DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] This embodiment discloses a film material composite device, as Figures 1-3As shown in the figure, it includes a coating device and a material leveling device. Among them, the coating device is used to coat the adhesive between two layers of film materials 6. The adhesive used is a fluid adhesive, which is coated between the two layers of film materials 6. By extruding the film materials 6, the adhesive can flow to a certain extent between the two layers of film materials 6, and then during the drying process, it gradually cures to bond the film materials 6 on both sides together.

[0029] Among them, the material leveling device can adjust and level the surface of the film material 6. It can face the surface of the film material 6, and in the pressing state, it can scrape the surface of the film material 6, so that the adhesive between the film materials 6 can have a small amount of flow adjustment along the width direction of the fabric, thereby reducing the occurrence of air pockets between the film materials 6 in the unbonded state. Through the material leveling device, the distribution uniformity of the adhesive between the film materials 6 can be improved. When the adhesive flows through the surface of the film material 6, part of the adhesive will adhere to the surface of the film material 6, enabling the two layers of film materials 6 to be bonded, and enabling the two layers of film materials 6 to be bonded with less adhesive.

[0030] Currently, during the bonding process, the surface of the film material 6 is coated with an adhesive far exceeding the required amount, and then through extrusion, the adhesive can flow between the film materials 6 during the extrusion process, so that the space between the film materials 6 can be completely covered by the adhesive, ensuring that the film materials 6 on both sides can be completely bonded together. During the extrusion process, the excess adhesive will overflow from the edge position of the film material 6, resulting in waste of the adhesive.

[0031] By using the material leveling device in this embodiment to extrude the two layers of film materials 6 after coating and lamination, and performing extrusion and leveling in the width direction of the film material 6, the flow distance of the adhesive in the width direction of the film material 6 is increased, thereby reducing the coating amount of the adhesive between the film materials 6 and reducing the waste of the adhesive.

[0032] The material leveling device includes a first pressure roller 1, a second pressure roller 2 and a material leveling component 7. The first pressure roller 1 abuts against the second pressure roller 2. The first layer of film material 6 and the second layer of film material 6 after coating are mutually adhered. After being guided by the guide roller 5, they pass between the first pressure roller 1 and the second pressure roller 2. By extruding the two layers of film materials 6 through the first pressure roller 1 and the second pressure roller 2, the adhesive between the two layers of film materials 6 will also flow to a certain extent, so that the adhesive can be evenly distributed between the two layers of film materials 6, improving the uniformity after subsequent bonding.

[0033] The material leveling assembly 7 includes a transverse movement mechanism 4 and a scraping mechanism 3. Among them, the scraping mechanism 3 has a flexible pressing part, specifically a scraping blade 35, which can abut against the surface of the film material 6 wound around the first pressing roller 1; the scraping mechanism 3 is driven by the transverse movement mechanism 4 to move transversely and can move along the axial direction of the first pressing roller 1. The scraping blade 35 moves in a state of abutting against the surface of the film material 6, so that the adhesive between the film material pieces can flow in the width direction, compensating for the extrusion of the pressing roller, and thus reducing the amount of adhesive used between the film materials 6.

[0034] As Figure 2 shown, the transverse movement mechanism 4 is in a form similar to belt drive to achieve transmission. Specifically, it includes an endless belt 41 and several transmission wheels 42. The endless belt 41 is rotationally supported by the transmission wheels 42, and the endless belt 41 can achieve circular transmission. One side of the endless belt 41 faces the direction of the first pressing roller 1, and the transmission direction of the endless belt 41 is parallel to the axial direction of the pressing roller. During the circular motion of the endless belt 41, one side of the endless belt 41 will move along the axial direction of the pressing roller, thereby driving the scraping mechanism 3 to generate a transverse movement.

