Description

Technical Field

[0001] This utility model relates to the field of transport trolley technology, specifically to a transfer trolley for disposable sterile multilayer co-extruded bags. Background Technology

[0002] There are 17 types of disposable sterile multilayer co-extruded bags used in the rabies vaccine raw material production workshop, with a maximum single transfer quantity of over 60 bags. When needed, they must be transferred from the rabies vaccine workshop logistics channel through the general area corridor to the workshop's small storage rack for temporary storage, and then transferred to various areas of the production workshop when needed. Since the disposable sterile multilayer co-extruded bags are made of plastic film, using conventional trolleys for transportation can lead to collisions, squeezing, and drops during transfer and storage, resulting in damage, tearing, or deformation. It is impossible to carry out targeted transportation of disposable sterile multilayer co-extruded bags. Although it is possible to transport disposable sterile multilayer co-extruded bags, the following drawbacks still exist. First, there are 17 types of disposable sterile multilayer co-extruded bags used in production. During transportation, these bags are stacked together, which can easily cause confusion and make it difficult to adapt to the complex classification specifications and meet storage requirements. Second, if a small number of disposable sterile multilayer co-extruded bags are transported at a time, there will still be gaps between the bags and the storage compartment of the trolley, making stable transportation impossible. During the transfer process, the bags are prone to collision, compression, and falling due to bumps. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] like Figure 1 - Figure 8 As shown, this embodiment proposes a transfer cart for disposable sterile multilayer co-extruded bags, including a cart body with rollers 7 connected to the bottom of the cart body. The cart body includes a first box 1 and a second box 2, with the back of the first box 1 connected to the front of the second box 2. The first box 1 has a storage space inside, and the storage space is provided with several spaced partitions 4. The partitions 4 are connected to the box wall, and adjacent partitions 4 divide the storage space into several compartments 3. The front of the first box 1 is an open end. The second box 2 also has a storage space inside, and the storage space is also provided with partitions 4. The partitions 4 divide the storage space into storage slots 8. The back of the second box 2 is an open end. In some embodiments, the first box 1 and the second box 2 are fixedly connected by welding and adopt a stainless steel flat structure. The edges and welding surfaces are polished to ensure the stability of the connection and prevent the transfer vehicle body from damaging the disposable sterile multilayer co-extruded bag. The partition 4 is also connected to the box walls of the first box 1 and the second box 2 by welding to ensure the structural stability of the compartment 3 and the storage tank 8. The partition forms different compartments according to the size of the disposable sterile multilayer co-extruded bag, which can effectively separate different types of disposable sterile multilayer co-extruded bags. In some embodiments, both the first box 1 and the second box 2 are provided with a protective edge 5 on the top, with the first box 1 being higher than the second box 2. The protective edge 5 is formed because the top plate of the box is lower than the surrounding box wall edge during welding, which allows other items to be placed during transportation and prevents them from falling. The edges of the protective edge 5 are rounded to prevent scratching the transportation personnel. The design of the first box 1 being higher than the second box 2 forms a stepped structure, which allows both to adapt to the storage needs of co-extruded bags of different heights during use, improving space utilization. Handles 6 are provided on both the front and back of the vehicle body, making it easier for the vehicle body to move in different directions during movement.

