Description

Technical Field

[0001] This utility model belongs to the field of production equipment technology, and more specifically, it relates to a dry production equipment for composite material prepregs. Background Technology

[0002] The dry process production equipment for composite prepregs is a key piece of equipment specifically designed for manufacturing prepregs. As an important intermediate material in composite material manufacturing, prepregs are typically composed of fiber reinforcement materials and resin matrix. The dry process production equipment precisely combines fibers and resin to form semi-finished prepregs, facilitating subsequent molding and curing processes. After production, the prepregs are usually wound up using a winding device for storage and transportation.

[0003] According to application number CN201820216441.9, a dry-process prepreg production apparatus for composite materials includes a yarn feeding mechanism, a yarn spreading mechanism, an impregnation mechanism, an edge trimming mechanism, and a winding mechanism arranged sequentially along the fiber bundle transmission direction. The impregnation mechanism includes an impregnation tank, a precooling tank, and a cooling tank, which are separated by partitions and connected sequentially. The impregnation tank contains a pair of preheating rollers and a pair of high-heating rollers arranged sequentially. Nozzles are located between the preheating rollers and the high-heating rollers on both the upper and lower surfaces of the impregnation tank, arranged in two alternating rows. The precooling tank contains at least three pairs of precooling rollers, with the set temperature of the precooling rollers gradually decreasing along the fiber bundle transmission direction. The cooling tank contains a pair of cooling rollers and a pair of drafting rollers arranged along the fiber bundle transmission direction. Cooling fans are located between the cooling rollers and the drafting rollers on both the upper and lower surfaces of the cooling tank. This invention enables effective resin impregnation of fibers, resulting in high production efficiency and high-quality prepreg.

[0004] Based on the above, in the existing dry production equipment for composite prepregs, the winding equipment usually requires manual disassembly and replacement with a new winding roller after winding is completed to continue production. However, since the winding roller is heavy after winding, the labor intensity during replacement is high, which not only increases the burden on operators but also affects work efficiency. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a dry process production apparatus for composite prepregs. This addresses the issue that in existing dry process production apparatuses for composite prepregs, after winding is completed, the winding rollers typically require manual disassembly and replacement with new ones to continue production. However, the weight of the wound rollers after winding is significant, and the replacement process is labor-intensive, increasing the burden on operators and impacting work efficiency.

[0006] The purpose and effectiveness of this utility model's dry process production device for composite material prepregs are achieved through the following specific technical means:

[0007] A dry process production apparatus for composite prepreg includes a material rack, a fixed roller, a transfer frame, casters, a hinged push rod, a drive motor, a drive gear, a connecting gear, a connector, an unloading mechanism, and a transfer mechanism.

The transfer mechanism is located on the outside of the transfer frame.

[0008] Furthermore, the unloading mechanism includes: an unloading hydraulic cylinder, a fixed connecting block, a hinged connecting plate, and a winding groove; two unloading hydraulic cylinders are provided, both of which are fixedly installed on the inner side of the upper end of the material rack; two fixed connecting blocks are provided, each fixedly connected to the front end of the telescopic shaft of the two unloading hydraulic cylinders; two hinged connecting plates are provided, each hinged to the outer side of the two fixed connecting blocks; two winding grooves are provided, each opening at the front end of the two hinged connecting plates.

[0009] Furthermore, the unloading mechanism also includes: a hinge plate, a winding upper groove, a connecting torsion spring, a winding shaft, and a connecting block; two hinge plates are provided, both hinged to the upper end of the material rack; two winding upper grooves are provided, each located at the front end of one of the two hinge plates; two connecting torsion springs are provided, one end of each connecting torsion spring is fixedly connected to the inner side of the hinge plate, and the other end of each connecting torsion spring is fixedly connected to the upper end of the material rack; the winding shaft is rotatably connected to the inner sides of the winding lower groove and the winding upper groove; the connecting block is fixedly connected to the right end face of the winding shaft, and the connecting block is slidably connected to the inner side of the connecting member.

[0010] Furthermore, the transfer mechanism includes: a connecting shaft, an eccentric plate, and a connecting sliding plate; there are two connecting shafts, both of which are fixedly connected to the outside of the hinged push rod; there are two eccentric plates, each of which is fixedly connected to the outside of the two connecting shafts; there are two connecting sliding plates, both of which are slidably connected to the outside of the transfer frame, and the connecting sliding plates are slidably connected to the eccentric plates.

[0011] Furthermore, the transfer mechanism also includes: a limiting mounting groove, a sliding connecting block, and a hinged mounting component; there are two limiting mounting grooves, both of which are located on the outer side of the material rack; there are two sliding connecting blocks, each fixedly connected to the outer side of two connecting sliding plates; there are two hinged mounting components, each hinged to the outer side of the transfer frame, with a torsion spring at the hinge point between the hinged mounting component and the transfer frame, and the hinged mounting component is slidably connected to the sliding connecting block.

[0012] Furthermore, the transfer mechanism also includes: a limiting slider and a compression spring; there are two limiting sliders, both of which are slidably connected to the inner side of the upper end of the transfer frame; there are two compression springs, the upper ends of which are respectively fixedly connected to the lower end faces of the two limiting sliders, and the lower ends of which are fixedly connected to the inner side of the transfer frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention achieves automatic unloading of the wound take-up roller through the unloading mechanism. After the unloading hydraulic cylinder is activated, it pushes the hinged connecting plate to slide through the fixed connecting block. When the hinged connecting plate slides to the inclined surface at the front end of the material rack, it tilts downward, causing the take-up shaft in the under-gutter to roll onto the transfer frame. At the same time, the sliding of the fixed connecting block causes the hinged plate to lose its compression and automatically open under the action of the connecting torsion spring, requiring no manual intervention, significantly improving work efficiency and reducing labor intensity. The transfer mechanism also enables the transfer of the take-up roller. When the completed take-up shaft rolls onto the transfer frame, it will pass the limit. The slider, a limit slider, pops out under the action of a compression spring to limit the winding shaft. When the hinge push rod is pulled, the push rod drives the eccentric plate to rotate through the connecting shaft. The rotation of the eccentric plate, through its sliding engagement with the connecting sliding plate, pushes the sliding plate forward. The movement of the sliding plate, through the engagement of the sliding connecting block and the hinge mounting piece, causes the hinge mounting piece to open and disengage from the limit mounting slot, thereby allowing the transfer frame to be pulled out, completing the transfer of the winding shaft. The operation is simple and further improves work efficiency. Through the above mechanism, automatic unloading and transfer of the wound winding roller are realized without manual operation, which not only improves work efficiency but also significantly reduces labor intensity.
