Description

Technical Field

[0001] This application relates to the field of composite material compaction device technology, and in particular to a composite material adhesive fiber fabric compaction device. Background Technology

[0002] In industries such as apparel and home textiles, it is often necessary to laminate adhesive films, such as PET films, with fabrics like fibers, cotton, or linen. For example, in apparel production, cotton and linen fabrics are laminated with other functional adhesive film fabrics to increase the warmth and water resistance of the garments. Similarly, in home textile products, such as wallpaper, cotton and linen fibers are laminated with adhesive films during the manufacturing process to enhance the texture and strength of the wallpaper, resulting in better decorative effects and durability.

[0003] In the composite production process of adhesive film and fabric, the fabric is usually first laid on the adhesive film, and then the fabric and adhesive film are compacted by a compaction device. Currently, common compaction devices mostly use roller tools such as rubber rollers or steel rollers to roll and compact the fabric and adhesive film. For example, the utility model patent with publication number CN213923417U discloses a multi-layer fabric leveling device for uniform compaction. This device is equipped with a pressing compaction roller A and a pressing compaction roller B. When the fabric is compacted, the fabric passes between the pressing compaction roller A and the pressing compaction roller B, and the pressing compaction roller A and the pressing compaction roller B squeeze the fabric to achieve the compaction and composite of multi-layer fabric.

[0004] However, the above-mentioned compacted multi-layer fabric leveling device uses a compaction roller for compaction and bonding. Although it has a relatively uniform rolling pressure and can achieve a better bonding effect, the friction between the compaction roller and the fabric surface is small. For areas with unevenness or wrinkles on the fabric surface, the leveling effect is not good. These defects on the fabric surface may still exist after compaction, thus affecting the bonding effect. Utility Model Content

[0005] The purpose of this application is to provide a compaction device for composite material film fiber fabric, which solves the problem that in related technologies, the fabric leveling device uses a compaction wheel for compaction and composite, and the leveling effect is not good for the defective parts of the fabric surface that are uneven or wrinkled. These defects may still exist on the fabric surface after compaction, thus affecting the composite effect.

[0006] The technical solution of the composite material film fiber fabric compaction device provided in this application is as follows: A compaction device for adhesive film fiber fabric for composite materials, comprising: Support components; A leveling mechanism includes a scraper and a support plate disposed on the support member. The scraper is disposed above the support plate and is used to level the upper surface of the fabric. The support plate is used to support the fabric and adhesive film passing under the scraper. The pressing mechanism includes a fixed roller, a movable roller, and an elastic element disposed on the support member. The elastic element acts on the movable roller and is used to provide a spring force to push the movable roller toward the fixed roller. The fixed roller and the movable roller are used to roll the fabric and adhesive film after they have been flattened by the scraper.

[0007] Optionally, the leveling mechanism further includes a bracket and a height adjustment component. The bracket is vertically adjustable on the support member. The scraper and the height adjustment component are mounted on the bracket. The scraper has multiple blades, each with a different hardness. The height adjustment component is used to adjust the height of each of the multiple scraper blades.

[0008] Optionally, the height adjustment assembly includes a lifting drive and a vertical sliding seat. The vertical sliding seat is slidably mounted on the bracket, the lifting drive is mounted on the bracket and connected to the vertical sliding seat, and the multiple scrapers are detachably connected to the vertical sliding seat via connectors.

[0009] Optionally, the connector is a connecting bolt, the scraper is provided with a slide block, the scraper is slidably mounted on the bracket via the slide block, the slide block is provided with a connecting hole, the vertical moving seat is provided with a connecting screw hole, the connecting bolt is screwed into the connecting screw hole, and can be inserted into the connecting hole.

[0010] Optionally, the leveling mechanism further includes a fixing member, which is used to fix the scraper to the bracket after the scraper is separated from the vertical moving seat.

[0011] Optionally, the pressing mechanism further includes a pressure adjusting component, the elastic element being a pressing spring, the pressure adjusting component being disposed on the support member, the pressure adjusting component being able to act on the pressing spring and being used to adjust the extension and retraction of the pressing spring.

[0012] Optionally, the pressing mechanism further includes a roller frame, the pressure adjusting assembly includes a pushing member and a pressure plate, the pressure plate and the roller frame are slidably mounted vertically on the support member, the movable roller is rotatably mounted on the roller frame, the pressing spring is disposed between the pressure plate and the roller frame, the pushing member is disposed on the support member and is used to push the pressure plate to move toward or away from the roller frame to compress or release the pressing spring.

[0013] Optionally, the pressing mechanism further includes a support, which is vertically adjustable on the support member. The pressure plate and roller frame are vertically slidably mounted on the support. The pushing member is an adjusting bolt. The support is provided with an adjusting screw hole. The adjusting bolt is screwed into the adjusting screw hole, and the end of the adjusting bolt abuts against the pressure plate.

