[0048] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0049] Example 1

[0050] like Figures 1-4 The shown material-stopping mechanism includes:

[0051] Guide sleeve seat 4, which is used to fix on the frame, and has a guide slide cavity 41 inside;

[0052] The material stop assembly 12 has its rear end movably inserted into the guide slide cavity 41;

[0053] Cylinder 1 is installed at the rear end of guide sleeve seat 4. The output end of cylinder 1 is connected to the baffle assembly 12 and is used to drive the baffle assembly 12 to slide inside the guide sleeve seat 4.

[0054] The cylinder 1 has a high-pressure gear and a low-pressure gear. Different gears can apply different amounts of force to the baffle assembly 12, and the cylinder 1 controls the switching of gears through a circuit.

[0055] When the cutting machine needs to feed material, cylinder 1 actually uses a high-pressure setting to limit the length of material movement, thereby ensuring that the material is processed by the cutting machine to the required length.

[0056] When the cutting machine feeds in the material and makes the material abut against the material stop assembly 12, the cutting machine clamps the material and prepares to perform the cutting action. At this time, the cylinder 1 switches to the low pressure position.

[0057] When the cutting machine performs the cutting action, a large radial force is applied to the material by the cutter of the cutting machine. At the same time, the cutter has a certain volume, and during the cutting process, the cutter further presses the material against the material blocking assembly 12.

[0058] At this time, the material blocking assembly 12 bears the axial pressure applied by the material and the friction generated when the material is pushed. After long-term use, the material blocking assembly 12 is easily deformed, affecting the processing accuracy. Or the material blocking assembly 12 is broken, affecting the service life of the material blocking assembly 12.

[0059] In the technical solution, the material blocking assembly 12 comprises:

[0060] The hinge seat 3 is provided with a guide rod portion 32 at the rear end, and a hinge position 31 is opened at the front end. The guide rod portion 32 is connected with the push rod 11 of the air cylinder 1, so that the air cylinder 1 can drive the hinge seat 3 to move in the guide sleeve seat 4.

[0061] The material blocking piece 2 is hinged in the hinge position 31 through the flange bearing 26, and is used for blocking the material.

[0062] The spring 6 is arranged on the guide sleeve seat 4, and one end of the spring 6 is connected with the material blocking piece 2, and is used for driving the material blocking piece 2 to reset.

[0063] Since the material blocking piece 2 is hinged on the hinge seat 3, when the cutting machine performs the cutting action and the material transmits the force to the material blocking piece 2, the material blocking piece 2 swings, thereby reducing the fracture stress of the material blocking piece 2. With the movement of the material blocking piece 2, the material blocking piece 2 moves away from the material, so that the pressure between the material blocking piece 2 and the material is reduced, thereby reducing the friction force of the material blocking piece 2 from the material, and facilitating the cut material to fall from the processing position.

[0064] As shown in Figures 1-4 The guide sleeve seat 4 is provided with a through hole 43.

[0065] The hinge seat 3 is formed with a positioning hole 34;

[0066] When the through hole 43 is aligned with the positioning hole 34, the positioning connecting piece 5 is inserted into the positioning hole 34 through the through hole 43, and the direction of the hinge seat 3 in the guide sleeve seat 4 is fixed. When the hinge seat 3 rotates in the guide sleeve seat 4, the working state is affected.

[0067] Further, the guide sleeve seat 4 is formed with a limiting groove 42, and the through hole 43 is arranged at the bottom of the limiting groove 42; and the through hole 43 is a strip-shaped hole, and the length direction of the through hole 43 is consistent with the length direction of the limiting groove 42.

[0068] The positioning connecting piece 5 comprises a limiting head 51 and a connecting rod 52, the limiting head 51 is movably arranged in the limiting groove 42, and the connecting rod 52 is arranged in the through hole 43 and the positioning hole 34.

[0069] As shown in the figure Figure 4 The material blocking piece 2 is formed with a connecting groove 27, the connecting groove 27 is provided with a reset connecting piece 61, and one end of the spring 6 is connected with the reset connecting piece 61.

[0070] The connecting rod 52 extends out of the limiting head 51, and the other end of the spring 6 is connected with the limiting head 51.

[0071] When cutting off the material, the spring 6 can drive the material blocking piece 2 to quickly reset to ensure that the next material blocking action can be normally performed.

[0072] Further, the hinged end 22 is further provided with a connecting groove 28, and the connecting groove 28 is provided with a stroke limiting portion 29. When the material blocking piece 2 is in the resetting process, the stroke limiting portion 29 can abut against the hinged seat 3, thereby preventing the material blocking piece 2 from continuing to be driven to rotate by the spring 6, so as to limit the position of the material blocking piece 2 after resetting.

[0073] Specifically Figure 4 As shown, the material blocking piece 2 is formed with a material blocking head 21 and a hinged end 22, wherein the hinged end 22 is hinged with the hinged seat 3.

[0074] The material blocking head 21 is protrudingly formed on one side of the hinged end 22, so that the material blocking piece 2 is L-shaped, and the material blocking piece 2 forms an L-shaped lever.

[0075] The connecting groove 27 is arranged on the other side of the hinged end 22, so as to be more convenient for driving the material blocking piece 2 to reset.

[0076] Further, the material blocking head 21 is formed with an abutting surface 23, and the abutting surface 23 is formed with a material returning curved surface 24 on both sides. The abutting surface 23 is used for abutting against the material to limit the material feeding.

[0077] When the cutting machine performs the cutting action, the material blocking piece 2 rotates, so that the material returning curved surface 24 contacts the material, thereby further reducing the friction force generated between the material blocking head 21 and the material.

[0078]

Embodiment Two

[0079] As shown Figure 5 The embodiment and the embodiment one are basically the same, and the difference lies in that:

[0080] The material blocking piece 2 is formed with a connecting groove 27, the connecting groove 27 is provided with a reset connecting piece 61, and one end of the spring 6 is connected with the reset connecting piece 61.

[0081] The guide sleeve seat 4 has a protruding fixing part 44, and the other end of the spring 6 is connected to the fixing part 44.

[0082]

Example 3

[0083] like Figure 6 As shown, this embodiment is basically the same as Embodiment 1, except that:

[0084] The stopper 2 is hinged to the hinge position 31 of the hinge seat 3 by the limit bolt 25;

[0085] A coil spring 7 is sleeved on the outside of the limiting bolt 25. One end of the coil spring 7 is connected to the stop head 21, and the other end of the coil spring 7 is connected to the hinge seat 3.

[0086]

Example 4

When the guide rod portion 32 is movably inserted into the guide cavity 41, the flattened portion 33 fits against the inner wall of the guide cavity 41 to prevent the guide rod portion 32 from rotating within the guide cavity 41, thus fixing the position of the hinge seat 3 within the guide sleeve seat 4.
