Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1 aims to address the problems of existing feeding devices, such as slow feeding speed, low accuracy, and poor adaptability, which prevent them from conveying different types or specifications of materials during operation. Please refer to [link to example]. Figures 1-7 A feeding device for a CNC machine tool includes a support rod 110, a protective shell 120 fixedly installed at the end of the support rod 110, a drive shaft 210 inserted into the middle of the protective shell 120, a spiral blade 190 fixedly installed on the side of the drive shaft 210, a connecting shaft 211 connected to the side of the drive shaft 210, a fixing shell 150 installed on the side of the connecting shaft 211, an mounting shell 140 installed on the side of the fixing shell 150, and a motor 130 installed between the mounting shell 140 and the fixing shell 150 via a limiting component 350.

[0026] A connecting pipe 160 is fixedly installed on the side of the protective shell 120, and a collection frame 170 is installed on the side of the connecting pipe 160. A support pipe 180 is fixedly installed on the inside of the protective shell 120, and several support pipes 180 are installed at equal intervals. A slot 261 is opened in the middle of the fixed shell 150, and the slot 261 is engaged with the limiting component 350. An installation ring 230 is sleeved on the side of the drive shaft 210, and a fixing ring 220 is sleeved on the side of the installation ring 230.

[0027] When the device is operated, the motor 130 starts, transmitting power through the drive shaft 210, causing the spiral blade 190 fixed to the side of the drive shaft 210 to rotate. The rotational motion of the spiral blade 190 pushes the material forward. The metal layer 330 provides structural strength, the rubber layer 320 reduces wear and noise, and the braided layer 340 increases the friction between the material and the spiral blade 190 to prevent material slippage. The connecting pipe 160 and the collection frame 170 installed on the side of the protective shell 120 are used to guide the flow of material and ensure that the material flows smoothly. The material is fed into the machine tool along a predetermined path. Support tubes 180 are equidistantly installed inside the protective housing 120 to provide support for the material and prevent it from bending or deforming during feeding. The slot 261 in the middle of the fixed housing 150 engages with the limiting assembly 350 to ensure accurate relative positioning between the drive shaft 210 and the motor 130. The mounting ring 230 and the fixing ring 220 are sleeved on the side of the drive shaft 210. The mounting frame 260 and the compression spring 250 in the limiting assembly 350 provide further fixing and cushioning.

[0028] In this embodiment: the rubber layer 320 and braided layer 340 on the spiral blade 190 can reduce vibration and noise during the feeding process and improve the comfort of the working environment. The multi-layer structure of the metal layer 330, rubber layer 320 and braided layer 340 can enhance the durability of the spiral blade 190, enabling it to withstand long-term working loads. The mounting groove 280, connecting spring 290 and locking block 310 provide precise connection and adjustment functions, allowing the feeding device to be fine-tuned according to different processing requirements. The annular array of mounting groove 280, connecting spring 290 and locking block 310 can be quickly configured according to different machine tool models and processing requirements.

[0029] Example 2 aims to improve stability during equipment use. This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 1-7 The limiting component 350 includes a mounting frame 260 fixedly installed in the middle of the mounting ring 230, and a limiting groove 270 is formed in the middle of the mounting frame 260.

A locking groove 200 is provided on the side of the fixing shell 150. The fixing rod 240 is locked in the locking groove 200. An installation groove 280 is provided in the middle of the fixing ring 220. A connecting spring 290 is provided in the middle of the installation groove 280. A locking block 310 is connected to the side of the connecting spring 290. A rotating shaft 300 is fixedly installed in the middle of the installation groove 280.

[0031] A locking block 310 is sleeved on the side of the rotating shaft 300. The locking block 310 engages with the locking groove 261. Several mounting grooves 280, connecting springs 290, and locking blocks 310 are arranged in a circular array. The spiral blade 190 includes a metal layer 330 fixedly connected to the side of the transmission shaft 210. A rubber layer 320 is connected to the side of the metal layer 330. A braided layer 340 is sleeved on the side of the rubber layer 320.

[0032] In this embodiment: the protective shell 120 protects the internal transmission mechanism from external impurities and processing materials, and also prevents operators from accidentally contacting moving parts, thus improving the safety of the working environment. The spiral blade 190 enables the feeding device to effectively push materials through rotational motion, improving feeding efficiency and stability. The structure of the transmission shaft 210, connecting shaft 211, and fixed shell 150 makes it easy to disassemble and replace components such as the spiral blade 190 and motor 130, reducing maintenance complexity and cost. The limiting component 350 and the slot 261 ensure accurate alignment and fixation between the transmission shaft 210 and the motor 130, improving the structural stability of the entire feeding device.
