[0007] Further, the chain transmission assembly includes four gears arranged in four-corner symmetry and a tensioning wheel, the four gears and the tensioning wheel are rotatably installed on the inner wall of the machine case, the chain is wound between the four gears and the tensioning wheel, a driving motor is further arranged on the outer wall of the machine case and is in transmission connection with one of the gears, and the adapter rod is arranged outside the chain between the lower two gears. In this way, the periodic reciprocating motion of the chain is realized by the action of the driving motor, so as to control the back-and-forth reciprocating motion of the adapter rod.

[0008] Further, a sensor is arranged below the inner side wall of the cabinet for detecting the moving position of the adapter rod. When the sensor detects that the adapter rod moves to the position, the electromagnet is powered off, the magnetic force between the electromagnet and the iron slider disappears, so that the push rod and the moving carrier can be separated from each other. During the rising of the moving carrier, the push rod does not rise synchronously with the moving carrier, but stays below the cabinet.

[0009] Further, the driving motor is provided with a protective shell. The protective shell protects the internal driving motor, which can prevent the driving motor from being damaged by external collision, impact, dust, moisture and other environmental factors.

Through the design of the anti-skid protrusions, the carrier can be stably placed on the moving carrier, and the carrier can be smoothly and stably sent into the moving carrier without shaking during the automatic sending process of the double-layer conveying line, and the carrier will not slide sideways during the up-down movement of the moving carrier.

[0011] Further, the inner side wall of the cabinet is provided with a vertical guide rail arranged along the height direction thereof, and a vertical slider is slidably connected to the vertical guide rail in a clamping manner, and the vertical slider is connected to the side edge of the moving carrier. The stable up-down movement of the moving carrier is realized through the sliding cooperation of the vertical guide rail and the vertical slider, so as to ensure the stability of the carrier received on the moving carrier.

[0012] Further, support legs and balance plates are arranged at the four corners of the bottom of the cabinet. Through the cooperation of the support legs and the balance plates, the cabinet can be stably placed, so that the cabinet can well adapt to the working site and ensure the smooth production operation.

[0013] Compared with the prior art, the beneficial effects of the present application are that the structure is simple, reasonable and convenient to operate. The moving carrier is driven upward by the lifting cylinder until it is aligned with the upper layer of the double-layer conveying line, the carrier is automatically sent into the moving carrier, then the moving carrier is driven downward by the lifting cylinder until it is aligned with the lower layer of the double-layer conveying line, the electromagnet is started to magnetically attract and fix the iron slider, the chain drive assembly drives the chain to stably advance the push rod until the carrier on the moving carrier is pushed outward to the lower layer of the double-layer conveying line. The present application does not use the traditional belt conveying line transmission mode, but uses the independent working chain transmission assembly and the push rod to realize the automatic sending action of the carrier on the moving carrier. The carrier does not need the action of the push rod when it is sent into the moving carrier, so the push rod does not rise synchronously with the moving carrier, which simplifies the design and improves the conveying efficiency.
