and flattening mechanism 4 includes L-shaped blocks 401 fixedly connected to both sides of the middle portion of the surface of the fixed plate 208; the upper end of the first fixed block 402 is symmetrically fixedly connected to the lower end of one side of the L-shaped block 401; the outer wall of the first fixed block 402 slides inside the upper end of the second fixed block 403; the bottom of the second fixed block 403 is symmetrically fixedly connected to both sides of the upper surface of the workbench 1; the upper end of the hollow block 404 is fixedly connected to the lower surface of the middle portion of the L-shaped block 401; and the upper end of the fixing frame 407 is symmetrically fixedly connected to one side of the upper portion of the workbench 1. Connected to both sides of the hollow block 404, the lower ends of the two fixing brackets 407 are respectively locked at one end of the first rotating column 408 and one end of the second rotating column 409. The other side of the first rotating column 408 is rotatably connected and locked inside the L-shaped block 401, and the other side of the second rotating column 409 is rotatably connected and slides inside the second fixing block 403. One end of the second sliding column 410 is locked inside the L-shaped block 401, and the other end of the second sliding column 410 is slidably connected inside the second fixing block 403.

[0044] When the fixed plate 208 is sliding, the fixed block one 402 starts to slide on the top of the fixed block two 403, and the rotating column two 409 and the sliding column two 410 start to slide in the middle of the fixed block two 403. The center of the rotating column one 408 and the rotating column two 409 is in the same horizontal line with the center of the sleeve, which prevents the dislocation of the rotating column one 408 and the rotating column two 409.

[0045] When the fixing of the plastic film sleeve and the preliminary setting of the height of the abutting column 317 are completed, the operator manually pulls out one end of the plastic film. First, the plastic film passes from the bottom of the first abutting column 317, through the space between the second sliding column two 410 and the rotating column one 408 and the rotating column two 409, and then passes above the second abutting column 317, through the space between the second sliding column two 410 and the rotating column one 408 and the rotating column two 409, and finally passes below the third abutting column 317 and is fixed to the outer wall of the sleeve on the surface of the winding roller 103, completing the connection of the plastic film.

[0046] Then, the motor one 102 is connected to the power supply through the wire, and the motor one 102 is started through the switch. At this time, the plastic film starts to flatten according to the route, and the outer wall of the abutting column 317 and the outer wall of the sliding column two 410, the rotating column one 408 and the rotating column two 409 start to flatten. The outer wall of the rotating column one 408 and the rotating column two 409 starts to adhere to the two sides of the plastic film and expands to guide the plastic film to completely expand.

[0047] When the plastic film is not tight during the flattening process, the abutting column 317 can be adjusted again according to the tightness required by the plastic film by manually pressing the annular block 303 and the pushing block 305. After the adjustment is completed, the operator can fix it after releasing his hand.

[0048] The implementation principle of the flattening device for the plastic film is as follows: Before the operator needs to flatten the plastic film, the operator manually inserts the sleeve into the outside of the unwinding roller 101 and the winding roller 103. Then, the circular through hole two 207 is in the same axis with the unwinding roller 101 and the winding roller 103 by sliding the square block 206. Then, the unwinding roller 101 and the winding roller 103 are inserted into the inside of the circular through hole two 207 by sliding the sliding block 202. When the sleeve is abutted by the square block 206, the sleeve is fixed by inserting the pin into the circular through hole one 203 and the circular through slot 204.

[0049] When the sliding block 202 slides, the fixed plate 208 with the abutting column 317 is inserted into the inside of the sliding rail block 318, and then the operator extrudes the annular block 303 and the pushing block 305, so that the spring one 306 and the spring two 311 are contracted, the rotating block 309 is rotated, through the rotation of the rotating block 309, the semicircular block 302 is no longer clamped in the inside of the semicircular groove 316, when the semicircular block 302 is no longer clamped in the inside of the semicircular groove 316, the height of the abutting column 317 can be adjusted, the height of the route required for designing the plastic film is run, at the same time, the tightness of the plastic film can be adjusted in time through the operation in the process of flattening the equipment, when the sliding block 202 slides, the rotating column two 409 and the sliding column two 410 start to slide in the middle of the fixed block two 403, through the sliding of the rotating column two 409, the center of the rotating column one 408 and the rotating column two 409 is at the same horizontal line with the center of the sleeve.

[0050] After the adjustment of the abutting column 317 is completed, the operator no longer extrudes the annular block 303 and the pushing block 305, at this time, the spring one 306 and the spring two 311 reset the whole tensioning mechanism 3 through the elasticity of themselves, at this time, the semicircular groove 316 is re-set outside the semicircular block 302, the arc block 315 is abutted on the surface of the semicircular column 301 again, the running route height adjusted is fixed.

[0051] Then the operator manually draws one end of the plastic film out, and the plastic film is drawn according to the running route through the abutting column 317, the rotating column one 408, the rotating column two 409 and the sliding column two 410, and finally fixed on the sleeve outside the winding roller 103, after the operation is completed, the operator starts the motor one 102 through the switch, through the start of the motor one 102, the plastic film starts to flatten, the rotating column one 408 and the rotating column two 409 are transmitted, at this time, the outer wall of the rotating column one 408 and the rotating column two 409 can expand and guide the two sides of the plastic film adhered.

[0052] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: all equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
