Description

Technical Field

[0001] This utility model relates to the field of winding technology, and more specifically, to a label winding mechanism. Background Technology

[0002] In existing technologies, label winding mechanisms often suffer from uneven label winding during the label winding process. Insufficient tension control and stable support for the winding shaft lead to bending, wrinkling, or uneven winding of the labels during the winding process. This not only affects the appearance quality of the labels but may also cause jamming or equipment damage during the winding process, reducing production efficiency.

[0003] Furthermore, the existing winding device's installation structure and position adjustment are not flexible enough, often requiring complex manual operations to adjust the angle or position of the winding equipment. This inconvenient installation and adjustment method forces production line workers to spend a significant amount of time and effort to ensure the equipment's normal operation. In some production environments, frequent adjustments or movements may lead to a decrease in the accuracy of the winding device, further affecting the winding quality.

[0004] More seriously, the maintenance and repair of existing label winding devices are inconvenient. Many equipment components are designed to be compact and lack sufficient maintenance space. Once a fault occurs or a component needs to be replaced, operators often need to disassemble multiple complex components to access the faulty part. This not only increases maintenance time and cost, but also easily leads to damage to other components due to improper operation, further exacerbating the difficulty of equipment maintenance.

[0010] The present invention is further provided that the base plate is provided with adjustment holes, and multiple sets of adjustment holes are provided. Multiple sets of adjustment holes can flexibly adjust the locking rods at different positions, so that the reel can be accurately positioned according to actual needs.

[0011] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixed at the bottom end of the adjustment hole, so that the clamping tube and the adjustment hole are connected. The connection between the connecting plate and the adjustment hole is as follows: the connecting plate is fixed at the bottom end of the adjustment hole, and the connection with the clamping tube further enhances the stability of the overall structure.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a label winding mechanism, which has the following advantages:

[0018] This invention features a pressing and conveying mechanism. The hydraulic cylinder provides precise pressure control, ensuring the label is pressed firmly against the base plate, preventing it from loosening or shifting, thereby improving the stability and accuracy of label winding. The fixed installation of the longitudinal frame and the directional sliding of the pressing frame ensure the longitudinal stability of the label during winding, keeping it in the correct position without deviation. The main and driven wheels help guide the label conveying evenly, reducing friction and preventing label damage, while also assisting in winding. The roller belt provides smooth transmission, making the rotation between the main and driven wheels smoother and ensuring the accuracy of label winding.

[0019] This utility model features a reel locking mechanism. The locking tube and locking rod design ensure that the reel is more securely fixed in the appropriate position during installation, ensuring the stability of the reel during the winding process and preventing loosening or falling off. The limiting teeth, in cooperation with the rotary tooth plate, can effectively limit the rotation range, thereby ensuring a firm connection between the locking rod and the locking tube and preventing the reel from accidentally slipping off during operation. The embedded plate further ensures that the locking rod is fixed inside the locking tube, enhancing the locking stability and preventing the reel from shifting or falling off under high load.

[0020] This invention features a locking auxiliary mechanism. The design of the base block and multiple spring rods ensures stable locking of the limiting teeth and prevents unnecessary slippage or loosening. The spring rods extend into the mating grooves in stages, increasing the stability and reliability of the locking mechanism and reducing loosening caused by vibration or other factors. The threaded sleeve is fixed to the outer wall of the locking tube via a threaded connection, and the friction wheel presses against the limiting teeth, further enhancing the locking effect of the limiting teeth. This ensures that the entire reel device remains in the predetermined position during operation, preventing displacement due to misoperation or external forces. Attached Figure Description

