Description

Technical Field

[0001] This utility model relates to the field of medical material cutting equipment technology, and in particular to a cutting fixture and cutting system for strip-shaped materials. Background Technology

[0002] In the field of biomedical testing, fiber carrier sheets containing anticoagulants (such as lithium heparin) are important testing consumables that need to be cut to specific lengths to meet the requirements of different testing equipment or experimental procedures. However, existing methods for cutting strip materials have many problems and cannot meet the needs for efficient, accurate, and safe cutting.

[0003] Traditional cutting methods rely heavily on manual cutting with ordinary tools. This method is not only inefficient but also makes it difficult to guarantee cutting accuracy. Due to the arbitrariness of manual operation, the lengths of the cut strips are often inconsistent, seriously affecting subsequent use and product quality. Especially in large-scale production or scenarios requiring the cutting of a large number of strips, the low efficiency and high error rate of manual cutting can significantly limit production progress and cost control.

[0004] Furthermore, existing cutting tools have significant safety shortcomings. The cutting edge of ordinary knives is usually directly exposed, and operators can easily be cut by the blade during cutting, posing a considerable safety hazard. This is especially true when handling strip-shaped materials of special materials, such as fiber carrier sheets containing bioactive ingredients or chemical reagents; accidental cuts from the knife can not only cause bodily injury to the operator but may also lead to material contamination or leakage.

[0005] While some cutting devices improve cutting efficiency and precision to a certain extent, they are complex in structure, expensive, and lack flexibility. These devices are often designed for specific strip materials and cutting specifications, making it difficult to adapt to different materials and diverse cutting needs. When cutting strip materials of different lengths or materials, it is often necessary to replace the entire cutting device or make complex adjustments, which is cumbersome, time-consuming, and labor-intensive.

[0006] Therefore, developing a strip material cutting fixture and system that is efficient, accurate, safe, and flexible enough to adapt to different cutting needs is of great practical significance. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cutting fixture and cutting system for strip materials, so as to overcome the defects of low efficiency, poor operation safety and insufficient adaptability in the cutting of strip materials in the prior art.

[0008] To achieve the above objectives, on the one hand, this utility model provides a cutting fixture for strip-shaped materials, comprising: operating base; Multiple cutting blades are spaced apart from each other on the bottom surface of the operating base plate, with the blades facing downwards; and An elastic buffer is configured to conceal the cutting edge of the cutting blade in a first state, and to elastically compress under external pressure in a second state, thereby exposing the cutting edge to cut the arranged strip material. The elastic buffer body is able to rebound to the first state after the external pressure is released.

[0009] Furthermore, the elastic buffer body has a slit for the cutting blade to pass through. During the cutting process, the cutting blade is forced through the slit by the extrusion fixture to cut the strip material.

[0010] Furthermore, the elastic buffer is a sponge pad; or, the elastic buffer includes an upper sponge layer near the cutting edge of the cutting blade and a lower silicone layer located at the bottom of the upper sponge layer.

[0011] Furthermore, the cutting blade is a straight blade, and they are arranged at equal intervals in the transverse direction, with the spacing between adjacent blades matching the length of the strip material to be cut.

[0012] Furthermore, the operating base plate is formed from hardwood, and the blade is integrated with the operating base plate through an embedded curing process; the distance between the blades is different between different cutting fixtures to adapt to different cutting requirements of strip materials.

[0013] Furthermore, the operating base plate is provided with standardized blade mounting positions. By selecting different numbers of blades and installing them in different mounting positions, different cutting spacing combinations can be formed to adapt to different cutting requirements of strip materials.

[0014] Furthermore, the blade mounting position includes equidistant mounting slots, and the spacing between adjacent mounting slots is an integer multiple of the minimum cutting unit.

[0015] Furthermore, the thickness of the elastic buffer is 1.1 to 1.3 times the protrusion height of the blade, to ensure that the blade is completely hidden when not in use and can penetrate smoothly under pressure.

[0016] Furthermore, the strip material is a fiber carrier sheet containing an anticoagulant, the anticoagulant including lithium heparin.

