Detailed Description

In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. The embodiments of the present application and the features in the embodiments may be combined with each other without collision. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, and the described embodiments are merely some, rather than all, embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to fall within the scope of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

As shown in fig. 1-5, the present scheme specifically discloses a mechanism with crushing and squeezing functions, which is used for extrusion grinding of materials, wherein the materials are mainly materials with high fiber content. The feeding device comprises a feeding cylinder 1 for placing materials, wherein an opening for placing the materials is arranged at the upward end of the feeding cylinder 1, and the materials are placed into a storage bin of the feeding cylinder 1 from the opening. The material conveying and crushing assembly 2 is arranged in the bin, the crushing assembly 2 is of a sectional structure, and the different parts respectively bear the functions of conveying, pre-crushing, finely crushing and discharging the material. One end of the crushed aggregates component 2 is arranged on the wall of the bin and is connected with an external driving component 3, the driving component 3 is a motor, and the crushed aggregates component 2 can be driven to rotate when the motor is started; the other end of the crushed aggregates assembly 2 extends to the outer side of the feeding cylinder 1, and a conical sleeve 4 is sleeved on the periphery of the extending part of the crushed aggregates assembly 2, and the conical sleeve 4 is fixedly connected with the feeding cylinder 1 through screws. In addition, the narrow end of the conical sleeve 4 faces away from the feeding barrel 1, so it can be understood that the conical sleeve 4 is narrowed inwards along the outward end component of the feeding barrel 1, so that along with the grinding, the space capable of containing materials is continuously compressed inwards due to the continuous narrowing, so that the gap 41 between the crushed aggregates component 2 and the inner wall of the conical sleeve 4 is reduced, the extrusion of the materials is tighter, and a better extrusion grinding effect is achieved.

Specifically, the crushed aggregates subassembly 2 includes pivot 20 and grinding portion 21, and wherein grinding portion 21 cover is established in the periphery of pivot 20, and pivot 20 is connected with the motor. When the motor is started, the motor drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the grinding part 21 to rotate. In order to ensure that the rotating shaft 20 can drive the grinding part 21 to rotate together, the rotating shaft 20 and the grinding part 21 are connected in a mode of matching pin keys with pin holes, so that the grinding part 21 can be driven to rotate through the pushing action between the pin keys, and meanwhile, the grinding part 21 is convenient to detach and replace. The grinding part 21 sequentially comprises a discharging section 213, a fine crushing section 212, a pre-crushing section 211 and a feeding section 210 along the length direction, when the materials are poured into the feeding cylinder 1, the materials are sent into the conical sleeve 4 by the discharging section 213, then the materials are roughly ground through the pre-crushing section 211, the materials are divided into small parts, then the materials divided into small parts are subjected to further fine crushing grinding through the fine crushing section 212, and finally the ground materials are sent out of the conical sleeve 4 through the discharging section 213, so that the materials are processed.

Wherein, as shown in fig. 3, the feeding section 210 is arranged in the feeding cylinder 1, so as to be convenient for conveying the poured material into the conical sleeve 4 for extrusion grinding; in addition, the discharging section 213, the fine crushing section 212 and the pre-crushing section 211 are arranged in the conical sleeve 4, and the processes of pre-crushing, fine crushing, discharging and the like of the materials are respectively realized through the extrusion actions of the pre-crushing section 211, the fine crushing section 212, the discharging section 213 and the conical sleeve 4.

It should be noted that, in order to better drive the material to move in the feed cylinder 1 and the conical sleeve 4, threads are provided on the periphery of the feed section 210, the pre-crushing section 211, the fine crushing section 212 and the discharge section 213, and during the rotation of the grinding section 21, the material is moved in the direction of the conical sleeve 4 by the rotation of the threads. Meanwhile, the pitch of the feeding section 210 is larger than that of the pre-crushing section 211, the pitch of the pre-crushing section 211 is larger than that of the fine crushing section 212, and the pitch of the discharging section 213 is not particularly limited, and the principle is that the larger pitch is needed to store the material in the screw thread and push the material to advance due to the larger volume of the material initially put into the feeding cylinder 1; when the material is brought to the pre-crushing section 211, the material needs to be extruded and divided into small parts, so that the screw pitch needs to be further reduced to achieve the aim of extrusion; when the material is divided into small portions, the fine crushing section 212 is required to grind the material further, so that the pitch of the fine crushing section 212 is required to be further reduced to achieve the purpose of fine crushing; finally, after the materials are finely crushed, the materials are processed at the moment, no additional processing is needed, and the material is only required to be carried away by the discharging section 213, so that the pitch of the discharging section 213 is not required to be additionally limited.

