Description

Technical Field

[0001] This utility model relates to the field of woven tape correction, specifically a woven tape correction device. Background Technology

[0002] Woven tapes (such as webbing, label tapes, and packaging tapes) are key flexible materials in industrial production, widely used in clothing accessories, electronic tags, packaging sealing, and automotive interiors. During production and processing, woven tapes are prone to lateral deviation due to factors such as material properties and equipment precision. Material properties cause some woven tapes (such as nylon and spandex blends) to undergo elastic deformation due to tension changes during high-speed transport, leading to lateral contraction or expansion of the tape. Equipment and process factors, such as uneven tension control during unwinding and rewinding, can cause the tape to become slack or taut, thus deviating from its track.

[0003] With the widespread adoption of automated production lines, woven tapes require precise conveying, positioning, and processing (such as heat transfer, punching, and bonding) at high speeds. For example, in electronic tag production, woven tapes must pass through the printing module at speeds of hundreds of meters per minute, with lateral offset controlled within ±0.1mm; otherwise, it can lead to pattern misalignment, barcode failure, or functional defects. Furthermore, in the high-end garment accessories sector, the edge neatness of the woven tape directly affects the product's aesthetics, while misalignment of packaging sealing tape can cause seal failure or packaging damage. Therefore, woven tape correction technology is a core element in ensuring both production efficiency and product quality.

[0004] For example, the Chinese authorized patent CN 206141018 U (Cotton Webbing Correction Device for Hot Plate Section of Double-Sided Machine) includes a correction roller, a manual adjustment bracket, and an automatic correction seat. The automatic correction seat has a connecting part in the middle, which is fixed to two parallel guide rails by air-cushion cylinders at both ends. An automatic adjustment valve is provided on the outward-facing side of each air-cushion cylinder. One end of the correction roller is connected to the manual adjustment bracket, and the other end is connected to the connecting part on the automatic correction seat. The cotton webbing correction device for the hot plate section of a double-sided machine provided by this utility model, by having an automatic adjustment valve, allows for left and right adjustment of the correction roller to effectively control the left and right deviation of the cotton webbing.

[0005] Although the aforementioned existing technology has the function of correcting the cotton webbing, it is difficult to control the correction range by adjusting the position of the correction rollers left and right. It is easy to have insufficient or excessive correction distance, and it is also easy to cause uneven tension at both ends of the conveyor line. Utility Model Content

[0006] The purpose of this utility model is to provide a weaving belt correction device to solve the problems mentioned in the background art, such as the difficulty in controlling the correction amplitude when adjusting the position of the correction rollers left and right, the easy insufficiency or excessive correction distance, and the easy uneven tension at both ends of the conveyor line.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a woven tape correction device, comprising a support frame, of which there are two. A first support frame is fixed to the upper middle of the support frame by screws. An intermediate correction roller is connected between the two first support frames. A rectangular through-slot is formed on both sides of the outer side of the intermediate correction roller from top to bottom. A limiting sliding groove is formed inside the intermediate correction roller along the direction of the rectangular through-slot. A correction component is provided outside the intermediate correction roller. The correction component includes an outer sliding ring, a rectangular sliding plate, and an intermediate connecting plate. The outer sliding ring is slidably connected to the outside of the intermediate correction roller. The rectangular sliding plate is fixed inside the outer sliding ring. The intermediate connecting plate is located in the middle position of the rectangular sliding plate. The rectangular sliding plate and the intermediate connecting plate slide within the rectangular through-slot and the limiting sliding groove. A woven tape body is pulled outside the correction component.

[0008] Preferably, a first pressure roller and a second pressure roller are rotatably connected between the two outer sliding rings along the outside of the intermediate correction roller via bearings. The first pressure roller and the second pressure roller are alternately arranged, and the number of first pressure rollers is one more than the number of second pressure rollers. The main body of the woven belt passes around the inside of the first pressure roller and exits from the second pressure roller. The main body of the woven belt is wavy outside the multiple first pressure rollers and second pressure rollers.

[0009] Preferably, the intermediate correction roller is rotatably connected to a drive intermediate shaft, and a threaded part is fixed outside the drive intermediate shaft within the area of ​​the rectangular through slot. The intermediate connecting disc passes through the threaded part and the drive intermediate shaft and is connected to the threaded part by a thread.

[0010] Preferably, a drive motor is installed on one side of the support frame, and a second bevel gear is installed on the output shaft end of the drive motor. The upper inner end of the second bevel gear is meshed with a first bevel gear, and the first bevel gear is coaxially connected to the drive intermediate shaft.

