[0026] The beneficial effects of the present invention are:

[0027] 1. Before cutting the leather raw material, wrinkles will be generated on the surface of the leather raw material due to transportation or processing. The existing leather raw material cutting device directly places the leather raw material on the cutting table, and is unable to process the wrinkles of the leather raw material, which makes it easy to make errors during cutting. Due to the nature of the leather raw material itself, the wrinkles on its surface can be removed after heating. The present application can heat the surface of the leather raw material by providing a heating cylinder, and use the heat to remove the wrinkles. The leather raw material can be wiped and dusted by a wiping sponge, thereby ensuring the cleanliness of the surface of the leather raw material. At the same time, the expansion bladder will expand after being heated. The expanded expansion bladder can make the wiping sponge better fit the surface of the leather raw material, thereby improving the cleaning effect of the leather raw material.

[0028] 2. The rotating plate and the stationary plate can separate the inside of the air box into two chambers. When the rotating plate rotates along the inside of the air box, the gas in one of the chambers is introduced into the air cylinder by extrusion, thereby driving the suction cup nozzle toward the surface of the leather material. The other chamber uses negative pressure to extract the gas between the suction cup nozzle and the leather material, and at the same time wipes the leather material clean with a sponge, so that the suction cup nozzle fixes the leather material by vacuum adsorption.

[0029] 3. When the leather material needs to be cut, the lead-out hole on the heating cylinder tensions the leather material during the rotation process, thereby ensuring that the surface of the leather material is always in a flat state during the cutting process.

[0030] 4. By providing a detachable cam, the conical block can be moved, so that the scissor arm, telescopic arm one and telescopic arm two drive the suction cup nozzle to swing during the folding and unfolding process. By setting the detachable cam to be detachable, the installation quantity of the detachable cam on the adjusting disk can be adjusted, and then the time that the suction cup nozzle stays at a specific position can be set. At the same time, by stacking the detachable cams, the thickness of the detachable cams after stacking can be adjusted. The thickness of the detachable cams after stacking is different, and the degree of squeezing of the conical block is also different, and then the position where the suction cup nozzle stays can be adjusted, so that flexible wrinkle removal can be performed according to the different specifications of the leather raw materials and the different positions of the wrinkles.

[0031] 5. Taking advantage of the fact that the ratchet ring can only rotate in one direction along the one-way tooth surface, the leather raw material can be transported when the conveyor roller 1 and the conveyor roller 2 rotate in opposite directions. When the conveyor roller 1 and the conveyor roller 2 rotate in the same direction, the conveyor roller 1 drives the heating cylinder and the outlet hole to rotate through the belt and the pulley to tension the leather raw material.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0049] Embodiment 1:

[0050] A raw material cutting device for handbag leather processing, such as Figure 1-12 As shown, it includes a base 1 and a wrinkle removal part, and the wrinkle removal part includes:

[0051] The second vertical plate 12 is fixed to the top outer wall of the base 1 by bolts, and the inner wall of the through hole opened on the surface of the second vertical plate 12 is rotatably connected to the driving rod 33, and the outer wall of the circumference of the driving rod 33 is welded with a rotating plate 32;

[0052] The third vertical plate 13 is fixed to the top outer wall of the base 1 by bolts, and an air box 31 is fixed to the outer wall of one side of the third vertical plate 13 by bolts, and a stationary plate 34 is welded to the inner wall of the circumference of the air box 31;

[0053] Heating tube 25: It is fixed to one end of driving rod 33 by a pin, and two outlet holes 35 are provided on the outer circumferential wall of heating tube 25, and an expansion bag 58 is bonded to the inner surface of outlet hole 35, and a wiping sponge 59 is bonded to the surface of expansion bag 58;

[0054] Gas cylinder 27: It is embedded in the inner wall of the through hole opened at the top of the heating cylinder 25, and a three-way solenoid valve 30 is connected to the top of the gas cylinder 27 through a thread, and the outlet of the three-way solenoid valve 30 and the circumferential outer wall of the gas box 31 are connected through an air pipe 26;

[0055] The guide rod 46 is slidably connected to the inner wall of the through hole opened at the bottom of the gas cylinder 27, and the top of the guide rod 46 is fixed with a piston plate 44 by a pin, and a spring 45 is fixed between the top of the piston plate 44 and the inner wall of the top of the gas cylinder 27 by a pin;

