[0026] In one or more embodiments, the first position - adjusting plate 1 and the second position - adjusting plate 2 are slidably arranged on the base 7 through guide rails 6. See Figure 3 , the base 7 is provided with guide rails 6, and both the first position - adjusting plate 1 and the second position - adjusting plate 2 are slidably installed on the guide rails 6 through sliders. Through this setting, the resistance when the first position - adjusting plate 1 and the second position - adjusting plate 2 move towards or away from each other can be reduced, improving the use effect of the present application.
[0027] In one or more embodiments, a driving structure for driving the double - lead screw 5 to rotate is provided at the end of the double - lead screw 5. By controlling the double - lead screw 5 to rotate through the driving structure, the distance between the first position - adjusting plate 1 and the second position - adjusting plate 2 can be adjusted, and then the distance between the first conveyor line 3 and the second conveyor line 4 can be adjusted.
[0028] In the first embodiment of the driving structure, the driving structure is a servo motor. The rotating shaft end of the servo motor is connected to the end of the double - lead screw 5. Through this setting, the distance between the first position - adjusting plate 1 and the second position - adjusting plate 2 can be adjusted automatically, and then the distance between the first conveyor line 3 and the second conveyor line 4 can be adjusted, reducing the manual operation process and improving the adjustment accuracy of the distance between the first conveyor line 3 and the second conveyor line 4.
[0029] In the second embodiment of the driving structure, the driving structure is a crank 8.
[0030] See Figure 1, the crank handle 8 includes a turntable and a crank, the crank is eccentrically arranged on the turntable, and the end of the bidirectional lead screw 5 is installed at the middle position of the turntable; by rotating the crank, the first adjustment plate 1 and the second adjustment plate 2 can move towards or away from each other, and then the distance between the first conveyor line 3 and the second conveyor line 4 can be adjusted, which has the advantages of simple structure and low production cost. In other possible embodiments, a scale plate is installed on the base 7 at the turntable of the crank handle 8. When the turntable is rotated, by comparing the scales on the scale plate, the accuracy of the distance adjustment between the first conveyor line 3 and the second conveyor line 4 can be improved.
[0031] In one or more embodiments, a clamping structure 9 for fixing the position of the bidirectional lead screw 5 is configured on the base 7, and the clamping structure 9 is a hoop. See Figure 1 , Figure 3 , the hoop is applicable to the case where the driving structure is the crank handle 8; when the distance between the first conveyor line 3 and the second conveyor line 4 is adjusted, the hoop can be controlled to clamp the bidirectional lead screw 5, reducing the possibility of the bidirectional lead screw 5 rotating again, and then ensuring the stability of the first conveyor line 3 and the second conveyor line 4 during operation.
[0032] In one or more embodiments, the first conveyor line 3 and the second conveyor line 4 have the same structure.

The driving motor 351 controls the rotation of the spline shaft 352, so that the driving pulleys 33 on the first positioning plate 1 and the second positioning plate 2 rotate, and then realizes the synchronous rotation of the conveyor belts 32 installed on the first positioning plate 1 and the second positioning plate 2, realizing the transportation of materials; when it is necessary to adjust the distance between the first conveying line 3 and the second conveying line 4, control the driving structure to adjust the distance between the first positioning plate 1 and the second positioning plate 2. At this time, since the two driving pulleys 33 are respectively rotatably installed on the first positioning plate 1 and the second positioning plate 2, so that the two driving pulleys 33 can move respectively with the first positioning plate 1 and the second positioning plate 2, and the connection between the two driving pulleys 33 and the spline shaft 352 is a special-shaped connection, the driving motor 351 can still drive the spline shaft 352 to rotate, and then realize the rotation of the driving pulley 33 and the driven pulley 31, realizing the adjustment of the distance between the first conveying line 3 and the second conveying line 4 without stopping the machine, meeting the use requirements in different situations, and having practicality.

Among them, the second synchronous motor can drive the driving pulley 33 installed on the second positioning plate 2 to rotate, and the second synchronous motor can move horizontally synchronously with the second positioning plate 2.
[0038] See Figure 1 , Figure 4, the driving device includes a first synchronous motor and a second synchronous motor. Among them, the first conveyor line 3 is driven by the first synchronous motor, and the second conveyor line 4 is driven by the second synchronous motor. That is to say, the first synchronous motor and the second synchronous motor are respectively fixedly installed on the side surface of the first position adjustment plate 1 and the side surface of the second position adjustment plate 2; when adjusting the distance between the first conveyor line 3 and the second conveyor line 4, the first synchronous motor can move synchronously with the first position adjustment plate 1, and the second synchronous motor can move synchronously with the second position adjustment plate 2. Through this setting, it is also possible to adjust the distance between the first conveyor line 3 and the second conveyor line 4 without stopping the machine.