[0011] Preferably, the upper end of the support frame is provided with a front shuttle webbing limiting component and a rear shuttle webbing limiting component along the front and rear ends of the intermediate correction roller, respectively, and the front shuttle webbing limiting component and the rear shuttle webbing limiting component have the same structure.

[0012] Preferably, both the front shuttle webbing limiting assembly and the rear shuttle webbing limiting assembly include an upper pressure roller and a lower pressure roller, with the upper pressure roller located above the lower pressure roller, and the main body of the shuttle webbing passing between the upper pressure roller and the lower pressure roller.

[0013] Preferably, the front and rear ends of the upper end of the support frame are fixed with the support frame by screws, and both ends of the upper and lower pressure rollers are connected to the second support frame by bearings.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this utility model, the drive motor drives the second bevel gear to rotate, which in turn drives the drive intermediate shaft and the first bevel gear to rotate. Through the threaded connection between the threaded part outside the drive intermediate shaft and the threaded connection of the intermediate connecting plate, the two correction components move synchronously in the opposite direction of the offset to perform correction. The correction amplitude is easier to control. Moreover, the main body of the woven belt is driven to move horizontally, which has little impact on the overall tension and does not affect the overall conveying process.

[0016] (2) In this utility model, during the correction process, the correction component can maintain the force of the first pressure roller and the second pressure roller on the woven belt when it moves, so that the woven belt will not be deformed in a local position due to being driven to translate during the correction process, thus avoiding wrinkles in the woven belt caused by the correction action, ensuring the flatness of the woven belt and improving the product qualification rate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figures 1-6 The present invention provides an embodiment of a woven ribbon correction device, which mainly includes a support frame 1, a first support frame 2, an intermediate correction roller 3, a correction component 11, a drive mechanism, a front woven ribbon limiting component 18, and a rear woven ribbon limiting component 19.

[0026] There are two support frames 1, which provide a stable support foundation for the entire device. A first support frame 2 is fixed to the upper middle position of the support frame 1 with screws. An intermediate correction roller 3 connects the two first support frames 2 to accommodate the transmission requirements of the woven belt. Rectangular through slots 4 are formed from top to bottom on both outer sides of the intermediate correction roller 3. Simultaneously, a limiting sliding groove 5 is formed inside the intermediate correction roller 3 along the direction of the rectangular through slots 4. The rectangular through slots 4 and the limiting sliding groove 5 provide guidance and limitation for the movement of the correction assembly 11, ensuring that the correction assembly 11 can move smoothly along the predetermined direction.

[0027] The correction assembly 11 is the key component for realizing the correction function of this device. The correction assembly 11 includes an outer sliding ring 12, a rectangular sliding plate 13, and an intermediate connecting plate 14. The outer sliding ring 12 is slidably connected to the outside of the intermediate correction roller 3, allowing the correction assembly 11 to slide on the intermediate correction roller 3. The rectangular sliding plate 13 is fixed inside the outer sliding ring 12, and the intermediate connecting plate 14 is located at the middle position of the rectangular sliding plate 13. The rectangular sliding plate 13 and the intermediate connecting plate 14 slide within the rectangular through slot 4 and the limiting sliding groove 5, which limits their movement. This limiting sliding design ensures the stability and accuracy of the correction assembly 11 during movement, preventing the correction assembly 11 from shaking or shifting, thereby improving the correction accuracy. Between the two outer sliding rings 12, a first pressure roller 15 and a second pressure roller 16 are rotatably connected to the outside of the intermediate correction roller 3 via bearings. The first pressure roller 15 and the second pressure roller 16 are alternately arranged, and the number of first pressure rollers 15 is one more than the number of second pressure rollers 16. The woven tape body 17 wraps around the inside of the first pressure roller 15 and exits from the outside of the second pressure roller 16, making the woven tape body 17 wavy outside the multiple first pressure rollers 15 and second pressure rollers 16. This wavy winding method increases the friction between the woven tape body 17 and the first pressure rollers 15 and second pressure rollers 16, which can better guide the transmission of the woven tape body 17. In addition, during the correction process, the first pressure rollers 15 and second pressure rollers 16 can apply a certain force to the woven tape body 17, ensuring that the woven tape body 17 does not wrinkle during the correction process, thus improving the transmission quality of the woven tape body 17.

