Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device for leather processing. Background Art

[0002] Leather is the animal skin that has been denatured and is not easily perishable through physical and chemical processes such as hair removal and tanning. Leather is composed of natural protein fibers woven in three-dimensional space, with a special grain layer on its surface, having natural grain patterns and luster, and a comfortable touch. The leather industry covers main industries such as leather making, shoe making, leather clothing, and leather goods. Generally, it undergoes laser cutting to remove excess leather. When laser cutting leather, since the organic components contained in the leather are heated and decomposed, gases and fine particles are released to form smoke. This smoke will have a certain impact on the physical health of the staff. During processing, a smoking mechanism is often equipped. However, the existing smoking mechanism is located on one side of the laser cutting head. When the leather has special situations such as incorrect cutting focus, a large amount of smoke will be generated. At this time, the smoking mechanism on one side of the cutting head cannot completely suck it out, which will have a certain impact on the staff and the environment. Moreover, most of the existing leather is directly placed on the cutting table. After cutting, for some small pieces of cut leather, the negative pressure generated by the smoking mechanism during air suction is likely to suck away the cut leather, resulting in waste of leather and easily causing blockage of the smoking mechanism.

[0003] Therefore, the present invention provides a laser cutting device for leather processing. Summary of the Invention

[0032] To make the technical means, creative features, achieved purposes, and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a laser cutting device for leather processing, including an outer shell 1, a sliding plate 6 is slidably fitted in the outer shell 1, a placing plate 12 is installed on the sliding plate 6, auxiliary structures are installed on both sides of the outer shell 1, the auxiliary structures correspond to the placing plate 12, a limiting structure is installed in the outer shell 1, the limiting structure corresponds to the placing plate 12, an air extraction structure is installed in the outer shell 1, the air extraction structure corresponds to the sliding plate 6, a feeding structure and a communicating structure are installed between the sliding plate 6 and the placing plate 12, a plurality of air inlet holes 14 are opened on the placing plate 12, a laser cutting structure is slidably fitted in the outer shell 1, the laser cutting structure includes a shielding cover 28, the shielding cover 28 corresponds to the placing plate 12, an air extraction head 31 is slidably fitted in the outer shell 1, the air extraction head 31 corresponds to the shielding cover 28, and an anti-wrinkle structure is installed on one side of the outer shell 1.

[0034] In this embodiment, the auxiliary structure includes an auxiliary plate 2 which is fixedly connected to the outer shell 1. The feeding structure includes a first electric slide rail 15 fixed on the sliding plate 6. The output end of the first electric slide rail 15 is fixed with a first slider 16. A clamping structure is installed between the first slider 16 and the placing plate 12. A first chute 20 is formed on the sliding plate 6, and a second chute 22 is formed on the auxiliary plate 2. A second slider 21 is fixed to the lower side of the placing plate 12, and the second slider 21 corresponds to the first chute 20 and the second chute 22.

[0035] Specifically, when the first electric slide rail 15 is started, the first slider 16 can be driven to slide by the first electric slide rail 15, thereby driving the placing plate 12 to slide, and the placing plate 12 can be slid out onto the auxiliary plate 2. At this time, the second slider 21 slides from the first chute 20 into the second chute 22, so as to realize sliding out the placing plate 12, and the leather placed on the placing plate 12 after cutting can be removed. At this time, the leather is far away from the laser cutting head 30, so there is no need to worry about the contact between the leather or the staff and the laser cutting head 30, thus preventing burns.

[0036] When feeding, the leather is placed on the placing plate 12 on another auxiliary plate 2. After the placing plate 12 in the outer shell 1 slides out, the placing plate 12 on the other auxiliary plate 2 is manually pushed, and the placing plate 12 can be pushed into the outer shell 1. Then, the placing plate 12 is pushed upward by the sliding plate 6, and the leather on the placing plate 12 can be processed. And when processing, at this time, another placing plate 12 can be placed on the auxiliary plate 2, the leather is laid flat on the placing plate 12, and the leather cut on the other side can also be removed, so as to prevent the contact between the leather or the staff and the laser cutting head 30, and load and unload materials while cutting, improving work efficiency.

