Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a high-precision double-sided circular knitting machine. Background Technology

[0002] As the textile industry's demands for fabric quality and production efficiency continue to rise, the shortcomings of traditional double-sided circular knitting machines in terms of knitting precision and stability are becoming increasingly apparent. Existing equipment often suffers from uneven yarn tension due to unstable support structures and easy deviations in the feeding system, resulting in inconsistent fabric density and numerous defects. Defects in the protective design allow foreign objects to easily enter the knitting area, affecting product quality. At the same time, unreasonable lighting and observation designs increase the difficulty and error rate of manual inspection.

[0003] A search revealed Chinese Patent Publication No. CN219508139U, which discloses a high-precision double-sided circular knitting machine. The machine includes a support frame, a support ring, a needle cylinder, a yarn guiding mechanism, and a winding mechanism. The support frame is arranged in a ring on the outer circumference of the support ring. The needle cylinder is rotatably connected inside the support ring. The yarn guiding mechanism is connected to a column via a fixing ring, and the column is fixed to the support ring. The winding mechanism is connected to the needle cylinder and is connected to the support frame via a first limiting component. The support frame has a rotating guardrail, and the winding mechanism is connected to the rotating guardrail via a second limiting component. A base assembly is located at the bottom of the winding mechanism. This invention, through the design of the first limiting component, the second limiting component, and the base assembly, not only supports and limits the winding mechanism but also improves its stability and reliability during rotation, enabling it to handle heavier fabric rolls.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the yarn bobbin positioning structure of the traditional feeding component of the aforementioned device is prone to shaking due to high-speed rotation, lacking a reliable anti-dropping damping mechanism, which may lead to yarn tension fluctuations affecting weaving accuracy; existing protective structures mostly focus on limiting the winding mechanism, and lack sufficient integration of foreign object protection and real-time observation functions in the textile area, making it difficult for operators to clearly view the status of semi-finished fabrics during production, and lacking targeted lighting auxiliary devices. Utility Model Content

[0005] To overcome the technical defects of the existing technology, this utility model provides a high-precision double-sided circular knitting machine.

[0006] The technical solution adopted by this utility model is: a high-precision double-sided circular knitting machine, including a support component, a protective component on one side of the support component, and a textile component and a feeding component on the top of the support component. Through the above scheme, the support components and protective components form a stable mechanical structure, and the textile components and feeding components work together to achieve high-precision weaving. The overall structure is compact and has a high degree of functional integration.

[0007] The protective components include a protective railing for safety protection, an observation window side panel for preventing foreign objects from entering the textile area, and an observation window body for observing semi-finished fabrics. The above solution forms a physical barrier between the guardrail and the side panel of the observation window, while the observation window itself is made of transparent material to achieve visual monitoring, effectively improving the safety and ease of operation of the equipment.

[0008] The above solution achieves a triple-structure design for the protective components, which not only meets safety requirements but also forms a closed protection system with the observation window side panel and the observation window body through a sealed connection, preventing flying shavings or foreign objects from interfering with the textile process.

[0009] The feeding assembly includes a spinning bobbin mounting plate for guiding the yarn and a positioning post for mounting the yarn bobbin. A bearing ring is movably sleeved on one side of the positioning post, and an elastic damping ring is fixedly sleeved on one side of the bearing ring to prevent the yarn bobbin from falling off.

[0010] The above solution enables precise yarn guidance through the cooperation of the spinning bobbin mounting plate and the positioning column. The damping ring is made of silicone rubber to form an interference fit, which effectively prevents the yarn bobbin from falling off during high-speed operation.

[0011] Preferably, the support assembly includes a first support column for supporting the feeding assembly. The first support column is fixedly installed on the top of the chassis. A central control screen is provided on one side of the first support column. A second support column is fixedly installed on the top of the first support column. A limit block is fixedly connected to one side of the second support column for supporting the spinning bobbin mounting plate.

[0012] Through the above scheme, the first support column and the second support column form a multi-level support structure, the central control screen realizes human-computer interaction, and the limit block accurately positions the spinning bobbin mounting plate, thereby improving the feeding stability.

