Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical production technology, specifically relating to a sugar-cutting device for cutting polysaccharides. Background Technology

[0002] Polysaccharides (such as bacterial capsular polysaccharides) are often used as key raw materials in vaccines, biopharmaceuticals, and other fields. Their preparation requires cutting the polysaccharides into fragments of specific sizes to meet the requirements of subsequent washing, packaging, and other processes. In existing pharmaceutical manufacturing processes, pre-treated polysaccharides (such as pneumococcal capsular polysaccharides or Neisseria meningitidis capsular polysaccharides) need to be crushed or cut into fragments according to process requirements. Currently, the commonly used method is manual operation, where operators use tools such as tweezers, scissors, or spoons to crush or cut them. However, this existing technology has the following significant drawbacks: 1) Poor shearing uniformity affects product consistency: The pre-treated polysaccharides are quite hard, making it difficult to crush or shear them evenly manually using traditional tools (such as scissors and spoons). Significant differences in the techniques and force applied by different operators result in polysaccharide fragments of varying sizes, directly impacting the uniformity and quality stability of subsequent products and increasing the difficulty of process control.

[0003] 2) Low manual efficiency and high risk of contamination: Manual cutting of polysaccharides is time-consuming. Taking the commercial production of pneumococcal capsular polysaccharide type 6A as an example, the traditional cutting step requires four people to operate continuously for more than 20 minutes, which is inefficient. In addition, the products are exposed to the air for a long time, which increases the risk of microbial contamination, dust contamination, etc., and does not meet the aseptic and standardized requirements of pharmaceutical production.

[0004] 3) Tool wear leading to impurity introduction: The joints of traditional tools (such as scissors) are prone to wear after repeated use, which may cause metal shavings or other impurities to fall off and directly contaminate the product. Especially in pharmaceutical production, the introduction of impurities may affect the purity and safety of polysaccharides, and even lead to product defects.

[0005] 4) The operation is labor-intensive and poses health risks: Manually cutting high-hardness polysaccharides repeatedly requires maintaining a fixed hand gesture for a long time, which is labor-intensive. Long-term operation can easily cause health problems such as muscle strain and joint damage in the hands of operators, which does not meet the requirements of ergonomics in industrial production.

[0006] To address the aforementioned issues, existing polysaccharide shearing processes urgently require a more efficient device to solve problems such as poor uniformity, low efficiency, high pollution risk, and high labor intensity caused by manual operation. Utility Model Content

[0007] The purpose of this invention is to propose a sugar-cutting device for cutting polysaccharides, replacing traditional manual operation, effectively solving the defects in the existing technology, providing an efficient, safe and stable cutting solution for the production of polysaccharide drugs, and improving the automation level and product quality of drug production.

[0008] The above objectives are achieved through the following technical solutions: A polysaccharide-cutting device includes a polysaccharide-cutting base, a thinning saw, and a polysaccharide-cutting blade assembly. The polysaccharide-cutting blade assembly includes a polysaccharide positioning support component, a blade holder, and blade units. Each blade unit consists of multiple (two or more, preferably more than 10, such as 13 to 30) blade bodies arranged parallel and equidistantly based on the blade holder. The polysaccharide positioning support component is detachably mounted on the polysaccharide-cutting base, and the polysaccharide positioning support component has blade clearance holes adapted to the blade units. The polysaccharide-cutting base is provided with a thinning guide structure, and the thinning saw slides with the polysaccharide-cutting base through the thinning guide structure to thin and layer the polysaccharide to be cut located on the polysaccharide positioning support component.

[0009] Preferably, the sugar-free base includes a liquid collection box, inside which four positioning support columns are distributed in a rectangular structure. Each positioning support column includes a lower support part and an upper positioning connection part that are coaxially integrally formed. The polysaccharide positioning support component is provided with mating holes that are adapted to the positioning support columns. The polysaccharide positioning support component is detachably positioned and installed on the four positioning support columns of the sugar-free base through the mating holes.

[0010] Preferably, the height of the positioning support column is greater than the height of the blade body.

[0011] Preferably, the thinning guide structure includes two guide units symmetrically arranged on both sides of the collection box. Each guide unit consists of two or more linear guide holes of different heights, with the different heights of the linear guide holes corresponding to the different thinning thickness requirements of the polysaccharide to be broken. In use, according to the required thickness of the polysaccharide to be broken, the appropriate height of the linear guide hole is selected. The thinning saw is passed through the two linear guide holes of equal height in the two guide units, with the saw blade facing the polysaccharide. Both hands are used to apply force to both ends of the thinning saw, pulling it back and forth in the left-right direction to achieve thinning.

