Description

Technical Field

[0001] This application relates to the pharmaceutical field, and more specifically, to a sieve plate assembly and a tablet loading machine for processing zinc selenium protein chewable tablets. Background Technology

[0002] In the field of solid oral dosage forms, protein zinc selenium chewable tablets are a common dietary supplement. Their production process requires high-speed, precise bottling or blister packing using automated tablet loading machines. These chewable tablets typically have a biconvex circular structure, a texture suitable for chewing, and high requirements for tablet integrity.

[0003] In the automated tableting process of zinc selenium protein chewable tablets, the sieve assembly is a key functional unit that ensures the filled tablets meet specifications. These chewable tablets generally adopt a biconvex circular or elliptical design with a continuous, smooth, curved outline at the edges, and their texture must meet the requirements for palatability and integrity for chewing.

[0004] Currently, the sieve plate assemblies of film loading machines mainly adopt single-layer or multi-layer fixed sieve structures. The sieve plates are mostly made of stainless steel or engineering plastics, and a hydrophobic coating can be applied to the surface to reduce powder adhesion. The sieve holes are mainly circular, rectangular, or elongated, and the basic size screening is achieved through static geometric constraints. Summary of the Invention

[0005] This application provides a sieve plate assembly and a tablet loading machine for processing zinc selenium protein chewable tablets, which can improve the product quality of the screened tablets.

[0006] Specifically, this application is implemented through the following technical solution:

[0007] One aspect of this application provides a sieve plate assembly for a tablet loading machine for processing zinc-selenium protein chewable tablets, comprising:

[0008] A first sieve plate and a second sieve plate are coaxially connected. The first sieve plate and the second sieve plate are circular sieve plates. The first sieve plate has an arc-shaped opening extending in the circumferential direction, and the second sieve plate has a straight opening extending in the radial direction. The first sieve plate and the second sieve plate can rotate coaxially relative to each other.

[0009] The sieve plate assembly includes at least a first position, where the arc-shaped opening and the straight opening intersect to form a sieve hole.

[0010] Optionally, the arc-shaped openings include multiple ones, and the arc length of the multiple arc-shaped openings will gradually increase along the radial direction from the center to the circumference of the first sieve plate.

[0011] Optionally, the linear openings include a plurality of holes and are distributed circumferentially along the second sieve plate.

[0012] Optionally, the first screen plate includes a plurality of first screening sections symmetrically distributed along its center, and the second screen plate includes a plurality of second screening sections symmetrically distributed along its center.

[0013] The first screening section has multiple arc-shaped openings, and one of the multiple second screening sections is a drop area that runs through the second screen plate. The other second screening sections have multiple straight openings.

[0014] Optionally, the sieve plate assembly further includes an adjusting plate. The second sieve plate is hollow, and the adjusting plate is coaxially installed inside the second sieve plate and rotatably connected to the second sieve plate. The adjusting plate has the same straight opening as the second sieve plate.

[0015] Optionally, a limiting hole is provided on the side wall of the second sieve plate, and a limiting rod is fixed to the side wall of the adjusting plate, with the limiting rod extending out from the limiting hole.

[0016] Optionally, the sieve plate assembly further includes a storage cylinder, the bottom wall of which is a first sieve plate, and the storage cylinder further includes a rotating motor, the output end of which is coaxially connected to the first sieve plate.

[0017] Optionally, the storage cylinder includes a removable sealing cover.

[0018] Another aspect of this application provides a tablet loading machine, including the sieve plate assembly of the tablet loading machine for processing protein zinc selenium chewable tablets as described in any of the preceding claims.

