Description

Technical Field

[0001] This invention relates to the field of glass fiber manufacturing feeding components, and in particular to a novel energy-saving glass fiber manufacturing feeding component. Background Technology

[0002] Glass fiber is a high-performance inorganic non-metallic material with advantages such as good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength. It is made from six minerals—pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia—through high-temperature melting, drawing, winding, and weaving processes. The diameter of its monofilaments ranges from a few micrometers to over twenty micrometers, and each bundle of fiber consists of hundreds or even thousands of monofilaments. Glass fiber is commonly used as a reinforcing material, electrical insulation material, and thermal insulation material in composite materials and is widely used in various sectors of the national economy. Currently, the production process of glass fiber mainly includes: crystal raw material selection, crushing, purification, melting and drawing, hydrogen-oxygen flame melting, fine drawing, bundling and adding sizing agent, far-infrared drying, twisting, finished yarn inspection, and packaging. Among these processes, the crystal raw material selection and crushing process is the most energy-intensive. How to reduce energy consumption to achieve the desired raw material processing is a common concern in this field.

[0003] Currently, Chinese patent application CN212711432U discloses a plate-type feeding device for glass fiber manufacturing, including a feeding section, a feeder housing, a feeding device, a robotic arm device, a support plate, a large particle unloading section, and a small particle unloading section; the feeding section is made of steel, with its upper part being funnel-shaped and its lower part being a pipe structure; the pipe of the feeding section is connected to the feeder housing; high-purity silica or crystal enters the feeder housing through the feeding section;

[0004] Existing patent applications use robotic arms to pick out larger high-purity silica or crystal particles and place them in a large-particle unloading section for natural cooling, while smaller high-purity silica or crystal particles are fed into a small-particle unloading section and then cooled by subsequent equipment. However, using robotic arms in conjunction with vision detection to separate and pick out larger high-purity silica or crystal particles is costly and inefficient, and does not effectively reduce energy consumption, thus requiring improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a novel energy-saving feeding component for glass fiber manufacturing, which has the advantages of low cost and good energy-saving effect.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a novel energy-saving feeding component for glass fiber manufacturing, comprising a base; a rotating disk and a rotation drive component for driving the rotating disk to rotate are coaxially rotatably connected on the base; four sets of hemispherical screens are evenly spaced and rotatably connected on the rotating disk along the circumferential direction; two sets of screens are synchronously rotated based on a synchronous rotation component; a raw material input component and an arc-shaped stirring rod that extends into the screen to stir the raw material and increase the screening efficiency are respectively fixedly provided on the base directly above the feeding station and the screening station; a feeding conveyor line and a screening conveyor line are respectively provided on the base directly below the feeding station and the screening station.

[0007] The present invention is further configured such that: the synchronous rotation assembly is provided in two sets and is asymmetrically arranged at both ends of the base; the synchronous rotation assembly includes a rotation shaft symmetrically fixedly connected to both ends of the screen along the diameter direction and a first synchronous drive gear coaxially fixedly connected to the rotation shaft; a second synchronous drive gear cooperating with the first synchronous drive gear is rotatably connected to the base; and a synchronous drive motor that drives the second synchronous drive gear to rotate is fixedly connected to the base.

[0008] The present invention is further configured such that: the rotary drive assembly includes a rotary drive gear ring coaxially sleeved and fixedly connected to the rotary disk and a rotary drive motor fixedly connected to the base, wherein a rotary drive gear cooperating with the rotary drive gear ring is fixedly connected to the rotary shaft of the rotary drive motor.

[0009] The present invention is further configured such that both the synchronous drive motor and the rotary drive motor are servo motors.

[0010] The present invention is further configured such that: the lifting and rotating assembly includes a lifting cylinder fixedly disposed on the base in a vertical direction and a mounting base fixedly connected to the telescopic end of the lifting cylinder; a stirring motor is fixedly connected to the mounting base; and the arc-shaped stirring rod is fixedly connected to the rotating shaft of the stirring motor.

