Technical Field
[0001] The invention belongs to the technical field of sofa leather production, in particular to a winding device for producing microfiber suede sofa leather. Background Art
[0002] Microfiber suede sofa leather is a synthetic leather made of microfiber as the base fabric and a layer of PU coating on the surface. This material combines the texture of natural leather and the advantages of synthetic materials, and has similar appearance and performance to natural leather. In the production process of sofa leather, in order to facilitate the transportation process of sofa leather, a winding device is usually used to effectively wind up the sofa leather for easy storage and transportation.
[0003] The conventional winding device for sofa leather is mainly composed of a frame and a winding roller. When in use, the winding roller is driven by a motor to rotate to realize the winding process of the sofa leather. However, in actual use, that is, after the winding roller is wound, it is usually necessary to remove the winding roller from the frame, and after disassembly, the transmission structure needs to be separated. The whole process is extremely complicated and the transmission roller cannot be quickly separated.
[0004] At the same time, during the winding process of the sofa leather, if the winding is stopped before it is completed, the winding force applied to the winding roller will disappear. At the same time, the surface of the winding roller lacks a certain limiting device, which leads to the risk of the sofa leather on the surface of the winding roller loosening, which will affect the winding quality and urgently needs to be improved. Summary of the invention
[0005] The purpose of the present invention is to provide a winding device for producing microfiber suede sofa leather to solve the problems raised in the above background technology.
[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: A winding device for producing microfiber suede sofa leather, comprising a base, a support assembly is movably installed on the top of the base, a base is fixedly installed on the top of the support assembly, a winding roller is movably installed in the middle of the base, and slots are provided at positions near the upper and lower ends on the left and right sides of the base, and the inside of the slots are movably connected with limit clamps located on the outer side of the winding roller, and the limit assemblies are fixedly installed on the left and right sides of the base, and the upper and lower ends of the limit assembly are movably connected with the two limit clamps, a power assembly located on one side of the winding roller is fixedly installed on one side of the base, and a flattening assembly located on the front of the winding roller is fixedly installed on one side of the base, and the left and right ends of the winding roller are provided with limit slots, and the inside of the limit slots are movably sleeved with a transmission shaft, the winding roller is movably connected to the base through the transmission shaft, and the transmission shaft located on one side is transmission-connected to the power assembly, and a reset spring is fixedly connected between the transmission shaft and the limit slot, and when the reset spring is in the limit compression state, the transmission shaft is completely located inside the limit slot.
[0007] Before winding the sofa leather, the free end of the sofa leather needs to be fixedly connected to the outer side of the winding roller, and the free end needs to pass through the middle of the flattening component, and ensure that the winding roller can drive the sofa leather to rotate to complete the preparation work before winding the sofa leather.
[0008] When it is necessary to separate the winding roller and the machine base, the left and right transmission shafts can be pressed inward at the same time. At this time, the return spring located inside the limit groove is compressed and drives the two transmission shafts to move toward the inside of the limit groove. When it is fully retracted into the inside of the limit groove, the connection between the winding roller and the machine base is released, and the winding roller can be removed. Otherwise, the assembly between the winding roller and the machine base can be completed.
[0009] As a further technical solution of the present invention, the support assembly includes two left and right guide blocks, a guide groove is provided at the top of the base and the guide block is movably engaged with the inside of the guide groove, and an electric push rod located inside the guide groove is fixedly installed between the two guide blocks.
[0010] As a further technical solution of the present invention, the top end of the guide block is fixedly connected to a first fixed seat, the end of the first fixed seat away from the guide block is movably connected to a first connecting rod via a rotating shaft, the end of the first connecting rod away from the first fixed seat is movably connected to a second fixed seat via a rotating shaft, and the top end of the second fixed seat is connected to the bottom end of the machine base.
[0011] When it is necessary to wind the sofa leather, the electric push rod can be turned on and its extension can be controlled. When the electric push rod is extended, the two guide blocks can be pushed relatively away. At this time, the distance between the two guide blocks increases accordingly, and the two first connecting rods are deflected toward the middle and exert a downward pulling force on the second fixed seat until the machine base is driven to move downward. When the electric push rod is stretched to the limit state, that is, the distance between the two guide blocks is at the maximum value, the machine base can be at the lowest point.
