Description

Technical Field

[0001] This utility model relates to the field of conveying devices, specifically a self-adhesive paper conveying device. Background Technology

[0002] Stable, efficient, and accurate conveying of self-adhesive paper is crucial in its production and use. Traditional conveying systems often struggle to accommodate self-adhesive paper of varying widths and are prone to deviation during transport, impacting subsequent processing and usability. For instance, some simple conveying devices offer only a single guide path and cannot effectively limit the movement of self-adhesive paper of different widths, causing lateral shifts during transport. This not only wastes materials but also disrupts the continuity and efficiency of the entire production process.

[0003] Furthermore, tension control of the self-adhesive paper is crucial during transportation. Inappropriate tension can lead to problems such as overstretching, wrinkling, or loosening of the self-adhesive paper, affecting its quality and performance. Existing conveying devices typically lack a flexible tension adjustment mechanism and cannot be adapted to different production needs and working conditions. Therefore, we propose a self-adhesive paper conveying device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a self-adhesive paper conveying device, which solves the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a self-adhesive paper conveying device, including a mounting plate, a central limiting shaft rotatably mounted in the middle area of ​​the mounting plate, two position-adjustable limiting annular blocks provided on the central limiting shaft, two side mounting brackets connected to the mounting plate through a driving structure, the two side mounting brackets being located on both sides of the central limiting shaft, the side mounting brackets being U-shaped, and a side guide shaft rotatably mounted on the inner side of the side mounting brackets.

[0006] Preferably, the mounting plate has a rectangular groove, and a connecting block is slidably installed inside the rectangular groove. One side of the mounting plate is fixedly connected to the side mounting bracket, and the other side of the connecting block is connected to the drive structure.

[0007] Preferably, a rack is fixedly installed on the back of the intermediate limiting shaft above the drive structure, and the drive structure meshes with the rack.

[0008] Preferably, the drive structure includes a motor mounting base, a motor, and a gear. The motor mounting base is fixedly connected to the connecting block. The motor is fixedly mounted on the motor mounting base, and the gear is fixedly mounted on the output shaft of the motor. The gear meshes with a rack.

[0009] Preferably, a threaded rod is provided on the intermediate limiting shaft, and a connecting rod is integrally formed on the inner side of the limiting annular block corresponding to the position of the threaded rod. The connecting rod extends into the interior of the intermediate limiting shaft through a strip groove, and a threaded rod assembly is provided inside the intermediate limiting shaft. The threaded rod assembly is connected to the end of the connecting rod.

[0010] Preferably, the threaded rod assembly includes a threaded rod, a threaded ring, and a limiting frame. The threaded rod is rotatably mounted inside the intermediate limiting shaft, and the thread directions at both ends of the threaded rod are opposite. Each end of the threaded rod is threadedly connected to a threaded ring, and the two threaded rings are respectively fixedly connected to one end of a connecting rod mounted on a corresponding limiting ring block. A limiting frame is fixedly installed inside the intermediate limiting shaft, and the threaded rod passes through the limiting frame.

[0011] Preferably, a knob is fixedly installed at one end of the threaded rod that passes through the limiting frame.

[0012] Compared with the prior art, the present invention provides a self-adhesive paper conveying device, which has the following beneficial effects:

[0013] 1. This self-adhesive paper conveying device features two adjustable limiting ring blocks on its central limiting shaft. The spacing between these ring blocks can be easily adjusted via a threaded rod assembly, including a threaded rod, a threaded ring, and a limiting frame. This structure allows the device to precisely adjust the distance between the limiting ring blocks according to the width of the self-adhesive paper being transported, ensuring the paper remains stably positioned between the two ring blocks. Regardless of variations in the paper's width, this self-adhesive paper effectively limits its movement. This adaptive width adjustment prevents the paper from deviating during transport due to width differences, guaranteeing it follows the predetermined path, improving transport accuracy and stability, and reducing material waste and production interruption risks caused by deviation.

[0014] 2. This self-adhesive paper conveying device is equipped with a drive structure consisting of a motor mounting base, a motor, and gears. The motor drives the gears to rotate, which mesh with a rack on the intermediate limit shaft. This allows the motor mounting base to move laterally, which in turn moves the connecting block and the side mounting bracket laterally, ultimately moving the side guide shaft. This design allows users to flexibly change the distance between the intermediate limit shaft and the side guide shaft according to different production needs and the characteristics of the self-adhesive paper, thereby adjusting the guide tension. By changing the guide tension, problems such as excessive stretching, wrinkling, or loosening of the self-adhesive paper during transportation can be avoided, which helps improve the quality and performance of the self-adhesive paper and makes it better meet the requirements of subsequent processing or use.

