Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a tool for adjusting the tension of a corrector baffle. Background Technology

[0002] The corrector is used in the papermaking industry to adjust the position of the felt or dry wire to prevent deviation. The corrector valve is an important component of the corrector. The tightness of the baffle of the corrector valve must be moderate to avoid damaging the wire edge and springing back to zero. A tool for adjusting the tightness of the corrector baffle is a tool specifically used to adjust the tightness of the corrector baffle in the papermaking industry.

[0003] In existing calibration valves, the position of the valve core is changed by the swinging of a baffle to adjust the compressed air flow. The calibration valve baffle contacts the edge of the dry mesh. If the baffle is too tight, it will cause the edge of the dry mesh to wear out, resulting in a short life of the dry mesh and high maintenance costs. If the baffle is too loose, it will not rebound to the zero position, causing the dry mesh to deviate. In the calibration valve, the baffle and the valve core are connected to the spring base by a spring. Normally, adjusting the spring base inward or outward can adjust the tension of the spring and the baffle. However, the spring base is inside the calibration valve support rod, making it difficult to adjust. Without special tools, two screwdrivers are needed to rotate the spring base to adjust its position. However, adjusting the screwdrivers requires a lot of force and can slip. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for adjusting the tightness of the baffle of a calibrator, so as to solve the problem mentioned in the background art that the current tightness adjustment tools on the market require a lot of force and will slip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tool for adjusting the tightness of a calibrator baffle, comprising a calibrator body, one end of which is provided with a baffle connected to a valve core inside the calibrator body; the other end of which is provided with a support rod, a spring base threadedly connected inside the support rod, a first spring installed at one end of the spring base, the other end of the first spring connected to the valve core inside the calibrator body, an iron block at one end of the spring base, protrusions at both ends of one side of the iron block, limit holes at both ends inside the spring base, and the two protrusions slidingly connected inside the two limit holes respectively, a T-shaped post at the end of the iron block away from the spring base, and a limit component for limiting the iron block inside the spring base.

[0006] Preferably, the limiting component includes two limiting grooves respectively opened at both ends inside the spring base, and each limiting groove is provided with a limiting block. Each of the two limiting blocks is rotatably connected with two limiting rings. One end of each of the four limiting rings is provided with a connecting plate, and a second spring is provided between each of the four connecting plates and the two limiting blocks. Each end of one side of the iron block is provided with a limiting pin.

[0007] Preferably, the length of one end of the T-shaped post is greater than the length of the support rod, and the other end of the T-shaped post is provided with anti-slip patterns.

[0008] Preferably, the iron block is circular, and the diameter of the iron block is the same as the diameter of the spring base.

[0009] Preferably, the two protrusions are equidistant from the center point of the spring base, and the two limiting holes are equidistant from the center point of the iron block.

[0010] Preferably, both protrusions and the two limiting holes are cylindrical, and the diameter of the limiting holes is larger than the diameter of the protrusions.

[0011] Preferably, the two limiting posts are symmetrically arranged around the center of the iron block, and the two limiting blocks are symmetrically arranged around the center of the spring base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] (1) By moving the spring base, the first spring is stretched or compressed, which achieves the effect of adjusting the tightness of the baffle. By adjusting the spring base, the tightness of the baffle can be indirectly changed, which can effectively reduce the direct stress on the baffle and other parts of the corrector, reduce the risk of equipment damage, and avoid the problem of the baffle being too tight or too loose, thereby extending the service life of the dry net or felt.

[0014] (2) By inserting the T-shaped column into the support rod, the protrusion on the iron block is driven to the limit hole. Then, the T-shaped column is rotated to achieve the effect of facilitating the adjustment of the position of the spring base inside the support rod. The design of the T-shaped column provides a larger lever arm, so that the operator only needs to apply a small force to complete the adjustment. It can also avoid slipping or deflection when rotating, and the manufacturing cost is low.

[0015] (3) By setting the limiting component, the iron block on the T-shaped column is limited to the spring base, which avoids the iron block from falling off the spring base due to external force or improper operation. It can also ensure that each adjustment is within the safe range, and avoid the dry net from being worn or running off track due to the iron block falling off or sliding. Attached Figure Description

[0023] 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.

