Composite fiber material for decorative material and production system

Abstract

This invention discloses a composite fiber material for decorative materials and its preparation system, including a composite gasket. The composite gasket comprises a porous fiber layer and a medium-polymer fiber layer disposed in the middle section of the porous fiber layer. The two porous fiber layers are bonded to a wall and an exterior paint layer. The medium-polymer fiber layer is an elastic layer. Specifically relating to the technical field of composite fiber materials for decorative materials and their preparation system, after applying a wall primer, the composite gasket is bonded to the primer. This allows the porous fiber layer to adhere to the primer through the porous fibers, assisting the primer in forming the wall surface. Simultaneously, the porous fibers absorb the excess primer, and the porous structure diffuses the primer, aiding in drying and solidification, preventing the primer from becoming too thick. The medium-polymer fiber layer, being an elastic layer, can be bent to fit curved surfaces.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0037] Example 1

[0038] like Figure 2 As shown, a composite fiber material for decorative materials includes a composite gasket 1. The composite gasket 1 includes a porous fiber layer 12 and a medium-polymer fiber layer 11 disposed in the middle section of the porous fiber layer 12. The two porous fiber layers 12 are bonded to the wall and the exterior paint layer. The medium-polymer fiber layer 11 is an elastic layer.

[0039] Specifically, the pores in the medium-density fiber layer 11 are smaller than those in the porous fiber layer 12, so as to reduce the amount of primer entering the medium-density fiber layer 11 along the porous fiber layer 12. This allows the primer to diffuse along the porous fiber layer 12 in areas where the primer is thicker, rather than spreading continuously along the medium-density fiber layer 11. The medium-density fiber layer 11 is an elastic layer, giving the overall composite gasket 1 a certain degree of toughness and resilience, making it easy to keep the composite gasket 1 flat and not easily bent during construction and normal storage.

[0040] Furthermore, both the porous fiber layer 12 and the medium-polymer fiber layer 11 are made of whole clumps of fibers and formed into a single composite gasket 1 through a felting process.

[0041] In the above technical solution, after applying the wall primer, the composite gasket 1 is attached to the primer so that the porous fiber layer 12 is adsorbed onto the primer through the porous fibers to assist the primer in the formation of the wall surface. At the same time, the porous fibers absorb the primer and diffuse it through the porous structure to assist in air drying and solidification, thus avoiding the primer from being too thick. The medium-density fiber layer 11 is an elastic layer that can be bent and fit the curved surface.

[0042] As an embodiment of the present invention, the composite gasket 1 comprises the following raw materials in parts by weight: 18-20 parts of plant fiber and 5-13 parts of polypropylene coarse fiber;

[0043] The medium-weight fiber layer 11 comprises the following raw materials in parts by weight: 5-10 parts of acrylic resin, 3-5 parts of calcium carbonate, 1-3 parts of stabilizer, and 5-10 parts of nitrile rubber.

[0044] Specifically, the composite gasket 1 comprises the following raw materials in parts by weight: 18-20 parts of plant fiber and 5-13 parts of polypropylene coarse fiber;

[0045] The medium rubber fiber layer 11 is filled with a toughening composite agent. The toughening composite agent is filled in the middle layer of the composite gasket 1 and solidifies to reduce the voids in the medium rubber fiber layer 11. The toughening composite agent includes the following raw materials in parts by weight: 5-10 parts of acrylic resin, 3-5 parts of calcium carbonate, 1-3 parts of stabilizer, and 5-10 parts of nitrile rubber.

[0046] Furthermore, the connection between the medium-density fiber layer 11 and the porous fiber layer 12 can be achieved by bonding with an adhesive, or by filling the middle layer of the entire porous fiber layer 12 with a toughening composite agent to form the medium-density fiber layer 11, or by other structures known to those skilled in the art.

