Description

Technical Field

[0001] This invention belongs to the technical field of fiberglass board equipment, specifically, it relates to equipment for fiberglass board production. Background Technology

[0002] The production process of fiberglass board involves mixing fiberglass with polypropylene, opening the mixture, combing it with a carding machine, laying the web with a web laying machine, needle punching it with a needle punching machine, winding up the semi-finished felt, pressing it into shape with a flat hot press (mixed with resin), and cutting it into fiberglass board.

[0003] The most crucial step in the production of the aforementioned fiberglass board is the piercing process using a needle punching machine. This piercing process involves repeatedly moving the needles up and down, causing the fiber filaments to move up and down and intertwine with each other, thereby increasing the strength of the fiberglass board.

[0004] However, fiberglass boards manufactured by weaving fibers together through needle punching still have some shortcomings in strength. Therefore, we propose a piece of equipment for fiberglass board production. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a device for producing fiberglass boards that can overcome or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a device for producing fiberglass board, including a workbench, and further comprising: a plurality of first nozzles disposed on the surface of the workbench, the first nozzles being used to spray fiber cloth on the board surface in the weft direction; a plurality of second nozzles disposed on the surface of the workbench, the second nozzles being used to continuously spray fiber cloth on the board surface in the longitude direction; a pressure plate disposed on the side of the second nozzles away from the first nozzles, the pressure plate having a plurality of rows of pressure teeth on the side of the pressure plate near the upper surface of the fiber cloth, the same number as the number of first nozzles, the pressure teeth having protruding pressure strips for pressing the spray areas of the second nozzles, so that the spray areas of the second nozzles and the spray areas of the first nozzles are alternately pressed together.

[0007] Preferably, a first mounting bracket and a second mounting bracket are fixedly connected to the surface of the workbench, and the first nozzle and the second nozzle are respectively mounted on the first mounting bracket and the second mounting bracket.

[0008] Preferably, a third mounting bracket is fixedly connected to the surface of the workbench, a driving device is mounted on the third mounting bracket, the pressure plate is connected to the driving device, and the driving device is used to drive the pressure plate to move up and down reciprocally.

[0009] Furthermore, it also includes multiple overflow channels located between two adjacent overflow channels, which are used to prevent the material ejected from the first nozzle from flowing to both sides.

[0010] Preferably, the plurality of anti-overflow plates are connected by scraper plates to scrape the material sprayed from the first nozzle.

[0011] Preferably, the scraper is connected to the first mounting bracket via a connecting arm.

[0012] Preferably, the pressure strip includes a long strip located on the central axis of the pressure teeth.

[0013] Preferably, the pressure strip includes symmetrically arranged figure-eight strips, and the figure-eight strips on two adjacent pressure teeth are rhomboid in shape.

[0014] Preferably, the pressure strip comprises three symmetrically arranged inclined strips, and the inclined directions of the three inclined strips on two adjacent pressure teeth are the same.

[0015] A fiberglass board manufacturing process mainly includes the following steps:

[0016] S1. Pass the fiber cloth through the first nozzle, the second nozzle, and the pressure plate in sequence, and spray a continuous length of weft glue through the first nozzle on the open area of ​​the fiber cloth.

[0017] S2. The second nozzle sprays glue continuously between adjacent weft glue outlets, resulting in warp glue outlets between adjacent weft glue outlets. Through the cooperation of the first nozzle and the second nozzle, a woven warp and weft shape is formed on the fiber cloth.

[0018] S3. Press the fiber cloth down with the pressure plate to press the warp and weft glue outlets together, forming an uneven surface in the pressed area and creating multiple sides, thus completing the weaving of the fiber cloth.

[0019] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0020] 1. Compared with existing technologies, the equipment used for producing fiberglass boards does not require needle punching of the fiber cloth. Instead, it sprays resin adhesive onto the fiber cloth and weaves the resin adhesive onto the fiber cloth in a warp and weft manner, thereby improving the strength of the fiber cloth and thus the strength of the fiberglass board. Therefore, it can save manufacturing costs compared with needle punching equipment.

[0021] 2. The equipment used for producing fiberglass boards uses a first nozzle to spray material onto the open spaces, creating a continuous weft-shaped adhesive distribution on the fiber cloth. A second nozzle sprays material continuously between adjacent weft-shaped adhesive distributions, creating warp-shaped adhesive distributions. The combined action of the first and second nozzles forms a woven warp and weft pattern on the fiber cloth. After the first and second nozzles have finished spraying, the fiber cloth passes through a pressure plate. The pressure plate presses down on the fiber cloth, and the pressure teeth and strips on the pressure plate press the warp and weft adhesive distributions together, resulting in a stronger bond between the woven warp and weft adhesive distributions, thus improving the strength of the fiberglass board.

[0022] 3. The equipment used for producing this fiberglass board presses together the warp and weft adhesives using long strips, creating an uneven surface at the press. This facilitates the bonding of the warp and weft adhesives, resulting in a strong woven structure on the fiber cloth and improving the strength of the fiberglass board.

[0023] 4. The equipment used for producing this fiberglass board uses a herringbone strip to press the warp and weft adhesive together, creating an uneven surface at the pressed joint. This facilitates the bonding of the warp and weft adhesives, resulting in a strong woven pattern on the fiber cloth and improving the strength of the fiberglass board. Simultaneously, the herringbone strips on the two pressing teeth are diamond-shaped, further enhancing the strength of the pressed joint and creating multiple side edges.

[0024] 5. The equipment used for producing fiberglass boards uses three inclined lines to press the warp and weft adhesive together, creating an uneven surface at the pressed joint. This improves the bonding between the warp and weft adhesives, resulting in a strong woven pattern on the fiber cloth and enhancing the strength of the fiberglass board. Furthermore, the three inclined lines further increase the strength of the pressed joint and create multiple sides at the pressed joint. Attached Figure Description

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] When this device is in use, the fiber cloth 12 passes through the first nozzle 21, the second nozzle 31, and the pressure plate 42 in sequence.

[0041] The fiber cloth 12 itself is also woven from multiple weft threads 121 and warp threads 122, with gaps 123 formed between the weft threads 121 and warp threads 122. When the first nozzle 21 sprays out the material, it will cover the gaps 123.

[0043] After the first nozzle 21 and the second nozzle 31 have finished spraying, when passing through the pressure plate 42, the pressure plate 42 presses down on the fiber cloth 12. Through the cooperation of the pressure teeth 5 and the pressure strip 50 on the pressure plate 42, the warp glue 61 and the weft glue 6 are pressed together, making the bond between the woven warp glue 61 and the weft glue 6 stronger, which in turn helps to improve the strength of the fiberglass board.
