It includes a bearing mechanism, and the main body of the bearing mechanism is a rectangular parallelepiped structure design. In the utility model, it can be rotated by starting the auxiliary component installed on the inner side of the discharging component, and the main body of the auxiliary component is a transmission shaft structure design with spiral crushing teeth. The two auxiliary components are arranged in a horizontal array, and then when the material falls into it, it can be re-mixed and the internal lumps can be broken by the spiral crushing teeth."
[0003] However, although the prior art discharging device for preparing polyurethane epoxy synthesis achieves the effect of re-mixing and accelerating the discharge, it still has some shortcomings: the prior art discharging device for preparing polyurethane epoxy synthesis requires that the mixed materials fall evenly above the discharge component involved in the device, while the discharge port of the prior art mixing container generally does not have the function of uniform discharge, resulting in the inability to uniformly perform the re-mixing and crushing operation; secondly, the driving component and the extrusion component are mutually squeezed by the inclined surfaces, and the material will also move to the upper side of the inclined surface after being subjected to force between the inclined surfaces, so the effect of accelerating the discharge downward by squeezing is not obvious.

[0008] Furthermore, the pressing piece is configured as a cone structure, with the tip of the cone facing upward, and the width of the cone is smaller than the width of the inner cavity of the discharge section.
[0009] Furthermore, the material leveling member includes a material leveling hopper, and a connecting plate is provided at the upper edge of the material leveling hopper, and a horizontal guide hole is opened inside the connecting plate.
[0010] Furthermore, the upper and lower ends of the equalizing hopper are both configured as rectangular open structures, and the width of the rectangular opening on the lower side is smaller than that of the rectangular opening on the upper side.
[0011] Furthermore, a cavity is provided inside the discharge section, and a movable groove is provided outside the cavity and at the bottom of the discharge section. The connecting plate is slidably connected in the movable groove, and a guide rod is installed in the movable groove. At the same time, the guide rod slides through the guide hole, and a spring is provided on the outside of the connecting plate and sleeved on the outside of the guide rod.

[0014] 2. During the discharging process, due to the forward and reverse rotation of the threaded stirring shaft, the threaded block screwed to it moves up and down, and then drives the pressing piece to move up and down. When the pressing piece moves upward, the gap with the inner wall of the synthesizer increases, and the raw materials slide downward. When the pressing piece moves downward, the gap with the inner wall of the synthesizer becomes smaller, and then the material on the lower side is vertically pressed down. At this time, the raw materials have only a tendency to move downward, and then cooperate with the anti-blocking effect of the spiral stirring blades to speed up the discharging efficiency.

