[0017] The beneficial effects of the present invention are:

[0018] Compared with the preparation of existing ultra-high molecular weight polyethylene stab-resistant and cut-resistant materials, through each carefully designed functional module, the present invention realizes the highly integrated and automated process from raw material input to finished product output. From the wool mixing mechanism to the material receiving mechanism, each step is closely connected, forming an efficient and smooth production line. This design not only improves production efficiency but also reduces manual intervention and production costs. At the same time, the automated production process helps to maintain the stability and consistency of the production process, thus ensuring the quality and performance of the final product. In the wool mixing mechanism, the fiber materials are mixed and carded, effectively improving the uniformity of the fibers. This process is crucial for subsequent processing because it can ensure the uniform distribution of fibers in subsequent steps, thereby improving the overall performance of the material. In addition, the wool mixing mechanism transports the fiber materials after mixing and carding towards the cotton blending mechanism, realizing the continuous supply of raw materials and facilitating subsequent mixing and storage.

[0019] The cotton blending mechanism further mixes and stores the fiber materials, ensuring the diversity and uniformity of the raw materials. Through the treatment of the cotton blending mechanism, the fiber materials are fully mixed to form a fiber mixture with excellent properties. This mixture is further loosened and separated in the subsequent opening mechanism, making it into a more fluffy and dispersed fiber state. Fibers in this state are easier to be processed by subsequent equipment and contribute to improving the stab-resistant and cut-resistant performance 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 volume and speed of fiber materials. This precise control is crucial for maintaining the stability and continuity of the production process. At the same time, the pneumatic cotton box mechanism can also flexibly adjust the output volume 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 this 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 timely detect abnormal situations in the production process, thereby ensuring the stability and reliability of the production process.

[0020] The carding mechanism is used to receive the fibrous material conveyed by the belt scale and further card it. After carding, the fibrous material is more uniform and delicate, providing a good foundation for the subsequent pre-piercing and stabbing steps. The efficient operation of the carding mechanism not only improves production efficiency but also helps to enhance the puncture and cut resistance performance of the final product. The roller pre-piercing mechanism and the high-speed pre-piercing mechanism jointly perform pre-piercing treatment on the fibrous material. Through the roller pressing of the pressure roller and the stabbing pressure of the high-speed pre-piercing mechanism, the fibers of the fibrous material are interlaced and connected together, forming a more compact and firm structure. This structure helps to improve the strength and toughness of the material, thereby enhancing its puncture and cut resistance performance. After being processed by the high-speed pre-piercing mechanism, the fibrous material is sent to the stabbing mechanism for multiple stabbings. This step further consolidates the connection between the fibers, making the final product have more excellent puncture and cut resistance performance. At the same time, multiple stabbings also help to improve the wear resistance and durability of the material, enabling it to maintain stable performance in various harsh environments.

[0021] Through the technical effects in multiple aspects such as highly integrated and refined processing processes and optimized improvement of material properties, the present invention realizes an efficient, stable, and reliable production process. The successful application of this system not only helps to improve production efficiency and quality levels but also contributes to the scientific and technological progress and development in the field of puncture and cut resistant materials.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0037] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As Figures 1 to 11As shown, in one embodiment of the present invention, a system for preparing ultra-high molecular weight polyethylene stab-proof and cut-proof materials is involved, comprising a wool mixing mechanism 1, a cotton blending mechanism 2, a loosening mechanism 3, a transmission mechanism 4, a pneumatic cotton box mechanism 5, a belt scale 6, a combing mechanism 7, a roller pre-puncturing mechanism 10, a high-speed pre-puncturing mechanism 20, a pricking mechanism 8 and a material receiving mechanism 9 which are connected in sequence, wherein the wool mixing mechanism 1 is used for mixing and combing fiber materials to improve the uniformity of the fibers, the wool mixing mechanism 1 is used for transporting the mixed and combed fiber materials toward the cotton blending mechanism 2, the cotton blending mechanism 2 is used for mixing and storing the fiber materials, and transporting the mixed fiber materials to the loosening mechanism 3 for transportation, the loosening mechanism 3 is used for loosening and separating the fiber materials to make them into a relatively fluffy and dispersed fiber state, and then transmitting them to the pneumatic cotton box mechanism 5 through the transmission mechanism 4, the pneumatic cotton box mechanism 5 is used for storing and transporting the fiber materials, and controlling the output and speed of the fiber materials by adjusting the internal air pressure. 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.

