Description

Technical Field

[0001] This invention relates to the field of carbon fiber fabrics, and more specifically to a structure for preventing activated carbon fiber composite fabrics from loosening. Background Technology

[0002] Carbon fiber cloth, also known as carbon fiber cloth, carbon fiber woven cloth, carbon fiber reinforcement cloth, etc., is a unidirectional carbon fiber reinforcement product, usually woven from 12K carbon fiber filaments. Carbon fiber cloth is used for tensile, shear, and seismic reinforcement of structural components. This material, together with matching impregnating adhesive, becomes a carbon fiber composite material, which can form a complete and high-performance carbon fiber sheet reinforcement system. It is suitable for reinforcement projects that address increased building loads, changes in engineering functions, material aging, concrete strength grades below design values, structural crack treatment, repair and protection of components serving in harsh environments. It also has a wide range of applications and is widely used for reinforcement, repair, seismic reinforcement, and structural reinforcement of joints in various structural types and shapes such as buildings, bridges, and tunnels.

[0003] A current Chinese patent publication number, CN115401958A, discloses an activated carbon fiber composite fabric and its preparation process, comprising a fabric layer and an inner lining layer. The fabric layer comprises the following materials in parts by weight: 30-40 parts activated carbon fiber, 5-10 parts bamboo fiber, 10-15 parts polyester fiber, and 3-10 parts microfiber. The inner lining layer comprises the following materials in parts by weight: 30-40 parts cotton fiber, 10-15 parts hemp fiber, and 5-10 parts jade fiber. The preparation process includes: making the fabric layer: blending and weaving the fibers into fabric one according to the parts by weight; applying a protective liquid to both surfaces of fabric one using a surface treatment device, the coated fabric one being the fabric layer; making the inner lining layer: blending and weaving the fibers into fabric two according to the parts by weight, the woven fabric two being the inner lining layer; and bonding: bonding the fabric layer and the inner lining layer using a bonding machine to obtain the activated carbon fiber composite fabric. The activated carbon fiber composite fabric and its preparation process of this invention have high adhesion, fast production efficiency, and the woven fabric is lightweight, soft to the touch, breathable, and highly waterproof.

[0004] The carbon fiber fabrics mentioned above also have the following problems when used: carbon fiber fabrics on the market are all sold in rolls. When carbon fiber fabric is needed, a portion is usually pulled out and cut from a roll of fabric. However, some fabrics are not tightly bonded together during the winding process. This can easily cause the entire roll of fabric to loosen when the fabric is pulled out later, making it difficult to rewind the fabric later.

[0005] Therefore, it is necessary to invent a structure to prevent activated carbon fiber composite fabrics from loosening in order to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a structure for preventing activated carbon fiber composite fabrics from loosening, in order to solve the problem mentioned in the background art that the carbon fiber fabrics on the market are all sold in rolls. When carbon fiber fabric is needed, a portion is usually pulled and cut from a roll of fabric. However, some fabrics are not tightly bonded together during the winding process, which can easily cause the entire roll of fabric to loosen when the fabric is pulled out later, making it difficult to rewind the fabric.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a structure for preventing activated carbon fiber composite fabric from loosening, comprising a roller shaft, wherein a cavity is formed inside the roller shaft, and fabric is wound around the outer ring of the roller shaft, and further comprising:

[0008] The mounting assembly includes a chassis that is movably fitted inside the cavity, and two protrusions that are fixedly connected to both ends of the chassis, with the protrusions being movably connected to the slide groove.

[0009] The limiting part has a notch on the top of the chassis, and a fixing rod is fixedly connected to the inner wall of the notch. A lever is movably sleeved on the outer ring of the fixing rod, and a locking block is fixedly connected to the outer wall of the lever. The locking block and the locking slot can be matched.

[0010] The anti-loosening component has an externally fixed mounting frame for the lever plate, and the mounting frame has a movable cavity, in which a movable block is movably fitted.

[0011] The clamping part has a long rod fixedly connected to the bottom of the movable block, and a sleeve is movably sleeved on the outer ring of the long rod.