[0014] In summary, this application includes at least the following beneficial technical effects: after the fabric is laid on the adhesive film, the fabric and adhesive film pass between the bottom end of the scraper and the upper surface of the support plate. When the fabric and adhesive film move, the bottom end of the scraper smooths out any uneven or wrinkled areas on the fabric. Then, the fabric and adhesive film pass between the fixed roller and the moving roller, and the fixed roller and the moving roller roll and compact the fabric and adhesive film after they have been smoothed by the scraper. This not only achieves a better smoothing effect on the fabric and adhesive film, but also a better compaction effect, thereby effectively improving the composite effect of the fabric and adhesive film and reducing the frequency of defects after the fabric and adhesive film are composited.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0018] This application discloses a compaction device for adhesive fiber fabrics used in composite materials.

[0019] A compaction device for composite material film fiber fabric includes a support member 90, a leveling mechanism, and a pressing mechanism.

[0020] Reference Figures 1 to 4 The leveling mechanism includes a scraper 10, a support plate 100, a bracket 20, a height adjustment component 30, and a fixing component, all mounted on a support member 90. The scraper 10 is positioned above the support plate 100 and is used to level the upper surface of the fabric 110. The bottom end of the scraper 10 is rounded to avoid damaging the fabric 110. The support plate 100 is used to support the fabric 110 and the adhesive film 120 passing under the scraper 10.

[0021] In an optional embodiment, the specific structure of the support member 90, and the specific connection relationship between the scraper 10 and the support plate 100 and the support member 90 are as follows: the bracket 20 is vertically adjustable on the support member 90, and the scraper 10 and the height adjustment component 30 are disposed on the bracket 20.

[0022] More specifically, the support 90 includes a frame 91, a base 92, fasteners, a support spring 922, and an adjusting nut 923. The support plate 100 is fixed on the frame 91. The fasteners include a fastening plate 93 and a fastening nut 94. The frame 91 is provided with a frame groove 911. The base 92 is placed on the upper surface of the frame 91. The fastening plate 93 is located in the frame groove 911. The fastening plate 93 is provided with an upwardly extending fastening stud 931. The fastening stud 931 passes through the base 92. The fastening nut 94 is screwed to the fastening stud 931 to fix the base 92 on the frame 91.

[0023] A first vertical screw 921 is provided on the base 92. The bracket 20 is sleeved on the first vertical screw 921. A support spring 922 is sleeved on the outside of the first vertical screw 921 and supported below the bracket 20. An adjusting nut 923 is screwed to the first vertical screw 921 and abuts against the upper part of the bracket 20. By rotating the adjusting nut 923, the position of the adjusting nut 923 on the first vertical screw 921 can be adjusted. At the same time, the support spring 922 will be compressed or extended accordingly, thereby adjusting the height of the bracket 20, and thus adjusting the distance between the bottom end of the scraper 10 and the support plate 100 to adapt to the need for smoothing fabrics 110 and adhesive films 120 of different thicknesses.

[0024] Reference Figures 3 to 6 The scraper 10 has multiple blades, each with a different hardness. By using multiple scrapers 10 with varying hardness, it can adapt to the smoothing needs of different fabric materials 110. For example, when smoothing soft and delicate fabrics 110 such as silk and tulle, a scraper 10 made of materials with lower hardness, such as rubber or silicone, can be used to avoid scratching the surface of the fabric 110, causing fiber breakage, scratches, etc., thus minimizing damage to the fabric 110. When smoothing harder and thicker fabrics 110 such as denim and canvas, a scraper 10 made of materials with higher hardness, such as metal or hard plastic, can be used to smooth out wrinkles and uneven areas on the fabric surface due to its rigidity.

[0025] The height adjustment component 30 is used to adjust the height of the multiple scraper blades 10 individually. When it is necessary to use one of the scraper blades 10 to level the upper surface of the fabric 110, the height of that scraper blade 10 can be adjusted by the height adjustment component 30 so that its height is lower than the other scraper blades 10. In an optional embodiment, the height adjustment component 30 may have the following structure: The height adjustment assembly 30 includes a lifting drive and a vertical shift seat 31. The vertical shift seat 31 is slidably mounted on the bracket 20. The lifting drive is mounted on the bracket 20 and connected to the vertical shift seat 31. The multi-blade scraper 10 is detachably connected to the vertical shift seat 31 via a connector.

[0026] More specifically, the specific structure of the lifting drive component and its specific connection relationship with the vertical shift seat 31 are as follows: The lifting drive component includes a lifting screw 32, a vertical frame 21 is provided on the bracket 20, the vertical shift seat 31 is slidably provided on the vertical frame 21, the vertical frame 21 is provided with a lifting screw hole 211, the lifting screw 32 is screwed to the lifting screw hole 211, and is rotatably connected to the vertical shift seat 31.

[0027] More specifically, the specific structure of the connector and its specific connection relationship with the vertical shift seat 31 and the scraper 10 are as follows: the connector is a connecting bolt 33, the scraper 10 is provided with a slide seat 11, the scraper 10 is slidably mounted on the bracket 20 through the slide seat 11, the slide seat 11 is provided with a protrusion 111, the protrusion 111 is provided with a connecting hole 112, the vertical shift seat 31 is provided with a connecting screw hole 312, the connecting bolt 33 is screwed into the connecting screw hole 312 and can be inserted into the connecting hole 112.

