Description

Technical Field

[0001] The invention relates to the technical field of bottle cap detection, and in particular to an air tightness detection system for bottle caps. Background Art

[0002] Bottle caps are an important part of food and beverage packaging, and are also the first place where consumers come into contact with products. Bottle caps have the function of keeping the contents of the product sealed, and also have the functions of anti-theft opening and safety. Therefore, they are widely used in bottled products. Therefore, bottle caps are the upstream industries of food, beverage, wine, chemical industry, and pharmaceutical industry, and are key products of bottle container packaging. Bottle caps need to go through a series of testing processes after production, among which airtightness testing is an important part. The quality of airtightness is directly related to the shelf life of food.

[0003] Currently, the degree of automation of bottle cap inspection is low, and continuous inspection cannot be performed. Bottle caps need to be manually stacked on the inspection equipment for inspection, and air pressure inspection is usually used. The bottle caps are not dusted before inspection, and dust adheres to the bottle cap interface, which can easily affect the sealing and thus affect the airtightness inspection.

[0017] 1. By installing the material tray, turntable, hanger and clamping mechanism, the right material tray is pushed out of the machine cover through the right electric slide rail, and multiple bottle caps are inserted into the two rows of plugs and sent into the machine cover. The rotating column drives the turntable to rotate, and the empty clamping mechanism is turned to the right. The corresponding first electric push rod is started to drive the hanger to move down, and the second electric push rods on both sides are started. The two pairs of clamps are driven to move toward each other through the connecting arm, and the caps of multiple bottle caps are clamped synchronously through multiple pairs of arc-shaped clamps to realize automatic loading, and can go through dust removal, detection and unloading in turn to realize continuous dust removal and air tightness detection process, with high degree of automation and high detection efficiency.

[0018] 2. By installing two rows of dust exhaust cylinders, air blowing pipes and dust exhaust channels, the two rows of bottle caps clamped are turned to the front side, and the bottle caps are lowered onto the two rows of dust exhaust cylinders through the first electric push rod. The air blowing pipes are inserted into the corresponding bottle caps, and air is blown to the two rows of air blowing pipes through the main pipe and the branch pipes. The gas is blown to the inner top of the bottle cap and then blows around. The airflow flows downward along the cover wall, and the dust adhering to the cover wall and the cover mouth wall is blown away, and the dust is discharged into the dust exhaust channel through the dust exhaust cylinder and the dust exhaust port. Dust can be removed before detection to ensure detection accuracy.

[0019] 3.

The limit plate limits the top of the bottle caps. Before sealing, the cylinder is started first, and multiple connecting rods are driven to move downward synchronously through the connecting plate, thereby pulling multiple pistons downward, and the gas is sucked into the air cavity through the suction pipe. After sealing, multiple pistons move upward to squeeze the gas into the bottle caps through the air inlet pipe and the air inlet hole. The cap is inflated synchronously, and the amount of inflated gas remains consistent. If the airtightness of the bottle cap is normal, the air pressure inside the bottle cap and the air inlet is relatively large, and the air pressure squeezes the eardrums on both sides, and then pulls the spring through the resisting rod, driving the trigger plate to resist the trigger switch, and the trigger switch turns on to send an electrical signal, indicating that the airtightness is good. If there is a problem with the airtightness and the gas inside the bottle cap leaks, the air pressure is not enough to drive the eardrum, and the trigger switch is not turned on. The detection speed is fast, and the detection data is displayed by the detection light on the discharge side through the controller for easy removal. BRIEF DESCRIPTION OF THE DRAWINGS

Before sealing, the cylinder 22 is started first, and the multiple connecting rods 23 are driven to move downward synchronously through the connecting plate 15, thereby pulling the multiple pistons 27 downward, and the gas is sucked into the air cavity 24 through the suction pipe 25. After sealing, the multiple pistons 27 move upward, and the gas is squeezed into the bottle cap through the intake pipe 26 and the intake hole 28. The two rows of bottle caps are inflated synchronously, and the amount of gas inflated is kept constant. The air pressure squeezes the eardrums 29 on both sides, and then pulls the spring 33 through the push rod 32, driving the trigger plate 34 to resist the trigger switch 31, and the trigger switch 31 is turned on to send an electrical signal, indicating that the airtightness is good. If there is a problem with the airtightness and the gas inside the bottle cap leaks, the air pressure is not enough to drive the eardrum 29, and the trigger switch 31 is not turned on. The detection speed is fast, and the detection data is displayed by the detection light 35 on the discharge side through the controller, which is convenient for rejection.
