Description

Technical Field

[0001] The invention relates to the technical field of fabric processing equipment, and in particular to an automatic cutting-winding system and a working method for imitation fur fabric. Background Art

[0002] Affected by factors such as animal protection, environmental protection requirements, supply and demand imbalance, and ethical requirements, the large-scale production of clothing using animal fur is no longer sustainable. Fur-like fabrics synthesized from artificial materials are comparable to animal fur in terms of warmth, aesthetics, and economy, and have obvious advantages in terms of renewability and environmental protection. It has become a trend for fur-like fabrics to replace animal fur. At present, the automated production of ordinary fabrics has been relatively mature at home and abroad, and the automated production equipment involved in each production link of spinning, weaving, printing and dyeing, and post-processing has been relatively complete. The production process of fur-like fabrics is more complicated than that of ordinary fabrics. Affected by factors such as the hardness, thickness, and density of fur-like fabrics, the existing automated production technology and equipment for ordinary fabrics are not suitable for the production of fur-like fabrics.

[0003] The production of imitation fur fabrics belongs to high-end equipment manufacturing, with high technical content, high product added value, high environmental protection and energy-saving requirements, and it ranks at the high-end value chain in the textile field. Although the existing imitation fur fabric production equipment has achieved automation in the spinning, weaving, dyeing and finishing links, the fabric cutting and winding process at the end of the production process is complex, requires high precision, and is difficult to operate. At present, the cutting of imitation fur fabrics requires shutdown operation and manual cutting, which is not only inefficient, but also uneven cutting, and it is difficult to avoid waste, causing waste and environmental pollution. The winding of imitation fur fabrics is even more cumbersome, and a series of operations must be completed, such as winding at the end of the roll, sealing and unloading, fixing the core shaft of the new roll, and winding up the head of the new roll. The entire winding process not only requires the equipment to be shut down, but also requires multiple workers to cooperate in manual operation. It is not only labor-intensive, but also extremely inefficient, with high labor costs and greater safety risks.

[0004] Realizing automatic cutting and winding of imitation fur fabrics is a pain point for current imitation fur production companies, and it is also a difficult problem faced by imitation fur production equipment manufacturers. In order to respond to the development needs of the industry, it is urgent to develop a fully automatic cutting and winding equipment for imitation fur fabrics to achieve unmanned operation and less excess cutting, thereby effectively improving the automation and intelligence level of the imitation fur fabric production process, significantly improving production efficiency, greatly reducing labor costs, and minimizing waste rates. Summary of the invention

[0005] In view of the deficiencies of the above-mentioned prior art, one object of the present invention is to propose an automatic cutting-winding system for imitation fur fabric, so as to solve the problem that the winding process of the imitation fur fabric not only requires equipment shutdown, but also requires the cooperation of multiple workers to complete the manual operation, resulting in high labor intensity, low degree of automation, high labor cost, low production efficiency and poor safety.

[0033] Another object of the present invention is to provide a working method of the automatic cutting-winding system for fur-like fabric.

[0034] A working method of an automatic cutting-rewinding system for imitation fur fabric, based on the automatic cutting-rewinding system for imitation fur fabric, the working method comprises the following steps:

[0035] Step 1: In the initial state, install a roll of tape on the pin shaft with holes of each sealing support plate, and pull the end of the tape backward, passing through the one-way wheel 2, the guide wheel, the one-way wheel 1 and the clamping wheel in turn, reaching the front side of the clamping wheel and maintaining a natural drooping state.

[0036] The front end of the fur-like fabric passes around the guide rollers in turn and enters between the upper rubber roller and the lower rubber roller of the rear material guide mechanism. The upper rubber rollers and the lower rubber rollers of the two material guide mechanisms rotate synchronously to transport the fur-like fabric from back to front. The two supporting plates support the front end of the fur-like fabric and enter between the upper rubber roller and the lower rubber roller of the front material guide mechanism, and pass forward through the front material guide mechanism.

[0037] During the conveying process, the cutting knife stays in the waiting area on the left side of the fur-like fabric, and the encoder of the rear material guide mechanism records the feeding length of the fur-like fabric. When the length of the front end of the fur-like fabric passing through the front material guide mechanism reaches ΔL, the feeding is stopped.

