DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0020] The following describes some embodiments of the present utility model with reference to the accompanying drawings.

[0021] Embodiment 1:

[0022] Combined with Figures 1-4As shown in the figure, this embodiment provides an anti-wrinkle winding mechanism for an optical film material, including: a main body mechanism 100.

[0023] Among them, the main body mechanism 100 includes a heat preservation box body 110, a sealing door 120 hinged on both sides of the heat preservation box body 110, a winding roller 130 rotatably installed in the inner cavity of the heat preservation box body 110, guide pipes symmetrically installed in the inner cavity of the heat preservation box body 110, electric telescopic rods 150 symmetrically fixed at the top of the heat preservation box body 110 and extending into the heat preservation box body 110, a detection piece 160 fixed at the bottom end of the electric telescopic rod 150, a U-shaped frame 170 hung on the detection piece 160, and a tension roller 180 rotatably installed on the U-shaped frame 170.

[0024] The heat preservation box body 110 is made of heat preservation materials and is used to install other components. The sealing door 120 is hinged on the heat preservation box body 110, and together with the heat preservation box body 110, it forms a closed environment, isolating it from the external environment, which can avoid the situation that the optical film material expands and contracts due to the temperature change of the external environment during winding and generates wrinkles.

[0025] The winding roller 130 is used to collect the optical film material, and two guide rollers 140 are provided for guiding the optical film material.

[0026] The electric telescopic rod 150 is used to install the detection piece 160 and drive the detection piece 160 to move up and down. The detection piece 160 includes a support rod 161 fixed at the end of the electric telescopic rod 150, T-shaped hanging plates 162 symmetrically fixed at both ends of the support rod 161 and passing through the U-shaped frame 170, and a pressure sensor 163 installed on the T-shaped hanging plate 162. The support rod 161 is used to install the T-shaped hanging plate 162, and the T-shaped hanging plate 162 is used to hang the U-shaped frame 170 to ensure the stability of the U-shaped frame 170. The bottom end of the pressure sensor 163 is fixed on the T-shaped hanging plate 162, and the top end is in close contact with the inner side of the U-shaped frame 170. Through the above settings, the electric telescopic rod 150 drives the support rod 161 to move, the support rod 161 drives the T-shaped hanging plate 162 to move, and the T-shaped hanging plate 162 drives the U-shaped frame 170 to move, that is, drives the tension roller 180 to move to adjust the winding tension of the optical film material.

[0027] In addition, when the detection piece 160 drives the U-shaped frame 170 to move up, the greater the tension of the optical film material, and at this time, the greater the pressure value detected by the pressure sensor 163. On the contrary, when the detection piece 160 drives the U-shaped frame 170 to move down, the smaller the tension of the optical film material, and at this time, the smaller the pressure value detected by the pressure sensor 163.

[0028] Round rods 1611 are symmetrically fixed at the top end of the support rod 161, and the round rods 1611 movably pass through the heat preservation box body 110 and extend out, which are used to limit the movement of the support rod 161 and ensure the stability of the support rod 161 during movement.

[0029] Working principle and usage process of the present utility model: During use, the optical film material is wound around the guiding tube on one side, then around the tension roller 180, and then around the guiding tube on the other side and wound on the winding roller 130. At this time, the winding roller 130 rotates to wind the optical film material. The tension during the winding of the optical film material drives the tension roller 180 to move downward. The downward movement of the tension roller 180 drives the U-shaped frame 170 to move downward. The pressure sensor 163 monitors the downward pressure of the U-shaped frame 170 in real time. When the monitored value is different from the set value, the electric telescopic rod 150 is started. The start of the electric telescopic rod 150 drives the support rod 161 to move. The movement of the support rod 161 drives the U-shaped frame 170 to move through the T-shaped hanging plate 162. The movement of the U-shaped frame 170 drives the tension roller 180 to move, adjusting the winding tension of the optical film material. In addition, the setting of the heat preservation box body 110 and the sealing door 120 can isolate the environment inside the heat preservation box body 110 from the outside world, avoiding the optical film material from wrinkling due to the thermal expansion and contraction caused by the change of the outside environmental temperature and optical friction.

[0030] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
