Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag rejection, in particular to a small packaging bag rejection machine. Background Art

[0002] The rejector is a device that removes unqualified products from the production line. The high-speed production line of packaging bags can generally pass 70 to 80 bags per minute, which is a relatively fast speed. Therefore, when removing the packaging bags containing products, the movement speed of the rejector must also be able to meet the requirements of the high-speed production line.

[0003] In the past, rejection equipment generally directly connected the rejection plate to the telescopic end of the cylinder, and used the telescopic push of the cylinder to push the packaging bag out of the production line. Because the production line runs fast, the cylinder needs to have a fast telescopic speed, which further causes a large impact force on the end of the cylinder. Long-term impact will affect the normal use of the cylinder and shorten the service life of the cylinder. At the same time, the telescopic stroke of the cylinder needs to be equal to the width of the production line, and there are requirements for the model of the cylinder, resulting in high cost of the cylinder. Therefore, a rejection machine for small packaging bags is designed to reduce the model requirements of the cylinder and the equipment cost of the cylinder, while shortening the rejection stroke and improving the rejection efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a rejection machine for small packaging bags. The telescopic cylinder controls the swing of the connecting rod and the sliding rod, thereby further controlling the meshing position of the gear on the upper rack. The meshing of the gear and the lower rack controls the movement of the lower rack, the sliding block and the rejection plate. The left and right movement of the rejection plate is utilized to control the rejection of small packaging bags, thereby shortening the movement stroke of the rejection plate and improving the rejection efficiency.

[0005] The utility model provides the following technical solution: a rejection machine for small packaging bags, comprising a frame and a conveyor, the upper end of the frame being located above the conveyor, and a rejection mechanism being installed on the upper end of the frame, the rejection mechanism being located above the conveyor and rejecting the packaging bags on the conveyor, the rejection mechanism comprising a swinging assembly, the swinging assembly being rotatably connected with a gear, the lower end of the frame being connected with an upper rack connecting plate, the lower end of the upper rack connecting plate being connected with an upper rack, a crossbeam being fixed below the frame, a lower slide rail being installed on the crossbeam, a sliding block being slid on the lower slide rail, a connecting plate being fixed on the sliding block, a lower rack being fixed to one end of the connecting plate, the gear being located between the upper rack and the lower rack, and a rejection plate being also fixed to one end of the connecting plate.

[0007] In order to shorten the movement stroke of the rejection plate, the rejection plate can perform rejection actions to the left and right. The rejection plate is located at the upper end of the conveyor and rejects the small packaging bags on the conveyor to the left and right.

[0008] In order to guide the rejected small packaging bags, baffles are fixed on the inner wall of the frame. The baffles are connected to the lower end of the beam and are located on both sides of the conveying frame.

[0009] In order to obtain information in advance and make the rejection action move synchronously when the small package bag enters the bottom of the rack, a code scanning component is also fixed on the side of the conveyor. The code scanning component is located above the conveyor and on one side of the rack for reading the information of the small package in advance.