[0056] The regulating box 37 is fixed to the bottom of the guide rod 46 by a pin, and the inner wall of the bottom of the regulating box 37 is fixed with an air receiving plate 42 by screws, and the outer wall of one side of the air receiving plate 42 is connected with an inlet pipe 36 by a thread:

[0057] Suction cup type nozzle 56: It is connected to the bottom of the air receiving plate 42 through a hose, and a folding component for supporting the suction cup type nozzle 56 is provided inside the regulating box 37;

[0058] Three-way solenoid valve 2 53: It is connected to one end of the inlet pipe 36 through a thread, and an inlet of the three-way solenoid valve 2 53 and the outer wall of the circumference of the air box 31 are connected through an exhaust pipe 54;

[0059] Upper support plate 38: fixed to the bottom inner wall of heating tube 25 by bolts;

[0060] Before cutting the leather raw material, in order to ensure the accuracy of the leather raw material during cutting, it is necessary to remove wrinkles on its surface to reduce wrinkles on the surface of the leather raw material. Two groups of outlet holes 35 are provided on the circumferential outer wall of the air cylinder 27 so that the leather raw material to be cut can be inserted through the inside of the air cylinder 27. By connecting the two inlets of the three-way solenoid valve 53 and the hot air blower, hot air can enter the inside of the heating cylinder 25 through the inlet pipe 36. By bonding a wiping sponge 59 on the surface of the expansion bag 58, the leather raw material can be wiped and dusted by the wiping sponge 59, thereby ensuring the cleanliness of the surface of the leather raw material. At the same time, the expansion bag 58 will expand after being heated. The expanded expansion bag 58 can make the wiping sponge 59 better fit the surface of the leather raw material, thereby improving the cleaning effect of the wiping sponge 59. When the leather raw material enters the inside of the heating cylinder 25, the heat can be used to effectively remove wrinkles on the surface of the leather raw material.

[0061] The hot air first enters the air receiving plate 42 through the inlet pipe 36, and finally is discharged into the heating cylinder 25 through the suction cup nozzle 56. In the initial stage, the leather material is placed between the adjustment box 37 and the upper support plate 38 after entering the heating cylinder 25. By setting a certain distance between the upper support plate 38 and the leather material, it is prevented that the hot air directly acts on the surface of the leather material, thereby causing damage to the leather material. When the leather material needs to be cut, the leather material needs to be fixed to ensure the stability of the leather material during cutting. At this time, the driving rod 33 is driven, and the driving rod 33 is driven during the rotation process. The rotating plate 32 rotates counterclockwise along the direction of the stationary plate 34. During the rotation process, the rotating plate 32 continuously squeezes the gas in the chamber between it and the stationary plate 34. During this process, the valve 1 of the first outlet of the three-way solenoid valve 1 30 is opened, and the valve 2 of the second outlet is closed. The gas can enter the spring 3 45 through the air pipe 26 and the valve 1 to push the piston plate 44, so that the suction cup type nozzle 56 can finally be pressed on the upper surface of the leather material. After the suction cup type nozzle 56 is pressed on the upper surface of the leather material, the valve 1 is closed and the valve 2 is opened, thereby limiting the position of the guide rod 46 relative to the spring 3 45.

[0062] As the rotating plate 32 rotates counterclockwise along the stationary plate 34, the rotating plate 32 also absorbs the gas in another chamber formed between it and the stationary plate 34. During this process, the valve three of the first inlet of the three-way solenoid valve 2 53 is opened and the valve four of the second inlet is closed, so that the rotating plate 32 can extract the gas inside the gas disk 42 and the suction cup type nozzle 56 through the exhaust pipe 54. The gas in the suction cup type nozzle 56 is in a vacuum state after extraction, so that the suction cup type nozzle 56 can fix the leather raw material by vacuum adsorption, thereby ensuring the stability of the leather raw material during cutting.

