When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] like Figures 1 to 8 The off-line intermittent powdering device for carbon fiber fabric shown comprises: a support frame 10 and two pairs of guide assemblies 20, the support frame 10 is arranged opposite to the powder outlet end of the powdering machine 01, and has a powdering table 10a for the carbon fiber fabric to pass through, and the two pairs of guide assemblies 20 are arranged opposite to each other and are located between the powdering machine 01 and the powdering table 10a;

[0032] Each guide assembly 20 includes a baffle 21 and two mounting plates 22. The mounting plates 22 are respectively fixed on both sides of the support frame 10. The two ends of the baffle 21 are respectively connected to the two support frames 10. The baffle 21 is tilted toward the guide assembly 20 on the other side. The distance between the two relatively arranged baffles 21 close to the powder spreading machine 01 is greater than the distance between the two sides close to the powder spreading table 10a.

[0033] The utility model sets two pairs of guide components 20 between the powder sprinkler 01 and the powder sprinkler table 10a, and uses the inclined guide plates to make the powder sprinkled by the powder sprinkler 01 first pass through the guidance and collection effect of the two guide plates, and then accurately fall on the surface of the carbon fiber fabric, thereby ensuring the accuracy, concentration and stability of the powder sprinkler position; the state of the carbon fiber fabric after powder sprinkled can meet the production requirements, and the utility model is highly practical.

[0034] It should be noted that the baffle 21 is usually made of stainless steel, which has a certain rigidity and hardness, and can also effectively prevent the adhesion of powders such as resin, thereby ensuring the powdering effect.

[0035] Based on the above embodiment, the inclination angle between the baffle 21 and the powder sprinkling table 10a can be adjusted, and the distance between the two baffles 21 close to the powder sprinkling table 10a can be adjusted; it can be adjusted according to actual powder sprinkling needs to ensure that powder sprinkling states of different widths and thicknesses are formed.

[0036] Preferably, the inclination angle between the baffle 21 and the powder sprinkling table 10a is 60°; the distance between the two baffles 21 close to the powder sprinkling table 10a is 3 mm. When the baffle 21 is in this position, the guiding effect of the baffle 21 on the resin powder is optimal, and the powder can be evenly, stably and accurately sprinkled at the set position.

[0037] On the basis of the above embodiment, four adjustment holes 22a are provided on the mounting plate 22, and two adjustment holes 22a arranged in the height direction of the mounting plate 22 form a group, and the two groups of adjustment holes 22a are arranged along the width direction of the mounting plate 22, and the adjustment holes 22a are oblong, and each end of the baffle 21 has two connectors 21a corresponding to the two groups of adjustment holes 22a, and each connector 21a is connected to any one of the corresponding group of adjustment holes 22a; it should be noted that the direction in which the carbon fiber fabric travels is set to the width direction of the mounting plate 22, that is, two groups of oblong adjustment holes 22a are arranged side by side along the width direction on the mounting plate 22, and the inclination angle of the baffle 21 and the relative distance between the baffle 21 and the carbon fiber fabric can be changed by changing the relative positions of the two connectors 21a at the corresponding adjustment holes 22a, thereby controlling the range of powder sprinkling, and when the baffle 21 is closer to the cloth surface of the carbon fiber fabric and the inclination angle is larger, the range of resin powder falling is more concentrated, otherwise it is relatively dispersed.

[0038] On the basis of the above embodiment, in order to avoid powder hanging on the baffle 21 during the powder sprinkling process, a vibration assembly 30 is arranged on the side of the baffle 21 away from the other pair of guide assemblies 20, and the vibration assembly 30 includes a mounting block 31 and a vibrator 32. The mounting block 31 is fixedly connected to the baffle 21, and the vibrator 32 is arranged on the side of the mounting block 31 away from the baffle 21; through the transmission effect of the mounting block 31, the vibration generated by the vibrator 32 is transmitted to the baffle 21, thereby effectively ensuring the powder sprinkling effect.

[0039] On the basis of the above-mentioned embodiment, the vibrator 32 is of ball type; the ball type vibrator 32 is provided with a precision steel wire sleeve and a steel ball inside, and is sealed outside by a special aluminum alloy shell. Air is filled in to push the steel ball to rotate in the steel sleeve, and the weight of the steel ball and the distance between the center area generate centrifugal force, so that the baffle 21 vibrates evenly and constantly, and has good stability.

[0040] On the basis of the above embodiment, when the powder spreader 01 is spreading powder, a part of the resin powder will leak out from the gap between the carbon fiber fabric and the powder spreading table 10a. A recovery component 40 is arranged at the bottom of the powder spreading table 10a. The recovery component 40 includes a recovery box 41, a base frame 42, a side frame 43 and a plurality of bull's eye wheels 44. The base frame 42 and the side frame 43 are fixedly connected to the support frame 10. The recovery box 41 is a trough structure with an opening on one side, and the open end is arranged toward the side of the carbon fiber fabric away from the powder spreader 01, and is located between the side frames 43. The bull's eye wheels 44 are arranged at equal intervals along the length direction of the base frame 42 and are in sliding contact with the bottom of the recovery box 41; the position of the recovery box 41 is adjusted by the base frame 42 and the side frame 43, so that the recovery box 41 can receive the leaked resin powder. When the collection is completed, the recovery box 41 can be drawn out from the side frame 43 through the sliding contact between the bull's eye wheels 44 and the bottom of the recovery box 41, and the resin powder can be taken out for recycling, which saves materials and effectively improves the environmental protection performance.

[0041] On the basis of the above embodiment, a handle 41 a is fixed on the recycling box 41 , and the handle 41 a is located at both ends of the recycling box 41 in the length direction; it is convenient for the operator to pull out the recycling box 41 , which is simple and convenient.

[0042] On the basis of the above embodiment, a powder outlet 41b and a plug 41c are provided at the bottom of the trough body of the recovery box 41. The powder outlet 41b is set through, and the plug 41c is truncated cone-shaped, which is set in the powder outlet 41b, and the end with a larger diameter is located on the inner side of the recovery box 41; the plug 41c blocks the powder outlet 41b, thereby effectively preventing the resin powder from leaking out, and the truncated cone-shaped plug 41c can effectively prevent the plug 41c from falling out of the powder outlet 41b, thereby ensuring the stability of the connection. When the powder in the recovery box 41 is collected, the plug 41c can be pulled out to remove the resin powder from the recovery box 41, thereby improving the recovery efficiency and effect.

[0043] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention.
