Description

Technical Field

[0001] The invention belongs to the technical field of coating detection, and in particular relates to a coating fluidity detection device. Background Art

[0002] Silicone coatings usually refer to coatings made with silicone resins made by copolymerization of dichlorosilane and trichlorosilane as the base material. They have excellent oxidation resistance, UV resistance and light retention. The outdoor durability of well-formulated silicone coatings is better than that of acrylic-MF, polyester-MF or urethane coatings, and is close to that of highly fluorinated polymer coatings. Silicone resins are also used as base materials for resistant coatings, such as aluminum-colored silicone resin chimney paints that can be used for years at temperatures above 500°C. The fluidity of silicone coatings has a great influence on the effect of their use, so it is necessary to test the fluidity of silicone coatings.

The clamping motor can drive the first gear to rotate, thereby driving the second gear and the third gear to rotate. The third gear can drive the bidirectional screw to rotate. The two bidirectional screws rotate in the same direction. Under the joint action, the extrusion plate can be driven to move along the axial direction of the bidirectional screw. The threads at both ends of the bidirectional screw are opposite. Therefore, when the bidirectional screw rotates, the two extrusion plates can be driven to approach or move away from each other. When the two extrusion plates are close to each other, they can press against the corresponding first rotating shaft and second rotating shaft to fix the first rotating shaft and the second rotating shaft, so that the weight detection component and the funnel remain in a vertical state.

[0019] Furthermore, a handle is provided on the top of the funnel, and the handle is connected to the weight detection component. The provided handle facilitates the movement of the funnel and can also increase the space between the funnel and the weight detection component, making it easier to pour paint into the funnel.

[0020] Furthermore, the handle is connected to the weight detection assembly by no less than two bolts, which facilitates the disassembly and fixation between the funnel and the weight detection assembly, and when fixed, the consistency of multiple fixed positions can be maintained. After the funnel is removed from the weight detection assembly, it is easy to clean.

[0021] Furthermore, a receiving tray is provided on the base for receiving the paint flowing out of the funnel.

When the controller controls the unloading motor to start and the paint starts to be unloaded, the timer is controlled to start timing at the same time. As the paint is unloaded, the paint in the funnel gradually decreases. When the weight detection component detects that the weight of the paint flowing out of the funnel reaches a set value, the controller controls the timer to stop timing, so that the time required for a certain amount of paint to flow out of the funnel can be accurately obtained, thereby improving the accuracy of fluidity detection;

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-3 As shown, this embodiment provides a coating fluidity detection device, comprising:

[0035] A frame 1, wherein the frame 1 is provided for mounting a funnel 2;

[0036] A weight detection assembly 8, which is suspended on the frame 1;

[0037] A funnel 2 is arranged at the weighing end of a weight detection component 8 and is used for weighing through the weight detection component 8; a discharge portion 3 is protruded from the bottom of the funnel 2, and a discharge channel 4 communicating with the funnel 2 is vertically provided in the discharge portion 3; the discharge channel 4 is extended to have an accommodating cavity, a plug 5 for blocking the discharge channel 4 is provided in the accommodating cavity, the plug 5 is sealingly and rotatably connected to the accommodating cavity, a connecting hole 6 is provided on the plug 5, and the connecting hole 6 is used to connect the discharge channel 4 blocked by the plug 5, and the A feeding motor 7 is provided on one side of the feeding part 3, and the output shaft of the feeding motor 7 passes through the feeding part 3 and is connected to the cock 5; the funnel 2 is provided for loading the paint, and the feeding channel 4 opened through the feeding part 3 is used for the paint to flow out of the funnel 2, and the feeding motor 7 is provided to cooperate with the cock 5 located in the feeding channel 4 to control the opening and closing of the feeding channel 4, and the paint is discharged when the feeding channel 4 is opened; the fluidity of the paint is detected by adding paint into the funnel 2 and recording the time required for a certain amount of paint to flow out;

[0038] A timer 9 is arranged on the frame 1;

[0039] The controller is electrically connected to the unloading motor 7, the weight detection component 8, and the timer 9. The controller is used to control the operation of the unloading motor 7 and synchronously obtain the data of the weight detection component 8 and the timer 9 in real time.

[0040] The present invention can detect the weight of the paint in the funnel 2 by setting a weight detection component 8 between the frame 1 and the funnel 2, so as to accurately control the amount of paint added to the funnel 2 during each detection, improve the consistency of each fluidity detection, and thus improve the accuracy of fluidity detection.

