Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting of shoe upper materials, and in particular to an intelligent cutting machine for shoe upper materials and a cutting method thereof. Background Art

[0002] The upper material includes the inner wrapping part. The common characteristics of the upper should be soft to the touch, heat preservation, air absorption, moisture dissipation, lightness and bending resistance, wear resistance, water and heat resistance, easy processing and non-fading. During the shoe production process, the upper material needs to be cut into multiple standard sheet objects so that the upper can be fitted to the sole.

[0003] Currently, shoe upper materials are usually cut using a laser cutter. However, if the shoe upper material itself has wrinkles during cutting, the cut standard sheet object may have size deviations, and the existing wrinkles need to be manually ironed, which is very troublesome. In addition, during laser cutting, the thickness of the shoe upper material varies. If the height of the laser emitting device remains unchanged, the thinner shoe upper material will be more easily damaged by the high laser temperature, while the thicker shoe upper material may not be cut completely due to the low laser temperature.

[0004] Based on this, we propose an intelligent cutting machine for upper materials and a cutting method thereof. Summary of the Invention

[0018] A method for intelligently cutting a shoe upper material comprises the following steps:

[0019] S1. Pass the upper material through the screed plate and the lower end of the laser cutting machine in sequence, and fix one end of it to the side wall of the winding roller. Then drive the reversible motor to rotate in the forward direction, which can drive the winding roller to rotate, and then pull the upper material to move a certain distance;

[0020] S2. When the upper material is pulled, the screed plate will reciprocate and rotate to press and remove wrinkles on the surface of the upper material, making the surface of the upper material flat;

[0021] S3, then start the laser cutting machine and synchronously drive the reversible motor to rotate in the opposite direction. The laser cutting machine will cut the shoe upper material into the shoe upper shape at a certain position according to the set program, and the laser cutting machine will intermittently move a certain distance to cut different positions of the shoe upper material.

[0022] S4. During the cutting process, the fan blades will rotate rapidly, thereby generating suction force to absorb the smoke generated during the laser cutting process through the smoke removal head, and then the smoke will be discharged to the external smoke collection device through the smoke exhaust pipe;

[0023] S5. Finally, the cut upper materials can be taken out, collected, and stored in a warehouse.

[0024] The present invention has the following beneficial effects:

[0025] 1. By setting up a wrinkle removal mechanism, the reciprocating movement of the screed plate can rub and flatten the upper material, thereby eliminating wrinkles and preventing the size of the sheet objects cut later from being unqualified. The screed plate can also rotate on its own to provide tangential force, thereby improving the flattening effect of the upper material and enhancing the wrinkle removal effect.

[0026] 2. By setting up a static elimination mechanism, the rotation of the shaft will synchronously drive the cam to rotate. Under the action of the cam and the second spring, the T-bar will drive the sliding plug to slide back and forth in a sealed manner, and then the external hot water will be drawn into the pump water cylinder through the one-way water inlet pipe, and then the hot water will enter the atomizing nozzle through the one-way water outlet pipe. Finally, the hot water will be sprayed out through the atomizing nozzle and sprayed onto the surface of the shoe upper material after the wrinkles are removed, wetting the shoe upper material. Due to the intense friction between the leveling plate and the inclined material during leveling, the inclined material will be charged with static electricity, which can be eliminated by spraying hot water;

[0027] 3. By setting up components such as vertical cylinders and connecting pipes, for shoe upper materials of different thicknesses, if the shoe upper material is thicker, the height of the screed plate will be higher, and thus the height of the connecting shaft in the vertical groove will be higher, more air will enter the vertical cylinder through the connecting pipe, making the position of the slide plate lower, and thus the height of the laser cutter lower, so that the laser beam emitted by the laser cutter is more concentrated when it contacts the shoe upper material, providing a higher temperature for cutting, avoiding incomplete cutting. On the contrary, if the thickness of the shoe upper material is thinner, the height of the laser cutter is higher, the emitted laser beam will be more dispersed when it contacts the shoe upper material, and thus the temperature will be lower, avoiding excessive temperature from damaging the thinner shoe upper material;

[0028] 4. By setting up a smoke removal mechanism, when the second rotating rod rotates, it will synchronously drive multiple fan blades to rotate, thereby generating suction force, and then the smoke generated during the laser cutting process will be sucked into the smoke removal cylinder through the smoke removal head and the smoke removal pipe, and then the smoke will be discharged to the external smoke collection device through the smoke exhaust pipe, thereby preventing the smoke generated during laser cutting from flying into the working environment and polluting the working environment.

