Description

Technical Field

[0001] This utility model relates to the field of textile needle manufacturing technology, and in particular to a high-precision cooling structure for processing the tongue groove of a knitting needle. Background Technology

[0002] Textile needles are one of the core components of textile machinery, and their performance directly affects the quality of textiles and production efficiency. With the rapid development of the textile industry, higher demands are being placed on the precision and durability of knitting needles. The groove, as a key structure of the knitting needle, directly affects its performance due to its machining accuracy. However, during machining, the high-speed friction between the cutting tool and the workpiece generates a large amount of heat, causing localized temperature increases in the workpiece, which in turn affects machining accuracy and tool life. Currently, the textile needle manufacturing industry commonly uses traditional coolant spraying for cooling, but its cooling efficiency and precision are insufficient to meet the demands of high-precision machining.

[0003] A search revealed Chinese patent publication number CN221134203U, which discloses a milling machine for machining needle tongue assembly holes. The machine includes a support table, a support frame fixedly connected to the top of the support table, a drilling frame fixedly connected to one side of the support frame, a first stabilizing frame fixedly connected to one side of the support table, a drive motor fixedly connected inside the first stabilizing frame, and a first rotating roller fixedly connected to the output end of the drive motor via a coupling. A second stabilizing frame is fixedly connected to one side of the support table. This invention, when machining the needle body, places the needle body inside a rubber belt, turns on the drive motor to drive the first rotating roller to rotate, and uses a conveyor belt and a second rotating tube for transmission, allowing the needle body to pass through the drilling frame for drilling. The trapezoidal groove inside the rubber belt limits and stabilizes the needle body.

[0004] The commonly used cooling methods in the prior art mainly include the following: First, the traditional coolant spraying method, which sprays coolant onto the processing area through nozzles. However, due to the fixed position of the nozzles, it is difficult for the coolant to accurately cover the high-temperature area. Second, the air cooling method, which uses compressed air to cool the processing area. However, the cooling effect is limited and it is difficult to effectively reduce the workpiece temperature. Third, the indirect cooling method, which indirectly cools the workpiece through cooling fixtures or cooling plates. However, the cooling efficiency is low and it is difficult to meet the cooling requirements of complex-shaped workpieces. In practical applications, these methods all have problems such as uneven cooling, low cooling efficiency, and insufficient cooling precision. Therefore, a high-precision cooling structure for knitting needle tongue groove processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a high-precision cooling structure for the processing of knitting needle tongue grooves, which aims to improve the problems of uneven cooling, low cooling efficiency, and insufficient cooling precision in some existing fixtures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-precision knitting needle tongue groove processing cooling structure includes a base, a support platform fixedly connected to the top of the base, a support frame fixedly connected to the rear side of the support platform, a drilling frame fixedly connected to the front side of the support frame, a sliding table slidably connected to the top of the support platform, a fixing mechanism provided inside the sliding table, a cooling mechanism fixedly connected to the top left side of the base, and a dust removal mechanism fixedly connected inside the sliding table. The cooling mechanism includes a liquid storage tank, a first conveying pipe fixedly connected to the front side of the liquid storage tank, a pump body fixedly connected to the front side of the first conveying pipe, a second conveying pipe fixedly connected to the output end of the pump body, a coolant guiding assembly fixedly connected to the rear side of the sliding table, a temperature sensor fixedly connected to the top right side of the sliding table, and a control box fixedly connected to the top right side of the base. Through the above technical solution: the high-precision knitting needle tongue groove processing cooling structure achieves comprehensive optimization of the processing process. The cooling mechanism accurately delivers coolant to the processing area through a storage tank, pump body, and delivery pipeline. The temperature sensor and control box work together to maintain temperature stability. The fixed mechanism's conveyor belt, rubber belt, and trapezoidal groove firmly clamp and automatically transport the workpiece. The dust removal mechanism uses a dust collection box and dust collection pump to clean up dust, ensuring the processing environment and equipment operation, and comprehensively improving processing accuracy and efficiency.

