Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 - Figure 5As shown, the embodiment provides a high-efficiency vibration reduction circular knitting machine, which comprises a circular knitting machine body 1, which can be a common single-face circular knitting machine commonly used on the market, and is prior art. The lower side of the circular knitting machine body 1 is fixedly connected with a plurality of piston frames 2. The inner walls of the plurality of piston frames 2 are all slidably connected with piston blocks 3. The upper side of the plurality of piston blocks 3 is fixedly connected with buffer springs 4 fixedly connected with the piston frames 2. A plurality of damping holes 5 are formed in one side of the inner wall of the piston frame 2.

[0026] Please refer to Figure 2 The lower side of the plurality of piston blocks 3 is fixedly connected with a mounting plate 11. The lower side of the plurality of mounting plates 11 is fixedly connected with a protective pad 12. The bottom of the piston block 3 is installed through the mounting plate 11. The protective pad 12 can protect the lower side of the mounting plate 11 to avoid damage to the ground.

[0027] Please refer to Figure 2 A plurality of guide grooves 13 are formed in one side of the piston frame 2. The inner walls of the plurality of guide grooves 13 are all slidably connected with L-shaped guide blocks 14 fixedly connected with the baffle 8. When the baffle 8 moves, the L-shaped guide blocks 14 slide in the guide grooves 13 to limit the upper side of the baffle 8 to ensure the stability of the baffle 8 when plugging the damping holes 5.

[0028] A plurality of adjusting grooves 6 are formed in one side of the plurality of piston frames 2. The inner walls of the adjusting grooves 6 are slidably connected with control blocks 7. The upper side of the control block 7 is fixedly connected with a baffle 8 matched with the plurality of damping holes 5. A locking mechanism 9 is arranged between the control block 7 and the adjusting groove 6. The one side of the plurality of piston frames 2 is provided with a supporting assembly 10.

[0029] Please refer to Figure 2 The locking mechanism 9 comprises a locking pin 901 threadedly connected on one side of the control block 7, and a locking hole 902 formed in one side of the inner wall of the adjusting groove 6 and matched with the locking pin 901. The locking pin 901 moves on the control block 7 to be inserted between the corresponding locking hole 902, so that the position of the baffle 8 can be changed to achieve different degrees of shielding of the plurality of damping holes 5.

[0030] Please refer to Figure 2 and Figure 4 A plurality of calibration grooves 15 matched with the plurality of locking holes 902 are formed in one side of the plurality of piston frames 2. One side of the plurality of control blocks 7 is fixedly connected with a calibration strip 16 matched with the calibration groove 15. When the control block 7 moves, the calibration strip 16 is aligned with the calibration groove 15, so that the overlapping state between the locking pin 901 and the locking hole 902 can be known, improving the convenience of operation.

[0031] Please refer to Figure 3 and Figure 4The supporting assembly 10 comprises a pushing frame 101 fixedly connected to one side of the piston frame 2, a high-strength lead screw 102 rotatably fitted to the inner wall of the pushing frame 101, a driving motor 103 fixedly connected to the upper side of the pushing frame 101 and fixedly connected with the high-strength lead screw 102, and a bearing block 104 slidably fitted to the inner wall of the pushing frame 101 and threadedly fitted with the high-strength lead screw 102. After the equipment is used, if it is not used for a long time, it is difficult to start the driving motor 103 to drive the high-strength lead screw 102 to rotate, so that the bearing block 104 moves downward in the pushing frame 101, and the bearing block 104 is abutted with the mounting plate 11, so that the buffer spring 4 is no longer subjected to pressure, thereby avoiding the stress condition of the buffer spring 4 in non-use, and the service life of the buffer spring 4 is improved to a certain extent.

[0032] Please refer to Figure 2 A limiting hole 17 is formed in one side of the pushing frame 101, and a limiting block 18 fixedly connected with the bearing block 104 is slidably fitted to the inner wall of the limiting hole 17. When the bearing block 104 moves, the limiting block 18 moves in the corresponding limiting hole 17, so as to guide the bearing block 104 to move stably.

[0033] The implementation principle of the vibration-damping and efficient circular knitting machine is as follows: when the circular knitting machine body 1 is started, the mounting plate 11 is first placed stably on the ground, and vibration is transmitted to each piston frame 2. Due to the sliding fit between the piston block 3 and the piston frame 2, the piston block 3 moves up and down relative to the piston frame 2 under the action of vibration, thereby compressing or stretching the buffer spring 4. The buffer spring 4 absorbs and stores the mechanical energy of vibration by using the elastic deformation of itself, and then releases the energy by rebounding, thereby playing a role in preliminarily buffering vibration, so that the vibration amplitude transmitted to the ground and other support structures is reduced to a certain extent. In the moving process of the piston block 3, the air in the piston frame 2 is discharged or sucked through the damping holes 5, thereby realizing the damping effect.

[0034] When different materials are processed, the control block 7 in the adjusting groove 6 is adjusted to move, thereby driving the baffle 8 to move correspondingly. By blocking the corresponding damping holes 5 by the baffle 8, the difficulty of air discharge through the damping holes 5 is changed, and the damping size generated by air flow is also changed. For example, when the baffle 8 blocks more damping holes 5, the air discharge or suction is blocked, the resistance of the piston block 3 during movement is increased, the rapid movement of the piston block 3 is more effectively inhibited, the vibration energy is further consumed, and the overall damping effect is enhanced. Conversely, when the baffle 8 blocks less, the air flow is smooth, the damping is small, and the damping is relatively softer. In this way, the damping degree can be flexibly adjusted according to actual needs to adapt to different fabric processing and improve the application range.

[0035] When the device is not used for a long time after use, the high-strength screw rod 102 can be driven to rotate by starting the driving motor 103, so that the bearing block 104 moves downward in the pushing frame 101, and the bearing block 104 is in abutment with the mounting plate 11, so that the buffer spring 4 is no longer subjected to pressure, thereby buffering the stress condition of the buffer spring 4 when not in use, and improving the service life of the buffer spring 4.

[0036] The basic principle and main features of the utility model and the advantages of the utility model are shown and described above, and the skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and the description in the specification are only to illustrate the principle of the utility model, and various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed, and the scope of protection of the utility model is defined by the appended claims and their equivalents.