[0037] The clamping structure includes a clamping block 17 fixed on the first slider 16. A clamping groove 18 is formed on the lower side of the placing plate 12, and the clamping groove 18 corresponds to the clamping block 17. The limiting structure includes a limiting plate 9 fixed in the outer shell 1. The limiting plate 9 is located under the placing plate 12. An electric cylinder 7 and a plurality of telescopic rods 8 are fixed in the outer shell 1. The output end of the electric cylinder 7 is fixedly connected to the sliding plate 6, and one end of the telescopic rod 8 is fixedly connected to the sliding plate 6.

[0038] Specifically, when the electric cylinder 7 is started, the sliding plate 6 can be driven by the electric cylinder 7 to move up and down, thereby driving the placement plate 12 to move up and down. When the placement plate 12 is sent out, the electric cylinder 7 is started at this time, so that the electric cylinder 7 drives the placement plate 12 to move to the discharge port 42. At this time, the limiting plate 9 is in contact with the placement plate 12. Then, the first electric slide rail 15 is started, and the placement plate 12 can be sent out a part by the first electric slide rail 15. Then, the electric cylinder 7 is started again, so that the electric cylinder 7 drives the sliding plate 6 to continue to move downward. At this time, the limiting plate 9 limits the placement plate 12, so that the position of the placement plate 12 remains relatively unchanged. Thus, the clamping relationship between the clamping groove 18 and the clamping block 17 is lost, and the placement plate 12 can be manually pulled out, which is convenient for loading and unloading the leather on the placement plate 12.

[0039] When loading, the placement plate 12 is pushed into the housing 1 for a part. At this time, the electric cylinder 7 is started, and the sliding plate 6 can be driven to slide upward, so that the clamping block 17 enters the clamping groove 18, and a clamping relationship is generated between the clamping groove 18 and the clamping block 17. Thus, at this time, the placement plate 12 can be driven to slide by the first electric slide rail 15 until the placement plate 12 completely enters the housing 1. Then, the electric cylinder 7 is started, so that the electric cylinder 7 pushes the placement plate 12 upward until it contacts the baffle 19, and the leather can be cut, improving the work efficiency and achieving a better positioning effect.

[0040] The air extraction structure includes an air extraction pump 3 fixed in the housing 1. An air extraction pipe 4 is fixed at the intake end of the air extraction pump 3. A first cavity 10 is formed in the sliding plate 6, and the first cavity 10 is communicated with the air extraction pipe 4. An air outlet pipe 5 is fixed at the outlet end of the air extraction pump 3, and the air outlet pipe 5 is communicated with the outside of the housing 1. The communication structure includes a plurality of communication pipes 11 fixed on the sliding plate 6. A second cavity 40 is formed in the placement plate 12, and the second cavity 40 is communicated with the air intake holes 14. A plurality of through holes 13 are formed in the second cavity 40, and the through holes 13 correspond to the communication pipes 11. A filter screen is fixed at the end of the communication pipe 11.

[0041] Specifically, when the air extraction pump 3 is started, the air extraction pump 3 extracts air, so as to extract the air in the first cavity 10 through the air extraction pipe 4, and then extract the air in the second cavity 40 through the communication pipes 11. Thus, a negative pressure environment can be generated in the second cavity 40, and the leather can be adsorbed and fixed through the air intake holes 14, ensuring the stability of the leather, preventing the leather from moving during cutting, thus ensuring the success rate of leather cutting, preventing the leather from contacting the laser cutting head 30, preventing the leather from being burned, and the air in the cutting process can be extracted through the air intake holes 14 that do not contact the leather, so as to suck the smoke generated during cutting, preventing the smoke from polluting the air, and filtering the smoke through the filter screen to prevent the air extraction pump 3 from being blocked.

[0042] When the limit plate 9 contacts the placement plate 12, the electric cylinder 7 is started, so that the electric cylinder 7 drives the sliding plate 6 to continue moving downward. At this time, the connecting pipe 11 is withdrawn from the through hole 13, so that the through hole 13 is in an exposed state at this time. After the leather is disassembled, the soot filtered in the second cavity 40 can be cleaned through the through hole 13, thereby preventing the soot from accumulating and ensuring the effect of air extraction and filtration.

