Description

Technical Field

[0001] The utility model relates to the technical field of film production equipment, in particular to an anti-wrinkle film attaching air knife structure device. Background Technique

[0002] Before in the film production and processing industry, rollers were used to attach the film to the casting roller and the corona roller. With the continuous improvement of industry technology and the increasingly thin thickness requirements for films in the high-end fields in the market, the previous roller attachment method is no longer applicable and high-quality products cannot be produced. In the film processing industry, the film attachment effect is directly related to the appearance quality and physical properties of the product. In order to improve the accuracy and efficiency of film attachment, the air knife technology, as a non-contact and high-efficiency tool, has gradually been widely used in the film processing field. The film attaching air knife realizes the precise attachment of the film through the air knife effect generated by high-pressure air flow. Its working principle is based on the Coanda effect, that is, when the high-pressure air flow passes through the air outlet, a high-strength air flow sheet will be formed. This air flow sheet can drive a large amount of surrounding air to form a wide and uniform air curtain. This air curtain blows towards the film at a very high speed to ensure that the film is closely attached to the roller. However, the traditional film attaching air knife structure device is inconvenient to adjust the length, width and air volume of the air outlet, and the film is prone to wrinkle during film attachment, resulting in a reduction in the quality of the film. Therefore, there are certain drawbacks.

[0003] To sum up, the utility model solves the existing problems by designing an anti-wrinkle film attaching air knife structure device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-wrinkle film attaching air knife structure device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An anti-wrinkle film attaching air knife structure device includes a box body. A high-pressure blower is installed on the narrower side surface of the outer part of the box body. A through groove is opened at the bottom inside the box body. A conveying pipe is installed on the narrower side wall inside the box body. A support frame is installed at the bottom inside the box body and close to one end of the conveying pipe. An electric push rod is installed on the outer side surface of the support frame. One end of the electric push rod is installed with a mounting plate. A spherical block is installed at the outer end of the mounting plate. An air outlet is installed at the bottom of the box body and located on the through groove. A groove is opened at the bottom edge of the wider side surface of the outer part of the air outlet. Limit blocks are installed on both narrower side walls inside the air outlet.

[0007] A fixing block is installed at one long edge of the bottom of the box body. An adjusting bolt is installed outside the fixing block. One end of the adjusting bolt is installed with a first movable baffle on the groove. Symmetrical sliding grooves are opened on the relatively narrow two side faces of the outside of the first movable baffle. A first support plate is installed at one short edge of the bottom of the box body. A servo motor is installed on the relatively wide side face of the outside of the first support plate. A bidirectional threaded rod is installed on the side face of the outside of the first support plate away from the servo motor. One end of the bidirectional threaded rod away from the first support plate is installed with a second support plate at the bottom of the box body. Movable blocks are symmetrically installed at both ends of the outer ring surface of the bidirectional threaded rod. A second movable baffle is installed at the bottom of the movable block. Support rods are symmetrically installed at both ends of one long edge of the bottom of the box body. A U-shaped frame is jointly installed at the bottom of the support rods. A leveling roller is installed between the inner side walls of the U-shaped frame.

[0008] As a preferred solution of the present utility model, the air outlet pipe of the high-pressure blower extends into the interior of the box body and is connected to the conveying pipe, and the inner side wall diameter of the conveying pipe is smaller than the outer diameter of the spherical block.

[0009] As a preferred solution of the present utility model, one end of the adjusting bolt passes through the fixing block and is rotatably connected to the outside of the first movable baffle, and the outer ring surface of the adjusting bolt is threadedly connected to the inside of the fixing block.

[0010] As a preferred solution of the present utility model, the inner side wall size of the sliding groove matches the outer size of the limiting block, and the inner side wall of the sliding groove is slidably connected to the outside of the limiting block.

[0011] As a preferred solution of the present utility model, one end of the bidirectional threaded rod passes through the first support plate and is connected to the output shaft of the servo motor, and one end of the bidirectional threaded rod away from the first support plate is rotatably connected to the outer side face of the second support plate.

[0012] As a preferred solution of the present utility model, the outer ring surface of the bidirectional threaded rod is threadedly connected to the inside of the two movable blocks. The second movable baffle is slidably connected and closely attached to the bottom of the air outlet, and the second movable baffle and the first movable baffle do not interfere with each other when moving in contact with each other.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. In the present utility model, a wrinkle-proof film attachment air knife structure device is designed. By arranging a flattening roller above the film and synchronously assisting the film to attach to the roller when the air knife blows, wrinkling of the film during adsorption is avoided. As the spherical blocks gradually fit the delivery pipe, the air output of the delivery pipe gradually decreases, thereby realizing the adjustment of the air volume at the air outlet. By arranging a first movable baffle and two second movable baffles to adjust the length and width of the air outlet, the problems that the traditional film attachment air knife structure device is inconvenient to adjust the length, width and air output of the air outlet and the film is prone to wrinkling during film attachment are effectively solved.

