[0001] This utility model belongs to the field of pharmaceutical equipment technology, specifically relating to a conveying device for low-density polyethylene ampoules. 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] Plastic ampoules are sterile injectable formulation packaging produced using blow-fill-seal (BFS) three-in-one technology. Their raw materials are mostly low-density polypropylene (PP) or polyethylene (PE) plastic particles. Compared with traditional glass ampoules, plastic ampoules have advantages such as no glass detachment, less breakage, and easier opening.

[0004] In the production process of polyethylene ampoules, the labeling process is also crucial, such as... Figure 1 As shown, polyethylene ampoules are typically conveyed to the labeling machine's dispensing track by a conveyor belt. However, currently, low-density polyethylene ampoules are usually produced in a continuous sheet, meaning multiple ampoules are connected together. When these continuous sheets of polyethylene ampoules are conveyed to the labeling machine, they often curl up on the conveyor belt, forming an egg roll shape. This causes the ampoules to stack and compress on the conveyor belt, preventing them from being properly conveyed to the labeling machine's dispensing track. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a conveying device for low-density polyethylene ampoules, which can solve the technical problem in the prior art that polyethylene ampoules arranged in whole plates are stacked and squeezed on the conveyor belt and cannot be properly conveyed to the dispensing track of the labeling machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A conveying device for low-density polyethylene ampoules is provided, comprising a conveyor belt rotatably connected between two guard plates; along the axial direction of the conveyor belt, each guard plate is connected to a guide guard by a plurality of guard rail connectors, the bottom end of the guide guard maintaining a set distance from the top surface of the conveyor belt; the guide guard is used to guide the polyethylene ampoules on the conveyor belt. A guide plate is installed between two guide rails. The guide plate is connected to the outside of one of the guide rails by multiple plate connectors to level the passing polyethylene ampoules. The guide plate includes a guide plate and a pressure plate, wherein the guide plate is connected at a set angle to the end of the pressure plate facing the polyethylene ampoule, and the included angle between the guide plate and the pressure plate is an obtuse angle, and the range of the obtuse angle is 135°-160°.

[0007] Preferably, the top of the guard plate is flush with the top surface of the conveyor belt, and the bottom ends of the guard plates are connected by a flat plate, which is connected to the top of the four support legs, and the bottom ends of the support legs are connected to the ground.

[0009] Preferably, a vertical first threaded hole is formed at the top of the vertical block of the first connecting block, the first threaded hole is connected to the adjustment hole, and the first locking bolt is connected to the internal thread of the first threaded hole.

[0010] Preferably, the pressure plate connector includes a second connecting block and a third connecting block. The second connecting block is connected to the outside of the guide rail, and the third connecting block is vertically connected to the top surface of the pressure plate. The second connecting block and the third connecting block are parallel to each other, and a horizontal adjustment block is connected between the second connecting block and the third connecting block.

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.

[0019] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a conveying device for low-density polyethylene ampoules, such as... Figure 2 , Figure 3 As shown, the system includes a conveyor belt 1, guide rails 2, and guide pressure plates 3. The conveyor belt 1 is rotatably connected between two guard plates 12. Along the axial direction of the conveyor belt 1, each guard plate 12 is connected to a guide rail 2 through multiple guard rail connectors 5. Under the support of the guard rail connectors 5 and the guard plates 12, the bottom end of the guide rail 2 maintains a set distance from the top surface of the conveyor belt 1 (to avoid frictional interference between the conveyor belt 1 and the guide rail 2. In this embodiment, the bottom end of the guide rail 2 is kept one centimeter away from the top surface of the conveyor belt 1). The guide rails 2 installed on both sides of the conveyor belt 1 along its axial direction are used to guide the polyethylene ampoules 4 on the conveyor belt 1.

[0020] like Figure 2 , Figure 3 As shown, the guide plate 3 is installed between two guide rails 2. Specifically, the guide plate 3 is connected to the outside of one of the guide rails 2 through multiple plate connectors 6. The guide plate 3 flattens the rows of polyethylene ampoules 4 passing below, keeping them straight. When the rows of polyethylene ampoules 4 pass the guide plate 3, they cannot be rolled or stacked because the guide plate 3 is installed above them.

[0021] In this embodiment, the rear end of the conveyor belt 1 is connected to the dispensing track of the labeling machine. After being guided and smoothed by the conveyor belt 1, the polyethylene ampoules 4 enter the dispensing track of the labeling machine.

[0022] like Figure 2 , Figure 3 As shown, the guide plate 3 comprises two parts: a guide plate 31 and a pressure plate 32. The guide plate 31 is fixedly connected to one end of the pressure plate 32 at a set angle. Specifically, the guide plate 31 is fixedly connected to the end of the pressure plate 32 facing the polyethylene ampoule 4 at a set angle. When the curled polyethylene ampoule 4 passes the inclined guide plate 31, it is gradually smoothed out and gradually driven by the conveyor belt 1 through the pressure plate 32 to maintain a straight state until it enters the dispensing track of the labeling machine.

