The equipment used in this cutting is generally a robot to clamp the wire harness, and then drive the wire harness to move to the predetermined position, and then the rear gate knife is pressed down to cut the wire. After the wire cutting is completed, the robot moves and resets to continue clamping the wire harness. The second half of the cutting process needs to be moved and reset because the mechanical wall needs to be moved and reset. During this process, the machine is in an idling state. Although the robot resets quickly, there is still room for cost reduction and efficiency improvement. Utility Model Content

[0029] Reference Figures 1 to 6 As shown, a wire winding and cutting machine for metal wires of a ceiling chandelier comprises a placing table 1 and a wire management component 2 fixed on the left side of the placing table 1. The wire management component 2 cleans and straightens the surface of the wire 4 to be cut by friction through the mutual extrusion of the extrusion cylinder 25 inside the wire management component 2. The straightened wire 4 rotates with the transmission belt composed of the sprocket 33 and the chain 34 in the transmission component 3, and drives the concave block 55 in the cutting component 5 to contact and extrude the first extrusion block 72 in the pushing component 7, so that the pushing bar 76 is pushed out and inserted between the lower extrusion sheet 51 and the upper extrusion sheet 52, thereby allowing the wire 4 to completely enter between the lower extrusion sheet 51 and the upper extrusion sheet 52. In this process, the blade 53 extrude and cut the wire 4.

[0030] In this embodiment, if Figure 4The wire management assembly 2 shown includes a short strip board 21 and a long strip board 22 fixed on the upper end surface of the placement table 1. There is a gap between the long strip board 22 and the short strip board 21 for the wire 4 to pass through, and the transmission assembly 3 is arranged in the gap space between the short strip board 21 and the long strip board 22, that is, one of the positioning rods 31 in the transmission assembly 3 is fixed next to the short strip board 21, and the sprocket 33 sleeved on the positioning rod 31 and the chain 34 meshing with the support plate 32 and the sprocket 33 will not contact the short strip board 21, but are close enough to allow the recessed block 55 in the cutting assembly 5 fixed on the chain 34 to conflict with the pushing assembly 7 on the long strip board 22.

[0031] It should be noted that a placement opening 23 is opened on the opposite surfaces of the short strip 21 and the long strip 22. The upper and lower end walls of the inner cavity of the placement opening 23 are connected to the rotating rod 24 through bearings. The extrusion cylinder 25 is sleeved on the rotating rod 24. The extrusion cylinder 25 can be a soft cylinder or a hard cylinder but the surface is wrapped with a soft cover. After the silk thread 4 is inserted into the gap between the short strip 21 and the long strip 22, the two extrusion cylinders 25 will squeeze the silk thread 4 between them, and then straighten or clean the silk thread 4.

[0032] In this embodiment, if Figure 2 The cutting assembly 5 shown includes a recessed block 55, and the recessed block 55 is fixed on a single chain plate of the chain 34, so that the recessed block 55 can match the plane change caused by the chain 34 moving to the arc bend of the sprocket 33. The recessed block 55 is outside, and the upper and lower end walls of the recess are respectively fixed with an upper extrusion sheet 52 and a lower extrusion sheet 51. Only one side of the upper extrusion sheet 52 and the lower extrusion sheet 51 is fixed, and the other side is inclined to move toward the middle of the recess, so that the upper extrusion sheet 52 and the lower extrusion sheet 51 become elastic sheets, which can move downward by squeezing the raised part, and naturally return to the original position after the lack of squeezing. At this time, the upper extrusion sheet 52 and the lower extrusion sheet 51 are fixed at the side edges closest to the upper extrusion sheet 52 and the lower extrusion sheet 51. The blade 53 cuts the wire 4 in a cross-cutting manner. To facilitate the wire 4 to enter between the two blades 53 under extrusion, the side edges of the two blades 53 are arc-shaped and have blades thereon, so that when the wire 4 moves between the two blades 53 due to extrusion, the blades on the blades 53 will cut the wire 4 in advance, and then as the wire enters between the two blades 53, the caliber gradually expands. To ensure that the blade 53 can smoothly cut the wire, compression springs 54 are fixed on the opposite sides of the upper extrusion sheet 52 and the lower extrusion sheet 51, and the other ends of the compression springs 54 are respectively fixed to the notches, so that the wire 4 is gradually deepened as the blade 53 cuts the wire 4 until the wire 4 is cut.

[0033] In this embodiment, if Figure 3The lower extrusion sheet 51 and the upper extrusion sheet 52 in the cutting assembly 5 are relatively inclined. After the wire harness 4 is cut, the lower extrusion sheet 51 and the upper extrusion sheet 52 can still be squeezed by the compression spring 54, so that the wire harness 4 can be clamped and pulled to move to a predetermined position along with the transmission assembly 3. Then, the second extrusion block 61 is fixed to the upper end surface of the placement table 1 through the positioning column 62 and the upper side wall of the positioning column 62 through the connecting strip. Because one side of the second extrusion block 61 is inclined, and the wire harness 4 is pulled to the predetermined position along with the transmission assembly 3, the wire harness 4 can be clamped and pulled to move to a predetermined position along with the transmission assembly 3. In the gap between the lower extrusion sheet 51 and the upper extrusion sheet 52, when the concave block 55 moves with the transmission assembly 3, the inclined surface of the second extrusion block 61 can be inserted between the two blades 53, thereby increasing the width of the gap between the lower extrusion sheet 51 and the upper extrusion sheet 52, so that the wire 4 clamped between the lower extrusion sheet 51 and the upper extrusion sheet 52 falls to the upper end surface of the placement table 1 due to lack of extrusion. Of course, in this process, the other end of the wire 4 has been cut and cut off, thereby obtaining a metal wire of a certain length.