[0024] This utility model provides the following technical solution: a tool for adjusting the tension of a calibrator baffle.

[0025] Example 1: The spring base 4 and the first spring 5 can be used to adjust the tightness of the baffle 2, such as... Figures 1-6As shown, the device includes a calibration valve body 1. One end of the calibration valve body 1 is provided with a baffle 2 that connects to the valve core inside the calibration valve body 1. The other end of the calibration valve body 1 is provided with a support rod 3. A spring base 4 is threadedly connected inside the support rod 3. A first spring 5 is installed at one end of the spring base 4. The other end of the first spring 5 is connected to the valve core inside the calibration valve body 1. One end of the spring base 4 is provided with an iron block 6. Both ends of one side of the iron block 6 are provided with protrusions 7. Limit holes 8 are opened at both ends inside the spring base 4. 7 are slidably connected to the inside of the two limiting holes 8 respectively. The end of the iron block 6 away from the spring base 4 is provided with a T-shaped post 9. The length of one end of the T-shaped post 9 is greater than the length of the support rod 3, and the other end of the T-shaped post 9 is provided with anti-slip pattern. The iron block 6 is circular, and the diameter of the iron block 6 is the same as the diameter of the spring base 4. The two protruding posts 7 are equidistant from the center point of the spring base 4, and the two limiting holes 8 are equidistant from the center point of the iron block 6. The two protruding posts 7 and the two limiting holes 8 are all cylindrical, and the diameter of the limiting hole 8 is greater than the diameter of the protruding post 7.

[0026] In the initial state, the spring base 4 is fixed inside the support rod 3 by a threaded connection, and the first spring 5 is in a preset tension or compression state. The tightness of the baffle 2 is determined by the elastic force of the first spring 5. At this time, the position of the spring base 4 determines the tension or compression of the first spring 5. When it is necessary to adjust the tightness of the baffle 2, the T-shaped post 9 can be inserted into the support rod 3, so that it drives the iron block 6 and the spring base 4 to fit together, and drives the protrusion 7 into the limiting hole 8. Then, hold one end of the T-shaped post 9 and rotate it. Since the spring base 4 is connected inside the support rod 3 by a thread, the rotation will cause it to move along the axis of the support rod 3, thereby changing the tension or compression of the first spring 5, thus adjusting the tightness of the baffle 2. The diameter of the limiting hole 8 is slightly larger than the diameter of the protrusion 7, ensuring that the protrusion 7 can slide smoothly and preventing it from dislodging from the limiting hole 8. The anti-slip pattern of the T-shaped post 9 increases the friction, making it easy to hold and operate.

[0027] Example 2: Unlike Example 1, the limiting component can be used to limit the movement of iron block 6, such as... Figure 6 As shown, the spring base 4 has a limiting component inside to limit the iron block 6. The limiting component includes two limiting grooves respectively opened at both ends inside the spring base 4, and each limiting groove is provided with a limiting block 10. Each limiting block 10 is rotatably connected with two limiting rings 11. One end of each of the four limiting rings 11 is provided with a connecting plate, and a second spring 12 is provided between each of the four connecting plates and the two limiting blocks 10. Each end of one side of the iron block 6 is provided with a limiting pin 13. The two limiting pins 13 are symmetrically arranged with respect to the center of the iron block 6, and the two limiting blocks 10 are symmetrically arranged with respect to the center of the spring base 4.

[0028] When the iron block 6 drives the protruding post 7 into the limiting hole 8, it will also drive the limiting pin 13 to the limiting groove. When the limiting pin 13 approaches the limiting ring 11, the limiting ring 11 is squeezed, which causes the connecting plate to open outward and squeeze the second spring 12. As the iron block 6 continues to move, the limiting pin 13 is completely inserted into the limiting ring 11. The second spring 12 recovers its elasticity, pushes the limiting ring 11 to reset, and locks the limiting pin 13. The symmetrical design of the limiting block 10 and the limiting groove ensures that the limiting pins 13 on both sides of the iron block 6 are fixed by the limiting ring 11 at the same time, ensuring the stability of the position of the iron block 6. When it is necessary to release the limit, the limiting pin 13 can be moved away from the limiting ring 11 by external force.
