The feeding wheel 3 is rotatably erected above the feeding table 2, the radius of the feeding wheel 3 is slightly smaller than the distance between the circle center of the feeding wheel 3 and the upper end face of the feeding table 2, so that the side face of the feeding wheel 3 is abutted to the cloth positioned on the feeding table 2, namely, the feeding wheel 3 rotates to drive the cloth to move along the length direction of the feeding table 2, and the cloth is conveyed to the cutting mechanism.

Wherein, the wheel surface sleeve of the feeding wheel 3 is provided with a wheel sleeve made of silica gel (which can be supported by other materials as long as the friction force between the feeding wheel 3 and the cloth can be improved). When the feeding wheel 3 feeds materials, the wheel sleeve can increase the friction force between the cloth and the feeding wheel 3, so that the feeding continuity and stability are ensured; and when the feeding wheel 3 is fixed, the wheel sleeve can ensure the fixing effect of the feeding wheel 3 on the cloth.

It should be noted that, after the wheel surface of the feeding wheel 3 is sleeved with the wheel sleeve, the radius of the feeding wheel 3 is still slightly smaller than the distance between the circle center of the feeding wheel 3 and the upper end surface of the feeding table 2, so as to ensure smooth feeding. Preferably, the radius of the feeding wheel 3 after the wheel sleeve is arranged on the sleeve is equal to the distance between the circle center of the feeding wheel 3 and the upper end surface of the feeding table 2, and the wheel sleeve is supported by silica gel and has elasticity, so that the friction force between the cloth and the feeding wheel 3 and the fixing effect of the feeding wheel 3 on the cloth are improved as far as possible on the premise that the cloth can smoothly pass through.

The connecting rod driving device comprises a first rod body 6, a second rod body 7, a driving wheel 8 and a rotating motor driving the driving wheel 8 to rotate. The right end of the first rod body 6 is connected with the left end of the second rod body 7 to form a connecting rod, and an included angle formed between the first rod body 6 and the second rod body 7 is an obtuse angle. The connecting point of the first rod body 6 and the second rod body 7 is hinged to the other side of the feeding table 2 through a pin shaft, so that the first rod body 6 and the second rod body 7 can be turned over up and down around the hinged point. In the overturning process, when the first rod body 6 overturns downwards around the hinge point, the second rod body 7 overturns upwards around the hinge point; when the first rod 6 is turned upwards around the hinge point, the second rod 7 is then turned downwards around the hinge point.

The end face of the driving wheel 8 is provided with a sliding groove which is composed of a first arc-shaped sliding groove 11 and a second arc-shaped sliding groove 12 which are communicated with each other, wherein the diameter of the circumference where the second arc-shaped sliding groove 12 is located is larger than that of the circumference where the first arc-shaped sliding groove 11 is located. The right end of the second rod body 7 is provided with a sliding block extending into the sliding groove. When the driving wheel 8 rotates, the sliding block enters the second arc-shaped sliding groove 12 from the first arc-shaped sliding groove 11 and then enters the first arc-shaped sliding groove 11 from the second arc-shaped sliding groove 12. Because the diameters of the circumferences of the two arc-shaped sliding grooves are different and the left end of the second rod body 7 is fixed, when the sliding block enters the second arc-shaped sliding groove 12 from the first arc-shaped sliding groove 11, the right end of the second rod body 7 moves downwards under the limiting action of the second sliding groove, so that the first rod body 6 turns downwards around the hinge point of the connecting rod; when the sliding block enters the first arc-shaped sliding groove 11 from the second arc-shaped sliding groove 12, the second rod body 7 is turned upwards around the hinged point of the connecting rod.