[0043] On both sides inside the housing 1, a second electric slide rail 23 is fixed. The output end of the second electric slide rail 23 is fixed with a third slider 24. A third electric slide rail 25 is fixed between the two third sliders 24. The output end of the third electric slide rail 25 is fixed with a fourth slider 26. A first linear motor 27 is fixed on the fourth slider 26. The output end of the first linear motor 27 is fixedly connected to the shielding cover 28. A laser cutting head 30 is fixed inside the shielding cover 28.

[0044] Specifically, starting the second electric slide rail 23 can drive the third slider 24 to move, thereby driving the third electric slide rail 25 to move. Starting the third electric slide rail 25 can drive the fourth slider 26 to move, thereby driving the laser cutting head 30 to move, which is convenient for the laser cutting head 30 to perform cutting. Different patterns can be formed on the leather by cutting with the laser cutting head 30. Starting the first linear motor 27 can drive the shielding cover 28 and the laser cutting head 30 to move through the first linear motor 27, so that the distance between the laser cutting head 30 and the leather can be adjusted, preventing the laser cutting head 30 from contacting the leather, ensuring the cutting effect on the leather, and the smoke generated during the cutting of the laser cutting head 30 can be blocked by the shielding cover 28, facilitating the centralized extraction of the smoke, improving the cleaning efficiency of the smoke, and preventing the smoke from overflowing and polluting the air environment.

[0045] Leather is placed on the placement plate 12. A plurality of balls 29 are rotatably fitted under the shielding cover 28. The balls 29 are located under the laser cutting head 30 and are in contact with the leather. Connecting pipes 32 are fixed on both sides of the shielding cover 28. The connecting pipes 32 are communicated with the shielding cover 28 and the air extraction head 31. The connecting pipes 32 are flexible hoses.

[0046] Specifically, the balls 29 are directly in contact with the leather, which can press down the leather and play a certain limiting and fixing effect on the leather, preventing the leather from moving during the cutting process, and can limit the laser cutting head 30 through the balls 29, preventing the laser cutting head 30 from directly contacting the leather, thereby preventing the leather from being burned and protecting the leather, reducing the damage rate of the leather.

[0047] The air extraction head 31 is of a horn-shaped structure. Fifth sliders 34 are slidably fitted on both sides inside the housing 1. The fifth sliders 34 are fixedly connected to the air extraction head 31. The air extraction head 31 is located above the air inlet hole 14. Third sliding grooves 33 are opened on both sides inside the housing 1, and the third sliding grooves 33 correspond to the fifth sliders 34.

[0048] Specifically, the air pump 3 extracts the air in the first cavity 10 through the air extraction pipe 4, thereby extracting the air in the second cavity 40 through the connecting pipe 11, and extracting the air through the air intake hole 14, thereby extracting the smoke in the shielding cover 28 through the air extraction head 31 and the connecting pipe 32. And when the shielding cover 28 slides, at this time, the connecting pipe 32 can be pulled by the shielding cover 28, thereby pulling the air extraction head 31, so that the position of the fifth slider 34 in the third chute 33 is changed, thereby changing the position of the air extraction head 31 to ensure the air extraction effect of the air extraction head 31.

[0049] Feeding ports 41 and discharging ports 42 are respectively formed on both sides of the housing 1. A baffle 19 is fixed in the housing 1. The baffle 19 is in a loop structure. The baffle 19 is located above the placing plate 12. The feeding port 41 corresponds to the anti-crease structure. The two auxiliary structures are respectively located on one side of the feeding port 41 and the discharging port 42. The anti-crease structure includes a pressing plate 38 slidably fitted in the feeding port 41. A second linear motor 37 is fixed in the feeding port 41. The output end of the second linear motor 37 is fixedly connected to the pressing plate 38. A plurality of pressure sensors 39 are fixed on the side of the pressing plate 38 away from the housing 1. An alarm is installed on the housing 1. The alarm is connected to the pressure sensors 39 through a data line.

