[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] In the description of the embodiments of the present invention, it should be understood that terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0036] Polymer facing mortar is made of cement and gelling materials, with the addition of various organic high molecular polymers and inorganic substances. It can be divided into single-component and two-component facing mortars. Scope of application: It can be used for walls in various locations; especially for exterior walls of buildings. The finishing plastering of exterior wall insulation polystyrene boards and extruded boards; Product features: It has high bonding strength; The facing layer and the base layer have sufficient bonding strength, and will not fall off or crack during construction or under long-term self-weight and environmental effects; The facing layer is mostly a thin layer and is applied in layers, and the surface is flat, smooth, delicate and beautiful; It has the advantages of good flexibility, impermeability, waterproofness, crack resistance and easy construction.

[0037] Before polymer mortar leaves the factory, its performance will be tested. One of the tests is the slump test of the product, that is, the water retention, fluidity and cohesion of the product. For the slump test of plastering mortar, a certain amount of plastering mortar will be piled up into a unique shape, and then allowed to stand for a period of time. The slump of the test product will be determined by comparing the height of the collapse and the mass scattered outside. The data after the test will be compared with the existing experimental data. Under the same test conditions, products with excellent values ​​will have excellent performance, and vice versa.

[0038] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, an embodiment of the present invention proposes a slump detection device for polymer plastering mortar, including a detection device 3, wherein the detection device 3 includes a material storage port 31, a first material baffle plate 32, a spring 33, a connecting plate 34, a gravity receiver 35, a cylinder 36, a material limit plate 37, a pull rod 38, a second material baffle plate 39, a material placement plate 310, a material delivery cylinder 311 and an adjustable valve 312.

[0039] In the embodiment of the present invention, a port of a horizontal section is provided at the upper end of the storage port 31, so that when the polymer facing mortar is placed in the storage port 31, the polymer facing mortar can flow out from the port, and a loading plate 310 is provided at the lower part of the storage port 31, and the shape of the loading plate 310 is that the outer side is set higher and the inner side is set lower. When the overflowing polymer facing mortar falls into the loading plate 310, the polymer facing mortar on the outer side will slide to the inner side due to the effect of gravity. A plurality of groups of springs 33 are provided at the lower part of the loading plate 310, and the lower part of each spring 33 is connected to the connecting plate 34. When the loading plate 310 stores the fallen polymer facing mortar, the spring 33 will be compressed, and the lower part of the spring 33 is connected to the connecting plate 34, so the spring 33 will apply the compressed weight to the connecting plate 34. The connecting plate 34 is annular and has a hole inside. The limiting plate 37 passes through the hole inside the connecting plate 34.

[0040] A plurality of gravity receivers 35 are provided at the lower part of the connecting plate 34. The gravity receivers 35 will analyze the gravity received by the connecting plate 34 and transmit the received results to an external device. By detecting the gravity change of the connecting plate 34, the amount of polymer facing mortar placed on the placing plate 310 can be obtained. Generally, if the polymer facing mortar is not easy to collapse, the polymer facing mortar sliding down from the storage port 31 is lighter. On the contrary, if the polymer facing mortar is easy to collapse, more polymer facing mortar is placed on the placing plate 310.

[0041] The mixed polymer facing mortar will be transmitted from the feed port 14 and then enter the storage port 31. During the test, the polymer facing mortar entering the storage port 31 is higher than the highest point of the storage port 31, that is, the polymer facing mortar transmitted from the feed port 14 is larger than the volume of the storage port 31, and the volume of the polymer facing mortar transmitted from the feed port 14 is consistent during each test. Since a part of the polymer facing mortar is higher than the port of the storage port 31, part of the polymer facing mortar will fall from the storage port 31 each time. If the tested polymer facing mortar is easy to collapse, more material heads will fall on the material loading plate 310, and the value received by the gravity receiver 35 will be large. Otherwise, the value received by the gravity receiver 35 will be small. By testing the weight of the fallen polymer facing mortar, the slump value of the polymer facing mortar can be obtained.

[0042] An adjustable valve 312 is provided at the lower part of the storage port 31, and a feeding cylinder 311 is provided at the lower part of the adjustable valve 312. When the adjustable valve 312 is opened, the polymer facing mortar placed in the storage port 31 will slide into the feeding cylinder 311. A waste collecting device is externally connected to the lower part of the feeding cylinder 311, and the polymer facing mortar after detection will eventually be collected. A first baffle plate 32 is provided on the outer side of the material loading plate 310, and the first baffle plate 32 is used to limit the overflow of the polymer facing mortar. A second baffle plate 39 is provided on the inner side of the material loading plate 310, and a plurality of pull rods 38 are also provided at the lower part of the second baffle plate 39. A cylinder 36 is provided at the lower part of each pull rod 38. The first baffle plate 32 is fixedly connected to the material loading plate 310, and the second baffle plate 39 is movably connected to the material loading plate 310. The cylinder 36 will drive the pull rod 38 to retract downward, and the pull rod 38 will then drive the second baffle plate 39 to move downward.

