Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical equipment technology, specifically relating to a blow molding mechanism for an upright infusion bag. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] Upright infusion bags are soft, highly malleable, flat bags. During infusion, as the medication flows out, the bag collapses and flattens under the influence of external atmospheric pressure, creating negative pressure inside. This allows infusion to be completed without the need for external air to enter, improving the airtightness and safety of the infusion process and reducing the risk of contamination. They are widely used in clinical infusion therapy.

[0004] In the production process of upright infusion bags, after the blow molding machine completes the molding of the upright infusion bag, the molded upright infusion bag needs to be removed from the mold and sorted out so that subsequent cleaning, filling and other processes can proceed smoothly.

[0005] The prior art discloses a bottle sorting device, including a limiting part and a bottle sorting turntable. An inner turntable is rotatably arranged inside the bottle sorting turntable. A rotating handle is connected to the center of the inner turntable. The rotating handle is threadedly connected to the bottle sorting turntable. The inner turntable includes multiple adjusting rods. The ends of the adjusting rods are connected to adjusting parts. A bottle storage tank is provided next to the adjusting parts. By rotating the rotating handle, the inner turntable and the bottle sorting turntable rotate relative to each other, and the size of the bottle storage tank is adjusted to sort bottles of different sizes.

[0006] However, it has the following drawbacks: The above solution is mainly applied to the filling and sorting of vials. Vials are rigid, small-capacity bottles that can be held in the storage slots of the vial unscrambler and rotate with it. However, it has the following drawbacks when sorting upright infusion bags: The bottle rotating tray has no height adjustment, and the thickness of the storage tank is limited. Meanwhile, the upright infusion bags are relatively tall. When the upright infusion bags rotate in the storage tank, there is a risk of them tipping over. In addition, the upright infusion bags and vials have different shapes and materials. The upright infusion bags are easily squeezed and deformed in the storage tank. The storage tank cannot guide the upright infusion bags, and the upright infusion bags are prone to being arranged in different directions when they are arranged in the storage tank. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a blow molding mechanism for an upright infusion bag, which can solve the technical problems of limited thickness of the storage tank in the prior art, easy tipping of the upright infusion bag, and inability to guide the upright infusion bag.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A blow molding mechanism for an upright infusion bag is provided, including a first turntable and an arc-shaped guide plate on one side of the outer periphery of the first turntable; a plurality of height adjustment pillars are connected to the top surface of the first turntable, and adjustment holes corresponding to the size, position and number of the height adjustment pillars are opened on the second turntable; The height adjustment support is a threaded rod. The height adjustment support is inserted into the adjustment hole and nuts are threaded onto the top and bottom surfaces of the second turntable to support the second turntable and adjust its height. The top surface of the second turntable is connected to several guide baffles. The arc-shaped guide baffles and the guide baffles form a guide channel. The guide baffles include guide groove plates, and the side of the guide groove plate with a rectangular guide groove faces the arc-shaped guide plate.

[0009] Preferably, the first turntable is connected to the arc-shaped guide plate on the worktable, a motor is installed on the worktable, and the output end of the motor is connected to the center of the bottom surface of the first turntable; multiple supports are connected between the arc-shaped guide plate and the worktable.

[0010] Preferably, the centers of the first turntable, the second turntable, and the arc-shaped guide plate are aligned.

[0011] Preferably, the guide baffle further includes an adjusting plate, which includes a groove plate and an abutment plate vertically connected to one end of the groove plate. The abutment plate is connected to the guide groove plate, and an adjusting groove is axially formed through the top and bottom surfaces of the groove plate.

[0012] Preferably, the second turntable also has several threaded holes, the width of the adjusting groove is equal to the diameter of the threaded hole, the adjusting plate is placed on the second turntable to align the adjusting groove with the threaded hole, and the limiting bolt passes through the adjusting groove and is threadedly connected to the threaded hole.

[0013] Preferably, the tail end of the limiting bolt is fixed with a limiting head, and the diameter of the limiting head is larger than the diameter of the threaded hole.

