Technical Field
[0001] This utility model relates to a metering rod fixing device, and more particularly to a metering rod fixing device, belonging to the field of papermaking machine technology. Background Technology
[0002] A paper machine is a device that converts fibrous pulp, waste paper, or other similar materials into paper. Its working principle and components are relatively complex, but mainly include steps and parts such as paper feeding, pulp distribution, dewatering, pressing, drying, calendering, and winding.
[0003] In a papermaking machine, there is a component called a metering rod, which plays an important metering role. The metering rod rotates during the operation of the equipment, but it will deviate due to the centrifugal force during rotation. When the metering rod becomes eccentric, it will cause measurement errors, thereby affecting the papermaking effect of the papermaking machine.
[0004] Therefore, there is an urgent need for a measuring rod fixing device to solve the above-mentioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a metering rod fixing device for fixing the metering rod of a film transfer sizing machine, preventing the metering rod from shifting during rotation. The device is simple in design, durable, and highly applicable, improving the accuracy of metering and ensuring the papermaking effect of the paper machine.
[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a measuring rod fixing device, comprising a support frame and a fixing mechanism. The fixing mechanism includes a first sleeve sleeved on the measuring rod and a second sleeve rotatably connected to both sides of the first sleeve and fixed on the measuring rod. The first sleeve is fixed by the support frame. The second sleeve includes an upper sleeve and a lower sleeve. Threaded rods are rotatably connected to both sides of the upper sleeve. Threaded holes that are threadedly connected to the threaded rods are opened on both sides of the upper end face of the lower sleeve.
[0007] Preferably, the first sleeve has annular grooves on both sides, and the upper sleeve and the lower sleeve are provided with a semi-circular ring adapted to the annular groove on the side near the annular groove. A number of steel balls are rotatably connected to the inner side of the semi-circular ring.
[0008] Preferably, the first sleeve and the two second sleeves are all copper sleeves, and the surfaces of the first sleeve and the two second sleeves are all provided with an anti-corrosion layer.
[0009] Preferably, grooves are provided on the upper sides of both sides of the upper sleeve, the upper end of the threaded rod is located in the grooves, and the upper end of the threaded rod is provided with an internal hexagonal groove.
[0010] Preferably, the support frame includes a base plate, a vertical support plate disposed on one side of the upper surface of the base plate, and a pressure plate disposed on the upper surface of the vertical support plate, and a welding plate is disposed at the front end of the base plate.
[0011] Preferably, the upper end face of the vertical support plate is provided with a second threaded rod, one end of the pressure plate is sleeved on the second threaded rod, a clamping nut is threadedly connected to the second threaded rod, and a handle is provided on the outside of the clamping nut.
[0012] Preferably, both the pressure plate and the base plate are threadedly connected to a clamping threaded rod, and a second rotating handle is provided at the end of the clamping threaded rod away from the first sleeve.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. The upper and lower sleeves are installed by fitting a semi-circular ring with the annular groove on the first sleeve. The steel ball contacts the surface of the annular groove. The threaded rod on the upper sleeve is screwed into the threaded hole on the lower sleeve for connection and fixation. Finally, the first sleeve is pressed and fixed by the support frame. This ensures that when the measuring rod rotates inside the first sleeve, the second sleeves on both sides rotate with the measuring rod. The fixed first sleeve and the second sleeves on both sides can limit the movement of the measuring rod, effectively preventing the measuring rod from deviating during rotation. The design is simple, durable, and highly applicable, improving the accuracy of measurement and ensuring the papermaking effect of the paper machine.
[0015] 2. By adjusting the position of the pressure plate, move it to the upper end face of the first sleeve. Then, use the handle to rotate the clamping nut to clamp the pressure plate, thereby fixing the pressure plate to the upper end face of the first sleeve and achieving the clamping and fixing of the first sleeve. When the first sleeve is initially clamped and fixed by the pressure plate, rotate the clamping threaded rods at both ends to make them contact the first sleeve until the first sleeve is further clamped and fixed, thereby improving the stability of the first sleeve during fixing.

