Description

Technical Field

[0001] This utility model relates to the field of powder filling and spreading technology, specifically a powder spreading machine for wet heat sterilization. Background Technology

[0002] In the production of pharmaceutical powders, moist heat sterilization is a crucial step to ensure that the microbial content of the powder meets quality standards. Currently, after processing by a pulverizer, the powder needs to be temporarily stored in large white drums. Then, operators use stainless steel ladles to manually scoop the powder into sterilization trays, leveling it by hand before it enters the moist heat sterilization device. However, this traditional manual tray-spreading method has significant technical defects and shortcomings:

[0003] First, manual tray spreading is inefficient, severely restricting the overall capacity of the production line and resulting in wasted labor costs. Second, the spillage of powder during manual tray spreading is unavoidable, increasing production costs and affecting the cleanliness of the production environment, which is detrimental to overall workshop management and drug quality control. In addition, the pulverized powder needs to be temporarily stored in large white buckets, which not only increases the workshop's storage space requirements but may also further affect the layout and efficiency of the production line due to limitations in upstream processes such as factory design.

[0004] Therefore, there is an urgent need for equipment that can automate, efficiently and accurately complete the powder spreading process, in order to overcome the shortcomings of existing technologies and improve the overall efficiency and quality of powder production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a tray spreading machine for wet heat sterilization of pharmaceutical powder.

[0006] The technical solution of this utility model is:

[0007] A tray-laying machine for wet heat sterilization of pharmaceutical powder includes a frame, on which a sterilization tray placement device, a sterilization tray conveying device, and a tray-laying device are mounted. The tray-laying device comprises a lifting assembly and a pharmaceutical powder hopper. Two partitions are slidably installed from top to bottom within the pharmaceutical powder hopper, dividing it into a pharmaceutical powder storage hopper, a pharmaceutical powder buffer hopper, and a pharmaceutical powder dispensing hopper. A weight detection switch is installed on the partition between the pharmaceutical powder buffer hopper and the pharmaceutical powder dispensing hopper. A support frame is fixed to the outside of the pharmaceutical powder hopper at corresponding positions on the partitions. Slide grooves are formed inside the support frame and within the pharmaceutical powder hopper. Slide rails corresponding to the slide grooves are installed on both sides of the partitions. A sliding rod is fixed to the support frame. A connecting block is present on the partition, and the connecting block is movably connected to the sliding rod. A push-pull cylinder is fixed to the outside of the pharmaceutical powder hopper, and the piston rod of the push-pull cylinder is connected to the connecting block. The lifting assembly includes a lifting cylinder and a lifting tray.

[0008] Furthermore, the lifting cylinder is fixed to the frame by a fixing bracket, and the lifting cylinder is fixed below the lifting plate. The lifting plate is an L-shaped plate, and a plate-laying detection switch is installed below the lifting plate.

[0009] Furthermore, the powder container is fixed above the lifting assembly by a support frame I, and the support frame I is bolted to the frame.

[0010] Furthermore, the sterilization tray conveying device includes drive shafts installed at both ends of the frame, the drive shafts being driven by a motor, and conveyor belts being fitted onto both ends of the drive shafts. Several conveyor rods are evenly connected between the conveyor belts, and several conveyor blocks are evenly installed on the conveyor rods. Anti-slip blocks are fixed on the conveyor blocks. A sterilization tray detection switch I is provided at the corresponding position between the frame and the end of the conveyor belt.

[0011] Furthermore, the sterilization tray placement device includes a support frame II, two transmission components, and two transport components. The support frame II is bolted to the machine frame, and a motor is mounted on the support frame II. The transmission components include two transmission gears, with a transmission chain between the transmission gears. The transport components include two transport gears, with a transport chain between the transport gears. One transmission gear of the transmission component I is driven by a motor, and the other transmission gear of the transmission component I is connected to the transport gear of the transport component I. The other transport gear of the transport component I is connected to the transmission gear of the transmission component II, and the transmission gear of the transmission component II meshes with the transport gear of the transport component II. A sterilization tray detection switch II is provided at the position corresponding to the transport component I on the support frame II.

[0012] Furthermore, the transmission gear and the transport gear are double gears.

[0013] Furthermore, the transport chain is composed of multiple links that are hinged together, and each link has a fixing plate on its chain plate, the fixing plate being an L-shaped plate.

[0014] Furthermore, both the transmission chain and the transport chain are provided with protective shells.

[0015] Furthermore, the bottom of the frame, support frame I, and support frame II are all equipped with casters.