The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention.

[0042] Two L-shaped frames 21 are symmetrically fixedly connected to the side walls of the cutting table 1 . The side walls of the two L-shaped frames 21 close to each other are rotatably connected to a first rotating rod 22 . A winding roller 23 is fixedly connected to the side wall of the first rotating rod 22 .

[0043] A first driving mechanism is installed on the cutting table 1, and the first driving mechanism includes a reversible motor 24 fixedly connected to the side wall of the cutting table 1 through a bracket, the output end of the reversible motor 24 is fixedly connected to the first one-way bearing 25, and the other end of the first one-way bearing 25 is fixedly connected to the second one-way bearing 26, one end of the first rotating rod 22 passes through the side wall of the L-shaped frame 21 and is fixedly connected to the second one-way bearing 26, the inner wall of the first slide groove 4 is rotatably connected to the first reciprocating screw 27, the side wall of the first reciprocating screw 27 is threadedly connected to the first slider 5, the side wall of the first rotating rod 22 is fixedly connected to the first driving wheel 28, one end of the first reciprocating screw 27 passes through the side wall of the first mounting frame 3 and is fixedly connected to the first driven wheel 29, and the first driving wheel 28 is connected to the first driven wheel 29 through a synchronous belt.

[0044] Furthermore, the reversible motor 24 is driven to rotate in the forward direction, driving the first rotating rod 22 to rotate, and then driving the winding roller 23 to rotate, and winding the upper material, thereby pulling the upper material to the right for a distance, so that the cutting part moves to the bottom of the laser cutting machine 2, and when the first rotating rod 22 rotates, it will synchronously drive the first driving wheel 28 to rotate, and then drive the first driven wheel 29 to rotate, and drive the first reciprocating screw 27 to rotate, thereby driving the first slider 5 to slide back and forth on the inner wall of the first slide groove 4, and driving the smoothing plate 9 to slide back and forth, frictionally smoothing the upper material, thereby eliminating wrinkles and avoiding unqualified size of sheet objects cut out later.

[0045] It is worth mentioning that when the first slider 5 slides back and forth, it will drive the first gear 13 to move. Since the first gear 13 is engaged with the rack 12, the first gear 13 will rotate synchronously, thereby driving the rotating shaft 6 to rotate, driving the connecting shaft 8 to rotate, and thus driving the smoothing plate 9 to rotate. The rotation of the smoothing plate 9 can provide a tangential force, thereby improving the leveling effect of the upper material and enhancing the wrinkle removal effect.

Finally, the hot water will be atomized and sprayed out through the atomizing nozzle 11, sprayed onto the surface of the shoe upper material after the wrinkles are removed, and the shoe upper material is moistened. Since the leveling plate 9 generates severe friction with the inclined material when leveling, the inclined material will have static electricity, which can be eliminated by spraying hot water.

[0047] A laser cutting mechanism is installed on the cutting table 1, and the laser cutting mechanism includes a second mounting bracket 30 fixedly connected to the upper end of the cutting table 1. A second slide groove 31 is provided on the side wall of the second mounting bracket 30. A second slider 32 is slidably connected to the inner wall of the second slide groove 31. The lower end of the second slider 32 is slidably connected to a mounting rod 33. The laser cutting machine 2 is fixedly connected to the lower end of the mounting rod 33.

[0048] The upper end of the second slider 32 is fixedly connected to the vertical cylinder 34, and the inner wall of the vertical cylinder 34 is sealed and slidably connected to the slide 35.

The side wall of the first slider 5 is fixedly connected to the rotating joint 49 through the bracket, and the upper end of the rotating shaft 6 is fixedly connected to the rotating joint 49. The upper end of the rotating joint 49 is fixedly connected to the connecting pipe 36. The other end of the connecting pipe 36 is connected to the vertical cylinder 34. The connecting pipe 36 is connected to the upper space of the slide 35, and the connecting pipe 36 is made of a hose.

