[0003] In order to facilitate the packaging and transportation of leather, the processed leather is wound into a cylinder by winding. The leather is more flexible and stronger than cloth, and is prone to wrinkles during the conveying process. The winding in this state will affect the overall quality of the leather. SUMMARY

[0004] The present application discloses a guiding type winding equipment for leather processing and a method thereof, which aims to solve the technical problem of wrinkles occurring during the conveying process in the background art, which affects the overall quality of the leather.

[0005] The guiding type winding equipment for leather processing comprises a middle table, a front roller and a rear roller are arranged on the middle table, two symmetrical chassis are fixedly connected to the lower side of the middle table, a feeding roller is arranged between the two chassis, a few character brackets are arranged on one side of each of the two chassis, the two few character brackets are fixedly connected between the middle table, L-shaped support frames are arranged at the lower ends of the two few character brackets, an output roller is arranged between the two L-shaped support frames, a movable position roller is arranged between the L-shaped support frames and the few character brackets, the movable position roller is located below the rear roller, the outer side of the rear roller is provided with a knocking type wrinkle removing assembly, and a movable position material pulling assembly is arranged on the movable position roller.

[0006] The middle table, the front roller, the rear roller, the chassis, the feeding roller, the few character brackets, the L-shaped support frames, the output roller, the movable position roller, the roller shaft, the roller, the knocking type wrinkle removing assembly and the movable position material pulling assembly are arranged, the surface of the leather is continuously knocked by the knocking type wrinkle removing assembly during the conveying process of the winding leather, the movable position material pulling assembly continuously assists the pulling at the same time, the relaxed state of the leather is changed, the leather is in a high-frequency breaking and pulling operation state during the conveying of the rear roller, the movable position roller and the output roller, the wrinkles on the surface of the leather are effectively removed, and the quality of the leather is improved.

[0007] In a preferred embodiment, the tapping wrinkle removal component includes a front mounting plate, with side seats fixedly connected to both sides of the front mounting plate. Both side seats are fixedly connected to a central platform, and the two side seats are symmetrically distributed on both sides of the front mounting plate. Each side seat has a circular hole, and a rotating rod is movably connected inside each hole. A driving gear is fixedly connected to the upper end of each rotating rod, located above the side seat. Three equidistant rotating rings are fixedly connected to each rotating rod, and three circumferentially equidistant tri-lobed rods are fixedly connected to the outside of each rotating ring. Each tri-lobed rod has a mounting groove at its front end, and a tapping rod is movably connected inside each mounting groove. A rubber rod is provided at the front end of each tapping rod, and a rubber rod is fixed to the tapping rod. The front mounting plate is connected to a sleeve, and a return spring is fixedly connected to each sleeve. The other end of the return spring is fixedly connected to the three-leaf rod where the sleeve is located. Two symmetrical upper seats are fixedly connected to the upper side of the front mounting plate. Both upper seats have round holes. The same shaft is movably connected between the round holes of the two upper seats. Both ends of the shaft are fixedly connected to linkage gears. The two linkage gears mesh with the two driving gears through tooth grooves. A secondary driving gear is fixedly connected to the outside of the shaft. A drive motor is fixedly connected to the upper side of the front mounting plate. The output end of the drive motor is connected to a short shaft through a coupling. The other end of the short shaft is fixedly connected to a drive gear. The drive gear and the secondary driving gear mesh with each other through tooth grooves.

[0008] The system incorporates a tapping wrinkle-removing component. This component uses multiple rotating rubber rods to continuously tap the leather at both ends, altering its surface condition. The leather deforms during tapping, effectively removing wrinkles and ensuring its quality. The flip-type tapping rod utilizes the elasticity of a return spring to reduce direct contact with the leather, preventing damage. The rubber rods also undergo elastic deformation under pressure, further protecting the leather.

[0009] In a preferred embodiment, the movable material pulling assembly includes two rail frames symmetrically distributed at both ends of the movable roller. The two rail frames are fixedly connected to a Z-shaped connecting frame and an L-shaped support frame on the same side, respectively. Each rail frame has a sliding groove. Slide seats are fixedly connected to both ends of the roller shaft on the movable roller. The two slide seats are movably connected within the sliding grooves of the two rail frames. Mounting rods are fixedly connected to the side of each slide seat away from the rail frame. The front end of each mounting rod has a threaded groove, and a weight plate is sleeved on the outside of each mounting rod. A locking knob is provided on the side away from the slide table. The locking knob is rotatably connected to the mounting rod through the inner wall thread. A base is fixedly connected to the bottom of each of the two rail frames. Two symmetrical circular holes are opened on each base. A slide rod is movably connected inside each of the two circular holes. The upper end of the two slide rods is fixedly connected to the same pad. The pad is located directly below the movable roller. A layer is fixedly connected to each of the two slide rods. A buffer spring is sleeved on the outside of each of the two slide rods. The upper and lower ends of the buffer spring are fixedly connected to the lower side of the layer and the upper side of the base, respectively.