[0012] As a further technical solution of the present invention, the power assembly includes an L-shaped frame, a limit seat is fixedly installed on the top of the L-shaped frame, a limit block is movably engaged inside the limit seat, and one end of the limit block away from the winding roller is fixedly connected to a second limit spring located inside the limit seat, and the other end of the second limit spring is connected to one side of the inner cavity of the limit seat.
[0013] As a further technical solution of the present invention, one end of the limit block away from the second limit spring passes through one side of the limit seat and is fixedly connected to a motor, a transmission sleeve is fixedly installed on the output end of the motor, and an electromagnet is fixedly installed on the side of the transmission sleeve close to the winding roller. When the winding roller is at the highest point, the transmission sleeve and the transmission shaft are movably connected.
[0014] When the machine base drops to the lowest point, the winding roller also drops to the lowest point, and the winding roller corresponds to the power component. At this time, the electromagnet on one side of the transmission sleeve can be turned on, and the transmission sleeve moves toward the direction of the transmission shaft, and adsorbs on one side of the transmission shaft, and drives the transmission sleeve and the transmission shaft to be actively connected. At this time, the second limit spring can be stretched, and drives the limit block and the motor as a whole to move toward the direction close to the winding roller. At this time, the motor can be turned on to drive the winding roller to rotate through the transmission sleeve and the transmission shaft to complete the winding process of the sofa leather; When it is necessary to disassemble the winding roller, the electromagnet of the transmission sleeve can be turned off, which can drive the motor and the transmission sleeve to automatically reset. At this time, the sleeve connection between the transmission sleeve and the transmission shaft can be released. At the same time, the support assembly can be controlled to automatically reset to drive the machine base and the winding roller to rise, completing the disassembly process.
[0015] By utilizing the coordination between the support assembly and the power assembly, the device only needs to control the support assembly to drive the machine base to descend, and cooperate with the power assembly to quickly complete the power transmission process. At the same time, the power transmission can also be quickly released during disassembly. The entire process is completed quickly without the need for a complicated disassembly process, and the winding roller can be quickly separated, thereby improving the winding efficiency.
[0016] As a further technical solution of the present invention, the limiting assembly includes a fixed tube, the outer side surface of the fixed tube is connected to the machine base through a locking frame, the interior of the fixed tube is movably sleeved with a movable plate, the end of the movable plate away from the machine base is fixedly connected to a movable rod located inside the fixed tube, and the end of the movable rod away from the movable plate passes through one end of the fixed tube and is fixedly connected to a movable seat.
[0017] As a further technical solution of the present invention, the outer side surface of the movable rod is movably sleeved with a first limit spring, the two ends of the first limit spring are respectively connected to one end of the movable plate and one end of the inner cavity of the fixed tube, and the upper and lower ends of the movable seat close to the machine base are fixedly installed with a third fixed seat.
[0018] As a further technical solution of the present invention, one end of the third fixed seat away from the movable seat is movably connected to the second connecting rod via a rotating shaft, one end of the second connecting rod away from the third fixed seat is movably connected to the fourth fixed seat via a rotating shaft, and one end of the fourth fixed seat away from the second connecting rod is connected to one side of the limiting clamp.
[0019] When winding, that is, the first limit spring is in the initial state, the distance between the movable seat and the fixed tube is the maximum value, and the inner side of the limit splint is in contact with the outer side of the sofa leather. At the same time, the distance between the upper and lower fourth fixed seats is also the minimum value. As the winding progresses, the thickness of the sofa leather located on the outer side of the winding roller increases. At this time, the upper and lower limit splints move away from each other and drive the two fourth fixed seats away from each other. Under the guidance of the second connecting rod, the movable seat can be driven to move toward the fixed tube, and the first limit spring is stretched. At the same time, under the elastic force of the first limit spring, the limit splint is always driven to contact with the outer side of the sofa leather to maintain the limiting process of the sofa leather.
