Description

Technical Field

[0001] This utility model relates to the field of roller equipment technology, and in particular to a roller device for correcting roller speed. Background Technology

[0002] The separator is a key material used in lithium-ion batteries. During the separator manufacturing process, the linear velocity of the separator surface and the linear velocity of the roller surface may differ when the separator is transported by an electric roller. This difference can cause the separator to slip on the electric roller, and this speed difference cannot be fed back to the operator. Currently, most manufacturers use servo motors to drive the roller rotation, but this type of device has several drawbacks: it cannot provide feedback on the speed difference between the electric roller and the separator surface, it cannot accurately adjust the roller surface speed, leading to membrane slippage, and the roller shaft is connected by bearing housings, which can easily cause the roller shaft to loosen when the bolts come loose, affecting the stability of the roller shaft rotation. Therefore, we propose a roller device for correcting the roller speed to solve the above problems. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a roller device for correcting roller speed.

[0027] Reference Figure 1-4 A roller device for correcting roller speed includes an electric roller assembly 1, a bearing housing assembly 2, and a static torque sensor 301. The electric roller assembly 1 is disposed between two bearing housing assemblies 2. The electric roller assembly 1 includes an electric roller shaft 101 and an electric roller 102. The electric roller shaft 101 is rotatably mounted between the two bearing housing assemblies 2, and the electric roller 102 is mounted on the electric roller shaft 101. A membrane 4 for transmission is mounted on the electric roller 102. The static torque sensor 301 is installed at one end of the electric roller shaft 101, and the static torque sensor 301 has a sensor output wire 302. The static torque sensor 301 is installed at the other end of the electric roller shaft 101. It can detect and output the torsional force when the electric roller shaft rotates at any time. More specifically, the torque value can be set according to the required tension of the roller on the membrane 4, and then the speed can be corrected by comparing the output value fed back by the static torque sensor 301 with the set torque value. This ensures that the linear speed of the electric roller 102 is the same as the linear speed of the membrane 4, and avoids the membrane 4 slipping on the roller surface.

[0028] In this embodiment, the other end of the electric roller shaft 101 is used to install the electric roller control power line 103, which is used to control the rotation speed of the electric roller 102.

[0029] In this embodiment, the bearing housing assembly 2 includes a lower bearing housing 201 and an upper bearing housing 203. The upper bearing housing 203 is mounted on the corresponding lower bearing housing 201, and a disassembly and assembly mechanism is provided between the upper bearing housing 203 and the lower bearing housing 201. A bearing 204 is mounted on the electric roller shaft 101, and the bearing 204 is installed between the lower bearing housing 201 and the upper bearing housing 203. The disassembly and assembly mechanism includes a lower threaded sleeve 501, an upper threaded sleeve 502, and a fixing bolt 503. The lower threaded sleeve 501 is fixedly installed on both the front and rear sides of the lower bearing housing 201, and the upper threaded sleeve 502 is fixedly installed on both the front and rear sides of the upper bearing housing 203. A fixing bolt 503 is threaded between the upper threaded sleeve 502 and the corresponding lower threaded sleeve 501. The fixing bolt 503 can fix and release the two threaded sleeves, thereby achieving the purpose of assembling and disassembling the upper bearing housing 203 and the lower bearing housing 201, and the purpose of disassembling and assembling the electric roller shaft 101 from the bearing housing assembly 2.

[0030] In this embodiment, the lower shaft seat 201 is provided with a mounting hole 202, and a locking bolt for fixing the lower shaft seat 201 is provided in the mounting hole 202. By providing the locking bolt, the purpose of disassembling and assembling the lower shaft seat 201 can be achieved.

[0031] In this embodiment, a positioning groove 601 is provided on the top of the lower shaft seat 201, and a positioning seat 602 is fixedly installed on the bottom of the upper shaft seat 203. The positioning seat 602 is adapted to the corresponding positioning groove 601. A moving hole 702 is provided on one side of the positioning groove 601. The moving hole 702 is connected to the corresponding lower threaded sleeve 501. A plug rod 703 is slidably installed in the moving hole 702. One end of the plug rod 703 is set as a hemisphere. A slot 701 is provided on one side of the positioning seat 602. The other end of the plug rod 703 is adapted to the corresponding slot 701. Sliding grooves 801 are provided on the top and bottom inner walls of the moving hole 702. Sliding seats 802 are fixedly installed on the top and bottom of the plug rod 703.

[0032] In this invention, a motor roller control power line is installed at the other end of the electric roller shaft 101. This power line can control the rotation speed of the electric roller 102. A static torque sensor 301 is installed at one end of the electric roller shaft 101, which can detect and output the torsional force when the electric roller shaft rotates. When the linear speeds of the roller and the membrane 4 are different, the electric roller shaft 101 will rotate and receive feedback through the static torque sensor. Then, the rotation speed is corrected by comparing the output value of the static torque sensor 301 with the set torque value. The bearing 204 on the electric roller 102 is placed on the lower shaft seat 201, and the upper shaft seat 203 is installed on the lower shaft seat 201. At this time, the positioning seat 602 can be inserted into the corresponding positioning groove 601, which can realize the upper... The purpose of positioning the bearing seat 203 is to install the fixing bolt 503 threaded into the upper threaded sleeve 502 and the lower threaded sleeve 501, thereby fixing the upper bearing seat 203 and the lower bearing seat 201. This facilitates the disassembly and assembly of the electric roller 102. The fixing bolt 503 is screwed into the lower threaded sleeve 501, which can compress the insert rod 703, allowing the insert rod 703 to move. The insert rod 703 can drive the sliding seat 802 and compress the return spring 803. The movement of the insert rod 703 can enter and exit the slot 701. Through the reinforcement of the insert rod 703 and the slot 701, the loosening of the fixing bolt 503 can be prevented, thus avoiding the loosening of the upper bearing seat 203 and the lower bearing seat 201.
