It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In order to explain the technical means of the present invention, the following description will be given by way of specific examples.

As shown in fig. 1-3, the pneumatic intermittent driving device provided in this embodiment includes a horizontal cylindrical box 1, the top of the cylindrical box 1 is communicated with an inlet pipe 2, the bottom of the cylindrical box 1 is communicated with an outlet pipe 3, a piston 31 and a baffle ring 32 are arranged in the outlet pipe 3, a driving rod 33 is arranged at a center axis position of the piston 31 downward, the driving rod 33 is a diameter-variable rod, an upper section diameter is smaller than a lower section diameter, an inner diameter of the baffle ring 32 is matched with an upper section diameter of the driving rod, an upper section of the driving rod 33 upwardly penetrates through the baffle ring 32 and is fixed to the bottom of the piston 31, a spring 34 is further arranged between the piston 31 and the baffle ring 32, a rotating member 4 is installed in the cylindrical box 1, a driving mechanism 5 for driving the rotating member to rotate in the cylindrical box is arranged outside the cylindrical box 1, a fan-shaped member 41 is arranged in the middle of the rotating member 4, two cylinder 42 symmetry in position, the diameter and the 1 internal diameter of cylinder box of cylinder 42 match, cylinder box inner wall is hugged closely and has sealed effect to the cambered surface of fan-shaped spare 41, the bottom position of 1 both sides of cylinder box is opened there is circular

arc gas vent

11, 11 width less than or equal to cylinder 42 thickness in circular arc gas vent, and 11 length in circular arc gas vent are unanimous with the breach arc length of the fan-shaped breach of cylinder 42, the angle hypothesis of fan-shaped breach is alpha, and the fan-shaped angle of fan-shaped spare cross section is beta, beta 2 alpha. As an example, β is 120 ° and α is 60 °.

The working process is as follows:

the rotating part rotates as shown in fig. 4, two small circles at the lower part in the figure represent the positions of the circular arc exhaust ports of the cylindrical box body, one circle at the periphery is the outer wall of the cylindrical box body, the positions of the air inlet pipe at the upper part, the air outlet pipe at the lower part and the circular arc exhaust ports are not changed, the rotating part at the inner part rotates, the black sector blocks shown in the figure are the cross sections of the sector parts, the sector grid shadows are the cross sections of the cylindrical parts with sector gaps, and the black blocks and the grid shadows synchronously rotate. In the rotating process, as long as the black block blocks the air inlet pipe above, the air inlet pipe is closed at the moment; in the rotating process, as long as the black block does not block the air outlet pipe below, the air outlet pipe is communicated with the interior of the cylindrical box body; in the rotating process, if the grid shadow (including the black block part, the same below) completely blocks the arc exhaust port, the outside of the cylindrical box body is closed off from the inside of the cylindrical box body, and otherwise, the cylindrical box body is switched on.

Therefore, when the black block does not block the air inlet pipe and the air outlet pipe, and the grid shadow completely blocks the arc exhaust port, the inlet air of the air inlet pipe can be output from the air delivery pipe at the moment, and the piston is driven to move downwards.

When the air inlet pipe is blocked by the black block, but the air outlet pipe is not blocked by the black block, and the arc exhaust port is not completely blocked by the grid shadow, at the moment, the piston moves upwards under the action of the spring, and the air in the cylindrical box body is exhausted from the arc exhaust port.

In fig. 4, (a) is an initial state, the sector-shaped notch of the cylindrical member is just aligned with the arc exhaust port of the cylindrical box body, and at this time, the inlet pipe cannot intake air; in the process of switching from the state (a) to the state (b), the inlet pipe cannot intake air; in the process of switching from the state (b) to the state (c), the arc exhaust port is sealed, the air enters the inlet pipe, the air outlet pipe is communicated with the interior of the cylindrical box body, so that the air inlet pipe can convey air to the air conveying pipe, and the piston and the driving rod move downwards; in the process of switching from the state (c) to the state (d), the arc exhaust port is sealed, the air outlet pipe is sealed and closed, and the position of the piston is kept unchanged; in the process of switching from the state (d) to the state (e), the arc exhaust port is sealed, the air inlet pipe is communicated with the air outlet pipe again, but the position of the piston is still unchanged at the moment because the air inlet pressure of the inlet pipe is unchanged; and (c) in the process of turning from the state (d) to the state (b), the arc exhaust port is opened, the air inlet pipe is sealed, the air in the cylindrical box body is exhausted from the arc exhaust port at the moment, and the piston and the driving rod move upwards under the action of the spring to return to the initial position. Therefore, during the rotation process of the rotating member, the inflation process is carried out from the state (b) to the state (c), the driving rod moves downwards, the maintenance process is carried out from the state (c) to the state (e), the exhaust process is carried out from the state (e) to the state (b), and the driving rod moves upwards and returns, so that the intermittent reciprocating driving is realized.

As a specific implementation manner of the driving mechanism 5, the driving mechanism 5 includes a driving motor 51, a first pulley 52 and a second pulley 53, the first pulley 52 and the second pulley 53 are located on a side wall of the cylindrical box, the first pulley 52 is linked with a central axis of the rotating member, a transmission belt 54 is sleeved between the first pulley and the second pulley, and an output shaft of the driving motor 51 is linked with the second pulley 53. The driving motor drives the second belt wheel to rotate, the second belt wheel drives the first belt wheel to rotate through the transmission belt, and the first belt wheel drives the rotating part to rotate.