[0013] Preferably, the protective assembly further includes a searchlight fixedly installed on one side of the first support column, the searchlight illuminating the semi-finished textile fabric at the bottom of the textile assembly.

[0014] The above solution uses high-brightness LED light sources, such as lumens or more, to shine directly on the bottom of the textile area, ensuring that operators can clearly observe the status of semi-finished products and adjust process parameters in a timely manner.

[0015] Preferably, each of the spinning bobbin mounting discs has a positioning block fixedly connected to its bottom, and the positioning block is fixedly sleeved between the two locking blocks of the limiting block.

[0016] Through the above scheme, the positioning block and the limiting block cooperate to form a mechanical lock. The inner side of the locking block is provided with anti-slip texture to enhance friction and prevent the spinning bobbin mounting plate from shifting during high-speed rotation.

[0017] Preferably, the observation window side panel is vertically fixed to the inner edge of the guardrail, and the observation window side panel is sealed to the observation window body to form a closed protective structure.

[0018] The above solution uses an O-ring seal between the side panel and the main body of the observation window, effectively preventing fly shavings and dust from entering the textile area while ensuring the clarity of the observation field.

[0019] Preferably, a rotational fit clearance is provided between the positioning pin and the bearing ring, and the damping ring is made of silicone rubber with an outer diameter larger than the inner diameter of the yarn bobbin to form an interference fit.

[0020] The above scheme allows the yarn bobbin to rotate freely through the rotational fit clearance, and the interference fit of the damping ring provides moderate resistance to avoid weaving defects caused by yarn tension fluctuations. At the same time, the silicone rubber material has both elasticity and wear resistance.

[0021] Preferably, the thickness of the limiting block matches the spacing between the two locking blocks of the positioning block, and the inner side of the locking block is provided with anti-slip texture to enhance the fixing effect on the positioning block.

[0022] Through the above solution, the dimensions of the limit block and the positioning block are precisely matched, and the anti-slip texture is made of silicone rubber or polyurethane material, which further improves the connection tightness and ensures that the feeding component remains stable during long-term operation.

[0023] The beneficial effects of this utility model are as follows: By setting up components such as protective railings, observation window side panels, observation window bodies, and searchlights, and through the sealed connection between the protective railings and the observation window side panels and bodies, the observation window system can isolate and protect the textile area through a closed structure, preventing foreign objects from entering. Simultaneously, the searchlight illuminates the semi-finished fabric at the bottom of the textile assembly, allowing operators to clearly observe the weaving status through the observation window body. This achieves the effect of real-time assurance of fabric quality during the textile process through multiple layers of protection and visual monitoring, reducing interference from impurities and defects. By setting up components such as a spinning bobbin mounting plate, positioning posts, bearing rings, and damping rings, and through the rotational fit between the positioning posts and bearing rings, and the interference fit between the damping rings and the yarn bobbins, the bearing rings can stably limit the yarn bobbins through the elastic damping rings, allowing the yarn bobbins to rotate freely during feeding while preventing them from falling off. At the same time, the spinning bobbin mounting plate achieves quick installation through the snap-fit ​​structure of the positioning blocks and limiting blocks. This allows the device to stabilize the yarn feeding process through precise feeding positioning and tension control, thereby improving weaving accuracy and production efficiency.