[0016] The beneficial effects of this utility model are:

[0017] The powder pulverized by the pulverizer can be directly transported to the powder silo via a pipeline conveying system. The sterilization tray placement device automatically lowers the sterilization tray onto the sterilization tray conveying device, which then precisely delivers the tray to the corresponding position on the filling and spreading device. The filling and spreading device completes the automatic filling and spreading of the powder. After filling and spreading, the sterilization tray is conveyed to the end of the conveyor belt via the sterilization tray conveying device. Workers only need to assist in transferring the tray to the moist heat sterilization device. The entire process achieves closed transmission and precise operation through automated connection, avoiding temporary storage of powder and manual scooping, significantly reducing powder spillage and loss and the risk of microbial contamination. At the same time, it improves the uniformity of filling and spreading efficiency, reduces labor costs and labor intensity, and meets the needs of large-scale production. Attached Figure Description

Detailed Implementation

[0027] 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 are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figures 1 to 3 As shown, a powder moist heat sterilization tray spreading machine includes a frame 1, on which a sterilization tray placement device 2, a sterilization tray conveying device 6, and a material loading and spreading device 3 are mounted. The material loading and spreading device 3 includes a lifting assembly and a powder hopper 3-1. Two partitions 3-2 are slidably installed from top to bottom inside the powder hopper 3-1, dividing it into a powder storage hopper 3-3, a powder buffer hopper 3-4, and a powder discharging hopper 3-5. A weight detection switch 3-10 is installed on the partition 3-2 between the powder buffer hopper 3-4 and the powder discharging hopper 3-5. A support frame 3-6 is fixed at the corresponding position on the external partition 3-1. A sliding groove 3-9 is provided inside the support frame 3-6 and the powder hopper 3-1. Slide rails corresponding to the sliding groove 3-9 are installed on both sides of the partition 3-2 (not shown in the figure, the rest are the same). A sliding rod 3-7 is fixed on the support frame 3-6. A connecting block 3-8 is provided on the partition 3-2. The connecting block 3-8 is movably connected to the sliding rod 3-7. A push-pull cylinder 3-14 is fixed outside the powder hopper 3-1. The piston rod of the push-pull cylinder 3-14 is connected to the connecting block 3-8. The lifting assembly includes a lifting cylinder 3-11 and a lifting plate 3-13.

[0029] Automatic powder loading and spreading is achieved through the sterilization tray placement device 2, the sterilization tray conveying device 6, and the powder loading and spreading device 3. The powder hopper 3-1 is divided into a powder storage hopper 3-3, a powder buffer hopper 3-4, and a powder discharge hopper 3-5 by two sliding partitions 3-2. The partitions 3-2 are linked by slide rails, chutes 3-9, and push-pull cylinders 3-14 to ensure that the powder falls quantitatively in a sealed environment. A weight detection switch 3-10 can monitor the powder buffer hopper 3-4 in real time. Regarding the state of the Chinese medicine powder, when the powder in the powder buffer bin 3-4 reaches the specified weight, the weight detection switch 3-10 transmits a signal to the push-pull cylinder 3-14, which drives the partition 3-2 separating the powder storage bin 3-3 and the powder buffer bin 3-4 to pull back and close, stopping the powder storage bin 3-3 from discharging, thus avoiding overfilling or underfilling; the lifting component drives the lifting plate 3-13 through the lifting cylinder 3-11, so that the sterilization plate 11 remains stably aligned during the filling process, ensuring that the powder is evenly spread.

[0030] In a preferred embodiment of this utility model, the lifting cylinder 3-11 is fixed to the frame 1 by the fixing bracket 3-12. The lifting cylinder 3-11 is fixed below the lifting plate 3-13, which is an L-shaped plate. A tray-laying detection switch 8 is set below the lifting plate 3-13. The lifting plate 3-13 is driven by the cylinder to lift and lower, which is simple in structure and easy to maintain. The L-shaped plate of the lifting plate 3-13 can support the sterilization tray 11 and prevent the sterilization tray 11 from shifting during the lifting process. The tray-laying detection switch 8 is set below the lifting plate 8. When the sterilization tray 11 reaches the corresponding position of the lifting plate 3-13, it transmits a signal to the lifting cylinder 3-11 to drive the lifting plate 3-13 to rise. When the lifting plate 3-13 rises to the designated position, it transmits a signal to the push-pull cylinder 3-14, and the powder feeding hopper 3-5 opens. The loading and tray-laying work is carried out through linkage control, which provides a precise process connection guarantee for continuous production.

[0031] In a preferred embodiment of this utility model, the powder hopper 3-1 is fixed above the lifting assembly by a support frame I5, and the support frame I5 is bolted to the frame 1.

[0032] like Figures 4 to 5 As shown, the sterilization tray conveying device 6 includes a drive shaft 6-1 set at both ends of the frame 1. The drive shaft 6-1 is driven by a motor 12. The two ends of the drive shaft 6-1 are fitted with a conveyor belt 6-3. Several conveyor rods 6-2 are evenly connected between the conveyor belts 6-3. Several conveyor blocks 6-4 are evenly set on the conveyor rods 6-2. Anti-slip blocks 6-5 are fixed on the conveyor blocks 6-4. A sterilization tray detection switch I9 is ​​provided at the corresponding position of the end of the frame 1 and the end of the conveyor belt 6-3.