[0020] By utilizing the cooperation between the winding roller, the limiting clamp and the limiting assembly, through the elastic force of the first limiting spring, and the limiting process of the sofa leather by the limiting clamp, it is ensured that during the winding process, the outer side surface of the sofa leather can always be in contact with the inner side surface of the limiting clamp, and the whole process is automatically completed. At the same time, it is not affected by the stopping of winding, and the limiting state can still be maintained after the winding is interrupted, ensuring that the sofa leather will not loosen during the whole winding process, thereby improving the winding quality.
[0021] As a further technical solution of the present invention, the flattening assembly includes an extension frame, which is connected to the front of the machine base. Limiting rollers are movably installed at the upper and lower ends of the inner side of the extension frame, and rubber brushes are fixedly sleeved on the outer sides of the limiting rollers.
[0022] Before the sofa leather is rolled up, the upward movement of the machine base can synchronously drive the extension frame to move up, so the extension frame can be kept in front of the winding roller at all times. When the sofa leather passes between the two limiting rollers, the two limiting rollers can rotate relative to each other and keep the upper and lower ends of the sofa leather limited to flatten it. At the same time, the rubber brush located on the outer side of the limiting roller can contact the outer side of the sofa leather to clean its surface, completing the automatic flattening and automatic cleaning process.
[0023] By utilizing the adjustment process of the support component to complete the correspondence between the winding roller and the power component, the relative position of the flattening component can also be always maintained, ensuring that during the winding process of the sofa leather, the two ends of the sofa leather can always maintain the upper and lower limits, keeping the sofa leather in a flat state. At the same time, the cleaning process of the sofa leather with a rubber brush can avoid the sofa leather from wrinkling during winding, further improving the quality of the sofa leather during winding and improving its flatness.
[0024] The beneficial effects of the present invention are as follows: 1. The present invention utilizes the cooperation between the support component and the power component so that the device only needs to control the support component to drive the machine base to descend, and cooperate with the power component to quickly complete the power transmission process. At the same time, the power transmission can be quickly released during disassembly. The whole process is completed quickly without the need for a complicated disassembly process, and the winding roller can be quickly separated, thereby improving the winding efficiency.
[0025] 2. The present invention utilizes the cooperation between the winding roller, the limiting clamp and the limiting assembly, the elastic force of the first limiting spring, and the limiting process of the limiting clamp on the sofa leather, so as to ensure that during the winding process of the sofa leather, its outer side surface can always be in contact with the inner side surface of the limiting clamp. The whole process is completed automatically and is not affected by the stopping of winding. The limiting state can still be maintained after the winding is interrupted, so as to ensure that the sofa leather will not loosen during the whole winding process, thereby improving the winding quality.
[0026] 3. The present invention utilizes the adjustment process of the support component to complete the correspondence between the winding roller and the power component, and can also always maintain the relative position of the flattening component, ensuring that during the winding process of the sofa leather, the two ends of the sofa leather can always maintain the upper and lower limits, keeping the sofa leather in a flat state, and at the same time, in conjunction with the rubber brush to clean the sofa leather, it can avoid the sofa leather from wrinkling during winding, further improving the quality of the sofa leather during winding and improving its flatness.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0030] like Figures 1 to 8 As shown, in the embodiment of the present invention, a winding device for producing microfiber suede sofa leather comprises a base 1, a support assembly 2 is movably mounted on the top of the base 1, a base 3 is fixedly mounted on the top of the support assembly 2, a winding roller 8 is movably mounted in the middle of the base 3, and slots 4 are provided on the left and right sides of the base 3 near the upper and lower ends, and the inside of the slots 4 is movably connected with a limiting clamp 12 located on the outer side of the winding roller 8, and limiting assemblies 5 are fixedly mounted on the left and right sides of the base 3, and the upper and lower ends of the limiting assembly 5 are movably connected with the two limiting clamps 12. A power component 6 located on one side of the winding roller 8 is fixedly installed on one side, and a flattening component 7 located on the front of the winding roller 8 is fixedly installed on one side of the machine base 3. Limiting grooves 11 are provided on both ends of the winding roller 8, and a transmission shaft 10 is movably sleeved inside the limiting grooves 11. The winding roller 8 is movably connected to the machine base 3 through the transmission shaft 10. The transmission shaft 10 located on one side is transmission-connected to the power component 6. A reset spring 9 is fixedly connected between the transmission shaft 10 and the limiting groove 11. When the reset spring 9 is in the extreme compression state, the transmission shaft 10 is completely located inside the limiting groove 11.
