DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0051] When it is necessary to thread the silk thread, the second driving mechanism 400a drives the two transmission wheels 200a to press against each other, and the first driving mechanism 300a drives the two transmission wheels 200a to rotate. The silk thread is threaded into the first threading channel 110a, and the free end extends between the two transmission wheels 200a. In this way, the two rotating transmission wheels 200a will downwardly pass the free end of the silk thread into the second threading channel in a downward conveying manner, and continue to convey the silk thread downward along the second threading channel. This solution takes a short time to thread the silk thread and has high efficiency. After the threading of the silk thread is completed, the first driving mechanism 300a drives the two transmission wheels 200a to stop rotating, and the second driving mechanism 400a drives the two transmission wheels 200a to separate, so that the silk thread is no longer pressed by the two transmission wheels 200a, and subsequent actions can be performed normally.

[0052] In some examples, such as Figures 1 to 9 As shown, the second driving mechanism 400a includes: a second transmission structure 410a, which is arranged on the base 100a and is transmission-connected to the two transmission wheels 200a; and a second driving structure 420a, which is transmission-connected to the second transmission structure 410a, and the second driving structure 420a is configured to drive the second transmission structure 410a to move the two transmission wheels 200a toward each other to press against each other and move away from each other to separate.

When the piston rod of the telescopic cylinder 421a is contracted, the telescopic cylinder 421a and the connecting member 423a will pull the second ends of the two first swing arms 412a to swing synchronously toward each other, so that the two transmission wheels 200a move toward each other and press against each other; when the piston rod of the telescopic cylinder 421a is extended, the telescopic cylinder 421a and the connecting member 423a will push the second ends of the two first swing arms 412a to swing synchronously in opposite directions, so that the two transmission wheels 200a move in opposite directions and separate from each other.

[0058] That is, the output shaft of the first driving motor 310a is located at the second end of one of the two first swing arms 412a, a transmission gear 320a and a transmission wheel 200a are both fixedly mounted on the output shaft of the first driving motor 310a, the other transmission gear 320a and the other transmission wheel 200a are both fixedly mounted on the first rotating shaft 330a, and the two ends of the first rotating shaft 330a are rotatably mounted on the second end of the other of the two first swing arms 412a and the connecting member 423a. When the two transmission gears 320a are meshed and transmitted, the two transmission wheels 200a rotate synchronously, which can ensure that the silk thread can smoothly pass into the second threading channel.

[0059] In some examples, such as Figures 3 to 9 , Fig.11 As shown, the base body 100a is provided with two functional holes 140a whose side walls intersect, and the two functional holes 140a (which can be set as two arc holes) are arranged in sequence in the horizontal direction, the first wire threading channel 110a is located above the two functional holes 140a, and the lower end of the first wire threading channel 110a is connected to the upper part of the intersection of the two functional holes 140a, the second wire threading channel is located below the two functional holes 140a, and the upper end of the second wire threading channel is connected to the lower part of the intersection of the two functional holes 140a, the lower end of the first wire threading channel 110a is directly opposite to the upper end of the second wire threading channel in the up and down direction, and the two transmission wheels 200a are respectively arranged in the two functional holes 140a, and can move toward each other to press and move away from each other to separate in the two functional holes 140a.

[0060] In some examples, such as Figure 2 , Figure 3 , Figure 7 , Fig. 9 and Fig.11As shown, at least one of the upper end of the first wire threading channel 110a and the lower end of the second wire threading channel is provided with a wire guide nozzle. Preferably, the first wire threading channel 110a is arranged in the up-down direction, and the upper end of the first wire threading channel 110a is provided with an upper wire guide nozzle 150a, and the second wire threading channel is arranged in the up-down direction, and the lower end of the second wire threading channel is provided with a lower wire guide nozzle 160a, and the wire guide nozzle includes an upper wire guide nozzle 150a and a lower wire guide nozzle 160a.

