Description

Technical Field

[0001] The present application belongs to the technical field of creel manufacturing, and specifically relates to a carbon fiber intelligent creel with a fiber filtering system. Background Art

[0002] During the production process of pultruded carbon plate, a number of ribbon fibers are solidified together by resin, and the ribbon fibers are wound on a reel before solidifying with the resin. When manufacturing pultruded carbon plate, the reel with the ribbon fibers is coaxially sleeved on a horizontal axis at one end of the production line, and then one end of the ribbon fibers is pulled to the reel at the other end of the production line. A device for solidifying the resin and the ribbon fibers together is set between the two ends of the production line, so that the formed pultruded plate is wound on the reel.

[0003] During the solidification of the tape fiber and the resin, there must be no dust or other impurities on the tape fiber, otherwise it will affect the fusion of the tape fiber and the resin; and in the process of unwinding the tape fiber from the reel, due to the friction between the tape fibers wound on the reel, a lot of debris will be generated, which will affect the air in the workshop. Similarly, due to the storage and other procedures, the tape fibers wound on the reel will leave dust on the surface of the tape fibers wound on the reel. If these dusts are not processed, it will affect the fusion of the tape fiber and the resin. Therefore, before the tape fiber and the resin are fused, whether considering the air quality of the manufacturing workshop or the fusion of the tape fiber and the resin, the tape fiber needs to be cleaned. However, the current technology does not take these two factors into consideration, so the solution to the problem of workshop air quality is to rely solely on workers wearing masks; and the solution to the dust affecting the fusion of the tape fiber and the resin is to install a brush on the production line to brush off the dust on the tape fiber between the fusion of the tape fiber and the resin. The dust brushed off will spread in the workshop, so it is very undesirable. Summary of the invention

[0004] The purpose of this application is mainly to address the shortcomings of the prior art. A cavity is set on the frame body so that a reel wound with fiber can be installed in the cavity, and a fiber filter is set at the discharge hole of the cavity. A carbon fiber intelligent yarn frame with a fiber filtering system is designed, which can clean up the dust and debris generated in the process of conveying fiber, thereby ensuring both the air quality of the workshop and the fusion of fiber and resin. It solves the problem of installing a brush on the production line to brush off the dust on the fiber, resulting in the dust brushed off spreading in the workshop, and the problem of debris (hairiness, carbon filaments) generated during the release of untreated fiber from the reel, resulting in a decrease in the air quality in the workshop.

[0010] Preferably, the limiter includes a screw hole and a bolt that cooperate with each other. The screw hole is radially arranged on the main tube between the end connected to the soft elastic sleeve and the end of the main tube facing the secondary tube. One end of the screw hole is outside the main tube, and the other end is connected to the interior of the main tube.

The problem of installing a brush on the production line to brush off the dust on the tape fibers, resulting in the dust brushed off spreading in the workshop, and the problem of debris (hairiness, carbon filaments) generated during the release of untreated tape fibers from the reel, resulting in a decrease in the air quality in the workshop.

DETAILED DESCRIPTION

[0025] like Figure 1-6 As shown, a carbon fiber intelligent yarn frame with a fiber filtering system includes a frame body 1, a cavity 2 is provided on the frame body 1, a negative pressure device 3 connected to the inside of the cavity 2 is provided on the top wall of the frame body 1, a plurality of winding roller hanging shafts 4 are provided in the cavity 2, a discharge hole 5, a respirator 6, and a switch door 7 are provided on one side wall of the cavity 2, a fiber filter is provided on the frame body 1 outside the cavity 2 corresponding to each of the discharge holes 5, and a filter net 8 is provided outside the cavity 2 at the respirator 6.

[0026] In this embodiment, when in use, the rolled-up ribbon fiber 18 is coaxially sleeved on the reel hanging shaft 4, and then one end of the ribbon fiber 18 is passed through the fiber filter to the outside of the frame body, that is, connected to the reel roller for reeling the pultruded plate on the production line. After that, the resin adding device adds the resin to be fused with the ribbon fiber 18 outside the frame body 1; during the production process, the ribbon fiber 18 is continuously pulled out of the cavity 2 from the fiber filter, and the fiber filter is set so that dust or debris is left in the cavity 2 during the process of the ribbon fiber 18 being pulled out of the cavity 2, thereby preventing dust or debris from spreading in the workshop, and at the same time, it can also ensure that the ribbon fiber 18 used for fusion with the resin is clean (that is, there is no debris and dust). The switch door 7 is set to ensure the airtightness in the cavity 2 during the production process. When the ribbon fiber 18 needs to be continued, the new reel wound with the ribbon fiber 18 can be replaced on the reel hanging shaft 4 that has exhausted the ribbon fiber 18 by opening the switch door 7. The filter 8 is provided to prevent dust in the workshop from entering the cavity 2. The negative pressure device 3 is provided to absorb the dust and debris in the cavity 2. In the process of treating the dust and debris in the cavity 2, under the action of the negative pressure device 3, the airflow enters the cavity 2 from the outside of the frame body 1 through the filter 8, and then carries the dust and debris in the cavity 2 into the negative pressure device 3. Preferably, a collection box for collecting dust and debris is provided at the inner top of the cavity 2, the top of the collection box is connected to the air inlet of the negative pressure device 3, the air filter element is provided at the air inlet of the negative pressure device 3, and an opening is provided on the side wall of the collection box to connect the interior of the cavity 2 with the interior of the collection box. A preset gap is provided between the opening on the side wall of the collection box and the bottom wall of the collection box, so that dust or debris can be stored in the collection box.

