Description

Technical Field

[0001] The present invention relates to the technical field of leather production equipment, and in particular to leather production equipment and technology. Background Art

[0002] Leather is a denatured, non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. Leather is made of natural protein fibers tightly woven in three-dimensional space, and has a special grain layer on its surface. It is one of the main materials for making clothing and shoes. In order to improve the beauty of leather, it is usually necessary to use a leather embossing machine to emboss the leather.

The matching component 5 includes a U-shaped plate and a roller rotatably installed in its inner cavity, and the outer surface of the roller contacts the lower surface of the leather passing through, so that the movement of the leather is smoother;

[0037] Next, the front and rear ends of the discharging block 2 are fixed with embossing parts 3, which are used to emboss the leather. The upper end of the horizontal part of the supporting block 1 is fixed with a lifting part 4 adapted to the embossing part 3. The lifting part 4 can adjust the embossing distance between the embossing part 3 and the lifting part 4 according to the thickness and material of the leather.

[0038] In addition, a cylinder is fixed at the front end of the discharging block 2, and a mounting plate 6 is fixed at the output end of the cylinder. An adjusting component 9 is provided at the rear end of the mounting plate 6. The adjusting component 9 is rotatably installed at the rear end of the mounting plate 6, and is used to adjust the winding diameter according to the material of the leather to wind the leather. A moving component 8 is fixed at the rear end of the mounting plate 6, and the moving component 8 is used to move the wound leather out. A pushing and unwinding component 7 matched with the adjusting component 9 is provided on the upper side of the moving component 8. The pushing and unwinding component 7 is slidably connected with the adjusting component 9. The pushing and unwinding component 7 cooperates with the moving component 8 to automatically unwind the leather wound by the adjusting component 9, thereby improving the production speed of the device.

[0039] Further, if Figure 2 As shown, the embossing component 3 includes two symmetrical connecting plates 30, and the two connecting plates 30 are respectively fixed to the front and rear ends of the discharge block 2, and the ends of the two connecting plates 30 close to each other are commonly provided with a connecting shaft, which passes through the two connecting plates 30 and is rotatably connected with the two connecting plates 30 at the penetration point, an embossing roller 34 is fixed to the outer surface of the connecting shaft, a face gear 32 is fixed to the rear end of the connecting shaft, a bracket 31 is fixed to the front end of the rear connecting plate 30, the connecting shaft passes through the bracket 31 and is slidably connected between the bracket 31, and the rotation of the connecting shaft will not affect the bracket 31, and a driving motor is fixed to the upper end of the horizontal part of the bracket 31, and a spur gear 33 meshing with the face gear 32 is fixed to the output end of the driving motor.

[0040] Further, if Figure 3 As shown, the lifting component 4 includes a lifting cylinder 40, which is fixed to the upper end of the horizontal part of the support block 1, and a U-shaped block 41 is fixed to the output end of the lifting cylinder 40. A connecting shaft is provided between the two vertical parts of the U-shaped block 41, and the connecting shaft passes through the two vertical parts of the U-shaped block 41 and is rotatably connected between the two vertical parts of the U-shaped block 41. A supporting roller 44 is fixed to the outer surface of the connecting shaft, and the supporting roller 44 is used to support the movement of the leather. A face gear 2 42 is fixed to the rear end of the connecting shaft, and two symmetrical baffles 45 are fixed to the upper end of the loading block 43, and the two baffles 45 are used to limit the position of the edge of the leather;

[0041] Among them, Figure 2 and Figure 3 As shown, the face gear 2 42 is meshed with the spur gear 33, and the spur gear 33 is meshed with the face gear 1 32 and the face gear 2 42. When stationary, the face gear 2 42 moves up and down and is still meshed with the spur gear 33. The spur gear 33 rotates, so that the face gear 1 32 and the face gear 2 42 rotate in opposite directions, and the embossing roller 34 and the supporting roller 44 also rotate in opposite directions, which is convenient for embossing and conveying leather;

