[0007] Furthermore, the rotating shaft is rotatably arranged on the frame via a bearing.

[0008] Furthermore, both ends of the knife shaft are integrally provided with a flat body structure matching the slot of the rotating shaft.

[0009] Furthermore, a plurality of groups of knife seats are distributed on the knife shaft, and a blade is fixedly provided on one side of each group of knife seats.

[0010] Furthermore, each group of the knife seats is fixed on the knife shaft by bolt locking.

[0011] The beneficial effect of the utility model is that rotating shafts are arranged at both ends of the frame, and a slot matching the knife shaft is arranged on the rotating shaft. When replacing, only the sliding sleeve on the knife shaft needs to be removed, and then the knife shaft is removed from the rotating shaft to realize quick knife change.

[0018] In order to make those skilled in the art better understand the technical solution of the utility model, the following Figure 1-5 The utility model is further analyzed.

[0019] like Figure 1-5 As shown, a longitudinal cutting mechanism for convenient tool changing is characterized in that it includes a frame 1, a knife shaft 2, a sleeve 3, a spacer sleeve 4 and a motor 5. A rotating shaft 6 is arranged on the inner side of both ends of the frame 1 through bearings, and one end of the rotating shaft 6 is provided with a slot 601 matching the knife shaft 2. The two ends of the knife shaft 2 are respectively inserted into the rotating shaft 6 at both ends of the frame 1. The sleeve 3 is arranged on the outer periphery of the connection between the knife shaft 2 and the rotating shaft 6. The spacer sleeve 4 is fixed at both ends of the knife shaft 2 by bolts. A spring 7 is arranged between the spacer sleeve 4 and the sleeve 3. The motor 5 is arranged at one end of the frame 1 and is connected to one group of the rotating shafts 6 through a coupling to drive the knife shaft 2 to operate.

[0020] In this embodiment, preferably, the rotating shaft 6 is rotatably disposed on the frame 1 via a bearing.

[0021] In this embodiment, preferably, both ends of the knife shaft 2 are integrally provided with a flat body structure 201 matching the slot 601 of the rotating shaft 6 .

[0022] In this embodiment, preferably, a plurality of groups of knife seats 8 are distributed on the knife shaft 2 , and a blade 9 is fixedly provided on one side of each group of knife seats 8 .

[0023] In this embodiment, preferably, each group of the knife seats 8 is fixed on the knife shaft 2 by bolt locking.

[0024] The specific working principle of the utility model is as follows: when removing the knife, first squeeze the sliding sleeve 3 toward the spacer sleeve 4 to make the sliding sleeve 3 leave the connection between the knife shaft 2 and the rotating shaft 6, and then take out the flat body structure 201 at both ends of the knife shaft 2 from the slot 601 of the rotating shaft 6, and the whole knife shaft 2 can be removed from the frame 1; when installing the knife, first install the spacer sleeve 4 and the spring 7 on the flat body structure 201 at both ends of the knife shaft 2, and lock and fix the spacer sleeve 4 with bolts, and then insert the sliding sleeve 3 into the other end of the spring 7, and squeeze the sliding sleeve 3 toward the spring 7, and then insert the flat body structure 201 at both ends of the whole knife shaft 2 into the slot 601 of the rotating shaft 6, and then loosen the sliding sleeve 3 so that it is pressed against the connection between the knife shaft 2 and the rotating shaft 6 under the thrust of the spring 7, and the flat body structure 201 that clamps the knife shaft 2 cannot slide out from the slot 601 of the rotating shaft 6, so that the whole knife shaft 2 is installed on the frame 1.

[0025] The technical solution provided by the present application is introduced in detail above.