[0038] Step 2: The 3D vision sensor identifies and locates the core shaft placed on the shelf and feeds the information back to the PLC controller. The PLC controller controls the six-degree-of-freedom robotic arm through instructions to grab a core shaft and move the core shaft between the two positioning drive components. The execution ends of the two positioning drive components move linearly relative to each other and are respectively plugged and fixedly connected to the two ends of the core shaft. After that, the six-degree-of-freedom robotic arm rotates to a safe area.

[0039] Step three, the two longitudinal linear modules are started, and the two longitudinal linear modules synchronously drive the support shaft to translate forward. At the same time, the second drive assembly drives each sealing support plate to rotate downward around the support shaft. After the ends of all the tapes reach the front side of the winding core shaft from the top of the winding core shaft, the pressure wheel presses the tapes onto the circumferential surface of the winding core shaft.

[0040] The two positioning drive components are started, and the execution end of the positioning drive component drives the winding core shaft to rotate. After the tape is wound around the winding core shaft twice, the winding core shaft stops rotating. During the rotation of the winding core shaft, the pressure wheel keeps the tape in a tight state.

[0041] Step 4: The two longitudinal linear modules synchronously drive the support axis to translate backward. At the same time, the second drive assembly drives each sealing support plate to rotate upward around the support axis. The pressure wheel pulls the tape to the upper side of the front end of the fur-like fabric and presses the tape against the upper surface of the fur-like fabric. The pressure wheel maintains its current position.

[0042] Afterwards, the upper rubber roller and the lower rubber roller of the two material guiding mechanisms rotate synchronously to continue to convey the imitation fur fabric forward. At the same time, the two positioning drive components drive the winding core shaft to rotate to wind the tape. The winding of the tape is consistent with the movement of the imitation fur fabric. Under the pulling force of the winding core shaft, the tape is continuously unwound and adhered to the upper surface of the imitation fur fabric.

[0043] Step 5: The tape pulls the front end of the imitation fur fabric to the winding core shaft and wraps it around the surface of the winding core shaft twice. After that, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms stop rotating synchronously, and the tape and the imitation fur fabric remain in the current state.

[0044] After the two longitudinal linear modules synchronously drive the support shaft to translate forward to the set position, they stop moving, and the tape portion located on the lower side of the pressure wheel is separated from the surface of the imitation fur fabric and remains in a tensioned state. The cutting component cuts off the tape, and then the cutting component is reset, and each pressure wheel maintains the current state.

[0045] Afterwards, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms start to rotate synchronously, the fur-like fabric continues to be wound on the winding core shaft, and the encoder of the rear material guide mechanism continues to record the feeding length of the fur-like fabric.

[0046] Step 6. When the feeding length of the imitation fur fabric recorded by the encoder of the rear material guide mechanism reaches the set value, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms stop rotating synchronously. Then, the horizontal linear module drives the cutting knife to move horizontally to cut the imitation fur fabric, and the cutting knife returns to the initial position.

[0047] Step 7: After the two longitudinal linear modules synchronously drive the support shaft to translate backward to the set position, each clamping wheel presses the tape onto the surface of the cut fur-like fabric and keeps the lower rubber roller of the front material guide mechanism in a clamped state.

[0048] Afterwards, the winding core shaft and the upper and lower rubber rollers of the front side material guide mechanism start to rotate synchronously, and the cut imitation fur fabric continues to be transported forward and continues to be wound on the winding core shaft. During this process, the lower rubber roller of the front side material guide mechanism drives each clamping wheel to rotate, pulling the corresponding tape to unwind, and the tape continues to stick to the surface of the cut imitation fur fabric.

[0049] Step 8. When the tail end of the cut fur-like fabric leaves the front material guide mechanism, the two longitudinal linear modules synchronously drive the support shaft to translate forward. At the same time, the second drive assembly drives each sealing support plate to rotate downward around the support shaft. During this process, the cut fur-like fabric continues to be wound on the winding core shaft, and the tape moves with the tail end of the cut fur-like fabric and remains in a tensioned state.

[0050] The upper rubber roller and the lower rubber roller of the rear material guide mechanism start to rotate synchronously, and the imitation fur fabric is continuously conveyed forward and passes through the front material guide mechanism. When the length reaches ΔL, the two material guide mechanisms stop feeding.

