[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0019] like Figures 1 to 5As shown, this utility model discloses a pneumatic blocking device, comprising a cylinder 1, a cylinder positioning plate mounting block 2, two sets of rotating shafts 3, a detection plate 4, a blocking plate 5, a guide rod 6, and a limit switch 7. The top output end of the cylinder 1 is connected to the bottom of the cylinder positioning plate mounting block 2, and the left and right ends of the cylinder positioning plate mounting block 2 are respectively rotatably connected to one end of a set of rotating shafts 3. The bottom front end of the detection plate 4 is evenly connected to the rear ends of the two sets of rotating shafts 3, and the rear end of the cylinder positioning plate mounting block 2 is connected to the bottom front end of the blocking plate 5. A limit switch 7 is provided at the rear end of the blocking plate 5. The detection plate 4 is located in front of the blocking plate 5, and the rear end of the detection plate 4 is connected to the front end of the blocking plate 5 through the guide rod 6. When the cylinder 1 extends, it drives the cylinder positioning plate mounting block 2 to rotate. The mounting block 2, rotating shaft 3, detection plate 4, and blocking plate 5 rise simultaneously; the mounting block 2 and the detection plate 4 are connected by the rotating shaft 3; when a workpiece touches the detection plate 4, the detection plate 4 tilts towards the blocking plate 5 by compressing the spring on the guide rod 6 through the rotating shaft 3, thus triggering the limit switch 7 fixed on the blocking plate and sending a workpiece detection signal; conversely, when no workpiece touches the detection plate 4, the detection plate 4 will not tilt under the action of the spring on the guide rod 6, and the limit switch 7 will not be triggered to send a signal. The installation space requirement is small, making it easy to install, and it combines blocking and detection into one, thereby improving the convenience of the device and enhancing its practicality.
[0020] As a preferred embodiment of the above, a spring is also included. A spring is provided on the outer side of the guide rod 6 so that the detection plate 4 can remain upright when there is no contact with the workpiece, and can tilt backward when subjected to pressure from the workpiece. The presence of the spring ensures that the detection plate can quickly return to its initial position when there is no pressure, thus ensuring the consistency and accuracy of the detection and enhancing its practicality.
[0021] As a preferred embodiment of the above, the spring coefficient is optimized to ensure that it can provide sufficient resistance to stabilize the tilt angle of the detection plate 4 when pressure is applied to the workpiece, and at the same time ensure that the detection plate 4 can quickly return to the upright position after the workpiece is removed; it can provide appropriate resistance when pressure is applied to the workpiece to ensure the stability of the tilt angle of the detection plate and avoid excessive tilting or instability, thus enhancing its practicality.
[0022] As a preferred embodiment of the above, the connection between the detection plate 4 and the blocking plate 5 adopts a precision fit design, which ensures that the two maintain the necessary degree of freedom of movement while avoiding false triggering or signal loss caused by excessive looseness; it ensures the coordinated operation between the detection plate and the blocking plate, avoids jamming or interference problems, improves the working accuracy of the system, and thus enhances its practicality.
[0023] As a preferred embodiment, the position and sensitivity of the limit switch 7 are precisely adjusted to ensure that a signal is accurately emitted when the detection plate 4 is tilted to a predetermined angle, while preventing malfunctions caused by slight vibrations or other external interferences. The precisely adjusted position and sensitivity ensure that the limit switch emits a signal at the appropriate time, improving the accuracy and timeliness of detection, and thus enhancing practicality.
[0024] As a preferred embodiment of the above, the shape and size of the detection plate 4 are optimized to maximize its sensing range and ensure that all workpieces entering the detection area can be accurately captured. The optimized shape and size expand the sensing range of the detection plate, ensuring that no workpiece entering the detection area is missed, improving detection efficiency, and thus enhancing practicality.
[0025] This utility model discloses a pneumatic blocking device. During operation, when the cylinder extends, it simultaneously raises the cylinder positioning plate mounting block, the rotating shaft, the detection plate, and the blocking plate. The cylinder positioning plate mounting block and the detection plate are connected via the rotating shaft. A spring is located on the guide rod between the detection plate and the blocking plate. When a workpiece touches the detection plate, the detection plate, through the rotating shaft, compresses the spring on the guide rod and tilts towards the blocking plate, triggering a limit switch fixed on the blocking plate and sending a workpiece detection signal. Conversely, when no workpiece touches the detection plate, the spring on the guide rod prevents the detection plate from tilting, and the limit switch is not triggered. Before completing the above actions, the device first moves to the desired position.

[0027] In this utility model, the terms "first," "second," and "third" do not represent a specific quantity or order, but are merely used to distinguish names.
[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
