[0022] The present invention has the following technical effects:

[0023] 1. When the raw material is sent to between the feed rollers through the automatic one-by-one feeding assembly, the second motor is started, and the second motor drives the first rotating rod to rotate. The first rotating rod drives the feed roller to rotate through the first driving bevel gear and the first driven bevel gear. The two groups of feed rollers drive the raw material to move in the direction close to the self-locking cutting and collecting assembly. When it is necessary to transmit raw materials of different thicknesses, the first motor is started, the first motor drives the bidirectional threaded rod to rotate, the bidirectional threaded rod drives the two groups of support sliders to approach or move away from each other, and the support slider drives the two groups of feed rollers to move away from or approach each other, thereby realizing the adjustment of the spacing between the feed rollers. When the feed roller moves, the first driving bevel gear is driven by the first L-shaped support plate to move up and down under the limit of the first rotating rod. Since the first driving bevel gear is connected to the first rotating rod in a limited sliding connection and the first driving bevel gear and the first driven bevel gear are always in meshing state, the rotation of the feed roller will not be affected when the spacing between the feed rollers is adjusted, so that the device can be suitable for raw materials of various thicknesses, and can also be adjusted at any time during the operation of the device without stopping, thereby improving production efficiency and ensuring product quality.

[0024] 2. When the raw material is sent by the feed roller to the right end of the contact cutting blade, it is cut into two parts by the cutting blade, and the lower part of the raw material falls into the space on the right side of the baffle below the cutting blade. At this time, the first rotating rod drives the second rotating rod to rotate through the transmission mechanism, and the second rotating rod drives the pulling roller to rotate through the second driving bevel gear and the second driven bevel gear, so that the pulling roller drives the upper part of the raw material to pass between the pulling roller and the driven pulling roller, so that the upper part of the raw material always has a pulling force to the left, avoiding the accumulation of raw materials due to insufficient conveying force, so that there is no need to manually pull out the upper part of the raw material. At this time, the raw material falls into the space on the left side of the baffle under the guidance of the cutting blade and the guide ramp, realizing the product Automatic classification and collection. When the cutting blade needs to be repaired, the first motor is started, and the first motor drives the two groups of supporting slide blocks to move away from each other, so that the upper group of supporting slide blocks drives the pulling roller and the positioning locking plate to move upward, so that the positioning locking plate disengages from the positioning locking groove, and then completes the unlocking of the cutting blade. At this time, the cutting blade can be pulled out to repair the cutting blade. It is simple and convenient. When the repair is completed, the cutting blade is pushed to the far right end. At this time, the pulling roller drives the positioning locking plate to move downward until it is clamped in the positioning locking groove. At this time, the positioning and fixing of the cutting blade are completed, which ensures the accurate positioning of the cutting blade and the stability of the cutting blade when the device is working.

[0025] When the upper group of support slides moves to the rightmost end and blocks the discharge port below the storage box, the upper group of limit slides enters the inclined part of the second limit slide, and the arched driving plate continues to move downward, so that the second limit slide drives the upper group of support slides to move to the right through the limit slide. The upper group of U-shaped driving frames and supporting slides move to the left, and because the rear group of limiting slides are located in the vertical part of the first limiting slide groove at this time, the lower group of supporting slides remain stationary. When the supporting slide moves to the leftmost end, the raw materials in the material storage box fall onto the lower group of supporting slides. At this time, the third motor is started, and the third motor drives the arched driving plate to move upward, so that the upper group moves to the right under the limit of the limiting slide. Since the right end of the upper group of supporting slides is knife-shaped, the upper group of supporting slides isolates a piece of raw material between the two groups of supporting slides. When the supporting slide moves to the rightmost end, the lower group of supporting slides moves to the left under the limit of the first limiting slide groove, so that the raw materials between the two groups of supporting slides fall onto the transmission belt and are transported by the transmission belt to between the two groups of feeding rollers, thereby realizing automatic loading of raw materials. Repeating the above operations can realize automatic loading of raw materials one by one. BRIEF DESCRIPTION OF THE DRAWINGS

A first limiting slide groove 524 is provided on the rear plate of the driving plate 522, a second limiting slide groove 525 is provided on the front plate of the arched driving plate 522, the right end of the front side wall of the upper group of U-shaped driving frames 515 and the right end of the rear side wall of the lower group of U-shaped driving frames 515 are both fixedly connected to a limiting slider 526, the front group of limiting sliders 526 pass through the second limiting slide groove 525 and are slidably connected to the second limiting slide groove 525, and the rear group of limiting sliders 526 pass through the first limiting slide groove 524 and are slidably connected to the first limiting slide groove 524;

[0059] The upper part of the first limiting slide groove 524 is a vertical slide groove, the lower part of the first limiting slide groove 524 is an inclined slide groove obliquely directed to the lower left, the upper part of the second limiting slide groove 525 is an inclined slide groove obliquely directed to the upper left, and the lower part of the second limiting slide groove 525 is a vertical slide groove;

[0060] The right end of the arched driving plate 522 is slidably connected to the support frame 511 through a limit sliding rod, and the right end of the upper set of supporting slide plates 514 is knife-edge shaped;

[0061] When the raw materials need to be processed, the raw materials are neatly placed in the material storage box 513, and the third motor 521 is started at this time. The third motor 521 drives the arched driving plate 522 to move downward through the threaded rod 523. At this time, the arched driving plate 522 drives the second limiting slide 525 and the first limiting slide 524 to move downward, so that under the limitation of the first limiting slide 524 and the second limiting slide 525, the first limiting slide 524 drives the lower group of U-shaped driving frames 515 to move to the right through the limiting slider 526 under the limitation of the limiting guide rod 516. As a result, the lower group of U-shaped driving frames 515 drive the lower group of supporting slides 514 to move to the right. At this time, since the front group of limiting slide blocks 526 are located in the vertical part of the second limiting slide groove 525, the upper group of supporting slide blocks 514 do not move. When the upper group of supporting slide blocks 514 move to the rightmost end and block the discharge port below the storage box 513, the front group of limiting slide blocks 526 enter the inclined part of the second limiting slide groove 525. At this time, the arched driving plate 522 continues to move downward, so that the second limiting slide groove 525 passes through the limiting slide block 5 26 drives the upper group of U-shaped driving frame 515 and supporting slide plate 514 to move to the left, and because the rear group of limiting slide blocks 526 is located at the vertical part of the first limiting slide groove 524 at this time, the lower group of supporting slide plates 514 remain motionless. When the supporting slide plate 514 moves to the leftmost end, the raw materials in the storage box 513 fall onto the lower group of supporting slide plates 514. At this time, the third motor 521 is started, and the third motor 521 drives the arched driving plate 522 to move upward, so that the upper group moves to the right under the limit of the limiting slide block 526. The right end of the upper group of support slides 514 is in a knife-edge shape, so that the upper group of support slides 514 isolates a piece of raw material between the two groups of support slides 514. When the support slide 514 moves to the rightmost end, the lower group of support slides 514 moves to the left under the limit of the first limiting slide groove 524, so that the raw material between the two groups of support slides 514 falls onto the transmission belt 512 and is transported by the transmission belt 512 to between the two groups of feeding rollers 314, thereby realizing automatic loading of the raw materials. Repeating the above operation can realize automatic loading of the raw materials one by one.