[0051] Step 9: The cut imitation fur fabric is wound on the winding core shaft to form a material roll, and the pressing wheel presses the tape against the surface of the material roll. After the tape is wound twice, the winding core shaft stops rotating.

[0052] Afterwards, each sealing support plate swings backward around the support axis to a set angle value and then stops swinging, the cutting assembly cuts the tape, and then the cutting assembly is reset to complete the roll sealing.

[0053] Step 10. The second cylinder drives the middle and rear part of the unloading plate to rise upward, and the unloading plate is close to the bottom of the material roll and maintains an inclined state with the front low and the back high; then, the execution ends of the two positioning drive components move synchronously to the side away from each other and disengage from the two ends of the winding core shaft. The material roll falls to the upper surface of the unloading plate and rolls forward to the conveyor belt assembly, and the conveyor belt assembly transports the sealed material roll to the storage area.

[0054] Repeat the process from step 2 to step 10 to automatically cut and rewind the next roll.

[0055] By adopting the above technical solution, the beneficial technical effects of the present invention are:

[0056] 1. The present invention can realize automated operation, completely replace manual operation, and has high operation efficiency. The equipment adopts an assembly line operation mode, and can be seamlessly connected with the weaving production line of imitation fur fabrics. Compared with the traditional manual cutting and winding operation mode, the winding time is greatly reduced, the front-end production equipment does not need to be shut down for a long time, the operation process is fully automated, and the equipment is kept in long-term stable operation, the production efficiency is significantly improved, and the production cost is greatly reduced.

[0057] 2. The present invention can achieve high-precision cutting without waste. The material guide mechanism can accurately calculate the feeding length, effectively ensuring the accuracy of the feeding length of the imitation fur fabric roll. The automatic cutting method is used instead of the manual cutting method, which can effectively ensure the neatness of the cutting head, avoid the generation of more waste due to uneven manual cutting, and improve the utilization rate of the imitation fur fabric.

DETAILED DESCRIPTION

[0068] In order to make the advantages and technical solutions of the present invention more clear and explicit, the present invention is described in detail below in conjunction with specific embodiments.

[0069] Embodiment 1, combination Figures 1 to 7 , an automatic cutting-winding system for imitation fur fabrics, comprising a main frame 1, a feeding mechanism 2, a cutting mechanism 3, a material guiding mechanism 4, a winding mechanism 5, a sealing mechanism 6, a lowering mechanism 7 and a control unit, wherein the feeding mechanism 2 comprises a feeding frame 21 and two groups of guide rollers 22, the feeding frame 21 being arranged adjacent to each other at the rear side of the main frame 1, and the two groups of guide rollers 22 being arranged at the upper part and the lower part of the feeding frame 21, respectively. The main frame 1 and the feeding frame 21 are both steel frame structures, the front side of the feeding frame 21 is fixedly connected to the rear side of the main frame 1, each group of the guide rollers 22 comprises two guide rollers 22 arranged in parallel, one in front and one in the back, each guide roller 22 is arranged horizontally, and its left and right ends are respectively connected to the feeding frame 21 for rotation, and the two guide rollers 22 at the upper part of the feeding frame 21 and the two guide rollers 22 at the lower part thereof are arranged front and back in staggered arrangement.

[0070] The control unit includes a distribution box and a PLC controller. Both the distribution box and the PLC controller adopt existing technologies. A master control switch is installed inside the distribution box. The master control switch is connected to industrial electricity to power the stepper motor, servo motor and various linear modules of the automatic cutting and winding system. The PLC controller controls the operation of the electrical part through program instructions.

[0071] The cutting mechanism 3 includes a transverse linear module 31, a cutting knife 32, and two supporting plates 33 arranged symmetrically and adjacently on the top of the main frame 1. The supporting plates 33 are rectangular structures, and the left and right ends of the supporting plates 33 are respectively fixedly connected to the top bolts of the main frame 1. The two supporting plates 33 are arranged horizontally, forming a gap extending laterally between adjacent sides. In the working state, the cutting knife 32 reciprocates laterally in the gap to cut the fur-like fabric 9 located on the top of the supporting plates 33.

