Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to roller support mechanisms and rolling equipment. Background Technology

[0002] In roll sizing equipment, the rolls gradually wear down under long-term high-pressure, high-speed rolling contact, leading to decreased dimensional accuracy, uneven thickness of the pressed sheet, and poor surface finish, thus affecting product quality. Furthermore, rolls may develop fatigue cracks or spalling under cyclic stress, impacting rolling performance. When the rolls wear down to a certain extent, they need to be removed from the bearing housing for grinding or replacement. The bearing housing has a complex internal structure and cannot bear direct force; therefore, a pad is designed to be installed on the bearing housing. The force of the hydraulic cylinder acts on the pad, which then transmits the force to the bearing housing, thus driving the rolls up or down. However, because the entire roll system is close to the hydraulic cylinder, the pad must be removed first to ensure space for the unloading trolley before it can be inserted for disassembly.

[0003] In related technologies, existing pads are fixed to the bearing housing with screws. The screw holes are located directly below the bearing housing, which limits the operating space and makes it difficult to observe, resulting in difficult disassembly. In addition, the entire roller system is extremely heavy, and if the roller system is accidentally dropped during disassembly, the risk of it hitting someone's hand is extremely high.

[0024] In related technologies, existing pads are fixed to the bearing housing with screws. The screw holes are located directly below the bearing housing, which limits the operating space and makes it difficult to observe, resulting in difficult disassembly. In addition, the entire roller system is extremely heavy, and if the roller system is accidentally dropped during disassembly, the risk of it hitting someone's hand is extremely high.

[0025] To address the aforementioned issues, this application provides a roller support mechanism that facilitates the removal of the pad from the bearing housing by workers and improves safety.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 and Figure 2 The roller support mechanism includes a bearing housing 1, a pad 2, and a hydraulic cylinder 3. The bearing housing 1 is used to install and support the roller system. A groove 11 is formed on the bottom surface of the bearing housing 1. The groove 11 is recessed upward from the bottom surface of the bearing housing 1, thereby preventing the groove 11 from occupying the space between the bearing housing 1 and the hydraulic cylinder 3. The pad 2 is detachably installed in the groove 11 and is located directly below the groove 11.

[0028] See Figure 1-3 The pad 2 can slide along the extension direction of the groove 11, which extends from one side of the bearing seat 1 along the bottom surface of the bearing seat 1. In one embodiment, the groove 11 extends from one side of the bearing seat 1 to the opposite side. In another embodiment, the groove 11 extends from one side of the bearing seat 1 to the middle of the bottom surface of the bearing seat 1. The hydraulic cylinder 3 is located below the bearing seat 1, and there is a gap between the hydraulic cylinder 3 and the bearing seat 1. The pad 2 is embedded in the gap between the hydraulic cylinder 3 and the bearing seat 1. The hydraulic cylinder 3 is located below the pad 2 and supports the pad 2. When the hydraulic cylinder 3 rises, it supports the bearing seat 1 through the pad 2. The hydraulic cylinder 3 can lift upward or lower downward. When the hydraulic cylinder 3 lifts upward, it applies force to the pad 2, which transmits the force to the bearing seat 1, thereby causing the roller system in the bearing seat 1 to lift or lower.

[0029] See Figure 1-3 In actual use, when it is necessary to remove the roll 4 from the bearing housing 1, the operator can pull the pad 2 out from between the bearing housing 1 and the hydraulic cylinder 3 along the extension direction of the slide groove 11. After the pad 2 is completely separated from the bearing housing 1, the roll unloading trolley is inserted into the gap between the bearing housing 1 and the hydraulic cylinder 3. The roll unloading trolley disassembles the roll system. After replacing the roll system, the pad 2 is slid into the gap between the bearing housing 1 and the hydraulic cylinder 3 along the extension direction of the slide groove 11.

[0030] This application provides a groove 11 on the bottom surface of the bearing housing 1, allowing the pad 2 to be detachably installed in the groove 11. By sliding the pad 2 along the extension direction of the groove 11, the pad 2 can be assembled onto or removed from the bearing housing 1. The assembly of the pad 2 and the bearing housing 1 does not require the use of bolts or pins, simplifying the structure and reducing the risk of loosening. Furthermore, the pad 2 can slide in a specific direction, meeting installation requirements while improving overall safety performance.

[0031] See Figure 1-4 The extension direction of the chute 11 is the same as the axial direction of the roller system on the bearing seat 1, so that the direction in which the unloading trolley enters the gap between the bearing seat 1 and the hydraulic cylinder 3 is the same as the extension direction of the chute 11. Only an opening needs to be left between the bearing seat 1 and the hydraulic cylinder 3 to replace the pad 2 or the unloading trolley.

[0032] See Figure 2-5 The bearing housing 1 is provided with a support structure, which is detachably connected to the pad 2. The support structure supports the pad 2 and prevents the pad 2 from falling. When the worker needs to remove the pad 2 from the bottom surface of the bearing housing 1, the worker pulls the pad 2 along the extension direction of the slide groove 11. As the pad 2 slides along the slide groove 11, the support structure maintains its support for the pad 2 until the pad 2 is completely detached from the bearing housing 1. By supporting the pad 2 through the support structure, the worker is prevented from being injured or having their hands pinched due to careless operation during the removal of the pad 2, thereby improving safety.

