[0019] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0020] It should be noted that the directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only references to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0021] like Figure 1-2 As shown, a blade mounting structure of a cutting machine, the cutting machine has a frame, on which a fixed mold 2 and a top plate 1 for positioning bottles and cans to be cut are fixedly connected, the blade fixing structure includes a pair of blade racks 4 that are relatively arranged on both sides of the bottle body fixed mold 2 and below the top plate 1, and a rotating disk 44 connected to the blade racks 4, the rotating disk 44 can rotate on a horizontal plane relative to the bottle body fixed mold 2, and the blade rack 4 is connected to the rotating disk 44 through an adjusting box 41.

[0022] The adjusting box 41 is connected to the blade holder 4 at one end close to the bottle body fixing mold 2, and the pair of blade holders 4 arranged opposite to each other include an upper plate and a lower plate, a blade is clamped between the upper plate and the lower plate, and a plurality of positioning holes are arranged on the upper plate and the lower plate, so that the blade and the upper and lower plates cooperate through different positioning holes and positioning bolts to achieve adjustable extension length of the blade relative to the upper and lower plates.

[0023] A discharge assembly is arranged between the rotating disk 44 and the top plate 1, and the discharge assembly includes an annular cover surrounding the movement trajectory of the blade holder 4 and a discharge guide port opened on the annular cover, and the discharge guide port is connected to a dustpan-shaped guide slideway inclined downward, so that waste materials from the cut bottle mouth can be discharged under inertia.

[0024] like Figure 3As shown in the figure, an adjusting plate 411 is arranged inside the adjusting box 41. The adjusting plate 411 is rotationally connected to a rotating disk 44 through an adjusting rotating shaft, and the adjusting plate 411 is in transverse transmission cooperation with the blade holder 4 through its movable head 4111. The top of the adjusting box 41 is in sliding fit with the blade holder, and the box body of the adjusting box 41 is in positioning fit with the rotating disk 44; the movable head 4111 is a sphere, and a movable cavity for accommodating the sphere is arranged inside the lower plate of the blade holder 4. The adjusting plate 411 rotates around the adjusting rotating shaft to change the transverse position of the sphere (the height of the movable cavity is greater than the diameter of the sphere, so that the sphere can rotate and move up and down inside the movable cavity, thereby only driving the blade holder 4 to move transversely). The top of the box body of the adjusting box 41 guides and limits the blade holder 4, so that the adjusting plate 411 drives the blade holder 4 to move transversely on the same horizontal plane relative to the upper end of the adjusting box 41.

[0025] As Figure 4-5 As shown in the figure, a triangular groove 402 is arranged at the upper end of the adjusting box 41. The lower plate of the blade holder 4 is an I-shaped frame 403, and the lower end of the I-shaped frame 403 is embedded in the triangular groove 402, so that the blade holder 4 can slide relative to the upper end of the adjusting box 41.

[0026] A transmission column 53 and a rotating motor are connected to the lower part of the center of the rotating disk 44.

[0027] The adjusting plate 411 can be rotationally connected to the rotating disk 44 through a damping rotating shaft, so that the rotation of the adjusting plate 411 is stable.

[0028] During use, the semi-finished product of the bottle or can to be cut is placed upside down in the bottle body fixing mold 2 for positioning, and the part to be cut is exposed at the lower end of the fixing mold 2. Set the transverse position of the blade end in the blade holder 4 so that the blade is close to the bottle or can to be cut. The rotating motor drives the transmission column 53 to rotate, and then drives the rotating disk 44 to rotate. The adjusting plate 411 is driven to rotate around the rotating shaft through a driving device (which can be pneumatic or electric drive, such as a cylinder, a telescopic rod, an electric rotating shaft), and then drives the blade holder 4 to slide relative to the upper end of the adjusting box 41 towards the bottle or can to be cut until it cuts into the bottle or can, completing the "knife feeding"; the blade holder 4 and the blade rotate driven by the rotating disk 44, cutting around the circumference of the bottle or can to be cut. The cutting waste falls below the fixing mold 2 and is cleared out. The bottle or can with the cut is taken out of the fixing mold 2 manually or by a manipulator, and the bottle or can to be cut is put in again.

[0029] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