[0019] This application provides a sieve plate assembly and a tablet loading machine for processing zinc-selenium protein chewable tablets, comprising a first sieve plate with arc-shaped openings and a second sieve plate with straight openings. After the zinc-selenium protein chewable tablets enter the sieve plate assembly, they undergo preliminary screening on the first sieve plate. Because the first sieve plate has arc-shaped openings, it can screen out zinc-selenium protein chewable tablets whose curvature is the same as or less than that of the arc-shaped openings, allowing them to enter the arc-shaped openings. Subsequently, the first sieve plate begins to rotate, moving the sieve plate assembly to a first position, at which point the arc-shaped openings intersect with the straight openings on the second sieve plate to form sieve holes. This process further screens out tablets that have entered the arc-shaped openings and simultaneously align with the straight openings. This two-step screening process effectively improves the accuracy of screening. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0028] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0029] refer to Figure 1 and Figure 2 This application provides a sieve plate assembly for a tablet loading machine for processing zinc-selenium protein chewable tablets, including a first sieve plate 100 and a second sieve plate 200 coaxially connected. Both the first sieve plate 100 and the second sieve plate 200 are circular sieve plates. The first sieve plate 100 has an arc-shaped opening 110 extending circumferentially, and the second sieve plate 200 has a straight opening 210 extending radially. The first sieve plate 100 and the second sieve plate 200 are coaxially rotatable relative to each other. The sieve plate assembly includes at least a first position where the arc-shaped opening 110 and the straight opening 210 intersect to form a sieve hole 300.

[0030] After the zinc-selenium protein chewable tablets enter the sieve assembly, they undergo preliminary screening on the first sieve plate 100. Since the first sieve plate 100 has arc-shaped openings 110, it can screen out zinc-selenium protein chewable tablets whose curvature is the same as or less than that of the arc-shaped openings 110, allowing them to enter the arc-shaped openings 110. Subsequently, the first sieve plate 100 begins to rotate, moving the sieve assembly to the first position. At this point, the arc-shaped openings 110 intersect with the straight openings 210 on the second sieve plate 200 to form sieve holes 300. This process further screens out tablets that have entered the arc-shaped openings 110 and simultaneously align with the straight openings 210. This two-step screening process effectively improves the accuracy of screening. The zinc-selenium protein chewable tablets may be oval or round, with convex shapes on both sides. On the one hand, it can match the curvature of the arc-shaped opening 110. That is, when the curvature of the outer arc surface of the tablet is smaller than that of the arc-shaped opening 110, it can pass smoothly through the arc-shaped opening 110, thereby initially screening out tablets that are too large / too thick due to mismatched curvature, deformed tablets with distorted curvature, and adhered tablets. After the first sieve plate 100 rotates to the first position, the tablets to be further inserted must meet the requirement that the width dimension is less than or equal to the width of the straight opening 210, and there should be no local protrusions or burrs for them to pass through; this step intercepts critically thick tablets, tablets with edge burrs, and asymmetrical deformations. This ensures that the tablets that finally pass through the sieve plate assembly meet the requirements of the tablet loading machine in terms of shape and size, thereby improving the product quality of the screened tablets.

[0031] Combination Figure 3 and Figure 4 In one embodiment, multiple arc-shaped openings 110 are included, and the arc length of the multiple arc-shaped openings 110 gradually increases along the radial direction from the center to the circumference of the first sieve plate 100. The sieve plate assembly of this embodiment forms a step-by-step screening system by setting multiple arc-shaped openings 110 with increasing arc length and constant width radially on the first sieve plate 100, combined with the straight openings 210 of the second sieve plate 200. Firstly, the multiple arc-shaped openings 110 form parallel pre-screening sites, allowing tablets of different sizes to simultaneously complete curvature matching. Small tablets are embedded in the inner short arc holes, while large tablets are captured in the outer long arc holes, effectively improving pre-screening efficiency. Furthermore, the radial gradient distribution of arc length matches the tablet diffusion behavior, with small tablets frequently residing inwards and large tablets centrifugally shifting outwards, making the screening process more precise. Multiple screening points at different locations are formed, increasing the number of sieve holes 300, allowing for a wider range of screening of protein zinc selenium chewable tablets, and improving screening efficiency.

[0032] Combination Figure 5In one embodiment, multiple linear openings 210 are distributed circumferentially along the second sieve plate 200. When the first sieve plate 100 rotates the arc-shaped opening 110 containing the tablet to the area intersecting with the second sieve plate 200, the multiple circumferentially distributed linear openings 210 form a continuous detection zone, effectively avoiding missed screening due to excessive rotation speed. Multiple linear openings 210 allow for parallel fine screening operations, improving screening efficiency.

