Detailed Description
The invention will be further described in detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the invention and the specific objects and functions achieved.
Referring to fig. 1 and 7: a CPP protective film production device with tensile strength adjustment comprises a bracket 1 and a processing device 2; the processing device 2 comprises a heating device 22, a stretching device 21 and a monitoring device 24 which are sequentially arranged from top to bottom along the vertical direction; the stretching device 21 is arranged on the bracket 1, the protective film body 3 passes through the stretching device 21, and the stretching device 21 stretches the protective film body 3; a step in which a heating device 22 is provided at the front end of the stretching device 21, and the heating device 22 heats and softens the protective film body 3 which is about to enter the stretching device 21; the monitoring device 24 is arranged at the rear end of the stretching device 21, and the monitoring device 24 monitors the stretched width of the protective film body 3; further comprising clamping means 23 for providing a clamping force to the stretching means 21; the device further comprises an adjusting device 25, the width preset value of the protective film body 3 is preset in the device, and when the width value of the protective film body 3 measured by the monitoring device 24 is larger than the width preset value, the adjusting device 25 stretches the protective film body 3 secondarily.
The heating device 22 is composed of two heating plates 221, the protective film body 3 passes through the space between the two heating plates 221, and because the heating device 22, the stretching device 21 and the monitoring device 24 are arranged from top to bottom along the vertical direction, when the heating device 22 heats the protective film body 3, the protective film body 3 is softened, if the protective film body 3 is transported by adopting a transverse transportation mode, the heated and softened protective film body 3 is gradually deformed, and the deformation rate is uncontrollable, namely, the excessive heating and softening easily leads the protective film body 3 to stretch and break before entering the stretching device 21, because when the heated protective film body 3 is transported by adopting the transverse transportation mode, the protective film body 3 is heated and then bends under the action of gravity, the bending trend of the protective film body 3 is unpredictable, so that the heated protective film body 3 has uneven thickness when transported to the stretching device 21, the subsequent uniform stretching of the protective film body 3 is not facilitated, the protective film body 3 is always in a vertical state when heated and stretched by adopting a vertical arrangement mode, namely, the protective film body 3 is in a vertical state after being heated, and stably deforms under the action of gravity because the protective film body 3 is not bent but slightly stretched along the vertical direction, the protection film body 3 is prevented from breaking before being transported to the stretching device 21, the whole working principle is as follows, the heating device 22 heats the protection film body 3, the protection film body 3 is softened and enters the stretching device 21 for stretching, the clamping device 23 provides clamping force for the stretching device 21, the clamping device 23 ensures that the stretching device 21 cannot slip when stretching the protection device, further the uniformity of the protection film body 3 after being stretched is ensured, if the slipping phenomenon occurs, the stretching device 21 can suddenly apply larger pulling force to the protection film body 3 when slipping occurs, the surface of the protection film is damaged or the situation of being stretched overlength occurs, the length of the protective film body 3 is lengthened and the thickness is thinned by stretching the stretching device 21, the stretched protective film body 3 is wound on the monitoring device 24, the monitoring device 24 detects the width of the stretched protective film body 3, the wider the width of the protective film body 3 is, the thicker the thickness of the protective film body 3 is, the narrower the width of the protective film body 3 is, the thinner the thickness of the protective film body 3 is, thus the thickness of the protective film can be determined uniformly by detecting the width of the protective film body 3, the thickness of the stretched protective film body 3 can be controlled by controlling the stretched width of the protective film body 3, and then avoided protection film body 3 to lead to the cracked condition in the width too narrow when tensile, if through monitoring devices 24's detection, when finding that the width of protection film body 3 is greater than the width default, then adjusting device 25 starts, adjusting device 25 carries out the secondary to protection film body 3 and stretches for the width default accords with the width default, if the width of protection film body 3 is less than the width default, then indicate that stretching device 21's tensile strength is too big, need reduce stretching device 21's tensile strength this moment, make equipment can last stable output steady quality's protection film.

Since the plush is uniformly arranged on the peripheral wall of the first rotating wheel 242, after the stretched film body 3 is stretched by the stretching device 21, the plush needs to be wound on the first rotating wheel 242, so that the plush on the first rotating wheel 242 can be pressed by the film body 3 to generate an indentation, the camera end of the camera 241 points to the first rotating wheel 242, the equipment is provided with a preset width value of the film body 3 after the film body 3 is stretched to be qualified, the camera 241 detects the indentation formed by the film body 3 on the first rotating wheel 242, the stretched film body 3 meets the requirement when the stretched film body 3 width reaches the preset width value, if the stretched film body 3 width does not reach the preset width value, the stretching device 21 needs to be timely adjusted, namely, the detected film body 3 width is too wide, the stretching strength of the stretching device 21 needs to be continuously increased, otherwise, the detected film body 3 width is too narrow, the stretching strength of the stretching device 21 needs to be excessively large, and the stretching strength of the stretching device 21 needs to be reduced.
