Description

Technical Field

[0001] The utility model relates to the technical field of screw mixing equipment, in particular to an auxiliary device for stable screw feeding. Background Art

[0002] Taking the application of screw mixing equipment in yarn preparation as an example, when preparing yarn, raw materials and masterbatch need to be mixed. During use, it is found that when the raw materials and masterbatch input from the top feeding cylinder of the traditional screw mixing equipment enter the cavity where the screw is located, some areas of the screw cannot feed in the transfer direction when the materials fall, resulting in a stacking problem. Once stacking occurs, especially when the masterbatch is a colored masterbatch, the color difference rate of the yarn produced by the yarn extrusion preparation equipment after mixing is too high, indirectly reducing the quality of the yarn, and the substandard yarn is difficult to use.

[0003] Based on this, this case is studied and proposed to solve the above problems. Content of the Utility Model

[0004] The utility model provides an auxiliary device for stable screw feeding, which overcomes the deficiencies described in the background art.

A cavity for accommodating raw materials and masterbatch is arranged in the machine body. A feeding port is arranged on the feeding cylinder, and the feeding cylinder is communicated with the machine body. The raw materials and masterbatch are placed from the feeding port and are mixed by the feeding screw and transferred in the conveying direction. A material control baffle is inclinedly installed in the cavity. When the feeding screw rotates and feeds in the cavity, a feeding area and a stacking area are formed on the feeding screw. The material control baffle is covered above the stacking area, so that the raw materials and masterbatch are concentrated and transferred to the feeding area.

[0007] A preferred technical solution: A rotating base is arranged on the back of the material control baffle, and a central rod is penetrated through the rotating base. The central rod is connected with the side surface of the cavity.

The material control baffle 6 is arranged to cover the stacking area, so that the raw materials and masterbatch are concentrated and transferred to the feeding area.

[0029] Embodiment 2

[0030] As Figures 1-6 shown, this embodiment provides an auxiliary device for stable screw feeding, including a feeding cylinder 1, a feeding screw 2, and a machine body 3. A cavity 4 for accommodating raw materials and masterbatch is arranged in the machine body 3. A feeding port 5 is arranged on the feeding cylinder 1, and the feeding cylinder 1 is communicated with the machine body 3. The raw materials and masterbatch are placed from the feeding port 5 and transferred in the conveying direction after being mixed by the feeding screw 2. A material control baffle 6 is installed obliquely in the cavity 4. When the feeding screw 2 rotates and feeds in the cavity 4, a feeding area and a stacking area are formed on the feeding screw 2. The material control baffle 6 is arranged to cover the stacking area, so that the raw materials and masterbatch are concentrated and transferred to the feeding area

[0031] Furthermore, a rotating base 7 is arranged on the back of the material control baffle 6, and a central rod 8 is arranged through the rotating base 7. The central rod 8 is connected to the side surface of the cavity 4.

[0032] Furthermore, a card slot 9 is also arranged on the back of the material control baffle 6, and an adjusting rod 10 is arranged in the card slot 9. An adjusting groove 11 is arranged on the cavity 4. When the adjusting rod 10 moves along the adjusting groove 11, while pushing the material control baffle 6, the material control baffle 6 is adjusted with the central rod 8 as the rotation base point.

[0033] Furthermore, the adjusting groove 11 is arranged in an arc structure.

[0034] Further, an installation plate 12 is provided on the outer side surface of the cavity 4. A first screw thread 13 and a second screw thread 14 are provided on the installation plate 12. A first screw rod 15 is screwed into the first screw thread 13. The installation plate 12 is rotatably installed on the cavity 4 through a convex rod 21.