[0028] In some embodiments, the open end of the second housing 2 is connected to the cabinet door 9, and the cabinet door 9 is connected to the second housing via a hinge; the cabinet door 9 can meet the requirements of dust prevention and higher environmental cleanliness in the purification area of ​​the vehicle body, while preventing the co-extruded bag from falling off the open end during transportation. In some embodiments, a baffle 14 is connected to the bottom of the opening end of the second housing 2, and a hinge is connected between the baffle 14 and the second housing, allowing the baffle 14 to open and close. The second housing 2 and the baffle 14 are respectively provided with snap-fit ​​components for positioning the baffle 14. When the baffle 14 is closed, it supports the co-extruded bag at the bottom of the second housing 2, preventing the disposable sterile multilayer co-extruded bag from slipping off the bottom. The baffle 14 is more suitable for the requirements of frequent access in the cell area. The snap-fit ​​components include slots on both sides of the second housing 2 and blocks on both sides of the baffle 14. When the baffle 14 is closed, the blocks engage with the slots to position the baffle 14. When the baffle 14 needs to be opened, the blocks are simply removed from the slots. In some embodiments, the rollers 7 are brakeable casters. The brakeable casters allow the transfer cart to move flexibly, facilitating the transfer of disposable sterile multilayer co-extruded bags between different areas within the workshop; when storing disposable sterile multilayer co-extruded bags, the rollers 7 can be locked by a braking device to prevent the transfer cart from moving on its own. In some embodiments, at least one compartment 3 is detachably connected to a telescopic fixing frame, which includes a telescopic support, side plates 11 connected to both sides of the telescopic support, and at least one baffle 14 detachably connected to the middle section of the telescopic support. The telescopic fixing frame can be adjusted according to the size and quantity of the co-extruded bags, thereby improving the utilization rate of the space in the compartment 3 and providing better fixation for the co-extruded bags to prevent shaking and collision during transportation. In some embodiments, the telescopic support is composed of several X units, with the ends of adjacent X units hinged together by a pin. Each X unit includes a first support rod 12 and a second support rod 13. The middle sections of the first support rod 12 and the second support rod 13 are hinged together by a pin to form the X unit. One end of the first support rod 12 is rotatably connected to the side plate 11, and one end of the second support rod 13 is slidably connected to the side plate 11. This telescopic support structure composed of X units is simple and can be flexibly extended and retracted. The length of the telescopic support can be changed by adjusting the opening and closing degree of the X units, thereby adapting to disposable sterile multilayer co-extruded bags of different lengths. In some embodiments, the telescopic fixing frame is provided with a locking mechanism, which includes a guide tube 16, a guide rod 17, and a slide rail 18. A plurality of guide tubes 16 are fixedly connected to the outer wall of the side plate 11 at intervals. The guide tubes 16 can be square, round, etc. The shape of the guide rod 17 is adapted to the guide tube 16. By inserting the guide rod 17 into different guide tubes 16, the slide rail 18 can be connected laterally or obliquely, which can better adapt to different sizes of compartments 4. One end of the guide rod 17 is connected to a threaded rod 25, and a protrusion 2 is provided at the connection between the guide rod 17 and the threaded rod 25. 4. The slide rail 18 has a slide groove 26, and the threaded rod 25 is inserted into the slide groove 26. The threaded rod 25 can slide in the slide groove 26. The threaded rod 25 is threadedly connected to the hand-tightening nut 19. The other end of the guide rod 17 is inserted into the guide tube 16. When the telescopic bracket is adjusted to a suitable length, the guide rod 17 and the slide rail 18 are fixed by tightening the hand-tightening nut 19 through the cooperation of the protrusion 24 and the hand-tightening nut 19. This causes the guide rod 17 to be fixed in the guide tube 16, thereby locking the telescopic bracket and preventing the telescopic bracket from extending or retracting on its own during transportation.

[0029] In some embodiments, the baffle 14 includes a first vertical plate 22, and a second vertical plate 23 is connected to the side of the first vertical plate 22. A notch 15 is formed in the middle section of the side of the first vertical plate 22. A through hole and a slot 27 are formed in the middle section of the front of the second vertical plate 23. The through hole is located above the slot 27. A central hole is provided in the pin shaft. The through hole and one of the central holes are connected by a first fastener 20. This central hole is the upper central hole of the X unit. The first fastener 20 is rotatably connected to the through hole. The slot 27 is connected to the other central hole by a second fastener 21. This central hole is the lower central hole of the X unit. The second fastener 21 is slidably connected to the slot 27. This structural design of the baffle 14 allows it to be disassembled. An appropriate number can be installed according to the width of the disposable aseptic multilayer co-extruded bag. By sliding the position of the second fastener 21 in the slot 27, the first fastener 20 is rotated, thereby changing the distance between the baffles 14 to accommodate disposable aseptic multilayer co-extruded bags of different widths. Both the first fastener 20 and the second fastener 21 are bolted and nut-fitted to ensure the stability of the connection. In some embodiments, both the side panel 11 and the baffle 14 are covered with anti-scratch strips. The anti-scratch strips are made of silicone and are glued to the surface of the side panel 11 and the baffle 14. They can effectively prevent the disposable sterile multilayer co-extruded bags from being scratched by the side panel 11 and the baffle 14 during placement and transportation, thus protecting the co-extruded bags.

[0030] Working principle: When using, first determine the number of baffles 14 to be assembled according to the specifications of the disposable sterile multi-layer co-extruded bag. Assemble the required baffles 14 on the telescopic bracket. The locking mechanism is inserted into the side plate 11 according to the usage compartment. Place the fixed telescopic frame into the compartment 3, put the disposable sterile multi-layer co-extruded bag into the fixed telescopic frame, push one side plate 11 to clamp the telescopic fixed frame, turn the hand-tightening nut 19 to position the locking mechanism, and then lock the telescopic fixed frame, avoiding the problem of the telescopic fixed frame loosening due to bumps during transportation. In summary, this utility model is convenient for transportation and storage, has a stable structure, and is easy to operate. It can be quickly installed or disassembled without complicated tools, preventing the problems of complicated and confusing processes during transportation. At the same time, the disposable sterile multi-layer co-extruded bag can ensure stable transportation during movement, reducing the damage rate of the product.
