Description

Technical Field

[0001] The utility model relates to the technical field of composite material production equipment, in particular to a composite material rolling device and a production line. Background Art

[0002] Glass fiber materials and carbon fiber materials have yarns in one direction and need to be stacked in a criss-cross pattern. Because the resin viscosity of carbon fiber or glass fiber is low, bubbles are easily generated between two adjacent composite materials (glass fiber layers or carbon fiber layers) and between the composite material layer and the release paper during stacking. These bubbles are not easy to discharge, which affects the normal progress of the subsequent roller-pressing composite process and the processing quality. Utility Model Content

For example, fixed connection / fixed installation can be selected according to the needs of screw connection, bolt connection, pin connection, key connection, bonding, mortise and tenon connection, welding, riveting and other methods. For example, detachable connection can be selected according to the needs of screw connection, bolt connection, threaded connection, snap connection, mortise and tenon connection, Velcro connection and other methods. The various technical features in the creation of the utility model can be combined interactively without conflicting with each other.

[0025] Reference Figure 1-2 The embodiment of the utility model provides a composite material rolling device, which includes a workbench 1, a barbed shaft 2, a barbed shaft 2 mounting frame, two rolling shafts 4, and a rolling shaft mounting frame; wherein the workbench 1 is used to support the composite material 5 to be rolled, and its arrangement direction is the same as the forward direction of the composite material 5 to be rolled; the barbed shaft 2 and the two rolling shafts 4 are arranged at intervals along the forward direction of the composite material 5 to be rolled on the forward path of the composite material 5 to be rolled, specifically, the barbed shaft 2 mounting frame is arranged on both sides of the workbench 1, and the two ends of the barbed shaft 2 are rotatably connected to the barbed shaft 2 mounting frame; the rolling shaft mounting frame is arranged on both sides of the workbench 1, and the two ends of the rolling shaft 4 are rotatably connected to the barbed shaft 2 mounting frame, and a plurality of sharp spikes 21 are evenly arranged on the surface of the barbed shaft 2 for piercing the composite material 5 to be rolled.

[0026] In this embodiment, the composite material to be rolled is composed of a top release paper, a middle composite material layer, and a bottom release paper; the middle composite material layer can be composed of multiple carbon fiber layers, multiple glass fiber layers, or different composite material layers. The function of this device is to remove bubbles in the composite material to be rolled and compound it into an integrated composite material.

[0027] In this embodiment, the working process of the composite material rolling device is as follows: the composite material 5 to be rolled moves forward on the workbench 1, and when the composite material 5 to be rolled passes the position of the thorn shaft 2, the thorn shaft 2 can rotate and pierce the composite material 5 to be rolled, so as to exhaust the bubbles on the composite material 5 to be rolled, and then when the pierced composite material 5 to be rolled passes through the two rolling shafts 4, the two rolling shafts 4 can cooperate with the composite material 5 to be rolled to perform rolling and compounding work, and at the same time, the bubbles on the composite material 5 to be rolled can be further eliminated, which has a better processing effect.

[0028] In this embodiment, a thorn shaft 2 is arranged on the path of the composite material 5 to be rolled, so that bubbles on the composite material 5 to be rolled can be punctured by the thorn shaft 2, and the composite material 5 to be rolled can be rolled by two rolling shafts 4, so that bubbles can be eliminated while completing the rolling process, thereby ensuring the processing quality.

[0029] Further, see Figure 1-2 , there are two barbed shafts 2, and the two barbed shafts 2 are arranged relatively up and down, and a gap is left between the two barbed shafts 2 for the composite material 5 to be rolled to pass through. Among them, the composite material 5 to be rolled has a certain thickness, so the spikes 21 of the barbed shaft 2 need to have a certain length when piercing the composite material 5 to be rolled, so as to ensure the working effect of puncturing and exhausting. However, the spikes 21 with too long length are easy to break, and then damage the composite material 5 to be rolled, affecting the normal processing. Now, the upper surface and the lower surface of the composite material 5 to be rolled are punctured respectively by the upper and lower barbed shafts 2, and under the premise of ensuring the puncture effect, the length of the spikes 21 can be effectively controlled, and then the normal puncture work can be ensured.

[0030] Furthermore, the spikes 21 on the two thorn shafts 2 are arranged in a mutually staggered manner. In actual production, the number of bubbles on the composite material 5 to be rolled and the position of the bubbles on the composite material 5 to be rolled cannot be determined. In order to ensure the removal effect of the bubbles on the composite material 5 to be rolled, the number of spikes 21 on the thorn shaft 2 can only be increased as much as possible to ensure the density of puncture of the composite material 5 to be rolled, but this will greatly increase the difficulty of processing the thorn shaft 2, thereby increasing the production cost. Now, by missetting the spikes 21 on the two thorn shafts 2, while ensuring the puncture density of the composite material 5 to be rolled, the requirement for the number of spikes 21 on a single thorn shaft 2 can be reduced, which can effectively reduce the production cost.

