[0002] With the rapid development of animal husbandry, the new technology of feed film-wrapped silage has been widely applied. The round bale bundling machine is the main machine for the new technology of feed film-wrapped silage. The round bale bundling machine can bundle the harvested silage feed into high-density round bales. In order to avoid the round bale from being loose and falling off after being bundled, a layer of silk screen should be wrapped around the outside of the round bale to create good conditions for film-wrapped silage. The existing round bale bundling machine has a netting and cutting mechanism. In the actual operation process, the round bale may not be formed accurately due to inaccurate control of the netting and cutting mechanism, which affects the quality of the wrapped net. In addition, the netting and cutting mechanism is complex and has a high failure rate, which affects the reliability of the work.

[0003] The existing Chinese invention patent with the publication number CN202551724U discloses a netting mechanism of a round bale bundling machine, which aims to provide a netting and cutting mechanism of a round bale bundling machine with accurate control, good quality of wrapped net, and high reliability. The mechanism includes a frame body, a screen shaft, a support rod, a rubber roller, a driven roller, and a silk screen arranged on the screen shaft. The mechanism also includes a netting control mechanism and a cutting mechanism. The cam of the cutting mechanism is parallel to the large gear and is fixed as a whole. The cam is designed as a missing angle disc shape obtained by cutting a disc into a round corner. The disc is divided into an angle section and an arc section. A tension pulley is arranged obliquely below the rotary sleeve of the netting control mechanism. A belt pulley is arranged at the end of the rubber roller shaft and is connected to the input belt pulley through a transmission belt. The utility model is suitable for the net wrapping operation of round bale silage feed. However, the device cannot stop the netting at any time and has no hysteresis. SUMMARY

[0004] Therefore, the utility model aims to provide a netting device and bundling machine to solve the problem that the existing device cannot stop the netting at any time.

The first driving rubber roller and the second driving rubber roller are both in contact with the driven rubber roller to fix the net on the net bundle. The net cutting knife is arranged below the second driving rubber roller.

[0007] Furthermore, an unwinding roller is arranged between the first driving rubber roller and the net bundle. The net passes through the unwinding roller and enters the gap between the first driving rubber roller and the driven rubber roller.

[0008] Further, the driven rubber roller is connected with a driven rubber roller tension spring.

[0009] Further, the rack is provided with a slitting blade guide groove for guiding the slitting blade.