[0007] As a further description of the above technical solution: The coolant guiding assembly includes a guide plate, the front side of which is fixedly connected to the rear side of the sliding table, and a nozzle is fixedly connected to the top of the guide plate. Through the above technical solution, the coolant guiding assembly achieves precise guidance of coolant spray. The guide plate is fixed to the rear side of the sliding table, providing stable support for the nozzle and ensuring its stable position during processing. The nozzle is installed on the top of the guide plate, which can accurately spray the coolant from the pump body through the delivery pipeline into the knitting needle tongue groove processing area in a predetermined direction, effectively improving the cooling effect and ensuring processing accuracy.

[0008] As a further description of the above technical solution: The fixing mechanism includes a conveyor belt, the bottom of which is located inside the sliding table, and a rubber belt is fixedly connected to the outside of the conveyor belt. Multiple trapezoidal grooves are opened inside the rubber belt, and a storage box is fixedly connected to the top right side of the base. Through the above technical solution, the fixing mechanism realizes the fully automated operation of workpieces such as knitting needles from fixing to collection. The conveyor belt runs inside the sliding table, driving the externally connected rubber belt to move. The trapezoidal groove on the rubber belt provides stable clamping according to the workpiece specifications, preventing workpiece displacement during processing. After processing, the conveyor belt transports the workpiece to the storage box on the right side of the base, avoiding damage caused by manual collection and improving processing efficiency.

[0009] As a further description of the above technical solution: The dust removal mechanism includes a dust collection box, the outside of which is fixedly connected to the inside of the sliding table. A dust collection pipe is fixedly connected to the bottom of the dust collection box. A fixed box is fixedly connected to the front of the dust collection pipe. A second dust collection pipe is fixedly connected to the front of the fixed box. A dust pump is fixedly connected to the rear of the second dust collection pipe. A filter plate is detachably connected inside the fixed box. Limiting components are rotatably connected to both the left and right sides inside the fixed box. Through the above technical solution: the dust removal mechanism achieves efficient collection and filtration of dust in the processing area. The dust pump generates strong suction, which draws dust near the sliding table into the dust collection box through dust removal pipe 2, the fixed box and dust removal pipe 1. The filter plate in the fixed box can effectively block dust and prevent it from entering subsequent equipment. The limiting component facilitates the disassembly and installation of the filter plate, making maintenance convenient and ensuring the continuous and stable operation of the dust removal system, thus purifying the processing environment.

[0010] As a further description of the above technical solution: The limiting component includes a rotating rod, which is rotatably connected to the inside of the fixed box. The inside of the fixed box is provided with multiple arc-shaped cavities. A sliding block is slidably connected to the inner wall of the dust removal pipe. A spring is fixedly connected to one end of the sliding block. A rotating plate is fixedly connected to the adjacent side of the two sliding blocks. Two positioning rods are fixedly connected to the adjacent side of the two rotating plates. A handle is fixedly connected to the outside of the rotating rod. Through the above technical solution, the limiting component enables convenient installation and removal of the filter plate. Turning the handle drives the rotating rod to rotate, which in turn causes the rotating plate to rotate. The rotating plate drives the sliding block to compress the spring, while simultaneously causing the positioning rod to disengage from or contact the filter plate. The arc-shaped inner cavity inside the fixed box helps guide the dust airflow. While ensuring the filter plate is stably installed, it also facilitates maintenance personnel to clean and replace it, ensuring the long-term stable operation of the dust removal system.

[0011] As a further description of the above technical solution: One of the adjacent sides of the plurality of positioning rods contacts the front and rear sides of the filter plate, and the left and right sides of the two rotating plates are rotatably connected to the left and right sides inside the fixed box. Through the above technical solution, multiple positioning rods closely contact the front and rear sides of the filter plate. Combined with the rotating plate's rotating connection design on the left and right sides inside the fixed box, the filter plate is securely fixed inside the fixed box. When maintenance is required, rotating the relevant parts can disengage the positioning rods from the filter plate, enabling convenient disassembly. This ensures that the filter plate can stably perform its filtering function during operation and facilitates daily maintenance.