[0035] In the material leveling assembly 7, several groups of scraping mechanisms 3 are provided. Each group of scraping mechanisms 3 is installed on the endless belt 41 and forms a uniformly distributed state. During the operation of the material leveling assembly 7, the scraping blades 35 of multiple scraping mechanisms 3 simultaneously abut against the surface of the film material 6 on the first pressing roller 1, thereby increasing the density of scraping in the width direction of the film material 6. Through the rotation of the endless belt 41, the scraping mechanism 3 can abut against the first pressing roller 1 and move along the axial direction of the first pressing roller 1. Each scraping blade of the scraping mechanism 3 scrapes the surface of the film material 6, driving the adhesive of the film material pieces to flow along the axial direction and increasing the attachment position of the adhesive.

[0036] As Figure 3 shown, the scraping mechanism 3 includes a scraping seat and a scraping blade 35. With the scraping seat as the support, the scraping blade 35 is installed on the scraping seat, and the scraping seat is installed on the transverse movement mechanism 4. Specifically, the scraping seat is installed on the endless belt 41. The endless belt 41 can adopt a metal chain-like structure to increase its support strength.

[0037] In the scraping mechanism 3, the scraping blade 35 is an elastic rubber sheet, and the scraping blade 35 can abut against the outer peripheral surface of the first pressing roller 1. When the scraping blade 35 is pressed by the first pressing roller 1, the scraping blade 35 can bend into an arc shape and fit and press against the first pressing roller 1 along the circumferential direction of the first pressing roller 1; when the scraping blade 35 rotates to the side away from the first pressing roller 1 with the endless belt 41, the scraping blade 35 will separate from the first pressing roller 1, and the scraping blade 35 will elastically return to a flat state again. With the elasticity of the scraping blade 35, the flatness when fitting against the first pressing roller 1 and the surface of the film material 6 can be increased, and the pushing effect on the adhesive between the film materials 6 can be improved.

[0038] Furthermore, both ends of the scraping blade 35 adopt a movable structure and are connected to the scraping seat by a sliding connection structure. Specifically, sliding rails 32 are fixedly connected to both sides of the scraping seat, and sliding seats 33 are slidably connected to the sliding rails 32. The two sliding rails 32 are coaxial, and both ends of the scraping blade 35 are respectively installed on the two sliding seats 33. Through the relative movement of the two sliding seats 33, the two ends of the scraping blade 35 can produce applicable activities, and a concave bending deformation action can be formed at the middle position of the scraping blade 35, so that the scraping blade 35 can be smoothly pressed against the surface of the film material 6 and the first pressing roller 1.

[0039] When the scraping blade 35 abuts against the first pressing roller 1, the two sliding seats 33 move towards each other, the two ends of the scraping blade 35 approach each other, and the scraping blade 35 bends into a shape that fits the surface of the first pressing roller 1.

[0040] In addition, connection seats 34 are installed at both ends of the scraping blade 35, and the connection seats 34 are located on the side facing the annular belt 41. The two connection seats 34 are respectively rotatably connected to the two sliding seats 33. Through the relative rotation between the connection seats 34 and the sliding seats 33, the two ends of the scraping blade 35 can also rotate relatively. When the scraping blade 35 fits the arc of the surface of the first pressing roller 1, the contour of the scraping blade 35 can fit the shape of the first pressing roller 1 more closely, improving the flatness of the pressing against the surface of the film material 6 and the even material effect of the bonding of the film material 6.

[0041] As Figure 3 shown, in order to increase the stability of the scraping blade 35, the scraping blade 35 is guided by a guide rod 36 between the scraping blade 35 and the base 31, so that only the middle section of the scraping blade 35 can float, avoiding the situation that the whole scraping blade 35 slides along the sliding rail 32 and generates deviation.

