[0002] In the field of medicine production, a dust-free feeding station is a crucial device that focuses on reliable and sterile transfer of materials such as powder and granules. Its airtightness and efficient dust removal and filtration system not only effectively resist the invasion of external microorganisms, dust, and other pollutants, but also accurately intercept dust generated during the feeding process, creating a pure and sterile transfer environment for raw materials or intermediates. In dealing with cross-contamination, which is a critical and complex problem in the medicine production process, the dust-free feeding station builds a solid protective barrier with its independent feeding system, complete batch operation process, and dedicated cleaning program, making it an indispensable part of the medicine production process. It provides strong support for ensuring the high quality and safety of medicines, helping medicine production enterprises meet increasingly stringent regulatory requirements and produce higher quality and safer medicines.

[0013] (Three) beneficial effects Compared with the prior art, the present application provides a dust-free feeding station for medicine production, which has the following beneficial effects: The packaging bag fixing mechanism can insert the cone into the lower end surface of the packaging bag before feeding, so as to fix the packaging bag, avoid the blockage of material conveying caused by the packaging bag being stuck in the feeding port or pipeline, ensure the smooth feeding process, significantly improve the feeding efficiency, reduce the problems of material spilling or blockage caused by the shaking or displacement of the packaging bag, further ensure the stability of the feeding process, avoid the mixing of the packaging bag and the material or the sticking of the packaging bag in the corner inside the feeding station body, thereby reducing the time and effort spent on cleaning the packaging bag, reducing the risk of failure of the feeding station body caused by the residual packaging bag, and reducing the frequency and cost of maintenance of the feeding station body.

[0014] The vertical plate, the push rod, the push plate and the communication groove can simultaneously push the two sides of the packaging bag close to each other when the cone is inserted into the packaging bag, so that the material in the packaging bag flows out from the center of the bottom of the packaging bag. The concentrated flow of material from the center of the bottom of the packaging bag not only can complete the feeding process more quickly, reduce the residual time of the material in the packaging bag, thereby shorten the time required for each feeding, but also can make the material flow out more smoothly, reduce the need for manual intervention caused by material blockage or scattering, and the operator can focus more on other production tasks, thereby reducing the time and effort spent on cleaning or adjusting the feeding equipment.

[0015] By setting the feeding auxiliary mechanism, the cutting knife can be driven to rise synchronously during the process of driving the conical rising to insert into the bottom of the packaging bag, and the center of the bottom of the packaging bag is cut. Not only can a larger opening be quickly opened, so that the material can flow out of the packaging bag quickly and smoothly, reducing the residence time of the material in the packaging bag, improving the feeding speed and efficiency, but also the operation of cutting the packaging bag is synchronized with the feeding process, reducing the operation steps, improving the continuity and efficiency of the operation, making the feeding process more automated, and reducing the necessity of manual intervention. By setting the side plate, convex point, linkage rod and disc, the cutting knife can be driven to move horizontally and reciprocally synchronously during the process of cutting the center of the bottom of the packaging bag, which not only reduces the friction between the cutting knife and the packaging bag, makes the cutting process more smooth, reduces the cutting resistance, and improves the cutting efficiency, but also helps to reduce the excessive friction and jamming of the cutting knife with the fibers of the packaging bag during the cutting process, effectively avoids the cutting knife from being stuck due to fiber winding, and further improves the durability and reliability of the cutting knife.

[0016] By setting the sector gear, rack plate, slide column, linkage plate and moving plate, the two side flared rods can be driven to move horizontally away from each other during the process of cutting the center of the bottom of the packaging bag by the rising cutting knife, which enlarges the cutout of the cutting knife at the center of the bottom of the packaging bag. Not only can it more effectively promote the rapid flow of the material, reduce the residue of the material in the packaging bag, reduce the time required for each feeding, and significantly improve the feeding efficiency, but also the enlarged cutout can reduce the risk of blockage of the material in the feeding port, especially when dealing with materials with poor flowability, which can significantly improve the flowability of the material and avoid the poor feeding caused by material accumulation or dispersed flow.

