Description

Technical Field

[0001] The present invention relates to the technical field of cutting flexible materials, and in particular to an intelligent cutting machine head. Background Art

[0002] In the production process of flexible materials such as leather, the cutting of materials is generally done by manually laying out the pattern on the material, and then cutting it with a die through a hydraulic cutting machine. This traditional production method is not only costly but also has low cutting efficiency because the die must be made separately for each part of the material.

[0003] In order to solve the above problems, the Chinese patent "Leather Cutting Machine" (application number: CN200810098051.7) with authorization announcement number CN101586171B discloses a structure, which includes a base frame and a workbench arranged on the base frame, a moving beam is arranged above the workbench, a cutter head assembly that can move along the moving beam is arranged on the moving beam, and a projection frame is fixed to the base or the workbench, and a projection assembly is arranged on the projection frame. This structure can project the sample to be cut onto the workbench through the projection assembly, and use the cutter assembly arranged on the moving beam to cut the leather placed on the surface of the workbench. Although the above structure realizes the cutting of materials with different layouts, due to the single structure of its cutter head assembly, when the cutting of a material requires cutter head assemblies with different functions, it is still necessary to continuously replace the cutter head assembly to meet the requirements. This brings great inconvenience to production and reduces production efficiency to a great extent.

[0004] Therefore, the current structure of the cutting machine for flexible materials needs to be further improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an intelligent cutting machine head which can be equipped with cutter head assemblies with different functions and can select the cutting head assembly according to the needs so as to improve the cutting efficiency in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an intelligent cutting machine head, including a base, characterized in that it also includes a first mounting seat, a second mounting seat, a first cutter head assembly, a second cutter head assembly, a camera and a pen, the first mounting seat can be movably arranged on the base up and down, the second mounting seat can be movably arranged on the base up and down and is arranged close to the first mounting seat, the first cutter head assembly can be rotatably arranged on the first mounting seat, the second cutter head assembly can be rotatably arranged on the second mounting seat, the camera is arranged on the base and is used to collect information on the surface of the material to be cut, and the pen can be movably arranged on the base up and down and is located between the first mounting seat and the second mounting seat.

[0007] To facilitate assembly, the first mounting seat and the second mounting seat have the same structure and both include a base sleeve, a mounting sleeve and a locking ring. The base sleeve can be movably arranged on the base up and down, the mounting sleeve is sleeved in the base sleeve and the upper end is exposed at the top of the base sleeve, the mounting sleeve has an assembly cavity for inserting the first cutter head assembly / the second cutter head assembly therein, and a radially extending clamping block is provided on the outer peripheral wall of the top of the first cutter head assembly / the second cutter head assembly, and correspondingly, a limiting opening is provided on the top edge of the mounting sleeve for the clamping block to be clamped therein so as to circumferentially limit the first cutter head assembly / the second cutter head assembly, and the locking ring is sleeved on the top of the mounting sleeve and is used to lock the first cutter head assembly / the second cutter head assembly.

[0008] Preferably, a transmission ring is provided on the top of the base sleeve and is sleeved on the outer circumference of the mounting sleeve. A first motor is provided on the base. A transmission wheel is connected to the output shaft of the first motor. The transmission wheel and the transmission ring are connected by a transmission belt. The base sleeve can be moved up and down on the base through the matching structure of a slide rail and a slider. A second motor that can drive the slider to move back and forth along the slide rail is provided on the base, and the first motor moves synchronously with the second motor.

[0009] As a preferred solution, the first cutter head assembly is a cutter head assembly that can drive the blade to vibrate up and down, and the second cutter head assembly is a cutter head assembly with a half-cut function. This structure can switch between the up and down vibration cutting and the half-cut function to meet production needs.

[0010] As another preferred solution, the first cutter head assembly is a cutter head assembly that can drive the blade to vibrate up and down, and the second cutter head assembly is a cutter head assembly that can automatically fine-tune the cutting depth. This structure can switch between up and down vibration cutting and normal cutting functions to meet production needs.

