Referring to fig. 1-4, a high stability leather cutting machine for shoemaking comprises a frame 1, a cam 2 movably connected to the top of the frame 1, a lower pressing block 3 movably connected to the lower portion of the cam 2, two ends of the lower pressing block 4 movably connected to the inside of the frame 1, return springs 5 respectively disposed at the upper and lower portions, return springs 5 movably connected to the two sides of the lower pressing block 4, a connector 7 movably connected to the lower portion of the lower pressing block 4, a knife mold plate 8 movably connected to the outer side of the lower end of the connector 7, the connector 7 having two parts, the upper portion having a trapezoidal structure with a wide upper portion and a narrow lower portion, the knife mold plate 8 having a trapezoidal hole adapted thereto, the trapezoidal structure passing through the knife mold plate 8, the lower end of the connector 7 movably connected to the inside of the knife mold plate 8, a fixing block 9 movably connected to the inner sidewall of the knife mold plate 8, a self-locking lever 10 movably connected to the inside, the self-locking rod 10 is provided with a groove, when the self-locking rod 10 falls down, the groove can drive the pawl 11 to bounce, the outer side of the lower end of the connector 7 is provided with a ratchet strip, the ratchet strip is matched with the pawl 11, the upper part of the fixed block 9 is movably connected with a movable rod 12, the lower part of the movable rod 12 is provided with a rack, the rack is meshed with a first unlocking gear 13, the left side of the first unlocking gear 13 is meshed with a second unlocking gear 14, the lower surface of the second unlocking gear 14 is meshed with a pin 15, the pin 15 is provided with the rack, the lower part of the knife template 8 is movably connected with a lower template 6, the bottom of the knife template 8 is provided with a cutting knife, the lower template 6 is provided with a trapezoidal through hole, the cutting knife is coaxial with a trapezoidal hole on the lower template 6, the lower part of the lower template 6 is movably connected with a discharge template 16, the inside of the gear ring 17 is engaged with a rotating gear 18, the front surface of the rotating gear 18 is movably connected with a slide rod 19, one end of the slide rod 19 is movably connected on the rotating gear 18, the other end of the slide rod is movably connected with a slide block, and the slide block is movably connected in a groove of the discharging plate 16.

The working process and principle are as follows: because of manufacturing and installation reasons, after the cutting machine is fixed, a certain gap is formed between the connector 7 and the cutter template 8, in order to eliminate the influence caused by the gap, the first cutting process of the cutting machine is idle stroke and is used for adjusting the machine, the machine is started, the motor drives the cam 2 to start rotating, the convex part of the cam 2 presses the lower pressing block 3 and the lower pressing plate 4 downwards, the return spring 5 is compressed, meanwhile, the trapezoidal structure part of the connector 7 is downward and gradually attached to the trapezoidal hole on the cutter template 8, because of the structure that the upper part is wide and the lower part is narrow, the trapezoidal part of the connector 7 is matched with the cutter template 8 more and more tightly, when the connector 7 is downward, the ratchet strip on the side of the lower part of the connector 7 moves downward, when the lowest point is reached, the pawl 11 locks the ratchet strip, when the cutting of the machine is finished once, and when the return stroke is finished, because the trapezoidal structure on the upper end, the auto-lock of cooperation lower extreme pawl 11 and ratchet strip can be fixed between connector 7 and the cutting die board 8, and cutting die board 8 does not take place the displacement for connector 7, and the precision that the leather surface fabric cut obtains improving, and the leather can not produce deckle edge, and appearance quality obtains improving.

After the machine is adjusted, leather to be cut is conveyed to the lower template 6 through the feeding device, the machine is started, the process is the same as that described above, the connector 7 pushes the cutter template 8 to press downwards, the cutter at the lower end of the cutter template 8 is known to cut the leather, because the lower template 6 is provided with a trapezoidal through hole and the cutter is coaxial with a trapezoidal hole on the lower template 6, after the leather is cut, the lower pressing block 3, the lower pressing plate 4, the connector 7 and the cutter template 8 are lifted under the restoring force of the restoring spring 5, the cut leather falls onto the discharge plate 16 through the hole on the lower template 6, at the moment, the motor drives the connecting rod to rotate around the center of the gear ring 17, the rotating gear 18 at the tail end of the connecting rod rotates in the gear ring 17, the sliding rod 19 movably connected to the rotating gear 18 can push the sliding block connected at the right end of the sliding rod 19 to reciprocate, when the sliding block moves to the right, the operator only needs to collect the products on the discharge plate 16, and does not need to collect the products from the inside of the machine, so that the working efficiency is improved, and the safety is also ensured.

When the cutting die plate 8 needs to be maintained and replaced, the movable rod 12 is pulled upwards, the first unlocking gear 13 and the second unlocking gear 14 are driven to rotate through the rack on the movable rod 12, the pin 15 can be pulled to move rightwards, the self-locking rod 10 falls down under the action of gravity at the moment, the groove on the self-locking rod 10 can drive the pawl 11 to bounce, the pawl 11 loses the self-locking function at the moment, the connector 7 and the cutting die plate 8 are not fixed any more, and the machine is convenient to maintain and replace.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
