Description

Technical Field

[0001] The present invention relates to the technical field related to nylon films, and in particular to a high-toughness, low-hydrophilicity pure nylon film and a manufacturing method thereof. Background Art

[0002] Nylon film is a very tough film with good transparency, good gloss, tensile strength and other excellent qualities. It can be widely used in the market. At present, nylon film is used more and more widely in our production and life, and has been widely used in food, medicine, chemical industry and other fields. Nylon film is usually required to have good toughness, and the reason for the rupture of existing nylon film may be uneven force, which is more likely to break at the edges when pulled. Since nylon film has poor barrier properties to water vapor and has high moisture absorption and moisture permeability, it has certain limitations in application. Therefore, the existing nylon film has the disadvantages of uneven force when pulled, which can easily lead to breakage, and high hydrophilicity.

The shortcomings of this utility model are that the nylon film produced by this device has the disadvantages of uneven force when pulled, which can easily lead to breakage, and high hydrophilicity. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of nylon films in the prior art, such as uneven force when pulled, which can easily lead to breakage, and high hydrophilicity. It provides a high-toughness, low-hydrophilicity pure nylon film and a method for manufacturing the same, which uses a reinforcing layer to improve the toughness of the nylon film and adds hydrophobic material to the adhesive layer to improve the hydrophobicity.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A high-toughness, low-hydrophilicity pure nylon film comprises a reinforcing layer, a film layer and an adhesive layer. The reinforcing layer has a mesh structure, the size of the reinforcing layer corresponds to the size of the film layer, film layers are installed on both sides of the reinforcing layer, and the film layer is connected to the reinforcing layer through an adhesive layer.

[0007] The structure of the reinforcement layer is a mesh structure, and both sides of the reinforcement layer are connected to the film layer with an adhesive layer. When the connected nylon film is pulled or subjected to external force, the reinforcement layer adopts a mesh structure made of elastic material, which has a certain elasticity. The force is dispersed by the internal reinforcement layer, so that the nylon film can withstand greater force to improve the toughness of the nylon film. The film layers on both sides of the reinforcement layer are made of pure nylon film, and hydrophobic material is added to the adhesive layer used to connect the reinforcement layer and the film layer, so that the nylon film has low hydrophilicity, thereby achieving the purpose of using the reinforcement layer to improve the toughness of the nylon film and adding hydrophobic material to the adhesive layer.

[0008] The present invention also provides a method for manufacturing a high-toughness, low-hydrophilicity pure nylon film, which specifically comprises the following steps:

[0009] Step 1: Design the base plate, assembly plate and paving mechanism. There are two assembly plates, which are placed at both ends of the base plate respectively. There are two paving mechanisms, which are installed at both ends of the base plate respectively. The paving mechanism is slidably connected to the base plate. A fixing component is provided at one end of the assembly plate close to the paving mechanism, which is connected to the assembly plate. A pressing component and a glue injection component are provided on the paving mechanism, which are connected to the paving mechanism;

[0010] Step 2: Place the reinforcement layer on the assembly plate equipped with a turning mechanism, and place the roll wrapped with the film layer on the paving mechanism;

[0011] Step 3: Pull out the film layer and pass it through the glue injection component to form an adhesive layer on one side of the film layer. The film layer that has passed through the glue injection component is fixed to the reinforcement layer using a fixing component.

[0012] Step 4: The paving mechanism moves on the bottom plate, and the pressing component contacts the assembly plate, tightly connecting the film layer and the reinforcement layer. The paving mechanism moves to the end face of the assembly plate, and the film layer and the reinforcement layer are bonded and fixed with a buckling plate. After the paving is completed, the film layer is cut using a cutting mechanism;

[0013] Step 5: The flipping mechanism moves, flipping one assembly plate over and placing it on the other assembly plate, releasing the fixing mechanism and the pressing plate, allowing the nylon film to fall on the other assembly plate;

[0014] Step 6: Use the laying mechanism, fixing components and pressing components on another assembly board to bond the other side of the reinforcement layer to the film layer. After bonding, use the cutting mechanism to cut it and the assembly is completed.

After cutting is completed, the flipping mechanism drives the assembly plate to flip, and flips one of the assembly plates to the other assembly plate.

