[0039] In the present invention, the main drive roller 314, the first auxiliary pinch roller 301, and the second auxiliary pinch roller 302 are all rubber-coated rollers, which increase the frictional force exerted on the lead wire a. The main drive roller 314 is driven by a motor power unit (not shown), while the first and second auxiliary pinch rollers 301, 302 are unpowered.

Under the action of the first cutting cylinder 1001, the first wire cutting blade 1004 is inserted into the first feed gap d between the upper guide block 1008 and the lower guide block 1009 to cut off the lead wire a.

[0043] See Figure 2 、 Figure 3 、 Figure 5 The Z-axis drive device 16 and the Y-axis drive device 17 constitute a two-dimensional motion device in the vertical and horizontal directions, wherein the Z-axis drive device 16 includes a Z-axis motor 1604 fixed on the chassis 2 through a mounting plate 1601, and a Z-axis slide 1603 driven by the Z-axis motor 1604 to move up and down along the vertical track 1602 on the mounting plate 1601; the Y-axis drive device 17 includes a Y-axis motor 1701 fixed on the Y-axis slide 1603, and a Y-axis slide 1702 driven by the Y-axis motor 1701 to move back and forth along the horizontal track 1605 on the Z-axis slide 1603, and the Y-axis slide 1702 is fixedly connected to the bracket 7 in the lead drive device 3. The lead wire driving device 3 cooperates with the paper tube bundle fixed rotating device 6 through a two-dimensional motion device to meet the lead wire insertion action of the paper tube bundle b, among which the Z-axis driving device 16 is responsible for driving the lead wire driving device 3 to move vertically in the Z direction, the Y-axis driving device 17 is responsible for the horizontal movement of the lead wire driving device 3 in the Y direction, and the paper tube bundle fixed rotating device 6 is responsible for the rotation of the paper tube bundle b.

[0044] When the equipment is working, the operator puts 9 lead reels 102 on the hanging shaft 101 of the lead reel rack 1. The equipment can use 9 lead wires a at a time. Each lead wire a is led out from the lead reel 102, passes through the guide roller 103 and the workshop partition wall and is introduced into the equipment, and passes through the lead abnormality cutting device 13, the lead guide wheel mechanism 9, the lead clamping mechanism 8, and the lead driving device 3 in sequence.

[0045] The paper tube bundle b is loaded manually. Figure 11 As shown, the operator places a paper tube bundle b, which is made by bundling several paper tubes b1 in a regular hexagon, on the positioning fixture 611 of the paper tube bundle fixing and rotating device 6, and positions it by the open positioning plate 608, and then covers the threading positioning fixture 610 on the top of the paper tube bundle b. In order to adapt to paper tube bundles b with different paper tube heights, the height of the threading positioning fixture 610 can be adjusted by rotating the guide column 609 to extend the height of the support seat 612.

[0046] Lead insertion principle: This equipment divides the paper tube b1 in the paper tube bundle b into three areas A, B, and C according to 120 degrees and inserts the lead wires in sequence. Figure 11 As shown, except for the central paper tube b1 (referred to as the central paper tube b0), the paper tubes b1 in each area of the paper tube bundle b are arranged in a rhombus shape with 9 rows and 8 columns. The lead wire insertion operation of the paper tubes b1 in each area is performed row by row. After each area is inserted, the paper tube fixing and rotating device 6 drives the paper tube bundle b to rotate 120 degrees clockwise. The entire lead wire insertion operation is completed in two steps. Step 1: First, one of the 9 lead wires a is pressed by the first pressing plate 803 of the lead pressing mechanism 8 and the second auxiliary pressing roller 302 of the lead driving device 3 is opened, and the 8 lead wires a are used to simultaneously insert the paper tube b1 in one area of the paper tube bundle b. The length of the lead wire a is set as needed; under the drive of the main driving roller 314 and the first auxiliary pressing roller 301, the 8 lead wires a are inserted into the paper tube b1 of the paper tube bundle b through the first wire hole e of the upper guide block 1008 and the lower guide block 1009 in the lead cutting device 10 and the lead guide port c on the threading and positioning fixture 610 in the paper tube bundle fixing and rotating device 6. When the lead driving device 3 has inserted the lead wires a of one row of paper tubes b1 and needs to insert the next row, the first wire cutting blade 1004 in the lead cutting device 10 cuts the lead wires in the first feed gap d between the upper guide block 1008 and the lower guide block 1009. a, the Z-axis drive device 16 drives the lead drive device 3 to lift and separate the lead a from the lead guide port c on the threading positioning fixture 610 at the top of the paper tube bundle b, and then the Y-axis drive device 17 drives the lead drive device 3 to move a set position, so that the 8 lead wires a are moved to the next row of ordinary paper tubes b13, until they are all inserted, and the insertion of the paper tubes b1 in the A, B, and C areas is completed in the above manner; Step 2: Insert the lead of the central paper tube b0, the first pressing plate 803 of the lead clamping mechanism 8 opens and closes the second auxiliary pressing roller 302 of the lead drive device 3, and at the same time the second pressing plate 804 of the lead clamping mechanism 8 presses the above 8 leads and opens the first auxiliary pressing roller 301 of the lead drive device 3. At this time, the 9th lead is inserted into the central paper tube b0 alone under the action of the main driving roller 314 and the second auxiliary pressing roller 302 of the lead drive device 3.

[0047] like Figure 1 As shown, in terms of personnel operation safety, a grating detection device 18 is provided at the entrance A of the chassis 2 to protect the operators who enter the chassis 2 to put the paper tube bundles b in and out. After the operator puts the paper tube bundles b in, if the operator does not evacuate to a safe area, the operation panel 31 will not start the operation of the equipment. Only when the operator evacuates to a safe area can the equipment be started.

[0048] like Figure 1 、 Figure 5 、 Figure 9 As shown, in terms of material protection, a lead break detection device 4 is installed on the bracket 7 of the equipment, including photoelectric detection sensors 401 and 402. When a lead a breaks abnormally, the lead break detection device 4 immediately alarms and shuts down.

[0049] Since the lead is a flammable and explosive product, high fire safety requirements are required. When the equipment emits abnormal smoke, the smoke detection device 5 in the chassis 2 senses the smoke signal, and the lead abnormal cutting device 13 is immediately started. Under the action of the second cutting cylinder 1309, the second wire cutting blade 1303 is inserted into the second cutting gap d′ between the front guide block 1305 and the rear guide block 1306, cutting the lead a, so that the lead a on the lead reel 102 is disconnected from the equipment. At the same time, after the lead a is cut, the cut lead will automatically fall into the water tank 14 prepared in advance, and the equipment will immediately be powered off and shut down and the sprinkler system 15 will be turned on. Even if an open fire occurs, the lead reel 102 and the equipment can be spatially isolated by an isolation wall to ensure the safety of the equipment and personnel.