[0050] Specifically, feeding can be performed through the feeding port 41. When feeding, the leather contacts the pressing plate 38. The second linear motor 37 is started, and the position of the pressing plate 38 can be adjusted according to the thickness of the leather. When the leather wrinkles, at this time, the leather will contact the pressure sensor 39, so that the pressure sensor 39 generates a signal and sends it to the alarm, and the alarm gives an alarm, thereby reminding the staff to adjust the wrinkles in time, so as to ensure the accuracy of leather cutting, prevent cutting failure, improve the success rate of leather cutting, and prevent the wrinkled leather from contacting the laser cutting head 30.

[0051] The top plate 35 is hinged to the top of the housing 1. A plurality of air intake holes 36 are formed in the top plate 35. A groove 43 is formed in the top of the housing 1. The groove 43 corresponds to the top plate 35.

[0052] Specifically, the top plate 35 can shield the top of the housing 1 to prevent the rapid diffusion of a large amount of smoke, which may cause air pollution, thereby ensuring the health of the staff and ensuring the effect of smoke absorption.

[0053] Workflow: Place the leather on the placement plate 12, then push the placement plate 12 into the housing 1 partially. The leather comes into contact with the pressing plate 38. Start the second linear motor 37 to adjust the position of the pressing plate 38 according to the thickness of the leather. When the leather wrinkles, the leather will come into contact with the pressure sensor 39 at this time, so that the pressure sensor 39 generates a signal and sends it to the alarm. When there are no wrinkles, start the electric cylinder 7 at this time, which can drive the sliding plate 6 to slide upward, so that the clamping block 17 enters the clamping groove 18, and the connecting pipe 11 enters the through hole 13. A clamping connection relationship is generated between the clamping groove 18 and the clamping block 17. Thus, at this time, the placement plate 12 can be driven to slide by the first electric slide rail 15 until the placement plate 12 completely enters the housing 1. Then continue to start the electric cylinder 7, so that the sliding plate 6 drives the placement plate 12 to slide upward until the placement plate 12 comes into contact with the baffle 19. At this time, the ball 29 directly contacts the leather, so that the leather can be pressed down, playing a certain limiting and fixing effect on the leather to prevent the leather from moving during the cutting process. And the laser cutting head 30 can be limited by the ball 29 to prevent the laser cutting head 30 from directly contacting the leather. Start the laser cutting head 30 to cut the leather. Start the second electric slide rail 23 to drive the third slider 24 to move, thereby driving the third electric slide rail 25 to move. Start the third electric slide rail 25 to drive the fourth slider 26 to move, thereby driving the laser cutting head 30 to move, so that the laser cutting head 30 cuts the leather into different patterns. At the same time, start the air extraction pump 3. The air extraction pump 3 extracts the air in the first cavity 10 through the air extraction pipe 4, and thus extracts the air in the second cavity 40 through the connecting pipe 11, creating a negative pressure environment in the second cavity 40. Thus, the leather is adsorbed and fixed through the air inlet hole 14. And the second cavity 40 is evacuated through the air inlet hole 14 that does not contact the leather, so that the smoke can be sucked. At the same time, the air inlet hole 14 extracts the smoke in the shielding cover 28 through the air extraction head 31 and the connecting pipe 32, quickly cleaning the smoke generated by the cutting. Until after the cutting is completed, start the electric cylinder 7 to drive the placement plate 12 to move to the discharge port 42. At this time, the limiting plate 9 comes into contact with the placement plate 12. Then start the first electric slide rail 15 to send out a part of the placement plate 12 through the first electric slide rail 15. Then start the electric cylinder 7 again to drive the sliding plate 6 to continue moving downward. At this time, the limiting plate 9 limits the placement plate 12, so that the position of the placement plate 12 remains relatively unchanged. Thus, the clamping connection relationship between the clamping groove 18 and the clamping block 17 is lost, and the connecting pipe 11 is pulled out of the through hole 13, and the placement plate 12 can be manually pulled out to unload the leather after cutting is completed.

[0054] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
