Description

Technical Field

[0001] This utility model relates to the field of centering device technology, and more specifically, to a centering device for a plush cloth roll sealing device. Background Technology

[0002] In the plush fabric roll sealing process, the centering device needs to transport and straighten the fabric via a conveyor belt to ensure that the edges of the subsequent roll sealing are aligned. Existing centering devices can rely on the rotating conveyor belt to move the fabric from the middle to the edge to achieve flat centering.

[0003] The existing conveyor belts are mostly fixed installation structures, with a fixed width conveyor gap between the upper and lower conveyor belts. When installing the fabric, one end of the fabric needs to be manually inserted through this gap. Since the plush fabric itself has a certain thickness and softness, and the conveyor gap needs to be designed to be narrow to match the thickness of the fabric, the fabric is easy to get stuck at the entrance of the gap during the insertion process, or the fabric wrinkles or the edges shift due to the limited operating space. The operator needs to repeatedly adjust the posture of the fabric, which not only increases the difficulty of operation, but also prolongs the installation time and reduces production efficiency. Utility Model Content

[0004] This invention proposes a plush fabric roll-sealing centering device to replace traditional manual pushing, avoiding fabric wrinkles and edge misalignment caused by uneven manual pushing force; at the same time, the symmetrical design and synchronous transmission of the upper and lower conveyor belts ensure that the fabric is subjected to balanced force during the conveying process and always remains flat, further improving the quality of the fabric before roll-sealing, shortening the installation and conveying time, and improving production efficiency.

[0005] This utility model discloses a plush fabric roll sealing and centering device, comprising two symmetrically arranged mounting frames. The inner walls of the two mounting frames are respectively rotatably connected to two conveying rollers in an upper and lower structure. Each conveying roller is fitted with a conveyor belt on its outer wall, and each conveyor belt is fitted with a transmission shaft. The conveying rollers are driven by the conveyor belts and the transmission shafts. A fixed frame is rotatably connected to the end of each transmission shaft. Multiple fixed plates are fixedly connected between the two mounting frames. Multiple support frames are fixedly connected to the outer walls of each fixed plate. A cylinder is rotatably connected between the two support frames. A connecting shaft is rotatably connected to the output end of the cylinder. Support plates are fixedly connected to both ends of the connecting shaft. The support plates are fixedly connected to the fixed frames.

[0006] Preferably, a plurality of guide rollers are rotatably connected between the two mounting brackets.

[0007] Preferably, the outer wall of the mounting frame is provided with mounting grooves, and the end of the conveying roller extends into the mounting groove.

[0008] Preferably, the ends of the two conveying rollers located within the same mounting frame are fixedly connected to gears, and the two gears mesh with each other.

[0009] Preferably, each of the mounting slots is fixedly connected to a stepper motor, and the output end of the stepper motor is fixedly connected to the end of the conveyor roller located above.

[0010] Preferably, a reinforcing rib is provided between the fixing plate and the mounting bracket to enhance structural stability.

[0011] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0012] 1. In this application, by setting up a cylinder, a fixed frame, and a conveyor belt, the cylinder drives the active expansion and contraction of the gap between the upper and lower conveyor belts. When threading the material, the gap is widened to solve the problem of difficult material threading in narrow gaps and avoid the fabric getting stuck. After threading, the material is reset to a narrow gap of suitable thickness to ensure the centering accuracy of the conveyor. This completely eliminates the repeated adjustment process when threading the material manually, reducing the difficulty of operation. The transmission cooperation between the conveyor roller and the conveyor belt realizes the material conveying, replacing the traditional manual pushing and avoiding fabric wrinkles and edge deviation caused by uneven manual pushing force. At the same time, the symmetrical design and synchronous transmission of the upper and lower conveyor belts ensure that the force is balanced during the material conveying process, keeping it flat at all times. This further improves the quality of the material before sealing, shortens the installation and conveying time, and improves production efficiency.

[0013] 2. In this application, the mounting groove provides rotation and movement space for the end of the conveyor roller, ensuring that the conveyor roller does not have a rigid collision with the mounting frame when the cylinder adjusts the gap, thus avoiding damage to the components; at the same time, the mounting groove can limit the range of motion of the conveyor roller, prevent the conveyor belt from detaching due to excessive gap adjustment, and ensure the stability of the device operation.

[0018] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figures 1-3 As shown, a plush fabric roll sealing and centering device includes two symmetrically arranged mounting frames 1. The inner walls of the two mounting frames 1 are respectively rotatably connected to two conveyor rollers 11 in an upper and lower structure. The outer walls of the conveyor rollers 11 are fitted with conveyor belts 10, and the conveyor belts 10 are fitted with conveyor shafts 12. The conveyor rollers 11 are connected to the conveyor shafts 12 through the conveyor belts 10. The ends of the conveyor shafts 12 are rotatably connected to fixed frames 9. Multiple fixed plates 3 are fixedly connected between the two mounting frames 1. Multiple support frames 4 are fixedly connected to the outer walls of the fixed plates 3. A cylinder 7 is rotatably connected between the two support frames 4. The output end of the cylinder 7 is rotatably connected to a connecting shaft 8. Both ends of the connecting shaft 8 are fixedly connected to support plates 13. The support plates 13 are fixedly connected to the fixed frames 9.