[0042] Next, the two baffles 45 are fixed with a limiting assembly 46 at one end close to each other. The distance from the bottom end of the two limiting assemblies 46 close to the mating assembly 5 to the bottom wall of the inclined groove at the upper end of the discharge block 2 is kept the same as the distance from the embossing roller 34 to the support roller 44. The limiting assembly 46 includes a guide plate and a flattening wheel. The right side of the guide plate is inclined to prevent the warped leather from not moving to the inclined groove on the upper side of the discharge block 2. The left side of the guide plate is parallel to the bottom wall of the inclined groove, and the distance between the left side of the guide plate and the bottom wall of the inclined groove and the distance between the outer surface of the embossing roller 34 and the outer surface of the support roller 44 are always kept the same, so that the embossed leather can move along the inclined groove on the upper side of the discharge block 2 without warping.

[0043] Among them, Figure 4 As shown, a loading block 43 adapted to the support roller 44 is fixed to the upper ends of the two vertical parts of the U-shaped block 41, and the discharging block 2 is also adapted to the support roller 44. The loading block 43 and the discharging block 2 are provided with grooves adapted to the support roller 44 on one side close to the support roller 44 to prevent the support roller 44 from contacting the discharging block 2 and the loading block 43 when the support roller 44 is raised or lowered.

[0044] Embodiment 2

[0045] This embodiment further defines the unloading push component 7, the moving component 8 and the adjusting component 9 on the basis of the first embodiment, so as to achieve the purpose of adjusting the winding diameter according to the different materials of the leather to wind the leather and automatically unloading the leather after winding is completed.

[0046] Specifically, Figure 5 - Figure 7 As shown, the adjusting component 9 includes an output motor 90, which is fixed to the front end of the mounting plate 6, and a connecting rod 91 is fixed to the output end of the output motor 90, which penetrates the mounting plate 6 and is rotatably connected to the mounting plate 6 at the penetration point, and two symmetrical rings 92 are fixed to the outer surface of the connecting rod 91, and six circular array sliding grooves 93 are opened at one end of the two rings 92 close to each other, and the opening direction of the sliding grooves 93 is in the same straight line as the center of the rings 92, and the inner cavities of the six sliding grooves 93 are all slidably connected to sliding rods 94, and the sliding rods 94 are located in the inner cavities of the sliding grooves 93 opened on the two rings 92;

[0047] Next, a fixing plate 95 is fixed to the side of the outer surface of five of the slide bars 94 away from the output motor 90, and an L-shaped plate 96 is fixed to the side of the outer surface of another slide bar 94 away from the output motor 90. The L-shaped plate 96 and the matching component 5 are in the same straight line. A winding roller 98 is fixed to the side of the end of the five fixing plates 95 close to the output motor 90 and away from the connecting rod 91, and a slide rail is fixed to the end of the L-shaped plate 96 close to the matching component 5;

[0048] Among them, two symmetrical automatic clamps 97 are provided at one end of the slide rail close to the matching component 5. The two automatic clamps 97 slide on the slide rail and can be locked according to the width of the leather. In addition, the automatic clamps 97 and the matching component 5 are in the same straight line, which is convenient for the automatic clamps 97 to clamp the two sides of the leather. The automatic clamps 97 drive the fixed plate connected to the sliding side on one side through the electric cylinder, so that the groove on the fixed plate forms a limit for the rotating rod, so that the upper clamping roller is separated from the lower clamping roller, and then the leather contacts the lower clamping roller, and the upper clamping roller rotates back in the opposite direction to clamp the leather;

[0049] In addition, the outer surfaces of the five winding rollers 98 and the automatic clamp 97 are all on the same circle drawn with the center of the ring 92 as the center. The diameter of the circle is the winding diameter, so that the leather can be wound around the outer surfaces of the five winding rollers 98 in sequence after being clamped by the automatic clamp 97, avoiding the leather from tilting during the winding process.