[0027] As a preferred mode, the reel hanging shaft 4 is arranged horizontally, one end of the reel hanging shaft 4 is fixedly connected to the side wall of the cavity 2, and the other end is a free end. This arrangement facilitates the reel wound with the ribbon fiber 18 to be sleeved on the reel hanging shaft 14.

[0028] Preferably, the frame body 1 is provided with a plurality of switch doors 7, and one switch door 7 corresponds to one reel hanging shaft 4. In this way, when replacing the ribbon fiber 18, it is only necessary to open the corresponding switch door 7, and it is not necessary to fully contact all the reel hanging shafts 4 with the air outside the cavity 2, that is, to avoid all the reel hanging shafts 4 being fully exposed.

[0029] As a preferred mode, a gravity sensor 9 is provided on the upper end surface of the reel hanging shaft 4, and the signal of the gravity sensor 9 is connected to an indicator light 10, and each of the switch doors 7 is provided with an indicator light 10. In this way, by providing the gravity sensor 9, the amount of the remaining tape fiber 18 on the reel hanging shaft 4 is sensed; when the tape fiber 18 is about to be exhausted, the gravity sensor 9 transmits a signal to the indicator light 10, and the worker replaces the tape fiber 18 on the corresponding reel hanging shaft 4 according to the prompt of the indicator light 10.

[0030] As a preferred method, Figure 4 As shown, the fiber filter includes a main cylinder 11 with openings at both ends and a secondary cylinder 12 with openings at both ends, the inner diameter of the main cylinder 11 is larger than the outer diameter of the secondary cylinder 12, one end of the secondary cylinder 12 is inserted between the two ends in the main cylinder 11, and a cylindrical soft elastic sleeve 13 with openings at both ends is coaxially provided in the main cylinder 11, the outer circumferential surface of one end of the soft elastic sleeve 13 is tightly and fixedly connected to the inner circumferential surface between the two ends of the secondary cylinder 12, and the outer circumferential surface of the other end of the soft elastic sleeve 13 is tightly and fixedly connected to the inner circumferential surface between the two ends of the main cylinder 11, the main cylinder 11 is provided with a limiter that cooperates with the secondary cylinder 12, and one end of the secondary cylinder 12 located outside the main cylinder 11 is fixedly connected to the outer side wall of the cavity 2, and a projection of the inner circumferential surface of the secondary cylinder 12 on the outer side wall of the cavity 2 surrounds a projection of the discharge hole 5 on the outer side wall of the cavity 2. After such arrangement, after the reel wound with the fiber belt 18 is coaxially sleeved on the reel hanging shaft 4, one end of the fiber belt 18 is extended out of the cavity 2 after passing through the discharge hole 5 and the main cylinder 11 and the auxiliary cylinder 12. After completing these steps, the main cylinder 11 is coaxially rotated to a certain angle relative to the auxiliary cylinder 12, and the relative position between the main cylinder 11 and the auxiliary cylinder 12 is limited by the limiter. At this time, since the soft elastic sleeve 13 is twisted during the coaxial rotation of the main cylinder 11 relative to the auxiliary cylinder 12, the soft elastic sleeve 13 wraps around the two ends of the fiber belt 18, so that in the process of the fiber belt 18 being pulled out of the cavity 2, the soft elastic sleeve 13 is always in close contact with the fiber belt 18, so that the cavity 2 will not be connected to the outside, that is, the debris in the cavity 2 is prevented from overflowing to the outside of the cavity 2, and at the same time, it also has the function of wiping off dust or debris on the surface of the fiber belt 18. When replacing the splice fiber 18, it is only necessary to twist the main tube 11 relative to the auxiliary tube 12, and the outer circumferential surface of the soft elastic sleeve 13 will approach the inner circumferential surface of the auxiliary tube 12, thereby leaving a space for the fiber 18 to pass through the entire interior of the main tube 11, the auxiliary tube 12 and the soft elastic sleeve 13.

[0031] As a preferred mode, the stopper includes a screw hole 15 and a bolt 14 that cooperate with each other. The screw hole 15 is radially arranged on the main tube 11 between the end connected to the soft elastic sleeve 13 and the end of the main tube 11 facing the secondary tube 12. One end of the screw hole 15 is outside the main tube 11, and the other end is connected to the inside of the main tube 11. The length of the bolt 14 is greater than the difference between the outer diameter of the main tube 11 and the outer diameter of the secondary tube 12. After such arrangement, the bolt 14 is screwed into the screw hole 15 to abut against the outer surface of the secondary tube 12, thereby limiting the rotation of the main tube 11 relative to the secondary tube 12.

[0032] As a preferred embodiment, a first convex ring 16 is coaxially provided on the inner circumferential surface of the main tube 11 facing the end of the auxiliary tube 12, and a second convex ring 17 is coaxially provided on the outer circumferential surface of the auxiliary tube 12 facing the end of the main tube 11. The first convex ring 16 and the second convex ring 17 are provided in this way to prevent the main tube 11 and the auxiliary tube 12 from falling off from each other.

[0033] As a preferred embodiment, the respirator 6 is a one-way valve, and the outlet of the one-way valve is connected to the interior of the cavity 2. After such arrangement, dust in the cavity 2 is prevented from overflowing.

[0034] As a preferred embodiment, two cavities 2 are provided on the frame body 1. This design enables one frame body 1 to hold many strip fibers 18, thereby enabling one frame body 1 to cooperate with many production lines.
