[0019] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0020] The embodiment of the present invention provides a pneumatically controlled stepping conveyor roller, which can solve the problem in the related art that the motor-driven roller requires the coordination of electrical appliances and machinery, and is complex to control, high in cost, and difficult to maintain.

[0021] See also Figure 1 As shown, a pneumatic stepping conveyor roller conveyor provided by an embodiment of the present invention, the rollers on the conveyor roller conveyor frame are all linked by a chain 12, a gear 8 is installed at one end of any roller on the conveyor roller conveyor frame, the gear 8 has a one-way rotating ratchet 7 inside, a rack 6 and a sliding guide rail 13 are installed below the gear 8, the rack 6 is connected to the piston rod of the cylinder 3, the cylinder 3 is fixed to the roller conveyor frame by a fixed block, the air inlet of the cylinder 3 is respectively equipped with a cylinder front cavity air inlet regulating valve 9 and a cylinder rear cavity air inlet regulating valve 10, and the rear end reversing valve 4 and the front end reversing valve 5 are respectively installed at both ends of the rack 6. The purpose of material conveying is achieved by utilizing the expansion and contraction of the cylinder 3 to drive the one-way rotating ratchet 7 to rotate, which is suitable for large-scale, slow-paced flat material conveying on site, and the entire drive control is completed by mechanical parts and pneumatic components, which reduces the manufacturing cost, facilitates fault diagnosis and maintenance, has high reliability, is convenient for maintenance, and is low in cost.

[0022] Specifically, the cylinder front chamber air intake regulating valve 9 and the cylinder rear chamber air intake regulating valve 10 are throttling speed regulating valves, which are used to adjust the flow rate and flow rate of the medium; the rear end reversing valve 4 and the front end reversing valve 5 are pneumatic travel switches, which are used to use the collision of mechanical moving parts to move their contacts to connect or disconnect the control circuit and achieve certain control purposes; the pneumatic reversing valve 2 is used to cut off, distribute and change the flow direction of the medium; the control air valve 1 is used to control the gas in and out of the cylinder 3.

[0023] During operation, open the control air valve 1, the pneumatic reversing valve 2 starts to work, and the compressed air enters the front chamber of the cylinder 3 through the cylinder front chamber air intake regulating valve 9. The piston rod of the cylinder 3 drives the rack 6 to move to the left, and the gear 8 rotates clockwise at the same time. Since the unidirectional rotating ratchet 7 rotates unidirectionally, the gear 8 is idling at this time, and the stepping conveyor roller is in a stopped state.

[0024] When the piston rod of cylinder 3 drives rack 6 to move to the left and touches the rear reversing valve 4, pneumatic reversing valve 2 starts to reverse, and compressed air enters the rear chamber of cylinder 3 through the air inlet regulating valve 10 of the rear chamber of cylinder 3. The piston rod of cylinder 3 drives rack 6 to move to the right, and gear 8 rotates counterclockwise at the same time. The one-way rotating ratchet 7 inside gear 8 also rotates at the same time, driving the coaxial sprocket 11 to rotate, and the sprocket 11 drives the chain 12 to run to the right. Since all rollers are connected together, the rollers run to the right, driving the materials to move to the right. When rack 6 moves to the right and touches the front reversing valve 5, pneumatic reversing valve 2 starts to reverse, and rack 6 returns. This cycle repeats.

[0025] In some optional embodiments, the other side of the roller support is symmetrically provided with the one-way rotating ratchet 7, the gear 8, the cylinder 3, the rack 6, the cylinder front chamber air intake regulating valve 9, the cylinder rear chamber air intake regulating valve 10, the pneumatic reversing valve 2, the front reversing valve 5, the rear reversing valve 4 and the control air valve 1. By symmetrically arranging the above-mentioned mechanisms on both sides of the roller support, when the piston rod of the cylinder 3 on one side drives the rack 6 to move to the left (contract), the piston rod of the cylinder 3 on the other side drives the rack 6 to move to the right (extend), so that the conveying roller can continuously maintain the forward state, thereby improving the working efficiency.

[0026] Furthermore, the control valve 1 signals on both sides are connected to the controller, and the controller includes a module for controlling the opening frequency of the control valve 1. The controller can control the regular operation of the mechanisms on both sides to ensure that the conveyor roller keeps working continuously and cyclically.
