Description

Technical Field

[0001] The present invention relates to the technical field of film material processing, and specifically relates to a film material composite device and process. Background Art

[0002] A film material is a material used in membrane structure engineering, which is a composite material composed of a high-strength fabric substrate and a polymer coating. The coating protects the substrate and forms the sealing performance of the film material.

[0003] Chinese invention with publication number CN117601551A discloses a film material composite device and a film material composite process, which can perform extrusion and material leveling in the width direction of the film material, increase the flow distance of the binder in the width direction of the film material, and thus can reduce the coating amount of the binder between the film materials and reduce the waste of the binder.

[0004] However, in actual use, for film materials with relatively thin thickness and low self-strength, the extrusion force on the film material in the width direction is likely to cause a large degree of deformation of the film material itself, resulting in an increase in the width size of the film material, and even causing the film material to be torn during the deformation process, seriously affecting the performance of the film material. Therefore, the present invention provides a film material composite device and process to solve the above problems. Summary of the Invention

A coating roller is arranged on the outside of the film material body, and the coating roller presses the film material body and the pressing belts;

[0008] A plurality of annular grooves are formed on the surface of the coating roller at equal intervals, and the annular grooves on the two coating rollers are staggered with each other.

[0009] An arc-shaped inner lining is fixed on the inner side wall of the dust-proof cover, and a plurality of material holes are formed through the inner wall of the arc-shaped inner lining at equal intervals. A hollow tube is fixed on the outside of the dust-proof cover, and the material holes communicate with the inner cavity of the hollow tube. The plurality of material holes respectively correspond to the plurality of annular grooves one by one.

[0010] Preferably, anti-deviation retaining rings are fixedly sleeved on the outer sides of both ends of the coating roller, and the arc-shaped inner lining is located between the two anti-deviation retaining rings. A plurality of arc-shaped cushion layers are adhesively bonded to the inner wall of the arc-shaped inner lining and are distributed at equal intervals, and the plurality of arc-shaped cushion layers and the plurality of material holes are staggered and spaced apart. The inner wall of the arc-shaped cushion layer is attached to the surface of the coating roller. A bonding agent pipe for feeding the hollow pipe is communicated with the outside of the hollow pipe.

[0011] Preferably, driving rollers are arranged on the inner sides of both ends of the pressing belt. Positioning brackets are arranged on both sides of the pressing belt. The positioning bracket is composed of two "cross"-shaped brackets spliced and fixed horizontally. The two ends of the rotating shaft of the driving roller are respectively rotatably connected to the two positioning brackets.

[0012] Preferably, a protective cover is arranged above the two positioning brackets. The protective cover is in a "C" shape with an opening downward and covers the outside of the pressing belt and the film material body. The two sides of the protective cover are fixedly connected to the two positioning brackets through connecting rods respectively, and a gap is left between the lower end of the protective cover and the dust cover.

[0013] Preferably, a limiting sliding groove corresponding to the coating roller is formed on the surface of the positioning bracket. A square sliding sleeve adapted to it is slidably installed in the inner cavity of the limiting sliding groove, and the square sliding sleeve is rotatably sleeved on the end of the rotating shaft of the coating roller through a bearing. A connecting block is fixedly connected to one side surface of the square sliding sleeve, and the connecting block is fixedly connected to the end of the dust cover.

[0014] Preferably, an elastic telescopic member is installed on the surface of the connecting block, and one end of the elastic telescopic member abuts against the inner wall of one end of the limiting sliding groove. The elastic telescopic member is a telescopic rod with a built-in spring.

[0033] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by referring to examples. In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily making these embodiments difficult to understand. Additionally, all embodiments can be used in combination with each other.

[0034] Please refer to Figures 1 to 9 , the present invention provides a technical solution:

[0035] Embodiment 1, a film material composite device, including: a pressing belt 1.

[0036] Specifically, there are two pressing belts 1 which are symmetrically distributed. The surface of the pressing belt 1 is semi-coated and fitted with the film material body 2, and one end of the two film material bodies 2 is squeezed and fitted between the two pressing belts 1. As Figure 1 shown, the pressing belt 1 is vertically arranged. When the film material body 2 is conveyed, the pressing belt 1 can be conveyed and driven along with it through the frictional force between the pressing belt 1 and the film material body 2. Since the two pressing belts 1 are close to each other, the two pressing belts 1 can squeeze the two film material bodies 2 against each other, so that the two film material bodies 2 are bonded and compounded together. And because when the pressing belt 1 squeezes the film material body 2, the contact area between the pressing belt 1 and the film material body 2 is large. On the one hand, it can improve the bonding and compounding effect of the two film material bodies 2. On the other hand, it can avoid the film material body 2 being deformed or even torn due to excessive local stress. A coating roller 3 is arranged outside the film material body 2, and the coating roller 3 presses the film material body 2 and the pressing belt 1. As Figure 2 shown, while the coating roller 3 presses the film material body 2, it can also press the pressing belt 1, so that the side where the two pressing belts 1 are close to each other can always be kept in a taut state. Then, the two film material bodies 2 are squeezed and compounded by the taut part of the pressing belt 1, thereby improving the bonding and compounding effect of the two film material bodies 2;

