Automatic welding machine for medical drainage bag body

Abstract

The invention provides an automatic welding machine for a medical drainage bag body. The automatic welding machine comprises a film feeding frame mechanism, a welding mechanism and a traction mechanism, wherein the film feeding frame mechanism and the traction mechanism are positioned on two sides of the welding mechanism and are connected with the welding mechanism; the film feeding frame mechanism comprises a film feeding side plate, a film feeding correction assembly and a film feeding conveying assembly; the film feeding conveying assembly is assembled on a film feeding side plate of the frame; the film feeding correction assembly which is matched with the film feeding conveying assembly is arranged on the other side of the film feeding side plate; and one end of the assembled film feeding conveying assembly is connected with the welding mechanism. All actions in the scheme are automatically finished by a machine without manual work, and all shearing actions of the traction mechanism and all actions of the welding mechanism are performed simultaneously; moreover, the total time of finishing the lifting and shearing actions is shorter than the time of finishing all actions of the welding mechanism, and the working efficiency and the finished product quality are greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of drainage bag making machinery, in particular to an automatic welding machine for the body of a medical drainage bag. Background technique: [0002] At present, the commonly used drainage bag body welding machine is only manual or semi-automatic, only welding one at a time, and the outer dimensions of the bag body should be prefabricated. Such a drainage bag body welding machine has the following problems: 1. Because it is a manual or semi-automatic welding machine, it only welds one at a time, and the production efficiency is low; 2. Because it is a manual or semi-automatic welding machine, it needs to be manually unloaded, so the welding position The size of the bag is not uniform, and a little carelessness will cause product quality problems; 3. Because it is a manual or semi-automatic welding machine, the outer dimensions of the bag body should be prefabricated, which will increase the cost of the bag...

AI Technical Summary

Problems solved by technology

Such a drainage bag body welding machine has the following problems: 1. because it is a manual or semi-automatic welding machine, only one welding machine is welded at a time, and the production efficiency is low; The size of the bag body is not uniform, and a little carelessness will cause product quality problems; 3. Since it is a manual or semi-automatic welding machine, the outer size of the bag body must be prefabricated, which will increase the cost of the bag body; 4. If you do not use already Prefabricate the bag body with the outer size, and use the upper and lower layers of film to form the bag body by welding. Since it is a manual or semi-automatic welding machine, it will cause waste of materials and inaccurate dimensions; for drainage bags with scales, it will be easy. The scale is inaccurate, so the measurement is inaccurate; for the bag body with patterns, characters, points, and lines that are not symmetrically distributed, because it is a manual or semi-automatic welding machine, manual feeding is required, which is easy to cause patterns, characters, points, etc. , the orientation of the line is wrong

To sum up, these problems make this kind of drainage bag body welding machine low in production efficiency, inaccurate in size, easy to make mistakes in the pattern, text, point and line direction of the bag body, high in cost of the bag body, and difficult to maintain stable quality
