[0090] Position detection element a7 is configured at the front end of the feeding guide rail 61, and position detection element c8 is configured at the rear end of the feeding guide rail 61. Both position detection elements a7 and c8 are used for position detection of the feeding slide 62. Specifically, the position of position detection element c8 on the feeding guide rail 61 is adjustable. For example, position detection element c8 includes a magnet and a Hall element. The magnet is magnetically attracted to the feeding guide rail 61, and the Hall element is fixedly installed on the feeding slide 62. By moving the position of the magnet, the feeding slide 62 can be adjusted to slide to the limit position at the right end of the feeding guide rail 61, which is convenient for adjustment according to the length of the long material 16 to save cutting time.

[0091] The cutting assembly 9 is disposed on one side of the frame 1. The cutting assembly 9 includes a fixedly disposed knife holder 91 (the upper surface of the knife holder 91 is V-shaped, and the V-shaped design facilitates the clamping of the long material 16. A guide wheel is disposed on the front side of the knife holder 91, and the guide wheel facilitates the transition of the front end of the long material 16 from the roller frame 3 to the knife holder 91). A cutting groove 911 is formed on the knife holder 91. The cutting assembly 9 also includes a high-speed rotating cutting blade 92 that moves closer to or away from the cutting groove 911, and a first clamping cylinder 93 and a second clamping cylinder 94 disposed on both sides of the cutting groove 911 for clamping the long material 16 to be cut.

[0092] The length-fixing component 10 is located on the other side of the cutting component 9 away from the feeding component 6. The length-fixing component 10 includes a length-fixing guide rail 101 and a length-fixing slider 102 locked on the length-fixing guide rail 101. A length-fixing cylinder 103 is provided on the length-fixing slider 102. A length-fixing rod 104 is provided at the shaft end of the length-fixing cylinder 103. After the position of the length-fixing slider 102 is locked, when the length-fixing cylinder 103 is extended, the straight distance between the length-fixing rod 104 and the feed groove 911 is the length of the material segment formed by cutting. A trigger switch (not shown in the figure) is provided at the free end of the length-fixing rod 104.

[0093] The adjusting slide rail 12 is located between the position detection element a7 and the position detection element c8. The position detection element b11 is slidably mounted on the adjusting slide rail 12. The position detection element b11 is used for position detection of the feeding slide table 62.

[0094] When position detection element a7 detects the feeding slide 62, the length of the portion of the feeding push rod 65 that crosses the infeed groove 911 is d. When position detection element b11 slides to the leftmost side of the adjusting slide rail 12, the distance between position detection element a7 and position detection element b11 is also d. In actual configuration, when position detection element a7 detects the feeding slide 62, the feeding push rod 65 and the tool holder 91 are kept flush on the left side. The distance from the infeed groove 911 to the left side of the tool holder 91 is set to d. When position detection element b11 slides to the leftmost side of the adjusting slide rail 12, the distance between position detection element a7 and position detection element b11 is also d.

[0095] The discharge hopper 13 is located between the fixed length component 10 and the cutting component 9. The discharge hopper 13 is equipped with a movable material plate 15 that is driven to flip by the hinge cylinder 14.

[0096] A buffer cylinder 64 is also provided on the feeding slide 62. The feeding push rod 65 is located on the cylinder shaft of the buffer cylinder 64. The air pressure in the buffer cylinder 64 is less than the air pressure in the fixed length cylinder 103 to ensure the accuracy of the cutting length. The adjustment slide 12 is marked with a scale, and the starting reading of the scale is d.

[0097] This automatic long material cutting machine is controlled by a PLC. It achieves complete automation, significantly improving work efficiency.

[0098] Example 5: Figure 6 As shown in the figure, a semi-automatic long material cutting machine according to an embodiment of the present invention is equipped with the cutting length adjustment device mentioned in the above embodiment 2. The feeding is semi-automatic, specifically fed by the feeding power wheel 17 on the rear side of the cutting assembly 9.

[0099] In practical use, for ease of understanding of this utility model, it will be described in conjunction with the accompanying drawings;

[0100] The complete working process of the automatic long material cutting machine involved in Example 4 is described as follows:

[0101] 1. Setting the length of the material segment: Slide the fixed length slider 102 on the fixed length guide rail 101. When the fixed length cylinder 103 is extended and the fixed length rod 104 is aligned with the knife holder 91, adjust the straight distance between the fixed length rod 104 and the infeed groove 911 to the set length of a single material segment, and lock the fixed length slider 102 to restrict its free sliding.

[0102] 2. Setting the length of the tail material: Move the position detection element b11 to the right on the adjustment slide rail 12. After moving, the reading of the scale is d1 (d1>d), which determines the length of the tail material as d1. When the remaining amount of tail material after multiple cuts of the actual long material 16 is less than or equal to d1, it can be automatically identified by the position detection element b11.

[0103] 3. Feeding: Multiple long materials 16 roll down in a single row and are intercepted at the abutment part 211. The feeding component 5 moves the bottom long material 16 over the abutment part 211 to the roller 4. Specifically, the feeding motor 52 makes the rotating shaft 51 rotate one revolution to achieve feeding.

[0104] 4. Feeding: The feeding motor 63 causes the feeding slide 62 to move to the left along the feeding guide rail 61, and the feeding push rod 65 pushes the long material 16 to the left.

[0105] 5. Cutting: When the left side of the long material 16 contacts the fixed-length rod 104, the trigger switch on the fixed-length rod 104 is turned on. The PLC receives the signal and controls the first clamping cylinder 93 and the second clamping cylinder 94 to clamp the long material 16 on both sides of the feed groove 911. After one end of the long material 16 is clamped, the fixed-length cylinder 103 moves to retract the fixed-length rod 104 and reset it. The cutting blade 92 enters the feed groove 911 to perform cutting. After cutting is completed, the cutting blade 92 exits the feed groove 911, and the first clamping cylinder 93 and the second clamping cylinder 94 reset and release the long material 16. The cut material falls due to its own weight and is collected in the collection box through the discharge hopper 13. The fixed-length cylinder 103 moves to extend the fixed-length rod 104 again. This process is repeated multiple times.

[0106] 6. Tail Material Removal: As the feeding motor 63 continuously moves the feeding slide 62 to the left along the feeding guide rail 61, the position detection element b11 detects the feeding slide 62. The remaining tail material does not need to be cut. The PLC receives the signal and controls the fixed-length cylinder 103 to retract and create space. Simultaneously, it controls the hinge cylinder 14 to rotate the movable material plate 15 (see...). Figure 5As the feeding slide 62 continues to move to the left, the feeding push rod 65 pushes the tail material into the discharge hopper 13. At this time, because the movable material plate 15 is in a flipped state, the tail material cannot enter the collection box, thus achieving the removal of the tail material. After the tail material is removed, the hinge cylinder 14 resets, causing the movable material plate 15 to return to its original state.

[0107] 7. Cyclic Process: When the position detection element a7 detects the feeding slide 62, the feeding slide 62 reaches the leftmost position. The feeding push rod 65 and the knife holder 91 remain flush on the left side. The PLC receives this signal and controls the feeding motor 63 to rotate in the opposite direction, that is, the feeding slide 62 begins to move to the right until the position detection element c8 detects the feeding slide 62. The feeding slide 62 reaches the rightmost position, and the PLC receives this signal and controls the feeding slide 62 to move to the left. With the feeding component 5 feeding again, the automatic cyclic operation of the whole machine is realized.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
