[0016] The beneficial effects of the present invention are: Compared with the existing preparation of ultra-high molecular weight polyethylene stab and cut resistant materials, the present invention realizes a high degree of integration and automation from raw material input to finished product output through carefully designed functional modules. From the wool mixing mechanism to the material receiving mechanism, each step is closely connected to form an efficient and smooth production line. This design not only improves production efficiency, but also reduces manual intervention and reduces production costs. At the same time, the automated production process helps to maintain the stability and consistency of the production process, thereby ensuring the quality and performance of the final product. In the wool mixing mechanism, the fiber material is mixed and combed, which effectively improves the uniformity of the fiber. This process is crucial for subsequent processing because it can ensure the uniform distribution of the fiber in subsequent steps, thereby improving the overall performance of the material. In addition, the wool mixing mechanism also transports the mixed and combed fiber material toward the cotton mixing mechanism, realizing the continuous supply of raw materials and providing convenience for subsequent mixing and storage.

[0017] The mixing mechanism further mixes and stores the fiber materials, ensuring the diversity and uniformity of the raw materials. Through the processing of the mixing mechanism, the fiber materials are fully mixed to form a fiber mixture with excellent performance. This mixture is further loosened and separated in the subsequent opening mechanism, making it a relatively fluffy and dispersed fiber state. Fibers in this state are easier to be processed by subsequent equipment and help improve the puncture and cut resistance of the final product. The pneumatic cotton box mechanism plays an important role in storing and transporting fiber materials in this system. By adjusting the internal air pressure, the pneumatic cotton box mechanism can accurately control the output and speed of the fiber material. This precise control is essential to maintain the stability and continuity of the production process. At the same time, the pneumatic cotton box mechanism can also flexibly adjust the output according to production needs, so as to meet the production of products with different specifications and performance requirements. The setting of the belt scale enables the system to continuously weigh and measure the bulk materials placed on the conveyor belt. This function not only helps to accurately control the input amount of raw materials, but also can promptly detect abnormal conditions in the production process, thereby ensuring the stability and reliability of the production process.

[0018] The combing mechanism is used to receive the fiber material delivered by the belt scale and further comb it. The combed fiber material is more uniform and delicate, providing a good foundation for the subsequent pre-puncture and pricking steps. The efficient work of the combing mechanism not only improves production efficiency, but also helps to improve the puncture and cut resistance of the final product. The roller pre-puncture mechanism and the high-speed pre-puncture mechanism jointly pre-puncture the fiber material. Through the rolling of the pressure roller and the puncture and pressure of the high-speed pre-puncture mechanism, the fibers of the fiber material are staggered and connected together to form a tighter and stronger structure. This structure helps to improve the strength and toughness of the material, thereby enhancing its puncture and cut resistance. After being processed by the high-speed pre-puncture mechanism, the fiber material is sent to the puncture mechanism for multiple punctures. This step further consolidates the connection between the fibers, so that the final product has more outstanding puncture and cut resistance. At the same time, multiple punctures also help to improve the wear resistance and durability of the material, so that it can maintain stable performance in various harsh environments.

[0019] The invention realizes an efficient, stable and reliable production process through highly integrated, refined processing flow and optimized material performance improvement. The successful application of this system not only helps to improve production efficiency and quality level, but also helps to promote scientific and technological progress and development in the field of stab and cut resistant materials.

The belt scale 6 is arranged on one side of the air pressure cotton box mechanism 5, and is used to receive the fiber material output by the air pressure cotton box, so as to continuously weigh and measure the bulk material placed on the conveyor belt; the combing mechanism 7 is used to receive the fiber material delivered by the belt scale 6, and is used for combing the fiber material. After combing, the fiber material is transported toward the roller pre-puncturing mechanism 10, and the roller pre-puncturing mechanism 10 is used to roll and pre-puncture the fiber material. The fiber material is first rolled by a pressure roller and then sent to the high-speed pre-puncturing mechanism 20 for high-speed pre-puncturing, so that the rolled fiber material is punctured and pressed, so that the fibers of the fiber material are staggered; after passing through the high-speed pre-puncturing mechanism 20, it is sent to the puncturing mechanism 8 for multiple puncturing, and finally the material is collected by the material receiving mechanism 9. This embodiment realizes a high degree of integration and automation from raw material input to finished product output through the carefully designed functional modules. From the wool mixing mechanism 1 to the material receiving mechanism 9, each step is closely connected to form an efficient and smooth production line. This design not only improves production efficiency, but also reduces manual intervention and reduces production costs. At the same time, the automated production process helps maintain the stability and consistency of the production process, thereby ensuring the quality and performance of the final product. In the wool mixing mechanism 1, the fiber material is mixed and combed, which effectively improves the uniformity of the fiber. This process is crucial for subsequent processing because it ensures the uniform distribution of the fiber in subsequent steps, thereby improving the overall performance of the material. In addition, the wool mixing mechanism 1 also transports the mixed and combed fiber material toward the cotton mixing mechanism 2, realizing the continuous supply of raw materials and facilitating the subsequent mixing and storage.

