[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a safety protection device for a hydraulic cutting machine, including a support platform 1, a conveying roller 2 and a fixed frame 3. The support platform 1 is provided with a conveying roller 2, and the top of the support platform 1 is provided with a fixed frame 3. The inner side of the fixed frame 3 is symmetrically provided with a limit rod 5, the outer side of the limit rod 5 is slidably connected with a sliding frame 6, and the bottom of the sliding frame 6 is fixedly connected with a cutting knife 11. A hydraulic lifting mechanism is provided on the top of the sliding frame 6, and a protection mechanism is provided on one side of the sliding frame 6. The product to be cut is placed on the conveying roller 2 on one side of the support platform 1, and the conveying roller 2 drives the product to move toward the other side of the support platform 1. When the conveying roller 2 drives the product to move below the cutting knife 11, the hydraulic lifting mechanism drives the cutting knife 11 to move downward through the sliding frame 6 to automatically cut off the product. During this period, the protection mechanism can separate the space on one side of the cutting knife 11 to play a protective role.

[0020] The hydraulic lifting mechanism includes a cylinder 9 and a connecting frame 10. The cylinder 9 is installed on the top of the fixed frame 3. The output end of the cylinder 9 is connected to the connecting frame 10. The inner side of the connecting frame 10 is fixedly connected to the top of the sliding frame 6. A pressure plate 12 is provided in the middle of the support platform 1. The positions of the cutting knife 11 and the pressure plate 12 are parallel up and down. The height of the top of the cutting knife 11 is parallel to the height of the top of the conveying roller 2. The output end of the cylinder 9 is fixed to the sliding frame 6 through the connecting frame 10. The output end of the cylinder 9 can drive the sliding frame 6 to slide up and down on the outside of the limit rod 5, and the cutting knife 11 is fixed to the bottom of the sliding frame 6, so that the output end of the cylinder 9 can drive the cutting knife 11 to move up and down. The cutting knife 11 moves downward to automatically cut off the product and then moves upward to reset. The conveying roller 2 drives the product to move on the pressure plate 12. During the cutting process, the pressure plate 12 supports the product.

[0021] The protection mechanism includes a rotating rod 7 and a guardrail 8. The bottom of the fixed frame 3 is slidably connected to the guardrail 8 through a slide rail. A rotating rod 7 is symmetrically hinged on one side of the sliding frame 6. The bottom end of the rotating rod 7 is hinged to the inner side of the guardrail 8. The shape of the guardrail 8 is set to a rectangular frame structure. When the sliding frame 6 moves downward, the sliding frame 6 can drive the rotating rod 7 to rotate clockwise. Due to the restriction of the slide rail on the guardrail 8, the rotating rod 7 can drive the guardrail 8 to move linearly on the slide rail, so that the guardrail 8 moves from the inner side of the fixed frame 3 to the outside, which is used to separate the space on the side of the cutting knife 11 to prevent people from directly contacting the cutting knife 11 and improve the safety of the device. When the sliding frame 6 moves upward, the sliding frame 6 can drive the rotating rod 7 to rotate counterclockwise. Due to the restriction of the slide rail on the guardrail 8, the rotating rod 7 can drive the guardrail 8 to move linearly on the slide rail, so that the guardrail 8 moves inward from the outer side of the fixed frame 3 to reset.

[0022] A mounting frame 4 is provided on one side of the support platform 1, a slide groove 14 is provided on the top of the mounting frame 4, and guide plates 15 are symmetrically slidably connected at both ends of the slide groove 14. A driving mechanism is provided on the top of the mounting frame 4, and the driving mechanism includes a bidirectional screw rod 13 and a motor 16. The top of the mounting frame 4 is rotatably connected with the bidirectional screw rod 13, and a motor 16 is installed on one side of the top of the mounting frame 4. The output end of the motor 16 is fixedly connected to one end of the bidirectional screw rod 13, and two bidirectional screw rods are respectively penetrated at both ends of the bidirectional screw rod 13. The top of 13 is threadedly connected to it, the output end of the motor 16 can drive the bidirectional screw rod 13 to rotate on the top of the mounting frame 4, the bidirectional screw rod 13 cooperates with the top thread of the guide plate 15, the slide groove 14 limits the moving trajectory of the guide plate 15, and the bidirectional screw rod 13 can drive the two guide plates 15 to move toward each other along the slide groove 14 in a straight line, so that the bidirectional screw rod 13 drives the two guide plates 15 to approach each other, and then the two guide plates 15 are fitted with the two sides of the product to limit the position of the product, or drive the two guide plates 15 to separate from the product.

[0023] A flange is provided at one end of the motor 16 , and a group of mounting holes are symmetrically provided on both sides of the flange. Bolts are provided inside the mounting holes, and the flange is detachably connected to the top of the mounting frame 4 through the bolts.

[0024] The safety protection device of the hydraulic cutting machine is characterized in that the output end of the cylinder 9 is fixed to the sliding frame 6 through the connecting frame 10. The output end of the cylinder 9 can drive the sliding frame 6 to slide up and down on the outside of the limit rod 5. When the sliding frame 6 moves downward, the sliding frame 6 can drive the rotating rod 7 to rotate clockwise. Due to the restriction of the slide rail on the guardrail 8, the rotating rod 7 can drive the guardrail 8 to move linearly on the slide rail, so that the guardrail 8 moves outward from the inside of the fixed frame 3, which is used to separate the space on one side of the cutting knife 11, avoid direct contact between people and the cutting knife 11, and improve the safety of the device.
