Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model discloses an adhesion tester for quality inspection, including a bottom box 1. At the upper side positions near the left and right inner walls of the bottom box 1, lifting mechanisms 2 are provided, and locking mechanisms 3 are fixedly installed on the left and right lifting mechanisms 2. A pressing frame 4 is fixedly installed between the locking mechanisms 3. At the position near the right side of the upper side wall of the bottom box 1, a return air pipe 5 is provided. The return air pipe 5 is connected to a temperature regulating mechanism 7 through an extraction assembly 6. The temperature regulating mechanism 7 is installed on the lower inner wall of the bottom box 1. The air outlet of the temperature regulating mechanism 7 is connected to a cloth air pipe 9 through an air outlet pipe 8. The cloth air pipe 9 is installed on the upper side wall of the bottom box 1. At the position near the rear edge of the upper surface of the bottom box 1, a mounting frame 10 is fixedly installed. On the upper surface of the mounting frame 10, a first electric telescopic rod 11 is fixedly installed. On the lower surface of the piston of the first electric telescopic rod 11, a mounting plate 12 is fixedly installed. At the positions corresponding to the lower surface of the mounting plate 12 and the pressing frame 4, tension sensors 13 are installed. On the lower surfaces of the tension sensors 13, pressing plates 14 are installed, and the length and width of the pressing plates 14 match the length and width of the inner wall of the pressing frame 4. On the upper surface of the mounting plate 12, a heat preservation cover 16 is installed through a guiding mechanism 15. A rubber sealing ring is provided on the lower surface of the heat preservation cover 16 to ensure a tight fit with the upper surface of the bottom box 1.

[0022] Specifically, the lifting mechanism 2 includes a second electric telescopic rod 201 and a column 202. The second electric telescopic rod 201 is fixedly installed on the inner wall of the bottom box 1. On the upper surface of the piston rod of the second electric telescopic rod 201, a column 202 is installed, and the column 202 is movably inserted into the upper side of the upper side wall of the bottom box 1.

[0023] In this implementation scheme, the piston rod of the second electric telescopic rod 201 drives the column 202 to move up and down, so that the column 202 drives the pressing frame 4 to move up and down through the locking mechanism 3, and the pressing frame 4 can press and fix the plaster.

[0024] Specifically, the locking mechanism 3 includes a rectangular sleeve 301 and a locking bolt 302. The rectangular sleeve 301 is locked and fixed on the column 202 through the locking bolt 302, and the rectangular sleeve 301 is fixedly connected to the side surface of the pressing frame 4.

[0025] In this implementation scheme, the locking bolt 302 enables the rectangular sleeve 301 to be disassembled and assembled, which is convenient for the later disassembly and cleaning of the pressing frame 4.

[0026] Specifically, the temperature adjustment mechanism 7 includes a first three-way solenoid valve assembly 701, an electric heating box 702, a semiconductor refrigeration box 703, a second three-way solenoid valve assembly 704, a controller 705, and a temperature sensor 706. The first three-way solenoid valve assembly 701 is communicated with the air outlet of the extraction assembly 6. The air outlet of the first three-way solenoid valve assembly 701 is respectively communicated with the electric heating box 702 and the semiconductor refrigeration box 703. The communicated air outlets of the electric heating box 702 and the semiconductor refrigeration box 703 are communicated with the air outlet pipe 8 through the second three-way solenoid valve assembly 704. The controller 705 and the temperature sensor 706 are installed on the inner wall of the upper side of the bottom box 1, and the temperature sensor 706 is communicated with the upper side of the upper side wall of the bottom box 1.

[0027] In this implementation scheme, according to the detection requirements, the temperature sensor 706 monitors the temperature of the plaster test area covered by the heat preservation cover 16. When low-temperature testing is required, the first three-way solenoid valve assembly 701 and the second three-way solenoid valve assembly 704 are respectively communicated with the semiconductor refrigeration box 703. The extraction assembly 6 evacuates the inside of the heat preservation cover 16 through the return air pipe 5, so that the cold air flows into the air distribution pipe 9 through the air outlet pipe 8, and then is blown into the heat preservation cover 16 through the air distribution pipe 9, so that the cold air enters the heat preservation cover 16 to cool the plaster to be tested inside the heat preservation cover 16. On the contrary, when high-temperature testing is required, the first three-way solenoid valve assembly 701 and the second three-way solenoid valve assembly 704 are respectively communicated with the electric heating box 702. The extraction assembly 6 evacuates the inside of the heat preservation cover 16 through the return air pipe 5, so that the hot air flows into the air distribution pipe 9 through the air outlet pipe 8, and then is blown into the heat preservation cover 16 through the air distribution pipe 9, so that the hot air enters the heat preservation cover 16 to heat the plaster to be tested inside the heat preservation cover 16. The temperature inside the heat preservation cover 16 is detected by the temperature sensor 706, and the controller 705 is used to adjust the temperature.

