Detailed Implementation

[0016] 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.

[0017] Example 1: Please see Figure 1-5 This utility model provides a technical solution: a tension roller structure for a glass fiber warping machine, including a base 1, a portal frame 11 fixedly connected to the top surface of the base 1, a movable plate 2 slidably disposed between the inner walls of the portal frame 11, connecting blocks 21 fixedly connected to both sides of the bottom surface of the movable plate 2, and movable blocks 3 slidably disposed on the bottom of each of the two connecting blocks 21 close to each other, a rotating shaft 41 disposed between the two connecting blocks 21, a rotating roller 4 fixedly connected to the outer periphery of the rotating shaft 41, bearings 42 installed at both ends of the rotating shaft 41, and the connecting block 21 and the movable plate 3 located on one side of the roller 41 are also included. Block 3 engages with the corresponding bearing 42. During operation, the moving plate 2 is moved, which drives the rotating roller 4, rotating shaft 41, and bearing 42 to move. The rotating roller 4 comes into contact with the material. During production, the operator can adjust the pressure of the rotating roller 4 according to the actual situation to ensure normal production. The moving block 3 and the connecting block 21 engage the bearing 42. When it is necessary to disassemble or install the rotating roller 4, the moving block 3 is moved downward. After the moving block 3 moves away from the connecting block 21, the rotating roller 4, rotating shaft 41, and bearing 42 can be removed from the connecting block 21. Disassembly and assembly are convenient and quick.

[0018] Two movable blocks 3 are fixedly connected to one side of an mounting plate 5. A scraper 51 is rotatably mounted between the inner walls of the mounting plate 5. The scraper 51 is inclined and normally contacts the outer periphery of the rotating roller 4. When the rotating roller 4 is working, the scraper 51 can scrape off the impurities adhering to the rotating roller 4. The scraped impurities fall onto the mounting plate 5 along the inclined surface of the scraper 51. The impurities are then disposed of uniformly by the staff. When disassembling or assembling the rotating roller 4, the scraper 51 rotates inside the mounting plate 5 and moves away from the rotating roller 4. There is no need to remove or adjust the scraper 51, which simplifies the disassembly and assembly process.

[0019] Example 2: Please see Figure 1-5 This is the second embodiment of the present invention. Based on the previous embodiment, the movable block 3 is rotatably provided with rotating rods 31 on both sides. A snap-fit ​​plate 33 is fixedly connected to the middle of the outer periphery of the rotating rod 31. Two sliding grooves 34 are opened on the side of the connecting block 21 near the movable block 3. A snap-fit ​​groove 32 is opened at the top of the sliding groove 34. The snap-fit ​​plate 33 snaps into the snap-fit ​​groove 32. When the rotating rod 31 is rotated, the rotating rod 31 rotates and drives the snap-fit ​​plate 33 to rotate in the snap-fit ​​groove 32. When the snap-fit ​​plate 33 rotates to the position of the sliding groove 34, the rotating rod 31 is pulled down, and the rotating rod 31 drives the snap-fit ​​plate 33 to move in the sliding groove 34. When the snap-fit ​​plate 33 is in the snap-fit ​​groove 32, the movable block 3 can be snapped into one side of the connecting block 21.

[0020] The connecting block 21 has cylindrical grooves 35 on both sides of its top. A circular piece 36 is slidably connected inside the cylindrical groove 35. The top of the rotating rod 31 passes through the connecting block 21 and is fixedly connected to the bottom surface of the circular piece 36. A spring 37 is fixedly connected to the bottom surface of the circular piece 36. The bottom end of the spring 37 is fixedly connected to the bottom surface of the cylindrical groove 35. The spring 37 is movably sleeved on the outer circumference of the rotating rod 31. When the rotating rod 31 moves, it drives the circular piece 36 to move in the cylindrical groove 35. The cooperation between the circular piece 36 and the cylindrical groove 35 compresses the spring 37. The moving block 3 moves downward and opens. After the rotating rod 31 is released, the spring 37 uses its elasticity to restore the circular piece 36 to its original position. The circular piece 36 drives the rotating rod 31 to return to its original position. The rotating rod 31 drives the moving block 3 to return to its initial position, which facilitates the subsequent engagement of the bearing 42.

