Description

Technical Field

[0001] This utility model relates to the field of roller repair and disassembly technology, and more specifically, to a tooling for repairing and disassembling PRS rollers in a diaphragm production line. Background Technology

[0002] In the continuous production of polymer film materials such as lithium-ion battery separators, the PRS roller, as the core transmission and support component of the production line, plays a crucial role in the conveying, tensioning, and shaping of the separator. Its operational stability and precision directly determine the thickness uniformity, surface smoothness, and production continuity of the separator product. Because the production line operates under high speed, continuous load, and potentially dusty conditions for extended periods, the bearings, shafts, and roller surfaces of the PRS roller are prone to wear, deformation, or damage, requiring periodic shutdowns for disassembly, maintenance, or replacement.

[0003] However, in actual use, there is a significant problem with the maintenance and disassembly of PRS rollers: the installation spacing and position of the two rotating shafts differ between different production lines or different workstations on the same production line; moreover, the rollers themselves have a certain weight, and manual handling and disassembly are not only labor-intensive and inefficient, but also pose safety hazards; and existing disassembly tools (such as lifting tools and pullers) are usually fixed in structure or have a single function, with extremely poor versatility. This forces the maintenance department to customize special disassembly tools for each type of roller, which not only significantly increases tool manufacturing and management costs, but also greatly extends equipment downtime due to tool preparation and replacement, failing to meet the stringent requirements of modern production for maintenance efficiency and economy.

[0004] Therefore, in order to solve the problem of poor versatility and insufficient adaptability of disassembly tools in the above-mentioned prior art, resulting in low efficiency, this utility model proposes a PRS roller maintenance and disassembly tooling for diaphragm production lines as a further improvement. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a PRS roller maintenance and disassembly tooling for a diaphragm production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tooling for repairing and disassembling PRS rollers in a diaphragm production line, comprising: The main body of the tooling rod is parallel to the roller. A connecting sleeve rod is movably sleeved on the end of the tooling rod body, and a fixing mechanism is provided between the connecting sleeve rod and the tooling rod body; A support frame, the bottom of which is fixedly connected to the side of the connecting sleeve rod, and the support frame and the connecting sleeve rod are perpendicular to each other; A connecting frame, which is perpendicular to both the connecting sleeve rod and the support frame, and whose two ends are fixedly connected to the tops of the two support frames, respectively; and, The top of the hoisting frame is slidably connected to the connecting frame via a sliding mechanism.

[0007] Furthermore, the sliding mechanism includes: a sliding limiting member and a limiting groove; The limiting groove is formed inside the connecting frame and along the length of the connecting frame. The sliding limiting member slides on the inner wall of the limiting groove. The bottom of the sliding limiting member passes through the connecting frame and is fixedly connected to the top of the hoisting frame. A sliding groove is formed between the limiting groove and the lower surface of the connecting frame. The sliding groove is used for the sliding limiting member to slide.

[0008] Furthermore, a second fixing bolt is provided on the connecting frame, which is threadedly engaged with the sliding limit member. By tightening the second fixing bolt, its end is pressed against the connecting frame, thereby locking and fixing the sliding limit member. An upper sliding groove is provided between the limiting groove and the upper surface of the connecting frame, which is used for the second fixing bolt to slide.

[0009] Furthermore, the fixing mechanism includes: a first screw hole on the end face of the tooling rod body and a second screw hole on the end face of the connecting sleeve rod. The connecting sleeve rod has a sleeve groove inside. The end of the tooling rod body is inserted into the sleeve groove. The sleeve groove communicates with the second screw hole. Both the first screw hole and the second screw hole are threaded with a first fixing bolt.

[0010] Furthermore, the cross-section of the sliding limiting member is T-shaped.

[0011] Furthermore, the lifting frame is made of channel steel with an I-shaped cross-section.

[0012] Furthermore, the two tooling rod bodies are distributed on both sides of the roller radially, and both ends of the tooling rod bodies are movably connected to connecting sleeve rods, and at least two of the support frames are fixedly connected to the side of one of the connecting sleeve rods.

[0013] Furthermore, the tops of the multiple support frames located at the same end of the tooling rod body are all fixedly connected by connecting rods.

[0014] Furthermore, reinforcing ribs are installed between the support frame and the adjacent connecting frame to construct a triangular structure.

[0015] Furthermore, the tooling is constructed from channel steel and profiles to form a lightweight truss structure, suitable for manual handling and disassembly of PRS rollers in diaphragm production lines.

