Description

Technical Field

[0001] This invention relates to the field of composite material production technology, and more specifically, to a honeycomb core fiberglass composite production line based on a sandwich structure. Background Technology

[0002] In the automotive interior parts manufacturing industry, sandwich-structured fiberglass composite materials with a honeycomb core are widely used in components such as automotive headliners. However, traditional composite production lines are mostly semi-automated, resulting in problems such as fragmented processes, poor bonding accuracy, and insufficient interlayer bonding strength. This not only leads to low production efficiency but also makes the products prone to delamination and separation under complex automotive conditions, affecting structural stability and service life, resulting in unsatisfactory overall performance. Therefore, this invention proposes a honeycomb core fiberglass composite production line based on a sandwich structure. Summary of the Invention

The traction mechanism includes a traction frame with a conveying channel running through it. An active traction roller is provided above or below the conveying channel. A power assembly for controlling rotation is connected to the active traction roller.

However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1 See Figures 1 to 4 As shown, the honeycomb core fiberglass composite production line based on a sandwich structure involved in this embodiment includes, from back to front, a paper core placement table 100, a paper core stretching machine 200, a first fiberglass roll unloading mechanism 300, a second fiberglass roll unloading mechanism 400, a traction mechanism 500, a stapled mechanism 600, and a shearing mechanism 700. The paper core placement platform 100 is located at the end of the paper core stretching machine 200 near the feed port; The first fiberglass roll feeding mechanism 300 is located above the discharge port of the paper core stretching machine 200, and the second fiberglass roll feeding mechanism 400 is located below the discharge port of the paper core stretching machine 200. The traction mechanism 500 includes a traction frame 501, on which a conveying channel 502 runs through the front and rear. Below the conveying channel 502, an active traction roller 503 is provided. The active traction roller 503 is connected to a power assembly for controlling rotation. The power assembly includes a motor 504 mounted on the traction frame. Above the conveying channel 502, a driven traction roller 505 is provided to match the active traction roller. Both the driven traction roller 505 and the active traction roller 503 are rotatably connected to the traction frame 501. The nailing mechanism 600 includes a nailing frame 601, and electric nailing machines 602 are respectively provided on the left and right sides of the nailing frame 601. The shearing mechanism 700 includes a shearing frame 701, a pressure-bearing platform 702 on the shearing frame 701, a downward-facing cutting blade 703 above the pressure-bearing platform 702, and a linear reciprocating motion mechanism for controlling the up-and-down movement of the cutting blade 703. The linear reciprocating motion mechanism includes a pneumatic push rod 704 mounted on the shearing frame.

[0017] Furthermore, a third fiberglass roll unloading mechanism 800 is provided above the discharge port of the paper core stretching machine 200.

[0018] Furthermore, the first fiberglass roll feeding mechanism 300, the second fiberglass roll feeding mechanism 400 and the third fiberglass roll feeding mechanism 800 each include a feeding frame, a feeding roller and a tension adjustment mechanism (not shown). The feeding frame is fixed to the paper core stretching machine, and the feeding roller is rotatably connected to the feeding frame.

[0019] Furthermore, the paper core stretching machine 200 includes a honeycomb paper core stretching dryer.

[0020] The specific implementation process of this sandwich-structured honeycomb fiberglass composite production line is as follows: Unstretched and dried honeycomb paper cores are placed on the paper core placement table 100. The paper cores are conveyed into the paper core stretching machine 200 (honeycomb paper core stretching and drying machine) to complete stretching, shaping, and drying. The dried honeycomb paper cores are discharged from the paper core stretching machine 200. At this time, the first fiberglass roll unwinding mechanism 300, the second fiberglass roll unwinding mechanism 400, and the third fiberglass roll unwinding mechanism 800 simultaneously unwind. The fiberglass tension is controlled by the tension adjustment mechanism, and the fiberglass is respectively bonded to the upper end face, lower end face, and designated area of ​​the upper end face of the honeycomb paper core to form a sandwich-structured composite blank. The composite blank enters the conveying channel 502 of the traction mechanism 500. The motor 504 drives the active traction roller 503 to rotate, driving the driven traction roller 505 to rotate synchronously. Stable conveying of the composite blank is achieved through roller clamping. The composite blank is conveyed to the stapled mechanism 600, and the stapled frame 601... The electric nailing machines 602 on both sides operate synchronously to mechanically nail the fiberglass layer and the honeycomb paper core to achieve interlayer fixation. The composite blank after nailing is continued to be conveyed to the shearing mechanism 700. The pneumatic push rod 704 drives the cutter 703 to move downward, and cooperates with the pressure platform 702 to cut the composite blank to a fixed length to obtain the intermediate product of honeycomb paper core fiberglass composite.

[0021] The present invention relates to a sandwich-structure-based honeycomb fiberglass composite production line. This production line adopts integrated continuous operation, reducing manual intervention and equipment transfer. Synchronous traction and symmetrical nailing design ensure the bonding accuracy of the fiberglass layers and the honeycomb core, effectively improving production efficiency and product quality stability. Furthermore, mechanical nailing replaces traditional adhesive fixing, significantly improving interlayer bonding strength and weather resistance. It can handle complex working conditions and reduce the risk of delamination. Moreover, it eliminates the need to wait for adhesive curing, further shortening the production cycle and adapting to the needs of large-scale mass production. The overall functionality is comprehensive and highly practical.