[0012] Preferably, the outer ring of the chassis is a smooth surface, and the outer ring of the chassis is in contact with the inner wall of the internal cavity of the roller shaft and is slidably connected up and down;

[0013] The chassis sidewall is fixedly connected to two symmetrical protrusions, and the protrusions are in contact with the inner walls of two open vertical sliding grooves preset inside the roller shaft and are slidably connected up and down. The protrusions are also in contact with the inner wall of the annular movable groove connected to the sliding grooves and are movably connected.

[0014] The bottom of the chassis is flush with the bottom of the entire roller shaft.

[0015] Preferably, the chassis has an open square notch inside, and two symmetrical fixing rods are fixedly connected to the inner wall of the square notch, and two symmetrical levers are rotatably connected to the outer ring of the two fixing rods through bearings.

[0016] The outer ring of the fixed rod is movably sleeved with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the side wall of the lever plate and the inner wall of the notch.

[0017] Both of the aforementioned levers have a locking block fixedly connected to one end wall of the inner wall of the columnar cavity inside the roller shaft. The locking block matches a pre-set locking groove inside the roller shaft, and the locking groove is annular and connected to a vertical sliding groove.

[0018] Preferably, there are two mounting frames, and the two mounting frames are fixed on two levers respectively. The mounting frames are arranged in the same direction as the locking blocks, and the bottom of the mounting frames is in contact with the top of the wound fabric.

[0019] The mounting frame has an internal movable cavity, and the bottom of the mounting frame also has a through-channel that communicates with the movable cavity. A light rod is fixedly connected inside the movable cavity, and a movable block is movably sleeved on the outer ring of the light rod. The outer wall of the movable block fits against and slides against the inner wall of the movable cavity.

[0020] A spring is fixedly connected to one end of the movable block, and the other end of the spring is fixedly connected to the inner wall of the movable cavity. At the same time, the spring is movably sleeved on the outer ring of the smooth rod.

[0021] Preferably, a columnar rod is fixedly connected to the bottom of the movable block. The rod passes through a vertically penetrating groove at the bottom of the mounting frame, and a sleeve is rotatably fitted around the outer ring of the rod, with the outer ring of the sleeve in contact with the fabric surface.

[0022] The sleeve has a columnar open mounting groove inside. The inner wall of the mounting groove fits and is rotatably connected to the outer wall of the long rod. Two symmetrical protrusions are fixedly connected to the inner wall of the top opening of the mounting groove. The protrusions are slidably connected to an annular groove preset inside the long rod.

[0023] This invention also provides a process for preparing activated carbon fiber composite fabric, comprising the following steps:

[0024] Step 1: Pretreatment oxidation. The plastic fibers are placed in a high-temperature oxidation furnace at 250°C to absorb oxygen molecules, rearrange the atomic structure of the fibers, and enhance thermal stability. The oxidation time is 1-1.5 hours.

[0025] Step 2: Carbonization treatment. The oxidized fiber filaments are sent into a carbonization processor for high-temperature carbonization treatment to remove non-carbon atoms from the fiber and generate carbon fiber filaments. The resin-coated carbon fiber filaments are then wound and collected.

[0026] Step 3: Weaving. The carbon fiber filaments coated with resin in Step 2 are woven into carbon fiber cloth by machine.

[0027] Step 4: Packaging. The staff will wind the finished carbon fiber fabric around the outer ring of the roller shaft and pack it into boxes according to batch.

[0028] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0029] By moving the two levers in opposite directions and simultaneously moving the two sleeves apart, it is easy to install the mounting components and anti-loosening components in the roller shaft cavity. In this way, under the action of the spring, the sleeves are always in contact with the outer surface of the wound fabric, which secures the wound fabric and prevents the wound fabric from loosening and unfolding, thus affecting subsequent use.

[0030] At the same time, when the fabric is pulled, the pulling force will cause the fabric and the roller shaft fixed inside the fabric to rotate. The pre-set annular movable groove and annular locking groove inside the roller shaft are connected to the locking block and protrusion, so that the rotation of the roller shaft is not affected. At the same time, the pulling of the fabric during rotation makes it easier to take out the fabric. The two sets of sleeves clamp and limit the two sides of the whole roll of fabric to prevent the fabric from loosening after use. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] This invention provides, for example Figure 1-6 The structure shown is for preventing activated carbon fiber composite fabric from loosening, including a roller shaft 1, with a cavity 11 inside the roller shaft 1, and fabric 2 wound around the outer ring of the roller shaft 1, and further including:

[0042] The mounting component 3 is fitted with a base 31 inside the cavity 11, and the two ends of the base 31 are fixedly connected with protrusions 32, and the protrusions 32 are movably connected to the slide groove 33.

