Automatic welding equipment for plastic barrel cover and oil nozzle

Abstract

The invention discloses automatic welding equipment for a plastic barrel cover and an oil nozzle and belongs to the field of automatic equipment. The automatic welding equipment disclosed by the invention comprises a frame and a barrel cover clamping and conveying device; a barrel cover feeding station, a barrel cover positioning station, an oil nozzle mounting station, a welding station, a detecting station and a discharging station are arranged in sequence on the barrel cover clamping and conveying device and along a rectilinear direction; a barrel cover feeding device is arranged at the barrel cover feeding station; a barrel cover rotary positioning device is arranged at the barrel cover positioning station; an oil nozzle positioning and mounting device is arranged at the oil nozzle mounting station; an ultrasonic welding device is arranged at the welding station; an air tightness detecting device is arranged at the detecting station; and a discharged material stacking device and an inferior-quality product recycling device are arranged at the discharging station. The automatic welding equipment disclosed by the invention can sequentially automatically accomplish the work of barrel cover feeding, barrel cover positioning, oil nozzle positioning and mounting, welding, air tightness detection and discharged material stacking, and is simple and compact in structure, stable and reliable in operation, flexible and convenient to control, high in production efficiency and good in welding quality.

Description

Technical field [0001] The invention relates to an automatic production equipment for plastic barrel lids, and more specifically, to an automatic welding equipment for plastic barrel lids and oil nozzles. Background technique [0002] In liquid packaging containers, in order to facilitate the pouring of liquids, a grease nipple is usually provided on the plastic lid of the container, and the liquid material in the container can be conveniently used through the grease nipple. The plastic drum cover and the oil nozzle are usually welded and connected by an ultrasonic welding machine. Most of the welding machines for the plastic drum cover and the oil nozzle in the prior art are semi-automatic, requiring the operator to manually place the oil nozzle on the plastic drum lid and then put the plastic The lid is placed on the jig, and the ultrasonic welding device is driven by the pressure cylinder above the jig for welding. Due to the manual feeding, the production efficiency is very l...

Problems solved by technology

[0004] 1. The equipment on each station is very close to each other, which is easy to cause equipment work interference, and it is impossible to further increase the feeding and discharging system to increase the storage capacity; at the same time, in order to cooperate with the split turntable system, more matching components need to be set, such as The five stations of the split turntable system need to be equipped with rotating motors, etc., which makes the equipment structure very complicated and is not conducive to equipment troubleshooting

[0005] 2. Using the split turntable system, adding processing stations on it is very limited, and generally can only be used in occasions with fewer processing stations.

When adding processing stations, it is necessary to increase the diameter of the split turntable system, resulting in larger and bloated equipment, making the operation and control of the equipment more cumbersome
