Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a raw material mixing and stirring equipment. Background Technology

[0002] Most washing machine lids are currently made of plastic. However, there are a few washing machine lids on the market that are made of biomass materials such as wood flour, straw powder, or rice husk powder. Washing machine lids made of biomass materials are not only environmentally friendly and biodegradable, but also sturdy and durable.

[0003] In the process of manufacturing washing machine top covers from straw, the raw material needs to be crushed by a crusher. The crushed raw material is then sieved by a screening device to obtain 60-250 mesh powder, which is then classified and stored. The classified 60-250 mesh raw material powder is then mixed with adhesive. The washing machine top cover produced in this way not only has high strength but also a high surface smoothness. Currently, when mixing the raw material powder, 60 mesh powder and 250 mesh powder are simultaneously fed and directly mixed with adhesive. This easily leads to insufficient mixing between the 60 mesh powder and 250 mesh powder, resulting in uneven mixing after direct mixing with adhesive.

[0004] In summary, there is a need for a raw material mixing and stirring device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a raw material mixing and stirring device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A raw material mixing and stirring device includes a mixing chamber, with two discharge pipes at the lower end of the mixing chamber connected to a collection hopper. The lower end of the collection hopper is connected to a conveying pipe, and a discharge pipe is located near the left side of the lower end of the conveying pipe. An external connecting pipe is installed through the upper end of the conveying pipe and connected to a spray pipe. An auger is rotatably connected to the inner wall of the conveying pipe. The right end of the auger passes through the conveying pipe and is connected to a drive shaft via a toothed belt. The drive shaft is connected to the output shaft of a first motor.

[0008] Furthermore, the mixing chamber includes a cavity, and two cavities are opened inside the mixing chamber. A mixing shaft is rotatably connected through the top of the cavity. The mixing shaft is connected to the output shaft of a second motor through a bevel gear set. The second motor is located at the upper end of the mixing chamber.

[0009] Furthermore, the mixing chamber also includes mixing blades, and the mixing blades and spiral blades are fixedly arranged on the outer ring of the mixing shaft, with the spiral blades arranged below the mixing blades.

[0010] Furthermore, the mixing chamber also includes a material distribution valve. Two material distribution valves are provided above the mixing chamber. The upper end of the front material distribution valve is connected to a first feeding pipe, and the lower part of the front material distribution valve is connected to two first connecting pipes. The two first connecting pipes are respectively connected to a chamber.

[0011] Furthermore, the mixing chamber also includes a second feeding pipe. The upper end of the rear distribution valve is connected to the second feeding pipe, and two second connecting pipes are connected below the rear distribution valve. The two second connecting pipes are respectively connected to a chamber.

[0012] Furthermore, the mixing chamber also includes a rotating shaft, which is rotatably connected to the inner wall of the distributing valve. The inner end of the rotating shaft is connected to a valve plate, and one side of the rotating shaft passes through the distributing valve and is connected to the output shaft of the third motor.

[0013] This utility model provides a raw material mixing and stirring device. Compared with the prior art, it has the following advantages:

[0014] First, 60-mesh powder and 250-mesh powder are fed into the left chamber via the first and second feeding pipes, respectively, through the distribution valve and the first and second connecting pipes on the left side. This pre-mixing process ensures thorough mixing of the 60-mesh and 250-mesh powders. The mixed powder is then discharged into the conveying pipe through the corresponding discharge pipe. Under the action of the auger, the mixed powder is conveyed. Simultaneously, external adhesive is sprayed through the spray pipe and mixed with the powder via the external pipe. At the same time, the valve plate is rotated and adjusted by the third motor and the rotating shaft, allowing the first and second feeding pipes to feed the 60-mesh and 250-mesh powders into the right chamber via the distribution valve and the first and second connecting pipes on the right side. This pre-mixing process continues until the mixed powder in the left chamber is discharged, and the powder in the right chamber is fully mixed. This process helps improve mixing efficiency.

[0037] Working principle and usage process of this utility model:

[0038] In use:

[0039] Step 1: 60-mesh powder and 250-mesh powder are fed into the left chamber 101 through the first feeding pipe 108 and the second feeding pipe 110, respectively, via the dispensing valve 107, the first connecting pipe 109 on the left, and the second connecting pipe 111 on the left.