[0039] 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.

[0040] 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.

[0041] In this embodiment, through the technical effects of high integration, refined processing flow and optimized material performance improvement, an efficient, stable and reliable production process is achieved. 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.

[0042] See also Figure 3As shown in the figure, 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 conveyor line 14. The wool mixing box 12 is arranged on the wool mixing frame, the wool mixing roller group 13 is arranged in the wool mixing box 12, the wool mixing roller group 13 is used to mix the fiber materials in the wool mixing box 12, and then convey them towards the wool mixing conveyor line 14. The wool mixing conveyor line 14 is used to convey the fiber materials towards the cotton mixing mechanism 2. In this embodiment, the wool mixing box 12 is arranged on the wool mixing frame, providing a stable and enclosed wool mixing environment for ultra-high molecular weight polyethylene fiber materials. This environment helps to evenly mix the fibers, reduce entanglement and knotting between the fibers, and provide 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 effective combing and wool mixing of the fiber materials through precise mechanical design and power transmission. This process not only improves the parallelism and dispersibility of the fibers, but also enhances the bonding force between the fibers, laying a solid foundation for preparing materials with excellent puncture and cut resistance performance. In addition, the introduction of the wool mixing conveyor line 14 realizes the automatic conveyance of the fiber materials from the wool mixing box 12 to the cotton mixing 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.

[0043] Refer to Figures 4 to 5 As shown in the figure, the cotton mixing mechanism 2 includes a cotton mixing box 21 and a cotton mixing roller group 22 arranged in the cotton mixing box 21. The cotton mixing roller group 22 is arranged in the cotton mixing box 21, and one end of the cotton mixing box 21 is connected to the loosening mechanism 3. The loosening mechanism 3 includes a loosening frame 31, a loosening feeding component 32, a loosening box body 33, a loosening roller group 34, and a loosening output component 35. One end of the loosening output component 35 is connected to the transmission mechanism 4. The loosening feeding component 32, the loosening box body 33, and the loosening output component 35 are sequentially arranged on the loosening frame 31, and the loosening roller group 34 is arranged in the loosening box body 33. In this embodiment, the cotton mixing mechanism 2 effectively realizes the uniform mixing of the fiber raw materials in the cotton mixing box 21 through its built-in cotton mixing roller group 22, ensuring the uniformity of the raw materials in the subsequent processing process. This uniform mixing is crucial for improving the overall performance of the puncture and cut resistant materials, and can avoid material performance differences caused by uneven raw material distribution. At the same time, the loosening mechanism 3 connected to the cotton mixing mechanism 2 fully loosens the raw materials in the loosening box body 33 through its precisely designed loosening roller group 34. The loosening feeding component 32 ensures the orderly entry of the raw materials, while the loosening output component 35 efficiently outputs the processed fibers to the transmission mechanism 4 to prepare for the next step of processing. This series of operations not only improves the loosening degree of the raw materials, but also significantly enhances the interweaving and bonding force between the fibers, laying a solid foundation for preparing high-strength and high-toughness puncture and cut resistant materials.