[0061] The base 100a is arranged as a vertical base plate, the first driving motor 310a, two first swing arms 412a, two semicircular gears 413a and two transmission gears 320a are located on the first side of the base plate, and the telescopic cylinder 421a and the connecting member 423a are located on the second side of the base plate.

[0062] In some exemplary embodiments, Figures 1 to 3 , Fig.10 As shown, the upper automatic wire threading device also includes: a second swing arm mechanism 500a, which is arranged on the base 100a; and two guide members 600a, which are arranged on the second swing arm mechanism 500a, and the second swing arm mechanism 500a is configured to drive the two guide members 600a to swing and drive the two guide members 600a to relative close and separate, and the two guide members 600a construct a first wire guide channel based on the relative closeness.

[0063] When the two guide members 600a are aligned and swing to a stop at the working position, the second threading channel corresponds to the first wire guiding channel, and the wire delivered from the second threading channel passes into the first wire guiding channel and continues to be delivered along the first wire guiding channel. After the threading of the wire is completed, the two guide members 600a are separated first, and then the two guide members 600a are swing to a set non-working position (such as the initial position).

[0066] The process of threading the silk thread on the automatic threading device is as follows:

[0068] The finger cylinder 530a drives the two guide members 600a to move toward each other to align, and the second drive motor 510a drives the second swing arm 520a to swing forward, so that the two guide members 600a swing to the working position. At this time, the first wire guide channel is arranged in the up-down direction, and the upper end of the first wire guide channel is located directly below the outlet of the lower wire guide nozzle 160a;

[0069] The wire is passed through the first wire threading channel 110a from the upper wire guide nozzle 150a, and the free end extends between the two transmission wheels 200a. The two rotating transmission wheels 200a will convey the free end of the wire downward into the second wire threading channel, and continue to convey the wire downward along the second wire threading channel. Then the free end of the wire is passed through the first wire guide channel from the lower wire guide nozzle 160a, and passes through the first wire guide channel and out from the lower end of the first wire guide channel.

[0070] After the threading action is completed: the piston rod of the telescopic cylinder 421a extends, driving the second ends of the two first swing arms 412a to swing synchronously in opposite directions around the axes of the two second rotating shafts 411a, and the two first swing arms 412a drive the two transmission wheels 200a to move synchronously in opposite directions and separate from each other, and the two first swing arms 412a also drive the two transmission gears 320a to separate, and control the first drive motor 310a to stop; the finger cylinder 530a drives the two guide members 600a to move in opposite directions to separate, and then the second drive motor 510a drives the second swing arm 520a to swing in the opposite direction, so that the two guide members 600a swing from the working position to the set non-working position (such as the initial position). In this way, the thread can perform subsequent actions normally.

When the free end of the silk thread extends into the mounting hole 160b and is threaded to the guide wheel 510b, the rotating guide wheel 510b and the inner circumferential surface of the mounting hole 160b jointly guide the free end of the silk thread to penetrate into the third threading channel 170b, and the silk thread will continue to be conveyed along the third threading channel 170b.

The wire guide tube 620b is communicated with the third threading passage 170b through a docking channel member 700b.

[0085] The process of threading the silk thread by the automatic threading device is as follows:

The wire drum 300d stops at a set position, at which time the trigger surface 411d corresponds to the mating surface 211d, so that the trigger surface 211d moves toward the mating surface 411d along the axial direction of the wire drum 300d, and pushes the mating surface 411d to move toward the outside of the wire drum 300d along the axial direction of the through hole, so that the wire pressing piece 500d is spaced from the outer peripheral surface of the wire drum 300d.

At this time, since the trigger surface 211d is separated from the matching surface 411d, the trigger mechanism 200d will not interfere with the rotation of the wire drum 300d and the telescopic mechanism 400d around the axis of the wire drum 300d. The telescopic mechanism 400d has a simple structure and mature technology.

During this process, the guide rod 410d moves axially toward the wire reel 300d along the axial direction of the through hole, and finally the trigger surface 211d is separated from the matching surface 411d. At this time, the wire pressing piece 500d is pressed against the outer circumferential surface of the wire reel 300d, and the trigger mechanism 200d will not interfere with the rotation of the wire reel 300d and the telescopic mechanism 400d around the axis of the wire reel 300d.

