Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0023] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0024] like Figure 1-6As shown, one embodiment of this utility model relates to a pneumatic propulsion device for a roller bed line, including a support frame 10 for supporting and fixing the overall device. The support frame 10 is rectangular, and a cylinder assembly 20 is fixedly mounted at one end of the support frame 10. The end of the cylinder piston rod 21 is connected to a carriage assembly 30 via a floating joint 22. A push rod 40 is hinged to the top of the carriage assembly 30, and a guide wheel 60 is rotatably connected to the push rod 40. A guide member 11 corresponding to the guide wheel 60 is fixedly mounted on the side wall of the support frame 10. The guide member 11 has a guide groove 111 facing the guide wheel 60. The guide wheel 60 slides or rolls with the guide groove 111. A guide block 12 is provided at one end of the component 11 near the cylinder assembly 10. The guide block 12 is provided with an inclined guide slope 121 corresponding to the starting end of the guide groove 111. When the piston rod 21 is fully retracted, the guide wheel 60 is located at the top of the guide slope 121. When the cylinder piston rod 21 is extended, the guide wheel 60 moves down along the guide slope 121 and enters the guide groove 111, driving the push rod 40 to rotate around the hinge shaft 50. This causes the push head 44 at the end of the push rod 40 to extend out of the upper end face of the support frame 10. The trolley assembly 30 moves linearly within the support frame 10, thereby driving the push rod 40 to move. The push head 44 at the end of the push rod 40 abuts against the material and pushes the material to the designated position.
[0025] One embodiment relates to a pneumatic propulsion device for a roller bed line. The trolley assembly 30 includes a chassis 32 and wheels 31 rotatably mounted on the bottom of the chassis 32. A guide rail 13, which cooperates with the wheels 31, is fixedly installed within the support frame 10. The guide rail 13 constrains the movement trajectory of the wheels 31, allowing the trolley assembly 30 to move linearly along the frame axis with the cooperation of the wheels 31 and the guide rail 13. The end of the piston rod 21 is connected to the chassis 32 via a floating joint 22, which facilitates the smooth movement of the wheels 31 within the guide rail 13 and prevents the wheels 31 from jamming with the guide rail 13, thereby ensuring the stability of the trolley assembly 30's movement within the support frame 10. In an exemplary example, the wheels 31 are double-row rollers, and the guide rail 13 is a U-shaped component symmetrically fixed to the side wall of the support frame. The guide rail 13 is parallel to the guide groove 111, and the opening of the guide rail 13 faces the wheels 31. The spacing of the inner sidewall of the guide rail 13 matches the wheel spacing of the double-row rollers.
[0026] In one embodiment, a pneumatic propulsion device for a roller bed line is provided. The top of the chassis 32 is provided with two ears 33 spaced parallel to each other. The ears are provided with hinge portions 331. The middle section of the push rod 40 is provided with a through hinge hole 43. The hinge hole 43 is located between the two ears 33 and corresponds to the hinge portion 331. The push rod 40 is hinged to the ears 33 through a hinge shaft 50.
[0027] One embodiment relates to a pneumatic propulsion device for a rolling mill line. A pusher head 44 extends obliquely from the end of a pusher rod 40 away from the cylinder assembly 20. Preferably, the pusher head 44 is obliquely downward along the direction of travel of the piston rod 21. The axis of the pusher head 44 forms an acute angle with the axis of the pusher rod 40. A limiting block 41 is fixedly provided at the end of the pusher rod 40 near the cylinder assembly 20. The limiting block 41 has a limiting surface 42 parallel to the end plane of the pusher head 44 at its end away from the cylinder assembly 20. The chassis 32 corresponds to the limiting block 41. A limiting groove 321 is provided, and the side wall of the limiting groove 321 away from the cylinder assembly 20 is a stop surface 3211. When the piston rod 21 extends and pushes the trolley assembly 30 forward, and the guide wheel 60 moves from the guide ramp 121 to the guide groove 111, the limiting surface 42 and the stop surface 3211 abut against each other to form a rigid stop, preventing the push rod 40 from continuing to rotate around the hinge axis 50. This ensures the stability of the relative position of the push rod 40 with respect to the support frame 10, allowing the push rod 40 to provide a stable force to the material and push the material to the designated position. Preferably, a buffer pad 45 is fixedly provided at the end of the push head 44. The buffer pad 45 is made of a non-rigid material, such as rubber or silicone, which can effectively reduce the impact force of the push rod 40 on the material, avoid damage to the material or the propulsion device, and help extend the service life of the propulsion device.