[0024] In the prior art, due to some factors (the operator does not operate according to the correct method when disassembling the bag, or the operator is not concentrated or not skilled in operation during the feeding process), the packaging bag will fall into the dust-free feeding station together with the material, which not only causes the material to be unable to pass smoothly, blocks the feeding process, and reduces the feeding efficiency, but also causes the packaging bag to mix with the material or be stuck in the corner of the equipment, which is difficult to clean and requires a lot of time and effort to clean, increasing the maintenance cost and time of the equipment. Compared with the prior art, the conical body 602 is inserted into the lower end face of the packaging bag before feeding the packaging bag, which not only avoids the blockage of the material caused by the packaging bag being stuck in the feeding port or the pipeline, ensures the smooth feeding process, significantly improves the feeding efficiency, reduces the material spilling or blockage caused by the packaging bag shaking or shifting, further ensures the stability of the feeding process, and avoids the mixing of the packaging bag with the material or the packaging bag being stuck in the corner of the feeding station body 1, thereby reducing the time and effort consumed in cleaning the packaging bag, reducing the risk of failure of the feeding station body 1 caused by the packaging bag residue, and reducing the frequency and cost of maintenance of the feeding station body 1.

[0025] In other aspects, the present embodiment also provides a feeding assisting mechanism for assisting the feeding of the material in the packaging bag, as shown in Figure 4 、 Figure 6 - Figure 9 The feeding assisting mechanism includes a cutting knife 701 arranged on the upper end face of the lifting plate 609, the upper end face of the lifting plate 609 is provided with a sliding groove 703, the cutting knife 701 is slidingly connected in the sliding groove 703, the lifting columns 608 are fixedly connected to the lower end face of the cutting knife 701, and the upper end face of the lifting plate 609 is symmetrically provided with a material discharge groove 715 which is communicated with both ends of the sliding groove 703. When the material falls into the sliding groove 703 during feeding, the material in the sliding groove 703 is pushed into the material discharge groove 715 and discharged by the reciprocating movement of the cutting knife 701 in the sliding groove 703.

[0026] In the present embodiment, as shown in Figure 6 and Figure 7 , the upper end face of the lifting plate 609 is symmetrically provided with a first through groove 704, and the upper end face of the support plate 603 is provided with a second through groove 709, and the lifting columns 608 are respectively penetrated through the lifting plate 609 and the support plate 603 through the first through groove 704 and the second through groove 709. The first through groove 704 and the second through groove 709 not only enable the lifting columns 608 to slide up and down on the support plate 603 and the lifting plate 609, but also enable the lifting columns 608 to move horizontally on the support plate 603 and the lifting plate 609 during the up-and-down sliding.

[0027] In this embodiment, Figure 7 As shown, the lower end surfaces of the support plates 603 are symmetrically fixedly connected with side plates 705, and convex points 706 are equidistantly fixedly connected to the opposite sides of two adjacent side plates 705, and the convex points 706 on both sides are staggered with each other. A disc 708 is provided between the two adjacent side plates 705, and the discs 708 are fixedly connected to the lower ends of the lifting columns 608. The outer surfaces of the discs 708 are symmetrically fixedly connected with linkage rods 707, and the ends of the linkage rods 707 away from the discs 708 are on the same horizontal line as the convex points 706. When the lifting column 608 is rising, the linkage rods 707 will be driven to rise synchronously through the discs 708. At this time, the linkage rods 707 will be affected by the convex points 706 on both sides and will reciprocate left and right, thereby pushing the discs 708 to drive the lifting column 608 to move synchronously horizontally during the rising process.

[0028] In this embodiment, Figure 8 and Figure 9 As shown, the feeding auxiliary mechanism also includes a symmetrically arranged moving plate 710, the upper end surface of the moving plate 710 is equidistantly fixedly connected with the flaring rod 702, the lower end surface of the moving plate 710 is symmetrically fixedly connected with a linkage plate 711, the lower end of the linkage plate 711 is penetrated and fixedly connected with a sliding column 714, and the sliding column 714 is penetrated and slidably connected to the lifting plate 609. When the sliding column 714 slides out on the lifting plate 609, the linkage plate 711 is set, which can move the moving plate 710 to drive the flaring rod 702 to move synchronously, away from each other, and pull the two sides of the lower end surface of the packaging bag.

[0029] In this embodiment, Figure 9 As shown, the sliding column 714 is fixedly connected to the rack plate 712 at one end away from the lifting plate 609, and the upper end surface of the rack plate 712 is meshed with a sector gear 713, and the sector gear 713 is fixedly connected to the outer surface of the rotating shaft 613. When the rotating shaft 613 rotates and drives the sector gear 713 connected to the outer surface to rotate synchronously, the sector gear 713 and the rack plate 712 are meshed and connected, so that the sliding column 714 can be pushed to slide out of the lifting plate 609 or slide into the lifting plate 609 synchronously.

