As shown in fig. 1 and 2, the utility model provides a woven bag cutting device, it includes portal frame 1, permanent magnet 2, electro-magnet 3, cutting knife 4, buffering subassembly 5 and woven bag conveyer belt 6. The woven bag conveying belt 6 penetrates through the middle of the portal frame 1, and the moving direction and the cutting direction of the woven bags are perpendicular to each other.

The upper surface of portal frame 1 has seted up a level along its length direction and has led to groove 11, permanent magnet 2 with the groove 11 sliding connection is led to the level, is in simultaneously the intermediate position department of the both ends tip of the upper surface of portal frame 1 respectively installs an electro-magnet 3, is first electro-magnet 31 and second electro-magnet 32 respectively, first electro-magnet 31 with second electro-magnet 32 symmetry sets up. Here, the left end of the permanent magnet 2 is an N pole, and the right end thereof is an S pole; the first electromagnet 31 is positioned at the left end of the permanent magnet 2, and one end of the first electromagnet 31 close to the permanent magnet 2 is in an S-level state; the second electromagnet 32 is located at the right end of the permanent magnet 2, and one end of the second electromagnet 32 close to the permanent magnet 2 is located at the N-level. The cutting knife 4 is installed one side that permanent magnet 2 is close to braided bag conveyer belt 6 is cutting the during operation, and first electro-magnet 31 and second electro-magnet 32 are circular telegram in turn to attract permanent magnet 2 to be close to or keep away from, thereby drive cutting knife 4 horizontal motion and carry out cutting work.

In the cutting process, in order to facilitate the control of the first electromagnet 31 and the second electromagnet 32 to work, a photoelectric switch 7 and a controller are respectively installed at one end of the upper surface of the portal frame 1 close to the first electromagnet 31 and one end of the upper surface of the portal frame close to the second electromagnet 32, the first electromagnet 31 and the second electromagnet 32 are respectively electrically connected with the corresponding controllers, and the controllers are electrically connected with the photoelectric switch 7; when permanent magnet 2 is close to photoelectric switch 7, photoelectric switch 7 receives behind the signal that permanent magnet 2 is close to transmit this signal for the controller with the mode of signal of telecommunication, then the controller control 3 outage of the electro-magnet corresponding with it, the electro-magnet 3 circular telegram of opposite side this moment to attract permanent magnet 2 to the direction motion of being close to the electro-magnet 3 of circular telegram, through adopting above-mentioned technical scheme, make permanent magnet 2 can be horizontal reciprocating motion at the cutting in-process, thereby drive cutting knife 4 and do horizontal reciprocating motion and carry out cutting work. Through setting up photoelectric switch 7, not only be convenient for control electro-magnet 3 and open or close, make the degree of automation of this device higher moreover.

Simultaneously, in the cutting process, in order to make 2 movements of permanent magnet more smooth, so 2 permanent magnet in this embodiment set up to "worker" style of calligraphy, lead to groove 11 sliding contact's both sides middle part at 2 permanent magnet and level simultaneously and have all seted up a spherical groove, as shown in fig. 3, install a ball 8 in the spherical groove, through setting up ball 8 to become roll connection with the sliding connection that permanent magnet 2 and level led to between the groove, reduced the frictional force between 2 and the groove 11 lateral walls that lead to the level of permanent magnet, make 2 movements of permanent magnet more smooth, thereby improved cutting efficiency.