[0031] Before winding the sofa leather, the free end of the sofa leather needs to be fixedly connected to the outer side of the winding roller 8, and the free end needs to pass through the middle of the flattening component 7, and ensure that the winding roller 8 can drive the sofa leather to rotate to complete the preparation work before winding the sofa leather.
[0032] When it is necessary to separate the winding roller 8 and the machine base 3, the left and right transmission shafts 10 can be pressed inward at the same time. At this time, the return spring 9 located inside the limit groove 11 is compressed and drives the two transmission shafts 10 to move toward the inside of the limit groove 11. When it is fully retracted into the inside of the limit groove 11, the connection between the winding roller 8 and the machine base 3 is released, and the winding roller 8 can be removed. Otherwise, the assembly between the winding roller 8 and the machine base 3 can be completed.
[0033] like Figure 1 and Figure 4 As shown, the support assembly 2 includes two left and right guide blocks 201, a guide groove is provided at the top of the base 1 and the guide block 201 is movably engaged with the inside of the guide groove, an electric push rod 202 located inside the guide groove is fixedly installed between the two guide blocks 201, the top of the guide block 201 is fixedly connected to a first fixed seat 203, the end of the first fixed seat 203 away from the guide block 201 is movably connected to a first connecting rod 205 through a rotating shaft, the end of the first connecting rod 205 away from the first fixed seat 203 is movably connected to a second fixed seat 204 through a rotating shaft, and the top of the second fixed seat 204 is connected to the bottom end of the machine base 3.
[0034] When the sofa leather needs to be wound, the electric push rod 202 can be turned on and its extension can be controlled. When the electric push rod 202 is extended, the two guide blocks 201 can be pushed relatively away. At this time, the distance between the two guide blocks 201 increases accordingly, and the two first connecting rods 205 are deflected toward the middle and apply a downward pulling force to the second fixed seat 204 until the base 3 is moved downward. When the electric push rod 202 is stretched to the limit state, that is, the distance between the two guide blocks 201 is at the maximum value, the base 3 can be at the lowest point.
[0035] like Figure 1 and Figure 2 as well as Figure 8 As shown, the power assembly 6 includes an L-shaped frame 601, a limit seat 602 is fixedly installed on the top of the L-shaped frame 601, and a limit block 603 is movably engaged inside the limit seat 602. The end of the limit block 603 away from the winding roller 8 is fixedly connected to a second limit spring 604 located inside the limit seat 602, and the other end of the second limit spring 604 is connected to one side of the inner cavity of the limit seat 602. The end of the limit block 603 away from the second limit spring 604 passes through one side of the limit seat 602 and is fixedly connected to a motor 605. A transmission sleeve 606 is fixedly installed on the output end of the motor 605, and an electromagnet is fixedly installed on the side of the transmission sleeve 606 close to the winding roller 8. When the winding roller 8 is at the highest point, the transmission sleeve 606 is movably connected to the transmission shaft 10.
[0036] Embodiment: When the machine base 3 drops to the lowest point, the winding roller 8 also drops to the lowest point, and the winding roller 8 corresponds to the power assembly 6. At this time, the electromagnet on one side of the transmission sleeve 606 can be turned on, and the transmission sleeve 606 is displaced toward the direction of the transmission shaft 10, and is mutually adsorbed with one side of the transmission shaft 10, and drives the transmission sleeve 606 and the transmission shaft 10 to be actively engaged. At this time, the second limit spring 604 can be stretched, and drives the limit block 603 and the motor 605 to be displaced as a whole toward the direction close to the winding roller 8. At this time, the motor 605 can be turned on to drive the winding roller 8 to rotate through the transmission sleeve 606 and the transmission shaft 10, completing the winding process of the sofa leather; When it is necessary to remove the winding roller 8, the electromagnet of the transmission sleeve 606 can be turned off, which can drive the motor 605 and the transmission sleeve 606 to automatically reset. At this time, the socket connection between the transmission sleeve 606 and the transmission shaft 10 can be released. At the same time, the support assembly 2 is controlled to automatically reset to drive the machine base 3 and the winding roller 8 to rise, completing the disassembly process.