[0010] By incorporating a movable material pulling assembly, which uses a weighted disc to alter the weight of the movable roller, the leather remains taut during transport between the rear roller, movable roller, and discharge roller, ensuring the tightness of the leather during winding. Simultaneously, during the knocking and wrinkle removal process, the movable roller changes position according to the leather's deformation. During the knocking intervals, gravity provides a downward pull on the leather, keeping it in a continuous state of relaxation and tension, effectively altering the leather's surface shape and eliminating wrinkles. If the leather transport is interrupted and the movable roller drops significantly, a buffer spring cushions the overall potential energy of the descending movable roller and platform, preventing the movable roller from detaching or impacting the platform.

[0011] In a preferred embodiment, gantry frames are fixedly connected to both sides of the central platform, the two gantry frames are symmetrically distributed, the upper ends of the two gantry frames are fixedly connected to the same top seat, and a pressure-shifting smoothing component is provided on the central platform.

[0012] In a preferred embodiment, the pressure-shifting smoothing assembly includes a pressure plate and a support platform. The pressure plate is located directly below the top seat. The top seat has two rectangular mounting holes, and a downward-pressing hydraulic cylinder is fixedly connected inside each of the two rectangular mounting holes. The telescopic ends of the two downward-pressing hydraulic cylinders are fixedly connected to the upper side of the pressure plate. The support platform is located above the central platform, and a rectangular mounting groove is provided on the central platform. A lifting hydraulic cylinder is fixedly connected inside the rectangular mounting groove, and the upper end of the lifting hydraulic cylinder is fixedly connected to the lower side of the support platform. The cross-section of the support platform is elliptical. Two symmetrical pressure frames are fixedly connected to the lower side of the pressure plate, and two... Each of the two pressure frames has a symmetrical rotating shaft, with a wheel fixedly connected to one end. A belt is installed between two wheels on the same side. A synchronous motor is fixedly connected to the opposite side of each wheel on both pressure frames. The output end of each synchronous motor is connected to a short shaft via a coupling. The other end of the short shaft is fixedly connected to a rotating shaft. Each rotating shaft has multiple equidistant conveyor wheels, and a conveyor belt is installed between the conveyor wheels on the two rotating shafts of the same pressure frame. Multiple equidistant grooves are opened on the outer side of each conveyor belt. A functional spring is fixedly connected inside each groove. The other end of each functional spring is fixedly connected to a smoothing seat, and a spherical roller is installed on each smoothing seat.

[0013] By incorporating a shifting pressure smoothing component, the component uses an elliptical cross-section support to lift the leather from below, causing the leather to conform to the support and form an arc. During transport, spherical rollers on a continuously moving smoothing seat continuously roll over the surface of the leather, stretching it to both sides while it is being transported normally. This helps the leather unfold and conform to the support, achieving the effect of smoothing the leather and removing wrinkles.

[0014] A guide-type winding method for leather processing, using a guide-type winding device for leather processing as described above, includes the following steps:

[0015] Step 1: Place the leather (the equipment is installed in front of the take-up drum). The leather is fed in by the feed roller, passes over the front roller, passes over the movable roller from the rear roller, and finally passes out from the discharge roller and is wound back on the take-up drum.

[0016] Step 2: As the leather is conveyed between the front and rear rollers, the shifting pressure smoothing assembly assists in flattening the moving leather.

[0017] Step 3: When the leather is conveyed between the rear roller, the movable roller and the discharge roller, the knocking wrinkle removal component knocks the leather to remove wrinkles. During the process, the movable pulling component provides auxiliary pulling for the leather.

[0018] As can be seen from the above, the guide-type winding equipment for leather processing provided by the present invention uses a knocking wrinkle removal component to continuously knock on the surface of the leather, while the live-position pulling component continuously assists in pulling. The relaxed state of the leather is changed, and the leather is in a high-frequency snapping and pulling state during the conveying of the rear roller, the live-position roller and the discharge roller, which effectively removes wrinkles on the surface of the leather and improves the quality of the leather.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] The present invention discloses a guide-type winding device for leather processing, which is mainly used in scenarios where wrinkles occur during the conveying process and the winding will affect the overall quality of the leather.