[0033] refer to Figure 5 In one embodiment, the first sieve plate 100 includes a plurality of first screening sections 101 symmetrically distributed along its center, and the second sieve plate 200 includes a plurality of second screening sections 201 symmetrically distributed along its center. The first screening sections 101 have a plurality of arc-shaped openings 110, and one of the plurality of second screening sections 201 is a drop area that extends entirely through the second sieve plate 200, while the other second screening sections 201 have a plurality of straight openings 210. First, the arrangement of multiple screening sections forms multiple independent screening areas, allowing the screening process to be carried out simultaneously in multiple areas. Second, the design of the drop area solves the problem of tablet jamming. In actual screening, some tablets may get stuck in the arc-shaped openings 110 but fail to fall through the straight openings 210. When the sieve plate assembly rotates, these stuck tablets are carried to the drop area along with the rotation of the sieve plate. Since the drop area extends entirely through the second sieve plate 200, it can be fan-shaped. The tablets can then smoothly detach from the arc-shaped openings 110 and fall into the designated area. This design effectively prevents tablets from clogging in the arc-shaped opening 110, ensuring the continuity and smoothness of the screening process and improving cleaning efficiency.

[0034] Combination Figure 6 In one embodiment, the sieve plate assembly further includes an adjusting plate 400. The second sieve plate 200 is a hollow shell, and the adjusting plate 400 is coaxially mounted inside the second sieve plate 200 and rotatably connected to it. The adjusting plate 400 has straight openings 210 identical to those on the second sieve plate 200. When the adjusting plate 400 rotates relative to the second sieve plate 200, the overlapping area of ​​the straight openings 210 changes, thereby adjusting the opening width. This allows the sieve plate assembly to adapt to different sizes of protein zinc selenium chewable tablets, meeting diverse production needs and enhancing the versatility and flexibility of the equipment. This adjustable design simplifies the maintenance and adjustment process. Traditional sieve plate assemblies often require replacing the entire sieve plate to change the screening size, which is cumbersome and costly. In this embodiment, however, the size of the sieve openings 300 can be quickly adjusted simply by rotating the adjusting plate 400, without disassembling or replacing parts, significantly reducing maintenance costs and downtime, and improving production efficiency.

[0035] Combination Figure 5In one embodiment, a limiting hole 220 is formed in the side wall of the second sieve plate 200, and a limiting rod 410 is fixed to the side wall of the adjusting plate 400, extending from the limiting hole 220. This design, by forming a limiting hole 220 in the side wall of the second sieve plate 200 and fixing a limiting rod 410 to the side wall of the adjusting plate 400 and having it extend from the limiting hole 220, achieves control over the range of motion of the adjusting plate 400. The width range of the limiting hole 220 determines the range of angles that the adjusting plate 400 can rotate, thereby ensuring that the adjusting plate 400 does not exceed the predetermined range when adjusting the width of the straight opening 210. This ensures the stability and safety of the adjustment process.

[0036] In one embodiment, the sieve assembly further includes a storage cylinder A, the bottom wall of which serves as a first sieve plate 100. The storage cylinder A also includes a rotary motor 500, the output end of which is coaxially connected to the first sieve plate 100. Firstly, the bottom wall of the storage cylinder A serves as the first sieve plate 100, integrating storage and screening functions, simplifying the equipment structure, reducing material transfer steps, and improving production efficiency. Secondly, the rotary motor 500 drives the first sieve plate 100 to rotate, achieving continuous screening of tablets, and working with the second sieve plate 200 to form dynamic sieve holes 300, improving screening efficiency and accuracy. Furthermore, the storage cylinder A can be connected to a vibration motor, which causes the first sieve plate 100 to vibrate, helping to evenly distribute the tablets, preventing clogging, and further improving the screening effect.

[0037] In one embodiment, the storage cylinder A includes a removable sealing cover (not shown in the figure). The sealing cover effectively isolates external impurities, preventing the zinc selenium protein chewable tablets from being contaminated during processing and ensuring product quality.

[0038] This application also provides a tablet loading machine, including a sieve plate assembly of the tablet loading machine for processing zinc-selenium chewable tablets provided in any of the above embodiments. This tablet loading machine utilizes the efficient screening function of the sieve plate assembly to ensure that the zinc-selenium protein chewable tablets entering subsequent tablet loading processes meet size and shape requirements, thereby improving tablet loading efficiency and finished product quality.

[0039] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
