Description

Technical Field

[0001] This utility model relates to the field of circular knitting needles, and in particular to an anti-bending device for processing circular knitting needles. Background Technology

[0002] Circular knitting needles are crucial components in textile machinery, and their machining accuracy directly impacts the quality of textile products. As the textile industry's demands for high precision and efficiency continue to increase, the technical requirements for machining circular knitting needles are also rising. However, during the machining process, the slender needle body and insufficient rigidity make it prone to lateral bending, leading to decreased machining accuracy or even needle damage. Currently, the industry primarily addresses this by improving machining equipment and optimizing process parameters, but these methods have limited effectiveness and increase processing costs and time.

[0003] In existing technologies, support fixtures are commonly used to fix the needle body. The use of support fixtures limits processing flexibility, increases clamping time, and cannot effectively prevent the needle body from bending while ensuring processing efficiency. Moreover, the solutions are complex and costly, making it difficult to meet the needs of high-precision processing. Utility Model Content

[0004] This utility model proposes an anti-bending device for machining round needles, which aims to improve the problem that some existing devices cannot effectively prevent needle bending while ensuring processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A device for preventing lateral bending in the processing of circular needles includes a processing table. Two side-wing protective shells are fixedly connected to the top of the processing table. A transport module is installed in the middle of the processing table. A guide module is fixedly connected to the top of the two side-wing protective shells. The transport module includes a chain conveyor mounting frame. The outer side of the chain conveyor mounting frame is fixedly connected to the inside of the processing table. A first side-wing sprocket mounting bracket is fixedly connected to one outer side of the chain conveyor mounting frame. A drive motor is fixedly connected to the outer side of the first side-wing sprocket mounting bracket. A drive sprocket is fixedly connected to the drive end of the drive motor. The outer side of the drive sprocket is rotatably connected to the inside of the first side-wing sprocket mounting bracket. A second side-wing sprocket mounting bracket is fixedly connected to the other outer side of the chain conveyor mounting frame. A sprocket adjustment assembly is installed on one side of the second side-wing sprocket mounting bracket. A driven sprocket is rotatably connected to the outer side of the sprocket adjustment assembly. A conveyor chain is sleeved around the drive sprocket and the driven sprocket.

[0006] The above-described anti-bending device for circular needle machining effectively enhances stability and safety during processing by incorporating a side-wing protective shell and guide module on the machining table. The transport module utilizes a chain conveyor mounting frame, combined with a drive motor and active sprocket design, ensuring efficient material transport. Furthermore, the coordination between the sprocket adjustment assembly and the driven sprocket allows for flexible adjustment of chain tension and operating status, further improving the equipment's reliability and ease of operation.

[0007] As a further description of the above technical solution: Bottom sprocket mounting bases are fixedly connected to both sides of the bottom of the chain conveyor mounting frame. A fixing plate is fixedly connected to the bottom of the bottom sprocket mounting base. Bottom auxiliary sprockets are rotatably connected inside the fixing plate. The two bottom auxiliary sprockets are coupled to the conveyor chain on the outside.

[0008] The above solution involves a bottom design for the chain conveyor mounting frame. By fixing the bottom sprocket mounting base to both sides and equipping it with a fixing plate and a bottom auxiliary sprocket, the stability and reliability of the conveying system are enhanced. The coupling between the bottom auxiliary sprocket and the conveying chain ensures smooth operation of the chain, reduces friction and wear, and thus improves the overall conveying efficiency.

[0009] As a further description of the above technical solution: The sprocket adjustment assembly includes a sliding mounting block, the outer side of which is slidably connected to the second side sprocket mounting bracket. The outer side of the second side sprocket mounting bracket is fixedly connected to an electric push rod, the inner side of which is fixedly connected to the sliding mounting block. The drive end of the electric push rod is fixedly connected to the outer side of the sliding mounting block.

[0010] The above solution achieves flexible sprocket adjustment by connecting the sliding mounting block with the second side sprocket mounting bracket. The electric push rod allows the sliding mounting block to slide smoothly on the bracket, thus facilitating the adjustment of the relative position of the sprocket. This design not only improves the adjustment accuracy of the sprocket but also simplifies the operation process.