[0030] Please see Figures 1-5 A label winding mechanism includes a base plate 1, a roll 101, a pressing and conveying mechanism, a roll clamping mechanism, and a clamping auxiliary mechanism. The pressing and conveying mechanism includes a hydraulic cylinder 2, a pressing frame 3, a longitudinal frame 4, a main wheel 5, a driven wheel 6, and a roller belt 7. The longitudinal frame 4 is fixedly installed on the top end of the base plate 1. The pressing frame 3 is slidably installed on the longitudinal frame 4, and the top end of the pressing frame 3 is connected to one end of the hydraulic cylinder 2 on the longitudinal frame 4. The main wheel 5 and the driven wheel 6 are rotatably installed on the pressing frame 3. The roller belt 7 connects the main wheel 5 and the driven wheel 6. The roll clamping mechanism... The structure includes a locking tube 8, a locking rod 9, a limiting tooth 10, a helical tooth plate 11, an insert plate 12, a rotating groove 13, and an annular groove 14. The locking rod 9 can extend into the locking tube 8. The limiting tooth 10 is rotatably mounted on the outer wall of the locking tube 8. The helical tooth plate 11 is rotatably mounted in the rotating groove 13 on the side wall of the locking tube 8. The insert plate 12 is mounted on one end of the helical tooth plate 11. Rotating the limiting tooth 10 drives the helical tooth plate 11 to rotate, so that the insert plate 12 extends into the annular groove 14 on the side wall of the locking rod 9, thereby fixing the locking rod 9 inside the locking tube 8.

[0031] In this embodiment, the longitudinal frame 4 is fixed to the base plate 1 to provide stable support. The pressure frame 3 moves up and down through the hydraulic cylinder 2, thereby adjusting the pressure. When the hydraulic cylinder 2 extends, the pressure frame 3 descends, pressing the label against the bottom support roller 23 to create a clamping effect. The main wheel 5 and the driven wheel 6 mounted on the pressure frame 3 are connected by a roller belt 7 to form a transmission system. The main wheel 5 is driven to rotate by the drive motor 24 on the side of the pressure frame 3. The main wheel 5 drives the roller belt 7 to rotate, and the roller belt 7 in turn drives the driven wheel 6 to rotate, achieving smooth delivery of the label. Throughout the process, the pressure and driving speed of the pressure frame 3 can be adjusted according to actual needs to ensure the label... To ensure the stability and consistency of the conveying process, the clamping tube 8 is fixed at the adjustment hole 20 of the base plate 1, and the clamping rod 9 is installed on the side plate 22. When fixing is required, the clamping rod 9 is inserted into the clamping tube 8. When the limiting tooth 10 rotates, it drives the helical tooth plate 11 to rotate in the rotating groove 13. The helical tooth plate 11 drives the embedded plate 12 to rotate and extend into the annular groove 14 on the side wall of the clamping rod 9, thus firmly locking the clamping rod 9 in the clamping tube 8. This allows the position of the reel to be selected among multiple adjustment holes 20 as needed, achieving flexible adjustment. The clamping tube 8 is connected to the adjustment hole 20 through the connecting plate 21, further enhancing the structural stability.

[0032] The snap-fit ​​auxiliary mechanism includes a base block 15, spring rods 16, a mating groove 17, a threaded sleeve 18, and a friction wheel 19. The base block 15 is installed at the bottom end of the limiting tooth 10. Multiple sets of spring rods 16 are installed on the outer wall of the snap-fit ​​tube 8. The mating groove 17 is opened on the base block 15. The rotation of the limiting tooth 10 drives the base block 15 to rotate, so that multiple spring rods 16 extend into the mating groove 17 step by step, so that the limiting tooth 10 is stably locked and rotated. The threaded sleeve 18 is threadedly connected to the outer wall of the snap-fit ​​tube 8. The friction wheel 19 is installed at the bottom end of the threaded sleeve 18. The threaded sleeve 18 pushes the friction wheel 19, so that the friction wheel 19 presses against the limiting tooth 10, so that the limiting tooth 10 is fixed in the rotation direction, thereby realizing the fixing of the embedded block in the annular groove 14.

[0033] In this embodiment, the reliability of the locking process is ensured by precisely controlling the rotation of the limiting tooth 10. The bottom block 15 is installed at the bottom of the limiting tooth 10 and rotates with the limiting tooth 10. When the bottom block 15 rotates, multiple sets of spring rods 16 on the outer wall of the locking tube 8 will extend into the mating groove 17 on the bottom block 15 in stages, forming a graded locking effect to ensure that the limiting tooth 10 can stably stay in a specific position during rotation. At the same time, the threaded sleeve 18 can be adjusted on the outer wall of the locking tube 8. The friction wheel 19 at the bottom applies controllable pressure to the limiting tooth 10 to further fix the rotation position of the limiting tooth 10. The design of the track 25 and the rail plate 26 provides good guidance for the bottom block 15 during rotation, reduces friction and improves running accuracy.