[0017] On the other hand, this utility model provides a cutting system, including: A base plate is used to place strips of material to be cut. The cutting fixture described above is positioned above the strip of material to be cut; and A press having a pressure plate, the pressure plate being configured such that when a pad containing strip material and a cutting fixture is placed under the pressure plate, external pressure is applied to the operating plate of the cutting fixture to complete the cutting.

[0018] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. This utility model's cutting fixture has multiple cutting blades arranged at intervals on the bottom surface of the operating base plate, with the blades facing downwards. During the cutting process, when pressure is applied, multiple cutting blades can press down simultaneously, cutting multiple strips of material in parallel. For example, if the cutting fixture has ten cutting blades, and the spacing between adjacent blades matches the length of the strips to be cut, then a single pressing action can cut ten strips of material simultaneously. This batch processing method greatly increases the number of cuts per unit time, achieving an efficiency several times or even tens of times higher than traditional single-blade cutting. When facing large-scale production tasks, it can quickly provide a sufficient number of cut strips of material, effectively shortening the production cycle and reducing production costs.

[0019] 2. This utility model's cutting fixture effectively conceals and protects the cutting edge through an elastic buffer. In its first state, the elastic buffer completely encloses the cutting edge, preventing operators from directly contacting the sharp edge during daily operation, handling, and material preparation, thus fundamentally avoiding accidental cuts. When cutting is required, external pressure is applied to the operating platen of the cutting fixture by a press. Under this pressure, the elastic buffer compresses elastically, exposing the cutting edge and allowing it to cut into the strip of material. After cutting, the pressure is released, and the elastic buffer quickly springs back to its first state, concealing the cutting edge again. This dynamic edge concealment and exposure mechanism provides operators with comprehensive, end-to-end safety protection, significantly reducing operational risks and ensuring the personal safety of operators and the stability of the working environment.