Detailed Implementation
[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0024] like Figures 1-5 As shown, the measuring rod fixing device provided in this embodiment includes a support frame 1 and a fixing mechanism. The fixing mechanism includes a first sleeve 3 sleeved on the measuring rod 2 and a second sleeve 4 rotatably connected to both sides of the first sleeve 3 and fixed on the measuring rod 2. The first sleeve 3 is fixed by the support frame 1.
[0025] Furthermore, the support frame 1 includes a base plate 12, a vertical support plate 13 disposed on one side of the upper end face of the base plate 12, and a pressure plate 14 disposed on the upper end face of the vertical support plate 13. A welding plate 17 is disposed at the front end of the base plate 12.
[0026] Furthermore, a second threaded rod 15 is provided on the upper end face of the vertical support plate 13, and one end of the pressure plate 14 is sleeved on the second threaded rod 15. A clamping nut 16 is threadedly connected to the second threaded rod 15, and a handle is provided on the outside of the clamping nut 16. When the support frame 1 needs to be installed in a suitable position, the support frame 1 is welded and fixed in a suitable position using the welding plate 17. Then, by adjusting the position of the pressure plate 14, it is moved to the upper end face of the first sleeve 3. Then, the clamping nut 16 is rotated using the handle to clamp the pressure plate 14, thereby fixing the pressure plate 14 to the upper end face of the first sleeve 3, thus achieving the clamping and fixing of the first sleeve 3.
[0027] Furthermore, both the pressure plate 14 and the base plate 12 are threadedly connected with a clamping threaded rod 18. A second rotating handle 19 is provided at the end of the clamping threaded rod 18 away from the first sleeve 3. The second rotating handle 19 facilitates the rotation of the clamping threaded rod 18. When the first sleeve 3 is initially clamped and fixed by the pressure plate 14, the clamping threaded rods 18 at both ends are rotated to make them contact the first sleeve 3 until the first sleeve 3 is further clamped and fixed, thereby improving the stability of the first sleeve 3 when it is fixed.
[0028] The second sleeve 4 includes an upper sleeve 401 and a lower sleeve 402. Both sides of the upper sleeve 401 are rotatably connected with threaded rods 5, and both sides of the upper end face of the lower sleeve 402 are provided with threaded holes 6 that are threadedly connected to the threaded rods 5.
[0029] Furthermore, both sides of the first sleeve 3 are provided with annular grooves 7. The upper sleeve 401 and the lower sleeve 402 are each provided with a semi-circular ring 8 that fits into the annular groove 7 on the side closest to the annular groove 7. Several steel balls 9 are rotatably connected to the inner surface of the semi-circular ring 8. When the measuring rod 2 needs to be limited, the two second sleeves 4 are respectively fixed on both sides of the first sleeve 3. During installation, the upper sleeve 401 and the lower sleeve 402 are first installed using the semi-circular ring 8 fitting into the annular groove 7, ensuring that the steel balls 9 are in contact with the surface of the annular groove 7. After contact, the threaded rod 5 on the upper sleeve 401 and the threaded hole 6 on the lower sleeve 402 are screwed together for connection and fixation. Finally, the first sleeve 3 is pressed and fixed by the support frame 1. This ensures that when the metering rod 2 rotates inside the first sleeve 3, the second sleeves 4 on both sides rotate with the metering rod 2. The fixed first sleeve 3 and the second sleeves 4 on both sides can limit the metering rod 2, effectively preventing the metering rod from deviating during rotation. The design is simple, durable, and highly applicable, improving the accuracy of metering and ensuring the papermaking effect of the paper machine.
[0030] Furthermore, the first sleeve 3 and the two second sleeves 4 are all copper sleeves. Copper sleeves have a high thermal conductivity, which can effectively transfer the heat of mechanical parts and prevent mechanical parts from malfunctioning or being damaged due to excessive temperature. The surface of the first sleeve 3 and the two second sleeves 4 are all provided with an anti-corrosion layer, which can improve the service life of the first sleeve 3 and the two second sleeves 4.
[0031] Furthermore, grooves 10 are provided on the upper sides of both sides of the upper sleeve 401, and the upper end of the threaded rod 5 is located in the groove 10. The upper end of the threaded rod 5 is provided with an internal hexagonal groove 11, which facilitates the rotation of the threaded rod 5 later and can also be hidden in the groove 10.
