The structure is ingenious and efficient and convenient.

(6) The present invention unwinds the upper and lower films synchronously by configuring the unwinding mechanism so that the unwinding motor drives the unwinding roller shaft. The first lifting cylinder drives the adjusting roller shaft to adjust the tension of the upper and lower films. The upper and lower films are separated by the film separation plate, and the upper and lower films are supported in layers by the upper support plate and the lower support plate respectively. On the one hand, the accuracy and efficiency of the feeding of the upper and lower films can be guaranteed. On the other hand, an installation gap is formed between the upper and lower films, which can facilitate the hose to enter between the upper and lower films more accurately and quickly. It is stable and practical.

After the cap-installing cylinder drives the receiving block to descend, the positioning cylinder drives the installation push rod to push the cap in the receiving hole onto the upper hose of the drainage bag, thereby realizing the rapid installation of the cap. The structure is ingenious, convenient and practical.

At the same time, according to the processing requirements, one side of the tube feeding mechanism 3 or the two sides of the tube feeding mechanism 3 is selected to start. If only one side of the drainage bag needs to be heat-sealed with the hose, the one side of the tube feeding mechanism 3 is started. If both ends of the drainage bag need to be heat-sealed with the hose, the two sides of the tube feeding mechanism 3 are started. When the tube feeding mechanism 3 is started, the hose in the first vibrating plate 311 enters the first discharge pipe 312 in turn, and the feeding cylinder 313 drives the feeding block 314 to move toward the first discharge pipe 312 until the material receiving through hole 317 on the feeding block 314 is connected with the first discharge pipe 312 and the material is received. , the feeding cylinder 313 sends the feeding block 314 to the pushing rod 316, the rotating motor 321 drives the rotating platform 322 to start rotating, and when any material receiving component on the rotating platform 322 is transferred to the material receiving block, the second driving cylinder 327 drives the connecting block 328 to be lifted, and after the connecting block 328 is connected to the sliding base 323, the first driving cylinder 326 drives the second driving cylinder 327 and the sliding base 323 to start rotating, and drives the connecting rod 325 to extend, and after the connecting rod 325 corresponding to the connecting block is extended, the pushing cylinder 315 drives the pushing The rod 316 slides, and the pushing rod 316 pushes the hose in the feeding block 314 out, and the hose is sleeved on the connecting rod 325, and then the second driving cylinder 327 drives the connecting block 328 to disengage from the sliding base 323, and the rotating platform 322 is rotated under the drive of the rotating motor 321. The rotation tangent direction of the rotating platform 322 at the upper film and the lower film is the same as the feeding direction of the upper film and the lower film. The connecting rod 325 and the hose on the rotating platform 322 enter between the upper film and the lower film under the rotation of the rotating platform 322. After the installation gap between the upper and lower membranes is formed, the rotating platform 322 stops rotating, and the upper and lower membranes also stop feeding. At the same time, the upper heat sealing cylinder 331 drives the upper heat sealing pressure block 333 to descend, and the lower heat sealing cylinder 332 drives the lower heat sealing block to lift, so that the hose is heat-sealed and fixed between the upper and lower membranes.

The second pneumatic scissors 715 clamp the hose after each third pneumatic finger 725 clamps the hose. After the hose is cut, each third pneumatic finger 725 drives each rotating cylinder to cut the hose. Each third pneumatic finger 725 drives the top slider 722 through the top cylinder 721 and drives the rotating motor 723 through the top lifting cylinder 720 to transfer the bent hose to the top of the bottom heat pressing block 729 and the drainage bag. The top heat pressing block 727 heat-seals and fixes the bent hose on the drainage bag to form a hanging belt through the driving of the top lifting cylinder 720 and the cooperation with the bottom heat pressing block 729.
