[0025] Figure 1 This is a schematic diagram of an embodiment of an edge sealing device for tarpaulin processing according to the present invention. Figure 1 As shown, in one or more embodiments, the present invention provides an edge-sealing device for tarpaulin processing, comprising a frame 1, an edge-folding structure 2, a cam-driven structure 3, and a hot-melt pressing structure 4, each of which is mounted on the frame 1. For example, a single frame 1 can seal one side of a tarpaulin; two frames 1 arranged opposite each other and connected by a connecting beam can simultaneously seal both sides of the tarpaulin.

[0026] Continue to see Figure 1In one or more embodiments, the frame 1 is in a substantially rectangular plate shape, and a side plate 11 is arranged on the frame 1 and used to support the tarpaulin. It can be understood that the two ends of the edge sealing device can be provided with a tarpaulin conveying structure to pull the tarpaulin through the edge sealing device and tension the tarpaulin. Further, a workbench can be provided between the two frames 1 to support the tarpaulin. In one or more embodiments, a motor seat is arranged on the frame 1, and the motor seat is used to install the cam driving structure 3. Further, a slot is formed on the side plate 11 to avoid the hot melt pressing structure 4.

[0027] Figure 2 is a schematic view of the internal structure of the edge sealing device for tarpaulin processing according to the present application, Figure 3 is another schematic view of the internal structure of the edge sealing device for tarpaulin processing according to the present application. Figure 2 schematically shows a view of the edge folding member 22 pressing and folding the tarpaulin edge portion, Figure 3 schematically shows a view of the edge folding member 22 stopping pressing and folding. As Figure 1 , Figure 2 and Figure 3As shown, in one or more embodiments, the folding structure 2 comprises a starting edge guiding block 21 mounted on the edge plate 11 and a folding member 22 rotatably mounted on the edge plate 11. The starting edge guiding block 21 and the folding member 22 are arranged in sequence along the conveying direction of the tarpaulin. The starting edge guiding block 21 is formed with a starting edge guiding slope facing the tarpaulin and capable of lifting the tarpaulin. Specifically, the starting edge guiding slope is in abutment with the upper side of the edge plate 11, and the starting edge guiding slope can be understood as a curved surface gradually rising on the side of the edge plate 11 close to the rack 1 and gradually extending away from the rack 1. Further, the folding member 22 is rotatably mounted on the edge plate 11. The folding member 22 comprises a pressing and folding portion 221 arranged in parallel with the edge plate 11 and a connecting portion 222 connected with the cam driving structure 3. The pressing and folding portion 221 and the connecting portion 222 are arranged at an angle.

For example, the angle between the pressing and folding portion 221 and the connecting portion 222 is between 120° and 140°. For example, the angle between the pressing and folding portion 221 and the connecting portion 222 is 130° or 134°. Further, a lifting seat 23 is arranged on the edge plate 11 to raise the height of the folding member 22. Specifically, two connecting ears 24 are arranged opposite to each other on the lifting seat 23, and through holes are formed in the two connecting ears 24. A rotating shaft 25 is arranged at the bending portion of the folding member 22, and the two ends of the rotating shaft 25 are arranged in the through holes of the connecting ears 24, respectively. Further, an avoiding groove 231 is arranged on the lifting seat 23, which is arranged on the side of the lifting seat 23 close to the rack 1, for avoiding the rotating path of the connecting portion 222. The cam driving structure 3 drives the connecting portion 222 to rotate, and the pressing and folding portion 221 rotates accordingly, thereby folding the lifted tarpaulin to form a folded edge, and the folded edge is in a U shape with the opening facing outward.

[0028] Continuing to refer to Figure 1 , Figure 2 and Figure 3In one or more embodiments, the cam driving structure 3 comprises a driving motor 31 mounted on the frame 1, a cam 32 mounted on the driving motor 31, and a connecting rod 33 connecting the cam 32 and the connecting portion 222.

The driving motor 31 is fixed on a motor base, and the cam 32 is fixed on a motor shaft of the driving motor 31. The cam 32 is in a substantially circular shape and is coaxially arranged with the motor shaft. A hinged column is arranged on the cam 32, which is offset from the edge of the cam 32 and is not coaxial with the cam 32. The two ends of the connecting rod 33 are respectively connected with the cam 32 and the connecting portion 222 in a hinged matching connection. The two ends of the connecting rod 33 are formed with a sleeve ring 34, which is sleeved on the hinged column, so that the connecting rod 33 and the cam 32 form a hinged matching connection. Further, a connecting ring 35 is formed on the connecting portion 222. A connecting piece (not shown in the figure) is arranged between the connecting portion 222 and the connecting rod 33, which comprises a first connecting column matched with the connecting ring 35, a second connecting column matched with the sleeve ring 34, and a connecting plate connecting the first connecting column and the second connecting column. The connecting piece is respectively connected with the connecting portion 222 and the connecting rod 33 in a hinged matching connection.

[0029] Continuing to refer to Figure 1 , Figure 2 and Figure 3 In one or more embodiments, the hot melt pressing structure 4 comprises a hot melt plate 41 arranged between the folding member 22 and the side plate 11, and pressing rollers 42 arranged on both sides of the tarpaulin. The hot melt plate 41 can be an electric heating plate or a steam heating plate, which is not limited in particular. The tarpaulin edge is folded by the folding member 22, and the hot melt plate 41 is arranged between the tarpaulin body and the folded edge to heat both. Further, the length of the hot melt plate 41 is greater than the length of the folding member 22, so that the tarpaulin passing through the folding member 22 can be close to the hot melt plate 41 when it is folded again next time, avoiding poor hot melt effect of the tarpaulin. The pressing rollers 42 are connected with a power source, which is an electric motor and is installed in the frame 1. The two pressing rollers 42 are driven to rotate towards each other by the electric motor, and the folded edge and the tarpaulin body are pressed to complete the edge sealing.
