Description

Technical Field

[0001] The utility model relates to the technical field of silk winding machines, in particular to a multifunctional electric-driven spindle shock absorber. Background Art

[0002] A winding machine is a spinning equipment, which is mainly composed of a fiber-receiving and receiving mechanism, a twisting mechanism, a spindle and a frame. The raw fiber enters the winding machine from the fiber-receiving and receiving mechanism, is processed by the twisting mechanism to form yarn, and the drive motor drives the spindle to rotate. The yarn is arranged by the spindle, thereby producing textile yarn that meets the requirements. An electric-driven spindle refers to a spindle driven to rotate by a drive motor. The spindle is installed at the output end of the drive motor, and the drive motor is fixed to the mounting plate through a shock-absorbing sleeve. The shock-absorbing sleeve mainly consists of a rubber sleeve and a double-headed screw fixed in the rubber sleeve. The top of the double-headed screw passes through the mounting plate, and the top of the double-headed screw passes through the mounting disk of the drive motor. Two nuts are tightened at the top and bottom of the double-headed screw respectively, thereby realizing the installation and fixation of the drive motor. Vibration will be generated during the operation of the drive motor, and the shock absorption of the drive motor is realized by the buffering deformation of the rubber sleeve, thereby realizing the shock absorption during the operation of the spindle.

[0003] When a common electric-driven spindle shock absorber is in use, the vibration generated during the operation of the driving motor is damped by the deformation of the rubber sleeve on the shock-absorbing sleeve. However, there is usually a lack of space inside the rubber sleeve for its own deformation. After long-term use, the stress concentration inside the rubber sleeve is difficult to release, which can easily cause cracks inside the rubber sleeve, thereby affecting the shock-absorbing effect on the spindle. Therefore, the present application provides a multifunctional electric-driven spindle shock absorber to meet the needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a multifunctional electrically driven spindle shock absorber to solve the technical problem that the rubber sleeve usually lacks space for its own deformation, and after long-term use, the stress inside the rubber sleeve is concentrated and difficult to release, which easily causes cracks inside the rubber sleeve, thereby affecting the shock absorbing effect on the spindle.

[0008] Preferably, a rubber ring is fixed to the bottom of the dust cover, and the rubber ring is attached to the top of the mounting plate.

[0009] Preferably, the buffer block is in a fan ring shape.

[0010] Preferably, a fixing block is fixed to the inner wall of the outer sleeve, a rubber airbag is fixed to the side of the fixing block, the rubber airbag is located between two adjacent buffer blocks, a hard tube is embedded on the side of the buffer block close to the rubber airbag, and both ends of the hard tube are respectively connected to the rubber airbag and the cavity.

[0011] Preferably, a central column is provided inside the rubber airbag, an elastic pull strip is fixed to the circumferential surface of the central column, and a side of the elastic pull strip away from the central column is fixedly connected to the inner wall of the rubber airbag.

[0012] Preferably, the plurality of buffer blocks are distributed in a circular array with the center of the inner sleeve as the array center.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, through the arrangement of the inner sleeve, the outer sleeve, the buffer block and the cavity, a buffer block is connected between the inner sleeve and the outer sleeve, and the vibration generated during the operation of the driving motor is damped by the deformation of the buffer block. The cavity provides space for the deformation of the buffer block, and there is no contact between two adjacent buffer blocks, which also provides space for the deformation of the buffer block, thereby preventing the buffer block from cracking, thereby ensuring the shock-absorbing effect on the spindle.

[0017] Through the arrangement of the rubber airbag and the elastic pull strip, the shock absorber oil in the cavity is squeezed when the buffer block is deformed, so that the shock absorber oil enters the rubber airbag and expands the rubber airbag. When the rubber airbag expands, it provides expansion resistance through its own elasticity, and generates expansion resistance again through the pulling of the elastic pull strip. This resistance cooperates with the elasticity of the buffer block itself to prevent the buffer block from being over-extruded and over-deformed, thereby improving the service life of the buffer block. When the buffer block is no longer subjected to vibration force, the rubber airbag returns to its original state under its own elasticity and the pulling of the elastic pull strip, thereby allowing the shock absorber oil to enter the cavity, assisting the buffer block to return to its initial state, improving the rebound ability of the buffer block, and further improving the service life of the buffer block.

