[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please see Figure 1-4 A blanking device for sandwich composite panel extrusion production includes a blanking frame 1, on which two sets of traction mechanisms are arranged left and right, and a cutting mechanism is arranged between the two sets of traction mechanisms. It also includes a flattening conveying mechanism that passes through the middle of the traction mechanisms from the bottom. The traction mechanism includes upper traction rollers 3 and lower traction rollers 2 arranged vertically. The flattening conveying mechanism includes two sets of chains 8 arranged on the front and rear sides. Multiple sets of support bars 9 that pass around one of the lower traction rollers 2 of the traction mechanism are arranged between the two sets of chains 8. It also includes a lifting drive mechanism for driving the two upper traction rollers 3 located on the upper side to rise and fall, a traction drive mechanism for driving the two upper traction rollers 3 to rotate simultaneously, and a flattening conveying drive mechanism for driving the two sets of chains 8 to rotate simultaneously.

[0022] Specifically, the lifting drive mechanism includes a lifting drive cylinder 14 that is vertically fixedly installed at the top of the unloading frame 1. The bottom output end of the lifting drive cylinder 14 is fixedly installed with a lifting slide 13 that slides and guides the unloading frame 1. Two upper traction rollers 3 are rotatably connected to the lifting slide 13. The traction drive mechanism is fixedly installed on the lifting slide 13. Through the lifting drive cylinder 14, the lifting slide 13, the traction drive mechanism, and the two sets of upper traction rollers 3 can be easily lifted as a whole.

[0023] Specifically, the traction drive mechanism includes a traction drive motor 17 fixedly mounted on the lifting slide 13. The output shaft of the traction drive motor 17 is fixedly connected to one of the upper traction rollers 3, and the two upper traction rollers 3 are connected by a transmission assembly 15. When the traction drive motor 17 is started, it is convenient to drive one of the upper traction rollers 3 to rotate. Through the transmission of the transmission assembly 15, it is convenient to drive the other upper traction roller 3 to rotate synchronously. This, in turn, cooperates with the two lower traction rollers 2 on the lower side to facilitate the traction operation of the raw material of the sandwich composite board.

[0024] Specifically, the smoothing conveying drive mechanism includes four sets of sprockets 10 for supporting the chain 8 and rotatably connected to the unloading rack 1. The sprockets 10 located on the front and rear sides are fixedly connected by couplings 11. It also includes a transmission drive motor 18 for driving one sprocket 10 to rotate. The coupling 11 on this side is connected to another set of couplings 11 through a transmission component 2 16. Starting the transmission drive motor 18 and cooperating with the transmission component 2 16 and the four sets of couplings 11 facilitates the rotation of the chains 8 on both sides, thereby driving multiple support bars 9 to rotate synchronously. While multiple support bars 9 are rotating, the cut seams of the sandwich composite board that is laid down can be smoothed and conveyed. Furthermore, the transmission component 1 15 and the transmission component 2 16 can adopt a sprocket and chain or belt and pulley transmission form, preferably a sprocket and chain transmission form.

[0025] Specifically, the cutting mechanism includes a sandwich panel guide groove 4 fixedly installed on the unloading rack 1 and located near the left side of the traction mechanism. A cutter 5 is vertically slidably arranged on the right side of the sandwich panel guide groove 4. A cutting drive cylinder 12 is vertically fixedly installed on the sandwich panel guide groove 4. A connecting frame 7 is fixedly installed on the output shaft of the cutting drive cylinder 12. The top of the cutter 5 is fixedly connected to the connecting frame 7. A cutting table 6 fixedly connected to the unloading rack 1 is located directly below the cutter 5. The cutting table 6 is located below the support bar 9 located on the upper side. When cutting, multiple support bars 9 can be rotated until the cutter 5 is in the position between two adjacent support bars 9. Then, the cutting drive cylinder 12 is activated. The connecting frame 7 drives the cutter 5 downward and cooperates with the cutting table 6 to cut the raw material of the sandwich panel.

[0026] Specifically, the unloading frame 1 is provided with a guide groove that cooperates with the vertical guide sliding of the lifting slide 13. By setting the guide groove, the overall lifting stability of the lifting slide 13 and the two sets of upper traction rollers 3 is improved.
