Two groups of support plates 4 are fixedly connected below the transverse plate part of the concave plate 301, and two groups of third rollers 5 are rotatably connected between the two groups of support plates 4.
Specifically, when the PVA film is used, the PVA film passes through the space between the two groups of first rollers 304 and the second rollers 305 and then passes through the space between the two groups of third rollers 5, the two groups of first rollers 304, the two groups of second rollers 305 and the two groups of third rollers 5 are all tightly arranged, when the PVA film needs to be adjusted in tightness degree in a conveying process, the second motor 303 is started to drive the turntable 302 to slowly rotate, so that the two groups of first rollers 304 and the two groups of second rollers 305 are changed in position, the PVA film is twisted in different degrees, and after the needed position is adjusted, the second motor 303 is closed, so that the PVA film is relatively tightened or loosened compared with the previous PVA film.
Further, the final output direction of the polyvinyl alcohol film is kept unchanged by the arrangement of the fixing plate 4 and the third roller 5.
Example 2:
referring to fig. 1, a film winding mechanism 2 is disposed below the seat plate 1, and the film winding mechanism 2 includes a winding post 201, a rotating rod 202, a triangular bracket 203, a first motor 204, a sliding groove 205, a sliding block 206, an annular plate 207, a screw rod 208, a kidney-shaped baffle 209, a rotating handle 210, a threaded hole 211, a rotating shaft 212, and a through hole 213; two groups of triangular supports 203 are fixedly connected below the seat plate 1, a winding column 201 is arranged between the two groups of triangular supports 203, the side walls of two ends of the winding column 201 are fixedly connected with rotating rods 202, and one end of each rotating rod 202 is rotatably connected with the triangular support 203; a first motor 204 is fixedly installed on one side of the left tripod 3, and the motor 204 is fixedly connected with the rotating rod 202. The inner parts of two ends of the winding column 201 are respectively provided with four groups of sliding grooves 205, the sliding grooves 205 are distributed in the winding column 201 in an annular array mode, the inner part of each sliding groove 205 is connected with a sliding block 206 in a sliding mode, the outer wall of one side of each sliding block 206 is fixedly connected with an annular plate 207, and the annular plates 207 are sleeved on the outer wall of the winding column 201; the inside of spout 205 is through setting up bearing fixedly connected with lead screw 208, and the one end threaded connection of lead screw 208 is in the inside of winding post 201, and other end threaded connection has waist shape baffle 209, and waist shape baffle 209 one end is inside through setting up bearing fixedly connected with pivot 212, pivot 212 one end and winding post 201 lateral wall fixed connection. The other end of the screw 208 is provided with a rotating handle 210 inside. A threaded hole 211 is formed in the other end of the waist-shaped baffle 209, and the screw rod 208 is in threaded connection with the threaded hole 211. The through hole 213 is opened in the inside of the slider 206, and the inside of the through hole 213 is fixedly connected with the screw rod 208 by arranging a bearing.
Specifically, when in use, the rotating rod 202 and the roller 201 are driven to rotate by the first motor 204, so that the PVA film is wound. When the annular plate 207 is needed to position the two ends of the PVA film in the film rolling process to prevent deviation, the two ends of the PVA film can be blocked in the film rolling process through the arrangement of the annular plate 207. When the distance between the two sets of annular plates 207 needs to be adjusted and moved, the screw 208 is rotated by rotating the handle 210, one end of the screw 208 moves inside the roller 201, the screw 208 drives the shaped plates 207 to move through the sliding blocks 206, and therefore the distance between the two sets of shaped plates 207 is adjusted to adapt to the winding of PVA films with different widths.
Further, the other end of the screw rod 208 can be connected and supported through the arrangement of the waist-shaped baffle 209, and the stability of the mechanism is improved.

Further, the screw rod 208 is moved towards the inner side by rotating the handle 210, that is, the distance between the two sets of annular plates 207 is reduced, so that the other end of the screw rod 208 is separated from the inside of the kidney-shaped baffle 209, because the rotating shaft 212 is fixedly connected to the inside of one end of the kidney-shaped baffle 209 through the bearing, the other end of the kidney-shaped baffle 209 can be inclined towards one side, the screw rod 208 is rotated to move towards the outer side until one end of the screw rod 208 is completely separated from the inside of the winding column 201, the annular plate 207 can be taken down, the annular plate 207 and the sliding block 2066 can be conveniently mounted and dismounted, and the adjustability of the film winding mechanism 2 is increased.
Furthermore, the maximum diameter of the clamping end of the rotating handle 210 is smaller than or equal to the diameter of the screw rod 208, so that the screw rod 208 is separated from the inside of the kidney-shaped baffle 209 in the rotating process, and the adjustment of the screw rod 208 is facilitated.
The scheme in this embodiment can be selectively combined with the scheme in other embodiments.
