Description

Technical Field

[0001] The utility model relates to the technical field of medical product production, in particular to a bag-making interface clamp and a hard tube infusion bag production line. Background Art

[0002] The rigid tube infusion bag is welded by the bag body and the rigid tube interface, and the rigid tube interface needs to be welded with the bag body at the bag-making station. The rigid tube interface is a key component of whether the rigid tube infusion bag can be made and formed, and it is an important link to stably and reliably transport the rigid tube interface to the bag-making station. The existing equipment adopts an integrated clamp, which receives and transports the rigid tube interface to the bag-making station in a clamping manner. When the rigid tube interface is pressed into the bag-making interface clamp, the rigid tube interface will touch and rub against the inner wall of the clamp. Since the rigid tube interface is generally small in shape and the inner wall space of the bag-making interface clamp is relatively small, the inner wall of the clamp is not processed with high precision and is not easy to maintain. After the rigid tube interface rubs against the inner wall of the clamp, a large amount of wear debris will be generated. The wear debris will follow the clamp into the bag-making station and eventually enter the formed rigid tube infusion bag, affecting the product quality. Therefore, it is necessary to provide a clamp that can reduce the generation of wear debris and is easy to maintain to meet production needs. Utility Model Content

[0034] Please refer to Figures 1 to 3 The first pressing plate 32 and the second pressing plate 33 are located on the side of the connecting plate 31 away from the fixture base 20 , and the first pressing plate 32 and the second pressing plate 33 are fixedly connected to the connecting plate 31 .