[0031] Reference Figures 1-8A guide-type winding device for leather processing includes a central platform 1, on which a front roller 2 and a rear roller 3 are mounted. Two symmetrical base frames 4 are bolted to the lower side of the central platform 1. A feed roller 5 is positioned between the two base frames 4. A Z-shaped bracket 6 is mounted on one side of each base frame 4. Both Z-shaped brackets 6 are bolted to the central platform 1, and each Z-shaped bracket 6 has an L-shaped support 7 at its lower end. A discharge roller 8 is provided between the L-shaped support frame 7 and the Z-shaped connecting frame 6. A movable roller 9 is provided between the L-shaped support frame 7 and the Z-shaped connecting frame 6. The movable roller 9 is located below the rear roller 3. The front roller 2, rear roller 3, feed roller 5, discharge roller 8 and movable roller 9 all include roller shaft 10 and roller cylinder 11. The roller shaft 10 and roller cylinder 11 are rotatably connected by bearings. A knocking wrinkle removal component 12 is provided on the outside of the rear roller 3. A movable material pulling component 13 is provided on the movable roller 9.

[0032] Specifically, the device is installed in front of the take-up drum. The leather to be wound enters through the feed roller 5, passes upward over the front roller 2, passes downward over the movable roller 9 from the rear roller 3, and finally exits from the discharge roller 8 to be wound back on the take-up drum. When the leather is conveyed between the rear roller 3, the movable roller 9, and the discharge roller 8, the knocking wrinkle removal component 12 knocks and removes wrinkles from the leather. During this process, the movable pulling component 13 provides auxiliary pulling for the leather. During the conveying of the wound leather, the device uses the knocking wrinkle removal component 12 to continuously knock on the surface of the leather, while the movable pulling component 13 continuously provides auxiliary pulling. The relaxed state of the leather is changed, and the leather is in a high-frequency snapping and pulling state during the conveying of the rear roller 3, the movable roller 9, and the discharge roller 8, which effectively removes wrinkles from the surface of the leather and improves the quality of the leather.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The tapping wrinkle removal component 12 includes a front mounting plate 1201. Side seats 1202 are bolted to both sides of the front mounting plate 1201. Both side seats 1202 are bolted to the central platform 1, and the two side seats 1202 are symmetrically distributed on both sides of the front mounting plate 1201. Each side seat 1202 has a circular hole, and a rotating rod 1203 is rotatably connected to the inside of each hole via a bearing. The upper end of each rotating rod 1203 is bolted to a driving gear 1210. Wheel 1210 is located above side seat 1202, and three equidistant rotating rings 1204 are bolted to each of the two rotating rods 1203. Three circumferentially equidistant tri-lobe rods 1205 are bolted to the outside of each rotating ring 1204. Each tri-lobe rod 1205 has a mounting groove at its front end, and a striking rod 1206 is rotatably connected to the inside of each mounting groove via a bearing. A rubber rod 1207 is provided at the front end of each striking rod 1206, and a sleeve 12 is bolted to each striking rod 1206. 08. Each sleeve 1208 is bolted with a return spring 1209. The other end of the return spring 1209 is bolted to the three-leaf rod 1205 where the sleeve 1208 is located. Two symmetrical upper seats 1211 are bolted to the upper side of the front mounting plate 1201. Each upper seat 1211 has a round hole, and the round holes of the two upper seats 1211 are rotatably connected by a bearing to the same shaft 1212. Both ends of the shaft 1212 are bolted together. The driving gear 1213 and the two linkage gears 1213 respectively mesh with the two driving gears 1210 through tooth grooves. The secondary driving gear 1214 is bolted to the outside of the shaft 1212. The drive motor 1215 is bolted to the upper side of the front plate 1201. The output end of the drive motor 1215 is connected to a short shaft through a coupling. The other end of the short shaft is bolted to the driving gear 1216. The driving gear 1216 and the secondary driving gear 1214 mesh with each other through tooth grooves.

[0034] Specifically, the drive motor 1215 drives the active gear 1216 to mesh with the secondary gear 1214, the shaft 1212 rotates to drive the two linkage gears 1213 to mesh with the traction gear 1210, the rotating rod 1203 rotates to drive the rotating ring 1204 to rotate, and the rubber rod 1207 at the front end of the three-leaf rod 1205 continuously strikes the surface of the leather. During the striking process, when the rubber rod 1207 comes into contact with the leather, the rubber plate itself will deform, and at the same time the striking rod 1206 will deflect as a whole. The return spring 1209 is compressed and undergoes elastic deformation. Under the continuous drive of the drive motor 1215, the rubber rod 1207 continuously strikes the surface of the leather.

