Description

Technical Field

[0001] This application relates to the field of fabric processing technology, and in particular to an automated fabric splicing device. Background Technology

[0002] In the field of fabric processing technology, fabrics include a variety of flexible materials such as cloth and film, and their application range is becoming increasingly wide, involving multiple fields such as clothing, home furnishing, industrial textiles and agriculture. Fabric processing involves many processes, among which fabric splicing is a key process link. It can combine fabrics of different specifications, materials and functions to meet diverse product design and usage needs.

[0003] In related technologies, semi-automatic fabric splicing equipment is commonly used. Semi-automatic splicing equipment uses tools such as robotic arms to complete some splicing steps. Operators need to manually align the edges of the fabric and adjust its position, while the robotic arms are responsible for performing welding along preset paths. Such equipment can achieve mechanization and standardization of some processes and is suitable for mass production scenarios.

[0004] However, the main limitation of existing technologies is the low level of automation, making it difficult to achieve full automation from fabric positioning and alignment to splicing. The manual involvement in some processes limits production efficiency and is prone to problems such as welding position deviation and uneven welding due to operational errors. Utility Model Content

[0005] To address the aforementioned issues, this application provides an automated fabric splicing device.

[0006] The automated fabric splicing device provided in this application adopts the following technical solution: An automated fabric splicing device includes a frame, two unwinding mechanisms, a welding mechanism, and an automatic traction mechanism. The two unwinding mechanisms, the welding mechanism, and the automatic traction mechanism are all mounted on the frame. Each unwinding mechanism includes an unwinding component and a conveying component. The fabric unwound by the unwinding component is conveyed by the conveying component. The conveying component conveys the fabric to the automatic traction mechanism for partial overlap. The automatic traction mechanism pulls the partially overlapped area to the welding mechanism for welding.

[0007] By adopting the above technical solution, two unwinding mechanisms unwind the fabric through the unwinding assembly, and the fabric is transported to the automatic traction mechanism through the conveying assembly. During the traction process, the two pieces of fabric partially overlap. The automatic traction mechanism accurately pulls the overlapping area to the welding mechanism to complete the welding of the two fabrics to form a large piece of fabric. The above process transforms the traditional positioning, alignment and welding processes that rely on manual intervention into a continuous automated process, which significantly reduces the efficiency fluctuations and operational errors caused by manual intervention. At the same time, continuous automated control improves the splicing accuracy and process stability, realizing fully automated production from fabric processing to finished fabric output.

[0008] Preferably, it further includes a folding mechanism, which includes at least one folding element disposed on the frame.

[0009] By adopting the above technical solution, when the fabric is pulled and conveyed by the automatic traction mechanism, the folding piece can fold the edges of the fabric inward from both sides simultaneously. After the folding action is completed, the automatic traction mechanism continues to pull the fabric with folded edges through the welding mechanism, and the welding mechanism welds the edges of both ends of the fabric.

[0010] Preferably, the conveying assembly includes two conveying rollers and a first drive unit. The two conveying rollers are rotatably supported on the frame, and the first drive unit drives one of the conveying rollers to slide horizontally.

[0011] By adopting the above technical solution, the conveyor roller drive can drive a single conveyor roller to slide in real time according to the change of fabric tension. When the fabric tension is high, the first drive unit pushes the conveyor roller closer to another conveyor roller, reducing the distance between the two conveyor rollers to increase the contact pressure and traction between the fabric and the conveyor roller, quickly tightening the fabric and restoring stable tension. When the fabric tension is detected to be too high, the first drive unit pulls the conveyor roller away from the other conveyor roller, widening the distance between the two conveyor rollers to reduce the contact pressure and traction, reducing excessive stretching or breakage of the fabric, and ensuring that the fabric is conveyed to the automatic traction mechanism in a flat and uniform state, further improving the automation adaptability and conveying reliability of the entire fabric splicing process.

[0012] Preferably, the unwinding assembly includes an unwinding roller and a second drive unit for the unwinding roller, the second drive unit including a first drive member that drives the unwinding roller to rotate.

[0013] By adopting the above technical solution, the drive component can directly drive the unwinding roller to rotate, thereby enabling the unwinding roller to rotate stably and unwind the fabric wound onto the unwinding roller, providing a foundation for the subsequent conveying components to transport the fabric.

