Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an automatic unpacking and feeding equipment for the production of non-sterile raw materials. Background Technology

[0002] In the production of non-sterile active pharmaceutical ingredients (APIs), raw material feeding is a crucial initial step. Currently, common feeding methods are mainly divided into manual feeding and semi-automatic feeding. Manual feeding relies entirely on operators using tools to manually unpack and pour the materials, which is the basic method used by most small and medium-sized pharmaceutical companies. Some modern factories use semi-automatic feeding equipment, such as simple feeding stations with fixed cutting devices, or unpacking machines that require manual positioning. These devices reduce labor intensity to some extent and are currently the main form of feeding technology.

[0003] However, existing manual or semi-automatic feeding methods still have significant shortcomings: manual operation is prone to spillage due to uneven force or operational errors, resulting in raw material waste and the risk of cross-contamination; while semi-automatic equipment can partially reduce labor intensity, it still lacks in positioning accuracy and the continuity of actions, such as misalignment of packaging bags, cutting positions, and removal of remaining empty bags, affecting overall feeding efficiency and drug production quality. Therefore, there is an urgent need for an automated unpacking and feeding device that can achieve precise positioning, automatic cutting, continuous operation, and effective material collection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic unpacking and feeding device for the production of non-sterile raw materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic unpacking and feeding device for non-sterile active pharmaceutical ingredients (APIs) production includes a base. The top of the base has a feeding trough, a first chute, and a second chute. The feeding trough is located between the first and second chutes. A cutting mechanism is installed within the feeding trough. Movable seats are slidably installed within both the first and second chutes. A threaded rod, threadedly connected to the movable seat, is rotatably connected within the first chute. A motor driving the threaded rod is fixedly connected to one side of the base. A sliding rod, slidably sleeved with the movable seat, is fixedly connected within the second chute. A common support frame is fixedly connected to the top of both movable seats. An electric push rod is fixedly connected to the top of the support frame. The telescopic end of the electric push rod passes through the support frame and is fixedly connected to a lower pressure plate. Pressure blocks are fixedly connected to both sides of the bottom of the lower pressure plate.

[0006] As a further improvement of this utility model, the cutting mechanism includes fixed columns fixedly connected to the inner walls on both sides of the feeding trough, and a cutting blade is fixedly sleeved on the fixed columns.

[0007] As a further improvement of this utility model, a guide frame is fixedly connected to the top of the base near the support frame, and a lower pocket groove is opened on the top of the base away from the guide frame.

[0008] As a further improvement of this utility model, each of the four corners of the bottom of the base is fixedly connected with a support column, and a guide hopper is fixedly connected to the bottom of the base, with the feed inlet of the guide hopper facing the discharge trough.

[0009] As a further improvement of this utility model, a baffle is fixedly connected to one side of each of the two movable seats, and the baffle is located on the side of the support frame away from the guide frame.

[0010] As a further improvement of this utility model, the first slide groove and the second slide groove have the same length and internal size.

[0011] The beneficial effects of this utility model are: The threaded rod and slide bar driven by the motor work together to guide the two moving seats, ensuring that the support frame and pressing mechanism move synchronously and smoothly. This allows the pressed raw material bags to be cut precisely and at a uniform speed by the cutting blade. Combined with the local pressing design of the lower pressure plate and pressing block, the packaging bags are effectively fixed while avoiding the entire bag being pressed down and affecting the material falling. This achieves automation, accurate positioning, and smooth operation of the unpacking and feeding process, improving production efficiency and reducing manual intervention and material spillage.