[0025] The present invention will be further described below with reference to the accompanying drawings: like Figure 1 and Figure 2 As shown, this embodiment provides a high-precision double-sided circular knitting machine, including a support assembly 1. The support assembly 1 includes a first support column 101 for supporting a feeding assembly 4. The first support column 101 is fixedly installed on the top of the chassis. A central control screen 102 is provided on one side of the first support column 101, which can realize real-time monitoring and intelligent control of parameters. A second support column 103 is fixedly installed on the top of the first support column 101. A limit block 104 is fixedly connected to one side of the second support column 103, which supports the spinning bobbin mounting plate 401 by precise positioning, ensuring the stable operation of the feeding system. like Figure 1 and Figure 3 As shown, a protective component 2 is provided on one side of the support component 1. The protective component 2 includes a protective railing 201 for safety protection, an observation window side panel 202 for preventing foreign objects from entering the textile area, and an observation window body 203 for observing the semi-finished fabric. Its closed structure can effectively isolate external interference, while ensuring clear observation through high light transmittance materials. The protective component 2 also integrates an airflow guiding design to reduce the impact of fly waste deposition on weaving accuracy. like Figure 1 and Figure 4As shown, the top of the support assembly 1 is provided with a textile assembly 3 and a feeding assembly 4. The feeding assembly 4 includes a spinning bobbin mounting plate 401 for guiding the yarn and a positioning post 403 for mounting the yarn bobbin. A bearing ring 404 is movably sleeved on one side of the positioning post 403. Its rotational fit clearance optimization design can reduce friction loss. An elastic damping ring is fixedly sleeved on one side of the bearing ring 404. It is made of silicone rubber and uses an interference fit to prevent the yarn bobbin from falling off, while absorbing running vibration. like Figure 2 and Figure 3 As shown, the protective component 2 also includes a searchlight 204 fixedly installed on one side of the first support column 101. The searchlight 204 is directed towards the semi-finished textile fabric at the bottom of the textile component 3. It uses a high-brightness LED light source to achieve directional lighting, which facilitates real-time observation of the weaving status. The observation window side plate 202 is vertically fixed to the inner edge of the protective railing 201. The observation window side plate 202 is sealed to the observation window body 203 to form a closed protective structure, which effectively blocks dust and foreign objects from entering.

[0026] like Figure 2 and Figure 4 As shown, each of the bottom of the spinning bobbin mounting plate 401 is fixedly connected with a positioning block 402. The positioning block 402 is fixedly sleeved between the two locking blocks of the limiting block 104, and the thickness of the limiting block 104 matches the distance between the two locking blocks of the positioning block 402. The inner side of the locking block is provided with anti-slip texture to enhance the fixing effect of the positioning block 402. By increasing the contact friction coefficient, the mounting plate is ensured to remain stable during high-speed operation. like Figure 4 and Figure 5 As shown, a rotational fit clearance is provided between the positioning post 403 and the bearing ring 404. The damping ring is made of silicone rubber, and its outer diameter is larger than the inner diameter of the yarn bobbin to form an interference fit. This can not only adapt to the installation requirements of yarn bobbins of different specifications, but also provide adaptive clamping force through elastic deformation to prevent the yarn from shifting during high-speed conveying. Example

[0027] Daily fabric production operations In a knitted fabric production workshop, operators prepare to use a high-precision double-sided circular knitting machine to knit polyester fabric. First, preparations are made before starting the equipment: the operator stands beside support assembly 1 and sequentially mounts multiple yarn bobbins onto the positioning post 403 of the feeding assembly 4. Because a bearing ring 404 is movably fitted onto one side of the positioning post 403, and a silicone rubber damping ring is fixedly fitted onto the other side of the bearing ring 404, the operator securely fixes the yarn bobbins to the positioning post 403 through the interference fit between the damping ring and the inner diameter of the yarn bobbin, preventing the yarn bobbins from falling off during feeding.

[0028] Next, the operator places the spinning bobbin mounting plate 401 onto the limiting block 104 on one side of the second support column 103 in the support assembly 1 using the positioning block 402 at the bottom. Because the thickness of the limiting block 104 matches the spacing between the two locking blocks of the positioning block 402, and because the inner side of the locking block has anti-slip texture, the spinning bobbin mounting plate 401 is stably fixed to the top of the support assembly 1. After completing the installation of the feeding assembly 4, the operator inputs the fabric weaving parameters, including yarn tension and weaving speed, on the central control screen 102. After the equipment is started, the textile assembly 3 begins to operate. The yarn from the feeding assembly 4 is guided to the textile assembly 3 for weaving via the spinning bobbin mounting plate 401. During equipment operation, the operator can clearly observe the weaving process of the semi-finished fabric through the enclosed protective structure formed by the observation window body 203 and the observation window side plate 202 of the protective assembly 2. The guardrail 201 effectively prevents the operator from accidentally coming into contact with the high-speed rotating textile assembly 3, ensuring operational safety. When a spool of yarn is used up, the operator shuts down the equipment and easily removes the empty yarn bobbin through the rotational fit clearance between the bearing ring 404 and the positioning column 403, replaces it with a new yarn bobbin, and continues production.