[0012] As a further description of the above technical solution: The bottom of the fixed box is fixedly connected to the top front side of the base, and the bottom of the vacuum pump is fixedly connected to the top left side of the base; Through the above technical solution: the fixed box and the dust pump can be firmly installed on the base. The fixed box is located on the top front side of the base, which forms a stable support structure for the internal filter plate and the connected dust collection pipe, which facilitates dust collection and filtration operations. The dust pump is fixed on the top left side of the base to ensure its stability during operation, continuously provide strong suction for the dust removal system, and ensure the efficient operation of the entire dust removal mechanism.

[0013] As a further description of the above technical solution: The bottom of the pump body is fixedly connected to the top left side of the base, and the bottom of the support frame is fixedly connected to the top rear side of the base. Through the above technical solution, the pump body and support frame are securely installed on the base. The pump body is located on the top left side of the base, ensuring stable operation when providing power to the cooling system and guaranteeing the continuous delivery of coolant. The support frame is fixed on the top rear side of the base, providing reliable support for components such as the drilling frame, making the entire processing equipment structure stable.

[0014] This utility model has the following beneficial effects: 1. In this invention, the pump starts, drawing coolant from the storage tank and delivering it through a pipeline to an adjustable nozzle mounted on a guide plate. The guide plate is fixed to the worktable of the processing equipment. A temperature sensor monitors the workpiece temperature in real time and transmits the data to the control unit. The control unit adjusts the pump output flow rate and the position of the adjustable nozzle based on a preset temperature threshold. When the temperature is too high, the pump flow rate is increased and the nozzle position is adjusted to ensure the coolant precisely covers the high-temperature area; when the temperature is normal, the current state is maintained, ensuring a uniform and stable temperature in the processing area and guaranteeing smooth processing. This achieves high-precision cooling during the processing of the knitting needle tongue groove, ensuring temperature uniformity and stability in the processing area, improving processing accuracy, extending tool life, and reducing processing costs.

[0015] 2. In this utility model, after starting the conveyor belt, the conveyor belt drives the rubber belt to move. Then, starting the dust pump allows dust inside the dust collection box to enter the fixed box through the dust removal pipe. The dust is blocked by the filter plate, thus removing dust from the dust removal pipe. When disassembly is required, the fixed box cover is opened, and the handle is turned. The handle drives the rotating rod to rotate, which in turn drives the rotating plate to rotate. The rotating plate drives the sliding block to rotate, which in turn compresses the spring. This causes the rotating plate to drive the positioning rod to rotate, thus removing dust from the trapezoidal groove inside the rubber belt and disassembling the filter plate. This prevents dust and other impurities from entering the processing area, avoiding interference between the tool and the workpiece due to impurities, further improving processing accuracy, reducing dust during processing, improving the air quality in the workshop, providing a healthier working environment for operators, and facilitating the cleaning of the filter plate.

The cooling mechanism 7 includes a liquid storage tank 71, a first delivery pipe 72 fixedly connected to the front of the liquid storage tank 71, a pump body 73 fixedly connected to the front of the first delivery pipe 72, the pump body 73 pressurizes the pump to overcome the pipe resistance and meet the flow rate and volume requirements of the processing area to efficiently push the coolant to the adjustable nozzle 75, the output end of the pump body 73 is fixedly connected to a second delivery pipe 74, a coolant guide assembly is fixedly connected to the rear of the sliding table 5, and a temperature sensor 77 is fixedly connected to the top right side of the sliding table 5. The temperature sensor 77 is closely attached to the processing area to sense the temperature change of the workpiece in real time and quickly transmit the data to the control unit in the control box 78. The control unit intelligently regulates the output flow of the pump body 73 and the position of the adjustable nozzle 75 according to the preset temperature threshold to maintain the temperature stability of the processing area. The control box 78 is fixedly connected to the top right side of the base 1. The coolant guiding assembly includes a guide plate 76. The front side of the guide plate 76 is fixedly connected to the rear side of the sliding table 5. The top of the guide plate 76 is fixedly connected to the nozzle 75. The storage tank 71 ensures that there is sufficient coolant supply throughout the processing. The first conveying pipe 72 connects the storage tank 71 and the pump body 73 to deliver the coolant to the pump body 73. The second conveying pipe 74 accurately delivers the coolant pressurized by the pump body 73 to the adjustable nozzle 75 to ensure stable and smooth coolant delivery. The bottom of the pump body 73 is fixedly connected to the top left side of the base 1. The bottom of the support frame 3 is fixedly connected to the top rear side of the base 1. Specifically, it achieves precise temperature control and cooling during the processing. Coolant is stored in the storage tank 71 in the cooling mechanism 7. The pump body 73 delivers the coolant to the nozzle 75 of the coolant guide assembly through the first delivery pipe 72 and the second delivery pipe 74. The nozzle 75 sprays coolant onto the processing area. The temperature sensor 77 monitors the temperature of the workpiece on the sliding table 5 in real time and transmits the data to the control unit in the control box 78. The control unit precisely adjusts the output flow of the pump body 73 and the position of the nozzle 75 according to the preset temperature threshold to ensure the uniformity and stability of the temperature in the processing area. This avoids the processing accuracy of the needle groove due to excessive temperature and ensures the smooth progress of high-precision needle groove processing.

