[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] Referring to Figure 1 The present application provides a cutter adjusting device of a paper tube cutting machine, which comprises a screw rod 1, two guide rods 2 and a cutter assembly. The cutter assembly comprises a support 3, a first cylinder 4, a second cylinder 5 and a cutter 6. The support 3 is a square frame, the screw rod 1 passes through the support 3, the first cylinder 4 is installed at the top end of the support 3, the driving end of the first cylinder 4 passes through the support 3, the driving end of the first cylinder 4 is provided with a circular adjusting piece 7, the adjusting piece 7 has a thread matched with the screw rod 1, the bottom of the support 3 is provided with two shaft sleeves 8, the two guide rods 2 pass through the two shaft sleeves 8, the second cylinder 5 is fixed to the bottom of the support 3, the cutter 6 is connected to the driving end of the second cylinder 5, and the screw rod 1 is driven to rotate by a motor 9.

[0016] The cutter 6 is circular and is rotatably arranged in a cutter holder 10, and the cutter holder 10 is connected to the driving end of the second cylinder 5. The circular and rotatable cutter 6 can make the cut smooth when cutting the paper tube, thereby improving the product yield.
