[0021] Referring Figure 1-2 as shown, it is a preferred embodiment provided by the present utility model.

[0022] The blood bag making device includes a film layer feeding structure for conveying two layers of film layers 101 arranged at an upper and lower interval, a spot welder 300 for performing spot welding on the two layers of film layers 101 to avoid deviation between the two layers of film layers 101, a bag head welder 500 for welding the head end fitting 204 between the head ends of the two layers of film layers 101, and a bag tail welder 600 for welding between the two layers of film layers 101 to form a closed loop edge. The area surrounded by the closed loop edge forms a blood bag.

[0023] For the above-provided blood bag making device, the two layers of film layers 101 are synchronously transmitted up and down through the film layer feeding structure. The spot welder 300 is used to perform spot welding on the two layers of film layers 101 to avoid deviation between the two layers of film layers 101. The bag head welder 500 is used to weld the head end fitting 204 between the head ends of the two layers of film layers 101. The bag tail welder 600 is used to weld between the two layers of film layers 101 to form a closed loop edge, and a blood bag is prepared. The entire bag making process is simple, realizing automatic bag making with high bag making efficiency.

[0024] Among them, during the process of welding the two layers of film layers 101 by the bag tail welder 600, a head end connection edge 202 is formed by welding between the head ends of the two layers of film layers 101, a tail end connection edge 203 is formed by welding between the tail ends of the two layers of film layers 101, and two side connection edges 201 are formed by welding between the side edges of the two layers of film layers 101.

[0025] The head end connection edge 202, the two side connection edges 201, and the tail end connection edge 203 are connected in a closed loop to form the above-mentioned closed loop edge. Among them, the head end fitting 204 is inserted into the head end connection edge 202 and is hermetically connected to the head end connection edge 202.

[0026] Among them, when the bag tail welding machine 600 welds two layers of film layers 101 to form a closed loop edge, the tail end catheter 205 can also be inserted between the two layers of film layers 101. Of course, according to the actual needs of the blood bag, the tail end catheter 205 does not need to be inserted.

[0027] In addition, the head end fitting 204 can be a head end catheter or other types of tube bodies, etc.

[0028] In this embodiment, the peripheral side of the blood bag has waste edge materials formed outside the sealing edge loop. The blood bag bag-making device includes a tearing edge structure 700 for tearing and separating the waste edge materials from the blood bag. Since the blood bag has an independent shape, after the blood bag is formed, the film layer 101 outside the closed loop edge forms waste edge materials, and the tearing edge structure 700 can be used to separate the waste edge materials from the blood bag.

[0029] Specifically, the tearing edge structure 700 includes a movable tearing edge chuck. After the tearing edge chuck clamps the waste edge materials, it moves away from the blood bag to tear and separate the waste edge materials from the blood bag.

[0030] In this embodiment, the blood bag bag-making device includes a finished product punching machine. The finished product punching machine punches and separates the waste edge materials from the blood bag. After using the finished product punching machine to separate the waste edge materials from the blood bag, the tearing edge structure 700 is used to tear and separate the waste edge materials away from the blood bag.

[0031] In this embodiment, the film layer feeding structure includes a plurality of film cylinders 100 and a film pulling structure 400 for synchronously driving two layers of film layers 101. The film layer 101 wound into a roll is wound on the film cylinder 100. When the film layer 101 on the film cylinder 100 is pulled out, the film layer 101 is flat. In this way, it is convenient to arrange the two layers of film layers 101 parallel to each other up and down, and by using the film pulling structure 400, synchronous driving of the two layers of film layers 101 can be realized, avoiding phenomena such as wrinkles.

[0032] A plurality of film pulling structures 400 are arranged outside the film layer 101 at intervals in sequence along the transmission direction of the film layer 101. By arranging a plurality of film pulling structures 400, synchronous pulling of the film layer 101 at multiple positions can be realized, so as to keep the film layer 101 with sufficient tensile force and maintain the synchronous transmission of the two layers of film layers 101.

[0033] In this embodiment, the film pulling structure 400 includes a driving chuck. The driving chuck is arranged on the synchronous belt. The driving chuck clamps the sides of the two layers of film layers 101, and the synchronous belt drives the driving chuck to move to drive the synchronous transmission of the two layers of film layers 101. The driving chuck can clamp the sides of the two layers of film layers 101, making the two layers of film layers 101 closer to each other, and synchronous transmission of the two layers of film layers 101 can be realized.

[0034] In addition, the film pulling structure 400 also has an automatic deviation correction structure, which detects the side edges of the film layer 101 through sensors to determine whether the film layer 101 is deviated. If there is a deviation, timely deviation correction is performed.

[0035] In this embodiment, outside the bag head welding machine 500 and the bag tail welding machine 600, there are respectively a manipulator for grasping the head end fitting 204 or the tail end conduit 205, a tooling table for fixing the head end fitting 204 or the tail end conduit 205, and a core pin for inserting the head end fitting 204 or the tail end conduit 205. The core pin moves to place the head end fitting 204 between the head ends of the two film layers 101, or to place the tail end conduit 205 between the tail ends of the two film layers 101.

[0036] After the manipulator grasps the head end fitting 204 or the tail end conduit 205, it places the head end fitting 204 or the tail end conduit 205 on the tooling table. The tooling table moves to insert the head end fitting 204 or the tail end conduit 205 onto the core pin, and the core pin moves, thereby achieving placing the head end fitting 204 between the head ends of the two film layers 101, or placing the tail end conduit 205 between the tail ends of the two film layers 101.

[0037] In this embodiment, the blood bag bag-making device is provided with a CCD detection structure, and through the CCD detection structure, image recognition detection and the like can be performed on some specific links in the blood bag bag-making process.

[0038] The blood bag bag-making device has a blowing structure, and the blowing structure blows ion wind towards the film layer 101 to eliminate static electricity and remove dust from the film layer 101.

[0039] The spot welder 300 is provided with a partial punching machine, and the partial punching machine performs partial punching on the two film layers 101.

[0040] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