[0072] There are two material guiding mechanisms 4, which are symmetrically arranged on the front and rear sides of the two supporting plates 33. The material guiding mechanism 4 includes an upper rubber roller 41, a lower rubber roller 42 and a first driving component. The upper rubber roller 41 and the lower rubber roller 42 are arranged adjacent to each other in parallel, one above and one below. The first driving component drives the upper rubber roller 41 and the lower rubber roller 42 to rotate synchronously, and conveys the fur-like fabric 9 clamped between the upper rubber roller 41 and the lower rubber roller 42 forward.

[0073] Specifically, the material guiding mechanism 4 also includes two bearing seats 43, which are respectively fixed on the left and right sides of the top of the main frame 1, and the upper rubber roller 41 and the lower rubber roller 42 are both located between the two bearing seats 43. The left and right ends of the upper rubber roller 41 and the lower rubber roller 42 are respectively rotatably connected to the two bearing seats 43 through bearings.

[0074] The upper rubber roller 41 and the lower rubber roller 42 both include roller bodies with circular cross-sections, and the circumferential surface of each roller body has a polyurethane layer integrally formed therewith. The surface distance between the upper rubber roller 41 and the lower rubber roller 42 is less than the thickness of the fur-like fabric 9, and a certain pressing force is maintained on the fur-like fabric 9 between the upper rubber roller 41 and the lower rubber roller 42, so as to ensure that the fur-like fabric 9 will not slide relative to the upper rubber roller 41 and the lower rubber roller 42 during the forward conveying process, and the pressing force of the upper rubber roller 41 and the lower rubber roller 42 on the fur-like fabric 9 will not damage the fur-like fabric 9. The gap between the upper rubber roller 41 and the lower rubber roller 42 is set according to the thickness of the fur-like fabric 9, and the replacement of rubber rollers of different diameters can be applied to fur-like fabrics of different thicknesses.

[0075] The left ends of the upper rubber roller 41 and the lower rubber roller 42 are both passed through the left side wall of the bearing seat 43 located on the left side. The first driving assembly includes a first servo motor 44, an upper gear 45 and a lower gear 46. The upper gear 45 is installed on the left end of the upper rubber roller 41, and the lower gear 46 is installed on the left end of the lower rubber roller 42 and meshes with the upper gear 45. The first servo motor 44 is fixed to the top of the main frame 1, and its output shaft is connected to the left end of the lower rubber roller 42 through a coupling 47. The upper rubber roller 41 and the lower rubber roller 42 maintain a pressing force on the imitation fur fabric 9 to avoid relative slippage. When the imitation fur fabric 9 enters the upper rubber roller 41 and the lower rubber roller 42, its upper surface is smooth and its lower surface is fur.

[0076] The signal end of the first servo motor 44 is communicatively connected to the PLC controller. Both of the first servo motors 44 are equipped with high-precision encoders. The encoders calculate the feeding length of the imitation fur fabric 9 of the material guide mechanism 4 by recording the rotation angle of the output shaft of the corresponding first servo motor 44, and send the data to the PLC controller in real time. The PLC controller controls the working state of the first servo motor 44 through instructions to form a closed loop, thereby accurately controlling the feeding state and length of the imitation fur fabric 9.

[0077] The upper surfaces of the two supporting plates 33 are both flat and located at the same height, and the sides of the two supporting plates 33 facing away from each other are respectively close to the upper surfaces of the two lower rubber rollers 42. Specifically, the bottoms of the two supporting plates 33 facing away from each other have an arc surface, which is matched with the circumferential surface of the lower rubber roller 42. The thickness of the sides of the two supporting plates 33 facing away from each other is relatively thin, and they are respectively close to the discharge side of the rear material guide mechanism 4 and the feed side of the front material guide mechanism 4, supporting the front end of the fur-like fabric 9 to enter between the upper rubber roller 41 and the lower rubber roller 42 of the front material guide mechanism 4.

[0078] The horizontal linear module 31 is arranged below the support plate 33, and the horizontal linear module 31 drives the cutting knife 32 to move horizontally between the two support plates 33. The horizontal linear module 31 is fixedly installed on the main frame 1, and the cutting knife 32 is arranged vertically, and the lower end is fixedly connected to the slider seat of the horizontal linear module 31. The blade of the cutting knife 32 is located on the right side thereof and is arranged obliquely, and the upper end of the cutting knife 32 is higher than the upper surface of the support plate 33. The portion of the imitation fur fabric 9 between the two material guide mechanisms 4 maintains a certain tension. In the initial state, the cutting knife 32 is located outside the left side of the imitation fur fabric 9, and will not affect the feeding of the imitation fur fabric 9.

