[0031] This invention provides a fully automatic leather cutting device, such as... Figure 1-10 As shown, it includes a base plate 11, a top plate 12, an inner cavity 13, a first slot 14, a transmission shaft 15, a first opening 16, a flow limiting block 17, a negative pressure device 18, a first guide channel 19, a second guide channel 20, a flow baffle 21, a side plate 22, a second slot 23, a third slot 24, a first slider 25, a traveling wheel 26, a support rod 27, a hot melt gun 28, a horizontal sliding rod 29, a fourth slot 30, an electric telescopic rod 31, an electric steering rod 32, a blade 33, a wax spray gun 34, a fifth slot 40, a limiting block 41, a spring 42, a second slider 43, a connecting plate 44, and a second limiting plate 45.

[0032] like Figure 1-10 As shown, the bottom plate 11 and the top plate 12 surround an inner cavity 13. The top of the top plate 12 has a first slot 14, and a transmission shaft 15 is rotatably connected in the first slot 14. Several first openings 16 are opened on one inclined surface of the top plate 12. A flow limiting block 17 is fixedly installed in the first opening 16. A negative pressure device 18 is installed at one end of the first opening 16 near the inner cavity 13. Side plates 22 are fixedly connected to both sides of the top plate 12. A hot melt gun 28 and a cutting assembly are slidably connected in the side plates 22. The cutting assembly includes a wax spray gun 34, which is used to spray wax oil. Anti-rolling components are also slidably installed on both sides of the top plate 12.

[0033] The cutting assembly also includes a horizontal slide bar 29 and an electric telescopic rod 31. A fourth slot 30 is provided on the horizontal slide bar 29. The electric telescopic rod 31 is slidably connected to the fourth slot 30. An electric steering rod 32 is rotatably connected to the electric telescopic rod 31. A blade 33 is fixedly connected to the electric steering rod 32. A wax spray gun 34 is fixedly connected to the electric telescopic rod 31.

[0034] A second slot 23 is provided in the side plate 22, and a third slot 24 is provided on one side wall of the second slot 23. Two first sliders 25 are slidably connected in the second slot 23. A traveling wheel 26 is rotatably connected to the first slider 25. The traveling wheel 26 is tumbledly connected to the third slot 24. A support rod 27 is fixedly connected to the first slider 25, and one of the support rods 27 is fixedly connected to the horizontal slide rod 29.

[0035] A second guide groove 20 is provided between the ends of the first opening 16 away from the inner cavity 13. A first guide groove 19 is provided at the junction of the top plate 12 and the bottom plate 11. A second guide groove 20 is also provided between the first opening 16 near the first guide groove 19 and the first guide groove 19. A baffle plate 21 is fixedly covered on the second guide groove 20. The second guide groove 20 is made of a heat-conducting metal sheet.

[0036] The second guide channel 20 ensures that after the hot melt gun 28 melts the wax solidified in the top plate 12 and the first opening 16, the wax flows along the second guide channel 20 into the first guide channel 19 and is discharged. The baffle plate 21 ensures that when the negative pressure device 18 generates suction in the first opening 16, the suction force of the negative pressure device 18 on the leather will not escape from the second guide channel 20. The flow limiting block 17 in the first opening 16 reduces the risk of wax being sucked into the negative pressure device 18.

[0037] The first openings 16 are divided into several columns, and the first openings 16 in the columns are equally spaced. The first openings 16 in the same column are equally spaced. The distance between the first openings 16 in the same column can also be gradually increased along the direction from the transmission shaft 15 to the first guide groove 19. The length of the second groove 23 is greater than the distance between the first openings 16 at both ends of the same column.

[0038] The anti-rolling assembly includes a connecting plate 44 and a second limiting plate 45. Two fifth slots 40 are provided on both sides of the top plate 12. A limiting block 41 is fixedly connected in the fifth slot 40. A spring 42 is fixedly connected to the limiting block 41. A second slider 43 is fixedly connected to the end of the spring 42 away from the limiting block 41. The second slider 43 is fixedly connected to the connecting plate 44. The second limiting plate 45 is fixedly connected to the connecting plate 44. An arc surface is provided on the second limiting plate 45, and the arc surface is adapted to the transmission shaft 15.

[0039] It is worth noting that the transmission shaft 15, the travel wheel 26, the electric telescopic rod 31 and the electric steering rod 32 are all equipped with drive motors, and the way in which the electric telescopic rod 31 slides relative to the fourth slot 30 is existing technology.

[0040] When this solution performs fully automatic leather cutting, firstly, the transmission shaft 15 is started. The transmission shaft 15 rotates and transfers the leather from one side of the top plate 12 to the side of the top plate 12 where the first opening 16 is provided. At this time, the spring 42 provides tension to the second slider 43. The second slider 43, through the connecting plate 44, makes the second limiting plate 45 fit tightly against the side of the leather, thereby preventing the side of the leather from rolling up. Then, the negative pressure device 18 is started. The negative pressure device 18 provides suction to the flow limiting block 17 in the first opening 16. The first opening 16 adsorbs the leather onto the top plate 12.

[0041] Then, the travel wheel 26, electric telescopic rod 31 and electric steering rod 32 are activated. The travel wheel 26 drives the first slider 25 to slide along the second slot 23. The first slider 25 drives the horizontal slide rod 29 to slide along the extension direction of the second slot 23 through the support rod 27. The electric telescopic rod 31 slides relative to the fourth slot 30. The electric steering rod 32 rotates relative to the electric telescopic rod 31. The electric telescopic rod 31 extends and retracts. The electric steering rod 32 adjusts the blade 33 to above the leather to cut the leather. The wax spray gun 34 sprays wax oil onto the cut surface of the leather.

[0042] Finally, after the device cuts the leather multiple times, the wax oil tends to solidify on the top plate 12 and may block the first opening 16, thus preventing the first opening 16 from adsorbing the leather onto the top plate 12. Therefore, it is necessary to activate the traveling wheel 26 connected to the hot melt gun 28. The traveling wheel 26 drives the first slider 25 to slide along the second slot 23. The first slider 25 drives the hot melt gun 28 to slide along the extension direction of the second slot 23 through the support rod 27. The hot melt gun 28 melts the wax oil on the surface of the top plate 12 and in the first opening 16. The wax oil in the first opening 16 flows along the second guide groove 20 to the first guide groove 19 and is discharged.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