[0037] By utilizing the cooperation between the support component 2 and the power component 6, the device only needs to control the support component 2 to drive the base 3 to descend, and cooperate with the power component 6 to quickly complete the power transmission process. At the same time, the power transmission can also be quickly released during disassembly. The whole process is completed quickly without the need for a complicated disassembly process. The winding roller 8 can be quickly separated, thereby improving the winding efficiency.
[0038] like Figure 1 and Figure 5 as well as Figure 6 As shown, the limiting assembly 5 includes a fixed tube 501, the outer side of the fixed tube 501 is connected to the base 3 through a locking frame, the interior of the fixed tube 501 is movably sleeved with a movable plate 503, the end of the movable plate 503 away from the base 3 is fixedly connected to a movable rod 502 located inside the fixed tube 501, the end of the movable rod 502 away from the movable plate 503 passes through one end of the fixed tube 501 and is fixedly connected to a movable seat 504, the outer side of the movable rod 502 is movably sleeved with a first limiting spring 507, the first limiting spring 5 The two ends of 07 are respectively connected to one end of the movable plate 503 and one end of the inner cavity of the fixed tube 501, and the third fixed seat 505 is fixedly installed at the upper and lower ends of the movable seat 504 close to the machine base 3. The end of the third fixed seat 505 away from the movable seat 504 is movably connected to the second connecting rod 508 through a rotating shaft, and the end of the second connecting rod 508 away from the third fixed seat 505 is movably connected to the fourth fixed seat 506 through a rotating shaft. The end of the fourth fixed seat 506 away from the second connecting rod 508 is connected to one side of the limiting clamp 12.
[0039] Embodiment: When winding, that is, when the first limit spring 507 is in the initial state, the distance between the movable seat 504 and the fixed tube 501 is the maximum value, and the inner side of the limit splint 12 is in contact with the outer side of the sofa leather. At the same time, the distance between the upper and lower fourth fixed seats 506 is also the minimum value. As the winding proceeds, the thickness of the sofa leather located on the outer side of the winding roller 8 increases. At this time, the upper and lower limit splints 12 move away from each other and drive the two fourth fixed seats 506 away from each other. Under the guiding action of the second connecting rod 508, the movable seat 504 is driven to move toward the direction of the fixed tube 501, and the first limit spring 507 is stretched. At the same time, under the elastic force of the first limit spring 507, the limit splint 12 is always in contact with the outer side of the sofa leather to maintain the limiting process of the sofa leather.
[0040] By utilizing the cooperation between the winding roller 8, the limiting clamp plate 12 and the limiting assembly 5, through the elastic force of the first limiting spring 507, and the limiting process of the limiting clamp plate 12 on the sofa leather, it is ensured that during the winding process, the outer side surface of the sofa leather can always be in contact with the inner side surface of the limiting clamp plate 12, and the whole process is automatically completed. At the same time, it is not affected by the stopping of winding, and the limiting state can still be maintained after the winding is interrupted, ensuring that the sofa leather will not loosen during the entire winding process, thereby improving the winding quality.
[0041] like Figure 1 and Figure 3 As shown, the flattening assembly 7 includes an extension frame 701, which is connected to the front of the machine base 3. The upper and lower ends of the inner side of the extension frame 701 are movably installed with limit rollers 702, and the outer side of the limit rollers 702 is fixedly sleeved with rubber brushes 703.