[0025] In this embodiment, the cotton mixing mechanism 2 further mixes and stores the fiber materials to ensure the diversity and uniformity of the raw materials. Through the processing of the cotton mixing mechanism 2, the fiber materials are fully mixed to form a fiber mixture with excellent performance. This mixture is further loosened and separated in the subsequent opening mechanism 3, making it a relatively fluffy and dispersed fiber state. Fibers in this state are easier to be processed by subsequent equipment and help to improve the puncture and cut resistance of the final product. The pneumatic cotton box mechanism 5 plays an important role in storing and transporting fiber materials in the system. By adjusting the internal air pressure, the pneumatic cotton box mechanism 5 can accurately control the output and speed of the fiber material. This precise control is crucial to maintaining the stability and continuity of the production process. At the same time, the pneumatic cotton box mechanism 5 can also flexibly adjust the output according to production needs, thereby meeting the production of products with different specifications and performance requirements. The setting of the belt scale 6 enables the system to continuously weigh and measure the bulk materials placed on the conveyor belt. This function not only helps to accurately control the input amount of raw materials, but also can promptly detect abnormal conditions in the production process, thereby ensuring the stability and reliability of the production process.

[0026] In this embodiment, the combing mechanism 7 is used to receive the fiber material conveyed by the belt scale 6 and further comb it. The fiber material after combing is more uniform and delicate, which provides a good foundation for the subsequent pre-puncture and pricking steps. The efficient operation of the combing mechanism 7 not only improves the production efficiency, but also helps to improve the anti-puncture and anti-cutting performance of the final product. The roller pre-puncture mechanism 10 and the high-speed pre-puncture mechanism 20 jointly perform pre-puncture treatment on the fiber material. Through the rolling of the pressure roller and the puncture and pressure of the high-speed pre-puncture mechanism 20, the fibers of the fiber material are staggered and connected together to form a tighter and stronger structure. This structure helps to improve the strength and toughness of the material, thereby enhancing its anti-puncture and anti-cutting performance. After being processed by the high-speed pre-puncture mechanism 20, the fiber material is sent to the puncture mechanism 8 for multiple punctures. This step further consolidates the connection between the fibers, so that the final product has more outstanding anti-puncture and anti-cutting performance. At the same time, multiple punctures also help to improve the wear resistance and durability of the material, so that it can maintain stable performance in various harsh environments.

[0028] See also Figure 3As shown, the wool mixing mechanism 1 includes a wool mixing frame 11, a wool mixing box 12, a wool mixing roller group 13 and a wool mixing conveying line 14, wherein the wool mixing box 12 is arranged on the wool mixing frame, and the wool mixing roller group 13 is arranged in the wool mixing box 12, and the wool mixing roller group 13 is used to mix the fiber material in the wool mixing box 12, and then transport it toward the wool mixing conveying line 14, and the wool mixing conveying line 14 is used to transport the fiber material toward the cotton mixing mechanism 2. In this embodiment, the wool mixing box 12 is arranged on the wool mixing frame, which provides a stable and closed wool mixing environment for the ultra-high molecular weight polyethylene fiber material. This environment is conducive to the uniform mixing of fibers, reduces the entanglement and knotting between fibers, and provides high-quality fiber raw materials for subsequent processing. Secondly, the arrangement of the wool mixing roller group 13 in the wool mixing box 12 realizes the effective combing and wool mixing of the fiber material through precise mechanical design and power transmission. This process not only improves the parallelism and dispersion of the fibers, but also enhances the bonding force between the fibers, laying a solid foundation for the preparation of materials with excellent puncture and cut resistance. In addition, the introduction of the wool conveying line 14 realizes the automatic conveying of fiber materials from the wool box 12 to the cotton blending mechanism 2. This not only improves production efficiency, but also reduces errors and pollution caused by manual operation, ensuring the continuity and stability of the entire preparation process.

