Description

Technical Field

[0001] The invention relates to the technical field of winding machinery, and in particular to an online switching device and method for a substrate specially used for enhanced manufacturing. Background Art

[0002] Continuous fiber reinforced composite 3D printing substrate refers to a substrate that is pre-impregnated with continuous fibers and thermoplastic resin. This material is mainly used in composite printing technology and is a new type of composite printing substrate. The cross-section of the substrate is circular. Compared with traditional printing substrates, it has excellent strength and modulus. It is an ideal new structural material that can be quickly formed. However, due to its high modulus, the rebound force / internal stress in the winding process is large, which brings great difficulties to the winding of the substrate. At present, the existing equipment mainly uses the traditional printing resin substrate winding device. This device has poor continuity in the winding process of the fiber-reinforced 3D printing substrate, which is mainly manifested in the substrate being easily damaged during the winding process and the wound substrate slipping and spreading.

[0003] In addition, the existing 3D printing substrate is generally wound in a coil winding method, but the conventional winding coils on the market cannot meet the winding conditions of continuous fiber substrates, which brings difficulties to industrial production. The present invention improves the conventional coil and uses a winding online fixing / switching device to solve this problem. Summary of the invention

[0004] The purpose of the present invention is to provide an online rapid fixing / switching device for continuous fiber reinforced composite material 3D printing substrate, which is mainly aimed at the winding of high modulus continuous fiber composite material printing substrate.

[0005] The innovative concept of the present invention is based on the fact that the fiber-reinforced printing substrate has a relatively high modulus, which results in a relatively large internal stress during the winding process, making it difficult to wind the substrate. If the substrate breaks, it can be quickly replaced with a spare reel online.

[0006] The invention is innovative in that it is composed of a clampable, continuously rotating component (1), a winding reel (2) and an online fast fixing / switching component (3). The continuously rotating component (1) is an inflatable shaft, which is driven by a motor to achieve continuous rotation. The continuous fiber-specific winding reel (2) is used synchronously with the online fast fixing / switching component (3) by improving the conventional winding reel structure.

[0007] The further winding reel (2) is composed of two sets of side plates (2-1) and an inner cylinder (2-2). The outer surface of the inner cylinder (2-2) is provided with a plurality of inclined holes (2-3) with an inclined outer section angle of 55 degrees, which can avoid the phenomenon of the base material breaking during the winding process.

[0008] Further online quick fixing / switching component (3): composed of a housing (3-1), a spring (3-2), a rubber sleeve (3-3) and a pressing column (3-4). The housing (3-1) is provided with a clamping groove (3-5) 3 mm away from the edge, and the setting range is one circle in the outer diameter direction, so that the printing wire can enter the clamping groove at multiple angles. The clamping sleeve (3-3) is characterized in that the material of the part is rubber. When used synchronously with the spring (3-2), controlling the rebound force of the spring (3-2) can clamp the printing wire and protect it at the same time.

[0009] The beneficial effects of the present invention are:

[0010] The present invention designs an online fast fixing / switching device, which can use the spring force to clamp the substrate by pressing the elastic column. If the assembled 3D printing substrate dedicated winding reel encounters a substrate breakage, it can be quickly replaced with a spare reel online, greatly improving the winding efficiency and saving material costs. The clamping sleeve device is made of a buffer rubber pad, which can not only control the spring rebound force, but also play a protective role in preventing the printing wire from being broken while clamping it.

[0011] The outer surface of the inner cylinder of the substrate-specific winding reel of the present invention is provided with several inclined outer circles, which is mainly aimed at the problem that the modulus of the continuous fiber-reinforced composite printing wire is high, resulting in difficulty in winding, and the substrate ends need to be fixed and cannot be bent. The angle of the section between the inclined hole and the outer circle of the inner cylinder is set to 55 degrees. After the substrate passes through the inclined hole, its bending angle can be reduced. The small resilience of the substrate avoids the phenomenon of substrate breakage during the winding process, improves processability and reduces overall cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Specific operation method;

[0018] In order to make the technical means and innovative features of the present invention easy to understand and achieve the purpose and effect, the present invention is further explained below in conjunction with specific implementation methods.

[0019] The present invention provides an online switching device and method for a special substrate for enhanced manufacturing. It includes a clampable and continuously rotating component (1), a winding reel (2) and an online fast fixing / switching component (3). During the winding process, the end of the substrate passes through the inner fine hole of the winding reel (2), and the printing substrate is placed in the clamping groove (3-5) by manually pressing the elastic column (3-4), and then the component (3-3) is released, and the printing substrate is clamped by the rebound force of the spring (3-2), so that the substrate can be fixed. Then, the clampable and continuously rotating component (1) is ventilated to clamp the winding reel (2), and when the motor driving component (1) is started to rotate, the winding reel performs a rotary motion to achieve the winding of the printing substrate. This type of operation can also be applied to online substrate replacement winding reels.