[0021] The structure of cylinder 7, support plate 13, and fixed frame 9 enables flexible adjustment of the gap between the upper and lower conveyor belts 10, solving the technical problems of difficulty in threading material and easy jamming caused by traditional fixed gaps. The transmission cooperation between the conveyor roller 11 and the conveyor belt 10 replaces manual pushing of the fabric, avoiding wrinkles and deviations caused by manual operation and improving conveying efficiency. The symmetrical design of multiple fixed plates 3 and support frame 4 ensures the overall structural stability of the device and meets the needs of long-term continuous conveying of plush fabric.

[0022] The symmetrically arranged mounting frame 1 and the synchronously driven conveyor belt 10 provide balanced lateral constraints for the fabric, preventing edge shifting of the fabric during conveying.

[0023] like Figure 1 As shown, multiple guide rollers 5 are rotatably connected between the two mounting frames 1. The guide rollers 5 reduce the frictional resistance between the fabric and the device through rolling support, and avoid surface damage to the fabric caused by friction jamming during the fabric feeding and conveying process.

[0024] like Figure 1 As shown, mounting grooves 2 are provided on the outer wall of the mounting frame 1, and the end of the conveyor roller 11 extends into the mounting groove 2. The mounting groove 2 provides rotation and movement space for the end of the conveyor roller 11, ensuring that the conveyor roller 11 does not rigidly collide with the mounting frame 1 when the cylinder 7 adjusts the gap, thus avoiding damage to the components; at the same time, the mounting groove 2 can limit the range of motion of the conveyor roller 11, preventing the conveyor belt 10 from detaching due to excessive gap adjustment, and ensuring the stability of the device operation.

[0025] like Figure 3As shown, gears 14 are fixedly connected to the ends of the two conveying rollers 11 located in the same mounting frame 1, and the two gears 14 mesh with each other. The meshing transmission of the two gears 14 ensures that the upper and lower conveying rollers 11 rotate synchronously in opposite directions, so that the conveying force of the upper and lower conveyor belts 10 on the fabric is balanced, avoiding fabric wrinkles or deviations caused by differences in conveying speed; the gears 14 have high transmission efficiency and stable transmission ratio, adapting to the conveying needs of plush fabrics of different thicknesses, ensuring that the fabric remains flat during the conveying process.

[0026] like Figure 2 and Figure 3 As shown, stepper motors 6 are fixedly connected to the inner wall of the mounting groove 2, and the output ends of the stepper motors 6 are fixedly connected to the ends of the conveyor rollers 11 located above. The stepper motors 6 can control the rotation speed of the conveyor rollers 11 through pulse signals, thereby adjusting the conveying speed of the conveyor belt 10 to adapt to the rhythm requirements of different sealing processes. The motors are directly fixedly connected to the conveyor rollers 11, reducing transmission losses, ensuring stable power transmission, and avoiding conveying interruptions caused by slippage of the conveyor belt 10. The control method of the stepper motors 6 is existing technology and will not be described in detail here.

[0027] A reinforcing rib is provided between the fixing plate 3 and the mounting bracket 1 to enhance structural stability.

[0028] Working principle: The cylinder 7 is activated, and its output end drives the support plate 13 to rotate via the connecting shaft 8. The support plate 13 then drives the fixed frame 9 and the conveyor shaft 12 to rotate around the axis of the conveyor roller 11. Since the conveyor shaft 12 and the conveyor roller 11 are connected by the conveyor belt 10, the rotation of the conveyor shaft 12 drives the conveyor belt 10 to move synchronously, increasing the gap between the upper and lower sets of conveyor belts 10. The mounting groove 2 provides movement space for the end of the conveyor roller 11, ensuring that the conveyor roller 11 does not interfere with the mounting frame 1 when adjusting the gap, thus solving the problems of narrow material entry and easy jamming in traditional fixed gaps.

[0029] Place one end of the plush fabric on the guide roller 5. The guide roller 5 provides support and guidance for the fabric by rolling, avoiding friction and jamming caused by the fabric directly contacting the mounting frame 1. The operator feeds the end of the fabric into the widened conveyor gap along the guide roller 5. The wide gap design greatly reduces the difficulty of threading the fabric, eliminating the need to repeatedly adjust the fabric posture and preventing the fabric from wrinkling or shifting at the edges due to limited operating space.

[0030] After the fabric end passes through the conveyor gap, the reverse-start cylinder 7 drives the transmission shaft 12 and the conveyor belt 10 to reset, causing the gap between the upper and lower conveyor belts 10 to shrink to a preset width suitable for the thickness of the plush fabric; the stepper motor 6 is started, and its output end drives the upper conveyor roller 11 to rotate. The upper conveyor roller 11 drives the lower conveyor roller 11 to rotate synchronously in the opposite direction through the meshing gear 14. During the fabric conveying process, the upper and lower conveyor belts 10 push the fabric from the middle to the edge to avoid fabric deviation and achieve centering conveying.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