[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0028] Example 1: Please see Figures 1 to 4 This utility model provides a cutting fixture 10 for strip materials. The cutting fixture 10 can cut strip materials efficiently, accurately and safely, and is especially suitable for cutting special strip materials such as fiber carrier sheets containing anticoagulants (such as lithium heparin). The cutting fixture 10 includes an operating base plate 11, multiple cutting blades 12, and an elastic buffer 13. The operating base plate 11 serves as the fundamental support structure of the entire cutting fixture 10, and its material selection significantly impacts the stability and service life of the cutting fixture. In this embodiment, the operating base plate 11 is formed from hardwood. Hardwood not only possesses good structural strength, providing a stable mounting surface for the cutting blade 12 and ensuring structural stability during the cutting process, but it is also easier to process and less expensive than materials such as metal. Furthermore, it is less likely to cause wear to the cutting blade 12 during installation. Of course, in other embodiments, the operating base plate 11 can be made of other suitable materials, such as hard plastic or metal sheets, as long as they meet the requirements for supporting and mounting the cutting blade 12. The cutting blade 12 is a straight blade made of high-strength alloy steel. This material has high hardness and wear resistance, ensuring that the cutting blade 12 remains sharp during long-term use and ensuring cutting effect. Multiple cutting blades 12 are spaced apart on the bottom surface of the operating base plate 11 with the blades facing downwards. This arrangement allows the blades to directly act on the strip material during the cutting process, improving cutting accuracy and efficiency. The spacing between adjacent blades arranged equidistantly in the transverse direction matches the length of the strip material to be cut and can be set according to actual cutting requirements. For example, when the strip material needs to be cut into 5cm long segments, the spacing between adjacent blades is set to 5cm. There are two implementation methods for the connection between the cutting blade 12 and the operating base plate 11 to adapt to different application scenarios. Firstly, the blade is integrally formed with the operating substrate 11 through an embedded curing process. Specifically, during the processing of the operating substrate 11, a groove matching the shape and size of the blade is pre-cut on the bottom surface of the operating substrate 11. The blade is then placed into the groove, and a specific curing agent is used to firmly bond the blade to the operating substrate 11, forming an integral structure. This connection method ensures high strength between the blade and the operating substrate 11, preventing blade loosening or displacement during cutting and guaranteeing cutting accuracy. Different cutting fixtures 10 can be configured with different blade spacings to accommodate different cutting requirements for strip materials. For example, a batch of cutting fixtures 10 with a blade spacing of 3cm can be produced, followed by another batch with a blade spacing of 6cm, etc. When cutting strip materials of different lengths, simply change the corresponding cutting fixture 10. Secondly, the operating base plate 11 is provided with standardized blade mounting positions, which include equidistant mounting slots. The spacing between adjacent mounting slots is an integer multiple of the minimum cutting unit. In this embodiment, the minimum cutting unit is set to 1cm, and the spacing between adjacent mounting slots is an integer multiple of 1cm, such as 1cm, 2cm, etc. By selecting different numbers of blades to install in different mounting positions, different cutting spacing combinations can be formed, thereby adapting to different cutting needs of strip materials. For example, when it is necessary to cut strip materials into 4cm long segments, blades can be installed in mounting slots with a spacing of 4cm; when it is necessary to cut into 7cm long segments, mounting slots with a spacing of 7cm can be selected. This installation method is highly flexible, eliminating the need to prepare multiple cutting fixtures 10 with different blade spacings. It only requires adjusting the installation position and number of blades according to needs, greatly reducing equipment costs. The elastic buffer 13 is an important component to ensure the safety of the cutting fixture 10 operation. It is configured to hide the cutting edge of the cutting blade 12 in the first state, and to be elastically compressed under external pressure in the second state to expose the cutting edge for cutting the placed strip material. It can also spring back to the first state after the external pressure is released. In order to enable the cutting blade 12 to pass smoothly through the elastic buffer body 13 to cut the strip material, the elastic buffer body 13 is provided with slits 131 for the cutting blade 12 to pass through. The number of slits 131 corresponds to the number of cutting blades 12, and the position also matches the installation position of the cutting blade 12. During the cutting process, the cutting blade 12 is forced to pass through the slits 131 by the extrusion fixture to cut the strip material. The choice of material for the elastic buffer 13 is also crucial. In this embodiment, the elastic buffer 13 can be made of sponge pad. Sponge pad has good elasticity and softness, can be easily compressed under pressure, and rebounds quickly after the pressure is released. At the same time, it is low in cost and readily available. Alternatively, the elastic buffer 13 can also include an upper sponge layer near the cutting edge 12 and a lower silicone layer located at the bottom of the upper sponge layer. The upper sponge layer has good cushioning performance, which can prevent the cutting edge 12 from encountering greater resistance when passing through the elastic buffer 13, and at the same time, it provides a certain degree of protection for the cutting edge of the cutting edge 12. The lower silicone layer has good elasticity and wear resistance, which can improve the service life of the elastic buffer 13, and at the same time, provide relatively stable support for strip materials during the cutting process. The thickness of the elastic buffer 13 is 1.1 to 1.3 times