In this embodiment, the mixing mechanism 2 effectively achieves uniform mixing of fiber raw materials in the mixing box 21 through its built-in mixing roller group 22, ensuring the uniformity of raw materials in the subsequent processing process. This uniform mixing is crucial to improving the overall performance of puncture-proof and cut-proof materials, and can avoid material performance differences caused by uneven distribution of raw materials. At the same time, the opening mechanism 3 connected to the cotton mixing mechanism 2 fully opens the raw materials in the opening box 33 through its precisely designed opening roller group 34. The opening feeding component 32 ensures that the raw materials enter in an orderly manner, while the opening output component 35 efficiently outputs the processed fibers to the transmission mechanism 4 to prepare for the next processing. This series of operations not only improves the opening degree of the raw materials, but also significantly enhances the interweaving and bonding force between the fibers, laying a solid foundation for the preparation of high-strength, high-toughness puncture-proof and cut-proof materials.

In this embodiment, the cotton box feeding module 51 ensures that the raw materials can enter the cotton box body 52 stably and continuously, providing a solid foundation for the subsequent fiber material processing. The precise control of this step is crucial to ensure the uniformity and consistency of the final product. Secondly, the air pressure control module inside the cotton box body 52 plays a key role. By finely adjusting the internal air pressure, the module can accurately control the output and speed of the fiber material, thereby ensuring that the dispersion and mixing of the fibers reach the optimal state during the preparation process of the ultra-high molecular weight polyethylene material. This precise control helps to improve the overall performance and quality of the material. Finally, the close connection between the cotton box discharge module 53 and the belt scale 6 realizes the precise measurement and control of the fiber material delivery. This not only improves production efficiency, but also ensures that the input ratio of raw materials is accurate, providing a strong guarantee for the preparation of high-performance puncture-proof and cut-proof materials. In the preparation process of ultra-high molecular weight polyethylene puncture-proof and cut-proof materials, the pneumatic cotton box significantly improves the quality and production efficiency of the product through its precise raw material input, internal air pressure control and material output functions. See also Figure 7As shown, the combing mechanism 7 includes a combing feed guide roller group 71, a transverse combing roller group 72 and a longitudinal combing roller group 73. The combing feed guide roller group 71 is used to convey the fiber material on the belt scale 6 toward the transverse combing roller group 72. The longitudinal combing roller group 73 is arranged at the rear side of the transverse combing roller group 72 to comb the combed fiber material and convey the combed fiber material to the roller pre-puncturing mechanism 10. In this embodiment, the combing feed guide roller group 71 can accurately guide the fiber material on the belt scale 6 to the transverse combing roller group 72. This process ensures the orderly arrangement and uniform distribution of the fiber material, laying a solid foundation for subsequent combing work. The transverse combing roller group 72 further refines the fiber material through its unique combing method, so that the interweaving between the fibers is tighter, thereby enhancing the overall strength of the material. The longitudinal combing roller group 73 is arranged at the rear side of the transverse combing roller group 72. Its main function is to deeply comb the fiber material that has been preliminarily combed to further improve the arrangement state of the fibers. Through this step, the orientation and uniformity of the fiber material are significantly improved, which is crucial for preparing ultra-high molecular weight polyethylene materials with excellent puncture and cut resistance. Finally, the fiber material processed by the combing mechanism 7 is transported to the roller pre-puncture mechanism 10, providing high-quality raw materials for subsequent needle punching reinforcement and other process steps. Therefore, the combing mechanism 7 not only improves the production efficiency in the preparation process of ultra-high molecular weight polyethylene puncture and cut resistance materials.

[0031] See also Fig.11 As shown, the roller pre-puncture mechanism 10 includes a roller pre-puncture frame 101, a roller pre-puncture pressing roller 102 and a roller pre-puncture conveying assembly 103, wherein the roller pre-puncture pressing roller 102 is evenly provided with through holes, and the roller pre-puncture pressing roller 102 is used for pre-puncturing and compacting the combed fiber material, and the through holes are used for exhausting during the rolling process, and the roller pre-puncture conveying assembly 103 is used for conveying the compacted material toward the high-speed pre-puncture mechanism 20. In this embodiment, the uniformly distributed through-hole design on the roller pre-puncture pressing roller 102 not only enhances the exhaust capacity of the pressing roller during the rolling process, avoids the problem of uneven compaction caused by gas retention, but also ensures that the fiber material can fully discharge the internal air while being subjected to uniform pressure, forming a more compact and solid structure. This feature is crucial for improving the overall strength and wear resistance of the puncture-proof and cut-proof material. In addition, the introduction of the roller pre-puncture conveying assembly 103 enables the compacted material to be stably and efficiently conveyed toward the high-speed pre-puncture mechanism 20. The optimization of this process not only improves production efficiency, but also ensures the consistency and stability of subsequent processing links, providing a strong guarantee for the quality control of the final product.