[0098] Embodiment 2, combined Figures 1 to 9 A working method of an automatic cutting-rewinding system for imitation fur fabric is provided. Based on the automatic cutting-rewinding system for imitation fur fabric described in Example 1, the working method comprises the following steps:

[0099] Step 1: In the initial state, a roll of adhesive tape is installed on the pin shaft 85 with holes of each adhesive sealing support plate 62, and the end of the adhesive tape is pulled backward, passing through the one-way wheel 2 84, the guide wheel 83, the one-way wheel 1 82 and the pressure wheel 81 in sequence, and reaches the front side of the pressure wheel 81 and keeps a natural drooping state. The adhesive tape is unwound under the action of the traction force, and the circumferential surfaces of the one-way wheel 1 82 and the one-way wheel 2 84 are in contact with the adhesive surface of the adhesive tape, and the adhesive surface of the adhesive tape is located on the side away from the circumferential surface of the pressure wheel 81.

[0100] The front end of the fur-like fabric 9 passes around the guide rollers 22 in turn and enters between the upper rubber roller 41 and the lower rubber roller 42 of the rear material guide mechanism 4. The upper rubber rollers 41 and the lower rubber rollers 42 of the two material guide mechanisms 4 rotate synchronously to transport the fur-like fabric 9 from the back to the front. The two supporting plates 33 support the front end of the fur-like fabric 9 to enter between the upper rubber roller 41 and the lower rubber roller 42 of the front material guide mechanism 4 and pass through the front material guide mechanism 4 forward.

[0101] During the conveying process, the cutting knife 32 stays in the waiting area on the left side of the fur-like fabric 9, and the encoder of the rear side material guide mechanism 4 records the feeding length of the fur-like fabric 9. When the length of the front end of the fur-like fabric 9 passing through the front side material guide mechanism 4 reaches ΔL, the feeding is stopped, and ΔL is set to 20mm~30mm.

[0102] Step 2: The 3D vision sensor identifies and locates the core shaft 51 placed on the shelf 91, and feeds back the information to the PLC controller. The PLC controller controls the six-degree-of-freedom robotic arm 92 through instructions to grab a core shaft 51 and move the core shaft 51 between the two positioning drive components. The execution ends of the two positioning drive components move linearly relative to each other and are respectively plugged and fixedly connected to the two ends of the core shaft 51. After that, the six-degree-of-freedom robotic arm 92 rotates to a safe area.

[0103] The six-degree-of-freedom robotic arm 92 clamps the middle part of the winding core shaft 51, and the winding core shaft 51 maintains a horizontal and stationary state between the two positioning drive components. The two horizontal linear modules 52 respectively drive the two positioning shafts 54 to move toward each other synchronously. At the same time, the two second servo motors 55 respectively drive the two positioning shafts 54 to rotate slowly and synchronously. After the end of the positioning shaft 54 ​​contacts the end face of the spline hole at the corresponding end of the winding core shaft 51, the end of the positioning shaft 54 ​​applies a small tightening force to the end face of the spline hole. When the positioning shaft 54 ​​continues to rotate until the external spline at its end is opposite to the spline hole of the winding core shaft 51, the external splines at the ends of the two positioning shafts 54 are respectively inserted into the spline holes at the corresponding ends of the winding core shaft 51.

[0104] Since the winding core shaft 51 is fixed on the six-degree-of-freedom mechanical arm 92, the torque sensor of the second servo motor 55 detects that the torque of its output shaft reaches the set value and stops rotating. The second horizontal linear module 52 drives the two positioning shafts 54 to continue to move synchronously relative to each other until the ends of the two positioning shafts 54 are completely inserted into the spline holes at the corresponding ends of the winding core shaft 51, and then the six-degree-of-freedom mechanical arm 92 releases the clamping of the winding core shaft 51.

[0105] Step three, the two longitudinal linear modules 64 are started, and the two longitudinal linear modules 64 synchronously drive the support shaft 61 to translate forward. At the same time, the second driving assembly drives each sealing support plate 62 to rotate downward around the support shaft 61. After the ends of all the tapes reach the front side of the winding core shaft 51 from the top of the winding core shaft 51, the pressure wheel 81 presses the tapes onto the circumferential surface of the winding core shaft 51.