Both the first straight plate and the second straight plate are tangent to the arc-shaped guide plate, wherein the length of the first straight plate is greater than that of the second straight plate.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are: This invention utilizes a rectangular guide groove on a guide plate that works in conjunction with an arc-shaped guide plate to guide flat, upright infusion bags during rotation without compressing them. The second turntable is supported by an adjustable support column, which also rotates the second turntable. Furthermore, the height of the second turntable relative to the first turntable can be adjusted to regulate the height of the guide groove plate. This allows for support and guidance of upright infusion bags of varying heights, preventing them from tipping over. Attached Figure Description

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a blow molding mechanism for an upright infusion bag, such as... Figure 1 As shown, the system includes a first turntable 1 that rotates relative to the worktable, a second turntable 2 connected to the top surface of the first turntable 1, and several guide baffles 3 connected to the top surface of the second turntable 2. The guide baffles 3 are used to accommodate upright infusion bags. The system also includes an arc-shaped guide plate 5 fixedly connected to the worktable. The arc-shaped guide plate 5 is located on one side of the outer periphery of the first turntable 1, and the arc-shaped guide plate 5 and the guide baffles 3 form a guide channel 6 for the upright infusion bags. The first turntable 1 drives the second turntable 2 to rotate, thereby driving the several guide baffles 3 to rotate. When the guide baffles 3 rotate relative to the arc-shaped guide plate 5, they guide and prevent the upright infusion bags between the guide baffles 3 and the arc-shaped guide plate 5.

[0023] like Figure 1As shown, the top surface of the first turntable 1 is connected to the second turntable 2 by several height adjustment pillars 4. The several height adjustment pillars 4 are fixedly connected (by welding) to the top surface of the first turntable 1. Adjustment holes corresponding to the size, position and number of the height adjustment pillars 4 are opened on the surface of the second turntable 2. The adjustment holes of the second turntable 2 are aligned with the height adjustment pillars 4 of the first turntable 1 so that the height adjustment pillars 4 are inserted into the adjustment holes.

[0024] In this embodiment, the height adjustment support 4 is a threaded rod that passes through the second turntable 2. Nuts are threaded onto both the top and bottom surfaces of the second turntable 2. By adjusting the position of the nuts on the bottom surface of the second turntable 2, the height of the second turntable 2 relative to the first turntable 1 can be adjusted, thereby adjusting the height of the guide baffle 3 relative to the first turntable 1. It should be noted that there are various specifications for upright infusion bags. When the height of the upright infusion bag is relatively high, the height of the second turntable 2 relative to the first turntable 1 can be adjusted by adjusting the position of the nuts on the height adjustment support 4.

[0025] like Figure 1 As shown, the top surface of the second turntable 2 is connected to several guide baffles 3, and the guide baffles 3 include guide groove plates 31, such as... Figure 1 As shown, the guide plate 31 includes a horizontal plate. Along the circumference of the second turntable 2, both ends of the horizontal plate are fixedly connected to vertical plates (which can be integrally manufactured or welded). The two vertical plates and the horizontal plate together form a rectangular guide groove (i.e., the guide groove is opened on one side of the guide plate 31). The guide groove is set towards the arc-shaped guide plate 5. When the upright infusion bag enters the guide plate 31 and rotates with the guide plate 31 relative to the arc-shaped guide plate 5, the upright infusion bag can maintain the consistency of direction between the guide groove and the arc-shaped guide plate 5, and will not squeeze the upright infusion bag.

[0026] In this embodiment, the guide groove of the guide plate 31 cooperates with the arc-shaped guide plate 5 to guide the flat, upright infusion bag. This solves the technical problems in the prior art where the storage bottle tray squeezes the upright infusion bag, causing it to deform, and where the upright infusion bag cannot be guided.

[0027] In this embodiment, the second turntable 2 is supported by raising the support column 4. At the same time, the height of the guide plate 31 relative to the first turntable 1 can be adjusted by adjusting the height of the second turntable 2 relative to the first turntable 1. This can support and guide upright infusion bags of different heights. Most importantly, it can support taller upright infusion bags and prevent them from tipping over. This solves the technical problem in the prior art where the thickness of the storage tank is limited and the height of the upright infusion bag is relatively high, causing the upright infusion bag to tip over.

[0028] In this embodiment, the first turntable 1 is connected to the arc-shaped guide plate 5 on the workbench. The first turntable 1 is fixedly connected to the motor output end on the workbench. In one embodiment, the motor output end can be welded to the center of the bottom surface of the first turntable 1. The motor output end is perpendicular to the surface of the workbench. The motor housing can be bolted to the surface of the workbench, so that the first turntable 1 is parallel to the surface of the workbench. The arc-shaped guide plate 5 is connected to the workbench through multiple brackets. One end of the bracket is fixedly connected to the arc-shaped guide plate 5, and the other end of the bracket is fixedly connected to the workbench. In one specific embodiment, the arc-shaped guide plate is made of steel, the surface of the workbench is also made of steel, and the brackets are also made of steel. The arc-shaped guide plate 5, the brackets, and the surface of the workbench are fixedly connected by welding, wherein the arc-shaped guide plate 5 is perpendicular to the surface of the workbench.

