[0002] Currently, as the width of the positive and negative electrode sheets of new energy lithium batteries increases, the length of the rubber rollers in the tension control system also needs to increase, and the structure of the tension isolation device becomes more complex. However, the service life of the rubber rollers is only 3-6 months, and since the weight of the rubber rollers also increases with the length of the rollers, it now exceeds the weight that two people can lift. Therefore, quick and convenient replacement of the rubber rollers has become a necessary consideration for lithium battery equipment. Utility Model Content

[0016] The following detailed description, in conjunction with the accompanying drawings, provides a specific embodiment of the quick-change rubber roller and tension interruption device of the present invention. This embodiment aims to clearly illustrate the components of the device, their interconnections, and its working principle to facilitate understanding and implementation.

[0017] like Figure 1 and Figure 2As shown, this utility model provides a quick-change rubber roller and tension interruption device, mainly including a rubber roller 1, a steel roller 2, a main frame, a rubber roller fixing bracket, a round rod guide rail 4, a rolling pulley 8, a lifting mechanism, and an adjustment mechanism. The rubber roller 1 is arranged parallel to the steel roller 2, which is fixedly installed on the main frame. The steel roller 2 is typically driven to rotate by a motor through a coupling, providing power for electrode transfer; while the rubber roller 1 is used to press against the steel roller 2 to interrupt the tension between the preceding and following electrode segments, and is a key component of the tension control system.

[0018] The rubber roller fixing bracket serves as the core frame supporting the rubber roller 1, and its specific structure is as follows: Figure 2 and Figure 3 As shown, it mainly consists of two parallel rubber roller fixing plates a3 and b6, which are firmly connected by at least one connecting rod 7 to form a stable overall frame structure. The rubber roller 1 is located within the area enclosed by the two rubber roller fixing plates and the connecting rod 7. To facilitate the easy removal of the rubber roller 1 assembly, two round rod guide rails 4 are fixedly installed on the main frame. Specifically, at the bottom of the rubber roller fixing plates a3 and b6, at least two rolling pulleys 8 are installed on the rubber roller fixing bracket. These rolling pulleys 8 are precisely supported on the round rod guide rails 4, allowing the entire rubber roller fixing bracket, along with the rubber roller 1 inside, to roll freely along the axial direction of the round rod guide rails 4. One end of the round rod guide rail 4 is provided with a docking interface for easy connection with a dedicated roller removal trolley. This allows the entire heavy rubber roller assembly to slide smoothly onto the trolley or slide from the trolley into the installation position when replacing the rubber roller, greatly saving manpower and improving efficiency.

[0019] The installation and lifting / tightening mechanism of the rubber roller 1 within the fixed bracket is as follows: Figure 4 As shown. Both ends of the rubber roller 1 are mounted in bearing seats 15 via bearings. Each bearing seat 15 is connected to a top block fixing plate 9 on its outer side. A top block 10 is fixedly installed at the bottom of the top block fixing plate 9. A T-slot is formed inside the top block 10, extending transversely through it. The lifting mechanisms are symmetrically arranged below both sides of the rubber roller fixing bracket. Each lifting mechanism includes a lifting cylinder 5, which is fixedly installed at the bottom of the main frame. A lifting insert 12 is provided at the top of the piston rod of the lifting cylinder 5. In normal operation, the piston rod of the lifting cylinder 5 extends, and when the rubber roller fixing bracket slides into the installation position, the lifting insert 12 slides into the T-slot of the top block. Because the T-slot has a margin of movement in its design, the lifting plug is not completely locked in the slot, but it can still lift the entire rubber roller 1 upward by pushing the top block 10 upward, and then by the top block fixing plate 9 and bearing seat 15, so that it is pressed onto the steel roller 2 with the required pressure, thus achieving the tension isolation function.

[0020] To ensure the stability and precision of the rubber roller assembly's movement during lifting and replacement, this device is equipped with a precise guiding and limiting structure. For example... Figure 4 As shown, a linear guide rail 11 is fixedly installed on the inner side of the rubber roller fixing plate b6, i.e., the side facing the rubber roller, and the top block fixing plate 9 is constrained on the slider of the linear guide rail 11. This design ensures that the top block fixing plate 9, together with the rubber roller 1, can only move smoothly in the vertical direction without swaying. At the same time, a first limiting block 13 is provided on the top block fixing plate 9, and a second limiting block (not labeled in the figure) is provided at a corresponding position on the rubber roller fixing plate b6. When the rubber roller needs to be replaced, the piston rod of the lifting cylinder 5 is fully retracted, and the lifting insert exits from the T-slot of the top block 10. At this time, the entire rubber roller assembly descends under its own gravity until the first limiting block 13 sits steadily on the second limiting block. This limiting design not only provides reliable support for the rubber roller assembly in the non-working state, but more importantly, it ensures that the lifting plug is completely disengaged from the T-slot of the top block 10 at this time, with sufficient clearance, such as about 5mm, at both the top and bottom, so that the lifting mechanism will not cause any interference when the rubber roller as a whole slides out along the guide rail.

[0021] In addition, to precisely control the gap between the rubber roller 1 and the steel roller 2 and prevent damage to the electrode sheets due to overpressure, this device also integrates a precision gap adjustment mechanism, the structure of which is as follows: Figure 5 As shown. This mechanism mainly includes a lead screw mechanism 17, an adjusting wedge 16, and an adjusting roller 14. The lead screw mechanism 17 is mounted on the main frame, and its lead screw can be rotated manually or by drive. The adjusting wedge 16, as the nut of the lead screw mechanism 17, can move back and forth along the lead screw axis as the lead screw rotates. The adjusting wedge 16 is located directly above the top block fixing plate 9, and its lower surface is machined into a continuous inclined surface. At the top of the top block fixing plate 9, the adjusting roller 14 is mounted via bearings, and the adjusting roller 14 always maintains contact with the inclined surface of the adjusting wedge 16. When the front and rear positions of the adjusting wedge 16 are adjusted by rotating the lead screw, the adjusting roller 14 will be displaced in the vertical direction due to the action of its inclined surface, thereby driving the entire top block fixing plate 9 and the rubber roller 1 to perform a slight lifting and lowering. This mechanism realizes stepless and precise adjustment of the gap between the rubber roller and the steel roller, providing flexible settings for different process requirements.

[0022] In summary, this invention achieves labor-saving and rapid assembly and disassembly of heavy-duty rubber rollers through the sliding cooperation of the rubber roller fixing bracket, rolling pulley, and round rod guide rail; it achieves reliable disengagement of the rubber rollers in the working state and the non-working state through the ingenious combination of the lifting cylinder and the top block with T-slot; it ensures the stability and accuracy of movement through the linear guide rail and the limiting block; and it achieves precise control of the gap between the rollers through the screw and wedge adjustment mechanism. The entire device has a reasonable structural design and is easy to operate, effectively solving the technical problem of difficult rubber roller replacement in large lithium battery electrode production equipment mentioned in the background art.
