[0001] The utility model belongs to the technical field of advertising paper processing, in particular to a roll material loading vehicle. Background Art

[0002] With the development of the advertising industry, advertising paper, as a key printing material, is widely used in advertising, packaging, poster production, and other fields. To improve production efficiency and processing precision, advertising paper is typically processed in roll form, that is, large rolls of advertising paper are processed for easy storage and transportation. During the processing, these rolls need to be loaded into specialized equipment before entering the subsequent steps of printing, cutting, coating, etc.

[0003] Currently, commercially available roll-loading carts are primarily used to transport advertising paper rolls from storage to processing equipment. They typically push or pull the rolls through the cart to the equipment's feed port for subsequent processing. However, in practice, existing roll-loading carts have numerous shortcomings, particularly in positioning and stably loading rolls of varying volumes, sizes, and weights, which present significant technical challenges.

[0004] First, existing coil loading carts are mostly universal in design, lacking effective positioning and adaptation for coils of varying specifications. This results in the coils easily shifting and tilting during the loading process due to a lack of precise coordination between the coil and the cart. This is especially true for large or irregularly shaped coils, where the coils are less stable and prone to drifting or rolling, further impacting loading accuracy. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0055] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0056] Example 1:

[0057] like Figure 1-Figure 4 As shown, this embodiment provides a coil loading vehicle, comprising:

[0058] A mobile vehicle 1 is provided with a lifting mechanism 10, which is used to adjust the height of the coil loading according to the height of the equipment;

[0059] The support plate 2 is arranged on the lifting mechanism 10;

[0060] The mounting frame 3 is mounted on the support plate 2 by means of bolt connection;

[0061] The disc 4 is arranged on the front side of the mounting frame 3;

[0062] A fixed shaft 5 is provided on the disc 4;

[0063] The barrel 6 is provided on the disc 4, and the fixed shaft 5 is located inside the barrel 6. The barrel 6 is used to be inserted into the material roll and to load the material;

[0064] The positioning mechanism 7 is provided on the fixed shaft 5 and cooperates with the barrel 6 to position the coil inserted into the barrel 6;

[0065] The positioning mechanism 7 includes:

[0066] There are multiple electric guide rails 71, which are evenly spaced along the circumferential direction of the fixed shaft 5;

[0067] The electric slider 72 is slidably arranged at both ends of the electric guide rail 71;

[0068] A support shaft 73 is provided on the electric slider 72;

[0069] The rotating plate 74 is rotatably mounted on the supporting shaft 73;

[0070] The rotating shaft 75 is rotatably disposed on the upper end of the rotating plate 74;

[0071] Connecting plates 76 are provided at both ends of the rotating shaft 75;

[0072] A positioning block 77 is provided between the four connecting plates 76 on the same side;

[0073] The through slots 78 are formed on the barrel 6 . The number of the through slots 78 is the same as that of the positioning blocks 77 , and they correspond one to one. The positioning blocks 77 extend out of the through slots 78 .

[0074] In this technical solution, the lifting mechanism 10 can be used to adjust the working height of the coil loading according to the different height requirements of the equipment and the working environment, so that the system can adapt to the heights of different coils, equipment and workbenches, ensuring the adaptability and flexibility of the loading process. Through the coordinated work of the barrel 6, the disc 4, the fixed shaft 5 and the positioning mechanism 7, it is ensured that the coil can be stably inserted into the barrel 6 during the loading process, and the position remains stable throughout the entire loading process without dislocation or sliding, thereby achieving efficient production operations. The positioning mechanism 7 can accurately control the positioning of the coil on the barrel 6. Through the coordinated action of the electric guide rail 71, the slider, the rotating shaft 75 and the positioning block 77 and other mechanisms, it can be ensured that when the coil is inserted into the barrel 6, the positioning block 77 is accurately docked with the through groove 78 on the barrel 6, ensuring that the coil is always in the correct position, thereby avoiding inaccurate loading or failure due to position deviation. The entire system can be easily moved and adjusted to a suitable loading height through the design of the mobile vehicle 1 and the adjustment of the lifting mechanism 10. The operator can adjust the height of the equipment through simple control means, and there is no need to manually intervene in the positioning and plugging process, which improves work efficiency and reduces labor intensity.