[0011] In the above scheme, the first cutter head assembly includes a first sleeve, a core shaft and a first blade, the first sleeve is through-through, the core shaft is arranged in the inner cavity of the first sleeve so as to be able to vibrate up and down, the first blade is arranged at the lower end of the core shaft and exposed at the lower end of the first sleeve, and further includes

[0012] A mounting box is rotatably arranged on the top of the first sleeve relative to the core shaft, and the interior of the mounting box is hollow to form a mounting inner cavity;

[0013] A third motor is arranged outside the installation box and its output shaft extends transversely into the installation box and is arranged perpendicular to the core shaft;

[0014] An eccentric sleeve is arranged in the installation inner cavity of the installation box, is sleeved on the outer periphery of the output shaft of the third motor and rotates synchronously with the output shaft of the third motor;

[0015] A transmission sleeve is rotatably arranged on the outer periphery of the eccentric sleeve, and a connecting arm extending downward is arranged on the outer peripheral wall of the lower part of the transmission sleeve; and

[0016] A transmission cap, the upper end of which is connected to the connecting arm of the transmission sleeve through a connecting rod, and the lower end of which is rotatably connected to the upper end of the core shaft.

[0017] The above structure uses a motor to provide the power for the core shaft to vibrate up and down, and uses the matching structure of the eccentric sleeve, connecting rod and transmission cap to convert the lateral rotational force into the force of the core shaft to vibrate up and down. On the premise of simplifying the vibration structure, the motor load is reduced, energy consumption is saved, and production costs are reduced. At the same time, when the core shaft vibrates up and down, the rotational inertia of the eccentric sleeve can be used for continuous operation, which is beneficial to improving the stability of the cutter head and the cutting accuracy.

[0018] Preferably, the eccentric sleeve is vertically arranged on the front of the first disc, a second disc parallel to the first disc and eccentrically arranged is arranged on the back of the first disc, the eccentric direction of the first disc and the second disc is opposite to the eccentric direction of the eccentric sleeve, a concentric sleeve is arranged on the back of the second disc, and the output shaft of the third motor passes through the eccentric sleeve, the first disc, the second disc and the concentric sleeve in sequence. Such a structure is conducive to using the inertia of the rotation of the first disc and the second disc to provide power for the transmission sleeve, thereby reducing the motor load and saving energy consumption.

[0019] Furthermore, the eccentricity of the first disc and the second disc is greater than the eccentricity of the eccentric sleeve. This structure is beneficial to further reduce the motor load.

[0020] In the above scheme, the second cutter head assembly includes a second sleeve, a mounting rod and a second blade, the second sleeve is through-through from top to bottom, the mounting rod is arranged at the lower part of the inner cavity of the second sleeve, the second blade is arranged at the lower end of the mounting rod and exposed at the lower end of the second sleeve, and also includes a first adjusting rod, an adjusting sleeve and a first elastic member, the adjusting sleeve is adjustably arranged at the upper part of the second sleeve, the upper part of the first adjusting rod can be movably arranged in the adjusting sleeve up and down, the lower end of the first adjusting rod is exposed at the lower end of the adjusting sleeve and is connected to the upper end of the mounting rod, and the first elastic member enables the first adjusting rod to always maintain a tendency to move downward; a first mounting sleeve is arranged in the inner cavity of the upper part of the second sleeve, an internal thread is arranged on the inner wall of the first mounting sleeve, and correspondingly, an external thread is arranged on the outer wall of the adjusting sleeve, and the adjusting sleeve is connected to the first mounting sleeve by threading; the upper end of the adjusting sleeve is exposed outside the upper end of the second sleeve and is formed with an adjustment portion that enables the adjusting sleeve to rotate relative to the first mounting sleeve to adjust the height of the adjusting sleeve. With the above structure, when the half-cut depth is set for cutting, if there is a slight fluctuation in the processing platform, the mounting rod will compress the elastic part upward under the top action of the processing platform, or the blade will move downward under the elasticity of the elastic part, so that the blade always maintains the same cutting depth for the material to be cut, thereby improving the cutting accuracy.