[0030] like Figure 1-Figure 5 As shown, the embodiment of the utility model provides a multifunctional electrically driven spindle shock absorber, including a spindle body 1, a driving motor 2 is arranged at the bottom of the spindle body 1, the driving motor 2 is used to drive the spindle body 1 to rotate, the bottom of the driving motor 2 movably penetrates the mounting plate and extends to the bottom of the mounting plate, and also includes:

[0031] The shock-absorbing sleeve 5 includes an inner sleeve 51 and an outer sleeve 52. A dust cover 3 is attached to the mounting plate. The dust cover 3 is used to prevent dust generated during the operation of the winding machine from entering the output shaft position of the driving motor 2, thereby ensuring the smooth operation of the driving motor 2. A plurality of through grooves are opened on the top of the dust cover 3. The outer wall of the outer sleeve 52 is fixedly connected to the inner wall of the through groove. A double-headed screw 4 is fixed to the inner wall of the inner sleeve 51. A plurality of buffer blocks 53 are fixed to the outer wall of the inner sleeve 51. The buffer blocks 53 are rubber blocks that provide shock absorption by their own elastic deformation. The sides of the plurality of buffer blocks 53 It is fixedly connected to the inner wall of the outer sleeve 52, the surface of the mounting plate of the drive motor 2 is fitted with the inner wall of the dust cover 3, the top of the double-headed screw 4 movably penetrates the mounting plate of the drive motor 2 and is threadedly connected with a nut 7, and the nut 7 is pressed on the top of the mounting plate of the drive motor 2, and the bottom of the double-headed screw 4 movably penetrates the mounting plate and is threadedly connected with a nut 2 8, and the nut 2 8 is pressed on the bottom of the mounting plate. A cavity 59 is opened inside the buffer block 53, and the cavity 59 provides space for the deformation of the buffer block 53. While the above structure is used to achieve shock absorption, it also has the effect of dust prevention and has various functions.

[0032] like Figure 3 As shown, in this embodiment, a rubber ring 6 is fixed to the bottom of the dust cover 3, and the rubber ring 6 is attached to the top of the mounting plate. The rubber ring 6 is used to improve the sealing between the dust cover 3 and the mounting plate, thereby improving the sealing ability there.

[0033] like Figure 5 As shown, in this embodiment, the buffer block 53 is in a fan-shaped ring shape, so that the connection between the inner sleeve 51 and the outer sleeve 52 is more stable and reliable.

[0034] like Figure 5 As shown, in this embodiment, a fixing block 54 is fixed to the inner wall of the outer sleeve 52, and a rubber airbag 55 is fixed to the side of the fixing block 54. The rubber airbag 55 is located between two adjacent buffer blocks 53. A hard tube 56 is inlaid on the side of the buffer block 53 close to the rubber airbag 55. The two ends of the hard tube 56 are respectively connected with the rubber airbag 55 and the cavity 59. The fixing block 54 is used to fix the rubber airbag 55 between two adjacent buffer blocks 53. Each buffer block 53 corresponds to a rubber airbag 55. When the buffer block 53 is deformed, the hard tube 56 is used to prevent its deformation from affecting the flow of shock absorber oil. The deformation of the buffer block 53 causes the shock absorber oil in the cavity 59 to enter the rubber airbag 55 through the hard tube 56, causing the rubber airbag 55 to expand. When the rubber airbag 55 expands, it provides expansion resistance through its own elasticity. This resistance cooperates with the elasticity of the buffer block 53 itself to prevent the buffer block 53 from being excessively squeezed and deformed when it is subjected to vibration.