[0012] Preferably, the polysaccharide positioning support assembly includes a lower polysaccharide support plate and an upper gravity pressure plate, and both the lower polysaccharide support plate and the upper gravity pressure plate are provided with blade clearance holes adapted to the blade unit.

[0013] Preferably, there are two or more sets of sugar-cutting knife groups. The number of blade bodies and the blade spacing of the blade units in different sugar-cutting knife groups are different, so as to select the appropriate sugar-cutting knife group for use as needed.

[0014] Preferably, the tool holder includes a blade mounting plate and a pressure plate; the blade mounting plate has a plurality of blade positioning and mounting holes that correspond one-to-one with the blade body in the blade unit, and the blade body is detachably mounted on the blade mounting plate through the positioning and mounting holes; the pressure plate is detachably fitted to the top of the blade mounting plate to fix the blade unit.

[0015] Preferably, the pressure plate is detachably and securely mounted to the top of the blade mounting plate by screws or clips.

[0016] Preferably, the blade body includes an integrally formed blade head and blade body, which together form a T-shaped structure; the cross-section of the blade positioning and mounting hole is a T-shaped structure adapted to the blade body.

[0017] Preferably, the bottom of the blade holder is provided with four blade guard posts arranged in a rectangular structure, and the length of the blade guard posts is greater than the height of the blade body.

[0018] Preferably, the top of the tool holder is provided with an operating handle.

[0019] Preferably, the sugar-cutting base is provided with protruding nails for placing the polysaccharide clamp.

[0020] This technical solution has the following beneficial effects: 1) Improved shearing uniformity and ensured product consistency. This technical solution uses multiple sets of sugar-cutting blades with different numbers of blades and blade spacing to precisely control the size of polysaccharide fragments using standardized blade spacing. Combined with a thinning saw that uses a guiding structure to pre-process the polysaccharides in layers, this effectively solves the problem of uneven fragment size caused by differences in technique and force during manual shearing. This ensures uniform polysaccharide fragment size and significantly improves product uniformity and quality stability.

[0021] 2) Significantly improves production efficiency and reduces operation time. The equipment adopts a mechanized operation mode. Taking the production of pneumococcal capsular polysaccharide of type 6A as an example, the workload that traditionally requires 4 people to operate for more than 20 minutes can be completed quickly by only 2 people in 10 minutes through the "thinning and layering + double pressing and cutting" process of this equipment. At the same time, multiple sets of sugar-cutting blades can be quickly replaced to adapt to different specifications of cutting requirements, which greatly improves production efficiency and significantly shortens operation time.

[0022] 3) Reduced contamination risk and compliance with aseptic production requirements. The collection box effectively collects shearing waste liquid, preventing contamination of the workbench; increased operating speed shortens polysaccharide exposure time; the base protrusions facilitate standardized placement of polysaccharide clamps; and the gravity-pressure plate restrains the polysaccharide after cutting to prevent sticking to the blade, reducing manual cleaning steps. Multiple design features reduce the risk of contamination from microorganisms and dust, strictly complying with the requirements of aseptic pharmaceutical production.

[0023] 4) Preventing the introduction of impurities and ensuring product purity. The blade body and blade holder adopt a T-shaped detachable connection design, which allows the worn blade body to be replaced individually, avoiding the metal shavings that traditional tools lose due to wear; the blade guard design prevents the blade from wearing down by touching the bottom, and the gravity pressing plate has no mechanical connecting parts that wear, reducing the introduction of impurities from multiple aspects and effectively ensuring product purity.

[0024] 5) Reduced labor intensity and ergonomic design. An ergonomic handle is located at the top of the blade holder, making the pressing process more effortless and stable, effectively avoiding hand strain and joint damage caused by repeated manual cutting. The standardized "positioning-thinning-cutting" operation process simplifies the work steps, further reducing the labor intensity of operators.

