The punching device of the buckle-fastening machine is arranged on the lower side of the lower buckle-feeding device 4, and can buckle the tarpaulin passing through the upper buckle-feeding device 5 and the lower buckle-feeding device 4 directly from the lower side. After the tarpaulin is turned upside down, the tarpaulin can be buckled directly without turning the tarpaulin over, thus eliminating the equipment for turning the tarpaulin over, greatly reducing the volume of the tarpaulin production equipment, and also reducing the cost of the tarpaulin production equipment. Moreover, since the tarpaulin does not need the reverse side, the buckle-fastening speed of the tarpaulin is increased.

[0029] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0030] Specific: such as Figure 1~2 As shown: the upper button feeding device 5 is arranged at intervals on the upper side of the lower button feeding device 4, the stamping die is arranged on the upper side of the upper button feeding device 5, and the stamping device is arranged on the lower side of the lower button feeding device 4. The upper button feeding device 5 and the lower button feeding device 4 are both provided with a clamping portion 801 at one end close to the stamping device, and the stamping die and the stamping device are both arranged opposite to the clamping portion 801. A stamping portion with a concave middle portion is arranged on the lower side of the stamping die, and the stamping portion is arranged opposite to the clamping portion 801.

[0031] The punching device includes a punching cylinder 1 and a punching rod. The punching cylinder 1 is vertically arranged directly below the clamping part 801. The piston rod of the punching cylinder 1 is arranged upward. The punching rod is arranged directly opposite to the clamping part 801. The piston rod of the punching cylinder 1 is connected to the punching rod and pushes the punching rod to rise and fall vertically, so that the punching rod cooperates with the punching part of the punching die to complete the buckling of the tarpaulin.

[0032] The stamping cylinder 1 is also connected to a lifting rod 3, which is arranged vertically. The lifting rod 3 has two lifting rods symmetrically arranged on both sides of the clamping part 801. The upper end of the lifting rod 3 is provided with a conical pushing part with a diameter gradually increasing from bottom to top. The pushing part pushes the corresponding side of the clamping part 801 to swing, thereby realizing the opening of the clamping part 801. And because the lifting rod 3 and the stamping rod are lifted and lowered synchronously, it can ensure that the clamping part 801 and the stamping rod cooperate more accurately. A lifting plate 2 is installed on the piston rod of the stamping cylinder 1, and the lifting rod 3 is installed on the lifting plate 2 and rises and falls synchronously with the lifting plate 2. The stamping cylinder 1 can be replaced by an electric cylinder or a hydraulic cylinder.

[0033] like Figure 2 As shown: the structures of the lower buckle feeding device 4 and the upper buckle feeding device 5 are the same, both of which include a mounting plate 6, a push plate 9 and a power device. In this embodiment, the power device is a buckle feeding cylinder 7. The mounting plate 6 is horizontally arranged. Clamping arms 8 are symmetrically arranged on both sides of the upper part of the mounting plate 6. One end of the clamping arm 8 is hinged to the mounting plate 6, and the other end extends out of the mounting plate 6 to form a clamping portion 801. The two clamping arms 8 are arranged at intervals, so that a guide groove is formed between the two clamping arms 8. The push plate 9 is slidably arranged in the guide groove and guided by the clamping arm 8. The buckle feeding cylinder 7 is horizontally installed on the mounting plate 6. The piston rod of the buckle feeding cylinder 7 is connected to the push plate 9 and pushes it to move back and forth, and pushes the tarpaulin buckle into the clamping portion 801. The power device can also be an electric cylinder or a hydraulic cylinder.

[0034] A pressure plate is provided on the upper side of the push plate 9, and the pressure plate is detachably connected to the mounting plate 6. The clamping arm 8 is also provided between the pressure plate and the upper mounting plate 6. The pressure plate can guide both the push plate 9 and the clamping arm 8. A vertical through hole is provided in the middle of the pressure plate to form a blanking hole. The tarpaulin buckle falls into the guide groove through the blanking hole, and is pushed into the clamping portion 801 through the push plate 9.

[0035] The clamping portion 801 is arranged on one side adjacent to the two clamping arms 8. The clamping portion 801 is an arc-shaped portion with a concave middle portion. The two clamping portions 801 are combined to form a circular ring. A boss for supporting the tarpaulin buckle is arranged at the bottom of the clamping portion 801, so that the tarpaulin buckle can be supported.

[0036] A side of the push plate 9 close to the clamping portion 801 is provided with an arc-shaped pushing portion 901 with a concave middle portion. The pushing portion 901 and the two clamping portions 801 together form a circular through hole, so that the tarpaulin buckle can be accurately positioned.

[0037] Each clamping arm 8 is equipped with a roller 10, the rotating shaft of the roller 10 is arranged horizontally, and a clearance hole 601 is arranged on the mounting plate 6, the clearance hole 601 corresponds to the roller 10 one by one, and the clearance hole 601 is arranged on one side of the roller 10. The pushing part of the lifting rod 3 passes through the clearance hole 601 and fits with the roller 10, so that the clamping arm 8 is pushed to swing through the roller 10, thereby realizing the opening of the clamping part 801. An elastic element is arranged between the two clamping arms 8. In this embodiment, the elastic element is a spring, and the spring is in a stretched state, so that the two clamping arms 8 clamp the tarpaulin buckle.

[0038] A feed trough is provided on one side of the lower buckle feeding device 4, and a limit plate is provided on the other side. The feed trough is an arc or inclined shape that gradually moves away from the lower buckle feeding device 4 from bottom to top. The feed trough is a T-shaped slot with an opening toward the lower buckle feeding device 4. The lower part of the tarpaulin buckle is provided in the feed trough, so that it is sequentially transported to the lower buckle feeding device 4 under the action of gravity. The limit plate can ensure that the tarpaulin buckle input from the feed trough 6 accurately enters the lower buckle feeding device 4.

[0039] The working method of the buckle-fastening machine is as follows: first, the upper and lower parts of the tarpaulin buckle enter the upper buckle feeding device 5 and the lower buckle feeding device 4 respectively, and then the punching cylinder 1 pushes the punching rod and the lifting rod 3 to rise, and the lifting rod 3 preferentially pushes the lower buckle feeding device 4 to open. At this time, the punching rod contacts the lower part of the tarpaulin buckle on the lower buckle feeding device 4 and pushes it to move upward, and then the lifting rod 3 pushes the upper buckle feeding device 5 to open. At this time, the punching rod contacts the tarpaulin buckle on the upper buckle feeding device 5 again and pushes it to move upward, and cooperates with the punching die to realize the buckling of the tarpaulin.