[0016] The technical effects and advantages of this utility model are as follows: 1. Compared with existing technologies, by setting up connecting sleeves, support frames, connecting frames, and connecting rods, when it is necessary to disassemble the rollers of the production line, two connecting sleeves are installed on the main body of the tooling rod using a fixing mechanism, and hoisted above the rollers. By installing a hoisting hoist on the hoisting frame and connecting the hoisting hoist to the rotating shaft on the roller, the rotating shaft and the hoisting frame are connected through two hoists, which facilitates the subsequent lifting of the main body of the tooling rod as a whole, thereby realizing the disassembly and maintenance of the rollers without the need for operation on the production equipment. This avoids manual knocking, prying, and other operations on the equipment frame, and avoids secondary damage such as scratches or deformation to the precision roller rotating shaft, bearing seats, and even the equipment frame itself. Moreover, it is compatible with the disassembly needs of various specifications of PRS rollers, thereby effectively reducing maintenance costs, shortening downtime, improving the safety and standardization of disassembly operations, and improving maintenance efficiency.

[0017] 2. Compared with existing technologies, by setting up a sliding mechanism, it is easy to adjust the placement position of the hoisting frame. When the adjustment is completed, it is fixed by the second fixing bolt, thereby achieving the effect of lateral adjustment. It enables a set of tooling to quickly and accurately adapt to the disassembly requirements of various PRS rollers of different specifications and to the hoisting of shafts in different positions, thus improving the applicability of the tooling rod body.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 The illustrated PRS roller maintenance and disassembly fixture for a diaphragm production line includes: The tooling rod body 10 is parallel to the roller 80. A connecting sleeve 20 is movably sleeved on the end of the tooling rod body 10, and a fixing mechanism 30 is provided between the connecting sleeve 20 and the tooling rod body 10. The support frame 40 is fixedly connected at its bottom to the side of the connecting sleeve rod 20, and the support frame 40 and the connecting sleeve rod 20 are perpendicular to each other. The connecting frame 50 is perpendicular to both the connecting sleeve 20 and the support frame 40, and both ends of the connecting frame 50 are fixedly connected to the tops of the two support frames 40 respectively; and, The top of the hoisting frame 60 is slidably connected to the connecting frame 50 via a sliding mechanism 70.

[0025] When the roller 80 needs to be disassembled, multiple connecting sleeves 20 are fitted onto the tooling rod body 10, and the connecting sleeves 20 are fixedly connected to the tooling rod body 10 using the fixing mechanism 30, thus completing the assembly of the maintenance and disassembly tooling of this application. Since the roller 80 has a rotating shaft 90 installed inside, a hoist needs to be installed on the hoisting frame 60, and one end of the hoist is connected to the rotating shaft 90. That is, the hoisting frame 60 and the rotating shaft 90 on the roller 80 are connected by two hoists to make them stable after installation. By lifting the tooling rod body 10, the hoisting frame 60 is also lifted, thereby driving the rotating shaft 90 to be lifted, so that the roller 80 can be taken out of the equipment for subsequent maintenance and replacement.

[0026] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the sliding mechanism 70 includes: a sliding limit member 71 and a limit groove 72; The limiting groove 72 is formed inside the connecting frame 50 and along the length of the connecting frame 50. The sliding limiting member 71 slides on the inner wall of the limiting groove 72. The bottom of the sliding limiting member 71 passes through the connecting frame 50 and is fixedly connected to the top of the hoisting frame 60. A sliding groove 73 is formed between the limiting groove 72 and the lower surface of the connecting frame 50. The sliding groove 73 is used for the sliding limiting member 71 to slide. So that the sliding limiting member 71 slides on the inner wall of the limiting groove 72 and drives the hoisting frame 60 to slide laterally.

[0027] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, a second fixing bolt 51 is provided on the connecting frame 50. The second fixing bolt 51 is threadedly engaged with the sliding limit member 71. By tightening the second fixing bolt 51, its end is pressed against the connecting frame 50, thereby locking and fixing the sliding limit member 71. An upper sliding groove 52 is provided between the limiting groove 72 and the upper surface of the connecting frame 50. The upper sliding groove 52 is used for the second fixing bolt 51 to slide. In order to lock and fix the sliding limit member 71 that slides on the inner wall of the limiting groove 72 using the second fixing bolt 51, when adjusting the placement position of the hoisting frame 60, after sliding the hoisting frame 60 to a suitable position, the second fixing bolt 51 can be rotated so that the second fixing bolt 51 continuously rotates into the threaded hole 711 opened on the sliding limit member 71. When the end of the second fixing bolt 51 is pressed against the upper surface of the connecting frame 50, the position of the sliding limit member 71 can be fixed, thereby fixing the position of the hoisting frame 60, achieving the effect of lateral adjustment, and adapting to the hoisting of the rotating shaft 90 in different positions.