[0034] Please see Figures 1-5 As a supplementary embodiment of the label winding mechanism to the pressing and conveying mechanism, the roller clamping mechanism, and the clamping auxiliary mechanism: An adjustment hole 20 is provided on the base plate 1, and multiple sets of adjustment holes 20 are provided. A connecting plate 21 is installed at the bottom end of the side wall of the clamping tube 8, and the connecting plate 21 is fixed to the bottom end of the adjustment hole 20, so that the clamping tube 8 and the adjustment hole 20 are connected. A mounting bracket 501 is installed at the bottom end of the roller 101, and side plates 22 are installed at the bottom ends of both ends of the mounting bracket 501. The clamping rod 9 is installed on the side... The mounting bracket 501 is fixed in the required position by inserting the locking rod 9 into different adjustment holes 20 and locking it with the locking tube 8. The bottom support roller 23 is installed on the top end of the bottom plate 1, and the pressure frame 3 presses the label on the top end of the bottom support roller 23. The side of the pressure frame 3 is provided with a drive motor 24, and the drive motor 24 is connected to the main wheel 5. The top end of the connecting plate 21 is provided with a track 25, and the bottom end of the bottom block 15 is provided with a rail plate 26, and the rail plate 26 is rotated and guided on the track 25.

[0035] In summary, during the use or operation of the overall equipment: when the pressing conveyor mechanism needs to be operated, the longitudinal frame 4 is fixed on the base plate 1 to provide stable support. The pressing frame 3 moves up and down through the hydraulic cylinder 2, thereby adjusting the pressure. When the hydraulic cylinder 2 extends, the pressing frame 3 descends and presses the label against the bottom support roller 23, forming a clamping effect. The main wheel 5 and the driven wheel 6 installed on the pressing frame 3 are connected by the roller belt 7 to form a transmission system. The main wheel 5 is driven to rotate by the drive motor 24 on the side of the pressing frame 3. When the system is started, the main wheel 5 drives the roller belt 7 to rotate, and the roller belt 7 drives the driven wheel 6 to rotate, realizing the smooth conveying of the label. Throughout the process, the pressure and driving speed of the pressing frame 3 can be adjusted according to actual needs to ensure the stability and consistency of label conveying.

[0036] When the reel clamping mechanism is in operation, the clamping tube 8 is fixed at the adjustment hole 20 of the base plate 1, and the clamping rod 9 is installed on the side plate 22. When fixing is required, the clamping rod 9 is inserted into the clamping tube 8. When the limiting tooth 10 rotates, it drives the helical tooth plate 11 to rotate in the rotating groove 13. The helical tooth plate 11 drives the embedded plate 12 to rotate and extend into the annular groove 14 on the side wall of the clamping rod 9, thus firmly locking the clamping rod 9 in the clamping tube 8. This design allows the reel position to be selected among multiple adjustment holes 20 as needed, achieving flexible adjustment. The clamping tube 8 is connected to the adjustment hole 20 through the connecting plate 21, further enhancing the structural stability.

[0037] When the locking auxiliary mechanism is in operation, the reliability of the locking process is ensured by precisely controlling the rotation of the limiting tooth 10. The bottom block 15 is installed at the bottom of the limiting tooth 10 and rotates with the limiting tooth 10. When the bottom block 15 rotates, multiple sets of spring rods 16 on the outer wall of the locking tube 8 will extend into the mating groove 17 on the bottom block 15 in stages, forming a graded locking effect to ensure that the limiting tooth 10 can stably stay in a specific position during rotation. At the same time, the threaded sleeve 18 can be adjusted on the outer wall of the locking tube 8. The friction wheel 19 at the bottom applies controllable pressure to the limiting tooth 10 to further fix the rotation position of the limiting tooth 10. The design of the track 25 and the rail plate 26 provides good guidance for the bottom block 15 during rotation, reduces friction and improves running accuracy.
