It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] The utility model provides a kind of spiral press prevents material skidding and holds shaft device, including poking wheel 3, the poking wheel 3 rotation is installed at the feed inlet 1 of spiral press 6, can directly intervene in the initial stage when material enters spiral press 6, reduce the skidding phenomenon in the pressing process of material, improve pressing efficiency.The feed inlet 1 of spiral press 6 is equipped with feed shell 2, the poking wheel 3 passes through feed shell 2 and the spiral blade corresponding at feed inlet 1, ensure that poking wheel 3 can effectively work with spiral blade 7, enhance the control of material, promote forward and reduce backflow and skidding.

[0025] The poking wheel 3 is equipped with the poking groove 4 corresponding with the spiral blade 7 of spiral press 6, and the poking wheel 3 is equipped with 3-8 poking grooves 4. The poking groove 4 is semicircular near the rotating shaft end of the poking wheel 3, and the semicircular design helps to smooth the flow of material, reduce the friction between the material and the poking wheel, and reduce the possibility of skidding. The rotation rate of the poking wheel 3 is equal to the rotation rate of the spiral blade 7, ensuring the continuity and uniformity during the pressing process, and avoiding material accumulation or skidding due to speed mismatch. When the spiral blade rotates, the poking wheel rotates downward, achieving the effect of pressing the material and further reducing the backflow of the material.

[0026] The poking wheel 3 forms a poking piece 5 between the two poking grooves 4, and the poking wheel 3 is arranged at the upper end of the spiral blade 7. The spiral blade 7 includes a plurality of spiral sub-blades mounted on a spiral shaft, and each spiral sub-blade rotates one full circle along the spiral shaft, i.e., 360° of spiral. The poking piece 5 is always arranged between two spiral sub-blades, and the poking piece 5 extends into the space between the two spiral sub-blades, effectively preventing the phenomenon of holding the shaft and improving the efficiency of pressing.

[0027] The rotation of the poking wheel 3 has two forms: passive, the poking wheel 3 rotates with the rotation of the spiral blade 7, which can reduce costs while ensuring effectiveness. The other is active, the rotating shaft 8 of the poking wheel 3 is connected with the poking wheel motor, which prolongs the service life of the poking wheel 3.

[0028] The poking wheel 3 is provided with a poking wheel shell 7 outside, which provides additional protection to prevent material from splashing and equipment damage, and also helps to keep the inside of the spiral press 6 clean. The poking wheel shell 7 is installed at one end of the feed shell, and the poking wheel shell is installed on the upper end of the spiral channel of the spiral press.

[0029] The present invention enhances control over the material through the coordinated work of the dial wheel and the spiral blades, significantly reducing the slippage of the material during the pressing process, thereby improving the pressing efficiency.

The matching of the rotation speed of the dial wheel and the spiral blades ensures the continuity and uniformity of the pressing process, avoids material accumulation or slippage caused by speed mismatch, and ensures the stability of the pressing process. The dial piece is always set between the two spiral blades, which effectively prevents the shaft from sticking, reduces material backflow, and improves the pressing efficiency. The two rotation modes of the dial wheel, passive and active, provide flexibility and cost-effectiveness, while extending the service life of the dial wheel. The setting of the dial wheel housing provides additional protection for the equipment, preventing material splashing and equipment damage, and helps to keep the equipment clean and maintain the stability of the equipment.