[0042] A guide rod 36 is fixedly connected to the side of the scraping blade 35 facing the base 31, and the guide rod 36 is perpendicular to the axis of the first pressing roller 1. A guide hole 37 is formed on the base 31, and the guide rod 36 is slidably connected in the guide hole 37 and can move relatively closer to or farther away from the direction of the first pressing roller 1, so that the middle position of the scraping blade 35 does not follow the sliding seat 33 to generate a sliding movement. In addition, a spring 38 is installed between the bottom of the guide hole 37 and the guide rod 36. Through the elastic pressing action of the spring 38, when the scraping blade 35 abuts against the pressing roller, it has a greater elastic force, thereby increasing the fitting degree of the scraping blade 35 with the film material 6 and the first pressing roller 1 and improving the scraping evenness effect of the binder of the film material 6.

[0043] This embodiment also discloses a film material composite device. On the basis of the above embodiment, with reference to Figures 4-8In this embodiment, the material leveling assembly 7 is provided with two groups, namely the first material leveling assembly and the second material leveling assembly, which are respectively located on both sides of the circumference of the pressure roller 1, and can be located on the upper and lower sides respectively.

[0044] Press roller 1 includes a first end 11, a second end 12, and a middle portion 13. A first material-scraping assembly is located at the first end 11 of press roller 1. Its scraper blade 35 abuts against press roller 1 and is capable of scraping material axially from the first end 11 toward the second end 12. A second material-scraping assembly is located at the second end 12 of press roller 1. Its scraper blade 35 abuts against press roller 1 and is capable of scraping material axially from the second end 12 toward the first end 11. The first and second material-scraping assemblies push adhesive near the ends toward the middle portion 13, concentrating the adhesive bond near the middle portion 13 of press roller 1, i.e., the center of the wide width of the film 6. This minimizes adhesive overflow from the edges of the film 6 and reduces adhesive loss.

[0045] After passing through the material leveling assembly 7, the film material 6 will once again pass through the pressing position of the pressure roller 1 and the pressure roller 2, where the film material 6 will be further squeezed. Under the squeezing action of the film material 6, the adhesive between the film materials 6 will once again flow. Since the adhesive in the middle portion 13 of the film material 6 is relatively large, the adhesive in the middle portion 13 will flow toward both sides of the wide width of the film material 6. During the circulation process, the adhesive can pass through the surface of the film material 6 as much as possible, thereby ensuring that the adhesive can be fully adhered between the films and improving the bonding stability between the two layers of film material 6.

[0046] Furthermore, a plurality of grooves 101 are formed on the outside of the middle portion 13 of the pressure roller 1. The grooves 101 are arranged along the axial direction of the pressure roller 1 and are arranged in an annular pattern around the outer circumference of the pressure roller 1. An arc 102 is formed between adjacent grooves 101. When the film 6 passes through the middle portion 13, the grooves 101 in the middle portion 13 can reduce the pressure on the film 6, allowing the film 6 to slightly bulge toward the grooves 101. This reduces the pressure between the film 6 and the pressure roller 1 at the middle portion 13, allowing more adhesive to be accommodated between the film 6.

[0047] As the film 6 passes through the material leveling assembly 7, it pushes the adhesive along the width of the film 6, allowing more of the adhesive to be placed in the center of the film 6, corresponding to the center portion 13 of the pressure roller 1. Then, when the film 6 passes again between the pressure rollers 1 and 2, the adhesive is squeezed and circulated again, increasing the adhesive's adhesion rate to the film 6 and improving bonding stability.

[0048] This embodiment discloses a film material 6 composite process, which can use the film material composite equipment in the above embodiment. First, a coating device is used to coat an adhesive between two layers of film materials 6, so that a certain amount of adhesive can adhere to the surface of the film materials 6. Then, the two mutually adhered film materials 6 pass around a material leveling device, and the material leveling device can adjust the adhesive on the film materials 6 in the width direction. The material leveling device scrapes the film materials 6 in the width direction, so that the adhesive coated between the film materials 6 can flow in the width direction of the film materials 6, increasing the adhesion area between the adhesive and the film materials 6, improving the adhesion rate of the adhesive to the film material 6 parts, and improving the adhesion stability.

[0049] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
