As a key testing device, the material adhesion tester plays an important role in the field of materials science and engineering. By quantitatively testing and analyzing the adhesion properties of materials, the material adhesion tester provides reliable data support for material selection, process optimization and product quality control. Therefore, with the continuous improvement of material performance requirements, the research and development and application of adhesion testers are also receiving increasing attention and attention.

[0003] In the current industrial production and scientific research fields, the demand for testing the adhesion and cleanability of materials is increasing. These tests are of great significance for ensuring product quality, optimizing production processes, and improving material utilization efficiency. Especially when dealing with complex attachments such as wine lees and oil stains, accurate and efficient testing methods are needed to evaluate their adhesion and cleanability.

[0004] At present, there are many methods for characterizing the adhesion properties of materials, and there is no unified adhesion test method and device. There are only devices for studying certain properties, such as contact angle testers, adhesion testers, etc., which cannot measure the surface adhesion of materials in an all-round way. Moreover, using each set of equipment to test certain properties separately is a lot of work and the operation is also cumbersome. Summary of the invention

[0005] The object of the present invention is to provide a device and method for testing the adhesion properties and cleanability of materials in order to solve the above-mentioned problems, thereby improving the problem that the existing testing devices are unable to conduct a comprehensive test on the adhesion of the material surface and the testing method is also relatively cumbersome to operate.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A device and method for testing the adhesion performance and cleanability of materials, the device comprising a support base and a test machine shell, the support base comprising a support column and a support plate, the support column is arranged below the support plate, the support column is used to support the device, the test machine shell is arranged on the support base, and the support base is also provided with: a support frame, on which a material coating device is arranged, the material coating device is arranged above a sample loading device, the material coating device is used to coat the material on the sample, and the sample loading device is used to load the sample; the material coating device comprises a material coating cylinder, a primary hydraulic rod and a secondary hydraulic rod, the primary hydraulic rod and the secondary hydraulic rod drive the material coating cylinder Move in the vertical direction; a cleaning device is connected to the support frame, and the cleaning device cleans the sample loading device and the material coating device; a wind drying device includes a blower motor and blades, the blower motor outlet is connected to a fan blade, the blower motor drives the fan blade to generate wind, one end of the fan blade is connected to the ventilation duct, and the ventilation duct delivers the wind to a specified position; the other end of the ventilation duct is connected to the blade, and the wind direction is controlled by adjusting the rotation angle of the blade; a machine vision analysis device includes an image collector and a collector rail, the collector rail is connected to the support frame, the image collector is connected to the collector rail through a third slider, and the third slider drives the image collector to slide on the collector rail.

[0008] Furthermore, the material coating device is arranged on the support frame, the primary hydraulic rod is connected to the support frame, the secondary hydraulic rod is connected to the top of the material coating cylinder, and the secondary hydraulic rod pushes the material in the material coating cylinder to move.

[0009] Due to the above arrangement, the height of the material coating device can be adjusted by controlling the lifting and lowering of the hydraulic rod, thereby adjusting the thickness and area of ​​the material coating, so that the material is evenly coated on the sample with a certain area, thickness and pressure.

[0010] Furthermore, the sample loading device includes a bearing bracket and a loading platform, the loading platform is connected to the bearing bracket through a bearing; a pressure plate is provided on the loading platform, one end of the pressure plate is connected to the loading platform through a bolt, and there is a gap between the other end of the pressure plate and the loading platform; a servo motor is connected to one end of the bearing, and the servo motor drives the rotating shaft in the bearing to rotate.

[0011] Due to the above arrangement, the pressure plate can exert a certain pressure on the material, so that the gap between the material and the sample changes; at the same time, the bearing drives the loading platform to rotate, so that the loading platform can be tilted at different angles, allowing the material to separate from the sample under the action of gravity, thereby testing the viscosity of the material.

[0012] It should be noted that a rotating shaft is provided in the bearing, and the loading platform is driven to rotate by the rotating shaft.

[0013] Furthermore, the cleaning device includes a water tank, a flushing head and a cleaning guide rail: the water tank is arranged on a supporting base, a cleaning guide rail is arranged on the water tank, a flushing head is arranged on the cleaning guide rail, the flushing head is sleeved on the cleaning guide rail through a first slider, and the flushing head is driven by the first slider to move on the cleaning guide rail; one end of the cleaning guide rail is slidably connected to the bracket rail through a second slider, and the cleaning guide rail is driven by the second slider to slide on the bracket rail; a water pump is provided on the water tank, the water pump is connected to the flushing head, the water pump transports the cleaning liquid to the flushing head, and the water pump is controlled by a pumping motor to transport water.

[0014] Due to the above arrangement, the flushing head can be moved from the cleaning device to the bracket through the connection between the cleaning rail and the bracket rail, so that the sample can be flushed at different angles, thereby calculating the mass of the material dropped under the loading platform and calculating the adhesion rate and cleaning rate.

[0015] Furthermore, a cover plate is provided on the water tank, and the cover plate is divided into two parts, a movable part and a fixed part, and the two parts are hinged by pins; by rotating the movable part with the connection as the axis, cleaning liquid can be added to the water tank.