[0106] The PLC controller controls the rotation of the output shaft of the stepper motor 66 and the forward and backward movement of the slider seats of the two longitudinal linear modules 64 through program instructions to cooperate with each other. The clamping wheels 81 move synchronously according to the motion trajectory set by the program. After the clamping wheel 81 drives the adhesive surface of the end of the tape to stick to the surface of the winding core shaft 51, the clamping wheel 81 presses the tape onto the winding core shaft 51.

[0107] The two positioning drive components are started, and the execution end of the positioning drive component drives the winding core shaft 51 to rotate. After the tape is wound around the winding core shaft 51 twice, the winding core shaft 51 stops rotating. During the rotation of the winding core shaft 51, the pressure wheel 81 keeps the tape in a tight state, and the winding core shaft 51 drives the pressure wheel 81 to rotate synchronously.

[0108] Step 4. The two longitudinal linear modules 64 synchronously drive the support shaft 61 to translate backward. At the same time, the second driving assembly drives each sealing support plate 62 to rotate upward around the support shaft 61. Each clamping wheel 81 moves synchronously according to the motion trajectory set by the program. The clamping wheel 81 pulls the tape to the upper side of the front end of the fur-like fabric 9 and presses the tape against the upper surface of the fur-like fabric 9. The clamping wheel 81 presses the lower rubber roller 42 of the front material guide mechanism 4 and maintains the current position.

[0109] Afterwards, the upper rubber roller 41 and the lower rubber roller 42 of the two material guiding mechanisms 4 rotate synchronously to continue conveying the fur-like fabric 9 forward, and the lower rubber roller 42 drives the clamping wheels 81 to rotate synchronously. At the same time, the two positioning drive components drive the winding core shaft 51 to rotate to wind the tape. The winding of the tape is consistent with the movement of the fur-like fabric 9. Under the pulling force of the winding core shaft 51, the tape is continuously unwound and adhered to the upper surface of the fur-like fabric 9.

[0110] Step 5: The tape pulls the front end of the fur-like fabric 9 to the winding core shaft 51 and wraps around the surface of the winding core shaft 51 twice. After that, the winding core shaft 51 and the upper and lower rubber rollers 41 and 42 of the two material guide mechanisms 4 stop rotating synchronously, and the tape and the fur-like fabric 9 maintain the current state.

[0111] After the two longitudinal linear modules 64 synchronously drive the support shaft 61 to translate forward to the set position, they stop moving, and the tape portion located on the lower side of the pressure wheel 81 is separated from the surface of the imitation fur fabric 9 and remains in a tensioned state. The cutting component cuts off the tape, and then the cutting component is reset, and each pressure wheel 81 maintains the current state.

[0112] Afterwards, the winding core shaft 51 and the upper and lower rubber rollers 41 and 42 of the two material guide mechanisms 4 start to rotate synchronously, the fur-like fabric 9 continues to be wound on the winding core shaft 51 , and the encoder of the first driving assembly continues to record the feeding length of the fur-like fabric 9 .

[0113] Step six, when the feeding length of the imitation fur fabric 9 recorded by the encoder of the rear side material guide mechanism 4 reaches the set value, the winding core shaft 51 and the upper rubber roller 41 and the lower rubber roller 42 of the two material guide mechanisms 4 stop rotating synchronously, and then the transverse linear module 1 31 drives the cutting knife 1 32 to move transversely to cut the imitation fur fabric 9, and the cutting knife 1 32 returns to the initial position.

[0114] Step 7: After the two longitudinal linear modules 64 synchronously drive the support shaft 61 to translate backward to the set position, each pressing wheel 81 presses the tape onto the surface of the cut fur-like fabric 9 and keeps the lower rubber roller 42 of the front material guide mechanism 4 pressed.

[0115] Afterwards, the winding core shaft 51 and the upper and lower rubber rollers 41 and 42 of the front material guide mechanism 4 start to rotate synchronously, and the cut fur-like fabric 9 continues to be transported forward and continues to be wound on the winding core shaft 51. During this process, the lower rubber roller 42 of the front material guide mechanism 4 drives each clamping wheel 81 to rotate, pulling the corresponding tape to unwind, and the tape continues to stick to the surface of the cut fur-like fabric 9.