[0075] Workflow: The equipment is moved to the area where material loading is required using mobile cart 1. The flexible design of mobile cart 1 allows it to smoothly navigate the work environment and quickly move to the target location. The lifting mechanism 10 electrically or manually adjusts the overall height of barrel 6 based on the required working height, ensuring that barrel 6 is aligned with the center of the coil and allows the coil to be smoothly inserted into barrel 6. This process allows the equipment to adapt to workbenches or production lines of varying heights. Once the equipment height is adjusted to the appropriate position, the operator activates the system, and barrel 6 is moved to the coil insertion position, where it is securely inserted. The positioning mechanism 7 starts to work, the electric slider 72 slides along the electric guide rail 71, and the two ends of the slider drive the support shaft 73, so that the rotating plate 74 and the rotating shaft 75 thereon rotate. The connecting plates 76 at both ends of the rotating shaft 75 slide and rotate to make the positioning block 77 accurately extend and enter the through groove 78 on the barrel 6. The positioning block 77 moves to contact the inner wall of the coil to ensure the correct docking between the coil and the barrel 6. The positioning block 77 can firmly fix the coil on the barrel 6 to prevent any displacement or deviation of the coil during the loading process, ensuring that the coil is always in the correct working position. After the positioning block 77 is perfectly docked with the through slot 78, the coil has been firmly inserted into the barrel 6. Next, the mobile vehicle 1 can be moved to the position where the material needs to be loaded, and then the lifting mechanism 10 is started. The lifting mechanism 10 drives the barrel 6 to move up and down, thereby adjusting the coil to a position suitable for the equipment. The cooperation between the positioning block 77 and the coil allows the coil to remain stable during the transfer and lifting process. When the coil is adjusted to a suitable position, the electric slider 72 moves in the opposite direction along the electric guide rail 71, so that the electric slider 72 drives the support shaft 73 to move, so that the rotating plate 74 and the rotating shaft 75 thereon rotate in the opposite direction, and the connecting plates 7 at both ends of the rotating shaft 75 rotate in the opposite direction. 6 drives the positioning block 77 to move into the inside of the barrel 6, and the positioning block 77 moves into the inside of the barrel 6 through the through slot 78, so that the positioning block 77 is out of contact with the coil. At this time, the coil is loosened, making it easier to load the coil on the barrel 6 into the equipment. This allows for rapid adjustment at different heights and between equipment, ensuring that each coil insertion and positioning are accurate. It can also be adjusted according to different coil specifications to adapt to different production needs, achieving efficient, stable and accurate coil loading, ensuring accurate positioning of the coil during the loading process, avoiding errors and operating difficulties, thereby improving work efficiency and reducing operating risks.

[0076] like Figure 1 and Figure 2 As shown, in this embodiment, the fixed shaft 5 is optimized to be provided with a guide mechanism 8 for guiding the electric slider 72. The guide mechanism 8 includes:

[0077] The ear plates 81 are provided on the fixed shaft 5 and are located at both ends of the electric guide rail 71;

[0078] The guide rod 82 is provided on the electric slider 72 , and the guide rod 82 is slidably connected to the ear plate 81 .

[0079] In this technical solution, the guide mechanism 8 provides a stable guide and sliding path, so that the electric slider 72 is more stable during operation, reducing errors or mechanical failures caused by unstable slider movement.

[0080] Specifically, the guide mechanism 8 comprises a lug 81 and a guide rod 82. These structures ensure that the motorized slider 72 does not deviate from its predetermined trajectory as it moves along the motorized guide rail 71, thereby ensuring the precise alignment between the positioning block 77 and the through slot 78. This improvement enhances the overall positioning accuracy, reliability, and efficiency of the system. As the motorized slider 72 slides along the motorized guide rail 71, the guide rod 82 ensures a stable path and prevents positioning errors caused by slider deviation or vibration.