[0021] In the above scheme, the second cutter head assembly includes a third sleeve, a mounting member and a third blade. The third sleeve is through-through, the mounting member is arranged at the lower part of the inner cavity of the third sleeve, the third blade is arranged at the lower end of the mounting member and exposed at the lower end of the third sleeve, and also includes a second adjustment rod. The mounting member can be slidably arranged in the third sleeve up and down, the second adjustment rod is arranged in the third sleeve and the lower end is threadedly connected to the upper end of the mounting member, and the upper end of the second adjustment rod is exposed at the upper end of the third sleeve and can be rotatably constrained on the third sleeve. With the above structure, when the height of the blade needs to be adjusted during the operation of the machine, there is no need to stop the operation of the entire machine. It is only necessary to pause the cutting action of the cutter head and rotate the adjustment rod to fine-tune the height of the blade. The operation is simple and convenient.

[0022] Compared with the prior art, the advantages of the present invention are: the present invention can install the first blade head assembly and the second blade head assembly with different functions on the first mounting seat and the second mounting seat respectively to meet different cutting needs. When in use, the surface information of the material to be cut can be collected by the camera at any time, and the pen can be lowered to make marks or patterns on the material as needed, and then the first blade head assembly and the second blade head assembly can be alternately selected for cutting, thereby improving the cutting efficiency.

[0043] The intelligent cutting machine head and the corresponding entire machine of this embodiment are controlled by the same controller, the camera 6 is communicated with the controller, and the up and down movement of the pen 7 is also uniformly controlled by the controller. The pen 7 can be moved up and down on the base through a linear motor or other existing mechanical structure, which will not be elaborated here.

[0044] The first mounting seat 2 and the second mounting seat 3 of this embodiment have the same structure, and both include a base sleeve 21, a mounting sleeve 22 and a locking ring 23. The base sleeve 21 can be movably arranged on the base 1 up and down, and the mounting sleeve 22 can be rotatably sleeved in the base sleeve 21 through a bearing 210 and the upper end is exposed at the top of the base sleeve 21. The mounting sleeve 22 has an assembly cavity 220 for the first cutter head assembly 4 / the second cutter head assembly 5 to be inserted therein, and a radially extending clamping block 41 is provided on the outer peripheral wall of the top of the first cutter head assembly 4 / the second cutter head assembly 5. Correspondingly, a limiting opening 221 is provided on the top edge of the mounting sleeve 22 for the clamping block 41 to be clamped therein so as to circumferentially limit the first cutter head assembly 4 / the second cutter head assembly 5, and the locking ring 23 is sleeved on the top of the mounting sleeve 22 and is used to lock the first cutter head assembly 4 / the second cutter head assembly 5. A transmission ring 24 is provided on the top of the base sleeve 21 and is sleeved on the outer periphery of the mounting sleeve 22. A first motor 8 is provided on the base 1. A transmission wheel 81 is connected to the output shaft of the first motor 8. The transmission wheel 81 is connected to the transmission ring 24 through a transmission belt 25 to drive the mounting sleeve 22 and then drive the first cutter head assembly 4 / second cutter head assembly 5 to move up and down. The base sleeve 21 is provided on the base 1 so as to be movable up and down through the matching structure of the slide rail and the slider. A second motor 9 is provided on the base 1 to drive the slider to move back and forth along the slide rail. The first motor 8 moves synchronously with the second motor 9. This structure is used to drive the first cutter head assembly 4 / second cutter head assembly 5 to move up and down.