[0022] In this embodiment, the synthesizer 1 and the material distribution member 2 constitute the main structure of the device for preparing polyurethane epoxy synthesis and discharging involved in this application, which is used for preparing the synthesis and discharging process of polyurethane materials.
[0023] Specifically, an arc-shaped contact block is provided on the outer side of the material equalizing piece 2, and the arc opening of the contact block faces the vibrator 3, and the vibrating end of the vibrator 3 is connected to a horizontal rod, and the other end of the horizontal rod is set to an arc structure, and collides and contacts with the outer arc opening of the contact block, wherein the vibrator 3 is fixed on the supporting leg of the outer wall of the synthesizer 1.
[0024] Specifically, a portion between the discharge section 11 and the synthesizer 1 is set as a tapered section, and an electric valve is installed in the discharge section 11.
[0025] As a preferred embodiment, the spiral stirring blade 14 is provided so that when driven by the rotating shaft 18, on the one hand, a stirring and mixing effect can be achieved inside the discharge section 11, and on the other hand, blockage can be prevented from occurring inside the discharge section 11 during discharge.
[0026] like Figure 2 and Figure 3 As shown, a motor is installed on the top of the synthesizer 1, and the upper end of the threaded stirring shaft 12 is connected to the output shaft end of the motor, and inclined stirring blades are welded on the outer side of the threaded stirring shaft 12, the outer wall of the threaded tube 15 is vertically slidably connected to a guide ring 17, and the outer wall of the guide ring 17 is connected to a fixing rod 16, and the outer end of the fixing rod 16 is fixed to the inner wall of the synthesizer 1, the pressing piece 13 is set to a cone structure, and the tip of the cone is facing upward, and the width of the cone is smaller than the width of the inner cavity of the discharge section 11.
[0027] Specifically, the guide ring 17 uses existing technology to achieve an up and down sliding connection with the threaded tube 15 while keeping the threaded tube 15 itself from rotating, thereby achieving the up and down movement of the threaded tube 15 while the threaded stirring shaft 12 rotates, and the upper and lower ports of the threaded tube 15 do not exceed the guide ring 17 when the threaded tube 15 moves up and down.
[0028] As a preferred embodiment, by providing the material pressing piece 13 and cooperating with the conical section on the upper side of the discharge section 11, the material pressing piece 13 has a material dispersing effect during its ascending process and has a material pressing effect during its descending process.
[0029] like Figure 4 and Figure 5 As shown, the material equalizing member 2 includes a material equalizing hopper 21, and a connecting plate 22 is provided at the upper edge of the material equalizing hopper 21, and a horizontal guide hole 23 is opened inside the connecting plate 22, the upper and lower ends of the material equalizing hopper 21 are both set as rectangular open structures, and the width of the rectangular opening on the lower side is smaller than that of the rectangular opening on the upper side, a cavity is provided inside the discharge section 11, and a movable groove 111 is opened outside the cavity and at the bottom of the discharge section 11, the connecting plate 22 is slidably connected in the movable groove 111, and a guide rod 113 is installed in the movable groove 111, and the guide rod 113 slides through the guide hole 23, and a spring 112 is provided on the outside of the connecting plate 22 and is sleeved on the outside of the guide rod 113.
[0030] Specifically, the area of the upper port of the equalizing hopper 21 is larger than the lower port of the discharge section 11, so that the mixed material can fall directly into the equalizing hopper 21. At the same time, the front cross-section of the equalizing hopper 21 is set to an isosceles trapezoidal structure, so that the amount of the upper raw material is kept sufficient while the raw material slides downward, that is, the raw material in the lower layer is gradually squeezed and then discharged through the open port on the lower side of the equalizing hopper 21 to maintain good continuity.
[0031] As a preferred embodiment, by providing the movable groove 111, the spring 112 and the guide rod 113, the vibration effect of the equalizing hopper 21 can be achieved during the vibration of the vibrator 3, thereby accelerating the diffusion effect of the mixed material inside the equalizing hopper 21.
[0032] like Figure 1 It should be noted that a discharging device as mentioned in the comparison can be provided at the lower end of the material distributing member 2, so that after obtaining the effect of uniform discharging, a further mixing and crushing effect can be achieved.
[0033] When in use, a motor is used to drive the threaded stirring shaft to reciprocate forward and reverse, and at the same time drive the rotating shaft to rotate, thereby achieving a stirring effect on the polyurethane synthetic material inside the synthesizer, and then the valve inside the discharge section is opened, and the motor is kept running, so that the internal raw materials slide down into the material equalizing piece, and at the same time the vibrator outside the material equalizing piece is started, so that the falling raw materials are vibrated and diffused through the vibration of the material equalizing hopper, so that the raw materials fall evenly from the lower side of the material equalizing hopper; during the discharge process, due to the forward and reverse rotation of the threaded stirring shaft, the threaded block screwed thereto is driven to move up and down, and then the material pressing piece is driven to move up and down.

When the material pressing piece moves downward, the gap with the inner wall of the synthesizer becomes smaller, thereby having the effect of vertically pressing down the material on the lower side.
[0034] The utility model is used for preparing polyurethane epoxy synthesis discharging device and can effectively solve the problem that the existing polyurethane epoxy synthesis discharging device does not have the uniform diffusion discharging function and the effect of accelerating the discharging is not obvious. It realizes the uniform diffusion discharging function and the anti-blocking effect and the obvious acceleration of the discharging effect on the basis of the existing technology of the polyurethane epoxy synthesis discharging device, thereby enhancing the practicability of the device.
