[0026] The following will refer to the appendix in the embodiments of this utility model. Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] like Figures 1 to 8The utility model discloses a kind of polyurethane color adding pouring devices, including pouring seat body 1, mixing cavity 11 is equipped in pouring seat body 1, feed seat body 2 is fixed on the upside of pouring seat body 1, the left and right sides of this feed seat body 2 are all opened with the inlet 21 that reaches mixing cavity 11, and, the left and right sides of feed seat body 2 are also all equipped with switch valve 3, material cavity 31 is opened in switch valve 3, and switch valve 3 is also opened with the communication port 32 for connecting material cavity 31 and inlet 21, in addition, material guide device 4 is equipped in the upside of switch valve 3, and material guide device 4 has a plurality of material ports 41, and switch valve core 5 is rotatably arranged in material cavity 31 in switch valve 3, and switch valve core 5 is used to switch different material ports 41 to be connected to communication port 32 in the rotating process. By being equipped with switch valve 3 and its internal switch valve core 5 of the left and right sides of feed seat body 2, the quick switching between different polyurethane materials can be realized. This design makes it unnecessary to frequently change pouring head in production process, thereby significantly improve production efficiency.

[0029] Further, discharge nozzle 6 is fixedly connected on the downside of feed seat body 2, discharge nozzle 6 is used for polyurethane material to spray out, and plug 61 is movably arranged on feed seat body 2, plug 61 is used to block discharge nozzle 6, control cylinder 62 for driving plug 61 to slide up and down is equipped on feed seat body 2, by the arrangement of plug 61 and control cylinder 62, it is ensured that material flow amount can be effectively controlled.

[0030] In the utility model, switch valve core 5 penetrates switch valve 3 forward and is fixedly connected with driven gear 51, and second control cylinder 7 is fixedly connected outside control cylinder 62, and rack 71 for being engaged with driven gear 51 is fixedly connected on the piston rod of second control cylinder 7, by the engagement of driven gear 51 and rack 71 on second control cylinder 7, the automatic operation in the rotating process of switch valve core 5 is realized. In this way, not only operation process is simplified, error risk caused by human factor is reduced, but also work efficiency is further improved.

[0031] Specifically, two material inlets 41 are provided on the material inlet device 4, and an arc-shaped groove 52 is provided on one side of the unique connecting port 32 on the switching valve core 5. A first transverse groove 53, axially connected to the arc-shaped groove 52, is also provided on the outer wall of the switching valve core 5. The arc-shaped groove 52 is located below one of the material inlets 41, and the first transverse groove 53 is located below the other material inlet 41. Additionally, a secondary material inlet 33 is provided on the rear side of the switching valve 3, and a secondary injection port 54 extends from the rear end to one side of the connecting port 32. This secondary injection port 54 corresponds to the secondary material inlet 33. Therefore, during use, the two material inlets 41 and the secondary material inlet 33 can be connected to the polyurethane material transmission pipe as needed. When the switching valve core 5 is rotated, when the secondary injection port 54 corresponds to the connecting port 32, the material entering the secondary injection port 54 from the secondary material inlet 33 flows into the mixing chamber 11 from the connecting port 32. At this time, the arc-shaped groove 5... Since the material inlet 41 is not allowed to enter the mixing chamber 11, the material inlet 2 is offset from the connecting port 32. When the switching valve core 5 is rotated so that the arc groove 52 corresponds to the connecting port 32 and the first horizontal groove 53 is offset from the material inlet 41 above it, only the material in the material inlet 41 above the arc groove 52 can enter the mixing chamber 11. Since the arc groove 52 corresponds to the connecting port 32 and the first horizontal groove 53 corresponds to the material inlet 41 above it, the material entering from the two material inlets 41 will mix together and enter the mixing chamber 11.

[0032] like Figure 5 As shown, several color-adding valves 8 are fixedly connected to the outside of the casting base 1. Each color-adding valve 8 includes a valve body 81, a telescopic cylinder 82, a color-adding connector 83, and a pin 85. The casting base 1 has several color-adding ports 12 leading to the mixing chamber 11. Each valve body 81 is connected to a different color-adding port 12. The color-adding connector 83 is connected to the valve body 81 and has a color-adding channel 84 that leads into the valve body 81. The pin 85 is movably disposed inside the valve body 81. The telescopic cylinder 82 is connected to the pin 85. The pin 85 is used to open and close the color-adding function. The pigment enters the valve body 81 from the color-adding channel 84 of the color-adding connector 83, and then enters the mixing chamber 11 through the color-adding ports 12. In this utility model, seven color-adding valves 8 are provided on the outside of the casting base 1, which can achieve a more uniform color-adding effect.
