Description

Technical Field

[0001] This invention relates to the field of automatic fabric stretching and edge alignment technology using rollers, and in particular to a roller-type fully automatic fabric stretching and edge alignment device that replaces manual labor. Background Technology

[0002] In the textile printing and dyeing finishing industry, tenter frame setting is a key process to ensure the stability of fabric width and the smoothness of the fabric surface. The fabric feeding stage of traditional tenter frames is highly dependent on manual operation. Operators need to manually unfold the wrinkled fabric and continuously adjust it to align the fabric edges before it can enter the setting area.

[0003] This manual method has significant drawbacks: First, it is extremely labor-intensive and inefficient, making it difficult to match the pace of modern high-speed production lines; second, the accuracy of manual edge alignment is unstable, easily leading to problems such as "wrinkled edges" and fabric slippage, resulting in quality defects such as uneven fabric width and skewed fabric after shaping, making it difficult to guarantee product qualification rates; third, operators' hands are in close proximity to the high-speed moving fabric for extended periods, posing serious safety hazards. Therefore, the industry urgently needs a technical solution that can achieve fully automated, high-precision fabric stretching and edge alignment to completely replace manual labor, thereby improving quality, efficiency, and safe production. We propose a roller-type fully automated fabric stretching and edge alignment device to replace manual labor. Summary of the Invention

A power supply end is rotatably installed inside the second side end. The main frame tube is equipped with a power supply frame, a connecting terminal, an electric slide, and a second electric push rod. The side of the main frame tube is circumferentially arrayed with equally spaced slots. The slots are equipped with a slider, a connecting rod, a detection block, a silicone strip, and a support plate.

[0006] Furthermore, the fixed frames are vertically fixedly installed on the base frame in pairs symmetrically. The first adjusting rod is rotatably installed in the lower position inside the mounting cavity. The worm gear is fixedly sleeved on the side of the first adjusting rod and is movably disposed inside the fixed frame. The worm wheel is engaged on the side of the worm gear and is rotatably disposed inside the fixed frame. The linkage rod is disposed between the fixed frames of the corresponding opening roller and the stretching mechanism, and both ends of the linkage rod extend through into the inside of the fixed frame. The worm wheel is limited and sleeved on the side of the linkage rod.

[0007] Furthermore, the lower end of the second adjusting rod corresponds to the upper end of the first adjusting rod, the second adjusting block is threaded onto the side of the second adjusting rod and the second adjusting block is attached to the wall of the mounting cavity, the constraint rod is symmetrically fixedly installed on the upper side of the second adjusting block and extends out through the upper side of the fixed frame, the movable plate is set on the upper side of the fixed frame, and the opening roller and the stretching mechanism are installed on the upper side of the movable plate.

[0008] Furthermore, a slot is provided on the lower side of the second adjusting rod. The slot is a regular hexagonal groove. The first electric push rod is fixedly installed on the upper side of the first adjusting rod. The first electric push rod is powered by a built-in power supply. A locking block is fixedly installed on the upper side of the first electric push rod. The locking block is a regular hexagonal block.

[0009] Furthermore, the first adjusting block is threaded onto the side of the first adjusting rod and is slidably installed inside the slide groove. The mating groove corresponds to the support groove position. The mounting bracket is set between the fixed brackets and is parallel to the base frame. The mating block is slidably installed at both ends of the mounting bracket and is slidably installed inside the support groove.

[0010] Furthermore, the first side end is fixedly installed inside the main frame tube and rotated and fixed to the upper side of the movable plate by a bearing. The second side end is fixedly installed inside the main frame tube. The power supply end is fixed to the upper side of the movable plate by a supporting ring frame. A conductive slip ring is provided on the side of the power supply end.

[0011] Furthermore, the grooved wall has a connecting groove, and limit blocks are fixedly installed on both sides of the grooved wall. The power supply frame is fixedly installed on the side of the first side end, the connecting terminal is fixedly installed on the side of the power supply frame and is slidably installed inside the conductive slip ring of the power supply end, the electric slide table is symmetrically fixedly installed on the side of the power supply frame, the slider is slidably installed inside the groove, the connecting rod is fixedly connected between the slider and the side of the electric slide table slide and is slidably installed inside the connecting groove, the detection block is fixedly installed on the side of the connecting rod, and the silicone strip is fixedly connected between the sides of the detection block and is partially slidably installed inside the groove.