[0043] The limiting part 34 has a notch 341 on the top of the chassis 31, and a fixing rod 342 is fixedly connected to the inner wall of the notch 341. A lever 343 is movably sleeved on the outer ring of the fixing rod 342. A locking block 344 is fixedly connected to the outer wall of the lever 343, and the locking block 344 can match the locking groove 345.

[0044] The anti-loosening component 4 and the external fixed connection of the lever plate 343 are to the mounting frame 41, and the mounting frame 41 has a movable cavity 42, and the movable block 44 is movably sleeved in the movable cavity 42.

[0045] The clamping part 46 and the bottom of the movable block 44 are fixedly connected to a long rod 461, and the outer ring of the long rod 461 is movably sleeved with a sleeve 462.

[0046] The outer ring of the chassis 31 is a smooth surface, and the outer ring of the chassis 31 is in contact with the inner wall of the internal cavity 11 of the roller shaft 1 and is slidably connected up and down, so that the chassis 31 can move to drive the dial plate 343 to move, thereby facilitating the sleeve 462 to clamp the fabric 2 on the outer ring of the roller shaft 1 to prevent it from loosening and affecting the subsequent use of the fabric 2.

[0047] Two symmetrical protrusions 32 are fixedly connected to the side wall of the chassis 31. The protrusions 32 are in contact with the inner walls of the two open vertical sliding grooves 33 pre-set inside the roller shaft 1 and are slidably connected up and down. The protrusions 32 are in contact with the inner wall of the annular movable groove 331 connected to the sliding grooves 33 and are movably connected.

[0048] The bottom of the chassis 31 is flush with the bottom of the entire roller shaft 1.

[0049] The chassis 31 has an open square notch 341 inside, and two symmetrical fixing rods 342 are fixedly connected to the inner wall of the square notch 341. The outer rings of the two fixing rods 342 are rotatably connected to two symmetrical lever plates 343 through bearings, which facilitates the installation of the entire mounting assembly 3 and the anti-loosening assembly 4 by moving the lever plates 343.

[0050] A torsion spring is movably sleeved on the outer ring of the fixed rod 342, and the two ends of the torsion spring are fixedly connected to the side wall of the lever 343 and the inner wall of the notch 341, respectively, so that the lever 343 can automatically reset after being moved.

[0051] Two lever plates 343 are fixedly connected to one end wall of the inner wall of the columnar cavity 11 inside the roller shaft 1. The locking block 344 matches the preset locking groove 345 inside the roller shaft 1. The locking groove 345 is annular and is connected to the vertical sliding groove 33 to facilitate the limiting of the entire installation component 3 after installation, and to prevent the installation component 3 from moving up and down.

[0052] There are two mounting frames 41, and the two mounting frames 41 are fixed on two lever plates 343 respectively. The mounting frames 41 and the locking blocks 344 are arranged in the same direction, and the bottom of the mounting frames 41 is in contact with the top of the wound fabric 2.

[0053] The mounting frame 41 has an internal movable cavity 42. The bottom of the mounting frame 41 also has a vertically connected channel that is connected to the movable cavity 42. A light rod 43 is fixedly connected inside the movable cavity 42. A movable block 44 is movably sleeved on the outer ring of the light rod 43. The outer wall of the movable block 44 fits against the inner wall of the movable cavity 42 and is slidably connected.

[0054] A spring 45 is fixedly connected to one end of the movable block 44, and the other end of the spring 45 is fixedly connected to the inner wall of the movable cavity 42. At the same time, the spring 45 is movably sleeved on the outer ring of the smooth rod 43.

[0055] The bottom of the movable block 44 is fixedly connected to a columnar rod 461. The rod 461 passes through the vertical through-slot opened at the bottom of the mounting frame 41. The outer ring of the rod 461 is rotatably fitted with a sleeve 462. The outer ring of the sleeve 462 contacts the surface of the fabric 2. The sleeve 462 fastens the surface of the fabric 2 to prevent the fabric 2 from becoming loose.

