Lid-pressing device

Abstract

The invention provides a lid-pressing device. The lid-pressing device comprises a conveyor belt for conveying a bucket body and rollers located above the conveyor belt for pressing a bucket lid when the bucket body and the bucket lid pass through supports. The rollers are installed on the supports. The supports straddle the conveyor belt. The conveyor belt is driven by a motor. Since a deflection included angle Theta allowing the bucket body to pass through exists between the conveyor belt and a roller plate, 7 degrees <= Theta <= 15 degrees, so that the rollers roll on the bucket lid during pressing. In this process, the air is gradually exhausted, so that air blowing phenomenon does not happen to the bucket lid, and the bucket is easier to stack while being stacked and transported. In addition, the pressure to the bucket body is gradually increased, so that under the same conditions, the bucket can be protected from damage to the maximum extent during a pressing process. The lid-pressing device of the invention is simple in structure and ingenious in conception. The device only needs to rotate the conveyor belt at runtime, and the rollers can press the lid without any power. Therefore, the running cost is reduced.

Description

technical field [0001] The invention relates to the field of capping machinery, in particular to a capping device. Background technique [0002] Plastic drums have long been used as packaging containers for sales terminals such as lubricants, paints, and coatings. During production, first put a certain amount of lubricating oil, paint, etc. into a plastic bucket, then put the lid on the bucket, and finally press down the lid hard, using the elasticity of the plastic, the barb on the bucket is hooked on the bucket The cap is fitted with corresponding barbs to form an interlock, thereby completing the encapsulation process of lubricants, paints, etc. In the prior art, the capping machines are all pneumatic or hydraulic devices, which press-fit the bung vertically from top to bottom. [0003] This kind of capping machine has the following disadvantages: 1. During the capping process, the gas in the barrel is not easy to be removed, and the upper part of the barrel lid is easy...

AI Technical Summary

Problems solved by technology

[0003] This kind of capping machine has the following disadvantages: 1. During the capping process, the gas in the barrel is not easy to be removed, and the upper part of the barrel lid is easy to cause gas blowing, which cannot be stacked or transported, and will eventually occupy a lot of space, increasing the working area and site costs; 2. .The power of the machine is not easy to control. When it is too large, it is easy to crush the barrel body, so the capping time is prolonged and the production efficiency is reduced; 3. The capping is often done manually, and the worker operates the capping machine. One operation is completed One-time capping operation; although automatic capping can also be realized through circuit control to save manpower, the control system is complicated and the cost is high
