Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature composite, and more specifically, to a high-temperature composite device for glass fiber felt. Background Art

[0002] Glass fiber mat is a thin sheet product made of continuous strands or chopped strands bonded together by chemical binders or mechanical action. During processing and production, glass fiber mat and composite materials need to be pressed together to form a composite mat. In this process, the use of composite materials is the key to ensure that the layers of glass fiber mat are tightly bonded.

[0003] However, in the prior art, the placement of composite materials has become a prominent problem. Composite materials mainly exist in the form of granules or blocks, and their uniform placement on the glass fiber mat is crucial to the composite effect. Since the composite materials are granules or blocks, it is difficult to ensure that they are evenly distributed on the glass fiber mat when placed. This may lead to too much composite materials in some areas, causing material waste and increasing production costs. Uneven placement of composite materials will also lead to too little composite materials on the glass fiber mat in some areas, resulting in poor composite effects in these areas. Too little composite materials will prevent the layers of the glass fiber mat from being tightly combined, affecting the overall performance and service life of the product.

[0004] In order to solve the problem of uneven placement of composite materials, some manufacturers try to use robotic arms or automated equipment to place composite materials. However, these solutions still have certain limitations in practical applications. Although robotic arms and automated equipment can improve the accuracy of composite material placement, their adaptability needs to be improved when facing glass fiber mats of different shapes and sizes. At the same time, the introduction of highly automated equipment will increase production costs, which may be a burden for small and medium-sized enterprises.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a high-temperature composite device for glass fiber mat. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a high-temperature composite device for glass fiber mat.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a high temperature composite device for glass fiber mat, comprising:

[0008] A composite box, wherein a cavity is provided in the composite box, a conveyor belt is installed in the cavity, and the conveyor belt is used to transport the glass fiber mat;

[0009] A material spreading box, an infrared heater and a pressure roller are sequentially installed at positions corresponding to the conveyor belt in the cavity;

[0010] A storage box is slidably connected inside the material laying box, and a feed inlet communicating with the storage box is formed on the surface of the composite box. A plurality of flow grooves B are formed on one side of the storage box close to the conveyor belt, and a plurality of flow grooves A are formed on the material laying box at positions corresponding to the plurality of flow grooves B. One side of the storage box where the plurality of flow grooves B are formed is attached to one side of the material laying box where the plurality of flow grooves A are formed, and a telescopic device is installed on the material laying box. The telescopic end of the telescopic device is connected to the storage box, and the telescopic device is used to drive the storage box to move inside the material laying box, so as to control the intersection or coincidence of the plurality of flow grooves A and the flow grooves B.

[0011] Preferably, a scraper is installed between the infrared heater and the pressure roller inside the cavity.

[0012] The scraper can scrape off the melted composite material, reducing the problem of waste of composite material caused by the accumulation of composite material at one place on the glass fiber mat.

[0013] Preferably, a shielding belt is arranged between the storage box and the feed inlet, and the shielding belt is used to connect the feed inlet and the storage box together.

[0014] It can make the composite material entering from the feed inlet fall into the storage box.

[0015] Preferably, a controller is installed on the composite box, and the controller is connected to the telescopic device. The controller is used to control the working state of the telescopic device.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. In the utility model, through the storage box communicated with the feed inlet, the placed composite material can be loaded. At the same time, driven by the telescopic device, the storage box will move inside the material laying box. As the storage box moves, the flow grooves B and the flow grooves A will have a short-term coincidence. At the moment when the flow grooves B and the flow grooves A coincide, the composite material in the storage box will fall onto the surface of the glass fiber mat on the lower conveyor belt. Driven by the telescopic device to regularly drive the storage box to move, the composite material can be evenly fallen onto the glass fiber mat under a simple mechanical mechanism, thus solving the problems of uneven feeding of the composite material, easy waste of the composite material or affecting the composite effect existing at present.

[0024] As Figures 1-4 shown, the present utility model provides a high-temperature composite device for glass fiber mats, including a composite box 1. A cavity 9 is provided in the composite box 1, and a conveyor belt 2 is installed in the cavity 9 for transporting glass fiber mats;

[0025] A material spreading box 3, an infrared heater 4, and a pressing roller 6 are sequentially installed in the cavity 9 corresponding to the position of the conveyor belt 2;

[0026] The infrared heater 4 is used to heat the composite material on the glass fiber mat, which belongs to the prior art and will not be elaborated here;

[0027] The pressing roller 6 is used to compact between the composite material melted on the surface of the glass fiber mat and the glass fiber mat, and extrude the internal air to avoid affecting the composite effect;

[0028] A storage box 8 is slidably connected in the material spreading box 3, and a feed inlet 7 communicating with the storage box 8 is provided on the surface of the composite box 1. A plurality of flow channels B81 are provided on the side of the storage box 8 close to the conveyor belt 2. A plurality of flow channels A31 are provided on the material spreading box 3 corresponding to the plurality of flow channels B81. The side of the storage box 8 provided with the plurality of flow channels B81 is attached to the side of the material spreading box 3 provided with the plurality of flow channels A31, and an expander 10 is installed on the material spreading box 3. The telescopic end of the expander 10 is connected to the storage box 8. The expander 10 is used to drive the storage box 8 to move in the material spreading box 3 to control the intersection or overlap of the plurality of flow channels A31 and the flow channels B81;

[0029] In summary, compared with the existing problem of uneven feeding of composite materials, which easily leads to waste of composite materials or affects the composite effect, the present invention can load the composite materials placed in it through the storage box 8 connected to the feed port 7, and at the same time, driven by the telescopic device 10, the storage box 8 will move in the material laying box 3. As the storage box 8 moves, the flow slot B81 and the flow slot A31 will overlap briefly. At the moment when the flow slot B81 overlaps with the flow slot A31, the composite materials in the storage box 8 fall onto the surface of the glass fiber felt on the conveyor belt 2 below. When the telescopic device 10 regularly drives the storage box 8 to move, the composite materials can be evenly dropped onto the glass fiber felt under a simple mechanical mechanism.

[0030] At the same time, combined with the Internet of Things technology, a controller 12 can be installed on the composite box 1, and the controller 12 is connected to the expander 10. The controller 12 is used to control the working state of the expander 10, and then the controller 12 can be adjusted by the host to control the operating speed of the expander 10, so as to control the delivery of the composite material, which is convenient for adjustment according to different situations and has flexibility;

[0031] It is worth noting that a scraper 5 is installed between the infrared heater 4 and the pressure roller 6 in the cavity 9. The scraper 5 can scrape off the heated and melted composite material, and can scrape off the surface of the glass fiber mat, and push the excess composite material on the surface of the glass fiber mat backward, so as to reduce the problem of composite material being accumulated in one place of the glass fiber mat and causing the waste of composite material, and make the composite material be laid more evenly on the surface of the glass fiber mat;

[0032] A shielding belt 11 is provided between the material storage box 8 and the feed port 7, and the shielding belt 11 is used to connect the feed port 7 and the material storage box 8 together, so that the composite material entering from the feed port 7 can fall into the material storage box 8;

[0033] The glass fiber felt is transported from the conveyor belt 2 to the compound box 1. When passing through the material laying box 3, the composite material in the storage box 8 will fall from the channel temporarily formed by the flow groove B81 and the flow groove A31 onto the glass fiber felt below as the telescopic device 10 moves. Then, it is heated by the infrared heater 4 to melt the composite material on the glass fiber felt. Under the movement of the scraper 5, the excess composite material is scraped off and mixed with the glass fiber felt at the rear. Then, it is compacted by the pressing roller 6 to complete the preliminary compounding of the glass fiber felt.
