Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a fiber pen tip conveying device. Background Technology

[0002] The conventional manufacturing process of fiber pen tips mainly includes the following steps: First, multiple single coarse fibers (such as polyester fibers) are transported to a bundling machine via a conveying device to form cylindrical fiber strips of a specified diameter; then, the bundled fiber strips are immersed in the glue tank of a glue coating machine, allowing the surface and interior to absorb the glue (usually water-based acrylic resin, etc.); finally, the glue-impregnated fiber strips are sent to a drying device, where they are cured and shaped by hot air, and finally cut into finished pen tips.

[0003] Currently, in industrial production, rovings are typically unwound in package form. Because rovings are in a curled and taut state for extended periods during spinning, winding, and storage, adsorption easily occurs between the internal fibers. This causes many fibers to not be completely independent and loose, but rather to stick together into smaller fiber bundles. This affects the quality of the roving when it enters the bundling machine, thus reducing the overall quality of the final product. Utility Model Content

[0004] The main purpose of this invention is to provide a fiber pen tip conveying device to improve the quality of fiber roving entering the yarn bundling machine, thereby improving the overall quality of the final product.

[0005] To achieve the above objectives, this utility model proposes a fiber pen tip conveying device, including a storage rack, a guide machine for transporting coarse fiber sand, and a wire bundling machine. The guide machine is located on one side of the storage rack, and the wire bundling machine is located on one side of the guide machine. The storage rack is provided with a plurality of storage rollers for storing coarse fiber sand, and a beating mechanism for beating the coarse fiber sand is provided between the wire bundling machine and the guide machine.

[0006] In one possible implementation, a base plate is provided between the wire harness machine and the feeder, and a support frame is provided on the top of the base plate. The tapping mechanism includes a tapping rod, a first connecting rod fixedly connected to the bottom of the tapping rod, an elastic element, and a drive assembly that causes the tapping rod to intermittently compress the elastic element. One side of the elastic element abuts against the top of the support frame, and the other side of the elastic element abuts against the bottom of the first connecting rod.

[0007] In one possible implementation, an extension rod is fixedly connected to the bottom of the striking rod, and the extension rod is fixedly connected to the first connecting rod by bolts.

[0008] In one possible implementation, guide rods are fixedly connected to both sides of the bottom of the first connecting rod, and limit blocks are fixedly connected to both sides of the support frame, with each guide rod slidingly connected to the corresponding limit block.

[0009] In one possible implementation, the elastic element is sleeved on the outer surface of the guide rod, and one side of the elastic element abuts against the top of the limiting block.

[0010] In one possible implementation, the drive assembly includes a second connecting rod fixedly connected to the bottom of each guide rod, an L-shaped plate fixedly connected to the bottom of the second connecting rod and inclined, a servo motor, and a rotating plate. A motor base is fixedly connected to the side of the support frame. The servo motor is fixedly connected to the motor base. The output end of the servo motor is fixedly connected to the rotating plate. A rotating wheel is provided on the rotating plate. The rotating wheel is slidably connected to one side of the L-shaped plate.

[0011] In one possible implementation, the rotating wheel is rotatably connected to the rotating plate, and the rotating wheel is cylindrical in shape.

[0012] Working principle and beneficial effects:

[0013] This utility model's technical solution, through a set beating mechanism, can beat the fibers before they enter the bundling machine. The vibration and impact generated during the beating process can improve the fiber's fluffiness and dispersion, thereby enhancing the uniformity and tightness of the bundling in the bundling machine, and improving the quality of the fiber roving when it enters the bundling machine, ultimately ensuring the quality stability and consistency of the fiber pen tip product.

