Description

Technical Field

[0001] The utility model relates to the technical field related to liquid crystal glass substrates, in particular to a device for measuring the spiral offset of a liquid crystal substrate glass tank furnace feeder. Background Art

[0002] In substrate glass production, the tank furnace requires continuous feeding, and the feeder is the primary equipment for this process. Its function is to continuously feed the batch material into the tank furnace through the rotation of a screw shaft. The feeder screw is connected to the motor via a chain, which drives the screw shaft to rotate and feed the material. However, the feeder screw can wear and deviate from its coaxiality during operation. This deviation can lead to poor discharge, affecting the shape of the batch mountain inside the tank furnace and, in turn, affecting the stability of the internal process. Regular measurement of the feeder screw deviation is therefore necessary.

[0003] The existing measurement method is to directly use a ruler for measurement. During the measurement process of this method, there is no fixed and clear measuring point, the measurement error is large, and the measured data has low reference value. Therefore, it is of great significance to find a device for measuring the spiral offset of the feeder. Utility Model Content

[0004] The purpose of the utility model is to provide a device for measuring the spiral offset of a liquid crystal substrate glass tank furnace feeder to overcome the problems existing in the prior art. The utility model can effectively, simply and accurately measure the offset of the feeder spiral, reduce measurement errors and enhance the reference value of the measurement data.

[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:

[0006] A device for measuring the spiral offset of a liquid crystal substrate glass tank furnace feeder, characterized in that it includes a fixed sleeve, a through hole is provided in the axial direction of the fixed sleeve, a front cover is provided at the front end of the fixed sleeve, and an offset measuring unit is fixedly mounted on the front cover in a radial direction; the offset measuring unit includes a ruler fixing groove, a ruler is provided in the ruler fixing groove, and a ruler advancing screw is provided at the tail of the ruler;

[0007] Furthermore, the fixing sleeve is cylindrical;

[0008] Furthermore, the outer diameter of the fixed sleeve is the same as the outer diameter of the fire-blocking ring of the feeder, and the fixed sleeve is detachably sleeved on the outer circumference of the fire-blocking ring of the feeder;

[0009] Furthermore, the through hole is at the same center as the spiral of the feeding machine;

[0010] Furthermore, a plurality of handles are installed on the side of the fixing sleeve;

[0011] Furthermore, a handle is installed on each side of the fixing sleeve;

[0012] Furthermore, the number of the offset measurement units is several;

[0013] Furthermore, the number of the offset measurement units is 4;

[0014] Furthermore, the positions of the two adjacent offset measurement units are in a vertical relationship;

[0015] Furthermore, a scale is provided on the ruler.

[0016] The above technical solution has the following advantages or beneficial effects:

[0017] The present utility model provides a device for measuring the screw offset of a liquid crystal substrate glass tank furnace feeder. By arranging an offset measurement unit on a fixed sleeve, accurate measurement of the screw offset is achieved. The ruler serves as a measurement reference and has good straightness and stability, which can ensure the accuracy of the measurement results. The ruler advancing screw tightens the ruler by rotating to fine-tune the position of the ruler, ensuring accurate readings and further improving the accuracy of the measurement. The ruler fixing groove is welded on the fixed sleeve to fix the ruler and ensure that the ruler can move freely in the fixing groove. The design of the present utility model device is simple and clear. The operator only needs to rotate the ruler advancing screw to move the ruler forward and backward, thereby easily completing the offset measurement. This design not only improves work efficiency, but also reduces the difficulty of operation, allowing non-professionals to quickly get started. The present utility model device is also relatively convenient when it needs to be replaced or repaired. During daily maintenance, it is only necessary to simply clean and lubricate the ruler and the advancing screw. In summary, the utility model has significant beneficial effects such as high measurement precision, simple operation and convenient maintenance. It can effectively, simply and accurately measure the offset of the feeder screw, reduce measurement errors and enhance the accuracy of measurement data.

[0018] Furthermore, the outer diameter of the fixed sleeve is the same as the outer diameter of the feeder fire stop ring, ensuring a tight fit between the device and the feeder fire stop ring, reducing vibration and instability factors caused by looseness or excessive gaps, and eliminating measurement errors caused by the instability of the device itself; the through hole is the same as the center of the feeder spiral, so that the offset measurement unit can be accurately positioned on the axis, ensuring that the relative position between the ruler and the spiral remains unchanged during the measurement process, thereby improving the accuracy of the measurement; by accurately measuring the offset of the spiral, the centering state of the spiral can be discovered and adjusted in time to ensure the normal operation of the feeder and the production quality of the product.

[0019] Furthermore, a handle is installed on the side of the fixed sleeve, which makes the installation and removal process of the fixed sleeve on the feeder fire retaining ring easier and faster. The operator can stably move and position the fixed sleeve by holding the handle, avoiding direct contact with high-temperature or complex-structured feeder components, and reducing the possibility of equipment slipping or damage due to improper operation, thereby improving work efficiency, reducing operational risks, and improving work safety.

[0020] Furthermore, the number of offset measuring units is 4. When using the device of the utility model, first rotate the left and right ruler advancing screws to take readings to confirm the left and right offset of the feeder screw, and then rotate the upper and lower ruler advancing screws to take readings to confirm the upper and lower offset of the feeder screw; by rotating the left and right and upper and lower ruler advancing screws, the ruler can be in close contact with the feeder screw, thereby achieving accurate measurement of the offset of the feeder screw in the horizontal and vertical directions; this high-precision measurement method helps to timely discover and correct the position deviation of the feeder screw, ensuring accuracy and stability in the production process.
