[0001] The utility model relates to the technical field of waterproof construction, in particular to a two-component coating weighing system. Background Art

[0002] In the waterproof construction process, spraying polyurethane waterproof coating is one of the waterproof construction processes. Polyurethane waterproof coating is a two-component reaction-curing synthetic polymer waterproof coating with good elasticity and extensibility. In order for the polyurethane waterproof coating to have better performance, such as improving the drying time, the ratio of the two components of the coating needs to be adjusted. The commonly used adjustment method on the market is to change the volume of the sprayed coating by adjusting the volume of the coating spraying cylinder, thereby achieving the purpose of ratio adjustment. However, the two-component coating is mixed by weight ratio, which results in the need to determine the spray quantity by calculation during use. The calculation process is cumbersome and prone to errors, resulting in deviations in the mixing ratio and affecting the mixing effect. Therefore, there is an urgent need for a device that can weigh the two-component coating, accurately measure the consumption of the coating, and directly obtain the ratio result of the two-component coating.

DETAILED DESCRIPTION

[0025] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 and Figure 2As shown, a two-component paint weighing system is characterized in that it includes a vehicle body 1, a base 2, a material barrel 3, a weighing module and a control module. The base 2 is provided with two, and the two bases 2 are both arranged on the vehicle body 1. The material barrel 3 is installed on the base 2. The material barrel 3 is provided with two, which are used to hold two components of paint. The two material barrels 3 are respectively placed on the two bases 2. The weighing module is arranged between the vehicle body 1 and the base 2. The weighing module is provided with two groups, and the two groups of weighing modules weigh the paint in the two material barrels 3 respectively; the control module is arranged on the vehicle body 1 and is electrically connected to the weighing module. The control module is a single-chip microcomputer. A control box is also provided on the vehicle body 1. The control module is located in the control box. A display screen is provided on the control box, and the display screen is electrically connected to the control module. In the present invention, two-component paints are respectively contained in two material barrels 3, and are extracted from the two material barrels 3 during the spraying process. Since the usage ratio of the two-component paints is different, the paint consumption in the two material barrels 3 is also different. The weighing module can weigh the paint in the two material barrels 3 and transmit the weighing information to the control module. The weighing module can detect the paint consumption in the two material barrels 3 per unit time, and the usage ratio of the two groups of paints in the spraying process can be directly obtained, and it is directly transmitted to the control module and displayed. The operator can intuitively obtain the consumption ratio of the two paints, which is simple, fast and accurate. When the consumption ratio is abnormal, it can also be quickly discovered and modified to return the paint ratio to normal; and a threshold value can be set in the control module. When the weighing module detects that the paint in the material barrel 3 is lower than the set threshold, it will promptly remind the operator to add paint to avoid mixing ratio errors due to lack of paint, which affects the waterproof construction.

[0029] In another embodiment, a guard plate 4 is provided on the base 2, and the guard plate 4 is located on the outside of the barrel 3. The guard plate 4 can limit the barrel 3 to prevent the barrel 3 from falling due to vibration or inertia during the spraying process.

[0030] like Figure 3 As shown, in another embodiment, the weighing module includes an upper bracket 5, a lower bracket 6 and a weighing sensor 7, the upper bracket 5 is fixedly connected to the base 2 by bolts, the lower bracket 6 is fixedly connected to the vehicle body 1 by bolts, the weighing sensor 7 is located between the upper bracket 5 and the lower bracket 6, the weighing sensor is electrically connected to the control module, the lower end face of the weighing sensor 7 is fixedly connected to the lower bracket 6 by bolts, the upper end face of the weighing sensor 7 is fixedly connected to the upper bracket 5 by bolts, and when the barrel 3 is filled with paint, the weighing sensor 7 can detect weight changes and transmit the detected weight to the control module.

