Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-2: the utility model provides a reducing mechanism of methyl cellulose ether raw materials for production, includes rubbing crusher frame 1, and rubbing crusher frame 1's top is that the raw materials opens unit 3, and the bottom is out hopper 2. Crushing frame 1 is equipped with multiunit crushing unit from top to bottom to further smash the raw materials that not smash totally, every group crushing unit has included crushing subassembly 4 and the screening subassembly 5 that links up in proper order, and wherein screening subassembly 5 inclines to arrange, makes the not raw materials that are sieved of upper group in leading-in to the crushing unit of lower group through gravity, and the screening subassembly 5 that can follow the top after the screening falls to the screening subassembly 5 of below.

The raw materials are downwards crushed and sieved for many times, so that the cotton raw materials finally falling to the bottom are basically small in grain size and meet the production requirements.

Specifically, screening subassembly 5 is including the screen cloth 51 that the slope set up, and screen cloth 51 both ends link up to crushing frame 1 inner wall both sides, both obtained the support, can make the raw materials by comprehensive screening again. Meanwhile, the upper end of the screen 51 receives the material above, and the lower end is connected to the next crushing assembly 4. The screen 51 is laterally provided with side walls and extends upwardly to form a receiving barrier 52.

The crushing assembly 4 comprises crushing rollers 41 which are received one after the other, the crushing rollers 41 being driven in rotation by an external motor, wherein the gap between the crushing rollers 41 engages at the discharge opening at the bottom end of the upper screen 51.

Crushing frame 1 is equipped with the package frame 43 that plays the buffer memory effect in every broken round department, is equipped with arc passageway 42 in the package frame 43, reduces the accumulational problem of cotton raw materials appearance in conventional dog-ear for it is more smooth and easy to transmit raw materials. This channel engages the bottom end of the upper screen 51 and the top end of the lower screen 51 so that material that is not completely crushed can be quickly conducted to the lower side for re-crushing and screening.

The top of crushing frame 1 articulates there is flip 6, and flip 6's below department links has commentaries on classics board 7, and one side of commentaries on classics board 7 is equipped with fixed plate 8, forms the cavity of preliminary holding raw materials between the three.

Opening unit 3 is accepted in flip 6 department, opens unit 3 and includes vibrations head 31, and the below array of vibrations head 31 has vibrations needle 32, covers flip 6 back, and vibrations needle 32 is in the cavity.

The turning cover 6 and the rotating plate 7 are linked through a rotating component, wherein the rotating component comprises two gears 9 which are hinged with each other, the gears 9 are pivoted on the crushing machine frame 1, and one sides of the turning cover 6 and the rotating plate 7 are respectively connected on the side walls of the corresponding gears 9 through extending plates 10 so as to rotate reversely along with the two gears 9. Specifically, when the turning cover 6 is opened, the rotating plate 7 is turned downwards by combining the meshing effect of the two gears 9, so that a gap is formed between the rotating plate and the fixing plate 8, cotton raw materials are placed, and the turning cover 6 is closed to open through the vibrating needle 32. It should be noted that, because the cotton itself has a certain volume and has a certain adhesion property without opening, a part of the cotton is clamped between the rotating plate 7 and the extending plate 10, and only a small part of the cotton falls below the rotating plate 7 and is not opened, but the influence on the subsequent crushing is negligible.

The above embodiments are intended to teach that various changes and modifications may be made by persons skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the description, and the protection scope must be determined by the scope of the claims.