[0033] The drive shaft 6-1 and the transmission belt 6-3 driven by the motor 12 form a closed-loop conveying system. The uniformly distributed transmission rods 6-2, transmission blocks 6-4 and anti-slip blocks 6-5 ensure that the sterilization trays 11 maintain stable contact and anti-slip displacement during the conveying process. At the end, the tray detection switch I9 detects that there are sterilization trays 11 at the end of the transmission belt 6-3 and sends a signal, and the transmission belt 6-3 stops running to avoid the sterilization trays 11 from stacking and colliding.

[0034] like Figures 6 to 8 As shown, the sterilization tray placement device 2 includes a support frame II4, two transmission components, and two transport components. The support frame II4 is bolted to the frame 1. A motor 12 is mounted on the support frame II4. The transmission components include two transmission gears, with a transmission chain 2-6 between them. The transport components include two transport gears, with a transport chain 2-5 between them. One transmission gear 2-11 of transmission component I2-1 is driven by the motor 12, and the other transmission gear 2-11 of transmission component I2-1 is connected to the transport gear 2-21 of transport component I2-2. The other transport gear 2-21 of transport component I2-2 is connected to the transmission gear II2-31 of transmission component II2-3. The transmission gear III2-32 of transmission component II2-3 meshes with the transport gear II2-41 of transport component II2-4. A sterilization tray detection switch II10 is provided at the position corresponding to the transport component I2-2 on the support frame II4.

[0035] In a preferred embodiment of this utility model, the transmission gear Ⅲ2-32 and the transport gear Ⅱ2-41 are double gears.

[0036] The transmission and transport components are linked by a gear chain. Motor 12 drives the transmission chain 2-5 through multi-stage gear meshing, ensuring smooth operation and uniform lowering of the sterilization tray 11. Sterilization tray detection switch II 10 monitors the position of the sterilization tray 11 on the transport chain 2-5 in real time. Combined with precise control of the transmission and transport gears, it ensures the sterilization tray 11 stops accurately at the designated position. The transmission gear III 2-32 and transport gear II 2-41 are double gears. The first layer of teeth of transmission gear III 2-32... The wheel and transmission gear II2-31 are driven by a chain. The second gear of transmission gear III2-32 meshes with the first gear of transport gear II2-41 to achieve the transmission function. The second gear of transport gear II2-41 is connected to transport gear III2-42 through transport chain 2-5. The sterilization tray placement device 2 and the sterilization tray detection switch II10 work together to control the automatic lowering and start / stop of the sterilization tray 11, which improves the positioning accuracy of the sterilization tray and effectively prevents the risk of empty operation or tray stacking.

[0037] In a preferred embodiment of this utility model, the transport chain 2-5 is composed of multiple chain links 2-51, which are hinged together. Each chain link 2-51 has a fixing plate 2-53 on its chain plate 2-52, and the fixing plate 2-53 is an L-shaped plate. In this way, while maintaining the transmission of the transport chain 2-5, the load-bearing stability between the chain links 2-51 can be enhanced, ensuring the reliable fixation of the sterilization tray 11 during the vertical lowering process.

[0038] As a preferred embodiment of this utility model, both the transmission chain 2-6 and the transport chain 2-5 are provided with protective shells (not shown in the figure, the same applies to the rest); the protective shells on the outside of the chains can prevent dust from adhering to the chains during operation and causing the chains to jam.

[0039] In a preferred embodiment of this utility model, the bottom of the frame 1, support frame I 5, and support frame II 4 are all provided with casters 7; the casters 7 can move the equipment flexibly to a position that is convenient for working.

[0040] The working sequence of this utility model is as follows: The operator places the sterilization trays 11 sequentially onto the sterilization tray placement device 2, activates the device 2, and the sterilization trays 11 sequentially fall onto the sterilization tray conveying device 6. This triggers the sterilization tray detection switch II 10, and the conveying device 6 begins operation. The sterilization trays 11 are then conveyed to the corresponding position on the loading and spreading device 3. At this time, the spreading detection switch 8 is triggered, and the lifting assembly begins operation. The lifting cylinder 3-11 drives the sterilization trays 11 on the lifting plate 3-13 to rise to the opening of the powder feeding hopper 3-5. Driven by the push-pull cylinder 3-14, the powder is released from the powder buffer hopper 3-5. -4 The powder is fed into the sterilization tray 11 along the powder feeding bin 3-5. After the powder is filled, the sterilization tray 11 descends. The weight detection switch 3-10 detects that the powder in the powder buffer bin 3-4 is empty and sends a signal to the push-pull cylinder 3-14. The push-pull cylinder 3-14 drives the powder buffer bin 3-4 to perform the next powder filling operation. After the sterilization tray 11 descends to the designated position, the sterilization tray conveying device 6 continues to convey the powder-filled sterilization tray 11 to the end of the sterilization tray conveying device 6. At this time, the staff will transfer the sterilization tray 11 to the powder moist heat sterilization device for the next step of powder moist heat sterilization.

[0041] The above description is merely a preferred embodiment of this utility model. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, are all covered within the protection scope of this utility model.
