Description

Technical Field

[0001] The utility model relates to the technical field of acrylic plate detection, in particular to a temperature resistance detection device used for acrylic plate processing. Background Art

[0002] Acrylic is an important plastic polymer material that was developed earlier. It has good transparency, chemical stability and weather resistance, is easy to dye and process, and has a beautiful appearance. It is widely used in the construction industry.

[0003] When acrylic sheets are produced, their properties vary depending on the degree of polymerization of their raw materials, the production process, and the impurity content. In particular, their hardness and melting points vary significantly. Therefore, during the production and processing of acrylic sheets, their hardness and temperature resistance need to be tested. When testing the temperature resistance of acrylic sheets, the high temperature of the hot spot will be conducted to the surrounding area. Therefore, when testing acrylic sheets of different volumes, and heating different areas during the test, the final results of the test will be affected, resulting in inaccurate melting point detection of the acrylic sheets. For this reason, a new type of testing equipment is needed to test the temperature resistance of acrylic sheets. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a temperature resistance testing device for acrylic plate processing, which can utilize the characteristic that the hardness of the acrylic plate changes after reaching the melting point to detect the temperature resistance of the acrylic plate, thereby avoiding the problem of inaccurate detection caused by different volumes of acrylic plates and different heating areas.

[0005] The technical solution for achieving the purpose of the utility model is: a temperature resistance detection device for acrylic plate processing, comprising a support, on which a detection component is arranged, the detection component comprises a telescopic motor, a pressure plate, an extrusion column, a sliding sleeve, a heat insulation board and a heating plate, the telescopic motor is fixedly connected to the support, the pressure plate is fixedly connected to the output shaft of the telescopic motor, the extrusion column is fixedly connected to the pressure plate, the sliding sleeve is slidably connected to the extrusion column, the heat insulation board is fixedly connected to the sliding sleeve, and the heating plate is fixedly connected to the heat insulation board.

[0006] Preferably, the detection assembly also includes a spring and a pressure sensor, the pressure sensor is fixedly connected to the insulation board, the pressure sensor is located inside the sliding sleeve, one end of the spring is fixedly connected to the extrusion column, and the other end of the spring is fixedly connected to the pressure sensor.

[0007] Preferably, the detection component also includes a display screen, two display screens are fixedly connected to the heat insulation board, and the two display screens are electrically connected to the pressure sensor and the heating plate respectively.

[0008] Preferably, hinges are provided at both ends of the support, and baffles are hingedly connected to the two hinges.

[0009] Preferably, the two baffles are fixedly connected with a first magnet, and the support is fixedly connected with two second magnets.

[0010] Compared with the prior art, the utility model has the following significant advantages:

[0011] In the utility model, starting the telescopic motor can make the heating plate press against the acrylic plate. When the heating plate presses against the acrylic plate, the output shaft of the telescopic motor continues to move downward for a short distance. At this time, the heating plate can no longer move downward, and the pressure plate moves downward, then the spring will be compressed for a distance, and the spring in the compressed state will apply pressure to the pressure sensor. One of the display screens is used to display the indication of the pressure sensor. When the telescopic motor is turned off, the pressure indication on the display screen remains stationary. At this time, the heating plate is started to heat the acrylic plate. When the temperature of the acrylic plate rises to its melting point, the acrylic plate begins to soften. At this time, the elastic force of the spring makes the heating plate tend to press downward, thereby causing the acrylic plate to deform. When the acrylic plate is deformed under the extrusion of the heating plate, the compression degree of the spring will change. At this time, the pressure from the spring applied to the pressure sensor will also change, so the pressure indication displayed on the display screen will change. Therefore, when it is observed that the pressure indication on the display screen begins to change, it means that the temperature of the heating plate has reached the melting point of the acrylic plate, thereby completing the temperature resistance test of the acrylic plate.