[0081] like Figure 1 and Figure 2 As shown, in this embodiment, the positioning block 77 is optimized and provided with an anti-slip layer 9 .

[0082] In this technical solution, the anti-slip layer 9 enhances the friction between the positioning block 77 and the coil, preventing the coil from slipping or loosening. This ensures the stability and accuracy of the coil during loading, prevents problems such as inaccurate positioning and coil misalignment caused by slippage, and improves the accuracy and safety of the system. It also prevents the positioning block 77 from slipping due to external forces or vibration during the coil loading process. The anti-slip layer 9 enhances the gripping ability of the positioning block 77, allowing it to firmly secure the coil and ensure precise positioning every time the coil is inserted.

[0083] Example 2:

[0084] This embodiment provides a coil loading vehicle, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0085] like Figure 1 and Figure 4 As shown, in this embodiment, the lifting mechanism 10 is optimized and includes:

[0086] Support legs 101 are arranged around the top of the mobile vehicle 1;

[0087] The guide groove 102 is formed inside the support leg 101 and extends upward to pass through the support leg 101;

[0088] The telescopic support 103 is slidably disposed in the guide groove 102, and the telescopic support 103 extends out of the guide groove 102;

[0089] A chute 104 is provided on the leg 101 and is connected to the guide groove 102;

[0090] The fixed plate 105 is disposed on the telescopic support 103, and the fixed plate 105 extends out of the slide slot 104 and is slidably connected to the slide slot 104;

[0091] The lifting rod 106 is provided on the fixed plate 105 and is fixedly connected to the support plate 2;

[0092] A support frame 107 is provided between the four legs 101;

[0093] Mounting plates 108 are provided on both sides of the top of the support frame 107;

[0094] The transmission shaft 109 is rotatably disposed between the two mounting plates 108. There are two transmission shafts 109, one on each side of the mounting plates 108.

[0095] Push rod 1010, disposed at the bottom of telescopic support 103;

[0096] Rotating plates 1011 are provided at both ends of the transmission shaft 109;

[0097] A groove 1012 is provided on the rotating plate 1011 , and the push rod 1010 is located in the groove 1012 ;

[0098] The worm gear 1013 is mounted on the transmission shaft 109;

[0099] Motor 1014, mounted on support frame 107;

[0100] The worm 1015 is disposed on the output shaft of the motor 1014 , and the worm 1015 cooperates with the worm wheel 1013 .

[0101] In this technical solution, when the height of the coiled material needs to be adjusted, the motor 1014 is started, and the motor 1014 starts to run. The movement of the motor 1014 is transmitted to the worm gear 1013 through the worm 1015, so that the worm gear 1013 and the transmission shaft 109 rotate. As the transmission shaft 109 rotates, the rotating plate 1011 also rotates. Since the push rod 1010 is fixed to the bottom of the telescopic support 103 and is located in the groove 1012 of the rotating plate 1011, the push rod 1010 is rotated by the rotation of the rotating plate 1011. When moving in a straight line, the push rod 1010 drives the telescopic support 103 to move up and down along the guide groove 102, and the telescopic support 103 drives the fixed plate 105 to move upward along the slide groove 104, and the fixed plate 105 drives the lifting rod 106 to move upward, and the lifting rod 106 drives the support plate 2 to move upward, and the support plate 2 drives all the components thereon to move upward, and at the same time the barrel 6 and the positioning mechanism 7 move upward, and the barrel 6 drives the coil positioned by the positioning mechanism 7 to move upward, thereby adjusting the height of the coil loading. Once the height set by the user is reached, , the motor 1014 stops running, the barrel 6 is fixed, and then the positioning mechanism 7 is unlocked, thereby stopping the positioning of the coil, and then the coil can be loaded into the equipment. After the loading is completed, the motor 1014 is started to run in the reverse direction, and the motor 1014 drives the worm 1015 to rotate in the reverse direction. The worm 1015 cooperates with the worm gear 1013, so that the worm gear 1013 drives the transmission shaft 109 to rotate in the reverse direction. As the transmission shaft 109 rotates in the reverse direction, the rotating plate 1011 also rotates in the reverse direction. The rotating plate 1011 passes through the concave The groove 1012 drives the push rod 1010 to move downward, the push rod 1010 drives the telescopic support 103 to move downward along the guide groove 102, the telescopic support 103 drives the fixed plate 105 to move downward along the slide groove 104, the fixed plate 105 drives the lifting rod 106 to move downward, the lifting rod 106 drives the support plate 2 to move downward, the support plate 2 drives all the components thereon to move downward, and then the barrel 6 moves downward and resets, so that the height of the coil loading can be adjusted according to needs, providing a height-adjustable and easy-to-operate operation.

