Description

TECHNICAL FIELD

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

[0002] In the process of manufacturing the pultruded carbon plate, a plurality of tapes are solidified together by resin, and the tapes are wound on the winding drum. In the process of manufacturing the pultruded carbon plate, the winding drum with the tapes is coaxially sleeved on a horizontal shaft at one end of the production line, and then one end of the tapes is pulled to the winding drum at the other end of the production line. The device for solidifying the resin and the tapes together is arranged between the two ends of the production line, so that the pultruded plate is wound on the winding drum.

[0003] However, in the process of solidifying the tapes and the resin, dust and other impurities cannot exist on the tapes, otherwise the fusion of the tapes and the resin will be affected. In the process of unwinding the tapes from the winding drum, a large amount of debris will be generated due to the friction between the tapes wound on the winding drum, which will affect the air quality in the workshop. In addition, due to storage and other procedures, dust will remain on the surface of the tapes wound on the winding drum. If the dust is not treated, the fusion of the tapes and the resin will be affected. Therefore, before the fusion of the tapes and the resin, the tapes need to be cleaned in terms of the air quality in the workshop and the fusion of the tapes and the resin. However, the current technology does not consider these two factors. Therefore, the problem of air quality in the workshop is only solved by relying on workers wearing masks. The solution to the problem of dust affecting the fusion of the tapes and the resin is to install a brush on the production line to brush off the dust on the tapes. However, the dust brushed off will diffuse in the workshop, which is not desirable. SUMMARY

[0004] The present application aims to solve the above problems. The carbon fiber intelligent creel with a fiber filtering system is designed by setting a cavity on the creel body, so that the winding drum with the tapes can be installed in the cavity, and a fiber filter is arranged at the discharge hole of the cavity. The dust and debris generated in the process of conveying the tapes can be completely removed, so that the air quality in the workshop is ensured and the fusion of the tapes and the resin is ensured. The problem of dust diffusing in the workshop due to the installation of the brush on the production line and the problem of air quality in the workshop being affected due to the generation of debris in the process of releasing the untreated tapes from the winding drum are solved.

During the production, the fiber tape 18 is continuously pulled out of the cavity 2 from the fiber filter, and the fiber filter is arranged to keep the dust or debris in the cavity 2 during the pulling of the fiber tape 18, so as to prevent the dust or debris from spreading in the workshop, and ensure that the fiber tape 18 is clean (i.e. without debris and dust) for fusion with the resin.

The filter screen 8 is arranged to prevent dust in the workshop from entering the cavity 2. The negative pressure device 3 is arranged to suck the dust and debris in the cavity 2. During the process of treating the dust and debris in the cavity 2, the air flows from the outside of the frame body 1 through the filter screen 8 into the cavity 2, and then carries the dust and debris in the cavity 2 into the negative pressure device 3. Preferably, a dust and debris collecting box is arranged at the inner top of the cavity 2, the top of the collecting box is communicated with the air inlet of the negative pressure device 3, an air filter is arranged at the air inlet of the negative pressure device 3, and an opening is arranged on the side wall of the collecting box to communicate the inside of the cavity 2 with the inside of the collecting box. A gap is prearranged between the opening on the side wall of the collecting box and the bottom wall of the collecting box, so that the dust and debris can be stored in the collecting box.

[0027] As a preferred mode, the drum shaft 4 is horizontally arranged, one end of the drum shaft 4 is fixedly connected with the side wall of the cavity 2, and the other end is a free end. In this way, the drum wound with the fiber tape 18 can be easily sleeved on the drum shaft 4.

[0028] Preferably, a plurality of opening doors 7 are arranged on the frame body 1, and one opening door 7 corresponds to one drum shaft 4. In this way, when the fiber tape 18 is replaced, only the corresponding opening door 7 needs to be opened, and all the drum shafts 4 do not need to be fully exposed to the air outside the cavity 2.

[0029] As a preferred mode, the upper end surface of the reel hanging shaft 4 is provided with a gravity sensor 9, the gravity sensor 9 is signal connected with an indicating lamp 10, and each of the switch doors 7 is provided with one indicating lamp 10.

[0030] As a preferred mode, as shown in the figure, Figure 4 the fiber filter comprises a main cylinder 11 with both ends open, a secondary cylinder 12 with both ends open, 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 into the main cylinder 11 between both ends, a soft elastic sleeve 13 in the shape of a cylinder with both ends open is coaxially arranged in the main cylinder 11, the outer circumferential surface of one end of the soft elastic sleeve 13 is fixedly and tightly connected with the inner circumferential surface between both ends of the secondary cylinder 12, the outer circumferential surface of the other end of the soft elastic sleeve 13 is fixedly and tightly connected with the inner circumferential surface between both ends of the main cylinder 11, the main cylinder 11 is provided with a position limiter matched with the secondary cylinder 12, one end of the secondary cylinder 12 outside the main cylinder 11 is fixedly connected with the outer side wall of the cavity 2, and the projection of the inner circumferential surface of one secondary cylinder 12 on the outer side wall of the cavity 2 surrounds the projection of one discharge hole 5 on the outer side wall of the cavity 2. After the reel with the fiber 18 wound thereon is coaxially sleeved on the reel hanging shaft 4, one end of the fiber 18 is stretched out to the outside of the cavity 2 after passing through the discharge hole 5 and the main cylinder 11 and the secondary cylinder 12, and after these steps are handled, the main cylinder 11 is coaxially rotated relative to the secondary cylinder 12 to a certain angle, and the relative position between the main cylinder 11 and the secondary cylinder 12 is limited by the position limiter. At this time, since the soft elastic sleeve 13 is twisted in the process of coaxial rotation of the main cylinder 11 relative to the secondary cylinder 12, the soft elastic sleeve 13 wraps between both ends of the fiber 18, so that the soft elastic sleeve 13 is in close contact with the fiber 18 during the process of the fiber 18 being pulled out to the outside of the cavity 2, so that the cavity 2 is not communicated with the outside, that is, the overflow of the debris in the cavity 2 to the outside of the cavity 2 is prevented, and the dust or debris on the surface of the fiber 18 is also wiped off.

After the arrangement, the bolt 14 is screwed into the screw hole 15 to abut against the outer surface of the auxiliary cylinder 12, thereby limiting the rotation of the main cylinder 11 relative to the auxiliary cylinder 12.