[0025] 6) The thinning guide structure achieves precise control of the thinning thickness through unequal height linear holes. Combined with the modular design of the blade and tool holder, it effectively reduces maintenance costs. The blade guard supports the blade in mid-air, preventing wear and accidental contact, achieving an innovative breakthrough in precise thickness control, economy, and safety protection.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0029] Therefore, the following detailed description of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example 1 This embodiment discloses a sugar-cutting device for shearing polysaccharides. As a preferred embodiment of this technical solution, it includes a sugar-cutting base 1, a thinning saw 2, and two or more sets of replaceable sugar-cutting blades. Figure 1 As shown, each sugar-cutting knife set includes a polysaccharide positioning support component 3, a knife holder 4, and a blade unit. The blade unit consists of several blade bodies 5 arranged parallel to and at equal intervals based on the knife holder 4. The polysaccharide positioning support component 3 is detachably mounted on the sugar-cutting base 1, and the polysaccharide positioning support component 3 has blade clearance holes 3.4 adapted to the blade unit. Depending on the washing and dispensing characteristics of the polysaccharides, the sugar-cutting requirements have different target sizes. By setting up multiple sets of sugar-cutting knife sets for interchangeable use, the number of blade bodies 5 and the blade spacing of the blade unit in different sugar-cutting knife sets are different, which can meet the sugar-cutting requirements of different target sizes. This embodiment takes three sets of interchangeable sugar-cutting knife sets as an example. Specifically: The first set: A blade holder 4 is set to be 18cm long and 18cm wide. Based on this, a blade unit with 18 blade bodies 5 is set. Each blade body 5 is 14cm long, 7cm high, and 0.1cm thick, with a spacing of 0.5cm between adjacent blade bodies 5. The polysaccharide positioning support component 3 can be machined from 316L stainless steel, and 18 blade clearance holes 3.4, each 14.2cm long and 0.12cm wide, are correspondingly provided.

[0031] The second set: A blade holder 4 is 18cm long and 18cm wide. Based on this, a blade unit with 13 blade bodies 5 is installed. Each blade body 5 is 14cm long, 7cm high, and 0.1cm thick, with a spacing of 0.9cm between adjacent blade bodies 5. The polysaccharide positioning support component 3 can be machined from 316L stainless steel, and 13 blade clearance holes 3.4, each 14.2cm long and 0.12cm wide, are correspondingly provided.

[0032] The third set includes a blade holder 4, 18cm long and 18cm wide, upon which a blade unit with 30 blade bodies 5 is installed. Each blade body 5 is 14cm long, 7cm high, and 0.1cm thick, with a 0.4cm spacing between adjacent blade bodies 5. The polysaccharide positioning support component 3 can be machined from 316L stainless steel, and 30 blade clearance holes 3.4, each 14.2cm long and 0.12cm wide, are correspondingly provided.

[0033] By setting up multiple sets of sugar-cutting blades with different numbers of blade bodies and blade spacing, the size of the sugar-cut pieces can be adjusted by utilizing the blade spacing to meet the requirements of different processes for the size of polysaccharide fragments (such as different specifications required for washing and packaging), thus solving the problem of poor uniformity in manual cutting.

[0034] A thinning guide structure 6 is provided on the sugar-cutting base 1. The thinning saw 2 slides with the sugar-cutting base 1 through the thinning guide structure 6 and is used to thin and layer the polysaccharide to be cut on the polysaccharide positioning support component 3. The main function of the thinning saw 2 is to thin the polysaccharide to be cut and to cut the polysaccharide to be cut into the target thickness range according to different process requirements. The specific operation is as follows: (1) Hold any end of the thinning saw 2 and put it into the guide structure 6 so that the saw blade is facing the polysaccharide; (2) Use both hands to act on both ends of the thinning saw 2, with the saw blade facing the polysaccharide and pull back and forth in the direction of left and right hands. At the same time, move the thinning saw 2 along the thinning guide structure 6 until the thinning saw completely passes through the polysaccharide. According to the size design of each structure in this embodiment, the length of the saw body of the thinning saw 2 is 26cm and the thickness is 0.1cm. The two long edges of the saw body are provided with saw teeth and can be flipped for use. Furthermore, the thinning saw 2 first layers the high hardness polysaccharide through the sliding guide, which reduces the subsequent shearing resistance and avoids uneven shearing of the polysaccharide due to its high hardness. Thinning and layering makes the polysaccharide structure easier to cut with the blade, while reducing blade wear and improving shearing efficiency.

[0035] This embodiment uses pneumococcal capsular polysaccharide type 6A as an example. In commercial production, the amount of polysaccharide required is over 20 minutes and continuous cutting by four people. Using the polysaccharide-cutting device of this technology, only two pressing operations are needed to complete one polysaccharide division. The first pressing cutter 4 cuts the polysaccharide into strips, and the second pressing cutter 4 after rotating the polysaccharide 90° cuts it into blocks. Under the same sugar quantity, it is estimated that two people can complete the process within 10 minutes. The polysaccharide-cutting device operates quickly and cuts easily, significantly reducing the exposure time of biological products to air and lowering the risk of contamination.