[0020] Reference Figure 2 and Figure 3 The fixing mechanism 6 includes a conveyor belt 62, which is installed inside the sliding table 5. Upon startup, the conveyor belt 62 drives the connected rubber belt 61 to move cyclically. This not only fixes the workpiece during processing but also transports it orderly to the storage box 64 after processing, greatly improving the automation level of the processing flow. The bottom of the conveyor belt 62 is located inside the sliding table 5, and the rubber belt 61 is fixedly connected to the outside of the conveyor belt 62. Multiple trapezoidal grooves 63 are evenly distributed on the rubber belt 61, providing suitable clamping space for different specifications of knitting needles. Due to the flexibility of the rubber belt 61, it can closely fit the workpiece, effectively preventing workpiece displacement during processing and ensuring processing accuracy. Multiple trapezoidal grooves 63 are opened inside the rubber belt 61. The storage box 64 is fixedly connected to the top right side of the base 1. Specifically, the fixing mechanism 6 moves the rubber belt 61 fixedly connected to it by the operation of the conveyor belt 62 inside the sliding table 5. The multiple trapezoidal grooves 63 on the rubber belt 61 can provide a stable clamping effect for workpieces such as knitting needles. Different specifications of knitting needles can be adapted to different trapezoidal grooves 63 to ensure that the workpieces will not be displaced during processing and to ensure processing accuracy. After processing is completed, the conveyor belt 62 can transport the processed workpieces to the storage box 64, realizing an integrated process from fixing the workpieces to collecting them after processing. This improves processing efficiency and avoids secondary damage that may occur when manually collecting workpieces, ensuring the efficient and orderly processing of high-precision knitting needle tongue grooves.