[0011] The present invention is further configured such that: the raw material input component includes a feeding pipe fixedly connected to the base and a stirring cylinder coaxially fixedly connected to the feeding pipe; the stirring pipe is provided with a stirring component for mixing raw materials and preventing raw materials from clumping; and the top of the stirring cylinder is fixedly connected with a conveying pipe for adding raw materials into the stirring cylinder.

[0012] The present invention is further configured such that: the stirring assembly includes a stirring shaft rotatably connected to the stirring drum along the vertical direction and a rotary motor fixedly connected to the stirring shaft for driving the stirring shaft to rotate; and a plurality of stirring blocks are uniformly arranged on the stirring shaft along the vertical direction.

[0013] The present invention is further configured such that a baffle is provided between adjacent feeding conveyor lines and screening conveyor lines.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. Four sets of screens are arranged circumferentially on a rotating disc. The two sets of screens symmetrically positioned horizontally form the feeding station, and the two sets of screens symmetrically positioned vertically form the screening station. Feeding conveyor lines and screening conveyor lines are respectively located directly below the feeding and screening stations. The two sets of screens at the feeding station have their openings facing upwards and are horizontally oriented. The two sets of screens at the screening station are positioned vertically or with their openings facing downwards and are horizontally oriented. Raw materials are poured into the two sets of screens at the feeding station via a raw material input component. Simultaneously, a lifting and rotating component drives an arc-shaped stirring rod to descend and extend into the screen, stirring the raw materials inside. At this point, smaller particles fall onto the feeding conveyor line, completing the screening and feeding process, while larger particles remain within the screen. The material remains inside the screen. After screening, the rotary drive assembly rotates the rotating disk, thereby changing the position of the screen at the feeding station and the screening station. Simultaneously, the synchronous drive motor of the synchronous rotation assembly drives the second synchronous drive gear to rotate, which in turn drives the first synchronous drive gear to rotate, thus controlling the angle of the screen. When the screen at the feeding station moves to the screening station, it rotates to the vertical direction. The large-diameter raw materials screened out inside the screen fall onto the screening conveyor line due to gravity and are discharged. When the screen at the screening station moves to the feeding station, it rotates to the horizontal direction. Similarly, the raw materials are screened at the screening station. The structure is simple, the screening cost is low, and it can achieve one-time screening of large batches of raw materials, avoiding the need for secondary screening and improving the separation efficiency.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example:

[0023] refer to Figures 1 to 4 A novel energy-saving feeding assembly for glass fiber manufacturing includes a base 1, a rotating disk 2 rotatably connected coaxially to the base 1, and a rotation drive assembly 3 fixedly mounted to drive the rotating disk 2 to rotate. Four sets of hemispherical screens 4 are evenly spaced and rotated along the circumference of the rotating disk 2. The station containing two symmetrical sets of screens 4 in the horizontal direction is the feeding station, and the station containing two symmetrical sets of screens 4 in the vertical direction is the screening station. The symmetrical sets of screens 4 rotate synchronously based on a synchronous rotation assembly 5. The component 5 is provided in two sets and is asymmetrically arranged at both ends of the base 1. The movement between the two pairs of screens 4 is independent. The base 1 is fixedly provided with a raw material input component 6 and an arc-shaped stirring rod 8 that extends into the screen 4 to stir the raw material and increase the screening efficiency, based on the lifting and rotating component 7. The base 1 is provided with a feeding conveyor line 9 and a screening conveyor line 10 directly below the feeding station and the screening station, respectively. A baffle 11 is provided between adjacent feeding conveyor lines 9 and screening conveyor lines 10 to avoid mixing between the screened raw materials.