[0045] The first cutter head assembly 4 of the present embodiment comprises a first sleeve 1a, a mandrel 2a, a first blade 3a, a mounting box 4a, a third motor 5a, an eccentric sleeve 6a, a transmission sleeve 7a and a transmission cap 8a. The first sleeve 1a is through-through, the mandrel 2a is arranged in the inner cavity of the first sleeve 1a so as to vibrate up and down, the first blade 3a is arranged at the lower end of the mandrel 2a and exposed at the lower end of the first sleeve 1a. The mounting box 4a is rotatably arranged at the top of the first sleeve 1a relative to the mandrel 2a, and the interior of the mounting box 4a is hollow to form an installation cavity 40a. The third motor 5a is arranged outside the mounting box 4a, and the output shaft 51a of the third motor 5a can be rotatably extended into the installation cavity 40a of the mounting box 4a, and the output shaft 51a is arranged perpendicular to the mandrel 2a. The eccentric sleeve 6a is arranged in the installation inner cavity 40a of the installation box 4a, and the eccentric sleeve 6a is sleeved on the outer periphery of the output shaft 51a of the third motor 5a and rotates synchronously with the output shaft 51a of the third motor 5a. The transmission sleeve 7a is rotatably arranged on the outer periphery of the eccentric sleeve 6a, and a connecting arm 71a extending downward is arranged on the outer peripheral wall of the lower part of the transmission sleeve 7a; the upper end of the transmission cap 8a is connected to the connecting arm 71a of the transmission sleeve 7a through the connecting rod 9a, and the lower end of the transmission cap 8a is rotatably connected to the upper end of the core shaft 2a.

[0046] Specifically, the eccentric sleeve 6a is vertically arranged on the front of the first disc 61a, and the back of the first disc 61a is provided with a second disc 62a which is parallel to the first disc 61a and eccentrically arranged. The eccentric direction of the first disc 61a and the second disc 62a is opposite to the eccentric direction of the eccentric sleeve 6a, and the back of the second disc 62a is provided with a concentric sleeve 63a. The output shaft 51a of the third motor 5a passes through the eccentric sleeve 6a, the first disc 61a, the second disc 62a and the concentric sleeve 63a in sequence. The eccentricity of the first disc 61a and the second disc 62a is greater than the eccentricity of the eccentric sleeve 6a. This structure is conducive to using the inertia of the rotation of the first disc 61a and the second disc 62a to provide power for the transmission sleeve 7a, thereby reducing the load of the third motor and saving energy consumption. The outer circumferential walls of the first disc 61a and the second disc 62a are provided with mounting holes 64a through which bolts or other locking structures can pass and abut against the output shaft 51a of the third motor 5a so that the eccentric sleeve 6a rotates synchronously with the output shaft 51a of the third motor 5a. A rotating bearing 65a is provided between the transmission sleeve 7a and the eccentric sleeve 6a to reduce friction and the load of the third motor.

[0047] The transmission cap 8a of this embodiment is formed with a receiving chamber 80a at the lower part, and the upper end of the mandrel 2a is rotatably arranged in the receiving chamber 80a through the first bearing assembly 21a. A mounting sleeve 11a extending along the length direction of the first sleeve 1a is arranged in the first sleeve 1a, and the mounting sleeve 11a is fixed on the inner wall of the first sleeve 1a by bolts, and the mounting sleeve 11a and the first sleeve 1a always remain relatively stationary. The mandrel 2a can move up and down through the mounting sleeve 11a, and an installation gap 10a is formed between the outer peripheral wall of the upper part of the mounting sleeve 11a and the inner peripheral wall of the first sleeve 1a. The lower end of the mounting box 4a has a plug-in portion 41a that can be inserted into the installation gap 10a, and the plug-in portion 41a is rotatably connected to the mounting sleeve 11a through the second bearing assembly 111a. Since the cutter head as a whole often needs to rotate in the circumferential direction during use, this structure provides conditions for realizing the above functions.

[0048] The inner cavity at the lower part of the first sleeve 1a is provided with a first assembly sleeve 12a arranged near the lower port, and the side wall of the first assembly sleeve 12a is symmetrically provided with a guide groove 121a extending in the axial direction, and the outer periphery of the lower end of the mandrel 2a is sleeved with a second assembly sleeve 13a, and the side wall of the second assembly sleeve 13a extends outward to form a guide block 131a that can cooperate with the guide groove 121a. Since the mandrel 2a is long, it is easy to shake during the up and down vibration process. The above structure is used to limit the lower end of the mandrel 2a, and at the same time play a guiding role in the up and down movement, which can improve the cutting stability of the first blade and improve the cutting accuracy. The side wall of the center hole 130a of the second assembly sleeve 13a extends to one side to form an assembly hole 132a for installing the first blade 3a.

