Detailed Implementation

[0039] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0040] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0041] like Figures 1 to 5 As shown, this solution provides an automatic cutting head device for cutting off the material head 2 from a workpiece 1. The automatic cutting head 2 device includes: a machine base 3, on which a rotating disk 4 is mounted, and the workpiece 1 and the material head 2 on it are placed on the rotating disk 4; a cutting unit 5, which has a first pressing block 6, a second pressing block 7, and a cutting component 8. The first pressing block 6 is movably mounted above the rotating disk 4 and movably abuts against the workpiece 1 to fix the workpiece 1; the second pressing block 7 is movably mounted on the machine base 3 and movably abuts against the material head 2 on the workpiece 1 to fix the material head 2; the cutting component 8 is movably mounted on the machine base 3 to cut the material head 2; and a rejection unit 9, which is mounted on the machine base 3 to reject the cut material head 2 from the rotating disk 4.

[0042] During operation, the workpiece 1 to be processed is placed on the rotating disk 4, which transports the workpiece 1 to the cutting unit 5. The first pressing block 6 contacts the workpiece 1 and applies pressure, fixing the main body of the workpiece 1. Subsequently, the second pressing block 7 contacts the material head 2 and applies pressure, fixing the material head 2. After fixing, the cutting component 8 precisely cuts the connection between the workpiece 1 and the material head 2, separating the workpiece 1 and the material head 2, but the material head 2 still remains on the rotating disk 4. After cutting, the rotating disk 4 transports the workpiece 1 and the cut material head 2 to the rejection unit 9. The rejection unit 9 is activated to remove the separated material head 2 from the rotating disk 4. Finally, the rotating disk 4 continues to transport the workpiece 1, which has been cut, to the preset position. Through the above process, this solution realizes fully automated operation from fixing and cutting the workpiece 1 and the material head 2 to rejection, effectively improving production efficiency, reducing manual intervention, and ensuring the consistency and stability of product quality.

[0043] Furthermore, the cutting unit 5 also includes: a support base 10, which is disposed on the machine base 3; a first driving member 11 is disposed on the support base 10, and a first pressure block 6 is connected to the output end of the first driving member 11. The first driving member 11 is used to drive the first pressure block 6 to move up and down in the vertical direction.

[0044] Furthermore, the cutting unit 5 also includes: a support frame 12, on which the second pressing block 7 is connected; a second driving member 13, whose output end is connected to the support frame 12, the second driving member 13 drives the second pressing block 7 to move vertically through the support frame 12; and a third driving member 14, which is disposed on the support frame 12, the cutting member 8 being connected to the output end of the third driving member 14, the third driving member 14 being used to drive the cutting member 8 to move vertically.

[0045] Furthermore, the cutting unit 5 also includes: a fixed plate 15, which is disposed on the machine base 3; a movable seat 16, which is movably disposed on the fixed plate 15, and the second driving member 13 and the support frame 12 are both disposed on the movable seat 16; and a fourth driving member 17, which is disposed on the fixed plate 15, and the output end of the fourth driving member 17 is connected to the movable seat 16 for driving the movable seat 16 to move closer to or away from the rotating disk 4.