[0024] refer to Figure 1 and Figure 2Specifically, the synchronous rotation assembly 5 includes a rotating shaft 51 symmetrically fixedly connected to both ends of the screen 4 along its diameter, and a first synchronous drive gear 52 coaxially fixedly connected to the rotating shaft 51. A second synchronous drive gear 53, which cooperates with the first synchronous drive gear 52, is rotatably connected to the base 1, and a synchronous drive motor 54, which drives the second synchronous drive gear 53 to rotate, is fixedly connected to it. The synchronous drive motor 54 of the synchronous rotation assembly 5 drives the second synchronous drive gear 53 to rotate, which in turn drives the first synchronous drive gear 52 to rotate, thereby controlling the angle of the screen 4. The rotation drive assembly 3 includes a rotation drive gear ring 31 coaxially sleeved and fixedly connected to the rotating disk 2, and a gear ring fixedly connected to the base 1. A rotary drive motor 32 has a rotary drive gear 33 fixedly connected to its rotating shaft 51, which engages with the rotary drive gear ring 31. The rotary drive motor 32 drives the rotary drive gear 33, which in turn drives the rotary drive gear ring 31 and the rotating disk 2 to rotate, thereby achieving the switching of the screen 4 station. In this embodiment, both the synchronous drive motor 54 and the rotary drive motor 32 are servo motors, which makes it easier to accurately control the rotation angle of the rotating disk 2 and the angle of the screen 4 relative to the horizontal plane. At the same time, the rotation data of the synchronous drive motor 54 and the rotary drive motor 32 can be coupled, and the rotation timing of the synchronous drive motor 54 and the rotary drive motor 32 can be controlled in real time by the controller.

[0025] refer to Figure 1 and Figure 3 Specifically, the lifting and rotating assembly 7 includes a lifting cylinder 71 fixedly mounted on the base 1 in a vertical direction and a mounting base 72 fixedly connected to the telescopic end of the lifting cylinder 71. A stirring motor 73 is fixedly connected to the mounting base 72, and an arc-shaped stirring rod 8 is fixedly connected to the rotating shaft 51 of the stirring motor 73. The raw material is poured into the two sets of screens 4 located at the unloading station through the raw material input assembly 6. At the same time, the lifting and rotating assembly 7 drives the arc-shaped stirring rod 8 to descend and extend into the screen 4 to stir the raw material in the screen 4. At this time, the raw material with smaller particle size in the screen 4 falls onto the unloading conveyor line 9 to complete the screening and unloading, while the raw material with larger particle size is retained in the screen 4.

[0026] refer to Figure 1 and Figure 4Specifically, the raw material input component 6 includes a feeding pipe 61 fixedly connected to the base 1 and a stirring drum 62 coaxially fixedly connected to the feeding pipe 61. A stirring component 63 is provided inside the stirring pipe to mix the raw materials and prevent them from clumping. A conveying pipe 64 for adding raw materials into the stirring drum 62 is fixedly connected to the top of the stirring drum 62. The stirring component 63 includes a stirring shaft 631 coaxially rotatably connected to the stirring drum 62 in the vertical direction and a rotary motor 632 fixedly connected to the stirring shaft 631 for driving the stirring shaft 631 to rotate. Several stirring blocks 633 are evenly arranged on the stirring shaft 631 in the vertical direction. At least one raw material is fed into the stirring drum through the conveying pipe 64. The rotary motor 632 drives the stirring shaft 631 to rotate, which in turn drives the stirring rod to rotate, thereby stirring the raw materials in the stirring drum 62, thus mixing the raw materials and preventing them from sticking together and affecting the screening effect.

[0027] Brief description of the usage process: The raw material input component 6 pours the raw material into the two sets of screens 4 located at the unloading station. At the same time, the lifting and rotating component 7 drives the arc-shaped stirring rod 8 to descend and extend into the screen 4 to stir the raw material in the screen 4. At this time, the raw material with smaller particle size in the screen 4 falls onto the unloading conveyor line 9 to complete the screening and unloading, while the raw material with larger particle size is retained in the screen 4. After screening, the rotation drive component 3 drives the rotating disk 2 to rotate, thereby changing the position of the screen 4 located at the unloading station and the screening station. At the same time, the synchronous drive motor 54 of the synchronous rotation component 5 drives the second synchronous drive gear 53 to rotate, which in turn drives the first synchronous drive gear 52 to rotate, thereby controlling the angle of the screen 4. When the screen 4 at the unloading station moves to the screening station, the screen 4 rotates to the vertical direction. The large-particle raw material screened out in the screen 4 falls onto the screening conveyor line 10 due to gravity and is discharged. When the screen 4 at the screening station moves to the unloading station, the screen 4 rotates to the horizontal direction to repeat the screening of raw materials.
