[0013] The working principle and beneficial effects of the present invention are:

[0014] 1. By setting the limiter, when multiple conveyor rollers are conveying cartons to move them, when the carton needs to reach the specified position, the first hydraulic cylinder can be started first, and the output end of the first hydraulic cylinder drives the baffle to extend from between the two conveyor rollers. The baffle is located at the front end of the carton movement, so that the carton is resisted when it contacts the baffle and stops moving. Then, the two third hydraulic cylinders are started, and the two third hydraulic cylinders respectively drive a pressing plate to clamp the two sides of the carton, so as to calibrate it, so that the carton can be accurately moved to the specified position, so that the carton can be accurately loaded, so as to facilitate the accuracy of subsequent coding;

[0015] 2. By setting up the cooperation of the second hydraulic cylinder and other parts, when the carton is blocked by the baffle, the second hydraulic cylinder is started, and the output end of the second hydraulic cylinder drives the connecting plate to drive the first inclined plate to move upward. Since the carton is resisted by the baffle during the forward movement and hits the baffle, it is easy to move backward. Therefore, the upward movement of the first inclined plate can form a thrust on the carton through the inner inclined surface, so that it can move to the specified position, thereby further improving the accuracy of carton loading;

[0016] 3. By arranging the cooperation of the second spherical rod and other parts, when the connecting plate moves upward, the second spherical rod contacts the inclined groove, thereby pushing the cylinder to drive the latch to move out of the inner fixing hole of the circular ring, so that the circular ring is no longer fixed. The above steps are reversed to fix the circular ring, so that when the circular ring is no longer fixed, the first spherical rod contacts the inclined surface when the connecting plate continues to move upward, and the power plate drives the L-shaped push rod to move horizontally under the action of the inclined surface, thereby pushing the auxiliary roller to move horizontally, so that the first inclined plate can correct the carton that has retreated too far, thereby improving the overall practicality of the device;

[0017] 4. By setting the cooperation of the first spherical rod and other parts, when the first inclined plate moves laterally, the first spherical rod abuts against the plane on one side of the power rod and stops moving laterally, the third spherical rod moves upward and contacts the inclined surface on one side of the second inclined plate, and the spur gear is pushed to move in the direction of the first inclined plate under the action of the second inclined plate, and then the spur gear is driven to drive the first inclined plate to rotate through the rotating shaft, so that the first inclined plate can actively push the deviated carton to reset during the process of rising from the bottom of the auxiliary roller to the top of the auxiliary roller, thereby further improving the accuracy of carton feeding, thereby ensuring the accuracy of subsequent coding.

DETAILED DESCRIPTION

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0034] First, the labeler 12 is composed of existing structures for labeling, such as a mechanical arm, a label suction plate, and a labeling plate. Since the composition of the labeler 12 is a prior art, it will not be described in detail here; the multiple conveying rollers 4 can be synchronously driven by chains and gears, and the conveying rollers 4 are driven by a motor, so that after the carton 3 is placed on the conveying rollers 4, it can be conveyed to the position of the labeler 12 by the multiple conveying rollers 4 for labeling;

[0035] When multiple conveying rollers 4 are conveying the carton 3 to move it, when the carton 3 needs to reach the specified position, the first hydraulic cylinder 806 can be started first, and the output end of the first hydraulic cylinder 806 drives the baffle 804 to extend from between the two conveying rollers 4. The baffle 804 is located at the front end of the movement of the carton 3, so that the carton 3 encounters resistance when it contacts the baffle 804 and stops moving. Then, the two third hydraulic cylinders 10 are started, and the two third hydraulic cylinders 10 respectively drive a pressing plate 11 to clamp the two sides of the carton 3, so as to calibrate it, so that the carton 3 can be accurately moved to the specified position, so that the carton 3 can be accurately loaded, so as to facilitate the accuracy of subsequent coding;

[0036] When the forward movement of the carton 3 is blocked by the baffle 804, the second hydraulic cylinder 807 is started, and the output end of the second hydraulic cylinder 807 drives the connecting plate 808 to drive the first inclined plate 803 to move upward. Since the carton 3 encounters resistance from the baffle 804 during its forward movement and collides with the baffle 804, it is easy to move backward. Therefore, the upward movement of the first inclined plate 803 can form a thrust on the carton 3 through the inner inclined surface, so that it can move to the specified position, thereby further improving the loading accuracy of the carton 3.

[0039] When the connecting plate 808 moves upward, the second spherical rod 703 contacts the inclined groove 706, thereby pushing the cylinder 701 to drive the pin 704 to move out from the inner fixing hole of the ring 609, so that the ring 609 is no longer fixed.