[0050] Further, if Figure 6 and Figure 7 As shown, a motor 921 is fixed at the center of the rear end of the circular ring 92 away from the output motor 90, and a circular plate 922 is fixed at the output end of the motor 921. Six limiting grooves 923 cooperating with the slide bars 94 are provided on the outer surface of the circular plate 922. When the circular plate 922 rotates, under the action of the limiting grooves 923, the six slide bars 94 move toward the center of the circular ring 92 along the corresponding slide grooves 93, thereby shortening the distance between the five winding rollers 98 and the automatic clamp 97 and the center of the circular ring 92, shortening the winding diameter, and thus adapting to leathers of different materials, avoiding excessive winding diameter, destroying the tension in the leather, and causing the leather to deform and damage;

[0051] Among them, a support assembly 924 adapted to the six slide bars 94 is fixed to the front end of the circular ring 92 away from the output motor 90. The support assembly 924 includes a fixing ring and six supporting springs. The fixing ring is sleeved on the outer surface of the connecting rod 91. The six supporting springs respectively support the corresponding slide bars 94 to prevent the slide bars 94 from shrinking.

[0052] During the winding process, two automatic clamps 97 clamp the leather so that the leather is wound around the outer surfaces of multiple winding rollers 98 in sequence. At the same time, the embossing roller 34 and the supporting roller 44 exert a certain pressure on the leather during the embossing process, and the two rotating automatic clamps 97 exert a certain pulling force on the leather, so that the leather remains flat during this process and wrinkles on the wound leather are avoided.

[0053] Further, if Fig. 9As shown, the unloading component 7 includes five matching plates 70 and four limit blocks 72. The five matching plates 70 are slidably connected to the outer surfaces of the five slide bars 94 corresponding to the winding rollers 98. The four limit blocks 72 are fixed to the outer surface of the ring 92 close to the output motor 90 and are respectively located between two adjacent matching plates 70. The rear ends of the four limit blocks 72 are all fixed with limit rods 73. The outer surfaces of the four limit rods 73 are all provided with two rotatably connected telescopic plates 71, and the telescopic plates 71 slide on the outer surfaces of the limit rods 73.

[0054] Among them, the two telescopic plates 71 located on the outer surface of the same limit rod 73 are rotatably connected to the two adjacent matching plates 70 at one end away from the limit rod 73, so that when the matching plate 70 moves toward the center of the circular ring 92, the five matching plates 70 can move synchronously through the mutual connection of the telescopic plates 71. The ends of the five matching plates 70 away from the center of the circular ring 92 are fixed with pushing ring blocks 74 adapted to the winding roller 98. The inner cavity of the pushing ring block 74 is in close contact with the outer surface of the winding roller 98, and the pushing ring block 74 can slide on the outer surface of the winding roller 98 to facilitate pushing the rolled leather.

[0055] Further, if Fig.10 As shown, the moving assembly 8 includes a driving rail 80, which is fixed to the rear end of the mounting plate 6. A lifter 81 is provided on the upper side of the driving rail 80. The lifter 81 is slidably connected to the driving rail 80. A clamping plate 82 adapted to the pushing ring block 74 is fixed to the front end of the lifter 81. The clamping plate 82 is composed of two parallel straight plates. The distance between the two straight plates is used to place the pushing ring block 74. The clamping plate 82 is used to push two adjacent pushing ring blocks 74, so that the five pushing ring blocks 74 move synchronously, and the rolled leather can be disassembled.

[0056] It should be noted that the embossing roller 34, lifting cylinder 40, support roller 44, telescopic plate 71, moving assembly 8 and automatic clamp 97 in the present invention are all prior arts, and their installation and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0057] Specific implementation of the device: The device is a leather production equipment, mainly used for embossing leather and rolling up the embossed leather;

[0058] Specifically, during the use of the device, the distance between the embossing roller 34 and the supporting roller 44 is first adjusted according to the thickness of the leather to adapt the leather for use, and the lifting cylinder 40 is used to move the U-shaped block 41 up and down to make the distance between the embossing roller 34 and the supporting roller 44 adapt to the rear end of the leather;

[0059] Next, the leather is fed from the upper side of the feeding block 43 into the space between the embossing roller 34 and the supporting roller 44 for embossing. The embossed leather moves out from the left side. The two limiting components 46 limit the movement direction of the leather so that the leather moves along the inclined groove on the upper side of the discharging block 2. Then, the temperature of the leather is lowered by the cooling component to avoid deformation of the leather caused by pulling during winding. Then, the leather moves to the upper side of the matching component 5.

