Description

Technical Field

[0001] This utility model relates to the field of assembly line production technology, specifically to a defective can cap rejection mechanism for assembly lines. Background Technology

[0002] Automated production lines are a highly efficient and reliable production method that significantly improves production efficiency and product quality, enhances the adaptability and flexibility of production lines, and also improves production safety and environmental friendliness. The significance of automated production lines lies in helping enterprises improve production efficiency and competitiveness, promoting industrialization and informatization, and achieving sustainable development.

[0003] Can lid production is typically completed on an assembly line, during which can lids need to be inspected to remove defective ones. This is done using a visual inspection device, and the can lids are then removed once they reach the rejection position. However, because the conveyor belt is constantly moving, the spacing between the can lids on the conveyor belt varies. When a defective can lid detected at the inspection position reaches the rejection position, its position may be off, resulting in it not being rejected and thus having low accuracy. To address this, we propose a defective can lid rejection mechanism for assembly lines. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a defective can cap rejection mechanism for production lines. The mechanism uses an intermittent belt conveyor to achieve fixed-distance transport of can caps, making the rejection of defective can caps more accurate and effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a defective can cap rejection mechanism for a production line, comprising a belt conveyor and an intermittent transmission mechanism;

[0006] Intermittent transmission mechanism: It includes a mounting plate, a drive gear, a lever, a half gear, and a transmission assembly. The mounting plate is fixedly connected to the rear end of the support frame of the belt conveyor. The front end of the left side of the mounting plate is rotatably connected to the drive gear via a rotating shaft one. The middle of the left side of the mounting plate is rotatably connected to the half gear via a rotating shaft two. The drive gear and the half gear are meshed. The left edges of the drive gear and the half gear are bolted to a lever. The lever of the half gear is located in the middle of the smooth outer arc surface of the half gear. The transmission shaft at the rear of the belt conveyor is driven by the transmission assembly. The intermittent belt conveyor realizes the fixed-distance transport of can lids, making the rejection of defective can lids more accurate.

[0007] Furthermore, it also includes a control box, which is fixedly connected to the left side of the mounting plate. The control box contains a controller, the input of which is electrically connected to an external power source to control electrical appliances.

[0008] Furthermore, the intermittent transmission mechanism also includes a motor, which is fixedly connected to the right side of the mounting plate. The output shaft of the motor is fixedly connected to the right end of the rotating shaft, and the input end of the motor is electrically connected to the output end of the controller to drive the drive gear to rotate.

[0009] Furthermore, the transmission assembly includes a first transmission gear, a second transmission gear, a first synchronous pulley, and a second synchronous pulley. The first transmission gear is fixedly sleeved on the outer side of the right side of the rotating shaft. The second transmission gear and the first synchronous pulley are rotatably connected to the rear end of the left side of the mounting plate via a third rotating shaft. The first transmission gear and the second transmission gear are meshed together, and the number of teeth of the first transmission gear is greater than the number of teeth of the second transmission gear. The second synchronous pulley is fixedly sleeved on the left end of the rotating shaft on the rear side of the belt conveyor. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt to achieve transmission.

[0010] Furthermore, the intermittent transmission mechanism also includes a protective cover. The protective cover is fixedly connected to the left side of the mounting plate. The drive gear, lever, half gear, transmission gear one, transmission gear two, synchronous pulley one and synchronous pulley two are all located inside the protective cover to protect the internal parts.

[0011] Furthermore, a mounting base is bolted to the front end of the right side of the belt conveyor, and a cylinder is fixedly connected to the upper surface of the mounting base. The telescopic end of the cylinder corresponds to the left and right positions of the belt of the belt conveyor, and the air inlet of the cylinder is connected to the air outlet of an external air pump to remove the can lid.

[0012] Furthermore, a support base is bolted to the right side of the upper surface of the mounting base, and a photoelectric switch is installed on the left side of the support base. The photoelectric switch corresponds to the vertical position of the belt of the belt conveyor, and the photoelectric switch is bidirectionally electrically connected to the controller to detect whether the can lid has been rejected.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This defective can cap rejection mechanism for production lines has the following advantages:

[0014] During startup, the motor's output shaft drives the drive gear to rotate. The drive gear rotates twice, and the half gear rotates once. Through the transmission of various components of the transmission assembly, the belt conveyor achieves intermittent transmission. When a defective can lid is conveyed to the position of the cylinder, the cylinder's extension end pushes out, removing the defective can lid. A photoelectric switch detects whether the defective can lid has been pushed off. During intermittent belt transmission, the motor runs continuously, avoiding frequent start-stop of the motor and extending its service life. At the same time, the distance between can lids remains constant, and the position of the can lid does not change when it is conveyed to the detection position and the rejection position, making rejection more accurate.