[0028] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the fixing mechanism 30 includes: a first screw hole 31 opened on the end face of the tooling rod body 10 and a second screw hole 32 opened on the end face of the connecting sleeve rod 20. The connecting sleeve rod 20 has a sleeve groove 21 inside. The end of the tooling rod body 10 is inserted into the sleeve groove 21. The sleeve groove 21 communicates with the second screw hole 32. The first screw hole 31 and the second screw hole 32 are both threaded with a first fixing bolt 33. In order to keep the positions of the first screw hole 31 and the second screw hole 32 consistent, the first fixing bolt 33 is turned into the first screw hole 31 and the second screw hole 32, so that the connecting sleeve rod 20 is fixed on the tooling rod body 10, and the assembly of the tooling rod body 10 is completed, that is, the assembly of the maintenance and disassembly tooling of this application is completed.

[0029] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the cross-section of the sliding limit member 71 is T-shaped; this shape facilitates positioning and prevents it from falling off.

[0030] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the hoisting frame 60 is made of channel steel with an I-shaped cross-section, so that the hoisting hoist can be installed on the hoisting frame 60 more conveniently.

[0031] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, two tooling rod bodies 10 are distributed on both sides of the roller 80 radially. Both ends of the tooling rod body 10 are movably connected to the connecting sleeve rod 20. At least two support frames 40 are fixedly connected to the side of one connecting sleeve rod 20. By utilizing the movable connection between the connecting sleeve rod 20 and the tooling rod body 10, and by utilizing the convenience of fixing mechanism 30, the installation and disassembly of both are relatively convenient, thereby improving the efficiency of maintenance work.

[0032] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the tops of multiple support frames 40 located at the same end of the tooling rod body 10 are all fixedly connected by connecting rods 53 in order to improve the load-bearing capacity of the overall structure.

[0033] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, reinforcing ribs are installed between the support frame 40 and the adjacent connecting frame 50 to construct a triangular structure; in order to utilize the principle of triangular stability to improve load stability.

[0034] In a preferred embodiment, as shown in the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the tooling is a lightweight truss structure welded from channel steel and profiles, suitable for manual handling and disassembly of PRS rollers in diaphragm production lines; considering that the weight of roller 80 is fixed, the tooling of this application is designed to withstand a working load of no more than 0.5 tons.

[0035] The working principle of this utility model is as follows: When it is necessary to disassemble the roller 80, multiple connecting sleeves 20 are sleeved on the tooling rod body 10 through the sleeve groove 21 of the connecting sleeve 20. The positions of the first screw hole 31 on the tooling rod body 10 and the second screw hole 32 on the connecting sleeve 20 are aligned. The first fixing bolt 33 is turned into the first screw hole 31 and the second screw hole 32, so that the connecting sleeve 20 is fixed on the tooling rod body 10, thus completing the assembly of the tooling rod body 10. The hoist is installed on the hoisting frame 60, and the other end of the hoist is connected to the rotating shaft 90 on the roller 80. The two hoists are used to connect the tool rod body 10 and the rotating shaft 90 to make it stable after installation. The tool rod body 10 is lifted to drive the rotating shaft 90 out of the equipment for easy maintenance and replacement. When adjusting the position of the hoisting frame 60, it can slide within the sliding limit piece 71 and the limit groove 72, causing the second fixing bolt 51 to slide simultaneously. This adjusts the placement position of the hoisting frame 60. After the hoisting frame 60 is slid to the appropriate position, the second fixing bolt 51 can be rotated, causing it to continuously rotate into the threaded hole 711. When the end of the second fixing bolt 51 abuts against the upper surface of the connecting frame 50, the position of the sliding limit piece 71 can be fixed, thereby fixing the position of the hoisting hoist to be assembled on the hoisting frame 60, achieving the effect of lateral adjustment. This adapts to the hoisting of the rotating shaft 90 in different positions. By turning out the first fixing bolt 33, the assembled tooling rod body 10 and connecting sleeve rod 20 can also be disassembled. Each component of the tooling can be stored and transported separately, reducing storage and handling difficulties and improving applicability.