[0032] The high-speed pre-puncture mechanism 20 includes a high-speed pre-puncture frame 201, a high-speed pre-puncture drive module 202 and a high-speed pre-puncture needle plate 203, wherein the high-speed pre-puncture drive module 202 is arranged on the high-speed pre-puncture frame 201, and the high-speed pre-puncture drive module 202 and the high-speed pre-puncture needle plate 203 are both provided with two groups, and are used for acupuncture compaction of the upper and lower surfaces of the compacted material. In the present embodiment, the high-speed pre-puncture frame 201 is used as a stable support platform to ensure the stability and accuracy of the entire acupuncture process. The high-speed pre-puncture drive module 202 arranged thereon, as a power source, can provide a continuous and efficient driving force, so that the acupuncture action can be completed quickly and accurately. More importantly, the drive module and the high-speed pre-puncture needle plate 203 are both designed as a double-group configuration, and this innovative design enables the mechanism to simultaneously acupuncture compaction of the upper and lower surfaces of the compacted ultra-high molecular weight polyethylene material, greatly improving production efficiency. In actual operation, the use of the high-speed pre-puncture mechanism 20 not only enhances the fiber interlacing density of the material, but also significantly improves the overall strength and toughness of the material.

[0033] See also Figure 8As shown, the piercing mechanism 8 includes a piercing conveying line 81, a first piercing component 82 and a second piercing component 83, wherein the first piercing component 82 and the second piercing component 83 are sequentially arranged on the piercing conveying line 81; the piercing conveying line 81 is used for clamping and conveying the edge of the compacted material, and the first piercing component 82 is used for piercing the upper surface of the material on the piercing conveying line 81; the second piercing component 83 is used for piercing the lower surface of the material on the piercing conveying line 81 that has been pierced on the upper surface, so as to make the fibers of two adjacent layers of materials excessively connected. Specifically, the piercing conveyor line 81 includes two groups of conveying clamping modules 811 arranged opposite to each other, and the conveying clamping modules 811 are arranged in two groups opposite to each other up and down to clamp and convey the compacted material; the first piercing assembly 82 includes a first support platform 821, a first needle plate 822 and a first piercing drive module 823, the first support platform 821 is provided with a first support drive module 824, the first support drive module 824 is used to drive the first support platform 821, so that the upper surface of the first support platform 821 supports the lower surface of the material; a plurality of first piercing needles 8221 are evenly distributed on the first needle plate 822, and the first piercing drive module 823 is used to drive the first support platform 821 ... The first needle plate 822 is used to drive the first piercing needle 8221 to pierce the surface of the material; the second piercing assembly 83 includes a second support platform 831, a second needle plate 832 and a second piercing drive module 833, the second support platform 831 is provided with a second support drive module 834, the second support drive module 834 is used to drive the second support platform 831, so that the lower surface of the second support platform 831 is in contact with the upper surface of the material; a plurality of second piercing needles 8321 are evenly distributed on the second needle plate 832, and the second piercing drive module 833 is used to drive the second needle plate 832 to drive the second piercing needle 8321 to pierce the bottom surface of the material. In this embodiment, the piercing mechanism 8 realizes the precise clamping and stable conveying of the edge of the compacted material through the design of the piercing conveying line 81. In the preparation process of ultra-high molecular weight polyethylene materials, the uniformity and stability of the compacted material are crucial. The two groups of relatively arranged conveying clamping modules 811 of the piercing conveyor line 81 work together up and down to ensure that the material will not deviate or loosen during the conveying process, providing a solid foundation for the subsequent piercing operation. This feature is of great significance for ensuring the dimensional accuracy and uniformity of ultra-high molecular weight polyethylene puncture-proof and cut-proof materials during the processing process. Secondly, the sequential arrangement of the first piercing component 82 and the second piercing component 83 realizes comprehensive piercing treatment of the upper and lower surfaces of the material. The first piercing component 82 utilizes the design of the first support platform 821 and the first needle plate 822, and is driven by the first piercing drive module 823, so that the first piercing needle 8221 can penetrate into the upper surface of the material to form an effective fiber connection point. This step not only enhances the degree of fiber interweaving on the surface of the material, but also improves the overall strength of the material.Subsequently, the second piercing assembly 83, under the action of the second support platform 831 and the second needle plate 832, pierces the lower surface of the material, further promoting the over-connection of the fibers of the adjacent two layers of the material. This double piercing treatment of the upper and lower surfaces significantly improves the interlayer bonding force and overall piercing and cutting resistance of the ultra-high molecular weight polyethylene piercing and cutting resistant material. Furthermore, the design of the piercing mechanism 8 fully considers the support and fitting requirements of the material. The first support platform 821 and the second support platform 831 are driven by the first support drive module 824 and the second support drive module 834 respectively, and the support position can be adjusted according to the actual situation of the material to ensure that the material is fully supported and fitted during the piercing process. This flexible and adjustable support method not only improves the accuracy and efficiency of piercing, but also effectively avoids the problem of uneven piercing caused by material deformation. Finally, the piercing mechanism 8 can significantly improve the piercing and cutting resistance level of the material in the preparation process of the ultra-high molecular weight polyethylene piercing and cutting resistant material. Through the fine piercing treatment, the fiber structure inside the material is effectively strengthened and reorganized, forming a tighter and stronger fiber network. This structural optimization enables the ultra-high molecular weight polyethylene stab and cut resistant material to better disperse and absorb energy when facing the impact of sharp objects, thereby significantly improving its stab and cut resistant performance.

