DETAILED DESCRIPTION

[0027] The utility model will be further described in combination with specific embodiments.

[0028] As shown in Figure 1 and Figure 2 The automatic edge-tearing mechanism for medical liquid bag production comprises a conveying station 1, a cutting station 2 and an edge-tearing station 3.

[0029] The conveying station 1 is used to convey the medical liquid bag to be subjected to edge-tearing treatment to the cutting station 2 and convey the medical liquid bag cut by the cutting station 2 to the edge-tearing station 3 for edge-tearing, and finally convey the medical liquid bag to discharge after the edge-tearing work is completed.

[0030] Specifically, the conveying station 1 comprises a conveying belt 11 arranged in a straight line, and the cutting station 2 and the edge tearing station 3 are arranged on the sides of the conveying belt 11 in sequence. The conveying station 1 further comprises two pressing plates 12 which can move back and forth along the conveying belt 11, and the two pressing plates 12 are used to stably press the medical liquid bag on the conveying belt 11 for conveying, so as to prevent the medical liquid bag from being stacked, lifted or otherwise affected, so as to affect the subsequent production operation. In this embodiment, the two pressing plates 12 can press and convey two medical liquid bags in front and back, and in other embodiments, the specific number of the pressing plates 12 can be arranged according to the situation. In addition, the pressing plate 12 is connected with a track arranged below the conveying belt 11 through a transmission connection to realize horizontal movement, and is connected with a motor through a transmission connection to realize lifting.

[0031] The cutting station 2 comprises a first fixing assembly 21 and a cutting assembly 22, wherein the first fixing assembly 21 is used to fix the medical liquid bag conveyed to the position, and the cutting assembly 22 is responsible for cutting the waste edge of the fixed medical liquid bag for the first time.

[0032] As can be seen from the figure, the first fixing assembly 21 comprises a first chuck 23 arranged on the side of the conveying belt 11, and in this embodiment, the first chuck 23 has two. The first fixing assembly 21 further comprises a first fixing plate 24 arranged above the conveying belt 11, and similarly, the first fixing plate 24 also has two, but differently, the two first chucks 23 are arranged along the conveying direction of the conveying belt 11, and the two first fixing plates 24 are perpendicular to the arrangement direction of the first chucks 23, that is, the long edges are arranged along the conveying direction of the conveying belt 11. The purpose of such arrangement is that, first, the first fixing plate 24 also serves to press the medical liquid bag flat from above, because the first chuck 23 needs to fix the end of the medical liquid bag in order to facilitate the cutting assembly 22 to cut the waste edge of the medical liquid bag for the first time, and therefore, under the condition that the end of the medical liquid bag is fixed, the two first fixing plates 24 arranged in this way can complete the pressing of the medical liquid bag from the transverse direction as much as possible, so as to ensure the pressing effect.

[0033] The cutting assembly 22 comprises scissors 25 arranged on the side of the conveying belt 11, and in most embodiments, the scissors 25 need to be provided with two and arranged on the left side of the first first chuck 23 and the right side of the second first chuck 23 respectively, so that the first medical liquid bag entering the cutting station 2 can have its left waste edge cut by the first scissors 25 after the end thereof is fixed by the first first chuck 23, and then conveyed downward, and the right waste edge thereof can be cut by the second scissors 25 after the end thereof is fixed by the second first chuck 23, and at the same time, the left waste edge of the next medical liquid bag can be cut by the first scissors 25, so as to realize simultaneous operation of multiple stations and improve work efficiency.

[0034] The edge tearing station 3 comprises a second fixing assembly 31 and an edge tearing assembly 32. In the embodiment, the second fixing assembly 31 comprises three second fixing plates 33 arranged in the length direction perpendicular to the conveying direction of the conveying belt 11. The three second fixing plates 33 together form two edge tearing areas 34, so that in the embodiment, two first clamps 23 correspond to the two edge tearing areas 34, and the edge tearing operation of two medical liquid bags can be simultaneously performed.

[0035] As can be seen from the figure, a mounting table is arranged below the conveying belt 11. The second fixing plates 33 are driven to ascend and descend by a motor and a transmission assembly arranged on both sides of the conveying belt 11. Thus, the medical liquid bags being subjected to the edge tearing operation can also be pressed to ensure stability.

[0036] The edge tearing assembly 32 comprises a guide rail 34 arranged above the conveying belt 11. A sliding table 35 is arranged on the guide rail 34. The moving direction of the sliding table 35 on the guide rail 34 is perpendicular to the conveying direction of the conveying belt 11. Therefore, the sliding table 35 can be regarded as being capable of moving close to and away from the conveying belt 11 in the direction perpendicular to the conveying direction of the conveying belt 11. A liftable connecting block 36 is arranged at the bottom of the sliding table 35. A second clamp 37 is rotatably connected to the connecting block 36 through a rotating shaft. In the embodiment, the second clamp 37 has two, and is arranged at the central axis of the two edge tearing areas respectively, for clamping the end of the medical liquid bag.

[0037] When the edge tearing is performed, only the end of the medical liquid bag needs to be clamped by the second clamp 37. Then, the sliding table 35 is driven to lift the end of the medical liquid bag by the second clamp 37. At this time, since the two side edges of the medical liquid bag have been fixed by the second fixing plates 33, as the end of the medical liquid bag is slowly lifted, the cutting line between the main body and the waste edge of the medical liquid bag will be easily torn, and the edge tearing is completed.