[0018] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides a temperature resistance detection device for acrylic plate processing through improvement. The technical solution of the utility model is:

[0020] like Figure 1-Figure 3 As shown, a temperature resistance testing device for acrylic plate processing includes a support 1, on which a testing component 2 is arranged, the testing component 2 includes a telescopic motor 21, a pressing plate 22, an extrusion column 23, a sleeve 24, a heat insulation board 25 and a heating plate 26, the telescopic motor 21 is fixedly connected to the support 1, the pressing plate 22 is fixedly connected to the output shaft of the telescopic motor 21, the extrusion column 23 is fixedly connected to the pressing plate 22, the sleeve 24 is slidably connected to the extrusion column 23, the heat insulation board 25 is fixedly connected to the sleeve 24, and the heating plate 26 is fixedly connected to the heat insulation board 25. The heating plate 26 can be electrically heated and is used to resist the acrylic plate and heat the acrylic plate by contacting with the acrylic plate. The heat insulation board 25 adopts a material with good heat insulation to prevent the temperature of the heating plate 26 from being transmitted to the heat insulation board 25.

[0021] Furthermore, the detection component 2 also includes a spring 27 and a pressure sensor 28. The pressure sensor 28 is fixedly connected to the insulation board 25. The pressure sensor 28 is located inside the sliding sleeve 24. One end of the spring 27 is fixedly connected to the extrusion column 23, and the other end of the spring 27 is fixedly connected to the pressure sensor 28. When the heating plate 26 presses against the acrylic plate, the pressure plate 22 continues to move downward for a distance, and the spring 27 will be in a compressed state. At this time, the pressure sensor 28 can generate an indication. When the acrylic plate reaches the melting point, it will soften. At this time, the heating plate 26 will cause the acrylic plate to deform and move downward, thereby relaxing the spring 27, and the pressure on the pressure sensor 28 will also change at this time.

[0022] Furthermore, the detection component 2 also includes a display screen 29. Two display screens 29 are fixedly connected to the insulation board 25. The two display screens 29 are electrically connected to the pressure sensor 28 and the heating plate 26 respectively. The two display screens 29 can respectively display the pressure exerted on the pressure sensor 28 and the temperature of the heating plate 26.

[0023] Furthermore, hinges 3 are provided at both ends of the support 1, and baffles 4 are hinged on the two hinges 3. When the two baffles 4 are lifted upward, the entire device can be sealed, so that the device is easy to store.

[0024] Furthermore, the two baffles 4 are fixedly connected with a first magnet 5, and the support 1 is fixedly connected with two second magnets 6. When the two baffles 4 are lifted, the two first magnets 5 will be adsorbed together with the two second magnets 6 respectively, so that the two baffles 4 are fixed.

[0025] The specific working method is: first open the two baffles, place the acrylic plate to be tested inside the support 1, start the telescopic motor 21, press its output shaft downward, drive the pressure plate 22 to move downward, and the downward movement of the pressure plate 22 will cause the extrusion column 23 to move downward. Under the action of the spring 27, the sliding sleeve 24, the pressure sensor 28, the heat insulation plate 25 and the heating plate 26 will all move downward, so that the heating plate 26 is against the acrylic plate. When the heating plate 26 is against the acrylic plate, the output shaft of the telescopic motor 21 continues to move downward for a short distance. At this time, the heating plate 26 can no longer move downward, and the pressure plate 22 moves downward, then the spring 27 will be compressed for a distance, and the spring 27 in the compressed state will apply pressure to the pressure sensor 28. One of the display screens 29 is used to display the reading of the pressure sensor 28. Turn off the telescopic motor 21, and the pressure reading on the display screen 29 remains stationary. At this time, start the heating plate 26 to slowly increase the temperature of the heating plate 26. The display screen 29 is used to display the temperature change of the heating plate 26. When the heating plate 26 is tightly pressed against the acrylic plate, the acrylic plate will be in a heated state. Since the thermal conductivity of the acrylic plate is not high, the temperature of the heating plate 26 needs to be increased at an extremely slow rate to ensure that the temperature of the acrylic plate is always the same as the temperature of the heating plate 26. When the temperature of the acrylic plate rises to its melting point, the acrylic plate will begin to soften and tend to melt. At this time, the elastic force of the spring 27 makes the heating plate 26 tend to press downward, thereby causing the acrylic plate to deform. When the acrylic plate is deformed under the extrusion of the heating plate 26, the compression degree of the spring 27 will change. At this time, the pressure from the spring 27 applied to the pressure sensor 28 will also change, so the pressure indication displayed on the display screen 29 will change. Therefore, when it is observed that the pressure indication of the display screen 29 begins to change, it means that the temperature of the heating plate 26 has reached the melting point of the acrylic plate, thereby completing the temperature resistance test of the acrylic plate.

[0026] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
