Embodiments of the invention are described below with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of a stepless feed regulating system provided by the invention.

Detailed Description

Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Please refer to fig. 1, which is a schematic structural diagram of a stepless feeding regulation system according to the present invention. The stepless feed regulation system comprises a one-way device 10 and a regulating device 20 connected with the one-way device 10. The one-way device 10 is a prior art device, and the one-way device 10 only has the capability of transmitting one-way torque. It is conceivable that the one-way device 10 is connected to a central shaft 30, and that the central shaft 30 is connected to a link (not shown) which is connected to a feed mechanism (not shown). The stepless feed regulation system should also comprise some other functional modules, such as mounting elements, connecting elements, etc., which should be known to those skilled in the art and therefore will not be described in detail herein.

The adjusting device 20 includes a flange 200, a piston assembly 21 disposed at one side of the flange 200, a driving toothed disc 22 connected to the piston assembly 21 and driven by the piston assembly 21, and a driven toothed disc 23 connected to the one-way device 10. The piston assembly 21 includes a cylinder block 26 bearing-connected to the flange 200, and a piston 27 located within the cylinder block 26. An air inlet hole 28 is formed in the air cylinder seat 26, and compressed air is introduced into the air inlet hole 28. The end of the flange 200 away from the unidirectional device 10 is a driving end, and when the driving fluted disc 22 and the driven fluted disc 23 are embedded, the driving end is used for transmitting torque to the unidirectional device 10. Specifically, the air pressure range of the compressed air introduced into the air inlet 28 is 0.3Mpa to 0.6 Mpa.

The driven fluted disc 23 is further provided with a belt wheel (not shown) and a support bearing (not shown), and the radial force-bearing center of the belt wheel is aligned with the bearing center of the support bearing, so that the service life of the product can be prolonged, and the influence on the service life of the product caused by the excessive offset of the force-bearing center and the bearing center is avoided.

When the driving fluted disc 22 is connected with the driven fluted disc 23, the connection is a face tooth connection. The connection mode of the end face teeth is adopted for connection, the structure is compact, the transmission torque is large, and the transmission precision is high.

The driving fluted disc 22 is connected with a return spring 25. The return spring 25 is arranged so that when compressed air in the air inlet hole 28 is cut off, the driving toothed disc 22 retracts to the initial position, that is, the driving toothed disc 22 is separated from the driven toothed disc 23, and the structure is simple and convenient to implement. In this embodiment, when the compressed air is introduced into the air inlet hole 28, the piston 27 pushes the driving toothed disc 22 to move toward the driven toothed disc 23 until the driving toothed disc 22 is engaged with the driven toothed disc 23, so that the driving end transmits a unidirectional torque to the unidirectional device 10 through the driving toothed disc 22 and the driven toothed disc 23, and the reverse idle rotation does not transmit a torque. When the compressed air of the air inlet hole 28 is cut off, the return spring 25 rebounds to enable the driving fluted disc 22 to move away from the driven fluted disc 23 until the driving fluted disc 22 is separated from the driven fluted disc 23, torque cannot be transmitted in any direction, the traditional feeding mode through a ratchet wheel is changed, the feeding size is controllable, the ratchet wheel does not need to be replaced at regular time, and the cost is saved.

An O-shaped sealing ring 29 is arranged at the air inlet hole 28. The O-shaped sealing ring 29 is better in sealing performance and more convenient to connect, compressed air can be better introduced, and on the premise of good sealing performance, the movement precision of the piston 27 is higher, so that the rotation of the central shaft 30 can be more accurately controlled.

The sealing cover 40 is disposed outside the one-way device 10, and the arrangement of the sealing cover 40 can effectively protect the internal connection structure thereof and reduce the noise generated by the engagement of the driving toothed disc 22 and the driven toothed disc 23 to a certain extent.

Grease (not shown) is filled between the flange 200 and the cylinder block 26, and the grease can well prolong the service life of the bearing between the flange 200 and the cylinder block 26.

Compared with the prior art, the stepless feeding adjusting system provided by the invention is characterized in that one side of the one-way device 10 is connected with an adjusting device 20, the adjusting device 20 comprises a flange plate 200, a piston assembly 21, a driving fluted disc 22 and a driven fluted disc 23, the piston assembly 21 drives the driving fluted disc 22 to move by introducing compressed air, so that the driving fluted disc 22 and the driven fluted disc 23 are embedded to finish the transmission of one-way torque, the driving fluted disc 22 and the driven fluted disc 23 are separated by cutting off the compressed air and a return spring 25 to stop the transmission of the torque, the traditional feeding mode through a ratchet wheel is changed, the feeding with any size can be realized, the ratchet wheel does not need to be replaced at regular time, and the cost is saved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