[0028] Specifically, the guiding mechanism 15 includes a guiding rod 151 and a guiding hole 152. The guiding rods 151 are fixedly installed at the four corners of the upper surface of the mounting plate 12 in a rectangular shape. Guiding holes 152 are opened on the upper side walls of the heat preservation cover 16 corresponding to the piston rods of the guiding rod 151 and the first electric telescopic rod 11. The guiding rod 151 is movably inserted into the guiding hole 152.

[0029] In this implementation scheme, the heat preservation cover 16 moves up and down along the guiding rod 151 through the guiding hole 152. When testing, the heat preservation cover 16 can cover the upper surface of the bottom box 1. When not testing, the heat preservation cover 16 rises with the mounting plate 12.

[0030] Specifically, an operation panel 17 is installed on the front side of the bottom box 1, and a display screen 18 is arranged on the operation panel 17.

[0031] In this embodiment, the operation panel 17 facilitates the control of each function, and the display screen 18 displays the values of the tensile sensor 13 and the temperature sensor 706.

[0032] During use, place the plaster to be tested on the lower surface of the pressing frame 4, with the plaster of the plaster facing upward and leaking through the hollow area of the pressing frame 4. Then, drive the column 202 to move downward by the second electric telescopic rod 201. The column 202 drives the pressing frame 4 to move downward through the locking mechanism 3. The pressing frame 4 presses the plaster tightly on the upper surface of the bottom box 1. Then, drive the mounting plate 12 to move downward by the first electric telescopic rod 11. The mounting plate 12 drives the pressing plate 14 to move downward through the tensile sensor 13, so that the pressing plate 14 presses tightly on the plaster surface of the plaster. At this time, the heat preservation cover 16 moves downward through the guiding mechanism 15, so that the heat preservation cover 16 covers the upper surface of the bottom box 1. The temperature sensor 706 in the temperature regulating mechanism 7 detects the temperature inside the heat preservation cover 16, and the controller 705 adjusts the temperature. According to the detection requirements, the temperature sensor 706 monitors the temperature of the plaster test area covered by the heat preservation cover 16. When low-temperature testing is required, the first three-way solenoid valve assembly 701 and the second three-way solenoid valve assembly 704 are respectively connected to the semiconductor refrigeration box 703. The extraction assembly 6 evacuates the inside of the heat preservation cover 16 through the return air pipe 5, so that the cold air flows into the air distribution pipe 9 through the air outlet pipe 8, and then is blown into the heat preservation cover 16 through the air distribution pipe 9, so that the cold air enters the heat preservation cover 16 to cool the plaster to be tested inside the heat preservation cover 16. On the contrary, when high-temperature testing is required, the first three-way solenoid valve assembly 701 and the second three-way solenoid valve assembly 704 are respectively connected to the electric heating box 702. The extraction assembly 6 evacuates the inside of the heat preservation cover 16 through the return air pipe 5, so that the hot air flows into the air distribution pipe 9 through the air outlet pipe 8, and then is blown into the heat preservation cover 16 through the air distribution pipe 9, so that the hot air enters the heat preservation cover 16 to heat the plaster to be tested inside the heat preservation cover 16. After reaching the set temperature, wait for 10 - 15 minutes, and then drive the piston rod of the first electric telescopic rod 11 to drive the tensile sensor 13 to move upward through the mounting plate 12. The tensile sensor 13 drives the pressing plate 14 to move upward. When testing that the pressing plate 14 adheres to the plaster of the plaster, the tensile sensor 13 will be pulled downward, and the pulling force is displayed through the display screen 18, achieving the effect of testing the adhesion of the plaster.

[0033] In summary, this adhesion tester for quality inspection uses mechanical automatic testing, making the test results more accurate. And during the testing process, it can change the test temperature, and can obtain the adhesion values under low-temperature, normal-temperature, and high-temperature environments, making the test range wider and the test results more accurate.