[0049] Furthermore, for shoe upper materials of different thicknesses, if the shoe upper material is thicker, the height of the leveling plate 9 will be higher, and the height of the connecting shaft 8 in the vertical groove 7 will be higher, more air will enter the vertical cylinder 34 through the connecting pipe 36, making the position of the slide plate 35 lower, and the height of the laser cutter 2 lower, so that the laser beam emitted by the laser cutter 2 is more concentrated when it contacts the shoe upper material, providing a higher temperature for cutting, avoiding incomplete cutting. On the contrary, if the thickness of the shoe upper material is thinner, the height of the laser cutter 2 is higher, the emitted laser beam will be more dispersed when it contacts the shoe upper material, and the temperature will be lower, avoiding excessive temperature to damage the thinner shoe upper material.

[0050] A smoke removal mechanism is installed on the laser cutting machine 2, which includes a smoke removal head 37 fixedly connected to the side wall of the laser cutting machine 2 through a fixed shaft, a smoke removal cylinder 38 fixedly connected to the top of the second mounting frame 30 through a bracket, a second rotating rod 39 is rotatably connected to the inner wall of the smoke removal cylinder 38, and a plurality of fan blades 40 are fixedly connected to the side wall of the second rotating rod 39, the smoke removal cylinder 38 is connected to the smoke removal head 37 through a smoke removal pipe 41, and two smoke exhaust pipes 42 are symmetrically fixedly connected to the side wall of the smoke removal cylinder 38, and the smoke exhaust pipe 42 is connected to an external smoke collection device.

[0051] A second driving mechanism is installed in the second slide groove 31, and the second driving mechanism includes a second reciprocating screw 43 rotatably connected to the inner wall of the second slide groove 31, the side wall of the second reciprocating screw 43 is threadedly connected to the second slider 32, one end of the second reciprocating screw 43 passes through the side wall of the second mounting frame 30 and is fixedly connected to the second gear 44, one end of the second rotating rod 39 passes through the side wall of the second mounting frame 30 and is fixedly connected to the sector gear 45, the side wall of the first one-way bearing 25 is fixedly connected to the second driving wheel 46, the side wall of the second rotating rod 39 is fixedly connected to the second driven wheel 47, and the second driving wheel 46 is connected to the second driven wheel 47 through a synchronous belt.

[0052] It should be noted that the first one-way bearing 25 and the second one-way bearing 26 are arranged in opposite directions, the output end of the reversible motor 24 is fixedly connected to the inner ring of the first one-way bearing 25, the outer ring of the second one-way bearing 26 is fixedly connected to the inner ring of the first one-way bearing 25, the first rotating rod 22 is fixedly connected to the inner ring of the second one-way bearing 26, and the second driving wheel 46 is fixedly connected to the outer ring of the first one-way bearing 25. When the reversible motor 24 rotates forward, it will drive the first rotating rod 22 to rotate. At this time, the second driving wheel 46 will not rotate. When the reversible motor 24 rotates backward, it will drive the second driving wheel 46 to rotate. At this time, the first rotating rod 22 will not rotate.

[0053] Furthermore, when the second rotating rod 39 rotates, it will synchronously drive the multiple fan blades 40 to rotate, thereby generating a suction force, and the smoke generated during the laser cutting process will be sucked into the smoke removal tube 38 through the smoke removal head 37 and the smoke removal tube 41, and then the smoke will be discharged to the external smoke collection device through the smoke exhaust pipe 42, thereby preventing the smoke generated during laser cutting from flying into the working environment and polluting the working environment.

[0054] A method for intelligently cutting a shoe upper material comprises the following steps:

[0055] S1. Pass the upper material through the screed plate 9 and the lower end of the laser cutter 2 in sequence, and fix one end of the material to the side wall of the winding roller 23. Then drive the reversible motor 24 to rotate in the forward direction, which can drive the winding roller 23 to rotate, thereby pulling the upper material to move a certain distance.

[0056] S2. When the upper material is pulled, the screed plate 9 will reciprocate and rotate to press and remove wrinkles on the surface of the upper material, thereby flattening the surface of the upper material;

[0057] S3, then start the laser cutter 2 and synchronously drive the reversible motor 24 to rotate in the opposite direction. The laser cutter 2 will cut the shoe upper material into the shape of the shoe upper at a certain position according to the set program, and the laser cutter 2 will intermittently move a certain distance to cut different positions of the shoe upper material;

[0058] S4. During the cutting process, the fan blades 40 rotate rapidly, thereby generating a suction force to remove the smoke generated during the laser cutting process through the smoke removal head 37, and then the smoke is discharged to the external smoke collection device through the smoke exhaust pipe 42;

[0059] S5. Finally, the cut upper materials can be taken out, collected, and stored in a warehouse.