[0056] The sleeve 462 has a columnar open mounting groove 463 inside. The inner wall of the mounting groove 463 fits and is rotatably connected to the outer wall of the long rod 461. Two symmetrical protrusions 464 are fixedly connected to the inner wall of the top opening of the mounting groove 463. The protrusions 464 are slidably connected to an annular groove 465 pre-set inside the long rod 461. The thickness of the fabric 2 supports the entire sleeve 462 and the long rod 461, thereby driving the movable block 44 to generate tension on the spring 45 and deform it. After using the fabric 2, the thickness of the fabric 2 winding is reduced. Under the action of the spring 45, the movable block 44 moves, so that the sleeve 462 still fits tightly against the surface of the fabric 2, preventing the fabric 2 from loosening.

[0057] This invention also provides a process for preparing activated carbon fiber composite fabric, comprising the following steps:

[0058] Step 1: Pretreatment oxidation. The plastic fibers are placed in a high-temperature oxidation furnace at 250°C to absorb oxygen molecules, rearrange the atomic structure of the fibers, and enhance thermal stability. The oxidation time is 1-1.5 hours.

[0059] Step 2: Carbonization treatment. The oxidized fiber filaments are sent into a carbonization processor for high-temperature carbonization treatment to remove non-carbon atoms from the fiber and generate carbon fiber filaments. The resin-coated carbon fiber filaments are then wound and collected.

[0060] Step 3: Weaving. The carbon fiber filaments coated with resin in Step 2 are woven into carbon fiber cloth by machine.

[0061] Step 4: Packaging. The staff will wind the finished carbon fiber fabric 2 around the outer ring of the roller shaft 1 and pack it into boxes according to batch.

[0062] Working principle: First, when it is necessary to install the entire installation component 3, follow... Figure 2The two levers 343 are moved in opposite directions according to the arrow above the middle lever 343. Then, the sleeve 462 is moved in the direction indicated by the arrow next to the sleeve 462. The sleeve 462 is rotatably connected to the long rod 461, and the top of the long rod 461 is fixedly connected to the bottom of the movable block 44. Moving the sleeve 462 will drive the movable block 44 to move on the outer ring of the smooth rod 43, thereby generating a pulling force on the spring 45 fixedly connected to the movable block 44, causing it to deform. When the levers 343 are moved in opposite directions, the torsion spring movably sleeved on the outer ring of the fixed rod 342 is deformed by the force. Then, the protrusions 32 fixed on both ends of the base 31 are aligned with the groove opening of the slide groove 33. The base 31 is then moved downward so that the base 31 and the levers 343 are inserted into the cavity 11 inside the roller shaft body 1. The two symmetrical protrusions 32 fixed on the outer wall of the base 31 enter the vertical slide groove 33. Inside the connected annular movable groove 331, the lever 343 is released. At this time, the outer ring torsion spring of the fixed rod 342 loses its force and begins to reset, pushing the two levers 343 toward the inner wall of the cavity 11. This causes the locking block 344 fixed on the side wall of the lever 343 to match the annular locking groove 345. This causes the lever 343 and the chassis 31 to be restricted in the inner cavity 11 of the roller shaft 1, preventing the chassis 31 and the lever 343 from moving up and down. During the descent of the chassis 31 and the lever 343, the anti-loosening component 4 fixed to the outer wall of the lever 343 is engaged with the outer ring of the whole roll of fabric 2. Under the action of the spring 45, the sleeve 462, which is movably engaged with the outer ring of the long rod 461 fixed to the movable block 44, is tightly attached to the outer surface of the roll of fabric 2. The two sets of sleeves 462 clamp and limit the two sides of the whole roll of fabric 2, preventing the fabric 2 from loosening after use due to loose winding.

[0063] During the use of fabric 2, the thickness of the entire roll of fabric 2 is reduced. At this time, under the force of the spring 45 returning to its original position, the sleeve 462 is always in contact with the outer surface of fabric 2, thus ensuring that fabric 2 will not loosen. At the same time, when pulling fabric 2, it will drive the roller shaft 1 fixed in the inner circle of fabric 2 to rotate. The pre-set annular movable groove 331 and annular locking groove 345 inside the roller shaft 1 are rotatably connected with the locking block 344 and the protrusion 32. Thus, the rotation of roller shaft 1 is not affected, and it is also more convenient to take out fabric 2 when pulling it during rotation.

[0064] 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.