[0047] Example 2

[0048] like Figure 1-11 As shown, a preparation system includes:

[0049] The conveyor base 3 includes a conveyor belt 31;

[0050] The intermediate immersion mechanism 2 includes a pressure roller 21 and an injection tube 22. Multiple injection needles 221 are arranged in a linear array on the injection tube 22. They are driven to the pressure roller 21 by the conveyor belt 31 of the composite gasket 1. The pressure roller 21 is driven to rotate and insert the injection needles 221 into the composite gasket 1 to inject glue and form the intermediate glue fiber layer 11.

[0051] Specifically, the pressure roller 21 has a through hole 213 for the glue injection bend 221 to pass through. A rotating drum is rotatably connected to the conveyor base 3. The conveyor belt 31 is mounted on the rotating drum and rotates to transport the composite gasket 1. The pressure roller 21 is rotatably connected to the conveyor base 3. The rotation direction of the pressure roller 21 is the same as the rotation direction of the conveyor belt 31 to press the composite gasket 1. The glue injection tube 22 is set inside the pressure roller 21 and can rotate with the pressure roller 21. When rotating, the glue injection bend 221 will be inserted into the already pressed composite gasket 1 to inject glue, so as to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12, thus completing the production.

[0052] In the above technical solution, the glue injection mode of the glue injection bend 221 insertion is faster than the multi-layer bonding method. It does not require adhesive bonding, which reduces costs and improves the integrity of the gasket. It is less likely to delaminate due to the passage of time or adhesive failure, making it more durable. In addition, the rotation stroke of the glue injection bend 221 is fixed, which makes the glue injection position fixed, thereby fixing the position of the middle glue fiber layer 11 and reducing product error.

[0053] As one embodiment of the present invention, a pressing flap 23 is rotatably connected to the pressing roller 21. The pressing flap 23 rotates with the pressing roller 21 to adhere to the composite gasket 1 and stop, and the glue injection needle 221 penetrates and inserts into the composite gasket 1 along the pressing flap 23.

[0054] Specifically, the pressure roller 21 has a travel groove 211, and a limiting protrusion 212 is provided on the travel groove 211. The pressing flap 23 is flipped and connected to the travel groove 211. When not restricted by external force, the pressing flap 23 flips out of the travel groove 211 and blocks the glue injection bend 221, which is the initial position. When fixing the composite gasket 1, the pressure roller 21 rotates and the pressing flap 23 first comes into contact with the composite gasket 1. As the pressure roller 21 continues to rotate, the pressing flap 23 stops, and the travel groove 211 approaches the pressing flap 23 to extend the glue injection bend 221 from the pressing flap 23 and insert it into the composite gasket 1 for glue injection. The fixed pressing flap 23 pre-presses and fixes the composite gasket 1, which has better stability than fixing it with the continuously rolling pressure roller 21 and is less likely to cause the composite gasket 1 to shift. At the same time, the pressing flap 23 allows the glue injection bend 221 to extend or retract, which plays a protective role.

[0055] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31. As the pressure roller 21 rotates, it first comes into contact with the composite gasket 1 by the pressing flip plate 23 and then stops. As it continues to rotate, the glue injection needle 221 extends out from the pressing flip plate 23 to insert into the composite gasket 1 for glue injection, so as to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0056] As one embodiment of the present invention, the pressing flip plate 23 includes the following two stations:

[0057] First station: Pressing flip plate 23 rotates with pressing roller 21 to adhere to composite gasket 1 and then stops;

[0058] Second station: The pressing flip plate 23 is driven to flip in the opposite direction to the pressing roller 21, and the glue injection bending needle 221 is pulled back and pressed against the composite gasket 1.