[0015] 3. This self-adhesive paper conveying device rationally mounts all components onto the mounting plate. The compact arrangement of components such as the intermediate limit shaft and side mounting brackets, along with reasonable connection and transmission methods, reduces the overall space occupied by the device, facilitating installation and use in different production environments and improving space utilization. The side mounting bracket is U-shaped, with a side guide shaft rotatably mounted on its inner side. It works in conjunction with the intermediate limit shaft and limit ring block to form a simple yet effective guiding and limiting system, achieving multiple functions while maintaining the compactness of the device structure.

[0016] 4. For adjusting the spacing of the limit ring blocks, this self-adhesive paper conveying device only requires one hand to hold the middle limit shaft in place, and then rotating the knob will drive the threaded rod to rotate, thereby adjusting the spacing of the limit ring blocks. The operation is simple and intuitive, without the need for complicated tools or operating procedures. For adjusting the guide tension, only the motor needs to be started, and the position of the side guide shaft can be adjusted through the drive structure, which reduces the difficulty of operation for operators and improves the convenience of operation and work efficiency.

[0017] 5. This self-adhesive paper conveying device, with its stable limit and precise tension adjustment, avoids various quality problems that may occur during the conveying process, such as deviation, wrinkles, and stretching deformation. This ensures the quality of the self-adhesive paper when it enters subsequent processing steps, improves the quality of the final product, and provides a higher quality guarantee for the production and use of self-adhesive paper, helping to meet higher product quality standards and user needs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 A self-adhesive paper conveying device includes a mounting plate 1. A central limiting shaft 2 is rotatably mounted in the middle area of ​​the mounting plate 1. Two adjustable limiting ring blocks 16 are provided on the central limiting shaft 2. Two side mounting brackets 3 are connected to the mounting plate 1 through a drive structure. The two side mounting brackets 3 are located on both sides of the central limiting shaft 2. The side mounting brackets 3 are U-shaped. A side guide shaft 4 is rotatably mounted on the inner side of the side mounting bracket 3. When it is necessary to transport the self-adhesive paper, one end of the self-adhesive paper is guided through one side guide shaft 4. Then, according to the width of the self-adhesive paper, the distance between the two limiting ring blocks 16 is adjusted. Then, the paper is guided through the central limiting shaft 2, ensuring that the self-adhesive paper is between the two limiting ring blocks 16. Then, the paper is guided through the other side guide shaft 4. This device can adaptively adjust the limiting ring blocks 16 according to the width of the self-adhesive paper to be transported, thereby limiting and guiding the self-adhesive paper and preventing it from deviating during transport.

[0027] Furthermore, a rectangular groove 6 is provided on the mounting plate 1, and a connecting block 7 is slidably installed inside the rectangular groove 6. One side of the mounting plate 1 is fixedly connected to the side mounting bracket 3, and the other side of the connecting block 7 is connected to the drive structure.

[0028] Furthermore, a rack 11 is fixedly installed on the back of the intermediate limiting shaft 2 above the drive structure, and the drive structure meshes with the rack 11.

[0029] Furthermore, the drive structure includes a motor mounting base 8, a motor 9, and a gear 10. The motor mounting base 8 is fixedly connected to the connecting block 7. The motor 9 is fixedly mounted on the motor mounting base 8, and the gear 10 is fixedly mounted on the output shaft of the motor 9. The gear 10 meshes with the rack 11. When it is necessary to adjust the position of the side guide shaft 4 laterally to change the guiding tension, the motor 9 is started. The motor 9 drives the gear 10 to rotate. Due to the meshing, the motor mounting base 8 can be moved laterally, thereby driving the connecting block 7 and the side mounting bracket 3 to move laterally, thereby driving the side guide shaft 4 to move, changing the distance between the intermediate limit shaft 2 and the side guide shaft 4, and changing the guiding tension.

[0030] Furthermore, a threaded rod 13 is provided on the intermediate limiting shaft 2, and a connecting rod 15 is integrally formed on the inner side of the limiting ring block 16 corresponding to the position of the threaded rod 13. The connecting rod 15 extends into the interior of the intermediate limiting shaft 2 through the strip groove 12. A threaded rod assembly is provided inside the intermediate limiting shaft 2, and the threaded rod assembly is connected to the end of the connecting rod 15.

