[0021] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0022] like Figure 1 , Figure 2 As shown, a speed-regulating belt scale with a cleaning structure includes:
[0023] Mounting bracket 1;
[0024] Belt scale device 2; Belt scale device 2 is mounted on mounting bracket 1;
[0025] Scraper 3;
[0026] The first adjusting component is used to adjust the pressure between the scraper 3 and the belt 6 of the belt scale device 2. The adjusting end of the adjusting component acts on the scraper 3, and the adjusting component is installed on the mounting bracket.
[0027] The first adjusting component includes:
[0028] Support frame 4; Support frame 4 is mounted on mounting frame 1, and scraper 3 is fixedly mounted on support frame 4;
[0029] Adjusting cylinder 5; Adjusting cylinder 5 and scraper 3 are respectively pressed into contact with both sides of belt 6, scraper 3 is located on the outer side of belt 6, and adjusting cylinder 5 is installed on support frame 4.
[0030] The adjusting cylinder 5 is rotatably mounted on the support frame 4.
[0031] The first adjusting member also includes at least one first elastic member 7, the two elastic ends of the first elastic member 7 acting on the mounting frame 1 and the support frame 4 respectively.
[0032] The first elastic element 7 is a first compression spring. The two ends of the first compression spring are fixedly connected to the mounting bracket 1 and the support bracket 4, respectively. The first compression spring is located inside the belt 6 and is always in a compressed state.
[0033] When belt 6 becomes loose, stretched, or thermally expanded due to prolonged operation, its overall length increases. At the location of scraper 3, belt 6 is prone to snagging on scraper 3, hindering its cleaning. In this situation, the force between belt 6 and adjusting cylinder 5 decreases, and the elastic force of the first elastic element 7 on support frame 4 exceeds the force between belt 6 and adjusting cylinder 5. Support frame 4 moves downward under the action of the first elastic element 7, simultaneously moving belt 6, scraper 3, and adjusting cylinder 5 downward together until the elastic force of the first elastic element 7 and the compressive force between belt 6 and adjusting cylinder 5 reach equilibrium. This prevents belt 6 from snagging on scraper 3, facilitating cleaning. Since scraper 3 and adjusting cylinder 5 are fixedly mounted on support frame 4, the distance between belt 6 and scraper 3 at scraper 3 is fixed, effectively solving the problem of excessive or insufficient pressure between scraper 3 and belt 6. Simultaneously, adjusting cylinder 5 also tensions belt 6.
[0034] When the temperature drops and cold contraction occurs, the force between the belt 6 and the adjusting cylinder 5 increases. The elastic force of the first elastic element 7 on the support frame 4 is less than the force between the belt 6 and the adjusting cylinder 5. The support frame 4 moves upward under the force between the belt 6 and the adjusting cylinder 5, and at the same time, it drives the belt 6, the scraper 3 and the adjusting cylinder 5 located at the scraper 3 to move upward together, so as to avoid the situation where the pressure between the scraper 3 and the belt 6 is too small.
[0035] The speed-regulating belt scale also includes a second adjusting component, which is used to adjust the distance between the driving roller 10 and the driven roller 11 of the belt scale device 2. The adjusting end of the second adjusting component acts on the driven roller 11, and the discharge port of the belt scale device 2 is located at one end of the belt 6 on the driving roller 10.
[0036] The second adjusting component includes a connecting frame 8 and at least one second elastic element 9. The driven roller 11 is rotatably mounted on the connecting frame 8. The two ends of the second elastic element 9 act on the connecting frame 8 and the mounting frame 1, respectively. The second elastic element 9 is always in an energy storage state. The direction of the elastic force generated by the second elastic element 9 on the connecting frame 8 is the direction from the driving roller 10 to the driven roller 11.
[0037] The second elastic element 9 is a second compression spring. The two ends of the second compression spring are fixed to the connecting frame 8 and the mounting frame 1, respectively. The second compression spring is always in a compressed state.
[0038] When belt 6 becomes loose, stretched, or thermally expanded due to prolonged operation, its overall length increases, potentially causing it to detach from the drive roller 10 and driven roller 11. This prevents the belt scale device 2 from achieving its intended purpose. In this situation, the force between belt 6 and driven roller 11 decreases, and the elastic force of the second elastic element 9 on driven roller 11 exceeds the compressive force between belt 6 and driven roller 11. Under the action of the second elastic element 9, driven roller 11 moves away from drive roller 10, increasing the distance between drive roller 10 and driven roller 11 and increasing the force between belt 6 and driven roller 11 until the elastic force of the second elastic element 9 and the compressive force between belt 6 and driven roller 11 reach equilibrium, thus achieving the purpose of tensioning belt 6.
[0039] When the temperature drops and contraction occurs, the force between the belt 6 and the driven roller 11 increases. The elastic force of the second elastic element 9 on the driven roller 11 is less than the force between the belt 6 and the driven roller 11. Under the force between the belt 6 and the driven roller 11, the driven roller 11 moves towards the direction closer to the driving roller 10, reducing the distance between the driving roller 10 and the driven roller 11, and reducing the force between the belt 6 and the driven roller 11, until the elastic force of the second elastic element 9 and the squeezing force between the belt 6 and the driven roller 11 reach a balance, thus preventing the belt 6 from becoming too tight.
[0040] The technical solution of this utility model is not limited to the specific embodiments described above. All technical modifications made based on the technical solution of this utility model shall fall within the protection scope of this utility model.