[0012] Furthermore, the second electric actuator is fixedly installed at the center of the side of the power supply frame, and the support plate is fixedly installed at the output end of the second electric actuator and is located inside the slot and attached to the lower side of the silicone strip.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves fully automatic high-precision edge alignment by setting up a stretching mechanism, thereby improving product quality. Specifically, the infrared detection block on the stretching mechanism monitors the fabric edge position in real time and feeds the signal back to the PLC controller, which drives the electric slide table to precisely adjust the position of the silicone strip and the fabric. This process is closed-loop controlled, and the edge alignment accuracy can reach the millimeter level. This effectively avoids the randomness of manual operation and fundamentally eliminates quality problems such as fabric skewing and uneven width, ensuring the uniformity and stability of the shaping effect.

[0014] 2. By setting up a spreading roller, this invention can improve production efficiency and equipment automation. Specifically, the synergistic effect of the automatic spreading roller and the stretching mechanism allows the fabric to be spread out and centered quickly and smoothly, allowing the tenter frame to run at a higher speed. This breaks the limitation on the overall line speed caused by the efficiency bottleneck of manual operation. When running in full automation, no manual intervention is required, which significantly improves the production capacity per unit time.

[0015] 3. This invention achieves dynamic tension adjustment by setting a second electric actuator, a support plate, and their surrounding components, thereby improving applicability. Specifically, by controlling the support plate through the second electric actuator, the shape of the silicone strip can be changed in real time, thus fine-tuning its tension on the fabric. This dynamic adjustment capability allows the device to adapt to fabrics of different weights, materials, and elasticities, ensuring a wrinkle-free, smooth, and flat effect under various working conditions, thus broadening the application range of the equipment.

[0016] 4. This invention features an adjustable and modular support mechanism. The support mechanism can not only adjust the height of the fixed roller by raising and lowering the movable plate, but also conveniently add opening rollers and stretching mechanisms through the ingenious design of the mounting frame and mating blocks. The modular design allows users to flexibly configure the number and layout of rollers according to the process requirements of different products, realizing multiple uses of one machine and greatly enhancing the adaptability and flexibility of the production line.

[0017] 5. The device of this invention replaces the original manual spreading and edge-aligning positions, freeing operators from high-intensity, repetitive physical labor, while completely avoiding the risk of hands getting caught in the equipment, achieving inherent safety, and reducing the labor intensity and safety hazards of manual labor.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figure 1 and Figure 2As shown, a roller-type fully automatic fabric stretching and edge-aligning device that replaces manual labor includes a base frame 1, which is a rectangular frame. A support mechanism 2 is provided on the upper side of the base frame 1. The support mechanism 2 can realize synchronous lifting and adjustment. An opening roller 3 and a stretching mechanism 4 are provided on the upper side of the support mechanism 2. The opening roller 3 is an existing mature structure. When its roller shaft rotates, the side expansion plate can make cyclic reciprocating lateral movements, which can stretch and unfold the fabric. The stretching mechanism 4 can further stretch and center the stretched fabric, so that the fabric will move smoothly along a given path. The stretching mechanism 4 can also adjust the tension of the fabric as needed to maintain the fabric in a uniform, centered, and wrinkle-free state. In addition, the support mechanism 2 can easily increase the number of opening rollers 3 and stretching mechanisms 4, and the position of all rollers can be easily adjusted.

