Bag body filling type infusion product filling and sealing equipment

Abstract

The invention discloses filling and sealing equipment of a bag-body filling type infusion product. The filling and sealing equipment comprises a rack main body, wherein the rack main body is sequentially provided with a bag receiving and opening blowing mechanism, a bag-opening sealing and filling mechanism, a tail-edge welding mechanism and a bag outputting mechanism. All the mechanisms realize function continuity by a ring-shaped main driving mechanism and a filling and sealing clamp arranged on a ring-shaped synchronous belt; the bag receiving and opening blowing mechanism utilizes vacuum to layer co-extrusion films at a non-welding area at the tail part of a bag body and utilizes the blowing pressure of clean gas to eliminate the stress of sticking of the co-extrusion films; and after the bag opening is finished, infusion bags are conveyed to a filling station, a tail-part welding station and a bag outputting station in sequence through the main driving mechanism to finish corresponding filling, welding and outputting actions. The filling and sealing equipment disclosed by the invention has the advantages that the difficulty of bag opening in filling is reduced, the probability of residue of liquid medicines at the opening of non-hot-pressing area is reduced, and the bubbles generated by the subsequent tail-part welding due to residue of the liquid medicines on the co-extrusion films are effectively avoided, so that the welding quality is guaranteed.

Description

technical field [0001] The invention belongs to the field of flexible packaging pharmaceutical machinery, in particular to a bag body filling type transfusion product filling and sealing equipment. Background technique [0002] The bag body filling infusion product is a newly developed flexible packaging infusion product in China. This product is composed of a nozzle with a self-sealing function and a non-PVC multi-layer co-extrusion film through certain technical means. Inside the infusion bag bag. Bag body filling type infusion bag The liquid filling port of the bag body is located on any side of the infusion bag body, which is formed by reserving a non-thermal pressure area on any side of the bag body. [0003] At present, bag-making and filling-sealing equipment developed for the production process of bag-filled flexible packaging infusion products has appeared on the market. In the production process of bag-filled non-PVC infusion bags, the key point is to Reserve a n...

Problems solved by technology

[0003] At present, bag-making and filling-sealing equipment developed for the production process of bag-filled flexible packaging infusion products has appeared on the market. In the production process of bag-filled non-PVC infusion bags, the key point is to Reserve a non-hot-pressing area on either side to open the bag, and clamp and fix the tail-filled non-PVC infusion bag after bag making is completed, while the existing bag-filling non-PVC infusion bag filling and sealing equipment adopts simple The bag opening method of the sucker adsorption method has a poor bag opening effect, and it is difficult to meet the requirements of the production process of the bag body filling non-PVC infusion bag. The tool uses a gear mechanism to adjust the distance between the two sliding brackets. It is necessary to set up a set of pushing devices in multiple processes to complete the action of the gear mechanism, and the structure is more complicated.