[0041] The present invention also controls the unloading of the paint by setting a unloading motor 7, and then electrically connects the controller with the timer 9, the unloading motor 7 and the weight detection component 8. When the controller controls the unloading motor 7 to start and the paint starts to be unloaded, it also controls the timer 9 to start timing. As the paint is unloaded, the paint in the funnel 2 gradually decreases. When the weight detection component 8 detects that the weight of the paint flowing out of the funnel 2 reaches the set value, the controller controls the timer 9 to stop timing, so as to accurately obtain the time required for a certain amount of paint to flow out of the funnel 2, thereby improving the accuracy of fluidity detection.

[0042] When the device is in use, if the desktop used to place the device is uneven, the weight detection component 8 and the funnel 2 will be tilted. If the device is changed, the tilt angles of the weight detection component 8 and the funnel 2 will change. The tilt of the weight detection component 8 will affect the accuracy of the weight detection. The fluidity detection needs to be based on the judgment of the time for a certain amount of paint to flow out of the funnel 2. The accuracy of the weight detection will further affect the accuracy of the fluidity detection. The different tilt angles of the funnel 2 will directly lead to the speed at which the paint flows out of the funnel 2, directly affecting the detection of the paint fluidity. To solve this problem, a mounting block 10 is provided on the top of the frame 1. The bottom of the mounting block 10 is rotatably connected to a first connecting block 12 through a first rotating shaft 11. The first connecting block 12 The bottom of the connecting block 12 is rotatably connected to a second connecting block 14 via a second rotating shaft 13, and the weight detection component 8 is installed at the bottom of the second connecting block 14; the second rotating shaft 13 is arranged in a horizontal direction, and the first rotating shaft 11 is perpendicular to the second rotating shaft 13. The first connecting block 12 and the second connecting block 14 are rotatably connected between the weight detection component 8 and the top of the frame 1, so that the first rotating shaft 11 and the second rotating shaft 13 of the first connecting block 12 and the second connecting block 14 are rotatably connected and are perpendicular to each other, and the second rotating shaft 13 is arranged horizontally, which can enable the weight detection component 8 and the funnel 2 connected to the second connecting block 14 to remain vertical under the action of gravity, thereby improving the detection accuracy of the weight detection component 8 and the fluidity detection accuracy.

[0043] When the device is in use, it will automatically balance according to gravity, and the unloading motor 7 is arranged on one side of the unloading part 3, making it difficult for the funnel 2 to remain vertical after automatic balancing. To solve this problem, a counterweight block 15 is provided on the side of the unloading part 3 away from the unloading motor 7, which is used to balance the weight of the unloading motor 7 so that the funnel 2 can remain vertical under the action of gravity.

[0044] The device controls the opening and closing of the feeding channel 4 through the feeding motor 7. Since the plug 5 is in sealed rotation connection with the accommodating chamber, the friction between the plug 5 and the accommodating chamber may cause the funnel 2 to shake when the plug 5 rotates, thereby affecting the speed of the paint flowing out and causing the weight detection component 8 to detect unstable values. To solve this problem, the first rotating shaft 11 is fixed to the first connecting block 12, the second rotating shaft 13 is fixed to the second connecting block 14, and the mounting block 10 and the first connecting block 12 are both provided with Figure 4The clamping assembly 16 shown in the figure, the two groups of the clamping assemblies 16 are respectively used to clamp the two ends of the first rotating shaft 11 and the second rotating shaft 13; the clamping assembly 16 includes a clamping motor 161, a first gear 162, two second gears 163, two third gears 164, two bidirectional screw rods 165 and two extrusion plates 166, the first gear 162 is coaxially mounted on the output shaft of the clamping motor 161, the first gear 162 is respectively meshed with the two second gears 163, the two second gears 163 are respectively meshed with the two third gears 164, the two third gears 164 are respectively coaxially mounted on the middle of the two bidirectional screw rods 165, the adjacent ends of the two bidirectional screw rods 165 are respectively threadedly connected to the two ends of the same extrusion plate 166, the first rotating shaft 11 and the The second rotating shaft 13 is located between the two corresponding extrusion plates 166. The clamping motor 161 is arranged to drive the first gear 162 to rotate, thereby driving the second gear 163 and the third gear 164 to rotate. The third gear 164 can drive the bidirectional screw rod 165 to rotate. The two bidirectional screw rods 165 have the same rotation direction. Under the joint action, the extrusion plate 166 can be driven to move axially along the bidirectional screw rod 165. The threads at both ends of the bidirectional screw rod 165 are opposite. Therefore, when the bidirectional screw rod 165 rotates, the two extrusion plates 166 can be driven to approach or move away from each other. When the two extrusion plates 166 approach each other, they can press against the corresponding first rotating shaft 11 and the second rotating shaft 13 to fix the first rotating shaft 11 and the second rotating shaft 13, so that the weight detection component 8 and the funnel 2 remain in a vertical state.