[0021] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0023] refer to Figure 1-5 This embodiment proposes a fiber pen tip conveying device, mainly including a storage rack 1, a guide machine 101, a yarn bundling machine 102, a gluing device 4, a drying device 5, and a cutting device (not shown). The storage rack 1 adopts a stainless steel frame structure, on which are provided several storage rollers 103 for storing fiber rovings. Each storage roller 103 is independently connected to a drive motor to ensure that the fiber can be continuously unwound at a stable speed. The fiber rovings on the storage rollers 103 are made of polyester fiber. The guide machine 101 is located on one side of the storage rack 1, and is provided with an active guide roller and a driven guide roller. The surface of the guide roller is covered with a rubber layer to increase friction. It should be noted that the guide machine 101, the yarn bundling machine 102, the gluing device 4, the drying device 5, and the cutting device are all standard equipment that can be purchased commercially by those skilled in the art. This solution does not improve or innovate them, but only applies them. Therefore, the working principle of each device will not be described in detail.

[0024] Meanwhile, a special beating mechanism is set between the wire bundling machine 102 and the feeder 101. Its working principle is to loosen the fibers fully by mechanical beating, thereby improving the quality of subsequent wire bundling.

[0025] Specifically, a base plate 2 is set between the wire harness machine 102 and the feeder 101, and a support frame 201 is welded to the top of the base plate 2 to provide a stable support foundation for the tapping mechanism.

[0026] The beating mechanism includes a beating rod 202, a first connecting rod 203 fixedly connected to the bottom of the beating rod 202, an elastic element 204, and a drive assembly for intermittently compressing the elastic element 204 by the beating rod 202. One side of the elastic element 204 abuts against the top of the support frame 201, and the other side of the elastic element 204 abuts against the bottom of the first connecting rod 203. When the drive assembly acts on the beating rod 202, the beating rod 202 moves downward, compressing the elastic element 204 and storing force; when the drive assembly does not act on the beating rod 202, the elastic element 204 releases its elastic force, pushing the beating rod 202 to move in the opposite direction, thereby beating the fibers.

[0027] Compared to rigid beating, this elastically driven beating method ensures sufficient beating force to disperse adhering fibers while using elastic cushioning to prevent excessive impact on the fiber roving by the beating rod 202, thereby reducing fiber breakage and achieving a "gentle yet effective" dispersion effect. Simultaneously, this method also makes the movement trajectory of the beating rod 202 more regular, and the beating frequency and force more uniform, further improving the consistency of fiber dispersion.

[0028] Next, the beater 202 can be made of rigid plastic, with two symmetrically arranged extension rods 205 welded to its bottom. The extension rods 205 are detachably fixed to the first connecting rod 203 by bolts 206. By adjusting the depth of the extension rods 205 inserted into the first connecting rod 203, the working height of the beater 202 can be changed to adapt to different fiber roving conveying needs. Furthermore, this detachable design facilitates the replacement of suitable beaters 202 according to different fiber characteristics, thereby improving practicality.

[0029] To ensure the accuracy of the striking motion, guide rods 207 are fixedly connected to both sides of the bottom of the first connecting rod 203, and limit blocks 208 are fixedly connected to both sides of the support frame 201. Each guide rod 207 is slidably connected to its corresponding limit block 208. The limit blocks 208 and guide rods 207 ensure that the striking rod 202 always maintains a vertical movement trajectory, avoiding uneven striking caused by tilting, thereby improving the striking quality.

[0030] In addition, the elastic element 204 is directly sleeved on the outside of the guide rod 207, and one side of the elastic element 204 abuts against the top of the limiting block 208. This ensures that the compression and rebound process of the elastic element 204 always proceeds along the predetermined axis, avoiding bending deformation and failure caused by eccentric force, thereby extending the service life of the elastic element 204.

[0031] In this embodiment, the drive assembly includes a second connecting rod 3 fixedly connected to the bottom of each guide rod 207, an L-shaped plate 301 fixedly connected to the bottom of the second connecting rod 3 and inclined, a servo motor 302, and a rotating plate 303. A motor base 304 is fixedly connected to the side of the support frame 201. The servo motor 302 is fixedly connected to the motor base 304. The servo motor 302 can be fixedly connected to the motor base 304 by bolts 206. The output end of the servo motor 302 is fixedly connected to the rotating plate 303. A rotating wheel 305 is provided on the rotating plate 303. The rotating wheel 305 is slidably connected to one side of the L-shaped plate 301.