[0023] In this embodiment, both the guide plate 31 and the pressure plate 32 are made of steel plates, and the guide plate 31 and the pressure plate 32 can be fixedly connected together by welding at a set angle.

[0024] It should be noted that in this embodiment, the included angle between the guide plate 31 and the pressure plate 32 is an obtuse angle, and the obtuse angle needs to satisfy the range of 135°-160°, with the optimal value being 150°.

[0025] like Figure 2 As shown, the conveyor belt 1 also includes two drive shafts 11, which are rotatably connected to the guard plate 12, enabling the conveyor belt 1 to rotate relative to the guard plate 12. Driven by the drive shafts 11, the conveyor belt 1 performs the conveying function, used to convey the polyethylene ampoules 4. It is understood that the drive shafts 11 are connected to the output end of a motor, and the motor drives the drive shafts 11 to rotate. The conveyor belt is existing technology, and this embodiment does not modify the conveyor belt body; therefore, it will not be described in detail further.

[0026] like Figure 2As shown, the top of the guard plate 12 is flush with the top surface of the conveyor belt 1, and the bottom ends of the guard plates 12 are connected by a flat plate. The flat plate is connected to the top of the four support legs 13, and the bottom end of the support legs 13 is connected to an ear plate. Multiple bolt holes are opened on the ear plate, and bolts are used to connect the support legs 13 to the ground. The support legs 13 and the guard plate 12 provide support for the conveyor belt 1. In this embodiment, the guard plate 12, the flat plate, and the support legs 13 are made of steel, and the connection between the guard plate 12, the flat plate, and the support legs 13 is fixed by welding.

[0027] like Figure 2 , Figure 3 , Figure 4 As shown, the guardrail connector 5 is connected between the guard plate 12 and the guide guardrail 2. Specifically, the guardrail connector 5 includes a first connecting block 51. In this embodiment, the first connecting block 51 is an L-shaped block, including a horizontal block and a vertical block perpendicular to the horizontal block. The horizontal block of the first connecting block 51 is connected to the outside of the guard plate 12. The vertical block of the first connecting block 51 has a horizontal adjustment hole 52. An adjustment rod 53 is slidably connected in the adjustment hole 52. One end of the adjustment rod 53 is connected to the guide guardrail 2.

[0028] In this embodiment, the first connecting block 51 and the adjusting rod 53 are made of steel and are connected to the guide rail 2 by welding; the first connecting block 51 can also be made of aluminum alloy and can be connected to the guide rail 2 by opening bolt holes.

[0029] In this embodiment, two guardrail connectors 5 are provided between the guard plate 12 and the guide rail 2, which can support the guide rail 2. In actual production, the number of guardrail connectors 5 can be increased according to the length of the conveyor belt 1 to ensure the supporting effect on the guide rail 2.

[0030] In this embodiment, the adjusting rod 53 is slidably engaged with the first connecting block 51. By adjusting the corresponding positions of the adjusting rod 53 and the first connecting block 51, the corresponding position of the guide rail 2 can be adjusted. Figure 2 As shown, the distance between the two guide rails 2 can be adjusted by adjusting the positions of the guide rails 2 on both sides of the conveyor belt 1 along its axis. It is easy to understand that by adjusting the distance between the two guide rails 2 according to the length of the polyethylene ampoules 4 to be packaged, the guide rails 2 can guide the polyethylene ampoules 4 to be packaged.

[0031] In this embodiment, a vertical first threaded hole 54 is also provided at the top of the vertical block of the first connecting block 51. The first threaded hole 54 is connected to the adjustment hole 52. The first threaded hole 54 is internally threaded with a first locking bolt 55. When it is necessary to adjust the position of the guide rail 2 relative to the first connecting block 51, the first locking bolt 55 is loosened to allow the adjusting rod 53 to slide relative to the first connecting block 51. After the guide rail 2 is adjusted, the first locking bolt 55 is tightened so that the end of the first locking bolt 55 inside the first connecting block 51 presses against the adjusting rod 53, so that the adjusting rod 53 can no longer slide relative to the first connecting block 51.

[0032] It should be noted that the axis of the conveyor belt 1 is aligned with the track axis of the labeling machine. When the conveyor belt 1 transports the polyethylene ampoules 4, it ensures that the polyethylene ampoules 4 can enter the track of the labeling machine along the axial direction. Therefore, when adjusting the spacing of the guide rails 2 according to the specifications of the polyethylene ampoules 4 to be packaged, it is necessary to ensure that the spacing between the guide rails 2 and the axis of the conveyor belt 1 is consistent.

