Description

Technical Field

[0001] The utility model belongs to the technical field of weaving equipment and relates to a composite material forming device. Background Art

[0002] With the development of the daily-use ceramic industry, a new type of permeable composite material mold has replaced the original gypsum mold production, among which glass fiber is widely used due to its excellent performance. The traditional method is to put the twisted glass fiber bundles into a laminating mold and laminate them into pieces of molded solid materials for the subsequent production of permeable molds. However, the glass fiber bundles need to be arranged layer by layer in the laminating mold, and the adjacent layers need to be crossed at 90 degrees. The operation process is relatively cumbersome, and the laminated molded solid materials cannot be continuously molded and output when large-scale production is required, which is inefficient.

[0003] To solve the above problems, there is a device that can continuously shape composite materials into solid materials, including a weaving mechanism with a core mold and a spindle. The spindle weaves the glass fiber bundle and then rolls it up, and finally puts it into an oven to form a solid material for later mold production. Although this solution can continuously shape composite materials such as glass fibers into solid materials, the glass fiber bundles are easily dispersed or shifted during the weaving process, resulting in a loose braid. The strength and consistency of the braid after molding are low, making it impossible to guarantee the product quality during the later mold production. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and propose a composite material forming device. The technical problem to be solved by the utility model is: how to improve the structural consistency in the production process of composite forming solid materials.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] A composite material forming device includes a weaving mechanism capable of weaving glass fibers into shape, the weaving mechanism includes a plurality of spindles and a columnar core mold, the plurality of spindles are spaced apart at the front end of the core mold, and the device is characterized in that a glue spraying cylinder with an opening facing downward is provided above a position close to the rear end of the core mold, and a pressure wheel group and a rotatable winding disk are provided in sequence on the rear side of the core mold.

[0007] Each spindle is loaded with a glass fiber bundle, which is wound around the core mold by the spindle so that several glass fiber bundles are cross-woven together to form a glass fiber tube, and then the woven glass fiber tube is treated with glue by a glue spraying cylinder, and a thinner glue is formed on the surface of the glass fiber tube, and then the glass fiber tube is flattened by a pressing wheel group to turn it into a glass fiber tape. In the process of forming the glass fiber tape, the pressing wheel group can squeeze out excess glue and can better bond several glass fiber bundles more firmly. Finally, the winding disk is used to wind up the woven glass fiber tape. During the operation of the device, the spindle and the winding disk can provide a certain tension to the glass fiber bundle, so that the glass fiber can be continuously formed in the process of being formed into a solid material and the woven glass fiber bundle can be wound on the winding disk. After the winding disk is full, the winding disk is placed in an oven for heating and curing. After forming, it can be cut into solid materials of different sizes as required for the production of permeable molds. Firstly, by setting up the glue spraying cylinder, the adhesion between the glass fiber bundles wound on the core mold and interwoven with each other can be increased, so that the woven glass fiber bundles can play a certain positioning role and reduce the displacement of the glass fiber bundles; secondly, the woven glass fiber tube is flattened by the pressing wheel group, so that the glass fiber bundles are closer together, the adhesion of the glue to them is improved, the displacement of the glass fiber bundles is further reduced, and the structural consistency in the production process of the composite molded solid material is improved; finally, the woven glass fiber tube is pressed into a glass fiber belt, which can greatly reduce the winding amount of the winding reel to reduce the replacement speed of the winding reel, and greatly improve the production efficiency.

[0008] In the above-mentioned composite material forming device, the pressing wheel group includes two pressing wheels arranged in parallel up and down, the core mold is cylindrical, the distance between the two pressing wheels is smaller than the diameter of the core mold, the two pressing wheels are perpendicular to the core mold, and the two pressing wheels are close to the rear end of the core mold. The distance between the two pressing wheels is smaller than the diameter of the core mold, and the woven glass fiber tube can be pressed into a glass fiber tape using a simple structure, with a simple structure and low cost. The two pressing wheels are close to the rear end of the core mold, which has an efficient molding process, so that the glass fiber tube can be pressed into a glass fiber tape as soon as possible to avoid the glue from starting to harden.

[0009] In the composite material forming device described above, the device further comprises a base, a vertically arranged support rod is fixed on the base, and the two pressing wheels are connected to the support rod. The simple and concise structure ensures the stability of the pressing wheel connection, facilitates operation and maintenance, and has high reliability.

[0010] In the composite material forming device described above, a glue receiving box is provided below the rear end of the core mold, and the glue receiving box is provided on the base. The setting of the glue receiving box can receive the excess glue sprayed by the glue spraying cylinder on the core mold, thereby avoiding the waste of glue and facilitating secondary use.

Excess glue can flow back to the glue connection box through the glue delivery pipe and be transported back to the glue spraying cylinder for secondary use. A closed reflux circulation system is formed between the glue connection box, the glue spraying cylinder and the glue delivery pipe, thereby reducing the operation steps.

[0012] In the composite material forming device described above, the support rod is connected to a support frame arranged in the direction of the winding drum, and the support frame is connected to a guide wheel, and the guide wheel is located between the pressure wheel and the winding drum. The setting of the guide wheel helps guide the glass fiber tape, so that the glass fiber tape can be wound on the winding drum in the correct direction and path, and at the same time, it can provide certain support for the glass fiber tape.

[0013] In the above composite material forming device, the braiding mechanism further comprises a support seat, a plate-shaped support disc is connected to the support seat, the core mold and the plurality of spindles are arranged on the end surface of one end of the support disc and are perpendicular to the end surface of the support disc. The support disc is used to connect the core mold and the spindles and provide better support.

[0014] In the composite material forming device described above, the device further comprises a movable seat with rollers at the bottom, and the winding disc is rotatably connected to the movable seat. The arrangement of the rollers facilitates the movement of the winding disc, thereby improving the flexibility and portability of the movement of the winding disc.
