Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PMI foam size measurement, in particular to a resin plate foaming size measurement device for a high-temperature drying room. Background Art
[0002] Resin board is a kind of artificial stone board. PMI foam is a rigid closed-cell foam material with the characteristics of light weight, high strength, environmental protection, high temperature resistance, low dielectric, easy processing, fatigue resistance, easy bonding, and high closed-cell rate.
[0003] In order to obtain PMI foam with appropriate density, the foaming size of the resin board is usually controlled by the relevant foaming ratio. However, it is inconvenient to measure the resin board in the drying room. It can only be measured by manually opening the drying room and using measuring tools such as tape measures. The repeated opening and closing of the drying room will cause serious heat loss of the resin board, making it difficult to continue foaming, prolonging the foaming time, increasing energy consumption, and reducing production efficiency. In addition, the temperature near the door in the drying room is much lower than the area far from the door, causing uneven heating of the resin board and uneven local density of the foam. Secondly, the temperature inside the drying room is as high as more than 200 degrees Celsius. Manual operation is accompanied by certain risks and can easily cause burns.
[0004] Based on this, a device for measuring the foaming size of a resin plate for a high-temperature drying room is now provided, which can eliminate the disadvantages of the existing device. Utility Model Content

[0031] In one embodiment, Figure 2 and Figure 3 As shown, the measuring component includes a slider 10, which is slidably connected in the slide groove 4, and a beam-type infrared photoelectric sensor 11 is fixedly connected to the top of the slider 10. A moving component for moving the slider 10 is provided inside the support bar 3. The beam-type infrared photoelectric sensor 11 is installed on both sides of the drying room 1, and the horizontal height is controlled to be consistent with the height of the foamed resin board. When the size of the resin board begins to grow during the foaming process, the sensor signal blocked in the horizontal direction increases and is fed back to the control system to obtain the real-time size effect of the resin board.
[0032] In one embodiment, Figure 3 , Figure 4 and Figure 5As shown, the moving component includes a limiting groove 12, and the limiting groove 12 is opened on one side of the support bar 3. The slider 10 is fixedly connected with an internal threaded rod 13 on one side, and the internal threaded rod 13 is slidably connected in the limiting groove 12. The internal threaded rod 13 is threadedly connected with a first nut 14, and one side of the first nut 14 is movably abutted against the support bar 3. By rotating the first nut 14, it is moved away from the internal threaded rod 13, and then a thrust is applied to the opposing infrared photoelectric sensor 11 to make the internal threaded rod 13 slide in the limiting groove 12, driving the slider 10 to slide in the slide groove 4, and then the first nut 14 is rotated again to make it movably abut against the support bar 3, thereby increasing the friction force and achieving the limiting effect.

A threaded hole 16 is provided on the top of the support block 7, and a second nut 17 is threadedly connected to the threaded hole 16. By rotating the second nut 17 to keep it away from the threaded hole 16, the friction force on the rotating column 15 is reduced, and then an external force is applied to the support bar 3 to enable it to rotate, so that the opposing infrared photoelectric sensor 11 can be on the same horizontal plane as the resin plate. After the adjustment is completed, the second nut 17 is rotated again to pass through the threaded hole 16, thereby increasing the friction force on the rotating column 15 and limiting the support bar 3.
[0034] Example 2
[0035] In one embodiment, Figure 3 As shown, the opposing infrared photoelectric sensor 11 on one side is a transmitter, and the opposing infrared photoelectric sensor 11 on the other side is a receiver, and the opposing infrared photoelectric sensors 11 are on the same horizontal line, so that the opposing infrared photoelectric sensors 11 on both sides cooperate with each other to complete the measurement.

[0037] In one embodiment, Figure 3 As shown, a wedge block is provided below the connection between the support block 7 and the support bar 3 , and the wedge block can increase the supporting force of the support block 7 .
[0038] The working principle of the utility model is as follows: the above embodiment discloses a device for measuring the foaming size of a resin board for a high-temperature drying room, wherein a resin board is placed in a drying room 1, and then the height of the foaming is adjusted according to the required height, and the motor 5 is started to drive the first threaded rod 6 to rotate, and the first threaded rod 6 drives the support block 7 to move, and the support block 7 can only move horizontally up and down because the limit rod 8 limits the support block 7, and the support block 7 drives the support bar 3 to move at the same time, and the support bar 3 drives the opposing infrared photoelectric sensor 11 to move, and when the appropriate height is reached, according to the resin board The inclination can be adjusted by rotating the second nut 17 to keep it away from the threaded hole 16, thereby reducing the friction on the rotating column 15. Then, external force is applied to the support bar 3 to enable it to rotate, so that the reflected infrared photoelectric sensor 11 can be on the same horizontal plane as the resin board. After the adjustment is completed, the second nut 17 is rotated again to pass through the threaded hole 16, thereby increasing the friction on the rotating column 15 and limiting the support bar 3. Finally, the pre-foaming size is input into the control system. When the size of the resin board begins to grow during the foaming process, the sensor signal blocked in the horizontal direction increases and is fed back to the control system to obtain the real-time size of the resin board. When the resin board reaches the pre-foaming size, the control system alarms and feeds back to the operator to end the foaming. At the same time, if the resin board foams abnormally and a large amount of arching and bending occurs in the vertical direction, the blocked signal will be restored and monitored by the control system. This device can also move the opposing infrared photoelectric sensor 11 according to resin boards of different sizes, wherein the first nut 14 is rotated to move it away from the internal threaded rod 13, and then a thrust is applied to the opposing infrared photoelectric sensor 11 to make the internal threaded rod 13 slide in the limit groove 12, driving the slider 10 to slide in the slide groove 4, and then the first nut 14 is rotated again to make it move against the support bar 3 to increase the friction force and achieve the limiting effect.