[0063] Further, a vertical plate 4 15 is fixed to the outer wall of the top of the base 1 by bolts, and a conveying roller 9 is rotatably connected to the inner wall of the through hole opened on the surface of the vertical plate 4 15, a driving motor 2 14 is fixed to the outer wall of one side of the vertical plate 4 15 by bolts, and the output end of the driving motor 2 14 is connected to one end of the conveying roller 9 through a coupling, an electric telescopic rod 55 is fixed to the outer wall of the top of the base 1 by bolts, and a bracket 2 8 is fixed to the output end of the electric telescopic rod 55 by a pin, and a conveying roller 2 10 is rotatably connected between the inner walls on both sides of the bracket 2 8, and a driving motor 6 is fixed to the outer wall of one side of the bracket 2 8 by bolts, and the output end of the driving motor 6 is connected to one end of the conveying roller 2 10 through a coupling;

[0064] By providing an electric telescopic rod 55, the spacing distance between the conveying roller 2 10 and the conveying roller 1 9 can be adjusted, so that when leather materials of different thicknesses are cut, a certain friction force can be maintained between the leather materials and the conveying rollers 1 9 and 10. By providing a drive motor 2 14, the conveying roller 1 9 can be driven to rotate, and the drive motor 1 6 can be used to drive the conveying roller 2 10 to rotate. When the conveying rollers 1 9 and 10 rotate in opposite directions, the conveying rollers 1 9 and 10 can convey the leather materials to be cut by friction, and the output ends of the drive motor 1 6 and the drive motor 2 14 both have a self-locking function.

[0065] Furthermore, a vertical plate 11 is fixed to the top outer wall of the base 1 by bolts, and a limiting plate 21 is welded to the outer wall of one side of the vertical plate 11, a rotating column 20 is rotatably connected to the inner wall of a through hole opened on the surface of the vertical plate 11, and the circumferential outer wall of the rotating column 20 and the circumferential outer wall of the driving rod 33 are driven by a belt and a pulley, a resisting plate 22 is fixed to the circumferential outer wall of the rotating column 20 by a pin, and a cushion block 19 is fixed to one end of the rotating column 20 by a pin, a T-shaped rod 17 is slidably connected to the through hole opened on the top of the cushion block 19, a spring 18 is fixed between the bottom inner wall of the T-shaped rod 17 and the top inner wall of the cushion block 19 by a pin, and a one-way tooth 24 is fixed to one end of the T-shaped rod 17 by a pin; a connecting frame 16 is fixed to one end of the conveying roller 9 by a pin, and a ratchet ring 23 adapted to the one-way tooth 24 is fixed to one end of the connecting frame 16 by bolts;

[0066] When the driving motor 2 14 drives the conveying roller 1 9 to rotate and convey the leather raw material, the thorn ring 23 moves along the Figure 4 As shown in the figure, the contact plate 22 rotates counterclockwise. At this time, the contact plate 22 remains stationary under the limiting action of the limiting plate 21, and the elastic action of the spring 18 makes the one-way clamping tooth 24 bounce along the surface of the ratchet ring 23. During this process, the rotating column 20 and the heating cylinder 25 remain stationary. When the leather material is conveyed to a certain length and a certain pattern and shape needs to be cut on the surface of the leather material between the conveying roller 9 and the heating cylinder 25, the output end of the driving motor 2 14 is reversed by controlling the driving motor 2. At this time, the ratchet ring 23 moves along Figure 4As shown, the contact plate 22 rotates clockwise, and the bottom of the contact plate 22 is arc-shaped, so that the contact plate 22 can rotate along the surface of the limit plate 21. The ratchet ring 23 drives the one-way clamping tooth 24 to rotate during the clockwise rotation. The driving rod 33 can be rotated by the transmission effect of the belt and the pulley. The rotation of the driving rod 33 is used to realize the vacuum adsorption of the suction cup type nozzle 56 on the surface of the leather raw material. In this process, the rotation direction of the output end of the driving motor 16 remains unchanged, and the output ends of the driving motor 16 and the output ends of the driving motor 2 14 have the same rotation direction, so that the leather raw material can be limited. Due to the effect of the driving rod 33, when the driving rod 33 drives the heating cylinder 25 to rotate, while the leather material is fixed by the vacuum suction of the suction cup nozzle 56, the linear distance of the lead-out hole 35 relative to the axis of the conveying roller 9 gradually increases during the rotation of the lead-out hole 35 along the circumferential direction, so that the leather material is tensioned during the rotation, and at this time, the output ends of the driving motor 1 6 and the driving motor 2 14 are self-locking, thereby fixing the other end of the leather material. Since the leather material has a certain ductility and elasticity, the leather material is tensioned to ensure that the leather material remains flat during the cutting process.