[0032] In use, the operator drives the servo motor 302, whose output drives the rotating plate 303 to rotate. The rotation of the rotating plate 303, in turn, drives the rotating wheel 305 to rotate. When the rotating wheel 305 contacts the L-shaped plate 301, it causes the L-shaped plate 301 to move downwards. The L-shaped plate 301 pushes the second connecting rod 3 downwards, and the second connecting rod 3, through the guide rod 207, drives the first connecting rod 203 downwards. Simultaneously, the first connecting rod 203 compresses the elastic element 204, storing energy. When the rotating wheel 305 disengages from the L-shaped plate 301, the elastic element 204 releases the stored energy, pushing the striking rod 202 to move in the opposite direction, thereby striking the fiber surface and dispersing it.

[0033] The drive component in this solution only requires the servo motor 302 to rotate in one direction to realize the reciprocating movement of the striking bar 202, thereby reducing the problem of shortened service life of the servo motor 302 due to frequent forward and reverse rotation, and ensuring the stability of the movement of the servo motor 302.

[0034] Secondly, the rotating wheel 305 is rotatably connected to the rotating plate 303. The rotating wheel 305 has a cylindrical shape. This design can convert sliding friction into rolling friction, reduce wear and operating noise, and improve the service life and operational stability of the equipment.

[0035] The complete production process of fiber pen tips:

[0036] 1. Raw material unwinding and conveying: Several rolls of polyester fiber roving are respectively installed on the storage rollers 103 of the storage rack 1. The ends of each roll of fiber roving are unwound, and they are combined and introduced between the two sets of conveying rollers of the feeder 101. The drive motor of the feeder 101 is started, and the conveying rollers rotate at a uniform speed, driving the fiber roving towards the yarn bundling machine 102. During the conveying process, the tension adjustment device of the feeder 101 controls the fiber roving to maintain a suitable tension, which avoids both excessive looseness leading to accumulation and excessive tightness causing fiber breakage.

[0037] 2. Fiber Dispersion Process: While the feeder 101 conveys the fiber roving, the operator drives the servo motor 302. The output of the servo motor 302 drives the rotating plate 303 to rotate, which in turn drives the rotating wheel 305 to rotate. When the rotating wheel 305 contacts the L-shaped plate 301, the rotating wheel 305 drives the L-shaped plate 301 to move downward. The L-shaped plate 301 pushes the second connecting rod 3 downward, and the second connecting rod 3 drives the first connecting rod 203 downward through the guide rod 207. At the same time, the first connecting rod 203 compresses the elastic element 204, storing energy. When the rotating wheel 305 disengages from the L-shaped plate 301, the elastic element 204 releases the stored energy, pushing the striking rod 202 to move in the opposite direction, thereby striking the fiber surface and dispersing it. This breaks the adhesion between the fiber rovings, dispersing the originally sticky small fiber bundles into independent single fibers, ensuring that the fiber rovings entering the bundling machine 102 are loose and uniform, providing a guarantee for the subsequent bundling quality.

[0038] 3. Bundling and forming: The fiber rovings that have been beaten and dispersed are continuously fed to the feed port of the bundling machine 102. The bundling mold inside the bundling machine 102 gathers the loose fiber rovings and forms cylindrical fiber strips of a specified diameter.

[0039] 4. Impregnation: The bundled cylindrical fiber strips are discharged from the outlet of the fiber bundling machine 102 and directly introduced into the glue tank of the glue coating machine. The glue tank is filled with water-based acrylic resin to ensure that the glue is evenly adsorbed on the surface of each fiber and in the gaps between the fibers.

[0040] 5. Drying and Shaping: The impregnated fiber strips are conveyed into the drying equipment. The fiber strips move at a uniform speed within the drying channel, consistent with the speed of the feeder 101, to prevent stretching or accumulation of the fiber strips. The adhesive is cured by the heating effect of hot air within the drying device 5. The cured fiber strips have a stable structure, are not easily loosened, and meet the requirements for subsequent cutting and processing.

[0041] 6. Cutting the finished product: After drying and shaping, the fiber strip is output from the drying channel and enters the cutting device. According to the preset length of the finished pen tip, the cutting device cuts the fiber strip to a fixed length. The cut product is the finished fiber pen tip.
