[0030] like Figure 1-Figure 8 As shown, a film aging treatment device comprises a treatment box 1, a driving mechanism 4 is provided at the rear side of the treatment box 1, and a conveying mechanism 2 for aging treatment of polypropylene film;
[0031] In this embodiment: the conveying mechanism 2 includes a plurality of conveying rollers 21 arranged transversely, and the plurality of conveying rollers 21 are rotatably connected inside the processing box 1, and the conveying rollers 21 are of a hollow structure. The plurality of conveying rollers 21 are interconnected through a guide tube 22, and a rotating seat 23 is installed at the connection position between the guide tube 22 and the conveying rollers 21. The conveying belt 24 is sleeved on the outside of the plurality of conveying rollers 21, and a temperature control mechanism 3 for adjusting the temperature of the conveying belt 24 is fixed on both the upper and lower sides. The rear end of the conveying roller 21 on one side of the processing box 1 is the delivery end of the coolant, and the front end of the conveying roller 21 on the other side of the processing box 1 is the delivery end of the coolant. The outside of the conveying belt 24 is made of Teflon high-temperature cloth, and a ring-shaped heat-conducting metal mesh is nested in the middle position. The conveying roller 21, the guide tube 22 and the rotating seat 23 are used to deliver cooling water from the cooling end of the polypropylene film to the heating end, and then the polypropylene film falling on the conveying belt 24 is gradually cooled down, thereby avoiding the cooling speed being too fast to affect the quality.
[0032] In this embodiment: a slope with a certain inclination is provided on one side of the top of the processing box 1, a film inlet is provided at the lower end of the slope of the processing box 1, and a film outlet is provided on the other side of the processing box 1, the temperature control mechanism 3 includes a heating grid 32, the heating grid 32 is installed on one side of the compression assembly 33, and the cooling grid 31 is installed on the other side of the compression assembly 33, two front-to-back symmetrical supply fans 34 are fixed on the slope of the top of the processing box 1, and a heating grid 35 is fixed at the supply fan 34 position inside the processing box 1, and the compression assembly 33 is used to pressurize the refrigerant flowing from the cooling grid 31 to the heating grid 32, and then heat is generated at the heating grid 32 and blown to the position of one end of the conveyor belt 24, and the coolant flowing from the heating grid 32 to the cooling grid 31 expands and absorbs heat, and then cools the other end of the conveyor belt 24, thereby preventing the temperature in the entire area from rising continuously during use.
[0033] In this embodiment: the driving mechanism 4 includes a driving motor 41, which is fixed at the rear end of the film outlet of the processing box 1. The driving motor 41 extends into the rotating part of the processing box 1 and is fixed with a driving gear 42. The upper side of the driving gear 42 is meshed with a driven gear 43 that drives the conveying roller 21 to rotate. The two adjacent conveying rollers 21 are driven by a belt transmission. The driving motor 41 drives the driving gear 42 to rotate, and the rotation of the driving gear 42 drives the driven gear 43 to rotate synchronously. The conveying roller 21 is driven to rotate by the driven gear 43. At this time, the belt between the two adjacent conveying rollers 21 is used to drive multiple conveying rollers 21 to rotate synchronously.
[0034] Working principle: When in use, firstly, the driving motor 41 is used to drive the driving gear 42 to rotate, and the rotation of the driving gear 42 drives the driven gear 43 and the conveying roller 21 to rotate synchronously. At this time, the belt between two adjacent conveying rollers 21 is used to drive multiple conveying rollers 21 to rotate synchronously. At this time, the rotation of multiple conveying rollers 21 is used to drive the conveyor belt 24 to convey. In addition, when the conveyor belt 24 rotates, the compression component 33 starts to press the refrigerant in the cooling grid 31 into the heating grid 32, and then the refrigerant entering the heating grid 32 begins to release heat, and then the temperature of this area is quickly increased. At the same time, the coolant flowing from the heating grid 32 to the cooling grid 31 expands and absorbs heat to make the cooling grid 31 relatively A relatively cold state is then ensured to ensure that the polypropylene film being sent out is in a cooling state. In addition, the heating grid 35 is used for heating and the blower fan 34 blows hot air to the conveyor belt 24 to prevent the temperature of the polypropylene film from dropping too fast during the aging treatment and affecting the quality. At the same time, cooling water is sent into the conveyor roller 21 at the tail of the treatment box 1. At this time, the cooling water passes through the conveyor roller 21, the guide pipe 22 and the rotating seat 23 to gradually flow to one side of the treatment box 1, and then the cooling water temperature will gradually increase. The temperature of the cooling water is gradually transferred to the conveyor belt 24 through the conveyor roller 21, and the uniform cooling effect is achieved through the heat-conducting metal mesh in the middle of the conveyor belt 24. Then, the surface temperature of the conveyor belt 24 is gradually reduced, thereby shortening the aging time of the entire polypropylene film.
[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
