Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label manufacturing technology, and in particular to a self-adhesive label cutting roller. Background Technology

[0002] A self-adhesive label cutting roller is a precision tool used to cut continuous rolls of self-adhesive label material into individual labels. It is usually installed on label printers or labeling machines. Through rotational motion, it precisely cuts the self-adhesive label material to a preset length or shape. During cutting, the entire roll of self-adhesive labels is placed on the unwinding rack, and then passed between the upper and lower rollers. The upper roller is equipped with a circular cutting blade, which cuts the self-adhesive labels.

[0003] Traditional lower rollers are typically made of stainless steel. However, during the cutting process of self-adhesive labels, the cutting blade inevitably comes into contact with the surface of the lower roller. Over time, a large number of cutting marks will gradually accumulate on the surface of the lower roller. Once the marks accumulate to a certain extent, a new lower roller must be replaced, otherwise the cutting quality will be seriously affected. However, frequent replacement of stainless steel rollers will inevitably lead to a significant increase in costs. In addition, traditional cutting rollers have poor adaptability to label materials of different thicknesses, hardnesses and materials. The adjustment process is cumbersome and relies too much on the operator's experience, making it difficult to quickly switch to produce labels of different specifications, thus negatively impacting production efficiency.

[0004] Therefore, those skilled in the art have provided a self-adhesive label cutting roller to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-adhesive label cutting roller. The roller uses a first servo motor to control the position of the sliding block, adjust the distance and pressure between the upper roller and the rubber outer roller, and adapt to materials of different thicknesses and hardnesses. The rubber outer roller is made of highly wear-resistant material, which reduces material damage due to its flexibility and improves the yield rate. Furthermore, the rubber material saves on maintenance costs. In addition, the device adopts a modular design for easy maintenance and replacement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-adhesive label cutting roller includes a mounting plate, an upper roller, and a cross-shaped inner roller. A bidirectional threaded rod is rotatably connected to one side of the upper surface of the mounting plate. A first servo motor is mounted on the upper end of the bidirectional threaded rod, and the output end of the first servo motor is fixedly connected to the middle of the upper end of the bidirectional threaded rod. A guide rod is fixedly connected to the other side of the upper surface of the mounting plate. Two sliding blocks are sleeved on the outer walls of both the guide rod and the bidirectional threaded rod. A third servo motor is fixedly connected to the inner wall of the other side of one of the sliding blocks at the lower end of one side. A second servo motor is fixedly connected to the output end of the third servo motor. The moving rod, the outer wall of the second rotating rod is fixedly connected to the inner wall of the cross inner roller, the upper and lower ends and the middle of the outer walls on both sides of the cross inner roller are all provided with grooves, and the outside of the grooves is provided with push rods. The outer wall of the push rod near the center of the cross inner roller is fixedly connected with multiple return springs. The outer wall of the cross inner roller is fitted with a rubber outer roller, and the middle of the rubber outer roller is provided with a cross groove. The inner wall of the cross groove is tightly fitted with the outer wall of the cross inner roller. The outer wall of the push rod away from the center of the cross inner roller is tightly fitted with the inner wall of the upper and lower ends and the middle of the two sides of the cross groove.

[0008] Through the above technical solution, the position of the sliding block controlled by the first servo motor can be adjusted to change the distance between the upper roller and the outer rubber roller, thereby changing the pressure between them. Different materials may require different cutting or imprinting pressures. This equipment can adapt to materials of different thicknesses and hardnesses. The surface of the outer rubber roller is made of highly wear-resistant rubber material, which effectively resists friction with the label material during the cutting process, extends the service life of the roller, and the softness of the outer rubber roller helps to reduce damage to the label material, avoid problems such as tearing or deformation, and improve the label yield. In addition, the outer rubber roller adopts a modular design, which is easy to disassemble and replace, and facilitates daily maintenance. The third servo motor directly drives the inner cross roller through the second rotating rod, which has high transmission efficiency and fast response speed.

[0009] Furthermore, bearings are fixedly connected to the inner wall of the sliding block on the other side, and mounting grooves are opened on the outer wall of the bearing side. A rotating ring is provided inside the mounting groove, and multiple balls are fixedly connected to the outer wall of the rotating ring. The outer walls of the balls rotate and fit against the inner wall of the mounting groove. A second servo motor is fixedly connected to the inner wall of the sliding block on the other side of the upper end of one side. A first rotating rod is fixedly connected to the output end of the second servo motor. The outer wall of the other side of the upper first rotating rod is fixedly connected to the inside of the rotating ring. An upper roller is fixedly connected to the outer wall of the first rotating rod, and multiple cutting blades are fixedly connected to the outer wall of the upper roller.

[0010] Through the above technical solution, the rotation speed and angle of the first rotating rod can be controlled by the second servo motor, thereby realizing the control of the upper roller and the cutting blade, ensuring the accuracy and quality of cutting. Through the structural design of the ball and rotating ring, low-friction rotational motion is achieved, which improves cutting efficiency and reduces energy loss. The modular design makes each component easy to disassemble and install, and convenient for maintenance and replacement.

[0011] Furthermore, the outer wall on the other side of the lower end of the second rotating rod is fixedly connected to the inner wall;

[0012] The above technical solution and design help to reduce vibration and deviation during the movement of the second rotating rod.

[0013] Furthermore, a limit block is fixedly connected to the upper end of the guide rod, and the upper ends of both the limit block and the first servo motor are fixedly connected to components of the label printer or labeling machine.

[0014] Through the above technical solution, the main function of the limiting block is to limit the movement range of the sliding block on the guide rod. By fixing both the limiting block and the first servo motor on the machine, the stability of the entire cutting roller structure can be improved.