[0116] Step 8. When the tail end of the cut fur-like fabric 9 leaves the front material guide mechanism 4, the two longitudinal linear modules 64 synchronously drive the support shaft 61 to translate forward. At the same time, the second driving assembly drives each sealing support plate 62 to rotate downward around the support shaft 61. During this process, the cut fur-like fabric 9 continues to be wound on the winding core shaft 51, and the tape moves with the tail end of the cut fur-like fabric 9 and remains in a tensioned state.

[0117] The upper rubber roller 41 and the lower rubber roller 42 of the rear material guide mechanism 4 start to rotate synchronously, and when the imitation fur fabric 9 continues to be conveyed forward and passes through the front material guide mechanism 4 to a length of ΔL, the two material guide mechanisms 4 stop feeding.

[0118] Step nine: The cut fur-like fabric 9 is wound on the winding core shaft 51 to form a material roll, and the pressing wheel 81 presses the adhesive tape onto the surface of the material roll. After the adhesive tape is wound twice, the winding core shaft 51 stops rotating.

[0119] Afterwards, each sealing support plate 62 swings backward around the support shaft 61 to a set angle value and then stops swinging, the cutting assembly cuts the tape, and then the cutting assembly is reset to complete the sealing.

[0120] Step 10. The piston rods of the two second cylinders 72 extend synchronously, driving the middle and rear parts of the unloading plate 71 to lift upward, so that the unloading plate 71 is close to the bottom of the material roll and maintains an inclined state with the front lower and the rear higher. After that, the execution ends of the two positioning drive assemblies move synchronously away from each other and disengage from the two ends of the winding core shaft 51. The material roll falls to the upper surface of the unloading plate 71 and rolls forward to the conveyor belt assembly, which transports the sealed material roll to the storage area.

[0121] Repeat the process from step 2 to step 10 to automatically cut and rewind the next roll.

