[0037] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0041] The homogenizing frame is located at one end of the material storage section 1, and the discharge end 111 is connected to the homogenizing frame. The homogenizing frame includes a main body 21 and a tower cover 22, and the tower cover 22 is pyramid-shaped.

[0042] Among them, multiple diversion holes 221 are arrayed on the multi-layer end faces of the single-layer tower cover 22.

[0043] As can be seen from this embodiment, a mixing and dispensing device for polyurethane adhesive production includes a material storage section 1 and a homogenizing frame;

[0044] The material storage section 1 is provided with a discharge end 111 and a feed port 121. A homogenizing frame is installed on the discharge end 111. The homogenizing frame includes a main body 21 and a tower cover 22.

[0045] One end of the main body 21 is connected to the discharge end 111 on the storage section 1, and the other end is connected to a multi-layer bottom plate. The tower cover 22 is pyramid-shaped. Furthermore, each layer of the tower cover 22 has an array of diversion holes 221.

[0046] By setting a pyramid-shaped tower cover 22 and equidistantly arraying multiple diversion holes 221 on the end face of each layer of the tower cover 22, the raw materials can be effectively separated, and the multiple streams of fluid flowing out from the pyramid-shaped tower cover 22 are less likely to merge, so that the raw materials can flow evenly to the external stirring device, thereby helping to improve the stirring effect.

[0047] Multiple raw materials form a premixed solution within the main body 21, and are evenly distributed to an external stirring device for processing via a homogenizing frame. Premixing multiple raw materials in advance during the feeding process helps improve production efficiency.

[0057] The discharge end 111 is formed on the front end plate 11, the feed port 121 is formed on the rear end plate 12, the membrane tube 13 is made of a flexible film bag, and furthermore, the feed port 121 is connected to the end cap 3, and the end cap 3 is threadedly connected to the feed port 121.

[0058] During use, the raw material stored inside can be squeezed out from the discharge end 111 through the extrusion tube 13 and diverted when passing through the homogenizing frame.

[0059] Example 3:

[0060] This embodiment provides a mixing and dispensing device for polyurethane adhesive production, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

The other end of the cylinder 211 is closed, and a through hole is provided on the closed end face. The discharge end 111 is connected to the inside of the cylinder 211 through the through hole.

[0067] The skirt frame 212 is formed at the bottom of the cylinder 211, and multiple first connecting holes 2121 are formed on the skirt frame 212.

The output part of the booster 4 is located inside the membrane cylinder 13. At the mounting port of the booster 4, the compressor injects external air into the membrane cylinder 13. After the raw material in the membrane cylinder 13 is squeezed by the incoming air, it enters the homogenizing frame body from the discharge end 111 and is diverted.

[0074] Furthermore, the homogenizing frame connected to multiple material storage sections 1 can change the flow rate of raw materials entering the membrane cylinder 13 by changing the amount of air injected into the membrane cylinder 13 by different boosters 4, thereby achieving the effect of controlling the composition of components.

[0085] The membrane tube 13 is bonded and fixed at both ends to the first protrusion 114 and the second protrusion 122.

[0086] As can be seen from this embodiment, by providing a first protrusion 114 and a second protrusion 122 on the mating surfaces of the front end plate 11, the rear end plate 12 and the membrane tube 13, it helps to expand the connection mating surfaces between the front end plate 11, the rear end plate 12 and the membrane tube 13, thereby making the connection between the membrane tube 13 and the first protrusion 114 and the second protrusion 122 more stable.

By setting the protrusion 5, the connecting mating surface between the first boss 114 and the second boss 122 can be further enlarged, thereby improving the connection. At the same time, after the protrusion 5 and the membrane tube 13 are fused together, they will form a corner fit. The corner fit forms a limit, making the connection between the membrane tube 13 and the first boss 114 and the second boss 122 stable. Meanwhile, the protrusion 5 forms multiple partitions on the wall surface of the first boss 114 and the second boss 122, which helps to improve the sealing effect.