[0031] Furthermore, the threaded rod assembly includes a threaded rod 13, a threaded ring 14, and a limiting frame 17. The threaded rod 13 is rotatably installed inside the intermediate limiting shaft 2, and the thread directions at both ends of the threaded rod 13 are opposite. The two ends of the threaded rod 13 are respectively threadedly connected to the threaded ring 14. The two threaded rings 14 are respectively fixedly connected to one end of the connecting rod 15 installed on the corresponding limiting ring block 16. The limiting frame 17 is fixedly installed inside the intermediate limiting shaft 2, and the threaded rod 13 passes through the limiting frame 17.

[0032] Furthermore, a knob 5 is fixedly installed at one end of the threaded rod 13 that passes through the limit frame 17. When it is necessary to adjust the distance between the two limit ring blocks 16, one hand holds the middle limit shaft 2 to fix it, and then the knob 5 is rotated to drive the threaded rod 13 to rotate. Since the thread directions at both ends are different, the threaded rings 14 on both sides are driven to move laterally in different directions, thereby driving the connecting rod 15 to move, and then driving the two to move towards each other or away from each other, adjusting the distance between them.

[0033] Structural Description:

[0034] Mounting plate 1:

[0035] As the basic component of the entire device, it provides mounting locations for other components.

[0036] The middle area is rotatably mounted with a middle limit shaft 2, which bears the rotation function of the middle limit shaft.

[0037] A rectangular groove 6 is provided for installing a connecting block 7, allowing the connecting block to slide within the rectangular groove, thereby connecting it with the drive structure and the side mounting bracket 3, and providing space and guidance for the lateral movement of the drive structure and the side mounting bracket.

[0038] Intermediate limiting axis 2:

[0039] It is rotated and installed in the middle area of ​​the mounting plate 1, which serves to guide and limit the self-adhesive paper in the middle.

[0040] It is equipped with two adjustable limit ring blocks 16, which are closely related to the limiting function of the self-adhesive paper.

[0041] A rack 11 is fixedly installed on the back of the drive structure above it. By meshing with the gear 10 in the drive structure, the linkage between the intermediate limit shaft and the drive structure is realized.

[0042] The internal structure includes a threaded rod assembly, comprising a threaded rod 13, a threaded ring 14, and a limiting bracket 17, providing internal structural support for adjusting the spacing of the limiting ring blocks.

[0043] Side mounting bracket 3:

[0044] It is U-shaped, and a side guide shaft 4 is rotatably installed on its inner side. When the self-adhesive paper is transported, the self-adhesive paper will be guided from one side of the side guide shaft.

[0045] Installed on mounting plate 1, the lateral position is adjusted by the drive structure. It is located on both sides of the middle limiting shaft 2, and the connection with the mounting plate is achieved by the sliding fit of the connecting block 7 and the rectangular groove 6.

[0046] The lateral movement of the side mounting bracket can change the distance between the central limiting shaft and the side guide shaft, thereby changing the guide tension, which plays an important role in the tension adjustment of the self-adhesive paper.

[0047] Side guide shaft 4:

[0048] The rotatable mounting bracket 3 is installed on the inside of the side mounting bracket and is a guide component in the transportation process of the self-adhesive paper. When the self-adhesive paper is transported, it will first pass through the side guide shaft on one side, then through the middle limit shaft 2, and finally through the side guide shaft on the other side, ensuring the smooth and guided transportation path of the self-adhesive paper.

[0049] Knob 5:

[0050] It is fixedly installed at one end of the threaded rod 13 that passes through the limit bracket 17 for manual operation.

[0051] When the knob is rotated, the threaded rod 13 will rotate, thereby adjusting the distance between the two limit ring blocks 16. When adjusting the distance between the limit ring blocks, hold the middle limit shaft with one hand to fix it, and then rotate the knob to achieve precise adjustment of the position of the limit ring blocks.

[0052] Rectangular slot 6:

[0053] The mounting plate 1 provides a sliding track for the connecting block 7, ensuring smooth sliding of the connecting block inside. It is one of the key structures for the lateral movement of the side mounting bracket 3 and the drive structure, ensuring the structural stability and reliability of the entire device when adjusting the guiding tension.