[0036] Example 2 This embodiment discloses a sugar-cutting device for cutting polysaccharides. As a preferred implementation of this technical solution, based on embodiment 1, considering that there is residual liquid in the polysaccharide to be cut, a small amount of liquid will seep out during the cutting operation, the sugar-cutting base 1 is set up including a liquid collection box 1.1. The liquid collection box 1.1 is used to collect waste liquid for centralized treatment, avoiding liquid dripping and contaminating the workbench or biological products, and meeting the aseptic requirements of pharmaceutical production.

[0037] The collection box 1.1 has a rectangular internal structure with four positioning support columns 1.2. Each positioning support column 1.2 includes a coaxially integrated lower support part 1.21 and an upper positioning connection part 1.22. The polysaccharide positioning support assembly 3 is provided with mating holes 3.1 that are adapted to the positioning support columns 1.2. The polysaccharide positioning support assembly 3 is detachably positioned and installed on the four positioning support columns 1.2 of the sugar cutting base 1 through the mating holes 3.1, ensuring the stability of the polysaccharide during shearing and avoiding inconsistent fragment sizes due to shaking. Specifically, the diameter of the lower support part 1.21 is larger than the diameter of the mating hole 3.1, and the diameter of the mating hole 3.1 is slightly larger than the diameter of the upper positioning connection part 1.22. Thus, the mating hole 3.1 fits onto the upper positioning connection part 1.22, and the lower support part 1.21 supports and raises the polysaccharide positioning support assembly 3, so that the blade body 5 can smoothly pass through the blade clearance hole 3.4 to cut the polysaccharide.

[0038] Furthermore, the height of the positioning support column 1.2 is greater than the height of the blade body 5. Thus, during the sugar cutting process, after the blade body 5 smoothly passes through the blade clearance hole 3.4, the blade holder 4 can rest on the positioning support column 1.2. The interaction between the blade holder 4 and the positioning support column 1.2 can prevent the blade body 5 from touching the bottom and wearing out, thereby protecting the blade life.

[0039] Example 3 This embodiment discloses a polysaccharide-cutting device. As a preferred implementation of this technical solution, based on embodiment 1 or 2, its thinning guide structure 6 includes two guide units 6.1 symmetrically arranged on both sides of the liquid collection box 1.1. Each guide unit 6.1 consists of two or more linear guide holes 6.11 of unequal height. The different heights of the linear guide holes 6.11 correspond to different thinning thickness requirements of the polysaccharide to be cut. In use, according to the required thickness of the polysaccharide to be cut, the appropriate height of the linear guide hole 6.11 is selected. The thinning saw 2 is passed through the two equal height linear guide holes 6.11 in the two guide units 6.1. Both hands are applied to the two ends of the thinning saw 2, and it is pulled along the linear guide holes 6.11 to achieve thinning. That is, by selecting the equal height linear guide holes 6.11, the moving height of the thinning saw 2 is constrained, and the thickness of the polysaccharide thinning is precisely controlled. This design standardizes the thinning thickness, avoids the error of manual operation based on experience, ensures that the thickness of the subsequently cut polysaccharide blocks is consistent, and improves product uniformity.

[0040] Example 4 This embodiment discloses a polysaccharide-cutting device for shearing polysaccharides. As a preferred implementation of this technical solution, based on any of embodiments 1-3, the polysaccharide positioning support component 3 includes a lower polysaccharide support plate 3.2 and an upper gravity-pressure plate 3.3. Both the lower polysaccharide support plate and the upper gravity-pressure plate 3.3 are provided with blade clearance holes 3.4 adapted to the blade unit, and mating holes 3.1 adapted to the four positioning support columns 1.2 on the cutting base. In use, the lower polysaccharide support plate 3.2 is first installed on the cutting base 1, then the polysaccharide to be cut is placed on the lower polysaccharide support plate 3.2, and finally the upper gravity-pressure plate 3.3 is constrained to the polysaccharide by the cutting base 1. The upper gravity-pressure plate 3.3, based on its own weight and the lower polysaccharide support plate 3.2, compresses and fixes the polysaccharide to be cut, preparing for the cutting operation. It can fix the polysaccharide without additional power, preventing displacement during shearing. During this process, a small amount of residual liquid in the polysaccharide to be cut is squeezed out and accumulates on the sugar-cutting base 1. When the blade body 5 is removed after the polysaccharide cutting is completed, the constraint of the gravity-pressing sugar plate 3.3 above can effectively prevent the polysaccharide from sticking to the blade, reduce manual cleaning steps, and reduce the risk of contamination.

