Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for installing an infrared probe. Background Art
[0002] Large rollers are a very important type of component in the papermaking industry. According to their functional classification, they include pressing rollers, vacuum rollers, vacuum return rollers, and vacuum suction rollers. Large rollers are driven by motors and perform regular circular motions with the rotating shaft as the center. Roller speed is an important performance parameter in the operation of large rollers, which directly affects the output and quality of paper production. Roller speed mainly refers to the linear speed of the roller, that is, the circumferential linear speed determined by the diameter of the working part of the roller. The linear speed of the roller can be changed to meet different process requirements. In summary, roller speed and its related parameters play a vital role in the calender. Their selection and adjustment directly affect the efficiency of the calendering process, product quality and production costs.
[0003] The roller speed can be measured by infrared measurement, that is, a reference object is installed on the side of the roller, such as a metal block, and then the side of the roller is irradiated with infrared light. When the raised metal block is irradiated, the infrared emission distance changes, which is recorded as one cycle. By timing the time change of one cycle, the running speed of the roller can be calculated.
[0004] The existing large roller speed detection system uses a frame mounted on the side of the large roller, with an infrared probe attached to the frame. This is typically secured to the frame using wire or strapping. The large roller vibrates during operation, which can cause the infrared probe to vibrate significantly, resulting in inaccurate or even no detection. Prolonged vibration can also easily cause the infrared probe to fall. Because the large roller operates in a very tight space, this situation makes it difficult for personnel to adjust the speed, creating the risk of injury and equipment damage. Utility Model Content
[0005] Aiming at the problem in the prior art that the infrared probe is not firmly fixed and is easily deviated or falls off, the utility model provides a fixing device for installing the infrared probe to solve the above problem.
[0006] The technical solution of the utility model is as follows:
[0007] A fixing device for installing an infrared probe comprises: a fixing part and a moving part; the fixing part comprises a sleeve rod; a side wall of the sleeve rod is provided with a through hole, and a fastening bolt is installed in the through hole through a thread; a fixing plate is welded to the side wall of the sleeve rod; a fixing hole is provided on the fixing plate; the moving part comprises a sliding rod; the sleeve rod is sleeved on the outer side of the sliding rod; one end of the sliding rod is provided with a mounting ring for fixing and installing the infrared probe.
[0008] Furthermore, a limit plate is provided on one end of the slide bar relative to the mounting ring, so as to ensure that no matter what angle the fixing device is at, it will not fall out of the sleeve bar forward.
[0009] Furthermore, a pull ring is provided on the limit plate to facilitate the operator to move the slide bar back and forth to adjust the horizontal position of the infrared probe.
[0010] Furthermore, the sleeve rod is slotted in the horizontal direction, and the width of the slot is greater than the width of the connection between the slide rod and the mounting ring, which facilitates the disassembly of the fixed part and the movable part, and also facilitates the replacement of slide rods of different lengths.
[0011] Furthermore, the material of the fixing device is stainless steel.
[0012] Furthermore, an anti-slip pad is provided at the end of the fastening bolt, which can improve the stability of the sliding rod inside the sleeve rod.
