[0089] The position detection element a7 is arranged at the front end of the feed guide rail 61, and the position detection element c8 is arranged at the rear end of the feed guide rail 61. Both the position detection element a7 and the position detection element c8 are used to detect the position of the feed slide 62. Specifically, the position of the position detection element c8 on the feed guide rail 61 is adjustable. For example, the position detection element c8 includes a magnet and a Hall element. The magnet is adsorbed on the feed guide rail 61 by magnetic attraction, and the Hall element is fixedly mounted on the feed slide 62. In this way, by moving the position of the magnet, the feed slide 62 can be adjusted to slide to the extreme position of the right end of the feed guide rail 61, which is convenient for adjustment according to the length of the long material 16 to save cutting time.

[0090] The cutting assembly 9 is arranged on one side of the frame 1 and includes a fixed knife seat 91 (the upper surface of the knife seat 91 is V-shaped, and the V-shaped design facilitates the clamping of the long material 16. The front side of the knife seat 91 is provided with a guide wheel, which facilitates the transition of the front end of the long material 16 from the roller frame 3 to the knife seat 91).

When the position detection element b11 slides to the leftmost side of the adjustment slide 12, the distance between the position detection element a7 and the position detection element b11 is also d. In actual configuration, when the position detection element a7 detects the feed slide 62, the feed push rod 65 remains flush with the tool holder 91 on the left side.

[0094] The discharge hopper 13 is arranged between the fixed length component 10 and the cutting component 9, and is provided with a movable material plate 15 driven by a hinge cylinder 14 to turn over;

[0095] The feeding slide 62 is also provided with a buffer cylinder 64, and the feeding push rod 65 is provided 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, thereby ensuring the accuracy of the length of the cut material section. The adjustment slide rail 12 is marked with a scale, and the starting reading of the scale is d.

[0096] The automatic long material cutting machine is controlled by PLC. The automatic long material cutting machine has realized full automation, which greatly improves the working efficiency.

[0097] Example 5: Figure 6 As shown, a semi-automatic long material cutting machine according to an embodiment of the present invention is provided with the cutting length adjustment device involved in the above-mentioned embodiment 2, and the feeding is semi-automatic, specifically, the feeding is performed by the feeding power wheel 17 on the rear side of the cutting component 9.

[0098] In order to facilitate understanding of the present invention, the following description will be given in conjunction with the accompanying drawings.

[0099] The complete working process of the automatic long material cutting machine involved in Example 4 is described as follows:

[0100] 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 seat 91, the straight-line distance between the fixed-length rod 104 and the knife feed groove 911 is adjusted to the set length of a single material segment. Lock the fixed-length slider 102 to limit its free sliding.

[0101] 2. Setting the tail length: Move the position detection element b11 to the right on the adjustment slide 12. After the movement, the scale reading is d1 (d1>d), which means the tail length is determined to be d1. When the remaining tail of the actual length material 16 is less than or equal to d1 after multiple cuts, it can be automatically recognized by the position detection element b11.

[0102] 3. Loading: Multiple long materials 16 roll down in a single row and are intercepted by the abutment portion 211. The loading assembly 5 moves to make the lowest long material 16 pass over the abutment portion 211 and reach the roller 4. Specifically, the loading motor 52 causes the rotating shaft 51 to rotate one circle to achieve loading.

[0103] 4. Feeding: The feeding motor 63 causes the feeding slide 62 to move leftward along the feeding guide rail 61, and the feeding push rod 65 pushes the long material 16 to the left;

[0104] 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, and 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 is actuated to retract and reset the fixed-length rod 104, and the cutting knife 92 enters the feed groove 911 to achieve cutting. After the cutting is completed, the cutting knife 92 withdraws from the feed groove 911, and the first clamping cylinder 93 and the second clamping cylinder 94 are reset to release the long material 16; the cut material segment falls due to its own weight and is collected in the collecting box through the discharge hopper 13; the fixed-length cylinder 103 is actuated to extend the fixed-length rod 104 again, and multiple identical cutting operations are performed in this way;

[0105] 6. Removal of tailings: 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, and the remaining tailings do not need to be cut. The PLC receives the signal and controls the fixed length cylinder 103 to retract to make room. At the same time, it controls the hinge cylinder 14 to make the movable plate 15 flip over (see Figure 5), the feeding slide 62 continues to move to the left, and the feeding push rod 65 pushes the tailings into the discharge hopper 13. At this time, because the movable material plate 15 is in a flipped state, the tailings cannot enter the collecting box, that is, the tailings are removed; after the tailings are removed, the hinge cylinder 14 resets and the movable material plate 15 returns to its original state;

[0106] 7. Cycle process: The position detection element a7 detects the feeding slide 62. At this time, the feeding slide 62 reaches the far left, and the feeding push rod 65 remains flush with the tool holder 91 on the left. The PLC receives the signal to control the feeding motor 63 to rotate in the opposite direction, that is, the feeding slide 62 starts to move to the right, until the position detection element c8 detects the feeding slide 62. The feeding slide 62 reaches the far right, and the PLC receives the signal to control the feeding slide 62 to move to the left, cooperating with the loading component 5 to load again, to realize the automatic cycle of the whole machine.

Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