[0014] Preferably, the second drive unit further includes two swing arms, which are rotatably supported on the frame and are respectively connected to both ends of the unwinding roller.

[0015] By adopting the above technical solution, when the fabric tension changes, the swing arms oscillate up and down. Since the two swing arms are fixedly connected to both ends of the unwinding roller, they further drive the unwinding roller to finely adjust its position in the vertical direction, thereby compensating for the impact of tension fluctuations on the unwinding process in real time. This design enables the unwinding roller to automatically adjust its height according to changes in fabric tension, maintaining a constant tension during fabric conveying and ensuring that the fabric is conveyed to the conveying assembly in a flat and uniform state, further improving the automation adaptability and conveying reliability of the entire fabric splicing process.

[0016] Preferably, the second drive unit further includes a second drive member for driving the swing arm member, the second drive member driving the swing arm member to swing.

[0017] By adopting the above technical solution, the second driving component can drive the swing arm component to swing back and forth in the vertical direction, which can realize the dynamic adjustment of the vertical position of the unwinding roller. When the fabric becomes loose or tight due to tension fluctuations during the unwinding process, the swing arm component drives the unwinding roller to adjust in the vertical direction, thereby adjusting the tension state of the fabric in real time.

[0018] Preferably, the unwinding assembly further includes a displacement unit, which drives the unwinding roller to slide horizontally, and the unwinding roller is disposed on the frame.

[0019] By adopting the above technical solution, the displacement unit drives the unwinding roller to slide laterally on the frame, realizing the dynamic adjustment of the lateral position of the unwinding roller. The lateral position of the unwinding roller can be adjusted in real time according to the fabric width, tension or process requirements, thereby adapting to the processing requirements of fabrics of different specifications.

[0020] Preferably, the automatic traction mechanism is disposed between the output end of the conveying component and the input end of the welding mechanism.

[0021] By adopting the above technical solution, the automatic traction mechanism can directly receive the fabric that has been output by the transmission component and has maintained a stable tension. The automatic traction mechanism pulls the fabric to overlap and inputs it into the welding mechanism for welding the overlapping area.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Two unwinding mechanisms work together with the unwinding and conveying components to output two pieces of fabric. During the traction process, the automatic traction mechanism achieves dynamic alignment and overlapping positioning of the two pieces of fabric, and accurately conveys the overlapping area to the welding mechanism to complete the sewing. This transforms the traditional manual positioning, alignment and welding process into a continuous automated process. It not only significantly reduces efficiency fluctuations and operational errors caused by manual intervention, but also improves splicing accuracy and process stability through dynamic tension adjustment and position feedback mechanisms, ultimately achieving fully automated production from raw material unwinding to finished product output. 2. The folding piece folds the fabric edges inward simultaneously from both sides to form a neat folded edge. Then, the automatic traction mechanism continuously pulls the processed fabric to the welding mechanism to complete the edge welding. 3. When insufficient fabric tension is detected, the drive unit actively pushes the conveyor roller on one side to move closer to the other side, reducing the distance between the two conveyor rollers to enhance contact pressure and traction, quickly tightening the fabric and restoring stable tension. When the tension is too high, the drive unit pulls the conveyor rollers in the opposite direction to separate them, widening the distance between the two conveyor rollers to reduce traction, reducing excessive stretching or breakage of the fabric, and ensuring that the fabric is stably conveyed to the automatic traction mechanism in a flat and uniform state, significantly improving the reliability and automation adaptability of the conveying process.

[0033] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0034] This application discloses an automated fabric splicing device. This automated fabric splicing device is used in the agricultural field. In agriculture, with the development of agricultural modernization, the demand for agricultural coverings is increasing. Agricultural fabrics and mulch films play an important role in agricultural planting, such as maintaining soil moisture and suppressing weed growth. By splicing fabrics to form large-size coverings, the needs of large-area agricultural coverage can be better met. This is of great significance for improving agricultural production efficiency and protecting the crop growth environment. In this embodiment, its function is to splice two small pieces of fabric into a single, continuous fabric.