[0029] It should be noted that the center of the second turntable 2 is the same as that of the first turntable 1, the center of the arc-shaped guide plate 5 is the same as that of the first turntable 1, and the diameter of the arc-shaped guide plate 5 is equal to the diameter of the first turntable 1.

[0030] like Figure 1 As shown, the guide baffle 3 also includes an adjustment plate 32. One end of the adjustment plate 32 is fixedly connected (which can be done by welding) to the guide groove plate 31, and the other end is connected to the top surface of the second turntable 2. The adjusting plate 32 is an L-shaped plate, including a groove plate. One end of the groove plate is fixedly connected to an abutment plate. The abutment plate is welded and fixed to the horizontal plate (the side without the vertical plate) of the guide groove plate 31. The abutment plate is perpendicular to the groove plate. An adjusting groove 321 is opened axially through the top and bottom surfaces of the groove plate. Several threaded holes are also opened on the second turntable 2. The width of the adjusting groove 321 is equal to the diameter of the threaded hole. After the adjusting plate 32 is placed on the second turntable 2 and the adjusting groove 321 is aligned with the threaded hole, the limiting bolt 322 passes through the adjusting groove 321 and is threadedly connected to the threaded hole. It should be noted that the tail end of the limiting bolt 322 is fixed with a limiting head. The diameter of the limiting head is larger than the diameter of the threaded hole. When the limiting bolt 322 is connected to the threaded hole, the limiting head cannot pass through the adjusting groove 321, thereby pressing the groove plate tightly against the surface of the second turntable 2, and thus pressing the adjusting plate 32 and the guide groove plate 31 tightly against the surface of the second turntable 2.

[0031] It should be noted that loosening the limiting bolt 322 to move the adjusting plate 32 away from the second turntable 2 allows adjustment of the position of the adjusting plate 32, thereby adjusting the position of the guide groove plate 31. When the guide groove plate 31 is adjusted towards the arc-shaped guide plate 5, the guide channel 6 becomes smaller; when the guide groove plate 31 is adjusted away from the arc-shaped guide plate 5, the guide channel 6 becomes larger. It is understandable that when handling larger upright infusion bags, the infusion bag not only becomes taller but also thicker. Adjusting the position of the adjusting plate 32 can accommodate upright infusion bags of different thicknesses.

[0032] In this embodiment, as Figure 1 As shown, each adjusting plate 32 is connected to the second turntable 2 by at least two limiting bolts 322. Along the axial direction of the adjusting groove 321, multiple limiting bolts 322 press the adjusting plate 32 onto the second turntable 2, which can prevent the adjusting plate 32 from rotating relative to the second turntable 2, so that the extension line of the adjusting groove 321 of the adjusting plate 32 connected to the second turntable 2 always passes through the center of the second turntable 2.

[0033] like Figure 1 As shown, several guide baffles 3 are evenly connected to the second turntable 2 in a circular array with the center of the second turntable 2 as the center; when the first turntable 1 rotates at a constant speed, the upright infusion bags can be guided and sorted one by one by the guide baffles 3 as they pass through the arc-shaped guide plate 5.

[0034] like Figure 1 As shown, several height adjustment supports 4 are evenly connected to the second turntable 2 in a circular array with the center of the second turntable 2 as the center. In this embodiment, the number of height adjustment supports 4 is at least three. The three height adjustment supports 4 can not only provide stable support for the second turntable 2, but also drive the second turntable 2 to rotate together with the first turntable 1.

[0035] like Figure 1 As shown, the height adjustment column 4 is positioned close to the center of the second turntable 2, while the limit bolt 322 is positioned close to the circumferential edge of the second turntable 2. The purpose of this arrangement is to prevent the height adjustment column 4 from interfering with the adjustment position of the adjustment plate 32.

[0036] like Figure 1 As shown, the two ends of the arc-shaped guide plate 5 are connected to the first straight plate 51 and the second straight plate 52, respectively. Both the first straight plate 51 and the second straight plate 52 are tangent to the arc-shaped guide plate 5. The first straight plate 51 is the feeding end, and the second straight plate 52 is the discharging end. The upright infusion bags reach the first straight plate 51 under the transmission of the feeding conveyor belt. Under the guidance of the first straight plate 51, they are driven by the guide baffle 3 through the arc-shaped guide plate 5, and finally sent to the discharging conveyor belt by the guidance of the second straight plate 52. The length of the first straight plate 51 is greater than that of the second straight plate 52. The reason for this setting is that there are many upright infusion bags during feeding, and the length of the first straight plate 51 needs to be relatively longer so that more upright infusion bags can stay at the first straight plate 51, be carried away by the guide baffle 3, and be sorted and guided by the arc-shaped guide plate 5.

[0037] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