[0060] When the leather moves to the upper side of the matching component 5, the cylinder moves with the mounting plate 6, so that the two automatic clamps 97 approach the matching component 5, and then clamp the edge of the leather. Then, the connecting rod 91 at the output end of the output motor 90 rotates with the two rings 92, so that the five winding rollers 98 rotate clockwise to sequentially wrap the leather around the surface of the winding rollers 98, and the leather is rolled up.

[0061] During the leather rolling process, the two automatic grippers 97 grip the leather so that the leather is wound around the outer surfaces of the multiple winding rollers 98 in sequence. At the same time, the embossing roller 34 and the supporting roller 44 exert a certain pressure on the leather during the embossing process, and the two rotating automatic grippers 97 exert a certain pulling force on the leather, so that the leather remains flat during this process, avoiding wrinkles on the rolled leather.

[0062] In addition, if Figure 8 As shown, when rolling up the leather, the diameter of the rolling up needs to be adjusted according to the material of the leather, wherein the rolling up diameter is the distance between the outer surface edge of the five rolling rollers 98 and an automatic clamp 97 and the center of the ring 92, so that the internal tension of the leather will not be destroyed during the rolling up process, and the leather can be prevented from being deformed and damaged. The motor 921 controls the rotation of the circular plate 922, and under the action of the limit groove 923, the six slide bars 94 move along the corresponding slide groove 93 toward the center of the ring 92, so that the distance between the outer surface of the five rolling rollers 98 and an automatic clamp 97 and the center of the ring 92 is changed, so as to achieve the purpose of changing the rolling up diameter and improve the applicability of the device;

[0063] Then, if Fig.10As shown, after the winding is completed, the rolled leather needs to be automatically unloaded, and the lifter 81 is adjusted to contact the surface of the rolled leather to support the rolled leather. Then, the motor 921 controls the circular plate 922 to rotate. Under the action of the limit groove 923, the six slide bars 94 are all moved to the side of the center of the circular ring 92, and the two automatic clamps 97 release the clamped leather edges. At this time, the winding roller 98 and the automatic clamp 97 are all moved to the side of the center of the circular ring 92, so that the winding roller 98 is no longer in contact with the leather. The rolled leather is supported by the lifter 81, and then the driving slide rail 80 moves with the lifter 81, and the clamping plate 82 moves with the two adjacent push ring blocks 74. Through the action of the telescopic plate 71, the five matching plates 70 move at the same time, so the five push ring blocks 74 move on the outer surfaces of the five winding rollers 98 at the same time, and the rolled leather is pushed down from the outer surfaces of multiple winding rollers 98, so as to achieve the purpose of automatic unloading.

[0067] S2. Clamping and rolling leather: The two automatic clamps 97 move toward one side of the matching component 5 to clamp the embossed leather, and then move to the side away from the matching component 5 to facilitate rolling. Before rolling, the distance between the automatic clamps 97 and the multiple winding rollers 98 and the center of the ring 92 can be adjusted through the action of the circular plate 922 and the limiting groove 923, so that the rolling diameter is adapted to the material of the leather;

[0068] S3, automatic unloading: The rolled leather can be supported by the provided lifter 81, and the limit groove 923 is used to make the automatic clamper 97 and the plurality of winding rollers 98 retract inward, so that the rolled leather falls on the upper side of the lifter 81, and then the clamping plate 82 is used to move the five pushing ring blocks 74 to push the rolled leather off the surface of the winding roller 98, so as to achieve the purpose of automatic unloading.