[0011] As a further description of the above technical solution: Multiple clamping modules are installed around the outside of the transport module. Each clamping module includes a support base. Each of the four corners of the support base is threaded with an anchor bolt. The external threads of the four anchor bolts are connected to the inside of the conveyor chain. A support frame is fixedly connected to the top of the support base. An electric push rod II is fixedly connected to one side of the outer side of the support frame. An ejector rod is fixedly connected to the drive end of the electric push rod II.

[0012] The above solution significantly improves the efficiency of material fixation and transportation by installing multiple clamping modules on the outer periphery. Each clamping module consists of a support base and mounting bolts, ensuring a stable connection with the conveyor chain and enhancing the overall structural stability. The support frame at the top of the support base, in conjunction with the electric push rod, allows for precise clamping and release of materials via the ejector rod.

[0013] As a further description of the above technical solution: The support frame is slidably connected to both sides of the support frame, and a sliding block is fixedly connected to the far side of the two sliding rods. A connecting rod is rotatably connected between the two sliding rods and the ejector rod. Two fixing blocks are fixedly connected to the top two sides of the support base. A clamping piece is fixedly connected to the sliding block and the adjacent side of the fixing block on the same side.

[0014] The above solution, with its sliding rods and sliding blocks on both sides of the support frame, combined with the rotating connection of the connecting rods, forms a flexible clamping mechanism. This structure allows the sliding blocks to move freely on the sliding rods, thereby achieving effective control of the clamping plates. The setting of the fixed blocks further enhances the tight connection between the clamping plates and the materials, ensuring the stability and safety of the materials during transportation.

[0015] As a further description of the above technical solution: The guide module includes two guide rail mounting bases. The bottom of the guide rail mounting bases is fixedly connected to the top of the side wing protective shell. A linear guide rail is bolted to the adjacent side of the two guide rail mounting bases. A pneumatic slider is slidably connected to the outside of the linear guide rail.

[0016] The above solution combines two guide rail mounting bases, which are firmly fixed to the top of the side protective shell, providing a strong support structure. The linear guide rails on the adjacent sides are connected by bolts, ensuring the stability and accuracy of the guide rails. The sliding connection of the pneumatic slider allows the object to move smoothly on the guide rails, significantly improving the system's flexibility and operational efficiency.

[0017] As a further description of the above technical solution: The bottom of the pneumatic slider is fixedly connected to an electric push rod three. The drive end of the electric push rod three is fixedly connected to a fixed base. The bottom of the fixed base is slidably connected to two sliding guide blocks. The bottom of the fixed base is fixedly connected to a dual-head motor. The bottom of the fixed base is fixedly connected to two limiting plates.

[0018] Through the above scheme, the connection between the electric push rod three at the bottom of the pneumatic slider and the fixed base forms a stable drive system. The two sliding guide blocks slidably connected at the bottom of the fixed base ensure the smoothness and guiding accuracy during the movement. At the same time, the configuration of the dual-head motor provides strong power support and enhances the working efficiency of the system. The setting of the limit plate effectively prevents excessive movement during the movement, ensuring the safety and reliability of operation.

[0019] As a further description of the above technical solution: The output end of the dual-head motor is fixedly connected to a lead screw. One side of the lead screw is rotatably connected inside the limiting plate, and the other side of the lead screw is threadedly connected inside the sliding guide block.

[0020] The above solution involves a fixed connection between the output end of the dual-head motor and the lead screw, which enables the motor's power to be effectively transmitted to the lead screw. The rotational connection between one side of the lead screw and the inside of the limiting plate ensures the flexible movement of the limiting plate, while the threaded connection between the other side of the lead screw and the sliding guide block achieves precise control and stable positioning of the sliding guide block.

[0021] This utility model has the following beneficial effects: 1. In this utility model, a clamping module is installed on the transport module. The clamping module can adapt to round needles of different sizes and shapes, thereby effectively fixing round needles of different models on the clamping module, and has a wide range of applications.
