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.

[0017] (Three) beneficial effects

[0018] Compared with the prior art, the present application provides a dust-free feeding station for medicine production, which has the following beneficial effects:

[0019] 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 situation that the packaging bag is stuck in the corner inside the feeding station body, thereby reducing the time and effort consumed for 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.

[0020] 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 centralized 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 shortening 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 enable the operator to focus more on other production tasks, thereby reducing the time and effort consumed for cleaning or adjusting the feeding equipment.

[0021] 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, reducing the necessity of manual intervention.

[0022] Wherein, 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 rising and cutting the center of the bottom of the packaging bag. Not only can the friction between the cutting knife and the packaging bag be reduced, making the cutting process more smooth, reducing the cutting resistance and improving the cutting efficiency, but also the horizontal reciprocating movement helps to reduce the excessive friction and jamming of the cutting knife with the fibers of the packaging bag during the cutting process, which can effectively prevent the cutting knife from being stuck due to fiber winding, further improving the durability and reliability of the cutting knife.

[0023] 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, expanding 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 material, reduce the residue of material in the packaging bag, reduce the time required for each feeding, and significantly improve the feeding efficiency, but also the expanded cutout can reduce the risk of blockage of the material in the feeding port. Especially when dealing with materials with poor flowability, the flowability of the material can be significantly improved, avoiding the poor feeding caused by material accumulation or dispersed flow.

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.

[0043] 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 pass through the lifting plate 609 and the support plate 603 through the first through groove 704 and the second through groove 709 respectively. 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.

[0045] In the embodiment, as shown in Figure 8 and Figure 9 The feeding auxiliary mechanism further comprises a moving plate 710 arranged symmetrically, the upper end surface of the moving plate 710 is fixedly connected with a flared rod 702 at equal intervals, the lower end surface of the moving plate 710 is fixedly connected with a linkage plate 711 symmetrically, the lower end of the linkage plate 711 is fixedly connected with a slide column 714, when the slide column 714 slides out of the lifting plate 609, the linkage plate 711 is arranged to drive the moving plate 710 to move synchronously, and the flared rods 702 move away from each other to pull the two sides of the lower end surface of the packaging bag.

[0047] Compared with the prior art, the cutting knife 701 is driven to rise synchronously during the process of driving the cone 602 to rise and insert into the bottom of the packaging bag to cut the center of the bottom of the packaging bag, which not only can quickly open a larger opening to make the material flow out of the packaging bag quickly and smoothly, reduces the residence time of the material in the packaging bag, and improves the feeding speed and efficiency, but also the operation of cutting the packaging bag is synchronous with the feeding process, which reduces the operation steps, improves the continuity and efficiency of the operation, makes the feeding process more automated, and reduces the necessity of manual intervention.

[0048] 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.

[0049] The working process and principles involved in the above embodiments are as follows:

[0050] 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.

[0051] In the process of cutting the packaging bag by pushing the cutting knife 701 up close to the bottom of the packaging bag through the lifting column 608, since the lower end of the lifting column 608 is fixedly connected with the disc 708, and the outer surface of the disc 708 is fixedly connected with the linkage rod 707 symmetrically, and the linkage rod 707 is provided with protrusions 706 on both sides, and the protrusions 706 on both sides are staggered with each other, therefore, with the rising of the lifting column 608, the lifting column 608 is affected by the protrusions 706 on both sides, and pushes the linkage rod 707 to reciprocate left and right, and drives the lifting column 608 to move synchronously through the disc 708, so that the lifting column 608 moves horizontally and reciprocally synchronously in the rising process, so that the cutting knife 701 can slide horizontally and reciprocally in the sliding groove 703 when the lifting column 608 pushes the cutting knife 701 close to the center of the bottom of the packaging bag, which not only 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, but also the horizontal reciprocating movement can help to reduce the excessive friction and jamming of the cutting knife 701 with the fibers of the packaging bag in the cutting process, which can effectively avoid the cutting knife 701 from being stuck due to fiber winding, further improve the durability and reliability of the cutting knife 701;

[0052] In the process of rising of the cutting knife 701, since the cutting knife 701 is slidingly connected in the sliding groove 703 opened in the upper end surface of the lifting plate 609, therefore, the cutting knife 701 drives the lifting plate 609 to rise synchronously under the influence of the sliding groove 703, at this time, since the lifting plate 609 is fixedly connected with the fixed plate 612 symmetrically on both sides, and the shaft 613 is arranged between the fixed plates 612 on the same side, and the connecting plate 610 is fixedly connected with the outer surface of the shaft 613, and the supporting plate 601 is fixedly connected with the connecting plate 610 away from the shaft 613, and the conical body 602 is fixedly connected with the upper end surface of the supporting plate 601, therefore, with the rising of the lifting plate 609, the lifting plate 609 can drive the connecting plate 610 to rise synchronously through the fixed plate 612 and the shaft 613 connected on both sides, so that the connecting plate 610 drives the conical body 602 to insert into the lower end surface of the packaging bag on both sides through the supporting plate 601, and fixes the packaging bag, which not only avoids the blockage of material conveying 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 problem caused by the shaking or displacement of the packaging bag, further ensures the stability of the feeding process, avoids the mixing of the packaging bag and the material or the situation that the packaging bag is stuck in the internal corner of the feeding station body 1, thereby reducing the time and effort consumed for cleaning the packaging bag, reducing the risk of failure of the feeding station body 1 caused by the packaging bag residue, reducing the frequency and cost of maintenance of the feeding station body 1;

[0053] In the process of the lifting plate 609 rising to insert the conical body 602 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 rotating shaft 613 is fixedly connected with the push plate 614 at both ends, 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 fixedly connected to the vertical plate 611. Therefore, in the process of the rotating shaft 613 rising away from the vertical plate 611 below, the end of the push plate 614 connected to the outer surface of the rotating shaft 613 moves from above the rotating shaft 613 to below the rotating shaft 613, and the push rod 616 slides in the communication groove 615 of the push plate 614 and rotates the rotating shaft 613 through the push plate 614. In the process of rotating the rotating shaft 613, the connecting plate 610 rotates synchronously, the supporting plate 601 connected to one side of the connecting plate 610 rotates upward, and the two supporting plates 601 drag the packaging bag 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 the material in the packaging bag can flow out from the center of the bottom of the packaging bag when the two sides of the packaging bag are dragged to rotate upward and close to each other. The material flowing out 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, and shorten the time required for each feeding, but also can reduce the need for manual intervention due to the smooth flow of the material. The operator can focus more on other production tasks, reduce the time and energy consumed for cleaning or adjusting the feeding equipment, and improve the work efficiency.

[0054] 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.
