The carton separating and strutting device of claim 4, characterized in that the carton conveying belt further comprises a carton pressing plate, a friction cushion block and a carton guardrail, wherein the carton guardrail is arranged at two sides of the synchronous belt and used for laterally protecting the carton; one end of the carton pressing plate is slidably mounted on the carton guardrail, the other end of the carton pressing plate extends to the position above the synchronous belt, the friction cushion block is connected to the bottom of the carton pressing plate, the bottom of the friction cushion block is in contact with the synchronous belt to generate friction force, so that the friction cushion block and the carton pressing plate are driven to move forwards along with the synchronous belt, and the friction cushion block presses the carton from the back of the carton queue to prevent the carton from collapsing.

6. The carton box separating and erecting device as recited in claim 5, wherein said timing belt is made of polyurethane material, and said friction pad is made of polyurethane material.

7. The carton separating and spreading device according to claim 5, wherein the carton guardrail is provided with a slide rail and a guide rod parallel to the running direction of the synchronous belt, the slide rail is provided with a slide block capable of moving along the slide rail, the slide block simultaneously passes through the guide rod to enable the slide block to slide on the slide rail along the guide rod, and one end of the carton pressing plate is slidably mounted on the carton guardrail through the slide block.

8. The carton separating and spreading device according to claim 1, wherein a supporting plate abutting against the lower baffle is further disposed at a terminal end of the carton conveying belt, the supporting plate is connected with a supporting plate cylinder, the supporting plate cylinder drives the supporting plate to extend and retract along a direction of the carton conveying belt, when the supporting plate extends, a carton comes onto the supporting plate, when the supporting plate retracts, a gap capable of accommodating a single carton is formed between the carton conveying belt and the lower baffle, and the upper baffle is pressed down to press the carton originally on the supporting plate into the gap.

9. The carton separating and erecting device as recited in claim 1, wherein said lower baffle is L-shaped with an opening facing the carton conveyor, and when the lower baffle moves downward, the lower baffle and the end of the carton conveyor form a space for accommodating a single carton, so that the sheet carton can smoothly fall onto the lower baffle by pressing down the upper baffle.

10. The carton separating and erecting device according to claim 1, wherein said upper baffle plate driving mechanism and/or said lower baffle plate driving mechanism is an air cylinder.
