Description

Technical Field

[0001] The utility model relates to the technical field of nylon film production, in particular to a deviation rectifying device for nylon film production. Background Technique

[0002] Nylon film is an organic synthetic material. Through an organic chemical synthesis method, polyamide compounds are transformed into film materials with specific properties. It has good transparency, good gloss, high tensile strength, and high elongation strength, etc.

[0003] When producing nylon film, the nylon film will deflect during the winding process, resulting in the position of the nylon film on the winding roller deviating from the winding position, affecting the production quality of the nylon film. Therefore, a deviation rectifying device is needed to rectify the nylon film. However, in the existing deviation rectifying devices, the two sides of the nylon film are mostly squeezed by movable positioning blocks, and then the nylon film is forced to reset. However, since the nylon film is a flexible material, squeezing the nylon film by the positioning blocks will cause the nylon film at the squeezing position of the positioning blocks to overlap, and the deviation rectifying effect is not ideal. Content of the Utility Model

[0004] The purpose of the utility model is to provide a deviation rectifying device for nylon film production to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A deviation rectifying device for nylon film production, including a fixed frame, the fixed frame is fixedly installed at the end of the conveying frame and the front end of the winding device. The two sides of the fixed frame are symmetrically and fixedly installed with first electric push rods. The moving ends of the first electric push rods pass through the fixed frame and are fixedly installed with mounting plates. One side of the mounting plate is fixedly installed with a mounting frame. The end of the mounting frame is fixedly installed with a second electric push rod. The moving end of the second electric push rod passes through the mounting frame and is fixedly installed with a mounting block. The middle of the mounting block is symmetrically and rotatably installed with connecting rods through pin shafts. One end of the connecting rod away from the mounting block is rotatably installed with a lifting block through a pin shaft. The lifting block is arranged vertically. A pressing wheel for pressing the nylon film is installed on one side of each of the two lifting blocks close to each other. The rotation direction of the pressing wheel is the same as the feeding direction of the nylon film. A photoelectric sensor for monitoring the deflection of the nylon film is fixedly installed in the middle of the fixed frame.

[0006] As a further preferred of this technical solution, rounded corner positioning blocks are symmetrically and fixedly installed on both sides of the lifting block. Positioning frames are symmetrically and fixedly installed on both sides of the mounting frame. Positioning grooves are opened at the ends of the positioning frames corresponding to the positions of the rounded corner positioning blocks. The positioning grooves are slidably connected with the rounded corner positioning blocks.

[0007] As a further optimization of this technical solution, symmetric sliding holes are provided in the middle of the lifting block. A sliding rod is slidably installed inside the sliding hole. A fixing block is fixedly installed between the bottoms of the two sliding rods. The pressing wheel is rotatably installed in the middle of the fixing block. A spring is sleeved on the outer side of the end of the sliding rod away from the fixing block. One end of the spring is fixedly connected to the end of the sliding rod away from the fixing block, and the other end of the spring is fixedly connected to the lifting block.

[0008] As a further optimization of this technical solution, guiding rollers are symmetrically and rotatably installed at both ends of the fixing frame. The nylon film is installed between the two guiding rollers at the same end.

[0011] The utility model provides a deviation rectifying device for nylon film production, which has the following beneficial effects:

[0012] (1) The utility model monitors the deflection of the nylon film in real time through a photoelectric sensor, and then controls the operation of the first electric push rod on the other side where the nylon film deflects through a controller, which will drive the pressing wheel to approach the nylon film. By pulling the mounting block through the second electric push rod, the two pressing wheels will approach each other. The two pressing wheels will squeeze the nylon film, and then drive the mounting plate to move through the first electric push rod. The squeezing of the two pressing wheels on the nylon film will pull the nylon film, which is used to control the deflection position of the nylon film, straighten the middle position of the nylon film, and perform deviation rectifying operation on the nylon film as it is wound up.

[0021] As Figures 1 to 4 shown, rounded corner positioning blocks 11 are symmetrically and fixedly installed on both sides of the lifting block 8, positioning frames 12 are symmetrically and fixedly installed on both sides of the mounting frame 4, positioning grooves 13 are opened at the ends of the positioning frames 12 corresponding to the positions of the rounded corner positioning blocks 11, and the positioning grooves 13 are slidably connected with the rounded corner positioning blocks 11.

[0022] By pulling the mounting block 6 through the second electric push rod 5, the lifting block 8 will be pulled through the connection of the connecting rod 7, the rounded corner positioning blocks 11 on the lifting block 8 will slide inside the positioning grooves 13, and the lifting block 8 will always be kept vertical, the two extrusion wheels 9 will approach each other, and the two extrusion wheels 9 will extrude the nylon film.

[0023] As Figures 1 to 4As shown, symmetrically arranged sliding holes 14 are formed in the middle of the lifting block 8. A sliding rod 15 is slidably installed inside the sliding hole 14. A fixing block 16 is fixedly installed between the bottoms of the two sliding rods 15. The pressing wheel 9 is rotatably installed in the middle of the fixing block 16. A spring 17 is sleeved on the outer side of the end of the sliding rod 15 away from the fixing block 16. One end of the spring 17 is fixedly connected to the end of the sliding rod 15 away from the fixing block 16, and the other end of the spring 17 is fixedly connected to the lifting block 8.

[0024] When the two pressing wheels 9 press the nylon film, the two pressing wheels 9 will approach each other and press against each other. At this time, the sliding rod 15 will slide inside the sliding hole 14 to prevent the nylon film from being damaged due to excessive pressing by the pressing wheel 9.

[0025] As Figures 1 to 4 shown, guide rollers 18 are symmetrically and rotatably installed at both ends of the fixing frame 1. The nylon film is installed between the two guide rollers 18 at the same end.

The second electric push rod 5 pulls the mounting block 6, and through the connection of the connecting rod 7, the lifting block 8 is pulled. The rounded corner positioning block 11 on the lifting block 8 will slide inside the positioning groove 13 and keep the lifting block 8 always vertical. The two pressing wheels 9 will move closer to each other and press the nylon film. At this time, the pressing of the two pressing wheels 9 on the nylon film will not hinder the winding of the nylon film. Then, the first electric push rod 2 drives the mounting plate 3 to move, and the pressing of the two pressing wheels 9 on the nylon film will pull the nylon film to control the deflection position of the nylon film and straighten the middle position of the nylon film. As the nylon film is wound, the deviation rectification operation of the nylon film will be carried out;

[0033] When the two pressing wheels 9 press the nylon film, the two pressing wheels 9 move closer to each other and press against each other. At this time, the sliding rod 15 will slide inside the sliding hole 14 to prevent the nylon film from being damaged due to excessive pressing of the pressing wheel 9 on the nylon film.