[0021] A cylindrical rod 52 is rotatably connected to the middle of the mounting plate 5. The outer periphery of the cylindrical rod 52 is fixedly connected to the bottom of the scraper 51. The rotation of the cylindrical rod 52 drives the scraper 51 to rotate. When the device is removed, the scraper 51 moves away from the rotating roller 4. When the device is installed, the scraper 51 contacts the rotating roller 4, which facilitates the subsequent cleaning of impurities.

[0022] Two racks 54 are fixedly connected to one side of the connecting block 21, and gears 53 are fixedly connected to both ends of the cylindrical rod 52. The gears 53 mesh with the corresponding racks 54. The movement of the cylindrical rod 52 drives the gears 53 to move on the racks 54. The cooperation between the racks 54 and the gears 53 drives the cylindrical rod 52 to rotate.

[0023] A servo electric cylinder 22 is fixedly connected to the top surface of the gantry frame 11. The piston rod end of the servo electric cylinder 22 passes through the gantry frame 11 and is fixedly connected to the top surface of the moving plate 2. When the servo electric cylinder 22 is opened, the servo electric cylinder 22 drives the moving plate 2 to move through the piston rod.

[0024] When this utility model is in use, the servo electric cylinder 22 is opened. The servo electric cylinder 22 drives the moving plate 2 to move through the piston rod. The movement of the moving plate 2 drives the connecting block 21 and the moving block 3 to move. The movement of the moving block 3 drives the rotating roller 4, the rotating shaft 41, and the bearing 42 to move. The rotating roller 4 comes into contact with the material. During production, the operator can adjust the pressure of the rotating roller 4 according to the actual situation to ensure normal production. In the production state, the scraper 51 contacts the outer periphery of the rotating roller 4. The rotation of the rotating roller 4 drives the rotating shaft 41 to rotate on the bearing 42. When the rotating roller 4 rotates, the scraper 51 continuously scrapes the material. Impurities are scraped off, and the scraped impurities move along the inclined surface to the top surface of the mounting plate 5. The workers then collect and process the impurities on the mounting plate 5. When the rotating roller 4 needs to be disassembled and replaced, the rotating rod 31 is rotated. The rotation of the rotating rod 31 causes the locking plate 33 to rotate within the locking groove 32. When the locking plate 33 rotates to the position of the sliding groove 34, the rotating rod 31 is pulled down, causing the locking plate 33 to move within the sliding groove 34. Simultaneously, the movement of the rotating rod 31 causes the circular piece 36 to move within the cylindrical groove 35. The engagement of the circular piece 36 with the cylindrical groove 35 compresses the spring 37. As the moving block 3 moves... Simultaneously, the moving block 3 drives the mounting plate 5 to move synchronously. The movement of the mounting plate 5 drives the cylindrical rod 52 and gear 53 to move. The gear 53 moves on the rack 54, which drives the gear 53 to rotate. The gear 53 drives the cylindrical rod 52 to rotate, and the cylindrical rod 52 drives the scraper 51 to rotate away from the rotating roller 4, thereby preventing the scraper 51 from moving away from the rotating roller 4 and ensuring the normal movement of the rotating roller 4. When the moving block 3 moves away from the connecting block 21, the rotating roller 4, rotating shaft 41, and bearing 42 can be removed from the connecting block 21, making disassembly and assembly convenient and quick. In this utility model, the moving block 3, connecting... The cooperation between block 21 and the component secures the bearing 42. When the roller 4 needs to be disassembled or replaced, simply rotate the rotating rod 31 and pull down the moving block 3. Then the roller 4, rotating shaft 41, and bearing 42 can be removed from the connecting block 21. Disassembly and assembly are convenient and quick. At the same time as the moving block 3 is pulled down, the scraper 51 automatically moves away from the roller 4, eliminating the need for additional removal or adjustment of the scraper 51. This simplifies the disassembly and assembly process and improves maintenance efficiency. In this utility model, the mounting plate 5 can scrape off impurities on the roller 4 during the production process, avoiding uneven force caused by impurities sticking together and ensuring production quality.
