All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0021] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, a safety cutting machine includes a frame 1, a cutting mechanism and a protective mechanism, with the frame 1 arranged at the front and rear.

[0022] The cutting mechanism is located at the rear of the top of the frame 1. The cutting mechanism includes a first protective cover 201 and a blade 202. The first protective cover 201 is rotatably mounted on the top of the frame 1 via a control assembly. The control assembly includes two rotating rods 203, two connecting brackets 204, and a counterweight 205. The two rotating rods 203 are rotatably connected to the top of the frame 1 via torsion springs. The connecting brackets 204 are fixed to the top of the rotating rods 203. The counterweight 205 is rotatably connected between the two connecting brackets 204. The first protective cover 201 is fixed to the front end of the counterweight 205. A control rod 207 is fixed to one side of the first protective cover 201. The blade 202 is rotatably mounted inside the first protective cover 201 via a drive assembly. The driving component is a first motor 206, which is fixedly mounted on one side of the first protective cover 201 via a base. The output end of the first motor 206 is fixedly mounted on one end of the blade 202. A cutting groove is provided on the top of the frame 1 for the blade 202 to pass through. The material to be cut is placed on the top of the frame 1. By pulling the control lever 207, the first protective cover 201 and the blade 202 are driven to rotate downward around the rotating rod 203. The connecting frame 204 and the counterweight 205 rotate simultaneously. The first motor 206 drives the blade 202 to rotate for cutting. The first protective cover 201 blocks some of the sparks to prevent them from splashing onto the operator in front.

[0023] The protective mechanism is located behind the blade 202 and includes a protective component and a collecting component. The protective component includes a second protective cover 301, a connecting frame 302, and a scraper 304. The second protective cover 301 is located behind the blade 202 and is quarter-circular. The connecting frame 302 is fixedly connected to the bottom of the second protective cover 301. The scraper 304 reciprocates within the second protective cover 301 via a first drive unit. The first drive unit includes a rotating shaft 303 and a second motor 305. The rotating shaft 303 is rotatably connected within the second protective cover 301, and the output end of the second motor 305 is fixed. The scraper 304 is fixedly installed at one end of the rotating shaft 303, and its bottom end is fixed on the outer wall of the rotating shaft 303. Sparks and molten slag particles splash backward from the cutting point along the cutting direction and enter the second protective cover 301, then fall into the collection frame 401 in the connecting frame 302. The rotating shaft 303 is driven to rotate 90° forward and then 90° backward by the second motor 305, which in turn drives the scraper 304 to rotate back and forth in the second protective cover 301. Thus, the scraper 304 scrapes off the molten slag particles adhering to the inner wall of the second protective cover 301, reducing the burden on the second protective cover 301 while improving the molten slag particle recovery effect.

[0024] The collection assembly includes a collection frame 401 and a pusher plate 403. The collection frame 401 is inserted into the bottom of the connecting frame 302. The pusher plate 403 slides back and forth within the collection frame 401 via a second drive unit. The second drive unit includes a lead screw 402 and a third motor 404. The lead screw 402 is rotatably connected within the connecting frame 302. The output end of the third motor 404 is fixedly installed at one end of the lead screw 402. The lead screw 402 is threadedly connected to the top of the pusher plate 403. A handle 405 is fixed to the bottom of the collection frame 401. The third motor 404 drives the lead screw 402 to rotate forward and then reverse 403, thereby driving the pusher plate 403 to move back and forth along both sides within the collection frame 401. This pushes the molten slag particles within the collection frame 401 to both sides and compresses them into blocks, reducing volume and facilitating transportation and subsequent processing. After a certain period of time, the collection frame 401 can be pulled down by pulling the handle 405 to pour out the molten slag particles within the collection frame 401.

[0025] Working principle: The material to be cut is placed on top of the frame 1. Pulling the control lever 207 causes the first protective cover 201 and the blade 202 to rotate downwards around the rotating rod 203. The connecting frame 204 and the counterweight 205 rotate simultaneously. The first motor 206 drives the blade 202 to rotate for cutting. The first protective cover 201 shields some of the sparks to prevent them from splashing onto the operator in front. Sparks and molten slag particles splash backwards from the cutting point along the cutting direction and enter the second protective cover 301 before falling into the collection box 401 inside the connecting frame 302. During this process, the second motor 305 drives the rotating shaft 303 to rotate 90° forward and then 90° backward. This causes the scraper 304 to rotate reciprocally within the second protective cover 301, thereby scraping off the slag particles adhering to the inner wall of the second protective cover 301. This reduces the burden on the second protective cover 301 while improving the slag particle recovery effect. The third motor 404 drives the lead screw 402 to rotate forward and then reverse 403, thereby driving the push plate 403 to move reciprocally along both sides within the collection frame 401. This push plate 403 pushes the slag particles in the collection frame 401 to both sides and compresses them into blocks, reducing the volume and facilitating transportation and subsequent processing. After a certain period of time, the collection frame 401 can be pulled down by pulling the handle 405 to pour out the slag particles in the collection frame 401.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
