[0024] The utility model discloses a drying drum temperature monitoring device, comprising:

[0025] The drying cylinder 5 is arranged at the head end of the drying line and is used to dry the fabric to be processed;

[0026] The mounting frame 1 comprises a support rod 11 arranged on one side of the drying cylinder 5, a mounting plate 12 is arranged above the support rod 11, and the mounting plate 12 is located higher than the drying cylinder 5;

[0027] The probe 2 is arranged on the bottom surface of the mounting plate 12, and the probe 2 is aligned with the end of the drying cylinder 5 that is not covered by the cloth. The probe 2 is used to detect the surface temperature of the drying cylinder 5;

[0028] The wiping component 3 includes a power unit 32 arranged on the top surface of the mounting plate 12. The output end of the power unit 32 passes through the mounting plate 12 and is provided with a transmission component 31. The end of the transmission component 31 away from the power unit 32 is provided with a wiping plate 33. The wiping plate 33 is arranged on one side of the probe 2, and the wiping surface of the wiping plate 33 abuts against the lens of the probe 2. The power unit 32 drives the wiping plate 33 to rotate through the transmission component 31 so that the wiping plate 33 cleans the condensed water vapor on the probe 2.

[0029] In a specific implementation, when the drying drum 5 dries the cloth, the probe 2 measures the temperature of the part of the drying drum 5 that is not covered by the cloth, thereby monitoring the surface temperature of the drying drum 5. Steam is generated around the drying drum 5 when the cloth is dried. The steam near the probe 2 condenses to generate water vapor on the probe 2. At this time, the power unit 32 drives the wiping plate 33 to rotate through the transmission component 31, so that the wiping plate 33 contacts the probe 2 during the rotation and wipes off the water vapor accumulated on the probe 2.

[0030] The utility model monitors the temperature of the surface of the drying cylinder 5 arranged at the head end of the drying line through the probe 2, and the wiping component 3 cleans the water vapor on the probe 2, thereby reducing the factors that interfere with the probe 2 when monitoring the temperature. Compared with the temperature measurement method in the return water pipe, this solution can monitor the steam inlet temperature without affecting the operation of the return water pipe, thereby improving the monitoring accuracy and reducing the detection error.

[0031] Preferably, the probe 2 can be a thermal infrared monitoring probe in the prior art.

[0032] Preferably, the power unit 32 can adopt a motor in the prior art.

[0033] It should be noted that the wiping plate 33 can be made of transparent materials that can transmit infrared rays, such as quartz and infrared-grade optical glass, and the wiping surface of the wiping plate 33 can be made of transparent flexible materials such as polyethylene and polypropylene.

[0034] In one embodiment, the transmission component 31 includes a first transmission rod 311 vertically rotatably arranged below the mounting plate 12, the output end of the power unit 32 is connected to the first transmission rod 311, the power unit 32 is used to drive the first transmission rod 311 to rotate around the axis of the first transmission rod 311, and a second transmission rod 312 is vertically slidably arranged at one end of the first transmission rod 311 away from the power unit 32, and one end of the second transmission rod 312 is inserted into the first transmission rod 311 and rotates together with the first transmission rod 311. The wiping plate 33 is arranged at one end of the second transmission rod 312 away from the first transmission rod 311. When the probe 2 needs to be wiped, the power unit 32 drives the second transmission rod 312 to rotate through the first transmission rod 311, so that the wiping plate 33 rotates with the axis of the first transmission rod 311 as the center and wipes off the water vapor on the probe 2 during the rotation. The wiping component 3 also includes a guide member 34 arranged around the transmission member 31, and the guide member 34 is used to drive the second transmission rod 312 to move back and forth up and down when the second transmission rod 312 rotates.

