[0021] Combined with reference Figure 1-Figure 4 The utility model provides a raw material mixer, including a foaming mixing box 1, the top of the foaming mixing box 1 is rotatably connected to a box cover 2 through a hinge, a handle can be provided on the box cover 2, a discharge port 21 is provided at the bottom of the foaming mixing box 1, a valve can be provided on the discharge port 21, a vertical cylinder 3 is fixedly mounted on the inner wall of the foaming mixing box 1, and a material guiding section is reserved between the bottom of the vertical cylinder 3 and the inner bottom of the foaming mixing box 1, the material guiding section can provide a material guiding channel for the foaming raw materials transported through the vertical cylinder 3, so that the foaming raw materials can be conveniently moved from top to bottom, a driving rod 4 is provided in the vertical cylinder 3, an auxiliary support member 5 is rotatably connected to the driving rod 4, the auxiliary support member 5 is movably connected to the vertical cylinder 3, and a transmission assembly 6 is provided on the driving rod 4.

[0022] The transmission assembly 6 includes a transmission concave block 61 fixedly connected to the top of the driving rod 4 and a transmission protrusion 62 movably inserted on the transmission concave block 61. The transmission protrusion 62 is rotatably connected to the bottom position of the box cover 2 through a rotating shaft. A stirring motor 7 for driving the transmission protrusion 62 to rotate is arranged on the top of the box cover 2. The power output end of the stirring motor 7 can drive the transmission protrusion 62 to rotate through the rotating shaft. When the transmission protrusion 62 is inserted into the transmission concave block 61, that is, the box cover 2 is closed on the foaming mixing box 1, the stirring motor 7 can drive the driving rod 4 to stir and rotate. The outer surface of the driving rod 4 is fixedly connected with a spiral auger 8. The rotation of the driving rod 4 can drive the spiral auger 8 to rotate in the vertical cylinder 3. By using the conveying pipeline provided by the vertical cylinder 3, the foaming raw materials in the foaming mixing box 1 can be conveyed from the top to the bottom of the vertical cylinder 3, so that the foaming raw materials can achieve an up and down surging effect. The spiral auger 8 is located in the vertical cylinder 3. The outer surface of the driving rod 4 is also fixedly connected with a stirring assembly 9, and the stirring assembly 9 is located on the outside of the vertical cylinder 3.

[0023] The bottom end of the vertical tube 3 is fixedly connected with a fixing rod 12 , and the fixing rod 12 is fixedly connected to the inner bottom position of the foaming mixing box 1 , and the fixing rod 12 can improve the stability of the erection of the vertical tube 3 .

[0024] The auxiliary support member 5 includes a support plate 51 rotatably connected to the outer surface of the driving rod 4 and at least one pair of positioning columns 52 fixedly connected to the bottom of the support plate 51. The positioning columns 52 are movably inserted into the top end surface of the vertical tube 3. The top end surface of the vertical tube 3 is provided with a slot for inserting the positioning columns 52.

[0025] Specifically, when the driving rod 4 extends into the vertical tube 3 , the positioning column 52 can be firstly inserted into the slot, so that the position of the driving rod 4 can be vertically limited, thereby ensuring the stability of the driving rod 4 when rotating.

[0026] The stirring assembly 9 includes a fixed plate 91 fixedly connected to the outer surface of the driving rod 4, two pairs of brackets 92 fixedly connected to the outer surface of the fixed plate 91 and a spiral stirring blade 93 fixedly connected to the two pairs of brackets 92. A plurality of cross braces 13 are fixedly connected to the brackets 92 and the spiral stirring blades 93. The cross braces 13 can be used to reinforce the position of the spiral stirring blades 93. At the same time, when the cross braces 13 rotate, they can stir the foaming raw materials.

[0027] Specifically, when the driving rod 4 is vertically confined in the vertical cylinder 3, the spiral auger 8 and the stirring assembly 9 on the driving rod 4 can be respectively located at the inner and outer sides of the vertical cylinder 3. When the driving rod 4 rotates, the spiral auger 8 can rotate in the vertical cylinder 3, and the foaming raw materials in the foaming mixing box 1 can enter through the top of the vertical cylinder 3 and be transported by the spiral auger 8. In this way, the foaming raw materials can flow up and down continuously and cyclically. At the same time, the synchronous rotation of the spiral stirring blade 93 can continue to stir the foaming raw materials in a circular manner. The above two methods are used to stir the foaming raw materials, and the stirring is thorough and the mixing effect is good. This can improve the stirring quality of the foaming raw materials and improve the stirring efficiency.

[0028] It is worth noting that when the drive rod 4 and the structure thereon need to be removed, the box cover 2 can be opened, at which time the transmission protrusion 62 and the transmission recess 61 are disconnected, and the structure can be removed by vertically pulling the drive rod 4 for subsequent cleaning work.

[0029] The outer surface of the vertical cylinder 3 is fixedly connected with a balance plate 10 for the movably inserted bracket 92. In the present application, a limiting groove for the movably inserted bracket 92 is provided on the balance plate 10. When the positioning column 52 is inserted into the slot, the bracket 92 can be vertically inserted into the limiting groove of the balance plate 10. In this way, when the spiral stirring blade 93 rotates, the stability of the centrifugal rotation of the bracket 92 can be improved.

[0030] The bottom of the foaming and mixing box 1 is fixedly connected with a support leg 11 , which can be used to support the height of the foaming and mixing box 1 , so as to facilitate the discharge of materials from the discharge port 21 .