The second guide member 230d is configured to guide the trigger rod 210d to move axially along the wire reel 300d to prevent the trigger rod 210d from tilting during the axial movement along the wire reel 300d, thereby causing the trigger surface 211d and the mating surface 411d to be misaligned.

[0105] In some embodiments, Fig. 20 , Fig.21 and Fig.23 As shown, the fifth drive mechanism 220d is a cylinder (or oil cylinder, etc.), the trigger rod 210d is fixedly connected to the piston rod of the cylinder, and the second guide member 230d is a guide cylinder, which is sleeved outside the trigger rod 210d and fixedly connected to the cylinder barrel of the cylinder.

In this scheme, the first wire reel seat 600d and the second wire reel seat 700d limit the two ends of the wire reel 300d respectively, so that the rotation process of the wire reel 300d is more stable. Among them, the fourth drive mechanism 100d is set to a drive motor.

[0107] Medium wire cutting machine: Fig.24 As shown, it includes an automatic wire clamping device for a wire drum, a tension adjusting device, an upper automatic wire threading device and a lower automatic wire threading device which are arranged in sequence, the outlet of the wire threading tube 620 corresponds to the wire pressing piece 500d, and the first wire guiding channel of the upper automatic wire threading device (when in the working position) corresponds to the lower wire guiding nozzle 150b of the lower automatic wire threading device.

[0108] exist Fig.24 In the figure, reference numeral 10 is a transmission wheel, reference numeral 20 is a wire, reference numeral 30 is a lower conductive block, and reference numeral 40 is an upper conductive block.

[0109] The automatic wire threading process of the medium wire 20 cutting machine is as follows:

[0110] The piston rod of the telescopic cylinder 421a contracts, so that the second ends of the two first swing arms 412a swing synchronously toward each other around the axes of the two second rotating shafts 411a, and the two first swing arms 412a drive the two transmission wheels 200a to move synchronously toward each other and press against each other, and the two first swing arms 412a also drive the two transmission gears 320a to mesh, and the first drive motor 310a drives the two transmission gears 320a to rotate synchronously, thereby ensuring that the two transmission wheels 200a rotate synchronously;

[0111] The finger cylinder 530a drives the two guide members 600a to move toward each other to align, and the second drive motor 510a drives the second swing arm 520a to swing forward, so that the two guide members 600a swing to the working position. At this time, the first wire guide channel is arranged in the up-down direction, and the upper end of the first wire guide channel is located directly below the outlet of the lower wire guide nozzle 160a;

[0112] The piston rod of the telescopic cylinder 421b contracts, so that the second ends of the two first swing arms 412b swing synchronously toward each other around the axes of the two second rotating shafts 411b, and the two first swing arms 412b drive the two transmission wheels 200b to move synchronously toward each other and press against each other, and the two first swing arms 412b also drive the two transmission gears 320b to mesh, and the first drive motor 310b drives the two transmission gears 320b to rotate synchronously, thereby ensuring that the two transmission wheels 200b rotate synchronously, and the third drive motor drives the guide wheel 510b to rotate;

