For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-4As shown, a wire cutting machine with an automatic feeding mechanism includes a feeding box 1, a conveying slide 2, a laser cutting head 3, a feeding slide 4, and a storage box 5. The feeding box 1 is used to store a wire reel 6 to be cut. The bottom of the feeding box 1 is provided with a feeding port 7 for only one wire reel 6 to pass through at a time. The conveying slide 2 includes an inclined chute 8, the upper end of the chute 8 is located below the feeding port 7, and the lower end of the chute 8 is provided with a front support roller 9 and a rear support roller 10 arranged in parallel. The front support roller 9 is parallel to the width direction of the chute 8, and the height of the front support roller 9 is lower than the height of the feeding port 7. A space for placing a single wire reel 6 is formed between the front support roller 9 and the rear support roller 10. The cutting position 11 of the wire reel 6 is arranged, the gap width between the front support roller 9 and the rear support roller 10 is smaller than the diameter of the wire reel 6, the laser cutting head 3 is located above the cutting position 11, and the laser cutting head 3 is driven by the first driving mechanism to move back and forth in a direction parallel to the axis of the front support roller 9, the rear support roller 10 is rotatably mounted on the bracket 12, the rear support roller 12 is driven to rotate by the rotating mechanism, and the bracket 12 is driven to rise and fall by the second driving mechanism, the unloading chute 4 is inclined, the upper end height of the unloading chute 4 is lower than the height of the cutting position 11, the lower end of the unloading chute 4 is located above the material storage box 5, and a wire connection box 13 is provided below the cutting position 11. The wire reel 6 in the upper material box 1 enters the conveying chute 2 after passing through the unloading port 7 and is arranged in sequence on the conveying chute 2 to wait for wire cutting. The first wire reel 6 at the lower end of the conveying chute 2 automatically rolls down to the cutting position 11, and the lower ends of the wire reel 6 are supported by the front support roller 9 and the rear support roller 10 on both sides. The rotating mechanism drives the rear support roller 10 to rotate, driving the wire reel 6 to rotate, and the front support roller 9 rotates accordingly. The first driving mechanism drives the laser cutting head 3 to move back and forth above the wire reel 6 on the cutting position 11 along the axis parallel to the wire reel 6, and performs laser cutting on the residual wire on the wire reel 6, and the cut wire falls into the wire receiving box 13 for collection. After the wire cutting is completed, the second driving mechanism drives the bracket 12 to descend, so that the rear support roller 10 descends to a certain height, and the wire reel 6 in the cutting position 11 that has completed the wire cutting automatically rolls down along the unloading chute 4 to the storage box 5 for recovery. After the wire reel 6 leaves the cutting position 11, the bracket 12 rises rapidly so that the rear support roller 10 is slightly higher than the front support roller 9, and the rear support roller 10 blocks the next wire reel 6 of the cutting position 11 that has just rolled down, preventing the wire reel 6 from rushing out of the cutting position 11 due to inertia. Then the rear support roller 10 descends to the same height as the front support roller 9. The rear support roller 10 does not rotate during the lifting process.

[0022] Furthermore, a vibrator is installed on the feeding box 1, and the bottom surface of the feeding box 1 is funnel-shaped. A plurality of vertically arranged and mutually parallel partitions 14 can also be installed in the feeding box 1, and the partitions 14 are also parallel to the width direction of the chute 8. The spacing between adjacent partitions 14 is slightly larger than the diameter of the wire reel 6. In this way, the wire reel 6 randomly piled up in the feeding box 1 is gradually adjusted to a state in which the axis is parallel to the width direction of the chute 8 due to the action of the partitions 14 during the vibration and falling process, so that it can smoothly pass through the discharge port 7 and enter the conveying chute 2.

[0023] Furthermore, a baffle 15 is provided at the lower end of the conveying slide 2, and the baffle 15 is driven by the third driving mechanism to extend into the conveying slide 2. A clamp 16 is provided on one side of the slide 8, and the clamp 16 is driven by the fourth driving mechanism to move along the width direction of the slide 8, and there is a spacing between the clamp 16 and the baffle 15 that can only accommodate one wire reel 6. The third driving mechanism drives the baffle 15 to extend into the conveying slide 2 to block the wire reel 6 at the bottom of the conveying slide 2, so that the wire reels 6 of the conveying slide 2 can maintain a posture with the axis parallel to the width direction of the slide 8. After the baffle 15 blocks the wire reel 6 at the bottom of the conveying slide 2, the fourth driving mechanism drives the clamp 16 to support the wire reel 6 near the bottom wire reel 6, so that the wire reel 6 is clamped and fixed in the slide 8. After there is no wire reel 6 in the cutting position 11, the baffle 15 withdraws from the conveying slide 2, and the wire reel 6 at the bottom of the conveying slide 2 automatically rolls down to the cutting position 11, and then the baffle 15 extends into the conveying slide 2 again, and the clamping plate 16 releases the clamped wire reel 6, and the remaining wire reels 6 in the conveying slide 2 slide down one by one. After the wire reel 6 is stationary, the clamping plate 16 supports the next wire reel 6. Repeat the above steps to load the wire reels 6 in the conveying slide 2 into the cutting position 11 in sequence according to the set state.