[0026] For the embodiments, please refer to Figures 1-6 , the present utility model provides a technical solution:

[0027] An anti-wrinkle film attaching air knife structure device, comprising a box body 1, a high-pressure blower 2 is installed on the narrower side surface of the outside of the box body 1, a through groove 101 is opened at the inner bottom of the box body 1, a conveying pipe 3 is installed on the narrower side wall inside the box body 1, a support frame 4 is installed at one end of the inner bottom of the box body 1 and close to the conveying pipe 3, an electric push rod 5 is installed on the outer side surface of the support frame 4, one end of the electric push rod 5 is installed with a mounting plate 6, a spherical block 7 is installed at the outer end of the mounting plate 6, an air outlet 8 is installed at the bottom of the box body 1 and located on the through groove 101, a groove 801 is opened at the bottom edge of the wider side surface of the outside of the air outlet 8, and limiting blocks 9 are installed on both narrower side walls inside the air outlet 8;

[0028] A fixing block 10 is installed at a longer edge of the bottom of the box body 1. An adjusting bolt 11 is installed outside the fixing block 10. One end of the adjusting bolt 11 is located on the groove 801 and a first movable baffle 12 is installed. Symmetrical sliding grooves 1201 are provided on the relatively narrow two side faces of the outside of the first movable baffle 12. A first support plate 13 is installed at a shorter edge of the bottom of the box body 1. A servo motor 14 is installed on the relatively wide side face of the outside of the first support plate 13. A bidirectional threaded rod 15 is installed on the side face of the outside of the first support plate 13 away from the servo motor 14. One end of the bidirectional threaded rod 15 away from the first support plate 13 is located at the bottom of the box body 1 and a second support plate 16 is installed. Movable blocks 17 are symmetrically installed at both ends of the outer ring surface of the bidirectional threaded rod 15. A second movable baffle 18 is installed at the bottom of the movable block 17. Support rods 19 are symmetrically installed at both ends of a longer edge of the bottom of the box body 1. A U-shaped frame 20 is jointly installed at the bottom of the support rods 19. A leveling roller 21 is installed between the inner side walls of the U-shaped frame 20.

[0029] Specifically, referring to Figure 6 , the air outlet pipe of the high-pressure blower 2 extends into the inside of the box body 1 and is connected to the conveying pipe 3, and the inner diameter of the inner side wall of the conveying pipe 3 is smaller than the outer diameter of the spherical block 7, so that it is convenient to drive the spherical block 7 to approach the conveying pipe 3 by the electric push rod 5. When the spherical block 7 gradually fits the conveying pipe 3, the air output of the conveying pipe 3 gradually decreases, so as to realize the air volume adjustment of the air outlet 8.

[0030] Further, one end of the adjusting bolt 11 passes through the fixing block 10 and is rotatably connected to the outside of the first movable baffle 12, and the outer ring surface of the adjusting bolt 11 is threadedly connected to the inside of the fixing block 10, so as to ensure that the first movable baffle 12 is driven by the adjusting bolt 11 to slide inside the groove 801, so as to slide inside the air outlet 8 to adjust the width of the air outlet 8.

[0031] Further, the inner side wall size of the sliding groove 1201 matches the outer size of the limiting block 9, and the inner side wall of the sliding groove 1201 is slidably connected to the outside of the limiting block 9, so as to ensure that the sliding groove 1201 slides along the limiting block 9 synchronously when the first movable baffle 12 slides inside the groove 801, thereby increasing the stability of the movement and adjustment of the first movable baffle 12.

[0032] Further, one end of the bidirectional threaded rod 15 passes through the first support plate 13 and is connected to the output shaft of the servo motor 14, and one end of the bidirectional threaded rod 15 away from the first support plate 13 is rotatably connected to the outer side face of the second support plate 16, so as to ensure that the bidirectional threaded rod 15 is driven to rotate by the servo motor 14.

[0033] Specifically, referring to such as Figure 3, the outer ring surface of the bidirectional threaded rod 15 is threadedly connected to the inside of the two movable blocks 17. The second movable baffle 18 is slidably connected and closely attached to the bottom of the air outlet 8, and when the second movable baffle 18 and the first movable baffle 12 move in contact with each other, they do not interfere with each other. Thus, it is ensured that the two movable blocks 17 move relatively driven by the movement of the bidirectional threaded rod 15, so as to drive the two second movable baffles 18 to slide along the bottom of the air outlet 8, thereby realizing the length adjustment of the air outlet 8.

[0034] The working process of the present utility model: When using the anti-wrinkle film attaching air knife structure device designed by this solution to attach the film to the film during film production, first install the device above the conveying roller. The high-pressure blower 2 conveys air into the inside of the box body 1, and the air forms an air knife through the air outlet 8 and is discharged to blow the film below, so that the film is evenly attached to the roller. By setting the leveling roller 21 to fit above the film and assisting the film to be attached to the roller synchronously when the air knife blows, wrinkles generated during film adsorption are avoided. The electric push rod 5 drives the spherical block 7 to approach the conveying pipe 3. When the spherical block 7 gradually fits the conveying pipe 3, the air output of the conveying pipe 3 gradually decreases, thereby realizing the air volume adjustment of the air outlet 8. The adjusting bolt 11 drives the first movable baffle 12 to slide inside the groove 801, so as to slide inside the air outlet 8 to adjust the width of the air outlet 8. When the first movable baffle 12 slides inside the groove 801, the sliding groove 1201 slides along the limiting block 9 synchronously, thereby increasing the stability of the movement adjustment of the first movable baffle 12. The servo motor 14 drives the bidirectional threaded rod 15 to rotate, and the bidirectional threaded rod 15 moves to drive the two movable blocks 17 to move relatively, so as to drive the two second movable baffles 18 to slide along the bottom of the air outlet 8, thereby realizing the length adjustment of the air outlet 8. Thus, by adjusting the length and width of the air outlet 8 and the air output of the air outlet 8, the practicability of the device is increased, and the applicable range is wider.

[0035] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
