Description

Technical Field

[0001] The utility model relates to the field of carbon fiber production, in particular to a prepreg tape hot-melt overlapping device. Background Art

[0002] As we all know, thermosetting prepreg tapes are widely used in the field of carbon fiber molding. At present, thermosetting prepreg tapes can be used in winding, manual laying and wide band winding processes. Due to the limited storage of thermosetting prepreg tapes, the overlap between the two reels during the material change process is particularly important. At present, the two rolls of material are overlapped in a traditional way, and the overlap quality and overlap strength are not high, which reduces the winding strength of the two rolls of material, also reduces the overlap efficiency, and affects the production time. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a prepreg hot melt lap joint device to solve the problem that the lap joint quality and lap joint strength between two rolls of material at the current stage are not high, thereby reducing the winding strength of the two rolls of material, reducing the lap joint efficiency and affecting the production time.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a prepreg tape hot-melt lap joint device, provided with a base plate, characterized in that a support is fixed on the upper left side of the base plate, a heating plate is installed at the center position of the upper side of the base plate, two screws are fixed in parallel at the right end of the base plate, springs are sleeved on the screws, hanging plates are inserted at the upper ends of the two screws, adjusting nuts are screwed on the upper parts of the screws, the hanging plates are limited between the adjusting nuts and the upper ends of the springs, the hanging plates can slide up and down along the screws, a pressing plate is hinged on the support through a pin shaft, elastic temperature-resistant cotton is installed at the lower part of the pressing plate, a handle is fixed on the upper side of the right end of the pressing plate, and a hook is hinged at the lower right end of the pressing plate.

[0005] The beneficial effect of the utility model is that by operating the pressing plate in conjunction with the heating plate, the hanging plate and the elastic heat-resistant cotton for hot pressing, stable bonding is ensured, and the use of the elastic heat-resistant cotton can make the prepreg tapes fit more closely, increase the winding strength, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0009] In the figure, 1. base plate, 2. support, 3. pressure plate, 4. handle, 5. hanging plate, 6. hook, 7. spring, 8. heating plate, 9. prepreg tape, 10. elastic temperature-resistant cotton. DETAILED DESCRIPTION

[0010] like Figure 1 and Figure 2 , provided with a base plate 1, a support 2 is fixed on the upper left side of the base plate 1, a heating plate 8 is installed at the center position of the upper side of the base plate 1, two screws are fixed in parallel on the right end of the base plate 1, a spring 7 is mounted on the screw, a hanging plate 5 is inserted on the upper ends of the two screws, an adjusting nut is screwed on the upper part of the screw, the hanging plate 5 is limited between the adjusting nut and the upper end of the spring 7, the hanging plate 5 can slide up and down along the screw, a pressing plate 3 is hinged on the support 2 through a pin shaft, an elastic temperature-resistant cotton 10 is installed at the lower part of the pressing plate 3, a handle 4 is fixed on the upper right end of the pressing plate 3, and a hook 6 is hinged at the lower right end of the pressing plate 3.

[0011] When the utility model is used, when two prepreg tapes 9 need to be fused and overlapped, the pressing plate 3 is lifted by the handle 4, and the two prepreg tapes 9 to be overlapped are placed on the heating plate 8. The heating plate 8 forms a closed-loop temperature control through the internal heating tube and the temperature sensor to ensure that the temperature control accuracy is ±2°C. The distance between the hanging plate 5 and the bottom of the hook 6 is adjusted by turning the adjustment nut to ensure that the crimping force is appropriate. The pressing plate 3 is dropped by the handle 4, and the slope on the hook 6 is hung together along the guide position on the hanging plate 5 to maintain a constant pressing force. The elastic heat-resistant cotton 10 on the pressing plate 3 has good toughness and deforms under pressure. After the pressure is removed, the deformation is restored to the original shape.