[0031] Furthermore, the length of the spike 21 is 10mm-17mm, and the diameter is 0.5mm-1.5mm. When the puncture shaft 2 punctures the composite material 5 to be rolled, the shape and size of the spike 21 is one of the important factors that determine the puncture effect. When the length of the spike 21 is too long, it is easy to break, and when the length is too short, the puncture effect is poor; when the diameter of the spike 21 is too large, a larger puncture hole will be formed, and pits will appear on the surface of the composite material after subsequent roll-compounding; when the diameter of the spike 21 is too small, the smaller puncture hole affects the exhaust effect or makes it impossible to exhaust. After many creative experiments, it was found that when the length of the spike 21 is 10mm-17mm and the diameter is 0.5mm-1.5mm, the puncture effect is best and the stability is high.

[0032] Further, see Figure 1-2 The composite material rolling device also includes a positioning assembly 6, which is fixedly mounted on the mounting frame of the barbed shaft 2, and the barbed shaft 2 is rotatably mounted on the positioning assembly 6. The positioning assembly 6 is used to adjust the distance between the two barbed shafts 2. By adding the positioning assembly 6 to adjust the distance between the two barbed shafts 2, the loading and unloading of the composite material 5 to be rolled can be facilitated. In addition, the distance between the barbed shafts 2 can be adjusted to adapt to the composite material 5 to be rolled of different specifications and sizes, thereby improving the versatility of the device.

[0033] Specifically, the position adjustment component 6 includes a lifting cylinder 61, a three-position five-way electromagnetic control valve (not shown in the figure), an air source (not shown in the figure), a connecting air circuit (not shown in the figure) and a lifting frame 64. The lifting frame 64 slides up and down along the rotating frame of the thorn shaft 2. One of the two thorn shafts 2 is rotatably arranged on the lifting frame 64. The output shaft of the lifting cylinder 61 is fixedly connected to the lifting frame 64. The connecting air circuit sequentially connects the air source, the three-position five-way electromagnetic control valve and the lifting cylinder 61. The three-position five-way electromagnetic control valve controls the lifting height of the lifting cylinder 61, thereby controlling the height of the thorn shaft 2. Among them, the stroke of the lifting cylinder 61 can be controlled by the three-position five-way electromagnetic control valve, thereby controlling the height of the lifting frame 64 and the two thorn shafts 2, and then realizing the adjustment of the distance between the two thorn shafts 2, which is convenient and quick. Among them, the specific connection method between the air circuit and the lifting cylinder 61 and the three-position five-way electromagnetic control valve is the existing technology, which will not be repeated here. In this embodiment, a guide rail 62 is vertically arranged on the rotating frame of the thorn shaft 2, and the lifting frame 64 is slidably arranged on the guide rail 62 through a slider 63, which can further improve the stability of the adjustment. In other embodiments, the adjustment component can also use a motor screw assembly to adjust the lifting frame 64, which can also achieve the effect of adjustment.

[0034] In this embodiment, the two roller shafts 4 can also use a structure similar to the thorn shaft adjustment to adjust the distance between them, thereby improving the convenience of loading.

[0035] Further, see Figure 1-2, the first transmission gear 71 and the second transmission gear 72 are respectively provided at one end of the two thorn shafts 2 located at the top and the bottom, and the first transmission gear 71 and the second transmission gear 72 can mesh with each other, and the first transmission gear 71 and the second transmission gear 72 have the same number of teeth. In this embodiment, the thorn shaft 2 will continuously rotate when puncturing and exhausting the composite material 5 to be rolled. When the rotation speeds of the two thorn shafts 2 are different, a speed difference will be formed, and then the spikes 21 on the two thorn shafts 2 will pull the composite material 5 to be rolled, and then damage the composite material 5 to be rolled. In this embodiment, by respectively providing the first transmission gear 71 and the second transmission gear 72 meshing with each other at one end of the two thorn shafts 2, and the first transmission gear 71 and the second transmission gear 72 have the same number of teeth, it can ensure that the movement speed of the spikes 21 on the two thorn shafts 2 is the same, and then the processing effect is guaranteed.

[0036] Further, see Figure 1-2 The composite material rolling device further comprises a servo motor 73 arranged at one end of the thorn shaft 2, and a driving gear is arranged at the end of the output shaft of the servo motor 73, and the driving gear is meshed with the second transmission gear 72. By adding the servo motor 73, the rotation speed of the two thorn shafts 2 can be controlled, and the movement speed of the spikes 21 on the thorn shaft 2 can be made the same as the movement of the composite material 5 to be rolled, which can effectively reduce the lateral interaction force between the spikes 21 and the composite material 5 to be rolled, prevent the spikes 21 from pulling against the composite material 5 to be rolled, and damage the composite material 5 to be rolled, thereby ensuring the processing effect. In this embodiment, the thorn shaft 2 located at the top is rotatably arranged on the lifting frame 64 through a bearing, and the thorn shaft 2 located at the bottom is rotatably arranged on the thorn shaft 2 mounting frame through a bearing. The same servo motor 73 is fixedly installed on the thorn shaft 2 mounting frame and is transmission-connected with the thorn shaft 2 below, so the structure is simpler and the production cost can be effectively controlled.

[0037] This embodiment also provides a carbon fiber cloth production line, including any composite material rolling device as described above.

[0038] Among them, the composite material rolling device arranges a thorn shaft 2 on the path of the composite material 5 to be rolled, so that the bubbles on the composite material 5 to be rolled can be punctured by the thorn shaft 2, and then the composite material 5 to be rolled is rolled by the rolling shaft 4, so that bubbles can be eliminated while completing the rolling process, thereby ensuring the processing quality.

[0039] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
