The guide plate 14 is downwardly inclined, and an arc-shaped guide surface is arranged at the upper end of the guide plate 14.

[0026] The working schematic diagram of the device can be referred to as shown in Figure 1 and Figure 2 By placing the workpiece on the conveying belt 3, the first motor 4 drives the belt roller 2 to rotate, and the conveying belt 3 operates and conveys the workpiece thereon. The workpiece moves horizontally on the conveying belt 3 as a first stroke path, when the workpiece moves out from one end of the conveying belt 3, the workpiece moves to the guide plate 14, and is guided to the lower end by the guide plate 14, and then falls to the next machining position from the guide plate 14, and the workpiece slides on the guide plate 14 as a second stroke path.

[0027] By arranging the two side plates 10, the path of the workpiece on the conveying belt 3 is corrected, and the workpiece is prevented from deviating from the two sides.

[0028] Since different sizes of workpieces are considered, when the size of the workpiece changes, the second rotating disc 13 is rotated to drive the bidirectional screw rod 12 to rotate, which can drive the two side plates 10 to move synchronously and in opposite directions, so as to adjust the distance between the two side plates 10, so as to adapt to workpieces of different sizes.

[0030] The speed-reducing mechanism comprises a groove 15 formed on the flow guide plate 14, a plurality of roller bodies 16 equidistantly arranged in the groove 15, anti-skid patterns provided on surfaces of the roller bodies 16, the roller bodies 16 extending out of the groove 15, connecting shafts 17 fixedly installed at ends of the roller bodies 16, the connecting shafts 17 rotatably installed on the flow guide plate 14, a through hole 18 formed on the flow guide plate 14, the connecting shafts 17 extending into the through hole 18, friction wheels 19 fixedly installed at ends of the connecting shafts 17, a support plate 20 fixedly installed in the through hole 18, two driving shafts 21 rotatably installed on the support plate 20, belt pulleys 22 fixedly installed at ends of the driving shafts 21, a belt 23 installed between the two belt pulleys 22, anti-skid patterns provided on a surface of the belt 23, the belt 23 being in contact with the plurality of friction wheels 19, and a second motor 24 fixedly installed on the support plate 20, with an output shaft of the second motor 24 being fixedly connected with one of the driving shafts 21.

[0031] When the workpiece slides downward on the flow guide plate 14, the workpiece is accelerated, and the workpiece has a high speed when it is separated from the flow guide plate 14, and thus a great impact is generated on the workpiece when it falls on the next work station, which may cause damage to the workpiece. The speed-reducing mechanism is arranged to buffer the workpiece on the flow guide plate 14. Specifically, when the workpiece is moved out from one end of the conveying belt 3 and falls on the flow guide plate 14, one end of the workpiece is first in contact with the roller body 16, and then the workpiece is completely separated from the conveying belt 3 and located on the flow guide plate 14. There is a great friction force between the roller body 16 and the workpiece, and the workpiece can be in a stationary state on the flow guide plate 14. The second motor 24 is arranged to drive the driving shaft 21 to rotate, which drives the belt 23 to rotate and drives the plurality of friction wheels 19 to synchronously rotate through the belt 23, so that the friction wheel 19, the connecting shaft 17 and the roller body 16 synchronously rotate, and thus the plurality of roller bodies 16 synchronously rotate and rotate at a reduced speed, so as to drive the workpiece on the plurality of roller bodies 16 to move downward until the workpiece is completely separated from the flow guide plate 14 and falls on the next work station. The second travel path of the workpiece on the flow guide plate 14 is corrected, the sliding speed of the workpiece is corrected, the moving speed of the workpiece is reduced, and damage to the workpiece caused by impact is avoided.