[0044] Refer to Figure 6As shown, the pneumatic bale feeder mechanism 5 includes a bale feeder module 51, a bale body 52, and a bale discharge module 53. The bale feeder module 51 is used to feed the bale body 52, and the bale discharge module 53 is used to connect to the belt scale 6 and convey the fiber material towards the belt scale 6. A pneumatic control module for adjusting the internal air pressure to control the output volume and speed of the fiber material is provided inside the bale body 52. In this embodiment, the bale feeder module 51 ensures that the raw materials can enter the bale body 52 stably and continuously, providing a solid foundation for the subsequent fiber material processing. The precise control of this step is crucial for ensuring the uniformity and consistency of the final product. Secondly, the pneumatic control module inside the bale body 52 plays a key role. By finely adjusting the internal air pressure, this module can precisely control the output volume and speed of the fiber material, thus ensuring that during the preparation process of ultra-high molecular weight polyethylene materials, the dispersion and mixing of the fibers reach the optimal state. This precise control helps to improve the overall performance and quality of the material. Finally, the close connection between the bale discharge module 53 and the belt scale 6 enables precise metering and control of the fiber material conveyance. This not only improves production efficiency but also ensures that the input ratio of the raw materials is accurate, providing a strong guarantee for the preparation of high-performance stab-resistant and cut-resistant materials. During the preparation process of ultra-high molecular weight polyethylene stab-resistant and cut-resistant materials, the pneumatic bale feeder significantly improves the product quality and production efficiency through its precise raw material input, internal air pressure control, and material output functions

[0045] Refer to Figure 7As shown in the figure, the carding mechanism 7 includes a carding feeding guide roller group 71, a transverse carding roller group 72, and a longitudinal carding roller group 73. The carding feeding guide roller group 71 is used to convey the fiber material on the belt scale 6 towards the transverse carding roller group 72. The longitudinal carding roller group 73 is arranged behind the transverse carding roller group 72 to card the carded fiber material and convey the carded fiber material to the roller pre-punching mechanism 10. In this embodiment, the carding feeding guide roller group 71 can accurately guide the fiber material on the belt scale 6 to the transverse carding roller group 72. This process ensures the orderly arrangement and uniform distribution of the fiber material, laying a solid foundation for the subsequent carding work. The transverse carding roller group 72 further refines the fiber material through its unique carding method, making the interweaving between fibers closer, thereby enhancing the overall strength of the material. The longitudinal carding roller group 73 is arranged behind the transverse carding roller group 72, and its main function is to deeply card the fiber material that has been preliminarily carded 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 stab and cut resistance performance. Finally, the fiber material processed by the carding mechanism 7 is conveyed to the roller pre-punching mechanism 10, providing high-quality raw materials for subsequent process steps such as needle punching reinforcement. Therefore, the carding mechanism 7 not only improves the production efficiency in the preparation process of ultra-high molecular weight polyethylene stab and cut resistant materials.

[0046] Refer to Figure 11 As shown in the figure, the roller pre-punching mechanism 10 includes a roller pre-punching machine frame 101, a roller pre-punching pressure roller 102, and a roller pre-punching conveying component 103. The roller pre-punching pressure roller 102 is evenly distributed with through holes. The roller pre-punching pressure roller 102 is used to pre-punch and compact the carded fiber material. The through holes are used for exhausting air during the roller pressing process. The roller pre-punching conveying component 103 is used to convey the compacted material towards the high-speed pre-punching mechanism 20. In this embodiment, the design of the evenly distributed through holes on the roller pre-punching pressure roller 102 not only enhances the air exhaust capacity of the pressure roller during the roller pressing process, avoiding the problem of uneven compaction caused by gas retention, but also ensures that while the fiber material is under uniform pressure, the internal air can be fully discharged, forming a more compact and solid structure. This characteristic is crucial for improving the overall strength and wear resistance of the stab and cut resistant material. In addition, the introduction of the roller pre-punching conveying component 103 enables the compacted material to be stably and efficiently conveyed towards the high-speed pre-punching mechanism 20. The optimization of this process not only improves the production efficiency but also ensures the consistency and stability of the subsequent processing links, providing a strong guarantee for the quality control of the final product.