[0054] Connector 7:

[0055] It is slidably installed inside the rectangular groove 6, with one side fixedly connected to the side mounting bracket 3 and the other side connected to the drive structure, transmitting the power of the drive structure to the side mounting bracket to realize the lateral movement of the side mounting bracket.

[0056] Motor mounting bracket 8:

[0057] It is fixedly connected to the connecting block 7, providing a stable installation position for the motor 9, ensuring that the motor will not shake or shift during operation, and providing a foundation for the stable operation of the entire drive structure.

[0058] Motor 9:

[0059] It is fixedly installed on the motor mounting base 8 and is the power source for the drive structure.

[0060] A gear 10 is fixedly installed on its output shaft. The rotation of the motor drives the gear to rotate, providing power for the lateral position adjustment of the entire device. When the motor starts, it can drive the gear 10 to rotate, thereby driving the lateral movement of the entire side mounting bracket 3.

[0061] Gear 10:

[0062] Installed on the output shaft of motor 9, it meshes with rack 11 to convert the rotational motion of the motor into linear motion. Through its cooperation with rack 11, it drives the lateral movement of motor mounting base 8, connecting block 7 and side mounting bracket 3, thereby changing the guiding tension.

[0063] Rack 11:

[0064] Fixedly installed on the back of the intermediate limit shaft 2 above the drive structure, it meshes with the gear 10 and is a key component for converting rotary motion into linear motion. By meshing with the gear, it transmits power and ensures the accuracy of power transmission and lateral position adjustment of the drive structure.

[0065] Slot 12:

[0066] Located on the intermediate limiting shaft 2, the connecting rod 15 extends into the interior of the intermediate limiting shaft 2 through the strip groove, providing space for the movement of the connecting rod and ensuring that the connecting rod can move smoothly when the spacing of the limiting ring block 16 is adjusted, without being obstructed by the intermediate limiting shaft.

[0067] Threaded rod 13:

[0068] Rotatably mounted inside the intermediate limit shaft 2, with opposite thread directions at both ends, it is a key component for adjusting the spacing of the limit ring blocks 16.

[0069] Its rotation can drive the threaded rings 14 at both ends to move laterally in different directions, thereby adjusting the spacing of the limiting ring blocks.

[0070] Threaded ring 14:

[0071] The threaded ring is threaded to both ends of the threaded rod 13 and fixedly connected to one end of the connecting rod 15 installed on the corresponding limiting ring block 16. When the threaded rod rotates, the threaded ring will move laterally on the threaded rod according to the direction of the thread, thereby driving the limiting ring block to move and realizing adaptive adjustment of the width of the self-adhesive paper.

[0072] Connecting rod 15:

[0073] The integrally formed inner side of the limiting ring block 16 corresponds to the position of the threaded rod 13, and extends to the interior of the intermediate limiting shaft 2 through the strip groove 12, connecting with the threaded rod assembly. It is a key component that transmits the movement of the threaded rod assembly to the limiting ring block, ensuring the spacing adjustment function of the limiting ring block.

[0074] Limiting ring block 16:

[0075] Installed on the middle limiting shaft 2, its position is adjustable. Its main function is to adjust the spacing according to the width of the self-adhesive paper, restrict the self-adhesive paper on the middle limiting shaft, ensure that the self-adhesive paper is located between the two limiting ring blocks, prevent the self-adhesive paper from deviating during transportation, and play a limiting and guiding role for the self-adhesive paper.

[0076] Limiter bracket 17:

[0077] Fixedly installed inside the intermediate limiting shaft 2, the threaded rod 13 passes through the limiting frame 17, which plays a role in limiting and supporting the threaded rod, ensuring the stability of the threaded rod during rotation, and ensuring the normal operation of the entire threaded rod assembly.

[0078] Working principle: When self-adhesive paper needs to be transported, one end of the self-adhesive paper is guided through the side guide shaft 4 on one side. Then, according to the width of the self-adhesive paper, the distance between the two limiting ring blocks 16 is adjusted. Then, it is guided through the middle limiting shaft 2, and it is necessary to ensure that the self-adhesive paper is between the two limiting ring blocks 16. Then, it is guided through the other side guide shaft 4. This device can adaptively adjust the limiting ring blocks 16 according to the width of the self-adhesive paper to be transported, so as to limit and guide the self-adhesive paper and prevent it from deviating during transportation.