[0113] After the wire 20 wound on the wire drum passes through the tensioning wheel 200c, it passes through the first wire threading channel 110a from the upper wire guide nozzle 150a, and the free end extends between the two transmission wheels 200a. The two rotating transmission wheels 200a will convey the free end of the wire 20 downward into the second wire threading channel, and continue to convey the wire 20 downward along the second wire threading channel. Then, the free end of the wire 20 passes through the first wire guide channel from the lower wire guide nozzle 160a, and passes through the first wire guide channel. The channel passes through the lower end of the first wire guide channel, and then passes through the lower wire guide nozzle 150b and the first wire threading channel 110b in sequence. When the free end of the wire 20 extends between the two transmission wheels 200b, the two rotating transmission wheels 200b will convey the free end of the wire 20 downward into the second wire threading channel 120b, and continue to convey the wire 20 downward along the second wire threading channel 120b. When the free end of the wire 20 extends into the mounting hole 160b and passes to the guide hole 160b, the wire 20 passes through the lower wire guide nozzle 150b and the first wire threading channel 110b. When the wire 20 is at the wheel 510b, the rotating guide wheel and the inner circumference of the mounting hole 160b jointly guide the free end of the wire 20 to pass into the third wire threading channel 170b, and the free end of the wire 20 continues to be transported along the third wire threading channel 170b, and then the free end of the wire 20 passes into the wire guide tube 620b. During the process of the wire 20 being transported along the wire guide tube 620b, the wire drum 300d stops at the set position, and the trigger mechanism 200d drives the telescopic mechanism 400d to move, so that the guide rod 41 0d is extended (making the wire pressing piece 500d in the open position), controlling the tensioning wheel 200c to move to the right to release the wire 20, ensuring that the wire 20 passes through the outlet of the wire guide tube 620b and extends between the wire pressing piece 500d and the wire reel 300d, controlling the trigger mechanism 200d to reset, and then the telescopic mechanism 400d is reset (making the wire pressing piece 500d in the wire clamping position), and the wire pressing piece 500d presses the free end of the wire 20 between the wire pressing piece 500d and the wire reel 300d.

[0114] Then, the piston rod of the telescopic cylinder 421a extends, driving the second ends of the two first swing arms 412a to swing synchronously in opposite directions around the axes of the two second rotating shafts 411a, and the two first swing arms 412a drive the two transmission wheels 200a to move synchronously in opposite directions and separate from each other. The two first swing arms 412a also drive the two transmission gears 320a to separate, and control the first drive motor 310a to stop; the finger cylinder 530a drives the two guide members 600a to move in opposite directions to separate, and then the second drive motor 510a drives the second swing arms 520a swings in the opposite direction, causing the two guide members 600a to swing from the working position to the set non-working position (such as the initial position); the piston rod of the telescopic cylinder 421b extends, driving the second ends of the two first swing arms 412b to swing synchronously in opposite directions around the axes of the two second rotating shafts 411b, and the two first swing arms 412b drive the two transmission wheels 200b to move synchronously in opposite directions and separate from each other. The two first swing arms 412b also drive the two transmission gears 320b to separate from each other, controlling the first drive motor 310b and the third drive motor to stop.

[0115] The automatic wire drawing process of the medium wire 20 cutting machine is as follows:

[0116] The wire reel 300d is controlled to stop at the set position, and the trigger mechanism 200d drives the telescopic mechanism 400d to operate, so that the guide rod 410d extends (so that the wire pressing piece 500d is located in the open position), and the tensioning wheel 200c is controlled to move to the left, and the free end of the wire 20 is pulled out from between the wire pressing piece 500d and the wire reel 300d. The trigger mechanism 200d is controlled to reset, and the telescopic mechanism 400d is reset (so that the wire pressing piece 500d is located in the wire clamping position), and the wire pressing piece 500d is pressed on the outer peripheral surface of the wire reel 300d again, and then the wire reel 300d is controlled to rotate, so that the free end of the wire 20 is retracted to the lower wire guide nozzle 160a.

[0117] In summary, the technical solution provided by the embodiment of the present invention is that when it is necessary to thread the silk thread, the second drive mechanism drives the two transmission wheels to press against each other, and the first drive mechanism drives the two transmission wheels to rotate. The silk thread is threaded in the first threading channel, and the free end extends between the two transmission wheels. In this way, the two rotating transmission wheels will downwardly convey the free end of the silk thread into the second threading channel, and continue to convey the silk thread downward along the second threading channel. This solution takes a short time to thread the silk thread and has high efficiency. After the threading of the silk thread is completed, the first drive mechanism drives the two transmission wheels to stop rotating, and the second drive mechanism drives the two transmission wheels to separate. In this way, the silk thread is no longer pressed by the two transmission wheels, and subsequent actions can be performed normally.