In some alternative embodiments, the fine pulverizing section 212 tapers in the direction of the discharge section 213, while the angle at which the fine pulverizing section 212 tapers needs to correspond to the angle at which the conical sleeve 4 tapers in order to ensure that the fine pulverizing section 212 does not interfere with the conical sleeve 4. The aim of this arrangement is that, with further comminution of the material, the material is gradually pushed forward, at which time the space which can accommodate the material is also gradually compressed because the space of the conical sleeve 4 is continuously narrowed, and at which time the material is extruded towards the interior of the conical sleeve 4 and the finely divided sections 212, so that the gradual extrusion of the finely divided sections 212 and the conical sleeve 4 is further enhanced, and further grinding of the material is achieved.

In some alternative embodiments, the grinding portion 21 may be, as shown in fig. 6, in addition to an integral structure, the discharging section 213, the fine crushing section 212, the pre-crushing section 211 and the feeding section 210 are separate modules, and in order to make the discharging section 213, the fine crushing section 212, the pre-crushing section 211 and the feeding section 210 better match with the rotating shaft 20, a first clamping step 200, a second clamping step 201, a third clamping step 202 and a fourth clamping step 203 are sequentially disposed on the rotating shaft 20 towards the direction of the driving assembly 3. During the installation process, the feeding section 210 is matched with the fourth clamping step 203, the pre-crushing section 211 is matched with the third clamping step 202, the fine crushing section 212 is matched with the second clamping step 201, and the discharging section 213 is matched with the fourth clamping step 203. The purpose of the sectional modularization arrangement is that when a certain section of the grinding part 21 is seriously worn and needs to be replaced, only the corresponding section is taken out to be replaced independently, and the whole grinding part 21 is not required to be replaced, so that the replacement cost is greatly saved.

In some alternative embodiments, as shown in fig. 5, the discharging section 213 protrudes partially out of the conical sleeve 4, and an adjusting ram 5 is provided at the end of the conical sleeve 4, where the adjusting ram 5 is tightly fitted with the protruding portion of the discharging section 213, and by adjusting the compression degree of the adjusting ram 5, fine adjustment can be performed on the end of the conical sleeve 4 and the gap 41 of the discharging section 213, so as to adjust the discharging speed of the material.

In some alternative embodiments, during the extrusion process of the material, the water of the material itself is extruded, and if the extruded water is not discharged in time, the water is accumulated in the feeding barrel 1 and the conical sleeve 4, so that the extrusion effect is affected. Therefore, the outer wall of the conical sleeve 4 is formed by splicing a plurality of flat steels 40, a gap 41 for discharging water is reserved between the flat steels 40 and the flat steels 40, and when materials are extruded, the discharged water can flow out of the gap 41 due to extrusion of the materials, so that dry-wet separation between the materials and the water is realized. In order to fix the flat steel 40, a pair of flanges 42 is sleeved on the periphery of the flat steel 40, and the flat steel 40 and the flanges 42 are fixed by welding.

In some alternative embodiments, during actual testing use, it was found that the material would continuously rotate around the periphery of the particle assembly 2 without advancing, due to the relatively smooth inner wall of the conical sleeve 4, with low friction, and the rolling phenomenon would occur. In order to overcome the defect, a stirring bar 43 is arranged in the conical sleeve 4, a plurality of groups of stirring bars 43 are arranged, the stirring bars 43 are circumferentially distributed on the inner wall of the conical sleeve 4, and when materials with the rolling phenomenon pass through the stirring bars 43, the materials are blocked by the stirring bars 43, so that the materials are returned to the thread gap 41 again, and the rolling phenomenon is reduced.

In some alternative embodiments, as shown in fig. 7, the deflector bar 43 may be provided as a plurality of straight bars evenly distributed along the inner wall of the conical sleeve 4.

In some alternative embodiments, as shown in fig. 8, the deflector bar 43 may be provided as a barrier bar spirally distributed along the inner wall of the conical sleeve 4.