[0042] Before the sofa leather is rolled up, the upward movement of the machine base 3 can synchronously drive the extension frame 701 to move upward, so that the extension frame 701 can be kept always in front of the winding roller 8. When the sofa leather passes between the two limiting rollers 702, the two limiting rollers 702 can rotate relative to each other and keep the upper and lower ends of the sofa leather limited to flatten it. At the same time, the rubber brush 703 located on the outer side of the limiting roller 702 can contact the outer side of the sofa leather to clean its surface, completing the automatic flattening and automatic cleaning process.
[0043] By utilizing the adjustment process of the support component 2 to complete the correspondence between the winding roller 8 and the power component 6, the relative position of the flattening component 7 can also be always maintained, ensuring that during the winding process of the sofa leather, the two ends of the sofa leather can always maintain the upper and lower limits, keeping the sofa leather in a flat state. At the same time, the cleaning process of the sofa leather with the rubber brush 703 can avoid the sofa leather from wrinkling during winding, further improving the quality of the sofa leather during winding and improving its flatness.
[0044] Working principle and usage process: Before the sofa leather is wound, the free end of the sofa leather needs to be fixedly connected to the outer side of the winding roller 8, and the free end needs to pass through the middle of the flattening component 7, and ensure that the winding roller 8 can drive the sofa leather to rotate to complete the preparation work before the sofa leather is wound; When it is necessary to separate the winding roller 8 and the machine base 3, the left and right transmission shafts 10 can be pressed inward at the same time. At this time, the return spring 9 located inside the limit groove 11 is compressed, and the two transmission shafts 10 are driven to move toward the inside of the limit groove 11. When it is completely retracted into the inside of the limit groove 11, the connection between the winding roller 8 and the machine base 3 is released, and the winding roller 8 can be removed. Otherwise, the assembly between the winding roller 8 and the machine base 3 can be completed. When the sofa leather needs to be wound, the electric push rod 202 can be turned on and controlled to extend. When the electric push rod 202 extends, the two guide blocks 201 can be pushed relatively away from each other. At this time, the distance between the two guide blocks 201 increases accordingly, and the two first connecting rods 205 deflect toward the middle and apply a downward pulling force to the second fixed seat 204 until the base 3 is driven to move downward. When the electric push rod 202 is stretched to the limit state, that is, the distance between the two guide blocks 201 is the maximum value, the base 3 can be at the lowest point. When the base 3 drops to the lowest point, the winding roller 8 also drops to the lowest point, and the winding roller 8 corresponds to the power assembly 6. At this time, the electromagnet on one side of the transmission sleeve 606 can be turned on, and the transmission sleeve 606 moves toward the direction of the transmission shaft 10, and adsorbs on one side of the transmission shaft 10, and drives the transmission sleeve 606 and the transmission shaft 10 to be actively engaged. At this time, the second limit spring 604 can be stretched, and drives the limit block 603 and the motor 605 to move as a whole toward the direction close to the winding roller 8. At this time, the motor 605 can be turned on to drive the winding roller 8 to rotate through the transmission sleeve 606 and the transmission shaft 10, completing the winding process of the sofa leather; Before the sofa leather is rolled up, the upward movement of the machine base 3 can synchronously drive the extension frame 701 to move up, so that the extension frame 701 can be kept always in front of the winding roller 8. When the sofa leather passes between the two limiting rollers 702, the two limiting rollers 702 can rotate relative to each other and keep the upper and lower ends of the sofa leather limited to flatten it. At the same time, the rubber brush 703 located on the outer side of the limiting roller 702 can contact the outer side of the sofa leather to clean its surface, completing the automatic flattening and automatic cleaning process. When winding, that is, when the first limiting spring 507 is in the initial state, the distance between the movable seat 504 and the fixed tube 501 is the maximum value, and the inner side of the limiting splint 12 is in contact with the outer side of the sofa leather. At the same time, the distance between the upper and lower fourth fixed seats 506 is also the minimum value. As the winding proceeds, the thickness of the sofa leather located on the outer side of the winding roller 8 increases. At this time, the upper and lower limiting splints 12 move away from each other, and drive the two fourth fixed seats 506 to move away from each other. Under the guidance of the second connecting rod 508, the movable seat 504 is driven to move toward the direction of the fixed tube 501, and the first limiting spring 507 is stretched.
