Technical Field
[0001] This utility model belongs to the field of material preparation equipment technology, specifically relating to a manual polyurea plastic surface material processing device. Background Technology
[0002] Currently, the application scope of sprayed polyurea elastomer products is expanding rapidly, with wide applications in steel structure corrosion protection, concrete protection, roof waterproofing and insulation, pool lining, industrial flooring, urban overpass protection, port facilities, hydropower projects, and nuclear power projects. Important projects in my country that have already applied sprayed polyurea technology include the Beijing-Tianjin High-Speed Railway, the National Olympic venues, Yangshan Deep-Water Port, Shanghai World Expo venues, and the Shanghai Bund transportation corridor, among other large-scale infrastructure projects. The ongoing construction of the Beijing-Shanghai High-Speed Railway will also fully utilize this advanced technology for track concrete protection. In terms of corrosion resistance and environmental protection, polyurea elastomers have demonstrated significant technological and market advantages and are receiving increasing attention.
[0003] CN108126840A discloses an environmentally friendly handmade polyurea plastic surface material processing device and preparation method, comprising a vehicle body with a handle horizontally fixed to the left side; a base plate located directly below the vehicle body; a first liquid storage tank fixed to the upper right side of the vehicle body; a second liquid storage tank fixed to the left side of the first liquid storage tank and above the vehicle body; a first lifting pump located at the center of the bottom of the first liquid storage tank; a second lifting pump fixed at the center of the lower end of the second liquid storage tank; a transport pipe vertically fixed to the center of the center directly above the first and second lifting pumps, the transport pipe being serpentine; a heating box located above the first and second liquid storage tanks; and a fixing block located at the center of the center of the upper end of the heating box. When the user turns on the first and second lifting pumps to transport the material to the spray gun, they rotate the turntables to align the perforations on the two turntables, allowing the two materials to enter the mixing chamber in a mist form and mix rapidly; the mixed material is then sprayed out through the nozzle.
[0004] However, the above-mentioned processing device requires rotating the turntables so that the perforations on the two turntables correspond to each other in order to spray out the material. When spraying is not required, there is no limit between the two turntables, and the material is easy to be sprayed out accidentally. Utility Model Content
[0005] The purpose of this invention is to provide a manual polyurea plastic surface material processing device to prevent the material from being easily sprayed out.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a manual polyurea plastic surface material processing device, comprising:
[0007] The base plate has casters fixed to its lower side.

[0011] The second pump has a second pumping inlet connected to the second storage chamber, and a second pumping outlet connected to a second rigid tube. The end of the second rigid tube away from the second pumping outlet is connected to a second flexible tube.
[0012] The nozzle has a mixing chamber inside, one end of which has a first connecting hole and a second connecting hole, and the other end has a spray outlet. The first connecting hole and the second connecting hole are respectively connected to the first hose and the second hose. The side wall of the mixing chamber has a side sliding groove.
[0013] The pressing rod is inserted into the side sliding groove. A blocking block is fixed to one end of the pressing rod located in the mixing chamber, and a pressing plate is fixed to one end of the pressing rod located outside the nozzle.
[0014] A reset spring is sleeved on the pressing rod and disposed between the pressing plate and the outer wall of the nozzle. When the reset spring is in its original length state, the blocking block blocks the first connecting hole and the second connecting hole.
[0015] Furthermore, a fixing rod is fixed on the outer wall of the nozzle, the fixing rod is positioned above the pressing rod, the fixing rod is provided with a T-slot, a slider is installed in the T-slot, a push rod extending out of the T-slot is fixed on the slider, and a threaded hole is provided on the side of the T-slot away from the nozzle, and a positioning screw is threadedly connected to the threaded hole.
[0016] Furthermore, the mixing cavity is provided with a groove, and when the blocking block is inserted into the groove, the blocking block opens the first connecting hole and the second connecting hole.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-7 This utility model provides a technical solution for a manual polyurea plastic surface material processing device.
[0033] A hand-operated polyurea plastic surface material processing device, comprising:
[0034] Base plate 1, with casters 2 fixed to the lower side of base plate 1;
[0035] The first liquid storage tank 3 is fixed to the upper side of the base plate 1, and the first liquid storage tank 3 is provided with a first liquid storage cavity 4.
[0036] The second liquid storage tank 5 is fixed to the upper side of the base plate 1, and the second liquid storage tank 5 is provided with a second liquid storage cavity 6.