[0034] See also Figures 9 and 10As shown, it also includes a trimming mechanism 30 and a detection mechanism 40. The second piercing assembly 83 conveys the pierced material toward the trimming mechanism 30. The trimming mechanism 30 includes a pressing module 301, a rotating module 302 and an edge cutting module 303. The pressing module 301 is used to press and fix the material after secondary compaction. The edge cutting module 303 is used to trim the edge of the pressing module 301. The rotating module 302 is used to drive the pressing module 301 to rotate so as to adjust the edges in different directions for trimming. The pressing module 301 includes a pressing platform 3011 and a pressing drive module 3012. The pressing drive module 3012 is provided with a pressing plate 3013. The rotating module 302 is used to drive the pressing platform 3011 to rotate. The edge cutting module 303 includes a trimming drive module 3031 and a trimming tool 3032. The trimming tool 3032 is used to trim the edge of the material. Specifically, the detection mechanism 40 includes a detection conveying component 401, a laser thickness measuring element 402 and a weight detection component 403. The detection conveying component 401 is used to receive the material after trimming by the trimming mechanism 30 for conveying; the detection conveying component 401 is provided with a detection box 404, the laser thickness measuring element 402 is arranged in the detection box 404 to measure the thickness of the material, and the weight detection component 403 is arranged on the detection conveying component 401 and is used to detect the weight of the material; a detection material picking component 4011 is arranged on one side of the detection conveying component 401, and the detection material picking component 4011 is used to grab the material on the trimming mechanism 30 and place it on the detection conveying component 401. After the detection is completed, the detection conveying component 401 conveys the material to the receiving mechanism 9 for receiving. In this embodiment, the trimming mechanism 30 realizes the precise trimming of the edge of the material after secondary compaction through the synergistic effect of the pressing module 301, the rotating module 302 and the edge cutting module 303. The clamping module 301 ensures that the material remains stable during the trimming process, and the rotating module 302 flexibly adjusts the direction of the material, so that the edge cutting module 303 can trim the edge of the material comprehensively and evenly, thereby effectively improving the appearance quality and dimensional accuracy of the material. Secondly, the detection mechanism 40 realizes multi-dimensional detection of the trimmed material through the comprehensive use of the detection conveying component 401, the laser thickness measuring element 402 and the weight detection component 403. The laser thickness measuring element 402 can accurately measure the thickness of the material to ensure that the material meets the specific anti-puncture and anti-cutting performance requirements; the weight detection component 403 is used to verify whether the weight of the material meets the standard, further ensuring the consistency and reliability of the material. In addition, the introduction of the detection and material collection component 4011 realizes the efficient and automatic transfer of materials from the trimming mechanism 30 to the detection and conveying component 401, avoiding the errors and safety hazards that may be caused by manual operation. At the same time, after completing the detection, the detection and conveying component 401 can automatically convey the material to the receiving mechanism 9 for receiving the material, thereby improving the automation and production efficiency of the entire preparation process.