[0015] Furthermore, the inner wall of one side of the sliding block is threadedly connected to the outer wall of the bidirectional threaded rod, and the inner wall of the other side of the sliding block is slidably attached to the outer wall of the guide rod.

[0016] The above technical solution enhances the rigidity of the entire structure by combining threaded connection and sliding fit, thereby improving the stability and durability of the cutting roller.

[0017] Furthermore, the outer wall of the rubber outer roller is provided with cutting grooves, and the cutting blades correspond to the cutting grooves.

[0018] The above technical solution and design can effectively prevent the cutting blade from shifting or shaking during the cutting process, thereby ensuring a smooth and neat cutting edge.

[0019] Furthermore, one end of each reset spring near the center of the cross inner roller is fixedly connected to the inner wall of the groove;

[0020] The above technical solution ensures that the return spring provides stable and continuous pressure regardless of how the inner cross roller rotates or is subjected to external force, so that the push rod always presses against the outer rubber roller.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a self-adhesive label cutting roller. By controlling the position of the sliding block through a first servo motor, the distance between the upper roller and the rubber outer roller can be adjusted, thereby changing the pressure between the two. Different materials may require different cutting or imprinting pressures. This equipment can adapt to materials of different thicknesses and hardnesses. The surface of the rubber outer roller is made of highly wear-resistant rubber material, which effectively resists friction with the label material during the cutting process, extends the service life of the roller, and the softness of the rubber outer roller helps to reduce damage to the label material, avoid problems such as tearing or deformation, and improve the label yield. In addition, the rubber outer roller adopts a modular design, which is easy to disassemble and replace, and facilitates daily maintenance and upkeep.

[0023] 2.

The position of the sliding block 204 is controlled by the first servo motor 2, which can adjust the distance between the upper roller 302 and the outer rubber roller 502, thereby changing the pressure between them. Different materials may require different cutting or imprinting pressures. This equipment can adapt to materials of different thicknesses and hardnesses.

The third servo motor 5 directly drives the inner cross roller 6 through the second rotating rod 501, which has high transmission efficiency and fast response speed.

[0033] Reference Figure 1 , Figure 2 and Figure 5 On the other side, the inner wall of one side of the sliding block 204 is fixedly connected to a bearing 4, and the outer wall of one side of the bearing 4 is provided with a mounting groove 401. A rotating ring 402 is provided inside the mounting groove 401, and multiple balls 403 are fixedly connected to the outer wall of the rotating ring 402.

Through the structural design of the ball bearing 403 and the rotating ring 402, low-friction rotational motion is achieved, which improves cutting efficiency and reduces energy loss. The modular design makes each component easy to disassemble and install, and convenient for maintenance and replacement.

[0034] Reference Figure 1 and Figure 2 The outer wall of the second rotating rod 501 at the lower end is fixedly connected to the inner wall on the other side. This design helps to reduce vibration and deviation during the movement of the second rotating rod 501. The upper end of the guide rod 202 is fixedly connected to the limit block 203. The upper ends of the limit block 203 and the first servo motor 2 are both fixedly connected to the components of the label printer or labeling machine. The main function of the limit block 203 is to limit the movement range of the sliding block 204 on the guide rod 202. By fixing the limit block 203 and the first servo motor 2 to the machine, the stability of the entire cutting roller structure can be improved. The inner wall of one side of the sliding block 204 is threadedly connected to the outer wall of the bidirectional threaded rod 201, and the inner wall of the other side of the sliding block 204 is threadedly connected to the guide rod 202.

The outer wall of the rubber outer roller 502 is provided with cutting grooves 503, and the cutting blades 303 correspond to the cutting grooves 503. This design can effectively prevent the cutting blades 303 from shifting or shaking during the cutting process, thereby ensuring the smoothness and neatness of the cutting edge. The end of the return spring 603 near the center of the cross inner roller 6 is fixedly connected to the inner wall of the groove 601. This connection method ensures that no matter how the cross inner roller 6 rotates or is subjected to external force, the return spring 603 can provide stable and continuous pressure, so that the push rod 602 always presses against the rubber outer roller 502.

[0035] Working Principle: First, the self-adhesive label cutting roller is installed on the label printer or labeling machine, ensuring that the mounting plate 1, the first servo motor 2, and the limit block 203 are firmly connected to the machine to guarantee the stability of the entire structure. Then, based on the thickness and hardness of the label material to be cut, the first servo motor 2 controls the rotation of the bidirectional threaded rod 201, thereby adjusting the position of the sliding block 204. This adjusts the distance and pressure between the upper roller 302 and the rubber outer roller 502 to accommodate different materials. The third servo motor 5 directly drives the cross inner roller 6 to rotate via the second rotating rod 501, achieving efficient and rapid transmission while reducing vibration and deviation. The second servo motor 3 controls the rotation speed and angle of the first rotating rod 301, thereby controlling the upper roller 302 and the cutting blade. The cutting action of 303 ensures the precision and quality of the cutting. The second servo motor 3 and the third servo motor 5 rotate in opposite directions. The structural design of bearing 4, rotating ring 402 and ball bearing 403 realizes the low-friction rotation of the upper roller 302, thereby improving cutting efficiency and reducing energy loss. The return spring 603 provides stable and continuous pressure, so that the push rod 602 always presses against the rubber outer roller 502, ensuring that the cutting blade 303 runs stably in the cutting groove 503, avoiding deviation or vibration, thereby ensuring a smooth and neat cutting edge. The outer roller 502 adopts a modular design, which is easy to disassemble and replace, and facilitates daily maintenance. The rubber material saves maintenance costs. Other components such as sliding block 204 and bearing 4 also adopt a modular design, which is easy to maintain and replace.