[0033] In some embodiments, the supporting structure is an L-shaped bracket, with an L-shaped bracket at the bottom of each of the opposite sides of the bearing seat 1. The bottom of the two L-shaped brackets supports the bottom surface of the pad 2, thereby keeping the pad 2 balanced and preventing it from falling off the L-shaped bracket during sliding relative to the bearing seat 1.

[0034] See Figure 2-5 In some embodiments, the slide groove 11 is a dovetail groove, and the pad 2 is provided with a dovetail groove strip 21. The dovetail groove strip 21 is fitted into the slide groove 11, and the dovetail groove strip 21 slides along the extension direction of the slide groove 11. Since the slide groove 11 is a dovetail groove, the dovetail groove can support the dovetail groove strip 21. That is, the slide groove 11 can serve as a support structure, thereby ensuring that when the pad 2 slides along the slide groove 11, the slide groove 11 can lift the pad 2 until the pad 2 is completely separated from the bearing seat 1. The friction force of the inclined surface of the dovetail groove can be used to fix the slide groove 11 and the pad 2 without the need for bolts or pins, simplifying the structure and reducing the risk of loosening. The installation is more convenient and easier to observe. The dovetail groove structure of the slide groove 11 can also be used to prevent the pad 2 from detaching in the vertical direction.

[0035] See Figure 3-5To facilitate the worker in pulling the pad 2 out of the gap between the bearing housing 1 and the hydraulic cylinder 3, the pad 2 is provided with a gripping part 22. When the worker needs to pull the pad 2 out of the gap between the bearing housing 1 and the hydraulic cylinder 3, the worker can grab the gripping part 22 and pull the pad 2 out along the extension direction of the slide groove 11.

[0036] In some embodiments, the gripping part 22 is a handle, and the gripping part 22 is located on the side of the pad 2. The operator can pull the gripping part 22 from the side of the pad 2 to pull the pad 2 out from the gap between the bearing seat 1 and the hydraulic cylinder 3.

[0037] See Figure 2-5 In some embodiments, the gripping part 22 is a groove, recessed downward from the upper surface of the pad 2. When the worker needs to pull the pad 2 out of the gap between the bearing seat 1 and the hydraulic cylinder 3, they can put their hand into the gap between the bearing seat 1 and the hydraulic cylinder 3 and insert their fingers into the groove to push the groove and pull the pad 2 out of the gap between the bearing seat 1 and the hydraulic cylinder 3. This design avoids the gripping part 22 occupying the internal space of the roller support mechanism. The pad 1 is provided with a mounting part, which is installed in the slide groove 11. When the mounting part slides along the extension direction of the slide groove 11, the entire pad 1 slides along the extension direction of the slide groove 11. Preferably, the mounting part is a dovetail groove 21, and there are at least two gripping parts 22. The dovetail groove 21 is located between at least two gripping parts 22, thereby avoiding the dovetail groove 21 from hindering the worker from putting their hand into the gripping part 22. Specifically, the gripping part 22 is located in the extension direction of the dovetail groove 21.

[0038] See Figure 1-3 In some embodiments, the bearing housing 1 is provided with a stop portion 12, which is disposed on the bottom surface of the bearing housing 1 and located in the sliding direction of the dovetail groove 21. The stop portion 12 is used to limit the dovetail groove 21. When the operator pushes the pad 2 into the gap between the bearing housing 1 and the hydraulic cylinder 3 along the extension direction of the slide groove 11, the stop portion 12 can prevent the pad 2 from excessively displacing and colliding with other components. In addition, when the pad 2 abuts against the stop portion, the side of the pad 2 is flush with the side of the bearing housing 1 and the pad 2 is located directly below the bearing housing 1. The stop portion 12 can also play a role in positioning the pad 2. In some embodiments, the stop portion 12 is the inner sidewall of the slide groove 11. When the dovetail groove 21 slides to the end of the slide groove 11, the dovetail groove 21 abuts against the stop portion 12. In some embodiments, the stop portion 12 is a baffle. The stop portion 12 is located at the edge of the bottom surface of the bearing seat 1 and faces the pad 2. When the pad 2 slides a certain distance into the gap between the bearing seat 1 and the cylinder 3, the side of the pad 2 will be blocked by the stop portion 12, thereby restricting the pad 2 from continuing to slide.

[0039] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a roller pressing device and corresponding embodiments.

[0040] See Figure 1-5 The roller pressing equipment includes a roller system and a roller system support mechanism. The roller system includes rolls 4, which are mounted on bearing seats 1 via bearings. The roller system support mechanism includes bearing seats 1, a pad 2, and a hydraulic cylinder 3. A groove 11 is provided on the bottom surface of the bearing seat 1, which is recessed upward from the bottom surface of the bearing seat 1. The pad 2 is detachably installed in the groove 11 and is located directly below the groove 11. The pad 2 can slide along the extension direction of the groove 11, which extends from one side of the bearing seat 1 along the bottom surface of the bearing seat 1. The hydraulic cylinder 3 is located below the bearing seat 1, and there is a gap between the hydraulic cylinder 3 and the bearing seat 1. The pad 2 is embedded in the gap between the hydraulic cylinder 3 and the bearing seat 1. The hydraulic cylinder 3 is located below the pad 2, supports the pad 2, and supports the bearing seat 1 through the pad 2.
