Description

A fully automatic production device for bionic ligament braiding materials

Technical field

The invention relates to the technical field related to bionic ligaments, and in particular to a fully automatic production device for bionic ligament braided materials.

Background technique

As the diagnosis of musculoskeletal disorders increases, however the diagnosis of joints is key, the initial assessment of joint laxity is manually estimated by the doctor by comparing the actual operation of the healthy limb with the injured limb, which is largely determined by The experience and proficiency of a physician that is typically gained through limited practice with anatomical models in medical education courses or by treating injured patients during limited work hours. Commercially available synthetic models primarily replicate geometric features and rarely reproduce the biologically true behavior of human tissues and joints. The fabrication of highly realistic synthetic models remains a challenge, which requires replicating not only bone geometry but also the mechanical properties of soft tissues, especially ligaments and tendons. The article "Reproduction of the mechanical behavior of ligament and tendon for artificial joint using bioinspired 3d braided fibers" by Ren Lei's team proposes bionic 3D fibers woven from commercial polyethylene fishing lines to reproduce the controlled nonlinearity of ligaments and tendons. Behavior, and in the process of use, the synthetic artificial model provides an economical and convenient alternative to the cadaver model, and has great market prospects and economic effects. A fully automatic production device for bionic ligament braiding materials has been developed to solve the problem that commercial polyethylene fishing lines on the market have a single style, and direct purchase and braiding cannot well reproduce the mechanical and biological properties of biological ligaments and joints. At the same time, how to restore the ligaments of different people, different age groups, and different parts in the most realistic and efficient manner is an urgent problem that needs to be solved. Therefore, a fully automatic production device for bionic ligament weaving materials is particularly needed.

However, there is currently no bionic ligament production device on the market that can produce the most realistic and efficient bionic ligament production device for different people, different age groups, and different parts according to actual needs. Instead, we directly purchase similar raw materials for weaving, which cannot well restore the real thing. ligament condition. The present invention consults a large amount of literature and information, and changes the diameter of the spray line mouth, heating temperature, stirring rate, and pressure during spraying to change the commercial polyethylene fishing line produced, so as to produce the closest mechanical properties and biological properties of human ligaments. Bionic ligaments. The diameters and structures of different ligaments are quite different. The finer nozzle diameter is suitable for manufacturing fine filaments, while the thicker nozzle diameter is suitable for making thick filaments. Moreover, the fibrosis temperature of different ligaments is different, and the temperature may be too high. Causes the fiber to over-melt, reducing the firmness and performance of the fiber; while the temperature is too low, it may not be fully fibrillated, resulting in the presence of unmelted fragments in the fiber. The fiber structure and fibrosis process of different ligaments have different requirements for the stirring rate. Stirring A rate that is too low may result in uneven mixing of the fibers. A stirring rate that is too high may cause the fibers to be too disordered and affect fiber quality. Different ligaments have different fibrosis processes and fiber morphology requirements, so the pressure during spraying needs to be adjusted.

The inner wall of the mixing barrel 3 is made of 316 stainless steel and is galvanized and polished, and the inner wall surface roughness Ra is 0.12-0.26um. The rotating mechanism 6 allows the mixing barrel 3 on the frame 1 to be supported by the slide rail system and can rotate. The fixed bracket 602 and the fixed rotating fixture 603 are used to support one end of the mixing barrel 3, and the mixing barrel 3 can be rotated by the fixed rotating fixture 603. The movable slide rail 607 can slide in the slide rail groove 601 to form a slide rail structure. The support position of the movable rotating fixture 604 can be changed by changing the position of the movable slide rail 607. To prevent shielding, the temperature sensor 701 is used to detect the internal temperature of the mixing barrel 3, the eddy current heater 702 is used to control the internal temperature of the mixing barrel 3, and the agitator 804 is connected by a variable frequency drive motor 801 through a gear box 802 and a transmission shaft 803 to ensure the requirements of different speeds and torques. After the polyethylene particles are input into the mixing barrel 3 and heated, the polyethylene inside is stirred and mixed. The stirred and mixed polyethylene will fall into the discharge pipe 901, and at this time, the mixing barrel 3 is rotated to a certain angle through the rotating mechanism 6, so that the polyethylene is accumulated at the barrel cover 5, and the servo motor 902 drives the screw extruder 903, and under the dual effects of gravity and the screw extruder 903, the polyethylene in the mixing barrel 3 is output to the discharge hose 904 through the discharge pipe 901. The end of the discharge pipe 901 is connected to the discharge hose 904 to facilitate the rotation of the spray line mechanism 10 within a certain range. The nozzle 1006 and the discharge hose 904 are connected to the pipeline 1002 through the sealing joint 1001. The sealing joint 1001 has the performance of high pressure and high temperature resistance, ensuring the stability and safety during the high pressure spraying process. The polyethylene is output to the connecting pipeline 1002 and is added through the pipeline. The heater 1003 heats and maintains a sufficiently high temperature to maintain the molten state of polyethylene, and outputs it through the high-pressure pump 1004. The pipe heater 1003 and the high-pressure pump 1004 control the biological and mechanical properties of commercial polyethylene fishing line to change at different temperatures and pressures, which can simulate the ligaments of human bodies of different ages, and the scope of application is further enhanced. The external rotation of the sealing joint 1001 is connected with a rotating disk 1005, and three groups of nozzles 1006 with different diameters (0.50mm, 0.40mm, 0.30mm) are installed on the rotating disk 1005. 5 is made of 120° rotatable fan-shaped galvanized copper sheet. The rotating disk 1005 can rotate according to the required line aperture to ensure that only one nozzle 1006 is aligned with the high-pressure pump 1004 for output work at any time. When cleaning is required, the line spraying mechanism 10 can be rotated to 150° with the help of the rotating mechanism 6 connected to the frame 1. At this time, through the cooperation of the pipeline heater 1003 and the high-pressure pump 1004, clean water is introduced into the line spraying mechanism 10 to effectively clean the blockage. This design not only ensures high efficiency and precise control during the spraying process, but also maintains the heating and cleaning system. The long-term availability and reliability of the spray head are ensured. The winding mechanism 11 is composed of a trapezoidal baffle 1106 and a high-speed rotating winding barrel 1104. The trapezoidal baffle 1106 takes into account the tilt angle and the groove, so that the fishing line coming out of the spray line mechanism 10 can enter the winding barrel 1104 at a precise position. The winding barrel 1104 is controlled by a gear control box 1102 and a second electric motor 1103. The second electric motor 1103 can adjust the speed of the winding barrel 1104 within the range of 5r/s to 25r/s through the gear control box 1102 to adapt to different thicknesses and strengths. Fishing line, during the winding process, the electric turntable 1101 drives the winding barrel 1104 to rotate gradually. After the winding barrel 1104 is full of winding, the electric turntable 1101 rotates the next unwound winding barrel 1104 to the front end of the line spraying mechanism 10 to ensure that the generated line is not overlapped. There are four winding barrels 1104 in total. The winding barrel 1104 is controlled by the winding sensor 1105 during the winding process to ensure the smooth transition of the wire and the correct winding tension. The design of the entire structure takes into account the convenience of operation and the ease of maintenance, while ensuring long-term stability and durability. Through these carefully designed components and mechanical connections, the winding mechanism 11 can efficiently and accurately complete its work, ensuring the production of high-quality polyethylene fishing line, thus completing the design of a fully automatic production device for bionic ligament braided materials.

In summary, the present invention is a fully automatic production device for bionic ligament braiding materials, which realizes automation in the entire bionic ligament production process, and can change the nozzle diameter, heating temperature, stirring rate, and other parameters according to actual needs.