[0012] This invention enables automatic positioning, precise packaging, material collection, and empty bag discharge of raw material bags, effectively improving the automation level of non-sterile raw material feeding. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-4 An automatic unpacking and feeding device for non-sterile raw material production includes a base 1. The top of the base 1 has a feeding trough 5, a first chute 2, and a second chute 3. The first chute 2 and the second chute 3 have the same length and internal size, providing symmetrical guide tracks for moving parts. The feeding trough 5 is located between the first chute 2 and the second chute 3, serving as the main channel for material discharge. Support columns 8 are fixedly connected to the four corners of the bottom of the base 1 to support the entire device and maintain stability. A guide hopper 7 is fixedly connected to the bottom of the base 1. The inlet of the guide hopper 7 faces the feeding trough 5 to collect and concentrate the falling material. A cutting mechanism is provided inside the feeding trough 5. The cutting mechanism includes fixed columns 17 fixedly connected to the inner walls on both sides of the feeding trough 5. A cutting blade 6, which is a ring blade, is fixedly sleeved on the fixed column 17 to cut the raw material packaging bag when the material packaging moves.

[0017] Both the first slide groove 2 and the second slide groove 3 are equipped with movable seats 9. The first slide groove 2 is rotatably connected to a threaded rod 19 that is threaded to the movable seat 9, converting the rotational motion into linear drive. A motor 15 that drives the threaded rod 19 to rotate is fixedly connected to one side of the base 1, providing power for movement. The second slide groove 3 is fixedly connected to a slide rod 18 that is slidably sleeved with the movable seat 9, which works in conjunction with the threaded rod 19 to ensure that the two movable seats 9 move synchronously and smoothly. The tops of the two movable seats 9 are fixedly connected to the same support frame 11, forming a gantry frame that can move laterally. The top of the support frame 11 is fixedly connected to an electric push rod 12. The telescopic end of the electric push rod 12 passes through the support frame 11 and is fixedly connected to a lower pressure plate 13, providing vertical clamping force. Pressure blocks 16 are fixedly connected to both sides of the bottom of the lower pressure plate 13, which are used to provide local pressure when pressing the packaging bag.

[0018] A guide frame 14 is fixedly connected to the top of the base 1 near the support frame 11. The guide frame 14 is an inclined frame, which allows the raw material bag to move under its own weight to the bottom of the two pressure blocks 16. This is used to position the raw material bag at the initial work position. A lower bag groove 4 is provided on the top of the base 1 away from the guide frame 14, which provides a discharge channel for the empty bag after unpacking. A baffle 10 is fixedly connected to one side of the two movable seats 9. The baffle 10 is located on the side of the support frame 11 away from the guide frame 14. This is used to block the moving raw material bag and make its position accurately move to the bottom of the two pressure blocks 16.

[0019] In use, the operator first places the aligned raw material bag inside the guide frame 14. Because the guide frame 14 is slanted, the raw material bag automatically slides and moves under its own weight until it is blocked by the baffle 10, thus confining it to the initial position directly below the two pressure blocks 16. Then, the electric push rod 12 is activated, driving the lower pressure plate 13 and the pressure block 16 fixed to its bottom downwards, pressing the sealed edges of the raw material bag firmly onto the table surface of the moving seat 9. At this time, the motor 15 is activated, driving the threaded rod 19 to rotate. Since one moving seat 9 is threadedly connected to the threaded rod 19, and the other moving seat 9 is slidably connected to the slide rod 18, and the support frame 11 connects the two moving seats 9, the two moving seats 9 can move synchronously and smoothly under the threaded drive and the guidance of the slide rod 18, thereby driving the entire support frame 11 and its lower pressure plate 13, pressure block 16, and baffle 10 to move laterally together. The compressed raw material bag is then dragged along, and when its bottom passes the cutting blade 6 above the feeding trough 5, the sharp annular cutting blade 6 cuts through the packaging bag. Under the action of gravity, the material falls through the feeding trough 5 into the guide hopper 7 below, and is finally collected and discharged to the next process. After unpacking, the support frame 11 continues to move above the lower bag trough 4, and then drives the electric push rod 12 to release the two pressure blocks 16. The empty bag loses pressure support and falls into the lower bag trough 4 under its own gravity, and is discharged through the lower bag trough 4.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