Articulated on the first body of rod 6 have first transfer line 9 and second transfer line 10, the upper end of first transfer line 9 and second transfer line 10 is articulated with first cutter blade 4 and second cutter blade 5 respectively, and the pin joint of first transfer line 9 and first cutter blade 4 is located the left side of round pin axle, and the pin joint of second transfer line 10 and second cutter blade 5 is located the right side of round pin axle. When the first transmission rod 9 upwards overturns around the hinge point of the connecting rod, the first cutting blade 4 is downwards overturned around the pin shaft by the transmission of the first transmission rod 9 and the second transmission rod 10, and the second cutting blade 5 is upwards overturned around the pin shaft by the shearing part of the second cutting blade 5, so that the second cutting blade 5 is upwards overturned around the pin shaft, and at the moment, the shearing parts of the two cutting blades are mutually close to finish cutting. From this, through the linkage cooperation of drive wheel 8 and connecting rod, make the rotating electrical machines drive wheel 8 and can drive first blade 4 and the second blade 5 of tailorring and tailor the cloth.

In addition, driven wheels 13 are coaxially and fixedly arranged on the two feeding wheels 3, and a driving wheel 14 in transmission connection with the driven wheels 13 is arranged on the feeding table 2. The two driving wheels 14 are in transmission connection through a transmission belt. Wherein, the driving wheel 14 is provided with a toothed part 15 and a toothless part 16, and the toothed part 15 can be meshed with the latch on the driven wheel 13. When the tooth part 15 is meshed with the driven wheel 13, the driving wheel 14 drives the driven wheel 13 to rotate, and further drives the feeding wheel 3 to rotate for feeding; when the toothed part 15 is disengaged from the driven wheel 13, the feeding wheel 3 is kept fixed and the cloth does not move any more. A driving bevel gear 20 is fixedly mounted on a rotating shaft of the driving wheel 8, the driving bevel gear 20 is meshed with a driven bevel gear 21, the rotating shaft of the driven bevel gear 21 is perpendicular to the rotating shaft of the driving wheel 8, and the rotating shaft of the driven bevel gear 21 is in transmission connection with the driving wheel 14 through a transmission belt. Thus, the driving wheel 8 can drive any driving wheel 14 to synchronously rotate, and then drive the other driving wheel 14 to rotate, so that the two driven wheels 13 are driven to rotate in a clearance manner, and intermittent feeding is realized.

Preferably, the latch teeth on the driven wheel 13 at two sides of the latch tooth section engaged with the toothed section 15 of the driving wheel 14 are set to be locking latch teeth 17, the end of the locking latch teeth 17 is set to be arc-shaped, and the arc-shaped is matched with the shape of the non-toothed section 16 of the driving wheel 14. After the toothed part 15 of the driving wheel 14 is meshed with the latch on the driven wheel 13 for transmission, the locking latch 17 of the driven wheel 13 is matched with the toothless part 16 of the driving wheel 14, so that the arc surface at the end part of the locking latch 17 is attached to the end surface of the toothless part 16 of the driving wheel 14, and the driven wheel 13 is limited in rotation.

It should be noted that, when the toothless part 16 on the driving wheel 14 is meshed with the driven wheel 13, the feeding wheel 3 conveys the fabric, and at this time, the slider should be located in the first arc-shaped chute 11, so that the cutting parts of the first cutting blade 4 and the second cutting blade 5 are in a state of being away from each other, which is convenient for the fabric to pass through the cutting mechanism smoothly; during the period that the toothed part 15 on the driving wheel 14 is disengaged from the driven wheel 13, the feeding wheel 3 stops rotating, the cloth is fixed on the feeding table 2, during the period, the sliding block enters the second arc-shaped sliding groove 12 from the first arc-shaped sliding groove 11, so that the first cutting blade 4 and the second cutting blade 5 complete one cutting action, then the sliding block enters the first arc-shaped sliding groove 11 from the second arc-shaped sliding groove 12, the cutting parts of the first cutting blade 4 and the second cutting blade 5 are mutually separated until the initial state is recovered, and then the toothed part 15 of the driving wheel 14 is meshed with the driven wheel 13 again, so that the circular work is realized.

Therefore, the cutting blade and the feeding wheel 3 can be simultaneously driven to cut by the rotating motor in the cutting mechanism, so that one power source drives all the motion mechanisms in the cutting device, the linkage among the motion mechanisms is realized, the whole cutting process is continuous and cyclic, and the efficiency of cutting work is improved.
