Description

Technical Field

[0001] The utility model relates to the technical field of impregnation technology, in particular to automatic degassing equipment for a prepreg impregnation machine. Background Art

[0002] The impregnation process is a common material surface modification method, which changes the physical and chemical properties of the surface by immersing the material in a specific solution. At present, bubbles will form between the prepreg and the release paper during the impregnation production process, and it is necessary to manually puncture the bubbles to remove them. This debubbling method is not only inefficient, but also prone to omissions, which has a great impact on the molding quality of the prepreg. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an automatic degassing device for a prepreg impregnation machine, which can accurately remove bubbles in various parts of the prepreg without omission.

[0004] To this end, the technical solution of the utility model is: an automatic defoaming device for a prepreg impregnation machine, comprising at least one pair of rollers that cooperate with each other, the first roller is composed of a first core shaft and an isolation sleeve, the outer surface of the first core shaft is embedded with a plurality of spikes, and the isolation sleeve is sleeved on the outside of the first core shaft; the isolation sleeve is provided with holes for each spike to penetrate, and the isolation sleeve is elastic.

[0005] On the basis of the above scheme and as a preferred scheme of the above scheme: when the isolation sleeve is not under pressure, the spikes are hidden in the outer surface of the isolation sleeve, and when the isolation sleeve is compressed and retracted, the spikes are exposed on the outside of the isolation sleeve.

[0006] On the basis of the above solution and as a preferred solution of the above solution: the initial thickness of the isolation sleeve is ≥ the height of the spikes.

[0007] On the basis of the above solution and as a preferred solution of the above solution: the isolation sleeve is made of rubber, silicone or sponge.

[0008] On the basis of the above solution and as a preferred solution of the above solution: the first core shaft and the spikes are both made of rigid materials.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the first roller and the second roller work in coordination, the second roller includes a second mandrel, and the surface of the second mandrel is smooth.

[0010] The first roller and the second roller are placed up and down. In a natural state, the spikes on the first roller are hidden in the isolation sleeve. When the prepreg with a smooth surface passes through the first roller, the prepreg will not squeeze the isolation sleeve, and the spikes on the first roller will not pierce out, so the defoaming equipment will not play a role and will not affect the normal prepreg production.

[0011] When the prepreg with bubbles on the surface passes through, the protruding bubbles will squeeze the isolation sleeve, causing the isolation sleeve to shrink inward, exposing the spikes hidden inside the isolation sleeve, and automatically puncturing and removing the bubbles.

[0012] Compared with the prior art, the utility model has the following beneficial effects: bubbles are removed by using a roller with spikes, the spikes are wrapped by an isolation sleeve, and only bubbles can expose the spikes, thereby achieving precise positioning, and removing bubbles from all parts of the entire surface of the prepreg without omissions; while achieving precise positioning, the isolation sleeve can protect other parts of the prepreg, reducing prepreg surface quality problems caused by inaccurate control of the position of manual bubble puncture.

[0017] In the description of the present invention, it should be noted that directional words, such as the terms "center", "lateral (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present invention.

[0018] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. Therefore, the definition of "first" and "second" features can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "several" and "a number" is two or more, unless otherwise clearly and specifically defined.

[0019] See the attached drawings. The automatic defoaming equipment for the prepreg impregnation machine described in this embodiment includes a pair of rollers that cooperate with each other. The first roller 1 and the second roller 2 work in cooperation. The second roller 2 includes a second mandrel, and the surface of the second mandrel is smooth. The first roller 1 is composed of a first mandrel 11 and an isolation sleeve 3. The outer surface of the first mandrel 11 is embedded with a plurality of spikes 12. The first mandrel 11 and the spikes 12 are both steel structures. After the spikes come into contact with the bubbles, they can puncture the bubbles; the isolation sleeve 3 is sleeved on the outside of the first mandrel 11. The isolation sleeve 3 can be made of elastic materials such as rubber, silicone, sponge, etc., so that the isolation sleeve can wrap the spikes and shrink under pressure, so that the spikes are exposed. Finally, after being unpressurized, it rebounds and resets to continue wrapping the spikes.

[0020] The isolation sleeve 3 is provided with holes for each spike 12 to penetrate, and the initial thickness of the isolation sleeve 3 is slightly larger than the height of the spike 12. That is to say, when the isolation sleeve 3 is not under pressure, the spike 12 will be hidden in the outer surface of the isolation sleeve 3, and the spike 12 cannot be felt from the outside. When the isolation sleeve 3 is under pressure, the isolation sleeve 3 will shrink, and at this time, the rigid spike 12 will be exposed on the outside of the isolation sleeve 3.

[0021] A roller with spikes is used to remove bubbles. The spikes are wrapped in an isolation sleeve, and only bubbles can expose the spikes, so that precise positioning can be achieved and bubbles in various parts of the entire surface of the prepreg can be removed without omission. While achieving precise positioning, the isolation sleeve can protect other parts of the prepreg and reduce prepreg surface quality problems caused by inaccurate control of the position of manual bubble puncture.

[0022] When using:

[0023] 1) The first roller 1 and the second roller 2 are placed up and down, and in a natural state, the spikes 12 on the first roller 1 are hidden in the isolation sleeve 3;

[0024] 2) The prepreg 4 and the release paper after the impregnation production process pass between the first roller 1 and the second roller 2;

[0025] 3) When the prepreg 4 with a smooth surface passes through the first roller 1, the prepreg 4 will not squeeze the isolation sleeve 3, and the spikes 12 on the first roller 1 will not pierce out, and the defoaming device will not play a role, and will not affect the normal prepreg production;

[0026] 4) When the prepreg with bubbles 41 on the surface passes through, the protruding bubbles 41 will squeeze the isolation sleeve 3, causing the isolation sleeve 3 to shrink inward, and the spikes 12 hidden inside the isolation sleeve 3 are exposed, automatically puncturing and removing the bubbles 41;

[0027] 5) When the bubble 41 is cleared, the isolation sleeve 3 will automatically rebound and continue to wrap the spike 12, waiting for the arrival of the next bubble.

[0028] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