[0028] An intermediate drive shaft 6 is rotatably connected inside the intermediate correction roller 3. The intermediate drive shaft 6 is the power transmission component that drives the correction assembly 11 to move. A threaded portion 7 is fixed to the outside of the intermediate drive shaft 6 within the area of ​​the rectangular through slot 4. An intermediate connecting plate 14 passes through the threaded portion 7 and the intermediate drive shaft 6, and is threadedly connected to the threaded portion 7. When the intermediate drive shaft 6 rotates, due to the threaded connection between the threaded portion 7 and the intermediate connecting plate 14, the intermediate connecting plate 14 moves axially along the intermediate drive shaft 6, thereby driving the entire correction assembly 11 to move and achieve the correction function.

[0029] To drive the intermediate drive shaft 6 to rotate, a drive motor 9 is installed on one side of the support frame 1. A second bevel gear 10 is installed on the output shaft end of the drive motor 9, and a first bevel gear 8 is meshed with the upper inner side of the second bevel gear 10. The first bevel gear 8 is coaxially connected to the intermediate drive shaft 6. When the drive motor 9 starts, its output shaft drives the second bevel gear 10 to rotate, and the second bevel gear 10 drives the first bevel gear 8 to rotate through the meshing relationship, thereby driving the intermediate drive shaft 6 to rotate, providing power for the movement of the correction assembly 11. This bevel gear transmission method can change the direction of power transmission, making the entire device more compact and its operation more stable.

[0030] At the upper end of the support frame 1, a front shuttle webbing limiting component 18 and a rear shuttle webbing limiting component 19 are respectively arranged along the front and rear ends of the intermediate correction roller 3, and the front shuttle webbing limiting component 18 and the rear shuttle webbing limiting component 19 have the same structure. Both the front shuttle webbing limiting component 18 and the rear shuttle webbing limiting component 19 include an upper pressure roller 21 and a lower pressure roller 22, with the upper pressure roller 21 located above the lower pressure roller 22. The shuttle webbing body 17 passes between the upper pressure roller 21 and the lower pressure roller 22. The upper pressure roller 21 and the lower pressure roller 22 can limit and guide the shuttle webbing body 17, ensuring that the shuttle webbing body 17 can maintain a stable transmission state when entering and leaving the correction area, preventing the shuttle webbing body 17 from running off track or shaking during transmission, and further improving the transmission accuracy and stability of the shuttle webbing body 17.

[0031] The front and rear ends of the upper support frame 1 are fixed with second support frames 20 by screws. The two ends of the upper pressure roller 21 and the lower pressure roller 22 are connected to the second support frames 20 by bearings. The second support frames 20 provide stable support for the upper pressure roller 21 and the lower pressure roller 22, so that the upper pressure roller 21 and the lower pressure roller 22 can rotate smoothly, ensuring the smooth transmission of the woven belt body 17.

[0032] The working principle of this device is as follows: The main body 17 of the traction webbing first passes between the upper pressure roller 21 and the lower pressure roller 22 of the front webbing limiting assembly 18. The upper pressure roller 21 and the lower pressure roller 22 initially limit and guide the main body 17 of the webbing, allowing it to smoothly enter the correction area. Next, the main body 17 of the webbing wraps around the inside of the first pressure roller 15, then wraps around the outside of the adjacent second pressure roller 16, and sequentially winds around the first pressure roller 15, the second pressure roller 16 and the intermediate correction roller 3. Finally, it wraps around the first pressure roller 15 and the intermediate correction roller 3, and then passes between the upper pressure roller 21 and the lower pressure roller 22 of the rear webbing limiting assembly 19, completing the entire transmission process.

[0033] During the transmission of the woven ribbon body 17, the visual sensing component on the front external conveying structure detects the offset of the woven ribbon body 17 in real time. When an offset is detected, the control element precisely controls the output shaft of the drive motor 9 to drive a fixed number of turns according to the direction and degree of the offset. After the drive motor 9 starts, its output shaft drives the second bevel gear 10 to rotate, and the second bevel gear 10 drives the first bevel gear 8 to rotate through a meshing relationship, thereby driving the drive intermediate shaft 6 to rotate. Due to the threaded connection between the threaded part 7 on the outside of the drive intermediate shaft 6 and the intermediate connecting plate 14, the two correction components 11 will move synchronously in the opposite direction of the offset, thereby correcting the offset of the woven ribbon body 17. During the movement of the correction components 11, the first pressure roller 15 and the second pressure roller 16 always maintain a force on the woven ribbon body 17, so that the woven ribbon body 17 is always in a taut state during the correction process, avoiding wrinkles in the woven ribbon body 17 and ensuring the flatness and processing quality of the woven ribbon body 17.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