[0022] like Figures 2 to 5As shown, the support mechanism 2 includes four sets of fixed frames 21. The fixed frames 21 are symmetrically and vertically fixed to the base frame 1 in pairs. Each fixed frame 21 is a rectangular frame. An installation cavity 22 is provided on the upper side of each fixed frame 21. The installation cavity 22 is a cylindrical cavity with an I-shaped cross-section. A first adjusting rod 24 is rotatably installed inside the lower part of the installation cavity 22. The first adjusting rod 24 is a cylindrical threaded rod. A worm gear 25 is fixedly sleeved on the side of the first adjusting rod 24 and is movably disposed inside the fixed frame 21. A worm wheel 251 is meshed on the side of the worm gear 25 and is rotatably disposed inside the fixed frame 21. Between the fixed frames 21 corresponding to the opening roller 3 and the stretching mechanism 4... A linkage rod 252 is provided, with both ends of the linkage rod 252 extending through into the interior of the fixing frame 21. A worm gear 251 is fitted onto the side of the linkage rod 252 for limiting. A second adjusting rod 26 is provided at an upper position inside the mounting cavity 22, with the lower end of the second adjusting rod 26 corresponding to the upper end of the first adjusting rod 24. The second adjusting rod 26 is a cylindrical threaded rod with a cross-shaped cross section. A second adjusting block 261 is threadedly fitted onto the side of the second adjusting rod 26, and the second adjusting block 261 fits against the wall of the mounting cavity 22. The second adjusting block 261 is a circular block with threads on its inner side. A constraint rod 262 is symmetrically fixedly installed on the upper side of the second adjusting block 261, and the constraint rod 262 passes through the fixing frame 21. Extending from the upper side, a movable plate 263 is fixedly installed on the upper side of the constraint rod 262, and the movable plate 263 is positioned on the upper side of the fixed frame 21. The opening roller 3 and the stretching mechanism 4 can be installed on the upper side of the movable plate 263. A slot 27 is provided on the lower side of the second adjusting rod 26. The slot 27 is a regular hexagonal slot. A first electric push rod 271 is fixedly installed through the upper side of the first adjusting rod 24. The first electric push rod 271 is powered by an internal power supply or an external line. A locking block 272 is fixedly installed on the upper side of the first electric push rod 271. The locking block 272 is a regular hexagonal block. Specifically, the corresponding worm gear 251 can be synchronously driven to rotate through the linkage rod 252. 51 rotates and engages with the worm gear 25, causing the worm gear 25 to drive the first adjusting rod 24 to rotate. At this time, the first electric actuator 271 pushes the locking block 272 upward and locks it into the slot 27, so that the first adjusting rod 24 and the second adjusting rod 26 are linked. In this way, when the first adjusting rod 24 rotates, it can synchronously drive the second adjusting rod 26 to rotate. The second adjusting block 261 engages with the second adjusting rod 26, and the synchronous constraint rod 262 is constrained to slide, so that the second adjusting block 261 can perform lifting and lowering operations. The constraint rod 262 can drive the movable plate 263 to lift and lower. The opening roller 3 and the stretching mechanism 4 installed on the side of the movable plate 263 can be adjusted in height. The wall of the mounting cavity 22 is provided with a sliding groove 23 that passes through the fixing bracket 21, corresponding to the position of the first adjusting rod 24. The sliding groove 23 is a rectangular groove. Support grooves 231 that pass through the fixing bracket 21 are symmetrically provided at equal intervals on the wall of the sliding groove 23. The support grooves 231 are also rectangular grooves. A first adjusting block 241 is threaded onto the side of the first adjusting rod 24 and slidably installed inside the sliding groove 23. The first adjusting block 241 is a convex annular block with threads on its inner side. A mating groove 242 is provided, corresponding to the support groove 231. A mounting frame 28 is provided between the fixing frames 21, and the mounting frame 28 is arranged parallel to the base frame 1. The mounting frame 28 is an I-shaped plate. A mating block 281 is slidably installed at both ends of the mounting frame 28 and is slidably disposed inside the support groove 231. The mating block 281 is a "C" shaped block. Specifically, during installation, the mounting frame 28 is first placed between the two sets of fixing frames 21, and then the mating block 281 is partially inserted into the mounting frame. The slide rail on the side of the mounting bracket 28 ensures that the protrusion on one side of the mounting bracket 28 is embedded in the mating groove 242 of the first adjusting block 241, while the protrusion on the other side fits against the side of the fixing bracket 21. At this time, the first electric push rod 271 pulls the locking block 272 out of the locking groove 27, and the worm gear 25 only drives the first adjusting rod 24 to rotate. The first adjusting block 241 can then be engaged by the thread of the first adjusting rod 24, and the first adjusting block 241 can slide synchronously in the slide groove 23 to raise and lower. The raising and lowering movement of the first adjusting block 241 is controlled by the mating groove 241. The mating block 281 drives the entire mounting frame 28 to rise and fall. During this adjustment process, the mating block 281 is not inserted into the support groove 231, so the first adjusting block 241 can slide freely in the slide groove 23 without affecting the rise and fall of the mounting frame 28. After the position of the mounting frame 28 is adjusted, the mating block 281 is completely pushed into the support groove 231, so that the mounting frame 28 can be limited and supported by the mating block 281. In this way, a new opening roller 3 and a stretching mechanism 4 can be installed on the upper side of the mounting frame 28 for use.