[0046] When the rotating disk 4 transports the workpiece 1 to be processed to the position of the cutting unit 5, firstly, the first pressure block 6 descends vertically under the drive of the first driving member 11 until it contacts the upper surface of the workpiece 1 and applies a certain pressure, thereby clamping and fixing the main body of the workpiece 1; at the same time, the fourth driving member 17 is activated, driving the moving seat 16 to approach the rotating disk 4 horizontally until the moving seat 16 moves to the preset position; then, the second driving member 13 drives the second pressure block 7 to descend vertically through the support frame 12 until the second pressure block 7 contacts the material head 2 and applies a certain pressure, thereby clamping and fixing the material head 2; at this time, the third driving member 14 and the cutting member 8 descend synchronously with the support frame 12 to the cutting start position; after the workpiece 1 and the material head 2 are reliably fixed, the third driving member 14 is activated, driving the cutting member 8 to move upward vertically, thereby clamping and fixing the connection between the workpiece 1 and the material head 2. The joint is precisely cut; after the cut is completed, the third drive 14 drives the cutting part 8 to descend vertically back to the starting position of the cut; then, the second drive 13 drives the second pressure block 7 to rise and reset through the support frame 12, releasing the pressure on the material head 2; at the same time, the third drive 14 and the cutting part 8 are driven by the support frame 12 back to the initial position on the moving seat 16; the fourth drive 17 drives the moving seat 16 to reset horizontally away from the rotating disk 4; finally, the first drive 11 drives the first pressure block 6 to rise, releasing the pressure on the workpiece 1, waiting for the next cycle operation; at this point, a complete cutting cycle is completed, and the rotating disk 4 continues to transport the workpiece 1 that has completed the cutting operation to the location of the rejection unit 9; wherein, the cutting part 8 is preferably a cutter, and the first drive 11, the second drive 13, the third drive 14 and the fourth drive 17 can all be motors, hydraulic cylinders or pneumatic cylinders.

[0047] To enable the sliding guide function of the movable seat 16 on the fixed plate 15, the fixed plate 15 is provided with a slide rail 18, and a slider 19 is installed at the bottom of the movable seat 16. The slider 19 slides with the slide rail 18, so that the movable seat 16 can be smoothly slidably set on the slide rail 18 along its extension direction. The arrangement of the slide rail 18 and the slider 19 not only improves the stability and accuracy of the movable seat 16 during movement, but also effectively prevents jamming or malfunction caused by offset, thereby ensuring the reliability and consistency of the cutting action.

[0048] Furthermore, a processing station 20 is provided on the circumference of the rotating disk 4; the processing station 20 is provided with a positioning groove 21 and a positioning block 22, and a hollow part 23 is provided between the positioning groove 21 and the positioning block 22; when the workpiece 1 to be processed is placed on the rotating disk 4, the main body of the workpiece 1 is placed on the positioning groove 21, and the material head 2 on the workpiece 1 is placed on the positioning block 22, and the connection part between the workpiece 1 and the material head 2 is located directly above the hollow part 23, thereby realizing the precise positioning of the workpiece 1 and the material head 2 on the processing station 20, ensuring that the relative position of the main body of the workpiece 1 and the material head 2 is stable and reliable during the cutting process, and improving the processing consistency; when cutting the connection part between the workpiece 1 and the material head 2, the cutting part 8 moves upward in the vertical direction under the drive of the third driving part 14 and passes through the hollow part 23 to cut the connection part between the workpiece 1 and the material head 2.

[0049] Furthermore, the rejection unit 9 includes: a rejection member 24, which is movably mounted on the machine base 3 for rejecting the material head 2; a collection member 25, which is mounted on the side of the rotating disk 4 for receiving the material head 2 pushed out by the rejection member 24; and a fifth driving member 26, which is mounted on one side of the collection member 25 and located below the rotating disk 4. The rejection member 24 is connected to the output end of the fifth driving member 26, and the fifth driving member 26 is used to drive the rejection member 24 to move in the vertical direction.

[0050] During operation, when workpiece 1, along with the cut-off head 2, is moved by the rotating disk 4 to the position of the rejection unit 9, the fifth drive component 26 is activated, driving the rejection component 24 to move vertically upwards and pass through the hollowed-out portion 23 on the processing station 20. The top of the rejection component 24 contacts and pushes the head 2, lifting it off the positioning block 22 and pushing it out, causing the head 2 to leave the processing station 20. Subsequently, the head 2 falls into the collecting component 25 located on the side of the rotating disk 4 under the action of gravity, completing the entire rejection and collection process. This design not only achieves efficient removal of the head 2 but also avoids manual intervention, improving the automation level and operating efficiency of the entire machine. Through the coordinated design of the rejection component 24 and the collecting component 25, the rejection unit 9 can stably and reliably complete the automatic rejection of the head 2, thereby improving the continuity and stability of the entire production line.