[0059] Specifically, the pressure roller 21 has two stations when pressing the composite gasket 1. The two stations switch as the pressure roller 21 rotates. When the pressure roller 21 initially presses the composite gasket 1, the pressing flap 23 is in the first station, that is, the pressure roller 21 rotates and the pressing flap 23 first adheres to the composite gasket 1 and stops. At this time, the composite gasket 1 is pressed and fixed, which facilitates the insertion of the glue injection needle 221 into the composite gasket 1 driven by the rotation. As the pressure roller 21 continues to rotate, after the glue injection by the glue injection needle 221 is completed, the pressing flap 23 will switch to the first station. The second station is where the pressing flap 23 is driven to flip in the opposite direction to the pressing roller 21, so that the pressing flap 23 is disengaged from the stroke groove 211. At the same time, while pressing the composite gasket 1, the injection bend 221 inserted into the composite gasket 1 is blocked again, that is, the injection bend 221 is removed from the composite gasket 1. Simultaneously, when the pressing flap 23 flips in the opposite direction to the pressing roller 21, it presses against the composite gasket 1 to compress it, so that the injected glue is pressed and diffused. After being pressed and diffused, it rebounds to form the medium glue fiber layer 11, realizing the structure that the pores of the medium glue fiber layer 11 are smaller than those of the pore fiber layer 12.

[0060] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31, causing the pressure roller 21 to switch from its initial position to the first working position: as the pressure roller 21 rotates, the pressure flip plate 23 first adheres to the composite gasket 1 and stops, and then as it continues to rotate, the glue injection needle 221 extends out from the pressure flip plate 23 to insert into the composite gasket 1 for glue injection. Subsequently, the pressure flip plate 23 will switch to the second working position, that is, the pressure flip plate 23 is driven to flip in the opposite direction to the pressure roller 21, so that the pressure flip plate 23 is disengaged from the stroke groove 211, so as to press the composite gasket 1 and at the same time cover the glue injection needle 221 inserted into the composite gasket 1 again. At the same time, when the pressure flip plate 23 flips in the opposite direction to the pressure roller 21, it will press against the composite gasket 1 to compress it, so as to press and spread the injected glue to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0061] As an embodiment of the present invention, the pressing flap 23 is movably provided with an inclined slider 27 for sealing the glue injection bend 221. The glue injection bend 221 has an inclined surface 2211, which pushes the inclined slider 27 to move.

[0062] Specifically, the pressing flap 23 has a blocking groove, and the inclined slider 27 is slidably connected to the blocking groove. An elastic element 271 is provided between the two. When the pressing flap 23 is in the initial state or the second working position, the pressing flap 23 will block the glue injection bend 221, so that the elastic element 271 pushes the inclined slider 27 to block the glue outlet of the glue injection bend 221 and seal it. When the pressing flap 23 is in the first working position, the inclined surface 2211 will push the inclined slider 27 to slide along the blocking groove and lose the function of blocking the glue outlet of the glue injection bend 221, so that the glue injection bend 221 can dispense glue normally.

[0063] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31, causing the pressure roller 21 to switch from its initial position to the first working position: as the pressure roller 21 rotates, it is first pressed against the composite gasket 1 by the pressing flap 23 and then stops. As it continues to rotate, the glue injection needle 221 extends out from the pressing flap 23. At the same time, the inclined surface 2211 pushes against the inclined slider 27 and slides along the shielding groove to open the glue injection needle 221, so that the glue injection needle 221 can be inserted into the composite gasket 1 for glue injection. Afterwards, the pressing flap 23 will switch to the second working position, which is the pressing flap. The pressure roller 23 is reversed from the pressure roller 21, so that the pressure plate 23 is disengaged from the stroke groove 211. While pressing the composite gasket 1, the injection needle 221 inserted into the composite gasket 1 is blocked again. The elastic element 271 pushes against the inclined slider 27 to block the outlet of the injection needle 221 and seal it. At the same time, when the pressure plate 23 is reversed from the pressure roller 21, it will press against the composite gasket 1 to compress it, so as to press and spread the injected glue to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0064] As one embodiment of the present invention, it also includes a fixing ring 25, on which a coupling tooth 251 is provided, and a connecting shaft 24 intermittently coupled to the coupling tooth 251 is rotatably connected to the pressure roller 21, and the connecting shaft 24 couples the pressing flip plate 23.