[0054] like Figure 13As shown, a cutting mechanism 8 is provided on the base plate 2, and the cutting mechanism 8 includes a sliding block 2 81, a motor 3 83, and a screw rod 2 84. A sliding groove 23 is provided on the base plate 2, and the sliding groove 23 is placed between the two assembly plates 3. The sliding block 2 81 is slidably connected to the base plate 2 by cooperating with the sliding groove 23. The motor 3 83 is installed on the base plate 2, and the screw rod 2 84 passes through the sliding block 2 81 and is threadedly connected to the sliding block 2 81. One end of the screw rod 2 84 is connected to the motor shaft of the motor 3 83, and the other end of the screw rod 2 84 is provided with a support seat 87, which is connected to the base plate 2, and the screw rod 2 84 is rotatably connected to the support seat 87. A cutting piece 86 is provided on the sliding block 2 81, and the cutting piece 86 is connected to the sliding block 2 81.

[0055] A rotating plate 82 is provided on the top surface of the second sliding block 81, and both sides of the rotating plate 82 are rotatably connected to the second sliding block 81. Cutting pieces 86 are installed on both sides of the rotating plate 82, and the cutting pieces 86 are connected to the rotating plate 82. Baffles 44 are provided on both side surfaces of the second sliding block 81, and the baffles 44 are connected to the second sliding block 81, and the baffles 44 match the rotating plate 82.

[0056] When in use, the reinforcing layer 12 of the nylon film has a mesh structure. The reinforcing layer 12 is made of an elastic material, such as rubber, latex and other materials. The reinforcing layer 12 has a certain elasticity and is a mesh structure. When the nylon film is subjected to force, the mesh structure of the reinforcing layer 12 can disperse the force and make the force uniform, thereby improving the toughness of the nylon film. The film layer 1 made of pure nylon film bonded on both sides of the reinforcing layer 12 provides the nylon film with film properties. The reinforcing layer 12 and the film layer 1 are bonded with an adhesive to form an adhesive layer 11. A hydrophobic agent is added to the adhesive to make the formed adhesive layer 11 hydrophobic, thereby making the nylon film have low hydrophilicity.

[0057] During manufacturing, the reinforcement layer 12 is placed on one of the assembly plates 3, and the film layer 1 is placed on the roller 43 of the paving mechanism 4. When the film layer 1 is pulled out, the roller 43 rolls in the groove 42 of the support plate 41 on the paving mechanism 4, and one end of the film layer 1 passes through the glue injection component 5. The film layer 1 is fixed together by the extrusion block 53 and the wiping block 51. The extrusion block 53 squeezes the film layer 1 under the drive of the pneumatic cylinder 54, and the glue injection tube 52 injects glue into the wiping block 51 through the glue injection hole 55. The adhesive layer 11 is formed on one side of the film layer 1 as the film layer 1 is pulled. One end of the film layer 1 is fixed by the fixing component 7. The fixing plate 71 is rotated to make the inner side surface of the fixing plate 71 parallel to the assembly plate 3. The rotating rod 77 of the screw rod 1 76 is rotated to drive the connection between the connecting rod 1 75 and the connecting rod 2 76 to the side of the fixing plate 71 with one end of the screw rod 1 76, thereby driving the pressure plate 72 to fall, thereby fixing the film layer 1 and the reinforcing layer 12.

[0058] After one end of the fixed film layer 1 is connected to the reinforcing layer 12, the paving mechanism 4 moves on the base plate. The rotation of the motor 45 drives the gear 46 to rotate, and the engagement of the gear 46 with the rack 22 drives the paving mechanism 4 to move. At the same time, the roller 43 rotates to pave the film layer 1 on the reinforcing layer 12. After paving the film layer 1, the clamping assembly 6 on the paving mechanism 4 is activated. Driven by the pneumatic cylinder 2 63, the lifting rod 62 falls, and the pneumatic cylinder 2 63 is rotatably connected to the lifting rod 62. The lifting rod 62 drives the rolling shaft 61 to descend and contact the film layer 1. As the rolling shaft 61 moves, the film layer 1 is tightly bonded to the reinforcing layer 12, and at the same time, it can ensure flatness.

[0059] After one side is paved, the pressing plate 31 is fixed to the end of the assembly plate 3 away from the paving mechanism 4 using pins 33. Simultaneously, the paving mechanism 4 is reset. At this point, the cutting mechanism 8, driven by the rotation of the motor 3 83, rotates the screw 2 84, driving the meshed sliding block 81 within the sliding groove 23. The rotating plate 82 is rotated so that it lands on the baffle 85. The cutting piece 86 follows the sliding block 81 and cuts through the film layer 1. After cutting is complete, the assembly plate 3 is flipped over to another assembly plate 3 by the flipping mechanism 9. After flipping, the fixing assembly 7 and the pressing plate 31 are released, allowing the nylon film to land on the assembly plate 3.

[0060] On another assembly plate 3, the other side of the film layer 1 is laid in the same manner as the previous side. Once both sides are laid, the production of the nylon film is completed.