[0035] In specific application scenarios, the tapping wrinkle removal component 12 is suitable for the tapping wrinkle removal process when leather is conveyed between the rear roller 3 and the movable roller 9. That is, the tapping wrinkle removal component 12 uses multiple rotating rubber rods 1207 to continuously tap the two ends of the leather, changing the surface state of the leather. When tapped, the leather will deform, which can effectively remove wrinkles on the surface of the leather and ensure the quality of the leather. The flipping tapping rod 1206 uses the elasticity of the return spring 1209 to reduce the direct contact force with the leather and avoid damage to the leather. The rubber rod 1207 will undergo elastic deformation after being compressed, further achieving the purpose of protecting the leather.

[0036] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The movable material pulling assembly 13 includes two rail frames 1301, which are symmetrically distributed at both ends of the movable roller 9. The two rail frames 1301 are bolted to the Z-shaped bracket 6 and L-shaped support 7 on the same side, respectively. Each rail frame 1301 has a sliding groove. Both ends of the roller shaft 10 on the movable roller 9 are bolted to sliding bases 1302. The two sliding bases 1302 are slidably connected within the sliding grooves of the two rail frames 1301. On the side of each sliding base 1302 away from the rail frame 1301, a mounting rod 1303 is bolted to it. The front end of each mounting rod 1303 has a threaded groove. A weight plate 1304 is sleeved on the outside of each mounting rod 1303. The weight plate 1304 has a threaded groove on its side away from the sliding base 1302. Each side is equipped with a locking knob 1305, which is rotatably connected to the mounting rod 1303 via an inner wall thread. The bottom of each of the two rail frames 1301 is bolted to a base 1306. Each base 1306 has two symmetrical circular holes, and a slide rod 1307 is slidably connected inside each of the two circular holes. The upper ends of the two slide rods 1307 are bolted to the same pad 1308, which is located directly below the movable roller 9. Each of the two slide rods 1307 is bolted to a layer 1309, and a buffer spring 1310 is sleeved on the outside of each of the two slide rods 1307. The upper and lower ends of the buffer spring 1310 are bolted to the lower side of the layer 1309 and the upper side of the base 1306, respectively.

[0037] Specifically, the movable roller 9 is suspended during the leather conveying process, and the suspension height can be changed by adjusting the weight of the weight plate 1304. When the tapping wrinkle removal component 12 is running, the leather will deform when it is tapped by the rubber rod 1207. The movable roller 9 is lifted upward by the upward lifting force. During the intervals of the alternating tapping of the rubber rod 1207, the leather will be stretched straight by the downward pulling force under the action of the movable roller 9 and the weight plate 1304. This process is repeated, and the leather is in a continuous state of relaxation and tension.

[0038] In specific application scenarios, the movable material pulling assembly 13 is suitable for the auxiliary stage during leather knocking and wrinkle removal. That is, the movable material pulling assembly 13 uses the weight plate 1304 to change the weight of the movable roller 9, so that the leather is in a taut state during the conveying of the rear roller 3, the movable roller 9 and the discharge roller 8, ensuring the tightness of the leather when it is rolled. At the same time, during the knocking and wrinkle removal, the movable roller 9 can change its position according to the deformation of the leather. During the knocking interval, gravity provides a downward pulling force to the leather, so that the leather is in a continuous state of relaxation and tension, effectively changing the surface shape of the leather and eliminating the wrinkles. When the leather conveying is interrupted and the movable roller 9 falls sharply, the buffer spring 1310 will buffer the overall potential energy of the movable roller 9 and the pad 1308 falling, preventing the movable roller 9 from falling off and impacting.

[0039] Reference Figure 1 , Figure 2 and Figure 7 Both sides of the central platform 1 are bolted to a gantry frame 14. The two gantry frames 14 are symmetrically distributed. The upper ends of the two gantry frames 14 are bolted to the same top seat 15. The central platform 1 is equipped with a pressure-shifting smoothing component 16.