[0035] Specifically, refer to Figure 1 The system includes a frame 1, two unwinding mechanisms, a welding mechanism, and an automatic traction mechanism. All three mechanisms are mounted on the frame 1. Each unwinding mechanism includes an unwinding assembly and a conveying assembly 3. The fabric unwound by the unwinding assembly is conveyed by the conveying assembly 3, which then transfers the fabric to the automatic traction mechanism for partial overlap. The automatic traction mechanism then pulls the partially overlapped area to the welding mechanism for welding. This demonstrates that the two unwinding mechanisms unwind the fabric via the unwinding assembly, and then convey the fabric to the automatic traction mechanism via the conveying assembly 3. During the traction process, the two pieces of fabric partially overlap. The automatic traction mechanism continuously pulls the overlapping area to the welding mechanism to complete the welding of the two fabrics into a single large piece of fabric. The above process transforms the traditional positioning, alignment, and welding processes that rely on manual intervention into a continuous automated process, significantly reducing efficiency fluctuations and operational errors caused by manual intervention. At the same time, continuous automated control improves splicing accuracy and process stability, realizing fully automated production from fabric processing to finished fabric output.

[0036] Correspondingly, the frame 1 includes a first frame 11 and a second frame 12. There is one first frame 11 and two second frames 12. The two second frames 12 are located at both ends of the first frame 11 and are staggered in the horizontal direction. Both the first frame 11 and the second frame 12 are hollow frame structures, and the two second frames 12 correspond one-to-one with the unwinding mechanism.

[0037] Reference Figure 2 Specifically, the unwinding assembly includes an unwinding roller 21 and a second drive unit 22 for the unwinding roller 21. The unwinding roller 21 is rotatably supported on the second frame 12. (Refer to...) Figure 7 The second drive unit 22 includes a first drive member 221, a first gear 222, and a second gear 223. The first gear 222 is coaxially fixed with the output shaft of the first drive member 221. The unwinding roller 21 has toothed sections 211 at both ends. The two ends of the second gear 223 mesh with the first gear 222 and the toothed sections 211, respectively. The function of the second gear 223 is to transmit the power of the first drive member 221 to the unwinding roller 21, so that the unwinding roller 21 can rotate to perform the unwinding operation.

[0038] It should be noted that in this embodiment, the first driving component 221 is set as a magnetic powder brake. Due to the large mass of the fabric, the large mass of the fabric will generate significant inertial force due to inertia when rotating, which may cause the fabric to loosen, break or the equipment to vibrate during the unwinding process. Therefore, it is necessary to provide precise braking torque and dynamic tension control through the magnetic powder brake. The magnetic powder brake controls the torque output by adjusting the excitation current, which can absorb the kinetic energy generated by the inertial force of the fabric in real time, reduce the mechanical impact caused by sudden start-stop or speed change, and maintain constant tension during the unwinding process of the fabric, reduce the occurrence of material deformation or wrinkles, thereby ensuring the stability and continuity of the subsequent splicing process.

[0039] Furthermore, the second drive unit 22 also includes two swing arms 224 and a second drive unit 225 for the swing arms 224. In this embodiment, the second drive unit 225 is configured as a drive cylinder. The unwinding roller 21 is rotatably supported on the swing arms 224, and the end of the swing arms 224 away from the unwinding roller 21 is rotatably supported on the second frame 12.

[0040] Meanwhile, the piston rod of the drive cylinder is vertically downward, and the drive cylinder is fixed to the middle of the swing arm 224. The piston rod of the drive cylinder is fixed to the first frame 11. The drive cylinder controls the swing of the swing arm 224 by extending and retracting the piston rod. Through the action of the drive cylinder, the angle of the swing arm 224 can be flexibly adjusted according to actual production needs, thereby adjusting the vertical position of the unwinding roller 21, and further adjusting the unwinding angle and position of the unwinding roller 21. Specifically, when the piston rod of the drive cylinder extends or retracts, the swing arm 224 rotates and is supported on the second frame 12, and the swing arm 224 is fixedly connected to the piston rod of the drive cylinder. The end of the piston rod of the drive cylinder is connected to the first frame 11. The extension or retraction of the piston rod of the drive cylinder causes the swing arm 224 to rotate around the pivot point. When the piston rod of the drive cylinder extends, the unloading swing arm swings upward and the unwinding roller 21 moves upward. When the piston rod of the drive cylinder retracts, the unloading swing arm swings downward and the unwinding roller 21 moves downward. Thus, the angle and position of the unwinding roller 21 are automatically adjusted according to the thickness and tension requirements of the fabric material.