the protrusion height of the blade to ensure that the blade is completely hidden when not in operation and can penetrate smoothly under pressure. In this embodiment, the blade protrudes 1cm from the bottom surface of the operating plate 11, so the thickness of the elastic buffer 13 is chosen to be 1.2cm. In this way, when not in operation, the elastic buffer 13 can completely hide the blade edge, preventing the operator from accidentally touching the blade edge and causing injury. During the cutting process, when subjected to external pressure, the elastic buffer 13 can be compressed smoothly, exposing the blade edge for cutting. In this embodiment, the strip material is a fiber carrier sheet containing an anticoagulant, including lithium heparin. This type of fiber carrier sheet is widely used in the biomedical testing field and has high requirements for cutting precision and safety during the cutting process. The cutting fixture 10 of this invention can well meet these requirements. Example 2 This utility model embodiment also provides a cutting system, which includes a pad, a cutting fixture 10 as described in Embodiment 1, and a press. The cutting mat is used to place strips of material to be cut, providing a stable support surface for the cutting process. Made of rigid plastic, the mat has a smooth, flat surface that prevents scratches or damage to the strips during cutting. Furthermore, the size of the mat can be selected according to the length and quantity of the strips to be cut, ensuring it can accommodate a sufficient number of strips for batch cutting. The cutting fixture 10 is placed above the strip material to be cut. The fixture with the appropriate blade spacing can be selected according to the required length of the material, or the cutting spacing can be adjusted by changing the blade installation position. When placing the cutting fixture 10, it is necessary to ensure that the cutting blade 12 corresponds to the position to be cut on the strip material to ensure cutting accuracy. The press has a pressure plate, configured such that when a strip of material and a pad for the cutting fixture 10 are placed under the pressure plate, external pressure is applied to the operating base plate 11 of the cutting fixture 10 to complete the cutting. The press is hydraulically driven, providing stable and adjustable pressure. The operator can adjust the pressure applied by the press according to parameters such as the material and thickness of the strip material to ensure that the cutting operation is completed smoothly without damaging the strip material due to excessive pressure. Simultaneously, the press is equipped with safety protection devices, such as infrared sensors. When the operator's hand or other body parts enter the danger zone, the press will immediately stop working, further ensuring the operator's personal safety. The following section, using the aforementioned cutting fixture 10 and cutting system, details the specific process of its cutting operation: First, the operator selects a suitable cutting fixture 10 based on the required length of the strip material to be cut. If the cutting fixture 10 is an integral part of the blade and the operating base plate 11, the operator directly selects a fixture whose blade spacing matches the length to be cut. If the cutting fixture 10 with adjustable blade mounting position is used, the operator installs the blade in the corresponding mounting slot according to the requirements, ensuring that the spacing between adjacent blades meets the requirements. Next, neatly place the strips of material to be cut on the mat. During placement, ensure that one end of each strip is aligned to avoid misalignment and ensure consistent length of each segment after cutting. Simultaneously, based on the number of cutting blades 12 on the cutting fixture 10, rationally arrange the number of strips to be placed. Generally, the number of strips placed corresponds to the number of cutting blades 12 to achieve batch cutting. Then, the cutting fixture 10 is placed above the strip material, so that the cutting blade 12 corresponds to the position to be cut on the material, while ensuring that the slit 131 on the elastic buffer 13 is aligned with the position of the cutting blade 12 so that the cutting blade 12 can pass smoothly through the slit 131. Next, place the pad containing the strip material and the cutting fixture 10 under the press plate of the press, and adjust the position of the pad so that the operating plate 11 of the cutting fixture 10 is directly below the press plate. The press is started, and the press plate moves downward under hydraulic drive, applying external pressure to the operating plate 11 of the cutting fixture 10. Under the pressure, the elastic buffer 13 begins to compress elastically, and its thickness gradually decreases. The cutting edge of the cutting blade 12, which was originally hidden inside the elastic buffer 13, is gradually exposed and passes through the slit 131 to contact the strip-shaped material. As the pressure continues to increase, the cutting edge of the cutting blade 12 cuts into the strip-shaped material, completing the cutting operation. After cutting is completed, the press is turned off, and the press plate moves upward, releasing the pressure on the operating base plate 11. At this time, the elastic buffer 13 quickly rebounds to the first state under its own elastic force, hiding the cutting edge of the cutting blade 12 again. Finally, the operator removes the cut strips of material from the mat, completing the entire cutting process. In practical applications, if it is necessary to cut strip materials of different lengths, for the cutting fixture 10 with the blade and the operating base plate 11 integrally formed, it is only necessary to replace the fixture with the corresponding blade spacing; for the cutting fixture 10 with adjustable blade installation position, the installation position and number of blades are adjusted, making the operation simple and convenient.

[0029] In summary, the cutting fixture and system for strip materials of this invention, through reasonable structural design, effectively overcomes the defects of low efficiency, poor operational safety, and insufficient adaptability in the cutting of strip materials in the prior art. It has high practical value and promotion significance, and can play an important role in multiple fields such as industrial production and biomedical testing.
