Detailed implementation manners
[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0029] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0030] As Figures 1-4 shown, the present utility model provides a blown film machine for producing release films, including a base 1, a blown film machine 2 fixedly connected to the upper surface of the base 1, a bracket 3 fixedly connected to the upper surface of the base 1, an adjusting roller 4 rotatably connected to the surface of the bracket 3, a cooling structure 5 provided on the surface of the bracket 3, and a limiting structure 6 provided on the surface of the arc plate 506.
[0031] The following specifically describes the specific settings and functions of its cooling structure 5 and limiting structure 6.
[0032] As Figure 2 and Figure 3As shown in the figure, the cooling structure 5 includes two fixing plates 501. The fixing plates 501 are fixedly connected to the bracket 3. A sliding tube 502 is slidably connected to the surface of the bracket 3. A spray tube 503 is fixedly connected to the surface of the sliding tube 502. An air pump 504 is fixedly connected to the surface of the bracket 3. The exhaust end of the air pump 504 is fixedly connected and communicated with a telescopic tube 505. One end of the telescopic tube 505 is fixedly connected and communicated with the spray tube 503. An arc-shaped plate 506 is fixedly connected to the surface of the fixing plate 501. A plurality of card slots 507 are formed on the surface of the fixing plate 501. A card plate 508 penetrates through the sliding tube 502. The size of the card plate 508 is adapted to the size of the card slot 507. A slope is formed on the surface of the card plate 508. When the card plate 508 is inserted into the card slot 507, the card slot 507 functions to limit the position of the card plate 508, thereby limiting the position of the spray tube 503. A magnetic ring 509 is fixedly connected to the surface of the card plate 508. The sliding tube 502 is an iron tube. After the magnetic ring 509 is on the surface of the sliding tube 502, the magnetic ring 509 functions to prevent the card plate 508 from detaching from the card slot 507. A traction rope 510 is fixedly connected to the surface of the card plate 508. One end of the traction rope 510 is fixedly connected to the sliding tube 502. The traction rope 510 functions to prevent the card plate 508 from being lost.
[0033] As Figure 4 shown in the figure, the limiting structure 6 includes two limiting plates 61. The limiting plates 61 are slidably connected to the arc-shaped plate 506. A square plate 62 is fixedly connected to the surface of the limiting plate 61. A screw rod 63 is threadedly connected to the square plate 62. One end of the screw rod 63 close to the arc-shaped plate 506 is rotatably connected to a rough plate 64. After the rough plate 64 abuts against the surface of the arc-shaped plate 506, the rough plate 64 functions to increase the friction between the screw rod 63 and the arc-shaped plate 506. A cross plate 65 is snap-connected to the end of the screw rod 63 far from the arc-shaped plate 506. After the cross plate 65 is removed, it can avoid the situation that the limiting plate 61 becomes loose due to the cross plate 65 being accidentally touched.
[0034] The overall working principle is as follows. When the release film needs to be processed, the melted raw material is conveyed into the film blowing machine 2. After the film blowing machine 2 performs film blowing processing, the release film passes through between the arc plate 506 and the nozzle 503, and then is conveyed by adjusting the conveying direction with the adjusting roller 4. During this process, the air pump 504 is turned on. The air pump 504 will convey high-speed flowing air into the telescopic pipe 505, and then the air will be discharged by the nozzle 503 and blown on the surface of the release film, accelerating the cooling speed of the release film, thereby improving the strength of the release film and preventing the release film from being damaged during the conveying process. At this time, the release film will contact the arc plate 506. When it is necessary to adjust the distance between the nozzle 503 and the release film, the clamping plate 508 is pulled out of the sliding pipe 502, and the clamping plate 508 will be disengaged from the clamping groove 507. At this time, the traction rope 510 serves to prevent the clamping plate 508 from being lost. Then the nozzle 503 is moved. The movement of the nozzle 503 will drive the sliding pipe 502 to slide along the surface of the fixing plate 501. After the adjustment is completed, the clamping plate 508 is inserted back into the clamping groove 507. The clamping groove 507 serves to limit the position of the clamping plate 508, thereby limiting the position of the nozzle 503. At this time, the magnetic ring 509 will be attracted to the surface of the sliding pipe 502. The magnetic ring 509 serves to prevent the clamping plate 508 from being disengaged from the clamping groove 507. By adjusting the distance between the nozzle 503 and the arc plate 506, after the release film is blown on the surface of the arc plate 506, the friction force between the release film and the arc plate 506 can be adjusted to ensure that the release film can be conveyed normally.
[0035] During the process of the release film sliding along the surface of the arc plate 506, the two limiting plates 61 cooperate to limit the sliding path of the release film, facilitating the subsequent conveying of the release film. When it is necessary to limit release films of different sizes, the limiting plates 61 are slid along the surface of the arc plate 506. By adjusting the distance between the two limiting plates 61, release films of different sizes can be limited. After the adjustment is completed, the cross plate 65 is rotated. The screw 63 will rotate with the cross plate 65 and drive the rough plate 64 to move by means of the thread. When the rough plate 64 abuts against the surface of the arc plate 506, the rough plate 64 serves to increase the friction force between the screw 63 and the arc plate 506. The screw 63 serves to limit the position of the square plate 62, thereby limiting the position of the limiting plate 61. Then the cross plate 65 is removed to avoid the situation where the limiting plate 61 becomes loose due to the cross plate 65 being accidentally touched.