[0049] The cutting machine head of this embodiment also includes a protective sleeve 100a and an elastic member 101a. The protective sleeve 100a can be moved up and down to cover the lower end of the first sleeve 1a. The bottom of the protective sleeve 100a is provided with an opening 102a for the first blade 3a to be exposed. The elastic member 101a can keep the protective sleeve 100a moving downward all the time, so as to hide the lower end of the first blade 3a in the protective sleeve 100a. During use, the workpiece to be cut presses against the lower surface of the protective sleeve, and the protective sleeve 100a overcomes the elastic force of the elastic member 101a and moves upward. At this time, the first blade 3a is exposed from the opening 102a and can cut the workpiece; when not in use, the protective sleeve 100a moves downward under the action of the elastic member 101a to hide the first blade 3a therein, playing a protective role, on the one hand protecting the first blade 3aa, on the other hand preventing workers from being accidentally injured. A first step 103a is formed on the outer circumferential wall of the protective sleeve 100a, and correspondingly, a second step 104a is formed on the outer circumferential wall of the lower part of the first sleeve 1a. The elastic member 6a is a spring sleeved on the outer circumference of the first sleeve 1a and the protective sleeve 100a, and the first end of the spring abuts against the first step 103, and the second end of the spring abuts against the second step 104a.

[0050] When the cutting machine head with a vibration function of the present embodiment is used, the output shaft 51a of the third motor rotates to drive the eccentric sleeve 6a to rotate synchronously, and then drives the transmission sleeve 7a to float up and down through the rotating bearing 65a. The transmission sleeve 7a drives the transmission cap 8a to move up and down through the connecting rod 9a, and then drives the core shaft 2a of the first blade 3a of the mounting shaft to vibrate up and down. In this process, since the eccentric direction of the first disk 61a and the second disk 62a is opposite to the eccentric direction of the eccentric sleeve 6a, and the eccentricity of the first disk 61a and the second disk 62a is greater than the eccentricity of the eccentric sleeve 6a, the imbalance of the overall structure can be used to better exert the rotational inertia of the first disk 61a and the second disk 62a, thereby reducing the load of the third motor and saving energy.

[0051] The second blade assembly 5 of this embodiment includes a second sleeve 1b, a mounting rod 2b, a third blade 3b, a first adjustment rod 4b, an adjustment sleeve 5b and a first elastic member 6b. The second sleeve 1b is through-connected from top to bottom. The mounting rod 2b is arranged at the lower part of the inner cavity of the second sleeve 1b. The third blade 3b is arranged at the lower end of the mounting rod 2b and exposed at the lower end of the second sleeve 1b. The adjustment sleeve 5b is arranged at the upper part of the second sleeve 1b in an adjustable manner. The upper part of the first adjustment rod 4b is arranged in the adjustment sleeve 5b in an adjustable manner. The lower end of the first adjustment rod 4b is exposed at the lower end of the adjustment sleeve 5b and is connected to the upper end of the mounting rod 2b. The first elastic member 6b makes the first adjustment rod 4b always maintain a downward movement trend.

[0052] Specifically, a third assembly sleeve 7b is provided in the inner cavity at the upper part of the second sleeve 1b, and the third assembly sleeve 7b is positioned in the second sleeve 1b by threaded connection, and does not move relative to the second sleeve 1b. An internal thread is provided on the inner wall of the third assembly sleeve 7b, and correspondingly, an external thread is provided on the outer wall of the adjustment sleeve 5b, and the adjustment sleeve 5b is connected to the third assembly sleeve 7b by threaded connection. The above structure can realize the up and down adjustment of the third assembly sleeve 7b relative to the second sleeve 1b, thereby adjusting the cutting depth of the cutter head. The structure also cooperates with the structure of the first adjustment rod 4b and the first elastic member 6b to realize floating compensation for the cutting depth of the cutter head, thereby improving the cutting accuracy.