[0067] Furthermore, the folding assembly includes a slider 48 and a drive shaft 49, the slider 48 is slidably connected to the inner wall of the slide groove opened at one end of the air receiving plate 42, the drive shaft 49 is fixed to the bottom of the slider 48 by a pin, and the circumferential outer wall of the drive shaft 49 is rotatably connected to the telescopic arm 2 50, the other end of the air receiving plate 42 is fixed with a rotating rod by a pin, the circumferential outer wall of the rotating rod is rotatably connected to the telescopic arm 1 43, and the telescopic arm 1 43 and the telescopic arm 2 50 are rotatably connected by a plurality of scissor arms 41, and the surface of the scissor arms 41 is provided with through holes adapted to the outer wall of the suction cup type nozzle 56, one end of the slider 48 is fixed with a reciprocating rod 47 by a pin, and one end of the reciprocating rod 47 is fixed with a conical block by a pin 39, a spring 2 40 is fixed between the inner wall of one side of the conical block 39 and the outer wall of one side of the adjusting box 37 by a pin, a vertical plate 5 29 is fixed to the outer wall of the top of the base 1 by bolts, an adjusting disk 60 is rotatably connected to the inner wall of the through hole opened on the surface of the vertical plate 5 29, a swing motor 57 is fixed to the outer wall of one side of the vertical plate 5 29 by bolts, and the output end of the swing motor 57 and one end of the adjusting disk 60 are connected by a coupling, a positioning rod 61 is welded to the outer wall of one side of the adjusting disk 60, a detachable cam 28 is inserted into the outer wall of the positioning rod 61, and a pressure plate 62 is inserted into one end of the positioning rod 61, and the pressure plate 62 and the adjusting disk 60 are locked by a locking screw 63;

[0068] The adjusting disk 60 can be rotated by the driving action of the swing motor 57. The detachable cam 28 can be installed on the surface of the adjusting disk 60 by inserting it through the positioning rod 61. The positioning rod 61 is a square structure, which can ensure the stability of the detachable cam 28 after insertion. The pressure plate 62 and the adjusting disk 60 can be fixed by the locking screw 63, so as to ensure the stability of the detachable cam 28 after installation. By providing multiple groups of positioning rods 61, the detachable cam 28 can be installed by plugging. The edge of the detachable cam 28 is arc-shaped, so that During the rotation of the disassembly cam 28, the conical block 39 can be squeezed, so that the slider 48 drives the telescopic arm 2 50 during the sliding process along the slide groove opened at the bottom of the air receiving plate 42, so that the telescopic arm 2 50 and the multiple scissor arms 41 perform telescopic movement. When one end of the conical block 39 gradually moves along the edge position of the disassembly cam 28 to the plane of the side wall of the disassembly cam 28, the conical block 39 will slide along the plane position of the side wall of the disassembly cam 28. During this process, the conical block 39 will not be displaced in the horizontal direction, so that the suction cup type nozzle 56 can be at a specific position. The purpose of this is that when it is necessary to remove wrinkles at a specific position on the surface of the leather material, such as a joint, the time for the suction cup nozzle 56 to stay can be extended, so that the leather material can be better wrinkled by the hot air derived from the suction cup nozzle 56. By setting the detachable cam 28 to be detachable, the installation quantity of the detachable cam 28 can be adjusted, and then the time for the suction cup nozzle 56 to stay at a specific position can be set. At the same time, by stacking the detachable cams 28, the thickness of the detachable cams 28 after being stacked can be adjusted, and then the The suction cup nozzle 56 can be adjusted at the position where it stops, so as to facilitate flexible wrinkle removal of leather materials with different specifications and wrinkle positions. At the same time, by setting the telescopic arm 1 43 at a fixed position at one end of the adjustment box 37, the telescopic arm 2 50 is set to be able to slide along the slide groove on the surface of the air receiving plate 42 through the slider 48, so that the telescopic movement between the telescopic arm 2 50 and the multiple scissor arms 41 can be achieved by only using a set of swing motors 57 and adjustment plates 60, and at the same time, the moving distances between the multiple suction cup nozzles 56 can be ensured to be the same, so that hot air can be discharged through the suction cup nozzles 56.