[0041] Reference Figure 3 Meanwhile, the unwinding assembly also includes a displacement unit 23, which includes a slide rail 231, a sliding seat 232, and a third driving member 233. In this embodiment, the third driving member 233 is also configured as a driving cylinder. The slide rail 231 is fixedly disposed on the upper surface of the first frame 11, the sliding seat 232 is fixedly disposed on the lower surface of the second frame 12, and the sliding seat 232 is slidably disposed on the slide rail 231. The third driving member 233 is disposed on one side of the first frame 11, the driving cylinder is fixed on the first frame 11, and the piston rod of the driving cylinder is fixed on the second frame 12.

[0042] This demonstrates that the sliding engagement between the slide rail 231 and the sliding seat 232 allows the second frame 12 to slide freely along the slide rail 231, further enabling the unwinding roller 21 to achieve lateral displacement. When the piston rod of the drive cylinder extends or retracts, it directly pushes or pulls back the second frame 12 to move along the slide rail 231, thereby driving the unwinding roller 21 to adjust its position synchronously. This allows it to adapt to the unwinding tension requirements of different fabric specifications according to the thickness, width, or tension requirements of the fabric, reducing the problem of stretching deformation or breakage caused by differences in material specifications.

[0043] Reference Figure 4 and Figure 5 Furthermore, the conveying assembly 3 includes two conveying rollers 31 and a first drive unit 32 for the conveying rollers 31. The first drive unit 32 includes a support frame 321, a fourth drive member 322, and a bearing seat 323. The support frame 321 is fixedly connected to the second frame 12. The bearing seat 323 is disposed at both ends of the two conveying rollers 31. One conveying roller 31 is rotatably supported on the frame 1, and the other conveying roller 31 is rotatably supported on the bearing seat 323. In this embodiment, the fourth drive member 322 is also configured as a drive cylinder. The piston rod of the drive cylinder is fixedly connected to the bearing seat 323, and the bearing seat 323 is slidably disposed on the support frame 321.

[0044] This explains that the piston rod of the drive cylinder pushes the bearing seat 323 to further adjust the distance between the two conveying rollers 31. The conveying can be carried out according to the width and thickness difference of the fabric material or the tension of the fabric during conveying. When the fabric is wider, the distance between the two conveying rollers 31 is increased to adapt to the material tension requirements. When the fabric is narrower, the distance between the two conveying rollers 31 is decreased to reduce the occurrence of fabric deviation or wrinkles.

[0045] Furthermore, an automatic traction mechanism is set at the output end of the conveying component 3 and the input end of the welding mechanism. The welding mechanism is set on the first frame 11. The automatic traction mechanism includes several traction rollers 5. Some traction rollers 5 are rotatably supported on the second frame 12, and some traction rollers 5 are rotatably supported on the lower end of the welding mechanism. The traction rollers 5 rotatably supported on the lower end of the welding mechanism are staggered. The welding mechanism and several traction rollers 5 are distributed in the vertical direction. Several traction rollers 5 pull the fabric to the welding mechanism.

[0046] Furthermore, two unwinding mechanisms are respectively located at both ends of the first frame 11 and are staggered in the horizontal direction. The discharge direction of the left unwinding mechanism extends from left to right, and the discharge direction of the right unwinding mechanism extends from right to left. When the two fabrics are guided into the automatic traction mechanism by the conveying assembly 3, due to the vertical distribution of the traction rollers 5 that are rotated and supported at the lower end of the welding mechanism and the staggered arrangement of the traction rollers 5 that are rotated and supported at the lower end of the welding mechanism, the two fabrics gradually form a partially overlapping area after horizontally intersecting. Then, they are continuously conveyed vertically by the traction rollers 5 group to the bottom of the hot press welding head of the welding mechanism to complete the welding of the overlapping area of ​​the fabric.

[0047] Reference Figure 6 and Figure 8 In addition, it also includes a folding mechanism, which includes at least one folding piece 6. In this embodiment, there are two folding pieces 6, which are disposed at both ends of the first frame 11. In this embodiment, the folding piece 6 is V-shaped.