[0053] In this embodiment, the upper end of the adjusting sleeve 5b is exposed outside the upper port of the second sleeve 1b and is formed with a mediation portion 51b that can make the adjusting sleeve 5b rotate relative to the third assembly sleeve 7b to adjust the height of the adjusting sleeve 5b. With this structure, when adjusting the cutting depth, there is no need to stop the entire machine and remove the cutter head as a whole for adjustment. It is only necessary to pause the machine to adjust it, which is convenient to use. In order to make the first adjusting rod 4b move up and down smoothly, the adjusting sleeve 5b is hollow inside to form a guide channel 50b extending up and down, and the upper part of the first adjusting rod 4b can be moved up and down in the guide channel 50b. In order to facilitate assembly, the diameter of the lower part of the guide channel 50b is gradually enlarged to form a first step 501b, and correspondingly, a second step 41b is formed on the outer peripheral wall of the lower part of the first adjusting rod 4b. The first elastic member 6b is a spring sleeved outside the first adjusting rod 4b, and the first end of the spring is against the first step 501b, and the second end of the spring is against the second step 41b.

[0054] In the inner cavity of the lower part of the second sleeve 1b of this embodiment, a fourth assembly sleeve 8b is provided, and a shaft sleeve 9b capable of guiding and cooperating with the installation rod 2b is provided in the fourth assembly sleeve 8b. The installation rod 2b is arranged through the fourth assembly sleeve 8b and the shaft sleeve 9b, and the lower end of the installation rod 2b is exposed at the lower port of the second sleeve 1b. The fourth assembly sleeve 8b is fixed to the second sleeve 1b by a bolt 81b to prevent the fourth assembly sleeve 8b from moving in the second sleeve 1b. A guide groove 82b extending axially is provided on the upper part of the fourth assembly sleeve 8b, and an axle pin 21b arranged perpendicular to the installation rod 2b and capable of guiding and cooperating with the guide groove 82b up and down is provided on the installation rod 2b. A roller 22b capable of reducing friction is provided on the outer periphery of the axle pin 21b. The above structure enables the installation rod 2b to move up and down smoothly to improve the floating compensation accuracy. To facilitate assembly, the lower end of the first adjusting rod 4b is connected to the upper end of the mounting rod 2b via an assembly column 10b, and a first socket is downwardly opened on the upper end surface of the assembly column 10b for inserting the lower end of the first adjusting rod 4b therein, and a second socket is upwardly opened on the lower end surface of the assembly column 10b for inserting the upper end of the mounting rod 2b therein, and a screw 200b is inserted from the first socket into the second socket and connected to the upper end of the mounting rod 2b, so that the mounting rod 2b can maintain synchronous movement with the assembly column 10b.

[0055] When using the cutting machine head with the half-cutting function of this embodiment, the half-cutting depth is first determined by setting the height of the adjusting sleeve 5b in the second sleeve 1b. When cutting, if there is a slight fluctuation on the processing platform, the mounting rod 2b compresses the first elastic member 6b upward under the top action of the processing platform, or the third blade 3b moves downward under the elasticity of the first elastic member 6b, so that the third blade 3b always maintains the same cutting depth for the material to be cut, thereby improving the cutting accuracy.

[0056] Embodiment 2:

[0057] The difference between this embodiment and embodiment 1 is that: Figures 15 to 17 As shown, the structure of the second blade assembly in this embodiment is different from that in the first embodiment. The second blade assembly 5' in this embodiment includes a third sleeve 1c, a mounting member 2c, a third blade 3c, a second adjustment rod 4c, a first protective sleeve 5c and a second elastic member 6c. The third sleeve 1c is through-through from top to bottom. The mounting member 2c is arranged at the lower part of the inner cavity of the third sleeve 1c. The third blade 3c is arranged at the lower end of the mounting member 2c and exposed at the lower end of the third sleeve 1c. The mounting member 2c is arranged in the third sleeve 1c so as to be able to slide up and down. The second adjustment rod 4c is arranged in the third sleeve 1c and the lower end is threadedly connected to the upper end of the mounting member 2c. The upper end of the second adjustment rod 4c is exposed at the upper end of the third sleeve 1c and can be rotatably constrained on the third sleeve 1c. The upper end of the second adjustment rod 4c is designed with an adjustment port 41c for easy adjustment with a tool.