[0028] When the piston rod 21 is fully retracted, the guide wheel 60 is at the top of the guide ramp 121, the axis of the push rod 40 is approximately parallel to the axis of the support frame, and the push head 44 is housed inside the support frame 10. When the piston rod 21 extends, the guide wheel 60 moves downward along the guide ramp 121, driving the push rod 40 to rotate around the hinge axis 50, and the push head 44 moves away from the chassis 32. When the guide wheel 60 moves to the bottom of the guide ramp 121, the limiting surface 42 of the push rod 40 and the limiting groove 321 stop. The stop surface 3211 abuts against and stops, preventing the push rod 40 from rotating further. At this time, the push head 44 extends out of the upper end face of the support frame 10, so that the push head 44 at the end of the push rod 40 extends out of the upper end face of the support frame 10. As the piston rod 21 continues to extend, the guide wheel 60 moves along the guide groove 111. Through the extension of the piston rod 21, the trolley assembly 30 and the push rod 40 are driven to move axially along the support frame, so that the push head 44 applies force to the material on the material's path and pushes the material to the designated position.
[0029] One embodiment relates to a pneumatic propulsion device for a rolling mill line. The cylinder assembly 20 has a magnetic sensor 231 and an air pipe connector 232 mounted on its cylinder body 23. The magnetic sensor 231 detects the position of the piston in the cylinder, enabling precise control of the piston stroke. The cylinder body 23 is connected to an external gas pipeline via the air pipe connector 232. Preferably, the gas pipeline is connected to a solenoid valve (not shown) and a pressure sensor (not shown). The solenoid valve and pressure sensor are connected to a control device (not shown). The pressure sensor monitors the air pressure inside the cylinder in real time and transmits the signal to the control device. The control device adjusts the opening of the solenoid valve based on the real-time detection value of the pressure sensor. When the detected air pressure deviates from a set threshold, the air intake is automatically adjusted to maintain a stable air pressure inside the cylinder. During the operation of the piston rod 21, the pressure sensor monitors the air pressure inside the cylinder in real time. When the air pressure is lower or higher than the set value, the controller adjusts the air pressure inside the cylinder by controlling the opening and closing of the solenoid valve to ensure stable operation of the pneumatic propulsion device.
[0030] When piston rod 21 needs to extend, the control device opens the solenoid valve, allowing air to enter the cylinder through the air inlet and drive the piston. Piston rod 21 pushes trolley assembly 30 along guide rail 13, which in turn drives push rod 40 to extend and contact the material, propelling the material to the designated position.
[0031] The pneumatic propulsion device for roller bed lines provided by this utility model, compared with the prior art, drives the trolley assembly through the piston rod of the cylinder assembly, the hinged arrangement of the trolley assembly and the push rod, and the cooperative arrangement of the guide wheel with the guide groove and the guide slope. When the piston rod extends, the push head at the end of the push rod extends out of the upper surface of the support frame and pushes the material to the designated position, achieving stable material propulsion. The propulsion device has a simple and compact structure, is easy to install and maintain, and can be flexibly adapted to the auxiliary propulsion of materials in automobile production lines. The cylinder acts quickly, which can improve the response speed of the propulsion device. The pneumatic components are relatively inexpensive, which can effectively reduce maintenance costs. Through the setting of magnetic sensors, solenoid valves and air pressure sensors, the air pressure in the cylinder can be effectively maintained to stabilize, increasing the operational stability of the trolley assembly and the push rod, and achieving precise and stable material propulsion.
[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