[0040] Reference Figure 7 , Figure 8 and Figure 9The pressure-shifting smoothing assembly 16 includes a pressure plate 1601 and a support platform 1602. The pressure plate 1601 is located directly below the top seat 15. The top seat 15 has two rectangular mounting holes, and each of the two rectangular mounting holes is bolted to a downward hydraulic cylinder 1603. The telescopic ends of the two downward hydraulic cylinders 1603 are bolted to the upper side of the pressure plate 1601. The support platform 1602 is located above the central platform 1. The central platform 1 has a rectangular mounting groove, and a lifting hydraulic cylinder 1604 is bolted to the inside of the rectangular mounting groove. The upper end of the lifting hydraulic cylinder 1604 is bolted to the lower side of the support platform 1602. The cross-section of the support platform 1602 is elliptical. The lower side of the pressure plate 1601 is bolted to two symmetrical pressure frames 1605. Each of the two pressure frames 1605 is rotatably connected to two symmetrical rotating shafts 1606 via bearings. One end of each pressure frame 1605 is bolted to a wheel 1607. A belt 1608 is installed between two wheel 1607s on the same side. A synchronous motor 1609 is bolted to the opposite side of each pressure frame 1605. The output end of each synchronous motor 1609 is connected to a short shaft via a coupling. The other end of the short shaft is bolted to a rotating shaft 1606. Multiple equidistant conveyor wheels 1610 are installed on each rotating shaft 1606. A conveyor belt 1611 is installed between the conveyor wheels 1610 on the two rotating shafts 1606 of the same pressure frame 1605. Multiple equidistant grooves are opened on the outer side of each conveyor belt 1611. Functional springs 1612 are bolted to the inside of each groove. The other end of each functional spring 1612 is bolted to a smoothing seat 1613. Spherical rollers 1614 are installed on each smoothing seat 1613.

[0041] Specifically, initially, the top of the support platform 1602 is at the same height as the front roller 2 and the rear roller 3. After the leather is installed, the lifting hydraulic cylinder 1604 is adjusted to lift the leather by the support platform 1602. Then, the pressing hydraulic cylinder 1603 is adjusted to move the pressure plate 1601 down until the spherical roller 1614 on the smoothing seat 1613 contacts and squeezes the leather surface, and the functional spring 1612 undergoes elastic deformation. When the component is in operation: the two synchronous motors 1609 rotate synchronously, the conveyor belts 1611 on the two pressure frames 1605 rotate synchronously in opposite directions, and the spherical roller 1614 on the smoothing seat 1613 moves from high to low on the support platform 1602, smoothing the surface of the leather during the movement.

[0042] In specific application scenarios, the shifting pressure smoothing component 16 is suitable for smoothing leather during the process of the front roller 2 and the rear tube. The shifting pressure smoothing component uses an elliptical cross-section support 1602 to lift the leather from below, so that the leather adheres to the support 1602 and forms an arc. Then, during the conveying process, the spherical rollers 1614 on the continuously moving smoothing seat 1613 continuously roll on the surface of the leather. While the leather is being conveyed normally, it is stretched to both sides, which helps the leather to unfold and adhere to the support 1602, thereby smoothing the leather and removing wrinkles.

[0043] A guide-type winding method for leather processing, using a guide-type winding device for leather processing as described above, includes the following steps:

[0044] Step 1: Place the leather (the equipment is installed in front of the take-up drum). The leather is fed in by the feed roller 5, passes over the front roller 2, passes over the movable roller 9 from the rear roller 3, and finally passes out from the discharge roller 8 and is wound back on the take-up drum.

[0045] Step 2: When the leather is conveyed between the front roller 2 and the rear roller 3, the shifting pressure smoothing assembly 16 assists in flattening the moving leather (two synchronous motors 1609 rotate synchronously, the conveyor belts 1611 located on the two pressure frames 1605 rotate synchronously in opposite directions, and the spherical rollers 1614 on the smoothing seat 1613 move from high to low on the support platform 1602, smoothing the surface of the leather during the movement).

[0046] Step 3: When the leather is conveyed between the rear roller 3, the movable roller 9, and the discharge roller 8, the knocking wrinkle removal assembly 12 knocks and removes wrinkles from the leather (the drive motor 1215 drives the drive gear 1216 to mesh with the secondary gear 1214, the shaft 1212 rotates and drives the two linkage gears 1213 to mesh with the traction gear 1210, the rotating rod 1203 rotates and drives the rotating ring 1204 to rotate, and the rubber rod 1207 at the front end of the three-leaf rod 1205 continuously knocks on the surface of the leather. During the knocking process, when the rubber rod 1207 comes into contact with the leather, the rubber plate itself will deform, and at the same time the knocking rod...). 1206 deflects as a whole, the return spring 1209 is compressed and undergoes elastic deformation, and under the continuous drive of the drive motor 1215, the rubber rod 1207 continuously strikes the surface of the leather. During this process, the movable pulling assembly 13 assists in pulling the leather (the leather will deform when struck by the rubber rod 1207, the movable roller 9 will move upward due to the upward lifting force, and during the intervals of the alternating strikes of the rubber rod 1207, the leather will be stretched straight by the downward pulling force due to the tension of the movable roller 9 and the weight plate 1304. This process is repeated, and the leather is in a continuous state of relaxation and tension).

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