[0048] This explains that when the fabric passes through the conveying component 3 and the automatic traction mechanism, the V-shaped frame forms a lateral limit on the edge of the fabric, ensuring that the edge of the fabric is always constrained within the V-shaped frame during the movement. The geometry of the V-shaped frame applies a guiding force to the edge, causing the edge of the fabric to fold inward, preparing for subsequent welding.

[0049] Furthermore, the welding mechanism includes three welding devices 4, which are located at both ends and the middle of the first frame 11. The welding device 4 located in the middle is used to press the overlapping interface of the two fabric pieces, while the two ultrasonic pressers located at both ends of the first frame 11 are used to press the folded position of the edge folding piece 6 after folding the edges of the two fabric pieces. In this embodiment, the welding device 4 is set as an ultrasonic presser. The working principle of the ultrasonic presser is to use the energy of ultrasonic waves to generate heat at the contact point of the fabric, thereby achieving pressing.

[0050] Reference Figure 9 This illustrates that during the conveying process of the fabric through the conveying component 3 and the automatic traction mechanism, the V-shaped frame has stably constrained the fabric edge within the V-shaped frame through the lateral limiting effect, and has successfully caused the fabric edge to fold inward by applying guiding force to the edge with its own geometry. When the fabric with the edge initially folded enters the working range of the welding mechanism, the welding operation is completed by three welding devices 4, which are set as ultrasonic pressers. The ultrasonic presser located in the middle of the first frame 11 first presses the overlapping interface of the two fabric pieces. At the same time, the two ultrasonic pressers located at both ends of the first frame 11 simultaneously press the folded position of the two fabric edges after being folded by the folding edge piece 6.

[0051] The implementation principle of the automated fabric splicing device in this application embodiment is as follows: Before the device is started, the swing arm 224 is controlled to swing according to the specifications of the fabric to be spliced ​​by the second drive component 225 to adjust the vertical position of the unwinding roller 21. At the same time, the second frame 12 is pushed to slide along the slide rail 231 by the third drive component 233 to adjust the lateral position of the unwinding roller 21 to ensure that the unwinding tension is adapted to the fabric characteristics.

[0052] The first drive unit 221 is activated. The first drive unit 221 drives the unwinding roller 21 to rotate through the first gear 222 and the second gear 223, so as to smoothly unwind the fabric. The first drive unit 221 is set as a magnetic powder brake. The magnetic powder brake adjusts the torque in real time, absorbs the inertial force of the fabric, maintains the constant tension of the fabric during the unwinding process, and avoids loosening, breakage or wrinkling.

[0053] After unwinding, the fabric enters the conveying assembly 3. The fourth drive unit 322 pushes the bearing seat 323 to slide along the support frame 321, adjusting the distance between the two conveying rollers 31. The distance is increased when facing a wider fabric and decreased when facing a narrower fabric, ensuring that the fabric is conveyed smoothly to the automatic traction mechanism with reduced deviation and wrinkles.

[0054] Among the several traction rollers 5, some traction rollers 5 are supported on the second frame 12, and some traction rollers 5 are supported on the lower end of the welding mechanism. These traction rollers 5 operate synchronously, pulling the fabric from the two unwinding mechanisms to the designated area, so that the two pieces of fabric partially overlap.

[0055] During the traction process, the V-shaped folding pieces 6 at both ends of the first frame 11 laterally limit the edges of the fabric. The V-shaped geometric structure applies guiding force to the edges of the fabric, causing the edges of the two pieces of fabric to fold inward respectively, in preparation for subsequent welding.

[0056] The automatic traction mechanism pulls the two pieces of fabric to overlap. The overlapping area and the edge after folding are continuously pulled to the welding mechanism installed on the first frame 11. The three welding devices 4 of the welding mechanism work synchronously. The welding device 4 in the middle presses the overlapping interface of the two pieces of fabric, and the welding devices 4 at both ends press the edge after folding of the two pieces of fabric respectively. Ultrasonic energy is used to generate heat at the contact point of the fabric to achieve a stable pressing.

[0057] After pressing, a large piece of fabric is formed. The entire process is fully automated, from unwinding and splicing the fabric to outputting the finished product.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