10. A working method of an automatic cutting-winding system for imitation fur fabric, characterized in that: The automatic cutting-winding system for imitation fur fabric according to any one of claims 1 to 9 is used, and the working method comprises the following steps: Step 1: In the initial state, a roll of adhesive tape is installed on the pin shaft with holes of each adhesive sealing support plate, and the end of the adhesive tape is pulled backward, passing through the one-way wheel 2, the guide wheel, the one-way wheel 1 and the clamping wheel in sequence, reaching the front side of the clamping wheel and maintaining a natural drooping state; The front end of the fur-like fabric passes around the guide rollers in turn and enters between the upper rubber roller and the lower rubber roller of the rear material guide mechanism. The upper rubber rollers and the lower rubber rollers of the two material guide mechanisms rotate synchronously to transport the fur-like fabric from the back to the front. The two supporting plates support the front end of the fur-like fabric and enter between the upper rubber roller and the lower rubber roller of the front material guide mechanism, and pass through the front material guide mechanism forward. During the conveying process, the cutting knife stays in the waiting area on the left side of the imitation fur fabric, and the encoder of the rear side material guide mechanism records the feeding length of the imitation fur fabric. When the length of the front end of the imitation fur fabric passing through the front side material guide mechanism reaches ΔL, the feeding is stopped; Step 2: The 3D vision sensor identifies and locates the roll core shaft placed on the shelf, and feeds the information back to the PLC controller. The PLC controller controls the six-degree-of-freedom robotic arm through instructions to grab a roll core shaft and move the roll core shaft between the two positioning drive components. The execution ends of the two positioning drive components move linearly relative to each other and are respectively plugged and fixedly connected to the two ends of the roll core shaft. After that, the six-degree-of-freedom robotic arm rotates to a safe area. Step 3: The two longitudinal linear modules are started, and the two longitudinal linear modules synchronously drive the support shaft to translate forward. At the same time, the second drive assembly drives each sealing support plate to rotate downward around the support shaft. After the ends of all the tapes reach the front side of the winding core shaft from the top of the winding core shaft, the pressure wheel presses the tapes onto the circumferential surface of the winding core shaft. The two positioning drive components are started, and the execution end of the positioning drive component drives the winding core shaft to rotate. After the tape is wound around the winding core shaft for two turns, the winding core shaft stops rotating. During the rotation of the winding core shaft, the pressure wheel keeps the tape pressed; Step 4: The two longitudinal linear modules synchronously drive the support shaft to translate backward, and at the same time, the second drive assembly drives each sealing support plate to rotate upward around the support shaft, and the pressure wheel pulls the tape to the upper side of the front end of the fur-like fabric and presses the tape on the upper surface of the fur-like fabric, and the pressure wheel maintains the current position; Afterwards, the upper rubber roller and the lower rubber roller of the two material guide mechanisms rotate synchronously to continue to convey the imitation fur fabric forward. At the same time, the two positioning drive components drive the winding core shaft to rotate to wind the tape. The winding of the tape is consistent with the movement of the imitation fur fabric. Under the pulling force of the winding core shaft, the tape is continuously unwound and adhered to the upper surface of the imitation fur fabric. Step 5: The adhesive tape pulls the front end of the imitation fur fabric to the winding core shaft and wraps around the surface of the winding core shaft twice. After that, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms stop rotating synchronously, and the adhesive tape and the imitation fur fabric both maintain the current state; After the two longitudinal linear modules synchronously drive the support shaft to translate forward to the set position, they stop moving, the tape portion located on the lower side of the pinch wheel is separated from the surface of the imitation fur fabric and remains in a tensioned state, the cutting assembly cuts the tape, and then the cutting assembly is reset, and each pinch wheel remains in the current state; Afterwards, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms start to rotate synchronously, the imitation fur fabric continues to be wound on the winding core shaft, and the encoder of the rear side material guide mechanism continues to record the feeding length of the imitation fur fabric; Step 6: When the feeding length of the imitation fur fabric recorded by the encoder of the rear side material guide mechanism reaches the set value, the winding core shaft and the upper and lower rubber rollers of the two material guide mechanisms stop rotating synchronously, and then the transverse linear module 1 drives the cutting knife 1 to move transversely to cut the imitation fur fabric, and the cutting knife 1 returns to the initial position; Step 7: After the two longitudinal linear modules synchronously drive the support shaft to translate backward to the set position, each pressing wheel presses the tape onto the surface of the cut fur-like fabric and keeps the lower rubber roller of the front material guide mechanism pressed; Afterwards, the winding core shaft and the upper and lower rubber rollers of the front material guide mechanism start to rotate synchronously, and the cut imitation fur fabric continues to be transported forward and continues to be wound on the winding core shaft. During this process, the lower rubber roller of the front material guide mechanism drives each pressing wheel to rotate, pulling the corresponding adhesive tape to unwind, and the adhesive tape continues to be adhered to the surface of the cut imitation fur fabric; Step 8: When the tail end of the cut fur-like fabric leaves the front material guide mechanism, the two longitudinal linear modules synchronously drive the support shaft to translate forward, and at the same time, the second drive assembly drives each sealing support plate to rotate downward around the support shaft. During this process, the cut fur-like fabric continues to be wound on the winding core shaft, and the adhesive tape moves with the tail end of the cut fur-like fabric and remains in a tensioned state. The upper rubber roller and the lower rubber roller of the rear material guide mechanism start to rotate synchronously, and the imitation fur fabric continues to be conveyed forward and passes through the front material guide mechanism. When the length reaches ΔL, the two material guide mechanisms stop feeding; Step 9: The cut imitation fur fabric is wound on the winding core shaft to form a material roll, and the pressing wheel presses the tape on the surface of the material roll. After the tape is wound twice, the winding core shaft stops rotating; Afterwards, each sealing support plate swings backward around the support axis to a set angle value and then stops swinging, the cutting assembly cuts the tape, and then the cutting assembly resets to complete the roll sealing; Step 10: The second cylinder drives the middle and rear part of the unloading plate to rise upward, so that the unloading plate is close to the bottom of the material roll and maintains an inclined state with the front lower and the rear higher; Afterwards, the execution ends of the two positioning drive assemblies move synchronously away from each other and disengage from the two ends of the winding core shaft, and the material roll falls to the upper surface of the unloading plate and rolls forward to the conveyor belt assembly, which transports the sealed material roll to the storage area; Repeat the process from step 2 to step 10 to automatically cut and rewind the next roll.