[0030] Compared with the prior art, the cutting blade 701 can be driven to rise synchronously while the driving cone 602 is being inserted into the bottom of the packaging bag, thereby cutting the center of the bottom of the packaging bag. This not only quickly opens a larger opening, allowing the material to flow out of the packaging bag quickly and smoothly, reducing the residence time of the material in the packaging bag and improving the feeding speed and efficiency, but also the operation of cutting the packaging bag is carried out simultaneously with the feeding process, reducing the number of operating steps, improving the consistency and efficiency of the operation, making the feeding process more automated, and reducing the need for manual intervention. The side plate 705, the convex point 706, the linkage rod 707 and the disc 708 are arranged, so that the cutting knife 701 can drive the packaging bag to move horizontally and reciprocatingly during the cutting process of the bottom center of the packaging bag, which can reduce the friction between the cutting knife 701 and the packaging bag, make the cutting process more smooth, reduce the cutting resistance, improve the cutting efficiency, and reduce the excessive friction and jamming of the cutting knife 701 with the packaging bag fibers during the cutting process, so that the cutting knife 701 can be effectively prevented from being stuck due to fiber winding, and the durability and reliability of the cutting knife 701 are further improved.

[0031] The working process and principles involved in the above embodiments are as follows: When the staff needs to put materials into the inside of the feeding station body 1, first, the packaging bag containing materials is placed on the supporting rod 5 in the inside of the feeding station body 1, then the driving motor 605 is turned on to drive the threaded rod 606 connected to the output end of the driving motor 605 to rotate, since the threaded rod 606 is screw-connected with the expansion plate 607, the expansion plate 607 is fixedly connected with the lifting column 608 at both ends, and the lifting column 608 is fixedly connected to the bottom of the cutting knife 701, so when the threaded rod 606 rotates, the expansion plate 607 can be driven to move vertically upward on the outer surface of the threaded rod 606 through the screw connection between the threaded rod 606 and the expansion plate 607, at the same time, the lifting column 608 at the upper end is pushed to move upward, the cutting knife 701 connected to the lifting column 608 is driven to move upward, and the bottom center of the packaging bag placed above the supporting rod 5 is cut, which can quickly open a larger opening, so that the materials can flow out of the packaging bag quickly and smoothly, the residence time of the materials in the packaging bag is reduced, the feeding speed and efficiency are improved, the cutting operation of the packaging bag is synchronized with the feeding process, the operation steps are reduced, the operation continuity and efficiency are improved, the feeding process is more automated, and the necessity of manual intervention is reduced. When the telescopic plate 607 pushes the cutting knife 701 to rise close to the bottom of the packaging bag through the lifting column 608 to cut the packaging bag, since the lower end of the lifting column 608 is fixedly connected to the disc 708, and the outer surface of the disc 708 is symmetrically fixedly connected to the linkage rod 707, and both sides of the linkage rod 707 are provided with convex points 706, and the convex points 706 on both sides are staggered with each other, as the lifting column 608 rises, the lifting column 608 is affected by the convex points 706 on both sides, which will push the linkage rod 707 to move back and forth, and drive the lifting column 608 to move synchronously through the disc 708, so that the lifting column 608 08 performs horizontal reciprocating movement synchronously during the ascending process, so that when the lifting column 608 pushes the cutting knife 701 close to the bottom center of the packaging bag, it can drive the cutting knife 701 to slide horizontally and reciprocatingly in the slide groove 703. This can not only reduce the friction between the cutting knife 701 and the packaging bag, making the cutting process smoother, reducing cutting resistance, and improving cutting efficiency, but also the horizontal reciprocating movement helps to reduce excessive friction and jamming between the cutting knife 701 and the packaging bag fibers during the cutting process, which can effectively prevent the cutting knife 701 from being stuck due to fiber entanglement, and further improve the durability and reliability of the cutting knife 701. During the rising process of the cutting knife 701, since the cutting knife 701 is slidably connected to the sliding groove 703 provided on the upper end surface of the lifting plate 609, the cutting knife 701 will drive the lifting plate 609 to rise synchronously under the influence of the sliding groove 703. At this time, since the lifting plate 609 is symmetrically fixedly connected to the fixed plates 612 on both sides, a rotating shaft 613 is provided between the fixed plates 612 on the same side, and the outer surface of the rotating shaft 613 is fixedly connected to the connecting plate 610, and the connecting plate 610 is fixedly connected to the supporting plate 601 on the side away from the rotating shaft 613, and the upper end surface of the supporting