Description

Technical Field

[0002] Carbon fiber prepreg is prepared by compounding epoxy resin on carbon fiber using high pressure and high temperature technology. Therefore, carbon fiber yarn is needed as raw material to process carbon fiber prepreg. When preparing carbon fiber prepreg, a creel is needed to place the yarn tube, so that the yarn tube can continuously rotate on the creel to transport the carbon fiber yarn. The carbon fiber yarn is then compounded with epoxy resin after passing through the yarn spreading mechanism, pulling mechanism, gluing mechanism, heating mechanism, cooling mechanism, winding mechanism and other equipment to finally make carbon fiber prepreg.

[0003] After searching, the Chinese utility model with the authorization announcement number CN217756286U discloses a carbon fiber prepreg yarn rack, which specifically includes a support frame, a flip assembly is arranged on the support frame, and the flip assembly includes a rotating support rod, which is rotatably plugged into the upper end of the support frame, and the rotating support rod is arranged through the upper end of the support frame, and an embedded plug rod is embedded on the rotating support rod; a pull cap is arranged at the outer end of the embedded plug rod, and a pull spring is sleeved on the embedded plug rod, and the two ends of the pull spring are respectively fixedly connected to the support frame and the pull cap. This patent can limit the position of multiple yarn drums, avoid the yarn drums from shaking and deviating forward and backward, and ensure the stable limited rotation and release of the yarn drums; when the carbon fiber yarns on multiple yarn drums are used up, the yarn drums can be disassembled in batches, and the disassembly and separation speed is faster, which improves the efficiency of replacing yarn drums on the yarn rack.

[0025] The improvement of the utility model lies in that: the toggle mechanism 5 is used to toggle the yarn tube on the corresponding yarn tube placing rod 3, that is, the yarn tube can be unloaded individually, and the driving mechanism 7 can make all the toggle mechanisms 5 to toggle all the yarn tubes at the same time, that is, all the yarn tubes can be unloaded synchronously, and the unlocking component 8 can release the transmission connection with the driving mechanism 7, that is, when the driving mechanism 7 is working, the corresponding toggle mechanism 5 does not work.

[0026] When it is necessary to replace a bobbin on a bobbin placing rod 3 separately, directly operate the corresponding toggle mechanism 5, which includes a toggle rod 51 and a limiting ring body 52. ​​Two limiting ring bodies 52 are provided, and a connecting rod 521 is provided on the outer wall of the limiting ring body 52. ​​The arc-shaped convex plate 4 is provided with a plurality of slideways 42 distributed at an angle, and the arc-shaped fixed plate 6 is provided with a plurality of slide holes distributed at equal angles. The toggle rod 51 is slidably set in the slideway 42 and the slide hole, and two connecting rods 521 are spaced apart on the outer wall of the head end of the toggle rod 51 along the length direction of the toggle rod 51, and the two limiting ring bodies 52 are slidably set on the bobbin placing rod 3.

[0027] Directly push the lever 51, the lever 51 drives the two connecting rods 521 to move synchronously, and the two connecting rods 521 drive the two limiting rings 52 to move on the corresponding bobbin placing rods 3. The limiting ring 52 near one end of the arc-shaped yarn rack 2 can push the yarn bobbin to translate on the yarn bobbin placing rod 3 as the lever 51 moves, and then the yarn bobbin can be detached from the yarn bobbin placing rod 3, and then the new yarn bobbin can be inserted into the yarn bobbin placing rod 3. During insertion, the yarn bobbin can press the limiting ring 52 near one end of the arc-shaped yarn rack 2 to move in the opposite direction, and the limiting ring 52 away from one end of the arc-shaped yarn rack 2 can limit the yarn bobbin on the yarn bobbin placing rod 3, and the lever 51 can return to its original position.

[0028] Furthermore, an outer wall at one end of the connecting rod 521 is provided with an external thread and two nuts 522 cooperating with the external thread, and a through hole is provided on the lever 51 for the connecting rod 521 to pass through, so that the limiting ring body 52 is easy to disassemble and maintain.

[0029] Furthermore, a first handle 511 is provided at the tail end of the lever 51 , and the first handle 511 can improve the convenience of pushing the lever 51 .

[0030] When it is necessary to replace the yarn bobbins on multiple yarn bobbin placing rods 3, the corresponding toggle mechanism 5 is driven to work through the cooperation of the driving mechanism 7 and the unlocking assembly 8. The driving mechanism 7 includes an arc-shaped contact plate 71 and a push rod 72. The arc-shaped contact plate 71 is provided with a guide hole 711 that slides with the toggle rod 51. The push rod 72 is vertically arranged on the side wall of the arc-shaped contact plate 71. The arc-shaped contact plate 71 is arranged on all the toggle rods 51 through the guide hole 711. The arc-shaped fixing plate 6 is provided with a through hole for the push rod 72 to pass through.

[0031] The unlocking assembly 8 includes a limit block 81, a screw rod 82 and a handle 83. The limit block 81 has a polygonal cross-section. An inner groove 512 that slides with the limit block 81 is provided on an outer wall on one side of the middle part of the lever 51. A threaded hole that cooperates with the screw rod 82 is provided on the outer wall on the other side of the middle part of the lever 51, and the threaded hole is connected to the inner groove 512. The limit block 81 is arranged in the inner groove 512, and the screw rod 82 is arranged in the threaded hole. One end of the screw rod 82 is rotatably arranged on the outer wall of the limit block 81, and the handle 83 is arranged on the other end of the screw rod 82. An avoidance groove 712 for avoiding the screw rod 82 and the handle 83 is provided on the hole wall of the guide hole 711.

[0032] First, unlock the unlocking assembly 8 at the position corresponding to the yarn tube that does not need to be removed, and rotate the handle 83 by hand. In order to avoid slipping, an anti-slip pattern is provided on the handle 83. The handle 83 drives the screw rod 82 to rotate, and the screw rod 82 can move outward using the threaded hole. The screw rod 82 pulls the limit block 81 to move into the inner groove 512, and then the limit block 81 is retracted into the inner groove 512. Then, by pushing the push rod 72, in order to improve the convenience of pushing the push rod 72, a second handle 721 is provided at the tail end of the push rod 72, and the push rod 72 drives the arc When the arc-shaped contact plate 71 moves toward the arc-shaped yarn rack 2, the limit block 81 on the unlocked lever 51 can contact the arc-shaped contact plate 71, and then the lever 51 can move synchronously with the arc-shaped contact plate 71. The limit block 81 on the unlocked lever 51 is retracted into the inner groove 512, so it will not contact the arc-shaped contact plate 71, and the screw rod 82 and the handle 83 can both pass through the avoidance groove 712, that is, the screw rod 82 and the handle 83 will not drive the lever 51 to move synchronously, so that the yarn bobbin can be selectively replaced.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