[0060] In the present invention, one end of the upper material is first pulled so that the upper material passes through the screed plate 9 and the lower end of the laser cutter 2 in turn, and one end is fixed to the side wall of the winding roller 23. Then, the reversible motor 24 is driven to rotate in the forward direction, driving the first rotating rod 22 to rotate, and then driving the winding roller 23 to rotate to rewind the upper material, thereby pulling the upper material to the right for a distance, so that the cutting part moves to the bottom of the laser cutter 2.

[0061] When the first rotating rod 22 rotates, it will synchronously drive the first driving wheel 28 to rotate, and then drive the first driven wheel 29 to rotate, drive the first reciprocating screw 27 to rotate, thereby driving the first slider 5 to slide back and forth on the inner wall of the first slide groove 4, and drive the leveling plate 9 to slide back and forth, frictionally leveling the upper material, thereby eliminating wrinkles and preventing the sheet objects cut later from being of unqualified size.

[0062] In addition, when the first slider 5 slides back and forth, it will drive the first gear 13 to move. Since the first gear 13 is engaged with the rack 12, the first gear 13 will rotate synchronously, thereby driving the rotating shaft 6 to rotate, driving the connecting shaft 8 to rotate, and thus driving the smoothing plate 9 to rotate. The rotation of the smoothing plate 9 can provide a tangential force, thereby improving the leveling effect of the upper material and enhancing the wrinkle removal effect.

[0063] When the rotating shaft 6 rotates, it will synchronously drive the cam 20 to rotate. Under the action of the cam 20 and the second spring 19, the T-bar 18 will drive the sliding plug 15 to slide back and forth in a sealed manner, and then the external hot water will be drawn into the pump water cylinder 14 through the one-way water inlet pipe 16, and then the hot water will enter the atomizing nozzle 11 through the one-way water outlet pipe 17. Finally, the hot water will be atomized and sprayed out through the atomizing nozzle 11, spraying onto the surface of the shoe upper material after the wrinkles are removed, wetting the shoe upper material. Since the leveling plate 9 generates severe friction with the inclined material when leveling, the inclined material will have static electricity, which can be eliminated by spraying hot water.

[0064] Then, the reversible motor 24 is driven to rotate in the opposite direction and the laser cutting machine 2 is started synchronously. The laser cutting machine 2 will run under the program set externally to cut the shoe upper material into a specific shape, and the reversible motor 24 will drive the second driving wheel 46 to rotate, thereby driving the second driven wheel 47 to rotate, driving the second rotating rod 39 to rotate, and the second rotating rod 39 will drive the sector gear 45 to rotate. When the sector gear 45 rotates to engage with the second gear 44, it will drive the second reciprocating screw 43 to rotate, thereby driving the second slider 32 to slide on the inner wall of the second slide groove 31, thereby driving the laser cutting machine 2 to move forward or backward for a distance to cut other parts of the shoe upper material. Since the sector gear 45 and the second gear 44 are intermittently engaged, the second reciprocating screw 43 rotates intermittently, so that the laser cutting machine 2 moves intermittently, providing sufficient time for cutting.

[0065] When the second rotating rod 39 rotates, it will synchronously drive the multiple fan blades 40 to rotate, thereby generating a suction force, and the smoke generated during the laser cutting process will be sucked into the smoke removal tube 38 through the smoke removal head 37 and the smoke removal tube 41, and then the smoke will be discharged to the external smoke collection device through the smoke exhaust pipe 42, thereby preventing the smoke generated during laser cutting from flying into the working environment and polluting the working environment.

[0066] For shoe upper materials of different thicknesses, if the shoe upper material is thicker, the height of the leveling plate 9 will be higher, and the height of the connecting shaft 8 in the vertical groove 7 will be higher, more air will enter the vertical cylinder 34 through the connecting pipe 36, making the position of the slide plate 35 lower, and the height of the laser cutter 2 will be lower, so that the laser beam emitted by the laser cutter 2 is more concentrated when it contacts the shoe upper material, providing a higher temperature for cutting, avoiding incomplete cutting. On the contrary, if the thickness of the shoe upper material is thinner, the height of the laser cutter 2 is higher, the emitted laser beam will be more dispersed when it contacts the shoe upper material, and the temperature will be lower, avoiding excessive temperature causing damage to the thinner shoe upper material.