[0047] The high-speed pre-punching mechanism 20 includes a high-speed pre-punching machine frame 201, a high-speed pre-punching drive module 202, and a high-speed pre-punching needle plate 203. The high-speed pre-punching drive module 202 is arranged on the high-speed pre-punching machine frame 201. There are two groups each of the high-speed pre-punching drive module 202 and the high-speed pre-punching needle plate 203, and they are used for needle punching and compacting the upper and lower surfaces of the compacted material. In this embodiment, the high-speed pre-punching machine frame 201 serves as a stable support platform, ensuring the stability and accuracy of the entire needle punching process. The high-speed pre-punching drive module 202 arranged thereon, as a power source, can provide continuous and efficient driving force, enabling the needle punching action to be completed quickly and precisely. Particularly importantly, both the drive module and the high-speed pre-punching needle plate 203 are designed in a double-group configuration. This innovative design enables the mechanism to simultaneously perform needle punching and compacting on the upper and lower surfaces of the compacted ultra-high molecular weight polyethylene material, greatly improving the production efficiency. In actual operation, the application of the high-speed pre-punching mechanism 20 not only enhances the fiber interweaving density of the material but also significantly improves the overall strength and toughness of the material. The ultra-high molecular weight polyethylene material processed by this mechanism performs excellently in terms of anti-puncture and anti-cutting properties and can effectively resist the puncture and cutting of sharp objects, thus meeting the requirements for high-performance protective materials in specific fields.

[0048] Refer to Figure 8As shown, the thorn pricking mechanism 8 includes a thorn pricking conveyor line 81, a first thorn pricking assembly 82, and a second thorn pricking assembly 83. The first thorn pricking assembly 82 and the second thorn pricking assembly 83 are sequentially arranged on the thorn pricking conveyor line 81. The thorn pricking conveyor line 81 is used for clamping and conveying the edge of the compacted material. The first thorn pricking assembly 82 is used for pricking the upper surface of the material on the thorn pricking conveyor line 81. The second thorn pricking assembly 83 is used for pricking the lower surface of the material that has been pricked on the upper surface on the thorn pricking conveyor line 81, so that the fibers of adjacent two layers of materials are excessively connected. Specifically, the thorn pricking conveyor line 81 includes two sets of oppositely arranged conveying and clamping modules 811. The two sets of conveying and clamping modules 811 are arranged up and down relatively to clamp and convey the compacted material. The first thorn pricking assembly 82 includes a first support platform 821, a first needle plate 822, and a first thorn pricking driving module 823. The first support platform 821 is provided with a first support driving module 824. The first support driving 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 thorn pricking needles 8221 are uniformly distributed on the first needle plate 822. The first thorn pricking driving module 823 is used to drive the first needle plate 822 to drive the first thorn pricking needles 8221 to prick the surface of the material. The second thorn pricking assembly 83 includes a second support platform 831, a second needle plate 832, and a second thorn pricking driving module 833. The second support platform 831 is provided with a second support driving module 834. The second support driving module 834 is used to drive the second support platform 831 so that the lower surface of the second support platform 831 fits the upper surface of the material. A plurality of second thorn pricking needles 8321 are uniformly distributed on the second needle plate 832. The second thorn pricking driving module 833 is used to drive the second needle plate 832 to drive the second thorn pricking needles 8321 to prick the bottom surface of the material. In this embodiment, through the design of the thorn pricking conveyor line 81, the thorn pricking mechanism 8 realizes the precise clamping and stable conveying of the edge of the compacted material. In the preparation process of ultra-high molecular weight polyethylene materials, the uniformity and stability of the compacted material are crucial. The two sets of oppositely arranged conveying and clamping modules 811 of the thorn pricking conveyor line 81 work together up and down to ensure that the material will not shift or loosen during the conveying process, providing a solid foundation for the subsequent thorn pricking operation. This characteristic is of great significance for ensuring the dimensional accuracy and uniformity of ultra-high molecular weight polyethylene stab-resistant and cut-resistant materials during the processing. Secondly, the sequential arrangement of the first thorn pricking assembly 82 and the second thorn pricking assembly 83 realizes the comprehensive thorn pricking treatment of the upper and lower surfaces of the material. The first thorn pricking assembly 82 utilizes the design of the first support platform 821 and the first needle plate 822. Driven by the first thorn pricking driving module 823, the first thorn pricking needles 8221 can penetrate into the upper surface of the material to form effective fiber connection points. This step not only enhances the fiber interweaving degree on the surface layer of the material but also improves the overall strength of the material.Subsequently, under the action of the second stabbing component 83 on the second support platform 831 and the second needle plate 832, the lower surface of the material is stabbed, further promoting the excessive connection of the fibers of adjacent layers of the material. This double-sided stabbing treatment of the upper and lower surfaces significantly improves the interlayer bonding force and the overall puncture and cut resistance of the ultra-high molecular weight polyethylene puncture and cut resistant material. Moreover, the design of the stabbing mechanism 8 fully considers the support and fitting requirements of the material. The first support platform 821 and the second support platform 831 are respectively driven by the first support driving module 824 and the second support driving module 834, and can adjust the support position according to the actual situation of the material to ensure that the material is fully supported and fitted during the stabbing process. This flexible and adjustable support method not only improves the accuracy and efficiency of stabbing, but also effectively avoids problems such as uneven stabbing caused by material deformation. Finally, the stabbing mechanism 8 can significantly improve the puncture and cut resistance level of the material during the preparation process of the ultra-high molecular weight polyethylene puncture and cut resistant material. Through fine stabbing treatment, the fiber structure inside the material is effectively strengthened and reorganized, forming a more compact and solid fiber network. This structural optimization enables the ultra-high molecular weight polyethylene puncture and cut resistant material to better disperse and absorb energy when facing the impact of sharp objects, thus significantly enhancing its puncture and cut resistance performance.