[0029] The implementation principle of a high-precision double-sided circular knitting machine according to an embodiment of this application is as follows: First, the yarn bobbin in the feeding assembly 4 is mounted on the positioning post 403. The bearing ring 404 and the damping ring are made of silicone rubber and form an elastic interference fit, which allows the yarn bobbin to rotate freely with the yarn traction, and stabilizes the yarn tension through damping force. The positioning block 402 at the bottom of the spinning bobbin mounting plate 401 is engaged between the anti-slip blocks of the limiting block 104 to ensure accurate positioning of the mounting plate when rotating at high speed. After the yarn is drawn out from the yarn bobbin, it is guided into the textile assembly 3 in an orderly manner through the guide structure on the mounting plate, avoiding weaving defects caused by shaking or uneven tension. Through the above structure, the feeding system achieves stable yarn supply and tension balance, laying the foundation for high-precision weaving. Secondly, the textile assembly 3 is based on the principle of a double-sided circular knitting machine. The upper and lower cylinders rotate synchronously at high speed, and the knitting needles move radially under the control of the cam to complete actions such as hooking yarn, bending yarn, and forming loops. Multiple strands of yarn from the feeding assembly 4 enter the feeding nozzles of the upper and lower cylinders respectively, and are interwoven by the knitting needles to form a double-sided structure. The first support column 101 and the second support column 103 of the support assembly 1 are connected by a multi-level rigid connection, and the positioning of the spinning cylinder mounting plate 401 is coordinated with the limit block 104 to ensure that the textile assembly 3 maintains coaxiality when running at high speed, reducing the impact of vibration on the knitting accuracy. During this process, the yarn is precisely guided and works in coordination with the movement trajectory of the knitting needles to achieve uniform knitting of the double-sided fabric. Next, the protective railing 201 of the protective component 2 forms a safety barrier around the equipment to prevent operators from accidentally contacting high-speed rotating parts; the observation window side panel 202 and the observation window body 203 are connected by a sealed connection to form a closed structure, blocking foreign objects such as flying flowers and dust from entering the textile area, avoiding contamination of the fabric or jamming of the knitting needles; the searchlight 204 installed on the first support column 101 shines directly on the semi-finished fabric at the bottom of the textile component 3, and the operator can clearly see the weave pattern, density and whether there are any defects in the fabric through the observation window.

[0030] Next, the central control screen 102 on the side of the support component 1 integrates the equipment control system. Operators can input weaving parameters through the touch interface. The system collects data such as the rotation speed, yarn tension, and fabric output speed of the textile component 3 in real time through sensors. After comparing with the preset parameters, it automatically adjusts the damping force of the bearing ring 404 and the cylinder rotation speed of the feeding component 4.

[0031] Finally, the woven semi-finished fabric is exported from the bottom of the textile assembly 3 and conveyed to the subsequent processing steps by the traction rollers (not marked in the diagram). Because the observation window system provides a clear view, the operator can conduct spot checks in real time during the fabric output process. If defects are found, the equipment can be paused and the process adjusted via the central control screen 102. During long-term operation of the equipment, the rotational fit clearance between the positioning column 403 and the bearing ring 404, the elastic performance of the damping ring, and the anti-slip structure between the limit block 104 and the positioning block 402 are all designed to be wear-resistant, reducing component wear. Regular maintenance only requires checking the sealing of the guardrail 201, the lighting effect of the searchlight 204, and the lubrication status of each moving part to ensure the continuous and stable operation of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.

All such changes and modifications fall within the scope of the invention as claimed, which is defined by the appended claims and their equivalents.