[0016] Due to the above arrangement, the water tank is convenient to open and close, and the opening and closing direction of the water tank is opposite to the direction of the flushing head, so it will not affect the movement of the flushing head.

[0017] Furthermore, a weight detection device is provided on the support base, and the weight detection device is arranged below the sample loading device, and the weight detection device is used to measure the mass of the material.

[0018] Due to the above arrangement, the weight detection device is arranged below the sample loading device, and the material dropped from the sample can fall into the weight detection device, which weighs the dropped material and liquid and provides data for solving the viscosity rate and cleaning rate.

[0019] Further, a method for testing the adhesion performance of a material and the cleanability of a material comprises the following steps:

[0020] S100: Place the sample to be tested, open the glass door of the testing machine housing, place the sample to be tested on the loading table of the sample loading device, and press the sample to be tested with a pressing plate;

[0021] S200: Applying materials, starting the hydraulic device, causing the primary hydraulic rod to move first, driving the material coating device to approach the sample loading device, and when the material coating device contacts the sample, the primary hydraulic rod stops moving; the hydraulic device then drives the secondary hydraulic rod to push the material coating cylinder, causing the material in the material coating cylinder to contact the sample surface, completing the coating operation, and the material coating device is reset;

[0022] S300: Rotate the loading platform by a servo motor to drive the loading platform to rotate, so that the material is separated from the sample surface under the action of gravity, and the weight detection device records the weight of the dropped material;

[0023] S400: flushing the sample, starting the cleaning device, setting the flow rate, pressure and flow rate of the water flow and the cleaning time through the pumping motor; aligning the flushing head with the loading platform to flush the sample, after reaching the set flushing time, the pumping motor stops working, the flushing is completed, and the loading platform returns to the initial position;

[0024] S500: Air-dry the sample. The wind direction of the air outlet is controlled by the blades. By changing the air outlet angle of the air outlet, the air outlet direction is aligned with the sample, and the material on the sample is air-dried. The air-drying time can be set.

[0025] S600: Record data. The image collector moves to the bracket rail through the collector rail. When the image collector moves above the sample, it collects the area, thickness and volume information of the material, and transmits the information to the computer processor for data processing, so as to calculate the adhesion rate and cleaning rate of the material.

[0026] It should be noted that when air-drying the sample, the angle of the air outlet blade can be changed manually or automatically.

[0027] Due to the above method, the image collector moves to the bracket rail through the collector rail, collects data from the loading platform on the support frame, and collects different data by moving to different positions. The data is transmitted to the processor for data processing, and then the adhesion rate and cleaning rate of the material are accurately calculated.

[0028] Furthermore, in step S200, when the secondary hydraulic rod pushes the material coating cylinder, after the material contacts the surface of the sample, different forces are applied to the secondary hydraulic rod to adjust the thickness and area of ​​the dressing on the sample.

[0029] Furthermore, in step S200 and step S400, the weight detection device detects and records the weight of the sample before and after applying the material, and the weight detection device also detects and records the weight of the sample after rinsing the sample; the weight detection device then transmits the recorded data to a computer processor, and the computer calculates the viscosity and cleaning rate of the material.

[0030] By adopting the above method, it is possible to record the mass of the dropped material and the mass of the liquid, thereby further confirming the viscosity of the material.

[0031] Furthermore, the image collector is used to collect sample information after the wind drying device stops working. When the image collector is needed, the image collector is moved along the bracket rail to above the sample. When the image collector is not needed, the image collector is moved to the collector rail through the bracket rail.

[0032] Due to the adoption of the above method, the image collector collects data on the material on the loading platform sample, and the image collector moves along the bracket guide rail, which can detect all-round data of the sample, including material thickness, area and other data, so that the viscosity calculated later is more accurate.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0034] 1. The flushing head is set on the cleaning guide rail, and the cleaning guide rail is set on the bracket guide rail, and the cleaning guide rail and the bracket guide rail are set at a certain angle, so the flushing head can move in two directions of the cleaning guide rail and the bracket guide rail, which can solve the problem that the existing device needs an external cleaning device and the cleaning device has a limited range of action. The device of the present invention can cover a wider range, so that the cleaning of the sample on the loading platform is more comprehensive.

[0035] 2. The sample coated with the material is rotated, pressurized and cleaned through the test device, and the data is checked through the weight detection device and the visual analysis device to measure the adhesion rate and cleaning rate of the material before and after cleaning. The weight detection device starts measuring when the device starts running, and can monitor the mass of the object in the weight detection device in real time, and then conduct a comprehensive test of the adhesion and cleaning performance of the material.

[0036] 3. By adjusting the material coating pressure, area and thickness applied to the sample by the test device, as well as adjusting the flow rate, pressure and time of flushing the sample, the adhesion and cleaning performance of the sample under a variety of different conditions can be tested. The test conditions can be adjusted and controlled by a computer, which can simplify the test operation steps to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to test the viscosity of the material, the loading platform 303 carrying the sample is rotated so that the material falls from the sample under the action of gravity. The material falls into the weight detection device 7, and the mass of the falling material can be measured. The mass of the material remaining on the sample is calculated based on the mass of the coating material, and then the viscosity of the material is calculated.