[0034] In this embodiment, if Figure 5 The pushing assembly 7 shown includes two first slots 71 opened at the upper and lower parts of the inner surface of the long plate 22, and the inner cavity between the two first slots 71 is penetrated by a moving slot 73, the moving slot 73 is a convex slot, and the convex part is connected to the outside, corresponding to the middle part of the two first slots 71 where the two first slots 71 are opposite to each other, the first extrusion block 72 is inserted in the first slot 71, and the convex part of the moving slot 73 is inserted into the pushing strip 76, and the upper and lower end walls of the moving slot 73 are fixed with a plug rod 75, and the plug rod 75 is sleeved with a torsion spring 78 and a pushing piece 74, and the two ends of the torsion spring 78 are respectively fixed to the inner wall of the plug-in connection between the plug rod 75 and the pushing piece 74, and at this time, when the torsion spring 78 is not twisted, the pushing piece 74 is in an inclined state. The first and second squeeze bars 74 are in contact with each other, and the first and second squeeze bars 74 are in contact with each other, so that the first and second squeeze bars 74 are in contact with each other, and the ... and the squeeze bars 76 are in contact with each other, so that the first and second squeeze bars 74 are in contact with each other, and the squeeze bars 74 are in contact with each other, and the squeeze bars 76 are in contact with each other, so that the first and second squeeze bars 74 are in contact with each other, and the squeeze bars 76 are in contact with each other,

[0035] It should be noted that a positioning tube 77 is fixed to the inner surface of the long plate 22 , and the wire 4 is inserted into the positioning tube 77 , so that the cutting component 5 and the pushing component 7 have enough spare space to cut and pull the wire 4 .

[0036] It should be noted that a pull rope 79 is fixed between the push bar 76 and the push sheet 74. When the push sheet 74 lacks squeezing, it can be reset by the torsion spring 78, and the pull rope 79 can drive the push bar 76 to reset as the push sheet 74 is pulled and reset.

[0037] At this point, with the rotation of the sprocket 33 and the chain 34, the concave block 55 fixed on a single chain plate in the chain 34 will move to the inner surface of the long plate 22 where the pushing component 7 is installed. At this time, the concave block 55 can first contact the front end of the silk thread 4 inserted in the positioning tube 77, and through the outer arc surface of the blade 53 fixed on the lower extrusion plate 51 and the upper extrusion plate 52, the silk thread 4 is gradually moved between the two blades 53. However, the silk thread 4 is relatively soft when it is not pulled into a taut state, and it is easy to bend under the extrusion of the side edge of the blade 53 and cannot enter between the two blades 53, so that the silk thread 4 cannot be cut.

[0038] To this end, the upper and lower parts of the long strip 22 next to the positioning cylinder 77 are provided with a first slot 71, and the first extrusion block 72 is inserted into the first slot 71. The two first extrusion blocks 72 are also provided with a push bar 76 extending into the long strip 22. The first extrusion block 72 and the push bar 76 are connected by a push sheet 74 that can rotate around the insertion rod 75, so that the upper and lower ends of the concave block 55 move with the conveyor belt to squeeze the first extrusion block 72, so that the first extrusion block 72 moves into the first slot 71 and squeezes one side of the push sheet 74, so that the other side of the push sheet 74 pushes the push bar 76 Move outward, at this time, the pushing bar 76 corresponds to between the lower extrusion sheet 51 and the upper extrusion sheet 52, and the pushing bar 76 pushes the silk thread 4 to enter between the lower extrusion sheet 51 and the upper extrusion sheet 52 and gives the extrusion force to the lower extrusion sheet 51 and the upper extrusion sheet 52 through the compression spring 54, so that the blade 53 has a blocking force to cut off the silk thread 4 entering between the lower extrusion sheet 51 and the upper extrusion sheet 52. After the silk thread 4 is cut off, the extrusion force of the compression spring 54 causes the lower extrusion sheet 51 and the upper extrusion sheet 52 to clamp the uncut part of the silk thread 4 and pull the silk thread 4 to move with the conveyor belt.

[0039] It should be noted that when the wire 4 is cut off, the concave block 55 in the previous cutting component 5 is moved to the extrusion member 6, and the inclined surface of the second extrusion block 61 in the extrusion member 6 is inserted into the gap between the lower extrusion sheet 51 and the upper extrusion sheet 52 to expand the gap, so that the wire 4 can be separated from the lower extrusion sheet 51 and the upper extrusion sheet 52, thereby completing the pulling and cutting of the wire 4 in a cyclic manner.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
