[0030] The feeding section 100 includes a lower unwinding mechanism 101 for supplying the lower panel, an upper unwinding mechanism 102 for supplying the upper panel, and a filler feeding mechanism 103 for supplying filler.

The roller pressing mechanism 203 includes a plurality of rollers (not shown) arranged in two layers.

[0031] The workflow of this utility model is as follows: Metal coils are placed on the upper unwinding mechanism 102 and the lower unwinding mechanism 101 for feeding; the upper folding mechanism 202 and the lower folding mechanism 201 fold the coils, and together with the filler on the horizontal conveyor belt 1031, they are coated with adhesive by the adhesive coating device 400 and then enter between two layers of rollers 2031. After being squeezed by the two layers of rollers 2031, a three-layer sheet structure is formed; then, it is cut to a set length by the cutting section 300, thus completing the continuous production process. The roller pressing mechanism 203, the adhesive coating device 400, and other auxiliary structures are all well-known and widely used structures in the industry, and are not the innovation of this invention; therefore, they are not shown in detail.

[0032] Specifically, the upper folding mechanism 202 and the lower folding mechanism 201 adopt the following structure:

[0033] Each of the two box bodies 2013 is movably arranged on the track 2012, and a rotating shaft (not shown) is rotatably arranged on each of the box bodies 2013. A shaped roller 2014 is replaceably arranged on each of the rotating shafts. A folding motor 2015 is arranged on the folding base 2011, and the folding motor 2015 drives the rotating shafts to rotate synchronously through a folding chain 20113.

[0034] A drive gear 2016 is arranged on each of the rotating shafts, and adjacent drive gears 2016 are meshed with each other. A main gear 2017 is arranged on each of the box bodies 2013, and the main gear 2017 is meshed with at least one of the drive gears 2016. A driving rod 2018 is rotatably arranged on the folding base 2011, and the folding motor 2015 drives the driving rod 2018 to rotate through chain transmission, and the driving rod 2018 drives the two main gears 2017 to rotate.

[0035] Specifically, a spline hole (not shown) is arranged on the main gear 2017, and a spline (not shown) is arranged on each end of the driving rod 2018. Each end of the driving rod 2018 is movably arranged in the spline hole. An adjusting slide rail 2019 is arranged on the folding base 2011, and each of the box bodies 2013 is movably arranged on the adjusting slide rail 2019. Two adjusting screws 20110 are rotatably arranged on the folding base 2011 through bearings. The adjusting screws 20110 are threadedly connected with one of the box bodies 2013. A first synchronous chain 20111 is sleeved on the two adjusting screws 20110 through sprocket. A rotating handle 20117 is arranged on at least one of the adjusting screws 20110 to drive the adjusting screw 20110 to rotate. A threaded sleeve 20112 is sleeved on the adjusting screw 20110, and the threaded sleeve 20112 is threadedly connected with the other box body 2013. A second synchronous chain (not shown) is sleeved on the two threaded sleeves 20112 through sprocket to realize synchronous rotation. One end of one of the threaded sleeves 20112 is provided with a handle 20118 to manually drive the threaded sleeve 20112 to rotate. Of course, a motor can also be used to drive the threaded sleeve 20112 to rotate.

[0036] The working principle of the upper folding mechanism 202 and the lower folding mechanism 201 is as follows: the folding motor 2015 drives the driving rod 2018 to rotate through a chain, the driving rod 2018 drives the main gear 2017 to rotate through a spline fit, the main gear 2017 drives all the rotating shafts to rotate through the meshing between gears, the metal plate passes through the forming roller 2014 on the rotating shaft, and the 90° folding edge is formed through the gradual extrusion of the forming roller 2014. If it is necessary to adjust the shape of the folding edge, the forming roller 2014 can be directly replaced. The forming roller 2014 is fixedly arranged on the rotating shaft through a screw. If it is necessary to adjust the width of the upper and lower panels, the adjusting screw rod 20110 or the threaded sleeve 20112 can be rotated to drive the box body 2013 to move along the slide rail, so that the distance between the two box bodies 2013 is adjusted to match the change of the width of the plate. The two adjusting screw rods 20110 are synchronously rotated to ensure that the box body 2013 moves in parallel. The driving rod 2018 drives the main gear 2017 to rotate through a spline fit. This structure can adjust the transmission structure when the width of the box body 2013 is adjusted. The box body 2013 can move along the driving rod 2018, which is convenient for adjustment.

[0037] Specifically, the upper unwinding mechanism 102 and the lower unwinding mechanism 101 adopt the following structure:

[0038] Each of the upper unwinding mechanism 102 and the lower unwinding mechanism 101 comprises a feeding base 1011, two mounting seats 1012 are arranged on the feeding base 1011, at least one mounting seat 1012 is movably arranged on the feeding base 1011, a cantilever 1013 is arranged on each mounting seat 1012, a tensioning mechanism 1014 is arranged at the front end of the cantilever 1013, the tensioning mechanism 1014 comprises a tensioning base 1015 rotatably arranged at the front end of the cantilever 1013, a feeding motor 1016 is arranged on the mounting seat 1012 to drive the tensioning base 1015 to rotate, the cantilever 1013 is a square steel, and a feeding chain 10116 for driving the tensioning base 1015 is arranged in the square steel;

[0040] The four sliding grooves 10110 are arranged on the tensioning base 1015, and a tensioning top plate 10111 is movably arranged in each sliding groove 10110. An adjusting screw 10112 is movably arranged on the tensioning base 1015, and the adjusting screw 10112 is pivotally connected to the tensioning top plate 10111 through a connecting rod 10117.

[0043] The upper unwinding mechanism 102 and the lower unwinding mechanism 101 adopt a cantilever structure, and the tensioning mechanism 1014 for placing the coiled material is extended forward to avoid overlapping with the position of the feeding motor 1016. In this way, the position of the overall center of gravity can be ensured, and the overall height will not be too high.

[0044] The working principle of the upper unwinding mechanism 102 and the lower unwinding mechanism 101 is as follows: the workers hoist the metal plate material to the upper unwinding mechanism 102 and the lower unwinding mechanism 101 through a derrick, the clamping motor 1019 drives the two double-end screws 1018 to rotate, so that the mounting seat 1012 moves along the feeding base 1011, thereby inserting the two tensioning mechanisms 1014 into the center hole of the coiled material from both ends. The tensioning motor 10113 drives the adjusting screw 10112 to move forward and backward, thereby driving the tensioning top plate 10111 to move along the sliding groove 10110 through the connecting rod 10117, and the tensioning top plate 10111 is pushed outwards, thereby tensioning the coiled material. During feeding, the feeding motor 1016 drives the tensioning base 1015 to rotate through the double-row chain, thereby achieving active feeding.

When cutting is needed, the clamp clamps the composite board, and then the composite board moves forward to drive the cutting machine box 302 to move along the cutting guide rail 301, and the cutter cuts the composite board during the moving process. This structure can ensure that the moving direction of the cutter relative to the composite board is static during the cutting process, so as to ensure the cutting effect. After cutting, the clamp is released, and the reset cylinder 303 drives the cutting machine box 302 to reset. The cutter can be a hob or a long strip-shaped cutter, and the clamp can be a cylinder arranged in the cutting machine box 302. Since the structure itself is well known and commonly used in the industry, it is not shown in detail.