[0035] With such a design, when there is water vapor on the probe 2, the power unit 32 drives the second transmission rod 312 to rotate through the rotation of the first transmission rod 311. The wiping plate 33 contacts the probe 2 and wipes off the water vapor when the second transmission rod 312 rotates. When the wiping plate 33 wipes off the water vapor on the probe 2, the wiping plate 33 will temporarily affect the temperature value monitored by the probe 2. During the rotation of the second transmission rod 312, the guide member 34 drives the second transmission rod 312 to move up and down. After wiping off the water vapor, the wiping plate 33 descends with the second transmission rod 312 and approaches the drying cylinder 5. The drying cylinder 5 heats the wiping plate 33 through heat transfer, so that the temperature of the wiping plate 33 is close to the surface temperature of the drying cylinder 5. When the wiping plate 33 wipes off the water vapor again, the monitoring fluctuation when the wiping plate 33 wipes the probe 2 is reduced.

[0036] In one embodiment, the guide member 34 includes a sleeve 341 surrounding the first transmission rod 311, the sleeve 341 is fixedly connected to the first transmission rod 311, and a guide groove 342 is provided on the inner wall of the end of the sleeve 341 away from the mounting plate 12. The guide groove 342 is arranged in an annular shape and surrounds the second transmission rod 312. The guide groove 342 is formed by sequentially splicing a first flat section 3421, a second flat section 3422 and two arc-shaped inclined sections 3423. The height of the first flat section 3421 is higher than that of the second flat section 3422. 22, and the first flat section 3421 is arranged on the side of the inner wall of the sleeve 341 close to the probe 2, the second flat section 3422 is arranged on the side of the inner wall of the sleeve 341 away from the probe 2, and the second transmission rod 312 is provided with a first connecting rod 35, and the end of the first connecting rod 35 away from the second transmission rod 312 is slidably arranged in the guide groove 342. When the second transmission rod 312 rotates, the first connecting rod 35 rotates with the second transmission rod 312 and moves along the track of the guide groove 342, so that the second transmission rod 312 can move vertically back and forth when rotating.

[0037] With this design, when the wiping plate 33 rotates with the second transmission rod 312 and wipes the probe 2, the first connecting rod 35 slides in the first flat section 3421 at this time. When the wiping plate 33 completes wiping, the first connecting rod 35 rotates with the second transmission rod 312 and enters into the inclined section 3423 at one end. At this time, the second transmission rod 312 drives the wiping plate 33 to rotate and move downward until the first connecting rod 35 enters the second flat section 3422. At this time, the wiping plate 33 is close to the drying cylinder 5. When the first connecting rod 35 slides in the second flat section 3422, the drying cylinder 5 heats the wiping plate 33 until the first connecting rod 35 enters into the inclined section 3423 at the other end. At this time, the second transmission rod 312 drives the wiping plate 33 to rotate and move upward and enter into the first flat section 3421 again, and the wiping plate 33 wipes the probe 2 again.

[0038] In one embodiment, a cleaning component 4 is provided on the bottom surface of the mounting plate 12, and the cleaning component 4 includes a second connecting rod 41 vertically arranged on the side of the sleeve 341 away from the probe 2, and a cleaning block 42 is provided at the bottom end of the second connecting rod 41. When the first connecting rod 35 moves into the second flat section 3422, the wiping surface of the wiping plate 33 contacts the cleaning block 42.

[0039] With such a design, when the wiping plate 33 wipes the probe 2 and slides in the guide groove 342 through the first connecting rod 35 and rotates with the second transmission rod 312 and descends to the second flat section 3422, the wiping surface of the wiping plate 33 contacts the bottom surface of the cleaning block 42. As the second transmission rod 312 continues to rotate, the cleaning block 42 wipes off the water vapor on the wiping plate 33 to prevent water vapor from remaining on the wiping plate 33 and being carried onto the probe 2.

[0040] It should be noted that the cleaning block 42 can be made of elastic and water-absorbent materials such as cotton and sponge.

[0041] In one embodiment, the support rod 11 is a telescopic rod, and the mounting plate 12 is arranged at the protruding end of the telescopic rod. The telescopic setting of the support rod 11 can adjust the probe 2 to a suitable height according to the actual installation height of the drying drum 5, and can also adjust the relative distance between the probe 2 and the drying drum 5 separately according to actual needs.

[0042] Preferably, the support rod 11 can be an electric telescopic rod in the prior art.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, "multiple", "multiple groups", and "several" refer to more than two.