[0033] like Figure 2 , Figure 3 , Figure 5 As shown, the pressure plate connector 6 connects the guide rail 2 and the guide pressure plate 3. The pressure plate connector 6 includes a second connecting block 61 and a third connecting block 66. The second connecting block 61 is connected to the outside of the guide rail 2, and the third connecting block 66 is vertically connected to the top surface of the pressure plate 32. In this embodiment, both the second connecting block 61 and the third connecting block 66 are made of steel and are connected to the guide rail 2 or the pressure plate 32 by welding.

[0034] like Figure 2 , Figure 3 , Figure 5 As shown, the second connecting block 61 and the third connecting block 66 are in a parallel state, and a horizontal adjusting block 62 is connected between the second connecting block 61 and the third connecting block 66. Specifically, a vertical second threaded hole 63 is opened at the top of the second connecting block 61, and a horizontal adjusting groove 65 is opened on the horizontal adjusting block 62 (the horizontal adjusting groove 65 passes through the horizontal adjusting block 62 in the vertical direction). The second locking bolt 64 passes through the horizontal adjusting groove 65 and is threadedly connected to the second threaded hole 63, thereby connecting the top of the horizontal adjusting block 62 to the top of the second connecting block 61.

[0035] In this embodiment, the second threaded hole 63 is internally threaded to the second locking bolt 64. The diameter of the screw of the second locking bolt 64 is equal to the width of the horizontal adjustment groove 65. The diameter of the top screw of the second locking bolt 64 is greater than its screw diameter. When the second locking bolt 64 is tightened, the top screw of the second locking bolt 64 can press and lock the horizontal adjustment block 62 to the top of the second connecting block 61.

[0036] like Figure 2 , Figure 3 , Figure 5 As shown, the end of the horizontal adjusting block 62 facing the pressure plate 32 is connected to the third connecting block 66. A vertical adjusting groove 67 is provided on the third connecting block 66 (the vertical adjusting groove 67 passes through the third connecting block 66 in the direction towards the second connecting block 61). A third threaded hole 68 is provided on the end of the horizontal adjusting block 62 facing the pressure plate 32. A third locking bolt 69 passes through the vertical adjusting groove 67 and is threadedly connected to the third threaded hole 68, thereby connecting the horizontal adjusting block 62 and the third connecting block 66.

[0037] In this embodiment, the third threaded hole 68 is internally threaded to the third locking bolt 69. The diameter of the screw of the third locking bolt 69 is equal to the width of the vertical adjustment groove 67. The diameter of the top screw of the third locking bolt 69 is greater than the diameter of its screw. When the third locking bolt 69 is tightened, the top screw of the third locking bolt 69 can lock the horizontal adjustment block 62 to the top of the third connecting block 66.

[0038] In this embodiment, two pressure plate connectors 6 are provided between the pressure plate 32 and the guide rail 2, which can support the guide pressure plate 3. In actual production, the number of pressure plate connectors 6 can be increased according to the length of the guide pressure plate 3 to ensure the supporting effect on the guide pressure plate 3.

[0039] It should be noted that the axis of the conveyor belt 1 is aligned with the track axis of the labeling machine. When the conveyor belt 1 transports the polyethylene ampoules 4, it ensures that the ampoules 4 enter the track of the labeling machine axially. Therefore, when adjusting the spacing of the guide rails 2 according to the specifications of the polyethylene ampoules 4 to be packaged, it is necessary to ensure that the axial spacing between the guide rails 2 and the conveyor belt 1 is consistent. However, due to the different specifications of the polyethylene ampoules 4, the horizontal position of the guide plate 3 also needs to be changed. Simultaneously, the height of the guide plate 3 relative to the conveyor belt 1 needs to be adjusted according to the diameter of the polyethylene ampoules 4. Therefore, the horizontal position of the guide plate 3 can be changed by adjusting the horizontal position of the horizontal adjusting block 62 relative to the second connecting block 61, and the height of the guide plate 3 relative to the conveyor belt 1 can be changed by adjusting the vertical position of the horizontal adjusting block 62 relative to the third connecting block 66.

[0040] In this embodiment, when the second locking bolt and the third locking bolt are connected to the horizontal adjusting block, shims can be added to enhance the connection stability.

[0041] In this embodiment, a rubber pad is adhered to the opposite side of the guide rail 2 to prevent the polyethylene ampoule 4 from directly contacting the guide rail 2 during the conveying process and to avoid wear on the polyethylene ampoule 4.

[0042] In this embodiment, stiffening plates are fixedly connected to both sides of the top surface of the guide plate along the axial direction of the guide plate. The stiffening plates are perpendicular to the guide plate and are connected to the guide plate by welding.

[0043] 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.