[0023] like Figure 2 and Figures 6 to 10As shown, the stretching mechanism 4 includes a main frame tube 41, which is a hollow cylindrical tube. A first side end 43 and a second side end 44 are respectively provided at both ends of the main frame tube 41. The first side end 43 is fixedly installed inside the main frame tube 41 and is a U-shaped cylindrical shaft, rotatably fixed to the upper side of the movable plate 263 via bearings. The second side end 44 is fixedly installed inside the main frame tube 41 and is an L-shaped ring frame. A power supply end 4 is rotatably installed inside the second side end 44. 41. The power supply end 441 is fixed to the upper side of the movable plate 263 by a supporting ring frame. The power supply end 441 is a convex frame. A conductive slip ring is opened on the side of the power supply end 441 and connected to an external line. The power supply end 441 can continuously supply power to the subsequent components. Specifically, the end of the first side end 43 can be connected to an external drive motor. The motor can drive the first side end 43 to rotate, and the main frame cylinder 41 and the second side end 44 can rotate synchronously. The power supply end 441 rotates inside the second side end 44 and remains stationary. The main frame cylinder 41 has slots 42 arranged in a circumferential array at equal intervals on its side. A connecting groove 421 penetrating the main frame cylinder 41 to its inner side is formed on the wall of the slots 42. Limiting blocks 422 are fixedly installed on both sides of the wall of the slots 42. The limiting blocks 422 can be fixed by threads or snap-fit ​​to constrain and limit the components inside the slots 42. A power supply frame 45 is fixedly installed in a circumferential array at equal intervals on the side of the main frame cylinder 41 corresponding to the first side end 43. The power supply frame 45 is a rectangular frame with multiple power supply terminals on its side. A connecting terminal 451 is fixedly installed on the side of the power supply frame 45 away from the first side end 43. Terminal 451 is slidably installed inside the conductive slip ring of power supply terminal 441. Terminal 451 is connected to the internal circuit of power supply frame 45. Through continuous sliding electrical connection between terminal 451 and power supply terminal 441, power supply terminal 441 can continuously supply power to power supply frame 45. Power supply frame 45 is a convex cylindrical contact block. A sliding block 46 is symmetrically fixed on the side of power supply frame 45 near the main frame cylinder 41, and the sliding block 46 is electrically connected to the sub-contact of power supply terminal 441 of power supply frame 45. A slider 461 is slidably installed inside the slot 42 corresponding to the position of the sliding block 46. A connecting rod is fixedly connected between the slider 461 and the side of the sliding block 46. The connecting rod 462 is slidably disposed inside the connecting groove 421. A detection block 47 is fixedly disposed on the side of the connecting rod 462 away from the electric slide table 46. The detection block 47 is an infrared light sensor (which can detect the side position of the fabric in real time). A silicone strip 471 is fixedly connected between the sides of the detection block 47, and part of the silicone strip 471 is slidably installed inside the groove 42. Specifically, after the fabric is stretched by the spreading roller 3, it passes the side position of the main frame cylinder 41. First, the detection block 47 detects the side position of the fabric, and simultaneously the electric slide table 46 drives the connecting rod 462 to drive the slider 461 to slide inside the groove 42. After the detection block 47 is moved by the 462, the stretched silicone strip 471 will support the fabric to stretch and retract together. With the help of the external controller to control its stretching degree and frequency, it can be ensured that the fabric is kept evenly centered and wrinkle-free during the stretching process. The first side end 43 is driven to rotate by the drive end, which drives the main frame cylinder 41 and the second side end 44 to rotate. The synchronous power supply frame 45 can rotate with the first side end 43. The connecting terminal 451 slides in cooperation with the conductive slip ring of the power supply end 441. The power supply end 441, the connecting terminal 451 and the power supply frame 45 form a power supply system, which can continuously supply power to the electric slide table 46. A second electric push rod 48 is fixedly installed at the center of the side of the power supply frame 45 and is electrically connected to the sub-contact of the power supply terminal 441 of the power supply frame 45. A support plate 481 is fixedly installed at the output end of the second electric push rod 48 and is located inside the slot 42 and is attached to the lower side of the silicone strip 471. The support plate 481 is a rectangular plate. Specifically, by pushing and pulling the support plate 481 with the second electric push rod 48, the support plate 481 can push and pull the silicone strip 471 to deform it. In this way, the tension of the fabric on the side of the silicone strip 471 can be electrically controlled to further ensure that the fabric is evenly centered and wrinkle-free.