plate 601 is fixedly connected to the cone 602. Therefore, as the lifting plate 609 rises, the lifting plate 609 can drive the connecting plate 610 to move upward through the fixed plates 612 and the rotating shaft 613 connected on both sides. The connecting plate 610 rises synchronously, so that the connecting plate 610 pushes the cone 602 to be inserted into both sides of the lower end surface of the packaging bag through the supporting plate 601, thereby fixing the packaging bag. This not only avoids the obstruction of material transportation caused by the packaging bag being stuck in the feeding port or pipeline, but also ensures the smooth progress of the feeding process, significantly improves the feeding efficiency, reduces the problem of material spillage or blockage caused by shaking or shifting of the packaging bag, further ensures the stability of the feeding process, and avoids the situation where the packaging bag is mixed with the material or is stuck in the corner inside the feeding station body 1, thereby reducing the time and energy consumed in cleaning the packaging bag, reducing the risk of failure of the feeding station body 1 due to residual packaging bags, and reducing the frequency and cost of maintenance of the feeding station body 1; In the process that the lifting plate 609 rises to drive the cone 602 to be inserted into the lower end surface of the packaging bag, the lifting plate 609 drives the rotating shaft 613 to move upward synchronously through the fixed plate 612, away from the vertical plate 611 below. Since the two ends of the rotating shaft 613 are fixedly connected with the push plate 614, the push plate 614 is provided with the communication groove 615, and the push rod 616 is slidably connected in the communication groove 615, and the push rod 616 is fixedly connected to the vertical plate 611, therefore, in the process that the rotating shaft 613 rises away from the vertical plate 611 below, under the influence of the fixed position of the vertical plate 611 and the push rod 616, the end of the push plate 614 connected with the outer surface of the rotating shaft 613 will move from above the rotating shaft 613 to below the rotating shaft 613, at the same time, the push rod 616 will slide in the communication groove 615 of the push plate 614, and rotate the rotating shaft 613 through the push plate 614, and in the process of rotating the rotating shaft 613, the connecting plate 610 will rotate synchronously, and the supporting plate 601 connected with one side of the connecting plate 610 away from the rotating shaft 613 will rotate upward, at the same time, the two supporting plates 601 will drag the packaging bag on both sides to rotate upward and close to each other. At this time, the cutting knife 701 has already cut the center of the lower end surface of the packaging bag, so that when the two sides of the packaging bag are dragged to rotate upward and close to each other, the material in the packaging bag can flow out from the center of the bottom of the packaging bag. The material flowing out from the center of the bottom of the packaging bag can not only complete the feeding process more quickly, reduce the residual time of the material in the packaging bag, and shorten the time required for each feeding, but also can flow out more smoothly, reduce the need for manual intervention due to material blockage or scattering, and the operator can focus more on other production tasks, reduce the time and energy consumed for cleaning or adjusting the feeding equipment; When the rotating shaft 613 rotates the push plate 601 to drive the two sides of the packaging bag to rotate upward and close, the rotating shaft 613 will drive the symmetrical connection of the outer surface of the sector gear 713 to rotate synchronously, and when the sector gear 713 rotates, the sector gear 713 is meshed with the rack plate 712 below, the rack plate 712 is connected with the slide column 714 on the side close to the lifting plate 609, and the slide column 714 is slidingly connected to the lifting plate 609, so that the slide column 714 is driven to slide out of the lifting plate 609 synchronously by the meshing connection of the sector gear 713 and the rack plate 712. At this time, the slide column 714 will drive the moving plate 710 to move away from the lifting plate 609 synchronously through the linkage plate 711 connected to the outer surface, and the flared rod 702 connected to the upper end surface of the moving plate 710 will move synchronously during the movement of the moving plate 710. The flared rod 702 is arranged on both sides of the cutting knife 701, and the flared rod 702 will be inserted into the packaging bag synchronously with the rising of the cutting knife 701. Therefore, the flared rod 702 will drive the packaging bag to move to both sides during the movement, and since the packaging bag center is cut by the cutting knife 701 to form an opening, the flared rod 702 will drive the packaging bag to expand the opening cut below the packaging bag. Not only can it more effectively promote the rapid flow of materials, reduce the residue of materials in the packaging bag, reduce the time required for each feeding, significantly improve the feeding efficiency, but also the expanded cut can reduce the risk of blockage of materials in the feeding port, especially when processing materials with poor flowability, it can significantly improve the flowability of the materials, avoid the poor feeding caused by the accumulation or dispersion of the materials.