[0065] Specifically, coupling teeth 251 are disposed on the outer ring of fixed ring 25. Fixed base 26 is disposed on conveying base 3. Elastic connecting strips 261 are arranged in a circumferential array on fixed base 26. The inner wall of fixed ring 25 is connected and fixed to elastic connecting strips 261. A connecting shaft 24 intermittently coupled to coupling teeth 251 is rotatably connected to pressure roller 21. Coupling part 241 is disposed on connecting shaft 24. Coupling part 241 is coupled to coupling teeth 251. Connecting shaft 24 couples to pressing flap 23. Rotating shaft 231 is disposed on pressing flap 23. Rotating shaft 231 and connecting... The rotating shaft 24 is coupled. When the pressing flip plate 23 is in the first working position, the coupling part 241 is in contact with the coupling tooth 251. When the pressing flip plate 23 is switched to the second working position, the coupling part 241 rotates with the pressing roller 21 along the outer ring of the fixed ring 25 and is coupled with the coupling tooth 251, thereby driving the rotating shaft 231 to achieve a reverse flip. After the reverse flip force exceeds the deformation force of the elastic connecting strip 261, the deformation of the elastic connecting strip 261 drives the fixed ring 25 to flip along the fixed base 26, so as to keep the pressing flip plate 23 blocking the glue injection bent needle 221 while pressing the composite gasket 1.

[0066] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31, causing the pressure roller 21 to switch from its initial position to the first working position: as the pressure roller 21 rotates, it first comes into contact with the composite gasket 1 by the pressing flap 23 and stops, then continues to rotate, extending the glue injection needle 221 from inside the pressing flap 23. At the same time, the inclined surface 2211 pushes against the inclined slider 27, which slides along the shielding groove to open the glue injection needle 221, allowing it to be inserted into the composite gasket 1 for glue injection. Subsequently, the coupling part 241 rotates along the outer ring of the fixing ring 25 with the pressure roller 21 and couples with the coupling teeth 251, thereby driving the rotating shaft 231 to achieve phase coupling. Reverse rotation switches the pressing flip plate 23 to the second station, where the pressing flip plate 23 is driven to rotate in the opposite direction to the pressing roller 21, so that the pressing flip plate 23 is disengaged from the stroke groove 211. At the same time, while pressing the composite gasket 1, the injection needle 221 inserted into the composite gasket 1 is blocked again. The elastic element 271 pushes against the inclined slider 27 to block the glue outlet of the injection needle 221 and seal it. At the same time, when the pressing flip plate 23 rotates in the opposite direction to the pressing roller 21, it will press against the composite gasket 1 to compress it, so as to press and spread the injected glue to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0067] As one embodiment of the present invention, the pressing flap 23 is provided with a movable groove 232, which is driven to fit the glue injection bend 221 to restrict the glue injection bend 221 or the pressing flap 23.

[0068] Specifically, the movable groove 232 is used to accommodate the glue injection bend 221, so that the glue injection bend 221 can extend or retract to press the flip plate 23 as the pressure roller 21 rotates. The movable groove 232 includes an upper bonding surface and a lower bonding surface (to... Figure 10For reference (the upper bonding surface is the upper end, and the lower bonding surface is the lower end), when the glue injection bend 221 retracts to press the flip plate 23, the glue injection bend 221 will adhere to the upper bonding surface. At the same time, the upper bonding surface will restrict the pressing flip plate 23 so that the travel limit of the pressing flip plate 23 to reverse is the upper bonding surface. When the glue injection bend 221 extends along the movable groove 232, since the pressing flip plate 23 stops moving, the glue injection bend 221 will adhere to the lower bonding surface to limit the extension distance of the glue injection bend 221, thereby controlling the glue injection depth and preventing the glue injection bend 221 from extending too far and being damaged.