[0024] Working principle: Before use: First, fix the roller adjustment position. Fix the required opening roller 3 and stretching mechanism 4 to the side of the movable plate 263 on the upper side of the two fixed frames 21. At this time, the first electric push rod 271 pushes the locking block 272 to engage in the slot 27, driving the corresponding linkage rod 252 to rotate. This will drive the corresponding worm gear 251 to rotate and mesh with the worm 25. The worm 25 drives the first adjusting rod 24 to rotate. The second adjusting rod 26 moves synchronously with the first adjusting rod 24. At this time, the second adjusting block 261 is threaded on the side of the second adjusting rod 26. The constraint rod 262 is constrained and slides. The second adjusting block 261 can then lift and lower the movable plate 263. In this way, the required opening roller 3 and stretching mechanism 4 can be adjusted by lifting and lowering. The second step involves coordinating the roller layout. When a new opening roller 3 and stretching mechanism 4 need to be added, the corresponding mounting bracket 28 is positioned between the fixed brackets 21. At this time, the mounting bracket 28 has mating blocks 281 inserted into both sides, allowing the new opening roller 3 and stretching mechanism 4 to be fixedly positioned on the upper side of the mounting bracket 28. One protrusion of the mating block 281 is inserted into the mating groove 242, while the other protrusion of the mating block 281 is attached to the side of the fixed bracket 21. The first electric push rod 271 pulls the locking block 272 out of the groove 27, causing the first adjusting rod 24 to rotate independently. The first adjusting block 241 engages with the threaded side of the first adjusting rod 24, and the first adjusting block... The first adjusting block 241 can slide inside the slide groove 23 to move up and down. The first adjusting block 241 drives the entire mounting frame 28 to move up and down to adjust its position through the constraint mating block 281. After the position is adjusted, the mating block 281 is fully inserted into the side of the mounting frame 28. The protrusions on both sides of the mating block 281 are inserted into the support groove 231, thus supporting and constraining the mounting frame 28. At this time, the first adjusting block 241 slides inside the slide groove 23, passing through the inside of the mating block 281 without being interfered with. Similarly, by adding the mounting frame 28, new opening rollers 3 and stretching mechanisms 4 can be added for use. After installation, the position can be adjusted according to the needs to meet the diversity of on-site production. The third step is to lay and install the fabric. After the fabric is laid through the sides of the opening roller 3 and the stretching mechanism 4, one end of the fabric is fixed to the side of the take-up roller and it can be used. At the same time, the opening roller 3 and the stretching mechanism 4 can move slowly. With the help of manual labor, the fabric can be stretched and extended to facilitate the installation of the fabric. In use: First step, the fabric is automatically stretched and the equipment enters fully automatic operation. When the fabric passes the side of the stretching roller 3, the fabric drives the stretching roller 3 to rotate passively. At this time, the stretching plate on the side of the stretching roller 3 moves horizontally in a cyclical manner, which can stretch and unfold the fabric, so that the fabric is automatically unfolded. The second step is to center and stretch the fabric. When the fabric passes the side of the stretching mechanism 4, the detection block 47 performs infrared detection on the side of the fabric to drive its position. The external controller controls the electric slide table 46 to run, so that the slider 461 slides back and forth inside the slot 42, which drives the detection block 47 to stretch and retract the silicone strip 471. When the main frame cylinder 41 is rotated by the first side end 43, the silicone strip 471 moves laterally in a cyclic manner on the side of the first side end 43, which makes the fabric move smoothly along the given path, further stretching the fabric and keeping the fabric continuously and evenly centered and wrinkle-free. The third step involves dynamically adjusting the tension of the fabric. The fabric is stretched and extended by the opening roller 3, and then stretched and evenly centered by the stretching mechanism 4. Simultaneously, the second electric push rod 48 can push and pull the support plate 481, causing the support plate 481 to push the silicone strip 471 to deform. This changes the tension of the silicone strip 471 on the fabric, further ensuring even centering and a wrinkle-free state. All the above electrical control components are controlled by a PLC control system, which also monitors and adjusts the operating status of the equipment in real time.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
