Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0015] like Figure 1-3The illustrated device for covering the filter cloth of a corrugated pipe for drainage engineering comprises a workbench 1 and a cloth-wrapping assembly arranged above the workbench 1. The cloth-wrapping assembly comprises a support plate 2, a rotating column 4 and a rotating disk 11. The support plate 2 is fixedly mounted on the workbench 1. Two groups of rotating disks 11 are rotatably mounted on one side of the support plate 2. A packaging opening 6 is provided on the outer wall of the support plate 2. The two groups of rotating disks 11 are symmetrically arranged and are both tangent to the edge of the packaging opening 6. Two groups of rotating columns 4 are arranged on one side of the support plate 2 away from the rotating disk 11. The two groups of rotating columns 4 are both rotatably mounted on the workbench 1. The two groups of rotating columns 4 are symmetrically arranged on both sides of the packaging opening 6. A motor 3 is arranged at the bottom of the rotating column 4. The motor 3 is fixedly mounted on the workbench 1. The output end of the motor 3 is fixedly connected to the rotating column 4. The axis of the rotating column 4 is perpendicular to the workbench 1.

[0016] A cloth roller 9 is installed at the bottom of one side of the workbench 1, and the cloth roller 9 is arranged on one side of the support plate 2 where the turntable 11 is installed. A guide rod 10 is arranged above the cloth roller 9, and the guide rod 10 is rotatably installed on the side of the workbench 1 and parallel to the table surface of the workbench 1.

[0017] Two rotating wheels 8 are rotatably mounted on the outer wall of the support plate 2 away from the turntable 11. The two rotating wheels 8 are symmetrically arranged. The two rotating wheels 8 are made of rubber and the edges of the two rotating wheels 8 are fitted. A hot air pipe 5 is arranged on the side of one of the rotating wheels 8 away from the support plate 2. The hot air pipe 5 is fixedly connected to the outer wall of the support plate 2. A clamping groove 7 is provided through the upper outer wall of the support plate 2. The clamping groove 7 is connected to the packaging port 6. One opening of the clamping groove 7 is arranged between the two groups of turntables 11, and the other opening is arranged between the two groups of rotating wheels 8.

[0018] Embodiment: A filter cloth is wound around the outside of the cloth roller 9, a mounting frame is installed at the bottom of the workbench 1, the end of the cloth roller 9 is connected to the mounting frame through a damping bearing, and the cloth roller 9 is arranged parallel to the table surface of the workbench 1. The external bellows forming machine transports the end of the bellows to the top of the workbench 1, and the end of the bellows enters the packaging port 6 of the support plate 2 from above the cloth roller 9. After the end of the bellows reaches between the two rotating columns 4, the external forming machine stops transporting, and the operator pulls the filter cloth on the cloth roller 9. The starting end of the filter cloth passes through the gap between the guide rod 10 and the workbench 1, passes through the packaging port 6 from the bottom of the bellows, and pulls the starting end of the filter cloth to the end of the bellows, covering the end of the bellows from bottom to top, so that the two rotating columns 4 clamp the end of the bellows covered with the filter cloth, and the edges on both sides of the filter cloth are merged above the bellows. After the edges are merged, the merged part is embedded between the two rotating wheels 8 at the same time, so that the two fitted rotating wheels 8 can clamp the merged part of the filter cloth. At the same time, the merged part of the filter cloth is also embedded in the clamping groove 7. The part of the filter cloth that does not pass through the clamping groove 7 naturally unfolds to both sides of the clamping groove 7. The unfolded part passes between the turntable 11 and the outer wall of the corrugated tube. The edge of the filter cloth passing through the turntable 11 will fit the edge of the turntable 11. Because the two ends of the cloth roller 9 are connected to the bottom mounting clamp of the workbench 1 through the damping bearing, there will be resistance when the operator pulls the filter cloth. After the starting end of the filter cloth initially covers the end of the corrugated tube, the part of the filter cloth from the starting end to the cloth roller 9 is in a tight state. Therefore, when the filter cloth in a tight state passes under the turntable 11, the edge of the side of the filter cloth fits the edge of the turntable 11. The air outlet of the hot air duct 5 is located on one side of the merged part of the filter cloth.

[0019] After the filter cloth and the ends of the bellows are initially coated, the paused forming machine and motor 3 can be started. The forming machine continues to transport the bellows, the motor 3 drives the rotating column 4 to rotate, and high-temperature air is blown out from the hot air pipe 5. The high-temperature air heats the merged part of the filter cloth. The forming machine drives the bellows at a uniform speed, and the rotating column 4 rotates at a uniform speed. Therefore, the merged part of the filter cloth also moves at a uniform speed. The heating time of each merged part is the same, so that the merged part of the filter cloth can be evenly heated. The merged part is softened and then bonded, and the two rotating columns 4 help the filter cloth to fit the outer wall of the corrugated tube and clamp the corrugated tube covering the filter cloth. As the corrugated tube advances and is driven by the rotating column 4, the filter cloth follows the corrugated tube to advance, and the filter cloth on the cloth roller 9 is continuously pulled, and the cloth roller 9 rotates accordingly. The filter cloth passing through the turntable 11 can pass through the clamping groove 7 more smoothly. The existence of the clamping groove 7 and the turntable 11 is to help the two side edges of the filter cloth to merge smoothly, and after the smooth merging, they enter between the two rotating wheels 8. The rotating wheels 8 clamp the merged part of the filter cloth, and the hot air pipe 5 continuously heats the merged part so that the two side edges of the filter cloth are bonded and fixed to each other, so that the key step of covering the filter cloth on the outside of the corrugated tube is automated.

[0020] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0021] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