[0037] Secondly, a plurality of annular grooves 31 are arranged on the surface of the coating roller 3 at equal intervals, and the annular grooves 31 on the two coating rollers 3 are staggered with each other. The inner cavity of the annular groove 31 is filled with an adhesive. Combining Figure 3 and Figure 8 it can be known that when the coating roller 3 rotates with the conveyance of the film material body 2, the coating roller 3 can coat the adhesive filled in the inner cavity of the annular groove 31 on the surface of the film material body 2, and the adhesive is in the shape of a plurality of long strips distributed at equal intervals on the surface of the film material body 2. When the two film material bodies 2 approach each other, as Figure 9 shown, the long strip adhesives on the surfaces of the two film material bodies 2 can just be staggered with each other. When the two film material bodies 2 are squeezed and compounded with each other, the adhesive is slightly deformed and spread out under extrusion, so as to fill the gap between the two film material bodies 2 and improve the compounding effect of the two film material bodies 2. Tooth grooves 32 are arranged at the bottom of the annular groove 31. A dust-proof cover 4 concentric with it is arranged outside the coating roller 3. The tooth grooves 32 are used to increase the contact area between the bottom of the annular groove 31 and the adhesive, ensuring that the adhesive can be stably retained in the inner cavity of the annular groove 31. When the coating roller 3 rotates, the adhesive in the inner cavity of the annular groove 31 will not be easily thrown out. Only when the adhesive contacts the surface of the film material body 2, the adhesive will be coated on the surface of the film material body 2. The dust-proof cover 4 can protect the coating roller 3 to prevent dust from falling on the surface of the coating roller 3 and affecting the viscosity of the adhesive;

[0038] Furthermore, an arc-shaped inner lining 41 is fixed to the inner side wall of the dust cover 4, and a plurality of material holes 43 are formed through the inner wall of the arc-shaped inner lining 41 at equal intervals. A hollow tube 42 is fixed to the outer side of the dust cover 4, and the material holes 43 communicate with the inner cavity of the hollow tube 42. The plurality of material holes 43 respectively correspond to the plurality of annular grooves 31 one by one. As Figure 4 and Figure 5 shown, the adhesive in the inner cavity of the hollow tube 42 can be extruded from the material holes 43 under the action of pressure, and then filled into the inner cavity of the annular groove 31. As the coating roller 3 rotates, the inner cavity of the annular groove 31 can be completely filled with the adhesive. The setting of the arc-shaped inner lining 41 is closer to the surface of the coating roller 3 relative to the dust cover 4, so as to prevent the adhesive in the inner cavity of the annular groove 31 from overflowing.

[0039] In order to prevent the surface of the coating roller 3 from adhering to the adhesive, the present application also has anti-deviation retaining rings 33 fixedly sleeved on the outer sides of both ends of the coating roller 3, and the arc-shaped inner lining 41 is located between the two anti-deviation retaining rings 33. The anti-deviation retaining rings 33 are used to position the film body 2 and prevent the film body 2 from shifting in its own width direction. A plurality of arc-shaped cushions 44 are adhesively bonded to the inner wall of the arc-shaped inner lining 41 at equal intervals, and the plurality of arc-shaped cushions 44 are staggered and spaced apart from the plurality of material holes 43. The inner wall of the arc-shaped cushion 44 is in contact with the surface of the coating roller 3. As Figure 4 shown, the arc-shaped cushion 44 remains in contact with the surface of the coating roller 3, and can be used to wipe a little adhesive escaping from the inner cavity of the annular groove 31 to prevent the adhesive from adhering to the surface of the coating roller 3. A adhesive material pipe 5 for supplying material to the hollow tube 42 is communicated with the outer side of the hollow tube 42. The adhesive material pipe 5 is used to transport the external adhesive to the inner cavity of the hollow tube 42 and provide a certain pressure to extrude the adhesive from the inner cavity of the material hole 43 and fill it into the inner cavity of the annular groove 31.

[0040] In order to position the pressing belt 1, the present application also has driving rollers 101 provided on the inner sides of both ends of the pressing belt 1, which are used to support the pressing belt 1 and ensure that the pressing belt 1 can perform conveying and driving by itself. Combining Figure 2 shown, the coating roller 3 is located outside the middle of the film body 2. When the coating roller 3 presses one side of the film body 2, the other side of the film body 2 can remain taut. Positioning brackets 7 are provided on both sides of the pressing belt 1. The positioning brackets 7 are formed by splicing two "cross"-shaped brackets horizontally and fixedly. The rotating shafts at both ends of the driving roller 101 are respectively rotatably connected to the two positioning brackets 7. The positioning brackets 7 are mainly used to position the driving roller 101 to prevent the pressing belt 1 from shifting.

