An outlet 7 is arranged between the inner turntables 6, and a motor 8 is drivingly installed on one side of the inner turntable 6;

[0029] On the other side of the cutter head 1, a wheel disc 9 is fixedly installed. The function of the wheel disc 9 is to rotatably install a protective cover 11 through a rotating groove 10. During the rotation of the protective cover 11, the protective door 12 on its surface can be in alignment with the cutting outlet 7, and this position is the part where the tool is output. A rotating groove 10 is provided in the middle of the wheel disc 9, and it is the part where the protective cover 11 rotates. The protective cover 11 is rotatably arranged inside the rotating groove 10. One side of the protective cover 11 is provided with a protective door 12, and the protective door 12 is the part where the tool is directly output. One side of the wheel disc 9 is provided with a wing plate 13. The function of the wing plate 13 is to install a rotor 16, and the rotor 16 drives the protective cover 11 to rotate inside the rotating groove 10 through a friction wheel 17; a rotor 16 is installed on one side of the wing plate 13, and a friction wheel 17 is installed at the output end of the rotor 16, and the friction wheel 17 is in frictional contact with the protective cover 11 by extrusion.

[0030] For a protective door at the cutting outlet of a tool magazine, a bearing seat 14 is provided on one side of the wing plate 13. The bearing seat 14 and the bearing 15 are components that ensure the rotation of the output shaft of the rotor 16; the bearing 15 is installed inside the bearing seat 14, and the output shaft of the rotor 16 is rotatably installed inside the bearing 15.

[0031] For a protective door at the cutting outlet of a tool magazine, an inner turntable 6 is arranged in an array around the cutter head 1, which can align the cutting outlet 7 with tools at different positions. The inner turntable 6 is of a rotary structure.

[0032] For a protective door at the cutting outlet of a tool magazine, the sizes of the cutting outlet 7 and the protective door 12 are twice the size of the tool magazine 4, ensuring that the tool can be output at the cutting outlet 7 and the protective door 12.

[0034] An installation component 3. The installation component 3 is a component for fixing this device; the installation component 3 includes an upper flange 18 installed on one side of the cutter head 1, and the upper flange 18 is used to be directly connected to the main body part of this device; the bottom of the upper flange 18 is fixedly installed with a lower flange 19 through a rod, and the lower flange 19 is the external connection part of this device.

[0035] For a protective door at the cutting outlet of a tool magazine, screw holes are provided around the upper flange 18 and the lower flange 19. The screw holes, bolts 20, and nuts 21 are all threaded connection components; bolts 20 and nuts 21 are screwed and installed between the upper flange 18 and the cutter head 1.

[0036] For a protective door at the cutting outlet of a tool magazine, a reinforcing rib 22 is integrally cast on the side of the connecting rod between the upper flange 18 and the lower flange 19. The reinforcing rib 22 is used to increase the strength of the installation component 3 and avoid the problem of fracture when supporting this device.

[0037] Working principle:

[0038] In the actual creation process of the present utility model, in order to avoid the following defects existing in the prior art: "The knife magazine outlet protection component in the prior art is mainly installed on the surface of the outlet in a fixed installation manner, and the protective cover is opened when a knife needs to be taken out to realize the output of the tool. The main defect of this protective door is that the adjustment method is single, and the tool can only move to a specific position to take out the knife, resulting in too long a knife-taking stroke for tools at different positions, thereby increasing the energy consumption of the device." The rotatable knife gate 2 and the installation component 3 are specifically proposed;

[0039] The tool disc 1 of the present device is the main part for placing tools, and the tool slots 5 provided inside the knife magazine 4 on its surface are the main parts for inserting tools. A gantry inner turntable 6 is rotatably provided around the periphery of the tool disc 1, and the outlet 7 provided between the inner turntables 6 is the part where the tool is output. In order to rotate relative to the inner turntable 6 inside to increase the speed of the tool running to the protective door 12, a wheel disc 9 is installed on one side of the tool disc 1, and a protective cover 11 is rotatably provided inside the rotating slot 10 inside the wheel disc 9. The protective cover 11 rotates inside the rotating slot 10 under the driving action of the friction wheel 17 on the side. When the inner turntables 6 on both the inner and outer sides and the protective cover 11 rotate simultaneously, the tool at a specific position will quickly reach the alignment position of the outlet 7 and the protective door 12 to take out the knife. We only need to control the rotation direction and angle of the inner turntable 6 and the protective cover 11 through a program. Note: The driving component of the inner turntable 6 is the motor 8, and the driving component of the protective cover 11 is the rotor 16.

[0040] To install and fix the present device, an upper flange 18 and a lower flange 19 are fixed at the bottom of the tool disc 1, and the upper flange 18 is fixed stably through bolts 20 and nuts 21. The reinforcing ribs 22 provided between the flanges are used to increase the structural strength and avoid the problem of deformation of the present device during use.
