[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1-5The present invention relates to a schematic diagram of a leather cutting device for processing briefcases. The device comprises a rocker arm cutting machine body 1, with a cutting plate 2 placed on the front top of the rocker arm cutting machine body 1 and fixed by two clamping plate assemblies 3. The feeding platform of the rocker arm cutting machine body 1 has longitudinal sliding openings 11 on both sides. A cutting and cleaning device 4 is fitted between the two longitudinal sliding openings 11 to scrape and clean leather debris from the feeding platform and cutting plate 2 of the rocker arm cutting machine body 1. The cutting and cleaning device 4 includes two slide rails 41, with a slider 42 movably mounted on each slide rail 41. A crossbeam 43 is positioned between the two sliders 42. A cleaning mechanism 44 is vertically arranged on the right side of the crossbeam 43. A vacuum cleaner 45 connected to the cleaning mechanism 44 is located at the left end of the crossbeam. A spacing sensor 46 is located on the bottom right side of the cleaning mechanism 44.

[0020] Two straw openings 431 are spaced apart on the right side of the crossbar 43.

[0021] The cleaning mechanism 44 includes a telescopic member 441, and a lifting plate 442 is provided on the bottom surface of the telescopic member 441. A scraping mechanism 443 is longitudinally provided in the middle of the lifting plate 442. Two suction nozzles 444 are provided on the left and right sides of the scraping mechanism 443. The upper ends of the two suction nozzles 444 are connected to suction hoses 445 that pass through the suction pipe opening 431 and communicate with the vacuum cleaner 45. Two support slide rods 446 that pass through the cross frame 43 are provided on the front and rear sides of the top of the lifting plate 442.

[0022] The scraping mechanism 443 includes a roller 4431, and a swing groove 4432 is provided in the middle of the top surface of the roller 4431. Two supports 4433 are hinged to the swing groove 4432 corresponding to the center point of the roller 4431. A motor 4434 for driving the roller 4431 to rotate at a 30º angle to the left and right of the center is connected to one of the supports 4433 at the left end. A brush 4435 is provided at the lower end of the cylinder of the roller 4431.

[0023] Working principle:

[0024] After cutting a piece of leather, a large amount of debris will be generated on the feeding table and cutting plate 2 of the main body 1 of the swing arm cutting machine. This debris needs to be scraped and cleaned by the cleaning mechanism 44. During operation, the vacuum cleaner 45 is turned on, and suction is generated by the two suction nozzles 444 through the suction hose 445. Then, the telescopic device 441 on the cleaning mechanism 44 drives the roller 4431 to rise, causing the brush 4435 to softly contact the feeding table. A specific distance sensing assists this process, while the motor 4434 drives the roller 4431 to rotate 30º to the left and right of its center, causing the brush 4435 to swing left and right to scrape. The debris is lifted and sucked away by the two suction nozzles 444, while the slider 42 slides forward on the slide rail 41. The auxiliary cleaning mechanism 44 moves forward. When the spacing sensor 46 moves forward and senses the cutting plate 2, the distance between the spacing sensor 46 and the cutting plate 2 will shorten. The roller 4431 needs to be lifted by the telescopic device 441 so that the brush 4435 can rise to softly contact the cutting plate 2 and swing to scrape the debris on the cutting plate 2. This prevents the brush 4435 from moving forward from the feeding table to the top surface of the cutting plate 2, where the roller 4431 will collide with the cutting plate 2 and get stuck due to the height difference between the two.