[0021] Reference Figure 2 , Figure 4 and Figure 5The dust removal mechanism 8 includes a dust collection box 813, which is externally and fixedly connected to the inside of the sliding table 5. A dust collection pipe 1 81 is fixedly connected to the bottom of the dust collection box 813, and a fixed box 82 is fixedly connected to the front of the dust collection pipe 1 81. A dust collection pipe 2 84 is fixedly connected to the front of the fixed box 82. The dust collection box 813, fixed inside the sliding table 5, is the terminal for dust collection. The dust collection pipe 1 81 connects the dust collection box 813 and the fixed box 82, and is responsible for sucking in the dust from the processing area. The dust collection pipe 2 84 transmits the suction force generated by the dust pump 85. The dust collection operation is completed collaboratively with the fixed box 82. A dust pump 85 is fixedly connected to the rear side of the dust collection pipe 84. The dust pump 85 serves as the power source for dust collection. After starting, it creates a strong negative pressure in the pipe. This negative pressure passes through the dust collection pipe 84, the fixed box 82, and the dust collection pipe 81, quickly sucking the dust generated in the processing area near the sliding table 5 into the dust collection box 813, effectively purifying the processing environment. A filter plate 83 is detachably connected inside the fixed box 82. Limiting components are rotatably connected to both the left and right sides inside the fixed box 82. The limiting components include rotating rods. 86. The rotating rod 86 is externally rotatably connected to the inside of the fixed box 82. The inside of the fixed box 82 is provided with multiple arc-shaped inner cavities 87. The inner wall of the dust removal pipe 81 is slidably connected to a sliding block 88. One end of the sliding block 88 is fixedly connected to a spring 89. A rotating plate 810 is fixedly connected to the adjacent side of the two sliding blocks 88. Two positioning rods 811 are fixedly connected to the adjacent side of the two rotating plates 810. The limiting assembly is used for the installation and removal of the filter plate 83. Rotating the handle 812 drives the rotating rod 86 to rotate, thereby causing the rotating plate 83 to rotate. 10. Rotation compresses the spring 89 via the sliding block 88, allowing the positioning rod 811 to disengage from or contact the filter plate 83, thus enabling convenient disassembly and stable installation of the filter plate 83. The rotating rod 86 is externally fixedly connected to a handle 812. The adjacent sides of multiple positioning rods 811 contact the front and rear sides of the filter plate 83. The left and right sides of the two rotating plates 810 are rotatably connected to the left and right sides inside the fixed box 82. The bottom of the fixed box 82 is fixedly connected to the top front side of the base 1. The bottom of the vacuum pump 85 is fixedly connected to the top left side of the base 1. Specifically, the dust removal mechanism 8 effectively cleans up the dust generated during the high-precision knitting needle tongue groove processing. After the dust pump 85 is started, it generates suction, which draws the dust generated in the processing area near the sliding table 5 into the dust collection box 813 through the second dust removal pipe 84, the fixed box 82, and the first dust removal pipe 81. When the dust enters the fixed box 82, the filter plate 83 filters it to prevent the dust from entering subsequent equipment and causing damage. By turning the handle 812, the rotating rod 86 is rotated, which in turn causes the limit component to move. The positioning rod 811 can disassemble and install the filter plate 83, making it convenient to clean and replace the filter plate 83. After the filter plate 83 is installed in place, the spring 89 pushes the sliding block 88, which drives the rotating plate 810 and the positioning rod 811 to fix the filter plate 83. The arc-shaped inner cavity 87 inside the fixed box 82 helps to guide the dust flow to the filter plate 83. This dust removal mechanism 8 effectively purifies the processing environment, avoids dust affecting the processing accuracy and normal operation of the equipment, and ensures the smooth progress of high-precision knitting needle tongue groove processing.

[0022] Working principle: In the high-precision knitting needle groove processing cooling structure, after the pump body 73 starts, it draws coolant from the storage tank 71 through the first delivery pipe 72, and then delivers it to the adjustable nozzle 75 installed on the upper end face of the guide plate 76 through the second delivery pipe 74. The guide plate 76 is fixed to the worktable such as the support table 2 of the processing equipment. The temperature sensor 77 monitors the workpiece temperature in real time and transmits the data to the control unit in the control box 78. The control unit adjusts the output flow rate of the pump body 73 and the position of the adjustable nozzle 75 according to the preset temperature threshold. If the temperature is too high, the output flow rate of the pump body 73 is increased and the position of the adjustable nozzle 75 is adjusted so that the coolant accurately covers the high-temperature area. If the temperature is normal, the current pump body 73 flow rate and nozzle 75 position are maintained to ensure the uniformity and stability of the temperature in the processing area and ensure the smooth progress of high-precision knitting needle groove processing.

[0023] After the conveyor belt 62 is started, it drives the rubber belt 61 to move. Then, the dust pump 85 is started, so that the dust inside the dust collection box 813 enters the fixed box 82 through the dust removal pipe 81. The dust is blocked by the filter plate 83, thus removing dust from the dust removal pipe 81. When disassembly is required, the fixed box 82 is opened and the handle 812 is turned. The handle 812 drives the rotating rod 86 to rotate, which in turn drives the rotating plate 810 to rotate. The rotating plate 810 drives the sliding block 88 to rotate, which in turn compresses the spring 89. This causes the rotating plate 810 to drive the positioning rod 811 to rotate, and after it disengages from the filter plate 83, the filter plate 83 can be disassembled, making it easier to clean.
