The second electric telescopic cylinder 20 is horizontally fixedly installed on the side of the connecting plate 18, the baffle 21 is fixedly sleeved on the second electric telescopic cylinder 20, and the clamping plate 22 is fixedly installed on the output end of the second electric telescopic cylinder 20.

[0039] The transmission components include a third gear 23, a bracket 24, a pin 25, two universal joints 26, a telescopic link 27, a plurality of worm wheels 28 and a worm 29. The plurality of worm wheels 28 are respectively fixedly sleeved on the plurality of rotating shafts 5. The worm 29 is rotatably sleeved in the frame 4 and meshed with the plurality of worm wheels 28. The bracket 24 is fixedly mounted on the end of the cylinder 2.

The ends of the two universal joints 26 that are away from each other are respectively fixedly connected to the pin 25 and the ends of the worm 29. The telescopic link 27 has a telescopic function and can transmit torque.

[0040] When the device is used to wrap materials, the device is started, the first motor 10 runs, driving the main shaft 12 and the two first gears 13 to rotate, the two first gears 13 drive the two first gear rings 14 to rotate, and the first gear rings 14 drive the cylinder 2 to rotate in the frame 1.

[0041] According to the diameter of the material, the length of the first electric telescopic cylinder 3 is controlled by the control terminal, so that multiple groups of conveying components can clamp and fix the material to be wrapped and packaged.

[0042] When the cylinder 2 rotates, the multiple third gears 23 are driven to rotate. Under the interference of the third gear ring 19, the multiple third gears 23 rotate while rotating. The third gear 23 rotates, driving the pin rod 25 to rotate. The pin rod 25 drives the telescopic connecting rod 27 to rotate through the universal joint 26. The telescopic connecting rod 27 drives the worm 29 to rotate through another universal joint 26. The worm 29 drives the multiple worm wheels 28 to rotate.

[0043] After the front end of the material reaches the area of ​​the ring body 7, the sensor device 35 senses it and feeds back the signal to the control terminal, the second motor 15 starts, so that the second gear 16 rotates, and the second gear 16 drives the ring body 7 to rotate through the second ring gear 17, and the rotation direction is opposite to the rotation direction of the cylinder 2. In the initial state of rotation of the ring body 7, the second electric telescopic cylinder 20 is in a retracted state, the clamping plate 22 is in close contact with the baffle 21, and the end of the stretch film is clamped. The ring body 7 rotates, driving the stretch film roll on the insertion rod 8 to rotate, so that the stretch film is wrapped around the material to be packaged, and the material is wrapped. As the material moves, the second electric telescopic cylinder 20 extends, so that the clamping plate 22 is separated from the baffle 21, and the end of the stretch film is released and wrapped, thereby realizing the packaging of the material.

[0044] During the conveying process, the material is clamped and limited by multiple groups of conveying components, so that the material is conveyed along a horizontal straight line without deviation due to uneven force on the winding end, thus ensuring the packaging quality.

[0045] During the winding process, the cylinder 2 drives the material to rotate, and the ring body 7 drives the winding packaging film to rotate, so that the packaging film and the material rotate in opposite directions at the same time, making the packaging more efficient.

[0046] When the material is packaged to the tail end, the stretch film needs to be cut off. The sensor device 35 senses it. After receiving the signal, the control terminal sends a command to extend the second electric telescopic cylinder 20 to separate the splint 22 from the baffle 21. During the rotation of the stretch film, it is blocked by the extended end of the second electric telescopic cylinder 20. Then the second electric telescopic cylinder 20 shortens, and the splint 22 cooperates with the baffle 21 to pull the stretch film apart and tighten the broken end at the same time to prepare for the next wrapping and packaging.

[0047] A cavity 30 is provided inside the cylinder 2 at the output end, and a sealing ring 31 is rotatably installed at the tail end.

A plurality of air holes 34 are provided on the inner wall of the cylinder 2 at the output end, and the plurality of air holes 34 are all connected to the cavity 30.

[0048] The area where the material is wrapped will be transported to the cylinder 2 located at the overall output end of the equipment. The fan device 32 is turned on to introduce air flow into the cavity 30 through the duct 33. The air flow is led out from multiple air holes 34. According to the type of wrapping film used, air flow with a suitable temperature is introduced to perform wind heat treatment on the wrapping film to make it shrink quickly, making the packaging more compact and improving the packaging quality.