[0028] The fixing component is used to fix the scraper 10 to the bracket 20 after the scraper 10 is separated from the vertical moving seat 31. More specifically, the specific structure of the fixing component and its specific connection relationship with the scraper 10 and the bracket 20 are as follows: the fixing component is a magnet block 113. The bracket 20 is provided with a vertical groove 22. The slide 11 is inserted into the vertical groove 22. The magnet block 113 is fixed on the top of the slide 11. The magnet block 113 can be attracted and connected to the top wall of the vertical groove 22 of the bracket 20.

[0029] Reference Figures 1 to 4 The pressing mechanism includes a fixed roller 40, a movable roller 50, an elastic element, and a pressure adjusting assembly 60, all mounted on a support member 90. The fixed roller 40 is rotatably mounted on the frame 91. The elastic element acts on the movable roller 50 and provides a spring force to push the movable roller 50 toward the fixed roller 40. The fabric 110 and the adhesive film 120, after being flattened by the scraper 10, pass between the fixed roller 40 and the movable roller 50. The fixed roller 40 and the movable roller 50 are used to roll the fabric 110 and the adhesive film 120 after being flattened by the scraper 10. The elastic element provides a pressing force on the fabric 110 and the adhesive film 120 during rolling.

[0030] The elastic element can be a compression spring 61. The pressure adjustment component 60 is provided on the support 90. The pressure adjustment component 60 can act on the compression spring 61 and is used to adjust the extension and contraction of the compression spring 61, thereby adjusting the clamping force of the moving roller 50 on the fabric 110 and the adhesive film 120 to meet the clamping needs of fabrics 110 and adhesive films 120 of different materials.

[0031] In an optional embodiment, the pressure regulating assembly 60 may have the following structure: the pressure regulating assembly 60 includes a pushing member and a pressure plate 62, and the pressing mechanism further includes a roller frame 70. The pressure plate 62 and the roller frame 70 are slidably mounted on the support member 90 along the vertical direction. The movable roller 50 is rotatably mounted on the roller frame 70. The pressing spring 61 is disposed between the pressure plate 62 and the roller frame 70. The pushing member is disposed on the support member 90 and is used to push the pressure plate 62 to move toward or away from the roller frame 70 to compress or release the pressing spring 61, thereby adjusting the extension and contraction of the pressing spring 61.

[0032] The specific structure of the pushing component and its specific connection with the pressure plate 62 are as follows: the pushing component is an adjusting bolt 63, and the pressing mechanism also includes a support 80. The support 80 is vertically adjustable on the support 90. More specifically, the base 92 is provided with a second vertical screw 924, the support 80 is sleeved on the second vertical screw 924, and is fixed to the second vertical screw 924 by a locking nut 925.

[0033] The support 80 is equipped with a guide post 82. The compression spring 61, pressure plate 62, and roller frame 70 are vertically slidably mounted on the guide post 82 of the support 80. By adjusting the position of the locking nut 925 on the second vertical screw 924, the height of the support 80 can be adjusted, thereby adjusting the distance between the moving roller 50 and the fixed roller 40 to accommodate the pressing needs of fabrics 110 and adhesive films 120 of different thicknesses. The support 80 is equipped with an adjusting screw hole 81, and an adjusting bolt 63 is screwed into the adjusting screw hole 81. The end of the adjusting bolt 63 abuts against the pressure plate 62. When the adjusting bolt 63 is rotated, it can be driven to move axially, thereby adjusting the height of the pressure plate 62, adjusting the compression amount of the compression spring 61 and the elastic force of the compression spring 61 acting on the roller frame 70, and thus adjusting the pressing force of the moving roller 50 on the fabric 110 and adhesive film 120.

[0034] The implementation principle of the composite material film fiber fabric compaction device in this embodiment is as follows: After the fabric 110 is laid on the film 120, the fabric 110 and the film 120 are passed between the bottom end of the scraper 10 and the upper surface of the support plate 100. Then, a matching scraper 10 is selected according to the material of the fabric 110, and the connecting bolt 33 is rotated to insert the connecting bolt 33 into the connecting hole 112 on the corresponding slide 11. Then, the lifting screw 32 is rotated, which drives the vertical moving seat 31 to move down, and then the connecting bolt 33 drives the slide 11 and the scraper 10 to move down, so that the bottom end of the scraper 10 contacts the upper surface of the fabric 110. Then, the adjusting bolt 63 is rotated to adjust the clamping force of the moving roller 50 on the fabric 110 and the film 120.

[0035] When the fabric 110 and the film 120 move, the bottom end of the scraper 10 scrapes the uneven or wrinkled parts of the fabric 110, and then the fabric 110 and the film 120 pass between the fixed roller 40 and the moving roller 50. The fixed roller 40 and the moving roller 50 roll and compact the fabric 110 and the film 120 after they have been scraped flat by the scraper 10.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