[0049] Refer to Figures 9 to 10As shown, it further includes a trimming mechanism 30 and a detection mechanism 40. The second thorn pricking assembly 83 conveys the material after being pricked towards 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 being secondarily compacted. 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 to adjust the trimming of edges in different directions. The pressing module 301 includes a pressing table 3011 and a pressing driving module 3012. The pressing driving module 3012 is provided with a pressing plate 3013. The rotating module 302 is used to drive the pressing table 3011 to rotate. The edge cutting module 303 includes a trimming driving module 3031 and a trimming tool 3032. The trimming tool 3032 is used for trimming the edge of the material. Specifically, the detection mechanism 40 includes a detection conveying assembly 401, a laser thickness measuring element 402, and a weight detection assembly 403. The detection conveying assembly 401 is used to receive the material trimmed by the trimming mechanism 30 and convey it. A detection box 404 is arranged on the detection conveying assembly 401. The laser thickness measuring element 402 is arranged in the detection box 404 to measure the thickness of the material. The weight detection assembly 403 is arranged on the detection conveying assembly 401 and is used to detect the weight of the material. A detection material taking assembly 4011 is arranged on one side of the detection conveying assembly 401. The detection material taking assembly 4011 is used to grab the material on the trimming mechanism 30 and place it on the detection conveying assembly 401. After the detection conveying assembly 401 completes the detection, it conveys the material to the material receiving mechanism 9 for material receiving. In this embodiment, through the coordinated action of the pressing module 301, the rotating module 302, and the edge cutting module 303 of the trimming mechanism 30, precise trimming of the edges of the material after being secondarily compacted is achieved. The pressing module 301 ensures the stability of the material during trimming. The rotating module 302 flexibly adjusts the direction of the material, enabling the edge cutting module 303 to comprehensively and evenly trim the edges of the material, thereby effectively improving the appearance quality and dimensional accuracy of the material. Secondly, through the comprehensive application of the detection conveying assembly 401, the laser thickness measuring element 402, and the weight detection assembly 403 of the detection mechanism 40, multi-dimensional detection of the trimmed material is achieved. The laser thickness measuring element 402 can accurately measure the thickness of the material to ensure that the material meets specific anti-stabbing and anti-cutting performance requirements. The weight detection assembly 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 material taking assembly 4011 realizes the efficient and automatic transfer of the material from the trimming mechanism 30 to the detection conveying assembly 401, avoiding errors and safety hazards that may be brought by manual operation. At the same time, after the detection conveying assembly 401 completes the detection, it can automatically convey the material to the material receiving mechanism 9 for material receiving, thereby improving the automation degree and production efficiency of the entire preparation process.