[0031] In another embodiment, the weighing module can also be directly connected to the material barrel 3, that is, the upper bracket 5 is fixedly connected to the bottom of the material barrel 3 by bolts, the lower bracket 6 is fixedly connected to the vehicle body 1 by bolts, and the weighing sensor 7 is located between the upper bracket 5 and the lower bracket 6. The upper and lower end faces of the weighing sensor 7 are respectively fixedly connected to the upper bracket 5 and the lower bracket 6 by bolts. The weighing sensor 7 can weigh the material barrel 3 and the paint in the material barrel 3. Since the weight of the material barrel 3 remains unchanged, the weight change detected by the weighing sensor 7 is the weight change of the paint in the material barrel 3.

[0032] like Figure 4 As shown, in another embodiment, a heating module is provided in the barrel 3, and the heating module is located at the bottom of the barrel 3. The heating module includes a heating plate 8, and the heating plate 8 is electrically connected to the control module, and is used to heat the paint in the barrel 3. It can reduce the viscosity of the paint in the barrel 3, enhance the fluidity of the paint, facilitate the extraction of the paint by the spraying component, and is beneficial to the accuracy of the proportion, while also facilitating spraying.

[0033] In another embodiment, the heating module also includes a temperature sensor, which is integrated on the heating plate and electrically connected to the control module. The temperature sensor can detect the temperature of the paint in the barrel 3 and transmit the temperature information to the control module. When the detected temperature is lower than the set threshold, the control module controls the heating plate 8 to heat the paint to increase the paint temperature and improve the temperature and fluidity of the paint; when the temperature sensor detects a temperature higher than the threshold, the control module controls the heating plate 8 to stop heating to avoid degradation of the paint performance due to excessively high temperature.

[0034] In another embodiment, a support plate 9 is fixedly provided at the bottom of the barrel 3, and the support plate 9 is tilted. The heating plate 8 is fixedly provided on the support plate 9, and the support plate 9 is tilted to facilitate the flow of the paint. After being heated by the heating plate 8, the paint can flow downward along the support plate 9 until it reaches the lowest point in the barrel 3, and finally be extracted from the barrel 3 for spraying operation, which can reduce the paint residue in the barrel 3, reduce waste and improve the accuracy of the ratio of the two-component paint.

[0035] In another embodiment, an alarm module is also included. The alarm module is an audible and visual alarm. The alarm module is electrically connected to the control module. When the weighing module transmits the weighing information to the control module, and the control module detects that the paint consumption ratio in the two barrels 3 per unit time is different from the set ratio, the control module controls the alarm module to sound an alarm, and promptly reminds the operator to stop spraying and modify the data in time.

[0036] In another embodiment, the inner wall of the barrel 3 is provided with an anti-sticking layer, and the anti-sticking layer is also arranged on the heating plate 8 and the support plate 9. The anti-sticking layer is a polytetrafluoroethylene coating, which plays an anti-sticking role and prevents the paint from adhering to the inner wall of the barrel 3 and solidifying after a long time, causing clogging of the spray gun.

[0037] In another embodiment, a spraying assembly is also provided on the vehicle body 1, and the spraying assembly includes two groups of plunger pumps 10 and a driving member 11 for driving the plunger pumps 10 to move. The two groups of plunger pumps 10 are fixedly arranged on a mounting plate, and the mounting plate is fixedly connected to the vehicle body 1. The driving member 11 is arranged on a fixed plate, and the piston rod of the plunger pump 10 is fixedly connected to a sliding plate. The driving member 11 is a hydraulic cylinder, and the piston rod of the hydraulic cylinder is fixedly connected to the sliding plate. The two groups of plunger pumps 10 are respectively connected to two barrels 3 through pipelines. The driving member 11 drives the sliding plate to slide up and down during the extension and retraction process, thereby driving the piston rod of the plunger pump 10 to slide up and down, sucking paint from the barrel 3 and spraying it from the plunger pump 10, thereby achieving a spraying effect, and the piston rod length of one group of plunger pumps 10 is adjustable, so that the piston rod strokes of the two groups of plunger pumps 10 are different, so that the absorbed paint is different, thereby achieving the effect of adjusting the proportion of the two groups of paints.
