Detailed Embodiment

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0018] Referring to Figure 1-2 as shown, a line blocking mechanism includes a base 1 and a pair of fixed plates 11. The pair of fixed plates 11 are installed on the base 1 and symmetrically distributed. A rotating shaft 12 is rotatably connected to the pair of fixed plates 11. Two symmetrically distributed rotating plates 2 are connected to the rotating shaft 12. A connecting shaft 21 is commonly rotatably connected to the ends of the two rotating plates 2 away from the rotating shaft 12. A collision arm 22 is connected to the connecting shaft 21. Two blocking wheels 23 are rotatably connected to the upper end of the collision arm 22 through a pin shaft. A control mechanism is provided on the base 1 for controlling the lifting of the rotating plate 2, and a buffer mechanism is provided on the rotating plate 2 for playing a collision buffering role for the collision arm 22.

[0019] In this embodiment, the control mechanism includes a cylinder 3. The cylinder 3 is installed on the base 1. The movable end of the cylinder 3 is connected with a U-shaped connecting piece 32. The two ends of the connecting piece 32 far away from the cylinder 3 are rotatably connected with guide shafts 33. The two ends of the guide shafts 33 are coaxially connected with lifting wheels 35. The wheel surfaces of the two lifting wheels 35 are respectively in contact with the bottom surfaces of the two rotating plates 2.

[0020] In this embodiment, the buffer mechanism includes a mounting plate 4 and a buffer 41. The mounting plate 4 is installed between the two rotating plates 2. The buffer 41 is installed on the mounting plate 4. The buffer rod on the buffer 41 penetrates through the mounting plate 4 and is rotatably connected with a transition block 42. A rotating groove 43 is formed at the lower end of the collision arm 22. One end of the transition block 42 far away from the buffer rod is rotatably connected with the rotating groove 43 of the collision arm 22 through a pin shaft. A groove 24 is formed at the bottom of the rotating plate 2 close to one side of the rotating shaft 12.

[0021] In this embodiment, a guide bar 31 is installed on the base 1. A guide wheel 34 is coaxially connected to the middle position of the guide shaft 33. The guide wheel 34 is in rolling connection with the guide bar 31, so that the movable rod of the cylinder 3 does not bear the vertical pressure, thereby prolonging the service life of the cylinder 3.

[0022] Working process and principle:

[0023] During the working process, when it is necessary to block the transport piece on the automatic production line, the cylinder 3 will be activated to push the connecting piece 32 to slide forward. The lifting wheel 35 moves forward along the guide bar 31 under the push of the cylinder 3. During this process, the lifting wheel 35 will slide out of the groove 24 of the rotating plate 2, lift the rotating plate 2, so that the blocking wheel 23 is lifted upward to the transport path to block the transport piece. At the moment when the transport piece is blocked by the blocking wheel 23, the collision impact force will be transmitted to the buffer 41 through the collision arm 22 and the transition block 42, buffering the impact force and avoiding acting on the cylinder 3, thus prolonging the service life of the cylinder 3. When it is necessary to release the block, control the cylinder 3 to pull the lifting wheel 35 back to slide, and the whole rotating plate 2 will turn downward to lower the height of the blocking wheel 23 to realize the release.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