[0035] like Figure 5As shown, in this embodiment, a central column 57 is provided inside the rubber airbag 55, and an elastic pull strip 58 is fixed to the circumferential surface of the central column 57. The side of the elastic pull strip 58 away from the central column 57 is fixedly connected to the inner wall of the rubber airbag 55. There are several elastic pull strips 58, which are used to connect the central column 57 with the rubber airbag 55. When the shock absorber oil enters the rubber airbag 55 to expand it, the elastic pull strip 58 pulls the rubber airbag 55 to provide resistance to the expansion of the rubber airbag 55, and the resistance is matched with the elasticity of the buffer block 53 itself. The rubber airbag 55 is combined to prevent the buffer block 53 from being over-extruded and over-deformed when subjected to vibration, thereby increasing the service life of the buffer block 53. When the buffer block 53 is no longer extruded, the shock absorber oil no longer squeezes the rubber airbag 55, and the rubber airbag 55 recovers to its original state under the pull of its own elasticity and the elastic force of the elastic pull strip 58, so that the shock absorber oil in the rubber airbag 55 flows back into the cavity 59 through the hard tube 56, thereby assisting the buffer block 53 to recover to its original state, improving the rebound ability of the buffer block 53, and further increasing the service life of the buffer block 53.

[0036] like Figure 5 As shown, in this embodiment, a plurality of buffer blocks 53 are distributed in a circular array with the center of the inner sleeve 51 as the array center, and the plurality of buffer blocks 53 jointly dampen the vibration of the drive motor 2 to ensure the damping capability of the drive motor 2 and the spindle body 1.

[0037] like Figure 3 As shown, in this embodiment, the top and bottom of the inner wall of the cavity 59 are curved surfaces, and stress concentration occurs at the bottom and top of the inner wall of the curved cavity 59 and cracking occurs.

[0038] like Figure 5 As shown, in this embodiment, the central axes of the inner sleeve 51 and the outer sleeve 52 coincide with the central axis of the double-headed screw 4, so that the buffer blocks 53 at various locations are evenly stressed, preventing the double-headed screw 4 from tilting and ensuring the smooth installation of the drive motor 2.

[0039] Working principle: fit the rubber ring 6 at the bottom of the dust cover 3 onto the mounting plate, pass the drive motor 2 through the middle of the dust cover 3 through the mounting plate, and fit the mounting plate of the drive motor 2 onto the inner wall of the dust cover 3, respectively tighten the nut 1 7 and the nut 2 8 onto the top and bottom of the double-headed screw 4, thereby achieving the installation and fixation of the drive motor 2, and thus achieving the installation and fixation of the spindle body 1. A plurality of buffer blocks 53 are connected between the inner sleeve 51 and the outer sleeve 52, and the vibration generated during the operation of the drive motor 2 is transmitted to the buffer blocks 5 through the double-headed screw 4. 3. The deformation of the buffer block 53 is used for shock absorption. When the buffer block 53 is deformed, the shock absorber oil in the cavity 59 is squeezed. The shock absorber oil enters the rubber airbag 55 through the hard tube 56, so that the rubber airbag 55 expands. When the rubber airbag 55 expands, it provides expansion resistance through its own elasticity, and then generates expansion resistance again through the pulling of the elastic pull strip 58. This resistance cooperates with the elasticity of the buffer block 53 itself to prevent the buffer block 53 from being excessively squeezed and excessively deformed when it is subjected to vibration, thereby improving the service life of the buffer block 53.

[0040] When the buffer block 53 is no longer subjected to vibration force, the rubber airbag 55 returns to its original state under the pull of its own elasticity and the elastic force of the elastic pull strip 58, so that the shock absorber oil in the rubber airbag 55 flows back into the cavity 59 through the hard tube 56, thereby assisting the buffer block 53 to return to its original state and improving the rebound ability of the buffer block 53, thereby further increasing the service life of the buffer block 53.

In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