[0043] When part of the polymer facing mortar in the storage port 31 falls on the material placing plate 310, after the gravity receiver 35 analyzes the data, the cylinder 36 will drive the pull rod 38 to retract downward, thereby driving the second material baffle plate 39 to move downward. Because the material placing plate 310 is configured to be higher on the outside and lower on the inside, the polymer facing mortar will slowly accumulate on the inner side of the material placing plate 310 under the action of gravity. As the second material baffle plate 39 moves downward, the second material baffle plate 39 will drop to a position lower than the material placing plate 310. At this time, the polymer facing mortar will slide from the inner side of the material placing plate 310. A limiting plate 37 is provided at the lower part of the material placing plate 310. The polymer facing mortar sliding from the inner side of the material placing plate 310 will enter the limiting plate 37. A waste collecting device is also provided at the lower part of the limiting plate 37. The polymer facing mortar entering the limiting plate 37 will eventually enter the waste collecting device and be collected.

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the embodiment of the present invention provides a polymer plaster mortar slump detection device, including a detection device housing 21, a water pipeline 22, a pressurized base 23, a water reservoir 24, a water nozzle 25 and a laser rangefinder 26.

[0045] In the embodiment of the present invention, the test housing 2 is arranged outside the detection device 3, and the test housing 2 is used for testing and cleaning the polymer plastering mortar to be tested.

[0046] A plurality of laser rangefinders 26 are arranged inside the detection device housing 21. The plurality of laser rangefinders 26 will work when the polymer facing mortar is put into the storage port 31. The laser rangefinder 26 will record the height of the polymer facing mortar when it is just put into the storage port 31. After a certain period of time, the laser rangefinder 26 will record the height of the polymer facing mortar at this time. By recording the height difference of the polymer facing mortar slump within a certain period of time, the slump of the polymer facing mortar can be further detected. That is, if the slump of the polymer facing mortar is small, the result obtained by the laser rangefinder 26 will be small. If the slump of the polymer facing mortar is large, the result obtained by the laser rangefinder 26 will be large. The numerical value obtained by the laser rangefinder 26 can clearly present the slump of the polymer facing mortar.

[0047] A plurality of water spray nozzles 25 are also provided inside the detection device housing 21. Each water spray nozzle 25 is connected to an external water pipe 22. The water pipe 22 is connected to a pressurized base 23. A water reservoir 24 is provided at the lower part of the pressurized base 23. The water flow in the water reservoir 24 will generate a higher flow rate through the pressurization of the pressurized base 23. Then the water flows through the water pipe 22 and is finally sprayed out from the water spray nozzle 25. The water spray nozzle 25 is provided outside the detection device 3 and is arranged in a ring shape, so that the water sprayed from the water spray nozzle 25 can cover the periphery of the detection device 3 360°, forming a cleaning without dead angles.

[0048] When the detection device 3 completes the slump detection of the polymer plaster mortar, the adjustable valve 312 is kept open and the second material baffle plate 39 is kept falling, and then the water nozzle 25 sprays water to the detection device 3. With the high-pressure water flow sprayed from the water nozzle 25, the polymer plaster mortar remaining on the material plate 310 and the storage port 31 in the detection device 3 can be washed away by the water flow, eliminating the problem of manual cleaning of the equipment after testing the product.

[0050] In the embodiment of the present invention, the feeding device 1 is arranged on the upper part of the detection device 3, and the feeding device 1 is used to configure and convey the polymer plastering mortar.

[0051] A feed port 13 is provided at the upper portion of the feed hood 11, and the raw materials of the polymer facing mortar are input into the interior of the feed hood 11 from the feed port 13. Similarly, a water supply device 12 is provided at the upper portion of the feed hood 11, and the water supply device 12 is provided at one side of the feed port 13. The feed port 13 is configured in a funnel shape, which is beneficial to the entry of the raw materials of the polymer facing mortar. The water supply device 12 provided at one side of the feed port 13 can spray water into the interior of the feed hood 11. A stirring device is provided inside the feed hood 11, so that the raw materials of the polymer facing mortar placed in the interior of the feed hood 11 can be fully stirred. The proportioned polymer facing mortar will enter the storage port 31 through a feed discharge port 14 provided at the lower portion of the feed hood 11. The size of the feed discharge port 14 is slightly smaller than the storage port 31, and the volume of the polymer facing mortar proportioned each time is the same.
