[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide a cart pusher, including a frame and a mounting bracket, the mounting bracket is fixed above the frame, a driving motor and a driving transmission shaft are provided on one side of the frame, and a driven shaft is provided on the other side; wherein, a driving wheel assembly and a guide rail assembly are provided at both ends of the frame, and a driven wheel assembly is provided at both ends of the driven shaft, and the driving wheel assembly and the driven wheel assembly are connected by a transmission chain; the guide rail assembly is composed of two relatively arranged U-shaped guide rails, and a guide roller is embedded in the U-shaped guide rail. A floating push head is provided on the transmission chain, and the driving motor drives the driving wheel assembly through the driving transmission shaft, so that the transmission chain drives the floating push head to perform linear motion together.
[0006] In the above-mentioned cart pusher, a starting position sensing switch is provided on one end of the frame close to the guide rail assembly, and an end position sensing switch is provided on the other end of the frame close to the guide rail assembly.
[0007] In the above-mentioned pusher, the guide roller is a combination roller, and the outer ring surface of the combination roller is hardened steel.
[0008] In the above-mentioned pusher, the driven wheel assembly and the driven wheel tensioning assembly are connected.
[0009] Compared with the existing technology, the present invention has the following beneficial effects: the cart pusher provided by the present invention replaces the linear track with a U-shaped guide rail and a combination roller, so that the chain and the combination roller are in a straight line, thereby avoiding the risk of the U-shaped guide rail and the combination roller falling off, and has a simple structure, is safe and reliable, and is easy to install and maintain.