[0069] Furthermore, a mounting plate 52 is fixed to the top outer wall of the base 1 by bolts, a screw guide rail 2 is fixed to the outer wall of one side of the mounting plate 52 by bolts, the output end of the screw guide rail 2 is slidably connected to the screw guide rail 2 3, and the output end of the screw guide rail 2 3 is slidably connected to the telescopic vibrating cutter head 51;

[0070] By providing the lead screw guide rail 1 2 and the lead screw guide rail 2 3, the position of the telescopic vibrating cutter head 51 in the horizontal and vertical directions can be adjusted, so that the telescopic vibrating cutter head 51 can cut the set pattern or shape on the surface of the leather material through CNC after the leather material is tensioned.

[0071] Furthermore, the outer wall of one side of the bracket 2 8 is fixed with the bracket 1 5 by bolts, and the inner walls on both sides of the bracket 1 5 are rotatably connected with the same limiting roller 4;

[0072] By setting a limiting roller 4, the leather raw material can be transported and guided in cooperation with the conveying roller 9 during the conveying process. The height of the limiting roller 4 is flush with the height of the conveying roller 9. When the lead-out hole 35 tightens the leather raw material during rotation, the height of the lead-out hole 35 gradually becomes lower than the limiting roller 4 and the conveying roller 9, so that the surface of the leather raw material can be tightened on the top of the limiting roller 4.

[0073] Furthermore, a cutting table 7 is fixed to the top outer wall of the base 1 by bolts;

[0074] By providing a cutting table 7, one end of the leather material can be supported during transportation. When the telescopic vibrating blade 51 is cutting the leather material, it can cut a certain shape or pattern on the surface of the leather material according to actual needs, and can also cut a certain length of the leather material according to needs. When it is necessary to cut a certain length of leather material, the cutting table 7 is used to support the leather material at the end, so that the telescopic vibrating blade 51 moves to the upper surface of the leather material for cutting. At the same time, the leather material is suspended in the air during transportation, so that when a certain shape or pattern is cut on the surface of the leather material, the cut leather material falls under the action of gravity, which is convenient for collecting the leather material.

[0075] When the present embodiment is in use, when it is necessary to cut a certain pattern or shape on the surface of the leather raw material, the rolled leather raw material is first installed on the reel, and then one end of the leather raw material is passed through the two outlet holes 35 in turn, and then it is moved to the gap between the conveying roller 1 9 and the conveying roller 2 10, and the height of the conveying roller 2 10 is adjusted by the electric telescopic rod 55, so that the conveying roller 1 9 and the conveying roller 2 10 press the leather raw material by friction. In the process of the leather raw material passing through the two outlet holes 35, the two inlets of the three-way solenoid valve 2 53 are connected to the hot air blower, so that the hot air blower blows hot air into the heating cylinder 25, so that the heat is used to process the wrinkles on the surface of the leather raw material during transportation or production. At the same time, the sponge bonded to the surface of the outlet hole 35 can clean the floating dust on the surface of the leather raw material. When the leather raw material needs to be cut after wrinkle removal, the drive motor 2 14 is controlled to make it The output end is reversed relative to the initial stage, and the one-way tooth 24 is driven to rotate by the ratchet ring 23. Under the transmission action of the pulley and the belt, the driving rod 33 can drive the rotating plate 32 to rotate along the inner wall of the air box 31. During this process, the guide rod 46 can drive the suction cup nozzle 56 to gradually approach the surface of the leather material under the push of the gas. When the suction cup nozzle 56 and the surface of the leather material are in contact and fit, the negative pressure can be used to extract the gas between the suction cup nozzle 56 and the leather material, so that the suction cup nozzle 56 can adsorb and fix the surface of the leather material through vacuum. At the same time, the heating cylinder 25 continuously tightens the leather material during the rotation process, so as to ensure the flatness of the leather material after fixation. Then the lead screw slide 1 2 and the lead screw slide 2 3 are used to drive the telescopic vibrating cutter head 51 to move, and the telescopic vibrating cutter head 51 cuts a certain pattern or shape on the surface of the leather material through CNC.

[0076] The above is a preferred specific embodiment of the present invention, but it is not the only specific embodiment of the present invention. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the existing technology or public common sense within the spirit and principle of the present invention should be covered by the protection scope of the present invention.