[0041] Example 5 This embodiment discloses a sugar-cutting device for shearing polysaccharides. As a preferred embodiment of this technical solution, based on any of the embodiments 1-4, its blade holder 4 includes a blade mounting plate 4.1 and a pressure plate 4.2. The blade mounting plate 4.1 has a plurality of blade positioning mounting holes 4.3 corresponding one-to-one with the blade bodies 5 in the blade unit. The blade bodies 5 are detachably mounted on the blade mounting plate 4.1 through the positioning mounting holes. The pressure plate 4.2 is detachably attached to the top of the blade mounting plate 4.1 by screws 4.4 to fix the blade unit. In this embodiment, the blade bodies 5 and the blade holder 4 are detachably connected. When the blade bodies 5 become dull due to prolonged use, the worn blade bodies 5 can be replaced individually without replacing the entire blade holder 4 and blade unit, reducing maintenance costs.

[0042] Furthermore, different sugar-cutting knife sets in the sugar-cutting device can share the same set of blade bodies 5. Taking three sets of sugar-cutting knife sets as an example, the sugar-cutting device includes one sugar-cutting base 1, one thinning saw 2, three sets of polysaccharide positioning support components 3, three blade mounting plates 4.1, one pressure plate 4.2, and at least 30 blade bodies 5. The three blade mounting plates 4.1 are respectively provided with 13, 18, and 30 blade positioning mounting holes 4.3, and the three sets of polysaccharide positioning support components 3 are respectively provided with 13, 18, and 30 blade clearance holes 3.4. By selecting different numbers of blade bodies 5, corresponding blade mounting plates 4.1, corresponding polysaccharide positioning support components 3, and pressure plates 4.2 for assembly, different models of sugar-cutting knife sets can be obtained. That is, to replace the sugar-cutting knife sets, only the polysaccharide positioning support components 3 and blade mounting plates 4.1 need to be replaced. Thus, modular design reduces the number of parts, improving the economy and flexibility of the device.

[0043] Example 6 This embodiment discloses a sugar-cutting device for shearing polysaccharides. As a preferred embodiment of this technical solution, based on Embodiment 5, the blade body 5 includes an integrally formed blade head 5.1 and blade body 5.2, which, when combined, give the blade body 5 a T-shaped cross-section. The blade positioning mounting hole 4.3 also has a T-shaped cross-section adapted to the blade body 5. The T-shaped cross-section of the blade body 5 and the blade positioning mounting hole, along with the stepped structure of the blade head 5.1 and blade body 5.2, prevents lateral displacement of the blade body 5 during shearing, and enhances stability through mechanical locking. This design ensures that the blade body 5 maintains precise positioning during high-frequency use, avoids size deviations in fragments due to loosening, and extends the service life of the blade body 5.

[0044] Example 7 This embodiment discloses a sugar-cutting device for shearing polysaccharides. As a preferred embodiment of this technical solution, based on any of embodiments 1-6, the bottom of the blade holder 4 is provided with four rectangularly arranged blade guard posts 7, and the length of the blade guard posts 7 is greater than the height of the blade body 5. When the blade holder 4 is placed upside down, the blade guard posts 7 first contact the tabletop, suspending the blade and preventing it from contacting and wearing down with hard objects. Simultaneously, placing the blade holder 4 upside down prevents the operator from accidentally touching the blade, improving the safety of the device.

[0045] Example 8 This embodiment discloses a sugar-cutting device for shearing polysaccharides. As a preferred embodiment of this technical solution, based on any of the embodiments 1-7, an operating handle 8 is provided on the top of the blade holder 4. This ergonomic design facilitates the operator's application of force with both hands, making the pressing process smoother and less strenuous. This design reduces hand muscle strain (such as joint damage caused by traditional manual shearing) while ensuring uniform pressing pressure and improving shearing accuracy.

[0046] Example 9 This embodiment discloses a polysaccharide-cutting device. As a preferred embodiment of this technical solution, based on any of embodiments 1-8, the polysaccharide-cutting base 1 is provided with protruding nails 9 for placing polysaccharide clamps. The polysaccharide clamps are used to grip moving polysaccharides. Placing the polysaccharide clamps on the protruding nails 9 standardizes the placement of tools and avoids contamination (such as dust and microbial adhesion) caused by haphazard tool placement. Simultaneously, the protruding nail 9 design saves operating table space, making the production process more orderly and meeting the requirements of standardized pharmaceutical production.