[0054] like Figure 3 As shown, the material coating device 4 is arranged above the sample loading device 3, and the material coating device 4 is connected to the hydraulic transmission device 9, and the computer processor 10 controls the hydraulic transmission device 9 so that the material coating device 4 controls the movement of the material loading cylinder 404; the specific connection method is: the primary hydraulic rod 402 is connected to the support frame 101, the hydraulic transmission device 9 is connected to the primary hydraulic rod 402 and the secondary hydraulic rod 403, the primary hydraulic rod 402 drives the material coating device 4 to move in the vertical direction as a whole, the secondary hydraulic rod 403 is connected to the material loading cylinder 404, and the secondary hydraulic rod 403 drives the material loading cylinder 404 to move in the vertical direction, including material coating and material compaction.

[0055] like Figure 4As shown, the cleaning device 5 includes a water tank 501, a flushing head 502 and a cleaning guide rail 503; a cover plate is provided on the water tank 501, and the cover plate is divided into two parts, namely, a movable part and a fixed part, and the two parts are hinged by a pin; by rotating the movable part with the connection as an axis, cleaning liquid can be added to the water tank. A water pump 507 is provided on the water tank 501, one end of the bracket guide rail 506 is connected to the water pump 507, and the other end is connected to the support frame 101, and a second slider 505 is sleeved on the bracket guide rail 506, and the second slider 505 is connected to the cleaning guide rail 503, and the flushing head 502 is connected to the cleaning guide rail 503 through the first slider 504, and the first slider 504 drives the flushing head 502 to slide on the cleaning guide rail 503, and the second slider 505 drives the cleaning guide rail 503 to slide on the bracket guide rail 506, thereby realizing the full range of movement of the flushing head 502 on the plane. The cleaning device 5 controls the power and working time of the water pump 507 by the computer processor 10 to complete the operation of flushing the material. The flushing head 502 can slide on the cleaning guide rail 503 and the support guide rail 506, thereby ensuring full coverage of the sample loading device 3, making the measured material viscosity data more accurate and reliable.

[0056] like Figure 5 As shown, in the wind drying device 6, the blower motor 602 is connected to the fan blade 601, and the blower motor 602 drives the fan blade 601 to rotate to generate wind. The fan blade 601 is arranged at one end of the ventilation duct 603, and the wind generated by the fan blade 601 is transported to the air outlet through the ventilation duct 603. The air outlet is provided with blades 604. The wind drying device 6 is controlled by the computer processor 10 to directly drive the fan blade 601 to blow air, and then the wind is sent to the air outlet through the ventilation duct 603. The blade 604 of the air outlet is driven by the motor inside thereof and can rotate to control the wind direction, thereby adapting to the different rotation angles of the loading platform 303, so that the samples on the loading platform 303 can be air-dried, thereby improving the air-drying efficiency.

[0057] like Figure 6 As shown, the weight detection device 7 includes a weight detection base 701, a weight detector 702 and a material collection box 703; the material collection box 703 is connected to the sample loading device 3, and the material on the sample loading device 3 falls into the material collection box 703 for weighing. The weighed data information is sent to the computer processor 10 for data analysis.

[0058] like Figure 7As shown, the machine vision analysis device 8 is connected to the bracket rail 506 through a third slider 803 connected to the collector rail 802.

[0059] The computer processor 10 organizes and analyzes the received data, calculates the viscosity and cleanability of the material, and can present it in a visual chart if necessary.

[0060] like Figure 8 As shown, a method for testing the adhesion performance of materials and the cleanability of materials, when measuring the adhesion performance of the sample, first open the glass door 201 of the test machine housing 2, put the sample to be tested on the loading platform 303, pick up one end of the pressing plate 304 and put the sample in, press the sample, and then start the hydraulic transmission device 9.

The flow rate, pressure and flow rate of the water flow are controlled by the pumping motor to the water pump 507. After the set time for flushing is reached, the pumping motor stops working, and the loading platform 303 automatically returns to the horizontal position. Then the wind drying device 6 is started, and the wind direction is controlled by the blade 604 at the air outlet position, so that the material adhered to the sample begins to dry. After drying to a certain extent, the wind drying device 6 stops working, and then the image collector 801 moves to the top of the sample to be tested to analyze the area, thickness, volume, etc. of the residual material. The movement of the image collector 801 does not interfere with the cleaning of the cleaning device 5. After processing by the computer processor 10, the adhesion of the material is measured. The material adhesion rate can be measured by the weight detection device 7 and transmitted to the computer processor 10 for data visualization. By allowing the material to separate from the sample under the action of gravity, the viscosity of the material is measured, and the device further rinses the material to measure the cleaning rate of the material; through the device of this embodiment, the test conditions are continuously adjusted and the data is recorded in real time, so that the test results are more accurate.