[0069] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31, causing the pressure roller 21 to switch from its initial position to the first working position: as the pressure roller 21 rotates, the pressure plate 23 first adheres to the composite gasket 1 and stops, and then as it continues to rotate, the injection needle 221 extends out from the pressure plate 23, causing the injection needle 221 to adhere to the lower bonding surface for restriction. At the same time, the inclined surface 2211 pushes against the inclined slider 27 and slides along the shielding groove to open the injection needle 221, allowing the injection needle 221 to be inserted into the composite gasket 1 for injection. Subsequently, the coupling part 241 rotates along the outer ring of the fixing ring 25 with the pressure roller 21 and couples with the coupling teeth 251, thereby driving the rotating shaft 231 to achieve... The pressing plate 23 is switched to the second station by reversing the pressure plate 23 and the pressure roller 21. This causes the pressing plate 23 to disengage from the stroke groove 211 and press the composite gasket 1. At the same time, the injection needle 221 inserted into the composite gasket 1 is retracted, so that the injection needle 221 will adhere to the bonding surface and block again. The elastic element 271 pushes the inclined slider 27 to block the glue outlet of the injection needle 221 and seal it. At the same time, when the pressing plate 23 reverses the pressure roller 21, it will press against the composite gasket 1 to compress it, so as to press and diffuse the injected glue to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0070] As the preferred embodiment provided by the present invention, a motor 32 for driving the conveyor belt 31 is provided on the conveyor base 3, and a transmission belt 33 is sleeved between the output end of the motor 32 and the pressure roller 21.

[0071] A glue-feeding tube 220 is rotatably connected to the glue-feeding tube 22, and the glue-feeding tube 220 is fixedly connected to the glue-feeding unit.

[0072] Specifically, a motor 32 for driving the conveyor belt 31 is provided on the conveyor base 3. A rotating seat 34 is rotatably connected to the conveyor base 3. A transmission belt 33 is sleeved between the rotating seat 34 and the output end of the motor 32. The motor 32 drives the transmission belt 33 to drive the rotating seat 34 to rotate, thereby driving the pressure roller 21 to rotate. The pressure roller 21 and the transmission belt 33 rotate in the same direction. A glue pipe 220 is rotatably connected to the glue injection pipe 22. The glue pipe 220 is fixedly connected to the glue injection unit, which is a glue pump. The glue pump drives the glue to continuously supply glue to the glue pipe 220.

[0073] The composite gasket 1 moves toward the pressure roller 21 along the conveyor belt 31, causing the pressure roller 21 to switch from its initial position to the first working position: as the pressure roller 21 rotates, the pressure plate 23 first adheres to the composite gasket 1 and stops, and then as it continues to rotate, the injection needle 221 extends out from the pressure plate 23, causing the injection needle 221 to adhere to the lower bonding surface for restriction. At the same time, the inclined surface 2211 pushes against the inclined slider 27 and slides along the shielding groove to open the injection needle 221, allowing the injection needle 221 to be inserted into the composite gasket 1 for injection. Subsequently, the coupling part 241 rotates along the outer ring of the fixing ring 25 with the pressure roller 21 and couples with the coupling teeth 251, thereby driving the rotating shaft 231 to achieve... The pressing plate 23 is switched to the second station by reversing the pressure plate 23 and the pressure roller 21. This causes the pressing plate 23 to disengage from the stroke groove 211 and press the composite gasket 1. At the same time, the injection needle 221 inserted into the composite gasket 1 is retracted, so that the injection needle 221 will adhere to the bonding surface and block again. The elastic element 271 pushes the inclined slider 27 to block the glue outlet of the injection needle 221 and seal it. At the same time, when the pressing plate 23 reverses the pressure roller 21, it will press against the composite gasket 1 to compress it, so as to press and diffuse the injected glue to form a medium glue fiber layer 11 in the middle of the porous fiber layer 12.

[0074] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
