[0031] See also Figure 1-5 The utility model provides a technical solution: an automatic feeding structure of a rubber cutting machine, comprising:

[0032] A cutting frame 100, and a cutting knife 200 disposed on the inner wall of the cutting frame 100;

Example

[0040] On the basis of the first embodiment, and different from the first embodiment,

[0041] An automatic feeding structure of a rubber cutting machine also includes:

[0042] The adjusting component 500 is used to control the feeding length. The adjusting component 500 includes a slider 501 slidably arranged on the back of the cutting frame 100, and a connecting plate 502 fixedly arranged on the side of the slider 501 and corresponding to the end of the sliding plate 303. A contact switch 503 is fixedly arranged on the upper surface of the connecting plate 502, and the contact switch 503 is electrically connected to the driving motor 302 through a wire. A triangular indicator block 504 is fixedly arranged on the other side surface of the slider 501, and a scale marking line 505 corresponding to the triangular indicator block 504 is arranged on the back of the cutting frame 100.

[0043] A strip groove is formed on the back of the cutting frame 100 , and a lead screw 506 is rotatably provided on the inner wall of the strip groove. The top end of the lead screw 506 extends to the upper surface of the cutting frame 100 and is fixed with a rotating block 507 .

[0044] The slider 501 is slidably connected to the inner wall of the strip groove, and a threaded hole is provided on the surface of the slider 501 to be threadedly connected to the outer surface of the lead screw 506 .

[0045] In this embodiment, by providing the adjustment component 500 , the purpose of cutting rubber strips of different widths can be achieved.

[0046] During operation, when the rubber is cut, the rubber sheet can be placed on the feed plate 401, and the driving motor 302 is started first to drive the threaded column 301 to rotate. The rotation of the threaded column 301 drives the sliding plate 303 and the cutting knife 200 to move upward. At the same time, the rotation of the threaded column 301 can drive the first bevel gear 407 to rotate. The rotation of the first bevel gear 407 drives the second bevel gear 408 and the connecting rod 405 to rotate. The rotation of the connecting rod 405 drives a plurality of worms 406 to rotate. The rotation of the worm 406 drives the worm wheel 404 to rotate, thereby driving a plurality of rotating shafts 402 and the conveying roller 403 to rotate at the same time, and the rubber sheet is conveyed into the interior of the cutting frame 100. Then, the driving motor 302 is started to reverse, driving the threaded column 301 to reverse, thereby driving the sliding plate 303 and the cutting knife 200 to move downward to automatically cut the rubber sheet. In addition, during the reversal of the threaded column 301, the first bevel gear 407 can be driven to reverse. The reversal of the first bevel gear 407 drives the second bevel gear 40 8 is reversed. When the second bevel gear 408 is reversed, it can drive the rotating plate 4011 to rotate through the stopper 4010, so that the second bevel gear 408 will not drive the connecting rod 405 to rotate during the reverse rotation, thereby ensuring the stability of the rubber plate when the cutting knife 200 cuts downward. The above steps can be repeated to achieve the purpose of unifying the width of the cut rubber strip, thereby effectively solving the defect that the fixed-length rubber cannot be continuously cut in the prior art. In addition, according to the actual width of the rubber strip to be cut, the rotating block 507 can be rotated to drive the lead screw 506 to rotate. The rotation of the lead screw 506 drives the slider 501 to move upward or downward, and the position of the triangular indicator block 504 on the scale mark line 505 is observed to determine the width of the rubber strip after cutting, so that the connecting plate 502 and the contact switch 503 can be fixed at the specified position. When the sliding plate 303 contacts the contact switch 503, the contact switch 503 can automatically control the driving motor 302 to reverse, thereby achieving the purpose of cutting rubber strips of different widths.

[0047] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