[0058] In this embodiment, the middle part of the mounting member 2c is provided with a first limiting groove 21c extending in the axial direction, and the inner wall of the third sleeve 1c is provided with a first limiting column 11c inserted in the first limiting groove 21c and capable of respectively cooperating with the upper and lower side walls of the first limiting groove 21c to limit the position of the mounting member 2c. The first limiting column 11c is detachably inserted in the third sleeve 1c for easy assembly and disassembly maintenance. This structure can prevent the second adjustment rod 4c from being over-adjusted, causing the mounting member 2c to be separated from the third sleeve 1c and thus affecting the use. The upper part of the mounting member 2c is provided with a second limiting groove 22c extending in the axial direction, and the inner wall of the third sleeve 1c is provided with a second limiting column 12c that can be inserted in the second limiting groove 22c and can cooperate with the side wall of the second limiting groove 22c to limit the circumferential rotation of the mounting member 2c. The second limiting column 12c is detachably inserted in the third sleeve 1c for easy assembly and disassembly maintenance. On the one hand, this structure can prevent the mounting member 2c from moving circumferentially and affecting the adjustment of the second adjustment rod 4c. On the other hand, it can also play a guiding role, so that the mounting member 2c can move up and down smoothly during the adjustment process. In order to facilitate operation, a mounting sleeve 13c is provided in the upper end of the third sleeve 1c, and a mounting hole 131c is opened in the middle of the mounting sleeve 13c for the second adjustment rod 4c to pass through. The lower surface of the mounting sleeve 13c is provided with a locking ring 14c that is sleeved on the outer periphery of the second adjustment rod 4c and abuts against the lower surface of the mounting sleeve 13c to prevent the second adjustment rod 4c from rotating in a non-human operation state. The upper surface of the above-mentioned mounting sleeve 13c can also be printed with a rotation direction mark for indicating the adjustment height.

[0059] To facilitate installation, the lower side of the mounting member 2c of this embodiment is recessed inward to form a vertically arranged mounting surface 20c, and a locking block 201c is provided on the outer side of the mounting surface 20c for clamping the third blade 3c with the mounting surface 20c. The locking block 201c is detachably fixed to the mounting surface 20c by screws 100c.

[0060] The first protective sleeve 5c of this embodiment can be moved up and down to cover the lower end of the third sleeve 1c. The bottom of the first protective sleeve 5c is provided with an opening 51c for exposing the third blade 3c. The second elastic member 6c can keep the first protective sleeve 5c moving downward all the time, thereby hiding the lower end of the third blade 3c in the first protective sleeve 5c. During use, the workpiece being cut presses against the lower surface of the first protective sleeve 5c, and the first protective sleeve 5c overcomes the elastic force of the second elastic member 6c and moves upward. At this time, the third blade 3c is exposed from the opening 51c and can cut the workpiece; when not in use, the first protective sleeve 5c moves downward under the action of the second elastic member 6c to hide the third blade 3c therein, playing a protective role, on the one hand protecting the third blade 3c, on the other hand preventing workers from being accidentally injured. A first step 52c is formed on the outer peripheral wall of the first protective sleeve 5c, and correspondingly, a second step 15c is formed on the outer peripheral wall of the lower part of the third sleeve 1c. The second elastic member 6c is a spring sleeved on the outer periphery of the third sleeve 1c and the first protective sleeve 5c, and the first end of the spring abuts against the first step 52c, and the second end of the spring abuts against the second step 15.

[0061] When the cutting machine head with the fine-tuning function of the present embodiment needs to adjust the height of the third blade 3c during the operation of the machine, there is no need to stop the operation of the entire machine. Instead, the cutting action of the cutting head needs to be paused, and the height of the third blade 3c can be fine-tuned by rotating the second adjustment rod 4c. The operation is simple and easy to use.
