Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine tension control mechanism. Background Technology

[0002] A coating machine is a device used to uniformly coat a slurry onto a substrate. It is widely used in the lithium battery manufacturing industry. In lithium battery production, the coating machine is mainly used to uniformly coat the positive and negative electrode slurries onto the metal current collector to form the positive and negative electrode sheets of the battery. The working principle of the coating machine is to precisely control the flow rate, coating speed and tension of the slurry to uniformly coat the slurry onto the substrate. After coating, the substrate will undergo drying and curing treatment to ensure that the slurry is completely adhered to the surface of the substrate.

[0003] Existing coating machines cannot achieve auxiliary tension control during use. Operators need to manually adjust the position of the tension roller to adjust the tension of the output material. This method of tension control cannot maintain accuracy and reduces production efficiency. Therefore, a tension control mechanism for coating machines is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a tension control mechanism for a coating machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coating machine tension control mechanism, comprising a device body, a symmetrical limiting groove provided on the side of the device body, a movable block installed in the limiting groove, symmetrical limiting blocks installed on the side of the movable block, a rotating shaft installed on the side of the movable block, an adjusting roller installed at one end of the rotating shaft, a movable groove provided in the movable block, a slider installed at one end of the movable groove, symmetrical pressure sensors installed on the side of the slider, a main control box installed at one end of the device body, a drive motor installed on the side of the device body, a lead screw installed at one end of the drive motor, and a connecting block installed at one end of one of the limiting blocks.

[0006] Preferably, the movable groove is provided with two pressure sensors, one end of which is installed on the inner wall of the movable groove, and the other end of which is installed on the slider.

[0007] Preferably, multiple transmission rollers are rotatably mounted inside the main body of the device, and the adjusting roller is rotatably mounted on a rotating shaft.

[0008] Preferably, the movable block is slidably installed in the limiting groove, and one end of the connecting block is threadedly connected to the lead screw.

[0009] Preferably, one end of the rotating shaft is rotatably mounted inside the slider, and one end of the slider is equipped with symmetrical springs.

[0010] Preferably, one end of the pressure sensor is electrically connected to the main control box, and the lead screw is mounted on the output end of the drive motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model sets up a pressure sensor and a main control box, etc. The pressure sensor is installed in the movable block on the side of the adjusting roller, which can monitor the raw material during transmission. The monitoring results are transmitted to the main control box, and the results are analyzed and processed by the main control box. The drive motor is started to adjust the screw to rotate, and the connecting block is moved by the screw. The connecting block drives the movable block to slide in the limit groove, thereby adjusting the adjusting roller to move up and down. The angle between the adjusting roller and the raw material is adjusted to meet the accurate adjustment of tension.

[0013] (2) By setting up an adjusting roller and spring, when one end of the adjusting roller is transmitting raw materials, the slider at one end of the adjusting roller can slide in the movable groove and compress the spring to a certain extent. The rebound of the spring enables the adjusting roller to absorb small vibrations when rotating, thus achieving a buffering effect, realizing self-adjustment, reducing interference, and improving the applicability of the main body of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1This utility model provides a technical solution: a tension control mechanism for a coating machine, comprising a main body 1, symmetrical limiting grooves 2 on the side of the main body 1, a movable block 3 installed in the limiting groove 2, symmetrical limiting blocks 4 installed on the side of the movable block 3, a rotating shaft 5 installed on the side of the movable block 3, an adjusting roller 6 installed at one end of the rotating shaft 5, a movable groove 7 inside the movable block 3, a slider 8 installed at one end of the movable groove 7, symmetrical pressure sensors 9 installed on the side of the slider 8, a main control box 10 installed at one end of the main body 1, a drive motor 11 installed on the side of the main body 1, a lead screw 12 installed at one end of the drive motor 11, a connecting block 13 installed at one end of one limiting block 4, two pressure sensors 9 inside the movable groove 7, one end of the pressure sensor 9 installed on the inner wall of the movable groove 7, and the other end of the pressure sensor 9 installed on the slider 8, multiple transmission rollers 15 rotatably mounted inside the main body 1, the adjusting roller 6 rotatably mounted on the rotating shaft 5, and one end of the pressure sensor 9 connected to the main control box 10. Electrically connected, the lead screw 12 is mounted on the output end of the drive motor 11. When the coating machine is running, the tension of the raw material needs to be adjusted. The raw material is transmitted through multiple transmission rollers 15. When the raw material is transmitted in the main body 1, one end of the raw material abuts against the side of the adjusting roller 6. A pressure sensor 9 is installed in the movable block 3 on the side of the adjusting roller 6. When the adjusting roller 6 is stretched and squeezed, one end of the rotating shaft 5 slides in the movable groove 7 through the slider 8. The pressure sensor 9 monitors the pressure of the raw material during transmission by the adjusting roller 6. The data is transmitted to the main control box 10 according to the monitoring results. The results are analyzed and processed by the preset programming of the main control box 10. The drive motor 11 is started to drive the lead screw 12 to rotate. The lead screw 12 moves the connecting block 13, which in turn drives the movable block 3 to slide up and down along the limiting groove 2 under the limit of the limiting block 4. This causes the adjusting roller 6 to move up and down. The angle between the adjusting roller 6 and the raw material is adjusted to accurately adjust the tension and ensure that the pressure during transmission is within the preset range.

[0023] Example 2: As Figure 3 and 4 As shown, one end of the rotating shaft 5 is rotatably mounted inside the slider 8, and one end of the slider 8 is equipped with symmetrical springs 14. When the adjusting roller 6 transmits raw materials, it may generate a certain vibration. At this time, the slider 8 mounted on the rotating shaft 5 can slide in the movable groove 7 to compress or stretch the two springs 14 to a certain extent. Through the rebound of the springs 14, the adjusting roller 6 can absorb small vibrations when rotating, play a buffering role, realize self-adjustment, and improve the applicability of the main body 1 of the device. The remaining features are the same as in Embodiment 1.

[0024] The working principle is as follows: When the coating machine is running, the tension of the raw material needs to be adjusted. Multiple drive rollers 15 transmit the raw material. During transmission in the main body 1, one end of the raw material abuts against the side of the adjusting roller 6. A pressure sensor 9 is installed in the movable block 3 on the side of the adjusting roller 6. When the adjusting roller 6 is stretched or compressed, one end of the rotating shaft 5 slides in the movable groove 7 via the slider 8. The pressure sensor 9 monitors the pressure of the raw material during transmission by the adjusting roller 6. Based on the monitoring results, the data is transmitted to the main control box 10. The main control box 10 analyzes and processes the results through its preset programming, starts the drive motor 11 to drive the lead screw 12 to rotate, and transmits the material through the lead screw 12 to the main control box 10 ... The lever 12 moves the connecting block 13, which in turn drives the movable block 3 to slide up and down along the limiting groove 2 under the limitation of the limiting block 4. This, in turn, moves the adjusting roller 6 up and down, adjusting the angle between the adjusting roller 6 and the raw material to accurately adjust the tension and ensure that the pressure during transmission is within the preset range. When the adjusting roller 6 transmits the raw material, it may generate some vibration. At this time, the slider 8 installed on the rotating shaft 5 can slide in the movable groove 7, compressing or stretching the two springs 14. Through the rebound of the springs 14, the adjusting roller 6 can absorb small vibrations during rotation, playing a buffering role and achieving self-adjustment, thus improving the applicability of the main body 1 of the device.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