[0102] like Figure 4 As shown, in this embodiment, the optimization further includes a control unit 11, which is electrically connected to the motor 1014. The control unit 11 receives the height adjustment instruction input by the user and controls the operating state of the motor 1014 to adjust the height of the leg 101 accordingly.

[0103] In this technical solution, the operator inputs the desired coil loading height adjustment command through the user interface of control unit 11 (control unit 11 typically includes buttons, a touch screen, or other input methods). The user can conveniently select a specific height adjustment value. After receiving the user's height adjustment command, control unit 11 first processes the input data and calculates the required height change of support leg 101. At this point, control unit 11 determines the operating state of motor 1014 based on preset operating parameters (such as the maximum speed of motor 1014 and the lifting range of support leg 101). Control unit 11 controls the operation of motor 1014 through electrical connections. Upon receiving the control signal, motor 1014 begins operating, driving the telescopic support 103 to raise and lower, achieving quick and smooth adjustment to the desired height. Control unit 11 continuously monitors the status of telescopic support 103 to ensure that it is adjusted according to the set height, preventing errors or improper adjustment. When the support leg 101 reaches the required height, the control unit 11 will automatically stop the operation of the motor 1014. In this way, the operator only needs to input a simple height adjustment instruction, and the control unit 11 will automatically control the operation of the motor 1014 to adjust the height of the barrel 6. This not only improves the operational flexibility of the equipment, but also reduces manual intervention, improves operating efficiency and equipment stability, and increases safety and convenience during use.

[0104] Example 3:

[0105] This embodiment provides a coil loading vehicle, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0106] like Figure 1 and Figure 4 As shown, in this embodiment, the bottom of the mobile vehicle 1 is optimized and provided with universal wheels 12.

[0107] In this technical solution, the universal wheels 12 in the design of the coil loading cart allow it to move freely in any direction, not just in a straight line. This is particularly important in scenarios requiring frequent position changes or operation within confined spaces. The universal wheels 12 allow the equipment to quickly change direction and flexibly adjust its position, improving work efficiency. Without the universal wheels 12, the mobile cart 1 typically moves only in a straight line, requiring a certain amount of space or reversing to adjust steering. With the universal wheels 12, the mobile cart 1 can make a 360-degree turn on the spot, requiring no additional space for directional adjustment, allowing the equipment to operate smoothly even in confined working environments. The universal wheels 12 allow operators to more conveniently control the equipment, reducing the difficulty of directional adjustment. In confined spaces, the operator can easily control the movement path and turning angle of the mobile cart 1, ensuring precise parking and adjustment. The design of the universal wheels 12 reduces resistance during movement, especially when frequent movement is required, reducing the physical burden of manual pushing or operation. Operators no longer need to push the equipment forcefully, but can easily move the equipment by controlling the direction. The universal wheel 12 not only improves the maneuverability of the equipment, but also makes operation easier and more convenient, meeting the requirements of modern automation equipment for flexibility and efficiency.

[0108] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