[0041] To prevent dust from adhering to the adhesive on the surface of the film body 2, the present application further has a protective cover 9 disposed above between the two positioning brackets 7. The protective cover 9 is in a "C" shape with an opening downward and covers the outer sides of the pressing belt 1 and the film body 2. As Figure 1 shown, after the film body 2 is coated with the adhesive by the coating roller 3, the protective cover 9 can prevent dust from adhering to the coated part of the film body 2, avoiding the influence of dust adhesion on the adhesive on the subsequent composite effect of the film body 2. Both sides of the protective cover 9 are fixedly connected to the two positioning brackets 7 through connecting rods respectively for positioning the protective cover 9. A gap is left between the lower end of the protective cover 9 and the dust-proof cover 4 to prevent collision between the dust-proof cover 4 and the protective cover 9.

[0042] To install the coating roller 3 and the dust-proof cover 4, the present application further has a limit sliding groove 71 corresponding to the coating roller 3 opened on the surface of the positioning bracket 7. A square sliding sleeve 6 adapted thereto is slidably installed in the inner cavity of the limit sliding groove 71, and the square sliding sleeve 6 is rotatably sleeved on the end of the rotating shaft of the coating roller 3 through a bearing. As Figure 4 and Figure 6 shown, the square sliding sleeve 6 can only slide along the length direction of the limit sliding groove 71 in the inner cavity of the limit sliding groove 71. When the square sliding sleeve 6 slides, the position of the coating roller 3 itself can be adjusted accordingly. A connecting block 61 is fixedly connected to one side surface of the square sliding sleeve 6, and the connecting block 61 is fixedly connected to the end of the dust-proof cover 4. The connecting block 61 connects the square sliding sleeve 6 and the dust-proof cover 4, thereby realizing the positioning of the dust-proof cover 4 and ensuring that the relative positions between the coating roller 3 and the dust-proof cover 4 will not change.

[0043] To push the coating roller 3 to move, the present application further has an elastic telescopic member 62 installed on the surface of the connecting block 61, and one end of the elastic telescopic member 62 abuts against one end inner wall of the limit sliding groove 71. The elastic telescopic member 62 is a telescopic rod with a built-in spring. As Figure 6 shown, the spring built in the elastic telescopic member 62 can provide elastic force to push the coating roller 3 to slide, so that the two coating rollers 3 always have a tendency to approach each other, thereby always squeezing the film body 2 to ensure that the film body 2 always remains in a taut state.

[0044] To scrape off the adhesive adhering to the edge of the surface of the pressing belt 1, the present application further has a connecting frame 72 fixedly connected to the lower end of the positioning bracket 7 through bolts. One end of the connecting frame 72 is fixedly installed with a scraper 73 through bolts. An arc-shaped groove 731 is opened on one side of the scraper 73 and fits the outer surface at the lower end of the pressing belt 1. The scraper 73 is inclined at an angle of forty-five degrees along the axial direction of the driving roller 101. As Figure 7 and Figure 1As shown, the squeegee 73 is located at the side edge of the pressing belt 1. When the pressing belt 1 presses and composites the film body 2, causing some adhesive to overflow from between the two film bodies 2, due to the relatively thin thickness of the film body 2 itself, the overflowed adhesive will be squeezed by the pressing belt 1 and adhere to the edge of the surface of the pressing belt 1. With the conveying and driving of the pressing belt 1, the squeegee 73 can scrape the adhesive adhering to the surface of the pressing belt 1. And because the squeegee 73 is inclined, the adhesive can be prevented from adhering to the surface of the pressing belt 1 again after being scraped off.

[0045] In order to wind the composite film body 2, the present application also has a guide roller 10 provided outside the film body 2 to guide its conveying, as Figure 1 and Figure 2 shown. The horizontally conveyed film body 2 is semi-wrapped around the outside of the guide roller 10, is conveyed vertically upward after passing through the guide roller 10, and then is semi-wrapped around the outside of the pressing belt 1. Finally, it is conveyed from top to bottom between the two pressing belts 1. A winding roller 8 is rotatably installed below between the two pressing belts 1, and the winding roller 8 is driven to rotate by an external motor. The two film bodies 2 are bonded and wound around the outside of the winding roller 8. The winding roller 8 is used to wind the two bonded and composite film bodies 2.

[0046] The present invention also discloses a film composite process, in which two film bodies 2 are bonded and composite by using the above-mentioned film composite equipment.

[0047] Although the embodiments of the present invention 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 principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