[0037] The first liquid pump 7 has a first liquid inlet connected to the first liquid storage chamber 4, and a first liquid outlet connected to the first rigid tube 8. The end of the first rigid tube 8 away from the first liquid outlet is connected to a first flexible tube 9.
[0038] The second liquid pump 10 has a second liquid inlet connected to the second liquid storage chamber 6, and a second liquid outlet connected to a second rigid tube 11. The end of the second rigid tube 11 away from the second liquid outlet is connected to a second flexible tube 12.
[0039] The nozzle 13, the first hose 9, and the second hose 12 are all fixedly connected to the nozzle 13. The nozzle 13 is provided with a mixing chamber 14. One end of the mixing chamber 14 is provided with a first connecting hole 15 and a second connecting hole 16, and the other end is provided with a spray outlet 17. The first connecting hole 15 and the second connecting hole 16 are respectively connected to the first hose 9 and the second hose 12. The side wall of the mixing chamber 14 is provided with a side sliding groove 18.
[0040] Pressing rod 19 is inserted into side slide groove 18. One end of pressing rod 19 located inside mixing chamber 14 is fixed with a blocking block 20, and the other end of pressing rod 19 located outside nozzle 13 is fixed with pressing plate 21.
[0041] The reset spring 22 is sleeved on the pressing rod 19 and is located between the pressing plate 21 and the outer wall of the nozzle 13. When the reset spring 22 is in its original length state, the blocking block 20 blocks the first connecting hole 15 and the second connecting hole 16.
[0042] In use, push the base plate 1 to the destination, then turn on the first liquid pump 7 and the second liquid pump 10. The first liquid pump 7 draws out liquid A from the first liquid storage chamber 4, and the second liquid pump 10 draws out liquid R from the second liquid storage chamber 6. The user presses the pressing plate 21, which moves the blocking block 20. The blocking block 20 moves out of the first connecting hole 15 and the second connecting hole 16. Liquid A and liquid R enter the mixing chamber 14 from the first connecting hole 15 and the second connecting hole 16 respectively, and are sprayed out from the spray outlet 17 after mixing. Therefore, simply pressing the pressing plate 21 will spray out the mixture and form a polyurea plastic surface layer, which is very convenient to operate. When it is necessary to block the first connecting hole 15 and the second connecting hole 16, simply release the pressing plate 21, and the return spring 22 will return to its original length, thereby driving the blocking block 20 to block the first connecting hole 15 and the second connecting hole 16. This can limit the blocking block 20 and prevent it from moving randomly.
[0043] like Figure 5 As shown, a fixing rod 23 is fixed on the outer wall of the nozzle 13. The fixing rod 23 is positioned above the pressing rod 19. The fixing rod 23 has a T-slot 24. A slider 25 is installed in the T-slot 24. A push rod 26 extending out of the T-slot 24 is fixed on the slider 25. The push rod 26 is located on the side of the pressing plate 21 facing away from the nozzle 13. A threaded hole 27 is provided on the side of the T-slot 24 away from the nozzle 13. A positioning screw 28 is threadedly connected to the threaded hole 27.
[0044] In some cases, if the user wants to continuously spray the mixture, they can rotate the positioning screw 28. The positioning screw 28 drives the slider 25 to move towards the nozzle 13, thereby causing the push rod 26 to drive the pressing plate 21 to move towards the nozzle 13. This eliminates the need to continuously press the pressing plate 21, meeting the user's needs in different practical situations.
[0045] like Figure 5 As shown, the mixing cavity 14 is provided with a groove 29. When the blocking block 20 is inserted into the groove 29, the blocking block 20 opens the first connecting hole 15 and the second connecting hole 16, and the groove 29 serves to accommodate the blocking block 20.
[0046] like Figure 1 As shown, a support vertical plate 30 is fixed to one end of the base plate 1, and a handle 31 is fixed on the support vertical plate 30. The entire processing device can be moved by pushing the handle 31, which is very convenient.
[0047] like Figure 1 As shown, heating wires 32 are spirally wound on the outer walls of the first rigid tube 8 and the second rigid tube 11. The heating wires 32 can generate heat, thereby heating the liquid flowing through the first rigid tube 8 and the second rigid tube 11. Of course, a heat insulation pad can also be wrapped around the outside of the heating wires 32.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