[0024] Furthermore, a wire hooking device is provided on one side of the cutting position 11 near the rear support roller 10, and the wire hooking device includes a plurality of wire hooking rods 17 arranged in sequence along the axial direction of the rear support roller 10, and the upper end of the wire hooking rod 17 has a hook portion 18. The cut wire on the rotating wire reel 6 is hooked by the hook portion 18 at the upper end of the wire hooking rod 17, and the hooked wire falls into the wire receiving box 13. The opening direction of the hook portion 18 is opposite to the rotation direction of the wire reel 6 in the cutting position 11.

[0025] Further, the hooking rods 17 are divided into two groups, wherein the lower ends of one group of hooking rods 17 are bent and connected to the front lifting rod 19, and the lower ends of the other group of hooking rods 17 are bent and connected to the rear lifting rod 20. The front lifting rod 19 is driven to rise and fall by the fifth driving structure, and the rear lifting rod 20 is driven to rise and fall by the sixth driving mechanism. The hooking rods 17 on the front lifting rod 19 and the hooking rods 17 on the rear lifting rod 20 are arranged alternately. The lower ends of the hooking rods 17 are connected to the front lifting rod 19 or the rear lifting rod 20 after being bent horizontally 21 and vertically 22 in sequence. The lengths of the horizontal bends 21 in the horizontal direction of the two groups of hooking rods 17 are different, so that the front lifting rod 19 and the rear lifting rod 20 can be staggered with each other in the horizontal position. One group of hooking rods 17 hooks one end of the wire reel 6 near the cutting position 11 for a period of time and then descends, and the other group of hooking rods 17 rises and approaches the wire reel 6. This is conducive to the hooked wire in the hook part 18 falling into the wire receiving box 13, and can avoid the heavy wire in the hook part 18 that is kept hooked for a long time from being blocked from falling, resulting in too much wire remaining in the hook part 18 and affecting the hooking effect. The alternately used hooking rods effectively avoid the frequency of manual cleaning of the hooking rod 17.

[0026] Furthermore, a scraping plate 23 is provided above the wire connection box 13, and a plurality of scraping slits 24 arranged in sequence are provided on the scraping plate 23, and the scraping slits 24 correspond to the hooking rods 17 one by one, and the upper end of the hooking rods 17 can movably pass through the corresponding scraping slits 24. After the hooking rods 17 are lowered, they pass through the corresponding scraping slits 24, and part of the wire automatically falls during the falling process, and part of the wire remaining in the hook part 18 falls with the hook part 18 and passes through the scraping slits 24 after deformation, and after the hooking rods 17 are raised, the hook part 18 passes through the scraping slits 24 in the reverse direction, so that the wire remaining in the hook part 18 is separated from the hook part 18 by the action of the scraping plate 23 and falls into the wire connection box 13.

[0027] Furthermore, the scraper plate 13 is arranged at an angle to avoid too many wires being accumulated on the scraper plate 13 .

[0028] Furthermore, the upper end surface of the hook portion 18 is an arcuate surface 25, and the arcuate surface 25 matches the circumferential surface of the wire winding drum 6. This can improve the wire scraping effect.

[0029] Furthermore, the first driving mechanism includes a first motor, a slide rail and a lead screw, a slider is provided on the slide rail, the laser cutting head 3 is vertically mounted on the slider, the first motor drives the lead screw to rotate, a lead screw pair is provided on the lead screw, and the lead screw pair is fixedly connected to the slider; the second driving mechanism, the third driving structure, the fourth driving mechanism, the fifth driving mechanism, and the sixth driving mechanism respectively include a cylinder, and the rotating mechanism includes a rotating motor. The first driving mechanism, the second driving mechanism, the third driving structure, the fourth driving mechanism, the fifth driving mechanism, the sixth driving mechanism, and the rotating mechanism can all adopt the driving mechanisms commonly used in the prior art, and the installation, use, and working principles of these driving mechanisms all belong to the prior art in this field.

[0030] Furthermore, the first driving mechanism is driven to rise and fall by a lifting cylinder 26, and the two ends of the slide rail are respectively fixedly connected with vertical downward pressure rods, and pressure wheels 27 are respectively installed on the pressure rods, and the axis of the pressure wheel 27 is parallel to the axis of the front support roller 19. The pressure wheel 27 descends to press the two sides of the wire reel 6, so that the wire reel 6 can contact the front support roller 9 and the rear support roller 10, and the rotation of the rear support roller 10 can fully drive the wire reel 6 to rotate, preventing the wire reel 6 from slipping and affecting the laser cutting effect.

[0031] It is worth mentioning that the technical features of the first drive mechanism, the second drive mechanism, the third drive structure, the fourth drive mechanism, the fifth drive mechanism, the sixth drive mechanism, the rotating mechanism, the lifting cylinder 26, the laser cutting head 3 and other technical features involved in the patent application of the present invention should be regarded as the prior art, and the specific structure, working principle and possible control method and spatial arrangement method of these technical features can be selected according to the conventional selection in the field, and should not be regarded as the inventive point of the patent of the present invention, and the patent of the present invention will not be further elaborated.

[0032] The preferred specific embodiments of the present invention are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the present invention without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the existing technology should be within the scope of protection determined by the claims.
